Funding details Abstract Berberine (BER) is a benzylisoquinoline alkaloid found in many plants. It has high water solubilitybut its bioavailability is low in oral administration due to the first-pass effect in the liver and intestine. Phytosomesare are prepared by complexing herbal active ingredients and phospholipids (PLs). The aim of this study is to prepare BER-phospholipidcomplexes (BPCs) using the reverse phase evaporation method. In the preparation of the formulations, the effects of BER:PL ratio (w/w), reaction temperature (°C) and reaction time (h) on the specifications of the complexes such as particle size (PS), zeta potential (ZP) and encapsulation efficiency (EE%) were investigated. The distribution of PS of obtained complexes was ranging between 339-1259 nm and their ZP were within-4,27--5,15 mV. The drug EE% was relatively high. Quality by Design (QbD) methods have been used in the formulation design and selection of the optimum formulation. BPCs anti-inflammatory, analgesic and antipyretic activities are evaluated by using in vivo methods.Carrageenan-, Prostaglandin E2 (PGE2)-and serotonin-induced hind paw edema, acetic acid-induced increase in capillary permeability and subcutaneous air-pouch models for the anti-inflammatory activity, inhibition of p-benzoquinone-induced abdominal constriction and hot plate test for the analgesic activity, Freund’s complete adjuvant-induced pyrexia model for the antipyretic activity were used in mice and rats. Results showed that BPCs showed potent anti-inflammatory, analgesic and antipyretic activities at the dose of 209 mg/kg.

Perillus bioculatus (Fabricius, 1775) —Two-spotted Stink Bug (Fig. 5) Distribution in Turkey (Map 5): Amasya, Ankara, Edirne, Kırklareli, Tekirdağ (Kıvan 2004; Fent & Aktaç 2007; Dursun & Fent 2018; Kıyak et al. 2019); Bolu, Kastamonu, Zonguldak (this study). New records by citizen scientists in Turkey: 1. Amasya: Merzifon, 25.VII.2017 (Şeker 2017). 2. Bolu: road to Avdan Village, 16.XI.2020 (Okur, 2020). 3. Kastamonu (centre), 14.VI.2016 (Yaşayacak 2016). 4. Zonguldak (centre), 14.X.2019 (Aşar 2019). Comments: P. bioculatus is originally a Nearctic species (Rabitsch 2008) and it was introduced to Algeria, Greece, Serbia and Turkey in Europe (Aukema 2021). This alien insect was firstly reported from Tekirdağ in 1997 (Kıvan 2004). However, the oldest material in Turkey was collected in Edirne in 1993 (Fent & Aktaç 2007). Later, its distribution range expanded in the West and Central Black Sea and also Ankara in Central Anatolia (Dursun & Fent 2018; Kıyak et al. 2019; this study). Probably it may appear in the provinces in between these regions. Therefore, additional observations are needed. Two of the new records were obtained in mid-summer (June, July) and the other two in autumn (October, November) (Graph 5)., Published as part of Çerçi, Bariş, Karataş, Ahmet & Karataş, Ayşegül, 2021, Insecta non gratae: New Distribution Records of Eight Alien Bug (Hemiptera) Species in Turkey with Contributions of Citizen Science, pp. 1-28 in Zootaxa 5057 (1) on pages 10-11, DOI: 10.11646/zootaxa.5057.1.1, http://zenodo.org/record/5585486, {"references":["Kivan, M.

Its first record for Europe was given from Italy in 2000 (Bernardinelli & Zandigiacomo 2000). The bug later spread to many other European countries including Albania, Austria, Bosnia and Herzegovina, Bulgaria, France, Hungary, Croatia, Greece, Romania, Russia, Serbia, Slovenia, Slovakia, Switzerland, Ukraine, and also Iran (Forster et al. 2005; Ghahari et al. 2010; Csóka et al. 2019). The first record in Turkey was given from Bolu Province in 2002 (Mutun, 2003). The bug, called “meşe kaplanı” in Turkish, spread to almost all the neighbouring provinces in a few years (Mutun et al. 2009). It reached Kastamonu in 2013 (Küçükbasmacı 2014), Central Black Sea and Mediterranean regions of Turkey in 2014 (Aytar et al. 2014). According to 17 new records from 13 localities, the activity period of C. arcuata ranges from May to November and it has been seen in August and September with a maximum of five records each (Graph 2).

Zonguldak: Alaplı, 09.IX.2014 (Yaşayacak 2015). Comments: S. bisonia is native to the central and eastern part of North America (Walczak et al. 2018). It was classified formerly as Ceresa bubalus (Fabricius, 1794) (Walczak et al. 2018). However, Andrade (1997) regarded it as a synonym of Stictocephala alta (Walker, 1851). This alien species was transported to eastern central Europe from North America and it was found for the first time in Serbia before 1912 (Walczak et al. 2018). It spread in most of the countries from Portugal to Azerbaijan in the Western Palearctic. As in North America, it is distributed just north of 50 o N latitude in Europe (Schedl 1991; Walczak et al. 2018). This insect was reported from Edirne in 1963 as Ceresa bubalus by Lodos & Kalkandelen (1981). Although it is the oldest introduced species among the eight bug species considered in the present study; the number of provinces in which it was reported is low, as there is not much work on it or alternatively, its spreading speed may be low in Turkey. It is mostly seen in Marmara and Eastern Black Sea provinces. There are 13 records from 11 localities (Map 7). Most of them were in autumn, with five records each in September and October (Graph 7).

Çaycuma, Burunkaya, 08.VIII.2016 (Yangın 2016b). Comments: Native distribution of M. pruinosa is in the Nearctic region (Zangheri & Donadini 1980; CABI 2019). This invasive bug was accidentally introduced from North America to Italy in 1979 (Zangheri & Donadini 1980). It has now been detected in 19 European countries (CABI 2019). The species was firstly recorded from İzmir in 2003 (Karsavuran & Güçlü 2004). It was photographed three years later in 2006 by Saim Dağ from İstanbul (Dağ 2018). In the following years, it was seen in the Marmara Region and the Black Sea coastal provinces up to Giresun in the east (Map 8). Eighteen records were obtained from 14 localities (Graph 8). Accordingly, it was mostly seen in August (n= 9). A total of eight hemipteran species were reported from 50 provinces of Turkey. The most common species was Leptoglossus occidentalis reported from 40 provinces. The number of provinces where other species were observed is as follows: Corythucha arcuata (21), Zelus renardii (15), Metcalfa pruinosa (14), Halyomorpha halys (14), Stictocephala bisonia (13), Perillus bioculatus (8), and Corythucha ciliata (6). The highest diversity of species was in Bursa province where all species except Perillus bioculatus were found. Ankara and İstanbul share second place with six species. There were five provinces with five species (Bolu, Eskisehir, Kırklareli, Samsun, Zonguldak), nine provinces with four species (Amasya, Artvin, Edirne, Giresun, İzmir, Kastamonu, Sakarya, Tekirdağ, Yalova), five provinces with three species (Balıkesir, Bartın, Düzce, Ordu, Trabzon), eight provinces with two species (Antalya, Aydın, Bilecik, Denizli, Muğla, Rize, Sinop, Tokat) and 20 provinces with one species (Adana, Afyonkarahisar, Ardahan, Burdur, Çanakkale, Çankırı, Çorum, Diyarbakır, Elazığ, Erzurum, Isparta, Karabük, Kayseri, Kocaeli, Kütahya, Manisa, Mersin, Niğde, Osmaniye, Uşak) (Tab. 1). When records in Table 1 are examined, the number of provincial records is 131, 77 of which are presented in the previous literature. A total of 80 provincial records were obtained from citizen science, corresponding to more than those provided by the scientific literature in the intervening 58 years since the earliest record from 1963. Among these, 26 provincial records were previously mentioned in the literature and 50 provincial records are new meaning that the corresponding species was not reported from that province before. When the dates of the records are considered, there are 54 new provincial records in total since four provincial records were obtained by citizen scientists earlier than the previous literature records. These results show that citizen science is an important contributor as a data source, and it provides remarkable contribution for increasing the understanding on expansion of invasive species as well as providing clear picture on their distribution., Published as part of Çerçi, Bariş, Karataş, Ahmet & Karataş, Ayşegül, 2021, Insecta non gratae: New Distribution Records of Eight Alien Bug (Hemiptera) Species in Turkey with Contributions of Citizen Science, pp. 1-28 in Zootaxa 5057 (1) on pages 15-17, DOI: 10.11646/zootaxa.5057.1.1, http://zenodo.org/record/5585486, {"references":["Karsavuran, Y. & Guclu, S.

Its first European record was given in Italy in 1999. The distribution of this bug rapidly expanded to eastern and western Europe from Italy and now it is very common and widespread throughout the continent, and known from Albania, Algeria, Austria, Belgium, Bulgaria, China, Croatia, Crete, Czech Republic, Denmark, France, Finland, Georgia, Germany, Great Britain, Greece, Hungary, Ireland, Italy, Japan, Kazakhstan, Kosovo, Lebanon, Luxembourg, Macedonia, Malta, Moldavia, Montenegro, Morocco, Netherlands, Norway, Palestine, Poland, Portugal, Romania, Russia, Serbia, Slovakia, Slovenia, Spain, Switzerland, Syria, Tunisia, Turkey, and Ukraine, as well as Central and South America and South Africa (Arslangündoğdu & Hızal 2010; Fent & Kment 2011; Aukema 2021). It reached Turkey a decade later following its first record in Europe and reported from the European side of İstanbul province in 2009 (Arslangündoğdu & Hızal 2010). It was observed from Edirne (Fent & Kment 2011) and Yalova (this study) in the same year. It spread toward southwestern Turkey over Balıkesir in 2011 (Dursun 2016) and İzmir in 2012 (Hızal & İnan 2012) and arrived to Antalya in 2014 (this study). According to new data, it was also seen in Samsun in 2014, in Çorum and Tokat in 2015. Its occurrence in the surrounding provinces in the following years is probably due to the lack of observation. According to 89 records given from 81 localities in the present study, it is seen all year except December. With 43 records, almost half of the total was obtained in October (Graph 4). GRAPH 4.

Comments: H. halys is native in East Asia and ranges in China, Japan, Korea and Taiwan (Rabitsch 2008). It is found firstly in North America and Chile as an invasive insect species. This bug was introduced to Europe in 2004 for the first time and spread to many European countries including Austria, Croatia, Germany, France, Hungary, Italy, Liechtenstein, Romania, Russia, Serbia, Switzerland, Slovakia, Slovenia, Spain, and Sweden (Cianferoni et al. 2018). It was recorded from Greece in 2011, from Georgia in 2015 and from Bulgaria in 2016 (Cianferoni et al. 2018; Özdemir & Tuncer 2021; Çerçi 2021). Following these records from neighbouring countries, it arrived in Turkey and it was firstly discovered in İstanbul in 2017 (Çerçi & Koçak 2017). According to the records given later, the oldest record in Turkey is from Artvin in 2016 (Göktürk & Tozlu 2019). It seems, from these records, that this species spread to Turkey both from Georgia through Artvin and from Europe through İstanbul. According to new data, H. halys can be found year-round, but it is most common in autumn. Eleven of the 31 records were reported in October (Graph 6). GRAPH 6.

Isolated records from Denmark, Germany and United Kingdom do not currently prove stable colonisation in these regions (van der Heyden 2021). The first record of Z. renardii from Turkey was given from İzmir in 2015 and İstanbul in 2016 (Çerçi & Koçak 2016). With the new records presented above, this species is known from 15 provinces in Turkey (Map 1). According to the new records given here, Z. renardii is active all year round in Turkey. However, it was mostly seen in October, with 19 of 73 records (Graph 1). GRAPH 1.

The Harlequin Ladybird, Harmonia axyridis (Pallas, 1773), is native to Eastern Asia but it has been introduced to many countries in Africa, America, and Eurasia. In Turkey, H. axyridis is one of the most fast-spreading invasive alien species. Since the collection of the first specimens in 2010, H. axyridis spread almost all over the country. The species spreads fast in Turkey according to the new records, obtained originally from the field studies and the citizen science data. It was recorded for the first time from 19 of 81 Turkish provinces (Ankara, Antalya, Balıkesir, Bolu, Bursa, İstanbul, İzmir, Karaman, Kastamonu, Kırklareli, Kocaeli, Muğla, Rize, Samsun, Sinop, Tokat, Trabzon, Yalova, and Zonguldak) from Aegean, Central and Eastern Black Sea regions. We used the MaxEnt program to predict the current and future potential geographical distribution of this species in Turkey and its surrounding areas. Based on MaxEnt predictions, the majority of this region seems highly suitable for the species.

Inhigher education, the evaluation of the instructors by students has become acommon practice over the years. These evaluations which are generally based on questionnairehave been accepted as inputs in decisions regarding quality improvement ineducation. On the other hand, some researchers suggest that questionnaires may producedeviant results by the effect of some factors except the performance of theinstructor. Among these factors, it is claimed that there are variables relatedto the course taken, variables related to the instructor other than teachingperformance and class differences.Theprimary objective of the paper is to discuss whether class differences have animpact on the differences have an impact on the factors determining thesatisfaction with instructors. The data set of the study consists ofquestionnaires in which all students at International Trade Department of SakaryaUniversity Business School taking courses in all semesters between 2014 -2018evaluate the lecturers of each semester and thus longitudinal data is used inthe study.There are two different classes and who attendedto all the courses of the program one year apart. According to results significant differences on the factorsdetermined between the students in different classes were observed., Yükseköğretimde,alınan derslerin ve derslerin öğretim elemanlarının dersi alan öğrencilertarafından değerlendirilmesi her geçen gün yaygınlığı artan bir uygulamadır.Yazında, değerlendirilen anketlerin öğretim elemanının performansı dışında bazıfaktörler etkisinde sapmalı sonuçlar verebileceğine dair tartışmalarbulunmaktadır. Bu faktörler arasında alınan dersle ilişkili değişkenler,öğretim elemanı ile ilgili öğretim performansı dışındaki değişkenler ve sınıffarklılıklarının olduğu öne sürülmektedir.Bu araştırmanın amacısınıf farklılıklarının öğretim elemanlarına yönelik memnuniyeti belirleyenfaktörler üzerinde bir etkisi olup olmadığını tartışmaktır. Araştırmanın verisetini, Sakarya Üniversitesi Uluslararası Ticaret Bölümü’nde 2014 yılından 2019yılına kadarki tüm dönemlerde ders alan öğrencilerin her dönem derslerinöğretim üyelerini değerlendirdiği anketler oluşturmaktadır ve böylece çalışmadayazındakinin aksine boylamsal veri kullanılmaktadır. Öncelikle bir yılarayla bölüme kaydolan ve birinci dönemden yedinci döneme kadar alınan tümdersleri değerlendirilen iki ayrı sınıfın verileri incelenerek açıklayıcıfaktörler karşılaştırılmaktadır. İkinci olarak da farklı sınıf düzeylerindekiöğrencilerin öğretim üyelerine yönelik memnuniyetlerini belirleyen faktörlerinfarklılaşıp farklılaşmadığı araştırılmıştır. Analiz sonucunda bu iki sınıfınöğretim üyelerine yönelik memnuniyetini belirleyen faktörler ve bu faktörlerinyükleri arasında önemli farklılıklara rastlanmamıştır. Ancak tespit edilenfaktörlerde ise farklı sınıflarda bulunan öğrenciler arasında önemlifarklılıklar olduğu gözlemlenmiştir. Bu bulgudan yola çıkarak birinci sınıftandördüncü sınıfa kadar devam eden öğrenim süresince öğrencilerin beklentilerininfarklılaştığı görülmektedir.

An important part of the active ingredients derived from plants has long side chains and high polarity. This prevents absorption through passive diffusion from the gastrointestinal mucosa or skin. At this point, the new complexing technique called "phyto-phospholipid" or "phytosome" plays an important role in facilitating absorption and increasing bioavailability. Phytosomes are structures formed as a result of the fact that active ingredients of plant origin form complexes with natural phospholipids such as soy lecithin in a suitable solvent / solvent system. In order to make the characterization of phytosome formulations, in vitro tests such as particle size measurement, active substance release rate determination, melting point determination are performed. Encapsulation efficiency is another parameter that is evaluated by measuring. It is the expression of the active substance in the formulation in %. It can also be obtained by measuring the free active component that cannot be kept in the phytosome structure by a suitable method. In this study, it was aimed to develop HPLC method and analytical validation to determine the amount of berberine in phytosome formulations. HPLC analyzes were carried out in the Zorbax Eclipse Plus C18 (100 mm x 4.6 mm x 3.5 µm) column on Agilent 1260 Infinity II device at a flow rate of 1 mL / min. In order to determine the berberine from the phytosome formulation, the HPLC quantification method was developed and validated according to the relevant ICH guidelines. It is important to be able to determine the amount of berberine by separating the excipients in the phytosome formulations. Therefore, specificity from analytical validation parameters has been evaluated in detail. The developed method was evaluated in terms of specificity, linearity and range, accuracy and precision parameters. It has been determined that the developed method is reliable for quantification of berberine in phytosome formulations., Bitkilerden elde edilen aktif bileşenlerin önemli bir bölümü, uzun yan zincirlere ve yüksek polariteye sahiptir. Bu da gastrointestinal mukozadan veya deriden pasif difüzyonla emilime engel teşkil etmektedir. Bu noktada, ‘fito-fosfolipid’ veya ‘fitozom’ olarak adlandırılan yeni kompleksleştirme tekniği, absorbsiyonu kolaylaştırmak ve biyoyararlanımı artırmakta önemli bir rol oynamaktadır. Fitozomlar, bitkisel kaynaklı etkin maddelerin soya lesitini gibi doğal fosfolipidlerle uygun bir solvan/solvan sisteminde kompleks oluşturması sonucu oluşan yapılardır. Fitozom formülasyonlarının karakterizasyonlarının yapılması amacıyla partikül boyutu ölçümü, etken madde salım hızı tayini, erime noktası tayini gibi in vitro testler yapılır. Enkapsülasyon etkinliği de ölçümü yapılarak değerlendirilen bir diğer parametredir. Formülasyon içinde tutulan etken maddenin %’de olarak ifadesidir. Bu çalışmada fitozom yapısında tutulamayan serbest aktif bileşenin uygun bir yöntemle ölçülmesi sonucu elde edilmiştir. Çalışmada fitozom formülasyonlarındaki berberin miktarını tayin etmek amacıyla HPLC metodunun geliştirilmesi ve analitik validasyonunun yapılması amaçlanmıştır. HPLC analizleri Agilent 1260 Infinity II cihazında Zorbax Eclipse Plus C18 (100 mm x 4.6 mm x 3.5 µm) kolonda, 1 mL/dk akış hızında yapılmıştır. Berberin fitozom formülasyonundan berberinin miktar tayininin yapılması amacıyla HPLC miktar tayini yöntemi geliştirilmiş ve ilgili ICH kılavuzuna göre valide edilmiştir. Berberinin fitozom formülasyonlarında bulunan yardımcı maddelerden ayrılarak miktar tayinin yapılabilmesi önemlidir. Bu noktada analitik validasyon parametrelerinden özgünlük detaylı olarak değerlendirilmiştir. Geliştirilen yöntem özgünlük, doğrusallık ve aralığı, doğruluk, kesinlik, geri elde edilebilirlik parametreleri yönünden değerlendirilmiş ve berberinin miktar tayini için güvenilir olduğu belirlenmiştir.

Uluslararası pazar seçimi (UPS) hem akademide hem de iş dünyasında oldukça tartışılan bir konudur. En yüksek pazar fırsatını barındıran uluslararası pazarları tespit edebilmek amacıyla çok sayıda model geliştirildiği görülmektedir. Ancak bu modellerin pek çoğu teorik alt yapıdan yoksun, ampirik olarak test edilmemiş ya da uygulama kolaylığı bulunmayan modellerdir. Bu çalışmada öncelikle yazındaki modeller; parsimoni, uygulanabilirlik, genellenebilirlik, sektör bazlı ve teorik altyapı kriterlerine göre değerlendirilmektedir. Bu değerlendirmeler sonrasında; Faktör Donanımı Teorisi, Çekim Modeli, Kaynak Temelli Yaklaşım ve Ürün Yaşam Döngüsü teorilerinden temellerini alan "küresel rekabetin yüksek olduğu ürün/sektörlere özel" bir UPS modeli geliştirilmektedir. Bu modelde çok kriterli pazar temelli yaklaşımlarda kullanılan değişkenler ve Net Pay Kayması Analizi eşzamanlı kullanıldığından model "Bütünleşik Model" olarak adlandırılmıştır. Bu çok kriterli modelin özgün yönleri; ürüne özel rekabet değişkenini içeriyor olması, değişkenlerinin verilerinin kamuya açık olması ve diğer modellere nazaran uygulamasının kolay olması şeklinde özetlenmektedir. Bütünleşik Model beş farklı örneklemde ve iki farklı zaman diliminde test edilmiştir. Sonrasında ise Global Edge Sektör Bazlı UPP Modeli ve Papadopoulos'un (2002) Seçim Modeli ile aynı örneklemlerde uygulanarak tahminleme güçleri karşılaştırılmıştır. Bu modellerin tahminleme güçlerinin karşılaştırılmasında hem ihracat büyüklüğünü hem de ihracat büyümesini eş zamanlı ölçümleyebilen NPKA'nın revize edilmiş bir versiyonu kullanılmıştır. Tahmin yılı sonrasındaki üç yılda gerçekleşen ihracat tutarlarının hepsini değerlendiriyor olması nedeniyle bu değişken pazar fırsatını standart NPKA'ya nazaran daha doğru bir şekilde ölçümlemeye olanak sağlamaktadır. Elde edilen bulgular, Bütünleşik Model'in uluslararası pazar fırsatlarını belirleme konusunda geçerli olduğunu ve diğer modellere nazaran daha yüksek tahminleme gücünün bulunduğunu göstermektedir. Ancak dış ticaret verilerindeki güvenilirlik probleminin model sonuçlarını saptırıyor oluşu önemli bir kısıttır. Bu nedenle özellikle gelişmekte olan ülkelere uygulandığında sonuçların dikkatle değerlendirilmesi gerektiği vurgulanmaktadır. Bütünleşik Model'de hem bağımlı hem de bağımsız değişken olarak kullanılan dış ticaret verilerinin hem ithalatçı hem de ihracatçı ülke tarafından raporlanıyor oluşu nedeniyle güvenirlik konusunda fikir edinmek mümkündür. Bu anlamda ileride yapılacak olan araştırmalarda bu yönde ilerleme sağlanması önerilmektedir. International market selection (IMS) is a topic that is highly discussed in both academia and business world. Numerous models have been developed in order to identify the international markets with the highest market opportunity. However, many of these models are lack of either theoretical background, ease of application or empirical testability. In this study, the models in the liretature are critized according to the criteria of parsimony, applicability, generalizability and theoretical background. Following these evaluations; a UPS model is developed for products / sectors which are exposed to high competition in global area. The model is based on theories of Factor Endowment, Gravity Model, Resource Based Approach and The International Product Life Cycle Theory. In this model, both variables of multi-criteria market-based approaches and the Net Shift Share Analysis are used. So that the model is called Integrated Model. The original aspects of this multi-criteria model can be summarized as; contex of product based global competition, variables which are publicly available, easiness of the technique and adaptability to any kind of product. The Integrated Model is tested in five different country-product samples in two different periods of time. After that, the forecasting power of Integrated Model is compared with Sector-Based International Market Potential Index (Global Edge, 2017b) and Trade Off Model (Papadopoulos vd., 2002) in the same samples. The dependent variable used in these tests is a revised version of Net Shift Share Analysis. In this version the exports realized in there years after the forecast year, are considered. So, this variable provides a more accurate market opportunity measurement. In the findings it is seen that Integrated Model is valid and has a more powerful forecasting ability than the other models. However, the fact that the reliability problem in secondary data distorts the model results is an important constraint. Therefore, it is emphasized that the results should be evaluated carefully especially when applied to developing countries. International trade data which is used in the calculation of both dependent and independent varibles of the model are reported by both the exporting and the importing countries. Consequently, it is possible to take the measure of reliability. In the future researches, improvement in this area is recommended.

- Abstract
The invasive species Orosanga japonicawas found at 38 sites in Black Sea coastal zone of Turkey. It was recorded for the first time from the Central Black Sea Region, and for the second time from Western Black Sea Region and in the European part of Turkey. Most localities were close to the Black Sea (<3 km) and situated at altitudes lower than 150 m a.s.l. with the highest records up to 500 m a.s.l. Maximum distance from the sea was in Alemdağ, with c. 15 km, and Erenköy, with c. 10 km. This species is confined in Turkey to the high-rainy and humid coastal zones. Additionally considering cultivated plants, O. japonicawas found on 18 host plant species, of which 15 were previously not known to be used by the species. Nymphs of this univoltine pest were found between May and July, depending on the weather conditions such as rainfall and temperature. Adults emerged between early June and mid-September, with the highest density in the second half of August. Eggs were observed from late August to mid-June.

Küresel marka sahip olduğu "küresellik" özelliği nedeniyle bazı konularda diğer markalardan ayrılmaktadır. Ancak kavramsal açıdan küresel marka farklı ekoller tarafından farklı şekillerde tanımlanmaktadır. Akademisyenlerin bile tanımı üzerinde uzlaşı sağlayamadığı bu kavram tüketicilerin zihinlerinde ne şekilde yer almaktadır? Tüketicilerin bu markaları diğerlerinden ayırt edip edemedikleri küresel marka yazınını birçok açıdan özellikle de örneklem seçiminde etkileyebilecek bir konudur. Bu bağlamda araştırmada öncelikle tüketicilerin küresel markaları ne derece ayırt edebildikleri incelenmektedir. Sonrasında bu markalara yönelik tutumların ne yönde olduğu ve bu tutumların bu markaları tercih etme/etmeme konusunda ne derece etkili olduğu saptanmaya çalışılmaktadır. Araştırmanın örneklemini Türkiye'de yaşayan 18 yaş ve üstü tüm tüketiciler oluşturmaktadır. Bu evrendeki gruptan örneklem seçiminin rassal yapılmasının zorluğu ve maliyeti araştırmanın en önemli kısıtıdır. Veri toplama tekniği ankettir. Anketlerden elde edilen veriler nicel analiz teknikleri ile analiz edilmiştir. Araştırmaya göre küresel markalara yönelik tutumlar, diğer markalara nazaran daha olumludur. Küresel markalara yönelik tutum ile küresel marka tercih istekliliği arasında pozitif bir ilişki vardır. Bu tutumları etkileyen faktörlerden bazıları ise bu markalardan beklenen fayda, küreselleşmeye yönelik tutumlar, küresel firma husumeti, tüketici etnosentrizmi, materyalizm ve dikey bireycilik olarak sıralanabilir. Ancak, tüketiciler küresel marka bilinç düzeyi düşük ve yüksek olarak sınıflandırıldığında, bulgularda bir takım farklılıklara ulaşılmıştır. Dolayısıyla, ileride yapılacak küresel marka araştırmalarında örneklem seçiminde bu husus dikkate alınmalıdır. Due to the global nature of them, global brands differ from ordinary brands in many respects. But it seems that there is a lack of consensus on the definition of global brands and different schools have proposed different definitions depending on their views. This is no exception among academics. In such a complicated and vague context, consumers' global brands perceptions are of significant implications for international marketing as well as academic endeavors. Hence consumers' ability of differentiate global brands from others may have implications for the validity of existing findings in the global brand literature. That is, the sampling frame used in academic studies may have significant effects on the findings. To this end, in this study we sought respondents' ability to differentiate between the global brands and the others. Then consumers' attitudes towards global brands and the factors affecting these attitudes are examined. The universe of the study is the Turkish consumers with an age of 18 and over. The cost and the difficulty of choosing a random sample from this universe is the main constraint of the study. Data was collected via a questionnaire. The data collected by means of surveys is analyzed with the quantitative methods. Findings indicate that, in general, attitudes towards global brands are more favorable than the attitudes towards the others. In addition, there is a positive relationship between attitudes towards global brands and willingness to choose these brands. Among the factors affecting consumers' attitudes are the expected benefits from these brands, attitudes towards globalization, global company animosity, consumer ethnocentrism, materialism and vertical individualism. Results have shown that consumers' level of awareness of global brands tend to influence their attitudes towards global brands.

Modern anlayışta başarılı yara tedavisi, yara çevresinde nemli bir ortam oluşturulmasına dayanmaktadır. Dengelenmiş neme sahip ortam, hücresiz matriste hücresel büyümeyi kolaylaştırdığı gibi kollajen üretimini de artırmaktadır. Bu sebeple etkin yara tedavisi amacıyla modern yara örtüleri, epitel hücrelerin bağımsız hareket etmesine izin veren optimum koşulları sağlamak üzere tasarlanmaktadır. Aynı zamanda, ideal yara örtüsü hastaya en az rahatsızlık vererek en kısa sürede yara iyileşmesini gerçekleştirmek için, hücrelerin yenilenmesine olanak sağlayacak şekilde etkin oksijen sirkülasyonu da izin vermelidir. Yara tiplerinin çeşitliliği yara örtülerinin de çeşitliliğini artırmıştır. Bu derleme, etkin yara tedavisine ulaşmak için geliştirilen yeni teknolojilerden bahsetmektedir. Ayrıca modern yara örtülerine ve yaraya ilaç salımı için kullanılan yeni polimerik sistemlere de yer vermektedir. Yara iyileşme sürecinde aktif rol oynayan, antibiyotikler, vitaminler, mineraller ve büyüme faktörleri gibi farmasötik etken maddelerden ve tedavi hızlandırıcılardan bahsedilmiş, bu ajanların yaraya lokal olarak uygulanması ve kontrollü salımının avantajları tartışılmıştır. Bunlara ek olarak modern yara tedavisinin güncel gelişim ve gereksinimlerine dayanarak, doku mühendisliği ürünleri olarak kullanılan biyoaktif polimerler ve deri greftleri ile ilgili kısa bir bölüme de yer verilmiştir, In modern aspect, successful wound healing depends on maintaining a moist environment around the wound. A balanced moist environment facilitates cellular growth and collagen proliferation within acellular matrix. Therefore the modern dressings are based on the concept of creating optimum conditions to allow epithelial cells to move unimpeded for the treatment of wounds. The ideal dressing should also provide effective oxygen circulation to aid regenerating cells for rapid healing with minimal inconvenience to the patient. The variety of wound types has resulted in a wide range of wound dressings. This article offers a review of the emerging technologies for achieving improved wound healing. It also reviews many of modern wound dressings and novel polymeric systems used for the delivery of drugs to the wounds. Pharmaceutical agents and wound healing accelerators such as antibiotics, vitamins, minerals and growth factors that take active part in the healing process and also the advantages of local delivery and controlled release of these agents are discussed. Furthermore a brief section about the use of bioactive polymers as tissue engineered scaffolds and skin grafts is given a part regarding current developments and requirements of modern wound therapy

Mikrofabrikasyon mikrometreden milimetreye değişen boyutlarda objeler yaratmak için kullanılan bir işlemdir. Bu objeler minyatür hareketli parçalara, durağan yapılara ya da herikisine de sahiptir. Yapısal, mekanik ve belki de elektronik özelliklerin kombinasyonuyla terapötik ilaç taşıyıcı sistemlerinin yaratılmasına izin veren mikrofabrikasyon teknikleri ile klasik ilaç taşıyıcı sistemlerle yapılan tedavi hedeflerinin üstesinden gelinebilir. Bu derlemede, mikrofabrikasyon teknikleri kısaca tanımlanmıştır ve salım kavramları da mikrofabrikasyonun önemi üzerinde durularak sunulmuştur. Olası uygulamalar, transdermal etkin madde salımı için mikroiğneleri, lokal etkin madde salımı için implant, mikroçip, mikrovalf ve mikropompaları, oral etkin madde salımı için biyoadezif mikropartikülleri ve diyabetin olası tedavisi için immünizole biyokapsülleri içermektedir. Buna ilaveten, tamamiyle entegre olmuş ve kendi kendini kontrol edebilecek gelecek jenerasyon ilaç taşıyıcı sistemler de tartışılacaktır, Microfabrication is a process used to create the objects with dimensions in the range of micrometers to milimeters. These objects can have miniature moving parts, stationary structures, or both. Microfabrication techniques, which permit the creation of therapeutic delivery systems that posses, a combination of structural, mechanical, and perhaps electronic features may surmount challenges associated with conventional delivery of therapy. In this review, microfabrication techniques are described briefly, and delivery concepts are also presented which capitalize on the strengths of microfabrication. Possible applications include microneedles for transdermal drug delivery, implanted microchip, microvalve and micropomps for localized drug delivery, bioadhesive microparticles for oral delivery and immunoisolating biocapsules as a possible treatment for diabetes. In addition, the next generation of drug delivery systems fully integrated and self-regulating will be discussed

Hidrojeller suyu ya da biyolojik sıviları büyük miktarlarda içen ve böylece büyük çapta biyolojik dokuya benzeyen hidrofilik ve üç boyutlu ağlardır. Özellikle poli(2-hidroksietil metakrilat) ve poli(2hidroksipropil metakrilat) hidrojellerinin iyi-tolere edilme emniyeti ve biyogeçimliliği onların kontak lens ve etkin madde salım sistemi olarak kullanımının bir kanıtıdır. Bu çalışmada, suda çözünen ketorolak trometamin’in (KT) ve suda çözünmeyen indometazin’in (İND) poli (bütilmetakrilat) (pBMA), poli(2hidroksietil metakrilat) (pHEMA) ve poli(2-hidroksipropil metakrilat) (pHPMA) gibi hidrojeller ve plastizer olarak Polietilen glikol 300 (PEG) kullanılarak film hazırlama yöntemiyle insertleri hazırlanmıştır. Bu insertlerin şişme özellikleri tayin edilmiştir ve insetler Co-60 kullanılarak 1.2 Mrad doz ile ışınlanmıştır. Etkin madde salımı üzerinde bu parametrelerin etkisi incelenmiştir. Etkin madde salım mekanizması Korsmeyer ve Peppas tarafından geliştirilen yarı-emprik salım mekanızmasıyla tanımlanmıştır. Hidrojellerin şişmesi ve hidrojellerden etkin maddelerin salımı yan zincir büyüklüğü ile, akrilatın yan zinciri üzerinde hidroksil gruplarının yeralmasıyla ve formüllerde PEG 300’ün kullanılmasıyla hidrofilisitenin artmasından dolayı artmıştır. Suda çözünür KT ile suda çözünmeyen İND’den daha fazla salım görülmüştür. İnsertlerden etkin maddelerin salımı üzerinde sterilizasyon dozunun bir etkisinin olmadığı da gözlenmiştir. KT’nin salımı başlıca Fick difüzyon mekanizmasına uyum gösterirken, İND’in salımı onların n eksponent değerlerine göre başlıca Fick difüzyon mekanizmasına uymayam salım göstermiştir, Hydrogels are hydrophilic, three-dimensional networks which are able to imbibe large amounts of water or biolojical fluids, and thus resemble to a large extent biological tissue. The well-tolerated safety and biocompatability of Poly (2 – hydroxyethly methacrylate) and poly (2 -hydroxypropyl methacrylate ) hydrogels especially are evident in their use as contact lens and drug release system. In this study, inserts of water-soluble Ketorolac tromethamin (KT) and water- insoluble indomethacin (IND) were prepared using hydrogels such as Poly (butyl methacrylate) (pBMA), Poly (2-hydroxyethyl methacrylate) (pHEMA), and poly (2-hydroxypropyl methacrylate) (pHPMA), and a plasticizer such as Polyethylene glycol 300 (PEG) by film casting method. Swelling properties of these inserts was determined and they were irradiated with an absorbed dose of 1.2 Mrad by means of a Co- 60 source. The effects of these parameters on the drug release were examined. The mechanism of drug release was identified by means of the semi-empirical equation developed by Korsmeyer and Peppas. Swelling of the hydrogels and release of drugs from the hydrogels increased with size of side chain, hydroxyl groups on the side chain of the acrylate and using PEG 300 in the formulation, which increase hydrophilicity. Water–soluble KT showed higher release than water–insoluble IND. It was also observed no effect of irradiation dose on the release of drugs from the inserts. Release of KT mainly fit to the Fickian diffusion mechanism, whereas drug release of IND mainly showed the non-Fickian release mechanism according to their n exponent values

Bu çalışma farklı hidroksipropilmetilselüloz (HPMC) tiplerinin ve HPMC:doğrudan tabletleme ajanı (dta) oranının, tek tabakalı ve üç tabakalı matris tabletlerden Verapamil Hidroklorür`ün (VRP HCl) salımı üzerindeki etkilerine odaklanmıştır. İncelenen polimerler Methocel K100LV, K15M, K100M ve dta Ludipress® LCE`dir. Sekiz adet tek tabakalı ve dört adet üç tabakalı matris tablet doğrudan basım yöntemi kullanılarak hazırlanmıştır. Etkin madde salım çalışmaları USP XXVII`de yer alan uzatılmış salım yapan ilaç şekillerine ait makaleler prosedürüne uygun olarak yapılmıştır. HPMC tipi ve oranının etkin madde salımı üzerine etkili olduğu saptanmıştır. HPMC miktarı ve viskozluğundaki artışın, matrislerden etkin madde salımının yavaşlamasına neden olduğu tespit edilmiştir. İç ve dış tabakalarda düşük viskozluğa sahip HPMC içeren tabletler, farmakope limitlerine yakın veya limitler içinde salım profilleri vermişlerdir. USP XXVII kriterlerine uyan üç tabakalı matris tablet (F12) ve referans ürüne (Isoptin®-KKH) ait salım verileri matematiksel modeller (sıfır derece, birinci derece, Higuchi, Hixson-Crowell, Korsmeyer-Peppas), fark faktörü (f1) ve benzerlik faktörü (f2) kullanılarak değerlendirilmiştir. VRP HCl`in salım kinetikleri F12 için en iyi Higuchi modeline, Isoptin®-KKH için sıfır derece kinetik modeline uyum göstermiştir. F12 ve Isoptin®-KKH`ın her ikisi de n katsayılarına göre Anomali durumu göstermiştir. f1 (5.2) ve f2 ( 71.4) değerlerine göre F12 ile Isoptin®-KKH benzer kabul edilmiştir, This work has focused on the effects of different hydroxypropylmethylcellulose (HPMC) types and HPMC:direct tabletting agent (DC-agent) ratio on Verapamil Hydrochloride (VRP HCl) release from monolayered and three-layered matrix tablets. Investigated polymers were Methocel K100LV, K15M, K100M and DC-agent was Ludipress® LCE. Eight formulations were prepared as monolayered matrix tablets while four formulations were prepared as three-layered matrix tablets by direct compression method. Drug release studies were carried out according to the method given for Delayed Release Articles in USP XXVII. HPMC types and ratios were found to be effective on drug release. Increasing amount and viscosity grade of HPMC resulted in a decrease in release of drug from the matrices. Tablets containing low viscosity grade HPMC at inner and outer layers presented release profiles close to or within the limits of pharmacopeia. Release data of three-layered matrix tablet (F12) and the reference product (Isoptin®KKH) which were in agreement with USP XXVII criteria, were evaluated by mathematical models (zero order, first order, Higuchi, Hixson-Crowell, Korsmeyer-Peppas), difference factor (f1) and similarity factor (f2). The kinetics of VRP HCl release from F12 showed best fit to Higuchi model and Isoptin®-KKH well fitted to zero order kinetic model. F12 and Isoptin®-KKH were both show Anomalous transport mechanism according to their n exponent values. Depending on the results of f1 (5.2) and f2 (71.4) values, F12 and Isoptin®-KKH were found to be similar with regard to release kinetics

V ÖZET DOĞU AKDENİZ BÖLGESİ AKREP (SCORPIONES) FAUNASI KARATAŞ, Ayşegül Ege Üniversitesi Fen Bilimleri Enstitüsü Biyoloji Anabilim Dalı Danışman: Prof.Dr. Hüseyin Arıkan 2001, 93 sayfa Bu araştırma, Doğu Akdeniz Bölgesi'nde yayılış gösteren akrep türlerini belirlemek ve Türkiye Faunası'na katkıda bulunmak amacıyla yapılmıştır. Bu amaçla, söz konusu bölgeden toplam 271 akrep örneği incelenmiştir. Çalışmalar sonunda, Buthidae familyasından dört (Androctonus crassicauda, Mesobuthus eupeus, Mesobuthus gibbosus anatolicus, Leiurus quinquestriatus), Iuridae familyasından iki (Calchas nordmanni, Iurus asiaticus), Euscorpiidae familyasından iki {Euscorpius carpathicus, Euscorpius mingrelicus ciliciensis) ve Scorpionidae familyasından bir {Scorpio maurus fuscus) olmak üzere toplam yedi cinse ait dokuz tür ve alttürün bölgede dağılış gösterdiği tespit edilmiştir. Türkiye'de kayıtları bulunan 13 türden % 69.2'sinin bu alanda bulunuşuyla bölgenin tür sayısı bakımından oldukça zengin olduğu sonucuna varılmıştır. Bu türlerden M.eupeus, Anadolu'nun batı bölümünde; Iurus asiaticus Toroslar'ın kuzeyinden ve C.nordmanni, araştırma bölgesinde ilk kez tespit edilmiştir. Diğer türlerle ilgili yeni dağılım alanları bildirilmiştir. Ayrıca bulunan akrep türleri ile ilgili bazı biyo-ekolojik bilgiler verilmiştir.

VII SUMMARY FAUNA OF SCORPIONS (SCORPIONES) OF THE EASTERN MEDITERRANEAN REGION KARATAŞ, Ayşegül Ege University Graduate School of Natural and Applied Science Department of Biology Supervisor: Prof.Dr. Hüseyin Arıkan 2001, 93 pages This study was done in order to establish species of scorpions, which ranges in the Eastern Mediterranean Region and to contribute to Turkish fauna. By this reason, it was investigated that a total of 271 specimens of scorpions from the area. In conclusion of the studies, it was established inhabit in the region by nine species and subspecies belong to seven genera, which are four species of the family Buthidae (Androctonus crassicauda, Mesobuthus eupeus, Mesobuthus gibbosus anatolicus, Leiurus quinquestriatus), two species of both of each families Iuridae (Calchas nordmanni, Iurus asiaticus) and Euscorpiidae {Euscorpius carpathicus, Euscorpius mingrelicus ciliciensis), and also one species of the family Scorpionidae {Scorpio maurus fuscus). In conclusion, it is thought that the region is rich with respect to number of species, by 69.2 % of 12 species, which recorded in Turkey, were found in this area. Of these species, M.eupeus, Iurus asiaticus and C. nordmanni were found for the first time in the western part of Anatolia, north of the Taurus and the study area, respectively. New distributional localities for the other species were established. Additionally, some bio-ecological data about the species of scorpions were given.
