本文指出，現行通訊保障及監察法（通保法）於立法之初係以中央系統通訊傳輸作為制度設計之前提，導致其在本質上難以對應分散系統通訊傳輸之規制需求。而網路傳輸即分散系統之典型例，故本文以有網路封包補食器之稱的食肉獸系統（進行通訊監察之一種科技手段）作為主要檢討素材，藉以釐清問題之所在。再以此為前提，聚焦於數位匯流之技術性特徵，改從跨巨庫觀點為進一步的綜合分析。所謂跨巨庫，係指以數位匯流技術為代表的各類情報通訊科學技術，搭配上各式各樣的感知器或探測器乃至於各種端末，而得讓各類不同的資料庫具有可跨虛擬與實境之無限連結可能性，藉此生成一個可不斷有機成長的跨領域之巨大資料庫。政府利用此一既存的跨巨庫現象來進行偵查時，可區分為四階段，即A設備裝置階段、B取得資訊階段、C儲存累積階段、D照合分析階段，此即所謂跨巨庫觀點。本文擬由此觀點進一步深入剖析，並提出所謂水平式分階段規制論（即區分上述A、B、C、D各階段分別進行不同的規制），最後以之為據，針對現行通保法提出具體之修法建言。 This article points out that the current Communication Security and Surveillance Act (CSSA) was originally based on a centralized system as its prerequisite for legislation, so it is essentially unable to cope with the problems of decentralized systems. Because the Internet is a typical example of a decentralized system, this paper takes the Carnivore System (a technological method for internet surveillance) known as a packet sniffer as the main material to clarify the problem. With this as the premise, this article focuses on the technical characteristics of digital convergence, and change it from the perspective of “the across-giant-database” to further comprehensive analysis. With the development and popularization of information technology and various sensors, everyday life in the modern world is often inseparable from a variety of giant databases that have unlimited possibility of connecting the virtual and the real world. This is the aforementioned “the across-giant database”. “The across-giant-database” as an investigative method can be divided into four stages: A stage-equipment installation, B stage-getting information, C stage-storage accumulation, and D stage-conformity analysis. This is the so-called cross-big library view. This article further analyzes this point of view and puts forward the so-called horizontal phased regulation theory to make specific suggestions for amending the current law.

根據相關統計資料顯示，各國電子煙的盛行率逐年攀高，尤其青少年使用電子煙的平均盛行率已達16.4%。衛生福利部國民健康署（2021）推估我國青少年使用電子煙已超過5.7萬人，對青少年健康之危害甚大。為了能淨化校園，杜絕電子煙對青少年的戕害，發展電子煙防制措施已是刻不容緩。本研究採「前導試驗」方式，以某所國小為場域進行實務教學，旨在瞭解透過本教學方式是否能提升教學成效。收案時間為2021年3月至4月，由場域學校之教師執行本研究的實務教學活動，執行期間共計53人於教學前後完成問卷施測，結果發現在知識、自我效能等變項能有正向的提升效果，顯示本研究設計之教學活動具可行性，可作為校園電子煙危害防制的實務措施。 Aim and Motivation of the Study Additives in electronic cigarettes (e-cigarettes) can damage the autonomous nervous, central nervous, cardiovascular, and digestive systems. Furthermore, these additives may contain cannabis, amphetamine, and other drugs. Therefore, e-cigarettes can be a route through which additive substances enter the body and cause physical and mental harm. Studies have indicated that the progression to future smoking in nonsmoking adolescents increased six-fold after e-cigarette use. A 2018 study revealed that the mean prevalence of e-cigarette use among adolescents in nine countries was 16.4%. The prevalence of e-cigarette use among adolescents in Taiwan is gradually increasing; in March 2021, nearly 60,000 Taiwanese adolescents used e-cigarettes, which illustrates the popularity of e-cigarette use in Taiwanese youth. Therefore, increasing adolescents’ caution toward e-cigarettes and preventing e-cigarettes from harming schools have become urgent concerns in health education. Literature Review In 2020, Liu, Gaiha, and Halpern-Felsher investigated methods for controlling e-cigarette use by examining 16 e-cigarette prevention and cessation or treatment programs. Of these programs, few were related to e-cigarette intervention. However, seven studies have evaluated the cognitive effectiveness of e-cigarette control programs. Two studies were conducted in 2021: that of Gaiha et al. referenced the Stanford Tobacco Prevention Toolkit to develop a 30-minute e-cigarette prevention educational activity and that of Weser et al. employed virtual reality to design an e-cigarette prevention activity called “Invite Only VR: A Vaping Prevention Game” (Invite Only VR). In the first study, researchers were able to increase junior and senior high school students’ e-cigarette awareness and decrease the students’ behavioral intention to try e-cigarettes. The second study demonstrated that moderate knowledge and perceived harm in junior high school students led to a decrease in reported likelihood of using e-cigarettes; however, no significant changes in attitudes, social perceptions, and self-efficacy were observed. Existing e-cigarette prevention and control programs lack comprehensive designs. Therefore, more evidence-based tools, resources, and related evaluation studies are required. Study Methods In this pilot study, students from a grade 5 and a grade 6 class were included as participants. Teachers combined a “smoke-free adolescence” teaching activity focused on controlling e-cigarette use with actual school classes to guide students through experiential classes. This enabled teachers to adjust the design of the teaching activities as required. A structured questionnaire was used in this study for pretest and posttest effectiveness evaluations of knowledge, attitudes, self-efficacy, and intention. SPSS 22.0 was used to perform a paired t test to compare differences in participants before and after course activities. Study Results A total of 53 elementary school students completed the questionnaire. A paired t test was used to assess the performance of the students with respect to knowledge, attitudes, self-efficacy, and intention. The results revealed no significant differences in levels of knowledge and self-efficacy. However, the mean values for both attitudes and intention were higher in the posttest than in the pretest, which indicates that teaching intervention to prevent e-cigarette harm can positively affect attitudes and intentions. Discussion and Suggestions Conventional health education in Taiwan provides health theme–related factual knowledge but lacks scenario-based guidance and integration. This causes student knowledge to be singular or fragmented and is not conducive to cultivating health literacy among students. The “smoke-free adolescence” school teaching activity use employed in this study was developed with consideration for individuals, families, schools, and the law, and various teaching materials were designed that combined the 4Fs (facts, feelings, findings, and future) and health literacy. These materials included scenarios and were presented in digital, comic, and animation formats, which have broad and flexible applications. The questionnaire included items measuring knowledge, attitudes, self-efficacy, and intention to not use e-cigarettes. The results of the evaluations support the usability of the course. The proposed course can be implemented in the future, and suitable themes can be selected according to on-site teaching contexts and subsequently evaluated for effectiveness. In this pilot study, only one elementary school served as the study site, and convenience sampling was employed. Thus, the study is limited in its generalizability. We recommend that the sampling scope and size be increased in future studies and that random sampling be employed to improve sample representativeness. In addition, this was only a preliminary study. No control group was included for comparison, and student follow-up was not performed. Therefore, we were unable to elucidate the long-term effectiveness of the teaching materials; future studies can consider this aspect.

Objective To observe the clinical effect of traditional Chinese medicine nursing combined with comprehensive rehabilitation training and routine rehabilitation nursing on children with mental retarda- tion by moxibustion with aconite. Methods A total of 120 children with mental retardation diagnosed in the outpatient department or in the hospital from February to December, 2022 were selected and divided into the observation group and the control group, with 60 cases in each group. The control group was given comprehensive rehabilitation training and routine rehabilitation nursing, while the observation group was given tradition- al Chinese medicine nursing on Baihui point with aconite moxibustion on the basis of the control group. To observe the changes of development quotient(DQ) of each energy area of Gesell Intelligence Development Diagnostic Scale(GDS) and the scores of children's comprehensive function evaluation scale before and after treatment, as well as the clinical efficacy. Results After treatment, the DQ of each energy area of GDS was improved in both groups. The scores of adaptive behavior, large exercise, fine movements, language and personal- social behavior in the observation group were(67.92±11.69),(61.88±13.20),(63.50±13.20),(57.35± 11.91),(57.87±11.89) points respectively. All the scores were higher than those of the control group (46.70±18.15),(49.85±17.78),(48.25±16.69),(37.78±13.46),(42.35±14.20) points, and the differences were statistically significant (P<0.05). The scores of all items in the children's comprehensive function evaluation table had been improved. The scores of cognitive function, speech function, sports ability, self-care action and social adaptation in the observation group were (10.98±3.61), (12.12±4.08),(18.81±5.42), (11.83±6.03),(8,87±3.14) points respectively. All the scores were higher than those of the control group (5.29±1.65),(6,58±3.20),(15.30±5.42), (5.11±4.09), (6.11±1.79) points, and the differences were statistically significant (P<0.05). The total effective rate of GDS in the observation group [91.7%(55/60)] was higher than that in the control group [76.7%(46/60)],and the total effective rate of children's comprehensive function evaluation [93.3%(56/60)] was also better than that in the control group [80.0%(48/60)], with statistical significance (P<0.05). Conclusion Moxibustion of Baihui point with aconite root combined with comprehensive rehabilitation training and routine rehabilitation nursing is effective in treating mental retardation.

To explore the influencing factors of distal portal vein thrombosis and its effect on prognosis in patients with cirrhotic portal hypertension after transjugular intrahepatic portosystemic shunt (TIPS). 300 patients with cirrhotic portal hypertension who underwent TIPS in Nanfang Hospital of Southern Medical University from January 2021 to January 2023 were selected, patients were divided into thrombosis group and non-thrombosis group according to the occurrence of distal thrombosis of portal vein branches within 6 months after operation. Compared the clinical data of two groups, the related factors of distal portal vein thrombosis after TIPS were analyzed by Multivariate Logistic regression.The prognosis in two groups at 6 months after operation was compared. The incidence of distal portal vein thrombosis was 10.67% (32/300) after operation. There were statistically significant differences in the proportion of age, plasma D-dimer (D-D), total cholesterol (TC), low density lipoprotein (LDL) levels within 3 days before operation, main portal vein diameter, left portal vein diameter, Child-Pugh grade A ratio, portal vein flow rate between thrombosis group and non-thrombosis group (P<0.05). Multivariate Logistic regression analysis showed that advanced age, elevated LDL levels, and increased diameter of the left portal vein diameter were risk factors for distal portal vein thrombosis after TIPS, while Child Pugh grade A was protective factor (P<0.05). There was no significant difference in TIPS stent patency rate, hepatic encephalopathy, liver function injury and mortality rate between thrombosis group and non-thrombosis group at 6 months after TIPS (P>0.05). The distal portal vein thrombosis after TIPS in cirrhotic portal hypertension is related to age, preoperative LDL, Child-Pugh classification and diameter of left portal vein, but has no effect on the 6-month postoperative TIPS stent patency rate, hepatic encephalopathy, liver function injury, and mortality rate in patients.

[Objective] The aims of this study are to study the effects of climate factors on soil organic carbon components, carbon, nitrogen and phosphorus contents and their stoichiometric ratios in the early stage of artificial slope restoration, to reveal the effects of climate factors on soil organic carbon components, carbon, nitrogen and phosphorus contents and their stoichiometric ratios in the early stage of artificial slope restoration, and to provide guidance and suggestions for the maintenance of artificial slope restoration in the later stage and ensure the positive succession of artificial slope restoration. [Methods] Slope soil samples artificially repaired by vegetated concrete with the same initial base material preparation and similar plant preparation were collected from Zhanjiang, Wuzhou, Yichang, Nanyang, Jiaozuo, Weifang and Jiacha. Data of organic carbon components, carbon, nitrogen and phosphorus of soil samples were obtained through determination. Redundancy analysis was adopted. The effects of climate factors on soil organic carbon component, carbon, nitrogen and phosphorus content and stoichiometric ratio in the early stage of slope restoration were studied. [Results] The F1 content of artificial repaired slope varied from 1.10 to 3.64 g/kg at the initial stage of succession. The variation range of F2 content was 1.33 ～ 3.04 g/kg. The content of F3 varied from 2.02 to 3.34 g/kg. The content of F4 ranged from 10.86 to 15.24 g/kg. TOC content ranged from 15.52 to 24.71 g/kg. TN content ranged from 0.61 to 0.93 g/kg. TP content ranged from 0.81 to 1.22 g/kg. C∶N ranged from 23.55 to 27.95. C∶P ranged from 17.26 to 23.09. N∶P ranged from 0.72 to 0.98. C∶N∶P ranged from 17.26∶0.75∶1 to 24.81∶0.95∶1. [Conclusion] In the early stage of the artificial restoration slope, carbon and phosphorus are medium and above, and nitrogen is insufficient. The organic carbon component is mainly inert organic carbon and the organic carbon has strong stability. The main influencing factors on organic carbon components were mean annual temperature, species richness and mean annual precipitation. The main factors affecting soil carbon, nitrogen and phosphorus contents and their stoichiometric ratios were annual mean temperature, species richness, pH and bulk density. [ABSTRACT FROM AUTHOR]

Objective To investigate the expression and regulatory mechanism of PTPN2 in psoriasis, and to analyze the effects of PTPN2 on psoriasis related immunity in order to determine whether PTPN2 can be used as a potential therapeutic target for psoriasis・ Methods R language (3. 6. 3 version) was used to determine the difference in expression levels of PTPN2 between psoriatic patients and controls, and the receiver operating characteristic (ROC) curve of PTPN2・ The Gene Enrichment Analysis software (GSEA) and the Protein Interaction Analysis Database (STRING) were used to determine enrichment pathway of PTPN2 in the psoriasis dataset, and the interaction network of PTPN2 co-expressed genes・ The distribution and expression of immune cells in psoriasis datasets were analyzed w让h CIBERSORT software・ The differential expression of immune response pathways and immune response gene sets in psoriasis and their correlation with PT-PN2 were analyzed using R language (version 3. 6. 3). Results PTPN2 mRNA was highly expressed in psoriatic lesions. Immune infiltrating cells, immune response pathways, and immune response gene sets were abnormal in psoriatic lesions.

In order to accurately and rapidly determine the content of gold, silver, platinum, and palladium in crude selenium, a method for the determination of gold, silver, platinum, and palladium in crude selenium by oxidation roasting and lead assay combined with inductively coupled plasma atomic emission spectrometry (ICP-AES) was established. In the experiment, silicon dioxide was used to lay the bottom. The sample was heated up to 600 °C in stages and roasted for 2 h, the effect of removing selenium was fairly good, without losing gold, silver, platinum, and palladium; when the sample was 10.0 g and the silicon acidity in fire assay was 1.0, the fluidity of molten slag was good. Smooth and round precious metal granules can be obtained. Silver was precipitated and separated by hydrochloric acid after the precious metal particles were dissolved in nitric acid. Pt 265.945 nm and Pd 340.458 nm were selected as the determination lines of ICP-AES. The linear correlation coefficients of platinum and palladium calibration curves were all more than 0.999. The detection limits of platinum and palladium were 0.002 0 mg/L and 0.001 8 mg/L, and the detection limits were 0.006 7 mg/L and 0.006 1 mg/L, respectively. The relative standard deviation (RSD, n =7) of the results was 0.47% -5.9%, and the spike recovery rate was 97.3% 103.0%. The accuracy and precision met the requirements of production control.

Exploring the changes in the bacterial community and its influencing factors in the rhizosphere soil of late blight- affected potatoes under heavy metal stress in a geologically high background area is crucial to guarantee the safety of potato production. Rhizosphere soil samples were collected from both healthy and late blight-diseased potato plants ('Qingshu 9', 'Weiyu 5' and 'Weiyu 3'). Subsequently, the soil pH, organic matter content and heavy metal concentrations were analyzed. The bacterial community was analyzed using Illumina MiSeq high-throughput sequencing, while the heavy metal content in the potato tubers was determined simultaneously. In the soil of the tested area, the mean concentrations of Cd, Cr and Zn were 2.14, 170 and 220 mg/kg, respectively. Cd levels exceeded the risk control threshold of the national soil quality standard, while Cr and Zn levels exceeded the screening values. Among the potato tuber samples, only one exhibited a Cd concentration of 0.103 mg/kg, exceeding the national food safety limit standard. The predominant bacterial phyla and their relative abundances in the rhizosphere soil of diseased potatoes were Proteobacteria (33.16%-39.09% ) and Actinobacteria (13.45%-17.11% ); the predominant bacteria were primarily Sphingomonas (8.78%-12.30% ) and Gemmatimonas (6.22%-7.61% ). The relative abundance of dominant bacteria differed in diseased plants compared to healthy plants, with variations observed among different plant varieties in terms of bacterial diversity and abundance. After potato late blight infection, there was an increase in the diversity of the bacterial community in the rhizosphere soil, while the abundance of the bacterial community decreased. Principal component analysis revealed that the contribution rate of bacterial community differences between diseased plants and healthy plants was 29.59%. The results of redundancy analysis indicated that soil heavy metals and pH had a significant impact on the composition and structure of the soil bacterial community, particularly on the dominant bacteria. The differences in the bacterial community between healthy and diseased plants were more influenced by soil stress from Pb and Cr. Therefore, potatoes could achieve safe production even under heavy metal stress in high geological background areas. In the rhizosphere soil of infected potato plants, the diversity of the bacterial community decreased while the richness increased. The occurrence and development of late blight were affected by soil Pb and Cr through alterations in the beneficial bacteria within the rhizosphere soil bacterial community. [ABSTRACT FROM AUTHOR]

[Result] 83 volatile flavor compounds were identified from salted Apostichopus japonicas, mainly aldehydes, ketones, alcohols and esters. However, the relative content of characteristic volatile substances in different regions was different. Heptanal, octanal and other 13 aldehydes were common components of salted Apostichopus japonicas. Alcohols and ketones were the characteristic flavor substances of salted Apostichopus japonicas from Changdao, esters were the main flavor substances of salted Apostichopus japonicas from Weihai and Dongying, and no certain flavor ingredients were identified in the characteristic area of salted Apostichopus japonicas from Dalian. [Conclusion] The salted Apostichopus japonicas from different origins has unique flavor characteristics due to the different characteristic flavor substances, which can provide more reference for consumers to choose.

The study aims to clarify the potential mechanism of quercetin in the treatment of depression based on network pharmacology and molecular docking techniques. The corresponding protein targets of quercetin were screened from SwissTargetPrediction and Superpred databases; The genes associated with depression were screened out from OMIM and Genecards. Then, the Cytoscape3.9.1 software package was used to construct the PPI network and screen the hub gene;the DAVID platform was used to conduct Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. Finally, molecular docking methods was used for accuracy check. There are 103 nodes and 536 edges in the PPI network, in which SRC, MTOR, EGFR, AKT1, and PTK2 have the highest degree value. GO and KEGG analysis show that the protective effect of quercetin on depression mainly involves the negative regulation of apoptosis, signal transduction, protein phosphorylation, and other biological processes. The signal pathways mainly include HIF-1, ErbB, phospholipase D, and neurotrophin signal transduction etc. Molecular docking confirm the high affinity between quercetin and its targets (SRC, AKT1, MTOR) ． And these targets are enriched in the KEGG pathway. This study reveals the potential targets and the molecular mechanism of quercetin in the treatment of depression, in order to develop new drugs for depression. [ABSTRACT FROM AUTHOR]
