To many contemporary western scholars who study the history of early Christianity or the Christianity history in Asia, ―Nestorian Church‖ is a wrong and misinterpreting title for the church developing in Persia for so long time. However, most Chinese scholars who pay attention to the topic of Christianity in Tang dynasty, one of the focal points of the field of medieval Sino-western cultural relationship, still base their studies on the inaccurate or completely wrong conceptions of the so-called ―Nestorian Church‖ which were formed almost one hundred years ago. It‘s so pity that they seem to have no interest on the new advancement of ―other‖ disciplines. I think it is quite necessary for the researchers of Christianity in Tang dynasty to learn and absorb the achievement of the study on history of western Christianity and probably some other discipline, because in contemporary context, the study of ―Nestorian Church‖ is no longer a pure philology study based merely on the excavated literature, it is some kind of synthetic culture study and religion study combining variety of knowledge. In this paper, I try to present and arouse the attention of the above mentioned problem according to analyse four wrong or misty statements being used to be followed by Chinese scholars, which could have been revised many years ago if referring to the achievement of other disciplines.

"Mainland China and Taiwan have both successfully undergone remarkable transitions from high to low fertility in recent decades. Comparing the transitions of the two Chinese populations brings out striking similarities in the changes in age patterns of fertility, but distinctive contrasts between the trends and speed of declines.... An overview of the history of population dynamics in the past 500 years reaffirms the assertion that fertility and mortality rates in ancient China were primarily reflections of biological responses to population pressure on resources. The results of the regression analysis of this study demonstrates that this density-dependent relationship has gradually vanished as the deliberate control of fertility prevails in contemporary China and Taiwan. The prevalence of fertility control is in large part attributable in Taiwan to the rational response of the population to changes in economic and social conditions that favor fewer children while the size of families in China is largely prescribed by the government there."

Urbanization trends in the Lower Yangtze region of China from 1500 to 1900 are examined. Data are from a variety of sources, including genealogies, local records, and other literature. An attempt is made to analyze the demographic characteristics of the urban population. "The demographic characteristics in respect to marriage, fertility and mortality found from the genealogies do reveal that there were dissimilarities between the rural and urban dwelling populations. Moreover, findings related to migration tend to support that rural to urban migration was an important factor that speeded up urbanization in the Lower Yangtze Region." (SUMMARY IN ENG), (excerpt)

The decline in mortality in Taiwan since World War II is analyzed using life tables. "Special features of the research include (1) a phase-of-life-specific, rather than an age-specific, analysis of mortality, and (2) the use of measures based upon person-years of life in phase intervals, rather than survival rates or expectation of life at given ages. The empirical results suggest that the mortality decline can be described as a two-stage process: an initial stage of substantial improvement in life expectancy between 1950 and 1965, and a final stage of slow gain in life expectancy since 1965." Age and sex variations in mortality and differing rates of mortality decline are noted. Implications of increased longevity for economic and social programs are also considered.

The plants of the Trigonostemon sp. genus(Euphorbiaceae family) comprising about 50 species worldwide are mainly distributed in tropical and subtropical Asia, 10 species of which can be found in southern of China. Phytochemical studies on the plants in the genus have demonstrated a large amount of terpenoids and alkaloids. Modern pharmacological studies have demonstrated cytotoxicity, antivirus, antibacterial, anti-inflammation and other pharmacological activities. In this paper, chemical compositions and biological activities of Trigonostemon genus at home and abroad over the past decade were summarized, in order to provide scientific basis for the further development and utilization of Trigonostemon plants.

Objective: To detect the chloroquine-resistant molecular marker polymorphisms in Plasmodium falciparum imported into China, investigate the mutation types of P. falciparum chloroquine resistant transporter ( Pfcrt ) gene at positions 72 to 76, and analyze the specificity of the P. falciparum specimens with different origins., Methods: A total of 674 filter paper blood samples were collected from the National Malaria Diagnosis Reference Laboratory of China in 2012 and 2018. The amino acid po- sitions 72 to 76 of the Pfcrt gene on chromosome 7 were amplified using nested PCR assay and sequenced, and the sequencing results of the target gene fragment and the geographical region-specific prevalence of the mutations in the Pfcrt gene were analyzed., Results: Among the 674 imported P. falciparum malaria cases in China in 2012 and 2018, 99.5% (644/674) were from Africa, which were predominantly from western and central Africa (80.4%, 518/644), and 4.5% (30/674) from Southeast Asia and Oceania (Papua New Guinea). A total of 4 site mutations (C72S, M74I, N75E and K76T) and 5 haplotypes (CVMNK, CVIET and SVMNT and two mixed types) were identified, with haplotypes CVMNK and CVIET present in parasites of both African and Southeast Asian origins, SVMNT detected in Southeast Asia (Myanmar) and Papua New Guinea isolates, the mixed type of haplo- types CVMNK/CVIET detected in P. falciparum of African and Southeast Asian origins, and the mixed type of haplotypes CVMNK/SVMNT detected only in the Myanmar isolate. Most P. falciparum parasites of the African origin carried the wild-type Pfcrt allele (77.7%, 478/615), and 68.0% (17/25) of the P. falciparum parasites of the Southeast Asian and Papua New Guinea or- igins harbored chloroquine resistant molecular markers ( χ 2 = 28.5, P < 0.05). The constituent ratio of the wild- and mutant-type Pfcrt allele varied in different geographical regions of Africa ( P < 0.01), and the lowest prevalence of the wild-type Pfcrt allele was seen in western Africa., Conclusions: Among the 674 imported malaria cases in China in 2012 and 2018, the P. falciparum imported from Sotheast Asia habors a higher proportion of resistance to chloroquine and a higher molecular polymophism at ami- no acid positions 72 to 76 of the Pfcrt gene than the parasite of the African origin.

Wolfberry has important unique medical values as well as edible and commerce values. In this paper,we analyze the characteristics and problems of international trade of wolfberry based on the customs data between 2008 and 2017. During periods of these ten years,the wolfberry was mainly exported with a small proportions of imports. The total export volume increased steadily,reached 82 182. 08 tons and 696. 622 million dollars respectively. Wolfberry came from 31 provinces/autonomous regions and exported to 105 countries and regions through 21 ports. Most of the total exports of wolfberry flew to markets of Asia and Europe,the Ningxia autonomous region was the major export province. Large amount of wolfberry exported through Tianjin port. Compared with the export volume,the import is almost negligible,mainly coming from North Korea,almost all through Changchun port,Jilin province to enter the domestic market. There is a situation of"import of domestic goods". To enhance the international competitiveness of wolf berry industry,we must rely on the fundamental research of wolfberry,speed up the standardization process,strengthen the scientific and technological innovation in wolfberry products,improve the added value and profit of wolfberry.

"This paper extends research on the difference in ageing factors between Taipei City and Taiwan's rural area in terms of the changes in fertility, mortality, and migration rates.... The analysis--based on data collected from 1968-1993 demographic data in Taiwan-Fukien Demographic Fact Book...provides strong evidence that population processes (fertility, mortality, and migration) have different influences on the population ageing of Tapei City and Taiwan's rural area."

"This paper studies the inter- and intra-provincial migration patterns, major streams, the demographic characteristics of migrants and their reasons based on the 1990 100% China census. Under the government efforts [to move] to a market economy, the household registration system gradually loses its function. The social and economic impacts of [the] significant size of floating population [in] cities are addressed." (SUMMARY IN ENG), (excerpt)

"Based on the cohort component projection, this paper simulates the effects of fertility compression on birth sequence and age composition in Taiwan, and explores the implications for social welfare. As a first step, we fix the fertility schedule on the age pattern of 1956 while leaving the TFR to shift as it was, [and] simulate the single year of age population groups from 1956 to 1992.... We subsequently assumed a fixed age pattern of fertility, a compressed pattern and an expanded pattern in a projection of five year...age groups from 1997 to 2097." (SUMMARY IN ENG), (excerpt)

"The purpose of the paper is to examine the nature and the structure of elderly women's dependency [in Taiwan] and the underlying socio-cultural-political forces. From the social constructive perspective, we focused on three constructive forces--the Chinese patriarchal/patrilocal family system, the gender role, and the state policy on elderly welfare. Three types of dependency--economic dependency, dependency for personal and health care, and living arrangement--were examined." (SUMMARY IN ENG), (excerpt)

"In this paper we employ family status life tables to assess the effects of demographic processes on family composition and to reveal trends in elderly living arrangements [in Taiwan]. We found that further declining fertility and changing nuptiality are responsible for the prevalence of nuclear family composition. [The] increasing proportion of nuclear families indicates a decreasing probability [of] elderly parents living with their married children. In addition, according to the current nuptiality trends, the increasing proportion of women of all ages who remain [unmarried] will strengthen its effects on family composition in the near future."

"This paper applies the multiple-decrement life table to the analysis of mortality and self-reported disability [for Taiwan], annually from 1986 until 1989.... It was found that during this period of time, the shifts in 'mortality' and 'disability' curves conform to the compression hypothesis. The area in between the two curves [has] shrunk in the 4 year period.... The sex differential in disability has been examined. It is concluded that though at the younger ages women tend to spend less person-years in disability, the situation is quite different at older ages. Women tend to have greater chance [of] and longer duration suffering from disability at old age than men." (SUMMARY IN ENG), (excerpt)

"This paper [tests] both Clark's negative exponential model and Newling's quadratic exponential model [using data for] population densities in districts of Kaohsiung Metropolis [Taiwan]. It proposes four theoretical amendments and supplements to the population density function and the related theories." (SUMMARY IN ENG), (excerpt)

"In this paper, we will focus on [population growth, birth, and marriage rates in Taiwan] and explore [them] in terms of the time series model. Furthermore, the comparison and analysis will be made utilizing [the] univariate ARIMA model, transfer function model and multivariate ARIMA model accordingly. The seasonal factor will also be considered. Lastly, [projections] will be made on the short term growth rate of these three indexes, and we will also estimate the monthly sum of population of the next two years in Taiwan."

The author discusses urbanization in the People's Republic of China and problems in data analysis "due to the lack of standardized and well-defined terms for the urban settlements and urban population on the mainland. This paper clarifies the relationship between geographic units and demographic data, identifies the major types of urban population and their characteristics, explains the reasons for the differing levels of urbanization revealed in various data sources, and presents a comprehensive data series on mainland China's urbanization that best approximates reality."

The quality of children has mostly been discussed in so far as it can affect fertility. The sex of children is a particularly important subject in this context. Because a child's sex is stochastically determined, Ben-Porath and Welch used the household production approach to identify risky decision points. The purpose of this paper is twofold. One is to simplify Ben-Porath's and Welch's model. The other is to use KAP data in Taiwan to examine the causes of preferring to have at least 1 boy and to test in what direction and the degree to which such preferences affect fertility. The results can be summarized as follows: 1) preferring to have at least 1 boy is significant in Taiwan; 2) the data support both the assumption of inelastic demand and mild learning; 3) concerning the dummy variable for the existence of at least 1 boy preference, it can be shown that the regression coefficients for each of family structure, wife's education, and husband's occupation were statistically significant at the .01 significance level; and 4) when the impact of "at least 1 boy preference" on completed family size is concerned, the regression coefficient for the existence of at least 1 boy preference is positive as expected and also the most significant variable included.
