Background: Feline panleukopenia virus (FPV) is a widespread and highly infectious pathogen in cats with a high mortality rate. Although Yanji has a developed cat breeding industry, the variation of FPV locally is still unclear. Objectives: This study aimed to isolate and investigate the epidemiology of FPV in Yanji between 2021 and 2022. Methods: A strain of FPV was isolated from F81 cells. Cats suspected of FPV infection (n = 80) between 2021 and 2022 from Yanji were enrolled in this study. The capsid protein 2 (VP2) of FPV was amplified. It was cloned into the pMD-19T vector and transformed into a competent Escherichia coli strain. The positive colonies were analyzed via VP2 Sanger sequencing. A phylogenetic analysis based on a VP2 coding sequence was performed to identify the genetic relationships between the strains. Results: An FPV strain named YBYJ-1 was successfully isolated. The virus diameter was approximately 20-24 nm, 50% tissue culture infectious dose = 1 × 10^-4.94/mL, which caused cytopathic effect in F81 cells. The epidemiological survey from 2021 to 2022 showed that 27 of the 80 samples were FPV-positive. Additionally, three strains positive for CPV-2c were unexpectedly found. Phylogenetic analysis showed that most of the 27 FPV strains belonged to the same group, and no mutations were found in the critical amino acids. Conclusions: A local FPV strain named YBYJ-1 was successfully isolated. There was no critical mutation in FPV in Yanji, but some cases with CPV-2c infected cats were identified.

Five phase theory has significant effect on Traditional Chinese Medicine, which puts its emphasis on correlation and integrity. However, the five phase theory itself has a limitation that it cannot reflect the general correlation and special features of affairs. Traditional Chinese Medicine pertains the five organs to five elements, absorbing the essence of the five phase theory, and transcending the limitation of the five phase theory in practice. Therefore, Traditional Chinese Medicine and other traditional medicine theories can be called as "five viscera correlation theory". On the course of modernization of traditional medicine, the effects among the five viscera can be concluded to 3 correlations of promotion, coordination and inhibition, to illustrate the integrity and correlation theory of traditional medicine from different approaches.

한국어는 7,000만 우리 민족이 사용하는 언어로 세계의 많은 언어 가운데에서 사용인구로 볼 때 상위권에 속하며, 동아시아 지역의 사용 분포를 살펴보면 한반도와 중국 동북 3성으로 구분 할 수 있다. 지금까지 한국어와 중국 조선어의 비교 연구가 많이 진행되어 왔으나 객관적이고 과학적으로 어느 정도 차이가 있는지 알려져 있지 않다. 본 연구를 통하여 한국어와 중국 조선어의 대략적인 차이를 분석하고, 컴퓨터를 이용하여 한국어를 중국 조선어로 전환하며 지속적인 연구 분석을 위해 중국 조선어 기초 자료 구축 및 분석 시스템을 개발하고자 한다.

연변지역은 문화 역사적으로 한국뿐만 아니라 중국에 있어서도 관심 지역이다. 연변지역에 대한 문화 역사적 연구는 많지만 유적 지도화에 대한 연구는 찾아보기 힘들다. 본 연구에서는 구글어스 영상을 이용하여 연변지역의 문화 역사 유적을 지도화하고 공간적 특징을 분석하고자 하였다. 석기시대부터 청나라까지 시기별로 문화 역사 유적 분포도를 제작하였다. 지도화 기호체계는 사기별로 색상기호와 유형별 기호를 제작하였다. 지도화 결과 연변지역에는 다른 시기와 비교해 발해와 요 금나라의 유적이 많은 비중을 차지하였다. 특히 고구려, 발해, 요 금나라의 유적은 시 공간적 누층구조를 보였다. 분포특정은 초기에 분지지역과 하천지역에 위치해 있었고, 역사시기 이후에는 구릉과 산지지역으로 이동하였다. 연구결과는 문화 역사 유적 관련 후속연구에 정보를 제공해 줄 수 있을 것으로 기대된다.

The objective of this research was to determine the grain oil most suitable for the production of omega-3 fatty acids (FAs) in China, in order to supply dietary omega-3 FAs. This study focused on the nutritional significance of omega-3 FAs and the wide search of sources of dietary omega-3 FA from oil grains produced in China. Five oil grains produced in the Yanbian region, namely sesame, flax, peanut, soybean, and corn, were selected and analyzed for their fat content and FA composition. Results showed that the lipid content in sesame, flax, and peanut, which was more than 30%, was higher than that in soybean and corn. The polyunsaturated FA content was found to be directly proportional to omega-3 FA content. Flax showed a considerably higher omega-3 FA content (53.43%) than other samples, suggesting its potential as a source of dietary omega-3 FA. The optimal daily intake of flax for males and females was determined to be 2.99 g (over one table spoon) and 2.06 g (nearly one table spoon), respectively. Flax showed the lowest ratio of omega-6 and omega-3 FA (0.32%), which can help reduce this ratio in the human body; the intake of equal amounts of flax and corn could achieve an optimum ratio of 1:1. These results can prove to be valuable in the preparation of various functional dairy foods in the future.

The purpose of this study was to identify the perceptional patterns of Korean traditional food and to compare the preference and intake frequencies of daily traditional Korean food among the identified perceptional patterns in the Yuabian area. Data were collected from 261 Korean housewives in Yanbian and underwent cluster and group mean analysis. The results revealed two different patterns: tradition-oriented vs. modem-oriented. Descriptive statistics showed that perceptional patterns are likely to vary depending on socio-demographic background as well as the preference and intake frequencies of daily traditional food. Similarities and differences in these perceptional patterns, the preference and the intake frequencies of traditional daily food are discussed, and future implications for food nutritionists and Asia marketers are presented.

The present authors investigated intestinal parasitic infections among North Korean residents and refugees in China in 2003. The Kato-Katz method was applied to 236 residents and soldiers in a town on the North Korea-China border and to 46 people at a refugee camp in China. Only eggs of Ascaris and Trichuris were detected, with egg positive rates of 41.1 % and 37.6%, respectively. The total egg positive rate was 55.0% and most of those who were egg positive were only lightly infected. Women of 61.2% and men of 53.1 % were egg positive. The refugees from rural areas showed higher egg positive rates than those from urban areas. The present investigation confirmed high prevalence of soil-transmitted intestinal helminths in rural borderline areas of North Korea.

In this age of information, companies are losing grip of their image. Perhaps this explains the reason why corporate social responsibility (CSR) has become somewhat of a buzzword among established fashion industry leaders-companies seem determined to show stakeholders that they have values, are responsible, and they are driven by more by values than the prospects of financial gain. This study assessed the effect of CSR have in the fashion industry on the corporate image, product preference, and purchase intention in China. Three hundred native residents in China participated in an online survey from 1-12th Jan 2017. The results were as follows: (1) CSR consists of five components; economic responsibility, ethical responsibility, environmental protection, consumer protection, and philanthropic responsibility. (2) Both economic and ethical responsibilities have significant positive effects on corporate image, while perceived CSR does not have significant effect on product preference or purchase intention. (3) Consumers' product preference and perceptions regarding corporate image influence their intention on making a purchase. These findings might operationally assist Korean fashion corporations to identify and address the critical aspects of CSR management which will improve their image as good corporate citizens and foster favorable attitudes toward fashion products from China. Further results and direction of future research were discussed.
