본 연구에서는 연변 지역간 유아교육여건의 현황을 분석하고 정책적 시사점을 제기하였다. 분석변수로는 기관수, 학급당 유아수, 정교사당 유아수, 정교사비율, 유아당 사용면적수, 유아당 도서량을 사용하였고 가장 간단한 불평등 측정지수인 범위와 표준편차를 사용하여 연변의 지역간 현황을 분석하였다. 2011년, 2012년, 2013년의 통계자료를 활용하여 분석한 결과, 연변 지역간 유아교육여건은 분석변수와 측정지표에 따라 다양한 양상을 보였으나, 전반적으로는 개선되고 있다. 그러나 일부 지표에서는 지역간 격차가 심화되고 있고 결론에서는 분석결과를 바탕으로 유아교육의 기회균등을 제고하기 위한 정책적 제언을 제시하였다.

The hepatoprotective effects of chalcone derivatives were evaluated in D-galactosamine/lipopolysaccharide (D-GaIN/LPS)-induced fulminant hepatic failure in mouse. Thirteen chalcone derivatives were synthesized for study and their hepatoprotective effects were evaluated by assessing aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels in serum. Chalcone preparations were injected into mice at 12 hand 1 h before intraperitoneal injection of D-GaIN/LPS. After abdominal administration, changes in AST and ALT between the control and treated groups were observed. Ten of the synthesized chalcone derivatives exhibited inhibitory effects on D-GaIN/LPS-induced levels of AST and ALT in mice. Compounds 2, 3, 8, 9, and 12 markedly reduced serum AST and ALT at 8 h, inhibited hepatocyte necrosis and showed significant hepatoprotective activities. The activity of compound 3 was compared with the bifendate (DDB) through oral administration. Compound 3 showed much higher inhibitory effects than bifendate for decreasing AST and ALT activity. The results indicate that compound 3 has strong hepatoprotective activity through suppression of tumor necrosis factor­alpha (TNF-alpha) preduction, reduction of the histological change in the liver, and attenuated of hepatocyte apoptosis confirmed by DNA fragmentation assay.

Purpose: The purpose of this study was to describe technological development, caring attributes and professional self-concept as perceived by nurses in YanBian. Method: Data were collected using an instrument containing 137 Likert items was administered to 477 RN's working in general hospitals in YanBian. The instrument contained sections which examined technological influences questionnaire(TIQ), caring attributes questionnaire(CAQ), and professional self-concept nursing inventory(PSCNI). Result: Descriptive and inferential statistics revealed by marital status and position. Married, working special ward nurses reported a higher TIQ score than that of unmarried and working general ward and OPD. PSCNI and CAQ score of head or supervisor nurses were higher than that of staff nurses. Subjects revealed very low score of CAQ, while PSCNI score was higher than that of other Asian countries such as Korea, Beijing China, HongKong China and Japan as proved in former study. Conclusion: Useful information for educators and nurse administrators is provided from this results. Further study needs to be done to discuss in the light of cultural and environmental differences between YanBian(Korean-Chinese) and Korean nurses.

Background: Optimal treatment for prostate cancer remains a challenge worldwide. Recently, T cell immunoglobulin mucin-3 (TIM-3) has been implicated in tumor biology but its contribution prostate cancer remains unclear. The aim of this study was to investigate the role of TIM-3 as a prognostic marker in patients with prostate cancer. Methods: TIM-3 protein expression was determined by immunohistochemistry and Western blotting in 137 prostate cancer tumor samples and paired adjacent benign tissue. We also performed cell proliferation assays using 3-(4,5-dimethylthiazol-2yl)-2,5-diphenyl- 2H tetrazolium bromide (MTT) and cell invasion assays. The effects of small interfering RNA (siRNA)-mediated knockdown of TIM-3 (TIM-3 siRNA) in two human prostate cancer cell lines were also evaluated. Results: TIM-3 expression was higher in prostate cancer tissue than in the adjacent benign tissue (P<0.001). High TIM-3 expression was an independent predictor of both recurrence-free survival and progression-free survival. TIM-3 protein was expressed in both prostate cancer cell lines and knockdown suppressed their proliferation and invasion capacity. Conclusions: TIM-3 expression is associated with a poor prognosis in prostate cancer. Taken together, our resutlts indicate that TIM-3 is a potential prognostic marker in prostate cancer.

The current and ethnic issues represented in child-rearing practices of Korean-Chinese families in YanBian, China, were studied with the participation of 7 primary caregivers (4 mothers and 3 grandmothers) of young children who were interviewed and observed in their homes. Current issues were categorized as competitive bilingual ability, expectations about third language learning (English), expectations of high academic accomplishment and early education, and economic challenges in parenting. Ethnicity issues included ethnic pride as Korean-Chinese, conflicts of ethnic education, participation in local Korean culture, and rearing the child to have the self-expressive and assertive characteristics of typical Korean children. Results were discussed in terms of understanding and supporting child-rearing of minorities and families with multi-cultural background.

Five isoflavones were isolated from the root of Caragana microphylla Lam. and the structures have been identified by means of chemical and physical methods. The isoflavones are 7-hydroxy-4'-methoxyisoflavone(formononetin), $form ononetin-7-O-{\beta}-glucoside(ononin)$, 7-hydroxy-3', 4'-methylenedioxyisoflavone(pseudobaptigenin), $7-O-{\beta}-glucuopyranosyloxy-3'- hydroxy-4'-methoxyisoflavone(calycosin-7-O-{\beta}-gluc-oside)$ and maackiain.

A quadratic B-spline finite element method for the spatial variable combined with a Newton method for the time variable is proposed to approximate a solution of Benjamin-Bona-Mahony-Burgers (BBMB) equation. Two examples were considered to show the efficiency of the proposed scheme. The numerical solutions obtained for various viscosity were compared with the exact solutions. The numerical results show that the scheme is efficient and feasible.

This study was designed to explore fundamental bases of parental role satisfaction and child-rearing practices by comparing Korean and Yanbian Korean-Chinese mothers who share the same cultural roots but live in societies with different ideology and values. Total of 314 mothers with children aged from three to six years participated in this study:- 160 Korean mothers from two cities in Korea and 154 Korean-Chinese mothers from two cities at YanBian in China. Parental Satisfaction Questionnaires by Hyun (1994) and Child Rearing Practice Measures developed by the researchers were used to measure mothers parental role satisfaction and child rearing practices. The results showed that Korean-Chinese mothers seemed to be more satisfied with their roles as parents than Korean mothers. Additional analyses with socio-economic variables reported that both Korean and Korean-Chinese mothers satisfaction about spousal support were higher and their role conflicts were reduced when the household income was higher. Interestingly, most Korean-Chinese mothers reported to be highly satisfied with spousal support whereas only highly educated Korean mothers seemed to be satisfied with spousal support. In addition, for child-related variables, Korean and Korean-Chinese mothers' parental satisfaction were not affected by their childrens gender or age but when they thought their childrens temperament was difficult, their role-conflict tended to increase.

본 논문의 목적은 중국 연변조선족자치주 延吉市 鄕鎭企業의 입지특성과 존립기반을 밝히는데웠다. 중국의 향진기업은 1970년대 후반 이후 중국의 급속한 경제성장을 주도하였을 뿐만 아니라 만성적인 농촌잉여 노동력 문제의 완화와 도시.농촌간의 사회.경제적 격차 완화에도 크게 기여하였다. 연변조선족자치주의 향진기업은 1980년대 말 이후 도시 인접지역과 중심도시와의 접근성이 양호한 지역을 중심으로 급격히 성장하였다. 이러한 입지특성은 단순한 시장에 대한 접근성 보다는 지역 내에서 해결하기 어려운 자금, 기술 및 판매상의 문제점을 도시기업과의 연합관계를 통해 해결하는 경영특성을 반영한다. 그리고 도시의 대규모 기업과의 경정에 있어서의 취약성을 지역내 풍부하고 저임금의 農民工 노동력 중심의 국지적 노동시장을 통해 극복하고 있다. 반면에 향진 정부의 역할은 초기단계에는 기업의 발달에 긍정적으로 작용하였으나 그 이후에는 오히려 기업경영의 자율성을 제약하는 이중적 성격을 가진다. 앞으로 자본주의 경제체제로의 전환을 전제로 한 경쟁력 강좌를 위해서는 기업경영의 자율성을 최대한 보장하는 제도개편이 요구된다.
