중국경제의 비약적인 발전과 더불어 지역 간 소득격차 문제는 더 이상 간과할 수 없는 사회적인 문제로 대두되고 있다. 따라서 본 연구는 중국의 동 중 서 3대 지역 도농 간 주민소득 격차의 현주소를 살펴보고 이와 같은 구조가 형성된 원인을 실증분석 하였다. 분석 결과 경제발전 정도가 상이한 3대 지역의 주민소득에 영향 주는 요인이 각자 다른 것으로 나타났다. 동부지역의 경우 정부의 교육지원 요인이 지역 내 도농 간 소득격차를 가장 효과적으로 완화시켜 주고 있는 것으로 나타났으며 특히 최근에 그 영향 정도가 점차 뚜렷해지는 추세를 보이고 있다. 그리고 중부지역의 경우 공업화 요인이 도농 간 소득격차를 효과적으로 완화시키고, 서부지역의 경우 정부의 농업생산지원 요인이 도농 간 소득격차를 효과적으로 완화시켜 주고 있는 것으로 나타났다. 따라서 중국 각 지역의 도농 간 소득격차 문제를 해소함에 있어 중국 전역에서 도사와 농촌을 모두 아우르는 통합적인 의료보험정책이나 사회복지정책 등을 추진시키는 것도 중요하지만 동부지역 지방정부의 교육비 지원 증가, 중부지역 지방정부의 공업추진특별정책, 서부지역 지방정부의 농업생산지원 증가 등 지역적 정책조치도 시급하다는 결론을 얻었다.

Objective: The objective of this experiment was to investigate the effect of dietary glucose oxidase (GOD), catalase (CAT), or both supplementation on reproductive performance, oxidative stress, and apoptosis in sows. Methods: A total of 104 multiparous sows were randomly assigned to four groups (n = 26) with each group given a basal diet, basal diet plus GOD at 60 U/kg, basal diet plus CAT at 75 U/kg, and basal diet plus GOD at 60 U/kg and CAT at 75 U/kg. Sows were fed the experimental diets throughout gestation and lactation. Results: Dietary GOD supplementation increased average daily feed intake of sows and litter weight at weaning (p<0.05). Dietary CAT supplementation reduced the duration of parturition, stillbirth, and piglet mortality and increased growth performance of weaned piglets (p<0.05). Dietary GOD and CAT supplementation enhanced antioxidant enzyme activities and lessened oxidative stress product levels in plasma of sows and elevated antioxidant capacity of 14-day milk and plasma in weaned piglets (p<0.05). Dietary GOD supplementation increased fecal Lactobacillus counts and reduced Escherichia coli counts of sows (p<0.05). Compared with the basal diet, the GOD diet reduced fecal Escherichia coli counts of sows, but the addition of CAT did not reduce Escherichia coli counts in the GOD diet. Dietary GOD and CAT supplementation reduced the apoptosis rate of the liver, endometrium, and ovarian granulosa cells in sows (p<0.05). In the liver, uterus, and ovary of sows, the mRNA expression of caspase-3 and caspase-9 was downregulated by dietary GOD and CAT supplementation (p<0.05). Conclusion: Dietary GOD and CAT supplementation could improve the antioxidant capacity of sows and weaned piglets, and alleviate hepatic, ovarian and uterine apoptosis by weakening apoptosis-related gene expression. Glucose oxidase regulated fecal microflora of sows, but supplementation of CAT to GOD could weaken the inhibitory effect of GOD on fecal Escherichia coli.

The inconvenient truth of sustainable public squat toilet culture varies among nationalities. This culture may be comfortable to the people of China, yet uncomfortable to the non-Chinese, according to the adequate environmental management in Yanbian Korean Autonomous Prefecture (YKAP), northern China. We conducted a series of field surveys and individual interviews (Chinese n = 1,000 and non-Chinese [foreign visitors] n = 100) on several aspects of the public squat toilet: structural properties, waste disposal methods, important factors, and overall satisfaction level. The significant factors in response to the public squat toilets were cleanliness, odor, toilet paper, temperature, soap, other facilities, and presence of cubicles. These factors should be policy priorities of the local government. In addition, 66.2% of Chinese and 91% of foreign visitors desired type E toilets (two full-high partition walls and a door). The results illustrate the nature of a sustainable and beautiful approach to the culturally and environmentally sound management of various types of public squat toilet in YKAP. The government needs to focus on the future-oriented and excreta treatment management of the sustainable toilet culture for residents and visitors of YKAP.

This study was conducted for clarifying distribution and characteristics of marshy Ericaceae plants on Mt. Changbai in China. The marshy Ericaceae plants in wetland of Mt. Changbai were investigated on about 1400 m altitude. This region is various developmental wetlands and vegetation mixture of needle-leaf trees and broad-leaf trees. This region also is start point of the coniferous forest zone in Mt. Changbai. As results of these researches, L. palustre var. diversipilosum and L. palustre var. decumbens populations were investigated in Larix olgensis var. amurensis community. R. lapponicum subsp. parvifolium var. parvifolium community appeared as a typical community. Environmental conditions of L. palustre var. diversipilosum and L. palustre var. decumbens populations' habitats are more soil humidity and shade condition. R. lapponicum subsp. parvifolium var. parvifolium community habitat, however, has more deposits and humidity condition. Therefore when the plants were cultivated, we should recognize the growth condition such as maintenance of humidity and control deposits. The flora of marshy Ericaceae species habitats was investigated as 28 families, 49 genera, 45 species, 14 variety, 1 forma, 1 sub-species, and total 61 taxa.

The purpose of this study was to compare clothing attitudes and the criteria for clothing selection between Korean and Korean-Chinese college female students in the Yanbian region of China. The subjects were selected as follows: 404 Korean female college students in the Choongchung area and 242 Korean-Chinese female college students in the Yanbian region of China. Questionnaires were used to collect the data and the data was analyzed by frequency, factor analysis, and t-test. The major results of this study were as follows: The clothing attitudes of the total respondents were classified into 5 factors: the fashion involving factor, the modesty involving factor, the economy conscious factor, the brand-name oriented factor, and the practical user factor. The modesty involving factor, the economy conscious factor, the brand-name oriented factor, and the practical user factor were significantly different between Korean and Korean-Chinese college female students. Korean consumers thought highly of the economy conscious factor and the practical user factor compared with Korean-Chinese college female students. However, Korean-Chinese college female students thought highly of the brand-name oriented factor and the modesty factor compared with Korean consumers.

To analyze the landslide susceptibility in Baekdu mountain area in china, we get two susceptibility maps using AcrView software through weighted overlay GIS (Geographic Information System) method in this paper. To assess the landslide susceptibility, five factors which affect the landslide occurrence were selected as: slope, aspect, soil type, geological type, and land use. The weight value and rating value of each factor were calculated by the two different methods of AHP (Analytic Hierarchy Process) and ANN (Artificial Neural Network). Then, the weight and rating value was used to obtain the susceptibility maps. Finally, the susceptibility map shows that the very dangerous areas (0.9 or higher) were mainly distributed in the mountainous areas around JiAnShi, LinJiangShi, and HeLongShi near the china-north Korea border and in the mountainous area between the WangQingXian and AnTuXian. From the contrast two susceptibility map, we also Knew that The accuracy of landslide susceptibility map drew by ANN method was better than AHP method.
