Yanbian Korean Autonomous Prefecture(YKAP) possesses the potential to become the first testing ground for the North-East Asian Energy Cooperation in renewable energy sector. We found that production of biodiesel from rapeseed and CHP (Combined Heat and Power Plant) project utilizing abundant forest resources are the two main bioenergy development projects which may have further development potential considering the resource endowments and the focus of Chinese governments' current rural development policy. Provision of stable and transparent investment environments and the development of a close cooperation mechanism between Korea and China government are the prerequisite conditions for investments in the sector. Other international institutional agreements, such as CDM, shall be fully utilized for biomass CHP projects.

Purpose: This study was to investigate depression in Korean-Chinese elder living in the Yanbian Korean Autonomous Prefecture in China. Methods: A cross-sectional community-based survey was conducted using face to face private interviews for elders aged over 59, who have been dwelling in the Yanbian Korean Autonomous Prefecture. The samples consisted of 183 Korean-Chinese and 182 Han-Chinese with the latter as a reference group. Data were collected from August 25 to September 20, 2011 and analyzed with the SPSS 18.0 program. The GDS (Geriatric Depression Scale) was used to measure elderly depression in the subjects. Results: In Korean-Chinese, the rate of depression was higher in those who had lower educational levels, and were economically supported by the government. And those who had depression showed lower scores in Chinese language proficiency, health status, and social supports, and had more chronic diseases. Factors having effects on Korean-Chinese elderly depression included perceived health status and subjective support. Conclusion: According to the results, for preventing the depression of Korean-Chinese, it is necessary to develop health management programs and social support networks, which were easy to approach.

This Research is to study types and distribution for place name of migration derived from Korea Peninsula by analyzing villages name of the Yanbian Korean Autonomous Prefecture. Village names of Yanbian Korean were identified as 945 out of 2,015. Place name migrated from Korea Peninsula was turned out 51 villages. Up to the present time in the Transition of China, 34 place names were disappeared, maintained place names were 16, and rehabilitated place name after loss was 1. The place name by naming method were classified as small area directed migration, large area directed migration, and merged migration. In case of small area directed migration, origin and destination is same such as Jeongeup and Muju, Cheonbuk, large area directed migration is named case by region migrants like a Gangwonchon named by people moved from GanwonDo, and merged case combine initials with each village names in case of GilseongChon by colligated Gilju and Seokseongmyeon. The results will be expected to support research information for identity and ethnical migration process.

In terms of world system theory, the historical period of Yanbian area was divided into 3 parts: Japan colonial period which was assigned to the periphery of world system, socialist period which escaped from the world system, and the reform-open period that was reincorporated to world system. The cultural character of each period was studied. The conclusions are as follow. During the period of periphery of world system, Yanbian area as an area where the massed Korean people lived, was dominated by Korean peninsular culture. However, Yanbian area was also affected by the Japanese and Chinese cultural assimilation policy. During the period that Yanbian area aparted from the world system, it was affected by the requirement of unique socialist culture assimilation, and traditional cultures were hard to keep. During the period of reincorporation to the world system with lighten of minority policy by Chinese government, traditional national culture begin revived, but due to extend intercourse of Yanbian with China mainland and Republic of Korea, China-Korean culture of Yanbian area was strongly affected by Chinese and Korean culture too.

This paper attempts to explore recent socio-demographic changes of the ethnic Korean population in Yanbian autonomous prefecture. Due to rapid decrease in the level of fertility and population ageing, Korean minority society in China has been in a process of profound transition after the introduction of the market economy and establishment of diplomatic relations between South Korea and China. The changes in demographic behaviors and in the structure of population appear to be much faster among Koreans than Hans. Results from the 2000 population census reveal that the Korean population in Yanbian, where ethnic Koreans are most densely populated in China, has been in a decreasing trends in absolute numbers and in its proportion to the total population. The growing tendency of regional mobility for work and for marriage, rapid expansion of residential areas, serious crisis of ethnic schools of Korean community, and weakening social integration and ethnic identification of Koreans in Yanbian are discussed in this study. It is expected that socio-demographic transition of Korean society in Yanbian will be even more drastic over the coming decades. The rapid changes in demographic behaviors and in the structure of population has major consequences and implications for every sphere of human life, and will present enormous challenges for the status of Korean minority society in China. Along with various statistical data on Yanbian, micro-level data as well as published reports from the 1990 Chinese population census for Yanbian and the 2000 Chinese population census are analyzed in this study. In addition to sex ratios and age ratios, various indices are calculated to analyze the characteristics and accuracy of the data from the 1990 and 2000 population censuses of China.

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.

To understand the changing regionality of the Yanbian Korean Autonomous Prefecture(YKAP) in China within the world-economy, this paper examined the spatial division of labor in agriculture and industry with three divisions of period through the regional geography of world-system In the Japanese colonial period(l909$\sim$1949), the YKAP was made into a typical peripheral agricultural and industrial region which was exploited by the Japanese empire. In the socialist period(1949$\sim$1978) which China separated from the world-system, the YKAP was transformed into a socialistic agricultural and industrial region. In the reform and open-door period(1978$\sim$present), the YKAP still plays a role as a peripheral region due to the late open-door policy in 1992 of Chinese government on the border land and else, while most littoral areas of China are developed into a semi-peripheral region. Therefore if the YKAP continues to exist in the future, it is a critical matter to raise the position of the YKAP within the world-economy into a semi-periphery as soon as possible to increase the ratio of Korean ethnic in the YKAP.

This study investigates dialectal differences in the acoustic properties of Korean lenis, aspirated, and tense stops Seoul Korean (standard Korean) and Yanbian Korean (spoken in the largest Korean Autonomous Prefecture in China). This production study the main acoustic cues that each dialect uses to mark the laryngeal distinction between the three types of Korean stops. Measurements included VOT, and the initial F0 of the following vowel. Data collected from 10 young Seoul Korean speakers, 10 young Yanbian Korean speakers, and 6 older Yanbian speakers. two key findings: First, aspirated and lenis stops are mainly differentiated by F0 in Seoul Korean, and by $H1^*-H2^*$ in Yanbian Korean. Second, there is no VOT merger between lenis and aspirated stops in Yanbian Korean, whereas there is in Seoul Korean. These results are discussed in terms of the phenomenon of VOT shift and the function of F0t is argued that the function of F0 to substitute for VOT difference as a primary cue for the coding of laryngeal contrast can be predicted by the pitch accent system of the language involved.

We examined the heading responses of rice varieties over two years in Dandong, China to select the varieties that are adaptable to the bordering northwestern plains of North Korea. Dandong had slightly lower mean temperature than Sinuiju, North Korea but slightly higher than Supung, but it had almost the same day-length as the two regions in North Korea. In the two experimental years and two transplanting-date treatments, eight varieties (Jinbuol, Baegilmi, Joun, Jinok, Jopyeong, Jinbu, Sanhomi, and Odae) from South Korea and five varieties (Olbyeo2, Sonbong9, Onpo1, Gilju1, and Pyongdo5) from North Korea reached the heading stage not later than the latest heading dates of Dandong domestic varieties and the safe marginal heading dates of Dandong. We examined the basic vegetative phase (BVP), photoperiod-sensitivity (PS), and thermo-sensitivity (TS) of rice heading in a phytotron study to characterize the heading ecotypes of rice varieties adaptable to Dandong. For the rice varieties grown in Dandong experimental field, number of days to the heading stage was highly positively correlated with PS and, except middle and mid-late maturing three varieties, it was significantly positively correlated with BVP. Two-dimensional distribution plotting revealed that both 35 days or less BVP and 25 days or less PS were the characteristic heading ecotypes of the rice varieties adaptable to Dandong.
