The most representative fruit in Yanbian area is Applepear(Ping Guo Li). It has been a important resource of farm income. According to the economic growth and income Increase of individual consumers, food consumption pattern will be changed from grain to high value cash crops such as Applepear and vegetables. The globalization and adapt ion of free market oriented economic policy of China government have led to change the collective farming system to individual farm management system. The institutional transformation have brought about high productivity of farm products and incomes of farmers. Therefore the plantation area of Applepear and requirement of investment cost for establishment of Applepear farms have increased rapidly since the 1980's, the time of perestroika and glasnost in Chinese economy. In prosperity of Chinese agriculture, individual farmer's decision making as free selection of farmland use, selection of high pay-off crops, free sale of the products in free market and credit support for the project might be the most important factors. In case of Applepear farm development, net present value of the project net benefit was estimated at 55.518won per hectare and financial rate of return was 21%. The benefit/cost ratio of the project was 2.11. Considering 10% of discounting rate or the opportunity cost of capital in China the Applepear farm development project showed us economically feasible in the light of the above efficiency indices. The Chinese government has to support Applepear farm development project financially and institutionally considering the high-payoff benefit of the fruit and farmer's in come increase in the future.

본 연구는 중국 철도망의 구조와 철도여객 및 화물 유동에 대한 분석을 통하여 중국 도시 네트워크의 특징과 변화를 밝히는 것을 주요 목적으로 하였다. 중국 도시의 접근성은 허난성을 중심으로 한 중부지역이 가장 높고 주변으로 향할수록 접근성이 떨어진다. 도시 네트워크의 중심은 중부지역에서 동부지역으로 이동하였으며, 3개의 남북방향 축과 주요 도시들의 지역 중심성은 여전하지만 그들의 영향권은 확대되고 중심성도 분산되었다. 도시 네트워크의 계층구조는 3단계로 구분할 수 있는데 1단계 계층에서 대부분의 영향권은 도시 성(자치구) 범위를 크게 벗어나지 않았고, 2단계 계층에서는 대부분의 지역에서 영향권 교차현상이 나타났으며 선형 패턴이 더욱 뚜렷하였다. 3단계에서는 5대 영향권으로 구분되었다.

이 논문은 중국내 조선족의 출산력 수준을 한족과 비교하고, 이에 관련되는 주요 결정요인들을 파악하기 위한 것이다. 이를 위해 우선 조선족이 19세기 중엽부터 중국의 동북지방으로 이주하게 된 역사와 배경을 기술하고, 지난 반세기 동안 조선족인구의 성장과정과 분포를 살펴보았다. 그리고 조선족의 출산력을 분석하기 위해서 1990년 중국인구센서스의 자료 중에서 길림성과 연변 조선족자치주의 표본자료를 활용하였다. 중국내 조선족인구는 다른 민족에 비해 상대적으로 고령화된 연령구조를 지니고 있으며, 교육수준이 뚜렷하게 높다는 특징을 지닌다. 출산력 수준은 한족이나 다른 소수민보다 현저하게 낮은 경향을 보이며, 이러한 경향은 조선족이 밀집되어 거주하는 지역일수록 강하게 나타난다. 조선족의 저출산력은 개인이나 가구의 인구학적 및 사회경제적 특성이 미치는 영향력을 배제하더라도 그대로 유의하게 유지되는 것으로 밝혀졌다. 또한, 이 연구의 분석결과는 지난 1980년대 후반 이래 중국에서 남아선호관으로 인하여 출생시의 성비가 높아지는 추세임에도 불구하고, 조선족의 경우에는 출생시의 성비불균형현상이 그다지 심각하지 않다는 것을 확인해 준다. 마지막으로, 이 연구에서는 한족이나 다른 민족보다 오히려 높은 수준을 나타내는 조선족의 자녀사망력에 대한 분석이 이루어졌다.

국제 이주에 대한 폭넓은 논의가 이루어진 데 반해 이주자가 출발지로 되돌아가는 귀환 이주에 대한 연구는 비교적 많지 않다. 이는 귀환 이주를 자본 축적 이후의 성공적 귀환이나 적응 실패로 인해 돌아가는 현상으로 비교적 단순하게 인식해왔기 때문이다. 조선족이 국내로 대거 이주해온 지 이십여 년을 넘기면서 귀화하는 사람뿐만 아니라 귀환하는 이도 어렵지 않게 볼 수 있다. 본 연구는 옌볜으로 귀환하여 자영업에 진출한 조선족을 대상으로 귀환 이주가 어떠한 전략적 선택 속에서 이루어졌는지 살펴본다. 최근의 옌볜 상업 경관은 귀환 조선족의 자영업 진출로 적지 않은 변화가 나타나고 있다. 특기할만한 점은 귀환 조선족에게 있어 한국 체류는 단순히 사업 자금을 마련하기 위한 것만은 아니었다는 것이다. 한국 경험과 네트워크는 옌볜에서 자본 축적의 새로운 기회를 찾고 넓히는 데 기여하고 있다. 이는 세계체제론 관점에서 옌볜 조선족 자영업자의 귀환이 주는 세계체제 간극을 활용한 자본축적 전략으로 해석될 수 있다.

Using statistic and bibliometric methods to characterize scientific cooperation between China (excluding Hong Kong, Macao, and Taiwan) and South Korea through their bilateral co-authored papers covered by the Science Citation Index CD-ROM, 1991-2010, in our paper we exploit the feature of their cooperation in four levels: time sequence, academic community, key fields, and institution distribution. From the time sequence we know that collaboration between China and Korea starts in 1991, reaching the first peak during 2004-2007. As for the academic community, the number of Chinese corresponding authors (2414) is slightly lower than that of Korea (2700). Regarding the 27 high yield authors, there are only 4 coming from China. Korea has a higher active level than Chinese authors. China and Korea tend to cooperate with each other on strong disciplines such as physics, chemistry, material science, engineering, mathematics, pharmaceutical, computer science and biology. Furthermore, they also attach great importance to basic research and high-tech cooperation. Besides, Chinese Academy of Sciences ranks at the top 1 among the distribution of institutions. As a majority of the collaborative institutions are universities, the participation of non-university institutions is relatively low. There are 7 Korean universities among the top ten institutions, while Yanbian University and Tsinghua University in China rank respectively as third and fourth. Seoul National University, accompanied by Korea University and Yonsei University as the three top Korean universities, is also among the top among the cooperating institutions.

과산화수소와 organic peroxide는 대류권내 광화학반응에서 생성되는 중요 부산물이다. 이들은 대류권내의 OH와 HO$_2$ 라디칼의 농도를 지시하여 대기의 산화도를 나타내는 지시자가 된다. 이 라디칼들은 $O_3$를 생성하는데 필수적인 성분이므로, 대류권내 광화학 반응을 이해하기 위해서는 과산화수소의 농도와 분포를 이해하는 것이 필수적이다. 대기중의 hydroperoxide는 유리코일 내에서 포집 용액에 의해 포집된 후 HPLC 시스템의 postcolumn reactor에서 효소와 반응하여 형광을 띠게 되고, 형광검출기에서 검출된다. 이 모든 과정은 자동화되어 과산화수소의 실시간 관측 및 연속관측이 가능하게 되었다.
