이 연구는 개혁개방정책 이후 중국 내 조선족이 보인 사회인구학적 행태의 변화를 설명하기 위한 것이다. 시장경제체제의 도입과 한중 국교수립 이후 조선족사회는 출산력수준의 급격한 저하와 인구구조의 고령화로 매우 급격한 변화를 겪고 있다. 조선족의 인구행태와 인구구조의 이러한 변화는 한족에 비해 두드러지게 나타난다. 중국 내 조선족인구가 가장 밀집되어 거주하고 있는 연변지역의 조선족사회는 최근 절대인구규모의 감소추세를 보이고 있다. 아울러 시장경제의 도입 이후 이동성향이 높아지고 통혼권과 거주지역이 확산되며. 조선족학교를 통한 민족교육이 급격히 위축되는 추세를 보인다. 그리고 이에 따라 조선족사회의 사회적 통합과 문화정체성이 약화되고 중국 내 소수민족사회로서의 위상도 점차 약화되는 과정에 있다. 연변 조선족사회의 사회인구학적 변화와 위기상황에 대한 설명을 위해 이 연구는 연변조선족자치주의 1990년과 2000년 인구센서스 자료와 각종 통계자료를 활용하였다. 또한, 이 연구에서는 인구센서스를 통하여 드러난 조선족인구의 연령구조가 매우 불규칙적이라는 점을 감안하여 1990년과 2000년 인구센서스 자료의 신뢰성과 정확도를 재검토하는 작업도 이루어졌다.

China's population and family planning program has heen successful. Women's fertility as measured by total fertility rate (TFR) has declined from 5.8 in 1970 to 2.3 in 1990, accordingly the annual crude birth rate(CBR) has declined from 34 per thousand in 1970 to 21 per thousand in 1989, and the annual natural growth rate from 2.6 percent in 1970 to 1.4 percent in 1989 (Coale and Chen, 1987; SSB, 1991; Gu, 1994). While this is indeed an astonishing achievement for a developing country to have its fertility down to replacement within a short period, some new issues emerging along with the rapid fertility decline require careful considerations. One of them is the uprising of the sex ratio at birth in China. The 1990 population census reported the sex ratio at birth in China of 113.8 in 1989, which is ohviously much higher than the acceptable level of normal ratio around 106. It has received since then a lot of tention in China and abroad, among demographic professionals and governmental agencies alike (Hull, 1990; Johansson and Nygren, 1991; Xuand Guo, 1991; Tu, 1993; Gu and Xu, 1994; among others). Based on the available demographic data and research results this paper will first have a review of the patterns and trends of sex ratio at birth in China, then turn to the immediate causes of abnormal sex ratio at birth and the determinants of the son preference, followed with a conceptual framework for understanding of the phenomenon, and finally the policy implications and recommendations will be discussed.

Large scale marine biodiversity studies in China have been carried out for more than half a century since the founding of the Institute of Oceanology, CAS, in 1950. Through a series of coastal and multi-disciplinary oceanographic investigations in the shelf seas and biodiversity studies since the late fifties, a total of 20,278 species of marine biota have been recorded upto 1994. Recent intensive studies have further revealed the richness of marine biota of the China seas,a great number of marine species have been found and many new taxa established. The total species number of main biotic groups increased about 50 % of that estimated in 1994. The results have promoted the fast development of China's marine fisheries, medicine (drug) and biodiversity research, and attracted many scientists, particularly bio-technologists, to join their studies. Environmental deterioration and human activity strongly stressed the sustainable development and conservation of marine bio-diversity, and resulted in the increase of end angered species as record ed in the new published ${\ll}$China Species Red List${\gg}$ with the threatened category of species assessed by adopting the new IUCN criteria. To further reveal the high diversity and their history, present status and future of marine organisms existed in the world ocean, an international Project ${\ll}$Census of Marine Life (CoML)${\gg}$ was established in 2000 in the USA. Scientists predicted that 2 to 3 times of numbers of the known species will possibly be found in various marine habitats, particularly the abyssal ocean. The Research Plan and the Projects were briefly introduced, and the relationship between marine biodiversity and biotechnology was discussed. The Project planned to apply new and high techniques and new equipments on board research vessel and in laboratory. Brief review of recent advances of Chinas' marine biodiversity and biotechnology studies indicated that fascinate results have been achcieved; but further effort should be made to promote the continuous advance of our basic researches and their application in related production and maintain sustainable development.

이 연구는 상이한 성선호의 문화적 전통을 지닌 인종집단들을 대상으로 하여 의료수준과 유아사망력의 관계를 파악하기 위한 것이다 이를 위해 1990년 중국인구센서스 중에서 연변자치 주에 거주하는 조선족과 한족 그리고 서쌍판납자치주의 한족과 다이족의 원자료를 활용하였다. 이 논문은 성선호, 사회경제적 수준, 의료수준과 유아의 성별 차별사망력의 관계를 설명하기 위한 새로운 모형을 제시하고 있다. 의료인력이 널리 가용한 지역사회에서는 유아사망력의 수준이 성선호에 의하여 영향받을 가능성이 낮다. 그러나 지역사회의 의료수준이 낮으면, 특정한 성을 선호하는 경향이 강한 인종집단의 구성원들은 선호하는 성의 자녀들의 생존을 위하여 모든 노력을 기울이게 될 것이다. 이에 반해서 부모들이 선호하지 않는 성의 자녀생존을 위한 행위들은 이에 수 반되는 비용이나 여러 가지 조건들에 의하여 영향을 받게될 것이다. 따라서 선호하는 성의 유아사망력의 수준은 선호하지 않는 성의 그것에 비해 월등히 낮을 가능성이 크다. 그러나 사회경제적 발전과정에서 의료수준이 향상되고 이에 수반되는 비용이 낮아지면, 선호하지 않는 성의 유아사망력은 급격히 감소하고 성별 사망력의 차이는 줄어드는 경향을 보이게 된다. 이 연구에서 강한 남아선호관을 지닌 조선족 및 한족과, 반대로 여아를 선호하는 경향이 강한 다이족의 유아사망력을 분석한 결과는 이러한 명제들을 뒷받침 해준다.

Background: The National Central Cancer Registry of China (NCCR) affiliated to the Bureau of Disease Control, National Health and Family Planning Commission of China is responsible for cancer surveillance in the entire country. Cancer registration data from each local registry located in each province are collected by NCCR annually to be analyzed and published to provide useful information for policy makers and cancer researchers. Materials and Methods: Until 1st June, 2013, 219 population-based cancer registries submitted data of 2010 to the National Central Cancer Registry of China covering about 207,229,403 population, and 145 cancer registries were selected after quality evaluation for this study. Colorectal cancer cases were selected from the database according to ICD-10 coded as "C18-C20". We calculated the crude incidence and mortality rates by sex, age groups and location (urban/rural). The China population in 2000 and Segi's population were used as standardized populations for the calculation of age-standardized rates. The 6th National Population Census data of China was used to combined with the cancer registries' data to estimate the colorectal cancer burden in China in 2010. Results: Colorectal cancer was the sixth most common cancer in China. It was estimated that there were 274,841 new cases diagnosed in 2010 (157,355 in males and 117,486 in females), with the crude incidence rate of 20.1/100,000, highest in males in urban areas. Age-standardized rates by China standard population of 2000 (ASRcn) and World standard population (Segi's population, ASRwld) for incidence were 16.1/100,000 and 15.9/100,000 respectively. There were 132,110 cases estimated to have died from colorectal cancer in China in 2010 (76,646 men and 55,464 women) with the crude mortality rate of 10.1/100,000. The ASRcn and ASRwld for mortality were 7.55/100,000 and 7.44/100,000 respectively, higher in males and urban areas than in females and rural areas. The incidence and mortality rates increased with age, reaching peaksin the 80-84 year old, and oldest age groups, respectively. Conclusions: Colorectal cancer is one of the most common incident cancers and cause of cancer death in China. Primary and secondary prevention, with attention to a health lifestyle, physical activity and screening should be enhanced in the general population.

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.

본 연구는 분석기간을 1952-2008년으로 설정하고, 제1차 전국경제조사에 의한 수정 후의 지역별 GDP자료를 이용하여 중국의 지역경제발전 격차의 추세를 분석하고 있다. 연구결과를 종합하면 아래와 같다. 첫째, 수정 후의 자료를 이용한 변이계수가 수정 전의 변이계수보다 낮다. 둘째, 전반적으로 개혁개방 이전 시기보다 개혁개방 이후의 시기에서 더 낮은 격차를 나타내고 있다. 특히 1990년대 이후 지역 간 발전 격차가 급속하게 확대되는 것이 아니라 완만한 축소과정을 거치면서 확대되고 있다는 점이다. 이것은 기존의 연구와는 다른 결과이다. 셋째, 2002년을 기점으로 새로운 역U자형의 주기가 나타나고 있다. 넷째, 허핀달-허쉬만지수(HHI)와 테일엔트로피지수(TEI)의 비교에 의하면, 개혁개방 이후 1980년대에는 상대적으로 저(低)발전 지역의 발전이 전체 지역 간 격차의 축소에 더욱 큰 영향을 초래하고 있으며, 2000년대 이후에 또 다시 상대적으로 저(低)발전 지역의 발전이 지역 간 발전 격차의 축소에 더욱 중요한 역할을 담당하고 있음을 발견하였다. 다섯째, 수렴가설의 검증 결과에 의하면, 분석기간을 1978년-2008년을 설정할 경우 개혁개방이후에 지역경제발전 격차는 수렴하고 있다는 가설을 채택할 수 있다. 여섯째, "역U자 가설" 검증 결과에 의하면, 전체 분석기간인 1952년-2008년에서는 "역U자 가설"이 채택되지 않았다. 단지 1991년-2008년 기간에서만 역U자 가설이 채택되고 있다. 이것은 위의 변이계수의 추계 결과도 같은 맥락이며 또한 수렴가설의 검증 결과와도 거의 같은 의미를 가지고 있다.

The rapid urbanization in many Asian countries has taken millions of people from the rural countryside to concentrated megacities, which eventually putting pressure on the existing water resources. The over-growing population and increasing living standard of people in the urban region of developed as well as developing countries such as Korea, China, Japan and India have witnessed a drastic change in terms of domestic water demand for the past few decades. In this study, we used the concept of potential surface water availability in the form of surface runoff for future vulnerability assessment. We focused on 42 megacities having population more than 5 million as per the United Nations (UN) census data 2020. The study shows that 30 out of 42 cities having more than 180L/p/d demand for domestic use based on various references. We have predicted the domestic water demand for all the cities on the basis of current per capita demand up to 2035 using UN projected population data. We found that the projected water demand in megacities such as Seoul, Busan, Shanghai, Ghuanzou are increasing because of high population as well as GDP growth rate. On the contrary, megacities of Japan considered in our stud shows less water demand in future due to decreasing trend of population. As per the past records provided by the local municipalities/authorities, we projected different scenarios based on the future supply for various megacities such as Chennai, Delhi, Karachi, Mumbai, Shanghai, Wuhan, etc. We found that the supply to demand ratio of these cities would be below 75% for future period and if such trend continues then the inhabitants will face serious water stress conditions. Outcomes of this study would help the local policy makers to adopt sustainable initiatives on urban water governance to avoid the severe water stress conditions in the vulnerable megacities.

Objective: The Zhejiang Provincial Cancer Prevention and Control Office collected cancer registration data during 2000 to 2009 from 6 cancer registries in Zhejiang province of China in order to analyze the cancer incidence. Methods: Descriptive analysis included cancer incidence stratified by sex, age and cancer site group. The proportions and cumulative rates of 10 common cancers in different groups were also calculated. Chinese population census in 1982 and Segi's population were used for calculating age-standardized incidence rates. The log-linear model was used for fitting to calculate the incidence trends. Results: The 6 cancer registries in Zhejiang province in China covered a total of 60,087,888 person-years during 2000 to 2009 (males 30,445,904, females 29,641,984). The total number of new cancer cases were 163,104 (males 92,982, females 70,122). The morphology verified cases accounted for 69.7%, and the new cases verified only by information from death certification accounted for 1.23%. The crude incidence rate in Zhejiang cancer registration areas was $271.5/10^5$ during 2000 to 2009 (male $305.41/10^5$, female $236.58/10^5$), age-standardized incidence rates by Chinese standard population (ASIRC) and by world standard population (ASIRW) were $147.1/10^5$ and $188.2/10^5$, the cumulative incidence rate (aged from 0 to 74) being 21.7%. The crude incidence rate was $209.6/10^5$ in 2000, and it increased to $320.20/10^5$ in 2009 (52.8%), with an annual percent change (APC) of 4.51% (95% confidence interval, 3.25%-5.79%). Age-specific incidence rate of 80-84 age group was achieved at the highest point of the incidence curve. Overall with different age groups, the cancer incidences differed, the incidence of liver cancer being highest in 15-44 age group in males; the incidence of breast cancer was the highest in 15-64 age group in females; the incidences of lung cancer were the highest in both males and females over the age of 65 years. Conclusions: Lung cancer, digestive system malignancies and breast cancer are the most common cancers in Zhejiang province in China requiring an especial focus. The incidences of thyroid cancer, prostate cancer, cervical cancer and lymphoma have increased rapidly. Prevention and control measures should be implemented for these cancers.
