This paper reviews research outputs in Korea Journal of Population Studies (KJPS) and the changes in their contents during the period of 1977-2004. In the early years of KJPS, various types of outputs were published, but changes have been made into a direction that research articles compose the main context of the journal. As the journal published twice a year, the total number of articles of the journal shows a trend of marked rise. An analysis of the themes of articles shows that the trend of research in Korean demography has changed hand in hand with transformations of the Korean society. The traditional topics such as population policy, fertility, mortality, and migration were popular before. Labor force, nuptiality, family, aging, regional studies are found to be more popular themes of research recently. Reflecting academic and social demands, KJPS has a broaden range of authors, such as professor, researcher, a government employee, post-doc, and graduate students. The articles written by those working in universities have increased continuously, while research outputs of research institutes have decreased recently. The data for analysis used in articles are varied from but concentrated in some materials - census, vital statistics and various survey data. In early years of KJPS, relatively simple techniques of analysis were adopted in the majority of articles. However, more sophisticated techniques including applied regression analysis, logistic analysis and analysis of survival ratio turn out to be more popular recently. Finally, several suggestions for the future research are presented in this paper.

The environmental characteristics of the habitats, the population structures, ecological niche, life traits and the population demography are used as an essential informations to the effective conservation plans about the target species. We first confirmed a total of 37 populations through 12 years of investigation on the extents, and investigated the environmental factors of habitats and the population structures of the 25 cohorts in 12 regions among them. And, we investigated the population dynamics targeting at 8 cohorts in the population of Daegwanryeong-myeon, Pyeongchang-gun, Gangwon-do. Along with this, we conducted 4 years of cultivation experiments and how pollinators affect the success of reproduction. The results shows that the Paeonia obovata Maxim. was found in a relatively wide range of habitats. For the population structures of the 25 cohorts, there were considerable differences among cohorts, including a case which showed relative stable structure and an extreme case in which only adults were found. The factor that affected the population dynamics during the investigation was thought as a forest gap created in the tree layer. In the cultivation experiment, seedlings grew well in a less soil organic matter. The seed setting rate and the number of seeds generated by visiting pollinators were higher trends. In conclusion, to understand the distribution of the Paeonia obovata Maxim., there needs to be investigated on the other factors that are involved in dispersal factors other than environmental factors, and thus we suggest the necessity of the research on the dispersal vectors. The current Paeonia obovata Maxim. population was thought as a process of expansion after the rapid reduction of the extents in the past. For the effective conservation of the Paeonia obovata Maxim., an endangered plant, we recommend to understand the species through the spatio-temporal expansion, and maintain the health of the ecosystem based on it.

The main objective of this study is to conduct subnational population projections of Korea based on a multiregional cohort-component method. This objective is accomplished by: (i) establishing a viable framework to implement the multiregional cohort-component method with reference to the Markov chain model and Rogers' multiregional population projection model; (ii) applying the established framework to subnational population projections of Korea, 2005~2030. The main results are twofold. First, the proposed method turns out to be highly valid in a methodological sense, which is seen from a high level of coincidence between the estimated and the observed. Second, the projection results turn out to be highly useful in the sense that interregional migration flow matrices are resulted for projection periods. The projected migration flows are expected to provide invaluable information for an understanding of future population change and for a formulation of policy alternatives. This study is strongly inspired by the multiregional perspective emphasizing the evolution of multiple regional populations interconnected by interregional migration flows rather than the overall national change.

The purpose of the research was to investigate the characteristics and related factors of cyber dating violence. The subjects were 548 adolescents in high schools. The gathered information was analyzed by frequency, percent, 1-test, ANOVA, and Correlation by using SPSS 10.0 program. The results were as follows: (1) $65.3{\%}$ of the answerers experienced cyber dating, and $44.5{\%}$ of the students have experienced cyber dating violence. (2) $40.3{\%}$ of the students were damaged by psychological violence, and $21.1{\%}$ of the students have caused psychological violence. (3) $41.9{\%}$ of the damaged students and $18{\%}$ of the perpetrating students were included in the total answerers, but among 244 experienced students, $94.3{\%}$ were damaged students and $40.6{\%}$ perpetrated sexual violence, so it is concluded that experienced students experience sexual violence. (4) Looking over the social demography factors and cyber dating violence, boys rather than girls, and vocational school students rather than academic school students have more cyber violence experiences. (5) The relationship between psychological and sexual violence has a significant relationship with all cyber violence experiences.

Purpose - The Chinese government's policies and funds enable specialized farmers cooperatives to develop vigorously. However, the non-systematic supervision system affects the interests of farmer-members of these cooperatives, which are similar to the Korean NongHyup in many aspects but differ in their supervision systems such as distribution. Therefore, this paper aims to identify the problems of specialized farmers cooperatives, and obtain some insights from NongHyup. Research design, data, and methodology - Data were collected from farmers, the government, and cooperatives in northern China's Shandong Province (the cities of Jinan, Qingdao, Weifang, Linyi, and Heze) through a literature survey, case analysis, and comparative analysis in each city. Results - 1) Specialized farmers cooperatives should establish a transparent regulatory mechanism and be subject to dual supervision from both the Chinese government and farmers. 2) The Chinese government and civil society should offer more support to the cooperatives, and strive to change farmers' backward attitude through education and training. Conclusions - Small cooperatives could merge into large ones and undertake social responsibility through the establishment of labor unions.

Objectives: Clinically, patients with dyspepsia often complain of several gastrointestinal (GI) and extra-GI symptoms. However, there have been few studies investigating the relationship between GI symptoms and extra-GI symptoms. The aim of this study was to characterize the clinical features of the 991 outpatients with GI and extra-GI symptom and the relationships between GI and extra-GI symptoms. Methods: 991 patients newly visiting Weedahm Oriental Hospital for GI symptoms were included. Those who had disorders caused by the hepatobiliary-pancreatic system were excluded. The 991 outpatients were interviewed with a standardized questionnaire inquiring about demography, past medical history, past institutional care, GI symptoms and extra-GI symptoms. Results: Among 991 patients, 780 (78.7%) had more than three GI symptoms and 451 (45.5%) had more than five. Among 991 patients, 545 (55.0%) had more than three extra-GI symptoms and 285 (28.8%) had more than five. There was a statistically significant correlation between GI symptoms and extra-GI symptoms such as headache, fatigue, forgetfulness, eyeball pain, unrest, dizziness, muscle pain, chest pain, and dyspnea. Conclusions: We found that there was statistically significant correlation between GI symptoms and extra-GI symptoms, which suggests the possibility of main common pathophysiology between GI symptoms and extra-GI symptoms. Further studies will be required to elucidate the main common pathophysiology between GI symptoms and extra-GI symptoms.

Purpose: The purpose of the study was to evaluate the effect of the immediate postoperative nutritional status and calorie adequacy on clinical outcomes in liver transplant recipients. Methods: A total number of 99 patients who received liver transplants were recruited from a tertiary university hospital. Demography, subjective global assessment, clinical outcomes and calorie adequacy were evaluated through personal interviews, electronic medical records and dietary records. Anthropometric measures, body mass index and percent of ideal body weight were also obtained. Results: At admission to the Surgical Intensive Care Unit (SICU), the triceps skinfold thickness and mid-arm muscle circumference were significantly lower in the malnourished group than in the well-nourished group (p<.05, respectively). In the clinical outcomes, transfusion of red blood cells, mechanically ventilated hours, length of stay in the Intensive Care Unit (ICU), length of stay in the hospital, and prothrombin time were significantly higher in the malnourished group than in the well-nourished group (p<.05, respectively). The mechanically ventilated hour was significantly higher in the group with less than 50% of their required energy intake (p<.05). Conclusion: Therefore, it is important to assess the nutritional status of immediate postoperative patients. Furthermore, studies on nutritional interventions are urgently needed to provide adequate nutritional care for patients in ICUs.

We develop a mathematical model for the obesity dynamics to investigate the long term obesity trend with the consideration of psychological and social factors due to the increasing prevalence of obesity around the world. Many mathematical models for obesity dynamics adopted the modeling idea of infectious disease and treated overweight and obese people infectious and spreading obesity to normal weight. However, this modeling idea is not proper in obesity modeling because obesity is not an infectious disease. In fact, weight gain and loss are related to social interactions among different weight groups not only in the direction from overweight/obese to normal weight but also the other way around. Thus, we consider these aspects in our model and implement personal weight gain feature, a psychological factor such as body image dissatisfaction, and social interactions such as positive support on weight loss and negative criticism on weight status from various weight groups. We show that the equilibrium point with no normal weight population will be unstable and that an equilibrium point with positive normal weight population should have all other components positive. We conduct computer simulations on Korean demography data with our model and demonstrate the long term obesity trend of Korean male as an example of the use of our model.
