In order to analyze growth and yield of rice population at the stand point of productive ecology, productive structure and growth rate of rice plants and effects of their related factors were studied. The results obtained were summarized as follows: 1. High crop growth rate was maintained throughout growing season when rice plants grew in population compared to a single rice plant. Since crop growth rate in rice stands were also higher at ripening stage, higher yields were obtained. 2. Higher crop growth rate of rice plants in population was maintained by the increase of leaf area rather than by net assimilation rate. 3. As the overgrowth of upper leaves of plant population in some rice varieties transmission of light into lower leaves was inhibited and thus most of them were eventually died before flowering. 4. In the case of rice population, the ratio of productive organ to non-productive organ, light transmission rate and nitrogen contents of active leaf blade were lower than individual rice plants under isolated condition.

Current discussions on productive aging are going towards the direction to sustain a social productivity and lessen a social burden, and this becomes distinct as it gives a strong value to the activity and independence of older people. This study highlights complex situations of productive activities in the group of older people by analyzing the survey of Among the productive activities of older people, two areas of activities - paid labor and social support - were interpreted differently according to their economic stability, spontaneity and family relations. This difference becomes more remarkable in the analysis on life satisfaction of older people. In paid work, which is the most common productive activity, there was a big difference in life satisfaction between those who work spontaneously and those who work inevitably to make a living. And in the comparison of life satisfaction for those who participate in homemaking and care working according to their economic situations and family relations, those who were unsatisfied with family relations showed lower life satisfaction.

The purpose of this study is to discuss the economic outlook of dentistry in relation to pessimistic economic perspectives of Korea and to present subsequent solutions. The expectation of the future economic growth rate of Korea is gloom with not only a love rate of increase in population due to an aging society and a low birthrate, but also with a declined number of productive populations. Moreover, the future of dentistry in Korea is obscure. Even with a dwindling population growth, an average of 750 new dentists graduate from dental school every year. The 30-35% of the new graduates practice in public hospitals; and 65~70% of them open up their own private practices, However, unlike in the past, the occurrence of dental practice bankruptcy has been increasing with a competitive environment, excessive initial investment, knowledgeable patients, and etc. Therefore, it is essential to re-evaluate the number of new graduates. Also, it is necessary to supply a greater number of public hospitals with newly licensed dentists, who have various clinic experience, participate in research and development, and experience appropriate hospital management skills.

The purpose of this study was to interpret the transformation of Cooperative Groups for Agricultural Production(CGAP) with the change of the Agricultural Productive Force. The specific objectives were; 1) To investigate the change of agricultural labour-power, 2) To investigate the change of agricultural mechanization and arable land, 3) To interpret the transformation and content of CLAP. The population of farmhouseholds has decreased continuously since the late 1960s. Especially, with the move-outs of youth ages of twenties to forties, the condition of agricultural labour-power has been more serious. The processing of agricultural mechanization was a small scale step in the 1970s, but after the 1980s there was a spread of middle-large machines. However the usage rate of agricultural machines was constrained by the bad conditions of arable land. From the 1970s to now, the CGAP have bean processed by many kinds of patterns. In the 1970s, the lack of labour-power caused the creation of the Co-Working Team. After the late of 1970s, the wage of agricultural employees was raised, because the working population of agriculture was cut down. Also, the induction of agricultural machine was promoted. As a result, in the 1980s, the Machine-Using Team occurred due to these conditions of agricultural productive force. In the late of 1980s, the population decreased more rapidly, and the use of large machines were spread. Than farmhouseholds laking labour-power gave a trust to other farmhouseholds and Teams which had machines. In 1990, Given-Trust Cooperations were enacted by law, and in order to overcome the lack of labour-power, and solve the problem of the successors of agriculture, Cooperative Organizations were also enacted by law. Finally, in Korea from the 1970s to now, as the agricultural productive force has barn changed, the Co-Working Team was transformed into the Machine-Using Team, and the Machine-Using Team was transformed into the Given-Trust Cooperation, and the Cooperative Organization.

The residential population of Jeju Island has increased more than 10% for last 10 years. Especially, the tourist population is more than twice comparing to 2005. The population growth of Jeju has brought about large-scale urban development and increased land demands for tourism services. The goal of this study is to analyze the human, social, and environmental status of Jeju Island and to evaluate the environmental capacity of land use using ecological footprint (EF) model. This study shows the changes in ecological deficits of Jeju Island through estimating ecological productive land (EPL) considering EF from 2005 to 2015. The categories of total EF consists of food land, built-up land, forestry, and energy consumption. In order to reflect the characteristics of resort island, we consider not only residential population but also tourist population who can increase land demands. The outputs of this study also provide the potential excess demands of EPL and suggest needs of sustainable management plans for the limited land of Jeju Island.
