The major purpose of this study is to collect the information related on the aspects of economic efficiency for solving the problems which are faced by farmers and areas, and providing scientific facts to farmers and related institutions for further development of sericultural sector in Korea. In order for obtaining the related information 12 sample areas among 23 major sericultural farming areas and 30 farm units in each area are selected and analyzed in this study. The fold suevey is made by member of this study team and graduate students in the Department of Sericultural Science with a prepared questionnaires. Cross-section and regression analysis methods are employed for processing the data in this study. The major findings obtained are as followings. 1. Sericultural earnings per Tanbo is, on the average, 22, 752 won in new cultivated areas and 29, 403 won in ordinary ones. There are big difference in the size of earnings by areas, especially, 46, 968 won in Kumo mountain area, compared with 16, 798 won in Yeoju and Yichun areas. General trend is finded that small scale farming units are made higher earnings and operating their farms efficiently. 2. Cocoon production expences per Tanbo is 16, 737 won in new cultivated areas and 19, 802 won in ordinary areas. There are also big difference in farming expences, especially, 27, 389 won in Sudang area, compared with 11, 689 won in Emjin area. 3. Sericultural income per Tanto is 10, 664 won in ordinary areas and 6, 898 won in new cultivated areas. Farmers in Kumo mountain area make the highest income of 21, 164 won and lowest income of 1, 296 won in Sudang area. It can be generized that about 30-50 a sized farmers make higher income. 4. Land, labor and capital productivities estimated by fitting Cobb-Douglas functions in ordinary areas are higher than in new cultivated areas, especially, labor productivity is higher in ordinary areas. 5. Changsung, Kwangna, Yunsun and Kumo mountain areas are technically and economically efficient. Sudang and Mujinchang areas are technically successful but economically inefficient and Emjin and Honam areas are technically inefficient but economically efficient. YeojuYichun, Chunwon and West Kyongnam are technically and economically inefficient. Technical and economic improvement program should be implemented for these areas. 6. Estimated Internal Rate of Return (IRR) on capital investment in Chongwon are is 23.5 percent. It is economically feasible, if we consider 20 percent of opportunity cost of capital in our economy.

Korea's rapid urbanization caused problems, such as destruction of the rural environment, loss of traditional culture and dissolution of communities, as the continuous outflow of the population from rural areas, aging and consequent labor shortages and deterioration of the living environment were connected like a vicious cycle. In order to solve the problems of rural areas and overcome their vulnerabilities, the ultimate goal is to find a way to reintroduce the population to the rural areas. In order to be reborn as a space with rural characteristics and pluralistic functions and various potentials in a space under threat of underdevelopment and extinction, the pushing factor from rural areas is improved, and the population inflow factor to the rural areas is improved to enhance rural attractiveness, focusing on creativity among the 4Cs of New Ruralism: Conservation, Cultivation, Community, Creativity. A case study of 'Creative space in rural areas' was studied and considered. In-depth interviews were conducted with four key stakeholders, and the research results were analyzed focusing on the grounded theory method to draw implications from the background of Gurye Natural Dream Park, characteristics that can be viewed as creative spaces, and examples of creative space creation in rural areas. The 'Creative space in rural areas' is a space that can solve the current issues and problems of rural areas. In the case of Gurye Natural Dream Park, the young population of Gurye is increasing through job creation, provision of living and cultural service facilities, and improvement of the education and medical environment. In this study, the existing rural problem-solving process in this process was viewed as creativity in rural areas.

New cities and industrial complexes are being developed actively because of the government policies aiming population distribution and vitalization of construction industry. To determine the investment amount, number of power lines and substations for stable power supply to newly developed residential and industrial complexes, accurate estimation of power demand is necessary. This paper propose standards for the estimation of power demands for power company and construction company to settle the debates surrounding this issue. Through a survey and analysis of existing areas, new standards that will enable more accurate estimation of power demands in new cities complexes to be developed in the future are established by calculating the average load density, load factor, utilization factor by area, use and building size after dividing the facilities into building type and the areas into the areas planned to be developed and the areas not yet planned to be developed.

This study investigated how the contents of biology domains that were dealt with in the 7th national elementary-school science curriculum were in turn dealt with in the other subject matter areas. Through this, it was hoped that the place and identity of biology as a subject could be more clearly established and defined and additionally, more basic data for developing the new national science curriculum could be acquired at the same time. Subject matter areas that overlapped with biology in the 7th national elementary-school curriculum were practical arts, social studies and physical education. The structure and composition of specific components that were dealt with by these subject matter areas were very different from those of science, and the analysis showed that they failed to correspond across grades. Moreover, topics such as 'natural calamities and the environment' and 'human reproduction' that were dealt with by other subject matter areas, but not in science must be included for developing the new national science curriculum. Accordingly, when it comes to composing the contents of each subject matter area during creation of the new national curriculum, the relevant experts in related subject matter areas should be mobilized to conduct in-depth analysis of the following areas: viability, the most appropriate level of difficulty, and appropriateness of any hierarchy of relative importance between subjects. Additionally, efforts to reflect any improvements in the way the new national curriculum is developed which come about through this research are needed.

This paper reviewed major GDSS literatures from the "groupthink" standpoint, proposed a new framework for GDSS research, and suggested research issues. Despite a sizable amount of GDSS research for a dacade, the results tend to lack consistency, and still more studies are needed in many areas. One way to overcome the limitations is the thorough review of GDSS literatures and "groupthink" theories. Especially, groupthink/decision-making literatures provide many useful insights and guidelines for further exploring new GDSS research areas.

This study has identified human performance research issues associated with the implementation of new technology in nuclear power plants (NPPs). To identify the research issues, current industry developments and trends were evaluated in the areas of reactor technology, instrumentation and control technology, human-system integration technology, and human factors engineering (HFE) methods and tools. The issues were prioritized into four categories based on evaluations provided by 14 independent subject matter experts representing vendors, utilities, research organizations and regulators. Twenty issues were categorized into the top priority category. The study also identifies the priority of each issue and the rationale for those in the top priority category. The top priority issues were then organized into research program areas of: New Concepts of Operation using Multi-agent Teams, Human-system Interface Design, Complexity Issues in Advanced Systems, Operating Experience of New and Modernized Plants, and HFE Methods and Tools. The results can serve as input to the development of a long-term strategy and plan for addressing human performance in these areas to support the safe operation of new NPPs.

Current, integrated schools are small schools in rural areas and old towns with declining population, or special purpose middle and high schools. And new residential districts in urban areas including Seoul have also been established in integrated schools. In particular, the number of school of central investment evaluation for integrated schools in urban areas is increasing. In this way, integrated schools, which have been mostly implemented in small rural areas, are being introduced as new ways to establish schools in urban housing development areas where the number of students is small or the number of students is difficult to predict. However, many studies of integrated school have been limited to appropriate scaling of small schools in rural areas, school management methods, and satisfaction surveys. The study of integrated school in urban areas is also focused on the study of architectural planning. In addition, there were limitations in suggesting the comprehensive establishment plan of schools or approaching urban planning when developing housing complexes. The purpose of this study is to suggest efficient establishment plan of integrated school in the development of urban housing complexes.

After opening Suwon railway station in 1905, a new road was constructed between Suwon station and Paldalmun(the South gate). It was the starting point to change urban structures of Suwon and shape the new city scape. In 1914, administrative districts of Suwon were reorganized. Suwon-myeon (township, a subdivision of Suwon-gun) was promoted to Suwon-eup(town) in 1931. Suwon-eup expanded its territory and changed the address system from 'li(里)' system to Japanese address system, 'Jeong(町)' in 1936. From 1920s, road system was changed and transformed Suwon's urban structures. A straight road was built from Jongro intersection to Janganmun(the north gate) in 1928. Another straight road was constructed between Suwon station to Padamun in the early 1930s. Public office buildings used the Hwa Seong HaengGung(華城行宮) and some of building moved to new location with new buildings. Main buildings of most schools in Suwon were reconstructed since 1930s. Commercial buildings and stores were sprung up and had their own characteristics by region. Around Suwon station, there are more hotels and restaurants than other areas. Rearranging administrative areas, developing road system and new buildings transformed Suwon's spatial structures. Constructing new roads formed a straight road passing through Suwon. After reorganizing administrative areas, this road turned to be the central axis of Suwon. Buildings in new style on the axis made the modern cityscape in Suwon.

Environmental issues had arisen following industrialization with rapid physical growth of city and its consequences: widened metropolitan areas, uncontrolled reconstructions of new metropolitan areas, many social issues, such as declines of existing metropolitan areas. Due to these issues, new development policies have been made in order to find identities and reconstruct new images of cities. This research aims to remind the meaning of conservation of modern construction and building re-use, and to identify values of modern architectures in the context of a city. Regeneration of cities is not only finding national identities, but also expecting to increase inflow of foreign travellers. However, this regeneration hasn't stayed sustainable, focusing only on short-term curing of the problem in limited areas. This work analyzes cases of modern architecture, historic buildings from various cultures: Western, Japanese, Chinese. The result of the analysis shows that the value of existing buildings and citizen participation is necessary to revitalize cities. Four characteristics have been also identified: historic relationship, spatial identity, spatial presence, and approachable efficiency. For a potential solution, cities need to be viewed from multiple perspectives to find a method to generate new vitality for a city whose values should be recognized as an asset through sustainable re-use, by transforming modern construction as a heritage.

This study analyzed various indicators of new stores targeting urban regeneration areas and compared them with the control group to evaluate the possibility of revitalization of areas where urban regeneration projects are taking place. The results of the study are divided into three categories. First, the density of new start-ups in urban regeneration areas was higher than that of the control group. Through this, urban regeneration areas will bring about an influx of new floating populations and will act as a positive factor in local revitalization. Second, the urban regeneration areas and the control group were compared based on the business type of new start-up stores. As a result of the analysis, urban regeneration areas have a high proportion of industries targeting the active population, not residents. This will promote local activation by attracting the daytime population. Third, the urban regeneration areas and the control group were compared based on the diversity of the business types of newly established stores. As a result of the analysis, urban regeneration areas in metropolitan cities will induce multipurpose shopping for consumers as stores selling different products are concentrated. On the other hand, urban regeneration areas in small cities will induce consumers to compare shopping as stores selling similar products are concentrated.
