The space for production, such as studios and control rooms, is a space for TV program production, which is the main function of broadcast. A block planning for such space should be carefully designed, because it can significantly affect the efficiency of production, as well as future productivity and the development and expandability of production. From the results of comparative analysis of 7 local terrestrial broadcasters built since the late 1990s, this study will. propose an ideal block planning for the future construction of local terrestrial broadcasters. Also, the results can be used a basic data when constructing new buildings for local broadcasters.

The main objective of modern reproductive technologies in pig reproduction is to increase reproductive efficiency and rates of genetic improvement. They also offer potential for greatly extending the multiplication and transport of genetic materials and the conservation of unique genetic resources in reasonably available forms for possible future use. The development and refinement of these technologies is concentrating on gamete and embryo collection, sorting and preservation, in vitro production of embryos, culturing, manipulation of embryos (splitting, nuclear transfer, production of chimeras, establishment embryo stem cells, and gene transfer) and embryo transfer. Also, the development of these novel technologies is facilitated by modern equipment for ultrasonography, microscopy, cryopreservation, endoscopy, and flow cytometry, microinjectiors, micromanipulators and centrifugation. The real impact on herd productivity will come from combining new reproductive techniques with powerful DNA technologies. The new reproductive techniques will allow a rapid turnover of generations, whereas the DNA technology can provide selection, which does not need phenotypic information when the selection decisions are made.

Beef and dairy cattle are the primary ruminant livestock in Korea, but there is a serious shortage of both fresh and dry forages. Small areas of forage crops or pastures, unfavorable soil and climatic conditions, high costs for pasture production, low establishment and management technologies, etc. are the main factors limiting roughage production in Korea. To meet the roughage demand of cattle several suggestions are presented. About 845,000 ha of hilly area could be developed for pastureland. Almost the same area of paddy field, and more than 200,000 ha of reclaimed land could be used for pasture production. If all the potential area is developed for pastureland, the area could be extended to 10 times more than is presently used for pasture crops and pastureland. Productivity would be increased by developing new technologies of establishment and management. Silvo-pastoral systems should be introduced to Korea.

The precast concrete column-beam structure, Green Frame, allows the main structural members such as precast concrete column and beam to be produced on the site, resulting in a reduction of transportation cost and the margin of plant. However, existing plywood from for in-situ production of precast concrete members has problems like putting in inordinate human resource, falling-off in quality and workability. To solve those problems, form system for in-situ production of precast concrete members shall be developed. In this regard, this study aims to analyze the structural concept of from system for in-situ production. The result of this study will use for development of form system for in-situ production.

The composite PC rahmen structure, called Green Frame, allows the main structural members such as PC column and beam to be produced on the site, resulting in a reduction of PC member transportation cost and the margin of PC plant (operation cost and profit), making it more economic than the bearing wall structure. To apply the Green Frame to practice, not only installation but also insitu-production process should be considered. Therefore, this study analyse the influence factors on insitu-production and installation schedule of composite precast concrete members. The results shall be used as basic criteria on the planning of insitu-production and installation of Green Frame.

The main purpose of this paper is to estimate environmental preference of advanced countries for water and air pollution. In doing so, we introduce home production. That is, we assume that pollution has not only negative effect on utility but also positive effect on production. Thus if the former is greater that the latter effect, the total effect of pollution is negative. In this paper, we investigated this effect of advanced countries by using GMM estimator. The main finding is that in case of air pollution. This effect is negative. This implies that in case of air pollution, the disutility effect is greater that productivity effect.

Objectives: The aim of this study is to analyze main problems on occupational safety and hygiene in construction sites and to suggest some improvement methods. In order to decrease industrial accidents, I emphasize the approach paradigm shifts according to characteristics of construction workers. Methods: Pointing out the irrationality of current institutions by comparing bad outcomes of occupational safety and hygiene in construction industry and characteristics of construction workers. Results: In order to decrease industrial accidents, we need some approach paradigm shifts; the supply method of industrial safety and health fundamentals on the construction industry level, the accident rate calculation by using the actual construction workforce instead of an estimation, institutionalizing the prevention efforts themselves for industrial accidents, securing enough production costs for the precondition of occupational safety and hygiene in construction sites. Conclusions: I ascertain the need of the approach paradigm shifts for decreasing industrial accidents in the construction industry.

Korean traditional Sikhye is made from rice and malt, and It's main product Is maltose. However commercial Sikhye differs from traditional Sikhye because it's main component is sucrose. Sikhye industry faces many problems such as contamination of malt with microorganisms, low amylase activity of malt and technical difficulties. There is no commercial Sikhye which is only using rice and malt by these reasons. To produce the traditional Sikhye free from these problems, it is necessary to restrict the microorganisms of malt and to standardize the amylase activity of malt. In addition, the Introduction of effective control and sanitaric process is required. In Sikhye production. if $\beta$-amylase and isoamylase or pullulanase were added, starch could be saccharified 100% as maltose. Accordingly, this method brings us the low cost of Sikhye.

This study compared the characteristics of consomme prepared by homeskill(Consomme A) and quantity food production skill(Consomme B) as well as by the main ingredients of Consomme. The highest portion of amino acids in Consomme was arginine, followed by glutamic acid and alanine. In sensory evaluation, Consomme A prepared with chicken meat and Consomme B with mixed beef & chicken were most preferred. This result showed that higher total amino acid content gave better sensory scores. There was a significant correlation between the turbidity of sensory evaluation and the color b value. Turbidity and viscosity of instrumental measurement were also significantly correlated.

This study has main purpose to understand and interpret the house Nok-U-dang, an upper class built in Chosun dynasty, not by outsider researcher's view but insider dweller's view. To interpret correctly, dweller's everyday life in the space and form is examined on a microscale beyond the physical space and form of the house, main object of architectural history To understand the present form exactly, the study restore traditional life in past era, 1940s. Main method of restoration is the ethnographic interview, based on cultural anthropology. Like any other upper-class house, the house has been influenced under ruling Confucian ideology in Chosun dynasty: separation of man's and woman's quarters and hierachical arrangement by generation, and worshipping ceremony for ancestor. However, it is by practical management for agricultural production that every court and building of the Noku-Dang can be explained correctly; preparing seed for sowing, tool storing, preparing and serving meal for laborers, making manure, harvesting, threshing grain, storing grain and so on. Precedent studies interpreted the house by the Confucian principle too much and made conclusion of dignity and austerity of ritual: woman's quarter, is closed and serene space. However this study shows that the space is semi-opened and composite space by agricultural works. And the Sarangchae, master's quarter, is located properly at visual center to control every agricultural activity.
