Animal feedstuff handling is one of the major fugitive dust sources in the port of Incheon. For the effective control of fugitive dusts emitting from the port of Incheon, dust control facilities with bag filter systems should be designed properly considering the characteristic of the fugitive dusts including those from animal feedstuffs. The ultimate goal of this study is thus to develop the optimum fugitive dust control system which will be applicable for the renovation of the port. As the first step to achieve this longstanding goal, filtration characteristics of soybean shell, the largest dust sources in the port, were investigated with the specially designed filter testing apparatus for this study. The variables tested for the experiments included filter materials, dust concentrations, relative humidities, and filtration velocities. Also, the filtration characteristics of the other animal feedstuffs such as sunflower seed shell, tapioca, and palm shell were investigated to determine $K_2$ as a function of filtration velocity. The information on $K_2$ will be used to design the optimum bag filter systems for animal feedstuffs handling in the port.

The idea of the school networks for joint venture and use of school facilities is forming and using an organic network of schools that will communally share a group of facilities that are uniquely appropriate for each schools. Focused on two prominent cities of Northern Choongnam province, Cheonan and Asan city, the objective of this study is to present and exhibit the plans for joint venture and use of school facilities, and to use them as an example for other provincial cities within the nation where such renovation may be possible. The school networks is proposed based on units of 1 km radius around each site, that is named as small school network, in order to ease the communal use of the sidewalks by the residents and the facilities by the nearby schools. In Cheonan city, six small school networks were proposed, which will supply three to four elementary schools for an average of 50,000 people. On the other hand, Asan city, which showed shortages of elementary schools, three small school networks including the middle and high schools in addition to the elementary schools were proposed, that will provide three to six schools for an average of 30,000 people.

Instead of brilliant advancement of the organ transplantation in the medical fields, laryngeal transplantation still has couple of problems to be solved before trial on human. Among them functional restoration of the implanted larynx is the most important point. Recent advancement in animal model studies showed possibility of solving the main problem. Eighteen cases of canine laryngeal transplantation in mongrel dogs were done in this department. One cranial artery and two external jugular veins were connected. External and internal branches of the superior layngeal nerve and anterior and posterior branches of the recurrent laryngeal nerve were connected individually. Only two dogs have lived longer than 4 weeks(4weeks, and 10 1/2weeks) and they died unfortunately due to asphixia caused by obstruction of the cannula. Thirteen dogs only lived five days through 15 days. The main causes of the failure were obstruction of the connecting vein, pharyngocutaneous fistula and the wound infection. Although the result was not good enough to evaluate the functional restoration of the implanted larynx, the implanted larynges from the two dogs lived longer than minimum criteria of long term survival(4 weeks) were relatively good in shape at the time of autopsy. This program will be continued after renovation of the animal lab. facilities.

The study in the fild of medical instrument has been out of the interest by any of the life scientist in Korea. Especially, the recent developments in the medical electromics are remarkable one. Authors planned this study to ascertain the possibility of setting up the thermister thermometer with available accessories of demestic prouducts including some specific foreign assembly parts. By proper use of the thermister as one of the wheatstone bridge, we could detect tile resistance variations due to the environmental temperature variace. The intensive care for the bridge circuit and compensation scheme was required. The calibration procedure adopted here makes it possible to read the current as the temperature. The temperature range was determined by the examination and construction of the graph of the resistance-temperature variation. The determination of electric current, available ambient-temperature, the reduction of excessive current and self-heating of the thermister were made. Renovation in response-velocity was under taken too. This electronic thermometer was designed and assembled by the circuitry developed in accordance with the maximum availability of domestic products with some foreign-made parts. The result of our experiment showed very stable function and proved to be the most promissing item in the actual application as long as the thermistor thermister is concerned.

Geographic Information has been used widely for landuse and management, city plan, and environment and disaster management, etc., But geographic information has been built for individual cases using various methods. Therefore, the discordancy in data, double investment, confusion of use and difficulty of decision supporting system have been occurred. In order to solve these problems, national government is need to framework database. This framework database was enacted for building and use of National Geographic Information System and focused on basic plan of the second national geographic information system. Also, the framework database was selected of eight fields by NGIS laws and 19 detailed items through meeting of framework committee since 2002. In this research, The 19 detailed items( road, railroad, coastline, surveying control point etc.,) of framework database consider a Priority order, In the result of this research, the framework database is obtain to a priority order for building and the national government will carry effectively out a budget for the framework database building. Each of 19 detailed items is grouping into using the priority order of the framework database by AHP analysis method and verified items by decision tree analysis method. The one of the highest priority order items is a road, which is important for building, continuous renovation, and maintain management for use.

This experiment was undertaken to determine the effect of pasture ages on the total production and seasonal yield trends, botanical composition and forage quality of pasture mixtures. This experiment was conducted at the Livestock Experiment Station, RDA, Suweon. The results obtained were as follows : 1. Total dry matterDM) yield of pasture mixtures was the highest in the first year, and thereafter no significant reduction in the 2nd through the 4th year, but decreased by 30% in the 5th year. 2. The 34.4% of total DM yield was produced at the first cut, and decreased from then on. Total DM yield of pasture mixtures varied by year and climatic facton. In 1992, Total DM and TDN yields of pasture mixtures were 13.4 and 8.5 IvlT/ha, respectively. 3. The content of crude protein(CP), in virro DM digestibility(IVDMD) and TDN of pasture mixtures were 12-14, 70-80, and 62-65%, respectively. The highest forage quality was obtained at the 4th cutting. 4. The botanical compositions of legumes and weeds were increased as the year of establishment advanced, and highly increased at the 3rd cut after summer growth. 5. Based on the results of this study it appears that economic forage production could be expended to the 4th year with proper management, and the special renovation techniques may be needed for maintenance of pasture yield from the 5th year.

This study aims to propose the comprehensive evaluation of performance multi-family housing. Most of the existing studies for the reproduction have evaluated by the safety of structure. Therefore those pass over the functional factors which is important for the evaluation of residential qualities. This study represents that the reproduction renovation should not be secured the safety of structure but established the quality of lift. And questionnaire asking expert's opinion also supplemented. As a result, the item for examination and the weight for evaluation are suggested in functional deterioration. The results of this study are summarized as follows: 1. Existent redevelopment criteria are not appropriate to decide the environmental comfort, the vital function of housing and the residential management finance. 2. The future criteria have to evaluate the existing environmental comfort, be reconstructed to put first general deterioration. 3. Evaluation elements was extracted throughout the document research, evaluation elements analysis system was separated in residential area, suburb of dwellings, community, and housing complexity environmental assesment, 4. Each category of influence ratio was extracted to assess total deterioration throughout the expert question survey. 5. Each category analysed (1) $0{\sim}30%$: function is good (unnecessary to improve) (2) $31{\sim}40%$: average (necessary of partial improvement) (3) $41{\sim}59%$: bad (necessary of total improvement) (4) $60{\sim}100%$: the worst (unable to improve throughout the repair)

With old housing being renovated in both the Gatdui and Daean areas, of the Gyeongju downtown area, this study was carried out to examine the implications of various renewal approaches in a city that is rich in both history and culture. The study included a physical survey of the areas under construction as well as a questionnaire given to residents to analyse their level of satisfaction with and requirements for housing and their preferring housing types. The study also analysed renewal patterns among the residents were analysed by examining the ways in which particular renovations had been performed. The findings showed that both governmental authorities and private parties need to be involved and work together if such renewals are to be successful. In recent years there have been regular conflicts between those in favor of development and those in favor of preserving the historic and cultural resources of the city. At times the city identity has been neglected by residents. In the future, it will be necessary to take both development conditions and the residents' economic situations into consideration when making decisions about renewal and to consider a wide range of methods for rearranging housing patterns, with the goal of transforming housing renovation into a broader program of social rearrangement for the purpose of improving social patterns in the city.
