본 연구에서는 브라질 서부의 Mato Grosso do Sul 주의 위치하는 장가다. 쟈마이카 두 개의 농장에 유칼리나무 인공조림블록단지를 위한 식재계획을 세워 보았다. 우선 위성사진을 분석하고 GIS에 의해서 현상태대로의 토지이용구분 및 산림식생구분을 하였고 이것을 기초로 하여 조림가능 지역을 계산하였다. 그리고 농장주인의 요구에 따라 조림가능지역에 대한 식재계획을 3차년도까지 수립하였다. 두 개의 농장 총면적은 5,301ha이며 조림가능면적은 3,913ha로서 전체면적의 74%에 해당하는 것으로 추정되었다. 그리고 나머지 26%에 해당하는 1,388ha의 면적은 산림법상 영구보존시켜야 할 산림식생 면적으로 추정되었다. 토양손실을 최소화하기 위해서 등고선에 따라 구획한 조림블록은 1년차에 27개 블록으로 총 1,308.8ha에 이르고, 2년차에도 27개 블록에 1,327.4ha, 그리고 3년차에는 30개 블록에 1,276.5ha의 면적으로 구획되었다.

This report describes the first prize design of Midongsan Eco-park, which is located in Chungcheongbuk-do (North Chungcheong) province. Criteria of the winning design are as follows: 1) The design should include a neighborhood park as well as a portion of a green zone, in order to harmonize the area ecosystem, gradually assimilate the surroundings, and serve as an education tool for the public. 2) According to an analysis of area maps and a site-inspection, a preserved area, a buffer area, a restored area, and a developed area should be developed. In the buffer and restored areas, major facilities and activity spaces should be set up. 3) Observation trails should be accessible to visitors, and a variety of adventure programs should be available. 4) The eco-park should be designed to provide a habitat for the Gorani (Chinese water deer) which used to live around Midongsan. 5) For sensuous and vivid visitor experiences, diverse programs are to be designed to accommodate different seasons, visitor ages, and required time. Environment and eco-education are to be emphasized to maximize the effect of the eco-programs. 6) Optimal activities for visitors of different ages, optimal time intervals and eco-programs by age are also suggested. 7) Facilities are zoned into three sections according to level of development. Each section has a main area and supplementary areas for better understanding. 8) Nature-friendly arrangement of facilities and construction should minimize earthwork and adverse effects on the local ecology. Throughout the planning, the following things were learned: longer-term analysis including all season's observation is essential; planning, designing, bui Iding and managing should be based on this careful, extended observation. The contest should have taken plate over a longer period of time in order enable more detailed planing of the eco-park For improved management and activities, a volunteer system in linked with schools eco-institutions and NGOs should be developed with eco-interpreters.

최근에 활발히 진행된 ITS사업과 신호개선사업으로 인해 신호제어 시스템의 온라인화와 실시간 신호제어시스템이 도입되어 교통신호제어기의 첨단화가 진행되었다. 하지만 실시간 신호제어 운영변수 산정의 기초가 되고, 현재 가장 일반적으로 이용되는 신호교차로의 제어방법으로 사용되는 TOD제어의 운영을 위한 효과적인 신호시간계획을 위한 방법론이 부재되어 왔다. TOD 시간계획의 최적화를 수행하는 과정은 신호교차로의 효율성 제고를 위해 매우 중요한 작업이며, 최적화 수행과정의 정립이 필요한 실정이다. 본 연구에서는 TOD 시간계획 작성 시 가장 선행되어야 할 Sub Area 결정 방법과 첨두시와 비첨두시의 시간 경계를 결정하는 방법론에 대해서 정의하고, 각 방법론에 의해 결정된 시간경계 구간의 신호제어 변수를 신호최적화 모형을 통해 산출하였다. 최적화된 신호제어 변수의 효과를 분석하기 위해 서울시의 동2로 간선도로 구간에 새로운 TOD 시간계획을 적용하고 필드테스트를 수행하였으며, 이러한 TOD 시간계획의 적용 효과를 사전/사후 분석을 통해 검증하였다.

The population of small yellow croaker, Larimichthys polyactis, in the Yellow and East China Seas has decreased significantly since the mid 1970s. Several management measures have been introduced to conserve it, but population size remains low. To rebuild this population, it is now necessary to consider more effective management methods based on the stock assessment. To determine long-term population changes, fishery and biological data collected over 34 years (1969-2002) were analysed. Yearly fish length compositions were analysed for the time periods 1968 through 1970, 1978 through 1982, and 1993 through 2002; and catch data was available from 1969 to 2002. Annual population sizes were calculated based on length composition, the relationship between total length and body weight, and total landings. Analyses showed that since the 1970s, average size of harvested fish decreased; the proportion of less mature fish (smaller than the 50% maturity length, 19cm) in catches has increased and the estimated biomass has decreased significantly. Consequently, the main management recommendation is that juvenile fish need to be better protected to allow the rebuilding of resources to a more sustainable population level. This will require fish size limit, permissible mesh size, and closed area and season regulations.

Despite the intensive family Planning program of the government, which has reduced the :average population growth to 2.0 percent in 1970, the continuing high fertility rates and poor family planning services in urban slum areas has been continually pointed out by various evaluation seminars. Thus, it was felt that a study of the current status of family planning in an urban slum population was needed. The aims of the study were to: (1) delineate the general characteristics of the urban slum population (2) discover the knowledge, attitudes, and practice of family planing. (3) determine what was felt to be the ideal number of children. (4) determine the status of induced abortion. A random stratified sample of 200 women was selected from a population of 3, 118 married women, 20-49 years of age, living in the Yonsei Community Health Project area and registered at the Yonhee Community Health Service Institute. The respondents were interviewed by the investigates, using a pretested questionary, from the period of October 1 to October 30, 1972. The findings of the Study were as follows: 1. Afore than half of the respondents were in the high fertility age group (25-34): of lower educational level (under primary School) : from rural areas: and with unstable sources of income. 2. The average respondent had 3.6 living children. 3. Most of the respondents had knowledge of contraceptive methods such as the Loop(78, 5%) and Oral pill (87.0%). 4. Seventy seven percent of the respondents recognized the Health Center as an available source for family planning. 5. About seventy percent of the respondents approved of family planning. 6. Eighty four point five percent of all the respondents answered that using contraceptives is harmful to maternal health. 7. Currently, 21.0 percent of the respondents were using contraceptives, while 40.0 percent of the respondents were current users or had used contraceptives. 5. Of the respondents who had ever stopped using contraceptives, 78.0 percent gave side effects as the reason they discontinued the method. 9. The average number of ideal children reported by the respondents was 3.5. 10. If they had only 2 daughters, 85.5 Percent of the respondents thought they must have more children. 11. Sixty nine point five percent of the respondents approved of induced abortion for unwanted pregnancies, while 34.5 percent of the respondents had experienced induced abortion for unwanted pregnancies. The mean number of induced abortion for unwanted pregnancies was 0.7. 12. The result of this study showed that such urban slum population would be one of the most important target of the family planning services, therefore further social-psychological researches with technical development on this area are recommended.
