  • 본 연구는 라오스에 소재한 전형적인 농 산촌 마을을 선정하여, 마을 단위를 대상으로 생산구조를 전환할 경우의 소득증대에 대한 경제적 타당성을 분석하였다. 대상지는 라오스 쌍퉁구에 위치한 농부아 마을로써 산림지역이 혼재된 논농사 위주의 마을이다. 이 마을이 취할 수 있는 소득 제고 전략은 단기적으로 손쉽게 소득을 제고할 수 있는 작목으로 노니(Morinda citrifolia)가 꼽힌다. 사업 기간은 20년으로 가정하고, 1ha 면적에 $3m{\times}3m$ 간격으로 식재한 총 1,100본을 대상으로, 묘목 생존율과 노니 수매가격에 따라 시나리오 1, 2, 3을 구분하였다. 일반적으로 노니는 생장이 좋은 편이나, 본 연구에서는 생산 경험 부족, 병충해 등의 리스크를 감안하여 기본 시나리오 1을 묘목 생존율(=열매 생산량)을 기존 자료(하와이)보다 보수적으로 설정하였다. 시나리오 1은 노니 묘목의 생존율이 1년생이 50%, 2년생이 60%, 3년생부터 20년생까지 70%로 유지된다고 가정하였다. 시나리오 2는 묘목 생존율이 10%씩 감소되어 40%, 50%, 60%로 제약을 두었고, 시나리오 3은 묘목생존율이 10% 감소되고, 노니 수매가격 또한 10% 감소된 경우로 가정하였다. 이러한 조건하에 라오스 시장 할인율 10%를 기준으로, 3개 시나리오 모두 IRR이 각각 24.81%, 19.02%, 16.30%로 모두 경제성이 있음이 확인되었다. 또한 ha당 B/C도 각각 시나리오 1, 2, 3에 대해서 할인율 10%를 기준으로 모두 1.71, 1.47, 1.31로 분석되었다. 분석결과는 향후 농부아 마을은 대체 작목(노니)를 통한 저소득 영농구조를 탈피할 수 있는 좋은 계기가 될 것을 시사하며, 각종 정부 및 민간 투자사업을 계획할 때 수행하는 사전진단 절차 단계에서 유용한 의사결정 정보로써 활용이 가능하다.

  • In this study, to take the object of this thesis on understanding the characteristics on marketing structure and marketing distribution of landscape materials after consideration in the side of prices trends which is important factors for analysis in understanding the market of landscape materials. To do this, Analysis is divided into the prices trends. The investigation of prices trends and marketing distribution are to collect data refer to purchases and sales reports, these results are used to analyzed the operative factor of forming market structure. The periodic range of this thesis is limited from 1996 to 2000 and analytic articles is limited on 609 landscape materials(planting materials : 567 articles, facility materials : 7 articles, the other : 35 articles). The results of the whole prices trends and marketing distribution survey can be summarized as follows : 1. Prices trends of showing 3 types of landscape materials : In cases of planting, facility and the others materials, the annual average increasing rate of the index number of price was 3.1%, 3.4%, 3.1% while the KPRC(Korea Price Research Center) price was 3.98% for the past five years. 2. GSP(Government Specified Prices) Prices trends of showing 3 types of landscape materials : In cases of planting, facility and the others materials, the annual average increasing rate of the index number of price was 3.7%, 1.2%, 2.6% while the KPRC(Korea Price Research Center) price was 3.98% for the past five years. This increase indicates a small price margin, particularly, the GSP price of planting materials should be adjusted to a realistic level. 3. Native and exotic product Prices trends of showing 3. types of landscape materials : In cases of Native planting, facility and the others materials, the annual average increasing rate of the index number of price was 3.2%, 3.2%, 3.6% while cases of exotic was 3.1%, 1.0%, 5.8% for the past five years. The index number increase of prices of exotic landscape materials were fluctuated more than those the native landscape materials.

  • The Korean government announced a national mid-term target to reduce 30% of greenhouse gas (GHG) emissions from business-as usual (BAU) level by 2020 in a voluntary and independent manner. In this study, we examined the $CO_2$ mitigation potential and conducted an economic effect analysis of green living actions in households in Korea. We also proposed some ways to implement green life to achieve the national target. If green lifestyle takes root in households nationwide, $CO_2$ emission would be reduced to 27.3% of the emission in 2007. This would save the country about 4.93 trillion won per year and each household could save about 300,000 won per year, which accounts for about 0.5% of GDP (as of 2007). Considering the five-year plan for green growth to invest 2% of GDP in green growth every year, this would not only reduce the economic burden on households, industries and the country but also increase economic growth potential by reinvesting the saved resources into green growth. Heating and lighting would be the greatest contributor to GHG mitigation of green life in the residential sector. It means we could achieve the national goal by reducing unnecessary heating and lighting and using energy-saving electric home appliances. The implementation of green living actions would reduce a significant amount of greenhouse gas emissions, ultimately relieving the burden on businesses to reduce GHG emissions. And it is one of the most cost-effective mitigation tools in order to achieve the mid-term GHG mitigation goal.

  • In September 1974, a survey was conducted towards 900 women respondents, each representing a household, residing in 18 selected Myuns(townships) of 18 Guns(counties) in Kyunggi-Do. Fifty households were selected randomly in each Myun and the sample Myuns were also randomly selected from the 18 Guns home-visiting interviews were carried out by Myun level maternal and child health workers with questionnair forms designed to measure the maternal and child health status at each household. Major findings obtained from this survey can be summarized as follows: 1. Of the women responents who were investigated in this survey, 13.1% of them were comprised in the illiterates, indicating no difference in literacy rate from that in most urban areas. 2. Most(93.8%) of the respondents were found to have married at ages of 20-24 years old. 3. Most(85.8%) of the respondents were found to have delivered their first babies at ages of 20-24, while only 13.4% had their first babies at 25-29. 4. About 22% of the respondents had 2 children, while 19% and another 19% had 2 and 4 children, respectively. 5. A great majority of the respondents (78%) experienced not a single death of a child within the family, while about 17% experienced death of one child. 0.7% of the women experienced deaths of 4 or more children. 6. 18% and 17% of the women experienced 4 and 3 pregnancies, respectively, and 12% of them experienced 7 or more pregnancies. 7. About 29% of the women experienced an induced abortion at least once. Nearly 2% of them were found to have experience of 4 or more induced abortions. 8. One half (51%) of the women were found to have received prenatal guidances in the latest pregnancies by (Ub(town) and Myun (township) level maternal and child health workers at least once or more times. 9. 52% women received professional prenatal care in the latest pregnancies: 24% at hospitals or clinics and 20% at health centers. 10. Most (89%) of the last-born children were delivered at home, while only 8.7% were delivered at hospital or clinics. 11. Materials used at delivery comprise vinyl (40%), cement bags (32%) ana gauzed or absorbent cottons (19%). 12. The largest preportion of the attendants at delivery comprises mothers in-law (48). Only 24% were found to be attended by either doctors, midwives or maternal and child health workers. 13. In most (90%) of the deliveries scissors were used to cut the umbilicus. But most (7%) of them used unsterilized scissors, 6 while only 20% of them used sterilized ones. 14. About 68% of the last-born babies were breast-fed for 12 months or more. Those who weaned during 6-12 months were 21%. 15. During 12 months after birth, 65% of the last-born babies were breast-fed, while 24% were given a combination of breast milk and cooked rice. 16. About nine out of the 10 births were found to be registered. 17. 71% of babies received BCG vaccination, while 79% and 56% received samllpox and DPT vaccinations, respectively within a year after birth. Those who were vaccinated against poliomyelitis were about 50%. 18. About 87% of the respondents recogninized the existence of government-sponsored maternal and child health guidance program.

  • The demand for livestock and poultry products including beef, pork, chicken, egg and milk whose income elasticities are relatively higher than other staple foods, has been increased significantly during the past two decades in response to the remarkable increase in per capita GNP. This trend will be continued during the fifth and the sixth five year economic development plan period beginning with 1982. The annual GNP growth rate will be 7.5% on the average during the next 10 years. It is greatly needed to estimate the demand for beef, pork, chicken egg and milk and to study the feasibilities of domestic production of livestock products for the formulation of adequate policies in order to equate the consumption and the production during the 1980s. So this study reviewed the possible changes in the food consumption patterns during the 1980s, estimated the demand for beef, pork, chicken, egg and milk by using empirical demand functions and finally made suggestions for the formulation of long term price stabilization policies for each livestock, poultry and dairy products through the equilibrium of the quantity of demand for and supply of the products. There are many factors affecting the demand for meats, but this study considered own price, prices of supplements and substitutes and per capita income as the independent variables in the demand equations. It was found that it's own price and income were most significantly affecting factors among others and the degree of substitution effects were remarkably different among the products. According to the meat demand derived in this study, per capita consumption of beef, pork and chicken in the base year 1982 was 11.2kg for total meat, 2.5kg beef, 6.0kg pork and 2.5kg chicken, 106 pieces egg, 15.1kg milk respectively, while those in 1991 were 19.3kg for total meat, 4.8kg beef, 9.6kg pork, 4.9kg chicken, 133pieces egg and 44.1kg milk. It is also predicted through this study that, when the level of production costs be maintained, the domestic production of pork and chicken will meet the demand for them during the fifth and sixth five year economic plan period. However, there will be chronic shortage of beef supply during the coming years. The annual import requirement will be 30,000tons to 40,000tons during the period. In order to stabilize the domestic livestock and poultry and dairy products market, the government should introduce measures to curb the increase in beef consumption by encouraging the consumption of pork and chicken. For this, the livestock production policy measures should be concentrated on : 1) the improvement of infrastructures of beef production by introducing advanced feeding and management technology, subsidies for the establishment of facilities and price support programs for farmers : 2) the development of dairy beef : 3) the reinforcement of the forecast systems for pork and chicken production and consumption.

  • In order to ascertain the attitudes of residents to their health and the National Health Promotion Law, surveyors interviewed 1,220 subjects, 1% of men and women in Kyungsan city, who were twenty-year-old or more. The major findings are as follows: Men and women were 48.2% and 51.8%, respectively. The recognition rate of enacting and enforcing this law is 59.2% of men and 51.3% of women. With regard to the behavioral attitude to the health in the distinction of sex and age, current smokers are 31.2% of the interviewees, 61.6% of the men and 3.3% of the women. Current drinkers are 35.1%, 59.5% of the men and 12.3% of the women, but on the other hand there is little significance in the distinction of age. The acknowledgement proportion of enacting and enforcing this law is 59.2% of male and 51.3% of female. In terms of the recognition rate of the contents according to the general characteristics of interviewees, it appears that the indication of a warning expression on a packing paper of cigarette case and a liquor bottle is 92.4% and also the designation of a smoking free area in public facilities is 94.8%. Prohibition of cigarette-sale to the teenagers who are under 19, is 96.0%. Considering these facts, the recognition rate is high. On the contrary, 48.8% is accounted for encouraging a medical check-up before marriage which is in a low position. As a result of multiple behavior as a independent educational level, marital significant variables. In case of having undergone a periodic medical examination the recognition rate was high whereas frequent exercise led to the low recognition rate. Concerning the details of the undertaking in accordance with each factor of general characteristics, the greater part of them have been appraised successfully whether it is recognized or not. On the other side, no effect got answered about the result of the undertaking subjects to general and peculiar behavior attitude towards health was in effect or not. A great majority approved of more reinforcement of legal regulation about smoking and drinking regardless of whether they perceived the details of the law of promotion of National Health Promotion Law or not. Additionally there was significant difference in reinforcing legal regulation of smoking and drinking in compliance with the attitude of the substance of this law. With regard to education, public relations and evaluation about national health through public health centers by our government, the younger and the higher in education they are, the more deficient they feel. First of all, those who were aware of the enforcement of this law as well as plenty of scarcity answered that better service of disease prevention had to be expanded than ever. In consideration of the above-stated results, the education to public health and the business of public relations should be reinforced and a practical campaign for health life should also spread out for the purpose of encouraging to practise healthy life-style.

  • The purpose of this study was to compare the different environment among the young children of large and small cities and rural areas in Korea, in order to know how these different environment have an effect on the children's intellectual and emotional development. For this subjects, 2,700 questionares with 51 items were distributed to the infants' mothers in each area to interview and answer. About 1,800 questionaires were gathered from 3 metropolitan, 6 cities and 6 rural areas in (each 2 farming, fishing and mining villages) The results of analyzing these questionaires were like following; 1. The average number of children of each family was 2.5 in large cities, 3.0 in small cities and 3.6 in the rural areas. 2. White about 75% of infants' parents of large cities graduated college education, only 6% of the rural parents did it. Most infants' parents of the rural areas have only graduated the elementary school. 3. About 90% of the rural, small and large cities family have had radios and T.V sets, and 90% of infants watched T.V program for 2 hours a day in average. 4. While about 50% of large cities' young children were not reared by their mother's milk but by milk and other foods, about 95% of rural infants by breasting mills. 5. Young children of large cities were wearing about 5 months earlier than those of the rural. 6. While 20% children of cities were taught in the kindergarten, most children of the rural areas could not be taught in the kindergarten. 7. About 45% young children of the rural areas and cities were understood and taught reading, writing letters and numbers by their parents, brothers and sisters before entering primary school. 8. While 50% young children of large cities have had pianos and were taught music in kindergarten or piano tutor's, most of the rural areas have not had pianos and could not be taught music. 9. Most children's favorite music songs were T.V signals or C.M songs in both the rural and cities. 10. While most children of cities have had lots of children's pictures or fairy tale books. most infants of the rural areas have had nothing or a few. 11. As lots of infants could not find their pleasure resorts of sport tools outside, they used to play in side streets or publicroads with their friends. 12. While most infant's parents in cities wanted to make their infants lawyer or medicine doctor, most parents in rural areas wanted to make their children teacher or technician. 13. About a half of Korean infants have had their own rooms or have lived in it together with their brother or sister. In conclusion, as children of large cities have had more various kinds of cultural circumstances than the rural areas in aspects of cultural institutions' tools and environment of their parents' education, books, toys, pleasure resorts and their own rooms, the intellectual development of the former could be considered to surpass those of the latter. In other words, the average IQ points of urban's young children are 10 point higher than those of the rural areas, which means the better circumstance would affect the infant's intellectual development. Therefore, the government must support to make good circumstances of the children in the rural areas.

  • 2014년말 기준 항공레포츠 동호인은 약 13만명, 경항공기 356대, 경량항공기 200대, 초경량비행장치 636대에 이르고 있으며, 항공레포츠 산업은 향후 생활수준 향상에 따라 급격히 발전할 유망 레저산업으로 부상하고 있다. 또한 초경량비행장치, 특히 무인비행장치를 활용한 사용사업도 지속적으로 증가하는 추세에 있으며, 향후 이들 장치를 활용한 관광, 레저 사업자 서비스에 대한 수요도 증가할 것으로 전망된다. 본 논문은 경항공기, 경량항공기 및 초경량비행장치 관련 지속적인 수요 증가에 대비하여 경항공기, 경량항공기 및 초경량비행장치 산업 활성화를 위한 "경(소형)비행장 개발의 표준화"를 통한 개발 방안에 대한 연구를 목적으로 하였다. 정부에서 제시하고 있는 항공레저산업의 활성화를 위해서는 전국에 경비행장을 많이 건설하여 운영할 수 있는 인프라를 제공해야 하지만, 각 지자체와 기관들은 앞 다투어 경항공기 비행장 건설에 나서고 있으나, 현실적으로 개발이 된 곳은 많지 않다. 정부차원에서도 경비행장 입지를 위한 연구를 진행한 바 있으나, 후보지만 검토하였고, 실제 건설에 대한 타당성을 수행하고 있지 못하다. 만일 실제로 건설이 된다면, 이러한 비행장의 입지가 과연 적합한지에 대해서는 타당성 검토를 통해 다시 한 번 검증 받게 될 것이다. 그리고 기존 연구보고서들과 관련 문서를 통해 입지선정 요소를 도출해내고, 전문가의 설문을 통해 경비행장의 입지선정 요소들을 분석해 내고자 하였다. 연구모형은 AHP분석을 위해 계층화 형태로 정하였는데, 선행연구 검토를 토대로 가중치를 정하여, 경비행장 입지선정요소에 대하여 2단계 구성을 기술/운영적 요소, 경제/정책적요소로 선정하였다. 그리고 3단계로 기술적 요소, 운영적 요소로 구성하였다. 마지막 단계로는 총 11개 (기상조건, 장애물 제한표면 조건, 공역조건, 운항절차, 소음문제, 환경문제, 시설의 이용성, 건설 및 투자비용, 지역경제 기여도, 접근성, 산업연계성)의 하위요소들을 선정하여 구성하였다. 경항공기 비행장 입지선정 요소 가중치 설문은 본 분야의 전문가 집단인 항공 운항, 관제 등의 교수 및 기장, 교관, 관제사, 정비사 등 전문가 70명을 대상으로 실시하였다. 일관성 지수는 CI=0.02로 일관성이 있는 것으로 나타났다.
