  • 최근 몇년동안 식물은 빌딩 실내디자인의 필수적인 요소가 되었다. 서울시 대형건물 28개소를 대상으로 실내조경식물의 활용실태에 관한 연구에서 다음과 같은 몇가지의 사항을 알 수 있었다. 1. 우리나라 대형건물에서 재배되고 있는 식물의 층은 Dracaena속, Monstera속, Philodendron속, Schefflera속, Washingtonia속의 순으로 나타났다. 2. 품종별로는 몬스테라(페루투사 종), 쉐프렐라 홍콩, 와싱토니아 야자, 관움죽, 디펜바키아(하와이 스노우 종) 순으로 나타났다. 3. 실내식물은 대부분이 관엽식물로 99.5%를 차지 하였다. 4. 덩굴성식물은 모두 9품종으로 나타났는데 헤데라(피트스버그 종) 에피프레늄은 지피식물로 군식으로 식재되어 가장 많이 이용되었고, 다음이 옥스카르디움, 신고니움(마크로필럼 종) 순으로 나타났다. 5. 실내식물의 대부분이 프라스틱분을 사용하였으며, 배치형태는 바닥이 전체 58%를 차지하고, 실내정원과 선반위에 배치한 것이 각각 19%, 18%를 나타내었다. 6. 실내식물의 초장은 50cm 이내가 51%를 차지하고 50cm-2.8m가 43%를 차지하였으며, 가장 초장이 긴 것은 카나리아 야자로 4m로 측정되었다. 7. 실내의 조도가 500Lux 이하로 측정된 건물이 43%나 되어 식물이 정상적인 생장을 위하여 인공조명을 필요로 하고, 인공조명을 설치함으로서 화분을 교환하는 번거로움을 피할 수 있을 것이다. 8. 대형건물에서의 실내식물의 구입목적은 탐방객을 위한 것이 88%로 나타났다. 9. 관리자들의 식물재배형태는 화분 받침대를 이용하는 것을 가장 선호하였다. 10. 실내에서 식물생장을 위해 가장 중요한 환경요소는 광과 조도, 수분이었다.유되어 있었으며 당분은 함유되어 있지 않았다.무는 3.2m일 때 10년후에는 30%가, 4.2m일 때 20년 후에 30%가 겹치게 되며, 백목련의 경우는 3.3m일 때 10년 후에 30%가 겹치며, 4.2m 일 때 30%가 겹치는 것으로 나타났다. 따라서, 10년 후까지는 수종간에 차이가 없으나 20년 후를 고려하면 느티나무의 식재간격은 다소 넓어져야 한다고 생각된다.수행하고 있기 때문에 다양한 행동의 설명력있는 이유로 볼 수 없다.때로는 민담에서도 풍수가 주제가 되는 경우가 있고, 일반적으로는 역사적 사실이나 인물을 통하여 취락민이지녀온 자연요소에 대한 인식관 또는 그러한 생활에서 나타나는 윤리관 등이 암암리에 표현되기도 한다. 민담을 통하여 우리는 주민들 의식 속에 남아있는 취락의 중요한 요소나 장소들을 찾아볼수 있고 더불어 이들을 중심으로 이루어 졌을지도 모를 생활모습들을 생각해볼 수 있다. 이러한 것들은 $\ulcorner$순응$\lrcorner$의 다른 일면 또는 때에 따라서는 극히 의도적인 $\ulcorner$표현$\lrcorner$적인 한 면모 - 그 대표적인 경우로 정원을 구성하는데 개재된 인간의 의미는 무언가를 표현 또는 표출하고자 함에 있다는 점 -라 볼수도 있을, 예로써 성리학적 사고관념으로써 집과 정사 그리고 주변 경관을 자신의 내적본직 또는 윤리적 영역으로 삼아 묘사.표현.구체화 시켜가기도 한다. 최소한 동족부락의 한두 예들에서 그러한 $\ulcorner$표현$\lrcorner$적 의도에 의한 경관구성의 일면을 확인할수 있지만 엄밀히 생각하여 보면 이러한 예의 경우도

  • 한국과 인도네시아를 포함한 대부분의 국가는 온실가스 감축을 위해 바이오디젤 같은 바이오연료 보급에 대한 강력한 정책을 추진하고 있다. 하지만, 바이오디젤 보급 확대를 위해서는 원료 부족 문제를 먼저 해결해야 한다. 본 연구에서는 원료 공급 안정성을 개선하고 바이오디젤 생산 가격을 낮추기 위해 비식용이면서 동시에 단위면적당 생산성이 높은 인도네시아 열대작물(R. Trisperma) 오일의 바이오디젤 생산 가능성을 조사하였다. 수확기간이 다른 두 종류의 오일은 많은 불순물과 높은 유리지방산 함량을 가지고 있어 효율적인 바이오디젤 생산을 위해, 에스테르화 반응과 전이에스테르화 반응을 실시하였다. 오일은 반응을 진행하기 앞서 여과와 수분제거 과정을 통해 반응의 효율을 높이고자 하였다. 에스테르화 반응은 불균질계 산 촉매인 Amberlyst-15를 사용하였으며, 반응 전 오일들의 산가는 각각 41, 17 mg KOH / g이었으나, 에스테르화 반응 후 3.7, 1.8 mg KOH/g으로 약 90% 이상의 전환율을 보이며 유리지방산 함량을 2%이하로 감소시켰다. 이후 전이에스테르화 반응은 KOH를 염기 촉매로 사용하여 바이오디젤 합성 실험을 진행하였다. 생성된 바이오디젤은 약 93%의 FAME 함량을 나타냈으며, 총 글리세롤의 함량은 0.43%으로 제품 규격(FAME 96.5%, 총 글리세롤 0.24%)에는 미달되었다. 이는 지방산 조성 분석 결과 일반적으로 관찰되지 않는 특이 지방산인 ${\alpha}$-Eleostearic acid가 10.7~33.4% 포함되어 나타나는 특성으로 판단되며, 추가 반응 최적화 및 분리정제 연구 진행으로 연료품질 규격 달성이 필요한 것으로 나타났다. 기존에 활용되지 못하던 비식용 원료로부터 바이오디젤 생산 기술을 확보할 경우 바이오디젤 보급 확대를 위한 안정적 원료 공급에 기여할 것으로 판단된다.

  • 21세기는 '문화경쟁' 시대라고 말해도 과언은 아니다. 국제화 시대를 살아가고 있는 오늘날 우리는 '자국의 정체성'을 문화에서 찾으려 한다. '문화'란 그 민족이 살아온 발자취를 고스란히 담고 있는 자국민의 독특한 민족성을 말한다. 세계는 하나의 다차원적인 지구로 변해가는 이 시점에서 민족적 고유성과 독창적 조형성을 담은 전통 문양은 자국민을 대표하는 브랜드다. 프랑스의 명품 브랜드 고야드 문양은 수작업 과정에서 자연스럽게 생성된 Y자형 패턴을 볼 수 있다. 이 문양은 160년이 지난 오늘날 프랑스를 대표하는 기업 브랜드로 세계적인 명성을 자랑한다. 반면 저소득국가의 경우 직물을 직조하는 과정에서 자연스럽게 만들어진 문양은 민족적 고유한 미의식으로 계승되어 지구촌 사람들로부터 사랑받고 있다. 이처럼 다차원적인 세계를 살아가는 지구촌 사람들은 자국의 문화를 계승하려는 의지와 타민족의 고유한 문화를 보존하려는 이른바 '지구는 하나라는 시각(One Planet Perspective)' 프레임 워크를 실현하고자 한다. 예를 들어 콜롬비아의 '와유 부족'은 2013년 식수난으로 국제 구호기구들이 이들을 찾아가 구호품을 전달하는 과정에서 핸드메이드 제품인 '모칠라백'을 발견하게 된다. 이것이 계기가 되어 유럽과 한국에서도 이를 수입하여 판매를 결정한 것은 '와유 부족'의 생계에 도움을 주고자 함이다. 또한 소수 부족의 전통문화 속에서 천 년 동안 진화해 온 미적·문화적 가치는 유네스코에 등재되어 세계적으로 보존되고 있다. '문화란 하루아침'에 형성된 것이 아니라 적어도 100년 이상 지속되면서 그 시대의 트렌드에 적용된 문양은 기업을 대표하는 브랜드다. 또한 나아가 국가 정체성을 반영한 문양은 민족적 고유한 미의식으로 계승되기도 한다. 우리는 민족적 고유한 미의식을 계승하고 있으나 이를 현대적인 추세에 맞게 창의적이고 심미적으로 재해석한 실용적 가치를 보여주는 전통 문양 브랜드는 없다. 이에 본연구는 세계의 문양 브랜드 전략을 파악하고 한국 기업 브랜드의 문제점을 제시하고자 한다.

  • 키리바시를 포함한 태평양 도서국가들은 기후 변화, 지하수 오염 및 식생 변화로 인한 해수면 상승 및 해안 침식으로 인해 생활 공간의 감소 뿐만 아니라 필수 자원 부족으로 고통받고 있다. 이러한 문제를 해결하기 위한 글로벌 활동은 SDGs 이행을 위한 UN의 노력으로 진행되고 있다. 태평양 도서 국가들이 풍부한 해양 자원을 이용하여 기후 변화에 대응하고 적응할 수 있도록 모색해 왔다. 즉, 해수 플랜트는 이러한 태평양 도서 국가에서 SDG # 14를 기반으로 SDG #2, #6 및 #7을 달성하는 데 도움을 줄 수 있다. 선박해양플랜트연구소(KRISO)는 2016년에 설립한 지속가능 해수이용 아카데미(SSUA)를 통해 키리바시 SSUA협회를 결성하고, 해양수산부(MOF)의 해양수산 ODA사업으로 키리바시에 해수플랜트를 지원하였다. 키리바시 SSUA협회는 해수 및 태양에너지를 이용하는 해수플랜트를 이용하여, 2018년부터 2020년까지 지역 사회에 식수와 채소를 공급하는 공익사업을 하고 있다. 역량강화 과정을 통해 키리바시 SSUA협회는 기술 이전을 받았고, 지역사회에 수경재배 시스템의 설치, 모종과 비료 보급, 재배관리 기술지도 및 모니터링을 실시하였다. 협회는 3년 동안 140여 가구에 수경재배 시스템(일부는 태양광발전 패널 제공)을 보급하고, 다양한 채소를 재배하여 자가 소비 또는 판매하게 하였다. 또한, 태양광발전 연계 해수담수화 시스템을 설치하여 식수를 공급하도록 하고 있다. 만족도 조사를 통해 대부분의 수혜 가구가 만족하였고, 주변 지역 및 도서로 보급확산을 희망하고 있음을 알 수 있었다. 따라서, 키리바시 SSUA협회는 공동체 이용 및 관리 체계화를 지원하는 자활사업을 추진할 계획이며, 이러한 활동은 태평양 도서국가들의 SDGs 달성을 지원하기 위한 ODA 프로그램으로 확산될 수 있을 것이다.

  • I. Subject of the study A study on the nutritive value and utilization of powdered seaweeds. II. Purpose and Importance of the study A. In Korea the shortage of food will be inevitable by the rapidly growing population. It will be very important study to develop a new food from the seaweeds which were not used hitherto for human consumption. B. The several kinds of seaweeds have been used by man in Korea mainly as side-dishes. However, a properly powdered seaweed will enable itself to be a good supplement or mixture to certain cereal flours. C. By adding the powdered seaweed to any cereals which have long been staple foods in this country the two fold benefits; saving of cereals and change of dietary pattern, will be secured. III. Objects and scope of the study A. Objects of the study The objects will come under four items. 1. To develop a powdered seaweed as a new food from the seaweeds which have been not used for human consumption. 2. To evaluate the nutritional quality of the products the analysis for chemical composition and animal feeding experiment will be conducted. 3. Experimental cocking and accepability test will be conducted for the powdered products to evaluate the value as food stuff. 4. Sanitary test and also economical analysis will be conducted for the powdered products. B. Scope of the study 1. Production of seaweed powders Sargassum fulvellum growing in eastern coast and Sargassum patens C.A. in southern coast were used as the material for the powders. These algae, which have been not used for human consumption, were pulverized through the processes of washing, drying, pulverization, etc. 2. Nutritional experiments a. Chemical composition Proximate components (water, protein, fat, cellulose, sugar, ash, salt), minerals (calcium, phosphorus, iron, iodine), vitamins (A, $B_1,\;B_2$ niacin, C) and amino acids were analyzed for the seaweed powders. b. Animal feeding experiment Weaning 160 rats (80 male and 80 female rats) were used as experimental animals, dividing them into 16 groups, 10 rats each group. Each group was fed for 12 weeks on cereal diet (Wheat flour, rice powder, barley powder, potato powder, corn flour) with the supplementary levels of 5%, 10%, 15%, 20% and 30% of the seaweed powder. After the feeding the growth, feed efficiency ratio, protain efficiency ratio and ,organs weights were checked and urine analysis, feces analysis and serum analysis were also conducted. 3. Experimental cooking and acceptability test a. Several basic studies were conducted to find the characteristics of the seaweed powder. b. 17 kinds of Korean dishes and 9 kinds of foreign dishes were prepared with cereal flours (wheat, rice, barley, potato, corn) with the supplementary levels of 5%, 10%, 15%, 20% and 30% of the seaweed powder. c. Acceptability test for the dishes was conducted according to plank's Form. 4. Sanitary test The heavy metals (Cd, Pb, As, Hg) in the seaweed powders were determined. 5. Economical analysis The retail price of the seaweed powder was compared with those of other cereals in the market. And also economical analysis was made from the nutritional point of view, calculating the body weight gained in grams per unit price of each feeding diet. IV. Results of the study and the suggestion for application A. Chemical composition 1. There is no any big difference in proximate components between powders of Sargassum fulvellum in eastern coast and Sargassum patens C.A. in southern coast. Seasonal difference is also not significant. Higher levels of protein, cellulose, ash and salt were found in the powders compared with common cereal foods. 2. The levels of calcium (Ca) and iron (Fe) in the powders were significantly higher than common cereal foods and also rich in iodine (I). Existence of vitamin A and vitamin C in the Powders is different point from cereal foods. Vitamin $B_1\;and\;B_2$ are also relatively rich in the powders.'Vitamin A in ·Sargassum fulvellum is high and the levels of some minerals and vitamins are seemed4 to be some influenced by seasons. 3. In the amino acid composition methionine, isoleucine, Iysine and valine are limiting amino acids. The protein qualities of Sargassum fulvellum and Sargassum patens C.A. are seemed to be .almost same and generally ·good. Seasonal difference in amino acid composition was found. B. Animal feeding experiment 1. The best growth was found at.10% supplemental level of the seaweed Powder and lower growth rate was shown at 30% level. 2. It was shown that 15% supplemental level of the Seaweed powder seems to fulfil, to some extent the mineral requirement of the animals. 3. No any changes were found in organs development except that, in kidney, there found decreasing in weight by increasing the supplemental level of the seaweed powder. 4. There is no any significant changes in nitrogen retention, serum cholesterol, serum calcium and urinary calcium in each supplemental level of the seaweed powder. 5. In animal feeding experiment it was concluded that $5%{\sim}15%$ levels supplementation of the seaweed powder are possible. C. Experimental cooking and acceptability test 1. The seaweed powder showed to be utilized more excellently in foreign cookings than in Korean cookings. Higher supplemental level of seaweed was passible in foreign cookings. 2. Hae-Jo-Kang and Jeon-Byung were more excellent than Song-Pyun, wheat cake, Soo-Je-Bee and wheat noodle. Hae-Je-Kang was excellent in its quality even as high as 5% supplemental level. 3. The higher levels of supplementation were used the more sticky cooking products were obtained. Song-Pyun and wheat cake were palatable and lustrous in 2% supplementation level. 4. In drop cookie the higher levels of supplementation, the more crisp product was obtained, compared with other cookies. 5. Corn cake, thin rice gruel, rice gruel and potato Jeon-Byung were more excellent in their quality than potato Man-Doo and potato noodle. Corn cake, thin rice gruel and rice gruel were excellent even as high as 5% supplementation level. 6. In several cooking Porducts some seaweed-oder was perceived in case of 3% or more levels of supplementation. This may be much diminished by the use of proper condiments. D. Sanitary test It seems that there is no any heavy metals (Cd, Pb, As, Hg) problem in these seaweed Powders in case these Powders are used as supplements to any cereal flours E. Economical analysis The price of the seaweed powder is lower than those of other cereals and that may be more lowered when mass production of the seaweed powder is made in future. The supplement of the seaweed powder to any cereals is also economical with the criterion of animal growth rate. F. It is recommended that these seaweed powders should be developed and used as supplement to any cereal flours or used as other food material. By doing so, both saving of cereals and improvement of individual's nutrition will greatly be achieved. It is also recommended that the feeding experiment for men would be conducted in future.

  • 급격한 도시화를 겪으면서 자연적인 물순환 체계의 왜곡을 초래하였다. 이러한 물순환 구조의 변화는 기존 수자원 이용 경향을 변화시키며 하천 건천화 현상을 유발하고 있다. 이를 관리하기 위해 건천화 평가 및 예측이 가능한 하천 건천화 영향 평가 기술이 필요하다. 하천 건천화 영향평가 기술 수행을 위해서는 기초자료로써 GIS 기반의 공간자료 구축이 필수적이나, 관련 연구는 미흡한 실정이다. 따라서 본 연구에서는 하천 건천화 평가를 위한 GIS 기반의 시계열 공간자료 활용에 대한 연구를 수행하였다. 이에 6개 하천 건천화 영향요소(기상, 토심, 산림밀도 및 높이, 도로망, 지하수 이용량, 토지이용)을 대상으로, 과거 수십년 간의 변화과정을 전국 단위 GIS 자료로 구축하여 연속수문모형 운용에 대한 기초자료로 활용하였다. 이러한 영향요소를 대상으로 시계열에 따라 하천 건천화 원인을 분석하고 해석할 수 있는 분포형 연속수문모형 기반의 DrySAT을 활용하여 하천 건천화 영향요소별 연유출량 및 건천화 평가를 수행하였다. 그 결과, 다른 요소들은 고려하지 않고 주어진 기상 조건하에 연유출량은 기본값 977.9mm로 산출되었다. 반면, 토심 감소, 산림 높이 증가, 도로 개발 증가, 지하수이용량 증가, 토지이용 개발변화를 고려하였을 때의 연평균 유출량은 각각 1,003.5mm, 942.1mm, 961.9mm, 915.5mm, 1003.7mm로 산출되었다. 산출된 결과는 하천건천화의 주요 원인으로서 지표유출량을 증가시켜 하천유량을 감소시키는 토심의 감소, 지표유출량을 감소시키는 산림 밀도의 증가, 지표하유출량을 감소시키는 도로의 증가, 기저유출량을 감소시키는 무분별한 지하수 개발과 지하수이용량의 증가, 지표유출량을 증가시키는 불투수지역의 증가를 들 수 있다. 또한, 하천 건천화 정의 및 등급 범위를 통해서 건천화 등급에 따라 표준유역별로 나타내었으며, 기상, 토심 감소 고려, 산림 높이 증가, 도로 개발 증가, 지하수이용량 증가, 토지이용 개발변화를 고려하였을 때의 건천화 등급은 각각 2.1, 2.2, 2.5, 2.3, 2.8, 2.2로 나타났다. 기본값인 강우조건을 제외한 5개 하천 건천화 영향요소에 대한 건천화 영향순위는 지하수 이용량 변화에 대한 건천화 영향이 제일 컸으며, 산림 밀도 변화, 도로 건설 변화, 토지이용 변화 및 토심 변화 순으로 나타났다. 향후 전국 하천 건천화 평가시스템 개발을 통해 6개 하천 건천화 영향요소에 대한 미래 자료 변화 및 이에 대한 건천화의 진행전망 등 시스템에 의한 평가결과를 토대로 맞춤형 하천 건천 관리 및 방지 방안을 제공할 수 있을 것으로 판단된다.

  • Today most developed countries provide modern medical care for most of the population. The rural area is the more neglected area in the medical and health field. In public health, the philosophy is that medical care for in maintenance of health is a basic right of man; it should not be discriminated against racial, environmental or financial situations. The deficiency of the medical care system, cultural bias, economic development, and ignorance of the residents about health care brought about the shortage of medical personnel and facilities on the rural areas. Moreover, medical students and physicians have been taught less about rural health care than about urban health care. Medical care, therefore, is insufficient in terms of health care personnel/and facilities in rural areas. Under such a situation, there is growing concern about the health problems among the rural population. The findings presented in this report are useful measures of the major health problems and even more important, as a guide to planning for improved medical care systems. It is hoped that findings from this study will be useful to those responsible for improving the delivery of health service for the rural population. Objectives: -to determine the health status of the residents in the rural areas. -to assess the rural population's needs in terms of health and medical care. -to make recommendations concerning improvement in the delivery of health and medical care for the rural population. Procedures: For the sampling design, the ideal would be to sample according to the proportion of the composition age-groups. As the health problems would be different by group, the sample was divided into 10 different age-groups. If the sample were allocated by proportion of composition of each age group, some age groups would be too small to estimate the health problem. The sample size of each age-group population was 100 people/age-groups. Personal interviews were conducted by specially trained medical students. The interviews dealt at length with current health status, medical care problems, utilization of medical services, medical cost paid for medical care and attitudes toward health. In addition, more information was gained from the public health field, including environmental sanitation, maternal and child health, family planning, tuberculosis control, and dental health. The sample Sample size was one fourth of total population: 1,438 The aged 10-14 years showed the largest number of 254 and the aged under one year was the smallest number of 81. Participation in examination Examination sessions usually were held in the morning every Tuesday, Wenesday, and Thursday for 3 hours at each session at the Namchun Health station. In general, the rate of participation in medical examination was low especially in ages between 10-19 years old. The highest rate of participation among are groups was the under one year age-group by 100 percent. The lowest use rate as low as 3% of those in the age-groups 10-19 years who are attending junior and senior high school in Taegu city so the time was not convenient for them to recieve examinations. Among the over 20 years old group, the rate of participation of female was higher than that of males. The results are as follows: A. Publie health problems Population: The number of pre-school age group who required child health was 724, among them infants numbered 96. Number of eligible women aged 15-44 years was 1,279, and women with husband who need maternal health numbered 700. The age-group of 65 years or older was 201 needed more health care and 65 of them had disabilities. (Table 2). Environmental sanitation: Seventy-nine percent of the residents relied upon well water as a primary source of dringking water. Ninety-three percent of the drinking water supply was rated as unfited quality for drinking. More than 90% of latrines were unhygienic, in structure design and sanitation (Table 15). Maternal and child health: Maternal health Average number of pregnancies of eligible women was 4 times. There was almost no pre- and post-natal care. Pregnancy wastage Still births was 33 per 1,000 live births. Spontaneous abortion was 156 per 1,000 live births. Induced abortion was 137 per 1,000 live births. Delivery condition More than 90 percent of deliveries were conducted at home. Attendants at last delivery were laymen by 76% and delivery without attendants was 14%. The rate of non-sterilized scissors as an instrument used to cut the umbilical cord was as high as 54% and of sickles was 14%. The rate of difficult delivery counted for 3%. Maternal death rate estimates about 35 per 10,000 live births. Child health Consultation rate for child health was almost non existant. In general, vaccination rate of children was low; vaccination rates for children aged 0-5 years with BCG and small pox were 34 and 28 percent respectively. The rate of vaccination with DPT and Polio were 23 and 25% respectively but the rate of the complete three injections were as low as 5 and 3% respectively. The number of dead children was 280 per 1,000 living children. Infants death rate was 45 per 1,000 live births (Table 16), Family planning: Approval rate of married women for family planning was as high as 86%. The rate of experiences of contraception in the past was 51%. The current rate of contraception was 37%. Willingness to use contraception in the future was as high as 86% (Table 17). Tuberculosis control: Number of registration patients at the health center currently was 25. The number indicates one eighth of estimate number of tuberculosis in the area. Number of discharged cases in the past accounted for 79 which showed 50% of active cases when discharged time. Rate of complete treatment among reasons of discharge in the past as low as 28%. There needs to be a follow up observation of the discharged cases (Table 18). Dental problems: More than 50% of the total population have at least one or more dental problems. (Table 19) B. Medical care problems Incidence rate: 1. In one month Incidence rate of medical care problems during one month was 19.6 percent. Among these health problems which required rest at home were 11.8 percent. The estimated number of patients in the total population is 1,206. The health problems reported most frequently in interviews during one month are: GI trouble, respiratory disease, neuralgia, skin disease, and communicable disease-in that order, The rate of health problems by age groups was highest in the 1-4 age group and in the 60 years or over age group, the lowest rate was the 10-14 year age group. In general, 0-29 year age group except the 1-4 year age group was low incidence rate. After 30 years old the rate of health problems increases gradually with aging. Eighty-three percent of health problems that occured during one month were solved by primary medical care procedures. Seventeen percent of health problems needed secondary care. Days rested at home because of illness during one month were 0.7 days per interviewee and 8days per patient and it accounts for 2,161 days for the total productive population in the area. (Table 20) 2. In a year The incidence rate of medical care problems during a year was 74.8%, among them health problems which required rest at home was 37 percent. Estimated number of patients in the total population during a year was 4,600. The health problems that occured most frequently among the interviewees during a year were: Cold (30%), GI trouble (18), respiratory disease (11), anemia (10), diarrhea (10), neuralgia (10), parasite disease (9), ENT (7), skin (7), headache (7), trauma (4), communicable disease (3), and circulatory disease (3) -in that order. The rate of health problems by age groups was highest in the infants group, thereafter the rate decreased gradually until the age 15-19 year age group which showed the lowest, and then the rate increased gradually with aging. Eighty-seven percent of health problems during a year were solved by primary medical care. Thirteen percent of them needed secondary medical care procedures. Days rested at home because of illness during a year were 16 days per interviewee and 44 days per patient and it accounted for 57,335 days lost among productive age group in the area (Table 21). Among those given medical examination, the conditions observed most frequently were respiratory disease, GI trouble, parasite disease, neuralgia, skin disease, trauma, tuberculosis, anemia, chronic obstructive lung disease, eye disorders-in that order (Table 22). The main health problems required secondary medical care are as fellows: (previous page). Utilization of medical care (treatment) The rate of treatment by various medical facilities for all health problems during one month was 73 percent. The rate of receiving of medical care of those who have health problems which required rest at home was 52% while the rate of those who have health problems which did not required rest was 61 percent (Table 23). The rate of receiving of medical care for all health problems during a year was 67 percent. The rate of receiving of medical care of those who have health problems which required rest at home was 82 percent while the rate of those who have health problems which did not required rest was as low as 53 percent (Table 24). Types of medical facilitied used were as follows: Hospital and clinics: 32-35% Herb clinics: 9-10% Drugstore: 53-58% Hospitalization Rate of hospitalization was 1.7% and the estimate number of hospitalizations among the total population during a year will be 107 persons (Table 25). Medical cost: Average medical cost per person during one month and a year were 171 and 2,800 won respectively. Average medical cost per patient during one month and a year were 1,109 and 3,740 won respectively. Average cost per household during a year was 15,800 won (Table 26, 27). Solution measures for health and medical care problems in rural area: A. Health problems which could be solved by paramedical workers such as nurses, midwives and aid nurses etc. are as follows: 1. Improvement of environmental sanitation 2. MCH except medical care problems 3. Family planning except surgical intervention 4. Tuberculosis control except diagnosis and prescription 5. Dental care except operational intervention 6. Health education for residents for improvement of utilization of medical facilities and early diagnosis etc. B. Medical care problems 1. Eighty-five percent of health problems could be solved by primary care procedures by general practitioners. 2. Fifteen percent of health problems need secondary medical procedures by a specialist. C. Medical cost Concidering the economic situation in rural area the amount of 2,062 won per residents during a year will be burdensome, so financial assistance is needed gorvernment to solve health and medical care problems for rural people.
