  • The mobile medical service has been operated for many years by a number of medical schools and hospitals as a most convenient means of medical service delivery to the people residing in such area where the geographical and socioeconomic conditions are not good enough to enjoy modern medical care. Despite of official appraisal showing off simply with numbers of outpatients treated and medical persons participated, however, as well recognized, the capability (in respect of budget, equipment and time) of those mobile medical teams is so limitted that it often discourages the recipients as well as medical participants themselves. In the midst of rising need to secure medical service of good quality to all parts of the country, and of developing concept of primary health care system, authors evaluated the effectiveness of and problems associated with mobile medical servies program through the community diagnosis of a village (Opo-myun, Kwangju-gun) to obtain the information which may be halpful for future improvement. 1. Owing to the nationwide Sae-Maul movement powerfully practiced during last several years, living environment of farm villages generally and remarkably improved including houses, water supply and wastes disposal etc. Neverthless, due to limitations in budget time and lack of knowledge (probably the most important), these improvements tend to keep up appearances only and are far from the goal which may being practical benefit in promoting the health of the community. 2. As a result of intensive population policy led by the government since 1962, there has been considerable advances in understanding and the rate of practicing family planning through out the villages and yet, one should see many things, especially education, to be done. Fifty eight per cent of mothers have not received prenatal check and the care for most (72%) delivery was offered by laymen at home. 3. Approximately seven per cent of the population was reported to have chronic illness but since only a few (practically none) of the people has had physical check up by doctors, the actual prevalence of chronic diseases may reach many times of the reported. The same fact was observed also in prevalence of tuberculosis; the patients registered at local health center totaled 31 comprising only 0.51% while the numbers in two neighboring villages (designated as demonstration area of tuberculosis control and mass examination was done recently) were 3.5 and 4.0% respectively. Prevalence rate of all dieseses and injuries expereinced during one month (July, 1977) was 15.8%. Only one tenth of those patients received treatment by physicians and one fifth was not treated at all. The situation was worse as for the chronic patients; 84% of all cases either have never been treated or discontinued therapy, and the main reasons were known to be financial difficulty and ignorance or indifference. 4. Among the patients treated by our mobile clinic, one third was chronic cases and 45% of all patients, by the opinion of doctors attended, were those who may be treated by specially trained nurses or other paramedics (objects of primary care). Besides, 20% of the cases required professional managements of level beyond the mobile team's capability and in this sense one may conclude that the effectiveness (performance) of present mobile medical team is quite limitted. According to above findings, the authors would like to suggest following for mobile medical service and overall medicare program for the people living in remote country side. 1. Establishment of primary health care system secured with effective communication and evacuation (between villages and local medical center) measures. 2. Nationwide enforcement of medical insurance system. 3. Simple outpatient care which now constitutes the main part of the most mobile medical services should largely be yielded up to primary health care unit of the village and the mobile team itself should be assigned on new and more urgent missions such as mass screening health examination of the villagers, health education with modern and effective audiovisual aids, professional training and consultant services for the primary health care organization.

  • 본 연구에서는 발아에 따른 유색미(흑광), 거대배아미(큰눈, 수원595호), 고아밀로스 쌀(고아미4호) 현미의 이화학적 특성, 취반 및 식감 특성, 전분 특성 변화를 조사하였다. 현미밥의 수분흡수율, 부피팽창율, 용출고형물 함량은 모든 품종에서 유의적으로 증가하였다. 발아에 따른 수분흡수율 및 용출고형물 함량 증가는 수침시간과 조리시간을 단축시키기 때문에 현미의 취반특성을 개선하고 이용성을 증진시킬 것이다. Tensipresser로 측정된 식감특성에서 발아는 현미의 경도와 부착성을 감소시키고 탄력성과 찰기를 증가시켰다. 이는 현미의 거친 식감이 발아함에 따라 부드러운 식감으로 변화되었음을 의미한다. 발아함에 따라 현미의 호화점도는 급격하게 감소하였지만, 호화개시 온도는 변하지 않았다. 아밀로스 함량이 높은 고아미4호는 발아에 따른 점도 감소가 다른 품종에 비해서 작았다. 발아에 따른 아밀로스 함량 및 아밀로펙틴 분자사슬분포의 일괄된 변화는 관찰하기 힘들었으나 일부 품종에서 유의적인 차이가 있었다. 발아에 따른 현미의 이화학적 특성 및 식감 특성의 변화는 발아 동안 활성화되는 효소에 의한 고분자 화합물의 분해, 발아 후 건조과정에서 발생하는 낟알 표면의 균열에 의한 것으로 생각된다. 이와 같은 결과는 발아가 현미의 식감과 취반특성을 개선할 수 있는 효과적인 방법임을 증명한다.

  • 농어촌 등에서 소규모로 발생하는 하수를 자연정화공법 의한 인공습지에서 효과적으로 처리하기 위하여 소형 하수처리장치를 호기성조 및 혐기성조로 구분하여 시공한 다음, 최적 하수 부하량을 조사하기 위해 하수 부하량별 오염물질의 처리효율을 조사한 결과 호기-혐기 조합형 소형 하수처리장에서 전반적으로 하수 부하량이 증가함에 따라 오염물질의 처리효율이 점점 감소하는 경향으로 특히 하수부하량 300 $Lm^{-2}day^{-1}$ 이상에서 수처리효율의 감소폭이 약간 컸다. 따라서 본 소형 하수처리장에서 BOD, $COD_{Mn}$, 탁도, T-N 및 T-P를 안정적으로 처리하기 위한 최적 부하량은 300 $Lm^{-2}day^{-1}$ 이었고, 이 때의 방류수 중 BOD, $COD_{Mn}$, 탁도, T-N 및 T-P의 처리효율은 각각 99, 94, 99, 49 및 89%로 현행 방류수 수질기준을 만족하면서 안정적으로 처리되었다. 하지만 본 소형 하수처리장에서 방류수 중의 T-N 및 T-P 함량은 각각 $28.5{\sim}29.4$$0.9{\sim}2.1mgL^{-1}$ 정도로서 앞으로 질소와 인의 방류수 수질기준이 각각 20 및 2 $mgL^{-1}$로 강화됨에 따라 보다 안정적인 수처리를 위해서는 T-N 및 T-P 처리효율을 향상시켜야 할 것으로 판단된다. 이에 최적 하수 부하량하에서 질소와 인의 강화될 방류수 수질기준(질소 20 $mgL^{-1}$ 및 인 2 $mgL^{-1}$)을 만족시키면서 안정적인 하수처리를 위한 최적의 수처리 공정개선 방안을 조사하였다. 호기-혐기 조합형 소형 하수처리장에서 수처리 공정개선 중 질소 및 인의 처리효율 향상이 가능한 방안은 혐기성조의 깊이 및 여재 입경 변경과 여재에 굴패각을 혼합한 방법이었다. 혐기성조의 깊이 및 여재 입경 변경 조건 중 혐기성조 1.5 m 깊이에서 여재 A(유효입경 1.50 mm)를 사용한 경우 T-N 및 T-P의 처리효율을 각각 10 및 3% 향상시켰고, 여재에 굴패각 혼합한 경우 T-N 및 T-P의 처리효율을 각각 14 및 7% 향상시켰다. 또한 동일한 조의 체적하에서 혐기성조의 깊이를1.5 m로 깊게한 것은 혐기성조 깊이 1 m에 비해 부지면적을 약 33% 정도 감소시킬 수 있을 것으로 판단되며, 또한 굴패각을 사용한 것은 폐기물의 재활용면에서도 매우 효과적인 방안으로 사용될 수 있을 것으로 판단된다.

  • 본 연구는 국내 4대강 유역에 조성된 수변녹지를 대상으로 탄소의 저장 및 연간 흡수를 계량화하고, 수변녹지의 탄소저감 효과를 증진하기 위한 조성방안을 모색하였다. 표본 선정한 40개소 연구 대상지의 녹지구조 및 식재기법은 흉고직경이 평균 $6.9{\pm}0.2cm$이고 식재밀도가 $10.4{\pm}0.8$주/$100m^2$로서, 소형 수목의 저밀 단층식재로 대표된다. 식재수목에 의한 단위면적당 탄소의 저장량과 연간 흡수량은 각각 평균 $8.2{\pm}0.5t/ha$, $1.7{\pm}0.1t/ha$/년이고, 식재밀도가 높을수록 증가하는 경향을 보였다. 토양의 유기물함량과 단위면적당 탄소저장량은 각각 $1.4{\pm}0.1%$, $26.4{\pm}1.5t/ha$이었다. 대상지의 수목과 토양은 1ha당 약 61kL의 휘발유 소비에 상당하는 탄소량을 저장하고, 수목은 해마다 1ha당 3kL의 휘발유 소비에 기인한 탄소배출량을 상쇄하는 효과를 나타냈다. 이 탄소저감은 식재 후 5년 이상~10년 미만 생장한 효과로서 식재수목의 생장과 더불어 훨씬 더 증가할 것으로 예측된다. 연구 대상지와 상이한 식재기법의 조성모델들을 선정하여 향후 30년 동안 수목생장에 따른 연간 탄소흡수량의 변화를 비교 시뮬레이션하였다. 그 결과, 경과년도별 누적 탄소흡수량은 식재규격이 더 크고 식재밀도가 더 높은 다층 군식의 생태식재모델에서 저밀 단층식재인 대상지보다 10년 및 30년 경과시 각각 약 1.9배, 1.5배 더 많았다. 수변녹지의 탄소저감 효과를 증진하기 위해서는 규격이 상대적으로 큰 수목을 혼식하는 다층 군식, 속성수를 포함하여 연간 생장률이 양호한 자생수종의 중 고밀 식재, 식재수종의 정상적 생장에 적합한 토양조건 구비 등이 요구된다. 본 연구결과는 조성 초기단계인 수변녹지 사업에서 수질보전 및 생물서식에 부가하여 탄소흡수원의 역할을 제고하기 위한 실용적 지침이 될 것으로 기대한다.

  • 목 적: 이중선원 듀얼에너지 CT(DS-DECT)의 가상 단색 영상을 이용해서 영상의 질 향상과 선량학적 영향에 대한 방사선치료계획 이용의 유용성을 평가하고자 한다. 대상 및 방법: DS-DECT를 이용하여 듀얼에너지(80/Sn 140 kVp)와 싱글에너지(120 kVp) 영상을 획득하였다. 영상 교정 팬텀 실험을 위해서 40-140 keV 범위로 단색 영상을 재구성했다. 선량 측정용 고체물등가팬텀 연구에서는 64, 69, 88, 105 keV 단색 영상을 선택했다. 스테인리스 스틸을 포함한 고체물등가팬텀에 $10{\times}10cm^2$ 조사야, SSD 100 cm, 10 MV 광자선, 100 MU 조사선량, 단일빔으로 치료계획을 수립하였다. 방사선량측면도 자료는 중심축에 위치한 4개의 지점에서 구했다. 싱글에너지 CT에서 획득한 다색 영상을 기준영상으로 하고, 가상 단색 영상의 선량학적 결과를 분석하였다. 결 과: 낮은 단색 에너지 수치에서 평균 감약이 증가했다. 7개의 물질 중에서 Teflon이 에너지 의존성이 가장 컸고, 10 keV 수치 상승으로 CT number가 평균 2.48 % 감소했다. 저밀도 공기에서는 단색 에너지에 대한 에너지 의존성이 없었다. Polystyrene, Acrylic은 70 keV 이상에서 안정한 CT number를 나타내었다. CT-ED 변환 곡선은 80 keV 단색 영상과 120 kVp 다색 영상이 비슷하였다. 단색 영상의 에너지가 증가할수록 금속의 식별 능력이 향상되었다. 줄무늬 인공음영은 105 keV 단색 영상에서 높은 감소를 보였지만, 여전히 남아 있었다. 다색 영상과 비교하여 각 영상에 따른 방사선치료계획의 선량학적 차이는 ${\pm}0.7%$ 미만이었다. 결 론: 듀얼에너지 영상의 획득은 싱글에너지에 비해 피폭선량을 감소시킬 수 있고, 가상 단색 영상은 CT number 보정에 유용하였다. 향상된 영상의 질은 인체의 기하구조 묘사와 전자 밀도 분포 형성에 도움이 될 것으로 사료된다.

  • 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.
