장포자충(Thelohanellus kitauei) 포자의 극사탈출 여부를 생사 각정 기준으로 하여 물리 화학적 요인이 포자의 활성 및 생존에 미치는 영향에 대하여 관찰하였다. 신선 포자를 0.45% 및 0.9% 생리식염수와 증류수에 현학시켜
우리나라는 지형과 기후가 복잡다양한 데다가 하절기에는 필리핀 남양군도로부터 상습적으로 불어오는 태풍의 진로권내에 위치해 있고 년간 강우량의 대부분이 벼 재배기인 하절기에 집중적으로 내리는 관계로 이때 강우와 강풍이 단독 또는 동반하여 갖가지 풍수해양상을 일으킨다. 풍해는 조풍해, 건조풍해 및 강풍해로 구분하여 볼 때 조풍해(염풍해)는 1986년 8월 28~29일 태품 Vera호 내습시 남부 해안지방 일대에서는 강우가 그치면서 염분을 함유한 초속 6m정도의 강풍이 불어 해안으로부터 2.5km까지 도체 조기에 염분을 건물당 1.1~17.2mg 부착시켜 심한 조풍해를 일으켰다. 그리고 건조풍해는 '87년 이래로 내습한 대부분의 태풍들이 4.0~8.5m의 태풍이 남부 및 동해안에 불어 Foenhn 현상으로 건조풍이 되고 이때 출수기에 처한 벼 이삭은 심한 백수피해와 변색위피해를 받았다. 태풍해로서는 풀수기 이전의 벼 생육단계에서 경엽이 기계적으로 절상, 파열, 고사되고, 등숙기에는 도복과 탈입이 심하게 된다. 풍해경감은 태품 내습을 회피하도록 8월 15일까지 출수시키고 풍해저항성이 비교적 강한 상풍벼와 청청벼 재배가 효과적이다. 한편 수해로서는 농경지 유시, 이몰, 침관수 및 도복 등을 들 수 있으나 각종 Dam, 제방축조, 하구언공사 등으로 피해는 많이 줄었지만 국지적 집중호우나 강변유역 제방내의 내수로 인한 침관수나 도복피해는 상습적으로 일어난다. 핌관수해는 태풍과 다우가 주로 8월 말경에 내습하여 2~4일 정도 도체가 관수된다. 이따 남부 특수만식답의 벼생육단계는 생육초중기에 해당되므로 어린 생육단게일수록 피해가 크고 보통식세어는 생식생장기에 해당되므로 유수나 팬이삭은 불념이 되더라도 죽은 이삭을 갖는 경의 상위절로부터 재생경이 나와 정상이삭으로 되어 수량 감소가 가장 튼 감수분열기 피해에서도 66%의 수량보상력을 갖게 된다. 침관수피해 경감을 위해서는 사전적 조처로서 관수저항성 및 백엽고, 벼멸구, 도복저항성을 갖는 품종을 선택 재배하는 것이 효과적이다. 특히 통일형 품종은 일본형 품종에 비하여 관수시 모든 생육단게에서 관수저항성이 강한데 묘생존율이 높고, 엽신과 엽초의 이상신장력이 낮아 퇴수시 기술적 장해가 적으며 생식생장기에는 근활력, 광합성능력이 높아 피해회복이 빠르고 고위절분얼이삭에 의한 수량보상력이 높다. 이상을 종합하여 볼 때 풍수해를 최소화하기 위해서는 다음과 같은 연구가 금후 이루어져야 할 것이다. \circled1 기상예보, 풍수해 피해실태 및 그로 인한 작황 등의 원격탐사 및 전산화에 의한 분석 연구가 이루어져야 하고, \circled2 품수해와 관련된 불량환경에서 내성을 갖는 품종 육성 보급이 이루어져야 하고, \circled3 품수해 발생상습지에서는 벼 피해를 보상할 수 있는 타작물과의 함리적 작부체계 개선 연구가 이루어져야 하고, \circled4 피해도체의 활용도 증진 연구가 이루어져야 할 것이다.
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.
