  • 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.

  • 목 적: 조기병기 유방암에서 유방보존수술 후 방사선치료 및 항암화학 병용요법이 보편화되면서 표준적치료로 인정되고 있다. 유방보존치료를 받은 환자들을 대상으로 수년 이내의 재발양상, 생존율 및 그에 관련되는 위험인자를 알아보기 위하여 본 연구를 시행하였다. 대상 및 방법: 1999년 1월부터 2003년 12월까지 관내상피암을 제외한 침윤성 유방암으로 유방보존수술 후 방사선 치료를 시행 받은 129명의 환자를 대상으로 후향적 분석을 시행하였다. 전체 환자의 중앙연령은 45세($27{\sim}76$세)이었고, 연령대로는 40대가 62명(48.1%)으로 가장 많았다. TNM 병기는 I기 65명(50.4%), IIa기 41명(31.7%), IIb기 13명(10.1%), IIIa기 9명(7.0%), IIIc기 1명(0.7%)이었다. 액와림프절 전이가 있었던 환자는 32명(24.8%)이었다. 수술은 사분원절제술이 115명(89.1%), 종괴절제술이 14명(10.9%)에서 시행되었다. 액와림프절곽청술은 120명(93%)에서 시행되었다. 방사선치료는 동측 전체 유방에 6 MV X-선으로 50.4 Gy를 28회에 걸쳐 시행하고, 원발병소에 $9{\sim}16\;Gy$를 추가하였다. 쇄골상 림프절 방사선치료를 받은 환자는 30명(23.3 %)이었다. 항암화학요법은 대부분 CMF요법으로 $4{\sim}6$회가 시행되었다. 전체환자의 중앙 추적관찰기간은 50개월($17{\sim}93$개월)이었다. 결 과: 5년 생존율은 96.9%, 5년 무병 생존율은 93.7%이었다. 병기별 5년 생존율은 I기 97.1%, IIa기 100%, IIb기 84.6%, III기 100%이었고, 5년 무병생존율은 I기 96.8%, IIa기 92.7%, IIb기 76.9%, III기 100%이었다. 유방내 국소재발은 2명(1.6%)에서 발생하였고, 동측 쇄골상 림프절 재발이 1명(0.8%), 원격전이는 5명(3.9%)에서 발생하였다. 국소재발의 평균 기간은 32.5개월이었다. 원격전이는 평균 21개월에 발생하였고, 골전이 3명, 간전이 1명, 전신전이 1명이었다. 이 중 2명이 각각 17개월, 25개월에 사망하였다. 예후인자 분석에서 병기만이 단변량 분석에서 유의하였다. 본 연구에는 III기 환자가 10명 포함되었는데, 원발병소의 크기는 모두 3 cm 이하였으며, 액와림프절 전이가 4개 이상인 경우였다. 이들은 모두 액와부 및 쇄골상부 방사선치료를 받았으며, 추적기간 동안 국소재발이나 원격전이 소견은 발견되지 않았다. 부작용으로는 10명(7.8%)에서 무증상방사선폐렴이 있었으며 증상을 동반한 방사선 폐렴이 1명(0.8%) 그리고 상지부종이 10명(7.8%)에서 있었다. 결 론: 추적기간이 짧았지만 조기 병기 침윤성 유방암에서 유방보존수술 후 방사선치료 및 항암화학요법을 시행하여 높은 국소 제어율과 생존율을 얻었으며, 향후 장기적인 추적관찰이 필요할 것으로 사료된다. 유방내 국소 재발은 수년 내에는 적었으며, 원격전이는 상대적으로 일찍 발생함을 알 수 있었다. 또한, 원발병소의 크기가 3 cm 이하로 작고, 액와림프절 전이가 4개 이상인 환자를 대상으로 유방보존치료 적용가능 여부에 대한 장기적 추적관찰 및 추가적 분석이 필요할 것으로 사료된다.

  • 기업연상(corporate association)이 제품 평가(product responses)에 어떻게 영향을 미치는 가에 대한 연구가 부진하다는 Brown and Dacin(1997)의 문제 제기가 있은 후, 기업연상이 제품 판단에 미치는 영향과 과정에 대한 조절변수와 매개변수들을 파악하려는 연구가 진행되어 왔다. 본 연구에서는 기업연상의 두가지 유형인 CA(corporate ability) 연상과 CSR(corporate social responsibility) 연상이 성능과 재무위험에 미치는 영향력과 그 영향력을 조절하는 변수들을 조사하였다. 분석 결과에 의하면, 주효과(main effects)에 있어서는, 가설에서 기대한 바와 같이 CA 연상이 성능위험과 재무위험에 유의한 영향력을 갖는 것으로 나타난 반면, CSR 연상은 성능위험과 재무위험에 대해 유의한 영향력을 갖지 않는 것으로 나타났다. 조절변수로 인한 상호작용효과와 관련해서는, CA 연상이 성능위험과 재무위험에 미치는 주효과에 대해 제품범주 지식과 관여는 각각 유의한 조절효과를 나타내었다. 하지만, CSR 연상이 성능위험과 재무위험에 미치는 주효과에 대해서는 제품범주 지식과 관여의 조절효과는 나타나지 않았다. 이러한 연구 결과를 통하여 제품의 기능적인 속성에 대한 정보가 부족한 제품에 대해 소비자가 지각하는 위험을 감소시키기 위하여, 기업은 CSR 연상보다는 CA 연상에 대해 강조할 필요가 있다는 결론을 내리게 되었다.
