  • 목조건축문화재는 그 나라의 정체성을 보여주는 가시적인 유물 가운데 하나이다. 문화재의 원형에 대한 개념이 정확하게 이해되지 않은 상태에서도 문화재는 '원형보존' 또는 '원형유지'를 보존관리의 원칙으로 삼았다. 더구나 요즈음은 국제적인 보존원칙의 흐름을 따라 문화재를 '역사적 대상물로의 가치'로서 중요하게 생각하고 있다. 이 논문은 목조건축문화재의 원형유지를 위해 어떤 부분을 모니터링 해야 하는가의 범위와 내용을 정해 보기 위한 시도의 결과이다. 목조건축문화재의 모니터링에 있어서 첫 번째로 해야 할 부분은 지면과 기단의 상태를 점검하는 일이다. 지면과 기단은 목조건축문화재가 오랫동안 서 있을 수 있도록 모든 힘을 받아 주는 곳이기 때문이다. 따라서 기단부와 낙수의 관계, 기단부의 침하 유무, 배수로의 유무와 구배 상태 확인 등을 모니터링 하였다. 두 번째는 기둥 부분이다. 기둥 기울음의 유무, 귀솟음과 안쏠림의 기법의 유무, 기둥 치수의 변화 유무, 기둥과 초석의 변위 발생 등을 확인하는 일이다. 기둥의 불안정성은 각 부재와의 이음과 맞춤 부분의 파손을 발생시키고 이로써 벽체의 손상까지로 이어지는 물리적 변화를 초래하기 때문이다. 세 번째는 지붕의 번와 유무, 번와에 따른 신·구 기와의 점유상태, 그에 따른 편심하중의 유무, 강우·강설에 의한 기와 사이의 이격 발생, 누수의 유무를 점검하였다. 지붕은 기와의 이격이나 파손에 의해 건물 내부로 누수가 지속되면 창방 이상을 부분 해체보수 해야 하기 때문에 가급적 원형유지를 위해서 모니터링 해야 한다. 시기적으로, 상태적으로 기준이 모호한 '원형보존'이나 '원형유지'를 문화재보존의 기본으로 하였어도 당시의 모든 현상은 문화재의 '원형'으로 보아야 한다. 그렇기 때문에 문화재돌봄에 있어서 기단부, 기둥, 지붕의 모니터링 범위는 당해 문화재에 어떠한 훼손이 일어나고 있는가를 확인하는 기준점이 된다. 다시 말하면 모니터링을 시작한 그 시점의 자료는 당해 연도의 '원형'이 된다. 지금에라도 현상에 대한 기록을 남기고 그것이 어떻게 변화되고 있는지, 훼손되고 있는지의 사진, 측정값, 도면 등의 여러 자료를 남겨두어야 후대가 필요로 하는 문화재의 '원형'에 대한 정보로 활용할 수 있을 것이다. 또 문화재 원형보존을 위한 모니터링의 분석에 따른 대안을 적극 도입하여야 한다. 그리고 문화재 모니터링의 결과물인 문화재의 현재 상태 및 상황을 여러 관련 기관과 공유하여서, 문화재의 '개입'에 의한 보존보다 예방보존을 구축해 나아가야 한다.

  • 공주 청량사지 오층 및 칠층석탑은 계룡산 삼불봉 아래에 있으며, 고려 중기에 창건한 것으로 알려진 탑으로 한 시대에 두 유형의 백제계 석탑이 공존하는 쌍탑으로서 역사적 및 학술적 가치를 인정받고 있다. 두 탑은 1944년 도굴로 칠층석탑이 전도되고 그 영향으로 오층석탑에 기울어짐이 발생하였다. 1961년에 석탑을 복원하였으나 구조적 불안정성은 지속적으로 제기되었다. 따라서 이 연구에서는 2021년 5월부터 2022년 3월까지 계측자료를 축적하고 계절적 특성을 검토하여, 동일 기간의 기온변화와 강수량에 따른 석탑의 미세거동을 해석하였다. 이 결과, 모든 계측기에서 일간 기온변화에 따라 미세한 열탄성거동을 반복하였으며, 경사와 변위 모두 미세거동이 나타났다. 경사계에서는 기온변화에 따라 석재의 표면과 내부에 포함된 수분이 팽축을 반복하며 미세한 움직임을 보였고, 변위계에서도 시계열에 따라 기온이 상승하면서 모두 이격거리가 감소하였다. 특히 오층석탑 상부는 북서쪽으로 최대 3.89° 거동하였으며, 칠층석탑은 북동쪽으로 최대 0.078° 기울었다. 최대 변위는 오층석탑과 칠층석탑에서 각각 0.127 및 0.149mm로 기록되었다. 이 값들은 계측 종료시점에 원래 상태로 회귀하는 경향은 있으나 완전히 회복하지 못하여 면밀한 감시가 필요한 상태를 지시하였다. 이 연구를 통해 획득한 결과는 두 석탑의 안정적 보존을 위한 기초자료로 활용될 수 있다. 이를 기반으로 다양한 환경요소를 고려한 거동특성이 분석되어야 하며, 계측시스템의 유지관리를 통한 예방보존이 지속되어야 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.

  • The prenatal care is the preventive medical service to help the pregnant mother deliver the healthy baby. It's regular examines give some chances to check-up the healthy conditions. This thesis concentrates on the CRM system to support an effective prenatal care system and prove the effectiveness of it. As CRM is the adapted management related to the customer's own information, it is important to develop the CRM model classified by the patients characteristics. A general hospital in Busan operated the CRM system to carry out the effective prenatal care and there is an analysis to ensure the effectiveness of CRM system for the pregnant women in our maternity ward. The results can be summarized as follows: 1) According to the comparisons with the CRM system, we can conclude the system is desirable. (1) Maternal Age : In the age distribution, the prenatal visit frequency, triple marker freqency, oral GTT and targeted ultrasonography in the experimental group in 30 to 34 years old is higher on the whole. For over 35 years old group, the higher frequency comes out in the oral GTT and targeted ultrasonography and for 25 to 29 years old group the different figure shows just in the targeted ultrasonography. (2) Area of residence: There is a clear difference in all the items in Busan and near area but no sign of difference in prenatal visits and oral GTT in other residencial area. Especially in the targeted ultrasonography the higher figure shows in the experimental group located in the both areas. The targeted ultrasonography is known as the specific examination which should be examined by the specialists, on the contrary the other examinations can be operated in the small clinic. So the public information and seminars related with ultrasonography increases the check-up frequency. The clinic requests some ultrasonographical examinations to the specialists in general hospital. (3) Parity: The clear difference shows that the CRM system causes the prenatal visit frequency to become higher in experimental group. The figure is 9.7 times and 8.6 times each. This is opposite that the past study said multiparity reduced the average prenatal visits. But the result of CRM is considered as the method to help the multiparity understand the importance of the prenatal care. (4) Obstetrical history: In the experimental group of the spontaneous delivery group, the figure is higher in the prenatal visit frequency, triple marker, oral GTT and targeted ultrasonography but the Caesarean section delivery group has higher figure in targeted ultrasonography. (5) In the first check-up, the rate of targeted ultrasonography in under 16 week pregnancy, in the 16 week pregnancy to 32 week pregnancy and the over 32 week pregnancy in the experimental group is upper than the compared one. For the oral GTT, there is a difference in under 16 week pregnancy but no difference in prenatal visits and triple marker. 2) The analysis of characteristics of prenatal care through the decision tree resulted in the fact that the most important variable is the residential area. After the delivery frequency is following, the obstetrical history and maternal age are in order. It is the same result in the triple marker and oral GTT. Consequently it is the same order of important variables in CRM system. The effectiveness of CRM system is proved in this study. The CRM system is a marketing method to control and lead the customers through the segmentation of customer data. It increases the new customer aquisition, maintenance of loyal customers, augmentation of customers value, activation of potential customers and creation of life time customers. So eventually it can enlarge the customers value. The medical institution should make efforts to establish the data base enforced by the customer's information on the underlying ordinary data system to carry out the CRM system effectively. In addition, it should develop the a variety of marketing strategy in order to set up one to one marketing satisfying the needs of individual patients.

  • The purpose of the study was to evaluate the educational content which had been given by midwifery training program. It was hoped that this result would help. It was sponsored by com-munity health worker plan effective health education. College of Nursing Ewha Womans University and The Korean Nurses Academic Society during the November 19 thru 24, 1979. It was carried out on July through on September 1980, and involved 22 community health workers. The results were as follows: 1. Most of the community health workers came from Seoul & Pusan areas and have been working at the hospitals. There were 31.82% of Head Nurses, 27.2% of Staff Nurses, 22.73% Nurse Supervisons, 13.6% of Nurse Directors and 4.5% of educational coordinator for Nurses. These participant had nurse-midwifery lincences by 63.64%. None of there had just midwifery lincences. 2, Age structures of the study population shows 31.82% of whom are.26-30 years and 22.73% of whom are 36. 40 years of age. This shown that seniority proportion is higher than the younger. There are 31.82% of 1-5 years, 27.27% of 6-10 year and 11-15 years, respectively by work career. 3. There are 54.55% of the institutions have opened their own midwifery training course for their nursing staff members. Because of lack of the facilities, shortage of instructors, and problems of administrative process. 4. According to the institution which opened for midwifery training courses, the participant was responsible for “midwifery”“Infant care”“MCH”“practice of midwifery”“Nursing adjustment”and“F. P.”5. During the midwifery couse, there were 8 institution who used the textbook and 4 institution who did not. Least of there referned to content matinals which was given by the sponsored. 6. There are 7 insititues who kept their training courses with other professional helps such as physicians., professiors and nurses. Some problems are pointed out by respondents such as“conflict with residents”“poor suportive administration”and“lake of manpower”. 8. The participant showed that they learned new knowledge as trends during this programs for there quality work so it need (one or twice times) a year. But they suggested that it needed more emphasis on the“maternal health care”and“role of the nurse-midwifery”. 9. The analysis of the results are as follows within the 6 areas which are given by the sponsored: There are highest ranks between“basic theory & family planning”“role of midwifery & nursing practice”. In the prenatal care the highest rank ware related to“health risk”on“idenify of risk symtoms”. In the health care areas which related to delivery, the responsers were related to“general conditions”or“high risk criteria”. In the health care area which related to high risk maternity care. In the neonatal health care, the highest rank was related to”health assessment of normal infant”. In the infant health care the responses was related to“abnormal symptoms”and“risk symptoms”. Actually, the participants show that they are more interested in“role of midwifery”“health assessment”and “high risk maternity care”are which emphasised on health promotion, health maintenance & disease preventive. 1) The midwifery training program need higher education for midwifery on a regular basis. 2) Within the open institution of midwifery training program, the nurses must be supported by their own institution and administry of social welfare must give systematic support. Also non-open institution must be open very soon. 3) All health workers including the residents & other workers, must cooperate for their phased common good of impovement of the maternity health. 4) Administration agonies & education institutions must provide the curriculum facilitis and administration systems which are needed for training of nurse-midwifery.

  • 배터리는 휴대폰, 전기자동차, 무인잠수정 등과 같은 분야에서는 주 동력원으로 사용되고, 일반 자동차에서는 시동기 또는 램프구동용으로 사용되며, 일반 선박에서는 비상전원으로 사용되고 있다. 2차 전지로는 납축전지와 리튬이온 배터리를 많이 사용하고 있으며, 납축전지는 가격이 비교적 저렴하고 안전하다. 리튬이온전지는 에너지 밀도가 높고 출력이 우수하며 수명이 긴 장점이 있으나 공기 중의 수분과 반응하여 폭발의 위험성을 가지고 있다. 그러나 최근에는 방수, 방염, 방진 기술의 발달에 힘입어 리튬배터리의 사용이 증가하고 있고, 특히 하이브리드 선박 및 전기추진 선박 등의 주동력원으로 사용될 만큼 그 사용범위가 점점 넓어지고 있으므로 좀 더 엄격한 배터리의 관리가 필요하다. 하이브리드 선박에서는 500kWh 이상의 대용량 동력원을 만들기 위하여 셀(Cell) 단위로 이루어진 수십 개의 리튬배터리가 들어 있는 팩들로 접속이 된 전원을 사용한다. 따라서 배터리 점검에 필요한 검출 전압, 전류 및 온도 데이터들을 관리용 서버로 보내 주는 유선 점검 및 감시시스템을 구현하는 데에는 많은 전선과 통신 모듈이 필요하다. 본 논문에서는 직렬통신 모듈보다 가격이 저렴하고 전선을 사용하지 않는 저 전력 블루투스(Bluetooth low energy, BLE) 무선통신 모듈과 전력선 모뎀을 사용하여 하이브리드 선박용 리튬배터리 저가형 점검 및 감시시스템을 구현하고자 한다. 배터리의 점검요소에는 잔존용량(State of charge, SOC)과 잔존수명(State of health, SOH)이 있으며, 제안한 시스템은 이들을 규칙적으로 점검하여 배터리의 수명 예측과 예방 정비를 할 수 있기 때문에 안전사고를 방지할 수 있을 것으로 전망된다.

  • 국내 건축물 중 업무시설은 국가 경제발전 및 산업구도의 변화와 더불어 급속도로 보급되기 시작하여 2012년 수도권 기준 소방대상물 현황 31개종 중 공동주택 다음으로 많은 비중을 차지하고 있는 주요 시설물이다. 그러나 2014년 현재 수도권지역 업무시설 중 70% 이상이 사용기간 15년 이상으로 주요 건축 마감재의 노후화와 기능저하가 시작되는 등 수선이 시급한 업무시설이 지속적으로 증가하고 있는 실정이다. 특히, 업무시설은 사옥 또는 임대사무실의 목적으로 활용되고 있어 시설물의 노후화와 기능 저하가 초래될 경우 건축주와 유지관리 주체에게 임대 경쟁력 저하 및 부동산 가치 하락 등의 문제점을 가져올 수 있다. 이와 같은 시설물의 노후화와 기능 저하를 예방하기 위해서는 준공 후 경과연수에 따라 수선율을 기준으로 한 예방적 차원의 계획 수선을 필요로 한다(La et al. 2001). 이러한 수선율을 기준으로 하는 국내의 수선기준들은 그 대상의 범위가 주로 공동주택과 공공기관 시설물에 국한되어 있어 업무시설에 해당 기준을 적용하기에는 한계성이 있으며, 현업에서의 수선계획 수립을 위한 수선율 기준의 적용성 제고를 위해서는 필수적으로 연간단위의 마감재별 수선율 데이터가 요구되고 있는 것으로 조사 분석되었다. 따라서 본 연구의 목적은 6개소 업무시설의 실제 수선이력데이터를 수집 및 분석하여 업무시설을 대상으로 한 건축 마감재의 수선율 산정 모형을 개발하고 사례적용을 통해 도출된 마감재별 연간단위 수선율의 적정성을 검증하는 것이다. 본 연구의 결과물은 업무시설의 건축주 및 유지관리 주체들로 하여금 발생 가능한 돌발적 보수비용과 기회비용의 낭비를 예방케 함으로써 보다 효율적인 유지보수 예산의 계획과 집행을 가능하게 할 수 있을 것으로 기대된다.

  • 1. 1개월, 2개월, 3개월 투여 시 혈압은 세 군간에 유의한 차이가 나타났으며 한국 홍삼군 및 중국 홍삼군은 대조군에 비해 혈압 감소가 나타났다.(P<0.05) 각 군별로 보면 한국 홍삼군의 경우 0-1개월, 1-2개월 사이에 혈압이 유의하게 감소하였으며, 중국 홍삼 투여군의 경우 0-1개월에만 유의한 감소를 보였다.(P<0.05) 2. 1개월 투여 그룹의 경우, 혈관벽 두께는 세 군간에 유의한 차이를 보이는 것으로 나타났고, 각 군 간의 차이를 비교하였을 때 중국 홍삼군의 경우 다른 두 군에 비해 혈관벽두께 감소가 유의한 차이를 보였다.(P<0.05) 2개월 투여 그룹의 경우, 혈관벽 두께는 세 군간에 유의한 차이를 보이는 것으로 나타났고, 각 군 간의 차이를 비교하였을 때 중국 홍삼군의 경우 다른 두 군에 비해 혈관벽 두께 증가가 유의한 차이를 보였다.(P<0.05) 3개월 투여 그룹의 경우, 혈관벽 두께는 세 군간에 유의한 차이를 보이는 것으로 나타났고, 각군 간의 차이를 비교하였을 때 중국 홍삼군의 경우 한국 홍삼군에 비해 혈관벽 두께의 증가가 유의하였으며 대조군에 비해서는 혈관벽 두께 감소 경향을 나타내었으나 통계적 유의성은 없었다. 한국 홍삼군의 경우 두 군에 비해 혈관벽 두께의 감소가 유의하였다.(P<0.05) 3. 대동맥 조직 병리 검사 변화상 한국 홍삼군은 모두 대동맥 벽이 잘 유지되어 있고 단층 혈관 내피 세포가 잘 유지되어 있으나, 중국 홍삼의 경우 1개월, 2개월, 3개월 투여시 세포핵의 비후가 비교적 뚜렷하게 관찰되며 세포핵의 방향성(Orientation)과 극성(Polarity)의 소실이 특징적으로 관찰되었고 평활근 섬유가 갈라지거나 찢어진(Split or tearing) 양상을 관찰할 수 있었다. 이상으로, 홍삼 투여 시 혈압 강하 효과가 나타남을 알 수 있었고, 한국 홍삼이 중국 홍삼에 비해 혈압 하강 효과를 좀 더 지속시킬 가능성 및 대동맥 조직 병리 소견 상 혈관 보호 효과에 대한 추론을 할 수 있었다.

  • 본 연구는 대구 경북지역 뇌졸중 환자들의 생활습관 및 식행동 특성을 분석하여 뇌졸중과 관련 있는 위험요인을 파악함으로써 지역민의 뇌졸중 예방을 위한 영양교육의 기초자료를 얻고자 수행되었다. 조사 대상자는 뇌졸중으로 처음 진단받은 입원 환자 100명(남자 50명, 여자 50명)을 환자군으로 하고 같은 기간 동안 뇌졸중 병력이 없고 환자군과 연령이 비슷한 지역 사회 주민 150명(남자 75명, 여자 75명)을 대조군으로 하였다. 조사는 일반특성, 생활습관, 식행동 특성, 식품섭취빈도, 식품 기호도 등의 내용을 포함한 설문지를 이용하여 조사자와 직접 면접을 통하여 실시하였으며 연구의 결과를 요약하면 다음과 같다. 뇌졸중 환자의 평균 연령은 남자 63.5세, 여자 69.9세였으며 일반 특성사항에서 환자군이 대조군에 비해 유의적으로 높은 것은 BMI, 당뇨병 고혈압과 심장병의 유병율, 뇌졸중과 당뇨병 고혈압의 가족력과 시골 거주율이었고, 유의적으로 낮은 것은 교육수준이었다. 생활습관에서 전체적으로 환자군은 대조군에 비해 흡연율이 유의적으로 높았고 녹차섭취와 규칙적 운동습관이 유의적으로 낮았다. 성별로는 남자는 흡연율과 규칙적인 운동 여부에서, 여자는 녹차섭취와 규칙적인 운동 유무에서 환자 대조군 간 유의한 차이를 보였다. 식행동 특성에서는 환자군은 대조군에 비해 불규칙한 식사, 과식, 육식의 비율이 높았고, 충분히 씹는 습관과 한식 섭취 비율이 유의적으로 낮았다. 식품섭취빈도는 전체적으로 환자군은 식용유, 참기름의 섭취 빈도가 대조군에 비해 유의하게 높았으나 콩제품, 채소류, 버섯류, 해조류, 종실류, 생선 어패류, 올리브유, 두유, 녹차, 과일 주스의 섭취 빈도가 유의하게 낮았다. 식품 기호도에서는 환자군은 대조군에 비해 닭고기, 계란, 볶음, 짠맛, 단맛의 선호도가 유의적으로 높았고 국류, 찌개류, 김치류, 해조류, 생선류, 우유 및 유제품, 콩유, 채소류, 과일류, 무침조리법의 선호가 유의적으로 낮았다. 본 연구 결과, 높은 BMI, 당뇨병과 고혈압의 유병, 뇌졸중 가족력, 흡연, 과식과, 육식의 식습관은 뇌졸중의 위험인자로 나타났고, 규칙적 운동습관과 녹차 섭취, 음식을 충분히 씹는 습관, 한식의 섭취, 콩 제품과 채소류, 버섯류, 해조류 생선 어패류, 두유, 녹차의 잦은 섭취가 보호인자로 나타났다. 따라서 정상 체중을 유지하고 고혈압, 당뇨병과 같은 선행질환을 예방하고 관리하는 것이 뇌졸중을 예방하기 위한 중요한 생활습관이라 생각된다. 또한 녹차의 섭취와 금연, 규칙적인 운동은 남녀 모두에서 뇌졸중을 예방하는 좋은 생활습관이며 규칙적인 식사와 과식금지, 충분히 씹는 습관, 단 음식의 절제, 채식과 육식을 가리지 않고 골고루 섭취하는 것, 조리법으로는 무침, 초무침을 선택하는 것이 뇌졸중을 예방하는 좋은 식습관인 것으로 나타났다.

  • The home health care industry has grown rapidly and can be expected to continue to grow in the foreseeable future. Home health care refers to the practice of nursing applied to clients with a health condition in the clients place of residence. clients and their designated care givers are the focus at home health nursing practice. The goal of care is to initiate. manage and evaluate the resources needed to promote the clients optimal level of well-being and function. Nursing activities necessary to achieve this goal may warrant preventive maintenance and restorative emphases to prevent potential problems from developing. Many project program were suggested home health care model for Korea's health care system and policy direction for expansion and establishment of home health care .But the aim of this paper is to provide on overview for theoretical frame work in home health care. Theories and conceptual frameworks or models are important nursing because they define and guide the boundaries of professional practice and identify key nurse-patient-caregiver relationships that emerge with caring. Following is the research with an investigation of the literature review in the University of Arizona international medline database, In conclusion, are as followers: First, many nursing theorists have had a tremendous impact on nursing practice. the following highlights those nursing theorists that are particularly helpful in understanding home health care. 1. Florence Nightingale : Our earliest theoretical legacy. Nightingale's believes are reflected in basic infection control practice such as hand washing and infectious waste disposal and are key nursing interventions in home care. 2. Martha Roger's :Science of unitary human beings theory. Rorger's believed that the focus of shared. non invasive healing modelities is the human environmental field rather than direct physical care. These modelities continue to evolve as our awareness (reflecting greater diversity, faster rhythms, motions, and ways of knowing) transcends time and space, allowing individuals to get in touch with their integral nature of unbroken wholeness. On people as ever changing energy fields have special relevance in home care especially with hospice and palliative care applications. 3. Madeline Leininger's; Transcultural nursing theory. Home care nurses move through a variety of communities and often care for patients from different cultural back grounds. Therefore Leininger's work has a good that with home care because home care nursing practice is very culturally focused. 4. Dorothea Orem's : Self care deficit theory. Orem's theory views care as something to be performed by both nurses and patients. The role of the nurse is to provide education and support that help patients acquire the necessary activities to perform self-care. Orem's theory is foundational to have care because it begins to truly acknowledge the role of the patient in managing his or her own health. which is referred to as self-care. 5. Margaret Neuman's; Health as expending consciousness theory. Neuman believes that health compasses disease and reflects an underlying pattern of person-environment interaction. A key application of 'Neuman's work to home care is for nurses to understand that health and illness do not necessarily exist at opposite ends of a continuum. 6. Jean Watson's: Theory of human caring. Watson's theory of human caring in nursing proposes human caring as the moral ideal of nursing. Nurses participate human caring to protect, enhance and preserve humanity by assisting individuals to fing meaning in illness. pain and existence and to help others gain self knowledge. self control. and self healing such thinking lends richness to theory development. as well as clinical practice in home care. Second, Robin Rice : Dynamic self determination for self care. (A theoretical framework for home care) Dynamical self determination for self care can be useful to home care nurses in a variety of ways. As research tool it can be reflected in the interview process when the home visit. The home care nurse's role is that of facilitator of patient self-determination for self care through numerous strategies. including patient education and case management.
