This study is a descriptive study to provide basic data related to types of uniforms worn by nurses. Nurses, other medical center personnel, patients and their famillies were asked for their opinion on changing nurses’ uniforms and how the image of nurses is 1 elated to the type of uniform worn by the nurses. The data for this study were collected during the period from Feb. 25, 1993 to Mar. 26, 1993 at Y-University Medical Center from 132 nurses, 137 other medical center personnel, 117 patients and their families. The instruments used for this study were the Nurses’ Image Scale(NIS) developed by Bown(1986), and an instrument to measure opinions of uniform and cap using photographs of nurses’ uniforms that was developed by the researcher through a literture review. Data were analyzed using the SPPS / PC package, Statistics used for analysis were frequencies, percentages, paired t -test, and oneway ANOVA The results of this study are summarized as follows ; 1. Of the nurses, 84.3%, along with, 51.5% of the medical center personnel, 39.1% of the patients and their families agreed to a change in the color of nurses uniforms. 2. Similarly, 87.4% of the nurses,27.7% of the medical center personnel, 19.3% of the patients and their families were in favor of nurses not wearing caps. 3. Only 11.8% of nurses answered that a white uniform was important to the professional image of nursing. Only 2.4% of the nurses answered that a cap was very important to the professional image of nursing. 4. Only 1.6% of the nurses answered that a white uniform and cap were important to show the role of nurses in the twenty first century. 5. About 1/3, 36.5%, of the medical center personnel, the patient and their families answered that changing the color of the nurses' uniform will make a change in the image of nurses. 6. A White uniform and cap were seen as being im-portant in distinguishing nurses from other medical personnel in the hospital by 76.5% of the medical personnel, the patients and their families. 7. Nurses gave high marks to the idea of no cap regardless of the color of the uniform which would still portray the symbol of the nurses’ role, identity and would differentiate the role from other jobs. The patients and their families gave high marks to a white uniform with cap. 8. Generally, nurses, medical center personnel and patients and their families thought that a colored uniform with cap presented a good image of nurses. 9. There was a significant difference in the response among the three groups(F=24.65, P〈.001) to the figure in a white uniform with a cap, and the patients and their families thought it was the best portrayal of the image of nurses. There was a significant difference among the three groups(F=9.03, P〈.001) to the figure in a white uniform with no cap and the nurses indicated that it was the beat portrayed of the image of nurses. There was no significant difference among the three groups to the figure in a colored uniform with cap. There was a significant difference(F=17.50, P〈. 001) to the figure in a colored uniform with no cap, and the nurses indicated that it was the best portrayal of the image of nurses. In summary, the nurses wanted to change the color of uniform and not to wear a cap. But many of the medical center personnel, patients and their families indicated they did not agree with this idea. Therefore, changing the type of uniform worn by nurses should be done only after consideration has been given to the relation of the change to the professional role of nurses and the image of nurses held people in general. Suggestions arising from this study are as follows : 1. The relation between the role of nurses and their uniform was surveyed, and these results can be used as data when considering a change in uniforms. 2. A change in uniforms should be tried based on the norm established about uniforms. 3. The nurses did not want to wear a cap, but before a decision is definitely made it is necessary to study the philosophy related to the symbol of the cap because the figure of a nurse with a cap portrayed a positive image of the nurses. If the cap is kept, the symbol of the cap should be redefined. 4. In this study, only the image related to the uniform was examined, but in future studies it will be necessary to examine the practicality of various types of uniforms.

Care is a central concept of nursing. Nursing would not exist without caring. Care and quality of life are closely related. Human behavior is a manifestation of culture. We can say that caring and nursing care are expression of culture. The nurse must understand the relationship of culture with care for ensure quality nursing care. But knowledge of cultural factors in nursing is not well developed. Time and in - depth study are needed to find meaningful relationships between culture and care. Nurses recognized the importance of culturally appropriate nursing There are two care systems in culturally based nursing. The folk care system and the professional nursing care system. The folk care system existed long before the professional nursing care system was introduced into this culture. If the discrepancy between these two care systems is great, the client may receive inappropriate nursing care. Culture and subcaltures are diverse and dynamic in nature. Nurses need to know the caring behaviors, patterns, and their meaning in their own culture. In Korea we have taken some first step to study cultural nursing phenomena. It is not our intent necessarily to return to the past and develop a nationalistic of nursing, but to identify the core of traditional caring and relate that to professional nursing care. Our Assumptions are as follows : 1) Care is essential for human growth, well being and survial. 2) 7here are diverse and universal forma, expressions, patterns, and processes of human care that exist transcul - turally. 3) The behaviors and functions of caring differ according to the social structure of each culture. 4) Cultures have folk and professional care values, beliefs, and practices. To promote the quality of nursing care we must understand the folk care value, beliefs, and practices. We undertook this study to understand caring in our traditional culture. The Goals of this study were as follows : 1) To identify patterns in caring behavior, 2) To identify the structural components of caring, and 3) To understand the meaning and some principles of caring. We faised several questions in this study. Who is the care-giver? Who is the care-receipient? Was the woman the major care -giver at any time? What are the patterns in caring behavior? What art the priciples underlying the caring process? We used an interdisciplinary team approach, composed of representatives from nursing and anthropology, to contribute in -depth understanding of caring through a socicaltural perspeetive. A Field study was conducted in Ro-Bong, a small agricultural kinship village. The subjects were nine women and one man aged be or more years of age. Data were collected from january 15 to 21, 1990 through opem-ended in-depth interviews and observations. The interview focused on caring behaviors sorrounding birth, aging, death and child rearing. We analysed these data for meaning, pattern and priciples of caring. In this report we describe caring behaviors surrounding childbirth. The care-givers were primarily mothers- in -low, other women in the family older than the mother - to- be, older neighbor woman, husbands, and mothers of the mother-to- be. The care receivers were the mother-to-be the baby, and the immediate family as a component of kinship. Emerging caring behavior included praying, helping proscribing, giving moral advice(Deug - Dam), showing concern, instructing, protecting, making preparations, showing consideration, touching, trusting, encouraging, giving emotional comfort, being with, worrying about, being patient, preventing problems, showing by an example, looking after bringing up, taking care of postnatal health, streng thening the health condition, entering into another's feelings(empathizing), and sharing food, joy and sorrow The emerging caring component were affection, touching, nurtuing, teaching, praying, comforting, encouraging, sharing. empathizing, self - discipline, protecting, preparing, helping and compassion. Emerging principles of. caring were solidarity, heir- archzeal relationships, sex - role distinction. Caring during birth expresses the valve of life and reflects the valued traditional beliefs that human birth is given by god and a unique unifying family event reaching back to include the ancestors and foreward to later generations. In addition, We found positive and rational foundations for traditionl caring behaviors surrounding birth, these should not be stigmatized as inational or superstitious. The nurse appropriately adopts the rational and positive nature of traditional caring behaviors to promote the quality of nursing care.

It is widely recognized that primary health care in the community is one of the most important and effective health measures in these days. However, it is reality that unsatisfactory health care system, ineffective utilization of health care by the community people in the rural area are hampering better understanding for primary health care. Therefore promoting health for the rural people and increasing understanding about primary health care, the baseline survey in the community focused in examination for safe community water supply was carried out. The survey was conducted through August 25-31, 1986 in order to find out health problems and relevant factors and to define the demographic characteristics of $^*$Sanpuk village, Kumsa-Myun, Yuju-Gun, Kyunggi-Do, Korea. Household survey was carried out for every home by trained interviewers. The major results are found out as follows : 1) 84.2%(400 houses) of total households were surveyed because 15.8%(75 houses) were unable to survey due to either refusal against interview or absence of family. These 400 households were composed of 1,697 residents(male:830, female 867). Educational level of respondents showed 34.1% as elementary school graduated. Religion distribution showed Buddism(23.8%) as the most dominant. 50.7% of respondents married in the area. 2) Most households(91.5%) have lived in their own house in Sanpuk area. Average family size showed 4.3. More than half of residents(64.2%) have used public supplied water tap. Only 1.5% of the households had a flush toliet. The rest of households have still used primitive insanitary latrines. 3) 32.5% of residents have used gas burner for cooking and for heating in the house, and the coal briquet were used for boiler. Lack of convenient public transportation was the chief complaint for their day life. 4) Each household occupied 1,990 pyungs of rice paddy and 1,170 pyungs of ordinary field in average. Beside farming products, mushroom was the highest product. 5) Sixth percent of households in the survey area regularly participated in community meeting one hand and on the other hand 39.5% never participated. Most of respondents closely contacted with their neighbours and they seemed very friendly each other. 6) The prevalence rate of illness and injury during recent 15 days showed 48.3 per 1,000. The prevalence rate of chronic illnesses during the past one year showed 74 per 1,000. Injury and accident lead the higher portion(22.0%) in the former and in the latter pain(arthritis, back-pain) showed 27.0% as the dominant sickness. 87.8% of the ill residents in the former received medical treatment. As the most frequently utilized medical facility, the clinic or hospital were counted. Among the residents suffering from chronic illnesses, 77.3% in Sanpuk area get some kind of medical treatments and they rarely utilized the clinic or hospital. The reason why the patient did not receive any medical care was found out the fact that symptoms of illness was light or mild and economic problems was serious. 7) Average age of marriage showed 21.6 years old in the women and the average duration of marital period was shown for 15.1 years. The married woman in reproductive age in Sanpuk area had experienced pregnancies 4 times in the aver-age including 0.7 time of pregnancy in average were interrupted by induced abortion and 0.3 time by spontaneous abortion respectively. The practicing rate of the family planning of the married woman during reproductive ages showed 70.7% and the tuballigation was found out as the most frequently used contraceptives. 8) Among woman who has children under 2 years old, 70.0% had received the prenatal care for the last pregnancy. However, the average number of prenatal care visitis per woman showed 3.3 times. Fifty-two % of woman who received the postnatal care for the last delivery showed only 37.5%. 9) Immunization rate of the children under 2 years old showed relatively high and looked successful. The breast feeding for these children showed dominantly in the most. Most of the mothers in Sanpuk area had started the supplementary diet during weaning period of their infants of 6th and 7th month after birth. * : Sanpuk area is a demstration area for community development which has been supported by the Community Development Foundation during the part 10 years. The village is relatively closer to urban area such as Seoul, However, it has a similar characteristics shown as a remote village because of geographical location and inconvenient transportation at present.

이 연구는 1997년 3월부터 1999년 2월까지 경상북도 소재 일개 군지역에서 피부질환으로 피부과 전문의의 검진을 받은 환자 847명 중 설문조사가 가능하였던 760명의 환자를 대상으로 이들 환자별 성별연령별 분포를 조사하고 치료 경험 여부와, 처음 치료를 시작한 곳과 민간 요법이나 개인적인 치료법 사용여부 및 치료 경험이 있을 경우 그 효과에 대한 만족도를 조사하여 환자들이 피부 질환의 진료 및 치료에 있어 어떤 경로를 밟고 그 일반적인 치료 행태의 경향은 어떠한지를 분석하고자 시행하였으며 다음과 같은 결과를 얻었다. 1. 총 760명의 조사대상자는 남자가 283명으로 37.2%였고 여자가 477명으로 67.3%였다. 총 대상환자 중 20대 환자가 3.3%로 가장 적었고 60대 환자가 21.3%로 가장 많았다. 2. 대상 환자들에게 빈도가 높은 15개 질환은 족부 백선이 34.9%로 가장 많았고 노인성 소양증, 접촉성 피부염, 주부습진, 지루성 피부염, 화폐상 습진, 아토피성 피부염, 체부 백선, 조갑 백선, 심상성 여드름, 전염성 농가진, 박탈성 각질용해층, 만성 두드러기 및 전염성 연속중의 순이었다. 3. 환자들이 피부질환을 위해 최초로 치료받은 곳은 약국이 39.6%로 가장 많았으며, 피부과 전문의가 아닌 개인의원, 피부과 의원 및 종합병원 피부과의 순이었다. 4. 대상환자 760명 중 121명(15.9%)이 민간 요법을 사용한 경험이 있었으며 이 중 가장 많이 사용하는 방법으로서는 환부를 식초에 담그거나 도포하는 방법이었다. 이러한 민간 요법을 시행한 후 환자 본인이 느끼는 자각증상은 변화가 없었다는 경우가 가장 많았고 호전되었다, 악화되었다의 순으로 빈도가 높았다. 결론적으로 농촌지역의 경우 다수의 피부과 환자들이 약국에서 일차진료를 받고 있는 현실이며 피부질환에 대한 인식이 낮음으로 인해 의학적 근거가 없는 다양한 민간요업을 시행하고 있었다. 그러므로 환자들이 잘못된 치료 행태로 인해 경제적, 시간적 손실을 입지 않게 올바른 보건교육이 이루어져야 될것으로 생각된다.

2008년 9월 경상북도 영천시 소재 Y 지적장애인 특수학교에서 설사 유행이 신고되었고, 일부 환자의 검체에서 Shigella sonnei가 검출되었다. 이에 Y 학교와 초발 환자 신00이 기거하고 있던 경산시 소재 D 재활원에서 발생한 세균성이질에 관한 역학조사를 실시하였다. Y 학교와 D 재활원은 지적장애인을 위한 학교 및 생활시설로서 모두 직영급식을 하고 있다. 지적장애가 있는 학생과 원생들을 상대로 설문조사는 시행하지 않았고 교사와 직원들을 상대로 면담을 실시하였다. Y 학교와 D 재활원에서 직장 도말 검사를 각각 298건, 361건 실시하고 환경 검체 검사를 각각 60건, 20건을 실시하였다. 학교와 재활원의 환경조사를 실시하였고 음용수와 조리용수, 생활용수의 공급원을 파악하였다. 환자는 격리 치료하고 추가 환자 발생을 일일 능동 모니터링하였다. 환례는 2008년 9월 18일부터 9월 26일까지 Y 학교와 D 재활원의 구성원 중에서 설사(하루 2회 이상의 묽은 변)가 있는 경우 혹은 직장도말 배양검사 결과 Shigella sonnei 양성인 경우로 정의하였다. 환례 정의에 따라 조사 대상 659명 중 환례는 8명으로 1.2%의 발생률을 보였고 이들은 모두 Y 학교 학생이었다. 직장도말 배양검사 결과 Shigella sonnei가 5명의 학생에서 검출되었고, 이들 중 3명에서는 설사 증상이 있었으며 나머지 2명은 무증상이었다. 환례 8명 모두 단체숙식을 하고 있었는데 이들 중 2명은 Y 학교 기숙사 기린방에서 생활하였고, 4명은 D 재활원 온유방, 나머지 2명은 D 재활원의 까치방과 자비방에서 각각 생활하였다. Y 학교와 D 재활원의 환경조사 결과 특이사항이 없었으며, 공통적으로 음용수와 조리 용수는 상수도에서 공급받고 화장실의 생활용수는 하수도에서 공급받고 있었다. D 재활원의 지하수 1건에서 대장균군이 양성이면서 일반세균이 20,000 CFU/mL으로 나왔다. Pulsed-Field Gel Electrophoresis 검사에서 5건 모두 동일한 DNA 절편 양식을 보였다. D 재활원과 Y 학교에서 발생한 세균성이질은 동일한 균주에 의한 유행으로 판단한다. D 재활원의 온유방에서 현성 또는 불현성 감염자인 교사나 자원봉사자와의 직 간접 접촉을 통해 최초로 1명 이상의 원생에게 전파시켰을 가능성이 있다. 그 후 환례들과 직 간접 접촉에 의하여 D 재활원의 온유방 내, 다른 방과 Y 학교 학생에게 전파되었을 가능성이 있다고 추정한다. 단체 시설의 교사와 자원봉사자에 대하여 손씻기의 중요성이 더 강조되어야 하고 전염이 가능한 증상이나 질병이 있을 때에는 접촉이나 봉사 활동을 자제해야 할 것이다.

This descriptive study was conducted to understand the contents and degree of parental stress level in the NICU patients, and to give a baseline data in developing nursing intervention program. Subjects were the 62 mother of hospitalized newborn in NICU of 1 University Hospital in Taejon City from May 1st, 1999 to November 30th, 1999, who agreed to take part in this study. The instrument used in this study were Parental Stressor Scales : NICU(PSS:NICU) developed by Miles et al. and validated by 3 NICU practitioners and 3 child health nursing faculties. The questionnaire has 4 dimensions and 45 items; sight and sounds of NICU(5 items), babies' appearance and behavior(19 items), parental role alteration and relationship with their baby(10 items), communication with health team(11 items). The questionnaire asks parents to rate each item on a five-point Likert type scale that ranges from (1) to (5). Total scores representing overall stress from the NICU environment are calculated by summing response to each item. A high score indicates high stress. A subscale score is calculated by summing the responses to each item in the subscale. Cronbach's α coefficients were .93. The data was analyzed as average, Frequency, Standard deviation, t-test, ANOVA, Pearson correlation coefficient by use of SPSS/PC+. The results of this study is summarized as follows ; 1. The total perceived stress level score of mothers was slightly high(3.6±.7). The highest scored dimension was 'appearance and behavior of the baby'(3.9±1.5), and next were 'relationship with their baby and parental role change'(3.5±1.4), 'communication with health team'(3.4±.9), 'sight and sounds of NICU'(3.2±.8). 2. Two variables were statistically significant with PSS:NICU total scale ; mother's perceived severity of the baby's condition (r=.482, P=.002) and mother's religious attendance(t=2.83, P=.01). The more the mother perceive their baby's condition severe, the higher the total stress score. There were high stress score noted in the mother of no religious attendance. 3. Four variables were statistically significant with NICU environment subscale ; mother's educational background(F=3.45, P=.04), religious attendance(t=2.28, P=.04), sex of the baby(t=2.83, P=.01) and NICU patients' hospital day(r=.359, P=.004). That is mother with high educational background and girl baby were high NICU environment subscale score. 4. Four variables were statistically significant with appearance and behavior of the baby subscale ; when first saw baby(F=3.52, P=.04), incubator care(t=2.83, P=.01), mother's perceived severity of the baby's condition(r=.303, P=.017), number of NICU visit(r=.441, P=.002). That is, seeing the baby first in the NICU and recieved incubator care was very stressful. Also, the more the mother perceive their baby's condition severe and more NICU visit, the higher the appearance and behavior of the baby subscale stress score. 5. Four variables were statistically significant with relationship with their baby and parental role change subscale ; when first saw baby(F=3.37, P=.04), sex of the baby(t=2.36, P=.03), incubator care(t=5.60, P=.00), mother's perceived severity of the baby's condition(r=.401, P=.001). That is, seeing the baby first in the NICU and girl baby was very stressful. Also, the more the mother perceive their baby's condition severe, the higher the relationship with their baby and parental role change subscale stress score. 6. Three variables were statistically significant with communication with health team subscale ; mother's educational background (F=3.63, P=.04), incubator care(t=4.24, P=.00), gestational age(r=-.394, P=.047), and birth weight(r=-.460, P=.004). That is, mother with high educational background and receiving incubator care were high communication with health team subscale score. Also, the shorter the gestational age and smaller the baby's birth weight, the higher the communication with health team subscale score. In conclusion, information about physical environment of NICU, the mother's perceived severity of baby's illness state, maternal role change related variables and the knowledge of characteristics of NICU patients must be included in nursing intervention program of mother's of NICU patients in reducing the maternal stress and anxiety level.

본 연구의 목적은 4 종류의 저 침습 고정성 국소의치의 수직하중에 대한 저항을 연구하여 임상 활용에 도움을 주기 위함이다. 상악 우측 제 1 대구치 결손을 가정하여 상악 제 2 대구치와 제 2 소구치를 지대치로 하는 고정성 국소의치 금속 다이를 제작하고 4 종류의 저 침습 고정성 국소의치 (Resin bonded FPD, Two Key Bridge, Human Bridge without occlusal rest, Human Bridge with occlusal rest)를 제작하였다. 만능 시험기를 이용하여 수직하중을 가하여 실패 시의 최대 하중을 기록하고 실패 유형을 기록하였다. 평균 최대 하중은 Resin bonded FPD 군이 7,295 N, Two Key Bridge 군이 4,729 N, Human Bridge without occlusal rest 군이 2,190 N, Human Bridge with occlusal rest 군이 3,073 N 이었다. Resin bonded FPD, Two Key Bridge, Human Bridge 군 사이에는 통계학적 유의차가 있었으나 occlusal rest 의 유무에 따른 Human bridge 군 사이에서는 통계학적 유의차가 없었다. 보철물 실패양상은 Resin bonded FPD와 Two Key Bridge는 양측 지대치의 유지부 한쪽이 탈락되는 경우가 양측 모두 탈락되는 경우보다 많았으며 Human Bridge 군은 모두 지대치 양측의 유지부가 함께 탈락되는 경우가 한쪽이 탈락된 경우보다 더 많았다. 본 연구에서 저 침습 고정성 국소의치의 수직 하중에 대한 저항은 Human Bridge 군이 resin bonded FPD 군이나 Two key Bridge 군에 비하여 낮은 것으로 나타났다. 따라서 임상에 적용할 때에는 이와 같은 파절 저항을 고려하여 수복 위치의 최대 교합을 참고하는 것은 물론이고 각종 수복물의 탈락에 대한 저항, 그리고 치질의 삭제량, 환자의 협조도 등을 고려하여 각각의 환자에 적합한 수복물을 선택해야 할 것이다.

치과용 자석의 개선으로 자성 어태치먼트를 이용한 임플란트 피개의치의 사용이 늘고 있다. 또한 여러 형태의 자성 어태치먼트가 개발되어 임상 상황에 따라 적절히 선택하여 사용할 수 있게 되었다. 이에 시중에 판매되는 세 가지 형태의 임플란트용 자성 어태치먼트를 이용해 자성 어태치먼트의 형태와 임플란트 수에 따른 임플란트 피개의치의 유지력을 비교 분석하였다. 식립된 임플란트가 1개인 경우를 1군, 2개인 경우 2군, 4개인 경우를 3군으로 하였고, 자성 어태치먼트의 형태에 따라 flat type, cushion type, dome type으로 세분하였다. Instron으로 수직방향, 사선방향, 전후방향의 인장력을 가하여 자성 어태치먼트의 형태에 따른 유지력의 차이, 힘의 방향에 따른 유지력의 차이, 자성 어태치먼트의 수에 따른 유지력의 변화를 비교 분석하여 다음의 결과를 얻었다. 1) 임플란트의 수와 상관없이 수직력은 flat type이 가장 컸으며, 측방력은 dome type이 가장 작은 것으로 나타났다. 2) 임플란트가 1개일 때 flat type의 수직력이 전후방회전력보다 크게 나타났고, 임플란트가 2개일 때는 dome type과 flat type이, 임플란트가 4개일 때는 cushion type과 flat type에서 수직력이 전후방회전력보다 크게 나타났다. 3) 임플란트 수에 따른 유지력 측정결과, 자석의 형태에 상관없이 임플란트 수가 많을수록 유지력은 증가하였다. 이상의 결과로 볼 때, 큰 유지력이 필요한 환자에게는 flat type이, 유해한 수평력이 존재하는 환자에게는 dome type의 이용이 유리하고, 임플란트가 1개일 때 flat type, 2개일 때 dome type과 flat type, 임플란트가 4개일 때 cushion type과 flat type이 피개의치의 안정성이 더 좋은 것으로 나타났다. 또한 자성 어태치먼트의 형태에 상관없이 임플란트의 수가 증가할수록 더 큰 유지력을 나타냈다. 따라서 임플란트 피개의치 사용 시 적절한 유지력과 안정성을 얻기 위해서 임플란트의 수와 자성 어태치먼트 형태의 고려가 필요하다고 사료된다.
