This study was conducted to measure the degree of Korean Gender Egalitarianism among the students from six different high schools(132 girls, 127 boys) in Sunchon si, Chunnam province from Dec. 7th to Dec. 15th in 1999. The survey on gender egalitarianism was done in relation to the public understanding of the subject matter, parents' hug times, and parent's communication skills. Korean gender egalitari- anism scale was standardized by Korea Woman Developmental Institutes in 1999. The data was analyzed by SAS program. Results were as follows: 1) Generally, girls are more conscious of gender egalitariannism than boys(t=-13.79, p<.001). Above all, the younger the students are, the more they feel equal(F=8.01, p<.01). In sibling cases, two sisters have the highest level of gender egalitarianism while two brothers have the lowest level of gender egalitarianism(F=9.20, p<.001). Students who come from religious families are more inclined to demonstrate gender equality(t= 2.42, p<.05). However, there is no difference in relation to the parents' ages or academic background or harmony within the family. 2) There is no difference that girls and boys generally communicate with their parents. In ages, 17 years old students communicate more than 18, 19 with parents(father F=3.97 p<.05ㆍmother F=5.31, p<.01). That is, the younger students can communicate with their mothers more often than the older ones. In sibling cases, two sisters have more openly communication to parents while two brothers have(F=2.84, p<.05). Students communicate with their parents regardless of parents' academic background. But those from the family in harmony have more open chance to communicate than those who are not in hamony(father F=21.66, p<.001ㆍmother F=13.37, p<.001). They can comm -unicate with their parents better when their fathers hug them than when they didn't get hugs(father t=-4.76, p<.001ㆍ mother t= -2.34, p<.05). They can also communicate with their patents better when their mothers hug them once or more than when they didn't get hugs(father t=-3.78, p<.001ㆍmother t=-5.64, p<.001). 3) There is no difference whether the father hugs or not, but the mother's hug is very important because students whose mothers hug them once or more have significantly more gender egalitarianism than those students whose mothers didn't do(t=-3.98, p<.001). Based upon these results, it is recommended that we reconsider the role of gender in the socialization of high school students and also include gender egalitarianism in sex education. In this context, further study should be done for the improvement of students' communication within the framework of egalitarianism based upon parents' hugs(semi-language). Continued study is especially important in regards to the mother's hug and its enhancement of the students' gender egalitarianism.

현재 개발된 GPU 가상화 기술은 모두 미세한 시분할 기법에 의한 스케줄링을 사용하기 때문에 어플리케이션 실행을 위한 오버헤드를 필요 이상으로 유발한다. 또한 이들은 가상 머신 모니터에 GPU 컴퓨팅 API를 포함하고 있어서, 가상 머신 모니터의 이식성이 약하다. 본 논문에서는 이질적 컴퓨팅 시스템에서 바이오 어플리케이션에 최적화된 GPU 가상화 기술을 제안하며, 공개 소스 Xen을 사용하여 개발하였다. 우리가 제안하는 방법은 가상 머신 간의 GPU 공유를 시분할에 의존하지 않는다. 대신에 하나의 가상 머신이 GPU를 할당 받으면 그 가상 머신이 어플리케이션을 종료할 때까지 GPU를 사용하도록 허용한다. 이렇게 하여 바이오 어플리케이션의 성능을 향상시키고 GPU의 활용률을 높인다. GPU 가상화의 이식성을 높이기 위해 하드웨어가 지원하는 IOMMU 가상화를 이용하여 GPU에 대한 직접 접근 통로를 제공한다. 미생물 유전체 분석 어플리케이션을 대상으로 성능을 분석한 결과, 본 연구에서 제안하는 직접 통로 방식에 의한 GPU 가상화는 Domain0를 통한 접근에 비해 오버헤드가 적었다. 또한 직접 접근 방식에 의한 가상 머신의 GPU 접근은, 비가상화된 머신과 거의 성능의 차이가 없었다.

암석 분류에 필요한 인적, 시간적 소모를 최소화하기 위해 최근 인공지능을 활용한 암석 분류 연구가 대두되었다. 이에 본 연구에서는 편광현미경 박편 이미지를 활용하여 염기성 화산암을 세분류하고자 하였다. 분류에 사용된 인공지능 모델은 Tensorflow, Keras 라이브러리를 기반으로 합성곱 신경망 모델을 자체 제작하였다. Olivine basalt, basaltic andesite, olivine tholeiite, trachytic olivine basalt 기준시료 박편을 개방 니콜, 직교 니콜, 그리고 gypsum plate를 장착하고 촬영한 이미지 총 720장을 인공지능 모델에 training : test = 7 : 3 비율로 학습시켰다. 학습결과, 80~90%이상의 분류 정확도를 보였다. 각각의 인공지능 모델의 분류 정확도를 확인하였을 때, 본 모델의 암석분류 방식이 지질학자의 암석 분류 프로세스와 크게 다르지 않을 것으로 예상된다. 나아가 본 모델 뿐 아니라 보다 다양한 암석종을 세분시키는 모델을 제작하여 통합한다면, 데이터 분류의 신속성과 비전문가의 접근성 모두를 만족시키는 인공지능 모델을 개발할 수 있으며, 이를 통해 암석학 기초연구의 새로운 틀을 마련할 수 있을 것으로 생각된다.

본 연구는 첫 자녀 출산 후 부부관계 경험 및 적응 과정에 대한 이해를 위해 근거이론적 접근에 기초한 질적 분석을 시도하였다. 결혼 기간 5년 미만, 첫 자녀 출산 후 3년 이내의 부부 13쌍에 대해 심층 면담이 진행되었다. 면담 자료를 대상으로 범주화 작업을 거쳐, 출산 후 부부관계 경험 및 적응에 대한 패러다임을 추출할 수 있었다. 첫 자녀를 출산한 부부들에게 관계 변화를 야기하는 원인적 조건은 삼자적 가족구조로의 전환 및 결혼 적응 수준이었으며, 중심 현상으로는 양육 및 가사 부담, 출산 후 부부관계의 변화가 특징적으로 관찰되었다. 이러한 중심현상은 남편의 지원과 관심, 원가족 지원의 중재 변인을 통해 그 강도가 완화 또는 악화되었다. 작용/상호작용적 전략에서 추출된 주요 범주는 새로운 역할 인식과 적극적인 수용, 가족에 대한 의미부여였으며 이러한 전략이 성공적으로 진행되었을 때, 완성체로서의 가족 구성과 공유된 가치 경험이 얻어질 수 있었다. 선택 코딩을 통해 이론화를 시도한 결과 '부부의 새로운 역할 인식과 수용 및 우리성(We-ness)의 추구'라는 핵심범주가 추출되었다. 임신과 출산, 양육 전 과정에 걸쳐 부부가 하나의 단위로 움직이며, 적극적인 관심과 참여를 보이는 것으로 정의되는 '우리성'의 획득은 출산과 양육이라는 생애 전환기적 사건을 맞닥뜨린 부부가 이에 적응적으로 대응하고 안정된 부부관계를 유지하게 하는 근거가 되는 것으로 나타났다.

This studies designed to work out a theoretical framework on the experience of sexual abuse from the perspective of grounded theory in an effort to provide more practical and efficient nursing intervention for female victims. The subcategories identified were "sexual abuse", "threatening", "absent mindness", "embarrassment", "horripilation", "dizziness", "wondrousness", "filthiness", "sexual curiosity", "violence level", "victim's age", "neighbors response", "victims personality", "common experience", "sexual abuse information", "family relations", "level of familiarity", "hiding", "suppression", "self-torture", "self-protection", "avoidance", "asking aid", "withdrawal", "hatred", "confusion", "dodging, "remmant", and "pursuing". The 29 subcategories given above were further integrated into 16 categories such as "victimizedness", "being astounded", "filthiness", "degree", "developmental stage", "response pattern", "personality", "rarity", "information availability", "family support", "cover-up", "escaping", "informing", "negative internalization", and "positive pursuit of change". The core categories linked to all the other categories turned out to be "being taken aback" and "filthiness" incorporating the relevant subcategories. A total of 23 theoretical hypothesis emerged in the process of analyzing data. 1. the grater sexual curiosity, the weaker the senses of being taken aback and filthiness. 2. The weaker sexual curiosity, the stronger the senses of being taken aback and filthiness. 3. The stronger the level of violence, The more violent the senses of being taken aback and filthiness. 4. The lower the level of violence, the weaker the senses of being taken aback and filthiness. 5. The younger the victims, the stronger the senses of being taken aback and filthiness. 6. The older the victims, The weaker the senses of being taken aback and filthiness. 7. 'Escaping' will transpire regardless of the given circumstances. 8. The weaker the senses of being taken aback and filthiness, the more probable 'informing' and 'escaping' transpire. 9. The stronger the senses of being taken aback and filthiness, the more probable 'informing' and 'escaping' transpire. 10. The more protective the response from 'informing' and 'escaping' transpire around, the more likely the response to being taken aback' and 'filthiness' will be 'informing' and 'escaping'. 11. The more repelling the response from around, the more likely the response to 'being taken aback' and 'filthiness' will be 'covering-up' and 'escaping'. 12. The more open minded the personality of the subject, the more likely the response to 'being taken aback' and 'filthiness' will be 'informing' and 'escaping'. 13. The more closed the personality of tile subject, the more likely the response to 'being taken aback' and 'filthiness' will be 'covering-up' and 'escaping'. 14. The more frequent the experience of sexual abuse, the more likely the response to 'being taken aback' and 'filthiness' will be 'informing' and 'escaping'. 15. The less frequent the experience of sexual abuse, the more lilely the response to 'being taken aback' and 'filthiness' will be 'covering-up' and 'escaping'. 16. The more available information concerning sexual abuses, the more likely response to 'being taken aback' and 'filthiness' will be 'informing' and 'escaping. 17. The less available information concerning sexual abuses, the more likely the response to 'being taken aback' and 'filthiness' will be 'covering-up' and 'escaping'. 18. The more cohesive the family of the subject, the more likely the response to 'being taken aback' and 'filthiness' will be 'informing' and 'escaping'. 19. The less cohesive the family of the subject, the more likely the response to 'being taken aback' and 'filthiness' will be 'covering-up' and 'escaping'. 20. The less familiar the subject is with the abuser, the more likely the response to 'being taken aback' and 'filthiness' will be 'informing' and 'escaping'. 21. The less familiar the subject is with the abuser, the more likely the response to 'being taken aback' and 'filthiness' will be 'covering-up' and 'escaping. 22. The more likely the response to 'being taken aback' and 'filthiness' is 'informing and 'escaping', the more positive changes the subject will pursue. 23. The more likely the response to 'being taken aback' and 'filthiness' is 'covering-up' and 'escaping', the more negative changes the subject will pursue. The following four hypotheses were conformed in the process of data analysis. 1) In case the level of violence is strong but 'being taken aback' and 'filthiness' in weak because of strong sexual curiosity and also if information concerning sexual abuse is not readily available and the frequency is low, negative internationalization marked by 'covering-up' and 'escaping' will take place despite the fact the subject is open-minded, the family is cohesive and the abuser is unfamiliar. 2) In case the level of violence is weak but 'being taken aback' and 'filthiness' is weak combined with weak sexual curiosity and also if information concerning sexual abuse is readily available and the response from around is protective and the frequency is high, the subject will pursue positive changes to 'being taken aback' and 'filthiness', further aided by the fact that the subject is open-minded, the family is cohesive and the abuser is unfamiliar. 3) In case the level of violence is strong and 'being taken abuse' and 'filthiness' is strong because of weak sexual curiosity and also if information concerning sexual abuse is reading available and the response from around is readily available and the response from around is protective and the frequency is low, the subject will persue positive changes marked by 'informing' and 'escaping' despite the fact that the family cohesion is weak and the abuser is familiar. 4) In case the level of violence is strong and 'being taken aback' and 'filthiness' is strong because of weak sexual curiosity and also if information concerning sexual abuse is not readily available and the response from around is respelling and the frequency is low negative internalization like 'covering-up' and 'escaping' will take place, further aggravated by the fact that the subject's personality is closed, family cohesion is weak, and subject is familiar. On the basis of the above finding, it is recommended that nursing intervention should focus on promoting the milieu conductive to the victims pursuing positive changes along with the adequate aids from protection facilities as well as from the people around them.

Health education, as the most fundamental concept for national health promotion, alms for developing the self-care ability of the general public. High school days are regarded as the period when most important physical, mental and social developments occur, and most health-related behaviors are formed. School health education is one of the major learning resources influencing health potential in the home and community as well as for the individual student. High school health education in Korea has a fundamental systemic flaw in that health-related subjects are divided and taught under various subjects areas at school. In order to achieve the goal of school health education, it is essential to make a systematic assessment of the learner's concerns connected with his health and life, and the factors affecting them. So far, most of the research projects that had been carried out for improving high school health education were limited in their concerns to a particular aspect of health. Even though some had been done in view of comprehensive school health education, they failed to Include a health assessment of the learner. Therefore, in this study the high school students' concerns related to health and life were investigated in the first place on the basis of the PRECEDE model, developed by Green and others for the purpose of a comprehensive diagnostic research on high school health education. This study was done in two steps : one was the basic study for developing research instrument and the other was the main one. The former was conducted at five high schools in Seoul and Cheongju for 2 months-beginning in March, 1996. The students were asked to respond to questions related to their health and lives in unstructured open-ended question forms. On the basis of analysis of the basic study, the diagnostic instruments for the quality of life, health problems, health behavior and educational factors were constructed to be used for the collection of data for main study. An expert panel and the pilot study were used to improve content validity and reliability of the instruments. The reliability of the instruments was measured at between .7697 and .9611 by the Cronbach $\alpha$. The data for this study were collected from the sample consisted of the junior and senior classes of twenty general and vocational high schools in Seoul and Cheongju for two months period beginning in July, 1996. In analyzing the data, both t-test and $X^2$-test were done by using SAS-$PC^+$ Program to compare data between the sexes of the high school students and the types of high school. A canonical correlation analysis was carried out to determine the relationships among the diagnostic variables, and a multivariate multiple regression analysis was conducted by using LISREL 8.03 to ascertain the influences of variables on the high school students' health and quality of life. The results were as follows : 1) The findings of the hypothesis tests (1) The canonical correlation between the educational diagnosis variables and behavioral, epidemiological, social diagnosis variables was .7221, which was significant at the level of p<.001. (2) The canonical correlation between the educational diagnosis variables and the behavior variables was .6851, which also was significant (p<.001). (3) The canonical correlation between the behavioral diagnosis variables and the epidemiological variables was 4295, which was significant (p<.001). (4) The canonical correlation between the epidemiological diagnosis variables and the social variables was .6005, which was also significant (p<.001). Therefore, the relationship between each diagnosis variable suggested by the PRECEDE model had been experimentally proven to be valid, supporting the conceptual framework of the study as appropriate for assessing the multi-dimensional factors affecting high school students' health and quality of life. Health behavior self-efficacy, the level of parents' interest and knowledge of health, and the level of the perception of school health education, all of which are the educational diagnostic variables, are the most influential variables in students' health and quality of life. In particular, health behavior self-efficacy, a causative factor, was one of the main influential variables in their health and quality of life. Other diagnostic variables suggested in the steps of the PRECEDE model were found to have reciprocal relations rather than a unidirectional causative relationship. The significance of this research is that it has diagnosed the needs of high school health education by the learner-centered assessment of variety of factors related to the health and the life of the students. This research findings suggest an integrated system of school health education to be contrived to enhance the effectiveness of the education by strengthening the influential factors such as self-efficacy to improve the health and quality of the lives of high school students.

The purposes of study was: 1. To identify the direction and scope of research activities in Korean Nursing. 2. To discuss the unique problems present in Korea that warrant nursing research. 3. To delineate the factors that facilitate and/or hinder nursing research in Korea. This study was conducted at six colleges of nursing in Korea. The schools which were selected had doctoral programs at the time, the data were collected in 1990. Four of the schools were located in the metropolitan area of the capital city, Seoul, and two were in two other cities similar in size. The total population of the study was 283 nurses. The instrument for the research was the English version of Research Profile Questionnaire which was translated into Korean by the researchers and was validated in its translation by two professors. A pretest procedure was done before the data collection process. Of the population of 283, 210 subjects received the questionnaire and 150 subjects responded(71.4%). Excluding incomplete questionnaires, 141 questionnaires were utilized for data analysis. Data were analyzed using descriptive statistics. Responses to open-ended questions were content analyzed for themes and categories. Results of the study were as follows : Respondents currently , involved in nursing research numbered 108(76.6%), but 33(23.4%) did not have any research experience. The inexperienced respondenLs tended to be younger than the experienced subjects and most( 60.6%) were employed in hospitals, while 82.4 percent of the experienced nurses were employed in nursing schools. Among the respondents with research experience, 68.5 percent were involved in one to three projects and 31.5 percent were engaged in four or more projects. The experienced nurses indicated that nursing research in Korea is active. On the other hand, the responses of the inexperienced were that nursing research is not active. The most frequently selected research subjects were patients(76.9%, 83 respondents) followed by nurses, healthy persons and nursing students. The relatively high percentage of healthy persons as study subjects, could be explained as a concern of nurses for healthy persons as well as for ill patients. The aforememioned literature review showed a dramatic change in the kinds of study subjects; approximately 33 percent were patients but 25 percent were healthy subjects of various ages. The hospital was the prevailing research setting(67.6%) but at the same time various community settings were used. This is a changing phenomena in nursing research of Korea. Current research designed to build on previous studies amounted to 75 percent; about 39.8 percem were theory and hypothesis generated. Over 65 recommended additional research focusing on hypothesis-testing 0:' theory building. The previously quoted literature review found that only 4.0 percent of the study quescions were developed from a theoretical framework. The most frequently listed current major focus of nursmg research was stress and adaptation. Patients with cancer, pain, social support and care of the elderly were the next most frequently reported. These concerns may reflect problems associated with a technological and industrializing societyl. The most frequently identified problem was lack of clinical research. The need for replication research and research that contributes to the accumulation of nursing knowledge were found to be rare in Korean research. A need for theory testing and theory construction research was also identified. Although advanced statistical methods were often utilized in nursing research, the results were frequently considered by the interviewers not to be applicable in practice, and readers had difficulty in comprehending the findings. Even though the number of clinical nurses involved in research is increasing, it is still considered inadequate. Among 108 respondents, 83(76.9%) gave lack of time as a barrier to conducting nursing research. Over fifty percent of the respondents reported lack of funding or, personally, low confidence in research skills as barriers. The respondents offered 183 suggestions for future emphasis in nursing research. Among the 51 areas of emphasis, clinical research received the highest number and nursing intervention was next. The findings suggested that nursing research should be based on theory, be related to practice and relevant to the situation of a unique Korean culture.

본 연구는 노인장기요양보험제도의 방문간호 중에서 치과위생사의 업무인 방문구강위생이 포함되어있으므로 치과위생사의 인지도를 파악하고자 2009년 1월부터 4월까지지 서울특별시, 인천광역시, 경기도의 치과병 의원에서 근무하는 치과위생사 259명을 대상으로 설문조사를 실시하였으며, 주요한 연구 결과는 다음과 같다. 1. 노인장기요양보험제도에서 치과위생사의 방문구강위생업무 중 중요한 업무순위에 대해 1순위가 '관리적, 예방적 처치 영역', 2순위는 '구강보건교육 영역'으로 나타났다. 구강보건교육 영역 중에서 중요한 교육분야는 '잇솔질'이 79.9%로 현저히 높게 나타났으며, 예방적 처치 영역 중에서도 '잇솔질 실행'이 64.5%로 가장 높게 나타났다. 2. 치과위생사가 방문구강위생업무를 하기위해 치과의사의 지시서가 필요한 것에 대한 인지여부에서 38.2%가 '예', 61.8%가 '아니오'라고 응답하였다. '예'라고 응답한 치과위생사 중 근무경력이 '1년 이상-4년 미만'인 치과위생사가 치과의사의 지시서 필요에 대해 인지하고 있는 비율이 13.9%로 가장 높게 나타났다(p<0.05). 3. 치과위생사가 노인장기요양소를 개설할 수 있는 것을 인지하고 있는 지에 대해 93.4%가 '아니오', 6.6%가 '예'라고 응답하였다. 학력에 따른 노인장기요양소 개설의향정도는 치과위생사의 학력이 '학사'인 경우가 3.48로 가장 높게 나타났다(p<0.001). 4. 노인장기요양보험제도의 인지정도에 대한 변수 중 '방문구강위생업무 시 치과의사의 지시서가 필요한 것에 대한 인지정도'와 '노인장기요양소 개설의향정도'와의 관계에서 음(-)의 상관관계(r=-0.300)를 보여주고 있으며, 통계적으로 유의한 차이를 보였다(p<0.01). 이상의 결과로 보아 노인장기요양보험제도의 수급자에게 구강위생업무를 제공해야할 치과위생사의 인지도가 낮으므로 노인장기요양보험제도에 대하여 치과위생사들에게 적극적인 홍보와 정기적인 교육을 통하여 인지도를 높여가야 할 것으로 사료된다.
