Objectives : This study was aimed at exploring career-related characteristics of premedical students in Korean Medicine college and those relationships with career development readiness and vocational value. Methods : A total of 140 premedical students participated in the survey. The questionnaire consisted of demographic characteristics and career-related characteristics such as motive for career choice, specialty preference after college graduation, and school life adaptation. Also they responded in the web-survey of career development readiness inventory and vocational value inventory developed by Korea Research Institute for Vocational Education & Training. Eight items of motive for career choice were collected from the pilot study from 70 premedical students. Results : 'Job stability' was the top motive for career choice(25.5%). The average college life adaptation score was relatively low(13.7) : higher in male(14.3) and the early career decision group(14.2) than female (12.9) and late decision group(12.9), which was statistically significant(p=0.019 and p=0.036, respectively) in the subgroup analyses. The result of career development readiness inventory showed that 'self-knowledge' (79.3) and 'confidence on career decision' (78.6) were the two highest, which is similar to the result of the vocational value inventory ('fulfilling abilities' and 'self-improvement'). More characteristics were also described. Conclusions : The results showed that Korean Medicine premedical students have high vocational identity. This study suggested that more specified studies for identifying career-related characteristics for Korean Medical students should be conducted in order to design systematic and professional medical education programs.

Objective: The purposes of this study were to evaluate size-specific dose estimate (SSDE) of low-dose CT (LDCT) in the Korean Lung Cancer Screening (K-LUCAS) project and to determine whether CT protocols from Western countries are appropriate for lung cancer screening in Korea. Materials and Methods: For participants (n = 256, four institutions) of K-LUCAS pilot study, volume CT dose index ($CTDI_{vol}$) using a 32-cm diameter reference phantom was compared with SSDE, which was recalculated from $CTDI_{vol}$ using size-dependent conversion factor (f-size) based on the body size, as described in the American Association of Physicists in Medicine Report 204. This comparison was subsequently assessed by body mass index (BMI) levels (underweight/normal vs. overweight/obese), and automatic exposure control (AEC) adaptation (yes/no). Results: Size-specific dose estimate was higher than $CTDI_{vol}$ ($2.22{\pm}0.75mGy$ vs. $1.67{\pm}0.60mGy$, p < 0.001), since the f-size was larger than 1.0 for all participants. The ratio of SSDE to $CTDI_{vol}$ was higher in lower BMI groups; 1.26, 1.37, 1.43, and 1.53 in the obese (n = 103), overweight (n = 70), normal (n = 75), and underweight (n = 4), respectively. The ratio of SSDE to $CTDI_{vol}$ was greater in standard-sized participants than in large-sized participants independent of AEC adaptation; with AEC, SSDE/$CTDI_{vol}$ in large- vs. standard-sized participants: $1.30{\pm}0.08$ vs. $1.44{\pm}0.08$ (p < 0.001) and without AEC, $1.32{\pm}0.08$ vs. $1.42{\pm}0.06$ (p < 0.001). Conclusion: Volume CT dose index based on a reference phantom underestimates radiation exposure of LDCT in standard-sized Korean participants. The optimal radiation dose limit needs to be verified for standard-sized Korean participants.

Environmental conditions during early mammalian embryo development are critical and some adaptational phenomena are observed. However, the mechanisms underlying them remain largely masked. Previously, we reported that AQP5 expression is modified by the environmental condition without losing the developmental potency. In this study, AQP11 was examined instead. To compare expression pattern between in vivo and in vitro, we conducted quantitative RT-PCR and analyzed localization of the AQP11 by whole mount immunofluorescence. When the fertilized embryos were developed in the maternal tracts, the level of Aqp11 transcripts was decreased dramatically until 2-cell stage. Its level increased after 2-cell stage and peaked at 4-cell stage, but decreased again dramatically until morula stage. Its transcript level increased again at blastocyst stage. In contrast, the levels of Aqp11 transcript in embryos cultured in vitro were as follows. The patterns of expression were similar but the overall levels were low compared with those of embryos grown in the maternal tracts. AQP11 proteins were localized in submembrane cytoplasm of embryos collected from maternal reproductive tracts. The immune-reactive signals were detected in both trophectoderm and inner cell mass. However, its localization was altered in in vitro culture condition. It was localized mainly in the plasma membrane of the blastocysts contacting with external environment. The present study suggests that early stage embryo can develop successfully by themselves adapting to their environmental condition through modulation of the expression level and localization of specific genes like AQP11.

A variety of pattern recognition algorithms including neural networks may be applicable to the identification of odors. In this paper, an identification technique for an electronic odor sensing system applicable to wound state monitoring is presented. The performance of the radial basis function(RBF) network is highly dependent on the choice of centers and widths in basis function. For the fine tuning of centers and widths, those parameters are initialized by an ill-conditioned genetic fuzzy c-means algorithm, and the distribution of input patterns in the very first stage, the stochastic gradient(SG), is adapted. The adaptive RBF network with singular value decomposition(SVD), which provides additional adaptation capabilities to the RBF network, is used to process data from array-based gas sensors for early detection of wound infection in burn patients. The primary results indicate that infected patients can be distinguished from uninfected patients.

This study investigated the changes in the neuronal nitric oxide synthase (nNOS) and nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d) activities during food restriction in the rat brain such as cerebral cortex, cerebellum, caudate pautamen and hypothalamus. The rats were placed on a restricted feeding schedule consisting of half the ad libitum quantity for 3 days and 1, 2, 4, 6 and 9 weeks, and a free feeding schedule for 4 weeks. The loss of body weight peaked after 1 week of food restriction and persisted during the entire 9-week period of food restriction. The dramatic weight change in the first week ($12\%$) and the reduction in weight changes thereafter suggest that major adaptation changes occur early and body maintenance occurs subsequently. In the hypothalamus, the optical densities of the NADPH-d and nNOS immunoreactivities were found to be significantly higher in the 1-week and lower in the 9-week food restricted group than in the ad libitum fed control rats. In contrast, in the cerebral cortex, the optical densities of the NADPH-d- and nNOS-positive neurons were not changed significantly during the period of food restriction. This study provides the morphological evidence showing that food restriction has a significant effect on the nitric oxide synthesizing system of the hypothalamus.

The purpose of this study is to find out the specific needs of 1st graders for parents and homeroom teachers. The research questions of this study are as follows. Research question 1. What does 1st grader want from parents? Research question 2. What does the 1st grader want for the homeroom teacher? There were 31 participants. Data collection was conducted by focus group interview. Requests for parents are summarized as 'what 1st graders want from parents', and requests for teachers are summarized as 'what 1st graders want from homeroom teacher'. As the detailed topics of 'What 1st graders want from parents' are 'I have too much work to do, so I want to reduce it', 'Don't just scold me' 'Like in kindergarten, play with me' and 'I'm so hard. Take care of me'. As the detailed topics of 'what 1^st graders want from homeroom teacher.' are 'At first it was exciting', 'Scary teacher, I hate it', 'Friendly teacher, good', 'Teacher, please praise me' and 'Teacher, please teach me fun'. We revealed that the emotional support of parents and homeroom teachers is important for 1st graders to successfully adapt to elementary school.

본 연구는 사용자 중심의 3D 사이버공간인 사회적 가상세계에서 인터페이스 환경이 어떻게 초기사용자들의 성과에 영향을 미치는 지에 대해 탐색하였다. 초기의 인기에도 불구하고 사회적 가상세계는 많은 사용자들의 이탈을 경험하고 있다. 한 가지 가능한 원인은 초기사용자들에게 익숙하지 않은 사회적 가상세계의 인터페이스가 그들의 적응에 방해가 될 수 있다는 것이다. 사회적 가상세계에서 하고자 하는 작업에 대한 실패는 초기사용자들의 이탈을 가속화시킬 수 있다는 점에서, 본 연구는 인터페이스 요소들(현존감, 지원성, 피드백)의 초기사용자의 성과에 미치는 영향을 탐색하였다. 40명을 대상으로 하는 실험에서, 각 참여자는 사회적 가상세계인 세컨드라이프에서 7개의 작업을 수행한 후, 설문서에 답하였다. 실험결과, 사회적 가상세계의 지원성과 피드백은 초기사용자의 성과에 유의미한 영향을 끼치는 것으로 나타났으나 현존감은 영향이 없는 것으로 나타났다.

This study sought to figure out women's needs during early postpartum for developing adequate nursing intervention toward postpartal women's healthy adaptation. A convenience sample of 89 women who are in the early postpartal period and admitted in a university hospital located in Seoul, Korea was studied from July 1, 1999 to August 13. 1999. 1. The age group of 26-30 years was 52.8% and the level of education above high school 91%. 67.6% of women had no job, 62.9% had experienced one time of delivery, and 52.8% had no experience of abortion. 2. 31.5% of women received prenatal education, 44.9% only postpartal education. 77.5% of women planned breast-feeding, and 53.9% of women had an experience of breast-feeding during hospital stay. For the feeling of confidence related to the self-care, 27% only expressed 'yes. I have' and 59.5% 'just a little bit'. For the feeling of confidence related to the baby rearing, 29.2% only expressed 'yes. I have' and 60.7% 'just a little bit'. 3. The rate of postpartal women's mother as a preferred non-professional care giver was the highest, 75.3%. The rate of the style of Sanhujori highly preferred and planned at this time was at postpartal women's maiden home or her home with mother, 58.4%, 47.7% respectively. It shows that women still wish to have traditional Sanhuiori at home. 4. The mean of nursing need of postpartal women was 4.25% and it means that universally the degree of nursing need during postpartum is still high. General nursing need (4.29) was higher than that of traditional Sanhujori (4.09), however, the need of Sanhujori is still high. 5. Specifically, the degree of nursing need according to the category of needs was 'educational need for baby rearing,' 4.43; 'emotional-psychological care', 4.41; 'environmental care,' 4.31; 'self-care,' 4.14; and 'physical care,' 3.85 in rank. The educational need core of the specific method about Sanhuiori (4.35) was second to the highest among 15 items of self-care. 6. The related factors to the degree of nursing need were age to physical care; educational level, plan of breast feeding and experience of breast feeding during hospital stay to emotional-psychological care; and the feeling of confidence in baby rearing to environmental care. 7. There was highly positive correlation between the degree of traditional Sanhujori need and general care need(r=.77). This result strongly reflects that there is a necessity of professional care givers' capability to consider the integrative care reflecting the socio-cultural need for women's healthy adaptation during postpartum. It provides a challenge to the professional care givers to research further on the effects of Sanhuiori on the health status, health recovery after abortion or delivery from the various aspects through the cross-sectional and longitudinal research for the refinement of the reality of Sanhuiori not only as cultural phenomenon but as an inseparable factor influencing on women's postpartal healthy adaptation and for the appropriateness of intervention and quality of care for desirable health outcome.

Background: Physical exercise is known to cause significant joint changes. Thus, monitoring joint behavior of athletic horses is essential in early disorders recognition, allowing the proper management. Objectives: The aims of this study were to determine the morphological patterns, physical examination characteristics and ultrasound findings of show jumping horses in training and to establish a score-based examination model for physical and ultrasound follow-ups of metacarpophalangeal joint changes in these animals. Methods: A total of 52 metacarpophalangeal joints from 26 horses who were initially in the taming stage were evaluated, and the horses' athletic progression was monitored. The horses were evaluated by a physical examination and by B-mode and Doppler-mode ultrasound examinations, starting at time zero (T0), which occurred concomitantly with the beginning of training, and every 3 months thereafter for a follow-up period of 18 months. Results: The standardized examination model revealed an increase in the maximum joint flexion angles and higher scores on the physical and ultrasound examinations after scoring was performed by predefined assessment tools, especially between 3 and 6 months of evaluation, which was immediately after the horses started more intense training. The lameness score and the ultrasound examination score were slightly higher at the end of the study. Conclusions: The observed results were probably caused by the implementation of a training regimen and joint adaptation to physical conditioning. The joints most likely undergo a pre-osteoarthritic period due to work overload, which can manifest in a consistent or adaptive manner, as observed during this study. Thus, continuous monitoring of young athlete horses by physical and ultrasound examinations that can be scored is essential.

The purpose of study was : 1) to analyze the trend of research on the family with chronically ill children in Korea, 2) to suggest direction for future study on the family with chronically ill children, and contributing to the use of intervention in family nursing practice. Research studies on the family with chronically ill children were selected from the Korean Nusre, the Korean Nurses' Academic Society Journal, and from dissertations, which were conducted between 1975 and 1995. The total numbers of the studies were 35. These studies were analyzed for 1)time of publication or presentation, 2)research design, 3)characteristics of subjects, 4) type of chronic disease, 5)main concepts, 6)measurement tool, 7) the sis for a degree or nondegree, 8) result of correlational studies. The findings of the analysis were as follows : 1) The numbers of studies on the family with chronically ill children have increas rapidly the early 1990's. In research design, the numbers of survey research studies were the highest. Especially, the most frequently research design was the correlational survey. There were 19 correlational studies(25.7%) during the early 1990's. 2) The subjects in 16 studies(45.7%) were mother of chronically ill children and, in 8 studies (22.9% ) were their parents. 3) In most types of chronic diseases, there were 14 hematooncologic disease(32.6%) and 14 hadicapped children (32.6% ). 4) Frequently used research concepts were stress, degree of coping or way of coping, social support, parents' support, family functioning, intensity of family and family adaptation. 5) Acceding to the results of correlational studies, the more family stress was higher the more degree of coping, family functioning, intensity of family and degree of family adaption was lower. The more degree of social support was higher the more stress was lower and degree of coping, family functioning and intensity of family was higher. The more family functioning was higher the more intensity of family and family adaptation was higher. 6) 24 researches on the family with chronically ill children were done for a thesis for a degree and 11 were nondegree research studies. The following suggestions are made based on the above findings : 1) The pattern of these studies related to the family with chronically ill children in domain of Nursing need to be compared with trend in other domains. 2) More replicated research on the family with chronically ill children is needed to develop family nursing intervention and prove the effect of that and more qualitative research on the family with chronically ill children is needed to comprehensive indepth the family with chronically ill children. 3) Further research on the family with chronically ill children is needed to verify subjects and type of chronic disease, develop applicable measurement tools in Korea and identify relation between other concepts. 4) Family nursing researchers should make an effort to apply research result in various clinical settings and community settings, and try to carry out not only team research with clinical nurse but also other multidisciplinary researcher related to the family.
