For the purpose of investigating the effect of evaluation on career support by the college and career exploration efficacy of dental hygiene students on the career exploration behavior, a survey was conducted in December 2014 with students of dental hygiene at universities located in Ulsan and Daegu as subjects. In the result, correlation was found among sub-factors of evaluation on career support by the college, career exploration efficacy, and career exploration behavior. Increase of career exploration efficacy (${\beta}=0.702$, p<0.001), practical career support (${\beta}=0.165$, p<0.05), and relationship establishment efficacy (${\beta}=0.152$, p<0.05) led to increase of career exploration behavior, while increase of individual exploration efficacy (${\beta}=.0.242$, p<0.001) led to decrease of career exploration efficacy. Therefore, it is necessary to build appropriate value system related to job seeking, conduct active discussions to increase relationship establishment efficacy by using interpersonal relationship reinforcement program, and expand career support program by the college.

Fungal occurrence during production of dried red pepper was investigated using red pepper samples collected at harvest, before and after washing, and before, during or after drying. Fungal incidence was evaluated by counting the number of fungal colonies grown after incubating random pepper cuts on potato dextrose agar plates. Washing with ground water had no significant effect on reduction of fungal contamination. Fungal increase was observed in some samples, and the insides of washer and containers were contaminated with fungi. Drying caused significant fungal increase regardless of drying method although the fungal incidence after machine drying was lower than that after greenhouse drying. Fungal increase was observed in the samples being dried in a greenhouse and some mycotoxigenic species were also detected. Therefore, the most important control point for fungal contamination during dried pepper production appears to be the drying process, especially in a greenhouse.

Purpose : Pulmonary vascular hypertension is a common problem in congenital heart disease, the most common cardiac condition in childhood. However, the mechanisms responsible for this pathologic change, treatment, and prevention are poorly understood. Therefore, we studied the gene expression of vascular endothelial growth factor(VEGF) by using a hypoxic model of the pulmonary artery smooth muscle cells. Methods : The main pulmonary artery and its proximal branches of a 6 wk old Fischer rat were excised. They were cut into multiple small pieces and suspended in DMEM medium supplemented with 20% fetal bovine serum and incubated in 5% $CO_2$-95% air atmosphere. The smooth muscle cells were confirmed by immunostaining with smooth muscle myosin and ${\alpha}$-smooth muscle actin antibodies. The VEGF gene expression in the hypoxic group was compared with the one in control the group as well as the one in the starved group by RT-PCR and Northern blot hybridization. Results : There was no statistically significant difference among the control, hypoxic and starved groups. Conclusion : There are few studies of pulmonary vascular hypertension at the molecular level in Korea. Therefore, we studied the expression of VEGF gene in hypoxic pulmonary vascular smooth muscle cells. Further studies will be needed to find the difference between newly born and adult rats, or human and rat pulmonary vascular smooth muscle cells in gene expression. We hope that the study will lead to a better understanding of pulmonary vascular hypertension.

A 47-year-old female was admitted for an evaluation of a left mediastinal mass. The chest X-ray performed 16 months ago was normal, but the chest X-ray upon admission showed a large mass adjacent to the anterior aspect of the left hemidiaphragm. The CT scan demonstrated a large mass with a fat density in the left lower hemithorax. A focal diaphragmatic defect behind the xiphoid process was suspected. A thoracoscopic examination revealed omental herniation through the diaphragmatic defect. Therefore, a left thoracotomy was performed and the defect was repaired. We believe that a differential diagnosis should be needed to include a diaphragmatic omental hernia when a fat density mass is observed in the mediastinum.

Methylmercury, an organic derivative, is the principal form of mercury that biomagnifies and causes neurodegenerative symptoms in animals. In recent years, living modified organism (LMO) resulting from biotechnology has played a highly visible and controversial role. Despite the potential benefits of this technology, public concerns have been raised about the environmental risk of LMO. The concern on the risk from LMO release has urged efforts to evaluate and manage the risks of the LMO. To build up the capacity building of risk assessment method for LMO used environmental remediation, we engineered Solanum nigrum L, expressing the modified bacterial gene, merB, encoding organomercurial lyase. Two independently isolated transgenic lines produced merB RNA. Transgenic Solanum nigrum leaf discs expressing merB gene showed organic mercury resistance, forming shoots well on growth medium containing $0.5{\mu}M$ methylmercury (II) chloride and $1{\mu}M$ phenylmercuric acetate while control plants breached. Transgenic merB seeds germinated and grew on growth medium containing $2{\mu}M$ methylmercury (II) chloride and phenylmercuric acetate. The merB transgenic plants will be used for risk assessment of natural environment.

For making something to use as a tool since the emergence of mankind, the initial pragmatic purpose has transformed into a new genre of art over time. Things defined like this have rooted in our culture as tradition so far. In the midst of today's various trends, a reflection of tradition and a modern search for tradition by re-creating it are much more needed. To any people in any time, a new trend would undeniably develop on the basis of its previous tradition in any form. The colors appearing in such artwork are also an expression of each people's unconscious potentiality as essential grounds for human aesthetic. The traditional Korean Bojaki, which was made out of women's pragmatic mind trying to recycle trashy pieces of cloth in the 19th century of Chosun Dynasty, appears as a symbolization of our nation's original form in unconsciousness. It includes Confucianism, Buddhism, Zen and the Yin-Yang and Five Elements thought, which have been together with naturalism. The five colors appearing in the Yin-Yang and Five Elements are the basis. Fourteen selected samples around the five colors seen in the color scheme of the Chosun era's Bojaki were measured and their color values were found by analyzing them based on HCV(Hue, Chroma, Value)of the five primary colors as well as the five secondary colors. After choosing a few colors with bare eyes close to traditional Primary Colors and Secondary Colors amongst 14 pieces of data which particularly used traditional Five Colors and examining them using spectrophotometer(JX777), the following conclusions were drawn. Comparing only colors in Primary Colors, the result was red 7.11R 4.59/10.69, blue 6.71PB 3.18/6.45, yellow 3.91Y 7.56/6.12, respectively. With regard to Secondary Colors, it was reported that red 7.96RP 5.42/10.3, blue 7.8B 5.16/5.53, green 8.03GY 6.05/4.34, yellow 2.73Y 7.47/4.07, purple 2.39RP 4.69/4.56, respectively. (diagram) As a result, the standard of Five Colors can be used in modern fiber color. There are differences in dyeing material, methods and kinds of fiber of that time, but women of Chosun Dynasty combined and made fabric which was circulated. Consequently, an applicable attribute of the aye-color values was considered.

The purpose of this study is to inquire into the degree of health promotion activity of university students, and to confirm the general factors of health promotion behavior in order to offer basic data for a nursing strategy to improve health promotion behavior. For this research, data was collected from university men and women through questionnaires from February 18 to March 20 in 1998. The author develop a measuring instrument on the basis of related reviews of health promoting behavior in the prevention of chronic disease, as well as accounting for demographic factors, biological factors, and circumstanctial factors. The content validity of the instrument was authenticated by two professors of the science of nursing,. and the reliability was confirmed by a 'cronbach' ${\alpha}'$ after moditying the content through a pre-test on 30 students. 475 persons were analyzed in terms of an average, percentage, t-test, ANOVA by 'SPSS-PC'. The analyzed data was the following. 1. The acting degree of health promoting behavior was 3.26 point out of 6. Among the sub-levels of health promoting behavior, the order of importance was the following. self-actualization (4.62), interpersonal(4.60), stress management (4.0l), nutrition(3.68), responsibility(3.1l), liquid and cigaretles ues(2.85), and exercise (2.33). 2. The differences in health promoting behavior according to subject's general character were the following. Age(F=6.012, p=.003), major (F=7.243, P=.000), sex(t=7.60, P=.000), religion(F=2.454, p=.045), living status(F= 2.849, p=.024), health concern of parents(F= 7.596, P=.000), taking health programs(F= 2.710, p =.007), case history of the family( t = -1.980, p=.048). Health promoting behavior is affected by a higher age, majoring in the social sciences, having religion, male, living in the relatives' home, having to take health programs and a higher health concern of the parents. Suggestions: 1. The degree of health promoting behavior appears low in this study. It is crucial, therefore, to develop a health program to improve health promoting behavior and to study how to center the daily health life of students.

The purpose of the study is to enhance the figure analysis ability for pre-service elementary teacher by using GSP. To do this, we limited to teaching competence divide into ability various problem-solving, extract key elements, predict the difficulty of student and investigated the initial of them, the reality of GSP construction. As results, pre-service elementary teachers made errors, proposed teaching focused on the character using in the problem solving, and found that in one particular difficulties to find the students. The reality of GSP construction activity was possible to explore through the partially constructed a number of various properties, but we found to have difficulty in the connection between concepts. and integrated view of the problem analysis. After visual identification and exploration through the GSP construction, problem-solving ability became a little more variety and changed their direction in order to focus the student's anticipated difficulties. From these results, we could extract some pedagogical implications helping pre-service teachers to reinforce teaching competence by GSP construction.

Recently, the consumption of dietary supplements has increased because of people’s greater interest in health. Unfortunately, the sales of dietary supplements containing unauthorized substances such as drugs have also increased. We developed a rapid, accurate method for the simultaneous determination of antihistamines using liquid chromatography tandem mass spectrometry with a multiple reaction monitoring mode. The limit of detection (LOD) and limit of quantification (LOQ) of the instrument used in this method were in the ranges 0.0003-0.3 and 0.0009-0.6 µg mL⁻¹, respectively. The linearity of the method was > 0.99. The precision levels of the method were 0.1-9.8% (intra-day) and 0.3-9.6% (inter-day), and the levels of accuracy of the method were 82.7-115.0% (intra-day) and 84.3-113.0% (inter-day). The mean of recovery of the method was in the range of 83.9-117.9% and the RSD of the stability was less than 5.9%.

The aim of this study was to assess the association of metabolic syndrome and Vitamin D in Korean adults. The study subjects were Korean menopausal woman (n=4,340) who participated in the Korea National Health and Nutrition Examination Survey 2010~2012. After adjusting for factors such as age, body mass index, total cholesterol, smoking, and regular exercise, the mean 25(OH)D levels ($M{\pm}SE$) decreased with increasing metabolic syndrome score (MSS) (MSS 0, $18.18{\pm}0.29ng/Ml$; MSS 1, $18.09{\pm}0.21ng/mL$; MSS 2, $18.07{\pm}0.19ng/mL$; MSS 3, $18.04{\pm}0.21ng/mL$; MSS ${\geq}4$, $17.27{\pm}0.23ng/mL$), and the mean 25(OH)D level ($M{\pm}SE$) for metabolic syndrome ($17.66{\pm}0.16ng/mL$) decreased in comparison to non-metabolic syndrome ($18.11{\pm}0.14ng/mL$). In conclusion, our results suggest that an increase in metabolic syndrome score or metabolic syndrome are inversely associated with the vitamin D levels.
