This study was to explore the relationship between nurses' personality type and their job satisfaction level. The subjects of the study were the 364 nurses who were serving at the general surgical department, psychiatric department, pediatric department and emergency room. The hospitals for which they were working were four university hospitals in Daegu and Busan, and six other university hospitals in Seoul were selected as sample hospitals. For data collection, questionnaires were self-reported to the subjects, under their agreement, from May to June, 2000. The following two instruments were used in the study: One was MBTI Test whose Korean version designed and verified to reliability and validity by Kim Jung Taek and Shim Hae Sook(1990): the other was the Nursing Job Satisfaction Instrument, 'The Index of Work Satisfaction' developed by Slavitt, et al.., (1978). The data were analyzed by frequency, t-test, one-way variance analysis, scheffe's post hoc contrast, and Pearson correlation coefficient with SPSS Win 10.0 program. The results this study were as follows ; 1. As a result of testing nurse's personality type by function at each career, it's found that the most personality type was expressed by the ST-type$(37.3\%)$ at 1-5 years, the SF-type$(29.4\%)$ at 6-10 years, the ST-type$(43.3\%)$ at more than 11 years. 2. As a result of testing the disparity in job satisfaction according to career, it appeared that the 6-10 years group showed higher job satisfaction, followed by the 6-10 years$(119.6\%),\;1-5 years(118.6\%)\;and\;more\;than\; 11 years(117.7\%)$ groups. 3. As a result of testing job satisfaction level according to nurse's personality type by function at each career, it's found that the most job satisfaction was expressed by the SF-type(F=8.50, p=0.00l) at 1-5 years. the ST-type(F=30.61, p=0.001) at 6-10 years. the SF-type(F=4.98, p=0.003) at more than 11 years groups. 4. As a result of testing a significant correlation between nurse's personality type by function and job satisfaction level. the SF(r=0.279, p=0.001) and ST(r=0.222, p=0.001) types showed significant positive correlation. and the NF(r=-0.201, p=0.001) and NT(r=-0.402, p=0.001) types revealed significant negative correlation. The nursing management is likely to be done more effectively, if managers in charge of nursing administration carefully reflect nurses' personal opinions in posting and personnel management, keeping in mind that there is a specific personality type that serves to raise job satisfaction at a specific career.

The present study was aimed at investigating effects of chicory inulin and three kinds of oligosaccharides on lipid metabolism in rats fed a high-cholesterol diet. Nine Sprague-Dawley male rats weighing, about 190g were given one of five experimental diets, which were basal cholesterol diet (Control) isomaltooligosaccharide diet (IMO), Iructooligosaccharide diet (FO), chicory inulooligosaccharide diet (CIO) and chicory inulin diet (CI) for 5 weeks. In the oligosaccharide and inulin diets, 6% was added at the expense of sucrose. Rats were pair-fed to the intake of FO group which consumed the least amount, and their feces were collected during the last 4 days. Body weight gain was lower in Fo and CI groups compared with the Control group. Plasma glucose levels of FO and CIO groups were lower and plasma triglyceride concentrations of FO, CIO, and CI groups were lower than those of IMO group. Plasma cholesterol concentration did not differ among groups. Relative liver weight was lower in CIO group. Hepatic triglyceride and cholesterol did not differ among. groups. Fecal excretion of neutral steroid and bile acid were not different among groups, but fecal triglyceride excretion was significantly increased in FO and CI groups compared with the Control group. In conclusion, supplementation of oligosaccharides and chicory inulin at 6% of diets showed no significant hypolipidemic effect in rats fed a high cholesterol diet.

This paper describes the results of assessment of radiological dose resulting from operation of the Daedeok nuclear facilities including the HANARO research reactor, which has been performed to assure whether or not to comply with the regulation standards of the radioactive effluents releases. Based on the meteorological data and the radiation source term, the maximum individual doses were evaluated from 2010 to 2012. The atmospheric dispersion and the deposition factors of gaseous effluents were calculated using the XOQDOQ computer code. ENDOS-G and ENDOS-L code systems were also used for maximum individual dose calculation from gaseous and liquid effluents, respectively. The results were compared with the regulation standards for the radioactive effluents presented by the Nuclear Safety and Security Commission (NSSC). The effective doses and the thyroid doses of the maximum individual were calculated at the maximum exposed point in the Daedeok site, and contributions of exposure pathways to the radiological doses resulting from gaseous and liquid radioactive effluents were evaluated at each facility of the Daedeok site. As a result, the maximum exposed age was analysed to be the child group, and the operation of HANARO research reactor had a major effect more than 90% on the individual doses. The main exposure pathways for gaseous radioactive effluent were from ingestion and inhalation. The effective doses and the thyroid doses were considerably influenced by tritium and iodine, respectively. The gaseous radioactive effluents contributed more than 90% on the total doses, whereas the contributions of the liquid radioactive effluents were relatively low. Consequently, the maximum individual dose due to radioactive effluents from the nuclear facilities within the Daedeok site were less than 3% of the regulation standard over 3 years; therefore, it can be concluded that radioactive effluents from the nuclear facilities were well managed, with the radiation-induced health detriment for residents around the site being negligible.

To achieve this objective, practical problem-teaching lesson plans and instructor-led teaching and learning plans were developed and integrated into the Technology Home Economics, and Human Development curricula at both academic and vocational high schools. The impact of these plans was examined, as were connections between the teaching methods and types of schools. As part of this study, a survey was conducted on 1,263 students in 46 classes at 6 randomly selected high schools: 4 academic and 2 vocational. A total of 9 teachers conducted classes for both experimental and comparative groups between October 2009 and November 2010. Pre- and post-tests were used to study the impact of the lessons on the experimental and comparative groups. In terms of data analysis and statistics processing, this study implemented mean and standard deviations, t-test, and analysis of covariance using the SPSS 12.0 program. The results of this study are as follows. The practical problem-teaching lessons produced more positive results in the students than the instructor-led lessons, in terms of their image of the elderly, their level of knowledge about them, their understanding of their need for welfare services, and preparation for Successful aging. When comparing the results by type of school, the experimental groups at academic high schools appeared to have a more positive image and better understanding of the elderly and their need for welfare services, and were better prepared for Successful aging than during their previous lessons. They also showed an increase in independence from their children in aging. As for the comparative groups, students at academic high schools showed an increase in preparation for Successful aging compared to the previous lessons. Finally, as for future research on preparation for aging in high schools, more schools should include this subject in their regular curriculum for Technology Home Economics, Human Development and Home Economics in order to generalize the results, and they need to evaluate the content. Additionally, this study suggests that new high school curricula should include lessons on preparation for aging so that students can deal successfully with our aging society.

This study investigated the Present status of laboratories for experiment and practice, and analyzed teachers' recognitions on experiment and practice for Home Economics area of a Technology and Home Economics curriculum according to majors of teachers. Questionnaires were mailed to middle school teachers who taught home economics part and they answered on the web. 220 replies were used for the final analysis. The findings were as follows: First, the facilities and teaching equipments of laboratories for home economics area were inferior, especially, for clothing and textiles part and housing part. Second, teachers recognized necessity to conduct experiment and practice highly. Food life part scored the highest, while housing part scored the lowest. Teachers who majored in home economics recognized more necessities of experiment and practice than teachers who didn't majored in home economics. Third, they recognized level of experiment and practice to be suitable to students, but 'maintenance and repair of housing' section was relatively less suitable than other sections. Fourth, 'making clothes and recycling' section was recognized to have the least suitability in quantities and hours of experiment and practice lesson, because of too much contents and lack of lesson hours. Fifth, teachers recognized that students were more interested in 'the basis of food preparation and practice' section, but they are less interested in 'maintenance and repair of housing' section. Sixth, teachers recognized that contents of experiment and practice were very useful to the real life. 'The basis of food preparation and practice' section was the most useful, while 'maintenance and repair of housing' section was the least useful. Seventh, experiment and practice lessons for food life part were put in practice very well, followed by the order of clothing and textiles part and housing part. Teachers who majored in home economics usually took more experiment and practice lessons than teachers who didn't major in home economics.

The purpose of this study was to prepare low methoxyl pectins (LMPs) by pectinesterase (PE) using waste tangerine peels and to compare the chemical, physical and gelling properties of the prepared pectins with the commercial LMP. The LMPs were prepared by treating albedo with 0.25M $Na_2CO_3$ to activate the PE. PE was then inactivated by heating. The sample was centrifuged and the supernatant was collected. LMP was obtained as precipitate by adding alcohol to the collected supernatant. The amounts of extractible pectins in albedo were 12.71~12.98% on a dry weight basis. Methoxyl contents of LMPs prepared by treating albedo with PE at pH 7.5 for 10min, at pH 8.5 for 10min, 20min and 30min were 5.12%, 4.27%, 3.08%, 1.85% respectively, demonstrating that the methoxyl contents of the preparations decreased as the degree of treatment albedo with PE increased. The acetyl contents of the preparations ranged from 0.09% to 0.12%, the values of which do not interfere with gel formation. The anhydrouronic acid contents of the prepared pectins were in the range of 94.2%~94.8%. The values of viscosity and molecular weights of the prepared LMPs tent to decrease as the degree of PE action on albedo increased. The textural value of the prepared LMP gels determined by Consistometer, Ridgelimeter and Instron denonstrated that the excess treatment of albedo with PE significantly impaired the gelling properties of the preparations.

The present study investigated the effect of Sinetrol-XPur (polyphenolic Citrus spp. and Paullinia cupana Kunth dry extract) and defined the action mode for cyclic adenosine monophosphate (cAMP)-dependent uncoupling protein (UCP)-2 activation. Leptin-deficient obese mice were treated with two different doses, 100 mg/kg body weight (BW) and 300 mg/kg BW of each AIN93G supplement, for 7 weeks. Treatment of obese mice with both low and high doses of Sinetrol-XPur significantly reduced body weight gain compared to control obese mice. White adipose tissue weight of mice was reduced by 30.96% in high dose-supplemented groups. Serum total cholesterol and triglyceride were reduced by a high dose of Sinetrol-XPur by 20.02% and 30.96%, respectively. Serum level of high density lipoprotein (HDL) was significantly increased by treatment with both doses, as the ratio of HDL to low density lipoprotein increased by 138.78% and 171.49%, respectively. Regarding expression of biochemical factors related to lipid metabolism, fatty acid synthase significantly decreased and UCP-2 increased upon treatment with a high dose of Sinetrol-XPur, but there was no significant difference in lipoprotein lipase and hormone-sensitive lipase. To define cellular mechanism, intracellular cAMP levels in 3T3-L1 adipocytes significantly increased in a dose-dependent manner over the range of $50{\sim}250{\mu}m/mL$. The phosphodiesterase (PDE) inhibitor 3-isobutyl-1-methylxanthine clearly blocked cAMP, suggesting that Sinetrol-XPur promotes lipolysis of adipocytes through inhibition of cAMP-dependent PDE, resulting in induction of cAMP response element binding protein and UCP-2. These results suggest that Sinetrol-XPur supplementation is a viable option for reducing body weight and fat by improving serum lipid profiles and genetic expression of lipid metabolic factors, especially activation of cAMP-dependent UCP-2.

According to statistics, it is shown that domestic SMEs rely on bank loans for the majority of fund procurement. From financial information shortage (Thin file) that does not provide information necessary for credit evaluation from banks such as financial statements. In order to overcome these problems, recently, in alternative finance such as P2P, using differentiated information such as demographics, trading information and the like utilizing Fintech instead of existing financial information, small funds A new credit evaluation method has been expanding to provide SMEs with small amounts of money. In this paradigm of environmental change, in this research, credit evaluation which can expand fund supply to SMEs by utilizing big data based on trade area information such as sales fluctuation, location conditions etc. In this research, we try to find such a solution. By analyzing empirically the big data generated in the trade area, we verify the effectiveness as a credit evaluation factor and try to derive the main parameters necessary for the business performance evaluation of the founder of SMEs. In this research, for 17,116 material businesses in Seoul City that operate the service industry from 2009 to February 2018, we collect trade area information generated for each business location from Big Data specialized company NICE Zini Data Co., Ltd.. We collected and analyzed the data on the locations and commercial areas of the facilities that were difficult to obtain from SMEs and analyzed the data that affected the Corporate financial Distress. It is possible to refer to the variable of the existing unused big data and to confirm the possibility of utilizing it for efficient financial support for SMEs, This is to ensure that commercial lenders, even in general commercial banks, are made to be more prominent in one sector of the financing of SMEs. In this research, it is not the traditional financial information about raising fund of SMEs who have basically the problem of information asymmetry, but a trade area analysis variable is derived, and this variable is evaluated by credit evaluation There is differentiation of research in that it verified through analysis of big data from Trading-area whether or not there is an effect on.

In order to evaluate the radio-protective advantage of an enhanced dynamic wedge (EDW) over a physical wedge (PW), we measured peripheral doses scattered from both types of wedges using a 2D array of ion-chambers. A 2D array of ion-chambers was used for this purpose. In order to confirm the accuracy of the device we first compared measured profiles of open fields with the profiles calculated by our commissioned treatment planning system. Then, we measured peripheral doses for the wedge angles of $15^{\circ},\;30^{\circ},\;45^{\circ},\;and\;60^{\circ}$ at source to surface distances (SSD) of 80 cm and 90 cm. The measured points were located at 0.5 cm depth from 1 cm to 5 cm outside of the field edge. In addition, the measurements were repeated by using thermoluminescence dosimeters (TLD). The peripheral doses of EDW were (1.4% to 11.9%) lower than those of PW (2.5% to 12.4%). At 15 MV energy, the average peripheral doses of both wedges were 2.9% higher than those at 6MV energy. At a small SSD (80 cm vs. 90 cm), peripheral dose differences were more recognizable. The average peripheral doses to the heel direction were 0.9% lower than those to the toe direction. The results from the TLD measurements confirmed these findings with similar tendency. Dynamic wedges can reduce unnecessary scattered doses to normal tissues outside of the field edge in many clinical situations. Such an advantage is more profound in the treatment of steeper wedge angles, and shorter SSD.
