Purpose: This study observes the degrees of perfectionism (both self-oriented and socially-prescribed perfectionism), academic resilience, and satisfaction with major in nursing students and identifies the influence of perfectionism and academic resilience on satisfaction with major. Methods: Data from 115 second or third-year students in a nursing were collected for two months at different three universities. The data were analyzed with descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation coefficient, and hierarchical multiple regression. Results: Satisfaction with major was higher for second year students compared to third year students. And the satisfaction was higher for those with a higher Grade point average (${\geq}_-3.5$) compared to those with a lower. Self-oriented perfectionism had a higher score than socially-prescribed perfectionism and academic resilience based on self-control was rated the highest score of the subcategories. The degree of satisfaction was positively correlated with Self-oriented perfectionism and academic resilience. The final regression model showed that grade and academic resilience accounted for 34.2% of the variance in predicting the level of satisfaction with major. Conclusion: The results suggest that it is crucial to find a strategy that could enhance academic resilience, especially designed for upper-year university students, to improve the level of satisfaction with major.

This study is conducted to suggest ways to mitigate the mismatch phenomenon between job seekers who want to find right company for themselves and companies looking for appropriate new employees. For this purpose, this study improves the company assessment framework reflecting job seekers interests by using fuzzy analytic hierarchy process. The improved evaluation framework is a three-level hierarchical structure, where there are 4 groups at the top level, 12 factors at the intermediate level and 36 indexes at the bottom level. For the empirical analysis of the applicants preferences based on the improved model, a survey for F-AHP analysis is carried out to university students and then priorities of components in the evaluation model are calculated. Moreover, the differences of priority of the company assessment framework are analyzed for different genders, college years, and major divisions. The results show that job seekers' most concerning factors are wages, stability, working environments, and labor deal, which are ranked highly in this order and the differences in preferences for each type of job seekers (genders, college years, and major divisions) are obvious. The results also show that the male prefers wages to environment, on the other hand female does working environment to wages.

Purpose : The aim of this study is to analyse the research productivity of SCI publications at medical schools in Korea. Methods: We collected the 5,386 SCI publications from 10 medical schools that were published in 2002 and 2003. Most of the materials treated herein are derived from the database of the Institute of Scientific Information from April 13, to May 25, 2005. Values are analyzed by medical school, major and IF index and presented as frequency and percentages. Results : There were 2,350 publications in 2002 and 3,036 publications in 2003. The average publication rate per faculty was .71 in 2002 and it was increased to .90 in 2003. Of the total 5,386 manuscripts, 1.248(23.2%) papers were from work conducted at basic science department and 3,224(76.8%) were from work performed at clinical science department. The major such as pathology, microbiology, pharmacology, internal medicine, diagnostic radiology and dermatology published a lot of SCI papers. A large percentage of papers (41.74%) were in journals with reported l<=IF<3. Conclusions : There was wide variability in the research productivity among the medical schools or majors. This variability reflects the importance of the institutional characteristics of each medical school in predicting the research productivity. Some of these institutional characteristics include the size of the faculty. available research funding, research vision of medical school, visible system of measurement and any associated reward system.

The purpose of this study was to investigate the effects of nutrition education on nutrition knowledge, dietary attitudes, and food behavior of college students. The subjects of this study were 350 college students attending a university. The education group students received nutrition education three hours per week during a 4-week period offered in a 'Home Economics' course. A total of 150 students in the education group and 200 students in the non-education group completed pre-test questionaires examining nutrition knowledge, dietary attitudes, and food behaviors. Major findings were as follows : nutrition knowledge, and food behavior of the education group were improved compared to the non-education group. But significant changes were not observed in dietary attitudes in the education group. There were higher correlations between nutrition knowledge and dietary attitudes score, and between dietary attitudes and food behavior score at the posttest than those at the pretest. These results suggest that nutrition education for college students can effectively improve their nutrition knowledge and food behaviors.

As high-rise buildings become more and more slender and flexible, the wind effect has become a major concern to modern buildings. At present, wind engineering for high-rise buildings mainly focuses on the following four issues: wind excitation and response, aerodynamic damping, aerodynamic modifications and proximity effect. Taking these four issues of concern in high-rise buildings as the mainline, this paper summarizes the development history and current research progress of wind engineering for high-rise buildings. Some critical previous work and remarks are listed at the end of each chapter. From the future perspective, the CFD is still the most promising technique for structural wind engineering. The wind load inversion and the introduction of machine learning are two research directions worth exploring.

Sunlight, and in particular its UV component, is the major environmental trigger that underlies the major signs of human skin and skin cancer in general. Therefore, this study was carried out to investigate the UV protection effects of R. coreanus. R. coreanus was extracted by ultra high pressure extraction process at 500 MPa and $30^{\circ}C$ for 5 and 15 minutes. The cytotoxicity of the extracts extracted by ultra high pressure process on human dermal fibroblast cell CCD-986sk, human kidney normal cell HEK293, and human lung normal cell HEL299 was measured as 17.5%, 16.5% and 14.0%, respectively in adding $1.0\;mg/m{\ell}$ of the samples, which was much lower than that from conventional water extraction method at $100^{\circ}C$ as 23.2%, 22.5%, 21.2%. The secretion of $NO^-$ from macrophage showed $15.9\;{\mu}M$ on the R. coreanus extract from this process, which was higher than others. Prostaglandin $E_2$ ($PGE_2$) production from UV-induced human skin cells was also greatly decreased down to $510\;pg/m{\ell}$, compared to the control. From the results, we considered that the extracts from R. coreanus could be potent natural materials for skin anti-inflammation agent, and could be used as a potential anti-aging for the photo-damaged skin.

Background: The type and regimen of anesthesia may affect perioperative hyperglycemia following major surgical stress. This study compared the effects of sevoflurane and propofol on the incidence of hyperglycemia and clinical outcomes in diabetic patients undergoing lung surgery. Methods: This retrospective study included 176 patients with type 2 diabetes mellitus who had undergone lung surgery. Blood glucose levels and clinical outcomes from the preoperative period to the first 2 postoperative days (PODs) were retrospectively examined in patients who received sevoflurane (group S, n= 87) and propofol (group P, n=89) for maintenance of general anesthesia. The primary endpoint was the incidence of persistent hyperglycemia (2 consecutive blood glucose levels >180 mg/dL [10.0 mmol/L]) during the perioperative period. The secondary composite endpoint was the incidence of major postoperative complications and 30-day mortality rate after surgery. Results: Blood glucose levels similarly increased from the preoperative period to the second POD in both groups (p=0.857). Although blood glucose levels at 2 hours after surgery were significantly lower in group P than in group S (p=0.022; 95% confidence interval for mean difference, -27.154 to -2.090), there was no difference in the incidence of persistent hyperglycemia during the perioperative period (group S, 70%; group P, 69%; p=0.816). The composite of major postoperative complications and all-cause in-hospital and 30-day mortality rates were also comparable between the two groups. Conclusion: Sevoflurane and propofol were associated with a comparable incidence of perioperative hyperglycemia and clinical outcomes in diabetic patients undergoing lung surgery.

In hepatoblastoma, encouraging cure rates have been achieved with recent advances in chemotherapy and surgical techniques, The aim of this study is to evaluate the role of combined therapeutic modalities and surgical resection in hepatoblastoma. Fifteen cases of hepatoblastoma were treated from January 1993 to August 2000. Six patients had resectable tumors at initial diagnosis. All underwent surgical resection and in four patients postoperative adjuvant chemotherapy was needed. Nine out of 15 patients had unresectbale tumors at initial diagnosis, and preoperative chemotherapy was applied. There was one operative mortality and 14 patients showed good prognosis after surgery. Although various treatment modalities should be combined for the unresectable hepatoblastoma. surgical resection remains the major curative procedure.

The research examines individual environmental characteristics, the consciousness energy conservation and behavior level of college students that relate to the experience of taking courses on residential energy use held in college, as well as the influence of experiencing school education in the past. This is to ultimately evaluate the effect of school education on the consciousness of the energy conservation and behavior level of college students at present time, in order to assist in proposing a direction for the school education on residential energy use. The results of the research can be summarized as follows: First, there appeared a gap between the group that has attended courses on residential energy use and the group that has not in terms of their major, school year and the level of consciousness of the need for energy conservation. Second, students that have attended courses on residential energy use in college were reported to have received more training in high school through textbooks and guidance of teachers and have more experience in special education. And third, it appeared that taking courses in residential energy use by college students are influenced by personal factors such as their school year and gender, major, contents of their high school textbooks and the level of consciousness of the need for energy conservation.

Objective: This study evaluated the effects of a traditional Chinese medicine formula (TCMF) on muscle fiber characteristics in finishing pigs and the effects of the formula's extract (distilled water, ethyl acetate and petroleum ether extraction) on porcine cell proliferation and isoforms of myosin heavy chain (MyHC) gene expression in myocytes. Methods: In a completely randomized design, ninety pigs were assigned to three diets with five replications per treatment and six pigs per pen. The diets included the basal diet (control group), TCMF1 (basal diet+2.5 g/kg TCMF) and TCMF2 (basal diet+5 g/kg TCMF). The psoas major muscle was obtained from pigs at the end of the experiment. Muscle fiber characteristics in the psoas major muscle were analyzed using myosin ATPase staining. Cell proliferation was measured using 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) dye and cytometry. Isoforms of MyHC gene expression were detected by real-time quantitative polymerase chain reaction. Results: The final body weight and carcass weight of finishing pigs were increased by TCMF1 (p<0.05), while the psoas major muscle cross-sectional area was increased by TCMF (p<0.05). The cross-sectional area and diameter of psoas major muscle fiber Ι, IIA, and IIB were increased by TCMF2 (p<0.05). The cross-sectional area and fiber diameter of psoas major muscle fiber IIA and IIB were increased by diet supplementation with TCMF1 (p<0.05). Psoas major muscle fiber IIA and IIB fiber density from the pigs fed the TCMF1 diet and the type IIB fiber density from the pigs fed the TCMF2 diet were lower compared to pigs fed the control diet (p<0.05). Pigs fed TCMF2 had a higher composition of type Ι fiber and a lower percentage of type IIB fiber in the psoas major muscle (p<0.05). The expression levels of MyHC Ι, MyHC IIa, and MyHC IIx mRNA increased and the amount of MyHC IIb mRNA decreased in the psoas major muscle from TCMF2, whereas MyHC Ι and MyHC IIx mRNA increased in the psoas major muscle from TCMF1 (p<0.05). Peroxisome proliferator-activated receptor ${\gamma}$ $coactivator-1{\alpha}$ and CaN mRNA expression in the psoas major muscle were up-regulated by TCMF (p<0.05). Porcine skeletal muscle satellite cell proliferation was promoted by $4{\mu}g/mL$ and $20{\mu}g/mL$ TCMF water extraction (p<0.05). Both $1{\mu}g/mL$ and $5{\mu}g/mL$ of TCMF water extraction increased MyHC IIa, MyHC IIb, and MyHC IIx mRNA expression in porcine myocytes (p<0.05), while MyHC Ι mRNA expression in porcine myocytes was decreased by $5{\mu}g/mL$ TCMF water extraction (p<0.05). Porcine myocyte MyHC Ι and MyHC IIx mRNA expression were increased, and MyHC IIa and MyHC IIb mRNA expression were down-regulated by $5{\mu}g/mL$ TCMF ethyl acetate extraction (p<0.05). MyHC Ι and MyHC IIa mRNA expression in porcine myocytes were increased, and the MyHC IIb mRNA expression was decreased by $1{\mu}g/mL$ TCMF ethyl acetate extraction (p<0.05). Four isoforms of MyHC mRNA expression in porcine myocytes were reduced by $5{\mu}g/mL$ TCMF petroleum ether extraction (p<0.05). MyHC IIa mRNA expression in porcine myocytes increased and MyHC IIb mRNA expression decreased by $1{\mu}g/mL$ in a TCMF petroleum ether extraction (p<0.05). Conclusion: These results indicated that TCMF amplified the psoas major muscle cross-sectional area through changing muscle fiber characteristics in finishing pigs. This effect was confirmed as TCMF extraction promoted porcine cell proliferation and affected isoforms of MyHC gene expression in myocytes.
