The purpose of this study was to investigate the effects that body composition, nutrient intake, and biochemical indices have on skin status, as well as their associations with skin health status, by assessing 44 female university students. The subjects were classified into 3 groups according to skin sensitivity: sensitive skin (n=11), slightly sensitive skin (n=24), and normal skin (n=9). The study included anthropometric measurements and body composition analyses, dietary intake evaluations, blood chemical analyses, and skin health status assessments. Based on % body fat, the results indicated the subjects were moderately obese (29.6%). Obesity indices were not different among the groups, but the sensitive skin group tended to have higher skinfold thickness. Dry skin was determined as the skin type of all subjects. In the sensitive skin groups, U-zone and T-zone sebum were significantly lower (p<0.05), and spots were significantly higher (p<0.05) than in the normal skin group. In terms of nutrient intakes, the sensitive skin groups consumed significantly lower amounts of P and vitamins A and E (p<0.05). There were no significant differences in serum lipid fractions or total antioxidant status among the groups. In correlation coefficients analysis, skin elasticity had significant negative correlations with subscapular and midaxillary skinfold thickness, body protein, and body minerals (p<0.05). Wrinkling had positive correlations with triceps and thigh skinfold thickness (p<0.05). Skin evenness had negative correlations with energy intake, vitamins A, $B_1,\;B_2$, C, E, niacin, and zinc (p<0.05), as well as folate and P (p<0.01) and vitamin $B_6$ (p<0.001). A similar correlation tendency was observed for spots and nutrient intake, showing negative correlations with vitamins A, $B_6$, and E, as well as folate, Fe, and P. U-zone sebum showed significant positive correlations with serum levels of total cholesterol and triglycerides. From these findings, skin health status appears to be affected by both nutrient intake and body composition. Therefore, having a proper balance between dietary intake and body composition may influence skin health status in females with sensitive skin.

Data were collected from 310 6th, 7th, and 8th grade students and parents by questionnaires and analyzed by t-test and multiple regression analysis. The higher parents attachment and parents monitoring, the higher prosocial behavior towards parents and siblings, the higher perspective-taking, the higher prosocial behavior towards parents, and the higher socioeconomic status, the higher prosocial behavior towards siblings. More prosocial behavior toward parents was reported by girls than by boys. Prosocial behavior toward siblings did not show a gender difference. In the total group, high parent attachment and perspective-taking predicted prosocial behavior towards parents; high parent attachment and socioeconomic status predicted prosocial behavior towards siblings. In the boy group, high parent attachment and perspective-taking predicted prosocial behavior towards parents; high socioeconomic status predicted prosocial behavior towards siblings. In the girl group, high parent attachment predicted prosocial behavior towards parents and high parent attachment and socioeconomic status predicted prosocial behavior towards siblings. Discussion focused on the relative importance of parents attachment, perspective-taking, and socioeconomic status in predicting early adolescents' prosocial behavior.

How to improve the cell culture method on scaffolds is important in the tissue engineering fileld. In this study, we optimized seeding and culture methods to vascular smooth muscle cells (VSMCs) on biodegradable polymer scaffold. The primary culture of VSMCs obtained from canine external jugular vein was accomplished by applying the explant-derived method. The primary cultured VSMCs were seeded into scaffolds and then cultured by using various different methods; static or dynamic seeding, static or dynamic culture. The difference in proliferative response of VSMCs was analyzed with an alamar blue assay. Cell-polymer construct was examined by histochemical method and scanning electron microscopy. Mesh type scaffold ($10 \times 10 \times0.4 mm$) was made of polyglycolic acid (PGA) suture thread. The PGA mesh type scaffold was 45% in porosity, and 0.03 g in weight. The primary cultured VSMCs were confirmed with immunohistochemical staining using monoclonal anti-$\alpha$-smooth muscle actin. The density and distribution of proliferated VSMCs within the scaffold and cellular adherence on the surface of the scaffold showed better results in the static seeding condition than in the dynamic condition. Under the same condition of seeding method as the static condition, the dynamic culture condition showed enhanced proliferation rates of the VSMCs when compared to the static culture condition. In conclusion, to improve the VSMCs proliferation in vitro, static seeding is better than the dynamic condition. In the culture condition, however, culture under the dynamic status is better than the static condition. This was a pilot study to manufacture artificial vascular vessel by tissue engineering.

The purposes of this study were to describe the effects of perception of organizational culture type and job satisfaction on university hospital nurses' innovation behavior. A survey was conducted with 418 respondents working in a university hospital in Cheonan City. Organizational culture types (developmental, group, rational, hierarchical), job satisfaction and individual characteristics were surveyed. The relationships between each variable and the innovation behavior were analyzed by univariate analysis and the independent effects of these variables were examined with multiple regression. The mean score of general employees innovation behavior was 3.33 (p=.58) and that of managers was 3.53(p=.64). For general employees, there were statistically significant differences in innovation behavior according to education level. For managers, there were statistically significant differences in innovation behavior for education level, marital status and duration of work. On multiple regression analysis, the factors affecting innovation behavior of general employees were developmental culture( =.297, ${\beta}$ p<.01), group culture (${\beta}$=.184, p<.01) and job satisfaction(${\beta}$=.148, p<.05). And the factors affecting innovation behavior of managers were developmental culture(${\beta}$=.181, p<.01), rational culture(${\beta}$=.171, p<.01) and group culture(${\beta}$=.408, p<.01), In conclusion, the results of this study show that organizational culture and job satisfaction influence hospital nurses'innovation behavior.

This study examined the parenting beliefs and the achievement pressure of Korean mothers with five to seven year old children. The maternal parenting beliefs criterion (Ahn, 2001) and achievement pressure criterion (Hong, 2001) have been applied to 212 mothers living in Seoul or Kyonggi-Do area and analyzed. The results showed that the maternal parenting beliefs were influenced by the child's gender, while the maternal achievement pressure was not. And significant difference was seen only in between the educational background and the maternal parenting beliefs, and the employment status and interaction effects were not shown.

In hypoxic tissue conditions, pyruvate can not enter the Krebs cycle and lactic acid, produced from pyruvate, accumulates to induce lactic acidosis. Pyruvate, However, can also be converted to alanine by glutamate pyruvate transaminase, that could be enhanced by glutamate. Therefore, it would be a fundamental measure to treat the lactic acidosis in tissue hypoxic conditions when one can convert the accumulated lactic acid, through pyruvate, to alanine. To test the above hypothesis, we induced a lactic acidosis in cats and the effect of glutamate on recovery of acid base state and removal of the lactic acid from blood were assessed and the results were compared with those of bicarbonate administration, which is one of the most frequently used conventional measure for correction of the acid base state during lactic acidosis. The results were that glutamate and combined glutamate bicarbonate solutions not only restored the acid base status completely from the lactic acidosis in an hour or two, but also restored the blood level of lactate partially. We concluded that administration of glutamate solution to convert pyruvate into alanine is effective in preventing lactic acid accumulation and treating lactic acidosis.

Purpose : This study examined the effects of work environment and organizational culture on tertiary hospital nurses' turnover intention. Methods : A cross-sectional design was used, with a convenience sample of 371 hospital nurses from 16 units of three tertiary hospitals in South Korea. Data were collected through a self-report survey conducted during September and October 2016. Data were analyzed using the chi-square test, Fisher's exact test, independent t-test, and binary logistic regression analysis. Results : A total of 43.7% of the participants were identified as having turnover intention within 1 year. Factors related to turnover intention among hospital nurses were age, marital status, and total clinical career. Furthermore, a relationship-oriented organizational culture showed a negative association with turnover intention. Conclusion : These findings suggest it is important to provide appropriate motivational programs and incentives for nurses according to their clinical career to decrease turnover intention. Moreover, establishing a relationship-oriented organizational culture will also help to reduce the turnover intention of tertiary hospital nurses.
