Objectives: In South Korea (hereafter Korea), the number of adolescent offspring of immigrants has rapidly increased since the early 1990s, mainly due to international marriage. This research sought to examine the association between the experience of school violence and mental health outcomes, and the role of help-seeking behaviors in the association, among biethnic adolescents in Korea. Methods: We analyzed cross-sectional data of 3627 biethnic adolescents in Korea from the 2012 National Survey of Multicultural Families. Based on the victim's help-seeking behavior, adolescents who experienced school violence were classified into three groups: 'seeking help' group; 'feeling nothing' group; 'not seeking help' group. Multivariate logistic regression was applied to examine the associations between the experience of school violence and depressive symptoms for males and females separately. Results: In the gender-stratified analysis, school violence was associated with depressive symptoms in the 'not seeking help' (odds ratio [OR], 7.05; 95% confidence interval [CI], 3.76 to 13.23) and the 'seeking help' group (OR, 2.77; 95% CI, 1.73 to 4.44) among male adolescents after adjusting for potential confounders, including the nationality of the immigrant parent and Korean language fluency. Similar associations were observed in the female groups. However, in the 'feeling nothing' group, the association was only significant for males (OR, 8.34; 95% CI, 2.82 to 24.69), but not females (OR, 0.77; 95% CI, 0.18 to 3.28). Conclusions: This study suggests that experience of school violence is associated with depressive symptoms and that the role of victims' help-seeking behaviors in the association may differ by gender among biethnic adolescents in Korea.

This study was intended to provide basic information for nutrition education and meal planning by evaluating the nutritional status, food habits, and food preference of elementary school children with school lunch program and without school lunch program(lunch box). The subjects of this study consisted of 266 elementary school children aged from 10 to 12(136 male, 130 female) in Ulsan the area. The survey was conducted by questionnaires and data were analyzed by SPSS program. The average body weight was $38.4{\pm}6.9kg$ for boys and $36.8{\pm}7.4kg$ for girls and the average heights was $141.3{\pm}5.6cm$ for boys and $141.2{\pm}5.7cm$ for girls. These values were lower than that of the Korean reference. 56.0% of the subjects skip breakfast 1 to 2 times a week, 58.2% of the subjects had prejudice for special food, such as bean, anchovy, and pork. The food habit scores of the subjects was divided into poor(11.7%), fair(63.5%), and good(24.8%). The average score of girl's was significantly(p<150) higher than that of the boy's. Compare to 1/3 of RDA for children, the average intake of nutrients provided lower amounts of all nutrients. Therefore Calcium and vitamin A intakes were especially lower than the others. Therefore the importance of milk and green vegetables must be emphsized to them through nutrition education. Children preferred ssalbab to jabkogbab and liked beef-based soup, and baechu kimchi. There were significant differences in food habit scores with gender, parent's education, and exercise. The results of this study indicate that nutrition education and menu planning program should be applied to elementary school children who are served by the school lunch program.

Functional stay-green is a beneficial trait that may increase grain yield through the sustained photosynthetic competence during monocarpic senescence in cereal crops. The temporal changes of photosynthesis and related characteristics throughout the grain filling period of a stay-green japonica rice "SNU-SG1" was compared in growth chamber conditions with three high-yielding cultivars(HYVs) and their $F_1$ hybrids with SNU-SG1. SNU-SG1 exhibited a typical characteristic of functional stay-green in terms of chlorophyll degradation and photosynthetic competence during grain filling. According to the photosynthesis-light response curve measured at 10 and 35 d after heading for the flag leaf, SNU-SG1 exhibited higher initial light conversion efficiency and thus higher gross photosynthetic rate at light saturation compared to HYVs. Light saturation point was not different among genotypes, ranging from 1000 to 1500 ${\mu}mol$ photon $m^{-2}s^{-1}$. Net photosynthetic rate at light saturation($P_{max}$) of the upper four leaves in SNU-SG1 was much higher and sustained longer throughout grain-filling than HYVs and $F_1$ hybrids. The sustained high photosynthetic competence of SNU-SG1 during grain filling was ascribed to the longer maintenance of high mesophyll conductance that resulted from not only high chlorophyll content and its delayed degradation but also the slow degeneration of photosystem II(PS II) as judged by chlorophyll fluorescence($F_v/F_m$) of flag leaves. $F_1$ hybrids showed slow degeneration of photosystem II similar to the male parent SNU-SG1 while chlorophyll degradation pattern close to female parents, thus exhibiting a little higher $P_{max}$ than female parents. These results suggest that SNU-SG1 has a typical functional stay-green trait that can be utilized for increasing rice yield potential through the improved dry matter production during grain filling.

The bioequivalence of two cyclosporine A (CyA) 100 mg soft capsules (Chong Kun Dang's $Cipol-N^{(R)}$ as the test drug; Korea Novartis' Sandimmun $Neoral^{(R)}$ as the reference drug) was assessed in healthy male Korean volunteers after oral administration of 200 mg CyA according to a randomized crossover design. The whole blood samples were analyzed for the determination of parent CyA in the blood by using a validated HPLC/diode array detector method. The mean $AUC_t$ values for reference and test products were $4095.3{\pm}1397.2$ and $3958.3{\pm}1138.2\;ng{\cdot}hr/mL$, respectively. The mean $C_{max}$ values were $1135.9{\pm}293.2\;ng/mL$ for the reference product, and $985.0{\pm}207.9\;ng/mL$ for the test product. $T_{max}$ was $1.6{\pm}0.4\;hr$ for the reference and $1.8{\pm}0.5\;hr$ for the test product. The differences of $AUC_t$, $C_{max}$ and $T_{max}$ were -3.35, -13.28 and +10.63%, respectively. The point estimates and 90% confidence intervals for $AUC_t$ and $C_{max}$ were 0.981 (0.9171 to 1.0514) and 0.876 (0.8229 to 0.9336), respectively. Based on the pharmacokinetic and statistical data, we conclude that these two products are bioequivalent and can be considered interchangeable in the medical practice.

Objective : Microscopic indocyanine green (ICG) angiography is useful for identifying the completeness of aneurysm clipping and the preservation of parent arteries and small perforators. Neuroendoscopy is helpful for visualizing structures beyond the straight line of the microscopic view. We evaluated our prototype of endoscopic ICG fluorescence angiography in swine, which we developed in order to combine the merits of microscopic ICG angiography and endoscopy. Methods : Our endoscopic ICG system consists of a camera, a light source, a display and software. This system can simultaneously display real-time visible and near infrared fluorescence imaging on the same monitor. A commercially available endoscope was used, which was 4 mm in diameter and had an angle of $30^{\circ}$. A male crossbred swine was used. Results : Under general anesthesia, a small craniotomy was performed and the brain surface of the swine was exposed. ICG was injected via the ear vein with a bolus dose of 0.3 mg/kg. Visible and ICG fluorescence images of cortical vessels were simultaneously observed on the display monitor at high resolution. The real-time merging of the visible and fluorescent images corresponded well. Conclusion : Simultaneous visible color and ICG fluorescent imaging of the cortical vessels in the swine brain was satisfactory. Technical improvement and clinical implication are expected.

This study was designed to explore whether the temperament of a child influences the physical growth. The Korean version of the Parent Questionnaire for Children developed by Thomas, Chess and Korn was applied to 395 Korean children whose ages ranged from 3 years to 7 years. Simultaneously the height and the weight were measured for each child and converted into percentile scale according to the Growth Curve and the Weight Percentile Table for the Height of Korean children. Statistical analysis was performed among 9 temperamental categories, height and weight percentiles for the age and weight percentiles for the height using the first-order partial correlation analysis, controlling for the familial mean income per month. Results showed that the more temperamentally difficult a child is, the lower weight he has when compared with the children of the same age or the same height. Although there were some differences, the tendency of the above findings was maintained both in male and female children. These results show that the temperament may influence the physical growth as well as the psychological development.

This study is to investigate the factors which affect self- esteem of the aged parents. In this study questionaires were used to measure solidarity between aged parents and adults children, self- esteem of aged parents. Subjects were 234 male and 235 female parents who were aged over 60. The data were analyzed by using frequency, percentage, mean, standard deviation, ANOVA, and stepwise regression analysis. The results are as follows : 1) The solidarity between the aged parents and their adult children is average 65.5(Conversion value by 100 : 51.9) and shows the average level. The relations between solidarity and background variables are variables affected by education, pocket money, health, social activity and religion. 2) The degree of self- esteem in the aged parents is presented to average 26.1(Conversion value by 100 : 56.5) and shows the average level and it according to the background variables has a significant difference depending on education, pocket money, family living together, health, social activity, religion and the number of children. 3) To investigate the degree of self- esteem according to the degree of solidarity, the sub-areas of solidarity are subdivided into five groups. higher solodarity the group has, higher self- esteem it has. 4) The degree of effects of the variables which affect self- esteem in the aged parents is in such order as affectional solidarity($\beta$＝0.32), helping($\beta$＝0.14), education($\beta$＝0.10), solidarity by contact($\beta$＝0.09) and solidarity by argument($\beta$＝0.09) and $R^2$ of such variables are 30%.

Background: Research evidence suggests a debilitating impact of the diagnosis of cancer on the quality of life of the afflicted individuals, their spouses and their families. However, relatively few studies have been carried out on the impact on the QOL of adolescents living with parents diagnosed with cancer. This paper presents a sub-analysis on the impact of parental cancer (colorectal, breast and lung) on adolescents. Materials and Methods: This is a cross-sectional study on adolescents aged 13-18 years old. Upon ethical clearance obtained from UMMC Medical Ethics Committee, patients with colorectal, breast or lung cancer and their adolescent children were recruited from the Clinical Oncology Unit of University of Malaya Medical Centre. Respondents who gave consent completed a demographic questionnaire and the Pediatric Quality of Life Inventory, via the post, email, home visit or meetings at the clinics. Results: 95 adolescents from 50 families responded, giving a response rate of 88 percent. The adolescent's mean age was 16 years (ranging between 13-18 years). Adolescents with parental cancer had the lowest mean score in emotional functioning (p<0.05). Male adolescents had significantly higher quality of life overall and in physical functioning compared to female adolescents. Adolescents with a father with cancer had better school functioning compared to adolescents whose mothers had cancer. Families with household income of RM 5000 and above have significantly better quality of life compared to families with lower household income. Conclusions: Adolescent sons and daughters of parents with a cancer diagnosis show lowered QOL, particularly with reference to emotional functioning and school performance. Addressing the needs of this young group has been slow and warrants special attention. Revisiting the risk and resilience factors of adolescents might also inform tailored programs to address the needs of this neglected adolescent population.
