Purpose: The purpose of this study was to analyze the image of nurses portrayed on Korean TV dramas. Methods: Among the medical dramas aired on TV from 2000 to 2013, sixteen different Korean TV dramas were selected. For analyzing the dramas, 'the checklist for monitoring media images of nurses and nursing' was used after obtaining the permission from the original author. Two evaluators evaluated each drama and synchronized the final scores after comparing individual scores. Results: The roles of nurses were found to be such a supportive role (93.8%), and a professional role (75.0%). The nurses images portrayed on the selected TV drama included being kind, accountable, having humanism (81.2%), and professional insights (56.2%), whereas nurses's administrative role such as a manager were not represented. A half of scenes that nurses showed up, nurses were asking asking for help to doctors or other hospital administrators. Conclusion: Since TV dramas on air in Korea still underrepresented the roles of the professional nurses, providing the media with advice to improve the images of nurses is necessary in future. Concrete and sustainable strategies for improving nurses image are required.

Objectives : The purpose of this study was to investigate how the play habits, temperament, and environmental factors might affect childhood obesity. Methods : Two hundred sixty children, aged 4 through 6 years living in Seoul & Cheonan were surveyed by a questionnaire about the children's play habit and the parent's related factors such as weight, height, education, income. In addition the Korean version of the Parent Temperament Questionnaire for Children and the Korean version of the Family Environment Scale were also administered to parents of those children. The height and weight of those children were measured and the percentage of body fat was measured by Bioelectrical Impedance Fatness Analyzer. Result : 1) Among 260 children, 25 children were considered to be obese on the basis of both obesity index and percentage of body fat. 2) Parents of obese children showed a significantly higher educational level(p<0.05) and mothers of obese children had significantly more jobs(p<0.05) and showed higher body mass index(p<0.05) than those of nonobese children. 3) By observing play habits of children, obese children spent significantly longer time in watching TV and video(p<0.05), while nonobese children showed a trend to play outside(p<0.1). 4) On the Korean version of the Parent Temperament Questionnaire for Children, obese children showed significantly less activity than nonobese ones(p <0.05). 5) Family of obese children had significantly higher point on subscale of Achievement orientation, Intellectual-cultural orientation and Moral-religious emphasis of the Korean version of the Family Environment Scale(p<0.05). 6) Percentage of body fat of obese children was correlated with children's watching TV time, activity level, scores of Achievement orientation, Intellectual-cultural orientation of the Korean version of the Family Environment Scale and the both parent's education levels(p<0.05). Conclusion : Obese children showed hypoactivity and more watching TV time. And obese children's both parent had higher educational level and their mother had higher Body Mass Index and more jobs. Family of obese children had higher point on items of Achievement orientation, Intellectual-cultural orientation and Moral-religious emphasis. Family environmental factors influence on children's obesity through interaction of genetic and behavioral-psychological factors concomittently.

The detection technique both the polarization and the mobile charge density at the same time in ferroelectric films on Si using TVS method have been proposed. This method yields a polarizable and an ionic displacement current peaks whose areas are proportional to the total polarization reversal charge and the total moble ionic space charge, respectively. The calculated polarization and the mobile charge density were 0.42 [$\mu$C/$\textrm{cm}^2$] and 5.5$\times$10$^{11}$ (ions/$\textrm{cm}^2$) in the SBT film of MFIS structure measured at 25$0^{\circ}C$, and 1.4 [$\mu$C/$\textrm{cm}^2$] in the LiNbO$_3$ film of MFS structure measured at 30$0^{\circ}C$, respectively.

This study was carried out with 2,195 boy and girl middle school students in Inchon to examine environmental elements which may change vision and cause shortsightedness, and also to find out common knowledge of eye health. Its results are as follows. 1) As school year goes up, the normal eye sighted diminish but the visually handicapped regardless of left and right eyes increase. 2) Among weak sighted students below 0.9, boys are 42.2% and girls are 55.3%, the latter are larger by 13.1 %. Vision weakens rapidly especially for third year girl students. 3) Environmental, individual, everyday life elements which cause shortsightedness are studied, (1) environmental elements; illumination in watching TV and studying (2) individual elements; distance from TV and books, posture in studying (3) everyday life elements; hour of watching TV, hour of using game tools average, hour of studying 4) Knowledge of eye health is generally poor without regard to sex and wearing glasses. So adolescent students are in advance educated proper eye care to prevent shortsighted elements.

Purpose: Platycodon grandiflorum (a domestic diploid variety, DV-PG) has been used as a food and component of various traditional oriental medicines. Although DV-PG is known to have an anti-allergic effect, little is known about the beneficial health effects of the tetraploid 'Etteum' variety in the Platycodon grandiflorum (TV-PG), which is a recently developed variety. In this study, we investigated the effect of TV-PG on the rat basophilic leukemia mast cell (RBL-2H3)-mediated allergic response. Methods: To examine the effects of TV-PG on the allergic response, RBL-2H3 cells were sensitized with dinitropheny (DNP)-immunoglobin E, treated with various concentrations of TV-PG, and challenged with DNP-human serum albumin. We estimated cell granulation by measuring the release of ${\beta}$-hexosaminidase and production of inflammatory mediators by ELISA. Results: TV-PG had no effect on the proliferation or cytotoxicity of RBL-2H3 cells within the concentration range of 0 to $200{\mu}g/mL$. TV-PG inhibited degranulation of RBL-2H3 cells by antigen stimulation in a dose-dependent manner. TV-PG also suppressed the production of inflammatory cytokines and mediators such as interleukin-4, tumor necrosis $factor-{\alpha}$, prostagladin E2, and leukotriene B4 in RBL-2H3 cells by antigen stimulation. Conclusion: These results indicate that TV-PG exhibits anti-allergic activity via inhibition of degranulation as well as suppression of inflammatory mediators and cytokine release. These findings suggest that TV-PG may have potential as a preventive and therapeutic agent for the treatment of various allergic diseases.

Anaerobic Filters (AF) packed with porous ceramic floating media were operated at different operational conditions to identify the feasibility of the renewable bioenergy, methane production from swine wastewater and to verify the suitability of effluent from anaerobic filters for the subsequent biological nitrogen and phosphorus removal. Stepwise increase in organic loading rates (OLRs) or decrease in hydraulic retention times (HRTs) with influent TCOD concentration of 14,000 mg/L were utilized at mesophilic temperature. The maximum methane productivity of 1.74 volume of $CH_4$ per volume of reactor per day (v/v-d) was achieved at an hydraulic retention time (HRT) of 0.5 day (OLR 28 g TVS/L-d). Based on the biogas production, the highest total volatile solids (TVS) removal efficiency of 63% was obtained at an HRT of 3 days (OLR 4.67 g TVS/L-d), however based on the result from the effluent total chemical oxygen demand (TCOD) analysis, the highest TCOD removal efficiency of 75% was achieved. The effluent alkalinity concentration over the range of 2,050~2,980 mg/L as $CaCO_3$ at all operational conditions, could compensate the alkalinity destruction caused by nitrification. The effluent from the anaerobic filter operated under the HRT of 2 days showed the COD/TKN ratio of 15~35 and COD/TP ratio of 38~56. Therefore effluent C/N/P ratio is able to satisfy the optimum COD/TKN ratio of greater than 8.0 and COD/TP ratio of 33 for the subsequent biological nutrient removal.

The purpose of this study was to apply a scientific and systematic method for assessing fashion goods' TV ads effects by EEG and questionnaires as determined by the type of ads appeal. Ads stimulants used in the survey were limited to underwear and sportswear that were advertised during $2000{\sim}2002$ on TV: 4 information-transferring and 4 emotion-evoking ads were used. Subjects were thirty healthy male and female college students. EEG was extracted from six lobes and the recorded EEG was analyzed by the range of frequency of ${\theta},\;{\alpha}\;and\;{\beta}$ waves. Data were analyzed by SPSS 11.0 with reliability test, $x^2$-analysis, t-test and frequency analysis. The emotion-evoking ads showed higher scores in memory, recall and attitude towards the ads. The responses of ${\theta}\;and\;{\alpha}$ wave were active throughout the ads but the response of ${\beta}$ wave was not. The results by the survey and the EEG test showed high similarities, indicating the EEG tests could be used as the supplementary tool for measuring ads effects.
