This study was performed to determine health-related dietary and lifestyle of characteristic factors associated with sodium hyperingestion of korean adults by sexual difference. Study subjects were 30~69years (n=1,622) adults who participated in the 2010 Korean National Health and Nutrition Examination Survey (KNHANES V-1). Subjects were divided into the hyperingestion group (HG, n=1,494) and normal ingestion group (NG, n=128) by 'WHO growth standard sodium intakes(2,000mg/day)' and the relationships between Comparison of demographics and physical measurement, eating behaviors and health-related factors were analyzed. By logistic regression method, risk factors for sodium hyperingestion group revealed in this study were gender(female), number of family', 'breakfast', 'lunch', 'dinner', 'nutrition labeling use'. and In case of male, risk factors for sodium hyperingestion group were 'lunch', 'dinner', 'self-rated body image' of eating behaviors. In case of female, Which were number of family' of demographics, 'breakfast', 'lunch', 'dinner' of eating behaviors. In these results, according to different sexual aspect of sodium hyperingestion, we suggest that nutrition label use and proper nutrition intake criteria among sexual, recognition promotion campaign along with education program for repressed sodium hyperingestion related to hypertension prevention of korean adults should include eating habits improvement and demographics lifestyle modification.

Education about invention in elementary schools has thus far be conducted mostly through special activities and talented activities rather than through normal curricula. However, with the implementation of the 2007 amended curricula, invention education was reflected as a normal subject unit in the practical subject (technology and home economics) curricula, thereby laying groundwork for invention education being able to be provided through normal subject classes. Thus, at the time when invention education has been reflected as a normal subject unit, it is meaningful to research the effects of elementary school students' experience in invention education on their invention attitudes. This study sought to research the effects of elementary school students' experience or non-experience in invention education on their invention attitudes, targeting those in regional talent private schools who did not take invention talent classes, those who received invention education, and those who did not receive invention education at all. The conclusion of this study is outlined as follows. First, students' experience in invention education proved to be positive in boosting their invention attitude, and continued invention education experience like with students in regional talent invention schools significantly boosted their invention attitudes. Second, considering that students' actual experience in invention education had positive effects on their invention attitudes, the reflection of invention education in the amended curricula was found to be very desirable in improving elementary students' attitudes about invention. Third, according to gender, male students' invention attitude level was found to be higher than that of female students, suggesting that male students more worked on computers, electronic (smart) devices and machines in daily life, leading them to further develop invention attitudes.

The purpose of this study was to provide educational data on teaching clothing culture by examining the effects of clothing lifestyle on attitudes toward teachers' clothing for 270 secondary school pre-service teachers. For data analysis, factor analysis, Cronbach's α reliability coefficients, t-tests, one-way analysis of variance, Duncan's multiple comparison verification, and multiple regression analysis were performed using SPSS 24.0 program. As a result of the study, first, the clothing lifestyle of secondary school pre-service teachers was classified as fashion trend orientation, clothing importance orientation, attractive appearance orientation, and economic orientation factors. In addition, the attitude toward teacher's clothes was classified into activity, fashionability, and modesty factors. Second, there was a statistically significant difference in the attitudes toward clothing lifestyle and teacher clothing of secondary school pre-service teachers according to gender and year in college, which are demographic variables. Third, it was found that the clothing lifestyle of secondary school pre-service teachers, who are Generation Z, had an effect on the attitude toward teacher clothes. In conclusion, this study proposes that school administrators and teachers should depart from the former stereotypes about teacher clothes and to encourage a culture in which teachers can dress and perform their role of teaching according to individual's changing lifestyles.

For knowing the effects of aging on conversational skills in daily communication, this paper studied for the conversational turn-taking skills, working memory and naming ability on healthy elderly adults over 65 ages. 85 elderly adults participated in this study, which divided into four groups by ages. Speech samples were collected in natural conversation. Memorization of numbers, mental calculation, repetition of words were administered for working memory test. K-BNT was used for the naming ability. One-way ANOVA analysis was used for the comparison of conversational turn-taking skills among four groups. We analyzed the correlation between conversational skills, working memory and naming ability. The results were as follows: first, there were a significant difference in conversational turn-taking skills by age, but not by gender. There was a significant difference in 'Turn-Taking Frequency' and 'Total Utterance Frequency' among four groups. The same results were shown in the scores of females within three groups(exclude groups over 85D)(p<.01). Second, there was a significant correlation between 'rates of maintenance' and 'naming ability'. In addition, it was found that the naming test predicted 'rates of maintenance' skills. The results of this study suggest that word-retrieval ability will be helpful to enhance functional communication skills in aging old adults.

Purpose: The purpose of this study was to evaluate the convergence accommodation to convergence (CA/C) ratio and to investigate relationships among age, accommodative amplitude and PD (interpupillary distance) of adults in their early twenties with normal binocular vision. Methods: 44 subjects (mean age, $21.75{\pm}1.16$ years) with healthy eyes were examined. The CA/C ratios were measured by using the difference of Gaussian (DOG) target with retinoscopy. Results: The mean CA/C ratio was $0.052{\pm}0.017$ D/$\Delta$. A moderate negative correction was present between CA/C ratio and age (r = -0.50, p = 0.0005), and a highly positive correction was found between CA/C ratio and accommodative amplitude (r = 0.79, p<0.0001). There was no relation between PD and CA/C ratio. Conclusions: The CA/C ratio presented was mean value for adults in their early twenties with healthy eye between 19 and 25 years of age. There was a high correlation between accommodative amplitude and CA/C ratio. Therefore, the CA/C ratio will be useful basic information for comparison in age, gender and binocular anomalies with similar data from other countries.

Purpose: This study was performed to provide indicator of expected aniseikonia by correcting refractive error and to investigate influential factors on aniseikonia. Methods: 20 college students (14 males, 6 females, a mean age of $22.50{\pm}2.72$ years) were selected as subjects whose refractive error with spherical equivalent were within ${\pm}0.50$ D, corrected visual acuity were more than 1.0, and aniseikonia values by AWAYA were less than 1%. After correcting refractive error with spectacles in anisometropia induced by wearing contact lens on their dominant eye or non-dominant eye, practical measured values of aniseikonia were compared with theoretical expected values of it by the formula of spectacle magnification. Results: Practical measured values were higher than theoretical expected values in induced aniseikonia over the whole range of diopter of wearing contact lens. And there was higher measured value of aniseikonia in case of higher diopter of wearing contact lens to induce anisometropia and correcting refractive error with spectacles of (+) diopter after wearing contact lens of (-) diopter to induced anisometropia in dominant eye of women. Conclusions: It is considered that dominant eye plays more important role for visual function in induced aniseikonia and factors such as the induced eye of aniseikonia, the diopter of wearing contact lens, and gender have influenced on aniseikonia.

This study was to develop the assessment of medical service outcome using administration data through compared with hospital standardized mortality ratios(HSMR) in various hospitals. This study analyzed 63,664 cases of Hospital Discharge Injury Data of 2007 and 2008, provided by Korea Centers for Disease Control and Prevention. We used data mining technique and compared decision tree and logistic regression for developing risk-adjustment model of in-hospital mortality. Our Analysis shows that gender, length of stay, Elixhauser comorbidity index, hospitalization path, and primary diagnosis are main variables which influence mortality ratio. By comparing hospital standardized mortality ratios(HSMR) with standardized variables, we found concrete differences (55.6-201.6) of hospital standardized mortality ratios(HSMR) among hospitals. This proves that there are quality-gaps of medical service among hospitals. This study outcome should be utilized more to achieve the improvement of the quality of medical service.

This study is targeted to understand the giving of time and money among citizens in Seoul. It explores predictors of different combinations of giving behaviors: only volunteering, only donating, doing both, and neither. In exploring predictors, it also considers the effects of intensity in giving with differential measurement of general participation and regular participation. For the analysis, this study utilizes Seoul Welfare Panel Survey Data in 2008 and 2010 and employes a multi-nominal logistic regression model with selection of citizens' demographic factors, pro-social attitude factors, and psycho-social factors on these four type of giving behaviors. The findings show that previous giving experiences(+) and religious activities(+) have statistically significant effects on both selective and combined giving behavior. Gender(woman), income(+), education(+) have statistically significant effects on giving behaviors(only donating and doing both) related with donation. In the case of employment state, unemployment is significantly related to volunteering while employment is significantly related to donating. Finally, happiness(+) has significantly positive effect on intensive giving such as regular giving rather than general giving. This analysis has made a start in a new area of inquiry attempting to explain different giving behaviors with broadening and promoting understanding on giving behaviors. Moreover, it raises several implications for future research and strategic practice for resource mobilization of NPOs.

Purpose: This study was found the risk factors of cataract by gender in elder and older Korean adults. Methods: We investigated the data for 5,024 (men 2,163 people, women 2,861 people) people, aged 40-95 years, from the Korean National Health and Nutrition Examination Survey. We divided into two groups (group 1: 40-64 years, group 2: 65-94 years). We divided into two groups (group 1: 40-64 years, group 2: 65-94 years). Cataract was decided in case of at least one eye with lens opacity. We presented significant odds ratio (OR) increase of cataract according to the obesity and socioeconomic information including house income and education level after adjusting for diabetes, hypertension, high triglyceride, outside active, smoking and drinking habits in two groups with distinction of sex. Results: House income (or education) was strongly related to the prevalence of agerelated cataract in all groups. In models adjusting for all other related factors, cataract patients with lower income and education had a higher prevalence of cataract (group1: OR, 1.84[1.17-2.91], OR, 3.00[1.90-4.74], group 2: OR, 3.47[2.53-4.74], OR, 7.44[5.41-10.23] for men. In comparison, for women, cataract patients with lower income, lower education and obesity had a higher prevalence of cataract (group1: OR, 1.72[1.14-2.60], OR, 4.48[2.72-7.38], OR, 1.40[1.10-1.82], group 2: OR, 2.32[1.70-3.16], OR, 29.99[20.31-44.28], OR, 1.27[1.04-1.54]). Conclusions: Factors of low socioeconomic status were associated with age-related cataract in Korean. Obesity-cataract association was stronger in women.
