The purpose of this study is to examine which factors determine self-rated health(SRH) among Korean elderly focusing on gender differences. To achieve this purpose, it uses the Hallym Longitudinal Study of Aging, wave 4 in 2009. Participants aged 65 and over from wave 4 were selected(N=986, male 407, female 579). From wave 4, all variables were selected except for respondents' education which was from wave1. In analyses, $x^2$ or t-test were conducted to examine whether independent variables significantly differ by SRH. Then, since a dependent variable consisted of two categories-being healthy or not being healthy, logistic regressions were run. What makes gender differences in the link of independent variables to SRH were 75-84 age group, education, and IADLs. For females, 75-84 age group rated their health as worse compared to 65-74 age group, but this age group did not have significant effect on SRH for males. Females graduating from junior high school were more likely to higher rate their health compared to their counterparts. However, education was not significant for males. Instrumental activities of daily living(IADLs) is one of variables affecting SRH by making gender differences. Female having problems with IADLs were more likely to be significantly negatively rate their health compared to males. Through focusing on age, education, IADLs making gender difference in evaluating health, governments needs to support males and females differently.

This study investigated how people who became blind midway through life used music and how these uses differed according to individual factors. Sixty-one late-blind adults aged 40 to 60 years attending six welfare centers for the blind in Seoul and Gyeonggi region participated in this research. Participants were asked to complete a 25-question survey in Braille on music utilization and preference, as well as the purpose of music utilization. The response rate was 87.1%. The results were as follows. First, with regard to listening preference, they reported preferring to listen to upbeat popular music on the radio when resting at home. They liked to sing along to lyrics reminiscent of personal memories. String instruments were preferred when playing an instrument. With regard to the reason for using music, inducing mood change was found to be the biggest reason, followed by seeking enjoyment, comfort, sense of achievement, and sense of belonging. Third, for people with adventitious visual impairments, individual factors, such as gender, level of disability, and period without eyesight, did not reveal any significant differences. Last, participants were found to obtain a higher sense of belonging through music compared to those having low vision. Regarding time without eyesight, it appeared that the shorter the period, the higher the sense of belonging participants had from utilizing music, and vice versa. This study provides fundamental information for organizing an effective music program that can meet the needs and demands of people with adventitious visual impairments.

The purpose of this study was to identify the validity, reliability, and discriminative index of the Korean version of Modified Barthel Index (K-MBI). For this, two hundreds twenty-thee stroke patients participated. Activities of daily living were measured through using K-MBI. Factor analysis was performed for identifying the construct validity and internal consistent and discriminative index were calculated. The result of factor analysis was that the 10 items of K-MBI have communality above .50, and was constructed one factor. Explained variance was 72.184%. The order of factor loading value was toileting, personal hygiene, transfer from bed to chair and back, ambulation/wheelchair, dressing, feeding, bowel control, bathing, bladder control, and stair climbing. Cronbach ${\alpha}$ of K-MBI was .994. The range of discriminative index was .783~.909, and was acceptable. One factor of K-MBI was identified through factor analysis, and reliability and discriminative index was also identified. Various psychometric properties of K-MBI should be investigated in further studies for valid assessment of activities of daily living in stroke patients.

The objective of this study was to determine the effect of replacing corn with soy hulls on nutrient digestibility of growing pigs. Three experimental diets were tested using a 3 × 3 Latin square design using three barrows per group (Landrace × Yorkshire × Duroc, average initial body weight of 36.9 ± 4.0 kg) in individual metabolic cages. The dietary treatments were the control (CON) basal diet (corn-soybean meal based diet), whereas in the test diets, soy hulls were included at 5% (H1), 10% (H2), gradually replacing corn. The daily feed allowance was adjusted to 2.7 times the maintenance requirement for digestible energy (DE) (2.7 × 110 kcal of DE/kg BW^0.75). Intake of crude fiber (CF) was different among treatments (p < 0.05). Pigs fed with H2 diet excreted higher concentrations of dry matter (DM), and CF than pigs fed with H1 diet and basal diet (p < 0.05). Pigs fed with H1 and H2 diets excreted higher concentrations of crude protein (CP) than pigs fed with CON diet (p < 0.05). The apparent total tract digestibility (ATTD) of CF from H1 and H2 diets were higher than CON diet (p < 0.05). Pigs fed with H2 diets were significantly lower (p < 0.05) the ATTD of CP than the pigs fed with CON and H1 diets. The current data suggest that 10% inclusion soy hulls can slightly decrease CP digestibility. However, soy hulls considerably increased CF digestibility.It is concluded that 5% soy hulls may be a usable alternative to corn in growing pig diets.

This study takes the position that present after-school classes affect the development of children's sociality and self-esteem, and aims at comparing, analyzing and grasping the differences in sociality and self-esteem of the children who attend after-school classes and those of the children who don't. First, when the differences of sociality were analyzed between the children going to after-school classes and those who weren't, it was revealed that those who attended after-school classes had rather lower level of sociality than those who didn't, but there were no statistically meaningful differences. Second, when the differences of self-esteem in regard to whether children took after-school classes or not were examined, those who were taking after-school classes were analyzed to have lower self-esteem than those who weren't. The study results showed that the children who went to after-school classes had lower sociality and self-esteem compared to those who didn't. Taking this fact into consideration, different ways should be found to improve their sociality and self-esteem. In addition, programs need to be developed and introduced so that after-school classes can not only fulfill their original purposes of protecting and guiding children, but also continuously elevate and maintain children's sociality and self-esteem.

This study was conducted to identify the utilization of public health centers, as well as the individual characteristics and regional characteristics that affect their utilization based on data from the 2016 Community Health Survey, National Statistical Portal, and National Institute of Environmental Research. Independent samples t-tests, variance analysis, and multiple logistic regression analysis were used for analysis. Hierarchical multiple regression was used to analyze individual and regional characteristics. The results of hierarchical multiple regressions revealed that aged regions, women, older age individuals, respondents with lower education level and income level, walking practitioners, nutrition label readers, individuals experiencing depression, those who have received health checkups, those who are not covered by essential care, those who have spouses, and basic livelihood beneficiaries have increased use of public health centers. However, the use of public health centers decreased in stressors, and regions in which the population per 1,000, number of health care workers, health and welfare budget, fiscal independence, and unemployment rate were above the national average. As above, the central government and local governments need to analyze not only individual characteristics such as health behavior and psychological factors, but also regional characteristics, when establishing local health care policy.

Pyrrosia lingua which belongs to Polypodiaceae has been used as a traditional medicine for the treatment of urinary system inflammation, urination disorder, and bronchitis. However, there are not enough phytochemical and pharmacological studies of P. lingua up to now. Here in this study, the protective effect of MeOH extract of whole plant of Pyrrosia lingua (MPL) against 2% glucose-induced toxicity was investigated using Caenorhabditis elegans (C. elegans) model system. We found that MPL significantly extended the lifespan of wild-type nematode under normal culture condition. MPL also effectively recovered the decreased lifespan caused by 2% glucose-toxicity. In addition, MPL efficiently attenuated the increased glucose concentration inside of nematode. Further studies evaluating diabetes-related factors revealed that MPL reduced both intracellular ROS and lipid accumulation which were up-regulated under 2% glucose supplement condition. Our data also showed that MPL improved the 2% glucose-induced shortened body movement of nematode. Lastly, we carried out genetic studies using several single gene knockout mutants to establish the possible target of MPL. Our results demonstrated that genes such as daf-2 and daf-16 were responsible for the protective activity of MPL against 2% glucose-induced toxicity. These results indicate that MPL exerts protective action against 2% glucose via regulation of insulin/IGF-1 sinaling pathway and FOXO activation.

This study investigated how the big five personality traits among clinical laboratory science students affect their levels of academic satisfaction and verified the mediating effect of career preparation in the context of these personality traits influencing academic satisfaction. A total of 300 college students attending a 3-year college in Daegu were surveyed, and 260 were analyzed. SPSS 22.0 was used for statistical analysis while Baron and Kenny (1986)'s three step method was carried out for basic analysis, correlation analysis, and verification of the mediating effect of the collected data. Results of this study are as follows. Firstly, the correlation analysis between variables shows that extroversion, openness, agreeableness, and conscientiousness among the big five personality traits had significant positive relationships with academic satisfaction and career preparation while neuroticism showed a significant negative relation with academic satisfaction and no significant relation with career preparation. Secondly, the mediating effect verification found that extroversion, openness, agreeableness, and conscientiousness, but not neuroticism, had significant mediating effects; extroversion especially was confirmed to have a complete mediating effect. Thus, methods are needed to improve academic satisfaction and career preparation in college.
