Background: Bulgarian split squat (BSS) is beneficial to improve dynamic balance ability and muscle activity of lower extremities, however its effects have not been fully investigated. Therefore, this study aimed to compare changes in dynamic balance ability and muscle properties according to various modifications of BSS exercises. Methods: Thirty healthy male volunteers participated in this study, and they were randomly divided into three different groups. The subjects performed the BSS exercise either on a stable surface with the eyes opened (n=10) or eyes closed (n=10), and on an unstable support plane with eyes opened (n=10) conditions, respectively. Dynamic balance ability was measured via Biodex balance system under the eyes-opened and closed conditions. Additionally, muscle properties of the rectus femoris (RF), vastus medialis (VM) and vastus lateralis (VL) were evaluated. Results: Dynamic balance ability did not show the significant differences among the groups that performed the BSS exercises. However, in the Unstable group, there were significant differences in the overall stability index and anterior posterior stability index under the eyes-closed condition between pre-exercise and post-exercise. In comparison of muscle properties according to the groups, RF muscle showed a significant difference in amount of change of elasticity (p=.038). Additionally, there were significant changes in post measurements of VM muscle tone (p=.016), stiffness (p=.012) and elasticity (p=.002). VL muscle, however had no significant differences in muscle properties. Conclusion: These results indicate that BSS exercises could induce the alteration of RF and VM muscle properties, in particular VM muscle which is susceptible to weakness. Thus, BSS could be applied in various ways as an effective rehabilitation exercise.

Objectives: The purpose of this study was to provide fundamental resources for preventing adolescents' bullying behavior. For this aim we analyzed parents' rearing attitudes and adolescents' personality characteristics effecting on bullying experiences. Methods: We carried out a questionnaire survey at middle and high school located in Anyang, Gwacheon, Gunpo from July 8 to 22, 2013. Data were collected from 756 students. By using SPSS 20.0, data were analyzed by descriptive statistics, correlation analysis, and hierarchical regression analysis Results: There was a close relationship among parents' rearing attitudes, adolescents' personality characteristics, and bullying experiences. Parents' affectionate rearing attitudes reduced adolescents' bullying experiences, on the other hand parents' hostile and rejective rearing attitudes increased. The adolescents with high responsibility had low bullying experiences, otherwise adolescents with high activity had high bullying experiences. Conclusions: In order to reduce bullying experiences parents' rearing attitudes should be changed and education programs that could encourage a sense of responsibility should be introduced.

This study aimed to analyze and compare results from psychological relaxations by using profile of mood state (POMS) and Malondialdehyde (MDA) level as a scale of oxidative damage before and after walking in the forest and on the street. 29 participations (15 men and 14 women) walked in the forest and on the street for 30 minutes of each for two days. The participations filled a questionnaire for POMS and conducted an heart rate variability test, oxidative damage test (MDA as biological marker through a urine test) before and after walking. To compare the psychological states after walking in the two difference places, walking in the forest showed statistically more meaningful results in the section of tension, depression, anger, fatigue, confuse and total mood disturbance (p<0.01) than walking on the street. According to the MDA results, a concentration of MDA showed significant increase after walking on the street (p=0.014). On the contrary to this, a concentration of MDA tended to decrease after walking in the forest (p=0.076). The study showed that the psychological states were more stable and oxidative damages were more decreasing after walking in the forest than walking on the street. In the conclusion, MDA would be biological indicator for assessing the effect of alleviation on the oxidative stress after walking in the forest.

Park Tae-Joon, a pioneer in the Korean steel industry, has greatly influenced the advancement of science and technology as well as the development of the nation's economy. He believed that POSCO, which was a government-owned company, should not only focus on making profits, but also operate for higher state-level purposes. This belief became the basis for founding a general laboratory and a research university, as well as building big science and technology R&D facilities. Park Tae-Joon's efforts to establish a research university and his dedication to the advancement of science education stemmed from his devotion to public welfare. Just like he believed that the steel industry, which is the basis for all other industries, should be promoted at the state-level, he believed that university and basic science should also be promoted at the state-level. Thanks to his philosophy, the Pohang University of Science and Technology has risen beyond just a polytechnic school to become a research university that makes revolutionary science and technology advancements for the nation. The fact that Park Tae-Joon used profits from business to build the university and national research facilities such as the Pohang Light Source also shows that he nurtured pure science with the welfare of the whole nation in mind.

This study aims to find the extent to which the elderly intends to live in their community and significant factors related to their intention and to provide basic but important empirical data in approaching to various community resources for community care service for the elderly. This study analyzed the raw data titled social welfare needs of residents of Busan Metropolitan City surveyed in 2005. Within the data, 1,673 households were selected in which at least one senior citizen aged 65 and over lived together. Questionnaires from in each household were analyzed. Research findings indicate that 80% of the respondents intend to live in their home rather than in residential institutions and that the elderly without adult children(55.2%) have less intention for living in their home than the elderly without their spouse(76.4%). Their intention-related factors were the presence of adult children, recognition on community resources for the elderly and perceived number of chronic diseases, when they were presumed to be healthy. When they were presumably weak or ill, socio-economic factors such as home ownership and welfare recipience were found to be more influential factors than family-related variables. The elderly who intended to live in home rather than to live in a residential institution were less likely to use social services in community than expected. Policy and practice implications were suggested on the basis of the findings.
