This study estimated the causal relationship among leisure identity salience (LIS), leisure constraints negotiation (LCN), and intentions to participate in leisure activity (IPLA). For this, we estimated structural equation models controlled by leisure constraints, and we used data collected from 296 college students residing in Seoul and Kyoung-gi providence. The following was obtained. First, for both groups with high and low levels of leisure constraints, LIS positively caused LCN, and this became more evident for the group with high level of leisure constraint. Second, for the group with low level of leisure constraints, LIS positively and directly caused IPLA, whereas this causal relationship could not observed from the group with high level of leisure constraints. Nevertheless, it indirectly and positively caused IPLA though LCN for the same group. This implies that the mediative role of LCN became more important as the level of leisure constraints became more restrictive. Further, we separately showed that the role of LIS was important in the process of LCN.

This study of the Wholeness Program relevant to dementia behavior and verification of buffering effects. For the purpose of this, among those who were attending Day Care Centers belonging to Seniors Welfare Center of M1 and M2 located in Seoul. Among those who met all these requirements, 40 senior citizens were finally selected. After carrying out a preliminary test to the selected subjects, 20 elderly of Seniors Welfare Center of M1 were randomly placed as an experimental group, while other 20 people of Seniors Welfare Center of M2, as a control group. The Wholeness Program relevant to dementia behavior was carried out from March 14 to May 30 of 2016, for 12 weeks, twice a week. As for the measurement tool, this study depended on the Korean version of Mini Mental State Examination (MMSE-K), the Korean version of Modified Barthel Index (K-MBI) and the Korean version of Geriatric Depression Scale (GDS-K). While the elderly were participating in the Wholeness Program relevant to dementia behavior, they were measured two times in total, before and after the participation in dementia behavior. Based on SPSS-PC (version 21.0), firstly, independent t-test was carried out to understand the homogeneity between the experimental group and the control group. Secondly, matched-pair t-test was carried out between preliminary test and post-test to inquire into the effects of MMSE-K, K-MBI and GDS-K. Thirdly, ANOVA was conducted to confirm the variation (change amount) between preliminary test and post-test. According to the survey results, the Wholeness Program relevant to dementia behavior of the elderly shows overall effects in all spheres of changes of cognitive ability (MMSE-K), changes of physical capacity (K-MBI) and changes of depression level (GDS-K).

This study was conducted to test the effects of participation in 12-week program of boxing aerobics by obese middle-aged women on their body composition, blood constituents, and vascular compliance The samples are the middle-aged women in their forties or more, who has 30% or more body fat percentage, but has no medical history in cardiovascular disorders or metabolic diseases. The samples are divided into 8 of exercising group, and 8 of control group by random assignment. The intensity of boxing aerobics was HRmax 50% for the initial 4 weeks, HRmax 60% for the 5th to 8th week, and HRmax 70% for the 9th to 12th week. Each session took 60 minutes. The result is as follows. First, as a result of participating in the boxing aerobics program, body weight, body fat percentage, and muscle showed significant differences depending on the measuring period and the interacting term of the group and measuring period(p<.001), and the result of t-test on the sample matched to each group's measuring time also showed the significant increase or decrease in the exercising group(p<.001). Second, as a result of participating in the boxing aerobics program, the exercising group's TC, TG, HDL-C, and LDL-C, all showed significant differences in accordance with each group, measuring time, and the interaction term between groups and measuring time(p<.01, p<.001), and the result of t-test on each group's samples matched to the measuring time also shows significant increase or decrease in the exercising group(p<.01). Third, as a result of participating in the boxing aerobics programs, the vascular compliance of right hand, left hand, right hand, and left hand showed significant differences in accordance with each group, measuring time, and the interacting term between the measuring time and the group(p<.001), the t-test results of the samples matched to the each group's measuring time also showed significant differences in the exercising group(p<.001). To summarize the results above, it is suggested that the 12-week boxing aerobics program can improve body composition, blood constituents, and the blood circulation, which may prevent or enhance relevant diseases such as cardiovascular disorders.

The purpose of this study is to identify how postural mechanics affects postural control on balance and stability by using frequency analysis technique from the kinematic data acquired during the one leg standing posture. For this purpose, the experimental group consisted of two groups, the normal group (n=6) and the national Gymnastics group (n=6). Displacement data of CoP were analyzed by frequency analysis of rambling (RM) and trembling (TR) by FFT signal processing. As a results, there was a significant difference in evaluating the stabilization index between the two groups with the eyes open and closed one leg stnading (p <.05). The cause of the difference was found to be the output of the maximum amplitude of RM (f1) and TR (f2) (p <.05). In particular, in the low frequency RM of 8-9 Hz, which is a natural frequency of signal wave involved in postural feedback feedback, the main frequency appeared to be performs the exercise mechanism of stable brain posture control. And in the high frequency TM of 120-135 Hz, it is considered that the adaptation of the reflective muscle response is minimized to minimize posture shaking. In conclusion, this study provides evidence for the intrinsic main frequencies according to the postural control ability which affects the CNS in one leg standing.

There is a large body of literature that studies serious leisure participants in a wide range of activities. By comparison, casual leisure has received scant attention, bearing few empirical studies. And serious leisure is often cast in an superior role in comparison with casual leisure for optimally healthy or beneficial leisure. The purpose of this study is to investigate the psychological functioning of 'casual leisure-serious leisure'. Especially, we pay more attention to reveal the positive functioning of casual leisure. It draws findings from the data of 291 university students. The results are as follows. First, in comparison with 'casual leisure group', 'serious leisure group' was showed a higher significant increase in leisure related functioning(leisure satisfaction and leisure benefits such as physical health, relationship and self-controlibility). However, There is no significant inter-group differences in 'self-life functioning variables(positive·negative self-esteem, happiness, quality of life)'. It implies even though serious leisure has more relation to positive leisure experiences, people maintain and enhance their self-esteem and experience satisfaction and happiness of their entire lives through casual leisure participation as much as serious leisure.

By examining the constitutive characteristics of Yon-Ko-Jeon and analyzing the lived meanings and experiencing essence of students, this study details the students' awareness, responses, and strategies with regards to the phenomenon of women's alienation from Yon-Ko-Jeon. Students from the two colleges were divided into two groups- one which was aware of women's alienation from Yon-Ko-Jeon, and another group that was unaware of such a phenomenon. Students without awareness tended to perceive the alienation of women from Yon-Ko-Jeon as a natural phenomenon. On the other hand, the members who had awareness tended to see it as a phenomenon that was either justified, unequal, or in need of change. In the latter group, those who saw women's alienation as a justified phenomenon responded with tolerance and adopted a bystander strategy. Conversely, those who saw it as an unequal phenomenon responded with rejection and instead chose to adopt anti-/alternative Yon-Ko-Jeon strategies. The last group, which perceived women's alienation as a phenomenon in need of change, adopted correcting responses as well as intercollegiate solidarity and cooperation strategies. A generalization of the findings reveals that the students' experiencing essence of the phenomenon extends from critical thinking to awareness, response, and strategy in a step-by-step and sequential process. Through this study, it was found that the students' experiencing essence all follow a continuous thinking pattern, as illustrated in the diagram provided.

This study was conducted by performing intensities aerobic exercise for 12 weeks, three times a week targeting 28 middle aged women. The purpose of this study was analyzing factors which affect cognitive function and changes of blood pressure, renin-aldosterone system, neurotransmitter, cognitive function and working memory after treatment. The participants were divided into three groups which are the control group(n=9, non exercise), moderate intensity aerobic exercise group(n=10, 50%V02max), high intensity aerobic exercise group(n=9, 70%V02max). The two-way ANOVA(repeated measure) and multiple regression analysis were carried out to target those three groups before and after treatment. The results were as follows like this. The moderate intensity aerobic exercise increased renin, brain derived neurotrophic factor(BDNF), cognitive function and working memory. Also, it reduced aldosterone, angiotensinII and aldosterone-renin ratio. The high intensity aerobic exercise showed increase BDNF, cognitive function and working memory and decrease systolic. As a result of a multiple regression analysis of factors affecting cognitive function after intensities aerobic exercise, the moderate intensity aerobic exercise affected diastolic blood pressure, decrease of aldosterone-renin ratio and working memory. Also, an increase of BDNF affected cognitive function, the high intensity aerobic exercise affected working memory BDNF and an increase of serotonin affected cognitive function. Therefore, It could be seen that more than moderate intensity exercise increase woman's cognitive function and working memory. Also, there were metabolic factors which affect the increase of cognitive function. To moderate intensity exercise, renin-aldosterone and working memory affected to increase of cognitive function. For high intensity exercise, BDNF and working memory affected to it.

This study was performed to identify the effects of different intensities of regular aerobic exercise on erythropoietin (EPO) and BDNF levels, and cognitive function and working memory in middle-aged women. Women aged 40 to 60 years residing in G-gu, Y-si, Gyeonggi-do were divided into 3 groups: control group, moderate-intensity aerobic exercise group and high-intensity aerobic exercise. All groups were asked to exercise at the given intensities, twice a week for a total of 12 weeks. Blood samples were collected from participants on week 0 (before exercising), week 6 and week 12, and then cognitive function and working memory tests were followed to measure erythropoietin (EPO) and BDNF levels, cognitive function and working memory. Repeated measures ANOVA, univariate analysis and follow-up test were performed on all data to compare the group, period and interaction through a SPSS. As a result, a significant difference over time was observed in EPO, BDNF, cognitive function and working memory; therefore, a follow-up one-way ANOVA analysis was performed on each group. As a result of analysis, a significant increase in erythrocyte, hematocrit, BDNF level and working memory was observed in moderate-intensity aerobic exercise group while erythrocyte and working memory were significantly increased inhigh-intensity aerobic exercise group. When comparing the results between the groups, the level of hematocrit was shown to be significantly higher in both moderate-and high-intensity aerobic group than the control group and also the higher level of hemoglobin was observed in both moderate-and high-intensity aerobic group comparing to control group. Considering the results of this study, therefore, a 12-week long aerobic exercise at moderate to high intensity positively affected EPO and BDNF levels, cognitive function and working memory in middle-aged women.

Recently K-Pop gained worldwide sensational popularity, no longer limited to the domestic pop music scene. One of the main causes can be that K-Pop mostly are "Hook Song" which has the "hook effect": a certain melody or/and rhythm is repeated up to 70 times in one song so that it hooks the ear of the listener. Also, visual effects by K-Pop dance group are supposed to contribute to gaining the popularity. In this paper, we propose a method which traces the changes of preference for Korean pop music according to the passing of time and investigates the causes using acoustic signal analysis. For this, experiments in acoustic signal analysis are performed on Korean pop music of from popular female singers in 1960s to those as of this date. Experimental results by applying acoustic signal processing techniques show that the periods discrimination is possible based on scientific evidences. Also, quantitative, objective and numerical data based on acoustic signal processing techniques are extracted compared with the pre-existing methods such as subjective and statistical data.
