Purpose of this study is to compare and analyze effect of exercise intensity in complex training for 8 weeks on leptin, growth hormone, IGF-1, and body composition in middle school with intellectual disability. Subjects of this study were 26 middle school students, 9 in high-intensity group, 9 in middle-intensity group, and 8 in low-intensity group. To compare the difference from different exercise intensity, pre-value before training has been set as covariate and different exercise intensity has been set as independent variable, with changes in leptin, growth hormone, IGF-1, and body composition. Analysis of covariance (ANOVA) has been performed for data analysis and effect size ${\eta}^2$(eta) has been deduced. Result acquired from analyzed data is as following. First, when equal exercise has been imposed on middle school students with intellectual disability, in regard of exercise intensity, it was shown that leptin most decreased in middle-intensity, growth hormone most increased in middle-intensity, and IGF-1 increased in low-intensity. Second, in regard of body composition, low-intensity was most effective in increase of total body weight without fat. Decrease of body fat was most prominent in middle-intensity and increase of bone density, in low-intensity. Also, in further studies, study that differentiates subjects in gender and individual exercise performance is deemed mandatory.

The present research was conducted to investigate the effect of moderate exercise training on splenocyte inflammatory cytokines production in high fat diet-induced obese mice. To determine the effects of exercise training and low fat diet on splenocyte, C57BL/6 male mice (4 weeks aged, n=20) were fed a high fat diet (45% fat diet) for 5 weeks so that obesity was achieved intentionally. These obese mice were then divided into 2 groups; HLC (low fat diet and control n=10), and HLE (low fat diet and exercise n=10). HLE mice performed 8 weeks of exercise training on a motorized treadmill by running for 30-60 min/day at 10-22 m/min, 0% grade, five times per week. After exercise training, all the splenocyte was collected and Con A (concanvalin A, 10${\mu}g/ml$) was used to stimulate the cells, after which IL-1${\beta}$, IL-6, TNF-${\alpha}$ were measured by bio plex. Independent t-test was used and p value under 0.05 was considered a statistical significance. Splenocyte IL-1${\beta}$, IL-6, TNF-${\alpha}$ production of HLE stimulated by Con A was significantly lower than that of HLC (p<0.01). These findings suggest that moderate exercise has beneficial effects on splenocyte inflammatory cytokines in high fat diet induced obese mice.

This study examined the effects of song-based group music therapy on the exercise stress and positive psychological capital of youth soccer players. Eighty youth soccer players were assigned to either a song-based music therapy group or a control group. For the analysis of the effects of song-based group music therapy, the Exercise Stress scale and the Athlete Positive Psychological Capital scale were administered before and after the intervention. The collected data were analyzed using an independent sample t test and paired t test. The results were as follows. First, the experimental group showed a significantly lower posttest score on the exercise stress measure than the control group (p < .01). The control group showed a significant increase from pretest to posttest on the exercise stress measure (p < .05). Second, the experimental group scored significantly higher at posttest than the control group on the positive psychological capital measure (p < .01). The control group demonstrated a statistically significant decrease from pretest to posttest on the positive psychological capital scale (p < .05). The results suggest that song-based group music therapy is an effective treatment method that lowers exercise stress and raises positive psychological capital of youth soccer players.

This paper attempts to explore the development of the media labor movement and its tasks. Due to the unique characteristics of information delivered by media, the media labor movement under the authoritarian regime was oppressed and regulated by the government. As democratization has proceeded, the state's oppression and regulation of media has been weakened. However, media workers should wage the struggle for union recognition and independence of editorship simultaneously. Because media unions as labor market organizations also seek for job security and wage increase, we need to understand both political dimension and economic dimension of union activities in media industry. While state's control over media has been diminished in the late 1900s, competition in media industry has been intensified. As small number of media corporations monopolizes the media market, the ecology of media has been completely transformed. Unions in media industry should respond to the change of the media ecology and should build solidarity among media workers at the same time. The achievement of the public nature of media as a part of democratization and building union federation of media industry as a response to the marketization of media still remain as an epochal task for media unions. Like the case of "Hope Bus" in the strike in Hanjin Heavy Industrial Corporation, solidarity between citizens and striking workers should be strengthened.

This research has been conducted to determine the effect that the visually handicapped's participation in an aerobic exercise program has on cardiorespiratory function and arterial pulse wave. The subjects of this research were 20 people who have a 1st degree visual impairment. They recognized the purpose of this research and agreed to take part in it. After receiving agreements from their guardians, we divided them into an exercise group of 10 and a comparison group of 10 at random. The exercise group conducted a 50-70%HRmax treadmill exercise for 60 minutes a day, five times a week, for 12 weeks, including warm up and warm down exercises. We then conducted a two-way repeated ANOVA, which regards the period of exercise and the two groups as independent variables. The follow-up verification for exercise periods according to each group was carried out with a paired t-test. The statistical significance level was p<.05. The following are the results of this research. First, the weight and body fat of the experiment group after exercise show a meaningful reduction compared to before the exercise program (p<.05).Second, the VO2max, HRmax, and VEmax of the experiment group after exercise show a meaningful increase compared to before the exercise program (p<.05). Third, the arterial pulse wave of the experiment group after exercise display a meaningful increase compared to before the exercise program (p<.05). Fourth, the systolic blood pressure of the experiment group after exercise does not show a meaningful reduction compared to before the exercise program (p>.05). These results prove that the visually handicapped's participation in an aerobic exercise program is effective in the improvement of their cardiorespiratory function, bloodstream circulation function and blood vessel function.

The aim of this study is to closely examine the changes in their metabolic syndrome index and autonomic nerve systems after the 16-weeks's combined exercise program is carried out on low-level physical strength group (PAPS 4-5 level students). They were divided into two groups; exercise training group (15) and control group (15). This program consisted of five-times-a-week's warm-ups, main activities and warm-downs and it takes 50 minutes per trial. Through SPSS 19.0, all averages and standard deviations of dependent variables were calculated. We first performed Shapiro-Wilk's normality test of the variables. Before verifying the effect of combined exercise program, we tested the equality of means of the variables between combined-exercise-programmed-group and control group through a two-sample t-test and carried out a paired t-test to check if the changes in the variables of two groups before and after 16 weeks are statistically significant. Every statistical test is performed at a significance level of ${\alpha}$=.05. The results are as follows. When it came to metabolic syndrome index, there were statistically meaningful changes in waist measurement, triglyceride, glucose with empty stomach and HDL-C. Also, when it came to autonomic nerve system, there were meaningful changes in all variables. Consequently, it seems that the 16-weeks combined exercise program has positive effects on low level physical strength students.

Hyochang Park was the royal tomb of the Joseon Dynasty, where were the tombs of Prince Munhyo and his birth mother Ui-bin Seong, king Soonjo's concubine Sook-Ui Park and Youngon princess by a concubine. It was upgraded from Hyochang tomb to Hyochangwon at King Gojong. The Japanese imperialism destroyed Hyochangwon and made it into a park, also moved to Seosamneung in 1944. After returning from Chongqing after liberation, Kimgu made the independence movement tomb in the empty space of Hyochang Park. There were 3 martyr's tomb, provisional government figure tomb. Kimgu himself was buried in Hyochang Park after his death in 1949. During the regime of Rhee Seung-man and Park Jeong-hee, there was a constant attempt to change the identity of Hyochang Park, where independence activists were buried. Hyochang Stadium, Wonhyo buddhist priest's Statue and North Korean Anti-Communist Tower were established. After democratization in 1987, the independence activist tomb of Hyochang Park began to gain meaning again. The 6th Republic succeeded the provisional government in the Constitution, also the national cemetery and independent park of Hyochang Park were attempted but the social consensus could not be achieved. This study focuses on the historical middle layer and symbolism of Hyochang Park and aims to contribute to social consensus on the identity of Hyochang Park by making a storytelling on the theme of 'Independence Road'.

Recent development in seeker technology explores a new seeker design in which, with larger field-of-view (FOV), optical parts are strapped down to a body (hence, called as a body-fixed seeker or a strapdown seeker). This design has several advantages such as comparatively easier maintenance and calibration by removing complex mechanical moving parts, increasing reliability, and cost savings. On the other hand, the strapdown seeker involves difficulties in implementing guidance laws since it does not directly provide inertial LOS rates. Instead, information for generating guidance commands should be extracted by estimating missile/target relative motion utilizing target images on the image plane of a strapdown seeker. In this research, a new framework based on an unscented Kalman filter is developed for estimating missile/target relative motion on the simplified assumption of a point source target. Performance of a terminal guidance algorithm, in which guidance command is generated based on the estimated relative motion, is demonstrated by a missile/target engagement simulation.

Purpose: The purpose of this study was to elucidate the role of Korean women nurses in the independence movement and to examine their activities during the Japanese occupation from 1910 to 1945. Methods: Nurses studied were women nurses referred to as Ganhowon, Ganhobu, Gyeonseupganhobu, Sanpa, and Josanbu at that time. Five participants such as descendents or relatives of nurses who participated in independence movements, were selected for interview to provide oral historical materials. An historical research approach was used and all of the data were analyzed according to period, region, and pattern of the independence movement. Results: Throughout the historical literature and oral historical materials, it was found that from 1914 to 1945, thirty-eight women nurses actively participated in various types of independence activities such as mass hurrah demonstrations, raise the spirit of war, red cross activities, enlightenment movement and armed struggle to encourage the public to stand up against Japanese imperialism locally and abroad. Conclusion: The findings indicate that women nurses, as enlightened women, endeavored to solve social issues with their autonomous volition, and these action can serve as meaningful evidence for enhancing the social status of nurses.
