In December 2017, a fire at the Jecheon Sports Center caused 29 deaths and 40 injuries, and about 2 billion won in property damage. It is a facility used by unspecified people as a publicly used establishment with a piloti structure. The damage was expanded due to the ignition of combustible exterior materials, Lack of fire protection in horizontal and vertical penetrations. Although legislation has improved since the fire, it is not retroactively applied, increasing the risk of fire in existing buildings. Accordingly, it is necessary to examine the case of the Jecheon Sports Center fire and draw out the problems. In this study, the fire simulation results and the Jecheon Sports Center fire are comparatively analyzed and used as basic data for fire reduction measures in publicly used establishment. As a result of the fire simulation drive, in the case of the second floor, the room temperature exceeded the human life safety standard of 60 ℃ after about 700 seconds had passed. In the case of three floor, it is predicted that the indoor temperature will exceed about 350 ℃. and temporary complexation will occur in the indoor combustibles.

In previous studies, fire simulation was used to estimate the fire spread path. According to previous studies, the fire spread path was estimated to be the main staircase, but consideration of interior materials and internal bulkheads was insufficient. In this study, the ignition time of the 3rd layer was analyzed using the prediction formula considering the interior materials and internal bulkheads. As a result of referring to the architectural drawings, it was found that the interior material of the 3rd floor was made of polystyrene. The internal ignition time of the third floor using FDTs was calculated to be 14,070 seconds (about 234 minutes). The internal ignition time of the 3rd floor using the Handbook on Design Calculation Methods of Fire Behavior was calculated to be 3,104 seconds (about 51 minutes). As a result of calculating the ignition time through the predictive formula, there is a large difference in the ignition time, so it is necessary to review the condition of the variable as a result of the calculation in the future.

The purpose of this study was to examine the relationship among women's leisure dance participation, physical image and self-esteem. The subjects in this study were 300 female adults who were selected by cluster sampling from the population that consisted of women who were in their 20s to 50s. In the population, some women got leisure dance at fitness clubs, sport lovers' clubs and dance academies in Seoul and Gyeoggn Province as of 2009, and the others didn't. As for the reliability of the questionnaires used in the study, the Cronbach alpha coefficient of the questionnaires was above .70. The major statistical methods utilized in this study were Frequencies, reliability factor analysis, analysis covariate, regression analysis and path analysis. The findings of the study were as follows: First, the women who got leisuer dance evaluated their own physical image and self-esteem more favorably than the others who didn't. Second, the length of participation affected the body shape, satisfaction level and flexibility, and the intensity of participation impacted on the body shape and muscular power. Third, the length of participation had an impact on self-esteem, and the frequency of participation exerted a negative influence on that. Fourth, the degree of participation had a causal impact on physical image and self-esteem. In other words, the degree of getting leisure dance affected self-esteem in a firsthand manner and exerted a secondhand influence on that through physical image as well. The findings of the study suggested that physical image was one of major parameters to link participation in rhythmic exercise and self-esteem.

This study was conducted in order to investigate body awareness and dietary life according to gender. Subjects of the study were 120 men and 127 women aged 20 to 30 years, who exercise regularly at a fitness center in Seoul. The subjects were asked to fill out a questionnaire on body awareness, reason for regular exercise, dietary behaviors, and nutrition knowledge. The percentage of overweight and obesity was 69.2% in men, and 25.2% in women. The percentage of subjects who considered themselves as overweight was 38.3% in men and 59.8% in women. Intake of protein in men was higher than the recommended nutrient intake (RNI). Intake of energy in women was lower than the estimated energy requirement (EER). Men who considered themselves as overweight showed lower energy intake than men who considered their body weight as under and normal, whereas no difference in energy intake was observed between women who considered themselves as overweight and women who considered their body weight as under and normal.

The purpose of this study was to investigate the effects of gender difference in injury experience on biomechanical variables of lower extremity during two leg drop landing. 20 male(injury experience=8, non-injury experience=12) and 20 female(injury experience=11, non-Injury Experience=9) in their 20's were selected as subjects. Two-way mixed ANOVA was performed on the biomechanical variables obtained from the two leg drop landing in a 45cm height box and post-test was performed with bonferroni adjustment(p <.05). The results of this study suggest that the group of female who injury experience could induce the reduction of the peak vertical ground reaction force by increasing the valgus and internal rotation of the knee joint and flexion and internal rotation of the hip joint. In the INE(injury non-experienced) female group, the peak knee flexion angle was the smallest, as well as the flexion of the hip joint and the external rotation angle, and the peak vertical ground reaction force was the highest. On the other hand, the INE female group showed high vertical ground reaction force because they did not utilize the knee and hip joints relatively than the IE(injury experienced) female group, this means that it is relatively exposed to the risk of injury. Therefore, it was found that gender difference in injury experience is a factor affecting factors of knee and hip joint movement and peak vertical GRF(ground reaction force).

This study aimed to compare functional recovery after rehabilitation exercise between isolated PCL reconstruction and combined PLC reconstruction. Patients were divided into two groups: those who had isolated PCL reconstruction (n = 16) and those who had combined PLC reconstruction (n = 16). We assessed knee joint ligament laxity, subjective questionnaires, and isokinetic muscle function before, after 12, and 24 weeks of a rehabilitation exercise program. In both groups, there were significant differences in knee joint laxity (p = 0.048), IKDC subject score (p < 0.001), Lysholm knee (p < 0.001), Tegner activity scale (p = 0.027), and isokinetic muscle deficit (p = 0.040) by estimated period. However, no significant difference between groups was observed (p > 0.05). These results suggest that rehabilitation exercise after isolated PCL and combined PLC reconstruction influenced structural, subjective, functional recovery positively.

Korea's golf fever is as good as the United States, Europe and Japan, which are called golf powers. The senior golf population over 55 years old has exceeded 2.5 million, and they are more interested in improving golf performance than participating in golf. So, this study aims to emphasize the importance of dynamic preparation exercise by identifying the effects of dynamic preparation exercise on golf physical strength and golf batting in order to suggest a way to help the elderly men's golf performance. The experimental group(n=13) and the control group(n=14) were divided into two groups and repeated measurements were conducted by two-way ANOVA with pre- and post-design. As a result of the analysis, the flexibility factor showed a positive effect on golf physical strength, and in golf batting, head speed, distance, and attack angle showed interaction effect, which led to the conclusion that dynamic preparation exercise helped the golf performance of the elderly male. Therefore, the continuous dynamic preparation exercise led to positive transition to head speed and attack angle due to the increase in the flexibility of the body, which led to the improvement of distance and the increase in performance level.

This study is a phenomenological study conducted to gain a deeper understanding of the positive psychological capital experience of the elderly women who participated in the long-term movement. In Korea, women are eight years older on average than men, and two-thirds of the elderly in need are women, so research on the issue of women and senior citizens is urgent. The research participants include seven female senior citizens from the Seoul-based sports center. The data collection was conducted through in-depth interviews once for 90 to 180 minutes and twice per participant from March to May 2020, and was analyzed using the phenomenological research method of Colaizzi. The analysis results showed that regular life, relationship and interest life, changing life, and satisfying life were factors that acquired and developed positive psychological capital for elderly women, which were possible only if they maintained their health, regularity and relationship. The experience of participants who achieved successful aging by acquiring positive psychological capital through exercise is suggested as a solution to aging social problems, and furthermore, it is expected to serve as a healthy guide for successful aging for young and old people ahead of their old age.
