        본 연구는 24주간의 축구영재 프로그램을 실시하여 초등학생(저학년, 고학년)의 신체조성, 기초 체력, 자기조절능력 및 자기효능감에 미치는 영향을 구명하기 위하여 남자 초등학생 80명을 대상으로 저학 년 40명, 고학년 40명으로 구분하여 실시하였다. 축구영재 프로그램은 주 1회, 24주간 실시되었으며, 측정된 자료의 그룹 내 변화는 대응표본 t-검정, 그룹 간 차이는 독립표본 t-검정을 이용하여 비교 분석하였다. 또한, 그룹과 시기간의 상호작용 효과 검증을 위하여 이원반복측정분산분석을 실시하였다. 그 결과, 신체조성 중 근육량은 두 그룹 모두 유의하게 증가하였고, 그룹 간 유의한 차이가 나타났으며, 체지방량은 유의하게 감소하였다. 기초체력은 모든 변인에서 두 그룹 모두 유의하게 증가하였고, 심폐지구력, 근력, 순발력에 서 그룹 간 차이가 나타났다. 자기조절능력과 자기효능감은 두 그룹 모두 유의하게 증가하였으나, 그룹 간 차이는 나타나지 않았다. 축구영재 프로그램은 초등학교 남학생의 신체조성 및 기초체력 증진에 긍정적인 영향을 미쳤으며, 자기조절능력과 자기효능감을 높이는데 효과적인 것으로 사료된다.

        백령버섯 병재배용 배지 주재료는 콘코브 배지보다는 미루나무톱밥 배지 처리구에서 발이 및 생육특성이 가장 양호하였으며, 배지 영양원으로는 면실피, 면실박, 밀기울, 옥수수분, 미강 등이 적합하였고, 배지 혼합 비율은 58% 이내 범위에서 재료별로 질소함량을 고려하여 가감 사용하는 것이 적당하였으며, T-N 함량이 높은 면실박 사용량은 20% 수준으로 조절할 필요가 있었다. 또한, 배지 첨가제는 탄산칼슘 처리가 소석회 처리보다 양호하였으며, 무처리구의 경우 갓과 대의 탄력성은 감소하고 경도는 증가되는 경향을 보였다. 따라서, 백령버섯 병재배용 최적배지는 미루나무톱밥+면실피+면실박+밀기울+옥수수분+탄산칼슘이 40:20:20:15:3:2의 혼합 비율로 조성되는 처리구였다.

        The present study was designed to investigate health-related life habits, food preference, body composition for proper dietary habits, health promotion of communities in Incheon area. The effects of personal characteristics and health-related life habits such as gender, age, having breakfast, smoking, drinking, and exercise were analyzed using a surveying. 961 community subjects (262 males and 699 females) were investigated using a questionnaire and Inbody. Data were analyzed by descriptive statistics, chi squared test, and one-way ANOVA (analysis of variation) with SPSS/WIN 21.0. The result of gender distribution showed there were 262 males and 699 females, and with respect to the effect of gender on healthrelated life habits, smoking, drinking, and exercise showed significant differences (p<0.05), whereas having breakfast was not significantly difference (p>0.05). Therefore, the present provide evidence of a relationship between health-related life habits and gender. Regarding the effect of BMI on health-related life habits, exercise showed significant differences (p<0.05), whereas smoking, drinking, and having breakfast were not significantly difference (p>0.05). Thus, the present study also provides evidence of a relationship between health-related life habits and BMI. Our analysis shows that food preference and body composition were significant different from health-related life habits such as smoking, drinking, exercise, and having breakfast (p<0.05). Our analysis showed that body composition was significant differences from health related habits such as smoking, drinking, exercise, and breakfast (p<0.05). In conclusion, the present study suggests that diet guidelines support and improve health promotion designed by communities.

        The purpose of this study is to verify a correlation between flexi-bar exercise and improvement of trunk strength and body composition in juvenile soccer players. The subjects were 11 teenager juvenile soccer players who conducted flexi-bar exercise half an hour daily three times a week for eight weeks. They were tested for trunk muscles strength, body composition and correlation. The result showed that trunk muscles strength improved significantly( p<.01) and weight, Rt. arm muscle mass, Rt. leg muscle mass, and Lt. leg muscle mass(p<.05), Lt. arm muscle mass, trunk muscle mass, and body muscle mass(p<.01) improved significantly as well while Lt. arm fat mass, Rt. leg fat mass, and Lt. leg fat mass decreased significantly(p<.05). In the correlation analysis, the more trunk muscle mass and trunk muscles strength increased, the more muscle mass of body regions increased, which was a positive correlation whereas fat mass of body regions decreased, which was a negative correlation. It was verified that there was a correlation between flexi-bar exercise and improvement of trunk muscles strength and body composition for juvenile soccer players.

        Antler of deer have been used in Asia as a dietary supplementary or alternative medical substance. The antler contains various biological active substances, including ganglioside has been known to promote growth, bone hyperactivity, immune function, protein synthesis and various pharmacological action. Therefore, this study was to investigate the effect of antler on productivity of broiler chicks. Feeding trial has a number of 240 broiler chicks was conducted to investigate the effect of antler extract (AE) treated feeds on body performance, breast meat composition and characteristics in broilers. Each treatment had 15 chicks with 4 replications. The supplementation level of AE treated feeds was 0.3, 0.6 and 0.9% in the experimental diets. The results obtained were summarized as follows: Average body weight gain was significantly (p<0.05) increased in broilers fed with AE compared to that of control during overall periods. Especially, the body weight gain of 0.9% AE treated chickens showed highly increased by 6.0% compare to the control. Average feed intake was not significantly different among the treatments. Average feed efficiency was significantly (p<0.05) improved by 4% in broiler chicks fed with AE compare to that of control. Average breast meat composition and concentration of cholesterol were also not different by feeding the AE. In breast meat characteristics, the shear force (kg/0.5inch2) of breast meat showed similar results in all treatments. The cooking loss of breast meat was significantly lower in the chick fed AE than that of control. But the water holding capacity (%) of breast meat was significantly (p<0.05) higher in the chicks fed AE than that of control. In breast meat color of chicks were not significantly different in all treatments. The thiobarbituric acid reactive substances (TBARS) and volatile base nitrogen (VBN) value were not showed different with all treatments. Also, the fatty acids composition of breast meat were showed similar results in all treatments. In conclusion, the dietary feed of AE tended to improve the body weight gain and feed efficiency, but did not influenced breast meat characteristics of broiler chicks

        The purpose of this study was to investigate the effect of combined exercise training during 12weeks on physical fitness, body composition and bone mineral density in university students. Nineteen male university students who were enrolled of 1st grade at department of physical education in Korea National University of Education were participated in this experiment. Subjects were performed combined exercise training - running, physical training using plyometrics and resistance training - of 5days per week, 70min per 1 time, during 12weeks. The measurement items were health related fitness(muscle strength, muscular endurance, cardiovascular endurance, flexibility), motor skill fitness(power, balance), body composition(% body fat, muscle mass) and bone mineral density(T-score). On the basis of the results analyzed in this study and consideration of many pre studies related it, the result were as follows. First, data analysis of 12 week combined exercise training on health related fitness, post level was revealed more significant increase than pre level at muscle strength(p<.05), muscular endurance(p<.05), cardiovascular endurance(p<.001) and flexibility(p<.05). Second, data analysis of 12 week combined exercise training on motor skill fitness, It was not revealed significant differences between the pre and the post level of the power and balance). Third, data analysis of 12 week combined exercise training on body composition, post level revealed more significant improvement than pre level at muscle mass(p<.05), but It was not revealed significant differences between the pre and the post level of the % body fat. Fourth, data analysis of 12 week combined exercise training on bone mineral density, post level revealed more significant improvement than pre level at T-score(p<.05). In conclusion, It was revealed that 12 week combined exercise training increased physical fitness, and improved body composition and bone mineral density. I hope that more studies will be followed on physical fitness, body composition and bone mineral density on various exercise types, exercise intensity, time and frequency in university students in the future.
