This study was designed to compare segmental body composition and bone mineral density in spinal cord-injured(SCIS; n=9, SCIA; n=9) and non-injured control(AB; n=9) subjects. Dual-energy X-ray absorptiometry(DEXA) was used to measure %body fat, body fat mass, lean body mass, bone mineral contents, and bone mineral density in total and various body regions(arms, legs, trunk). The present results showed that body fat mass and %body fat were significantly higher and lean body mass was significantly lower in the SCIS group compared to AB group, while there was no difference between the SCIA and AB group in those of parameters. In BMC, there was no difference among groups and in BMD, SCI group was significantly lower that AB group, but there was no difference between SCIA group and AB group. Based on these results, in can be suggested that long-term regular exercise can reduce the negative changes in body composition, bone mineral density by spinal cord injury.

The purpose of this study was to determine the effect of state for training at the VT using other relative physical factors as like a VT-Sec, VT-VO2peak, VT/VO2peak%, VO2peak, VT-HRpeak, VT/HRpeak%, HRpeak, with individuals with spinal cord injuries. The participants were composed of 7 spinal cord injured wheelchair basketball athletes who are involved with regular activity, 5 spinal cord injured sedentaries who are not involved any regular activity. The statistical procedures used to the analysis were unpaired T-test. The results were as follows; First, the significant differences in VT-Sec, VO2peak were observed between 2 groups. Second, the validity of 44-72VT/V O2peak% and 56.78VT/HRpeak% is suggested as an alternative exercise intensity by individuals with all spinal cord injuries.

황부근(Boo Geun Hwang),이재현(Jae Hyun Lee) 한국사회체육학회 2013 한국사회체육학회지 Vol.0 No.53
This study investigated the relationship between physical fitness(PF) and autonomic activity measured by heart rate variability in 46 women(30.8-58.4 years). PF included both of health and exercise function related ones. The results showed significantly positive correlation between muscular endurance(ME) and parasympathetic activity(RMSSD and logarithmic high frequency level(HFlog). Response time(RT) also showed significantly negative relationship with RMSSD, HFlog, and logarithmic total power. As a result of comparison of PF among 4 groups distributed by HFlog, the group with 50-75 percentile level of HFlog showed significantly superior ME and RT than 0-25 percentile group. In conclusion, ME and RT were related to parasympathetic activity in adult women and these PF factors are most superior in women with optimally not excessively activated parasympathetic system.
젊은 성인 남자의 최대산소섭취량 수준과 심박변이도 및 운동 후 심박수 회복율의 관련성
황부근(Boo-Geun Hwang),변재종(Jae-Jong Byun),이재현( Jae-Hyun Lee) 한국생활환경학회 2016 한국생활환경학회지 Vol.23 No.5
This study investigated the relationship between the level of maximal oxygen uptake (VO2max) and the function of autonomic nervous system (ANS) in 30 young male adults. The function of ANS was measured by heart rate variability (HRV) and the post-exercise heart rate recovery (HRR). The results showed that there was a significant relationship between VO2max and HRV, but not between VO2max and HRR. Furthermore, the group of higher VO2max showed higher SDNN, RMSSD, TPlog, VLFlog, LFlog, HFlog level and lower physical stress index than those of the group of lower VO2max. In conclusion, there is a significant relationship between VO2max and the function of ANS measured by HRV in young male adults and it seems that the aerobic capacity measued by VO2max might affect HRV positively.
韓國産 수리거미科(Gnaphosidae Pocock,1898)의 分類學的 再整理
정부근(Boo-Geun Jung),김주필(Joo-Pil Kim),송란주(Ran-Joo Song),정종우(Jongwoo Jung),박영철(Young Chul Park) 한국거미연구소 2005 한국거미 Vol.21 No.2
Pocock, 1898 에 의해 최초로 기록된 한국산 거미가 수리거미과여서 한국 수리거미과는 거미연구사에서 중요한 의미를 지니고 있다. 하지만, 그 역사적 의미에 비해서 그 분류학적 연구는 미미한 실정이다. 한국에서 수리거미과에 속하는 거미는 종다양도가 높은데, 현재까지 전체 19 속이 밝혀져있다. 이번 연구에서 우리는 종다양도와 한국거미연구사의 측면에서 수리거미과를 재정리하였다. 한국에서는 19 속 44 종이 밝혀져 있는데 이들 모두를 여기서 다루었다. The spiders of the family Gnaphosidae take a very significant position from the historical point of view since the studies on spiders in Korea strated from the family Gnaphosidae Pocock, 1898 in 1907. Despite its historical meaning, however, taxonomic studies on the spiders of the family Gnaphosidae have been poorly conducted to date. In Korea, the spiders of the family Gnaphosidae are rich and diverse, and a total of 19 genera belong to the family. In this study, we reviewed the spiders of the family Gnaphosidae, an important group from the aspect of species diversity and from the historical point of view in the Korean aranchnology. There are 44 species of the 19 genera currently recognized in Korea, and all of them are included in the review. While reviewing the articles including the original descriptions, we found some terminologies not in agreement according to authors of the articles, especially in the terminologies used to describe the body parts of type - speciemen. In addition, a genus has been no its own Korean nomenclature though there is a scientic name of the genus. Paik placed Poecilochroa coreana, a speces called "Solgaeguemi" in Korean, into the genus Kishidaia in 1992. However, the Korean name of the genus has not been generated yet in the family Gnaphosidae. Thus, the Korean nomenclature of the genus Kishidaia has been newly designated as the genus "Kisidaguemi" in this study. From the evolutionary point of view, our review of the family Gnaphosidae, based on the original articles describing the type speciemens, will contribute the construction of the morpholo-anatomical database to understand the phylogenetic relationship among the genera of the family Gnaphosidae.

Purpose: This study aimed to identify the effect of weight training on anaerobic power, muscular strength and muscular endurance in wrestlers when having different duration of rest between sets. Method: The participants were 21 wrestlers; they were divided into 60 second rest group of 7, 90 second rest group of 7 and 120 second rest group of 7. Weight training was conducted for 12 weeks. All 3 groups conducted 15 repetitions of 3 sets with 50% of 1RM on 1-2 week, 15 repetitions of 3 sets with 70% of 1RM on 3-7 week and 15 repetitions of 4 sets with 70% of 1RM on 8-12 week. SPSS 23.0Program was used for data processing and two-way ANOVA with repeated measure was conducted at the .05 significance level. Result: The result of this study is as follows. For peak torque among groups, it was significantly higher on extensor and flexor muscle of elbow joint in 120 second rest group than 60 second rest group, and that on extensor muscle of trunk joint was significantly higher in 120 second rest group than 90 and 60 second rest groups. For muscular endurance among groups, it was significantly higher on extensor muscle of shoulder joint in 60 second group than 120 second rest group, and that on extensor muscle of trunk joint was significantly higher in 60 second rest group than 90 and 120 second rest groups. Peak power was higher in 60 and 90 second rest groups than 120 second rest group.
