        경피신경 자극과 미세전류신경근 자극이 β-endorphin 과 동통역치에 미치는 영향

        김형남,박래준 대한물리치료학회 1997 대한물리치료학회지 Vol.9 No.1

        The purpose of this study was to examine the amount of β-endorphin and pain threshold according to time sequences in applying experimented TENS and MENS(pre treatment, posttreatment, 25 minutes after the treatment). This test was to aim it showing the effects of the experimental β-endorphin and pain threshold applied to the randomly selected twenty healthy then in their twenties, The subjects were divided into two group(ten for TENS and the other ten MENS). The results obtained are as follows: 1. There was no significant difference in the β-endorphin between TENS and MENS(p$gt;0.05). There was no difference in the pain threshold at pretreatment and posttreatment(p$gt;0.05), but there was some difference at 25 minutes after the treatment(p$lt;0.05). 2. The group of TENS in the experimental β-endorphin had the highest level of 14.40±3.098 at posttreatment, but the level decreased a little according to time passed. And in the experimental pain threshold, the level went to the highest plateau of 2.92±0.483 at 25 minutes after the treatment. 3. The group of MENS in the experimental β-endorphin had the highest plateau of 14.20±3.967 at posttreatment, but the level decreased a bit according to time passed also. And in the experimental pain threshold, the level went to the highest plateau of 2.49±0.617 at posttreatment. 4. There were some differences of the experimental β-endorphin in TENS group at pretreatment and posttreatment(p$lt;0.05). There were some differences in the experimental pain threshold between pretreatment and posttreatment as well as between pretreatment and 25 minutes after the treatment(p$lt;0.05). MENS did not influence the experimental β-endorphin and pain threshold. This experiment showed that TENS increased the levels of the experimental β-endorphin at posttreatment and increased the levels of the experimental pain threshold untill 25 minutes after the treatment. Therefore, the time of sustaining pain in TENS group was longer than that of MENS group. Also, MENS showed hat it increased each level of to experimental β-endorphin and threshold, but these levels were not statistically meaningful.

      • 경피신경 자극과 미세전류신경근 자극이 $\beta-endorphin$ 과 동통역치에 미치는 영향

        김형남,박래준,Kim Hyung-Nam,Park Rae-Joon 대한물리치료학회 1997 대한물리치료학회지 Vol.9 No.1

        The purpose of this study was to examine the amount of $\beta-endorphin$ and pain threshold according to time sequences in applying experimented TENS and MENS(pre treatment, posttreatment, 25 minutes after the treatment). This test was to aim at showing the effects of the experimental $\beta-endorphin$ and pain threshold applied to the randomly selected twenty healthy men in their twenties. The subjects were divided into two group(ten for TENS and the other ten MENS). The results obtained are as follows : 1. There was no significant difference in the $\beta-endorphin$ between TENS and HENS(p>0.05). There was no difference in the pain threshold at pretreatment and posttreatment(p>0.05), but there was some difference at 25 minutes after the treatment(p<0.05). 2. The group of TENS in the experimental $\beta-endorphin$ had the highest level of $14.40{\pm}3.098$ at posttreatment, but the level decreased a little according to time passed. And in the experimental pain threshold, the level went to the highest plateau of $2.92{\pm}0.483$ at 25 minutes after the treatment. 3. The group of MENS in the experimental $\beta-endorphin$ had the highest plateau of $14.20{\pm}3.967$ at posttreatment, but the level decreased a bit according to time passed also. And in the experimental pain threshold, the level went to the highest plateau of $2.49{\pm}0.617$ posttreatment. 4. There were some differences of the experimental $\beta-endorphin$ in TENS group at pretreatment and posttreatment(p<0.05). There were some differences in the experimental pain threshold between pretreatment and posttreatment as well as between pretreatment and 25 minutes after the treatment(p<0.05) MENS did not influence the experimental $\beta-endorphin$ and pain threshold. This experiment showed that TENS increased the levels of the experimental $\beta-endorphin$ at posttreatment and increased the levels of the experimental pain threshold untill 25 minutes after the treatment. Therefore, the time of sustaining pain in TENS group was longer than that of MENS group. Also, MENS showed that it increased each level of the experimental $\beta-endorphin$ and pain threshold, but these levels were not statistically meaningful.

        사관학교 해양스포츠 활성화 방안

        김형남 한국스포츠학회 2017 한국스포츠학회지 Vol.15 No.2

        이 연구의 목적은 해군사관학교에서 실시하고 있는 해양스포츠의 현상을 분석하고 해양스포츠의 활성화를 위한 방안을 수립하는데 목적이 있다. 연구목적을 위해 문헌자료를 수집하였으며 전문가 자문을 거쳐 사관학교 해양스포츠 활성화 방안을 도출하였으며, 이에 따른 결과는 다음과 같다. 첫째, 아직 해양스포츠가 생활체육으로서 정착하지 못한 상태여서 생도 때 체험한 해양스포츠를 임관 후에도 연계할 수 있는 여건이 조성되어야 하며 , 해양스포츠 경기 주최 등 외부와의 교류를 통해 학교를 홍보하고 사관학교의 인지도를 높일 필요가 있다. 둘째, 해양스포츠를 즐기기 위해서는 바다에서 생존능력이 바탕이 되어야 한다. 따라서 장거리 수영 및 생존수영 습득을 통한 자신감을 확보해야 한다. 셋째, 해양스포츠를 즐기려는 생도들의 니즈를 충족시키기 위해서는 고가인 해양스포츠 장비의 확보를 위한 노력이 필요하 다. 넷째, 해양스포츠 활동을 하기 위해서 좋은 환경과 장비들이 준비되어도 생도들을 교육하고 장비를 효율적으로 보 수・유지할 수 있는 해양스포츠 전문가가 더 필요하다. The purpose of this study was to analyze the phenomenon of marine sports in naval academy and establish activation plan of marine sports. This study used literature review and individual interview in order to achieve this purpose. After consulting with experts, the results of activation plan of marine sports is as following. First, Since marine sports have not yet settled down as living sports, marine sports that have been experienced at the time of cadet' life should be linked even after graduation. And it is necessary to raise public awareness of the school through promoting the school to citizens through the marine sports competition. Second, in order to enjoy marine sports, the ability to survive at sea must be grounded. Therefore, confidence for swimming acquisition must be secured. Third, since marine sports equipment is expensive, efforts are needed to secure marine sports equipment to satisfy cadets' needs. Fourth, in order to conduct marine sports activities, there is a need for a marine sports expert who can guide the cadets and keep equipment efficient even if the environment and equipment are ready.

The purpose of this study was to examine the effects of participation motive in marine sports participation on sports immersion and school life satisfaction of Korea Naval Academy Cadets. Using the sampling method of convenience sampling, total of 230 questionnaire was distributed in Korea Naval Academy. Among them, 20 insincere questionnaire were ruled out and 210 remaining were used to analyze. Researched material was analyzed using SPSS 23.0 program to draw frequency analysis, factor analysis, reliability analysis, exploratory factor analysis, correlation analysis and multiple regression analysis. The analysis results were as following. First, participation motive had a partially influence on sports immersion. Second, participation motive had a partially influence on school life satisfaction. Third, sports immersion had a partially influence on school life satisfaction.

        New Semiconducting Copolymers Containing Alkyl Quarterthiophene and Alkoxy Naphthalene Moieties for Organic Thin Film Transistors

        김형남,김윤희,박소민,신성철 한국고분자학회 2014 Macromolecular Research Vol.22 No.9

        A π-conjugated alkyl quarterthiophene-based copolymer was synthesized by a Suzuki coupling reaction,and its optical, thermal, and electrochemical and organic thin film transistor properties were characterized. The copolymersshowed good solubility in common solvents such as chloroform and toluene, etc. The weight average molecularweight (Mw) of PQTHN and PQTON were found to be 9,200 with polydispersity of 1.2 and 30,600 withpolydispersity of 2.39, respectively. The structure of PQTHN and PQTON was confirmed using 1H NMR and FTIRspectroscopy. Solution-processed organic thin film transistors (OTFTs) using PQTON exhibited 6.96×10-4 cm2 V-1 s-1as mobility with an on/off ratio of 2.46×104.
