Identification of animals has been used with an ear tag with dummy code and blood typing has been used for paternity and individual identification in live animals. Various genetic markers are different for breeds of pig and hence, it is necessary to identity the discrete genetic marker in korean native pig. A total of 240 pigs were used to find korean native pig population specific markers that expressed in population of korean native pigs. To identify the individual traceability, 20 animals were randomly chosen and tested for a whole process from being live to slaughter stages. The candidate genetic marker used in the study were 18 DNA microsatellites which were identified in pig genome. The number of alleles of those DNA microsatellites ranged form a minimum of 3 to maximum of 6. The heterozygote frequency ranged from 0.44 to 0.69. Effective number of alleles for each DNA microsatellotes were 2 to 4. By choosing 6 candidate genetic markers among all, the traceability of individual identification was estimated as accurate as 99.99%(p>0.0014), nearly.

한국 투어 프로선수들의 활약으로 기업에서는 골프 선수를 프로모션 도구로 활용하는 경향을 보이고 있다. 이러한 측면에서 골프 에이전트의 활성화를 위한 타당한 방안책을 수립하기 위해 본 연구에서는 골프 에이전트에 소속되어 있는 프로골프 선수를 목적표집법을 이용하여 골프 에이전트 서비스에 대한 중요도와 만족도의 인식 정도를 평가하였다. 특히 결과를 토대로 국내 프로골프 시장에서 골프 에이전트의 서비스가 선수 및 기업이 만족될 수 있는 전략을 수립하기 위한 마케팅 기초자료로 활용하는데 목적을 두었다. 이러한 목적을 달성하기 위해 한국(여자)프로골프협회의 정회원을 모집단으로 선정한 후, 연구의 목적에 적합한 181명(남자=72/여자=109)의 자료를 수집하였다. 그리고 SPSS 15.0의 하위분석 프로그램인 기술통계, t 검증, IPA분석 등을 적용하여 다음과 같은 결과를 얻었다. 첫째, 골프 에이전트 서비스의 모든 하위요인에서 중요도와 만족도에서 차이가 나타났다. 특히 홍보 요인에서 ‘홍보 활동’과 관리에서 ‘해외진출’, 홍보에서 ‘이미지 관리’가 다른 요인에 비해 많은 차 이를 보였으며, 모든 요인에서 음(-)의 값을 보여 골프 에이전트 서비스에서 중요도에 비해 만족도가 낮게 인식되고 있는 것으 로 확인되었다. 둘째, 이를 토대로 IPA분석에서는 계약 요인의 ‘운동전념(Q7)``, 관리의 ‘계약금 협상(Q1)’이 유지 강화의 1사분 면에 필요한 영역으로, 홍보 요인의 ‘홍보활동(Q5)``과 ‘이미지관리(Q9)``, 계약의 ‘구단계약(Q3)‘과 관리의 ‘해외진출(Q8)``이 2사 분면에 집중적인 투자가 필요한 영역으로 평가되었다. 그리고 관리 요인의 ‘은퇴 후 진로(Q4)``와 계약의 ‘재테크(Q6)``가 3사분 면에 재원의 가용여부에 따라 투자 여부가 결정되는 영역으로, 관리 요인의 ‘법률적 관리(Q2)’는 4영역에 지속적인 유지가 되 는 영역으로 평가되었다. 이상의 결과를 기초로 골프 에이전트 관계자는 효율적인 서비스를 위해 영역별 가중치에 의한 필요 한 영역에서 지속적인 투자를, 불필요한 영역에서는 보완하거나 제외시키는 방안으로 서비스를 제공하는 마케팅 전략을 제시 해야 향후 골프 에이전트가 기업 및 골프선수에게 신뢰가 있는 기업으로 발돋움 할 것으로 기대된다. The functional aspects of active roles of Korean professional golfers at home and abroad and their agents have been rising as promotional tools for enterprises. In order to establish proper ways to vitalize the agents for professional golfers from this viewpoint, the purpose of this research is to conduct a comparative analysis on the degree of perception with regard to the degree of importance of golf agents’ services and the professional golfers’ degree of satisfaction with the services that their agents are providing for them and to provide basic data for establishing marketing strategies through presenting proper direction of the agent services in the domestic professional golf market. To achieve this in this research, the regular member players of PGA of Korea were selected as the population and a total of 365 data were collected using the purposive sampling method, and excluding the data not fitting the research purpose, the data collected from 181 respondents (72 males and 109 females) were used for the actual analysis. These collected data were analyzed by applying the descriptive statistics of SPSS 15.0, t-test, and IPA analysis, and the results are as follows. In all the subordinate factors of the golf agents’ services, there were differences in the degree of importance and the degree of satisfaction. Particularly, compared with the other factors, there were big differences in the ‘promotional activities’ in the promotion, and the ‘advancing into overseas markets’ in the management, and the ‘image management’ in the promotion, and they showed negative (-) values in all the items, indicating that the degree of satisfaction with the golf agents’ services was perceived to be lower than the degree of importance of the golf agents’ services. Based on this, the IPA analysis showed that the ‘concentration on exercise(Q7),’ of the contract and the ‘negotiation on down payment (Q1)’ of the management were evaluated to be the realm that needed to be maintained and reinforced, and the ‘promotional activities(Q5)’ and the ‘image management(Q9)’ of the promotion, and the ‘club contract (Q3),’ of the contract and the ‘advancing into overseas markets (Q8)’ of the management were evaluated to be the realm where the investment should be made intensively. And the ‘career after retirement (Q4),’ of the management and the ‘investment techniques (Q6)’ of the contract were evaluated to be the realm where investment should be made according to the availability of resources, and the ‘legal management (Q2)’ of the management was evaluated to be the realm which should be maintained continuously. Based on the above-mentioned results, it is expected that when the persons concerned in golf agents present the marketing strategies of making investments continuously in the realms, with weighted value by realm, where the investments are needed, and supplement or exclude the investments in the realm where the investments are not needed, in order to provide efficient services, they will be able to develop their businesses into reliable enterprises.

조선후기 풍속화에 드러난 국궁의 교육철학적 특질

최석규(Seok Gyu Choi),최봉암(Bong Am Choi) 한국체육교육학회 2010 한국체육교육학회지 Vol.15 No.2

본 연구는 18세기 조선후기 풍속화에서 드러나는 국궁의 정체성 탐구를 통해, 전통문화유산으로서 국궁의 사회·문화적 특성에 내재한 교육철학적 특질을 탐구하고자 한 것으로서 다음과 같은 결과를 도출하였다. 첫째, 조선후기 풍속화의 이해를 통해 본 국궁의 교육철학적 특질은 인재등용과 신분상승의 도구였다. 습사는 원사전쟁무기로서의 효용성이 상존했던 시대상을 대별했기에 조선선비와 양반사대부들의 일상생활로서, 국방의 의무에 대처하기 위한 유비무환적인 필수덕목이었다. 정량궁 쏘기는 무과시취의 통과의례로서 신분상승을 위한 교육수단이었다. 또한 국궁은 경제의 발달에 편승한 신흥자본가들과 중인신분한량들의 유희적이며 일상적인 생활문화였다. 둘째, 예를 중시한 국궁의 유가적 규범과 격식에 얽매이지 않고, 자연을 벗 삼아 유유자적하고자 했던 조선후기의 사회·문화적인 변화를 살펴 볼 수 있다. 특히 현재까지도 금기시 하고 있는 좌궁이 우궁에 비해 자주 묘사된 것은 조선시대가 유가적 전통사회였다는 점에서 새로운 사실이다. 또한 사정조직은 계모임 형태의 조직체 즉, 사포계와 사계좌목을 구성하여 조선사회의 지도층으로서 역할을 담당하였고, 비정비팔은 우리 활 사법의 근간으로서, ``멀리 쏘기``를 위한 기본자세였으며, 정량궁 쏘기는 무과시취의 필수과목이었고, 사법형태는 용약전진하며 발시 하는 특징이 있다. 각궁제조에 수우각을 사용한 것에서 당시 국제간 교역 또한 활발했었음이 유추된다. 습사는 유희적 속성과 전통문화적인 가치관 형성의 양면성을 함께 공유하였고, 대사례는 국가의식행사의 필수적인 요소였다. 셋째, 조선 후기 사회문화적 특성을 내포한 국궁의 교육철학적 가치는 유가적 행동지침인 정정당당함을 사풍의 주요 골격으로 삼는 활쏘기를 통해 협동심과 책임감을 배양하고, 올바른 행동을 통해 예의를 바르게 함은 물론 주종의 질서와 규칙의 존중, 약속의 실행 등과 같은 도덕성을 함양하며, 관용과 자제력을 길러 사회적 지도층으로서의 적응력을 배가시킬 수 있는 교육도구적요소를 함유하였던 것으로 드러난다. The study aims to figure educational and philosophical traits within the scope of socio-cultural characteristics of Korean bow, gukgung, a Korean traditional cultural asset, by examining the identity of Korean bow found in genre paintings in the latter period of the Joseon Dynasty in the 18th century and has generated following results. First, Korean bow was a means of selecting fit persons for higher positions and ascending social status during the Joseon Dyansty, and as Seupsa was used as a weapon during a war, it was necessary for classical scholars and aristocrats to master it in their daily life with an aim to fulfill their responsibility for national defense. Shooting Jeongryanggung was an educational means of ascending social status as a rite of passage in the state examination during the Joseon Dynasty. In addition, Korean bow was a playful daily life culture for newly emerging capitalists and profligates from a lower class who jumped on the bandwagon of development of commercial economy. Second, it well demonstrates socio-cultural changes in the latter period of the Joseon Dynasty when people were not bound by Confucian norm and formality of Korean bow that valued decorum desiring to live free from worldly cares. In particular, the fact that Juagung (left-handed shooting), a taboo even today, was described more frequently than Woogung (right-handed shooting) is noteworthy given that the Joseon Dynasty was a traditional Confucian society. A mutual-aid society was organized acting as the leadership class of the Joseon Dynasty based on Sapogye (Scholar Fraternity) and Sagyejuamok, and Bijeongbipal was the fundamentals of Korean bow and a basic posture for the long shooting. Shooting Jeongryanggung was a mandatory subject in the state examination. The fact that buffalo horns were used in manufacturing Korean horn bows shows that international trade was facilitated at that time. Seupsa contains playful attributes and traditional value system at the same time, and Daesarye was an essential factor in the national ceremony. Third, the educational and philosophical value of Korean bow found in the socio-cultural characteristics during the latter period of the Joseon Dynasty contains educational factors where a spirit of cooperation and responsibility was enhanced through archery that valued fairness, the Confucian code of conduct, decorum was improved through appropriate behavior, morality was further developed through respect for the relation between the master and servant and compliance with regulations and promises and adaptability that social leaders need to have was boosted through the reinforcement of tolerance and the power of self-control.

The purpose of this study was to validate of the parent education participation measurement scale(PEPMS) for golf player using Rasch partial credit model. Establishing content and face validity, 30-item(24-item: autonomy encourage factor, 6-item: exercise information supply factor) and 5-point scale were generated. The scale was administered to 213 golf player. The Rasch measurement computer program, WINSTEPS 4.2.0 was used to analyze the data. Model fit was decided by Infit and Outfit index (≥.60 and ≤1.40). The results are as follow. First 4-point scale was more appropriated than the 5-point scale that was showed the step calibration index increased step by step in each item. Second, the two factors were satisfied by the global fit statistics index as RMSR (Root mean square residual). Third, 2-item in the autonomy encourage factor was selected as the DIF(differential item functioning) between gender, and nothing item in the exercise information supply factor as the DIF between gender. Fourth, one item in the autonomy encourage factor was over the standard item fit (infit=1.40, outfit=1.55). The results indicated that 21 items in the autonomy encourage factor and 6 items in exercise information supply factor were finally selected. This study verified and showed the PEPMS that constructed 27-item and 4-point scale for golf player. In addition, the newly constructed this scale for golf players should be validated to increase external validity.

As such, a job stress survey tool and scale for private security guard"s were developed by surveying 522 private security guards. The first survey questioned 93 people, thus completing a survey tool combined with existing data. The second survey questioned 195 people to define the factor structure and reliability of data based on an exploratory factor analysis. The third survey questioned 234 people to finally develop a job stress scale for private security guards based on a confirmative factor analysis of data. For this process, SPSS 15.0 and AMOS 6.0 programs were used, and the findings of this study are outlined as follows: First, this study produced a scale which consists of a total of 57 questions related to eleven factors including 21 questions based on open-type questions as well as diverse relevant questions. Second, three-time exploratory factor analyses and factor analyses for the confirmation of job stress scale"s factor structure based on the produced scale were conducted, thus completing a total of 20 questions related to two factors(inherent, structural). Third, two-time confirmative factor analyses were conducted based on this completed scale, thus excluding three inherent-factor questions and completing a total of 17 questions related to two factors. Also, to confirm the validity related to potential factors, average variance extracted value, composite reliability, and discrimination validity were confirmed, all proving to meet the criteria. In conclusion, for the surveying of private security guard"s job stress, 17 questions related to two factors(inherent questions:13, structural questions :4) proved to be valid.

트레드밀 지구성 운동이 streptozotocin으로 유발된 당뇨 흰쥐의 뇌에서 PGC-1α, GLUT-1, Tfam 단백질 및 항산화 효소(Cu, Zn-SOD, Mn-SOD)의 발현량에 미치는 영향

Noh-Hwan Park(박노환),Jin Lee(이진),Kook-Hyun Jung(정국현),Bong-Am Choi(최봉암),Hyung-Chae Jang(장형채),Suk-In Lee(이석인),Dong-Soo Lee(이동수),Joon-Yong Cho(조준용) 한국생명과학회 2011 생명과학회지 Vol.21 No.3

이 연구는 지구성 운동이 streptozotocin (STZ)으로 유발된 제1형 당뇨 특징을 가진 쥐 뇌의 글루코스 운반, 미토콘드리아 기능 및 항산화효소 단백질 발현에 미치는 영향을 규명하는데 목적이 있다. 제1형 당뇨 모델 쥐는 50 ㎎/㎏의 streptozotocin을 수컷 Sprague-Dawley (SD) 흰쥐의 복강에 1회 주입하여 생산하였으며 본 실험 시집단은 NON-STZ 집단(n=8), STZ-CON 집단(n=8) 및 STZ-EXE 집단(n=8) 등 3집단으로 구분하여 실시하였다. 트레드밀 지구성 운동은 총 6주, 주 5일, 2주 간격으로 속도를 약 3∼4 m/min으로 점증적으로 증가시켰으며 운동시간은 1주와 3주차에 10분씩 증가시켰다. 분석 결과 혈청 글루코스 수준은 STZ-EXE 집단은 STZ-CON 집단에 비해 현저하게 감소(p<0.05)하였으며 PGC-1α (p<0.001), mtPGC-1α (p<0.001), GLUT-1 (p<0.001), Tfam(p<0.001), Cu,Zn- SOD (p<0.001), Mn-SOD (p<0.01) 경우도 STZ-EXE 집단이 STZ-CON 집단에 비해 현저하게 증가하였다. 이러한 결과는 장기간 지구성 운동이 뇌의 글루코스 이용능력과 관련된 단백질인 GLUT-1과 미토콘드리아 기능 향상과 관련된 단백질인 PGC-1α과 Tfam을 증가시키고 산화적 스트레스의 방어 기전으로서 역할을 수행하는 항산화 효소인 Cu,Zn-SOD와 Mn-SOD를 활성화시키는데 긍정적인 역할을 수행한 것으로 나타났다. The purpose of this study is to identify the effects of exercise training [ET, 10~18 m/min (speed), 20~30 min (exercise duration)/a day for 5 day/wk, 6 wk) on PGC-1α, GLUT-1, Tfam, Cu,Zn-SOD and Mn-SOD proteins in brain of STZ-induced diabetic rats. The male Sprague-Dawley (SD) rats were single-injected intraperitoneally with 50㎎/㎏ of streptozotocin (STZ) to produce STZ-induced diabetic rats. Rats were divided into 3 experimental groups with 8 rats in each group, as follows: (1) non-STZ group (n=8), (2) STZ-CON group (n=8), (3) STZ-EXE group (n=8). The results of this study suggest that i) serum glucose level was significantly reduced in STZ-EXE group compared with STZ-CON group (p<0.05), ii) PGC-1α (p<0.001), mtPGC-1α (p<0.001), GLUT-1 (p<0.001), and mtTfam (p<0.001) proteins in brain of STZ-induced diabetic rats were significantly increased in STZ-EXE group compared with STZ-CON group, iii) Cu,Zn-SOD (p<0.001) and Mn-SOD (p<0.01) proteins in the STZ-induced diabetic rats were significantly increased in STZ-EXE group compared with STZ-CON group. In conclusion, the findings of the present study reveal that treadmill exercise training increases brain GLUT-1 protein level possibly through up-regulation of PGC-1α and Tfam proteins which represent key regulatory components of stimulation of brain mitochondrial biogenesis. In addition, treadmill exercise training may prevent oxidative stress by up-regulation of Cu,Zn-SOD and Mn-SOD proteins in the STZ-induced diabetic rats.
