정호원 ( Ho Won Jeong ) 한국스포츠산업경영학회 2010 한국스포츠산업경영학회지 Vol.15 No.5

최근 한국프로야구의 중요한 경제 주체이자 협상단체로서 인정받으려는 프로야구선수협의회(선수협)는 노조설립을 위한 본격적인 활동을 전개하고 있다. 이러한 과정에서 선수협은 한국야구위원회(KBO)와의 적지 않은 마찰을 불러일으키고 있다. 이 러한 시점에서 두 단체 간의 갈등이 팬들로 하여금 KBO에 대한 사회적 책임에 대한 인식과 이미지에 어떠한 영향을 미치는 지를 분석하는 일은 의미있다 하겠다. 따라서 본 연구의 목적은 첫째, 선수노조 설립 추친에 따른 선수협과 KBO간의 갈등에 대한 프로야구 팬들의 인식이 KBO의 사회적 책임활동 인식에 어떠한 영향을 미치는가, 둘째, KBO의 사회적 책임활동 인식은 KBO의 이미지에 어떠한 영향을 미치는가를 규명하는데 있다. 연구자는 프로야구에 관심이 있는 대학생 334명에게 설문조사 를 실시하였으며, 앞서 제시한 연구문제를 검증하기 위해 구조방정식모형분석 방법을 사용하였다. 우선, 본 연구를 통해 KBO 의 사회적 책임을 법적.윤리적 책임, 팬보호 책임, 자선적 책임이라는 3가지 차원으로 도출할 수 있었다. 이에 기초한 연구결 과는 다음과 같다. 갈등에 대한 KBO의 대응이 부적절하다고 인식하는 팬들은 KBO가 법적.윤리적 책임, 팬보호 책임, 자선 적 책임에 소홀하다고 여기는 것으로 나타났다. 그리고 KBO가 법적.윤리적 책임, 팬보호 책임, 자선적 책임에 소홀하다고 여기는 팬들은 KBO에 대해 부정적 이미지를 가지고 있는 것으로 나타났다. 이상의 결과는 갈등에 대한 팬들의 인식이 KBO 의 사회적 책임활동 수행에 대한 인식에 영향을 미치고, 더나아가 KBO의 이미지에까지 영향을 미치는 것으로 나타났다. 결론 적으로 갈등에 대한 팬들의 인식은 KBO의 사회적 책임활동이라는 매개변인을 통해 KBO의 이미지를 간접적인 영향을 미치는인과관계가 형성됨을 알 수 있었다. This study was designed to analyze (1)the impacts of fan``s perceptions of conflict between Players`` Association and KBO(Korean Baseball Association on perceptions of KBO``s social responsibilities and (2)the impact of perceptions of KBO``s social responsibilities on KBO``s images. For this study, the author defined components of KBO‘s social responsibility as legal & Ethical, philanthropic and fan-protection responsibilities. This conceptualization was confirmed in the survey with 344 fans of Korean Professional Baseball. The result revealed that fans who have negative perception of the conflict tend to give unfavorable evaluations on KBO``s social responsibilities. Furthermore, negative perceptions of KBO``s social responsibilities tend to produce negative images of KBO. In sum, perception of the conflict indirectly influcences KBO``s image through KBO``s social responsibilities.

정호원(Jeong, Ho-won),이석호(Lee, Suk-ho) 한국경호경비학회 2020 시큐리티연구 Vol.- No.62

현재 국가주요시설 중 하나인 원자력발전소에서 근무하고 있는 특수경비원은 원자력시설 및 핵물질에 대한 위협으로부터 이를 안전하게 보호하기 위한 인적 방호의 역할을 수행하고 있다. 본 연구에서는 특수경비원의 임무완수에 필수적인 체력관리를 위한 체력훈련 프로그램을 개발하고자 하였다. 개발된 체력훈련 프로그램은 현재 근무 중인 특수경비원이 정호원, 최지웅(2019)이 제시한 원자력발전소 특수경비원 체력검정에 대비할 수 있도록 고안되었다. 연구진은 문헌분석, 연구진 회의, 전문가 회의 및 사전테스트를 진행하였으며, 이러한 과정을 거쳐 6주, 주 3회, 회 90분의 체력훈련 프로그램을 개발하였다. 한편 개발된 체력훈련 프로그램의 효과를 검증하기 위해 29명의 피험자(통제집단 15명, 운동집단 14명)를 대상으로 실험을 실시하였다. 구체적으로 운동집단을 대상으로 6주에 걸친 체력훈련 프로그램을 수행하였으며, 실험 전･후 피험자 전원을 대상으로 특수경비원 체력검정을 실시하였다. 실험 결과 개발된 체력훈련 프로그램의 수행이 특수경비원의 체력검정종목인 20m왕복오래달리기, 철봉에매달려무릎팔꿈치닿기, 20m중량왕복달리기, 메디슨볼뒤로던지기의 능력향상에 유의미한 효과가 있는 것으로 나타났다. 최근까지 특수한 환경 속에서 국민안전이라는 중대한 임무를 수행하고 있는 원자력발전소 특수경비원의 체력관리 및 감독 소홀에 대한 문제점들이 지적되고 있는 바, 본 연구가 제시한 체력관리 프로그램이 특수경비원들의 체력 유지･관리를 위한 실질적 대안이 되기를 기대한다. Special security guards working at nuclear power plants, one of the country s major facilities, serve as human protection to safeguard from threats to nuclear facilities and nuclear materials. The purpose of this study was to develop a physical fitness program for fitness management that is essential for the completion of missions of special guards. This program was designed to prepare the physical fitness test proposed by Jeong et al. (2019). Researchers conducted literature analysis, research meetings, expert meetings and pretests, and developed a 90-minute physical fitness program for 6 weeks, 3 times a week. In order to verify the effectiveness of the developed physical fitness program, the experiment was conducted on 29 subjects(control group: 15, exercise group:14). Specifically, a six-week physical fitness program was conducted for exercise groups, and the fitness test for a special security guard was conducted for all subjects before and after the experiment. As a result, it was found that the physical fitness program was effective in improving the performance of 20m shuttle run, leg tuck, 20m sprint & carry, and medicine ball back throw. Until recently, problems of neglecting fitness management of security guards have been pointed out. It is expected that the physical fitness program proposed by this study will be a practical alternative for security guards’ fitness management.

The main objective of this study is to investigate the order effect in the scale of spectators' motivation. Authors made two types of questionnaires: For Type Ⅰ, questions estimating same factor are arranged consecutively. For type Ⅱ, questions are arranged randomly. A total of 334 Respondents received one of two questionnaires and completed it. The results showed that correlations among questions estimating same factor in Type Ⅰ were higher than those among questions estimating same factor in Type Ⅱ. Futhermore, the results of factor analysis revealed that construct validity and discriminant validity of Type Ⅰ were higher than those of Type Ⅱ. In sum, to arrange questions estimating same factor consecutively produces consistent responses. But to rotate question order results in increased inconsistency among responses.

정호원(Jeong, Ho-Won),이혁기(Lee, Hyuck-Gi) 한국사회체육학회 2017 한국사회체육학회지 Vol.0 No.68

In this study, we focused on A family badminton event in the context of storytelling properties. Specifically, we applied the IPA (Importance-Performance Analysis) technique suggested by Marta & James (1977) to find ways to vitalize the family badminton event. The family badminton event, which is a research subject, was organized by Korea Council of Sport for All, which has been held for the first time since 2003 and attracted about 1,000 people every year. A questionnaire was conducted for those who participated in the family badminton event and 314 questionnaires were obtained as valid samples. For the analysis of the importance and satisfaction of the 4Cs for the family badminton event, the corresponding t-test was conducted using the SPSS 18. 0 version program. The significance level was .05. The results obtained are as follows. First, the attributes that need to be maintained and managed in the current state includes tress relief, accessibility of the facility, size and sufficiency of the facility, participation procedures and regulations, financial support for hosting the event, compensation for game result and accident insurance for participating in the event. Second, the most important attributes that require improvement efforts are good use of leisure activities, communication among family members, communication between other families, communication with operators and managers of the event. Third, attributes that should not be taken into consideration ta the present time are attributes such as family bond formation, improvement of exercise performance, and promotion of event & construction of information infrastructure. Fourth, the attributes that are over emphasized at present are the family health promotion and the operation of event program.

토끼 단일 심근세포에서 대사억제시 Inward Rectifier$(I_{K1})$의 변화

정유정,호원경,엄융의,Chung, Yu-Jeong,Ho, Won-Kyung,Earm, Yung-E 대한약리학회 1997 The Korean Journal of Physiology & Pharmacology Vol.1 No.6

In the present study, we have investigated the effect of metabolic inhibition on the inward rectifier K current ($I_{K1}$). Using whole cell patch clamp technique we applied voltage ramp from +80 mV to -140 mV at a holding potential of -30 mV and recorded the whole cell current in single ventricular myocytes isolated from the rabbit heart. The current-voltage relationship showed N-shape (a large inward current and little outward current with a negative slope) which is a characteristic of $I_{K1}$. Application of 0.2 mM dinitrophenol (DNP, an uncoupler of oxidative phosphorylation as a tool for chemical hypoxia) to the bathing solution with the pipette solution containing 5 mM ATP, produced a gradual increase of outward current followed by a gradual decrease of inward current with little change in the reversal potential (-80 mV). The increase of outward current was reversed by glibenclamide ($10\;{\mu}M$), suggesting that it is caused by the activation of $K_{ATP}$. When DNP and glibenclamide were applied at the same time or glibenclamide was pretreated, DNP produced same degree of reduction in the magnitude of the inward current. These results show that metabolic inhibition induces not only the increase of $K_{ATP}$ channel but also the decrease of $I_{K1}$. Perfusing the cell with ATP-free pipette solution induced the changes very similar to those observed using DNP. Long exposure of DNP (30 min) or ATP-free pipette solution produced a marked decrease of both inward and outward current with a significant change in the reversal potential. Above results suggest that the decrease of $I_{K1}$ may contribute to the depolarisation of membrane potential during metabolic inhibition.

In general, femur fractures in the younger patient population are the result of high energy trauma, such as motorcycle accidents or traffic accidents. A 43-year-old healthy man presented with painful swelling of his right thigh. Plane radiographs showed short oblique fracture of the femur shaft with comminution. He had no medical history such as osteoporosis or any metabolic bone disorder. He was a healthy man with no smoking and no alcohol drinking, enjoying sports activity such as baseball and football. He was injured during defense time of a baseball game by rapid turning motion to catch a ball. We performed intramedullary interlocking nailing for the femur shaft fracture and the fracture was uneventually healed with no complication. To our knowledge, femur shaft fracture which occurred during playing baseball in a healthy middle-aged man has not been reported in our country. So we report this case with a review of the literature.
