Osteoarthritis (OA) is the most prevalent form of arthritis and a major cause of disability in people aged 65 and older. OA is not a single disease; rather, it is a group of overlapping yet distinct diseases with different etiologies but similar pathologic, morphologic, and clinical outcomes. OA occurs when the dynammic equilibrium between the breakdown and reapir of joint tissues is overwhelmed. Systemic and local biomechanical factors contribute to the development of the disease, with systemic factors also making the joint vulnerable and resulting in a greater impact of local joint factors. Systemic risk factors include ethnicity, gender, age, genetic factors, hormonal status, bone density, and nutritional factors. Local biomechanical factors include altered joint biomechanics, prior injuries, the effects of physical activities, sports participation, occupation, developmental abnormalities, and obesity. The normal joint is protected by biomechanical factors such as alignment and muscle strength, the lubrication provided by the synovial fluid, and the shock-absorbing function of bone and cartilage. When these functions are altered, changes occur at both the macroscopic and cellular levels, with derangements in any structure contributing to further joint destruction. 1) Further studies of both risk factor modification and cellular changes in OA will hopefully continue to enhance our understanding of this complex disease and lead to improved outcomes.

본 연구의 목적은 메가 이벤트의 수요에 영향을 미치는 요인들이 무엇인지를 규명하는데 있다. 이를 위해 계층분석적 의사결정(AHP: Analytic Hierarchy Process) 방법을 활용하여 메가 이벤트 관람수요의 영향요인에 대한 의사결정 계층구조모형을 설정하고, 각 요인의 우선순위를 파악하였다. 연구에 사용된 자료는 메가 이벤트 및 축제분야의 학계, 공공부문, 그리고 업계 전문가 40명을 대상으로 AHP 설문조사를 통하여 수집되었다. 또한, AHP 계층구조모형은 컨텐츠 및 프로그램, 가격요인, 홍보마케팅, 행사장 및 시설, 운영관리, 운영스태프 및 안내정보, 개최지역과의 협력을 포함한 총 7개의 대분류 영향요인과 26개의 하위요소로 구성되었다. AHP 분석결과, 메가 이벤트의 관람수요에 가장 크게 영향을 미치는 대분류 요인은 콘텐츠 및 프로그램으로 나타났으며, 그 다음으로 가격요인, 홍보마케팅, 행사장 및 시설, 운영관리, 개최지역과의 협력, 운영스태프 및 안내정보의 순으로 나타났다. 최종 가중치를 고려한 메가 이벤트의 관람수요 영향요인으로는 전시콘텐츠의 매력성이 26개 하위요소중 가장 중요한 것으로 나타났다. 본 연구결과를 바탕으로 메가 이벤트의 성공적 개최 및 운영을 위한 중요한 시사점을 제시하였다. The purpose of this study was to identify determinants of demand for mega-events. To this end the study proposed a hierarchical structure for assessing determinants of mega-event demand by applying Analytic Hierarchy Process(AHP). Data were collected from 40 experts in the area of mega-events and festivals. AHP hierarchical structure consisted of seven main determinants with 26 components, which included contents and programs, price factor, promotion and marketing activities, event site and facilities, event management, staff and information, and partnership with host community. The results of AHP analysis indicate that the most important determinant of mega-event was contents and programs, followed by price factor, promotion and marketing activities, event site and facilities, event management, partnership with host community, and staff and information in that order. Attractiveness of exhibition contents was the most critical determinant of mega-event demand among 26 components. The findings will provide policy makers and mega-event managers with practical implications in preparing for the planning and operation of successful mega-events.

The purpose of this study was to estimate the number of Korean casino visitors and their expenditures in the case of legalization of casinos in Japan. To this end onsite surveys were conducted to Korean outbound tourists at Gimpo airport and Incheon international airport. Major variables explaining willingness-to-visit casinos in Japan were estimated using a logit model, and the number of likely casino visitors and their expenditures were estimated based on estimated explanatory variables. The results of the logit model indicate that amount of casino expenditure, past experience in casino gaming, income, and age were important variables in explaining demand from Korean visitors to Japanese casinos. In other words, the more experience people had gambling in Korea and overseas, the more likely they would visit casinos in Japan. Also, people with higher income were more likely to visit casinos in Japan. In addition, younger gamblers and lower amount of casino expenditures increased the likelihood to visit Japanese casinos. When a minimum wager of 10,000 Korean won was presented to respondents, the number of annual visitors from Korea to casinos in Japan was estimated to be approximately 1.44 million and their casino expenditures of approximately 143.6 billion Korean won without the casino hold rate and 23.3 billion won with the hold rate would be spent by Koreans in Japanese casinos. When the minimum wager was increased by 1 million Korean won, the number of annual visitors was estimated to be approximately 1.04 million and their casino expenditures would be approximately 1037.8 billion won without the casino hold rate and 168.1 billion won with the hold rate.
