국민관광객과 방한 외래관광객의 증가(문체부, 2012)로 도서와 해안지역에 대한 관광수요가 확산됨에 따라 중앙정부와 지방정부는 등대(예 : 영도등대, 간절곶등대, 울기등대, 거문도등대)를 중심으로 국민생활속의 해양관광공간, 해양레저스포츠공간, 어촌체험공간, 유통관광중심의 어항개발 및 크루즈관광활성화를 위하여 노력하고 있다. 새로움을 추구하는 관광객의 욕구가 증가하면서 틈새관광(niche tourism)의한 형태로 도서 관광(small island tourism)이 주목되고 있다(김영준, 2011). 내륙 중심의 관광에서 해양 관광으로 관심이 변화 확산되면서 친수공간시설에 대한 관광수요의 증가가 예상된다(이한석, 심미숙, 2009). 이와 같은 현실에서 도서에 위치하고 있는 등대자원을 활용하여 관광객의 욕구를 충족시킬 수 있는 등대관광활성화가 기대된다. 등대가 전통적인 기능과 역할에 충실한 항로표지로서 뿐만 아니라 공공서비스장소로서 해양문화를 향유할 수 있는 체험의 장을 제공하고 건축문화유산으로서의 역사성과 등대 고유의 기능에 대한 관광객의 흥미와 욕구를 잘 접목시켜 해양관광자원으로서의 가치를 극대화할 수 있을 것이다.

The aim of the present study was to investigate the effects of swimming exercise on growth-related telomere length and expression of TRF 2 in different tissues of SD rats. The telomere lengths of all the tissues analyzed were longer in the standard group than either in aged-control group or in two aged-exercise groups, suggesting growth-induced attrition of telomere lengths. On the other hand, it was also found that swimming exercise could attenuate this growth-related telomere attrition in the heart tissue of the long-term group only, with no significant attenuating effects of aerobic exercise on either liver telomere length or soleus muscle telomere length. Also, in the heart, TRF 2 expression was significantly lower in control group compare to standard group. But, there was significantly higher in long term exercise group compare to control group. There was positive correlation between telomere length and expression of TRF 2 in heart tissue. This study implies that the swimming exercise performed for longer periods of time can contribute to growth process of heart by regulation of telomere length and TRF 2 expression. In the growth process, the regular swimming exercise will provide a meaningful advantage for various physiological processes.

With the development of tangible interface in recent years, the interest in interactive exercise games to improve health-related physical fitness has been increased. We believe that this kind of serious game should provide not only motion sensing of the action required to play sports but also a specific effectiveness of exercise. This paper will show how a serious exercise game affects theirs heart rate and preference. For the experiments, we used an exercise game named GalaxyBike for aerobics exercise which is developed by the Interaction Media Research Center of Hoseo University. In the experiments, players' heart rate was measured during the warming-up, exercise and cooling-down periods by a wireless heart-rate measuring instrument. After they played the exercise game, a survey was conducted to see how they like this serious exercise game. The findings of the study suggest that the serious exercise game providing both video game and exercise would make a contribution to the improvement of health-related physical fitness since it serves to increase the heart rate and motivation.

Economic impact analyses have not been widely conducted in archives. This article reports on a two parallel surveys in the US and Canada to assess the economic impact of government archives (state, provincial, territorial, county, and municipal). The surveys utilize indirect measures of economic impact. Responses from 2,534 people in 66 archives were analyzed. Findings indicate that archives were the primary reason that respondents visited an area and that visitors exhibit specific patterns of visiting the archives in conjunction with other cultural organizations in an area. Furthermore, while many respondents used local eateries, fewer rented lodgings or spent money on theater or sporting events. As a result, the archives participating in this survey did have a modest impact on local economies. The article concludes by discussing three major questions about the evaluation of the economic impact of archives which were raised by the findings: 1) Are indirect measures the most appropriate means of assessing economic impact in archives or should archives employ direct measures as used by public libraries? 2) How should government archives formulate their value proposition and should those value propositions focus on other aspects of archives' impact, such as the social impact, to demonstrate archives' important role in society? and 3) Since visitors exhibited distinct visitation patterns, should archives work more with these other aligned organizations and work on larger forms of collective impact that benefit the entire cultural heritage sector in an area?

The purpose of this study was to propose an effective field test for assessing the cardiovascular endurance of soccer players by comparing the shuttle run test and the Yo-Yo intermittent recovery test (Yo-Yo test), which are representative of the aerobic exercise performance test, with the VO2max and other sprint tests. The shuttle run test requires the subject to run continuously without a break interval, while the Yo-Yo test has a break interval, so that they run with the recovery period. Therefore, the Yo-Yo test can be used as an effective field test for evaluating the cardiopulmonary function considering the characteristics of the soccer players of intermittent training.

This study was conducted from November 25 to December 4, 2019, to unmask differences in physical fitness based on the weight class of high school Ssirum elite-players. A total of 28 high school Ssirum elite-players were compared and analyzed by measuring physical factors (muscle strength/power, agility, anaerobic power, aerobic ability, flexibility, and isokinetic muscle function) by weight class. Data were analyzed using SPSS ver. 23.0. One-way ANOVA was used for comparison between groups. There was no difference by weight class in terms of grip strength, sit-ups, sergeant jump, long jump, flexibility, side step, and reaction time. Evaluation of back muscle strength revealed that the group with more than 100 kg had greater strength than lower weight categories, whereas it was lower in the sit-ups, 20 m shuttle run and the relative values anaerobic power. Considering isokinetic muscle function, no difference was observed between the groups of back muscle strength and knee joint. The results of this study indicate that amongst the high school Ssirum elite-players, there is no difference in muscle power, flexibility, agility, and anaerobic average power per body weight, isokinetic trunk strength, and knee flexion strength, when evaluated according to weight class.

Exercise increases the expression and interaction of major neurotrophic factors such as brain-derived neurotrophic factor (BDNF), insulin-like growth factor-1 (IGF-1), and vascular endothelial growth factor (VEGF) at both central and peripheral tissues, which contributes to improved brain and neural plasticity and cognitive function. Previous findings have been to understand the effect of light or moderate intensity aerobic exercise on neurotrophic factors and cognitive function, not that of high intensity aerobic exercise. However, recent findings suggest that high intensity interval training is a safe, less time-consuming, efficient way to improve cardiorespiratory fitness and weight control, thus American College of Sport Medicine (ACSM)’s guidelines for exercise prescription for various adult populations also recommend the application of high intensity interval training to promote their overall health. High intensity interval training also enhances the expression of BDNF, IGF-1, and VEGF at the brain and peripheral tissues, which improves cognitive function. Increased frequency of intermittent hypoxia and increased usage of lactate as a supplementary metabolic resource at the brain and neural components are considered a putative physiological mechanism by which high intensity interval training improves neurotrophic factors and cognitive function. Therefore, future studies are required to understand how increased hypoxia and lactate usage leads to the improvement of neurotrophic factors and what the related biological mechanisms are. In addition, by comparing with the iso-caloric moderate continuous exercise, the superiority of high intensity interval training on the expression of neurotrophic factors and cognitive function should be demonstrated by associated future studies.
