The wetland ecosystem has a key role in climate change and can capture and store carbon long-term as blue carbon. Currently, the Republic of Korea and People's Republic of China are preparing for the UNESCO World Natural Heritage Phase II inscription, and cross-border cooperation among the two Koreas and the People's Republic of China is expected in term of the coastal wetland in the Yellow Sea region. However, there is a lack of research on the importance of coastal wetland in the Yellow Sea region for migratory bird habitats, roosting sites, feeding grounds, and stop-over sites. Thus, this study focused on the coastal wetland of the Yellow Sea region, including the southwestern coastal wetlands in the Republic of Korea, the Yancheng National Nature Reserve in the People's Republic of China designated as UNESCO World Natural Heritage, and the Mundok Migratory Bird Reserve in the Democratic People's Republic of Korea, which is listed on the Tentative List. The cooperation for ecosystem conservation between the two Koreas and China was analyzed. The importance of coastal wetlands in the Yellow Sea region as habitats for migratory birds, roosting sites, feeding grounds, and stop-over sites, significant characteristics of Yellow Sea coastal wetlands, and conditions for cooperation among three countries, were analyzed. The direction of ecosystem conservation cooperation for coastal wetlands in the Yellow Sea region in this study will be developed into Pan-Yellow Sea conservation.

중국에서는 관광, 휴식, 체험교육의 목적으로 농촌지역의 놀이농원이 증가하고 있다. 특히 농촌지역 수변공간의 놀이공원에 대한 이용의 증가는 수변공간에 대한 경관 및 단지 설계가 중요한 요소로 작용하고 있다. 이 연구에서는 산동성 등주시의 수변놀이농원의 이용자 1194명을 대상으로 설문지와 관찰 등의 연구방법을 통하여 이용 행태와 요구를 분석하였다. 이용자들은 연령대에 따라 다른 이용행태 및 요구를 보이고 있다. 먼저 이용행태에서 20대 이하는 흥미와 동적인 놀이의 이용행태를 선호하며, 연령대가 증가함에 따라 덜 동적인 이용행태를 선호하였다. 또한 모든 이용자들은 새롭고, 흥미롭고, 편안한 이용시설에 대한 요구가 높았다. 경관요소에 대한 평가에서 20대와 41살 이상의 집단간에 유의미한 차이를 보이고 있으며, 20~40살 집단간에는 유의미한 차이가 없었다. 20대의 이용자들은 시설이용에서 안전성과 레크리에이션기능에 대한 요구가 높았고, 41살 이상의 이용자들은 휴식시설과 공간의 확대를 요구하였다. 또한 이용자들의 대부분이 휴식시설에 대한 요구에서 그늘, 편안함, 양적인 차원에서 시설확대 및 보완의 요구가 높았다. 따라서 농촌관광에서 여가공간의 이용하는데 있어서 방문객의 태도와 만족도에 관한 연구들은 인본주의에 바탕을 둔 편의시설의 확대와 질적 개선이 요구되고 있으며, 이러한 결과를 토대로 최근에 증가하고 있는 중국인의 한국관광 및 방문에 대비하여 중국인의 관광시설선호와 이용만족 증가를 위한 실증적인 자료수집과 대안모색이 필요하다.

In this study, an LED emotional lighting algorithm optimized to the situation was implemented using fuzzy inference for users in exercise and resting situations in indoor environment. The fuzzy theory was used instead of the conventional simple color temperature control in order to control the colors and color temperatures of LED light sources in line with user environment under complex conditions. An LED emotional lighting system based on fuzzy theory was designed through a combination of colors according to the color and temperature of emotional language based on the user behavior. As a result, the color and color temperature can give a good effect on user's emotions for an emotional lighting that is effective for resting and exercise.

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 research was conducted to investigate the group and individual behavioral patterns of thoroughbred mares which are important for raising race-horses, in paddoks (pregnant) and pastures (nursing). In a group of nursing mare, eating 62%, standing resting 31%, drinking 3%, lying resting 1%, walking 1% and nursing 2% were observed, although no running was observed. Average time spent on individual behavior of mares (3 heads) was eating 295 min (55%), standing resting 193 min (36%), walking 18 min, drinking 18 min (3%), nursing 13 min (2%), lying resting 6 min (1%). Average 11 times of grooming, 2 times of urinating, and 1 time of feces were observed for mare in pasture. 48% of standing resting, 44% of eating, 2% of lying resting, 4% of walking, and 2% of drinking were revealed for pregnant mares in paddock. Average individual behavioral pattern of pregnant mares (3 heads) was 52% of eating, 40% of standing, 6% of walking, and 2% of drinking. Average 15 times of grooming, 1 time of urinating, 3 times of feces, 1 time of fighting, and 2 times of rolling were observed for pregnant mares in paddock. For moving patterns, pregnant mares were inclined to concentrate on where the nearby paddok is close to.

The purpose of this study is to analyze the difference between local residents and tourist groups in the relationship between the motivation for visiting and the satisfaction of Chung Nam Dae which is the leading tourist attraction in the Chungbuk region. We obtained 200 validated samples each of the local residents in Chungcheongbuk-do Province and the tourists from outside of Chungcheongbuk-do Province with experience of visiting Cheongnamdae through the survey using the questionnaire organized through literature research. The analysis result showed that the relationship between motivation and satisfaction varied depending on the overall sample, local residents, and tourist and that the natural relaxation and convenience had a positive impact on satisfaction in all groups. There was a difference in the influence between motivation and satisfaction between the two groups. Four motivational factors, including natural relaxation, convenience, historicity, and relationship had the significant influence on satisfaction for the local residents while two motivational factors, including natural relaxation and convenience, had the significant influence on satisfaction for the tourists. Based on the results of the study, we presented the theoretical and practical implications and suggested follow-up studies.

This study set out to investigate the effects of the same amount of resting(30 minutes) after $VO_2max$ 20%, 40%, and 60% exercise on the variation of cortisol and catecholamine, serum stress hormones. The research efforts led to the following conclusions: First, there were no significant differences in serum cortisol concentration between the $VO_2max$ 20% group and the $VO_2max$ 40% group, but there were some significant differences in the significance level of p=.002 in the $VO_2max$ 60% group. Second, there were no significant differences in serum catecholamine concentration between the $VO_2max$ 20% group and the $VO_2max$ 40% group, but there were some significant differences in the significance level of p=.001 in the $VO_2max$ 60% group. Third, no significant differences were found in the changing rates of serum cortisol concentration between right after exercise and during break among different levels of exercise intensity according to measuring time. Fourth, there were significant differences in the changing rates of serum catecholamine concentration in the significance level of p=.000 right after exercise and in the significance level of p=.034 during break In short, there were significant differences only in the $VO_2max$ 60% group according to exercise intensity when the different groups took the same amount of break after exercise. The $VO_2max$ 60% group was also the only group that showed significant differences in the changing rates of cortisol and catecholamine. In conclusion, taking a break after exercise can generate huge effects only when the exercise intensity level is moderate or higher. That is, taking a break will have no significant effects when the exercise intensity level is lower than moderate.

탄천은 경기도 용인시와 성남시를 지나 한강과 만나는 지천이다. 21세기의 탄천은 도시의 중앙부를 흐르며 도시인의 휴식공간으로 자리매김하고 있다. 한때 오염된 강으로 전락할 수도 있었지만 맑은 모습을 되찾게 된 것은 이 지역 사람들의 모임인 '분당환경시민의 모임'이 있었기 때문이다.
