This study aims to evaluate a porous concrete using hwang-toh, blast furnace slag and blast furnace slag (BFS) cement instead of type I cement. The tests that were carried out to analysis the properties of porous hwang-toh BFS cement concrete included compressive strength, continuous void ratio, absorption rate, and pH value, repeated freezing and thawing test were conducted. Test results indicated that the performance in porous hwang-toh concrete are effective on the kaoline based binder materials. The pH value were shown in about 9.5 ~ 8.5. The compressive strength was increased and void ratio was decreased with increasing the kaoline based binder materials, respectively. The void ratio and compressive strength were in the range of about 21 ~ 30 %, 8 ~ 13 MPa, respectively. The increased in void ratio of more than 25 % is showed to reduce the resistance of repeated freezing and thawing. Also, the resistance of repeated freezing of thawing and the compressive strength of porous hwang-toh BFS cement concrete are independent with hwang-toh content and BFS cement amount. But, the void ratio was decreased with increasing the high volume hwang-toh contents (more than 15 %).

The physical, mechanical, water purification and temperature properties of fiber reinforced porous hwang-toh green roof concrete have been evaluated in this study. The effect of the depending on replacement ratio of blast furnace slag to cement was investigated such that the replacement ratio is varied to 0 % and 30 %. Also, the replacement ratios of hwang-toh were 0, 20 and 30 %. The polyvinyl alcohol fiber was used for the reinforcing fiber. A series of pH test, unit weight, void ratio, compressive strength, after purification and variation of temperature test have been performed to evaluate the performance, water purification effect and temperature properties of the fiber reinforced porous hwang-toh green roof concrete. The test results indicate that the physical and mechanical properties of fiber reinforced porous hwang-toh green roof concrete is affected by the replacement ratio of the blast furnace slag and hwang-toh contents. Results of purifying water showed that the water purification effect of porous hwang-toh green roof concrete is about 40 %. Also, the temperature properties test results indicate the green roof blocks using fiber reinforced porous hwang-toh green roof concrete have insulation and temperature reduction effect.

The purpose of this study was to investigate the effect of vascular compliance, blood glucose, and lactate concentration following submaximal exercise in older women for yoga practice during 8 weeks. Subjects for study was 10 females in 60~70 ages women. Blood samples were taken from finger in rest, immediately after submaximal exercise(HRmax 50~60%) and after 20 minutes recovery phase. All data was analyzed by t-test and ANOVA with repeated measures of SPSS, accepting level for all significances was above α = 0.05. In conclusion, yoga practice has an influence on of significantly decreased blood pressure and significantly increased vascular compliance. Yoga practice has an influence on of decreased blood glucose level in rest and improvement removal blood lactate level in recovery phase after submaximal exercise. Therefore, this conclusion suggested that Hatha yoga practices during 8 weeks has associated with improved blood pressure and vascular compliance as well as increased fatigue recovery capacity for older women.

연구논문 : 정주형 생활유산에서의 지역주민 공정성 -지역주민과 관광객간 상호 인식을 중심으로-

황희정 ( Hee Jeong Hwang ),윤현호 ( Hyun Ho Yoon ) 대한관광경영학회 2012 觀光硏究 Vol.27 No.3

본 연구는 정주형 생활유산에서의 지역주민과 관광객간 상호 인식을 중심으로 공정성 문제를 분석하였다. 마을관광에서의 공정성 문제는 지역주민과 관광객의 관계를 동등한 관계로 인식하고 마을에서 발생하는 편익을 공정한 과정과 절차로 분배하는 차원에서 이해하는 것이 중요하다. 이에 본 연구에서는 정주형 생활유산인 양동마을을 대상으로 지역주민과 관광객간 상호 인식을 조사하고 이를 비교하여 지역주민과 관광객의 입장에서 지역주민 공정성 문제를 분석하였다. 분석결과, 지역주민과 관광객의 진술내용에서 관광활동 과정에서의 공정성, 관광편익 분배의 공정성 모두 확보되지 않은 상황이었으며 양동마을 관광이 지니고 있는 지역주민 공정성에 대하여서도 대부분의 지역주민과 관광객이 ``불공정``한 것으로 인식하고 있었다. 이러한 결과는 지역주민 공정성 제고를 위하여서는 각 마을이 지니고 있는 지역주민의 욕구에 대한 이해, 지역 및 지역주민의 특성에 대한 이해를 토대로 접근해야함에도 불구하고 아직까지 지역에 대한 경제적 혜택 부여를 강조하고, 관광객의 ``책임``을 강조하는 상황에서 지역주민 공정성 문제가 인식되고 있다는 것을 의미한다. 따라서 지역주민 공정성 제고를 위하여서는 각 마을이 지니고 있는 지역주민의 욕구에 대한 이해, 지역 및 지역주민의 특성에 대한 이해를 토대로 접근해야 한다. 그리고 지역주민을 이해주체로서 인식하고 동등한 거래주체로서 지역주민에 대한 이해가 필요하다. 본 연구는 개념적 차원에서 논의되고 있는 지역주민 공정성에 대하여 양동마을이라는 정주형 생활유산에 적용하여 경험적으로 접근하였으며, 이를 통해 ``공정`` 개념을 국내 정주형 생활유산을 포함한 마을단위 관광에 적용하였다는데 학문적 의의를 갖는다. This study examined the fairness issue in the living heritage, the Yangdong village, focusing on the perspectives of the local residents on tourists and the perspective of tourists on the residents. In studying the fairness issue, in an area of the village tourism, it is important for the researchers to be equipped with a fair view on residents and tourists. Also, it is necessary for them to have a viewpoint that the conveniences arising from the village tourism should be equally distributed and shared by residents and tourists. In this sense, this study analyzes the perspectives of residents on tourists and the perspectives of tourists on residents in Yangdong village. Likewise, the research compares the residents` views with the tourists` views so as to scrutinize the fairness issue based on the different perspectives. According to the statements of the residents and the tourists in Yangdong village, they perceive the tour activities and the distribution of conveniences as unfair. The result reflects the fact that the prevailing living heritage tourism does not fully consider residents` needs, attributes, and characteristics; rather, it has built the notion of fairness by emphasizing the financial benefits from the industry and by imposing a great responsibility on tourists. Therefore, it is inevitable that new approach, taking into account the residents` needs, desires, attributes, and characteristics, should be embraced. In addition, this study suggests that we need to recognize the residents as participants who will share not only the awareness of the living heritage but the fair trade. This study takes an empirical approach by mainly dealing with ``the Yangdong village`` where the living heritage has been established. At this point, this study is differentiated from others that only incorporate conceptual and theoretical discussions. In addition, this study is likely to make a great contribution to the field of tourism because it applies the concept of the ``fairness`` into the village tourism including the living heritage.

해양생태관광 제약요인 분석

황희정(Hwang, Hee-Jeong),최영희(Choi, Young-Hee) 한양대학교 관광연구소 2016 觀光硏究論叢 Vol.28 No.1

해양관광을 활성화하기 위한 정책적 노력이 지속되고 있음에도 불구하고, 여전히 국내에서는 해양관광이 정착되지 못하고 있다. 해양보호구역에 대한 생태관광 역시 일부 해양보호구역에 한하여 활발하게 이루어지고 있는 것이 현실이다. 즉, 해양생태관광에 대한 요구가 기 형성되어 있음에도, 실제 해양생태관광 참여행동으로 연결되고 있지 못하다. 이러한 맥락에서 본 연구는 해양생태관광 태도와 행동의도에 영향을 미치는 해양생태관광 제약요인을 분석하는 데 목적이 있다. 분석 결과, 내재적 제약은 태도와 행동의도에 부의 영향을 미치며, 구조적 제약은 태도에 부의 영향을 미치는 것으로 분석되었다. 즉, 내재적 제약과 구조적 제약은 태도를 매개하여 직간접적으로 행동의도에 영향을 미치는 것으로 분석되었다. 이러한 결과를 토대로 볼 때, 관광객의 요구한 해양생태관광 프로그램 다양화 등을 통하여 내재적 제약을 제거하고, 해양생태관광에 대한 인지도 제고, 관광시설, 교통 등의 구조적 제약을 제거하기 위한 정책적 노력이 시급한 시점이다. Although there have a great deal of policy efforts to invigorate a marine tourism, it has not successfully established as a part of tour products yet in Korea. An eco-tourism within a marine sanctuary has been also restricted to very partial areas. There have been enormous needs for the marine eco-tourism, however no participations or no positive efforts have supported the needs. In the light of this perspective, this study has been aiming at analyzing what factors have affected the attitudes and the behavioral intentions in terms of the marine eco-tourism in Korea. The analysis shows that the intrinsic constrains negatively affect the attitudes and the behavioral intentions while the structural constrains is unhelpfully related to the attitudes. Both the intrinsic constrains and the structural constraints combined with the attitudes have a negative influence on the intention of actions. This result calls for prompt endeavors that include: 1) the elimination of the intrinsic constrains, by diversifying the marine eco-tourism based on travelers’ needs; 2) the political efforts for eradicating the structural constraints that include prevailing travelers’ unawareness, old tour facilities, and inconvenient transportations.
