The traditional temples located in national parks have various functions, such as religious practice, tourist destination, and conservation for cultural and natural resources. One functions have implicit monetary values in terms of public benefits. The purpose of this study was to estimate both use and non-use conservation values for two traditional temples, Sinheungsa and Haeinsa, using the contingent valuation method. In the study, both single-bounded and double-bounded dichotomous choice methods were used in an application of Turnbull distribution-free model. A total of 659 visitors were interviewed, 350 in Sinheungsa and 309 in Haeinsa. The mean WTP (willingness to pay) for Sinheungsa using single-bounded method was 4,040 Won for the use value, 6,157 Won for the cultural conservation value, and 5,624 Won for the natural conservation value. The mean WTP for Haeinsa using single-bounded method was 6,463 Won for the use value, 8,769 Won for the cultural conservation value, and 8,013 Won for the natural conservation value. The total economic value of each temple accounted for 50% (Sinheungsa) and 80% (Haeinsa) of the total economic value of the associated national park. It was also found that the single-bounded method was more conservative than the double-bounded method in terms of value estimation. The WTP was highest for the cultural conservation value and lowest for the use values in both temples, with natural conservation values falling in the middle, which showed that people perceived traditional temples as the cultural heritage. Based on these results, it was suggested that traditional temples should be designated as an 'multiple heritage area' so that conservation can be used as the main criteria for various use programs.

Today, people are becoming more conscious regarding environmental-friendliness, and the society as a whole is becoming more aware of it. With such phenomenon, the purpose of this research is to examine how comfort and pleasantness of indoor environment influences when selecting a place for multi-cultural complex. To demonstrate the stated hypothesis, I have preceded the experiment by selecting the C multi-cultural complex of closed-type structure and T multi-cultural complex of open-type structure. The next step I took, in order to validate the public's awareness of environmental-friendliness, was conducting a survey. I then deducted a conclusion through comparison and analysis of experiment measures with survey result. As a result of the research, the experiment measures of each air, light, heat condition of the T multi-cultural complex of open-type structure had a higher measurement for the comfort and pleasantness than the C multi-cultural complex of closed-type structure. Moreover, after validating the consciousness of the public through the survey, they had a tendency preferring T multi-cultural complex of open-type structure over C multi-cultural complex of closed-type structure in terms of comfort and pleasantness. To summarize, it is proper to conclude that the criteria - comfort and pleasantness of indoor environment - has influenced significantly when it comes to selecting a multi-cultural complex through both the experiment and the survey result.

Purpose: The reconstruction of a soft tissue defect of the heel pad can be challenging. One vital issue is the restoration of the ability of the heel to bear the load of the body weight. Many surgeons prefer to use local flaps or free tissue transfer rather than a skin graft. In this study, we evaluated the criteria for choosing a proper flap for heel pad reconstruction. Methods: In this study, 23 cases of heel pad reconstruction were performed by using the flap technique. The etiologies of the heel defects included pressure sores, trauma, or wide excision of a malignant tumor. During the operation, the location, size and depth of the heel pad defect determined which flap was chosen. When the defect size was relatively small and the defect depth was limited to the subcutaneous layer, a local flap was used. A free flap was selected when the defect was so large and deep that almost entire heel pad had to be replaced. Results: There was only one complication of poor graft acceptance, involving partial flap necrosis. This patient experienced complete recovery after debridement of the necrotic tissue and a split thickness skin graft. None of the other transferred tissues had complications. During the follow-up period, the patients were reported satisfactory with both aesthetic and functional results. Conclusion: The heel pad reconstructive method is determined by the size and soft-tissue requirements of the defect. The proper choice of the donor flap allows to achieve satisfactory surgical outcomes in aesthetic and functional viewpoints with fewer complications.

Objectives: Radiotherapy is an effective treatment in the initial management of T1 glottic carcinoma, but local recurrent or residual tumor growth is found in approximately 10% of the patients. Even in recurrence or residual tumor, in highly selected cases, conservation surgery with preservation of a portion of the larynx is feasible. So we investigated the efficacy of salvage vertical partial laryngectomy for recurrent glottic carcinoma after irradiation. Material and Methods: Retrospectively we reviewed a consecutive series of 10 patients treated by conservative vertical partial laryngectomy of the larynx for radiation-failure, recurrent T1 glottic squamous cell carcinoma treated at Severance Hospital from 1994 to 2002. Results: Local recurrence developed in 4 patients (40%). Two patient was salvaged by further totallaryngectomy. Successful salvage was achieved finally in 8 (80%) of the 10 patients. There was no operative mortality. Postoperative perichondritis was developed in two patients. One was resolved by conservative treatment, but the other has underwent the total laryngectomy. Conclusion: A vertical partial laryngectomy in case of recurrent glottic carcinoma after a course of irridation should be the therapy of choice when stringent criteria are observed.

터널화재는 국제적인 관심사이며, 매년 중대 터널화재는 발생하고 있다. 교통밀도가 증가하면서 장대터널은 물론, 더 많은 수의 터널이 건설되고 있어서, 앞으로 터널화재의 잠재위험성이 더 나빠질 수 있으므로 더욱더 심각한 문제이다. 도로터널 화재발생시 소방대원이 효과적인 소방활동 전략을 수립하도록 하는 것이 본 연구의 궁극적 목적이다. 과거 화재 사례로부터 어떠한 사고가 발생하였고, 어떠한 소방활동이 행해졌는지 알아보기 위하여 국내외 73건의 터널화재사고사례를 조사하여 4가지 사고유형으로 분류하였다. 소방활동의 전략수립을 위해 개입시간과 열방출율의 관계로 6가지 화재시나리오 곡선을 도출하였다. 이것은 두 가지 기준 즉, 반응한계와 최대 도착시간에 따라 소방활동의 전략을 수비적, 공격적 전략 중 선택할 수 있도록 하였다. 도로터널 분류 모델은 각 소방기관이 관할 터널의 화재 위험 정도를 화재 진압의 관점에서 평가하고 예방조치를 수립하는데 사용될 수 있다.

Purpose: To compare clinical and radiographic outcomes of between two and three Kirschner wire(K-wire) intramedullary fixation for fractures in the neck of the metacarpal bone. Methods: A single institutional retrospective review identified 28 cases of metacarpal fractures between March 2010 and August 2014. Each of the cases met the inclusion criteria for closed, extra-articular fractures of the neck of the metacarpal bone. The patient groups were divided by the number of K-wire. Outcomes were compared for range of motion of the metacarpophalangeal joint, radiographic parameters, and period until union. Results: The fractures were treated with either 2 Kirschner wire fixation (n=10) or 3 Kirschner wire fixation (n=18). The active range of motion of metacarpophalangeal joint and radiographic result showed no statistically significant difference between the two groups. The mean union period was 5.9 weeks. However, four cases suffered distal head perforation in 2 K-wire fixation group and one case in 3 K-wire fixation group. Conclusion: Multiple retrograde intramedullary Kirschner wire fixation is a good treatment of choice for fractures in the neck of the metacarpal bone. To prevent metacarpal head perforation, it is preferred to use three K-wires than two K-wires.

Objectives: The purpose of this study is to demonstrate empirically through a specialist AHP analysis what factors should be more important in the development of the public health care system. In addition, we will use Analytic Hierarchy Process (AHP) method for experts to achieve research purpose. Methods: The data analysis method of this study is as follows. First, we set up three metrics in order to measure the relative importance between the factors to be improved for the development of the public health care system and each of the sub-factors. A total of nine measurements (items) were set by combining the three measurement criteria for each measurement index. Second, the relative importance and priority analysis use the AHP analysis. Third, the subjects of this study were 15 experts in the field of public health care. The statistical processing was performed using the Expert Choice 2000 statistical program. Results: In order to development of the public health care system, experts ranked the most important as improvement in the systematic aspect of public health care (56%) as the first priority. Next, the relative importance analysis of the measurement items considering the multiple-weights of the sub-factors is as follows. The strengthen institutional improvement (revitalization of secondary public function hospital) was the number one, strengthen cooperation between agencies was the second, and Re-establishing the role of local public health care system was the third place. Conclusions: Considering the relative importance, factors that are considered to be important in the first place may not be improved as the best policy alternative due to limitations in spatial, temporal, financial, and institutional aspects. In this case, we suggest that we should choose the best policy alternative by using prioritization considering relative weights.

This study is to excavate superior fishing communities by applying the Ostrom (1990)'s principles of sustainable and successful use of common goods. Ostrom(1990)'s principles are (1) clearly defined boundaries (2) congruence between appropriation and provision rules and local conditions, (3) collective choice arrangements (4) monitoring (5) graduated sanctions (6) conflict-resolution mechanism (7) recognition of rights to organize by external government authorities (8) nested enterprises. The survey was carried out under the individual interview method of 15 fishing village members in 32 fishing communities with the government's fishery environment improvement and fishery creation projects. The total effective samples are 477. These data were analyzed. The analysis result shows that 24 fishing villages are selected among the 32 fishing communities in the samples, including Nanji, Sanghwang, Songseok, Sinshido, Jukyo, Jinsan, Changli, Pado, Beopsan, Rahyang, Palbong, Woongdo, Daehwang, Sapsi, Chido, Jinri, Daeri, Songgak, Joongwang, Ojii, Doripo, Doseong, Mongsan 1ri and Songnim as superior fishing villages. The results of this study have limitation that may vary depending on the rigor of the criteria in the process of deriving good fishing communities. Despite this limitation, this study has expanded existing research focused on validating the theoretical applicability of the framework through case analysis of specific fishing communities to objectively and quantitatively to many fishing communities. The results of this study are expected to contribute to the creation of conditions in which fishermen can continue to manage their fishing grounds and stand on their own feet by presenting the framework and principles for developing desirable fishing village models for the continued use of mudflat shells grounds as the common goods.
