In 1990's, the high-rise buildings have faced the need for the overall repair of the structure and function rather than the. partial repair. In order to remodel a existing office buildings to enhance their functions, basically, an objective evaluation on the current state and establishing the criteria or the evaluation should be preceded. However, the evaluation standards or models are not available yet. In this study, Analytic Hierarchy Process (AHP) and Multicriteria decision-making process were applied to evaluate the efficiency of remodeling for office buildings. Especially, this study was focused on functional and economical efficiency evaluation. Based on these points, we developed the evaluation system, and verified a validity of evaluation system through a case study.

경제성장과 소비수준의 질적 향상은 기존 제품품질에 집중하던 소비자의 가치관을 서비스 품질 중심으로 이동시켰다. 이에 따라 서비스를 제공하는 서비스 종업원이 기업의 이미지를 형성하는 마케팅 요소 중 하나로 인식되고 있으며, 종업원과 고객 간의 상호작용 품질이 소비자 행동에 중요한 역할을 하게 되었다. 그럼에도 불구하고 서비스 종업원의 성격특성이 소비자의 인식 및 구매 행동 변화에 어떠한 영향을 미치는지에 관한 연구는 미미한 실정이다. 따라서 본 연구는 서비스 접점에서 종업원의 성격특성이 소비자의 인식 및 구매행동에 어떤 영향을 미치는지 실증적으로 분석하였다. 연구결과, 서비스종업원의 성격특성이 각각 상호작용과 고객만족에 긍정적인 영향을 미치며, 상호작용은 고객만족과 고객충성도에 긍정적인 영향을 미치는 것으로 나타났다. 또한 고객만족은 고객충성도에 긍정적인 영향을 미치는 것으로 나타났다. 그리고 서비스 종업원의 성격특성은 상호작용과 고객만족을 부분적으로 매개하여 고객만족도에 유의한 영향을 미치는 것으로 나타났다. 본 연구를 통하여 서비스 접점에서 종업원의 성격특성이 고객 행동에 미치는 영향력을 실증적으로 확인함으로써 고객 충성도를 제고하기 위한 방향성을 제시하였다. Today s economic growth and the qualitative improvement of consumption are shifting consumer values from product quality to service quality, which raises awareness of the importance of employee services that accompany products. As a result, service employees who provide services are recognized as one of the marketing elements, leaving the interaction quality between the employee and the customer a major factor influencing consumer behavior. However, despite the importance, research on how the personality characteristics of service employees affect changes in consumer perception and purchasing behavior is insignificant. Thus, this study validated the impact of the characteristics of the employees’personality recognized by customers on interaction and customer satisfaction, the impact of interaction and customer satisfaction on customer loyalty, and the mediating effect of involvement in the relationship between them. The results have shown that the characteristics of service employees personality have a positive effect on interaction, customer satisfaction and customer loyalty. In addition, it could be seen that interaction and customer satisfaction had a mediating effect on customer loyalty. Based on the empirical research results, this study was able to discover the difference in the influence of each dimension of personality characteristics on customer behavior. In a practical point of view, this study has presented the virtues of service personnel that can positively influence the company s image and customer s behavior.

There are only 10 projects of the domestic greenhouse gas(GHG) emissions trading scheme in building sector (i.e., 1.5% of 652 registered projects) because the certified methodologies to reduce GHG emissions can not be applied to building sector. This study presents remodeling techniques to reduce GHG emissions in existing buildings. First of all, preconditions and related regulations were reviewed. And then, a pool of factors for GHG reduction are selected and evaluated with respect to factors for reducing energy consumption. This study also investigates the criteria and the decision making process for remodeling techniques to reduce GHG emissions. Finally, the remodeling techniques using the decision making process were grouped based on redundancy of each effect. If reducing methodologies for GHG offset program can be developed using the analyzed remodeling techniques in this study, registered projects in building sector would be increase.

운송부문은 전체 대기오염물질 배출의 큰 비중을 담당한다. 대기오염물질 배출을 획기적으로 죽이는 방법으로 전기차가 도입되었지만, 여전히 전기차 판매는 저조하고, 화석연료를 사용하는 기존의 자동차들에 비해 상당히 적은 수가 운행 중이다. 여러 선행연구가 전기차로의 전환의도를 연구했으나, 영향요인을 포괄적인 접근으로 도출하고 분석한 연구는 적다. 이러한 한계를 극복하기 위해 새로운 연구가 필요하다. 한국에서 수집한 데이터에 대한 AHP 분석 결과, 차원에 대하여 제품품질(40.9%), 정책 지원(27.3%), 시장 환경(18.1%), 소비의식(13.7%) 순으로 전기차로의 전환의도에 영향을 미치는 것으로 나타났으며, 요인의 경우 신뢰성과 내구성(13.7%), 구매 보조금(11.1%), 성능(10.1%)의 순으로 높은 영향을 미치는 것으로 나타났다. 중국의 경우 정책 지원(54.8%), 소비의식(33.1%), 제품 품질(7.4%), 시장 환경(4.7%) 순으로 영향정도가 나타났으며, 요인은 정부 규제(38.7%), 자원 절약(26.7%), 구매 보조금(7.8%) 순으로 높은 영향을 미치는 것으로 나타났다. 본 연구는 정책 결정을 위한 가이드 라인을 제시하는 한편, 자동차 제조업체의 전략 수립을 위한 기초 데이터를 제공하는데 의의가 있다. 또한, 전기차의 친환경성과 경제성에 중점을 둔 선행 연구와 달리 본 논문은 신뢰성과 내구성, 자원 절약 등의 새로운 영향요인을 제시 할 수 있었다. 마지막으로 문화적으로 구분되는 두 표본의 비교를 통해 본 연구는 수출의 상황에 대비한 지침을 제공할 수 있었다. The transportation sector is responsible for a large quantity of air pollutant emission. While electric vehicles are introduced as a method to dramatically reduce air pollutant emission, the sales of electric vehicles are relatively low compared to traditional vehicles running on fossil fuel. Past studies have analyzed the factors influencing the conversion intention of electric vehicles. However, they share the limitation of not being able to examine the subject in a comprehensive approach, bringing up the need for a new research. AHP analysis conducted on the data collected for Korea showed the relative effect of dimensions as product quality (40.9%), policy support (27.3%), market environment (18.1%), and consumption consciousness (13.7%). For the factors, reliability and durability (13.7%), purchase subsidies (11.1%), and performance (10.1%) showed an especially high effect on the conversion intention. For the case of China, results showed the relative effect of dimensions as policy support (54.8%), consumption consciousness (33.1%), product quality (7.4%), and market environment (4.7%). For the factors, governmental regulation(38.7%), Resource Saving(26.7%), and purchase subsidies(7.8%) showed an especially high effect compared to other factors. The study provides a guideline for policy making and the basis data for strategy establishment of automakers. Also, in contrast to former research that mainly concentrated on the eco-friendliness and economic aspect of electric vehicles, this paper was able to define the importance of reliability and durability, and resource saving as an influencing factor, providing a new direction for improvement. In addition, with the comparison of two culturally distinct groups, the study was able to provide a guideline for exporting situations.

본 연구는 2008년 2월부터 2013년 12월까지 월악산국립공원에 도입 방사된 암컷 산양 4개체의 행동 특성을 연구하기 위하여 연간 행동권, 계절별 행동권, 고도별 이용 특징을 연구하였다. 도입 방사된 암컷 산양의 연간 행동권은 MCP 95% 1.13±0.32km2, FK 95% 0.37±0.18km2, FK 50% 0.07±0.03km2로 분석 되었고(t=0.607, p>0.05), 계절별 행동권 및 고도 이용특성은 MCP 95%에서 여름(0.77±0.06km2), 가을(0.73±0.26km2)로 행동권이 크며, 봄(0.58±0.38km2), 겨울(0.47±0.25km2)에 행동권이 감소하여 여름과 겨울 행동권의 차이를 보였고(F=3.868, P<0.05), 계절별 고도 이용 특성은 봄 435m(28.4%), 여름 464m(26.7%), 가을 414m(28.8%), 겨울 393m(21.2%)로 여름에 높은 고도로 이동하며 겨울철 고도가 낮은 지역을 이용하는 것으로 분석 되었다(F=0.783, P>0.05). 본 연구에서 도입 방사된 암컷 산양 개체만 연구되어 전체적인 행동특성이라고 단정 할 수 없지만, 행동권, 계절별 행동권, 고도 분석 등으로 서식지 이용특성에서 유의미한 차이가 있는 것으로 분석 되었다. This study was executed in Woraksan National Park from Febuary, 2008 to December, 2013 in order to study the behavioral characteristics of introduced four female gorals using annual home range, seasonal home range, and elevation use characteristics. Annual home range of reintroduced female gorals were 1.13±0.32km2 of MCP 95%, 0.37±0.18km2 of MCP 95% and 0.07±0.03km2(t=0.607, p>0.05) of FK 50% respectively. In seasonal home range and elevation use characteristics of MCP 95%, autumn(0.73±0.26km2) and summer(0.77±0.06km2) were the largest home range and spring(0.58±0.38km2) and winter(0.47±0.25km2) had a smaller home range and it showed that there was a difference between summer and winter home ranges(F=3.868, P<0.05). As a result of seasonal elevation analysis, elevation use was 435m(28.4%) in spring, 464m(26.7%) in summer, 414m(28.8%) in autumn, and 393m(21.2%) in winter, respectively. It showed that these gorals used higher elevation in summer(F=0.783, P>0.05). We could not analyze the characteristics of introduced gorals, because only introduced female gorals were used for this study. However, we could understand that habitat use characteristics were of statistical significance in introduced gorals from the analyses of their home range, seasonal home range and elevation use.

Osteoma is a slowly growing benign tumor composed of compact or cancellous bone and usually found in paranasal sinuses.Lobular capillary hemangioma is a rapidly growing lesion usually affecting skin and oral mucosa. Both lesions may occur at any age group but most frequently in the third decade. The authors experienced a case of concurrent osteoma and lobular capillary hemangioma in the middle turbinate, which were removed via endonasal endoscopic approach. Concerning our case, we speculate that the slow growth of the osteoma may have caused inflammatory change on nasal mucosa, resulting in lobular capillary hemangioma. We report a case with a review of literatures. (Korean J Otolaryngol 2006;49:339-42)

Mucous membrane plasmacytosis is a rare benign condition characterized by plasma cell infiltration of the mucosa of upper aerodigestive tract. The lesions typically produce a cobblestone or warty appearance of the larynx, pharynx, palate, lips, mouth, tongue and trachea. Histologically, the lesions are characterized by a diffuse expanse of inflammatory cells situated in submucosal tissues, composed mainly of mature plasma cells with scattered polymorphonuclear cells and lymphocytes. Immunohistochemistry for κ, λ light chain showed polyclonal immunoglobulin content in all cases examined. A variety of medical and surgical treatments have been tried but none has led to improvement in the condition. In this study, we report, with a review of literature, a mucous membrane plasmacytosis arising from oropharynx in a 30 year-old female patient.
