오늘날의 기업은 지속가능한 성장과 긍정적인 기업이미지 형성을 위해 사회공헌활동에 투자하고 있다. 기업의 사회공헌활동 투자금액은 증가하고 있지만 국민의 인식은 여전히 기업의 사회공헌활동에 대한 사실을 모르고 있는 것으로 파악된다. 본 연구에서는 이를 보다 구체적으로 살펴보기 위해 기업의 사회공헌활동을 4가지 차원(공익사업, 기부협찬, 자원봉사, 환경경영)으로 분류하고, A기업 임직원 173명과 D지역주민 345명을 대상으로 기업의 사회공헌활동에 대한 인식 차이를 살펴 보았다. T-test를 통해 기업의 사회공헌활동에 대한 지역주민과 임직원 사이의 인식 차이를 확인 할 수 있었다. D지역주민의 경우 환경경영에 대한 관심이 상대적으로 높았다. 그 이유는 철강 산업 이라는 A기업의 특성상 환경오염과 관련한 이슈가 많이 발생하므로 D지역주민은 환경문제를 중요하게 생각한다는 사실을 유추 할 수 있었다. 하지만 기업 임직원의 경우 환경경영보다는 공익사업과 자원봉사를 중요시하여 지역주민이 원하는 바를 충족시키지 못함을 알 수 있다. 본 연구는 A기업, D지역이라는 특정대상만을 연구대상으로 삼아 연구의 한계점이 존재하지만, 기업의 사회공헌활동을 지역적, 기업적 특색, 지역주민의 인식과 임직원의 인식 차이를 설명했다는 점에 특징이 있다고 하겠다. 또 이를 통해 기업의 사회공헌활동이 단순 기부에서 벗어나 지역단위의 필요성과 연계될 필요가 있음을 제시하였다는데, 본 논문의 차별성이 있다고 판단된다. In order to find strategic activities for social contribution, this study has figured out the perceived gap between regional residents and corporate members in the social contribution activities. Building on the earlier contemplated previous research, social contribution activity is classified four types, public services, donation, voluntary work, and environment management. As an empirical study, the survey was conducted by 173 members of "A" corporate and 345 residents of "D" community. This research found that "D" community residents concern a lot environment management of corporate. It means that "the steel industry" makes "D" community residents worry on environment issues. But corporate members think that public services and donation are main factors of social contribution activities, and this discrepancy could not meet the needs of community resident. So business should have concerns on specific local needs in order to do the effective social contribution activities.
In modern society, physical activity is gradually decreasing due to the development of transportation. Lack of physical activity also leads to a decline in physical strength, which in turn reduces the functioning of the cody's organs. A lack of exercise in modern people is apt to lead to acult diseases. This requires sports facilities for residents in the area, and thesee facilities will have a greater meaning if existing buildings on idle sites are utilized rather than new ones. Therefore, in this study, the sewage treatment plant in Gumi-dong, at the mouth of Yangjaecheon Stream was to be recycled to plant the complex sports and cultural facilities. This study proposes a plan to transform old buildings on idle sites into composite sprorts and cultural facilities through upcycling, and intends to reuse the space by forming a space for residents around them to have re-developed beauty, communication and exchange with various people, and time for self-development, It's not just a passing space, it's designed to be a place where diverse people gather in one place to develop their potential abilities. It is believed that the complex sports and cultural center with this property will reinvigorate the previously abandoned land and play a very effective role as a local landmark.
The main object of this paper is that it's possible to monitoring the movement of spatial structure, always monitoring system of Fiber Bragg Grating(FBG)Sensor is described and FBGs are well suited for measuring the movement in the part of the spatial structure(for example, cable, membrane and so on)under the pressure conditions. In order to measure the movement of long span structure, we need the measurable equipment that takes in many spots to measure. In the result of experiment, the fiber sensors showed good response to the pressure conditions.

Increase of empty houses are recognized in urban residential improvement areas as well as serious problem of empty houses in rural areas. empty houses effective strategies and additional measures are needed in slum area. But, there have been little research on empty houses issues. This study aims to determine the effective utilization of empty homes. This study analyzes a standards to tackle empty home issues, and analysis utilization of empty homes, danger, improvement. This classifies 12 category utilization of empty homes, this proposes preferential improvement ranking to using AHP Analysis. The implications of this research are useful in preparing the alternative strategies and statutory measures to tackle empty houses for residential improvement. Various criteria should be applied for each selective improvement to empty homes in order to improve the maintenance designation criteria. These findings improve the residential environment improve satisfaction in that you can plan the basis for an effective strategy can be. More sustainable in the future, including the analysis of various parameters in progress by being linked to policy measures that will be provided.

오동나무는 한국 전통 문화에서 오래전부터 인식되어 왔으며, 다양한 분야에서 종의 가치에 대해 연구되어 왔다. 그러나 종의 분포와 생태적 특성에 대한 연구는 미흡한 상황이다. 본 연구는 MaxEnt 모형을 활용하여 부산광역시 내 오동나무 두 종의 분포 경향 및 생태적 특성을 밝히는데 목적을 두고 있다. MaxEnt 모형은 현장 조사로 수집된 오동나무 종의 위치 정보와 지형, 기후, 잠재인간간섭도와 같은 환경 인자로 구축되었다. 연구결과 AUC 값은 오동나무와 참오동나무가 각각 0.809으로 모형의 정확도가 적절한 것으로 확인되었다. 분포모형에 따른 연구지역 내 오동나무와 참오동나무의 분포 경향은 두 종 모두 시가지, 나지가 밀집해 있는 도심위주의 분포를 나타냈다. 두 종의 잠재분포가능면적은 오동나무 137.4 ㎢, 참오동나무 135.0 ㎢로 확인되었으며, 중구, 동래구, 부산진구, 연제구 등에서 높은 확률로 분포하였다. 환경요인의 기여도 분석 결과, 오동나무와 참오동나무의 분포에 잠재인간간섭도가 약 50% 내외의 기여를 하는 것으로 확인되었고, 잠재인간간섭도와 양의 상관관계를 나타냈다. 해발고도는 두 종 모두에서 음의 상관관계를 보였으며, 해발고도가 증가할수록 자연서식처에서 자생종과의 경쟁이 증가하기 때문인 것으로 판단된다. 본 연구의 결과들은 오동나무와 참오동나무의 분포가 인위적 활동에 의존되어 있음을 수리적으로 나타내는 결과이며, 한국 전통경관과의 관련성을 암시하는 결과이다. 이러한 결과는 추후 오동나무의 활용 및 보존, 복원에 있어서 의미 있는 정보를 제공할 수 있을 것으로 판단된다. Paulownia species has long been recognized in Korean traditional culture and the values of the species have been researched in various focuses. However, studies on distribution and ecological characteristics of the species are still needed. This study aimed to identify distribution trends and ecological characteristics of two Paulownia species in Busan metropolitan city using the MaxEnt model. The MaxEnt model was established based on the environmental factors such as positioning information of the Paulownia species, topography, climate and degree of anthropogenic disturbance potentiality (ADP), which was collected in the on-site research. The study verified that the accuracy of the model was appropriate as the AUC value of Paulownia coreana and P. tomentosa was 0.809, respectively. In terms of the distribution trends of the two Paulownia species in the research area depending on the distribution model, they were both mainly distributed in downtown where built-up area and bare ground were densely concentrated. The potential distribution area of the two species was identified as 137.4 ㎢ for P. coreana and 135.0 ㎢ for P. tomentosa. The distribution probability was high in Jung-gu, Dongrae-gu, Busanjin-gu and Yeonje-gu. As a result of the analysis on contribution of the environmental factors, it was turned out that the degree of anthropogenic disturbance potentiality (ADP) contributed to distribution of P. coreana and P. tomentosa by about 50%, and the contribution of the environmental factors had a positive correlation with the degree of ADP. The elevation had a negative correlation with both the two species, which was considered because the species must compete more with native species in natural habitats as the altitude above sea level rises. The research findings demonstrated numerically that the distribution of P.coreana and P. tomentosa depended on artificial activities, and indicated the relevance with the Korean traditional landscape. These findings are expected to provide meaningful information in using, preserving and restoring Paulownia species.

1. CONTENTS (1) RESEARCH OBJECTIVES Especially, from 1990s information business has been increased as newest scientific technology has made development, and upbringing of venture businesses have been propelled for the uplift of national competitive power under the economical structure which stands on information. As a high-risk but high-earning business. Venture businesses was started for industrialization of new technologies and are known that they are suitable for multi-grade and small scale production. (2) RESEARCH METHOD In this study, I examined that what venture businesses can contribute to the spatial structure of a city under the situation that the spatial structure of Seoul has been distorted, and analyzed the spatial distribution and the changes in location of those venture businesses. (3) RESEARCH FINDINGS In the results of this survey, the most important problem is the move of spatial distribution of venture businesses. 2. RESULTS Venture businesses in Seoul have been spatially distributed centering around Teheran Valley, but now the number of venture businesses which leave Teheran Valley due It is expected that the growth and location of venture businesses could highly affect the formation of urban spatial structure and thus it is worth examining the spatial distribution and the changes in location of venture businesses.
Real-time formation of L10 phase of FePt nanoparticles in the gas phase during ultrasonic-spray pyrolysis is first discussed in the present study. Without any post heat treatment, L10 phase of FePt nanoparticles appeared at the temperature above 900℃ in the gas phase synthesis. X-ray diffractometry (XRD) and transmission electron microscopy (TEM) studies revealed that FePt nanoparticles less than 10 nm in size contained small volume of L10 fct phase. However, in other samples obtained at the temperature below 900℃, iron oxide phase co-existed and no evidence of phase transformation was found. Thus, it is anticipated that the time of flight of particles required for crystallization and phase transformation was extended according to the increase of the collision rate. Finally, magnetic properties represented by coercivity and saturation magnetization and functional groups on the particle surface were discussed based on VSM and FTIR results.
