  • Remodeling the existing building structure by recycling has great advantages compared with reconstruction in terms of environmentally contributions and reduced use of national resources. And no matter the existing floor area ratio, extension up to 30% of the exclusive using area and short project period have made remodeling a good alternative to reconstruction. However, the residents of aged housings that were being remodeled are either abandoning the remodeling project and turning to reconstruction. The main reason is remodeling project cannot increase the number of householders. In principal, it is prohibited to increase the number of floors during remodeling due to matters of safety. That is, all remodeling construction costs are borne by the residents, which leads to great financial pressure. Therefore, in order to improve these conditions, the residents' burden of remodeling charges should be reduced, and one of the ways to do so is to increase the number of householders. In this study, there will be suggestions of alternatives, including the story increase during remodeling, and compare the burden of remodeling charges on each of the residents, between proposed alternatives and the current remodeling plans by calculating the construction costs in order to prepare a foundation for a system that will promote remodeling.

  • The collapse of underground mine development void for mineral resources can cause the subsidence of ground surface. In order to prevent the subsidence of ground, data such as maps or pictures of past mining site is important information for current mine reclamation works. In particular, mine subsidence management was based on mining maps and pictures. The process of the mining area surveys, safety evaluation, and ground reinforcement are normally possible with information such as maps and pictures in past mining. During the Japanese colonial period and 1960's, a lot of mines were developed in Korea indiscriminately. However, mining information at that time is limited to use. In the future, mining information will become even more rare. MIRECO intends to establish a realistic alternative solution. In this study, the basic numerical information of developed mine tunnels in Korea is statistically reviewed, and advanced underground cavity measuring technology was studied. 4,473 mine tunnel opening data of 1,784 abandoned mines in korea were collected and sorted. As a result of the analysis, the average value of small mine tunnel openings in Korea was 1.982 m in height and 1.959 m in width. The mean value of shape factor was analyzed as 0.485. The summary of these numerical mine data will be helpful for understanding and researching Korean abandoned mines. Therefore, the development of measurement technology for abandoned mine cavities and tunnels is expected to facilitate more effective mine subsidence management works in Korea.

  • The syndicated investment strategy of venture capital has merits such as reductionof investment risk, efficient management of investment resources, and information asymmetry mitigation. This study analyzes the investment strategy and network of venture capital by collecting and analyzing investment information of Korean venture capital on Korean start-ups for three years from 2014 to 2016. We could not find statistically significant association with the choice of syndicated investment of the stage of start-ups, the venture capital expertise (investment concentration), internal competence (number of workforce and professional manpower), and the breadth of investment network. As a result of this study, the factors that determine venture capital 's syndicated investment in Korea are only the financial factors such as the size of the investment amount and the size of the fund besides the business field of the invested company. The results suggest that the majority of venture capital firms in Korea may not customize their investment strategies in terms of their expertise or inherent business risks of invested companies.

  • 한국수력원자력(주)는 20기의 원자력발전소를 운영하고 있으며, 원전에서 발생되는 전기로 우리나라 총전력의 약 40%를 담당하고 있는데 이 과정에서 필연적으로 사용후연료가 발생하게 된다. 사용후연료는 재활용 여부에 따라 자원 또는 폐기물로 간주되는 성격을 지니고 있다. 그러나 우리나라는 사용후연료에 대해서는 아직 확실한 방침이 정해지지 않아 이의 저장 시설이 필요하며 현재 원자력발전소 내 사용후연료 저장조와 건식 저장 시설에 임시 저장하고 있다. 사용후연료는 2006년 말 기준으로 8,670톤이 저장되어 있고, 발전소 내에 설치된 기존 시설의 저장 능력이 포화되는 것에 대비하여 조밀 저장대 설치, 호기 간 이송, 공동 저장, 습식 저장 시설 확장 및 건식 저장 시설 추가 건설을 통해 단계적으로 저장 능력을 확장하여 2016년까지 발생되는 사용후연료를 저장할 계획이다. 그러나 제253차 원자력위원회(2004. 12. 17)에서 2016년 이후 사용후연료 관리 방침에 대해서는 중간 저장 시설의 건설 등을 포함하여 충분한 논의를 거쳐 국민적 공감대하에서 추진하기로 결정됨에 따라 현재 공론화 방안 연구와 대내외적인 공론화가 진행되고 있다.

  • 의사결장지원시스템은 다양한 분야에 적용되어 왔으며, 그 중 수자원 및 수질 관련 분야에도 다각적으로 적용되어 왔다. 본 연구에서는 미 농무성의 자연자원보전국(NRCS, Natural Resources Conservation Service)에서 개발한 유출곡선법(Curve Number Method)과 EMC(Event Mean Concentration)을 사용한 L-THIA(Long-Term Hydrologic Impact Assessment) 수문/수질 모형을 강우자료 데이터베이스, 웹기반 지리정보시스템, 웹 사용자 편의 시스템과 통합한 수문/수질 L-THIA web 의사결정지원시스템을 개발하였다. L-THIA web은 도시계획가나 지방자치단체, 또는 지방의 공동체가 사용할 수 있도록 쉽고 단순한 사용자 편의 시스템을 제공하고 있으며, 미국의 50개 본토의 주와 카운티(County) 이름으로 기상자료와 수문토양분류(Hydrologic Soil Group)을 인터넷 지리정보시스템을 이용하여 제공하고 있다. 본 연구는 지방자치단체 및 지역공동체의 실무자를 사용자로 수문/수질 평가 및 관리를 위한 시스템으로 유용하게 활용될 수 있을 것으로 사료된다.

  • 타이에서 작물 생산성이 낮은 주요 원인은 토양중 식물양분인 질소, 인산 및 유황의 부족에 기인되었다. 이같은 부족현상은 원래 척박한 토양에 충분한 시비가 이루어지지 못한데 기인된다. 더욱이 유황을 함유하지 않은 고농도 복합비료의 사용으로 이와같은 현상이 심화되었다. 최근 농경지 토양 분석결과 모집단의 $70\%$에서 유황부족이 나타난 것으로 확인되었다. 타이에서의 유황연구 사업은 유황과 작물생산성과의 관계를 이해하는데 큰 도움을 주었다. 유황부족 토양은 농림부에서 현지포장 시험에 의해 1974년에 밝혀졌다. 1985년부터 1992년까지 국제농업연구 호주센터와 UN 식량농업기구의 공동으로 인산과 유황비료의 효율적인 관리제도 방법을 개발하였다. 이에 부가하여 열대작물 재배체계에서 인산과 유황결핍 진단을 위한 토양 및 식물체 분석을 발전시켰고 또한 대체 유황 자원도 검토하였다. 끝으로 농경지에서 토양 유황 분포도는 유황비료를 추천하는데 보다 좋은 방법으로 이용되었다.

  • With the international increasing of the important of oceanic researches related to climate changes, resources conservation and development and the advanced application of oceanic researches, advanced countries in ocean have developed the systematic management systems for oceanographic instruments. Despite the increasing realization of need for the establishment of management system, no systematic management system has been built in KOREA. There is an ungently need to construct the efficient and professional maintenance and management system of oceanographic instruments that are extremely expensive for meeting the increasing demands of oceanographic observation and investigation. In this paper, the present possession of oceanographic instruments in KOREA and the need for the establishment of management systems for oceanographic instruments are discussed. In addition, we introduce the total management system for oceanographic instruments using a RFID(Radio Frequency IDentification) at KORDI and discuss the necessity of the introduction and establishment for producing high quality data in oceanic researches.

  • This study targeted volunteers to identify the variables that affect the attitude for participating in the volunteer activities going forth, and their effect. The independent are consisted of personal characteristic variables, participation related variables, management process variables. As for the dependent variables, they included the will to participate continually and degree of participation. The major findings are as follows : First, volunteer work agency try to activate housewives' participants. Second, the volunteer work agency need to improve and develop the programs which are consisted of more 3-hours per participation and three times per month. Third, so the motivations are the most important variables affect the sustainability, volunteer programs must be established to realize effective experience learning and social participation. Forth, a systematic management for the volunteer programs must be established to activate more participation.
