조직에서 IT에 투자함으로써 납득할만한 가치를 얻고 있는가에 대한 물음에 많은 경영진과 의사결정권자들은 확신을 하지 못하고 있는 상황이다. 또한 조직의 IT 역량이 조직의 경쟁력 향상에 기여하고 있는가에 대한 부분도 크게 다르지 않다. IT프로젝트는 의뢰 IT부서가 담당하고 있으며, IT 투자 또한 전사 차원의 전략인 관점보다는 전술적 수준의 이니셔티브로 인해 적지 않은 자원을 낭비하고 있는 실정이다. 이러한 상황에서 IT 거버넌스에 대한 필요성과 개념에 대한 올바른 인식이 필요하게 되었으며, 그 접근 방법으로써 ITA를 비롯하여 많은 방법론들이 대두되고 있는 상황이다. 이에 우리는 정부부처 및 공공기관을 대상으로 ITA를 기반으로 정보자원을 관리하고 있는 조직들을 대상으로 IT 부분에 있어 어떠한 의사결정 형태를 갖고 있는지 연구하였으며, 본 연구에 관한 자세한 내용은 다음과 같이 논의 하였다.

The purpose of this study is to investigate the types and processes of corporate philanthropy programs on forestry in Korea 500 largest companies. The result shows that 75 companies of Korea 500 companies (15.0%) participated in corporate philanthropy program related to forestry and there are 113 programs that those companies are proceeding. The types of 108 programs can be divided into 5 parts; 1) volunteer work, 2) creating forests & management, 3) one-time planting work, 4) forest education, 5) training experts & job creation. Among them, volunteer work (55.6%) and creating forests & management (29.6%) showed high proportion. The process of programs depends on their types. The volunteer and one-time planting work were mainly proceeded directly by corporate volunteer organization. But creating forests & management, forest education and training experts & job creation were usually proceeded in consort with local governments, NPOs and NGOs, and so on. These results show that Korean corporate philanthropy in forestry is progressing to strategic philanthropy through participation and partnership of various social groups. This shows the possibility to progress corporate community investment (CCI) with forest education and training experts & job creation.

This paper presents a new framework for design and economic evaluation of wind energy-based electricity supply system. We propose a network optimization (mixed-integer linear programming) model to design the underlying energy supply system. In this model we include practical constraints such as land limitations of onshore wind farms and different costs of offshore wind farms to minimize the total annual cost. Based upon the model, we also analyze the sensitivity of the total annual cost on the change of key parameters such as available land for offshore wind farms, required area of a wind turbine and the unit price of wind turbines. We illustrate the applicability of the suggested model by applying to the problem of design of a wind turbines-based electricity supply problem in Jeju. As a result of this study, we identified the major cost-drivers and the regional cost distribution of the proposed system. We also comparatively analyzed the economic performance of on/off shore wind farms in wind energy-based electricity supply system of Jeju.

가상수의 흐름을 보다 가시적으로 파악하기 위하여 대두된 개념이 물발자국(water footprint)이다. 이는 흔히 사용되고 있는 생태발자국(ecological footprint)이나 탄소발자국(carbon footprint)에 착안하여 도입된 개념으로 한 국가의 물발자국은 직 간접적으로 물건이나 재화를 생산하는데 국민이 소비하는 물의 총량으로 정의된다. 물발자국을 내적/외적으로 단순히 구분하여 산정하는 방식이 진화하여 1단위의 생산에서 유통 및 서비스까지 확대하여 그 전 과정을 모두 포함하는 물발자국 산정방식이 도입된 것은 최근의 일이다. 직접적인 물사용과 간접적인 물사용을 구분하여 물발자국을 산정하고, 그 위에 물의 성질에 따라 green water, blue water, 그리고 grey water로 각각 개념을 상세화하여 물발자국을 산정하는 방안이 도입되었다. 2009년 물발자국 산정의 표준화를 위한 스위스의 제안이 ISO에 제출되었고, 각 국가들에 의한 투표가 진행되어 2010년 물발자국 국제표준안이 채택되었다. 본 연구는 이러한 국제기구에 의한 일련의 국제표준화 작업을 대상으로 진행되었다. 2014년 ISO/TC 207 국제총회가 개최되어 환경경영시스템(SC1), 환경감사(SC2), 환경 라벨링(SC3), 환경성과평가(SC4), 전과정평가(SC5), 온실가스관리(SC7)의 6개 분과위원회(Sub-Committees)가 구성되어 세부논의가 진행되었으며, 이러한 과정을 분석함으로서 물발자국 국제표준(ISO 14046)과 향후 우리나라의 대응방안을 고찰하였다. 물발자국 국제표준(ISO 14046) 제정을 통해 물발자국의 필요성 및 중요성에 대한 국가 간 합의는 도출되었으나, 적용시기 및 세부적인 방법론 등에 대한 이견이 여전히 존재하고 있다. ISO 14046의 실질적 적용에 필요한 세부사항과 관련된 기술보고서 작업초안(WD 14073)은 작업반(SC5/WG8)에서 진행되고 있다. 그러나 물발자국 국제표준이 국가 간 무역장벽이나 특정국의 진입을 막는 수단으로 사용될 수 있는 점 등 실질적으로 국제표준의 도입에 따른 문제점 역시 존재한다. 본 연구에서 제시된 국제표준의 도입 방안을 통하여 가상수무역의 국제적 선점효과를 기대함과 동시에 수자원의 유효한 활용을 기대할 수 있을 것이다.

Having gone through the international financial crisis in 1997, the Korean government has sought a new future economic breakthrough. In this line, the government chose the cultural contents business and has supported this area intensively. With the cultural contents promotion policy initiated to foster the world-class culture business based on the traditional Korean culture, Andong, which has diverse cultural traditions, was rediscovered. The Andong local government and the local power elites decided that this promotion policy can not only be an opportunity to invigorate the sluggish local economy, but also help eliminate the old-fashioned image of Andong, and thus actively promoted the cultural contents business. However, there's a conflict among the local elites over which cultural tradition should be chosen as a genuine local cultural tradition. The different views and efforts regarding the cultural identity of the region by each entity not only contributed significantly to the recovery of the local economy by revitalizing tourism, but also helped the region gain an advantageous position in competition with other regions over limited resources. This progress became the groundwork for attracting major institutions and facilities, which are essential for the revitalization of the local economy.

This study estimates an energy efficiency of 16 metropolitans and provinces in Korea, and measures potential energy-saving and carbon emission reduction using a non-radial data envelopment analysis method. Based on energy mix scenarios, this study also evaluates the impact of changes in energy structural adjustment on a regional environmental performance. The empirical results show that, on average, 12.70% of energy consumption and 13.73% of carbon emission can be reduced by improvement in energy efficiency, and low efficiency of oil usage in metropolitan cities is a major source of the inefficiency. Furthermore, it is found that energy mix policy should be considered to achieve an extra energy-saving and carbon reduction.

Rhododendron micranthum is an endangered species in Korea. In order to develop the strategy of gene diversity conservation, estimation of the amount of genetic diversity, the genetic variation and relationship in the native populations of Rh. micranthum was performed on the basis of AFLP and RAPD analysis. Analysis of 56 accessions derived from 6 populations of Rh. micranthum with four AFLP primer combinations and ten RAPD primers detected a total of 33 polymorphic AFLP fragments and 15 polymorphic RAPD fragments, respectively. By UPGMA cluster analysis with molecular markers, the 56 accessions were grouped into three major clusters at 73.3% genetic similarity; group I consists of most accessions of populations I, II, IV, V and Ⅵ, group II consists of 7 accessions of population III, and group III consists of only two accessions of population IV. The geographic locations of the most accessions derived from six populations were not related to their position in the UPGMA cluster analysis, except for several accessions of populations III and IV. The genetic similarity of among six populations measured by AFLP and RAPD markers ranged from 0.66 to 0.99. Among them, population Ⅵ showed the highest GS with means of 0.87, while population I showed the lowest GS with means of 0.78. This result will be useful for designing the strategy of conservation in the native populations of Rh. micranthum.

Discovering customers' behavioral patterns from large data set and providing them with corresponding services or products are critical components in managing a current business. However, the diversity of customer needs coupled with the limited resources suggests that companies should make more efforts on understanding and managing specific groups of customers, not the whole customers. The key issue of this paper is based on the fact that the behavioral patterns extracted from the specific groups of customers shall be different from those from the whole customers. This paper proposes the idea of pre-segmentation before developing customer classification models. We collected three customers' demographic and transactional data sets from a credit card, a tele-communication, and an insurance company in Korea, and then segmented customers by major variables. Different churn prediction models were developed from each segments and the whole data set, respectively, using the decision tree induction approach, and compared in terms of the hit ratio and the simplicity of generated rules.
