본 연구는 무등산 국립공원 방문객들의 인구통계학적 특성 및 사회경제학적 특성을 조사하여 공원방문객 수요증진을 위한 마케팅전략차원의 정보제공을 목적으로 수행되었다. 이 연구를 수행하기 위해서는 적절한 모형설정이 중요하다. 이른바 종속변수가 이산확률분포를 가진 이산형 변수일 경우, 연속확률분포의 자료 분석에 적합한 회귀모형을 설정한다면 추정치에 대한 심각한 오류가 발생하기 때문이다. 따라서 본 연구의 자료 분석은 포아송모델을 통해 수행되었으며, 자료의 특성이 과산포를 보였기 때문에 이를 고려할 수 있는 보다 적합한 모델로 음이항 포아송모델을 설정하여 최종적으로 파라미터를 추정하였다. 그 결과, 수요자의 연령, 직업, 방문선호계절, 동반유형, 주 5일 근무제 그리고 선호관광형태 등이 방문객 수요에 긍정적인 역할을 하고 있는 것으로 파악되었으며, 이 주요영향변수들을 바탕으로 국립공원 측에 핵심시장에 대한 특성과 그들을 위한 마케팅 전략 및 정보 등을 제공할 수 있었다.

Infinite competition on ICT industries is starting again. The basis of competence over global dominance will be human resource, a global ecosystem for products and national agenda for science and technology, etc.. This paper presents the six solution for the Global Competitiveness and Coexistence of Korean ICT Industries. Korea should nurture the brand of "World Best Korean ICT Forever" to secure technical competency of ICT related fields in global market. All ICT technologies should be aligned to global standard and market demand from beginning and the ecosystem around product needs to be established. System framework for utilizing the resource of core SW experts must be established. Through global partnership with China as manufacturing base for Korea-developed products, technical competency can be maintained including product planning. Security measure for technical assets is mandatory. Finally, core technology that will drive the future of ICT industries in Korea should be regarded as core subjects.

The use of renewable energy sources and energy storage systems is increasing due to new policies in the energy industries. However, the increase in distributed generation hinders the reliability of power systems. In order to stabilize power systems, a virtual power plant has been proposed as a novel power grid management system. The virtual power plant plays includes different distributed energy resources and energy storage systems. We define a core virtual power plant technology related to demand response and ancillary service for the cases of Korea, America, and Europe. We also suggest applications of the proposed virtual power plant to the vehicle-to-grid market for restructuring national power industries in Korea.

In this study, the evaluation of environmental performance of the building energy system of domestic commercial sector was carried out. Based on the theory of linear programming model, we established an evaluation model satisfying object functions and constraint conditions. Employing the model, the evaluation of building energy system was performed under the consideration of cost and environmental constraint conditions. As an evaluation tool, MARKAL (MARKet Allocation) known as a market distribution model was employed. We analyzed scenarios of Case I (Base Scenarios) through Case IX established by the combination of the components of building energy system such as glazing, building skin, core, and heat source system. According to the results of the evaluation, highest contribution on the useful energy demand was obtained from the building energy system combined with solar heat source system, when the total amounts of $CO_2$ exhaust as an environmental constraint condition is assumed to be the level of 1995.

This study was carried out in the Haenahm county as a part of project, the'89 Comprehensive Planning of Rural Area. In order to increase household income of rural area and to meet increasing tourism demand in urban area, several tourism development directions and strategies were suggested in terms of resources, services, and transportation. The major results of this study are summarized as follows ; 1) Core tourism market has to be maintained by inforcement of unique image of the Haenahm county, such as the southern extremeity of Korean peninsula and tourism resources rich land. 2) New tourism products need to be introduced to attract fringe market of this area by use of natural and cultural resources in the Haenahm county, such as terrain, climate, provincial park, music, dance and artifacts. 3) image of this county as a touristic resort would be escalated by development of high quality andclusterized accommodation in urbanized area of the Haenahm county 4) Development of private lodging, production of local brand by native food, beverage and artifacts, introduction of festival by folk song and folk dance would be helpful to stabilize a seasonal fluctuating demand level of ourismandlocalresidentsincome. 5) Diversification of tourism product needs to be provided for tourists in order to increase chances for enjoyment in the destination and to be involved in socially comfortable atmosphere. 6) Package tour by diversification of touristic subregions in this county and linkage system with touristic regions of other counties would helpful to lead visitors to stay long, resulting in increased expenditure.

Due to the increasing demand for convenience and simplicity, Home Meal Replacement (HMR) has become a key trend in the food service industry. This study researched the current consumer trend and analyzed the national and international HMR product trend, aiming to find useful insights for the field. Results showed that in order to expand the HMR market demand, it is possible to consider diversifying the product category by making customized premium products, such as products for the elderly, infants, patients, and sports players, or products with enhanced nutritional fortification. From the industrial aspect, centralization through Central Kitchen (CK) and implementation of the scientific and advanced ISO and HACCP system are necessary. Lastly, to develop high value-added HMR products, it is deemed essential to utilize the so-called 'food tech', the technology which integrates core technologies of the fourth industrial revolution into the food industry.
