Customizing system is acting a main role for the character production system of MMORPG. However, since using the high degree of freedom in MMORPG, these characters are too individual and lack of awareness. We can describe each character's emotional characteristics and understand the correlation of characters more easily by adjusting design factors capable of cognitive decision to characters. Game character developer should consider seeking efficient character design process that is suitable to MMORPG game environment and users for proper character recognition and promoting character preferences. In addition, this research being extended on the article vol.13, no.3, "A Study on Cognitive and Preference of Games' Character" on Korean Society of Basic Design in June 2012 issue and this study is expected to have effectives as one method for the purpose of this research is to inquire and present what type of relation lies between recognition and preference of game characters of MMORPG.

최근 우리나라에서 발생한 가뭄의 특징은 발생주기는 짧고 그 피해는 오히려 심화되는 현상을 보이고 있다. 효율적인 가뭄재해 관리를 위해서는 현재 뿐만 아니라 미래에 대한 전망이 선행되어야 한다. 본 연구에서는 국내에 적합한 월단위와 주단위의 가뭄전망기법을 제시하였다. 월단위 가뭄전망에서는 불확실성이 크기 때문에 앙상블 기법을 이용한 확률론적 가뭄전망을 하였고 이에 반해 주단위 가뭄전망에서는 기상청에서 제공하는 GDAPS를 이용하여 확정론적 가뭄전망을 하였다. 월단위와 주단위 가뭄전망 모두 강수, 유량, 지하수위를 인자로 하는 MSWSI(Modified Surface Water Supply Index)를 가뭄지수로 사용을 하였다. 월단위 가뭄전망에서는 과거 강수와 잠재증발산량 시나리오를 물수지모형인 abcd모형의 입력변수로 하여 최종적으로 유량과 지하수위 시나리오를 생산하였다. 확률론적 가뭄전망을 위해 MSWSI를 5개 구간으로 나누어 각 구간의 발생확률을 산정하고 실측자료로부터 산정한 MSWSI와 비교하였으며, AHS(Average Hit Score)를 이용하여 그 정확성을 평가하였다. 금강유역에 2001년과 2005년 7월부터 2006년 6월까지 적용한 결과, 월단위 가뭄전망의 AHS가 33.1로서 초보전망의 AHS인 20.0보다 높아 월단위 가뭄전망으로서 정확성이 있음을 확인하였다. 주단위 가뭄전망에서는 GDAPS를 abcd모형의 입력변수로 하여 확정론적 MSWSI를 산정하여 실측자료로부터 산정한 MSWSI와 비교하였으며, hit ratio를 이용하여 그 정확성을 평가하였다. 2001년 주단위 가뭄전망 결과, 주단위 가뭄전망의 hit ratio가 48.0으로서 초보전망보다 높아 주단위 가뭄전망 또한 효용성이 있음을 입증하였다. 계절별로 살펴보면, 갈수기의 가뭄전망이 홍수기보다 정확성이 높았다. 위 월단위와 주단위 가뭄전망은 적용기간이 짧아 가뭄전망의 정확성을 판단하기에는 아직 이르다고 판단되나 본 연구 결과를 토대로 장기적으로 가뭄전망을 수행하고 평가한다면, 가뭄전망에 대한 신뢰도가 더 높아질 것으로 사료된다.

This paper aims to explain the changes of social spatiality in rural areas as seen on a sloping scale in reference of population structure and utilization of territorial assets. Guessing from the population characteristics of rural communities and farming activities in Hwangsan village of Uichon-Myeon, Geochang-Gun and Hanam village of Chogye-Myeon, Hapchon-Gun, it will become a society characterized by super-aged intensification and large-scale crop cultivation. Deokgok-Myeon and Yulji village of Hapchon-Gun are required to intake outside residents. They have to understand the complementary cooperation and become conscious of the relationship between existing residents and relocated people in Yudong village of Yokji-Myeon, Tonyoung-Si. Due to a decreasing population and the phenomena of the 'super-aged', the efforts to revive the spatial function as a living and working space while utilizing territorial assets could be challenged in these case study regions.

The latest flow in Korea's distribution market is characterized by the deterioration of small/medium distribution market due to the rapid growth of multinational discount stores. As various multinational discount stores have merged with Korean discount stores (Homever acquired Carrefour and E-Mart acquired Wal-Mart), these discount stores have enlarged in size and dominated the market. On the contrary, small/medium distributors with relatively weak infrastructures are losing competitiveness in the market. Traditional marketplaces in local areas, in particular, are facing a serious crisis as they are neglected in the depressed local markets and have been beaten by the increasing discount stores and the diversifying distributors. The purpose of this study was to propose alternative plans to revitalize traditional marketplaces that are endangered by the unbalanced development of the distribution industry. This study analyzed the distribution performances and problems of Daejeon Metropolitan City and used the analysis to point out the problems specific to traditional marketplaces and propose a way to revitalize them. I hope that this study can help discount stores and small/medium distributors find balance in the market, and give traditional marketplaces the competitiveness to pursue sustainable growth.

쌀의 연간 생산량은 재배기술의 발달과 더블어 500만톤 이상을 꾸준히 유지해 오고 있는 반면에 식생활패턴은 점차 인스턴트화 되고 육류소비가 증가함으로써 1인당 소비량이 1990년 119.6kg에서 2002 년 87.0kg으로 급격히 감소하는 추세를 보이고 있다. 이러한 현상은 재고누적으로 이어져 2002년말 기준으로 1,190만석의 재고가 발생되고 있으며, 더욱이 WTO체제하에서 쌀시장 개방압력이 강화되고 있는 실정으로 앞으로 재고문제는 더욱 심화될 것으로 전망되고 있다. 이렇게 쌀이 남아도는 현실에서 국내 유통미의 품위는 싸라기 및 분상질립, 피해립, 이물 등 불완전립의 비율이 매우 높아 일본산이나 미국산에 비해 품질이 현저히 떨어지고 있어 고품질 가공을 통한 차별화가 시급히 요청되고 있는 실정이다. 따라서 본 연구에서는 최근 고품질 쌀 가공을 위해 설치 운영되고 있는 완전미 가공시설을 중심으로 완전미 가공기계장치의 구성 실태 및 제품의 품위 등을 조사분석하여 완전미 가공 기계장치의 개량요인을 도출하고, 이를 토대로 기계장치를 보완하기 위한 기초자료를 얻고자 하였으며, 그 결과를 요약하면 다음과 같다. 현재 보급되어 있는 완전미 가공시설의 구성형태는 기존 미곡가공시설에 홈선별기를 1대를 추가 설치한 제 I유형, 색채선별기1대 + 홈선별기 1대를 추가설치한 제II유형, 색채선별기 1대+입선별기 (개조) 1대를 추가한 제III유형으로 크게 나누어지고 있다. 이들 시설의 도정능력은 백미 가공시에는 I, II, III유형에서 각각 24.0, 27.7, 24.0톤으로 높았던 반면에 완전미 가공시에는 각각 3.1, 5,3, 4.5톤으로 처리능력이 크게 떨어지는 것으로 나타났다. 가공수율면에서는 일반백미로 가공시 72.0% 수준이었으나 완전미로 가공시에는 64.3%로 7.7%의 수율 감소를 가져왔지만 완전립률이 일반백미로 가공시 I, II, III유형에서 각각 89.08, 91.57, 88.00% 에서 완전미로 가공시에는 각각 98.02, 98.43, 97.78% 높아져 품질이 크게 향상되었다. 따라서 완전미 가공시설을 도입할 경우 쌀의 외관품질을 크게 높일수 있는 것으로 나타났다. 또 현재의 완전미 가공시설에 있어서 개량이 필요한 부분은 미숙립 등을 효율적으로 제거해 가공효율을 높이기 위해서는 입선별기의 개량이 요구되었으며, 홈선별기의 경우에는 선별정도는 문제가 없었으나 처리능력의 향상이 필요한 것으로 나타났다. 따라서 완전미 가공효율을 높이기 위한 선별기 개량연구를 계속 수행중에 있다.

Video-demand learning through E-learning continuously increases on these days. However, not all video-demand learning systems can be utilized properly. When students study by education videos not matched to level of their own, it is possible for them to lose interest in learning. It causes to reduce the learning efficiency. In order to solve the problem, we need to develop a recommendation system which recommends customized education videos according the study levels of students. In this paper, we estimate the study level based on the history of students' watching behaviors such as average watching time, skipping and rewinding of videos. In the experimental section, we demonstrate our recommendation system using real students' video watching history to show that our system is feasible in a practical environment.

Upon selecting preferred bidder in Public-Private Partnership projects, multi-dimensional procurement auction, where price factor and non-price factor are evaluated, is used. This paper tries to analyze bidding data in BTO road projects. It is shown that a winner tends to get higher score in bidding evaluation, which is partly due to increase in base score as well as fiercer competition among bidders. It turns out that score margin in non-price factor was determinant in selecting winner. Also, there was no competition when the level of bonus point was set too high. For price factor, it costs 730 million KRW per score in construction subsidy by government, while it costs 2.43 billion KRW per score in toll revenue. For non-price factor, it was estimated to cost 2.30 billion KRW. Based on the results, it was suggested that we should have appropriate level of bonus point for first initiator, change in scoring rule in construction subsidy part, adjustment of base score in evaluation.
