The degree of air pollution is usually presented in terms of concentration. But, in evaluating the environmental impacts or air pollution control policies, the concentration values need to be interpreted in terms of damage effects on property and human health. The damage effect varies with the types of pollution, subjects and land use pattern of an affected area. Therefore, this study is aimed at developing a method of analyzing effects of various types of air pollutions on surrounding environmental setting with the EIMS (Environmental Information Management System) developed for land suitability analysis. Using the method formulated in this study, the long- term effects of such pollutants as $SO_2$ and HF on types of vegetation and residents, and potential, short-term effects of HCl leak accidents from manufacturing facilities in Ulsan and Onsan Industrial complex are analyzed. The presentation of the damage effects of air pollution rather than the concentration of pollutants will be useful for the preparation of environmental impact statements, the formulation of environmental policies, and the development of land use plans in heavily industrialized areas.

탐지룰을 기반으로 하는 보안 시스템들은 신종 인터넷 웜에 대응할 수 없다는 문제가 있다. 본 논문에서는 탐지룰을 사용하지 않고 인터넷 웜 공격으로부터 서버를 보호하는 악성 프로세스 및 실행파일 제거 시스템을 제안한다. 제안 시스템은 보호대상서버와 동일한 서비스 프로그램을 구동하면서 인터넷 웜에 의한 멀티캐스팅 공격을 탐지하는 제어서버와 제어서버의 지시에 따라 보호대상서버에 생성된 악성 프로세스와 악성 실행파일을 제거하는 에이전트로 구성된다. 제안 시스템은 탐지룰을 사용하지 않기 때문에 신종 인터넷 웜에 효과적으로 대응할 수 있으며, 기존의 보안 시스템들과 통합될 경우 보안을 더욱 강화할 수 있다.

According to the Korean Traffic Accident Analysis System (TAAS), more than 200,000 traffic accidents occur every year. Also, the statistics including auto insurance companies data show 1.3 million traffic accidents. In the case of TAAS, the types of traffic accidents are simply divided into four; frontal collision, side collision, rear collision, and rollover. However, more detailed information is needed to assess for advanced driver assist systems at intersections. For example, directional information is needed, such as whether the vehicle in the car accident way in a straight or a left turn, etc. This study intends to redefine the type of accident with the more clear driving direction and path by referring to the Negligence standards used in automobile insurance accidents. The standards largely divide five categories of car-to-car/motorcycle /pedestrian/cyclist, and highway, and the each category is classified into dozens of types by status of the traffic signal, conflict situations. In order to present more various accident types for auto insurance accidents, the standards are reclassified driving direction and path of vehicles from crash situations. In results, the car-to-car accidents are classified into 33 accident types, car-to-pedestrian accidents have 19 accident types, car-to-motorcycle accidents have 38 accident types, and car-to-cyclist accidents are derived into 26 types.

Resulting anthropometric data recently measured and cataloged through 5th national anthropometric survey that is called Size Korea is highly useful in clothing industries. This study aims at suggesting a statistical methodology for apparel sizing that reflects recent changes in Korean anthropometry and improves customer fitness. Based on previous research on body types such as triangular, rectangular, inverted body types, etc., factors that represent human sizes were extracted and then clustered into groups by their body types. These body type-based groups with respect to the factors obtained yielded a sizing system of which the interval of each factor is of equi-distance by their factor scores. However, each interval of the sizing system is non-linear in terms of individual anthropometric variables. The sizing system being proposed in this study was compared to that of KS K 0050 and had a broader coverage for the Korean population surveyed. The apparel sizing scheme is expected to improve customer fitness when applied to garment sizing and to provide more information on what percentage of population is included in each classification.

The purpose of this paper is to propose a notification service for preventing unexpected accidents which will be occurred by enlisted men's stress in Korean Army. For this purpose we first evaluate the enlisted men's stress with reliable evaluation tools through survey. A representative sample size of about 1,500 enlisted men from all seven unit types was selected and surveyed considering types of unit, ranks, and regional characteristics. In the second, we analyse the results of level of stresses and stress reactions to distinguish high potential enlisted men who will happen to accident. Through the second step, we know enlisted men's stress reactions are different depending their unit types. Therefore the basic information about their stresses will be judged respectively according to their unit types. In the final step, we propose a notification service that offer the information about high potential enlisted men who will happen to accident to their managers rapidly through military Intranet and information systems. Their managers will get the previous information about occurrence of unexpected accidents and have time to check various things before they are occurred. We hope the proposed service contributes to prevent unexpected accidents and reduce the effort of military managers. Furthermore this paper offers several recommendations to apply the proposed service to Korean Army.

이 연구의 목적은 개인별 성향이나 성격 유형에 따라 선호하는 도서에 차이가 있음을 전제로, 어린이 청소년을 위한 추천도서의 책소개 정보를 활용하여 개인별 성격유형에 적합한 도서를 합리적으로 추천할 수 있는 서평 자동분류시스템을 개발하는 것이다. 연구에서 사용한 데이터는 국립어린이청소년도서관에서 제공하는 501권의 유아 및 아동도서를 대상으로 하였다. 실험에 활용된 2가지 기계학습 모델(비선형 커널 및 선형 커널) 각각에 대해서 총 6가지의 색인어 가중치 계산 방법과 자질 선택 방법, 그리고 10가지의 자질 선정 임계치 조합으로 구성된 360개의 분류 모델들을 구성하고 각각의 성능을 측정하였다. 전체적으로는 선형 커널을 이용한 SVM 기반 학습 방법(LIBLINEAR)이 비선형 분류를 지원하는 LibSVM(RBF 커널) 모델보다 더 나은 성능을 보이는 것으로 나타났다. 다만 성능 측정 결과는 뉴스 기사나 논문을 대상으로 한 문헌 분류 성능에 비해서 낮은 것으로 나타났으나, 합리적인 분류 기준이 존재하는 뉴스기사나 주제 분류에 비해서 성격 유형 기반 분류는 그 난이도가 높다는 것을 감안할 때, 초기 실험 결과로서의 의미는 있다.

본 논문은 얼굴 검출을 이용한 숏의 유형을 판단하는 방법론을 제시한다. 클로즈 업 숏이나 미디엄 숏, 롱 숏과 같은 숏의 유형은 영화의 서사 구조를 파악하는 주요한 단서이다. 클로즈 업을 통해 감독은 등장인물의 감정 상태를 묘사하고 롱 숏을 통해 인물이 처한 상황이나 배경을 묘사하게 된다. 인물의 심리나 감정의 변화, 인물이 처한 상황을 묘사하는 숏의 여러 유형은 인물과 카메라의 거리에 의해 결정된다. 따라서 화면에 등장하는 인물의 얼굴 크기를 알아내어 숏의 유형을 판단할 수 있다. 이를 위해 본 논문에서는 얼굴 검출을 통해 숏의 유형을 감지하는 방법론을 제시하고 시스템으로 구현하여 성능을 평가한다. 평가실험에서 클로즈 업 숏과 미디엄 숏의 감지 성능은 95%와 90%로 비교적 높게 나타났지만 얼굴의 윤곽이 불분명한 롱 숏의 경우 53.3%로 측정되었다.

The purpose of this study is to investigate the evaluation perspectives of IT business value and empirically analyze the differences of evaluation perspectives between ex ante evaluation and post implementation evaluation, and among various information system types. 4 evaluation perspectives which have been used in the previous studies and in the field of industry practices are financial, customer, internal process, and growth, which are based on the BSC model. Data of 98 information systems have been collected from 89 companies including manufacturers, banks, insurances, and stock trading companies. As results of multi-way MANOVA test, 3 out of 8 hypothesis have been accepted statistically. While the order of importance of 4 perspectives in ex ante evaluation is customer, financial, internal process, and growth, the order of post implementation evaluation appears to be much different : that is, internal process, customer, financial, and growth. These findings provide insights for both IT practitioners and researchers.

As the use of Internet being generalized, ordering system can be easily achieved on the Web so that the direct sailing system is replaced the various types of Built-To-Order system. It is important to give the up-to-date information to the end-user in order to build the Built-To-Order system. Recently, the way of providing information is updating the product related information continuously. In this study, we provide the method that can be streamlined Product Data Management System which manages a creation and update for product information into the direct BTO system in order to achieve the newest information. This methodology is not only transferring the information but also processing the information in an appropriate form. So this paper is going to cover the various point of view of information processing.
