The purpose of this study is to measure the factor of determination on satisfaction level of the Jeonju International Film Festival. A study is analysed through research that is consisted of satisfaction factor#s items of 32 local festival visitor to study factors of determination of local festival visitor#s satisfaction level. This research data extracted 6 factors, which are access and souvenir, food/lodging, information/service, event/pastime, and convenient facilities. In conclusion, the festival is likely to attract more tourists and make them satisfied if better content of the festival is provided. There, most of the tourists need to becoming cleared to be satisfied due to its values of culture recognition through various contents of the festival, fun factors, food/lodging factors, and various programs.

Purpose - The purpose of this paper is to examine IKEA in the context of corporate social responsibility to determine the reasons, if any, as to why IKEA has had more success in the implementation of its CSR policies and Code of Conduct where many other multinational companies seem to have failed. Research Design and Methodology - This is a case study, an analytical approach, which focuses on exploring and analyzing the CSR policies to measure IKEA's ethical behavior in a business environment. Results - IKEA stands out as a multinational company whose CSR policies are ingrained into the business itself as a part of its ethical operations, rather than a marketing event. Conclusion - Beyond profit, IKEA actively works together with its suppliers and the nation states to eradicate the harmful social causes of the various challenges it faces in the global business environment.

In this study, we identify the variables that affect the number of crime and spatial correlation in the Seoul metropolitan area, in addition, we measure the relative risk on the incidence of crime by a Poisson regression model. We suggest a statistical methodology to make a risk map for crime based on relative risk instead of the total event of crime by region using the Geographic Information System. To demonstrate the use and advantages of this methodology, this study presents an analyses of the total crime count in 25 wards in the Seoul metropolitan area.

A curriculum is a measure of how high level of knowledge is educated to students affiliated to university institutions, and is used as an indicator evaluating usefulness of the university institutions. For this reason, Designing and assessing curricula is a critical to high education institutions. However, in the case of development and quality assessment of a curriculum with a traditional way, finding a right curriculum which a designer intends is a time consuming and error-prone process. Therefore, in order to improve these problems, we propose the curriculum design engine using SES (System Entity Structure) / DEVS (Discrete Event System Specification) Framework in this paper. The SES describes all possible combination of curricula for students. The DEVS framework provides a simulation environment for models created from the SES by the students. The proposed engine will show appropriate curricula for students after a simulator appropriately filters students' requirement, according to conditions.

We have proposed an objective evaluation method using ESNR as the measure of approximation by the visual model, which coincides with MOS, a subjective evaluation method. For two-value images, we have used five kinds of modulation methods: 1) ordered dither, 2) least mean error, 3) pulse density low division, 4) simple two-value, and 5) random dither methods. The purpose of this paper is to investigate the validity of ESNR, by comparing the proposed method together with the existing representative methods such as PSNR and WSNR, with the subjective method MOS. The results of a series of experiments show that the ranking by MOS coincides with ESNR, though does not coincides with PSNR and WSNR.

Adverse effects caused by the surveillance test for the components of nuclear power plant involve plant transients, unnecessary wear, burden on licensee's time, and the radiation exposure to personnel along with the characteristics of each component. The optimization methodology of STI and AOT has been developed and applied to AFWPs of a reference plant. The approach proposed in this paper consist of the resole in minimal mean unavailability of the two-out-of-four system with adverse effects are analytically calculated for the example system. The surveillance testing strategy are given by the sequential test, the staggered test and the train staggered test which is a mined test scheme. In the system level, the sensitivity analyses for the STI and AOT, are performed for the measure of the system unavailability of the top event in the fault tree developed for the example system. This methodology may contribute to establishing the basis for the risk-based regulations.

Construction equipment is a major energy consumption source in construction projects. If 10% reduction of the diesel fuel usage is achieved in the construction industry, it may reduce 5% of the total energy usage. Energy saving operation is a major issue in equipment-intensive operations (e.g., earthmoving or paving operations). Identifying optimal equipment fleet is important measure to achieve low-energy consumption in those operations. This study presents a system which finds an optimal equipment fleet by computing the low-energy performance of earthmoving operations. It establishes construction operation model and compares numerous combinations using alternative equipment allocation plans. It implements sensitivity analysis that facilitates searching the lowest energy consumption equipment fleet by enumerating all cases.

This paper proposes a methodology to measure the risk level in real-time for Business Activity Monitoring (BAM). A decision-tree methodology was employed to analyze the effect of process attributes on the result of the process execution. In the course of process execution, the level of risk is monitored in real-time, and an early warning can be issued depending on the change of the risk level. An algorithm for estimating the risk of ongoing processes in real-time was formulated. Comparison experiments were conducted to demonstrate the effectiveness of our method. The proposed method detects the risks of business processes more precisely and even earlier than existing approaches.

정보추출이란 자연어로 작성된 문서 집합에서 원하는 정보를 선택하여 구조화된 표현으로 생성하는 것을 말한다. 문장 단위로 정보 추출 작업을 수행할 때 추출되는 정보를 보유한 문장을 이벤트 문장이라고 정의하고 이러한 이벤트 문장의 구조를 분석하여 최종적으로 유용한 정보를 추출하기 위해서는 이벤트 문장의 구조를 파악하기 위해 이벤트 문장을 단문으로 분할하여 구조를 분석한다. 본 연구에서는 단문 구조 분석을 위해 일반적인 한국어 문장의 특성과 용언의 조사 정보를 이용하고 이러한 정보로 분석할 수 없는 문장에 대해서는 공기 정보를 사용한다. 사용되는 공기 정보는 개체명이 많이 사용되는 이벤트 문장의 특성을 이용하기 위하여 개체명으로 확장된 명사(개체명)-조사-용언의 공기 정보를 구축하여 사용한다. 개체명 확장된 공기 정보는 일반 공기 정보에 비해 이벤트 문장에서 F-Measure 기준으로 약 2%의 성능향상을 보인다.

We measure the hemodynamic responses during the 4 kinds of tasks on the motor cortex in the right and left human brain by using near-infrared spectroscopy. The experimental results show that the change of concentration of oxy-hemoglobin is larger than that of deoxy-hemoglobin and the change of concentration of chromophores induced by finger and arm related task show more activations than that of leg.
