Many studies on the acceptance of multi-national products have made academic contributions by offering various implications. However, there have been relatively few studies on the attitudes and behaviors of multi-national products depending on the purchasing tendency of consumers. The purpose of this study is to investigate how acceptance process of multi-national product, which is high involvement, appears by sorting consumers' purchasing tendency into rational consumption tendency, brand pursuit tendency, and consciousness of other people. Also, in order to supplement the measurement method of existing research, this study sought to analyze the acceptance behavior of consumers more precisely by classifying the situation before and after exposures of multi-national origin information on products. For this, 266 consumers were surveyed and statistical analysis was conducted through structural equation modeling. As a result of the research model, it was found that consciousness of other people has a significant effect on susceptibility and antipathy of multi-national product. In addition, antipathy against multi-national products has more powerful effect than susceptibility.

Geographical Information Systems(GIS) overlay analyses, while ideal for performing spatial searches on nominally mapped criteria, are of limited use when multiple uncertian criteria are concerned. But, Multi-Criteria Evaluation(MCE) techniques offer a means of making complex siting decisions, involving multiple criteria. The integration of GIS and MCE techniques became rational and objective approach to perform land suitability analysis on the basis of multiple criteria. An example application based on the search for suitable sites for the collective facility area in the kimhae daechung park using IDRISI is described.

Mobile Agent is an autonomous mobility technology is being applied in various fields. In particular, mobile agents execution in the Internet environment through the safe execution of the security must be guaranteed. Also, agent to run the agent, the agent's workload should be distributed. In this paper, a trust model based on the security mechanism of the agent execution is proposed. Proposed mechanism to ensure safe execution of the agent was not considered in existing relative researches for rational agent workload distribution and load balancing to improve throughput was. The proposed trust-based security mechanisms for agents to go through security analysis proved safe execution of the agent.

This study is to analyze open work status and conditions of cadastral surveyors and suggest improvement plans for working area of cadastral surveyors. The results are as below. Based on the analysis, this study suggests expansion of confirmation surveying for cadastral target range, ease of confirmation surveying standard for cadastral, and broader participation opportunities for cadastral surveyors in the cadastral re-survey project as improvement plans. If the Ministry of Land, Infrastructure, and Transport seeks legislative and policy improvement that can create more rational and ideal cadastral surveying conditions based on various reviews on improvement plans for working area of cadastral surveyors in this study will promote symbiotic development among cadastral surveyors.

Software Education will be implemented at elementary, middle and high schools starting in 2018. The goal of software education is to help students develop Computational thinking skills. Computational thinking is largely composed of abstraction and automation. However, the concepts related to abstraction are defined differently for each country, giving confusion to students and teachers. Therefore, in this paper several definitions of abstraction are compared and defined reasonably. And we proposed an abstraction teaching method and evaluation criteria in elementary school based on a reasonable definition. The definition of abstraction presented in this paper is expected to be able to present a solution to the problems encountered in the course of software education in the future.

The internet of things (IoT) using cloud computing is applied to nuclear industry in which the nuclear power plant (NPP) accident is analyzed for the safety assessment. The Fukushima NPP accident is modeled for the accident simulations where the earthquake induced plant failure accident is used for analyzing the cloud computing technology. The fast and reasonable treatment in the natural disaster was needed in the case of the Fukushima. The real time safety assessment (RTSA) and the Monte-Carlo real time assessment (MCRTA) are constructed. This cloud computing could give the practicable method to prepare for the future similar accident.

The character is one of most important interest-element in role playing game genres since it shows the individuality. In general cases, game players allocate points to talent clauses that they choose. However, it is not easy to provide the suitable character-growing to players in generic system since the cases are too simple and based on just humans choices. In this paper, we propose the character growing system based on the player type inference module. Growth morphology is determined by player's behavior or type. The determination is based on petri-net. Our experimental results and analysis show that our proposed approach is suitable for character-growing system.

In this paper, reasonable and effective building strategies of PPDR network is presented through investigating and analysing current policies for PPDR network of Korea and foreign countries. The research result shows that it is necessary PPDR network is designed and implemented considering currently transient status in aspects of PPDR-related technical roadmaps and existing PPDR networks. Also, in the transient period of more than 5 years, mobile broadband- based private PPDR network should be builded and it should be complemented by some commercial networks such as TRS or other mobile broadband networks.

The improvement of an information communicating technology provides mankind with a rationality of ancient technology, and gave us many benefits as they go beyond time and place. a society that requires information, improving information communicating technology had a revolution over us and is giving us good benefits. The improvement os an information communicating technology gave us benefits for sure. in the other hand, it is giving us a threat also. Important point in a growth of a knowledge information community is to search for a way to make positive function work better and to reduce the bad benefits. They discussed some ways that information society is blocking the growth of a knowledge information community, and the purpose of this essay is to get a step closer to solve these problems.

터널 발파를 원활히 수행하기 위해서는 암반조건에 적합한 합리적인 설계와 정밀한 천공, 정확한 기폭초시가 기본요소로서 이는 현재 국내 터널 설계.시공 기술 및 기자재의 발달로 만족할 만한 성과를 얻을 수 있다. 특히. 터널발파에서 정확한 기폭초시 부여는 굴진율 및 버럭 파쇄율, 굴착예정선 미려도, 잔여 암반 손상도 등의 시공성에서 뿐만 아니라 소음 및 진동 발생율을 좌우하는 환경적인 측면에서 매우 중요한 요소이다. 기폭요소는 최초 도화선을 활용한 공업뇌관에서 전기뇌관, 비전기식뇌관의 순으로 기폭안전성과 정밀성 면에서 눈부신 성장을 이룩하여 왔으며 특히, 90년대 초에 개발되어 전 세계적으로 최근까지 지속적으로 사용량이 급증하고 있는 전자뇌관은 기폭방식에 일대혁신을 이루었다. 전자기폭 시스템은 기존뇌관의 초시를 결정하는 화약성분의 지연요소 대신에 IC board(전자회로)에 의한 Digital timer로 신호를 발생하여 초시를 결정하는 방식이다. 본 논문에서는 국내 최초로 전자기폭시스템을 활용하여 2003년 9원 23일에서 동년 11월 2일까지 강원도 양구 지역의 $\bigcirc\bigcirc$터널에 전자뇌관을 이용한 시험발파를 실시하였고, 발파에 의한 진동 등을 조사하여 그 효율성을 검토하였다. 이를 위해 전자뇌관의 특성과 장점을 최대한 샅리기 위하여 각공을 발파하는 방식, 즉 1지발에 1공을 발파하는 방식을 채택하고 일반 뇌관과 전자뇌관으로 설계를 하여 각각의 발파효율을 비교하여 보았다. 그 결과 발파진동의 경우 기존뇌관을 이용하여 1공씩을 1지발로 발파를 한 경우에는 18~56%의 진동저감 효과가 있었고. 본선 설계에 의해 진행된 발파에 비하여는 최대 70% 이상의 진동저감 효과가 있는 것으로 나타났다.
