This study investigated the factors that influence the attitude, trust, and acceptance toward the North Korean residents by South Koreans. Three hundred and ninety-two South Koreans, including 222 with no contact experience with North Korean residents and 170 with contact experience, answered a questionnaire. The experience group included police officers who provide protection and settlement service, labor counsellors, social workers, church people, college classmates and tutors, and teachers in alternative schools for North Korean youths. The results indicated that protecting police officers have highly negative attitudes in both cognitive and affective dimensions and also show low trust and acceptance. Teachers in alternative schools, on the other hand, were found to have both positive and negative cognitive evaluations of North Korean residents, but still maintained positive affect and high trust and acceptance. People with no contact experience had negative affect along with pity, and showed medium level trust and acceptance. The distinctive difference between the police officers and teachers were attributed to the individual characteristics such as authoritarian personality and uncertainty avoidance rather than to the frequency or depth of contact. The most important determinant of trust and acceptance were found to be the affective component. The implications of these findings on the selection and training of interface personnel and peace education were discussed.

Grounded in the prior literatures on acceptance and diffusion of IT and innovation in the level of organization research, 3 major constructional factors such as Motivation, IT resistance, and IT change management were investigated to suggest propositions from 15 multi-cases of PLM from 6 different companies in Automotive OEMs and suppliers, and we posited that the diffusion is continued only when motivation is stronger enough to overcome IT resistance as a fundamental finding and basis of this research on PLM acceptance and diffusion. The Motivation was found to be initiated and categorized from three different factors such as environmental factors, organizational factors, and technological factors, providing key propositions for further research: (1)The Automotive suppliers, contrary to OEM, are affected more by the demand of inter-connectivity as an environmental factor, while the other factors are similarly influencing to them, (2)The big organizations are influenced more by the champion, while the small organizations get influenced more by leader. (3)When the trend, inter-connectivity and complexity get stronger, the motivation gets more strongly influenced by the perceived benefit in the technological context. Regarding Change management we suggests IT change management is supportive to overcome IT resistance and also to enforce Motivation, and the critical mass exists differently according to the market maturity adopted, and more market matured technology has lower critical mass, implies less requirement of IT change management than less market matured technology.

The basic assumption of analytical Dynamic Traffic Assignment models is that traffic demand and network conditions are known as a priori and unchanging during the whole planning horizon. This assumption may not be realistic in the practical traffic situation because traffic demand and network conditions nay vary from time to time. The rolling horizon implementation recognizes a fact : The Prediction of origin-destination(OD) matrices and network conditions is usually more accurate in a short period of time, while further into the whole horizon there exists a substantial uncertainty. In the rolling horizon implementation, therefore, rather than assuming time-dependent OD matrices and network conditions are known at the beginning of the horizon, it is assumed that the deterministic information of OD and traffic conditions for a short period are possessed, whereas information beyond this short period will not be available until the time rolls forward. This paper introduces rolling horizon implementation to enable a multi-class analytical DTA model to respond operationally to dynamic variations of both traffic demand and network conditions. In the paper, implementation procedure is discussed in detail, and practical solutions for some raised issues of 1) unfinished trips and 2) rerouting strategy of these trips, are proposed. Computational examples and results are presented and analyzed.

The purpose of this study is to search for the factors that influence students' understanding of the nature of science through the experience of the cognitive processes of authentic open inquiries. The freshmen of a science high school practiced authentic open inquiries reflecting epistemological characteristics of authentic science. The case study was conducted with four focus students who were successful or unsuccessful at learning the nature of science during the authentic open inquiry activity. Questions that the focus students asked during the inquiries as well as students' answers to pre- and post-VNOS (C type) were analysed, and then elaborated in the semi-structured interview. The findings suggest that open inquiry activities provide the inquiry contexts that help science high school students to understand the nature of science, and that the characteristics of students' cognition influence the understanding of the nature of science. For instance, designing experiments with their own research questions had an influence on the students' understanding about the scientific methods and the diversity of research types, and drawing conclusions from their own data made students experience scientific reasoning. In addition, the experience of collecting anomalous data helped students to understand the role of inferences in generating scientific knowledge and the creative nature of scientific knowledge. In this inquiry context, the reflective thinking that came from proactive discussion among students, made students think about the validity of the designing experiments and interpreting data, and helped them to understand the uncertain nature of reasoning and the diverse nature of scientific methods. Moreover, divergent thinking linked to analogical thinking helped students to understand the creative nature of science.

The purpose of this study is to explore the effect of perceived job insecurity on job crafting behaviors among employees from two different cultures: Jamaica and South Korea. Growth needs strength was also examined as a moderating variable on the job insecurity/job crafting relationship. This study collected 102 data samples from working individuals from Jamaica and 98 from South Korea. The Exploratory Factor Analysis (EFA) and the hierarchical regression analysis were used in order to analyze the data. Statistical analysis was performed using SPSS 24.0. Our research results indicated that perceived job insecurity has a significant effect on employees job crafting behaviors. The relationship between perceived job insecurity and job crafting behaviors differs based on culture. In addition, employees growth need strength moderates the relationship between the two variables. Although this study has some limitations, it contributed to the stress-coping literature by showing that individuals will engage in coping behaviors when they perceived job insecurity in the organization. In addition, culture and individual drive or need for growth plays an important role in how individuals cope with perceived stress or uncertainty.

Successor representation (SR) is a model of human reinforcement learning (RL) mimicking the underlying mechanism of hippocampal cells constructing cognitive maps. SR utilizes these learned features to adaptively respond to the frequent reward changes. In this paper, we evaluated the performance of SR under the context where changes in latent variables of environments trigger the reward structure changes. For a benchmark test, we adopted SR-Dyna, an integration of SR into goal-driven Dyna RL algorithm in the 2-stage Markov Decision Task (MDT) in which we can intentionally manipulate the latent variables - state transition uncertainty and goal-condition. To precisely investigate the characteristics of SR, we conducted the experiments while controlling each latent variable that affects the changes in reward structure. Evaluation results showed that SR-Dyna could learn to respond to the reward changes in relation to the changes in latent variables, but could not learn rapidly in that situation. This brings about the necessity to build more robust RL models that can rapidly learn to respond to the frequent changes in the environment in which latent variables and reward structure change at the same time.

The disposal facility in Gyeongju is planning to dispose of 800,000 packages of low- and intermediate- level radioactive waste. This facility will be developed as a complex disposal facility that has various types of disposal facilities and accompanying management. In this study, based on the comprehensive development plan of the disposal facility, a preliminary post-closure safety assessment is performed to predict the phase development of the total capacity for the 800,000 packages to be disposed of at the site. The results for each scenario meet the performance target of the disposal facility. The assessment revealed that there is a significant impact of the inventory of intermediate-level radionuclide waste on the safety evaluation. Due to this finding, we introduce a disposal limit value for intermediate-level radioactive waste. With stepwise development of safety case, this development plan will increase the safety of disposal facilities by reducing uncertainties within the future development of the underground silo disposal facilities.

The importance of technological innovation orientation, which denotes the firm's general direction of thought toward steadily pursuing and promoting technological innovation in the long run for its viability and competitiveness, is on the rise. Although the technological innovation orientation has conceptually and practically important implications for securing the firm's sustainable competitive advantage, to date there has been limited research systematically analyzing the role of the technological innovation orientation for the firm's successful technological innovation and performance. Recognizing such deficiency in previous research regarding technological innovation orientation, this study selected internal and external critical factors which might affect the technological innovation orientation, and proposed and empirically examined a research model and hypotheses demonstrating the contingency relationships among the antecedent factors, technological innovation orientation and technological innovation performance. In the proposed research model, the selected antecedents of technological innovation orientation included two internal factors of CEO's technical-function experience and cross-functional integration and two external factors of environmental uncertainty and intensity of competition, and eventually it was suggested that these antecedent factors affected the firm's technological innovation performance via the technological innovation orientation. In addition, the research model suggested that the two environmental factors of environmental uncertainty and intensity of competition had a positive moderation effect on the relationship between technological innovation orientation and technological innovation performance. Analysis of data on sample of 86 Korean IT SMEs showed that CEO's technical-function experience, cross-functional integration and environmental uncertainty had a positive impact on the firm's technological innovation orientation and that the technological innovation orientation positively influenced the firm's technological innovation performance. The results also revealed that environmental uncertainty positively moderated the relationship between the firm's technological innovation orientation and technological innovation performance. The theoretical and practical implications for the results of this study were discussed.

EU's future frontier remains indefinite but it is directly linked to the principle of entry into the EU. EU has been defining that the 'european nation' sharing with a EU's value and norms can enter into the EU. If so, what is the criteria of EU? The criterion of 'european nation' will be a theoretical basis of an estimation of the EU's future frontier. However, the future frontier based on the geography, the culture and the intension of nation is only the potential frontier. It will be changed by the political decision makers' negotiation and power. EU's enlargement policy is one of means to retention of the international power in the situation that a few nations gradually dominate the world. Therefore the EU's frontier will be continually changed and created by the EU's political adventure.

우리가 어떠한 상황에서 불안해진다는 것은 다가올 미래에 대해 확실하게 준비할 수 없다는 사실에 근거합니다. 수많은 선각자와 학자들은 모두들 이러한 불확실성으로 인한 위험 요소들을 확실하게 밝히고자하며 이로 인해 우리로 하여금 더욱 과학적으로 상황을 대처하고 극복하게 하려 합니다. 아시아 지역의 호텔관광시장에 대해 이곳에서 논의되는 것은 과거와 현재 그리고 미래를 넘나들며 현재 이 시장에서 벌어지는 새로운 경향을 파악하고 파악된 자료를 통해 도전과 위험요소를 인지케하는 내용들입니다. 과거는 현재의 원인이 될 수 있고 과거의 흔적은 내일의 같은 형태의 현상이 될 수 있다고 보기에 우리는 미래의 시장을 예측하려 할 때 과거를 검증하고 현재를 숙독해야 하는 것입니다. 과거 속에서 우리는 한때 우리 시장의 고객들이 사회적 성공의 표시로 여행을 즐겼으며, 그것이 전쟁 등과 같은 힘든 시절을 보내면서 휴식과 교육을 목표로 여행을 즐기던 시절이 있었고, 이것이 다시 최근에 들어 고객들의 자기충족과 자아실현의 방법으로 여행을 즐기고 있음을 감지할 수 있습니다. 이러한 경향들의 연장선상에서 우리의 호텔시장은 호텔이 고도로 품격화된 개인적인 서비스를 제공하게 될 것이고, 발달된 정보기술력으로 인해 편리하게 자산관리를 할 수 있고, 쉽게 접근이 가능한 투자자본으로 인해 소유주의 형태가 다국적으로 다각화되는 결과를 낳게 될 것이고, 수많은 패턴들이 존재하지만 기술력의 혁신으로 인해 이를 통한 새로운 상품과 서비스의 개발이 가장 두드러지는 시장이 될 것이 분명합니다. 관광시장에서는 크게 두 영역으로 분리해서 본다면, 하나는 새로운 형태의 고객이고 또 하나는 관광이란 것이 거리를 요하는 것이기에 이를 극복하고자 하는 기술력을 동원한 새로운 형태의 관광체험이라 할 수 있습니다. 새로운 형태의 고객은 보다 자유롭고 의사표현이 열려있는 고객이며 이들은 각자의 자아실현과 충족을 위해 끊임없이 새로운 여행 목적지를 찾는 고객이며, 복잡하지 않고 단순한 형태의 상품과 서비스를 요하며 그들은 또한 시작에서 마무리까지 완성된 서비스를 추구하는 고객이 될 것입니다. 거리를 초월하는 기술력의 발달로 고객은 원거리에서 자기자신의 여행 진행 전부를 쉽게 컨트롤 할 수 있게 되고 특히 가상 현실실현에 대한 기술력은 멀리서도 원거리의 여행 체험을 실제와 버금가게, 그리고 현실에서 겪어야 하는 일체의 장애 없이 체득할 수 있게되는 상황을 고객 앞에 내놓게 될 것입니다. 우리는 지금 새로이 중흥하려 노력하는 아시아의 주요 국가의 호텔관광산업을 의미 있게 짚어보고 내일을 함께 준비하고 있습니다. 여기에 논의되어진 이슈가 아니더라도 우리는 그것들을 새로운 시각에서 검증하고 분석하여 새로이 전개되는 미래의 아시아 호텔관광산업을 함께 준비해야 할 줄 믿습니다.
