The importance of classes aiming at enhancing students ability in problem solving and decision making has been being recognized as chances of individual citizen for taking part in social decision making processes. This study was intended to find whether teachers' opinion presentation have effects on students' decision making in a class introducing environmental issues. Total of 6 classes, 202 middle school students have participated in a series of experiments including 4 different environmental issues. Only two issues had been addresses in classes as experimental issues and other two issues not addressed as control issues. For each of the two experimental issues, the teacher researcher applied three different approaches to his students that included positive, negative, or no opinion. The results of this study can be summarized as follows; First, the results showed that students changed their decisions on environmental issues more frequently when dealing with those issues in a class than when not dealing with them. Second, as examining the relationship between patterns in which students make decisions and whether a teacher proposed his opinions or not, it is shown that the rates of students whose opinions is not changed nearly have no difference, while when teachers propose their opinions, it is shown that students who haven't yet chosen their positions easily make their decisions into pros or cons, compared with the opposite case. Third, the results of this study partly supported the third hypothesis that teachers opinion presentation would effect on decision-making of students. It was found that there has been a significant effect in the case of car free day system issue, but no statistically meaningful result in the case of no pets in the national park issue. However, in the issue of car free day system, it seems pretty clear that the students followed the direction of teachers' opinion no matter what it was pros or cons.

이 글은 제주도 에멘 난민 수용에 대한 여론의 추이와 그에 따른 정치적 상황에 주목하면서 시작되었다. 제주도 난민 수용 반대 여론은 난민법의 수정 또는 폐지까지 요구한다. 에멘 난민 수용을 거부하는 입장은 치안과 안전, 문화 마찰, 경제적 이익이라는 측면에서 어느 정도 설득력을 가지지만 전향적인 사회가 견지해야 할 보편적인 가치, 진리적인 가치에는 반한다. 정치적 결정권자가 여론은 살피는 일은 자연스럽고 또한 중요한 일이다. 그러나 아무리 많은 다수의 의견이라 할지라도 정의롭지 않은 여론은 정치적 결정의 토대가 되어서는 안 된다. 본 논문은 그러한 이유와 근거로 여론의 형성과정과 관련 개념들의 그림자를 살펴볼 것이고, 반대로 공동체적 결정이 참고할 수 있는 가치로서 아우구스티누스의 '사랑' 개념과 원리를 검토하고자 한다. 갈등은 불안전과 균열을 초래한다. 공통감이 없으면 균열은 봉합되지 않는다. 본 논문은 이러한 갈등상태가 해소되어야 함을 과제로 삼고 아우구스티누스에게서 혜안을 얻고자 한다.

Decision makers in the service industry must effectively cope with queuing problems, service capacity optimization, service efficiency and service quality problems. This study proposes a computer simulation-enabled MCDM framework that integrates computer simulation analysis, Taguchi method, expert opinion and multiple criteria decision making (MCDM) to assist decision makers in coping with decision problems. In this framework, Taguchi method is adopted to reduce the time required for the simulation experiment. Computer simulation analysis is adopted to obtain useful information for rapid decision-making without interrupting actual production. MCDM is used to select the optimal alternative. The illustrative result is extremely promising.

Nowadays, online word-of-mouth has become a powerful influencer to marketing and sales in business. Opinion mining and sentiment analysis is frequently adopted at market research and business analytics field for analyzing word-of-mouth content. However, there still remain several challengeable areas for 1) sentiment analysis aiming for Korean word-of-mouth content in film market, 2) availability of machine learning models only using linguistic features, 3) effect of the size of the feature set. This study took a sample of 10,000 movie reviews which had posted extremely negative/positive rating in a movie portal site, and conducted sentiment analysis with four machine learning algorithms: naïve Bayesian, decision tree, neural network, and support vector machines. We found neural network and support vector machine produced better accuracy than naïve Bayesian and decision tree on every size of the feature set. Besides, the performance of them was boosting with increasing of the feature set size.

Threat is one special type of communication whereby one conveys opinion, knowledge, or attitude to another with an intention to influence and modify the latter's opinion or behavior. This research aims at identifying the antecedents and the effectiveness of threats applied in the process of purchasing decision-making. The research model integrates constructs derived from the literature of diverse discipline. The framework suggested explains the relative effects of threats, is tested empirically to verify the impacts on the influenced target's opinions and behaviors in buying centers. Data are collected from CAPM's members in Taiwan, and 208 respondents served as targets in the interpersonal relationships. LISREL findings indicate that threats are effective in winning a target's compliance. Additionally, influencing source's characteristics affect the choice of threats more strongly than target characteristics do. The relative ability of dependence on the source to cause manifest influence is even more significant than that of threats. Overall, the results of this study appear consistent with behavioral theories and research.

In a digital economy, users actively express their needs in many ways. Thus, many researchers analyze what users need and whether they are satisfied or not through opinion mining. In addition, they begin to find technology opportunities in heterogeneous technology fields. But they did not connect users' opinion to technology development process, only focused on natural language processing or marketing or manufacturing area. Also, heterogeneous technology fields are focused on fusion technology. Thus, this study suggests a novel approach that is based on sentimental value and can be applied to exploring technology opportunities in heterogeneous fields. Sentimental value is calculated from users' opinion through sLDA. The heterogeneous technology opportunity is explored by patent analysis. This research contributes to suggesting a hybrid methodology through patent and users' opinion. In addition, it can provide managerial efficiency by suggesting base data onto decision making.
