본 논문은 2014년 세월호 사고 이후 해양재난사고에 대한 국민들의 경각심이 고조되었으며 해양레저인구증가로 인한 해양사고가 증가되는 상황에서 사고예방 및 해양안전문화 고취를 위한 해양안전교육센터 구축하고자 수요추정을 수행하였다. 특히, 우리나라 대부분의 해양안전체험관과 유사한 체험관들은 대부분 전라, 경기지역에 분포하고 있어 지역 편향을 해소하는 차원에서 동남권 안전센터 구축이 필요한 상황이며 해양레저 및 해양산업의 중심이 영남권에 위치하고 있기 때문에 안전교육센터의 구축의 정책적인 타당성이 있다. 본 논문에서는 해양안전교육센터 수요추정을 중력모형을 활용하여 수행하였으며 사회경제적인 타당성의 근거로서 활용이 가능할 것으로 기대된다.

This study examined the influence and role of college students' career preference type on the decision-making process of career selection, and also analyzed the effect on the confession bias in the process. The data was collected from June 20th to July 9th, 2017. The case analysis method was used for three times over 20 days by interviewing university students in the metropolitan area. The results of the analysis of the data from the study participants show that there are differences in the degree of individuals regardless of the preferred occupation type and career aptitude, but mostly there is a bias toward career and career. Confirmed biased thinking is a phenomenon that is shaped by the psychological and environmental factors of the research participants and that they try to fit themselves into a framework that reflects social awareness. The implication of this study is that the preference type affects the selection of the major, and that confirmation bias is a hindrance to proper employment and a job search. The preference for the individual job type should be properly established. Environment and opportunity should be provided.

꾸준히 증가하고 있는 창업시장에 남성 못지않게 여성의 창업도 증가하고 있다. 여성 창업을 독려하기 위한 다양한 정책도 많지만 남성의 창업 성과에 비해 여성의 창업 성과는 미미하게 나타나고 있다. 중소기업청에서 조사된 창업 현황으로 본다면 남성은 다양한 산업 분야에 창업을 하고 있고 자금투자유치 및 고성장도 이루어지고 있는 반면에 여성은 한정된 산업 분야에 개인자금조달 및 소규모경영형태로 나타나고 있다. 본 연구는 남성과 여성의 창업 형태가 위와 같이 차이가 나는 근본적인 원인을 사회적으로 잠재되어있는 젠더레짐에 영향을 받아 나타나는 것으로 가정하고 실증적인 검증을 하려고 한다. 양성평등 및 차별금지에 관한 교육이 꾸준히 이루어지고 있음에도 뿌리 깊은 젠더편향적인 한국문화적 특성상 그 성-편향적 사고의 틀 안에서 여성 창업에 대하여 평가하고 있다. 여성 창업은 꾸준히 증가되고는 있지만 암묵적으로 방관하는 젠더편향적인 사회 문화를 인식을 개선하지 않는 이상 여성 창업 환경과 그 성과는 앞으로도 크게 나아지지 않을 것이라고 생각 된다. 이에 남성 주류의 창업생태계 안에서 여성 창업에 대한 편견 및 유리천장이 존재하여 그 성장에 한계가 있는 것으로 가정하고 본 연구는 젠더레짐이 여성창업의도에 어떠한 영향을 미치는지 검증해보려고 한다.

The purpose of this study is to investigate the young children's 'more means more' bias and knowledge change process regarding a lever phenomenon, especially the relationship between the weight of an object and the strength of force and between the length of a lever and the strength of force. Subjects, who were presented with the tasks, were eight young children 5 years of age. Major findings were as followings. First, most of the subjects have a 'more means more' bias about the relationship between the weight of an object and the strength of force and between the length of a lever and the strength of force regarding a lever phenomenon. This meant that young children have similar concepts about a lever phenomenon regardless of whether it is right or wrong physically. Second, young children tried to make sure of their knowledge during experiments. They chose the evidence which confirmed their knowledge. But they tried to change their knowledge, when the evidence presented did not correspond to their knowledge. These findings contribute to understanding young children's 'more means more' bias and knowledge change process about a lever phenomenon and can be used in preschool science education programs and curriculums.

Due to the increasing proportion of cloud and remote working environments, various information security incidents are occurring. Insider threats have emerged as a major issue, with cases in which corporate insiders attempting to leak confidential data by accessing it remotely. In response, insider threat detection approaches based on machine learning have been developed. However, existing machine learning methods used to detect insider threats do not take biases and variances into account, which leads to limited performance. In this paper, boosting-type ensemble learning algorithms are applied to verify the performance of malicious insider detection, conduct a close analysis, and even consider the imbalance in datasets to determine the final result. Through experiments, we show that using ensemble learning achieves similar or higher accuracy to other existing malicious insider detection approaches while considering bias-variance tradeoff. The experimental results show that ensemble learning using bagging and boosting methods reached an accuracy of over 98%, which improves malicious insider detection performance by 5.62% compared to the average accuracy of single learning models used.

It is true that many tales delivered in an 'Story-telling' auditorium or theater have not so much exquisite and refined forms as distorted and deteriorated ones. Furthermore, when false interpretations of tale-performers added into the category of the texts of tales, the problems can be made worse. In case of oral folk tales, there can be discordance between the standpoint of a tale-performer and the contents of a tale. This thesis is directly aimed at pointing out the 'Behavior Economics' problems concerned with the reading and interpretation of tales through investigating the missing parts of a text in reading tales. Man's rationality is meant to be confined to bounded rationality. Instead of making best choices, bounded rationality leads consumers to make a decision which they think suffices themselves to the point requiring no more consideration on the given item. It is the very Heuristic that does work in the process of this simplified decision making process. Heuristic utilizes established empirical notion and specific information, and that's why there can be cognitive 'Biases' sometimes leading to inaccurate judgment. As Oral Literature is basically based on heavy guesswork and perceptual biases of general public, it is imperative to contemplate oral literature in the framework of Heuristic of behavior economics. This thesis deals with thinking types and behavioral patterns of the general public in the perspective of heuristic by examining 'Story-tellings' on the basis of personal or public memory. In addition, heuristic involves how to deal with significant but intangible content such as the errors of oral story teller, the deviations of the story, and responses of the audience.

The study was intended to explore the relevance of the variables below, assuming that the intolerance of uncertainty and dichotomous thinking would represent sequential serialized effects in the relationship between perfectionistic self-presentation and social anxiety. The data of this study were collected on questionnaire survey of 252 adult men and women in Seoul using perfectionistic self-presentation scale, social interaction anxiety scale, social phobia scale, intolerance of uncertainty scale and dichotomous thinkingI-30R as index, which results are as follow. First, intolerance of uncertainty and dichotomous thinking showed perfect mediation effects on the relationship between perfectionistic self-presentation and social anxiety. Intolerance of uncertainty and dichotomous thinking were identified as contributing factors to the development and preservation of social anxiety by perfectionistic self-presenters. Second, in the relationship between perfectionistic self-presentation and dichotomous thinking, intolerance of uncertainty showed mediation effect. And in the relationship between intolerance of uncertainty and social anxiety, dichotomous thinking showed mediation effect. This suggested that if tolerance of uncertainty was deficient, it was likely to lead to dichotomous thinking. And a dichotomous thinking has prompted or accelerated negative cognitive biases resulting from intolerance of uncertainty, triggering and deepening social anxiety. Lastly, the limitations of this study and future research direction were suggested.

Motivated reasoning refers to biased reasoning that is affected by motivation to achieve a particular result or goal. In this study, we attempted a theoretical study on motivated reasoning that hinders the development of scientific thinking and empirical study on actual context of motivated reasoning in the research experiences of next-generation Korean researchers in the field of science and technology. To be specific, literature reviews were conducted to explore the psychological meaning of motivated reasoning and its negative impact on scientific thinking and science research. To understand the substantial meaning and context of motivated reasoning in the field of real science and technology research, we conducted in-depth interviews with eight graduate students and one young science and technology researcher. As a result of the literature reviews, we found out that motivated reasoning can interfere with the proper theory and data coordination, which is the core process of scientific thinking at the individual level. At the socio-cultural level, it can lead to cessation of constructing scientific knowledge and it can act as a mechanism in the process of using science for specific socio-cultural beliefs or purposes, thereby hindering the development of science and technology based on rationale and objective scientific thinking. Quantitative analysis with in-depth interview data showed that graduate students and the young researcher's experienced motivated reasoning results in trying to protect prior beliefs, make hasty conclusions, protecting socio-cultural belief or rationalizing decisions made by their community. Their motivated reasoning could become an obstacle in constructing valid science and technology knowledge through appropriate theory and evidence coordination. Based on these findings we discussed science education for improving scientific thinking.

The use of thought experiments has a long history in many disciplines including science. In the field of philosophy, thought experiments have frequently appeared in the pre-existing literature on the contemporary Analytic Philosophy. A thought experiment refers to a synthetic environment where the designer of the experiment-with his or her intuition and imagination-tests common-sense knowledge. It can be understood as a conceptual tool for testing the validity of the common understanding of an issue or a phenomenon. However, we are not certain about the usefulness or efficacy of a thought experiment in knowledge production. The design of a thought experiment is meant to lure readers into believing as intended by the experiment itself. Thus, regardless of the purpose of a thought experiment, many readers who encounter the experiment could feel deceived. In this paper, to analyze the logic of thought experiments and to seek the source of uneasiness the readers and critics may feel about thought experiments, I draw lessons from three renowned thought-experiments: Thomson's 'ailing violinist', Putnam's 'brain in a vat', and Searle's 'Chinese room'. Imaginative thought experiments are usually constructed around a gap between the reality and the knowledge/information at hand. From the three experiments, several lessons can be learned. First, the evidence of the existence of a gap provided via thought experiments can serve as arguments for counterfactual situations. At the same time, the credibility and efficacy of the thought experiments can be damaged as soon as the thought-experiments are carried out with inappropriate and/or murky directions regarding the procedures of the experiment or the background of the study. According to D. R. Hofstadter and D. C. Dennett(1981), the 'knob setting' in a thought experiment can be altered in the middle of a simulation of the experimental condition, and then the implications of the thought experiment change altogether, indicating that an entirely different conclusion can be deduced from thought experiment. Lastly, some pre-suppositions and bias of the experiment designers play a considerable role in the validity and the chances of success of a thought experiment; thus, it is recommended that the experiment-designers refrain from exercising too much of their imagination in order to avoid contaminating the design of the experiment and/or wrongly accepting preconceived/misguided conclusions.

Feminism on the theme of gender equality is emerging as an important issue in the overall Korean culture. Feminism is not only a level of claiming or advocating women's rights, but an essential subject of gaze and thought, not a distorted, artificially portrayed image of women distorted or typified in a story created by men in the past It is a film that explores the problem of the individual's life in society fundamentally. Jun Koeun's movie' 'micro-habitat'(2018) 'expresses a feminist theme that shows a strong self - selection and transcendental thinking in male - oriented stereotypes and inequal social structure. The film, which focuses on the public insight into society and the enhancement of the ideal human being from the viewpoint that the public film should lead the educated enlightenment character that raises the broad insight into the world and lead the mature social culture, I think it will play a big role.
