This study develops an the ideal portrait of a human being pursuing in home economics education from a critical science perspective. The practical problem is 'what should the ideal portrait of a human being pursuing in home economics education with a critical science perspective be?' was addressed through a practical reasoning research method with the stages of valued ends, context, alternatives, consequence, and a final plan. The sequential flow of understanding values and contexts established the setting of three valued ends by organizing issues and categorized areas of individuals, families, society, and cultural from a critical science perspective. The ideal portrait of human being was specifically stated, in the self-formation, independent, inter-subjectivity, social participation, and enculturation according to subcategories; in addition, the stated ideal portrait of human being was modified through expert consultations. Alternatives and consequences were reexamined for the validity of the statement and restated as a comprehensive statement of ideal portrait of a human being that included a restatement of the five areas. An ideal portrait of a human being pursuing in home economics education from a critical science perspective was made from alternative ideal portraits of the proposed human being and stated as 'a person who can continually act autonomously in one's life-world.'

The utility of learning techniques in investment analysis has been demonstrated in many areas, ranging from forecasting individual stocks to entire market indexes. To date, however, the application of artificial intelligence to financial forecasting has focused largely on short predictive horizons. Usually the forecast window is a single period ahead; if the input data involve daily observations, the forecast is for one day ahead; if monthly observations, then a month ahead; and so on. Thus far little work has been conducted on the efficacy of long-term prediction involving multiperiod forecasting. This paper examines the impact of alternative procedures for extended prediction using knowledge discovery techniques. One dimension in the study involves temporal granularity: a single jump from the present period to the end of the forecast window versus a web of short-term forecasts involving a sequence of single-period predictions. Another parameter relates to the numerosity of input variables: a technical approach involving only lagged observations of the target variable versus a fundamental approach involving multiple variables. The dual possibilities along each of the granularity and numerosity dimensions entail a total of 4 models. These models are first evaluated using neural networks, then compared against a multi-input jump model using case based reasoning. The computational models are examined in the context of forecasting the S&P 500 index.

In architectural design, the user is one of the most important factors for the design task as well as the standard for evaluating the value of the built environment after its construction. Recently, accidents, such as fires and breakdowns, in huge and complicated buildings have increased the importance of user behavior simulation. The Korean government has tried to establish a regulation for the prevention of accidents in the built environment. This is regarded as a significant step forward for providing a safer and more appropriate environment for users. However, the existing technologies related to analyzing user behavior only simulate simplified situations. Such simulations are not enough to evaluate accurately the designed alternatives because buildings and spaces contain more complicated information than what we have conventionally considered. Thus, we propose that the advanced agent can interact with the architectural context. It can understand not only the physical situation but also how the users affect this situation. In order to realize this, we adopted the concept of affordances as the perceived action possibilities for the simulation environment.

This paper aims to explore the relationship between the quality of the audit and the level of stock return co-movement in the context of the Vietnamese emerging market. The empirical study is designed based on the quatitative method and deductive approach. The panel dataset includes 256 listed firms from different industries,with 1115 firm-year observations on Ho Chi Minh City Stock Exchange for the period from 2014 to 2018. In the research, we built the econometric regression model, using stock return synchronicity and audit quality as the dependent and independent variable, respectively. Some control variables are also added to the econometric regression models as they are well-documented in prior research to have an effect on stock price synchronicity. To improve the accuracy of the regression coefficients, beside the Ordinary Least Squares, we employ the Random Effects Model and the Fixed Effects Model for better statistical analysis of panel data set. The results show that the quality of the audit is positively correlated to stock price synchronicity. This finding suggests that stock returns of companies with higher quality of the audit are more synchronous with the market. Results for other control variables also support our reasoning for the main findings.

This study aimed to identify some tendencies when college students got to making a decision on socioscientific issues. The guiding research questions were as follows. First, what are college students' tendencies in terms of their moral reactions and attitudes toward SSI when they get to making a decision? And second, how do their own circumstances, personalities, and values play a role in shaping their stance on SSI? Data was collected by individual interviews with thirty college students. The results indicated that most participants immediately brought in their own values, worldviews, and feelings in implicit or explicit ways when talking about SSI. Their reactions were influenced by their backgrounds such as religion, and family background, personality, past experiences, personal interests, and prior knowledge. In addition, the responses of the participants presented some tendencies in their decision-making process. The tendencies can be categorized into 1) bringing in personal values without further engagement, 2) being confused with incompatible values, 3) being overwhelmed by too many aspects to consider, and 4) trying to be detached from the issues.

In the wake of several high-profile corporate accounting scandals, there has been evidence that companies are more eager to hire Chief Executive Officers (CEOs) with an accounting background. This signals that CEOs with an accounting background are recognized and trusted by the corporate world to boost the quality of financial reporting of a company. If it is so, in the context of combating the earnings management, hiring CEOs with an accounting background (being a conservative accounting practitioner), could become one of the effective internal corporate governance mechanisms (CGM) to bring down the earnings management activities. This study attempts to provide insight into the level of conservatism of the CEO with an accounting background. Following Basu (1997) and Khan and Watt (2009), the firm-year measure of conservatism (C_Score) was obtained, which later was associated with the accounting education of the CEO to determine their relationship. As expected, CEOs with accounting background exhibit a higher level of moral reasoning than their non - accounting educated counterparts. The finding of this study is useful to persuade the policymaker to consider lifting the trend of hiring a CEO with an accounting background as one of the best practices that the companies can work out to lessen earnings management activities.

Currently, museums and architectural heritage provide augmented user experiences by incorporating various media technologies. They still, however, suffer from the limitation of entertainment-based and the provision of location-based simple and repetitive contents. In addition, while acting as a key medium of experience for architectural heritage, the concept of space is not properly reflected in current services. The purpose of this study is to design user space experience considering such characteristics of architectural heritage. The spatial experience content and content production platform are defined. This software platform creates content that enhances the experience of the place by giving a context-based digital data associated with space and objects. The spatial experience content is designed as a series of experience sequences. The composition of the sequence borrows the method of film and narrative which segment and connect consecutive experiences on a scene basis considering user's detailed spatial experience. Therefore, content components can be combined and reproduced in various types. Augmented contents were extracted by using rule-based reasoning function of ontology at the moment. As a practical example of architectural heritage, the Seokjojeon Hall is used to reveal a spatial experience scenario.

최근 전 세계적인 원전 설비의 수요 증가로 원자력 전략물자 취급의 중요성이 높아지는 가운데, 국외 수출을 위한 원전 관련 물품 및 기술의 신청 또한 급증하는 추세이다. 전략물자 사전판정 업무는 통상 원자력 물자 관리에 해박한 전문가의 경험 및 지식에 근거하여 수행되어 왔지만, 급증하는 수요에 상응하는 전문 인력의 공급이 부족한 실정이다. 이러한 문제를 극복하기 위하여, 본 연구진은 전략물자 수출 통제를 위한 사례 기반 지능형 수출 통제 시스템을 설계 및 개발하였다. 이 시스템은 현장 전문가의 전담 업무이던 신규 사례에 대한 전략물자 사전판정 과정 업무의 주요 맥락을 자동화 하여 전문가 및 관계 기관이 감당해야 할 업무 부담을 줄이며, 빠르고 정확한 판정을 돕는 의사결정 지원 시스템의 역할을 맡는다. 개발된 시스템은 사례 기반 추론 (Case Based Reasoning) 방식에 기반을 두어 설계되었는데, 이는 과거 사례의 특성을 활용하여 신규 사례의 해법을 유추하는 추론 방법이다. 본 연구에서는 자연어로 작성된 전자문서 처리에 널리 사용되는 텍스트 마이닝 분석 기법을 원자력 분야에 특화된 형태로 응용하여 전략물자 수출통제 시스템을 설계하였다. 시스템 설계의 근거로 선행 연구에서 제안된 반자동식 핵심어 추출 방안의 성능을 보다 엄밀히 검증하였고, 추출된 핵심어로 신규 사례와 유사한 과거 사례를 추출하는 알고리즘을 제안하였다. 제안된 방안은 텍스트 마이닝 분야의 TF-IDF 방법 및 코사인 유사도 점수를 활용한 결과(${\alpha}$)와 원자력 분야에서 통용되는 개념적 지식을 계통으로 분류하여 도출한 결과(${\beta}$)를 조합하여 최종 결과 (${\gamma}$) 를 생성하게 된다. 세부 요소 기술의 성능 검증은 임상 데이터를 활용한 실험 및 실무 전문가의 의견수렴을 통해 이루어졌다. 개발된 시스템은 사전판정 전문 인력을 다수 양성하는 데 드는 비용을 절감하는 데 일조할 것이며, 지식서비스 산업의 의미 있는 응용 사례로서 관련 산업의 성장에 기여할 수 있을 것으로 보인다.
