  • Grinding is used for machining high precision parts with high additional value. However, the grinding operation needs high skill and long experience of an operator because of a lack of the scientific knowledge and engineering principles. Also, the wheel and grinding conditions affect grinding results. For these reasons, it is difficult to construct computer integrated manufacturing system(CIMA). Therefore, it is necessary for Expert System to be informed of qualitative knowledge of grinding expert's skills and experiences. In this research, the Grinding Expert System is constructed by Fuzzy Decision Making Algorithm. Using this system, unskilled workers will be able to use the knowledge and experience of an expert.

  • Objective : Age is a strong predictor of mortality in traumatic brain injuries. A surgical decision making is difficult especially for the elderly patients with severe head injuries. We studied so-called 'withholding a life-saving surgery' over a two year period at a university hospital. Methods : We collected data from 227 elderly patients. In 35 patients with Glasgow Coma Score 3--8, 28 patients had lesions that required operation. A life-saving surgery was withheld in 15 patients either by doctors and/or the families (Group A). Surgery was performed in 13 patients (Group B). We retrospectively examined the medical records and radiological findings of these 28 patients. We calculated the predicted probability of 6 month mortality (IPM) and 6 month unfavorable outcome (IPU) to compare the result of decision by the International Mission for Prognosis and Analysis of Clinical Trials in TBI (IMPACT) calculator. Results : Types of the mass lesion did not affect on the surgical decision making. None of the motor score 1 underwent surgery, while all patients with reactive pupils underwent surgery. Causes of injury or episodes of hypoxia/hypotension might have affected on the decision making, however, their role was not distinct. All patients in the group A died. In the group B, the outcome was unfavorable in 11 of 13 patients. Patients with high IPM or IPU were more common in group A than group B. Wrong decisions brought futile cares. Conclusion : Ethical training and developing decision-making skills are necessary including shared decision making.

  • 많은 엔젤 투자자들이 초기단계기업에 투자하는 것을 주저하고 있다. 초기단계기업은 대부분 매출이 없고, 개발단계이거나 시장진입초기단계인 경우가 많아서 기업 가치를 정량적으로 평가할 수 없기 때문이다. 따라서 엔젤 투자자들이 기업을 평가하고 투자의사를 결정하는 경우 기업가의 성향에 의존 할 수밖에 없는 경우가 많다. 이에 본 연구는 엔젤 투자자의 투자의사결정요인에 영향을 주는 기업가적 특성의 요인과 그 중요도를 도출하였다. 연구방법은 엔젤 투자클럽, 벤처캐피털리스트, 기업 대표 및 임원 등의 엔젤 투자자 전문가 그룹 20인을 선정하여 델파이 기법(Delphi Technique)에 따라 설문조사를 실시하였다. 3차에 걸친 조사 결과 투자의사결정요인 중에서 기업가적 특성에 해당하는 요인으로 신뢰성, 위험감수성, 열정, 인내력, 진실성, 리더십, 창업경험, 조직관리능력, 혁신성, 인맥(네트워크)의 10개의 요소들을 도출하였다. 또한 도출된 기업가적 특성 요소의 중요도를 분석하기 위하여 AHP(Analytic Hierarchy Process) 이론에 근거하여 각 요소에 대한 쌍대비교(Pair-wise Comparison)를 통하여, 그 중요도를 분석한 결과 신뢰성(18.1%), 진실성(15.9%), 리더십(11.7%), 조직관리능력(10.0%), 인맥(네트워크)(9.5%), 열정(9.1%), 인내력(8.4%), 혁신성(8.1%), 창업경험(5.3%), 위험감수성(3.9%)의 순으로 나타났다. 본 연구는 의의는 투자자의 투자 의사 결정에 영향을 주는 요인들 중에서 초기 단계의 기업에 가장 큰 영향 요인이라 할 수 있는 기업가적 특성 요인을 도출하여 중요도를 비교함으로써 엔젤 투자의 불확실성으로 인하여 생기는 한계를 다소나마 줄이고, 엔젤 투자자의 판단에 도움을 줄 수 있다는 점이다.

  • Recently, RoboCup soccer simulation has been regarded as a good benchmark problem for multiagent researches. Soccer agents have to make decision based on visual and auditory information, which are sent from the soccer server. In order to develop a strong team, we have to design decision-making process of each player agent. However, it is very difficult for us to design the decision-making processes in detail, because we don't know what actions of each player are effective for the team. In this paper, we attempt to apply co-evolutionary method, which is one type of analogies of evolution, to improve the team play. Agents have hand coded basic skills, which include dribble, shoot, pass etc. Agents already can play autonomously and independently. Individual agent skills are characterized by some parameters. By coevolving teams with these parameters, we obtained relatively interesting teams, in which players behave cooperatively in order to win the soccer game. From some experiments, we discuss what teams are evolved.

  • The aim of this descriptive cross-sectional study was determine the effect of critical thinking and clinical decision-making on ethical dilemmas. A survey of dental hygienists residing in Busan and South Gyeongsang, Korea was conducted using convenience sampling between September and December, 2013. A total of 153 responses were used in the final analysis. Data analysis and structural equation modeling were performed with IBM SPSS Statistics(version 21.0) and AMOS(version 18.0) programs. A negative(-) correlation coefficient(-0.37) was observed between critical thinking and ethical dilemmas on statistical analysis, i.e., higher critical thinking led to less ethical dilemmas(p=0.024, CR=-2.264). The values from the structural equation model were ${\chi}^2=98.124$ df=66, GFI=0.919, AGFI=0.871, and RMSEA=0.057. This study proposed a theoretical model in which critical thinking, ethical values, and decision-making skills should be firmly established to effectively respond to specific situations, such as ethical dilemmas, and that greater tendencies for critical thinking led to less ethical dilemmas, thereby demonstrating a negative(-) correlation between the two parameters.

  • The purpose of this study is to prepare basic data to help college students adapt to college life by grasping the effects of mentoring skills, self-concept, career decision-making self-efficacy, and major satisfaction on college life adaptation. To achieve the purpose of the study, data were collected from January 17 to January 27, 2024, targeting college students from one university in C city located in G-do. The survey was conducted online. As a result of the study, the mentoring function of the subjects averaged 4.11 points (out of 5 points), the self-concept was 4.29 points (out of 5 points), the career decision-making self-efficacy was 4.04 points (out of 5 points), the major satisfaction was 4.45 points (out of 5 points), and the college life adaptation was 3.91 points (out of 5 points). The factor that most influenced the subject's adaptation to college life was career decision-making self-efficacy, followed by self-concept, mentoring function, and major-art field. The explanatory power of the model was 70.2%. Specifically, the higher the career decision-making self-efficacy, the higher the self-concept, and the higher the mentoring function, the higher the adaptation to college life. Educational intervention programs (non-curricular programs) are needed to adapt to college life for college students, and subsequent studies need to examine the effects of the developed programs.

  • Organizational personnel must have well-developed interpersonal skills to deal with the different stakeholders and departments, to work at different levels in the hierarchy, and to meet varying performance requirements. Many leadership development and mentoring programs are designed to expose students as well as construction professionals to contemporary leadership techniques and skills. Leadership skills generally separate into three decision-making styles with varying degrees: 1) Autocratic, 2) Participate, and 3) Free-rein. This paper describes the study of leadership styles among 174 construction professionals and addresses the most appropriate leadership style for a project executive and a project manager in relation to compare with the characteristic leadership style and job functions. The study supports the growing importance of leadership skills as a component of managerial functions and provides a benchmark to identify a dominant leadership skill for a specific managerial position.

  • In real-life scenarios, we may have to deal with real numbers or numbers in intervals or a combination of both to solve multi-criteria decision-making (MCDM) problems. Also, we may come across a situation where we must combine this interval and actual number membership values into a single real number. The most significant factor in combining these membership values into a single value is by using aggregation operators or scoring algorithms. To overcome such a situation, we suggest the cubic hypersoft set (CHSS) concept as a workaround. Ultimately, this makes it simple for the decision-maker to obtain information without misconceptions. The primary aim of this study is to establish some operational laws for the cubic hypersoft set, present the fundamental properties of aggregation operators and propose an algorithm by using the technique of order of preference by similarity to the ideal solution (TOPSIS) technique based on correlation coefficients to analyze the stress-coping skills of workers.

  • This research aims to examine the model of investor herding behavior in making investment decisions in the Indonesian capital market, which is influenced by social and information impacting on the value of the Book Value Per Share (BVPS). The latest stock market conditions show that most investors make the same error pattern in making investment decisions that result in losses. The experiment involves two independent variables, namely, information about BVPS and social influence. This study used a 2×2 factorial design laboratory experimental method. Data collection was carried out through treatment of a sample of 100 individual investors listed on the Indonesia Stock Exchange. Univariate Two-Way Analysis of Variance (ANOVA) statistical tool was used to test the independent variable on the dependent variable. Research results showed that the social influence originating from expert investors is more influential than the Book Value Per Share (BVPS) information on the behavior of herding investors in making investment decisions. These findings suggest that investors know their psychological factors, thereby increasing self-control and investment analysis skills. Further research can use psychological bias and other indicators of accounting relevant information such as Earning Per Share (EPS) to test herding behavior in investment decision making in the capital market.
