During the diagnostic process of the various oral and maxillofacial lesions, we should consider the following: 'When should we order diagnostic tests? What tests should be ordered? How should we interpret the results clinically? And how should we use this frequently imperfect information to make optimal medical decisions?' For the clinicians to make proper judgement, several decision making tools are suggested. This article discusses the concept of the diagnostic accuracy (sensitivity and specificity values) with several decision making tools such as decision matrix, ROC analysis and Bayesian analysis. The article also explain the introductory concept of ORAD program.

This paper presents a method of decision on where bus splitting is needed to reduce fault current level of power systems and to satisfy the fault current constraints. The method employs a modified fault current constrained optimal power flow (FCC-OPF) with X variables for the candidate locations of splitting and for decision making on whether to split or not, it adopts soft-discretization by augmenting inversed U-shaped penalty terms. Also, this paper discusses the procedure on the adequate selection of bus splitting locations based on the results of the modified FCC-OPF, to reduce the total number of the actions taken.

The problem of decision making under imprecise environments are widely spread in real life decision situations. We present a method of object recognition from imprecise multi observer data, which extends the work of Roy and Maji [J Compu. Appl. Math. 203(2007) 412-418] to generalized intuitionistic fuzzy soft set theory. The method involves the construction of a comparison table from a generalized intuitionistic fuzzy soft set in a parametric sense for decision making.

The development of mobile applications is fast in recent years. However, nearly all applications are for messaging, financial, locating services based on simple interactions with mobile users because of the limited screen size, narrow network bandwidth, and low computing power. Processing an algorithm for supporting a group decision process on mobile devices becomes impossible. In this paper, we introduce the mobile-oriented simple interactive procedure for support a group decision making process. The interactive procedure is developed for multiple objective linear programming problems to help the group select a compromising solution in the mobile Internet environment. Our procedure lessens the burden of group decision makers, which is one of necessary conditions of the mobile environment. Only the partial weak order preferences of variables and objectives from group decision makers are enough for searching the best compromising solution. The methodology is designed to avoid any assumption about the shape or existence of the decision makers's utility function. For the purpose of the experimental study of the procedure, we developed a group decision support system in the mobile Internet environment, MOBIGSS　and applied to an allocation problem of investor assets.

Purpose: This study aimed to explore and understand the experience of decision making among women undergoing or forgoing selective fetal reduction who have higher-order multiple pregnancies through assisted reproductive techniques. Methods: A qualitative study was conducted from August 1, to October 30, 2013. Eight participants were interviewed and the interviews were audio-recorded and transcribed verbatim. Six persons participated in in-depth interviews in person and two participated over the telephone. A thematic analysis was conducted. Results: Four themes were identified and carefully named: Confusion after higher-order multiple pregnancy; Obstacles to choice: Uncertain safety; Weighing between reality and ideality and; Influences of medical professionals. Conclusion: The results demonstrated a wide range of factors considered by women when making decisions about selective fetal reduction, and mothers' feelings of conflict and distress in the decision-making process. The results suggest that it is important for nurses to provide emotional support and consolation, in addition to sufficient information. These findings will help nurses improve their counseling techniques by understanding the situation of infertile couples.

Decision models are an attempt to reduce uncertainty in the decision making process. The models describe the relationships of variables and given proper input data generate solutions to managerial problems. These solutions may not be answers to the problems for one of two reasons. First, the data input into the model may not be consistant with the underlying assumptions of the model being used. Frequently parameters are assumed to be deterministic when in fact they are probabilistic in nature. The second failure is that often the decision maker recognizes that the data available are not appropriate for the model being used and begins to collect the required data. By the time these data has been compiled the solution is no longer an answer to the problem. This relates to the timeliness of decision making. The authors point out throught the use of an illustrative problem that stocastic models are well developed and that they do not suffer from any lack of mathematical exactiness. The primary problem is that generally accepted procedures for data generation are historical in nature and not relevant for probabilistic decision models. The authors advocate that management information system designers and accountants must become more familiar with these decision models and the input data required for their effective implementation. This will provide these professionals with the background necessary to generate data in a form that makes it relevant and timely for the decision making process.

그간 크라우드펀딩에 대한 연구는 주로 크라우드펀딩의 도입을 위한 방안, 정책에 주로 관심을 가졌으나, 본 연구는 투자의사결정기준을 분류하고 각 요인의 중요성을 제시하여 크라우드펀딩 투자자들에게 실질적으로 도움을 줄 수 있는 연구결과를 도출해 내었다. 연구결과에 따르면 (1) 크라우드펀딩 투자자는 비즈니스 모델을 보다 객관적으로 판단하기 위한 방안으로 기업의 유형자원을 가장 중요한 기준으로 고려하고 (2) 기업의 경영능력에는 관심이 많지만, 비즈니스 모델에 대한 창의성은 크게 관심을 가지고 있지 않고 있음을 확인하였다. 이 연구결과는 크라우드펀딩이 계량적 투자기준을 통해 투자의사를 결정할 수 있고, 창의적인 비즈니스 모델에 대한 건전한 투자라는 인식이 형성될 수 있는 환경이 조성되어야만 하며, 신규기업도 창의적인 비즈니스 모델을 통해 기존기업과 건전한 경쟁을 할 수 있는 제도적 장치가 필요하다는 점을 시사한다.

Consumers' price related response in the clothing purchase decision-making process includes their expectation of price, price perception, attitude toward price and consequent behaviors. The purposes of this research are to systematically organize consumers' price related responses in the clothing purchase decision-making process, and to explain the effect of price on their purchasing. The qualitative research including shopping observation and in-depth interview was conducted. The result identified stages that showed different price related responses in clothing purchase decision-making process, and clarified each stage's characteristics. In the internal search stage, consumers recalled price information from memory and had a specific expectation about the price. This set a direction for the external search. In the external search stage, consumers selected brands or stores by a non-compensatory evaluating with an expectation of the price, and narrowed these down to several determinant alternatives by actively evaluating the products. In case a sufficient amount of price information was not recalled, the consumer established reference price through the external search. Finally, in the purchasing stage, consumers evaluated the determinant alternatives based on their compensatory evaluation. When perception of price was negative, consumers evaluate price combined with the higher criteria of clothing benefits, such as symbolic value and usability. The research is expected to contribute to predicting consumers' responses to price, and to establishing an effective pricing strategy.

본 연구는 조리전공 대학생들의 셀프리더십이 진로결정 자기효능감과 진로준비행동과의 영향관계를 분석하기 위해 설문조사를 실시하였다. 수집된 data는 SPSS 16.0 Version 통계 패키지 프로그램을 활용하여, 빈도분석, 요인분석, 신뢰도분석, 다중회귀분석을 실시하였고, 다양한 결과들을 도출하였다. 첫째, 모든 셀프리더십의 하위요인(행동준비전략, 자연보상 및 건설적 사고전략)은 진로결정 자기효능감의 하위요인(직업정보, 목표설정, 계획수립, 문제해결, 자기평가)에 정(+)의 영향을 미치는 것으로 나타났다. 둘째, 모든 셀프리더십 하위요인은 진로준비행동 하위요인(진로탐색활동, 목표달성활동)에 정(+) 영향을 미치는 것으로 나타났다. 결과적으로, 조리전공 대학생들의 셀프리더십의 강화는 진로결정 자기효능감과 진로준비행동으로 발전에 매우 중요하다는 것을 확인하였다.
