The effects of goal setting in the context of Multiple Criteria Making (MCDM) are classified into two types : internal and external. In the internal models, the impact of the changed goal is limited only to the other goals in MCDM model. By contrast, in the external models, the impact is limited to the factors not included in the MCDM model. In fact, most real world examples of goal setting have the nature of mixed models. To assist in the goal setting process, the framework named Goal Setting Support (GSS) is developed. The GSS helps decision-makers for mixed models to 1) make internal trade-offs in a way that guarantees non-dominancy after the trade-ofs, and 2) evaluate achieved goals systematically. The GSS can be used in creating Decision Support Systems that will allow interactive goal setting.

홍수기 다목적댐 운영의 목적은 홍수조절용량을 최대한 이용하여 하류 주요 지점의 첨두홍수량을 저감시키거나, 계획홍수량을 초과하지 않도록 방류량과 방류시점을 조절함으로써 홍수 피해규모를 최소화하는 것이다. 본 연구에서는 홍수기 다목적댐 운영에서 다목적 최적화의 한 형태인 goal programming의 적용성을 검토하였다. 실제 강우사상을 이용하여 단일저수지 운영과 저수지 연계운영을 실시하였다. 단일 저수지 운영을 적용하기 위한 시험유역으로는 충주댐 유역을 선정하였고 저수지 연계운영을 적용하기 위한 시험유역으로는 안동댐과 임하댐 유역을 선정하였다. goal programming의 결과 분석을 위해 저수지 모의운영 모형인 HEC-5 모형의 결과와 비교, 분석하였다. goal programming을 이용할 경우 HEC-5 운영결과보다 안정적인 운영결과를 얻을 수 있었다. goal programming을 이용한 최적화 운영의 경우 전구간의 유입량을 알고 있다는 점에서 실제 저수지 운영과는 차이가 있다. 그러나 적절한 제약조건을 적용하고 홍수예경보를 이용하여 예보된 유입량을 활용하면 최적의 방류시점과 방류량을 산정하여 홍수기 다목적댐을 효율적으로 운영할 수 있으며 주요 지점의 홍수량도 저감할 수 있을 것으로 판단된다.

소비 양극화에 따라 중산층의 붕괴가 이어지고 있다. 실제 미국의 탄산음료 판매는 2015년 3%의 매출 하락폭을 보였고, 국내 소비 또한 GDP 대비 민간소비 비중이 5.1%포인트 감소하는 등 불황의 그림자가 짙게 드리워져 있다. 그러나 생활용품관련 소비의 감소에도 불구하고 명품 소비는 지속적으로 증가하는 등 소비의 양극화가 심화되고 있는 실정이다. 한편 오프라인 매출이 감소하고 있는 반면 온라인 매출은 지속적으로 증각하고 있는 상황에서 온라인 의사결정에 영향을 미치는 요인이 무엇인지를 알아보는 것은 의미있는 일이라 할 수 있다. 이에 본 연구에서는 "결혼(mating goal)"을 프라이밍시키는 것이 남.녀의 의사결정에 어떤 영향을 미치는지를 알아보았다. 나아가 불확실한 의사결정상황에서 남녀의 의사결정에 영향을 미치는 요인에 대해 추가로 살펴보았다. 연구결과 "결혼(mating goal)"을 프라이밍시키면 불공정한 제안을 거부하는 데 차이가 없지만, 여성의 경우에는 mating goal을 상기시키면 불공정한 제안을 더 많이 거부하는 것으로 나타났다. 이는 mating goal이 여성들로 하여금 좀 더 자신의 의견을 강하게 표현하도록 하는데 영향을 미칠 수 있다는 점을 보여주고 있다.

Questions of why, what, and how represent the new perspective on goal construct. This paper proposed a novel approach toward the goal construct as a dynamic decision-making process. A number of researchers have agreed that goals initiate and sustain human motivation. In spite of the consistency in emphasis on goals, there are apparent inconsistencies in definitions of goal construct across theories and research. These inconsistences hinder interdisciplinary communication about goal construct, which in turn leads to jingle-jangle fallacy. Therefore, on the basis of systematic literature review, I defined the goal construct as a multifaceted and hierarchical decision-making process to structure desired end-states. The first process is generating goals, which can be also called "why" process. During this phase, individuals generate cognitive schema about general direction of desired end-states based on the conscious and nonconscious interpretation of subjective experience. The second process is goal setting, which can be called "what" process. Here, individuals clarify contents of multiple goals and structure hierarchy and priority of them. The last process is implementing goals, "how" process. This process contains decision making about whether he/she decides to implement the goal or not and how to execute goal-directed behaviors. In the last section of this paper, I tried to suggest several practical applications of this new perspective for adolescents, who struggle with why-what-how to have goals in learning context.

Decision environments involve a high degree of uncertainty as well as multiple, conflicting goals. Although traditional goal programming offers a means of considering multiple, conflicting goals and arrives at a satisficing solution in a deterministic manner, its major drawback is that decision makers often specify aspiration level of each goal as a single number. To overcome the problem of setting aspiration levels, chance constrained programming can be incorporated into goal programming formulation so that sampling information can be utilized to describe uncertainty distribution. Another drawback of goal programming is that it does not provide a systematic approach to set priorities and trade-offs among conflicting goals. To overcome this weekness, the analytic hierarchy process(AHP) is used in the model. Also, most goal programming models in the literature are of a linear form, although some nonlinear models have been presented. Consideration of risk in technological coefficients and right hand sides, however, leads to nonlinear goal programming models, which require a linear approximation to be solved. In this paper, chance constrained reformulation with linear approximation is presented for a 0-1 goal programming problem whose technological coefficients and right hand sides are stochastic. The model is presented with a numerical example for the purpose of demonstration.

Purpose - This study aims to explore the factors that can trigger the escalation of an initially pursued long-term utilitarian goal that is set aside to pursue a competing hedonic goal. Research Design, Data, and Methodology - The experimental study covered three groups : Group 1 (ego-depletion, self-referencing), Group 2 (ego-depletion, neutral), and Group 3 (no ego-depletion, neutral). The participants of the study comprised 150 undergraduates who were divided into three groups of 50 students for each. One-way ANOVA and regression analyses were used to verify the hypotheses. Results - Ego-depleted consumers are less likely to resist immediate temptation than those who are not in an ego-depletion state. Self-referencing has a positive impact on long-term goal reversion when consumers in an ego-depletion state experience immediate temptations. Counteractive construal plays a mediating role between self-referencing and long-term goal reversion. Conclusions - We found that consumers tend to yield to momentary temptations when they are in an ego-depletion state. Self-referencing and counteractive construal can eliminate the ego-depletion effect and then facilitates escalation of the set-aside long-term goal.

Purpose - Loyalty programs enable retailers to maintain longer and better customer relationships. In successful services, customers actively use and value these programs. As the proximity to the goal (goal gradient) might signal active participation, this study empirically examines customer's goal gradient behavior in a multi-vendor loyalty program. We also consider the effect of customer's accrual diversity on goal gradients, which is a differentiating feature in a multi-vendor loyalty program, and is further examined. Research Design, Data, and Methodology - The data consists of6,646 OK Cashbag members' individual transaction records from 2006 to 2009. The goal gradient hypothesis was tested as an increase in both the speed and the amount of accumulated award points. Result - The findings suggest that the goal gradient is also observed in a multi-vendor loyalty program, occurring more strongly among members with high accrual diversity. Conclusions - The results indicate that customers with high accrual diversity attend strongly to goal gradients in multi-vendor loyalty programs; hence, it is important for such program managers to better inform members about affiliated partners.

Under the needs to study the predictors of the frontline employees' service-oriented organizational citizenship behaviors(OCBs) in the hotel industry, this study aimed to the influence of goal orientations on the OCBs. The two factors of performance goal and learning goal orientations were hypothesized to influence each dimension of OCBs(loyalty, service delivery, and participation). The data from 266 five star deluxe hotel employees were analyzed with descriptive statistics, multi-variate analysis of variance, and structural equation modeling conducted using SPSS 19.0 and AMOS 20.0. The results showed learning goal orientation positively influenced all dimensions of the OCBs while performance goal orientation positively influenced all dimensions except loyalty. These results suggest that hotel practitioners need to seek the applicants who are willingly oriented to specific goals at recruiting process. Furthermore, hotel organizations need to utilize the employees' goal approach to motivate their performances.

Based on King's goal attainment theory, this research deals with applying nursing intervention of mutual goal settings to gastrectomy patients. It tests the effects of nursing intervention, according to the patients' health locus of control, suggested as external boundary criteria for the theory by employing a quasi-experimental design which consists of a pretest-posttest non-equivalent control and experimental groups. The subjects of this research were 62 gastrectomy patients hospitalized at Y medical center and the experimental and control groups consisted of 31 subjects. The experimental group received nursing intervention at the mutual goal setting of 5 times from the day before the surgery to the 5th day after the surgery, while the control group received only routine nursing care. Recovery indicators of both groups were measured and compared. Measurement variables included patients' characteristics, health locus of control, forced vital capacity, forced expiratory volume in one second, peak expiratory flow, bowel movement recovery, mobility recovery, level of pain, patients' stress and patients' satisfaction. Data were analyzed using SPSS statistical package and the hypotheses were tested by ANOVA and ANCOVA. Results of the analyses are summarized as follows : 1) Internal health locus of control had higher effects of the nursing intervention of mutual goal setting than external health locus of control on pulmonary ventilatory functions of forced vital capacity, forced expiratory volume in one second, and peak expiratory flow. 2) There was no statistically significant difference in the effects of nursing intervention of mutual goal setting on the bowel movement recovery between the internal and external health locus of control. 3) There was no statistically significant difference in the effects of nursing intervention of mutual goal setting on the mobility recovery between the internal and external health locus of control. 4) There was no statistically significant difference in the effects of nursing intervention of mutual goal setting on the level of pain between the internal and external health locus of control. 5) There was no statistically significant difference in the effects of nursing intervention of mutual goal setting on the level of stress between the internal and external health locus of control. 6) There was a statistically significant difference in the effects of nursing intervention of mutual goal setting on the level of satisfaction with provision of nursing information between the internal and external health locus of control, and there was no statistically significant difference in the effects of nursing intervention of mutual goal setting on the level of satisfaction with outcome of nursing between the internal and external locus of control. On the basis of the research results, the following are recommended : 1) Repeated research on responses to health locus of control is necessary. 2) Not only the effectiveness of nursing intervention in acute recovery periods, but also the long term effects are to be investigated. 3) The development of instruments is needed to accurately measure mutual goal setting regarding postoperative deep breath, coughing, early ambulation, etc. so that the relationship among the postoperative recovery indicators may be explored. 4) It is required that an instrument be developed to measure perception which facilitates goal attainment in the interactive setting between patients and nurses.
