The concept known as Vehicle-to-Grid (V2G) is to provide power to help balance loads by charging at night when demand is low and sending power to the grid when demand is high. Therefore, it is important to model the cost-benefit characteristics of Electric vehicle(EV)'s operation considering the negawatt market in real time. This paper proposes a methodology to formulate the various costs and economic benefits for sending the EV's power back to the grid, including a concept of inconvenience costs caused by operating the EV as a battery. This paper also introduces the general decision-making process based on the cost-benefit analysis in order to simulate the reasonable participation of V2G service. In the case study, it is confirmed by two-case simulations that the proposed approach is useful to help EV owners' decision-making. In the future, it is expected that the proposed methodology can be used as a decision-making guideline to help prepare the EV' power transmission.

Purpose: The purpose of this study was to investigate the effects of 'career decision making', 'school career education activities and participation', and 'school career education satisfaction' after 568 high school students. Methods: The subjects were surveyed after the counseling training. Results: 49.3% of the respondents answered that they had "decided but considered" in the "career decision information items" of the questionnaire about the subjects after the school career counseling education. 28.0% of the parents' advice was the most helpful when choosing their career, and 52.2% of the career decision making at school. There were 13 items in 'participation in school career education activity', and the average value was 3.49. The highest score was 3.66 points for "college or major experience" and the lowest score of 3.27 points for career-linked career education. In 'satisfaction with School Career Education', 94.7% of creative experiential activities and 94% of career and vocational courses were enthusiasts, and entrepreneurship and entrepreneurship experience (10.6%) were low. The career decision - making self - efficacy was also high in the group with high satisfaction of career education. Conclusions: School career decisions for high school students were effective when they were devoted to parental advice, university experience, creative vocational and career, and vocational education. The career decision - making self - efficacy was high in the group with high satisfaction of career education. Therefore, career counseling education considered adequate if it is devoted to education professionals.

The purposes of this study were (1) to describe patients' behaviors to protect themselves from medical errors and their involvement in decision making on the diagnostic and treatment procedures (2) to examine whether patients' characteristics, such as age, sex, education, experience of hospitalization and/or surgery influence their self protect behaviors and involvement in decision making on the diagnostic and treatment procedures. A survey was conducted with 99 patients visited one university hospital in Seoul, Korea. A 20-item questionnaire, a 4-point Likert scale, was used to measure the degree of patients' active involvement in decision making; patients' self protect behaviors regarding medication, hospitalization, and surgery; and communication (Cronbach's alpha=0.801). SPSS 12.0 was used for the descriptive and correlation analysis. Only 6.1% of the participants were involved in the decision making process for the diagnostic tests and treatment. More patients did self-protect behaviors associated with the medication than other areas but widely varied from 18.2 to 94.3 % among various items. More people with age of 60 or older compared to people in younger age groups reported more protect behaviors particularly associated with medication. Patient education is needed to improve their active role in preventing medical errors and to promote patients' safety.

This study evaluated methods of improving sustained learning participation by examining the structural relationship of school support consisting of professor support, friend-senior support and educational environment support, career decisionmaking self-efficacy, school satisfaction, and learning persistence depending on the characteristics of college students majoring in culinary art and food service. The study findings were as follows. First, the general characteristics of college students majoring in culinary art and food service were perceived significantly more by female students than by male students. Second, school support directly influenced the career decision-making self-efficacy and school satisfaction, but did not directly influence the learning persistence. Instead, school support influenced school satisfaction and learning persistence indirectly by the medium of career decision-making self-efficacy. Third, career decision-making self-efficacy directly influenced school satisfaction and learning persistence and indirectly influenced learning persistence by the medium of school satisfaction. Lastly, school satisfaction directly influenced the learning persistence, implying that school satisfaction is an important factor for the learning persistence of college students majoring in culinary art and food service. These results show that, because school members and environmental support cannot exclusively make learning persistence, diverse systems and programs must be developed and applied to improve the career decision-making self-efficacy and school satisfaction of college students majoring in culinary art and food service.

This cross-sectional descriptive and qualitative study was aimed to study the people participation and their approaches toward the human carcinogenic liver fluke, Opisthorchis viverrini, prevention and control in Ban Chaun sub-district administrative organization (BCSAO) and Bamnet Narong sub-district municipality (BNSM), Bamnet Narong district, Chaiyaphum Province, Thailand between June 2013 and February 2014. Participants were purposive selected, included chiefs of sub-district administrative organizations, sub-district municipalities, sub-district health promotion hospitals (SHPHs), heads of village, and a further sample was selected with a multi-stage random sampling for public health volunteers, and villagers. The pre-designed questionnaire contained items for individualized status and the participatory steps of sharing ideas, decision-making, and planning, procession, evaluation, and mutual benefit, for the project O. viverrini prevention and control (POPC). In-depth interviews were used for collection of need approaches to POPC. With 375 participants who completed the questionnaire, it was found that people had a high level regarding to participate in the POPC, particularly in the process stage ($\bar{X}=3.78$, S.D. = 0.56), but the lowest level was found in sharing ideas, decision making, and planning step ($\bar{X}=3.65$, S.D. = 0.63). By comparison, participant status and organization did not significantly differ with people participation. In each step, Ban Chaun sub-district had a high level of participation in the step of sharing ideas, decision making, and planning toward POPC, more than Bamnet Narong sub-district municipality (t=2.20, p=0.028). Approaches for POPC in Ban Chaun sub-district and Bamnet Narong sub-district municipality included requirements for budget support, annual campaigns for liver fluke prevention and control, campaign promotion, risk group observation, home visiting, community rules regarding reducing raw fish consumption in their communities, and a professional public health officer for working in their communities, BCSAO, BNSM, and SHPH, for O. viverrini prevention and control. This study indicates that people realize that eradication of the liver fluke needs a continuous people participation for O. viverrini prevention and control in their communities.

The purpose of this study is to develop value instruction program which can deal with geographic value problem(GVP) in geographic education. This program is organized into seven stages: identification of GVP(reading of content of GVP, and categorization and description of action which involved in content), analysis of GVP(comparison and analysis of GVP, and ordering of value positions), decision making, justification of decision making and actualization. The processes of decision making and their related activities are emphasized in this program. In experimental classroom, it took effects to providing subjective experiences with students, developing decision making ability, and giving responsibility of decision making. Therefore this study suggests that this program helps students to improve their social participation ability as the democratic citizenship.
