In the cellular mobile communications as decreasing the cell radius to increse the reuse factor of frequencies, the handoff requests are increasing so that the efficient handoff decision making becomes a crucial problem. In this simulation study, we evaluate a set of handoff algorithms based on fuzzy-multicriteria decision making. These algorithms uses the parameters including the received signal strength intensity, the bit error rate and the distance between a mobile station and a base station. We compare the fuzzy algorithms in terms of call block ratio and handoff request ratio and call force ratio, and show the applicability of those algorithms in the cellular mobile communication systems.

An important decision-making element for the success of housing redevelopment projects is a prediction of the profitability of redevelopment. Risk factors influencing profitability were deduced through a review of the literature about profitability and a risk analysis developed by a survey of maintenance projects. In addition, a profitability prediction depending on the analysis of risk factors is necessary to judge the business feasibility of a project in the planning stages. A profitability prediction model of management and disposal method, which is calculated by proportional rate and which helps estimate contributions to profitability, is proposed to prevent difficulties in business development. The proposed model has the potential to prevent interruptions, reduce the length of projects, generate cost savings, and enable rational decision-making during the project period by allowing a judgment of profitability at the planning stage.

This study examined the influence of consumer self-confidence and self-confidence in fashion coordination on the attitude toward secondhand fashion goods and the purchase intention of secondhand fashion goods. Questionnaire data from 346 university students were analyzed and the results were summarized as follows. First, there were five factor solutions in consumer self-confidence: information acquisition, personal outcomes decision making, social outcomes decision making, consideration-set information, persuasion knowledge. Second, information acquisition, social outcomes decision making, and consideration-set information had significant effects on self-confidence in fashion coordination, while personal outcomes decision making and persuasion knowledge had no effect on self-confidence in fashion coordination. Third, self-confidence in fashion coordination had a significant effect on attitude toward secondhand fashion goods however, it had no effect on purchase intention of secondhand fashion goods. Fourth, attitude toward secondhand fashion goods had a significant effect on the purchase intention of secondhand fashion goods. The results show diverse implications for marketers and managers of secondhand fashion goods.

The server privilege account must be operated through law and regulation. However, due to regulation non-compliance and inadequate operation on financial company server privilege, an incident that every server data being deleted by hacker occur which is later being named as 'NH Bank Cyber Attack'. In this paper, the current operation status on financial company privilege accounts is being analysed to elicit problems and improvement. From the analysis, important evaluation factors will be also selected and applied generating the decision making model for financial company server privilege account operation. The evaluation factor deducted from privilege account status analysis will be used to present and verify the decision making model and formula through AHP(Analytic Hierarchy process).

The purpose of the study was to explore effects of fashion related work experience program and its satisfaction in middle schools. The study analyzed differences in self-efficacy of career decision making and fashion related career maturity before and after the program. The questionnaire developed by the researchers was collected from 114 participants enrolled in middle schools in Seoul or Kyunggido. The data were analyzed by common factor analysis, and independent sample t-test, using SPSS 18.0/Windows. The results demonstrated significant higher scores in self efficacy of career decision making, and fashion related career maturity after the program than before. Also, they showed high program satisfaction scores. The results of the study could be basic information for work experience program developers for high and middle school students.

The purpose of the study was to investigate the influencing factors of autonomy preference on decision-making among chronic disease patients. Data were collected from 522 chronic disease patient and it was analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and multiple linear regression, using SPSS 26.0 ver. program. Significant factor influencing decision-making preference was health concern (β=-.17, p<.001), and factors influencing information-seeking preference were gender (β=-.20, p<.001) and number of questions during the treatment (β=.09, p=.030). Healthcare providers should take into account the characteristics of patients and establishment of a strategy to improve the quality of communication.

In a world where opportunities and chances are common, the phenomenon referred to as "generation maybe" describes people in their 20s and early 30s who are usually being indecisive. With the increase in breadth of information and choices, the number of people who are hesitant in deciding whether to purchase increases at a fast pace, as does the number of products and services targeting this group. In order to enhance our understanding of the phenomenon of consumer hesitation, this study explores contextual factors and consumer characteristics that affect consumer hesitation in the purchase decision-making process. Specifically, this study examines whether seven contextual factors, self-determination tendencies, and five decision-making styles influence consumer hesitation in the product decision making process. An online survey was administered to test our research questions. A total of 309 Korean consumers (female=48.9%) aged from 20 to 35 were surveyed. A regression analysis revealed that four contextual factors (product involvement, need for information on alternatives, relative price, and uncertain need), two sub-dimensions of self-determination (perceived competence and relatedness), and two decision-making styles (price seeking and advice seeking) have noticeable influences on consumer hesitation. We also found that the degree of consumer hesitation positively influences consumer post-purchase satisfaction. The study concludes with discussions and practical implications.

The purpose of this study was to examine the relationship between career decision-making self-efficacy, character strength, and gratitude as a factor influencing the happy life of adults. Subjects were 89 adults in university and graduate school. SPSS 23.0 and PROCESS Macro were used for data analysis. Significant correlations were found between career decision-making self-efficacy, character strength, gratitude, and happy life. The direct effect of career decision-making self-efficacy, an independent variable, on happy life, a dependent variable, was not significant. Character strength and gratitude, which are mediators, were significant. Therefore, the indirect effect and the total effects showed significant results. Career decision-making self-efficacy does not directly predict a happy life, but if it mediates character strengths and gratitude, it means that a happy life can be predicted.

This study aims to investigate the effect of college students' major satisfaction on career decision-making self-efficacy and job confidence. The research method was used for analysis by surveying 335 two-year college students majoring in beauty in Seoul and Gyeonggi-do. The collected data were analyzed for frequency analysis, factor analysis, reliability analysis, and correlation between career decision-making self-efficacy and job confidence using SPSS 26.0, and multiple regression analysis was conducted to confirm the effect between each variable. As a result of the study, first, a statistically significant positive (+) correlation between college students' major satisfaction was confirmed between career decision-making self-efficacy and job confidence. Second, as the effect of major satisfaction on self-efficacy, statistically significant effects were confirmed in self-evaluation, problem-solving, and goal selection. Fifth, it was confirmed that major satisfaction had a statistically significant effect on job confidence. Fourth, it was confirmed that career decision-making self-efficacy had a statistically significant effect on job confidence.
