This study investigates the effect of perceived risk on attitude toward mobile Social Network Services (SNSs). First, we understand that perceived risk of SNSs is a multidimensional concept, and we study the relationship between attitude and perceived risk such as social risk, performance risk, and privacy risk in SNS environments. Subsequently, the relationships between these multidimensional concepts of perceived risk and attitude are investigated. The result indicates that social, performance, and privacy risk have negative effects on attitude. In addition, the moderated effect of individual characteristic variables such as hedonic value and self-construal are confirmed as mitigating factors that alleviate the negative impact of perceived risk. The Findings show that customers who perceive SNSs to be risky are more likely to have a negative attitude toward SNSs. However, the negative impact of perceived risk on their attitude toward SNSs is alleviated in customers with high hedonic value. Similarly, the negative impact of perceived risk on their attitude toward SNS is weaker with customers in interdependent self-construal. This paper presents effective segmentation variables, such as consumer's motivation (hedonic value) and psychological variable (self-construal), which mitigate the risk perception of customers. Therefore, it provides practical guidelines for the marketing managers in terms of who to target and what kind of strategies to implement in terms of these segmentation variables to approach consumers more efficiently.

The aim of this study was to explore the mediating effects of adult attachment and marital satisfaction on the relationship between childhood maternal attachment and parenting behavior. A total of 372 mothers of preschoolers completed questionnaires on childhood maternal attachment, adult attachment, marital satisfaction, and parenting behavior. Adult attachment was analyzed by distinguishing between attachment anxiety and attachment avoidance. Parenting behavior was categorized into positive and negative behaviors. For the main analyses, Preacher and Hayes's PROCESS macro program was used to examine serial mediating effects. The results revealed that attachment anxiety mediated the effects of mothers' childhood attachment experiences on both positive and negative parenting behavior. However, attachment avoidance only mediated the effects on positive parenting behavior. Marital satisfaction mediated the effects of mothers' childhood attachment experiences on both positive and negative parenting behavior. Notably, the sequential mediating effects of attachment anxiety and marital satisfaction were not significant for either positive or negative parenting behavior. By contrast, the sequential mediating effects of attachment avoidance and marital satisfaction were significant for both positive and negative parenting behavior. These findings elucidate the predictive factors for parenting behavior within a process model framework, providing valuable insights for parental education and counseling aimed at enhancing mothers' parenting practices.

This study examined the relative effects of positive and negative reinforcement on customer service behaviors. In addition, we examined whether the intervention would lead to response generalization on non-target behaviors. Five employees at three different convenient stores participated and ABC/ACB within-subject design was adopted. For the three participants, followed by the baseline(A), the positive reinforcement was first introduced(B) and the negative reinforcement(C) was introduced for the next phase. For the remaining two participants, the negative reinforcement(C) was first introduced after baseline(A) and the positive reinforcement (B) was introduced. Results showed a greater improvement in target behaviors under the positive reinforcement condition than that of the negative reinforcement condition. In addition, both reinforcement condition cause response generalization on non-targeted service behaviors, however, the comparable effects was found between two reinforcement conditions. Post-interview indicated that participants experienced positive emotions under positive reinforcement condition and negative emotions under negative reinforcement condition. These results suggest that the he techniques using positive reinforcement can be more effective and efficient to improve the work performance.

Recently, a variety of data mining techniques has been applied in various fields like healthcare, insurance, and internet shopping mall. Association rule mining is a popular and well researched method for discovering interesting relations among large set of data items. Association rule mining is the method to quantify the relationship between each set of items in very huge database based on the association thresholds. There are three primary quality measures for association rules; support and confidence and lift. In this paper we consider some similarity measures with negative co-occurrence frequencies which is widely used in cluster analysis or multi-dimensional analysis as association thresholds. The comparative studies with support, confidence and some similarity measures are shown by numerical example.

Objective: The aim of this study was to investigate the association between conceptual metaphors of affect and physical dimensions. Background: The evidence that affect is unconsciously linked to physical dimensions(e.g., position and color) has been obtained in western cultures. However, in eastern cultures, especially, in Korea, it has been seldom tested. It is indispensable to examine whether or not cultural differences exist for better understanding of the conceptual metaphors. Method: 50 positive and 50 negative words were adopted from previous studies in order to determine the relationship between physical domains and abstract affect. Three hypotheses were tested in this study: (1) Good is up. (2) Good is bright. (3) Good is right(for right-handers). The automatic association between valence(positive vs. negative) and vertical position (up vs. down) was investigated in experiment 1, in which 100 words were randomly presented on either the top or the bottom of a LCD screen and the evaluation time of the presented word was recorded. The unconscious association between valence and color(white and black) was examined in experiment 2, where each word was randomly presented in either white or black. Lastly, we tested whether right-handers tend to associate rightward space with positive ideas and leftward space with negative ideas. Results: Reaction time was faster when words were presented in metaphor congruent domains(e.g., 'positive words on the top, in bright color, and on right space vs. negative words on the bottom, in dark color, and on left region) than when they were shown in metaphor incongruent domains. Conclusion: The results might give the groundwork for various directions in further understanding perception, emotion, and behavior. Application: This study may provide useful points to GUI designers and service developers if further studies enhanced in validity and reliability are followed.

The aim of this study was to construct and test a structural equation model for the risk factors of metabolic syndrome in Korean adults. The structural equation model hypothesizes that eating alone and feeling depressed is a risk factor for metabolic syndrome. The data of this study were obtained from the Sixth Korea National Health and Nutrition Examination Survey which was cross-sectional data from the representative national survey. A total of 4,013 subjects replied to the survey item of lifestyle and completed the physical examinations among adults aged 19 years or older in South Korea was in 2015. The structural model in this study was composed of four latent variables: eating alone, depression, negative health behavior, and metabolic syndrome. Two variables, the rate of eating alone and depression, were exogenous variables. Negative health behavior was both a mediating variable and endogenous variable, and metabolic syndrome was the final endogenous variable. The data were analyzed using the Maximum Likelihood method and bootstrapping. The structural model was appropriate for the data based on the model fit indices. The results of this study can be summarized as follows: Eating alone is a direct risk factor of metabolic syndrome in Korean women. Depression can mediate metabolic syndrome through negative health behaviors. Negative health behavior had a direct impact on metabolic syndrome in both men and women. This study may be a guideline for interventions and strategies to reduce the incidence of metabolic syndrome in Korean adults.

Purpose - There are many antecedences and consequences of the positive emotions of customers. The purpose of this research is to examine how Chinese service companies improve not only the positive emotions of customers but also the quality of life through effective verbal and nonverbal communication. Furthermore, we tried to analyze the moderating role of negative expectancy disconfirmation perceived by customers in those causal relationships among the variables. Research design, data, and methodology - The eight hypotheses were proposed and we tested them empirically in this research. Four hypotheses were about the relationship among communication, positive emotion, trust and quality of life. The other four hypotheses were about the moderating effect of negative expectancy disconfirmation in the causal relationships among four variables such as communication, positive emotion, trust and quality of life. A total of 356 samples who had visited the service companies in China were surveyed and 8 hypotheses were tested by empirical analysis using SPSS and AMOS. Results - The results of this research are as follows. First, positive verbal communication and nonverbal communication of employees in the service company have a positive effects on the positive emotions of customers. Second, positive emotion has a positive effect on the overall quality of life on the customer side as well as the trust on the corporate side. Third, negative expectancy disconfirmation perceived by customers has negative moderating effect in the causal relationship between employees' positive verbal communication and customers' positive emotion, and it also has a negative moderating role in the causal relationship between customers' positive emotion and overall quality of life. Conclusions - Based on these results, there can be such implications as follows. First, managers and employees of service companies can induce positive emotion of customers through effective communication. Second, service companies should try to improve not only the corporate-side performance like trust but also the customer-side performance like quality of life. Third, it will be significant for them to lower the level of negative expectancy disconfirmation for the purpose of improving not only the positive emotions of customers but also the quality of customers' life.

The purpose of this research is to examine the causal relationships between an infant's negative emotionality, the mother's reactive parenting, and the infant's problem-solving ability. This research used a Panel Study with Korean Children's 1st-3rd year data, and the subjects were 1789 infants and their mothers. To process the results, descriptive statistics, reliability verification, Pearson's product moment correlation analysis, and path analysis were conducted. The results of this research are as follows: First, the infant's negative emotionality had significant negative effects on the mother's reactive parenting. Second, the mother's reactive parenting had significant positive effects on the infant's problem-solving ability. Third, the infant's negative emotionality had indirect effects on the problem-solving ability. Through the results of this research, it could be interpreted that the path, the infant's negative emotionality, which is a personal factor, and the mother's reactive parenting, which is an environmental factor, had effects on the infant's problem solving ability. Furthermore, basic data to explore the ways of promoting the infant's problem solving ability could be introduced.

The purpose of this study is to investigate the effect of toddler's emotionality and mother's reaction to their child's negative emotions of social-emotional behaviors of toddlers. The subjects were 141 mothers and toddlers ranging in age from 18 to 36 months. Instruments used in this study were: 1) Early Childhood Behavior Questionnaire(ECBQ)(Rothbart, 1994), 2) Coping with Toddlers' Negative Emotions Scale(CTNES)(Eisenberg et al., 1996), and 3)Brief Infant Toddler Social and Emotional Assesment(BITSEA)(Carter et al., 2006). Data were analyzed using Pearson's correlation and hierarchical multiple regression analysis. The results of this study show that toddler's emotionality and the mother's negative reaction to their child's negative emotions were related to the social-emotional behaviors of toddler. Also, mother's reaction to their child's negative emotions have mediation effects between toddler's emotionality and social-emotional behaviors. Specifically, toddler's emotionality has a partial mediating effect on social-emotional behaviors through mother's supportive reaction to their child's negative emotions. Additionally it was also determined that the toddler's emotionality has a complete mediating effect on the relationship between mother's unsupportive reaction to their child's negative emotions and the social-emotional behaviors of toddler. Theses results support the notion that mother's character as well as child's personality at birth are critical predictors which could impact social-emotional behaviors of toddler.

Purpose: Precise localization of tumors and creation of sufficient proximal resection margins are complicated processes during total laparoscopic distal gastrectomy (TLDG) for clinical T1/T2 gastric cancers. Various solutions to this problem have also yielded many disadvantages. In this study, we reviewed a preoperative endoscopic clipping method based on the results of negative biopsy and selective intraoperative radiography. Materials and Methods: A retrospective review of 345 consecutive patients who underwent TLDG and preoperative endoscopic clipping for tumor localization was conducted. During preoperative endoscopy, the endoscopists performed negative biopsies just 1-2 cm selectively above the tumor's upper limit. After confirming the biopsy results, endoscopic metal clips were applied just proximal to the negative biopsy site the day before surgery. Selective intraoperative tumor localization using portable abdominal radiography was performed only when we could not ensure a precise resection line. Results: Negative biopsy was performed in 244 patients. Larger tumor size (P=0.008) and more distally located tumors (P=0.052) were observed more frequently in the negative biopsy group than in the non-negative biopsy group. The non-negative biopsy group had significantly higher frequencies of differentiated tumor types than the negative biopsy group (P=0.003). Of the 244 patients who underwent negative biopsies, 6 had cancer cells in their biopsy specimens. We performed intraoperative radiography in 12 patients whose tumors had difficult-to-determine proximal margins. No tumors were found in the proximal resection margins of any patients. Conclusions: Our tumor localization method is a promising and accurate method for securing a sufficient resection margin during TLDG.
