본 연구는 한국인들이 어떠한 생활경험을 했을 때 자신이 행복하다고 판단하는지와 그러한 경험을 통해서 어떠한 정서가 유발되는지를 검토함으로써 실제 경험에 토대한 행복의 구성 내용을 체계화하려는 목적으로 시도되었다. 이를 위해서 대학생과 중년의 성인 남녀 총 489명을 대상으로 살아오면서 행복 혹은 불행했던 경험과 그로 인해 유발된 정서적 반응을 강도와 빈도 차원에서 분석하였다. 그 결과는 다음과 같다. 첫째, 강한 행복이나 불행을 유발하는 경험은 성취와 실패 경험이었고, 빈번한 행복 유발 경험은 가족이나 친구와의 사회적 관계경험이었다. 둘째, 강한 긍정적 정서는 성취감이나 자부심이었지만, 빈번하게 경험되는 긍정적 정서는 편안함이나 유대감과 같은 긍정적인 관계정서들이었다. 셋째, 강한 부정적 정서는 절망과 슬픔이었지만, 빈번하게 경험되는 부정적 정서는 섭섭함, 미안함, 수치심과 같은 부정적인 관계정서와 불안이었다. 이러한 결과는 개인적 목표의 달성과 더불어 가족이나 친구를 중심으로 한 사회적 관계 경험이 한국인의 행복과 불행을 구성하는 중요한 요소임을 시사한다.

This study investigates the effects of a two-sided message on product attitude and purchase intention by using a message structure variable, such as attribute importance in the context of online consumer reviews (OCRs). Study 1 explains the previous inconsistent results of a two-side message by comparing a one-side message and a two-side message by using the attribute importance in negative reviews. Study 2 determines the reasons for the inconsistent results of a refutational two-sided message research by using the attribute importance in negative reviews and website trust. Two experiments are designed to test our hypotheses. The first experiment is a $2{\times}2$ factorial design with 84 participants. The second experiment uses a $2{\times}2{\times}2$ factorial design with 196 participants. In study 1, two-sided OCRs are more credible than one-sided OCRs, and two-sided OCRs that use low important attributes are more effective in making favorable product attitude/purchase intention. In study 2, refutational two-sided OCRs that use high attribute importance render positive effects on product attitudes in trustworthy websites. However, the refutation could negatively affect product attitude/purchase intention in low trustworthy websites.

The objective of this study is, first of all, to investigate the positive and the negative interaction between the work and family lives of married company employees. Secondly, it is to investigate the variables affecting this matter. The conclusion drawn by the result acquired through process is as follows. First, married company employees feel positive more than negative because of the influence that their families have on their work. Secondly, male employees feel more of the positive influence that family has on their work more than the female employees do. Thirdly, with respect to the type of business, self-employed individuals and specialized managers seemed to have negative influences on the interaction between work and family. Fourthly, it was found that the managerial ability of the individual is a variable that affects both directions. Fifthly, it was observed that variables related to family affect the interaction between work and family in the positive direction. Finally, the negative influence between work and family was decreased by family coherence.

This study analyzed the internal-external controls, psychological well-being and depression of mothers as factors that affect mothers's parenting style of young children. The participants were 228 mothers of preschoolers. Data were analyzed by descriptive statistics, Pearson's productive correlation, and stepwise multiple regression analysis. Results showed that positive mothers parenting style had positive relationships with internal control and psychological well-being. On the other hand, positive mother's parenting style had negative relationships with external control and depression. In addition, negative mother's parenting style had positive relationships with external control and depression. On the other hand, negative mother's parenting style had no relationship with psychological well-being and internal control. Psycholobrical well-being had the strongest effect on positive mother's parenting style and external control had the strongest effect on negative mother's parenting.

The predominant type of buckling that I-steel concrete composite beams experience in the negative moment area is distortional buckling. The key factors that affect distortional buckling are the torsional and lateral restraints by the bottom flange. This study thoroughly investigates the equivalent lateral and torsional restraint stiffnesses of the bottom flange of an I-steel concrete composite beam under negative moments. The results show a coupling effect between the applied forces and the lateral and torsional restraint stiffnesses of the bottom flange. A formula is proposed to calculate the critical buckling stress of the I-steel concrete composite beams under negative moments by considering the lateral and torsional restraint stiffnesses of the bottom flange. The proposed method is shown to better predict the critical bending moment of the I-steel composite beams. This article introduces an improved method to calculate the elastic foundation beams, which takes into account the lateral and torsional restraint stiffnesses of the bottom flange and considers the coupling effect between them. The results show a close match in results from the calculation method proposed in this paper and the ANSYS finite element method, which validates the proposed calculation method. The proposed calculation method provides a theoretical basis for further research on distortional buckling and the ultimate resistance of I-steel concrete composite beams under a variable axial force.

Background: Many patients with complex regional pain syndrome (CRPS) have been known to be at risk of suicide, due to severe pain and its comorbid conditions. The risk of suicide may be associated with affective instability, which is an indicator of emotional dysregulation. Particularly, unstable shifts in negative emotions are difficult to cope with, which may result in individuals feeling uncontrollable, hopeless, and entrapped. This study aimed to examine the role of affective instability in the relationship between pain intensity and suicide risk (suicidal ideation and impulsivity) in patients with CRPS, by employing a daily diary. Methods: Twenty-three patients registered at the CRPS Association in Korea were asked to complete a day-to-day routine for 15 days, followed by a diary composed of pain intensity, suicidal ideation, impulsivity, and positive and negative affects. Results: Results showed that the interactions between negative affective instability and daily pain intensity were statistically significant on daily suicidal ideation (coefficient = 0.41, t (21) = 2.56, P < 0.050) and daily impulsiveness (coefficient = 1.20, t (19) = 3.35, P < 0.010). However, those between positive affective instability and daily pain intensity were not. Conclusions: This study is the first attempt to investigate the role of affective instability on the relationship between daily pain intensity and daily suicide risk in patients with CRPS. Our findings suggest that health professionals pay considerable attention to the instability of negative affects when assessing and managing patients with CRPS at risk of suicide.

As an empirical study on the psychological side effects of using Social Networking Services (SNS), this study aims to identify the reality of negative emotion of using SNS and to predict its consequences. To this end, a measurement tool was developed through literature review, in-depth interview with users and expert review to induce negative emotional factors that can arise while using SNS. An exploratory factor analysis was performed for a total of 24 measurement items, which then were divided into the following 6 factors: 'concern over privacy,' 'burden from undesired connection,' 'relative deprivation,' 'a sense of alienation,' 'concern over reputation' and 'negative feeling about simple relationship.' Also, the relationship between the 6 negative emotional factors and psychological dissonance was analyzed. The results indicate that all the factors, except relative deprivation and a sense of alienation, affect psychological dissonance. It was also found that psychological dissonance, which implies a conflicting condition from using SNS, significantly affects the behavior that possibly reduces and limits the use of SNS. In other words, the users who have experienced psychological dissonance respond passively by avoiding the use of SNS to resolve the dissonance. The results of this study provide the base for explaining the psychological side effects of using SNS, which have been understood at a phenomenal level, such as 'Facebook depression' or 'SNS stress.' In addition, this study is of significance as it helps understand the psychological mechanism by identifying the relationship between negative emotion and use behavior with the theory of cognitive dissonance.

본 논문에서는 유전율($\varepsilon'$)과 투자율($\mu'$)이 양수인 double-positive (DPS) 물질에서 정의된 전파 상수를 epsilon-negative(ENG) 물질 (${\varepsilon}'<0,\;{\mu}'>0$), mu-negative (MNG) 물질 (${\varepsilon}'>0,\;{\mu}'<0$), 그리고 double-negative (DNG) 물질 (${\varepsilon}'<0,\;{\mu}'<0$)으로 확장하여 유도하였다. 이와 함께 유전율 손실(${\varepsilon}"$)과 투자율 손실(${\mu}"$)이 전파 상수에 미치는 영향을 분석하여 이 물질에서 전파가 right-handed (RH) 혹은 left-handed (LH)로 동작하는지를 규명하였다. DPS와 DNG 물질은 ${\varepsilon}"$와 ${\mu}"$의 값에 상관없이 각각 RH 그리고 LH 매질로 동작한다. 반면 ENG와 MNG 물질은 (${\varepsilon}'{\mu}"+{\varepsilon}"{\mu}'$)의 부호가 양수이면 RH, 음수이면 LH 매질로 동작하는 특이한 특성을 가진다.
