Previous studies on emotion have repeatedly suggested that alexithymia is an important predictor of depression. Therefore, this study examined whether the relationship between these two variables can be moderated by personality factors, focusing on the Big five personality traits. An online survey of 312 college students, including alexithymia, depression, and Big five personality traits (Extraversion, Agreeableness, Conscientiousness, Emotional Stability, and Openness to Experience) was conducted. As the results, as expected, alexithymia predicted depression, which was in line with the existing research flow. In addition, moderation analysis revealed that agreeableness, emotional stability, and openness to experience moderated the relationship between alexithymia and depression, while extraversion and conscientiousness did not. This study has an important implication in that it discriminated which specific personality traits function as moderators in the process of increasing depression due to alexithymia.

This study aims to analyze the effects of infants' attachment to their mother and child care teacher on their adaptation to child care. Data were collected in a purposive sample involving 100 infants and toddlers at age one and two, their mothers, and 36 teachers were analyzed with two-way ANOVA. The results showed that the effects of infants' attachment to their mother and teacher varied by subfactors of adaptation. 'Social Relationships' and 'Positive Emotion' were significantly different only among infants who established insecure attachment with their mother. Second, the level of 'Social Relationships' and 'Positive Emotion' were significantly high when teacher-infant attachment was secure among infants who established insecure attachment with their mother. Third, there were significant effects of mother-infant attachment on 'Aggressive Behavior' as infants who established insecure attachment with their mother showed a significantly higher level of 'Aggressive Behavior' than infants having secure attachment with their mother.

In order to maximize customer satisfaction and provide differentiated customer-oriented marketing strategies, it is important to understand the essence of consumer behavior and characteristics of their market segmentation. Therefore, this study explored the relationships among five different food-related lifestyle (i.e., health, fashion, taste, economy and safety oriented), positive emotion, and satisfaction. An analysis of 338 samples drawn from college students who visited coffeehouse at least once in the previous months was performed. The results revealed that, taste, economy, and safety oriented lifestyle significantly affected positive emotion, and positive emotion significantly affected satisfaction. The findings highlight the significant role of coffeehouse customer food-related lifestyle toward positive emotion in the formation of satisfaction, and therefore generate theoretical and practical implications for the coffeehouse industry.

This study examines the degrees of criminal investigators' job satisfaction and organizational commitment and investigates which factors determine the variations in them. In the first step of analysis, independent variables of criminal investigators' job satisfaction consist of work itself, achievement, responsibility, safety, stability, interpersonal relations, recognition, supervision, and opportunity of growth. In the second step, job satisfaction is a mediating variable and organizational commitment is a defendant variable. Organizational commitment is classified into three types - "affective", "continuance" and "normative". According to the structural equation model analysis, responsibility has a great influence on job satisfaction, and job satisfaction affects affective commitment and continuance commitment. This study suggests that job satisfaction should be increased to improve criminal investigators' organizational commitment. And responsibility is necessary for the improvement of job satisfaction. Despite the professional detective system operating in Korea since January 1, 2005, the level of criminal investigators' recognitions of safety, stability and opportunity of growth turn out to be low. Based on these findings, this study presents four ways to reform measures which are listed below. First, to improve a! n economical circumstance of criminal investigators, any expense associated with criminal investigation should be paid by organizations. Second, to improve safety of criminal investigators, it is necessary to develop and supply enough police equipments. Third, criminal investigators' working hours should be shorten. Fourth, to improve criminal investigators' responsibilities, criminal investigators should be allowed to conduct criminal investigation independently from the prosecution.

This study identified heart response of participants while listening to sounds which have 1/f fluctuations with exponent ${\alpha}$ gradient. The participants were engaged in emotional stress work. Prior studies related to 1/f fluctuation sound have reported that sound source can alleviate psychological and physiological state of users. Subjects of this study were exposed to sound with three levels of ${\alpha}$ gradient. Heart response of subjects were measured with Photoplethysmography(PPG) sensor simultaneously. The dependent variables of this study were beat per minute(BPM), very low frequency percent of pulse rate variability (VLF percent), the standard deviation of all normal RR intervals (SDNN), and high frequency power(HF power). Subject showed arousal response when exposed to sound with exponent ${\alpha}$ gradient of 3 whereas the sound with exponent ${\alpha}$ gradient of 1 and 2 resulted in relax effect. The characteristic of 1/f fluctuation sounds can be applied to alleviate stress for employers under emotional labor.

쾌적한 음환경을 창조하기 위해서는 무엇보다도 음이 갖는 심리적 속성과 인지구조 를 파악하는 것이 중요하다. 이 연구는 여러 가지 환경음중에서 유쾌음에 대한 심리적 속성, 그리고 그 속성과 음과의 관계를 정성적으로 파악하는데 목적을 두고 있다. 특히, 음에 대한 감정 및 정서표현에 사회문화적 차이가 있다는 점을 감안하여 한국어 표현어를 심층적으로 조사·분석하고, 36종류의 표현어와 34종류의 유쾌음에 대해서 평정척도법을 이용한 심리평 가 실험을 실시하였다. 실험의 분석결과, 유쾌음의 심리적 속성은 활동성, 안정성, 박력성의 3가지 요인이 중요한 요인으로 밝혀졌다. 또한, 음과 표현어사이의 관계를 파악하기 위해 다 차원척도법을 이용한 선호도분석에 의해서 3가지 요인과 음과의 관계를 파악해 보았다. 이 결과는 유쾌음에 대한 평가시 중요한 심리적 속성으로서, 음의 물리적 평가방법 및 음환경 의 쾌적성 창조를 위한 중요한 실마리를 제공해 줄 수 있을 것이다.

Blockchain technology fulfills the reliance requirement and is now entering a new stage of performance. However, the current blockchain technology has significant disadvantages in scalability and latency because of its architecture. Therefore, to adopt blockchain technology to real industry, we must overcome the performance issue by redesigning blockchain architecture. This paper introduces several element technologies and a novel blockchain architecture TPAC, that preserves blockchain's technical advantage but shows more stable and faster transaction processing performance and low latency.

In the modern society, psychological diseases and impulsive crimes due to stress are occurring. In order to reduce the stress, the existing treatment methods consisted of continuous visit counseling to determine the psychological state and prescribe medication or psychotherapy. Although this face-to-face counseling method is effective, it takes much time to determine the state of the patient, and there is a problem of treatment efficiency that is difficult to be continuously managed depending on the individual situation. In this paper, we propose an artificial intelligence emotion management system that emotions of user monitor in real time and induced to a table state. The system measures multiple bio-signals based on the PPG and the GSR sensors, preprocesses the data into appropriate data types, and classifies four typical emotional states such as pleasure, relax, sadness, and horror through the SVM algorithm. We verify that the emotion of the user is guided to a stable state by providing a real-time emotion management service when the classification result is judged to be a negative state such as sadness or fear through experiments.
