Background: Presenteeism is closely related to work performance, work quality and quantity, and productivity at work. According to the job demand-control-support model, job demand, job control, and support play important roles in presenteeism. The present study investigated job characteristics profiles based on the job demand-control-support model and identify the association between job characteristics profiles and presenteeism. Methods: This secondary data analysis used the Sixth Korean Working Condition Survey, a nationwide cross-sectional dataset. The study included 25,361 Korean wage workers employed in the workplace with two or more workers. Participants were classified into four job characteristics profiles based on the job demand-control-support model, using latent profile analysis, and logistic regression was performed to examine the association between study variables. Results: Overall, 11.0 % of study participants reported experience of presenteeism in the past 12 months. Age, sex, location, monthly income, shift work, work hours, health problems, and sleep disturbances were significantly associated with presenteeism. The rate of presenteeism was the highest in the passive isolate group. The passive collective, active collective, and low-stain collective groups had a 23.0%, 21.0%, and 29.0% lower likelihood of experiencing presenteeism, respectively, than the passive isolate group. Conclusions: The job demand-control-support profiles and the risk of presenteeism were significantly associated. The most significant group that lowered the experience of presenteeism was the low-strain collective group, which had a low level of demand and high levels of control and support. Therefore, we need a policy to reduce job demand and increase job control and support at the organizational and national levels.

Problem-Based Learning(PBL) is one of constructionism's model which is learner-centered learning. In this paper, a role-play base PBL using character is proposed to study importance of information security. It is different from the other PBL models in that it reflects the characteristics of learners, learning task. And it is learning support system which the learners preside their own learning activities using Internet and mobile devices. By experimental result showed that proposed method was more effective than traditional teacher-oriented teaching method about information security in self-directed learning, cooperative learning, contents-making and attraction.

The purpose of this study is to produce an essential guideline for making costumes for traditional Korean mask plays by doing a comparative analysis between traditional Korean mask plays and Italian 'Commedia dell'arte'. The results of this study are as follow. The costumes of Korea's mask plays were mainly used to show difference in social status. Analysis showed that costume features, such as color, fabric, and silhouette, were not important to the traits of the character. On the other hand, the costumes in the Italian 'Commedia dell'arte' were used to express the characters' traits. The colors, fabric and silhouettes were exaggerated compared to everyday wear. This enhanced the looks of the character, and it kept on developing with the demands of the culture consumer. This study was performed to support further development and success of traditional Korean mask plays.

This paper is to recognize and play tab chords from guitar musical sheets. The musical chord area of an input image is segmented by changing the image in saturation and applying the Grabcut algorithm. Based on a template matching, our approach detects tab starting sections on a segmented musical area. The virtual block method is introduced to search blanks over chord lines and extract tab fret segments, which doesn't cause the computation loss to remove tab lines. In the experimental tests, the prototype based classification outperforms Bayesian method and the nearest neighbor rule with the whole set of training data and its performance is similar to that of the support vector machine. The experimental result shows that the prediction rate is about 99.0% and the number of selected prototypes is below 3.0%.

Industrial IoT applications, including smart factories, require two problem-solving to build data monitoring systems required by services from distributed IoT sensors (smart sensors). One is to overcome proprietary protocols, data formats, and hardware differences and to uniquely identify and connect IoT sensors, and the other is to overcome the problem of changing the server-side data storage structure and sensor data transmission format according to the addition or change of service or IoT sensors. The IEEE 1451.4 standard-based or IPMI specification-based smart sensor technology supports the development of plug-and-play sensors that solve the first problem. However, there is a lack of research that requires a second problem-solving, which requires support for the plug-in of IoT sensors into remote services. To propose a solution for the integration of these two problem-solving, we present a IoT sensor platform, a service system architecture, and a service plugin protocol for the MQTT-based IIoT application environment.

The Yangbanchum was reconstructed based on mask play that had been handed down in Goseong, Gyeongsangnam-do, Korea. Talnori, called Goseong Ogwangdae, is a Korean folk cultural heritage designated as National Important Intangible Cultural Property No. 57. This mask play provides catharsis to the audience by unraveling the hypocrisy and lies of the aristocrats through satire and humor. Our performance team, the ensemble Better Than Medicine (eBTM) used a large fan (Boochae)to create a performance that blew away anxiety and pain. Watching this performance, the performer and the audience feel the consensus of sharing emotions and send strong bonds and support to each other. This study provides that Yangbanchum dance promotes the mental health by feeling emotional sharing through vicarious satisfaction and mirror effect.

This study explored the moderating effects of self control and social support in terms of the relationship between stress and problem behaviors of children of divorced single parent families according to gender. A questionnaire was administered to elementary school-aged children (grades 3-6). 266 children from divorced single parent families were surveyed. The major findings were as follows : first, self control had a moderating role to play in the relationship between stress and problem behaviors for girls. Second, social support also had a moderating effect in the relationship between stress and problem behaviors for boys. Third, the variables having a moderating effect in the relationship between stress and problem behaviors of children also differed according to gender. Therefore differences in gender should be considered when seeking moderating the relationship between stress and problem behaviors of children.

The purpose of this study was to evaluate the childcare support demonstration services and direct policy. The participants for the study were three childcare (IDOLBOMI), three parents who were provided with IDOLBOMI, two practitioners, and three professors related to IDOLBOMI. The data was collected by interview and a phone survey and analyzed qualitatively. The results and several suggestions were follows: First, IDOLBOMI loved to take care of children, felt proud of the job, and thought the work was worthy. The result can help future IDOLBOMI when they are recruited and trained; Second, IDOLBOMI wanted income security at least, which means that the basic activity fee for the IDOLBOMI should be compensated by government; Third, most of the parents who experienced the service were generally satisfied with that, but they wanted the quality of nutrition, hygiene and the quality of play to be developed for children. Therefore, the management of the center and maintenance of education are needed constantly for the IDOLBOMI system; Fourth, the parents who needed the service thought the cost of IDOLBOMI was expensive. Expenditure support should be sought for the parents; Finally, the group of professionals had difficulty in securing the quality of childcare support services. For the future, it is necessary to increase the educational budget, manpower resources, and PR budget for IDOLBOMI.
