In addition to physical risks such as electrical, chemical, and mechanic ones in the workplace, psychosocial risks are also raising as an important issue in recent years in connection with human rights and work-life balance policies. The purpose of this study is to confirm the degree of effect of the psychosocial risk management plan at the workplace on workers through logistic regression analysis. Input data for logistic regression analysis is the results of a survey of 4,558 people conducted by the Institute for Occupational Safety and Health were used. There are 9 independent variables, including the change a workplace and confidential counseling, and the dependent variable is whether the worker feels the effect on the psychosocial risk management plan. As a result of this study, changes in work organization, dispute resolution procedures, provision of education program, notification of the impact of psychosocial risks on safety and health, and the persons in charge of solving psychosocial problems are shown effective in reducing worker's psychosocial risks. This study drives which of the management plans implemented to reduce the psychosocial risk of workers in the workplace are effective, so it can contribute to the development of psychosocial risk management plans in the future.

The purpose of this study is to investigate the current status of work performance of public health doctors(PHDs) involved in quarantine of COVID-19, and to suggest a plan to support PHDs for effective national epidemic prevention and control in the future. As a result of the study, it was found that PHDs mainly performed sample collection, interview, and treatment. 39% of PHDs worked in places without negative pressure facilities, and personal protective equipment and welfare support were poor. In addition, it was investigated that they experienced high-risk infectious diseases, mental distress, exclusion from the decision-making process, conflicts with officials, problems with work guidelines, and lack of prior education. For effective infectious disease management, it is necessary to assign appropriate ranks and to participate in the decision-making process for quarantine, to specify appropriate compensation and regulations, to education, and to support mental health.

This study aims to discover an effect of conflicts between work-family family-work of hotel employees on their emotional exhaustion through an empirical analysis, and to propose relevant implications. Also, the study tried to identify which role a responsive strategy may play as a moderating variable from among such influential factors. In consideration of the sales and the number of rooms at hotels as of 2010, the study conducted survey research about seven hotels located in Seoul, and carried out research with 298 copies of effective samples. In order to confirm the effect of work-family family-work on emotional exhaustion, the study undertook a multiple regression analysis and performed a moderated regression analysis for confirming the moderation effect of a responsive strategy. As a result, only the conflicts between one's work and a family had a significant effect on emotional exhaustion, and a problem-oriented responsive strategy demonstrated a moderation effect of the conflicts between work-family family-work and emotional exhaustion. In this regard, hotels should be prepared with a system which enables hotel chefs to be more faithful to both their families and household affairs through the reasonable operation of workload or an instructive system at work, and it would be possible to deal with the symptom of emotional exhaustion by conflict management through a rational analysis of the cause of conflict, if any, as well as through an alternative to such a conflict.

Crack in Pavements have been continually increased aby water penetration Therefore, the cracks can result in deterioration of the pavements that could be extremely dangerous fro road users. Creak sealing work performed in outdoor is very dangerous, costly and labor intensive. To slove these problems, automated crack sealing systems have been developed. it Would be needed that work information related to crack sealing must be gathered in an effort to used for existing or future crack sealing work. Furthermore, work information related to crack sealing could be utilized in analyzing work productivity and condition. The primary objective of this study is to propose a PDA and Web-based system for work information management of crack sealing which enables to effectively interchange work information between head office and fieds, and to accurately collect work information. Finally, it is anticipated that the effective use of the developed PDA and web-based system would be able to effectively share work information, measure productivity, estimate costs as well as plan future work schedule.

There exists a limitation to provide proper advance information for safe maneuvering through guidance and caution signs in freeway mobile work zones, unlike fixed work zones. Although a work-protection vehicle is currently deployed at the rear of the work vehicle, more active countermeasures to prevent crashes are required. The purpose of this study was to propose a method to evaluate the safety in mobile work zones and to present effective countermeasures. Driving simulation experiments were conducted to analyze characteristics of driver's behavior in mobile and fixed work zones. Safety distance index (SDI) based on the comparison of stopping distances of a work-protection vehicle and a following subject vehicle was used to evaluate traffic safety. More dangerous driving behavior was observed in the mobile work zone. Especially, it was identified that the lane-change of vehicles following the work- protection vehicle was late. Therefore, it is necessary to actively introduce methods to provide warning information so that the driver can recognize the work-protection vehicle in advance and carry out appropriate evasive maneuvers.

Working the night-shift and long working hours may be linked to insomnia. The purpose of this study is to determine the association between night-shift work and long working-hours with regard to subjective insomnia in Korean workers. This study was based on the Third Korean Working Condition Survey (KWCS) conducted on workers in 2011. The total number of individuals included in the analysis was 34,708 workers. Adjusted odd ratios showed statistically effective associations to insomnia. For night-shift work, the results were 2.71 (1.53 - 4.82) for night shift work by experts and managers, 2.95 (2.11 - 4.11) for night-shift work by officers, and 3.90 (2.05 - 7.42) for night-shift work by engineers compared with day duty. For long working hours, the scores were 2.43 (1.68-3.51) for >52 working hours by officers, 1.72 (1.15 - 2.58) for those in sales and service compared to ${\leq}40$ working hours. We suggest the need for Korean workers to target specific groups when creating policies related to reasonable environmental conditions.

Traffic safety in freeway work zones is of keen interest since both crash frequency and severity are much higher than those in general freeway sections. The lane closure in work zones results in greater work load of drivers due to compulsory lane changes and speed reduction. Therefore, traffic merging control is an effective countermeasure for enhancing work zone safety. This study proposed an integrated framework based on driving and traffic simulations to evaluate traffic merging control methods in terms of traffic safety. In addition to the conventional merging method using the taper, joint merge and chicane-type merge were evaluated by the proposed methodology. Chicane-type merge outperformed other methods under level of service (LOS) A and B. On the other hand, it was identified that joint merge showed the best safety performance under LOS C traffic conditions.

The study examined work and family life of married women employed in a manufacturing industry. Data were gathered from the use of face-to-face interview method from a sample of 230 married working women. The major findings of this study can be summarized as follows: (1) Most of the respondents found the work repetitive and unappealing, with the double burden of a paid work and housework. Thus, it is necessary for the government to implement social policies for married working women, such as establishment of various child care centers, part-time jobs, and dissemination of egalitarian sex-role attitudes. (2) More than half of the respondents were born in rural areas and immigrated to the urban sectors, forming a nuclear family structure. Most of these women were married with love, but some of them could not have a marriage ceremony because of the economic reasons. Thus, it may be necessary to increase the service centers to offer a free marital ceremony. (3) About 30% of the respondents answered they left their preschool aged children unattended, after dismissing from a kindergarden on a private institution. It was shown that working women, even though they were in charge of child-rearing, did not have an effective mechanism to control or protect their children while they were away from home. Most of them frequently used material compensations from their children in order to make up their absence at home. (4) It was found that the strategy for working women to decrease a dual-role conflict is to make a hierachy on the work they to do and to do only basic housework for everyday life and to do the rest of work on a off-day.

This study aims at applying Photoshop functions to digital make-up(DM) for aging effect based upon the knowledge of phrenology, comparing the result with that of the real or off-line make-up(OM) and identifying any possible difference between two methods: which contributes to understanding the potential and problems of DM at application level. This study aims at suggesting a method to apply computer graphics(CGs) to special effect make-up for aging effect through a case, contributing to attracting academic concerns and building theoretical frameworks for DM. It used 'Aging Process' in Adobe Photoshop CS4 Extended(CS4E) to change a young girl into a senior lady. In the process of DM, the study applies various tools and methods to making face wrinkled, finds the most effective way among them for each area of face, suggests a method to integrate the ways and shows the result of the method. Compared with OM, DM using CS4E is the less constrained work regarding procedure and time. Specifically, it can save the time tremendously because the reiterative operation of work can be omitted, when the same work is repeated, using 'Action' function which memorizes the history of the work. Once a DM work is produced, since it is durable, reusable and convertible to various images with additional operations, it seems very economical as well as highly promising to market the work through on-line sales. Regarding face features and skin, it reviewed literature in make-up and phrenology while it used Photoshop CS4 Extended tools to demonstrate a case of aging effect by combining and painting pictures of a young lady and a senior citizen.
