Field works are decreasing gradually since advancement of industrial robots. Tunnel cleaning is a dangerous field work which can be solved only by introducingadvanced tunnel cleaning automation equipment. Industrial robots work tirelessly night and day without a loss in performance. Consequently, greatly reduce the costs of manufactured goods.So far only 200 construction robots are invented. Robots used for tunnel cleaning are not of high standard they always need additional workers for job to be done. Robots offer specific benefits to workers, industries and countries. If introduced correctly for tunnel cleaning, industrial robots can improve the quality of life by freeing workers from dirty, boring, dangerous and heavy labor. Development of advanced tunnel cleaning automation equipment is a must to overcome above issues. The benefits of robots to industry include improved management control, productivity and consistently high quality products. This research is a study on tunnel cleaning automation equipment and introducing advanced tunnel cleaning automation equipment.

The serving temperature control practices were assessed in 20 general hospital's dietetics utilizing centralized or decentralized tray assembly systems. The results of the study were summarized as follows : 1) All of the surveyed hospitals were utilizing conventional foodservice system. The number of dietary employees per bed was very low when comparing with that in America. Working hours of employees per week were approximately two times greater than those in America. 2) When comparing two tray assembly systems, dietary labor hours and costs in centralized system were less than those in decentralized system. 3) When comparing serving temperature practices between two tray assembly systems, the temperatures of meals utilizing centralized tray service were significantly lower than those in decentralized system, and only the steamed rice served in decentralized system was within the acceptable temperature range. 4) There was no significant difference in sensory acceptance scores marked by patients served by two different types of tray assembly systems. The serving temperature was significantly correlated to the patient's overall acceptability.

In this research endeavor, we engaged with 70 construction safety specialists from established construction firms through surveys and interviews. The primary aim was to dissect and understand the weight and ramifications of specific cost items within the Occupational Safety and Health Management Funds(OSHMF) and Safety Management Expenses(SME). From our analysis, salient insights emerged. Within the realm of OSHMF, the cost items associated with safety facilities and the remunerations of safety managers were identified as paramount. It was observed that there are marked variations in the perceived significance and repercussions associated with diverse cost items of OSHMF. In stark contrast, when assessing the SME, the nuances in perceived weight and consequences of individual cost items were relatively muted, suggesting a more uniform viewpoint among the experts. Furthermore, our research probed the interrelationship between the significance and repercussions within OSHMF and SME domains. Notably, OSHMF manifested a positive linear relationship, suggesting that cost items of higher importance invariably had a more pronounced effect. On the other hand, the SME showcased a more subtle association, hinting at intricate underlying dynamics. The outcomes of this investigation are poised to offer instrumental guidance for enhancing safety protocols and diminishing accident occurrences in domestic construction undertakings.

Diligence/Indolence records are the key data for a human resource management and the basic data to measure the salaries of the employees. However, existing mechanical or electro-magnetic diligence/indolence management systems have the problems that the systems are often incorrect or require much cost to build them. In this paper, we design and implement the diligence/indolence management system using a smart device of an employee. To measure the data of the diligence/indolence, the implemented system acquires the location data of the employee using the MAC addresses of both a smart device and access points of the WiFi and transfers the data of punching-in/out based on the acquired location to a server. The benefit of the proposed system is that it is easy for small business to use the proposed D/I management system with low cost because the system exploits smart devices and WiFi access points installed previously.

Abundance of low-wage labor resources, strategic location connecting East-West Asia and business professionals are fluent in English are strength of Bangladesh. Also the business environment changes in China such as the wage increases and labor regulations enhancement acts as searching for replacement of investment where Bangladesh is considered as substitute. At this point there is a need for research of Bangladesh employees at human resource management level. Therefore this study focus on the research of an important component of human resource management, organizational commitment. This study analysis the Bangladesh employees organizational commitment and its antecedent. This study consider four antecedents, role ambiguity, role conflict, voluntary participation and the work centrality and three organizational commitment, affective organizational commitment, continuous organizational commitment and normative organizational commitment. As results show, role ambiguity and role conflict has a negative influence on affective organizational commitment. And voluntary participation and work centrality give positive influence. Role ambiguity showed a negative effect on continuous organizational commitment, however role conflict show positive effect. Voluntary participation and work centrality showed positive effect on normative organizational commitment and role ambiguity showed negative influence. Results of this study give clue to understand Bangladesh employees organizational commitment and its relation among variables. And thus the need for appropriate management presented.

Social enterprises can be identified roughly as social purpose-oriented business ventures. They often fill the gaps left by governmental and commercial ventures in providing for certain vulnerable sectors of society. Though social enterprises often adopt market mechanisms in their organizational structures, their emphasis on particular social outcomes means that they intentionally pursue double/triple-bottom lines, thus distinguishing them from many traditional for-profit businesses. Among the Korean laborers, women have been hardest hit by the global economic crisis. As the movements have substantially been taken to strengthen women's economic activities in the recent years, many policies are formulated with these trends, connecting women's employment with social enterprises. This study focused on analyzing social enterprises to be friendly and to provide decent work to women. Data were collected from 491 social enterprises and 830 workers. The main results are as follows. First, the women's employment in social enterprises has accounted for a relatively high rate and the women's wage also is similar to men's one. Second, as for work conditions and types, most women have preferred irregular and non-managerial work. Thus, social enterprises have showed a positive response for the women's job opportunities, while social enterprises have had a negative one for enhancing the women's status at the labor market. In conclusion, social enterprises should institutionalize how to provide more stable working condition to women and to improve their's capacity.

This research was conducted to investigate the prevalence of depression and convergent factors related to depression in male and female wage workers. Using data from the 2014 and 2016 Korea National Health and Nutrition Examination Survey, 3,763 adults (1,888 males, 1,875 females) between the ages of 19 and under 65 were analyzed. Depression was measured by the Patient Health Questionnaire-9 (PHQ-9), and the depression (PHQ-9≥10) of all workers was 4.1% (3.2% for men, 5.0% for women). Multiple logistic regression analysis was performed to evaluate the depressive factors of male and female wage workers. In male workers, work-related characteristics such as employment type and working hours per week were found to be significantly related to depression even after adjusting for socio-demographic characteristics, health-related characteristics, and life style characteristics. However, in female workers, work-related characteristics did not expose a significant relationship, showing a difference from male workers. Therefore it is necessary to develop and implement workplace counselling or mental health promotion programs that take into account the gender characteristics of depression risk factors. Also, as health-related characteristics (diagnosis of depression, suicide plan, perceived stress level, unmet medical services, self-rated health status) were found to be related to depression for both male and female workers, continuous management of these factors is required.

It has been widely-reported that the quality of life in Korea is lower than that of the economic growth. In particular, construction managers are reported to have a lower quality of life compared to people in other job types due to the specific nature of the tasks they have to carry out. These include early work attendance time and fewer holidays. In this respect, the aim of this study is to analyse construction managers' requirements on work-life balance. The results showed that the working hours of construction managers were long and their leisure hours were shorter. The requirements for work-life balance were in the order of non-working time, working time, salary, and job security. The requirements by group showed a statistically significant difference in work hours. The requirements on the shortening of work hours were highest in the group of "section chiefs and deputy heads" and lowest in the group of "department heads" and up. It is hoped that the results of this study will be used as basic data for future government-level policy making and construction companies' business directions in relation to the improvement of workers' work-life balance.
