The purpose of this study is to demonstrate the antecedent and consequential factors of satisfaction with the flexible working system. Organizational culture was examined as an antecedent factor, while job satisfaction, work performance, organizational commitment, turnover intention, and quality of life were examined as outcome factors. The data of 2,785 public officials who used the flexible work system in the Korea Institute of Public Administration (2022) data set were analyzed using SPSS 28.0. and PROCESS macro's Model 4. The main research findings are as follows. First, organizational cultures that respect individuality and cooperation, supports management, and aims for work autonomy all positively and significantly affect satisfaction with the flexible working system. When ranking the size of influence by the type of organizational culture, work autonomy, respect for individuality, and a cooperative organizational culture had a positive impact in that order, with work autonomy being the most influential factor. In addition, the public officials' age, job preparation period, self-evaluation of workload, and overtime working hours are significant antecedents of satisfaction with the flexible work system. Second, when examining consequential factors, a high level of satisfaction with the flexible working system affects job satisfaction (+), work performance (+), organizational commitment (+), turnover intention (-), and quality of life (+). Job satisfaction was an especially valid mediator between satisfaction with the flexible working system and other consequential factors, including work performance, organizational commitment, turnover intention, and quality of life.

With the development of Information Communication Technology and a way of solving problems such as productivity improvement, advanced working attitude, greenhouse gas reduction, low birth rate, aged problem, etc., the need of smart work is increasing. Getting out of legacy working types that are limited in time and space, the flexible seat system at a smart work center that supports the smart working environment is proposed. However, the seat choice based on employee's emotional judgement may cause the decline of forming cooperative space and mutual communication because of the scattered seat arrangement between employees. This paper proposed a seat recommendation method for the mutual cooperation at a smart work center. The method is based on a work similarity of employees. A prototype system also implemented to show the feasibility.

In this research, we observed the co-works among novice and expert science teachers who were involved in a science teacher association and explored their interactions. The science teacher association is K-12 science teachers' gathering near Seoul. This study is a case study with the participant observation and the private interview of 8 novice teachers and 3 expert teachers. Based on the collected data, interaction between novice and expert teachers was categorized as seven types; question and answer, demonstration, presentation, co-working, providing materials, listening, and showing interest. Several factors supporting such an active interaction were derived from this study; 1) Teachers perceived well about the importance and the merits of co-working with other science teachers. 2) The open and cooperative environment of the science teacher association supported teachers' interaction. 3) There were tasks that teachers needed to co-work such as the science fair and the science camp. 4) There were opportunities of interactions for publishing books and developing modules. 5) Lots of expert teachers were willing to help and co-work with novice teachers. We found that novice teachers could continue to grow in terms of the professional development under interactive, continuing and cooperative environment with expert teachers.

The performance of stilting engine, in particular, its energy conversion efficiencies are critically influenced by the regenerator characteristics. The regenerator characteristics are influenced by effectiveness, void fraction. heat transfer loss and fluid friction loss in the regenerator matrix. These factors were influenced by the surface geometry and material properties of the regenerator matrix. The regenerator design goals arc good heat transfer and low pressure drop of working Bas across the regenerator. Various data for designing a wire screen matrix have been given by Kays and London(1984). The mesh number of their experiment. however, was confined below the No. 60. which seems rather small for the Stirling engine applications. In this paper. in order to provide a basic data for the design of regenerator matrix, characteristics of heat transfer and flow friction loss were investigated by a packed mettled of matrix in oscillating flow as the same condition of operation in a Stirling engine. Seven kinds of sing1e wire screen meshes were used as the regenerator matrices. The results are summarized as follows; 1. While the working fluid flew slowly in the regenerator. the temperature difference was great at the both hot-blow(the working fluid flows from healer to cooler) and cold-blow(the working fluid flows from cooler to healer). On the other hand. while the working fluid flew fast. the temperature difference was not distinguished. 2. The No.150 wire screen used as the regenerator matrix showed excellent performance than tile others. 3. Phase angle variation and filling rate affected heat transfer or regenerator matrices. 4. Temperature difference between the inlet and outlet of the regenerator is very hish in degree of 120 phase angle.

Background: The concept of social capital has its focus on cooperative relations in the workplace. This study investigates the association between social capital and sickness absence among workers in 41 work groups in the Danish dairy industry and examines the possible effects of an intervention on social capital in the workplace on sickness absence. Methods: A sample of 791 dairy workers working in 41 work groups that participated in an intervention study on social capital filled in a questionnaire on four subtypes of social capital, and social capital scores from individual participants were aggregated to the level of work groups. Sickness absence was measured at the level of work groups in company registers as the two-year average percentage of working time lost to sickness absence. Group-level associations between social capital and sickness absence were analyzed using multilevel linear regression analysis. Analyses were adjusted for age, gender, group size, and random effects at the workplace level. Results: We found statistically significant associations between social capital within work groups, social capital in relation to the immediate manager, and social capital toward the workplace as a whole on the one side and sickness absence on the other side. We found no support for any effects of the intervention on sickness absence. Conclusion: The work group level of social capital is associated with the work group level of sickness absence. However, the intervention to enhance group-level social capital had no effect on reducing sickness absence in the intervention group.

Previously, ASCI(Automation System for Curtain-wall Installation) which combined with a multi-DOF manipulator to a mini-excavator was developed and applied on construction site. As result, the operation by one operator and more intuitive operation method are proposed to improve ASCI's operation method which need one person with a remote joystick and another operating an excavator. The human-robot cooperative system can cope with various and untypical constructing environment through the real-time interacting with a human, robot and constructing environment simultaneously. The physical power of a robot system helps a human to handle heavy construction materials with relatively scaled-down load. Also, a human can feel and response the force reflected from robot end effecter acting with working environment. This paper presents the feasibility study regarding the application of the proposed human-robot cooperation control for construction robot through experiments on a 2DOF manipulator.

Purpose - The purpose of this paper is to discuss success factors behind ATO distribution channels by examining successful partnerships between producers and alternative trading organizations (ATOs). Research design, data, and methodology - This is a case study, an analytical approach, which illustrates how the partnership between producers and ATOs has strengthened the fair trade and the performance of participants in the trade based on the example of the trading relationship between Beautiful Coffee, an alternative trading organization dealing coffee related products, and the coffee cooperative union (CCU), a coffee producing cooperative in Gulmi, Nepal. Results - Beautiful Coffee in the partnership with HELVETAS empowered small coffee farmers by a successful institutionalization of CCU that consolidated the distribution channel to be more efficient. Also, Beautiful Coffee and its partnership with KOICA have tried to increase productivity and quality of coffee beans. Conclusions - The case of Beautiful Coffee demonstrates that the partnership between producers and alternative trading organizations (ATOs) has benefited the fair trade partners. In other words, Beautiful Coffee's partnerships with a NGO working in the local producing area, HELVETAS, and a government aid agency, KOICA could strengthen the relationship between the producers and the ATO, and thus contributes to the whole distribution channel.

Purpose: The purpose of this study was to investigate factors affecting turnover intention in pediatric nurses. Methods: A survey was conducted with 212 nurses working in pediatric units at 15 hospitals in Busan, K city. Data were collected from September 1 to October 31, 2014. and analyzed with SPSS PASW 18.0. Results: In Stepwise multiple regression analysis, factors affecting the nurses' turnover intention were emotional burnout (${\beta}$ =.37, p<.001), relationship between nurse and doctor (${\beta}$ =.20, p<.001), turnover plan (${\beta}$ =.17, p<.001), and annual salary (${\beta}$ =-.13, p<.001), and these variables accounted for 32.2% of the variance in turnover intention. Conclusion: The findings indicate that the major factors influencing pediatric nurses' turnover intention are emotional burnout, cooperative relationship between nurse and doctor, turnover plan, and annual salary. Thus, in order to reduce pediatric nurses' turnover intention, it is necessary to develop intervention programs to prevent emotional burnout, the most influencing factor, and enhance cooperative relationship between nurse and doctor and to examine their effects.
