Purpose: This study was conducted to generate a grounded substantive theory of the adaptation process of mothers-in-law of Vietnamese women married to Korean husbands. Methods: Thirteen women who had Vietnamese daughters-in-law were interviewed. Data were transcribed verbatim and analyzed using a grounded theory method. Results: Eight categories with 19 sub-categories were extracted from 268 concepts. The identified phenomenon was 'overcoming differences' and the core category was 'trying one's best to live together with daughter-in-law'. The 9 categories were grouped into 3 stages for the adaptation process: encountering, struggling, and living together. Conclusion: The results indicate that when individuals from different cultural and personal backgrounds have to live together there is a continuing negotiation process towards meeting each other's needs. Health professionals can assist this adaptation process by providing these women with insights into various ways of meeting each other's need while they are struggling.

An archive system is designed to store data for a long time without loss. However, many important factors such as temperature, dust, vibration, and humidity must be considered to design a successful archive system. Read/write devices, for example optical disk drives(ODDs), in an archive system generate heat while they are in operation. Fans are usually used to remove heat but the air flow accompanies dust into the system result in system failure. In this study, an archive system with six ODDs is chosen as an analysis model and flow together with temperature distributions are computed using a CFD simulation package. Flow analysis is focused on four cooling fans at the rear panel and temperature distribution is studied for various cases of fan operation. From the temperature point of view, fans give significant effects on $4^{th}$ to $6^{th}$ ODDs compared to the $1^{st}$ to $3^{rd}$ ODDs. Also, it is noticed which fan is the most important as far as cooling is concerned.

This paper proposes a multiobjective model describing the trade-offs involved in selecting the locations of drop-off boxes for collecting used products and transporting these products to designated locations. We assume the following reverse flow of used products. Owners of used products (cellular phones, digital cameras, ink cartridges, etc.) take them to the nearest drop-off box when the distance is reasonably short. We also assume that owners living closer to drop-off boxes dispose of more used products than do owners living farther from drop-off boxes. Different types of used products are collected, with each type requiring its own drop-off box. A transportation destination for each product is specified. Three objectives are considered: maximizing the volume of used products collected at drop-off boxes; minimizing the cost of transporting collected products to designated locations; and minimizing the cost of allocating space for drop-off boxes. We formulate the above model as a multiobjective integer programming problem and generate the corresponding set of Pareto optimal solutions. We apply the model to an area using population data for Chofu City, Tokyo, Japan, and analyze the trade-offs between the objectives.

A facility layout design (FLD) problem can be generally introduced as assignment of facilities (departments) to a site such that a set of criteria are satisfied or some objectives are minimized (maximized). Hence, it can be considered as a multi-criteria problem due to the presence of qualitative criteria such as maintenance or flexibility and quantitative criteria such as the total cost of handling material. The VIKOR method was developed to solve multiple criteria decision making problems with conflicting and non-commensurable (different units) criteria, assuming that compromising is acceptable for conflict resolution, the decision maker wants a solution that is the closest to the ideal, and the alternatives are evaluated according to all established criteria. This paper proposes a hierarchical analytic hierarchy process (AHP) and VIKOR approach to solve the FLD problem. A computer-aided layout-planning tool is adopted to generate the facility layout problems, as well as their quantitative data. The qualitative performance measures are weighted by AHP. VIKOR is then used to solve the FLD problem. Finally, the proposed integrated procedure is applied to three real-time examples.

Micro hydraulic turbines take a growing interest because of its small and simple structure as well as high possibility of applying to micro and small hydropower resources. The differential pressure exiting within the city water pipelines can be used efficiently to generate electricity like the energy generated through gravitational potential energy in dams. In order to reduce water pressure at the inlet of water cleaning centers, pressure reducing valves are used widely. Therefore, pressure energy is wasted. Instead of using the pressure reduction valve, a micro counter-rotating hydraulic turbine can be replaced to get energy caused by the large differential pressure found in the city water pipelines. In this paper, detail studies have been carried out to acquire basic design data of micro counter-rotating hydraulic turbine, output power, head, and efficiency characteristics on various number of runner vane. Moreover, the influences of pressure, tangential and axial velocity distributions on turbine performance are also investigated.

This study aims to test the influence of employee competency and career management on career commitment in Indonesia. The study uses the cross-sectional data of regional government employees collected from February to April 2020. Regression and structural equation modeling are employed. The results base on the effect of employee competency and career management on career commitment in Indonesia are in line with the existing theory (i.e., Bandura's Career Theory). Employee competency has a significant positive influence on career management and career commitment, which shows that regional government employees with high competency generate effective career management, and in turn career commitment increased. Regional governments with their career management program should formulate human resources management practice policy (e.g., career support, training, career development program, and orientation programs) in order to increase their competency. The positive effect of employee competency on career management is because of the effective training and career development program. The positive influence of career management on career commitment is due to the regional government providing an attractive career program, thus, employees' career commitment improved. The positive influence of employee competency on career commitment via career management is implemented by regional government support to improve the career management program.

Though their activities, companies have an impact on environmental problems and nature conservation. The accounting sector can play a role in environmental conservation efforts related to environmental costs, and the implemention of the Corporate Sustainability Management System (CSMS) could be a key factor that can improve the company's financial performance. This study aims to determine how green accounting through the application of CSMS can improve the financial performance of manufacturing companies in Indonesia, a developing country. The sampling method used was purposive sampling, while the research sample consisted of 38 companies that had followed PROPER and were indexed on the IDX. Data were analyzed using the Structural Equation Modeling (SEM) method known as the Partial Least Square (PLS) method. The results of this study indicate that manufacturing companies in Indonesia are able to implement green accounting by allocating appropriate environmental costs by earmarking a portion to carry CSMS implementation so as to improve financial performance. People in Indonesia consider that manufacturing companies that have good company rankings in the evaluation program for company performance ratings in environmental management run by the Indonesian Ministry of Environment are in a position to generate customer loyalty, especially in financial performance.

Behaviors of organizational members can be classified as two types. One is behavior required to perform formally given job. The other is a various kind of behavior taken voluntarily but not required directly and formally to perform job. The former can be called as in-job behavior while the latter can be called as extra-job behavior. Many organizational scientists so far, have focused on investigating in-job behavior. Yet, from a decade, organizational researchers have recognized that in-job behavior alone can not explain sufficiently job performance or organizational effectiveness Thus. they have paid attention to extra-job behavior, which is generally called as organizational citizenship behavior. Existing studies of organizational citizenship behavior have three types : First type is studying the concept and components of organizational citizenship behavior. Second tope is studying the determinants of organizational citizen-ship behavior and relationships with it. And third type is studying relatioships between organizational citizenship behavior and job performance. This study, therefore, have purposes as follows : Firstly, this study designs a comprehensive model in the below figure and generates inclusive hypotheses about relationships among antecedents, intermediate factors, and the components of organizational citizenship behavior. Secondly, this study investigating empirically such relationships and draws a picture of mediation roles of the intermediate variables. To design the model and generate the hypotheses, this study conducted a comprehensive literature survey on organizational citizenship behavior. To test the hypotheses, this study collected data from 847 employees at 12 large genral hospitals in Pusan area through a questionnaire survey and conducted the three step mediated regression analysis using the SAS-PC Package.

Applying human engineering simulation to analyzing work capability and movements of operators during manufacturing is highly demanded. However, difficulty in modeling digital human required for simulation makes engineers to be reluctant to utilize human simulation for their tasks. This paper addresses such problem on human engineering simulation by developing the technology to automatize human modeling with multiple Kinects at different depths. The Kinects enable us to acquire the movements of digital human which are essential data for implementing human engineering simulation. In this paper, we present a system for modeling automation of digital human. Especially, the system provides a way of generating the digital model of workers' movement and position using multiple Kinects which cannot be generated by single Kinect. Lastly, we verify the effects of the developed system in terms of modeling time and accuracy by applying the system to four different scenarios. In conclusion, the proposed system makes it possible to generate the digital human model easily and reduce costs and time for human engineering simulation.
