This study is about the development of a system related to the CATV network. It intends to develop an automatically centralized Headend system and a distributive system to remove the ineffectiveness of the established manual system. To achieve this goal, we took a part of bandwidth, which is not used for the transmission of video signals in the established frequency bandwidth, and used it for the transmission and receiver and a automatic distributive system. We developed an information management system for the 9600bps CATV using RS-232 of forward/backward communication and backward communication. Based on window, It consist of ID generation, transmitter/receiver, control and backup part.

Social justice has been an interest of whole geographers for almost four decades. The conception of social justice includes fairness and equity in the distribution of a wide range of attributes. The purpose of this study is to understand social justice in geography of welfare. The theories of social justice are needed to describe relationship between social justice and geography of welfare. The evaluation of spatial variations in welfare is closely associated with social justice. Equality, equity, efficiency, and fairness are the reasonable criteria to apply to the evaluation of distributions of welfare, relating to distributive(or territorial) justice. However, there are complications in the spatial application of welfare evaluation criteria, including access across space, boundary crossing and ecological fallacy.

In order to study the degradation and damage behaviors of steel frame welded connections, two series of tests in references with different connection constructions were carried out subjected to various cyclic loading patterns. Hysteretic curves, degradation and damage behaviours and fatigue properties of specimens were firstly studied. Typical failure modes and probable damage reasons were discussed. Then, various damage index models with variables of dissipative energy, cumulative displacement and combined energy and displacement were summarized and applied for all experimental specimens. The damage developing curves of ten damage index models for each connection were obtained. Finally, the predicted and evaluated capacities of damage index models were compared in order to describe the degraded performance and failure modes. The characteristics of each damage index model were discussed in depth, and then their distributive laws were summarized. The tests and analysis results showed that the loading histories significantly affected the distributive shapes of damage index models. Different models had their own ranges of application. The selected parameters of damage index models had great effect on the developing trends of damage curves. The model with only displacement variable was recommended because of a more simple form and no integral calculation, which was easier to be formulated and embedded in application programs.

This study aims to explore the relationship between organizational justice and social loafing of organizations in Ho Chi Minh City through quantitative analysis from the survey data for the 228 employees are working at the Organizations in Ho Chi Minh City. The instrument of collecting data was a questionnaire. The collected data were analyzed using SPSS version 22 and employing exploratory factor analysis (EFA), Cronbach's alpha, multiple regression analysis. The results showed that only two factors are Distributive justice and Procedural justice is to have the reverse effect on social loafing of employee. From the results of the study showed, Distributive justice and Procedural justice has the opposite effect of social loafing, which demonstrates that when individuals feel that their work is spent on Perform tasks in a clearly divided and they will receive a worthwhile result in the group when performing the task then the individual's collective indifference to the organization will decrease. And motivate the employee to make more efforts to work and contribute for the organization. In addition, the factor of Procedural justice also has the opposite effect of collective redundancy, which demonstrates that employees are more concerned about fairness in official policies and organizational procedures.

The purpose of this study is to develop instruction model of environmental problem process focused with environmental justice. This study has analyzed environmental problem solution process in social studies of elementary school from 4th grade to 6th grade with it. The results of this study are as follows. First, social studies of elementary school didn't show distributive justice in environmental problem solving process. Second, procedural justice existed, but offered information is lacking to each main group. Third, substantive justice was emphasized personal viewpoint. We developed instruction model of environmental problem solving process based upon the results. Component of instruction model is problem analysis, distributive justice, procedural justice, substantive justice and evaluating a solution. Timely, teachers can use and can apply it in social studies class. In conclusion, it is strongly recommend to teach environmental education linked with environmental justice. It enables us enhance a new awareness and attitudes towards sustainable development.

The Purposes of this study ar (1) to identify types and levels of channel conflicts between an apparel manufacturer and a franchised agency, (2) to investigate the effect of economic dependence on conflicts, and (3) to examine the effect of conflicts on satisfaction in a franchised agency's perspective in distributive channel of Korean apparel industry. For this study, questionnaires were administered to the owner or manager of 300 franchised agencies. Employing a sample of 209, data were analyzed by using means, factor analysis, pearson correlation and multi-regression analysis. Major findings are as follows: 1) Types of conflicts between apparel manufacturers and franchised agencies are identified as goal divergence, difference in perception, ineffective communication and lack of role clarity. The highest level of conflicts are lack of role clarity, followed by goal divergence, difference in perception and ineffective communication. 2) Economic dependence leads to channel conflicts in part. Greater levels of economic dependence foster greater conflicts such as lack of role clarity and lower conflicts such as ineffective communication. 3) With respect to effect of conflict on satisfaction, the greater the levels of conflict, the lower the degree of satisfaction with ole performance and with business decision and overall satisfaction.

We analyzed the non-Newtonian and non-isothermal flow with Carreau-Yasuda viscosity model in co-rotating and counter-rotating twin screw extruder systems. The mixing performances with respect to the screw speed, the screw pitch, and the rotating direction have been investigated. The dynamics of mixing was studied numerically by tracking the motions of particles. The extent of mixing was characterized in terms of the deformation rate, the residence time distribution, and the average strain. The results showed that the high screw speed decreases the residence time but increases the deformation rate. Small screw pitch increases the residence time. It is concluded that the high screw speed increases the dispersive mixing performance, while the small screw pitch increases the distributive mixing performance. Co-rotating screw extruder has the better conveying performance and the distributive mixing performance than counter-rotating screw extruder with the same screw speed and pitch. Co-rotating screw extruder developed faster transport velocity and it is advantageous the flow characteristics to the mixing that transfers polymer melt from one barrel to the other barrel.

The focus of this study was on service recovery process of domestic internet fashion shopping mall, the purposes of this study were to extract perceived interaction effort and service justice with the recovery factors according to service failure by literature review, and to empirically examine the effect this variables on customer satisfaction with complaint handling and loyalty. The questionnaires was administered to 256 internet shopping mall customer, who has experiences of dissatisfaction and complaining behavior after buying fashion products. The data was analyzed by Cronbach's a, confirmatory factor analysis, correlation analysis, and structural equation modeling using LISREL 8.30 program. The results were as follows. First, perceived interaction partly affected serviced justice consumer. Interaction effort on the part of consumer negatively affected interactional justice, but didn't affected distributive justice and procedural justice. However interaction effort on the part of shopping mall positively affected all justice. Second, distributive, procedural and interactive justice positively affected customer satisfaction with complaint handling and loyalty. Finally, customer satisfaction with complaint handling positively affected customer loyalty. The implications of the research and directions for future researchers were discussed.

This study analyzed the main effect on organizational commitment of organizational justice factors and the moderating effects of appraisal instrumentality on the relationship of three justice factors(distributive Justice, procedural justice, and interactional justice) and organizational commitment. Hypotheses were tested by surveying 468 employees of four universities. This results suggest following important implications. First, all three justice factors are essential to enhance the level of organizational commitment in appraisal about employee of university. Second, especially, the moderating effect of appraisal instrument has been found only between distributive justice and organization commitment.
