Purpose: This study was conducted in order to the relationship between life satisfaction, health behaviors, and successful aging and factors associated with successful aging. Methods: Participants in this study included 159 elders living in one city. Data on life satisfaction (Choi's Life Satisfaction Scale for Korean elderly, 1984), health behaviors (Choi & Kim's Health Behaviors Scale for Korean elderly, 1997), and successful aging (Kim & Shin's Successful Aging Scale for Korean elderly, 2005) were collected by trained interviewers. For analysis of collected data, the PASW 18.0 program was used, which included descriptive analysis, t-test, ANOVA, Scheffe test, Pearson correlation coefficients, and Multiple regression. Results: Results showed a positive correlation between life satisfaction, health behaviors, and successful aging. Life satisfaction, self-perceived health status, and health behavior explained 60.8% of successful aging. Conclusion: There is a need to help improve health behavior and self-perceived health status of elders. We should also understand life satisfaction over their life span and establish a program that encourages healthy behavior in the community. Accordingly, these efforts will allow for achievement of a more successful aging process for the elderly.

This study aimed to elucidate the relationship between theoretical parameters affecting the coagulation process and the real coagulation phenomenon applied to the dye wastewater. Emphasis was placed on the effective removal of the suspend particulates. Parameters studied in this study are pH, coagulant concentration and surface potential. Optimal dosages of coagulants by the measurement of the zeta potential at lower then $25^{\circ}C$ are 5\times$10^P-3}$ M of $FeCl_3 and 1.4\times10^{-6}M of Fe_2(SO_4)_3$. The results were well agreeded with the separate Jar-test results. Emphasis was also placed on the relationship between water quality and the content of SS. It was found that the COD and DOC were reduced to 65% and 85%, respectively. The turbidity at the above condition was reduced from 300 NTU to 0~1 NTU. Efforts were made to clarify the behavior of the suspend solid as affecting the water quality. 12,000~13,000 particles/10mL in $1~50\mu$m size range particulates in the raw wastewater were reduced to 300 particle/10mL in the same range after treatment. This research has proposed the methodology to find out the optimal condition of coagulation for small scale wastewater treatment plant or chemical coagulation process.

Purpose: Hope has been identified as a protective factor that contributes to achieving a better quality to life, especially in patients with chronic disease. The purpose of this review was to synthesize current knowledge about the relationship between hope and quality of life among adolescents living with chronic illnesses. Methods: We searched major English-language databases (PsycINFO, PubMed, and CINAHL) for studies from January 1, 2002 to July 12, 2019. Studies were included if they provided data on hope and its relationship with quality of life among adolescents with chronic diseases. Results: In total, five articles were selected from the 336 studies that were retrieved. All five studies reported a positive correlation between hope and quality of life, such that people with a higher level of hope had a better quality of life. Hope was found to have direct and indirect effects on quality of life in adolescents with chronic diseases. Conclusion: Healthcare professionals should make more efforts to enhance hope in adolescents with chronic diseases in order to improve their quality of life. Future studies exploring how hope develops in adolescents with chronic diseases and the long-term impact of hope on quality of life are necessary.

The interface system, GIS-AGNPS was to be validated with field data from six tested small watersheds ranging from 0.7 to 4.7$km^2$ in size which have steep topography and complex landuses. The model validation involved the calibration of input parameters and component modifications, in efforts to develop a model applicable to general uses for identifying and controlling nonpoint source pollution loads from agricultural watersheds. The simulated direct runoff from AGNPS was in good agreement with the field data for the averaged antecedent moisture conditions or AMC- II. The results differed, however, from the observed for AMC- I or III. A simple empirical relationship was proposed to estimate the curve number for AMC- I or m from AMC- II, which was found to result in simulated runoff close to the observed. The peak runoff relationship at AGNPS was also modified to reflect the watershed conditions and tested satisfactorily with the field data. The simulated sediment yields from the watersheds were fair as compared to the observed. Nutrient loads simulated from the model were different from the observed data. It appeared that the model was incapable of adequate depicting nutrient transport processes at paddy field and other landuses of the tested watersheds. Some modifications may be needed for the accurate representing the processes at paddy field.

The effective case depth for case-hardened rolling bearing has been discussed. For this purpose, rolling contact fatigue tests for ball bearings built with inner race of various hardness values were conducted until L₁₀ calculating rating life using a bearing life test machine under radial loading. Then, the distribution of residual stress below the inner raceway, which depended on the hardness value, was measured by X-ray diffraction. As a result, the linear relationship was established between the hardness value of the inner race and the theoretical shear stress evaluated at the depth where the residual stress disappeared below the inner raceway. Based on the relationship, it could be found that the factor of safety in bearing manufacturer’s rules for the effective case depth of case hardened rolling bearings was set higher. However, it could be also found that the hardness values at the depth where the maximum shearing stress acted below the raceway surface in a tapered roller bearing hardened by the carburizing process, were not sufficient for preventing plastic deformation under the basic dynamic load rating. Consequently, further efforts were still required to reduce or to disperse the contact load on the material design of a rolling bearing in order to prolong its life.

Purpose - This study traces the determinants of key account management performance in the garments industry in Bangladesh. The key account management approach involves significant challenges for marketers to manage their strategically important customers and use this approach as a strategic weapon in their selling efforts. This study examines three categories of determinants of key account management performance including operational variables, organizational variables, and relational variables by exploring data from 100% export oriented readymade garments companies in Bangladesh. Research design, data, and methodology - Data were collected from 30 readymade garments manufacturers, considering a company as a unit of analysis. Using the data, instrument validity and reliability and, subsequently, data normality were examined using the Statistical Package for the Social Sciences (SPSS) software to isolate the important determinants of key account management performance. Results - The instruments are reliable and the data are reasonably normal. Conclusion - The study explored and validated the adapted instruments of various operational, organizational, and relational antecedent factors of key account management performance, most of which were thus far ignored.

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.

This study was designed to evaluate the current orientation and further to develop an effective orientation curriculum of new nurses by analyzing questionraire taken from 45 numbers of all nurses who have worked for 18 months below at one hospital located in C city on July, 1995. The results obtained are summarized as follows. 1. The subjects showed the high necessity of "emergency nursing", "cardiopulmunary resuscitation", "disinfection and infection" and "interpersonal relationship" in order, but relatively low necessity of "doctor supports" and "medical insurance affair" for the practical orientation. Therefore, the orientation should provide prepondently an education Which they really need, on the basis of their education experiences and/or requirements. 2. Practical training, individual teaching and performance will be an effective orientation more than theorical education. The educator should be selected from unit based persons being capable of providing technical education to trainee. Also, in order to develop the teaching method and to improve the corresponding ability, a special program is required for educators. 3. It will be desirable that task training is given at least one month before working at their unit. In addition, orientation schedule should be made to concentrate trainee on their task training fully. 4. The subjects showed that half of them had spent four to six months for work adaptation. A meeting of new nurses may be helpful not only to acclimate themselves to new circumstances. but also to provide an exchange of views and an emotional relationship. Furthermore, unit based staffs should exerts efforts to maintain the educational circumstances and warm concern for new nurse's adaptation.
