In the present work, an approach for the multiple time probabilistic characterization of the response of linear structural systems subjected to random non-Gaussian processes is presented. Its fundamental property is working directly on the multiple time probability density functions of the actions and of the response. This avoids of passing through the evaluation of the response statistical moments at multiple time or correlations, reducing the computational effort in a consistent measure. This approach is the extension to the multiple time case of a previously published dynamic Probability Transformation Method (PTM) working on a single evolution of the response statistics. The application to some simple examples has revealed the efficiency of the method, both in terms of computational effort and in terms of accuracy.

The purpose of this study is to provide the basic information for the improvement of housewives consciousness and satisfaction of household work by analyzing the data regarding the housewives consciousness and satisfaction toward household work. The research problems was described as follows; 1) How independent variables influence the housewives consciousness of household work. 2) How independent variables influence the satisfaction of household work. 3) How relate the housewives consciousness and the satisfaction of household work. The research was conducted on 354 housewives in Seoul during the end of January and the beginning of March, 1986. As for the measurement of the instrument, questionnaire with 46 items was made by investigator. The data were analyzed by frequency, percentage, mean and t-test, F-test, Scheffe-test, Pearson-r. The results were summarized as follows; 1) Among the independent variables, the ages of housewives, durations of marriage, psychologica satisfaction were variables to have influence on the housewives consciousness towark household work. 2) Among the independent variable,s the socio-economic status, durations of marriage, psychological satisfaction were variables to have influence on the satisfaction of household work. 3) There were strong positive correlationship between the housewives consciousness and the satisfaction of household work. As a result, it is necessary to minimize the repetition and the overload of house-hold chores through the rationalization of household work and also to divide householdwork properly to family members. We let the housewives feel that her ability can be obtained from the household work. Especially the housewives must have a clear and a high level of consciousness of the household work an expect to receive high value of her household work from the family members. In order to do so, it seems to be important that housewives makes on great effort to have a positive value system and attitudes toward the consciousness and satisfaction of household work. We also must develop those factors through school and home education.

Objectives: The purpose of this study was to examine the differences of dental hygienists in how they view their work and how they rate their emotional labor and occupational stress. Gathering this data was an effort to provide information on how to increase occupational satisfaction and improve work environments for dental hygienists. Methods: We analyzed data collected from 178 dental hygienists. The dental hygienists were randomly selected by convenience sampling from dental hospitals. Results: Our results showed that pediatric hygienists had more negative responses in regard to their views on their work. As for emotional labor, dental hygienists from pediatric dental clinics experienced heavier emotional labor than those from general dental clinics. On the other hand, dental hygienists from general dental clinics suffered more from occupational stress than pediatric dental hygienists did. Conclusions: Given the findings of this study, effective and ideal programs that promote occupational satisfaction for dental hygienists should be prepared, and strategies should be developed to resolve emotional labor and improve their work environments, as well.

The paper examines the determinants of employee engagement in the not-for-profit organization (NFPO) sector. A structured questionnaire survey of 205 NFPO employees in Vietnam was employed, preceded by in-depth interviews with NFPO associates and managers. After a multiple regression analysis to study the impact of five independent variables on one dependent variable, the study reveals that Work design and Work-life balance are positively and significantly associated with employee engagement. Of which, Work design is measured by the level of job fit, job autonomy, job challenge, and job meaningfulness. On the other hand, Work-life balance involves measurement aspects consisting of how reasonable the workload is and organizational support. Meanwhile, different from the business world, Leadership, Learning and Development, and Recognition do not show statistically positive impacts on employee engagement in NFPOs. Still, they are crucial back-supporting factors to ensure employee experience at work. Further, the study finds that personal growth contributes a great part to keep employees in the sector motivated. This paper brings the area of study to the forefront in an effort to benefit the practice of human resources management in NFPOs as well as support employees in the sector with a higher quality working experience.

Importance of quality control is gradually increasing in the construction. And the reber work is very important things which influence in safety and durability of the building and accounts for about 9.8% of the total cost. Although reber work is important, quality control of the rebar work is still performed by attitude and experience of worker. Therefore, it is very important to quality achievement effort and quality standards recognition of rebar worker for quality sophistication in the construction. Some papers have dealt with the quality control in construction. But there was no study for actual conditions of quality standards recognition of rebar workers. The purpose of this study is to survey the actual conditions of quality standards recognition of rebar workers and to analyze difference of consciousness of administrator and worker. The result are : there id difference of consciousness of worker and administrator, workers work without knowing quality standard.

Previous work measurement methods need much time and effort of time study analysts because they have to measure required time through direct observations. In this study, we propose a method which efficiently measures standard times without involvement of human analysts using digital image processing techniques. This method consists of two main steps: motion representation step and cycle segmentation step. In motion representation step, we first detect the motion of any object distinct from its background by differencing two consecutive images separated by a constant time interval. The images thus obtained then pass through an edge detector filter. Finally, the mean values of coordinates of significant pixels of the edge image are obtained. Through these processes, the motions of the observed worker are represented by two time series data of worker location in horizontal and vertical axes. In the second step, called the cycle segmentation step, we extract the frames which have maximum or minimum coordinates in one cycle and store them in a stack, and calculate each cycle time using these frames. In this step we also consider methods on how to detect work delays due to unexpected events such as operator's escapement from the work area, or interruptions. To condude, the experimental results show that the proposed method is very cost-effective and useful for measuring time standards for various work environment.

An increasingly important facet of software development is the ability to estimate the associate cost and effort of development early in the development life cycle. Most of the proposed models are based upon a combination of intuition, expert judgement, and regression analysis of empirical data. Overall, the work has failed to produce any single model that can be applied with a reasonable degree of success to a variety of environments. This paper presents a neural network (NN) model that related software development effort to software size measured in function element types. The heuristic approach is applied to decide the number of hidden neurons in NN from the relationship between input-output pairs. The research describes appropriate NN modeling in the context of a case study for 24 software development projects. Also, this paper compared the NN model with a regression analysis model and found the NN model has better accuracy.
