Purpose: This study was describes the development and implementation a sex education program with a blended learning method for university students. Methods: Sixty-eight university students were recruited either to the experimental group (n=35) or the control group (n=33). This program was developed based on the analysis, design, development, implementation, and evaluation model. The analysis phase consisted of a literature review, focus group interview, expert consultations, and target group survey. In addition, learning objectives and structure were designed, and a printed text-book, presentation slides, cross-word puzzle, and debate topics were developed. In the implementation phase, the program was conducted 3 times over the course of 3 weeks. The evaluation phase involved verification of the effects of the program on sex-related knowledge, sexual autonomy, and justification of violence, as well as an assessment of satisfaction with the program. Results: The experimental group had significantly higher scores on sex-related knowledge (t=5.47, p<.001), sexual autonomy (t=2.40, p=.019), and justification of violence (t=2.52, p=.015) than the control group. Conclusion: The results indicate that this sex education program with blended learning was effective in meeting the needs of university students and can be widely used in this context.

Purpose - The intent of this research is to discover the factors that enhance innovative work behaviors of group members in order to strengthen the competitiveness of small enterprises. In addition, we verify that employee job characteristic factors have an influence between antecedent variables and dependent variables in the work situations at small companies. Research design, data, and methodology - This study is focused on identifying the factors, such as self-efficacy, leader member exchange (LMX), and collective efficacy, which promote innovative work behaviors. A total of 305 valid questionnaires were collected. Results - The results of a path analysis showed that LMX did not have significant effects on task significance, and autonomy did not have significant effects on innovative work behavior. Conclusions - These findings of the study imply that even though leaders supported the groups in accordance with official procedures by placing group members within or outside certain groups, task identity perceived by group members was not impacted. In addition, autonomy given to those with relatively less capability might be a burden rather than a positive outcome.

Unmanned military vehicles (UMVs) will be increasingly applied to the various military operations. These UMVs are most commonly characterized as dealing with "4D" task - dull, dirty, dangerous and difficult with automations. Although most of the UMVs are designed to a high degree of autonomy, the human operator will still intervene in the robots operation, and tele-operate them to achieve his or her mission. Thus, operator capacity, along with robot autonomy and user interface, is one of the important design factors in the research and development of the UMVs. In this paper, we propose the method to assess the operator capacity of the UMVs. The method is comprised of the 6 steps (problem, assumption, goal function identification, operator task analysis, task modeling & simulation, results and assessment), and herein colored Petri-nets are used for the modeling and simulation. Further, an illustrative example is described at the end of this paper.

Work-related musculoskeletal disorders (WMSDs) have become a hot issue in the Korean workplace for the past several years. So many manufacturing companies have tried to improve the work environments for the control and the prevention of the WMSDs. This study investigates the relation between WMSDs and job stress from 965 workers in a shipbuilding company by questionnaire analysis. The seven job stress factors which are job autonomy, job insecurity, organizational system, workplace culture, unfair compensation, relationship conflict, and job requirement were analyzed. The prevalence of musculoskeletal disorders symptoms were 12.9%. The analysis showed that job stress by job autonomy was higher than that by job stress factor. WMSDs were associated with job requirement, organizational system, unfair compensation and workplace culture. The results could be used to design the management program for the reduction of job stress.

Objectives: An increase in the number of caregivers is necessary to provide services to the elderly, but more importantly, it is qualitative management for them. The purpose of this study was to identify occupational stress, job satisfaction, and organizational commitment and to explore the impact of occupational stress on job satisfaction and organizational commitment among caregivers employed in health service centers for the elderly. Methods: This descriptive survey was a cross-sectional correlational design of 118 caregivers. The questionnaire included occupational stress, job satisfaction, and organizational commitment. Stepwise multiple regression was applied. Results: Job satisfaction and organization commitment of caregivers were found to be above the average. There was a high level of job stress due to lack of job autonomy, job demands, and inadequate compensation. It has been found that the inappropriate compensation, organization system, work culture, and lack of job autonomy affected job satisfaction of caregivers. The factors affecting organizational commitment were inadequate compensation, job insecurity, and work culture. Conclusions: Efforts should be made to assess and complement the appropriateness of compensation and work culture that are taken to relieve job stress to enhance the job satisfaction and organizational commitment of caregivers.

For the vast majority of geostationary satellites currently in orbit, station keeping activities including orbit determination and maneuver planning and execution are ground-directed and dependent on the availability of ground-based satellite control personnel and facilities. However, a requirement linked to satellite autonomy and survivability in cases of interrupted ground support is often one of the stipulated provisions on the satellite platform design. It is especially important for a geostationary military-purposed satellite to remain within its designated orbital window, in order to provide reliable uninterrupted telecommunications services, in the absence of ground-based resources due to warfare or other disasters. In this paper we investigate factors affecting the robustness of a geostationary satellite's orbit in terms of the maximum duration the satellite's station keeping window can be maintained without ground intervention. By comparing simulations of orbit evolution, given different initial conditions and operations strategies, a variation of parameters study has been performed and we have analyzed which factors the duration is most sensitive to. This also provides valuable insights into which factors may be worth controlling by a military or civilian geostationary satellite operator. Our simulations show that the most beneficial factor for maximizing the time a satellite will remain in the station keeping window is the operational practice of pre-emptively loading East-West station keeping maneuvers for automatic execution on board the satellite should ground control capability be lost. The second most beneficial factor is using short station keeping maneuver cycle durations.

This study desires to examine the impact of five dimensions of entrepreneurial (EO) orientation (innovation, competitive aggressiveness, proactiveness, risk-taking, autonomy) on the operation of women-owned SMEs; the author conducted a case study in Vietnam. How will each dimension of EO affect women-owned SMEs' performance? This study aims to seek the answer to these questions. A survey research design and a theoretical framework have been developed for all factors in the current context. A simple random sampling technique was applied in 300 SMEs in some provinces of Vietnam through a survey questionnaire, and a total of 258 valid responses were assessed as appropriate. The obtained data was analyzed by using SPSS 20.0. Cronbach's α test and factor analysis have been carried out to test the reliability of data and validate the hypothesis. Research results show that innovation, competitive aggressiveness, proactiveness, and autonomy positively affect business performance, while risk-taking negatively affects business performance. The results suggest that female business owners should know how to improve each dimension of the entrepreneurial in line with its context. Research results are important implications for Government administrative agencies for businesses to consult and introduce effective support policies. It is recommended that similar studies be replicated to confirm this result.

The purpose of this study is to discuss the current status and limitations of convergence education in universities and to explore new possibilities of engineering convergence education by analyzing characteristics and cases of self - design semesters as convergence education. As a result of this study, it was found that the education for fostering convergence ability is insufficient for the viewpoint of education. The types of convergence education could be classified into three categories. However, the concept and paradigm of convergence education has not been established precisely because it is made in a 'top-down' manner by the government. In addition, there was a limit of the lack of a foundation to operate the convergence education. However, A university's self-design semester, it shows the possibility of cultivating the overall convergence ability by giving autonomy and subjectivity to learners and through the acquisition of contextual knowledge and the ability of collaboration.

Exterior wall molding, which is widely applied as a design element of the exterior wall of domestic apartment, should be applied as a nonflammable or semi-nonflammable material grade according to the rules on standards for evacuation/fire protection structures of buildings. For this reason, stone and AL sheet are mainly used, but stone is expensive and design autonomy is low. Inorganic reinforced CLC nonflammable molding was applied to the exterior wall of the building through tests of nonflammable performance, noise reduction, and installation stability.
