This study aims to derive key construction supervision work that can be digitalized among construction supervision work. The scope of the study includes domestic construction sites to which the Building Act of South Korea is applied. First, the construction supervision process was identified through extensive consultation of construction expert witnesses. Afterwards, the key construction supervision works for digitization were derived through survey results construction expert witnesses. Among the 24 supervision works throughout the pre-construction, construction, and post-construction stages, the proportion of supervision work manpower or cost, the type of data generated by supervision work and the urgency of introducing digital technology, and the impact on productivity and safety of supervision work were evaluated on a 5-point scale from "very low" to "very high" was investigated. The survey was conducted by t-test analysis, and as a result, it was possible to derive that the level of digitization was higher than average in "quality management," "safety management," and "collection and cooperation of maintenance instructions." It can be interpreted that digitization has been introduced on a pilot testing basis or has already been completed according to the needs of the site. On the other hand, it can be interpreted that the work that are obtained below the average score are considered to be realistically constrained at the construction site and that it is inevitable for the supervisor to proceed manually. Future studies include analyzing the quantitative impact of the key construction supervision work once digitalization is fully applied.

The parameters of PID controller should be readjusted whenever system character change. In spite of a rapid development of control theory, this work needs much time and effort of expert. In this paper, to resolve this defect, after the sample of parameters in the changeable limits of system character is obtained, these parametrs are used as desired values of back propagation learning algorithm, also neural network auto tuner for PID controller is proposed by determing the optimum structure of neural network. Simulation results demonstrate that auto-tuning proper to system character can work well.

The purpose of this study is to examine the effects of work value of vocational counselors on organizational commitment and the mediating effect of job satisfaction. For this aim, this study conducted a survey concerning vocational counseling, work value, organizational commitment and job satisfaction targeting 207 vocational counselors in the Jeonbuk region. Analysis results found higher work value of vocational counselors resulted in higher organizational commitment. Second, concerning the relationship between work value and organizational commitment of vocational counselors, job satisfaction showed a significant mediating effect. Furthermore, in accordance with the type of work value, the relationship between organization commitment and both inherent and extrinsic work value had significant mediating effects on job satisfaction. Through this, the study confirmed that when vocational counselors recognize not only the inherent value of work is high, but also the extrinsic value such as benefits that could be obtained socially and economically through job, it is more likely to lead to increased organizational commitment. In particular, it was confirmed that extrinsic value is relatively more influential on job satisfaction and organizational commitment compared with inherent value. This indicates the importance of improving extrinsic value, such as material compensation and job stability, as well as inherent value, such as confidence and pride about the job, for increasing job satisfaction and organizational commitment.

Since Deng Xiaoping's implementation of the "One China, Two Systems" policy, mainland China and the other Chinese regions of Hong Kong and Macau have cooperated in various ways to work towards successfully developing China's overall economy and industries. Particularly, cooperation between Guangdong Province and adjoining Hong Kong have been contributing to China's development, and this study explores their industry conditions including their current two governments policies designed to promote collaboration. The two partners were in a cooperative relationship even before the handover of Hong Kong, beginning with a "front shop, back factory" model built on their respective comparative advantages in labor-intensive industries in the 1980s. This cooperation effectively propelled the Pearl River Delta Region's industrialization process and enabled Hong Kong to transform from a manufacturing industry-based economy to a service industry-based economy. From the early 2000s, Guangdong and Hong Kong diversified their collaboration project from culture to high-tech. Also, both authorities produced several types of policies not only to promote both industries but also to harmonize their two different economic levels and models. As a result, the Guangdong and Hong Kong economies have developed remarkably well during the past two decades and continue to form future plans that carry plenty of optimism. Nonetheless, this study showed discrepancies between engineers and scientists from the two areas in their perception of their technology and science cooperation. Hong Kong experts were more negative in their responses but noted some successes of the collaboration, while Guangdong's group showed overall positive responses. This difference results from an unbalanced role in cooperation. Hong Kong's side responds to cooperation plans and takes on leading roles with more frequency than Guangdong's side in actual cooperation project processes.

The government intends to pursue a program to develop LINC from 2012. Through this program, the government intends to nurture expert manpower required by the areas of industry, research and development, and technology transfer. For this, it wants to create and expand various leader models of industry-university cooperation. Therefore, this study is focused on the method of developing a robust curriculum suitable for educating students to a level where they are ready to work upon graduation. In this study, curriculums used by some universities which have been taken part in the program of industry-university cooperation have been examined. As a result there are some suggestions for the future of this curriculum, and they are as follows: firstly, in order to overcome the gap between universities and industries, universities should survey the requirement of local industries and apply this to developing a curriculum for industry-university cooperation; secondly, DACUM should be used and finally, the curriculum for industry-university cooperation should build upon a stepwise-model in the form of a foundation-core-intensification course throughout a student's university years.

Both coordinated multi-point transmission and frequency reuse are effective approaches to mitigate inter-cell interference and improve network coverage. The motivation of this work is to explore the manner to effectively utilize the spectrum resource by reasonably combining cooperation and frequency reuse. The $Mat{\acute{e}}rn$ cluster process, which is appropriate to model networks with hot spots, is used to model the spatial distribution of base stations. Two cooperative mechanisms, coherent and non-coherent joint transmission (JT), are analyzed and compared. We also evaluate the effect of multiple antennas and imperfect channel state information. The simulation reveals that the proposed approach to combine cooperation and frequency reuse is effective to improve the network coverage for users located at both the center and the boundary of the cooperative region.

We develop a theoretical framework for international cooperation that can be used for the elimination of asbestos-related diseases(ARDs). The framework is based on the similarities in the temporal patterns of asbestos use and occurrence of ARDs in diverse countries. The status of each nation can be characterized by observing asbestos use and ARD frequency therein using a time window. Countries that supply technology for prevention of ARDs can be classified as donors and countries that receive these technologies as recipients. We suggest identification of three levels of core preventative technologies. Development of a common platform to gather and manage core preventative technologies will combine the strengths of donor countries and the needs of recipient countries.

This study examined the effects of work values and the career decision level on the major commitment of the university students majoring in social welfare. For this purpose, a survey of 351 undergraduate students majoring in social welfare at 4 universities located in Kangwon-do was conducted and the data were analyzed. The work values consisted of intrinsic values and extrinsic values. The career decision level was measured by the career decision scale (CDS) and the major commitment was measured by the flow state scale (FSS). The research findings are as follows. First, the career decision level (3.43) and major commitment (3.58) of the university students majoring in social welfare were slightly higher than the mid-point on the 5 point Likert scale. In addition, the intrinsic work value (4.05) were higher than the extrinsic work value (3.34). Second, the intrinsic work values and career decision level were positively correlated with the major commitment. Third, the extrinsic work value had a negative effect on the major commitment (${\beta}=-.34$, p<.001); however, the intrinsic work value (${\beta}=.31$, p<.001) and career decision level (${\beta}=.18$, p<.001) had a positive effects on the major commitment. This paper also discusses the theoretical and practical implications for university student's work values, career decision level, and major commitment based on the research findings.

This study examined the effects of ego-resilience and emotional labor on work-family conflicts among middle-aged female workers. Data were collected through self-reported structured questionnaires of 148 middle-aged female workers from October 2, 2013 to April 10, 2014. The results suggest that the mean score of work-family conflict was 25.59 (SD=11.99) and there were significant differences in living arrangements (F=4.32, p=.015), monthly living expenses (r=.18, p=.028), and job satisfaction (F=6.33, p<.001) by work-family conflict. Work-family conflict was negatively related to ego-resilience (r=-.28 p=.001). Living arrangement (living with parents, children) (${\beta}=.29$, p=.045), monthly living expenses (${\beta}=.22$, p=.006), job satisfaction (${\beta}=-.20$, p=.015), and ego-resilience (${\beta}=-.28$, p<.001) were identified as significant predictors of work-family conflict. This model explained about 19.0% of work-family conflict in middle-aged female workers (F=6.61 p<.001). Therefore, as a strategy to reduce the level of work-family conflict in middle-aged female workers, it is necessary to consider socioeconomic factors such as living arrangements and living expenses that affect work-family conflicts. Moreover, applying psychological intervention to improve job satisfaction and ego-resilience of middle-aged women in the working environment will help reduce work-family conflicts.

Smart work is an alternative form to enable seamless business collaboration without time and space limitations using ICT. However, smart work implementation has not produced tangible achievements and sometimes has resulted in failure. This study examined users' resistance against smart work, which is regarded as one of the most important elements for the successful implementation of smart work. The study classified elements which cause users' resistance into the work's innovative characteristics and the user characteristics based on the model of innovation resistance. It also set the degree of freedom in spatial and temporal dimension as moderating factors. This empirical research results showed that low work efficiency, unfavorable evaluation methods, and high degree of satisfaction in the way of working affected smart work users' resistance. In addition, temporal freedom had a moderating effect on the relationship between users' characteristics and their resistance. On the contrary, spatial freedom affected the relationship between their works' innovative characteristics and their resistance. The study results suggest that organizations need to set up business processes and evaluation methods first to adopt Smart work successfully.
