  • Construction Management service has been consistently growing in both sales and diversified services. On the other hand the market has been solidified owing to monopoly of major companies and considerations of the services have not been sufficient so that construction management could not play a appropriate role of the construction industry. This research is to suggest the improvements of construction management delivery system based on the analysis of the current market. The method conducted was to analyze market survey, literature and statistical review, regulations, considerations and evaluation system. Through the analysis and research, the delivery system of construction management was proven rooms for improvements in regulation, consideration, and evaluation system. and this study presented those as fair as possible. It is hopefully expected that the expansion of CM market, impartial competition, and justifiable services are implemented in the construction industry.

  • The purpose of this study is to review domestic and foreign origin labeling system in order to implement origin labeling system in the perspective of protecting the interests of consumers, and to suggest governmental improvements by analyzing problems embedded in current labeling system. The results analysis show complexity of related legal system, lack of expertise at the stage of labeling, and inefficiency of crackdown authority. The improvement could be suggested in two ways: supporting plans for the ones who have duty of labeling and improvement plans in origin management system. As supporting plans, we suggest the need for an automatic origin determination system, appropriate education on origin stakeholders, and introduction of origin certification system. For improvement plans, there are unification of country of origin labeling related laws, utilization of FTA product specific rules, and QR code, expert confirmation system. Since the origin labeling issue has become important, proactive and quick responses must follow with thorough examination the effect of the origin labeling on consumer welfare.

  • PURPOSE: This study examined the effects of functional electrical stimulation (FES) on temporal-spatial gait and the activities of daily living in hemiplegic stroke patients. METHODS: The subjects were 29 hemiplegic stroke patients (57.7 ± 10.3). The patients walked at a self-controlled speed in four states: (1) walking without FES (non-FES), (2) walking with FES on the gluteus medius in the stance phase (GM), (3) walking with FES on the common peroneal nerve and tibialis anterior in the swing phase (PT), (4) walking with both GM and PT. A GAITRite system, Timed-Functional Movements battery, and Timed UP and Go test were used to measure the variables. RESULTS: Significant improvements were observed in all variables of the GM+PT, GM, and PT states compared to the non-FES state (p < .05). There were significant improvements in the GM+PT state compared to GM and PT states (p < .05). Moreover, significant improvements were noted in the single support time on the affected side, backward walking 10ft, and side stepping 10ft on the affected side of the GM state compared to the PT state (p < .05). There were significant improvements in the stride length on the affected side and side stepping 10ft on the unaffected side of the PT state compared to the GM state (p < .05). CONCLUSION: FES is effective in improving the temporal-spatial gait and activities of daily living in hemiplegic stroke patients.

  • Since 1995, the facility of class 1 and 2, classified by law had been subject to system of post maintenance management where periodic safety inspection and diagnosis to identify any problems and to take appropriate measures as a matter of urgency. Although the standards and systems had been revised many times for continuous improvement due to surrounding environmental factors, the technical factors and other factors for improvements, continuous researches and efforts are needed to ensure even higher effectiveness. Furthermore, the consciousness of the management body that executes and implements such improvements for facility management is most important. Therefore in this study, through such analysis, more realistic management consciousness review was performed. Also the direction for improvements is proposed, to carry out more effective facility safety management systems implementation.

  • The purpose of this study was to analyze the actual condition of the innovative sharing university project. To this end, a focus group interview was conducted by selecting officials participating in the innovative sharing university project as study participants. The collected data was analyzed using the content analysis method. The results of the study are as follows. First, in terms of the promotion system and operation dimension of project group, study participants presented difficulties and improvements in terms of the national promotion system and university-level project operation. Second, in terms of curriculum management dimension, study participants presented difficulties and improvements in content development and sharing, engagement support for professors and students participation, and securing and sharing educational infrastructure. Third, in terms of management of project performance indicators, study participants presented difficulties and improvements in managing core performance indicators, managing autonomy performance indicators, and sharing project performance. Based on these study results, suggestions for the use of research results were presented.

  • An implementation scheme and some improvements are proposed to adopt public-licensed operating system, Linux and de-facto world-wide network standard, TCP/IP into the field of behavior-based autonomous mobile robots. To demonstrate the needs of scheme and the improvement, an analysis is performed on a server/client communication problem with real time Linux previously proposed, and another analysis is also performed on interactions among TCP/IP communications and the performance of Linux system using them. Implementation of behavior-based control architecture on real time Linux is proposed firstly. Revised task-scheduling schemes are proposed that can enhance the performance of server/client communication among local tasks on a Linux platform. A new method of TCP/IP packet flow handling is proposed that prioritizes TCP/IP software interrupts with aperiodic server mechanism as well. To evaluate the implementation scheme and the proposed improvements, performance enhancements are shown through some simulations.

  • The targeted nuclease clustered, regularly interspaced short palindromic repeats/CRISPR-associated proteins (CRISPR/Cas) system has recently emerged as a prominent gene manipulation method. Because of its ease in programming targeted DNA/protein binding through RNA in a vast range of organisms, this prokaryotic defense system is a versatile tool with many applications in the research field as well as high potential in agricultural and clinical improvements. This review will present a brief history that led to its discovery and adaptation. We also present some of its restrictions, and modifications that have been performed to overcome such restrictions, focusing specifically on the most common CRISPR/Cas9 mediated non-homologous end joint repair.
