The purpose of this study was to conduct a dynamic analysis of married women's return to the workforce following first childbirth. We have based our investigation on the data compiled by the KLIPS, where the workforce performance is the focal point of it's research, and by these materials, this study has analyzed the aspects of the factors that decide post-childbirth return to the workforce. We have applied the Cox Regression Hazard Model, where corroborative evidence are statistically applied. The following are the conclusions that were derived from this research: First, according to the study, academic background is a vital factor in reducing the gap and time of women's return to the workforce. Second, whether having active child-care after giving birth or not doubles the chances of women returning to the workforce. Third, if the pre-birth employment form was a wage-work and the rate of returning to the workforce was lower than the non-wage, relatively speaking, this reflects that the non-wage form of work, which provides a better possibility to return to the workforce after giving birth, could be another way to prevent women's career discontinuation.

In the past, technology commercialization was implemented in a narrow sense, such as technology transfer or start-up support. It has been pointed out that lack of entrepreneurial experience, failure in technology development, and insecure markets lead to failure of technology commercialization. The project supporting direct commercialization of technologies owned by academic and research institutes conjoins public funds and operating power of large enterprises to introduce a new technology commercialization model that combines commercialization technology with capital, market, and government policies. And pain points for direct commercializing technology was derived. Through research and analysis, a gap was found between the demand factors and the capability of the actors performing the technology commercialization, and it showed a significant correlation with the paint points. In consequence, measures were drawn to improve support policies to enhance the efficiency of commercialization of technologies held by universities and research institutes.

The importance of Industrial Security is continuously growing along with the rapid development of convergence technologies. Accordingly, it is expected for the gap between the supply and demand of industrial security professional personnel to grow every year. In order to reduce the supply and demand of industrial security, it is important to not only train professional qualifications but at the same time, secure a professional qualification acquisitor. In this regard, South Korea has introduced the Industrial Security Expert qualification as a non-governmental qualifications ince 2010. From 2017, promoted as nation-certified qualification and has supported activities as expert in industrials ecurity field. However, it is reality that Industrial Security Expert qualification has not yet to be recognized as professional qualification in the field of industry, have low rate of utilization as academic research is also shown the sign of stagnation. Based on these background, this research set goal in deducing a activation method for industrial security professional qualification concentrating on Industrial Security Expert qualification. The analysis on operation condition of Industrial Security Expert qualification and related precedent research was conducted and raised four types of activation method, which are organizational aspect, certification system improvement and operation aspect, certification acquisitors' utilization aspect and professionalism enhancement aspect.

The thickness of adsorbed molecular layers is the most critical factor in studying thin-film lubrication, and it is the most essential parameter that distinguishes thin-film from thick-film lubrication analysis. The thin film between the shaft and bearing surface within a very narrow gap was considered. The general Reynolds equation has been derived for calculating thin-film lubrication parameters affecting the performance of the circular journal bearing. Investigation of the load-carrying capacity and pressure distribution for the journal bearing considering the adsorbed layer thickness has been carried out. A Reynolds equation appropriate for the journal bearing is used in this paper for the analysis, and it is discussed using the finite difference method of the central difference scheme. The parameters, such as eccentricity and attitude angle, are used for discussing the load-carrying capacity of the journal bearing. The results reported in this paper should be applied to analysis of the journal bearing with different lubrication factors. The steady-state analysis of the journal bearing is conducted using the Reynolds model under thin-film lubrication conditions. For a journal bearing, several parameters, such as a pressure, load capacity, and pressure components of the bearing can be obtained, and these results can be stored in a sequential data file for later analysis. Finally, their distribution can be displayed and analyzed easily by using the MATLAB GUI technique. The load-carrying capability of the journal bearing is observed for the specified operating conditions. This work could be helpful for the understanding and research of the mechanism of thin-film lubrication.

The aim of this document is to evaluate the effect of bite balance on physical fitness and motor capacity to determine the importance of the occlusal stability as a possible action mechanism of occlusal appliance including mouthguards on physical performances. We all remember that day when the prominent athlete was in the news wearing a mouthguard to improve human athletic performance. I once had investigated the determinants of athletic performance in all sorts of sports. Most of the studies had overinterpretation of results and lack of evidence to support the information. However, I discovered great expectations for new possibility in this field and settled for a more academic approach to this intriguing subject. The followings are some examples of the subject 1. Archers who wore occlusal appliances to increase the vertical dimension of occlusion by 2~3mm increased their ability to focus and to maintain good sense of balance. Their accuracy rate has been improved. The appliance was made of acrylic resin (a type of plastic). 2. Canoe players who wore occlusal appliances to increase the vertical dimension of occlusion by 5mm surpassed longtime competitor and won the race with 10 seconds gap. 3. A cycle rider who wore an occlusal appliance to treat his malocclusion surpassed his old record from 10.8 seconds to 10.3 seconds. His muscle reflexes (anaerobic exercise) and endurance (aerobic exercise) has been enhanced. 4. Occlusal appliances had a good effect on athletic performance in most sports such as swimming, diving, and weightlifting. As for the clenching on dentition, people clench their teeth when they push their physical and mental limits during sports activities. Clenching can be induced by physical exertion when maximum muscle strength is retained and this is similarly found in different types of exercises. In addition, restraint of respiratory function is observed. Therefore, creating a occlusal balance with occlusal appliance or mouthguard promoted a favorable influence when an athlete clenches.

Problem-based learning has been considered as one of the effective educational methods in engineering education. However, in so far as professors who require practical insights in PBL and experiences of developing actual problems by subject, in particular, thorough understanding from experiences of PBL process as well as problem-development has not been sufficiently provided. The purpose of this paper is to present strategies focusing on problem design for PBL on engineering education. In order to do this, a literature review and a qualitative case study were performed. Especially, the study intended to identify differences and gap between professors' problems-development process and its output and those of authentic PBL. Professors were found that their PBL problems had lack of authenticity, consideration on experiences of students, and realistic thinking process. Professors in PBL had difficulty to link theory into real situation. In consequence, in designing a problem, we consider the followings; first, the problem should be designed based on real design process and its output. Second, the problem should be designed and implemented in all academic years for developing student's systematic and skillful thinking process. In conclusion, more supports are needed for engineering professors to extend their experiences of designing and developing actual problems that present real experience.

The cooperation between universities and industries is already one of the most important factors driving the national economy in the knowledge-based society of the 21st century represented by the Fourth Industrial Revolution. The Korean government has also been carrying out legal and institutional re-adjustments to promote industrial-university cooperation in line with demands for such changes in the times. However, despite this industry-academic cooperation system, there is still a significant mismatch between industrial demand and the university's workforce development system. By the way, there is a Cooperative Education(CO-OP) in Canada and the United States. It's an innovative link between the university and the industry. The reason is that the CO-OP program not only allows students to gain experience with their majors in the industrial field, but also plays a positive role in improving their specialty expertise. In particular, field information, ideas, and job insights that students acquire through CO-OP also serve as motivation for starting a business beyond employment after graduation. Furthermore, CO-OP experience is an important opportunity for future researchers to come up with commercialized research results that are not separated from the field sites The purpose of this study is to overcome the gap between industrial demand and the college manpower training system, and develop a Korean-style coaching program model as a growth engine for creative talent-building policies, represented by 'creation of start-ups and new industry.' In addition, this study suggested measures that can be applied in real universities. In addition, the study also highlighted that the introduction of CO-OP programs with field practices in Korea could also boost start-ups. Based on the Korean CO-OP program model, the curricula applicable to domestic universities consisted of two types : general and research-oriented university types.

The main objective of this research aims at analyzing efficiency of government financial transfers(GFTs) to the Korean fisheries sector, using the Linear Structural Relations model(i.e., LISERL model) and the field survey data. Most policies of GFTs tend to be implemented to protect industries with weak competitive advantages such as infant and/or primary industries. Specific policy instruments include income transfers, government loans with lower interest rates, taxes and the like. Fishing activities are made at a highly changeable natural environment of the ocean with a great amount of risk and uncertainty. Fishing households make their livelihood under the small-scale fisheries. Such fisheries and fishing households have also a relatively weak market power. Because of these fisheries characteristics most coastal states have adopted a variety of government support programs. However, despite such a huge government support, during the past several decades the world fishing communities have seen a tendency of continuous fishereis resource overexploitation. For this resason there have been hot debates over the government support policies for fisheries through OECD, FAO, WTO, and UNEP. In general, policy evaluations tend to be made on the basis of benefit-cost(B/C) analysis. However, the B/C analysis may produce results quite different from real ones primarily due to many unmeasurable effects. Thus, the authors composed simple questionaires and let fishermen, government officials and academic people answer the questions. The survery was made in several ways such as post-mail and personal/group interviews. In recent years, for analysis of policy performances and effectiveness, the LISREL model has often been used, which consists of structural and measurement eqquations. This model has a good advantage of transforming unobservable variables to observable ones so that it helps construct endogenous cause and effect relationships among relevant variables. The evaluation was done from the two aspects: policy results and policy effectiveness. The policy result evaluation showed that there is a need for improvement for policy problem perception and decision-making process, while the policy effect evaluation suggested that the policy goals were successfully achieved and social justice was improved from the perspective of the entire society as well. However, the research results showed that the GFT policies rendered little contrubtion to narrowing down the gap between GFT beneficiaries and non-beneficiaries incomes.

Global electronic commerce, driven by the development of the Internet and computer, premises to be an important engine for growth for the world economy in the 21st century. Electronic commerce offers considerable new opportunities for businesses and citizens in all regions of the world by enhancing productivity across all sectors 6f our economies and encouraging trade in both goods and services. Specially in relation to contract, electronic commerce requires a coherent, coordinated approach internationally on key issues such as a validity, a legality, consumer protection. In order to ensure the stable growth of electronic commerce in Korea, the government needs to construct a predictable legal and commercial environment, suitable to the situation in Korea, for business conduct on the Internet and other electronic method. Electronic commerce, which breaks down national boundaries and widens the gap between the place where services are performed and the place where they are consumed, requires a new paradigm when making an agreement between contracting parties.

The present study aimed to understand high school students' environmental literacy for water and their attitudes toward environment. This study was conducted during the spring of the 2010 academic year with the participation of 123 students from a public international high school located in Seoul. The Environmental Science Literacy for Water test and the Revised New Ecological Paradigm scale were administered, and the data were analyzed by descriptive statistics and content analysis. The high school students in this study put strong emphasis on encouraging others to conserve water resources. This belief, however, was not aligned with self-recognition of their own roles in water supply shortages and other problematic water-use behavior. They also had difficulties in understanding the invisible part of matter transformations in water systems. Nevertheless, they showed favorable attitudes toward environmental conservation. In conclusion, the researchers suggest recognizing our own water problems and narrowing the gap between environmental and scientific knowledge of water and actual attitudes about the environment through curricular incorporation of interdisciplinary environmental science literacy into school science.
