In recent years, various studies have been carried out on various types of entrepreneurship and comparative activities according to policy efforts and support such as the activation of a bachelor's degree in the establishment of a university, and attention has been paid to the fact that the participation and the educational effect of the students may be different depending on the type. The purpose of this study is to investigate entrepreneurial motivation, entrepreneurship, and entrepreneurial intention in the case of experiential entrepreneurship class focusing on the theoretical-oriented general entrepreneurship class, And the effect of entrepreneurship on entrepreneurial intention. The data were collected and empirical analysis was conducted to compare the difference between the two groups. The results of this study are as follows: First, out of the motivation factors of entrepreneurs, entrepreneurship education, achievement desire, human network, self - esteem, etc. We can confirm that the motivation of entrepreneurs is recognized more greatly. Second, the entrepreneurship factor was not significantly different from the perception between experiential entrepreneurship lecture and theoretical entrepreneurship learner. Third, experiential entrepreneurship learner perceived more willingness to start business than theoretical entrepreneurship learner. Finally, among the entrepreneurship motivation factors, among the entrepreneurship education, achievement desire and entrepreneurship factor, the risk sensitivity affects the entrepreneurial will. This study suggests that the direction of entrepreneurial education focused on quantitative expansion and the creation of qualitative effects of entrepreneurship education are needed. In the future, it will provide policy implications for revitalizing experiential entrepreneurship education In addition, it can contribute to the diffusion of research on the effect of entrepreneurship education.

In this paper a heuristic method for identifying individual pipes in water pipe networks to determine specific sections of the pipes that need to be replaced due to deterioration. An appropriate minimum pipe length is determined by selecting the pipe length that has the greatest variance of the average cumulative break number slopes among the various pipe lengths used. As a result, the minimum pipe length for the case study water network is determined as 4 m and a total of 39 individual pipe IDs are obtained. The economically optimal replacement times of the individual pipe IDs are estimated by using the threshold break rate of an individual pipe ID and the pipe break trends models for which the General Pipe Break Prediction Model(Park and Loganathan, 2002) that can incorporate the linear, exponential, and in-between of the linear and exponetial failure trends and the ROCOFs based on the modified time scale(Park et al., 2007) are used. The maximum log-likelihoods of the log-linear ROCOF and Weibull ROCOF estimated for the break data of a pipe are compared and the ROCOF that has a greater likelihood is selected for the pipe of interest. The effects of the social costs of a pipe break on the optimal replacement time are also discussed.

The purpose of this study is to explore practical intervention strategies by identifying the relationships among digital informatization capacity, level of digital informatization accessability and life satisfaction of disabled people and to determine differences among these relationships depending on perceived level of social support networks. The participants were 1,639 disabled people from the 2017 digital information gap survey and the results, based on structural equation modeling and multi-group analysis, are as follows. First, digital informatization capacity has a positive influence on the level of digital informatization accessability(β=.65), and life satisfaction(β=.08). The level of digital informatization accessability also has positive influence on life satisfaction(β=.44). Second, the analysis result of the mediated effects of digital informatization accessability level between digital informatization capacity and life satisfaction was significant at a level (β=.29) even greater than the direct effect of digital informatization capacity on life satisfaction. Third, digital information capacity and digital informatization accessability have an influence on life satisfaction regardless of their perceived level of social support. The findings suggest that creating online environments where disabled people can enjoy leisure, culture, and social interaction with high accessibility and utility are as important as providing education for improving their digital informatization capacity.

Effects of addition level of sodium chloride (NaCl) on gel properties of surimi-like pork (SLP) were investigated. Porcine semimembranosus muscle was used to manufacture SIP contained 1, 2, 3 and 4% NaCl to measure moisture content, pH, color, gel strength, micro-structure and sensory evaluation. The pH and moisture content of SLP were decreased as increasing of NaCl level. However, the gel strength of SLP was increased with increasing of NaCl level. Values of yellowness and chroma were lower in SLP of 2% and 3% NaCl compared with those of 1% and 4% NaCl. Amorphus protein particles size in micro-structure of SLP was decreased and coagulated as increasing level of NaCl. SLP of 1% NaCl had a structure formed by aggregates of densely packed globular proteins and arranged in clusters, whereas a well-structured matrix with a highly interconnected network of strand was observed in SLP of 4% NaCl. Result suggested that the increasing gel strength with NaCl level might be due to lower moisture content and denser micro-structure of gel.

The purpose of this study was to investigate the effects of black foods (black rice and black garlic) and the ratio of black garlic on the quality of Sulgiddeok. Pasting properties as measured by a rapid visco analyzer (RVA) were lower for black rice flour than white rice flour. Colorimetric analysis revealed that L, a, b values were dependent on the type of rice. For texture profiles, texture was associated with RVA profiles. During storage, hardness of black rice Sulgiddeok increased to a lesser degree than that of control. After observation via scanning electron microscopy (SEM), black rice Sulgiddeok showed a honeycomb-like network structure. In sensory analysis, black rice Sulgiddeok showed a tendency to prefer the control. The addition of appropriate black garlic (BG1) helped to improve the quality. In accordance with the aforementioned results, decreased retrogradation related to black rice Sulgiddeok and black foods (black rice and black garlic) could result in quality products with high nutritional value.

Currently, highway design speed is determined by considering highway function, area type, and terrain type. Sometime it is pointed out that determining a reasonable design speed which is both efficient and safe is not an easy task and that Practicing engineers often select an unsuitable design speed on purpose, capitalizing on some ambiguous and discretionary expressions in describing the highway design speed. This undesirable Problem is arising mostly due to the fact, that the current geometric design standard fails to include rolling terrain type and can not reflect the whole characteristics of land use patterns adjacent to the design highway route. A recent research was Published considering this problem and it attempted to improve the highway design speed determining process. In this research Project, tn see the effects of this recently developed procedure, a new and reduced design speed was calculated based on the new Procedure and subsequently another highway design route was selected. The travel time. construction cost. and the expected degree of safety associated with the new route were assessed to be compared with the ones with the existing procedure. As a result. it was found that the new procedure was successful in reflecting the localities such as terrain type and area type into better determining highway design speed, eliminating much of highway engineers' discretion when applying engineering judgments. Also the new Procedure is keen to produce a more economical highway project. In other words, despite of producing reduced amount of user benefits accrued, in the new highway route, the construction cost has been cut significantly leading to higher values in B/C. NPV, and IRR. Also EMME-II output, which Provided the link assigned volumes, rendered only a slightly reduced Levels of Service along surrounding links in the study network. This reduction was believed to occur because of lower design speed and it had been expected from the beginning.

Since policies of each local government toward regional development have been focusing on only development of the individual applied items such as a character merchandise, co-regional brand, and developing a speciality for the region, the adverse effects of design have been came out. So we carried out this research to minimize the adverse effect of design and also we would like to give the opportunity of thinking of a new way to activate local economy, to create regional identity and to develop local resources by applying the Cl program which have bean used as the way of business improvement coping with the conceptional change of competitiveness with a comprehensive view. Therefore, for design to play an important role in regional development, as standing on the basis of regional development it is necessary to attain the various goals such as activating administrative organization, improving the administrative image, and making the local in go unique. And also it is necessary to develop the communicational strategy as an innovative and expressive program which can consider human network development as an regional resource. To carry out this communicational strategy effectively, in particular, it is not only inevitable to operate the strategic and comprehensive programs promoting the regional development according to the of 6 stages design develop cent program which consists of region's self-verification and self-recognition, self-determination, development of self-innovation, visibility to unify the regional images, creating the design system, and carrying out and verifying the program, but also it is necessary to apply regional development system which can change the regional basic plan, aiming at regional development, into unique regional trait that has an future image by improving the program with constant management and feedback through verifying the design program.
