This research attempted to analyze the measurement of users' recognition level which is based on the theoretical background of social capital created in public libraries. The path of structural model was set among the factors of social capital and their causal relationships were verified. The users' awareness of social capital created in public libraries is to prove the value of their existence and sustainability in the region. It was clear that social capital affected the various benefit and social impact for regional people and local community. Finally, the findings of this research will be positively expected to affect the assessment of public libraries.

The purpose of this study was to examine what caused bakery employees at tourist hotel to leave their job. It's basically meant to lay the foundation for increasing personnel management efficiency and reducing turnover rate, as an attempt to prevent workers from quiting their jobs would be a successful way to take advantage of human resources more efficiently. Both theoretical and experimental approaches were utilized to serve the purpose of this study. First, concerning salaries, their turnover intention was under the influence of whether they were properly paid or gained a sufficient living. Second, as for environmental factors, their turnover intention was affected by performance appraisal and interpersonal trust with colleagues. Third, regarding job-related factors, their turnover intention was impacted by whether their job was clearly defined, how much they were satisfied with their job and whether their posts were suitable. Forth, the change of job was subjected to the influence of the desire for job in another region, job in another company and another kind of job. And there should be a clear distinction between sales and other works, and they should carefully be treated so that they could find their job more satisfactory.

Social capital theory provides a robust framework for analyzing economic well being. The purpose of this study was to investigate the effects of social capital on the economic satisfaction of retirees in Korea. The data from the first wave of KLoSA(Korean Longitudinal Study of Aging) were used(n=1,628). SPSS 12.0 was used for descriptive statistics and multiple regression analysis. The major findings were as follows: First, after controlling for gender, age, region, housing tenure, and personal income, the social capital of the retirees, including cognitive social capital(trust and reciprocity) and structural social capital(emotional and economic familial support, and a well-developed social network), contributes to increases in their economic well-being. Second, the degree of effect social capital has on well-being varied by gender and age; the effect was also different according to gender, regardless of the person's age. These empirical results provide a basis for the institution of policies that help bolster economic wellbeing for retirees by creating conditions that increase social capital in this group.

In this paper, we would be searching for the complemental aspects in industrial relations of Korea compared with that of Japan. It is very reasonable that historical, geographical, and especially gene analysis data are almost identical, considering that the general evaluations to the motive of Japan's industry are $\ulcorner$the modernization of the tradition$\lrcorner$. Although it is reported Korea accomplished the high economic growth rate, the economic growth rate(efficiency) could not be continued. This reason looks like that Korean proper(eigen) traits(:Gene-ware) have been oppressed and concealed by social climate such as jealousy, stratagem and hatred, we can find one of this facts in the criminal and complaint numbers as social trust measurement. There are many cases that Korean industry was distorted by the superiority/inferiority relations, for examples, the loss of the native(eigen or proper) resources, a distorted introduction of the production method and the unfolding of the industry which be not related to the characteristics of region. In this reasons, Korean industry could not play the role of Human-ware function which activates Gene-ware or, Gene-Nascence. In this Human-ware aspects, Japanese characteristics, such as $\ulcorner$Getting the basic right$\lrcorner$ and $\ulcorner$Tendency to the origin$\lrcorner$, are to be useful in the Nascence of Gene-ware in Korean industry.

Existing methods for the registration of blurred images are efficient for the artificially blurred images or a planar registration, but not suitable for the naturally blurred images existing in the real image mosaic process. In this paper, we attempt to resolve this problem and propose a method for a distortion-free stitching of naturally blurred images for image mosaic. It adopts a multi-resolution and robust feature based inter-layer mosaic together. In each layer, Harris corner detector is chosen to effectively detect features and RANSAC is used to find reliable matches for further calibration as well as an initial homography as the initial motion of next layer. Simplex and subspace trust region methods are used consequently to estimate the stable focal length and rotation matrix through the transformation property of feature matches. In order to stitch multiple images together, an iterative registration strategy is also adopted to estimate the focal length of each image. Experimental results demonstrate the performance of the proposed method.

Globalized cities are currently showing changes due to autonomous driving (AD). It is also maximizing globalization connections in cities where autonomous mobility is as complex as AD. The purpose of this study is to reveal that cities that realize AD and mobility will grow into globalized cities. Several cities, including New York and Shanghai, have attempted and are in progress, but failed cities are increasing. Although the technology of AD and the trust of citizens are prioritized, the city that has built the city's infrastructure is expected to be a city that has succeeded in AD. This is because commercialized cities or AVs will become hubs for mobility globalization, excluding rapid climate change or AV companies, and empirical analysis has been conducted that if AVs fail in metropolitan New York due to urban complexity (population density), urban economy size (GRDP), patents, number of consumers, infrastructure public EV chargers, and road quality. It examines whether the realization of AD by region and country affects overall national innovation. As a result, even if AV succeeds in large cities such as New York, Seoul, which has a higher population density (complexity), has a negative meaning, and a more similar Tokyo has a positive meaning. It can be seen that regional research on AV should also be prioritized in large cities such as Shanghai. This means that in order for AV to be realized in each city, the construction of AI infrastructure data must be actively changed to establish globalization of cities for economic growth as autonomous mobility.

The present study examines the impact of value co-creation on satisfaction and intention to adopt of e-resources among users. Four components of the DART model have been adopted to describe value co-creation. These components are dialogue, access, risk-assessment, and transparency. Ph.D. scholars and faculty members from National Capital Region, India, were requested to respond on a five-point Likert scale. A total of 220 responses were collected with the help of a structured questionnaire from respondents of the top 50 business schools according to National Institute Ranking Framework. These responses have been analysed by means of structured equation modelling on Adanco 2.2 software. Findings of the study reported the insignificant impact of access and risk-assessment, and positive impact of dialogue and transparency on satisfaction. Further, satisfaction has been identified, creating significant impact on adoption of e-resources. Such findings reflect the real picture of customer experience with respect to their role in co-creation of e-resources. Respondents have conveyed their dissatisfaction with the co-creation process of e-resources, as companies do not provide all the information and access to their customers beforehand. Consequently, customers fail to make informed decisions and also find themselves unable to show trust in the service providers of e-resources.

The CUPID code was developed and is continuously updated in KAERI. Verification and validation (V&V) is mainly done for light water reactors (LWRs). This paper describes a benchmarking of the detailed mesh level compared with sub-channel level for application to pressurized heavy water reactors (PHWRs), even though component scale comparison for the PHWR moderator system was done once before. We completed a sub-channel level comparison between the CUPID code and the ASSERT code and a CUPID code analysis. Because the ASSERT code has already been validated with numerous experiments, benchmarking with the ASSERT code will offer us more trust on the CUPID code. The target channel has high power and thus high pressure deformation. The high power channel tends to have a high possibility of critical heat flux (CHF), because a high void fraction and quality in channel exit region appear. In this research, after determining the reference grid and T/H model, we compared the sub-channel level results of the CUPID code with those of the ASSERT code.

A low-energy dielectric loaded accelerator with a non-uniform, multi-segment structure is studied and optimized. So far, no analytical solution is provided for such structures. Also, due to the existing nonlinear behavior and a large number of geometric parameters, the problem of numerical optimizations is complex. For this reason, a method is presented to design and optimize such structures using the Genetic Algorithm (GA). Moreover, the GA output results are compared with Trust Region (TR) and Nelder-Mead Simplex (NMS) methods. Comparative results show that the GA is more efficient in achieving optimization goals and also has a higher speed than the two other methods. Finally, an optimized accelerating tube is integrated into a proper coupler. Then, the accelerator is simulated for full electromagnetic investigations using the CST suite of codes. This design leads to a structure with a power of about 80 kW in the X-band, which delivers electrons to the output energy in the range of 300-459 kV. The length and outer diameter of the accelerating tube obtained are 10 cm and 1 cm, respectively.
