Purpose: This study, using a pre-posttest design of non-equivalence comparative groups, was done to determine effects of KC (kangaroo care) on weight and SH (stress hormone) of premature infants. Method: Participants were 31 premature infants assigned to KC(14) or CG(control group)(17). Data were collected from June 2006 to February 2007. KC was given for 60 minutes at a time, Mon, Wed, and Fri for a 10 times. Body weight was measured at a fixed time daily and serum cortisol was examined as part of routine blood testing, frequent for premature infants. Results: The weight for infants in the KC group was higher than the control. The difference was significant between both the two groups, and the 2 measurement times(F=12.7, p=.001). SH(cortisol) in infants of KC group decreased than CG, but there was no valid difference from the statistical viewpoint. Conclusion: The result of the study suggest that KC contributes to weight increase in premature infants and also that KC is effective for SH reduction in spite of the lack of statistical validity. Therefore, our conclusion is that KC can be used as an independent nursing intervention for development and advance of premature infants.

Purpose: This study was performed fracture strength test by conducted change of abutment and coping shape for suggesting monolithic all ceramic crown which has thin thickness and superior strength of the occlusal surface. Methods: The specimens on the four kinds abutment was made according to thickness of occlusal surface and angle of axis surface. And All ceramic coping specimens of 6 different kinds was made by the CAD/CAM Method. Compression strength test using the UTM and the verification of compression-stress situation using the 3D finite element method were conducted under optimum conditions. Results: 516C specimen was showed the strongest compression-fracture strength, followed by 516FR, 516F45, specimens. Did not show significant differences between 516FR and 516F45. 516C of the universal testing machine the specimen's surface that are within the vertical load is small, finite element method of a uniformly distributed load, so the value received suggests otherwise. Conclusion: In conclusion, abutments of monolithic ziconia ceramic when having a same thickness of the occlusal, as the angle of occlusal edge is small, the stress is well dispersed and it can endure well in the fracture.

"Knowledge worker" is a term used to describe highly educated people whose role in the workforce involves the use of information and knowledge. Knowledge workers are key to the success of a great many organizations. Many Chinese companies find that the voluntary turnover rate among their knowledge workers is high. The purpose of this paper is to explore, from the perspective of knowledge workers and the characteristics peculiar to them, the factors that influence this high voluntary turnover rate. The models used in this paper, that will enable understanding of the characteristics of knowledge workers in China, are the Chinese Personality Assessment Inventory and the Five Factors Model. In the case of Huawei, analysis using these models leads to the conclusion that the main factors that influence the voluntary turnover of knowledge workers in China are: age; gender; degree of extraversion and how open the person is to new experiences; family orientation; and occupation. This study leads to the conclusion that the company should pay closer attention to three groups: female employees who put a high value on their families; employees from non-R&D departments; and younger employees who show a high degree of openness to new experiences.

Retrieval of scholarly articles about a specific research issue is a routine job of researchers to cross-validate the evidence about the issue. Two articles that focus on a research issue should share similar terms in their core contents, including their goals, backgrounds, and conclusions. In this paper, we present a technique CCSE ($\underline{C}ore$ $\underline{C}ontent$ $\underline{S}imilarity$ $\underline{E}stimation$) that, given an article a, recommends those articles that share similar core content terms with a. CCSE works on titles and abstracts of articles, which are publicly available. It estimates and integrates three kinds of similarity: goal similarity, background similarity, and conclusion similarity. Empirical evaluation shows that CCSE performs significantly better than several state-of-the-art techniques in recommending those biomedical articles that are judged (by domain experts) to be the ones whose core contents focus on the same research issues. CCSE works for those articles that present research background followed by main results and discussion, and hence it may be used to support the identification of the closely related evidence already published in these articles, even when only titles and abstracts of the articles are available.

As the competition of city design from various municipals recently, color guidelines are continuously established. But the contents of color guidelines are differing from one municipal to the other, It has doubts on its effectiveness. Thus, the objective of this researchis to investigate municipals' color guidelines in order to apprehend the characteristics and differences among each other. In order to do this, the research will collect color guidelines of 5 different cities and 2 different districts. Then, by organizing tables for different characteristics of contents, the research will attempt to identify the difference between municipals. The conclusion of such research is as follows. First, basic contents of color guidelines are composed with planning, proposing and managing stages. Furthermore its objective, target subject, detailed guidelines and exemplary cases were common. Second, the contents of color guidelines of municipals were vastly differing from each other in respect to the size of the cities or the objectives of its application. Third, color guideline contents of the city of Seoul, Sejong city, and Chung-ra district are composed rather reliably while that of the city of Inchun, and Sung-buk district were lacking considerably in terms of up-to-date survey of environment, color proposal, and managing policy in comparison to other municipals. In conclusion, there is a strong necessity for standardization of establishment or form of the color guidelines. Furthermore, measures for proper adjustment in respect to the size of a municipal or its purpose should be arranged adequately.

Background: Galeal or temporalis muscle flaps have been traditionally used to reconstruct skull base defects after tumor removal. Unfortunately, these flaps do not provide sufficient vascularized tissue for a dural seal in extensive defects. This study describes the successful coverage of large skull base defects using anterolateral thigh (ALT) free flaps. Methods: This retrospective study included five patients who underwent skull base surgery between June 2018 and June 2021. Reconstruction was performed using an ALT free flap to cover defects that included the intracranial space and extended to the frontal sinus and cribriform plate. Results: There were no major complications, such as ascending infections or cerebrospinal leakage. Postoperative magnetic resonance imaging showed that the flaps were well-maintained in all patients. Conclusion: Successful reconstruction was performed using ALT free flaps for large anterior skull base defects. In conclusion, the ALT free flap is an effective option for preventing communication between the nasal cavity and the intracranial space.

Purpose: The purpose of this study was to examine the corporate responsibility activities and investigate the effects of these activities on financial performance in public institutions. Methods: The collected data using annual performance evaluation for the year 2017-2019 were analyzed using multi-regression analysis. The corporate social responsibility activities for this study were divided into three dimensions such as social value, efficiency, and welfare. Results: The results of this study are as follows; first, public institutions with high evaluation in social value and welfare had a significant positive effect on financial performance factors such as ROA and ROS. Second, we find that there is a significant negative relation between social value activities and debt ratio. This result means that the higher social value activities, the lower debt ratio. It was also found that the activities for enhancing social value made statistically significant positive influence on BIS performance. Conclusion: These results can be interpreted that public institutions trying various social contribution activities does not necessarily bring negative results for financial performance. In conclusion, it means that socially responsible activities and ethical management in the desirable direction can be beneficial to both public institutions and the society to which they belong.
