Osteoblast is one of cells related with osseointegration and many research have conducted the adhesion of osteoblast onto the surface of implant. In the osseointegration, biocompatibility of the implant and cell adhesion to the surface are important factors. The researches related to cell adhesion have a direction from micro-scaled surface roughness to nano-scaled surface roughness with advancing nanotechnology. A cell reacts and sense to stimuli from extracellular matrix (ECM) and topography of the ECM [1]. Thus, for better osseointegration, we should provide an environment similar to ECM. In this study, we synthesize TiO2 nanowires using hydrothermal reaction because TiO2 provides inertness to titanium on its surface and enables it used as an implant material for the orthopedic treatment such as fixation of the bone fracture [2]. Ti substrate is immersed into NaOH aqueous solution. The solution are heated at $140{\sim}200^{\circ}C$ for various time (10~720 minutes). After heat treatment, we take out the sample and immerse it into HCl aqueous solution for 1 hour. The acid treated sample is heated again at $500^{\circ}C$ for 3 hours [3]. Then, we culture osteoblast on the TiO2 nanowires. For investigating cell adhesion onto nanostructured surface, we conduct several tests such as MTT assay, ALP (Alkaline phosphatase) activity assay, measuring calcium expression, and so on. These preliminary results of the cell culture on the nanowires are foundation for investigating cell-material interaction especially with nanostructure interaction.

This article aims to analyze the issue of sexual shame and finding answers for how to solve the problem of unjust shame when victims have suffered shaming in a new direction. While existing philosophical arguments have focused on moderating the negative effects of shame by changing the victims' mind, this article tries to fathom the necessity of how to make offenders feel shame. For this, firstly, characteristics of sexual shame on self are described in brief. And then, the article reviews the problems and limitations of existing philosophical methods which have concentrated on changes of victims' thoughts in order to overcome or prevent the negative effects of unjust sexual shame. Next, considering the liberal political philosophy's argument that it is not appropriate that even offenders who committed wrongs should experience shame as there exists an excessive emphasis on the negative aspects of shame, the overlooked positive aspects of shame on fostering human nature, are analyzed. Finally, in the context of sexual shame, the article explores what sense offenders should feel shame and what justifies shaming them.

This research reviews the education welfare priority support project and analyzes its policy from the welfare-state perspective. This study evaluates the policy contents, overall procedures, and the changes in the perspectives of the project in accordance with the political power changes in the government, and illuminates future directions. For this, the research infers desirable typology of the welfare state, and analogizes the budget, the target population, key issues and delivery systems of the education welfare priority support project. Education welfare priority support project still remains to follow a selective and hierarchical business format, despite the legally stated initiatives, growing budget, and the expansion of the operation which has been governed by the policy makers. Particularly, the state of this project, and examine whether or not it has been distorted by the governmental emphasis on the educational outcomes and performance should continuously be examined as a future direction of the research. Finally, the study suggests several recommendations for the desirable anchorage of the project within the framework of being a prospective welfare state.

Purpose: Prior studies have sought to find antecedent to improve firm performance. However, research on compensation systems and employees' psychological mechanisms have been relatively limited. In this sense, this study has investigated the impact of compensation gap between TMT and employees on firm performance, and explored the factors that affect the above relationship. Specifically, this study analyzed the direct impact of compensation gap on firm performance. In addition, the process of compensation gap to firm performance is assumed to be significantly influenced by employees' recognized promotion system and satisfaction with TMT. Therefore, we examined moderating effects of both promotion probability and opportunity, and satisfaction with TMT on the relationship between compensation gap and firm performance. Methods: For empirical test, financial variables were collected from TS-2000 database, and moderating variables were collected form Job Planet for listed firms in Korea. We conducted hierarchical regression analysis to test hypotheses. Results: The findings of empirical analysis are as follows. First, compensation gap between TMT and employees had a positive effect on firm performance. Second, when promotion probability and opportunity was high, the effect of compensation gap on firm performance was strengthened. Third, when satisfaction with TMT was high, the positive effect of compensation gap on firm performance was also strengthened. Conclusion: Our findings have expanded prior research on human resource management and labor relation by identifying the positive role of compensation gap between TMT and employees on firm outcome. Moreover, our results also indicated that promotion probability and opportunity, and satisfaction with TMT, which has not been addressed well in previous studies, were important conditions enhancing the positive relationship between compensation gap and firm performance. Finally, this study suggest several theoretical and managerial implication with future research direction.

Purpose: The purpose of this study is to suggest the policy and scope of the concept of sports welfare and to present a systematic model enhancing sport welfare of the society. Research design, data, and methodology: In order to induce idea for welfare policy and conceptual sport welfare model, this study reviewed a literature discussing the functions and mechanism of sport in enhancing a sense of life quality and thus rebuilding welfare of community. Results: The study suggests these. First, sports welfare ensures the rights of sports of all citizens and has the main purpose of providing social services, creating environments against inequality, improving the quality of life and happiness for everyone to enjoy, and the range should be continued from the right to live, environments against inequality, to the improvement of life and happiness. Second, since the integrated perspective was first suggested, sports integration development will be researched as well as the direction of the development of policies of the integrated model. Basic research of indicator development will need to be proceeded to execute and evaluate the integrated model. Third, the improvement of treatment of sports welfare instructors is urgent. Namely, compared to sports-related budget and the enhancement of facilities, the poor environment of sports welfare instructors needs to be improved. Instead of only testing physical fitness and prescription, the business needs to be continued by connecting to the participants' continuous participation in sports. Conclusions: Whether sports welfare succeeds depends on the need for an active beneficiary, identification of demand, a beneficiary that can discover potential to join offline and online into one, the establishment of sports policies to promote competency development, and a direct progression is needed.

Experimental animation is an independent art animation and a visual art that is integrated with the spirit of experimentation. Norman McLaren pursues original beauty in each piece through scientific exploration of visual expression technology and experiment that transcends common sense with great creativity and sensitivity, and the aesthetic value of animation is very high as the master of experimental animation that has brought innovation of real image media today. Therefore, it is meaningful to analyze the experimental expressions of Norman McLaren, who expanded the field of experimental animation by challenging various techniques and carried out a ceaseless search for motion creation between each frame, and to study the expressions of movement he focused on. The most significant feature of his movement expression was analyzed as repetition of motion and repetition of metamorphosis. I hope that this derivation will be understood as experimental animation of experimental method which requires more specific type of inquiry than simple question about experimental method. Also, I hope that it will be meaningful as a preliminary study to deeply explore the possibility and direction of animation creation in university education.

With the low birth rate and the inner city decline, the number of small schools is expected to increase. In this trend, the Ministry of Education has consistently used the number of students as a standard for the merger and abolition of schools since 1982, but it seems that has generated a vicious circle of education in rural areas and also it did not reflect realistic requirements and changes in the times although it is efficiency of local education finances. With the number of students constantly decreasing, it has a high probability to make villages without schools in urban areas if decisions are made by the number of students. In this sense, it is suggested that regional contexts and socioeconomic environment should be taken into account rather than to conduct the merger and abolition of small schools with economic logic. It is necessary to change the direction of improving the quality of education through the operation of small schools for coexistence of schools and villages and a cultivating the manpower needed in the 21st century knowledge information society and the 4th industrial revolution era. Therefore, we tried to find tasks for expanding small schools of the local community and developing small schools suitable for future social change.

As digital media technology continues to evolve, media arts are being created using new technologies. Among them, interactive media provides new experience and interest to the audience in that the audience is completed only by participating in the works. The use of these characteristics as a marketing strategy has led to an increase in sales and a positive image of the company. Through this study, we analyze the case of interactive media contents and infer the usage plan and elements. In addition, we propose a prototype of interactive media contents that can be used as a strategic marketing element by exploring ways to utilize interactive media as a marketing element of the film industry. This suggests the development direction of interactive media that provides a continuous and new sense of immersion to the audience, and suggests subsequent research on effective use of the industry as well as movie marketing.

This study evaluates the social value orientation, well-being of the elderly and care needs of elderly that elderly care services are identified and seeks future service development directions through a desire survey. As of October 2019, 1,501 elderly living alone who used basic care services for the single elderly households for more than 3 months were sampled, and frequency analysis, technical statistical analysis, t-test, and variance analysis were conducted. The survey found that social value orientation averages 90.93, and the sense of well-being of the elderly is 71.29 points. As a result of the analysis of variance and post-hoc analysis, the well-being of the elderly was statistically significant in groups well aware of their social value orientation. In addition, key words such as "loneliness", "lonely Death", and "safety" were derived for concerns that may arise when the service is discontinued. Based on the results of this study, it could be used as basic data to explore the development direction of the new "elderly care services" and to establish a care system for senior citizens in preparation.
