China has gone through rapid economic growth due to transitional economies since 1978. In particular, Chinese transitional economies has led to fundamental changes in firms' activities under the socialist system. Nevertheless, Chinese firms have formed new industrial production organizations and spatial orders by sustaining personal networks based on existing traditional firm practice, which is called 'guanxi'. Therefore, the main purpose of this research is to identify the influence of personal networks, guanxi, on the business activities of Chinese firms by investigating the formation of guanxi mechanism. The main characteristics of guanxi represented in inter-firm relations are as follows. First, guanxi has played a role in facilitating inter-firm relations and business activities, because it has an inter-debt relations based on inter-reciprocal relations between firms. Second, Chinese firms has depended on posteriori guanxi rather than inherent guanxi by the internalization of personal networks through 'guanxi communicators'.Third, guanxi between firms and local government in extra-firm relations has been established to minimize risks from unstable legal regulations.

The summarized analysis result of this research is as follows. First, regarding the difference of preceding variable and dependent variable, statistically considerable difference did not appear between self determination and personal relations in educational background and between groups of self determination in hotel type, and statistically considerable difference appeared among other groups. Second, regression analysis result between empowerment and job satisfaction turned out that statistically considerable influence is exerted in the order of personal relations ability, influence power, role performance ability and self-decision nature. Third, regression analysis result between empowerment and job devotion turned out that statistically considerable influence is exerted in the order of personal relations ability, role performance ability and influence power. Fourth, regression analysis result between empowerment and organization devotion turned out that statistically considerable result is exerted in the order of influence power and personal relations ability. Fifth, it turned out that statistically relative high correlation existed among correlation of empowerment and result variable such as job satisfaction, job devotion and organization devotion. The above-mentioned matters considered, this research proposes following points. This research examines the effect of empowerment on job satisfaction and organizational commitment of culinary staff in the hotel. the effect of the variable of empowerment on result variable shows that role performance ability, influence power and personal relations ability are important variables. Therefore, to improve the role performance ability of members of kitchen, it is essential for each individual to improve their ability and to have confidence at the time of business performance. So, this research implies that consistent and systematic training is necessary for increasing the ability and confidence. In order to improve influence power, it is necessary for members of an organization to have strong faith that their jobs determine the success of the company, and to increase the sense of self-control by letting them have the right of self determination, so that all members may have strong desire to transact business. This research implies that in order to improve personal relations ability, it is necessary for members of an organization to discover the best method of decision-making and solve problems through members' developing mutual action, and for managers to take personal characteristics into account so that members may have belief and confidence in their job and realize the value of their job. In conclusion, the person in charge of personnel affairs and the manager in charge of kitchen need to realize the importance of empowerment and especially have an much interest in all parts including self determination, influence power and role performance ability and personal relations ability etc.

'The Three Bonds And The Morals in Human Relations' was published in Joseon Dynasty period in 1434, relatively early days of comic history in the world. The gaps between comics frames have symbolic meaning as comics frames have in the area of symbols of comics. After comics frames appeared, it was likely that the advent of the gaps between frames had its own value in the aspect of comics history. Historical backgrounds of domestic comics would be built on firm base led by studying on the symbolic meaning of the gaps between comics frames. Two forms of the gaps between frames were shown in 'The Three Bonds And The Morals in Human Relations.' The first form is the gap between cloud frames. The second is the gap between cloud frame and background frame. Although a little difference is found in the shape and display, two forms of the gaps between frames in 'The Three Bonds And The Morals in Human Relations' have a similarity to modern comics. This study is to demonstrate valid background for the domestic history of comics by means of analyzing the shapes of the gap between comics frames in 'The Three Bonds And The Morals in Human Relations.' The objective of this study is to prove the meaning of the shapes of the gaps between comics frames 'The Three Bonds And The Morals in Human Relations', focusing the gaps between frames among symbols of comics.

The purpose of this study is to examine factors influencing social relations in elderly people participating in the Senior Employment Project and explore ways to improve their life quality by promoting the enhancing social relations in old age based on that. To attain the study goal, this researcher conducted hierarchical multiple regression analysis on 272 elderly persons having experience to participate a senior employment project selected through random sampling. According to the findings, elderly people's internal factors, self-esteem and external factor, job satisfaction, influence social relations in elderly people participating in the Senior Employment Project significantly. In other words, if elderly people participating in the Senior Employment Project have higher self-esteem, and job satisfaction, their social relations are better. Based on the results, this author provides political suggestions as follows: first, it is needed to develop policies and programs that can enhance elderly people's self-esteem. Second, it is necessary to acknowledge their worker's status, diversify business types and areas for them, and improve their labor conditions so that elderly people can show higher job satisfaction. Third, it is needed to develop both official and non-official support systems and build networks to form new social relations.

This study was conducted by surveying users' perception about the public libraries' current public relations, which can contribute to developing the most appropriate public relations strategies for persons with disabilities(PWDs). This study concluded, first, PWDs' experience with the PR of the library services was a very low 32.4%. Intellectual disabilities, especially, were reported to have no experience in public relations. Second, the library public relations media which PWDs utilized the most were the Internet, library bulletin boards, banners, ARS services, and podcasting, in that order. However, satisfaction with promotions appeared below average(3 points or less). On the other hand, interest in public relations media was very high. Third, it appeared that library users with disabilities most frequently use the websites of their school library, the National Library of Korea, and public libraries in that order. However, the usage rate of services and users' satisfaction with them were very low. Finally, a high demand for facilities with accessibility to PWD users emerged as a result of this study. Therefore, this study recommends greater accessibility, convenience, and ease of facility use for persons with disabilities.

The purpose of this study was to investigate the influence of professional self-concept and interpersonal relations on nursing competence of clinical nurses. This study was conducted as a descriptive cross sectional survey with 182 nurses who work at a tertiary hospital which has over 1,000 beds, located in Gyeounggi - do. The data was collected from October 11th, 2016 to October 28th, 2016. The main findings of this study were as follows. The mean score for professional self-concept was $2.65{\pm}0.29$ points in the range of 1 point to 4 points. And interpersonal relations was an average of $3.55{\pm}0.35$ points in the range of 1 point to 5 points. Nursing competence was an average of $2.65{\pm}0.39$ points in the range of 1 point to 4 points. Professional self-concept and interpersonal relations were positively correlated with nursing competence. Nursing competence was differed from clinical career(F=10.518, p<.001), working unit(F=4.139, p=.018), educational background(F=6.542, p=.002), and satisfaction on nursing(F=6.326, p<.001). The regression model with clinical career, working unit, educational background, satisfaction on nursing, 3 sub domain of professional self-concept(professional practice, satisfaction, communication), and interpersonal relation was statistically significant (F=31.94, p<.001). And this model could explain 51.5% of nursing competency(Adj R2=.515). Especially, professional practice(${\beta}=.532$, p<.001) of professional self-concept, interpersonal relations(${\beta}=.223$, p<.001), clinical career(${\beta}=.169$, p<.001), working unit: ICU (${\beta}=.169$, p<.05) were identified the factors influencing on nursing competence. Therefore, improving clinical nurses' nursing competence can be achieved with broad approach that includes improvements in professional self-concept and interpersonal relations. And also, working unit, and clinical career should be considered to develop the actual program for nursing competence, too.
