The advancement of information technologies including the Internet has affected the way of social information processing as well as brought about the paradigm shift to the information society. Accordingly, it is very important to study the process of social information processing over the digital media through which social information is generated, distributed, and led to social consensus. In this study, we analyze the mechanism of social information processing, identify a process model of social consensus and institutionalization of the results, and finally propose a set of information processing characteristics on the internet media. We deploy the ethnographic approach to analyze the meaning of group behavior in the context of society to analyze two major events which happened in Korean society. The formation process of social consensus is found to consist of 5 steps: suggestion of social issues, selective reflection on public opinion, acceptance of the issues and diffusion, social consensus, and institutionalization and feedback. The key characteristics of information processing in the Internet is grouped into proactive response to an event, the changes in the role of opinion leader, the flexibility of proposal and analysis, greater scalability, relevance to consensus making, institutionalization and interaction. This study contributes to the literature by proposing a process model of social information processing which can be used as the basis for analyzing the social consensus making process from the social network perspective. In addition, this study suggests a new perspective where the utility of the Internet media can be understood from the social information processing so that other disciplines including politics, communications, and management can improve the decision making performance in utilizing the Internet media.

Recently, UCC, which stands for User Created Content, has emerged in various media industries including Internet. However, there exists little research regarding interaction to overcome the drawback of UCC, one way superficial form. In particular, little research has been done on the creation and effect of experiential UCC type. In the existing research, the interactive feature shows to bring the effectiveness in the field of education or promotion. So, in this study, we examine the problem of provider-centered UCC and to solve this problem, we propose a new experiential UCC form with interactive functionality by adapting the product test between UCCs. From the results of the analysis on the effectiveness of UCC after users experience the proposed UCC related to water industry, watching the interactive UCC represented the values of the higher levels in the aspect of recognition change than watching the existing UCCs. Also, the outcome showed that if this interactive UCC invigorates, UCC application will be very useful in eduction, industry, and promotion. From the analysis of the question instrument on whether an interactive UCC would be helpful or not, the positive response ratios was 84% in promotion, 70% in education, and 52% in industry, respectively.

The water extract of Omija-tang(OMJT) has been traditionally used for treatment of ischemic heart and brain damage in oriental medicine. However, little is known about the mechanism by which the water extract of OMJT protects cells from such damage. Therefore, this study was conducted to investigate the protective mechanisms of OMJT on $H_2O_2$-induced toxicity in H9c2 cardiomyoblast cells. Treatment of $H_2O_2$ markedly induced death of H9c2 cardiomyoblast cells in a dose-dependent manner. The characteristics of $H_2O_2$-induced death of H9c2 showed apparent apoptotic features, such as DNA fragmentation. However, OMJT significantly reduced both $H_2O_2$-induced cell death and chromatin fragmentation. The decrease of Bcl-XL expression by $H_2O_2$ was inhibited by OMJT. In addition, the increase of Bcl-XS and Bax expression were also inhibited by OMJT. In particular, Fas expression, which is generally recognized as cell death inducing signal by Fas/FasL interaction, was markedly increased by $H_2O_2$ in a time-dependent manner, whereas this increase was completely prevented by OMJT. The combined treatment of OMJT and $H_2O_2$ in H9c2 cells also reduced activation of caspase-9 and caspase-3 like protease. Taken together, this study indicates that the protective effects of the water extract of OMJT against oxidative damage may be mediated by the modulation of BcI-XL/S and Bax expression by way of the regulation of mitochondrial membrane potential and caspase cascades.

In current web-based systems, it is generally recognized that one way flow of information from providers to users can cause the static problem of document structure. Therefore, information update frequency and interaction between providers and users are quiet slow. Monopolized information can obstruct the free user's access and heterogeneous format and different protocols also make users difficult to retrieve and to collect information. To resolve these problems, in this study, we introduce the Web 2.0 to move toward the user's participation and share based on the social network and the OAI protocol to improve the free access and the interoperability on bibliographic information for Life Science and then design the bibliographic information network for life science. This network has four main functions such as: 1) Open Repository function that can make up user community for sharing and data exchange. Data such as article, seminar material, research note and research report are considered in design. 2) Open Collection function that can collect and store the metadata on distributed bibliographic information networks, 3) Open Access function that can manage the metadata in the open access environment, and 4) Administration function that can monitor the user activity and statistics and can inspect the registered data.

Rapidly changing healthcare environment and professional nursing practice need a strategy for the organizational development and goal attainment. An understanding of organizational culture could help managers enhance or expend their management strategy, thus increasing the probability of their success in the organization. On the other hand. organizational culture is an abstract concept and can show several views between sciences applying it. Therefore. organizational culture can be described to different ways with roots in each other discipline. Thus. it is necessary to define the concept of organizational culture in nursing perspective. This article reports a study conducted to analyze the concept of Nursing Service Organizational Culture. This study is performed by the guideline of Walker and Avant for concept analysis : selecting a concept. detering aim of analysis, identifying all use of concept. defining attributes. constructing model. contrary, borderline. related cases. identifying antecedents and consequences. According to the results of this study. the following definition attributes of Nursing Service Organizational Culture was suggested. We could define that nursing service organizational culture is the pattern of basic assumption and common belief that shared by the subordinates of nursing service. So, it provides a shared identity for all employees. Attributes of Nursing Service Organizational Culture were defined as (1) it is performed by the result of the interaction through formal. informal communication among nursing service organizational subordinations. (2) it has been performed unconsciously and reacts without ever thinking about the behavior. (3) it makes a unique pattern of behaviors to each nursing organization. which is different from other groups. (4) it has a broad and subtle forces to its subordinates. (5) it provides subordinates with the way of thought and behavior. (6) it influences on the output. stability. and de velopment of nursing service.

The globalization of services is closely related to other economic problems facing the world today. These are: 1) the globalization of economic activities, 2) the servicization of economic activities. The world economy is now move interconnected than at any time in its history. Investment decisions, production processes, labor market regulations and even environmental legislation made by one country or company affect other economies, other companies and the lives of individuals. In fact, it is nearly impossible to think of a country that is not connected to the world economy in some form or another and it is no exaggeration to state that globalization is already an unassailable fact. The fabric of our economy and the way we do business are changing. This change is the transformation from a marketplace on goods to one focused on services. That is to say, we live and work in a service-centered, service-sensitive economy. As a result of the globalization an servicization of economic activities, services require the globalization, and services are increasing their international trade, foreign investment, agreements, alliances, mergers and collaboration networks. It is quite obvious that services are affected by globalization ; but raising the question by how much leads us to the paradox of service globalization, services represent 70% of the most advances economies but only account for less than 25% of international trade and almost half of direct investment; mergers and takeovers. These figures create a paradox that can be explained by two reasons. First; the natural(the service relationship) and artificial difficulties(barriers to trade) faced by the service sector that inhibits globalization. Second, the non-inclusion in official statistics of the share of internationalized goods that are due to services, for example intra-firm trade or the service value incorporated into exported goods. If these were taken into account the service trade figures would be extremely different. The first explanation can be subdivided into a number of elements. The OECD identifies six reasons:services cannot be stored; client-supplies interaction requires local presence; most service firms are SEMs; products are highly differentiated; cultural differences are especially important in this field; and, finally, trade barriers and restrictions on local operations exist. However, despite all of this, globalization produces clear advantages to suppliers. Therefore, the objective of this study is to explore the main forms of service globalization and differences between that of goods, and is to identify distinctive aspects of service globalization within the framework of the global economy.

The purpose of the present study is to explore the process of teacher change as elementary school teachers participated in a community focused on improving mathematics teaching. To do so, a professional community lot improving instructional practice consisted of a group of voluntary elementary school teachers. The professional community provides participating teachers with great opportunities to share their understanding of practical knowledge related to mathematics teaching and learning and change mathematical beliefs as well as to learn pedagogical content knowledge. This study approached to teacher professionality in terms of mathematical beliefs and teaching practice. The change of teaching practice was measured coherently both with a questionnaire and with a mathematics teaching standard developed for this study. The findings of this study point out that techers' beliefs about how students learn mathematics have chantged. This study also indicated that after participating in the professional community focused on improving mathematics teaching, teachers' mathematical teaching is changed toward the more students' oriented way. Especially, it is observed that the meaningful change in participating teachers' teaching practice took place with respect to the role of teachers, students' interaction, mathematical tasks, and problem solving. Finally, this study implies that teachers can have an opportunity to change their beliefs and deepen their professionality about elementary mathematics teaching and learning through participating in the community of practice, through which participating teachers can share their practical knowledge and their understandings about teaching and learning of elementary mathematics.

1. Objectives: Leptin is ob-gene originated hormone that is concerned with energy metabolism, obesity and asthma which features are supposed to related with Sasangin's 4 viscera physiological theory of Sasang constitutional medicine(SCM). This study aims to investigate whether serum leptin concentration is associated with Sasangin. 2. Methods: Two Way ANOVA analysis was used on the constitution and serum leptin concentration corresponding with BMI among 1054 cases drawn from the Constitutional Information Bank, which was a database with clinically confirmed constitution cases collected from 21 oriental medical institutes in Korea starting from November 2007 to May 2009. The measurement of serum leptin concentration is implemented through radioimmunoassay by request to SCL. 3. Results: Male subjects showed notable difference(p=0.033) in the comparison between constitution and serum leptin concentration corresponding to BMI levels. Tae-eumins showed the highest serum leptin concentration levels in the normal and overweight groups, followed by Soyangin and Soeumin. As the groups changed from overweight to obese, there was an interaction phenomenon in the order of serum leptin concentration levels(p=0.040). As a result, Soeumins showed the highest serum leptin concentration levels and Tae-eumins and Soyangins followed in place. Female subjects did not show statistically notable differences in comparison between constitution and serum leptin concentration corresponding to BMI levels(p=0.239). Serum leptin concentration levels among overweight and obese groups, resulted in the order of Soeumins, Tae-eumins, and Soyangins. But in the as groups changed from overweight to normal the order resulted in Tae-eumin, Soyangin, and Soeumin(p=0.660). 4. Conclusion: Due to a number of limitations in this study, the examination of the relation between constitution and leptin, a main hormone responsible for the digestion, appetite, and energy metabolism, resulted to be uncertain. But statistically notable differences were confirmed in male Tae-eumins with the consideration of BMI. Further examination of the relation between constitution and leptin is necessary through prospective studies with the restriction of confusion variables in the future.

Purpose : This study was conducted to investigate the extent to which the professional self concept between the psychiatric mental health nurse practitioner (PMHNP) and general nurse in psychiatric ward was comparable. The results were expected to provide basic data for developing the construct of professional self concept and making awareness of the importance of the program increasing professional self concept. Method : The subjects of this study were 227 PMHNP and 436 general nurse in psychiatric ward. The instruments used for this study were PSCNI by Arthur (1990), PSI by Heppner and Peterson(1982) and the index of work satisfaction by Slavitt et al.(1978). With the aid of the SAS, t-test. two-way ANOVA and stepwise multiple regression were conducted. Result : 1. The average item score of PSCNI of PMHNP was $2.82\pm0.27$. and that of general nurse was $2.66\pm0.27$. Statistically significant difference between two groups was found(p=0.0000) 2. There was statistically significant difference between two groups in the score of professional practice(p=0.0000), satisfaction(p=0.0024), leadersbip(p=0.0000) , flexibility(p=0.0000) and skill (p=0.0000). 3. Statistically significant differences between the two groups were observed in terms of age(p=0.0003), marital status(p=0.0001). education(p=0.0005), religion(p=-.0144), motive (P=-.0001), length of service as a nurse(p=0.0121), the length of service in psychiatric unit(p=0.0143). However there were no significant interaction effect with group and age, marital state. education, religion, motive, length of service as a nurse, length of service in psychiatric unit. 4. Job satisfaction (JS) and problem solving inventory score(PS) were found to be the highest factor predicting the professional self concept between the PMHNP and general nurse. JS and PS accounted for $43.4\%$ in the professional self concept of PMHNP, whereas PS, JS, age and religion accounted for $53\%$ in the professional self concept of general nurse in psychiatric ward. In conclusion, this study suggested that we need to develop programs and polices to increase the professional self concept of nurse, particularly of psychiatric mental health nurse practitioners.

This study was carried out to compare the muscle activities of the shoulder stabilizers between persons with and without winging scapular during push-up plus exercise (adds the scapular protraction to the general push-up exercise). For this study, eleven males with winging scapular and eleven healthy males were recruited. Surface electromyographic (EMG) activity was recorded from the serratus anterior, upper trapezius, lower trapezius, infraspinatus, and pectoralis major while the subjects performed the push-up plus. Each push-up plus was subdivided into three phases according to the elbow position which was measured using the 3-D motion analysis system: elbow flexion (EF), elbow extension (EE), and shoulder protraction phases (SP). Two-way repeated measure ANOVA (phase ${\times}$ group) were used for statistical analysis. There was significant phase by group interaction only on the EMG composition ratio of the serratus anterior (p>.05). The EMG composition ratio of the serratus anterior was significantly higher in SP than in either EF or EE however, it was not different between winging scapular and normal groups. For both groups, the EMG composition ratio of upper trapezius, lower trapezius, and pectoralis major was significantly different across the phases of push-up plus, but the infraspinatus EMG composition ratio was not. For both groups, in EF and EE phases, the EMG composition ratio of both pectoralis major and serratus anterior were relatively higher than that of other muscles. However, in both groups, the EMG composition ratio of the serratus anterior became much more predominant than that of the pectoralis major. In addition, infraspinatus activated greater than pectoralis major. These results showed that the push-up plus exercise is effective to selectively strengthen the serratus anterior for both individuals with and without winging scapular, but not equally effective for other shoulder stabilizers.
