Nurses in today's challenging health care settings need to be skilled critical thinkers and clinical experts. The nurse must be able to use a broad knowledge base to mobilize resources, coordinate actions and evaluate outcomes in complex new situations. So the national licensing examination for registered nurses is change to improve the quality of professional competency of nurses in Korea. Prior to this, learning objectives should be developed and improved periodically. The purpose of this study is to describe the nursing competency to provide base line data for developing learning objectives in adult health nursing. This study was conducted by means of a questionnaire which was developed by the researcher after reviewing the literature. The questionnaire was based on learning objectives which were developed by a nation-wide nursing faculty majoring in adult health nursing. The subjects were 45 nurses in a middle level hospital. The collected data were treated using SPSS Win 7.5 Statistical Package so as to obtain such descriptive statistics as mean score, frequency, and to test reliability test, nonpar-Friedman test. To summarize the major findings in this study, it showed the scope of nursing competency and can guide the direction of study and methodological criteria to develop learning objectives. Recommendations for further research are: firstly, it is necessary to state learning objectives with learners' behavioral terminology; secondly, to overcome locality in scope of this study, there is a need to analyze with nation-wide sampling by an in-depth statistical analysis; thirdly, because the subjects of this study are mostly three-year graduate nurses, there is a need to compare this study with other studies of different subjects.

Background: Epidermal growth factor-like domain multiple 7 (EGFL7), recently identified as a secreted protein regulated by oxygen exposure, plays a critical role in promoting metastasis of hepatocellular carcinoma (HCC). Transcatheter arterial embolization (TAE) is widely used for treatment of HCC, resulting in hypoxia in tumors and surrounding liver tissues. Accordingly, we proposed the hypothesis that there could be a relationship between expression of EGFL7 and response to TAE. Materials and Methods: We established a rabbit VX2 liver tumor model using percutaneous puncture technique guided by computed tomography. TAE and sham embolization were performed and the results were confirmed by MRI 3 weeks after inoculation. We investigated the EGFL7 expression of the two groups at 6h and 3 days after intervention by means of immunohistochemistry and Western blotting. Results: Immunohistochemical staining demonstrated that the levels of EGFL7 protein significantly increased in the TAE-treated tumors compared with the control group at 6 hours (P=0.031) and 3 days (P=0.020) after intervention. Meanwhile, the relative EGFL7 protein detected in TAE group also up-regulated compared with the control group at 6 hours (P=0.020) and 3 days (P=0.024) after intervention. Conclusions: This study reveals an increase of EGFL7 expression in rabbit VX2 liver tumors after TAE. The role of EGFL7 in HCC, especially its biological behavior after TAE, needs further investigation.

As Multi-National Enterprises expanded their investments to foreign countries, numerous controversies and disputes arose from their negative impacts, such as violations of human rights and damage to the environment of the host countries. In response, International Organizations such as the OECD have considered various ways to prevent these negative impacts and search for more efficient dispute resolution methods. It is recognized that the OECD Guideline is one of the tools they created for this purpose. The OECD Guideline is contrastable from Corporate Social Responsibility (CSR) initiatives which are regarded as a corporation's charity activities apart from their core business functions. However, Responsible Business Conduct (RBC) like the OECD Guideline can be understood as a concept moving forward from CSR, due to its requirements that corporations carry out their duties in a responsible manner within the field of their core business, such as tax, global supply chain or consumer protection. RBC which is binding in nature, has even been implemented through legislation in developed countries such as the USA, France, Switzerland, and the UK. The discussion in Korea, however, has not reached that level. Discussions for legislation center singularly on CSR efforts, with a dialogue only recently forming around the topic of legislation concerning RBC. Small and medium sized enterprises (SMEs) who lack certain financial and other resources to adequately develop RBC initiatives may find this more obstacles to implementation through legislated RBC, than if it were presented in Korea through other means. It's necessary to admit that RBC is a critical issue in international business. However, time is required to consider its application directly to SMEs.

Service marketing is the important part in relationship marketing researches because it can make not only a functional aspect, but a social connection with customers as well through the interactive process in service encounters. Therefore, we have to examine whether or not customers' strong emotional bonds which can be created by the interaction in service encounters have influences on the variables related to relationship marketing in service. As results, social rapport and friendship as customers' strong emotional bonds were stimulated by a relational antecedent(communication), and eventually could effect on customer loyalty as a relational outcome positively. It means that customers' strong emotional bonds are critical components to lead relational outcomes in relationship marketing of service. Also, It suggests that customers' strong emotional bonds should be considered in the process from the relational efforts to relational outcomes.

Spectrum sharing between wireless systems becomes a critical issue clue to emerging new technologies and spectrum shortage. Recently, IMT system has been allocated in the same frequency C band (3400-4200MHz) along with FSS services on co-primary basis which means that harmful. interference probability may be inspired. In this paper, to estimate the spectrum sharing between IMT and FSS systems, I propose the minimum separation distances as a sharing criterion of I/N=-10dB using the interference to noise ratio(I/N) received at the reference FSS earth station from IMT multiple base station. Especially, same results imply that I/N values can be greatly reduced with MMO SDMA interference mitigation technique of IMT base station so that FSS and IMT systems can co-exist in the sam e frequency with appropriate separation distance.

The Head Related Transfer Function (HRTF) means a process related to acoustic transmission from 3d space to the listener's ear. In other words, it contains the information that human can perceive locations of sound sources. So, we make virtual 3d sound using HRTF, despite it doesn't actually exist. But, it can deteriorate some three-dimensional effect by the confusion between front and back directions due to the non-individual HRTF depending on each listener. In this paper, we proposed the new algorithm to reduce the confusion of sound image localization using human's acoustic characteristics. The frequency spectrum and global masking threshold of 3d sounds using HRTF are used to calculate the psychoacoustical differences among each directions. And perceptible cues in each critical band are boosted to create effective 3d sound. As a result, we can make the improved 3d sound, and the performances are much better than conventional methods.

The purpose of this study was to clarify the cultural characteristic of dress and adornments by examining articles on dress adornments and related items in Korean newspaper over periods historically and objectively by means of content analysis. This study attempted to at-tain a macro-cultural view by analysing to at-tain a macro-cultural view by analysing closely the cultural characteristics of dress and adornments as a micro-cultural system through culturally based model suggested by hamilton. The two-hundreds and eighty articles on dress and adornments were selected from newspapers(most by form Chosun Ilbo and partly from Maeil Shinbo) pulished between 1920 and 1990. The results were as follows: 1. The culture of dress and adornment received much attention during the 1930's and 1960's and little during 1950's. 2. Various cultural characteristics of dress and adornments appeared on and after 1960's: reporting more foreign news items showing foreign-oriented and future-oriented features showing cultural relativism. In the 1920's and 1970's the contents of news items on dress and adornments show the most common- mass- oriented character. Foreign-oriented cultural tendencies in cloth-ing were increasing during from 1960's to 1970's but the tendencies were turned to rather tradition-oriented features on and after 1980's compare with 1960's-1970's. Advisory critical articles on dress and adornments were small in number and insignificant but compare with other periods these received much atten-tion during the 1920's and 1980's. 3. Ideological components received much at-tention on and after 1920's to 1990. Techo-nological components received much attention during 1920's and little during 1960's. The social structural components received a little attention on and after 1920's-1940's and 1990. 4. News items on women's dress and adornments received much attention from the 1920's to 1960's and news items on both men's and women's dress and adorments were in-creasing and received much attention on and after the 1970's. 5. The pragmatic cultures were mostly re-lated to techonological components and evaluative-normative culture were mostly re-lated to ideological and social structural components. In the light of these results dress and adorments as a cultural sub-system comprise a dynamic inteacting system that articulated directly with the macro-cultural system.

The development of bars and sediment sorting processes in the braided channels with the mixed grain sizes are investigated experimentally in this study. The sediment in the steep slope channels discharges with highly fluctuation. However, it discharges with relatively periodic cycles in the mild slope channels. The characteristics and amplitudes of the dominant bars are examined by double fourier analysis. The dimensionless sediment particle size decreases as the longitudinal bed elevation increases. However, the size increases as the longitudinal bed elevation decreases. As the dimensionless critical tractive force in the surface layer ratio to the force in the subsurface layer increases, the surface geometric mean size of sediments and the dimensionless sediment particle size decrease. This means that coarse matrix is formed with the dimensionless tractive force by the sediment selective sorting.

This paper attempts to present critical issues of the information society and an alternative research addressing the challenges of ensuring that ICT is applied in ways that are enabling and responsive to social contexts in which people live their lives. Drawing the question of why insights arising from the mainstream vision are rarely useful in policies, the study highlights some developmental paradigms linked to ICT. It explores how ICT is seen as a means to development, and elaborates on the limitations of how current issues are related to the quality of life. The results indicate that ICT reduces quality of life while economic growth entails the opposite. The research framework here involves some meaningful components of cultural residues: independence, risk-taking, government responsibility by mapping how the level of ICT is distributed in the topology of values around the world. Moving to the next phase, ICT policy design and implementation need to be set up practically in a broad perspective that can be pursued by those concerned with social and technological innovation.

Knowledge ecosystem means a dynamic knowledge circulation, including knowledge creation, exchange and sharing and utilization. It is also the field of knowledge practice, which creates interactions in knowledge exchange between people and groups. The key premises of knowledge ecosystem, based on the nature of general ecosystems, can be characterized as follows: first, it primarily focuses on social networks between people and organizations participating in the process of knowledge circulation; secondly, knowledge ecosystem thrives on diversity of knowledge; and thirdly, it is significant for selection of valuable knowledge and adoption of appropriate knowledge. This review attempts to make a systematic examination of a wide range of existing studies on knowledge ecosystem. In so doing, it is expected to provide a basis for further inquiry into more critical and complicated issues. Although the scarcity of existing research-at least those in Korea-may limit the implications of findings, this review offers a set of suggestions for future research.
