Glutathione(GSH) in biological samples was determined by high performance liquid chromatographic(HPLC) method with fluorescence detector(FLD) after monobromobimane(MBB) or 4-fluoro-7-sulfobenzofurazan(SBD-F) derivatization. The detection limit of $0.03{\mu}g/mL$ was obtained after MBB derivatization, derivative of MBB was about 200 times more sensitive than that of SBD-F. N-acetylcysteine was used as internal standard and tetrabutylammonium ion as counter ion for better separation. The determination by ion-pairing chromatography after MBB derivatization was characterized by linearity in the range between $0.08{\sim}8.33{\mu}g/mL$ with a good correlation coefficient of 0.998. By precision test appeared relative standard deviation at less than 5% at three different concentrations. This method can be used for the analysis of GSH in plasma and tissue.

A research project entitled "Discovery of Korean Indigenous Species" was launched in 2006, and has been carried on as a continuous project until now. The main purpose of this project is to find undiscovered species on the Korean peninsula and ultimately register these species in the "National List of Species of Korea". In this paper, we present 79 unrecorded species of the Korean metazoans. All species were obtained from the final reports of "Discovery of Korean Indigenous Species" which were performed during the first five years of the project, 2006 to 2010.

The purpose of this study is to analyze user requirements of photovoltaic generating facilities for detached houses. For the analysis, 202 households that installed photovoltaic generating facilities to conduct a survey. According to the survey results, users mainly demanded 'Reduction in self-burden amount' and 'Maintenance Services.' In addition, when conducting 'Education for photovoltaic generating facilities', they highly wanted to participated in it. Results on the installation status of photovoltaic generating facilities are as follows: Of locations where photovoltaic generating facilities are installed, the most households installed them on the roof, 54%. As for the angle in which photovoltaic module is installed, the range of $25{\sim}35^{\circ}$ was the most common and in the case of installation direction, southern exposure accounted for the rate of 93%. The monthly average generation of households surveyed is approximately 320kWh. Research on technology and policy to address user requirements shown in this study is deemed necessary in the future.

This study explored what the phenomenon of 'Chinmokjil(Socializing Behavior)', which online community is seriously wary of, implies and actually affects the online community. Interviews were conducted for 13 people who had experienced Chinmokjil in online communities, and the results were analyzed by qualitative analysis. First, Chinmokjil is conceptualized as 'privatization or privately organizing of online community' Second, the actual phenomenons of Chinmokjil are sub-categorized as 8 categories Third, the ultimate negative impacts of Chinmokjil are sub-categorized as 3 categories. Based on the results, it can be explained that the unique norms of communities in online are different from those in offline.

Purpose: This study was conducted to identify the nature the research trends of articles published in the Journal of Korean Academy of Fundamentals of Nursing (JKAFN). Method: Comparison analysis between articles in JKAFN (Volume 13, Number 1-3) and articles in the Journal of Korean Academy of Nursing (Volume 36, Number 1-3, 5-7) based on knowledge development classification was used to identify the nature of research trends in JKAFN. Results: Based on comparison with Journal of Korean Academy of Nursing, research trends in JKAFN were dominant; in personal knowledge in the pattern of knowing in nursing, in the desiderative focus in cognitive needs for nursing epistemology, in advancing of various aspects of nursing in the focus of knowledge, and practice domain in the domains for nursing. Conclusion: The major focuses on research trends in JKAFN were nursing practice, actions of nurses in practice and practice guideline applicable in nursing education.

The effectiveness of joint operations depends on Jointness based on interoperable elements of participating forces. Many specialists have actively done research studies on interoperability measurement models with the goal of straightforward way of measuring and then have improved the interoperability of elements based on DOTMLPF-p (Doctrine, Organization, Training, Materiel, Leadership & Education, Personnel, Facilities, Policy) in the forces. After the survey of 16 interoperability measurement models, we have concluded that most of them applied only a small portion of DOTMLPF-p elements explicitly or all portions of DOTMLPF-p elements implicitly. In this study, we propose a conceptual interoperability measurement model for applying all DOTMLPF-p elements explicitly. And it can evaluate not only the level of interoperability among forces but also level of jointness for joint operations.

The purpose of this study is to find out the usefulness of color contrast program for 50 high school students through comparing the traditional class and the class using the entry software : understanding, utilization, satisfaction, and interest. The results of the study were as follows: First, in the case of the class results, there were no limitations on colors due to materials in the class using the entry software, so students used various colors that match the theory. Second, the activity class using the entry software showed a positive response in terms of utilization, satisfaction, and interest except for the comprehension area, compared to the traditional class using the paper activity. Therefore, this study proved the effectiveness of the practice activity using the entry software in the color management class.

The industrial community in a metropolis has played an essential role to keep business in a large city. This paper aims to analyze the realities of trade network among enterprises at Buksungro Tools Commercial Cooperative in Daegu. The urban style industrial community is found at Buksungro in Daegu. There are more than one hundred small-sized enterprises. Major trades among enterprises are occurred within and/or by the area. The long-term trade networks within the Buksungro Tools Commercial Cooperative have played the key role to maintain the industrial community. The trade relationship has depended on business networks based on social capital rather than commercial mechanism. The trade networks have been established through credit transactions as well as handling troublesome orders. The trade networks help to transfer technology and to learn the tacit knowledge among firms. The long-term trade networks are more influenced by the social accessibility than spatial accessibility.

Since the environmental redesign project for crime prevention was first implemented in Bucheon City in 2005, the same projects have been actively planned or progressed not only in the metropolitan area but also in local governments across the country. While the same overseas business has achieved remarkable results, domestic business has not achieved quantitative results. In this study, we analyzed the environmental redesign project for crime prevention in Seogjeong-Dong. In the field of electronic communication exclusion, in the course of business, it was possible to analyze the problems that the costs were increased and the business performance was difficult to be derived due to the inconvenience of the residents due to the inexperience of the business owners and the inefficiency of the facilities.

Advances in computer technology enabled us to simulate the integrated effects of various geomorphic processes on landscape evolution. This review introduces a theoretical framework for 2-dimensional numerical landscape evolution models (NLEMs) which have recently been used for various research purposes. In particular much attention is paid to the approaches deployed to model major geomorphic processes on a geological time scale in previous research. NLEMs can simulate landscape evolution by numerically solving the partial differential equation which represents the relationship among the geomorphic system components (GSCs). Simple process specifications of the relationships among GSCs on a long-term time scale in terms of quantification and attempts to combine processes represent the initial research on NLEMs. Later researchers have taken these simple NLEMs and elaborated on them. Introducing the theories of NLEMs in this review is expected to help researchers trying to utilize or develop NLEMs.
