본 연구에서는 실시간 통신 기술을 적용한 온라인 수업 토론 활동의 중층적 구조와 역동적 전개 양상을 개념적 수준에서 분석하였다. 문화역사적 활동이론에 근거하여 온라인상에서의 개별 발화를 활동체제의 산물로 간주하였으며, Alderfer의 욕구 위계이론을 주체의 동기와 의도를 분석하는 틀로 활용하였다. 온라인 수업 토론은 전체로서 하나의 활동체제로 작동하며, 특별히 활동 주체들의 욕구에 따라 기본 방향과 성격이 규정된다. 주체의 존재, 관계, 성장의 욕구에 따라 이들의 수업 토론 활동은 물리/생물적 차원, 문화/제도적 차원, 사회/관계적 차원, 협력적 지식 구성의 차원으로 규정된다. 이는 개별 활동 체제 안에 중층적으로 존재하며, 각자의 관심과 처지에 따라 배열이 달라지고, 동시에 활동체제 간의 협력과 갈등의 요인으로 작용한다. 이를 통해 집단적 토론 활동은 복잡하고 역동적으로 발전한다.

The organic foods is the terminology calling the organic products, the organic livestock and the organic processing food. The value of organic food may be evaluated as the index of the nutrient content, the safety and the health promotion. The reason why consumers prefer the organic food in the market is because the value of health promotion to be obtained through its consumption is expected to be bigger than the expense according to the purchase of organic food. This study has the significance in developing the direct evaluation model like the human biomonitoring method. The hypothesis for this study is summarized, "If the metabolome of metabolic syndrome of decreases, the exposure of substance of health harm decreases, the number of hospital care decreases and the quality of life shall be improved if the organic food is incepted in the long term and the health care is managed well". The consumer's cooperative and the health consumer's cooperative select the experimental group of 100 persons and the comparative group of 100 persons in 5 areas in the whole country at the same time to verify this hypothesis. Its rate of change is compared and analyzed by measuring the blood and urine of each biomarkers such as the exposed agriculture pesticides, the nitrate in the body at intervals of 2 months for 1 year. Also, by letting participants in the experiment record the major activity such as the dietary intake and the exercise, etc., in the questionnaire and the performance evaluation form, the statistical analysis for the correlation of this with the metabolome, etc., is conducted. The time that is called minimum 1 year and a lot of expense are required to implement this model. Accordingly, the cooperative study by composing the consortium of the interdisciplinary and the interagency is desirable.

Purpose: The purpose of this study was to identify nurse's role through job analysis of nursing duties for nurses working on East Asia traditional medicine wards. Methods: Major steps in the study included a literature review, description of job activities of nurses on oriental medicine wards, comparative description of the literature, expert tests of validity of derived duties and tasks, and investigation of importance, difficulty and frequency of duties on job list. Results: The job of nurses on oriental medicine wards was classified into 12 duties, 59 tasks, and 295 task elements. The 12 duties were nursing assessment, nursing diagnosis, nursing planning, nursing implementation, nursing evaluation, supplies management, management of human resources, management of environment, management of documents, formation of cooperative relationships, self-development, and nursing activity in oriental medicine. 'Formation of cooperative relationships' was the duty ranked highest for importance (4.34), 'self-development' was ranked highest for difficulty (3.47), and 'Formation of cooperative relationships' was ranked highest for frequency (4.21). Conclusion: Basic education for nurses on an oriental medicine unit is necessary for the performance of oriental nursing to be considered as a specialized field. This study contributes to human resource management in the oriental medical hospital.

The structural and functional aspects of ervatamin B were studied in solution. Ervatamin B belongs to the $\alpha+\beta$ class of proteins. The intrinsic fluorescence emission maximum of the enzyme was at 350 nm under neutral conditions, and at 355 nm under denaturing conditions. Between pH 1.0-2.5 the enzyme exists in a partially unfolded state with minimum or no tertiary structure, and no proteolytic activity. At still lower pH, the enzyme regains substantial secondary structure, which is predominantly $\beta$-sheet conformation and shows a strong binding to 8-anilino-1-napthalene-sulfonic acid (ANS). In the presence of salt, the enzyme attains a similar state directly from the native state. Under neutral conditions, the enzyme was stable in urea, while the guanidine hydrochloride (GuHCl) induced equilibrium unfolding was cooperative. The GuHCl induced unfolding transition curves at pH 3.0 and 4.0 were non-coincidental, indicating the presence of intermediates in the unfolding pathway. This was substantiated by strong ANS binding that was observed at low concentrations of GuHCl at both pH 3.0 and 4.0. The urea induced transition curves at pH 3.0 were, however, coincidental, but non-cooperative. This indicates that the different structural units of the enzyme unfold in steps through intermediates. This observation is further supported by two emission maxima in ANS binding assay during urea denaturation. Hence, denaturant induced equilibrium unfolding pathway of ervatamin B, which differs from the acid induced unfolding pathway, is not a simple two-state transition but involves intermediates which probably accumulate at different stages of protein folding and hence adds a new dimension to the unfolding pathway of plant proteases of the papain superfamily.

Background: Antimicrobial peptides (AMPs) have been identified as promising compounds for consideration as novel antimicrobial agents. Objectives: This study analyzed the efficacy of cecropin B against Haemophilus parasuis isolates through scanning electron microscopy (SEM) and atomic force microscopy (AFM) experiments. Results: Cecropin B exhibited broad inhibition activity against 15 standard Haemophilus parasuis (HPS) strains and 5 of the clinical isolates had minimum inhibition concentrations (MICs) ranging from 2 to 16 ㎍/mL. Microelectrophoresis and hexadecane adsorption assays indicated that the more hydrophobic and the higher the isoelectric point (IEP) of the strain, the more sensitive it was to cecropin B. Through SEM, multiple blisters of various shapes and dents on the cell surface were observed. Protrusions and leakage were detected by AFM. Conclusions: Based on the results, cecropin B could inhibit HPS via a pore-forming mechanism by interacting with the cytoplasmic membrane of bacteria. Moreover, as cecropin B concentration increased, the bacteria membrane was more seriously damaged. Thus, cecropin B could be developed as an effective anti-HPS agent for use in clinical applications.
