Narrative runs through the entire human life. 'Narrative' is a means of understanding and experiencing human life. The past, the present and the future are not disconnected. The past is open to the future. The future defines the meaning of the past, and the past rreturn as the horizon of life. Past, present and future temporality functions as a Narrative. Records reproduce the past time as Narrative, and recount the past according to reading behavior. Reality and records complement each other with a cyclic and dialectic structure. This paper examines the relationship between reality and records. This paper applies Paul Ricoeur's Hermeneutics to records as a tool to examine the relationship between reality and record. We want to look at how records interpret and relates to reality, and how social justice of collective memory should be should be achieved against them.

This study was performed to investigate the effects of Bambusae Caulis in Liquamen (bamboo extract) on the changes of antioxidant enzymes and histopathological changes of liver and kidney in mice when administered in different dosages. The experimental groups were divided into four. For control group, 0.9％ NaCl (0.2 ml/25 g B.W.) and for experimental groups, 5% (H1 group), 10% (H2 group), and 20%(H3 group) bamboo extract diluted with 0.9％ NaCl, were administered (0.2 ml/25 g B.W.) respectively for 28 days at an interval of 48 hours. MnSOD activities were increased in H1 group (46%, P<0.05), H2 group (40%, P<0.05), and H3 group (34%, P<0.05) as compared to the control group. CuZnSOD activities were increased in H1 group (11%, P<0.05), but were decreased in H3 group (13%, P<0.05). The activities of catalase were decreased in H1 group (39%, P<0.05), H2 group (34%, P<0.05), and H3 group (31%, P<0.05) as compared to the control group. Histopathological observation revealed ballooned hepatocytes in the pericentral and periportal veins of H1 group. More ballooned and injured hepatocytes than in H1 group were observed in the H2 and H3 groups. Detachment of endothelial cells of the central vein was observed in the H2 and H3 groups. These results indicated that bamboo extract developed dose-dependent changes in antioxidant enzyme activities and developed histopathological changes of liver and kidney.

A numerical variation and abnormalities were studied on egg bags and embryos of Korean salamander, Hynobius leechii from agricultural habitat. The teratogenic and toxic effects of fungicide benomyl were also investigated with early embryos from non-agricultural habitat. We collected 144 egg bags from agricultural region, and 3418 of early embryos were contained. The lengths of egg bags were varied from 10 to 23 cm and the most frequent length was 19 cm. The number of embryos was varied from 7 to 43, and the most frequent range was 22 to 26. Spontaneous abnormalities were occurred in 406 embryos among 116 egg bags, and 24 kinds of external abnormalities were found. Individuals showing severe external defect were histologically studied and they showed optic dyspalsia, thyroid carcinoma, somatic muscular dysplasia, partial biaxial structure, decrease of red blood cells in the heart, cephalic degeneration and intestinal dysplasia. 385 embryos from non-agricultural region were exposed to 200 nM${\sim}$ 1 ${\mu}$M of benomyl at blastula or gastrula for 12 days. All embryo were dead in the concentration of 1 ${\mu}$M (LD$_{100}$) and 75% of embryos were dead in 800nM of benomyl. Speciflc effect due to benomyl was acrania or cephalic dysplasia and this restult suggests that the benomyl inhibit stongly to the development of neural tissue. These abnormal developments may be caused by antimitotic action, inhibition of tubulin complex, destruction of microtubule, inhibitions of neurulation and closing of neural fold, and by the inhibition of the movement of neural crest cells.

In this study we analyzed and interpreted the phenomenologlcal characteristics and meanings of water space in religious architecture through field studies and phenomenologlcal approaches, focusing on the religious architecture Introducing water space in contemporary architecture. The phenomenological experience elements of the research ate light, time, place and context. As the results of this study, first, light as a phenomenological element not only induces a contrast and change between light and the shadow in architectural space and various changes of light in inner space, but also operates as an element which expresses building features outward with time. Second, time as a phenomenological perception experience makes us feel changes of the environment and physical properties and experience space visually and physically. The continuity of time shows the change of a day, night and daytime and seasons. Third, water space makes the sense of place more remarkable, connected closely with surrounding nature In outer space, and creates a new space. Fourth, water space is a contextual element which harmonizes with surrounding environment by connecting surrounding natural environment with architectural space. Fifth, water space in religious architecture is a symbolic and central element, and emphasizes the atmosphere of architectural space. In addition, it makes the people who experience water space perceive the place by triggering sensitive response.

The purpose of this study was to understand the meaning and essence of leisure activities experienced by older females in rural communities and, in reference to that, to provide basic data to help develop health-promoting nursing intervention programs by investigating the indications of leisure and its effects on older individuals' life process. The qualitative research method of van Manen's Hermeneutical analysis and Phenomenological research are useful to study the true meaning and nature of experiences inherited from their language, belief, culture and social traditions. Consequently, the leisure that the women from the rural community were found to have experienced came down to a total of seven themes or activities: (a) to overcome loneliness through social interaction and get-togethers; (b) to achieve balance between body and mind by engaging in physical activities; (c) to try and help ease the burden on one's children; (d) to simply kill time; (e) to find oneself small pleasures; (f) to learn something new and feel proud; and (g) to live one's life as maintaining communication with the outside world. The study herein confirmed that the female elderly in rural area spend their free time on appreciating the nature, maintaining health and social interaction and hanging around with the peers of similar age to overcome economic woes and the feeling of estrangement unique in the social and economic context of rural communities.

유전자 발현에 있어서의 조절작용은 유전자간의 복합적인 상호작용의 결과에 기인한다. 따라서 이러한 현상으로부터 기능적으로 연관된 유전자 군을 식별하기 위해서는 단일 유전자보다는 복수의 유전자군의 발현패턴을 대상으로 하게 된다. 이 경우 발현패턴의 시간에 따른 다양하고 복잡한 특징들은 은닉변수학습 모형을 이용하므로서 보다 명확하게 표현될 수 있고, 유사한 기능을 가진 유전자 군을 탐색 하는데에 효과적으로 이용될 수 있다. 본 논문에서 제시된 은닉변수학습 모형은 이스트 Cell Cycle 데이터에 적용한 결과 특정 조절유전자에 대하여 생물학적으로 연관된 유전자 군을 찾는 데에 다른 방법과 비교하여 효과적임을 보일 수 있었다.

막분리에 있어 막오염 현상은 공정의 경제성을 좌우하는 중요한 요소이다. 이에따라 막오염에 따른 플럭스 변화를 예측하기 위한 다양한 방법을 시도하고 있다. 그러나 대부분의 동력학적 해석식들은 여과초기에만 적용되는 단점이 있었다. 최근에는 콜로이드 입자에 의한 막오염 과정을 그대로 모사하여 여과개시 후 상당한 시간 후의 플럭스를 예측하려는 시도를 하고 있다. 그러나 지금까지 연구된 모델들은 2차원입자를 사용하거나 혹은 단일입자분포를 갖는 3차원입자를 사용한 것들이었다. 2차원 모사인 경우 세공막힘현상을 설명할 수 없으며 3차원 단일분포 입자시스템은 현실과는 거리가 먼 단점이 있었다. 이에따라 본 연구에서는 다중분포(multi-disperse)를 갖는 입자의 정밀여과 (microfiltration)를 모사하여 시간에 따른 플럭스의 변화를 예측해 보고자 하였다.

This study was conducted to discover the meaning and the essential structure of the experiences of nursing students' introductory clinical practice. The participants were eight nursing students who had carried out the introductory clinical practice at a hospital. The data was collected from July 15 2019 to July 31, 2019 through focus group discussions and in-depth individual interviews using non-structured questionnaires. The data was analyzed by Colaizzi's phenomenological analysis methodology. The introductory clinical practice experienced by nursing students was categorized as followed: 'Feel worried and concern about expectations at the same time', 'Hospital experience as reality', 'Becoming accustomed to complexed emotion's, 'The first step of becoming a nurse', and 'Preparation for the future'. The five categories were expanded in the same context according to time. The essential structure of the clinical introductory practice experiences of the nursing students revealed by the study is that they begin to practice feeling worried and concerned about expectations, and concern about experience and adaption to various situations, emotions and preparation for the future. Based on the results obtained from this study, it is necessary to develop a realistic and effective education program before starting clinical practice.

This phenomenological study aims to explore Nursing Students' Experiences who have experienced team-based learning (TBL). The purpose of this study is to contribute to fostering professional nurses required in the clinical field by improving the learning outcomes by applying the TBL classes. The study participants were seven students of the nursing department who took TBL classes in adult nursing classes. The data were collected through participating observations and in-depth interviews, and analyzed using Colaizzi's phenomenological methods. As a result of the study, nine conceptual descriptions and five theme clusters were derived. The major theme clusters for the experiences of students were 'Dedication to best results', 'Self-led learning attitudes are formed', 'Becoming a communal knowledge creator', 'Active class time', and 'Meaningless peer evaluation'. Nine conceptual descriptions were 'Doing one's best to fulfill one's role', 'Preparing for the class with the pre-learning', 'Forming confidence through pre-learning', 'Solving problems through interaction with friends', 'Becoming a mentor to each other', 'Working together to resolve issues', 'Intimacy formed', 'A lively class', and 'Peer evaluation with familiarity'. This study contributes to the improvement of the learning outcomes of the nursing students by enabling learner-centered classes and self-led learning, thereby contributing to fostering the professional nursing manpower required in the clinical field.

In this study, Laminaria japonica was used as a substrate for a mixed aerobic microbial consortium. Laminaria japonica is well-known as a representative brown algal biomass possessing advantages of cheap cost, and high productivity and carbohydrate content. A biological saccharification system was established by inoculating and enriching the mixed aerobic microbial consortium. Production of the soluble carbohydrate and reducing sugar at different hydraulic retention times (HRT) was observed. The efficiency of saccharification increased according to the decrease of HRT. The maximum saccharification yield in a continuous biological pretreatment process was 17.96 and 4.30 g/L/day for the soluble carbohydrate and reducing sugar, respectively at the HRT of 1 day. In contrast, the staccharification yield decreased drastically at the HRT of 0.5 day. Experimental results indicate that Laminaria japonica is a promising material for the production of useful products, in particular for the saccharification through a biorefinery process. It can thus be concluded that a continuous biological pretreatment process using a mixed cultivation system can be successfully employed for the biorefinery technology.
