Atmospheric rivers, which transport large amount of water vapor from mid-latitude to the inland, are an important driving force of water cycle and extreme hydrologic phenomenas. The main objective of this study is to analyze the hydrological impact of the AR landfalls on the Korean Peninsula in 2000 - 2015. The result showed that the AR is closely related to the characteristics of precipitation, water level and runoff in the Korean Peninsula. The landfalls of the AR affected about 57% of annual precipitation on the Korean Peninsula, and had a greatest impact on the summer rainfall. It also affected the water level and runoff at the five major rivers of Korea, and water levels exceeding the thresholds of flood warning were observed when the AR landed. Moreover, it was found that the runoff above the third quartile with AR landfalls. These results suggest that the AR not only has a significant influence on the hydrological characteristics of the Korean Peninsula, but also have a close relationship with the extreme hydrological events like floods. The results of this study are expected to be used as the reference for the analysis of the impact of the AR on the various fields in the Korean Peninsula.

The purpose of this study was to investigate relationships between self-care knowledge and compliance of ischemic stroke patients with diabetic. The participants were 117 ischemic stroke patients with diabetics who were outpatients at the P university hospital. Data were collected from July 1 to August 31, 2013. Data were analyzed using SPSS 18.0., specifically descriptive statistics, t-test, ANOVA, and Pearson's correlation analysis. Total mean score and correct answer ratio of self-care knowledge were 14.69 points, 63.9%. Total mean score and compliance ratio of self-care compliance were 2.24 points, 44.8%. The correlation coefficient between self-care knowledge and compliance was a significant positive correlation (r=.54, p<.001). Among sub-elements, diet(r=.24, p=.011), medication(r=.43, p<.001), living habits(r=.19, p=.042) and cautions and warnings(r=.45, p<.001) were significant positive correlations. Based on the results of this study, we need to develop integrated nursing intervention education programs for self-care knowledge and compliance promotion of ischemic stroke patients with diabetic.

Rainfall is widely recognized as a major landslide-triggering factor. Most of the latest landslides that occurred in South Korea were caused by short-duration heavy rainfall. However, the relationship between rainfall characteristics and landslide occurrence is poorly understood. To examine the effect of rainfall on landslide occurrence, cumulative rainfall(mm) and rainfall intensity(mm/hr) of serial rain and antecedent rainfall(mm) were analyzed for 18 landslide events that occurred in the southern and central regions of South Korea in June and July 2011. It was found that all of these landslides occurred by heavy rainfall for one or three days, with the rainfall intensity exceeding 30 mm/hr or with a cumulative rainfall of 200 mm. These plotted data are beyond the landslide warning criteria of Korea Forest Service and the critical line of landslide occurrence for Gyeongnam Province. It was also found that the time to landslide occurrence after rainfall start(T) was shortened with the increasing average rainfall intensity(ARI), showing an exponential-decay curve, and this relation can be expressed as "T = $94.569{\cdot}exp$($-0.068{\cdot}ARI$)($R^2$=0.64, p<0.001)". The findings in this study may provide important evidences for the landslide forecasting guidance service of Korea Forest Service as well as essential data for the establishment of non-structural measures such as a warning and evacuation system in the face of sediment disasters.

Analysis of water-level fluctuation due to goundwater-surface water interaction in coastal aquifers is carried out by numerical modeling. The conceptual model used in this study has a stream boundary and a tidal boundary that forms a right angle and the stream partially penetrates the aquifer. We analyzed the effect of each boundary and the simultaneous effect of the two boundary conditions. The area of influence caused by the stream boundary increased during the simulation, while the influence zone of the coastal boundary was relatively constant. The groundwater level near the zone where two boundaries meet may rise by the action of combined effect of the two boundaries or may not change by cancelling the effect of each boundary. Thereafter, care must be taken when hydraulic parameters are estimated using sinusoidal oscillations of hydraulic head in coastal aquifers. Sensitivity analysis is employed to develop insight into the controls on groundwater level fluctuations. In this study our analyses focused on the effect of conductance and the stream width to the aquifer nearby.

Lactoferrin, an ion-binding 80-kDa glycoprotein, has been suggested to have many biologic activities, such as facilitating ion absorption and having antimicrobial and anti-inflammatory effects. Several of these activities are likely to only be facilitated by human lactoferrin because they depend on the binding of human lactoferrin to specific receptor. To produce recombinant human lactoferrin to animal foods using transgenic silkworm, Bombyx mori L, we have cloned and sequenced the cDNA encoding for a human lactoferrin (HLf) from the mRNA in mammary tumor line (GI-101). As a result, the 2.5-kb fragment of HLf gene was cloned with pGEM-T vector and then this fragment was sequenced. In the nucleotide sequence analysis, single open reading frame of the 2,136-bp encoding for a polypeptide of 712 amino acid residues was detected. On the other hand, we constructed a recombinant plasmid(pPT-HLf), containing human lactoferrin gene for germ line transformation of the silkworm using a piggyBac transposon-derived vector. A nonautonomous helper plasmid encodes the piggyBac transposase. Approximately 6.7% of individuals in the G0 silkworms expressed green fluorescent protein (GFP). PCR analyses of GFP-positive silkworms (G0 and G1) revealed that independent insertions occurred frequently. Furthermore, Western blot analysis showed that the recombinant HLf expressed in hemolymph has the same molecular weight (80 kDa) as a native protein. On the basis of these experiments, expression of HLf in next generation of transgenic silkworm is now in process.

In these days, science is too complex and comprehensive scientific practices to be reduced to scientific knowledge. Also it's actors go beyond the limit of scientist society to the broad range of supporting system scientific journalism, education, and business. Science is very important cultural practice of our times. This Study focus on the effect of interdisciplinary approach in understanding modern science culture. First, this paper suggest the approach of public understanding of science(PUS) as a framework PUS has provided new perspectives for the relation of scientific knowledge and understanding. Traditional approach(so-called 'deficit model') regarded understanding as mere transportation of scientific knowledge. So it may be called 'knowledge-oriented approach' to understanding. But PUS consider understanding process of 'dynamic reconstructing' which is occurred in complex socio-cultural context. Second, this article analysis the Korea University STS course(2002-2003) 'Science Technology & Society' as the case study. The case study examine how interdisciplinary approach help students to understand 'sciene in the making'.

With the change of society and the rapid development of science and technology, the direction of future education and the functions of schools have changed. Also the roles and tasks of teachers are changing rapidly. As Germany entered into the 21st century, many discussions let to a consensus on the direction of future education and schooling withholding a sense of responsibility and solidarity for the education of all members of the society. As a result, standards for the training of general teachers and teachers for special education were presented. The purpose of this study is to compare the standard contents of teacher training for special education in Germany with the qualification criteria for special school, teachers in Korea, focusing on evaluation and giving as well detailed information on the examination of teachers for special school, as on basic subjects for the qualification of special school teachers for special education in Korea will be explored. As a result, the content of this study can be summarized by four items. The first one is dealing with the creation of a consciousness of solidarity and a sense of responsibility among the members of the society for the future education and the role of schools and teachers. The second item ist about including the capacity and competence of teachers in the restructuring of the school and in the minimum standards of teacher training for special education. Third, the specificity of each state (provincial and local) is considered in the content of standards for teacher training. Fourth, standards for teacher training are linked to each other, previous teacher education, trainee teacher education, and current teacher education.

With progress of the sound and moving picture recording technology, sound and moving picture have been a tool for evidence and memory on human activities. Accordingly, in archival science the importance of oral history as a record is disseminating and the production of oral record is carried out actively. But for producing oral record in archival institutions, the identity of oral record need to be established more firmly. Archival science is the task which delivers the current appearance of life to future through records. Therefore producing oral record in archival science must have unique characters. And archival science is the task which is building current memory. Therefore the identity of oral more firmly. This article intends to explore the meaning and role of oral record from a perspective of archival science. All these days, the theories and methodologies had been developed focusing on written records mainly in the deep-rooted influence of positivism. But as it is enabled the creation and preservation of records through 'speech', it need to be noted that oral record is the very core of tool for delivering the current society shape and collective memory. Therefore this article will intend to explore the meaning and role of oral record as a part of effort to establish the identity of oral record.

This study aims to conceptualize characteristics of the Korean traditional dance, and to categorize and analyze the recognition of experience of passing down education of Seungmu(Buddhist Dance), Salpurichum(Exorcism Dance) and Taepyeongmu(Dance of Peace). Dividing into groups of two: an experienced person twenty years or more in the Korean dance and a person who completed the traditional dance three years or more, three groups were selected. We connected the characteristics of the traditional dance experienced in passing down education with the recognition experience in the training courses. Categorizing thematically the process and the recognition of experience in the passing down education program, we attempted mutual group discussion and inductive area analysis on the basis of in-depth interview, tutorial discussion and analysis contents. As a result of this study, first, the characteristics of the Korean traditional dance that graduates of the program by repertory empathize were the experience of the sinmyung(the excess of mirth) and improvisation, the supreme self-controlling beauty and the best beauty of expression. Second, the recognition of experience in the passing down education program runs as follows: Interacting in the centre of the process, new education system for transmission, and formation of social discourse for appreciation. Conclusionally, the experience and the new vision for transmission of passing down education of the traditional dance are required to be based on the appreciation of the rationality of mutual communication and recognition of experience.
