The objective of this study is to develop and evaluate a Korean threshold runoff computation method. The selected study area is the Han-River basin and the stream channels in the study area are divided into 3 parts; natural channel and artificial manmade channel for small mountainous catchments, and main channel for master stream. The threshold runoff criteria for small streams is decided to 0.5 m water level increase from the channel bottom, which is the level that mountain climbers and campers successfully escape from natural flood damage. Threshold runoff values in natural channel of small mountainous area are computed by the results from the regional regression analysis between parameters of basin and stream channel, while those in artificial channel of small mountainous area are obtained from the data of basin and channel characteristics parameter. On the other hand, the threshold runoff values for master channel are used the warning flood level that is useful information for escaping guideline for riverside users. For verification of the threshold runoff computation method proposed in this study, three flash flood cases are selected and compared with observed values, which is obtained from SCS effective rainfall computation. The 1, 3, 6-hour effective rainfall values are greater than the corresponding threshold runoff values represents that the proposed computation results are reasonable.
The present study examined the effects of Korean white ginseng (WG, Panax ginseng C. A. Meyer) on the learning and memory function and the neural activity in rats with trimethyltin (TMT)-induced memory deficits. The rats were administered with saline or WG (WG 100 or 300 mg/kg, p.o.) daily for 21 days. The cognitive improving efficacy of WG on the amnesic rats, which was induced by TMT, was investigated by assessing the Morris water maze test and by performing immunohistochemistries on choline acetyltransferase (ChAT), acetylcholinesterase (AchE), cAMP responsive element binding protein (CREB) and brain derived neurotrophic factor (BDNF). The rats treated with TMT injection (control group) showed impaired learning and memory of the tasks, but the rats treated with TMT injection and WG administration produced significant improvement of the escape latency to find the platform in the Morris water maze at the 2nd and 4th days compared to that of the control group. In the retention test, the WG 100 and WG 300 groups showed significantly increased crossing number around the platform compared to that of the control group (p < 0.001). Consistently with the behavioral data, result of immunohistochemistry analysis showed that WG 100 mg/kg significantly alleviated the loss of BDNF-ir neurons in the hippocampus compared to that of the control group (p < 0.01). Also, treatment with WG has a trend to be increased the cholinergic neurons in the hippocampal CA1 and CA3 areas as compared to that of the control group. These results suggest that WG may be useful for improving the cognitive function via regulation of neurotrophic activity.
This study is conducted to analyse the process and the pattern of motivation for musical expression in clinical music therapy for the adults in the mental health center. The participant were 8 adults purposive sampling who had more than one year music therapy experience in the mental health center and their age ranged from 27 to 53. A major category derived and analysed from the grounded theory method by Strauss and Corbin. The qualitative analysis indicated that motivation for musical expression in music therapy, which was the central phenomenon in this study, was determined by the music therapist and songs used in the sessions. The central phenomenon was caused by the therapist's friendly attitude, high musical capacity, the familarity of the selected songs and the significancy of the lyrics of selected songs. The levels of reliability about the therapist's personality and musical ability as a professional music therapist and the positive arousal of the songs used in sessions affected as the contextual condition. Spontaneous musical expression in music therapy brought the escape from reality, release of stress and sharing by the intervening condition 'empathy' and this resulted in mood regulation, the instillation of hope and group cohesion. It has been found that there were three types of motivation in music therapy: intrinsic motivation, relationship dependent extrinsic motivation and evasive motivation.

The purpose of this study lies in identifying Korean scientists' dependency on foreign scientific and technical information (STI), with emphasis on investigating the causes and results. Especially, this study intends to investigate the impacts that a growing dependency on foreign STI might have brought and will bring about on the development of indigenous STI in ROK. To the end, the present discussion covers the following specific research questions: 1) what are the major information sources used by Korean scientists to locate STI necessary for research-related activities\ulcorner 2) to what extent do Korean scientists use foreign STI for research-related activates, as compared to the use of domestic STI\ulcorner 3) what are the major factors causing the information dependency among Korean scientists and what are the results of the growing information dependency\ulcorner And finally, 4) what suggestions can be made for ROK to further its indigenous STI development, while minimizing its dependency on foreign STI\ulcorner Survey method, together with citation analysis method, is employed as the major data collection technique. The survey sample consists of 167 most 'representative' Korean scientists selected on the basis of their research productivity. 167 specially-designed questionnaires were mailed and 104 out of 167 were responded. Follow-up interviews were carried out for 32 out of 104 respondents, who returned the questionnaire but did not answer some specific questions. The data collected from these 104 respondents were analyzed on the basis of two distinguished groups namely, junior and senior scientist groups. Among the 104 respondents, 58 a n.0, ppeared to belong to a group of senior scientists (older than age 45 and finished their final degrees since 1980), and 46 belonged to a group of junior scientists (younger than age 45 and finished their final degrees before 1980). The major findings of the present study include: 1) Korean scientists regard 'scientific and technical journals and books'as the most important information source to obtain the recent STI; 2) their dependency on foreign STI, for the purposes of research and teaching, is extremely high (information dependency for research activities is 88.5%, and that for teaching activities 91.2%); 3) the information dependency of junior scientists are higher than that of senior scientists; 4) Korean scientists' growing information dependency is closely related to both small quantity and low quality of domestically-produced STI, and has a statistically significant relationship with their educational background; and finally, 5) in order to theoretically explain the growing information dependency of Korean scientists, a hypothesis - 'chronic cycle of information dependency' was developed and introduced. The present study suggests the promotion of indigenous STI as a desirable alternative to escape from the 'chronic cycle of information dependency. Localization of the imported foreign STI is suggested as a good strategy for the indigenous STI development, and also suggested are STI policies for both success of localization process and promotion of more efficient STI flows at national and international level.
The purpose of this paper is to propose a new security orchestration service model by combining various security solutions that have been introduced and operated individually as a basis for cyber security framework. At present, in order to respond to various and intelligent cyber attacks, various single security devices and SIEM and AI solutions that integrate and manage them have been built. In addition, a cyber security framework and a security control center were opened for systematic prevention and response. However, due to the document-oriented cybersecurity framework and limited security personnel, the reality is that it is difficult to escape from the control form of fragmentary infringement response of important detection events of TMS / IPS. To improve these problems, based on the model of this paper, select the targets to be protected through work characteristics and vulnerable asset identification, and then collect logs with SIEM. Based on asset information, we established proactive methods and three detection strategies through threat information. AI and SIEM are used to quickly determine whether an attack has occurred, and an automatic blocking function is linked to the firewall and IPS. In addition, through the automatic learning of TMS / IPS detection events through machine learning supervised learning, we improved the efficiency of control work and established a threat hunting work system centered on big data analysis through machine learning unsupervised learning results.
This study is to think a new arena of collective play culture at the university campus festival for digital generation used to be individually consuming play in cyberspace. While cyberia is virtual cultural space by providing gigantic platforms in which producers and consumers meet, this space has characterized as individuality and disembodiment, that is why recalling the collective play culture at the off-line. This article is to examine the characteristics and meaning of the recent campus festivals during the history of Korean college festivals, and to analyze proposals of play-contents applied by various theories. The 2016-7' proposals include several kind of board game and experimental theatre sublimed philosophical reflection, which shows a kind of attempt to escape from the cultural industrial logic, however they are characterized by Ilinx(drinking culture) and Alea(board game) emphasized more than Agon, and Mimicry combined with paidia rule strongly. Under the neoliberalism, college students' gloomy reality is represented emasculating of the structure of competitions in the context of an unreal world and Mimicry of experience stay in front of the limen before entering the embodiment.
In 1997, 180 countries signed the Kyoto Protocol in Kyoto, Japan. The Kyoto Protocol came into force in February 2005. The agreement calls for industrialized nations to cut greenhouse gas emissions by 5 percent from 1990 levels by 2008 to 2012. One of those polices is a modal shift that change from road freight to sea, inland waterway and railroad transportation that is eco-friendly. The increase of road freight brings road congestion, accidents, logistic costs, air pollution and greenhouse gases. Railroads are superior than the other modes of transportation in mass transportability, high speed, timeliness, safety and environmental-friendliness, but the railway industry has been pushed behind in competition. Korean railroads were used by passengers and freight transport popularly until the middle of 20th century, however, by the sudden change of logistics environments, a shaving time efficiency being most important, railroad logistic lost its competitive power against the transportation by truck. From the research which sees consequently investigated a various policy, a system and a law about Chinese logistics industry and present condition of the Chinese goods enterprise and instance analysis of the large Chinese corporation that branch out to undeveloped markets led and a Chinese logistics industry and problem point escape hereafter the heightening of competitiveness plan which is rational under prsenting boil.

In scientific argumentation, students can use rebuttals to escape uncertainty, which, in this case, can be defined as a vague and fuzzy feeling about other students' explanations. As rebuttals can play a critical role in the sophistication of arguments and the alleviation of uncertainty, this study aims to understand the dynamics of uncertainty and rebuttals by exploring the context of the uncertainty experienced by elementary school students in the argumentation of "Why did the kidney beans not germinate?" and to get insights based on the research results. Twenty fourth-grade students and their homeroom teacher in Kyong-Ki province, South Korea, took part in the research. Students engaged in argumentation in five small groups of four students. The researcher collected qualitative data through video transcriptions, student interviews, and field notes. In the data analysis, the researcher employed the constant comparative method to explore in what context students experienced uncertainty and how they used rebuttals. The results of this study were as follows: First, students tried to reduce their uncertainty through argumentation on why the kidney beans did not germinate. Second, students used elaboration-oriented rebuttals, personal opinion-oriented rebuttals, and blame-oriented rebuttals to reduce this uncertainty. However, when they used blame-oriented rebuttals, their uncertainty and negative emotions increased. Third, intervention by the teacher led students to stop using blame-oriented rebuttals. Instead, they employed elaboration-oriented rebuttals to explore why the kidney beans would not sprout, and finally, they escaped uncertainty by discovering an appropriate explanation. Based on the findings of this study, the researcher discussed how the interaction between uncertainty and elaboration-oriented rebuttals could shape and facilitate argument development in elementary school students.

Diamond thin films were synthesized by a chemical vapor deposition (CVD). Raman spectrum showed the diamond line at 1332 $cm^{-1}$ / and x-ray diffraction pattern exhibited a strong (111) peak of diamond. The scanning electron microscopy analysis showed that the CVD diamond thin film was grown to be unepitaxial crystallites with pyramidal hillocks. A wavelength-resolved thermoluminescence (TL) of the CVD diamond thin film irradiated with X-rays showed one peak at 430 nm around 560 K. The glow curve of the CVD diamond thin film produced one dominant 560-K peak that was caused by first-order kinetics. Its activation energy and the escape frequency were calculated to be 0.92 ~ 1.05 eV and 1.34 $\times$ 10$^{7}$ sec$^{-1}$ , respectively. The emission spectrum at 560 K was split into 1.63-eV, 2.60-eV, and 3.07-eV emission bands which is known to be attribute to silicon-vacancy center, A center, and H3 center, respectively.
