The recognitions of geometrical characteristics and occurrence conditions are very important to evaluate the land-slides in natural terrains. In this paper, the geometrical characteristics of landslides are analyzed according to a geo-logical condition in three landslides areas. The three landslides areas are classified to the geological condition. The three landslides areas are Jangheung, Sangju and Pohang. The geology of Jangheung area, Sangju area and Pohang area is gneiss, granite, and the tertiary sedimentary rock, respectively. During a heavy rainfall of $150{\sim}588mm$ in these areas, 1,582 landslides have occurred in 1998. The geometrical characteristics according to the geological condition analyzed from the investigation of these landslides. The frequency of landslide is high exceedingly above 90% of a slope attitude, while the frequency is very low below 70%. The frequency of landslide is high exceedingly between $26^{\circ}$ and $30^{\circ}$ of slope angle, while the frequency is very low below $20^{\circ}$. The size of the landslides is ranged from several tens to several hundreds The length is ranged from 5 m to 300 m, and the width is ranged from 3 m to 50 m. Also, the depth is less than 1 m. Therefore, the landslides in these areas have small width, long length and shallow depth. The type of the landslides is changed from transitional slide at the scarp to debris flow at the low part of slope.

As the capital of knowledge becomes more important than traditional capital like land or labor in the 21st century, the most competitive resource for corporations is knowledge. Furthermore, corporations may evaluate and improve latent knowledge of 'intellectual capital(IC)' within organizations, which will enhance their performance in the future. However, most Korea Distribution Companies have evaluated only tangible assets, ignoring latent capital. Since enterpreneurs have recognized that they cannot explain the difference between maret value and book value, the major advanced states lead to more sophisticated techniques to evaluate IC value. Although it is extremely important and urgent to evaluate IC value, the indexes of evaluating IC have never been examined and have been adopted by many corporations. Therfore, this study intends to develop a index for IC valuation. This study hopes to give some insights into the practical use of intellectual capital for the Korea Distribution Companies and help them develop a strategic perspective to enhance their competitiveness.

The character is not dependent on an original story world any more. It is not limited to it's own story, but gets out and expands the other story with new character, background story, and event regardless of genre and media. The purpose of this study is to analyze why should this phenomenon happen from the media perspective and to build a character storytelling model through the specific examples. With the advent of the digital paradigm the storytelling model is emphasized character storytelling. Character is no longer limited to just one narrative and extended beyond the boundary narrative, media and genre. There are four background. First, disappearance of the big story with the advent of postmodernism and the emergnece of small story. Second, the emergence of fandom culture and charater's liberalization. Third, character as public goods with database. Fourth, changes in author's position. In fact, in the traditional narrative theory there has been discussion about the character all the time. But character storytelling meets transmedia storytelling, discussions were accelerated. The character was preceded by a narrative independent existence. Even if that character has occurred even while leading cause narrative. In this paper, we suggest two model as specific methodology to expand the story world fixed character. One is phychology transition, another is roll transition. This study get the value to build the new storytelling model with digital paradigm.

This Research is focused on ancient battle formation basing on the layout drawing of Yijinchongbang (manuals of learning military formations) in a strategy book in the late Joseon dynasty. The research topic is the principles of organic composition of battle formation and battlefield operating system by reforming the basic model of ancient battle formation. The research method is comparative analysis by reforming the battlefield operating system of types of disposition such as Obangjindisposition(Bangnjin; battle formation, Jikjin; direct battle formation, Gokjin; bend battle formation, Wonjin; round battle formation, and Yejin; keen battle formation), and Hyunmoojindo; turtle battle formation, Paljindo; all-rounder battle formation, Yookhwajindo; six flowers battle formation, Gugunjindo; nine forms battle formation. From the study results, Standoff Bombing of the battle formation in the late Joseon Dynasty basically started out from magic battle formation, but was then transformed into square, rectangle, pentagon, and circle. Also, the battle array composition used a 5-linear structure and was composed of 5 systems of circulation such as rectangle, square, diagonal, curve, and circle. The research findings elucidate the battlefield of the Joseon dynasty by establishing the real battle formation, and thus have military and academic value in suggesting possible tactics that can be used by modern training of military.

Generally, inappropriate driving conditions including geometric, traffic environmental, and driver psychological problems may be critical reasons of traffic accidents. Under this circumstance, various types of facilities have been installed to improve traffic safety by itself or as a set consisting of several other traffic safety facilities. In general, traffic accidents occur by several reasons combined rather than only a single reason, and thus the safety effect of the safety facilities cannot be simply analyzed with only a single improvement. For the study, traffic accident data on the roadway segments of interest are collected along with field survey data. For the analysis, various alternative analysis methods were evaluated in terms of assessing accident reduction from various types of traffic safety improvements. Among the alternative methods tested including simple before-and-after evaluation method, before-and-after evaluation yoked comparison, and Comparison Group (C-G) method, it was found that the C-G method is the most effective method for analyzing the traffic safety improvement effect. Adopting the C-G method, both single and multiple safety improvements were analyzed. The results from this study can potentially be applied to decide the best type of treatments to improve traffic safety as well as to measure the accident reduction effects from the treatments.

Facing reconfiguration of world economic order in the process of globalization and changes in domestic economic and social conditions, Japan has experienced a rapid inflow of foreign immigrants and hence a restructuring of labor market and ethic and cultural mixture. This paper explores contexts of inflow and social and spatial characteristics of immigrant workers in Japan. Uneven regional development on the global level and shifting to flexible accumulation regime, depletion of previously underutilized labor resource, better-educated youth and shrinking and aging of Japanese populace on the national level can be pointed out as important elements of immigration contexts. This paper also explains the hierarchizaton of labor market and differentiation of spatial distribution of immigrant workers in Japan in terms of visa condition and nationality. In particular, focusing on the case of Hiroshima prefecture, this paper analyzes residential differentiation of immigrants according to their nationality. Finally, it finds out some problems which immigrant workers have confronted in Hiroshima region.

This study discussed characteristics of Shindu Coastal Dune as habitat, and relationship between geodiversity and biodiversity. It was identified spatio-temporal variation of incoming nutrients depended on geomorphic differences of foredunes. The main incoming path of nutrients into coastal dune was considered as influx with movement of wind blown sands from the beach and tidal f lat. Concentrations of Na, Mg, K, Ca, and P in blown sands were compared. Concentrations of Na, Mg, and K showed high and irregular pattern in favorable condition of influx of blown sand. So these nutrients were related with geomorphic characteristics of foredunes. However, Na was also influenced by other factor such as salt spray. P was independent from effects of sea water and blown sands. In the case of Ca, a large coastal dune system rather than localized forms of foredunes made differences in the variation. Due to differences in spatio-temporal variation of nutrients, patterns of major vegetation could be inferred to appear differently. This study shows geomorphic dynamics of coastal dunes as habitat, and will provide information for coastal dune management and for understanding biological distribution and growth pattern in coastal dune.

Malicious codes have been widely documented and detected in information security breach occurrences of Microsoft Windows platform. Legacy information security systems are particularly vulnerable to breaches, due to Window kernel-based malicious codes, that penetrate existing protection and remain undetected. To date there has not been enough quality study into and information sharing about Windows kernel and inner code mechanisms, and this is the core reason for the success of these codes into entering systems and remaining undetected. This paper focus on classification and formalization of type target and mechanism of various Windows kernel-based attacks, and will present suggestions for effective response methodologies in the categories of, "Kernel memory protection", "Process & driver protection" and "File system & registry protection". An effective Windows kernel protection system will be presented through the collection and analysis of Windows kernel and inside mechanisms, and through suggestions for the implementation methodologies of unreleased and new Windows kernel protection skill. Results presented in this paper will explain that the suggested system be highly effective and has more accurate for intrusion detection ratios, then the current legacy security systems (i.e., virus vaccines and Windows IPS, etc) intrusion detection ratios. So, It is expected that the suggested system provides a good solution to prevent IT infrastructure from complicated and intelligent Windows kernel attacks.
