Related to the situation on the Korean Peninsula, by North Korea's threat of war the tension escalates and serious crisis continues. The purpose of this study is to evaluate the subjective perception which the residents of South Korea feel about North Korea's threat of war through a Q methodological analysis framework. In the result of the study, for the North Korea's threat of war the South Korean's recognition type is analyzed into four type such as 'non-reactive', 'fearreactive', 'psychological anxiety' and 'cynical ignorance type'. First, the No. 1 type 'non-reactive' does not empathize with North Korea's threat of war itself, and second type 'fear-reactive' have uneasy feeling like that 'What would happen as things go' and feel a sense of crisis about the North Korea's threat of war. The third type 'psychological anxiety' is type which feels that due to North Korea's threat of war inter-Korean relations is in the crisis. Finally the fourth type 'cynical ignorance' think that North Korea's threat of war is bluffing and also North Korea is like a shepherd boy. The reason to apply Q-methodology in this study is to make it possible to a more in-depth approach to subjective perception and threat of psychological meaning for the threatening message of study participants.

There have been numerous researches on Nak-An village in Jeollanamdo, one of the most representative traditional castle village in Korea. Most of them have dealt with general and physical architectural scale and features separately. Therefore this study aims to understand the compositional characteristics of building layout and exterior space and the relations between street system and dwelling unit of folk houses in Nak-An village. The study examined houses of ordinary people in Nak-An village constructed before the village was not affected by foreign influences. 36 folk houses in Nak-An built from nineteenth century to early twentieth century and believed to have few physical changes from the original floor plans and architectural forms were the subjects to be analyzed. The most popular types in building layout are "Open L"and "Open U". The most typical orientation of main building is Southwest. The favorable entry into the dwelling lot is from the side. The street system in the village consists of main streets of South-North, resulting in dwelling lots with North-South axis most general. This site condition forces the entry into the lot from North main street and the side access to the main building. From these findings, the building layout and the entry into the dwelling lot of folk houses in Nak-An are strongly related with street system and conditions of dwelling lot.

This study was carried out from June 1996 to November 1997 to analyze the growth characteristics of the introduced species revegetated on highway cut-slopes. The number of revegetation measures type surveyed were fourteen such as seed-spraying measures, block-sod pitching measures, and hydro-seeding measures with seed-fertilizer-soil materials. The introduced species for revegetation measures were mostly Festuca arundinancea(cool season grass), Eragrostic curvula(warm season grass), Lolium perenne(cool season grass), Dactylis glomerata(cool season grass), Poa pratensia(cool season grass). The species diversity index of the upper part on highway cut-slopes were greater than that of the middle part and lower part. The growth of introduced species was good on north-facing cut-slope than the others and that was flourish in temperate north forest zone. Also, the introduced species seemed to decrease or disappear, while the ratio of native woody and herb species which were in mature stage seemed to increase.

This paper deals with "Citizens Organization" and "Citizen Participation" to the process of the regional planning and design not only in urban areas but also in rural residential areas with regard to the range of topics, such as its planning, partnership, environmental study, exchange, training of talented persons and NPO. Even though many attempts on this issue have been developed in various part of Japan, I examine in this essay especially the case of citizens in Hyogo Prefecture. As regards a case in urban areas the various movements set after Great Hanshin and Awaji Earthquake are introduced. As a case in rural residential areas with abundant nature, the activities of "Tamba-no-Mori"in Tamba District and a concept for "the Idyllic Landscape Museum" in North Harima district are introduced.

This study is to propose guidelines on waterfront landscape planning for Busan North Port redevelopment area. In Korea, Busan North Port redevelopment project is the first one which aims to make old port area into citizen-friendly waterfront. It is expected that many ports will be redeveloped soon after this urban waterfront remaking project. This is the basic research to lay groundwork for waterfront landscape planning at port redevelopment area. We analyze good examples of genera/landscape plans for port redevelopment area through case studies and suggest the problems and important elements for making landscape plan of Busan North Port area. Also we propose guidelines for making waterfront landscape plan of the redevelopment area at Busan North Port.

This study analyzed on the developmental process of forest policy direction in Korea and present status of forest desolation in North Korea of the pre and post division of the Korean peninsular with historical point of view and indicates future tasks to take. Forests in Korea were destroyed in the early of 1900s while Korean peninsular was under Japanese colonial rule. In 1945, Korea was divided into two parts, which developed its own forest policy under the different political system. South Korea was at Korean war in 1950 and accomplished the greening movement from 1970s to 1980s. After 1990s, the country has aimed to sustainable forest management. North Korea has focused on forestation until 1960. However, the result has been doubtful with North Korean economic depression, and these days North Korea faces forest desolation due to failures of forest management. Therefore, necessary is that recovery measures for forest desolation in North Korea, cooperation and interchange between North and South Korea and plans of forest management in case of unification.

This paper interprets the social and cultural significance of the "landscape" in North Korea by exploring the object and context of the text referring to the "landscape" in North Korean literature. To this end, the paper first classified the objects describing "landscapes" in serial publications and newspaper articles by types and grouped them according to trend. As a result, the social and cultural significance of the "landscape" in North Korea can be divided among "Projection Object of Orthodoxy", "Visuality extended to the City" and "Visible Socialist-Fairyland". First, in an article about Baekdusan (Mt. Baekdu), "landscape" was used as a medium to prove the legitimacy of the successor. Next, in the Kim Jong-Un regime, "landscape" was used as a word to describe the visual interactions by human economic activities. Finally, as a way to visualize the achievements in the landscape sector, a term for ranking landscapes such as "Socialist-Fairyland" was adopted during Kim Jong-Un's reign. This can be interpreted as one of the devices visualizing the "landscape" and is clearly distinguished from the past.

This study has been carried out to classify forest vegetation in south and north slopes of Donghaksa valley for supplying basic data for conservation and restoration of the valley. With the phytosociological method, the forest of the south and north slopes of Donghaksa valley was classified as four groups; Quercus variabilis community, Quercus mongolica community, Pinus densiflora community and Carpinus laxiflora community. The dominant species were found in the order of Pinus densiflora, Quercus variabilis, Carpinus laxiflora, and Quercus mongolica. Comparing the north and south slopes, Quercus variabilis were the highest dominant species in the south and Carpinus laxiflora in the north. Pinus densiflora were the next dominant species in both south and north slopes. According to the DBH analysis result, Pinus densiflora and Quercus variabilis had density of normal distribution style among the entire community. Therefore, their dominance are expected to continue for now. But, Quercus mongolica and Carpinus laxiflora are expected to extend their influence in the future in terms of competition with Pinus densiflora. The correlation between each community and the environment according to DCCA ordination was examined in this study. The result told us that Quercus variabilis is distributed mainly on the south slope in a mid-steep and mid-altitude area. Quercus mongolica community appeared on the north slope in the steep high-altitude area that has high percentage in total nitrogen and CEC. Pinus densiflora community is distributed on both south and north slopes in a gentle slope and low-altitude area. Carpinus laxiflora is distributed on the north slope in a mid-steep and mid-altitude area.

Cyber powers around the world are conducting cyber information-gathering activities in cyberspace, a global domain within the Internet-based information environment. Accordingly, it is imperative to obtain the latest information through the cyber intelligence preparation of the battlefield (IPB) process to prepare for future cyber operations. Research utilizing the cyber battlefield visualization method for effective cyber IPB and situation awareness aims to minimize uncertainty in the cyber battlefield and enable command control and determination by commanders. This paper designed architecture by classifying cyberspace into a physical, logical network layer and cyber persona layer to visualize the cyber battlefield using BGP archive data, which is comprised of BGP connection information data of routers around the world. To implement the architecture, BGP archive data was analyzed and pre-processed, and cyberspace was implemented in the form of a Di-Graph. Information products that can be obtained through visualization were classified for each layer of the cyberspace, and a visualization method was proposed for performing cyber IPB. Through this, we analyzed actual North Korea's BGP and OSINT data to implement North Korea's cyber battlefield centered on the Internet network in the form of a prototype. In the future, we will implement a prototype architecture based on Elastic Stack.
