The risk management is an organized method for identifying and measuring risk and for selecting, developing, and implementing options for the handling of risk. The risk management covers all programatic and technical factors which affect the system development performance, cost, and schedule. While technical issues are primary concern for systems engineering, the three elements(performance, cost, and schedule) must be balanced for a successful risk management process. This paper proposes the risk management process for the KSLV-I(Korea Space Launch Vehicle-I) program using computer-aided systems engineering tool, Cradle. The risk management process of KSLV-I program is similar to the general risk management process, but it has its own specific features to manage large-scale complex characteristics of KSLV-I program.

The purpose of this study is examine the characteristics of public open space in the office buildings located in urban commercial strip, in terms of its relationships to street, to building, and to order surrounding facilities. Theoretical basis of this research is that public outdoor spaces are to be the intermediate territory set between streets and a buildings. 5 commercial buildings in Seoul are selected as sample cases and they were closely analyzed in a comparative manner. Based on this comparison, several planning guidelines are suggested for the activation of the space, mainly in terms of the location of public open space in relation to street, the design techniques and devises reflecting the purpose of the space, and territorial arrangement and furniture layout, and the patterns of relationship to surrounding space and facilities.

The Changing Characteristics of Office Location in Central Seoul In recent years, central Seoul has been experiencing a dynamic transformation. In the process of reorganization of urban industrial structure including tertiarization and quaternarization of the economic base of Seoul, business services are growing very rapidly and large scale urban renewal projects are agilely implemented. Downtown office activities become a nucleus for economic performance of Seoul and high-rise office buildings steer the landscape transformation of central Seoul. Even though there appear to exist some evidences that office districts have dispersed to several subcenters, major office activities are still concentrated in the central Seoul. This paper redefines office industry in a narrow meaning comprising only relevant economic sectors and office buildings as office activity-functioning units. It then explores the industrial networking and territorial specialization of office activities focusing on the dual process of concentration and dispersion in Seoul. The changing characteristics of the downtown linkages of office activities in this post-industrial era transforms the spatial economy of central Seoul into more flexible and volatile, while territorial concentration of power and control functions are fortified at the same time. Finally, the paper addresses the development of manufacturing-tertiary-quaternary industrial complex, which can be regarded as new industrial clusters, selling cultural economy of urban space and possessing placeness or images for clients and customers, in relation to urban competitiveness and territorial specialization of large metropolitan areas.

After the period of the Three Kingdoms Korean transportation architecture had been changed from the characteristics of the administration organization supporting the kings ruling system and gradually the characteristics as transportation architecture had cleared and diversified in accordance with the functions and characteristics of it. With this it was found that Korean transportation architecture like YukSa(驛舍), ChamYuk(站驛), GaekSa(客舍), JinSa(津舍), DoSa(渡舍), WonWoo(院字), JuMak(酒幕) and etc. had been developed variously and the architectural characteristics had developed with the functions and characteristics of transportation architecture. Some of them ,for example YukSa, ChamYuk, GaekSa, JinSa, DoSa, had the characteristics of the government office, so they had fundamental dignity of Korean wooden architecture on tile roof. But the WonWoo which was used by all of the people from the king to the people, had the characteristics of half-government and half-private. And the space of WonWoo was divided by the social position, the sex and the difference of temperature between summer and winter. And it was mostly located at the place away from the haunts of men, the form of it was the mud wall hut of the straw-thatched cottage like Sinhyewon of Mungyungsaejae and it was different from the station building of the characteristics of government office.

This study was conducted to analyze the planting structure and ecological characteristics of greon spaces on the grounds of e Dangjin steam power plant. To achieve these goals, we surveyed existing vegetation, plant community structure, Plant volume and growth rate. Based on e vegetation analysis, existing vegetation was classified into six types: herbaceous species $(70.54\%)$, evergreen coniferous trees $(21.17\%)$, deciduous broad-leaved trees $(5.10\%)$, deciduous coniferous trees $(1.47\%)$, shrubs $(0.12\%)$, and other types $(1.59\%)$. The coal storage, office, and playground areas were community is the natural forest area where a Pinus thunbergii / Pinus densiflora community is distributed in terms of vegetation structure, species diversity, plant volume, and growth rate. The artificial green spaces(near the coal storage, office, playground areas) had a single-layer structure. Species diversity indices of the artificial green areas were $0.1655\~0.4807$ compared to 0.8628 in the natural forest, which presented a good growth environment. Also, the plant volume in the artificial green space was lower than that of the natural green space. Therefore, it would be desirable to develope a multi-layer structure similar to that of the vegetation in the natural green space in order to improve the amount of plant volume. The plant-damage ratio of Pinus thunbergii was $52.48\%$ in the coal storage area, and $8.48\~ 11.52\%$, in the other survey areas. Also, the vitality of Pinus thunbergii was $15.45k{\Omega}$ in the coal storage areas, which indicates bad growing conditions. This suggests that soil characteristics and dust have a bad impact on growth. The investigation into deciduous tres' growth status showed that appropriate plants would be Albizzia julibrissin, Acer palmatum var. sanguineum, Acer palmatum, Malus spp., Prunus sargentii.

In today's knowledge economy, various schemes are being devised in order to attain knowledge and understanding in the most effective ways possible. In an office environment, spatial concepts that encourage 'smart working' is becoming more prevalent; therefore allocating of space according to the types of work being performed, ways to maximise the work efficiency, and furniture arrangement to accelerate liaison among the users are being carefully considered. Especially in a space where its members are encouraged to communicate and collaborate, the furniture within that space need to be attractive and practical for its users, as well as efficient and effective for the firm the service is being provided for. In this study, we aim to offer furniture design service that satisfies such demands of the present time. Thus, instead of merely following a standard design process in which one approaches a project from design planes to an outcome, various aspects of the working environment will be considered such as the relationship between the space and the users, their needs, and the features of work being performed within the space. After attentive research and analysis, the results will be put into production from the user's point of view in mind. This study is intended to propose furniture design that embodies the characteristics of integrated working environment that can facilitate efficient use of the limited working space, productivity among the users, and promoting valuable corporate culture.

Transient luminous events (TLEs; sprites, elves, jets and etc.) are lightning-related optical flashes occurring above thunderstorms. Since the first discovery of sprites in 1989, scientists have learned a great deal about the morphological, spectroscopic and electromagnetic characteristics of TLEs through ground and spacecraft campaigns. However, most of the TLE studies were based on events recorded over US High Plains. To elucidate the possible biasing effects, space-borne observations are needed and have their merits. Imager of sprites and Upper Atmospheric Lightning (ISUAL) on the FORMOSAT-2 satellite is the first instrument to carry out a true global measurement of TLEs from a low- earth orbit. In this short paper, we apply a common astronomical data analysis technique, two-color diagram, on the ISUAL spectrophotometer (SP) data. By choosing appropriated bandpasses and converting the measured flux of TLEs into the unit of magnitude, two-color diagrams of TLEs can be constructed. We demonstrate that two-color diagrams, which were constructed from the narrow-band spectrophotometer data, can be used to classify different types of TLEs and trace their temporal evolution. The amount of reddening due to Earth's atmosphere can also be estimated from two-color diagrams assembled from the broad-band spectrophotometer data.

This research used Analytic Hierarchy Process(AHP) to analyze the importance and priority of functional space and evaluation factors of each functional space of the military dining facility. Dining in the military is an important factor in restoring combat power and promoting morale. The military dining facility serves as a not only for meals, but also for watching TV, education and club activities. Workers working in dining facility spend most of their work hours in dining facility, perform tasks such as cooking, dishwashing, and leftover disposal, and take breaks. As such, the military dining facility is a space where various functions are performed, and space planning should take into account these various functions when planning the building of the dining facility. However, the criteria for defense and military facilities, which are the basis for planning the space of military dining facility, are calculated only by simply analyzing the standard floor plan to match the size of the person-to. Therefore, when there is space to be reduced in the total area, there are side effects such as leaving visible table space without consideration for priority or functional space, unseen office space, and adjusting the entire area through reduction of the lounge. Accordingly, based on the priority of the space that the staff of the military dining facility considers important, this research aims to analyze the characteristics of each functional space through classification according to its unique function. This can be an indicator that can be used as a basis for future revision of the building floor area standards of the defense and military facilities standards, and it can improve usability with an efficient space plan that takes into account the characteristics of the Korean military and the satisfaction of its workers. Furthermore, efficient use of the defense budget through rational building plans can contribute to budget reduction.

The present study is a basic research for promoting the globalization of Korean food, aiming to analyze Japanese restaurants in Hong Kong, an international city successful in globalization, focused on their spatial characteristics and food related characteristics and to use the results as basic materials. The results of this study are as follows. As to the characteristics of indoor spaces and food of Japanese restaurants in Hong Kong, first, the locations of Japanese restaurants were mostly easily accessible luxury hotels, office buildings or shopping malls. They displayed Japanese styles well and used conspicuous signs. Their trade names were given after traditional place names, food names, greetings, etc. Second, the spaces of Japanese restaurants expressed contemporary and, at the same time, traditional styles moderately and elegantly by applying emphatic articles such as traditional furniture, tools and folk paintings to contemporary spaces with traditional air, and by doing so, they showed various possibilities. Third, as to the characteristics of food culture, menus were diversified from traditional menus such as kaiseki to everyday menus such as vinegared rice, ramen, skewered roast meat and fusion dish, and at the same time, differentiated by concept. In addition, some restaurants succeeded in globalization and modernization with chains throughout the world. Furthermore, while table setting, food dishing and tableware image were harmonized with the concept of the restaurant space, if tradition needed to be displayed it was used at a minimum, showing the Japanese aesthetic sense through the restaurant space and food. In globalizing Korean restaurants based on the results of this study, we need to link trade name, facade, sign, menu and space with served food, and to plan a consistent story so that Korean culture and images are expressed. In addition, if a manual is made by benchmarking the Japanese government's support policies and relevant businesses' efforts and ideas and provided to Korean restaurants, it will be helpful for Korean restaurants, which spread Korean food culture, to be more competitive and graceful.
