Floating architecture is the most effective way to accommodate itself to sea-level rise due to climate change. At the same time floating architecture is the best model to offer the new spatial experience through water-friendly environment. Domestic floating architecture is still on the early stage compared to Europe which has several companies specialized in designing and building floating architecture. Floating architecture is divided into 8 types according to its criteria such as program, form, scale, level, location, access, mobility and energy. The following are design characteristics of floating architecture : (1) composed of 2 stories, (2) having large deck, (3) designing rectangular plan and balanced mass, (4) maximizing view, (5) having water-friendly space, (6) multi-using space and minimizing surface, (7) planning section to control light reflecting from the water, (8) modular and unit system.

The Korean government concentrates on supplying public transit facilities for the mobility handicapped. In other hands, increasing needs of transfer information when the mobility handicapped use transit facilities are substantial but not satisfactory as a whole. This study focuses on evaluating the applicability of developed K-path algorithm to provide user-customized route information that could make an active using of public transit while considering the mobility handicapped preferences. Developed algorithm reflects on requirements considering transfer attributes of the mobility handicapped. Trip attributes of the handicapped are addressed distinguished from handicapped types such as transfer walking time, transfer ratio, facility preferences and etc. This study examines the verification and application of the proposed algorithm that searches the least time K-paths by testing on actual subway networks in Seoul metropolitan areas. It is shown that the K-path algorithm is good enough to provide paths that meet the needs of the mobility handicapped and to be adoptable for the future expansion.

This article analyzed the recent Korean accessibility standard supporting the people with disabilities. This is the basic study to make the interior environment more comprehensible and safer for the physically handicapped. Researcher selected the interior elements related to the mobility and accessibility for the physically handicapped. Then the '98 Korean accessibility standard code called 'Pyunui Chungjin Pup' were compared with the previous Korean building code and two other guidelines for evaluations. Result showed that 'Pyunui Chungjin Pup' addressed more obligatory items in facilities used by people with disabilities. That contributed to develope the accessible environments and to offer the independent activity in the society for the disabilities. However dimensions of 'Pyunui Chungjin Pup' showed the minimum standard. Also it did not provide the sufficient design considerations to make up the sufficient design considerations to make up the other types of disabilities including sensory limitations, or cognitive function limitations. Hereafter, the quality of accessibility guideline should be raised with further study.

The purpose of this study is to examine the features of students moving to other areas for university education in entrance stage. 2018 K-NSSE data were analyzed, and Chi-square test and binary logistic regression analysis were performed. As a result, many students in Seoul area moved to various areas, but students from local areas moved to Seoul area universities with low percentage. In addition, it was confirmed that there was a difference in socioeconomic background, high school type and academic achievement level, career maturity, and university commitment level among the students group moving from Seoul to the local and from the local to Seoul area. This study suggests that the government needs to provide systematic support to overcome the stratification structure of the university centered on Seoul and to secure diversity of student composition to improve the quality of education and contribute to regional development.

Recently, as the construction industry trend is changed to the market orientation which focuses on the autonomy and competition, the most construction companies try to adapt the new environment. Thus, this study analyzes the correlations of business strategy and core competency taken by the construction company to survive from the rapidly changing environment between the growth rate and rate of return of the company. Throughout the existing researches and theoretical studies, a business strategy and core competency of the construction company is drawn, and based on this, this study surveyed 746 construction companies. The results of the survey showed that the business strategy has any relationship with growth rate and rate of return and the core competency of the construction company has no relationship with rate of return either, while the core competency shows the relationship with the growth rate. Thus, it is analyzed that the construction company which has higher growth rate also has the high core competency level.

Relics are life traces of ancestors, and they are good data for giving an idea about space locations of that period. This study classifies relics according to their type, and for each classified group metrical analysis is carried out using GIS and triangle diagram. The criteria used for analysis of relics' locations are elevation, road accessibility and water accessibility. The analysis results show that every relic has its own distribution characteristics according to the time and the type. This means high possibility of approaching a geographical focus on relics distribution and location. While historical period was taking over prehistorical, relics locations moved from the points of great usage water supply possibility to the points of great traffic accessibility. Also, relics of the ruling class for each time period generally have good locations.

As the development as the IT society accelerates, the frequency of terrorism from malignant codes and other cyber crimes is increasing. Malignant codes show various forms of attack according to the intentions of the attacker, and leaves behind digital evidences, not analog evidences when damages occur. Digital forensic, the procedure of collecting and analyzing digital evidence is one of the main factors that must be carried out when damages from malignant codes arise. However, there are the difficulties of not being able to preserve the integrity and authenticity in the procedure of coping witht infringements, which must be maintained in the digital forensic procedure. To complement such problems, this paper suggests the method of applying forensic by identifying the malignant code infringement incidents according to the type of damages.

The aspects of typhoon-induced surges were classified into three types at the Western coast, and their characteristics were examined. The typhoons OLGA (9907) and KOMPASU (1007) were the representative steep types. As they pass close to the coasts with fast translation velocity, the time of maximum surge is unrelated to tidal phase. However, typhoons PRAPIROON (0012) and BOLAVEN (1215) were the representative mild types, which pass at a long distance to the coasts with slow translation velocity, and were characterized by having maximum surge time is near low tide. Meanwhile, typhoons MUIFA (1109) and WINNIE (9713) can be classified into mild types, but they do not show the characteristics of the mild type. Thus they are classified into propagative type, which are propagated from the outside. Analyzing the annual highest high water level data, the highest water level ever had been recorded when the WINNIE (9713) had attacked. At that time, severe astronomical tide condition overlapped modest surge. Therefore, if severe astronomical tide encounter severe surge in the future, tremendous water level may be formed with very small probability. However, considering that most of the huge typhoons are mild type, time of maximum surge tends to occur at low tide. In case of estimating the extreme water level by a numerical simulation, it is necessary not only to apply various tide conditions and accompanying tide-modulated surge, but also to scrutinize typhoon parameters such as translation velocity and so on.

This study classifies the types of urban railway stations that reflect the location characteristics of urban railway stations, the structure and form of station taxes, and the number of users, and the level of inconvenience in the transfer movement line for users by station type, the number and connectivity of transfer information, and the level of transfer convenience facilities. The number of installations, conflicts between users, and transfer information signs were analyzed. As a result of data analysis, it was found that the factors that cause the most inconvenience to urban rail users when transferring are the length and curvature of the transfer line, pedestrian density and number of passengers in the transfer passage, presence or absence of transportation convenience facilities, and the size and height of transfer information letters. These transfer inconveniences were objectified, quantified, and presented as evaluation indicators that can measure the transfer convenience of urban railway stations. Additionally, an evaluation scale was developed to measure the service level for each evaluation indicator. The evaluation scale for each indicator presented six levels by applying linear interpolation based on the maximum and minimum values of data derived through field surveys. However, it is judged that a comprehensive evaluation of transfer convenience that combines the importance and weight of each convenience evaluation indicator should be established through future research.

This paper identifies public transit-poors and derives spatial characteristics of the poors' distribution in an urban area by utilizing buffering analysis of geographic information systems and remote sensing techniques in the case of Daegu metropolitan city. Since special attention is given to elderlies, this study assigns three hundred meter buffer from bus/subway station as service boundary for elderlies. The results of this study tell us that 1) the transit-poors are concentrated on suburban and rural regions, 2) high proportions of the transit poors are elderlies with spatial variations in many regions, 3) the main housing type of the transit-poors is single detached house. We expect that this study can contribute to build an effective policy-making by showing essential technical processes and methods in identifying policy-need groups and their characteristics of spatial distribution.
