The goal of this study was to estimate the possible scattering distance of deicer from the highway and the impact range of deicer on soil quality in terms of plant growth. Among the major elements (Ca²⁺, Cl^- and Na⁺) of deicer, Ca²⁺and Cl^- are usually applied as fertilizer to soil. Therefore both elements (Ca²⁺and Cl^-) were not appropriate for a tracer of deicer at the agricultural area. In this study, SAR (sodium adsorption ratio) of soil was proposed as an alternative tracer to confirm the distribution of the deicer around the highway areas. Because deicer is the main anthropogenic source of Na⁺ around the highway areas and does harm to the physical properties of soil and plant growth through the destruction of soil aggregate, SAR would be an recommendable tracer to access the distribution of deicer as well as adverse effect on soil quality at highway areas. The influence range of deicer based on SAR of soil was estimated to be less than 20 m distance from the highway even though the possible flying distance of deicer was found to be more than 100 m from the highway. However the deicer seriously deposited within 10 m from the highway.

Adolescent volunteer, a kind of experience activity, can have positive influence on the improvements of sound personality, community ownership, and leadership living skill ability. However, its purpose is today declining because it tends to be only used for the adolescent university admission. This study investigates the impacts of adolescents' volunteer participation motivation(selfish and selfless) on leadership living skill ability(human relationship skill, group activity skill, learning skill, and self-understanding skill) and satisfaction. The study conducted a survey and utilized 222 questionnaires to examine these relationships. The results are as follows. First, selfless participation motivation had significant impacts on four leadership living skill abilities and satisfaction. Second, selfish participation motivation had no significance on four leadership living skill abilities, but had negative significance on satisfaction.

The bearing wall apartments which occupy the majority of multi-residential apartment buildings built in Korea, are known for having limited architectural plan flexibility, posing challenges in terms of maintenance and remodeling. The economic losses and environmental issues resulting from the reconstruction of bearing wall apartments are now accumulating to the extent that they are becoming a national concern. Multi-residential apartment buildings, which are now the dominant form of residence in Korea, must accommodate diverse customer needs and changes in life style. A new concept of Rahmen structure with architectural flexibility is Green Frame. GF multi-residence housing is expected to reduce construction costs and shorten the construction schedule by overcoming the shortcomings of conventional bearing wall apartments. This goal is consistent with the national policies that target the reduction of resource and energy consumption. In addition, GF will be established as a core contributor to achieving a reduction in $CO_2$ emissions, which will enable the sustainable growth of domestic construction industry, and address the low-carbon green growth drive implemented by the government.

네트워크의 발달로 인하여 지역적으로 원거리에 위치한 다수의 사용자들이 공동 작업을 수행할 수 있는 다양한 기술들이 개발되었다. 공동작업을 지원하는 협업시스템은 HTTP 프로토콜을 사용하거나 또는 각자의 고유한 통신 프로토콜들을 정의하여 구현하였다. 이러한 방법은 협업시스템 간의 상호 운용성이 결여되는 문제를 발생시켰다. W3C의 IETF에서는 협업지원을 위한 WebDAV 명세가 발표되었다. WebDAV는 웹상의 공동 저작활동을 지원하기 위한 표준프로콜로서, 원거리에 있는 사용자들 간에 인터넷상의 파일을 편집하고 관리할 수 있도록 해주는 HTTP의 확장이다. 이를 이용하여 협업시스템을 구성하면 협업시스템 간의 상호 운용성을 높일 수 있을 것이 다. 협업시스템의 클라이언트는 협업지원 서버의 자원들을 효율적으로 이용할 수하고 팀원들 간의 상호작용이 원활 하게 이루어 져야한다. 이러한 요구 조건을 고려하여 본 논문에서는 WebDAV 프로토콜을 이용한 협업시스템의 클라이언트를 설계하였다. 고급기능으로 사용자가 협업지원 서버의 파일을 편집할 때 자동으로 저작프로그램을 연결하고 저작프로그램을 종료할 때 파일의 변화된 내용과 파일의 버전관리를 실시간으로 서버에 적용될 수 있게 디자인하였다. 또한 드래그앤드롭(Drag & Drop)을 통한 파일이동을 지원하고 파일의 읽기모드와 쓰기모드를 지원하는 기능을 설계하였다.

In suite of a high supply of multi-family housings, the government's housing policies have only been focusing on the construction of housings and their supply, while being almost indifferent to the maintenance management of them. As a result, a considerable amount of inconvenience to the use of housing resources and habitation of residents occurred. Accordingly, on this paper, the current housing policies and their inspections on the maintenance period are compared and analyzed with suggestions for improvement. Analysis shows that repairing of housings at appropriate time not only significantly delays the deterioration of housings, but also keeps the function of housings to their original condition. Therefore, through an efficient management of repair maintenance, wearing of buildings can be delayed and their functions can be improved.
