In this study, a risk-based cleanup approach using the leaching potential was suggested for the soil vapor extraction (SVE) process. A multi-component model was adopted with local equilibrium assumption (LEA), and Raoult's law was applied to estimate the leaching potential for BTEX. Finally, a risk analysis was conducted based on the leaching pontential calculated. To complete the feasibility of this approach, more investigations and discussions will be required in future.

Optimal Mullite sol was synthesized by sol-gel process using Aluminium sec-butoxide(ASB), Tetraethoxysilane(TEOS) and then, Mullite films were dip-coated with various holding time in sol bath and heat-treated at 130$0^{\circ}C$ above for crystallization. The thickness of coated film increased linearly with holding time in sol bath and average pore size was controllable within 20~30$\AA$.

최적의 사 균제도를 갖는 방적사를 제조하기 위해서는 슬라이버나 조사와 같은 섬유집합체가 어떤 일정 수준의 섬유응집력 및 드래프트 특성을 가져야 하는 것으로 알려져 있다. 드래프트 힘이 어느 정도 올라가면 정적마찰력을 극복한 가속된 섬유와 아직 가속되지 않은 섬유간의 상태가 계속해서 변화하게 되는데, 이와 같이 정적상태에서 동적상태로 전환됨에 따라 사 균제도에도 그에 상응하는 영향을 미치게 된다. (중략)

Anti-infammatory, analgesic and ulcerogenic activities of fentiazac were investigated in comparison with those of acetylsalicylic acid, fenbufen, naproxen and phenylbutazone. On the anti-inflammatory activity in carrageenin-induced rat paw edema and the analgesic activity on writhing syndrome induced with acetic acid in mice, fentiazac displayed more potent effect than acetylsalicylic acid, fenbufen and pbenylbutazone. But the ulcerogenic action of fentiazac on gastrointestinal tract in fasting rats was less than that of reference drugs. From these investigation, fentiazac seemed to indicate a poor correlation between the extent of anti-inflammatory activity and ulcerogenic action.

To determine in vitro effects of phenylbutazone and niflumic acid on warfarin binding to rabbit serum protein, warfarin was added to the rabbit plasma, and the bound fraction was determined by warfarin-protein complex fluorescence. The bound fraction was decreased by phenylbtazone and niflumic acid. From this effect niflumic acid was found to have the more potent ability to displace warfarin from protein binding sites than phenylbutazone.

Adamantinoma is a rare malignant tumor and approximately 85% of cases occur in the tibia. In 1985, Moon and Mori reviewed the world literature and identified 195 cases. A 59-year-old woman was presented with nonspecific pain on left leg after trauma. Radiographic finding showed well-circumscribed soap bubble appearance with areas of sclerosis in diaphyseal region of the tibia. Magnetic resonance imaging and biopsy was performed for diagnosis. Histologically, the lesion was compatible with adamantinoma. Wide resection with bone graft was performed. There was no recurrence at 3 years follow-up. We report a case of adimantinoma that arose in diaphyseal region of the tibia with review of literature.

We will introduce a method of construction of super-block curtain wall applied to Tower Palace III which is the highest high-rise complex building in Korea. Up-up method is utilized on Tower Palace III to shorten the term of works and it is that the curtain walls for the belt wall part are installed after the rests. The belt wall structure increases the horizontal structural stiffness of the building. The method of construction of super-block curtain wall is developed and used to raise and install the curtain wails of the belt wall floor. It is that the large block of curtain walls corresponding to three stories is fabricated on the ground in advance and the block is installed at a time by a tower crane. Specialized installing equipment :,s newly developed and applied to install the super-block. curtain wail. The curtain wall of the upper floor of the belt wall part is installed after the super-block. The installing equipment for this floor is developed utilizing a mini excavator and vacuum suctions. The application of this method had made it possible to omit the setting up the scaffold and financial profits such as the shortening of the terms of works was realized. The safety of works was secured and the productivity was also improved.

In this study, the concept of Just-In-Time, Lean Construction and Supply Chain Management have been applied to furniture works of high-rise residental building. For the purpose of systematic furniture work planning, it should be established to analyse furniture-work process from design phase through contract, and procurement to construction phase. The analysis of process and data for furniture-work provides the roles of conducting subjects and presents management items at each phase. This proposal will provide the systematic furniture-work managements and reduce construction time and cost, and also raise the quality of furniture works.

Poor expertise in equipment operation and installation, coupled with unpredictable natural disaster, usually directly leads to disastrous accidents of large lifting equipment such as tower cranes. For example, 52 tower cranes fell down due to the unstable support in Korea at the attack of Typhoon "Maemi" in 2003, which damaged property and caused loss of life. In high-rise construction projects, top-slewing or luffing-jib tower cranes needs checking the stability of lateral-support in addition to the bottom support such as the foundation. In this study, the optimization algorithm for lateral-support of tower cranes is conducted, which is expected to enhance the structural stability of tower cranes and save the cost in conflict with the safety.

A construction temporary work is main process and importance trade section. It has many works and facilities such as temporary transfer equipments which tower crane, and lift, and architectural temporary facilities which temporary office, temporary warehouse, and site test laboratory, and construction temporary equipments which scaffoldings, work plates, construction supports, and forms to set and to use in under construction and to remove in the end. A technology system of construction temporary has very low availability of field works and needs improvements in Korea as construction site has a quick response about new requirements. This study is organized existing technology systems and new technologies for field works, and developed breakdown structure of construction temporary technologies to be a basic of temporary technologies as review with site managers. For this, it will improve to be a knowledge and information system as a research of a performance and an availability about a construction temporary technology index.
