  • Despite of its advantange on shortening framework period of a super-tall building, gangform is prone to high safety risk due to its heavy weight during operation. Thus, this study is conducted to investigate the applicability of a lightweight gangform made of engineering composite materials. Compared to the conventional gangform, the proposed gangform showed greater performance not only in reduction of safety accidents on-site, but also in constructability and environmental aspects. The results of this study are expected to be served as the basis for developing the lightweight gangform in future.

  • This paper presents three methods for ship hull form improvement on the basis of wave pattern analysis. These methods are primarily based on the assumption that a linear relation exists between the small difference of hull sections and the difference of the wave amplitude functions. The improved hull form of ship is made by superposing a thin hull form on that of a parent model. The first method use the simplification of framelines and Michell's Theory to the formula of wave resistance for superposed thin ship. The second method use tent functions and Michell's Theory to that. And the third is experimental method.

  • 공사현장에서 사용하고있는 거푸집의 대체를 오랫동안 연구 끝에 가로(60cm) 세로(120cm)의 규격의 PE-FORM을 개발한바 있으나, 일반 건설 현장에서 어떠한 형태의 구조물 시공을 위한 형틀을 제작함에 있어 통상적으로 기존 합판거푸집을 사용하고 있으나, 현재 국내에서 사용되고 있는 합판은 전량 수입에 의존하고 있어 외화낭비가 심할 뿐 아니라 평균 2-3회 정도밖에 사용하지 못해 자원 낭비를 초래하고 있으며, 합판 거푸집을 사용한 경우, 목공이 구조물의 형태에 맞춰 FORM을 일일이 제작해야하므로 시간과 비용의 소모가 크고 또한 FRP-FORM, EURO-FORM, STEEL-FORM GANG-FORM SYSTEM-FORM 등 구조물의 성격 형태에 따라 각종 개량된 거푸집을 사용한다고 해도 그것은 단순한 구조물의 형상을 만들어 내기 위한 형틀로써만이 이용되고 있을 뿐, 그 이상의 목적으로는 활용 할 수 없기 때문에 구조물의 특성상 방수 방식의 기능이 요구될 경우, 거푸집 해체 후 벽체의 내부 또는 외부에 액체, 몰탈, 에폭시, 쉬트 방수등 별도의 후속 공정이 추가되 번거로움이 있는 반면, 그 효과는 기대에 크게 미치지 못하고 있는 점을 착안, 수년 전부터 연구에 착수, 콘크리트 구조체의 방수ㆍ방식 문제를 해결 할 수 있는 획기적인 공법의 PE-PANEL의 요철형 거푸집 및 방수ㆍ방식공법을 개발해내는데 성공함으로써 지금까지 난제로만 여겨졌던 목재 거푸집의 대체 자재개발과 아울러 거푸집 겸 콘크리트 표면의 마감 처리을 동시에 해결한 매우 혁신적인 신기술이라 할 수 있다.

  • Cheong-Gang Medical Chart is 60 years worth of diagnosis records kept by Oriental Medicine Doctor Kim Young Hoon [金永勳, 號 晴崗 1882-1974], who held practice in Seoul's Jong-ro from 1915 till 1974. Kim Young Hoon's eldest son, Kim Ki Su (金琦洙) donated the medical records exceeding a thousand volumes to KyungHee University, and researches are being made presently. The author of Cheong-Gang Medical Chart, Kim Young Hoon, was a medical scholar who studied the essence of the traditional medicine of his time. He was handed down the quintessence of traditional medicine by keeping in touch with the prominent oriental doctors in Seoul at that time, and he constantly applied it to his practice and made records of it. Consequently, his diagnosis charts contain a whole new form of prescriptions, treatment skills, and processes of clinical application that have never been seen before in the texts of Korean Medicine. The writer has written a paper on the present condition of Cheong-Gang Medical Chart, which was published in the Journal of Korean Oriental Medicine in 2004. This manuscript reports the results of the test studies made to develop an efficient database model as a prior step to organizing the medical records into a data bank.

  • Objectives : Jakyakgamcho decoction is a traditional prescription known to be an effective pain control medication and muscle relaxant. For more localized treatment outcomes achieved in a shorter period of time, Jakyakgamcho decoction was reprocessed into a form of pharmacopuncture. An analysis of Jakyakgamcho decoction pharmacopuncture showed that there was a significant loss of paeoniflorin(Jakyak's index component). This study was designed to investigate ways to minimize this loss. Methods : After making changes to the processing methods of Jakyakgamcho decoction pharmacopuncture, we measured the quantity of paeoniflorin using high performance liquid chromatography(HPLC) for a before-and-after analysis Results : Paeoniflorin loss was observed 15 minutes after sterilization with $Na_2HPO_4$ at $121^{\circ}C$ Conclusions : It was found that paeoniflorin loss did not occur when pH was not controlled for during processing.

  • This expressway passing the address region that is sightseeing of our country must consider in what do a convenience sincerity chase and a cultural side view. A region with development possibility and a spinoff about a cultural element must hold consideration at the same time to a sightseeing resort. This route that passed Gang-Reung, Yang-Yang, Sok-cho was connecting an obstetrics acid, and accessibility along investigation was a hard place. In this region, a classic house is tying scattered, and JeonSaCheong inviting an ancestral mortuary tablet is appearing. The private house was divided during a classic house by using typical Gangwon to the room where a floor was introduced by house with several wings Korean floor heater center form. A characteristic form a characteristic change was appearing on each rooms and structure, a plane according to the times, and to execute extension with a lease in a direction too was able to be seen, and Confucianism a little culture very remained in construction, and a memorial service space, a closet were able to be seen. Also, this local high house had a lot of regions composed of a relative and was with doing in the village that did to these house several houses.

  • In recent years, there is increasing demand of esthetic design and complex function in aerospace, automobile and die/mold industry, which brings into limelight high-precision, high-efficient machining of sculptured surface. This paper deals with the establishment of the optimal tool path on free form surface in high speed ball end milling. Ball end milling is widely used for free form surface die and mold. In this machining, the cutting direction was changed with tool path. The cutting characteristics, such as cutting force and surface form are varied according to the variation of cutting directions. In this paper, the optimal tool path with down cutting in free form surface cutting is suggested.
