This study is for the investigation of form using the aluminum-compound metal frame(Aluminum frame reinforced panel : AFR panel) which is improved in the capacity in the wall-concrete structure in steal of using the existing form which has problems such as, excessive exposure of cement, the loss of labor when it is constructed or disjointed, and it's economical efficiency compared with that of EURO Form. AFR panel passes the KS F 8006 test, and as a result of field test, it's displacement is satisfied with Specification. And using AFR panel is more economical than that of EURO Form because saving labor cost which plays a major part in cost saving in formwork is more effective in retrenching total cost than increment of material cost.

The purpose of this study is to present the form of Korean policeman's headgear which is endowed with traditional Korean characters and a creative property that has distinctive from other headgears. The investigation was carried out through the researh of policeman's headgears in foreign countries such as United Kingdom France Belgium Italy germany and Japan. The dom-estic investigation was carried out through the Focused Group Interview and analysis on the domestic policeman's service and headgear. Lastly the research into the characteristic of Korean traditional headgear's from was carried out. Consequently two types of policeman's head-gear hat and cap were newly developed and the system of practical use was suggested. The results of this study were as follows: 1. Through the use of traditional and formal elements of Korean ancient headgears korean policeman's headgears were improved in distinc-tion and dignity. 2. Through the use of unisexual form police-man's headgears were improved in uniformity. 3. Through the use of transformal accessories policeman's headgear were improved in simplified system. 4. Through the use of newly formed and lighten weighted materials policeman's head-gears were improved in functionability.

The Contour Crafting(CC) process, which has been developed at the University of Southern California, aims at automated construction of whole houses as well as sub-components. For this purpose, new trowel mechanism is basically needed in order to fabricate the true 3D shape. This paper presents our concepts and initial investigation of 3D free form fabrication using the pivoting side trowel. Specifically, the status of research and development of the processand experiments with ceramics materials, and its potential application areas are detailed.

This study deals with apartments, the representative form of residence in Korea, and analyzes the residential plane of 30-pyong apartments that are constructed by the 5 construction companies within in the past three years. It is discovered that these apartments show a certain form and that developing the frame work of interior elements according to the characteristics of family types of 30-pyong apartment residents and the process for such a frame work are needed. Therefore, by analyzing the differences of residential forms according to resident types, this investigation tries to approach the design centering around users. To summarize the steps and contents of this study, first, it draws the understanding and the study field of common residential space, second, it shows the characteristics of family types within residential space, third, it analyzes and verifies the differences of characteristics according to family types within the representative size and form of plane. This investigation is aimed to provide the reasons for developing different planes according to family types despite they may be of the same size, to show the frame of the study method for developing the plane design and the interior element design for users and to suggest the way of designing residence in a conditional approach applying the conditions of users within common residential space.

The recent completions of free-form spatial structures provide us a very attractive form. To realize such an extraordinary shape, it is absolutely necessary that the connector systems have to be investigated the characteristics of the systems and analyzed with a practicable method. In this context, this research consists of not only literature research but also numerical analysis with selected connector systems, which was adopted in real free-form spatial structures. For numerical analysis, especially, finite element analysis (FEA) is performed with a various test parameter using a commercial program ANSYS. Consequently, the general characteristics of node connectors the moment-rotation-curves are presented by considering a large deformation effect as well as a multi-linear material properties.

최근 각종사건 수사에 디지털 증거의 효용성이 증대되고 있다. 디지털 저장매체가 실생활에 폭넓게 사용됨에 따라 유죄입증이 가능한 결정적 증거가 디지털 형태로 남겨져 있는 경우가 빈번하게 발생하고 있기 때문이다. 현재 세계 각국의 수사기관들은 디지털 증거의 효용성을 극대화하기 위한 노력에 많은 관심을 기울이고 있다. 우리나라에서는 디지털 증거의 신뢰성 보증 모델 등에 관한 연구가 컴퓨터 공학, 형사법학 분야 등을 중심으로 꾸준하게 진행되어 왔다. 그러나 수사기관의 수사기법이 신종 범죄를 쫓아가는 상황에서 수사기관의 입법상, 기법상 공백은 발생할 수 밖에 없는 한계를 겪을 수 밖에 없다. 우리나라는 현재 디지털 증거에 관한 명확한 법규가 마련되어 있지 않고 전문 수사 인력이 부족한 실정으로 디지털 수사의 입법적 흠결 보완과 수사기관의 조직개편 등이 요구되고 있다. 본문에서는 날로 전문화되고 다양화되는 각종 사이버 범죄의 효율적 대응을 위한 핵심적 단서인 디지털 증거를 효율적으로 수사하기 위한 방안에 대해 논의하였다.

Data obtained from X-ray diffractometry, thermal analysis, IR spectroscopy and microscopic observation were used for the identification and characterization of four crystalline modifications of piroxicam. form a was crystallized from sodium hydroxide-hydrochloric acid and from c was obtained by crystallization from toluene. Form b and d was crystallized from methanol under the different temperature conditions. Relative rates of dissolution and solubility of four crystal forms of piroxicam in distilled water were measured.

An investigation into asymmetric vibrations of a clamped circular plate under a hannonic excitation is made. We examine a primary resonance, in which the frequency of excitation is near the natural frequency of an asymmetric mode of the plate. We found not only a response having the form of standing wave but also one having the form of traveling wave, which was not observed by Sridhar, Mook and Nayfeh(1978; Journal of Sound and Vibration 59(2), pp. 159-170).

Five polymorphic modifications of Cephradin were prepared by recrystallization from organic solvents. The isolated crystal forms were characterized by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and X-ray crystallography powder diffractometry. Modificaition 1 was the most stable form and decomposed at $201.3^{\circ}C$. Modification 3 and 4 were metastable. The dissolution of modification 3 and 4 was faster than that of marketed form.
