The purpose of this study was to investigate the antique chair style in Korean market. The examined objects were 235 chairs in selected 30 antique shops dealing with curios in Seoul from July 16 to August 23 in 2002. The results of this study was as follows Antique chairs in Korean market are revival style and eclectic style. The revival style are copied or transformed period style antique chairs. The eclectic style are chairs newly designed by mixing of 2 or 3 different types period style antique-chairs. Rococo-revival style were the most prevalent following Renaissance style chairs in the market. In case of chair back and legs the Classic revival style are made by copying and transforming the Klismos, Hepplewhite, Sheraton, which is a neo-classic style. The Gothic revival style are copied or transformed finial, foil, crocket and tracery which is the Gothic architectural decoration. In Renaissance revival style. Elizabeth, slat, caned, padded, yorkshire, bobbin turned, William & Mary are copied and transformed for the chair back. In Rococo-revival style, LouisXV, Queen Anne, Chippendale of Rococo-style- chair back and cabriole legs are copied or transformed. In the eclectic style, Classic style chair back with Renaissance-style legs or Rococo style chair back with Renaissance style legs are combined as a periodical eclectic style. In this manner now style of chair back and the periodical style of legs were used together as a new eclectic style chair.

Objective : This study was designed to assess the protective effects of Chengwhabosimtang on the animal model of depression, chronic mild stress(CMS). Method : Male Sprague-Dawley rats Were used for this experiment. The subjects Were divided into 3 groups (1. CMS-drug: Chengwhabosimtang administered during CMS treatment, 2. CMS-vehicle: water administered, 3. normal ). After 4 weeks of CMS treatment they were executed Forced swimming test(FST) and Elevated plus maze. Tyrosine hydroxylase(TH) in ventral tegmental area(VTA) and c-Fos in paraventricular nucleus(PVN) were measured. Result : 1. In FST, CMS-drug group showed significantly decreased immobility behavior. 2. CMS-drug group showed no significantly lower TH level in VTA than CMS-vehicle group. 3. CMS-drug group showed significantly less c-Fos expressed cell bodies in PVN than CMS-vehicle group. 4. In Elevated plus maze, CMS-drug group showed no significantly anxiety. Conclusion : These results suggest that Chengwhabosimtang may have protective antidepressant effects in CMS model rats. And these effects could be explained by the elevated stress-copying behaviors which are related with PVN of hypothalamus and dopaminergic neurons in VTA.

Plasma arc cutting is a fusion cutting process in which a gas-constricted arc is employed to produce a high-temperature, high-velocity plasma jet on the workpiece. This process provides some advantages such as increased cutting velocity, excellent working accuracy and the ability to cut special materials (widely used stainless steels and Al-alloys, for example), when compared with iconventional oxyfuel gas cutting. From the view point of price and reliability of the power source, plasma arc cutting has also some distinct advantages over laser beam cutting. High-speed machines with NC or CNC systems are needed for the plasma arc or laser beam cutting process, while for oxyfuel gas cutting, low-speed machines with copying templates or optical-shape tracking sensors can be applied. The low price and high flexibility of the microprocessor arc contributing more and more the application of CNC system in the plasma arc cutting process, as in other manufacturing fields. From these points of view, a microprocessor-based plasma arc cutting system was developed by using a reference-pulse system, and its performance was tested. The interpolating routines were programmed in the assembly language for saving the memory volume and improving the compouting speed, which has an intimate relationship with the available cutting velocity.

Purpose: This study investigated the relationships of handwriting legibility and perceptual-motor skills, and handwriting speed and perceptual-motor skills. And identified the predictors that most affect the handwriting of preschool children. Methods: Twenty-three typically developing preschool aged children (mean age: 68.61 months, SD=2.04) were selected through the Korean-Denver Developmental Screening Test-2(K-DDST-2). The children were tested with regard to handwriting legibility, visual perception, visual-motor integration and fine-motor coordination. Results: First, a significant relationship was not found among handwriting legibility, visual perception, visual-motor integration and fine-motor coordination. Second, a significant relationship was found among handwriting speed, visual perception and fine-motor coordination. Third, stepwise multiple regression analyses showed that general visual perception were significant predictors for handwriting speed. Conclusion: Occupational therapists should evaluate children's visual perception levels utilizing a standardized test, and focus on general visual perception in order to improve handwriting skill(speed). Also, occupational therapists are expected to play an important role in the management and treatment of children's handwriting skills.

본 고에서 우리나라의 클러스터들이 세계에서 경쟁력 있는 혁신클러스터로 자리매김 할 수 있는 잠재경로와 클러스터의 형성을 촉진할 수 있는 정책개입의 방향에 대하여 탐색하고자 한다. 세계적인 클러스터가 되기 위해서는 클러스터의 구성원들이 끊임없이 변하는 자본주의 경제의 전환력에 대하여 집단적으로 대응하는 것이 필요하고 그 과정에서 각기 독특한 경쟁력이 창출된다는 것이 이 논문의 핵심적 주장이다. 우리나라는 급속한 경제성장 과정에서 다양한 자산들을 축적하였고 이런 자산들은 우리나라에서 세계적인 선도 클러스터를 창출하는 데 효과적으로 활용될 수 있다. 이 과정은 실리콘밸리와 같은 유일한 모델을 베끼는 것이 아니라 한국의 지역적 조건에 맞는 독자적인 모델을 창출하는 것이다. 이를 위해서 우리나라 혁신클러스터의 재창조 과정이 요구된다.

This research was designed to study the different kinds of ancient patterns applied to the Korean traditional suit and the symbolism associated with these patterns being used the prevalent Han-bok collections in markets. The shapes and changes in the use of the patterns can be summarized as follows. The published collections in the last 5 years were specifically concentrated between 1996 and 1997, proving that the development in Han-bok designs was most active during that time. But the trend decreased due to the effects of a depressed domestic economy. The plant pattern was the most utilized pattern for practical purposes. It looks beautiful and it is also easily manufactured with open space. Symmetrical and linear arrangements make customers feel stable at sight and these patterns tend to attract public gaze resulting in increased sales. There is a problem whether to continue using the existing patterns of the Han-bok without any correction or whether to copy the pattern of the kimono or the western suit. Copying other patterns definitely hurts the elegance of the Han-bok. It is time for us to not only keep our own traditions but also to study and develop new patterns that are distinct from the Chinese and Japanese patterns. The following are suggested as the basic materials.

The wooden pagoda was first appeared in about late 4th century in Korea. And between the late 6th century and the eary 7th centry, the multistoried wooden pagoda was replaced with the stone pagodas, in order to improve their stability and durability. In Three-kingdom and Unificated-Silla period, there are two types of stone stupas in Korea. The one is Paekche(百濟)style, and the other is Silla(新羅) style stone pagoda. These two styles are basically different in each part like podium, roof stone, body stone, structure and the others. Two types of stupas are distributed in two regions which devided into the East(Silla territory) and West(Paekche territory) in the Korean peninsular. The origin of the Korean stone pagoda can be traced to the Paekche dynasty and Silla dynasty. The former were the result of the careful study of their skillful wooden pagodas, where the latter were actualy originated from copying their sundried brick pagodas with stone. Two important pagodas of the primitive stage are the stone pagoda of Miruksa(彌勒寺) temple in Iksan and Bunhwangsa(芬皇寺) temple in Kyungju. These two pagodas are compared with each other in the style of their construction. Silla style have sharp straight lines and short distance between roof stone and eaves. They give us strong as well as intelletural feeling. Howerever, Paekche style has curved lines and dull angles of cutting area of stone, they give us soft feeling.

For the reuse of the existing 3D block model of a ship, we analyze the hull modeling process using AVEVA Marine which is a representative CAD (Computer-Aided Design) system for the shipbuilding. In the AVEVA Marine environment where the design engineer makes 3D model on the 2D view that is so-called 2.5D, it cannot be possible to copy to reuse the block model just simply copying the 3D feature model itself like in the general mechanical CAD system or Smart Marine 3D which are on the basis of the 3D model representation. In this paper, we analyze the scheme file where the 3D model is defined in AVEVA Marine so that we develop the program for the block copy and the translation using this scheme file. It is significant that this program can be immediately available as a real-world application on the AVEVA Marine environment.
