In 1997, Yongsan-gu Office of Seoul held a design competition for 'Hyochang Park as a holy Grounds'. Although various shrines and monuments were located in it, Hyochang Park had lost its sense of pace as a 'holy grounds' mostly by its neighborhood-park-like atmosphere at its entrance area. Specific requirement for this competition was designing a 'symbolic object' to make this park more 'holy grounds' looking. However, it was very regretable that Yongsan-gu Office did emphasized on the 'object' rather than on the space or place in this design competition. Three points were emphasized in the winning scheme proposed by the author: where the object be located in the park, how the object be connected with the rest of the park, and how the object harmonized with some of traditional looking architectures and shrines. The purpose of this paper is to articulate the concept of the winning entry in detail and to describe how the concept actualized in reality.

We treated the persistent ruminative vomiting of a 13-year-old autistic boy by using a behavioral and psychopharmacological approach in a closed ward. Before the interventions, the patient had lost about 10kg of body weight due to very high-frequency ruminative vomiting. Together with psychopharmacological trials, the psychiatric treatment included a combination of a behavioral approach and food regulation that emphasized food restrictions, and we provided regular light meals. There was a considerable reduction of the ruminative vomiting and 2kg weight gain was achieved during the admission. These therapeutic gains were maintained at the 4-month follow-up assessment and the vomiting symptom reached a near-zero level and the weight loss were recovered by about 8kg. The issues related to the treatment approaches for ruminative vomiting with autism are discussed.

Iron loss is a possible source of performance deterioration, especially for a torque regulation, in field oriented induction machine. In this paper, study on the model of an induction machine with iron losses, a flux estimation strategy, the design of direct and indirect field oriented controller, a precise torque regulation scheme and the determination of a core lost resistance are discussed. Simulation and experimental results are also included and show the effectiveness of the proposed analysis and the proposed control strategy.

The disinfection effects of Trichloro isocyanuric acid (TICA) and Calcium hypochlorite (Cal-hypo) against E. coli' in aqueous suspension were compared at various concentrations of disinfectants as well as exposure times. When E, coil($^{\sim}10^7$ CFU/ml) were exposed by TICA and Cal-hypo (12 ppm each), 90% of the initial cells were reduced in 4 sec and 390 sec, respectively. Although Cal-hypo lost its disinfection capability in about 1 hr under the sun light, TICA maintained its effect up to 6 hrs. This comparative studies clearly demonstrate that TICA is more effective than Cal-hypo in terms of sterilizing E. coli as well as maintaining the disinfection effects.

An autonomous mobile vehicle for transport system must plan optimal path in work envimnrent without human supervision and obstacle collision. This is to reach a destination without getting lost. In this paper, a genetic algorithm for globaI and local path planning and collision avoidance is proposed. The genetic algorithm searches for a path in the entire and continuous free space and unifies global path planning and local path planning. The sinmulation shows the proposed method is an efficient and effective method when compared with the traditional collision avoidance algorithms.rithms.

This paper presents a new algorithm for surface segmentation and feature description. The algorithm extracts the signature of an edge image based on the signature technqique[12] in the first stage. If there exists a range in the angle axis where more than two signatures form a closed curve, we can conclude there is a surface inside the range. Using this feature of the signature, surfaces can be segmented. The surface features such as number of vertices, number of edges, and type of surfaces can also be extracted by finding the signatures of individual surfaces. This algorithm has distinguished advantages: it can easily recover the lost part occuring in the edge iage using the curve fitting method and it can extract surface features even when surfaces are rotated in 3-D space.

Lilium Miquelianum Makino is a species which originated in Korea. The Karyotype of the species was examined in materials collected at Mts. Kaya, Kasan, Chejung, and Kaji. The results are as follows: 1) The somatic chromosome number was found to be 2n=24. 2) The karyotype is described as: K=2Am＋2Bkm＋2Csst＋2Dsst＋2Ests＋2Fst＋2Gst＋2Hst＋2Ist＋2Jsst＋2Kst＋2Lst m: metacentric, sm: submetacentric st: subtelocentric, s: secondary constriction 3) A single subcentric supernumerary B-chromosome was found in some bulbs from Mt. Kasan. 4) The shape of the supernumerary B-chromosome was similar to that of the E chromosome which had separated at its secondary constriction and lost its lower chromosome fragment. 5) From three to eight nucleio of varying sizes were found in the telophase or interphase nucleus of root tip cells. The maximum number of eight nucleoli corresponds to the number of chromosomes that have a secondary constriction.

Towards the second half of 20th century the fashion market has become increasely fragmented reflecting the pluality of cultures. As a result style no longer had time to accrue individuality and so people lost interest. In the aftermath of this fashion has turned its atten-tion to its materials for inspiration and inno-vation. Taking their inspiration for new working designers have began to explore diverse materials and expressive techniques of tex-ture. Textural expression can change the im-age of a garment even on with the same structural design. This study is to present the crinkle express-ive technique of texture through the applied examples in contemporary fashion and related backgrounds. The result of this study testified the import-ance of texture as plastic element through various techniques of crinkle; 1) creasing technique is reminiscent of the delphos of Fortuny by modern materials 2) twisting tech-nique is that finished garment is twisted and crumpled by hand 3) shirnking technique is recreated method that is crushed and tied for granting the human touch to the material.

This study examines trends of children's play in Korea, and academic, pragmatic, and policy issues related to it. For the purpose, the researchers reviewed play theories, national and international views of play specialists, and research articles on children's play in selected academic journals published in Korea for the last 30 years. Although Korea has been active academically as well as politically in recognizing the importance of children's play, children's play in Korea seems to have lost its position, the true value of it being often distorted or unidentified. Many specialists worn that the deprivation of play opportunities increasing in modern societies will result in many serious problems. Play research therefore need to strengthen its power by being more accountable and broadening its foci toward solving such predictable problems.

The fracture of facial bone usually accompanies alveolar bone fracture and dislocation or fracture of teeth. Thus, aside from the reduction of fracture, the reconstruction of occlusion through the rehabilitation of lost teeth should be considered. The dislocation of tooth after trauma accompanying alveolar bone fracture needs bone grafting in case of implant treatment. Although autogenous bone graft shows good prognosis, it has the disadvantage of requiring a secondary surgery. This is a case of a mandibular condyle head fracture accompanied by alveolar bone fracture. The condylar head fragment removed during open reduction was grafted to the alveolar bone fracture site, thereby foregoing the need for secondary surgery.
