This study defined the way to distribute power of forward channel and suggested a new model for prediction power in order to minimize the deterioration of call quality and performance in the CDMA mobile communication system of narrow band using 1.2288MHz of narrow band. Each change in Ec/Io was measured for the factors affecting wireless environment(e.g. the changes in power of overhead channel, the changes in a number of call channel, and the increase in interference from the additional facilities of adjacent base station or other systems) to know the influence on the wireless environment of forward link. The new way for power distribution to a base station in operation and its validity was checked by comparing before and after test.

To activate traditional markets under deterioration, Korean government have carried out the environmental renewal policy of the traditional market including the induction of arcades. The purpose of this study was to provide the basic information on the design standard of arcade in the traditional markets by 1) analyzing the present condition and the environmental renewal policy of traditional market and grasping the tendency of renewal policy, 2) classifying the street markets into 5 types and finding the street market type that often applied the arcade and 3) selecting two traditional markets that had arcades and investigating the actual condition by the questionnaire to merchants. As a result of the study, the arcades will be introduced for improving the environment of 11 traditional markets that have the streets(width 6m·12m) and many 2-story buildings. And the merchants thought fire safety problem and thermal environment to be important.

To study the caries patterns in primary dentition, 719 preschool children, 4-6 years old, were examined for their caries activity(salivary reductase activity)and caries experience of individual teeth. Teeth froups were made by cluster analysis using dft of individual teeth as criteria. The six major teeth groups in the order of dft index from high to low were (1) lower primary molars, (2) upper primary molars, (3) upper central incisor, (4) upper lateral incisor, (5) canines, and (6) lower incisors. There were significant differences in dft index between teeth groups except upper lateral incisor and canines. Upper and lower primary molars showed the highest correlation in dft index, and the next couples were upper central incisors and upper lateral incisous, upper lateral incisor upper lateral incisor and canines, upper central incisor and canines, upper lateral incisor and upper primary molars, and canines and upper primary molars in descending order. Upper first primary molar showed the greatest differences in dft index between caries activity levels.

치료시기에 따른 상악골 전방견인효과 : 사춘기전과 사춘기의 비교 A comparison of prepubertal and pubertal patients

상악골 전방견인 장치를 이용한 골격성 Ⅲ급 부정교합 환자의 악정형적 치료에서 치료시기는 치료효과에 지대한 영향을 미칠 수 있으며 이상적인 치료시기는 연구자에 따라 다소의 차이는 있으나 다른 형태의 부정교합보다는 다소 이른 사춘기 이전의 어린 나이라는 것이 선학들의 공통된 의견이었다. 하지만 통계적 자료들을 바탕으로 한 최근의 논문들은 과거 선학들의 의견을 뒷받침 해주는 논문과 그렇지 않은 논문들로 나뉘고 있어 이상적 치료시기에 대한 정립된 의견이 없는 실정이다. 이에 본 연구에서는 119명의 환자들의 수완부골 방사선 사진을 평가하여 골성숙도에 따라 사춘기전군과 사춘기군으로 분류하고 치료전후 측모두부방사선 사진을 분석하여 상악골 전방견인에 대한 치료효과를 비교하였다. 평균 치료기간은 사춘기전군은 6.5개월, 사춘기군은 6.1개월이었으며 치료전후의 측모두부방사선 사진을 분석한 결과 다음과 같은 결론을 얻었다. 1. 상악골의 전방이동양은 사춘기전군과 사춘기군간에 차이에 없었다. 2. 상악골의 하방이동양은 사춘기전군과 사춘기군간에 차이가 없었다. 3. 하악골의 하방이동양과 후하방회전양은 사춘기전군과 사춘기군간에 차이가 없었다. 4. 치성이동양은 사춘기전군과 사춘기군간에 차이가 없었다. 이상의 결과로 사춘기전 뿐 아니라 사춘기에서도 상악골 전방견인에 의해 상악골 성장촉진과 함께 성공적인 악정형 치료가 가능함을 알 수 있었다. Treatment timing is a very important factor to consider in treating skeletal Class Ⅲ patients by means of maxillary protraction. According to the literature maxillary protraction should be carried out at an early age before puberty. However, no scientific data were presented to support this statement and recent studies supported by statistical data showed disagreement concerning the optimum treatment time of maxillary protraction. Therefore, there is no agreement about the optimum treatment time of maxillary protraction. In this study hand-wrist X-rays were taken from 119 patients and subjects were grouped into prepubertal and pubertal group according to their skeletal maturity . Preagreement and posttreatmrnt lateral cephalometric X-rays were taken and treatment effects were compared. The average treatment time was 6.5 months for the prepubertal group and 6.1 months for the pubertal group. The obtained results were as follows : 1. The amount of maxillary forward movement was the same for prepubertal and pubertal group. 2. The amount of maxillary downward movement was the same for prepubertal and pubertal group. 3. The amount of mandibular downward and backward rotational movement was the same for prepubertal and pubertal group. 4. Dental effects were the same for prepubertal and pubertal group.

The movement which is trying to evaluate the view as the economic value is happening as well in korea now and these movements are being reflected as it is in social phenomenon than academic world. In Seoul, the ownership of an apartment unit with views of rivers, mountains and something like that are more expensive than the others by US$ 50,000 to US$200,000. And Also many legal disputes take place because of the new buildings blocking the views of the others. Therefore, we develope the method that can objectively evaluate the views in each apartment unit. The studies are being started to solve the points at issues on the evaluation of view by fitting into those tendency and trend lately but clear standard has not been thesis yet. One of problems is to define where the view space and the view point are in the apartment unit. Therefore this study is aiming the purpose of providing the view space and the viewpoint, one of quantitative standards to evaluate the view in the apartment unit. To present the methodology to establish the datum point of view, 1) precedent studies were scrutinized, 2) questionnaire to residents was conducted, 3) the indoor standard space was defined and 4) the visual characteristics in the room were analyzed.

Modern complex city has a meaning as a place of interaction between human behaviors and physical environments consisting of buildings, street furnitures, streets and so on. Street, one of physical environments, plays a important role in determining the image of city as a symbolism of civic culture and a functionalism in itself. Especially building, a component of streetscape, has directly expressed the symbolism and functionalism that street has, and therefore the architecture in streetscape can be defined a behavior that visually organize its components into expressing the symbolism and functionalism of street. But those of street as a aesthetic value is not properly reflected to building design because of preference policy of the Korean Government for development. As a result of that, streetscape has been gray and complicate rather than beautiful and consistent. Facade design of building as a major component of streetscape is very important for the image of the street but the intentional intervention of that in building design is not easy without building owner's positive comprehension and active participation in that most of buildings is private property for self-interest. This study aims to come up with evaluation model that can quantitatively interpret the influence of facade designs and colors of existing buildings on the selected street with understanding characteristics of it, and illustrate the model through the experimental questionnaires.

The purpose of this study was to analyze the smoke eliminating performance of an arcade-type conventional market. In this study, the effect of the openings for the ventilation about the smoke eliminating performance was analyzed. For the fire simulation, the air flow caused by high-buoyance effect should be considered. CFD(Computational Fluid Dynamics) method and compressible k-ε model was used in this study. The indoor temperature and the smoke concentration could be lowered by the openings of the arcade.
