A survey was conducted to 252 owners of restaurants and taverns who, during the period of from Jan, 1 1998 to Sept.15 1998, were ordered by the authorities concerned to suspend their businesses due to the violations of relevant laws an regulations. Out of 252 questioned 195(77.4%) were those who completed the required orientation course for owners of the above businesses. It is found that the rate of completion of the course are higher among those who had been running the business for a longer period of time, and alwo among those who had bigger facilities. Asked how they found the current laws and regulations relevant to their businesses, 68.7% of the surveyed replied that the existing laws and regulations should be abided by while 26.6% wanted flexible application of the laws and regulations. Those who demanded complete revision of the laws and regulations were only 4.8% of the questioned. Restaurant owners marked the high rate of 71.3% in the support of the existing laws and regulations, while tavern owners' supporting figure was around 60%. Analyzing the owners of restaurants and taverns who were ordered to suspend their businesses due to their violations of the relevant laws and regulations, it was found that female owners, owners with higher ages, less educated owners and owners of taverns were more likely to violate regulations than the others. And the older establishments, the smaller in size of establishment, and establishments with lesser number of employees were also found to be more likely to make violations. The reasons for the suspension of businesses were as follows in its order of percentage; violation of business hours(37.7%), selling of alcohol to minors(13.9%), abnormal business activities(12.7%), indecent entertainment(10.3%), employment of under-aged waitresses(8.3%). Public prosecutor's office, police, municipal office and district office of a city are empowered to enforce the relevant laws and regulations on restaurants and taverns and to suspend businesses, 43.3% of all the suspension of businesses were made by district offices and 42.5% of them by police, 48.8% of the respondents showed their preference for district office to other law enforcing agencies. Next came municipal office with 29.4% followed by public prosecutor's office(25.0%) and police(21.8%). 77.0% of the questioned answered that they would rather have paid fine than having been suspended of businesses. And most of the owner of the suspended businesses replied that the duration of suspension of businesses must be shortened. Most of the owners of restaurants and taverns who had experienced suspension of businesses(94.0%) replied that they would close their businesses for good if their businesses were suspended again. Asked to make any proposal or suggestion, 67.1% of the surveyed wanted that when any violation were found by the law-enforcing agencies the owners of the businesses were given a chance to correct it before being booked for violation.

골밀도가 높고 두꺼운 피질골에 마이크로임플란트를 self-drilling 방식으로 식립하는 경우 과도한 수준의 골부하(bone loading)가 발생할 위험이 있으며 이는 인접골의 정상적인 골개형(bone remodeling)에 장애를 초래할 수 있다. 이에, 본 연구에서는 유한요소해석으로 두께 1.0 mm의 피질골에 Absoanchor SH1312-7 마이크로임플란트((주)덴토스, 대구, 대한민국)가 self-drilling 방식으로 식립되는 과정(10회전, 식립깊이 5 mm)을 모사(simulation)하였으며 식립 단계별로 피질골에 발생되는 스트레인을 조사하였다. 식립중 마이크로임플란트 첨부의 절삭연(cutting flute)에 의한 골삭제로 생기는 나사길(threaded groove)의 치수를 얻기 위하여 가토 경골에 마이크로임플란트를 식립/제거한 후 Micro CT (Explore Locus RS, GE Healthcare, Ontario, Canada)를 이용하여 기하형상을 측정하였으며 이를 치밀골의 유한요소모델에 반영하였다. 해석결과, 치밀골에 발생되는 스트레인은 임플란트 식립깊이에 따라 증가하였고, 초기단계에서 나사산에 인접한 골에 국한되던 과부하 부위(스트레인이 4,000μ-strain을 상회하는 영역)가 식립깊이 증가에 따라 인접골 전체, 즉 나사산 인접부는 물론 골(valley) 부위에 접하는 모든 영역으로 확장되었다. 본 연구를 통해, self-drilling 방식으로 마이크로임플란트를 식립할 때 치밀골에 발생하는 스트레인 크기는 생리적인 골개형을 저해할 수 있는 수준임을 확인할 수 있었다. Objective: The aim of this study was to evaluate the strain induced in the cortical bone surrounding an orthodontic microimplant during insertion in a self-drilling manner. Methods: A 3D finite element method was used to simulate the insertion of a microimplant (AbsoAnchor SH1312-7, Dentos Co., Daegu, Korea) into 1 mm thick cortical bone. The shape and dimension of thread groove in the center of the cortical bone produced by the cutting flute at the apical of the microimplant was obtained from animal test using rabbit tibias. A total of 3,600 analysis steps was used to calculate the 10 turns and 5 mm advancement of the microimplant. A series of remesh in the cortical bone was allowed to accommodate the change in the geometry accompanied by the implant insertion. Results: Bone strains of well higher than 4,000 microstrain, the reported upper limit for normal bone remodeling, were observed in the peri-implant bone along the whole length of the microimplant. Level of strains in the vicinity of either the screw tip or the valley part were similar. Conclusions: Bone strains from a microimplant insertion in a self-drilling manner might have a negative impact on the physiological remodeling of cortical bone.

This study is conducted to examine the heat/moisture transport properties and wearing performance of high-tech fabrics for comfortable sportswear which have several factors such as fiber type, fiber content, yarn number, yarn density, weaves and areal weight by means of KES--F system measuring device with 15 kinds of fabrics in which the therproperties included the basic mechanical properties. And also the moisture transport properties were measured by standard test method. Finally, we have obtained useful specification for fabrication the quickly wick perspiration/drying high-tech fabrics for comfortable sportswear. (1) The specially-engineered polyester fibers used in woven fabrics (brushed fabric and normal fabrics) transport perspiration away from body to the surface of the garment, where it can evaporate quickly. At the same time, fabric dries quickly. Fabric can be machine-washed and retain its shape for long time. (2) Develfabric (#PK-3) is a new type of specialty knitted fabric. It has a double-layer construction consisting of a dry layer and a moisture absorbing layer, and offers perspiration absorption and transpiration properties that are ideal for sports activities in which the wearer perspires heavily. During and after exercise, perspiration is quickly wicked to the outside, leaving the skin always feeling dry and comfortable.
