This paper deals with the vibration and noise characteristics of three different kinds of pipe structures (PVC pipe, cast-iron pipe and newly developed pp pipe). In order to measure the structure born noise, an impact force generated by dropping a small ball was applied to three different kinds of pipes. It was confirmed that the structure born noise could be reduced by employing a high damping material. Also, transmission loss of a pipe was investigated for various frequency ranges by using a speaker as a sound source.

The development of internet environment in the society caused the travel industry to proceed into the internet business competitively. However, a little research has been conducted on the netizens' behavior in the internet travel businesses. This study attempted to address the behavioral aspects related to the internet use for salaried men visiting internet travel agencies(ITA). Research findings are as follows: 1)Netizens seemed not to invest much time in searching travel-related sites. Major purposes of their visiting ITA were acquiring travel information, hotel/condominium reservation, package product reservation, etc. 2) They thought the provision of travel information, protection of private information, and internet connecting speed important in purchasing travel product through internet. 3) They revealed high intention to visit ITA, but low to purchase goods. However, netizens who had experience of purchasing goods show higher intention to visit or purchase than those who did not visit ITA even one time.

Rheumatoid arthritis is a common articular disorder with a characteristic radiographic picture. A symmetric polyarticular disease of the synovial joints of the appendicular skeleton is apparent, with prominent abnormalities of the proximal interphalangeal and metacarpophalangeal articulations of the hand, the wrist, the metatarsophalangel joints of the foot, the posterior and plantar aspects of the calcaneus. the knee, the elbow, the glenohumeral and acromioclavicular joints, the ankle and the hip; these abnormalities are commonly combined with changes in the cervical spine. This distribution of synovial joint involvement is sufficiently common to allow accurate diagnosis, especially when the involvement is characterized by fusiform soft tissue swelling, periarticular osteoporosis, marginal and central osseous erosions and cyst, and diffuse loss of interosseous space. Occasionally a rheumatoid arthritis patient will have a coexistent articular disorder and in these cases, careful analysis of the radiographic changes usually provides some clue indicating the presence of a second disease.

임장빈,이진우,차경석 대한치과교정학회 1996 대한치과교정학회지 Vol.26 No.5
본 연구는 현재 브라켓의 개발 양상이 tip, torque 등이 브라켓 내에 내재되어 있는 straight wire appliance의 도입으로, 브라켓의 디자인은 더욱 세밀하고, 복잡해져 점차 고가화 되어 재사용의 요구가 증가하는 점에 맞추어 계획되었다. 본 연구의 목적으로는 재생과정의 목표에 부합하는 브라켓 접착면의 재처리 방법을 찾는 것이다. 실험 방법은 금속 브라켓, 도재 브라켓 각 5개씩 5군으로 나누어 브라켓 기저부에 재처리과정을 시행한 후, 이를 치아에 접착하고 만능 시험기(universal testing machine)을 사용하여 치아에서 브라켓이 탈락하는 시점의 최대 전단접착강도를 채득하였으며, 그 후 치아의 법랑질 표면을 입체 현미경으로 관찰하여 파절면의 접착제 잔류지수를 구하였다. 또한 입체 현미경 (stereoscopic microscope)과 주사전자현미경 (SEM) 화상으로 재처리된 브라켓의 접착면을 관찰하였다. 이와 같은 실험으로 다음과 같은 결론을 얻었다. 1. 금속 브라켓에서 접착 강도가 가장 높은 재처리 방법은 sandblasting을 8초간 시행한 군이었으며, 이는 제조회사에서 제작된 원래 상태인 대조군의 접착강도보다도 오히려 높았다. 2. 세라믹 브라켓에서 접착 강도가 높은 재처리 방법은 8초간 sandblasting한 군이었으나, 대조군의 접착강도 보다는 낮았다. 3. Sandblasting 시간을 4초에서 8초로 증가시킨 경우 금속 브라켓의 접착강도는 급격히 증가하는데 비해 도재 브라켓의 접착강도는 별 차이가 없었다. 그 이유는 도재 브라켓의 경우 브라켓 접착부의 표면적 증가에도 불구하고, 금속 브라켓과는 달리 브라켓 자체의 물성 차이로 인해 도재 브라켓에서의 접착력을 좌우하는 거대 기계적 결합부위의 파손이 일어나 접착력의 약화를 가져왔기 때문이다. The purpose of this study is to find the optimal reconditioning method for a debonded bracket base. In this study, metal brackets and ceramic brackets are used. There are devided into five groups by reconditioning methods (A : control(new bracket). B : heat treated, C : grinded with green stone, D : sandblasting for four seconds, E : sandblasting for eight seconds). Each reconditioned brackets were bonded and shear bond strength was measured by universal testing machine. After debonding, enamel surfaces were examined under stereoscopic microscope to determine the adhesive remnant index. The Microstructure of reconditioned bracket were examined by SEM (JSM 5200, Japan) and stereoscopic microscope (SZ-ST, Japan). 1. In metal bracket groups, sandblasting for eight seconds revealed the greatest shear bonding strength and its strength was above that of control group. 2. In ceramic bracket groups, sandblasting for eight seconds revealed the greatest shear bonding strength but its strength was below that of control group. 3. As sandblasting time was increased, shear bonding strength of metal bracket was increased very much, but in ceramic brackets, shear bonding strength exhibited limited increase. This difference was caused by macro-mechanical retentive areas of ceramic brackets were broken for their brittle characteristics of material.
