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.

One of the screening tests used for identifying the high risk group of adolescent drug users is High Risk Group of Adolescent Drug Users Screening Test (HIRIGADUST) developed by Kyung-Bin Kim (1977) that consist of six subscales and 70 items. The Purpose of this study was to examine the reliability and construct validity of HIRIGADUST. HIRIGADUST was administered to 370 third grade middle school students. In the reliability test, the Cronbach’s α coefficients were 0.70-0.89 in five subscales, but the Cronbach’s α coefficient was 0.53 in ‘Personal experience and general environment’ subscale. The resulting of testing the construct validity of five subscales of HIRIGADUST by factor analysis provided evidence for the validity of the each subscales. We used T score 65 as a cut-off point. The cutting scores were 12 for ‘Peer relationships and school performance’ subscale, 14 for ‘Personality and value system’ subscale, 14 for ‘Psychological problems and health concerns’ subscale, 8 for ‘Family history and characteristics of parents’ subscale, and 14 for ‘Conserns about parents’ drinking subscale.

A culture statistical database system is a database system that can model, store and manipulate culture data in a manner well suited to the needs of users who want to perform statistical analyses on the culture data. Culture statistical databases have some special characteristics and requirements that are not supported by existing commercial database management systems. From the end user's perspective, whether the statistical calculations are being performed in the database or in a statistical package can be quite transparent, especially from a functionality viewpoint. However, once the datasets to be analyzed grow beyond a certain size, the statistical package approach becomes infeasible, either due to its inability to handle large volumes of data, or the unacceptable computation times which make interactive analysis impossible. In addition, an increasing number of applications today want the ability to perform interactive and on-line analysis of this data in real time, such as "what-if" analysis in forecasting. The emergence of multiple gigabyte corporate data warehouses, with on-line analytical processing and data mining type of analyses on them, is a good example of this trend. Hence, there is an increasing need for supporting culture statistical functions directly inside the database system. In this article we provide a general overview of culture statistical database design, with specific focus on the various technical issues and proposed approaches. By its very nature, the treatment here is brief, and many details have been omitted.

임순빈,최경규,박상진 大韓齒科保存學會 2005 Restorative Dentistry & Endodontics Vol.30 No.3

Mechanical removals in decayed teeth have been performed using drill and sharp hand instruments. These methods have some disadvantages such as pain, local anesthesia and overextended cavities Therefore chemo-mechanical excavation of dentin carious lesions has been introduced. The purpose of this study was to evaluate the efficacy of traditional mechanical methods using burs and chemo-mechanical methods (Carisolv) of caries dentin. Mechanical caries removal was carried with low speed round bur Chemo-mechanical caries excavation was performed with Carisolv (Medi-team), using the Carisolv hand instruments. The mean time to remove caries with two different methods was evaluated and the data analyzed with SPSS software (ver 11.5) by t-test (p < 0.05). For histomorphometry of caries removal were also carried with mechanical or chemo-mechanical (Carisolv) methods from 20 extracted caries permanent molars. Complete caries removal was verified with a #23 sharp explorers, Caries Detector (Kuraray Co. Japan), and standard apical radiography. 1. Chemo-mechanical method was taken more times than mechanical method (1.5 fold) (p < 0.05) 2. Excavation for caries took more time for molar lesion than premolar lesion, and the least time was taken to remove the caries in incisor lesion (p < 0.05). 3. There were no significant differences to remove the caries between the maxilla and mandible (p > 0.05). 4. The remaining carious dentin was detected after the ckemo-mechanical removal of the carious dentin, and no smear layer were seen after the mechanical and chemo-mechanical removal of the carious dentin. 본 연구는 우식의 기계적 제거와 기계화학적 제거의 효과를 비교, 평가하고자 하였으며, 기계적 제거방법은 저속의 round bur로, 기계 화학적 제거 방법은 Carisolv로 우식을 제거한 후, 잔존 우식을 확인하여 소요시간을 측정하였고, 또 실험실에서 발치한 우식 대구치 20개를 위 두 가지 방법으로 우식을 제거 후, Villanueva bone stain액으로 염색하고 표본을 제작 후 관찰하여 다음의 결론을 얻었다; 1.우식제거에 평균소요시간은 기계화학적 제거가 기계적인 제거보다 1.5배 더 길게 나타났다 (P < 0.05). 2, 우식제거에 평균소요시간은 소구치보다 대구치에서 더 길었고, 전치에서 가장 적은것으로 나타났다 (P < 0.05) 3. 상 · 하악에서는 차이가 없었다 (P > 0.05) 4. 기계화학적 방법으로 우식 상아질을 제거 시 잔존 우식 상아질이 관찰되었으며 두 방법 모두 우식 상아질을 제거한 표면에서는 도말층을 관찰할 수 없었다.

류마티스 관절염의 방사선학적 진단

주경빈 한양대학교 의과대학 1998 한양의대 학술지 Vol.18 No.1

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.
