Background : The cun measurement System, an essential and convenient method in locating acupoints, has been widely used in the practice of acupuncture. However, traditional cun measurement has been criticized for its lack of reliability. Objectives : The purposes of this study are to determine if one cun measured by the directional methods have a consistency with that of proportional methods and to investigate which factors are related with these differences, especially in forearm. Methods : The distance between the elbow crease and the wrist crease of forearm was compared to a reference value of one cun obtained by the directional method. In this method, one cun is one third of the distance between index finger and Small finger of a subject, measured at proximal interphalangeal joint. In addition, to investigate the factors influencing the differences between these two methods, we measured the height and body weight and calculated body mass index (BMI). Finally we analyzed the factors correlated with these lengths by linear regression test. Results : The results showed that one cun obtained by the directional methods were significantly different from one cun by the proportional methods in forearm. It was demonstrated that the length acquired with the directional method was more correlated with body weight and body mass index, while the length obtained by the proportional method was more correlated with the height.

To investigate the histopathologic changes of the rabbit craniomandibular joint (CMJ), anterior disc displacement (ADD) was surgically induced. Of 15 rabbits, 9 were classified as experimental group, 3 as control of group, and 3 as sham-operation group, respectively The experimental group (9 rabbit) was subdivided into 6 weeks, 12 weeks, and 20 weeks group, respectively 3 rabbits. In experimental group, the disc was displaced anteriorly at the right side(operation side) and left CMJ was not operated(non-operation side). Both CMJs were harvested at 6, 12, and 20 weeks following surgery in experimental group. The CMJ was harvested at 6 weeks following surgery in sham-operation group. The specimens were examined under light microscope after hematoxylineosin and verhoeff staining. The obtained results were as follows: 1.In midsagittal view of control and sham-operation group, there were no degenerative and hyperplastic changes in the CMJ including articular disc, mandibular condyle, and temporal fossa. 2.Disc was shortened anterior-posteriorly and deformed of biconcave shape in all experimental group. In 20 week experimental group, intermediate zone of disc width was almost same as the width of posterior band of disc. 3.Soft tissue hyperplasia at the posterior attachment area of the disc and condylar hyperplasia were seen in the all experimental groups, but the degree of the hyperplasia was greater at 12, 20 weeks than at 6 weeks. 4.The number of elastic fiber in the disc proper was decreased and the direction and morphology was chanced in all experimental groups compared with those of control of groups. 5.Fatty degeneration was shown in non-operation side of 20 weeks experimental group. These results suggest that induced ADD in craniomandibular joint of rabbits could lead to a reparative and degenerative changes of the affected joint similar to those described for osteoarthrosis and osteoarthritis in human.

An agar degrading bacteria was isolated from the south ocean of Korea and was identified as Aeromonas sp. This strain produced the amount of agarase (1.4U/ml) with agar as a carbon source and casamino acid as a nitrogen source. The optimum concentration of NaCl for both cell growth and enzyme activity was 2.5%. The agarase was purified by DEAE-cellulose and hydroxyapatite column chro-matograpy. The purified agarase showed a single protein band upon sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE) and its molecular weight was estimated to be 50 KDa. The optimal temperature and pH for the enzyme activity were 28℃ and 7.2, respectively. The agarase was stable at pH 6.5 - 8 and 22 - 37℃. The agarase activity was notably inhibited by EDTA, Mn2+, Hg2+, Fe2+ and slightly activated by Na+ and Ba2+.

Metal balls are commonly used in mechanical elements and systems including bearings. If there is a defect in a metal ball, it can cause a serious machine failure. By this reason every balls produced are required to be inspected, and the inspection is usually done by human eyes. However, the inspection by human eyes is always with the risk of mistakes, and a need to automate the inspection process is arisen. This paper describes a design of an automatic inspection system for detecting defects on ball surface. A machine vision system is used, and design process and techniques are described in detail. 강구는 베어링을 비롯한 기계 요소 및 장치에서 널리 사용되는 부품이다. 만약 강구에 결함이 있을 시, 이를 사용하는 기계에서 치명적인 결함이 초래될 수 있다. 따라서 제조된 강구에 대해서는 전량검사가 요구되고 있고, 검사과정은 사람의 육안에 의한 검사가 주를 이루고 있다. 그런데 사람에 의한 검사에는 항상 실수의 가능성이 있으므로, 이를 자동화하는 것이 필요하다. 본 논문에서는 강구의 표면 결함을 자동적으로 검사할 수 있는 장치를 설계한다. 기계시각 장치가 사용되었고, 설계에 따른 구체적 절차와 기술들이 서술된다.

A new balloon dissector, a modification of a Foley catheter, was devised and it can be used either as a dissector or a tissue expander. Since most operating time was spent in balloon manipulation (inflation/deflation), the duct for saline injection was made to be wider than the Foley catheter. As a result, the balloon could be inflated faster than before. In order to reduce the scar at the donor site, harvest of the sural nerve using endoscopic technique is currently applied, but utilization of this method is technically difficult and requires a long operating time. For these reasons, new our method of using a balloon dissector was devised. The balloon dissector can also be used for immediate intraoperative tissue expansion for the reconstruction of small skin defects without distortion. We have found that the advantages of using the new balloon dissector include a reduction in operating time, preservation of the perforating vessels, and primary closure with less tension. In addition, this simple and inexpensive instrument is cost-beneficial to patients.
