This is a case report about effect of syeom pharmacopuncture, bee venom and autohemo-seperated regeneration pharmacopuncture(ASRP) for acute traumatic subdeltoid bursitis with partial tear of subscapularis tendon, which was diagnosed by symptoms and MRI(Magnetic resonance imaging) and caused by bongchuna treatment. We evaluated the patient using Visual Analogue Scale(VAS) every two or four days and range of movement(ROM), physical examination of shoulder about one per ten days and observed improvement with reexamination by ultrasonography and MRI as well. Pharmacopuncture rapidly reduced pain and improved range of motion and function of shoulder in patients with acute sub-deltoid bursitis even though it was severe symptom. Our result suggest that autohemo-seperated regeneration pharmacopuncture might be effective in regenerating the tear of soft tissue such as subscapularis tendon.

The aim of this study was to evaluate the feasibilities on national recycling goal upto 40% in 2002 or more in the future. Sampling survey, Including waste generation rates, seperated recyclables and collection forces, covered households of 16,199 units, work places of 90 units and road length of 159km in Seoul. Survey results were used to calculate amounts of solid waste and recyclables according to physical properties, policy oriented measures, generator sand collection forces. This study founded followings ; Seoul's solid waste totaled 11,098ton/day, about 45% of which were recyclables and supposed to maximun level for recycling. Therefore, national goal for recycling proved to be attainable At this time,71.4% of recyclables was seperated by generators, and to stimulate the seperation activities of recyclables, endeavor of establishments, which seperated 65.6% of their recyclables, will be needed more than one of residence, which did 87.4% of their recyclables. Private forces collected 86.6% of recyclables seperated by generators, and have collection potentials equivalent to all recyclables generated in Seoul. But some incetives should be introduced to encourage private forces' activities, because values of recyclables to be collected in the future are lower than that did now.

This paper represents an accurate evaluation method in the eigenvalue analysis of the synchronous machine which has the characteristics of seperated saturation and cross-magnetized one. The cross-magnetizing effect is included in the reactance and state matrix of the machine. And the machine with excitation system is simulated in the cases of those two saturations. The simulation results show the existence of the differences between the seperated saturation and the cross-magnetized one in the analysis of power system.

들깨에 존재하는 brassinosteroid 활성물질을 탐색하기 위하여 미숙종자를 MeOH로 추출하고, 이 추출물을 rice inclination test를 지표로, 용매 분획, silica gel adsorption chromatography, Sephadex LH-20 chromatography, charcoal adsorption chromatography, Bondesil chromatography 등의 수법으로 brassinosteroid 활성물질을 정제한 다음, silica gel 흡착 chromatography로 활성성분을 분리하고, 각 활성획분에 대해 HPLC에 의해 활성본체를 구명한 결과, main brassinosteroid로 castasterone이 그리고 minor brassinosteroid로 homodolicholide가 최초로 동정되었다. 들깨에 함유된 brassinosteroid의 함량은 brassinolide로 환산하여 생체중량 g당 $0.5{\sim}0.8\;ng$ 수준이었다.

본 연구는 1991년 2월부터 1992년 7월까지 우리 나라 해역에 분포하는 오징어에 대해 외투장 조성과 생식소 발달 상태에 의해 하계군, 추계군 및 동계군과 같이 세 군으로 분리하였다. 오징어의 크기와 성숙에 관한 축적된 지견에 근거하여 외투장 조성에서 군을 분리시, 채집시의 외투장과 생식소 발달 상태를 오징어의 크기와 성숙에 관한 연구자의 축적된 지견과 비교하여 분리한 군과 Tanaka(1956)의 방법을 적용하여 분리한 군이 가장 잘 일치하는 것을 알 수 있었다. 그러나 Bhattacharya(1967)와 Cassie (1954)의 방법에 의해 분리된 군과는 잘 일치하지 않았다.

Visible light communication technology is being studied and developed in various ways due to advantages such as high transmission speed, excellent positioning and higher security. However, existing visible light communication systems have difficulties in entering the market because they use special transmitters and receivers. We will overcome the difficulty if we develope a VLC system that uses a conventional LED light as a transmitter and a smartphone camera as a receiver. What matters is that LED lights include a scatter filter to prevent glareness for human eyes, but the existing VLC(Visual Light Communication) method can not be applied. In this paper, we propose a method to encode data with On / Off patterns of LEDs in the lighting with $M{\times}N$ LEDs. We defined parameters like L-off-able and K-seperated to facilitate the recognition of On / Off patterns in the diffused Lights. We conducted experiments using an LED lighting and smart phones to determine the parameter values. Also, the maximum transmission rate of our encoding technique is mathematically presented. Our encoding scheme can be applied to indoor and outdoor positioning applications or settlement of commercial transactions.

In this study quantifying techniques of ELF magnetic fields arising from currunt carrying indoor-conductor are proposed. These techniques can be applied to line-conductor with finite length and any configuration. Since each component of magnetic field in rectangular axes system is seperated, the resultant magnetic field can be caculated for multi-conductor system through these techniques.

Different bacteria wwere seperated from saliva and teeth of cariogenic patients and identified by a variety of morphological and biochemical tests. Extracts of green tea strongly inhibited Escherichia coli, Streptococcus salivarius and Streptococcus mutans. The antibacterial effect of green and black tea extracts were compared with those of amoxicillin, cephradine and eugenol.

The purpose of this study was to evaluate their mechanical properties after laser-welding or soldering of precious and non-precious dental alloys. For this study, 30 Co-Cr alloy specimens, 15 gold alloy specimens, 15 palladium alloy specimens were casted and seperated on the middle area. 15 sperated Co-Cr specimens and 15 seperated gold alloy specimens were laser welded (GW Group). 15 sperated Co-Cr specimens and 15 sperated gold alloy specimens were soldered by coventional soldering method (GS Group). 15 sperated Co-Cr specimens and 15 seperated palladium alloy specimens were laser welded (PW Group). 15 sperated Co-Cr specimens and 15 sperated palladium alloy specimens were soldered by coventional soldering method (PS Group). Tensile strength, 0.2% yield strength, % elongation were recorded in nine specimens of each group. Bending strength were record in six specimens of each group. These data for four groups were subjected to a two-way analysis of variance(ANOVA). The fracture locations, fractured surfaces were examined by SEM(scanning electron microscope). The results were as following: 1) In the same alloy combination, the tensile strength and 0.2% yield strength and of the laser welded group with same metal combination were significantly less than soldered groups(p<0.05). 2) In the combination of Co-Cr/Palladium, the bending strength of laser welded group were significantly less than that of soldered groups(p<0.05). In the combination of Co-Cr/Gold, the bending strength of laser welded group were significantly higher than that of soldered groups(p<0.05). 3) In the same method of joint, the tensile strength and 0.2% yield strength and bending strength of the Co-Cr/gold were significantly higher than Co-Cr/palladium(p<0.05). 4) There was no significantly statistical difference between each group in the % elongation(p>0.05). 5) The fracture of the laser welded specimens occured in the welding area and a large void was observed at the center of the fracture surface. 6) The fracture of the soldered specimens occured also inthe soldered area and many porpsities were showed at the fracture sites.
