Objectives : To observe the effect of acupuncture treatment on Digital Infrared Thermographic Imaging(DITI) in frozen shoulder patients. Methods : 17 voluntary patients received acupuncture treatment on LI15, TE14, GB21 and Master Dong's acupuncture points, Shin-gwanand Gyun-joong, twice a week for 4 weeks. The patients were instructed to practice self exercise during their daily lives. Evaluations were made before treatment, after 1 week of treatment, after 2 weeks, 3 weeks and after 4 weeks of treatment. Constant Shoulder Assessment(CSA), Shoulder Pain and Disability Index(SPADI), Range of Motion(ROM) and the patient's satisfaction concerning the treatment was measured by Visual Analogue Scale(VAS). DITI was measured before treatment and after 4weeks of treatment. The obtained data was analyzed. Results : CSA, SPADI, VAS, adduction and extension showed significant(p<0.05) improvement. Abduction and flexion both improved after 4 weeks of treatment, but the improvement was statistically insignificant(p>0.05). DITI showed improvement but the improvement was insignificant(p>0.05). Conclusion : 4 weeks of acupuncture treatment significantly improved CSA, SPADI, VAS, adduction and extension in frozen shoulder patients(p<0.05). The improvement of abduction and flexion after 4 weeks of acupuncture treatment was insignificant(p>0.05). DITI results improved after 4 weeks of acupuncture treatment. But the change of thermal difference was insignificant(p>0.05).

This experiment was carried to determine optimum condition for the japanese apricot wine (nonfermentation) processing. The chemical constituent was analyzed according to different addable sugar, diluted ethanol and stored days. The results in chemical analysis were summarized as follows: 1. The pH and S.G was observed little difference. 2. The total acid was decreased by the after ninety stored days. 3. The more the sugar added, the higher the degree of sugar was observed, and the higher the concentration of diluted ethanol was , the higher the degree of sugar was observed but the longer the stored days were, the less the degree of sugar was. 4. The more the sugar added, the less the degree of ethanol was observed, and the higher the concentration of diluted ethanol, the higher the degree of ethanol was observed, also the longer the stored days were, the less the degree of ethanol was. 5. According to the results of chemical constituents in this experiment, the proper conditions of japanese apricor wine were 20∼30% addable sugar, 30∼40% diluted ethanol, and 90∼120 stored days at the room temperature.

To investigate the inhibitory effect of soybean and Korean traditional fermented soybean products on the chemically induced mutagenesis, we extracted soybean, Kanjang, Doenjang, Kochujang, and Chonkukjang with water, methanol and hexane. Inhibitory effect of extracts was assayed by the SOS chromotest using Escherichia coli PQ37 as a test strain. 4-nitroquinoline-1-oxide(4NQO), N-methyl-N'-nitro-N-nitrosoguanidine(MNNG), and aflatoxin B_1(AFB_1) were used as mutagens. Methanol extracts showed relatively higher inhibitory effect than water and hexane extracts. Methanol extracts of soybea, Doenjang, Kochujang, and Chongkukjang showed inhibitory effect of 68.4, 96.3, 17.5, and 100.9%, against MNNG, and 28.6, 109.1, 41.3, and 101.8% against AFB_1., respectively. Doenjang methanol extract showed inhibitory effect of 51.0, 96.3, and 109.1% against 4NQO, MNNG, and AFB_1. Inhibitory effect of heat-treated Doenjang and Chongkukjang methanol extracts on the mutagenicity of MNNG and AFB_1 was remained over 95% of the inhibitory effect of heat-untreated extracts, demonstrating the heat stability of the potent antimutagenic activity.

인터넷의 급작스러운 성장은 기업환경에 지대한 변화를 야기하였으며 이로 인하여 실물경제의 변화와 산업가치사슬의 개념을 재정립하게 되었다. e-비즈니스는 매우 중요시 되어 각 국가 및 기업에서도 디지털경제시대에 순응하지 못하면 경쟁력을 상실할 것으로 예상하고 있다. 이와 같은 이유로 소규모 기업을 위한 전략적 관점에서의 수익모델을 구현하고자 한다. The tremendous growth of the internet has resulted in significant changes in business environment. Internet has brought significant changes in the physical economics of the business and has led to a redefinition of industry value chain. E-business has become so important that countries and firms unprepared for new trend lose competitive advantages in coming country of digital economy. From this reasons, we will be propose this model of the strategic approach for the small business.

A rapid and simple test to distinguish halloysite from kaolinite in mineral mixtures has been developed based on differences in the rate and extent of formamide intercalation. The results of quantitative analysis by formamide intercalation reaction GEC contained 90% of kaolin minerals, GEC contained of 86% of halloysite and GYK contained of 59% kaolinite. The extent of formamide intercalation by kaolinite was likely influenced by sample crystallinity.

효율적 영역 기반 부호화를 위한 인간 시각 특성에 기반한 계층적 영상 분할

송근원,정광민,도경훈 東西大學校 1998 동서논문집 Vol.4 No.-

본 논문에서는 주관적 화질 및 객관적 화질을 유지하면서 영역 기반 초저속 부호화에서 병목 현상을 유발하는 과다한 윤곽선 정보를 효과적으로 줄일 수 있으며, 또한 각 계층에서의 전송 정보량를 조절할 수 있는 계층적 영상 분할 알고리즘을 제안한다. 제안한 알고리즘은 각 계층에서 수리 형태학에 기반한 계층적 영상 분할과 인간 시각 시스템(HVS)특성을 고려한 영역 병합으로 구성된다. 계층적 영상 분할은 3계층으로 이루어져 있으며, 영상 분할 수 인간 시각이 구분할 수 없는 두 인접 영역을 병합한다. 이때 인간 시각 시스템 특성에 기반하여 병합 순서를 결정하는 병합 우선 순휘 함수(MPF)를 제한하여 영역 병합을 수행한다. 실험을 통하여 제안한 알고리즘은 기존의 알고리즘보다 PSNR은 평균 0.14dB 낮으나, 윤곽선 정보량은 30% 줄일 수 있었으며, 또한 각 계층에서 전송 정보량을 조절할 수 있는 적응성이 있는 영상 분할 구조임을 알 수 있었다. In this paper, a new hierarchical image segmentation algorithm based on human visual system(HVS) characteristic, which can efficiently reduce information quantity to be transmitted without the degradation of the subjective and objective image quality, and which is suitable for region-based very low bit coding because it can control information quantity to be transmitted, is proposed. It consists of image segmentation based on mathematical morphology and region merging considering HVS characteristic for the pairs of two adjacent regions at each level of the hierarchy. Image segmentation is composed of 3-level hierarchical structure and in the region merging structure of each level, we extract the pairs of two adjacent regions which human vision can't discriminate, and then merge them. Since the proposed region merging method selects two neighbor regions to be merged and performs region merging according to merging order based on HVS characteristics, it can efficiently improve bottleneck problem caused by excessive contour information at region-based very low bit rate coding. In experimental results, though the PSNR by the proposed algorithm is about 0.14dB lower than that of conventional method, the subjective image quality is almost the same and the contour information to be transmitted is reduced as much as 23.9% on the average.

SOI(Silicon On Insulator)기술은 MOS(Metal-Oxide Semiconductor), CMOS(Complementary MOS)등의 전자집적회로 제조시 소자의 고속화, 고집적화, 저전력화, 발열 특성의 향상 등의 효과를 기대할 수 있다. 간략하게 Bonded SOI웨이퍼의 제조를 설명하면 SiO₂를 성장시킨 웨이퍼와 경면 가공한 다른 웨이퍼를 접합하여 열처리 등 후공정을 행한 후 한쪽 웨이퍼를 원하는 두께만큼 박막으로 가공한다. 본 연구에서는 기본적인 Bonded SOI 웨이퍼의 제조 공정 기술을 획득하고, 이를 통해 두께 3㎛ 이하, 표면거칠기 5Å이하의 상부 실리콘 박막을 가공하였다. SOI(Silicon On Insulator) technology is many advantages in the fabrication of MOS(Metal-Oxide Semiconductor) and CMOS(Complementary MOS) structures. These include high speed, lower dynamic power consumption, greater packing density, increased radiation tolearence et al. In the smiplest form of bonded SOI wafer manufacturing, creating, a bonded SOI structure involves oxidizing at least one of the mirror polished silicon surfaces, cleaning the oxidized surface and the surface of the layer to which it will be bonded, bringing the two cleanded surfaces together in close physical proximity, allowing the subsequent room temperature bonding to proceed to completion, and then following this room temperature joining with some form of heat treatment step, and device wafer is thinned to the target thickness. In this paper, The process of Bonded SOI wafer manufacturing is described briefly, and we made an attempt to manufacture the Bonded SOI safer that Si layer thickness is below 3㎛ and average roughness is below 5Å.
