In general cases, the conventional internet connected to a terrestrial network is transmit too large medical images. To overcome this low speed transmitting rate problem of the internet, we have studied about an image division communication system as a fast telemedicine system. The image division communication system was 5-10 times faster than the conventional terrestrial internet link. Also we have developed a Web-based telemedicine system that can access every permitted server of hospitals via the internet. Visual Basic and C++, ASP programming techniques were used to make our system and it can access and retrieve medical information and image through only public web browse such as internet explorer without additional specific tools. To increase the transmitting speed of our telemedicine system, JPEG method was used. In conclusion, we were able to develop a fast and public telemedicine system using the proposed image division communication system and Web technology. image division communication system technology increased the speed of the conventional internet and Web technology extended the scope of use for telemedicine system from intrahospital to public use.

Objectives : To figure out the factors related to the failure of primary pulmonary tuberculosis(Tb) treatment and to enhance the efficiency of the treatment. Methods and Materials : The subjects were 137 Tb patients composed of the two groups; 44 failure cases and 93 success cases who admitted in National Masan Tuberculosis Hospital during 2001. The failure means no improvement with the standard short term regimen of INH and RFP. Patients' informations were gathered through medical records and face-to-face interview survey, and, the data were analyzed with SPSS(ver 10.0). Results : Mean age of the subjects were 47.6 years. Most cases were diagnosed at clinics or hospitals at first, due to the symptoms. No difference in smoking and alcohol habits between the two groups. The cases who got the informations about the whole process of treatment, and following regular regimens were more in the success group. The proportion of multi-drug resistance to the regular primary Tb regimen was higher in the failure group 8 cases out of 25 detectable failure cases. 0 case among 46 successful cases. And the four regular regimen(INH, RFP, EMB, PZA) was popular type of the resistance. In chest X-ray, multiply involved lesion(≥ two lobes), atelectasis and pleurisy were more frequent in the failure group. Conclusion : The major factors that enhance the efficiency of Tb treatment were the informations and compliance. Enough explanation about the whole process would be essential during Tb treatment, and, in case of MDR-Tb, susceptible regimen and surgical therapy should be considered.

The purpose of this study was to investigate the patterns of the health related variables, and physical characteristics and physical fitness of the elderly people in order to provide a exercise program. The data about the health related variables were collected through the personal interview, and the data about physical charateristics and physical fitness (height, weight, % body fat, blood pressure, pulse rate, grip stength, trunk flexion, side step test, 2 min, harvard step test) of 373 elderly people living Seoul and kyungkee area were collected. The conclusions of this study can be summarized as follow; 1. The test results about smoking, drinking, sleeping and self-evaluation of health revealed that the elderly people have self-confidence about their health. 2. Not many elderly people participate the proper exercise program even though they recognize the need of exercise. 3. The results showed that the elderly people do not pay much attention to the intensity of the exercise. 4. Muscle strength training for leg and the lower back and cardio-vascular endurance training was recommended to reduce the risk of varius problems caused by aging. 5. A exercise program was suggested for the elderly people.

무증상으로 발견된 담낭-담관 누공을 동반한 Mirizzi 증후군 1예

홍진희,전태주,서지영,서동대,오태훈,신원창,최원충,신은아,김기환 인제대학교 2009 仁濟醫學 Vol.30 No.-

Mirizzi's syndrome is a rare complication of the gallstone disease, characterized by narrowing of the common bile duct (CBD) due to chronic extrinsic compression of an impacted gallstone in the cystic duct or the neck of the gallbladder. The impacted gallstone may erode into the bile duct, causing cholecystocholedochal fistula. The patients generally have history of repeated attacks of jaundice and abdominal pain. But there is no report about asymptomatic Mirizzi syndrome with cholecystocholedochal fistula which were found incidentally. So herein we present our clinical experience with a case of asymptomatic Mirizzi syndrome with cholecystocholedochal fistula in a young female.

Metronidazole은 아메바병 등과 무산소성 염증을 치료하기 위하여 사용되는 약물이나 드물게 그 부작용으로 신경학적 이상을 초래할 수 있다. 저자들은 metronidazole의 부작용에 의한 뇌병증과 말초신경병증를 야기한 증례를 경험하여 자기공명영상소견및 문헌고찰과 함께 보고한다. 병변은 T2 강조영상 및 액체감쇠역전회복 영상에서 소뇌의 백질에 부종이나 종괴 효과를 동반하지 않는 양측성, 대칭성 병변을 보였고 약제 투여의 중단으로 임상증상과 병변은 호전되었다. Metronidazole is used for treatment of amebiasis, anaerobic infection and many other illness, but it produces a number of neurologic side effects. We report a case of metronidazole induced encephalopathy and peripheral neuropathy with MRI findings. Both T2-weighted and FLAIR images revealed bilateral and symmetrical lesions in the cerebellar white matter without surrounding edema and mass effect. With discontinuity of metronidazole, the lesions on MRI and clinical symptorms were completely improved.

Current influenza vaccines are produced in embryonated chicken eggs. However, egg-based vaccines have various problems. To address these problems, recombinant protein vaccines have been developed as new vaccine candidates. Unfortunately, recombinant proteins frequently encounter aggregation and low stability during their biogenesis. It has been previously demonstrated that recombinantly expressed proteins can be greatly stabilized with high solubility by fusing stabilizing peptide (SP) derived from the C-terminal acidic tail of human synuclein (ATS). To investigate whether SP fusion proteins can induce protective immunity in mice, we produced influenza HA and SP fusion protein using a baculovirus expression system. In in vitro tests, SP-fused recombinant HA1 (SP-rHA1) was shown to be more stable than recombinant HA1 (rHA1). Mice were immunized intramuscularly with baculovirus-expressed rHA1 protein or SP-rHA1 protein (2 μg/mouse) formulated with aluminum hydroxide. Antibody responses were determined by ELISA and hemagglutination inhibition assay. We observed that SP-rHA1 immunization elicited HA-specific antibody responses that were comparable to rHA1 immunization. These results indicate that fusion of SP to rHA1 does not negatively affect the immunogenicity of the vaccine candidate. Therefore, it is possible to apply SP fusion technology to develop stable recombinant protein vaccines with high solubility.

본 연구에서는 에폭시 나노복합재료의 수분 흡수, 열적 안정성 및 기계적 특성에 대한 소수성 실리카의 효과에 대해 고찰하였고, 에폭시 수지의 필러로는 디메틸디크로로실란에 의해 소수성으로 처리된 실리카를 사용하였다. 실험결과, 실리카는 실란 커플링제의 첨가후 용융혼합법에 의하여 에폭시 수지내에서 균일하게 분산되었으며, 나노복합체의 수분 흡수율은 소수성으로 처리된 실리카의 함량 증가와 함께 감소하는 것을 확인하였다. 열분해 온도, 유리전이온도, 그리고 열팽창 계수를 통한 나노복합재료의 열안정성은 실리카의 첨가와 함께 향상되는 것을 확인하였다. 또한, 인장강도 및 탄성율을 통한 나노복합재료의 기계적 특성은 실리카 함량 증가와 함께 증가하였고, 이는 에폭시 수지내에 고르게 분산된 실리카와 에폭시 수지 간의 강한 물리적 상호작용에 기인하는 것으로 판단된다. In this work, the effect of hydrophobic treated silica on the water absorption, thermal stabilities, and mechanical properties of the epoxy nanocomposites were investigated as a function of the silica content. As filler, fumed silica treated by dimethyldichlorosilane was used. It was found that the silica was well dispersed in the epoxy resins by the melt-mixing method with the addition of a silane coupling agent. The water absorption of the nanocomposites decreased with an increase of the silica content due to the effect of hydrophobic treated silica. The thermal properties, such as thermal degradation temperature, glass transition temperature (Tg), and coefficient of thermal expansion (CTE), of the nanocomposites were improved by the addition of silica. Furthermore, the mechanical properties of the nanocomposites, that is, the tensile strength and modulus, were enhanced with increasing silica content. This was attributed to the physically strong interaction between silica and epoxy resins.

Despite of current research on motivation in the field of casino, little research has been conducted to identify motivations of inbound tourists to casinos and then segment them with distinct subgroups for practical marketing strategies. In this respect, this study aimed to identify the underlying dimensions of motivations for inbound casino visitors, using a factor analysis, segment the inbound casino market, using a clustering analysis based on derived motivation factors, and examine any differences between market segments with respect to socio-demographic and behavioral variables using cross-tabulation analysis. To this end, a survey was conducted to inbound tourists who played casino gambling at foreign visitors` casino in metropolitan Seoul. The factor analysis delineated five dimensions of casino motivations from 27 items of motives: Novelty, Challenge, Escape, Socialization, and Winning for Money. The results of cluster analysis indicate that two distinctive segments were identified: Moderate and Aggressive Casino Visitors. These two segments were significantly different with respect to nationality, educational level, marital status, age, purpose of visit, frequency of visit to Korea, companion, favorite games, and experience in international casino gambling. Based on the results of this study, marketing implications for casino managers were provided in the conclusion section.
