We report two cases of murine typhus diagnosed by indirect immunofluorescent test. The patients showed cardinal symptoms and signs such as fever and chill, general myalgia, intractable headache and typical rash. Laboratory values and histopathologic findings were compatible with murine typhus. The oral administration of doxycycline improved dramatically the clinical manifestations of the two CCLSPS.

Forty patients(9 male and 31 female) with tsutsugamushi disease were evaluated clinically. The diagnosis of tsutsugamushi disease was confirmed by indirect immunofluoresent test or isolation of causative agent. More than 77% of patients were over 40 years of age. After the incubation period(5 to 13 days, average 8 days) symptoms developed suddenly. The frequent symtoms were fever(100%), chill(100%), headache(100%), rnalaise(97%), and myalgia(95%). On physical exammination the rash, eschar, and lymphadenopathy were found in 97%, 82%, and 67% respectively. Eschar was observed in the trunk, especially axillary, abdominal and inguinal area. Serum transarninase(SGOT snd SGPT) was elevated(89 and 87%). Urinalysis revealed proteinuria in 35%(12/34) and hematuria in 19%(7/36). Chest roentgram and ECG demonstrated abnormalities in 39%(14/36) and 73%(26/36) respectively, The treatment with doxycycline was very effective in all cases.

We report a case of staphylococcal septicemia with skin lesions characteristic of septic emboli in a 55-year-old man. Examination of the skin revealed small pustules surrounded by wide ring of erythema on the trunk and extremities. Histopathologic examination of a pustule showed subcorneal pustule and Gram positive septic emboli within blood vessels. There were neutrophilic infiltration and numerous extravasated erythrocytes within dermis. Staphylococcus aureus was isolated on the bacterial culture of blood and small pustules, He was treated with cloxacillin, but died due to respiratory distress syndrome.

본 논문에서는 무선 이동통신환경에서 다양한 멀티미디어 데이터에 대한 정보제공자와 사용자를 위한 데이터 보안을 위한 시스템을 제안한다. 무선 이동통신환경은 편리성과 유용성으로 사용자가 매우 많으며 대역폭의 증가로 인한 멀티미디어 데이터의 사용량이 증가 했지만 데이터의 보안에 대한 부분은 부족한 부분이 많아 저작권이 보호되지 못하고 있다. 따라서 본 논문에서는 부적합 사용자에게는 멀티미디어 컨텐츠의 내용을 숨기고 적절한 사용자에게는 정확한 데이터를 제공할 수 있는 컨텐츠 보호시스템에 대한 내용을 제안한다. 정보제공자와 사용자는 상호 신뢰성을 확립할 수 있으며 이동단말기와 PC의 특성을 이용한 간단한 인증과정을 통해 쉽고 편리하게 원하는 컨텐츠를 사용할 수 있다. In this article, the protection system on wireless mobile communication circumstance for the information providers and the users is recommended. Because of its usefulness and convenience, the users of the wireless mobile communication are growing explosively. However, the function of protecting data systems is not secured enough so, personal information may disclose to the outside, regardless of one's intention. Therefore, the contents protection system, which can provide information to the user or hide it depending on user's identity, is suggested. If so, the providers and the users can trust each other for interchanging information, also the users may safely use contents menu whatever they want by doing simple certification process.

This paper is a feasibility study on the calculation of operating cost in regards to the overall operation following the completion of a number of LRT lines currently in progress. Owing to the absence of operating experience in driveless LRT system at home, the difficulties lie in the assumption of the optimal operating budget applying domestic real situation. Nevertheless, with 34 years of accumulated operating experience in heavy rail transit system, Seoul Metro, the nation"s biggest urban rail transit operator, performs O&M consultancy services for several on-going projects along with every effort to acquire know-how where the appropriateness of the cost estimation as a required deliverable is reviewed and a more efficient way is provided. The main focus of this study is to seek a method to calculate the optimal amount of operating expenses as well as a cost-effective alternative for possible weaknesses from the standpoint of the operator. The body of this paper discusses the five issues such as personnel cost, overhead, maintenance cost, additional purchase price, alternative investment fee from a more macroscopic point of view, and the conclusion deals with the adequacy of the reason for selection of institutions with various operating know-how.

We report herein a. case of angio-Behqets syndrome, arterial occlusion type in a 31 year-old male. He had a history of scrotal ulceration, frequent oral ulceration and ocular pain with decreased visual acuity. About 8 months ago, moderately dull pain developed on the volar aspect of left index finger. Subsequently, a bean sized bluish patch developed on the previous painful area and on the ipsilateral thumb tip. Subungual splinter hemorrhages developed on the distal portions of left thumb and index finger nails at the same time. The result of saline puncture test showed the positive reaction in both intradermal and subeutaneous injections. The hrachial angiography showed an obliteration of digital artery at the second proxirnal phalanx of ulnar side.

N-(p-Coumaroyl)serotonin과 N-Feruloylserotonin은 홍화씨에서 유래하는 특이적인 세로토닌유도체로 주로 식물이 병원균을 방어하기 위해서 만들어내는 hydroxycinnamic acid amides계 물질이다. 본 연구에서는 N-(p-Coumaroyl) serotonin과 N-Feruloylserotonin이 지방전구세포의 지방분화에 미치는 영향을 oil-red O염색과 triglyceride 양 측정, GPDH 활성 측정 등을 통해 알아보았고, 그 결과 두 물질 모두 유의적으로 지방세포분화를 억제함을 관찰하였다. 효능비교물질로 세로토닌을 처리했을 때 세로토닌 자체로는 지방분화에 유의미한 효과는 관찰되지 않았다. N-(p-Coumaroyl) serotonin과 N-Feruloylserotonin은 또한 우수한 항산화능을 보여주었다. 이러한 결과를 통해, N-(p-Coumaroyl)serotonin과 N-Feruloylserotonin이 지방세포분화억제를 통한 항비만 소재로서의 가능성을 확인하였다. N-feruloylserotonin (FS) and N-(pcoumaroyl) serotonin (CS), serotonin derivatives, which have been isolated as major and unique phenolics of safflower seed extract (SSE), are member of hydroxycinnamic acid amides and are implicated in the defense against pathogen infection and insect feeding. In this study, we evaluate inhibitory effects of N-(p-Coumaroyl)serotonin and N-Feruloylserotonin on adipogenesis using oil-red O staining, triglyceride and GPDH activity. we found that while serotonin itself did not suppress differentiation of preadipocytes into adipocytes, N-(p-Coumaroyl)serotonin and N-Feruloylserotonin inhibited the differentiation of preadipocytes into adipocytes in a concentration-dependent manner. In addition, they showed antioxidant effects in DPPH assay. Taken together, these results show that N-feruloylserotonin (FS) and N-(pcoumaroyl) serotonin (CS) suppress differentiation of preadipocytes, suggesting the possibility that these serotonin derivatives can be utilized as an anti-obesity agent.
