본 연구는 최근 기업이나 사회적으로 중요한 관심의 대상이 되고 있는 온라인 커뮤니티에 대한 특성과 오프라인상의 커뮤니티를 심층면접을 통해 비교, 분석하기 위한 탐색적 연구이다. 연구의 목적을 요약하면, 우선 기존의 커뮤니티와 관련된 문헌과 온라인 커뮤니티 관련 연구 동향을 검토한다. 둘째, 전통적인 커뮤니티와 온라인 커뮤니티의 비교를 위해 심층면접법을 실시하여 온라인 커뮤니티 특성에 대한 이론적 틀을 제시한다. 셋째, 심층면접의 결과를 토대로 하여 관계마케팅 뿐만 아니라, 온라인 공동체 의식과 관련된 향후 연구문제를 제안한다. 연구결과를 통해 전통적인 커뮤니티와 온라인 커뮤니티와의 유사점과 차이점이 구분되었으며, 이를 바탕으로 향후 연구과제를 제안하고 있다. 따라서 본 연구는 온라인 커뮤니티가 점차 증가되고 있는 시점에서 온라인 커뮤니티에 대한 보다 심층적인 연구방향을 제시해 줄 수 있는 기회를 제공할 것이다.

Disposal of a homicide victim by dismemberment is rare, but individual cases are on record in most major medicolegal departments. Recognition of postmortem mutilation may be of importance in the interpretation of certain murders committed by sexual perverts and other mentally deranged individuals and sometimes performed for the sole reason of easier disposal of the body. Postmortem dismemberment is usually readily recognizable as such; The edges of the injuries are dry and lack evidence of bleeding. The joints may be disarticulated without fracture, or the use of an axe or saw may be evident from examination of bones. Parallel horizontal or oblique furrows in the bone surface are caused by skipping of the saw prior to establishing depth. Such patterns on the bone may assist in identifying the particular saw involved. So we report 25 dismembered corpses that autopsied in National Institute of Scientific Investigation. This paper can help in attempting to establish not only the first criminal investigation steps but also the medicolegal approach methods in unidentified and dismembered deaths.

The principal manifestation of poisoning induced by the alkaline substance is a corrosive effects in tissues. The alkalies combine with protein and fat of the tissue, causing deep penetrating injury and liquefactive necrosis of the organs. Liquid lye is the most frequently ingested form of corrosive agents and causes most of the deaths associated with corrosive agent ingestion. We have experienced 5 fatal cases which were accidentally administered liquid lye as soap-saline enema in the hospital during 30 days. the 3 cases of them were autopsied at this institute. At autopsy, the digestive tract including rectum, colon and small intestine revealed hemorrhagic necrosis with multiple area of perforation. Because these were the first proved cases that the liquid lye was used as enema solution, we report here.

Nortropinone 유도체로부터 Nortropane Spirohydantoin 유도체의 합성
정대일,박유미,박종훈,김윤영,정두희,김인식 東亞大學校 1998 東亞論叢 Vol.35 No.-
The nortropinones 11 (tropinone lla, N-isopropylnortropinone 11b, N-Carbethoxynortropinone 11c, N-furfurylnortropinone 11d, N-(p-methoxyphenyl)nortropinone 11e) were respectively synthesized by the treatment of acetonedicarboxylic acid 8 with, 2, 5-dimethoxytetrahydrofurane 9 in various amines 10 (methylamine 10a, N-isopropylamine 10b, ethylcarbamate 10c, furfurylamine 10d, p-anisidine 10e). The nortropane spirohydantoins 14 (tropane spirohydanttoin 14a, N-isopropylnortropane spirohydantoin 14b, N-Carbethoxynortropane spirohydantoin 14c, N-furfurylnortropane spirohydantion 14d, n_(p-methoxyphenyl) nortropane spirohydantoin 14e) were respectively synthesized by the treatment of synthesized nortropinones 11 (tropinone 11a 54%, N-isopropylnortropinone 11b 50%, N-Carbethoxynortropinone 11c 58%, N-furfurylnortropinone 11d 31%, N-(p-methoxyphenyl) nortropinone 11e, 70%) with potassium cyanide 12, ammonium carbonate 13.

Benzodiazepinone과 1,5-Benzodiazepine 유도체의 합성 연구
정대일,이용균,박유미,최태원,정일수,김인식,김윤영 東亞大學校 1997 東亞論叢 Vol.34 No.-
The reaction of o-phenylenediamine 5 with acrylic acid 11 in the presencce of P₂O5+H₃PO₄afforded benzodiazepinone 13 and pyridobenzodiazepinono 17. The reactions of o-phenylenediamine 5 with acrylic acid 11 in the presence of PPA or SiO₂afforded only benzodiazepinone 13. But the reaction of O-phenylenediamine 5 with acrylic acid 11 in the presence of acetonedicarboxylic acid 18 or acetonedicarboxylic acid 18 and PPA or acetonedicarboxylic acid 18 and SiO₂was respectively synthesized 2,4,4,-trimethyI-3H-5-hydro-1.5-benzodi-azepine 23 as new cyclic imine compound. We propose that formation of 2-(2`-imine)propyI-N-isopropylidene aniline proceed though 2-amino, N-isopropylidene aniline intermediate C and 2-(N-a-methylethyI) amino, N-isopropylidene aniline intermediate G. The reaction of o-phenylenediamine 5 with acetonedicarboxylic acid 18 in the presence of PPA or SiO₂or HCI gave 2,4,4-trimethyI-3H-5-hydro-1,5-benzodiazepine 23. Using acetone 19 instead of acetonedicarboxylic acid 18, the reaction of o-phenylenediamine 5 in the presence of PPA or SiO₂or acrylic acid 11 was synthesized 2,4,4-trimethyI-3H-5-hydro-1,5-benzodiazepine 23 as same product. And also the reaction of o-phenylenediamine 5 with acetone 19 and acrylic 11 in the presence of PPA or SiO₂was obtained 2,4,4-trimethyI-3H-5-hydro-1,5-benzodiazepine 23. In case of acetophenone 21 in stead of acceton 19, the reaction of o-phenylenediamine 5 in presence of PPA or SiO₂at 40~45℃ were obtained 2,4-diphenyI-4methyI-3H-5-hydro-1,5-benzodiazepine 24. The reaction of o-phenylenediamine 5 with crotonic acid 25 in the presence of PPA or P₂O5+H₃PO₄or SiO₂at 100~110℃ afforded respectively 4-methybenzodiazepinone 26 as 1:1 cycloadduct.

동종 조혈모세포이식 후 발생한 크립토콕쿠스 척추염 1예
고윤호,임동준,이성수,조유경,이동건,최정현,김유진,민창기,김동욱,박정미,김춘추,신완식 대한감염학회 2001 감염 Vol.33 No.4
Skeletal cryptococcosis is an uncommon infection. Cryptococcus is a common cause of meningitis and infects 7∼10% of patients with AIDS. As well as AIDS, the infection may be seen in association with leukemia, lymphoma, Hodgkin's disease, sarcoidosis, tuberculosis and diabetes, also in patients on steroid medication. But there is no case report of skeletal cryptococcosis following allogeneic hematopoietic stem cell transplantation. A 40-year-old woman was admitted to the hospital because of low back pain. She had chronic myelogenous leukemia for 2 years and underwent allogeneic hematopoietic stem cell transplantation 8 months ago. She have been treated with steroid and cyclosporine orally because of chronic graft versus host disease. On examination she was afebrile and had posterior lower lumbar tenderness. But, she had no reduced strength of low extremities. Open biopsy was underwent. Histology demonstrated budding, round-to-oval, refractile yeast-like organisms within debris. The results of a lumbar puncture were unremarkable and cerebrospinal fluid culture failed to grow bacteria and yeast. The patient was treated with amphotericin B (1 gram) and AmBisome□ (2.8 gram) over 6 weeks. Three months after cessation of therapy, the patient was doing well.(Korean J Infect Dis 33:298∼301, 2001)
