In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

The object of this study was to investigate caries preventive effect of chewing gum containing xylitol, funoran, calcium hydrogen phosphate and casein phosphopeptide by examining Vickers' hardness and surface roughness with confocal laser microscope. Early caries-like lesions were created using 0.1 M lactic acid-sodium hydroxide buffer(pH 4.0). 8 pieces of 3am diameter bovine enamel specimen with early caries-like lesions were mounted into the recesses of lingual surface of the acrylic mandibular removable appliance. 13 subjects were the appliance for daytime and chewed control and experimental gums 7 times in a day, for 3 days. In order to evaluate the remineralization effect of chewing gum on specimens, we measured vickers' hardness number after chewing gum, 1 day, 2 days, 3 days after and calculated surface roughness immediately after chewing gum. Vickers' hardness number of experimental chewing gum was significantly higher than control in 2 and 3 days after. Surface roughness of experimental chewing gum was significantly lower than control immediately after chewing gum. These results showed that experimental gum has more effective in remineralization of bovine tooth enamel, and it is more effective at immediately after chewing.

The weldability window in magnetic pulse welding (MPW) is proposed for the end-closure joining of HT-9 steel tubularworkpieces. Based on both theoretical and experimental investigations, the impact velocity of the flyer tube at the momentof collision had a dominant effect on the bonding characteristics of the resultant joints and the optimal impact velocity wasestimated to be in the range of 265–290 m/s in this alloy system. Under the optimal process conditions, no leak was detectedduring helium leak testing. Moreover, the integrity of the joint interface was preserved until the tube section ruptured duringinternal pressure burst testing. For HT-9 steel, the ductile δ-ferrite phase produced by the localized interfacial melting duringMPW acted as an effective obstacle to crack propagation, thereby enhancing the fracture resistance of the joint interface. Allof the results demonstrated the high integrity and durability of the HT-9 steel tube assembly fabricated by the MPW process.

백혈병환자에서 Liposomal Amphotericin B로 치료된 파종성 Fusarium 감염 1예

Fusarium spp.는 사람에서 드물게 각막염, 조갑진균증, 상처나 화상부위감염 등을 유발하는 것으로 알려져 있으나 최근에는 면역저하자에서 기회감염의 원인균으로 증가하고 있는 추세이다. 면역저하자에서 파종성 감염이 있는 경우에 예후는 치명적이나, 증례가 많지 않고 진단방법이 제한되어 있어 조기 진단과 신속한 치료가 쉽지 않다. 그러나 특징적으로 피부병변의 동반이 흔하여 면역저하자에서는 피부 병변의 면밀한 관찰과 함께 Fusarium 감염을 조기에 의심하여 피부생검이나 배양을 하는 것이 진단에 도움이 되리라 생각된다. 파종성 Fusarium 감염의 치료로는 감염 부위의 국소적 외과적 절제와 전신적 항진균제의 사용이 필요하고 현재까지는 amphotericin B가 비교적 효율적인 항진균제로 알려져 있으나 면역저하자에서 이에 반응을 하지 않는 경우가 많다. 저자들은 급성골수성백혈병 환자에서 관해유도화학요법 시행 후 호중구감소상태에서 피부병변과 폐침윤이 발견되었고 피부의 중심부 궤양을 동반한 구진성 병변에서 배양검사를 통해 파종성 Fusarium 감염을 진단하였으며 liposomal amphotericin B (AmBisome )를 사용하여 성공적으로 치료한 예를 경험하여 보고하는 바이다. Fusarium spp., basically a superficial pathogen, is a newly emerging fungal pathogen of opportunistic infections in immunocompromised patients. At present, although Fusarium spp. are relatively resistant to amphotericin B, the combination of amphotericin B and surgical debridement appear to be optimal treatment for disseminated infection. Recently we experienced a 32-year-old neutropenic patient after induction chemotherapy for acute myelocytic leukemia presented with skin lesions and infiltrations in both lungs. We diagnosed with disseminated fusariosis by skin culture and successfully treated the patient with liposomal amphotericin B. We emphasize a high index of suspicion for skin lesions especially in immunocopromised patients.

The ultimate strength of plate girder precedes by the estimation of the buckling strength the ultimate strength of the flange, the web, and the web reinforced by longitudinal and transverse stiffeners. The ultimate strength of plate girder has to be separately estimated under bending moment, shear force and both forces. Collecting and evaluating many related data and reference published during the last two decades in foreign countrys, this thesis presents a rational formula of the ultimate strength, which has produced good agreement between the analytic and the experimental values. In order to estimate the ultimate strength of steel plate girder based on the ultimate strength design method or the limit state design method, each analytic ultimate strength for bending moment panel and for shear force panel has been estimated and then compared with the experimental ones for following two cases, i.e. without stiffeners and with many stiffeners reinforced in a longitudinal and transverse direction, respectively. It is observed that the ultimate strength of plate girder can be increased by properly designing the number and the arrangement of longitudinal and transverse stiffeners in the plate girder.

In this thesis, I tried to explain the relationship between the deaf identity and the psychosocial function of Korean deaf adolescents, such as a state of mind, meeting with stress, family adaptability and student adaptation to school. In advance, therefore, comparing the result with the established deaf identities in the United States, I analyzed the states of the deaf identities into four sub-categories and I could clarify the broad meaning of doing a social work. Then I could discover the interrelation between the four sub-categories and a state of mind, meeting with stress, family adaptability and student adaptation to school. These are the results of this study. First, the deaf identity of Lorean deaf adolescents turned out to be different from American's established one. Second, the more marginal identity increase, the more a state of mind improver to an affirmative state. Third, obviously evasively negative alternation strategy appeared in meeting with stress. Fourth, with having difficulty communicating with his parents, and with low family adaptability, the atmosphere of family life and the deaf identity of deaf adolescents in deaf school turned out not to have any correlations. Fifth, it turned out that with lower school life, the higher the hearing identity got, the less the student adaptation to school decreased, but they had a correlation. 본 연구는 한국에 살고 있는 농 청소년의 농 정체성이 정신건강 수준, 스트레스 대처방식, 가정생활과 학교생활 적응과 같은 농 청소년의 심리사회적 기능과 어떤 관계를 갖고 있는지를 밝혀보고자 하였다. 이를 통해 먼저 농 정체성의 4가지 하위영역별로 농 정체성 수준을 파악하고, 그 결과를 선행연구된 미국의 농 정체성과 비교하여 살펴봄으로써 사회사업실천의 함의를 찾아보았고, 다음으로 농 정체성의 각 하위영역별 수준에 따라 정신건강 수준과 스트레스 대처방식, 가정생활의 적응과 학교생활의 적응에 어떤 상관관계가 있는지를 살펴보았다. 본 연구의 결과는 다음과 같다. 첫째, 한국 농 청소년의 농 정체성은 선행연구된 미국의 농 정체성과 다르게 나타났다. 둘째, 주변 정체성이 증가할수록 정신건강 수준이 긍정적인 수준으로 향상되었다. 셋째, 스트레스 대처방식에서는 부정적인 회피적 대처전략이 강하게 나타났다. 넷째, 부모와의 의사소통에 어려움이 있었고, 이로 인해 가정생활 적응 수준이 낮았으며 가정생활 환경이 농 학교에 재학 중인 농 청소년의 농 정체성과 거의 상관관계가 이루어지지 못하고 있음이 밝혀졌다. 다섯째, 학교생활 수준도 낮게 나타났으며 청인중심 정체성이 높아질수록 학교생활 적응은 감소하는 경향이 약하지만, 상관성이 있는 것으로 파악되었다.

This clinical study evaluated the whitening effect and safety of polymer based-pen type BlancTis Forte(NIBEC) containing 8.3% carbamide peroxide. Twenty volunteers used the BlancTis Forte whitening agent for 2 hours twice a day for 4 weeks As a control. Whitening Effect Pen (LG) containing 3% hydrogen peroxide was used by 20 volunteers using the same protocol. The change in shade (ΔE^(*) color difference) was measured using Shadepilot™ (DeguDent) before, during and after bleaching (2 weeks, 4 weeks and postbleaching 4 weeks). A clinical examination for any side effects (tooth hypersensitivity or soft tissue complications) was also performed at each check-up. The following results were obtained. 1 Both the experimental and control groups displayed a noticeable change in shade (ΔE) of over 2 No significant differences were found between the two group (p>0.05) implying that the two agents have a similar whitening effect. 2 The whitening effect was mainly due to changes in a and b values rather than in L value (brightness). The experimental group showed a significantly higher change in b value thus yellow shade than the control(p < 0.05) 3 None of the participants complained of tooth hypersensitivity or soft tissue complications confirming the safety of both whitening agents 8.3%의 carbamide peroxide를 함유한 펜형 코팅용 미백제인 BlancTis Forte (NIBEC, Seosul & JinCheon)를 실험군으로, 3% hydrogen peroxide를 함유한글 Whitening Effect Pen (LG. Seoul) 제재를 대조군으로 각각 피험자 20명에게 2시간씩 1일 2회 제조사의 지시대로 치아표면에 4주간 적용하도록 지시하고 색조개선 효능과 안전성을 평가하였다. 미백 효과는 미백 전 및 미백 2주, 4주 및 미백 종료 4주 후에 Shadopilot™을 이용하여 색 변화를 측정하였고, 매 내원시기마다 모든 환자는 치수생활력 검사와 치주 및 치태 검사를 통해 부작용 여부 (치아과민증 및 구감 내 연조직의 부작용)를 기록한 후 다음과 같은 결과를 얻었다. 1.실험군 및 대조군의 색 변화량 (ΔE)은 2이상으로 인지할 수 있는 색 변화를 보였으며, 두 제품 간에는 통계적으로 유의한 차이를 보이지 않아 (p > 0.05) 유사한 미백효능을 나타냄을 알 수 있었다. 2,미백효과는 명도의 개선보다는 주로 a. b값의 변화에 의한 것으로 특히 실험군에서 b값의 변화, 즉 황색조의 개선효과가 대조군에 비해 유의성 있게 높은 것으로 나타났다 (p <0.05). 3.치아나 치은의 과민증이나 이상증상을 호소하는 피험자는 없어 두 제품 모두 안전성을 확인할 수 있었다.
