Azithromycin으로 치료한 임신 중 쓰쓰가무시병 1예
김광석,최진욱,서호종,김기훈,박성호,서광섭,고성만,김순혜,김호정 대한감염학회 2001 감염 Vol.33 No.5
We report a case of tsutsugamushi disease in a 26 year-old pregnant woman who was treated with azithromycin. Her gestation period was 27 weeks and she admitted with fever, rash, and eschar on the right shoulder. Currently recommended medications for the treatment of scrub typhus are doxycycline or chloramphenicol. But, these drugs are class D drugs according to the U.S. Food and Drug Administration (FDA) Fetal Risk Summary, so they couldn't be used to treat pregnant women. Recently, a few case reports suggested that azithromycin, a relatively new macrolide antibiotic, was effective and safe for the treatment of scrub typhus in pregnant women. And, there is no evidence that azithromycin causes harmful effects to the developing fetus or to children. On the basis of current in vivo test that confirms the effectiveness of azithromycin, it may be the drug of choice for the treatment of scrub typhus in pregnant women and children.

유치의 근관치료에서 치수절제술은 실활된 유치를 치열궁내에 유지하기 위해 치관과 근관부분의 괴사된 치수조직을 완전하게 제가하는 것을 말한다. 이 술식은 감염된 치수의 세균을 감소시키는 것을 목적으로 하며, 다양하고 불규칙한 유치 근관의 형태가 주된 장애 요소로 작용한다. 더욱이 비협조적인 어린이의 경우에는 오랜 시간동안 정교한 시술을 하기가 곤란하다. 최근 들어 근관치료시에 회전식 기구를 이용하여 근관형성을 하는 장비들이 많이 개발되었으며 저속전기 모터에 회전식 NiTi file을 이용한 술식이 많이 사용되고 있다. 본 증례에서는 회전식 NiTi file과 전기모터를 이용하여 유구치의 근관치료를 시도하였다. 치수강을 개방하고 치관부 치수를 제거한 후 잠정적 작업장을 측정하였으며 적절한 NiTi file을 선택하여 잠정적 작업장까지 crown-down 방법으로 점차적으로 형성하였다. 수용 file로 근단부 도달 및 성형을 하고 전체적인 마무리를 하여 Vitapex로 충전하여 양호한 결과를 얻었기에 보고하는 바이다. The pulpectomy or root canal treatment on primary teeth is to be done when there is evidence of chronic in flammation or necrosis in the radicular pulp. Due to the tortuous and ribbon-shaped anatomy of the primary teeth, the instrumentation of endodontic hand files and barbed broaches is not an easy procedure. Recently, many automatic Ni-Ti rotary instruments have been developed and has made endodontic treatment easier and faster. This report describes two cases of root canal treatment on primary molars using Ni-Ti rotary files. The cervical constricture was eliminated by the crown-down method, as smaller file proceeded unhindered into the apical third of the canal. In addition, the crown-down technique enhanced the efficacy of the endodontic irrigant. The use of rotary instrumentation for primary teeth seemed to be a more effective way to debride the uneven walls of primary teeth.

정부와의 협력이 장애인 복지시설(NPO)의 자율성과 관료화에 미친 영향 : 장애인 생활시설을 중심으로
서화자,김광혁 한국사회복지정책학회 2004 사회복지정책 Vol.18 No.-
본 연구는 비영리민간부문과 정부간 협력 방식을 통해 제공되는 사회복지서비스 형태인 비영리인간(장애인복지시설)조직의 자율성과 관료화에 미친 영향과 그 관련 변수를 밝히고자 하였다. 본 연구를 위해 전국의 장애인생활시설을 대상으로 설문조사를 실시하였으며, 선형회귀분석을 통해 연구문제를 검증하였다. 분석결과는 다음과 같다. 첫째, 재정요인은 장애인 생활시설의 자율성과 관료화와 유의미하게 관련되어 있는 것으로 나타났다. 즉, 정부지원의 비율이 작을수록 자율성의 정도가 큰 것으로 이것은 장애인 생활시설이 정부지원의 의존율을 줄이고 예산 수입을 다양화에 융통성 있는 기관운영과 서비스제공의 노력을 해야 한다는 점을 시사하고 있다. 둘째, 제도요인 역시 정부와의 협력으로 인한 문서작성과 평가가 장애인 생활시설의 자율성과 관료화와 유의미하게 관련되어 있음을 알 수 있었다. 구체적으로 정부가 제출하기를 원하는 문서의 양이 과다해 고유 업무에 지장을 초래하며 이것은 자율성을 낮추는 원인이 되고 있다. 셋째, 민간조직요인은 생활시설의 규모를 측정한 장애인 수가 자율성과 관료화에 유의미한 관계를 갖는 것으로 나타났다. 넷째, 개인 요인은 공무원의 전공이 자율성과 유의미하게 관련된 것으로 나타났다. 또한 장애인 생활시설자의 근무경력과 전공이 관료화와 유의미한 관련성을 보였다.

Objective : This study was performed to fmd clinical implications ofdistinctive pattems in bipolar patients with predominance of depressive episodes or manic episodes and to find possibilities to predict predominant episodes in bipolar disorder. Methods : The recmitment period was between 2002 and 2004, among inpatients who had received psychiatric treatment for bipolar disorder. The data about the number and the polarity of the past episodes were collected through medical records, and Sub-jects were divided into depressive or manic episode predominant groups. The two groups were compared regarding Sociodemo-graphic and clinical variables. Results : 74 patients met the inclusion criteria during the study period. 21 subjects were classified as depressive episode Pre-dominant group (depressive episode group), and 53 subjects as manic episode predominant group (manic episode group). There were no differences in sociodemographic data, the number of total episodes and hypomanic episodes, and onset age. However, 90.5% (n=19) subjects of depressive episode group showed depressive episode as first episode, and 88.7% (n=47) of manicepisode group experienced manic episode as first episode (χ²=42.13, df=1, P<0.00l). Psychotic symptomswere significantly more prominent in the manic episode group (χ²=6.85, df=1, P=0.009), and the number ofsubjects who had suicide attempt experience was higher in the depressive episode group (χ²=7.39, df=1, P=0.007). In the comparison of highest GAF scores during the past year, significant difference was found between the two group (p=0.046), as the mean scores of depressive epi-sode group was 68.337±7.47 and manic episode groupwas 71.51±5.42. Conclusion : The results ofthis study show that there are differences in clinical features according to predominant episodes in bipolar disorder. The type of onset episode appears to be related to predominant episode in this study, and it would be a valid Pa-rameter with therapeutic implication in bipolar patients.

Up to now all carton packs used for milk container in our country have been imported abroad. With rapid increase of interest on environment and waste recycling, Environmental Societies and Civil Consumer's Organization restart the Use of Glass Bottle for Milk Movement. From preliminary survey result that glass bottle had many advantages in most test items, we chose the glass bottle as substitute for carton pack, and proposed some regulations such as usable range and detailed regulation, etc. Because at this time it is impossible to rebuild whole pack manufacturing process to substitute carton pack to glass bottle, it may be more favorable to use glass bottle for milk packing under some restricted condition such as easy recollection and reusable circumstances. In addition some governmental regulations to promote glass bottle milk productions and sale and to return all used glass bottles are absolutely required in group catering system. If above is impossible, it will be next choice to set up regulations of milk packing as well as to use glass bottle at some position, and adopt a consumer deposit system in order to increase glass bottle usage, which will help environmental protection and economy.
