Culdocentesis is a procedure that checks for abnormal Quid in the space just behind the vagina (cul-de-sac). First, a pelvic examination is done. Then, after exposing the postehor vaginal fonix with a bivalve vaginal speculum the posterior lip of the cervix is grasped with a tenaculum. The cul-de-sac is then entered through the postehor vaginal wall with an 18-20 gauge needle with a syringe inserted. As the cul-de-sac is entered, suction is applied, and the intraperitoneal contents are aspirated. In the recent past, culdocentesis was commonly used in the evaluation of a vahety of common intraperitoneal conditions, principally, the hemorrhage associated with ectopic gestations and ruptured ovarian cysts the presence and/or drainage of purulent associated with pelvic inGammatory disease, and as a screening procedure to facilitate early diagnosis of ovarian neoplasms. Usually 16-18 gauge needle with a syhnge attached was used for culdocentesis. But we have experienced a case of therapeutic culdocentesis with 16 gauge angioneedle in patient of hemoperitoneum. So, report it with a bhef review of literature.

Helicobacter pylori infection was the cause of chronic gastritis, duodenal ulcer and gastric MALT lymphoma. The eradication rates of H. pylori using antibiotics are around 80%. Lactobacilli have been demonstrated to have in vivo and in vitro inhibitory effects on H. pylori infection. We aimed to evaluate the inhibitory effect of L. lactis CBT-8 and its extract on H. pylori in human stomach. Thirty-five H. pylori-infected volunteers(30-49 yr)were randomized into two groups which were treated with L. lactis CBT-8 and its extract(Group A n=17) or milk containing L. lactis CBT-8(Group B, n=18). They underwent 13C-urea breath tests before and after treatment. The DOB30 of group A(n=14) was decreased 41.0% after treatment(26.0±4.9 before, 15.3±2.1 after treatment)(p<0.05). the DOB30 of group B(n=13) was decreased 22.3% after treatment(22.0±2.2 before, 17.1±1.7 after treatment)(p<0.05). In conclusion, L. lactis CBT-8 was effective in suppressing H. pylori infection in human stomach.

직무 스트레스 평가를 위한 측정도구 개발 및 표준화 연구 (Ⅰ) : 신뢰도와 타당도 Reliability and Validity Study

이동수,김지혜,한우상,우종민,강동우,고영건,연병길,김이영 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.5

연구목적 : 본 연구는 우리나라 실정에 적합하게 직무 스트레스(job stress)를 측정하고자 Osipow와 Spokane(1992)의 이론적 모형에 기초한 직무 스트레스 검사를 개발하고, 그 신뢰도 및 타당도를 검증할 목적으로 실시하였다. 방 법 : Osipow와 Spokane(1992)의 이론에 근거하여 한국판 직무 스트레스 검사(The Korean Version of Occupational Stress Inventory)를 제작하였다. 문항분석을 거쳐 최종적으로 직무 역할(Occupational Role Questionnaire ; ORQ), 개인적 긴장(Personal Strain Questionnaire ; PSQ), 개인적 자원〕(Personal Resource Questionnaire ; PRQ) 등 세 가지 하위 영역의 총 140문항으로 검사를 구성하였다. 한국직업사전의 직업분류에 기초하여 총 7개 직종군의 805명(남성 76.5%, 여성 23.5%)에게 검사를 시행한 뒤 직무 스트레스 척도의 신뢰도 및 타당도에 대한 연구를 실시하였다. 결 과 : 1) 직무 스트레스 검사의 신뢰도에 대한 분석에서 직무 역할(ORQ), 개인적 긴장(PSQ), 개인적 자원(PRQ) 각 하위 영역에 대해서는 .89∼.92 14개 하위 척도에 대해서는 .70∼.88의 높은 내적 일관성 신뢰도계수 α를 얻을 수 있었다. 8주 간격으로 검사-재검사를 실시하였을 때의 신뢰도 계수는 .62∼.79였으며, 2개 언어 사용자를 대상으로 한국어판 검사와 영어판 검사를 모두 실시하였을 때의 상관 계수는 .82∼.96으로 나타나서 전반적으로 높은 수준의 신뢰도를 확인하였다. 2) 타당도 분석에서 개인이 경험하는 직무 스트레스의 수준은 대처 자원과 유의한 부적 상관관계(γ=-.29)를 나타냈고, 스트레스로 인한 긴장과는 유의한 정적 상관관계(γ=.69)를 나타냈으며, 개인의 대처 자원은 스트레스로 인한 긴장과 유의한 부적 상관관계를 나타냈다(γ=-.40). 전체 직무 스트레스 검사에 대한 요인분석 결과, 전반적인 스트레스 요인과 그에 따른 반응, 스트레스에 대한 개인의 대처기술, 스트레스에 대한 개인의 심리적, 신체적, 행동적 반응 등 세 가지 요인이 추출됨으로써, 이론적 모형에 따른 구성타당도가 입증되었다. 결 론 : 본 연구에서 개발된 검사는 그 높은 신뢰도와 타당도가 입증됨으로써, 직장인의 직무 스트레스 경험을 체계적으로 이해하는 데 유용하게 활용될 수 있는 도구임이 확인되었다. 향후 직무 스트레스의 구체적 원인과 그 대처방법을 규명하고 나아가 직무 스트레스와 각종 정신적 신체적 질환의 관련성을 과학적으로 평가함으로써, 스트레스로 인해 고통받는 일반 직장인 및 환자의 치료에 기여할 수 있으리라 기대한다. Objectives : The present study explored the reliability and the validity of our newly constructed job stress scale, the Korean version of the Occupational Stress Inventory(K-OSI). Methods : Through preliminary item-analysis, we constructed 140 items of the Korean version of Occupational Stress Inventory(K-OSI). K-OSI consists of three subscales measuring three sections, 'ORQ'(Occupational Role Questionnaire), 'PSQ'(Personal Strain Questionnaire), and 'PRQ'(Personal Resource Questionnaire), respectively. The normative group consisted of 805 adult workers who represented six major job classes in Korea. Results : The internal consistency coefficients of 'ORQ', 'PSQ', and 'PRQ' ranged from .89 to .92, and of those 14 subscales ranged from .70 to .88. The test-retest reliability coefficients of 8 week duration ranged from .62 to .79, and bilingual's consistency coefficient ranged from .82 to .96. The validity of the K-OSI was investigated by factor-analysis, yielding 3 factors of overall job stress and its responses, personal stress coping, psychological, physical, and behavioral responses of job stress. Conclusion : The present results indicate that the K-OSI is a reliable and valid measure of job stress.
