Objectives: The purpose of this article is not until to investigate the changes and types of statistical methods and to point out the statistical errors after analyzing the method of articles that improve the quality of the statistical analysis of papers published in the Journal of Oriental Obstetrics and Gynecology. Methods: Papers published in the Journal of Oriental Obstetrics and Gynecology from 2009 to 2011 were reviewed for methodological and statistical validity using a modified version of Ahn's checklist. A statistician reviewed individual papers and evaluated the list items in the checklist for each paper. To avoid the potential assessment error by the statistician who lacks expertise in the field of Oriental Obstetrics and Gynecology. Results: A total of 190 papers including 64 original articles, 40 reviews article, 58 case report and 28 brief communication were reviewed. Statistics methods used in 121 papers were composed of t-test(58.7%), ANOVA test(19.8%) and ${\chi}^2$- test (14.0%) et al. Whereas only 14.9% of papers were free of statistical errors, the number of omission errors was 58 and the number of commission errors was 149 each. Conclusions: A variety of statistical errors were encountered in papers published in the Journal of Oriental Obstetrics and Gynecology. Accordingly, researchers should be more careful when it comes to describing and applying statistical methods.

Objective This study was to identify the risk factors for cytological progression in women with atypical squamous cells of undetermined significance (ASC-US) or low-grade squamous intraepithelial lesions (LSIL). Methods We analyzed data from women infected with the human papillomavirus (HPV) who participated in the Korean HPV cohort study. The cohort recruited women aged 20-60 years with abnormal cervical cytology (ASC-US or LSIL) from April 2010. All women were followed-up at every 6-month intervals with cervical cytology and HPV DNA testing. Results Of the 1,158 women included, 654 (56.5%) and 504 (43.5%) women showed ASC-US and LSIL, respectively. At the time of enrollment, 143 women tested positive for HPV 16 (85 single and 58 multiple infections). Cervical cytology performed in the HPV 16-positive women showed progression in 27%, no change in 23%, and regression in 50% of the women at the six-month follow-up. The progression rate associated with HPV 16 infection was higher than that with infection caused by other HPV types (relative risk [RR], 1.75; 95% confidence interval [CI], 1.08-2.84; P=0.028). The cytological progression rate in women with persistent HPV 16 infection was higher than that in women with incidental or cleared infections (P<0.001). Logistic regression analysis showed a significant relationship between cigarette smoking and cytological progression (RR, 4.15; 95% CI, 1.01-17.00). Conclusion The cytological progression rate in HPV 16-positive women with ASC-US or LSIL is higher than that in women infected with other HPV types. Additionally, cigarette smoking may play a role in cytological progression.

46,XY 핵형인 남성에게서 $17{\alpha}$-hydroxylase의 결핍이 있을 경우 성호르몬의 생성장애로 인해 남성가성반음양에 의한 여성 표현형을 보이게 된다. 코티졸이 결핍되면 부신피질자극호르몬의 증가 및 이로 인한 광불무신피질호르몬의 합성이 증가되어 저레닌성 고혈압, 저칼륨혈증이 발생한다. 41세 된 여자 환자가 원발성 무월경과 고혈압을 주소로 내원하였다. 46,XY 핵형을 보였으며, 호르몬 검사상, 혈중 에스트라디올, 테스토스테론, 레닌, 코티졸이 감소되어 있으며 부신피질자극호르몬 및 deoxycorticosterone이 증가되어 있어 $17{\alpha}$-hydroxylase 결핍에 의한 남성가성반음양으로 진단되었다. 이 질환의 치료로 복강경을 이용한 양측 고환적출술을 시행하였고, 부신피질호르몬과 항고혈압 재제, 에스트로젠을 투여하였다. 본 연구에서는 위 증례에 대하여 간단한 문헌고찰과 함께 보고하는 바이다.

Objectives: This survey was conducted to investigate the satisfaction level of the project of providing free herbal medicines to mothers living in Suncheon who gave birth to more than three. Methods: Using the online survey tool Survey Monkey, the mother was sent a questionnaire in a cell phone text to answer the questions on their cell phones. The mothers' contact information was based on the application form for a woman with three or more children, and a total of 27 people were surveyed and 20 responded. Results: The lowest level of satisfaction was 51 percent, the highest level of satisfaction was 100 percent, and the average was 86 percent. Conclusions: As the satisfaction level of the free herbal medicine support program is generally high, it is necessary to maintain the business continuously. And if other oriental medicine treatment is applied, more positive effect can be expected.

목 적: 보조생식술에서의 정자처리법으로서 인간 난포액을 이용한 swim-down 방법의 유용성을 확인해 보고자 하였다. 연구방법: 분당서울대학교병원 산부인과에서 불임평가 목적으로 정액검사를 시행할 때 정자무력증 (asthenozoospermia, sperm motility < 50%)을 보이는 12명의 남성을 대상으로 하였다. 이들에서 검사 후 남은 정액을 100% 인간 난포액을 이용한 swim-down법과 SpermGrad를 이용한 밀도차 분리법을 적용하여 각각 처리하고 컴퓨터 정액분석기를 이용하여 정액검사를 시행하였다. 결 과: 두 군 모두에서 운동성과 빠른 운동성 정자의 비율, VCL (curvilinear velocity), ALH (amplitude of lateral head displacement)치 및 과활동성 정자의 비율이 통계적으로 유의하게 상승하였고 LIN (mean linearity)치는 유의하게 감소하였다. 100% 인간 난포액을 이용한 swim-down법에서 정자의 운동성이 SpermGrad를 이용한 밀도차분리법에 비하여 유의하게 높게 나타났으며 ($81.2{\pm}4.7$ vs. $67.6{\pm}2.3$, p=0.02), 다른 변수들은 두 군에서 차이를 보이지 않았다. 결 론: 100% 인간 난포액을 이용한 swim-down법은 정자무력증을 보이는 경우 유용한 정자 처리법으로 사료된다.

The purpose of this study was to improve the experience of visiting obstetrics and gynecology of single women. After analyzing previous studies on Korean single women's perception of visiting obstetrics and gynecology, Contextual Interviews and Cultural Probes were conducted on single women in their 20s who visited obstetrics and gynecology. Based on this, personas were constructed to solidify the direction of problem solving by identifying the behavioral patterns and characteristics of single women. In this study, factors that hinder unmarried women's visits to obstetrics and gynecology and improvement measures were derived based on the information obtained using service design tools such as User Journey Mapping and Stakeholders' Map. Afterwards, a preference survey was conducted to increase the persuasiveness of the proposed method. The follow-up research task is to produce and propose the derived solution as a prototype that can be used in the actual field, and then proceed with user evaluation.

Background: To determine the cut-off values of the preoperative risk of malignancy index (RMI) used in differentiating benign or malignant adnexal masses and to determine their significance in differential diagnosis by comparison of different systems. Materials and Methods: 191 operated women were assessed retrospectively. RMI of 1, 2, 3 and 4; cut-off values for an effective benign or malignant differentiation together with sensitivity, specificity, negative and positive predictive values were calculated. Results: Cut-off value for RMI 1 was found to be 250; there was significant (p<0.001) compatibility at this level with sensitivity of 60%, positive predictive value (PPV) of 75%, specificity of 93%, negative predictive value (NPV) of 88% and an overall compliance rate of 85%. When RMI 2 and 3 was obtained with a cut-off value of 200, there was significant (p<0.001) compatibility at this level for RMI 2 with sensitivity of 67%, PPV of 67%, specificity of 89%, NPV of 89%, histopathologic correlation of 84% while RMI 3 had significant (p<0.001) compatibility at the same level with sensitivity of 63%, PPV of 69%, specificity of 91%, NPV of 88% and a histopathologic correlation of 84%. Significant (p<0.001) compatibility for RMI 4 with a sensitivity of 67%, PPV of 73%, specificity of 92%, NPV of 89% and a histopathologic correlation of 86% was obtained at the cut-off level 400. Conclusions: RMI have a significant predictability in differentiating benign and malignant adnexal masses, thus can effectively be used in clinical practice.
