목적 : 자궁암의 방사선치료시 호발하는 직장 부작용은 직장 방사선량과 관계가 있다는 보고들이 많다. ICRU 38에 따른 직장 선량을 측정함으로 강내 방사선치료 시에 조사되는 직장선량의 정도 관리에 기여할 수 있다고 생각하여 전산상 계산된 선량과 강내치료시 다이오드 검출기로 직접 측정된 직장 선량의 차이를 비교해 보고자 하였다. 대상 : 2001년 6월-2002년 2월까지 고선량율 Iridium-192 동위원소를 이용하여 고선량율 강내 방사선치료를 시행 받은 자궁경부암 환자 9명을 대상으로 하였다. 강내치료는 주 2회씩 A점에 총 $6\~8$회간 총 $28\~32\;Gy$ 시행되었다 9명에서 총 44회의 강내치료 중 선량 측정이 가능하였고, 모의치료 계획시의 필름 및 분할 고선량율 강내 방사선치료 시에 촬영한 필름을 기준으로 전산화 계획 시스템상 계산한 직장 기준점 선량과 강내치료를 하면서 다이오드 직장 검출기에서 측정된 선량을 각각 분석하였다. 결과 : 모의치료시 필름을 기준한 직장의 전산화 계획상의 선량과 강내치료 시마다 촬영한 필름으로 다시 전산화 계획상 계산한 직장선량값 사이에는 상당한 차이가 있었다. 강내치료시에 촬영한 사진을 기준으로 전산화 설계에서 계산된 값과 강내치료 중에 검출기로 측정한 직장 선량 사이에도 차이가 많았다. 직장 검출기 표시점의 치료계획 선량을 5개 점에서 계산해 보았을 때 ICRU 38 직장 기준점이 최대 직장 선량점과 일치하는 경우는 $22.2\%$ (2/9)에 불과하였다. 결론 : 자궁암에서 고선량율 강내 방사선치료 선량을 계획할 때 모의 치료시 촬영한 필름만 가지고 직장 선량을 최적화하는 것이 가장 적절한 방법이라고 볼 수는 없다. 본 연구를 통해 고선량율 강내치료시의 직장 선량이 치료시마다 상당히 변화가 많다는 사실을 확인하였으므로 가능하면 직장선량을 실측하거나 아니면 최소한 직장표지기를 삽입하고 측방 투시를 함으로 직장 위치를 파악하는 것이 자궁암의 고선량을 강내 방사선치료에서 정도관리 면에서 중요한 과정이라 생각한다.

계란의 난각은 닭의 자궁에서 형성되는 복잡하고 고도화된 다층 석회화 구조이다. 본 연구는 닭의 산란연령에 따른 자궁내막조직의 변화 양상과 난각 형성에 관여하는 주요 유전자들의 발현 양상을 고찰하였다. 난각 형성과 관련하여 난각 단백질과 관련한 OCX-32, OCX-36, OC-17, OC-116 유전자와 난각 이온과 관련한 CALB1, SPP1, SCNN1G, ATP2A2, CA2, CALM1 유전자를 분석대상으로 하였다. 자궁내막조직의 현미경적 관찰 결과, 연령이 증가함에 따라, 자궁 섬모상피세포의 탈락 및 세포의 위축과 섬유화 진행양상이 심화되었다. 그러나 연령 증가에 따른 혈중 이온성분의 농도차이는 없었다. 자궁내막 상피세포의 텔로미어 함량 분석 결과, 산란연령이 증가함에 따라 텔로미어 함유율이 감소됨을 확인하였다. 대부분의 난각 형성 관련 유전자의 발현량은 산란연령에 따라 유의한 변화를 나타내었다. 일부 난각 단백질 관련 유전자의 발현량은 산란연령이 증가함에 따라 증가양상을 보였으나, 이들 유전자들 간의 상호 관련성은 유의한 관계를 보이지 않았다. 난각 형성 이온 관련 유전자인 ATP2A2, SCNN1G, CA2, CALM1 유전자 간에는 상호 밀접한 관련이 있는 것으로 나타났다. 또한 난각 단백질 관련 OCX-32 및 OCX-36 유전자는 대부분의 이온 관련 유전자들과 높은 정의 상관을 보였다. 따라서 OCX-32, OCX-36, CALB-1, ATP2A2, SCNN1G, CA2 및 CALM1유전자들이 난각 형성에 상호 협력하거나 또는 독립적으로 작용한다. 결론적으로 산란연령이 증가함에 따라 자궁내막세포의 손상이 일어나지만, 그럼에도 불구하고 정상적인 난각을 형성할 수 있는 이유는 난각 단백질 및 난각 형성 이온 관련 일부 유전자들이 발현을 조절하여 난각 형성의 항상성 유지하기 때문인 것으로 사료된다.

Purpose: This study was done to evaluate postoperative patient satisfaction, vaginal bleeding, and sexual function in women after laparoscopic supracervical hysterectomy (LSH). Methods: A retrospective study was conducted using a questionnaire mailed to 131 women who underwent LSH between 2008 and 2011at the Department of Obstetrics &Gynecology, D University Hospital in Chungnam province. Indication for LSH was uterine myoma. The questionnaire contained questions on overall postoperative satisfaction, influence on quality of life of vaginal bleeding, and sexual satisfaction following surgery. Data were collected from March to July 2013 and 109 (83.2%) patients returned the questionnaire. Results: Most women reported being very satisfied (90.8%) or satisfied (7.3%), but 2 women (1.8%) were not satisfied with LSH. Four patients (3.4%) reported experiencing vaginal bleeding but with no negative influence on quality of life. Of sexually active women, 82 patients (90.1%) reported improvements in sexual function, 8 patients (8.8%) reported "no change", and one patient (1.1%) reported a deterioration Conclusion: Results of this study indicate that LSH is associated with a high degree of patient satisfaction, no negative influence on quality of life from vaginal bleeding, and improvement in sexual function to a minimum 2 years after the procedure.

The hospital, clinical department and the physician factor in explaining variations of hospital resource use in surgically admitted patients was compared. This analysis was based on 6, 361 discharges in 28 hospitals for three surgical conditions - lens procedures anal and stomal procedures, uterine and ovarian procedures using medical insurnce claim data. The results were as follows: 1. Regression analysis indicated that the hospital and clinical department characteristics, such as hospital ownership and size, were more significant predictors of the resource use indicators than the physician and patients' social characteristics. 2. Regarding to the physician factors, the hospital where the physician received the residency training and the medical shool where he/she graduated had less effect compared to the hospitals where he/she currently works. Between the residency trained hospital and medical school, the is more important than the latter. 3. When the hospital charges were divided into type of service provided i. e. room, drug, laboratory & radiologic, procedure & operation, and anesthesic charges, variance due to the hospital factor was larger than that due to the physician factor in each item. In summary, the hospital and clinical departmental factor played an important role than physician factor ; indicating to reduce the variation in hospital resource use, the policy that affects hospital behavior would be more effective than that targets individual physician behavior.

Aim: To evaluate precancerous lesions such as hyperplasia and endometrial polyps in obese postmenopausal women. Materials and Methods: Women who were referred with abnormal uterine bleeding in postmenopausal period or the presence of endometrial cells on cervical cytology in our department were investigated. Anthropometric measurements such as height, weight, body mass index, waist/hip ratio and endometrial thickness were compared between a precancerous lesion (hyperplasia and endometrial polyp) group and a pathologically normal group. Results: We detected statistically significant thickening of endometrium in patients with precancerous lesions. Moreover patients with precancerous lesions had higher body mass index than the pathologically normal group. Conclusions: We found elevated precancerous lesion rates in overweight and obese women in the postmenopausal period, of interest given that the prevalence of obesity is increasing in most parts of the world. Although screening for endometrial cancer is not recommended for the general population, in high-risk populations like obese postmenopausal women, it may be very important.

Purpose: The purpose of this study was to examine the influences of sex-relatedl knowledge, sex-related attitude and knowledge of cervical cancer on knowledge of human papilloma virus (HPV) among female high school students. Methods: A cross-sectional descriptive study was conducted with a convenience sample of 545 second-grade female high school students of three different schools. Results: Knowledge of HPV was positively correlated with sex-related knowledge (r=.36, p<.001), sex-related attitude (r=.14 p=.001) and knowledge of cervical cancer (r=.62, p<.001). Significant predictors affecting knowledge of HPV among female high school students were knowledge of cervical cancer (${\beta}$=.57) and sex-related knowledge (${\beta}$=.11), explaining 39.6% of the variance in knowledge of cervical cancer among female high school students (F=178.34, p<.001). Conclusion: Based on the outcomes of this study, in order to improve knowledge of HPV among female high school students, school based sexual education linked to HPV and cervical cancer must be included in the curriculum.

Purpose: In the study effects of San-Yin-Jiao (SP6) acupressure on anxiety and pulse during labor, and on neonatal status were examined. Method: The design was a randomized controlled clinical trial with a double-blind method. Data were collected before (pre) and after (post) treatment using structured questionnaire, anxiety scale, pulse rate, umbilical vein pH and Apgar scores. The experimental group received SP6 acupressure for the duration of each uterine contraction over a period of 30 minutes, but the control group received SP6 touch. Results: The anxiety scores between the two groups increased, but the increase was less in the SP6 acupressure group and the difference was statistically significant (p=0.019). Maternal pulse rate was not significantly different immediately after treatment (p=0.711), at 30 and at 60 minutes (p=0.140 ; p=0.108), but while the SP6 acupressure group had a stable pulse, the SP6 touch group showed an increased rate. There was no significant difference between the two groups for umbilical vein pH (p=0.124), and neonatal Apgar score at one and five minutes (p=0.387 ; p=0.979). Conclusion: These findings strengthen the belief that SP-6 acupressure can be used to relieve anxiety during labor with no side effects to either mother or baby.

Purpose: To provide accurate information on induced labor and find strategies to enhance women's childbirth satisfaction. Methods: Participants were pregnant women expected to have normal vaginal delivery. A total of 113 women with induced labor and 61 women with spontaneous labor were surveyed. Data were collected using a questionnaire and electronic medical records. Results: The following variables related to labor progress showed significant differences between the induced labor group and the spontaneous labor group: length of the first stage of labor in primigravidas, use of analgesic, incidence of uterine hyperstimulation, incidence of fetal distress, and medical treatment for the expectant mother. Delivery type and the incidence of postpartum complications showed significant difference between the two groups. Induced labor women's childbirth satisfaction was mainly affected by the process of labor whereas spontaneous labor women's childbirth satisfaction was affected by the outcome of childbirth. Conclusion: Medical staff should have accurate information on the risk of induced labor and the benefits of a natural delivery. Moreover, medical staff should provide necessary information and environment for women to participate in the decision-making process.

Background: Cervical cancer is a major preventable cancers. The, current study aimed to assess relevant knowledge and attitude of female students and hospital staff in Iran. Method: This cross-sectional study was conducted in Medical and Nursing faculties and hospitals of East-Azerbaijan Province of Iran. Participants were medical and paramedical female students and female staff in hospitals selected by stratified random sampling techniques. Tools for data collection were questionnaires for which validity and reliability had been verified (${\alpha}=0.8$). Descriptive and inferential statistics were used to analyze data with SPSS.16. Result: Response rates were 71 % (426 from 600) and 63.5% (254 from 400) for students and staff, respectively. Some 29.1% admitted that they had no information about cervical cancer, only 70 (10.3%) thinking their knowledge as high, 360 (52.9%) as intermediate, and 237 (34.9%) as low. While 93% of participants considered cervical cancer as a severe health problem, the only statistically significant relationships with knowledge were for education (p<.001) and occupation (p<.001) variables. Conclusion: Given the importance of the roles of medical students and personnel as information sources and leaders in health and preventive behavior, increasing and improving their scientific understanding seems vital. Comprehensive and appropriate education of all people and especially students and personnel of medical sciences and improving attitudes towards cervical cancer and its monitoring are to be recommended.
