This study was reviewed from 1000 articles related to family planning from 1970 to 1990 and 20 articles associated with natural family planning from 1980 until the present. The purpose of natural family planning(NFP) is to identify the time ovulation of women themselves, to have intercourse with periodic abstinence, and to deliver a healthy child. The ultimate goal of NFP is to promote the family's health. The NFP method is described as periodic abstinence of intercourse to avoid pregnancy by identifying the ovulation time in the menstration cycle. Clinical symptoms and signs of reflection underlying changes in Estrogen and Progesterone are the change of basal body temperature, the change of cervical mucus and cervix, abdominal pain and breast tenderness. The types of NFP are the calender rthythm method, basal body temperature methods, cervical mucus method, symptothermal method, cyclo-thermal method and home based ovulation test kits. Recently the cyclo-thermal method involved. It is calendar rhythm method applied to B.B.T. For the cervical mucus method, when the estrogen level in the blood concentration is increased, the mucus begins to excrete, the amount of moist mucus increases while the mucus is clear, slippery, and smooth. For 3 days, this timing can be considered contraception. Fertility is at a maximum on the day mucus appears, abstinence for 3 days is a type of contraception. Sexual intercourse on a maximum day of mucus maximizes pregnancy potential. But, the contraception depends on the practice of a perfect rule. For basal body temperature methods, at ovulation time, the temperature increases $0.2^{\circ}C-0.5^{\circ}C$. Through the review of literature a high temperature above $0.2^{\circ}C$ for 3 days indicates that the previous 6 day period was ovulation and fertilization. The Symptothermal method is used to determine the prediction of ovulation through the observation of mucus excretion, high temperature, the change of cervical mucus, low abdominal pain, vaginal discharge, and breast change. Home based ovulation test kits are cervico-vaginal fluid aspiration, test a digital electric thermometer, body fluid(blood, saliva, urine) test kits, They are on the market. However, research on the contraception method is still in progress. For pregnancy it is still too early to use home based ovulation test kits because of deficit of reliability and simplicity more research on the technology is needed. It is suggested that NFP methods be included in nursing curriculum in order to educate NFP users how to effectively use NFP methods. Furthermore, this study has implications for the dissemination of NFP methods in terms of Korean policies of family planning and the support of community welfare agences.

This investigates the factors that affect HPV (human papillomavirus) vaccination among college nursing students. The subjects were 604 students from 3 nursing colleges located in city G. Data were collected from June to October 2015 and analyzed using SPSS 21.0 software. 14.7% were in the HPV vaccinated group and 85.3% were in the unvaccinated group. Statistical evaluations were done to determine whether vaccination had any associations with age, year in school, gender, pocket money, health beliefs, and knowledge of the HPV vaccination (p<.001). The average score of cancer prevention behavior of the students was 7.22, and the average score of health beliefs was 24.71. The most determining factor for vaccination was "recommendation from parents or significant others," and the most interfering factor for vaccination was "no interest." The significant factors affecting vaccination were the year in school, pocket money, knowledge of the HPV vaccination, and health beliefs. The vaccination rate of subjects who had knowledge of HPV vaccination was higher (OR=8.59, p<.001). These results can contribute to the limited knowledge about the HPV vaccination of college nursing students. Also, this research provides useful baseline data for increasing the rate of HPV vaccination.

HDR brachytherapy administers a large dose of radiation in a short time compare with LDR, and its optimization for treatment is related to several complex factors, such as physical, radiation and optimization algorithms, so there is a need for these to be verified for accurate dose delivery. In our approach, a previous study concerning the phantom for dose verification has been modified, and a new pelvic phantom fabricated for the purpose of localization, including a structure enabling the use of a CT or MRI system. In addition, a comparison study was performed to verify an orthogonal method that is commonly used for brachytherapy localization by comparing target coordinates from a CT system. Since the developed phantom was designed to simulate the clinical setups of cervix cancer, it included an air-filled bladder and a rectum structure shaped sphere and cylinder An N-shaped localizer was used to obtain precision coordinates from both CT and films. Moreover, the IDL 5.5 software program for Windows was used to perform coordinates analysis based on an orthogonal algorithm. The film results showed differences within 1.0 mm of the selected target points compare with the CT coordinates. For these results, a Plato planning system (Nucletron, Netherlands) could be independently verified using this phantom and software. Furthermore, the new phantom and software will be efficient and powerful qualify assurance (QA) tools in the field of brachytherapy QA.

Background: Usually, lumbar epidural block is performed on the $L_{3-4}$ interspace. This study was designed to evaluate the analgesic efficacy and shortening of labor duration comparing the $L_{1-2}$ and $L_{3-4}$ interspace epidural blocks in nulliparous normal vaginal deliveries and then investigates side effects following the blocks. Methods: Eighty healthy nulliparous women were divided into two groups, $L_{1-2}$ (n = 40) and $L_{3-4}$ (n = 40). Epidural blocks, lumbar epidural block were performed at the $L_{1-2}$ and $L_{3-4}$ interspace with a catheter advancing 3 cm cephalad. The initial dose of 12 ml (0.167% bupivacaine, fentanyl $50{\mu}g$ and clonidine $75{\mu}g$) was injected epidurally at 4 cm dilatation of cervix and severe pain of labor. If a visual analogue scale (VAS) score was more than 4 points, an additional dose was administered epidurally using the same volume as the above mentioned, but with the exception that the bupivacaine was diluted to 0.1 percentage. The maternal blood pressure, pulse rate, respiration rate and fetal heart rate were measured at 10 min intervals for the first 30 min, at 15 min interval for the next 30 min and at 30 min interval for the last one hour following the blocks. The duration of the first (active) and second stages of labor was counted and the neonatal Apgar score was recorded at one and five min after delivery. The degree of motor block, pruritus, nausea and vomiting were also noted. Results: The patients in group $L_{1-2}$ had lower pain scores than group $L_{3-4}$ at 5, 20, 30, 60 mins. The duration of 1st and 2nd labor stage in the $L_{3-4}$ epidural block were $272{\pm}33.5$ min, $49.2{\pm}27.4$ min respectively but those in the $L_{1-2}$ epidural block were $253.5{\pm}32.5$ min, $37.3{\pm}22.3$ min, respectively. Conclusions: We concluded the analgesic efficacy and shortening of labor duration in $L_{1-2}$ epidural block was better than those in $L_{3-4}$ epidural block. Maternal hemodynamic change, motor block. pruritus, nausea, vomiting and Apgar score showed no significant differences between the two groups.

There is increasing evidence that stromal reaction in cancer has an important diagnostic and prognostic significance. The aim of our study is to analyze the relation between the increase in mast cell number and the expression CD34 and alpha-smooth muscle actin (${\alpha}$-SMA) in the stroma of cervical intraepithelial neoplasia (CIN) and squamous cell carcinoma (SCC). We investigated a total of 29 CIN (1,2,3) and 21 SCC (microinvasive and invasive) specimens and compared the distribution of $CD34^+$ stromal cells, ${\alpha}-SMA^+$ cells, transforming growth factor-${\beta}1$ $(TGF-{\beta}1)^+$ cells, and the density of mast cells using immunohistochemistry with antibodies against CD34, ${\alpha}$-SMA, TGF-${\beta}1$, and c-Kit (CD117) respectively. Computerized image analysis was to evaluate the positive area (%) and density of the respective immunoreactive cells. In CIN $CD34^+$ cells were abundant in the stroma but no ${\alpha}-SMA^+$ cells were identified except the wall of blood vessels. $CD34^+$ cells were progressively decreased along the continuum from CIN 2 to microinvasive SCC and not observed in the stroma of invasive SCC. Whereas ${\alpha}-SMA^+$ cells were only observed in the stroma of microinvasive and invasive SCC. We found more intense TGF-${\beta}1$ expression in the increased mast cells in the stroma of invasive SCCs than that in the stroma of CIN. These results indicate that disappearance of $CD34^+$ stromal cells and appearance of ${\alpha}-SMA^+$ cells are associated with the stromal change of CIN to SCC and the transformation of $CD34^+$ stromal cells into ${\alpha}-SMA^+$ cells is mediated by TGF-${\beta}1$ secretions in the stromal mast cell of SCC.

Background: Artificial insemination (AI) can serve as a powerful tool to the sheep owners for making rapid genetic progress of their flock. The AI in sheep is mostly performed using fresh semen with two reasons i) lambing rate following trans-cervical AI with frozen semen is limited by the inability of frozen-thawed sperm to transit the cervix and ii) the need of circumventing the cervical barrier through laparoscope aided intrauterine AI. Therefore, AI with frozen-thawed semen is not as widespread in sheep as it is in other domestic species. However, to get maximum benefits through the use of AI, frozen-thawed semen is a prerequisite because instead of high fertility, the short shelf life of fresh semen coupled with a limitation on the number of insemination doses achievable per unit time restricts the widespread use of individual sires. Therefore, in order to enhance lambing rate, a total of 240 trans-cervical artificial inseminations with frozen-thawed semen were performed in Bharat Merino ewes during autumn season either once in the evening (G-I, 10 h after onset of estrus, n = 100) or twice (G-II, 14 h and 22 h after onset of estrus, n = 140) i.e. once in the morning and again in the evening. Results: The pregnancy rate (proportion of pregnant ewes confirmed by ultrasonography at day 40) and lambing rate (proportion of ewes lambed) were higher in G-II as compared to G-I (26.4 vs 20% and 19.3 vs 10%, respectively). The difference in lambing rates was statistically (P < 0.05) significant. The depth of insemination within cervico-uterine tract had no significant effect on pregnancy and lambing rates. Conclusions: The results indicate that lambing rate in sheep following TCAI with frozen-thawed semen was significantly influenced by time of inseminations. Two inseminations after 14 and 22 h of onset of estrus enhanced the lambing rates of Bharat Merino sheep as compare to single insemination after 10 h of onset of estrus. The TCAI technique with frozen-thawed ram semen is promising and may serve as a valuable tool for genetic improvement of sheep breeds. Research efforts are going on worldwide to overcome the poor fertility following TCAI with frozen-thawed semen.

Background: Cancer is a major cause of mortality in developing countries and correct and valid information about the epidemiology of this disease is the first step in the planning of health care in each region. The aim of this study was to determine the relative frequency, mean age and sex ratio of the most 10 common non-skin cancers in the world and Iran, among patients referred to an oncology clinic. Materials and Methods: This descriptive study was conducted in Mashhad, north east of Iran. The data obtained from the records of patients referred to the private oncology center between the years of 1985-2012". According to the latest report of GLOBOCAN study commonest malignancies included were lung, breast, colorectal, prostate, stomach, liver, cervix, esophageal, bladder cancers and Non-Hodgkin lymphoma. Results: A total of 4,606 cases were analyzed. The mean age was $55.5{\pm}13.8years$ (male: $59.5{\pm}13.9$, female: $52.6{\pm}12.9$). Overall, breast cancer (1,264 cases, relative frequency of 27.4%) was the most prevalent cancer; however the mean ages of diagnosis were not significantly different between 5-year time period divisions (p=0.290). The most common cancer in men was esophageal cancer (26.3%).The lowest mean age was related to women diagnosed with breast cancer ($48.5{\pm}11.8$) and men with non-Hodgkins lymphoma ($48.4{\pm}17.8$). There were statistically significant differences between the mean age of men and women with gastric (p=0.003) and esophageal cancers (p<0.001). Male to female sex ratios in our study for bladder, lung and stomach cancers were 6.57, 2.60 and 2.50 respectively. Conclusions: The results showed that breast cancer tends to be found in younger female patients and bladder cancer appears more often in men. Screening in target population in addition to early diagnosis may reduce death and disability.

Background: To evaluate the clinical significance of atypical squamous cells of undetermined significance (ASCUS) in PAP test in post-menopausal women and compare with reproductive age women. Materials and Methods: A total of 367 patients who referred to our gynecologic oncology clinic were included to the study between September 2012 and August 2013. Data for 164 post-menopausal (group 1) and 203 pre-menopausal (group 2) women with ASCUS cytology were evaluated retrospectively. Immediate colposcopy and endocervical curettage was performed for both groups and conization for all women with a result suggestive of CIN2-3. Histopathological results and demographic features of patients were compared between the two groups. Results: Mean age of the patients was $54.6{\pm}6.5$ years in group 1 and $38{\pm}6.6$ years in group 2. Some 14 (8.5%) of post-menopausal women and 36 (17.7%) of pre-menopausal women were current smokers (p=011). Totals of 38 (23.2%) post-menopausal and 64 (31.5%) pre-menopausal women were assessed for HPV-DNA. High risk HPV was detected in 7 (4.3%) and 21 (10.3%), respectively (p=0.029). Final histopathological results recorded were normal cervix, low grade cervical intra-epithelial neoplasia (CIN 1), and high grade cervical intra-epithelial neoplasia (CIN2-3). In group 1 results were 84.8%, 12.2% and 1.8%, respectively, and in group 2 were 71.9%, 23.2% and 4.9%. There were no cases of micro invasive or invasive cervical carcinoma in either group. Two cases were detected as endometrial carcinoma in the menopausal group (1.2%). Conclusions: In current study we found that preinvasive lesions were statistically significantly higher in pre-menopausal women than post-menopausal women with ASCUS. Cervicitis was more common in menopausal women. Therefore, we think that in case of ASCUS in a post-menopausal woman there is no need for radical management.

Purpose: To measure the dose for dose optimization at the reference point (A, B) and the critical organ with multi Purpose brachytherapy phantom (MPBP). For this wort the MPBP was custom made, and designed to reconstruct the treatment applicator using multi function applicator (MFA) in the same way as the treatment of patient. Materials and Methods: Dose measurements were made at the reference points (A, B) and the bladder with thermoluminescence dosimeter (TLD) for four patients with tandem and ovoid of uterine cervix cancer using the phantom. In Phantom, Total 20 times of the measurements were made with 5 times a patient. Results: The results of TLD measurements in MPBP phantom showed the relative error ranging from -3.2% to 3.8% at A point, and -1.4% to 4% at B point and 1.3% to 7.15% at the bladder of reference point. Conclusion: The reproducibility of dose measurement under the same condition as the treatment could be achieved using the custom-made MFA in phantom and the dose at the reference point (A, B) and bladder could be analyzed accurately. The measured dose acquired in MPBP can apply for the dose optimization.
