Purpose: The purpose of this study was to identify an attitude toward menstruation, perimenstrual symptoms, and coping used by female college students. Methods: A convenience sample of 151 students was obtained from two nursing colleges in Mokpo and Gwangju. Data were collected through questionnaires from June 15 to June 28, 2005. Three instruments were used in this study, the menstrual symptoms, menstrual attitude, and menstrual coping. Data was analyzed by descriptive statistics, t-test, ANOVA, and Pearson correlation using SPSS 10.0 program. Results: The results showed that most 3rd and 4th year students complained about discomfort during their perimenstrual period, had a negative attitude toward menstruation due to the discomfort, but coped well during the period even with a lot of discomfort. With this results, there is a need for a nursing mediator to provide relief for discomfort during perimenstrual period so college female students have a positive attitude toward menstruation. There is a need for further research to determine the relationship between other variables and discomfort during the perimenstrual period. It is also needed to investigate if there are differences in these variables studied according to ages and occupations in women. Conclusion: From these findings, problem solving strategies for menstrual symptoms, positive attitudes, and coping should be a comprehensive approach to a nursing intervention to help women.

Purpose: The study was to survey personal hygiene practice related to genito-urinary tract and menstrual hygiene management in female adolescents in order to obtain basic information for health education. Methods: With a descriptive survey design, 389 adolescents were recruited via convenience sampling in Korea. Survey instrument was the feminine and menstrual hygiene practice and perception of vaginal douching. Data were collected from a self-administered structured questionnaire. Results: Mean age of adolescents was 16.09 and menarche was at 13.21. While washing hands after urination/defecation was highly performed, wipe front to back and wash with soap and water were reported as being not well done. Twenty-eight percent reported douching habit. More positive beliefs about douching were reported by adolescents who practiced douching. Menstrual hygiene management was very appropriate with changing sanitary pads regularly with hand washing; but less performed for limiting bathing activity during menstrual periods and washing hands after activity of genito-urinary area. Conclusion: Some adolescents practiced inadequate hygiene practices especially for body cleansing during menstrual period and vaginal douching. It is important to develop and implement school health education programs on feminine and personal hygiene for adolescents to help them perform adequate health behaviors.

Purpose: The purpose of this study was to compare the premenstrual syndrome (PMS) and the relationships among PMS, perfection, and anxiety in nursing college students and general college students. Methods: The questionnaire survey was carried out with a convenience sample of 215 college students. The MDQ (Menstrual Distress Questionnaire), APS-R (Almost Perfect Scale-Revised), STAI (State and Trait Anxiety Inventory) were used. The data were collected from June to October, 2011. Data analysis included frequency, $x^2$-test, t-test, and Pearson correlation. Results: There were significant differences in PMS and perfection but there not in anxiety between nursing college students and general college students. There were significant correlations among PMS, perfection and anxiety in nursing college students, and there were significant correlations among PMS and anxiety in general college students but not significant correlations among PMS and perfection. Conclusion: The findings suggest that to provide effective interventions for PMS in college students, it is necessary to design nursing interventions that consider perfection and anxiety.

한국산 관박쥐(Rhinolophusfewmequinum Jroma의 웅성생식 pattern을 알아보기 위하여 정소의 형태변화와 세정관 정상피의 1년주기를 조사하여 다음과 같은 결론을 얻었다. 정자형성은 5월에 시작되어 10월말에 완료되었다. 7월초부터 10월중순까지는 정자변태과정이며, 정자형성과정의 활성도가 가장 높은 달은 8월 중순경이었다. 또한 교미가 끝난 11월경부터 세정관내에는 미성숙한 정자세포가 Sertoli cell의 식작용과정의 일환으로 포식되어졌고, 91년 12월부터 92년 1월, 2월, 3월, 그리고 동면각성기인 4월의 실험군에서도 역시 점진적으로 식작용 과정을 관찰할 수 있었다. 교미가 끝난 후의 세정관 내에는 새로운 정자를 만들기 위한 준비단계로서 미성숙된 정자들이 Sertoli cell의 식작용에 의해 정화(cleaning)되므로 이 기간을 정화기간(cleaning time)이라 볼 수 있다. 따라서 정소내 세정관의 1년 주기를 볼 때 정화기간은 동면 개시기인 11월부터 익년 4월까지 약 6개월에 걸쳐 이루어 진다. 이상의 결과로 볼때, 정자형성은 동면각성 직후부터 시작하여 10월경에 완료되며 교미개시기에는 정지되고, 동면기 동안 정자형성이 일어나지 않는 점으로 보아 한국산 관박쥐는 'Pipistnfluspottem'에 속한다고 할 수 있다.

Purpose: This study was designed to examine the effects of abdominal meridian(Kyongrak) massage on menstrual cramps and dysmenorrhea. Method: Eighty-five women (of 110 screened) enrolled in this study and were employed full-time with more than 6.0 points(in $0\~10.0$ VAS scale) in menstrual cramps or more than 20 points on the dysmenorrhea scale(range $13\~52$). The forty-two participants in the experimental group received abdominal meridian massage for 5 minutes per day during 6 days from the fifth day before menstruation to the first day of menstruation and the forty-three participants in the control group didn't receive any treatment. Data were collected from June 1st to August 30th, 2003 and analyzed using descriptive statistics, $x^2-test$, and t-test. Result: Menstrual cramps and dysmenorrhea of the experimental group were significantly lower after abdominal meridian massage than those of the control group (p<.001). Conclusion: Abdominal meridian(Kyongrak) massage was very effective for relief of menstrual cramps and dysmenorrhea. Therefore, we suggest that abdominal Kyongrak massage can be a useful nursing intervention for women with menstrual cramps or dysmenorrhea.

자궁내막이 생체내 insulin-like growth factor binding protein-1(IGFBP-1)의 혈중치를 유지하는데 얼마나 관여하는지를 평가해 보았다. Immunoreactive IGFBP-1의 혈중치의 측정을 위하여, 월경과다를 주소로 내원한 19명의 환자를 대상으로, gynecologic resectoscopy로 자궁내막 박리를 시행하였다. 자궁내막 박리를 시행한 환자의 혈중 IGFBP-1의 평균치는, 시행전과 비교할 때 감소된 소견을 보였으며, 월경주기와는 상관관계가 없었다. 이러한 소견으로 보아, 자궁내막이 혈중 IGFBP-1의 생성원의 하나로 사료되었다.

Purpose: Safety concerns regarding the use of disposable sanitary pads have emerged as a social issue in Korea, and some have advocated alternatives to alleviate these concerns. However, menstrual cups are rarely viewed as an option because of the sociocultural climate. Therefore, the purpose of this study was to explore the experiences of Korean women that use menstrual cups. Methods: Hermeneutic phenomenology as suggested by Van Manen was utilized for the study. Fourteen women, who had been using menstrual cups, were recruited and asked to participated in face-to-face interviews. Interview data were transcribed and coded by lifeworld existentials. Results: Four fundamental themes were emerged from the data: adaption to menstrual cups, body's various responses towards the menstrual cups, the menstrual cups being unwelcomed in Korean society, and our various perspectives towards menstrual cups. Conclusion: We could observe not only the positive experiences in terms of using menstrual cups but also the various difficulties and challenges of using those menstrual cups in Korean society. We hope that the findings could be used as the evidence for developing health education contents and policies to promote women's health.

Purpose: The reproductive health of women in early adulthood can affect pregnancy, childbirth, and menopause in later life. Menstrual symptoms not only affect daily life, but are also a reflection of a woman's reproductive health. This study was conducted to explore the factors affecting menstrual symptoms among university students. Methods: The general characteristics, life style, menstrual characteristics, stress, and menstrual symptom of 177 female students were assessed through an online survey at one university. An independent sample t-test, one-way variance analysis, correlation analysis, and multiple regression analysis were performed using the SPSS 22.0 program. Results: The menstrual symptom score was 91.68±32.11 points, and the score of 'mood change' was the highest. Stress (��=.38, p<.001), amount of menstruation (��=.20, p=.001), menarche age (��=-.18, p=.003), health problems (��=.16, p=.010), and age (��=.15, p=.016) were found to have a significant effect on menstrual symptom, and the explanatory power of the regression model was 40%. Conclusion: This study investigated the degree and influencing factors of menstrual symptom using the Korean Menstrual Symptom Scale (KMSS) developed for Korean university students. Among the factors influencing menstrual symptom, stress appeared to play a significant role. Stress management, observation of menstrual characteristics, and general health care are necessary to maintain a woman's reproductive health.

Objectives: The objective of this in vivo study is to observe the analgesic effects or improvements of Gyejibokryeong-hwan aqueous extracts (GJBRHe) on the Primary dysmenorrhea (PD) in rats as compared to those of Indomethacin (IND). Methods: The rats were administered with estradiol benzoate for 10 days and oxytocin 1 hour after the last 10th administration of estradiol benzoate to make the primary dysmenorrhea rat model. Gyejibokryeong-hwan aqueous extracts 500, 250 and 125 mg/kg were orally administrated, for 10 days once a day. Then the changes on the body weights and gains during experimental periods, uterine weights and gross inspections, abdominal writhing response for analgesic activities, uterus lipid peroxidation (malondialdehyde (MDA) levels), antioxidant defense system - glutathione (GSH) contents, activities of superoxide dismutase (SOD) and catalase (CAT), Nuclear factor-κB (NF-κB) and Cyclooxygenase (COX)-2 mRNA expressions, were monitored with uterus histopathology and immunohistochemistry for tumor necrosis factor (TNF)-α and inducible nitric oxide synthase (iNOS). The results of Gyejibokryeong-hwan aqueous extracts were compared to those of Indomethacin adminstered rats. Results: As results of estradiol benzoate and oxytocin treatment, noticeable decreases of body weights and gains, uterus GSH contents, SOD and CAT activities, increases of abdominal writhing responses, uterus lipid peroxidation (MDA level), uterus weights, NF-κB and COX-2 mRNA expressions were observed with increases of TNF-α and iNOS immunolabeled cells, inflammatory cell infiltrations, congestion and enlargement of the uterus at gross and histopathological inspections. These means classic inflammatory and oxidative stress mediated primary dysmenorrhea are relatively well induced. However, these signs were favorably and dose-dependently inhibited by administration of three different dosages of Gyejibokryeong-hwan aqueous extracts, but lesser than those of Indomethacin. Conclusions: The results obtained in this study suggest that Gyejibokryeong-hwan aqueous extracts has favorable analgesic and refinement activities dose-dependently on the estradiol benzoate and oxytocin treatment-induced primary dysmenorrhea signs.

Objective : Premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) is known to reduce the quality of sleep and is associated with various psychiatric disorders. The aim of this study was to investigate the relationship of PMS with depression, sleep qulity and sleep pattern in Korean female adolescents. Methods : Out of 867 high school female students, 400 female subjects were included in this study. All participants completed self-report questionnaires that included demographic variables, shortened premenstrual assessment form (SPAF), patient health questionnaire-9 (PHQ-9), Pittsburgh sleep quality index (PSQI), Epworth sleepiness scale (ESS), insomnia severity index (ISI) and Korean translation of composite scale (CS). A total of 394 individuals who completed the questionnaires were analyzed. Results : As score of SPAF, 143 subjects was defined PMDD group. They had more prevalence of eveningness, more depressive symptom, poorer sleep quality, and more excessive sleepiness than non-PMDD groups. Although the PMDD groups showed more menstrual dysmenorrhea, no difference was found in bleeding duration and cycle. PMS symptom had correlations with depression, poorer sleep quality and excessive sleepiness during the daytime. There was no difference in sleep duration between two groups, but PMS might have a relationship with eveningness of chronotype. Conclusions : Among Korean female high school students, the PMS might have an association with depression and poor sleep quality, and it might lead to daytime impairment due to excessive sleepiness. An appropriate evaluation of PMS could be helpful in determining the mental health condition of adolescents.
