Purpose: This paper presented a descriptive study which aimed to identify the relationship among menstrual attitude, premenstrual distress and premenstrual coping in Korean college women and to propose fundamental data for the development of guidelines for effective management of premenstrual distress. Methods: The data were collected from 111 college women and analyzed using descriptive statistics, t-tests, ANOVA and Pearson's correlation coefficients. Results: The mean score of premenstrual coping was $3.25{\pm}0.60$ out of 5 points. The 'Awareness and Acceptance of Premenstrual Change' score was highest and the 'Avoiding Harm' score was lowest. Menstrual attitude was significantly related to premenstrual distress (r=.37 p<.001) and the awareness and acceptance style of premenstrual coping (r=-.21. p=.021). And premenstrual distress was significantly related to the self-care coping style of premenstrual coping (r=.30, p=.001), the adjusting energy coping style of premenstrual coping (r=.45, p<.001) and the avoiding harm coping style of premenstrual coping (r=.48, p<.001). Conclusion: Results of this study support that positive attitude about menstruation is necessary for the effective management of premenstrual distress. Also, premenstrual coping programs that consider the level of premenstrual distress will be needed for college women.

The purpose of this study was to investigate the relationship among the variables and the influence of premenstrual syndrome and stress response on the learning flow of nursing students. Method : The participants were 162 nursing students in K city, who were surveyed between June 1 and June 10, 2018, using self-report questionnaire. Result: There were positive correlation between premenstrual syndrome of participants and stress response(r=.389, p<.001). There were negative correlation between premenstrual syndrome and learning flow(r=-1.93, p<.014), between stress response and learning flow(r=-.216 p<.001). The variables for learning flow where stress response(${\beta}=-.314$, p<.001) and Psychological change of menstruation(${\beta}=-.358$, p<.001), with a coefficient of determination($R^2$) of 30.3%. The result of this study will be useful in preparing basic date for improvement of the learning flow of the nursing students and it will be necessary to develop educational programs and strategies related with the premenstrual syndrome and stress response disposition.

Purpose: The menstrual cycle of normal premenopausal patients was divide into menstrual flow phase, proliferative phase, ovulatory phase, secretory phase. The aim of this study was to ovarian and endometrial $^{18}F$-FDG uptake during the menstrual cycle in normal premenopausal patients. Materials and Methods: We identified 200 incidental $^{18}F$-FDG uptake in the ovary. The patient fasted at least 6 hours before receiving an intravenous injection of 370-592 MBq (10-16mCi) of $^{18}F$-FDG. Scanning from the base of the skull though the mid thigh was performed using the Discovery Ste PET/CT system (GE Healthcare, Milwaukee, WI, USA). Ovarian and endometrial $^{18}F$-FDG uptake (expressed as standardized uptake value) was measured on PET/CT image. Results: Two peaks of increased endometrial $^{18}F$-FDG uptake were identified during the menstrual cycle. The $SUV_{avg}$ and $SUV_{max}$ was $2.89{\pm}1.04$ and $3.17{\pm}1.59$ in menstruating patients, $2.4{\pm}0.88$ and $2.98{\pm}1.14$ in proliferative phase patients, $3.59{\pm}1.76$ and $3.17{\pm}1.67$ in ovulatory phase patients, $2.58{\pm}1.39$ and $3.1{\pm}1.8$ in secretory phase patients. Conclusions: Increased ovarian and endometrial $^{18}F$-FDG uptake could be found the time of menstrual flow and ovulatory phase of menstrual cycle. Increased uptake in endometrial adjacent to a cervical tumor does not necessarily reflect endometrial tumor invasion. Since increased uptake was dependent on the menstrual cycle, it can be avoided by scheduling PET/CT just after menstruation. Non-menstrual-related endometrial uptake may be instrumental in establishing a diagnosis in a premenopaual patient.

Purpose: $^{18}F$-FDG PET/CT has been known a useful modality to diagnose high-glucose-using cells such as cancer cells by glucose metabolism of FDG. Mainly, FDG takes on cancer and inflammatory cells; However, There have been FDG uptakes on normal tissues by individual physiological characteristics, occasionally. Especially, in fertile females, unusual FDG uptake of breast changes as the menstrual cycle, and disturb diagnosis. Therefore, the study aimed to evaluate the change of breast FDG uptake in menstrual cycle on $^{18}F$-FDG PET/CT. Materials and Methods: 160 females ($34{\pm}3.5$ years old) who do not undergo a gynecologic anamnesis and have regular menstrual cycle over the previous 6 months were examined, from March 2009 to February 2010. They were divided 4 groups (each 40 patients) as flow phase, proliferative phase, ovulatory phase and secretory phase using Pregnancy Calculator 0.14. and history taking. Discovery Ste (GE Healthcare, Milwaukee, Mi, USA) was used as PET/CT. We analyzed SUVs on accumulated region on breast, and 3 nuclear medicine specialists did the Blind test. Results: SUVs on the Breast were flow phase ($1.64{\pm}0.25$), proliferative phase ($0.93{\pm}0.28$), ovulatory phase ($1.66{\pm}0.26$) and secretory phase ($1.77{\pm}0.28$). It showed high uptake value in secretory, flow phase and ovulatory phase (p<0.05). In gross analysis, the accumulation of breast was divided into 3 grades as comparing with lung and liver. The breast's uptake was equal to lung (Grade I); between lung and liver (Grade II); equal to or greater than liver (Grade III). The results showed high uptake value in secretory, flow phase and ovulatory phase (p<0.05). Conclusion: In fertile females, FDG uptake of breast changed as menstrual cycle, and it available to diagnose breast disease. Therefore, we consider reducing false-negative finding of breast disease, by doing examination on appropriate period through history taking about individual menstrual cycle.

Purpose: This study is to investigate the pattern of discomfort, coping style and relief level of female workers. Methods: The subjects were 394 women who worked at three general hospitals located in S city and agreed to the purpose of this study. Data were collected April 20~30, 2010, and one-way ANOVA and Pearson's correlation were performed using descriptive statistics using SAS 9.2. Results: showed that discomfort during menstruation was significantly different from age, marital status, pregnancy experience, and birth experience. The average degree of discomfort during menstruation was $2.46{\pm}0.68$, which was the average of 5, and the pattern was pain, water accumulation and behavior change. The degree of mitigation according to coping strategies was the most effective at $3.55{\pm}0.58$, and the relationship between coping behavior and discomfort during menstruation was correlated only with avoidant coping. p = .001). Conclusion: In order to mitigate the inconvenience of menstruation, women should seek to cope with their own coping strategies rather than passive coping methods and suggest the development of an educational program that can relieve the discomfort during menstruation.

The purpose of this study was to identify the change of energy intake, blood sugar and body composition in accordance with menstrual cycle among the women with the premenstrual dysphoric disorder (PMDD) group and women with no premenstrual symptoms (NPS) group. Energy and carbohydrate intake were significantly increased in luteal and menstrual phases than follicular phase in both groups. Protein intake was significantly increased in luteal phase than follicular phase in both of groups. Fat intake was not difference in according to the menstrual phases in both groups. Weight and body water were significantly increased in luteal and menstrual phases than follicular phase in both groups. Fat mass was significantly increased in luteal phase than follicular phase in both groups. However, the differences in energy, carbohydrate, protein and fat intake, weight, body water and fat mass between groups were not significant. Above finding of this study showed that women's energy intake and body composition have connection with change of menstrual cycle and implied that more systematic study which affects menstrual cycle is requested.

The purpose of this study was to identify the change in the girth of anthropometric variables during menstrual cycle, and to provide basal data for health promotion program development during pre-menstrual phase and menstrual phase. Participants were 10 healthy women university students without menstrual irregularity, subjective premenstrual syndrome, premenstrual dysphoric disorder, dymenorrhea, obstetrician and gynecologic disease. Chest girth(axillary and papillary), waist girth(half point between iliac crest and 12th rib, and navel), and hip girth were repeatedly measured in menstrual phase, follicular phase, luteal phase during single menstrual cycle. As a result, axillary chest girth in menstrual phase was significantly increased than that in luteal phase. Papillary chest girth and waist girth at half point between iliac crest and 12th rib in menstrual phase were significantly increased than those in follicular phase. No significance was shown in chest and waist girth between follicular and luteal phase. No significance was shown in hip girth during menstrual cycle. In conclusion, signicant difference was shown in chest and waist girth during menstrual cycle. And it is suggested that succeeding research should be carried out with reference to body weight, body fat, blood and local hormone concentration during menstrual cycle.

This study is a descriptive study to identify the patterns of use of menstrual sanitary products among community women of childbearing age. The participants were 1,571 women between the ages of 19 and 40, and data collection was conducted through online and mobile surveys from September 2020 to August 2021. As a result, 88.9% of the participants were using disposable menstrual pad, 5.6% tampons, 3.1% cloth menstrual pad, and followed by others(2.4%), including menstrual cups. The differences of type of menstrual sanitary products according to general characteristics showed significant in age(p=.006), marital status(p=.005), education level(p=.002), annual salary(p=.018), experience of pregnancy(p=.036), and menstrual regularity(p=.022). More than half of the participants(53.8%) responded that cloth menstrual pads were 'very safe' or 'safe,' but 27.9% and 20.1% of disposable menstrual pads and tampons, respectively. The difference in menstrual distress according to the type of menstrual sanitary products showed that tampon users had a higher menstrual discomfort score for the most recent menstruation(F=4.092, p=.017) and 4 days before menstruation(F=4.178, p=.016) than users of disposable menstrual pad or cloth menstrual pad. Therefore, it is necessary to continuously investigate the use of menstrual sanitary products by women of childbearing age and its relationship with reproductive health.

Objectives : Premenstrual syndrome(PMS) is known to occur in more than 80% of reproductive women. Since PMS is closely related to changes in sex hormones, biological factors are suspected to be associated with the syndrome, but there have been no consistent reports regarding biological causes. In that sense, it is postulated that the occurrence of PMS is much dependent on the biological aspects, but that the severity or characteristics of the syndrome is more dependent on the psychological factors. Studies focusing on psychological factors are based on the theory that symptoms of PMS and previous psychologically traumatic events are closely related. If the theory is valid, it can be further postulated that symptom severity of PMS is associated with dissociative symptoms, since traumatic events are known to be related to dissociative symptoms. In this study, we tried to find out the association of PMS symptom severity with previous abuse history and dissociative symptoms. Methods : Subjects for the study were 377 nurses working in Seoul, Kyung-gi, and Kyung-book. 183 subjects who submitted valid data entered the study. The presence and the symptom severity of PMS were rated using Daily Records of Severity of Problems(DRSP) and Shortened Premenstrual Assessment Form(SPAF). Dissociative symptoms were evaluated with Dissociation Experience Scale Korean version(DES-K). Previous physical/verbal abuse, sexual abuse, and parental spouse abuse experience were rated with correspondent abuse scales. Results : Subjects were divided into 3 groups as No PMS group, mild to moderate PMS group, and severe PMS group according to SPAF total score. There was a statistically significant difference in DES-K total score among 3 groups($x^2=14.966$, df=2, p=0.001). Physical/verbal abuse scale($x^2=14.397$, df=2, p=0.001), sexual abuse scale($x^2=8.376$, df=2, p=0.015), and parental spouse abuse scale($x^2=9.322$, df=2, p=0.009) also revealed a significant difference among 3 groups. Symptom severity of PMS using SPAF total score showed a positive correlation both with degree of dissociative experience and previous abuse experience. There was a statistically significant difference in both dissociative experience and previous abuse experience among 3 groups. Conclusion : These results show that there can be a possible association among PMS symptoms, dissociative symptoms, and previous psychologically traumatic experience.
