Women with the premenstrual dysphoric disorder (PMDD) report increased cravings for certain foods and altered taste preferences ding the premenstrual period. The objective of the present study was to investigate the association of PMDD with luteal phase food cravings, appetite, and taste preferences in 1,078 nurses. Among the 626 nurses who gave valid responses, the prevalence of PMDD and premenstrual syndrome (PMS) was 4.6% (N = 29) and 78.3% (N = 490), respectively. A highly significant increase was observed in the preference for sweet tasting foods during the luteal phase, compared to the follicular phase. Desire for sweet foods during the premenstrual period was significantly different among the three groups, being highest in the PMDD group, lower in the PMS group, and lowest in women with no symptoms. Both the PMDD and PMS groups showed significant increases in preferences for pungent tasting foods during the luteal phase. A repeated measures of analysis of variance on the taste preference data revealed that the desire for sweet tasting foods was significantly greater than for others such as salty, sour, and pungent tastes. A greater proportion of the subjects in the PMDD and PMS groups reported an increase in their total food intake during the luteal phase, compared to those women without premenstrual symptoms. Compared to the PMS group or the women with no symptoms, the PMDD group reported increased intakes of high carbohydrate foods during the luteal phase. The most commonly reported food cravings were for sauteed spicy rice cakes (ddukbokki), or for cold buckwheat noodles mixed in chili pepper sauce. These results indicate that the luteal phase food cravings, appetite and taste preferences change in accordance with the severity of the premenstrual symptoms.

This study was performed to investigate the correlation between Premenstrual syndrome (PMS) and nutritional intake, blood composition of female students. One hundred and one female students were selected as the experimental subjects at Gyeongsang National University. To assess the PMS symptoms of the subjects, a questionnaire (PAP) score based on the methods of Halbreich, Endicor and Nee was prepared with 34 different items. Dietary survey was conducted by 24­hour recall method for 3 days and nutrient intakes were analyzed by the CAN-Pro. Blood composition of WBC, RBC, Hb, Hct, Ca and Mg was measured. The average height, weight and BMI of subjects were $160.7\pm4.6cm,\;54.1\pm5.7kg\;and\;21.2\pm1.9$, respectively. Average intakes of energy, calcium, iron, zinc, vit $B_2$, and folic acid per day were $1810.2\pm344.9kcal(90.5\%\;of\;RDA),\;621.1\;197.3mg(88.7\%\;of\;RDA),\;15.9\;pm4.9mg\;(99.3\%\;of\;RDA),\;8.1\pm3.4mg(80.5\%\;of\;RDA),\;1.1\pm0.6mg(88.3\%\;of\;RDA)\;and\;234.3\pm78.6{\mu}g(93.7\%\;of\;RDA)$, respectively. Score of the behavioral symptoms, psychologic symptoms, physical symptoms and other symptoms were recorded $1.79\pm0.86,\;2.11\pm1.08,\;2.31\pm1.11\;and\;1.58\pm0.86$, respectively. The relation between PMS and menstrual cramps was significant. A significant difference was observed for menstruation amount in physical symptoms (p<0.05) and other scores (p<0.05). The group who drinks alcohol over 30g per day showed higher scores at total PAP (p<0.05), psychologic symptoms (p<0.05), physical symptoms (p<0.05), and other scores (p<0.05) than those who don't drink alcohol. Calcium in the blood showed a negative correlation with total PAF score (p<0.05), behavioral symptoms (p<0.05), physical symptoms (p<0.05) and other scores (p<0.01). Magnesium in the blood showed a negative correlation with physical symptoms (p<0.05), other score (p<0.05). WBC was negatively associated with psychologic scores (p<0.05). Hb and Hct were negatively associated with other scores (p<0.05). In conclusion, calcium intake showed a level of $88.7\%$ of RDA and this study revealed that there is a correlation between PMS and blood composition in female college students. Therefore, calcium and magnesium supplements can be beneficial to relieve PMS symptoms.

This study was conducted to investigate the relationship among clinical nurses' emotional labor, health promoting behaviors and premenstrual syndrome (PMS), as well as to clarify factors that affect nurses' PMS. This was a descriptive study of 195 clinical nurses working in one university hospital and two general hospitals in the C region. Data collection was conducted from Jul 3 until Jul 21, 2017. T-test, ANOVA, Pearson's correlation coefficient and multiple regression were used for analysis. The mean score of emotional labor was $3.35{\pm}0.63$ out of 5, that of health promoting behavior was $2.08{\pm}0.40$ out of 4 and that of PMS was $2.94{\pm}1.09$ out of 6. Premenstrual syndrome was significantly positively correlated with emotional labor (r=0.292, p<0.001) and interpersonal relationships in health promotion behavior (r=0.208, p=0.004). Factors influencing PMS were interpersonal relationships (${\beta}=0.54$, p=0.001), emotional labor (${\beta}=0.40$, p=0.001) and degree of menstrual pain (${\beta}=0.14$, p<0.001), which explained 30.0% of PMS (F=9.33, p <0.001). The results of this study suggest that intervention strategies may be necessary to decrease PMS by reducing menstrual pain, emotional labor and interpersonal relationship stress.

This research was designed to investigate the effects of Estromon including FGF271 (Female Growth Factor 271) which was developed as a phytoestrogen for post- and pre-menopausal syndrome (PMS). The oral administration of two capsules of Estromon twice a day for 3 months significantly improved PMS (Post-/Premenopausal Syndrome) about 5 times more than placebo group (OR=5.04, 95% C.1. 1.40-18.14). In the group of 24 patients having taken Estromon, the concentration of alkaline phosphatase asn the bone marker decreased by -9.3${\pm}$9.5 IU/L after 3 months with a statistic significance. Since the concentration of osteocalcin as the other bone marker also decreased in more patients in Estromon group than in placebo group, the bone density might be expected to be improved in long-term treatment. Serum human growth hormone level increased in 17 out of 24 patients. Triglycerides decreased by -8.0${\pm}$40 (mg%) after 1 month and by -4.4${\pm}$36 (mg%) after 3 months in Estomon group while triglycerides increased in both cases in placebo group (p.0.01). Therefore, PMS patients might benefit from Estromon as a phytoestrogen supplement without any serious side effects.

Emission factors for ammonia and particulate matters (PMs) from livestock buildings are of increasing importance in view of the environmental protection. While the existing emission factors were determined based on the emission inventory of other countries, in situ measurement of emission factors is required to construct an accurate emission inventory for Korea. This study is to report measurements of ammonia and PMs emissions from mechanically-ventilated pig houses, which are common types of pig barns in Korea. Ventilation rates and concentrations of ammonia and PMs were measured at the ventilation outlets of a weaner unit, a growing pig unit and a fattening pig unit to calculated the emission factors. The PMs emission was characterized with different aerodynamic diameters (PM_2.5, PM₁₀, and total suspended particulates (TSP)). The measured ammonia emission factors for weaners, growing pigs and fattening pigs were 0.225, 0.869 and 1.679 kg animal^-1 yr^-1, respectively, showing linear increase with pigs' age. The PMs emission factors for three growing stages were 0.023, 0.237 and 0.241 kg animal^-1 yr^-1, respectively for TSP, 0.017, 0.072 and 0.223 kg animal^-1 yr^-1, respectively for PM₁₀, and 0.011, 0.016 and 0.151 kg animal^-1 yr^-1, respectively for PM_2.5. PMs emissions were increased with pigs' age due to increasing feed supply and animal movement. The measured emission factors were smaller than those of the existing emission inventory indicating that the existing ones overestimate the emissions from pig buildings and also suggesting that long-term in situ monitoring at various livestock buildings is required to construct the accurate emission inventory.

This study was conducted to figure out the influential factors on premenstrual syndrome(PMS) of college female students which are to be utilized as the basic data to develop and apply programs for preventing and controlling such symptom. The subjects were 330 college female students. The data were collected from April 2, 2012 to April 6, 2012. From the results, There has been significant correlation between stress and PMS(r=.36, p<.001) and the attitude to menstruation has appeared to have significant positive correlation with PMS as well(r=.34, p<.001). Multiple regression analysis has been employed to identify the influential factors on PMS and the result has shown that menstrual attitude, grade point average for stress, smoking and dysmenorrhea have been the most significant influential factors with 27% of explanatory power. The level of significance has been high in menstrual attitude(${\beta}$=.28, p<.001), grade point average for stress(${\beta}$=.27, p<.001), smoking(${\beta}$=.20, p<.001) and dysmenorrhea(${\beta}$=.15, p<.001) respectively. In conclusion, it needs to find nursing interventions for PMS related to psychosocial factors and suggest a narrative study for improving quality of life of women with PMS.
