월경전증후군은 여성만이 경험할 수 있는 생리 전 불편감을 치료가 필요할 정도로 심각하게 느끼는 병을 말한다. 여성의 65%가 가벼운 우울감과 같은 생리 전 불편 증상을 호소하고, 20~40%는 월경 때마다 반복되는 치료가 필요한 정도의 다양한 증상으로 월경전증후군을 앓고 있다. 또한, 이들 중 2~9%는 사회적, 직업적으로 더욱 심각한 증상 때문에 치료를 받게 되는데 이를 월경 전 불쾌장애라고 부른다.

서로의 사랑을 확인하고 행복감을 느껴야 하는 성교 시에 오히려 통증을 느낀다면 참 난처한 일이다. 성교통은 성교 전후나 혹은 성교 시에 성기뿐만 아니라 하복부에서 불쾌한 통증을 느끼는 경우인데 심한 경우엔 성교에 대한 두려움과 공포증으로 인해 성교 기피증으로까지 진행된다. 2/3의 여성에게 한 번 쯤은 경험 할수 있는 것으로써 병원에서 상담하는 가장 많은 성문제 중 하나이다.

살랑살랑 불어오는 바람마저 아름다운 이 봄이 불쾌한 이들이 있다. 바로 알레르기 질환을 앓고 있는 환자들이다. 가장 흔한 알레르기 질환에는 꽃가루병, 즉 알레르기 비염이 있으며, 이보다 흔하지는 않지만 증상이 심해 알레르기 비염보다 주목받는 기관지천식도 있다. 대표적인 만성질환 중 하나인 기관지천식에 대해서 알아본다.

중소기업에 다니는 40대 중반의 남성은 얼마 전부터 종종 가슴이 화끈거리는 불쾌한 통증과 함께, 목과 가슴 사이에 복숭아씨가 걸려있는 듯한 답답함을 느꼈다. 혹시나 심장에 이상이 있는 것이 아닌지 검사를 해보았지만, 결과는 정상이었다. 이리저리 알아보다 위액이 역류하는 경우에도 비슷한 증상이 있을 수 있다는 정보를 얻고 소화기내과를 찾았고, 내시경 검사 결과 역류성 식도염 진단을 받았다.

Recently, weather information has been increasingly used in various area. This study presents the necessity of hourly weather information for electricity demand forecasting through correlation analysis and multivariate regression model. Hourly weather data were collected by Meteorological Administration. Using electricity demand data, we considered TBATS exponential smoothing model with a sliding window method in order to forecast electricity demand. In this paper, we have shown that the incorporation of weather infromation into electrocity demand models can significantly enhance a forecasting capability.

This article on environmental noise qualify is concerned with the relationships between the annoyance and perception and sound quality metrics according to exposition time for traffic noise. For invested the characteristics of noise quality, we conducted to the subjective experiments of the annoyance response using the absolute 100 scaling method for the traffic noise sources. The traffic noise sources are composed to varieties exposition time from 15sec to 1200sec. As the results, the first there are decreased the perception loud level for the increase of exposition time with logarithm scale, but increased the annoyance. Second, evaluation index of annoyance is correlated to the loudness(sones), tonality and logarithm scale time with R2=0.83. Also, the composition ratio of traffic noise according to exposition time has the change of range as the logarithm scale ($30{\sim}50%$), tonality($27{\sim}37%$) and loudness($34{\sim}20%$).

Aromas of sulfur-containing volatiles from two vegetable varieties of Cruciferae Brassica oleracea and the suppression of undesirable sulfurous aromas of cruciferous vegetables by sulfhydryl oxidase of caraway seeds were examined. Aroma components were separated by gas chromatography equipped with a dual flame photometric detector The volatile sulfides produced from cabbage and broccoli varied. in the relative quantities and rates of production. according to the amount of caraway seeds added and incubation time. The amount of methanethiol and dimethyl disulfide in the cabbage and broccoli with caraway seeds was far less than those in the cabbage and broccoli. Removal of methanethiol and dimethyl disulfide was proportional to the amount of caraway seeds added, and was remarkable with 2.5% aqueous slurries of caraway seeds added.

Objectives : We investigated the prevalence and functional impairment of premenstrual dysphoric disorder (PMDD) and premenstrual syndrome(PMS) in young women. Methods : A total of 1063 female college students were recruited from two urban areas(Seoul and Suwon) of Korea. Questionnaires for sociodemographic data and risk factors of PMDD, attitude about menstruation, and the Premenstrual Symptoms Screening Tool(PSST) were applied. Results : The prevalence of severe moderate to severe PMS and PMDD were 16.9% and 11.7%, respectively. There were differences in the alcohol and coffee consumption, severity of menstrual cramp, and family history of PMS among the moderate to severe PMS, PMDD, and no/mild PMS groups. Although some participants did not fulfill diagnostic criteria for PMDD, they showed significant functional impairment. Participants with negative attitude about menstruation reported premenstrual symptoms more frequently than those with positive or ambivalent attitude about menstruation. Conclusion : These results suggest that PMS and PMDD were prevalent and associated with functional impairment in young females. Some participants reported significant functional impairments although they did not meet the full DSM-IV diagnostic criteria for PMDD. Negative attitude about menstruation was associated with more premenstrual symptoms experiences.

This study was carried out to decrease intrinsic objectionable odor, bitter and fishy taste and change the biobeneficial components (gastrodin and p-hydroxybenzyl alcohol) of Gastrodia elate Blume. First of all, Gastrodia elata Blume. was dipped in the rice-washed water and rice-bran solution fermented with Lactobacillus brevis and Lactobacillus plantarum. The objectionable odor, bitter and fishy taste were decreased considerably with the treatments. Gastrodia elata Blume. was also dipped in organic acids (10 different varieties). The result showed that the most effective treatment to reduce objectionable odor, bitter and fishy taste of Gastrodia elata Blume. was treated with 1.0% lactic acid. Eleven different kinds of volatile components such as acetaldehyde, formic acid ethyl ester, acetic acid ethyl ester, 4-methylphenol and 3-hydroxy-2-butanone were separated from Gastrodia elata Blume when treated with or without 1.0% lactic acid. 4-Methylphenol, which is an objectionable odor in Gastrodia elata Blume, decreased with the treatment of lactic acid. While the contents of gastrodin and p-hydroxybenzyl alcohol in Gastrodia elata Blume. increased by 20% when dipped in 1.0% lactic acid solution for 24 hours and steamed at $98^{\circ}C$ for 4 hours.

The study uses department of the sensitivity and fuzzy reasoning, one of artificial intelligence algorithms, so that develop LED lighting system based on fuzzy reasoning for systematical control of the LED color temperature. In the area of sensitivity engineering, by considering the relation between color and emotion expressed as an adjective word, the corresponding sensitivity word can be determined, By taking into consideration the relation between the brain wave measured from the human brain and the color temperature, the preferred lesson subject can be determined. From the decision of the sensitivity word and the lesson subject, we adjust the color temperature of RGB (Red, Green, Blue) LED. In addition, by using the information of the latitude and the longitude from GPS(Global Positioning System), we can calculate the on-line moving altitude of sun. By using the sensor information of both temperature and humidity, we can calculate the discomfort index. By considering the altitude of sun as well as the value of the discomfort index, the illumination of W(white) LED and the color temperature of RGB LED can be determined. The (LED) sensitivity lighting control system is bulit up by considering the sensitivity word, the lesson subject, the altitude of sun, and the discomfort index The developed sensitivity lighting control system leads to more suitable atmosphere and also the enhancement of the efficiency of lesson subjects as well as business affairs.
