Nineteen pepper (Capsicum annuum L.) cultivars were screened for the resistance to two common species of root-knot nematodes, Meloidogyne incognita and M. arenaria. The tested pepper cultivars showed different degrees of resistance to M. incognita but all were resistant to M. arenaria. The cultivars cv. Gonggongchil, Green No. 500 Pimento, Dahonggeon, Manitta, Shinbaram, Perfecto, and Hanmaeum were resistant to the both species of root-knot nematodes. Therefore, seven selected resistant pepper cultivars are recommended as resistant rotation crops in greenhouses where root-knot nematodes are problematic.

Korea Aerospace Research Institute(KARI) is developing COMS (Communication, Ocean and Meteorological Satellite) which is scheduled to take off in June, 2009. COMS is the first geosynchronous satellite developed in Korea which is able to perform three missions 24 hours a day. The oceanic payload was transferred from France to Korea in November, 2008 and made it possible to integrate all three payload together. After the integration COMS is planned to be transferred to Guiana Space Center (on French territory) to be launched. In this paper the trend of domestic and international development of the multi-purpose geosynchronous satellite considering the COMS is the first operational geosynchronous multipurpose satellite in the world.

Objectives : This study is to explain the effects of Yoga therapy for relieving dysmenorrhea on the aspect of Oriental Medicine and to identify the therapeutic Yoga asanas applicable to clinic medicine. Methods : We searched papers using Pubmed, CNKI and 7 Korean medical databases. We used "Yoga" and "Dysmenorrhea" as keyword. Limitations were as follows ; the last 20 years of publications and search range only including RCTs. Papers without inclusion criteria were excluded. We classified all the searched RCTs studies into Yoga exercise prescriptions. Results : A total of 47 studies were found. And 38 were excluded during extract screening. Finally 3 RCTs were selected and analyzed out of 9 papers. Blood sampling and survey questionnaires were used in the outcome measure. They reported that Yoga exercise could be used for dysmenorrhea patients, which has a curative effect. Conclusions : Yoga therapy can be explained as Meridian muscle theory in the concept of Oriental Medicine. Also, it may be a favorable choice for dysmenorrhea patients. Further studies to describe the effects of Yoga therapy will be needed more.

Purpose: This study was to explore the perception about menstruation and discomforts of using disposable menstrual pads in menstruating women. Method: A survey was conducted of 132 menstrual women recruited by convenience sampling. Data were collected by a face-to-face interview and a study questionnaire, and analyzed by frequency and $X^2$-test. Result: More than half of the subjects expressed a negative perception about menstruation, while 25% expressed a mixed perception and 24.2% expressed a positive perception. Women who perceived their menstruation negatively had more menstrual pain than the others (p<.001). The most frequently experienced discomforts of using disposable pads were an unpleasant smell (18.9%), leakage (18.9%), and discomfort (16.6%). Adverse effects of using disposable pads were reported as an itching sense (23.1%). skin rash (20.2%), and skin irritation (10.6%). Alternate materials were reported with tampons, alternate washable pads, and maternity pads. Conclusion: The results indicate that disposable menstrual pads cause several discomforts and common adverse effects such as skin problems. To decrease these discomforts and relieve adverse effects, planned nursing education including women's personal hygiene methods and information about an alternate pad may be helpful.

Purpose: This study aimed to investigate the factors of occurrence of amenorrhea and the severity of climacteric symptoms in breast cancer patients who underwent chemotherapy. Method: Women diagnosed with breast cancer without metastasis or recurrence, had surgery followed by chemotherapy, and had menses at the time of surgery were recruited from S hospital located in Seoul. A total of 99 women aged 31 thru 55 years participated and filled out a structured questionnaire including the Functional Assessment Cancer Therapy-Breast plus Endocrine Symptom when they visited the clinic for follow-up. Result: In 88 women amenorrhea occurred within an average of 2 months since beginning chemotherapy, and menstruation was resumed in only 11 women. About 98% of women aged over 40 experienced a cessation in menses thus age was an apparent factor of amenorrhea (Exp(B)=.76, p<.05). Presence of chronic disease (${\beta}=.25$, p<.05) and body weight change (${\beta}=.30$, p<.01) were significant factors influencing the severity of climacteric symptoms. Conclusion: Nurses need to have clinical evidences of menstrual changes due to breast cancer treatment. Information about premature menopause and climacteric symptoms should be provided according to women's health conditions so that they cope better during their survival.

Age and growth of Dictyosoma burgeri, sampled in the costal waters off Sanyang, Tongyeong, Ky$\breve{o}$ngnam during December 1992∼November 1993, were studied by otolith reading. Examination of outer margins of the otolith showed that the opaque zone as annulus was formed once a year with being mainly configured in November. Spawning period was estimated from January to March, with a peak in Feburary. Growth of the fish was expressed by the von Bertalanffy's equation as $L_t=23.5977(1-e^{-0.2542(t+2.1302)})$, $W_t=64.5892(1-e^{-0.2542(t+2.1302)})^{2.3002}$, where $L_t$ is total length in ㎝, $W_t$ is total weight in g and t is age.

A study on seasonal changes in age structure and fecundity of Gryllotalpa africana Palisot de Beauvois was conducted in Suwon from 1991 through 194. It seemed that most of newly hatched nymphs emerge to adults in September and October, so have a life cycle a year, and some overwinter as nymphs and emerge to adults from August, so have a life cycle tow years. The mean number of eggs per cell was $36.00\pm$2.84 for egg cells laid in the laboratory, and $47.68\pm$4.35 for egg cells collected in the field. Mean and range of the numbers of egg cells produced per female were $1.17\pm$0.19 and 0~3.

Purpose: The purpose of this study was to find out the correlation among Shift Rotation, dysmenorrhea and digestion function. Methods: We conducted a questionnaire survey of 161 nurses about their menstruation and digestion function from several hospitals from Oct to Nov in 2009. Using chi-square test and pearson correlation, statistical analysis was made by SPSS 12.0. We significance level p-value was determined as 0.05. Results: 1. There was no significant correlation between Shift Rotation and the severity of dysmenorrhea. 2. There was statistically mild correlation between Shift Rotation and digestion power. 3. There was statistically mild correlation between dyspepsia and the severity of menstruation. Conclusion: From above results, we could conclude that Shift Rotation, dyspepsia had mild relation to menstruation.

Purpose: This study is to evaluate the efficacy of non pharmacotherapy on dysmenorrhea. Methods: Survey was done through web site and directly searched dysmenorrhea -related articles in journals of Korean medicine Gynecology, published during 1996-2008. Results: 1.

Purpose: The purpose of this study was to examine whether there is difference in the effects of aromatherapy on dysmenorrhea by research design. Methods: Findings from the two different research designs (Nonequivalent control group pretest-posttest [NCG] design vs. two-group crossover design) were compared in regard to the effect of aromatherapy on dysmenorrhea. The subjects of the NCG design and the crossover design were a total of 58 female nursing students. The treatments (aroma essential oil inhalation and carrier oil inhalation) were given using a necklace. The data were analyzed by Fisher's exact test, t-test, Mann-Whitney test, paired t-test, and Shapiro-Wilk test using the SPSS/WIN 12.0 program. The effect size for the two research designs was calculated. Results: In both research designs, the level of dysmenorrhea and menstrual pain after the aroma treatment were not significantly different from those after the placebo treatment. The effect size of the NCG design was higher than that of the crossover design. Conclusion: Aroma inhalation may not be effective in managing dysmenorrhea and menstrual pain. In order to further clarify the efficiency of research design and the effect of aromatherapy on discomfort during menstruation, replication studies are necessary. Future studies need to examine the effects of different research design on non-interval variables.
