  • A fungal disease of the cultivated mushroom, Ganoderma lucidum, caused by Xylogone sphaerospora was epidemic throughout all cultivation areas in Korea which caused a lot of yield losses in the mushroom production. For controlling the disease, the screening of effective fungicides against the pathogenic fungus were conducted. Thirty seven commercially available fungicides were tested for their inhibitory activities on potato dextrose agar media supplemented with these fungicides at various concentrations. Twenty one fungicides significantly inhibited mycelial growth of the pathogen, Xylogone sphaerospora, but 16 fungicides had no inhibitory effect. Among these 21 fungicides, 17 fungicides also inhibited mycelial growth of Ganoderma lucidum as well, but imazalil, procymidone, triforine, and vinclozolin had no inhibitory effects. However, vinclozolin showed no inhibitory effect on mycelial growth of the mushroom even at the concentration of 50 $\mu\textrm{g}$/ml vinclozolin solution for 2 hours, and then the pathogen was inoculated. After two month-cultivation of the mushroom, over 90% of logs treated with vinclozolin without pathogen inoculation produced fruiting bodies. However, fruiting bodies were not produced form the logs inoculated with the pathogen, but not treated with vinclozolin. Fifty seven percent of logs. which were pre-treated with vinclozolin and then inoculated with the pathogen produced fruiting bodies. Based on the results, vinclozolin is effective for the control of yellow disease of the Ganoderma lucidum caused by Xylogone sphaerospora.

  • The purpose of this study was to investigate the intake and preference of Kimchi in middle school students. A questionnaire was used as the instrument of investigation. The subjects were 375 male and 278 female students in Masan and Changwon City. The main results of this study are as follows. Fifty-nine point seven percent of the subjects liked Kimchi, whereas 3.7% of them disliked it, and the main reason liking Kimchi was 'hot taste' of Kimchi. Korean cabbage Kimchi and cubed radish Kimchi were highly preferred. And the preferred dishes made with Kimchi were stir-fried rice with Kimchi, Kimchi stew, pan-fried Kimch, seaweed rice with Kimch, Kimch pancake, Mandu with Kimchi, pork stew with Kimch. More than 90% of the subjects had eaten 6 kinds of Kimchi : Korean cabbage Kimchi, cubed radish Kimchi, radish leaves Kimchi, radish root & leaves Kimchi, watery radish Kimchi, white Kimchi. The frequency of Kimchi intake was 55.1% of the subjects ate Kimchi in every meal time, and 21.9% ate 2 times in a day. They preferred 'well fermented' and 'freshly prepared' Kimchi, and it was significantly difference between gender, male students more liked 'freshly prepared', whereas female students more liked 'well fermented' Kimchi(p<0.01).

  • Objectives: To describe the time perspective of return to work and the factors that facilitate and hinder return to work in a group of survivors of acute coronary syndrome (ACS). Methods: Retrospective semi-structured telephone survey 2 to 3 years after hospitalization with 84 employed Dutch ACS-patients from one academic medical hospital. Results: Fifty-eight percent of patients returned to work within 3 months, whereas at least 88% returned to work once within 2 years. Two years after hospitalization, 12% of ACS patients had not returned to work at all, and 24% were working, but not at pre-ACS levels. For all ACS-patients, the most mentioned categories of facilitating factors to return to work were having no complaints and not having signs or symptoms of heart disease. Physical incapacity, co-morbidity, and mental incapacity were the top 3 categories of hindering factors against returning to work. Conclusion: Within 2 years, 36% of the patients had not returned to work at their pre-ACS levels. Disease factors, functional capacity, environmental factors, and personal factors were listed as affecting subjects' work ability level.

  • Effects of cultivars, cooking, and processing on hemagglutinin activity were evaluated by observing macroscopic hemagglutination using serial twofold dilution of trypsinized human blood type-O or rabbit blood. Hemagglutinin activity was expressed as maximal geometric dilution fold. Agglutination of rabbit blood was more sensitive compared to human blood. Hemagglutinin activities of glyphosate-tolerant soybean, HS2906, and imported conventional soybeans were not statistically different, although significant differences were observed among conventional soybean cultivars cultivated in Korea (286 to 1535 HU/mg protein). Time required to reach fifty percent inhibition of hemagglutinin activity ($IT_{50}$) value decreased with increasing cooking temperature and pressure. Most effective conventional cooking method to inhibit hemagglutinin activity was pressure-cooking ($IT_{50}$: 1.36 min). Calculated activation energy based on reaction rate constant was 4.88 kcal. No hemagglutinin activities were detected in processed soybean products such as tofu, soybean paste, and soysauce.

  • Premature ejaculation is the most common sexual dysfunction seen in the male, and it is found in 30 to 50% adult male population. It is defined as the inability to control the ejaculatory process for a sufficient length of time during intravaginal containment to satisfy his partner in at least fifty percent of his coital connections The majority of men with premature ejaculation have underlying psychologic origin of performance-anxiety type, but it is not always psychogenic and may also be a presenting symptom in certain organic disorders. In oriental medicine, the point of treatment of premature ejaculation is recovery of the good ejaculatory control, and the treatment can be approached in three ways as psychological therapy involving behavioral therapy, herb drugs, and acupuncture. This study has aims to investigate and summarize the current trend of treatment for premature ejaculation so as to suggest the effective and available way to treat the disease.

  • This survey was conducted to investigate the dietary behavior and health status of Buddhist nuns. In this study, 100 Buddhist nuns in Seoul were selected. The dietary survey was focused on the diet in winter. The age distribution was as follows; 24% of the subjects were in their 20s, 45% in their 30s, 23% in their 40s, and 8% in their 50's and over, respectively. The percentage of the subjects living in temples close to the downtown area was 77% and the rest resided in areas remote to the downtown area. Over fifty percent of the subjects were satisfied with their diet at temple. And 59% of the subjects were eating a snack more than once a day. The snacks included fruits (60%), raditional tea (20%), coffee (9%), bread and cookies (4%), md rice cakes (3%), etc. Among food groups, the intake of green-vegetables and fruits were the highest and intake of milk and bean products were low which may cause calcium and protein deficiency. Most of the subjects believed that their health conditions were average or above average. About 50% of subjects didn't exercise at all. The frequencies of gastro-intestinal diseases and anemia were extremely high. About 50% of subjects took some form of medicine. To improve their health and nutritional status, it is required that they practice a good dietary behavior, maintain a balanced diet, and exercise regularly.

  • Larval development and adult oviposition of the Oriental tobacco budworm, Heliothis assulta were examined with tobacco leaves sprayed with aqueous or ethanolic extracts from ten selected wild plant species. High larval mortality was observed with extracts from Rhamnus davurice. Persicaria hydroPiPer, Forsythia koreana, Trifolium repens, Styrax japonica, Ginkgo bi/oba, and vilis amurensis. Most of larval mortality occurred during first and second instar, apparently due to antifeeding effects of plant extracts. These extracts also prolonged developmental period of survived larvae and increased the number of larval molts. Oviposition was not affected as much as the larval mortality, but Rhamnus davurice and Styrax jaPonica extracts reduced the number of eggs laid by more than fifty percent.

  • Purpose: The purposes of this pilot study were to describe the perceived effectiveness of music therapy for pain control and to identify music preference for postoperative pain and anxiety control in Korean women who had a gynecological surgery. Sample: A convenience sample of 52 women was recruited from a gynecological unit at P University hospital and they were interviewed to assess their perception of music therapy and music preference using a structured study questionnaire. Results: Fifty-six percent of women reported that music therapy would be effective and 96% perceived it would be effective if combined with analgesics. The best music chosen for relieving postoperative pain and anxiety were Korean old pop and ballad song/music followed by Korean religious music, American pop songs, piano music, Korean classic songs, and Orchestra music. Conclusion: There was a cultural difference in music preference for the relief of post-operative pain in this sample. Therefore, effects of music for postoperative pain control need to be determined after considering musical preferences of postoperative women in Korea.
