As a result of extensive research efforts on the oriental medicinal herbs, some of their interesting biological activities have been elucidated. In the present study, antifatigue effects of two natural food supplements consisting of oriental herbs, Vital and Vigilor, were investigated using the ICR mice. The mice were fed with antibiotic-free normal mouse feed containing Vital or Vigilor for 14,28, or 31 days and then subjected to forced swim tests. In a test carried out in melting-ice water, Vital and Vigilor significantly increased the exhaustion times of the 28 day-fed mice by 26.9 % (p < 0.01) and 16.2% (p < 0.05), respectively. However, in the other test performed at 15±0.5℃ using 31 day-fed mice, Vigilor failed to increase the exhaustion time significantly (at p< 0.05), while Vital showed antifatigue effect by increasing the swimming time by 29.9% (p<0.01). Neither of Vital nor Vigilor exerted antifatigue effects in a swim test carried out on day 14 after the initiation of feeding. These results suggest that Vital and Vigilor exhert antifatigue effets when administered for a sufficient period of time by enhancing the health of the host animals.

하이퍼-프리젠테이션 개념은 하이퍼-미디어 개념을 확장한 것으로, 동적으로 연출되고 있는 상황에서 링크개념을 설정하여 특정시점이나 지점에서 원하는 다음 정보를 보기 위해서 비순차적으로 연출할 수 있도록 하는 연출이다. 이러한 비순차적인 연출방법인 하이퍼-프리젠테이션 개념을 도입함으로써, 자유로운 멀티미디어 연출이 가능하게 되었지만, 이러한 동기화 방법에 의해서 혼합된 여러 프레젠테이션들간에는 일관성 문제가 발생할 수 있다. 본 논문에서는 하이퍼-프리젠테이션 명시 프로그램의 일관성 검증을 위해서 Petri Net을 이용한 하이퍼-프리젠테이션 명시 방법을 제시하고, 그것을 이용한 명시 프로그램의 일관성을 검증하는 방법을 제안한다. The concept of a hyperpresentation, as an extension of a hypermedia, is the presentation in which time-varying multimedia presentations are dynamically linked together and a hyperlink's context can be changed over time at any time during a continuous presentation. While this concept provides users with a flexible and powerful tool for their descriptions of the multimedia presentation, inconsistency problems in the synchronized presentations connected by hyper links can be introduced. This paper introduces a method of describing the hyperpresentation using Petri Net and proposes a methods of detecting inconsistent hyper link loop in the hyperpresentation description.

김학성,민봉희 대구대학교 기초과학연구소 1988 基礎科學硏究 Vol.5 No.-

This study was carried out to investigate the trichothecene mycotoxin productivity of Fusarium tricinctum NRRL 3229. F. tricinctum was cultured on cereal grains at temperature from 10℃ to 15℃ for 4 weeks. Toxins were extracted with solvent and purified partially by column chromatography. The amounts of T-2 toxin, HT-2 toxin, diacetoxyscirpenol and T-2 tetraol were quantitated by gas-liquid chromatography. Corn and millet had the highest productivity of trochothecene mycotoxin. The highest levels of T-2 toxin and HT-2 toxin were produced on corn and maximal yield of T-2 tetraol was obtained in cultures on millet. However, no detectable amount of diacetoxyscirpenol was observed in this experiment. Metabolism of T-2 toxins showed high differences among cereal grains. T-2 toxin was metabolized easily into HT-2 toxin in corn, polished rice, glutinous rice, and sorghum and metabolized very slowly into T-2 tetraol toxin. However, T-2 toxin in unpolished rice was metabolized into HT-2 toxin and T-2 tetraol. Also, T-2 toxin was metabolized rapidly into HT-2 toxin and T-2 tetraol in barley, wheat, millet and red bean while T-2 toxin in unpolished rice was metabolized very slowly into HT-2 toxin and T-2 tetraol.

This study was conducted to investigate effects of cultivation area and planting time on bulb growth and enlargement of Lilium oriental hybrids in seed buld production. Planting time was divided into three periods such as May 15, 30, June 15 and Cultivation areas were alpine Daegwallyong and low land Kangnung area. The results were as follows: 1.The temperature of Daegwallyong from June to September was around 16-18℃ which was the optimum temperature for growth of Lilium oriental hybrids compared with above 20℃ of Kangnung area. 2.The bulb emergence rate in Kangnung area was 1-3 days faster than Daegwallyong. As the planting time was delayed, the bulb emergence rate was faster. 3.There was no significant difference in plant height between cultivation area and cultivars, but as the planting time was delayed, the plant height in Kangnung was much longer than Daegwallyong. 4.The chlorophyll content was high in the early planting time and that in Daegwallyong was higher than Kangnung. 5.The fresh and dry weight of leave was increased in Daegwallyong cultivation, compared with Kangnung. 6.The growth of underground parts such as numbers and length of basic roots and root system of stem roots in Daegwallyong was much better than Kangnung. 7.Virus infection rate in Daegwallyong was lower than Kangnung, but in the phytophthora blight and leaf blight vice versa. 8.The faster the planting time was, the higher the bulb weight was. And the bulb weight in Daegwallyong was 93% higher than Kangnung.

The purposes of this study were to examine the job satisfaction and role conflict of female elementary school teachers, and to analyze the relationship between those two factors. The following four research questions were raised. 1. What are the causal factors that brings about the job satisfaction of female elementary school teachers? 2. In regard to these causal factors, are there significant differences dependant upon such variables as teaching experience, the size of schools, and marital status? 3. What is the level of role conflict for married female elementary school teachers, and how significant are the differences according to the above variables? 4. What are the relationships between the job satisfaction factors and role conflicts of female elementary school teachers? For the purpose of this study, the researchers conducted questionnaire survey to the 300 female elementary school teachers in Kyong-nam Province. The study instrument is composed of 38 five-point Likert type questions. Major results of this research were as follows. First, the causal factors that bring about the job satisfaction of female elementary school teachers largely include school administration, a sense of recognition, promotions and raises, a physical environment, job duties, relationships with other teachers, meaningfulness of teaching, and working conditions. Second, the score on the job satisfaction of female elementary school teachers was above average(3.42 of 5.00). In regard to teaching experience, the respondents who have more than 20 years of experience had higer scores than the other groups of respondents. As for the size of schools, it was shown that schools with fewer than 23 classes had a relatively higher satisfaction rate than the other groups. Marital status had no significant differences. Third, the degree of the role conflict of married female elementary school teachers was low on the whole. Rather than the role conflict between home life and teaching duties as a teacher, the one as a housewife who has a job was greater. While teaching experience had no significant differences, the number of children had significant relations with female teachers role conflicts. Fourth, it was shown that the relationship between the causal factors of job satisfaction and role conflict of female elementary school teachers had no significant co-relationships.
