Owing to frequent heavy rain due to abnormal weather, the occurrence of pepper anthracnose has recently increased, which affects the supply and demand of pepper. As a result, the price of red pepper powder in 2011, for example, increased three times compared to the average year. Although anthracnose of pepper plants has been controlled by fungicides until now, it is important to develop new resistant cultivars because of the reduction of the labor force in rural area and occurrence of new anthracnose strains resistant to fungicides. National Institute of Horticultural and Herbal Science developed two pepper lines, ‘Wonye 100005’ and ‘Wonye 100006’ that are resistant to pepper anthracnose. These lines were developed by continuous selection of progenies from a cross between ‘Wonye AR1’, which were developed from interspecific hybridization and ‘TF68’. The anthracnose resistance level of the two lines was higher than that of commercial cultivars and similar to check varieties showing highest level of anthracnose resistance.

Injury to peripheral nerve somtimes lead to neuropathic pain. Nitric oxide(NO) is increased in the dorsal root ganglia (DRG) of neuropathic pain models, and L-NAME, a nitric oxide synthase (NOS) inhibitor, reduces neuropathic pain. However, it is not known that underlying mechanism of NO involvement in development and maintanence of neuropathic pain. It was found that there were three NOS isoforms-nNOS, eNOS, and iNOS. It is also necessary to investigate NOS isoforms in neuropathic pain. The aim of this study is to investigate NOS isoforms and NADPH-diaphorase expressions and underlying mechanism of NO involvement in neuropathic pain. The 5^th lambar (L5) DRG were obtaind after tight ligation of L5 an L6 spinal nerves for 7 days. Toluidine blue stain, immunohistochemistry for nNOS, eNOS, and iNOS, and NADPH-diaphorase histochemistry were performed. All specimens were observed under light microscope. nNOS expression was increased significantly in the cytoplasm of the DRG of ligated side at 7 day post-ligation (7D PL). eNOS expression was also increased in the blood vessel, a few neurons or satellite cells, and cell membrane of Schwann cells in the DRG of ligated side at 7D PL. iNOS expression was increased in a few blood vessels and cytoplasm of small neurons in the DRG of ligated side at 7D PL. NADPH-diaphorase expression was increased significantly in the neurons of the DRG of ligate side at 7D PL, but NADPH-diaphorase expressions were weak or absent in the blood vessel and Schwann cell in the contralateral DRG and the DRG of ligated side at 7D PL. It is suggested that NOS isoforms may be closely related to development and mantanence of neuropathic pain in order of nNOS>eNOS>iNOS.

This study was designed to examine the effects of diphehydramine and promethazine on the toxic manifestation of neostigmine. It was found that diphenhydramine and promethazine increase acetylcholinesterase activity in liver of mice. When diphenhydramine and promethazine was treated before administration of neostigmine, it significantly extend the onset latency in the signs of toxicities which were characteristically produced by neostigmine and it also prevented lethality in all of the animals.
하이퍼텍스트 유형과 자기주도성이 학업성취에 미치는 효과

본 연구의 목적은 하이퍼텍스트 유형과 자기주도성이 학업성취에 미치는 효과를 규명하려는 것이다. 이를 위해 경기 H시 소재 H고등학교 1학년 2학급 69명을 대상으로 자기주도성 검사를 실시하여 평균점수 이상을 얻은 학생을 자기주도성이 높은 집단으로, 그 미만을 얻은 학생을 자지주도성이 낮은 집단으로 분류하여 실험처치를 하였다. 연구 결과, 하이퍼텍스트 유형은 학업성취에 영향을 미치지 않았으나 학습자의 자기주도성은 학업성취도에 영향을 미치는 것으로 나타났다. 또한 하이퍼텍스트 유형과 학습자의 자기주도성이 학업성취도에 미치는 상호작용 효과가 있는 것으로 밝혀졌다. 본 연구는 비교적 짧은 기간에 이루어져 지속적인 학습효과를 검증하는데 한계가 있기 때문에 장기간에 걸친 연구가 필요하다. 또한 자기주도성 이외의 학습자 특성을 고려한 연구와 컴퓨터일반 교과 외 다양한 학습내용으로 하는 후속 연구가 필요하다. The purpose of this study was to find effects of hypertext structure and self-direction on learning performance. To reach the goal, we got 69 H highschool students and tested self-direction we treat hypertext program to them. The results found were that hypertext style(non-structure, structure) didn’t effect on academic achievement but did effect learner’s self direction. Also, we found interactive effect of hypertext structure and self-direction on academic achievement. Following studies have limits verified learning effect, because this studies are carried out in short-term research. Further studies need the study of effect of hypertext structure and self-direction on academic achievement for a long-term research. Also, further studies should accomplish the study considering learner characteristics besides self-direction and will need succeeding studies including various learning contents besides computer general curriculum.

The quality properties of green onion as affected by drying was studied. The drying methods were hot-air drying, vacuum drying and freeze drying. The color (lightness, yellowness and ΔE) showed similar trend to drying methods. However, hot-air drying showed the greatest change in browning degree. The content of ascorbic acid was 26.48 ppm (hot-air drying), 52.29 ppm (vacuum drying) and 67.61 ppm (freeze drying). The rehydration rate of dried green onion were higher in the order of freeze drying>vacuum drying>hot-air drying. From the results, the quality properties of green onion in hot-air drying were higher decreased than those in vacuum drying and freeze drying methods, which were similarly changed.

In order to compare the quality properties with drying methods, soybean curd were studied through hot-air drying, vacuum drying and freeze drying methods. The color(lightness and ΔE) was decreased by drying, and showed similar trend to drying methods. However, hot-air drying showed the greatest change in browning and protein denaturation degree. Also, the hardness after rehydrated was the highest in hot-air drying. From the results, the quality properties of soybean curd were the most decreased by hot-air drying, and vacuum drying and freeze drying methods were similar changed.

The Effects of a Social Skills Program on Improving Sociability, and Adaptive Behaviors of Children with Developmental Disabilities. The purpose of this study was to investigate the effects of a social skills program on improving social skills, and adaptive behaviors of children with developmental disabilities. A total of nine children at the Language Therapy Center for children and adolescents in Gwangju Metropolitan City participated in this study with the consent from their parents. The research was conducted following one-group pretest-posttest design, a preexperimental design. A social skills program was implemented once a week with 90 minutes per session for 15 weeks. The effects of the program were evaluated by administering Social Maturity Scale, and Adaptive Behavior Scale before and after the program. The results showed that the scores in social maturity, and adaptive behavior scales, respectively, increased from pretest to posttest. This study concluded with a discussion on the implications of social skill programs for improving social skills, and adaptive behaviors of children with developmental disabilities in the field of social welfare. Implications and suggestion for future studies was discussed.
