For investigation of the species diversity of the Genus Crepidotus in Korea and constructing a key to Korean Crepidotus species, a total of 65 specimens, collected from 18 locations from 1982 to 2002, were observed for morphological characters of carpophores and other features. All the specimens have been preserved in the herbarium of the National Institute of Agricultural Sciences and Technology, R.D.A., Suwon, Korea. The specimens were identified according to the classification systems given by Hesler and Smith(1965), Nordstein(1990), Orton(1960), Pilat(1948), Senn-Irlet(1991, 1992, 1993) and Singer(1951, 1973, 1986). In this study, a total of 10 Crepidotus species were confirmed. Among them, Korean common names were designated to six unrecorded species as follows: C. uber, "끈적귀버섯"; C. hygrophanus, "곤약귀버섯"; C. latifolius, "꼬마무리귀버섯"; C. obscurus, "먼지귀버섯"; C. subverrucisporus, "분홍주름귀버섯"; and C. circinatus, "노란고리귀버섯". A key to 10 Crepidotus species has been constructed.

This paper shows the results about field operating digital hearing aids which protect the ears of the battle field soldiers from explosive sound and minimize the difficulty of mutual communication during the battle. The essence of the hearing aid is in its signal compression technology in which soft sound is amplified while rapidly increased explosive sound is attenuated. This nonlinear compression technology can be applied for the protection of the ears of the battle field soldiers. As a core part of the hearing aid, when a new DSP IC chip is launched, the modified firmware and fitting software is developed for adaption. Ezairo 5910 which was recently launched by DSP factory in Canada was used for the development of the firmware of the hearing aid.

본 연구는 기업의 기술 유출 및 특허 침해라는 정보 보안 문제 발생 시, 브랜드 기업의 시장 지위에 따라 가해 및 피해 기업에 대한 소비자 반응이 달라질 수 있다는 점에서 착안하였다. 같은 예로 대한민국 국가대표 축구팀이 약팀과의 경기에서 졌을 때, 일부는 경기력을 비난하지만, 일부는 선수 부상, 날씨, 시차 적응 등 상황이 불리했음에도 잘 싸웠다고 평가하는 경우가 있다. 이처럼 어떤 부정적 결과 대해 사람들은 각자 다른 평가를 한다는 맥락에서 기술 유출과 특허 침해와 같은 정보 보안 문제가 발생한 기업에 대해 소비자 인식과 태도는 다르게 나타날 수 있다. 이와 같이 소비자 관점에서 기대와 실제가 불일치한 지각과정을 설명하는 심리적 메카니즘에는 동화-대조 효과가 있다. 본 연구는 기술 유출 및 특허 침해에서 일어나는 소비자 동화-대조 효과를 심리학의 귀인 이론을 통해 설명하고, 이 때 사람들의 귀인 방향이 브랜드 명성이 높을 때와 낮을 때, 기술 유출 경로가 내부자일 때와 내부자가 아닐 때에 나타나는 소비자 반응을 확인하고자 한다. 또한, 이로써 나타나는 소비자 반응을 귀인 이론의 방향성과 메커니즘을 통해 설명하려 한다. 동화-대조 효과에서 나타나는 귀인의 방향성과 소비자 반응 관계를 분석한다면, 추후 기업의 R&D와 기술 개발 전략, 지적 재산권 침해 이후 사태에 대한 대응과 수습에 가이드를 제공할 수 있을 것이라 기대한다.

This study examined the effects of auricular acupressure on female college students with functional constipation to propose auricular acupressure as an effective and evidence-based nursing intervention. This is an experimental study designed with randomization and single-blind in a Sham-control approach. The subjects included 44 female college students with functional constipation whose symptoms met the Rome IV criteria. In this study, five different acupressure sites were applied to each group; the experimental group (n=23) received auricular acupressure on rectum, large intestine, lung, san jiao, and shenmen, whereas the Sham control group (n=21) received acupressure on ankle, helix, tooth, jaw, and external ear. The intervention was implemented once a week for a total of six weeks. After six weeks, the severity of constipation, stool form, and quality of life regarding constipation in the experimental group significantly improved compared to that of the Sham control group (p<.001). Consequently, the study showed that auricular acupressure can be used as an effective nursing intervention to alleviate constipation in female college students.

As the particulate matter (PM) is fatal for human being, the government authorities try to lessen PM with a variety of policy instruments. To increase the efficiency of the policy, we need to understand people's perception and risk avoidance on PM. Thus, the research explored what attribution styles, involvement, and perceived health status have an influence on preventive intention. First, we found three attribution styles on PM occurrence through factor analysis: daily life(DL), domestic industry & environment(DI&E), and Chinese industry & environment(CI&E). We also found that involvement(${\beta}=.465$, p<.001), CI&E(${\beta}=.222$, p<.001), DL(${\beta}=.173$, p<.01), and DI&E(${\beta}=.143$, p<.05) have an influence on preventive intention in order. Finally we discussed suggestions for future study.

This study examined the relationship between psychopathology(depression, anxiety, aggression), maladaptive cognitions(negative cognitive errors, attributional biases), and age of children with ADHD. 40 ADHD children and their mother completed questionnaires assessing depression, anxiety, aggression level and maladaptive cognitions of children. The results showed that maladaptive cognitions of children with ADHD was not significantly associated with their depression, anxiety, aggression level. Age was negatively related to internal stable attributions for negative events that was characteristic in depression, and had significantly effect on internal stable attributions for negative events. As age of ADHD children increased, their internal attribution for negative events reduced. It seems that their depression and anxiety level is associated with current stress event rather than maladaptive cognitions. Suggestions and limitations of this study, and the directions for future study were discussed.

The purpose of this study was to investigate the educational needs targeted at city dwellers with hope of migration to mountain areas. 80 city dwellers participating in the education program operated by Korea Forestry Promotion Institute were selected. Results showed that city dwellers had higher preference for the education including medium scale(20-40 persons)and the type of camp with field experience. Real experiences and knowledge and understanding of migration to rural area are the most important element of the qualifications of the program teachers. In the contents of education, city dwellers wanted the teaching programs about 'how to have forest land', 'how to produce the forest products', 'field experience' and 'forest tourism' and so on. In other words, city dwellers who wanted to move to mountain areas were interested in basic things for living. In addition, it will need to investigate people who have real experiences migrating to mountain areas and then it is necessary to discuss educational needs and supporting system helping people can settle in mountain areas.

This study was carried out to examine the germanium contents of Angelica keiskei Koidz. and A. acutiloba Kitagawa and to intend to increase its contents while those leaf explants were culturing on MS medium supplemented with organic and inorganic germanium. Ge content of Agelica keiskei Koidz. was 2.1 times higher than that of A. acutiloba Kitagawa. Digestion was done quickly at high temperature, but Ge content was decreased. Callus formation of A. acutiloba Kitagawa was better than that of A. keiskei Koidz. Callus formation of both plants was good in order of pH 5.7, pH 5.4, and pH 6.0. But shoots from callus were formed frequently in A. keiskei Koidz., especially at pH 5.7. Callus formation of both plants was good up to 5 ppm of inorganic ($germanium(GeO_2),$ retarded at 10 ppm, and rarely formed at 100 ppm, but was good up to 10ppm of organic germanium retarded at 50 ppm and formed some-what even at 100 ppm.

This research investigates the role of causal inferences about the endorser's motivation - specifically, dispositional versus situational attributions - and their impact on persuasion of noncelebrity testimonial advertisements. Based on the correspondent inference theory and the relevant literature, it is posited that consumers will generate predictable patterns of attributional responses to testimonial messages, which in turn will influence ad and brand evaluations. An experiment with 335 consumer panelists, after a pilot experiment with the college student sample, has been conducted. Results suggest the greater impact of dispositional attributions than situational attributions on persuasion of noncelebrity testimonial messages and general evocations of situational attributions regardless of the levels of endorser credibility and dispositional attributions. On the basis of the findings from this study, theoretical and practical implications are discussed, as are directions for future research.
