Morels (Morchella spp.) are valuable medicinal and edible mushrooms. In this study, chemical profiles of aromas and lipophilic extracts of black morel (Morchella importuna) grown in China were analyzed by gas chromatography/mass spectroscopy, along with the evaluation of antioxidant and antimicrobial activities for the lipophilic extracts. Sixty-five compounds in total were identified from the aromas, and 1-octen-3-ol was the main component for aromas of fresh (34.40%) and freeze-dried (68.61%) black morels, while the most abundant compound for the aroma of the oven-dried sample was 2(5H)-furanone (13.95%). From the lipophilic extracts, 29 compounds were identified with linoleic acid as the main compound for fresh (77.37%) and freeze-dried (56.46%) black morels and steroids (92.41%) as the main constituent for an oven-dried sample. All three lipophilic extracts showed moderate antioxidant activities against 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) with the IC50 values ranging 7.56~17.52 mg/mL and 5.75~9.73 mg/mL, respectively, and no obvious antimicrobial activity was observed for lipophilic extracts. The drying methods affect the chemical profile of black morel, and freeze-drying was favorable for retaining nutrients and morel smell. This is the first report on the aroma and lipophilic extracts of M. importuna grown in China.

디지털 환경하에서 소비자들의 제품 및 서비스 구매 형태가 변화하고 있으며 특히 문화콘텐츠에 대한 소비자의 태도와 소비 행동이 변화하고 있다. 소셜네트워크서비스(SNS)와 같이 고객간 상호작용이 확대된 경우에는 소비자의 정보적 참여가 확대되고 온라인과 오프라인에서의 문화콘텐츠 소비관련 태도에도 영향을 줄 것을 예상할 수 있다. 본 연구에서는 SNS를 사용하는 디지털 환경의 특성을 구분하고 디지털 환경의 특성이 소비자의 문화콘텐츠 구매의도에 어떠한 영향을 주는 가를 확인하고자 하였다. 두차례의 설문조사를 실시하여 첫 번째 연구에서는 SNS를 사용하는 디지털 환경 특성을 정리하였고 이를 바탕으로 두 번째 연구에서는 구조방정식을 이용하여 디지털 환경 특성과 소비자의 정보적 참여 및 감정적 애착, 소비자 구매의도의 관계를 확인하였다. 연구 결과 디지털 환경의 특성으로 정보적 상호작용성, 정보적 연결성, 정보적 신뢰성을 확인하였고 이는 소비자의 정보적 참여를 촉진하며 소비자의 문화콘텐츠에 대한 감정적 애착에 영향을 주고 궁극적으로 문화콘텐츠의 관람의도에 긍정적인 영향을 주는 것으로 나타났다.

본 연구에서는 정보사회에서의 정보문제와 정보교육의 문제를 체계와 생활세계라는 사회과학의 상호 경쟁적 패러다임을 통해서 분석하였다. 정보문제와 관련해서는 정보와 정보기술의 패러독스, 기회의 패러독스, 정보의 참조문제와 타당성문제가 다루어졌으며, 정보교육과 관련해서는 정보자주성과 정보소양이 논의되었다. 본 연구의 결론은 정보교육이 개인적 정보문제의 합리적 해결과 사회적 정보문제의 합리적 통제 사이의 갈등 현상을 치유하기 위한 문화적 중재요청이라는 것이다. 그리고 정보교육의 목표는 지식 자주성이 아니라 정보 자주성이어야 하며, 정보 자주성은 컴퓨터소양이 아니라 정보소양을 통해 형성된다는 점이 강조되었다.

The robot has recently emerged as a factor in the daily lives of humans, taking the form of a mechanical pet or similar source of entertainment. A robot system that is designed to co-exist with humans, i.e., a coexistence-type robot system, is important to be "it exists in various environments with the person, and robot system by which the interaction of a physical, informational emotion with the person etc. was valued". When studying the impact of intimacy in the human/robot relationship, we have to examine the problems that can arise as a result of physical intimacy(coordination on safety in the hardware side and a soft side). Furthermore, We should also consider the informational aspects of intimacy (recognition technology, and information transport and sharing). This paper reports the interim results of the research of a system configuration that enhances the physical intimacy relationship in the symbiosis of the human and the robot.

Many companies are now trying to utilize SNS (social network service) by building it as marketing communication platform that delivers marketing messages and builds customer relationship. This study investigates the factors affecting consumers' intention to use of brand's SNS identity page (e.g., fan page in Facebook). It specifically focuses on four social support functions -self-esteem, informational, emotional and social networking support-in virtual space. Research model attempts to explore the impact of social supports on brands' SNS identity page adoption with modified technology acceptance model which includes perceived usefulness, ease of use and enjoyment. Empirical study adopts SEM (structural equation modelling) to test research model. The result indicates that perceived ease of use is influenced by informational support, and perceived usefulness is influenced by informational, emotional, and self-esteem support. And perceived enjoyment is influenced by emotional support. In addition, it reveals that there were no significant effects of social networking support on both perceived usefulness and enjoyment. These findings provide managerial implications for attracting potential and actual customers to brand's SNS identity page. And it also suggests the importance of managing sociability in brand's SNS identity page to make it as marketing communication platform.

The purpose of this research is to analyze ‘consumer education system in middle school’, whether it is suitably organized to help students make the right decision in their daily life as a rational consumer in this fast changing “the Informational Society”. We divided the consumer education of “the Informational Society” into 4 fields of studies(consumer information technique, decision making on purchasing, consumer financial management, and consumerism) and made specific analysis for this research. The “Technology & Home Economics” textbook which follows ‘The 7th curriculum’ conducted by “Korean Educational Board” Ministry of Education & Human Resources Development for first and second grade in middle school were used for this analysis. The results founded are as follows: first, for the curriculum analysis according to the 4 fields of consumer education, both the first and the second grade students' textbook had consumer information technique as the major portion of the consumer education. Second, as a result of the comparison between the two grade levels showed that the second grade level has higher portion of consumer education in “Home economics & Technology” textbook than the first grade level. Third, the present status of consumer education showed that the first grade level's consumer education was only limited in consumer information technique, but the second grade level's consumer education was ranging evenly throughout the 3 fields of consumer education: consumer information technique, decision making on purchasing and consumerism. These results of this study contribute to the development of an efficient and desirable curriculum for the adolescent' consumer education, specially for school consumer education, in “the Informational Society”.

This study analyzes gender bias in children's informational books about science and science careers to determine how these early resources are affecting the disparity between males and females in science and engineering fields. The study focused on the number of male and female scientists both in pictures and text, and how much space was devoted to discussion of scientists of each gender. Overall, the findings of the study show that only 18% of the pictured scientists were female as well as only 16% of the scientists discussed in the text. These numbers are below current industry data that puts the number of females working in science and engineering fields at 26%.
