The purpose of this study was to provide basic data for future research and suggest product development and market segmentation strategies by identifying the perceptions and consumption behaviors of vegetarians in each segment of the vegetarian market. According to food consumption value, a total of three market segments were derived, and the markets were named based on their characteristics, including 'environment and animal protection', 'multiple consideration' and 'low interest'. As a result of analyzing the perception of vegetarian-based food, "environment and animal protection" and "multiple consideration" presented positive perceptions of a vegetarian food product. Conversely, the group stating low interest expressed negative perceptions of the vegetarian food product. An analysis of the requirements for development for vegetarian-based foods products (eg. aquafaba), indicated that the development requirements for all products, except cultured and processed meats, were high.?Considerable demand was observed for vegetarian menus and vegetarian restaurants. As a result of the analysis on the necessity of the elements of the vegetarian restaurant menu, the subjects that stated "multiple consideration" had significantly higher awareness of issues related to vegetarian foods than others.

옛한글로 저술된 자료는 활자 인쇄본, 목판 인쇄본, 필사본, 고소설, 서간 등 방대한 자료가 한국학중앙연구원 장서각을 비롯하여 많은 기관에 소장되어 있다. 옛한글을 전산정보화하기 위해서는 수작업에 의한 '입력'과정이 필요하다. 옛한글 문서의 전자문서화 작업이 오랫동안 진행되어 왔으나 옛한글을 전공한 연구자 개인의 노력으로 옛한글을 읽고 입력하여 전자자료화되고 있는 실정이다. 연구자의 숙련도가 개인적인 작업능력의 향상에 머무르고 기술의 축적으로 이어지지 못한다. 현재까지 극히 일부분의 옛한글 문서만이 소개되고 대부분의 자료는 수장고에 보관되어 있는 상태이다. 어렵게 전자문서화된 옛한글 고문서도 전자기기 간의 호환성 문제로 정보 공유 및 표시에도 어려움이 있다. 옛한글 문서의 전자문서화의 작업효율을 높이고 전자문서화 기술의 축적을 위해서는 옛한글의 입력, 표시, 저장 방법의 개선을 비롯하여 옛한글 문서의 이미지 분석을 통한 광학적 문자인식(OCR)의 개발이 필요하다. A vast amount of materials-such as prints, woodblock prints, manuscripts, old novels, and letters-written in old Korean and using old grammar and/or obsolete characters, are collected in many institutions, including the Jangseogak at the Academy of Korean Studies. Digitization of these texts has required a prolonged manual inputting process. Individual researchers, who majored in old Korean, have read and typed the characters into electronic documents, which depends upon individual skill, effort, and approach, and is particularly limiting because none can be significantly increased. To date, only a small proportion of the old Korean document collections, currently kept in storage, have been digitized and made available to the public. Even the electronic formats of the texts prove difficult to displaying correctly, due to the incompatibility between the old Korean characters and the character set on today's electronic devices. To improve the techniques and efficiency of digitizing old Korean texts, it is necessary to develop optical character recognition (OCR), which will analyze images of old Korean documents, as well as input, display, and storage methods.

This paper describes a naturally occurring case of meningoencephalitis associated with Listeria monocytogenes in a 4 month-old Korean native goat. The goat was raised in a herd consisting of seventy goats, and fed on straw and leftover vegetables including onions, cauliflower, and bean sprouts. The clinical symptoms of the goat were depression, in appetence, anorexia, circling, and recumbency before death. No conspicuous gross lesions were found except consolidation of the lung. Histopathologically, severe multifocal microabscesses and perivascular cuffings were observed in the brain stem and mid brain. In addition, mild nonsuppurative meningitis in the cerebrum were seen in this case. The organism isolated from the brain stem was confirmed as L. monocytogenes using the biochemical tests and PCR assay. Based on clinical signs, histopathology, and bacterial isolation; we confirmed that this case was a typical encephalitic listeriosis.

The relationship between night cooling rate and meteorological elements was investigated over the past five years (2016-2020), using weather data from the new (Daegu(143)) and old (Shinam(860)) Daegu Regional Meteorological Agency located in the suburban and urban regions, respectively. There was a correlation between the total daily amount of solar radiation (S_tot) and the night cooling rate in the both regions. However, a higher correlation was observed at the new Daegu Regional Meteorological Agency station (Daegu(143)). In particular, data from the new Daegu Regional Meteorological Administration's observatory, which experiences a low thermal storage effect caused by artificial structures, showed a higher correlation between nighttime cooling and weather factors. The reason for this is that the lesser the heat storage effect caused by the artificial structures, the better the effect of surface radiation cooling on temperature reduction. These findings confirm that the correlation between night cooling and weather factors can be used to assess the impact of artificial structures in cities.
