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.

Bacterial contamination is an unavoidable finding of the semen collection process in boar and can lead in deleterious effects on semen quality and longevity if left uncontrolled. The purpose of this study is to identify the bacteria in extended boar semen and to select the effective antimicrobials to control of the contaminants. Of 116 extended boar semen samples submitted from eight AI centers in Korea, 39 (33.6%) samples were positive for bacterial contamination. Among 39 contaminated semen, most of them (84.6%) were contaminated with one or two bacterial species and there was no significant difference between two age groups $(\leq\;24\;and\;>\;24\;month\;old).$ Stenotrophomonas maltophilia (n = 18) was the most predominant bacterium followed by Elizabethkingia meningoseptica (n = 12), Sphingomonas paucimobilis (n = 12), Myroides spp. (n = 5), Ochrobactrum anthropi (n = 3), and so on. Enrofloxacin (72.9%), florfenicol (72.9%), bacitracin (49.2%) and tylosin (49.2%) showed higher sensitivity compared with penicillin (13.6%) or aminoglycosides (6.8%-18.6%). Brucella spp., Leptospira spp., Mycoplasma hyopneumoniae, Mycoplasma hyorhinis, Mycobacterium tuberculosis complex were not detected in semen by PCR.

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.

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.

Prosthodontic decision-making process is done through analysis of clinical information and mutual communication between patient and dentist. When opposing teeth are extruded due to missing tooth or tooth defects, selection of appropriate treatment plan and predictory prognosis can be complicated in functional rehabilitation. In case of severely disharmonious occlusal plane result from extruded teeth, re-establishment of the occlusal plane is required, if necessary via prudent evaluation. In this case, class III patient had unesthetic appearance and mastication discomfort caused by disharmonious occlusal plane due to severe extrusion. Through a structured diagnostic process, appropriate treatment plan was selected. Esthetic and functional results were obtained through from full mouth rehabilitation with re-establishment of the occlusal plane. 보철 치료계획 결정과정은 임상정보에 대한 치과의사의 분석과 환자와의 상호소통을 통하여 이루어진다. 치아의 상실이나 치관부 결손으로 인해 발생한 공간으로 반대악 치아가 정출된 경우, 구강기능을 회복시키는데 있어 적절한 치료방법 선택 및 예후를 예측하는데 혼란이 야기될 수 있다. 치아의 정출로 인한 교합평면의 심한 부조화가 나타난 경우, 신중한 평가가 필요하며, 필요 시 교합평면을 재설정 해야 한다. 본 증례는 심한 정출에 의한 불균일한 교합평면과 class III 악간관계로 인한 비심미성 및 저작불편을 주소로 내원한 환자로, 체계적인 진단과정을 통한 치료계획의 수립으로 교합평면 재설정을 통한 전악수복으로 심미적이고 기능적인 결과를 얻었기에 보고하는 바이다.

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.

본 연구에서는 마인드셋의 긍정적 역할과 객실승무원 스트레스 관리의 필요성을 인식하여 마인드셋이 스트레스, 직무성과에 미치는 영향관계을 분석하고자 하였다. 분석을 위해 K 항공사에 재직 중인 객실승무원을 대상으로 설문을 실시하였으며, 총 266부를 최종분석에 사용하였다. 연구의 가설을 검증하기 위해 설문을 바탕으로 빈도분석, 탐색적 요인분석, 신뢰도 분석, 확인적 요인분석, 측정모형분석, 측정모형의 타당도 검증, 구조방정식 모형분석을 하였다. 분석결과는 다음과 같다. 첫째, 마인드셋은 객실승무원의 스트레스 하위요인인 역할 스트레스, 보상 스트레스, 관계스트레스에 모두 부(-)의 영향을 미치는 것을 확인하였다. 둘째, 객실승무원의 스트레스가 직무성과에 미치는 영향을 살펴본 결과 보상 스트레스는 직무성과에 부(-)의 영향을 미치는 것으로 나타났다. 반면에 관계 스트레스는 직무성과에 긍정적인 영향관계를 확인하였으며, 역할 스트레스와의 관계에서는 유의미한 결과를 갖지 못하였다. 셋째, 마인드셋은 직무성과에 유의미한 긍정적 영향관계를 나타냈다. 이러한 연구결과는 마인드셋의 긍정적인 효과를 확인하고 조직성과에 기여함을 나타내는 결과이다. 또한, 항공사 객실승무원의 마인드셋 변화를 위한 프로그램을 마련하고 실전 업무에서 적용될 수 있도록 해야 할 것이다. The purpose of this study is to analyze the influence of the mindset on stress and job performance. For the analysis, a questionnaire is conducted for cabin crew members in K airlines, and a total of 266 copies are used for the final analysis. To verify the hypotheses of the study, frequency analysis, exploratory factor analysis, reliability analysis, confirmatory factor analysis, measurement model analysis, validation of the measuremen model, and structural equation model analysis are used based on the questionnaire. First, it is confirmed that the mindset had a negative (-) effect on the cabin crew's role stress, reward stress and relationship stress. Second, it is found that cabin crew's reward stress have a negative (-) effect on job performance. On the other hand, relationship stress is found to have a positive influence on job performance and there is no significant result in effect with role stress. Third, the mindset showes a significant positive impact relationship on job performance. As a result, it is necessary to introduce a mindset intervention program so that it can be applied in practical work. These research results confirm the positive effects of mindsets and show that they contribute to organizational performance. In addition, it is necessary to prepare a program to change the mindset of airline cabin crew and to be applied in actual work.
