Objectives: Bioterrorism (BT) preparedness and response plans are particularly important among healthcare workers who will be among the first involved in the outbreak situations. This study was conducted to evaluate the current status of education for BT preparedness and response in health care-related colleges/junior colleges and to develop learning objectives for use in their regular curricula. Methods: We surveyed all medical colleges/schools, colleges/junior colleges that train nurses, emergency medical technicians or clinical pathologists, and 10% (randomly selected) of them that train general hygienists in Korea. The survey was conducted via mail from March to July of 2007. We surveyed 35 experts to determine if there was a consensus of learning objectives among healthcare workers. Results: Only 31.3% of medical colleges/schools and 13.3% of nursing colleges/junior colleges had education programs that included BT preparedness and responses in their curricula. The most common reason given for the lack of BT educational programs was 'There is not much need for education regarding BT preparedness and response in Korea'. None of the colleges/junior colleges that train clinical pathologists, or general hygienists had an education program for BT response. After evaluating the expert opinions, we developed individual learning objectives designed specifically for educational institutions. Conclusions: There were only a few colleges/junior colleges that enforce the requirement to provide education for BT preparedness and response in curricula. It is necessary to raise the perception of BT preparedness and response to induce the schools to provide such programs.

Apple white rot, caused by Botryosphaeria dothidea, is one of the important diseases in Korea. B. dothidea can cause pre- and postharvest decay on apple fruit as well as canker and dieback of apple trees. In this study, we isolated bacteria from the trunk of apple trees and tested their antagonistic activity against B. dothidea. Five bacterial isolates (23-168, 23-169, 23-170, 23-172, and 23-173) were selected that were most effective at inhibiting the mycelial growth of the pathogens. The isolate 23-172 was identified as Bacillus amyloliquefaciens and four isolates 23-168, 23-169, 23-170, and 23-173 were identified as Bacillus velezensis by RNA polymerase beta subunit (rpoB) and DNA gyraseA subunit (gyrA) gene sequencing. All isolates showed strong antagonistic activity against B. dothidiea as well as Colletotrichum fructicola and Diaporthe eres. All isolates exhibited cellulolytic, proteolytic and phosphate solubilizing activities. In particular, two isolates 23-168, 23-169 were shown to significantly reduce the size of white rot lesions in pretreated apple fruits. These results will provide the basis for the development of a fungicide alternative for the control of white rot of apple. 본 연구에서는 사과 겹무늬썩음병을 유발하는 Botryosphaeria dothidea를 억제하는 길항미생물을 선발하였고, 선발한 길항미생물의 항균 활성과 길항 효소 생성 여부를 확인하였다. 선발된 길항미생물 중 4종은 Bacillus velezensis로 동정되었고, 1종은 B. amyloliquefaciens로 동정되었으며 이 길항미생물은 모두 겹무늬썩음병균에 강한 항균 활성을 가지고 있었다. 또한 선발된 5종의 길항미생물은 탄저병균인 Colletotrichum fructicola, 줄기마름병인 Diaporthe eres도 효과적으로 균사생장을 억제하였다. 선발된 길항미생물을 대상으로 cellulase, protease, phosphate solubilization 효소 활성을 분석한 결과 모두 효소를 분비하여 병원균의 생장을 억제 및 사멸시키고 식물 생장촉진 활성을 가지는 것으로 확인되었다. 사과 과실에서 겹무늬썩음병균과 선발된 길항미생물을 동시 접종하여 발병 억제 효과를 검정한 결과 B. velezensis 23-168 균주가 가장 효과적으로 발병을 억제하였다. 따라서 선발된 5종의 길항미생물은 사과 진균 방제를 위한 기초자료로 사용할 수 있을 것으로 생각된다.

The effect of touch simulation in virtual reality shopping

이하경,윤남희,최두영 한국의류학회 2022 Fashion and Textiles Vol.9 No.1

This study aims to explore the efect of touch simulation on virtual reality (VR) store satisfaction mediated by VR shopping self-efcacy and VR shopping pleasure. The moderation efects of the autotelic and instrumental need for touch between touch simulation and VR store satisfaction are also explored. Participants wear a headmounted display VR device (Oculus Go) in a controlled laboratory environment, and their VR store experience is recorded as data. All participants’ responses (n=58) are analyzed using SPSS 20.0 for descriptive statistics, reliability analysis, exploratory factor analysis, and the Process macro model analysis. The results show that touch simulation positively infuences VR store satisfaction, which is mediated by the self-efcacy and by the dual path of the self-efcacy and the pleasure. Furthermore, the relation between touch simulation and pleasure is moderated by need for touch. For individuals with a high level of autotelic need for touch, the efect of touch simulation on the pleasure is heightened. However, instrumental need for touch does not moderate the path of touch simulation on the self-efcacy.

개인의 기술혁신성과 감각추구성향이 테라피적 메타버스 사용에 미치는 영향

이하경,최두영 한국생활과학회 2023 한국생활과학회지 Vol.32 No.2

본 연구에서는 개인의 내재적 특성인 기술혁신성과 감각추구성향이 테라피적 메타버스 사용에 미치는 영향력을 규명하였다. 또한 기술혁신성과 감각추구성향이 테라피적 메타버스 사용 동기에 미치는 영향력을 아바타와의 동일시 수준이 조절하는 것을 실증적으로 검증하였다. 제페토(Zepeto) 사용자 304명을 대상으로 데이터를 수집하였으며 수집된 데이터는 AMOS 25.0을 사용하여 기술통계, 확인적요인분석, 구조방정식모형 분석을 실시하였다. 분석 결과, 개인의 기술혁신성은 테라피적 메타버스 동기나 메타버스 테라피 결과에 영향을 미치지 않았으나 감각추구성향은 테러피적 메타버스 동기를 매개하여 메타버스 테라피 결과에 영향을 미치는 것으로 나타났다. 다음으로 아바타 동일시의 조절효과를 검증한 결과, 감각추구성향이 테라피적 메타버스 동기에 미치는 영향력은 아바타 동일시 수준에 따라 달라지지 않았으나, 기술혁신성이 테라피적 메타버스 동기에 미치는 영향력은 아바타 동일시 수준에 따라 달라지는 것으로 나타났다. 특히, 아바타 동일시 수준이 높을 때에만 기술혁신성이 테라피적 메타버스 동기를 매개하여 메타버스 테라피 결과에 영향을 미치는 것으로 나타나 조절된 매개효과를 확인하였다. 본 연구에서는 메타버스 수용 후 이를 소비하면서 겪을 수 있는 소비자의 심리적 혜택을 탐색함으로써 메타버스가 지니는 새로운 순기능을 밝히고 관련 연구의 범위를 확장하였다는 의의를 지닌다. 또한 메타버스 경험이 심리적 테라피로 사용될 수 있다는 본 연구 결과를 토대로 브랜드에서는 메타버스 공간에 스토어를 마련할 때 소비자가 기분전환을 할 수 있는 콘텐츠를 준비함으로써 차별적 가치를 제공할 수 있을 것이다.

이하경,윤소연,김하빈,권현진,강효정,허희진,이미아,전대근 한국마케팅과학회 2015 Journal of Global Fashion Marketing Vol.6 No.1

This study examines consumer attention to and the perceived aesthetics of sale signs,such as the designs (size and color) of the Point of Purchase (POP) sale signs outsideshops, and how these factors affect consumer intention to visit a shop based onexpectation regarding the stores. External store stimuli were created using the Sketchup8 software package. Research found that influences on intention to visit a store candiffer depending on how the sale signs are perceived. Consumer expectations of thestore can differ depending on the size of sale signs and the colors employed. We expectthat the outcomes of this study will aid fashion brands in designing sale signs thatreflect their brand value and image. Sale sign planning and utilization as a part of thestrategy will be the key factor that can affect consumer behavior.

The purpose of this study reveals the changes seen in brainwaves when middle school students look at several pictures, and descriptions written in lies. It also shows the differences between their brainwaves seen when looking at lies, and looking at the truth, which may be used further in criminal investigation. This study shows that people looking at lies have a high change in their alpha waves and theta waves, and therefore predicted to feel high anxiety.

패션상품 챗봇에 대한 신뢰 형성 요인 - 지각된 지능과 긍정적 인지의 매개효과를 중심으로 -

이하경,윤남희 한국의류산업학회 2022 한국의류산업학회지 Vol.24 No.2

This study explores the effect of anthropomorphism on fashion chatbot reliability, mediated by perceived intel- ligence and cognitive evaluation. The moderating effects of individuals’ need for human interaction between chatbot anthro- pomorphism and perceived intelligence, cognitive evaluation, and chatbot reliability are also explored. Participants, who were recruited through the online research firm, responded to questions after watching a video clip showing a conversation with a fashion chatbot on a mobile screen. The data were collected through Mturk, a crowdsourcing platform with an online research panel. All responses (N = 212) were analyzed using SPSS 26.0 for the descriptive statistics, frequency analysis, reli- ability analysis, exploratory factor analysis, and PROCESS procedure. The results demonstrate that chatbot anthropo- morphism increases chatbot reliability, and this is mediated by chatbot intelligence. Although chatbot anthropomorphism increases cognitive evaluation, the effect of cognitive evaluation on chatbot reliability is not significant; thereby, the effect of chatbot anthropomorphism on chatbot reliability is not mediated by the cognitive evaluation. The direct effect of anthro- pomorphism on chatbot reliability is also moderated by individuals’ need for human interaction. For participants with a high need for human interaction, chatbot anthropomorphism increases chatbot reliability; however, anthropomorphism does not sig- nificantly affect chatbot reliability for participants with a low need for human interaction. The study’s findings contribute to expanding the literature on consumers’ new technology acceptance by testing the antecedents affecting service reliability.

온라인 추천 상품의 제시방법이 웹사이트 이용의도에 미치는 영향 -심적 시뮬레이션의 매개효과를 중심으로-

이하경,안서원 한국의류학회 2018 한국의류학회지 Vol.42 No.6

This study tests the effect of recommended product presentation on consumers' usage intentions of a website, mediated by mental simulation. Mental simulation refers to perceptual experience, a more automatic form of mental imagery, initiated by exposure to the representations of objects. This study expects that when compliments of clothes (coordination items) are vertically presented online, consumers are likely to feel as if they wear the outfits due to the activation of mental simulation. The survey was conducted on 147 women in an age group between 20 and 40 years in a panel of an online survey firm. Data are analyzed using exploratory factor analysis and bootstrapping analysis by SPSS 20.0. The results show that when compliments (vs. substitutes) of clothes are presented, participants perceive a greater mental simulation. When compliments of clothes are vertically presented (vs. horizontally presented), mental simulation is also highly driven. In addition, mental simulation mediates the effects of online product presentation on consumers' usage intentions of a website. The findings of this study contribute to marketing strategies of online retailers in terms of how product recommendation can be offered to consumers with more psychological benefits.
