  • Purpose: This study was done to identify the relationship of emergency department(ED) nurse's job characteristics, organizational commitment and turnover intention. Method: This study was conducted through a survey of 171 nurses from ED in nine general hospitals of Band U cities. The data were collected by self-report questionnaires and analyzed with the SPSS WIN 17.0 program using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient and stepwise multiple regression. Results: The mean score for job characteristics was 3.37. Job characteristics according to position, number days night duty, and monthly income showed significant differences. Turnover intention according to age, total career, and monthly income showed significant differences. A significant positive correlation was found between job characteristics and organizational commitment. Significant negative correlations were found between job characteristics and turnover intention, organizational commitment and turnover intention were found. The significant factors influencing turnover intention were organizational commitment, monthly income, and total career, which explained 27.6% of the variance. Conclusion: The findings indicate that nurse managers should analyze the reasons for high turnover intention, focusing on the main factors affecting turnover intention and consider solutions for decreasing turnover intention.

  • Collaborative consumption (CC) occurs in organized systems or networks in which participants conduct sharing activities in the form of renting, lending, trading, bartering, and swapping of goods, services, transportation solutions, space, or money. Information and communications technologies (ICTs) that have emerged with CC. CC is expected to alleviate social problems such as hyper-consumption, pollution, and poverty by lowering the cost of economic coordination. In this study, we investigate the influence of educational experience and expected benefits of CC participation (intended to using and providing CC) of Adolescent Consumers. The subjects for the study were 418 high school students. Data was analyzed through frequency analysis, mean, standard deviation, t-test, ANOVA, Pearson's correlation, and hierarchical multiple regression analysis using SPSS Win 21.0. The results of this study are as follows. First, the significant positive relationship found between CC participants (intent to use and provide CC), educational experience (home education, school education, and mass media) and expected benefits (social benefit, economic benefit, enjoyment, community effect, and reputation). Second, enjoyment, mass media, reputation, social benefit, home education and school education values were variables that influenced the using participation intention for CC. Third, the major variables influencing the providing participation intention CC were home education, enjoyment, gender, community effect, and mass media values.

  • A system Integrator (SI) makes a consortium with multiple providers of hardware and software solutions to sell an information system. The success of information systems (IS) mainly depends on establishing a trustful relationship between SI supplier and client, and delivering high-quality system. However, the determinants of trust and system quality have been investigated mostly from the perspective of s ystem buyers rather than system sellers. This study examines the influence of key variables that SI can handle to improve trust and system quality which finally leads to user satisfaction toward SI. This study adopts resource complementarity, user participation and information sharing as the key variable then builds a research model to explain their relationships to user satisfaction. Respondents are recruited from 251 firms that have built any information system in recent two years in South Korea. Results of partial least square (PLS) modeling analysis show that both resource complementarity and information sharing have positive relationships with trust. Also the relationships between trust, system quality and user satisfaction toward S.I are supported. In addition, the mediating roles of trust and system quality are identified. We discussed some of the key managerial and theoretical implications of the paper and suggested further research directions.

  • Background: Vibrio parahaemolyticus is one of the most common causes of seafood-borne illnesses in Korea, either directly or indirectly, by consuming infected seafood. Many studies have demonstrated the antibiotic susceptibility profile of V. parahaemolyticus. This strain has developed multiple antibiotic resistance, which has raised serious public health and economic concerns. This article reviews the food-borne outbreaks, distributions, virulence, and antibiotic resistance profiles of V. parahaemolyticus in Korea during 2003-2016. Main body: V. parahaemolyticus infections appeared to be seasonally dependent, because 69.7% of patient infections occurred in both August and September during 2003-2016. In addition, the occurrence of V. parahaemolyticus in marine environments varies seasonally but is particularly high in July, August, and September. V. parahaemolyticus isolated from aquaculture sources on the Korean coast varied in association with virulence genes, some did not possess either the tdh (thermostable direct hemolysin) or trh (tdh-related hemolysin) genes, and a few were positive for only the trh gene or both genes. The high percentage of ampicillin resistance against V. parahaemolyticus in the aquatic environment suggests that ampicillin cannot be used to effectively treat infections caused by this organism. Short conclusion: This study shows that the observed high percentage of multiple antibiotic resistance to V. parahaemolyticus is due to conventionally used antibiotics. Therefore, monitoring the antimicrobial resistance patterns at a national level and other solutions are needed to control aquaculture infections, ensure seafood safety, and avoid threats to public health caused by massive misuse of antibiotics.

  • Objectives: The purpose of this study was to understand the level and patterns of college adjustment, major satisfaction, academic engagement, and attention deficit hyperactivity disorder (ADHD). This study examined the factors influencing adaptation to college life. Methods: This study was approved by the institutional review board of 00 university. We analyzed 166 survey data responses collected by distributing questionnaires from June 1 to July 2, 2020. Statistical product and service solutions version 23.0 was used for statistical analyses. The data were presented as frequencies and percentages or means and standard deviations, and pearson correlation analysis and multiple regression analysis were performed. Results: There was a significant difference in the average score of major satisfaction according to the type of college (university) and grades. For college adjustment, there was a significant difference in the average score according to major grades. Academic engagement showed a significant difference in the average score according to the college type and grade. Major satisfaction, college adjustment, and academic motivation showed significant positive correlations among the variables, whereas ADHD, major satisfaction, and college adjustment showed a significant negative correlation. Multiple regression analysis revealed that major satisfaction (p<0.001) and academic motivation (p<0.001) were factors affecting college adjustment (p<0.05). Conclusions: It is necessary to develop and apply specific and systematic adaptation programs to improve the understanding, control, and guidance methods for college students and to promote human relations, such as school life and social life.

  • 소상공인이 한국 경제에서 차지하는 비중이 높지만 전문적인 경영 역량이 부족하여 어려움에 처하는 경우가 많다. 그러나 이에 대한 실효성 있는 대안은 부족하다. 소상공인의 경영 문제에 관한 학계의 관심은 주로 성공적인 소상공인의 특징을 밝히거나 요인들 간의 관련성을 살펴보는 기술적이고 정량적 데이터 위주의 단편적 성과에 머물렀다. 한편 실질적인 경영 지원 과정을 통해 획득된 지식과 경험들을 이론적으로 논의하는 실천적 연구 성과는 찾아보기 어려운 형편이다. 2015년 6월부터 2015년 11월까지 경기도에 소재한 소상공인 업체들과 경기도 소재의 대학 및 경기도 소재의 중소기업진흥 기관이 공동으로 추진한 컨설팅 프로젝트에 실행 연구법을 부분 적용한 결과 트리플 힐릭스 이론 기반의 소상공인 컨설팅이 바람직한 결과를 가져온다는 사실을 알 수 있었다. 업체와 대학 그리고 공공 기관의 협업은 경영학을 배우는 학생들의 문제의식을 높이고 지식을 활용하는 기회를 부여하는 등 경영교육 상 목적 달성에 적절함도 확인했다.

  • 연성 콘택트렌즈 종류의 하나인 일회용 렌즈는 사용상 편리함을 주는 반면 다양한 안과적 감염성 질환을 초래한다. 안 질환을 유발하는 미생물로는 Acanthamoeba, Bacteria, Fungi 등이 있다. 렌즈 착용시 손을 이용함으로 다양한 미생물 오염은 근절이 불가피한 실정이다. 다양한 미생물의 오염으로 인해 감염성 각막염을 유발하나 정확한 미생물 동정은 미비한 상태이다. 이런 이유로 렌즈를 세척하기 위해 흔히 사용하는 식염수와 ReNu Solution (Bausch and Lomb Company, USA)의 2그룹으로 나누고 식염수와 ReNu Solution을 사용하여 1, 3, 5 10 그리고 15일에 따라 미생물 오염의 정도를 살펴보고 분리되는 미생물을 동정하고자 하였다. 대구시 D대학 안경광학과 재학생들의 안과적 건강상태를 조사한 후 그룹별 10명씩 지정하였다. 일일 착용렌즈를 1일, 3일, 5일 10일, 그리고 15일에 따라 사용 후 배지에서 세균을 배양하였다. 배양된 집락을 선택하여 그람 염색한 결과, Gram-positive cocci 33%, Gram-negative cocci 2%, Gram-positive bacilli 34%, 그리고 Gram-negative bacilli 31%로 나타냈고 이러한 세균을 동정하기 위해 API kit와 VITEK system을 이용하였다. 그 결과 콘택트렌즈의 착용에 의해 유발되는 각막염의 원인세균으로 알려진 S. aureus, P. aeruginosa 등이 분리되었다. 본 연구에서는 연성렌즈의 하나인 일일 착용렌즈의 착용시 세척액에 따른 일반세균의 분포와 일회용 렌즈의 연속 착용에 따른 병원성 세균을 조사함으로 콘택트렌즈의 사용시 위생의 필요성을 시사한다.

  • After observing that most tourists plan to complete their visits to multiple cultural heritage sites within one day, we surmised that for many museum visitors, the foremost thought is with regard to the amount of time is to be spent at each location and how they can maximize their enjoyment at a site while still balancing their travel itinerary? Recommendation systems in e-commerce are built on knowledge about the users' previous purchasing history; recommendation systems for museums, on the other hand, do not have an equivalent data source available. Recent solutions have incorporated advanced technologies such as algorithms that rely on social filtering, which builds recommendations from the nearest identified similar user. Our paper proposes a different approach, and involves providing dynamic recommendations that deploy social filtering as well as content-based filtering using term frequency-inverse document frequency. The main challenge is to overcome a cold start, whereby no information is available on new users entering the system, and thus there is no strong background information for generating the recommendation. In these cases, our solution deploys statistical methods to create a recommendation, which can then be used to gather data for future iterations. We are currently running a pilot test at Chao Samphraya national museum and have received positive feedback to date on the implementation.
