목적 : 소방공무원의 음주량과 직종별 직무 스트레스에 대해 알아보고 보다 나은 스트레스 관리방안과 문제성 음주예방을 위한 프로그램을 모색하기 위해 시도되었다. 대상 : 2000년 7월부터 8월까지 소방공무원 중 구조대원 97명, 구급대원 97명, 화재진압대원 179명,행정대원 116명, 기타대원 49명을 대상으로 설문지를 이용하여 수집된 자료를 분석하였다. 결과 : 소방공무원은 모든 직종에서 승진 및 임금제도의 스트레스 요인 점수가 가장 높았다. 직종별로 직무 내적 요인, 조직에서의 역할, 대인관계, 조직과 풍토, 직장환경과 스트레스 결과 점수에 있어 유의한 차이를 보였다 과음 주자인 경우 직무 내적요인, 직무 스트레스 수준, 개인적 특성, 대처방식의 점수가 높았으나 유의하지 알았다. 음주량은 직무내적 요인 중 업무 피드백과 음의 관련성을, 직무 스트레스 요인 중 역할 갈등은 음주량을 증가시키는 것으로 나타났다. 결론 소방공무원의 가장 높은 직무 스트레스 요인으로는 승진 및 임금제도인 것으로 나타났다. 음주량은 역할 갈등과 같은 직무 스트레스 요인과 관련이 있었으며, 향후 전향적인 음주행태조사를 통해 직무 스트레스 요인이 음주에 미치는 영향을 파악하기 위한 연구가 필요하다고 생각된다. 따라서 본 연구결과를 기초로 소방공무원의 직무 스트레스 요인에 대한 적절한 관리와 정책이 필요한 것으로 사료된다. Objectives : To establish the relationship between alcohol use and job stress among firemen, and to develop a comprehensive health promotion program including stress management and the prevention of problem drinking. Methods : Data was collected from July to August, 2000. Study subjects included 97 rescue workers, 97 emergency medical personnel, 179 fire extinguishers, 116 administrators and 49 others. Results : The firemen displayed higher scores of stress due to promotion-related pres-sures and salary. We found significant differences in job internal factors, job role, inter-personal relationship, organizational norm, work environment and stress outcome among the various jobs. Job internal factors, job stress factors, personal characteristics, coping skills, and stress outcome were higher in heavy drinkers compared with the light and moderate drinkers. Job internal factors and smoking habit showed a positive correlation with the amount of drinking, although coping skill, exercise frequency and monthly income showed a negative relation with the amount consumed. Conclusion : This study suggested that alcohol drinking is associated with job stress. This suggests that a comprehensive health promotion program including stress management and problem drinking prevention and control should be developed.

Expediting the Formation of Cellulose Nanopaper by Heterocoagulation of Oppositely Charged Cellulose Nanofibers

Meng Kang,Chenglong Li,Dehai Yu,Guodong Li,Zhaoping Song,Huili Wang,Wenxia Liu 한국섬유공학회 2022 Fibers and polymers Vol.23 No.7

Cellulose nanopaper has attracted tremendous attention as an alternative to fossil-based flexible substrates. However, the fabrication of nanopaper from cellulose nanofibers (CNFs) is a time-consuming process. Herein, positivelycharged CNFs (PCNFs) were employed to heterocoagulate negatively charged CNFs (NCNFs) at various PCNF-to-NCNFratios in order to decrease the formation time of nanopaper. At a PCNF-to-NCNF ratio of 1:1, the formation time was reducedfrom 98 min to 20 min. Although heterocoagulation increases the roughness of cellulose nanopaper, nanopapers made from amixture of NCNFs and PCNFs still possess a nanosized network structure and therefore show similar transparency tonanopapers made of pure NCNFs. Compared to the nanopaper made from pure NCNFs, the nanopaper made from themixture of NCNFs and PCNFs showed reduced tensile strength but improved resistance to deformation. This study providesa practical method for the production of cellulose nanopaper.

MSP1 triggers cell death and defense response in rice

Qingfeng Meng,Yiming Wang,Kyu Young Kang,Ravi Gupta,Sun Tae Kim 한국육종학회 2015 한국육종학회 심포지엄 Vol.2015 No.07

When the rice blast fungus attacks rice, fungal proteins are secreted into the plant apoplast to facilitate infection. The rice plant recognizes such secreted proteins, which result in the induction of defense responses. However, the molecular mechanisms of how rice plant recognizes secreted proteins remain elusive. Here, we report that a small, secreted protein, Magnaporthe oryzae snodprot1 homolog (MSP1), is recognized by rice plants and triggers host cell death and defense responses. Furthermore, pre-treatment of rice with Domain II, elicitor-active epitope of MSP1, induces resistance to the pathogen KJ301. We demonstrated that secretion of MSP1 into the apoplast is prerequisite for triggering cell death and activating defense-related gene expression, suggesting that it is recognized by a receptor in the host plasma membrane. Through comprehensively analysis of transcriptional profile in rice leaves and suspension cultured cells (SCCs) in response to exogenous MSP1 and Domain II treatment using 60K Agilent microarray chip, we found that 27 signaling genes, such as F-box(6), MAPK(4), protein kinase(11), transcription factor(6), were up-regulated in leaves and SCCs and six protein kinases were targeted into plasma membrane. Thus, we suggest that some of these genes may act as receptor of MSP1 in response to exogenous MSP1 treatment. Expression pattern of candidate genes was further checked in response to different environment cues using open rice data. These results demonstrate that these genes may be also involved in the signaling in response to cold stress, root-JA treatment and brown plant hopper (BPH) attack.

코로나19 이후 도시관광 선택속성이 만족도 및 재방문 의도에 미치는 영향 : 중국 상해를 중심으로

장멍멍 ( Zhang Meng-meng ),김진강 ( Kim Jin-kang ) 동북아관광학회 2023 동북아관광연구 Vol.19 No.1

21세기는 전염병의 시대가 되었다. 전 세계적 전염병의 확산으로 국가 간 이동이 제한되고 유동 인구가 감소하였으며 이에 따라 관광수요도 꾸준히 감소했다(백방림, 2021). 코로나19 대유행이 장기화함에 따라 관광 분야의 사회적, 경제적 타격이 심화하고 있다(송혜민·김홍범, 2022). 현재 코로나19가 세계적인 전염병으로 확산한 만큼 국제 관광시장이 전면 회복되기까지는 상당한 시간이 걸릴 것으로 보인다(손효리·김영현, 2021). 그러나 중국에서 코로나19 환경 속에서 도시관광에 관한 연구가 부족하다. 따라서 본 연구는 코로나19 환경 속에서 중국 국내 도시 상해 여행 경험이 있는 중국 관광객이 관광지를 선택할 때 도시관광 선택속성 요인에 대한 중요성과 만족, 이런 결과가 전체 관광 만족도에 미치는 영향을 파악하고 만족도가 재방문 의도에 미치는 영향을 파악하기 위한 것이다. 아울러 이런 요인을 분석해 관광산업의 이해관계자들이 코로나 환경에서 관광정책 및 마케팅 전략을 수립할 수 있는 기초자료를 제공하고자 한다. 본 연구를 위해 2021년 9월 16일부터 10월 16일까지 코로나19 환경에서 상해 여행경험이 있는 중국 관광객들을 대상으로 온라인 설문조사를 실시하였다. 총 500부의 설문지를 배포하였으며 불성실하게 응답한 설문지를 제외하고 237부를 최종 분석에 이용하였다. 연구결과, 도시관광 선택속성(매력성, 서비스품질, 접근성, 비용성, 방역수준)에서 방역수준, 매력성, 접근성과 비용성은 만족도에 유의적인 영향을 미쳤지만, 서비스품질은 만족도에 미치는 영향 유의하지 못한 것으로 나타났다. 특히 방역수준이 만족도에 미치는 영향이 큰 것으로 나타났다. 한편, 매력성, 접근성, 비용성은 만족도에 유의적인 영향을 미칠 수 있는 것으로 나타났다. 이러한 결과를 토대로 하여 학술적, 실무적 시사점을 제시하였다. The 21st century has become an era of infectious diseases. Due to the spread of infectious diseases around the world, movement between countries was restricted, the floating population decreased, and tourism demand decreased steadily(Baekbangrim, 2021). As the COVID-19 pandemic is prolonged, social and economic damage in the tourism sector is intensifying(Song Hye-min and Kim Hong-beom, 2022). Currently, as COVID-19 has spread to a global epidemic, it will take a considerable amount of time for the international tourism market to fully recover(Son Hyo-ri and Kim Young-hyun, 2021). However, in China, there is a lack of research on urban tourism in the COVID-19 environment. Therefore, this study aims to understand the importance and satisfaction of urban tourism selection attributes when Chinese tourists with experience in Shanghai, China, in the COVID-19 environment, and the effect of satisfaction on the intention to revisit. In addition, by analyzing these factors, we intend to provide basic data for stakeholders in the tourism industry to establish tourism policies and marketing strategies in the COVID-19 environment. For this study, an online survey was conducted on Chinese tourists who have traveled to Shanghai in the COVID-19 environment from September 16 to October 16, 2021. A total of 500 questionnaires were distributed, and 237 copies were used for the final analysis, excluding the questionnaires that were faithfully answered. As a result of the study, quarantine level, attractiveness, accessibility, and cost in urban tourism selection attributes(attractive, service quality, accessibility, and quarantine level) had a significant effect on satisfaction, but service quality was not significant. In particular, it was found that the level of quarantine had a large effect on satisfaction. On the other hand, it was found that attractiveness, accessibility, and cost can have a significant effect on satisfaction. Based on these results, academic and practical implications were presented.

Objective : This study was intended to examine the effects of water extract of Prunellae Spica (PS), which is a herb with 'cold' nature based on hot and cold theory of traditional Korean medicine. Methods : Hyperthyroidism was induced in SD rats by LT4 (0.5 ㎎/㎏, i.p.) daily for four weeks. After 2 weeks of LT4 injection, rats were divided randomly into four groups; normal, LT4-induced hyperthyroid control, PS extract (500 ㎎/㎏, p.o.)-treated group, and propylthiouracil (PTU, 10 ㎎/㎏, s.c.)-treated positive group. After 2 weeks of drug treatment, all rats were sacrificed and harvested blood samples and thyroid tissues. The changes of body weight, food and water intake, and body temperature were measured weekly. Serological markers were analyzed in sera using an enzyme-based assay, and thyroid tissues were stained with Hematoxylin & Eosin (H&E). Brain and dorsal root ganglion (DRG) tissues were isolated and analyzed the expression of transient receptor potential (TRP) channels by Western blot. Results : PS extract administration attenuated the loss of body weight and the increase of body temperature in LT4- induced hyperthyroidism rats. PS extract increased the level of thyroid stimulating hormone (TSH) and decreased tiiodothyronine (T3) and tetraiodothyronine (T4). In action mechanism, PS extract regulated the expression of transient receptor potential channel subfamily V member 1 (TRPV1) and transient Receptor Potential channel subfamily M member 8 (TRPM8), the thermoregulators. Conclusion : To conclude, PS extract can improve the symptoms of hyperthyroidism through regulation of the thyroid hormones imbalance and thermoregulation via TRP channels.

Meng Huan,Yun-Jeong Kang,Sang-won Lee,Dong-Oun Choi 한국인터넷방송통신학회 2021 Journal of Advanced Smart Convergence Vol.10 No.2

With the rapid development of artificial intelligence and big data, a lot of medical data is effectively used, and the diagnosis and analysis of diseases has entered the era of intelligence. With the increasing public health awareness, ordinary citizens have also put forward new demands for panic disorder health services. Specifically, people hope to predict the risk of panic disorder as soon as possible and grasp their own condition without leaving home. Against this backdrop, the smart health industry comes into being. In the Internet age, a lot of panic disorder health data has been accumulated, such as diagnostic records, medical record information and electronic files. At the same time, various health monitoring devices emerge one after another, enabling the collection and storage of personal daily health information at any time. How to use the above data to provide people with convenient panic disorder self-assessment services and reduce the incidence of panic disorder in China has become an urgent problem to be solved. In order to solve this problem, this research applies the context awareness to the automatic diagnosis of human diseases. While helping patients find diseases early and get treatment timely, it can effectively assist doctors in making correct diagnosis of diseases and reduce the probability of misdiagnosis and missed diagnosis.
