The spread of the COVID-19 pandemic has been increasing non-face-to-face activities; as a result, this has resulted in the number of individuals obtaining medical information from the websites and mobile contents of medical institutions increasing. The study conducted the structural equation modeling to test hypotheses; as a result, all sub-factors of e-service quality of small medical clinic websites and mobile contents, usability, security, responsiveness, design, and information, had a significant positive effect on relationship quality, and relationship quality had a significant positive effect on e-Loyalty. Moreover, the structural equation model showed a good model fit, χ²/df of 2.021, NFI of .954, TLI of .969, CFI of .976, RMSEA of .046. Future research is suggested to study relationship quality by developing a system able to quickly and accurately respond to websites and mobile contents users; furthermore, improving e-service quality and relationship quality is likely to strengthen e-loyalty.

X-선 혹은 감마선 등 종래의 방서선 치료는 양성자 혹은 이온에 의한 치료방법의 등장함에 따라 퇴조할 것으로 보인다. 그 이유는, 양성자 등 전하를 띄는 입자치료기술이 치료 후 후유증이나 암의 재발을 현저히 억제시킬 수 있기 때문이다. 전하를 띄는 입자는 암 조직 전후의 정상 조직에 최소한의 피폭을 주나, X-선이나 감마선과 같은 광자들은 암 조직 전후의 정상세포가 암세포로 변화될 수 있는 정도의 피폭량을 주는 것으로 알려져 있다. 현재 임상 중인 양성자(혹은 극히 일부의 탄소이온 치료기)치료기는 1990년 미국의 로마린다(Loma Linda) 대학에서 최초로 건립된 방식인 사이클로트론 혹은 싱클로트론 가속기와 빔라인 및 겐트리(gantry)로 구성된다. 그 장치의 거대함만큼이나 가격과 유지비 등에서 일반 소형병원에서 운영하기에는 쉽지 않아 보인다. 이에 본고에서는 소형병원에서도 운영할 수 있는 저비용의 레이저 양성자(이온) 가속방식의 등장 배경과 향후 전망을 논하고자 한다.

열병합 발전이란 한가지의 에너지원을 열원으로 하여 2가지 이상의 동력을 회수하는 방법을 말하며 회수에너지는 고급에너지인 전기가 주가 되고 이 때 발생되는 폐열은 회수하여 증기, 난방용 온수, 냉방용 냉수로 이용할 수 있어 총 효율이 70 ∼ 80%에 달하는 방식이다. 열병합 발전은 규모에 따라 목동열병합과 같은 쓰레기 소각로 이용형, 분당, 일산 등과 같이 지역난방과 연결할 수 있는 가스터빈, 증기터빈 조합형인 복합 열병합형의 대형열병합과 각 산업체 공장에서 전기 및 공장 Process 증기 생산을 주목적으로 하는 중형 열병합과, 조선호텔, 신라호텔, 상공회의소등과 같이 Hotel, 병원, 사무실 등에서 주로 이용하는 소형 열병합으로 분류할 수 있다.

1985년에서 1986년, 전남지방과 제주지방에서 채집한 바나나의 이병엽과 이병과에서 Fusarium moniliforme Sheld. 가 빈번하게 분리되었다. 분리된 F. moniliforme의 대형분생포자는 대부분 3개 내지 5개의 격막이 있고, 크기는 $20.0-50.0\times2.0-3.5{\mu}m$였으며, 소형분생포자의 크기는 $5.0-12.0\times1.5-2.5{\mu}m$였다. 병원성검정 결과, 이 균의 분리균주 중에는 병원성인 계통과 비병원성인 계통이 있음을 발견하였다. 접종시험에 의해 병원성인 계통의 균주들은 바나나의 잎에 잎끝마름병을 일으켰으며, 열매에는 열매끝썩음병과 수관썩음병을 일으켰다.

This study is to examine the infection management cognition and to practice of dental hygienists about their general characteristics, type of workplace. 354 dental hygienists in Daegu and Kyungbuk cities. The questionnaire survey was performed from April to May, 2015. These showed that factors of dental infection management according to workplace depended existence and nonexistence that chief of station and program of infection management, education of infection control(p<.001). Also cognition of dental infection control according to workplace drawed the protection individual(p<.05), asepsis procedure(p<.01), control of dental equipment(p<.001), control of infectious waste(p<.01) and laundry(p<.001), to practice of dental infection control according to workplace drawed the protection individual and asepsis procedure(p<.001), methods of disinfected and sterilized(p<.05), control of dental equipment and laundry(p<.001), control of infectious waste(p<.05). As above results, in order to minimize the infection prevention in the dental clinic, the regular infection control education for infection control of dental hygienists required, infection control guidelines place at the dental office.

Objectives The purpose of this case study was to report that cold hypersensitivity caused by hypothyroidism was alleviated by diagnosing and treating as Greater Yang Disease Reverting Yin Pattern. Methods The patient was administered Insamosuyu-tang and Sammisamyu-tang and treated with acupuncture. Global Assessment Scale (GAS) and Digital Infrared Thermal Imaging (DITI) was used to assess the improvements of symptoms. Results and Conclusions Cold hypersensitivity of hands and feet was improved to GAS 20, and hours of sleep were increased from one to six. On DITI, the increase of the temperature were 1-3 degree celsius on the chest and the abdomen, 0.2-1 degree on the forearms and the hands, 1-2 degree on the thighs, and 0.2-0.5 degree on the shins and the feet.

The pathogenicity of the fish nodavirus causing viral nervous necrosis (VNN) of sevenband grouper, Epinephelus septemfasciatus was examined in sevenband grouper and other marine fish by intramuscular injection. Sevenband groupers of 27~104 g in body weight were highly susceptible to the fish nodavirus, but yellowtail (537 g in body weight), red seabream (207 g), rock bream (43 g), flounder (41 g), tiger puffer (27 g) and rockfish (94 g) of the sizes used to this experiment were not. The pathogenicity of the viral agent to the sevenband grouper was high without regard to fish sizes at rearing water temperature over $20^{\circ}C$, but not at $15^{\circ}C$. Therefore, susceptibility of sevenband grouper to the viral agent causing VNN was thought to be water temperature-dependent rather than fish size (age-dependent). Compared to the infectivity of the viral agent to sevenband grouper with artificial infection methods, fish were successfully affected by intramuscular, intraperitoneal, oral, dipping and cohabitation administrations although there were slight differences in mortalities among infection methods. And survival sevenband grouper after infection with the fish nodavirus was resistant to the reinfection for a long time.

The first case of Middle East Respiratory Syndrome (MERS) was reported in Korea in 2015, after a Korean man from Bahrain tested positive for the infection. After first eruption, there were numbers of secondary infectees and whole country were frightened. At the time, isolated ambulances were available but few, and there was no specific way to prevent contamination during transfer. Therefore, Seoul National University Hospital and the University of Seoul developed isolation units and air filters. Four years after the MERS outbreak, this study measured the differential pressure inside and outside the small isolation units based on the differential pressure and air flow derived from simulation and testing, and proposed minimum values for virus leakage and internal sealing. A performance evaluation and testing method for the transfer equipment is proposed. The critical function of the small isolated transport equipment was defined and selected as an evaluation item; performance evaluation was carried out by simulating a real-world case. The results provide the proper pressure configuration of positive and negative pressure inside the segregation feeder; the clear criteria for the HEPA filter; and the performance criteria for the segregation feeder and air purifier.
