The recent increase in severe fever with thrombocytopenia syndrome (SFTS) cases has led to the development of the SFTS-QS kit (MiCoBioMed, Seongnam, Korea) for detecting the SFTS virus (SFTSV, now renamed Huaiyangshan banyangvirus). SFTS-QS is a qualitative real-time reverse transcription PCR assay based on lab-on-a- chip technology. We evaluated the performance of the SFTS-QS kit and compared it with that of the PowerChek SFTSV Real-time PCR kit (PowerChek; Kogene Biotech, Seoul, Korea). A total of 117 serum samples were simultaneously assayed using the SFTS-QS and PowerChek kits. Sanger sequencing targeting the S and M segments of SFTSV was performed as the reference method. The total turnaround time of the two kits was compared. The SFTS-QS results agreed with those of PowerChek with a kappa value of 0.92. The diagnostic sensitivity and specificity of the SFTS-QS kit were both 100% (14/14 and 103/103, respectively), whereas those of the PowerChek kit were 100% (14/14) and 98.1% (101/103), respectively. The results of SFTS-QS and PowerChek were comparable; however, the SFTS-QS kit required a shorter total turnaround time. The SFTS-QS kit produced accurate and fast results and thus could serve as a useful tool

The purpose of this research is to study the performance assessment made by high school home economics teachers : their awareness and attitudes toward the assessment correlate with the qualitative output of the executions of it. as well s to determine how their awareness and attitudes toward the assesment correlate with the qualitative output of the executions of their performance assessments. The research has yielded the following results : 1. The attitudinal score shows above average of 58.7/90. By the sub-factors. awareness of the characteristics of performance assessment is 20.6/30 : the favorable attitudinal score is at 20.0/30. the behavioral attention at 9.5/15. and the effects of performance assessment on the teachers and the classes at 8.6/15. 2. In a single semester. the highest frequency of executing performance assessment is between 1 to 2 times (58.7%). and practical skill test is proven to be the most frequently used category at 79.9%. 3. The correlation between the overall attitude on performance assessment and the quality of actual performance assessment executed is high. indicating superior quality of performance assessment. which is directly proportionate to the enhanced attitude of teachers on performance assessment.

The purpose of this study was to identify the health-related quality of life(HRQoL) according to oral health and visual/hearing functional status of elderly women. Participants of the study included 247 elderly women the age of 65 who were using senior centers. Data was analyzed by using SPSS/Win 25.0. The means of HRQoL using EuroQol-5dimensions(EQ-5D) and EuroQol-visual analogue scale(EQ-VAS) of participants were 0.79(±.12) and 56.88(±13.97), respectively. There were significant positive correlations between EQ-5Dindex and EQ-VAS. The non dentures-wearing group had significantly higher scores in EQ-5Dindex and EQ-VAS than the dentures-wearing group. The factors affecting the EQ-5Dindex of participants are age, spouse, medical security, educational level, number of teeth, and perceived oral health status(R2=.428). The age, medical security and dentures-wearing are factors affecting the EQVAS( R2=.332). These results suggest that it is necessary to improve the overall quality of life by developing and applying the healthcare program according to oral health status of the elderly in community.

조선조대 호실전적의 허실과 삼각함수표

유인영 한국수학사학회 2002 Journal for history of mathematics Vol.15 No.3

The area between the arc and chord of a circle is called Hosichun whose figure looks like a bow and an arrow, and had been evaluated by the two formulas $\textit{H}_{n1}$=a(a+y)/2 and $\textit{H}_{n2}$=3ay/4, where $\alpha$ is the length of the arrow and y the chord of the circle. By the inspection of the area of the Hosichun, some errors of the numeration table in Thurmans S. Peterson's CALCULUS were found easily, that is, the area of the Hosichun is smaller than its subarea in the same Hosichun and perhaps has been to be the worldwide and centurial invalid standard. From now on, the chain proofreadings of the errors will be necessary in our mathematical world. This paper is intended to introduce some such problems related to a circle and another Pythagorean Theorem which is the ratio of the side and diagonal of five and seven In a square.

To find one side of the square equal to the area of a circle is an unsolved problem. Likewise, to think one side of the cube equal to the volume of a sphere is another unsolved problem. There are four methods to find the area of the circle and the volume of the sphere. This paper aims to weigh each method against the other in finding the answers of the problems in the Chosun Dynasty and investigate their own characters.

메카트로닉스 기능훈련반 학생들이 범하는 오류에 대한 탐색

유인영,최준섭 한국기술교육학회 2013 한국기술교육학회지 Vol.13 No.3

The purpose of this study was to check the errors and to analyze the causal relationships in students of mechatronics skill training class. In order to achieve the objective of this study, the qualitative study through interviews and observations were carried out with 2 students of second-year grade in P technical High School. The result of this study were as follows;First, the types of errors for students to make were consisted of teamwork and communication errors, PLC and program understanding errors, preparation errors, problems interpretation errors, and psychological condition errors. Second, the reasons were as follows;Teamwork and communication errors were caused by failing to share the work through the communication with each other. PLC and program understanding errors were made by a lack of information and understanding about the PLC and program. Preparation errors were caused by a lack of preparation and checking operation for a list of materials before work. Problems interpretation errors were caused by confusion the order process as the problem was presented in narrative. And finally, psychological condition errors were found by body condition or psychological condition of the students on working day. 이 연구는 메카트로닉스 기능훈련반 학생들이 문제해결과정에서 범하는 오류를 확인하고, 인과관계를 분석하기 위해 이루어졌다. 이를 위해 P공업고등학교 메카트로닉스 기능훈련반 2학년 학생 2명을 대상으로 면담과 관찰을 통한 질적연구방법을 실시하였고, 연구결과는 다음과 같다. 첫째, 학생들이 문제해결과정에서 범하는 오류 유형으로 팀워크 및 의사소통의 오류, PLC 및 프로그램 이해의 오류, 사전준비 오류, 문제 해석의 오류, 심리 상태의 오류를 확인할 수 있었다. 둘째, 오류의 발생 원인을 살펴보면 먼저, 팀워크 및 의사소통의 오류는 서로간의 의사소통을 통해 작업내용을 공유하지 못해서 발생된다. PLC 및 프로그램 이해의 오류는 PLC 및 프로그램에 대한 정보와 이해가 부족하여 발생된다. 사전준비 오류는 학생들이 작업 전에 재료 목록에 대한 작동여부확인 및 준비가 부족하여 발생된다. 문제 해석의 오류는 문제가 서술형으로 제시되면서 공정 순서를 착각하는 경우에 발생된다. 그리고 마지막으로 심리 상태의 오류는 작업 당일 학생의 몸 상태나 심리 상태에 따라 발생된다.

Linezolid Resistance in Methicillin-Resistant Staphylococcus aureus in Korea: High Rate of False Resistance to Linezolid by the VITEK 2 System

As various linezolid resistance mechanisms have been identified in methicillin-resistant Staphylococcus aureus (MRSA), we investigated the molecular characteristics of MRSA with elevated linezolid minimum inhibitory concentrations (MICs), using the VITEK 2 system (bioMérieux, Marcy-l’Étoile, France). Twenty-seven MRSA isolates from 14 patients exhibiting linezolid MICs ≥8 μg/mL were examined by broth microdilution (BMD) test as well as by sequencing for mutations in the 23S rRNA gene or ribosomal proteins (L3, L4, and L22) and the presence of the optrA, cfr, and cfr(B) genes. Of the 27 isolates, four (14.8%) from one patient were confirmed as linezolid resistant by BMD and harbored a 23S rRNA T2500A mutation. The remaining 23 were confirmed as linezolid susceptible, indicating that the linezolid-resistant results were major errors generated by VITEK 2. The most commonly detected mutation (19/27, 70.4%), L3 Gly152Asp, was detected in only linezolid-susceptible isolates. No isolates contained optrA, cfr, or cfr(B) or any L4 or L22 protein alterations. Our results show that the 23S rRNA T2500A mutation was mainly associated with linezolid resistance, while the L3 Gly152Asp mutation was not related to linezolid resistance. A confirmatory test is recommended for VITEK 2 linezolid-resistant results owing to the high probability of false resistant results.
