Concealed congenital long QT syndrome during velopharyngeal dysfunction correction: a case report
Jeon, Soeun,Lee, Hyeon-Jeong,Jung, Young-hoon,Do, Wangseok,Cho, Ah-Reum,Baik, Jiseok,Lee, Do-Won,Kim, Eun-Jung,Kim, Eunsoo,Hong, Jeong-Min The Korean Dental Society of Anesthsiology 2020 Journal of Dental Anesthesia and Pain Medicine Vol.20 No.3
The congenital long QT syndrome (LQTS) is an inherited cardiac disorder characterized by increased QT intervals and a tendency to experience ventricular tachycardia, which can cause fainting, heart failure, or sudden death. A 4-year-old female patient undergoing velopharyngeal correction surgery under general anesthesia suddenly developed Torsades de pointes. Although the patient spontaneously resolved to sinus rhythm without treatment, subsequent QT prolongation persisted. Here, we report a case of concealed LQTS with a literature review.
Nonresponse in Repeated Surveys

Under repeated surveys, missing values often appear for various reasons and are replaced by new samples. It is investigated that the existing estimator in repeated survey by Jessen (1942), which has been originally developed for the new samples of fixed size, can be used in such situation where the size of new samples is random. It is shown that the proposed estimator has smaller variance than the sample mean.

Jung-Ah Seo,Min Young Jeon,Hyeon Lee Lee,Sun-A Cho,Susun An,Bae-Hwan Kim 한국실험동물학회 2021 한국실험동물학회 학술발표대회 논문집 Vol.2021 No.7
Some chemicals can bind to skin proteins and induce sensitization. Direct peptide reactivity assay (DPRA) listed in the OECD guideline is an alternative method to evaluate the skin sensitization, by assessing a substance"s reaction to peptides. Newly modified spectrophotometric method for skin sensitization evaluation (spectro-DPRA) in Korea can improve some defect of DPRA. Pre-validation studies for spectro-DPRA were conducted at three institutions (AP, KTR, and KCL) to exam the transferability and proficiency, within and between laboratory reproducibility, and predictive ability based on GLP principle. All organizations confirmed more than 90% of agreements for the proficiency evaluation using ten chemical substances. Within the laboratory reproducibility evaluation, the agreement rate between the three tests performed by each institution was confirmed as 90% for AP, 100% for KTR, and 100% for KCL, and 90% agreement was approved when comparing with LLNA data. In evaluating reproducibility between the three laboratories, the agreement was 86.7%, showing a high value, and the degree of agreement with the LLNA data result was confirmed as 86.7% for AP, 100% for KTR, and 86.7% for KCL. Additional 54 substances were used to verify the prediction rate. As a result, 29 out of 33 sensitizers were identified as sensitizers, and 19 out of 21 non-sensitizers were identified as non-sensitizers, confirming a sensitivity of 87.8%, a specificity of 90.4%, and an accuracy of 88.8%. According to the results, the spectro-DPRA skin sensitization test presented adequate predictive capacity compared with the existing DPRA or ADRA while representing a method to save time and cost.

7년 전부터 당뇨병으로 인슐린 치료 중이던 24세 남자 환자가 내원일 오전에 발생한 복부 불편감을 주소로 내원하였고, 복통에 대한 검사 중 복부 전산화 단층촬영 결과 배측췌장 발육 부전증과 좌측 신장 및 12번 흉추의 좌측 추궁근 결손이 발견되었다. 자기공명 담췌관조영술에서 주 췌관은 정상적이었으며 산토리니관(Santorini-duct) 및 체부와 미부의 췌관은 관찰되지 않았다. 저자는 복부 전산화 단층촬영과 자기공명 담췌관조영술을 통해 선천적 배측 췌장 발육 부전증과 동반된 신장 및 척추의 기형을 진단하였고, 이에 다발성 선천성 기형과 당뇨병이 동반된 배측 췌장 발육 부전증 1예를 보고하는 바이다. Agenesis of the dorsal pancreas is a rare congenital anomaly that arises from the failure of the dorsal pancreatic bud of endodermal cells to form the body and tail of the pancreas and can manifest as diabetes. A 24-year-old man, who had been treated with insulin for 7 years, presented with epigastric pain, vomiting, and watery diarrhea. Abdominal computed tomography showed only the head of the pancreas without visualization of the pancreatic body and tail. Left renal agenesis and absence of the left vertebral pedicle in T12 were also observed. The duct of Santorini and the duct in the body and tail were not visible in magnetic resonance cholangiopancreatography. The associated anomalies reported here are very rare globally. We report a case of complete agenesis of the dorsal pancreas with multiple congenital abnormalities and diabetes mellitus.

The purpose of this study is to find out the importance of marketing that stimulates consumers' five senses and to further study the factors that consumers choose salons to help them find a developmental direction to enhance customer satisfaction. As for the subject of this study, a total of 350 questionnaires were distributed, and 323 of them were retrieved and statistical data was obtained with 312 valid questionnaires. SPSS 22.0 was used to analyze the collected data. Analytical analysis was carried out on the data in the form of frequency analysis, factor analysis, reliability analysis, and regression analysis. As a result, first, The tactile, palate, auditory, and visual areas, excluding olfactory areas, which are sub-factors of sensory marketing, were found to partially affect saloon selectivity (brand, internal and external attributes). Second, Sensory marketing also partially affected customer satisfaction, recommendation, and revisitability, of which auditory areas affected all factors. Through this study, the importance of sensory marketing and marketing strategy that increases positive customer response will be helpful.

이 논문에서는 LMS가 무엇이며, ‘소통 교육’의 도구로서 LMS의 필요성과 활용성에 대해 확인하고자 한다. 이를 위해 국제적 소통의 기준이 무엇이며, 소통의 기능으로서의 LMS의 역할 및 기능에 대해 탐색하였고, 고려대학교의 기존 LMS와 세계 LMS 시장의 양 축인 Blackboard 및 Moodle의 기능을 비교하여 소통의 도구로써 활용할 수 있는 기능을 확인하였다. 이를 기반으로 공대 학습자를 대상으로 새로운 LMS에 대한 의견을 조사하여 앞으로의 활용 및 지원 방안에 대한 전략을 도출하였다. This paper discusses what the learning management system(LMS) is and the needs & usability of the LMS as a tool for ‘communication education’. In order for the detailed discussion, we explores the standards of the global communication, and roles & functions of the LMS as a function of communication. The functions are compared for the cases of the pre-existing LMS at Korea University, the Blackboard and the Moodle (two world-leading learning management systems) by assessing and comparing their availability as a tool for communication. A survey has been conducted to gather the comments on the LMS designed for the learners at engineering department. The strategies for the future utilization and the support of the LMS are suggested based on the survey.
