Background: Solar urticaria (SU) is an uncommon type of photodermatoses characterized by erythematous wheal with pruritus after sunlight exposure, which shows a female predominance. Only a few studies to analyze the clinical features of SU were reported in Asia. Objectives: We aimed to analyze the clinical and photobiological characteristics of SU in Korea. Methods: We retrospectively investigated the medical records of patients with SU who visited the department of dermatology, Konkuk university medical center from January 2005 to January 2020. Results: Of a total of 44 patients, 36 (81.8%) were male and 8 (18.2%) were female. The mean age at onset was 17.6 years (range, 5-47) and the mean threshold time was 19.7 minutes. Among 32 patients who underwent phototesting, the action spectrum most commonly implicated was ultraviolet (UV) A only in 12 (37.5%), and then visible light (415nm) only was responsible for SU in 8 (25.0%). Three patients (9.4%) were induced by both UVA and visible light (415nm). Even 4 patients (12.5%) were triggered by only natural sunlight. Serum immunoglobulin E levels were measured in 33 patients, and 17 (51.5%) showed values higher than normal. The treatment most widely used were oral antihistamine (43.2%), followed by phototherapy (13.6%). Conclusion: SU is a rare photodermatosis in Korea, which shows a male preponderance. In this study, UVA and visible light (415nm) were predominant action spectrum of SU.

In Vitro Antiviral Activity of Ribavirin Against Severe Fever with Thrombocytopenia Syndrome Virus Myung Jin LEE1, Kye-Hyung KIM1, Jongyoun YI2, SuJin CHOI1, Chung-Jong KIM1, Nak- Hyun KIM1, Kyoung-Ho SONG1, Pyoeng Gyun CHOI1, Ji-Hwan BANG1, Wan Beom PARK1, Eu Suk KIM1, Sang-Won PARK1, Hong Bin KIM1, Nam Joong KIM1, Myoung- Don OH1 Seoul National University College of Medicine, Korea1, Pusan National University School of Medicine, Korea2 Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel Bunyavirus, severe fever with thrombocytopenia syndrome virus (SFTSV). No effective antiviral therapy is proven yet, but clinical use of ribavirin (RBV) has been tried. We investigated the antiviral effect of RBV against SFTSV in vitro. Methods: To test for cytotoxicity of RBV, Vero cells were treated with different concentrations of RBV (3.90 to 500 μg/mL, two-fold dilution) and analyzed by cell viability MTS assay 48h post-infection. To determine antiviral activity of RBV against SFTSV, Vero cells were infected with SFTSV strain Gangwon/Korea/2012 at 100 TCID50 (50% tissue culture infective dose) per well in a 96-well plate, and RBV was added at the concentrations showing no or minimal cytotoxicity. Viral RNAs were extracted from the culture supernatants and quantifi ed using one-step real-time reverse transcription- PCR to amplify the partial large segment of SFTSV. Statistical analysis was done by one-way ANOVA with Tukey`s post hoc test. Results: Cytotoxicity due to RBV was not observed at RBV concentration =31.3 μg/ mL. Viral RNAs at 24h post-RBV treatment were reduced with increasing RBV concentrations (1-32 μg/mL), compared with those of mock-treated cells (P <0.01, Figure). Half maximal inhibitory concentration (IC50) of RBV was 3.69 μg/mL at 24h post-RBV treatment. Conclusions: Our study shows that RBV has antiviral effect against SFTSV in a dose-dependent manner. Further studies are required to evaluate the effi cacy of RBV in SFTS.

A multiplex polymerase chain reaction (PCR) method was developed to simultaneously detect 3 events of genetically modified (GM) maize. The event-specific primers were used to discriminate the following 3 events of GM maize (DAS-59122-7, TC6275, and MIR604) using multiplex PCR method. The zein gene was used as an endogenous maize reference gene in the multiplex PCR detection. The primer pair Zein-F/R producing a 99 bp amplicon was used to amplify the zein gene. The primer JI-Das-F1/R1 for DAS-59122-7, JI-TC6275-F3/R3 for TC6275, and JI-MIR F1/R1 for MIR604 yielded an amplicon of 130, 162, and 197 bp, respectively. The detection limit of multiplex PCR was 1% for DAS-59122-7, TC6275, and MIR604 for one reaction.

As medical technology progresses rapidly, there is a rise in the average age along with the Korean dietary lifestyle becoming more westernized, which leads to an increase in the number of vascular disease patients in Korea. Thus, we need to manage the medical information of a disease systematically in order to diagnose and treat constructively. However, since there has been no standardized method of man agement to date, a great deal of information could not be properly utilized nor studied. Therefore, the departments of Cardiology, Radiology and Neurology of Samsung Seoul Hospital recently got together to develop an information management system called the Vascular Data System. This program was developed to be run on win98 O/S, upper Pentium Ⅲ, and upper 128 MB Memory, and its source code is Dephi 4.0. It was configured for the user to set the configurations as well as do a variety of search and analysis. If this program were to be updated continuously, it may be used extensively as well as in various parts of clinical research activities.

This letter proposes a handover ranging power adjustment scheme to improve handover performance. Incorrect ranging power can degrade handover performance due to the increased handover latency; therefore, the proposed scheme exploits the uplink channel information to adjust the uplink handover ranging power. Simulation results demonstrate that the proposed scheme reduces call outage probability by 33% compared to that of the conventional scheme. It also improves the number of users who satisfy the system requirements for handover interruption time.

배경 및 목적: 본 연구는 전자구개도를 사용하여 한국어의 치경마찰음인 /ㅅ/와 /ㅆ/를 조음운동적 측면에서 비교 분석해보고, 치경마찰음 조음 시 나타나는 혀-구개 접촉에 관한 정보를 제공하기 위한 목적으로 시행되었다. 방법: 한국어가 모국어이며 발음에 문제가 없는 정상 성인 5명이 전자구개도를 착용하여 치경마찰음을 분절음 차원에서뿐 아니라 단어 내 위치 및 모음문맥을 달리하여 녹음한 후 팰라토그램을 분석하였다. 결과: 그 결과, /ㅅ/와 /ㅆ/는 협착의 너비와 혀-구개 최대접촉구간에서 유의한 차이를 보였다. /ㅆ/에서 협착의 너비가 더 좁고 전체 혀-구개 접촉구간은 더 넓게 나타났다. 단어 내 위치에 따른 차이는 유의하지 않았지만, 고모음인 /ㅣ/ 문맥에서는 저모음인 /ㅏ/에 비해 협착의 위치가 후방화되었으며, 지속시간도 가장 긴 것으로 나타났다. 또한 혀-구개 접촉 구간도 가장 넓게 나타났다. 논의 및 결론: 본 연구는 전자구개도를 사용하여 한국어 치경마찰음의 혀와 구개 접촉에 관한 정보를 제공했다는 점에서 그 의의를 갖는다. 또한 본 연구의 결과는 한국형 전자구개도의 개발의 기초자료로써 그 의미가 있다. Objectives: The present study is aimed an electropalatographic investigation of Korean fricatives /s/ and /s*/. All data from this study is based on the production of 5- adult speakers who speak Korean as their first language. Methods: Electropalatography (EPG) is an instrumental technique for showing tongue and palate contact during speech. The participants recorded /s/ and /s*/ in CV (/si/, /sɑ/, /su/, /s*i/, /s*ɑ/, /s*u/) and VCV (/ɑsi/, /ɑsɑ/, /ɑsu/, /ɑs*i/, /ɑs*ɑ/, /ɑs*u/) context using EPG and then, four variables were analyzed: row of medial groove (RMG), medial groove width (MGW), medial groove length (MGL), and maximum contact frame (MCF). Results: There was significantly greater medial groove width and maximum contact frame for / s*/ compared to /s/. The difference between /si/ and /sɑ/ was also found in the row of medial groove, medial groove width and maximum contact frame. /si/ was produced further back, and had a longer medial groove length. Also, it showed more total tongue-palate contact than /sa/. Conclusion: A various range of palatal contact patterns were found between typical adults for perceptually normal /s/ and /s*/. The results provided the information about tongue–palate pattern of Korean fricatives /s/ and /s*/. These findings would be utilized to build the basic data and useful information for Korean EPG system.

Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 1-15, 2004. The purpose of this study was to investigate the kinematic variables of the upper part of the body for 8 elderly men during walking. For this study, kinematic data were collected using a six-camera (240Hz) Qualisys ProReflex system. The room coordinate system was right-handed and fixed in space, with righted orthogonal segment coordinate systems defined for the head, trunk, and pelvis. Based on a rigid body model, reflective marker triads were attached on the 3 segments. Three-dimensional Cartesian coordinates for each marker were determined at the time of recording using a nonlinear transformation(NLT) technique with ProReflex software (Qualisys, Inc.). Coordinate data were low-pass filtered using a fourth-order Butterworth with cutoff frequency of 6Hz. Three-dimensional angles of the head, trunk, and pelvis segment were determined using a Cardan method. On the basis of each segment angle, angle-angle plot used to estimated the movement coordinations between segments. The conclusions were as follows; (1) During the support phase of walking, the elderly people generally kept their head the flexional and abductional posture. Particularly, the elderly displayed little internal/external rotation. (2) The elderly people showed extensional and external rotation postures in the trunk movement. Particularly, It showed the change from adduction into abduction at the heel contact event of the stance phase. (3) The elderly people showed almost same pelvis movement from the flexion into extension, from the abduction into adduction, and from internal rotation into external rotation at the mid stance and toe off of the stance phase.
