Traumatic dislocation of the peroneal tendon is an infrequent injury. This injury is caused by forceful dorsiflexion of the foot accompanied by a powerful contraction of the peroneal muscles. This mechanism of injury tears the superior peroneal retinaculum and allows the tendons to snap anteriorly. We experienced a case of chronic recurrent dislocation of the peroneal tendon, which was treated by bone block surgery using autograft of lateral fibula and reattachment of the superior peroneal retinaculum. The clinical result was satisfactory.

Fluorine-doped tin oxide (FTO) nanoparticles have been successfully synthesized using ultrasonic spray pyrolysis. The morphologies, crystal structures, chemical bonding states, and electrochemical properties of the nanoparticles are investigated. The FTO nanoparticles show uniform morphology and size distribution in the range of 6-10 nm. The FTO nanoparticles exhibit excellent electrochemical performance with high discharge specific capacity and good cycling stability ($620mAhg^{-1}$ capacity retention up to 50 cycles), as well as excellent high-rate performance ($250mAhg^{-1}$ at $700mAg^{-1}$) compared to that of commercial $SnO_2$. The improved electrochemical performance can be explained by two main effects. First, the excellent cycling stability with high discharge capacity is attributed to the nano-sized FTO particles, which are related to the increased electrochemical active area between the electrode and electrolyte. Second, the superb high-rate performance and the excellent cycling stability are ascribed to the increased electrical conductivity, which results from the introduction of fluorine doping in $SnO_2$. This noble electrode structure can provide powerful potential anode materials for high-performance lithiumion batteries.

This study was aimed to understand the recognition of care robots which would enhance the medical quality of life under the 4^th industrial revolution in the university students majoring in health and engineering who would lead the development of the future medical industry and to find out the differences of their digital literacy and empathic ability. This was a descriptive correlation study to analyze the recognition of university students on care robots, their digital literacy and empathic ability. Both students majoring in health and engineering recognized the needs of care robots, while their education experiences were not sufficient. Moreover, statistically fewer university students majoring in health heard about care robots than those in engineering, and their need of taking classes was lower, too. No statistically significant differences were found in digital literacy and empathic ability between the two majors, while significant difference was found in the relationship bundling capability out of behavioral empathy, a sub-domain of empathic ability. The study results are anticipated to suggest the future educational direction in the medical field according to the 4^th industrial revolution and to be the fundamental data for understanding and preparation of the students depending on the majors. 본 연구에서는 4차 산업형명의 의료 삶의 질을 향상시켜줄 케어로봇에 대하여 미래 의료 산업 발전을 주도할 보건전공 대학생과 공학전공 대학생의 케어로봇에 대한 인식을 확인하고, 이들의 디지털 리터러시 및 공감능력의 차이를 확인하고자 하였다. 본 연구는 대학생의 케어로봇에 대한 인식과 디지털 리터러시 및 공감능력에 대해 분석하기 위한 서술적 상관관계 연구이다. 보건계열 대학생과 공학계열 대학생은 케어로봇에 대한 필요성을 인식하고 있었으나, 교육 경험이 두 군 모두 미흡하였다. 더욱이 보건계열 대학생의 경우 케어로봇에 대해 들어본 경험이 공학계열 학생보다 통계적으로 낮았으며, 수강 요구도 또한 낮았다. 보건계열 대학생과 공학계열 대학생의 디지털 리터러시는 통계적으로 유의한 차이가 없었고, 공감능력 통계적으로 유의한 차이가 없었지만 하위영역인 행동적 공감에서 관계형성능력은 통계적으로 유의한 차이가 있었다. 본 연구를 통하여 추후 4차 산업에 따른 의료 분야의 교육의 다학제간의 방향성을 제시하고 전공에 따른 학습자들을 위한 이해와 준비의 기초자료가 될 수 있기를 기대한다.

Single cell gel electrophoresis (SCGE) assay, also called comet assay, is a rapid and sensitive method to detect DNA damage in single cell level. To evaluate the DNA damage of lymphocytes of pesticides sprayers, SCGE assay was carried out for 50 pesticides sprayers and 58 control subjects. They were interviewed with structured questionnaire to get the information about the kinds and amount of pesticide. Insecticides and fungicides were predominant among pesticides. Major components of pesticides were organophosphorus, organosulfate, cartap, carbamates, and triazole. Sprayed pesticides were classified into two groups. Group I included organophosphorus, organoarsenic, organotin, tetrazine, triazole and gramoxone, which were known to cause DNA damages. Group II pesticide were carbamates, surfactants, organosulfates, etc., which were not found as DNA damaging agents in scientific documents. Olive tail moments of 100 lymphocytes were measured by<br/> KOMET 3.1 program for each person. The means of tail moments were compared between farmers exposed to pesticides and control subjects. Farmers showed higher tail moments than control subjects (2.07±1.40 vs 1.53±0.77, p<0.05). The means of tail moments also were compared among group I sprayers (n=36), group II sprayers (n=24) and, control subjects, and the means of tail moments were 3.45±3.20, 2.66±2.20 and 1.53±0.77 respectively. The difference between means of group I sprayers and controls was statistically significant (p<0.05). In conclusion, this study showed higher DNA damage in farmers exposed to pesticides than control subjects, and<br/> comet assay could be useful as a biological monitoring method of genotoxic pesticides for farmers.
