Trichloroethylene (TCE) is an unsaturated chlorinated hydrocarbon in the form of a colorless, volatile liquid, which is used as an industrial organic solvent for spot removal and for metal degreasing. In general, the primary complications of TCE poisoning result from involvement of the central nervous and respiratory systems, including aspiration pneumonia. A case is reported of a 54-year-old man who presented in a comatose state after accidental ingestion of 100 ml of TCE, and who recovered after conservative treatment and mechanical ventilation. We discuss this case and present a literature review.

Objectives : The objective of this study is to study the effects of Euonymi Lignum Suberatatum pharmacopuncture solution on NO and IL-6 production in macrophage. Methods : At first, the RAW 264.7 macrophage was subclutured. In order to evaluate cytotoxicity, MTT assay performed. Then, the cell was induced by LPS, INF-$\gamma$ and Experimental groups were divided into five(Normal, Control, Euonymi Lignum Suberatatum 100, 200, $300{\mu}g/m{\ell}$). Then Euonymi Lignum Suberatatum pharmacopuncture solution was put into cell. We measured IL-6, iNOS, NO. Results : The cytotoxic effect of Euonymi Lignum Suberatatum pharmacopuncture solution in RAW 264.7 macrophage was not appeared. $300{\mu}g/m\ell$ Euonymi Lignum Suberatatum pharmacopuncture solution inhibited IL-6 production in LPS, INF-$\gamma$-stimulated RAW 264.7 macrophages significantly. Euonymi Lignum Suberatatum pharmacopuncture solution inhibited iNOS revelation in LPS, INF-$\gamma$-stimulated RAW 264.7 macrophages. All group of Euonymi Lignum Suberatatum pharmacopuncture solution inhibited NO production in LPS, INF-$\gamma$-stimulated RAW 264.7 macrophages significantly. Conclusions : Our study demonstrated that Euonymi Lignum Suberatatum pharmacopuncture solution had an inhibition effect on NO production, iNOS revelation, IL-6 production. So Euonymi Lignum Suberatatum pharmaco puncture solution may have an Anti-inflammation effect.

Objectives : This is a clinical report about the Conversion Disorder, Wei symptom patient. Methods : The patient was treated by acupuncture, herb medication, moxibustion, physical therapy and bio feedback. The improvement of the patient was judged by lower limb elevation test and gait condition test. Results : During the 1st duration, lower limb elevation angle of the patient had improved. And the patient's gait condition had improved. But he received stress so that same symptom appeared again. Then, after the second treatment, He could walk alone again. Conclusions : Oriental medicine treatment including Acupuncture, Herb medication was very effctive to improve the Conversion disorder patient's symptoms. It is necessary to have more observation and many cases of patients with Conversion disorder.

Suicide Attempt by Inhalation of Argon Gas

전재천,최우익,정수원,이주환 계명대학교 의과대학 2021 계명의대학술지 Vol.40 No.1

Suicide attempts using asphyxiants have been increasing compared to the past. Argon is an inert gases which is harmless to the human body, but when inhaled, can causes suffocation due to lack of oxygen. A 24-year-old man was admitted to the emergency department after an attempted suicide using argon gas. At the time of arrival, his mental status was drowsy and hematologic data indicated lactic acidosis. Consciousness was recovered after 3 hours and he was discharged without complications. He stated that he had discovered about argon gas through a suicide website and proceeded to make his purchase online. Nowadays, such websites with information on suicides are exposed to the general public without discretion and has become a major social issue. Therefore, although current suicide rates using argon gas are low in Korea, it is a suicide method to take note of in the future.

메타버스 환경의 융합(STEAM) 교육 프로그램 개발과 적용을 통한 학습자 태도 및 만족도 분석

전재천,장준혁,정순기 한국정보교육학회 2022 정보교육학회논문지 Vol.26 No.3

Recently, with interest in metaverse, attempts are being made to utlize the metaverse platform in various forms. In this paper, we focused on the educational application potental of metaverse, and developed and applied a metaverse STEAM program to provide an effective learning experience to learners in non-face-to-face educational situations. The developed program utilizes Minecraft and ZEPETO, familiar to students, as metaverse learning platforms, and consists of a total of 16 lessons of 5 modules in the form of modules so that altematve classes can take place in the educational field. Through this, the learner's change in STEAM attitude and learning sat­isfaction were measured, and through the developed STEAM program, the learner's interest, consideraton, com-munication, usefulness, self-concept, self-efficacy, and career choice areas significantly increased. In additon, pos­itive results were confirmed in all areas of the learner satisfaction test related to satsfartion, interest, and overall class. In the future, considering the characteristcs of the metaverse, it is necessary to break free from the con­straints of time and space to communicate anew, and various learner-centered educatonal approaches based on a high degree of freedom and immersion should be implemented. 최근 메타버스(Metaverse)에 대한 관심과 함께 메타버스 플랫폼을 다양한 형태로 활용하려는 시도가 이루어지고 있다. 본 논문에서는 메타버스가 가지고 있는 교육적 활용 가능성에 주목하고, 비대면 교육 상황에서 학습자에게 효과적인 학습 경험을 제공하기 위한 메타버스 환경의 융합(STEAM) 프로그램을 개발 및 적용하였다. 개발한 프로그램은 학생들에게 친숙한 마인크래프트와 제페토를 메타버스 학습 플랫폼으로 활용하였고, 모듈 형태의 5가지 주제를 총 16차시로 구성하여 교육현장에서 차시 대체형 수업이 이루어질 수 있도록 하였다. 이를 통해 학습자의 STEAM 태도의 변화 및 학습 만족도를 측정했으며, 개발한 융합 프로그램을 통해 학습자의 흥미, 배려, 소통, 유용성, 자아개념, 자아효능감, 진로선택 영역이 유의미하게 상승한 것으로 나타났다. 또한 만족도, 흥미, 수업 전반과 관련된 학습자 만족도 검사 전 영역에서도 긍정적인 결과가 확인되었다. 향후 메타버스의 특성을 고려하여 시공간의 제약을 탈피하여 새롭게 소통하고, 높은 자유도와 몰입도를 바탕으로 하는 학습자 중심의 다양한 교육적 접근이 이루어져야 할 것이다.

Purpose: There have been local wound complications in patients who have received first aid after venomous snake bites. Yet first aid in relation to local wound complications has not been well studied. Methods: We conducted a 5-year retrospective study of 111 snake bite patients who visited the emergency departments of several medical centers between January 2004 and December 2008. We categorized the patients into those who had complications with inadequate first aid, those who had complications without first aid those who had complications with adequate first aid. We compared the genera characteristics and the laboratory and clinical findings of the three groups. Results: The ale o female ratio was 1.36. The most common bite site was fingers. The most common systemic symptom was dizziness (6.3%) and the most common complication was rhabdomyolysis (23.4%). The inadequate first aids group had more local complications (cellulitis, skin necrosis) than did the group with adequate first aid or the group with no first aids. Conclusion: Inadequate first aid after snake bite leads to local complications, so we must be careful to administer first aid after snake bite and evaluate this first aid in elation to local complications.

로봇 프로그래밍 교육에서 웹2.0 도구의 활용 모형

전재천,유인환 한국정보교육학회 2014 정보교육학회논문지 Vol.18 No.2

인터넷 서비스는 개방, 공유, 참여의 성격을 표방하며 인터넷 환경에 사용자가 적극적으로 참여하는 형태로 변화하고 있다. 본 연구에서는 이러한 흐름에 부응하여 기존의 로봇 프로그래밍 모형을 바탕으로 웹2.0 환경에 부합하는 긍정적인 상호작용을 촉진하기 위한 교육모형을 제안하였다. 우선 웹2.0의 환경의 특성과 이를 구현할 수 있는 교육적 도구에 대해 고찰하였고, 지금까지 연구되어 온 로봇 교육 및 로봇 프로그래밍 교육과 학습모형에 대해 살펴보고 시사점을 도출하였다. 또한 협력적 상호작용을 촉진할 수 있도록 웹2.0 도구(싸이월드, prezi, mindmeister)를 활용한 교육모형을 구안하고 이를 학습자에게 적용해보았다. 본 연구 결과 웹2.0 기반의 도구를 활용한 로봇 프로그래밍 교육이 유의미하다는 결과를 얻을 수 있었으며, 참여한 학습자 대부분은 웹2.0의 도구를 활용하는 것이 로봇 프로그래밍 과정 전반에 도움이 되었다고 평가하였다. Modern internet service is characterized as opening, sharing and participation based on Web2.0 so that users might actively participate in the internet environment. In this study, we suggested an instructional model based on precedent model of robot programming to promote positive interaction in Web2.0 environment. Frist, we figured out implications of precedent research through review the environmental features of Web2.0 and educational tools, robot programming learning model. Also, we suggest an instructional model using Web2.0 tools(cyworld, prezi, Mindmeister) for promoting interaction and applied it to learners. As a result, we have acquired positive results of robot programming education using Web2.0 tools. Most participants were evaluated that Web2.0 tool would be helpful to the overall robot programming course.
