이순범,김은미,공하성 한국인터넷방송통신학회 2022 International journal of advanced smart convergenc Vol.11 No.4

Life safety awareness level diagnosis is necessary for customized safety education and continuous safety awareness. As the starting stage of safety education for each life cycle, a scale that has verified the reliability and validity of high school students' life safety awareness has not yet been developed. In this context, the purpose of this study is to develop and validate the life safety awareness scale of high school students and to analyze interindividual differences. Questionnaire data was collected from April to June 2022 from 834 students in the first, second, and third grades of high schools in △△ city in Jeollabuk-do. A final 25-item scale was developed using the preliminary survey, preliminary test, the main test, descriptive statistical analysis, and exploratory and confirmatory factor analysis. This scale consists of four sub-factors: 'safety prevention', 'safety knowledge', 'safety preparation', and 'safety protection'. Good reliability and validity were verified by analysis of content validity and construct validity. The generalizability of the scale was verified by crossover validation between the search group and the crossover group. Based on the interindividual differences analysis, although there was a difference between genders in life safety awareness, there was no difference by grade level and academic achievement. This study is significant in developing the first valid scale that can measure high school students' life safety awareness and providing the necessity and rationale for life safety education by life cycle considering individual gender differences.

고등학교 복도 보행 장애물이 피난 안전성에 미치는 영향

이순범 한국안전학회 2023 한국안전학회지 Vol.38 No.2

This study analyzes the effects of personal lockers, drinking fountains, and all-in-one shutters (hereinafter referred to as “corridor walking obstacles”) on evacuation safety to suggest the necessity of operating a more effective educational facility safety certification system. To achieve this purpose, the five-story high school building with the obstacles installed in the corridor has been chosen, and evacuation tests through the Pathfinder Simulation Program have been carried out. When the evacuation exit is designated in the current state, where the students are placed on the 2nd, 3rd, and 4th floors and the corridor walking obstacles are applied as a variable, the required safe egress time (RSET) is 322 seconds. This can lead to dangerous results in the event of a disaster by exceeding the available safe egress time (ASET) standard of 240 seconds by 82 seconds. When students are placed on the 1st, 2nd, and 3rd floors under the same conditions, the RSET is 214.5 seconds, 25.5 seconds lower than the ASET standard, indicating that it is effective in reducing the impact of walking obstacles on evacuation time. The safety management plan for walking obstacles in the corridors is discussed, considering the special characteristics of the school corridors. The results of this study can be used as the necessary data for optimizing evacuation routes in corridors and creating a safe, educational environment.

A Study on the Effects of All-in-one Automatic Fire Shutters Installed in High School on Evacuation Time

이순범,공하성,이재영 한국인터넷방송통신학회 2022 International Journal of Internet, Broadcasting an Vol.14 No.3

This study analyzed the effects of the all-in-one automatic fire shutter (hereinafter referred to as “all-in-one shutter”) installed along the fire compartment in a five-story high school building on the evacuation time by using the Pathfinder simulation program. When the all-in-one shutter was added as a new variable, the evacuation time was delayed, indicating insufficient evacuation safety. The evacuation time exceeded the appropriate standard when the evacuation exit was designated to the students in the present state of being placed on the 2nd, 3rd, and 4th floors and the all-in-one shutter was activated. When students were placed on the 1st, 2nd and 3rd floors under the same conditions, the evacuation time was also greatly exceeded. However, when the width of the entrance was set to 130cm, the evacuation time was almost the same as when the all-inone shutter was not installed. In high-rise school buildings, the bottleneck caused by all-in-one shutters is becoming a major factor in evacuation barriers. To ensure the evacuation safety of school buildings, it has been judged that evacuation education and training to predict the evacuation time required through the allin- one shutter entrance and induce an evacuation procedure suitable for the standard evacuation time should be carried out in parallel. The implications of this study and suggestions for effective fire compartments and follow-up studies were discussed.

이순범,강소영,유지숙 대한소아청소년과학회 2005 Clinical and Experimental Pediatrics (CEP) Vol.48 No.5

Purpose:Long-term administration of anticonvulsants in children with epilepsy may cause short stature, hypocalcemia and low bone mineral density. This study was performed for the early detection of abnormal bone metabolism in children with epilepsy on taking anticonvulsants. Methods:Thirty children aged 5 to 16 years who were diagnosed with epilepsy were enrolled in this study. All had taken anticonvulsants for more than one year. Bone mineral density of lumbar vertebra was measured by dual-energy X-ray absorptiometry. Serum calcium, phosphorous, alkaline phosphatase, 25-hydroxycholecalciferol[25(OH)D3], parathyroid hormone, and urine deoxypyridinoline were measured as biochemical bone markers. Bone age and body mass index were also calculated. Results:Bone minreal density, body mass index, bone age, and height were significantly decreased in two female patients who had taken two antiepileptic drugs for more than four years and they also had chronic diseases such as cerebral palsy with microcephaly, encephalomalacia, and microcephaly with atrial septal defect. Bone mineral density had significant positive correlations with body mass index(P<0.01) and bone age(P<0.01). Conclusion:This study showed chronic medication of anticonvulsants in children may cause low bone mineral density and short stature. Bone age and body mass index could be the important surrogate markers to find the population at risk. More studies, including a large study population and long term cohort study, will be required. 목 적 : 소아 간질 환아에서 장기간 항경련제를 투여시 저신장, 저칼슘혈증, 골밀도 저하가 올 수 있는 것으로 알려져 있다. 저자들은 골밀도 및 골표지자의 연구를 통해 항경련제 투여 환아의 골대사 질환의 위험을 조기 발견할 수 있는지 알아보고자 하였다. 방 법 : 간질로 단국대학교병원 소아과에서 12개월 이상 항경련제 치료를 받고 있는 환자들 중 5-16세의 환아 30명을 대상으로 2003년 7월부터 2004년 2월 사이에 본 연구를 시행하였다. 대상 환아들을 carbamazepine과 valproic acid를 단독 투여군과 2가지 이상의 항경련제를 병합투여한 군으로 나누었고, 요추부 골밀도, 체질량지수, 골연령 및 골표지자들을 측정한 후, 남녀별, 연령별로 분류하여 대조군과 비교하였다. 결 과 : 총 30명이었으며, 검사 당시 평균연령은 10.4±3.1세(5-16세)이었다. Carbamazpine 단독 투여군 10명, valproic acid 단독 투여군 6명, 2가지 이상의 약물을 투여 받은 복합 투여군이 14명이었고 복합 투여군 중에는 뇌성마비 2명, 소두증 2명, 뇌연화증 1명, 선천성심장병 1명이 포함되었다. 각 투여군 간에는 요추 골밀도, 칼슘, 인, 알칼리성 인산화효소, 25(OH)D3, 오스테오칼신, 부갑상선호르몬, deoxypyridinoline, 골연령 등의 차이는 없었다. 남녀별, 연령별로 나누었을 때 5세 및 15세 여아에서 -2.5 SDS 미만의 의미있는 골밀도의 감소를 보였으며, 체질량지수는 5 percentile 미만의 현저한 감소를 보이고 있었고, 골연령 및 신장도 감소되어 있었다. 이러한 감소를 보인 두 명의 환아 중 5세 환아는 심방중격결손증 및 소두증을 가지고 있었으며 15세 여아는 뇌성마비 및 뇌연화증이 있었고 좌하지 골절의 기왕력이 있었으며 두 환아 모두 2가지 항경련제를 4년 이상 투약 받았다. 골밀도는 체질량지수 및 골연령과 통계적으로 의미있는 양의 상관관계를 보였다. 결 론:장기간 항경련제를 복용하는 소아환자들에 있어 특히, 신체활동이 제한되어 있거나 다른 만성질환을 동반한 경우에는 골대사에 대한 세심한 주의가 필요하며 주기적으로 키, 몸무게를 측정하여 체질량지수 및 신장의 SDS를 산출하는 것이 골대사에 대한 간단하면서도 중요한 검사가 될 수 있을 것으로 생각된다.

이 연구는 패스파인더 시뮬레이션 프로그램을 활용하여 학교의 피난 안전성 확보를 위한 효율적인 학급 층별 배치 방안 분석을 목적으로 한다. 경사로와 계단이 함께 설치된 고등학교 5층 건물을 대상으로 층별 인원배치에 따른 REST (Required Safe Egress Time, 피난소요시간)을 분석하여 효율적인 피난 방법과 안전성을 평가하였다. 현재 상태의 인원배치는 기준 RSET을 초과함으로써 피난안전성에 문제가 있다는 결과를 얻었다. 학생들을 3층, 4층, 5층에 배치했을 때 기준 RSET보다 가장 많은 시간을 초과하는 결과를 얻었다. 학생들을 1층, 2층, 3층에 배치했을 때 기준 RSET보다 가장 짧게 피난을 완료하는 결과를 얻었다. 현재의 상태에서 위치별로 피난출구를 지정하여 피난을 유도했을 때 기준 RSET을 단축시키는 결과를 얻었다. 결과적으로 고층 학교 건물에 학생들을 배치할 때는 저층부터 배치하는 것이 피난안전성 측면에서 효과적이며, 화재 시 위치별로 가까운 출구를 활용하여 피난할 수 있도록 피난출구를 지정한 사전 훈련이 필요하다. 향후 연구과제로 특정 위치에 화재가 발생했을 때 해당 위치의 자동방화셔터의 개폐여부에 따른 RSET에 대한 추가적인 연구가 필요하다. This study analyzes the efficient floor layout plan of classrooms for securing evacuation stability in school in case of fire by using the Pathfinder simulation program. Efficient evacuation methods and safety were evaluated by analyzing REST (Required Safe Egress Time) according to the allocation of personnel by floor targeting a high school 5-story building equipped with a ramp and stairs. The current status of personnel assignments exceeded the Required Safe Egress Time(RSET), resulting in a problem with evacuation safety. When students were placed on the 3rd, 4th, and 5th floors, the result was that the time exceeded RSET the most. When students were placed on the 1st, 2nd, and 3rd floors, the result was that they completed evacuation in the shortest time, less than RSET. In the current state, when evacuation was guided by designating an evacuation exit depending on the location, the result of shortening RSET was obtained. As a result, it is effective to put the students on the lower floors when placing students in high-rise school buildings in terms of evacuation safety, and in the preliminary training, it is required to designate evacuation exits so that they can use the nearest exit for each location in case of a fire. As a future research project, additional research is needed on the RSET when a fire occurs in a specific location according to whether the automatic fire door at that location is opened or closed.

Mycoplasma pneumoniae 폐렴에 병발한 Guillain-Barre 증후군 및 뇌염 1례

이순범,정은희,이영석,권범선,유지숙 대한소아청소년과학회 2004 Clinical and Experimental Pediatrics (CEP) Vol.47 No.12

The most common pathogen of respiratory tract infection among school-age children and adolescents is Mycoplasma pneumoniae, which causes clinical manifestations of pneumonia, acute asthmatic attack, pharygitis, and tonsilitis. It can also cause extrapulmonary infections that involves skin, the nervous system, the digestive system, the cardiovascular system, and the hematopoietic system. It is reported that the central nervous system symptoms may occur in 0.1% to 7% of patients hospitalized with Mycoplasma pneumoniae infection. Direct invasion, toxin, immune-mediated, and vascular phenomenon have been proposed for the etiology of the neurological manifestations. We have experienced a six-year-old male patient with Mycoplasma pneumoniae pneumonia who had complained of both leg pains and immobility two weeks after the onset of pneumonia, which was confirmed as peripheral neuropathy of Guillain-Barré syndrome. Three weeks after the disease-onset, altered consciousness and seizure attacks developed and intravenous immunoglobulins infused under the impression of encephalitis induced by Mycoplasma pneumoniae infection. He showed complete recovery of running and mentality five months after the disease-onset. We herein report a case of Mycoplasma pneumoniae pneumonia complicated with Guillain-Barré Syndrome and encephalitis about 2 or 3 weeks after the disease onset with a review of literatures. 저자들은 Mycoplasma pneumoniae 폐렴으로 치료를 받던 남아에서 말초 신경계 증상인 Guillain-Barr 증후군 및 중추신경계 증상인 뇌염이 병발한 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.
