The nuclear licensee must ensure that the nuclear or radiological emergency preparedness and response organization is explicitly defined and staffed with adequate numbers of competent and assessed personnel for their roles. This paper describes the responsibilities of medical and support personnel for the medical action of casualties in the event of a radiological emergency at the KAERI. Currently, there is one medical personnel (nurse) in KAERI, and a total of eight medical support personnel are designated for medical response in the event of a radiological emergency. These medical support personnel are designated as one or two of the on-site response personnel at each nuclear facility, operating as a dedicated team of A, B (4 people each). In the event of a radiological emergency, not all medical support personnel are mobilized, but members of the dedicated medical team, which includes the medical support personnel of the nuclear facility where the accident has occurred, are summoned. Medical and support personnel will first gather in the onsite operational support center (OSC)/technical support center (TSC) to prepare and stand by for the medical response to injured when a radiological emergency is declared. They should take radiation protective measures, such as wearing radiation protective clothing and dosimeters, before entering the onsite of a radiological emergency, because injuries sustained during a radiological emergency may be associated with radioactive contamination. In the event of an injury, direct medical treatment such as checking the patient’s vitals, first aid, and decontamination will be carried out by medical personnel, while support personnel are mainly responsible for contacting the transfer hospital, reporting the patient’s condition, accompanying the ambulance, filling out the emergency medical treatment record, and supporting medical personnel. In order to respond appropriately to the occurrence of injuries, we regularly conduct emergency medical supplies education and medical training for medical support personnel to strengthen their capabilities.

목적 : 본 연구는 직업복귀프로그램에 참여한 산업재해근로자를 대상으로 원직무복귀에 미치는 요인을 알아 보고자 하였다. 연구방법 : 2014년 11월부터 2016년 8월까지 경상남도 소재의 C병원에서 직업복귀프로그램에 참여한 산업 재해근로자 92명을 대상으로 인구사회학적 요인, 산업재해관련 요인, 직업관련 요인, 직업복귀프로그램 요인들이 원직무복귀에 미치는 효과를 분석하였다. 결과 : 산업재해근로자의 원직무복귀에 미치는 요인을 분석한 결과 인구사회학적 요인에서는 나이, 산업재해 관련 요인에서는 산업재해요양기간, 통증, 직업관련 요인에서는 고용형태, 작업강도, 직업복귀프로그램 관련 요인에서는 작업능력평가 결과, 작업능력강화프로그램 시작시기가 상관관계가 있었으나 적용기간은 상관관계가 없었다. 결론 : 본 연구는 산업재해근로자들이 나이가 적고, 산업재해요양기간이 짧고, 통증이 적을수록, 고용형태가 정규직이거나 작업강도가 낮을수록, 작업능력평가결과가 좋거나 직업복귀프로그램 시작시기가 빠를수록 원직무복귀를 높일 수 있음을 지지하였다.

The maxillofacial region is susceptible to damage because facial bone is prominent. The aim of this study is to evaluate the incidence, etiology, seasonal distribution, and patterns of maxillofacial injuries and investigate the percentage of bone fractures on CT scans by patient’s gender and age. Electronic medical records of 1,483 patients who had maxillofacial injuries and visited the Emergency Medical Center of Chonnam National Hospital were evaluated. Age, gender, etiology, seasonal occurrence, frequency of fracture, and the pattern of bone fracture were analyzed by using IBM SPSS Statistics 21 (SPSS Inc., Chicago, IL, USA). Male to female ratio was 2.82:1. The most common causes of injury were falls or collisions (male 40.09%, female 48.2%), followed by traffic accidents and violence. The number of injuries related to sporting accidents, assult, and industrial accidents was higher in male patients than that of female patients. With regard to the seasonal occurrence, 434 cases (29.26%) occurred in the summer, while 306 cases (20.63%) occurred in the winter. In this study, 946 patients (63.79%) were identified to have facture and 537 patients (36.21%) were found to be without fracture on CT scans. The orbital bone (41.38%) was the most commonly fractured in the mid facial structures. The most common fracture site in the mandible was the body of the mandible (23.13%). The patterns of maxillofacial injuries were various based on gender, age, cause of injury, and season.

Self-efficacy (one's perceptions of their capability to perform a task) plays an important role in work-related performance and motivation. For example, self-efficacy is known to have much influence on job performance, job satisfaction, motivation, etc. As such it is important to know what factors collectively enhance the selfefficacy of employees, so that injured workers contribute to the organization they belong to after they come back to their workplace. The aim of this study is to identify such industrial accident-related factors and extract rules among the factors in order to establish self-efficacy enhancement strategies for injured workers. In this study, a binary decision tree model for self-efficacy prediction was built using a panel data provided from Korea Workers’ Compensation & Welfare Service. As a result, eight variables with the largest influence on self-efficacy were selected in the prediction model, and it correctly classified 70.1% of instances. The result suggests social support during the treatment period and offering paid time off such as vacation leave, sick leave and bereavement leave are important factors to enhance self-efficacy that will improve the work performance of injured workers.

A 78 year-old male complained of mild pain at a gingival mass on his anterior mandible, injured and ulcerated by autobicycle accident six months ago. He had suffered from uncontrolled diabetes. The tumor specimens from his chin and gingiva were examined by immunohistochemical method, and their microsections showed poorly differentiated polygonal tumor cells, occasionally formed ductal structures. The tumor cells grew infiltratively into adjacent fibromuscular tissue with frequent atypical mitosis, exhibiting the features of poorly differentiated adenocarcinoma. However, in the computed tomography(CT) view a tumor mass was also found in his lung, and diagnosed lung cancer. In the immunohistochemical observation the tumor cells were strongly positive for thyroid transcription factor 1(TTF-1), cytokeratin 7, PCNA, p53, and PIM-1, occasionally positive for p63, but sparsely positive for survivin. The tumor cells were almost negative for S-100, cytokeratin 14, and α-SMA, while the vascular structures in the tumor tissue were conspicuously demarcated by the stains of α-SMA. Taken together, the present case was finally diagnosed poorly differentiated adenocarcinoma, metastasized from lung adenocarcinoma. And it was presumed that the metastatic tumor cells tended to be anchored in the traumatized area of anterior mandible, where the wound healing was undergoing with de novo angiogenesis and the activation of different cytokines and growth factors

This study assessed the efficacy of aqueous chlorine dioxide (CIO2) and commercial chlorine sanitizer in terms of its ability to eliminate Listeria monocytogenes, Salmonella Typhimurium, and Escherichia coli 0157:H7 on radish sprouts (Raphanus sativus L.). Radish sprouts were inoculated with a cocktail containing one each of three strains of three different foodbome pathogens, then treated with distilled water (control) or chemical sanitizers (100 ppm commercial chlorine, and 50, 100, 200 ppm CIO2) for 1, 5, and 10 min at room temperature (22士2℃). Populations of S.Typhimurium, E. coli 0157:H7 and L. monocytogenes were counted at 4.64, 6.05, and 4.29 log CFU/g, respectively, after inoculation. Treatment with water did not significantly reduce the levels of any of the three foodbome pathogens. The levels of all three pathogens were reduced by treatment with chemical sanitizers; however, the observed 1evels of reduction of E. coli 0157:H7 and L. monocytogenes were not significant as compared with the controls. The levels of the three pathogens were reduced most profoundly when treated for 10 min with 200 ppm of CIO2, and the reduction levels of S. Typhimurium, E. coli 0157:H7, and L. monocytogenes were 1.17, l.63, and 0.9610g CFU/g, respectively. When chemically injured cells were investigated using SPRAB for E. coli 0157:H7 and by selective overlay methods for S. Typhimurium and L. monocytogenes, respectively, it was noted that commercial chlorine sanitizer generated more numbers of Í넌red pathogens than did CIO2. These data indicate that CIO2 treatment may prove useful in reducing the numbers of pathogenic bacteria in radish sprouts.

ASIA 근력점수로 각각의 손상레벨별 SCIMⅡ 최고 점수를 예측하는 회귀식을 이용하여 척수손상-기능실현평가지수를 쉽게 계산할 수 있는 추정식을 구하였다. 추정식에 의해 구한 기능실현평가지수 값과 기능실현평가지수 정의에 의해 구한 기능실현평가지수 값 사이에 높은 상관관계(r=.723, p<.05)를 보였다. ASIA 근력점수, 나이, 손상원인, 재활기간, 손상레벨과 기능실현 평가지수 값 사이에는 유의한 상관관계가 없었다. 결론：ASIA 척도 A-C인 경우의 만성 척수손상환자들에게서 구한 척수손상-기능실현평가지수 추정식은 신뢰도와 타당도가 높았으며, 이 추정식을 이용하여 만성 척수손상환자의 기능변화 및 재활치료효과를 객관적으로 측정하는데 효과적임을 알 수 있었다. 또한 SCIMⅡ 평가 점수의 결과 해석을 위해 개개인의 SCIMⅡ 점수를 손상레벨별로 비교할 수 있는 기준 자료가 될 수 있음을 알 수 있었다.

Many researches have been focused on the analysis of industry disasters in order to reduce them. As a similar endeavor, this paper provides a propensity analysis of injured people from various industries using classification and regression tree(CART), a data mining algorithm. The sample for this work was chosen from 25,157data related to various industries during one year ( 2003.2~2004.1 ) at Kangwon-Do in Korea. For the purpose of this paper, eight independent variables (injured date, injured time, injured month, type of Injured person, continuous service period, sex, company size, age)are taken from injured person group. According to the analysis result, it is found that five out of the eight factors that are predicted as significant have salient effects. Factors of season, time/hour, day of the week, or month which disasters happened do not show any significant effect. This paper provides common features of injured people. The provided analysis result will be helpful as a starting point for root cause analysis and reduction of industry disasters and also for development of a guideline of safety management.

고도화된 산업의 발달로 인하여 많은 업종들이 생겨나게 되었고, 그로 인해 크고 작은 사고들이 발생하게 되었다. 사고의 발생은 부상, 사망과 질병 등의 재해자들을 발생시키고, 사고로 인한 재해자의 수는 한 사업장에서도 여러 건씩 발생한다. 이러한 재해자의 공통된 특성 요소와 성향을 분석할 수 있다면, 1%의 재해자라도 더 줄일 수 있으리라 사료된다. 본 논문에서는 업종별 그룹을 통해 재해자들의 특성화 분석을 위하여 총 25,157개의 데이터를 바탕으로 데이터 Mining 기법중의 하나인 Classification and Regression Tree(CART)를 이용하여 분석을 하였다. 종속변수인 10개의 주요 업종을 중심으로 재해자들이 어떠한 성향을 나타내고 있는지 알아보고자 독립변수인 재해자 구분, 재해시간, 근속기간, 성별, 회사 규모와 연령 등 8개 항목을 채택하여 재해자 위험 그룹을 분석하고 그 결과를 제시한다.

For the accident prevention, it is necessary to identify common factors and characteristics contributing to the industrial accidents. This study concerned with the accident characteristics by age of injured person in the manufacturing industries. To make the statistical comparisons for the accident characteristics by age group, we derived the distributions of occupational injuries in terms of accident time, accident type, activity at time of accident, injury type, injured part of body, agency of accident, and workday losses. The results show that the characteristics of the occupational injuries by age group are not significantly different in a31 characteristics investigated in this study.

The purpose of this study was to determine the validity and the of the Neurobehavioral Cognitive Status Examination(NCSE) to ascertain its value in the cognitive functional evaluation of brain-injured patients. The NCSE, uses as an independent test to evaluate cognitive function within five major areas: language, construction, memory, calculation, and reasoning. And the examination separately assesses levels of consciousness, orientation, and attention. The instrument quickly identifies intact areas of functioning, yet provides more detailed assessment in areas of dysfunction. The level of cognitive is classified as unimpaired and mild, moderate, severe impaired. Standardization data are provided for 42 braininjured patients, age ranged from 24 to 76 years. In the validity study, the NCSE subtest was significantly correlated with associated Mini Mental State Examination-Korean version(MMSE-K) test, except for attention, naming, construction. The specificity score of the traumatic brain-injured patients were higher than those of the stroke patient group in attention, construction, calculation. The mean score of stroke patients were significantly higher than those of the traumatic brain-injured group in orientation. In the inter-rater and test-retest reliability, the screen Kendall's τb and Metry pearson's correlation statistics were indicating a good internal consistency. The NCSE demonstrated an acceptable validity and reliability for the evaluation of cognitive functional capacity of brain-injured patients in clinical practice.

This purpose of this study was to determine the best enrichment medium for rejuvenating and recovering Salmonella placed in cold temperature prior to the employment of the gold biosensor combined with a light microscopic imaging system. A mixture of nalidixic-resistant Salmonella Typhimurium and Enteritidis were inoculated onto chicken (1,000 CFU/chicken). After cold injury at 4℃ for 24 hr, Salmonella on chicken was enriched for 6 hr with six non-selective media including buffered peptone water broth, lactose broth, brain heart infusion broth (BHI), universal pre-enrichment broth, nutrient broth, and tryptic soy broth, and five selective media including brilliant green broth (BG), rappaport-vassiliadis R10 broth, selenite cystine broth, selenite broth, and tetrathionate brilliant green broth (TBG) for the comparison of Salmonella growth. Various concentrations of Salmonella (10, 50, 100, 500, and 1,000 CFU/chicken) were then enriched for 6 hr in both BHI and BG media to select the best media. BHI was selected as the most effective non-selective enrichment medium, while BG was selected as the most effective selective enrichment medium. Finally, BHI medium was selected as the most efficient enrichment medium for Salmonella growth injured from cold temperature during processing or storage.
