Asthma is the most common disease of the lungs, and one that poses specific challenges for the physicians including radiologist. This article reviews for the clinical diagnosis, Radiologic features, and differential diagnosis of asthma, and outlines the radiologic features of the complications of asthma. Bronchial wall thickening and hyperinflation characterize the chest radiograph of the patients with asthma. On CT scan one may see airway wall thickening, thickened centrilobular structures, and focal or diffuse hyperlucency. Apparent bronchial dilatation may be seen, but the diagnosis of bronchiectasis should be made with caution. Quantification of changes in the airway wall and lung parenchyma may be valuable in understanding the mechanisms of asthma and in evaluating the effects of treatment. The challenge for the physician evaluating the images of a patient with asthma is to find complications. (Tuberc Respir Dis 2005; 59: 591-599)

Air transportation demand is consistently increasing in Korea due to economic growthand low cost carriers. For this reason, airport expansion plans are being discussed in Korea. Therefore, it is essential to forecast reliable air transportation demand with adequatemethods. However, most of the air transportation demand models in Korea has beendeveloped by simple regression analysis with several dummy variables. Simple regressionanalysis may occur spurious regression which means between explanatory variables anddependent variable do not have direct causal relationship, yet it may be wrongly inferredthat they do, due to trend of variables seems similar. In this paper, we developedeconometric model for air transportation demand based on stationarity in time-series data. Unit root test and co-integration test are used for testing hypothesis of stationarity. 우리나라 항공 여객수요는 2014년 기준 국제선 5,700만명, 국내선 2,400만명에 도달하였으며, 지속적인 증가 추세를 보일 것으로 예상되고 있다. 이에 따른 국내 공항시설들의 확충 계획이 활발히 진행되고 있으며, 이를 위해 선행적으로 항공수요 예측을위한 모형 개발이 필요하다. 우리나라에서는 국내총생산을 설명변수로 한 계량경제모형을 주로 항공수요 모형으로 이용하고 있으며, 시계열 자료의 안정성을 고려하지 않을 때 발생하는 허구적 회귀 현상에 대한 많은 논의가 이루어지지 않은 상태이다. 본연구에서는 시계열 자료의 안정성을 고려한 항공수요 계량경제모형을 개발하였다. 시계열 자료의 특성을 검정하기 위한 단위근 검정과 변수들 간의 장기균형관계를 분석하기 위한 공적분 검정에 대한 이론적 고찰을 수행하였다. 마지막으로, 시계열 자료의 안정성을 고려한 항공수요 계량경제모형 개발 프로세스를 정립하였다. 정립된 프로세스의적용 가능성을 검증하기 위해 제주공항 국내선 수요를 대상으로 항공수요 모형을 산정하였다. 수요 모형의 설명변수는 국내총생산과 항공요금지수를 이용하였으며, 기존 항공수요 계량경제모형에서 발생하는 문제점을 해소한 것으로나타났다.

Each exercise had self-servant and was carried out 60 minutes with teaching method of special directors in every weep Physique by height, weight, condition of exercise ability by the capacity of the lungs of the heart and lung endurance and intake of the maximum oxygen, muscular strength of stomach, grasping power, pliability by forward bending with the upper part of the body, instantaneous force of muscle in a sudden jump, muscular endurance by put-up and sit-up, agility by side-step and response of the whole body, and balance by one leg standing while closing eyes as using Helmas (sewoo systems korea) were measured. The Results, 1.There is a significant difference for both men and women in the capacity of the lungs and the heart and lung endurance, However only women have a significant difference in intake of the maximum oxygen. 2. Both men and women have a significant difference in muscular strength of stomach and grasping power to measure muscular strength. 3. Both men and women have a significant difference in forward bending with the upper part or the body to measure flexibility. 4. Sudden jump to measure instantaneous force of muscle, sit-up, and push-up to measure muscular endurance show that both men and women have a significant difference.(p<.01) 5. Side-step and response of the whole body to measure agility show that both men and women have a significant difference. 6. One leg standing with closing eyes to measure balance show that both men and women have a significant difference.

도시형 생활주택 화재안전성 측면에서 실태 연구

박재성 한국방재학회 2016 한국방재학회논문집 Vol.16 No.5

Urbanistic housing was newly established from May, 2009 to supply housing to small-size households in cities. In the process, several regulations related to fire safety were unshackled without reasonable precautions. As a result, fire often broke out in urbanistic housing such as the fire accident in Daebong Green Apartment Uijeongbu-si, and fire spread to adjacent buildings, resulting in serious damages. Although the government has reinforced some regulations of fire safety, it does not meet expectation because it still fails to secure reasonable fire safety measures. The present study carried out the status survey of urbanistic housing, and reviewed and analyzed applicable laws and regulations to find weak points and problems in fire safety such as fire spread and egress. The status survey found that urbanistic housing is exposed to many safety issues such as difficult access of fire engines, fire spread to neighboring buildings, and unsafe egress stairs. Therefore, it is necessary to prepare desirable corrective measures. 도시형생활주택은 도시에 거주하는 소규모 가구의 주택공급을 위하여 2009년 5월부터 도시형생활주택 제도를 신설하면서 화재안전에 영향을 미치는 각종 규제를 합리적 대책 없이 완화해주었다. 그러한 결과로 의정부대봉그린아파트 화재 등 도시형생활주택에서 화재가 자주 발생하고 인접 건축물로 연소확대 등 많은 피해를 발생시키고 있다. 정부에서는 일부 화재안전과 관련한 기준을 강화하였지만 합리적 화재안전성을 확보하기에는 여전히 미흡한 실정이다. 본 연구에서는 도시형생활주택에 대한 실태조사, 관련 법규정 등을 분석하여 연소확대, 피난 등 화재안전성 측면에서의 취약요소와 문제점을 도출하였다. 실태조사 결과에 의하면 소방차의 원활한 진입, 인접 건축물과 연소확대 방지, 피난계단의 안전성 등에서 많은 문제를 그대로 내포하고 있어 이에 대한 합리적 개선대책 마련이 필요한 것으로 분석되었다.

The purpose of this study was to examine the effect of motor exercise program on the cognitive of children with developmental disabilities. The subjects in this study were six selected children who were attending special school in the city of Busan. To gauge the level of improvement in their cognitive competence, KEN-MSC was put to use. To find out any change of their cognitive competence, motor exercise program executed to children two times a week, and forty minutes a day over twenty weeks. Before applied this program, measured the cognitive competence for each group, and after twenty weeks by same method like before, and the results of the comparisons were as follows ; 1. The experimental group was improved missing search among cognitive competence. 2. The experimental group was improved order assembly among cognitive competence. 3. The experimental group was improved block design among cognitive competence. 4. The experimental group was improved object assembly among cognitive competence. 5. The experimental group was improved sign writing among cognitive competence. 6. The experimental group was improved labyrinth among cognitive competence.

공동주택 소방안전관리 실태에 관한 연구

박재성,Park. Jae Sung 한국방재학회 2013 한국방재학회논문집 Vol.13 No.1

공동주택은 우리나라 주거형태의 절반 이상을 차지하고 있으며, 공동주택에서의 화재발생과 그로인한 인명피해는 국가적 중요한 문제이다. 공동주택의 화재안전성을 향상시키기 위해서는 화재안전관리를 포함하여 전체적인 시설관리를 1차적으로 책임지고 있는 소방안전관리자의 화재안전의식 및 대응능력의 강화가 무엇보다 중요하다고 하겠다. 공동주택 소방안전관리자가 소방시설을 중심으로 화재안전에 관하여 정확히 파악하고 운용할 수 있는 능력을 갖춘다면 화재발생시 소방시설을 작동하지 못하거나 아니면 소방시설이 제대로 작동하지 않아 발생하는 2차적인 피해는 최대한 줄일 수 있을 것이다. 본 연구에서는 공동주택의 화재발생 통계, 법규정, 소방안전관리자에 대한 설문조사 등을 통해 공동주택 소방안전관리의 특성과 문제점 등에 대해 분석하였다. 효율적 공동주택 소방안전관리를 위해서는 소방안전관리자의 직무능력 향상을 위한 전문적이고 체계적인 교육, 관련 제도의 개선, 거주자에 대한 교육과 홍보가 필요한 것으로 분석되었다. Apartment occupies more than half of the nation`s residential forms, so the fire in apartment and the resulting casualties are the national importance. In order to improve the fire safety of apartment, fire protection awareness and strengthening of response capacity of fire wardens who are primarily responsible for overall facility management including fire safety management are more important than what will be. If fire wardens of apartment understand the fire safety, especially fire-fighting facilities and prepare the ability to operate those, secondary damage by not being able to operate those or not proper operation of those will be much lessened. This study analyzed the characteristics and problems of Fire protection control of apartment through fire statistics, laws and regulations and the survey to fire wardens. It also analyzed that the professional and systematic training to enhance fire wardens` duty capacity, improvement of related system and the education and promotion for residents are to be accompanied.
