기후요소를 고려한 초고층 건설공사의 타워크레인 양중시간 예측 시뮬레이션 모델
양강혁,이현수,박문서,정민혁,황성주,Yang, Kanghyeok,Lee, Hyun-Soo,Park, Moonseo,Jung, Minhyeok,Hwang, Sungjoo 한국건설관리학회 2013 한국건설관리학회 논문집 Vol.14 No.2
초고층 건물공사에서 타워크레인의 양중계획은 전체 공사의 성패를 좌우할 수 있는 매우 중요한 요소 중 하나이다. 타워크레인의 양중계획에 있어 양중시간은 기본적인 요소 중 하나로 이를 바탕으로 양중부하 및 타워크레인을 선정하기 때문에 양중계획을 위해서는 정확한 양중시간의 예측이 필요하다고 할 수 있다. 현재 초고층 공사의 양중시간 예측은 기존의 실적자료와 시뮬레이션을 이용하여 수행하고 있지만 양중작업에 영향을 미치는 환경적인 요인에 대해서는 충분히 고려되지 못하고 있다. 따라서 본 연구에서는 양중작업에 영향을 크게 미치는 바람을 시뮬레이션에 반영하여 초고층 공사의 타워크레인 양중시간을 예측하는 시뮬레이션 모델을 개발하였다. 시뮬레이션 분석 결과 바람의 영향을 반영한 양중시간은 높이가 올라갈수록 증가하였으며, 초고층부의 경우 기계적 양중시간보다 바람의 영향에 의한 양중 지연시간이 더 크다는 것을 알 수 있었다. 또한 연구 대상지인 서울의 풍속은 4월이 강하고 10월이 약하게 나타났으며, 양중시간을 예측한 결과 둘 간의 큰 차이가 발생함을 알 수 있었다. 이 같은 결과는 향후 초고층 타워크레인 양중계획 시 바람이 양중에 미치는 영향을 예측하고 이를 고려하여 실제 상황과 동일한 양중계획을 세우는데 활용될 수 있을 것으로 기대된다. Tower crane hoisting plan is one of the key element for the success of entire High-Rise Building construction. Hoisting time is the basic factor to appropriate hoisting plan which need to the hoisting load estimate and tower crane selection. With this reason, accurate hoisting time is needed to the proper hoisting plan. The current hoisting time estimation for High-Rise Building focus on the hoisting cycle time estimation with historical data. However, this method underestimated the external influences like environmental factor. Thus, this paper aims to develop the hoisting time estimation model with discrete event simulation which include the wind influences with certain height. According to the simulation result, the hoisting time which applied wind influence is increasing with height growth. Because of the high speed wind, the upper area of building has more operation delay time than the mechanical operation time. Seoul, the research area, has the most fastest wind speed on April and the least on October. Due to these differences of wind speed, the hoisting time is estimated with significant differences between April and October. This hosting time estimation model would be used for estimating the influence of wind. Moreover, this could apply to make the realistic hoisting plan.

연구목적: 본 연구의 목적은 노인장기요양보험제도 내에서 방문재활서비스 도입과 활성화를 위한 근거자료를 마련하는데 목적이 있다. 연구방법: 문헌연구를 통해 한국의 노인장기요양보험, 방문재활 서비스의 정의와 문제점, 선진국의 방문재활 사례를 검토하였고, 이를 바탕으로 하여 방문재활 서비스의 도입과 활성화의 근거를 마련하기 위해 연구하였다. 연구결과: 2009년 10월 노인장기요양보험 서비스 이용현황은 79.3%가 장기요양급여를 이용하였다. 2008년 요양 시설은 171%증가, 재가기관 현황은 263%증가 되었다. 재가서비스 중 방문요양과 주간 보호가 가장 많았다. 2010년 복지용구에 사용된 금액은 전년대비 129억원이 증가되었다. 하지만 신체적 능력 향상 및 회복을 촉진하여 일상생활수행능력의 극대화를 돕는 방문재활서비스(작업치료, 물리치료)는 재가급여 항목에 포함되어있지 않다. 결론: 높아져가는 노인 인구와 만성 질환자를 위해 방문 재활서비스가 필요하다. 일상생활수행능력의 극대화를 위해 재활인력 및 서비스 종류 증대 복지용구 사용에 관한 교육, 그리고 장기요양보험 내 등급외자에게도 서비스를 제공하여야 한다. 이를 위해 선진국의 방문재활 사례를 충분히 검토해야 할 것이다. Objective: This study aims to provide the ground for introduction and vitalization of home rehabilitation service in public long-term care insurance Methods: We reviewed that Korea public long-term care insurance, definition and problem of home-based rehabilitation and a case of home-based rehabilitation in advanced nations through a study of literature, which is a basis that offers introduction and vitalization of home-based rehabilitation. Results: Long-term Care Insurance for the Aged presents Long-term Care Insurance is used 79.3% at Sep. 2010. Respectively, Nursing facility and home-based service facility are increased at 171/%, 263% in 2008 when compared in 2007. Home-in visitation care and daycare is very common among Home-care service. The money that is used for welcare product is increased when compared previous year, that is One thousand Two hundred ninty million wons. However, home-based rehabilitation service(Occupational and physical therapy) that facilitates physical capability and recovery and helps maximize Activity Daily Life ability is not included in Home-in pay item. Conclusion: Home rehabilitation service is necessary for patients of chronic disease and a increasing number of older-aged people. It is also provided to not-included people in-Long-term Care Insurance for the Aged for education of welcare product use, rehabilitation staff and a kind of service increases to maximize activity daily life ability, And for this, we should review thoroughly a case of Home rehabilitation service in developed country.

Recent studies have demonstrated the association between allergic diseases and vitamin D deficiency. In addition to its classical role in calcium homeostasis, vitamin D has been known for its effect on immunomodulation. Because immunologic mechanisms play a role in the pathogenesis of atopic dermatitis (AD), vitamin D may influence the activity of AD. Epidemiological studies, clinical studies, and in vitro studies have suggested that vitamin D may improve the symptoms of AD. The purpose of this paper is to review the present literature that suggests a potentially significant role for vitamin D in AD. (Allergy Asthma Respir Dis 2013;1:197-202)

본 연구는 수원시 도심에 위치한 도시공원인 효원공원을 대상으로 여름철 대기온도 저감효과를 확인하고, 공원을 구성하는 서로 다른 피복유형별 특성을 파악하기 위하여 열 환경을 실측하고 분석하였다. 도시공원의 여름철 대기온도저감효과는 도심주거지 (매탄동) 대비 평균 4.4-4.5%로 통계적으로 유의하였고 (p< 0.001), 수원시의 외곽주거지 (상광교동) 보다는 약 0.8% 낮은 수준이었다. 도시공원 내 피복유형 (보도 블럭, 잔디 식재지, 소나무-잔디 식재지, 수목 차광지 및 혼합림 조경지)에 따른 열환경은 자연소재의 유형일수록 일평균기온, 일최고기온, 여름일수가 낮은 경향을 보였다. 그러나, 일최저기온 및 열대야일수는 피복유형에 따른 상관관계가 뚜렷하게 나타나지 않았다. 오후시간대 (13:00-15:00)에 혼합림 조경지, 수목 차광지, 소나무-잔디 식재지의 불쾌지수 (DI), 습구흑구온도 (WBGT) 및 열지수 (HI)의 평균값이 보도 블록과 잔디 식재지보다 낮아서 자연소재의 피복 유형의 열쾌적성이 양호한 것으로 나타났다. 그러나 각 지수에 대한 등급은 모든 피복 유형에서 '가장 높음' 또는 '주의' 단계로 동일하였다. 한편 오전 (06:00-08:00)에는 토지 피복유형별 열쾌적성에 차이가 없었다. 결론적으로 도시에서 열 환경을 개선하기 위하여는 초지, 숲 및 개방 지역의 토지 피복 유형을 증가하여야 한다. This study was conducted to analyze the effect of the different land covers of an urban park (Hyowon park) in downtown Suwon on the urban thermal variations during a hot summer. The effect of the air temperature reduction in the urban park was 4.4%-4.5% for the downtown residence (Maetan-dong). This value was about 0.8% lower than that of the outskirts residence (Sanggwanggyo-dong). The daily mean temperature, daily maximum temperature, summer day and heat wave frequency were measured under the different land covers (cement-block, grass, pine-grass, shading area and mixed forest) showed these values generally decreased under natural land cover types. Daily minimum temperature and tropical night frequency didn't seem to correlate with the land cover types. Means of thermal comfort indices (wet bulb globe temperature, heat index and discomfort index) in the shading area, mixed forest and the pine-grass types were lower than those of cement block and grass types. However the levels of those indices were equal to 'very high' or 'caution' levels in the afternoon (13:00-15:00). In the morning (06:00-08:00), thermal comfort indices of the urban park didn't correlate with land cover types. Therefore, to reduce heat stress and to improve the thermal comfort in urban parks, an increase in the area of natural land cover such as grass, forest and open spaces is required.

Purpose: The prevalence of atopic dermatitis (AD) has been increasing in many developed countries including Korea. There has been little information on the status of real clinical practice for atopic dermatitis by physicians in Korea. Methods: This study investigated the current status of clinical practice on allergy test and treatment of AD in Korea by analyzing a questionnaire survey of 155 physicians who attended the educational program for practical management of AD by the Korean Academy of Asthma, Allergy and Clinical Immunology. The questionnaire was mainly composed of 20 items regarding diagnosis, treatment of AD. Results: Among the 155 physicians who completed the questionnaire survey, most of subjects (90%) agreed that allergy test was necessary, but only 68% performed allergy test in their practice for AD. The barriers to allergy testing were lack of test personnel or facilities (61%), disbelief on the clinical importance of allergy test in the treatment (41%), and difficulty in explanation about the test results to patients (16%). Problems interfering the active treatment of patients with AD were the difficulty in acquiring a sufficient time for education and explanation about treatment (54%), incomplete clinical efficacy of current medication and concern on the side effects (41%), and the difficulty in establishing a good doctor-patient relationship (40%). Conclusion: There are difficulties of physicians in the active management of AD in Korea. To solve current difficulties, changes in medical system to encourage the physicians’ effort for active clinical practice for patients with AD and education for physicians are needed.
