연구목적 : 지적장애인은 공존질환의 위험이 높은 것으로 알려져 있다. 본 연구에서는 지적장애인에서 동반되는 정신질환 및 신체질환의 유병률을 평가하고, 이를 일반 인구집단과 비교 하고자 한다 방 법 : 2016년 건강보험심사평가원 표본자료를 이용하여 분석을 시행하였고, 지적장애군 2,005명과 비지적장애군 1,467,905명이 연구에 포함되었다. 두 군의 공존질환 유병률을 구하였고, 로지스틱 회귀 분석을 통해서 비지적장애군 대비 지적장애군의 공존질환 교차비를 산출하였다. 결 과 : 비지적장애군과 비교했을 때, 지적장애군은 대부분의 정신질환이 높은 비율로 나타났다. 조현병스펙트럼장애가 20.64%로 가장 높은 비율을 보였으며, 우울장애(17.64%), 양극성장애(15.81%), 주의력결핍 과잉행동장애(13.17%), 불안장애(12.69%), 수면장애 (7.68%), 자폐스펙트럼장애(6.01%) 순서였다. 비지적장애군을 기준으로 했을 때, 지적장애군은 대부분의 정신질환에서 높은 교차비를 보였다. 자폐스펙트럼장애(OR, 113.57; 95% CI 95.24~134.56)가 가장 큰 교차비를 보였으며, 이어서 특정학습장애(OR, 84.20; 95% CI 43.76~147.47), 주의력결핍 과잉행동장애(OR, 77.70; 95% CI 69.00~87.24), 의사소통장애(OR, 51.19; 95% CI 38.06~67.32), 적대적반항장애/품행장애(OR, 49.46; 95% CI 38.13~63.05), 조현병스펙트럼장애(OR, 28.13; 95% CI 25.54~30.93) 순이었다 결 론 : 본 연구 결과 지적장애군에서 대부분의 정신질환 유병률과 교차비가 높았고, 이는 공존질환을 고려한 적절한 의학적 개입이 필요함을 시사한다. Objectives : Intellectual disability (ID) is known to be associated with an increased risk of comorbidities. We aimed to investigated the prevalence rates of comorbidities of individuals with ID. Methods : This study used data from the Korea Health Insurance Review and Assessment Service-National Patient Sample (HI-RA-NPS) for 2016. A total of 2,005 individuals with ID and 1,467,905 individuals without ID were included. The prevalence rates and odds ratios of psychiatric and medical comorbidities between two groups were analyzed. Results : The prevalence rates of comorbidities in ID group was higher across different types of co- morbidities compared with non-ID group. The comorbidities most commonly observed in ID were schizophrenia spectrum disorder (20.64%), followed by depressive disorder (17.64%), bipolar disorder (15.81%), ADHD (13.17%), anxiety disorder (12.69%), sleep disorder (7.68%), autism spectrum disorder (6.01%). Conclusion : Our results suggest that the people with ID are more likely to suffer psychiatric comorbidities than those without ID.
반도체 산업에서 생산용량을 고려한 오더-로트 페깅기반의 납기약속 방법의 정합성 향상에 대한 연구
서정철(Jeong Cheol Seo),방준영(June Young Bang) 한국산업경영시스템학회 2014 한국산업경영시스템학회지 Vol.37 No.4
This paper addresses order-lot pegging issues in the supply chain of a semiconductor business. In such a semiconductor business (memory or system LSI) order-lot pegging issues are critical to achieving the goal of ATP (Available to Promise) and on-time production and delivery. However existing pegging system and researches do not consider capacity limit on bottleneck steps. This paper presents an order-lot pegging algorithm for assigning a lot to an order considering quality constraints of each lot and capacity of bottleneck steps along the entire FAB. As a result, a quick and accurate response can be provided to customer order enquiries and pegged lot lists for each promised orders can be shown transparently and short or late orders can be detected before fixing the order.

Hemorrhagic cystitis is potentially life-threatening sequellae of chemotherapy using oxazaphosphorine alkylating agents (cyclophosphamide and ifosfamide). Mesna contains a sulfhydryl group that is believed to bind acrolein within the urinary collecting system and reduce the hemorrhagic cystitis without affecting the chemotherapeutic potential. To date, about thirty cases of hypersensitivity or allergic reactions of the delayed and urticarial type associated with mesna have been reported. We reported two patients with systemic lupus erythematosus who developed facial rash and flushing associated with mesna which imitate malar rash.

Detached Eddy Simulation (DES) is performed for developing turbulent flow of the 270° curved duct at a Reynolds number of 56,690. The curvature ratio on the basis of a centric radius Rc and a duct height H is 3.357. Turbulence models adopted are k-ω model for Reynolds Average Navier-Stokes (RANS) equation Simulation and Shear Stress Transport (SST) model for DES. DES is used as the hybrid computation technique combined with RANS-SST and Large Eddy Simulation (LES). Predicted results are compared with measured results including the distributions of Reynolds stresses and the flow characteristics on the symmetric plane of curved duct are presented. Judging from the comparison between the predicted and the measured results, the DES approach is applicable to calculate the developing turbulent flow in a 270° curved duct.

우리나라의 재해구호 행정은 "재해구호법"에 의거 자연재해로 인한 이재민 구호 위주로 되어있다. 따라서, 저출산 고령화, 다문화, 기후변화 등 사회 경제 환경적 변화와 함께 신종 복합재난의 빈발할 가능성이 상존해 있으므로 모든 재해에 대처할 통합구호의 필요성이 증대되고 있다. 이와 함께 고령자, 외국인수의 증가로 인해 재해약자를 배려할 법 제도적인 정비는 시급히 해결되어야 할 과제이다. 그리고 구호금과 관련 재난지원금의 신속한 지원을 위한 제도상의 문제점, 재해구호기금과 재해의연금 활성화 등 재해구호재원과 관련된 해결해야 할 과제, 재해구호세트 중심의 경직된 재해구호물자 관리, 임시주거시설의 문제점, 구호교육 훈련 부족, 구호전문가 양성 소홀과 연구개발(R&D)의 저조, 자원봉사 활동의 문제와 관련된 재해구호 운영상의 한계 등으로 인해 구호서비스의 발전전략 마련이 시급한 실정이다. 그리하여 본 논문은 재해구호서비스 증진을 위한 법과 제도, 구호재원과 구호물자, 그리고 구호운영 실태 등을 조사 분석하고 문제를 도출하여 구호업무 발전방안을 제시하고자 한다.

Background and Purpose : Though there were many clinical studies of acupuncture effects they didn't have appropriate control group. So we didn't say it was true acupuncture effect, though subjects in clinical study improved. To investigate the possibility of sham acupuncture application, we examined how well subjects distinguished real acupuncture from sham acupuncture. Methods : We investigate the possibility of sham acupuncture application as the following 3 kinds of methods. 1. The public (n=60) and Oriental Medicine Doctors (n=20) looked at the appearance of acupuncture and then were treated with randomly allocated acupuncture and judged it as real or sham. 2. The public (n=60) and Oriental Medicine doctors (n=20) were treated with randomly allocated acupuncture, then they looked at the appearance of acupuncture and judged it as real or sham. 3. The public (n=60) were treated with randomly allocated acupuncture (right-real-left-sham), (right-sham-left-real), (left-real-right-sham), (left-sham-right-real), then they judged it as real or sham. Results : 1. When the public (n=60) looked at the acupuncture appearance, the correct judgement ratio was 63.3%. After they were treated with acupuncture, the correct judgement ratio was 50.0%. 2. When Oriental Medicine doctors (n=20) looked at the acupuncture appearance, the correct judgement ratio was 25.0%. After they were treated with acupuncture, the correct judgement ratio was 45.0%. 3. When the public (n=60) were treated with acupuncture, the correct judgement ratio was 50.0%. After they looked at the acupuncture appearance, the correct judgement ratio was 63.3%. 4. When Oriental Medicine doctors (n=20) were treated with acupuncture, the correct judgement ratio was 65.5%. After they looked at the acupuncture appearance, the correct judgement ratio was 65.0%. 5. After the public (n=60) were treated with randomly allocated sham or real acupuncture as (right-real-left-sham), (right-sham-left-real), (left-real-right-sham), or (left-sham-right-real). the correct judgement ratio was 66.7% in looking at the acupuncture appearance group, and in not looking at 60.0%. Conclusion : These results indicated that Kim Sham Acupuncture could apply to the double blind clinical study of acupuncture effect. And more continuous studies are needed on Sham Acupuncture apparatus.
