김준영,김혜영(Kim, Joon-young,Kim, Hye-Young) 한국복지행정학회 2012 복지행정논총 Vol.22 No.2

본 연구는 우리나라 16개 광역시·도의 사회통합의 수준을 측정하기 위한 사회통합 지표를 구성하고, 지역 간의 사화통합 수준의 차이를 살펴본 연구로서, 우리나라 실정에 맞게 학계, 공무원 등 전문가들의 협의를 거쳐 사회통합 지표를 구성하였다. 사회통합 영역과 관련된 개별 사회통합 지표들은 지표의 이용가능성, 계량화 가능성, 객관성을 고려하여 통계청의 국가정보통계포털을 자료를 활용하였고, 16개 광역시도별 분석이 가능한 사회통합 지표를 분석하였다. 주요 연구결과를 살펴보면, 전반적으로 대도시 지역이 다른 지역에 비해 상대적으로 사회통합 수준이 낮은 것으로 나타났다. 또 우리나라 시도별 사회통합 양상의 특징은 대부분의 광역시도들의 사회통합 수준은 각 영역별로 일치된 방향으로 나타나는 것이 아니라 각 사회통합 영역별로 상반된 점수를 보여주는 것으로 나타났다. 이는 전체적으로 모든 영역에서 뚜렷하게 높거나 낮은 사회통합 수준을 보여주는 광역시도는 없고, 어느 한 영역에서 높은 통합수준을 보이면 다른 영역에서는 낮은 통합 순위의 경향을 보이는 것으로 나타났다. 본 연구결과를 토대로 지역별 사회통합의 실태를 파악하고, 사회통합 수준의 차이를 살펴봄으로써 지역별 상이한 현안과제를 도출하고, 지역 현안과제를 해결하기 위한 사회정책의 개발 및 추진 방향을 이끌어 낼 수 있는 기초적인 정보를 제공하였다는 점에서 의의가 있다. The purpose of this study was to work out a social cohesion index to measure the level of social cohesion of 16 metropolitan cities and provinces and then examine the regional difference of social cohesion. The social cohesion index was worked out through consulting with experts in academic circles and public servants, in consideration of domestic circumstances. As for the individual social cohesion indices, which were related to the areas of social cohesion, National Statistical Office’s portal for national information statistics was used as data by taking the usability, quantifiability and objectivity of indices into account, and such social cohesion indices that were possible to be examined by 16 metropolitan cities and provinces were analyzed. Study findings are as follows: Megacity’s social cohesion level was lower than that of other areas in general. In addition, the characteristic of domestic social cohesion modality of metropolitan cities and provinces was that the social cohesion level of metropolitan cities and provinces seemed to proceed not to corresponding directions by areas but show conflicting scores by social cohesion areas. In other words, there was no metropolitan city or province of which level of social cohesion was distinctively high or distinctively low in all the areas. When one area’s social cohesion level was high, that of other areas seemed to be low. This study is seemingly meaningful in that via examining the current status of regional social cohesion and the difference of social cohesion level, study findings could provide basic information on working out the strategy of developing and implementing social policies, in order to find out and settle regionally different urgent problems.

Purpose: The purpose of this study was to assess the diagnostic accuracy of various quantitation methods using F-18-fluorodeoxyglucose (FDG) in patients with malignant or benign lung lesion. Materials and Methods: 22 patients (13 malignant including 5 bronchoalverolar cell cancer; 9 benign lesions including 1 hamartoma and 8 active inflammation) were studied after overnight fasting. We performed dynamic PET imaging for 56 min after injection of 370 MBq (10 mCi) of FDG. Standardized uptake values normalized to patients body weight and plasma glucose concentration (SUVglu) were calculated. The uptake rate constant of FDG and glucose metabolic rate were quantified using Patlak graphical analysis (Kpat and Mrpat), three compartment-five parameter model (K5p, MR5p), and six parameter model taking into account heterogeneity of tumor tissue (K6p, MR6p), Areas under receiver operating charac-teristic curves (ROC) were calculated for each method. Results: There was no significant difference of rate constant or glucose metabolic rate measured by various quantitation methods between malignant and benign lesions. The area under ROC curve were 0.73 for SUVglu, 0.66 for Kpat, 0.77 for Mrpat, 0.71 for KSp, 0.73 for MRSp, 0.70 for K6p, and 0.78 for MR6p, No significant difference of area under the ROC curve between these rne- thods v;as observed except the area between Kpat vs. Mrpat (p<0.05). Conclusion: Quan- titative methods did not improve diagnostic accuracy in comparison with nonkinetic methods. However, the clinical utility of these methods needs to be evaluated further in patients with low pretest likelihood of active inflammation or bronchoalveolar cell carcinoma.

목적: 주의력결핍 과잉운동장애(ADHD)는 소아에서 3-5%의 유병률을 보이며 전두엽의 억제기전 저하와 대뇌의 카테콜라민 대사이상이 관련된다고 알려져 있다. ADHD 환아에서 야뇨증을 비롯한 다양한 하부요로계 증상을 동반한다는 보고가 있지만 국내에서는 ADHD 환아들에 대한 보고가 없기에 저자들은 ADHD 환아에서 배뇨증상을 알아보기 위해 본 연구를 시행하였다. 방법: 2009년 10월부터 2011년 3월까지 DSM-IV 진단기준에 근거하여 ADHD로 진단받은 33명의 환아들과 같은 기간 동안 신경계 질환이나 요로계 질환 없이 상기도 감염으로 외래를 내원한 환아 30명을 대상으로 배뇨와 배변에 대한 설문지를 시행하였다. 결과: ADHD 환자군의 평균 연령은 $9.09{\pm}2.8$세(남 28: 여 5) 이었고, 대조군의 평균 연령은 $8.58{\pm}3.1$ (남 20: 여 10) 이었다. ADHD 환아군에서 대조군에 비해 요절박(P=0.017), 절박 요실금(P=0.033), 변비(P=0.045)의 유병률이 대조군에 비해 유의하게 높았고, 복압배뇨, 간헐뇨, 배뇨지연 행동에는 두 군간에 유의한 차이가 없었다. 야뇨증은 ADHD 환아군에서 12.1% (4/33)로 대조군의 0%에 비해 많았지만 통계학적인 유의성은 없었다. 결론: ADHD 환아는 대조군에 비해 요절박, 절박 요실금과 변비의 유병률이 유의하게 높았다. Purpose: Attention deficit hyperactivity disorder (ADHD) has been associated with impairments in frontal inhibitory function and the catecholaminergic system. ADHD is diagnosed in 3-5% of children. Children with ADHD seem develop various forms of urinary problems such as nocturnal enuresis, dysfunctional voiding, and diurnal incontinence. However, no data exist to confirm the presence of these problems in Korean children with ADHD. We investigated the clinical findings of voiding dysfunction in children with ADHD. Methods: Between October 2009 and March 2011, a total of 63 children (33 with ADHD, 30 with an upper respiratory infection, as a control group) were enrolled. ADHD was diagnosed using the diagnostic and statistical manual of mental disorders (DSM)-IV criteria. A comprehensive survey of voiding and defecation was administered. Results: The patient group included 28 boys and 5 girls; the control group comprised 20 boys and 10 girls. The mean age was $9.09{\pm}2.8$ years in the ADHD group and $8.58{\pm}3.1$ years in the control group. Children with ADHD had a statistically significantly higher incidence of urgency (P =0.017), urge incontinence (P =0.033), and constipation (P =0.045). There was no significant difference in the incidence of straining, intermittency, holding maneuvers, or nocturnal enuresis. Conclusion: Children with ADHD in Korea have significantly higher rates of urgency, urge incontinence, and constipation than those without ADHD.

Steam Reforming H2 Generation (SRH2G) System is a chemical process to produce hydrogen through steam reforming of hydrocarbon. Largely speaking, there are two types of materials for the SRH2G: 1) Oil and coal, and 2)Natural Gas such as shale gas. From the perspective of cost, quality (purity), and environmental burden (pollution), the latter is much more desirable than the former. For this reason, research on SRH2G using natural gas is actively carried out, and implemented and operated in the various industry. In this paper, we develop a natural gas based SRH2G system via systems engineering approach. Specifically, we first derived stakeholder requirements, followed by systems requirements and finally system architecture via a tailored SE process for plant (called Plant Systems Engineering (PSE) process) based on ISO/IEC 15288. The developed method was applied to iron and steel plant as a case study. Through the case study, by the SE approach, we were convinced that a successful system satisfying stakeholders' requirements within the given constraints can be developed, verified and validated.

In the energy-guzzling industries such as steel making and cement, power plants utilizing waste heat have been attracting attention to increase energy efficiency. However, the existing economic analysis system doesn't consider the special working fluids and the cost models of the main equipment used in the waste heat recovery power plant. So it is difficult to estimate the plant economics accurately. Therefore, It is required to develop a economic analysis module that can more accurately evaluate for the power plant. In this study, the systems engineering approach was used to design and develop the module that systematically reflects the characteristics of the power plant and various requirements. Specifically, first, the special working fluids and main equipment applied to the power plant were investigated. Next, the cost models for each equipment were developed. Finally, the economic analysis module based on this was developed.

Dengue fever (DF) is endemic throughout tropical and subtropical regions; however, it is not endemic in Korea. Imported infectious diseases should be suspected when encountering returned travelers with non-specific symptoms such as fever, rash, and headache. Persistent vomiting, abdominal pain, hemorrhagic tendency, hepatic enzyme abnormalities, and proteinuria are risk factors for the development of severe DF in a patient with DF. Severe hyperglycemia is also known to be related to poor prognosis in acute illness, and with certain underlying diseases that present with hyperglycemia, such as diabetes, it is related to the progression of severe DF. We report a DF case with severe hyperglycemia in an adolescent returning from India. Pediatric DF cases reported in Korea were also reviewed.
