Objectives: This study aims to identify the factors associated with regular medical services utilization of chronic disease patients. Methods: The research selected 4,489 adults aged over 30, diagnosed with hypertension, diabetes, hyperlipidemia, hypercholesterolemia, from the Korea health panel. We analyzed states of regular medical service utilization using descriptive statistics. Multiple regression analysis was used to examine the main factors associated with regular medical services utilization in chronic disease patients. Results: In terms of socio-demographic factors, gender, age, marital status, education level, employment, household income and disability were significantly different between hypertension, diabetes, hyperlipidemia and hypercholesterolemia. Among health status and behavioral factors, number of chronic diseases, subjective health status, smoking, high risk drinking, regular meals, physical activity, obesity were significantly different. From the multiple logistic regression analysis, age, number of chronic diseases, obesity, type of chronic diseases were associated with regular medical services utilization. Conclusions: It is necessary to develop effective health education programs and individualized approach to improve continuous management in chronic diseases patients.

Objectives : This study aims to : (i) characterize and differentiate between two different periods of baby boomers, (ii) study the utilization of their health care services, and (iii) establish effective ways of providing better health service utilization and preventive policy strategies for upcoming and older generations. Methods : A multiple regression analysis using descriptive statistics, frequency analysis, and dummy variables was utilized to access the presence of correlations between socio-demographic factors and health care service utilization. Results : Medical insurance type, marital status, and chronic disease were factors that influenced health care service utilization. Furthermore, the factors that influenced individual medical expenses were cohabitation, inpatient days, and chronic disease. Conclusions : Primary findings and exploratory statistics revealed that there were strong correlations and interaction among some of the predictor variables. Because of the chronologically limited nature of the sample data set gathered in 2012, it would be helpful to continue to develop or research related constructs that may capture relationships more effectively among extended populations.

Improving spectrum utilization efficiency is a fundamental goal of dynamic spectrum access technology. The definition of spectrum holes determines how to detect and exploit them. Current definitions of spectrum holes are ineffective in exploiting spatial-temporal spectrum holes. In this paper, a novel definition of spectrum holes is proposed, in which throughput loss indicates the impact of secondary users on primary users. The definition specifies spectrum holes, unifies the impact of secondary users on primary users and is effective exploiting spatial-temporal spectrum holes. Theoretical analysis and numerical simulations show that the new definition proposed in this paper significantly improves the spectrum utilization efficiency.

Cloud computing has drastically reduced the price of computing resources through the use of virtualized resources that are shared among users. However, the established large cloud data centers have a large carbon footprint owing to their excessive power consumption. Inefficiency in resource utilization and power consumption results in the low fiscal gain of service providers. Therefore, data centers should adopt an effective resource-management approach. In this paper, we present a novel load-balancing framework with the objective of minimizing the operational cost of data centers through improved resource utilization. The framework utilizes a modified genetic algorithm for realizing the optimal allocation of virtual machines (VMs) over physical machines. The experimental results demonstrate that the proposed framework improves the resource utilization by up to 45.21%, 84.49%, 119.93%, and 113.96% over a recent and three other standard heuristics-based VM placement approaches.

Objective This study aims to understand the actual utilization of the oriental rehabilitation medicine center of the initial interdisciplinary medical care at the National Rehabilitation Center and to arrange proper development plans for more effective interdisciplinary medical services for future activation of interdisciplinary medical care. Method: The interdisciplinary patient status, composition of patient care, and major disease-related status were studied and analyzed for oriental rehabilitation medication relating to interdisciplinary medical care at the National Rehabilitation Center. Furthermore, the interdisciplinary status and its operating conditions were evaluated to devise a development plan for the National Rehabilitation Center. Results: As a result of the analysis of oriental rehabilitation medical care diagnosing status utilization at the National Rehabilitation Center regarding interdisciplinary medical care, the ratio of the number of those receiving interdisciplinary oriental rehabilitation medical care was less than half of the total receiving interdisciplinary care. As the major disease status from the patients of interdisciplinary care, stroke patients covered the large majority, and musculoskeletal pain patients covered the majority of outpatients. The establishment of additional oriental medication departments and assigning of interdisciplinary coordinators were presented as the goals of a development plan for the manpower and structural side of interdisciplinary medical care at the National Rehabilitation Center. On the institutional and systematic side, improvement in the interdisciplinary hierarchy and interdisciplinary model development based on the number of patients per disease was proposed. In addition, operation on ward bedding and construction of interdisciplinary EMR medical care is necessary on the medical and administration service side. Conclusion: To understand the actual utilization and to arrange development plans aimed at constructing a safe and effective interdisciplinary hierarchy for interdisciplinary medical care at the National Rehabilitation Center, patient-centered care needs to be implemented.

온실 토양으로부터 주요 작물 병원균의 생육을 억제하는 길항곰팡이를 분리, 동정하였고, 그 균이 분비하는 향균물질을 분리하여 활성을 petriplate assay로 검정했다. 길항균의 foot cell, 분생포자 및 MY20 배지상의 균사 등 형태학적 특징에 근거하여 이 균을 Aspergillus terreus로 동정하였다. A. terreus의 배양여액을 chloroform으로 추출하고, 그 추출물을 column chromatography와 thin layer chromatography로 향균물질을 순수분리하였으며, 화학구조는 butyrolactone I이었다. 이 물질의 주요 작물병원균에 대한 $ED_{50}$은 Botrytis cinerea, Phytophthora capsici. Pythium ultimum, Rhizoctonia solani, 그리고 Fusarium oxysporum에 각각 9.7, 42.6, 23.3, 13.7, 102.7 ppm으로 나타났다.

본 연구의 목적은 노인들의 응급의료이용에 영향을 주는 요인들을 알아보고 의료접근의 형평성을 조사하는 데 있다. 2014년 한국의료패널조사 자료를 사용하여 기술분석과 로지스틱회귀분석이 행하여졌으며 인터뷰에 참여했던 1,313명의 노인들이 표본으로 선정되었다. 연령, 성별, 교육수준 등의 인구변수들이 응급의료이용의 중요한 결정요인이었다. 의료요구는 노인 계층 간 응급의료이용의 차이를 충분히 설명하지 못한 걸로 나타났으나 건강상태는 응급의료서비스를 사용하는 노인들의 중요한 결정요인이었다. 의료비지출은 응급의료서비스이용의 계층 간 차이를 개선하지 못했으나 응급의료이용의 중요한 예측요인으로 남았다. 한국에서 의료개혁은 의료요구를 가진 노인들이 효과적인 진료혜택을 받을 수 있도록 전국민 응급의료 보장을 확대하는 방향으로 계속 이루어져야 한다. 앞으로 연구도 75세 이상의 교령노인과 여성 및 교육수준이 낮은 노인, 그리고 높은 의료비 지출을 하는 노인과 같은 인구계층들에게 혹시 있으지 모르는 의료접근의 장애들을 허무는 방향으로 이루어질 필요가 있다.

충남도내 18개 도서지역의 의료 이용행태와 의료이용을 결정하는 요인을 알아보기 위해 2002년 9월 9일부터 9월 18일까지 조사한 결과는 다음과 같다. 조사대상자의 외래 의료이용 횟수는 연령이 높을수록, 교육수준이 낮을수록 많았고 주관적 건강상태가 나쁠수록 의료이용 횟수가 높았고 통계적으로 유의하였다(p<0.05). 유병 만성질환수가 많을수록 외래 의료이용이 많았고, 의료기관 접근시간이 2시간이상 3시간 미만인 군에서 외래 의료이용 횟수가 높게 나타났다(p<0.05). 의료기관 입원 횟수는 상용치료원이 종합병원인 군에서 가장 높게 나타났고 통계적으로 유의하였다(p<0.05). 의료기관의 입원 횟수에 영향용 미치는 변수로는 주관적 건강상태로 나타났으나(p<0.05) 그 설명력이 미약하였다.
