Recently we can see many cases that the CRM Systems are implemented and operated in Hospitals. The reason for such situation is the management environments in medical service market is changing rapidly one hand, and on the other hand the competitions among the Hospitals became more severe. In this paper we try to present the factors and weights as index for the measurement of Hospital CRM's System Performance. To achieve this goal, we derived the primary factors for the success of the CRM Systems based on the precedent researches, and futhermore carry out the verification of the rightness of those factors. For the verification of the rightness of the factors, we employ the Structured-Model-Analysis Method of AMOS. This enhance the meaning of the analysis result of the factors. And we use the AHP method to compare the importance grade of each success factors, because the comparison of importance level of each success factor is very crucial for the measurement of the Hospital CRM's system performance. As a result, we derived the primary factors and analyzed the weights in this paper, which might be used as the guiding Index for the measurement of the Hospital CRM' System Performance.

물수지의 불균형으로 발생되는 가뭄은 장기간에 걸쳐 넓은 규모로 발생되는 자연재해로서, 농업 및 산업에 직접 피해와 다양한 상품에 대한 공급 부족으로 인한 가격 상승 등의 간접 피해를 야기하는 재해이다. 이러한 가뭄을 정량적으로 평가하기 위하여 기상 요인(강수, 기온), 농업 요인(식생), 수문 요인(증발산, 토양수분) 등과 같은 설명 변수를 기초로 하는 많은 가뭄지수들이 개발되어 왔다. 대표적인 가뭄지수에는 Standardized Precipitation Index (SPI), Standardized Precipitation Evapotranspiration Index (SPEI), Palmer Drought Severity Index (PDSI), Soil Water Deficit Index (SWDI), Vegetation condition index (VCI), Temperature Condition Index (TCI), Vegetation Health Index (VHI), Scaled Drought Condition Index (SDCI), Integrated Crop Drought Index (ICDI) 등이 있다. 본 연구는 최근 개발된 통합작물가뭄지수(ICDI)를 통해 미국 옥수수의 약 90%를 생산하는 농업지역인 미국 콘벨트의 가뭄 특성을 분석하고자 한다. ICDI는 기상 요인(강우량 및 지표면 온도), 수문학적 요인(잠재 증발산 및 토양수분), 식생 요인(강화식생지수(Enhanced Vegetation Index, EVI))의 조합을 통해 지표면의 건조·습윤 상태 및 식생의 건강 상태를 설명하는 가뭄지수이다. 2004년부터 2019년까지 주요 콘벨트 지역인 일리노이, 인디애나, 아이오와를 대상으로 가뭄분석을 실시하였으며, 옥수수 수확량 아노말리와의 상관성을 분석하였다.

The loading test of wind turbine pitch and yaw bearings have been conducted using special test rig designed for the test of large slewing bearings. Test type was fatigue test that applied fatigue load to each bearing and followed the defined test process. Measurement data during test were rotational torque and raceway temperature, and inspected key components by disassembling the bearing after all test finished. As a results, the raceway temperature during test did not exceed the operational temperature range of lubricant and rotational torque was reduced as the bearing's rotational cycle increased. In the inspection of key components, some plastic deformation and flaking were detected at some raceway sections while other components such as ball, spacer and seal remain indefective conditions.

Objectives：Present study developed the computerized ADHD Diagnostic System(ADS) in order to diagnose ADHD and evaluate treatment effect of it, and conducted a standardization study for ADS. Methods：The normative group was composed of 847 children and adolescents between the age of 5 and 15(boy 429, girl 418) living in the areas of Seoul, Kyunggi-do, and Kangwon-do. 30 ADHD children with age ranged 7 to 9 years were participated present study to evaluate the validity of ADS. To establish the norms for diagnosing ADHD, the means and standard deviations of normative group were used to calculate T-scores for each age group. Results：The reliability coefficient of ADS(Cronbach's ${\alpha}$) was .85. There were significant differences in the measures of ADS except commission error between the normal and the ADHD groups. Three factors were extracted through factor analysis of ADS, which were labelled 'inattention', 'slow information processing' and 'impulsivity'. Discriminant analysis showed that ADS significantly discriminate the normal and the ADHD groups. Percentage of correct classification by ADS variables was 96.7%. Conclusion：These results put together strongly support the reliability and validity of ADS as a diagnostic instrument for ADHD.

Large-scaled hospital information system projects are often delayed than originally planned. Regarding project management, it is necessary to examine main factors triggering the schedule delay and to analyze the causality of such delay. This study tries to find the delay factors and causal relationship between them based on the case of the hospital information system development project by using the grounded theory method. It turned out that 'unrealistic scheduling' affects overall schedule delays like domino phenomenon, and 'poor analysis of existing systems' leads to poor quality of work analysis while 'poor subsystem integrated interface' triggers poor design quality. This study found out the factors affecting the delay of a project, analyzing cause-and-effect relationships between them in the academic side. From the practical view, it shows a solution to minimize delays in the project schedule for each of SI companies, hospitals and project managers.

With constant relaxation of regulations by the government in the 4th industrial innovation era, it has brought huge changes to the education environment as it has created solutions to hindrance factors against introduction of the cloud. Universities are getting more interested in the introduction of the cloud Computing but they still remain at the level of recognition diffusion and creating ambience. The study has analyzed empirical factors of the effect of introduction of the successful case "K Cyber University's Construction of Cloud-Based Remote Education System" through the previous studies on trait factors affecting the introduction of the cloud computing and the analysis of factors in terms of expandability, agility, compatibility, economic feasibility, security, stability and institutional support. Factors drawn through this are meaningful for empirical studies on presenting strategies and the directivity to introduce the cloud computing successfully. This study can be used as the background for further studies which will require various factors prior to introducing the cloud computing.

Recently, the mobile game industry is explosively extending and advancing. Nevertheless, although research on IT acceptance has been actively performed, the effective studies have not been accomplished in the acceptance of mobile game. This study, therefore, explores the factors affecting customer's intention to use mobile game. Five external factors(service quality, social influence, instant connectivity, self-innovativeness, and self-efficacy) are proposed to test the several hypotheses. The factors are classified to three dimensions - system, individual, and society. The research model is based on various studies on TAM(Technology Acceptance Model) and mobile service. A survey of mobile game users collected 270 cases, and we used 261 cases for statistical analyses. The analyses show that service quality, instant connectivity, self-innovativeness, and self-efficacy have an indirect effect on the intention to use through perceived usefulness and perceived ease of use. We provide the important factors that should be focused on when an enterprise develops and promotes new mobile game products.
