Today, Software as a Service(SaaS) is being recognized as a key means to enable the innovation of software distribution. Despite the increase in the interest in SaaS, individuals as well as businesses are not yet making an extensive use of it. This research is aimed at identifying and analyzing the antecedents of intentions to use SaaS. We proposed a research model to predict an individual's intention to use SaaS based on the Technology Acceptance Model(TAM). To this end, we conducted a questionnaire survey in which actual software users participated. An empirical analysis has been performed to test the reliability and validity and the hypotheses using SPSS and AMOS software packages. The results of the analysis revealed that functionality, interoperability and economic benefits have positive effects on the intention to use SaaS, while system quality has no significant effect on the behavioral intention. We discussed practical as well as academic implications, and provided research directions.

Readmission which reflects capacity to manage patients and general level of medical services has been known for one of the causes of medical expenditure due to inefficient service. Compared to disease-specific readmission, hospital wide readmission (HWR) is relatively easy to understand, and has merit to get over limitation of collateral medical services assessment; therefore, a growing interest in development and usage of readmission indicator as quality of care indicator focusing on all-disease is detected. In this study, we investigate current state of risk standardized readmission rate indicator used in the United States, the United Kingdom, and Canada, and examine the considerations when using readmission rate as quality indicator in Korea. Differences in risk-adjustment methods were showed among countries. The United States do not control race not to hide socio-demographic factors on readmission. Canada shows differentiation compared to other countries about reflecting community factors. All three-countries utilize readmission rate as monitoring quality of care rather than incentives or penalty due to the fact that readmission rate could not represent the whole quality of hospital and has a limitation at controlling socio-economic factors. Therefore, for usage readmission rate as quality indicator in Korea, preparing readmission classification standard for Korean medical environment and additional methods for acquiring information by using discharge summary is need. Moreover, continued discussion with clinical specialists is needed for obtain clinical reliability and validity.

Busan Port which is the representative social overhead capital facilities for international trade of goods has been the driving force for economic development in Korea. Therefore, the central government should play the major role in building a rear road to Busan Port in order that it may function as a mojor port of Northeastern Asia through the systemization of mutual assistance among connected facilities, completely equipped with port-related facilities befitting to the principal port of imports and exports. In this study, the validity of container tax is being examined, analyzing container tax which Is considered as an obstacle to the development of Busan Port and its purpose, and grasping the present conditions by the realistic speculation on container tax issues and its abolition. First, the port rear road as a social overhead capital facilities, which connects port and expressway, should be considered as part of port, and port is social overhead capital invested by government. Second, the susan City imposes on container tax. As a result, a shipper and a shipping company are paying a double charge by paying container tax with port dues. Third, someone argues that port rear road is constructed as container truck generates much traffic, but it is unreasonable to conclude that container truck is seed of traffic jam because according to traffic survey of Busan City, container truck occupies only 1.45% of total traffic Forth, it has bad influence upon the competitiveness of Busan Port as Northeastern logistics base, as other ports who are competing with Busan Port like Singapore. Hong kong, Kobe make their competitiveness strong by decreasing the cost of pore dues

Nursing education in Korea has made rapid progress recently. There is .: great deal of support with approval and encouragement of this progress. However, much disapproval of its validity has asserted some restraints on it. The aims of nursing education should be based on the principle that education is planned according to tile need much research has been made with such a viewpoint but much still remains unclear. The present study is aimed at establishing the needs for nursing manpower based on the biological demand for medical care. The needs for nursing manpower have been emphasized by many researchers and authorities on nursing education, and the prevailing medical trends also demand it. In this study, through the study of various hooks and records concerned, and the compiling of data analysis and questionnaires, I came to the following figures for the proposed needs of nursing manpower: There figures are greater than those calculated by another method by the government research program but it shows approximately the same final figure as that of the government report for the end of the target year. With these findings, I concluded that: 1) As the final purpose of the government medical project is to fulfill the needs of the national health (that is, to support the national needs for medical care), the plan of this project should follow the theory of biological demand for medical care, recognizing that the numbers will increase gradually. 2) Qualitative growth, based on the advanced and specialized nursing profession. should be promoted to meet the rapid growth of the medical needs of the nation in addition to promoting of investments for the facilities. and of the preparatory investments for education needs. 3) For efficient and economic utilization of nursing manpower, the improvement of wages, and the offering of free education is necessary. 4) Amendments to the low promising innovation and advancement of medical treatment; preparation of a national fund for medical care; and, changing of national attitudes to bring about greater concern are desirable.

Since natural disaster occurs increasingly and becomes complicated, it causes deaths, disappearances, and damage to property. As a result, there is a growing interest in the development of ICT-based natural disaster response technology which can minimize economic and social losses. In this letter, we introduce the main functions of the forest fire management platform by using images from an UAV. In addition, we propose a disaster image analysis technology based on the deep learning which is a key element technology for disaster detection. The proposed deep learning based disaster image analysis learns repeatedly generated images from the past, then it is possible to detect the disaster situation of forest-fire similar to a person. The validity of the proposed method is verified through the experimental performance of the proposed disaster image analysis technique.

The purpose of this study was to analyze the relationship between the locational characteristics of areas surrounding oriental medicine hospitals and the number of patients who visited study hospitals. Administrative data collected from the annual report of 5 ward offices in Daejeon used to assess the geographical attributes. Two oriental medicine hospitals operated in Daejeon provided data for the number of inpatient and outpatient. Number of patients who visited study hospitals was calculated in each Dong which is the smallest administrative district. The geographical attributes of Daejeon were evaluated by the demographic and economic factors which were assumed to influence the health care demand. Each criterion was measured from each Dong. Weights of factors was calculated by Analytic Hierarchy Process (AHP) method. Evaluation scores which representing the geographical attributes of Dong was computed by multiplying the eight factors and weights. Results showed positive correlation coefficients between the evaluation scores of Dong and the number of patients. One hospital which was more closely located to areas with high evaluation scores had higher number of patients than that of the other hospital. Buffering analysis with varying size support the analysis results. This finding proposed the importance of location for the management of oriental medicine hospitals in a metropolitan city. Applying study model to other cities will enhance the validity of study results.

The CFT (Concrete Filled Steel Tube) columns became popular in high rise building construction due to not only its composite effect but also economic advantage. However, it has been pointed out in various previous researches that the current practice in CFT columns may lead the steel tube to probable local buckling at critical sections of the columns right after yielding. To resolve such a problem, the TR-CFT (Transversely Reinforced Concrete Filled Steel Tube) column is proposed to control or at least delay the local buckling state at the critical section by wrapping the CFT columns with carbon fiber sheet. The validity of the proposed column system is validated through the present paper by observing the experimental performance and comparing it with the analytical prediction of the TR-CFT columns with hish strength concrete. It is also shown that the current design code provisions such as ACI-318, in which the contribution of concrete confining effect filled in steel tube is not appropriately accounted for, may contain too much conservatism.
