The present study applies the TAM (Technology Acceptance Model) to investigate the factors that affect the intention to use the mobile payment services. For this purpose five potential variables (perceived usefulness, perceived convenience, ubiquity, innovativeness, and safety risk) that are expected to affect the intention to use the mobile payment services were selected. An online survey was administered, and 339 questionnaires were analyzed. Structure Equation Model (SEM) Analysis revealed that TAM variables (perceived usefulness and perceived convenience) partially influenced the attitude. The perceived usefulness predicted the attitude while perceived convenience did not predict the attitude toward the mobile payment service. Personal characteristics variable (innovativeness) and mobile nature variables (ubiquity, and security risk) were identified as the predictors of the attitude toward the mobile payment service. While innovativeness and ubiquity affected the attitude positively, security risk affected the attitude negatively. Finally, the analysis substantiated the influence of attitude toward the mobile payment services on the intention to use the services. On the basis of findings, managerial implications and suggestions for further studies were discussed.

With the explosive rapid expansion of computer using during the past few years, security has become a crucial issue for modem computer systems. Today, there are many intrusion detection systems (IDS) on the Internet. A variety of intrusion detection techniques and tools exist in the computer security community such as enterprise security management system (ESM) and system integrity checking tools. However, there is a potential problem involved with intrusion detection systems that are installed locally on the machines to be monitored. If the system being monitored is compromised, it is quite likely that the intruder will after the system logs and the intrusion logs while the intrusion remains undetected. In this project KIT-I, we adopt remote logging server (RLS) mechanism, which is used to backup the log files to the server. Taking into account security, we make use of the function of SSL of Java and certificate authority (CA) based key management. Furthermore, Support Vector Machine (SVM) is applied in our project to detect the intrusion activities.

There are lots of specialized graduate schools such as law school, medical school, business school. These specialized graduate schools has been designed to train the special experts practically from 1990s in Korea. For all that, there are no specialized graduate schools supported by the Small and Medium Business Administration(SMBA). So we will research the establishment plan of SME(Small and Medium Enterprise) specialized school for the development of SMEs. Recently, the SMBA supports the 2 types of graduate school such as the entrepreneurship graduate school and consulting graduate school. However, it is clear that these 2 types of schools are yet insufficient in terms of efficiency and redundancy. As the representative specialized graduate schools are law school and MOT(Management of Technology) in Korea, we do the comparative study with law school and MOT school. Through the comparative study, we can find some implication for SME specialized graduate school. As a result, the SME school has to need the training system such as the special master's and doctor's degree, over 3 year course work, daytime class, many practical professors, specialized programs with industry like the MOT school. In conclusion, we suggest that : First, the SME specialized graduate school has to be designed for potential SME consultants. Second, the entrepreneurship graduate school and the consulting graduate school can be integrated into the SME specialized school easily. Third, the SME specialized graduate school can have new educational models.

Although Changdong Sanggye area has been developed during 1980s as a new city for the supply of low-income housing, currently it was degraded to a bed town located outside Seoul. However, Changdong Sanggye area is designated as the center of a metropolitan area in '2030 Seoul City Basic Plan' due to a variety of potential factors such as a traffic center for linking metropolitan areas, location of 15 universities, and neighboring natural environment like Jungnang stream and Buckhan mountain. The purpose of urban regeneration plan is to create a new CBD of Changdong Sanggye which is the center of vocational and cultural lives of 3.2 million people in the northeastern metropolitan area. To achieve the purpose, 12 unit projects and 24 sub-unit projects are set up based on the three major goals and core strategies. An enterprise project team of northeastern area was newly founded and then a dedicated organization was established by the Seoul government in 2015 in order to integrate separated urban regeneration related functions. In the Seoul government an administrative council and a project promotion council are operated for consultation and coordination between the administrative divisions and government projects for urban regeneration. Through the success in Changdong Sanggye regeneration project, they are expected to have economic effects such as job creation and increase in tax revenue and to re-vitalize the area as a new economic center in northeastern Seoul having amenities and cultural facilities and waterfront parks.

We propose a container orchestration system for process workloads that combines the potential of big data and machine learning technologies to integrate enterprise process-centric workloads. This proposed system analyzes big data generated from industrial automation to identify hidden patterns and build a machine learning prediction model. For each machine learning case, training data is loaded into a data store and preprocessed for model training. In the next step, you can use the training data to select and apply an appropriate model. Then evaluate the model using the following test data: This step is called model construction and can be performed in a deployment framework. Additionally, a visual hierarchy is constructed to display prediction results and facilitate big data analysis. In order to implement parallel computing of PCA in the proposed system, several virtual systems were implemented to build the cluster required for the big data cluster. The implementation for evaluation and analysis built the necessary clusters by creating multiple virtual machines in a big data cluster to implement parallel computation of PCA. The proposed system is modeled as layers of individual components that can be connected together. The advantage of a system is that components can be added, replaced, or reused without affecting the rest of the system.

Calcium metaphosphate (CMP) nanofibers with a diameter of ${\sim}600nm$ were prepared using electrospun CMP/polyvinylpyrrolidone (PVP) fibers through a process of drying for 5 h in air followed by annealing for 1 h at $650^{\circ}C$ in a vacuum. The viscosity of the CMP/PVP precursor containing 0.15 g/ml of PVP was 76 cP. Thermal analysis results revealed that the fibers were crystallized at $569^{\circ}C$. The crystal phase of the as-annealed fiber was determined to be ${\delta}-CMP\;({\delta}-Ca(PO_3)_2)$. However, the morphology of the fibers changed from smooth and uniform (as-spun fibers) to linked-particle characteristics with a tubular form most likely due to the decomposition of the inner PVP matrix. It is expected that this large amount of available surface area has the potential to provide unusually high bioactivity and fast responses in clinical hard tissue applications.

The purpose of this study was. to develop a valid and reliable Likert-type scale to assess middle school students' attitude toward environmental pollution. The evaluation categories of this instrument were cognition and conaction levels. Initially, 42 statements (29 statements for cognition level and 13 statements for conaction level) were framed. This pilot instrument was administered to 1015 middle school students. To select valid and reliable statements, the 42 initial statements were analyzed by item mean, standard deviation, and response distribution. In addition, the emotional intensity: of each statement was judged. As a result, 22 final statements (14 statements for cognition level and 8 statements for conaction level) were developed. Cronbach alpha coefficient of the instrument was 0.76 with a range of item-total correlation from 0.229 to 0.488. Factor analysis was done to explore the potential constructs of this instrument. As a result, six factors were extracted. Those factors were identified as "Conaction to prevent environmental pollution", "Confrontation with the enterprise which causes environmental pollution", "Voluntary inclination to participate in the group which prevents environmental pollution", "Discussion on environmental pollution", "Environmental pollution and interests", and "Everyday sources of environmental pollution".

In a dynamic IT environment, employees often utilize external IT resources to work more efficiently and flexibly. However, the use of external IT resources beyond its control may cause difficulties in the company. This is known as "Shadow IT." In spite of efficiency gains or cost savings, Shadow IT presents problems for companies such as the outflow of enterprise data. To address these problems, appropriate measures are required to maintain a balance between flexibility and control. Therefore, in this study, we developed a new information security management system called AIIMS (Advanced IT service & Information security Management System) and the Shadow IT Evaluation Model. The proposed model reflects a Shadow IT's attributes such as innovativeness, effectiveness, and ripple effect. AIIMS consists of five fields: current analysis; Shadow IT management plans; management process; education and training; and internal audit. There are additional management items and sub-items within these five fields. Using AIIMS, we expect to not only mitigate the potential risks of Shadow IT but also create successful business outcomes. Now is the time to draw to the Light in the Shadow IT.
