To derive a check list of a borrowed city phenomenon, this discussion, through two cities subway OOH advertising in door, compared for convergence by segment analysis. First, discussions considered to be close to the topic of this discussion were arranged and summarized. Seoul and London were selected, and both sides of subway train doors in two cities selected, their states pictured and the images analyzed. As a result of comparison, in case of Seoul subway, the boundary between public information and commercial information(outdoor advertising) was very vague, so the borrowed city phenomenon was very generally analyzed. However, In case of London subway, its result was very contrary to that of Seoul. Eventually, Subway train doors of Seoul city as a borrowed city extracted check points of height, size, color, interval, space and permanency. Therefore in order to study serious discussion this contribution is necessity to limit thoughtless OOH advertising by these checklists in Korean cities.

As the cloud computing law was passed in March, 2015, many private companies and public organizations give consideration to introduce cloud computing services. However, most of them are still concerned about the security issues in cloud computing services. To solve the problem, a certification system of cloud security is necessary as an enabler for adoption of the trusted cloud services. There have been a number of studies about certification systems for cloud security, but only few studies exist about certification scheme of cloud security. Therefore, in this study, foreign certification systems for cloud security are analyzed to draw requirements for developing a domestic certification scheme for cloud security. Based on the result of analysis, this study proposes the three certification schemes of cloud security, which have been reviewed by the focus group interview method to draw advantages and disadvantages of each scheme.

In the process of complex shopping mall development, all the steps (business planning step, pre-sale & completion step, management & operations step) head towards a consistent ultimate goal in an overall business perspective. In this study, we analyze using a structural equation model if an appropriate relations between each of the steps are formed to achieve the ultimate goal. In this study, we find a positive relationship between business planning step and pre-sale & completion step, and also find that for success pre-sale & completion, a faithful business plan is necessary. But we find no statistically significant relationship under significant level 0.05 among business planning step and management & operations step and the level of success, pre-sale & completion step and management & operations step and the level of success, management & operations step and the level of success. This suggests that each of the steps does not form a close relationship to achieve the consistent goal in the complex shopping mall development and each one is doing a short-sighted work for its own profit.

Reviewing the previous researches related to SW quality, we find that they are mostly quality evaluation models for SW quality improvement and maturity-design models for software project management evaluation. There are few studies for the appropriateness of SW quality management by Quality Control(QC) functions. Moreover, they are bound for government's SW R&D projects in the view of the third party. Therefore, we propose means for the objective evaluation of SW quality management's appropriateness by QC functions. For this reason, there are three research proposes in our study as follows. Firstly, we produce problems for the evaluation of the existing government's SW R&D project management's appropriateness. Secondly, to overcome the drawbacks for the evaluation of the appropriateness of SW quality management, new appropriateness evaluation methods are proposed. Lastly, we investigate the availability and effectiveness of the appropriateness evaluation methods for WBS projects.

The container terminals use convergence technology that exchange information for cargo work, using wireless communication between the TOS(Terminal Operations System) and the handling equipments(CC, TC, YT). But if the container cargoes pile up high in the container yard, delayed cargo work and cargo working list information error happen because of communication dead spots(the worker can not receive the information) which wireless communication is disconnected. At this time the driver of the yard tractor(YT) must be able to recognize the communication state. If then, delayed cargo work and cargo working list information errors that occur in the shaded communication area can be avoided, and can process the delayed work due to wireless communication break. In this project, we have built wireless communication environment to increase the efficiency of the loading and unloading operations which the operator can respond actively, when the work is delayed and work orders result in errors. That is, the flow of the wireless communication module has been changed.

This paper proposes an autonomous machine learning method applicable to the BCI(Brain-Computer Interface) is based on the self-organizing Kohonen method, one of the exemplary method of unsupervised learning. In addition we propose control method of learning region and self machine learning rule using an interactive function. The learning region control and machine learning was used to control the side effects caused by interaction function that is based on the self-organizing Kohonen method. After determining the winner neuron, we decided to adjust the connection weights based on the learning rules, and learning region is gradually decreased as the number of learning is increased by the learning. So we proposed the autonomous machine learning to reach to the network equilibrium state by reducing the flow toward the input to weights of output layer neurons.

We investigate how the regional prevalence of hyperlipidemia is affected by health-related and socioeconomic factors with a special emphasis on geographic variations. We focus on the likelihood of hyperlipidemia as function of various region-specific attributes. We analysis a data set at the level of 249 small administrative districts collected from 2012 Korean Community Health Survey by Korea Centers for Disease Control and Prevention. To estimate, we use several methods including correlation analysis, multiple regression and decision tree model. We find that the average prevalence of hyperlipidemia in 249 small districts is 9.6% and its coefficient of variation is 28.3%. Prevalence of hyperlipidemia in continental and capital regions is higher than in southeast coastal regions. Further findings using decision tree model suggest that variations of hyperlipidemia prevalence between regions is more likely to be associated with rate of employee, level of stress, prevalence of hypertension, angina pectoris, and osteoarthritis in their regions.

This paper is about the utilization of public interaction design in terms of design convergence study. As there are different perspectives about public character in various academic fields, it is not simple to define the concept of it. In Korea, since 1960's, the public art which considered only about places has received more and more people's attention. But, there still remain disputes over the residents' participation and communication problems. It is more important to debate mainly on the value judgments of the public design considering artistic experience, ease, functionality, and utility in the interaction rather than a focus on user's experience. On the basis of this, it is suggested bench design which includes flower motif to access and utilize freely to necessary information and the bench design will be helpful to provoke interaction and design convergence in the era of new media technology.

The purpose of this study is to investigate patients with Lou Gehrig's disease, their families, and their actual conditions of the disease, and to find the factors to alleviate caregiving burden and the needs of service. According to the study, the sociodemographic characteristics of the patients with Lou Gehrig's disease and their patients, the disease and caregiving, and activity support service didn't influence alleviation of caregiving burden. When the main caregiver of the patient was not a spouse, or graduated from high school and less, and when the disease was diagnosed initially, there was a difference in caregiving burden. Based on the results, this study suggested that it would be necessary to make medical support suitable to Lou Gehrig's disease and come up with a convergence policy to support personalized and specialized welfare service.
