21st Century is getting into Super aging society worldwide basis. Among those population, silver(aged) generation users' physical condition, such as sight, hearing and body, is getting older, especially sight ability which processes 80% of input data, it requires us studying new smartphone GUI designs convergence for the elderly. In light of this social phenomenon, this study suggests smartphone GUI designs convergence guideline for the silver generation through the research of text, icon which are basic elements of smartphone GUI with proper visual attributes. I had inferred UX designs, expert group and evaluation categories from existing papers, related books and designed some displays for the survey. I also offered this guideline with the deep survey of 101 people over 65 years old.

The purpose of this study is to investigate the necessity of policy approach in terms of complex combination of tourists and fishing villages. In order to achieve the purpose of this study, the policies related to the marine tourism industry were investigated and the laws related to the development of the coastal area and fishing port area were investigated. As a convergence approach to marine tourism policy, First, the development of marine tourism resources should be based on the increase of hydrophilic activities and the characteristics of the four seasons. In particular, the need to dig through support of projects such as the successful model that made aquarium associations etc. that are currently in progress, such as "fishing village experience".

The increase in international logistics market and various customer demands emphasize the importance of Multimodal Transportation, and that market is continuously keep growing. In order to ensure competitive superiority in a market of such infinite competition, service that can satisfy each individual customer by considering various customer characteristics, has become an issue. Thus, through the aspect of service, in order to improve customer satisfaction, growing factors of Multimodal Transportation Route on was studied in this research. For this research, first of all main service factors that affect the growth of Multimodal Transportation were seized by literature survey and positive research. The, by using these factors a methodology that enables individual customers to assess Multimodal Transportation Route was studied. Through this research, individual customers can acquire objective assessment data and Multimodal Transportation companies can seize what factors are considered as important by their customers.

In this study, we investigated the effects of electron beam irradiation on the rheological properties of PLA for enhancing processability. The electron beam was irradiated onto the pure PLA, chemically modified PLA by reactive extrusion, and PLA containing functional monomer. The complex viscosity and log G'vs. log G" plot among dynamic rheological properties were chosen for comparison. The complex viscosity of irradiated pure and chemically modified PLA decreased significantly due to de-gradation of PLA molecules with increasing the E-beam dosages. Complex viscosity of irradiated PLA with functional monomer showed maximum value at moderate dosage, while at high dosage the complex viscosity was decreased by a prolonged irradiation.

The tomb is an important clue for understanding the ancient society of Namwon (南原). In order to establish local identity through the burial mounds and appropriately preserve and utilize it, basic investigation should be conducted to grasp the current situation of the burials. Additionally, excavation surveys and research are needed to understand the nature of the tombs. Based on this activity, local people should be informed about the importance of the tombs and participate in the preservation and utilization activities together. Preservation and utilization should be of the complex type. However, it should be improved systematically based on the fact that the tombs have not been properly investigated. In order to do this, the related organizations and budgets should be allocated at all times in Namwon City.

This paper considers a multistage experiment. Response scales can be same or different from stage to stage. When variables are of nested structure, the response variable at each stage can be defined conditionally. For analysing such data with compound scales, this paper suggests a sequnce of dependence models and shows how to set up a sequence of models for the driver's liscense test data.

This study was to investigate the relationship of BMI, sleep time and experience of oral diseases in adolescents. We want to help develop basic data for improving oral health of adolescents. According to the sample design of the Youth Health Behavior online survey, a total of 57,303 adolescents were analyzed for frequency of composite samples, x2-test of composite samples, and logistic regression of composite samples, and the IBM SPSS Statistics 20.0 program was used and the significance level was 0.05. Results, BMI was associated with bad breath, and sleep time was associated with tooth break, pain, bleeding, and bad breath. Therefore, BMI and sleep time should be considered for the management and prevention of oral diseases in adolescents.

Generally, a silicone rubber and a chloride polyethylene(CPE) have been used for the development of high-performance composite EM(ElectroMagnetic) wave absorber. In this study, the EM wave absorption abilities for natural lacquer which is newly suggested in this study as a binder for composite EM wave absorber were investigated to develop an improved EM wave absorber In addition, MnZn ferrite composite EM wave absorber mixed with the natural lacquer were prepared and their absorption ability was also investigated. MnZn ferrite composite EM wave absorber which employs the natural lacquer as a binder showed an improved EM wave absorption characteristics in comparison with the conventional binder such as a silicone rubber and a chloride polyethylene(CPE). The matching frequency and the absorption ability of EM wave absorber mixed with natural lacquer can be controled the change of the thickness of them.
