  • The IHO S-100 is a standard on the universal hydorgraphic data model for supporting information services that integrate various data in maritime and provide proper information for safety of vessels. The S-100 is used to develop S-10x product specifications which are standards on guideline for creation and delivery of specific data set in maritime. The product specification for feature-based data such as ENC(Electronic Navigational Chart) data includes a feature catalogue that describes characteristics of features in that feature-based data. The feature catalogue is developed by domain experts with knowledge on data of the target domain. However, it is not feasible to develop a feature catalogue according to the XML schema by manual. In the IHO TSMAD committee meeting, needs of developing technology on building feature catalogue has been discussed. Therefore, we present a feature catalogue builder that is a GUI(Graphic User Interface) system supporting domain experts to build feature catalogues in XML. The feature catalogue builder is developed to connect with the FCD(Feature Concept Dictionary) register in the IHO(International Hydrographic Organization) GI(Geographic Information) registry. Also, it supports domain experts to select proper feature items based on the relationships between register items.

  • With the development of the technology of underwater moving bodies, the need for developing the knowledge of surface effect interaction of free surface and underwater moving bodies is increased. Hence, the two-phase flow is a subject which is interesting for many researchers all around the world. In this paper, the non-linear free surface deformations which occur during the water-exit of a circular cylinder due to its buoyancy are solved using finite volume discretization based code, and using Volume of Fluid (VOF) scheme for solving two phase flow. Dynamic mesh model is used to simulate dynamic motion of the cylinder. In addition, the effect of cylinder mass in presence of an external force is studied. Moreover, the oblique exit and entry of a circular cylinder with two exit angles is simulated. At last, water-exit of a circular cylinder in six degrees of freedom is simulated in 3D using parallel processing. The simulation errors of present work (using VOF method) for maximum velocity and height of a circular cylinder are less than the corresponding errors of level set method reported by previous researchers. Oblique exit shows interesting results; formation of waves caused by exit of the cylinder, wave motion in horizontal direction and the air trapped between the waves are observable. In 3D simulation the visualization of water motion on the top surface of the cylinder and the free surface breaking on the front and back faces of the 3D cylinder at the exit phase are observed which cannot be seen in 2D simulation. Comparing the results, 3D simulation shows better agreement with experimental data, specially in the maximum height position of the cylinder.

  • Recent development of teachable agent provides learners with active roles as knowledge constructors and focuses on the individualization. The aim of this adaptive agent is not only to maximize the learner's cognitive functions but also to enhance the interests and motivation to learn. In order to establish the relationships among user characteristics and response patterns and to extract the algorithm among variables, we measured the individual characteristics and analyzed logs of the teachable agent named KORI (KORea university Intelligent agent) through the student modeling. A correlation analysis was conducted to identify the relationships among individual characteristics, user responses, and learning outcomes. Among hundreds of possible relationships between numerous variables in three dimensions, nine key user responses were extracted, which were highly correlated with either individual characteristics and learning outcomes. The results suggest that certain type of learner responses or the combination of the responses would be useful indices to predict the learners' individual characteristics and ongoing learning outcome. This study proposed a new type of dynamic assessment for individual differences and ongoing cognitive/motivational learning outcomes through the computation of responses without measuring them directly. The construction of individualized student model based on the ongoing response pattern of the user that are highly correlated with the individual differences and learning outcome may be the useful methodology to understand the learner's dynamic change during learning.

  • Purpose: The purpose of this study was to develop and apply a motivation-strengthening obesity management program for obese subjects with visual impairment and evaluate its effects. Methods: The program development and evaluation periods were from March to August 2018. The study design was an experimental study of non-equality, control repeat design. 25 subjects in the experimental group participated in the 12-week obesity management program and the 26 people in the control group did not. Results: The motivation-strengthening obesity management program included stretching exercises for 30 minutes in the morning five times a week. In addition, counseling, education, and group discussions were continued once a week for motivational strengthening. Special custom exercises for blind patients were also completed once a week simultaneously. Both of these activities were continued for 50 minutes a week for a total of 12 weeks. Measurements were recorded periodically to identify the sustained effects of the program. The obese subjects with visual impairment improved their knowledge of obesity, perceived disability, self-efficacy of exercise, and quality of life related to obesity through the motivational obesity management program. Waist circumference, systolic blood pressure, diastolic blood pressure, and fasting blood sugar were also improved in obese subjects. Conclusion: The study findings indicate that this program could be an active intervention for the control of weight gain in participants with visual impairment. Therefore, the motivation-strengthening program based on the ADDIE (Analysis, Design, Development, Implementation& Evaluation) model could be an effective strategy for better health outcomes of obese subjects with visual impairment.

  • Background: Cervical cancer is a common, preventable and manageable disease in women worldwide. Objectives: This study was conducted to determine the cost of follow-up for suspicious precancerous cervical lesions within a screening program using Pap smear or HPV DNA test through the decision tree. Materials and Methods: Patient follow-up processes were determined using standard guidelines and consultation with specialists to design a decision tree model. Costs of treatment in both public and private sectors were identified according to the national tariffs in 2010 and determined based on decision tree and provided services (visits to specialists, colposcopy, and conization) with two modalities: Pap smear and HPV DNA test. The number of patients and the mean cost of treatment in each sector were calculated. The prevalence of lesions and HPV were obtained from literature to estimate the cost of treatment for each woman in the population. Results: Follow-up costs were determined using seven processes for Pap smear and 11 processes for HPV DNA test. The total cost of using Pap smear and HPV DNA process for each woman in the population was 36.1$ and 174$ respectively. Conclusions: The follow-up process for patients with suspicious cervical lesions needs to be included in the existing screening program. HPV DNA test is currently more expensive than Pap smear, it is suggested that we manage precancerous cervical lesions with this latter test.

  • Purpose - The ICT(information and communications technologies) development is affecting consumer behaviors on selecting channel or distribution system. This study aims to advance our knowledge about the factors influencing omni-channel behaviors. This study considers the positive brand experience as the moderating variable into the relationship between omini-channel use intention and consumer brand relation. Also, the effect of positive brand experience on consumer-brand relation is researched. Research design, data, and methodology - This study conducted an empirical test with the subject as customers who purchase goods or service through on-off cross channel simultaneously. The research model is developed from prior literatures about influencing variables on channel selection. The structure of this study is designed to identify causal relationships between the variables. 268 survey data from the questionnaire survey which is conducted to target customers who use online and offline channels, is used for empirical analysis. This study validates generality with descriptive statistics and data reliability with Cronbach's alpha value. The exploratory factor analysis is used for value purification. Then, the confirmatory factor analysis is conducted for structural equation modeling. Finally, the execute structural equation modeling is analyzed to confirm the hypotheses Results - First, the two causal influences between perceived performance risk and the propensity of omni-channel and between price consciousness and the propensity of omni-channel are verified through the empirical test. Second, the result identifies that the propensity of omni-channel is influenced on consumer-brand relationship. Third, the AMOS analysis proves that the moderating variable, positive brand experience, has significant positive impact on consumer-brand relationship. This significant relationship is highly supported by the regression analysis between brand experience and propensity of omni-channel because it results that positive brand experience has positive impact on the propensity of omni-channel. All hypotheses are verified to be true. Conclusions - Based on the empirical result, this study confirms that perceived performance risk and price consciousness are the important factors influencing propensity of omni-channel. According to the additional analysis, the moderating variable and positive brand experience plays important role between the propensity of omni-channel and consumer-brand relationship. Furthermore, positive brand experience influences more on consumer-brand relationship than non-positive brand experience.
