People with obesity or over-weight need nutritional intervention to reduce their weight, because weight loss reduces the incidence rate of chronic diseases such as hypertension, type II diabetes, cardiovascular diseases and cancer in obese people. This study was to develop a system for individualized weight control program available both for wired and wireless internet users. This system is especially useful to users carrying wireless internet mobile device. If they input their physical information (height, weight and waist circumference) and mineral levels measured by hair tissue mineral analysis, the system provides evaluation of their health status and metabolic related functions such as endocrine and carbohydrate tolerance. Based on these evaluations, food menus are then offered to them to manage their health status and to improve their metabolic related physiological functions in a personalized way. The system also provides more information for recommended foods, such as nutritional information, food ingredients, recipes, and videos related to cooking. Bibimbap was selected as an example dish for customized contents for mobile web. Bibimbap is one of the most well-known Korean traditional dishes prepared with various kinds of ingredients including several different kinds of vegetables, meat, and egg so that it is a low calorie dish as well as a well-balanced diet. Therefore, this system developed in this study allows the mobile users to access web site through wired wireless internet everywhere and provides a customized content to the users to manage their weight and finally to achieve a desirable weight.

Recently, mobile internet technologies are enabling the possibility of radically new computing services which can share information and communicate with others on the move. In this situation, prior studies have attempted to identify of what factors make people use mobile internet. However, prior researches focused on investigating the factors affecting users' adoption to Mobile Internet. In order to offer beneficial materials to mobile internet companies, we investigated important factors to increase mobile users' value from the viewpoints of customer. In particular, this study was progressed how characteristics of mobile contents affect users' intrinsic attributes and how perceived users' network effects affect users' value in the mobile computing environments. To empirically test proposed hypotheses, we have analyzed 285 survey data gathering from mobile internet users and verified hypotheses by using SEM (structural equation modeling). Based on the results of this study, we found that content accessibility and content quality have significant impacts on users' intrinsic attributes such as perceived usefulness and perceived enjoyment. In addition, this study also revealed that perceived usefulness and perceived enjoyment were positively related to users' emotional value. Moreover, this study found that perceived users' network effects could affect users' monetary value by mediating expected benefits. Based on our findings, we can understand that this perspective can provide a deeper understanding of the mobile users' value adoption by bridging the gap between mobile internet studies and actual practice.

This paper proposes a control method of ASMR(autonomous sensory meridian response) contents to relieve user's stress and improve his attention. The proposed method measures EEG(electroencephalography), attention, meditation, and eyeblink data from an EEG device and sends them to an oneM2M-compliant IoT(internet of things) server platform through an Android IoT Application. Then a SVM(support vector machine) model is built to classify user's mental health status by using EEG, attention and meditation data collected in the server platform. The ASMR contents are controlled by the mental health status classified by a SVM model and the eyeblink data. When comparing the SVM models according to types of data used, the SVM model with attention and meditation data showed accuracy of 85.7%. It was verified that the proposed control algorithm of ASMR contents properly worked as the mental health status from the SVM model and the eyeblink data changed.
