Purpose: In this paper, we provide an illustration of Indonesian youth Social Networking Service (SNS) behavior and its relation to their culinary activity. Specifically, their behavior of culinary activity preferences and also the factors affecting their action of spending their money. Data and methodology: We gathered primary data from stratified random questionnaire survey (406 youth). The gathered data was analyzed using text data mining and statistics using R statistical computing language. Results: 1) We found out why our respondents are interested in following the accounts of SNS food influencers: i.e. visually attracted to the posts, as their reference to find places to dine out, as their reference to try new food menu and to get nostalgic feeling about the food. 2) The respondents decide to actually go to the recommended culinary places because of several factors, specifically, its description (visual and text), location, word of mouth (WoM), the experience of being to that place and price. 3) Important factors affecting culinary spent are income, number of following food influencer account, SNS usage time and their interest when looking at WoM. Conclusions: SNS behavior influences Indonesian youth culinary activity preferences and spent.

Today, apartment is the most common residence type and various behavior occurs in living room space of apartments. Active usage of living room in modem life increases user's desire of wanting a better environment and leads to find various methods such as remodeling. At the point when considering moving or remodeling, this study focuses on the change of lighting color as it is one of the methods for initial stage with moderate price. As living room is easily influenced by lighting, providing active environment to support inhabitant's behavior through the use of various lighting sources will cut down unnecessary remodeling costs and may be the most simple method to actualize lighting environment for inhabitant's behavior. To give change with the least effort, change in artificial lighting environment was attempted with combinations of lighting color and switching on lights according to illuminating location. This study suggested the capability of changing lighting environment of previous living room area by exchanging lighting sources in lighting equipment in order to satisfy the required behaviors of inhabitant.

This study investigated the knowledge, attitude, and behavior of 280 University students towards nutrition labels. The purpose of the study was to examine knowledge, attitudes, and behaviors of university students regarding nutrition labeling, and whether body mass index (BMI) with nutrition labeling was associated with knowledge, attitudes, and behaviors. Descriptive statistics analyzed knowledge, attitudes, and behaviors of university students regarding food labeling. The ANOVA and ${\chi}^2$ analysis was evaluated and assessed for its relationship with BMI. Pearson's correlation coefficient analysis examined relationships between knowledge, attitudes, and behaviors. More than 90 percent of answers relating to 11 nutritional knowledge questions were correct. Only 30% of participants answered correctly regarding questions about plan source oil and cholesterol content. Attitudes and behaviors of nutrition labels were significantly higher among participants who were obese (p<0.001). Knowledge score was positively correlated with general label usage behavior (r=.169, p<0.01), and item buying behavior (r=0.142, p<0.05). Attitude also was positively correlated with behavior (p<0.01). Nutrition labeling education efforts are needed to provide university students with a nutritional education program and information on how to read nutritional labels and apply this information to their lives. University students need to understand their need for numerous nutrients instead of merely focusing on the fat and calories of foods.

The data were analyzed using frequency, percentage, factor analysis, chi-square test, ANOVA, duncan test. The results of our study indicate that it is possible to meaningfully describe and contrast four brand types based on consumer's characteristics and purchase behavior. 1. The clothing brand is classified into four types : Designer brand 10.9%, National brand 27.2%, Middle-price brand 36.2%, Low-price brand 25.7%. 2. There are significant diferences according to four brand types in the demographic traits such as age education and income the average monthly spending on clothing. 3. There are an important discrimination according to tow brand types in their clothing purchase behavior such as information usage, clothing choice criterion and brand choice motivation. 4. Based on the result of this analysis and the review of literature, the brand strategy is suggested that characteristic and products development is efficient way to each brand consumers' purchase need. Therefore each brand which pursue an added value must frame marketing strategy on the basis of the target consumers' sensitivity characteristic according to the fashion consciousness.

The purpose of this study is to suggest methods for the community design through users' behavior study in apartment housing. This study was approached by using both theoretical investigation and empirical research. The theoretical investigation actualized the concept of community design in apartment housing through a literature survey. The empirical survey focused on seeking out a user-oriented design criteria based on the analysis of residents' usage behavior and mental map. The results of this study are as follow: First. regarding the analysis of the residents' attitude toward the share community space(SCS), it was found that the SCS made a sense as community facilities in apartment housing. Second, regarding the SCS through the metal map, it was shown that the sketch map analysis was a useful research method for the community design by actualizing the residents' behavior characteristics. Third. as to the results of analyzing the metal map, it was found that the considered characteristics in recognition of the SCS were related to the liking with the main paths, cross nodes of the moving line, the location of center. and the complexity. In conclusion, the SCS is the main of community design in apartment housing and the above characteristics in recognition are useful as the guidelines in the SCS planning.

Component based development has increasingly become important in the software industry. However, in the current component based development approach with UML, the absence of behavioral description of components brings about a cost problem which causes semantic errors on the testing phase. Accordingly we cannot grasp the usage pattern of component by its provided interfaces which refer to an abstraction of software component. And we cannot guarantee the behavioral conformance of the provided and required interfaces of components. In order to solve these problems, we describe the behaviors of component interfaces by state machine diagram and guarantee their behavior conformance at the modeling phase. We also propose a method to guarantee the behavior conformance of component interfaces with concept of observation equivalence and invocation consistency. And we provide an analyzing tool which checks interface behavior conformance.

This exploratory study aims to understand the potential of log data analysis and expand its utilization in user research methods. Transaction log data are records of electronic interactions that have occurred between users and web services, reflecting information-seeking behavior in the context of digital libraries where users interact with the service system during the search for information. Two ways were used to analyze South Korea's National Digital Science Library (NDSL) log data for three days, including 150,000 data: a log pattern analysis, and log context analysis using statistics. First, a pattern-based analysis examined the general paths of usage by logged and unlogged users. The correlation between paths was analyzed through a χ² analysis. The subsequent log context analysis assessed 30 identified users' data using basic statistics and visualized the individual user information-seeking behavior while accessing NDSL. The visualization shows included 30 diverse paths for 30 cases. Log analysis provided insight into general and individual user information-seeking behavior. The results of log analysis can enhance the understanding of user actions. Therefore, it can be utilized as the basic data to improve the design of services and systems in the digital library to meet users' needs.

The purpose of this study was to find out the current status of smart phone usage, differences of developmental characteristics and time diaries between high- and low- usage groups. The study also tried predicting variables among children's personal and family environment factors in order to classify four year old children in the fifth year Panel Study on Korean Children into the two groups. Data was collected from 435 smart phone users and 157 of them who had started to use a phone before age 3.Frequency analysis, t-test and logistic regression were performed. The results showed that most 4 year old children started to use a phone in their fourth year and used it frequently. The low level groups of girls and all participants showed lower levels of behavior problems, and the low level group of all participants had a longer sleep times than the high level group had. Children's activity and social temperament were identified as predicting variables for classifying children into the two groups. The results suggested the necessity of measures preventing children from excessive smart phone usage in their early years and to consider children's temperament first.

System response times(SRTs) are getting important while increasing the function of system. In the past, most research studied SRTs on situation of computer usage. There are lacking the research on simple domain. This study focuses on behavioral and emotional effect on situation of cell phone usage(experience 1; independent variables: degree of SRTs, dependent variables: behavioral and emotional evaluation). And this study investigates the behavioral and emotional effect in same SRTs on different situation(experience 2; independent variables: degree of SRTs, usage mode, dependent variables: behavioral and emotional evaluation, stress, mental strain). The result indicated that long SRTs increased problem solving time and negative emotion. User evaluated the system differently according to usage mode after they performed the same task. In other word, if user had a strong goal, then they felt more negative emotion and mental effort than the user don't have a strong goal. In the goal mode group, it was important there are being of delay or not. This study demonstrated that SRTs and usage mode influence user's emotion and behavior performance in same task.

With the development of information technology, users are provided with information they want through mobile device in various situations. When users communicate with information, there is interaction through gesture activities such as tapping and experience in the process. Experience through interaction in mobile affect the user's psychology. This is important because it is related to the behavior of the user in the future. Various types of information presentation methods have been researched in mobile environment. However, there are more research focusing on functional interactivity. The purpose of this study is to investigate the effect of interaction and usage mode on satisfaction, usefulness, and intention to use for sound text presentation that is user-centered. As variables for my study, there are two factors which are interactivity and usage mode. The interactivity type is composed of two ways that are: High and Low depending on modality and message interactivity; and the usage mode is composed of Action mode and Goal mode depending on whether user has a task or not. The experimental design is $2{\times}2$. The same content is provided in (a) only Modality interactivity, and (b) Modality and Message interactivity are provided. Depending on usage mode, (a) Action mode is processed without a specific task, and (b) Goal mode is performed with a specific task to participants. The experimental study demonstrated that there is a difference in satisfaction, usefulness, and intention to use depending on the difference of interaction and usage mode when providing information in mobile environment. The results of this study are summarized as follows: interaction and usage mode have significant influence on mobile user's satisfaction, usefulness, intention to use.
