The objective of this research is to evaluate the web standard as well as web compatibility of English homepage of tourist information manage local government. Thru this research, effective information and service can be provided to increasing foreign visitors and compatibility of English homepage can be strengthened. SortSite, a web compatibility measurement tool and UNICORN, a web standard measurement tool were utilized for this research. Chrome, Internet Explorer, Firefox, Safari and Opera were targeted for evaluating web compatibility and observance rate of Markup grammar and CSS grammar was checked for evaluating web standard. Research result showed that 46.7% of Chrome version ${\leq}34$ and 35 didn't observe the web compatibility while 95.6%, 53.3%, 53.3%, 53.3% and 55.6% of Internet Explorer version in order of 7.0, 8.0, 9.0, 10.0 and 11.0 didn't observe the web compatibility. Concerning Firefox, 75.6% and 48.9% of version in order of ${\leq}6.0$ and 7.0 didn't observe the web compatibility and 37.8% of Opera version ${\leq}12.17$ and ${\leq}21$ didn't observe the web compatibility. Regarding the web standard, 80% of English homepage didn't observe Markup grammar and 60% of them didn't observe CSS grammar. Therefore, urgent improvement of web compatibility and web standard is required.

The propagation of smart devices and the rapid expansion of wireless mobile networks have increased the need for ubiquitous device connectivity and contents access. DLNA is currently being used as the de facto standard for connectivity of consumer devices in the digital home. The guidelines provided by DLNA are intended to facilitate device and contents discovery, management, sharing and distribution. However, consumer experience with DLNA has been rather poor and usability not up to speed. Different problems and issues in limited compatibility have been reported due to manufacturer customizations. Such compatibility issues are often difficult to identify by average consumers who are not savvy in information communications and multimedia technology. In this paper, the design and implementation of a DLNA protocol inspection tool is presented for compatibility analysis among DLNA certified devices. The tool monitors the home network and performs analysis of the underlying protocols used by DLNA. The tool can be used for diagnostics and troubleshooting, enabling the user to identify compatibility issues between devices or problems in the network.

This article develops the perceived attributes of fashion goods and hierarchical structure among these attributes. In-depth interviews of 12 adult women in the exploratory research and a questionnaire survey of 472 adult women in the empirical research were conducted. The results of the research are as follows: First, a total of 5 perceived subjective attributes of fashion goods are composed of newness, mass fashionability, social compatibility, personal compatibility and self-expressiveness, and the dimensions of the five drawn attributes show a hierarchical causality rather than an equal level. Newness and mass fashionability, perception attributes effect social compatibility and personal compatibility as consequence attributes exert a direct influence on the self-expressiveness represented by value attributes. Personal compatibility and social compatibility as consequence attributes also directly effects self-expressiveness while mediating newness and mass fashionability.

The COMS(Communication, Ocean & Meteorological Satellite)is the geostationary satellite which will be performing three main objectives such as meteorological service, ocean monitoring and Ka-band satellite communications. This paper presents the analysis of the electromagnetic radiated compatibility between COMS satellite and the ARIANE 5 launch vehicle. As a conclusion, a good level of confidence can be given at present time to demonstrate the compatibility between the spacecraft and the launcher, and vice versa. No threat has been identified regarding the other units powered during launch mode.

The dimensional measurement equipment, such as Coordinate Measurement Machine (CMM), Optical Coordinate Measurement Machine (OCMM), and Checking Fixture (CF), take multiple dimensional measurements for each part in an automobile industry. Measurements are also recorded under different measurement systems to see if the responses differ significantly over these systems. Each measurement system (CMM, OCMM, and CF) will be considered as different treatments. This set-up provides massive amounts of process data which are multivariate in nature. Therefore, the multivariate statistical analysis is required to analyze data that are dependent on each other. This research provides step by step methodology for the evaluation procedure of the compatibility of measurement systems and clarify a systematic analyzation among the different measurement system's compatibility followed by number of case studies for each methodologies provided.

Purpose: The purpose of this study was to identify the effects of husband and wife compatibility and self efficacy on health promotion behavior and define the main factors influencing health promotion behavior in middle aged women. Method: Using a structured questionnaire, data were collected from 311 middle aged women. Descriptive statistics, Pearson correlation coefficient, Stepwise multiple regression with SAS package were used for data analysis. Results: The mean score of husband and wife compatibility was 3.55(${\pm}.56$), self efficacy was 3.51(${\pm}.54$), and total health promotion behavior was 2.91(${\pm}.37$), with scores for subcategories as follows: interpersonal support 2.86(${\pm}.59$), self-actualization 2.74(${\pm}.56$), nutrition 2.56(${\pm}.63$), health responsibility 2.32(${\pm}.60$), stress management 2.28(${\pm}.51$), and exercise 1.87(${\pm}.74$). Husband and wife compatibility, and self efficacy were positively related to health promotion behavior and all subcategories of health promotion behavior. Also husband and wife compatibility were positively related to self efficacy. The major factors that affect health. promotion behavior in middle aged women were husband and wife compatibility, self efficacy, economic level, and religion, which explained 32.6% of health promotion behavior. Conclusion: The results indicate that health promotion behavior may be increased through interventions directed at improving the husband and wife compatibility.

It is a general phenomenon for manufacturers to provide vertically differentiated product line for more profit through improved market coverage. For such manufacturers, the compatibility between vertically differentiated products is an important decision issue. Some manufacturers provide full compatibility between high and low version products, whereas some provide only downward compatibility for the purpose of recommending high version product. In this study, the two representative compatibility strategies, full or downward, between vertically differentiated products produced by a single manufacturer are analyzed, especially under network externality and in the viewpoint of profit maximization. To do this we used a market model which captures the basic essence of vertical differentiation and network externality. Based on the proposed market model, the profit maximizing solutions are derived and numerically analyzed. The results can be summarized as follows : (1) Regardless of compatibility strategy, under network externality, vertical differentiation is always advantageous in terms of profit. (2) The full compatibility strategy is shown to be the most advantageous in terms of profit. In addition, it is necessary to make quality difference between differentiated products as wide as possible to maximize profit. (3) To gradually drive low version product out of the market and shift the weight pendulum of market to high version product, it is shown that the downward compatibility strategy is essential. Unlike intuition, however, it is also shown that in order to drive low version product out of market, it is necessary to raise the quality of the low version product rather than to lower it.

Eurostar 3000 AOCS is optimized for telecommunication mission with no strong requirement on attitude stability and has therefore to be upgraded to comply with COMS high stability requirements for the optical observations. This COMS configuration constraint induces specificities for the wheel. The aim of this analysis is to verify the electrical compatibility of the interfaces which exist between COMS wheels and external equipments. For each interface, this study checked the compatibility between equipments for the power links, commands, digital telemetry, analog telemetry, and failure condition or AIT errors. In addition with this interface compatibility verification, this study outputs electrical and manufacturing recommendations to be applied at harness level.
