The economic effects of informatization are differently occurred according to industry types. Thus an evaluation methodology which reflects the industry type characteristics of informatization is needed. In this paper, we develop and analyze the indices for evaluating economic effects through informatization according to industry types, such as manufacturing, construction, financial services and marketing services. The factors related to performance of enterprise informatization can be defined as cost factors, effect factors, risk factors and influence factors. Effect factors are defined as quantitative or qualitative performance of informatization and classified into operational effect factors and strategic effect factors. The influence factor is defined as characteristics of informatization for industry types, that is, value chain of business and business products or services. Economic effect indices are classified according to the activity of business value chain. Economic effects indices of this research can be expected to play a role of general and standardized factors for economic evaluation of industry informatization.

The introduction and application of IT(Information Technology) to a company has become to be viewed as a key factor for the business competitiveness and improved productivity. This study presents an approach to evaluation of a company's informatization level, which is especially appropriate for small and medium enterprises. The proposed evaluation method, based on the traditional questionnaire approaches, considers the various characteristics of the company, e.g., types of business, characteristics of customers, and locations of supply chains etc. A web-based system was developed to enable users to obtain the evaluation results from the evaluation method. The system also provides a function to produce valuable strategies for informatization by utilizing the case base which will be cumulated by repetitive evaluation requests. Finally, a real case was analyzed in order to verify the practicality of the evaluation system.

This study examines the influence of smartphone use in old age on satisfaction with relationships with spouse, children and social acquaintances among Korean older adults. Data on older adults aged 60 and over, who live in Seoul, was collected through a questionnaire survey and 674 cases were analyzed. The effects of smartphone use on satisfaction with these three types of inter-personal relationships was tested using a multiple regression analysis, controlling for sex, age, marital status, education, employment status, income and health. The results showed that the smartphone use of older adults did not affect spouse relationship satisfaction, but positively affected both children relationship satisfaction and satisfaction with social acquaintance relationship in old age. This suggests that the positive effects of smartphone use on inter-personal relationships in old age work only to improve relationships with children and social acquaintances, but not to enhance the relationship with one's spouse. This study implies that practical efforts to enhance the smartphone use and the level of informatization among older adults are needed to improve the inter-personal relationships and quality of life in old age.
