Mobile web applications are different from desktop web applications because of their small screen size and small user input devices. Therefore user interface designers have spent their effort and time to re-design the user interface of mobile web applications to meet these differences. In this paper, we introduce five user interface patterns for mobile web applications to reduce their effort and time. Two of them are for utilizing small screen size efficiently, and they are space overloading pattern and data filtering pattern. These patterns enable designers to reduce screen usage. The other three patterns - data suggestion pattern, input reuse pattern, and incremental data input pattern - are for helping users' data input on mobile devices. These three patterns enable users to reduce direct data input. Our work will help user interface designers develop mobile web interface to utilize screen space efficiently and get data with less errors and less efforts from users.

In this study, we introduced the concept of ‘case-method’ which is the method to discuss about actual education with a concrete case. And we suggested that case-method need to be applied a program for mathematics teacher professional development. To assist this suggestion, we attempted to examine recent mathematics educational studies that is written by case-study and topics that is included in mathematics teacher educational program. After these examination, we pointed out that case-method with a educational case have not applied in teacher education program in korea. According to the suggestion in this study, we showed a concrete example of case-method. In this example, we set up three perspectives(on general theory of mathematics education, on contents of given case, on application given case to own class) to analysis given case and revealed several disscussion topics each perspective. Finally, we referred to the following research of this paper.

This research intends to check what value and convenience the on-line brand community members pursue and how such value and convenience affects brand affection. Researching on-line brand community members of ipod, it was found that their value and convenience is composed of 3 types, namely, functional value, emotional value and self-expression value and the concept of brand affection is composed of 3 subsidiary factors, namely, 'love', 'interest' and 'immersion.' Checking how the functional, emotional and self-expression convenience of on-line brand community members affected brand affection, the following result was found. First, functional value and convenience has significant influence on the love affection only at the level of brand affection and has no influence on the relational and immersion affection. Second, self-expression value and convenience has significant influence only on the love affection of brand like functional value and convenience. Third, it was found that emotional value has significant influence on the 3 dimensions of brand affection, namely, love affection, interest affection and immersion affection.

Dynamic compaction is the ground improvement method by applying the impact energy. This impact energy can damage to adjacent structure in urban area. Therefore, if dynamic compaction method is applied, careful attention should be payed to surrounded structures. In this study, the method was performed in waste landfill and the frequency of vibrations were measured according to each distances, drop-heights, and vibrating directions. The measured data show that particle velocity bas low frequency and it is greatest in longitudinal direction. There was little differences between Maynes suggestion and measured data. Therefore, Maynes suggestion can be adopted if the range of vibration can be predicted. Also, It was found that minimum 45m distance is needed in order to satisfy the administrative code if dynamic compaction method is applied.

The purpose of this study is to reveal the development process of modern repair systems in the Korean peninsula. Sasungjeon, one of the main buildings of Jangansa temple located in Geumgangsan, was repaired from 1941 to 1944. It was the very last restoration work of historic wooden architecture performed during the Japanese colonial era. This work was delayed multiple times because of insufficient materials and human resources. The Bureau of Education(學務局), which was in charge of repair work, understood that the problems of the repair system and suggested reorganizing the system as a solution. This study examined the repair work of Sasungjeon as a background of the bureau's suggestion and considered this suggestion as an attempt to transform the repair system.

Purpose The purpose of this study is to analyze the current state of grounded theory methodology in Korea information systems studies and to suggest its application strategies. Design/methodology/approach After reviewing previous studies, this study reviewed 16 papers which adopted grounded theory methodology and analyzed these papers by two ways, research contents and methods adopted from grounded theory methodology: Main characteristics in grounded theory methodology are selected as main criteria in analysis such as data collection method, constant comparison, software use, coding ways, suggested model, proposition suggestion etc., while subject, theory/practice orientation, and role of prior knowledge are included in research contents. Findings Based on the review and analysis, this paper suggested four guidelines for adopting grounded theory methodology to information systems research in Korea: First, division of research methodology into stages. Second, explicit documentation of research process. Third, pursuit of diversity in research topics. Fourth, strengthening scale up and theoretical integration.

Emerging digital economy, e-business, especially business to business(B2B) electronic commerce is understood one most single critical competitive weapon for organizations' global competitiveness. According to government white paper, Korea's electronic commerce records expansion stage in its volume and variety. Although Korea has remarkable EC records, still some differences are existed compare to the developed countries. IT in the developed countries, played an engine for the economic restructuring as well as for the economic growth. But in Korea, it's not fully utilized by the reasons of economic and noneconomic bottlenecks. Under the digital economic surroundings, EC or e-Business, is a business system to achieve the economic efficiency in the levels of an organization as well as a nation. So, we have to find the ways to utilize our EC infrastructure to contribute for the nation's global competitiveness. To find the way, this study recommends two types of policies, pull and push, beyond the OECD's suggestion, to government in order to expansion of EC, especially B2B EC.

The aim of this paper is to show how LCA(Life Cycle Assessment) is used as a tool to evaluate the environmental burdens associated with EMU(Electronic Motor Unit), especially one of main components, an interior panel. Thus, the LCA results are polished into the general environmental product declaration format to communicate with the industrial and institutional customers. The format includes the product information and environmental information. In the list of environmental information, profile is consisted of two major results from the LCA study. One is the inventory analysis and the other is the characterized impact results. The format shown in this paper can be the one of option to choose environmentally preferable product and suggestion aimed at the institutional consumer such as government procurement office and corporation's purchasing department.

BTL projects, which has been 3 years since it was carried out in 2008, trigged the controversy on the adequacy in the calculation of disbursement for Government due to such problems as low earning rate and the burden of service level compared with the project suggestion. Thus, the purpose of this study is to offer a suggestion on the calculation system for the purpose of the standardized - expense appropriation by item and database including the antecedent study on the finance model and the feasibility in BTL projects. The system is composed of 4 steps - project management, basic database, an analysis on expense by item and the result, and an analysis on sensitivity, and it is possible to carry out a comparative analysis on single and multi alternatives by variable change along with the ground on expense calculation.
