This research developed a strategy for mobile banking services based on the important factors deduced from quality assessment of mobile banking service that is experiencing rapid growth of user. SERVQUAL model and importance-performance tool were used. First, SERVQUAL model uses the important factors of mobile banking service selected from literature reviews. As a result, four dimensions that affect user satisfaction are found; assurance, customer orientation, tangibility, and reliability. Second, importance-performance analysis is to develop the strategy using the four factors. The final results revealed that assurance dimension had the strongest influence on user satisfaction. Assurance dimension of high expectation and yet low real performance needs immediate improvement. Customer orientation dimension of low expectation and performance should be reconsidered definition of satisfaction. On the other hand, tangibility dimension of higher performance than expectation is simply to maintain current level. Reliability dimension of high expectation and performance is recommended consistent management.

One of the main issues related to the precipitation amounts measured by the Korean raingage, Chukwookee, invented by King Sejong is the discontinuity in the time series around 1907 when the modern raingage was first used in Korea. To solve this discontinuity problem Wada(1971) reproduced the Chukwookee data but many authors questioned the validity of Wada's method. In this paper we analyze the precipitation amounts in Seoul from 1771 to 1994 using the intervention model and show that Wada's method results in the overestimation of the precipitation amounts. We also propose a reproduction method by considering monthly constant and including the rainfall of less then 2 mm and the snowfall which were ignored previously.

The purpose of this study was to verify the validity of Ohio State Teacher Efficacy Scale(OSTES: Tschannen-Moran, 2000) when used with Korean home economics teachers. To achieve this purposes, the surveys with 263 secondary school home economics teachers was conducted by the prime investigator. Statistical procedures included descriptive statistics, factor analysis, internal consistency. Cronbach's a was calculated to test the reliability of items and their internal consistency and Exploratory Factor Analysis(EFA) was conducted to test the structure of each factors with principal analysis and varimax rotation. Confirmatory Factor Analysis(CFA) was conducted to test the factor validity of this scale with AMOS program. The reliability test result of 20 items appeared Cronbach's a=.86. The factor analysis on teacher efficacy with 263 survey of secondary school home economics teachers produced 5 factors including efficacy in classroom management. efficacy in needs assistance, efficacy in instructional strategies, efficacy in environmental assistance and efficacy in teaming assistance. The validity of teacher efficacy scale was moderately verified by the confirmatory factor analyses(GFI=.87, AGFI=.84. CFI=.86. PNFI=.72, RMR=.05. RMSEA=.07). The results lend a support to the teacher efficacy scale as a valid instrument.

The purpose of this study is to construct the evaluation model for the major science research facilities and equipments to enhance the competitiveness of the science and technology and also to test the reliability and validity of the model. To achieve the purposes, this study theoretically reviews the concept of the major science research facilities and equipments and their characteristics. Through a review of literature, this study draws 11 criteria for evaluating the priorities of the major science research facilities and equipments. These criteria are categorized as two dimensions - 'science & technology' and 'national policy'. The dimension of science & technology includes scientific importance, technological readiness, utilization rate, common utilization rate, and ability of management and operation. The national policy dimension contains degree of correspondence with national science development, imperativeness of national policy, science and technical effectiveness, economic and industrial effectiveness, responsiveness of research demand, and equity among the related institutions. The competitiveness of the science and technology consists of these two dimensions. The evaluation model is established on the framework of criteria. The 18 major science research facilities and equipments are selected through a series of Delphi. The survey of experts (BT, ET, IT, NT and ST) is also implemented to evaluate the 18 major science research facilities and equipments by 11 criteria. The overall results indicate that the reliability and validity of the model are good. The reliability tests show that the five indicators of science & technology and the six indicators of national policy have high internal consistencies. The confirmatory factor analyses reveal that the two constructs - 'science & technology' and 'national policy' - have high convergent and discriminant validity. The correlational analyses also show that the criteria-related validity between them is high. Furthermore, the results of higher order factor analysis indicate that the fit indices of the model are high and suggest a good fit to the data. Based on these findings, the policy implications of the model are discussed.

For a more convenient deduction of the weighted values in AHP of BSC using a spread sheet program, this study derived each weighted values through single and group calculations and it also compared the two calculations to verify mutual identities. Pairwise comparison is generally used in measuring performance of corporations or government organizations, but, many researches have been done without reliability verification due to difficulty in the deduction of weighted value. This trend, like using a wrong measurement, result in defective result of BSC. Therefore, this study presents various methods of single and group case measurement using spread sheet so that it can be utilized in practice. Thus, I expect this study's result be availed in BSC consulting or research of public organizations that have difficulty in measuring qualitative factors.
