Mobile technology is accelerating innovative changes across all fields of our society as well as business environments. Especially, demands on mobile government (M-government) services have been increased gradually since e-government has improved national administration services dramatically. However, high-quality services which are acceptable to may users are not actually supplied because technical issues such as security on mobile e-government services have not solved and governance policy was not established yet. Previous studies show that most researches are devoted to technical ones or limited to theoretical exploratory study. As a result, developing useful guidelines which are practically and theoretically proved is one of the very important research issues. This study reviews the previous research works such as concept of mobile, e-government, M-government, technical trends of mobile, market situations, present status, and various case studies. And then we develop a research model with five factors, twenty four variables and seventy six measurement for measuring the influencing factors to adoption of M-government services. The model is composed of total 16 hypotheses, 22 variables, and 76 measurements. The model is analyzed by using statistical package SPSS (18.0) and AMOS (18.0) together with structural equation method based on 294 samples. The results show that the model is valid and there are statistically significant influence between ease of use and usefulness, ease of use and user's satisfactions, usefulness and intent of re-use, and user's satisfactions and intent of re-use, excepting usefulness and user's satisfaction, ease of use and intent of re-use did not affect significant influences. Especially, service quality, system quality, and relationship quality are identified as influencing factors to adaption of M-government service. The results are expected to provide a theoretical research framework which generate new research issues in M-government service area. It also can provide an useful guidelines to practical experts in successfully implementing M-government services. Further research directions are as follows. User's intents have to be studied in details by classifying users by individual, enterprise, and government as well as developing a new hypothetical model. Since M-government service is at the initial stage, longitudinal studies have to be conducted to trace the peoples' need in order to develop new high-quality mobile services.

The transformation of the processes of governance using the Information and Communication Technologies is aimed at bringing in faster and transparent service delivery, accountability, information sharing and people participation in the decision-making and government processes. The implementation of e-Government requires a comprehensive strategy that is not only sensitive to existing political and economic conditions and realities but is also benchmarked on global best practices. The article reviews the handbook E-Government and Governance Efficiency that provides an insight to research that is being undertaken in the e-Government area, gives an in-depth understanding of critical issues involved in e-Government, and provides expert opinion and recommendations for the Republic of Belarus to augment its potential. It studies the Korean experience on e-Government with special focus on such concepts as e-Government benchmarking, mGovernment, Smart Government and u-Government.

In this study, we compared nutrient content emphasized on labelling of processed milks with that of whole milks and evaluated how well they conform to labelling standard. A total of 98 samples (33 whole milks, 28 calcium fortified milks, 30 low-fat milks and 7 lactose hydrolyzed milks) were collected in hypermarkets in Seoul from August 28 to August 30 in 2012. Calcium, fat and lactose contents were tested in the samples. Calcium contents ranged 102.2~113.0 mg/100 mL in whole milks and 120.1~337.8 mg/100 mL in calcium fortified milks. The level of calcium contents in fortified milks ranged very broad. Accordingly, the standard of calcium contents on fortified milks will be required. Fat contents ranged 3.1~3.9 g/100 mL in whole milks and 0.1~1.9 g/100 mL in low-fat milks. The average of fats content in low-fat milks was nearly one third than whole milks. Lactose contents was ranged 4.6~5.1 g/100 mL in whole milks and not detected in lactose hydrolyzed milks. All of processed milks were suitable to processing standard and labelling standard. But nutrition claims often used on processed milk such as "High" or "Low" were not adequate to indicate the exact nutrient content, which is a cause of the confusion for milk product labelling to consumers. We need a lot of research about nutrient labelling that can deliver appropriate and understandable information to customers.

In this paper, we study a k-out-of-n system with single server who provides service to external customers also. The system consists of two parts:(i) a main queue consisting of customers (failed components of the k-out-of-n system) and (ii) a pool (of finite capacity M) of external customers together with an orbit for external customers who find the pool full. An external customer who finds the pool full on arrival, joins the orbit with probability ${\gamma}$ and with probability $1-{\gamma}$ leaves the system forever. An orbital customer, who finds the pool full, at an epoch of repeated attempt, returns to orbit with probability ${\delta}\;(<\;1)$ and with probability $1-{\delta}$ leaves the system forever. We compute the steady state system size probability. Several performance measures are computed, numerical illustrations are provided.

The purpose of this study were to collect the data for searching the better day care service programs among the employed mothers of the urban low income class. The Subject were 280 low income class employed mothers with the child under age of six, who lived at the Gwang-ju City. The frequency, percentage, and χ2test were calculated for the analysis of the collected data. The Results were as follows ; 1) Most of the urban low income class employed mothers needed day care facilities. 2) Urban low income class employed mothers preferred a center-based day care program to any other type of day care program. They also preferred the whole-day day care service 8 A.M. to 6 pp.M. rather than the half-day care service. Mothers with the child at the age of 3 to 6 years mostly wanted day care program service. 3) They expected the government or their companies to support considerable amount of day care service fee. Most of mothers emphasized the child's every day life's and love for the children was most preferred. Mothers also wanted 14-16 years for teacher's education career.
