본 논문은 모바일 환경의 특성을 고려한 사용자 맞춤형 원스탑 정보 서비스 시스템에 대하여 기술한다. 모바일 환경은 그 이름대로 휴대성을 가장 큰 장점으로 한다. 그러나 아직까지 정보 입력 및 표현의 한계성은 극복되지 못하고 있다. 따라서 복잡하고 방대한 인터넷 서비스를 모바일 환경상에 구현하기 위하여는 사용자에 최적화된 서비스만이 구성되어 제공되어야 한다. 본 논문은 이러한 문제점들을 극복하기 위해 "사용자 맞춤형 원스탑 정보 서비스(One-Stop Service: OSS) 시스템" 을 제시한다. OSS 시스템은 사용자 맞춤형 정보 제공을 위해 개인화 기술을 이용한다. 여기서 OSS 란 다양한 서비스들의 집합으로 사용자 취향에 적합하게 동적으로 생성된 서비스의 묶음을 말하는 것이다. 본 논문에서 제안하는 시스템은 향후 모바일 환경 어플리케이션이 나아가야 할 방향을 제시하고 있다는데 그 의미가 있다.

The aim of this study was to analyze a group of pre-service elementary teachers experience on the cognitive terms of biology inquiry subjects, and experience on living materials related with the domain of life in the Korea elementary school science textbook. Firstly, elementary school pre-service teachers had the confidence of inquiry subjects related with the domain of life such as 'when we take breath what will happen in human body?' and 'Can we make the model of human body?' But they did have the most diffidence of 'The search for pieris rapae, a cabbage butterfly's life', 'Can we grow the little creature?' The reason why pre-service elementary teachers had diffidence of comprehending experiment procedure and planning ability was that 'they focused on understanding the scientific concepts instead of planning experiments by themselves', and 'they carried out the least amount of experiments' Secondly, elementary school pre-service teachers had never experienced biology materials related with the domain of life in the Korea elementary school biology science textbook such as 'tradescantia reflexa', 'Caddis larva', 'hydrilla verticillata', and 'Plantain lily.' According to the findings obtained from the study, the reason why they had never seen the biology materials was that they had the least opportunity of immediately observing life creatures due to memorization-intensive classes.

This study was performed to suggest a new efficiency measurement indicator is necessary for evaluating management efficiency of food service operations in contract-managed foodservice companies, to distinguish efficient food service providers and inefficient ones by measuring comparative efficiency among food service operations, and to provide guidance for effective management through showing benchmarking targets for improving inefficient food service providers. The subjects of this study were the 93 B&I foodservice Operations of a domestic contract food service company. The analysis was conducted using CCR model in DEA model. A software, 'Frontier analyst', was used for the analysis. Based on the results derived from comparison of efficiency evaluation classified by providers with use of DEA, it was possible to identify efficient food providers and inefficient providers, and subsequently provide benchmarking guidelines for improvement of the inefficient groups. In analyzing the differences between the results of DEA efficiency evaluation by detailed operation status of food service providers, there was significant difference of efficiency outcomes in terms of contract types, while there was no significant difference in terms of business condition.

The purpose of this study was to assess the effects of perceived value and satisfaction with employees' foodservice on loyalty intention. A total of 273 questionnaires were completed. Structural equation model was used to measure the mediating role of satisfaction in the causal relationships among perceived sacrifice, service quality, value, satisfaction, and loyalty intention. Results of the study demonstrated that the structural analysis result for the data also indicated excellent model fit. The direct effects of perceived sacrifice and service quality on value were statistically significant. The direct effects of service quality and value on satisfaction were statistically significant. The direct effects of value and satisfaction on loyalty intention were statistically significant. The service quality had a significant indirect influence on loyalty intention through value and satisfaction. In addition, the value played a mediating role in the relationship between service quality and satisfaction. The satisfaction played a mediating role in the relationship between value and loyalty intention.

The purpose of this study was to investigate the current status of pre-service curriculums for child care teachers at universities and colleges in Korea. To accomplish this, a survey was implemented to gather the lists of courses from each department training pre-service child care teachers. A total of 225 departments at universities and colleges across Korea participated in the survey. The results showed that the 37 different courses offered for child-care teacher licensure were different by school type (university or college) and major. Departments in colleges with specific majors such as early childhood education and social welfare offer courses that are also required for other certificates, including kindergarten teachers or social workers, so pre-service child care teachers may not have the opportunity to take courses specifically designed for their specific teaching needs or interests. Accordingly, there may be a restricted number of courses from which to choose during pre-service training periods. Based on the findings from this study, several political implications for improving child-care teacher professionalism were suggested.

Purpose: We sought to investigate the operation status of internal accounting control systems in the distribution and service industries and verify whether investing in internal accounting personnel significantly influences the quality of the companies' financial reporting. Research design, data and methodology: We identified descriptive statistics and performed a univariate analysis. Furthermore, a regression analysis verified the impact of investing in internal accounting personnel on the absolute value of discretionary accruals, a proxy for financial reporting quality. Results: Distribution and service companies allocated a significantly higher number of accountants to their internal accounting control systems than companies in other industries. We also confirmed that the absolute value of discretionary accruals significantly decreased as the average working experience of internal accounting personnel in distribution and service companies, in months, increased. Conclusions: In this study, we confirmed that distribution and service companies are devoting efforts to establishing internal accounting control systems and found that financial reporting quality is more effectively controlled as companies allocate more experienced personnel in their internal accounting control system.
