The quality of navigation service is determined by the accuracy of the available data. For existing navigation services, a full map update is provided in order to keep the map data of mobile devices current. As content and services of mobile devices have recently been diversifying, the size of map data managed in mobile devices has increased, reaching several gigabytes in size. It generally takes tens of minutes to write several gigabytes of data into mobile device storage. For traditional navigation systems, a complicated storage structure called a physical storage format (PSF) is used to assure maximum processing performance of map data in mobile devices within limited resources. Consequently, even though modified navigation map data actually affects only a portion of a map, the full map data is updated because partial updates are not possible. In this paper, a navigation system is studied to solve this difficult partial map update problem. The map air update navigation system, which is the result of this study, provides real-time partial map updating using wireless communications.

The Public Data Act mandates that every public institution must make efforts to facilitate convenient access to public data for all and take necessary measures to universally expand the right to use such data. Furthermore, it specifies that the head of a public institution must provide the data held and managed by that institution to the citizens. The Construction Project Information Disclosure Service aims to increase the utilization of data within the Construction CALS System, creating new added value by disclosing information and fostering communication. This service seeks to enhance public interest and transparency, support the creation of new businesses based on construction project data, and stimulate related industries. Since 2019, a total of 26 types of information have been disclosed through this service. As the volume of disclosed information continues to increase, there has been a consistent demand for reducing burden on data providers and enhancing user functionality. This study analyzes the current status of the Construction CALS Information Disclosure System to identify its existing challenges. Subsequently, it establishes a systematic approach to the data opening process and proposes enhancements to information disclosure and search functionalities for addressing these challenges.

This study was conducted to identify dietitians' position and role by assessing the present condition on management of human resources in contracted foodservice management company. Questionnaires were distributed to 79 contracted companies (eight large-size, 48 mid-size, 23 small-size companies) from March to May in 2002. Statistical analysis was performed with SPSSwin (version 8.0). The data were analyzed in group comparisons using frequencies and percentage for every item in the questionnaires, $x^2$-test, and oneway ANOVA. About eighty-five percent of contracted foodservice companies employed the new dietitians as full time employees, and seventy-five percent of them were promoted the dietitians by evaluation after a given period of time. As a starting payment for university graduates, large-size companies payed an average of 16,260,000 won/year, which was significantly higher (p<0.01) than those of mid-sized (11,320,000 won/year) and small-sized companies (11,620,000 won/year). The mean lengths of dietitians' service were 33.5 months in large-size companies, 26.5 months in mid-sized companies, 26.0 months in small-sized companies. It was less than 3 years in all companies (avg. 26.9 months). Fifty-four companies (68.4%) employed dietitians in each foodservice contract, whereas 25 companies didn't employ dietitians. The ratios of dietitians out of employees in each department of the companies were 42.6% in the department of contracted foodservice management, 19.9% in the department of menu development, 18.1% in the department of food safety, 8.7% in the department of distribution and purchase, 4.2% in the department of business, and 3.9% in the department of customer satisfaction.

Currently many companies have realized that producing efficient product does not guarantee the market differentiation. Realizing the problem, those companies are actively pursuing the servitization strategy. However complexities in selecting the right service areas among many choices along with in developing service strategies and organizational structures remain unsolved to many manufacturing companies. This paper is about an exploratory study in which, through in-depth case analysis, we observed how a manufacturing company successfully managed to transform to the service company. Through this study, we have found that successful transformation needs to resolve many conflicting issues such as channels among existing and new sales front, organizational restructuring due to conflicting in evaluation and human resource requirements required for responding to customers in the field.

SIP(Session Initiation Protocol)-based centralized conference service model has advantage of easiness in conference management and service as compared to other models. However when media server which is one of the components of conference server is included in the conference server, this model shows disadvantage of high server work load with increasing numbers of conferences and participants. In this paper, to improve this problem, we have suggested and implemented a new conference service model in which an UA(User Agent) who first make the conference acts as a media server instead of conventional conference server and, the conference server with conference event package takes only part of management of the conference and its participants. Therefore, many more conferences can be held and managed compared to the conventional centralized conference service model because load of the conference server decreases in our suggested model md, furthermore the participants needs only make SIP call connections to the UA who first make the conference for establishing media session.

Aging educational facility shall be managed and maintained through integrated service perspectives, in consideration of functions of each facility to provide safe and comfortable environment, rather than temporarily fixing/repairing problems. For doing this, it is a must to firstly understand the limitation of highly biased performance-based maintenance practice, which is a most common type applied at present, and therefore to establish maintenance system that reflects the functions and characteristics of maintenance service that a facility was designed with. Therefore, the objective of this study is to find items that have an influence on service level recognition in order to fairly evaluate service functions of educational facilities, and subsequently to use these factors as ingredients of establishing a consistent and efficient maintenance system. Therefore this study proposed explanatory variables to measure influential factors for each major maintenance category. Then appropriate statistical verification was carried out on questionnaires that collected from a number of industry experts to test its fe asibility.
