To provede public services through Internet, there are several prerequisites such as security issue resolutions for public area installation and hardware support for authorized signatures etc. in addition to web-based system development. A kiosk-based system is a right solution for public services provision through Internet because a kiosk has hardware features supporting authorized signatures and also it can be installed at public area through Internet without security exposure, meeting security guidelines of National Intelligence Service. The process to provide public services through a koisk is that a client requests a kind of public services selecting menu through the kiosk, then the system issues a civil service documents after taking authentification and payment process. To support those kinds o processes it is required to support electronic payment using SMART card in addition to cash payment and to apply government standard security guidelines to protect administrative and personal information. This kiosk-based Internet public service system support and meet those all requirements.

The typical missions for the current stand-off UAVs are surveillance and reconnaissance. On the other hand, the primary mission for the future UCAS will be combat mission such as SEAD under the man-made ultimately hostile environment including SAM, antiaircraft artillery, threat radar, etc. Therefore, one of the most important challenges in UCAS design is improvement of survivability. The current studies for aircraft combat survivability are focused on the improvement of susceptibility and vulnerability of manned aircraft system. Although the survivability design methodology for UCAS might be very similar to the manned combat system but there are some differences in mission environment, system configuration, performance between manned and unmanned systems. So the parameters and their sensitivities which affect aircraft combat survivability are different in qualitatively and quantitatively. The susceptibility related parameters for F-16 C/D and X-45A as an example of manned and unmanned system are identified and the susceptibility parameter sensitivities are analyzed by using Monte-Carlo Simulation in this study.

In a traditional customer support environment, mainly call centers or service centers are responsible for receiving inquiries from their customers via telephone calls. Due to the rapid growth of Internet with its widespread acceptance and accessibility, means of communication with customers in the traditional customer support center, such as telephones, letters, and direct-visiting, have been replaced by e-mails and bulletin board systems (BBSs) using the Internet constantly. BBSs are basically question and answer systems, they require some lead time to get answer from administrator. To reduce lead time, BBSs enable remote customers or users to log on and tap into a knowledge database that is generally formatted in the form of Frequently Asked Questions (FAQs) that provide answers and solutions to the common problems. And, many different types of the questions are mixed on the BBS. It is a burden to administrator. To build FAQs and to support BBS adminstrator, a supporting tool which is to categorize questions is helpful. In this research, we suggest an interactive question categorizing methodology which consists of steps to present question using keywords, identifying keywords' affinity, computing similarity among questions, and clustering questions. This methodology allows users to interact iteratively for clear manifestation of ambiguous questions. We also developed a prototype system, IQC (interactive question categorizer) and evaluated its performance using the comparison experiments with other systems. IQC is not a general purposed system, but it produces a good result in a given specific domain.

The purpose of this study was to examine ways to improve In-Home Care Service for differences resulting from child care service and parenting stress, depending on use of the service. Participants consisted of hers from 293 who use the service in K region. From September 1, 2009 to October 25, total 193 mothers were surveyed by e-mail. 69 mothers were finally analyzed. The main results were as follows; First, the mothers got the supporting aids from two different ways, irrespective of using In-Home Care Service. One was the instrumental supports given them by their husband and relatives, and the informative and emotional supports maintained by husbands, friends, neighbors, colleagues, and network community, as well. Second, The In-Home Care Service non-users received child care support from their husbands and parents compared with the In-Home Care Service users. Third, few differences shown statistically between the two groups that use it and don't use it.

Currently memorandum have been a method to manage information easily by short writing. In particular, a electronic memorandum system has been efficiently used for business purpose, which is available in a computer widely used in our daily life. Considering the smart business environment, we propose a multi-functional electronic memorandum system in this paper, which is helpful to manage information intelligently in the smart business environment. The proposed system maintains the contents of memorandum in a database structure, so it is available without any restrictions in time and place. In addition, it also has additional functions of music playing, capturing working screens, and scheduling. The functions help for the proposed system to be widely used in the smart business environment.

We generally use SSL/TLS protocol utilizing X.509 v3 certificates so as to provide a secure means in establishment an confidential communication and the support of the authentication service. SPKI/SDSI was motivated by the perception that X.509 is too complex and incomplete. This thesis focuses on designing a secure server and an implementation of the prototype which has two main modules, one is to support secure communication and RBAC, not being remained in the SPKI/SDSI server which was developed by the existing Geronimo project and the other is to wholly issue name-certificate and authorization-cerificate. And the demonstration embodied for our sewer is outlined hereafter.
