질 높은 모바일 게임을 단시간에 개발하기 위해서 예전에 PC에서 인기 있었던 게임을 모바일용으로 재개발하는 경우가 많아지고 있다. 모바일의 플랫폼이 통일화되어 있지 않은 지금 PC의 게임을 모바일로 변환하는 작업을 플랫폼 별로 개별 개발을 하여야 하는 문제점을 갖고 있으며 이러한 중복되는 작업을 최소화하기 위해서 규정된 내용의 변환 테이블을 이용하여 자동으로 변환 작업이 가능하도록 하고자 한다. 아바타 변환기는 상의한 모바일 플랫폼에서 사용되는 프로그램 구조와 API로 구성된 변환 테이블을 가지며, 변환 테이블을 기준으로 변환하고자 하는 플랫폼에 동작하는 모바일 게임 프로그램을 재 생성해 낸다 이로 인하여 PC의 게임을 모바일 게임으로 변환하는 작업이 하나의 플랫폼으로 개발을 완료하면 다양한 플랫폼에서 서비스 가능하게 될 것이다

In Boundary Point Coordinate Register Area, the accuracy on Transformation of World Geodetic System(WGS) is determined by surveying results at the reference point. However, the present surveying result in reference points indicates the irregular performance due to the limitations of measurement techniques and methodologies, moreover, can be contaminated by various error sources from the unique characteristics of each project district and start time of the project. Therefore, the main purpose of present investigation is to conduct an inquest into error cause by project districts for each type in Boundary Point Coordinate Register Area, and propose the improvement plan of surveying accuracy through the WGS Transformation and verification-surveying.

The construction standards in Korea consist of design standards and specifications. They are provided by the national transportation electronic information center in file format, not in a DB, which may lead to their incomplete utilization and versatility, such as a lack of history management and reference functions. This also makes it difficult to cross-refer to standards and manage revision history. In this study, we developed a code management system for the national construction standards by analyzing domestic and overseas related systems, in order to pinpoint the problems in the current system and its development direction and, thus, to suggest a detailed plan for the design and implementation of a code management system. The developed system comprises four subsystems, namely a construction standards making system, construction standards service system, construction standards maintenance system and construction standards portal system. The results of this study are expected to improve the user's convenience by facilitating the revision, operation and history management of the complex and various construction standards, and to provide high-quality national construction standards by effectively supporting the revision and operation of the national construction standards with minimum duplication and conflicts.

In this paper, we describe the color reproduction system for color images captured by digital camera. The system uses a color compensation chart to estimate the transformation between the colors in the image and the reference colors in the chart. The color reproduction process consists of two steps, i.e., the profile creation process and the profile application process. During the pro-file creation process, the relationships between the captured colors and the ref-erence colors are estimated. And the system creates a color profile and embeds the estimation result in the profile. During the profile application process, the colors in the images which are captured under the same condition as that of the chart image are reproduced using the created color profile. To evaluate the per-formance of the system, we perform experiments under various conditions. And we compare the results with those of widely used commercial applications.

The mobile electronic notice service (MENS) is a service that delivers a mobile electronic notice to a smartphone in the person's name through an authorized electronic document intermediary instead of a bill that was delivered by mail using paper. In order to provide the MENS, information is needed to identify the same user between the sending agency and the authorized electronic document relay. In this paper, we propose a standard for safe conversion and utilization of Connecting Information (CI) used as user identification information for MENS. In the proposed method, it is necessary for the requesting institution to send the electronic notice to provide the resident registration number to the identity verification institution and convert it into the CI. In this case, a safe and efficient MENS will be possible by proposing a review standard and processing method to verify the appropriateness of the conversion of CI. By applying the proposed method to the MENS, it can contribute to service activation and reinforcement of user privacy protection.

On the new medical system separating the prescription and dispensing of the drug, the qualification of pharmacist in substitution of prescribed medicine was restricted, except bioequivalence-certified drugs. Also, Korean Food and Drug Association(KFDA) revised the bioequivalence regulation on August, 2001 Among many changes from old guideline, impressive one is the statistical consideration. Specially, to estimate and analyze bioequivalence measures, AUC and $C_{max}$, the log-transformed model is recommended and the equivalence interval is modified from $\pm$20 rule to [In(0.8),In(1.25)] one. This meaningful act is very hope-for because it is statistically reasonable and is agreed with worldwide bioequivalence guideline, including USA, EU, Japan and Canada. In this paper, we introduce the new regulation of assessing bioequivalence, announced at August, 2001, mainly on statistical view points. Key points for the new regulation are discussed and the minimum sample size based on simulation studies are proposed.

'UFO2MF' and 'Korean MetaFont Generator' have been developed to convert UFO codes to the corresponding Metafont codes by using outline editing methods. However, 'UFO2MF' cannot express smooth curves because it use only reference points without using control points. And 'Korean MetaFont Generator' can easily design the curve of characters, and supports Hangul characters, but this system does not support Roman characters. In this paper, we propose a UFO2xMF system, which can convert both Korean and Roman characters from outline text information into Metafont codes. UFO2xMF can apply attribute values which can change the shape of letters during the conversion of Metafont code. It is also a highly compatible system that can convert the characters of various languages not only Korean characters but also Roman and other characters into Metafont codes by applying letters with baseline and centerline of gravity.

Ground control points are needed for precision geometric correction of satellite images, and the coordinates of a high-quality ground control point can be obtained from the GPS measurement. However, considering the GPS measurement requires an excessive amount o f t ime a nd e fforts, there is a need for coming up with an alternative solution to replace it. Therefore, we examined the possibility of replacing the existing GPS measurement with coordinates available at online maps to acquire the coordinates of ground control points. To this end, we examined error amounts between the coordinates of ground control points obtained through Daum Map API, and them compared the accuracies between three types of coordinate transformation equations which were used for geometric correction of satellite images. In addition, we used the coordinate transformation equation with the highest accuracy, the coordinates of ground control point obtained through the GPS measurement and those acquired through D aum M ap A PI, and conducted geometric correction on them to compare their accuracy and evaluate their effectiveness. According to the results, the 3rd order polynomial transformation equation showed the highest accuracy among three types of coordinates transformation equations. In the case of using mid-resolution satellite images such as those taken by Landsat-8, it seems that it is possible to use geometrically corrected images that have been obtained after acquiring the coordinates of ground control points through Daum Map API.

반도체 패키지 제조공정 중에는 제품에 일련번호를 인쇄하는 마킹공정이 있다. 마킹 공정에서 새겨진 문자는 해당 관리기준에 따라 관리되고 있는데 최근 반도체 패키지의 소형화에 따라 인쇄된 마크문자의 틀어짐 정도가 관리기준에 미달되는 문제가 발생되고 있다. 본 논문에서는 마크문자의 검사 항목 중 tilted mark(angle mark) 검사를 위한 회전량 측정방법으로 golden section searching 방법을 적용한 고속 라돈 변환(radon transform)방법을 제안한다. 실험에서는 제안한 방법이 일반적인 라돈 변환에 비해 최대 약 21 배의 회전량 측정속도가 향상되는 것을 확인하였다.
