Color reproduction is one of the most important expression factors in digital printing. In this paper, an experiment was done where the characteristics of color reproduction in digital printing. The results could summarized as follows. The printing used device profile showed a color difference of less than printing used default value in digital printing. As a result of weighting color difference, a difference between color gamut of digital original and color gamut of printing, when transforming the RGB color space to CMY color space, a exclusion the gray revision. The solution is to optimize the color transformation by gamut mapping and gray revision.

In this paper, an experiment was done where the input device used the linear multiple regression and the sRGB color space to perform a color transformation. The output device used the GOG, GOGO and sRGB for the color transformation. After the input device underwent a color transformation, a $3\;{\times}\;20\;size$ matrix was used in a linear multiple regression and the scanner's color representation of scanner was better than a digital still camera's color representation. When using the sRGB color space, the original copy and the output copy had a color difference of 11. Therefore it was more efficient to use the linear multiple regression method than using the sRGB color space. After the input device underwent a color transformation, the additivity of the LCD monitor's R, G and B signal value improved and therefore the error in the linear formula transformation decreased. From this change, the LCD monitor with the GOG model applied to the color transformation became better than LCD monitors with other models applied to the color transformation. Also, the color difference varied more than 11 from the original target in CRT and LCD monitors when a sRGB color transformation was done in restricted conditions.

시뮬레이션의 준비와 실행 및 분석과 같은 기본 기능을 제공하는 기반소프트웨어는 사용자가 시뮬레이터를 효과적으로 활용하기 위한 필수 구성 소프트웨어이다. 천리안위성 시뮬레이터는 SiMWARE 라는 기반소프트웨어를 이용하여 시뮬레이션 모델 통합을 통해 개발되었다. 본 논문은 이 SiMWARE 소프트웨어에 대해 사용자 관점에서 기능을 분석하고 이를 구성하는 컴포넌트 공동 작업구조를 설명한다. The infrastructure software which provides the fundamental functions such as simulation preparation, execution and analysis, is required to utilize the simulator effectively. COMS Satellite Simulator was developed by integrating simulation models based on SiMWARE as infrastructure software. This paper describes the functions from user’s point of view about SiMWARE and presents the collaboration interactions that show the stimuli sequence between its components.

SNUGLITE-II는 표준 3U 규격의 큐브위성으로, 누리호(KSLV-II)에 탑재된 성능검증위성과 함께 한국 시간(UTC+9) 2022년 6월 21일 16시경 발사되었다. 이후 7월 3일 16시 23분경 성능검증위성의 P-POD(Picosatellite Orbital Deployer)로부터 사출되었으며, 익일 03시 24분경 지상국 명령에 응답함으로써 최초 교신에 성공하였다. 본 논문에서는 7월 3일 사출 직후부터 12일까지 10일간 수행되었던 SNUGLITE-II 큐브위성의 운용 결과를 다룬다. 이를 위해 서울대학교 302동에 위치한 지상국과 해외 아마추어 무선사들이 운용하는 지상국을 통해 수집된 데이터와 지상국 명령으로 수집된 위성 상태정보 기록 데이터를 모두 취합하여 데이터를 시간별로 분류한다. 수집된 데이터는 SNUGLITE-II 큐브위성이 UHF 대역에서 10초 간격으로 송신하는 비콘 데이터로써, 위성의 업링크 명령, GPS 항법 정보, 전력정보, 자세제어, 센서값, 온도 그리고 식별 플래그 등의 다양한 정보를 포함하고 있다. 수집된 데이터를 통해 SNUGLITE-II 큐브위성의 위성 상태를 분석하고 탑재된 국내 개발 큐브위성용 GPS 수신기 검증과 자체 개발 자세결정 및 제어시스템의 기술적 운용 결과를 확인하였다. SNUGLITE-II is a standard 3U CubeSat that was launched on June 21, 2022, at 16:00 Korea Standard Time (KST) as a payload on the Nuri (KSLV-II) rocket. It was subsequently ejected from the picosatellite orbital deployer(P-POD) of the Performance Verification Satellite (PVSAT) at around 16:23 on July 3rd. The first communication with the CubeSat was successfully established when it responded to a command from the ground station at approximately 03:24 the next day. This paper presents the operational results of the SNUGLITE-II CubeSat, which were obtained during a 10-day period from July 3rd to July 12th. The data used for analysis were collected through the ground station located in Building 302 of Seoul National University, as well as from ground stations operated by SatNogs, a network of amateur radio enthusiasts. Additionally, satellite status information recorded by the ground station command was collected and classified chronologically. The collected data consists of beacon data transmitted by the SNUGLITE-II CubeSat at 10-second intervals in the UHF band. It encompasses various information, including satellite uplink commands, GPS navigation data, power levels, attitude control, sensor measurements, temperature readings, and identification flags. By analyzing the collected data, the operational conditions of the SNUGLITE-II CubeSat were evaluated. The performance of the domestically developed GPS receiver for the CubeSat was verified, and the technical operation results of the self-developed attitude determination and control system were confirmed.

For the correct dietary habit and balanced dietary intake of aged people, the nutrition management that fits to the dietary behavior change stage has to be accomplished. In order to do so, in this paper, we chose 175 women that are aged more than 65 years old who are rural long life community residents and surveyed the dietary intake for 2 days including a twice depth interview and the 24 hour recall method. Also, for the sake of our aim, using the transtheoretical model, the dietary behavior change stage group was divided into the contemplation stage group, the preparation stage group, the action stage group and the maintenance stage group. The results are as follows: In the intake amount of protein (p < 0.01), vitamin B1 (p < 0.05) and vitamin B6 (p < 0.05), the intake amount of these nutrients in the action stage group and the maintenance stage group were significantly larger than the intake amount in the contemplation stage group and the preparation stage group. The nutrition evaluation according to the dietary behavior change stage, the ratio of subjects who took insufficient amount of energy, protein, vitamin A, and vitamin C were low as the dietary behavior change stage was upgraded. The subjects of maintenance stage group were most likely to consume vegetables more than once a day, and consume fruits and milk and milk products more than 5 times/week. MAR [13], MAR [10] and MAR [4] of subjects in the action stage group and the maintenance stage group were significantly higher than MAR [13], MAR [10] and MAR [4] of subjects in the contemplation stage group and the preparation stage group (p < 0.001). From the above results, there were differences of nutrient intakes according to the dietary behavior change stage. Therefore, it is considered that the intervention for the dietary behavior motivation induction has to be advanced before accomplishing the individually fitting intervention at the time of nutrient management intervention.
