A High-degree Cubature Kalman Filter (CKF) is proposed to deal with the Strapdown Inertial Navigation System (SDINS) alignment problem. In-flight Alignment (IFA) is an effective method to compensate for attitude errors of the navigation system. While providing precise attitude error compensation, however, the external source aided alignment often creates a nonlinear filtering problem caused by a large misalignment angle. Introduced recently, Cubature Kalman Filter is a suitable technique for various nonlinear problems. In this paper, a higher degree CKF is applied to this accuracy-is-everything SDINS IFA problem. The simulation results show that the proposed technique outperformed a traditional nonlinear filter in terms of precision and alignment time.

본 논문에서는 DACS(Divert and Attitude Control System)를 장착한 KV(kill vehicle)의 비선형 가속도 조종루프 설계에 대해서 다룬다. ACS(Attitude Control System)는 받음각을 0으로 유지시키는 추력을 유발시키며, 받음각 제어를 위해 ACS를 제어명령으로 사용하는 궤환선형화 기반 비선형 받음각 조종루프를 제안한다. 받음각이 0인 조건에서는 비행경로각과 자세각이 일치하기 때문에 DCS(Divert Control System)는 유도루프에서 요구하는 측방향 가속도를 직접 생성하도록 제어한다. 이러한 방식에서는 추력에 의한 공력간섭 효과를 최소화 시킬 수 있으며, DCS와 ACS의 운용로직을 단순화 시킬 수 있다. 수치 시뮬레이션을 통해 제안한 기법의 성능을 검증한다.

This study was undertaken to investigate the general attitude toward science and scientific inquiry behavior of underachiever at the junior high school level. In this study, underachiever was defined as the one who is below the minimum acceptable performance level because of his/her deficiencies in prerequisites but who has the capability to reach the required mastery level in normal classroom. For the identification of the underachiever, IQ test and achievement test in science which were developed by the investigators were used. The attitude test which was to measure the general attitude toward science and scientific inquiry behaviors of the underachiever was also developed by the investigators. The tests were given to 250 1st grade junior high school students in one experimental school. Out of 250, 55 underachievers were identified. For the study, 55 underachievers with 57 normal students were compared. The findings of this study showed that there were significant differencies between underachievers and normal students in both attitude toward science and scientific inquiry behavior. They can be summarized as follows; 1. Awareness on science by underachievers was minimal compared to normal students. 2. Compared to normal students, there was a tendency by underachievers to think the influence of science on their real life is remote. 3. Underaschievers were less positive, less voluntary and were less persistent in science activities than normal students. 4. Underachievers were less interested in science than normal students. These findings showed us that there were significant relation between the attitude and achievement level. This suggests that fostering attitude toward science and scientific inquiry behavior is needed for the improvement of achievement level of underachievers.

This study aims to investigate whether financial attitude links financial literacy to financial capability. To make sound financial decisions, one essentially requires a certain level of financial literacy - knowledge and skill in finance. Even more effective is when one's financial literacy could be developed into financial capability. The samples comprised 342 individuals from informal labor in the South of Thailand. The stratified multistage sampling technique was utilized to select the respondents, while the interview questionnaires were used to collect the data. By using SmartPLS 3.0, the data analysis included descriptive statistics and structural equation modeling (SEM). The result revealed that the one with the highest debt was Gen Y compared to Gen B and Gen X. Considering financial literacy, financial attitude, and financial capacity across generations, it was found that Gen Y had the highest average score in financial literacy and financial capacity, higher than that of Gen X and Gen B. The impact of financial literacy on financial capability through financial attitude, it was found that the impact on Gen B was higher than that of Gen X and Gen Y. With the right financial attitude, people of all generations would be equipped with a higher level of financial capability.
