  • The purpose of this study was to figure out adoption of curriculum autonomy policy by a middle school. To achieve the purpose, official documents accepted or produced by the school were examined regarding how much curriculum autonomy was given to the school. As well as, minutes on curriculum organization and implementation and interviews with significant figures in the school were analyzed to reveal how the school exerted its curriculum autonomy. The results indicated that superior educational administrative institution that had made decision on curriculum autonomy policy and promoted it constantly sent to the school official documents that required it to report what had been done. Such practices prevented the school from autonomous organization and implementation of curriculum. In addition, as most decisions on curriculum organization and implementation at school level was made by administrator and teachers with special position, most teachers remained at passive status to accept what had decided by them. Parents'committee did not exercise their rights by lack of expertise and passive attitude.

  • The purpose of this study was to see teachers' perception on the School Autonomy Policy and to give some suggestions for better settlement of the policy. To achieve the above aim, we used survey method to 390 teachers and analyzed 363 responses with SPSS program. The research findings are as follows. Most of teachers supported the intent and aim of the School Autonomy Policy, however, the respondents showed conflicting responses on the contents, process, core subject according to their interests. In other words, respondents who have more teaching career including principals answered positively on the policy and it's process than lower career teachers. Lower career teachers expressed very negative recognition and little understanding for the policy itself. From the result of the survey, it could be suggested that the teachers' cooperation, especially lower career teachers' conciliation, is very important to settle down the School Autonomy Policy successively.

  • Autonomous decision-making is key to safe and efficient marine autonomy, as global marine industry comprises over 90 percent of the world's cargo transportation. Challenges of the real-world validation in the aquatic domain limits the wide-spread of ASVs despite their promising societal impacts. We propose and demonstrate the real-world validation platform and comprehensive algorithm steps. Such a framework will serve as a more explainable and reliable decision-making system of ASVs as well as autonomous vehicles in other domains.

  • The purpose of this study was to investigate the moderating effect of cultural disposition in the relationship between parenting and academic achievement. Five-hundred thirty five middle school students(male 247; female, 288) participated in this study, These students completed parenting scale and Individualism-Collectivism Scale. Academic achievement was calculated using academic scores from language, english, mathematics and science. Collected data were analyzed using multiple regression. The major findings of this study can be summarized as follows. First, parenting was significantly associated with academic achievement albeit weak. Second, influence of affective and autonomy parenting on academic achievement for both father and mother were not significant. Third, moderating effects of individualism were significant in only fathers' autonomy parenting. Fourth, moderating effects of collectivism were significant in fathers' affective parenting and autonomy parenting. These results were discussed in relation to pervious studies. Finally limitations were commented and future study were suggested.

  • The purpose of this study was to examine the relationships between perceived parental attachment and the life satisfaction of college students, focusing on the mediating role of psychological basic needs(autonomy, competence and relatedness). The Participants of this study were 208 college students. The result was statistically treated using SPSS 21.0 program, Amos 21.0. Additionally, PROCESS Macro was used to verify the significant mediating effect. Results from structural equation modeling analyses indicated that a research model produced a better fit to the data than a alternative structural model. The final SEM model fit indices of $x^2$(df), CFI, TLI, RMSEA were met the acceptable criteria of model fitness. In other words, among the goodness-of-fit indexes of the final study model, $x^2=261.075$(p<.001), RMSEA is .082, TLI equals .925, CFI equals .940. The results showed the following: First, Parental attachment has a direct effect on autonomy, competence and relatedness. Also competence and relatedness have a direct effect on the life satisfaction. Second, Competence and relatedness showed a mediating effects on Parental attachment and the life satisfaction. The implications of these results were discussed and the further studies were suggested.

  • Through the revision of the Framework Act on Administrative Regulations (July 17, 2019), the government minimized regulations and applied the comprehensive negative regulation principle to enhance economic vitality. However, a legally mandatory certification system has been applied to marine pollution prevention materials and chemicals, and inspection is conducted every time a product is sold, suppressing the autonomy of manufacturers. In addition, the majority of manufacturers of marine pollution prevention materials and chemicals are small businesses; therefore, they take the approach of producing small quantities of products whenever a buyer requests an order. Consequently, the need for deregulation was raised to ensure autonomy of the market and industry, and improve efficiency in accordance with the current trend of approval, performance test, and inspection systems for marine pollution prevention materials and chemicals. In this study, problems within the current system were identified and improvement plans are proposed through comparison and analysis of domestic and foreign systems.

  • This study was conducted to clarify a correlation among science-related attitude, overexcitability and parents' rearing attitude perceived by elementary school students. For this purpose, questionnaire surveys were carried out for 276 elementary school students consisted of 5th and 6th grades. The results were as follows. First, science-related attitude, overexcitability, and parents' rearing attitude perceived by elementary school students were meaningfully different on gender. boys'average was higher in science-related attitude than girls'. In the case of overexcitability, boys'average was higher in psychomotor and intellectual overexcitability than girls', while girls'average was higher in emotional and sensual overexcitability than boys'. According to the analysis for parents' rearing attitude perceived by elementary school students, girl students perceived that their parents more firmly controlled them as compared with boy students. Second, according to the results conducting t-test for types of parents' rearing attitude perceived by students, boy students' average was meaningfully higher in the types of love-autonomy than girl students'. There was no difference between the groups of love-autonomy type and hostility-autonomy type. Third, there showed a meaningful correlation between students' science-related attitude and parents' rearing attitude in order of love, hostility, autonomy, and control type. There showed a meaningful correlation between students' science-related attitude and intellectual, sensual, imaginational, psychomotor, and emotional overexcitability in order. Last, according to multiple regression analysis, factors effecting on science-related attitudes were intellectual overexcitability, love among the types of parents' rearing attitude perceived by students im order.

  • We are developing a biomimetic robot based on the Sea Lamprey. The robot consists of a cylindrical electronics bay propelled by an undulatory body axis. Shape memory alloy (SMA) actuators generate propagating flexion waves in five undulatory segments of a polyurethane strip. The behavior of the robot is controlled by an electronic nervous system (ENS) composed of networks of discrete-time map-based neurons and synapses that execute on a digital signal processing chip. Motor neuron action potentials gate power transistors that apply current to the SMA actuators. The ENS consists of a set of segmental central pattern generators (CPGs), modulated by layered command and coordinating neuron networks, that integrate input from exteroceptive sensors including a compass, accelerometers, inclinometers and a short baseline sonar array (SBA). The CPGs instantiate the 3-element hemi-segmental network model established from physiological studies. Anterior and posterior propagating pathways between CPGs mediate intersegmental coordination to generate flexion waves for forward and backward swimming. The command network mediates layered exteroceptive reflexes for homing, primary orientation, and impediment compensation. The SBA allows homing on a sonar beacon by indicating deviations in azimuth and inclination. Inclinometers actuate a bending segment between the hull and undulator to allow climb and dive. Accelerometers can distinguish collisions from impediment to allow compensatory reflexes. Modulatory commands mediate speed control and turning. A SBA communications interface is being developed to allow supervised reactive autonomy.

  • In this paper, a localization algorithm and an autonomous controller for PETASUS system II which is an underwater vehicle-manipulator system, are proposed. To estimate its position and to identify manipulation targets in a structured environment, a multi-rate extended Kalman filter is developed, where map information and data from inertial sensors, sonar sensors, and vision sensors are used. In addition, a three layered control structure is proposed as a controller for autonomy. By this controller, PETASUS system II is able to generate waypoints and make decisions on its own behaviors. Experiment results are provided for verifying proposed algorithms.
