The purpose of this study is to provide a solution through a methodological approach so that character education can be naturally acquired in team-based learning activities. In the spring semester of 2021, a total of 69 college students in two groups were studied, and as a result of the study, the total score of character education virtues in the post-test was greatly improved in the experimental group (p<.001). The correlation between sub-items of team-based learning and pre and post-test results for character sub-items, self-regulation, consideration, communication, self-esteem, and responsibility, were statistically significant. This study shows character education through team-based learning had positive results. However, future research through a wider range of subjects is needed, and various teaching methods are being applied to propose verification of the effectiveness of character education.

The purpose of this study is to recognize the importance of 'character', which is an important keyword in the era of the 4th revolution, and to approach the teaching method through the life of Haydn and his music among various methods of character education. The purpose of this study was to investigate the research hypothesis that the convergence education of music and character brings positive changes in pre-and post-recognition of sub-elements of character virtues. As a research method, character education was conducted through class activities using Haydn's life and music for a total of 6 times. The result shows the change in pre-and post-cognition of sub-elements of personality virtues, and statistically significant (p<0.01) in all virtues of character education. Activity-oriented classes through the life and music of a composer were worthy for the effective character education. A further study would be meaningful by applying various teaching activities if the scope of study is expanded.

We propose a character recognition system to extract the component reference names from printed circuit boards (PCBs) automatically. The names are written in horizontal, vertical, reverse-horizontal and reverse-vertical directions. Also various symbols and figures are included in PCBs. To recognize the character and orientation effectively, we divide the recognizer into two stages: character classification stage and orientation classification stage. The character classification stage consists of two sub-recognizers and a verifier. The rotaion-invarint features of input pattern are then used to identify the character independent of orientation. Each recognizer is implemented as a neural network, and the weight values of verifier are obtained by genetic algorithm. In the orientation classification stage, the input pattern is compared with reference patterns to identify the orientation. Experimental results are presented to verify the usefulness of the proposed system.

The electromagnetic (light) waves are limited to penetrate the media, ie, water and sea-bottom layers, due to high energy attenuation, but acoustic (sound) waves play as the good messenger to gather the underwater target information. Therefore the acoustic methods are applied to almost of ocean equipments and technology in terms of in-water and sub-bottom surveys. Generally the sound character is controlled by its frequency. In case that the sound source is low frequency, the penetration is high and the resolution is low. On the other hand, its character is reversed at the high frequency. The common character at the both of light and sound is the energy damping according to the travel distance increase.

Nowadays, many people enjoy playing games in computer. In this kind of game, people often meet NPC (Non Player Character). It is the virtual character in simplified form of real player and exits in most of current computer games. Various NPCs add the reality and atmosphere of the game as well as help players. There are several techniques to embody NPC, but developers generally use AI technique. This paper discusses some artificial intelligence techniques used in game contents. Especially this paper focuses on the AI techniques used in computer games in terms of the two main approaches, symbolic approach and sub-symbolic approach.

The purposes of this study were to compare elementary gifted students with general students in respect of their character strengths, emotional intelligence and learning flow and to analyze the relationships. The results obtained in this study were as follows. First, the character strengths, emotional intelligence, and learning flow of the gifted students were higher than those of the general students. Humanity was the highest virtue for both gifted and general students. Gifted students showed a significantly lower mean difference in humility and modesty than that of general students. The gifted students showed a statistically higher mean value in the sub-regions of emotional intelligence and all sub-areas of the learning flow than that of the general students. Second, the strong correlations were found between character strengths and emotional intelligence, between character strengths and learning flow in gifted students. Third, the results showed that the character strengths of gifted students affected their emotional intelligence and learning flow significantly.

A sample of soil humic acid (HA) was divided by ultrafiltration (UF) into five fractions of different molecular size (UF₁: > 300, UF₂: 100~300, UF₃: 30~100, UF₄: 10~30, UF₅: 1~10 kilodaltons). Apparent average molecular weight (M_w) of the HA fractions were measured using high performance size exclusion chromatography (HPSEC), and the chemical and structural properties of the five HA fractions were characterized by elemental compositions (H/C, O/C and w ((2O + 3NH)/ C)) and ultraviolet-visible absorption ratios (SUVA, A_4/6). The organic carbon normalized-sorption coefficients (Koc) for the binding of phenanthrene to the HA fractions were determined by fluorescence quenching and relationship between the sorption coefficients and structural characteristics of the HA fractions were investigated. The elemental analysis and UV-vis spectral data indicated that the HA fractions with higher molecular weights have grater aliphatic character and lower contents of oxygen, while the HA fractions with lower molecular size have greater aromatic character and molecular polarity that correspond to greater SUVA and internal oxidation values (w). The log Koc values (L/kg C) were gradual increased from 4.45 for UF₅ to 4.87 for UF1. The correlation study between the structural descriptors of the HA fractions and log Koc values of phenanthrene show that the magnitude of Koc values positively correlated with $M_w$ and H/C, while negatively correlated with the independent descriptors of the O/C, w, SUVA and A_4/6.

The purpose of this study is to examine the previous literature in home economics and contents and achievement standards of 2009 revised curruculum in relation to character education. To achieve this purpose 1) the literature review in human development and family, self-management and consumption life, food, clothing, and housing life area is critically discussed in relation to character education, and 2) curriculum contents and achievement standards are analysed in relation to the six pillars(trustworthiness, respect, responsibility, fairness, caring, and citizenship) of character education proposed by Josephson Institute. The results of analysis are verified by five experts in home economics content areas. Specific results of relation between home economics contents/achievement standards and six elements of character education are as follows. Human development and family area is most closely related with all elements of character education among other content areas. In Self-management and consumption life areas, self-management sub-area is very closely related with responsibility element; and consumption life sub-area is very closely related with citizenship element. In food area, health diet and eating sub-area is very closely related with trustworthiness, respect, and responsibility elements; and eco-frendly diet and food sub-area is very closely related with all six elements.

Heterostructures fabricated by various combinations of van der Waals (vdW) materials enable us to investigate disorder-free physical properties and realize novel functional devices. Superconducting vdW junctions have attracted a lot of attention because of its simple structure without a barrier layer. In superconducting vdW junction, without extra fabrication effort, a natural barrier can be formed, whose character is sensitive to distance and angle of lattice between two superconducting vdW materials. Using high-quality single crystals and the dry transfer technique, we fabricated the vertically stacked NbSe₂/NbSe₂ and FeSe/FeSe vdW junctions and investigated their Josephson junction properties. We found that in the FeSe junctions, Josephson coupling is extremely sensitive to the fabrication conditions, in contrast to the NbSe₂ junctions. We attributed this distinct character of the FeSe junctions to surface instability and small Fermi surface of FeSe.
