Opis:
We synthesized the uniform monoclinic gallium oxide (Ga$\text{}_{2}$O$\text{}_{3}$) nanobelts by a simple thermal annealing of GaN powders. The as-syn-thesized nanobelts were rectangular in cross-sectional shape with width ranging from 100 to 700 nm. The length direction of the nanobelt was along [010]. Photoluminescence measurement under excitation at 325 nm showed that the Ga$\text{}_{ }$2O$\text{}_{3}$ nanobelts had a blue emission at around 454 nm.

Opis:
The current curricula of the departments of Chinese in Korea emphasize language and literature, although most students in these departments would prefer an emphasis on curricula in the Chinese social sciences, with less emphasis on language and literature. The research reported here include surveys that identified needs as perceived by students, and contrasted these with studies of existing Korean departments of Chinese. This research indicates that Korean universities currently lack the ability to meet students’ needs. For more effective education, Chinese departments should offer two-track curricula, consisting of a language track and a social science track.

Opis:
To derive a more effective educational method, racial differences among Chinese students in learning Korean culture was invesigated using a survey method. The Han and Joseon racial groups in China were examined. Before the survey, the Han race students (Chinese students except Joseon race students, in this case) preferred a language and culture teaching method (LCTM), whereas the Joseon race students favored an audiovisual teaching method (AVTM). However, after experiencing four different teaching methods – comparative-cultural teaching method (CCTM), AVTM, LCTM, and rote memorization teaching method—for two weeks, the Han race students preferred the AVTM more, whereas the Joseon race students preferred the CCTM. Thus, students from the same country require different education methods.

Opis:
The objective of this research was to find a more effective method for the teaching of history to Chinese students studying in South Korean universities. Questionnaire surveys and interviews were conducted to investigate those students’ level of knowledge and perceptions of Korean history. Then, in history classes, four teaching methods (comparative-historical, audiovisual, history and language, and rote memorization) were applied over two weeks. Before the treatment, Chinese students said that they liked the audiovisual teaching method the most, but after taking the classes, they preferred the teaching method comparing Korean and Chinese histories. Besides the finding that the comparative method was the most popular, the responses also showed that it was the most effective one in teaching history to Chinese students.

Opis:
This study aims to prepare the most effective Korean history education plan for children from mixed marriages in Korea using a questionnaire survey and in-depth interviews. Before the survey, the children from mixed marriages between Korea and Vietnam, China, and Japan preferred the auto-visual teaching method (ATM). However, after learning Cramming Teaching Method (CTM), Audio-Visual Teaching Method (ATM), Comparative-History Teaching Method (CHTM), and Discussion Teaching Method (DTM) for one week, Chinese and Korean – Japanese children preferred CHTM, whereas Korean-Vietnamese children preferred ATM itself. Hence, CHTM was found to be the most effective method when educating Korean history to the children from mixed marriages between Korea and countries with many historical conflicts, similar to that of their mothers (first-generation immigrants).

Opis:
NdFeB anisotropic sintered permanent magnets are typically fabricated by strip casting or melt spinning. In this study, the plastic deformability of an NdFeB alloy was investigated to study the possibility of fabricating anisotropic sintered magnets using gas atomized powders. The results show that the stoichiometric composition Nd12Fe82B6 softens at high temperatures. The aspect ratio and orientation factor of Nd12Fe82B6 billets after plastic deformation were found to increase with increasing plastic deformation temperature, particularly above 800°C. This confirms that softening at high temperatures can lead to plastic deformation of Nd2Fe14B hard magnetic phases.

Opis:
In this study, we propose a cooling structure manufactured using a specialized three-dimensional (3D) printing design method. A cooling performance test system with complex geometry that used a thermoelectric module was manufactured using metal 3D printing. A test model was constructed by applying additive manufacturing simulation and computational fluid analysis techniques, and the correlation between each element and cooling efficiency was examined. in this study, the evaluation was conducted using a thermoelectric module base cooling efficiency measurement system. The contents were compared and analyzed by predicting the manufacturing possibility and cooling efficiency, through additive manufacturing simulation and computational fluid analysis techniques, respectively.
