The purpose of this research is to investigate characteristics of science content knowledge and pedagogical content knowledge shown in the primary school science classes. Through analysis of classroom teaching, explore the features and differences between primary and secondary school science PCK. Using open-ended interviews with the teachers and group discussions on a regular basis to analyze and compare classes of five primary school teachers, the relationship between CK and PCK. Regardless of the school level the teacher's PCK and professionalism is required with varying focus and emphasis. The features of the primary school teacher's PCK are as follows: Firstly, elementary teach secondary teach content, teachers value pedagogical knowledge (PK) content knowledge (CK). The primary school PCK requires more of understanding of students and teaching methods that to subject areas. PCK be without content knowledge, and the teacher's PCK is subject-specific In addition to the characteristics of PCK in the primary school science teaching, ways to set up professional exchange or collaboration between primary and secondary teachers, and to provide supplementary in-service training focused on content knowledge for primary school teachers.

As customers' participation in B2C e-commerce increases, customers are getting more involved in the delivery of services, which may even go beyond the completion of service transactions. To examine such proactive extra-role online customer behavior, we delve into organizational citizenship behavior framework, which has been recently extended to examine customer citizenship behavior (CCB) in the service market area. Although CCB is vital for online retailing success, MIS and e-commerce research efforts have generally focused on the customer's customer coproduction that are customer in-role behaviors. Moreover, although the effect of information created by anonymous strangers on other customers increase, interpersonal trust research have focused on only the relationship between a seller and a customer. Therefore, this study attempts to answer two research questions: What are motivational factors that affect CCB? How differently do the two kinds of interpersonal trusts (trust in online retailer and trust in customers) influence customers?

The practice named "Creative Design and Production" has been given to train the students'ability to find and solve problems. Students are expected to design and fabricate creative artifacts in the practice. The practices focusing on perfection and creativity of the products have been executed for the past few years. We have reviewed the relationships between these abilities and the qualities of products of the students in the practices. It seems that the products lacks of originality and creativity when focused on the perfection. And on the contrary, the perfection of the products is low when focused on the creativity. We have employed the new three trials in order to solve these problems in the practice. Among trials, the cooperation with veterans has been the most useful for students through "Creative Design and Production".

The purpose of this study is to investigate the relationships between elementary school teachers' points of view about the organization of the science curriculum and their views on the nature of science (NOS). We surveyed 132 elementary school teachers' view points about these two kinds of views, analyzed the data by their variables, and compared the two viewpoints with their personal details. The elementary school teachers thought the science curriculum should be emphasized through the process more than contents. They thought the contents of the science curriculum should be integrated rather than separated. As teachers' career progressed, they focused on the contents more than the process. On the other hands, because elementary school teachers showed the NOS views as relativism, deductivism, decontextualism, content, and instrumentalism, when we plotted sub-viewpoints of NOS in process-content dimension, we thought it would be similar distributions with point of views on the organization of science curriculum. However, there was no meaningful relation. This showed that teachers' views on the organization of the curriculum and the NOS are totally different. These findings suggest further research is needed to find how factors influence elementary school teachers' views on the organization of the science curriculum and what inclinations can occur in science classes with their different views.

The results of the analyses of 431 doctoral disserations of science education (Dissertation Abstracts International. 1980-1984) are as follows : 1. It was recognized that many countries as well as USA(e.g. Canada, Nigeria, Saudi Arabia, South Africa, Taiwan, Thailand, The Netherlands etc.) have deep interest in science education. 2. About 60% of dissertations had been focused on middle school (junior and senior)and college students as the subject of investigation. 3. Disciplines of science concerning the subject showed general science (35.6%), biology (18.3%), physics (11.4%), chemistry (11.4%), earth science (4.6%), and others (18.7%). 4. The number of dissertations belonging to experimental research was over 60 more than that of dissertations belonging to theoretical research. 5. In methodology of research, examination, test, questionaire were general method, and the field of research was focused mainly on the academic achievement.

As interest in the metaverse has grown, there has been a demand for avatars that can represent individual users. Consequently, research has been conducted to reduce the time and cost required for the current 3D human modeling process. However, the recent automatic generation of 3D humans has been focused on creating avatars with a realistic human form. Furthermore, the existing methods have limitations in generating avatars with imbalanced or unrealistic body shapes, and their utilization is limited due to the absence of datasets. Therefore, this paper proposes a new framework for automatically transforming and creating stylized 3D avatars. Our research presents a definitional approach and methodology for creating non-realistic character avatars, in contrast to previous studies that focused on creating realistic humans. We define a new shape representation parameter and use a deep learning-based method to extract character body information and perform automatic template mesh transformation, thereby obtaining non-realistic or unbalanced human meshes. We present the resulting outputs visually, conducting user evaluations to demonstrate the effectiveness of our proposed method. Our approach provides an automatic mesh transformation method tailored to the growing demand for avatars of various body types and extends the existing method to the 3D cartoon stylized avatar domain.

In-situ transmission electron microscopy (TEM) holders that employ a chip-type specimen stage have been widely utilized in recent years. The specimen on the microelectromechanical system (MEMS)-based chip is commonly prepared by focused ion beam (FIB) milling and ex-situ lift-out (EXLO). However, the FIB-milled thin-foil specimens are inevitably contaminated with Ga⁺ ions. When these specimens are heated for real time observation, the Ga⁺ ions influence the reaction or aggregate in the protection layer. An effective method of removing the Ga residue by Ar⁺ ion milling within FIB system was explored in this study. However, the Ga residue remained in the thin-foil specimen that was extracted by EXLO from the trench after the conduct of Ar⁺ ion milling. To address this drawback, the thin-foil specimen was attached to an FIB lift-out grid, subjected to Ar⁺ ion milling, and subsequently transferred to an MEMS-based chip by EXLO. The removal of the Ga residue was confirmed by energy dispersive spectroscopy.
