This study is designed to help pre-service teachers to improve their teaching skills in elementary math class. For this, the consulting program with 5-steps was planned and applied to three elementary pre-service teachers. Each class the teachers performed was analyzed by both Flanders's Interaction Analysis Category System and participant observation. As results of consulting, the common characteristics of three pre-service teachers are shown. Firstly their teaching style is non directive, but they fail to induce their students spontaneously respond. They often ignore or don't use their students' respond they think incorrect to develop the next ideas. Simply saying, their classes are typically teacher-oriented but they are not authoritative. It is proved that consulting program is effective for improving developing non directive teaching skills, but is not much effective decreasing teachers' comment and increasing students' rolls in a math class.

An ad endorser's gaze direction is a salient nonverbal cue that consumers use in responding to advertisements. The gaze direction influences consumers' social perceptions (e.g., attractiveness, credibility) of the endorser and advertising effectiveness (e.g., advertising attitudes, brand attitudes). Especially, the cerebral emotional asymmetry hypothesis suggests that an ad endorser's left-averted gaze can produce more positive social perceptions and advertising effectiveness than the right-averted gaze for right-handed consumers. This study examined the effects of three gaze directions (direct, left-averted and right-averted gaze directions) of unknown female ad endorser on Korean males' advertising responses (attractiveness-, credibility- and ad-effectiveness-related responses), using online experimental method. The results indicated that the ad endorser's direct gaze was more likely to increase both positive (correspondence bias) and negative (suspicion, deceptiveness) social perceptions of her than the right-averted gaze. The direct gaze also created more positive advertising effectiveness (advertising attitudes) than the right-averted gaze. However, the study failed to find consistent differences in responses between left-averted gaze and either direct or right-averted gaze.

For an application of ontology, query processing is mandatory field for efficient information search in the ontology. Other query processing systems tend to analyze only facts and to simply provide structural information for users. In fact, the systems do not have big difference with database systems or text based information processing systems. Therefore, in this research, the method which can provide the inferred information based on axioms is suggested in order to maximize reusability of ontology.

인터넷의 발달은 전통적인 자연 발생적인 시장에 의한 상거래를, 기술에 의한 안전하면서 세계 시장을 쉽게 접근할 수 있는 전자상거래 구조를 제공하고 있다. 현재 전자상거래의 대상은 실물에 대한 상거래와 디지털 컨텐츠에 대한 상거래로 크게 분류할 수 있으며, 실물에 대한 상거래는 전통적 상거래 방식이 컴퓨터로 바뀐 상황이라고 볼 때, 디지털컨텐츠에 대한 상거래 즉, D-Commerce에 대한 상거래의 개념이 도래하고 있다. 디지털 컨텐츠의 상거래에 필요한 요소 기술에 대한 연구, 그리고 특히 새로운 유통 비즈니스 모델에 대한 연구가 필요하다. 디지털 컨텐츠는 생성, 가공, 유통, 분배 둥의 측면에서 많은 장점을 갖는 반면, 복사를 여러 번해도 원본의 품질에 손상 없이 쉽게 복사 될 수 있다는 것이 디지털 저작권 보호에 커다란 문제점으로 대두되고 있다. 디지털 저작권권리(Digital Rights Management: DRM)은 디지털 콘텐츠의 보호와 적절한 유통체계를 설립하여 안전하게 상거래를 할 수 있게 하기 위한 새로운 기술이다. XrML은 권리(Right)를 명시하는 언어로써 디지털 컨텐츠와 그에 따른 서비스들을 사용할 수 있는 권리와 조건들을 명시해준다. XrML은 현재 디지털 저작권권리(Digital Rights Management: DRM)에 가장 많이 쓰이고 있는 Rights Language이다. XrML은 ContentGuard가 개발한 DRM 서술 언어로 전 세계 산업계 표준으로 추진하기 위하여 파트너 회사 확대, 기능 확장, 무료/공개 형식으로 보급을 추진하고 있다.

Component-based software engineering (CBSE) composes reusable components and develops applications with the components. CBSE is admitted to be a new paradigm that reduces the costs and times to develop software systems. The high quality of component designs can be assured if the consistency and correctness among the elements of a component are verified with formal specifications. Current formal languages for components include only some parts of contracts between interfaces, structural aspects and behavioral aspects of component, component-based system, component composition and variability. Therefore, it is not adequate to use current formal languages in all steps of a component design process. In this paper, we suggest a formal language to specify component designs Component-Z. Component-Z extends Object-Z, adds new notations to specify components. It can be possible to specify interfaces, the inner structure of a component, inner workflows, and workflows among interfaces with Component-Z. In addition, Component-Z provides the notations and semantics to specify variability with variation points, variants and required interfaces. The relation between interfaces and components is defined with mapping schemas. Parallel operator is used to specify component composition. It can be possible to describe deployed components with the specifications of component-based systems. Therefore, the formal specification language proposed in this paper can represent all elements to design components. In the case study, we specify an account management system in a bank so that we show that Component-Z can be used in all steps of component design.

Purpose: This study aims to analyze the meaning of architectural space of Alvar Aalto, which is based on architectural theories of periodic flows and the form of the space with the various elements applied to the works. Method: It analyzes the interrelationships of light, form and material in triangular composition by synthesizing the architectural vocabulary of Alvar Aalto from the viewpoint of modernism. Results: The architectural works of Alvar Aalto are centered on the combination of light, form, material, and space diversity, emphasizing social awareness and linking the human scale with the building environment. Conclusion: The structure of the Alvar Aalto is a synonym of nature and culture, society and individuals, standardization and diversity, universality and locality, intellectual and emotional, scientific and human psychological. It is possible to apply reciprocity elements to architectural spaces in a comprehensive manner while being different from each other in terms of rationality and immediacy.

In physics education, language is an fundamental learning tool as in other subjects. In writing activity, students can get fair opportunities to express their own ideas during the class. Even though there are various styles of writing, students are usually supposed to make a report in their science classes. But there have been few studies in science education on the tasks and features of student's science writing. In this research, different styles of writing tasks were designed for science classes, and students' writing was analysed in terms of conceptual and emotional aspects. Also the usefulness of each task type was discussed relating to school physics education. Four types of writing, i.e. , , , and writing were developed, and 'The reflection of light' was selected as the theme and given to students. Four types of writing were analysed in this paper. In each type of writing, students showed different features in their conception. They also showed emotional expressions in imaginative writing types, that is, and types. Based on these results, it is recommended that in physics teaching various types of writing need to be designed, developed and applied according to the aim of a particular lesson.

Recently, Golang has been gaining attention in programming language rankings each year due to its cross-compilation capabilities and high code productivity. However, malware developers have also been increasingly using it to distribute malware such as ransomware and backdoors. Interestingly, Golang, being an open-source language, frequently changes the important values and configuration order of a crucial structure called Pclntab, which includes essential values for recovering deleted symbols whenever a new version is released. While frequent structural changes may not be an issue from a developer's perspective aiming for better code readability and productivity, it poses challenges in cybersecurity, as new versions with modified structures can be exploited in malware development. Therefore, this paper proposes GoAsap, a detection and analysis system for Golang executables targeting the new versions, and validates the performance of the proposed system by comparing and evaluating it against six existing binary analysis tools.
