Objectives Suicide is a complex phenomenon not only caused by the individual's mental illness and economic situation, but also occurred in sociocultural contexts and relationships around the individual. Therefore, the attitudes, which include collective norms, thoughts and feelings of a population, toward suicide play a fundamental role in the prevention of suicide. Factor structure of Attitudes Toward Suicide (ATTS), developed by Renberg, is also various in different sociocultural contexts. This is the first study to investigate factor structure of ATTS along with nationwide sample of Korean adults. Methods This study analyzed the factor structure and reliability of ATTS in 1500 regionally stratified Korean adults. Exploratory factor analysis was performed by using principal axis factoring and varimax rotation. Results The selection of 33 ATTS items based on internal consistency and communality was conducted. Five factors were analyzed, which were named 'Good reason,' 'Negative gaze,' 'Predictability,' 'Means of escape,' and 'Common secret,' respectively. Explained total variance was 41.94%, and the internal consistency ranged from 0.516 to 0.740. Conclusions Each of the five factors contains different semantic dimensions. Consistent with previous studies, factors containing permissive attitude toward suicide was high in those with history of suicidal thought and of suicide attempt. It is notable that the 'Good reason' showed higher score in elderly. This may be related to socioeconomic or physical adversities which have been considered the major cause of suicide in elderly.

In order to communicate each other we need both a system and contexts. Generally a system is called language and contexts are a common sense with a culture. If there is an absence of one of them it is impossible to understand each other. The concept of UPDP(User participating Design Process) is very similar to a communication. There must need both a system(formal tools) and a process to make consensus. Even though we already have two systems(KEBDI and PDAT) being developed by government affiliated research institutes these have not intimately related to a process to make consensus so far. In this respect the UPDP with using DQIfS of U.K. for a remodelling of Noryangjin elementary school(2013) is the most valuable because it is the first trying to communicate between laymen and professionals by menas both of a qualified system and of facilitations which have been developed from Namhansan UPDP(2001) in korea. The paper shows the process of UPDP including how to organise the members, detailed facilitation methods and the result of DQIfS analysis in U.K. Above all for the successful result the most important thing is the intimate relationship between the tool and facilitations at the beginning and user's will to build up.

The aim of this study is to look into the meaning and sub-factors of spatial orientation, compare and analyze mathematics curriculums and textbooks of several countries with respect to spatial orientation and offer suggestions to improve teaching spatial orientation in elementary school mathematics in Korea. In order to attain these purposes, this study examined the meaning and sub-factors of spatial orientation through the theoretical consideration regarding various studies on spatial sense. Based on such examination, this study compared and analyzed mathematics curriculums and textbooks used in South Korea, Singapore, Japan, China, Hong Kong, Finland, United States of America, and Germany with respect to contents of mathematics curriculum and textbooks in grades, sub-factors of spatial orientation, and contexts for spatial orientation. In the light of such theoretical consideration and analytical results, this study provided suggestions for improving teaching spatial orientation in elementary schools in Korea as follows: extending content of spatial orientation in mathematics curriculum, emphasizing spatial orientation across the several grades, especially in the upper grades, providing opportunities to learn the sub-factors of location, direction, coordinates, route, and distance variously, and utilizing various familiar and realistic contexts in the world around students.

Objectives: The purpose of this study was to suggest the strategies for improvement of home-delivered meal services for the elderly, to identify reasons for recipients to get started with the services and to evaluate the attitude, acceptability and adaptation of recipients to the services from the perspective of life context. Methods: The data was collected through face-to-face in-depth interviews with eighteen low-income elderly recipients of home-delivered meals and analyzed using a qualitative research method. Results: The results were deduced as four themes which comprised of long-term vulnerable socioeconomic contexts resulted in entry to the services, conflicting acceptability to the services, passive adaptation to taking the services, and positive practices to cope with supplement free meals or other services. The service participation was initiated because of a combination of prolonged, vulnerable socioeconomic contexts, including poverty and unexpected life events such as diseases, disability, living alone, aging and unemployment. With regard to taking the services, conflicting acceptability was observed: positive aspects including saving living cost and good quality of meals, and negative aspects including lack of a tailored service and feeling of stigma. Although the recipients needed an individualized service, they did not express their needs and demands for the services and they accepted the unavailability as an accustomed, prolonged vulnerable socioeconomic context. With regard to lack of tailored services, either self-solution such as modification of eating patterns or community-based network and services were used. Conclusions: We suggest that a system to concretely identify recipients' attitude, acceptability and adaptation for home-delivered meal services should be developed in the establishment of a tailored nutrition support system for the low-income elderly.

In the school mathematics the concept of tangent is introduced in several steps in suitable contexts. Students are required to reflect and revise their concepts of tangent in order to apply the improved concept to wider range of contexts. In this paper we consider the tangent as the optimal linear approximation to a curve at a given point and make three discussions on pedagogical aspects of it. First, it provides a method of finding roots of real numbers which can be used as an application of tangent. This may help students improve their affective variables such as interest, attitude, motivation about the learning of tangent. Second, this concept reflects the modern point of view of tangent, the linear approximation of nonlinear problems. Third, it gives precise meaning of two tangent lines appearing two sides of a cusp point of a curve.

In this paper, we propose a novel method of analyzing video and representing the relationship among characters based on their contexts in the video sequences, namely Character-Net. As a huge amount of video contents is generated even in a single day, the searching and summarizing technologies of the contents have also been issued. Thereby, a number of researches have been proposed related to extracting semantic information of video or scenes. Generally stories of video, such as TV serial or commercial movies, are made progress with characters. Accordingly, the relationship between the characters and their contexts should be identified to summarize video. To deal with these issues, we propose Character-Net supporting the extraction of major characters in video. We first identify characters appeared in a group of video shots and subsequently extract the speaker and listeners in the shots. Finally, the characters are represented by a form of a network with graphs presenting the relationship among them. We present empirical experiments to demonstrate Character-Net and evaluate performance of extracting major characters.

This paper is based on the view that film should be conceived as a form of cultural practice whose meaning is always in the process of being produced within diverse socio-cultural contexts and aims to examine the ways in which the meaning of Korean film is (re)mediated or received in diverse cultural contexts outside the country. In this paper, we employ two theoretical grounds. Firstly, it positions itself in line with the audience studies within the field of cultural studies where the audience is conceived as active agents who produce the meaning of a popular culture text. The recruitment of the theoretical propositions from the audience studies enables recognition of the significance of the reception in film practice which recently seems to be oriented on production and distribution. Secondly, we conceive transnationality of film as that which is being produced in the process of transaction between the film and the audience, that is to say, transnationality is a form of discourse that emerges upon cultural interaction. The empirical work involves examination of a set of reviews of four films--Chihwaseon, Oldboy, Thirt, Poety--that have been published in daily newspapers and some popular film magazines in the U. S., the U. K. and France. Through the analysis of the film reviews, we identify four interpretive schemes or rather discourses recruited via which the Korean films are approached and understood: auteurism, formalism, universal themes, emotional response. We propose that these four kinds of discourse provide a common ground for the audience from different cultural backgrounds to understand Korean film. Furthermore, we also suggest that transnationality of Korean cinema needs to be reconsidered in terms of the reception as the audience from different socio-cultural backgrounds should be understood as active agents who are capable of engaging in Korean cultural texts such as film in their own way producing various meanings and these are also constituent of the meaning of the cultural texts.

The purpose of this study was to investigate some implications for optics education and improvement of the Examination for Appointing Secondary School Physics Teachers (EASSPT), by analyzing the problems in EASSPT. For these purpose, we analyzed 38 optics problems of the EASSPT from the 16 school years of 2002 to 2017. The results of the analysis are as follows: First, optics problems were presented in 10.8% of the physics subject area, which was least frequently. Second, many problems have addressed specific areas such as Snell's law, image of a single lens, or interference. Few problems were found in many other evaluation areas, including optical instruments and aberrations. Third, compared to other areas, optics problems were presented as relatively easy questions, and the problems were presented in more laboratory contexts than daily-life contexts. In addition, we have discussed implications for EASSPT and in-service physics-teacher training.

In modern socity, online communication plays a vital role in social interaction of communicities. It is so common for online users to see display advertisements online while surting the Net. Specifically, most web banners diaplayed on portral sites consist of words, phrase, and sentences. Considering that the primary purpose of adversiting is persuation, the advertisement such as web banners is an examplary case to show the interaction among pragmatics, translation and advertising because the linguistic expressions employed in the banners represent its pragmatic use, leading to persuation and functioning as a communicative tool for the smooth communication between source text producers (adversisers) and target audience (online users). This can be part of the so-called translation process. In particular, we can easily witness the use of English words in web banners. Thus, this paper looks at web banners displayed on major four portal sites-Naver, Daum, Nate, and Zum, giving a special attention to the content contained in the web banners as well as the use of English words. As s result, we found that the frequencies of English words in each portal site were higher when the advertised products were targeting young online users, whereas the frequencies were lower when the users are older group than young people. The finding supports the prgramatic perspective that linguistic expressions are understood in social contexts and shows the so-called translation process which involves a shift from semantic meaning of words to their pragmatic use. Finally, we can conclude that the interaction is possible when we have the framework where translation, pragmatics, and advertising are all communitative components for social interaction within social contexts.

Previous studies on double scale models, visual models with two different scales (Chong, 2015), have focused on double number line and little research has been conducted on how to employ double scale models in the elementary mathematics textbooks series. Given this, we analyzed the characteristics of double scale models in the Japanese elementary mathematics textbooks in the following aspects: (a) the contents of units where double scale models were used; (b) the purposes of using such models; (c) the types of such models tailored to the contents and grade levels; and (d) the characteristics of problem contexts dealing with the models. The results of this study showed that double scale models were effectively used to connect the contents related to multiplication, specifically for the contexts of ratio. Such models were addressed for students in a systematic and gradual way as the grade levels went up. Based on these results, this paper describes implications on how to use double scale models in mathematics textbooks.
