Education for Sustainable Development is an imperative mean to achieve the sustainable development which is the key idea that meets the needs of both present and succeeding generations by reconciling environmental protection, social development and economic growth. This study addressed the following question. First, what is the overall structure of the ESD contents presented in the textbooks? Second, How are the sub-contents of ESD distributed in the textbooks? Lastly, How are the ESD contents connected to mathematics in the textbooks? For this purpose, the contents in the elemtentary mathematics textbooks from 1^st to 6^th grades were analyzed at both macro and micro levels through quantitative and qualitative research methods. As results, contents related to environmental, social, and economic dimensions were presented from the first grade. The contents were involved the mathematics content domains of Numbers and Operations, Data and Possibilities, and Patterns. However, the contents were presented intensively in middle and high grades, and environmental topics accounted for a high proportion. Among the activities related to ESD, many were focused on solving problems mathematically while some were presented to solve problems as well as to consider sustainability through the activities. Based on the results, the study aims to provide implications for the direction of mathematics education for sustainable development in elementary school.

In this paper, we propose a prototype system for abnormal sound detection and identification which detects and recognizes the abnormal situations by means of analyzing audio information coming in real time from CCTV cameras under surveillance environment. The proposed system is composed of two layers: The first layer is an one-class support vector machine, i.e., support vector data description (SVDD) that performs rapid detection of abnormal situations and alerts to the manager. The second layer classifies the detected abnormal sound into predefined class such as 'gun', 'scream', 'siren', 'crash', 'bomb' via a sparse representation classifier (SRC) to cope with emergency situations. The proposed system is designed in a hierarchical manner via a mixture of SVDD and SRC, which has desired characteristics as follows: 1) By fast detecting abnormal sound using SVDD trained with only normal sound, it does not perform the unnecessary classification for normal sound. 2) It ensures a reliable system performance via a SRC that has been successfully applied in the field of face recognition. 3) With the intrinsic incremental learning capability of SRC, it can actively adapt itself to the change of a sound database. The experimental results with the qualitative analysis illustrate the efficiency of the proposed method.

In this study, chemical information on a total of 20 individual compounds was constructed to identify isoflavones from the previous reports related with used parts(seeds, leaves, stems, pods) and products of soybean(Glycine max L.). Through constructed library and UPLC-DAD-QToF/MS analysis, a total of 19 individual isoflavones including aglycones, glucosides, acetylglucosides and malonylglucosides as major compounds was identified and quantified from 14 selected soybean seeds. Among them, genistein 7-O-(2"-O-apiosyl)glucoside and genistein 7-O-(6"-O-apiosyl)glucoside(ambocin) were identified tentatively as novel compounds in soybean seeds. Besides, among malonylglucosides, glycitein 4'-O-(6"-O-malonyl)glucoside was estimated for the first time. Total isoflavone contents were distributed from 240.21 to 445.21(mg/100 g, dry matter) and 7-O-6"-O-malonylglucosides were composed of 77.8% on total isoflavone as well as genistein derivatives were confirmed as major class. It was considered importantly that the development of isoflavone-rich varieties was necessary to strengthen their effects such as anti-inflammation, anti-cancer and menopause mitigation. The qualitative and quantitative data presented precisely in this study could be help to select and breed isoflavone-rich varieties. Furthermore, their basic isoflavone profile is expected to be applied to estimate the change of isoflavone conjugates on bioavailability after soy food supplements.

This study conducted a systematic literature review on nursing students to find out the types and composition of patient safety-related education programs. The research was conducted systematically using PRISMA. The patient was a nursing college student, and the intervention was patient safety education. The outcome was either numerical or descriptive reports of the results measured using the tool. The types of research were carried out including randomized design, quasi-experimental design, one-group design, survey and qualitative research. The paper was searched through Medline, Embases, CINAHL, DBpia, Riss and KISS. A total of 2,468 papers were searched in the search results, and nine papers were used for analysis as a result of extracting data according to PICO. The characteristics of patient safety education of nursing college students were classified according to the teaching method, period, result variables and measurement tools. As a result, patient safety education consisted of a variety of subjects, and was being taught through lectures, clinical practice, laboratories, and simulations. The period of education also varied. The resulting variables were mainly checked for knowledge, attitude, and skill, and the tools used to measure them varied. Patient safety education for nursing college students was conducted through various topics, methods and periods at home and abroad. Therefore, continuous research is needed to establish consistent and integrated patient safety education in educational institutions and working institutions to produce nursing personnel with patient safety capabilities.

The purpose of this study is to understand the experiences of older adults living in the public welfare housing for the elderly and to examine what kind of this housing is as the housing alternative. Through the Robert Stake's intrinsic case study, it explored how older residents experienced this place, and how the relationships between residents, office workers, and community had been in the process, and what kind of issues were there. Various kinds of data, such as resident surveys, participant observations, interviews with 76 elderly residents and 4 office workers, and related newspaper articles, were analyzed using the thematic analysis method and methods suggested by Stake(1995). The results are presented as follows. First, it looked at who lived here and explored what was happening in this place where people of various backgrounds were gathered. Second, four types of life could be seen centering on the social relationship and daily life of older adults. Third, this study examined how the various ways of life were related to the main reasons for moving in here, and summarized how the residents perceived this place. The fourth and the fifth examined the relationships and dynamics among older residents, with office workers, and with the community, focusing on the two issues most commonly mentioned by residents. The results of this study show that, as a living organism, the interaction between the systems affects not only the culture of the housing, but also the lives of older adults. In particular, it can be seen how the perceptions of the practitioners are affecting the lives of the elderly. Based on the results of the study, further considerations were discussed.

The purpose of the study was to examine Korean high school students' experience and perceptions of friendship and to inductively conceptualize friendship. The concept mapping method which is used to quantitatively analyze qualitative data was used to identify and visualize participants' experiences and perceptions of friendship. Through a brainstorming process, 93 statements were generated by boys and 100 statements were generated by girls, each set of which were sorted and categorized to generate concept maps. The final concept maps from both group equally had two dimensions: 'Practical-Conceptual' and 'Behavioral-Emotional'. The number of categories was equal to four, but there were some differences in the specifics of the statements in the category. Boys tended to conceptualize friendship as a source of happiness; a type of informal relationship through which they could share their everyday lives; and provide mutual care and engage in emotional bonding. In addition to those conceptualizations, girls also tended to conceptualize friendship as an affective alliance through which they displayed devotion to each other. Boys regarded the sympathy and bonding found in and the happiness produced by friendship as more important elements, whereas girls regarded the care and support found in and the informal nature of friendship as more important

The aim of this study was to provide basic data for breeding new varieties of Angelica gigas Nakai by identifying the growth characteristics and useful components of its below- and above-ground parts. The basic varieties expressing dark purple (N79-A), light blue-pink (62-C), and white (NN115-C) flowers were identified and collected in the cultivation area, and their seeds were cultured for use as experimental materials. Qualitative growth characteristics of the above-ground parts were then examined. Purple coloration was evident throughout the entire plant body in the N79-A group, whereas the 62-C and NN115-C groups displayed yellow-green coloration. In terms of quantitative growth characteristics, the 62-C group displayed significantly lower above- and below-ground growth than the other two groups. Levels of nodakenin and decursinol-angelate were high in the NN115-C group (0.88 ± 0.13%) and N79-A group (2.56 ± 0.12%). However, the overall results were not statistically significant. The results could provide a foundation for breeding new varieties of Angelica gigas Nakai, which are used predominantly for medicinal purposes and have low bolting and high yield potential.

The purpose of this study is to understand the meaning of clinical practice experience, including web-based simulation practice, in the context of the corona pandemic era. As for the research method, data were collected through a focus group interview on the experience of web-based simulation practice and subsequent clinical practice and analyzed by content analysis method. The contents of the two interview groups were analyzed, and the results were divided into 2 components, 7 topic groups, and 18 topics. The first component, the clinical practice, was divided into four topic groups: 'The anxious start of practice in a pandemic situation', 'Direct experience through various cases', 'Training opportunities to prepare as a future nurse', and 'The burden of performance and limited experience'. The second component, the web-based simulation practice, was divided into three topic groups: 'Unfinished nursing practice', 'Indirect experience of clinical nursing in virtual space', and 'Requirement of an integrated practice model'. Clinical practice is a very important part of the nursing education curriculum. However, the nursing that students can perform in the field is very limited. Therefore, to supplement the shortcomings of observation-oriented clinical practice and to increase the quality of practical education, it is necessary to consider a hybrid education model including web-based simulation practice.
