      • Facile fabrication of platinum nanodots assembly core-silica shell nanosystems

        ( Diana ),유효종 한국공업화학회 2015 한국공업화학회 연구논문 초록집 Vol.2015 No.0

        Nanosystems using platinum (Pt) nanodots assembly (multi-Pt nanoparticles, m-Pt) as the core and silica (SiO2) shells were successfully synthesized as m-Pt@SiO2 spherical nanoparticles (NPs) and m-Pt@SiO2 nanochains (NChs) by a reverse microemulsion (water-in-oil) based method. The kinetically controlled reduction of K2PtCl4 by the Brij35 surfactant within reverse micelles, followed by condensation of tetraethyl orthosilicate (TEOS), led to the formation of multi-Pt nanodot core-slica shell systems. The reduction kinetics for the growth of coreshell systems were compared in both the presence of reducing agents and in the absence of supplementary agents, as well as the variation of water-to-surfactant ratio. To assemble Pt nanoparticles within in onedimensional silica matrix for m-Pt@SiO2 NChs, the pH of the reaction media was systematically changed.

        Needs Analysis of Students’ Pro-Environmental Behavior for Climate Change Books

        Diana Vivanti Sigit(Diana Vivanti Sigit ),Eka Putri Azrai(Eka Putri Azrai ),Ade Suryanda(Ade Suryanda ),Ilmi Zajuli Ichsan(Ilmi Zajuli Ichsan ),Michael B. Cahapay(Michael B. Cahapay ),Md. Mehadi Rahma 인간식물환경학회 2022 인간식물환경학회지 Vol.25 No.5

        Background and objective: Climate change is a current issue that need to be solved by innovation in environmental education. However, efforts specifically to develop a teaching material based on the learning needs of the students related to climate change has not been given attention. This study aims to describe the Pro-Environmental Behavior (PEB) of students as basis for the development of an educational material to be known as Climate Change Book Series (CCBS-US). Methods: It entailed a descriptive research design and survey method, involving a sample of 642 students in Jakarta and Semarang, Indonesia. The data were treated using descriptive statistics. Data analysis using ANOVA test to see the significant of the difference between each group. Results: The results indicate that the university students’ PEB score is high while the high school students’ PEB score is moderate. The lowest average score is found in aspects related to efforts in reducing garbage and recycling. Details of average score were Junior high school students (74.49), senior high school students (66.28), Faculty of Math and Science university students (73.69), Non-Faculty Math and Science university students (72.27). Conclusion: It is along these inputs that the CCBS-US must be developed as a learning material in environmental education. It is hoped that the results of this study, the developed CCBS-US can significantly empower students' PEB scores in classroom learning.

        The Food Delivery App Information Design Suggestion for Foreigners in South Korea

        Diana Iziiatullina,Jinyeon Shin,Aygul Akhmetova,박수진 한국멀티미디어학회 2022 The journal of multimedia information system Vol.9 No.4

        Many foreigners living in South Korea faces various problems in their daily lives, such as language barriers, cultural differences, etc. This also applies to making food orders via mobile applications. A lot of foreigners have difficulties using food delivery apps for various reasons. The purpose of this study is to create a functional design of food delivery app for foreigners based on a survey. As a part of this study, we conducted a survey among foreign residents in South Korea to identify and analyze user needs. After analyzing the survey results, we proposed a mobile app design based on user experience. As a result, we created a new design interface that includes a full English translation of the entire menu and information about food allergens. Besides, information about nutrients, ingredient’ origin, the pungency indicator and the label of vegan and halal food also have been added to the application interface.

        Women’s Resistance to Globalization

        Diana J. Mendoza(다아에나 멘도사),Dong-Yeob Kim(김동엽) 한국정치학회 2005 한국정치학회보 Vol.39 No.4

        본 논문은 신자유주의적 세계화의 물결에 저항하는 여성운동의 본질과 형태, 쟁점과 전략 그리고 이러한 저항에 대한 국가의 반응에 대한 연구이다. 세계화는 성(性)에 대한 관념을 포함한 사회적 관계에 많은 영향을 미치고 있다. 신자유주의적 세계화는 공적영역이 시장의 역할로 대체되는 현상 뿐만 아니라 그 영향이 가족에게까지 확대되어 전반적인 사회적 관계를 재구축하고 있다. 이러한 세계화의 영향은 가족성원이나 공동체 활동에 대한 여성들의 부담을 점점 증가시키는 측면으로 뚜렷이 진행된다. 필리핀과 한국에 대한 사례를 통해 서로 다른 경제적 상황과 세계화에 대한 상이한 정책 하에서 다양한 부류의 여성들이 직면하는 위기뿐만 아니라 이에 대항하는 여성 운동가들의 성(性)인지적 정치세력화 현상을 소개한다. 두 국가의 사례에 대한 연구를 통해 세계화는 각 국가의 경제발전 수준에 따라 그 영향의 형태가 다르게 나타나며, 이에 대항하는 여성운동의 형태와 국가의 반응에서는 유사점이 부각된다. 이는 세계화가 저항의 다양한 이유와 쟁점들을 여성에게 제공하지만, 저항의 형태에 있어서는 개별 국가들이 직면하고 있는 상황에 관계없이 보편성을 가짐을 보여준다. 세계화는 이전의 사회적 관계를 지속시킬 뿐만 아니라 전통적인 성(性)관계도 계속 유지한다. 이러한 세계화의 흐름에 대한 도전은 여성들의 힘을 증진시키는 계기를 만들고, 또한 다양한 형태의 여성에 대한 착취와 소외는 새로운 형태의 집단저항으로 이끈다. This study is an inquiry into the nature, forms, sites, and strategies of resistance to globalization by women’s organizations, and the state’s policy response to such resistance. The processes of globalization have affected social relations including the gender contract. There has been a re-articulation of the public-private divide, not just in terms of a shift from the public sector to the market, but also to the household. This is most clearly manifested in increased burden on women in terms of caring for family members or additional community-related activities due to globalization. The cases of the Philippines and South Korea highlight not only the vulnerabilities of various groups of women to different economic restructuring and trade liberalization regimes, but also the gendered nature of political organizing among women activists. Between the two country cases, differences revealed in the forms that globalization affects each country depending on the level of economic development, and similarities were more prominent in the pattern of women’s movement and the state response. It demonstrates that globalization causes different reasons for and sites of women’s resistance, but it opens a general pattern of solving problems regardless of the situation each country confronts. Globalization does not only perpetuate previous social relations but also maintains traditional gender relations. Challenging these creates opportunities for women’s empowerment and generates new forms of collective resistance to various expressions of exploitation and marginalization of women.

      • Development and preliminary psychometric analysis of a quick screening form for referrals of individuals with neurogenic communication disorders to speechlanguage pathologists by laypersons

        Diana Wai-Lam Ho,Anthony Pak-Hin Kong,Olivia Ho-Yi Yeung,Samson Wai Yeung 한국언어재활사협회 2020 Clinical Archives of Communication Disorders Vol.5 No.1

        Purpose: The study aimed at developing and determining the preliminary reliability and validity of a new screening form for use by laypersons to refer individuals with neurogenic communication disorders to speech-language pathologists. Methods: Thirty-two native Cantonese speakers with neurogenic communication disorders were tested with the proposed screening form by fourteen volunteer raters and well-established speech and language tests for aphasia, dysarthria and apraxia of speech (AOS) by ten speech-language pathology students. Results: Statistical analyses showed that the internal consistency and inter-rater reliability were high in all the tasks for aphasia and most of the tasks for dysarthria and AOS of the proposed screening form. It was further identified that some of the tasks for aphasia, dysarthria, and AOS would be valid for laypersons to identify individuals with communications disorders. Conclusions: The results indicated that the tasks for screening aphasia, dysarthria, and AOS should be carefully selected so that untrained laypersons would be able to make correct judgements. Further investigations involving a larger sample size are needed to determine areas to enhance the sensitivity and discriminating power of the current screener to be used by laypersons without a clinical background.
