In this paper, we researched the excellency of 3D graphic nursery contents which is developed by mobile AR technology. AR technology has currently people's attention because of the potential to be core contents of future ICT industry. We applied AR nursery contents for kid's subtitle language selection in Korean, Chinese and English education. The original fairy tale consisted of 6~8 scenes for the 3D contents production, and was adapted and translated. Dubbing was dubbed by the native speaker using the standard pronunciation, and the effect sound was edited separately to fit the scene. After composing a scenario, constructing a 3D model, constructing a interaction, constructing a sound effect, and creating content metadata, the Unity 3D game engine is executed to create a project and describe it as a script. It provides a fun and informative tradition of fairy tales with abundant content that incorporates ICT technology, accepting advanced technology-based education, and having opportunities to perceive software in daily life.

The study is based on the assumption that the trend of phenomena and trends in research are contextually consistent. Therefore the purpose of this study is to explore the trend of dance through the subject analysis of the Korean creative dance study by utilizing text mining. Thus, 1,291 words were analyzed in the 616 journal title, which were established on the paper search website. The collection, refining and analysis of the data were all R 3.6.0 SW. According to the study, keywords representing the times were frequently used before the 2000s, but Korean creative dance research types were also found in terms of education and physical training. Second, the frequency of keywords related to the dance troupe's performance was high after the 2000s, but it was confirmed that Choi Seung-hee was still in an important position in the study of Korean creative dance. Third, an analysis of the overall research subjects of the Korean creative dance study showed that the research on 'Art of Choi Seung-hee in the modern era' was the highest proportion. Fourth, the Hot Topics, which are rising as of 2000, appeared as 'the performance activities of the National Dance Company' and 'the choreography expression and utilization of traditional dance'. However, since the recent trend of the National Dance Company's performance is advocating 'modernization based on tradition', it has been confirmed that the trend of Korean creative dance since the 2000s has been focused on the use of traditional dance motifs. Fifth, the Cold Topic, which has been falling as of 2000, has been shown to be a study of 'dancing expressions by age'. It was judged that interest in research also decreased due to the tendency to mix various dance styles after the establishment of the genre of Korean creative dance.

This study was performed to investigate the reaction between alkylketene dimer(AKD) and cellulose molecules in AKD-sized paper sheet. AKD was added to highly beaten($80{\pm}3^{\circ}SR$) SwBKP(ca. 0.8% on pulp) in order to have much AKD retention in the paper sheet. This AKD-sized paper sheet was aged at different temperatures, $60^{\circ}C,\;80^{\circ}C,\;105^{\circ}C\;and\;125^{\circ}C$. Changes in FT-IR spectra of AKD in paper sheet during the ageing were measured. In addition, sizing degrees of the AKD-sized paper sheet pretreated for 30 sec. at $105^{\circ}C$ were measured by HST size tester during the storage at different temperature. IR spectra of AKD-sized paper sheet preheated at $105^{\circ}C$ for 30 sec. showed unchanged spectra two absorption bands at $1849cm^{-1}\;and\;1722cm^{-1}$ which refer to the typical AKD IR bands. However, these typical AKD bands were gradually reduced with increasing ageing, completely disappeared after 6 hrs. and formed new absorption band at $1706cm^{-1}$, which refers to carbonyl stretching vibration of dialkylktone. Eventually the AKD molecule was hydrolyzed to diakylketone without formation of ${\beta}$-ketoester with cellulose in paper sheet. After 6 days ageing, a little amount of ${\beta}$-ketoester bands was identified in 6 or 7 days ageing, because of the absence of water due to long-term heating. The same tendency was observed at different ageing conditions. At the practical papermaking process, AKD reacts prevailing with water, and mostly seems to be hydrolyzed to dialkylketene. Concerned to the sizing development, AKD-sized paper sheet was shown no sizing development at the initial stage of ageing at $60^{\circ}C$ after heating treatment at $105^{\circ}C$ for 30 sec., and gradually increased the sizing degree with increasing ageing, such as Hercules Sizing Tester (HST) 130 see for 12 hr, HST 300 sec. for 3 days and HST 400 sec. for 5 days. It was concluded that hydrolyzed AKD could contributed to the sizing development of the paper sheet.

Digital inclusion is the ability or opportunities of individuals and groups to access and use information technology (IT). Digital inclusion strategies aims to ensure that all citizens regardless of their gender, race and class benefit from IT. Discourse of digital inclusion is notable in that it proposes a desirable relationship between the state, individuals, and the market within the shifting topology of technoscience. Throughout broad discourse analysis of media coverages, in-depth interviews and reports on Korean IT industry, this research argues that dialogues on digital inclusion have substantially influenced the formation of a specific ethical regime. In this regime, individuals should become subjects embodying IT expertise and acceptable codes of conducts. We further discuss that such government-driven ethical regime conflicts with technological citizenship practiced by IT experts and semi-experts. We make theoretical contribution to STS by expanding the concept of technological citizenship to include the rights and obligations of heterogeneous expert and semi-expert groups to form, propose and socially demand alternative developmental pathways of technoscience. We also note that, amid the conflict between ethical regime and technological citizenship, alternative interpretations of gender gap can be forged, providing competing perspectives on women's under-representation and labor conditions in the IT industry. Further research is required to capture the emergence of multiple identities--differentiated by gender, race, class, and more--within the clashing interface between the ethical regime and technological citizenship.

효율적인 wet-end시스템의 적용으로 중성 초지시스템의 이점을 최대한 구현하고 이에 따른 초지계의 안정성 및 원가절감 등을 얻기 위해서는 중성 초지 시스템에서 사용되는 사 이즈제 및 사이징 공정에 대한 연구가 매우 중요하다. 현재 중성 사이즈제로는 AKD와 A ASA가 가장 널리 사용되고 있는데, 유럽에서는 주로 AKD가 쓰이고 있으며, 미국에서는 A ASA가 50%정도 사용되고 있다 .. AKD에 비해서 ASA는 사이즈도의 발현이 매우 빨라 사이 즈 프레스에서 사이즈도가 발현되므로 사이즈 프레스에서의 픽엽 조절 및 지절감소에 유리 한 장점을 가지고 있다. 하지만 ASA는 AKD에 비해 반웅성 높아 습부에서의 가수분해되어 초지 조업성을 악화시키는 문제점을 지니고 있다. 이러한 문제를 극복하기 위해서는 ASA 유화액의 정착성을 개선시키기 위한 연구가 시급히 요청되고 있으며 여기에는 ASA의 유화 에 사용되는 양성전분의 최적화가 가장 핵심적인 기술로 평가된다. 현재 ASA용 유화제로는 양성전분이 가장 많이 사용되고 있다. ASA 에멀션 제조에 있 어서 양성전분의 역할은 음전하를 가지고 있는 ASA 입자에 홉착되여 양전하를 부여함으로 써 콜로이드 업자의 안정성을 부여할 뿐만 아니라 섬유와의 정전기적 인력을 유도하여 정착 을 증진시키는 효과를 나타낸다. ASA 유화용으로 쓰이는 양성전분 중에서는 감자전분이 가 장 효과적인 것으로 알려져 있으며 옥수수나 타피오카 둥도 쓰이고 있다. 그러나 국내의 경 우 감자전분은 옥수수전분보다 가격이 비싸다는 단점이 있으므로 저렴한 옥수수 전분을 이 용하여 ASA 유화용 변성전분의 개발이 국내 제지산업의 경쟁력 강화를 위해 시급히 요망 되고 있다. 본 연구의 목표는 옥수수 전분을 이용한 ASA용 유화안정제를 개발하고 그 효과를 극대 화시킬 수 있는 적용기술을 확립하는데 있다. 옥수수전분을 이용한 ASA 유화용 변성전분은 외국에서 소개된 바가 있기는 하지만 사이즈도 발현이 감자전분의 절반 수준으로 효과적이 지 못한 것이 문제점으로 지적된 바 있다. A ASA 유화용 전분으로는 감자전분과 옥수수전분으로 제조된 외국산 기존 제품과 본 연 구를 통해 개발된 옥수수 전분을 이용하였다. 먼저 실험실적으로 최적의 ASA 에멸션의 유 화가 가능하도록 유화조건을 설정하여 유화액의 입도가 1µm 정도가 되도록 하였다. 이들 A ASA 사이즈제를 Hw. Sw-BKP로 조성된 지료에 투입하여 수초한 후 Hercules 사이즈도 측정기를 이용하여 수초지의 사이즈도를 측정하였다. 또 사이정 효과를 극대화시키기 위한 방안을 모색하기 위해 ASA 에말션의 입도, 제타전위, 탁도 등의 평가를 병행 실시하였다. 실험 결과 기존의 방법으로 유화한 경우 수입감자양성전분이 가장 높은 사이즈도를 보였 다. 그러나, 적절한 전분변성법과 유화조건을 개선함으로써 옥수수전분을 이용하여 수입 감 자전분이나 수입 옥수수전분보다 더 우수한 ASA 사이정 효과를 나타내는 양성전분이 개발 될 수 있음을 확인하였다.

The purpose of this study is to suggest the direction of the funeral culture industry suitable for the age of longevity and well-aging through a study on changes in the perception of funeral culture among the elderly. The survey of this paper was conducted by Gallup Korea, and the survey method was a 1:1 individual interview using a structured questionnaire. The survey was conducted from October 1 to October 25, 2021, targeting 127 elderly people over the age of 65 living in Seoul, Incheon, and Gyeonggi-do. The number of valid subjects was 110, and the sampling method used was allocation by sex/age/income level/religion. As a result of the study, as for the change in the perception of funeral culture among the elderly, women preferred cremation to men (p=0.034). It was investigated that the level of income (p=0.004) and religious status (p=0.020) had an effect on funerals while alive. According to the presence or absence of thoughts about death, there was a significant difference in the membership of the mutual aid product (p=0.008) and the intention to return to a religious organization (p=0.004) when a memorial service was held. The results of this study are expected to be usefully utilized in presenting the direction and policy of the funeral culture industry suitable for the age of well-aging in the future.
