Ion-beam irradiation(IB) on HfO2 surface induced high-performance liquidcrystal(LC) driving at a 1-V threshold with vertical alignment of liquid crystals(LC). The high-k materials Atomic layer deposition was used to obtain LC orientation on ultra thin and high-quality films of HfO2 layers. To analyze surface morphological transition of HfO2 which can act as physic alignment effect of LC, atomic force micro scopy images are employed with various IB intensities. The contact angle was measured to elucidate the mechanism of vertical alignment of LC on HfO2 with IB irradiation. Contact angle measurements show the surface energy changes via IB intensity increasing.

This study investigated the trend of research on ‘Food science and Nutrition’ in previously published papers in the Journal of Korean Society of Food Culture (JKSFC) from 2000 to 2021. Total number of published papers in this category in the JKSFC was 693 which we classified into 7 main categories and 40 subcategories. Of these, 256 articles were on ‘experimental cooking’ which was the most studied field among 7 main categories. There was a total of 19 published papers under the category of ‘microbiology and fermentation’. A total of 133 articles were published on ‘functional foods’ and provided essential data for discovering new materials under the theme of various physiological active functions of food materials. Furthermore, 107 articles were included in ‘food processing and storage’, which provided integrated knowledge of economy, stability and practicality based on various technologies. A total of 144 articles was included in the category of ‘nutrition’. Under the category of ‘nutrition’, the most actively studied topic was ‘eating behaviors and dietary habits,’ and the trending topic was ‘use of healthcare big data.’ In conclusion, this review would provide trends of various categories of food science and nutrition area for recent 21 years and suggest directions for future research.

본 연구는 문학과 종교를 아우르는 연구 방법론을 탐색함을 목적으로 한다. 첫째, 문학의 연구 방법과 종교학의 연구 방법의 유사점과 차이점에 대해서 설명하고 각각의 연구 방법에는 어떤 것들이 있는지 유형화했다. 역사학, 사회학, 심리학 혹은 정신분석, 철학, 현대 비평 이론과 같은 학문적 유형과 과학과의 관계, 비교, 해석과 같은 활동으로서의 유형이 있음을 발견하게 되었다. 둘째, 이를 바탕으로 그동안 한국문학과종교학회를 통해 발표된 논문들에서 어떤 연구 방법들이 사용되었는지 살펴보았다. 여기서 발견한 주목할 만한 방법론적 경향성은 문학 작품 속에 나타난 종교적 주제를 다양한 개념적 도구를 사용하여 해석하는 것이다. 또한 종교 현상이나 종교 텍스트 자체를 분석하는 연구도 두드러진 흐름이다. 외국 작가나 작품과 한국 작가나 작품을 비교하는 연구 역시 찾아볼 수 있다. 이 논문의 마지막 부분에서 한국문학과종교학회의 스펙트럼이 더 넓어질 수 있도록, 그리고 새로운 도약을 이룰 수 있도록 몇 가지 제안을 덧붙인다.

This study examines the trend of research on food and culture in papers published in the Journal of The Korean Society of Food Culture from 1986 to 2020. The journals published a total of 329 papers, which we classified into 5 main categories and 13 middle categories. Of these, 204 articles were on “Korean traditional food culture.” The most studied topic in the entire period was “Perception of Koreans towards traditional food, preference, satisfaction, and usage.” A total of 76 studies related to “Korean contemporary food culture.” The most advanced topic researched concerned “Recognition and attitude”; these studies were consistently carried out throughout the research period. The main classification of “World food culture” encompassed 32 studies, with major research focused on “World's Modern Food Culture” and the most advanced being “Comparison of Food Cultures of Foreign and Korean Food Cultures.” All studies were consistently spaced out during the study period. These studies provide an integrated knowledge in the field of food and culture and can be used as a basic material for related research in the future.

For any research study, in order to achieve the researcher’s intended purpose, the depth of research is added, and the area of the subject is expanded by clearly defining the scope and objective. The study was undertaken to analyze the bibliographic data of 254 papers in the field of foodservice and restaurant published in the Journal of the Korean Society of Food Culture from 2002 to 2021. The study was divided into two periods: 2002 to 2011, and 2012 to 2021. Research topics were derived and research trends according to temporal changes were confirmed through analysis of keyword networks by period. In addition, analyzing the keyword network of simultaneous appearance of “foodservice” and “restaurant”, the research topics were compared and analyzed in relation to which keywords were expanded by period. Our analysis revealed that the research topics were mostly studied for satisfaction and nutrition. Additionally, they were classified into procurement, Korean food before employee menu, marketing, restaurant industry, and quality. In the period from 2002 to 2011, it was confirmed that studies encompassed a wide range of research topics, focusing on foodservice and restaurant; in the second period from 2012 to 2021, the research topics were more classified and subdivided.

Purpose: This study aimed to identify research trends by applying the scoping studies method to articles published from the establishment of the Korean Society for Nursing Simulation in 2011 to June 2021, and to suggest the direction for future research. Method: A total of 73 articles were reviewed by applying the six steps and recommendations for scoping studies as suggested by Arksey and O'Malley. Results: Focusing on the subjects, research topics were classified comprehensively into the experience of nursing students, nurses, professors, and office workers. As a result of analyzing the research process characteristics, practical teaching and learning using simulation technology resources were conducted during most of the research, and a systematic curriculum for learning promotion was devised and applied. Furthermore, nursing performance ability was evaluated, learning situation was identified, and simulation education situation and necessity of clinical field were identified. The keywords “applied technology,” “teaching-learning method,” “environment,” “cognition,” “attitude,” “affect,” “patient status,” “nursing,” and “nursing performance” were identified as eight categories. Conclusion: The post-coronavirus era has provided an opportunity to expand the scope of Korean nursing simulation research, which is going to further contribute to nursing development.
