도지윤,구본욱,유병조,배종욱,박제성 한국공업화학회 2018 한국공업화학회 연구논문 초록집 Vol.2018 No.0

Retinol is used as a raw material for anti-aging cosmetics because of its superior effects on anti-wrinkle and skin aging. However it is known that retinol is easily decomposed by light and heat and could induce skin irritation. So the stability is the most important property for a functional cosmetic material such as anti-aging products. In addition, the retinol used in the domestic cosmetics industry is entirely supplied from abroad. Thus it is required to develop a cheap and improved synthesis process for retinol derivatives to solve these problems. In this study, retinol derivatives were synthesized from the commercial retinol and characterized by several analyses such as NMR, FT-IR and SEM.

This study attempted to grasp the status and perception of Uljin Geumgangsong by grasping mass media issues and user perception using big data, and to present basic data when constructing monitoring using user perception by examining the establishment relationship of agenda setting from a time-series perspective. The results of collecting and analyzing text data that can identify mass media and visitor awareness are as follows. First, both mass media and visitor keywords were related to the importance of the value and meaning of Uljin Geumgangsong. Second, in the case of the connection network, Geumgang Pine Agriculture was centered, but in the case of difference in perception between mass media and visitors, such results were derived due to the object of interest. Third, in the case of the connection relationship structure, the connection strength was strong because there were many overlapping contents of mass media. Fourth, as a result of the centrality analysis, both mass media and visitor-aware keywords were positively recognized as spaces created and maintained through institutional support, and objective perception could be grasped by finding hidden keywords. Fifth, as a result of time series analysis, it was possible to grasp the flow through the issue keywords that appeared by period, and unlike the past, it was recognized as a place for tourism and travel. Finally, as a result of examining whether the agenda setting is consistent, there is a mass media influence, so it is thought that more diverse and more information and publicity are needed by utilizing it.

This study identified visitors' perceptions of KIAHS, which is being implemented to preserve tangible and intangible agricultural resources that have long been formed while adapting to the local environment, society, and customs. The purpose of the study is to derive the characteristics of use of resources and behaviors in agricultural heritage areas and to present sustainable development directions. Therefore, the contents of the characteristics based on the collection and analysis of blog and cafe data from the start of the KIAHS system to the present are as follows. First, through the analysis of the upper keywords, it was found that visitors were aware that the agricultural heritage area was a space with intangible characteristics, and that the purpose of the trip was caused by historical and cultural values. Second, as a result of the keyword network analysis, it was found that the representative resources of the region were important factors influencing visitor perception as the agricultural heritage area and representative resources were connected. Third, from a time-series perspective, a number of keywords matched the purpose of implementing the agricultural heritage system were derived, but it was confirmed that measures to expand KIAHS awareness were required as they appeared intensively after GIAHS registration. In addition, it was found that it was necessary to promote the understanding and awareness of the system through emotional analysis. KIAHS’s a place with historicity and representation, and needs to be approached from various perspectives such as knowledge, culture, and scenery, and if additional detailed regional characteristics are reviewed, regional revitalization measures can be prepared based on regional representative resources. 본 연구는 지역의 환경·사회·풍습 등에 적응하면서 오랫동안 형성시켜온 유형·무형의 농업자원을 보전하기 위해 시행되고 있는 국가중요농업유산(KIAHS)에 대한 방문객의 인식을 파악함으로써 농업유산지역의 자원과 행태 등의 이용 특성을 도출하고 지속가능한 발전 방향을 제시하는 것에 연구의 목적이 있다. 이에 KIAHS제도 도입 시점부터 현재까지의 블로그 및 카페 데이터 수집과 분석을 토대로 특성을 고찰한 내용은 다음과 같다. 첫째, 상위 키워드 분석을 통해 농업유산지역이 무형의 특성을 보유한 공간이라는 것을 방문객이 인지하고 있는 것으로 나타났으며, 여행의 목적이 역사문화적 가치로 인해 발생되고 있음을 알 수 있었다. 둘째, 키워드 연결망 분석 결과 농업유산지역과 대표자원이 연결되고 있어, 지역의 대표자원이 방문객 인식에 영향을 미치는 중요한 요소임을 알 수 있었다. 셋째, 시계열적 관점에서 살펴본 결과 농업유산제도 시행목적에 정합한 키워드가 다수 도출되었으나, 세계중요농업유산(GIAHS) 등재 이 후에 집중적으로 등장하여 KIAHS 인식 확대 방안이 요구됨을 확인할 수 있었다. 또한, 감성분석을 통해 제도에 대한 이해와 인식 확대 등을 위한 홍보가 필요한 것을 알 수 있었다. KIAHS는 역사성과 대표성을 보유한 곳으로 지식, 문화, 경관 등 다양한 관점에서 접근할 필요가 있으며, 추가적으로 세부적인 지역별 특성에 대한 고찰을 진행한다면 지역의 대표자원 인식을 근거로 지역 활력화 방안을 마련할 수 있을 것으로 판단된다.

도지윤,정명철 한국환경영향평가학회 2023 환경영향평가 Vol.32 No.4

This study was aimed to derive the following regional characteristics and implications by reviewing the effects of local communities and overseas cases through agricultural heritage and related systems to prepare rural regeneration measures using agricultural and rural heritage. First, The study was examined to improve the awareness to improve awareness of the value and preservation of heritage through the designation of agricultural heritage. However, it was found that it was necessary to prepare for social problems such as the aging population in the future. Second, most of the residents’ perceptions showed a positive perception of the designation of agricultural heritage, but they were somewhat less recognized in terms of economics, so it was found that regeneration measures were needed to compensate for this. Third, as a result of applying the effect measurement model, the preservation and management effect that meets the purpose of the system is high, and the effect varies depending on projects such as local governments and residents’ councils. Fourth, as a result of examining rural regeneration measures through overseas cases, it was found that rather than large-scale development, various cultural and natural resources and activation measures were prepared by expanding the scope to surrounding areas. This study was conducted only on agricultural heritage areas, but it is meaningful that agricultural and rural heritage should be reviewed from various perspectives suitable for the current trend, and it is meaningful in that it considers not only local residents’ perception but also regional effects and revitalization measures. 본 연구는 농업·농촌유산을 활용한 농촌 재생 방안을 마련하기 위하여 농업유산과 관련 제도를 통해 발생하는 지역사회 효과 검토와 해외 사례를 고찰함으로써 다음과 같은 지역 특성과 시사점을 도출할수 있었다. 첫째, 농업유산 지정을 통해 유산의 가치 및 보전에 관한 인식 향상을 도모할 수 있었다. 그러나 추후 발생할 인구 고령화 등 사회문제에 대비할 수 있는 지역의 보전·관리 방안 마련이 필요한 것을 알수 있었다. 둘째, 주민 인식은 농업유산 지정에 대하여 대부분 긍정적 인식을 보였으나, 경제적인 부분에서는 인식이 다소 떨어지므로 이를 보완할 수 있는 재생 방안이 필요함을 파악할 수 있었다. 셋째, 효과측정 모델을 적용한 결과 제도의 목적에 부합하는 보전·관리 효과가 높게 나타나고 있으며, 지자체와 주민협의체 등의 사업에 따라 효과에 차이가 있으므로 재생 방안 마련 시 목표 지향적인 대안이 필요한 것을 알수 있었다. 넷째, 해외 사례를 통한 농촌 재생 방안을 살펴본 결과 대규모의 개발보다는 다양한 문화·자연자원과 주변 지역까지 범위를 확대하여 활성화 방안을 마련하고 있음을 알 수 있었다. 본 연구는 농업유산지역만을 대상으로 연구를 수행하였으나, 현재 흐름에 걸맞은 다양한 관점으로 농업·농촌유산을 검토해야할 것으로 판단되며, 지역주민 인식뿐만 아니라 전문가 설문 등 지역의 지정 효과와 활성화 방안을 함께 고찰한 점에서 의의가 있다.

도지윤,정명철 한국환경영향평가학회 2022 환경영향평가 Vol.31 No.3

The purpose of this study is to explore the purpose of introducing the system and the possibility of development by comparing the period before and after the implementation of the Korean Important Agricultural Heritage System (KIAHS) using big data. In terms of perception related to Ulleungdo Island, keywords related to accessibility were derived as higher keywords before and after designation, and in particular, keywords such as various approaches and new ports could be found after designation. It can be seen that positive perception increased after the designation of KIAHS, and the perception of good increased particularly. In addition, the exact name of wild greens and keywords for volcanic island appeared in common, but it was confirmed that the influence increased in the results of the centrality analysis after the designation. In other words, it was found that the designation of KIAHS was helpful in preserving traditional knowledge and developing traditional agricultural culture using it. 본 연구는 빅데이터를 활용하여 국가중요농업유산(KIAHS; Korean Important Agricultural Heritage System) 제도 시행 전후 기간을 비교하여 방문객 인식 특성을 파악함으로써 제도 도입의 효과와 발전 가능성을 모색하는데 목적이 있다. 울릉도와 관련된 인식은 지정 전후 모두 접근성과 관련된 키워드가 상위 키워드로 도출되었으며, 특히 지정 이후 다양한 접근 방법과 새로운 개항 등의 키워드를 찾아볼수 있었다. 국가중요농업유산 지정 이후 긍정적인 인식이 증가하였으며, 호감의 인식이 증가한 것을 알 수있다. 또한, 공통적으로 정확한 작물의 이름과 화산섬에 대한 키워드가 나타났으나, 지정 이후의 중심성 분석 결과에서 영향력이 높아진 것을 확인할 수 있었다. 즉, 전통지식 보전과 이를 활용한 전통 농업문화의발전에 도움이 되고 있음을 알 수 있었다.

도지윤,서기춘,정명철,최진아 한국환경영향평가학회 2023 환경영향평가 Vol.32 No.4

This study was conducted for the purpose of the basic direction for the new regulations and categories of Ruralism changing in the new era. To this end, the results of Delphi analysis and AHP analysis by dividing it into the definition, criteria, scope and component items of Ruralism based on systematic literature review are as follows. First, through studies representing most rural areas, it was found that Ruralism was the most problematic keyword and most of the studies did not cover it as they were studying various ranges of rural areas. Second, the Delphi survey was able to derive keywords that can be used as evidence for item classification and clear concept establishment for the regulation and category setting of Ruralism. Third, through the hierarchical decision-making method, it was found that landscape factors are the most important thing in forming Ruralism as well as deriving priorities that can be a baseline for each item. This study is meaningful in providing a minimum baseline as basic data for establishing the concept of Ruralism, and it is believed that future-oriented Ruralism can be established if reviews are added from various perspectives to overcome limitations dependent on expert groups. 본 연구는 새로운 시대에 변화하는 농촌다움의 새로운 규정과 범주를 위한 기초적 방향을 목적으로수행되었다. 체계적 문헌고찰을 토대로 농촌다움의 정의, 기준, 범위, 구성요소 항목으로 구분하여 델파이분석과 AHP분석을 실시한 결과는 다음과 같다. 첫째, 대부분의 농촌을 표상하는 연구를 통해 농촌다움이가장 이슈가 된 키워드임을 파악할 수 있었으며, 농촌의 다양한 범위를 각각 연구하고 있어 이를 포괄하지못하는 연구가 대다수임을 알 수 있었다. 둘째, 델파이 조사를 통하여 농촌다움의 규정 및 범주 설정을 위한 항목분류와 명확한 개념 정립을 위한 근거자료로 활용될 수 있는 키워드를 도출할 수 있었다. 셋째, 계층적 의사결정법을 통하여 항목별 기준선이 될 수 있는 우선순위 도출뿐만 아니라 경관적인 요인이 농촌다움을 형성하는 가장 중요한 것임을 파악할 수 있었다. 본 연구는 농촌다움 개념 정립을 위한 기초자료로 최소한의 기준선을 제공한 것에 의의가 있으며, 전문가 집단에 의존한 한계점을 극복하기 위하여 다양한 관점에서의 검토가 추가된다면 미래지향적인 농촌다움을 설정할 수 있을 것으로 판단된다.

도지윤,김수연 한국환경영향평가학회 2023 환경영향평가 Vol.32 No.6

This study attempted to find a way to utilize idle spaces in rural areas as a way to respond to rural extinction. Based on the keywords “startup,” “youth start-up,” and “youth start-up+rural,” the study sought to identify the perception of idle facilities in rural areas through the keywords “Idle facilities” and “closed schools.” The study presented basic data for policy direction and plan search by reviewing frequency analysis, major keyword analysis, network analysis, emotional analysis, and domestic and foreign cases. As a result of the analysis, first, it was found that idle facilities and school closures are acting importantly as factors forregionalregeneration. Second, in the case of youth startups in rural areas, it was found that not only education on agriculture but also problems forresidence should be solved together. Third, in the case of young people, it was confirmed that it was necessary to establish digital utilization for agriculture by actively starting a business using digital. Finally, in order to attract young people and revitalize the region through best practices at home and abroad, policy measures that can serve as various platforms such as culture and education as well as startups should be presented in connection with local residents. These results are significant in that they presented implications for youth start-ups in rural areas by reviewing start-up recognition for the influx of young people as one of the alternatives forthe use of idle facilities and regionalregeneration, and if additional solutions are presented through field surveys, they can be used to set policy goals that fit the reality. 본 연구에서는 농촌소멸 대응을 위해 농촌 유휴공간을 활용할 수 있는 방안 모색을 목적으로 하였다. 연구는 ‘유휴시설’, ‘폐교’ 주제어를 통해 농촌지역 유휴시설에 관한 인식을 파악함과 동시에 ‘창업’, ‘청년창업’, ‘청년창업+농촌’ 키워드를 토대로 유휴시설의 청년인구 유입을 위한 활성화 방안을 마련하고자 하였다. 연구는 빈도분석 및 주요 키워드 분석, 연결망분석, 감성분석과 국내·외 사례를 검토함으로써 정책 방향 및방안 모색을 위한 기초자료 제시를 실시하였다. 분석된 결과 첫째, 유휴시설 및 폐교는 지역재생을 위한 요소로서 중요하게 작용하고 있음을 알 수 있었다. 둘째, 농촌지역 청년창업의 경우 농업에 대한 교육뿐만 아니라 거주를 위한 문제가 함께 해결되어야 함을 알 수 있었다. 셋째, 청년계층의 경우 디지털을 활용한 창업에 적극적임으로 농업을 대상으로한 디지털 활용 구축이 필요한 것을 확인할 수 있었다. 마지막으로 국내·외 우수사례를 통해 청년 유입 및 지역활성화를 위해서는 지역주민과 연계되어 창업뿐만 아니라 문화와교육 등 다양한 플랫폼 역할을 할 수 있는 정책적 방안이 제시되어야 할 것으로 나타났다. 이와 같은 결과는 유휴시설 활용 및 지역재생을 위한 대안 중 하나로 청년인구 유입을 위한 창업인식을 검토함으로써 농촌지역의 청년창업에 관한 시사점을 제시했다는 점에서 의의가 있으며, 현장조사를 통하여 추가적인 해결방안을 제시한다면 현실에 맞는 정책 목표 설정에 활용될 수 있을 것으로 판단된다.

A Generalized Lichen Planus Following COVID-19 Vaccination: A Case Report

도지윤,이지현 대한피부과학회 2023 Annals of Dermatology Vol.35 No.-

As part of the efforts to overcome the ongoing coronavirus disease 2019 (COVID-19) pan- demic, mass vaccination programs against the severe acute respiratory syndrome coronavi- rus 2 (SARS-CoV-2) have been initiated. Since then, an increasing number of cutaneous ad- verse events associated with the COVID-19 vaccines have been reported. Lichen planus (LP) is a rare inf lammatory mucocutaneous disease with various clinical presentations, although uncommon, occurring following vaccination. There have been several cases of LP reported following COVID-19 vaccination. However, there has been no report of generalized LP fol- lowing the COVID-19 vaccine to our knowledge. Herein, we report a case of generalized LP following the Oxford/AstraZeneca (AZD1222) vaccine. A 68-year-old female presented with widespread, erythematous pruritic papules and plaques on the trunk and both limbs, which developed 2 to 3 days after administration of the AZD1222 vaccine. Histopathological ex- aminations revealed cellular interface dermatitis. The patient was diagnosed with general- ized LP and was successfully treated with systemic corticosteroid and cyclosporine. As the vaccination campaign against COVID-19 is ongoing and early recognition and treatment are essential to reduce the morbidity of this condition, clinicians should be aware that LP could follow COVID-19 vaccination regardless of the type of vaccine administered.

This study was conducted to review data utilization plans and suggest solutions based on the need for tools that can objectively diagnose problems in rural areas. The study extracted items through prior research and was carried out as a process of reviewing data capable of constructing spatial data. The results performed in the above manner are as follows. First, prior research and expert surveys were conducted to select diagnostic items to derive details of a total of three items that should be considered for rural space plans such as regional revitalization and regeneration using regional characteristics such as environment, society, and culture. Second, as a result of listing data available for regional diagnosis, 6 types of environment, 15 types of society, and 18 types of culture were selected out of a total of 529. Finally, it was suggested to establish a national standard spatial unit by grasping the limitations of public data such as omission of spatial data and accuracy. This study is significant in that it presented implications for data utilization as well as selection of items for rural diagnosis and reviewed data utilization based on rural specialized districts of "The Act on Support for Restructuring and Regeneration of Rural Spaces" to be implemented in 2024. This is considered to be valuable as a study for sustainable rural diagnosis if processes such as spatial data construction and weight setting are carried out in the future.

This study conducted a big data analysis targeting the concept of "Ruralism," which is important in rural development, and the keywords "Rurality" and "Rural-amenity," which are similarly used. Keyword frequency analysis, key keyword analysis, network analysis, and emotional analysis were conducted by applying text mining techniques, which are methods of analyzing unstructured data online, to present basic data on the establishment of the concept of Ruralism for rural space maintenance. As a result of the study, conservation for Ruralism was the most important in the case of keyword frequency analysis, and differences between the Rurality and Rural-amenity keywords, which were used similarly to Ruralism, were identified through major keywords, indicating that Ruralism is a concept that has a more comprehensive range of rural areas than other concepts. In the case of the network, the network shown in Ruralism was prominent in improving the quality of life of invisible residents, and the last emotional analysis showed that it was necessary to prepare standards to overcome the possibility of preserving Ruralism and difficult policy directions. This study is meaningful in that it identifies online perceptions and looks at them from a macro perspective so as not to be confused by looking at keywords used similarly to Ruralism at a time when setting mid- to long-term policy directions is important.
