이경선 ( Lee¸ Gyeong-seon ) 한국아동교육학회 2021 아동교육 Vol.30 No.4

본 연구는 코로나19 상황에서 유아안전에 관한 사회적인 인식을 빅데이터 분석 방법인 의미연결망 분석을 통해 살펴보고 향후 또 다른 감염병 등의 재난상황에서 효율적인 유아 안전 대응체계의 방향을 제시하는데 목적이 있다. 이를 위해 ‘코로나19+유아+안전’을 검색어로 하여 코로나가 발생한 시기인 2020년 1월 1일부터 연구시점인 2021년 6월 30일까지 18개월간 온라인 텍스트를 수집하였다. 웹 기반의 빅데이터 분석 솔루션인 텍스톰을 활용하여 테이터 수집과 2차례의 데이터 정제를 실시하였고, 최종 50개의 핵심 키워드를 선정하였다. 키워드의 TF-IDF와 빈도를 바탕으로 의미연결망을 구성하여 중심성 분석과 CONCOR 분석을 실시하였다. 연구결과 첫째, ‘코로나’, ‘유아’, ‘안전’, ‘영아’, ‘유아교육기관’ 등의 키워드가 가장 큰 중요성과 영향력을 가진 것으로 나타났다. 둘째, CONCOR 분석 결과 총 4개의 군집이 형성되었다. 군집별 키워드들의 내용을 참고하여 ‘유아교육기관의 대응과 정보’, ‘원격 수업’, ‘코로나 지원’, ‘영아’ 등으로 명명하였다. 이를 토대로 향후 자연재해나 전염병 확산 등의 재난상황에서 유아안전에 필요한 대응체계의 개선 방향을 제시하였다. The purpose of this study was to analyze keywords relatede to preschooler safety through informal big data. For this purpose, big data on preschooler safety were defined as a collection of web-based text documents via the online channel Naver and Daum for the COVID-19 period. Specifically, a total of 21,485 articles and blog texts were collected using the search terms ‘COVID-19+preschooler+safety’. Subsequently, the top 50 keywords were selected based on TF-IDF, formed a semantic network, and identified major keywords through centrality and CONCOR analysis through UCINET6 and NetDraw programs. The results show that the keywords with highest centrality was ‘COVID-19’, ‘safety’, ‘preschooler’, ‘early childhood education’, ‘infant’ etc. The results of this study imply the importance of early childhood education institution related to preschooler safety. According to CONCOR analysis, four major keywords were identified: ‘information and response of early childhood education institution’, ‘distance education’, ‘support for COVID-19’ and ‘infant’. Based on this, the plans for preschooler safety and policy improvement in the future disaster should be considered.

In this globalizing age of the world, renewed and comprehensive concepts of tourism is being required in the field of tourism as well as in every other aspects of the social phenomena. Routine ways of tourism only to visit historical sites enjoying special foods can no longer attract tourists with diversified needs to fulfill their curiosities. Among others, culture tourism has already been proved to some degree to satisfy tourists' more advanced and diversified needs. It can be suggested that mural paintings be in this ground, as a strong means of enhancing cultural tourism. Culture is the product of a specific society in which people share similar values, similar ideas, and similar ways of behavior. And understanding other cultures has already been highlighted in attracting diversified needs of tourists. To survive and to be competitive in the tourism market, more extended and detailed cultivation in this field of culture tourism has been seriously developed. And mural paintings might open a new horizon to accelerate a competitive tourism. The mural paintings as an artistic genre which can satisfy such cultural characteristics have enough potential to be developed into the resources of the cultural tourism. There is an example that the work of the mural paintings, which is highlighted with the biggest outdoor gallery on earth, based on history and tradition of the city changed the dull image of the city to be culturally attractive. Mural paintings impling cultural images representing history and tradition of the specific place would be sure to raise emotional sympathy and unity of the citizen, thereby contributing to an efficient tourism and strengthened pride of their city. Advanced countries have already witnessed the necessity of the new economic development based on the service industry and started to develop cultural industry. In the age of cultural competition, it is highly required to be distinctive and different from other cultures. From this standpoint, this study lay its heavy focus on differentiation between mural paintings based on culture as a new resource of cultural tourism. Unfortunately, Korea has not yet witnessed any example for the purpose of cultural tourism. This study, in this respect, is desired to be a guide to enhance a more developed type of tourism to satisfy diversified expectations of the tourists, thus surviving in the tough intemational tourism market.

보육교사의 직무자율성과 혁신행동 관계에서 잡 크래프팅의 매개효과

이정화(Jeonghwa Lee),이경선(Gyeongseon Lee) 한국문화융합학회 2023 문화와 융합 Vol.45 No.12

본 연구의 목적은 보육교사의 직무자율성과 혁신행동의 관계를 규명하고, 이들의 관계에서 잡 크래프팅의 매개효과를 분석하는데 있다. 이를 위해 부산광역시에 재직하고 있는 보육교사 261명의 설문지자료를 수집하여 상관관계, 구조방정식 모형분석, Bootstrapping을 실시하였다. 본 연구 결과는 다음과 같다. 첫째, 직무자율성과 잡 크래프팅, 혁신행동의 상관관계는 모두 유의한 정적 관계가 있는 것으로 확인되었다. 둘째, 보육교사의 직무자율성은 잡 크래프팅과 혁신행동에 유의한 정적 영향을 미치며, 잡크래프팅은 혁신행동에 유의한 정적 영향을 미치는 것으로 나타났다. 셋째, 직무자율성과 혁신행동 관계에서 잡 크래프팅의 매개효과가 검증되었다. 이러한 연구결과를 토대로 보육교사의 직무자율성과 잡크래프팅이 발휘될 수 있는 지원 방향을 논의하였다. The purpose of this study is to investigate the mediating effects of job crafting on the relationship between job autonomy and innovative behavior perceived by childcare teachers. For this purpose, we collected data by surveying 261 chidcare teachers working in the city of Busan. The collected data was analyzed using SPSS 25.0 and AMOS 22.0. The results of this study are as follows. First, we found significant positive relationships among the job autonomy, job crafting, and innovative behavior. Second, we observed that childcare teachers' job autonomy had a significant positive effect on job crafting and innovative behavior, and job crafting had a significant positive effect on innovative behavior. Third, we confirmed that job crafting has a significant mediating effect in the relationship between job autonomy and innovative behavior. Based on these research results, we discussed ways to support childcare teachers' job autonomy and job crafting.

Pulsed-Laser-Induced Simple Synthetic Route for Tb ₃ Al ₅ O ₁₂ :Ce ³⁺ Colloidal Nanocrystals and Their Luminescent Properties

<P>Cerium-doped Tb<SUB>3</SUB>Al<SUB>5</SUB>O<SUB>12</SUB>(TAG:Ce<SUP>3+</SUP>) colloidal nanocrystals were synthesized by pulsed laser ablation (PLA) in de-ionized water and lauryl dimethylaminoacetic acid betain (LDA) aqueous solution for luminescent bio-labeling application. The influence of LDA molecules on the crystallinity, crystal morphology, crystallite size, and luminescent properties of the prepared TAG:Ce<SUP>3+</SUP>colloidal nanocrystals was investigated in detail. When the LDA solution was used, smaller average crystallite size, narrower size distribution, and enhanced luminescence were observed. These characteristics were explained by the effective role of occupying the oxygen defects on the surface of TAG:Ce<SUP>3+</SUP>colloidal nanocrystal because the amphoteric LDA molecules were attached by positively charged TAG:Ce<SUP>3+</SUP>colloidal nanocrystals. The blue-shifted phenomena found in luminescent spectra of the TAG:Ce<SUP>3+</SUP>colloidal nanocrystals could not be explained by previous crystal field theory. We discuss the 5d energy level of Ce<SUP>3+</SUP>with decreased crystal size with a phenomenological model that explains the relationship between bond distance with 5d energy level of Ce<SUP>3+</SUP>based on the concept of crystal field theory modified by covalency contribution.</P>

제네릭 의약품의 국가 간 약가 비교: 분석방법별 약가 수준의 차이 고찰

배은미 ( Eun-mi Bae ),최상은 ( Sang-eun Choi ),강대원 ( Daewon Kang ),신경선 ( Gyeongseon Shin ) 한국보건경제정책학회(구 한국보건경제학회) 2021 보건경제와 정책연구 Vol.27 No.2

외국과의 약가 비교연구는 사용된 방법에 따라 다양한 결과를 보이는 것으로 알려져 있는데, 본 연구는 2016년 기준 우리나라와 외국 15개국의 제네릭 약가수준을 여러 분석방법을 사용하여 비교하였다. 외국 약가 자료원은 Parma Price Information (PPI)과 일본 노동후생부 관보를 사용하였고, 건강보험청구금액을 기준으로 상위 성분 중, 제네릭이 존재하면서 비교국가가 3개국 이상 존재하는 정제 23개 성분을 대상으로 하여, 대상 국가와 1:1 비교하였다. 연구결과 우리나라 제네릭 의약품의 약가수준은 분석조건에 따라 다소 차이가 있었지만, 전반적으로 외국에 비해 높은 것으로 나타났다. 외국과 달리 우리나라에서 제네릭 약가는 브랜드의 약품과 비슷한 수준에서 형성되어 있고, 제네릭 출시 시기, 제네릭 점유율, 경쟁품목 수 등은 제네릭 약가 수준에 영향을 미치지 않는 것으로 나타났다. 본 연구의 분석방법 중 결과에 영향을 크게 미치는 것은 비교국가 선정과 사용량 가중치, 그리고 가격유형이었다. To investigate generic drug price levels in Korea, we conducted a cross-national drug price comparison. Also, it was investigated whether the price level could differ when the price comparison method was changed. Parma Price Information (PPI) and Ministry of Health, Labor and Welfare (MHLW) official gazettes were used for 14 European countries and Japan respectively. Bilateral comparisons with 15 countries were conducted for the top 23 molecules based on health insurance claims data. As a result, the price level of generic drugs in Korea was slightly different depending on the method, but it was overall higher than that of comparison countries. The weighted average price of generics was similar to that of the brand, and none of the launch date, the market share, and the number of competing items appear to affet the drug price level. This study has demonstrated the sensitivity of cross-national drug price comparisons to the methods used, including comparison countries, weights, and price type.
