시장집중도를 이용한 바이오헬스산업의 지역개발격차 분석 및 시사점 - 충북지역을 중심으로 -

조예진,최상은 한국지역학회 2023 지역연구 Vol.39 No.2

본 연구는 공간적 범위가 다른 지역 간 개발격차를 파악하기 위해 산업조직론의 집중지수를 활용하여 실증적으로 분석하고 이를 통한 정책적 시사점 제안한다. 연구의 범위는 2000년대부터 현재까지 지속적으로 해당 산업을 육성해 온 충청북도 11개 시·군이며, 선행연구 고찰을 통해 지역개발격차지수 이론을 기반으로 상위기업집중률과 허핀달 지수를 이용하여 분석하였다. 연구대상은 전국 지자체가 경쟁적으로 육성 의지를 표명하고 있는 바이오헬스산업으로 대상지의 시·군경쟁력강화산업 결과를 기반으로 4개의 세부분야(제약, 의료기기, 건강기능식품, 화장품)로 나누어 연구를 수행하였다. 세부분야별 매출액, 종사자수, 연구개발비를 기준으로 분석한 지역개발격차지수 결과에 따라 지역별로 강점이 다른 것을 확인할 수 있었으며, 이 결과를 통해 향후 지역별 차별화된 산업육성 전략을 수립하는 데 기초자료로 활용될 수 있는 정책적 시사점을 도출하였다.

조예진,신미연,현명호 한국건강심리학회 2016 한국심리학회지 건강 Vol.21 No.3

본 연구는 현재 역경을 겪고 있는 사람들이 그 상황을 기회로 인식하고 있는지를 알아보기 위한척도로서 ‘역경 속의 기회 인식 척도(Perceived Opportunity in Adversity Scale; POAS)’를 개발하고 타당화 하는 데 그 목적이 있다. 이를 위해 20-50대 성인 17명을 대상으로 인터뷰를 실시하여 문항을 개발하였고, 440명을 대상으로 예비조사를 실시하였다. 문항 분석 및 탐색적 요인분석을 통해 4요인 17문항을 구성한 이후 230명을 대상으로 본 조사를 실시하였다. 문항 분석, 탐색적요인분석, 확인적 요인분석을 통해 통찰, 적극적 대처, 사고 전환, 인지적 지지, 정서적 지지로 구성된 최종 5요인 13문항을 도출하였다. 수렴 타당도를 확인하기 위해 기회 인식 능력 및 스트레스 대처 방식과의 상관관계를 분석하였으며, 공인타당도와 판별타당도를 확인하기 위해 회귀분석과 t검정을 실시하였다. 분석 결과 역경 속에서 기회를 인식한 사람과 그렇지 않은 사람은 역경후 성장에서 차이가 있었고, 역경 속에서 기회를 인식한 사람일수록 성장을 더 많이 하는 경향이있음을 확인하였다. 이러한 결과를 바탕으로 본 연구의 한계와 의의 및 후속연구에 대한 제언을논하였다. The purpose of this study was to develop and validate the 'Perceived Opportunity in Adversity Scale', which is used to determine whether people who experience adversity recognize the situation as an opportunity or not. The items were developed after conducting an interview on 17 adults in their 20s to 50s, and a pilot survey was conducted among 440 people. After composing 17 items in 4 factors through item analysis and exploratory factor analysis, the study was conducted on 230 people. A total of 13 items grouped in 5 factors including insight, active coping, thought switching, cognitive support, and emotional support were deduced through item analysis, exploratory factor analysis, and confirmatory factor analysis. Convergent validity was verified by correlation analyses of the POAS with opportunity recognition ability and stress coping method; in addition, concurrent and discriminant validity verified by regression analysis and t-test. The results indicated a significant difference in post-adversity growth between people who recognize opportunity in situations of adversity versus people who do not. Thus, people who recognize opportunity have a tendency to experience more growth. Based on these findings, research limitation, implication, and suggestion for future research were suggested.

This paper developed an artificial intelligence convergence project class for improving data literacy targeting elementary school students and verified its effectiveness. By analyzing the learner's actual conditions and needs and the 2022 revised elementary school curriculum, data literacy components suitable for the level of elementary school students and subjects and achievement standards that can form an artificial intelligence education program by converging them were selected. Based on this, after setting the subject of the project class, the overall goal and the detailed goal, the learning topic for each class and activities suitable for it were composed, and the class content was structured to design a total of 18 classes. Teaching and learning materials necessary for each class were developed, and an artificial intelligence convergence project class was conducted for one class in the 4th grade of elementary school. To compare the degree of improvement in data literacy, pre- and post-evaluation was conducted before and after application of the project class. According to the results of the analysis, it was found that the artificial intelligence convergence project class had a positive effect on the improvement of elementary school students' data literacy.

3차원 그래핀망으로 강화된 구리복합체의 전기전도도 연구

조예진,최병상,이창훈 한국물리학회 2022 새물리 Vol.72 No.1

Herein, a three-dimensional (3D) graphene–copper (3DiGn–Cu) composite was synthesized via chemical vapor deposition. The 3DiGn–Cu composite has a lesser electrical resistivity value than that of oxygen-free high-conductivity copper (OFHC Cu) under the same experimental conditions. To explain this behavior, the 3DiGn–Cu composite was considered as a parallel circuit comprising a graphene network channel(3DiGn) and a Cu network channel. Thus, the temperature dependence of the resistivity for 3DiGn–Cu and 3DiGn was measured. The measurement results show that the resistivity is proportional to temperature. Therefore, pure Cu powder can be reinforced by the 3D graphene network and the electrical conductivity can be improved up to that of OFHC Cu. 3차원 그래핀망으로 강화된 구리복합체 (3-dimensional graphene-copper composite; 3DiGn-Cu)를화학기상증착법으로 합성하였다. 3DiGn-Cu의 상온 비저항은 동일한 조건에서 OFHC Cu(oxygen-free high conductivity copper Cu) 의 값보다 더 작았다. 전기적관점에서 구리복합체를 3차원 그래핀망과 3차원 구리금속망이 병렬로 연결되어 만들어진 회로로 생각하였고, 구리복합체 전체의 비저항과3차원 그래핀망에 대한 비저항의 온도의존성을 각각 측정하였다. 두 채널 모두에서 비저항의 온도의존성 또한 금속물질과 비슷하게 온도에 비례하는 거동을 보였다. 결과적으로 구리입자를 3차원그래핀망으로 강화하였을 때 기계적 특성의 강화 뿐만아니라 전기적 특성도 개선될 수 있음을 알 수 있었다.

This study investigates early childhood teachers' perceptions and requirements concerning climate change education for young children, aiming to inform improvements and the development of early childhood climate change education programs. The research involved 356 early childhood teachers from Seoul and Gyeonggi regions, with data collected through online surveys and analyzed using SPSS 25.0. Qualitative analysis was applied to open-ended questions related to the definition of 'climate change.' Key findings include early childhood teachers demonstrating a robust awareness of climate change's gravity. However, they often perceive 'climate change' as primarily 'environmental destruction and natural disasters,' indicating a limited understanding of the concept. Despite 98.8% recognizing the need for early childhood climate change education, the implementation is challenged by high workloads and inadequate preparation time. Vital requirements for effective implementation include the development and distribution of materials suitable for young children's developmental stages and specific climate change educational resources for teachers. Teachers emphasize a proactive, practical educational approach that fosters understanding of climate change causes and impacts while promoting active responses and adaptation. Notably, even though over half of the teachers lacked prior climate change training, roughly 80% expressed intent to participate in future training. These findings lay the groundwork for discussions on early childhood climate change education and teacher training.

수계 Cu 나노입자 잉크에서 Poly(styrene-co-maleic acid) 접착 증진제가 잉크 레올로지와 인쇄패턴의 접착력에 미치는 영향

For a decade, solution-processed functional materials and various printing technologies have attracted increasingly the significant interest in realizing low-cost flexible electronics. In this study, Cu nanoparticles are synthesized via the chemical reduction of Cu ions under inert atmosphere. To prevent interparticle agglomeration and surface oxidation, oleic acid is incorporated as a surface capping molecule and hydrazine is used as a reducing agent. To endow water-compatibility, the surface of synthesized Cu nanoparticles is modified by a mixture of carboxyl-terminated anionic polyelectrolyte and polyoxylethylene oleylamine ether. For reducing the surface tension and the evaporation rate of aqueous Cu nanoparticle inks, the solvent composition of Cu nanoparticle ink is designed as DI water:2-methoxy ethanol:glycerol:ethylene glycol = 50:20:5:25 wt%. The effects of poly(styrene-co-maleic acid) as an adhesion promoter(AP) on rheology of aqueous Cu nanoparticle inks and adhesion of Cu pattern printed on polyimid films are investigated. The 40 wt% aqueous Cu nanoparticle inks with 0.5 wt% of Poly(styrene-co-maleic acid) show the "Newtonian flow" and has a low viscosity under $10mPa{\cdots}S$, which is applicable to inkjet printing. The Cu patterns with a linewidth of $50{\sim}60{\mu}m$ are successfully fabricated. With the addition of Poly(styrene-co-maleic acid), the adhesion of printed Cu patterns on polyimid films is superior to those of patterns prepared from Poly(styrene-co-maleic acid)-free inks. The resistivities of Cu films are measured to be $10{\sim}15{\mu}{\Omega}{\cdot}cm$ at annealing temperature of $300^{\circ}C$.
