공공장소의 디지털 사이니지를 활용한 N-Screen 서비스 개발 방향 : 버스정류장에서의 개인화된 컨텐츠 이용에 관한 시나리오 제안
고소연(Soyeon Ko),박남춘(Namchoon Park) 한국HCI학회 2012 한국HCI학회 학술대회 Vol.2012 No.1
N-screen은 하나의 멀티미디어 콘텐츠를 N개의 스크린에서 연속적으로, seamless하게 즐길 수 있는 기술 또는 서비스를 말한다. N-screen 서비스는 콘텐츠 제공 비즈니스에 있어서 서비스 스크린 확대와 시장의 확장 측면에서 매우 매력적인 서비스로 조명 받고 있다. 하지만 현 N-screen 서비스는 개인 소지 단말기만을 대상으로 한정시켜, 다양하고 폭넓은 N-screen 활용 가능성을 제한시키고 있다. 본 논문에서는 개인 소지 단말기 중심에 국한되었던 N-screen 개념을 넘어서서 공공장소의 다양한 스크린들까지 포괄하는 확장된 개념의 N-screen 서비스를 제안한다. 광의의 N-screen 개념을 설명하기 위해 특정 공공장소를 버스정류장으로 설정하고, 버스정류장의 디지털 사이니지와 개인의 모바일 단말의 자유로운 연동을 통한 콘텐츠 이용 시나리오를 제시한다. 시나리오는 콘텐츠 제공, 전달 및 공유, 소비 및 이동에 초점을 맞추어 개발되었으며, 공공 미디어를 통한 개인화된 인터랙션과 타 기기/ 타 공간으로의 자유로운 콘텐츠의 이동 및 전달을 목적으로 한다. 시나리오 상에서 공공장소의 스크린들은 다양한 콘텐츠들이 공유되는 storage의 역할을 하고, 사용자는 개인의 모바일 단말을 활용하여 직접 콘텐츠 유통 과정에 참여할 수 있다. 제안하는 시나리오는 여타의 공공장소에 다양하게 적용될 수 있으며, 발전된 N-screen 환경 구축 가능성과 함께 다양한 스크린을 활용한 콘텐츠 제공 및 소비 형태에 대한 가능성을 보여줄 것이다. N-screen means the technology or service that we can enjoy one multimedia contents seamlessly in series on N screens. In the contents providing business, N-screen service is focused as a service which is very attractive from the aspect of service screen expansion and market expansion. But, the current N-screen service limits various and wide application possibilities of N-screen by restricting the object to only individual mobile phone. This thesis suggests N-screen service which has expanded concepts including public place's various screens beyond the concept of N-screen limited to individual mobile phone. For explaining the wide sense of N-screen concept, it sets special public place as bus stop and suggests the contents using scenario through the free linkage between digital signage of bus stop and individual mobile phone. The scenario was developed by focusing on contents provision, delivery and sharing, consumption and moving as well as its purposes are personalized interaction by public media and free delivery and moving of contents to other mobile phones/ other places. The suggested scenario can be applied to other public places variously and it will show possibility to establish environment of developed N-screen, provision of contents applying various screens and possibility for consumption pattern.

The natural flavonoid macakurzin C (1) exhibited adiponectin biosynthesis-inducing activity during adipogenesis in human bone marrow mesenchymal stem cells and its molecular mechanism was directly associated with a pan-peroxisome proliferator-activated receptor (PPAR) modulator affecting all three PPAR subtypes α, γ, and δ. In this study, increases in adiponectin biosynthesisinducing activity by macakurzin C derivatives (2–7) were studied. The most potent adiponectin biosynthesis-inducing compound 6, macakurzin C 3,5-dimethylether, was elucidated as a dual PPARα/γ modulator. Compound 6 may exhibit the most potent activity because of the antagonistic relationship between PPARδ and PPARγ. Docking studies revealed that the O-methylation of macakurzin C to generate compound 6 significantly disrupted PPARδ binding. Compound 6 has therapeutic potential in hypoadiponectinemia- related metabolic diseases.

Aim(s): There is a lack of research that has produced results on the relationship between nursing college students' nursing process performance, critical thinking disposition, and nursing information literacy competency. This study seeks to understand the impact of nursing college students' critical thinking disposition and nursing information literacy competency on nursing process performance. Method(s): The subjects of study are 180 students from the Department of Nursing at K University in E providence. Data collection took place from 17 August to 2 September 2020. The research tools used critical thinking disposition, NILC-N (Nursing Information Literacy Competency) tools, and nursing process performance tools. The collected data analysis used the SPSS/WIN 25.0 program, using technical statistics and Independent t-test, ANOVA, Pearson’s correlation coefficient method. Result(s): Critical thinking disposition is whether or not nursing courses are completed (121.79±16.28 vs 119.31±21.52, t=.842, p=.028) showed a difference depending on. Nursing information literacy competency differed between the first and second groups(83.93±16.15) and the third and fourth grade groups(99.04±12.18). Nursing information literacy competency differed depending on whether or not clinical practice was experienced(99.12±12.09 vs 83.65±16.09, t=7.177, p=.047) and Completion of nursing informatics course (65.78±9.57 vs 49.48±16.38, t=5.501, p=.015) showed differences. The study subjects’ nursing process performance showed a positive correlation between critical thinking disposition(r=.413, p<.001) and nursing information literacy competency(r=.769, p<.001). Conclusion(s): It was confirmed that the impact on nursing college students’ ability to nursing process performance was critical thinking disposition and nursing information literacy competency. In order to improve nursing college students' nursing process performance, it is necessary to develop educational programs that can foster nursing information literacy competency and critical thinking levels.
Enhanced Gas Sensing Properties of Bi2O3-Core/In2O3-Shell Nanorod Gas Sensors

The Bi2O3 nanowires are highly sensitive to low concentrations of NO2 in ambient air and are almost insensitive to most other common gases. However, it still remains a challenge to enhance their sensing performance and detection limit. This study examined the influence of the encapsulation of β-Bi2O3 nanorods with In2O3 on the NO2 gas sensing properties. β-Bi2O3-core/In2O3-shell nanorods were fabricated by a two-step process comprising the thermal evaporation of Bi2O3 powders and sputter-deposition of In2O3. Multiple networked β- Bi2O3-core/In2O3-shell nanorod sensors showed the responses of 12-156% at 1-5 ppm NO2 at 300 oC. These response values were 1.3-2.7 times larger than those of bare β-Bi2O3 nanorod sensors at 1-5 ppm NO2. The enhancement in the response of β-Bi2O3 nanorods to NO2 gas by the encapsulation by In2O3 can be accounted for based on the space-charge model.
Enhanced ethanol sensing properties of TeO2/In2O3 core-shell nanorod sensors
Hyunsung Ko,박성훈,Soyeon An,이종무 한국물리학회 2013 Current Applied Physics Vol.13 No.5
TeO2/In2O3 coreeshell nanorods were fabricated using thermal evaporation and sputtering methods. The multiple networked TeO2/In2O3 coreeshell nanorod sensor showed responses of 227-632%, response times of 50-160 s, and recovery times of 190-220 s at ethanol (C2H5OH) concentrations of 50-250 ppm at 300 ℃. The response values are 1.6-2.9 times higher and the response and recovery times are also considerably shorter than those of the pristine TeO2 nanorod sensor over the same C2H5OH concentration range. The origin of the enhanced ethanol sensing properties of the coreeshell nanorod sensor is discussed.

This study was to identify the current state and client satisfaction level together with service providers’ recognition and opinion of the community-based occupational therapy services in Gwangju. The survey study was conducted, from January 27th through March 14th in 2011, with 160 clients receiving occupational therapy services at public health centers and their branch offices in Gwangju. The results were as follows. Persons over 65 years old suffering from stroke wanted community based occupational therapy services more than other age groups. The service wanted most was about improving body functions. The client satisfaction was highest for permanent employees among permanent employees, temporary employees, and volunteers. The client satisfaction on facilities and equipments was relatively high except a couple of categories (transportation and new equipments). Service providers perceived that physical facilities and equipments were inadequate; human and financial resources were insufficient; education about professional knowledges and skills were inadequate; and they were in clients’s confidence.
유·무선 망에서의 오버레이 멀티캐스트 프로토콜 통합 방안

유선 네트워크와 애드 혹 무선 네트워크의 기본적인 차이점인 제한적 대역폭, 파워 등으로 인해 두 네트워크 사이에 멀티캐스트를 하고자 할 때, 한 멀티캐스트 프로토콜을 다른 네트워크네 적용 시키는 것은 비효율적이다. 서로 다른 네트워크 환경의 멀티캐스트를 통합하기 위한 방안으로 몇 가지 멀티캐스트 게이트웨이가 연구되었다. 기존의 멀티캐스트 게이트웨이는 멀티캐스트 그룹에 참여하기를 원하는 노드가 다른 환경의 멀티캐스트 그룹에 참여할 때마다 컨트롤 메시지의 전환이나, 패킷 헤더의 변경을 요구한다. 이와 달리, 본 논문에서 제안하는 멀티캐스트 게이트웨이는 애드 혹 노드가 유선 네트워크의 오버레이 멀티캐스트 그룹에 참여하고자 할 때에는 애드 혹 수신자 노드의 대리 송신자 역할을 하며 반대로 유선 네트워크 노드가 애드 혹 멀티캐스트 그룹에 참여하고자 할 때에는 유선 네트워크 수신자 노드의 대랴 송신자 역할을 담당한다. 따라서 애드 혹 네트워크의 노드가 직접 오버레이 멀티캐스트 그룹에 참여할 때 또는 오버레이 네트워크의 노드가 직접 애드 혹 멀티캐스트 그룹에 참여할 때 복잡한 멀티캐스트 프로토콜의 전환 과정을 생략할 수 있고, 투명성을 제공할 수 있다.
