다공성 실리콘을 근거한 실리콘 양자점을 이용한 휘발성 알콜 증기의 감지
조보민, 엄성용, 진성훈, 최태은, 양진석, 조성동, 손홍래 조선대학교 기초과학연구원 2010 조선자연과학논문집 Vol.3 No.2
Silicon quantum dots base on photoluminescent porous silicon were prepared from an electrochemical etching of ntype silicon wafer (boron-dopped<100> orientation, resistivity of 1~10 Ω-cm) and used as a alcohol sensor. Silicon quantum dots displayed an emission band at the wavelength of 675 nm with an excitation wavelength of 480 nm. Photoluminescence of silicon quantum dots was quenched in the presence of alcohol vapors such as methanol, ethanol, and isopropanol. Quenching efficiencies of 21.5, 32.5, and 45.8% were obtained for isopropanol, ethanol, and methanol, respectively. A linear relationship was obtained between quenching efficiencies and vapor pressure of analytes used. Quenching photoluminescence was recovered upon introducing of fresh air after the detection of alcohol. This provides easy fabrication of alcohol sensor based on porous silicon.

Background: Recently, ‘subscription’ has emerged as a new consumption pattern in the online market, and the subscription economy market is rapidly expanding. As a result, companies induce membership in a simple way, but the dark pattern design method, which intentionally complicates termination, is prevalent. Therefore, this study attempts to examine the user experience according to the degree of complexity of the subscription termination process by focusing on the dark pattern recognition process. Methods: This study investigates the degree of discomfort of users according to the degree of complexity of the subscription termination process. The cancellation process of 50 domestic subscription services was analyzed and a total of seven types of cancellation were derived. Through this, specific functional strategies and dark pattern design patterns for each type were found. Accordingly, seven prototypes were produced for each type and user experiments, surveys, and interviews were conducted. Results: Depending on the degree of complexity of the subscription cancellation process, there were significant differences in dark pattern design perception, degree of discomfort, and intention to resubscribe regarding user experience. It has been found that users also recognize dark pattern design at points where they feel uncomfortable. In addition, even though it is the same functional strategy, there was a difference in the level of discomfort according to the degree of complexity and dark pattern design intervention. Such discomfort in the experience of unsubscribing affects the intention to resubscribe and further negatively affects the image of the company. Conclusions: This study attempts a dark pattern design study that can be applied universally to various types of subscription services, and in particular, it was found that among the seven types, the ‘repetitive benefit proposal type’ expresses the intention to resubscribe despite dark pattern design recognition. It is expected that the user experience of the subscription service will be improved through design direction suggestions suitable for both users and companies.

DBR 다공성 실리콘과 Host 다공성 실리콘으로 이루어진 이중 다공성 실리콘의 제조와 광학적 특성
최태은, 양진석, 엄성용, 진성훈, 조보민, 조성동, 손홍래 조선대학교 기초과학연구원 2010 조선자연과학논문집 Vol.3 No.2
DBR/Host dual porous silicons containing DBR and host structure were prepared and their optical properties were characterized using Ocean Optics spectrometer. In this dual porous silicon, single porous silicon layer was used as host layer for possible biomolecule and drug materials and DBR porous silicon layer was used for signal transduction due to the recognition of molecules. Optical reflection spectrum of dual porous silicon displayed only DBR reflection but Fabry- Perot fringe pattern. DBR reflection band of dual porous silicon shifted to the shorter wavelength as the etching time of host layer increased. Cross-sectional FE-SEM image of dual porous silicon displayed a thickness of about 20 micrometer for DBR porous silicon layer. Developed etching technology could be useful to prepare DBR porous silicon which exhibited specific reflection resonance at the required wavelength and to provide an label-free biosensors and drug delivery materials.

2,5-Difunctioanl silole의 합성과 광학적 특성
최태은, 양진석, 한정민, 엄성용, 진성훈, 조보민, 조성동 조선대학교 기초과학연구원 2009 조선자연과학논문집 Vol.2 No.1
New functionalized siloles have been synthesized and their optical characterizations are investigated. Silole unit has been interested, since silole has a unique optical and electronic properties. Here we report the synthesis of new type of photoluminescent silole. New siloles have been characterized by NMR, FTIR, and UV-vis absorption spectroscopy. Their optical characteristics have been also investigated using photoluminescence spectroscopy. Possible applications such as OLED and chemical sensors will be presented.
