This study proposes a mobile application service design that can enhance communication between grandparents and adult children who share parenting responsibilities. Based on a double diamond design process, we conducted case studies by examining existing applications for co-parenting and communication enhancement programs to identify and retrieve key elements/factors in need of improvement. We completed in-depth interviews on three co-parenting grandparent and adult child dyads. With functions selected based on the collected data, the final version of the prototype was developed into a feasible application, which was utilized for user evaluation and collecting of feedback from target users.

Study of ion beam shaping of an anode-type ion source coupled with a Whenelt mask

허윤성,황윤석,김제하 한국진공학회 2018 Applied Science and Convergence Technology Vol.27 No.4

We fabricated an anode-type ion source driven by a charge repulsion mechanism and investigated its beam shape controlled by a Whenelt mask integrated at the front face of the source. The ion beam shape was observed to vary by changing the geometry of the Whenelt mask. As the angle of inclination of the Whenelt mask was varied from 40 to 60, the etched area at a thin film was reduced from 20 mm to 7.5 mm at the working distance of 286 mm, and the light transmittance through the etched surface was increased from 78% to 80%, respectively. In addition, for the step height difference,  between the inner mask and the outer mask of  = 0, -1 mm, and +1 mm, we observed the ion beam shape was formed to be collimated, diverged, and focused, respectively. The focal length of the focused beam was 269 mm. We approved experimentally a simple way of controlling the electric field of the ion beam by changing the geometry of the Whenelt mask such that the initial direction of the ion beam in the plasma region was manipulated effectively.

본 연구에서는 금속 칼날 마스크와 펄스형 레이저 증착장치를 이용하여 $YBa_2Cu_3O_{7-\delta}$/$SrTiO_{3}$/$YBa_2Cu_3O_{7-\delta}$ 다층박막 형태의 In-situ SIS ramp dege 형태의 접합을 제작하였으며, 이의 특성을 조사하였다. 접합은 RSJ 형태의 전류-전압 특성ㅇ르 나타내고 있으며, 온도 변화에 따른 접합의 normal resistance는 약 $18 \omega$으로 온도에 무관하게 일정한 값을 나타내었다. 접합형태를 이용하여 감도(transfer function, dV/$d\Phi$)가 약 $22\mu$V/$\Phi_{0}$인 dc-SQUID센서를 제작하였으며, in-situ SIS ramp edge 형태의 접합이 센서로의 응용가능성을 충분히 가지고 있음을 보여 주었다. In this study, we have fabricated in-situ multilayer $YBa_2Cu_3O_{7-\delta}$/$SrTiO_{3}$/$YBa_2Cu_3O_{7-\delta}$ ramp edge type junctions by using a metal mask and pulsed laser deposition method and studied the junction properties. The junctions showed RSJ-like I-V characteristics. The normal state junction resistance R, of $18 \omega$ was nearly constant with temperature. The dc-SQUID sensors fabricated with the junctions show a sensitivity that transfer function dV/$d\Phi$)~$22\mu$V/$\Phi_{0}$, indicating that the in-situ ramp edge type junction is potentially useful for sensor application.

Characteristics of critical pressure for a beam shape of the anode type ion beam source

허윤성,황윤석,김제하 한국진공학회 2018 Applied Science and Convergence Technology Vol.27 No.4

We studied the critical pressure characteristics of an anode type ion beam source driven by both charge repulsion and diffusion mechanism. The critical pressure Pcrit of the diffusion type ion beam source was linearly decreased from 2.5 mTorr to 0.5 mTorr when the gas injection was varied in 3~10 sccm, while the Pcrit of the charge repulsion ion beam source was remained at 3.5 mTorr. At the gas injection of 10 sccm, the range of having normal beam shape in the charge repulsion ion beam source was about 6.4 times wider than that in the diffusion type ion beam source. An impurity of Fe 2p (KE = 776.68 eV) of 12.88 at. % was observed from the glass surface treated with the abnormal beam of the charge repulsion type ion beam source. The body temperature of the diffusion type ion beam source was observed to increase rapidly at the rate of 1.9 °C/min for 30 minutes and to vary slowly at the rate of 0.1 °C/min for 200 minutes for an abnormal beam and normal beam, respectively.

`Purpose: To evaluate the clinical aspects of severe endogenous endophthalmitis requiring evisceration, particularly underlying disease, causative microorganisms, and infection focus, and to assess the outcome of evisceration. Methods: The records of 13 patients who were diagnosed with endogenous endophthalmitis requiring evisceration and treated at Yeungnam University Hospital from July 1994 to April 2007 were retrospectively reviewed. Results: Of the 13 patients, all patients had diabetes mellitus, five had advanced liver disease, and one had aplastic anemia. Infection foci were pyelonephritis, pneumonia, and liver abscess. Five cases were confirmed with positive culture of Klebsiella pneumoniae. Ten cases underwent evisceration with hydroxyapatite implantation, and three cases were treated conservatively because the patient was in poor systemic condition. Of the 10 patients who underwent evisceration, ocular implants were exposed in five cases. Conclusions: This study suggests that evisceration with primary orbital implant insertion for endogenous endophthalmitis involves the risk of implant exposure, but after secondary repair, all patients have stable clinical courses. `

This study attempted to examine consumers' awareness of the safety of cosmeceuticals and analyze harmful ingredients against high school girls who have recently emerged as a new consumer group in the cosmeceutical market with a goal of providing basic data needed to buy cosmeceuticals by investigating their consumption patterns and satisfaction with the cosmetic products. For this, an online questionnaire survey was performed against a total of 377 high school girls born in 2003-2005 in Seoul and Gyeonggi-do. The collected data were analyzed, using IBM SPSS Statistics 20, and the results found the followings: The respondents' awareness of the safety of cosmetics was neither high nor low while awareness of harmful ingredients was high. Among cosmeceuticals, it was sunscreens acnecare products that they have bought frequently. As their awareness of the safety of cosmetics was higher, they tended to check the effects and efficacies of ingredients. Depending on their skin concerns, they planned and bought the cosmeceuticals they needed by comparing their information. In addition, they have examined cosmetic information through apps and web portals in consideration of the efficacies and effects of cosmeceuticals and their skin type and conditions. Concerning cosmeceutical use patterns by the awareness of harmful ingredients, the perception of the hazard of synthetic color additives, synthetic flavors and mineral oil had an influence on the use of cosmeceuticals. Depending on the awareness of the safety and harmful ingredients of cosmetics, furthermore, the respondents were more satisfied with the cosmeceuticals. Under these circumstances, it is required to provide accurate information about cosmetic ingredients and help consumers have a better awareness of the safety of cosmetics by developing and distributing educational programs on harmful ingredients and decent contents
