Recently, three-dimensional (3D) light harvesting structures are highly attracted because of their high light harvesting capacity and charge collection efficiencies. In this study, we have fabricated Cu₂ZnSn(SxSe1-x)₄ based 3D thin film solar cells on PR patterned Molybdenum (Mo) substrates using photolithography technique. Specifically, Mo patterns were deposited on PR patterned Mo substrates by sputtering and the thin Cu-Zn-Sn stacked layer was deposited over this Mo patterns by sputtering technique. The stacked Zn-Sn-Cu precursor thin films were sulfo-selenized to form CZTSSe pattern. Finally, CZTSSe absorbers were coated with thin CdS layer using chemical bath deposition and ZnO window layer was deposited over CZTSSe/CdS using DC sputtering technique. Fabricated 3-D solar cells were characterized by X-ray diffraction (XRD), X-ray fluorescence (XRF) analysis, Field-emission scanning electron microscopy (FE-SEM) to study their structural, compositional and morphological properties, respectively. The 3% efficiency is achieved for this kind of solar cell. Further efforts will be carried out to improve the performance of solar cell through various optimizations.

한국 관광안내표지 관련 가이드라인은 2009년, 두 차례에 걸쳐 발표되었으며, 2019년에는 개편되어 발표되었음에도 불구하고 최근 각 광역 및 기초자치단체들은 이 가이드라인을 활용하기 보다는 지역의 특성을 표현할 수 있는 새로운 가이드라인을 제작하여 활용하고 있는 상황이다. 본 연구는 이와 같은 상황에 대한 문제제기를 통해 한국 관광안내표지 구성요소의 실태를 분석하고 문제점을 도출하여 해결 방향을 제시해보고자 하였다. 더구나 한국 관광안내표지 가이드라인 관련 연구 역시 드문 현 상황에서 우리는 한국 관광안내표지 가이드라인의 활용도를 높이기 위하여 시각기호학적 관점을 도입하고 종합관광안내표지를 대상으로 그 시각적 구성요소를 분석해보고자 시도하였다. 분석 결과, 2019년 가이드라인에서 개편된 구성요소는 소수에 불과하며 이 역시 의미적 측면의 고려는 이루어지지 않고, 정보 제공의 측면만을 강조하여 실용적 가치 부여에 초점을 두고 있음을 파악하였다. 그러나 관광안내표지는 지역의 특성을 반영하여 정체성을 드러내야 한다는 점에서 유토피아적 가치 부여 또한 고려되어야 한다. 이와 같은 가이드라인의 개선을 위해 본 연구는 이항 대립 분석과 선, 형태, 공간성, 질감과 같은 조형적 기호의 분석을 실시하여 다른 관광안내표지와 비교하였을 때 차별적 요소로 작용할 수 있는 가이드라인의 구체적인 시각화 방향성을 제안할 수 있었다. The guidelines related to Korea's tourist information signs were issued twice in 2009, and although they were revised and announced in 2019, metropolitan city and regional governments have recently created and used new guidelines that can express the characteristics of the region rather than using these guidelines. This study attempted to analyze the actual conditions of the components of Korean tourist information signs by drawing out a problem in such a situation, and to identify problems and suggest solutions. In addition, in the current situation where research related to the guidelines on Korean tourist guide signs are rare, we introduced a visual semiotic perspective to increase the utilization of the guidelines, and tried to analyze the visual components of tourist information boards. As a result of the analysis, it was found that only a few components were reorganized in the guidelines in 2019, and this also did not consider the semantic aspect, but focused on the provision of practical value by emphasizing only the aspect of information provision. However, in that tourist information signs should reflect the characteristics of the region and reveal their identity, it is also necessary to consider giving utopian value. In order to improve the guidelines, this study analyzed the binary opposition and the plastic components of signs such as lines, forms, spaces, and textures and suggested a direction for visualization.

Purpose: The purpose of this study is to develop educational material for parents of hospitalized preschool children who receive nebulizer therapy treatment. The educational material is aimed at providing information on the correct use of nebulizer. Methods: The development of educational material was based on the ADDIE model and consists of an A4-sized leaflet and a video. Results: The leaflet included basic information, procedures, and cautionary information for nebulizer therapy, as well as frequently asked questions. The one minute and fifty second video is accessed via QR code and provides step-by-step instruction on nebulizer therapy. Conclusion: This study recommends that the educational leaflet and video developed for nebulizer therapy use be provided to parents of preschool children hospitalized in the pediatric ward.

본 연구는 어머니의 기본심리욕구와 한계설정 양육행동이 유아의 의도적 통제에 미치는 영향에 있어 유아 성별의 조절된 매개효과를 검증하기 위한 목적으로 수행되었다. 연구대상은 만 4, 5세 자녀를 둔 어머니 434명으로, 온라인 설문지에 응답하는 방식으로 자료를 수집하였다. 수집된 자료는 PROCESS macro의 모델 4와 15를 활용하여 매개효과와 조절된 매개효과를 분석하였다. 그 결과 어머니의 기본심리욕구에 해당하는 자율성, 유능성 및 관계성은 유아의 의도적 통제에 직접적인 영향을 미치는 것으로 나타났다. 또한 어머니의 한계설정 양육행동은 어머니의 기본심리욕구가 유아의 의도적 통제에 미치는 영향을 매개하여, 부분매개모형이 지지되었다. 마지막으로 어머니의 기본심리욕구와 한계설정 양육행동이 유아의 의도적 통제에 미치는 영향에 있어서 유아 성별의 조절효과는 나타나지 않았다. 이와 같은 본 연구의 결과는 유아의 의도적 통제 발달에 있어서 유아의 성별과 관계없이 어머니의 기본심리욕구와 한계설정 양육행동이 중요함을 시사한다. The purpose of the study is to examine whether maternal limit-setting parenting mediates the effects of their mother s basic psychological needs on the effortful control of their child aged 4 or 5. Also, moderating effects of children s gender on the paths from maternal basic psychological needs and limit-setting parenting to children s effortful control were examined. The subjects of the study were 434 mothers who participated in the on-line questionnaire. The collected data were analyzed using SPSS 22.0 and SPSS PROCESS macro 4.0. The results of the study are as follows. First, the PROCESS macro model 4 and 15 analyses showed that mother s basic psychological needs have a direct effect on their child s effortful control. Second, mother s limit-setting parenting behaviors partially mediate the effect of mother s basic psychological needs on their child s effortful control. Third, there was no moderating effect of child s gender on the influences of the mother s basic psychological needs and the limit-setting parenting behavior on their child s effortful control. This study shows that the mother s basic psychological needs and limit setting parenting behaviors are important in the effortful control development of young children, regardless of their gender.

Purpose : The purpose of this study was to identify whether static and dynamic balance in young men were influenced by the different height of insoles in their shoes. Methods : Eighteen healthy young men (mean 20.61±1.38 years) were recruited for this study. The subjects’ static and dynamic balance were assessed while wearing three different height’ insoles (0cm, 2cm, 3cm) in their tennis shoes. Anterioposterior (AP) and mediolateral (ML) sway velocity was measured for 20 seconds using a force plate (Good balance system, Finland) under four conditions including normal standing with eyes open and with eyes closed, and tandem standing with eyes open and with eyes closed. The Functional Reach Test (FRT) and Timed Up & Go (TUG) were also performed for each subject under each condition. Results : 1) ML and AP sway velocities in young men were significantly different according to the height of the insole in normal standing with eyes open and eyes closed. 2) ML and AP sway velocities in young men were not different according to the height of the insole in tandem standing with eyes open. 3) ML sway velocities in young men were significantly different according to the height of the insole in tandem standing with eyes closed, whereas AP sway velocities did not differ by height of the insole in tandem standing with eyes closed. 4) FRT scores in young men were significantly different according to the height of the insole. 5) TUG scores in young men were not significantly different according to the height of the insole. Conclusions : This study’s results indicate that the static and dynamic balance in young men can be influenced by shoe insole height.
