As environmental problems accompanied by industrialization have emerged worldwide, solar and wind energy have entered the stage of commercialization, especially in Korea. In addition, research on improving aesthetics using solar cells is being actively conducted. Examples include developing a transmissive solar cell and developing a solar cell with flexibility and color. Therefore, in line with the upward trend of solar cell development and solar cell-based public facility installation, we will present guidelines for designing public facilities using solar cells to improve aesthetics. First of all, components were derived to increase the suitability of solar cell application through literature surveys on solar cells and case studies on public facilities using solar cells. Next, through prior research on public facility guidelines, we established evaluation principles and drafted design guidelines. Based on this, a Delphi survey was conducted on a group of experts to verify its validity. Design guidelines for solar cells application measures to improve the final public design aesthetics were derived. The goal is to improve the public facilities using solar cells, through Accessibility and cognition, Usability, Shape and aesthetics, Sustainability and energy efficiency, Continuity with the urban landscape. And it is expected that this data will be used to improve the aesthetics of public design using solar cells in the future. 산업화와 동반한 환경문제가 세계적으로 대두되면서 특히 우리나라에서는 태양에너지와 풍력에너지가 실용화 단계에 접어들었다. 또한 태양전지를 활용한 심미성 향상에 대한 연구가 활발히 이루어지는 가운데 BIPV, CIGS등 투과가 가능한 태양전지 개발, 유연성과 색감을 가지고 있는 태양전지 개발이 그 예시이다. 이에 본 논문에서는 태양전지 개발 및 태양전지 기반의 공공시설물 설치 상승세에 발맞춰 심미성 향상을 위한 CIGS 태양전지를 활용한 공공시설물 디자인 가이드라인을 제시하고자 한다. 우선 태양전지에 관한 문헌조사와 태양전지를 활용한 공공시설물 사례조사를 통해 태양전지 적용의 적합성을 높이기 위한 구성요소를 도출했다. 그 다음 공공시설물 가이드라인 선행연구를 통해 평가원칙 정립과 디자인 가이드라인 초안을 작성했다. 이를 전문가 집단을 대상으로 3차례의 델파이조사를 실시하여 타당성을 검증했으며 최종적으로 공공디자인 심미성 향상을 위한 태양전지 적용 방안 디자인 가이드라인을 도출하였다. 향후 태양전지를 활용한 공공시설물의 접근성 및 인지성, 사용성, 형태 및 심미성, 지속가능성 및 에너지효율성, 도시경관과의 연속성 개선을 통한 심미성 향상의 기초자료로 활용되길 기대한다.

and compare the bacterial positive culture rates between patients with subjective symptoms such as eye wax or irritation and patients without symptoms. Methods: Twenty-six anophthalmic socket patients with a prosthetic eye who visited our clinic between December 2009 and May 2011 were retrospectively analyzed. The patients were asked about their symptoms, followed by a conjunctiva examination. Specimens were obtained from the inferior conjunctival cul- de- sac with a sterile cotton-tipped applicator. The collected specimens were cultured. Results: The results indicated that the overall positive culture rate in the anophthalmic conjunctival socket was 69.2%, and the predominant organism was S. epidermidis (38.5%). Potential pathogenic bacteria were found in 4 eyes with a 15% positive culture rate. The incidence of bacteria was significantly higher (85.4%) in patient samples with subjective symptoms compared to patients without symptoms (50%). The bacterial positive culture rate of the potential pathogen bacteria in the group with symptoms was higher at 21%, but was not statistically significant. Conclusions: Performing a pathogen culture test is necessary for prosthetic eye patients who complain of their symptoms. Additionally, the proper antibacterial treatment should be performed according to the antibiotics sensitivity of cultured bacteria.

Purpose: To report a case of fungal keratitis caused by <em>Scedosporium apiospermum</em>. Case summary: A 70-year-old man visited our clinic with complaints of redness and decreased visual acuity in his right eye caused by a soil gotten into an eye while gardening 10 days ago. The patient had previously been treated in a local clinic but did not show significant clinical improvement. Bacterial and fungal staining, culture, and an antibiotic sensitivity test were performed from a corneal scrape. The cultures revealed growth of <em>Scedosporium apiospermum</em>. The patient was treated with topical moxifloxacin antibiotics, fluconazole, amphotericin B antifungal agents. However, the lesion was not improved, so antifungal therapy was switched to topical voriconazole. After two months of treatment, the infection was resolved with mild scarring. Conclusions: Although it is a rare pathogen, <em>Scedosporium apiospermum</em> should be considered as a potential pathogen in patients presenting with corneal ulceration due to trauma from an object contaminated by soil, polluted water, or spoiled plant contact. And we suggest that topical application of voriconazole may be a good alternative treatment for patient with fungal keratitis in which no improvement despite a conventional antifungal agent, fluconazole.

Although several industrial revolutions and technological developments have provided time for modern people, more than 75% of modern people are currently suffering from the problem of "lack of time". Therefore, in this paper, it was judged that it was necessary to improve the mobile APP service for efficient time management of modern people, and a study was conducted on the development of usability evaluation tools. First, the current status was analyzed through case studies of six time management apps with different purposes, and then usability studies were conducted to establish a total of five evaluation principles with operability, cognition, user suitability, minimization of work errors, and sharing. Based on this, a draft of the time management mobile app usability evaluation item was prepared, and a total of 44 usability evaluation tool items were derived through three Delphi surveys of design experts over 5 years and less than 10 years. As a result, intuitive screen and menu composition and user's perception of content were evaluated as the most important factors, and conclusions such as the need to improve the structure and function of the main content screen for user error prevention and usability were drawn. This study will not only contribute to improving the usability of existing time management mobile apps, but will also be used as a material for designing an integrated time management platform for efficient time management and purpose promotion in the future, and is expected to be used as an academic reference. 수차례의 산업혁명과 기술의 발달로 현대인들에게 시간적 여유로움이 생겼지만 이에 반해 현대인들 중 75% 이상이 ‘시간부족 현상’ 문제를 겪고 있다. 이에 본 논문에서는 현대인들의 효율적인 시간 관리를 위한 모바일 앱(APP) 서비스 개선의 여지가 있다고 판단되어 사용성 평가도구 개발 연구를 진행하였다. 먼저 각 목적이 상이한 시간관리 앱 6개의 사례조사를 통해 현황 및 구조를 분석하였으며, 사용편의성에 관한 선행연구를 진행하여 조작성, 인지성, 사용자적합성, 작업오류의 최소화, 공유성으로 총 5가지의 평가원칙을 정립하였다. 이를 기반으로 시간관리 모바일 앱 사용성 평가항목 초안을 작성하였으며, 이것을 5년 이상, 10년 이하의 디자인 전문가 집단을 대상으로 3차례의 델파이조사를 통해 총 44개의 사용성 평가도구 항목을 도출하였다. 그 결과 직관적인 화면 및 메뉴구성과 사용자의 콘텐츠 인지가 가장 중요한 요소로 평가되었으며, 기능적 측면에서의 사용자의 오류 방지 및 사용성을 위한 메인 콘텐츠 화면의 구조, 기능 개선의 필요성 등의 결론이 도출되었다. 본 연구는 기존 시간관리 모바일 앱 사용성 개선에 기여할 뿐만 아니라 향후 효율적인 시간관리 및 목적 증진을 위한 통합적 시간관리 플랫폼 설계 연구의 자료로 활용될 것이며, 나아가 앱 개발 또는 사용성에 관한 학술적 참고자료로 활용될 수 있기를 기대한다.
