The purpose of this paper is to study the direction of improving kiosk design for convenient use by all users by increasing the usability of kiosks based on universal design principles. The direction of design improvement was studied by deriving essential improvements through additional surveys verifying the results of age-specific surveys and analysis related to the use of kiosks. The results of the study are as follows. High contrast between kiosk screen background and design elements, yellow color, and outline design elements increase readability. Then, reduce and enlarge the font based on 10pt. In addition, in consideration of wheelchair passengers, the area where the lower part cannot be designed and the minimum height of adjusting the height of the kiosk were derived. In the future, kiosk design requires a design and system that can diversify the functions of kiosks according to individual characteristics, and design should be focused on the application of universal design. Since this study has limited research subjects, further studies on various samples are required, and verification studies related to color and readability will also be conducted.

Purpose: Currently, port facility informatization technology is focused on the planning and design phases, so the necessity of research and technology development on the port facility maintenance system based on life cycle-level information is emphasized. Method: Based on the maintenance history data of port facilities and facility operation information, from the perspective of the life cycle of port facilities, the system is configured to enable maintenance decisions for port facilities through analysis of aging patterns, performance degradation prediction models, and risk analysis and proposed a method of expressing information. Result: A function was developed to simultaneously display the SOC performance evaluation and the comprehensive performance evaluation developed in this study, so that mid-to long-term maintenance and reinforcement and facility expansion can be applied and comparatively judged. Conclusion: The integrated port performance system developed in this study induces and supports the risk minimization of port facility management by proactively promoting appropriate repair and reinforcement measures through historical and operational information on port facilities.

Due to the recent increase in the disabled population and welfare paradigm, the government is focusing on green welfare and environmental welfare to improve the living environment of the disabled, including the enactment of basic laws and convenience promotion laws. Accordingly, green environmental welfare for the disabled is supported in policy, but there are no evaluation indicators for the green welfare space and healing environment created. Therefore, this study divided the healing environment into physical, psychological, and social aspects, and conducted research using expert FGI to present evaluation indicators that can determine whether spatial roles and functions are appropriate. As a result of the study, the final 51 healing environment evaluation items were derived from 26 physical aspects evaluation items, 14 psychological aspects evaluation items, and 11 social aspects evaluation items. Evaluation indicators derived from this study can be used to evaluate the healing environment created in disabled residential facilities, and can be used as basic data in the planning stage of the healing environment to be created in the future.

Interest in peanuts driven by their various biological activities and abundant nutrition engenders research interest in peanut sprouts for determining their biological activities and nutrition. Several research groups have recently studied the peanut sprout ingredients, but these studies focused on the peanut sprout extracted by methanol, an inedible extraction solvent. Thus, the present study provides the contents of two biologically active compounds, resveratrol and aspartic acid, in peanut and peanut sprout extracted by hot water and fermented ethanol, two edible extraction solvents, using UPLC-MS/MS technique. The UPLC-MS/MS results show that the peanut sprout extracted by fermented ethanol has the highest resveratrol and aspartic acid contents. This extract also exhibited the highest inhibitory effect on adipocyte differentiation, which the resveratrol may induce. Consequently, peanut sprout extracted by fermented ethanol might be helpful for the development of functional food plant materials.

Recently, services using metaverse in various fields are increasing, the technology is behind the metaverse is rapidly developing. Consequently, it is necessary to provide metaverse services in university libraries. Therefore, this study examined the status of using metaverse in domestic university libraries and the librarians response to it. To this end, the cases of foreign libraries and domestic university libraries were analyzed. Furthermore, an interview was conducted with nine librarians of the university library, who has running metaverse service, to collect data on the current status of the university library metaverse and perceptions of it to identify difficulties and requirements of running the service. Based on the results, it is proposing to get the differentiation of metaverse service, acquire professionals, activate education, expand the browsing feature, and select proper platforms as a way to vitalize the metaverse of domestic university libraries. It is expected that this study will help to running or planning the metaverse service of the university library.

In the current business environment where dependence on IT has increased rapidly, the risk from disasters or cyber-attacks is also increasing. Business continuity, the ability to continue to provide service in the event of a business disruption caused by a disaster, is essential. In other words, you need to have a plan in place to keep your core business functions uninterrupted with rapid recovery within a predetermined Recovery Time Objective (RTO) and Recovery Point Objective (RPO) time frame. In this paper, we propose a disaster recovery system construction method that can minimize RTO and RPO to ensure business continuity. The system configuration adopts Tier 7 disaster recovery model, synchronous storage replication, hot disaster recovery site, and operation management automation solution. This ensures continuity of core business with virtually no data loss and minimal RTO and RPO.

The development of digital technology is causing great changes in dentistry. This digital workflow combines various 3D data in the prosthetic treatment area for diagnosis and prosthetic manufacturing. The planned diagnosis and the fabrication of prosthesis in a virtual patient formed by synthesizing digital data can simulate the results of prosthetic treatment more intuitively than conventional methods, thereby increasing the predictability of aesthetic prosthetic treatment. In this case report, functionally and aesthetically satisfied clinical results were obtained by fabricating a fixed partial dentures through a digital workflow on congenital missing teeth in the maxillary anterior region.

일반적으로 수자원가용량이라 하면 지표·지하·토양 등에 있는 모든 수자원의 양이라 할 수 있다. 정확한 수자원가용량의 평가를 위해서는 강수, 기온 등의 기상 예측의 정확도 확보가 우선되어야 하며, 지표 하에 보이지 않는 수자원의 양을 정확히 평가할 수 있어야 한다. 한국건설기술연구원은 2012년부터 세계기상기구(WMO, World Meteorological Organization)에서 수자원평가 부문 리더 역할을 수행하면서 회원국들에게 수자원가용량평가를 위한 '동적수자원평가시스템'의 개발을 제안하여 추진하였다. 그 결과, 동적수자원평가시스템(Dynamic Water resources Assessment Tool, DWAT)이 2017년 12월에 개발되었고, 2019년 5월에는 WMO 웹사이트 (https://public.wmo.int/en/water/dynamic-water-resources-assessment-tool)를 통해 193개 회원국에 보급되기 시작하였다. DWAT은 전 세계가 무료로 이용할 수 있는 수자원평가 도구로, 지하수, 용수이용 뿐만 아니라 지표수를 고려한 수자원계획 및 관리를 위해 중⋅소규모 하천 유역에 적용될 수 있다. 특히, 논 지역의 유출특성을 모의할 수 있는 모듈을 탑재하였으며, 고위도 및 고산지대의 수문학적 특성을 반영할 수 있는 융설 모듈이 포함되었고, 매개변수 최적화 기능도 포함되었다. WMO는 수자원분야 주요사업 중 하나인 "전지구 수문현황 및 전망 시스템(HYDROSOS, global HYDROlogical Status and Outlook System)" 사업을 추진하고 있다. 본 사업은 전지구 기상예보를 활용하여 주요 지점의 자연 유출량에 대한 현황과 예보를 수행하는 것을 목표로 한다. 2019년 6월 제18차 WMO 총회에서는 수자원분야 주요 사업인 HYDROSOS의 시범사업을 DWAT이 지원하는 것으로 의결되었다. 따라서 이러한 DWAT의 활용을 통해 대한민국의 수자원 평가 실무와 관련된 기술이 WMO 회원국에 지속적으로 보급될 것으로 판단된다.

In this paper, we develop a construction business information portal system. Our portal system consists of two major parts including a institution portal and a public portal. The institution portal is for the people working at governmental agencies and the public one is for general users. This paper adopted Method/1 as the development methodology of the portal system and made the portal using Java-based web application framework. After the development of the portal. we tested it step by step to improve its quality and run Help-desk for the stable operation and maintenance. In the future, we will develop some additional contents required by users.
