Recently, interest in the environment and well-being is increasing due to changes in people's level of consciousness. Accordingly, it is trying to reduce disposable products, and interest in "water diet" is increasing as a way to maintain a healthy body. Many people use portable tumblers to drink water or drinks, and in particular, recently, they have evolved into a smarter form that provides various functions to increase user convenience. Existing studies have limited drinks to "water," so there is a limit to monitoring various drinks. To solve this problem, this paper produced a smart tumbler that can judge drinks using IoT technology and monitor the intake of drinks. In addition, it became possible to measure the intake more accurately by judging the case of throwing away the beverage without drinking it. Based on the data of various IoT-based sensors, the user can identify the intake amount of each drink in a dedicated application and receive various conveniences.

Most of the disaster relief items provided to sufferers and temporary evacuees that are supposed to be victims in Korea are not suitable for the shelter environment of temporary housing facilities, and are not satisfactory because they do not have the functions, proper size and types. The purpose of this study is to analyze the user needs of emergency rescue relief items by presenting problems about the use environment and to develop the variable air mattresses which are based on disaster prevention design. In order to secure objectivity such as usability, convenience, and durability, research data are limited. However, the difficulty of mass spreading of conventional fiber mat and the functional disadvantages of foam plastic mat are solved by adopting variable air mattresses. The variable air mattresses are expected to help rehabilitate people by helping victims of physical tiredness, illness worsening, poor sleep, and life instability that can happen during long-term shelter life.

When oral restoration is performed with a full mouth implant-supported fixed restoration in an edentulous patient, it is very important to determine the shape and position of the definitive prosthesis in consideration of the anatomical state and the relationship with the antagonist, and the process of placing multiple implants in the planned direction and angle is very important. In this case, implants were ideally planned based on an upper prosthesis through a computer-guided surgical procedure for an edentulous maxillary patient who visited due to discomfort in the existing denture. Through this, we would like to report this because we obtained satisfactory functional and esthetic results for both the patient and the operator with the treatment of oral restoration by manufacturing a fixed prosthesis for maxillary and full jaw implants.

This study was conducted to examine the effect of organizational safety culture on radiologists' awareness of patient safety and safety behavior. The study was conducted based on the results of the survey, and the survey was divided into three factors: general characteristics, efforts for patient safety, and patient safety culture. As a result of the study, age, work experience, and work satisfaction were influencing factors in general characteristics, and gender, academic background, and work type were not included as factors affecting differences in patient safety awareness. In efforts for patient safety, hospital support and education, patient safety activities, and how to respond to errors were all influencing factors, especially how to respond to errors were more relevant than other items. The patient safety culture was analyzed on two items: teamwork and open communication, and both items were highly related to radiologists' awareness of patient safety.

Over-the-counter pharmaceuticals sold in convenience stores are accurate and easy to understand on its containers, packaging, or attached materials for the prevention of drug misuse. The limited space of the packaging, however, makes the information difficult to read and consequently, consumers have had difficulty in purchasing the products. This research conducted an analysis of 8 packages of pill-type drugs and conducted a survey and interviews targeting 10 foreigners and 20 Korean consumers to analyze the user consciousness. The findings of this study showed that fever remedies are the most frequently bought drug. And consumers first looked for the information of the drugs in the following order: the effects, dosage, and warnings. While domestic consumers had little difficulty in comprehending the information, more than 40% of the foreigners who were studies failed to comprehend it, which was because the package was entirely written in Korean. This study presented some ideas for improving the design by using English and foreign expressions and pictograms, consumers can easily and quickly understand, and by placing the information on the symptoms, dosage and age information so that the type of drugs will be easily discernible.

기후변화로 인하여 발생하는 자연재해는 수많은 인명 및 재산 피해를 일으키며, 그 중에서도 가뭄은 물과 식량의 안보를 위협하고 있다. 이에 OECD(2015)는 미래의 세계 인구 40%가 2050년까지 물이 부족한 강 유역에서 살 것이라 예측하고 있으며, 물의 다층적 거버넌스를 개발하여 물을 효과적으로 사용하기 위한 상향식 의사결정, 통합물관리 체제의 개념을 제시하기도 하였다. 우리나라 역시 가뭄으로 인한 피해발생이 빈번하고, 그 강도나 범위가 점차 증가하는 추세이다. 하지만 2000년부터 한국농어촌공사(출범은 '농업기반공사')가 농업용수를 관리해오고 있으며, 농업용 수리시설의 증축, 관리 등이 공적인 관리쳬계로 변화해오면서 자연스럽게 농업인의 물관리는 배제되었다. 또한, 농업용수는 무상·무제한 공공재라는 인식과 농업인 평균 연령이 높아짐에 따라 농업인의 물꼬관리 및 수로 훼손, 무단취수 행위 등에 대한 제제가 불가능한 실정이다. 본 연구에서 최근 농식품부의 「2019년 정부가뭄종합대책」에 포함되어 있는 물절약 거버넌스 구축 및 운영 내용을 바탕으로 농업용수 관리 및 사용구조를 고려하여 두 개 지역의 농어촌공사(여주이천지사, 경주지사) 주도 하에 거버넌스를 간담회 형식으로 운영하였다. 농업용수 물절약 거번넌스 이해관계자들은 각 지역별 공기업, 공무원, 농업인, 언론인, 학계 전문가 등이 참가하였으며, 거버넌스 운영 2회 및 설문조사를 실시하였다. 그 결과 각 이해관계자들은 농업용수 절약을 위한 현재 문제점 및 해결방안 등에 대한 의견을 제시하였으며, 설문조사를 통하여 농어촌공사의 신뢰도 및 중요도가 가장 높고, 높은 중요도에 비하여 농업인 및 지자체 등은 신뢰도가 낮은 것을 확인 할 수 있었다. 이러한 결과는 농업인이 농업용수에 대한 주인의식을 가지고, 적극적이고 자발적인 참여가 필요하다는 것을 보여주고 있으며, 본 연구를 통하여 이루어진 간담회 형식의 거버넌스보다 운영효과 및 지속성을 유지할 수 있는 형태의 거버넌스가 연구되어야한다. 향후 농촌형물 거버넌스 모형이 개발되기 위하여 본 연구는 기초자료로 활용할 수 있다.

High-altitude cerebral edema (HACE) is a potentially fatal neurological syndrome that develops in persons traveling to a high altitude. We report the case of a 49-year-old male who had traveled to a high altitude, and lost consciousness for a few hours. Susceptibility-weighted images revealed multiple, fine black pepper like microbleeds along the corpus callosum with several microbleeds in the left frontal and parietal subcortical white matter. The T2-weighted images did not show any abnormal signal intensities along the corpus callosum. The diffusion-weighted images revealed small nodular high signal intensities in the basal ganglia. This report describes the atypical radiologic findings of HACE showing multiple microbleeds along the corpus callosum, without abnormal high-signal intensity on T2-weighted images.

As the number of security incidents and damages increase steadily, interest in the security of society is growing, and the amount of academic interest and research is steadily increasing. However, despite these concerns and the quantitative increase in research, the terms 'security' and 'safety' have been mixed and studies have been conducted without the conceptual definition of various security terms being clearly defined. As a result, various forms of security concepts based on ICT environments have been misused. Therefore, we tried to derive the consensus of experts among the various security terms which are mixed in this study, and to summarize the concepts based on the analysis of domestic and foreign documents based on the concept of the terms. Through this research, we intend to contribute to the establishment of the academic identity of security by preventing related mistakes caused by the mixed use of terminology.

The original purpose of SNS was to facilitate online networking among people. However, in recent years, this purpose has been faded, and the platform has become more of a means of self-promotion than genuine self-expression. This paper proposes and implements POCHAK, a social media platform designed to address the aforementioned issues and facilitate "sound communication." The POCHAK platform does not permit the users to take their own photos, thereby eliminating the potential for photos being manipulated and retouched. The POCHAK platform only allows other people to take photos of users only through the in-app camera. Furthermore, the photos cannot be edited during the upload process and cannot be saved before uploading, thus requiring users to upload the photos in their original form. In this paper, we implemented the POCHAK platform as an iOS app, application server, data management server, and photo storage server, and verified its feasibility by utilizing it in the field. We are sure that the POCHAK platform will be a new type of SNS platform that regains the original purpose of SNS and enables sound communication.
