Methylene blue is a basic thiazine dye frequently used for histologic staining. In clinical toxicology settings, it is also used to treat clinically significant methemoglobinemia. It has dose-dependent oxidation or reduction properties, acting as a reducing agent at lower doses and as an oxidizing agent at higher doses. Hemolytic anemia and hyperbilirubinemia are known toxic effects of methylene blue treatment that have been reported clinically. A 42-year-old woman developed significant methemoglobinemia after acute dapsone overdose; she was treated appropriately with intravenous methylene blue in the therapeutic range. The patient's methemoglobin levels returned to normal. However, 2-4 days later she was noted to have rebound methemoglobinemia, hemolytic anemia, and hyperbilirubinemia. A repeat of Coomb's test and other anemia workups were negative. For management of methylene blue-induced hemolytic anemia, she was administered steroid therapy, N-acetylcysteine, and a blood transfusion. She ultimately recovered, and there were no long-term sequelae from the methylene blue poisoning.

본 연구는 일상에서 길을 찾는 데 어려움을 겪은 보행자나 초행길을 낯선 여행자들을 대상으로, 스마트폰과 더불어 사람들이 많이 지니고 다니는 가방을 가지고 적용하였다. 스마트폰의 LBS, 블루투스 기능과 가방에 부착된 진동 인터페이스가 연결되어 실시간 경로 안내를 받을 수 있는 제품이다. 부가적인 기능으로는 앱 상에 회원관리 기능이 있어 개인의 이용 기록에 관한 데이터가 DB에 저장되며 DBMS를 통한 데이터 분석으로 사용자에게 맞춤화된 서비스를 제공해 줄 수 있다. 또한 여러 사용자들이 이용한 플랫폼에 쌓인 데이터를 가지고 새로운 비지니스를 창출할 수도 있다. 추가적으로 일정 거리 이상 멀어지면 신호의 강도가 약해지는 블루투스의 특성을 이용하여 이용자가 가방과 일정 거리 이상 떨어질 경우, 스마트폰으로 팝업 창을 띄워주는 형태로 분실 방지 기능을 제공해 줄 수도 있다.

Various methods are being presented to identify the movements of COVID-19 infected persons and to protect personal privacy at the same time. Among them, 'Exposure Notification' released by Apple and Google follows a decentralized approach using Bluetooth. However, the technology must always turn on Bluetooth for use, which can create a variety of security threats. Thus, in this paper, the security assessment of 'Exposure Notification' was performed by applying 'STRIDE' and 'LINDDUN' among the security threat modeling techniques to derive all possible threats. It also presented a new Dell that derived response measures with security assessment results and improved security based on them.

Recently, in order to increase the efficiency of the product production process, the automation of facilities and devices in the factory is in progress, and a smart factory is being built using ICT and IoT technologies. In order to organically solve many problems occurring in the smart factory, a system for monitoring the wireless communication function between facilities and devices and the manufacturing process environment of the smart factory is required. In this paper, we propose a monitoring system using a Bluetooth module, a temperature/humidity sensor and a fine dust sensor to remotely monitor the process environment of a smart factory. The proposed monitoring system collect Arduino sensor values wirelessly through Bluetooth communication.

In order to collect a lot of data clearly and efficiently, it is essential to know the locations of the current facilities and analyze the movement data. The current location collection technology can collect data using a GPS (Global Positioning System) sensor, but in the case of GPS, it has strong straightness and low diffraction and reflectivity, making it difficult to position indoors. It is impossible to measure the distance between the server and the client because the signal sensitivity cannot be received. This paper implements an indoor positioning system using beacons and scanners in Raspberry Pi 3 B+. It controls Advertise Mode and Connection Mode at the same time using the scanner algorithm.

Recently, starting with the permanent suspension of Gori 1 in Korea, the importance of the disposal of concrete structures in nuclear power plants has emerged, and environmental and safety are required to be proved accordingly. Safe radioactive waste disposal technology that immobilizes harmful radioactive elements, which are by-products of nuclear power, inside a solid matrix and recycling measures are needed to secure an efficient waste disposal space. This study was conducted to confirm whether recycled cement generated in the process of radioactive concrete treatment can be used as a solidifying material for radioactive waste treatment. In order to simulate the concrete exposed to radiation, aqueous solutions of Di-water, CsCl 1M, and CoCl₂ 1M were used as blending water at W/B 0.5. Tricalcium phosphate and Prussian blue were substituted with 5 wt.% based on the weight of recycled cement as a binder to improve solidification performance, and their hydration characteristic was analyzed.

The Mongolian lingonberry and blueberry are two essential food sources found in Mongolia. This study investigated the antioxidant and anti-inflammatory effects of methanol extracts from Mongolian lingonberry (LBE) and blueberry (BBE). Compared to the LBE, the BBE showed higher total phenolic, flavonoid, and anthocyanin contents, as well as antioxidant capacities. The LBE and BBE inhibited the mRNA expression of pro-inflammatory genes, including tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and cyclooxygenase (COX-2) in lipopolysaccharide-stimulated RAW 264.7 macrophage cells. In addition, the LBE and BBE inhibited NADPH oxidase-2 (Nox2) mRNA expression, indicating that they have cellular antioxidant capacities. Anthocyanin derivatives of the LBE and BBE were analyzed using LC-QTOF/MS. Six anthocyanins were identified in the BBE, while one was detected in the LBE. Our findings demonstrate that the anthocyanin-rich LBE and BBE could be used as functional food sources in Mongolia.

This study was performed about color-contained mud to provide fun and diversity for the event of mud self massage as a core program of Boryeong Mud Festival which has become one of representative festivals in Korea. Adjusting its own lower brightness of mud and based on the primary study performed about the expressivity of yellowish colors, inorganic colors (oxidized steel in red, ultra marine pink, ultra marine blue, chrome oxide green) were added for the development of colored mud in diverse colors on the basis of Korean traditional colors. It had been judged about each expressivity of color by methods of colormeter, naked eyes inspection and feeling of usage, etc. For the color decided, it had been examined about the coloring when it got wet with the cleaning condition so that it can be used for the event of mud self massage as a program of Boryeong Mud Festival to increase diversity of the Festival and also attempted to develope colored mud to show Korean traditional colors.

Currently, mobile handset embeds many communication modules including CDMA and Bluetooth, and many applications are developed based on these modules. In this paper, we study about wireless vehicle diagnosis software and user interface based on bluetooth system on mobile handset. We developed Bluetooth communication system on protocol converter between OBD(On Board Diagnostics)-II system. Based on this system, we can communicate ECU(Engine Control Unit) and mobile device based on windows .NET compact framework platform. Therefore we can easily diagnose vehicle state and obtain engine data. All user interface and vehicle diagnosis systems on mobile handset are developed under windows .NET compact framework platform. Using this system we achieved several improvements over existing vehicle diagnostic system; 1) the software download and upgrade can be achieve on wireless environment, 2) no additional diagnostic devices are requires, which saves additional cost and we can diagnose the vehicle easily, 3) we can easily port our system on many embedded systems including PDA and navigator, etc.
