We demonstrate, for the first time, 28-nm embedded STT-MRAM operating at full industrial temperature range (−40~125°C) with >1E+6 endurance and >10 year retention for high speed MCU/IoT application. Robust cell operation is also demonstrated after solder reflow (260°C, 90 second) and during external magnetic disturbance (550-Oe under writing). It is built on 28-nm FDSOI technology in modular format for IP reuse and has great potential to serve wide variety of applications such as IoT, and high p

The enormous increase in heterogeneous wireless devices operating in real-time applications for Internet of Things (IoT) applications presents new challenges, including heterogeneity, reliability, and scalability. To address these issues effectively, a novel architecture has been introduced, combining Software-Defined Wireless Sensor Networks (SDWSN) with the IoT, known as the SDWSN-IoT. However, wireless IoT devices deployed in such systems face limitations in the energy supply, unpredicted net

This study explores differing landscape perceptions of Bukhansan National Park according to the degree of visitors’ familiarity, and discusses the utilization of commonality and diversity of landscape perception in sustainable landscape management. Visitor-employed photography (VEP) was used to capture the overall response to experiencing landscape directly on-site. According to the degree of familiarity of national parks, visitors were recruited into two groups: inexperienced group (the novice

Trajectory prediction is critical for ensuring the safety, reliability, and scalability of Unmanned Aerial Vehicle (UAV) in urban environments. Despite advances in deep learning, existing methods often struggle with dynamic UAV conditions, such as rapid directional changes and limited forecasting horizons, while lacking comprehensive real-time validation and generalization capabilities. This study addresses these challenges by proposing a gated recurrent unit (GRU)-based deep learning framework

We developed a 4Mb split-gate e-flash on 28-nm low-power HKMG logic process, which demonstrates the smallest bit-cell size (0.03×-um <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) for high performance IoT applications. High speed operation (25us write time and 2ms erase operation) and robust reliability (500K cycle, 10 years retention) are achieved through optimization of triple-gate flash architecture and scaling of word-line (WL) transi

We present a document model which integrates the logical structure and hypertext link structure of hyperdocuments in order to manage structured documents with hypertext links. Based on this model we define a new structure query language which expresses the structure query using path expressions. To process a structure query in a document management system which represents structure information as database relations, costly join operations are used to find a relationship between elements in a doc

The purpose of this study is to understand the architectural changes according to the introduction of the Korean modern system of weights and measures during the modernization period, through the investigation of the developing process of this system. The first Korean system(「度量衡規則(1902」) had its own contents that adjusted the Korean traditional units of distance and area to the international metric system of measurement, even though it imitated the form of the Japanese system(「度量衡取 締條例(1875)」).

옥수수 섬유질을 이용한 고식이섬유 식빵을 제조하기 위하여 옥수수 섬유질을 수분함량 30, 40%, 배럴온도 140°C, 스크루 회전속도 200 rpm으로 압출성형 처리한 후 첨가율에 따른 제빵특성을 검토하였다. 식빵의 부피는 옥수수 섬유질의 첨가비율이 증가함에 따라 감소하는 경향을 보였다.BR압출성형 옥수수 섬유질 5% 첨가군에서는 수분함량 30, 40% 압출성형 옥수수 섬유질 첨가 식빵의 비체적이 각각 5.688, 5.712로 대조군 5.222(L/kg)보다 더 높게 측정되었다. 저장 기간 동안 옥수수 섬유질 첨가 식빵의 경도는 대조군과 압출성형 옥수수 섬유질첨가 식빵보다 높은 경도 값을 나타내었다. 그러나 옥수수 섬유질과 압출성형 옥수수 섬유질 5% 첨가 시 저장기간에 따라 대조군보다 낮은 결과를 보여주었다. 관능검사 결과는 대체적으로 첨가비율이 증가할수록 선호도가 떨어졌다. 이는 첨가물의 비율이 높을수록 품질특성이 낮아지는 결과와 일치한다. 옥수수 섬유질을 압출성형하여 첨가하였

ABSTRACT Three studies showed that the way that options are presented in a choice set—as combinations of intersecting attributes or in a more sequential “a la carte” choice format—affects the degree to which consumers adhere to their goals in the consumption setting. Specifically, using the context of food consumption and healthy eating, results showed that consumers were more likely to make double indulgent choices, the choice of both an indulgent entrée and an indulgent side item, when choosin

The policy of foreign conquest during the late Koryo started in earnest at the beginning period of King Gongmin. The keynote of policy which had planned and tried the foreign conquest, had great effect on the late Koryo & the early foundation of Chosun Dynasty. The policies of King Gongmin who pursued his own country's area & expanding foreign influence through foreign conquest, went on after the foundation of Chosun Dynasty as well as the era when Yi Seong-gye & the rising group of nobility wer

Recently, LINUX cluster file systems using the storage area network (SAN) have been developed. The Global File System (GFS) implemented at the University of Minnesota is such an example. These systems do not use a central file server, and instead, multiple clients sharing the whole disk storage through Fibre Channel can freely access disk storage and act as file servers. Accordingly, they offer advantages such as availability, load balancing, and scalability.
