The Khronos group releases OpenGL ES 2.0 API specification bringing streamlined shader programming to graphics processor of embedded system. For this reason, the mobile devices have need of graphics processor for supporting a OpenGL ES 2.0 API. We need to extend instruction`s length to support OpenGLES 2.0 API, so it needs more memory size. In this paper, we propose a new instruction format that offers availability for use the instructions. This proposed instruction adopt a variable length method and unit instruction architecture. This proposed instruction architecture that support to OpenGLES 2.0 API has consist of 32bit unit instructions up to 4 which can be combined for embellishing each other. Therefore, it can execute flexible instruction combination and reduce waste of instruction fields.

After the outbreak of COVID-19, local infections were spread by foreign sailors of foreign ships entering the ports. However, the government had difficulties in designating temporary living facilities around port areas due to the opposition from local residents. Therefore, the purpose of this study was to plan a floating temporary living facility for foreign sailors in the port area to prevent the spread of COVID-19 by foreign sailors. In this study, location selection, a facility volumetric plan, a unit facility plan, and a unit facility block plan are presented as results of facility planning. Floating temporary living facilities are expected to be used to prevent the spread of first-class infectious diseases in port areas in the future.

E-sports has grown steadily in recent years and has become a popular sport in the world. In this paper, we propose a win-loss prediction model of League of Legends at the start of the game. In League of Legends, the combination of a champion statistics of the team that is made through each player's selection affects the win-loss of the game. The proposed model is a deep learning model based on Bidirectional LSTM embedding which considers a combination of champion statistics for each team without any domain knowledge. Compared with other prediction models, the highest prediction accuracy of 58.07% was evaluated in the proposed model considering a combination of champion statistics for each team.

생에너지(에너지절약/이용합리화)를 실시하기 위해서는 환경국제규격 ISO14001에 기초한 환경매니지먼트 시스템에 따라 적극적인 추진이 필요하며, ''생에너지의 목표설정(P)'', ''감시 및 측정과 기록(c)'', ''개선(A)''의 P-D-C-A사이클에 대한 지속적인 활동이 중요하다. 전기량의 감시 및 측정과 기록(c)에 대해서도 전기설비 전체를 대상으로 해서는 개선점을 발견하기 힘들며, 보다 세밀한 피더별 관리의 경우가 효과를 거두기 쉽다. 그래서, 분기마다 부하설비별로 전기량을 감시, 측정하고 저코스트로 간단하게 기록할 수 있는 생에너지 지원기기가 필요하다. 그 하나가 ''MDU브레이커''로서 배선용차단기에 계측용 VT''CT와 계측표시유닛MDU(Measuring Display Unit)를 일체화한 제품이다. 대전류가 흐르는 배선용차단기와 서지$\cdot$노이즈를 싫어하는 계측기기인, 언뜻 보아 어울리지 않는 조합이지만 지난 20년 동안의 전자식차단기에 있어서 대전류에 가까운 과전류 검출회로를 정확하게 동작시켜온 경험을 살린 제품이다. 그 MDU브레이커를 사용한 전로감시시스템의 구성예로서 (1)퍼스텀과 시퀀서를 컨트롤러로 하여 MDU 브레이커가 100대 이상인 본격적인 것에서부터 (2)조작표시기로 간단하게 계측할 수 있는, MDU브레이커가 8대 전후인 소규모시스템까지 각종 방법에 대해 소개한다.

An Enterprise Architecture (EA) Framework is a tool which supports implementation of the Enterprise architecture that is used to enhance the interoperability of the IT components. In this paper, we propose a framework named as ENAE (ENterprise Architecture Framework) which combines enterprise architecture unit (AU), reference model, and association relationship between domain model. Architecture Unit is defined as a minimum set of a business process and its associated components such as application system and technical components. An EA can be designed and implemented by the aggregating the related AUs including association relationship between Architecture Units. Because UML model has limitations to describe business domain semantics because it is designed for general purpose, we adapt the DSM (Domain Specific Modeling) concept. We describe association relationship between Architecture Units designed by Domain Specific Modeling through Topic Map. Session 2 describes related works about Enterprise Architecture frameworks, Domain Specific Modeling, and Topic Map, while Session 3 explains components of the ENAF. Finally Session 4 shows the case study for implementation of the new Framework called ENAF.

The recent audio CODEC(Coding/Decoding) algorithms are complex of several coding techniques, and can be divided into DSP tasks, controller tasks and mixed tasks. The traditional DSP processor has been designed for fast processing of DSP tasks only, but not for controller and mixed tasks. This paper presents a new architecture that achieves high throughput on both controller and mixed tasks of such algorithms while maintaining high performance for DSP tasks. The proposed processor, YSP-3, operates four algorithms while maintaining high performance for DSP tasks. The proposed processor, YSP-3, operates functional units (Multiplier, two ALUs, Load/Store Unit) in parallel via 4-issue super-scalar instruction structure. The performance evaluation of YSP-3 has been done through the implementation of the several DSP algorithms and the part of the AC-3 decoding algorithms.

Biochemical oxygen demand (BOD) concentration, one of important water quality indicators, is treated as the measuring item for the ecological chapter in lakes and rivers. This investigation employed novel two-stage hybrid paradigm (i.e., wavelet-based gated recurrent unit, wavelet-based generalized regression neural networks, and wavelet-based random forests) to predict BOD concentration in the Dosan and Hwangji stations, South Korea. These models were assessed with the corresponding independent models (i.e., gated recurrent unit, generalized regression neural networks, and random forests). Diverse water quality and quantity indicators were implemented for developing independent and two-stage hybrid models based on several input combinations (i.e., Divisions 1-5). The addressed models were evaluated using three statistical indices including the root mean square error (RMSE), Nash-Sutcliffe efficiency (NSE), and correlation coefficient (CC). It can be found from results that the two-stage hybrid models cannot always enhance the predictive precision of independent models confidently. Results showed that the DWT-RF5 (RMSE = 0.108 mg/L) model provided more accurate prediction of BOD concentration compared to other optimal models in Dosan station, and the DWT-GRNN4 (RMSE = 0.132 mg/L) model was the best for predicting BOD concentration in Hwangji station, South Korea.

In this paper, we propose a digital transceiver unit design for in-building of 5G optical repeaters that extends the coverage of 5G mobile communication network services and connects to a stable wireless network in a building. The digital transceiver unit for driving the proposed 5G optical repeater is composed of 4 blocks: a signal processing unit, an RF transceiver unit, an optical input/output unit, and a clock generation unit. The signal processing unit plays an important role, such as a combination of a basic operation of the CPRI interface, a 4-channel antenna signal, and response to external control commands. It also transmits and receives high-quality IQ data through the JESD204B interface. CFR and DPD blocks operate to protect the power amplifier. The RF transmitter/receiver converts the RF signal received from the antenna to AD, is transmitted to the signal processing unit through the JESD204B interface, and DA converts the digital signal transmitted from the signal processing unit to the JESD204B interface and transmits the RF signal to the antenna. The optical input/output unit converts an electric signal into an optical signal and transmits it, and converts the optical signal into an electric signal and receives it. The clock generator suppresses jitter of the synchronous clock supplied from the CPRI interface of the optical input/output unit, and supplies a stable synchronous clock to the signal processing unit and the RF transceiver. Before CPRI connection, a local clock is supplied to operate in a CPRI connection ready state. XCZU9CG-2FFVC900I of Xilinx's MPSoC series was used to evaluate the accuracy of the digital transceiver unit for driving the 5G optical repeater proposed in this paper, and Vivado 2018.3 was used as the design tool. The 5G optical repeater digital transceiver unit proposed in this paper converts the 5G RF signal input to the ADC into digital and transmits it to the JIG through CPRI and outputs the downlink data signal received from the JIG through the CPRI to the DAC. And evaluated the performance. The experimental results showed that flatness, Return Loss, Channel Power, ACLR, EVM, Frequency Error, etc. exceeded the target set value.
