공공 데이터 분석을 통한 서울시 전동 공공자전거의 최적의 입지 선정에 대한 연구
전준헌,이우진 한국IT정책경영학회 2021 한국IT정책경영학회 논문지 Vol.13 No.3
In this paper, we proposed the selection of the optimal location for electric shared bicycles, a pilot project of Seoul, by analyzing Seoul’s open data. The Seoul Metroplitan Gaverment started a shared bicycle rental service in October 2015, starting with the pilot operation in 2014, and is preparing for an electric shared bicycle rental service as a pilot project in 2020. As a result of data analysis, it is important to select an initial location. So, in this paper, we analyzed the public data of Seoul and selected the optimal location autonomous region as the criterion that users could use the most. This paper used the jupyter notebook tool for data analysis, and the module was analyzed and visualized using pandas, matplotlib, seaborn, and forlium.

컴퓨터 교과목 교육에서의 플립러닝의 효과적 활용을 위한 연구
전준헌,이우진 한국IT정책경영학회 2023 한국IT정책경영학회 논문지 Vol.15 No.4
In 2020, due to COVID-19, online, non-face-to-face classes at universities were fully implemented. And As mentioned in the regular briefing of the Korea Centers for Disease Control and Prevention on April 11, 2020, ‘The world before Corona will not come back,’ it is believed that changes will be inevitable in university classes. In order to efficiently utilize flipped learning in computer subject education after COVID-19, this paper investigates the perception of flipped learning-based education and suggests efficient utilization plans based on this.

포스트 코로나 이후 블랜디드 러닝 기반 IT 교육에 대한 인식 및 개선 방안 연구
전준헌,이우진 한국IT정책경영학회 2023 한국IT정책경영학회 논문지 Vol.15 No.4
블랜디드 러닝(Blended Learning)에 대하여 학습자마다 정의하는 바가 조금씩 다르기는 하나, 대체로 두 가지의 학습방법을 결합하여 이루어지는 학습을 말하며, 일반적으로 온라인 학습과 오프라인 학습의 혼합된 학습을 가리키는 경우가 대부분이다. 본 논문에서는 블랜디드 러닝이 IT 교육에 미치는 영향을 분석하고자 한다. 이를 위하여 대학생들의 인식 및 만족도를 조사하고 이를 분석하였다.

全俊憲 동국대학교 새마을연구소 1993 새마을硏究 論文集 Vol.10 No.-
This study was carried out with purpose to help efficiency of operation systems in Korea by the comparison of two skidding operation systems(full length system and assortment system), through the study efficiency or performances of skidding systems using the logging bogie with a winch drum. The results of this study are as follows : 1. The average cycle time per turn were 11.3 minute, 11.5 minute, and chocker setting and releasing was the most time consuming elements in operating and choker setting amd releasing time per turn cycle were 29.2%, 59.3% of the cycle time, respectively. 2. The rate of productive hour were 83.79%, 94.82% respectively, and the full length system was 1.4 times much effective than the assortment system as the average skidding volume per 1 cycle were 0.942㎥, 0.672㎥. 3. According to the multiple regression analysis the performace estimated equation could be established Yf=0.36047+0.07974X_1-0.00099X_2+0.00725X_3+0.00320X_4(R^2=0.75580) in case of full length system, Ya = 0.30969+0.04854X_1+0.01142X_2+0.00182X_3-0.02546X_4(R^2=0.57623) in case of assortment system.

무선 센서 네트워크 에서 에너지 효율적인 싱크노드 기반 MAC 프로토콜
전준헌,김성철,Jeon, Jun-Heon,Kim, Seong-Cheol 한국정보통신학회 2014 한국정보통신학회논문지 Vol.18 No.1
In this paper, we propose an energy efficient sink node based MAC protocol for Wireless Sensor Networks (WSNs). The proposed sink node-based MAC (SB-MAC) protocol uses a RB(rapid beacon) frame to save sender's energy consumption and to reduce transmission delay. The RB frame is a modified IEEE 802.15.4 beacon frame. The RB frame contains the length of the sender nodes data. Using this information other nodes except sender and receiver nodes can be stay sleep mode long time to reduce energy consumption. Results have shown that the SB-MAC protocol outperformed other protocols like X-MAC and RI-MAC in terms of packet delivery delay and energy consumption. The SB-MAC protocol is especially energy efficient for the networks with one sink node and many senders.

무선 센서 네트워크에서 센서 노드의 잔여 에너지 기반 Wake-up 제어 메커니즘
전준헌,김성철,Jeon, Jun-Heon,Kim, Seong-Cheol 한국정보통신학회 2017 한국정보통신학회논문지 Vol.21 No.1
In dense deployments of sensor nodes in Wireless Sensor Networks, the MAC protocol has challenges to solve problems such as reducing delivery delay and reducing energy consumption. To solve these problems lots of protocols are suggested. This paper proposed a sensor nodes' residual energy based wake-up control mechanism, in which each node decides whether it wakes up or stays in sleep mode to save energy consumption by reducing unnecessary idle listening. The main idea of the wake-up control mechanism is to save node's energy consumption. The proposed wake-up control mechanism is based on the RI-MAC protocol, which is one of the receiver-initiated MAC protocols. A receiver node in the proposed mechanism periodically wakes up and broadcasts a beacon signal based on the energy status of the node. A receiver node also adjusts wake-up period based on the traffics. Results have shown that the proposed MAC protocol outperformed RI-MAC protocol in the terms of energy consumption.

무선 센서 네트워크에서 군 감시 정찰을 위한 저 지연 데이터 전송 메커니즘
전준헌,이성춘,Jeon, Jun-heon,Lee, Sung-choon 한국정보통신학회 2017 한국정보통신학회논문지 Vol.21 No.4
One of the most important issues in Wireless Sensor Networks is to save energy of the sensor node. But transmission latency is also the problem to solve for some applications such as military surveillance, object tracking. In these applications sensor node needs to send lots of data in limited time when an even such as object appearance occurs. So a delay efficient data transmission method is required. In this paper we propose a MAC protocol adequate for those applications. This paper proposed a low delay data transmission mechanism for military surveillance in wireless sensor networks. In the MAC protocol, a receiver node sends another beacon frame to sender node after receiving data packet. Using this second beacon frame, fast hop-to-hop transmission can be performed. Results have shown that the proposed MAC control mechanism outperformed RI-MAC protocol in the terms of latency.
