Jieun Lim,Soowan Kim,Hong Geun Kim,Doo-Hyung Lee 한국응용곤충학회 2017 한국응용곤충학회 학술대회논문집 Vol.2017 No.04

The bean bug, Riptortus pedestris, is a pest of leguminous crops. Recent studies have revealed an interesting relationship between R. pedestris and a gut symbiont Burkholderia sp.. R. pedestris mainly acquires Burkholderia sp. during 2nd instar period, which leads to enhancement of growth and reproductive rate of the host. Nevertheless, how R. pedestris acquires its symbiont is not yet clearly described. Therefore, we investigated whether 2nd instar nymphs have preference on Burkholderia sp. compared to untreated control in laboratory settings. In the choice test, no significant difference was found in the preference by R. pedestris between the two treatments. To further investigate single individual’s behaviors (its first choice, approaching frequency to each treatment, and residence time on the treatment). We video-recorded single individuals in the choice setting for 12 hours. Again, there was no significant difference in any of the behavioral traits recorded. Further choice tests will be conducted in the Y-tube olfactometer systems and semi-field conditions.

A Hard Decision LDPC Decoder Implementation for Error Correction of NAND Flash Memory

Jieun Lim,Junho Cho,Wonyong Sung 대한전자공학회 2008 ICEIC:International Conference on Electronics, Inf Vol.1 No.1

We implemented a decoder for low-density paritycheck (LDPC) codes intended for NAND flash memory error correction. Since the input is given as a binary valued signal, a hard-decision bit flipping based decoding algorithm is used. To simplify the hardware, a circular shiftregister based partially parallel decoding architecture is employed. With this architecture, it is very easy to increase the throughput or reduce the power consumption by raising the parallel factor. The implemented decoder, which employs a (4161, 3431) projective geometry-based LDPC code, operates at 400 Mbit/s throughput with the parallel factor of 32. Synthesized using a 0.25㎛ CMOS technology, the proposed decoder consumed 208 ㎽ with 2.5 V supply.

The purpose of this research is to explore what challenges instructors in higher education faced in online instruction and what strategies they suggested as important to improve online courses. We also explored how instructors’ attitudes toward online courses were shaped by the online teaching experiences. For the data collection, we conducted in-depth interviews with eight instructors in higher education and all interview data were analyzed using a constant comparison method. The result of this study showed that most instructors were not fully ready for online teaching. In particular, they faced a variety of challenges including the lack of immediate interaction and nonverbal communication, low instructor presence and teaching motivation, redesigning the collaborative and hands-on learning activities, and conducting reliable and valid online assessments. In order to cope with the challenges, the instructors put much emphasis on the active and practical efforts and intervention for online interaction, specific and systematic organization and announcement for course structure, providing activities for promoting learner engagement and application, sharing course materials relevantly and avoiding instructor misbehaviors in online courses. Finally, this research confirmed that the instructors believe that online teaching will be inevitable, even post Covid 19. In the study, we also identified that these online teaching experiences made the instructors more interested in blended learning for their future courses. Covid 19 is not only a great challenge for the traditional education system but also an important turning point to move to new ways of teaching and learning in an online learning environment. More systematic efforts and supports will be necessary to promote high-quality online learning and help instructors improve their online teaching competencies.
