A Low-Cost Mechanism Exploiting Narrow-Width Values for Tolerating Hard Faults in ALU

Seokin Hong,Soontae Kim IEEE 2015 IEEE Transactions on Computers Vol. No.

<P>Digital circuits are expected to increasingly suffer from more hard faults due to technology scaling. Especially, a single hard fault in ALU (Arithmetic Logic Unit) might lead to a total failure in processors or significantly reduce their performance. To address these increasingly important problems, we propose a novel cost-efficient fault-tolerant mechanism for the ALU, called LIZARD. LIZARD employs two half-word ALUs, instead of a single full-word ALU, to perform computations with concurrent fault detection. When a fault is detected, the two ALUs are partitioned into four quarter-word ALUs. After diagnosing and isolating a faulty quarter-word ALU, LIZARD continues its operation using the remaining ones, which can detect and isolate another fault. Even though LIZARD uses narrow ALUs for computations, it adds negligible performance overhead through exploiting predictability of the results in the arithmetic computations. We also present the architectural modifications when employing LIZARD for scalar as well as superscalar processors. Through comparative evaluation, we demonstrate that LIZARD outperforms other competitive fault-tolerant mechanisms in terms of area, energy consumption, performance and reliability.</P>

A rare complication: Tension pneumothorax after peroral endoscopic myotomy

Seokin Kang,Yuri Kim,Do Hoon Kim 소화기인터벤션의학회 2022 International journal of gastrointestinal interven Vol.11 No.3

Peroral endoscopic myotomy (POEM) can be safely performed for achalasia. During POEM, gas is insufflated via the endoscope inside the submucosal tunnel. Gas-related complications often cannot be avoided because of the lack of serosa in the esophagus and the inability of the adventitia to function as a resistant barrier to gas. However, tension pneumothorax causing respiratory failure is a rare complication of POEM. Herein, we describe a 32-year-old female who developed tension pneumothorax after POEM. She showed respiratory compromise after POEM, and emergency chest radiography revealed pneumothorax with mediastinal shift. Tension pneumothorax was managed by chest tube drainage with the application of negative-suction pressure via the tube, after which her vital signs stabilized. On post-procedural day 4, the tube was removed. Our case suggests the importance of considering tension pneumothorax if respiratory compromise occurs despite oxygen administration after POEM even in the absence of immediate complications during the procedure, and performing chest radiography promptly.

Elderly Care in Sweden and Japan

Seokin Baek 한국노년학연구회 2000 한국 노년학연구 Vol.9 No.-

In Sweden, the public home help services (PHHSs) have been given to the elderly to live at their homes as long as they do not need a comprehensive supervision and care since 1960. The PHHSs in Sweden led to the change of care paradigm from institutional care to care at elderly's own home, resulting in that the responsibility of caring for the elderly is transferred from the family to the public domain to a great extent. However, the PHHSs in Japan were not well developed until the early 1990s. Many factors, such as collective familiar responsibility on elderly care and shared negative attitudes toward the public welfare services among other things, have contributed to the late development of public welfare services for the elderly in Japan. The practices of the elderly care in both countries are recently questioned in context of structural changes. The PHHSs are now getting harder and harder because of both shrinkage of the family size and increase of women's participation in the labor market in Japan and because of the shrinking economy together with the growing number of oldest old led in Sweden. Consequently, those structural changes forced politicians in both countries to deal with the elderly care problems.

틱톡(TikTok) 이용자의 서비스 태도와 지속이용의도에 영향을 미치는 요인 연구

윤석인(Seokin Youn),송유진(You Jin Song),최세정(Sejung Marina Choi) 한국인터넷전자상거래학회 2021 인터넷전자상거래연구 Vol.21 No.3

With the growing trend of consuming short videos online, this study was intended to identify the factors that influence "TikTok" users’ attitude toward the service and intention to continue using it. Drawn from the expanded technology acceptance model, a research model was constructed in which service perceptions as well as personal and social characteristics were conceptualized to positively influence attitude that in turn leads to stronger intention of continuous use. Reflecting the characteristics of TikTok as a user-generated medium, the continued use intention was gauged as three specific activities: consumption, participation, and production. The results show that perceived usefulness, playfulness, and personalization of the service and social influences have positive effects on attitude. In addition, attitude subsequently exerts positive influences on all of the three use intentions. However, perceived ease of use and personal innovativeness did not appear to have significant effects. The findings provide theoretical implications on the antecedents of attitude and continued use intention as well as strategic insights into short-form video services.

연구장비산업의 비즈니스 생태계 모형 개발 및 사례 분석

정석인(Seokin Joung),정의덕(Euhduck Jeong) 한국기술혁신학회 2020 기술혁신학회지 Vol.23 No.2

우리나라는 해외 선진국들의 과학기술을 모방하고, 학습하는 추격형 R&D 전략을 통해 지난 50년간 산업발전과 경제성장을 이끌어왔다. 그러나 추격형 R&D는 국내 연구·산업의 주요수단인 소재, 부품, 장비의 대외의존도를 제고시켰고, 이는 오늘날 세계시장경쟁의 한계로 나타나기 시작하였다. 이제는 과거방식을 탈피하고, 주도형 R&D로의 전환이 필요할 때이며, 이를 위해선 먼저 R&D수행 시 연구장비의 외산구매를 자제하고, 자체 연구장비의 개발·생산을 촉진하는 국내 연구장비 진흥정책의 변화가 요구된다. 따라서, 본 연구는 이러한 정책변화의 기본 틀을 제공하기 위한 노력으로 국내 연구장비산업 내에 구성된 산·학·연·관 이해관계자, 역할과 기능, 그리고 주체간의 상호작용들을 쉽게 설명할 수 있는 연구장비산업의 비즈니스 생태계 모형을 개발하고, 실제 개방형 R&D와 관련된 몇 가지 공진화사례들을 분석하여 과학기술과 장비개발산업의 정책적 시사점을 제시하고자 한다. 특히, 본 연구는 생태계 모형 개발을 위해 Moore(1993)의 비즈니스 생태계 이론을 적용하였고, 모형검증을 위해 정부출연(연)과 장비제조사의 기술이전 및 사업화 사례를 조사하였다. Korea has led industrial development and economic growth for the past 50 years through a chasing R&D strategy that mimics and learns the science and technology of overseas advanced countries. However, the chasing R&D strategy has increased the external dependence of materials, parts and equipment, which are the main means of domestic research and industry. This began to appear as a limitation of today"s global market competition. Now is the time to move away from the past and to switch to a leading R&D strategy. To this end, it is necessary to change domestic research equipment promotion policies to refrain from purchasing foreign products and promote the development and production of own research equipment in the future. Therefore, this study is an effort to provide a basic framework for such a policy change. In the study, we developed the business ecosystem model of the research equipment industry to easily explain stakeholders of industry/academia/research, the interactions among them, and roles & functions. Moreover, we tried to present policy implications of science technology and equipment development industry by analyzing actual open R&D and related coevolution cases. In particular, this study applies Moore(1993)"s business ecosystem theory to develop the ecosystem model, and examines the cases of technology transfer & commercialization of government-contributed research institutes and equipment manufacturers for the model verification.
