The objective of this study is to develop a condition assessment model based on artificial neural network that can be used to analyze the mechanical flexural design behavior of slab bridge with damages and the flexural design program behavior of damaged slab bridge. A modified rating factors that can be applied to flexural design method algorithm is used to reflect the external condition assessment, the required strengthening moment computed from the rating factors is considered as additional moment term acting on slab and represent the effect of external condition. The accuracy of the proposed algorithm is verified by comparing the analysis results with the field measurement data from other studies and the analysis results based on ultimate strength theory. The debeloped damage model is applied to the analysis of slab bridge with damage under nonlinear elastic condition. The comparisons confirmed that the quantitative analysis of required strengthening thickness of the fiber-reinforced epoxy panel(FREP) due to optimum neutral position.

선주원 ( Seon¸ Ju-won ),유정희 ( Yu¸ Jeong-hee ) 한국초등국어교육학회 2021 한국초등국어교육 Vol.71 No.-

이 글은 초등 서사교육에서 교육내용으로 작용하고 있는 학습활동들이 서사적 지식의 학습을 위해 정렬성 있게 설정되어 있는가를 분석하고, 그에 대한 대안활동과 지도방안을 제시하였다. 이를 위해 서사적 지식 관점에서 문학 영역의 성취기준 및 학습활동을 [5-6학년군]을 중심으로 분석하고, 서사적 지식의 균형적 학습을 위한 학습활동을 새롭게 구안하였다. 그런 다음 새롭게 구안된 학습활동의 지도를 위한 방안을 제시하였다. 이 글의 논의는 서사교육의 맥락과 실제, 서사교육의 지향점과 교육내용, 실제적 활동의 수행, 실제적 활동에서의 태도나 윤리, 맥락 등이 서사교육에서 학습활동으로 구현되어야 함을 강조하는 방향에서 이루어졌다. 아울러 서사교육에서의 학습활동이 교과서에 제시된 학습활동, 즉 기본학습 및 실천학습과 분리될 수 없음을 강조하는 차원에서 이루어졌다. 이를 통해 이 연구는 학교 현장의 서사교육의 지향을 새롭게 마련할 수 있었다. This article analyzes whether the learning activities that act as educational content in elementary narrative education are reasonably established for the learning of narrative knowledge, and suggests alternative activities and guidance measures. To this end, achievement standards and learning activities in the literary domain were analyzed from an epic knowledge perspective, and learning activities were newly devised for balanced learning of narrative knowledge. It then presented a way to guide the newly devised learning activities. The discussion in this article took into account the context and practice of narrative education, emphasizing that content related to academic understanding, the performance of practical activities, attitudes, ethics and contexts in narrative education should be implemented as learning activities. In addition, it was made to emphasize that learning activities in narrative education cannot be far from the learning activities presented in the textbook, namely basic learning and practical learning. Through this, the study was able to create a new orientation for narrative education at school sites.

The Efficient H.264 Baseline Profile Decoder for Mobile Device

Juwon Byun,Jinha Choi,Myungsuk Oh,Jaeseok Kim 대한전자공학회 2008 ICEIC:International Conference on Electronics, Inf Vol.1 No.1

This paper proposes an efficient motion compensation interpolation and CAVLD (Context - Adaptive Variable Length Decoder) architecture for H.264/AVC Baseline profile Decoder. The proposed interpolation architecture eliminates time irregularly and redundant calculation with merged 6x6 tap filter. The proposed CAVLD architecture adapts two techniques to reduce the computational cycles for valid bits. One is an improved reducing decoding step and the other is to get the valid bits directly by shifting additional shift register. H.264/AVC Baseline profile decoder system with proposed architectures is implemented by 0.18 CMOS library with 200K logic gates.

S-268 Impact of cannula size on clinical outcomes in venoarterial extracorporeal membrane oxygenation

( Juwon Kim ),( Jeong Hoon Yang ) 대한내과학회 2016 대한내과학회 추계학술대회 Vol.2016 No.1

Background:?Venoarterial extracorporeal membrane oxygenation (VA ECMO) is an effective mechanical circulatory support for cardiopulmonary failure. Conventionally, arterial cannula over 15Fr is inserted for full circulatory support in peripheral VA ECMO. However, limited data are available on clinical impact of cannula size.?Methods:?Between January 2014 and April 2016, 168 patients underwent peripheral VA ECMO were enrolled in a single-center registry. We classified patients into 2 groups according to the arterial cannula size: Group 1 (smaller arterial cannula with 14-15Fr, n=87) and Group 2 (larger arterial cannula with 16-24Fr, n=81). We compared the clinical outcomes and procedure related complications between the two groups.?Results:?In-hospital mortality (48.3% in Group 1 vs 42.0% in Group 2; p=0.41) and weaning success rate (70.1% in Group 1 vs 65.4% in Group 2; p=0.52) were not significantly different between the two groups. Group 1 showed significantly lower initial pump flow (3.2 [2.5-3.7] vs 3.5 [3.0-4.0] L/min; p=0.01) and ECMO duration time (3 [1-5] vs 4 [1-8] day; p=0.01). Limb ischemia was significantly lower in Group 1 than that in Group 2 (4.6% vs 14.8%; p=0.02). But other complications (including cannula site or non-cannula site bleeding, thrombotic events, coagulopathy and sepsis) were not significantly different between the two groups.?Conclusions:?In peripheral VA ECMO, small arterial cannula strategy showed similar clinical outcomes compared with large arterial cannula strategy. Additionally, small arterial cannula strategy provided advantage in terms of limb ischemia.

Intentionality and Conative Constructions in English

Juwon Lee 한국중원언어학회 2016 언어학연구 Vol.0 No.41

The primary purpose of this paper is to investigate the relation between intentionality and affectedness. Specifically, I make a semantic generalization called the Complementarity of Intentionality and Affectedness (CIA), which states that intentionality and affectedness cannot be entailed in a minimal accomplishment predicate (the combination of a verb and its complement(s) which is a causative accomplishment) at the same time. This mutual exclusivity of entailments of intentionality and affectedness is observed in Korean accomplishment predicates, which have multiple readings in which either the subject is necessarily intentional or the patient is necessarily affected, but not both. After the introduction of the CIA, I argue that English conative alternations are an instance of the CIA: The conative constructions (e.g. He kicked at the ball) entail intentionality, but not affectedness; on the contrary the corresponding transitive verb constructions (e.g. He kicked the ball) entail affectedness, but not intentionality. Finally, I discuss some predictions of the generalization and argue that the CIA can be further supported cross-linguistically.

Mode Selection of Leaky Lamb Waves in Steel Plate

JUWON LEE,WON-BAE NA,JEONG-TAE KIM,HYUN-MAN CHO 한국해양공학회 2008 韓國海洋工學會誌 Vol.22 No.1

The dispersion and attenuation of Lamb and Leaky Lamb waves propagating in a 1 ㎜-thick steel plate wave investigated. For acquiring a long (or large) range inspection capability, the fundamental symmetric and anti-symmetric wave modes (SO and AO) aver lowe frequencies were studied. Based on the dispersion curves, as well as pitch-catch and multi-mode simulations, it was shown that the SO mode over low frequencies is the proper mode to minimize the dispersion and attenuation. In addition, it was shown that the SO mode couldbe easily distinguished under multi-mode simulation since it has a larger group velocity than the AO mode.

The Complementarity of Intentionality and Affectedness: Evidence from English Verbs of Killing

( Juwon Lee ),( Kyung Hee ) 한국언어정보학회 2018 언어와 정보 Vol.22 No.3

The primary purpose of this article is to empirically support a semantic hypothesis, the Complementarity of Intentionality and Affectedness (J. Lee, 2016), according to which a minimal accomplishment predicate (the combination of a verb and its complement(s) which is a causative accomplishment) cannot entail intention and result simultaneously. This semantic principle was initially proposed based on the interpretations of Korean accomplishment predicates and English conative alternations (J. Lee, 2016). However, some English verbs of killing (e.g., murder) are strong potential counterexamples to the hypothesis, since at first glance they appear to entail both intention and result at the same time (Dowty, 1991; Talmy, 1985; Lemmens, 1998; Kamp, 1999-2007; inter alia). In this paper, I present the data involving English verbs of killing collected from the Web, and argue that the English verbs of killing do not actually entail intention, so they are not a problem with the hypothesis, but rather they support it.

A Study on the Transition Strategy of Military Service in Korea Using PEST-SWOT-FUZZY-AHP

Juwon Park(박주원),Wonseok Kang(강원석) 이화여자대학교 경영연구소 2021 신산업경영저널 Vol.39 No.1

최근 병역 면제와 대법원의 양심적 병역거부자에 대한 무죄 선고는 군 복무의 부당성에 대한 대중의 인식을 높였고 군 제도의 변화에 대한 정치인들의 논쟁을 가속화시켰다. 특히 첨단 기술 군으로의 양상전환 및 출산율 감소로 인한 인구 감소도 병역제도의 변화를 요구하고 있다. 병역제도 개편은 현재 국내에서 유지되고 있는 징병제에서 지원자를 직업군인으로 모집해 군을 유지하는 모병제도를 말한다. 이러한 배경에서 이 연구는 PEST-SWOT-FUZZ-AHP 분석에 기초해 현재의 군복무 전환 전략의 도입에서 발생하는 질적 한계를 극복하기 위해 의사결정자의 대응 신뢰도를 반영하는 정량적 방법론을 사용했으며, 전략적인 도구로서 SWOT 요소별 중요도와 그에 따른 전략을 제시하였다. 분석 결과 강점 요인에서는 ‘병력 구조 개편 및 감축 가속화’, 약점에서는 ‘병역 자원 확보의 어려움’이 가장 중요한 요인으로 나타났으며 기회요인에서는 ‘국민의 지지증가’가 가장 중요한 요인으로 도출 되었고 마지막으로 위협 요인에서는 ‘예산 확보의 어려움’이 가장 중요한 요인으로 도출되었다. 이를 바탕으로 SO, WO, WT, ST전략의 상대적 중요도와 각각에 맞는 전략을 제시하였으며 SO전략은 병력 구조개편을 통해 전문성을 확보하고 이를 바탕으로 국민의 지지를 얻는 전략, WO전략은 군 내부마케팅을 바탕으로 공감대를 형성하고 병역 자원을 확보하고 국민의 지지를 얻기 위한 공보 전략, ST전략은 군의 전문화, 첨단화에 필요한 예산을 우선적으로 확보하는 전략, WT전략은 병역 자원 확보를 위한 군인의 직업적 혜택을 증가하는 예산을 우선적으로 확보하는 전략이 도출되었다. 이는 단기적으로 한국의 상황에 맞는 동태적 SWOT전략으로 WT전략-WO전략-SO전략을 제시한 것이며, 병역제도의 변화에 대응하는 전략을 개발하기 위한 정량적 방법의 사용을 보여주었다. The recent military service exemption and the Supreme Courts acquittal of conscientious objectors increased public awareness of the unfairness of the military service and accelerated the debate among politicians about a change in the military system. Particularly, the population decline due to the decreasing birth rate and a transition to high-tech military warfare are also calling for a change in the military service system. The change in the military service system refers to a change from the current conscription system maintained in Korea to the recruitment system, which is a system that forces the people to serve in the military, and the recruitment system refers to a system that maintains the military by recruiting applicants as professional soldiers. Against this backdrop, based on the PEST-SWOT-FUZZY-AHP analysis, this study used quantitative methodologies reflecting the response reliability of decision makers to overcome qualitative limitations emerging from the introduction of the current military service transition strategy. The study also aims to present the importance of each SWOT element as a strategic tool. The analysis revealed “the reinforcement of military structure and accelerating troop reduction”, “difficulty in securing military resources,” “an increase in public support,” and “difficulty in securing a budget” as most important strength, weakness, opportunity, and threat, respectively. The results lead to the following strategies: reinforcing military structure; drawing public support; building consensus based on internal military marketing; and securing budget for enhancing specialization, providing state-of-the-art military service, and procuring military resources This shows that the dynamic WT-WO-SO (SWOT) strategies can contribute toward the current positive scenario in Korea in the short-term. The study shows the use of quantitative methods for developing strategies in response to the change in the military service system.
