본 연구에서는 강섬유 혹은 폴리프로필렌 섬유로 하이브리드 보강되고, 수직하중과 수평하중을 받는 고강도 콘크리트 내민받침을 제작하고 실험하였다. 실험 결과, 강섬유, 폴리프로필렌 섬유를 혼입함에 따라 내하력, 강성, 연성, 균열폭, 균열 수 측면에서 고강도콘크리트 내민받침의 성능은 향상되었다. 폴리프로필렌 섬유로 보강된 고강도콘크리트 내민받침은 강섬유로 보강된 내민받침보다 다소 낮은 내하력을 보였지만, 수평하중 하에서 더 큰 연성을 보였다. 또한, 주인장 타이 철근으로 사용된 헤디드 바의 헤드는 뛰어난 정착을 보여주었다. 실험 결과를 설계기준의 규준식 및 여러 연구자들이 제안한 예측모델과 비교한 결과, 정밀 스트럿-타이 모델이 수평하중 하에서 가장 정확하고 보수적인 예측 결과를 보여주었고, Fattuhi가 제안한 트러스 모델은 섬유 보강 고강도콘크리트 내민받침의 강도를 잘 예측하는 것으로 나타났다.

In this study, high strength concrete corbels reinforced with steel fibers and polypropylene fibers, and subjected to the vertical and horizontal loads were constructed and tested. The results showed that performance in terms of load carrying capacities, stiffness, ductility, crack width, and number of cracks was improved, as the steel fibers and polypropylene fibers were added. The polypropylene fiber reinforced concrete corbels resulted in higher ductility in presence of horizontal loads, but showed larger crack width than the steel fiber reinforced concrete corbels. And, the heads of the headed bars provided excellent end anchorage of the main tension tie reinforcement. Experimental results presented in this paper are also compared with various prediction models proposed by codes and researchers. The refined strut-and-tie model showed more accurate and conservative predictions in presence of horizontal loads, and the truss model proposed by Fattuhi provides fairly good predictions for fiber reinforced concrete corbels.

The risk of bearing failure is evaluated through the seismic response analysis of a bridge considering the probabilistic characteristics of structural properties such as the mass of superstructure, the stiffness of pier, and the translational and rotational stiffness of the foundation as well as seismic loadings during the bridge service lift. The effect of pounding between adjacent vibration units on the risk of bearing failure is also investigated. The probabilistic characteristics of structural properties are obtained by the Monte Carlo simulations based on the probabilistic characteristics of basic random variables included in the structural properties. From the simulation results, the failure probability of fixed bearings attached on the abutment is found to be much higher than those placed on the piers. It is also found that the pounding effect significantly increases the failure probability of bearings. In the simply supported bridges, the risk of bearing failure increases as the number of bridge spans increase. Therefore, the failure probability of fixed bearing due to the effects of pounding phenomena and the number of bridge spans should be considered in the seismic desist of bearings.

Recently, the number of seismically isolated bridges increased suddenly since the occurrence of strong earthquakes. However, because isolator lies between pier and girder, the response of the superstructure of seismically isolated bridge may be magnified and induce risk of unseating girder Consequently, the response of girder constitutes a crucial factor in designing bridge. In the case of frictional bearing, the inherent nonlinearity makes the use of former linear response spectrum unable to estimate the maximum response of the bearing, and nonlinear tlme history analysis shall be applied. In this paper, nonlinear response spectrum considering frictional element is established, and simple analysis method using such nonlinear spectrum is proposed to estimate the maximum response of the superstructure.

Earthquake damage civil engineering structures every year in the world and bridges are no exception. Bridge structures have proven to be vulnerable to earthquake, sustaining damage to substructure and foundation and being totally destroys as superstructures collapse from their supporting elements. The poor seismic performance of bridge structures is surprising in view of the substantial advance made in design and construction for vertical load. Recently, bridge spans have been pushed further than before, alignment has become increasingly complex and aesthetic requirement have been become more demanding. To reduce the seismic force and to improve the safety of the advanced bridges, the bridge bearings which are the substructures and foundations and their connections to the superstructure become more important and critical elements. Therefore, the functions about seismic devices to be using as bridge bearing are discussed.

이 연구에서는 강섬유 혼입률과 주인장 철근의 정착 방법을 변수로 한 섬유보강 고강도 콘크리트 내민받침을 제작하고 구조실험을 실시하였다. 강섬유의 혼입, 강섬유 혼입률의 증가에 따라 고강도 콘크리트 내민받침의 내하력, 강성, 연성은 증가하는 것으로 나타났고, 최대 균열폭은 감소하였다. 또한, 횡방향 철근에 용접하여 주인장 타이 철근을 정착한 내민받침 보다 헤디드 바를 주인장 타이 철근으로 사용한 내민받침이 더 높은 내하력, 강성, 연성을 보였다. 따라서, 헤디드 바를 주인장 타이 철근으로 사용하고, 강섬유를 혼입함으로써 내민받침의 내하력, 내구성, 시공성 등을 향상시킬 수 있을 것으로 판단된다. 실험 결과를 설계기준의 규준식 및 여러 연구자들이 제안한 예측모델과 비교한 결과, Fattuhi가 제안한 트러스 모델은 섬유 보강 고강도 콘크리트 내민받침의 강도를 잘 예측하는 것으로 나타났다.

High-strength concrete corbels with varying percentage of steel fibers and two different anchorage types (welding to transverse bar, headed) for the main tension tie were constructed and tested. The results showed that performance in terms of load carrying capacities, stiffness, ductility, and crack width was improved, as the percentage of steel fibers was increased. In addition, the corbel specimens in which headed bars were used as the main tension tie reinforcements showed superior load carrying capacities, stiffness, and ductility compared to the corbel specimens in which the main tension ties were anchored by welding to the transverse bars. From the test results, it is expected that load carrying capacities, durability, and constructibility of high strength concrete corbels would be improved by using steel fibers and headed bars. Experimental results presented in this paper were also compared with various prediction models proposed by researchers and presented in codes. The truss model proposed by Fattuhi provides fairly good predictions for fiber reinforced high-strength concrete corbels.

The vibration modes of resilient mounting system and foundation structure which support diesel engine/generator set and acoustic enclosure walls play an important role in the vibration transmission process. So, it is necessary to perform vibration mode analysis of resilient mounting system and foundation structure. For some reasons, if the vibration modal analysis of resilient mounting system and foundation structure of acoustic enclosure could be simultaneously done by finite element method, it would be very efficient approach. In this paper, vibration modal analysis method using finite element method for multi stage mounting system having n d.o.f model was proposed. Vibration analysis of single and double stage resilient mounting system was performed to verify the validity of the proposed method. Also frequency response results were compared in case of rigid foundation model and finite element foundation model which was compared with experimental modal analysis results.

Background: A forward head posture (FHP) is one of the most common types of poor head posture in patients with neck disorder. A prolonged FHP might increase pressure on the posterior cranio-cervical structure and exhibit reduced performance on a cranio-cervical flexion test (CCFT). CCFT is included to activate deep cervical flexor muscles and inhibit excessive activation of superficial cervical flexor muscles. Therefore, the selective activation of deep cervical flexors is needed for effective exercise for FHP. Objects: The purpose of this study was to compare muscle thickness between longus colli (Lco) and sternocleidomastoid (SCM) using ultrasonography in subjects with FHP depending on head support. Methods: This was a cross-sectional, case-control research design study. The ultrasonographic images of Lco and SCM were taken in 17 subjects with FHP during the 5 phases of the CCFT with and without a head support. Towel was used for supporting head to make the neutral head position in supine. Changes in muscle thickness during the test were calculated to infer muscle activation. Data were analyzed using repeated measures of two-way analysis of variance with the significance level of .05. Results: When subjects performed the CCFT with head support, there was a significant difference in muscle thickness of Lco and SCM (p<.05). According to a post hoc paired t-test, change of thickness of Lco was greater at all phases, and change of thickness of SCM muscle was less at phase 4 and 5 in condition with head support (p<.01) compared to condition without head support (p<.01). Conclusion: The result of this study suggest that applying head support for neutral head position during CCFT could be a useful method for activating Lco muscle without excessive activation of SCM muscle.

This study attempted to find out how lexical decision of two-syllable words or pseudo-words is affected by syllabic information, such as syllable frequency, syllable (i.e. vowel) type, and presence of final consonant (i.e. batchim), through the analysis of the Korean Lexicon Project Database (KLP-DB). Hierarchical regression of RT data showed that lexical decision of words was influenced by the frequency of the first syllable, the syllable type of the first and second syllables, batchim for the first and second syllables, and also by the interaction of the two syllable types and the interaction of syllable frequency and batchim of the second syllable. For pseudo-words lexical decision was influenced by the frequency of the first and second syllables, syllable type of the first syllable, and batchim for the first and second syllables, and also by the interaction of the two syllable frequencies, the interaction of the two syllable types, and the interaction of syllable frequency and batchim of the first syllable. Word frequency had a strong effect on lexical decision of words, while syllabic information had a stable effect on the lexical decision of pseudo-words. These results indicate that syllabic information should be seriously considered in constructing word and pseudo-word lists and interpreting lexical decision time. Understanding the effect of syllabic information will also contribute to the understanding of word recognition process.

This study assesses how orthographic rules are presented in South Korea, North Korea, and China, with an emphasis on general provisions, graphemes, and final consonants. In analyzing general provisions, the study scrutinizes the principles of orthographic rules employing formalism and phonemicism to highlight differences in implementation across these countries. In the section on graphemes, the study investigates the introduction methods of consonant and vowel graphemes, including their naming conventions and dictionary applications. Each country employs unique compositional strategies based on set criteria. Regarding the presentation of final consonants, South Korea includes them in the Commentary on Korean Orthography, whereas North Korea and China integrate them directly into their orthographic rules. Noteworthy differences are observed in the sequence of presentation and the approaches applied to formulate examples.

배경 및 목적: 최근 아동 및 청소년들의 철자의 수행에 대한 관심은 높으나 철자 수행 수준을 세분화하여 측정할 수 있는 검사가 부족하다. 또한 기반이 되는 철자 연구에서 철자 수행 수준에 영향을 미칠 수 있는 낱말 친숙도가 고려되지 않아서 친숙도가 철자 수행에 있어서 어떤 영향력을 미칠지 검증되지 않았다. 그러므로 학령기 읽기장애 아동과 일반 아동을 대상으로 친숙도 정도 및 음운규칙 적용 유무에 따라서 철자법에 맞게 낱말을 쓰는 능력과 지각하는 능력의 수행 차이가 있는지 비교하여 읽기장애 아동들의 받침철자 특성에 대한 정보를 제공함으로써 효과적인 받침철자 평가 및 중재 방안을 모색하고자 하였다. 방법: 초등학교 4∼5학년 읽기장애 아동 20명과 성별, 학년, 및 생활연령을 일치시킨 일반아동 20명, 총 40명을 대상으로 친숙도 및 음운규칙 적용 유무에 따라 문맥 안에서의 받침철자 쓰기와 인식과제를 실시하였다. 분석결과는 집단을 집단 간 요인으로 과제유형과 친숙도/음운규칙을 집단 내 요인으로 하여 3요인 혼합분산분석을 실시하였다. 결과: (1) 친숙도에 따른 받침철자 정반응률과 과제 유형에 따른 받침철자 정반응률은 집단 간 유의미한 차이를 보였고, 집단 내 변인에서는 과제유형과 친숙도의 주효과가 유의하게 나타났으나, 상호작용은 친숙도와 집단 간 이차상호작용만 유의하였다.(2) 음운규칙 적용 유무에 따른 받침철자 정반응률도 집단 간 유의미한 차이를 보였고, 집단 내 변인에서도 음운규칙 적용 유무의 주효과가 유의하게 나타났다. 상호작용은 모든 요인들 사이에서 유의하게 나타났다. 논의 및 결론: 읽기장애 아동은 친숙도가 낮은 낱말과 음운규칙이 적용되는 낱말의 받침철자법에 대한 이해가 부족한 것으로 나타났다. 또한 받침철자법에서 음운처리 능력의 문제도 작용하는 것으로 나타났다. 이러한 결과는 받침철자 능력을 평가하고 중재할 때, 친숙도가 고려되어야 한다는 것과, 중재 시에 한국어 음운규칙 및 철자 발달단계에 대한 내용을 적용하는 것이 효과적일 수 있음을 시사한다.

Background & Objectives: The purposes of this study were 1) to examine whether there are significant differences in accuracy depending on the type of tasks and word familiarity in children with reading disabilities compared to those in the age-matched typically developing children, 2) to examine whether there were significant differences in accuracy depending on the task type and the existence of phonological rules between the groups, and 3) to investigate the types of spelling errors in the spelling dictation and recognition tasks in children with reading disabilities and the control group. Methods: A total of 40 children participated in the study, including 20 children with reading disabilities (RD) and 20 age-matched typically developing children (TD). The children were fourth- and fifth-graders from the same elementary school. Dictation and recognition tasks were developed for this study, each consisting of 42 words. The words were divided into familiar and unfamiliar word groups according to the existence of phonological rules such as liaison, aspiration, neutralization, consonant cluster simplification, and consonant assimilation. A three-way mixed ANOVA was computed with the group as a between-subject factor and the type of task and word-familiarity as within-subject factors. Results: 1. There was a significant main effect for the children with RD showing significantly worse performance than that of the TD group, with better performance shown with the familiar words compared to that of the unfamiliar word. 2. There was a significant main effect of group, showing that children with RD performed significantly worse than did the age-matched control children, with better performance shown for words with phonological rules compared to that of words with no phonological rules. 3. Both groups showed similar error patterns in the final consonants, including those of both phonetic and replacement errors. However, children with RD showed more frequent errors in the words with final consonant clusters and final consonant rules than did the age-matched control group. Discussion & Conclusions: Greater differences were observed in children with RD compared to that of those in the TD group as a function of task type and phonological rules. The error types regarding the phonological rule were consistent in RD children, whereas they were not consistent in the age-matched control group.

The purpose of this study is to research characteristic and cause of phoneme of interlanguage by analyzing the consonant pronunciation mistake of Chinese speaker, who studies Korean language and survey the effect of pronunciation education and change of interlanguage on the basis of it. From the aspect of government phonology, English and Korean language belong to the language that permits empty nucleus in the end of syllable but Chinese language belongs to the language that does not permit empty nucleus. Therefore, syllabic structures of both languages are different. From the result of contrastive analysis, Chinese learners, who are familiar with the language without consonant, have difficulties in pronunciation and recognition of Korean language with consonant. It was possible to predict that they will make mistakes in the pronunciation of Korean consonant and it was found that there were many mistakes in actual experiment, The study compared the effect of pronunciation education on the basis of interlanguage to that of general education. It was found that the pronunciation education, which was adjusted for Chinese learner’s mistake on the basis of interlanguage, was effective to some extent.

The main purpose of this paper is to examine the pattern and the characteristics of exclamatory sentences according to the aspects of cognitive working of Korean. Since the researches of such sentences have mainly been achieved in terms of the classification of type of sentences, researches of ‘-ku-’ class final ending , such as ‘-ku, -kuna', or the mood-related take most parts. The main interests of this research are to establish the boundary of the exclamatory sentences in terms of pragmatics in a broad sense; to set it up extensively; and to study the aspects of cognitive working when we speak to exclamatory sentences. The exclamatory sentences can be classified into two types: 1. reflected exclamatory sentences: instant expression when a person responses from a stimulus 2. cognitive exclamatory sentences: relatively more lagged responses than reflected exclamatory sentences due to time required to think and response.

Young-hae Yoon. 2007. An Analysis of Inerlanguage Phonology found among Korean Learning Chinese and Japanese from the Viewpoint of Goverment Phonology. Language and Linguistics 39, 113-130. As a view of government phonology, this thesis analyzes interlanguage phenomenon that is frequently misused by Chinese and Japanese when they learn Korean. The interlanguage phonology is able to divide into segment, sound alteration, syllabic structure. The aspect of inter-language can be verified by observing errors which are appeared each part of phonology. Errors, that are occurred when foreigners speak the Korean consonant and when speaking the segment-sound (the double-vowel /ㅖ/ and the singular-vowel /ㅐ/), are explained by syllable-structure and element of governmental phonology. Japanese and Chinese have a fundamentally different syllable- structure because they don't speak the domain-final empty nucleus. So they often make errors when they speak Korean by excepting Korean consonant or inserting the vowel /ㅡ/. These errors appear when speaking Korean by changing construction elements to follow Chinese phoneme- system because, in the segment, phoneme-system isn't same between Korean and Chinese.

The purpose of this study was to examine the effects of synthetic phonics-based phonological and orthographic processing spelling instruction on the spelling achievement of words without final consonants in elementary students with dyslexia and at-risk for dyslexia. An AB single-subject design consisting of baseline, intervention, and maintenance phases was used to measure spelling intervention effects for three first-grade students with dyslexia and at-risk for dyslexia attending an elementary school located in Incheon Metropolitan City. The results indicated that the spelling achievement of words without final consonants significantly improved for all three students. Additionally, maintenance assessments conducted for two students demonstrated sustained effects. Based on the findings, this study suggests that systematic and explicit synthetic phonics-based phonological and orthographic processing spelling instruction should be provided to students with dyslexia and at-risk for dyslexia during first-semester Korean language instruction for first graders in alignment with the 2022 Revised National Curriculum.

Purpose: This study aimed to investigate the effects of a 3D-model of Hangul syllabic structure intervention, based on the phonics approach, on the ability of children with reading disabilities to read final consonants. Method: A 3D-model of Hangul syllabic structure, highlighting its distinctive features of Hangul, was developed as the research tool. Using this model, a phonics approach intervention was conducted. The study participants were three elementary school children with reading disabilities. The research design employed a multiple probe design across a single subject design, with three baseline sessions, 15-17 intervention sessions, three generalization sessions, and three maintenance sessions. Results: The intervention based on the 3D-model of Hangul syllabic structure improved the final consonant reading ability of all three participants. Additionally, the effects of the intervention were generalized to untrained words. The improved reading performance was maintained even after a three-week follow-up period without intervention. Conclusion: These results suggest that a 3D-model of Hangul syllabic structure intervention based on the phonics approach is effective in improving the final consonant reading ability of children with reading disabilities.

The additional axial force of CWR(continuous welded rail) is occurred by structure-track interaction, in reverse, fixed supports of structure are applied the large load by that. Ratio of load which transferred on support through the bridge superstructure with one-side REJ by acceleration and braking load are stated in High-Speed Rail Design Criteria(2005). On the other hand the horizontal forces of support delivered to the load due to thermal loads has been no report about the criteria. Therefore, this study was performed the review of the reaction and displacement on support by structure-track interaction in a special bridge(composite brdiges, 45+55+55+45=200m) with REJ acting on the temperature load. As a result, because fixed support of a special bridge or a continuous bridge with REJ under the temperature load which is constant load has been acted the large lateral load by structure-track interaction, when determining the fixed bearing capacity of structure should be reflected in the results to secure the safety of structures was confirmed.
