This study proposes a novel method for in service evaluation of tension force of a prestressed 7-wire strand which is frequently employed for retrofitting bridge superstructure. The smart strand is made by replacing the straight king wire of the strand with an instrumented steel tube in which the FBG sensor is embedded. Since the strain of the smart strand can easily be measured using the sensor, it is possible to monitor tension force of the strand during the service. For the sake of demonstrating effectiveness of the proposed strand, we came up with a 7.0m long prototype with 2 FBG sensors, and it is applied as an external tendon to a 6.4m long and 0.6 high RC T-shaped beam. A loading-unloading test has been carried out, and estimated tension forces using the smart strand are compared with measured forces by load cell. The comparison showed that the proposed smart tendon is useful and accurate for monitering tension force of the prestressed tendon.

Kim, Jae-Min. 1999. Thematic Relationship in Small Clauses. Linguistics 7-2, 61-76. The propose of this paper is to discuss the internal structure of small clauses, based on the thematic relationship. I here reject Contreas`(1995) [+V] [-V] classification, which is solely based on the grammatical category of the predicate of the small clauses, and Bowers` (1992) PrP analysis, which is useful only for complement small clauses. Following Uniform Theta Assignment Hypothesis(UTAH), X` theory, and VP-shell structure, I argue that there are two different kinds of small clauses; one is that which allows the verb-raising in the light verb structure, the other one is that which has the [-raising] feature that prevents the empty verb from raising.

An Analysis of English Inversion : A Discourse Perspective

김재민(Jae Min Kim) 대한언어학회 2000 언어학 Vol.8 No.2

Kim, Jae-Min. 2000. An Analysis of English Inversion: A Discourse Perspective. Linguistics 8-2, 43-58. This paper presents a discourse-functional account of English inversion. To remedy the short-comings of Old/New information-packaging explanation for inversion, Birner (1994) suggests the notion of familiarity. I, however, have argued that though Birner`s familiarity model explains inversion well, some more functional principles are needed to explain it appropriately. Here, I have suggested three additional principles that trigger inversion: (i) Topic continuity principle, (ii) Focus/Topicality principle, and (iii) Subjectivity principle. I think they co-work to make inversion occur in discourse context. (Chonbuk National University)

Purpose: The aging of society has rapidly progressed, especially in Korea. Therefore, the necessity of research on end-of-life (EOL) care in elderly patients has increased. However, there are few studies on EOL care intensity for non-cancer patients. This study was designed to compare the EOL care intensity between cancer and non-cancer patients. Methods: We retrospectively analyzed the EOL care intensity based on medical records of decedents of Kyung Hee University Medical Center, a tertiary referral hospital from December 2014 through March 2015. And we compared EOL care intensity between cancer patients and non-cancer patients using statistical analysis of the frequency of invasive procedures and logistic regression analysis for factors that affect the EOL care intensity. Results: Statistical analysis showed invasive procedures, such as intensive care unit admission, endotracheal intubation followed by mechanical ventilation and emergency dialysis, were performed more frequently in non-cancer patients than cancer patients (29.3% vs. 72.4%, P<0.001). And age (P=0.038) and morbidity of cancer (P<0.001) influenced the invasive procedural decision when analyzed by logistic regression analysis. Conclusion: The EOL care was more intensive in non-cancer patients, and age and morbidity of cancer were major factors for the treatment intensity.

선형탄성해석과 m_α-tangent방법을 이용한 배관 한계하중 평가 적용성

김재민,김상현,배경동,김윤재,김종성,Gim, Jae-Min,Kim, Sang-Hyun,Bae, Kyung-Dong,Kim, Yun-Jae,Kim, Jong-Sung 대한기계학회 2017 大韓機械學會論文集A Vol.41 No.6

본 연구에서는 선형탄성 유한요소해석 방법과 $m_{\alpha}-tangent$ 방법으로 한계하중을 계산하고 이를 기존의 연구들에 의해 제시된 한계하중 식들과 비교하였다. 해석의 대상은 배관계의 대표 형상인 곡관과분기관을 선정하였다. 곡관과 분기관의 형상 변수를 다양하게 바꿔가면서 $m_{\alpha}-tangent$ 방법의 적용가능성을 살펴보았다. 하중은 내압하중과 면내굽힘하중을 각각 고려하였으며 곡관의 경우에는 기존의 한계하중식과 $m_{\alpha}-tangent$방법이 비교적 잘 일치함을 확인하였다. 하지만 분기관의 경우 형상의 특수성으로 인해 뚜렷한 경향 없이 기존의 한계하중 식과 $m_{\alpha}-tangent$ 방법이 일치하지 않는 것을 확인할 수 있었다. 이는 $m_{\alpha}-tangent$ 방법이 불연속부의 응력집중현상에 의해 왜곡된 결과를 갖기 때문으로 보인다. In this study, the limit loads calculated by the $m_{\alpha}-tangent$ method based on the linear finite element analysis are compared with the closed form solutions that are proposed by various authors. The objects of the analysis is to select the elbow and the branch pipe which are representative structure of piping system. The applicability of the $m_{\alpha}-tangent$ method are investigated by applying it to cases with various geometries. The internal pressure and the in-plane bending moment are considered and the $m_{\alpha}-tangent$ method is in good agreement with the existing solutions in case of elbows. However, the limit loads calculated by the $m_{\alpha}-tangent$ method for branch junctions do not agree well with the existing solutions and do not show any tendency. The reason is a biased result due to the stress concentration of the discontinuous parts.

Kim, Jae-Min and Park, Yun.-Ja. 2001. The Developmental Order and the Frequency Analysis of Textbooks for Wh-questions of English. The Linguistic Association of Korea Journal, 9(3), 89-108. It is observed that the children speaking English as mother tongue (LI) have the developmental order for Elf -questions . Also the children studying English as L2 showed the similar developmental order for English wh-questions The purpose of this study to the developmental order for wh-questions in Korean learners and the distribution for wh questions of English textbooks in middle school. The subjects consisted of 115 middle school students. They were tested by 36 wh-questions composed of 18 subjective questions and 18 objective questions. The results of this study showed that Korean students had the sae developmental order (where, what, who, how, why, when) for English wh-questions as L2. The results also Indicated that for the frequency distribution of wh-questions, English text books for middle school students Korea did not reflect the developmental order for English wh-questions (Chonbuk National University)

경어법 사용의 세대간 차이에 관한 사회언어학적 연구

Kim, Jae-Min. 1998. A Sociolinguistic Comparative Study of Korean Honorifics between Two Generations. Linguistics, 6-2, 337-357. Honorific expression in Korean is a very complicated system grammatically and socio-culturally. We assume that there should be some changes in the Korean honorific expressions between two generations, because the social structure is changing rapidly. In this paper I have tried to show the difference in honorific expressions between the two generations, the young generation of twenties and the fifties. As Brown and Gilman(1960) do, we think that the main factors that control the specific usage of honorific expression are power and solidarity. Also, we think that the main constituents of the power are age, gender, social status, etc. and those of the solidarity are familiarity, family member, same group, etc. I have used some statistical methods, like mean, X^2, and percentile, to show the appropriateness of the data analysis.
