In this study, load transfer tests based on KCI-PS101 were conducted to verify the performance of spiral anchorage zone reinforcement for banded post-tensioning (PT) monostrands. With results, the compressive strength of spiral reinforcement was increased by about 20% than that of specimens with two horizontal steel bars and 8% than that of U-shaped bars. Advanced spiral reinforcement for corner increases compressive strength and can resist the spalling forces or fall-out effect at the corner by shear. The ratio of maximum load to amount of steel of the spiral reinforcement is about twice than that of U-shaped reinforcement. With increase of compressive strength capacity and improvement of constructability, the spiral reinforcement is considered to have advantages of promoting the performance of PT anchorage zone compared to conventional methods.

To resolve the conservative requirements for clear headed-bar spacing in KBC 2016 and ACI 318-08, two 2/3-scale exterior beam-column connections were tested under cyclic seismic loading. The seismic tests primarily explored the effect on their seismic performance of using (a) small clear spacings and (b) multiple layers of headed reinforcements in the beam. Also, the previous test data were thoroughly analyzed. It was concluded that the clear bar spacing of 2db or the use of two bar layers might be permitted for headed reinforcements embedded in exterior beam-column connections. KBC 2016 및 ACI 318-08에서 확대머리 철근의 순간격에 대한 지나치게 엄격한 요구 사항을 개선하기 위해 2/3 스케일의 외부 보-기둥 접합부 실험체를 준정적 반복 하중을 적용하여 실험을 수행하였다. 내진 실험을 통해 좁은 간격의 철근 순간격과 다열 배치 확대머리 철근 적용여부를 주요 변수로 하여 내진 성능에 미치는 영향을 검토하였다. 또한, 본 실험결과를 이전 연구자들의 실험 데이터와 함께 면밀히 분석하였다. 결론적으로 외부 보-기둥 접합부에 정착된 확대머리 철근에 대해 2db의 철근 순간격 또는 2 개층의 확대머리 철근의 사용은 내진 설계에 있어 허용될 수 있는 것으로 판단된다.

This study examines how extreme negative rating reviews affect the usefulness of reviews among the factors that affect the usefulness of reviews, and analyzes how the characteristics of reviewers affect the usefulness of reviews in terms of the effects of extreme negative rating reviews on the usefulness of reviews. The results of the analysis were as follows. First, extreme negative reviews were found to have a positive effect on the usefulness of reviews, and H1 was adopted. Second, when extreme negative rating reviews affect the usefulness of reviews, we looked at the adjustment effect of reviewer reputation and found that the adjustment effect of reviewer"s reputation "friend count", "elite index" and "follower count" was statistically significant. H2-1 was chosen. Third, when extreme negative rating reviews affect the usefulness of the review, we looked at the adjustment effect of the reviewer"s expertise and found that the adjustment effect of the reviewer"s "usefulness vote" and "reviewer"s review count" was statistically significant. H2-2 has been adopted. Based on these findings, we would like to provide implications for the management and strategy of future online sales companies.

The in vitro alternative assay for evaluating skin sensitizing potentials (SSP) called human Cell Line Activation Test (h-CLAT) has been recently adopted as an international test guideline. The present study was proceeded to pursue the domestic establishment and expansion of h-CLAT. The standard operational procedure was prepared in detail by the lead laboratory (LL) and transferred to one participating laboratory (PL). The LL demonstrated technical proficiency for the 10 substances listed in OECD TG 442E. The PL also demonstrated a certain level of proficiency, in that 4-phenylenediamine and 4-aminobenzoic acid distributed with coded names were correctly classified as positive and negative on SSP, respectively, and other indices including 75% cell viability (CV75) and relative fluorescence intensity (RFI) % for CD54 and CD86 were fell within the reference range. Methyl methacrylate, nickel chloride, and resorcinol, which are inconsistent in predicting SSP through various alternative test methods, were unanimously predicted as negative, positive, and positive on SSP by the two laboratories for the first time through h-CLAT. Both chlorobenzene and sodium lauryl sulfate with the existing h-CLAT report as positive and negative, respectively, were predicted as negative by the PL, which could contribute toward overall categorization into non-skin sensitizer.
『課程日錄』의 어휘 분류체계 및 ‘身體’ 어휘의 의미 관계
조아람 반교어문학회 2019 泮橋語文硏究 Vol.0 No.51
본고는 분류어휘집인『과정일록』의 어휘 분류 체계를 살펴보고, ‘신체’문 어휘의 의미관계를 살펴 『과정일록』의 국어사적 가치를 규명하는 데에 목적이 있다. 『과정일록』은 두 가지 이본이 전하며, 일본의 오구라문고와 성균관대학교의 존경각에 각각 소장되어 있다. 어휘 분류는 약 9,000여 개의 어휘를 30개의 목록으로 나누어 싣고 있는데 천, 지, 인, 물 관련 어휘를 모두 다루고 있다는 점에서 만물류 물명서와 성격을 같이 하며, 제목을 과정에 대한 매일의 기록으로 볼 수 있다는 면에서 한어 학습서와 같은 성격도 있을 것으로 예상할 수 있다. ‘신체’ 관련 어휘는 오구라문고본 329개, 존경각본 328개를 다루고 있으며 몸, 장기, 얼굴, 상체, 하체, 행동, 분비물 등의 순으로 나열되어 있다. 그리고 그 어휘들과 관련이 있는 형용사와 동사를 함께 다루고 있다. 『과정일록』은 19~20세기에 사용되던 일상 어휘를 명사를 중심으로 형용사, 동사 등 전체를 아울러 다루고 있다는 점에서 국어사 어휘 연구에 중요한 자료가 될 수 있을 것으로 기대한다. The purpose of this study is to examine the lexical classification system of "Gwajeong-illok", which is a classification word collection, and to examine the semantic relation of the lexicon of "body" group, to establish the Korean history value of "Gwajeong-illok". There are two types of "Gwajeong-illok" and are kept in the Ogura Mungo of Japan and in the Jongyeonggak of Sungkyunkwan University. The "Gwajeong-illok" contains about 9,000 words divided into 30 lists. It has all the vocabulary associated with '天, 地, 人, and 物,' so it has a similar personality to 'Manmul-lyu Mulmyeong-seo'. Also, since the title is a daily record of the process, it is similar in character to the Chinese language study book. There are 329 vocabulary in the "body" group in version of Ogura Mungo, and 328 in the "body" group in version of Jongyeonggak. Words related in "Body, organs, face, upper body, lower body, action, secretion" are listed in order. It is also listed with adjectives and verbs related to the word. It is expected that "Gwajeong-illok" will be an important resource for Korean language vocabulary research because it has all the nouns, adjectives, and verbs used in the 19th and 20th century.
