RC Arch Deck Development and Performance Evaluation for Enhanced Deck Width

Dal?Hun Yang,Min?Jae Kwon,Gi?Ha Eom,Jang?Ho Jay Kim 한국콘크리트학회 2018 International Journal of Concrete Structures and M Vol.12 No.6

Due to extreme business competitions in bridge construction industries, the cost reduction became the most important issue in winning a contract bidding. The largest bridge construction cost saving can be obtained by using precasted construction method and by reducing required number of girders, columns, and decks in the bridge system. Therefore, an precasted arch deck system is proposed to widen the lateral span of the deck, which can result in reducing the number of required I-type PSC girders for construction cost saving. A usual lateral width of a flat deck is 1.5–2.0 m, but the width of arch deck is 2.5 m, an increase of 25–60%. Therefore, for a PSC girder bridge with a total width 10 m, a number of required girders needed for ordinary flat RC deck and arch deck is 5 and 4, respectively. This means that one less girder can be required, which means that 20% of girder construction cost can be achieved by using arch deck over ordinary flat deck. In this study, precasted RC arch deck is developed and manufactured to evaluate structural performance of the deck. The study results showed that arch deck has performance exceeding ordinary flat deck and can be used as alternative decks for precasted PSC I-girder bridge construction. The study results are discussed in detail in the paper.

전봉건『춘향연가』에 나타난 사랑의 윤리학

Previous studies on Chunhyang’s Love Song by Jeon Bong-geon provide planar interpretations about the different setting of characters from the original Chunhyangjeon and the reason why Chunhyang loved and waited for Lee Mong-ryong so much, oversimplifying her inner side depicted in Chunhyang’s Love Song. This study set out to investigate these issues in Chunhyang’s Love Song by Jeon Bong-geon through “ethics of love” to represent pure desire in Lacan’s psychoanalysis. Chunhyang meets Lee Mong-ryong who is a big other after passing through the “mirror stage” safely. Lee is “idealized” for his gorgeous appearance. She refuses to denounce her love for him despite Byeon Hakdo’s cruel torture because of the absence of Lee as an idealized other. Lee stands in the position of “empty other,” which makes even her inside confirmed of his not coming. In this way she shows “sublimated" love instead of falling in "idealized” or “perversive” love. Both Lee and Byeon Hakdo are the same big other to force the image of feudal “woman” on her. While Lee is a “sublimated” character as an “empty other” through the process of “idealization” for her, Byeon Hakdo represents the violent desire of forcing only “father’s law” on her. Since Lee’s love is more ethical than Byeon Hakdo’s love, Chunhyang helps Lee to be reborn as a subject of enjoyment called “Object a.” Jeon Bong-geon’s poetic achievements hold huge significance in that Chunhyang’s inner side is three-dimensional in Chunhyang’s Love Song.

This study is an attempt to present a model for a more reasonable, economical standard of an annual budget for the university and college library collection. The annual budgetary model for the annual increase of collection was calculated by a formula derived from a factor analysis of the fluctuations of external and internal mean price indexes. The result of this study is as follows: ⑴ The method of calculation for the study was employed by the following formula: For Korean books, B_Tn=V(c_(n-1)+C_(n-1)×33.8/100)……………………………………………………⑴ For Japanese books, B_Tn=V(c_(n-1)+C_(n-1)×19.2/100)×(E_(n-1)+E_(n-1)×22.7/100)………… ⑵ For western books, B_Tn=V(c_(n-1)+C_(n-1)×11.2/100)×(E_(n-1)+E_(n-1)×7.1/100) ………… ⑶ Total ⑴+⑵+⑶ ⑵ The result by the above formula is shown to 8,000 Won per student for 1975. Accordingly, the annual budget in future will have to be calculated by adding the rate of the price increase on the above result.

To examine what is caused by Contextual Interference in free throw, pass, dribble learning improvement closely, I made researches through a method to divide Chungnam Kongjusi C highschool thirty female students in ten students at random, and each of three group was named A group(blocked practice), B group (random practice), C group (serial practice), so the effect is as follows. 1. In free throw experimentation ( a people can shoot ten free throws in 4m) average marks obtained by A, B, C group are 2.4 point, 2.5 point, 2.4 point by turns before experimentation performance. to wit, their divergence is minute. But in retention phase and transfer phase that make us conclude whether or not the experimentation is useful learning, the average marks obtained by A is each 2.8point, 2.6 point and the improvement of A is a little. On the other hand, the marks by B is each 3.9point and 3.8 point, and the marks by C is each 3.8 point and 3.6 point and their improvements of B, C are much remarkable than A. to wit, in retention phase and transfer phase of free throw experimentation A group improved by 0.4 point, 0.2 point. B group is improved by 1.4 point, 1.3 point. and C group improved by 1.4 point and 1.2 point in the marks obtained. 2. In the passing experimentation (in this experimentation student should bounce pass the ball with both hands to the target of which diameter is 50cm and placed at 2.7m-far-wall) there wern't any remarkable difference among the average numbers that he succeed to pass the other per a sec of each team(A:31.0 times, B:31.1times , C:31.9times ) before the experimentation performed. But in the retention and transfer phase, group A showed a little advance (from 31.0 to 34.1, 33.2 times), on the other side group B and C showed a comparatively remarkable advance (B: from 31.1 to 37.9ㆍ36.7 times, C: from 31.9 to 37.3ㆍ37.0times). Namely in the retention and transfer phase of the passing experimentation group A had an increase by only 34.1 and 33.2 times but group B had an increase by 6.8 and 5.6 times and group C had an increase by 5.4 and 5.1 times. In short group B and C had a more remarkable improvement in this experimentation. 3. In the dribble experimentation (in this experimentation student should go and return as following zigzag course through five chairs that placed one by one keeping 3m distance) there wern't any remarkable difference among the average time required of each team(A: 16.32sec B: 17.10sec C: 16.70sec) before the experimentation performed. But in the retention and transfer phase group A showed a little renovating (15.60ㆍ15.89 sec), on the other side group B and C showed a comparatively remarkable renovating (B: 14.06ㆍ14.14sec C:14.30ㆍ14.66sec). Namely in the retention and transfer step of the dribble experimentation group A noted a renovating by only 0.72 and 0.43 sec but group B noted a renovating by 3.04 and 2.96 sec and group C noted a renovating by 2.40 and 2.04 sec. Consequently group B and C showed a large renovating than group A. So I reached a conclude based on the experimentation that B group (random practice) and C group ( serial practice ) had higher problem-solution-ability made by higher contentual interference , and useful learning is conducted by this method, so it is considered very suitable as a basketball game form. Therefore to generalize the effect of Contextual Interference, these experimentation should be conducted in more various events, and long in existence.

라틴아메리카의 정치문화와 민족주의

김달용 조선대학교 인문과학연구소 1999 인문과학연구 Vol.21 No.-

La colonizacio´n ibe´rica del Mundo Nuevo que comenzo´ a partir del siglo dieciseis teni´a como objeto no so´lo la borradura de la cultura indi´gena sino tambie´n la cristianizacio´n de la poblacio´n abori´gena. Los conquistadores iberos establecieron gran asentamiento de los indios, es decir, la comunidad indi´gena a fin de movilizar fa´cilmente fuerzas laborales que se utilizaban en minas y fincas de campo. Para tal propo´sito, ellos pusieron en pra´ctica un sistema del control de los indios en una manera sistema´tica, lo cual se denomino´ "encomienda" asi´ como "mita". Entonces, la encomienda se baso´ en latifundio que era gran finca de compo en donde una sociedad de autosuficiencia se manteni´a bajo la gobernacio´n de un encomendero. En esta comunidad, el encomendero teni´a absoluto derecho de utilizar las fuerzas laborales indi´genas, en cambio, e´l teni´a una responsabilidad de cuidar a los indios. En este contexto, las relaciones de "Patro´n y Peo´n" tempranamente se establecieron, las cuales se sentaron como la base de crear varias formas de cultura poli´tica tales como personalismo, clientelismo, particularismo, elitismo, machismo y caudillismo, etc. Desde el punto de vista de sus rai´ses, las citadas culturas poli´ticas teni´an la base tradicional de rai´ses intelectuales de monismo. Sin embatgo, despue´s de ser lograda la independencia a pricipios del siglo diecinueve, varias ideologi´as occidentales tales como liberalismo, pluralismo, socialismo y positivismo han fluido en Ame´rica Latina y Ame´rica Latina pareci´a convertirse en una meca ideolo´gica. Las ideologi´as occidentales se diseminaban en las sociedades latinoamericanas y a veces se fusionaron en las ideologi´as auto´ctonas, formando las nuevas ideologi´as de socialdemocratismo, cristianodemocratismo, socialismo y aprismo, etc. Desde entonces, el nacionalismo latinoamericano empezo´ a brotarse de las culturales poli´ticas y ideolo´gicas existentes que se relacionaban i´ntimamente unos a otros. En conjunto, el nacionalismo tiene la base de la leatad de pueblo a la nacio´n asi´ como de los factores comu´nes tales como idioma, cultura, religio´n, raza y forma poli´tica, etc. En este sentido, el nacionalismo latinoamericano ha concebido la naturaleza de homogeneidad cultural y de xenofobia a las fuerzas extranjeras. Sin embargo, el nacionalismo latinoamericano a veces tomaba ambigu¨edad ideolo´gica debido a su diversidad cultural, social y poli´tica. Y eso teni´a una tendencia de tomar varias formas flexibles bajo sus circunstancias. Como prueba, el nacionalismo latinoamericano en la e´poca colonial, se ha expuesto del logro de la independencia contra los colonizadores espan~oles y portugueses. En contraste, el nacionalismo del peri´odo de Porfirio Di´az en Me´xico representaba la modernizacio´n del pai´s, el cual justificaba muchas inversiones extranjeras. Adema´s, a partir de la segunda parte del siglo veintinueve, se apareciaba el nacionalismo como lo popular que se relaciono´ directamente a la modernizacio´n. Desde el punto de vista e´tnico y auto´ctono, el nacionalismo latinoamericano se representaba como los factores raciales integrados basados en "la Raza Co´smica". Al igual modo, desde el punto de vista ideolo´gico, el fascismo occidental contribuyo´ a una creacio´n del valor hispa´nico, corporativismo y elitismo basados del nacionalismo latinoamericano. En la de´cada de los treinta, la administracio´n de Ca´rdenas tomo´ en Me´xico medidas radicales de nacionalizacio´n de las propiedades extranjeras basada del nacionalismo econo´mico. A comienzo de las de´cadas de los sesenta, un nuevo feno´menon que se baso´ en el nacionalismo de recursos naturales ocurrio´ en Ame´rica Latina y el antinorteamericanismo se profundizaba y se desarrollaba al movimiento nacional de proteger los derechos de sus propios recursos naturales de cada pai´s latinoamericano, lo cual se exponi´a en su voluntad de expandir el poder de negociacio´n con Estados Unidos y otras potencias. Para tal fin, se busco´ una bondad entre los pai´ses interamericanos. De hecho, el Sistema Econo´mico Latinoamericano(8ELA) se inauguro´ en octubre de 1975 lo cual representaba un nuevo tipo de nacionalismo basado en la consolidacio´n y reacciones comu´mes entre los pai´ses en la regio´n. En conclusio´n, no se puede negar que la cultura poli´tica latinoamericana afectaba la formacio´n del nacionalismo latinoamericano directo o indirectamente.

文書館資料의 選擇論 : 政府 記錄의 保存을 中心으로

崔達鉉 경북대학교 교육대학원 1981 논문집 Vol.13 No.-

Modern archives function not only s a servant of the society performing its administrative demands and needs but also as a tool of science assisting discovery of the truth in historical studies. Therefore, every modern civilized countries have established archives appropriate to its own circumstances. The following proposals could be considered effective to facilitate the archival management of government records in Korea. First, nation-wide recognition of the role and activities of archives is essential to the effective management of government records with information or research value. In this respect, attitudes of policy makers in the central government would be most important to the development of national archives. Grigg Committee of 1952 in the United Kingdom is a good example for us. Second, professionally-trained staff produced by archival institutions must be in charge of archival management in various organizations including our Government Records Repository established in 1969. Third, all the important government records could be totally controlled only on such basis. Legislative and judicial documents should be preserved in the government's repository as well. Fourth, disposition of government records is to be done in accordance with a definite disposition schedule set up among the national archivist, administrators and subject specialists. This schedule is regularly reviewed and up-to-dated according to social changes. Fifth, although appraisal for the primary value of documents is made by administrative officers in cooperation with chiefs of operating agencies the national archivist has final responsibility of appraisal for the secondary value of documents. Last, an intermediate repository of documents for a temporary preservation before the final disposition would save important records from irrecoverable ruins. At any rate all the records could not be disposed without consent of the national archivist.
