철근콘크리트 구조물은 과도한 하중과 유지관리의 소홀 등 여러 가지 이유로 보수${\cdot}$보강을 필요로 하는 경우가 많다. 이에 대해 국내에서는 철근콘크리트구조체의 보강방법으로 강판, 탄소섬유쉬트, 탄소섬유판을 사용하고 있다. 그러나 이들 보강재료의 성능에 대하여 신뢰할 만한 연구 결과가 아직까지 충분치 않은 실정이다. 본 연구는 보강재의 종류, 균열폭, 하중의 재하상태를 변수로 보강된 철근콘크리트보의 거동을 규명하고자 하였다. 보수시험체의 경우 기준시험체와 내력과 연성은 비슷한 거동을 나타냈으나 파괴형상은 인장부위 콘크리트의 탈락과 지압파괴가 발생하였다. 보강시험체의 경우, 보강의 효과는 뚜렷이 나타났으나 보강재의 물성을 100% 발휘하지는 못하였다. 탄소섬유쉬트의 경우 접착제의 성능이 완벽하지 않아 최대 내격시의 변형률이 파단시의 변형률과 비교하여 66%정도로 나타났다. 또한 보강시의 균열폭과 하중의 유${\cdot}$무는 부재의 내력과 거동에 영향을 거의 미치지 않는 것으로 나타났다. In recent years, strengthening by steel plate, carbon fiber sheets, and carbon fiber laminate is spotlighted in order to repair and rehabilitation of R/C structures. In this study, 3 methods of rehabilitation technique were analyzed from the test results. Test parameters were the width of cracks, the method of repair and rehabilitation, the magnitude of pre-load. Deflections, failure loads, strains of reinforcing bar, strains of carbon fiber sheet, carbon fiber laminate and steel plate were measured during the tests. The primary purpose of this research was to analyze the failure mode and structural behavior of strengthened RC beams with/without superimposed pre-load. Test results should that no significant difference was observed between with pre-loaded specimens and no-loaded specimens during rehabilitation.

본 실험은 지금까지 우리나라에서 수행 되어온 기존, 건축 토목관계 실험의 수준을 한차원 높히는데 크게 기여하리라 생각된다. Hydraulic Jack을ㄹ 이용한 1 방향 실험과는 비교할 수 없을 정도로 자동화, 기계화를 이루었으며, 실험에 사용된 Actuator는 미국의 MTS사 제품으로 빠른 속도 (2Hz에서 최대 +/-7.5cm Stroke)로 움직이는 반복 주기 하중을 컴퓨터가 제어하고 Data를 자동적으로 컴퓨터에 기록하므로 구조물의 동적특성까지를 규명하는데 필수적인 장비이다. 또한 Shaking table은 실제로 발생하는 지진파를 그대로 입력시켜 구조물에 대한 내진 성능을 완벽하게 측정할 수 있다. 특히 구조설계자들 사이에도 논란이 되고 있는 우리나라 내진규준의 R factor(반응수정계수)를 정하는데 매우 유효한 역할을 하리라 기대된다.

문학에서 영화로의 네오리얼리즘 루키노 비스콘티의 『흔들리는 대지La Terra Trema』

정란기 ( Lan Ki Jung ) 한국이탈리아어문학회 2009 이탈리아어문학 Vol.26 No.-

Comparare nell`opera di Luchino Visconti e neorealismo dalla letteratura al cinema, significa a capire sua ideologia del campo d`arte. Anche un uomo nobile che ha attraversato la storia d`Italia e d`Europa sapendone cogliere i mutamenti sociali, politiche, i ideologici, senza farsi a una contemplazione del passato, ma cercando ogni volta di rimettere in discussione della realta, di evidenziare le contraddizioni e gli aspetti negativi. La conoscenza dei romanzi di Giovanni Verga ha offerto a lui la nuova tema del progetto, la Terra Trema che usci nel 1948 come prima parte di un trittico sulle condizioni di vita dei lavoratori ed ebbe poi una vita stentata sugli schermi in un`edizione scorciata e deturpa, Vsiconti ispirarsi al grande romanzo verista ottocentesco, aggiornando sul tema dello sfruttamento dei pescatori costretti a subire le angherie dei grossisti di pesce. C`era una ricerca formale che superava gli elementi stessi della storia, il contenuto politico dell`opera; e l`esperienza teatrale, il lavoro con gli attori, la ricerca di un superamento del neorealismo, fornivano a Visconti l`estro per un discorso del tutto personlae, in cui non e difficile rintracciare quei motivi della sua arte che ritroveremo in altri contesti filmici. L`arte di Visconti pare seguire un progetto rigoroso, la traccia di un`interpretazione non superficiale della realta, di una lettura critica dei fatti, delle situazione, dei personaggi, dell`ambiente storico. Anche la scelta di certi moduli espressivi debitori piu della grande teatrale, figurativa e musicale dell`800, che non dell`900. Di qui infine il suo sogno originale, inconfondibile nel tratteggiare gli ambienti entro i quali far agire i personaggi, di costruire la scena in cui il dramma o la tragedia devevano esplodere. In questo senso, l`opera complessiva di Luchivo visconti, vista in prospettiva storica, rimane tra le piu importanti e valide nella storia del cinema e dellla letteratura e del teatro italiani. L`uso di Giovanni Verga, I Malavoglia come il sorgente della letteratura, La Terra Trema risulta nel testo che ha un impronto definitivo del orginale. Allo stesso tempo, il romanzo di Verga e stata usato come una media per avanzare il suo esperimento d`artista. Per venire alla concluzione le opere di Luchino Visconti, un direttore che e stato influenzato e formato il film non solo in Italia e in Europa, e scelto adeguamente se uno vuole esaminare il ruolo che la letteratura puo produrre il film. Le opere di Visconti sono appropriato non solo per la tendenza del direttore a incorporare le opere della leterattura lavora dentro suoi film. Fra del anno 1930 e la meta del anno 1970, Visconti lavora nel campo cinematografico, sua influenza puo dare sicuramente al sviluppo del neorealismo. La terra trema e un film significativo a lui, possono esaminare ai altri per la valutazione del film. La combinazione dei elementi dal testo originale, le opinione della regista, l`utilizzazione d`atrezzo cinematografico liberamente della vista della regista, maneggiare della macchina da presa, suono, montaggio, tutti combinazioi per creare e produrre le opere finale che puo` essere giocando. Questo e un prodotto sucesso per ideologico, neorealismo, a scopo di riflessione della societa reale.

Object modeling has been considered as an efficient technique for eliciting user requirements and communicating between developers and customers. But model itself is not easy to understand what result will be after coding and whether it will be meet with the requirements of customers. In this paper, we developed the environment for visualization of object model for validating with requirement at the early stage. Therefore, we defined correct and complete rules which can transform the object model, the deliverables of Shlaer/Mellor''s method, into a formal specification language of VDM(Vienna Development Methods) with a mathematical basis. This basis provides the means of providing that a specification is realizable and proving properties of a system. Therefore, the completeness, preciseness of object model can be verified by proving the transformed VDM specification and prototyping by constructing a visualization supporting environment.

Background/Aims: With the enormous increase in the amount of data, the concept of big data has emerged and this allows us to gain new insights and appreciate its value. However, analysis related to gastrointestinal diseases in the viewpoint of the big data has not been performed yet in Korea. This study analyzed the data of the blog’s visitors as a set of big data to investigate questions they did not mention in the clinical situation. Methods: We analyzed the blog of a professor whose subspecialty is gastroenterology at Gangnam Severance Hospital. We assessed the changes in the number of visitors, access path of visitors, and the queries from January 2011 to December2013.Results: A total of 50,084 visitors gained accessed to the blog. An average of 1,535.3 people visited the blog per month and 49.5 people per day. The number of visitors and the cumulative number of registered posts showed a positive correlation. The most utilized access path of visitors to the website was blog.iseverance.com (42.2%), followed by Google (32.8%) and Daum (6.6%). The most searched term by the visitors in the blog was intestinal metaplasia (16.6%), followed by dizziness(8.3%) and gastric submucosal tumor (7.0%).Conclusions: Personal blog can function as a communication route for patients with digestive diseases. The most frequently searched word necessitating explanation and education was ‘intestinal metaplasia’. Identifying and analyzing even unstructured data as a set of big data is expected to provide meaningful information. (Korean J Gastroenterol 2014;63:361-365)

This thesis is about Korean christian women’s movements in the first decade of the Japanese rule. In the beginning, the Japanese position on the women's issue was to emphasize the traditional role of submissive women that would be supportive their colonial rule. The steps taken by some korean christian women in this period, however, were quite different from the Japanese views, linked a modern theory of women's role and status. They focused attention on the gender equality at home and outside, and evolved women’s movements on this lines. Those who led the movements were bible women, lay christian women and teachers of christian women's schools. Bible women gained entry to households to preach the gospels and to show new ways of life for women at home. Their activity acted as a stimulus and encouraged a number of women aware of the questions of women and nation. Lay christian women also participated in the movements which sought modify ng gender relations, teaching women and establishing women's organizations. And teachers of christian women’s schools worked for teaching young girls at private seminaries, bring their charge to Christ and helping for anti-Japanese secret societies. All these movements proved very important bases for the following anti-colonial struggles led by women. By the 1920s, thereby, women’s activities began to emerge in other areas as well. While christian women's movements in the 1910s found a voice, mainly, around churches, they developed and expanded their activities through various women's organizations in the 1920s. There were also significant changes in the christian women's movements in this period. Since there were increasingly a number of christian women who were college-educated, it was they who led the women’s movements.

The Chung-Lim religion succeed to DongHak. It had a peculiarity of the people religion under the Japanese Colonialism. It had a revolutionary ideas. And the ideas gave hope to the people under the Japanese Colonialism. But Because of many restrictions, the internal acts tried to give inspiration of the national consciousness in mission level only. On the other hand, In Manchuria there was a power of Chung-Lim religion which tumbled to pro-Japanese religious organization, but another power had a standpoint of nationalism too . We can see the positive attitude about nationalism in the latter case. Actually, it was a secret organization. That means it's very difficult to find even outline of the Chung-Lim religion. Even a part of the facts are not revealed to us according to the arrestment of them by Japanese goverment. But who can't believe all the states of them under the sword. It isn't easy to grasp general outline of the secret organization in mansuria than in domestic area. If it could be a qualified popular religion for the nation, It has to be dear not only about personal information of believers but also the idea of them. We don't have enough information about it that means we can't sure if it was national movement or not. Through the continuous study, I believe we can get the whole figure of the Chung-Lim religion. As we studied about the flow of the Chung-Lim religion, there's a difference between the Chung-Lim religion and National Movement Organization which fought for the national independence. Accordingly, both quantitative and qualitative study can give us more sure understanding about the Chung-Lim religion in the national movement history.
