윤이상의 <고풍의상>: 박, 박자 및 리듬적 특징 연구

주윤영 ( Yun Young Joo ) 세계음악학회 2012 음악과 문화 Vol.27 No.-

Yun`s early art song <Traditional Attire> successfully represents the rhythmic characteristics of Korean traditional music, which is the coexistence of duple and triple meter in musical time. However, it has never been studied in depth. Thus, this paper will discuss how Yun brought out the rhythmic characteristics of Korean traditional music, not depending on any particular changddan (rhythmic patterns of Korean traditional music), and rhythmic features of the Korean text within the musical texture. In the course of the study, "Si-Jo," one of the three genres of traditional Korean classical art song, will be mentioned, and Pyongsijo <Dong-chang-i> will be examined to provide background discussion.

우리 나라 기업의 현금흐름특성과 현금흐름경영

윤주석,여정구 목원대학교 사회과학연구소 1999 社會科學硏究 Vol.- No.3

본연구에서는 1994년부터 작성되기 시작한 현금흐름표를 통해서 우리 나라 기업의 현금흐름특성을 살펴보고자 하였다. 1994년부터 1998년까지의 현금흐름표를 통한 분석결과 우리 나라 기업이 영업활동을 통한 현금흐름창출능력이 부족해서 외부자금에 의존하는 이른바 우리 나라의 고직적인 병폐라 할 수 있는 차입경영의 실상이 극명하게 드러나고 있다. 그러나 IMF사태를 겪고 난 다음 연도인 1998년의 현금흐름특성을 보면 영업활동을 통한 현금창출능력을 개선시키면서 부채를 축소시키는 노력을 하는 결과를 발견할 수 있어 우리 나라 기업도 선진국처럼 현금흐름경영의 방향으로 나아가고 있음을 알 수 있다.

In this research, the early-age movements of joint at JPCP(Jointed Plain Concrete Pavement) were measured by field tests. The field tests were carried out for 5 days just after concrete placement, for 1 day after 52 and 72 days on Chung-Ang Expressway construction site in Dan-Yang on the 28th and 29th of May 2001. The joint movements were measured by demec gauge and clip gauge. The results of regression analysis for the data measured during early 5 days showed that the joints of No.4, No.5, No.6, No.10, No.13, and No.15 could be considered as a moving joint. From data analysis on July 20, the joints of No.2, No.9, and No.10 showed the significant correlations from the minus value of coefficient of regression. As a result of regression data on August 8, joint movements occurred at all joints. Joint freezing and closure could be judged from the regression analysis using joint opening and total temperature measured at field tests.

라텍스 개질 콘크리트의 건조수축특성

Drying shrinkage cracking which may be caused by the relatively large specific surface is a matter of grave concern for latex modified concrete(LMC) overlay and rapid-setting cement latex modified concrete(RSLMC) overlay. Therefore, the purpose of this dissertation was to study the drying shrinkage properties of LMC and RSLMC with the main experimental variables such as cement types(ordinary portland cement, rapid setting cement), latex contents(0, 5, 10, 15, 20%), W-C ratios, and curing days at a same controlled environment of 60% of relative humidity and 20℃ of temperature. Test results revealed that the drying shrinkage of latex modified concrete(LMC), rapid-setting cement latex modified concrete(RSLMC) was considerably lower than that of ordinary portland cement concrete(OPC), rapid-setting cement concrete(RSC), respectively. This may be attributed to the interlocking of hydrated cement and aggregates by a film of latex particles, water retention due to hydrophobic and colloidal properties of the latexes, resulting in reduced water evaporation.

요인 실험분석에 의한 SB 라텍스 개질 콘크리트의 강도예측

윤경구,이주형,홍창우 江原大學校 産業技術硏究所 2001 産業技術硏究 Vol.21 No.B

The purpose of this study was to provide the evaluation and prediction of strengths of SB latex modified concrete(LMC) using a statistical method and factorial experimental design method. The main experimental variables were as follows; W/C(4 levels ; 31, 33, 35, 42%), S/a(2 levels ; 55, 58%) and L/C(2 levels ; 5, 15%). The compressive strength and flexural strength of LMC were selected as a factor of response. The statistical method was carried out to analyze the results, together with factorial experimental design method and response surface method. The analysis showed that if L/C had been 15%, W/C appeared to be around 33% to achieve the design strength of 350kgf/cm2. In this case, the flexural strength and the slump came to around 68kgf/cm2 and 18cm, respectively. Eventhough the L/C varied, the design strength and W/C could be predictable together with slump value and flexural strength. As a result of series of experiments in this study, W/C and L/C were proved to be the main factors influencing on the compressive and flexural strength of LMC. Both of strength and slump values could be predictable from the mixing proportion of LMC.

라텍스 개질 콘크리트의 강도발현 및 내구특성

본 연구는 라텍스 혼입률이 5%, 10%, 15%, 20%로 변화할 때 라텍스 개질 콘크리트의 내구 특성을 평가하는데 있다. 라텍스를 콘크리트에 혼입한 라텍스 개질 콘크리트는 보통 콘크리트의 색상과 성형성, 작업성를 갖으며, 약 20%~35%의 단위수향이 감소된다. 그리고 양생후, 콘크리트는 시멘트수화물과 라텍스 입자의 필름막에 의해 연결된 골재로 구성된다. 일반적으로 라텍스 양이 증가하면 콘크리트의 휨강도는 증가하는데, 이것은 라텍스가 시멘트 수화물과 골재사이의 점착력을 증가시키기 때문으로 판단된다. 라텍스 개질 콘크리트와 보통콘크리트와의 상대투수성을 측정하기 위하여 염소이온투과시험법을 사용하였다. 그 결과 라텍스 개질 콘크리트의 투수성은 보통콘크리트의 투수성보다 매우 낮음을 알 수 있었다. 이것은 라텍스가 미세공극을 충진하고 라텍스 입자의 필름막에 의해 골재와 시멘트수화물이 연결 때문이다. 또한 라텍스가 공극주위로 필름막을 형성하기 때문에 공기량이 투수성에 영향을 미치지 못한다는 것을 알 수 있었다. 보통콘크리트에서는 동결융해저항성을 증가시키기 위해 공기연행제를 필요로 하지만, 라텍스 개질 콘크리트에서는 적절한 양생이 이루어지면 추가적인 공기연행제는 요구되지 않는다. 또한 라텍스 혼입률이 증가함에 따라 추가적인 동결융해저항성의 증가는 나타나지 않았다. This study focused on the investigation of strength development and durability of latex modified concrete(LMC) as the latex content variated such as 5%, 10%, 15%, and 20%. When latex was added to concrete, the workability of LMC was quietly increased, compared to that of conventional concrete. This resulted in the decrease of the required water as 20% to 35% in order to obtain a same slump. In general, increasing the amount of latex decreased compressive strength a little but increased flexural strength quite a lot. This might be due to interconnection by a film of latex particles between hydrated cement and aggregates. This, also, might attribute to bonding between the hydrated cement and aggregates. The rapid chloride permeability test was used to evaluate the relative permeability of latex-modified concretes and conventional concretes. The results showed that the permeability of latex-modified concretes was considerably lower than that of conventional concretes tested, which might be due to the latex filled in voids and interconnections of hydrated cement and aggregates by a film of latex particles. Because of latex formed film surrounding the air void, air contents and voids does not effect to the permeability of latex modified concrete.

The purpose of this project is to show the design of the outdoor area of the apartment being divided into main and necessary spaces, and then being divided into smaller spaces ideally based on the first few. Through this project, we were able to see an example of how the apartment community functioned after the smaller spaces were placed. After seeing this example, we created a more specific and subjective checklist. In conclusion, the outdoor space of the multi-family housing was first divided into five spaces including a living room, a space where physical activity is possible, a space where people socialize, one for economic purposes and apartment security, and space for entertainment. Afterwards, the five spaces were broken down into several smaller areas into a total of 41 smaller spaces. A checklist was made from the five main spaces being broken down to a more specifically detailed 41 spaces. This checklist, which is pointed out while handling the contract, is a helpful key in the foundation in order to satisfy future residents of the apartment.
