변환된 자기회귀이동평균 모형에서의 예측구간추정

조혜민,오승언,여인권,Cho, Hye-Min,Oh, Sung-Un,Yeo, In-Kwon 한국통계학회 2007 응용통계연구 Vol.20 No.3

시계열자료를 분석하는데 있어 중요한 목적 중에 하나가 미래값에 대한 예측이다. 일반적으로 자기회귀이동평균모형에서는 백색잡음이 정규분포를 따른다는 가정 하에서 모수의 추론과 예측 및 예측구간의 추정이 이루어지고 있다. 그러나 자료가 이러한 가정을 만족하지 않는 경우, 자료를 가정에 맞게 변환시킨 후 분석하는 방법을 생각해 볼 수 있다. 이 논문에서는 변환된 자료를 분석하여 얻은 결과를 이용하여 본래의 척도에서의 미래값에 대한 예측구간을 추정하는 문제에 대해 알아본다. 제안하는 방법에서는 먼저 적절한 변환을 이용하여 자료를 정규가정을 만족하도록 변환시키고 변환된 자료를 이용하여 미래값에 대한 예측구간을 추정한 후, 역변환을 이용하여 예측구간을 추정한다. 이 논문에서는 시계열분석에서 모델링이 상대적으로 어려운 왜도의 문제를 해결하기 위해 Yeo-Johnson 변환을 중심으로 한 방법론을 소개한다. 모의실험 결과 제안된 방법에 의한 단측예측구간의 포함확률이 변환을 사용하지 않은 구간보다 명목수준에 가까운 것을 확인하였다. One of main aspects of time series analysis is to forecast future values of series based on values up to a given time. The prediction interval for future values is usually obtained under the normality assumption. When the assumption is seriously violated, a transformation of data may permit the valid use of the normal theory. We investigate the prediction problem for future values in the original scale when transformations are applied in ARMA models. In this paper, we introduce the methodology based on Yeo-Johnson transformation to solve the problem of skewed data whose modelling is relatively difficult in the analysis of time series. Simulation studies show that the coverage probabilities of proposed intervals are closer to the nominal level than those of usual intervals.

이상화 문학에 나타난 시적 상상력의 근원 연구

유신지 ( Yu Shin-ji ),여상임 ( Yeo Sang-im ) 한국문학언어학회(구 경북어문학회) 2017 어문론총 Vol.74 No.-

이상화문학에 대한 논의는 이상화 당대는 물론, 1960년대부터 지금까지 상당히 구체적으로 진행되었다. 주로 상징주의나 낭만주의와 같은 문예사조적인 경향이나 저항시인이라는 민족주의적인 관점에서 연구가 많이 진행되었다. 그러나 이러한 관점에서는 이상화 문학 전반에서 드러나는 동양적이고 전통적인 사유를 다 해명하는 데는 한계가 있었다. 이상화문학과 그의 사상의 근저에는 동학이나 천도교적인 사상의 근간을 이루는 내재적 초월의 사유가 자리하고 있다. 내재적 초월의 사유는 이상화 문학의 곳곳에서 다양한 모습으로 드러나고 있다. 본고에서는 이상화의 시적 상상력의 근원이 이러한 내재적 초월의 사유로 파악될 수 있다고 보고, 전통시학의 관점, 특히 기층철학을 토대로 이상화의 문학 텍스트를 분석해보고자 했다. 특히 이상화의 전기적 사실들을 살펴보면, 그의 사상과 사유가 형성되는 중요한 시기인 십대와 이십대 전반에 걸쳐서 천도교적인 색채가 짙은 인물들과 깊은 교류를 맺었고 그와 관련된 활동들을 했다는 것을 알 수 있다. 또한 그가 제시하는 문학론이나 시작품들에서도 그러한 사유들이 드러나는 것을 볼 수 있다. 이상화의 문학평론이나 시에서는 우리 고유의 민속 신앙인 샤머니즘과 이를 계승한 동학사상의 색채가 드러난다. 그의 시작품들에서도 특징적인 것이 ‘하늘’,‘신령’, ‘검’, ‘동굴’ 등과 같은 시어들이 빈번히 쓰이고 있는데, 이러한 시어들은 이상화 텍스트 전반에서 관찰되는 ‘내재적 초월’의 사유들을 드러내는 것으로 쓰이고 있는 것을 볼 수 있다. 이러한 양상은 기존의 논의에서 채 규명되지 못한 부분들로, 동양적이고 전통적인 사유의 지평 안에서만 비로소 설명이 되는 부분이기도 하다. 이러한 논의는 이상화가 1920년대 시단의 다양한 흐름 속에서도 그 시류에 휩쓸리지 않고, 우리의 자생적인 사상이라 할 수 있는 전통철학의 토대 위에 그 나름의 시세계를 구축하였음을 확인할 수 있게 해주며, 나아가 이상화 문학을 바라보는 새로운 해석의 지평을 넓혀볼 수 있다는 점에서 의의가 있다. Untill now, the study on Lee Sang-hwa’s literature has been done very widely. Most rearchess have been done in the point of view of symbolism, romanticism, or nationalism. But, through these views, we couldn't find the basic thoughts of his Literature. There are immanent transcendence in the origin of his Literature and his own ideas. Therefor, at this thesis, we found that the origin of poetic imagination in Lee Sang-hwa’s literature is based on the oriental and traditional thoughts. Especially, when we searched Lee Sang-hwa’s biography, we found that he was related to the people who had Chondo-kyo belief. Such thoughts appeared his literary theory or in his prototypes. His literary criticism and poetry reveal the color of Korean folk faith, Shamanism and Donghak's succession. In his poetry text, the words such as 'heaven', 'spirit', 'sword' and 'cave' are frequently used. And these words are used to reveal the aspects of 'Immanent transcendence' observed wholy. This aspect can not be clarified in the existing discourse and is only explained within the horizon of the traditional thoughts. This study enables us to confirm that Lee-Sanghwa has built his own poetry system on the basis of traditional philosophy which is not influenced by the currents in the various ideal flows of the 1920s. In addition, it has a significance in that it can broaden the horizon of the new interpretation in reading the Lee-Sanghwa’s literature.

주거공간의 LONG LIFE DESIGN에 관한 연구

여상진 慶星大學校 1996 論文集 Vol.17 No.4

Our residential space dose not exist as a space in its true meaning until it comes to possess its clear purpose of a space which is the most familiar to our human life and in which we stay longest, and so every furniture and ornament should appear unified in its harmonious way, holding its complementary relationship at the same time. Therefore, this study aims at suggesting the two necessary things for the long Life Design. First, we should prolong the life-span of furniture through developing products which we can replace its parts or surfaces so as to change our home furniture has been designed independent to our residential space each other, irrespective of the character of our residential space as well as its user's personality and individual taste. Second, we should set up a movement for standardizing a similar kind of products from all the other furniture manufacture. For only through its standardization, we consumers con replace parts or surfaces of our furniture in our own way according to our tastes or desires even if it came from another manufacturer's, to say nothing of reducing the industry wastes which are concerned with our serious environmental problem.

AbstractThe object of 1994 York-Antwep Rules is to make the Rules clear without expansion in the area of general average and to bring the Rules up to date and to tackle certain contemporary problems, particularly those relating to environmental damage in the context of general average.For that purpose the paramount clause applying the concept of reasonableness to all subsidiary Rules is introduced.YAR regulate tug and tow situations that were different between countries, so uniformity of practice can be achieved.The enviromental issue is introduced and all environmental damage liabilities are excluded from general average but to allow the cost of environmental damage avoidance measure in certain restricted circumstances.YAR import the essence of the forms of Non-Separation Agreement previously in use.To make the adjustment fast, the duty to give notice to the average adjuster and tc supply evidence of general average is introduced in the Rule.But some improtant practice are not adopted.The Rule does not decide the internationally accepted practice of the currency of adjustment and rate of exchange.And the Rule does not accept the practice of the container transport. The contributory value of the cargo is the value at the time of discharge. But the container is opened at the destination, so it is more convenient for the container cargo to apply the value at the time of delivery.Those issues must be treated in the near future.

탈지대두박에서의 Isoflavone의 분리를 위한 흡착제의 조건

여경은,조성빈,김우정 한국산업식품공학회 2003 산업 식품공학 Vol.7 No.4

탈지대두박을 이용한 isoflavone의 분리 및 정제를 위한 최적 조건을 찾고자 absorption resin인 Amberlite XAD-1180를 사용하여 흡착제의 활성화용매의 농도, 흡착된 isoflavone의 용출용매의 농도, 용출용매의 양과 용출속도, 시료와 흡착제의 비율 그리고 수지에 미치는 pH와 ion의 영향을 조사하였다. 수지의 활성화와 용출에는 Amberlite XAD-1180의 경우 methanol 75%로 활성화시키기 ethanol 80%로 용출시키는 경우가 가장 높은 값을 보였으며, 이때 사용하는 absorption resin은 isoflavone 흡착을 위해 사용한 단백질제거 탈지대두박용액양의 약 0.5배로, ethatnol의 양은 단백질제거 탈지대두박용액 양의 4배를 사용하여 flow rate 12mL/min의 경우가 적절한 조건임이 밝혀져 흡착제 사용이 isoflavone 함량을 최고 2~3배까지 향상시키는 결과를 보였다. 이때 분리된 isoflavone의 순도는 최고 40%까지 얻을 수 있었다. pH와 ion의 영향에서는 pH는 5.0,NaCl은 0.25N 이하에서 isoflavone의 유출량이 높았다. Conditions for sorption and elution of isoflavone with using amberlite XAD-1180 were studied to separate Isoflavone from defatted soybean flour (DSF). Isoflavone analyzed were daidzin, genistin, glycitin, daidzein, genistein and glycitein by HPLC. The result showed that washing Amberlite XAD-1180 with 75% methanol and then elution of isoflavone with 80% ethanol resulted the highest amounts of isoflavone recovered from the absorption resin. The most proper eluent factor was 4(eluent/sample volume), the sample factor was about 2(the volum of sample/the weight of resin) ad flow rate 12 mL/min. The pH 5.0 and less than 0.25 N NaCl were found to be proper for seperation of isoflavone. The isoflavone contents after seperation with absorption resin were about 40% in dry weight basis.

신뢰성 이론에 의한 PSC박스거더교의 시공중 안전성 평가

여성욱,장일영,송재호 금오공과대학교 산업기술개발연구원 2000 産業技術開發硏究 Vol.16 No.-

Recently, the bridge structures are becoming longer and larger mainly due to the development in materials, the improvement in construction and the advance in structural analysis and design technique. So, construction of this type of bridges such as cable stayed bridge, suspension bridge and segmental PSC box girder bridge are increasing nowadays. Especially, the segmental PSC box girder bridges are widely constructed for medium and long span bridges. But it has been well known that structural failure probability during the construction, in general is higher than that during the service life due to lack of the empirical judgement, field data and standard process for the construction as well as due to high uncertainty involved in the evaluation of loads and strength of structures during construction. So in this study for the reliability based safety assessment of segmental PSC box girder bridges during construction, which are erected by Free Cantilever Methods, a set of linear strength limit state models are suggested for the box girder. The reliability of the structures using the proposed practical limit state model is evaluated by using Advanced First Order Second Moment method. Also the proposed models are applied to the safety assessment of a real bridge during construction stage in order to check their applicability in practice for the bridge assessment engineering. Finally, the important factors of construction stages are identified through the sensitivity analysis of the main random variables.

韓末 客舍建築의 消滅

여상진,심우갑 대한건축학회 2004 대한건축학회논문집 Vol.20 No.10

This study aims to clarify the disappearing process of Gaek-sa(客舍) in the end of Choson Dynasty Because Jeon-pae(殿牌) which is representing Loyal authority was enshrined in the Gaek-sa and at which a local governol performed a ceremony for the king After the King's Flight to Russian Legation, Jeon-pae was revised to Gual-pae(闕牌) which symbolizes the emperor And Gaek-sa was repaired and maintained during the Great Han Empire Period But Gaek-sa was occupied by Japanese troops during the Russo-Japanese War(1904-1905) especially in the north-western provinces of Korea And Gaek-sa was converted into a primary school or local court of law in the Protectorate Period(1904-1910) As this convert, the used parts of Gaek-sa were suppose to be only the wings which were detached from Main Hall(止廳) because Gual-pae was still enshrined in Main Hall The enshrinement of Gual-pae was stopped after November, 1909 The portrait of emperor which was enshrined in school and local government office had taken the place of Gual-pae since 1907 So the disappear of Gual-pae and Gaek-sa is tolerated Nevertheless Gual-pae was still enshrined at Geak-sa until Consolidation of Korea and Japanese(1910 8) With this, the Gaek-sa which symbolize the king of Chosun Dynasty came to disappear
