김영운,정기원,Kim, Young-Woon,Chong, Ki-Won 한국정보처리학회 2007 정보처리학회논문지D Vol.14 No.1

IT 투자는 기업의 일반적인 투자와는 달리 직접적인 효과를 계량화하기 어려운 부분이 있기 때문에 경영자가 IT에 투자 의사결정을 내리기가 어렵다. IT 투자에 대한 타당성을 입증하기 위해서는 정보 제공자와 수혜자가 공감할 수 있는 객관적인 평가 체제의 수립과 신규 IT 투자에 대한 경제적 효과에 대한 계량적인 척도 및 측정 방법을 포함한 정량적인 분석 틀을 제시하는 것이 필요하다. 따라서 본 논문은 기존의 투자에 대한 타당성을 입증하기 위한 모델들의 장점을 수용하고 단점을 보완한 IT 투자와 그 투자에서 얻어지는 IT 효과를 분석하여 투자타당성을 입증할 수 있는 IT ROI 방법론을 개발하여 5개 업종 21개 기업에 적응한 결과를 반영한 IT ROI 시스템을 구축하였다. 이 시스템에 의해 정보시스템이 기업의 활동에 기여하는 효과에 대한 객관적인 타당성을 확보하여 IT 투자 의사결정을 도와주고, IT 투자를 보다 합리적으로 결정할 수 있어 효율적인 IT 투자가 이루어질 수 있는 체계를 제시한다. When it tomes to IT investment, it's a challenge for the management to make the right decision. Unlike investment in other business area, it's hard to measure direct cost vs. effect in IT business. To validate the investment in IT, it is required to establish objective assessment system that both provider and beneficiary of information can accept, and it is also required to suggest an assessment tool of fixed quantity that includes measuring standards and method for the economic effect of new investment. This study, therefore, has developed IT ROI Methodology that can prove investment validity by accepting the strong points of the existing models while complementing their weak points and by analyzing IT Investment and IT Efforts. It also has built an IT ROI System that reflects the methodology which is applied to 21 companies of 5 business categories. This system is designed to provide effective and objective decision-making tool for IT investment by proving what positive impacts IT could have on business activities.

최근 급진적으로 반도체 기술이 발전함에 따라 집적회로(VLSI)의 집적도가 향상되고 있으며, 이동통신 및 멀티미디어의 발달로 많은 양의 데이터를 고속으로 처리하기 위한 대규모 프로세서들이 개발되고 있다. 전가산기는 디지털 프로세서와 마이크로프로세서에 있어 매우 중요한 요소이다. 따라서 전가산기 설계 시 전력소비와 스피드의 개선은 중요한 요소이다. 본 논문에서는 일반적인 Ratioed 로직과 패스 트랜지스터 로직을 이용하여 새로운 구조의 전가산기를 제안하였다. 제안된 전가산기는 일반적인 CMOS, TGA, 14T에 비해 좋은 성능을 나타내었다. 제안된 회로는 지연시간의 경우 기존회로의 평균값에 비해 13%우수하였고 PDP(Power Delay Product)비율은 약 9% 정도 우수한 특성을 보이고 있다. 실측 회로의 크기 평가를 위해 0.18um CMOS공정으로 레이아웃을 하고 HSPICE를 이용하여 시뮬레이션 하였다. With the recent development of portable system such as mobile communication and multimedia. Full adders are important components in applications such as digital signal processors and microprocessors. Thus It is important to improve the power dissipation and operating speed for designing a full adder. We propose a new adder with modified version of conventional Ratioed logic and Pass Transistor logic. The proposed adder has the advantages over the conventional CMOS, TGA, 14T logic. The delay time is improved by 13% comparing to the average value and PDP(Power Delay Product) is improved by 9% comparing to the average value. Layouts have been carried out using a 0.18um CMOS design rule for evaluation purposes. The physical design has been evaluated using HSPICE.

Cough syncope is characterized by the loss of consciousness occurring after vigorous coughings. There are approximately 90 reported cases of cough syncope within the medical literature. Most cases involving middle aged, overweight and chronic bronchitic male smokers. Although many studies have been published in the medical literature, the mechanism and pathophysiology for cough syncope has not been well established. Cough syncope is treated by correcting the underlying cause when identified, or by avoiding conditions that may cause the cough syncope. In addition, cough suppression modalities can also be used. We herein report 3 cases of cough syncope presenting in lung cancer patients.

1913년 高宗 誕辰日 祝賀宴 樂舞 연구 : 藏書閣 所藏 『朝鮮雅樂』에 基하여

김영운(Kim Young-Woon) 한국학중앙연구원 2007 장서각 Vol.0 No.18

이 연구는 한국학중앙연구원 장서각(藏書閣)이 소장하고 있는 일제강점기 자료 인 『조선아악(朝鮮雅樂)』에 기록된 1913년 고종(高宗) 탄신일 축하연에서 연행된 악무에 관한 연구이다. 1913년 9월 8일, 덕수궁(德壽宮) 돈덕전(惇德殿)에서 거행 된 이 연향은 1912년 고종의 회갑(回甲)을 축하하기 위하여 마련되었으나, 사정으로 인하여 한 해 늦추어 거행된 것으로 보인다. 1910년의 을사늑약(乙巳勒約)으로 이미 국권(國權)을 상실한 시기에 열린 이 연향은 여러 가지 측면에서 조선시대나 대한제국 시기의 국연(國宴)과 차이를 보인다. 이 글에서는 국권상실기에 마련된 비교적 큰 규모의 왕실 연향인 고종 탄신일 축하연의 형식과 내용을 살펴보고, 이 축하연에서 연행된 음악과 무용 및 그 담당층에 관하여 고찰한 다음 조선시대와 대한제국기의 궁중연향을 비교하여 그 차이점 을 밝혀 보았다 그 결과 1913년 고종 탄신일 축하연의 형식과 내용은 조선시대나 대한제국기의 국가적인 연향인 진연 · 진찬 등과는 많은 차이가 있다. 의례 자체가 전혀 달라졌기 때문에 이들 행사에서 연행된 음악과 무용의 내용도 크게 달라졌다. 이처럼 왕실의 의례가 변화를 보이게 된 가장 큰 이유는 이미 국권을 상실한 이후이기 때문에 고종에게 한 국가의 군주에 해당하는 예우를 할 수 없었기 때문이기도 하겠으나, 의례의 형식과 내용이 큰 변화를 보이는 또 하나의 요인은 왕실 의례의 서구화와도 밀접한 관련이 있다 이 축하연의 준비과정에서부터 전통적인 진연이나 진찬과 다른 관점에서 접근하였으며, 외빈이 참석하는 잔치는 서양식 연회로 구성하였다. 따라서 장소와 음식이 모두 서양식으로 준비되었고, 연회의 주악도 서양음악이었다. 대부분의 전통 악무는 '여흥(除興)'의 위치로 밀려나게 된 점은 당시 의 정치-사회적 변화를 반영한 것으로 이해된다. 『조선아악』의 관련기록을 통하여 당시 국가적으로 중요한 행사에서 비록 여흥의 절차에서이지만, 다양한 민간음악이 공연되었다는 사실을 통하여 이 시기 문화계의 인식 변화를 엿볼 수 있다. This paper is a study of music and dance performed at the royal birthday celebration banquet for King Gojong (Gojong Tansinyeon) in 1913 based on written records included in 『Joseon A-ak(朝鮮雅樂)』, a file of various documents compiled during the Japanese colonial period and currently housed in Jangseogak, at the Academy of Korean Studies. The banquet was given on September 8, 1913 at Dandeak-jean(惇德殿), Deoksugung Palace(德壽宮). Though the 60th birthday anniversary of King Gojong reached in 1912, celebration event was delayed by one year for some reasons and conducted in 1913. The banquet was held when the Josean dynasty had lost its sovereignty after the Japan-Korea annexation treaty called 'Eulsal Neugyak' (a coerced treaty of Korea's annexation to Japan) in 1910 and therefore revealed much difference in many aspects from the royal banquets held during the period of Joseon or the Korean Empire. In this paper, formalities and contents of the large-scale royal celebration banquet for King Gojong's 60th birthday anniversary during the period of Japanese rule in Korea was dealt with. The repertoire of music and dance and the performers for this banquet were identified. Finally, comparative study with the royal banquets conducted during the period of Jaseon or the Korean Empire was carried out to find differences. The results show much difference in formalities and contents between the royal celebration banquet for King Gojong's 60th birthday and a number of Jinjeon or Jinchan (national banquet of the Joseon dynasty or the Korean Empire). It can be concluded that complete reformation of royal banquets from earlier period naturally linked to great change in repertoire of music and dance performed for a banquet. The most primary background of significant change in royal ritual can be attributed to the fact that the royal influence of King Gojong was greatly dwindled after he had lost his sovereignty and so it was not possible to offer King Gojoing the royal privileges earlier granted to him as the king of a country. The other major reason is closely related to westernization of royal rituals. From the initial organizing processes of the banquet, totally different perspectives were applied from those used for preparing Jinyeon and Jinchan. Feasts for foreign guests were held in western style. Accordingly, banquet hall and dishes were arranged in western style. So was for music and dance. It was from such social and political changes at that time that most of traditional music and dance was ousted into the position of entertainment. The related records compiled in 『Joseon A-ak』 also reveals that diverse kinds of Minganeumak (non-royal music) were performed, though as entertainment, for the events with national significance. Through this fact, it can be inferred that there might have been some changing perspective on Minganeumak (non-royal music) among the people of culture society.
