비이상적인 전압 인버터 스위치 동작에 대한분석및 이를 이용한 스위치드-캐패시터 필터 설계 방법

이방원,박송배 대한전자공학회 1982 전자공학회지 Vol.19 No.6

본 논문에서는 V[S(voltage inverter switch)를 사용한 SCF(switched capacitor filler)에 있어서 VIS의 비이상적인 동작이 여파기 특성에 미치는 영향을 여파기를 구성하는 각 소자들의 변화로써 분석하는 방법을 제시하였다. 또 위의 결과를 VIS가 없는 SCF의 경우에 응용함으로써 대부분의 SC(switched cavacito.) 회로를 쌍일차(bilinear) 변환된 영역에서 그 등가각로를 쉽게 구할 수 있어 SCF의 분석이 용이하고, 높은동작 주파수를 갖는 SCF를 적은 수의 능동 소자로 구현할 수 있는 방법에 대해 기술하였다. 그리고 저역 통과 여파기와 대역 저지 여파기를 실험하여 그 결과가 이론치와 잘 일치함을 보였다. This paper proposes a method of analyzing the effect of non-ideal VIS (Voltage Inverter Switch) operation on SCF characteristics. In the special case of the VIS realized with only one switch, equivalent circuits of the elements proposed in [1]. [2]. [3] are obtained from the above results. Applying these results, SCF's operating at higher frequency than the conventional ones can be implemented and the equivalent circuits of most SC circuits can be obtained. Expermental results of a low-pass filter and a band-stop filter show good agreements with the theoretical characteristics.

A numerical study has been done on the evolution of particle size distribution in particle laden high temperature jet flows undergoing convection, diffusion, thermophoresis and coagulation. The dynamic behavior of these particles have been modelled by approximating the particle size distribution by a lognormal function throughout the process and the moments of the particle size distribution have been used to solve the general dynamic equation. The size distributions of spherical particles in the radial and axial direction have been obtained including the effect of buoyancy. Of particular interests are the variations of geometric mean diameter, number concentration and polydispersity. Results show that buoyancy significantly alters the size distribution in both axial and radial direction. One dimensional analysis for non-spherical particles has also been done and the results have been compared with the existing experimental data.

일제전기(1910~1931) 조선총독부의 사회사업과 그 특성

이방원,이방현 서울역사편찬원 2014 서울과 역사 Vol.- No.88

The social work programs that had been led by Government- General during the former part(1910~1931) of Japanese colonial rule can be characterized as follows : 1) It had the dual nature that contained the meanings of the control and benefits of civilized country via the hygiene program that was led by the police and army doctors ; 2) Institutes to house and reform orphans, the blind, the deaf and juvenile vagrants to be 'good citizens' were established ; and3) Temporal royal bounty that was used for social work programs aimed to support the job placement program and public facility that coincided with the colonial policy. Based on the aforementioned characteristics, it is reasonable to assume that the social work by Japanese Government-General of Korea in the former part of Japanese colonial rule was implemented not for the needs of social welfare clients, but for the policy and necessity of colonial government. 본 연구의 목적은 일제전기 조선총독부가 서울을 중심으로 실시하였던 사회사업을 정리하고 그 특성을 살펴보는데 있다. 이를 위해 해당시기 간행되었던 『조선총독부관보』, 『조선사회사업요람』, 『경성부사회사업요람』 등의 정부 간행지와 『조선급만주』, 『조선』 등의 일본어잡지 그리고 『매일신보』, 『조선일보』, 『동아일보』 등의 신문자료를 문헌고찰하였다. 일제전기 조선총독부가 주도한 사회사업에서 1) 경찰과 군의에 의해 주도된 위생사업이 내포한 문명국가의 통제와 시혜라는 이중적 성격, 2) 고아, 맹아자, 부랑아와 같은 사회패잔자를 선량한 신민으로 개조하기 위한 기관설립과 수용, 3) 주요 사회사업 자금인 임시은사금이 식민정책에 부합하는 수산사업과 공설사업 지원이라는 특성이 발견된다. 이상의 결과로부터 일제 전기 조선총독부의 사회사업은 사회복지 대상자의 욕구보다는 식민당국의 정책과 필요에 의해 실시되었다고 볼 수 있다.

세브란스 간호사의 독립운동: 1919년 독립운동을 중심으로

이방원 연세대학교 의학사연구소 2019 연세의사학 Vol.22 No.1

The purpose of this study was to reveal the names of nurses of Severance who endeavored for Korean independence under Japanese rule and to identify the efforts of each individual. In this study, “nurses of Severance” refers to the probationer nurses, student nurses, and graduate nurses who studied at Severance Nursing School, including those nurses who could not graduate nursing school. The nurses of Severance began their independence movement when they cured soldiers wounded in the protest against the dissolution of the Korean Army who had been brought to Severance Hospital in 1907. In 1919, the March 1st Movement provoked their action again. We could identify the names of 11 nurses of Severance who endeavored for Korean independence. They are Lee A-Joo, Tak Myong-Sook, Lee Jeong-Sook, Park Ok-Shin, Yoon Jin-Soo, Noh Soon-Kyong, Park Deok-Hye, Lee Doh-Shin, Kim Hyo-Soon, Jang Yoon-Hee, and Jeong Jong-Myong. While Korea was under Japanese rule, Lee A-Joo and Tak Myong-Sook participated in the March 1st Mansei demonstration. Tak Myong-Sook also aided Kang Woo-Gyu, who fired a shot at Korean governor Saito in September 1919 before taking refuge. Noh Soon-Kyong, Park Deok-Hye, Lee Doh-Shin, and Kim Hyo-Soon participated in the Hoon-Jeong Dong Jong-Myo (Ancestral Shrine) Mansei demonstration. Jeong Jong-Myong protected fighters for independence who were disguised as patients at Severance Hospital and delivered documents related to the independence movement. Jang Yoon-Hee distributed Fighter for Independence. After the March 1st Movement, Lee Jeong-Sook, Park Ok-Shin, and Yoon Jin-Soo organized and participated in women’s independence societies such as the Hyeolseong Corps Women’s Association, the Korean Patriotic Women’s Society, and the Korean Red Cross. They recruited members of women’s independence societies, organized and extended branches, aided prisoners and their families, and collected funds for the independence movement. Although we can’t identify all their names, many other nurses of Severance also endeavored for Korean independence. One hundred years ago, nurse was one of the most highly educated jobs. Nurses of Severance actively endeavored for Korean independence using their expertise in acquisition and networks of friends during a national crisis situation, Japanese colonial rule. They retained their patriotic spirit for Korean independence throughout the process of arrest, interrogation, and trial. They endured a severe inquisition and poor circumstances in prison. After getting out of prison, they struggled consistently for national development and independence by engaging women’s educational and social activities.

未履行契約會計의 接近方法 : 資源槪念變更 接近方法을 중심으로

There are three different levels of modification of present accounting practices. The most fundamental modification would be to change the concept of resources. The second level of modification would be to keep the resource concept as it is traditionally understand, but to modify the concept of control. The third level of modification would be to retain the present resource concept as well as the control criteria, but to change the recognition criteria. There are at least three important elements in the asset definition of the SFAC. No.3 : ① a current or past transaction, ② expected future economic benefits or service potentials, and ③ rights to those expected benefits or potentials. Expanded transaction concept - a transaction is basically an exchange of values (economic benefits) and it is suggested that entering into an executory contact constitutes an accounting transaction.

The influence of hypothermia on the contractile response to norepinephrine in the isolated rat vas deferens was studied. The results were as follows : The influence of hypothermia on the contractile response to norepinephrine in the isolated rat vas deferens was studied. The results were as fellows : 1 . The contractile potency of norepinephrine in the isolated rat vas deferens was increased by lowering the organ bath temperature from 97 "C to 20 ℃ as mensured by EDso ratio. 2 . In low temperature(20℃) -treated preparations, pAs value, on affiRity index of receptorfor antagonist, was higher than that of control (37℃) group. 3 . Potentiating effect of cocaine was not changed at both temperature.From the above results, it is auggested that potentiation of norepinephrine in rat vaa deferengby hypothermia is possibly due to the increase in receptor affinity rather than inhibition ofamino pump. (Key words : hypothermina, α-adrenoceptor Vas deferens)
