In order to provide the basic data required for an effective physical exercise program to get rid of obesity, women in their 20s to 50s who had never participated in a regular physical exercise were classified into GroupI, GroupII, and GroupIII consisting of 10 persons each with 25 to 30%,34 to 35%, and over 36% of body fat rate respectively, and then they were checked up with their maximum physical exercise intensity by using RAMP II protocol to analyze relations of physiological causes of change at the time of the maximum fat oxidation intensity for the three groups with the result of analysis as follows, 1.Maximum fat oxidation and fat -free weight(r=.396, p〈.03), oxygen uptake(r=.569, p〈.001) and ruts piratory exchange rate(r=.673, p〈.000) have notable co-relations one another. 2.At the time of the maximum fat oxidation intensity, oxygen uptake, heart rate, respiratory exchange rate, fat oxidation, and energy consumption among the 3 group have shown no notable statistical difference one another. 3.At the time of the maximum fat oxidation intensity, percentage in the maximum oxygen uptake value(% VO2max) shows a notable difference among the three groups. A post verification shows GroupIII has a notable difference from GroupI or GroupII(p〈.05) while there is no notable difference between GroupII and GroupI. In conclusion at the time of the maximum fat oxidation intensity, GroupIII(body fat rate of over 36%) shows a notably high relative intensity. Accordingly people of high body fat rate need the tensity of 60% VO2max in aerobic exercise to reduce their fat.

원내에서 5축 밀링기로 가공한 PMMA temporary crown의 다양한 임상적 활용

서상진,Suh, Sangjin 대한심미치과학회 2017 Journal of the Korean Academy of Esthetic Dentistr Vol.26 No.2

With the increasing popularity of dental CAD / CAM, the kinds of materials that can be used and the range that can be utilized are also increasing. One of the biggest advantages of a dental CADCAM is that you can make a final prosthesis with one visit, but in case of zirconia or a complex aesthetic prosthesis, it is often difficult to make it in one day. In this case, temporary PMMA material can be used to provide a temporary crown with aesthetic and functional properties to the patient and can be used as a test crown or template for the final prosthesis. And if you are with a 5-axis milling machine in a clinic, you can make a temporary crown precisely to a large extent in a short time. In this article, various applications and clinical cases of PMMA temporary crown in the clinic will be presented.

DQN 기반 TCP 혼잡제어 알고리즘의 성능평가

서상진,조유제 한국통신학회 2024 韓國通信學會論文誌 Vol.49 No.4

기존의 TCP 혼잡제어는 느린 혼잡 윈도우 (cwnd) 증가율로 인해 전송 대역폭이 매우 크거나, 채널의 특성이빈번하게 변화하는 환경에서 사용 가능한 대역폭을 충분히 활용하지 못하는 문제점이 있다. 이러한 문제를 개선하기 위해 기계학습을 적용한 적응형 TCP 혼잡제어에 관한 연구가 꾸준히 진행되고 있다. 본 논문에서는 강화학습의 일종인 Deep Q-Network (DQN)을 TCP 혼잡제어 알고리즘에 적용하여 성능을 개선한 DQN-based NewReno 와 DQN-based CUBIC을 소개하였다. 구현한 알고리즘들은 NS-3 시뮬레이터를 통해 성능 평가를 수행하였으며, 실험 결과를 통해 DQN-based CUBIC이 특히 기존 혼잡제어에 비해 높은 처리량을 보이고, 서로 다른 혼잡제어프로토콜 간의 공평성과 round trip time (RTT) 공평성 모두 향상됨을 확인하였다. The existing TCP congestion control suffers from the problem of slow congestion window (cwnd) increase, leading to underutilization of available bandwidth in environments where there is either a very large link bandwidth or frequent changes in channel characteristics. To address these issues, research on adaptive TCP congestion control using machine learning has been consistently progressing. In this paper, we propose DQN-based NewReno and DQN-based CUBIC, which enhance performance by applying a type of reinforcement learning, Deep-Q Network (DQN) to TCP congestion control algorithms. The implemented algorithms underwent performance evaluation using the Network Simulator 3 (NS3). Experimental results reveal that DQN-based CUBIC, in particular, demonstrates higher throughput compared to traditional congestion control. Additionally, fairness between different congestion control and round-trip time (RTT) fairness is also improved.

Purpose: To determine the influence of morphologic classification based on optical coherence tomography (OCT) on epiretinal membrane (ERM) surgery outcomes. Methods: We retrospectively reviewed the medical records of 77 eyes with ERM treated by vitrectomy with ERM peeling. By using OCT, the preoperative ERM was classified into four types: diffuse (DIF), cystoids macular edema (CME), pseudolamellar hole (PLH), and vitreomacular traction (VMT). The postoperative changes of central macular thickness (CMT) and best-corrected visual acuity (BCVA) were compared. Results: Approximately six months postoperatively, the DIF type had the best BCVA for both idiopathic and secondary ERM, followed by the PLH, CME, and VMT types. On the other hand, regarding the mean BCVA improvement, the VMT type was the best, followed by the DIF, PLH, and CME types. When comparing the difference in BCVA improvement by each type, idiopathic ERM showed a clearer distinction when the inner segment/outer segment (IS/OS) junction was not disrupted. Conclusions: BCVA improvement was significantly different depending on the morphologic classification of ERM by using OCT. Especially in cases of ERM with an intact IS/OS junction, the morphologic classification can help predict surgical outcomes. J Korean Ophthalmol

PLD법으로 제작한 비정질 IGZO 박막 트랜지스터의 UV광 조사 연구

서상진,조진형,김철환,장윤형 한국물리학회 2014 새물리 Vol.64 No.8

We have investigated the transport properties of amorphous InGaZnO (a-IGZO) thin film transistors (TFTs) fabricated by using the pulsed laser deposition (PLD) method. The threshold voltage (V_t) was shifted to a positive bias by both an increase in the oxygen partial pressure during the deposition and an increase in the during post heat treatment. This shift was due to decreases of the numbers of interface defects and free electron carriers caused by the reduction in the number of oxygen vacancies. In the KPFM (Kelvin probe force microscopy) measurements, the histogram data showed that the surface potential decreased with time due to a reduction in the number of oxygen vacancies because the measurements were performed in air. UV illumination resulted in a negative shift of the V_t in the absence of any bias stress. A persistent negative shift of the V_t was observed after removal of the UV illumination due to the photo-induced hole trap state in the interface, and sufficient time was needed to recover to the initial V_t. 펄스 레이저 증착 (pulsed laser deposition, PLD)법을 이용하여 비정질 InGaZnO (amorphous InGaZnO, a-IGZO) 박막트랜지스터 (thin film transistor, TFT)를 제작하고 그 전달 특성 (transfer characteristics)을 조사하였다. 증착 시 산소 분압 (50, 80 and 100 mTorr)의 증가 및 후 열처리 (300℃ , 1 hour)에 의해 문턱 전압 (threshold voltage, V_t)은 양의 방향으로 이동하였다. 이와 같은 문턱전압 이동은 산소 공공 (oxygen vacancy)의 감소에 의한 캐리어의 감소뿐 아니라 채널층과 게이트절연층 사이에 존재하는 계면결함의 감소 때문으로 보인다. KPFM (Kelvin probe force microscopy)을 이용한 a-IGZO 박막의 표면전위 측정 실험에서는 대기 노출에 의해서 표면전위분포가 시간이 지남에 따라 감소하는 것으로 나타났다. 또한 UV 광 조사에 의해 V_t는 음의 방향으로 이동하였다. UV 광 제거 후에도 a-IGZO와 SiO$_2$ 계면의 강한 홀 트랩 때문에 초기 값으로 회복 (recovery)하기 위해서는 충분한 시간이 필요한 것으로 나타났다.

그리피스 존(Griffith John)의 『상뎨진리(上帝眞理, The True Doctrine of God)』에 나타난 신론 연구

서상진 한국복음주의조직신학회 2024 조직신학연구 Vol.48 No.-

영국 런던선교회 출신 선교사로 중국 화중 선교의 아버지로 일컫는 그리피스 존이 저술한 『상뎨진리』는 언더우드에 의해 한글로 번역되어 그리스도셩서 출판사에서 1891년에 발행되었다. 그리피스 존이 『상뎨진리』 를 저술할 당시 중국의 상황은 열강들의 중국 침략으로 중국인들이 서양인들에 대한 반감이 고조에 달했을 때이다. 그리피스 존은 서양인에 대한 반감과 비호의적인 반응 속에서 중국인들이 가지고 있는 감정을 극복하고, 하나님이 어떤 분이신지를 적극적으로 변증해 나갔다. 본 논문에서 그리피스 존이 『상뎨진리』를 통해서 내세운 상제의 개념과 의미와 관련된신학적 사항을 논구해 보았다. 재중 선교사들의 한문 번역 문서에 관한 연구와 관련된 선행 연구가 미비한 상황에서 『상뎨진리』에서 말하고 있는신론을 연구하는 것은 의미가 있다. 이 연구를 통해서 그리피스 존은 당시 역사 속에서 널리 퍼져 있는 전통 종교와 문화의 자부심 속에 있는 중국인들에게 그들이 섬기고 있는 상제를 부정하고, 이 세상을 창조하신 창조주 하나님이 유일한 상제임을 변증한다. 『상뎨진리』에 나타난 신론을 논증하는 과정은 『상뎨진리』를 저술한 목적과 하나님을 상제로 사용한 역사적인 맥락과 상제에 담긴 속성과 증명을 논구했다. 또한 중국의 전통적종교인 유교와 불교의 비판을 통해 성경에서 말하는 상제의 유일성과 기독교의 핵심이라고 할 수 있는 유일하신 여호와 하나님을 믿음의 대상으로 삼아야 하는 이유를 논증했다. 그리피스 존의 『상뎨진리』는 훗날 『덕혜입문』으로 확장 재편집되어 중국과 한국에서 출간되었으며, 많은 사람을 주께로 돌아오게 하는 데, 도구로서 역할을 감당한 책자라고 할 수 있다. 『상뎨진리』의 연구를 통해 재중 선교사들에 의해 저술된 한문 소책자들에 관한 연구가 다양하게 진행되는 마중물이 되어 초기 한국교회의 신학 사상을 연구하는데 기초가 되기를 바란다. The book The True Doctrine of God, written by Griffith John, a missionary from the London Missionary Society and referred to as the father of missionary work in central China, was translated into Korean by Underwood and published by the Christology Publishing House in 1891. At the time Griffith John wrote The True Doctrine of God, the situation in China was marked by the invasion of foreign powers, leading to heightened resentment among the Chinese towards Westerners. In the face of this animosity and negative reactions, Griffith John sought to overcome the feelings held by the Chinese and actively defended the nature of God. This paper examines the theological aspects related to the concept and meaning of God as presented by Griffith John in The True Doctrine of God. Given the lack of prior research on the Chinese translations of documents by missionaries in China, studying the theology contained in The True Doctrine of God is significant. Through this research, it is demonstrated that Griffith John refuted the concept of God as understood in traditional religions and cultures prevalent among the Chinese at the time, asserting that the Creator God, who created the world, is the one true God. The process of arguing the theology presented in The True Doctrine of God discusses the purpose behind its writing, the historical context in which God is referred to as the true God, and the attributes and proofs associated with this concept. Additionally, through critiques of traditional Chinese religions such as Confucianism and Buddhism, the paper argues why the one true God, Jehovah, as described in the Bible, should be the object of faith. Griffith John’s The True Doctrine of God was later expanded and re-edited into The Gate of Virtue and Wisdom, published in China and Korea, serving as a tool to bring many people back to the Lord. Through the study of The True Doctrine of God, it is hoped that this will serve as a catalyst for diverse research on the Chinese-language booklets written by missionaries in China, laying a foundation for the study of the theological thoughts of the early Korean church.
