폭발합성법에 의한 Ti5Si3 계 금속간화합물의 합성

강봉용,황선근,류회수,김상우 대한금속재료학회(대한금속학회) 1998 대한금속·재료학회지 Vol.36 No.10

Synthesis of an intermetallic compound based on Ti_5Si₃ by an explosive compaction of elemental powders was studied. The main experimental variable was the detonation velocity, and it was found that the relative density of the compacted compound increased with the detonation velocity. To enhance the density of the compound further, however, it was deemed necessary to consider variables such as the can, powder and the backup tube. From an X-ray diffraction analysis of the explosion-compacted compound it was confirmed that formation of the Ti_5Si₃ phase was complete. Apart from the needs to further improve the density and crack resistance of the compacted alloy, the present work indicates that the explosion synthesis has a potential to be developed as a consolidation method for Ti_5Si₃ intermetallic compounds.

한국교회의 설교비평

Ryoo,Eung-Yul 개혁신학회 2008 개혁논총 Vol.9 No.-

This writer tries to examine the current situation regarding the sermon criticism of Korean churches and propose a few things to establish the foundation of biblical preaching in Korean churches through this paper. In fact, the word, sermon criticism is being used very rarely not only in the Korean churches but also in the Western churches. And it can not be easily found in the western homiletic world as far as books or papers regarding the sermon criticism are concerned. In the midst of this current situation, Korean churches begin to have a great interest in a sermon criticism.But the sermon criticism based on the wrong theology might be cause for wrong preaching and a great danger to impede wholesome words. On the other hand, the interest regarding the right sermon criticism based on biblical theology will play a far bigger part in making the pulpit as the word of truth. For this purpose, I will take a look at the history of sermon criticism in Korean churches. Then secondly, I would like to analyze the contents of the sermon criticism and evaluate its validity. Finally, I try to make five suggestions in order to make right sermon criticism settled in Korean churches. First, the biblical homiletic theology should be in a triangular position for the right sermon criticism of the pulpit of Korean churches. Second, for the balanced criticism, preachers and their sermon must be studied simultaneously. Third, sublation of criticism with a critic's viewpoint to his heart's content and a hermeneutical critique attitude toward analyzing the sermon with respect of preachers’intention must be provided. Fourth, the same interest not only in the preachers’body of sermon but also in the delivery of sermon must be needed as well. Fifth, a sermon must be comprehended under the live worship circumstance on account of a sermon being dynamic in the background of every service. The word of God through preaching is not an object of a critique but the object of obedience. But preaching can be developed by the creative criticism. I hope that the pulpit experiences the holy change in every sermon in accordance with sermon criticism positioning as a constructive academic field, and with the sermon of Korean churches putting down new roots in the Bible drastically, and permeating into auditors’lives accurately.

Using the Korean Translation of Disney’s Mulan to Learn About Cross-Cultural Awareness

Ryoo,Hyunjin,Cho,Sung-Eun 영상영어교육학회 2017 영상영어교육 (STEM journal) Vol.18 No.3

This paper is an attempt to learn about cross-cultural issues using the Korean dubbed and subtitled translation of Disney’s Mulan. The concept of ‘Cultural Re-saturation’ is introduced as a form of domestication chosen as a translational solution when the target culture (TC) audience knows more about the source text (ST) context than the source culture (SC) audience. Mulan is created under distinct circumstances: although based on the Ballad of Mulan, a Chinese cultural legacy, it was scripted and made by the American animation studio, Walt Disney Pictures. The original English dialogue of the film, the dubbed version and the subtitles of the official Korean DVD of Mulan were analyzed to present a model for the study of cross-cultural awareness through translation. The resulting Korean target text (TT) tends to carry a lot more cultural nuances than the original American source text, as the text is adapted to suit an audience more informed of the cultural context. Defining this phenomenon as Cultural Re-saturation, this paper attempts to portray the prevalence of this tactic within the official translations of Mulan and aims to provide a means for gaining an enhanced cross-cultural understanding of the complexity and subtlety of culture and language.

일반화된 신호 압신법에 기반한 향상된 차분전력분석 방법

최지선,류정춘,한동국,박태훈,Choi, Ji-Sun,Ryoo, Jeong-Choon,Han, Dong-Guk,Park, Tae-Hoon 한국정보처리학회 2011 정보처리학회논문지 C : 정보통신,정보보안 Vol.18 No.4

차분전력공격(Differential Power Analysis, DPA)의 효율성은 수집신호 정렬도를 비롯한 다양한 잡음에 많은 영향을 받는다. 최근에 Ryoo등은 잡음 신호를 극복하여 DPA의 분석성능 향상을 가져오는 효과적인 신호처리기법을 소개했다. 본 논문에서는 기존에 제안된 신호처리기법이 적용되지 않은 경우를 보이고, 이에 대한 해결방안으로 차분파형모델(Differential Trace Model, DTM)을 제안한다. 또한 제안된 DTM이 DPA 분석에 적합한가에 대해 이론적으로 증명하고 실험을 통해 검증한다. Differential Power Analysis is fully affected by various noises including temporal misalignment. Recently, Ryoo et al have introduced an efficient preprocessor method leading to improvements in DPA by removing the noise signals. This paper experimentally proves that the existing preprocessor method is not applied to all processor. To overcome this defect, we propose a Differential Trace Model(DTM). Also, we theoretically prove and experimentally confirm that the proposed DTM suites DPA.

Life history and intrinsic rate of natural increase of the rice weevil, Sitophilus oryzae (L.) (Coleoptera: Curculionidae) in rice

백미에서 쌀바구미의 내적자연증가율은 2$0^{\circ}C$, $25^{\circ}C$, 3$0^{\circ}C$에서 각각 0.1759, 0.3242, 0.4798로 산출되었으며 실험온도역에서 일차 직선적 관계를 보였다. 평균세대기간은 해당온도에서 각각 18. 8, 10.5, 7. 1주로 추정되었다. 밀에서 보고된 쌀바구미의 생활사와 비교 했을때 백미에서의 동곤충의 증가율은 낮은 것이었으며 또한 세대기간에 미치는 온도효과는 더 현저한 것으로 나타났다. 이러한 현상은 밀에서의 그것에 비해 백미에서 쌀바구미의 총산란수가 적고, 동시에 연령에 따른 산란분포가 상이한 것에서 기인되는 것으로 사료된다. The intrinsic rate of natural increase of the rice weevil in polished rice was estimated to be 0. 1755, 0.3242 and 0.4789 per head per week at 20$^{\circ}C$, 25$^{\circ}C$ and 30$^{\circ}C$, respectively. The mean generation time was 18.8, 10.9 and 7. 1 weeks at the temperatures, respective. In comparison with the reports published in wheat, the life history phenomena were somewhat different: the rate was lower and the generation time was more sensitive to the temperature in polished rice than in wheat. Since other characteristics affecting the rate (development time, mortality during development and longevity of adults) were similar in both medium, differences in the life history phenomena could be due to the lower fecundity and its distribution pattern in relation to female age.

Acupuncture effect on Chemotherapy-induced Vomiting and Nausea: A case series

Ryoo, Hun Mo,Kim, Dae-Jun The Society of Korean Medicine 2015 대한한의학회지 Vol.36 No.4

Objectives: We carried out an observational study of the effects of Nei Guan (P6) and Gong Sun (SP4) acupuncture for the treatment of CINV, preparing for further randomized controlled trial study. This is a case series to explore the changes in the incidence of CINV by acupuncture. Methods: Patients reported a Rhodex index indicating the severity of nausea and vomiting and loss of appetite, before acupuncture, after acupuncture and 1-week follow-up examination. Twelve patients with CINV participated in this study. We included patients receiving chemotherapeutic agents that might induce moderate or severe nausea and vomiting. We conducted 5 treatment sessions with P6 and SP4 acupuncture over the course of 5 days. Results: The median Rhodex score were decreased in 5 patients over time, while we observed loss of appetite of 6 patients were improved over time. During the study, the mean of Rhodex of total patients revealed a decrease of Day 1, Day 7, Day 14; 0.74, 0.68, 0.38, respectively, while the mean of loss of appetite showed a decrease of Day 1, Day 7, Day 14; 5.25, 4.08, 4.00, respectively. Conclusions: The study gives a preliminary data that manual acupuncture of P6 and SP4 may reduce the severity of CINV and loss of appetite, and justifies further study.
