김준수 ( Kim Jun-soo ) 한국중국언어학회 2017 중국언어연구 Vol.0 No.71

Since the last century, many scholars' efforts have contributed to revealing that Old Chinese was a language in which relatively abundant changes in the form of words took place on the contrary to Modern Chinese. This study discussed ablaut phenomenon, which has been relatively less studied compared with the prefix or suffix. In particular, among 16 groups of cognate words that were presented in the study of Pulleyblank (1973) as words formed by ablaut, this study examined two groups of ― wei 圍(^*G^wЩl)/ wei 衛(^*G^wads) and he 合(^*guːb)/ hui 會(^*goːbs) that can be verified using Chinese paleography data. In addition, the main vowel discrepancy between yi 抑(^*?ŋЩg) and yang 仰(^*ŋaŋ?) that was left as a future task in the study of Kim, Jun-soo 金俊秀 (2016b) was also explained as an example that reflects ablaut phenomenon.

Currently, there is a drain of natural resources, environmental contamination, generation of waste, and problems of the earth's climate by CO₂ emissions according to mass production and overconsumption of mankind. It is effectuated by a linear economy that involves manufacturing products, use, and waste repeatedly; there is no guarantee in the lives of humans and the future of the globe if we do not find alternative proposals. For a sustainable developing society and to overcome the present global problems, we must successively change to a circular economy from a linear economy. The circular economy has the concept of an extended value chain in recovery, reuse, remanufacturing, and recycling, instead of discarding after the use of manufactured goods. New business models of circular economy have been realized to save the earth ecology and sustainable developing society in serious recognition of the linear economy system. New business models are established by creating a vision and developing a program, and by renovating technology, law, and financial support through a worldwide government policy.

Objectives : The purpose of this study is to compare the effects of Pharmacopuncture Treatment with Chuna Treatments for Low Back Pain caused by Traffic accidents. Methods : This study was carried out on 81 patients with low back pain caused by Traffic accidents. The patients were divided into 2 group ; The pharmacopuncture(A) group was treated by pharmacopuncture treatment. The chuna(B) group was treated by chuna treatment. We measured Oswestry Disability Index(ODI) and Visual Analog Scale(VAS) on the patients before the treatment and on the 2nd, and 4th weeks after the treatments. Results : After being treated by our methods, the ODI and VAS score's were improved after the 4th weeks treatment in both groups. There is no significant difference on ODI and VAS score after the 4th weeks treatment in both groups. In the early stages(from pre to 2 weeks worth of treatment), Group A showed a decreasing VAS score compared to Group B. In the final stages(from 2 weeks to 4 weeks worth of treatment), Group B showed a higher decreasing amount compared to Group A in VAS score. Conclusions : The results suggest that both pharmacopuncture treatment and chuna treatment is considered to be effective and useful on low back pain caused by traffic accidents. There is no significant difference between pharmacopuncture treatment and chuna treatment for low back pain caused by traffic accidents, however the early stages of treatments(from pre to 2 weeks treatement) show that pharmocopouncture treatment is more effective than chuna treatment for low back pain by traffic accidents. In the final stages(from 2 weeks to 4 weeks treatment), chuna treatment is more effective than pharmacopuncture treatment for low back pain by traffic accident.

펄스 corona 배향된 비선형광학 고분자박막의 제2 고조파발생

김준수,이종하,이황운,김상열,원영희,Kim, Jun-Soo,Lee, Jong-Ha,Lee, Hwang-Un,Kim, Sang-Youl,Won, Young-Hee 한국광학회 2002 한국광학회지 Vol.13 No.4

The molecular orientational dynamics of the nonlinear optical(NLO) side-chain polymer N-(4-nitrophenyl)-(L)-prolinol-poly (pphenylene terephthalates) have been studied using nonlinear optical responses as measured by second harmonic generation (SHG). A new pulsed corona poling is used to orient the NLO chromophores and the polymer segments into the noncentrosymmetric structure required to obtain the SHG signal. By corona poling of negative high voltage pulses with variable repetition rates (between 0.5 and 10 ㎑) at temperature between 25$^{\circ}C$ and 80$^{\circ}C$, well below and about the glass transition temperature 70$^{\circ}C$, the side-chain chromophores and the polymer chain contour rearrange themselves and create the domain structure observed by atomic force microscopy(AFM). The pulsed corona voltage enhances the orientational ordering of the NLO chromophores and also significantly influences the growth of SHG signal and the improved relaxation behavior after the poling field is removed, reducing the visible damage to the polymer film dramatically. This new pulsed corona poling experiment gave direct in situ evidence that the NLO chromophore and the polymer backbone undergo anisotropic rearrangement during the poling process. 비선형광학(NLO) 곁가지형 고분자계 N-(4-nitrophenul)-(L)-prolinol-poly (p-phenylene terephthalates)로 제작된 박막의 분자 배향거동을 제2 고조파발생(SHG)의 비선형광응답을 사용하여 연구하였다. 새로운 펄스 corona 배향 방법으로 NLO 발색단과 고분자 줄기를 비중심대칭 구조로 배향시켜 SHG 신호를 발생시켰다. 유리전이온도 70$^{\circ}C$를 중심으로 25$^{\circ}C$에서 80$^{\circ}C$까지 온도영역에서 반복율을 0.5 ㎑에서 10 ㎑까지 변화시키면서 인가한 펄스 고압으로 corona 배향한 결과로 곁가지 발색단과 고분자 주사슬이 스스로 재 정렬하여 형성한 구역구조를 원자간력 현미경(AFM)으로 관측하였다. 펄스 corona 전압 인가로 NLO 발색단 배향도가 증가되고, 동시에 고분자박막의 가시적손상을 획기적으로 줄이면서 SHG 신호가 증대되었으며 배향 후 이완거동도 개선되었다. 이 새로운 펄스 corona 배향 실험으로 NLO 발색단 및 고분자 주사슬이 배향과정에서 비등방으로 재배열하는 현상을 in situ로 입증할 수 있었다.

김준수,설영윤,이두용,박기태,김태훈,최재혁,이원주,Kim, Jun-Soo,Seul, Youngyoon,Lee, Du-Yong,Park, Kitae,Kim, Tae Hun,Choi, Jae-Hyuk,Lee, Won-Ju 해양환경안전학회 2021 해양환경안전학회지 Vol.27 No.4

본 연구에서는 상용화된 로프절단장치 타입 중 국내에 가장 많이 도입되어있는 Scissor type을 대상으로 유한요소해석을 수행하여 다양한 로프 걸림 상황에서 안정성이 확보되는 적합한 구조 형태를 평가하였으며, 수조 실험 및 실선 실험을 통해 효용성을 검증하였다. 연구 결과, 로프 걸림에 의하여 프로펠러축이 회전하지 않을 경우 엔진에서 발생하는 지속적인 토크로 인하여 로프절단장치에 비틀림이 발생하고 유한요소 해석상 자유도가 구속되어 있지 않은 하부의 블레이드에서 가장 높은 변형이 발생하는 것을 확인하였다. 블레이드의 두께가 증가할수록 최대변형량은 줄어들고 최대응력은 낮아져 안전율이 증가하는 결과가 나타났으며, 동일한 블레이드 두께에서 토크의 변화량이 최대응력과 최대변형량에 미치는 영향은 로프절단장치의 외력이 미치는 위치와 무관하며 정비례하게 감소하는 것으로 나타났다. 해석 결과를 토대로 실시한 수조실험 및 실선실험 결과, 모든 조건과 환경에서 로프 및 어망이 원활하게 제거되는 것을 확인하였다. The scissor-type rope cutter is the most widely used amongst all kinds of commercially available rope cutters in Korea. In this study, we performed finite element analysis on the scissor-type rope cutter. We determined the structure of the cutter that would ensure its stable operation in various situations involving rope entanglement, and verified its effectiveness by testing it in the lab and in an actual ship. These investigations revealed that when the propeller shaft was not rotated by rope entanglement, the constant torque generated by the engine resulted in the torsion of the rope cutter and maximum deformation in the lower blade, which was not restricted by finite element analysis. With increasing blade thickness, the maximum values of deformation and equivalent stress decreased, resulting in a rise in the safety factor. At the constant blade thickness, the effect of the torque variations on the maximum equivalent stress and the maximum deformation is independent of the position of the external force of the rope cutter and decreases in direct proportion. The results of this study confirmed that the rope-cutter structure determined by analysis could lead to a hassle-free removal of ropes and fishing nets under all conditions and environments.

김준수,조준희,김학윤,조현제,Kim, Jun-Soo,Cho, Joon-Hee,Kim, Hak-Yun,Cho, Hyun-Je 한국산림과학회 2019 한국산림과학회지 Vol.108 No.2

대구광역시에 자생하고 있는 모감주나무군락의 종조성과 구조 그리고 개체군 동태를 파악하기 위하여 2018년 7월에 자생 임분 3곳을 선정하여 식물사회학적 식생조사와 매목조사를 실시하였다. 야외에서 수집된 식생 및 매목조사 정보를 바탕으로 종조성에 의한 군락 유형을 구분하고 그 유형별 계층구조, 구성 종의 상대 중요치, 생활형 조성, 종다양성, 그리고 개체군 구조 등을 분석, 비교하였다. 군락 유형은 참느릅나무-좀목형아군락, 광대싸리아군락, 그리고 사위질빵군락 등 3개 유형이 구분되고 그 식생단위체계는 1개 군락군, 2개 군락, 그리고 2개 아군락으로 정리되었다. 계층구조는 교목층의 높은 식피율(85% 이상)에 비하여 초본층은 10%이하로 매우 낮은 경향이었다. 구성종의 상대중요치(MIV)는 교목층 94.3, 아교목층 81.6, 관목층 75.5, 그리고 초본층 60.0으로 모든 식생 층위에서 모감주나무가 절대적으로 높게 나타났다. 종다양도(H')는 군락 유형 간 큰 차이가 있었는데 사위질빵군락(2.062)이 광대싸리아군락(0.547)에 비해 약 4배정도 높게 나타났다. 생활형 조성의 중심체계(휴면형-지하기관형-산포기관형-생육형)는 전체적으로 '$MM-R_5-D_4{\cdot}D_2-e$'로 나타났으나 군락 유형 간에는 산포기관형에 있어서 다소 차이를 보였다. 모감주나무군락의 개체군 구조는 3개 군락 유형에서 모두 어린 개체의 밀도가 높고 크기가 큰 개체의 밀도가 낮은 역J자형의 모양을 나타내고 현재의 하층식생을 구성하고 있는 식물 중 모감주나무 개체군을 대체할 만한 식물종이 없으므로 지속적 유지가 가능한 개체군으로 판단되었다. To understand the floristic composition, vegetation structure, and population dynamics of Koelreuteria paniculata communities, which are native to Daegu, South Korea, a field survey was conducted in July 2018 using phytosociological and complete enumeration methods. Based on information on vegetation and trees of >5 cm diameter at breast height collected during the field survey, we classified the community types by species composition and analyzed their vegetation strata, relative importance value (MIV), life forms, species diversity, and population structure. The community was divided into the following three types: Ulmus parvifolia-Vitex negundo var. incisa subcommunity, Securinega suffruticosa subcommunity, and Clematis apiifolia community. The vegetation unit system was organized into one community group, two communities, and two subcommunities. Vegetation coverage of the tree layer was >85%, while the herbaceous layer was <10%. MIV of K. paniculata appeared to be extremely high within all vegetation strata, with 94.3 of the tree layer, 81.6 of the subtree layer, 75.5 of the shrub layer, and 60.0 of the herbaceous layer. The species diversity (H') was significantly different among the community types, and the C. apiifolia community (2.062) was approximately four times higher than the S. suffruticosa subcommunity (0.547). The overall representative life form types were "$MM-R_5-D_4{\cdot}D_2-e$,", but there were some differences in the disseminule form among the community types. The population structure of K. paniculata showed the reverse J-shaped distribution with a high density of young individuals and low density of larger individuals among all three community types, and because no plant species within the lower vegetation could replace K. paniculata, it was considered to be a sustainable population.

It is important to predict and measure the combat effectiveness (CE) of weapons system in battlefield for acquiring efficient weapon system. Moreover, quantitative calculation of weapon effectiveness under complicated and uncertain battlefield environment is also difficult based on the future network centric warfare. Many papers used the term of combat effectiveness and tried to study a lot of related issues about it. However, there is no paper dealing with the classification of study issue about CE and what will happen in this study field. In this paper, we proposed how to classify the study issue about CE and forecast future direction of this study field. Conceptually, CE is nothing but the assessment results to measure the ability of a military weapon system to accomplish its objective. We believe that it is an appropriate time to review the literature extensively on CE analysis because the research interests and the papers of CE are rapidly growing in these days. This paper reviewed many CE analysis papers, classified them according to their research content and the research methodology applied. Additionally, a comprehensive list of future research areas is also given.
