김형순,김완영,김영자 ( Hyung Soon Kim,Wan Young Kim,Young Ja Kim ) 한국공업화학회 1996 공업화학 Vol.7 No.5

에폭시 수지를 접착제의 base resin으로 이용하기 위해 DGEBA/dicy계의 경화특성을 조사하였다. dicy는 상온에서 저장안정성이 우수하여 일액형 접착제의 경화제로서 유용하다. 그러나 고온에서 경화시 열분해될 우려가 있으므로 경화온도를 낮추기 위해 diuron을 경화촉진제로 사용하였다. Epoxy/dicy계에서 dicy의 사용량이 증가함에 따라 경화반응열이 증가하였으며, 경화 후 수지의 유리전이온도(T_g)도 증가하는 것으로 관찰되었다. Diuron을 경화촉진제로 사용함으로써 약 40℃정도 낮은 온도에서 경화반응이 진행되었으며, 수지의 유리전이온도는 감소되었다. 경화반응의 속도론적 고찰은 Kamal이 제안한 자촉매반응의 모델식으로 해석하였으며, diuron의 경화촉진 효과를 확인할 수 있었다. Cure characteristics of DGEBA(diglycidyl ether of bisphenol A)/ dicy(dicyandiamide) system containing diuron(3-(3,4-dichloro phenyl) -1,1-dimethylurea) as an accelerator was investigated. The system has shelf life of six months because dicy is insoluble in liquid/solid resins at room temperature. It is generally known that dicy is an adequate curing agent for one component adhesive due to its highly latent property. With increasing the amount of added dicy, reaction heat of DGEBA/dicy system increased and degree of conversion was not varied. For DGEBA/dicy /diuron system, cure temperature decreased about 40℃ and cure reaction became fast by the addition of diuron which activates dicy. T_g of the mixed resin decreased with the amount of accelerator, which was interpreated with molecular structure forming loose chain. Cure kinetics of DGEBA/dicy and DGEBA/dicy/diuron system were explained using Kamal`s autocatalytic reaction model. The effect of acceleration was confirmed with that reaction model.

Speaker change detection is to detect automatically a point of time at which speaker was replaced. Since feature parameters used for speaker change detection depend not only on speaker characteristics but also on phonetic characteristics, spoken contents included in the feature parameters inevitably causes performance degradation of speaker change detection. In this paper, to alleviate this problem, a method to normalize phonetic variations in speech feature parameters is proposed for emphasizing changes due to speaker characteristics. Experimental results show that the proposed method improves the performance of speaker change detection.

이제마(李濟馬)의 형상관(形象觀)이해와 안면부(顔面部) 형태의 해석

김형순,최광진,Kim, Hyung-soon,Choi, Kwang-jin 사상체질의학회 1999 사상체질의학회지 Vol.11 No.1

이제마(李濟馬)는 각 체질의 판단을 위해 체형기상(體形氣像)등의 방법을 제시하였으며, 이를 바탕으로 우리는 여러 가지 다양한 방법의 체질판단을 시도할 수 있다. 그러한 이론의 바탕에는 이제마(李濟馬)의 행위결정론적 사고방식이 강하게 뿌리박고 있다. 이는 "성명론(性命論)"의 '두견요둔(頭肩腰臀)', '이목비구(耳目鼻口)', '함억제복'등의 단어들을 볼 때, 기존처럼 형(形)을 상(象)을 반영하는 객체로 인식하는 것이 아니라, 하나의 부분 주체적 개념으로 인식하고 있는 것을 보면 알 수 있다. 이로 보아 이제마(李濟馬)는 인체의 각 부위에 대하여 기존에 가지고 있던 육체적 기능뿐만 아니라 복잡한 성정적(性情的) 기능도 가지고 있다고 본 것이다. 이러한 고찰과 인체의 외형에 대한 직접적 서술이 있는 "장부론(臟腑論)" 등을 종합해 보면 현재 이용하고 있는 체질판단의 체형기상(體形氣像) 부분에 대하여 일정한 이론을 가지고 설명할 수 있다고 생각하여 다음과 같은 가설을 제시하여 보았다. "사단론(四端論"과 "확충론(據充論)"을 볼 때, 사상인(思象人)의 직부대소(職腑大小)는 태음인(太陽人)의 경우 폐(肺) > 비(脾) > 신(腎) > 간(肝)의 순으로, 소양인(少陽人)은 비(脾) > 폐(肺) > 간(肝) > 신(腎)의 순으로, 태음인(太陰人)의 경우 간(肝) > 신(腎) > 비(脾) > 폐(肺), 소음인(少陰人)은 신(腎) > 간(肝) > 폐(肺) > 비(脾)의 순으로 생각할 수 있으며, "직부론(職腑論)"에서 사람의 형(形)이 형성되는 과정 중에 보이는 '신기혈정(神氣血精)'이라는 개념은 형(形)의 생성과 관련이 있음과 아울러 각 직국(職局) 및 애노희락(哀怒喜樂)의 기운과 통한다라고 할 수 있다. 이러한 관점에서 사상인(四象人)을 분류해 보면, 태음인(太陽人)을 신기정혈형(神氣精血型), 소양인(少陽人)을 기신혈정형(氣神血精型), 태음인(太陰人)을 혈정기신형(血精氣神型), 소음인(少陰人)을 정혈신기형(精血神氣型)으로 분류할 수 있을 것이다. 이러한 역량관계에 따라 각 체질의 외형에 대하여 일정한 설명방법을 도입해 보았으며, 이러한 시도를 바탕으로 사상의학의 형상에 대한 논의가 활발해졌으면 하는 바램이다. Lee, Je-ma proposed ways like Chehyungkisang to judge each constitution, so, on the basis of this, we can judge constitution in various ways. Such a theory is based on behavior determinism's way of thinking of Lee, Je-ma. We can know this that form is not recognized as an object reflecting image, but a subjective concept from Tukyonyodun, Yimokbiku(ears, eyes, nose and mouth), Hameokjebok of Sungmyong Theory. Lee, Je-ma thought each part of human body has not only physical function but also complex temperative function. Putting this consideration and Jangbu Theory describing human body directly, together, it can be said that these all have an established theory on Chehyungkisang of constitution judgement. Thus, the following hypotheses are given. From Sadan Theory and Hwakchung Theory, strength of Jangbu of Sasangin is Pe>Bi>Shin>Kan in Taeyangin and Bi>Pe>Kan>Shin in Soyangin and Kan>Shin>Bi>Pe> in Taeumin and Shin>Kan>Pe>Bi in Soumin. The concept of Shinkihyuljung is related with creation of form and spirit of each Jangkuk and Aenoheerak(sorrow, anger, joy, pleasure). From this viewpoint, Sasangin can be classified into; Taeyangin into Shinkijunghyul type, Taeumin into Hyuljungkishin type, Soumin into Junghyuishinki type. Introduced a fixed way to explain of each constitution according to this strength relationship. I hope more lively discussions on Constitutional Medicine will be continued based on this attempt.

음성/음악 판별을 위한 특징 파라미터와 분류기의 성능비교

In this paper, we evaluate and compare the performance of speech/music discrimination based on various feature parameters and classifiers. As for feature parameters, we consider High Zero Crossing Rate Ratio (HZCRR), Low Short Time Energy Ratio (LSTER), Spectral Flux (SF), Line Spectral Pair (LSP) distance, entropy and dynamism. We also examine three classifiers: k Nearest Neighbor (k-NN), Gaussian Mixure Model (GMM), and Hidden Markov Model (HMM). According to our experiments, LSP distance and phoneme-recognizer-based feature set (entropy and dunamism) show good performance, while performance differences due to different classifiers are not significant. When all the six feature parameters are employed, average speech/music discrimination accuracy up to 96.6% is achieved.

Korea real estate appraisal business tends to sit on the national protection frame in the meantime, such as living peacefully oneself, and giving up the change of their business concepts matching to the newly changed companies in recent years. As a result, internal competition became excessive and reliance of the business has fallen. In order to correspond to the environment change, appraisal business have to develop the new field. According to the BCG(Boston Consulting Group) model, P area which is higher growth and lower market portion is most appropriate for the new filed. Specially appraisal for the real estate indirect investment, real estate consulting service, and overseas appraisal fields are a new opportunity for the appraiser, that is P area in the BCG model. But the appraiser which is going to search the new field must plan a detailed strategy in consideration of its ability and environment. The prospects of the appraisal field are dependent upon the appraiser itself. Therefore the appraiser must expend the new field rather than seeking a place for peaceful living. It is time that we conceived of Blue Ocean strategy.

The effects of various operating parameters(agitation speed, impeller type, antiform agents, impeller spacing etc.) on air-liquid mass transfer was characterized by volumetric mass transfer coefficient(k??a). Also, the dual-impeller agitated systems are compared with single-impeller agitated systems with a special focus on its applications for bioreactors, k??a was take over a range of 200~450 rpm of agitation speed, and 0.5~2.5 vvm of air flow rates, for four single impeller and impeller combinations consisting of four impeller types, namely rushton, pitched blade, scaba, intermig were tested. The rush ton impeller showed the best k??a as compared with other single impellers. The dual impeller system are found to be superior as compared to single impeller in all aspects, The best combination of the dual impeller was a intermig of axial flow type as an upper impeller and a rush ton of radial flow type as a lower part. Also, the control of the DO level with the variation of agitation speed was more efficient than that with an increase in air flow rate. The addition of antiform dropped the k??a very large up to 19/L regardless the type. PPG was less effect on k??a than other antiforms. The impeller spacing and presence of solute are found very effective on k??a. When the NaNO₃is presented as solute, the k??a increased approximately 50% then control.<br/> <br/> <br/>
