Kim(2002)은 축점의 위치가 두 개의 수에 의하여 정해지는 제2종의 중심합성계획을 제시하고 이를 CCD2라 불렀다. 본 논문에서는 CCD2를 더욱 연구하여 몇 가지의 새로운 사실을 밝혔다. 직교성과 회전성, 직교성과 기울기회전성, 회전성과 균등정밀성을 동시에 갖는 CCD2들을 구하였으며, Park과 Kim(1992)이 제시한 기울기회전성의 측도를 이러한 CCD2들에 적용하여 그 결과를 관찰하였다. Kim(2002) proposed a second type of central composite design in which the positionsof the axial points are indicated by two numbers, and called it CCD2. In the present paper, we have studied CCD2 further and obtained several new facts. We have obtained CCD2's that have both orthogonality and rotatability, both orthogonality and slope rotatability, and both rotatability and uniform precision. We also have applied Park and Kim's (1992) measure of slope rotatability to such CCD2's and observed some useful results.

한국 프로야구에서 수정된 WHIP와 피홈런 수를 결합한 실점 설명 수비지표들

김혁주,Kim, Hyuk Joo 한국통계학회 2016 응용통계연구 Vol.29 No.7

한국 프로야구팀들의 실점을 설명하기 위한 수비지표를 연구하였다. 출루율과 장타율을 결합한 OPS가 팀들의 득점력을 매우 잘 설명한다는 사실을 동기로 하여 본 논문에서는 팀들의 실점을 설명하기 위한 수비지표를 연구하였다. 여러 가지의 수비지표 중 팀의 실점과 상관관계가 높은 것들을 결합하여 만든 몇 가지의 결합 지표들을 고려하였다. 프로야구 원년인 1982년부터 2015년까지의 정규리그 전 경기 자료를 분석한 결과 수정WHIP와 이닝당피홈런의 가중평균으로 정의되는 가중수정WPH2가 실점을 가장 잘 설명해줬다. 구체적으로 수정WHIP에 34%, 이닝당피홈런에 66%의 가중값을 두는 가중수정WPH2가 팀의 경기당 평균실점과 0.95362의 상관계수를 갖는 최적의 지표인 것으로 나타났다. 이 결과는 Kim과 Kim (2015a)에서 얻어진 지표에 의한 결과보다 좀 더 향상된 결과이다. 시대별 분석에서도 크게 다르지 않은 결과를 얻었다. 또한 얻어진 지표의 값이 좋은 투수 10명씩의 명단을 최근 3년간에 대해 연도별로 작성해보았다. We studied fielding indices to explain runs lost for Korean professional baseball teams, successively motivated by OPS and weighted OPS obtained by combining on-base percentage and slugging average that can adequately explain the run productivity of teams. We considered several combined indices made by combining fielding indices highly correlated with the runs lost of teams. Data analysis from all games in the regular seasons of 1982-2015 shows that weighted adjusted WPH 2 (defined as weighted average of adjusted WHIP and number of home runs allowed per inning) best explains runs lost. Weighted adjusted WPH 2 consisting of adjusted WHIP (with weight 34%) and number of home runs allowed per inning (with weight 66%) was found to be optimal weighted adjusted WPH 2 having correlation coefficient 0.95362 with average runs lost per game. This result is an improvement of the result of the index obtained in Kim and Kim (2015a). Analysis by chronological periods provides results that are not much different. Also we made a list of top 10 pitchers for each of the recent three years, based on the obtained index.

김혁주,김예형,Kim, Hyuk Joo,Kim, Yea Hyoung 한국통계학회 2015 응용통계연구 Vol.28 No.5

한국 프로야구에서 팀들의 실점을 설명하기 위한 지표를 연구하였다. Kim과 Kim (2014)이 팀들의 득점력을 설명하기 위한 공격지표를 연구한 것과 유사하게 본 논문에서는 팀들의 실점을 설명하기 위한 수비지표를 연구하였다. 여러 가지의 수비지표 중 팀의 실점과 관련이 큰 것들을 결합하여 만든 몇 가지의 결합지표들을 고려하였다. 프로야구 원년인 1982년부터 2014년까지의 정규리그 전 경기 자료를 분석한 결과 WHIP와 경기당피홈런의 가중평균으로 정의되는 가중WPH가 실점을 가장 잘 설명해줬다. 구체적으로 WHIP에 81%, 경기당피홈런에 19%의 가중값을 주는 가중WPH가 팀의 평균실점과 0.95033의 상관계수를 갖는 최적의 가중WPH인 것으로 나타났다. 시대별 분석에서도 크게 다르지 않은 결과를 얻었다. We studied indices to explain runs lost for Korean professional baseball teams. Kim and Kim (2014) studied batting indices to explain run productivity of teams; subsequently, we studied fielding indices to explain runs lost. We considered several combined indices made by combining fielding indices closely connected with the runs lost of teams. Data analysis from all games in the regular seasons of 1982~2014 show that weighted WPH (defined as weighted average of WHIP and number of home runs allowed per game) best explain runs lost. Weighted WPH consisting of WHIP (with weight 81%) and number of home runs allowed per game (with weight 19%) was found optimal weighted WPH having correlation coefficient 0.95033 with average runs lost per game. Analysis by chronological periods gave results not much different.

음성인식을 위한 변환 공간 모델에 근거한 순차 적응기법

김동국,장준혁,김남수 한국음성과학회 2004 음성과학 Vol.11 No.4

In this paper, we propose a new approach to sequential linear regression adaptation of continuous density hidden Markov models (CDHMMs) based on transformation space model (TSM). The proposed TSM which characterizes the a priori knowledge of the training speakers associated with maximum likelihood linear regression (MLLR) matrix parameters is effectively described in terms of the latent variable models. The TSM provides various sources of information such as the correlation information, the prior distribution, and the prior knowledge of the regression parameters that are very useful for rapid adaptation. The quasi-Bayes (QB) estimation algorithm is formulated to incrementally update the hyperparameters of the TSM and regression matrices simultaneously. Experimental results showed that the proposed TSM approach is better than that of the conventional quasi-Bayes linear regression (QBLR) algorithm for a small amount of adaptation data.

The influence of single and repeated oral pretreatment of CHUNG-HYUL-DAN(CHD). a widely used Korean traditional herbal medicines prescribed for hypertension and hyperlipidemia, on the pharmacokinetics and pharmacodynamics of a calcium channel blocker, nicardipine after oral administration of nicardipine was investigated in rats. The single pretreatment of CHD significantly increased area under the plasma concentration-time curve(AUC_(0-8h), but did not influence the time to reach the maximum peak plasma concentration(T_(max)), the maximum peak plasma concentration(C_(max)), terminal elimination half-life(t_(1/2) or the elimination rate constant(λ) for nicardipine. And, C_(max) and AUC_(0-8h) for nicardipine were significantly increased by with 1-week repeated pretreatment with CHD, but the other parameters were not significantly different from those of control. Also, the extent of the lowering effect of nicardipine on blood pressure in rats was significantly increased after oral administration of nicardipine with single and repeated oral pretreatment with CHD. These results indicated that single and 1-week repeated oral pretreatment with CHD should inhibit the metabolism of nicardipine in rats.

The autotransplantation procedure were performed for the cases with impacted maxillary anterior teeth, which were thought unrealistic by the treatment with surgical exposure and orthodontic traction into the arches. The results were as follow : 1. As the treatment with autotransplantation is the last resort, the case indicated should be selected cautiously by adequate case analysis. 2. In order to reduce postoperative complication, damages to periodontal ligaments and adjacent bony structures should be minimized by conservative surgical procedures. 3. After autotransplantation procedures, postoperative endodonic treatment and continuous follow-up check with clinical and radiographic examination should be followed. Although the autotransplantation procedure is not the treatment of choice in most cases, it was thought to be a good alternative in certain cases when orthodontic treatment is unrealistic with continuous study to overcome the handicaps.

This study aims to investigate what influence an aerobic exercise on the physical fitness and the vital capacity of the mentally retarded adults. In order to do this successfully, an aerobic exercise is conducted on the mentally retarded adults, as the object of study, affiliated with Pusan Therapeutic Recreation Association for twelve weeks, 50 minutes everytime, once a week. As a result of this study, the conclusions are obtained as follows: First, it is represented that there is a significant difference among them in their back strength, grip strength, trunk flexion forward, side-step, sit-ups, sargent jump and stork stand. However, there is no significant difference among them in their push-ups and whole body reaction time after their 12 weeks' aerobic exercise. Second, judging from their vital capacity, it is shown that there is a significant difference (p<.01) among them in their forced vital capacity (FVC) and forced expiratory volume for 0.5 second (FEV.5), while there is no significant difference among them in the percentage of their forced expiratory volume for 0.5 second for FVC (FVC.5/FVC(%)) and peak expiratory flow (PEF). However, it is proved that in their maxical voluntary ventilation (MVV), there is a significant difference among them after 12 weeks' aerobic exercise (p<.05). Therefore, it can be seen that 12 weeks' aerobic exercise results in making much progress in the development of their physical fitness and vital capacity. In this respect, it is expected that much more various and advanced research of rehabilitation and exercise programs for the handicapped would be needed .

比較憲法에 관한 硏究 : 民主主義國家의 憲法과 共産主義國家의 憲法을 中心으로

This paper aims to make clear the fundamental differences between the constitutions of two political systems, constitutional democracy and communism. (1) Fundamental Human Rights The recognition and the protection of fundamental liberties are the essences of the political system of constitutional democacy. The reality of individual liberties is the only reliable criterion that differentiates the two political systems, since the institutional apparatus of both government, assemblies, elections, parties, bureaucracies have become stereotyped to the point of identity. Recognition or nonrecognition of fundemental guaranties are closely related to the ideological telos of either system. In the constitutional democracy they crystallize the supreme values of human self-realization and dignity. In the communist states they are denied legitimacy not only because they may function as foci of opposition against monolithic power but also because they could obstruct the ideology of economic planning under collectivism. The idelolgical foundation and functional purpose of classical fundamentalism underwent a fa -reaching transformation in the Marxian society. The Russian Revolution preaches and practices the primacy of the collectivity over the individual. Instesd of being "inalienable" interpreted as obligations of the state toward the laboring masses. The attitude of Marxism in the U.S.S.R. and the so-called "People's Democracies" toward fundamental liberties is altogether different. All constitutions in the Soviet orbit contain elaborate statements on fundamental rights of the citizens, characteristically coupled with provisions concerning their duties toword the state and the community. Civil liberties in the classical sense, which the constitution of communist states merely summarizes, are overshadowed by the new social and economic rights. The guaranty of the civil rights proper is hedged in by the rubber clause that they are guaranteed " in conformity with the interests of the working class" and "in order to strenghthen the socialist system". Especially political rights of the suffrage are converted into compulsory mass participation in the political process directed by the party hierarchy. And its single party (communist party)was the straight negation of all political liberty. (2) Patterns of Governament In the modern democratic-constitutional state the essence of the power process consists in the attempt to establish an equilibrium between the various competitive plural forces within in state society, with due regard to the free unfolding of the human personality. In communist state, social control and political power are monopolized by a single power holder, subordinating the individual to the ideological requirements of the group domination the state. The basic difference between the two political systema conists in whether, in the various stages of the governmental process, political power, is distributed among and shared by several independent power holders or whether political power is concentrated in and monoploized by a single power holder, be it an individual person, and assembly, or a party. Assembly government system revived in the Stalin constitution of 1936 in the U.S.S.R. from where it spread, after the Second World War, to all satellite states, as well as East Germany, Red China, North Korea. No communist state fails to conform to this standard pattern. Assembly government, by its own biological laws. easily transforms itself into a regime in which a single power holder exercises the monopoly of political power. This may well be the intrinsic reason for the communist preference. By necessity the communist state is a plice state. Another indispensable instrument of social control is the single party. The governmental techniques of a communist regime are necessarily authoritarian. But the regime does much more than exclude the power addressees from their legitimate share in the formation of the will of the state. It attempts to mold the private life, the soul, the spirit and the mores of the citizens to a dominant ideology that the various instrumentalities of the power process force on the non-conformists.

외상성 흉·요추접합부 파열골절의 Kaneda 기구를 이용한 내고정술에 대한 임상적 검토 : Results of Anterior Decompression and Stabilization with Kaneda Device

장주호,김수한,정신,김재휴,강삼석,이제혁 대한신경외과학회 1993 Journal of Korean neurosurgical society Vol.22 No.4

The authors report clinical results of twenty-three traumatic thoracolumbar burst fractures treated by internal fixation with Kaneda device after anterior decompression during recent three years. Thoracolumbar injuries made up 28.9% of total spinal injuries and the burst fractures treated by anterior decompression and stabilization with Kaneda device constituted 19.0% of all spinal injuries. The burst fractures occurred most frequently at the age of twenties and thirties. The main causes of injury were fall and vehicle accident. Superior end-plate fracture type was most common according to the types of burst fracture. The first and the second lumbar vertebrae were frequently involved. No patient showed neurological deterioration after surgery. Conus medullaris lesions in burst fractures of the thoracolumbar junction have a high potentiality for functional recovery because the lesions are not due to discontinuity or severe crush injury but due to simple compression by bony fragments. The Kaneda device offered enough stability to enable early ambulation with good alignment and solid fusion.
