정신분열증 환자의 지각결핍을 타 질환군과 비교해 보기 위하여 1983.6.1부터 동년 8월 31일 까지 전남의 대병원 정신과 외래에 다니는 우울증 환자 20명 국립나주정신병원에 입원한 정신분열증 환자 20명을 임의 선택하여 Garner의 모형을 이용 카드 분류를 시행하고 그 자료를 토대로 수정분류시간, 공제지수, 비율지수 등을 산출하여 변량분석한 결과 다음과 같은 결론을 얻었다. 1. 양 군의 수정시간을 변량 분석한 결과 유의한 차이를 발견할 수 없었다. 2. 공제지수와 비율지수를 변량분석한 결과 과다성 분류와 여과분류에서는 공제지수와 비율지수에서 아무런 유의차가 없었다. 3. 주사분류에서는 공제지수 비교에서 1% 수준에서 비율지수 비교에서 5% 수준으로 우울증의 분류시간이 긴 것으로 나타났다. 이상의 결과를 살펴볼 때 여과기능의 결함이라는 지각결핍은 정신분열증의 고유한 장애가 아닐 수도 있겠다. The perception of stimuli with two dimensions (size and figure) was investigated using Garners card sorting method into schizophrenic and depressive patients. The comparison of three performance indices (redundancy, filltering, scanning) between two study groups revealed that 1) the analysis of variance of the corrected time shows no significant difference between two groups, 2) in redundancy and filtering sorting the subtractive and ratio indices show no significant difference between two groups, 3) in scanning sorting the depressive group shows significantly longer sorting time than schizophrenic group(p<0.01 in subtractive index, p>0.05 in ratio index). The above findings suggest that the previously known perceptual deficit(mainly filtering deficit) may not be specific only to schizophrenia.

[연구목적] 중소기업의 생존에 있어 혁신성과를 창출은 필수적이며, 가용자원이 충분하지 않은 중소기업에 있어 인적자원은 중요 요소이다. 이에 본 연구에서는 선행연구와 달리 중소기업 조직구성원의 인식을 중심으로 자기결정성과 커뮤니케이션 역량, 지식공유 및 혁신행동 간의 구조적 관계에 대해 살펴보고자 한다. [연구방법] 연구대상은 중소기업 재직자를 대상으로 실시한 402부의 설문을 바탕으로 통계분석 패키지 SPSS 21.0과 Smart PLS 2.0을 사용하여 실증 분석하였다. [연구결과] 중소기업 조직구성원의 커뮤니케이션 역량 및 지식공유에 대한 인식이 자기결정성과 혁신행동 간의 영향 관계에 대한 분석결과는 다음과 같다. 첫째, 자기결정성과 커뮤니케이션 역량은 지식공유에 긍정적인 영향을 미친다. 또한 자기결정성은 커뮤니케이션 역량에 긍정적인 영향을 미친다. 둘째, 자기결정성, 커뮤니케이션 역량, 지식공유은 혁신행동에 긍정적인 영향을 미친다. 셋째, 자기결정성과 혁신행동 간의 관계에서 커뮤니케이션 역량과 지식공유은 각각 매개효과와 함께 다중매개효과를 가지는 것으로 나타났다. [연구의 시사점] 중소기업에 있어, 커뮤니케이션 역량을 높이는 것이 조직구성원들의 혁신행동을 높이는데 효과적일 것이다. 또한 이미 커뮤니케이션 역량이 높은 기업의 경우에는 지식공유를 높이는 것은 비효과적일 것이다. [Purpose] This study examines the structural relationship between Self -Determination and Communication Competences, Knowledge Sharing, and Innovative Behavior. [Methodology] The survey was conducted on members of small and medium-sized organizations. and the sample of 402 copies was demonstrated with SPSS 21.0 and Smart PLS 2.0 [Findings] First, the results indicate that Self-Determination and Communication Competences have positive effects on Knowledge Sharing. Also, Self-Determination has positive effects on Communication Competences. Second. the results indicate that Self-Determination, Communication Competences and Knowledge Sharing have positive effects on Innovative Behavior. Third, in the relationship Self-Determination and Innovative Behavior, it was shown that Communication Competences and Knowledge Sharing had mediation and multiple mediation effects, respectively. [Implications] For small businesses, enhancing Communication Competences will be effective in enhancing the innovative behavior of the members of the organization. In addition, it would be ineffective to increase Knowledge Sharing for entities that already have high Communication Competences.

Dysplasia-associated seizure disorders are markedly resistant to pharmacological intervention. Relatively little research has been conducted studying the effects of antiepileptic drugs(AEDs) on seizure activity in a rat model of dysplasia. We have used rats exposed to methylazoxymethanol acetate(MAM) in utero, an animal model featuring nodular heterotopia, to investigate the effects of AEDs in the dysplastic brain. Pilocarpine was used to induce acute seizure in MAM-exposed and age-matched vehicle-injucted control animals. Field potential recordings were used to monitor amplitude and numbers population spikes, and paired pulse inhibition in response to stimulation of commissural pathway. Two commonly used AEDs were tested: diazepam 5, 2.5mg/kg;phenytoin 40, 60mg/kg. Diazepam(DZP) and phenytoin(PHT) reduced the amplitude of population spike in control and MAM-exposed rats. However, the amplitude of population spike was nearly eliminated in control rats as compared to the MAM-exposed rats. Pharmaco-resistance was tested by measuring seizure latencies in awake rats after pilocarpine administration(320mg/kg, i.p.) with and without pretreatment with AEDs. Pre-treatment with PHT 60 mg prolonged seizure latency in control rats, but not in MAM-exposed animals. The main findings of this study are that acute seizures initiated in MAM-exposed rats are relatively resistant to standard AEDs assessed in vivo. These data suggest that animal model with cortical dysplasia can be used to screen the effects of potential AEDs.

In this paper, we propose a contour-based motion estimation scheme. It is based on the observation that the most significant frame differences occur along moving object edges. It uses discontinuities in image brightness and frame differences to estimate displacements along edges, and avoids the difficult feature-matching problem. The proposed system transmits the contour motion information as overhead information to the receiver. But as only one motion vector per edge neighborhood needs to be transmitted, the overhead is relatively low, while achieving an impressive reduction in the motion compensated prediction error.

We discuss the theory of motion estimation and motion compensation. The proposed algorithm uses more information from the input video image sequence than the traditional two-frame pel-recursive algorithms. And it uses fewer assumptions on the motion vectors among different video frame pairs. This paper shows two three-frame pel-recursive algorithm for predictive motion compensation which can estimate the d₁(from the previous frame f_t-1 to current frame, f_t) and d₂(from the frame before the previous frame f_t-2 to the previous frame, f_t-1) simultaneously, and three frame information to update the motion vector d₁when the past motion vector d₂is available.

Nylon bag dry matter digestibility (NBDMD, %), nylon bag organic matter digestibility (NBDMD, %) and chemical compositions were analysed to evaluate the nutritive values of 5 varieties of Ca(OH)_2-treated rice straws (Akibare, Tongil, Milyang 23, Yooshin and Suwon 264) by using Korean native male goats. Three grams of dried samples by grinding with 2.45㎜ Wiley mill screen were put into a bag 9×14 ㎠ made of 100 mesh nylon. These bags were put into the ventral sac of the rumen and taken out at the end of 72 hours. They were washed, dried in an oven at 105℃ for 24 hours and weighed "NBDMD" (%) and ashed in an muffle furnace at 600℃ for 2 hours and weighed "NBOMD" (%). The results which were obtained with this experiment were as follows : 1. Nylon bag dry matter digestibility (NBDMD, %) and nylon bag organic matter digestibility (NBOMD, %) of Ca(OH)_2-treated rice straws were highly significant different (p<0.01) in different levels of Ca(OH)_2 treatment and of different varieties of rice straws. 2. The relationship between total mean NBDMD (%, Y_1) of 5 varieties of rice straws and Ca (OH)_2 concentration (%, X) at 72 hours rumen incubation was : Y_1=1.51X+41.36 (r=0.97^**) 3. The relationship between total mean NBOMD (%, Y_2) of 5 varieties of rice straws and Ca(OH)_2 concentration (%, X) at 72 hours rumen incubation was : Y_2=1.36X+41.02 (r=0.95^**) 4. The orders of NBDMD (%) and NBOMD (%) for 5 varieties of rice straws were Yooshin, Suwon 264, Milyang 23, Tongil and Akibare, and Yooshin showed the highest values and Akibare showed the lowest values. Crude fiber, cell-wall constituents and lignin percent in the five varieties of rice straws were shown the negative relation to the NBDMD (%) and NBOMD (%).

Bone destruction was induced experimentally by the insertion of a bit of the arsenic compound into the pulp chambers of the right premolars and the artificial bone defects were produced in the periapical regions of the left premolars in 7 dogs. The serial standardized periapical radiographs using aluminum stepwedge attached to the XCP instruments and resin bite blocks were taken following insertion of arsenic compound and at 2,4,7,10,14,17,21,24 and 28 days in case of bone destruction and following bone injury and weekly thereafter for a total of 14 weeks in case of bone formation. The errors of the method were determined with error estimators described by the Duinkerke. All radiographs were evaluated by the visual examination after joint evaluation by three dental radiologists and analysed with densitometer. The following results were obtained; 1. Analysis of the bone destruction process 1) The error of the method in estimating two distances proved to be small (S.D. for the measuring error; 0.04mm, S.D. for the over-all error; 0.06mm, S.D. for the positioning error; 0.05mm) 2) The radiographic changes were observed after 7 days in 6 cases, 4 days in 1 case and 10 days in 1 case by the visual examination. 3) Aluminum equivalent values were diminished after 2 days and the diminution of 0.58±0.19mm was demanded to be detected by the visual examination. 2. Analysis of the bone formation process 1) The error of the method in estimating two distances proved to be small (S.D. for the measuring error; 0.03mm, S.D. for the over-all error; 0.04mm, S.D. for the positioning error; 0.04mm) 2) The radiographic changes were observed after 2 weeks in 5 cases and 3 weeks in 2 cases by the visual examination. 3) Aluminum equivalent values were increased after 1 week and the increase of 0.45±0.15mm was demanded to be detected by the visual examination. 4) Aluminum equivalent values were increased continuously for 7 or 9 weeks but there was only extremely small change after 10 weeks.
