본 연구는 유아의 사회적 능력 수준에 따른 창의성의 변화를 비교하기 위하여 T광역시 소재 유치원의 만 4세 유아 147명을 대상으로, 우수경(2002)의 유아 사회적 능력 검사와 전경원(2001)의 유아 도형 창의성 검사를 실시하였다. 연구 결과, 첫 째, 사회적 능력이 높은 유아들이 낮은 유아들보다 창의성이 높은 것으로 나타났다. 그리고 사회적 능력과 창의성 측정 시기 간에 상호작용 효과가 있는 것으로 나타나, 사회적 능력이 높은 유아들의 창의성은 측정 시기마다 점점 증가한 반면, 사회적 능 력이 낮은 유아들은 창의성이 증가했다가 다시 감소하였다. 둘째, 창의성 하위요인별 로 볼 때, 유창성, 독창성, 개방성은 사회적 능력에 따라 차이가 있으나, 민감성은 차 이가 없었다. 그리고 창의성 하위요인 중 독창성은 사회적 능력과 독창성의 측정 시 기 간에 상호작용 효과가 있는 것으로 나타나, 사회적 능력이 높은 유아들의 독창성 은 측정 시기마다 점점 증가한 반면, 사회적 능력이 낮은 유아들은 독창성이 증가했 다가 다시 감소하였다. This study investigates the relationships change process between young children``s creativity and social competence. Participants consist of 147 kindergarten children in T-city. The instruments are Woo``s(2002) Children``s Social Competence Scale and Chon``s(2001) the Korean Figural Creativity Test for Young Children. The main findings of this study are as follows. First, a child’s creativity differs according to the child’s level of social competence. Children displaying high social competence demonstrate, as time goes by, increased creativity. Second, a child’s fluency, originality, and openness differ according to the child’s level of social competence, though no difference is observed regarding sensitivity. An interaction effect is found in originality and social competence such that a high level of social competence is associated, as time goes by, with an increase in originality.

텅스텐인산으로 개질된 SBA-15 촉매 상에서 아세트산의 탈수반응

우창수,He, Nong-Yue,김현국,이호인 한국공업화학회 2004 응용화학 Vol.8 No.1

TPA (tungstophosphoric acid), a typical heteropoly acid, was impregnated on SBA-15 to modify the acidic property of the mesoporous catalyst. The TPA was highly dispersed on the SBA-15 which has large surface area confirming by nitrogen adsorption, X-ray diffraction, and infrared spectroscopy. According to the result of in-situ FTIR spectroscopy using pyridine as a probe molecule, it was revealed that silanol group was gradually decreased with increasing the loading amount of TPA, and that new acidic site different from that of pure TPA was generated resulting in the enhancement of catalytic activity. TPA could act as a promoter when loaded on SBA-15 by relatively small amount, but the catalytic activity was greatly decreased due to the loss of silanol group as an active site when a large amount of TPA was loaded.

본 논문은 Distance 합성알고리즘과 Runlength-Distance 합성알고리즘을 이용하여 효율적으로 문서화상을 합성하기 위한 방법을 제안한다. 데이터 또는 문서의 화소정보를 비밀리에 화상에 혼합하는 합성 알고리즘에는 임 Runlength 합성알고리즘(RM), Distance 합성알고리즘(DM), Runlength-Distance 합성알고리즘(RDM)등이 제안되었다. 그러나 이러한 합성알고리즘들을 적용한 기존의 방법은 암호화 시간이 길어지고 신뢰도가 떨어지는 문제점을 갖는다. 본 논문에서는 DM과 RDM 알고리즘을 보다 효율적으로 적용하여 암호화 시간을 단축시켰다. 또한, 기존 합성알고리즘에서의 합성방법을 변형한 형태로서 모듈별로 디지털 서명을 합성하는 방법을 제안한다. 이렇게 모듈별로 디지털 서명을 가함으로써 보안 전송에 있어서 가장 중요한 요소인 신뢰도를 증가시키도록 하였다. Runlength Mixing(RM), Distance Mixing(DM) and Runlength-Distance Mixing(RDM) algorithms have been proposed for mixing of bits of document-images security. However the existing mixing algorithms have some problems that increase cryptographic time and reduce confidence. In this paper, we propose an algorithm for mixing document images efficiently by using DM and RDM. When we mix digital signatures and secure documents, by using DM the proposed algorithm reduces the encryption time of document images. In addition the proposed algorithm mixes digital signatures by each module in order to increase confidence. It is shown through the experiments that our algorithm outperforms the existing mixing algorithms in terms of encryption time and confidence.

Fingerprint patterns of 333 schizophreniacs who met with the diagnostic criterias of International Pilot Study of Schizophrenia except items associated with chronicity in exclusion criteria were studied, and the following results were obtained. 1. The frequency distribution of the fingerprint patterns in the 333 schizophreniacs was ulnar loop, whorl, twinned loop, arch, radial loop in order in both control and schizophrenia groups. 2. Finger ridge counts of both sexes were decreased significantly in schizophrenia group. 3. Dissociation of fingerprint pattern in the schizophrenia group was 51.1%, which was far greater than 6.25% of control group. Number of dissociation was greatest in the thumb, followed by index, middle, ring, and little finger in order. According to the above results, it is considered that both the number of finger ridges and degree of dissociation of fingerprint patterns were closely related with schizophrenia. Analysis of fingerprints and palmprints with the aid of chromosomal analysis would contribute the early diagnosis and prevention of schizophrenia.

Catalytic dehydration of acetic acid was performed over surface-modified MCM-41. Calcination of silylated MCM-41 under air regenerated successfully silanol groups as the active sites for dehydration of acetic acid. In-situ FTIR spectroscopy using pyridine as a probe molecule revealed that as the pretreatment temperature before silylation increased, the concentration of Lewis-acidic sites was enhanced. The enhanced concentration of Lewis-acidic sites augmented the bridged adsorption species of acetic acid on the surface of the modified catalyst, which significantly promoted the catalytic activity.

Diabetic Nephropathy is one of the major causes of chronic renal failure. It is a common microvascular complication and clinically defined as the presence of persistent Proteinuria. We studied the effects and change of the renal function of Complex Herbal medication of the 20Diabetic Nephropathy patients. We measured the initial levels of Total Protein, Creatinine Clearance Rate(Ccr), Serum Creatinine(Serum-Cr), Urine Creatinine(Urine-Cr) and HbA1C on admission and followed up the level changes of Total Protein, Ccr, Serum-Cr and Urine-Cr on discharge. The results are following : Complex Herbal Medication does not cause the renal toxicity. The longer hypertension period is, the higher Serum-Cr level and Urine-Cr level. In an older age group, Urine-Cr is lower. 4.From the "Deficiency in Origin and Excess in Superficiality(本虛表實)“points of view, Complex Herbal Medication improves the Serum-Cr in Diabetic Nephropathy patients. According to this results, it could be suggested that Complex Herbal Medication does not cause the renal toxicity in Diabetic Nephropathy patients and intensive controls of blood sugar, blood pressure and Complex Herbal Medication prevent the renal failure in Diabetic Nephropathy patients with early stage of Microalbumiuria.
