Objectives : This study is to investigate the hypothesis that schizophrenic patients have difficulty in inferring mental state of others. Methods : Twenty schizophrenic patients and twenty normal subjects were administered to the Cartoon Task required inferring the character's intention in a given context. Results : The schizophrenic patients showed a statistically significant impairment in the Cartoon Task. Both groups chose the card depicting a frequent everyday action significantly more rather than the similar card to the last picture in each story for wrong answers. Conclusion : These preliminary results suggest that schizophrenia is associated with a specific deficit of the cognitive ability referred to as social cognition, and this deficit can be detected not only in the acute phase as found in previous research studies, but also in remission. Also when subjects fail to appreciate what is going on in the minds of other people, they seem to rely on a socially familiar experience.

검도선수와 사격선수의 시각탐지차이에 관한 연구

권오영,김남규 한국스포츠심리학회 2004 한국스포츠심리학회지 Vol.15 No.1

본 연구는 시각탐지과제를 사용하여 주의집중의 유형이 다른 검도선수와 사격선수가 표적자극을 탐지하는데 영향을 미치는 요인을 밝혀보고 시각탐지의 차이를 알아보고자 수행되었다. 실험 모두 시각탐지과제를 사용하였으며, 표적 유형은 배경자극과 방향차원에서 차이나는 방향 표적과 세부특징에서 차이나는 세부특징 표적이었으며, 표적위치는 사사분면으로 구분하였다. 실험 1에서는 표적과 배경자극이 모두 정지되어있는 상황에서의 탐색을 다루었다. 실험 결과, 표적자극에 대한 탐지시간은 표적자극의 유형에 관계없이 사격선수가 검도선수보다 더 빠른 경향성을 보였다. 또한, 방향 표적이 세부특징 표적보다 빨리 탐지되었으며, 제1사분면에 제시된 표적이 가장 빠르게 탐지되는 위치우위성 효과를 보였다. 실험 2에서는 표적과 배경자극이 모두 운동하는 상황에서 표적의 유형과 표적위치가 탐지에 미치는 효과를 다루었다. 자극은 수직방향으로 운동하였다. 그 결과, 사격선수보다 검도선수가 표적유형에 관계없이 더 빨리 표적을 탐지하였다. 위치 우위성효과에서는 실험 1과 약간 차이가 있었다. 제1사분면과 제2사분면에서의 표적탐지가 제3사분면과 제4사분면에서의 표적탐지보다 더 빨랐다. 다가오는 자극에 대한 정체를 빨리 확인하는 것이 멀어져 가는 자극에 대한 정체를 확인하는 것보다 더 생존을 높이기 때문일 수 있다. 또한 검도선수는 세부특징 표적도 빨리 탐지하는 결과를 나타내었다. 이러한 결과는 움직임을 통한 사물지각의 중요성을 나타낸다고 볼 수 있다. This study was to investigate factors that affect the detection of a target in Gun Shooters and Kendo Masters with visual search experimental paradigm, and to compare visual detection difference between them who was different from attention type. The target was different from the background stimuli in either orientation(orientation target) or distinctive feature(feature target), and was presented in one of the four quartile positions in the Cartesian coordinates. In Experiment 1 where both the target and background stimuli were presented statically. The result of the experiment showed that the target tended to be detected faster in Gun Shooters than Kendo Masters. Also it has been discovered that orientation target was detected faster than feature target. Location priority effect was also found. That is, the targets in the first quartile position were detected faster than those in any other positions. Experiment 2 explored the effect of the target types and locations while both the target and the background stimuli were moving in vertical directions. The results showed that the target was detected faster in Kendo Masters than Gun Shooters. And the location priority effect was also found, but the effect was different in Experiment 1. That is, the targets in the first and the second quartile position were detected faster than those in any other positions. Also it has been discovered that feature target was detected as faster as orientation target in Kendo Masters. This result showed the importance of perception by the movement.

권시원,김영삼,곽규성,오상근 대한건축학회 2003 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.23 No.2

The need for this study must be considerable, as being activate for green roofs research that the organization and construction obtain access to more development technologies. Nevertheless, the green roofs system has begun to apply since 1980' s, the green roofs technology was restricted to develop without verification of technologies such as a load or water leakage. There are limit as urethane waterproofing to almost domestic waterproofing materials and methods of construction for general green roofs. The introduction of materials and methods of construction which are appropriated to property of green roofs could be a decisive factor in a long-range durability and economical maintenance cost, moreover, it support to variety construction system and organization. This present paper describes a necessity of waterproofing and root barrier system is one of the sub-organization based on green roofs construction, which have enormously large impact on the durability.

In this the study, the effects of the manufacturing process conditions on the properties Thick and Thin Diameter yarns(TTD yarns) prepared with hot plate device in the draw winder were determined. Physical properties including wet shrinkage, tenacity and elongation of the samples were measured and thick and thin effect was analysed with the evenness tester. The results were as the follows: There was little change the wet shrinkage of the TTD yarns in the range of 70°C- 80°C of R1 temperature(lower hot cylinder) with the same Hot Plate(H,P) temperature, but thc wet shrinkage of the TTIl yarns decreased 5-10% when RI temperature was 90°C. The wet shrinkage of the TTD yams decreased with the H/P temperature at the same temperature of R1, There was little effect of R1 and H/P temperature on the tenacity of TTD yarns. The elongation of TTD yarns increased with RL temperature at the same I-VP temperature. The elongation of TTD yarns increased little bit for the first time and then decreased above that temperature with increasing H/P temperature at the same R1 temper<ature. The thick and thin effect on the TTD yarns was obvious in 110°C of H/P temperature regardless of R1 temperature, while there was no thick and thin effect on the TTD yarns in 1 40°C of HiP temperature.

The current study was designed to evaluate the positive rates of arthropod allergens by Korean inhalant panel of MAST-CLA in patients with allergic rhinitis. One hundred sixty patients, diagnosed to allergic rhinitis in an Out Patient Center of Soonchunhyang University Chunan Hopsital during Aug 1998 to July 2000, were studied. 1. The overall positive rate among 35 specific allergens was 59.4% (95 patients). 2. The arthropod related allergen accounted for 82.1% (78 patients) of the positive rate. 3. Each positive rate of Dermatophagoides farinae (Df), Dermatophagoides pteronyssinus (Dp), house dust (Hd), and cockroach mix (Cm) was 45.0% (72 patients), 43.1% (69 patients), 28.1% (45 patients), and 8.8% (14 patients), respectively. 4.Significant agreement between arthropod allergens was observer (P < 0.05). 5. The obseved agreement between Df and Dp was 95.6%, showing most significant Kappa index (Kappa = 0.911, P < 0.001). There results suggested that although MAST-CLA is a useful measure of identifying specific allergens, the specificity of two mite allergen relatively low, implying because of common allergen between mites in Korean panel of MAST-CLA. Our data also supported that arthropod is the major cause of allergen in patients with allergic rhinitis, however, the MAST-CLA should be modified in order to exclude common allergen of mite and to include more specific mite allergen.

박규주,노동영,김상준,권오중,정중기,홍인규 대한화학요법학회 1990 대한화학요법학회지 Vol.8 No.2

Despite recent advances in development of antibiotics and antiseptic techniques, infection still remains to be one of the major problems in the surgical field. Due to development of bacterial resistance to commonly used antibiotics, there is always a need to develop a new antimicrobial agent which would overcome such resistance. Sulperazon (Sulbactam/Cefoperazone) is a combination drug of potent β-lactamase inhigitor, sulbactam, and cefoperazone which has broad antibacterial spectrum, which was developed to combat against β-lactamase producing microorganisms. In an effort to evaluate the efficacy and safety of sulperazone, we have randomly divided 40 patients (12 with perforated appendicitis, 10 with peritionitis, 6 with GB empyema, 6 with periproctal abscess, 3 with wound infection, 1 liver abscess, 1 pancreatic abscess, and 1 acute cholangitis) into 2 groups (20 patients in each group). One group received daily dose of 2 to 3 grams of sulperazon and the other group received daily dose of 2 to 3 grams of cefoperazone. Following results were obtained : 1. Clinical effect of sulperazon was cure in 16 patients (80%), improvement in 3 patients (15%), compaired to cure in 14 patients (70%), improvement in 4 patients (20%) for the cefoperazone group. 2. Using disc diffusion method, sulperazon was sensitive to all of the isolated microorganisms except β-hemolytic streptococci, which was moderately sensitive. Cefoperazone was sensitive to only E. coli, Pseudomonas aeruginosa and Serratia. 3. Microbiological effect of sulperazon was eradication of offending microorganisms in 16 patients (80%), compared to 14 patients (70%) in Cefoperazone group. 4. Overall clinical efficacy of sulperazon was 95%, compared to 80% for cefoperazone. 5. Adverse effects due to sulperazon was nausea and diarrhea which occurred in 1 patient respectively. 2 patients receiving cefoperazone experienced diarrhea. It can be concluded that sulperazon is a safe and effective antibiotic agent which can be used in surgical infection patients.
