홍광표,권덕렬,박현아,이종무 대한금속재료학회 2003 대한금속·재료학회지 Vol.41 No.6

Transparent conducting indium tin oxide (ITO) films are deposited by rf-sputtering at a constant power of 400W in Ar atmosphere on the porous silicon (PS) layers anodized on p-type (100) Si wafers. At three successive stages of deposition for 10, 20 and 30 min. respectively, the growth of ITO on PS is thoroughly investigated by AFM, SEM and XRD techniques. The features of growth on other substrates like single crystal p-type (100) silicon, quartz and glass are also taken into consideration. The influence of ITO microstructure on the porous silicon interface is correlated with the electrical and luminescent behavior of the resulting heterojunction diode structure.

Recently there have been increasing demands for humidity-sensing elements applicable automatic humidity controlling system. There have been many reports about humidity sensors using materials such as electrolytes, organic polymers and metal oxides. Among them, those which utilize the conductivity change of metal oxides have been investigated actively. Thin film SnO_(2)/Al_(2)O_(3)/TiO_(2) devices were fabricated by evaporating the SnO_(2) powder mixed with 20.0wt% Al_(2)O_(3)and 10.0 wt% TiO_(2), and sintering them at the condition of 700℃-1hr in _(2). Analysis of FTIR indicates that water molecular act as an electron-donating gas and their chemisorption increases or decreases the electron conductivity depending on the n- or p- type. Sensing characteristics of thin film devices based on humidity-sensitive electrical properties have been investigated by response time and changes of resistance to relative humidity. Oxide filters, consisting mainly of Al_(2)O_(3) or SiO_(2) are formed on the sensors to cut off undesired sensitivity to common inflammable gases. Our experimental results suggest that metal oxide thin film can be used as humidity sensor and applicable to miniaturization and integration of sensors.

In order to play an excellent piano, it is necessary to analyze various primary element, particularly on how to use the damper pedal properly will play an important role to perform and many teachers are nicely guiding also they utilize nice performers as well. However it is considered that the guidance of utilization in a musically and artistic performance is still in short pieces. Therefore, in this thesis, analyzed centering aroung in expressing and in a musical pieces for the pedal's feature and how to use in a periodically and in a style of musical pieces. Thereby suggested on how to use the pedal in a way of musically and artistically in the future.

정신분열증 환자의 언어성 기억과제수행

전덕인,정기립,김찬형,이홍식 大韓神經精神醫學會 1998 신경정신의학 Vol.37 No.5

목 적 : 정신분열증 환자에서 기억장애가 일관되게 보고되고 있으나 반복에 의한 언어성 기억수행의 변화에 대해서는 아직도 알려진 바가 적다. 본 연구는 정신분열증 환자에서 전산화된 기억과제를 이용하여 반복시행에 따른 언어성 기억수행과 기억전략의 변화 및 학습과 망각의 양상을 정보처리적 관점에서 알아보기 위해 시행되었다. 방 법 : 항정신병약물을 7일 이상 복용하지 않은 정신분열증 환자 26명과 나이, 성, 교육정도를 맞춘 정상대조군 22명을 연구대상으로 하였다. 전산화 기억과제 중 우선 언어성 즉각 상기과제에서는 60개의 한글단어 모음에서 30개 단어가 선택되어 차례로 3초 동안 모니터에 제시된 다음, 피험자는 제시순서에 상관없이 기억나는 단어를 대답하였다. 이후 동일한 과제를 2회 반복하여 총 3회 수행하였다. 그리고 간섭과제로서 시각성 인식과제를 수행한 다음, 상기 과제를 구성하는 60개 단어모음을 하나씩 무작위로 노출시켜 앞서 보았던 단어인지 판단하는 언어성 인식과제를 수행하였다. 마지막 과제는 30분 지연 상기과제로서 언어성 즉각 상기과제에서 보았던 30개 단어를 다시 기억하여 답하도록 하였다. 항정신병약물을 7일 이상 복용하지 않은 정신분열증 환자 26명과 나이, 성, 교육정도를 맞춘 정상대조군 22명을 연구대상으로 하였다. 전산화 기억과제는 3회의 즉각 상기과제, 간섭과제, 인식과제, 그리고 30분 지연 상기과제의 순서로 시행되었다. 결 과 : 총 3회 반복된 즉각 상기과제에서 정신분열증 환자의 수행은 정상대조군보다 유의하게 떨어졌고 (df=1, F=12.4, p=0.001), 과제가 반복되면서 두 군 모두에서 유의한 수행증가가 나타났으나(df=2, F=148.0 p=0.0001) 증가되는 정도에는 차이가 있었다 (교호작용, df=2, F=11.4 . p=0.0001). 3차 상기수행과 30분 지연 상기수행의 차이(망각정도)는 정신분열증이 정상대조군보다 컸으나 유의하진 않았다. (df=33.9, t=-1.8, p=0.08), 3회의 상기수행에서는 전혀 기억하지 못했으나 지연상기에서는 기억한 단어, 즉 늦은 상기의 양은 정신분열증 환자에서 유의하게 적었다(df=46, t=3.0, p=0.005), 전체적으로 군집화 정도와 즉각상기 수행 사이에 유의한 정적 상관관계가 있었으며, 환자군의 군집화는 상기과제에서 전체적으로 정상대조군보다 감소되어 있었다(df=1, F=6.53, p=0.01), 비록 과제가 반복되면서 정상대조군과 환자군 모두 군집화가 증가되었으나(df=2, F=36.7, p=0.0001) 두 군 사이의 군집화 차이는 점점 커졌다(교호작용, df=2, F=3.72, p=0.03). 결 론 : 상기 결과에 의하면 정신분열증 환자에서는 반복에 의해 새로 학습할 수 있는 언어성 기억기능은 저하 되어 있으나 일단 학습된 기억은 유지할 수 있는 가능성이 시사되며, 이러한 학습저하에는 기억전략의 비효율성이 밀접하게 관련되어 있다고 사료된다. 정보처리적 관점에서 정신분열증의 정교한 부호화 과정의 결함을 지지하는 소견이다. Objectives : Memory deficits in patients with schizophrenia have been well established, but it is still unclear how memory performance changes during verbal learning tasks. This study was designed to assess the pattern of verbal learning and memory performance to test the inefficiency of encoding processes in learning of schizophrenia. Method : Subjects consisted of 26 patients with schizophrenia who were unmedicated for at least seven days and 22 normal controls who were matched for age, sex, and education. Verbal memory and learning were evaluated with computerized tasks composed of three consecutive immediate recall trials, a yes/no recognition test, and a delayed recall trial of a word list. Results : The patients with schizophrenia showed significant learning deficits characterized by impaired immediate recall performance and poor learning of a word list. However, both verbal recognition performance and forgetting were comparable in both groups. Word clustering correlated significantly with recall performance. Clustering of patients decreased significantly over immediate and delayed recall tasks and showed poor increase during consecutive recall tasks. Conclusion : These findings indicate that verbal learning and mnemonic strategy are impaired but learned information appears to be preserved in patients with schizophrenia The results are consistent with the notion that a learning deficit is closely related with impaired encoding processes in schizophrenia.

The central task of corporation law is to protect minority shareholders. In public corporations, the problem is refered to as the separation of ownership and control. Managers, even those who own little stock, can comtrol public companies for their own benefit rather than striving to maximize shareholder wealth. Despite efforts of legislatures, and scholars to reform corporate law, the plight of minority shareholders persist. Managers of public companies remaun free to disdain shareholders, as evidenced by the deep discount from instrinsic value at which public stocks trade. In non-public, or close, corporations the issue is referred to as the opperssion of minority shareholders. Close corparations have no market for their stock, and they rarely pay dividends. Thus, minority shares are freguently worthless to hold and impossible to sell. these conditions discourage investment and prcipitate disruptive dispute in small companies. In the search for solutions, commentators have paid remarkalbe little attention to venture capitalist supplies equity financing, but does not assume control of the enterprise. A venture capitadist protets his investment through contracts. This provides a model for protecting minority investors in close corporations. Moreover, a venture capitalist's alility to supply major equity funding rivives that private financing could eclipse the public corporation. Finally, the Article demonstrates that venture capital confirms into the strength of private equity financing ; thus, venture capital has the potential to transform corporate finance. To fully realized this potential, however, the law must change to better accomondate monority investors.

The structure-wave interactions have been studied to predict the wave fields at the coastal revetment around. The numerical modeling in the present study was based on the linear diffraction theory and boundary element approach. To investigate the interaction, the simulation has been carried out by varying the conditions of distance and length of an offshore breakwater in constant water depth. As result, various aspects of wave fields have been shown by geometric conditions of an offshore breakwater. It was found that the high waves have been significantly shown at coastal revetment around in cases of s/L=0.75 and 1.25.
