  • Purpose: This study describes the ecological variables effect on child abuse potential and the results from a prevention program for parents with disabled children aiming at decreasing child abuse potential. Method: Data was collected from 30 parents with disabled preschoolers attending an early education center in a community. The program consisted of handouts, small group lectures, support group meetings on understanding the disabled child-parents relationship, communication skill improvement, non-punitive discipline techniques, and influences of child abuse. A non equivalent pre-post test design was employed. Result: Ecological variables, and parenting self-efficacy, had a significant effect on child abuse potential in parents with a disabled child. By regression parenting self-efficacy showed(27.1 %) child abuse potential. Both parenting self-efficacy and beliefs in corporal punishment directly related to (52.0%) child abuse potential in parents. The program was effective inbringing some positive changes on pareting self-efficacy beliefs in corporal punishment, and child abuse potential toward disabled children. However, marital discord was not significantly effected. Conclusion: Child abuse prevention programs should decrease thechild abuse potential in parents. Thus I recommend a child abuse prevention program development; for parents with disabled adolescents, and teachers in disabled child education.

  • 본 연구는 이론적으로 여러 가지 임상 병리적 정신장애와 관련이 있다고 주장되어지는 내면화된 수치심이 실증적으로는 자기 통제력, 공격성, 중독가능성과 어떤 상관을 보이는지를 연구하였다. 이를 위해 자기보고에서 임상적인 문제를 호소하는 AA참가자 100명을 임상집단으로, 임상적 문제를 호소하지 않는 직장인 380명을 대상으로 내면화된 수치심 척도(ISS), 자기통제력(SCRS), 공격성 척도(BDHI), 중독가능성 척도(APS)의 설문을 실시하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 내면화된 수치심은 공격성 및 중독가능성과 유의한 정적 상관을, 자기 통제력과는 유의한 부적 상관을 나타냈다. 둘째, 각 집단 별로 자기통제력을 통제한 상태에서도 내면화된 수치심은 공격성과 중독가능성에 대해 유의미한 상관을 보인다. 셋째, 임상집단의 내면화된 수치심의 평균 점수는 비임상집단의 평균 점수보다 통계적으로 유의하게 높았다. 본 연구를 통하여 내면화된 수치심이 자기 통제력, 공격성, 중독가능성에 대해 실증적으로 유의미한 관계를 보임을 연구하였고, 마지막으로 이 연구의 제한점과 후속연구를 위한 제언을 제시하였다.

  • The stability and electrochemical properties of a self-assembled layer of spinach ferredoxin on a quartz substrate and on a highly oriented pyrolytic graphite electrode were investigated. To fabricate the ferredoxin self-assembly layer, dimyristoylphosphatidylcholine was first deposited onto a substrate for ferredoxin immobilization. Surface analysis of the ferredoxin layer was carried out by atomic force microscopy to verify the ferredoxin immobilization. To verify ferredoxin immobilization on the lipid layer and to confirm the maintenance of redox activity, absorption spectrum measurement was carried out. Finally, cyclic-voltammetry measurements were performed on the ferredoxin layers and the redox potentials were obtained. The redox potential of immobilized ferredoxin had a formal potential value of -540 mV. It is suggested that the redox-potential measurement of self-assembled ferredoxin molecules could be used to construct a biosensor and biodevice.

  • Surface potential and growth processes of hexadecanethiol (HDT) self-assembled monolayers (SAMs) on Au(111) surfaces were examined by Kelvin probe method and scanning tunneling microscopy. It was found that surface potential strongly depends on surface structure of HDT SAMs. The surface potential shift for the striped phase of HDT SAMs chemisorbed on Au(111) surface was +0.45 eV, which was nearly the same as that of the flat-lying hexadecane layer physisorbed on Au(111) surface. This result indicates that the interfacial dipole layer induced by adsorption of alkyl chains is a main contributor to the surface potential change. In the densely-packed HDT monolayer, further change of the surface potential was observed, suggesting that the dipole moment of the alkanethiol molecules is an origin of the surface potential change. These results indicate that the work function of a metal electrode can be modified by controlling the molecular orientation of an adsorbed molecule.

  • 본 논문은 3D 환경에서의 스웜시스템을 위한 자기조직화 방법을 제시한다. 스웜 시스템의 자기조직화를 위하여 인력과 척력을 이용하는 인공 포텐셜 함수(Artificial Potential Function, 이하 APF)를 사용하였다. 제안된 연구에서는 2D 환경에서 자기조직화를 위해 사용되어왔던 다양한 포텐셜들을 3D 환경에 맞게 확장 설계한다. 지면이나 수면 등의 경계면을 가지는 3D 환경의 특성을 고려하여 지면 포텐셜(Ground Potential)을 제안한다. 지면 포텐셜을 고려하지 않았을 때와 고려할 때의 비교 결과를 통해 지면 포텐셜의 필요성과 효과를 보여준다. 마지막으로, 다양한 시뮬레이션 결과를 통해 3D 환경에서 확장된 인공포텐셜과 그 성질의 효율성을 보여준다.

  • In this digest, we briefly review our current molecular dynamics (MD) simulations that utilize both the reactive empirical bond order potential (REBO) and the adaptive intermolecular REBO (AIREBO) potential energy functions. The AIREBO potential includes intermolecular interactions, so that self·assembled monolayers, and liquids, can be modeled. We have examined the mechanical and tribological properties of model self assembled monolayers and amorphous carbon films. Self-assembled monolayers are modeled by covalently bonding hydrocarbon chains to diamond substrates. Because the REBO potentials can model chemical reactions, specific compression and sliding induced chemical reactions were identified.

  • 본 논문에서는 SPICE를 사용한 16단 3D NAND Flash memory compact modeling을 제안한다. 동일한 structure와 simulation 조건에서 Down Coupling Phenomenon(DCP)과 Natural Local Self Boosting(NLSB)에 대한 channel potential을 Technology Computer Aided Design(TCAD) tool Atlas(SilvacoTM)와 SPICE로 simulation하고 분석했다. 그 결과 두 현상에 대한 TCAD와 SPICE의 channel potential이 매우 유사한 것을 확인할 수 있었다. SPICE는 netlist를 통해 소자 structure를 직관적으로 확인할 수 있다. 또한, simulation 시간이 TCAD에 비해 짧게 소요된다. 그러므로 SPICE를 이용하여 3D NAND Flash memory의 효율적인 연구를 기대할 수 있다.

  • Self-potential (SP) surveys measure naturally occurring differences in electrical potential in the absence of artificial sources and have been applied to various fields since the first application in mineral explorations. Among various causes of SP occurrences, streaming potential is generated by the flow of groundwater, and makes SP surveys suitable for the exploration of groundwater table fluctuation, fractures, sinkholes and landslide occurrences. Recently, there has been many studies that applied SP surveys to monitor water leakage through dikes and embankments. In this review paper, we first review the characteristics and theoretical backgrounds of streaming potential in saturated or unsaturated porous media to introduce it in the embankment among various application field. After the review of the background theory, we review the past cases of field SP surveys on dikes and embankments and also the characteristics of field streaming potential data in the surveys. Further, by analyzing past studies of qualitative as well as quantitative interpretation of SP survey data, we show the possibility of quantitative interpretation of streaming potential data obtained on dikes and embankments. Consequently, it is hope that this review paper helps researches on SP surveys on dikes and embankments, and provides basis for interpretation methods of the SP data to identify leaked area and further leakage rate (or permeability).

  • 대수층의 수리적 이방성 분석을 위하여 시험정이 규칙적으로 배열된 두 곳의 실험현장에 대하여 양수시험 전후에 장기간의 자연전위 모니터링을 수행하였으며, 자연전위법 적용 이전 단계에서 지표 전기비저항탐사, 노말비저항검층 및 순간수위변화시험을 이용하여 대수층의 수리지질학적 구조를 파악하였다. 최근에 제안된 수치 모델을 이용하여 두 실험현장에 대한 자연전위 모니터링 자료를 해석한 결과 피압 대수층의 특성이 나타나며, 자연전위 자료로 등전위 분포도를 작성한 결과 다양한 방법에서 얻어진 대수층의 이방성 방향과 일치됨을 확인하였다. 따라서 이 연구에서 이용된 대수층시험과 자연전위 자료의 복합해석을 이용한 이방성 분석 기법 적용 결과는 관측정이 없는 단공양수시험 시대수층의 수평적인 이방성 등을 추정하는데 유용할 것으로 판단된다.
