The purpose of this study was to analyze whether activity during the post-KR delay interval has an effect on motor learning. Subjects consisted of 30 male high school students, divided into interpolated activity group, predict group, control group. Acquisition phase was practiced 40 trials with KR after 1 hours from acquisition trials. The absolute error were calculated to know the accuracy of linear-positioning tasks performance by using gathered data. The two-way repeated measures ANOVA was used in order to see whether there exists significance among the groups. 1. In the acquisition stage, there apeared a significant difference at the group(P<.001) and block(P<.001). 2. In the retention stage, there appeared a significant difference at the group(P<.001) and block(P<.05). 3. In interaction effect among the factors of group, block showed no significant difference in the acquisition stage, appeared a significant difference in the retention stage(P<.01).

질화알루미늄과 금속간 계면접합에 관한 연구: 계면반응과 미세구조 형성이 접합체 강도에 미치는 영향

박성계 한국분말야금학회 1997 한국분말재료학회지 (KPMI) Vol.4 No.3

Joining of AIN ceramics to W and Cu by active-metal brazing method was tried with use of (Ag-Cu)-Ti alloy as insert-metal. Joints were produced under various conditions of temperature, holding time and Ti-content in (Ag-Cu) alloy Reaction and microstructural development in bonded interface were investigated through observation and analysis by SEM/EDS, EPMA and XRD. Joint strengths were measured by shear test. Bonded interface consists of two layers: an insert-metal layer of eutectic Ag- and Cu-rich phases and a reaction layer of TiN. Thickness of reaction layer increases with bonding temperature, holding time and Ti-content of insert-metal. It was confirmed that the growth of reaction layer is a diffusion-controlled process. Activation energy for this process was 260 KJ/mol which is lower than that for N diffusion in TiN. Maximum shear strength of 108 MPa and 72 MPa were obtained for AIN/W and AIN/Cu joints, respectively. Relationship between processing variables, joint strength and thickness of reaction layer was also explained.

활성금속브레이징법으로 계면접합된 AlN/Cu 접합체의 잔류응력 완화에 미치는 Mo 중간재의 영향을 조사하였다. 유한요소법에 의한 응력 해석과 접합체 강도 측정, 파단면의 관찰을 행하였으며, 이들 결과를 비교, 분석하였다. 응력 해석 결과로부터, Mo 중간재를 사용할 경우 최대 잔류 주응력이 형성되는 위치가 AlN/삽입금속 계면으로부터 삽임금속/Mo 계면을 통하여 Mo 내부로 이동됨을 확인하였다.접합체의 자유표면에 형성되는 인장성분의 응력집중 위치는 Mo 중간재 두께가 증가됨에 따라 Cu/Mo 계면과 Mo/AlN 계면의 두 곳으로 분리되었으며, AlN측 잔류응력의 크기는 크게 감소하였다. 중간재를 사용하지 않은 경우 최대 접합강도가 52 MPa로 낮은 강도를 보였으나, 두께 400$\mu\textrm{m}$ 이상의 Mo 중간재를 사용한 접합체의 경우, 200 MPa 이상, 최대 275 MPa의 접합강도를 얻을 수 있었다. Effect of Mo interlayer on the relaxation of residual stress in AlN/Cu pint bonded by active-metal brazing method was investigated. The stress analyses by finite-element-method, the measurement of pint strength and the observation of fracture surface were carried out and their results were compared with each other. From the results of stress analysis it is confirmed that a Mo interlayer led to a shift of maximum stress concentration site from AlN/insert-metal interface$\rightarro$ insert-metal/Mo$\rightarro$Mo interlayer. Additionally, with increase of the Mo interlayer thickness the stress concentration with tensile component was separately built both at the interface of Cu/Mo and AlN/Mo. whereby the residual stress in the free surface of AlN close to the bonded interface was drastically reduced. The AlN/Mo/Cu pints with Mo interlayer thickness of above 400$\mu\textrm{m}$ showed the strengths higher than 200 MPa. upto max. 275 MPa, while the AlN/Cu pint only max. 52 MPa.

박성계,이준희 한국스포츠산업경영학회 1999 한국스포츠산업경영학회지 Vol.4 No.2

본 연구는 소비자의 스포츠시설 이용에 따른 구매활동을 통해서 경험하게 되는 구매만족후에도 불평행동이 있을 수 있는가에 대하여 파악하고 이러한 구매만족후 불평행동의도에 대하여 인구통계변수를 이용한 조절효과를 알아보기 위하여 착수하였다. 연구의 대상은 부산시에 소재한 스포츠센터를 이용중인 성인으로서 남자 221명, 여자 222명으로 하였고, 설문조사는 자기평가입법에 따라 실시하였으며, 자료분석을 위하여 사용한 통계분석 방법은 상관관계분석, 상관계수에 대한 Fisher의 Z검증법을 사용하였다. 이상의 연구절차를 통하여 얻은 결론은 다음과 같다. 구매만족과 불평행동의도는 첫째, 인구통계변수에서 성별에서는 남자에 비하여 여자가, 연령에서는 연령이 낮을수록 높게 나타났고, 직업에서는 직장인이, 소득에서는 월 150만원에서 300만원의 소득집단이, 학력에서는 대졸집단에서 구매결과에 대하여 만족을 하면서도 불평행동을 할 가능성이 높은 것으로 나타났다. 각 집단간 상관계수의 차이에 대하여 검증한 결과 직업과 소득, 학력에서 유의한 차이가 나타났는데, 이는 이 변인들이 구매만족 후 불평행동의도에 대한 조절변수임을 알 수 있다. 따라서 이들을 이용할 경우 만족한 이용고객에 대한 불평행동의도의 조절이 가능하므로서 마케팅의 효율화를 기할 수 있는 것으로 나타났다. 둘째, 스포츠 센터를 이용하는 유형에 의한 경우에는 참가종목에서 수영을 주로 하는 집단, 스포츠센터를 이용하는 방법에서는 분기별로 등록하는 경우와 1년 이상 장기간 이용을 하는 집단에서 구매결과에 만족을 하면서도 불평행동을 할 가능성이 있는 것으로 나타났으나, 구매만족 후 불평행동의도에 대한 조절변수로서의 역할을 하지 않는 것으로 나타났다. The research on dissatisfaction action after consumer in sports facilities make satisfactory purchasing. This research is to understand whether there is complaint action after consumer make satisfactory purchasing through the use of sports facilities and it is aim that set to work to know control effect by using population statistics variable number on dissatisfaction action intend after satisfactory purchasing. The object of research is adult male 221, female 222 who are using sports center located in Pusan now, a question investigation is conducted by self-test-recording, the way of statistic analysis to analyze data is used correlation analysis. R.A Fisher's Z verification over a coefficient of correlation. The conclusion through is gained procedure of research shows that, satisfactory purchasing and dissatisfaction action intend are that First, when consider by the population statistics variable number aspect . female are higher than male in sex distinction , younger in age, about from 1.5million to 3million in income group, graduated university in academic background are showed these groups have higher the possibility do dissatisfactory action while are satisfied over the result of purchasing. The verificate result over the difference of coefficient of correlation among each groups showed that function as an regulation variable over dissatisfactory action intend after satisfactory purchasing that there is a similar gap in job, income, and academic background. In the case of using them, it is possible for satisfactory customer to regulate dissatisfactory action intend so that can make efficiencies of marketing business. Second, in the case of using type, the are swimming group mainly in lines of participation, and in the case of using sports center, groups that register by quarter and by more 1 year long-term use have a possibility to dissatisfactory action while satisfaction on the result of purchasing. But, these group showed that are not playing a part as regulate variable over dissatisfactory action intend after satisfactory purchasing.
