반응성 전자빔 증착 방법으로 여러 산소압력 하에서 VO$_x$ 및 V$_{1-x}$ Sn$_{x}$O$_2$박막을 유리 위에 코팅하였다. Thermochromism과 천이온도는 spectrophotometer를 이용하여 여러 온도에서 파장에 따른 광투과율을 측정하여 조사하였다. 화학양론비를 RBS로 조사한 결과 산소 압력이 5$\times$$10^{-5}$ Torr 일때 가장 뚜렷한 thermochromic 효과를 나타내는 완전에 가까운 화학양론비를 갖는 VO$_2$박막을 제작할 수 있었다. 그리고 박막의 결정화를 위하여 rapid thermal annealing (RTA) 방법을 적웅한 결과 공기중에서 40$0^{\circ}C$~45$0^{\circ}C$에서 20~30초간의 어닐링 하였을 때가 두께 100~300nm의 박막을 결정화시키는데 최적조건으로 발견되었다. 또한, Sn을 VO$_2$에 1%~6% 첨가한 V$_{1-x}$ Sn$_{x}$O$_2$박막의 써모크로미즘 및 천이온도를 spectrophotometer로 근적외선의 투과율을 측정하여 조사한 결과 뚜렷한 thermochromism은 그대로 유지되었고 V$_{1-x}$ Sn$_{x}$O$_2$, 박막의 천이온도는 VO$_2$박막의 천이온도 보다 높게 나타났다. VO$_{x}$ and V$_{1-x}$ Sn$_{x}$O$_2$thin films were fabricated on a glass under various $O_2$pressure by reactive e-beam evaporation method. Thermochromism and transition temperatures of these thin films were examined by measuring spectral solar transmittances with spectrophotometer at various temperatures, and their stoichiometries were analyzed by RBS. Oxygen pressure of 5$\times$10$^{-5}$ . Torr was found to be optimum to fabricate near stoichiometric VO$_2$thin film by reactive e-beam evaporation. Rapid thermal annealing(RTA) was adopted to crystallize the thin films and annealing at 40$0^{\circ}C$ ~45$0^{\circ}C$ for 20 ~ 30 seconds was found to be the optimum annealing condition for the crystallization of VO$_2$thin film of 100nm-300nm thickness. 1~6 atomic percent of Sn was doped into VO$_2$thin films to fabricate V$_{1-x}$ Sn$_{x}$O$_2$thin films. These V$_{1-x}$ Sn$_{x}$O$_2$thin films showed distinct thermochromism and significantly higher transition temperatures than VO$_2$thin film.

김명근(Myoung-Geun Kim),이광렬(Kwang-Ryeol Lee),은광용(Kwang-Yong Eun) 한국진공학회(ASCT) 1998 Applied Science and Convergence Technology Vol.7 No.1

13.56 ㎒를 사용하는 r.f. PACVD(plasma assisted chemical vapor deposition) 방법으로 다층 다이아몬드상 카본(DLC) 필름을 Si wafer 기판 위에 합성하였다. 다층 DLC 필름은 2.5 ㎛ 두께의 순수한 DLC 필름과 0.2 ㎛ 두께의 Si이 함유된 Si-DLC 필름으로 구성되었으며, ball on disk type의 tribometer를 이용하여 대기 중에서 다층 DLC 필름의 마모거동을 고찰하였다. 표면층으로 합성된 Si-DLC 필름내의 Si 함량이 증가함에 따라 다층 DLC 필름과 AISI 52100 steel ball 사이에 0.1 이하의 낮은 마찰계수를 유지하는 기간이 증가하였다. 44,000 cycle과 158,400 cycle의 마모실험 후 측정된 다층 DLC 필름의 마모율은 각각 2.5×10^(-8)~1.8×10^(-7) ㎣/rev.과 7.1×10^(-9)~1.8×10^(-8) ㎣/rev. 로 나타났다. 158,400 cycle의 마모실험 후 측정된 마모율은 내마모 특성이 우수한 DLC 필름보다도 2배 정도 우수한 것으로 나타났다. 마모시험에 의해 형성된 debris의 조성을 분석한 결과, 이런 낮은 마찰계수와 우수한 내마모 특성은 steel ball의 wear scar 표면을 덮고 있는 Si oxide debris 층의 형성에 따른 결과로 판단되었다. 또한, 이러한 steel ball의 wear scar 표면에 형성된 debris 층을 제거하여도, 새로운 Si oxide debris 층이 wear scar 표면에 다시 생성되어 낮은 마찰계수를 유지하고 있었다. Multi-layer diamond-like carbon (DLC) films were deposited by 13.56 ㎒ r.f. PACVD method. Multi-layer DLC film was composed of 2.5 ㎛ thick pure DLC film and 0.2 ㎛ thick Si incorporated DLC (Si-DLC) film as a surface layer. Tribological behaviors of the multi-layer DLC film were investigated with a ball-on-disk type tribometer in ambient atmosphere using AISI 52100 steel ball. Low friction coefficient (<0.1) period increased with increasing the Si content in the surface Si-DLC film. The wear rate after 44,000 cycles and 158,400 cycles were the 2.5×10^(-8)~1.8×10^(-7) ㎣/rev. and 7.1×10^(-9)~1.8×10^(-8) ㎣/rev., respectively. The wear rate of the multi-layer DLC film after 158,400 cycles was about 2 times smaller than that of pure DLC films of 2.7 ㎛ thickness. This high wear resistance and low friction coefficient was caused by the formation of Si oxide layer on the wear scar surface, as confirmed by the debris composition analysis. It was further shown that this Si oxide debris layer on the wear scar surface is formed again even after removing the debris of the steel ball, which maintain the low friction coefficient between multi-layer DLC films and steel ball.

Objectives The goal of the present study was to elucidate the characteristics of behavior problems in Sasang typology with child patients. Methods Subjects consisted of 176 (95 boys, 81 girls) children from 36 months to 83 months were diagnosed by two clinical experts in pediatrics and Sasang medicine. There were 22 So-Yang types, 141 Tae-Eum types, and 13 So-Eum types. The behavior problems were measured with Child Behavior Checklist (CBCL) and ANOVA (analysis of variance) was used for the analysis. Results There were no significant differences between Sasang types among subject's age (F(2, 173)=.190, p=.827) and sex (${\chi}^2$(2, N=176)=1.639, p=.441) as well as their mother's age (F(2, 169)=.060, p=.942) and education level (${\chi}^2$(4, N=172)=.394, p=.983) and their father's age (F(2, 168)=1.184, p=.309) and education level (${\chi}^2$(4, N=172)=5.664, p=.226). So-Yang types ($50.14{\pm}22.35$; $17.27{\pm}8.60$) had higher scores than Tae-Eum types ($38.74{\pm}21.32$; $12.62{\pm}7.98$) in total problems and internalizing problems score of the CBCL, respectively. More specifically, So-Yang types ($5.90{\pm}2.81$; $3.77{\pm}1.90$) had significantly higher depression/anxiety and somatization subscale score than Tae-Eum types ($4.04{\pm}2.73$; $2.30{\pm}2.12$). Scores of So-Yang types were significantly higher than those of CBCL clinical group in depression/anxiety and somatization subscales. Conclusions There were significant differences between child outpatients with different Sasang types, which would be taken into consideration concerning development of Sasang type diagnosis in addition to parenting, treatment, and prevention for children.

Objectives: The aim of this study was to find correlations between characteristics of Four constitution and Hwa-byung. Methods: Clinical data were collected from Hwa-byung Epidemiologic study data. we selected 130 self-labelled Hwa-byung patients data and 83 of them were diagnosed as Hwa-byung by SCID. We used Hwa-byung SCID, Hwa-byung scale, CES-D, STAI, STAXI and Personality and Physiological Symptom Questionnaire(PPSQ) as evaluation tools. We performed statistical analysis of each 2 groups, self-labelled Hwa-byung group(N=130) and diagnosed Hwa-byung group(N=83). Results: 1. In self-labelled Hwa-byung group, Greater yin score showed significant negative correlation with 3 indices of Hwa-byung scale and significant positive correlation with 1 index. Lesser yin score showed significant positive correlation with 6 indices. In diagnosed Hwa-byung group, Greater yin score showed significant negaitive correlation with 5 indices. In both groups, Lesser yang score showed no significant correlation with any indices of Hwa-byung scale. 2. In self-labelled Hwa-byung group, Greater yin score showed significant negative correlation with both trait anger score and state anger score of STAXI. Lesser yin score showed significant positive correlation with trait anxiety score, state anxiety score and CES-D score self-labelled Hwa-byung group. Lesser yang score showed significant positive correlation with anger-out score of STAXI. But Lesser yin score showed significant negative correlation with same index diagnosed Hwa-byung group. Conclusions: 1. The higher Greater yin score, suppression or denial, psychological defense mechanism, become more stronger. 2. The higher Lesser yin score, anger-out tendency become more weakened and increased prevalence of Hwa-byung symptoms. 3. The higher Lesser yang score, anger-out tendency become more stronger.
