This study examined the effect of intentional thought avoidance(i.e., thought suppression and thought substitution) using "Think and No Think" task. Two syllable words were selected, and recall test was performed with a single subject group. recall accuracy of them was measured in two recall conditions(cue recall and target recall) and four training conditions(thought, thought suppression, thought substitution, and baseline). The results showed that recall accuracy in cue recall condition was better than in target recall condition, regardless of training conditions, and recall accuracy in thought condition was better than in other training conditions, regardless of recall conditions. Also there was significant interaction between recall and training conditions: For thought suppression. there was no difference between two recall conditions, whereas for thought substitution, recall accuracy in cue recall condition was better than in target condition. These findings indicate that thought avoidance strategies, including both thought suppression and thought substitution, are effective in avoiding the specific thought intentionally, and thought suppression and thought substitution could be applied by different mechanism.

대체에너지를 개발하고자 할때 반드시 고려햐야 할 사항으로는 새롭게 개발된 대체에너지가 산업의 석유의존도를 낮출 수 았어야 하고, 환경을 오염시키지 않으며, 공급이 안정되고 필요에 따라서는 언제라도 재생이 가능해야 한다. 이러한 제 조건을 충족시킬 수 있는 대체에너지로서 가장 유망한 것이 무한한 태양에너지를 생물학적 전환방법을 통해 연료화할 수 있는 바이오에너지이다. 바이오에너지란 광합성을 통해 형성된 바이오매스를 생물학적인 시스템을 이용하여 여러가지의 에너지형태로 전환시킨 것이다. 바이오매스의 생물학적 전환과정에서 가장 중요한 역할을 담당하는 것이 생태계에 널리 분포하고 있는 미생물이며 이들 미생물의 독특한 물질대사와 환경조건에 따라 다양한 형태의 바이오에너지가 얻어지는 것이다.

This study is to propose a alternative gem that is expressed in various ways instead of jewelry with limited output. It was investigated what materials were used in the alternative gem used in the jewelry design thesis over the past five years. In addition, as a result of a survey to understand the needs of customers, it was found that customers also use resin among resins as an alternative gem, like as research trends. Based on this, the scope of resin use as a alternative gem was expanded and applied to jewelry design rather than the existing method of using resin. As a result, it was found out a various uses of resin as an alternative gem. However, the demand and traditionality that correspond to the conditions of jewelry remain challenges to be established through various jewelry design studies in the future. Therefore, in order to utilize the popular preference of alternative gem, continuous research on applying jewelry design to alternative gem should be continued.

Reliability-based design optimization (RBDO) requires a high computational cost owing to its reliability analysis. A surrogate model is introduced to reduce the computational cost in RBDO. The accuracy of the reliability depends on the accuracy of the surrogate model of constraint boundaries in the surrogated-model-based RBDO. In earlier researches, constraint boundary sampling (CBS) was proposed to approximate accurately the boundaries of constraints by locating sample points on the boundaries of constraints. However, because CBS uses sample points on all constraint boundaries, it creates superfluous sample points. In this paper, efficient constraint boundary sampling (ECBS) is proposed to enhance the efficiency of CBS. ECBS uses the statistical information of a kriging surrogate model to locate sample points on or near the RBDO solution. The efficiency of ECBS is verified by mathematical examples.

As an increase in recent optical network-based IP services, GMPLS management framework becomes more important than ever before. In this paper, we propose the dynamic GMPLS path management algorithm, which can satisfy the users with their traffic engineering recovery requirements and find out the best backup service path under multiple link failures. To be more specific, we are deriving the soluble conditions of a backup path which is satisfied in a GMPLS network. In addition, through proposing the fast backup path selection algorithm, we can sufficiently satisfy a user's recovery requirement and minimally protect the suspension of the service against a link failure.

The problem of missing value imputation for variables in surveys that include item missing becomes complicated if outliers and logical boundary conditions between other survey items cannot be ignored. If there are outliers and boundaries in a variable including missing values, imputed values based on previous regression-based imputation methods are likely to be biased and not meet boundary conditions. In this paper, we approach these difficulties in imputation by combining various robust regression models and multiple imputation methods. Through a simulation study on various scenarios of outliers and boundaries, we find and discuss the optimal combination of robust regression and multiple imputation method.

We consider the estimators for the parameters of the exponential model with limited replacements under the type I censoring scheme. Also, we propose the desirable number of replacements to provide the similar effects in terms of the mean square errors.

수소화된 비정질 탄소(a-C:H)는 그 증착 조건에 따라서 여러 가지 다른 구조와 특성을 갖게 되며, 특히 DLC(diamond-like carbon) 및 CNT(Carbon nanotube)는 FED (field emission display) 개발 면에서 중요하게 연구되고 있다. 우리는 a-C:H 박막을 PECVD (plasma-enhanced chemical vapor deposition) 방법으로 증착하고 CH4 가스를 사용하였고 기판 온도는 상온-32$0^{\circ}C$ 사이에서 변화되었다. 기판은 Corning 1737 glass, quartz, Si, Ni 등을 사용하였다. 증착 압력과 R.F. power는 각각 0.1-1 Torr 와 12-60w 사이에서 변화되었다. ESR 측정은 X-band(주파수 약 9 GHz)에서 그리고 상온에서 행해졌다. 상온에서의 스핀밀도는 약한-표준피치(weak-pitch standard) 스펙트럼과 비교하여 얻을 수 있었다. 그리고 a-C:H 박막의 구조는 He-Ne laser(파장 632.8 nm)를 이용하는 micro-Raman spectroscopy로 분석하였다. 증착조건에 따른 스핀밀도의 변화 및 Raman 스펙트럼에서의 D-peak, G-peak의 위치 및 반치록, I(D)/I(G) 등을 조사하였다. 증착된 a-C:H 박막은 R.F.power가 증가할수록 대체로 스핀밀도가 증가하였으며, Raman 스펙트럼에서의 I(D)/I(G) 비율은 대체로 감소하였다. 증착된 박막들은 polymer-like Carbon으로 추정되었으며, 스핀밀도가 증가할수록 대체적으로 흑연 구조 영역이 증가됨을 알 수 있었다. 또한 glass나 Si 기판에 비해 Ni 기판위에서 polymer-like Carbon 구조는 향상되는 경향을 보였다.
