The thermal decomposition process of Mo(CO)_6 on chemical vapor deposition was investigated by analyzing the effects of deposition temperature, pressure, and reaction gas on the phase change of deposited films. Mo_2C was deposited at or below 350℃ due to the incompleteness of thermal decomposition of Mo(CO)_6, but Mo films was successfully deposited at 400℃ or higher temperatures. The variation of deposition pressure did not change the dependence of decomposition process on deposition temperature. The activation energy of surface reaction was 5.8 ㎉/mole.

Those children who have mental or developmental handicaps have the rights to get education as much as the 'non-handicapped' because they are also the individuals of various personalities like the 'non-handicapped'. That means we should come up with fundamental data which helps their parents appeal their rights to proper education for their children. And that we should grope for measure which acts positively for their parents to educate their handicapped children. The focus of this study is, accordingly, to seek after the factors which influences the parents of Mental Retardation Children(MRC) or Developmental Disability Children(DDC) when they are preparing higher education for their sons and daughters. This article sets the purpose on understanding how the Problem Behaviors of the handicapped children who are under the Integrated Education and Parenting Stress of their parents affects their preparation for higher education and how Early Education and Parents Education affects. The parents of 300 of MRC and DDC from eleven cities and towns nationwide are surveyed and the result has been analyzed 01rough the statistical analysis package, SPSS ver 12.0. The followings are the result of the analysis. First, the result shows that the more the Problem Behaviors of MRC and DDC occurs, the less the parents are willing to have their children get higher education. Second, the more parents-child disfunctional interaction happens, the less tile parents are willing to have their children get higher education. Third, the more tile parents are satisfied with the effect of Early Education, the more they are willing to have their children get higher education. Fourth, the more the parents are satisfied with the programs of Parents Education, the more they are willing to have their children get higher education.

본 연구는 유체가 배관 내를 흐를 때 사용유체의 물리ㆍ화학적 성질에 따라 배관 재질이 선택된다. 소화설비에 사용하는 유체는 대부분 물을 사용하므로 물속에 용해된 각종 이물질 들은 관 벽에 스케일을 발생시키고 부식 및 배관 노후화를 촉진하여 마찰손실을 증가시켜 결국은 펌프의 효율을 저하시킨다. 설계 및 시공단계에서 마찰손실을 개선하기 위해 기존 강관대신 CPVC(Chlorinated Poly-Vinyl Chloride)배관을 이용하여 배관재질에 따라 마찰손 실 감소로 인한 소화시스템의 안정성 향상 및 경제성과의 상관관계를 고찰하였다. This investigation was materials for pipes are selected according to the physical and chemical properties of the fluid that flows within them. As water is most commonly used in fire fighting, a diversity of foreign materials dissolved in water cause scale on the walls of pipes used in fire fighting equipment. This causes erosion and pipe deterioration and increases friction losses, which leads to low efficiency of pumps. examined the correlations between economic success and improved safety of fire fighting systems thanks to decreased friction losses according to pipe materials when chlorinated poly-vinyl chloride (CPVC) was used to ameliorate friction losses compared to steel pipes in the design and construction stages.

J.S. Bach 2,3 聲 Invention의 練習曲的 價置의 硏究
鄭恩謨 漢陽大學校 人文科學大學 1988 人文論叢 Vol.16 No.-
Johann S. Bach left an exploit in 1723 by writing 30-piece set of combined two-voiced Inventions and Three voiced Sinfonia to help the exercisers of keyboard instruments in training course. The considerate composer rerealed in the preface of the work that he aimed to promote the students' technical ability in playing two or three voiced counterpoint musical operations and contabile methods for strings while developing power of musical comprehension. The work was finished by the closing stage of Cothen Age(1717-23). While the great musician completed the first collection of Welltempered Clavier he recognized the urgent necessity of exercising book for the preparatory steps. In due course, the two voiced Pracambula and Clavierbuchlein Wilhelm Friedmann and three voiced Fantasia were rewitten and reinfored for the exercising purpose. As the work was created during the foremost maturity of the composer, it successfully included every patterns found in Baroque Age Keyboard Music and counter-point techniques with no exceptions. Invention is characteristic in its operational patterns designed for developing these motive themes and in its imitation quality written for counterpoint imitation technique. It would be better described as proper form for excercise as it is equipped with broader of freer expressive function than general fuga pattern. The motive themes from Inventions provide a player with precious exercising opportunities by inducing him to experience many repititions, various application and skill promotion. Invention can be used for systematic training which one should follow step by step for the progressive exercise from scaling and saparate chords to more advanced exercise. Through this pattern, it is also possible that in multiple voiced exercise work, one finds opportunity to skill the fingers separately, for different voice development. And also through application exercise of longer melodies, one can improve in handling skill of legato or cantabile pattern. Besides these, chances to meet Baroque style decoration notes are found. It is obvious that Bach created this exercise work for the promotion of comprehensive techniques through each pieces, and that the ultimate aim of the exercise work should be explained to educate the students for perfect understanding of Bach's music as well as matured techniques.

To investigate psychopathoIogy and executive functions of attention deficit hyperactivity disorder (ADHD) children according to intelligence level, this study included 197 ADHD children who visited the outpatient department of neuropsychiatry of YeungNam University Medical Center, from July 2000 to June 2002. The children were divided into groups based on their intelligence levels. They were compared by the Personality Inventory for Children (PIC), Conncers' Continuous Performence Test (CPT), and Wisconsin Card Sorting Test (WCST). There were significant differences in PIC, on the subscales of verbal development, socialization and autism. In the CPT, there was no significant difference. In the WCST, there were significant differences in the total number of errors, the number of perseverative errors, the number of completed categories and the number of trials needed to complete the first category. Considering these results, the intelligence level of ADHD children is related to their disabilities and behavioral symptoms.Executive functions such as abstract thinking, categorization, working memory and flexibility had significant relationship to the intelligence levels of ADHD children. Therefore, the intelligence level of children with ADHD influences the higher executive functions of regulating attention and information processing rather than attentional functions and capacity alone.
