본 연구는 현행 전문대학 문헌정보과 교과과정을 비교 분석하여서 시대의 변화에 따라 도서관 업무도 변하고 그와 관련된 문헌정보와 교과과정도 변하는 모습을 보도록 하여 전문대학 문헌정보과 교과 과정이 이론보다 실무연습에 강조되어야 할 필요성이 있음을 알게 하는 것이다. 이렇게 하기 위해서는 도서관 현장에서 요구되는 새로운 지식을 파악하기 위한 문헌조사와 국내 전문대학 문헌정보과의 교과과정을 비교·분석하여 공통교과목을 도출하며 새로운 모형교과과정표를 작성하는 것이다.

Authors could recognize surrounding areas induding target area by the observable film density with spot radiography using Cu mask and also, radiographic images maintained high quality. Spot radiography has been utilized for a long time for the purpose of observing detail image by the control of scattered radiation. But it has been difficult to know body part in general spot radiography. Therefore it is thought that attempt to use Cu mask in spot radiography is very advantageous in a clinical examinations.

In clinical fields, single screen-film system will be generalized according to high speed and high image qualify of intensifying screen film system in future. In single screen-film system, for imaging the best image, we must choice good film according to speed and gredient. Double screen-film system will be replaced single screen film system in general radiography. Author has thought that single screen film system will be developed new diagnosis area according to X-Ray films.

This study examined well-being as a mediator between self-discrepancy and dropout intention of junior college Student. 270 students in Busan answered the questionnaire about self-discrepancy, well-being, dropout intention. Structural equation modeling indicated that there were the complete mediating effect of well-being in the relationship between self-discrepancy and dropout intention. It indicated discrepancy between individuals' representation of their actual self(their actual self-state) and their representation of individual's hopes and aspirations(their ideal self-guide) affects junior college students' dropout intention, and well-being mediate process of self-discrepancy leading to dropout intention. This conclusion provide the significant implications that help preparing psychosocial intervention strategy for junior college students to decrease dropout intention and intervention strategy to enhance their well-being.

Authors investigated the analyse trace elements in vegetables and Ginseng which indicated as follows: 1. Garlic, ginger, and onion has considerably large amounts of magnesium, garlic has in proper sequence as copper, aluminum, magnesium, bromine and mercury. Ginseng has in proper sequence as aluminum, magnesium, copper, bromine and mercury, and onion has in proper sequence as copper, manganese, aluminum, bromine and mercury. 2. Carrot has considerably large amounts of magnesium and has in proper sequence as copper, magnesium, aluminum, bromine and mercury. 3. Ginseng also has large amounts of magnesium and has in proper sequence as magnesium, aluminum, copper, bromine, and mercury.

Dendrimers represent a new class of synthetic macromolecules characterized by a regularly branched treelike structure. Peculiar features of the dendritic geometry are the large number of end groups as well as the shape persistence in higher generations, approaching spherical geometry. And one of the most peculiar characteristics of dendritic macromolecules is their controlled molecular structure and orientation, which means that they have a practical application in achieving a highly organized molecular arrangement. We attempted to fabricate a G4-48PyA dendrimer LB films containing 48 pyridinealdoxime functional end group that could form a complex structure with metal ions. Also, we investigated the surface activity of dendrimer films at air-water interface. And we have studied the electrical properties of the ultra-thin dendrimer LB films. The electrical properties of the ultra-thin dendrimer LB films were investigated by studying the current-voltage characteristics of metal/dendrimer LB films/metal (MIM) structure. And rectifying behavior of the devices was occurred in applied field.

Single screen-film systems have been used to soft tissue radiography, especially to mammo-graphy, for the Purpose of reducing patient dose, Recently, by the development of rare earth screens, they are being used to general radiography including stomach radiography. Single screen-film systems have lower speeds, but higher resolutions than double screen-film systems. And so, they can produce high image quality in oblique radiography and tomography. Authors have tested basic and physical characteristics of sigle screen-film systems, and applied them in clinical fields. Hereupon, we evaluate the sin91e rare earth screen-film systems very practicable, because they have higher speeds and higher image quality than double screen-film systems.

The purpose of the study was to estimate and analyze the rates of return to educational investment. The study was designed to estimate the social and private rates of return to educational investment by school level and sex in order to measure education's economic value with a viewpoint of human capital theory. The produced result of this study are as follows. The social rates of return to education turned out to be male high school 7.94%, male junior college 3.74%, male university 8.50% female high school 4.30%, female junior college 10.11%, female university 6.92%. The private rates of return to education turned out to be male high school 8.41%, male junior college 3.39%, male university 8.38%, female high school 7.90%, female junior college 10.34%, female university 7.33%, In order to measure economic value of educational investment, rates of return to education were compared with those to physical capital investment. Social rates of return to education turned out to be profitable for female junior college, while for private rates of return to education turned out to be profitable in all school levels except for male junior college.

We have been received questionnairs on the general characteristics and cognition of radiotechnological students, instruction which they hope, and the present processing actural states of instruction to 610 numbers of 2, 3 years radiotechnological students in korea. We have been perceived the actural states of radiotechnological instruction by the results of questionnaires, therefore, the imperfections of student's contentment, lack of instruction plan and audio-visual material's practical use, insufficient of study activities on instruction process, lack of clinical adaptation and practice of lecture evaluation were founded. We propose the solving method of these problems as the improvement of instruction. It is necessary for the will and effort of college and teacher to practices these problems.
