It is the purpose of this study to determine an effective method of communication between teachers and students. This study was done by using the theory, methods and tools of transactional analysis as developed by Borne and Harris. In order to achieve this objective: First; The teacher and student communication process is to be used, noting the student's reaction when the teacher uses "Adult" and "Parent" stimulus. Second; The effectiveness of the reaction toward the "Adult" and "Parent" stimulus is to be determined with these objectives in mind. The problems of this research study are as follows; What influence on the response of the student is brought about by the method of communication used by the teacher? 1) When the teacher uses the "Parent" Stimulus method what response of the student is shown? 2) When the teacher uses the "Adult" Stimulus method what response of the student is shown? 3) What method of communication helps to promote the student′s growth? In order to determine the answers to these questions data was collected from 40 first year students at a school of nursing in Inchon. These students were divided into two groups and the unstandardized interview technique was used to interview each student for ten minutes. A tape recording was made of each interview and the nonverbal communication was recorded by process recording immediately following each interview. The recorded material obtained from the two groups was analysed and then the Borne and Harris transactional analysis method was used in analysing the writer of this thesis undertook. Hypothesis 1. When the teacher used the "Parent" stimulus the student′s response was more frequently "Child" than "Adult", the results showed a significant difference of P〈0.001. Hypothesis 2. When the teacher used the "Adult" Stimulus the student′s response was more frequently of "Adult" than "Child", the results showed a significant difference of P〈0.001, The following conclusions are drawn from this study: 1) There is an indication that the teachers use of "Parent" stimulus communication is not an effective method to increase the growth of the student. 3) Since the teachers use of "Adult" stimulus resulted in an increase in the "Adult" response of the student there is ah indication that use of an effective communication method can help the student to develop. The writer of this research paper suggests for further study the following; 1) A comparison of the differences in response to the giving of both "Adult" and "Parent" stimulus to the same Students. 2) A comparison of the differences in student response to the communication method according to the student′s grade, age, sex and level in school.

Creep crack growth lift of high temperature pressure equipments was assessed for various crack locations and for various material properties. Surface cracks at the inner and outer surface of the vessel in the axial and circumferential directions were considered. The crack was located in the weld metal, in the parent metal or at the weld interface. Results shored that the crack at the weld interface was the most dangerous one. The crack located outside is weaker than that located inside. Safety factors of the case in which improper material properties were used the to unavailability of the correct material properties were discussed.

The progress in the field of electronic materials has been especially significant for applications involving a range of electrical properties. Its importance is increasing with the increasing demand for integrated circuits. The sol-gel technique has been used for many years, and the metal alkoxides have featured prominently as source materials. The method consist of making a homogeneous solution of the component metal alkoxides in a suitable solvent, usually the parent alcohol; and then causing the hydrolysis under controlled conditions to produce a gel containing the hydrated metal oxide. The gel is then dried, and fired to produce a ceramic or glassy material at a temperature much lower than that required by the conventional melting process. This project consists of important theoretical considerations, processing techniques and applications related to electrophoresis derived thin films. In the electrophoretic process a metal alkoxide solution is gelled through hydrolysis-polymerization and converted the gel thin layer to an oxide by heating at relatively low temperatures.

At the initial design stage, the generation process of the production material information of a building block and the simulation process of the block erection, which are required to perform the production planning and scheduling, have been manually performed using 2D drawings, based on the data of parent ships, and subjective intuition from past experience. To make these processes automatic, the accurate generation method of the production material information and the convenient simulation method of the block erection based on the initial hull structural model(3D CAD model), were developed in this study. Here, the initial hull' structural model was generated from the initial hull structural CAD system early developed by us. To evaluate the developed methods. these methods were applied to corresponding processes of a deadweight 300,OOOton VLCC. As a result. it was shown that the production material information of a building block can be accurately generated and the block erection can be conveniently simulated in the initial design stage.

This longitudinal quasi-experimental research was conducted to develop parent role education program and to evaluate the effect of this program for mother-infant interaction, childrearing environment and infant development. The subjects were the healthy infants weighing over 2,500gm at birth, whose gestational age was more than 37weeks, and their healthy mothers. The sample consisted of eighteen mother-infant dyads for intervention group and sixteen dyads for control group. Data were collected from March 15th in 1999 to Jun 20th in 2000. The intervention group received programmed education consisted of discharge education, telephone counselling, and home visiting care. But control group were collected data without programmed education. In this study, the Nursing Child Assessment Teaching Scale(NCATS) devised by Barnard was used to determine the mother-infant interaction, HOME was used to determine the childrearing environment, and Griffiths mental development scale was used to determine the infant development. The data were analyzed using SPSS Win using chi-square test, t-test, and repeated measure ANOVA. This study was focused on the results of twelve months time point. Summaries of the results were as follows: 1. There was no significant difference in mother-infant interaction(NCATS) between intervention group and control group. But both of two groups showed significantly higher in interaction score at twelve months than at six months in the subscales of social-emotional growth fostering, and responsiveness to caregiver. 2. There was no significant difference in childrearing environment(HOME) between two groups at twelve months. But when each subscale of HOME was examined, intervention group showed higher scores in the dimensions of maternal involvement with child(p=.001), and maternal emotional-verbal responsivity(p=.048). 3. There was no significant difference in GQ of the Griffiths mental development scale between two groups, although significant difference was found in performance subscale. 4. Infant development at twelve months showed significant correlation with mother-infant interaction and childrearing environment at six months, although mother-infant interaction and childrearing environment at twelve months did not show significant correlations with infant development at twelve months. 5. Developmental scores at six months showed significant correlations with variety in daily stimulation, and mother's emotional, verbal responsivity, whereas developmental scores at twelve months showed significant correlations with acceptance of child behavior at six months, and appropriate play material at twelve months. In conclusion, the maternal education program for primipara showed long term effect in some categories in organizing the childrearing environment, and fostering the infant development. We suggest further study and implications of parent role education program for high risk parents such as parents in low economic status or with premature babies.

A study was carried out to investigate the genesis and mineralogical characteristics of clay minerals in three different types of soil derived from the gray shale distributed in Kyeongbuk Province in Korea. The soils have been developed from parent materials of residuum (Daegu series, Sirye series), colluvium(Banho series), and alluvium (Bigog series) of the same origin of parent rock with a topographical sequence. The investigation mainly focussed on the mineralogical aspects of primary minerals of asnd and silt fractions, identification and quantification of clay minerals, and characterization of hydroxy-interlayered mineral (HIM) along with their chemical composition. The identification was done through analyses of chemical, X-ray diffraction, and thermal methods. The major clay minerals in the soils are illite, vermiculite, kaolin and HIM, while chlorite and mixed layer minerals such as illite/chlorite and illite/vermiculite were coexisted as a subsidiary minerals. The distribution of clay minerals, however, varies according to the location and types of parent material. In the soils derived from the parent material of residuum, the upper soil (Daegu series) shows higher of 2:1 type minerals such as illite, vermiculite, and HIM than 1:1 type mineral rich in the lower soil(Sirye series). Soils developed from the parent material of colluvium and alluvium were high in illlte and mixed layer minerals, but low in HIM compared with the residual soils. The predominant weathering sequence of the clay minerals in each soil could be inferred as follows according to the minerlogical distribution and quantification of clay minerals : Daegu series, illite ${\rightarrow}$ vermiculite ${\rightarrow}$ HIM ; Sirye series, vermiculite ${\rightarrow}$ kaolin minerals ; Banho sereies and Bigog series, illite ${\rightarrow}$ illlte/vermiculite and/or illite/chlorlte mixed layer ${\rightarrow}$ vermiculite.

In this study, tensile tests were performed on specimens that simulated the cold-bending and heat-treatment of pipe bends to understand the mechanical properties of pipe bends manufactured by cold-bending followed by heat-treatment for relieving residual stress. The strength and ductility of cold-worked materials were respectively found to be higher and lower than those of the parent material although heat-treatment was carried out to relieve residual stress. In addition, the increase in strength and decrease in ductility were proportional to the applied strain levels for cold-working. It was thus inferred that the intrados and extrados regions of pipe bends that were cold-bended and heat-treated show higher strength and lower ductility compared to the parent straight pipe and that the mechanical properties at the crown region are nearly the same as those of the parent straight pipe.

Due to the occasional occurrences of stress corrosion cracking(SCC) in steam generator tubing(Alloy 600), degraded tubes are removed from service by plugging or are repaired for re-use. Since electrodeposition inside a tube does not entail parent tube deformation, residual stress in the tube can be minimized. In this work, tube restoration via electrodeposition inside a steam generator tubing was performed after developing the following: an anode probe to be installed inside a tube, a degreasing condition to remove dirt and grease, an activation condition for surface oxide elimination, a tightly adhered strike layer forming condition between the electro forming layer and the Alloy 600 tube, and the condition for an electroforming layer. The reliability of the electrodeposited material, with a variation of material properties, was evaluated as a function of the electrodeposit position in the vertical direction of a tube using the developed anode. It has been noted that the variation of the material properties along the electrodeposit length was acceptable in a process margin. To improve the reliability of a material property, the causes of the variation occurrence were presumed, and an attempt to minimize the variation has been made. A Ni alloy electrodeposition process is suggested as a primary water stress corrosion cracking(PWSCC) mitigation method for various components, including steam generator tubes. The Ni alloy electrodeposit formed inside a tube by using the installed assembly shows proper material properties as well as an excellent SCC resistance.
