The application of flip chip technology has been growing with the trend of miniaturization of electronic packages, especially in mobile electronics. Currently, several types of adhesive are used for flip chip bonding and these adhesives require some special properties; they must be solvent-free and fast curing and must ensure joint reliability against thermal fatigue and humidity. In this study, imidazole and its derivatives were added as curing catalysts to epoxy resin and their effects on the adhesive properties were investigated. Non-isothermal DSC analyses showed that the curing temperatures and the heat of reaction were dependent primarily on the type of catalyst. Isothermal dielectric analyses showed that the curing time was dependent on the amount of catalysts added as well as their type. The die shear strength increased with the increase of catalyst content while the Tg decreased. From this study, imidazole catalysts with low molecular weight are expected to be beneficial for snap curing and high adhesion strength for flip chip bonding applications.
PMR을 利用한 陽이온 共重合反應에서의 스티렌 및 α-메틸 스티렌의 反應性比
민경은 慶北大學校 1982 論文集 Vol.33 No.-
Styrene and α-methyl styrene copolymers were prepared in solution by cationic reaction. Proton magnetic resonance spectroscopy has applied to the analysis of monomer and copolymer compositions. Reactivity ratio of monomer was calculated from these spectroscopic data by using Kelen-Tu¨dos differential linear equation. Reactivity ratio for this system was 0.345 (r_1) and 2.389 (r_2), respectively.

This study intends to present an effective and efficient development plan about the information protection of medical institutions, by establishing the improvement plan about Personal Information Management System(PIMS) appropriate to the characteristics of medical information focusing on medical institutions generating and using domestic medical information, and doing an empirical study on medical information protection plan. For this, in view of the medical characteristics of the existing Information Security Management System(ISMS), the study presented a study model appropriated to medical institutions based on Personal Information Management Systems index specialized for personal information, and through this, presented the vulnerability diagnosis and vulnerability improvement plan. Based on ISMS index, it designed an improvement index of personal information protection management about each index. The study conducted a survey for executives and employees about PIMS. Accordingly, it presented vulnerability diagnosis items of the current management system indexes from the viewpoint of the people who establish and mange the personal information protection about patients' medical information targeting executives and employees who serve at hospitals and can access medical information.

The purpose of this study was to examine effects of foot reflexology on sleep dysfunction and fatigue in old woman. Experimental group is consisted of thirty old woman and control group is consisted of twenty-eight old woman. A research study in which a 44 minutes foot reflexology was offered on three-consecutive to experimental group from April 11, 2007 to April 18, 2007. A quasi-experimental control-group pretest-posttest design was to collect data before and after the invervention. The subject' self-report of sleep(measerd by VSH sleep scale, sleep cheek list designed by Oh et al.(1998)) and fatigue(measured by VAS, fatigue checklist designed by the Labor and health institude of japan(1998)) were recorede before and the invervention. Data analysis were consisted of frquency, percentage, mean, standard deviation, Chronbach's a, Chi-Square test, t-test, ANOVA using SPSS Win 11.0 program. 1. The first research hypothesis : Experimental group's sleep score will be higher following of foot the administration of reflexology than control group's. Experimental group's VSH score was higher following of foot the administration of reflexology than control group's(F-4.981, P=.034, F=12.654, P=001). Experimental group's sleep score was higher following of foot the administration of reflexology than control group's(F=15.945, P=.000). The first research hypothesis was supported. 2. The second research hypothesis : Experimental group's will reduce a fatigue following of foot the administration of reflexology than control group's. Experimental group's VAS score was lower following of foot the administration of reflexology than control group's(F=5.734, P=,020). Experimental group's fatigue score was lower following of foot the administration of reflexology than control group's(F=12.963, P=.001). The second research hypothesis was supported. In conclusion, foot reflexology is a effective intervention that conduced to sleep and reduces fatigue in old woman.
Poly-o-benzamide의 合成과 그의 安定性에 關한 硏究
민경은 경북대학교 공과대학 1978 工大硏究誌 Vol.7 No.-
In order to investigate the thermal stability of poly-o-benzamide, the polymer was synthesized from anthranilic acid. Although this polymer has relatively low molecular weight, it exhibits high thermal stability and excellent reistance to reagents, which have not been expected. So the synthetic route and reason of these stabilities of poly-o-benzamide have briefly been discussed.

The Purpose of this study was to determine effects of program for improving health related physical fitness developed for older people by measuring the changes in the participant's muscle strength, muscle endurance, flexiability, cardiovascular fitness. This study employed 36 healthy older people who were 60∼65 years old (mean age 62.5years). The subjects were randomly assigned to one of three gruops (two experimental groups and one control). Each group ended up with 12 subjects. The results of the study were as follows : 1. The program for improving health related physical fitness program administered to the experimental groups showed statistically significant effects with respect to the positive changes in cardiovascular fitness during the treatment period. 2. The physical fitness program administered to the experimental groups showed statistically significant effects with respect to the positive changes in flexibility. 3. The program for improving health related physical fitness program administered to the experimental groups showed statistically significant effects with respect to the positive changes in musclular endurance during the treatment period. 4. The program for improving health related physical fitness program administered to the experimental groups showed statistically significant effects with respect to the positive changes in musclular strength during the treatment period.
