This study is designed to grasp the elements and situations of stage fright in order to propose a part of ways to cope with it. We make 511 top-class high school players, male and female, in the central districts (Seoul, Inchon, Kyungki, Chungbuk, and Kangweon Province) on object of questionnaire, and get the following results. Through players generally have all-round characters they show weakness in the superiority and emotional stability while showing strength in the sonformity. This fact comes to be related to the elements which cause stage fright. Physiological changes also have many effects on the symptom of stage fright. Especially, stage fright increases when players show sensitive reaction to the self-consciousness of final consequence which comes from the tension or uneasiness of sympathetic nerve, Thus, it turns out that players make use of reducing psychological burden by physical exercise or adjusting the level of demanded result in order to release the stage fright.

By the development of plant molecular biology these days which has been accomplishing much an attempt to get mutants. However, there have been haying many issues in lacking of recognition for transformants and the right of ownership of the gene. The breeding method of cell fusion without any problems can easily make new variety with an excellent character having plant itself. The purpose of this study was therefore to carry out to get trantsformants having sweeter taste and the original character of Citrus unshiu itself using PEG method of cell fusion. The yield of protoplasts per gram of leaf was 7 × 105 ~ 1 × 106/㎖ and callus cell was 1 × 106 / ㎖ . The first protoplast division and formation of micro-calli were observed 7 to 9 days and 30 to 40 days after incubation, respectively. To induce embryo from these calllus were inoculated solid medium containing 1.6% agarose and 5% sucrose. Green somatic embryo and plantlet were appeared from 1 to 2 months after plating and transfered to MT basal medium to stimulate rooting and shoot elongation. It was difficult to get normal plant directly through embryo of globular, heart and terpenoid state, and more effective method was directly to get plantlet from the globular embryo without heart and terpenoid state to control properly agar concentration.

For the comparative analysis of the blood lactate concentration of scuba diver according to change from safety zone to sea and of the change of amount of CPK while scuba diving, C university measured the blood lactate concentration and amount of CPK against middle level and debutant scuba divers. As a result, the following differences ranging from 1) to 4) were found in divers by each factor. 1) The blood lactate concentration and CPK amount of clivers out of safety zone were 2.68 and 225.70 respectively. They were out of sea area 3.70 and 337.90 respectively. The change in blood lactate concentration out of safety zone was higher than out of sea area and CPK amount was found higher from safety zone than from sea area. But to find what differences between the blood lactate concentration and CPK amount between safety zone and sea area, I implemented independent T-test against average differences, the significance of blood lactate was .092 while that of CPK amount was .312. Therefore, the blood lactate concentration and CPK amount were not significant in safety zone and sea area. In other words, there is no significant differences in change of blood lactate concentration and CPK amount of clivers in change from safety zone to sea area. 2) The average blood lactate concentration and CPK amount in 30 minutes after going out of safety zone were 2.04 and 259,80 respectively and the average blood lactate concentration and CPK amount in 30 minutes after going out of sea area zone were 2.28 and 377.60 respectively. The blood lactate concentration and CPK amount during 30-min rest after going out of safety zone were found higher in sea area. But to find what differences between the blood lactate concentration and CPK amount between safety zone and sea area in 30 minutes out of waters, I implemented independent T-test against average differences, the significance of blood lactate was .592 while that of CPK amount was .307. Therefore, the blood lactate concentration and CPK amount after 30 minutes were not significant in safety zone and sea area. In other words, there is no significant differences in change of blood lactate concentration and CPK amount of divers in change from safety zone to sea area. 3) During stabilization of divers, the average blood lactate concentration and CPK amount were 2.66 and 290.80 respectively, the average blood lactate concentration and CPK amount after going out of safety zone were 2.68 and 257.70 respectively and the average blood lactate concentration and CPK amount during 30 minutes after going out of safety zone were 2.04 and 259.80 respectively and the average blood lactate concentration and CPK amount after going out of sea area were 3.70 and 377.90 respectively and the average blood lactate concentration and CPK amount during 30 minutes after going out of sea area were 2.28 and 377.60 respectively. From the above results of higher concentration and CPK of divers going out of sea area, the sea environment gives more impact on divers. 4) The conclusion of each factor and rest is as follows: The significance of blood lactate concentration and CPK amount during stabilization and out of safety zone were .961 and .666 respectively. Therefore, there is no significance in divers resting and going out of safety zone. The significance of blood lactate concentration and CPK amount during 30 minutes of rest and out of safety zone were .083 and .683 respectively. Therefore, there is no significance during 30 minutes of divers resting and going out of safety zone. The significance of blood lactate concentration and CPK amount during stabilization and out of sea area were .035 and .514 respectively. Therefore, there is no significance in clivers resting and going out of sea area. The significance of blood lactate concentration and CPK amount during 30 minutes of rest and out of sea area were .292 and .507 respectively. Therefore, there is no significance during 30 minutes of clivers resting and going out of sea area.

Kinetic studies of nucleophilic substitution reactions of phenacyl. benzeneslfonates(PBS) with N, N-dimethyl anilines(DMA) were conducted by conductometric method. Hammett and Broensted values were determined, in order to examine the transition state variations caused by changes in nucleophiles, substituents and indicated a relatively advanced bond-formation in the transition state. Application of potential energy surface(PES) and quantum mechanical(QM) models of transition state characterization lead us to conclude that the reaction proceeds via associative S_N2 mechanism. It was found that reactivity-selectivity principle(RSP) and Bell-Evans principle(BEP) held within the DMA series and hence constituted a good example of a thermodynamically controlled reaction series but are violated between two different reaction series with DMA and aniline.

High selective and sensitive thick film type methane gas sensors were fabricated and their sensing characteristics for various hydrocarbon gases were investigated. Raw material, SnO_(2)/Au, prepared by coprecipitation was even grain size. SEM, TEM, BET and XRD analyses were carried out for investigation of surface morphology and crystalline structure. The thick film devices using the above materials exhibited high sensitivity to methane gas at the operating temperature of 400°C. The sensitivity of SnO_(2)/Au+Pd thick film devices to methane gas was higher than that to the other hydrocarbon gases such as iso-butane and propane. The optimal adding amounts of Au and Pd were 1wt.% and 3wt.%, respectively. The sensitivity, S, is defined as {(R_(A)-R_(G))/R_(A)}><100, which R_(A) and R_(G) are resistance in air and that in the gas ambient, respectively.

This study was undertaken for the clinical evaluation and statistical analysis on the 38 cases of placenta previa who were admitted and treated from March 1, 1988 to Feb. 28, 1991. The results were as follows : 1. The incidence of placenta previa was one per 53 deliveries or 1.90% 2. There were 57.9 % total placenta previa, 21.1 % partial placenta previa, 13.1 % low-lying placenta previa and 7.9% marginal placenta previa. 3. Placenta previa has occured more often in multipara (63.2%) than primigravida 4. More than one-third (38.8%) cases of placenta previa had delayed admission until labor occured for some time following vaginal spotting has first time been noticed. More instructive prenatal education should be emphasized 5. Lower segment transverse section rate was 63.2%, classical cesarean section rate was 15.8% and cesarean hysterectomy was 9.8%. The rest of them were treated by vaginal deliveries of 5 cases(13.2%) 6. The perinatal loss associated with placenta previa was considered still higher : the premature death was 15.8% and term death was 2.6%. The problem of prevention of prematurity still remains to be studied. 7. There was no maternal mortality in our study
