The seasonal variance for estimate of exercise intensity, energy expenditure, maximal oxygen uptake and anaerobic threshold of elite women judo players(Group Ⅰ:4,Group Ⅱ: 4) was measured during 3,5,7,9,10month. The results of this study is as follows. 1. Exercise intensity by %HRmax during seasonal training was shown range of 56.45-73.62, 65.56-82.15, 80.03-86.62, 62.06-68.83%HRmax, respectiveley, from 3 to 9month in the warm up, additional exercise, main exercise and cooling down. 2. Energy expenditure per min during seasonal training was shown range of 4.09-7.96, 5.41-8.66, 8.95-9.90 and 5.05-6.41Kcal/min, respectiveley, from 3 to 9month in the warn up, additional exercise, main exercise, main exercsie and cooling down. 3. Changes of maximal oxygen uptake(VO₂max)during seasonal training and detraining not significant difference between both group, and in the seasonal variance. However, maximal heart rate during detraining expressed significant difference(p<0.05) between both group. 4. Anaerobic threshold levels during seasonal training and detraining not significant difference between both group, and in the seasonal variance. However, AT-VE(1/min) and AT- work time(min) of group Ⅱ expressed significant difference(p<0.01) in the seasonal variance.

There are many reports of the surgical management for the craniofacial abnormalities arising from the irradiation of the head and face for treatment of childhood cancers. Since the mordern combined-modality theraphy for childhood cancers began in the late 1960s and the early 1970s, recent reports have described the occular, dental and maxillo-facial abnormalities after irradiation in long-term survivors of cancers of the head and face. The resultant deformities may be known to be difficult to reconstruct with surgical techniques. This paper describes the late reconstructive surgery for the unilateral orbital and malar hypoplasia after eyeball enucleation and irradiation during childhood to correct the facial asymmetry and expand the contracted orbital socket into the functional dimension for the retaining eyeball prosthesis with spherical implant. We reports the satisfactory preliminary results from the midfacial osteotomy through the supero-lateral orbital rim and malar bone and the antero-lateral repositioning with the autogenous bone grafting in 26 year-old female patient who will be planned to make the new eyeball prosthesis by the department of ophthalmology.

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

Mo¨ssbauer 분광법을 이용한 10MnO_2-10Fe_2O_3-30Na_2O-50SiO_2 유리내의 Fe^3+ 이온에 관한 연구

We have studied the Mo¨ssbauer parameters for Fe^(3+) ion in the quenched glass and heat treated glass and heat treated glasses. The Mo¨ssbauer spectra of the quenched glass were investigated at various temperatures from 60K to 300K. Using the center shift and kinetic temperature, the Debye and einstein temperatures were calculated. The quenched glass was heat-treated at various temperatures from 530℃ to 710℃ for five hours. Both the isomer shit and quadrupole splitting parameters decreased near 590℃. And regardless of heat treatment, the Fe^(3+) ion was predominantly octahedrally coordinated.

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.

In the light of recent evidence that the abuse of inhalants is increasing among the Korean youth. A comprehensive inhalants use questionnaire was administered to a sample of 790 Kangweon provincial high school(junior and senior) seniors to determine whether or not a similar trend was evident among this students. Results indicated that 13.2% of the respondents report having tried inhalants in their lifetime, and daily use was reported by 4% among users. Somewhat higher propotions of males(15.9%) than females(10.4%), and TAT※※ high school students(17.2%) than academic high school students(12.6%) are involved in inhalants use. Inhalants users, markedly are more involved in other drugs use and they are dis-satisfied with self and their living environments. 74.0 percent of the students used inhalants for the curiosity.

Nuclear magnetic resonance(NMR) is a discipline of non-destructive radio-frequency spectroscopy ranging from physics and chemistry to biology and engineering. NMR consists of two parts; cw NMR and pulse NMR. pulse NMR is superior to cw NMR in various respects. We introduce briefly the basic theory and physical quantities of pulse NMR, and what can be known from these. The apparatus used is MSL200 for solid NMR, which is located in KOREA BASIC SCIENCE INSTITUTE SEOUL BRANCH.

This paper is an overview and a brief review of the different procedures that are available for fitting theoretical distributions to data. The use of each technique is illustrated by reference to a distribution system which including the Pearson, Johnson and Burr functions. These functions can be used to calculate percent out of specification . Accordingly, in this paper a new methods for estimating a measure of process capability for Non-normally distributed variable data proposed using the percentage nonconforming.

The optical wave interactions in a sinusoidally corrugated dielectric waveguide are analyzed for the oblique incidence case. The coupled mode equations which govern the interactions are derived by the singular perturbation method for the TE-TE mode coupling. The results are compared with those of Wagatsuma et al's normal mode analysis and stegeman et al.'s total field analysis. Phase mismatching effects to the diffraction efficiency are also investigated.

This study analyzed the variation of delay time to speed and traffic volume on various comparative and analytic methods, link construction in Daegu City's urban street as the basic data on traffic management counterplan under road construction. The delay time at the link is calculated by applying three methods of capacity analysis, shockwave theory and gueueing theory. While the result of the capacity analysis is similar to that of shockwave theory. The result of the queueing theory shows that v/c increases rapidly at 0.4 and increases slowly from 0.7 The results of comparative-analysis between the outcoming of the shockwave theory, queueing theory and capacity analysis at two or three-lane-road like and underwood value, the actual field survey outcoming are as follows : The queueing theory shows the most suitable reliability at two-lane-road and capacity analysis shows the most suitable reliability at three-lane-road.
