Objectives: The purpose of this study was to evaluate the effects of assertiveness training on assertiveness behavior, problem solving ability, and interpersonal relationships of nursing college students. Methods: A nonequivalent pre- and post-test experimental design was used. This study included 15 subjects in the experimental group, and 15 subjects in the control group, who were sophomore nursing students recruited from Gachon Nursing School located in Inchon City. The experimental group received 8 series of a ready planned and reorganized assertiveness training course, while the control group did not receive any training. The 120 minute training session was held on a weekly basis. The Maan-Whitney U Test was done to identify the changes in scores of assertiveness behavior, problem solving ability, and interpersonal relationships between the experimental and the control groups, after the assertiveness training. The data were collected before and after each part of the assertiveness training. The data collection period was from May 7 to July 10, 2001. Results: 1) The assertiveness behavior scores of the nursing students who participated in the assertiveness training were higher than those of the nursing students who did not participate in the assertiveness training. 2) The self problem solving evaluation scores of the nursing students who received assertiveness training were higher than those of the nursing students who did not receive the training. 3) The interpersonal relationship scores of the nursing students who participated in the assertiveness training were higher than those of the nursing students who did not participate in the assertiveness training. Conclusion: The study results showed that the assertiveness training was effective in promoting assertiveness behavior, problem solving ability, and changes in interpersonal relationships in nursing college students. It is suggested that well designed strategies are needed in the further studies in order to expand and apply the assertiveness training to other nursing student and nurse cohorts.

During the growing season from June to August, 2000, the soil NO and $N_2$O fluxes were measured to elucidate characteristics of soil nitrogen emissions from different types of intensively managed agricultural soils at outskirts of Kunsan City, located in the western inland of Korea, Flux measurements were made using a closed chamber technique at two different agricultural fields; one was made from upland field, and the other from rice paddy field. The flux data from upland field were collected for both the green onion and soybean field. Concentrations of NO and $N_2$O inside a flux chamber ar 15 minute sampling interval were measured to determine their soil emissions. Either polyethylene syringes of teflon air bags were used for gas samples of $N_2$O and NO. The analysis of NO and $N_2$O was made using a chemiluminesence NO analyzer and GC-ECD, respectively no later than few hours after sample collection at laboratory. The gas fluxes were varied more than one standard deviation around their means. Relatively high soil gas emissions occurred in the aftermoon for both NO and $N_2$O. A sub-peak for $N_2$O emission was observed in the morning period, but not in the case of NO. NO emissions from rice paddy field were much less than those from upland site. It seems that water layer over the rice paddy field prevents gases from escaping from the soil surface covered with were during the irrigation and acts as a sink of these gases. The NO fluxes resulted from these field experiments were compared to those from grass soil and they were found to be much higher. Diurnal and daily variations of NO and $N_2$O emission were discussed and correlated with the effects of nitrogen fertilizer application on the increase of the level of soil nitrogen availability.

The purpose of this study was to examine how horse-riding exercise would be effective on the stroke patients' muscle thickness of lower extremity. The 30 stroke patients who were hospitalized in a hospital located in G metropolitan city were selected for this study. These subjects were randomly placed in a horse-riding exercise group (n=15) and a control group (n=15). The horse-riding exercise group received three 20-minute exercises a week for a total of 6 weeks. An ultrasound imaging equipment was used to measured The thicknesses of the rectus femoris (RF), tibialis anterior (TA), medial gastrocnemius (MG), and gluteus medius (GM). After the completion of a 6-week exercise program, same measurement was conducted for all study subjects. The data were analyzed using a paired t-test and independent t-test to determine the statistical significance. As a result, muscle thickness was significantly differentiated before and after the intervention in each group. The thicknesses of all the four muscles significantly increased after exercise in the horse-riding exercise group. The thicknesses of the RF, GM, and TA significantly increased after exercise in the control group. In conclusion, horse-riding exercise increased the thickness of the lower extremity skeletal muscles by stabilizing the knees and activating the extensor muscles of the lower extremities.

Background: When we define the pressure of pulmonary vasculature in which a recruitment of blood flow occurs as $P_I$ and the proportion of change in pulmonary artery to that in cardiac output as IR and then we compare PI and IR with pulmonary vascular resistance, we would find some problems in pulmonary vascular resistance. In other words, it is the theory that, IR should be increased mainly in pulmonary embolism in which decreases the cross sectional area of pulmonary vasculature. But there are many contradictory reports resulted from various researches and the fact is known widely that any difference exists between PVR and PI, IR. For this reason, the purpose of this study is to observe how PI and IR change at the time of the outbreak and during treatment of the pulmonary embolism, and to find out the meaning of these new indicators and the difference from the pulmonary vascular resistance used generally when we subdivide the pulmonary vascular resistance into PI and IR. Method: After making AV fistula in experimental dog, we controlled cardiac output at the intervals of 15 minute in case of three kinds(all AV fistula are obstructed, only one of fistula is open and all of fistula is open), and after evoking massive pulmonary embolism with radioactive autologous blood clots, we measured the mean pulmonary artery pressure, and calculated PI and IR. We observed the pattern of change in PI and IR, without giving the control group any specific treatment and with injecting intravenously rtPA in the Group 1 and Group 2 at the dose of 1mg per kg, for 15 minutes fot the former and 3 hours for the latter. Result: 1) Pulmonary vascular resistance showed a change similar to that of pulmonary artery pressure and in all three group, PVR increased significantly, but group 1 and group 2 showed tendency that PVR keeps on decreasing after treatment, and the rate of decrease in group 1 is more rapid than group 2 significantly. 2) Both intersection(PI) and degree(IR) are proved statistically significant, in view of the straight line relationship between cardiac output and pulmonary artery pressure, calculated by minimal regression method. 3) PI changed similarly to pulmonary vascular resistance, while in the IR which is theoretically more similar to PVR, there was no significant difference or change after rtPA infusion. Conclusion: In the pulmonary embolism, Both change in IR which means real resistance of pulmonary vasculature and PI which was developed due to secondary vasoconstriction by pulmonary embolism are reflected same time.

Octagonal green glass bottle with long neck(녹유리장경각병) was found in the tomb of the princess Hwayu who was King Youngjo's daughter by a concubine while the tomb was exhumed and buried in another place around Bucheon City, Gyeonggi-do. This octagonal glass bottle is dark green. It was made in AD 1736-A1795 because it was cngraved an inscription of "건륭년제" the bottom. This glass bottle was taken an X-ray radiography and tested adhesives and restoration materials for the conservation. Loctite 401 was suitable as considering the translucency of the glass bottle, good adhesive property and reversibility of the adhesive so it was chosen. A minute piece of the glass was analyzed the composition and lead isotope ratio. Major chemical composition of the glass bottle consisted of SiO2, K2O, and PbO system and the ratio was 68: 18.5:5.7. Green color of glass bottle was due to Fe2O3 and CuO. When the glass bottle was made, quartz as raw material of silica and K2O as natural saltpeter(KNO3) were utilized. As a result of lead isotope ratio analysis, it was suggested that the galena as raw material of lead for glass making came from the southern part of China. These results are expected to become useful data in background of glass culture and circulation study of old glass.

The birth of a premature infant is distressing for its parents. The parents of a premature infant experience stress according to the infant's physical appearance and behavior, the environment of the neonatal intensive care unit (NICU) , and the alteration in the parental role. Especially, a mother of a premature infant feels distressed even after the discharge of the infant : therefore, she has difficulties in maternal role performance. The main purpose of this study is to identify the effects of the planned infant care information program in order to lower the stress level for mothers of premature infants caused by the birth and hospitalization in NICU of premature infants, to reduce the maternal role strain, and to promote the maternal role performance after the infants' discharge. This study employed two methods of research at the same time : quasi -experimental non-equivalent pre and post test to compare : non-equivalent post test to compare. The total number of subjects was 19 who were assigned to the research program : 12 mothers of premature infants at the NICU at the Ch university hospital and 7 at the NICU at the Y general hospital located in Chounju city. The data were collected for 79 days from August 18 to November 5, 1998. The questionnaire method was applied for the data collection, and the measures used in this study were Parental Stressor Scale : NICU(Miles, 1993), the Maternal Role Strain Measures ( Hobbs, 1968 ; Steffensmeier, 1982) , and Self Confidence Scale (Pharis, 1978). Research procedure is as follows : after preliminary examination, the experimental subjects, the mothers of premature infants at the Nl CU at Ch university hospital were provided with slide films and information developed by the researcher based on existing documents and data. It took two 60-minute sessions a week for two weeks, and the mothers' stress level was measured using the same instrument twice one week and two week after the infants' hospitalization. The stress level of the contrast subjects, the mothers at Y general hospital was measured during the same period. The experimental subjects were provided with booklets on matters that require attention after the infants' discharge and on developmental project, and they were educated to play the maternal role in person for 2-3 hours a week : breast-feeding, burping a baby, and changing diapers. One week after the infants' discharge, the maternal role strain and the maternal role performance were examined in two groups of the subjects. The analysis of collected data was done using descriptive statistics including real numbers, percentages, averages, and standard deviations. Mann-Whitney test ; x² test ; Repeated Measures Analysis of Variance ; ANCOVA Spearman's rho correlation coefficients. The results on this study were as follows. (1) The examination of the same quality showed that there were no differences in the general and obstetrical characters between the two groups. However, in terms of the characters of premature infants. just right after their birth, the infants at the contrast group weighed more than those at the experimental group(U=16.5, p=.02), and the former was in mother's womb longer than the latter(U=15.5, p=.02). (2) The stress level of the mothers provided with the plannned nursing intervention program became lower as time passed compared to the others'(F=16.61, p=.00) Even when the influence of weight at birth and the length of gestation was removed among the premature infants' characters, the mothers' stress levels made a statistical difference 2 weeks after the infants' hospitalization depending on treatment (F=8.00, p=.01) (3) The maternal role strain of the mothers provided with the planned nursing intervention program was lower than the others'(U=2.0, p=.00). Even when the influence of weight at birth and the length of gestation was removed among the premature infants' characters, the maternal role strain levels made a statistical difference 2 weeks after the infants' hospitalization, depending on treatment(F=14.72, p=.00). (4) The maternal role performance level of the mothers provided with the planned nursing program was higher than the others'(U=.0, p=.00). Even when the influence of weight at birth and the length of gestation was removed among the premature infants' characters, the mothers' stress levels made a statistical difference 2 weeks after the infants' hospitalization, depending on treatment(F=8.00, p=.01). (5) The correlation between a mother's stress level 2 weeks after her infant's hospitalization, the maternal role strain and the maternal role performance were compared : the stress and the maternal role strain were statistically irrelevant to each other(r=.33, p=.12) : the stress was found to be in inverse proportion to the maternal role performance(r=-.53, p=.02). The maternal role strain was in inverse proportion to the maternal role performance as well(r=-.50, p=.00). In conclusion, for the mothers provided with the planned nursing intervention program, their stress level was getting lower as time passed during the infants' hospitalization, their maternal role strain reduced when they took care of their infants after their discharge, and their maternal role performance level was high compared to the other mothers. Besides, the lower the stress level of mothers of premature infants was during the infants' hospitalization, the higher the maternal role performance after their discharge was. The lower maternal role strain was, the higher the maternal role performance was as well. These results of the study suggested that the nursing intervention program for the mothers of premature infants developed by the researcher would be effectively applied to nursing practice, and it would be a foundation for the development of this kind of program.
