This study was carried to investigate effects of optimum supply strengths of 'Sonneveld' nutrient solution on growth characteristics in container seedling of trees (Pinus densiflora, Torreya nucifera, Quercus acutissina and Fraxinus mandshurica) using developed media with used-rockwool. Flesh weight, height and trunk diameter in container seedling of Torreya nucifera were better in high strengths. In container seed ling of Torreya nucifera, flesh weight more increased in 1.5 and 3.0 strengths and hight and trunk diameter more increased in 1.5 strength than the rest. Flesh weight in container seedling of Quercus acutissina was heaviest in 2.0 strength and was lightest in 1.0 strength. Height and dry weight in 2.0 and 3.0 strengths and trunk diameter and total chlorophyll in 2.0 strength were better than in the rest. Besides photosynthesis rate was more high in 1.5 and 2.0 strengths than in the rest. In container seedling of Fraxinus mandshurica, flesh weight, height and trunk diameter more increased in 0.5 strength and total chlorophyll and photosynthesis rate were good in 0.5 and 2.0 strengths. Most growth characteristics were poor in 3.0 strength.

Out of the tenth graders of K girl's high school in J city, 24 students whose %fat was over 30% were divided into 3 groups through Purposing Sampling. Groups A and B were exercise groups and C was the control group. Using Borg's RPE (rating of perceived exertion), RPE 15-17 (hard-very hard) $\times$ 3 sets were set up for group A, RPE 11-13 (fairly light-somewhat hard) $\times$ 3 sets were set up for group B, and both groups performed step aerobics (step box: 68cm in length, 28cm in width, 15cm in hight, 450g in weight) for 50-60 minutes a day, 3 days a week for 8 weeks in total. This research was conducted to find out the effects of various RPE in step aerobics on the immunologic function (neutrophil, lymphocyte, monocyte, eosinophil, basophil, IgG, IgA, and IgM levels) of overweight female high school students. By using SPSS Ver. 14.0, a repeated two-way ANOVA was conducted to find out the effects of interaction between the groups and time period, paired t-test to evaluate data within each group, and pre- and post experiment difference rates (%diff) to perform one-way ANOVA for group comparisons. The following results were found. As for WBC, within group A, neutrophil, monocyte, basophil, and eosinophil levels increased, while lymphocyte levels remained the same. Within group B, eosinophil levels decreased while neutrophil, lymphocyte, monocyte, and basophil levels showed no differences. Within the control group, neutrophil, basophil, and eosinophil levels decreased while lymphocyte and monocyte levels showed no differences. As for the group comparisons, neutrophil levels increased more in group A than group B and the control group. There were no differences in lymphocyte levels among the three groups. Monocyte levels increased more in group A and B than the control group. Basophil and Eosinophil increased more in group A than group B and the control group. As for immunoglobin, within group A, the IgG level increased but the levels of IgA and IgM did not change. Within group B, the IgA level increased but the level of IgG decreased, and the level of IgM did not change. Within the control group, the IgG level decreased but the levels of IgA and IgM did not change. As for the group comparisons, the level of IgA increased more in group A than the control group, and the level of IgG increased more in group A than group B and the control group, but levels of IgM among the three groups did not show any difference. In summary, WBC and Ig levels showed that the three groups remained at the reference interval even after the exercise program. However, group A, which performed RPE 15-17 in step aerobics, showed increase in more measured items than the other groups, and this implies that the immunologic function has improved in the range of the reference intervals. Therefore, it will be effective to conduct step aerobics with the RPE 15-17 (hard-very hard) in order to increase the immunologic function.

In a trial involving 240pigs, the proximate composition, physico-chemical properites, color, amino acid composition and fatty acid composition of loin muscle were investigated in feeding various finished pig feeds. The treatments included feeding control) the low-nutrient density diet(2,960cal/kg ME, 12.25% CP, 0.41% lysine and 0.70% Ca), T1) the medium-nutrient density diet(3,220cal/kg ME, 15.50% CP, 0.87% lysine and 0.90% Ca) and T2) the hight-nutrient density diet(3,350cal/kg ME, 17.50% CP, 1.05% lysine and 0.90% Ca). The crude ash contents of T1 were significantly(p〈0.05) higher than those of control and T2. The pH$_{u}$ of T2 were significantly higher than those of control and T1, but cooking loss were significantly(p〈0.05) lower than those of control. In compositions amino acid, aspartic acid, threonine, iso-leucine and histidine of T2 were higher than those of control, but proline and glycine were significantly(p〈0.05) lower then those of control. The oleic acid(18:1) contents of control were significantly higher than those of T1 and T2, but the contents of linoleic acid(C18:2) and arachidonic(C20:4) acid were significantly(p〈0.05) lower. Inconclusion, the results of the experiments suggest that the high-nutrient density diet for pigs tended to improve the postmortem pH$_{u}$ and cooking loss.

This study analyzed consumer's harsh complaining behaviors and firm's reactions toward consumers' harsh complaining behavior, and investigated the differences in the firms' reactions according to the characteristics of counselors and customer service centers. In addition, this study attempted to find a strategy and provide guidance regarding consumer's harsh complaining behaviors. The results of this study are discussed below. First, consumer's harsh complaining attitudes were expressed by crude language, violent language, threats, personal attacks, and claims of a high-ranking social position. Consumer's directive, complaining behaviors were repeated on the telephone, and threats of prosecution or disclosure to the public, exposure of habitual product returns, and requests for interviews with superiorsat the representative firm were made. Second, a firm typologies according to its reaction style toward a consumer's harsh complaining behaviors were as follows: Group 1, having a neutral attitude toward consumers and preparation thoroughly regarding their demands; Group 2, having a negative attitude toward consumers and some degree of preparation toward consumers' demands; and finally, Group 3, having a positive attitude toward consumers but offering insufficient reparation regarding consumers' demands. Third, female counselors, counselors having a certified counselor's license, and those much experience working in labor work were more likely to be in Group 3. Male counselors, part-time counselors, and those having experience of many years were more likely to be in Group 2. Group 1 were more likely to have large number of workers at customer service centers, male counselors, and to have large numbers of educational training programs related to the reactions of consumers in the form of dissatisfaction, complaints, how to offer compensation for injuries to consumers, and issues related to PL(product liability). In addition, Group 1 also had more firm level welfare policies related to hight stress levels of consumer counselors and extra types of support regarding harsh consumers. However, Group 2 members were more likely to provide excessive compensation and rewards to harsh consumers. Finally, to react to consumer's harsh complaint efficiently, it was suggested that firms should not treat consumers as harsh consumers, should react to consumers' complaints sincerely, and should take precautionary management efforts as regards consumer dissatisfaction based on better quality control of products. In addition, it was deemed necessary to formulate a management strategy to train competent consumer counselors with a high quality of counselor skill, having standardized and consistent reaction guidance toward consumer complaints and thorough knowledge of compensation rules for consumer injuries and subsequent guidance.

The purpose of this study was to examine the reliability and validity of the observed behaviors of subjects who suffered from low back pain with spinal diseases, Thirty two low back pain patients admitted on the neurosurgical unit in an army hospital were compared with 30 normal controls belonged to an army unit, by means of matching the age, hight and weight. Observed pain behaviors were developed by the researcher on the bases of literature and patient observation. This tool consists of 18 behaviors seperated into two major groups : mutually exclusive and concomittent behaviors. The mutually exclusive behaviors included coding cathegories for 6. body motions assumed by the subjects during the observation session. These 6 standardized motions consisted of sitting from standing first, and serially tying down, reclining, sitting again, and then standing, 6 steps walking. Concomittent behaviors consisted of 12 observable patterns that can be observed systematically from the face, grimacing, bracing, rubbing, walking with arms fixed, support with hands on sitting or standing, guarded movement, limping, unbalaced weightbearing, stopped movement from tying position to sitting, sighing and graoning. Subjects were videotrecorded as they performed a 6-standardized sequence of motions, simultanously researcher measured the time spent performing each motion and step length. Patients were asked torate their subjective pain score on the 10 mm graphic rating scale ranging from 'no pain' to 'sever pain'. For scoring of the pain behaviors, two trained nursing officiers independently and simutanously viewwd each videorecording and checked subject 'pain behaviors at the observational item checklist. The result of the study are summarized as follows : 1. Reability of the observational tool was a=.845. 2. Spearman's rho and percentage agreement were p=.97 and 81.7 persent respectively, that indicate adequate interrater reability of this tool. 3. The sensitivity rate of the tool was .875 while specificity rate .866 for differentiating patient from the normal. 4. When difference in the objective pain indices between patient group and control were compared, there was significant difference of all indices, such as pain behavior(t=7.71, p=.0001). spent time performing motion(t=14.2, p=.0001), step length (t=-10.72, p=.0001). 5. There were differences in the objective indices the subjective pain subgroups (low, medium, high). Differences in the mean score of objective pain behavior (F=6.376. p=.005) and spent time for moyion(F=4.631, p=.018). But there were no significant differences in the step length among the subgroups(F=.667, p=.521). 6. Highly correlated pain behavior items wiyh subjective pain score were 'stopped movement from lying position to sitting', 'limping', 'support with hands on sitting or standing', 'bracing', 'guarding' and 'walking with arms fixed'. In summary, although some of rho behavior items such as sighing and groaning in this study could not be observed because of videotaped datd, the reliability and validity of the over all observation method were satifactory. Thus, the results of the present study demonstrate rye potetional utility of the tool in assessing objective pain complementing self-reported pain in low back pain patients.

This study was conducted to find out the effect of rice straw and wollastonite applied to the paddy soil on the growth and yield of the rice plant. The soil was treated with two level of straw 0 and 88gr per pot, of which respectively combined with 4 levels of wollastonite, 0 (Avail $SiO_2$: 50 ppm), 27 (Avail. $SiO_2$: 150 ppm), 85 (Avail. $SiO_2$: 300 ppm) and 185 (Avail. $SiO_2$: 450 ppm) gr per pot. The results for two years experiment were as follows. 1. Application of rice straw and wollastonite, respectively, suppressed the growth of the plant at early stage. As a consequence the hight and number of tiller of the plant were comparatively smaller, but the combined effect of rice straw and wollastonite treatment on the plant growth appeared after the maximum tillering stage and got a better yield as compared with single treatment of rice straw or wollastonite. 2. At the pot of no rice straw and 27 gr wollastonite treatment, and also pot of rice straw and 85gr (in the year of 1983 experiment) as well as 135gr wollastonite treatment (in the year 1984 experiment), the yield of total dry material and unhulled rice of the plant were respectively higher than other pots in different treatment and the plant height showed similar tentency. Application of rice straw in paddy soil appeared to require more wollastonite for growth of the rice plant as compared with no rice straw application. 3. The highest yield was obtained at the pot with rice straw and 85gr of wollastonite treatment in the year of 1983 experiment, were its yield had 25% increament as compared with the control pot, while being studied for residual effect of rice straw and wollastonite application in the next year, the highest yield was obtained at the pot with rice straw and 135gr wollastonite treatment, where its yield had 30% increament as compared with the control pot.

This experiment was conducted to investigate the effects of dietary supplementation of oriental herb extracts (Alpha $Plus^{(R)}$ (AP)+Dried Foxglove Powder (DFP)) on growth performance and proliferation of splenocytes in broiler chicken raised under low or high density stocking conditions. A total of 240 male broiler chicks were randomly divided into four treatment groups with three replicates composed of ten birds in low density stocking groups and thirty birds in high density stocking groups. The four treatment groups were as follows: Cl (low density without AP and DFP); T1 (low density with AP 0.2% and DFP 0.03%); C2 (high density without AP and DFP); T2 (high density with AP 0.2% and DFP 0.03%). The feed intake of the high density stocking group was significantly lower than that of low density stocking groups during overall experimental period (p<0.05). The body weight of high density stocking groups was lower than that of low density stocking groups (p<0.05). The decrease of feed intake and body weight gain in growing stage (7~25day) under the high density stocking condition seems to be recovered in final stage (26~34day). Meanwhile dietary supplementation of AP+DFP in low and high density stocking groups tended to have higher daily body weight gain than control groups. The proliferation of splenocytes in treatment groups was significantly higher than control groups (p<0.05). In conclusion, the result of the present study suggested that the oriental herb extracts (AP+DFP) could be used as an alternative feed additive resources to improve growth performance and immune activity in broiler chickens.

The various oriental herbal medicines, which have usually been used for treatment of reducing fever, purging intense heat and detoxication, were screened to determine the antibacterial activity and the minimal inhibitory concentration against pulmonary disease-causing Klebsiella pneumoniae, Streptococcus pyogenes, and Streptococcus pneumoniae. The results obtained were as follows: 1. Among the 23 oriental medicines tested, the water-soluble extracts of Coptis japonica, Scutellaria baicalensis and Picrorrhiza kurrooa showed the antibacterial activity against K.pneumoniae and that of C. japonica against S. pyogenes. The antibacterial activities of C. japonica, Prunusmume, Schizandra chinesis, Scutellaria baicalensis were also found against S.pneumoniae. When C.japonica was used, the high antibacterial activity was shown against Bacillus subtilis and other extracts showed a little activity against B. subtilis and E. coli as a control. 2. The ethanol-soluble extracts of Patrinia scabriosaefolia, P. mume, S. baicalensis, S. chinesis showed the antibacterial activity against K. pneumoniae and those of S. baicalensis, C. japonica, S. chinesis, P. mume agaist S. pyogenes and S. pnuemoniae. However, those extract showed a little antibacterial activity against B. subtilis and E. coli except for that the extract of C. japonica showed comparatively high growth inhibition of B. subtilis. 3. Among the medicinal herbs tested, the water and ethanol extrats of C. japonica showed very extcellent antibacterial activity against the pathogenic bacteria and controls. 4. When the water-soluble extracts of C. japonica and S. baicalensis, minimal inhibitory concentrations (MICs) against K. pneumoniae were $10mg/m{\ell}$ and $22 mg/m{\ell}$, respectively. The MICs of the ethanol-soluble extracts of P. mume and P. scabriosaefolia were $5mg/m{\ell}$ and $20mg/m{\ell}$, respectively. 5. For the MICs against S.pyogenes, C. japonica showed $15mg/m{\ell}$ with the water-soluble extract and P. mume and C. japonica with the ethanol-souble extract did $5mg/m{\ell}$ and $10mg/m{\ell}$, respectively. 6. For the MICs against S. pneumoniae, C. japonica and P. mume with the water- and ethanol-souble extract showed $5mg/m{\ell}$ and $10mg/m{\ell}$, respectively. As a result, the highest antibacterial activity was found in the water- and ethanol-soluble extracts of C. japonica against pulmonary disease-causing bacteria, K. pneumoniae, S. pyogenes. and S. pnuemoniae. Also, the water- and ethanol-soluble extracts of S.chinesis. P.mume, S.baicalensis, and P.kurrooa showed hight antibacterial activities.
