The purpose of this study is to arrange the terminology of the drawings in Chosun Dynasty, and to investigate the characteristics of drawings after the middle of Chos n Dynasty. This study is based on the and analysis of historic documents and drawings including drawings from China and Japan. In order to accomplish this, the drawings for the process of design were studied first, and the techniques of drawing were studied next in comparison with Japanese drawing techniques. Lastly, the technicians of drawing were studied. The results of this study were as follows; 1) Though the procedures of design Choson dynasty were not divided into planning, designing, construction and maintenance just like those of modern society, a variety of drawings in that time were used in each level. 2) The drawings in Choson Dynasty ere divided into Tohyong and Tosol, and mostly, those for design and construction were Tohy ng. 3) Based on the interpretation of Japanese drawings, several suggestions were presented to solve the questions of the drawing techniques for design and construction. 4) The technicians of drawing were the painters who were trained in a government organization in charge of royal paintings. In the future, research of this area should be continued in to deepen study on drawings as historical materials. This research provides meaningful of guidance in the analysis of historic drawing paintings.

The purpose of this paper is to study on the effect of cutting off tension bars in reinforced concrete beams. that is, the ultimate strength, the failure mode and thl} tension stress distribution through the span. To achieve this purpose, a full-scale frame and seven small scale model beams (five rectangular and two T-section beams) were tested. The four main model specimens and two speciml}ns without cutting off tension bars 1,'{ere analyzed as plane stmss element with package program ADINA. As a result of test and analysis, the shorter' distance bet ween the reaction point and the cutting off point, the higher the ultimate strength of a bl}am will be when other physical properties are equal.

This study has been carried out to investigate general pharmacological action of bamboo salt (jukyom) in terms of effects on central nervous system and cardiovascular system in experimental animals. After bamboo salt, crude salt or reagent-grade NaCl were orally administered into male ICR mice with dose of 2.0 g/kg, general behavioural syndromes such as body weight and locomotor activity, spontaneous motor activity, pento-barbital-induced sleeping time, muscle incoordination, electroshock-induced convulsion, body temperature and writhing response caused by 0.6% acetic acid solution were observed. Bamboo salt had no influences in these indices for examinition of effect on central nervous system. Additionally, conscious male Sprague Dawley rats fastened overnight won ere treated with bamboo salt, crude salt or reagent-grade NaCl (2.0 g/kg, p.o.) to examine the effect of these salts cardiovascular system. Systolic, median and diastolic food pressure and heart rate were dertemined using tail cuff indirect method. Treatment with Hydralazine (50 mg/kg, p.o) as a positive control produced the decreases in systolic, median and diastolic blood treasure and an increase in heart rate. whereas no changes were observed in bamboo salt, crude salt and reagent-grade NaCl treated groups. These results strongly suggest that bamboo salt may have no effects on general pharmacology of central nervous systems and cardio-vascular systems.

For the taxonomic evaluaition, 15 strains of the genus Pectobacterium and Erwinia were analyzed for 16S-23S rDNA intergenic spacer regions (ISRs). These species contained two types of ISRs, large and small ISRs. Large ISRs were on the range of 474-569 bp size, and coding transfer $\textrm{RNA}^{11e}$($\textrm{tRNA}^{11e}$) and $\textrm{tRNA}^{Ala}$. Small ISRs were 354-459 bp in length and coding $\textrm{tRNA}^{Glu}$. The sequence variations of two ISRs among species and strains were very high as compared with 16S rRNA gene sequences. By phylogenetic trees on the basis of two ISRs, Pectobacterium ere differentiated into P. carotovorum-P. cactiaidum group and P. chrysanthemi group. However, the taxonomic position of E. cypripedii and E. rhapontici, which were not clear on taxonomic delineation between Pectobacterium and Erwinia, were not clearly resolved on the basis of ISRs.

Background and Objectives : To assess the role of altered vocal function in transient voice change after short-term endotracheal intubation, we evaluated acoustic parameters, aerodynamic parameters, and laryngoscopic characteristics preoperatively and postoperatively. Materials and Methods : Vocal function of 10 patients undergoing tympanoplasty and mastoidectomy using general anesthesia and endotracheal intubation were studied preoperatively, at 1day and 7 days after extubation. Acoustic analysis, aerodynamic study, and telescopic examination were used to assess vocal function. Results : In acoustic parameters, there was no significant difference between preoperative and postoperative measures. However, in subglottic pressure, ere was a significant decrease at 1 day after extubation and this change was return to preoperative value at 7 days after extubation. MPT(Maximal Phonation Time), MER(Mean flow Ratio), and VC(Vital Capacity) were decreased 1 day after extubation but did not show statistically significant change. Three of 10 patients manifested a vocal fold edema and injection 1 day after extubation. Conclusions : Subglottic pressure revealed a significant decrease at 1 day after extubation. And this change was correlated with laryngeal morphologic change and decrement in pulmonary function.

This study attempts to measure body sizes and somatotypes of 844 female middle and high students girls in their growth period and to investigate characteristics of each of the measured somatotypes. The data used for this study were 50 items of body sizes obtained from anthropometric measurements. The purposes of the study are as follows: 1. to analyze physical characteristics according to age. 2. to extract factors of somatotypes using factor analyses. 3. to classify somatotypes according to physical characteristics using cluster analyses. The study results were as follows: 1. TH anthropometric measurements indicated that three existed collective patterns of somatotypes across Group I(12∼13 years old), Group II(14∼15 years old), and Group III(16∼18 years old). 2. Through factor analyses, 6 factors were yielded from each age group. The cumulative proportions of these factors were 77% for Group I, 75% for Group II, and 72% for Group III. Factor I indicates a horizontal size factor and Factor 2 indicates a vertical size factor. 3. Group I and Group II ere classified into 5 types and Group III was classified as 3 types. In Group I, middle height and a little slim types were most prevalent(28%). In Group II, low height and very slim types were most prevalent(28.9%). Finally, In Group III, low height and slim types were most prevalent(4.6%)

This study examined the effects of multiple recycling on deinkability and properties of recycled paper from laser computer printout (LCPO). First, alkaline paper with a 20% printed area was disintegrated by TAPPI standard disintegrator at room temperature. After dewatering, the pulp was flotated and dried in oven at80$^{\circ}C$ for 24 hrs. A sequence of wetting, disintegrating, flotating and drying was one recycling cycle and this cyclic treatment was repeated from zero to five times. The recycled handsheet dropped to 90% of the original brightness after five cycles, and lost the most brightness after five cycles, and lost the most brightness in the first two cycles. However, it had a gain of 10% in opacity after five cycles as the same as the case of nonprinting. And, in this study, the method for determining residual ink(toner) content in recycled handsheets ere established by means of SEM-EDX and Py-GC. The change of residual ink percentage on recycled paper showed the effect of recycling numbers on deinkability of waste paper. A slight decrease in deinkability was noted for the recycled handsheets, which may be due to the change of fiber surface free energy connected with fiber swelling.

The suwey on the consumption pattern of Korean traditional soy sauce and commercial soy sauce was performed. 55.8 percentage of surveyed house makes Korean traditional soy sauce domestically, But its frequency in actual use is lower than commercial soy sauce. The use of Korean traditional soy sauce and commercial soy sauce was different depending on the kinds of food. Korean traditional soy sauce is mainly used for kinds of soup, and commercial soy sauce is predominantly used for hard-boiled foods and Chapchae. Korean traditional soy sauce is known as our typical fermented food and has special flavor. But its main factors of special flavor were not well established yet. So the authors have investigated the main components of Korean traditional soy sauce for its typical taste. Five samples o$.$ere selected from'Kyung-ln'area. The sensory charac teristics of Korean traditional soy sauce itself were very different with that of cooked food added with Korean traditional soy sauce. The hard-boiled mackerel cooked with commercial soy sauce was prefered than Korean traditional soy sauce. And soups and seasoned vegetables cooked with Korean traditional soy sauce were profered. By stepwiEe regression analysis and correlation analysis, sensory overall acceptability mainly depends on specific gravity, salt content and amino nitrogen content (R'=0.94). And total nitrogen content was highly coirelated with overall acceptability (r=0.91).
