윤혁민,강순주,송의호 國立 昌原大學校 産業技術硏究所 2002 産技硏論文集 Vol.16 No.-

This paper describes the implementation of FC(Frequency Converter) that can be changable voltage(2V∼250V) and frequency(40Hz∼1kHz) by DSP. This system can be using as a production or trial of Japanese or European equipment(50 Hz) as well as equipment in aerospace, ocean or military industries, operating in the special frequency over 400 Hz. As we use the TMS320LF2407A(40 MIPS) of TI company's exclusive Motion control, we have got the fastest responses and it could be possible to compose the small, low costed system with high confidence, because it includes many I/O prots and peritheral devices on a single chip.

우편집중국 수변전 설비 수용률 산정을 위한 새로운 부하 계산법 개발

윤순만,정종찬,김광호 江原大學校 産業技術硏究所 2010 産業技術硏究 Vol.30 No.A

Recently, There have been many attempts to optimize energy usage in buildings and houses using Information Technology(IT) and the typical implementation can be found in Intelligent Building and Zero Energy Building. These kinds of buildings need to forecast the building loads, estimate the capacity requirement for power supply, and decide the capacity of the main transformer of the building. Currently, the capacity of the main transformer has been decided just using typical load estimation method not considering the load characteristics and patterns. In this paper, we propose a new load estimation method considering the load characteristics and patterns of the builiding. The proposed method was applied to actual mail center and verified the feasibility of application to actual design of buildings.

We reviewed 10 years experiences of the clinical aspects and early postoperative results in 544 pediatric patients(age less than 16 years old). Among them. 529 cases had the congenital heart diseases, and 15 had the acquired diseases. Open heart surgery was performed in 413 patients. 115 cases were treated with non-open heart surgery. 16 with interventional catheterization. Annual increase of the cardiac patients was not significant in recent 10 years, except slight increase in 1994. The mean age of the study patients had been evidently changed to younger year by year. Total mortality rate of the open heart surgery was 6.4%. The cyanotic congenital heart diseases were high in early postoperative mortality by 25.7%, whereas 4% in acyanotic group. The age group less than one month was most highest in surgical mortality(66.7%). There were no deaths in patients with patent ductus arteriosus(103 cases), atrial septal defect(83 cases) or pulmonary stenosis(17 cases). Among 220 patients with ventricular septal defects(VSD). 10(4.5%) were died early postoperatively. In cyanotic group, the patients with pulmonary atresia with ventricular septal defects(PAVSD), transposition of the great arteries(TGA), interrupted aortic arch(IAA), complex cardiac anomalies with isomerism seemed to be most susceptible to an early death.

Yoon,Kyoung-Min,Hong,Soon-Kwan,Park,Cheol-Ho 한국자원식물학회 2002 Plant Resources Vol.5 No.1

Korean cultivars of buckwheat(Fagopyrum esculentum Moench.) was crossed with Canadian cultivars in order to improve seed yield as well as leaf production of buckwheat for using as food and medicine. The agronomic characteristics and rutin contents of F₂hybrids are investigated for further selection of superior lines. Dry weight per plant was the highest in a line 1110(6.71g) and leaf weight per plant was the highest in a line 1110(1.91g). Hybrid seeds were 0.55 - 0.70cm long and 0.37 - 0.47cm wide on average. 100 seeds weight ranged from 2.57g to 3.58g. Line 1076 produced the longest seeds(0.70cm) and line 1186 was the longest in seed width. Line 1196 showed the highest 100 seeds weight(3.58g). The highest frequency of the LWR(length/width rate) was 0.66~0.70, indicating that seed shape of the hybrids was mostly oval. Line 1087 showed the highest contents of rutin(77.26ppm). Lines 1090 and 1181 contained respectively rutin of 54.76ppm and 54.35ppm in the seeds. From the yield and rutin point of view, the most superior lines was line 1087 among the lines used for this study.

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 separated 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, unbalanced weightbearing, stopped movement from lying 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 viewed 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 with subjective pain score were 'stopped movement from tying position to sitting', 'limping','support with hands on sitting or standing', 'bracing', 'guarding' and 'walking with arms fixed'. In summary, although some of the 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 satisfactory. 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.

朴潤烈,金鎬順,朴柄珏 嶺南大學校附設 基礎科學硏究所 1981 基礎科學硏究 Vol.1 No.-

The interactions of various carcinogens, such as polyaromatic hydrocarbons, dimethylaminoazobenzene(DAB) and its derivatives and benzacridines with deoxyribonucleic acid(DNA) were investigated by means of second-order perturbation method. The most probable orientations of molecular complex between DNA-base pairs and carcinogen were defermined by the quantity of charge transfer from adenine-thymine pair (A=T pair) to carcinogen and from Guanine-Cytosine pair (G≡C) to carcinogen. It was found that the quantity of charge transfer from thymine part of A=T pair to carcinogen was considerably larger than that from guanine part of G≡C pair to carcinogen. A good parallelism was alos found between the quantity of charge transfer and experimenental carcinogenic activity.

The Kleine-Levin syndrome is composed of recurring episodes of sleepiness lasting days, associated with excessive appetite and often with abnormal behavior. The authors reported two cases of the Kleine-Levin syndrome. The results were as follows: 1. They were adolescent male patients. 2. The onsets were predisposed by psychological stresses of school examinations. 3. Their electroencephalograms revealed abnormal findings only during episodes of hypersomnolence. 4. One of them was improved by treatment with imipramine and lithium.
