김재우,정현도 한국기술교육대학교 2006 論文集 Vol.13 No.1
The purpose of this study were to investigate the real recreation activity state of Taekwondo players in middle school, provide better way and basic material on the method for improving contest ability mental and mind health and sound recreation. The sampling of this study was middle and high schools' Taekwondo players who participated in the Taekwondo contest of chungnan province. Sample size was 200 persons and 178 questionnaire were used for analyzing. Contents of questionnaire were made of 24 articles : backgrounds of players(3), general factors of recreation(4), recreation time(5), the types of recreation and satisfaction degree(4), recreation facility and their needs(3), recreation activity in the school(3), education on the recreation and other things(2). Cross tab was used as an analytic method which investigate the difference of respondents' background. The statistical program was SPSS. Results of this study and discussions were separately presented : backgrounds of respondents, path of information acquiring on the recreation activity, the plan of recreation activity, recreation participation time of the week, recreation activity times of the week, recreation participation time of Saturday, recreation activity times of Saturday, recreation participation time of Sunday, recreation activity times of Sunday, the type of recreation activity, mainly using facility in recreation activity, the type of recreation activity in the school, priority problem to provide better recreation activity. As a conclusion, three conclusion were presented. First, the policies which protects and promotes women's players should supplement. Second, to acquire information on the recreation activity, the education in the schools should enforce. Third, as a priority problem to provide better recreation activity, the policy for providing spare time, and the policy for developing leisure program should promote.

This paper deals with an efficient algorithm for generating the complete test set of every fault in combinational logic circuit, and fault detection and diagnosis technique based on Boolean Difference and Partial Boolean Difference. This study is mainly concerned with nonredundant combinational logic circuits. The type of fault is either stuck-at-o or stuck-at-1, i.e. at the input of a gate or at the output of a gate. The combinational logic circuits show a fault when the describing conditions correspond with the combinational logic circuits, for detecting S-A-O, or S-A-1, the method of generating test patterns is proposed, and the detection of fault at the circuit is attempted.

옥봉 금광상은 단층파쇄대를 충진한 함금열수맥상광상으로 구조운동에 수반되어 2회에 걸쳐 열수 광화작용이 진행되었다. 일렉트럼-방연석-섬아연석의 광화정출 작용은, 최대압력 50 기압하에서, 8.0-2.8wt. %. NaCl상당 염농도를 갖는 광화유체로부터 341-189℃에 걸쳐서 비등작용과 함께 냉각작용에 의하여 진행되었다. Electrum-galena-sphalerite mineralization of Okbong Au-mine was deposited in three stages of quartz vein and replacement which fill fault breccia zones, Fluid inclusion data shows that ore mineralization was deposits at temperatures between 341°and 189℃ from fluids with salinity between 8.0 and 2.8 equivalent weight percent NaCl. Sphalerite of Au-sulfide stage yielded homogenization temperatures between 221°and 214℃. Evidence of boiling indicates pressures of <50bars, corresponding to depths of 220 to 550 m, respectively, assuming lithostatic and hydrostatic loads. Au deposition was likely a result of boiling coupled with cooling.

嫌氣性 固定層 反應器에서 有機性 廢水와 COD濃度變化와 反應機내의 溫度變化에 따른 biogas生成에 관한 硏究
姜東秀,周昌植,黃德基,金裁禹 釜山工業大學校 1993 論文集 Vol.35 No.-
The effect of temperaure and influent COD concentration on the anaerobic digestion was studied in order to use the gas produced as an energy source. An anaerobic filter reactor was well applied to the continuous rise of temperature from the meso-philic(36˚C) range to the thermophilic(53˚C)range. The biogas production and methane contents on the mesophilic and thermophilic anaerobic treatment were compared. In addition, filter reactor was well applied to the continuous rise of influent COD concentration on 5,000mg/ℓ, 8,000mg/ℓ, 10,000mg/ℓ, 14,000mg/ℓdrawn, as follows ; Biogas production at 14,000mg/ℓyields higher than at 5,000mg/ℓ, but methane contents at 5,000mg/ℓwere the same as that at 14,000mg/ℓ. Biogas production at 53˚C yields higher than that at 36˚C, but methane contents at 53˚C were the same as that at 36˚C. The biogas production and methane contents at transition temperature(43˚C) yields lower than those at 36˚C and 53˚C.
