박재현,김승철,한창훈,박종오,임영도 東亞大學校 附設 情報通信硏究所 1998 情報通信硏究所論文誌 Vol.6 No.1

In a case of driving beginnners, it is very difficult to park a car perfectly because driver's knowledge makes more errors than intelligent mechanism when they are performed repeatedly. However skilled drivers be of experienced knowledge are able to park a car quickly. In this paper, we analyzed driving patterns of skilled drivers, designed the fuzzy controller to park based on it, and perform auto-parking simulation of a car using that controller.

1920년대 申采浩와 梁啓超의 역사연구방법론 비교 : E. 베른하임을 참고하여

박찬승(Park, Chan-Seung) 한국사학사학회 2004 韓國史學史學報 Vol.0 No.9

'Introduction' of the book 'Korean ancient history' written by Shin Chae Ho was highly influenced by Liang Qichao's(1873~1929) book 'The methodologies of Chinese history'. Shin Chae Ho borrowed many ideas and most of the organizational framework of his 'Introduction' from Liang Qichao. Shin Chae Ho dealt with the same themes that was found in 'The methodologies of Chinese history' but discussed it in terms of historical documents or events in Korea. Since Liang Qichao referred to 'Introduction to history' written by Ernst Bernheim when he wrote his book, it can be assumed that modern methodologies of western history was adopted by Shin Chae Ho in his 'Introduction'. Shin Chae Ho believed that history is a document of mental activities that develop both spatially and temporally. He emphasized the importance of objective descriptions of historical facts. He also knew the importance of explanations for causal relationship in writing history and of studies of historical records. All these reflect the influences of Liang Qichao and Ernst Bernheim on Shin Chae Ho. However, Shin Chae Ho had his uniqueperspectives as well. For example, he said that history is a struggle between 'me'(or 'us') and 'others'. He also emphasized the importance of specificities and uniqueness of each nation(Minjok). These are indications of his own 'nationalistic history'. In summary, Shin Chae Ho adopted modern methodologies in Western history from Liang Qichao and Ernst Bernheim and developed a new methodology of his own. We now call it methodology of nationalistic history.

Correlation of hydrolysis rate, total solid content and Volatile fatty acid yield in anaerobic digestion of papermil1 sludge using Rumen microorganisms and conventional acidlogenesis were summarized as follows ; 1. Ultimate volatile fatty acid yield and hydrolysis rate produced by rumen microorganisms and conventional acidogenesis were about 7.2megVFA/gVS. 0.175-1 and 6.8meqVFA/gVS, 0.103d-1. Therefore, hydrolysis rate by rumen microorganisms was 1.7times faster than that of conventional acidogenesis. 2. During the operating, VFA composition ratios(%) produced by rumen microorganisms were acetate:propionate:butyrate=64=5: 27±7: 9±2. At 5,10,13 and 6.83meqVFAg/VS, respectively. 3. When effluents produced by MAR and RMR were anaerobically digested, methane yields were 0.27 and 0.29 ℓ CH₄/gCOD_(rem) respectively.

박승찬 龍仁大學校 2004 용인대학교 논문집 Vol.22 No.-

The purpose of this paper is to describe the recent trends toward Chinese technology-intensive industries, changes in Chinese technology policies, trade patterns for the better understanding of Korean firms entering into Chinese markets, Indeed, Chinese economy has highly developed over 10% annual growth rate as the results of reforming and opening polices since 1979. Also, Chinese technology markets have rapidly changed due to the concerned policies on technology transfer and technology transformation after Chinese entrance into WTO on November, 2002. Furthermore, the paper summarizes the most recent Chinese major technology policies such as Key Technical Problem Tacking Program, Spark Program, S&T Achievement Promotion Program, Hight-tech Research & Development Program, Torch Program, Basic Research Program, and so forth. Finally, the paper attempts to analyze Chinese venture firms' structures, and furnishes Korean venture firms with several alternatives to enter into Chinese markets.

海松伐採木에서 솔껍질깍지벌레의 時期別 斃死率

朴承瓚,朴南昌 全南大學校 農漁村開發硏究所 1990 農業科學技術硏究 Vol.25 No.-

솔껍질깍지벌레 若蟲이 서식하고 있는 海松被害木을 시기별로 伐採하여 成蟲羽化期까지 시기별로 약충의 斃死率을 조사한 바 10월 벌채목에서는 익년 2월까지 모든 개체가 폐사하였으나 12월 벌채목에서는 익년 3월, 즉 성충우화가 시작되는 시기까지 다수가 생존하고 있었다. 본 해충의 年中 蟲態變化와 관련하여 벌채목운반에 의한 인위적인 피해확산을 방지하기 위한 벌채시기는 7월내지 9월로 판단된다. Japanese black pine(Pinus thunbergiana) trees infested by nymphs of the black pine bast scale (Matsucoccus thunbergianae) were cut, and survival of the nymphs on cut trees was examined periodically until emergence time of the scale in infestation area. All the nymphs on the trees cut in October died by the next February, but many of those on the trees cut in December survived until the next March, when adults begin to emerge in the field. In order to avoid the expansion of infestation by the transportation of cut logs infested by the scale, trees should be cut between July and September, but those cut trees may be moved out of the infested area at anytime of the year.

Slaughterhouse wastewater containing high ammonium ion concentration and organic matter was treated by upflow anaerobic sludge blanket(UASB) reactor. As organic loading rate(OLR) was increased from 0.25㎏COD/㎥·day to 8.0㎏COD/㎥·day, COD removal efficiency was about 80 percent. But in case of OLR increased up to 8.0 ㎏COD/㎥·day, organic removal efficiency was decreased. In case of OLR was increased from 0.25㎏COD/㎥·day to 8.0㎏COD/ ㎥·day and ammonium loading rate was increased from 0.02 ㎏ NH₄^(+)-N/㎥·day to 0.62 ㎏ NH₄^(+)-N/㎥·day, effluent ammonium ion concentration was decreased from 1800㎎/l to 720㎎/l. Biogas production was increased form 0.248 ㎥/㎏COD_(rem) to 0.280 ㎥/㎏COD_(rem) in case of OLR was increased from 0.25 ㎏COD/㎥·day to 6.0 ㎏COD/㎥·day. Methane, carbon dioxide and ammonia gas content were 49%, 49% and 2.0% respectively in initial OLR was 0.25 ㎏COD/㎥·day but ammonia gas does not produced in case of OLR was increased up to 4.0 ㎏COD/㎥·day. In proportion to decrease hydraulic retention time, MLSS concentration in upflow anaerobic sludge blanket reactor was increased.

부신피질 자극호르몬 단독결핍은 국내에서 7례만이 보고된 희귀 질환이며 병인 및 경과 등 아직 불분명한 측면이 많다. 이는 질환지체의 희귀성도 있지만 치료후 자연경과에 대한 장기적인 추적검사가 이루어진 경우가 드물기 때문이기도 하다. 저자들은 비특이적인 전신증상을 주소로 내원한 폐경기후의 56세 여자 환자에서 자가면역질환의 증거없이 고프로릭틴혈증을 보인 부신피질 자극호르몬 단독결핍 1례를 경험하고 1년간의 부신피질호르몬 대치요법후 추적검사를 실시하였기에 문헌 고찰과 함께 보고하는 바이다. Isolated ACTH deficiency is a rare disorder which shows secondary adrenal insufficiency with normal states of other pituitary hormones. A 56-year-old postmenopausal woman complaining general weakness and intermittent mental confusion presented negligible serum cortisol and ACTH level with hyperprolactinemia and mild hyponatremia. Rapid ACTH stimulation test did not show significant increase of serum cortisol level. Combined pituitary stimulation test showed negligible response of cortisol and ACTH, and slightly decreased response of prolactin and gonadotropin. But the responses of TSH and GH were normal. There was no evidence of organic pituitary of hypothalamic lesion in brain MRI and antithyroid autoantibody was not detected in serum. After receiving 12 months of glucocorticoid replacement therapy, she skipped the medicine for 3 weeks and we performed follow-up endocrinologic tests. Serum ACTH and cortisol level was also negligible and prolonged ACTH simulation test showed normal response of serum cortisol. CRF stimulation test showed no response of serum ACTH. Basal prolactin level was decreased to near normal and combined pituitary stimulation test showed normal response of prolactin with slightly blunted response of TSH and GH. We concluded that the case was nonautoimmune origined isolated ACTH deficiency which was accompanied by hyperprolactinemia and resultant deficiency of gonadotropin, so we report this case with review of literatures.

본 논문에서는 필기체 숫자인식의 최적 신경망 구조 설계를 위하여 유전자 알고리즘과 역전파 알고리즘을 병합하는 방법을 이용하였으며, 유전자 알고리즘은 유전인자의 역할에 따라 독립적으로 적응하는 개선된 선택, 교배, 돌연변이 연산자를 제안하였다. 실험결과는 유전인자의 역할에 적응하는 개선된 연산자들의 실행으로 최적의 신경망 구조를 설계하였고, 설계된 신경망 구조에서의 학습이 가장 좋은 성능을 나타내었다. In this study, the method of using both genetic algorithm and back propagation is proposed to design the structure of optimal neural network recognizing handwritten digits. Improved selection, crossover and mutation operator which can control the genetic algorithm independently according to the role of gene are used in the proposed method. Simulation result shows that the neural network of this method can search effectively the optimal hidden node numbers, connection weight, learning rate and the momentum because of above proposed operators.
