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

'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Ho dealt with the same themes that was found in 'The methodologies of Chinese history' but discussed it in terms of historical documents or events in Korea.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.

평형 및 불평형 공극의 조합에 의한 단상 BLDC 전동기의 코깅 토오크 저감

박성호,박승찬 동양대학교 산업기술연구소 2000 東洋大學校 産業技術硏究所 論文集 Vol.2 No.1

Most single-phase brushless DC(BLDC) motors have unequal air gaps to eliminate the dead-point, where the developed torque value is zero. However the unequal air gap length deteriorates the motor characteristics in cogging torque. Thus in this paper a new topology of unequal air gap is proposed to solve this problem. The topology is to combine equal and unequal air gaps. As a result, it is proved by the finite element analysis and experimental results that the proposed air gap topology is very effective in reducing the cogging torque of the single phase BLDC motor.

동학농민전쟁기 일본군ㆍ조선군의 동학도(東學徒) 학살

박찬승 한국역사연구회 2004 역사와 현실 Vol.- No.54

The 1894 genocide of Donghak believers during the period of the Donghak peasants' war can be summarized as follows. First of all, the Japanese army, the Joseon Gyeonggun (the army for the capital city), the local army, Yuhoegun (the Confucius army), and Mingun (the militia) committed the genocide. The executions were mainly done by Joseon Gyeonggun and the local army. Most of the decisions for execution were made by the Japanese army, who had command at that time. Yuhoegun and Mingun of Yangban (the upper class) often captured and handed over suspects to Gyeonggun and the local army. It was highly plausible that the following genocide guideline was made before October 16 when the Japanese reported to the Joseon government that they would send the Japanese army to suppress the Donghakgun (the Donghak army). The genocide guideline said that the Japanese would "put an end to Donghakgun." The Joseon government proposed that innocent people should be excluded, but the Japanese set the internal guideline for "extirpation" and "extermination" and gave the direct order to the 19th Battalion of Japanese Reserve Infantry which was sent. However, the massacre was not committed against every Donghak believer. Before the Jangheung Battle, the Japanese army and the Gyeonggun slaughtered the Donghak Believers who fought in the battle, who caused disturbances and created havoc, or who had appointment documents for leaders of Donghak among the arrested Donghak believers. After the Jangheung Battle, every Donghak follower found in Gangjin, Haenam, Jindo, etc. in the vicinity of Jangheung was executed. At this time, severe suppression occurred in Mujang, Heungdeok, Gochang, Yeonggwang, Hampyeong, Muan, etc. along the West coast where the Donghak influence was strong. It is assumed that thousands of Donghak followers were arrested and executed. The main force of the massacre was the 19th Battalion in Japanese army, which was specially reinforced to liquidate Donghakgun. The 19th Battalion, divided into three companies, drove Donghakgun in the Southwestern corner of Korea and chose to eradicate Donghakgun finally in Jangheung, Gangjin, Haenam, etc. in the Southwest. Lee Gyutae, Lee Duhwang, Lee Jinho, and Seong Hayeong of the Joseon Gyeonggun actively participated in the military operation.

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.

The purpose of this study is to search the affective contents of physical education presented in the seventh education curriculum, and to provide concrete data for improving the problems in the affective domain assessment by analyzing the reality of that assessment through surveying the teachers' thoughts and assessment criterion schemes. To reach the goal of this study, I searched affective contents presented in the seventh education curriculum after dividing it into two parts, contents and assessment. And I collected fifty-five performance assessment criterion schemes from as many schools in four cities in Kyeonggi Province, and analyzed them after classifying them into ten domains by their contents. The results are as followings ; First, in the seventh education curriculum on middle school physical education, the characteristics of the subject are prescribed and qualitative improvement of this subject is emphasized through teaching and assessing the sociality and development of sentiments, such as cooperative spirit, patience, satisfaction, sincerity and responsibility which are directly related to the physical education classes. Second, the main method of affective domain assessment was the demerit system, and the contents of assessment was about the students' uniform conditions . Many school assessed just preparing condition without assessing attitude. Concrete criterion and frequency for assessment were hardly showed in the assessment criterion schemes, so the tools for affective domain assessment was poor relatively when compared with psychomotor domain assessment. Third, the teachers recognized that affective domain in physical education was important, but they thought other teachers were concerned little about that domain. Assessment was doing not for understanding achievement degree of the class goal and improving teaching-learning method but for causing learning motive. Fourth, the mainly applied contents in affective domain assessment was the students' uniform conditions. And demerit system was widely used because it was easy but many teachers pointed out that this system had some problems from the viewpoint of the educational effect and fairness. As we've seen, the tools for assessment in schools were so poor that they were different from the contents of affective domain which was showed in the seventh education curriculum. And there were inconsistency and differences between the teachers' recognition and reality of affective domain assessment, so teachers' effort and concern are necessary.

The observer which is based on sliding mode is robust to uncertainties. It has the error dynamic independent on disturbances or noises. But its dynamics are very coservative because of its dependence of output error. So, in this paper, an observer with a novel sliding mode is proposed. The sliding mode of this observer is designed by defining a extended error state whose dynamic is determined from the output error. In addition to this advantage, the RLS algorithm is made more useful by proposing the data obtaining method from the existing experimental data. The performace of the sliding mode observer can be improved using the parameters from the RLS algorithm.

This paper Backstepping design with Sliding Mode Control for AC Servo Systems. The robustness of sliding mode control can be used for backstepping technique to solve the uncertainty problem. A scalar design using Lyapunov function is developed for high-order systems. The result can be easily extended to non-linear system and used with many other sliding mode control results.

ADP에 의해서 활성화된 혈관평활근 세포의 증식에 관여하는 Integrin의 종류와 신호 전달 경로

박찬복,이지현,류종철,차태준,주승재,이재우 고신대학교 의학부 2004 高神大學校 醫學部 論文集 Vol.19 No.1

Background: Adenosine diphosphate(ADP), which is usually secreted from activated platelets activates integrin αvβ3. αvβ5, and α5β1 on human vascular smooth muscle cells. Integrins have an important role in the proliferation of vascular smooth muscle cells. ADP may stimulate the proliferation of vascular smooth muscle dells by the activation of integrins. Integrins mediating ADP-stimulate the proliferation of vascular smooth muscle cells and signal transduction pathway of ADP stimulation were investigated in this study. Methods: MTT(3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) assay was used to evaluate ADP or ATP-stimulated proliferation of human aortic smooth muscle cells (HASMC). In some experiments, HASMC were incubated with U73122, an inhibitor of phospholipase C, or monoclonal antibodies (mAb) to integrins after ADP of ATP stimulation. Results: ADP and ATP increased the proliferation of HASMC in a dose-dependent manner. U73122 inhibited ADP or ATP stimulated proliferation of HASMC ADP-stimulated proliferation of HASMC was inhibited either by c7E3, a blocking mAb to integrin β3 or by LM609, a blocking mAb to integrin αvβ3(37% and 26% inhibition, respectively: p<0.05), but neither by P1F5, a blocking mAb to integrin αvβ5 nor by JBSS, a blocking mAb to integrin α5β1. Conclusion: These results indicate that ADP increases the proliferation of human vascular smooth muscle cells through phospholipase C pathway, and only integrin αvβ3 mediates ADP-stimulated proliferation of human vascular smooth muscle cells.
