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Ho dealt with the same themes that was found in 'The methodologies of Chinese history' but discussed it in terms of historical documents or events in Korea.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

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.

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.

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.

In this study, we have developed the simulation tool in order to investigate driving trajectory of AGV for container transport. AGV for container transport is different from the indoor AGV in that it is a large size structure at being loaded the weight of 40 ton. And AGV for container transport is applied to front wheel steering, rear wheel steering, all wheel steering, and crap steering. Therefore, we have developed the simulation tool considering dynamic problems and a center of turning in accordance with fourth ways of steering mode. As the result of this study, we have confirmed that this tool is useful and cost-effective in the dynamic analysis or large size vehicles. Also, it is useful to calculate the minimum radius of turning for large size vehicles.

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.
