This paper presents the motion control of a mobile robot with arc sensor for lattice type welding. Its dynamic equation and motion control method for welding speed and seam tracking are described. The motion control is realized in the view of keeping constant welding speed and precise target line even though the robot is driven along a straight line or comer. The mobile robot is modeled based on Lagrange equation under nonholonomic constraints and the model is represented in state space form. The motion control of the mobile robot is separated into three driving motions of straight locomotion, turning locomotion and torch slider controls. For the torch slider control, the proportional integral derivative (PID) control method is used. For the straight locomotion, a concept of decoupling method between input and output is adopted and for the turning locomotion, the turning speed is controlled according to the angular velocity value at each point of the comer with range of $90^{\circ}$ constrained to the welding speed. The proposed control methods are proved through simulation results and the results have proved that the mobile robot has enough ability to apply the lattice type welding line.

With the development of market economy, it has been a legislative trend to establish a system for vicarious liability of employers. China also established Tort Liability Law of People's Republic of China in 2009 and ruled responsibility of the employers for the acts for their employees through Art. 35. First, the employer's right to indemnity to an employee should be recognized, because employer's superintendence is much weak and economic power is similar between them. Second, an employer should take a responsibility for an unpaid employee as vicarious liability, because the Law did not exclude them from employees. Lastly, in case the Law conflicts with Interpretation of the Supreme People's Court on Certain Issues Concerning the Application of Law in Trying Cases Involving Compensation for Personal Damage, the Law should be regarded it has priority based on several related Principles. Regarding these matters, this study guides you to an analysis of vicarious liability of employers in China, benefits with a view to the perfection of the vicarious liability regime.

After we looked back on the process western psychotherapy, and consider current meaning and necessity of buddhism. we concluded as follows 1. We can apply buddhism to psychotherapy in terms of oriental medicine. Especially buddhism with long history in the orient has similarity with oriental medicine and common cultural background. therefore it will be useful especially to koreans 2. Whereas buddhism's object is Nirvana, that of medicine is to return to the above view. to apply various methodologies of buddhism to psychology of oriental medicine you must select useful parts and drop others 3. Whereas buddhism centers on human mind, oriental medicine wholly describes body and mind without separation, buddhism put stress on inside of consciousness and oriental medicine put stress on revealing process 4. It is difficult to combine buddhism to oriental medicine theoretically. In combining it is easier to accept buddhism practically rather than theoretically 5. To apply buddhism clinically we have to modify buddhism to modern societies and to research and discussion to combine it to the system of oriental medicine

Purpose: The purpose of this study was to explore the experiences of Tai Chi in women with osteoarthritis. Methods: Data were collected by face-to-face interview from 14 participants. Theoretical sampling was performed until the concepts were saturated. The main question was "How do you describe your experience of Tai Chi?" Data were analyzed using a grounded theory methodology. All interviews were audio taped and transcribed verbatim. Results: The Phenomenon is 'QI flowing'. The core category was identified with 'inspiring one's life with strength'. This series of processes was categorized into four stages: 'Challenging Tai chi', 'Doing one's best', 'Deplenishing (the word used in English and Tai chi is emptying one's mind) one's mind', 'Taking a Positive view of life'. Conclusion: The finding of this study will offer profound understanding about the reported tai chi's experience. Additional research should be done as to the role of Tai chi as a nursing intervention strategy for osteoarthritis patients.

Food is important to any animal, and a large part of the behavioral repertoire is concerned with ensuring adequate nutrition. Two main nutritional sensations, hunger and satiety, produce opposite behaviors. Hungry animals seek food, increase exploratory behavior and continue feeding once they encounter food. Satiated animals decrease exploratory behavior, take rest, and stop feeding. The signals of hunger or satiety and their effects on physiology and behavior will depend not only on the animal's current nutritional status, but also on its experience and the environment in which the animal evolved. In our novel, nutritionally rich environment, improper control of appetite contributes to diseases from anorexia to the current epidemic of obesity. Despite extraordinary recent advances, genetic contribution to appetite control is still poorly understood partly due to lack of simple genetic model systems. In this review, we will discuss current understanding of molecular and cellular mechanisms by which animals regulate food intake depending on their nutritional status. Then, focusing on relatively less known muscarinic and cGMP signals, we will discuss how the molecular and behavioral aspects of hunger and satiety are conserved in a simple invertebrate model system, Caenorhabditis elegans so as for us to use it to understand the genetics of appetite control.

인식의 주체와 대상만을 고려하는 인식론은 그들을 둘러싸고 있는 사회의 역할에 대해 만족할 만한 설명을 주지 못한다. 이 논문에서는 인식의 주체를 가능하게 하는 언어적, 사회적 조건을 논의하는 구조주의와 기호학적 인식론의 철학적 기초를, 주체, 구조, 담론이라는 세 가지의 키워드를 중심으로 하여 분석한다. 기호의 의미란 인식의 대상으로부터 비롯되거나 주체가 스스로 구성하는 것이 아니라 기호들의 망 속에서 기호들 사이의 관계에 의한 의미작용으로부터 주어지는 것이다. 그 구조는 주체 이전에 존재하는 것이며, 오히려 그러한 구조적 질서 안으로 들어감으로써 주체는 형성된다. 수학 학습을 이해하고 분석하는 경우에도 이러한 관점은 주체에 의한 지식의 구성 이외의 다른 많은 논점들을 생각하게 하는 출발점이 된다.

The author analysed the routine radiographic changes and clinical symptoms of 205 cases of temporomandibular joint arthrosis. The clinical symptoms of the patients were classified and the morphological ylar head, articular eminence, and articular fossa were analized and discussed view point. The positional changes of condylar head and articular fossa relatation in TMJ arthrosis were observed. The frequencies of coincidence between the site of complaints and the site of the abnormal images which could be detected were examined. The results were obtained as follows; 1. Bone erosion, deformity, marginal proliferation and sclerosis were selected from many abnormal images as the radiographic diagnostic criteria of TMJ arthrotic lesions. 2. Abnormal radiographic findings were revealed in 150 cases (73.9%) of 205 total TMJ arthrosis cases and site with abnormal findings coincided with the site of complaints in 106 cases (70.7%) of 150 cases and coincidence rates were higher above fourth decades than below third decades. 3. Sclerosis of the abnormal radiographic findings could be found more often below third decades than above fourth decades. 4. The positional changes of condylar head were revealed in 176 cases (85.9%) of 205 total cases. 5. Pain complaints were revealed in 170 cases(82.9%) and clicking sounds were revealed in 120 cases (58.6%) of clinical symptoms of TMJ arthrosis. 6. No tendency was found so far the differential diagnosis between pain dysfunction syndrom and osteoarthrosis of TMJ.

Objectives : In this study, the meaning of Wuxing(五行) and Ganji(干支) in Suwenrushiyunqilunao (素問入式運氣論奧) and Wuxingdayi(五行大義) is reviewed to compare the interpretations of Wuxing and Ganzhi. Methods : The explanations of Wuxing, Sipgan(十干) and Sibiji(十二支) in the chapters of Suwenrushiyunqilunao and Wuxingdayi were studied to find different points of view. Results : Suwenrushiyunqilunao explained the meaning of Wuxing and Ganji using expression and metaphors of Yinyangwuxing(陰陽五行) theory while Suwenrushiyunqilunao describe their fragmentary characters. Also, Suwenrushiyunqilunao attached each one of Wuxing to substance(質), rule(理), shape(形), nature(性), righteousness(義). Conclusions : The differences of the explanations between the books point that there has been a deepening understanding of Yinyangwuxing and developments of Yunqixue(運氣學) in about 500 years from the publication of Wuxingdayi.

Electron microscopic studies were carried out to investigate the fine structure of ommatidia of the compound eyes in Meimuna mongolica D. The crystalline cone appears round, and is composed of four double-membraned cone cells and surrounded by pigment cells having many pigment granules. The rhabdom is a closed type, and is composed of four rhabdomeres Its cross section reveals lamellated microvilli which are oriented in four different directions suggesting that these represent four photoreceptive sites. The microvilli, in a cross sectional view, are hexagonal in shape with a central axis inside. There are usually eight retinular cells arranged radially from the rhabdom, but in some retinular layers seven or nine retinular cells could be observed. The cytoplasm of each retinular cell is interconnected with that of microvilli of the rhabdomere, but the appearance of this interconnection varies depending on the number of retinular cells.'The retinlilar cells neighboring the microvilli seem to have well-developed perirhabdomal vacuoles and mitochondria as well as pigment granules surrounding these vacuoles.
