  • The nonstationary vibration of a rotor carrying two discs with a limited driving torque is studied theoretically by using the method of the perturbation theory. The influence of the asymmetry, torque, damping and phase difference in passing through a critical speed is studied in detail, considering the interaction between the driving source and the vibration system.

  • 본 연구에서는 수평하중을 받는 깊은 기초에서 나타나는 지반과 기초의 상호작용을 분석할 목적으로 전통적인 소성이론을 응용하여 개발한 단자유도의 매크로요소 모델을 제시하였다. 제시한 매크로요소 모델은 지반에 매립된 깊은 기초가 수평하중을 받을 때 지반과 기초사이에 발생하는 응력의 제 성분을 각각 모델링하고 합성함으로써 구성하였는데, 이는 기초와 지반의 상호작용을 단순 스프링으로 모델링하는 기존의 방법에 비해 상호작용에 관련한 응력을 성분별로 분리하여 제공하는 장점이 있다. 본 연구에서는 상호작용과 관련한 응력의 제 요소를 마찰력과 측압저항으로 크게 분류하고 각 요소를 소성이론을 이용하여 모델링하였으며, 최종적으로 이들을 병렬로 조합하는 방식으로 매크로요소를 구성하였다. 제시한 매크로요소를 이용하여 점성토에 매립한 깊은 기초가 수평하중을 받는 경우를 해석한 결과 기초의 전체적인 거동과 더불어 상호작용 매크로요소를 구성하는 각 요소들로부터 상호작용 음력의 제 요소들을 분석해 냄으로써 기존 모델에 비해 개선된 결과를 얻을 수 있었다.

  • This research is about the methods in making computers understand the situation in regards to interaction between House and Human Behavior. In this paper, house is the ubiquitous house, as a future house, adopting ubiquitous computing presenting the interrelation of human and house - interior space, architecture, nature. And the Context Aware Model of ubiquitous house is proposed to embody the ubiquitous house. The research objective is to systematize the context in the ubiquitous house and suggest a theoretical basis to embody the ubiquitous house interacting between the House ud Human Behavior Especially, this paper focuses on the Context Aware Model based on FengShui-Theory(sp. YangTaek-Theory). The ubiquitous house is not what operates passively by human but a information-oriented house that can predict the situation and the living patterns of human. For a information-oriented house and informal living context at home, this paper uses FengShui-Theory whose central concern is the interrelation of human and nature. Through these concepts, this research will suggest how to systematize, control and manage the context at home. In the end, it is expected to offer a theoretical basis to embody the intelligent house and apply an environment design communicating between the computers and human.

  • Over the years, several different approaches have been proposed to enhance the practice of software reuse. These approaches vary in reuse abstraction levels or application domains they focus on. However, it seems that they do not adequately meet the needs of software designers in planning and managing reuse. One reason may be the lack of conceptually well-established framework supporting work domain analysis and modeling. As a new viable solution to this problem, Sutcliffe and his colleagues developed Domain Theory , which is introduced in this paper. Utilizing multidisciplinary perspective, such as cognitive psychology, management science, human-computer interaction, and software engineering. it provides a schematic framework that defines a comprehensive library of generic and reusable models of domain knowledge in terms of generic tasks and meta-domains. It also provides useful methods and guidelines for software reuse, emphasizing the concept of abstraction process in a designer s mind. This paper firstly gives a brief overview of fundamentals of software reuse. Next, it explains the foundation of domain theory and discusses its applicability to software reuse. In particular, the taxonomy of meta-domains and the types of generic tasks are described in more detail. Finally, the future research framework, which primarily addresses the problem of how to apply the domain theory to various work domains, is proposed.

  • This study is the analysis of characteristics of hospital space for the holistic healing environment of children on the basis of the healing theory on emotion of Max L$\ddot{u}$scher and the healing theory on senses of Rudolf Steiner of the overseas children's hospitals. According to the theory of Rudolf Steiner, children make comprehensive advancement of physical, spirit and soul through the interaction of 12 senses. In addition, Max Luscher asserts that the psychological health can be maintained when the 4 emotional status in content, confidence, self-esteem and liberty make the balance. The 4 elements of Luscher have correspond with spatial expression elements for refuge, flow, prospect and void, and this is analyzed in conjunction with the eight kinds of behavior affordance of ying and yang (-, +) that helps our the advancement of 12 senses of Steiner. WORK & STUDY(+), REST(-), MOBILITY(+), VISUAL SEQUENCE(-), SOCIAL EXCHANGE(+), REFRESHMENT(-), COMMUNITY(+) and MEDITATION (-) would be the 8 kinds of behavioral affordances to make the healing environment as presented in this study and the case analysis for children's hospitals have been undertaken.

  • This study, guided by Engeström's (1999, 2001) activity theory which owes its theoretical lineage to sociocultural theory, explores how roles (peer feedback givers and receivers) and tasks are distributed among EFL students who engage in peer response. More specifically, as an extension of previous research of focusing on "stances" ESL students adopt, I investigate whether different roles in peer response groups make a difference in the nature of peer response and identify what underlays the different roles in peer group interaction. In addition, I examine whether different roles to the peer response create tensions and contradictions in peer response and how these created conflicts lead to changes in peer response activity system. The data I wish to consider is first-person narratives elicited from two EFL college students. I use Won's and Choi's (both pseudonyms) stories as a heuristic, which is a method that allowing one to proceed fruitfully in finding information. Foregrounded in this study are the students' different roles in the same peer response activity. A division of labor exists between Won/Choi and their peers - the way tasks are divided up and the way roles are structured. Yet Won and Choi adopted rather divergent roles when participating in peer response activity and carried out qualitatively different peer response activities. It is obvious here that the distribution of their roles in carrying out this particular peer response is shaped by Won' and Choi's perception about the validity of their peers' responses.

  • Acetaminophen (AAP) and ranitidine (RT) were coadministered orally to nine rats, and the possible contribution of the gastric emptying to the plasma concentration profiles of them was examined. The drugs showed multiple plasma peaks similar to the respective ones after separated administration of each durg. IT Implies that there is no significant interaction between AAP and RT in terms of the gastric emptying or drug absorption. There were no significant linear correlations of the peak patterns (peak height and peak time) between AAP andd RT. It is contrary to the expectation from the biphasic gastric emptying (BGE) theory previously suggested for AAP and RT. The BGE theory. Therefore, seemed to have some draw-backs in explaining satisfactorily the multiple plasma peaks of AAP and RT. Two more doubts raised previously against the BGE theory were also discussed.

  • The energetics of defects in the presence of domain walls in $LiNbO_3$ are characterized using density-functional theory calculations. Domain walls show stronger interactions with antisite defects than with interstitial defects or vacancies. As a result, antisite defects act as a strong pinning center for the domain wall in $LiNbO_3$. Analysis of migration behavior of the antisite defects across the domain wall shows that the migration barrier of the antisite defects is significantly high, such that the migration of antisite defects across the domain wall is energetically not preferable. However, further study on excess electrons shows that the migration barrier of antisite defects can be lowered by changing the charge states of the antisite defects. So, excess electrons can enhance the migration of antisite defects and thus facilitate domain wall movement by weakening the pinning effect.

  • This paper explores the influences of the traditional Chinese culture on social relations in China. It provides an introduction to the concept of Guanxi, the notion that social connections are based on socially situated reciprocity. This is different from social interaction in Western society that is based on self-interest and equity. Guanxi represents the foundation of social networks in many Eastern countries. As such, the study of social networks in China requires scholars to examine Guanxi networks. The paper demonstrates how a Guanxi perspective might be added to the examination of various theories that comprise structural (network) theory, including social capital theory, social exchange theory, cognitive and contagion theories, and the role of homophily for the study of Chinese society and its social organizations.
