본 연구에서는 Nayfeh등과 이원경과 소강영은 조화가진하의 핀과 꺽쇠로 고정 된 보(hinged-clamped beam)의 강제 진동 해석을 통하여 점근적으로 안정한 정상상태 응답이 둘 이상 존재할 수 있음을 알게 되었다. 본 연구에서는 이 경우에 접근적으 로 안정한두 정상상태 응답을 구하고 이들 안정한 해로 각각 흡인되는 초기조건들의 집합인 흡인영역을 보간사상법(interpolated mapping method)과 직접 수치적분에 의해 구한 후 서로 비교하였다. A nonlinear dissipative dynamical system can often have multiple attractors. In this case, it is important to study the global behavior of the system by determining the global domain of attraction of each attractor. In this paper we study the global behavior of a forced beam with two mode interaction. The governing equation of motion is reduced to two second-order nonlinear nonautonomous ordinary differential equations. When .omega. /=3.omega.$_{1}$ and .ohm.=.omega $_{1}$, the system can have two asymptotically stable steady-state periodic solutions, where .omega./ sub 1/, .omega.$_{2}$ and .ohm. denote natural frequencies of the first and second modes and the excitation frequency, respectively. Both solutions have the same period as the excitation period. Therefore each of them shows up as a period-1 solution in Poincare map. We show how interpolated mapping method can be used to determine the two four-dimensional domains of attraction of the two solutions in a very effective way. The results are compared with the ones obtained by direct numerical integration.

The aim of this study was to use narrative inquiry to explore the experiences of medical students who faced expulsion, military service, and readmission, and their journeys of identity formation. Three medical students were recruited via snowball sampling, and each participant was interviewed twice. According to the sequence of experiences, their stories were summarized as follows: the process of being expelled, the military service experience and readmission process, and the present. Before all three students were expelled, they lived dissolute lives free of concern from the entrance examination and failed to cope well with dropping out. They felt that military experience had helped them develop interpersonal skills in the clinical setting and the strength to withstand a difficult crisis. Two students were motivated to become doctors after military service, but the other was not. They had reflected deeply over their unique experiences. The scars imprinted from their experiences became a means of stimulation, and they ultimately acquired the resilience and ability to accommodate for and counteract their weaknesses. This appears to have been an important influence on their identity formation. The narrations of their rare experiences can help medical educators more fully understand and support medical students through difficulties, specifically with regard to academic failure or expulsion. These findings may prompt medical professors to think about the kind of guidance or motivation that could help students before expulsion, rather than assuming that they are simply lacking academic ability.

중국 노동환경 변화와 외자기업의 노무관리 연구: 신노동자의 노동문화 형성과 대응전략

이원경 중국지역학회 2022 중국지역연구 Vol.9 No.4

Since China's labor problem is extensive issues covering the entire ruling power, labor should be discussed under the socialist market economy, it suggests the necessity of changing the labor management strategy of foreign-invested companies according to changes in the labor environment. New workers arose from a new generation of peasant workers who were alienated despite being the main player of economic growth. They are classified, organised and actively seeking rights, and the labor culture they formed is a factor that induces changes in the social system. The management strategy to improve the performance of foreign-invested companies results in the localization, and establishing labor management localization strategy in response to the labor culture of new workers enable them to overcome the limitations of foreign-invested companies and eventually it will be a strategy to integrate into society as a local settlement company. 본 연구는 중국의 노동문제는 통치 전력 전반을 포괄하는 광범위한 문제이므로 사회주의 시장경제체제 환경 하에서 노동을 논해야 하며, 노동환경 변화에 따른 외자기업의 노무관리 전략 변화의 필요성을 시사하고 있다. 경제성장의 주역이면서도 소외되었던 신세대 농민공에서 태동한 신노동자는 계급화, 조직화되며 적극적인 권리쟁취 행동에 나서고 있으며 이들이 형성한 노동문화는 사회체제의 변화를 추인하는 요소이다. 외자기업의 경영성과 제고를 위한 경영전략은 현지화로 귀결되는데 신노동자의 노동문화에 대응한 노무관리 현지화 전략의 수립은 외자기업의 한계를 극복하고 궁극적으로 현지 정착기업으로 사회에 융화되는 전략이 될 것이다.

VAXIMA를 이용한 비선형 보존 동역학계의 해석

이원경 대한기계학회 1990 대한기계학회논문집 Vol.14 No.3

본 연구에서는 Lindstedt-Poincare 방법을 이용하여, Duffing 진동계에 5차항 을 포함시킴으로써 진폭이 더 큰 운동에도 타당성이 있는 근사해를 구하고자 한다. VAXIMA를 사용하여 해석하는 과정은 부록에 첨부되어 있으며 이 작업은 VAX 11/750 컴 퓨터에서 수행된 것이다. VAXIMA is a computer software which gives us results in terms of parameters. We use VAXIMA to analyze quantitatively a conservative dynamical system with cubic and quintic nonlinear terms. The system is described by a nonlinear second-order autonomous ordinary differential equation. Using the Lindstedt-Poincare method, we obtain period-amplitude characteristics. In order to check the validity of the approximate solution, we integrate numerically the equation of motion.

First of all, consulting with client is the most important in any treatment concerning with hair or scalp to be able to analyse accurately. In addition to the consulting, the hair designer should be able to give a correct treatment having accurate analysis about client's present condition with the aid of hair or scalp scopes. Second of all, as scalp or hair care is a comptetely different system from what is done in general beauty shop such as hair styling, it should be only managed by a specialist who has knowledge about the hair and scalp and only with that way this new system would be reliable and specialized. I found that the hair could be protected from various external damaging factors with the professional and systematic reatments. Particularly with the recent trends of hair coloring being wide spread, it is the right time for these new concept of, hair care, should be dealt by cosmetelogist concerning with hair. Lastly, the basic concept in scalp or hair care is what is literally means $quot;care$quot;. Therefore we are only allowed to treat scalp or hair with only minor conditions and to give continuous consulting and treatments in order to keep healthy and strong. In other words hair and scalp care centers are not belong to clinic and we should advise and client with serious conditions or required special treatment to consult with physician without hesitation.

국내 모발관리 샵 운영의 방향제시를 위한 연구 : 선진 모발관리 샵의 경영실태조사에 따른 according to the survey of the managing condition of the advanced hair shops

이원경 한국미용학회 1998 한국미용학회지 Vol.4 No.1

We could not discuss any work of hair style excluding hair material. Recently, people are increasingly recogniging the necessity of a special management of hair. As the damage and loss of one's hair are deepening by the environmental pollution caused modernization, the more frequent stimulus of coloring perm and styling cosmetics, and his or her ill health and stress, one's desire for the hair management has been increased. So in this thesis, we will examine the hair care of French people who has accumulated know-howl of hair care for a long time, and the special hair shops in Japan whose active work and research is well-known, and then, we will compare. And we will study their management of hair shops and their hair course, and then suggest the model of an advanced hair shop in our country. Their interest in hair care begins when the hair gets dry by the shortage of fat or water inside hair. In other words, they treat hair as they do skin. For the continuing management of hair, people should care for their hair with special cosmetics complying to the style recomended by a special hair shop. Therefore, esperts recommend this care method to the hair-treated, and the hair-treated care their hair at home with the same cosmetics which the shops use. We can think this is an ideal hair technique, in which the carer, the cared, and special cosmetics make a trinity. In the past treatment, perm, cut, and coloring were done respectively, but nowadays, they are all related. Healthy hair improves the qualitative and touchy sense, and the line of hair. Therefore, through the continuous care, we could stop the damage of hair by the repetitive treatment and various factors

The population living in the former Eastern Bloc and the former Soviet Union areas with a sense of identity as Germans is estimated to be about 1.5 million now. At the heart of the identity as Germans should be German, their heritage language. In this paper, the linguistic policies of Germany for the preservation of the heritage language are surveyed centering on the following matters. First, several practical issues that appear when international conventions for linguistic minorities are applied locally are discussed. Second, the present situation of the German minorities in these areas is surveyed with a focus on the historical background. Third, the characteristics of German minority language policies are assessed through the cases of implementation of specific programs that implement the language policies in these areas. Finally, several implications on language policies for Korean as a heritage language are discussed. 이 연구는 중부유럽의 동ㆍ남동부 및 동부유럽, 구소련지역에서의 계승어로서의 독일어에 대한 논의이다. 오늘날 이 지역에 독일인이라는 자의식을 갖고 사는 인구는 150만 명가량으로 추정되는데, 그 정체성의 핵심에는 이들의 계승어인 독일어가 있다. 이 연구에서는 다음과 같은 사항을 중심으로 계승어로서의 독일어에 관한 독일 언어정책의 특성을 조명함으로써 현대사회에서 계승어 보전이 갖는 의미를 고찰하고 있다. 첫째, 언어적 소수민을 대상으로 하는 언어정책들의 근간이 되는 국제적 협약들이 현지에서 적용될 때 나타나는 몇 가지 현실적인 문제점들을 조명한다. 둘째, 해당 지역 독일소수민의 현황을 역사적 배경을 중심으로 개관하고 지역 간 공통점과 지역별 특수성을 논의한다. 셋째, 이 지역에서 주무부서 및 지원부서의 언어정책을 실현하는 구체적인 프로그램들의 시행사례를 통해 독일소수민 언어정책의 특성을 평가하고, 끝으로 계승어로서의 한국어 언어정책에 주는 시사점 몇 가지를 논의한다.

영어 여격 구문의 논항구조와 의미역 연구

This study attempts to explore the argument structure of dative verbs in English and examines the properties of semantic roles. The theoretical framework for a syntactic analysis is mainly from Chomsky's(1981) generative grammar, represented by Government and Binding theory, while the one for a semantic analysis is based on the argument structure coupled with thematic roles proposed by Fillmore, Givon and Grimshaw. The dative constructions in English have two forms : X-V-NP_1-P-NP_2 and X-V-NP_2-NP_1. When the two NPs following by a dative verb alternate with each other, the preposition is deleted and the word order of them is changed. Two possible theories of this dative alternation are considered: one is that two forms are base-generated, and the other is that one of these structures is base-generated and the other is derived by transformations. The result of the alternation makes two different natures of the construction: one is unmarked and the other is marked, a construction changing stylistic properties, such as politeness, focus and emphasis. There is systematic relationship among the agent, the recipient/benefactive and the theme associated with the argument structures of predication on dative constructions. The semantic features of argument structures are discussed. The agent has the feature[±volition][±human]. When the theme has the feature [+alienable], it is free to change the theme and recipient/benefactive. The recipient and the benefactive have the feature [+animate]. Semantic features of prepositions preceding the recipient or the benefactive are presented.
