The purpose of this study was to identify and understand the meaning and structure of librarians' experience of occupational socialization. Two in-depth interviews were conducted with each of the sixteen participants, practiced above 5 years in libraries and selected by theoretical sampling. Colaizzi's method of phenomenological interpretation was used to arrive at themes that represent what the experience of being a librarian meant to participants. Five thematic categories emerged from the data: 1) growing through deepening work and extending ability, 2) adapting the organization culture, 3) come to maturity along with users, 3) having double consciousness of the profession, 4) seeking self-realization as a librarian. Thus, librarians' experience means to orient toward the becoming a librarian with the professional situated the practice, and is the process librarian concretizes and realizes the ideal type of librarianship in the practice through adjustable interactive-process with environments.

This article or study subjectively explores actual experiences of a human book from a phenomenal viewpoint and is based on considerable amounts of reference literature and the collecting/analyzing of precedent theses data. Selecting specific research samples and conducting in-depth interviews were made to elicit the phenomenal marks or responses in human book experiences. Samples included a total of three human book practicing teachers belonging to Gyonggi Provincial Office of Education, who were picked out or chosen according to their rich performance experiences/activities over a two year period. They were interviewed in four different basic topic areas or parts sectioned out to the following: 1) actual needs of a human book; 2) experiences in human book; 3) changes of cognition to the human book; and, lastly 4) improvement in the application of a human book. As a result, the number of schools, the number of readers, and the number of people who participated in human book activities continued to expand. In addition, human book activities have become an opportunity for growth not only for participating readers, but also for the human book itself.

The strain localization of concrete is a phenomenon such that the deformation of concrete is localized in finite region along with softening behavior. The objective of this paper is to develop a plasticity and damage algorithm for the finite element analysis of the strain-localization in concrete. In this paper, concrete member under strain localization is modeled with localized zone and non-localized zone. For modeling of the localized zone in concrete under strain localization, a general Drucker-Prager failure criterion by which the nonlinear strain softening behavior of concrete after peak-stress can be considered is introduced in a thermodynamic formulation of the classical plasticity model. The return-mapping algorithm is used for the integration of the elasto-plastic rate equation and the consistent tangent modulus is also derived. For the modeling of non-localized zone in concrete under strain localization, a consistent nonlinear elastic-damage algorithm is developed by modifying the free energy in thermodynamics. Using finite element program implemented with the developed algorithm, strain localization behaviors for concrete specimens under compression are simulated.

This research regards that experiencing certain space according to looking through sensations of body will finally make visual perceptional experience to happen. Our bodies incorporate sensible experience along with interactions with surrounding environment while making movements. The analysis of Seongyojang in Gangleung through top and bottom, depth, movement and experience space which are Merleau Ponty's phenomenological space elements has led to the following conclusions. First, the up and down directivity inherent in Seongyojang has different directions in movements by the axis of plane. Second, the depth by the correlation between things and bodies shows the interactions with things and the depth of space rendered by the servants' quarters of '一字形' and the overlapping effect from the movement between buildings can be seen and felt. Third, mobility is focused on the surroundings for the movements of body and thing. Fourth, the experienced space remains as what it is and is experienced through the experience of traditional cultures. The temporality where the past and the present subsist is given with the application of the modern living pattern in the traditional space. That is, the space from the point of phenomenological view makes the visual-perceptual experience possible through the senses of body, with which the space is experienced and sensed. In other words, the space from the phenomenological viewpoint makes visual-perceptual experience possible through the senses of body so that the space may be experienced and perceived. Through this study, a new viewpoint toward Korean traditional space is expected to be discovered.

The year 1997 was when Korean Journal of Public Relations Research started to publish research articles. This study addresses the issue of theories in Korean public relations research. A total of 166 research papers are analyzed to see characteristics and changes during 2003-2012. Through this meta analysis, the researcher tries to see the big picture and discusses the right direction for the future of the public relations in many ways. Three different groupings were adopted to classify theories in the 10 year perion - 1. origins of theories(public relations field, related neighbor field, distant field), 2. target of analysis(individual, organization, society), 3. level of approach (systematic pluralistic, rhetorical, critical approach). According to the findings, though getting better, it was 'cold season' in public relations research because theories utilized in Korean public relations research were not very excellent qualitatively and qualitatively. Interdisciplinary approach is discussed.

The rapid motion of granular material is microscopically observed, and investigated by continuum theory. From the binary collision phenomenon two different times are introduced : flying time and contact time. The former says the non -stationary motion and at a same time the variation of bulk volume. The latter is operative by a delayed time during the contact and describes the elastic properties of granular material. With both times a dynamic constitutive equation is postulated for four state variables : dispersive pressure, viscosity, thermal diffusivity and energy annihilation rate. The balance laws of mass, momentum and energy which are represented through above four variabls, are applied to the model, in which due to the elastic property the relaxation and energy absorption are explained.

스퍼터링에 의해 증착된 박막 내 기계적 응력 발생 현상을 규명하기 위하여 활발한 이론적, 실험적 접근이 있었으나, 복잡한 플라즈마 증착환경 내에서 다양한 증착 파라미터로 인해 정확한 응력 발생 메커니즘에 대해 아직도 완벽한 규명이 되지 않은 상황이다. 본 연구에서는 몰리브데늄 (Mo)과 텅스텐 (W) 박막을 마그네트론 스퍼터링법을 이용하여 증착 시 발생하는 잔류응력 발생 현상에 대해 논의하겠다. Mo 박막의 경우 증착압력을 2.5 mTorr와 4.1 mTorr로 고정시킨 채 기판 바이어스를 0-250 V 간격으로 변화시킨 결과, 2.5 mTorr에서는 기판바이어스가 증가할수록 압축응력이 증가하는 반면 4.1 mTorr에서는 기판바이어스가 증가할수록 인장응력이 증가하는 것이 확인되었다. 이러한 반대 경향의 잔류응력을 발생시키는 기판 바이어스 효과를 확인하기 위하여 증착 파라미터 변경에 따른 박막 성장 거동 모델을 제시한다. W 박막은 준안정상인 ${\beta}$-상이 증착 초기(2.5 nm)에 형성이 되고, 증착 과정에서 열역학적 안정상인 ${\alpha}$-상으로 상변태 하였다. 상변태에 의한 부피 변화에 따른 잔류응력 발생의 분석을 위하여 X-ray 회절피크의 비대칭성을 분석한 결과 압축응력과 인장응력이 공존하고 있는 것으로 확인되었다. 본 연구결과는 스퍼터링 공정 시 높은 에너지를 가지는 중성화된 Ar과 스퍼터된 원자가 기판과 충돌 시 atomic peening effect에 의해 압축응력이 발생한다는 일반적인 이론과 상충되는 결과로서, Mo 및 W 박막 내 잔류응력 제어를 위한 방안을 제시한다.

In this paper, using statistical theory the basic concepts and the formulars of lower limit of detection were deasribed. Assuming that risks of 5% are acceptable (95% confidence level), lower limits of detection were calculated on the measuring apparatus for alpha, beta and gamma nuclides. Also, on the basis concepts of lower limit of detection, the MDA values were calculated for the radionuclides detected easily in the environment. These results make it possible to evaluate confidence limits on the radioanalytical results in the environmental sample.

Policy-related knowledge refers to a body of knowledge that bureaucrats and policy makers use when making decisions. In this study we conceptualize policy knowledge as intellectual infrastructure which helps to maximize efficiency with the viewpoint of policy ecosystem. The policy knowledge ecosystem covers people and organizations that participate in the production, distribution, and consumption process of the policy-related knowledge plus interactions between participants. We build the conceptual policy ecosystem model of comparative analysis, and analyze characters of e-government policy between Korea and U.S.A. The results suggest theoretical and policy implications focusing on the relevant policy knowledge is crucial for the sustainable development and growth.

This study analyzes the collision occurring in the daily life of the United States where diverse ethnicities live side by side, as portrayed in the film 'crash'. The analysis is followed by a counseling method necessary for a diverse society. To analyse the essence of conflict in the film, a convergence psychological analysis was conducted based on desire theory. The result was that the desire to survive and innovate always collided with frustration. This is because of the obstacles in real life that suppresses desire. The process of frustrated desires and their distortion was structurized. In the conclusion, a counseling method and theory with 'a recovery model that promotes change' was presented for problematic personalities that are entrenched widely in the United States about pain by conflict.
