급격한 사회변동을 경험하고 있는 한국사회가 인구변천의 마지막 단계에 진입하면서 인구관련분야의 정책의 핵심은 출산과 인구통제에서 노령인구의 문제로 옮겨지고 있다. 최근들어 국가가 자가부양(self-care)이나 가족부양(family care)을 보완하기 위해서는 공적 서비스(public service)가 확대되어야 한다는 주장들이 강조됨에 따라 노인부양규범이나 공적 서비스(public service)가 확대되어야 한다는 주장들이 강조됨에 따라 노인부양규범이나 의식의 현황 및 변환에 관한 이해의 필요성이 증대되고 있다. 본 연구는 1994년 보건사회연구원이 실시한 <노인생활실태조사>를 이용하여 노부모들이 어느 정도로 가족, 자신 그리고 국가를 바람직한 노후생활의 부양원으로 보는가를 알아 보고 있다. 다항로짓 모형에 근거한 분석결과에 의하면, 아들이 없는 노부모인 경우 가족이 노인을 부양해야 한다는 전통적인 견해가 약하고, 경제나 건강상 여건이 좋은 노인일수록 자가부양의 견해가 높은 것으로 나타났다. 한편, 경제적으로 열악한 상황에 있거나 건강상태가 양호하지 않은 노인들이 국가의 책임을 강조한다고 가정한 가설은 본 연구결과 지지 받지 못했다. 본 연구의 목적은 정책적 함의나 추후연구를 위한 제안 등은 결론에서 다루어지고 있다.

The science of toxicology is the understanding of the mechanisms by which exogenous agents produce deleterious effects in biological systems. The actions of chemicals such as drugs are ultimately exerted at the cellular and gene levels. Over the past decade. several in vitro alternative methods such as cultured cells for assessing the toxicity of various xenobiotics have been proposed to reduce the use of animals. In this workshop three advanced methods will be presented. These methods are novel important models for toxicologic studies. Dr. Tabuchis group has establishcd two immortalized gastric surface mucosa cell lines from the pminary cultore of gastric fundic mucosal cells of adult transgenic mice harboring a temperature sensitive simian virus 40 large T-anugen gene. As the immortalized cell lines of various tissues possess unique characteristics to maintain their normal functions for several months, these cell lines are extremely useful for not only toxicity testing but also pharmacological screening in new drug development. Professor Funatsu have studied the formation of spherical multicelluar aggregates of adult rat hepatocytes(spheroid) having tissue like structure. The sphcroid shown thre is a prototype module of an artificial liver support system. Thus, the urea synthesis activity of the artificial liver was maintained at least to days in 100％ rat blood plasma. Dr. Takezawa and his coworkers have developed a novel culture system of multicellular spheroids considered 〃organoids〃 by utilizing a thermo-responsive polymer as a substratum of anchorage dependent cells. His final goal is to reconstitute the organoids of various normal organs, e.g., liver, skin etc. and also abnormal deseased organs such as tumor.

Purpose: The purpose of this study was to understand the life of newly appointed professors of nursing by exploring the meaning and essence of their academic work and life experience. Methods: The participants consisted of 11 newly appointed female full-time professors with less than five years of experience who had been purposely sampled from three or four-year nursing colleges. Data were collected from October 2010 to December 2011 through the face-to-face interview and phone interview. Thematic analysis was conducted using hermeneutic phenomenological methodology. Results: The findings were classified into seven themes: 'Starting feeling hope and delight', 'putting sustained energy into lecturing and training', 'struggling in the tense atmosphere where assessments are often conducted', 'gaining courage in an associated relationship network', 'experiencing confusion of the identity as a professor', 'seeking compromise, handling their work and housework', and 'shedding new light on reality with self-awareness'. Conclusion: This study is significant in that it offered the foundation for the creation of human resources networks and mentoring programs that help newly appointed professors to effectively adjust to university society on the basis of the sympathetic understanding of and support for their life.

Surface crack detection is an important aspect in the quality control process of egg markets. The acoustic vibration of an egg could be used as a critical factor in evaluating the eggshell quality. The mode shape indicates the egg vibration behavior at different locations with respect to the input impulse and provides important information for the optimum sensor location to obtain the desired acoustic measurements. Theoretical analysis and experimental measurements were conducted to determine the acoustic vibration modes in eggs. The resonant fiequencies of the first and second resonance mode of intact eggs were found to be distributed between 2kHz and 7kHz range. The measured mode shapes of an egg were similar to theoretical shapes of homogeneous, elastic spheres. An elliptical deformation at the equator ring of the egg was observed. The frequency peak of this mode was dominantly present in the frequency spectrum of an intact egg impacted at its sharp position. The mode shapes related to the first resonant frequency of an egg shelved that the optimum location for the measuring sensor was the 180 degrees position. A optimum location for the egg support was found to be the 90 degrees position having the smallest vibration magnitude.

Purpose: This study aimed to determine the levels of burnout, self-efficacy, intention to stay, and organizational citizenship behavior (OCB) among nurses in small- and medium-sized hospitals, and factors related to nurses' OCB. Methods: A targeted sampling method was adopted, whereby 185 clinical nurses employed at 1 of 4 hospitals were enrolled in the study. OCB was measured with a tool developed by Podsaoff et al. Associated factors, including nurses' general characteristics, burnout, self-efficacy, and intention to stay, were measured using a structured survey. Data were analyzed by frequencies, t-test, ANOVA, Duncan's multiple test, Pearson Correlation Coefficient and multiple stepwise regression. Results: Levels of OCB in nurses was on average 3.52 on a scale of 1 to 5, exhibiting a positive correlation with self-efficacy and intention to stay, and a negative correlation with burnout. The final related factors were self-efficacy, burnout and intention to stay with a predictive and explanatory power of 52% for OCB. Conclusion: To increase the level of OCB of nurses, an environment in which such behavior is encouraged needs to be established by introducing measures related to administrative support and task efficiency that reduces mental burnout, while increasing self-efficacy and intention to stay.
