  • The aim of this research was to compare and analyze the children's ideas on evaporation and condensation between pre- and post-intervention. Forty-eight children from six elementary schools in Seoul and Kyung Ki provinces were sampled by stratified random sampling. A set of structured activities was then provided which allow children to explore evaporation and condensation phenomena. All of these activities had a preliminary phase which required the child to predict or speculate on evaporation and condensation using their existing knowledge. These structured activities on evaporation and condensation were reviewed by three professors and eigth primary school teachers. Their comments were used to revise the original contents of the structured activities. The data analysed were gathered by the questionaire and the interview. Pre- and post-intervention data related to evaporation and condensation were collected by the same teacher, and analysed into the same category scheme. Data coding was carried out several times by the researcher to ensure reliablity. Data collected were then classified and analyzed according to the types of children's ideas. The findings of this study were as follows: Results of this study showed that the the vocabulary used to describe the evaporation phenomena varied according to the context, and the scientific term "evaporated" was more frequently used by the older children after post-intervention. But everyday terms such as"dried up","disappered", "gone up" were also used by children as much as the level of pre-intervention. Scientific conception on the location of evaporated water, the factor of evaporation, the ideas about getting the water back and assumption about the physical state of the missing water has been increased for the most of the children after intervention. It was found that the intervention using was effective SPACE strategies regardless of the grade level of the children.

  • Since Modern period which is characterized by the governing of technology and capitalism, the production and aesthetics of building became a main issue of architectural discourse. Morever, Modern architecture tends to be a kind of media in which the visual image of building plays a far more important role than building itself. Institutionalized discipline of Architecture in modern system set aside the dwelling aspect of building and destructed close relationship between dwelling and building. This study analyzes the essential meaning of dwelling with a viewpoint of building and vise virsa in order to have a deep reflection on contemporary architecture and modern crisis of dwelling. For this purpose this study first reviewed linguistic and mythical narratives on the origin of dwelling and building. Secondly, reviewed the thought of Heidegger on dwelling and building and his thinking on authenticity of dwelling. Thirdly, reviewed drastic change of idea and reality of dwelling recent days, especially from settlement to nomad. Lastly reviewed E. Levinas' thinking on bodily dwelling or primordial mode of dwelling before poetic dwelling of Heidegger. With these review we can figure out following things on dwelling and building. Physical building or its visual image can not take the place of dwelling in itself. Dwelling and Building happens simultaneously and understood as an event in life world. Today's alienation of dwelling from building reduced our conception of architecture to a physical setting and mere technique. Building must be a ontological and cultural phenomenon beyond physical building. Nomad in this age of information and globalization may be a new mode of dwelling. But it can not exclude traditional way of dwelling on concrete space, because human being as a physical being can not abandon dwelling place that gives a primordial comfort with and within our body.

  • The changing Agenda of the family policy is to be influenced by many factors. The structural change of population and aging problem in modern society are generally included in main factors which produce political needs. Therefore, migrant family is recognized as a alternative which is to resolve the socioeconomic problems of aging industrial societies. In Germany, Gerhard Schroeder who leads the SPD governs since 1998. The Schroeder's new conception of welfare policy is known as the third way("neue Mitte") which the social economic structure intends to neo-liberalistic trend. The concern on the welfare policy for the migrant families has grown recently in neo-liberalistic age, but research on german welfare policy for migrant families is very limited in quantity and Depth. The main purpose of this study is to examine how the welfare policy for the migrant families of Schroeder-government has been developed in Germany. And this paper evaluates the results of transforming policy. Based on this evaluation, this paper attempts to be manifest the problem of korean family policy for the migrant population and to find out implications of german model.

  • The aim of this study was to analyze post-weaning reproductive performance of Large White sows in relation to season, parity and their lactation performance under tropical conditions in Guadeloupe (French West Indies, $16^{\circ}$ Lat. N, $61^{\circ}$ Long. W.). This work was based on data recorded in the experimental unit of INRA from January 1993 to December 2003. Two seasons were determined a posteriori from climatic parameters recorded continuously in a station close to the experimental unit. Mean ambient temperature was higher during the hot season than the warm season ($26^{\circ}C$ vs. $24^{\circ}C$) but relative humidity was comparable for both seasons (i.e. 87% on average). Season had a significant effect on all reproductive parameters analyzed. Primiparous sows weaned in the hot season had a higher probability of a prolonged weaning to estrus interval, WEI (odds ratio was 4.1; p<0.01) but multiparous sows were not affected. A higher probability of a prolonged weaning to conception interval, WCI (odds ratio >2.5, p<0.01) and a lower subsequent farrowing rate (-10%, p<0.01) were found for sows weaned in the hot season. A higher daily feed intake during lactation reduced the probability of a prolonged WEI (p<0.05). Body weight and average back-fat thickness at farrowing affected WEI and WCI (p<0.05), whereas body weight and average backfat thickness change in lactation did not. This study confirms the negative effects of the hot season on primiparous reproductive performance. It also indicates that lactation performance influences sow non-productive period.

  • This paper aims to provide a context-specific interpretation on the shifting process of in-house R&D spaces in a large Korean firm in the context of rapidly changing markets and technology. Drawing on the case study of LG Electronics Company, one of the Korea's flagship companies, I examine the causes and mechanisms leading to a shift in domestic R&D spaces and the nature of learning processes between R&D teams and between R&D and other organizational units, particularly manufacturing. It appears that the current reshaping processes of domestic R&D spaces in LGE focus more on the clustering of core R&D laboratories than the geographical integration of conception and execution. However, it should not simply be viewed that such a move would be reduced to the linear model of innovation and organizational learning. Instead, it involves the firm-specific mode of regulating organizational competences. As contextual variables to induce such a firm-specific mode of organizational change, I consider the spatial form of organization, the spatial sources of knowledge and learning, and the powers of relational learning that can be made between distanciated actors and teams.

  • The purpose of this study is to research the symbolistic values of western beards' style in the twentieth century. Namely, it is to consider the relationship between social-cultural factors and aesthetic meanings of western beards' style. The contents are, firstly, studying the conception and the types of beard. A beard is the hair that grows on a person's chin, cheeks, neck, and the area above the upper lip. At the World Beard & Moustache Championships, there are moustache category (natural, english, hungarian, dali, fu manchu, freestyle), beard category (natural, musketeer, goatee, sideburns, freestyle), and full beard category (natural, garibaldi, verdi, van dyck, freestyle), Secondly, this paper is continued by researching the history of beard from the ancient to the present day, and thirdly, analyzing political dictatorship, social resistance and expression of personality, religious dignity, related with the change of world situation, the formation of postmodern anti-culture and pop-culture, and the coexistence of traditional culture. There are long and bushy full beards in some religions like Hinduism, Judaism and Islam. The meanings of their beards are purity, life and holiness. The beards of some politicians symbolize dictatorship. Namely, the chaplin of Hitler, the moustache of Hussein and the musketeer of Castro express strong power and charisma. In 1950s'-70s' subcultures, Hipsters' goatee, Bikers' horseshoe, Beat generations' goatee and Hippies' natural represent the lack of adaptability and social resistance. Also, the celebrities and artists like Ronald Colman, Clark Gable, Don Johnson, George Clooney, and Salvador Dali express freedom, personality, and taste with beards. For that matter, the symbolistic values of beards' style in the twentieth century are the religious dignity, the political dictatorship, the social resistance and the expression of personality. Today the beards' style is one of fashion items as well as a symbol of masculinity, customs and classes.

  • Shangwan(CV13), Zhongwan(CV12), Xiawan(CV10), Hefu(L14) and Taichong(LR3) which belong to Conception Vessel and stomach meridian are acupuncture points frequently used for healing gastrointestinal desease in oriental medicine. The present study was conducted to see the effects produced by combined acupuncture(A), electro-acupuncture(EA) and moxibustion using five acupoints which belongs to different meridians on serum gastrin level in rats. Electro-acupuncture (2 Hz, intensity; 10 times muscle twitch threshold) was applied for 30 minutes to Hefu(LI4), Taichong(LR3) under halothane anesthesia. Moxibustion ($1.6{\pm}0.3\;mg$, 5 times of a day) was applied during 3 days to CV10, CV12, CV13 under halothane anesthesia. Combined stimuli of acupuncture at Hefu(LI4), Taichong(LR3) and moxibustion at CV13, CV12 increased serum gastrin level significantly eventough combined simulus of moxibustion on CV 10 was not shown any change. And combined stimul of EA and moxibustion at experimental all groups were not shown any effects. These data suggest that effects of acupuncture and moxibustion are depentent with used acupoints and combination stimuli method.
