Today, there have been more museums with architectural freeform structure. From an academic perspective, that caused a change in the paradigm of the genealogy of architectural forms. Accordingly, it has been required to find whether the freeform architecture influences an exhibition space. Therefore, in order to analyze the correlation between freeform architecture and exhibition space, this study looks into the tendency of actual freeform architecture through case analysis after 2000. An exhibition space of museum serves as a socially, culturally, and locally symbolic icon and has the function of delivering information to viewers through the aesthetic presentation of articles on exhibition. This study is meaningful in the point that it drew the conclusion of the correlation between freeform architecture and exhibition space in order to infer that a freeform exhibition space is more effective at viewers' spatial experience. The method and results of this study are presented as follows: Firstly, literature survey on the concept of the freerform architecture of museum and the classification of architectural forms was conducted and previous studies were analyzed in order to establish criteria. Secondly, a case study was conducted through visits to Singapore, Germany, and the Netherlands in order to look into the current state and characteristics of freeform architecture and exhibition space. In this case, Karel Vollers' architectural freeform criteria were used for analysis. Thirdly, to prove the correlation between freeform architecture and exhibition space, each case was cross-checked on the basis of Karel Vollers' architectural freeform criteria and freeform exhibition classification, and then results were drawn. The study results are presented as follows: Firstly, EX(angle, ortho) of freeform architecture had a significant correlation with the diagonal form of exhibition space. That was proved 92.3% accurately more in the Netherlands and Germany than in Singapore. However, the curve form of exhibition space had a unclear correlation. In Singapore case, the curve form correlation was made through RO, FR, and TW. Secondly, freeform architecture had complex-typed combination with the diagonal and curve forms of exhibition space. In particular, N-02 and G-02 had a combination form, basically EX, and partially various forms so as to induce the complexity of free form. As such, architectural freeform makes it possible to achieve infinite transformation in various combinations. For responses, combinational approaches are required in multilateral ways. Based on this study, it will be planned to analyze the correlation between freeform architecture of museum and exhibition presentation.

This article addresses the 2nd Korean consensus conference on cloning that was held by the Korean National commission for UNESCO in 1999. Though previous perspectives recognized the conference as a new citizen's participatory institution. they do not consider that it contains the ideal of deliberative democracy. This article notes that the citizens participated directly and handled the important social agenda through debate in the consensus conference. The consensus conference is another democratic form derived from preference aggregating democracy in the sense that it basically depends on public judgement of the citizens. This consensus conference has the historical meaning because it is in fact the first experiment of deliberative democracy in Korea. 1) We examine the theoretical foundations of consensus conference. They are social constructionism of science, the tradition of societal debate, and deliberative democracy. 2) We explore what deliberative democracy is. It is different from aggregating preference democracy in the sense that it depends on public judgement rather than private preferences. 3) We investigate the features and meaning of deliberative democracy which has experiment on the conference. In the Consensus Conference it was observed that citizens changed their preferences and went forward to developing their view of community as a result of the process of deliberation. It can be said to confirm the significance of deliberative democracy. However, it is simultaneously an opportunity to clarify some problems of deliberative democracy. First of all, it shows that there were hierarchies within the citizens' panel as well as between the citizens' and the specialists' panels. Secondly, there are difficulties in expressing the value of life in argument or discourse. Also, we need the institutional efforts concerning future generations and nonhuman beings in the respect that cloning relates to them.

This study investigated several cases of interactive learning mediated by exhibits in a natural history hall during visits by middle school students. Five visiting cases were selected, in which visitors engaged actively in the interactions between them. Each visiting case was analyzed in terms of visiting discourse register and the modes of interaction in order to understand both visitors' meaning-making processes through the discourse flow and the characteristics of visiting discourse according to the features of exhibits. Results were as follows. The information provided in the exhibits was used as THEMEs in visitors' discourse and the visitors presented their information on the THEMEs as RHEMEs. The visitors made their own meaning for the exhibits by exchanging their information with each other. Interrogative sentences on the exhibit panels allowed visitors to make arguments. Similar exhibits displayed together helped visitors to compare those exhibits. These two features of the exhibits facilitated visitors' meaning-making processes in the natural history hall. The modes of interaction between visitors mediated by the exhibits showed that the information itself from the exhibits as well as visitors' opinion on the exhibits were frequently used as the elements for in-depth cognitive social interactions that allowed the visitors to construct meaning. Based on these results, we discussed that understanding in detail how visitors choose information from exhibits and construct visiting discourse is very important to improve visitors' collaborative science learning at a natural history hall.

Inquiry became an essential methodology in science education. Recently, argumentation becomes more important in inquiry, but inquiry-based teaching in school science would not provide enough opportunities for students to have voluntary and active interactions during inquiry activities. Informal science learning can be an alternative for authentic inquiry. Accordingly, this study aims to find interaction patterns in dialogic inquiry of junior high school students in small groups in the natural history gallery. Inquiry elements and interaction patterns are analyzed with 42 dialogues of 13 small groups. As a result, seven interaction patterns are identified. First, five major interaction patterns were drawn as follows; Sharing questions, asking questions and simple response, asking questions and simple explanation, asking questions-simple explanation-(collecting data)-data based explanation, and asking questions-collecting data-data based explanation. Second, pattern 2, 'asking questions and simple response', is subdivided into three categories; passive and/or evasive response, inaccurate response, and repeated patterns of asking questions-simple response. The results of the study provide different patterns of dialogic interactions in a small group inquiry in informal contexts from formal contexts, and provide foundations to understand middle school students' interactive dialogues of inquiry occurred in the natural history gallery.

The trust toward the researchers and their study activities in society has faltered, in the wake of the paper fabrication event of researcher, Hwang Woo-Suk's doctor research team. After the event, researcher community and scientific community have experienced many changes through the self-reflection or the process of insight meditation. Until now, we have experienced that when researcher community leads the way to try to show their efforts to eliminate the raised doubts throughly, the public support toward researcher community and the trust in its study activity have not faltered. Nevertheless, the path for the researchers to go is still far and rough because the opposite cases coping with research misconducts passively are much more. Therefore It's urgent that misconducts in the research and learning should be avoided from unnecessary overinterpretation. To practice it, above all it's important how well researcher or learner should be equipped with a system where decision is made autonomously and reasonably, regardless of the interests from all fields including politic, economic and social etc. It's also required that their systems should be meticulous enough to prevent such irrationality in advance before the misconduct instances are depreciated. In this context, I will investigate the reason why research and development on norms in research ethics and learning ethics is meaningful, not in a posteriori but a priori dimension, as the way to have researcher and learner prepare autonomous self-purification systems. It's essential that for the progress of an obvious argument, first, what research ethics and learning ethics are should be established and defined distinctly(2). Then in the process, it is also examined why research ethics and learning ethics need norms(3). Subsequently I will conclude the paper, arguing the reason why research ethics and learning ethics should be justified(4), if the norms in research ethics and learning ethics can be formulated(5).

A new construction methodology has been proposed on a scientific basis to reason a rational explanation for the structure and the present configuration of Chum-Sung-Dae. This is because there is no way to otherwise explain the gap between our expectation that the people in Shilla are assumed to be and the problems, such as the use of a temporary supporting structure including falsework, the use of a conveying device for stonework and the practice of soil fill, raised when the construction method in nowadays is applied to the structure. Furthermore, it is because the questions, such as the difference of an azimuth angle between the southward opening and the square podium, the skewed circular plan in layers of the body, misalignment between neighboring layers of the body, disagreement between the inclination due to slight sidesway and the eccentricity in each layer of the circular body, perfectly aligned vertical and horizontal joints and the existence of soil fill, raised from the present configuration of Chum-Sung-Dae, also require a reasonable explanation based on scientific evidences, if any. Therefore, the proposed new construction methodology, in which the soil hill outside as well as the soil fill inside the Chum-Sung-Dae may have been utilized as a temporary scaffolding system for construction, is the highly probable one that the builders of Chum-Sung-Dae might have inevitably employed. The existence of great tombs, scattered in Hwang-Nam-Dong close to Chum-Sung-Dae, implies that the people of Shilla might have accepted the proposed new construction methodology as a natural one.

In every society, citizens must decide how to punish criminals, uphold the virtue of justice, and preserve the security of the community. In doing so, the members of society must ask themselves how they will punish those who carry out the most abhorrent of crimes. Many common responses to such a question is that death is an acceptable punishment for the most severe crimes. But to draw some theoretical distinction between a crime that deserves incarceration and a crime that is so heinous that it deserves capital punishment is subject to three errors. First, what possible line could be drawn? To decide on a particular number of deaths or to employ any standard would be arbitrary. Second, the use of a line would trivialize and undermine the deaths of those whose murderers fell below the standard. Third, any and all executions still are unjust, as the State should not degrade the institution of justice and dehumanize an individual who, although he or she has no respect for other human life, is still a living person. Simply put, all murders are heinous, all are completely unacceptable, and deserve the greatest punishment of the land; however, death as punishment is inappropriate. Also, while this article arrives at the conclusion that the death penalty is an inappropriate form of punishment, I have not offered an acceptable alternative that would appease those who believe capital offenders deserve a punishment that differs in its quality and severity. This is a burden that, admittedly, I am unable to meet. I finally conclude that the death penalty is unjustified retribution. This is the only claim that can effectively shift the intellectual paradigms of the participants in the debate. The continued use of the death penalty in society can only be determined and influenced by the collective conscience of the members of that society. As stated at the outset of this article, it is this essentially moral conflict regarding what is just and degrading that forms the backdrop for the past changes in and the present operation of our system of imposing death as a punishment for crime.

The main purpose of the research is to illustrate the value of the spatial statistical approach to residential differentiation by providing a framework for exploratory spatial data analysis (ESDA) using a local spatial separation measure. ESDA aims, by utilizing a variety of statistical and cartographic visualization techniques, at seeking to detect patterns, to formulate hypotheses, and to assess statistical models for spatial data. The research is driven by a realization that ESDA based on local statistics has a great potential for substantive research. The main results are as follows. First, a local spatial separation measure is correspondingly derived from its global counterpart. Second, a set of significance testing methods based on both total and conditional randomization assumptions is provided for the local measure. Third, two mapping techniques, a 'spatial separation scatterplot map' and a 'spatial separation anomaly map', are devised for ESDA utilizing the local measure and the related significance tests. Fourth, a case study of residential differentiation between the highly educated and the least educated in major Korean metropolitan cities shows that the proposed ESDA techniques are beneficial in identifying bivariate spatial clusters and spatial outliers.

This study is concerned with providing a reliable procedure of calibrating a set of places specific distance parameters and with applying it to U.S. inter-State migration flows between 1985 and 1900. It attempts to conform to recent advances in quantitative geography that are characterized by an integration of ESDA(exploratory spatial data analysis) and local statistics. ESDA aims to detect the spatial clustering and heterogeneity by visualizing and exploring spatial patterns. A local statistic is defined as a statistically processed value given to each location as opposed to a global statistic that only captures an average trend across a whole study region. Whereas a global distance parameter estimates an averaged level of the friction of distance, place-specific distance parameters calibrate spatially varying effects of distance. It is presented that a poisson regression with an adequately specified design matrix yields a set of either origin-or destination-specific distance parameters. A case study demonstrates that the proposed model is a reliable device of measuring a spatial dimension of migration, and that place-specific distance parameters are spatially heterogeneous as well as spatially clustered.

Mammary epithelial cells contain a subpopulation of cells with a large proliferativ potential which are responsible for the maintenance of glandular cellularity and are the progenitor cells of mammary cancer. These clonogens give rise to multicellular clonal alveolar or ductal units(AU or DU) on transplantation and hormonal stimulation. To isolate putative mammary clonogens, enzymatically monodispersed rat mammary epithelial cells from organoid cultures and from intact glands are sorted by flow cytometry according to their affinity for FITC labeled peanut lectin(PNA) and PE labeled anti-Thy-1.1 antibody(Thy-1.1) into four subpopulations : cells negative to both PNA and Thy-1.1(B-), PNA+cells, Thy-1.1+cells, and cells positive to both reagents(B+). The in vivo transplantation assays indicate that the clonogenic fractions of PNA+cells from out-growths of organoids in primary cultures for three days in complete hormone medium(CHM) are significantly higher than those of cells from other subpopulations derived from cultrues or from intact glands. Extracellular matrix(ECM) is a complex of several proteins that regulated cell function ; its role in cell growth and differentiation and tissue-specific gene expression. It can act as a positive as well as a negative regulator of cellular differentiation depending on the cell type and the genes studied. Regulation by ECM is closely interrelated with the action of other regulators of cellular function, such as growth factors and hormones. Matrigel supports the growth and development of several different multicellular colonies from mammary organoids and from monodispersed epithelial cells in culture. Several types of colonies are observed including stellate colonies, duct-like structures, two- and three-dimensional web structures, squamous organoids, and lobulo-duct colonies. Organoids have the greatest proliferative potential and formation of multi-cellular structures. Phase contrast micrographs demonstrate extensive intracellular lipid accumulation within the web structures and some of duct-like colonies. At the immunocytochemical and electron micrograph level, casein proteins are predominantly localized near the apical surface of the cells or in the lumen of duct-like or lobulo-duct colonies. Squamous colonies are comprised of several layers of squamous epithelium surrounding keratin pearls as is typical fo squamous metaplasia(SM). All-trans retinoic acid(RA) inhibits the growth of SM. The frequency of lobulo-ductal colony formation increased with the augmentation of RA concentration in these culture conditions. The current study models could provide powerful tools not only for understanding cell growth and differentiation of epithelial cells, but also for the isolation and characterization of mammary clonogenic stem cells.
