This paper describes a design of graphical user interface for a simulated breeding tool with multifield. The term field is used here as a population of visualized individuals that are candidates of selection. Multi-field interface enables the user to breed his/her favorite phenotypes by selection independently in each field, and he/she can copy arbitrary individual into another field. As known on genetic algorithms, a small population likely leads to premature convergence trapped by a local optimum, and migration among plural populations is useful to escape from local optimum. The multi-field user interface provides easy implementation of migration and wider diversity. We show the usefulness of multi-field user interface through an example of a breeding system of 2D CG images.

This study puroses to grasp the change of dwelling space by the change of family organization according to the change of population in the rural area of suburbs of city that suppose to receive the influence of the city. The method of this study is to collect data about form village houses in monographs and reference books and study change factor of houses. To the selected village we will interview local inhabitants and officials and observe and survey the farm village houses by visiting houses. Through the research results we will know the change of population organization that cause the change of room utilization. We know that village pepole have living articles in dwelling space. We expect that the farm village houses will become city houses only in the dwelling space. So the suburban farm houses must be planned as in relation with the city.

Through the rapid growth of Korea for the effectiveness and rationalization of the use of land the development of the underground land is mostly needed. Especially I think that in the limited country(like Korea) when we consider that the population of metropolitan area is almost a third if a total population of this country it is time that we should consider the method of transfer for using of under ground not of on the ground from the legal or systematic recognition of the land. In this respect it is necessary that the person involved in the urban development (the person for architect urban development landscape architect and adminstratives) should pay much attention to the using of the underground spaces.

China which has 960km of domain area is one of the biggest countries in the world. Also China has a large population of 1,300,000,000 which are 25% of total world population and consist of 56 ethnic groups. In addition, History of China is immemorial and Confucianism of feudalistic and Taoism idea have effect on Chinese for a long time and architecture is influenced by them. Thus a large degree of variety, abundance, and uniqueness can be found in Chinese traditional dwelling. This research will be focusing on Sanapwon, a traditional housing in Beijing, which represents China's original and distinctive dwelling features. By looking at Sanapwon, we can learn the distinguishable characteristics of Chinese residential area and understand the concept of space. By looking closely at the worldly outlook, historical view, originality, and the spatial notion centered around human beings, many types of Sanapwon and its formation process have been examined Likewise indoor plane construction, and basic element of composition of space will help to study the whole of residing space.

We describe a formal approach to the construction of optimal classification rule for the two-group normal classification with equal population mean problem. Based on the utility function of Bernardo, we suggest a balanced design for the classification and construct the optimal rule under the balanced design condition. The rule is characterized by a constrained minimization of total risk of misclassification, the constraint of which is constructed by the process of equation between expected utilities of the two group conditional densities. The efficacy of the suggested rule is examined through numerical studies. This indicates that, in case little is known about the relative population sizes, dramatic gains in accuracy of classification result can be achieved.

In bioengineering field, current academic trends and informations on crystallization technology for bioproduct separation were summarized. It is essential for utilizing the crystallization technology to understand the fundamental phenomena of crystallization of crystal nucleation, crystal growth, crystal agglomeration and population balance for the design of crystallizers. In general, the crystal nucleation that the crystalline solids occur from the solution is analyzed by Gibb's free energy change in the aspect of thermodynamics and in the present paper the crystal nucleation models based on the above thermodynamics are summarized by their key characteristics. The crystal growth and agglomeration, which have been studied over 50 years and are essential phenomena for separation technology, are reviewed from their basic concept to most leading edge trend of researches. In the material and population balances for the designs of crystallization separation process, the analysis of crystallizers is summarized. Thereon, the present review paper will academically contribute the understanding the crystallization phenomena and the design of the crystallization separation process.

The aged population increasing rapidly, the population rate of over 65 years old was over 7.5% in 2000 in Korea and it means that Korea is aging society. Increasing participation of woman in public affairs, becoming a nuclear family and increasing old aged people who want to stand alone brought about more the old households. But the aged welfare accommodation are still insufficient and more facilities accommodating the aged should be built. 80.5% of people according to poll by the Ministry of Health and Welfare responded the support of the aged is a serious problem in Korea. This result indicates the reality that the system for the aged are unsatisfied. Although these situations made a new concept of 'silver-town' of the welfare facility for the aged, it is under a transition in the aspect of the social system and the architectural aspect as well. This study will select good examples among facilities in the metropolitan area, analysis space and propose resonable program.

Genome-wide association studies (GWAS) are designed to discover genetic variants such as single nucleotide polymorphisms (SNPs) that are associated with human complex traits. Although there is an increasing interest in the application of GWAS methodologies to population-based cohorts, many published GWAS have adopted a case-control design, which raise an issue related to a sampling bias of both case and control samples. Because of unequal selection probabilities between cases and controls, the samples are not representative of the population that they are purported to represent. Therefore, non-random sampling in case-control study can potentially lead to inconsistent and biased estimates of SNP-trait associations. In this paper, we proposed inverse-probability of sampling weights based on disease prevalence to eliminate a case-control sampling bias in estimation and testing for association between SNPs and quantitative traits. We apply the proposed method to a data from the Korea Association Resource project and show that the standard estimators applied to the weighted data yield unbiased estimates.

Equipment designer should consider how many people and what range of percentiles will be used as design criteria. The usual practice is to select some large range of the accommodation, such as 5th-95th percentiles. There is difficulty in defining 95% accommodation of population in complex design problems which involve several body dimensions. This paper develops the methods of constructing family of manikins which are validated for population accommodation. They are analyzed by the interactions or relationships between body dimensions. Proposed manikin family represents multivariate body dimensions. Moreover, nine manikin families are determined for representative Korean of 30-50 aged by proposed manikin family. Their 2-D CAD modelings are developed for bio-mechanical and ergonomic applications.
