Yanji city in China is a city most populated with Korean-chinese. This study is to examine architectural planning characteristics for Korean-chinese Elementary schools in Yanji city. Currently, this city includes nine Korean-chinese schools. This research has been processed with regards to three broad aspects. Firstly changing processes of school systems, secondly local distributions and networks of school facilities, and thirdly site plans, floor plans and elevations of school buildings were analyzed and examined for finding their characteristics. For this study, seven Han-chinese Elementary schools were also analyzed. The study result are as following: 1. Korean-chinese schools have followed national education policies and also maintained Korean-chinese native education methods. The schools have undergone merger and separation with Han-chinese Elementary schools. Three Korean-chinese Elementary schools in Japan Colonials, two schools in the period of the Republic of China foundation and its growing, and four schools in 1980s were founded. 2. Yanji city administers the networks of Korean-chinese school districts and Han-chinese districts separately. All school districts apply to lkm standard as attending distance. The networks are adjusted as per population change. 3. The characteristics of buildings' site plans, floor plans and elevations are simple. Layouts of the schools are - type or -type centered playground. Building plans show one side corridor type and 5 stories mostly. Elevations stress central parts. Various forms such as finger types do not appear in mass planning since the school curriculum and extracurricular activities are not seemingly active. Han-chinese Elementary schools have similar conditions.

The purpose of this study is to analyze the distribution structure and the logistics system of light petroleum products from the spatial perspectives. The consumption structure of petroleum products has been changed since the mid 1980s. The growth rate of consumption for light products has been much faster than those of heavy products. The distribution structure of the petroleum products is hierarchically established by refining companies, agencies, and gas stations. The petroleum products agencies are distributed unevenly over the country, and the number of gas stations per one petroleum agency are very differentiated by the region. The light products are directly transported from refining factories to oil storages and then are carried to gas stations. According to the locational characteristics, oil storages which play a key role in the logistics system are categorized into three type. The first type is demand-oriented oil storages which are located near or in the large cities to supply the light petroleum products. The second type is harbors-oriented oil storages which are located within harbors. The third type is railway-oriented oil storages which are located along railway stations. In this study, the thresholds of one oil storage and one gas station are calculated based on the size of supply territory for each oil storage. The average number of population demand that allow a oil storage to stay in business is 1.9 million and average number of cars are 477,200.

This study aims not only to examine the globalization, imformationization, and networking as background of knowledge-information-based society, but also to clarify the research fields of 'geography of knowledge' and further research themes for economic geography in a knowledge-information-based society. As a result of globalization, the degree of regional disparity, which had decreased with neoliberal policy in Europe and America in 1980's, has increased in early development states such as China and Eastern European countries. In opposition to the globalization that has led to increasing regional disparities at a global scale, many scholars argue that grassroots globalization or globalization from below is needed. Based on a pessimistic view on globalization, many maintain that unequal access to information has enlarged the gap between rich and poor. They also argue that the study of the geography of poverty is crucial in oder to solve the problem of bipolization. According to the world system theory, spatial grasp of commodity chains, actors' diversities, flows towards innovation in learning knowledges, and geographical, organizational, and institutional proximities are intertwined. Because these elements make significant influences each other in social networks, the interrelationships among those elements should be carefully considered. A 'geography of knowledge' deals with manufacturing, finance and service, media, cultural, and creative industries. Former researches in economic geography have tended to deal with those industries separately without attempting to make meaningful linkages among discussions on those industries.

Due to a rapid in automobiles since the 1980’s, the concentration of NO, and HC has also increased along with cases of VOCs. These air pollutants have created $O_3$ concentration, which cause a harmful effect to the human health. This issue has become a subject of great public interest. For this paper, to compare the concentration of $O_3$, NO, N $O_2$ between the rural and urban area in the winter, the concentrations of each have been measuredevery hour during Jan.~Feb. 2000, 1998, respectively. To calculate the Photochemical Steady State, $\Phi$= $J_{N O_2}$[N $O_2$]/ $k_1$[NO][ $O_3$], temperature and $J_{ N O_2}$ has been determined. The NO concentration in the rural are showed at below 10 ppb while the NO concentration in the urban area showed maximum value of 90~120 ppb. But the $O_3$ concentration in both areas showed less than 30 ppb. The reason is that the N $O_2$ photodissiciation rate is low due to the temperature being below 2$^{\circ}C$ and less than 60 degrees in the solar zenith angle during the winter time, which makes the $O_3$ concentration in both areas, similar in the concentration level. N $O_2$ photodissociation rate in both ares showed maximum value of 3.0mW/$\textrm{cm}^2$. Values of $\Phi$ determined from the rural area was consistently the unity, approaching 1. But values of $\Phi$ determined from the urban was roughly higher than unity, approaching above 1or 2 for clear sky-high sun(10:00~16:00).

The weight of elderly people in Korea has been increasing. Statistics show that the percentage of the elderly people in Korea was 3.1% in 1970; 3.8% in 1980; 5.1% in 1990, and 7.2% in 2000. Based on this trend, thus, the number of elderly people could be estimated to be 14% of the whole Korean population in 2018. This reveals that Korea is entering a super-aging society with remarkable fast pace. In such a change, the statistics related to elderly people driving license and the occurrence of traffic accidents are showing a noticeable numerical value. The number of traffic accident fatality in Korea ranks the highest value in OECD Countries. However, the research on old drivers in the nation is going on partially centering on system improvement and management scheme. Thus, first of all, researches about the linkage & characteristics between the driving behavior of old drivers and traffic accident should be implemented, in order properly to draw system improvement and management scheme for the old drivers. Therefore, the focus of this study is the influence model for discerning the severity of the age-old-caused traffic accidents by inquiring into the relation between the Driving Aptitude Test items that make it possible to measure their behavioral characteristics and influential factors by age group on the basis of the data on traffic accidents. The analysis results can be used as basic data for suggesting the behavioral research and countermeasure for traffic safety and its management for old driver in preparation for the aging society.

This study examines the competitiveness of urban industrial structure and its changing characteristics. Cluster analysis of Arizona towns based on economic functions revealed the changing characteristics of urban functions over time. The relationship between the changes of urban functions and industrial competitiveness was confirmed through shift-share analysis. The level of industrial specialization has become more closely related to urban size in terms of both population and employment, but the relationship between metropolitan location and specialization level is not clear. Also, it is validated that the economies of Arizona towns have become more diversified and, consequently, have tended to converge toward the state average in industrial structure over time.

Scribble methodology is developed from the modernist's effort of pursuing the free expression and painterlyness And in modernism period usual abstract mode is made by simple plastic ingredients. One of them is Scribble way. In the period of postmodern, the Scribbling is confused with destructive methodology like Iconoclasm, Vandalism and scribbling. Lucio Fontana and Robert Raushenberg had developed these methodology and made new direction in $1960\sim1970$. After 1980, there had been graffiti movement similar to scribbling in germany. There had been developed many kind of scribble methodology, in each artist and be prolonged destroy the price of our usual concept. These Styles are able to discerned as follows. Firstly, in case of Cy Twombly, he used very allusive signifier, which contain different motives come from the ancient ruins or myths. The methodology follows multi-codified meaning relationship. Secondly, the methodology was developed by Jean Michael Basquait as the type of Hispanic scribbling for ebony peoples and by Keith Harring as the type of Cartoon image of Mass-media based on technology. Thirdly, the multi-meaning style was developed by David Salle as the type of destructive methodology which are the ambivalent images conjoined difference time and term and by Gigmar Polke as the type of mixture of abstract and realistic shapes together which are based on the aesthetics which is based on pessimistic sight for contemporary civilization. It means the methodology is based on the multi-codification of postmodern semiotics. So the scribbling mode is subjected as important as the changedness of late 20th century painting developments.

This paper presentss flux-to-dose conversion factors for neutrons and gamma-rays based on the concept of the maximum absorbed dose. Neutron flux-to-does-rate conversion factors for energies from 2.5$\times$10$^{-8}$ to 20 MeV are presented while the conversion factors for gamma-rays are given in the energy range of 0.01 to 15MeV. Flux-to-does-rate conversion factors, which were calculated under the assumption that the radiation energy distribution has nonlinearity in phantom, are different from those values obtained by monoenergetic radiation. Especially, these values obtained here were determined for the cross section libray such as DLC-23, DLC-27, and DLC-31. The flux-to-dose-rate conversion factors obtained in this work are in a good agreement with the values presented by American National Standard Institute (ANSI) N666. These results are used to calculate the dose rate distribution of neutron and gamma-ray in any radiation fields, and will be useful for the radiation shielding analysis, radiation protection and radiation dosimetry concerned with problems of continuous energy distribution.

About 6 to 8% of the eggs annually produced are broken or cracked between the hen and the consumer's carton. The majority of this breakage is due to interrelationships between egg shell quality and the many biological, environmental and managerial factors which have been individually identified as affecting breakage. Some of the factors associated with shell damage discussed in this review include age of hens, temperature ana humidity of the laying house, design of the cage systems and of the cage floors, type of material used to manufacture the cages frequency of daily egg collection in the laying house and, Probably most important, the frequency and quality of handling equipment maintenance. Age and genetic constitution of the hens, environmental temperature, and design and quality of equipment maintenance are the major factors that influence shell breakage. There is a curvilinear relationship between shell quality and shell breakage which explains why small changes in shell quality may be associated with large changes in the incidence of breakage. Published data indicate the incidence of breakage may range from as low as 1 to 2% to 35% or more for other egg producers.
