The purpose of this study is to identify the current status of the working poor and the factors that are influential to the working poor among echo boomers. This study is a secondary analysis using the data from the 7th analysis of the 2012 Korea Welfare Panel Survey, conducted by Korea Institute for Health and Social Affairs. This analysis considered Korean echo boomers born between 1979 and 1985. In our final analysis, we used 1,226 echo boomers who had the ability to work. For the analysis, the SAS/PC statistical program ver. 9.3 was utilized. The research findings are as follows; Firstly, of the working poor among the echo boomers, only 22% were in the state of poverty. Secondly, more echo boomers living in a metropolitan city, city, gun/urban-rural area and district than those in the Seoul were categorized as among the working poor; the same was true for those who lived in a free house than in a leased room or a room that was rented by the month. Thirdly, more echo boomers whose education level was high school graduate or less rather than college graduate or less or university graduate or more were categorized as among the working poor; this was also true for echo boomers whose employment type was temporary employment, self-employment, or unemployment rather than a full-time job.

The paper explores the return migration choice of graduates, which takes place during the transition from higher education to the labor market. Graduate students, after a short time in temporary migration to cities for studying, have to make a decision of returning back home or staying in migration in urban areas for working. Drawing on the mechanism identified in the literature on internal migration, this empirical research tests the effects of two factors: place attractiveness and social supports factors on graduates' decision to return migration to hometown. A binary logit regression analysis was conducted with data from 502 surveyed graduates in Hanoi, Vietnam. The analysis of the motives reported by graduates indicates that return migration decisions cannot be reduced to a single dimension. Perceived attractiveness of a region such as quality of living environment, job opportunities, and social context of individuals positively impact on student' decision to return migration after graduation. The research results imply that, in a collectivistic country like Vietnam, students' choice of future career is strongly influenced by their social context, and choosing a place to work is not simply a matter of earning a higher salary or enjoying better working conditions, but is also related to family issues.

The emphasis in environmental education for children should be on awareness, appreciation, and sensory experiences. By offering children opportunities to experience the elements of nature that surround them, teachers elevate children's comfort level and familiarity with the natural world. But many children have little contact with nature, because of urban living, hurried schedules, TV's attraction, and the low value most schools place on outdoor activities. So, teachers have to expand the real out-of-door experiences into the classroom by sharing and making accessible books focusing on nature and the natural environment. Namely, quality children's literature is an excellent vehicle for extending a particular experience or introducing new ones. Building on outdoor experiences through stories encourages children to explore more deeply what they have observed and experienced-concepts are reinforced, new knowledge gained, vicarious experiences provided. There are three-fold classification of environmentalism, especially environmental ethics, and three-aspects of the history in children's literature. The analytical results of this study are as follow. The environmental ideology in elementary Korean textbooks varies from 'egocentrism-didacticism' to 'ecocentrism-fantasy'. This finding has implication for selecting children's books and teaching environmental contents in elementary school. Therefore teachers and parents need to get ready to receive ecocriticism.

This study is aimed at investigating the compensatory education which was already implemented or is being implemented in the U.S.A. and Japan; and at studying the types of programs and their characteristics; and at sounding out the possibilities of the application of such programs in family and social conditions is Korea. In order to achieve the above mentioned objectives, the established items for the study are as follows: (1) Various types of early children's education (2) Programs of compensatory education for the disadvantaged Children (3) Head Start Program, Early Training Project and Montessori School (4) Integrated Preschool Programs (5) Day-Care Center for employed mothers We investigated the various compensatory education programs for the preschool children who are in economically, socially, culturally disadvantaged conditions. Head Start Programs were federally supported programs for preschool children and opened as summer programs in 1965 for the first time. The purpose of Head Start has been to give preschool children the kinds of experiences they need in preparation for school. The Head Start children were found to be significantly better prepared for school than the normal children. However, after six to eight months, their initial advantages had virtually. disappeared and then the simple problem with Head Start and other such programs was that little long-term good could be evidenced unless the high quality educational environment was maintained. Therefore, to solve this problem, three other programs were funded as part of the overall Head Start. These three programs are the Parent-Child Center, Home Start, and the Child and Family Resources Program. The Early Training Project for disadvantaged children was implemented by Klaus and Gray of Peabody College in 1962. The program was a field research study concerned with the development and testing over time of procedures for improving the educability of young children from low income homes. Its major concern was to study whether it was possible to offset the progressive retardation observed in the public schooling careers of children, living in deprived circumstances. Children, who were trained through the Early Training Project were superior to control groups in the test of IQ and vocabulary as well as linguistic abilities, and preparation for reading. This project showed the possibilities which could prevent preschool children from being disadvantaged socially, culturally and mentally. In 1907, Montessori School was established by Maria Montessori in Italy and her school program has been introduced at present to several countries in the world as one compensatory educations. She first began her experimental methods with retarded children, followed by disadvantaged children from the tenements of Rome. The Montessori approach futures a prepared environment and carefully designed, self-correcting materials. The Montessori curriculum presents tastes that feature sequence, order, and regularity, in addition to those that develop motor and sensory skills. She was interested in children's intellectual development and in developing good work habits. One of the latest developed programs for disadvantaged children is "Integrated Preschool Program" which has successfully integrated handicapped and nonhandicapped children. Several studies have showed that handicapped children in integrated school environments are accepted by and interact with their nonhandicapped peers. In fact, this program provides a number of potential, and perhaps opportunities for nonhandicapped children to serve as valuable resources in fostering the development of their handicapped peers. Next we turn to Japanese programs which are divided into two different types. One is Day-Care Center which was established by Child Welfare Law and the other is kindergarten organized by School Education Law. The kindergarten opened in 1876 and it has been part of school systems since 1947 by the implementation of education law, and the Day-Care Center which started in 1890 for the employed mothers. was changed into Day-Nursery by the enactment of child welfare law in 1947. The laws and operational regulations for the Day-Nursery were set up and were put in effect by the establishment standard acts of children welfare facilities, and the Day-Nursery has been operated in various types by the increasing demand, chiefly because of the socio-economical changes of family structures in both urban and suburban areas. Nursery education for physically and mentally disadvantaged children is for those who are blind, deaf and dumb, mentally retarded; physically disadvantaged by accidents or diseases. Montessori education in Japan was started in 1968 and many research groups for studying Montessori were organized. In 1977, Montessori remedial education society was also organized in which they started a number of studies; a study for developing materials; in-service training for the remedial education; and seminars and lectures, etc It is strongly suggested that we study the early educations that are being implemented in Japan and a variety of compensatory educations that were already implemented in the U.S.A. and modify them for the organization of our own model and properly accommodate them to our social needs.

Purpose: This article aims to explore the new town development paradigm against infectious diseases. The distribution of COVID-19 constricts economic activity. The high frequency of outbreaks of COVID-19 nationwide is due to neither malnutrition nor unhygienic environment. Research design, data and methodology: The research question starts with the idea that understanding the features of the outbreak of pandemic diseases could help public health authorities to better cope with upcoming risks in the future. We have employed a big data-based methodology to explore the outbreak of pandemic diseases. Also, an idiographic approach is used to describe the distribution of new towns against COVID-19. Results: The results demonstrate that the rapid spread of COVID-19 has had a strong impact on regional economies and urban development. It was found that there is a close relationship between infectious diseases outbreaks and new town development. Conclusions: The findings could be used to deal with new town development against infectious diseases better in other cities or countries as well. The distribution of COVID-19 may become an unexpected opportunity for a paradigm shift in the distribution of new town development to prevent not only an excessive concentration in Seoul, but also an imbalance between national and local development.

Education on the environment and plants offered by arboretum for today's people not only contribute to foster a better natural environment in urban region but also provide visitors with decent refreshment environment and beyond. In the study, the author undertook the observation on usage behavior and satisfaction model of arboretum visitors expect and investigated the facilities and programs to be offered by arboretum in order to propose the opinion regarding the service. For observation size of variables in a multiple regression analysis of variables is influencing satisfaction rankings walks the line of flow, the educational effect on the environment, cleanliness of the facility, visits pay, natural beauty, diversity of trees, accessibility and friendliness of staff, expansion of facilities in the arboretum and appeared as a complement. In case of visitor attribute, the residents living near the facility showed the highest visit frequency of more than 5 times, especially as part of taking a walk. This proves that the visit to arboretum is considered as part of everyday life, and thus a new program and walk path as well as movement route are needed to be developed for the visitors. In the question relating to the facilities and operation programs in Daegu Arboretum, particularly the requests by visitors, they responded that the establishment of cultural event, beautiful natural scenery, refreshment and convenience facilities is the most critical issue. In addition, the management on withered trees and bare lands is an urgent issue as well. In this sense, the Operation and Management Strategies based upon the visitor behaviors and model of satisfaction are needed to deal with the adoption of diverse events and festivals joined by local residents, ombudsman program, environmental program development for students and teachers within the region, negligent bare lands and withered tree replacement, and cafeteria facility improvement and supplement as well as the bench marking of other facilities than arboretums located in other regions. These items are thought to be sufficiently dealt with by Daegu Arboretum having no more external resources. It is recognized that the visitor satisfaction begins from a minor thing, and a small difference determines a great satisfaction, and thus the software approach rather than hardware one is in need.

The study is based on an urban park design that is designed in consideration of the characteristics of Uijeongbu City, applied with adequate functions for the environment and showcasing the unique scenery in relation to the relocation of the US Air Force Camp Falling Water. The bases of the design are: the reasonable convergence of the square and park in consideration of the site characteristics; the application of an urban context as the park is located near a station; and the realization of an eco-friendly space. This study is based on foundation research regarding a review of urban square patterns, particular items in planning in relation to modern urban parks and the adaptability of the park in the future. Regarding space usage, the design is applied with notable ideas that allow the space to make its own characteristics through voluntary user activity in conjunction with the environment that will allow the park to cope with changes in the future, as opposed to a space that users experience through pre-determined programs. Below are the focal points of the design. First, the park is designed as an empty space which may accommodate the urban structural context of and usage patterns for being a field of the city ecology that changes and develops, beyond a passively-created square pattern. Such open spaces have a continuity which allows it to adapt to the development of the city. In addition, the design facilitates spontaneous processes through changes in usage pattern and time. Second, the design includes the message that the park and the city, natural things and artificial things, must communicate and network with each other. Hence the park shall not be an isolated green island within the city, but is an open space accommodating the demands for open area from nearby commercial, public and residential facilities; the park shall include a field that can accommodate a variety of programs. Third, the park is designed to encourage the effect of direct and indirect practical education by reflecting a physical plan as well as interesting experience design methods to lower carbon emissions and to create and maintain an eco-friendly space, the basis of a zero-emissions city.

Euglenoids occurring in freshwaters are indicator organisms to be used for assessing water quality and applying to environmental education. One hundred sixty eight taxa of euglenoids belonging to three orders, four families and nine genera occur in various waters, especially in eutrophicated and polluted places in Korea. Members of Euglena and Strombomonas are abundant in urban drainages and old ponds, and those of Trachelomonas, Phacus, and Lepocinclis often occur in stagnant waters such as natural wetlands and old swamps. Population size of some euglenoids is significantly correlated to nitrogenous nutrients. Euglena caudata, E. doses, E. ehrenbergii, E. haemichromata, E. geniculata, E. viridis, Lepocinclis ovum, Strombomonas urceolata, Phacus trypanon, Trachelomonas hispida, and T volvocina cells in Korea bloomed in winter and spring, when other phytoplanktonic algae greatly decrease. Blooming of euglenoids indicates tolerance to pollutants and positive selection as a result of competition with other phytoplankton species. We developed a web site on green euglenoids (Yahoo. com: Science/ Biology/ Botany/ Phycology/ Biology of Green Euglenoids), which may be use d for cyber education of water environment. We also presented a method for assessing water quality using diversity and population size of euglenoids, which is considered to be suitable for environmental education of polluted waters.

Background: Studies of morphological variation within and among populations provide an opportunity to understand local adaptation and potential patterns of gene flow. To study the evolutionary divergence patterns of Schlegel's Japanese gecko (Gekko japonicus) across its distribution, we analyzed data for 15 morphological characters of 324 individuals across 11 populations (2 in China, 4 in Japan, and 5 in Korea). Results: Among-population morphological variation was smaller than within-population variation, which was primarily explained by variation in axilla-groin length, number of infralabials, number of scansors on toe IV, and head-related variables such as head height and width. The population discrimination power was 32.4% and in cluster analysis, populations from the three countries tended to intermix in two major groups. Conclusion: Our results indicate that morphological differentiation among the studied populations is scarce, suggesting short history for some populations after their establishment, frequent migration of individuals among the populations, and/or local morphological differentiation in similar urban habitats. Nevertheless, we detected interesting phenetic patterns that may predict consistent linkage of particular populations that are independent of national borders. Additional sampling across the range and inclusion of genetic data could give further clue for the historical relationship among Chinese, Japanese, and Korean populations of G. japonicus.

A MOM-based algorithm (MOMA) has been developed for moving force identification from dynamic responses of bridge in the companion paper. This paper further evaluates and investigates the properties of the developed MOMA by experiment in laboratory. A simply supported bridge model and a few vehicle models were designed and constructed in laboratory. A series of experiments have then been conducted for moving force identification. The bending moment and acceleration responses at several measurement stations of the bridge model are simultaneously measured when the model vehicle moves across the bridge deck at different speeds. In order to compare with the existing time domain method (TDM), the best method for moving force identification to date, a carefully comparative study scheme was planned and conducted, which includes considering the effect of a few main parameters, such as basis function terms, mode number involved in the identification calculation, measurement stations, executive CPU time, Nyquist fraction of digital filter, and two different solutions to the ill-posed system equation of moving force identification. It was observed that the MOMA has many good properties same as the TDM, but its CPU execution time is just less than one tenth of the TDM, which indicates an achievement in which the MOMA can be used directly for real-time analysis of moving force identification in field.
