The aim of this study is to explore the school adaptation and aggression of the children selected from 3 different SES communities and to investigate how parenting styles and children' school adaptation and aggression are different according to community-level socio-economic status. Subjects were 441 elementary school graders(229 boys and 212 girls, from the 4th graders to the 6th graders. Community SES was measured by the proportion of adult population holding a bachelor's degree or higher among the whole adults aged more than 30 and divided into 3 regions(rated high, middle and low in the metropolitan city). Data analysis was by F-test and multiple regression. The children from the high and middle SES community were more adaptive to school and less aggressive than those from the lower SES community. And the parents(or caregivers) from the high and middle SES community were more authoritative than those from other regions. These findings tell us that the children from the lower SES community are at risk and that some special programs to support children and their parents are needed.

This study was conducted to evaluate effects of somatic embryos (SEs) induction with different kinds and concentrations of osmoticum, with gelrite and SEs germination with different abscisic acid (ABA) and embryogenic tissue lines (ETLs) in Japanese red pine (Pinus densiflora). In comparison of somatic embryos induction with different kinds and concentrations of osmoticum, the highest record (45/90 mg FW) was obtained from the treatment of 0.1 M maltose+3.75% PEG 4000. In addition, the higher one was also recorded from 0.2 M maltose (41 SEs), it turned out this treatment was also effective in induction of SEs with previous one. In effects of various gelrite concentrations for SEs production, no SEs were occurred in the treatment of 0.4 or 0.6% gelrite, however, the highest no. of SEs shown in 1.0% gellrite (41 SEs), and some comparable results were also marked with 0.8 (37.3 SEs) or 1.2% (39.7 SEs) gelrite. Therefore, SEs can be produced from above 0.8% concentration of gelrite. Finally, in comparison of SEs germination with different concentrations of ABA, ETLs, and AC, the best germination rates (45%) were obtained from the SEs derived from both concentrations of 150 and $200{\mu}M$ ABA in 06-6 ETL and when cultured on germination supplemented with 0.2% AC. When SEs were cultured on germination medium without AC, best germination rate (28.9%) came from the SEs which cultured on $250{\mu}M$ ABA in 06-6 ETL.

Objectives. Few studies have attempted to explain the association between socioeconomic status (SES) and obesity in Korea Especially the studies on same race with different SES at same time are good for SES influence estimation. The present study highlights the influence of SES of parents on adolescent obesity. The subjects are the same race, but live in different areas, with different SES, Seoul and Yangpung in Korea, and Yanbian in China. Methods. The cross-sectional study was conducted in Mar-Jun 1996. We carried out anthropometry, 24 hour-recall diet survey, self-reported questionnaire about sociodemographic characteristics and physical activity. For SES indicators, we used income and education of parents. Results. The relationship between SES of parents, defined as educational status, and obesity in boys in Korea and China is direct, but not significant. The relationship is inverse and nonsignificant among Korean girls, However, for the Korean girls in severe obesity, the relationship is significant. For the Korean-Chinese girls, there is an inverse relationship between the education level and obesity but a direct relationship between the income level of parents and obesity. For the Korean adolescent, there are a direct association between the SES of parents and the nutrients factors such as energy, protein, and fat intake. The energy expenditure of adolescent has no relationship with SES of parents. Conclusion. Among boys, the higher the SES, the greater the risk of obese. Among girls in Korea and Korean-Chinese, on the other hand, the lower the educational status of parents, the greater the risk of obese.

System Entity Structure/Model Base (SES/MB) enhances organizing model families and storing and reusing model components in the multifaceted system modeling. However, the real world can be described not only an individual system but also a collection of those systems, which is called system of systems (SoS). Because SES/MB has a limitation to simulate the SoS using HLA/RTI, an extended framework is required to simulate it. Therefore, this paper proposes System of Systems Entity Structure/Federate Base (SoSES/FB) for simulation in a distributed environment (HLA/RTI). The proposed method provides the library of federates (FB) and System of System Entity Structure (SoSES) formalism, which represents structural knowledge of a collection of simulators. It also provides a methodology for the development process of distributed simulation. The paper introduces the anti-missile defense simulation using the proposed SoSES/FB.

The model of a FMS (Flexible Manufacturing System) admits to a natural hierarchical decomposition of highly decoupled units with similar structure and control. The FMS fractal architecture model represents a hierarchical structure built from elements of a single basic design. A SES (System Entity Structure) is a structural knowledge representation scheme that contains knowledge of decomposition, taxonomy, and coupling relationships of a system necessary to direct model synthesis. A substructure of a SES is extracted for use as the skeleton for a model. This substructure is called pruned SES and the extraction operation of a pruned SES from a SES is called pruning (or pruning operation). This paper presents a pruning operation called recursive pruning. It is applied to SES for generating a model structure whose sub-structure contains copies if itself as in FMS fractal architecture. Another pruning operation called delay pruning is also presented. Combined with recursive pruning the delay pruningis a useful tool for representing and constructing complex systems.

A curriculum is a measure of how high level of knowledge is educated to students affiliated to university institutions, and is used as an indicator evaluating usefulness of the university institutions. For this reason, Designing and assessing curricula is a critical to high education institutions. However, in the case of development and quality assessment of a curriculum with a traditional way, finding a right curriculum which a designer intends is a time consuming and error-prone process. Therefore, in order to improve these problems, we propose the curriculum design engine using SES (System Entity Structure) / DEVS (Discrete Event System Specification) Framework in this paper. The SES describes all possible combination of curricula for students. The DEVS framework provides a simulation environment for models created from the SES by the students. The proposed engine will show appropriate curricula for students after a simulator appropriately filters students' requirement, according to conditions.

A point based speed enforcement system(SES) has been widely used in roadways to reduce the operating speeds and potential traffic accidents. Recently, the needs for introudcing new SES using point-to-point speed measurement was presented, however, no practical guidelines or justification of the system was available. This study investigated the effectiveness of the current SES and introduction of the new SES through user interview survey method. Survey results showed that 33% of respondents were unsatisfactory to the current way of SES operation, which was 11% higher than satisfactory respondents, and about 70% of the respondents supported the introduction of point-to-point based SES operation. A majority of respondents preferred the straight roadway segment, bridge and tunnel, and curved roadway segment for a start application site with the segment length of 1-5 km long. Using these survey results, an introduction scheme was discussed in terms of legal bases, installation criteria, and operational guidelines.

Objectives: To analyze the relationships of socioeconomic status(SES) to health status and health behaviors in the elderly. Methods: Data were obtained from self-administered questionnaire of 4,587 persons, older than 65 years, living in a community. We measured the sociodemographic characteristics, socioeconomic status, health status (subjective health status, acute disease, admission experience, dental state, chronic disease etc.), activities of daily living (ADL), instrumental activities of daily living (IADL), and mini-mental state examination-Korean (MMSEK). Binary and multinominal logistic regression analyses were employed to analyze factors affecting on the socioeconomic status of the elderly. Results: With regard to the SES and health status, those with a low SES had poorer subjective health states and lower satisfaction about their physical health. Also, acute disease experiences, admission rates and tooth deciduation rates were higher in those of low SES. In the view of physical and cognitive functions, the ADL, IADL and MMSE-K scores were also lower in those of low SES. However, with regard to health behaviors, lower smoking and alcohol drinking rates were found in the low SES group, and a similar trend was shown with regular physical exercise, eating breakfast, and regular physical health check-up. From these findings, we surmise that those with low SES have a poorer health condition and less money to spend on health, therefore, they can not smoke or drink alcohol, exercise and or have a physical health check-up. Conclusion: This study suggests that socioeconomic status plays an important role in health behaviors and status of the elderly. Low socioeconomic status bring about unhealthy behavior and poor health status in the elderly. Therefore, more specific target oriented(esp. low SES persons) health promotion activities for the elderly are very important to improve not only their health status, but their health inequity also.

Saint-Denys Garneau, auteur québécois, écrit ses poèmes et peint ses tableaux à partir de ses poèmes. La création de ses oeuvres poétiques et picturales lui est très utile pour se relever de son désespoir dû à sa maladie cardiaque. Pour Garneau, il est important de rechercher le moi. Il veut alors garder l'équilibre entre le désespoir causé par sa maladie et l'espoir de ses activités créatrices, et entre le moi incertain et le moi ineffaçable. Les désirs de ce poète-peintre pénètrent ses oeuvres poétiques et picturales qui représentent les paysages de la campagne québécoise (Sainte-Catherine-de-la-Jacques-Cartier) où il a habité. Les paysages de campagne reflètent le temps passé et le temps présent de Garneau dans ses poèmes et ses tableaux. Il a passé son enfance heureuse, parce que son état de santé ne s'aggravait pas et qu'il était beaucoup aimé de sa mère. Il accepte donc dans sa conscience sereine les paysages déroulants devant lui, en représentant son enfance à travers son esprit ouvert vers le monde. En revanche, il refuse les paysages étendus devant lui en se trouvant dans une situation mélancolique à cause de la progression de sa maladie. Sa conscience révoltée contre sa maladie se fonde sur son inconscient. Son inquiétude sur l'incertitude de son futur lui permet de refuser les paysages et le temps présent(où il souffre d'une maladie cardiaque). Le rythme irrégulier de la langue poétique et la touche inharmonieuse mise sur la toile représentent les circonstances du refus. Les paysages de campagne évoquent également, dans ses oeuvres poétiques et picturales, d'une part, Garneau qui erre entre le monde visible à l'oeil nu et le monde invisible à l'oeil nu(mais visible à travers l'âme). Et d'autre part, les paysages montrent des traces surréalistes et géométriques, causées par l'irrégularité du rythme linguistique et l'abstraction de l'art contemporain.

Supplemental Educational Services (SES) are government initiated tutoring services to strengthen basic skills of academically underachieving students and thus close achievement gaps among students. Recently, however, the direction of SES has shifted its gear away from the test-driven accountability system in the United States (US) and Korea. Based on related literature, official documents, and statistics data, this study investigates major aspects of SES in the US and Korea, suggesting implications for future SES in the two countries. Major findings illustrate; 1) SES both in the US and Korea aim to serve students with underachievement yet place a primary emphasis on academics, 2) the US and Korea show contrasting results of SES in students' academic achievement, 3) the US and Korea use different approaches in selecting SES participants, which is closely related to equality in educational opportunities, 4) the major difference between the US and Korea is the openness of real markets for SES. Based on these findings, this study proposes practical implications for future SES in Korea and the US.
