  • The time management and allotments for various activities of daily life is much different by age groups. This study analyzes time allotments of different age groups for various activities of daily life to figure out the change of main activity by aging through 2009 time use survey by National Statistical Office. Especially we focus on time allotments of rural elderly population and intangible factors for life quality of people instead of physical and environmental elements. The results show that there is a large gap of time allotments for paid and unpaid working time of rural and urban elderly population. Whereas the time for leisure of elderly women in rural areas is much shorter than that of urban elderly women and rural elderly men spend more time to provide community services and help to other households. However, the percentage leisure time of rural elderly people for passive activities such as TV, radio, magazine etc. is longer than that of urban elderly people. We hope that our analysis data could be used for developing new policies and project to improve the life quality of rural elderly population.

  • Altered mRNA expression of two metallothionein isoforms (MT-IA and MT-IB) in response to acute heavy metal exposure was examined in mud loach, Misgurnus mizolepis, fry using a real-time RTPCR assay. Sublethal exposure (1 or 5 ${\mu}M$) to Cd, Cr, Fe, Mn, Ni, and Zn resulted in highly variable transcriptional responses of the two MT isoforms to the heavy metal ions, including upregulation, a steady state, and downregulation. Overall, the most potent inducer of both MT isoforms was Cd (up to 6-fold). Another exposure experiment using a series of doses of Cu revealed that the stimulation patterns of the two MT isoforms differed: MT-IA transcription was soon saturated at higher concentrations (about 2-fold at 1-4 ${\mu}M$ of Cu), whereas the activation of MT-IB was more dependent on the treatment dose (increased up to 5-fold at 3 ${\mu}M$). The isoform-specific allotment of constitutive and inducible functions was not as clear in fry as in adult tissues. Coordinated interaction between the MT-IA and MT-IB isoforms was hypothesized based on the finding that MT-IA represented a primary action under 'less stressful' or 'sublethal' conditions, whereas the activation of MT-IB became important under 'more stressful' or 'lethal' circumstances in this species.

  • The study aimed to assess the effectiveness of Korea-Israel science teachers inservice program. Thirty science teachers who participated in the inservice program responded to pre- and post tests of the survey instrument on (a) their perceptions to creativity fostering science education and understandings of current education status and reform movement, (b) degrees of changes about understanding of creativity and implementing teaching methods for fostering creativity before and after the program, and (c) their evaluative opinions on the program. Suggestions for improving the program were proposed as follows: First, a pre-service workshop for the program should be provided in order to clearly realize the essential purpose of the program through increase of participating teachers' understanding of facing conditions of education, school policy, reform movement toward science education fostering creativity. Second, for the content of the program, creativity is more emphasized. Appropriate content and sufficient time arrangement for creativity will develop teachers' conceptual understanding of creativity in depth. Third, classroom observation of exemplary science teaching for fostering creativity should be sufficiently arranged. Fourth, amount of content and time allotment to Israel culture, religion, and education system should be reduced.

  • First: The common points from "syllabus" period to that of "Course of study" are as follows: 1) with no introduction explained. the "Syllabus" or "Course of study" was made to be completed in accordance with the allotment of time (unit). 2) To teach how to rear animals and grow plants, and to make specimens with collected samples formed a great significant field of learning, which meant giving more emphasis on learning classification, life-centered education and basic field of learning than discipline-centered education. 3) The reason why the field of applied biology was emphasized on was that both periods had ideals in Common to educate persons more necessary and useful to the society than to major the pure academic field. 4) Both periods mainly dealt with problems of diseases, and physical health discussed all over the world in 1950's which accounts for necessity of the society to free from ignorance. Second; "The first curriculum period" and "the second one" are observed as follows: 1) The former took the unit (credit) system for the first time. It tried to lay down the conceptual hierarchy with "Biology I" and "II" divided, while "Biolgy I" is better systematized than "Biology II". 2) Discipline-centered education and structure fo knowledge are put more emphasis on especially in "the 2nd curriculum period". 3) And also in this period are included serious problems such as urgency of pollution, importance of nature conservation, population due to the development of industry. 'Third; With the recent curriculum laid down, experiments and teaching contents of subjects are put in harmony with each other and accordingly the process of Inquiry is laid emphasis on. Fourth; It is necessary to set up conceptual sequence and scope effectively in the curriculum.

  • The multi function radar is searching target and tracking through resource management at the same time. Increasing resource allotment of track, if more targets and faster the renewal rate of track, lead to decreasing quota of searching resource in limited resource. When the resource of search are decreased, it becomes degrade searching performance such as revisit time, number of detecting chance and tracking etc. Degraded performance of search reduces guided missile defense probability in complex strategy such as ship self defense. In this paper, we developed a modeling and simulation (M&S) tool that uses own-ship model, radar model, target model and defense model for analysis of self defense in complex strategy. We analyzed influence of ship self defense in complex strategy according to various target environments and track performance.

  • The current web implementation largely falls into process-oriented and object-oriented methods. Both ways implement the programs to be used for simple design of external outfit and auxiliary function of hybrid webs and it might lead to cost problems arising from waste of time and man-power to develop with it. Therefore, managed structural system programming which can be applied under .NET framework is suggested in a bid to solve these problems. The structural system design method under .NET environment by applying CS concept prefers to adopting the optimized design configuration suited to proper interfaces of UI configuration, which offers the environment to maintain the inheritance relationship by taking form of the balanced class allotment by domain, and continue to keep the connectivity between UX and UI which leads to application of interface of UX objects as form of objects through connection with objects in class design process. This development method enables programs to be implemented focused on representation methods of UI and UX, and helps relieve much of the burden on development costs.

  • The purpose of this study is to assist understanding the integrated subjects and to obtain implications required on the actual operation of curriculum by analyzing content elements and basic inquiry activities in the revised "wise lift" curriculum 2007. The result of this study is as follows. First, the formation of elements in contents of "wise life" deals with the passage of time based on changing seasons, myself and family in the 1st grade and the concept of space based on home and a village in the 2nd grade. Six main subjects and twelve activity subjects are presented per each grade. Second, number of activity subjects and content elements are reduced as compared with 7th curriculum so that the responsibility of operating classes based on activities is reduced and the purpose of rationalizing contents is somewhat fulfilled. Third, eliminating a relevant domains decisively when presenting the activity subjects assures the identification and purpose as the integrated subject focused on inquiry activities. Fourth, the result of analyzing the course-relevance on content elements shows that the allotment per each domain and course is less considered but the relevance of social studies is higher regardless of non-course characteristics as the integrated subject. Fifth, according to the component ratio of basic inquiry activities, 'Observing' and 'Debating' were presented as the most essential activities, and 'Measuring' and 'Making' were relatively low. By considering characteristics of course requiring balanced and various experiences of inquiry activities, additional discussions are required on appropriateness of the component ratio. Sixth, 'Observing' was increased and 'Debating' and 'Making' were decreased on the main activities in this revised curriculum as compared with 7th curriculum.
