This study explored to what extent Korean science teachers perceived socioscientific issues (SSI) as an effective instructional tool for creativity and character (CreActer) education; which was recently announced as a main goal for the Korean National Science Curriculum 2009. The guiding research questions were as follows. (1)How do science teachers conceptualize the relationship between creativity and character in the context of science classes? (2) What do science teachers think about the possibility of CreActer education through SSI in science classrooms? Thirty science teachers participated in individual interviews (each lasted 20-90 minutes). In the results, the teachers' perceptions on CreActer education and SSI for CreActer education were categorized into four profiles. Eleven teachers in Profile A thought that creativity was positively correlated with character education because their understanding of creativity and character embraced a very broad range of elements. They mentioned that addressing SSI in the science classes would be satisfactory to cover those elements of CreActer education. Six teachers in Profile B mentioned similar elements of creativity and character of Profile A, but reported that, in their experience, creativity was often inversely correlated with character. However, they responded that addressing SSI would be a good way to integrate creativity and character in the science classes. Ten teachers in Profile C believed there was no relationship between creativity and character, but took a positive stance on CreActer education through SSI. Unlike Profile A and Profile B, they tended to regard character as only an interpersonal virtue. And three teachers in Profile D had a narrow perspective on CreActer education. Not only did they think creativity had no relationship with character, but also disagreed that CreActer education would be activated by addressing SSI in science classrooms. The results imply that SSI could be used as an effective instructional tool for CreActer education, but this can be possible when science teachers expand their view on CreActer education.

Light plays an important role in making a continuity of space and in determining the distinctive expression and char-acter of a space. Particularly, the introduction of natural light derives from our esthetic needs, as well as from the fundamental biologi-cal necessities of human beings. And also, adaptation to time and space is the vital factor of human survival and prosperity. Our visual recognition of light is usually formed not only by practical illumination but by analogy, expection and expe-rienced of lighting itself. As the forecase of natural light is (almost) impossible be-cause of variables such as changing weather, reflection rate of light and the patterns of shade, in designing the introduc-tion of daylight, there should be follow-ed careful considera-tion of the adaptation to such variety and the impet-us of light. The research was conducted to mane a contribution to cre-ate more rich and beautiful interior spaces by studying the characteristic of light which is one of the important factors of interior space design, and by inquiring the way to intro-duce light and its effect through the practical examples of Alvar Aalto, Le Corbusier and Louis I. Kahn.

To examine the relationship between the casual infection of gastric cancer and lifestyle and nutritional status we surveyed 169 persons 90 females and 79 males aged 40∼69 years from June 7 to June 14 1997 in Whachon area Kang-Won Do Korea. For this purpose we investigated Helicobacter pylori infec-tion and identified the effect of sex age, smoking alcohol consumption economic status occupation life-style and food intake on Helicobacter phlori infection. Helicobacter pylori status was evaluated using an en-zyme-linked immunosorbant assay(ELISA) for anti-Helicobacter pylori immunoglobulin G(IgG). Helicob-acter pylori infection was present in 66.3% of total subjects namely 67.7% of female and 64.4% of male and its prevalence increased with smoking low education level and low monthly income. Energy total protein calcium and vitamin C intakes in the negative Helicobacgter phlori infection group were higher than those in positive Helicobacter pylori infection group. However iron and niacin intakes were lower in the helicobacter pylori negative group than in the positive group.

The aim of the present study is to research into the household work time change and its structure in urban home makers by the choosen eleven studies and KBS's Data 1981, 1983, 1985, 1987. This study were proceeded under some limitations, it is choosen eleven studies that is different region: large city, medium and small town, and the household work's categories of original auther were changed. And KBS's Data was composed of general formation without personal character of home maker: FLC, number of childeren, family type, education, region. Although this study have a certain meaning of implementation, research into the household work time change and its's structure. The major findings of this study can be autlined as follows: (1) Total household work time did'nt so much changed through the choosen eleven studies compared with the last twenty years ago. In the change of each province household work time, time connected with meals and dwelling did not showed consistancy of change. But cloth laundering and mending time of 80's were declined compared with 70's. Family care time of 80's was increased, home management and buying time was declined untill '85, but again increasing trend '87. In choosen eleven studies, the household work time structure of urban home makers can be outlined: time connected with Meals>Family care>Cloth laundering and mending>Dwelling>Home management and Buying. (2) KBS's time-series data were analized as follows: a) Total household work time of '87 was declining gradually in weekday (34 minutes), sat. (41 minutes), sun (1 house and 2 minutes) compared with '81. b) The change of each province household work time: the time of cooking and sewing home management were declining gradually in its Mean time and its ratio of acters. The acter ratio of household worker in '81, '83, '85 was composed Cooking > Cleaning > Laundering > Home management > Buying > Child care > Sewing. In '87 was composed Cooking > Cleaning > Laundering > Buying > Home management > Child care > Sewing. c) The structure of household work time revealed some differences in each year and a day of the week.

In this study, a chitosan based coating method was developed and applied on the shoe lining leather surface for evaluating its inhibition to bacterial and fungal attacks. At first, chitosan was prepared from raw prawn shells and then the prepared chitosan solution was applied onto the leather surface. Secondly, the characterization of the prepared chitosan and chitosan treated leather was performed by solubility test, ATR-FTIR, XRD pattern, SEM and TGA. Evaluation of antimicrobial efficacy of chitosan was assessed against two gram positive, two gram negative bacteria and a reputed fungi by agar diffusion test. The results of this study demonstrated that chitosan took place in both the surface of collagen fibres and inside the collagen matrix of crust leather. The chitosan showed strong antimicrobial activities against all the tested microorganisms and the inhibition increased with increasing percentage of chitosan. Therefore, the prepared chitosan in this study can be an environment friendly biocide, which functions simultaneously against different spoilage bacteria and fungi on the finished leather surface. Thus by using the prepared chitosan in shoe lining leather, the possibility of microbial attack during shoe wearing can be minimized which is one of the important hygienic requirements of footwear.

UCS (=ISO/IEC 10646, =Unicode) will be used widely as globalization. If UCS is used for official purpose in Koreas, UCS solves a Problem in different hangeul code between South and North Korea. But, UCS is not a solution for problems in unequal order with the same character. IS0/1EC 146sl : 2000 (International String Ordering), which is a international standard for string ordering, defines a framework sorting all char-acter strings consisting multi-national scripts. Because the Common Template Table in ISO/IEC 14651 defines orders of characters, we can change orders of characters without changes of characters sequences in programs. Therefore, we can solve a ordering problem without unifying order of hangeul in South and North Korea. Functions related ISO/IEC 14651 are contained by system librarys in unix-based operating system such as Linux, Solaris and FreeBSD. We implement EUC-KR-based North Korean locale, which includes North Korean hangeul order, in Linux in order to use North Korean locale in South Korea. And we develop a program ordering strings with South and North Korean hangout order.

This paper presents a study on the radiation characteristics of low-VHF band electrically small antenna for direction finding. Firstly, it is simulated the antenna for mounting on flat ground and tank model(in 40MHz), and measured for mounting 1/10 scaled model(in 400 MHz). In case of flat ground feed at ${\phi}=0^{\circ}$, $180^{\circ}$(xz-plane), yz-plane $E_{\phi}$ (H-plane) and xz-plane $E_{\theta}$ (E-plane) radiation patterns are hemispheric omni-direction due to effect of narrow ground side. Then, in case of tank model, it is shown equally in case of the flat ground, yz-plane $E_{\phi}$ (H-plane) and xz-plane $E_{\theta}$ (E-plane) radiation patterns are hemispheric omni-direction nearly without effect of mounting position. Therefore, the suggested electrically small antenna for direction finding, in case of mounting on ground narrow side xz-plane(E-plane), is shown more stable radiation patterns as direction finding antenna.

This study started with curiosity about theatre without its three elements and would reveal its possibility through performance and experiment and promote the expansion of each element and the development of a new form at the same time. After the occurrence of COVID-19, theatre has come up against a big limitation of contact-free, untact communication due to its inherent characteristic of 'presence.' For the survival of theatre in the rapidly changing world, it is desperately necessary to check the existing performance method and to be concerned about its development for the future. Thus, this researcher started from a more fundamental exploration of theatre focused on an "experiment of theatre without its three elements" and would sort out the three elements (actors, audience, and a play) from a macroscopic perspective. Also, the researcher would investigate the impacts of these elements on the performance and the possibility of theatre even after removing the elements through performance and experiment. This study consists of one performance and two experiments and is based on the interviews and progress details conducted by the planner and experimenter and the survey with the experiment participants. The significance of this study is its reflection on the essence of the genre, theatre, and the roles of all elements constituting that, not from a narrow perspective that would simply define the concepts of the elements but through the expansion and change of them. Furthermore, hopefully, it will be connected to the discovery of a new theatrical format that has not been considered through its combination with another genre.
