The purpose of this study was to find out how to operate Technology Home Economics in the 2009 revised national curriculum and Home Economics teachers perception on the current states in the middle schools, focused on intensive course-taking, block-time, and total hours to take the course. Data were collected from the 118 Home Economics teachers nationwide through e-mail from May 25 to June 4, 2011, and analyzed with frequencies, percentage, means, t-test, cross-tabulations, and ANOVA. The results showed that Technology Home Economics was intensively taken in the most of all schools(91.5%) during 4 semesters by senior and freshmen or junior. Teachers were relatively less involved in the decision making process for intensive course-taking than did the school managers and dissatisfied with the fact of intensive course-taking. But a few school adopted block-time and most teachers did not think it was necessary. Over half of schools offered the same 16 hours of Technology Home Economics as in the previous 2007 revised curriculum, but nearly 2 out of 5 schools reduced the hours from 1 to 8 with an average of 2.8 hours. To keep the necessary hours to teach the full contents of Technology Home Economics should be protected. The follow-up research needs to be conducted to investigate the changes in the perception of Home Economics teachers.

The Practice of Landscape Urbanism has been criticized on two aspects; Landscape Urbanism does not yet provide differentiated forms of planning and design neither able to fill the gap between theory and practice. In response to these criticisms, Landscape Urbanists have tried to provide additional cases that can exemplify achievements of Landscape Urbanism in practice. There has been another type of effort to suggest distinct planning and design strategies of Landscape Urbanism from theoretical texts. However, these approaches overlooked the fact that professional practice actually gave huge influence on the theoretical framework of Landscape Urbanism. Based on this observation, the study examined the development process of Landscape Urbanism by verifying the correlation between its practice and theory. Through an extensive literature review, the study suggested horizontality, infrastructure, process, ecology, media, hybrid, site, and scale as eight major concepts of Landscape Urbanism. Afterwards, the study classified 51 projects cited in major essays and articles of Landscape Urbanism into four categories: Archetypal projects, precedent projects, exemplary projects, and progressive projects. The correlation between strategies of the selected projects and main theoretical concepts was analyzed. The study found out that the early stage of the theory was focused on defining and explaining the new design and planning approaches of contemporary design projects related with landscape. However, these days, Landscape Urbanism became a more productive in providing diverse types of practice sharing the direction and vision proposed by the theory. Various projects influenced in constructing theoretical structure of Landscape Urbanism as well as proved that the suggestions of Landscape Urbanism could be effective to reorganize contemporary cites in the form of design and planning strategies. The observation of this study can contribute to provide proper answers to the criticism on practice of Landscape Urbanism and be helpful in understanding the limits and unrealized potentials of Landscape Urbanism as a practical theory.

As multimedia information recently increases fast, various types of retrieval of multimedia data are becoming issues of great importance. For the efficient multimedia data processing, semantics based retrieval techniques are required that can extract the meaning contents of multimedia data. Existing retrieval methods of multimedia data are annotation-based retrieval, feature-based retrieval and annotation and feature integration based retrieval. These systems take annotator a lot of efforts and time and we should perform complicated calculation for feature extraction. In addition. created data have shortcomings that we should go through static search that do not change. Also, user-friendly and semantic searching techniques are not supported. This paper proposes to develop S-MARS(Semantic Metadata-based Multimedia Annotation and Retrieval System) which can represent and extract multimedia data efficiently using MPEG-7. The system provides a graphical user interface for annotating, searching, and browsing multimedia data. It is implemented on the basis of the semantic metadata model to represent multimedia information. The semantic metadata about multimedia data is organized on the basis of multimedia description schema using XML schema that basically comply with the MPEG-7 standard. In conclusion. the proposed scheme can be easily implemented on any multimedia platforms supporting XML technology. It can be utilized to enable efficient semantic metadata sharing between systems, and it will contribute to improving the retrieval correctness and the user's satisfaction on embedding based multimedia retrieval algorithm method.

This research analyzed the spatial components and establishment of the Tap-gol Park according to the plans between 1897 to 1916 when the discussions on the construction of the park began and it was accomplished as an urban park. The results are as follows. The establishment of Tap-gol Park can be divided by three period. Firstly, Tap-gol Park was owned by the royal family from 1987 to 1904. The discussions on construction of Tap-gol Park as a first urban park of Gyeongseong(京城) in 1897, and the private houses were tear down in order to secure land for the park in 1899. Gates and fences surrounding of Tap-gol Park were organized and it was opened in 1902 based on park plane of turtle - shaped. The octagonal pavilion for 'Lee-Wang-Jik musical band(李王職音樂隊)' was relocated in the southwestern part of the park in 1903. Secondly, Tap-gol Park was used actively by the public between 1910 to 1913, because it was opened for individuals. Also The boundary of Park were changed by surrounding facilities and recreational facilities and benefits was complemented for users. Tap-gol park was opened at nighttime in August 1913. Tap-gol Park was used as a place of amusement park. Thirdly, commercial facilities were made as the park facility between 1914 to 1916. The purpose of 'Kkikdajeom(喫茶店)' was similar to the one of modern cafes. It was built as a typical Japanese tea-house with a small pond having an island and a bridge constructed inside. With the increase of usage of Tap-gol Park as a recreational area by the citizens in 1916, the pavilion as a rest area and toilet as amenities were supplemented. Superintendent's office was equipped too. Simple chairs made from the wooden logs were installed around greenhouse, concert hall, the Wongaksa Buddhist temple(圓覺寺址十層石塔), and the flower garden was fenced round. After the relocation of Yongsan music band to Tap-gol Park, the existing concert hall was demolished. The shape of the park which was seen from the pictures of the magazines of 1920s were achieved as early as 1916. The importance of this research includes the basis to revise the errors of the preexistence researches and value of historical material of the design plan reference of the park which was accomplished during the Japanese colonial era. Also this research is to study on the spatial components of the modern landscape architecture and parks.

For the purpose to verify the physico­chemical properties of Korean waxy wheat, comparative analyses between waxy wheat lines and their respective maternal parents were performed on mixing and pasting properties, and flour particle sizes. The particle sizes of waxy wheat flour were significantly larger than those of their parents when milled in a same condition. Although the protein contents of flour in waxy wheat lines tested were high as much as those of bread wheat, the quality parameters showed lower baking uses based on sedimentation volumes and mixing characteristics. Waxy flour required more water than non-waxy flour to obtain the proper mixogram. Waxy wheat flour showed more or less higher onset pasting temperatures and much higher breakdown viscosities than their respective parent flour in the Rapid Viscograph test. Moreover, peak viscosity temperatures and final viscosities were dramatically reduced in waxy wheat lines by showing $79.4 - 81.7^{\circ}C$ and 101 ­116.9 RVU, respectively, compared to their parents in that the temperatures above $95^{\circ}C$ and the viscosity ranges of 148 -171.8 RVU.

This paper has attempted to reexamine current international circumstance and the meaning of regionality and discover the practical design strategy in the process of observing the trend of contemporary landscape architecture from the perspective of regionality. Contemporary landscape architecture has started to discover possibility in the local value and create identity. This tendency can be classified as follows: First, regionality is re-examined as a medium which can integrate nature, culture and city. As a concept which contains time and spatial continuity, landscape is a matter of the identity of land and area. Second, regionality has been reinterpreted and recreated by designers. Landscape designers attempt to restore the past memories and traces instead of adding a new concept after erasing previous physical features. This design attitude has spatialized time continuity. Third, site is seen as a palimpsest, not tabula rasa in contemporary landscape architecture. It has been attempted to visually materialize the natural and ecological processes and spatial features. Fourth, site is approached in a tectonic approach instead of analytical approach. It is attempted to organize and restore the geological and archeological memories and ecological processes. Differentiation has emerged as a critical design strategy in contemporary landscape architecture. However, regionality is also formed through an interaction with continuity as well as through differentiation. In this sense, the following possibilities can be reviewed as practical design strategies to realize regionality: First, a terra-tectonic approach discovers and selects possibility in the site and expresses the site, creating practical possibility which strengthens regionality. If the memory and conditions of the site are different, the identity would different as well. Second, continuity of region itself is a gene pool with comparative advantage. As a rough sketch of design, it acts as a loose conformity on designers' experience and practice. Of course, this approach is not absolute with some limitations. It is necessary to explore practical strategies.

This paper aims at examining the regional difference of changes in the business organization of retailing in the Seoul metropolitan areas, as an attempt to understand regional structure of retailing within metropolitan areas showing the trend of suburbanization. On the national level, retail sales have concentrated on the large metropolitan areas, especially on the Seoul metropolitan area, with the concentration of population and income. Within metropolitan areas, the suburbanization of retailing has made the larger structure of retail and multi-store retail appeared. In order to confirm such phenomenon, this paper is to analyze and to compare the industrial composition of retailing using industry data of 1979 and 1991. And this paper is to analyze the regional changes in the characteristics of business organization of retailing, with the index including the percentages of establishments with less than under four employees, juridical establishments, employees of ordinary times, and the annual sales per establishment of detailing. The characteristics of business organization of retailing in analyzed by principal components analysis, and the types with component in each district (city, county, ward) is analyzed by cluster analysis(Ward method). The data of 1979 were obtained from the statistics in the Census of Wholesale and Retail Trade published by the National Bureau of Statistics of Economic Planning Board, and that of 1991 were obtained from the statistics in the Report on Establishment Census (Vol.3 Wholesale and Retail Trade) published by the National Statistics Office. The following are resultant findings. 1. In Seoul metropolitan area, changes in the industrial composition of retailing with annual sales from, 1979 to 1991 show very higher composition rates of 'general merchandise stores' and 'retailing of personal transport equipment and gasoline service stations', but comparatively lower composition rates of 'retailing of food, beverages and tobacco', 'retailing of textiles, clothing, footwear and apparel accessaries', 'general retail trade, n.e.c.',and 'retailing of household fuel'. 2. The characteristics of business organization of retailing in Seoul metropolitan area presents the prevailence of small, personal business organization and especially larger employees of ordinary times. 3. Business components of retailing by principal components analysis in Seoul metropolitan area are follows: 1 All retaining industries are larger business scale. 2. Larger business take the 'retailing of taxtiles, clothing, footwear and apparel accessories', 'retailing of furniture, home furnishing and equipment', and 'retailing of jewellery and watches' is main characteristic legal organization and employees of ordinary times. 4. Types changes in business organization of retailing in Seoul metropolitan area represent legal organization and employees of ordinary times taking the 'retailing of textiles, clothing, footwear and apparel accessories', 'retailing of furniture, home furnishing and equipment',and 'retailing of jewellery and equipment', and 'retailing of jewellery and watches', and legal organization taking 'general retail trade, n.e.c.' in 1979. All retailing industries are changed into larger business scale, in 1991. These phenomena of business changes appeared southeastern regions in Kyunggi-do(province). And larger business scale taking the 'retailing of textiles, clothing, footwear and apparel accessories', 'retailing of jewellery and watches', and 'general retail trade, n.e.c.; are appeared in the legal organization in 1979. 'Retailing of personal transport equipment and gasoline service stations' are appeared in employees of ordinary times in 1991. These phenomena of business changes in appeared in eastern and northern regions in Kyunggi-do. 5. Changes in the business organization of retailing in Seoul metropolitan area is appeared in legal organization and employees of ordinary times for some industries in 1979, larger business scale of retailing and employees of ordinary times in 'retailing of personal transport equipment and gasoline service stations' are the characteristics in 1991.

Landscape around a settlement is not only a natural object, but also a matters of the man in the co-relation with his environment. Man perceives the landscape rational or sensible. Then it changes into the substance for him and influences him: as we see often in the folklore, that is of importance in the mind. Man reacts against his surroundings deceidedly, selfassurd or commonly, and uses sometimes the landscape to the elements for realization, physical or symbolical. Out of one character of korean villages, adaption to the circumstances, we can notice also its inner image, the reflection of the mind. Seeing and perceiving the environment emotional or reasonable and, reflecting and descreibing the inner self on the space. Here, the landscape and the nature are matter of the man, a scale for his ethical estimation or a mailer of the realization his mind. It is difficult, but important, such a immanent picture in(or of) the landscape to find. This is a preliminary study in such a way.

One of the main interests in relation to heavily contaminated gully-pot sediment in urban area is the short term mobility of heavy metals, which depends on the pH of acidic rainwater and on the buffering effects of carbonate minerals. The buffering effects of carbonates are determined by titration (acid addition). Leaching experiments are carried out in solutions with variable initial HN03 contents for 24h. The gully-pot sediment appears to be predominantly buffered by calcite and dolomite. In case of sediment samples, which highly contain carbonates, pH decreases more slowly with increasing acidity. On the other hand, for the sediment samples, which less contain carbonate minerals, pH rapidly drops until it reaches about 2 then it decreases slowly. The leaching reactions are delayed until more acid is added to compensate for the buffering effects of carbonates. The Zn, Cu, Pb and Mn concentrations of leachate rapidly increase with decreased pH, while Cd, Co, Ni, Cr and Fe dissolutions are very slow and limited. The solubility of heavy metals depends not only on thc pH values of leachatc but also on the speciation in which metals are associated with sediment particles. In slightly to moderately acid conditions, Zn, Cd, Co, Ni and Cu dissolutions become increasingly important. As deduced from leaching runs, the relative mobility of heavy metals at pH of 5 is found to be: Zn > Cd > Co > Ni > Cu » Pb > Cr, suggesting that moderately acid rainwater leach Zn, Cd, Co, Ni and Cu from thc contaminated gully-pot sediment, while Pb and Cr would remain fixed. The buffering effects of Ca- and Mg-carbonates play an important role in delaying as well as limiting the leaching reactions of heavy metals from highly contaminated gully-pot sediment. The extent of such a secondary environmental pollution will thus depends on how well the metals in sediment can be leached by somewhat acidic rain water. Changes in the physicochemical environments may result in the severe environmental pollution of heavy metals. These results are to be taken into account in the management of contaminated sediments during rainstorms.

The Korean Ministry of Culture, Sports and Tourism has held "Travel Week" since 2014 to encourage the people to take a vacation and disperse the seasonal tourism demand that is concentrated in summer in Korea. As part of the program, the Korea National Park Service has also operated the participatory lowland exploration program that offers nature-themed attractions and enjoyment in national parks across the country during the "Travel Week" since 2018. The purpose of this study was to investigate the satisfaction with the program and intention to participate again of participants in the "National Park Spring Week Program" which is held in national parks during the "Travel Week." We conducted a self-report survey of 1,281 participants in the "2019 National Park Spring Week Program" held in 18 national parks across the country. The analysis of responses on the difference in the participants' satisfaction and intention to participate again according to the awareness in advance of the "2019 National Park Spring Week Program" showed that the average satisfaction and intentional to participate again of those who were aware of the program before visiting national parks were statistically significantly higher than those who were not. As for the type of national parks, those who participated in "maritime and coastal national parks" and "historical national parks" showed the statistically significantly higher satisfaction and intention to participate again than those who participated in "urban national parks." As for the type of the programs, those who participated in "cultural performance" and "exploration experience" showed the statistically significantly higher satisfaction than those who participated in "exhibition," "PR booth," and "campaign." Those who participated in "cultural performance" and "exploration experience" showed the statistically significantly higher intention to participate again than those who participated in "exhibition" and "PR booth." This study is expected to provide basic data for establishing a policy to improve exploration services in response to the increasing number of visitors to national parks in spring and fall as well as the peak season of summer.
