The purpose of this study is to grope for some developmental strategies for traditional handicraft industry in Korean through focusing on its woodenware handicraft. Human beings built up the stone Age and also used the woodenware culture together with the stone culture. From the fact that there was a serious limit in preserving for the woodenware, the lacquered ware appeared. By dint of lacquering for a long time. The woodenware was used widely for an eating table during the Three Kingdom Period, the Koryo Period, and the Yi Dynasty. Since the 1960s it was declined as the cheaper stainless and plastics came in the market. But, for the woodenware handicraft as the traditional handicraft industry some developmental strategies in terms of governmental policies are needed.

'Saembon' was elementary mathematics textbook in the Period of Syllabus in Korea. First I classified Saembons in five groups. And then I regrouped them into two kinds. One kinds were published under U.S. Army Military Government, and other kinds were made under Republic of Koera. Two kinds of Saembon were very different in several aspects. I showed how they were different through real examples. Finally I tried to explain that Saembons under Republic of Koera were better than Saembons under U.S. Army Military Government.

In this study, middle and high school authorized mathematics textbooks which were used in the period of syllabus are traced. Since the first appearance of authorized textbooks in 1947, 11 types of authorized textbooks written by eleven teams of authors have been used in the period of syllabus. Among them, 5 types correspond to today's middle school textbooks, while 6 types correspond to a combination of today's middle and high school textbooks. Nor were all of them used until 1955. There were changes such as suspending publication, changing publishers, or cancelling authorization.

The authors did conservation treatment of wooden objects excavated from Isong Sanung Fortress upon request of the Museum of Hanyang University. The authors investigated types of the trees prior to conservation treatment to find out 1 Pinus spp. and 11 Querus spp. The authors investigated paint coating of 1 wooden ware to find out No.4 of the exterior and No.3 of the interior and about 100㎛ thickness of the lacquer layer. The. conservation treatment was done to immerse wooden ware into high molecular PEG#3,350 in water solution (10 ~ 45%) and to give physical strength and to do vacuum freeze drying.

In this paper we analyse how school mathematics terminologies have been changed from the syllabus period to the 2007 curriculum. For this we survey the school mathematics terminologies which have been used since the syllabus period on the 2007 curriculum basis, analyse changes in expression of those, and look through to the characteristics of mathematics terminologies for each curriculum period.

Among the changes of the Curriculum from the liberation to the present, the biggest change in the highschool geography course appeared during the period from the Period of Syllabus to the 1st National Curriculum. More specifically, during the 1st National Curriculum the highschool geography course which previously had three subjects, 'Natural Environment and Human Lives', 'Human Geography', 'Economic Geography' was reduced to one subject, 'Human Geography.' In addition, while some contents related with astronomy, geology, and biology had been contained in the physiography course, they were left out from the human geography course of the 1st National Curriculum. This reduction of the geography course was related to the context that earth science was newly established in the 1st National Curriculum. Originally the draft plan released in June, 1953, which was 10 months before the formal time allotment criteria list had been made public, contained 'Physical Geography' instead of 'Earth Science'. What is sorry is that the name of 'Physical Geography' did not remain and was changed to 'Earth Science'. The underlying causes of the crisis the geography education is now facing are the reduction of Physical Geography and the emergence of 'Earth Science' during the 1st National Curriculum. To overcome the present crisis, the subject of geography should be changed more meaningful one based on the comprehensive perspective and academic product that geography has accumulated.

Resistance to various diseases of Korean native varieties were investigated in field. The results obtained are summarized as follows: 1) The varieties Ubangtchio and Osib-eubthio were moderately resistant to black shank, but Suantchio, Usultchio and Gwangtchio were slightly resistant. Dixie Bright 101, $H_2$ and Bright Yellow 4 were more resistant to black shank than any of the Korean native varieties. 2) Mokgitchio, Ubangtchio and Osib-eubtchio were moderately resistant to black root rot, but Useultchio Suantchio and Hoetchio were susceptible than Others. 3) Muktchio, Hoetchio and Ubangtchio were slightly resistant to wild fire. 4) Osib-ebthio was highly resistant to brown spot, but Ubangtchio, Hyangtchio and Mokgitchio were moderately resistant and Useultchio was susceptible to brown spot, but it was resistant than Bright ellow 4 or Bernhart 1000-1. 5) Hyangtchio was slightly resistant to CMV-Y. According to these results, except Virus disease, Ubangtchio was resistant to all of the above mentioned diseases. Osib-eubtchio, Hoetchio, Hyangtchio and Suantchio showed proferable disease resistant and these might be well utilized as breeding materials.

Archaeological investigations carried out in the Chilgok Housing Land Development Area have identified large-scale settlements from the Bronze Age and Three Kingdoms periods. The settlement site in Dongcheon-dong, Daegu was found to include sites of pit dwellings, buildings with elevated floors, stone coffin tombs, wells, catchment basins, stone mounds, furrows, cropland, moats, and river channels. These findings offer insight into diverse aspects of settlements during the Bronze Age. This study analyzed the species of trees that produced the materials for eight wooden artifacts excavated from a Bronze-Age river channel site. The analysis identified two examples of Pinus spp., two examples of Abies spp., and four examples of Quercus sp. The three artifacts of undetermined use were made using wood from Pinus spp. and Abies spp. Among the five artifacts identified as building components, one was made from Pinus spp. and four were made from Quercus sp.

Aggravation of natural environment, improvements in income, internet diffusion, spread of five-day work a week, and population aging seem very different from each other. However they boil down to consumption. These culture patterns are changing into environment-friendly and productive housing culture. In other words, people might tend to have frequent contacts with not only environment-friendly housing in bustling cities but also woods that is environment friendly materials in their leisure time. In the period of people young and old alike are in favor of woodcrafts, this study was conducted for giving information to who speicalized in woodcrafts. Furthermore, the study shows that other countries also added grain and figure to woodcrafts for visually appealing.
