Derivation of modern products from the by gone age has contributed much for the new modern living. It has been generally recognized that the various ethnicities in Borneo with different backgrounds had made Borneo a place of cultural diversity. However as time passed, most indigenous products are no longer in used or are stored in poor condition. Most products nearly aged over a century are still in a good condition with invaluable sentiments. Indigenous product is an artifact that had been designed and used by certain community of people such as tools, clothing, crafts and goods. Each design may have its own identity to the community. Some of the indigenous products which are no longer in use at present are kept by the community as their collections. The research reveals similarities in the interests of indigenous products, concerns and realities of indigenous communities from the different regions. The study suggests that learning about indigenous materials, such as hand-made products and machine-made products is necessary for the local industry to develop a product identity that is distinctly local. Most indigenous products show evidence of connections to old traditions, yet are new to the design market.

To study ecological characteristics of Cyperus serotinus occuring in Korea its propagules were collected from 6 locations from the northern part to the southern part of Korea (Chuncheon, Suweon, Iri, Jeonju, Gwangju, Milyang) in 1981, cultured and replanted 4 times (May 20, June 5, June 20, July 5) in 1982. They flowered from August 10 to August 29 in the plants planted on May 20 and from August 22 to September 4 in the plants planted on July 5. Plant height, number of tillers and top fresh weight were 85-100cm, 375-1,500 tillers/$m^2$ and 500-1,750g/$m^2$, respectively, when they were planted on May 20, and 58-67cm, 300-625 tillers/ $m^2$ and 125-250g/$m^2$, respectively, when they were planted on July S. Weight of seeds and number of rhizomes per plant were 20-50g/$m^2$ and 20.75-61, respectively, whey, they were planted on May 20, and 5-17.5g/$m^2$ and 51.5-80.25 when they were planted on July 5. Local collections showed. the same morphological characteristics at the level of species identification, but there existed variations among the local collections. Cyperus serotinus from Chuncheon and Suweon were longer in the length of inflorescence, than those from Gwangju and Milyang and rhizomes from Chuncheon and Suweon were thicker than the others. Each of local collections may be regarded as different ecotype based on the above mentioned differences in morphology, growth and flowering response to the planting date. The results appear to imply that Cyperus serotinus weeds occuring in various locations of Korea are different one another in competitive ability with rice crop.

In this study, a total of 25 lines consisting of five native ginseng collections from Poonggi area, five lines from Geumsam area and 15 varieties were analyzed and clustered for the selection of Poonggi native ginseng in Korea using DNA markers. The results indicated that the long cluster distance were observed between the collections of 331002, 331004, 331005, 331007 and 331026 from Poonggi area, and the collections of 332009, 332021, 332046, 332050 and 332066 from Geumsan area because of the sensible differences on the number of leaves per stem, stem color and petiole color. Thus, the collections from Poonggi area with specific characters consisting of one stem per plant, five leaves per stem and broad elliptic leaflet shape were finely classified using nine primers including OPD05, OPD20, OPG17, OPH05 and so on. In this study, the collection of 331007 from Poonggi area was considered as the respective collection with above characters. Thus, the nine primers such as OPD05 and so on, will be used to select the Poonggi ginseng in the future studies.

The factors of local disappearance and a plan of restoration fer Parnassius bremeri from Okchon-gun, Chungchongbukdo, Korea, were investigated. The population of this butterfly from Okchon-gun was much more abundant than the other areas of Korea in the past. But only two adults were observed in 1997 at this site and no more observation was made in 1998. So we considered that Parnassius bremeri is disappeared from this area. To know the factors of local disappearance of this species, we analyzed data of the monitoring from seven localities of Okchon-gun from 1990 to 1998 and also checked 252 specimens from this area by several collections. As a result of it, the habitat changes by recent road constructions and the frequent collecting activity around this area are shown as the factors for the local disappearance of this species. We are intending to establish the programs for restoration of Parnassius bremeri in Okchon-gun. Firstly, the breeding plan of this species was designed by investigation on life cycle. Secondly, the environmental conditions among seven localities were compared and the suitable places of the restoration were selected. The most suitable localities for restoration by this study were of two localities, Dongrakjeong and Jangwahri, which are considerd as highly successful breeding places in the view of growth condition of host plant.

The Purpose of this study is analyzed that (l) How the public Libraries under the Japanese Rule since the end of the Yi-Dynasty were recepted and generated by the people and (2) How they were organiged and managed. (3) Also it examined that how they affected the development of the libraries of today. 1. The following are the analyzed results: Three types of the public Libraries under the Japanese Rule for a period of 36 years engaged busily in colonization were Private's Public Libraries, Local Self-Government's Libraries and the Central Governmental Libraries, and were in order established. 2. They were eatablished by individuals, Confucian School Foundation, Young Men's Clubs, School Associations, Korean brethren residing abroad, or The Press Centering around the Local Self-Governments and the Japanese Government-General. 3. In 1932 of the period of the Japanese Rule, the number of Libraies gained the summit and reached 80 Libraries. The Public Libraries including the Central Governmental Libraries remained in existence until the end of the War had been kept up the functions of the Libraries, but the Private Libraries operated by the Koreans were very small and poor. As a result, most of them were closed up and some Libraries transferred their controls to the public. Until the end of the war, only a little over 10 Private Libraries were Kept up. From the aspects of it's organization system, the most of their libraries replaced their chief librarians with non-professional county-headmen or Local supporters. From the aspect of collections, they wate mainly consists of Japanese books for the proper quidance of the public thought based on the ideology of Japanese Rule to Korea and on the industrial promotion rather than books about Koreanology or Western books. At that time, the Library users were with the jobless men and students as the central figures. And the next ranking by the social position of readers was children, farmers, merchants, industrialists, public servants, miscellaneous and educators. Their reading tendencies laid stress on linguistics and literature, physical sciences and medicine, While the reading trend of military sciences and medicine, while the reading trend of military sciences and engineering were very inactive. This was because the Japanese Government-General had not kept the military collections on file. Besides, they were reluctant to make Korean's learn the professional knowledge and so the main reference materials of technology not provited. Most of the Libraries put practiced in circulation services were very important circulation in withinder of the reading room rather than in outside of the Library building. On the other hand, their circulation services has above came with many limitations. As stated above, the public Libraries' managements and activitives under the period of Japanese Rule were the way and means to achive the colonial and imperialistic purpose of the Japanese Empire.

Seed characteristics such as seed size, seed shape and cotyledon color are important in relation to processing and cooking of soybean. Seed shape, water absorption rate, and alkali digestibility were evaluated for 28 local black soybean collections. Water uptake rate was low in small seed size at low temperature(5, 2$0^{\circ}C$). However, higher water absorption rate was observed at high temperature(40, 6$0^{\circ}C$) regardless of seed size. When seeds soaked up water, it reached to water absorption equilibrium after 10 hrs below 2$0^{\circ}C$, within 10 hrs at 4$0^{\circ}C$, and around 4 hrs at 6$0^{\circ}C$, respectively. Significant positive correlations were observed between 100 seed weight and length, width and thickness of seed, respectively. Alkali digestibility value(ADV) was higher in large seed group than in small seed group. Among seed characteristics, significant positive correlation was shown between ADV and 100 seed weight, length, width, thickness and hilum length of seed, respectively. Soybean seed with green cotyledon showed higher ADV than that with yellow cotyledon.

One of the best means to safeguard the confidentiality, security, and privacy of an image within the IoT-Cloud is through encryption. However, looking through encrypted data is a difficult process. Several techniques for searching encrypted data have been devised, but certain security solutions may not be used in IoT-Cloud because such solutions are not lightweight. We propose a lightweight scheme that can perform a content-based search of encrypted images, namely EEIRI. In this scheme, the images are represented using local features. We develop and validate a secure scheme for measuring the Euclidean distance between two descriptor sets. To improve the search efficiency, we employ the k-means clustering technique to construct a searchable tree-based index. Our index construction process ensures the privacy of the stored data and search requests. When compared with more familiar techniques of searching images over plaintexts, EEIRI is considered to be more efficient, demonstrating a higher search cost of 7% and a decrease in search accuracy of 1.7%. Numerous empirical investigations are carried out in relation to real image collections so as to evidence our work.

This experiment was conducted to select and rear the adaptable cultivar which isused for various purpose and to build a year-round cultivation using with characters of aerial part and analysis of chemical components in 28 local cultivar of Artemisia princeps Var. The growth of aerial part, which are stem length, stem diameter, no. of branch, node, leaf size and leaf pubescence, in north local cultivars was more vigorous than those of south local caltivars. Fresh weight of "Myeongcheonssuk " was highest in local caltivars, and in view of local area, local cultivars which was collected from Iri Si and Euiseong Gun was shown the highest fresh weight. Local cultivars as mentioned above had a characters with plenty of leaves, nodes and pubescence of leaf is long. In chemical components of leaves in morth cultivar, content of N, MgO, Zn, Cu, Mn was high, while $P_2O_5,\;K_2O$ in middle local cultivars, Fe in south local cultivars. The more content of carbohydrate in leaves was high, the content of $K_{2}O$ had a increasing tendency. In local cultivars which was collected form Iri Si and Euiseong Gun with the highest fresh weight, content of $N,\;P_{2}O_5,\;K_{2}O$ was high, on the other hand content of MgO, Zn, Ca, Mn, Fe, was low in leaves of Artemisia Princeps Var.
