This study was conducted to identify the attributes constituiting Korean social support and to validate the results of the previous study ‘Search for the meaning of social support in Korean Society.’ The informants were 41 Korean middle-aged women in three cities Seoul, Daejun and Daeku. The data were collected through indepth interviews using the interview guide from Jun. 1994 to Jun. 1995. The interview guide was developed in the simulated situations of ‘Stroke attack’ which expected to be in need of social support. The women were asked to answer what they felt and the appropriate terms representing the situations. Data analysis were conducted by content analysis. Consequently, the Korean social support pyramid was modified as follows ; Support is the apex of the pyramid. The four sides of the pyramid are made up of ‘Jung’(Bound by ties of affection, regard or shared common experience, Connectedness), Do-oom(both emotional and material help), Mi-dum(Faith or belief in) and Sa-Rang(Love). The base of the pyramid is ‘yun’(the basic network of relationships in Korean culture) that connote the meaning of Eunhae(Benevolence), Euimu(duty, responsibility) and Dori(obligation).

In this paper, we propose a fast motion estimation algorithm which is important in performance of video encoding. Even though so many fast algorithms for motion estimation have been published due to its tremendous computational amount of for full search algorithm, efforts for reducing computations in motion estimation still remain. In the paper, we propose an algorithm that reduces unnecessary computations only, while keeping prediction quality the same as that of the full search. The proposed algorithm does not calculate block matching error for each candidate at once to find motion vectors but divides the calculation procedure into several steps and calculates partial sum of block errors. By doing that, we can estimate the minimum error point early and get the enhancement of calculation speed by reducing unnecessary computations. The proposed algorithm uses smaller computations than conventional fast search algorithms with the same prediction quality as full search.

This paper makes it possible to search videos based on sentence by improving the previous research which automatically generates rich metadata from videos and searches videos by key words. For search by sentence, morphemes are analyzed for each sentence, keywords are extracted, weights are assigned to each keyword, and some videos are recommended by applying a ranking algorithm developed in the previous research. In order to evaluate performance of video search in this paper, a sufficient amount of videos and sufficient number of user experiences are re required. However, in the current situation where these are insufficient, three indirect evaluation methods were used: evaluation of overall user satisfaction, comparison of recommendation scores and user satisfaction, and evaluation of user satisfaction by video categories. As a result of performance evaluation, it was shown that the rich metadata construction and video recommendation implementation in this paper give users high search satisfaction.

This paper introduces a novel neuro-fuzzy system based on the polynomial fuzzy neural network(PFNN) architecture. The PFNN consists of a set of if-then rules with appropriate membership functions whose parameters are optimized via a hybrid genetic algorithm. A polynomial neural network is employed in the defuzzification scheme to improve output performance and to select appropriate rules. A performance criterion for model selection, based on the Group Method of DAta Handling is defined to overcome the overfitting problem in the modeling procedure. The hybrid genetic optimization method, which combines a genetic algorithm and the Simplex method, is developed to increase performance even if the length of a chromosome is reduced. A novel coding scheme is presented to describe fuzzy systems for a dynamic search rang in th GA. For a performance assessment of the PFNN inference system, three well-known problems are used for comparison with other methods. The results of these comparisons show that the PFNN inference system outperforms the other methods while it exhibits exceptional robustness characteristics.

This study is to search for the characteristics of spatial structure and elements of architectural composition on the housing and village in Nampeong Moon's Bonli Ma-Yul which formed. from the late nineteenth century to the the early twentieth century. This village had as many as characters of spatial and architectural structures of traditional clan villages previous to the late nineteenth century, but showed housing alternations on social changes of late Cho-Sun dynasty. Main points of these were as follows; 1) As the main doors of the housing were located on the right of Sa-Rang-Chae, men and women's moving lines of coming in and out were not nearly divided. 2)As korean veranda on the right and left, and the front and rear of those were set up, the demand on extension of room area coping with changes of life was satisfied.

In this Study, the search and analysis for the contents of the mass media, especially, such as newspaper articles, broadcast campaigns, broadcating advertisings, the Internet, etc, are accomplished under the assumption that the cause of the negative and fragmentary images about Africa holds a place in Korea's heart resulting from Korean mass media. Africa was seen as not only the continent of famine and diseases, but also a safari and the Nature's repository. However, these images are only the fragments of information about the African continent. So, we have to understand and recognize the origin of Africa in aspect of its learning and the mythology as well as the truth of the African as modern human origins. Moreover, we have to do our endeavor to have a good perspective about Africa as our future partner somewhat less than the wretched continent that we applaud their effort to the pursuit of stability and the development in terms of their modern cities, economy and politics and we have to aid and send relief cargoes simply.

The purpose of this paper is to examine some effects of four menu types: icon menu, icontext menu, pulldown menu, and bar selection menu. Each have been mainly used with hypermedia instruction, learners' metacognition on their errors, menu search time, and scholastic achievements. A further purpose of this paper is suggest some strategies for enabling each learner to select menus more efficiently in order to enhance the learner's own learning effectiveness in hypermedia instruction. There were 100 college students selected as subjects for This study. They had never had experience in Hanoi hypermedia instruction. They were required to use four menu types at random in this experiement. The results of this study are as follows. The menu types had a significant effect on the low metacognition regulation group. Icontext menu types, especially, had a significant effect on achievements. In constrast to this, the menu types did not have any significant effect on the high metacognition regulation group.

By-products of marine organisms including salmon, skate, flatfish, and yellow goosefish were investigated to search for new source of chondroitin sulfate (CS). Agarose gel electrophoresis with chondroitinase depolymerization showed that purified chondroitin sulfate did not contain any other glycosaminoglycans. 1H-nuclear magnetic resonance (NMR) spectra were acquired to confirm the structure and purity. The average molecular weight ranging from 22 to 64 kDa was determined by high performance size exclusion chromatography. Disaccharide compositions and purities were determined by strong anion exchange-high performance liquid chromatography (SAX-HPLC) after chondroitinase ABC depolymerization. SAX-HPLC data exhibited that the purity was from $81.7{\pm}1.3$ to $114.2{\pm}2.5%$ and the yield was from 1.3 to 12.5%. All analytical results indicate that salmon cartilage, skate cartilage, and yellow goosefish bone could be promising sources of CS to substitute shark cartilage CS in commercial neutraceuticals.
