This paper proposes an intelligent search modeling using avatar agent. This system consists of some modules such as agent interface, agent management, preprocessor, interface machine. Core-Symbol Database and Spell Checker are related to the preprocessor module and Interface Machine is connected with Best Aggregate Designer. Our avatar agent system does the indexing work that converts user's natural language type sentence to the proper words that is suitable for the specific branch information retrieval. Indexing is one of the preprocessing steps that make it possible to guarantee the specialty of user's input and increases the reliability of the result. It references a database that consists of synonym and specific branch dictionary. The resulting symbol after indexing is used for draft search by the internet search engine. The retrieval page position and link information are stored in the database. We experimented our system with the stock market keyword SAMSUNG_SDI, IBM, and SONY and compared the result with that of Altavista and Google search engine. It showed quite excellent results.

With the emergence of the new era of the 4th industrial revolution, compute-bound workloads with large memory footprint like big data processing increase dramatically. Even in such compute-bound workloads, however, we observe bulky I/Os while loading big data from storage to memory. Although file I/O cache plays a role of accelerating the performance of storage I/O, we found out that the cache hit rate in such environments is not improved even though we increase the file I/O cache capacity because of some special I/O references generated by compute-bound workloads. To cope with this situation, we propose a new file I/O cache management policy that improves the cache hit rate for compute-bound workloads significantly. Trace-driven simulations by replaying file I/O reference logs of compute-bound workloads show that the proposed cache management policy improves the cache hit rate compared to the well-acknowledged CLOCK algorithm by a large margin.

For an efficient management and utilization of marine biodiversity information, we made an attempt to develop the Korea Marine Biodiversity Information System (KoMBIS), building a species name inventory of Korea marine organisms. The inventory includes 17 organism groups: phytoplankton, zooplankton, algae and halophyte, sponges, cnidarians, rotifers, nematodes, bryozoans, brachiopods, molluscs, echiurans, annelids, arthropods, echinoderms, urochordates and fish. The species names were collected from 37 different references and reviewed for validity by taxonomists, which resulted in 9,798 valid names in addition to 1,845 synonyms. The Korea marine species inventory is the first one of this kind, for previous Korean species name inventories were mostly composed of terrestrial and freshwater organisms. KoMBIS, the information system developed, contains not only the species name but also information on morphological and ecological characteristics such as distribution, DNA barcode, and references. This system is convenient for the inputting of new data and servicing users through the internet, so that management and utilization of the biodiversity information is more efficient. Linking the DNA barcode data with species information provides an objective measure for identification of a species, which accommodates the recommendation of Consortium for the Barcode of Life, and makes the Korea marine biodiversity information compatible with international databases. Considering the frequent exchange of marine organisms internationally via ballast water and such issues as climate change, this information system will be useful in many areas of marine biodiversity.

단백질 분자는 포켓 위치에서 유사한 형상을 갖는 다른 분자와 결합되며, 포켓은 단백질 분자의 형상을 묘사하기 위한 참조 점으로 사용될 수 있다. Harris 검출기는 2 차원이나 3차원 객체의 특징 점을 검출하기 위해 널리 사용된다. 특징 점들은 데이터의 변화율이 높은 영역과 포켓 영역에서 발견된다. 일반적으로 포켓 영역은 함몰된 형태로 존재하기 때문에 이 영역에는 다른 영역에 비해 다수의 특징 점들이 존재한다. 특징 점들을 포함하는 voxel cube를 연속적으로 분할함으로써 포켓 영역을 발견할 수 있었고, 포켓 영역의 중심 좌표와 특징 점들 간의 Euclidean 거리를 계산한 후 이들을 크기순으로 정렬 하였다. 정렬된 거리에 대한 그래프는 단백질 분자의 형상과 특징 점들의 분포에 대한 정보를 제공하므로 단백질 분자를 형상별로 분리 할 수 있었다. 본 연구에서는 인위적인 잡음을 단백질 분자에 추가하여 형상이 왜곡된 분자를 얻었고, 왜곡된 분자에 대해서도 95 % 이상의 정확 도로 형상을 인식 할 수 있었다. 정확한 단백질 분자의 형상 인식은 분자들 간의 결합특성을 예측할 수 있는 중요한 정보를 제공한다.

Recently, the use of electronic drug information databases has been increased alternative to printed references. However, databases vary widely in quality and quantity of drug information provided and many questions have arisen about their accuracy, completeness, and reliability. This study was designed to compare and evaluate the drug information contained in four Korean drug information databases which are available on CD-ROM and internet. Four Korean drug information databases selected to be evaluated were eKIMS, Datapower, KPA Standard Drug Information and Korean Drug Formulary. Databases were searched and evaluated from August 10 to September 30, 2000 by the same trained searcher to minimize the bias. The database evaluation form was developed for objective evaluation of each databases in terms of credibility of database, convenience of use and other characteristics. The second form was developed for quantitative and qualitative assessment of the drug information provided by the databases. The results of the study showed that there were no significant differences in 4 databases in terms of convenience of use and other characteristics. However, for credibility of databases, Korean Drug Formulary was significantly superior to all other databases (P<0.05). It showed that information provided by Korean Drug Formulary was the best in terms of pharmacokinetics, chemistry, comparisons and eKIMS was the best in terms of drug identification (P<0.05). For accuracy and completeness of information provided, the study could not find a significant difference between 4 databases (P>0.05).

Though old generation criticizes on costume play that it is accepted by young generation without any criticism, it is gaining popularity and is settled with unique Korean characteristics. The study is to understand the characteristics of costume play and investigate on the attitude of costume players enjoying it. For this study, a survey was conducted on costume players who order tailor-made costumes or rent them by using references, existing papers and internet sites. The results are as follows. 1.37% of costume players live in Seoul and Gyeonggi area, 37% in Gyeongsang-do and Busan with 21% in other areas. Two areas shows higher rate than any other regions, as Seoul Comic and Busan Comic are held regularly and there are faster exchange with Japanese culture in these areas with enough money 2. Among costume players, female accounts for 73.7% with 26.3% male. It shows that female likes costume play more than male. It is because woman responds actively to what she likes than man does. The number of male is steadily increasing. By age, high school student is 40%, middle school student is 36%, older than 20 is 16% with 3% of elementary school student. 3.61% of them like the reproduction of character costumes, 14.7% like Pancos and another 14.7% likethe reproduction of character costumes and creation. 69.5% participates in costume play both in groups and individuals, 26.3% in groups and 4.2% in individuals. 45.3% participates in comic more than 8 times in a yew, 43.2%, 1-2 times and 11.6%, 3-4 times. Mostly they want $50,000{\sim}80,000$ won costume. 4. on the criticism of old generation that costume play is nothing but the imitation of Japanese culture, 87.4% of the respondents answered 'absolutely not' They think costume play is one of their favorite cultures. 5. on the parents response to costumeplay, 87% of the respondents answered 'Ethey understand', 13% said 'they cannot understand and dissent'. The respondents said costume play didn't affect their school records with 25% respondents who said they got better grades.

The purpose of this thesis is presenting desirable design of uniform which could reflect high school girls' demands with the researches on their consciousness of fashion and actual state of uniforms. Methods to accomplish this research include first, examinationson characteristics of high school girls and their consciousness of fashion with relevant articles, second, interviews with designers from major domestic uniform brands - ELITE, IVY, SMART - and third, analysis on related internet sites. Practical researches are followed by design analysis and proposal of improvement on high school girls' uniform, accompanied by collection of photographs from field studies, major uniform brands' shops and uniform related internet sites. Korean high school girls in the digital era are able to express themselves in each different fashion with own individuality, preference or intention, as they are particularly interested in clothes or their appearances. Their consciousness of fashion became visible in a shape of negative attitude and dissatisfaction with uniforms due to its out-of-date design, lack of features and inconvenience in action. Besides more than half of high school girls already experienced reforming it for better looks. As a result of current analysis on references of uniform designs, various levels of refinement were noticed even in uniform of similar details, design, fabric textile and color due to differences on size & length of jacket collar, dart, cutting line, size of details, decorative line, easiness in fit, length of clothes, and etc. To provide students of more refined and desired designs which reflect their demands, current uniforms are to begin acquiring delicate changes with present vogue and feature such as size of details, silhouette, cutting line, decorative line and etc. In addition newly designed uniforms are to present desirable design with image of refinement and neat as they actively comprehend students' needs within its symbolic, functional, economic and aesthetic characteristics by nature.
