Writings of gifted students were classified by the writing analysis protocol built on the scientific inquiry process and writings of scientific journals. These writings were classified 7 types based on the existence of tentative explanations and types of conclusion. In addition the writings were classified by linear form, double linear form, supporting-conclusion form based on the number and position of writings. The characteristics of writings show that, first, the tentative explanation is located at the beginning and the drawing conclusion at the end of articles. Secondly, students prefer the linear form writing to explain their logics. Finally, supporting-conclusion writings are shown when answers of question is written only in the drawing conclusion without estimation.

본 연구는 기존 RPG에서 주요한 재미 요소로 기능하던 성장 모티프가 MMORPG(Massive Multi-user Online Role Palying Game)에서 어떤 식으로 변형되어 나타나는 지 살펴본다. 성장과 역할 수행을 통해 재미를 얻는 게임인 MMORPG는 성장 서사에서 많이 나타나는 구조인 여정형 혹은 탐색형의 구조를 보편적으로 차용하고 있다. 그러나 기존 서사물에서 성장 모티프가 정체성 찾기와 같은 내면적인 변화를 나타내기 위해 구조를 차용하는 반면, 게임에서는 위의 구조를 통해 얻은 성장의 결과물을 수치의 증가나 외적 형태의 변화를 통해 나타낸다. 즉, 경험치나 아이템을 통해 성장이 수치화되어 나타나는 것이다. 이는 여정형 탐색담이라는 성장 서사의 보편적 구조에서 게임적인 특수성이 더해진 것이라 할 수 있다. 성장 소설만의 서사적 유형이란 바로 주인공의 변화 양상이 미숙에서 성숙으로, 불완전에서 완전으로, 결핍에서 충족으로 변화하는 과정을 담고 있는 이야기적 특질을 의미한다. 그러한 미숙하고 불완전한 존재가 변화하게 되는 계기와 과정, 그리고 그 결과로 구조화된 유형적 특질을 갖고 있는 소설 양식이 성장소설이라 할 수 있는 것이다. 이러한 구조화된 유형적 특질은 신화나 민담에서는 탐색담이나 여행담으로 나타난다. 게임에서의 성장은 캐릭터의 성장과 직결된다. 본격적으로 플레이어와 동일시되어 성장을 대리 경험적으로 체험하는 것은 D&D 온라인을 거쳐, 현재 MMORPG의 형태를 구현해낸 울티마 온라인이 이후부터이다. 세부적으로 구현된 세계와 온라인을 통해 생성된 방대한 네트워크 안에서 플레이어는 자신과 동일화된 캐릭터를 플레이하면서 대리경험을 하게 된다. 즉, 플레이어가 캐릭터의 성장에 작용하는 여러 가지 변수를 선택하고, 조작해가면서 자신만의 캐릭터를 생성해 나가면서, MMORPG가 구현하는 게임 세계에 구성원이자 일원이 되는 것이다. MORPG는 기존의 RPG의 선형적인 성장에 비해 복합적인 양상을 보여준다. 문화에서의 성장 서사에서 일반적으로 발견되는 여정형의 탐색담은 개발자 서사인 배경 스토리에서 나타나며, 레벨시스템과 이에 따른 공간의 배치에 따라 플레이어에게 직접적인 영향'을 끼친다. 영속적인 세계와 플레이어 간의 상호작용을 통해 일어나는 사용자 서사는 완결된 형태의 캐릭터를 무의미하게 만든다. 플레이어는 비선형적인 성장을 끊임없이 계속하게 되는 것이다.

Metadata is data about data that is used to mange data itself. As applications based on DBMS are increased, it is suggested that metadata model and metadata interchange model to manage metadata in DBMS. but metadata which is in the form of XML (eXtensible Markup Language) document is generally stored into RDBMS. Therefore In this paper, as for the method to store metadata of RDBMS into OODBMS, we design metadata model, metadata interchange model and implement new repository system. The metadata of RDBMS is translated into in the form of XML Document and integrated into XML Data Server on OODBMS, eXcelon and executes retrieval metadata information about RDBMS by XQL(XML Query Language). So It is possible to searchm edit a metadata. The metadata of XML documents stored in eXcelon is easily made to be printed in web browser by applying a XSL (extensible StyleSheets Language). So we can have a detail information about property of metadata in DBMS.

The Apartment resident's make-up of a family and residing preference are diversified by the change of lifestyle through the elevation of economy level and residing level. Accordingly, the remodeling and the early rebuilding for the satisfaction of a life cycle and a life style are increasing, and "Variability" that is the concept of Open Housing was emphasized as a central of residing plan in the apartment. Although apartments which select the space variability to the residing space are increasing gradually, the optimum composition structural system with space variability that satisfies the structure stability, the economical efficiency and the resident usability is not developed. The method of a study was progressed by a comparison and an analysis on each system with estimation elements through analyzing the development process and the special quality of existing composition structural system with space variability in the apartment. This paper offered the improvement direction on the current composition structural system with space variability for the development of modularizing system that is correct in domestic real condition.

We investigated the optimum salinity and temperature conditions for mass culture of ultra-small rotifer Synchaeta kitina. In the salinity experiment of ranging within 5 and 30 psu, the population growth of S. kitina increased continuously up to 20 psu, and then decreased over 20 psu. Their maximum density showed 390.1 inds./mL at 5 psu. A pre-reproductive phase was shortened in low salinity than high salinity. Also, the maximum offsprings and maximum lifespan and lifespan of the female were 13.4 inds. and 5.9 days, respctively at 5 psu. In the temperature experiments of ranging within 16 and $32^{\circ}C$, the population growth of S. kitina increased continuously up to $24^{\circ}C$, and then decreased over $24^{\circ}C$. The highest maximum density showed 492.8 inds./mL at $16^{\circ}C$. Their offsprings increased significantly with temperature decrease, and the maximum number of offsprings per female was 9.2 females. at $16^{\circ}C$. Their lifespan increased with temperatures decrease and the longest lifespan was to 5.5 days at $16^{\circ}C$. From these results, we conclude that the optimum culture conditions of S. kitina is 5 psu and $16^{\circ}C$.

This article deals with some issues with respect to the Mahan pottery excavated from the tombs. Pedestal jars with cover, small round-bottom jars, cylindrical pottery etc. had appeared in the interaction with the northern region in the dimension of the southern Korean peninsula. Especially, these relics had an important role at the route connecting the midwest region, Chungcheong(忠淸) inland and Yeongnam(嶺南) region. By this stage, the iron culture was similar to each other in the southern Korean peninsula. In addition to the inland route, the coastal passage along the west coast seems to have been used. Such signs are found in cylindrical pottery and Pedestal jars with cover. It was probably a natural phenomenon that the most powerful forces of Mahan appeared at this crossroad of cultural exchange. The unique style of Mahan pottery such as double-rim pottery had been established since the third century. After the third century, Mahan pottery varied by region depending on the tomb style. The difference roughly matches with the variations of the tomb style. But at the region of Bungumyo(mounded tomb), specific pottery such double-rim pottery had been prevalent than in other regions. And a specific style had been used in a narrow range. The pottery spread to the neighboring regions in the course of interaction and were also used in ritual practices.

Since the introduction of Israeli carp into Korea for farming in 1973, there are no breeding studies on developing Korea Israeli carp (domestic) so far. This study performed gene-based cross-breeding studies to restore genetic diversity of lowered Israeli carp through continuous inbreeding, and for rapid growth and better scales. This study produced four cross-breeding groups (F1) using Koean Israeli carp and Chinese Songpu mirror carp for the improvement of growth and scale of Israeli carp in Korea. And mating scheme for breeding groups was set in consideration of the morphological analysis and genetic distance of broodstock. In addition, this study used microsatellite markers and genotype data to analyze genetic diversity and parentage analysis. As a result, the average N_A and H_E values of Korean select broodstock are 8.3 and 0.743, and F1 is 13.0 and 0.764. This study shows that the genetic diversity of F1 has been recovered over Korean Israeli carp through breeding between Korean Israeli carp and Chinese Songpu mirror carp. Common Israeli carp in Korea reached 1.7 kg in 17 months, and improved Israeli carp reached to 2.2 kg. The KC (Korea×China, KC) group was 2.52 and broodstock group was 3.15. F1 showed lower scale score (0.63) than broodstock. The improved carp (F1; CK, KC) had 20% better scales than the parent group (F0), which improved 27% in weight and 25% in scales compared to common Israeli carp. The Israeli carp developed by the genetics-based breeding grew quicker and had improved genetic diversity and fewer scales, which will be of great value for Korean Israeli aquaculture industry due to good marketability.

To understand the variation of macro benthos community according to the installation of structure and topographic placement in the shellfish farm on tidal flat, the practical example of the tidal shellfish growing area at Namsung-ri Goheung was observed. The results of the research for the field observation were summarized as follows. (1) The ground gradient of the shellfish farm was very flat below about $1^{\circ}$. The shellfish farm ground took the shape of $\sqcup$ from the shoreline to the place of 150 m seawards, and the shape of $\sqcap$ from there to the low tide line. During ebb tide, the $\sqcup$ shape ground stored the sea water, and the $\sqcap$ shape ground was supposed to act as the effect factor to leak slowly or to prevent the outflow. (2) The oyster shell bag or the type of riprap wall as the boundary in the shellfish farm was classified into five types. The air exposure time and flooding time were 181 and 434 minutes, respectively. (3) In the numerical experiment, the deep-sea water wave coming in the study area had 0.5 m of maximum wave height to show the very stable conditions and the wave direction pattern of S-direction was dominant at Naro great ridge, and SE, SSW and S-direction were distributed strongly around the shellfish farm. (4) By the grain size analysis, the sediment around tidal flat consisted of gravel 0.00~5.81(average 1.70)%, sand 14.15~18.39(average 13.23)%, silt 27.59~47.15(average 30.84)% and clay 35.79~55.73(average 36.19)%, and the sediment type was divided into (g)M(lightly gravelly mud), sM(sandy mud) and gM(gravelly mud) by Folk's diagram. (5) The macro benthos community survey conducted in this site in January, 2010 showed that 1 species of Mollusca, 8 species of Polychaeta and 2 species of Crustacea appeared, and 11 species occupying over 1% of total abundance were dominant.

During 1993 and 1994, some mortalities of flounder(Paralichthy olivaceus) fry were recorded in several fish farms and viruses were isolated from 3 of the farms. Electron microscopic examination revealed that the virus particles were hexagonal and unenveloped with an average diameter of 50 to 55nm. Serological and molecular properties of these isolates were examined. The viral RNA and polypeptides patterns on electrophoresis, as well as neutralization test results, showed that these isolates were birnaviruses and two were closely related to infectious pancreatic necrosis virus(IPNV) serotype AB and one was to IPNV serotype SP. This is the first isolation of birnaviruses from marine fish in Korea.
