Computer technology pursuing more innovative image than before, makes some characteristics which distinguishes the digital fiction film from the analogue fiction film. One hand, the split screen in analogue film aides the development of drama in the aspect of narrative, on the other hand, it controls the psychology of spectator. The composite image in digital fiction film by computer graphic, and elaborated digital editing show many innovation in the field of audiovisual. In this context, I would like to remark on the digital film (2003) directed by Ang-Lee. In , the split screen and the composition of the fast transiition of shots in the scene of laboratory were created by computer graphic program for special effects. As visual special effect plays an important role in digital film, its narrative space creates a space which is distinguishable from that of analogue film.This can be an example which says a lot for the special aspect of digital narrative.

본 논문에서는 손상선박의 안전대책에 관한 연구의 일환으로서, 황천항행중인 선박이 충돌, 좌초 등 원인에 의해 조종불능이 되었을 때를 가상하고, 예선ㆍ피예선계의 침로안정성에 미치는 풍향, 풍속, 예항삭의 길이의 영향을 이론적으로 검토하고, 풍압하에서 피예선을 다른 안전한 장소로의 예항에 대하여 하나의 지침을 주는 것을 목적으로 한다. 여기에서 실선은 Hulk carrier와 Passenger liner를 모델로 삼았고 외력으로서는 파도가 충분히 발달되지 않은 바람이 부는 초기상태 혹은 저속으로 항행하는 상태를 고려하여 바람의 영향만을 취급하며 피예선은 조타를 하지 아니한다.

The study, "a semiotic analysis on 1930′s costume", is based on semiotic theory which analyze the meaning of signs. In the novels, "흙" and "삼대", character′s costume were used as a visual language that implies massages of character′s status, class, and the view of value. Analyzing the meaning of clothing signs, clothing could deliver the people′s informations to others and could be first things when people accept new value. The object of the studies are the novels, Hulk(흙) and Samdae(삼대) which are written by lee, Kwang-Soo and Yeom, Sang-Seob. In the novels, the social structure is classed as modern and traditional after we accept the western cultures and institutions. The traditional clothing, Han Bok, were dressed by the conservative woman. However, we could find the modernized woman dress with the western dress and the modified traditional style. According to the result of the research, we could find that clothing could be a sign which indicates value and also clothing is one of the first thing to change when people acquired new value.

1989년 배트맨(Batman), 2000년 엑스맨(X-man), 2002년 스파이더맨(Spider-man), 2003년 헐크(Hulk). 21세기 들어 매년 전세계 극장가는‘맨(Man)’의 바람으로 한차례 술렁인다. 이 영화들의 메인 캐릭터는 모두 인간보다 우월한 호모슈피리얼(homosuperial)들이다. 폭풍과도 같은‘맨’류 영화의 공통점은 무엇일까. 우선 미국의 만화 출판사의 양대 산맥인‘마블(Marvel)’과‘DC코믹스’의 스테디셀러라는 점이다. 둘째로 2004년의 시점에서도 끊임없이 후속 영화를 기획하고 연출한다는 점이고, 셋째로 게임시장에서 다양한 형태로 활용된다는 점을 들 수 있다. 그리고 마지막으로 캐릭터 상품으로 이어진다는 점이다. 원 소스 멀티 유즈(One Source Multi Use)를 최고의 가치로 여기는 21세기 문화시장에 있어서 이들은 그야말로 모범답안이요 보증수표라 할 만 하다. 이 모범답안을 적극 활용하기 위해서는 표면의 흥행요소뿐만 아니라, 심층의 이야기 확장 가능성을 짚어볼 필요가 있다.

This experiment has been made to find out the influence of soil bulk density on growth and root development of Populus alba ${\times}$ P. glandulosa in Buyeo-kun, Chungnam. Bulk density and porosity significantly change according to slope position and soil depth and have a significant effect on tree height, DBH, biomass, and the distribution of root development. The results extracted from the experiments are as follows; 1) Bulk density in average changes from $1.17g/cm^3$ (1.05 ~ 1.40) in lower slope position to $1.43g/cm^3$ (1.36 ~ 1.60) in upper slope position, and porosity from 52.65% (55.05 ~ 45.50) in lower slope position to 41.20% (43.81 ~ 37.21) in upper slope position. 2) Bulk density increases significantly with soil depth. 3) Tree height, DBH, and total biomass decrease with bulk density. 4) Foliage, branch, bolewood, bolebark, and root also significantly have a negative correlation with hulk density. 5) Populus alba ${\times}$ P. glandulosa has a shallow root system chiefly distributing only in AI horizon, and critical bulk density is $1.43g/cm^3$. Therefore, slope position, hulk density, and porosity are considered to influence on the growth, biomass, and root development of Populus alba ${\times}$ P. glandulosa.

Recently, the number of cloud web applications is increasing owing to the accelerated migration of enterprises and public sector information systems to the cloud. Traditional network attacks on cloud web applications are characterized by Denial of Service (DoS) attacks, which consume network resources with a large number of packets. However, HTTP DoS attacks, which consume application resources, are also increasing recently; as such, developing security technologies to prevent them is necessary. In particular, since low-bandwidth HTTP DoS attacks do not consume network resources, they are difficult to identify using traditional security solutions that monitor network metrics. In this paper, we propose a new detection model for detecting HTTP DoS attacks on cloud web applications by collecting the application metrics of web servers and learning them using machine learning. We collected 18 types of application metrics from an Apache web server and used five machine learning and two deep learning models to train the collected data. Further, we confirmed the superiority of the application metrics-based machine learning model by collecting and training 6 additional network metrics and comparing their performance with the proposed models. Among HTTP DoS attacks, we injected the RUDY and HULK attacks, which are low- and high-bandwidth attacks, respectively. As a result of detecting these two attacks using the proposed model, we found out that the F1 scores of the application metrics-based machine learning model were about 0.3 and 0.1 higher than that of the network metrics-based model, respectively.

One of the exciting research areas of the X-ray microscope is the observation of a living cell. In order to study a living cell with high resolution the order of the several tens nm, we need to improve the efficiency of mirrors which are components of an X-ray microscope system. In this paper we present the mirror design and manufacture to give a high resolution and reflectivity. We designed Wolter type I the condenser and objective mirror with the several tens of nm resolution. According to mirror design. we made the program using the visual basic. Using the new processing method as well as the ultra-precision diamond cutting, we directly processed the inside of an aluminum hulk in order to manufacture mirrors. From the experimental result, we think that the new processing method will improve a high reflectivity through the improved cutting tools and optimum cutting conditions.

The greenhouse hulk curing and drying system utilizing the direct solar energy was tested to see how much fuel could be saved for curing flue-cured tobacco at the Daegu Experiment Station, Korea Tobacco Research Institute (North latitute: 35$^{\circ}$49'), in 1979. The structure consists of transparent fiberglass exterior, polyurethan boards covered with galvanized iron as the heat absorbers and insulation boards, air duct in which the air is introduced to the furnace room of bulk curing barn, and gravel heat storage system. All exterior surface of heat absorbers, air duct, and gravels were coated with black paint. The air temperature and total radiation were 20.5 to 35.5$^{\circ}C$ and 1004.2 to 1436.2 cal/$\textrm{cm}^2$ during the 3 replicated curing tests, respectively. The greenhouse bulk curing and drying system was able to cut fuel consumption by 25 percent compared with the conventional bulk curing barn. The maximum temperatures for the top absorber and the inlet air of the system were 89$^{\circ}C$ and 64$^{\circ}C$, respectively, and the average temperature of inlet air was higher than that of conventional one by 18$^{\circ}C$.
