Mating behaviour of the gammarid amphipod, Hyale rubra, was observed. H. rubra displayed precopulatory mate guarding: males clasped females with their gnathopods during copulation, forming a pair. Males also participated in embryo care during the incubation period. The population was small, and the sex ratio was almost equal. Energy allocation for mating effort and parental effort in the two sexes appear to be almost equal. The mating system was sequentially polygamous (or promiscuous) and there was conspicuous sexual dimorphism in the size of the gnathopod, which was used for mate guarding. However, there appears to be relatively weak sexual competition for mating opportunities despite conspicuous sexual dimorphism. H. rubra did not display territorial competition or external fertilization. Nevertheless, the male provided paternal care. Since H. rubra inhabit tide pools and live on algae, the polygamous mating system of the species can be explained by the polygyny threshold model. The evolution of mate guarding and parental care may have been favored by the species' low population density and harsh environments, an interpretation consistent with the optimality model.

According to the passage of an age, a method which communicates each other between the city and space, and space and a human has changed. Recently, as the city is developing related with the public, the sphere and a territory of activity of a public has been wider in an environment of the city. Therefore, development of night scenery and the rise of a medium of a vision are accompanied with a new material and the high-technology. Innovation of abundant techniques tends to being surface and mass media, and breaks from the architectural aspect of space as mutual expansion of relations between interior and exterior, and making a boundary obscurely. Space design represents peculiarity of non-territorial which modern art, an advertisement, a media and a reflection are integrated as getting over above tendency. As we find out methods which the public can communicate with the space in wider territory, the public and the space can extend mutual relations and the design of modern space is been varying a part as the space which has a context of city and synthetic sociality for the public by avoiding independent objects.

The purpose of this study is to explain innovative changes of men's fashion in 'a cyber society', which has come with the advent of internet revolution and where we have witnessed social changes in view of sex, race and class. As for the research methodology, literary research was under taken to study characteristics of cyber society. And demonstrative studies on men's fashion were undertaken through the analysis of photos. 'Cyber space' is defined as 'a communication network of informations and opinions' or 'pseudo world created by computer technology'. Our current world, which has continuous interaction with cyber space, can be understand as cyber society. In a cyber society, transcendental structure is not accepted, feminine characteristics appear more frequently, and western-biased territorial features lose its ground. These characteristics are rooted in ideological characteristics of cyber society, such as opposition and composition. Considering the characteristics of cyber society, the aesthetic images of men's fashion in cyber society can be explained with de-authoritarianism, 　metrosexualism and multi-culturalism.

The purpose of this study is to clarify the actual conditions of layout type and territorial area of middle schools. This article discuses about the characteristics of the floor plan composition and the layout type of 30 middle schools in gyeongnam province. The results of this study are summarized as follows; 1) In facilities arrangement of middle schools, it shows diverse forms of arrangement from existing uniform straight type, however, most of schools do not being against the simple in their external space. Therefore, it requires an expansion of space size and facilities for the change of school life outside class. 2) Comparing to traditional middle school facilities, it occurs various types of plane and the area is somewhat expanded in the school with same class size, however, it needs to improve facility standards in its reality to deal with the change of future educational environment actively.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on the Earth Observing System (EOS) of Terra and Aqua satellites, launched in December 1999 and May 2002, has been directly received by Korea Aerospace Research Institute (KARI) ground station facility from July 2002. MODIS scans a swath width of 2330 km that is sufficiently wide to cover Korean peninsular, Yellow and East Sea at once. The MODIS has 36 spectral bands between 0.415 $\mu\textrm{m}$ and 14.235 $\mu\textrm{m}$, i.e., through the visible into the thermal infrared. MODIS has been observed active fires, floods, smoke transport, dust storms, severe storms since February of 2000. The satellite imagery obtained through the MODIS will be utilized for many application such as national territorial management, agriculture, natural environment, atmosphere and ocean, etc. In this study is to introduce various application field of MODIS imagery and data processing system.

본 연구는 지역전략산업진흥사업의 효과를 통하여 향후 분권적 상향적 지역산업정책이 다양한 형태로 발전하여 지역의 자생적 능력을 향상시키고 지역의 혁신능력을 배양하여 지역산업을 진흥시키고 지역경제를 활성화 한다는 측면에서 접근하였다. 지역산업의 진흥은 현 정부의 광역경제권 구축정책의 기본전제로 광역을 이루는 한 축의 발전이 타 지역에 비하여 낙후된다면 광역이라는 경제권구상에 있어 실패 또는 갈등요인으로 작용할 수 있을 것이다. 분석결과, 충북지역의 전략산업은 타 지역과 비교하여 상대적으로 빠른 발전을 하였고 지역의 전략산업발전 정책이 효과를 극대화하기 위해서는 R&D체계의 효과적인 개선이 필요함을 도출하였다.

The theory of terrestrial impact which has been developed by the astronomy scientists since 1970s is employed for this article in a new angle that atmospheric conditions of our planet should be adopted in the interpretation of the history of mankind. Large and small terrestrial impacts must be acknowledged as key tasks in terms of the study of 'world history'. The Society of Interdisciplinary Studies has already advocated that the 'Bronze Age Civilization' was strongly influenced by the long term terrestrial impact phenomena. Based on historical materials from Korea, the present study was able to identify the years 680-880, 1100-1220, 1340-1420, and 1490-1760 as periods in which territorial impacts occurred.

The territorial air that our sovereignty is being applied to is divided into several zones and areas. In order to use and manage them effectively, these zones and areas have laws, regulations and rules. The number of airspaces (MOA : Military Operation Area) and Ranges that are used in the military are limited and many airbases are being used for training. Currently the central department manages some, and the rest are independent airbases. Therefore, efficient allocation is not performed and the result occurs where airspaces and ranges are allocated unnecessarily. This is increasing the workload of staff leading to unnecessary re-work. To slove problem, this study proposed models for allocating airspaces and ranges using goal programming with multi-objective functions of minimizing the deviations of the target values.

Changing of paradigm at 21Century is changing a part of routine lives and it affects speculation system of recognizing the world. In this society, human is demanded changing of a part and new learning continuously. Like this, a role of individual and a part of various lives by changing of social environment have a close connection each other. In this society, they would need new circumstance of space by method of work. However, what show not necessity improving of work space but changing is the realities of our society. This thesis examine non-territorialization characteristics by focusing on the openness, composition, and flexibility. The working space on 21c head for a non-territorialization and be summarize. decenterial arrangement, increasing of public space and unification of personal work-station. The purpose of this study is to examine the non-territorialization by analysis of 21c working space.

Since specific types and physical characteristics of anuran calls can represent reproductive qualities of a calling male, anuran calls have been studied in context of mate choice. We in here report call types of Rana dybowskii and their variations from two different recording sites. Calls of R. dybowskii are classified to three types based on their physical characteristics and behavioral observations; 'A-call'functions to advertise locations of a calling male and to attract potential mates. A territorial male emits 'B-call'only during male-male interaction. 'C -call'is released when a male frog was clasped by another male. The A-call from two recording sites, Miwon and Wonju, shows high variations in their call characteristics.
