The freshwater goby, Micropercops swinhonis ($G\"{u}nther$) was studied on the spawning behavior and egg develeopment at the two areas of Chollabukdo, Korea from March to May 1995. Egg mass attached to a layer under stones and the inner wall of waterplant, Cyperus. Spawning behavior was divided in to 1) premating stage: selecting spawning sites and formation of territory by male, 2) mating stage: enticement with zigzag-like dance and intermittant shaking of head by male and fertilization, 3) postmating stage: fanning, guarding and cleaning the nest by male. The eggs were transparent and spherical in shape, measuring $0.9\times1.4mm$ with yellowish yolk sac and many oil globules. Hatching began in about ten days after fertilization at water temperature $16~20^{\circ}C$. The newly hatched larvae were 3.8~4.0 mm in total length with 30 myomeres and their mouths and anuses were opened. Melanophores appeared at the air-bladder and the ventral side of caudal region.gion.

The purpose of this study is to develop a virtual office design in a 3D digital environment which involves a consideration of what people do and need in a virtual workplace and then translating that into a virtual environment for collaborative design. Areas in a virtual design office are defined according to different uses or activities in a physical office. The workplace includes a hall and information desk, working area, a conference room, a library, an entertainment room and a management room. It is important to define areas considering shared territory and personal territory. Communication and collaboration amonge designers are provided over the World Wide Web.

The size of song repertoires mainly provides evidence for explaining sexual selection for female choice as well as male-male competition. We investigated the role of oriental great reed warbler songs (Acrocephalus orientalis) of breeding territorial males. Early arrived males possessed larger song repertoires, paired earlier, and tended to become polygynous. No correlation was found between arrival date and territory size, but polygynous males significantly occupied larger territories than non polygynous males. Song sharing was low among males and the degree of similarity did not relate with spatial distance. Our results suggest that song repertoire of the oriental great reed warbler males play a role in female choice, where territory quality may affect male pairing success.

This study focused on the checking of design guideline using concept of reference plane as a promoting tool in order to apply to practical affair in relation to material standardization in housing build. For this purpose, we above all defined the role of reference plane. After establishing structural type can correspond to planning module of building components and coordination condition, we did exemplicated the sub-detail of building components which be to detach according to design method using the concept of reference plane that be complexed with spacial territory and replace cycle of building component or material.

Airport express line between InCheon international airport and KimPo has been started in April 2007. It has two kinds of train that are divided into commuter train and express. In this paper, we analysis the experimental results of the interior noise for both trains, as inside structure and materials of these trains are designed differently. It shows that the interior noise level of commuter train is higher about 10 dB(A) than express in open territory, and it in tunnel and viaduct increase by 7$\sim$12dB(A) compared with open territory. Also, we know that the door in the gangway is effective in protecting the rolling noise transmitted between carbodys from the outside.

It has been suggested that chromatin is organized into the stable structures that provide fundamental units of chromosome architecture in interphase mammalian cells. The stable structures of chromatin can be visualized as replication foci when replicating DNA is labeled with thymidine analogs. Previously, we showed that the chromosome territory expanded after BAF53 knockdown. In this study, we found that BAF53 is required for the formation of replication foci. DNA replication was not impaired in BAF53 knockdown cells, suggesting that the decrease in the number of replication foci is due to disintegration of replication foci, but not suppression of DNA replication. The attractive forces that maintain structural integrity of replication foci could be disrupted by BAF53 knockdown, and it may be responsible, at least in part, for the expansion of chromosome territories after BAF53 knockdown.

The general aim of this article is to explicate what can be researched in our field based on the new understanding on the ability of human visual intelligence. To follow this aim, three key discussions were followed. The first is to explain why the human visual intelligence research is so important in our field and how it was neglected. The basic orientations of the research questions used in its framing and in answering are reviewed. After reviewing traditional research orientations, as the second discussion, alternative, more useful perspective for thinking about human visual intelligence is suggested. And the possibility of contribution for the future research in general is discussed. In doing so, human visual intelligence was defined in rather practically oriented ways rather than theoretically oriented ones. More practical perspectives were suggested. The third discussion is to show how to use the alternative perspectives of human visual intelligence in the areas of educational technology research. It was hoped that the article lays out conceptual groundwork for generation of educational technology research frameworks which can be used for the research conduct, reproduction and sharing by adopting practically oriented views on human visual intelligence as a new territory of educational technology research.

Efficiency and universality which was the spirit of the modern age, had also an enfluence on our living environment. Various types of individual housing unit were developed and mass-produced. However, the exterior space in our city is a place for our social life and intermediate place to connect the private life of each individual to our society. For the people to adapt themselves well to their environment, it should be well organized which means it is clearly divided and integrated in a hierarchical order. To realize these conditions, adequate boundaries to divide each territory and entrances to connect each territory are two essential elements. One of the possible methods to realize these conditions can be found in korean traditional architecture where the exterior space has the same figural quality like buildings and is the center of the whole composition. Buildings, walls and colonnades are the elements to define space. Gates, pavilions, gabs between buildings and posts are the elements to symbolize the entrance connecting each space. Each exterior space is integrated to a whole composition. One is the gradual differentiation along the axis which is unique in korean traditional architecture. The other is the rectangular connection which is also found in the other area in the world. The results of this thesis are as follows. The exterior space in the housing area should have the figural quality. The elements to make boundaries defining exterior space are classified into horizontal elements such as low buildings and walls, and vertical elements such as tower-shape buildings which define space in a different way. The position of openings in a housing block affects the characteristic and openness of a exterior space. Various types of gates are used to decide the relationship between spaces.

1. 말뚝망둥어 (Periophthalmus cantonensis)의 포복도약하는 생활군의 생태를 구명하는 일환으로 1978년 7월에서 8월까지 금강을 중심으로 하기의 생활양식을 조사한바 다음과 같은 결과를 얻었다. 1. 분포는 칠산리(St. 1)에서 오식도(St. 7) 까지의 약 25km 연안선이다. 2. 서식밀도는 평균 1.5미/$m^2$이고 고조아대에서 평균 2.6미/$m^2(56\%)$, 중조아대에서 평균 1.5미/$m^2(32\%)$ 저조아대에서 평균 0.5미/$m^2(12\%)$였다. 3. 정주세력비는 : $86\%$이며 정주세력의 평균체장은 57mm, 생활권은 10m, 보행속도는 2.16mm/sec였다. 4. 말뚝망둥어는 성장함에 따라 분리, 독립하여 일정구역을 점령확보하며, 또 이를 확인시켜가는 경향이 있다. 5. 독립생활을 하던 것이 다시 모여 군집을 형성하는 경우는 특히 정주세력이 강한 고조아대에서 볼 수 있었으나 이들 단위군집내에서는 체장차이를 볼 수 없었다.
