최근 여러 단체들이 일정한 공간 및 기간동안 인터넷만을 이용해 살아가는 서바이벌 게임을 실시하고 있다. 인터넷 서바이벌 게임의 의미 중 하나는 콘텐트 제공자들이 고객의 니즈를 파악하여 더 낳은 서비스를 제공하는데 있다. 이 글에서는 조선일보사와 넷츠고가 공동 주최한 '제1회 코리아 인터넷 서바이벌 게임'에 대한 구체적인 생존 행태를 살펴봄으로써 인터넷 활성화에 기여하고자 한다.

In an complicated battlefield environment, information from enemy's camp is an important factor in carrying out military operations. For obtaining this information, the number of UAVs that can be deployed to the mission without our forces' loss and at low cost is increasing. Because the mission environment has anti-aircraft weapons, mission space is needed for UAV to guarantee survivability without being killed. The concept of Configuration Space is used to define the mission space considering with range of weapons and detect range of UAV. UAV must visit whole given area to obtain the information and perform Coverage Path Planning for this. Based on threats to UAV and importance of information that will be obtained, area that UAV should visit first is defined. Grid Map is generated and mapping threat information to each grid for UAV path planning. On this study, coverage conditions and path planning procedures are presented based on the threat information on Grid Map, and mission space is expanded to improve detection efficiency. Finally, simulations are performed, and results are presented using the suggested UAV path planning method in this study.

The mission capability of tank depends on its survivability. The survivability is ability for protection and tolerance by damage from threats. To improve the survivability of tank, we need an effectiveness analysis for loss of components, and accomplish performance enhancement using the result of analysis. In this paper, we develop a survivability analysis system for tank based on the importance. The importance numerically represents weight of each component which consisting of whole tank, also the importance is basic method of quantitative survivability analysis. To do this, we assign weight values to each component of tank, compose a weight tree, apply the importance calculation equation, and analyze the survivability of tank. Also we develop the system that consists of component structuralization and weight value setting program and survivability analysis and visualization program, and evaluate the system using implemented 3D CAD models of components of tank. The developed system apply to arrangement components.

Design with crashworthiness concept has been emphasized for almost aircraft and motor vehicles. However, crashes accompanied serious injury and death have been continuously occurred, and will be occurred subsequently. What was worse, it is a well-known fact that there were a good many crashes classified as survivable accidents in which fatal injuries were reported. But we cannot say that fatal injuries were inevitable consequences of those crashes. If crashworthy design for seat, restraint systems, and cabin strength were adequate or right, survivability in a crash event could be maximized greatly. To substantiate the right crashworthiness, we must thoroughly understand the characteristics of human tolerance under abrupt acceleration change, and the cabin design should be combined with proper use of energy absorbing technologies that reduce accelerations experienced by the occupants. In this paper, the emphasis on the human tolerance under abrupt accelerations as well as the necessity of change in design requirements for crash environment will be stressed to widen the belt of consensus for the right crashworthy design.

This study was carried out to survey the usability of Vitex rotundifolia as an afforestation and landscaping plant on destroyed slopes, sandyhills of sea boards, and places in need of landscaping. The growth characteristics of seedlings and rooted cuttings of Vitex rotundifolia in soils of varying properties and water content ere studied. In three test soils, with a water content of 5% each, the survival rate was more than 70ole for seedlings and more than 40％ for rooted cuttings. This demonstrates that Vitex rotundifolia is a very strongly xeric tree species. The length of stem, the diameter of root stock, leaves, and the length of root increased in all the three types of soil as the quantity of soil water increased. The difference of the growth in response to the water content of the soil was most pronounced in the length of the stem. The growth of seedlings was most notable in the weathered granitic soil. The sea sand and the red silt loam came second and third, respectively. However, there was no major difference in the three test soils. Thus, Vitex rotundifolia appears well-suited to several soil properties and soil water quantities, which makes it very useful as an afforestation and landscaping plant in various sites.

A large volume of hatching jar was tested whether it is an effective to hatch fertilized eggs of Pacific cod. The volume of hatching jar did not show any significant differences in survival of the fertilized eggs; 48.3% for the jar of 15 L and 50.4% for that of 42 L. Survival rate of the fertilized eggs in a large volume of hatching jar ranged from 40.0 to 71.2%, which was higher than those of conventional small circular tank. A higher survival could be achieved even though stocking density of fertilized eggs was as high as 5,000 mL/jar. Consequently, the tested hatching jar allowed for incubation of a greater number of eggs with higher survival rate in a much smaller space. In addition, it reduces costs and manpower, and requires a relatively small amount of water per individual unit (6,700 mL/min), and provides a way to incubate multiple rearing groups in a quarantine environment.

This study was conducted under the judgement that there was a need to make several mentions by reference to studies about the spatial composition of the traditional village. The judgement was not about the dimension that there was a problem about the spatial composition of the existing village but that it would be effective to make a fresh reorganization of it in a little more detail. As a result, this study presented seven spaces in the spatial composition of the traditional village. It attempted to analyze it by dividing it into four spaces such as ① natural space, ② residential space and work space, ③ moving space and boundary space and ④ play space and ritual space to fit its basic nature. First of all, it made a pictorial presentation of the basic form of the spatial composition of the traditional farming village in the late Joseon Dynasty which was most general and whose form has been handed down up to the present. And it described the composition of each space accordingly. It was not intended for a specific village. So it presented the historical change, the behavior of the members surrounding the village and a difference according to the nature of the village, which were judged to be very important in explaining the items of the composition of each space. As a result, it was found that the spatial composition of the traditiona Korean village well embodied the framework of their life in terms of their view of nature, lifestyle and worldview. The view of nature acted on the spatial composition of the village as a whole and is well reflected in the natural space in particular. Their lifestyle is reflected in the residential space, farming space, moving space and play space, and their worldview is spcifically mirrored in the boundary space and ritual space. In particular, this study focused on how to take a look at the element of Feng-Shui in discussing the spatial composition of the village.

인간이 생존하기 위하여 필요한 것들 중에는 음식, 물, 산소 그리고 피신처를 들 수 있을 것이다. 미 우주항공국(The National Aeronautics and Space Administration (NASA))에서는 21세기에 인간을 화성에 보내고, 달과 화성에는 기지를 세워 사람이 살수 있도록 하고자한다. 화성까지의 왕복 소요 시간은 3년여 이상으로 이 기간동안 우주선 승무원들이 소비할 산소, 물 그리고 식량의 양은 방대한 양이며, 우주공간으로 쏘아 올리는데 많은 에너지가 필요하기 때문에, 경제적으로 재생산이 가능한 생명지원시스템을 고려하고 있다.

시간과 공간의 제약이 사라지고 지구촌이 하나의 세상으로 발전하고 있다. 정보가 힘이 되는 세상에 고객의 요구에 부흥하는 기업만이 살아 남을 수 있으며 고객의 성향 및 기호에 부흥하는 상품을 개발하고 철저한 원가 분석에 의한 과학적인 경영만이 기업의 생존을 보장하는 세상이 되었다. 이 글에서는 IMF 이후에 개방화의 물결 및 구조 조정이라는 거대한 파도를 맞은 금융권의 선진 분석시스템의 구축사례를 소개하고자 한다. 광주은행에서는 과학적 금융 기법을 습득하여 불필요한 낭비 요소를 줄이고자 하며, OFSA를 이용하여 위험관리시스템을 구축함으로써 내부 역량을 축적하고 새로운 도약의 발판을 마련하려 노력하고 있다.
