The purpose of this study is to suggest optimum level of the Ratio of Greenery within the frame of vision in the interior landscape design through the analysis of visual character and preference of the interior landscape. The concept of the RG was defined as the ratio of projected area of plants higher than 1.2M against background wall from eye level. 5 photography of Interior landscape space -- 10,20,30,40 and 50% of the RG-- were constructed by computer graphic techinques. Likert scale and semantic differential scale were used to analyse visual character and preference of the interior landscape space. The analysis results are as follows : 1. Factors that compose of the image of the interior landscape have been found to be the "evaluation ", "complexity". The mean value of semantic differential scale showed a significant difference according to RG. When the RG was 20~30%, "Harmony" and "stability" was strongly recognized than the other factors and the interior landscape made the interior space natural and intimate. But at the RG 40!50%, users felt "stuffy" and "too complex" by many plants, so it was not efficient the Interior Landscape. 2. The visual preference was significantly different according to RG. The mean value of the visual preference was increased as the RG was higher, it was the highest at the RG 30%. But over the RG 30%, the preference level was declined. 3. Based on these results, this study suggests that the optimum level of RG in the Interior Landscape is 30%.at the optimum level of RG in the Interior Landscape is 30%.

Recently, for the purpose of constructing artificial ecosystem, the public aquarium and experimental mesocosm systems are receiving attention. To design and establish an aquarium and mesocosm system, there is need of several materials for simulating the environment, such as sediments, rocks, and plants. Expecially for sessile mollusks, there must be proper materials to which sessile invertebrates can adhere. Nowadays, many aquariums and mesocosm systems are using dead coral skeletons for sessile mollusks. This study was proceeded to have data on the effect of dead coral skeletons on water qualities with the experiment on the environmental factors. For this purpose, I made glass tank for experiment, chose two types of dead coral skeletons imported from the Indonesia and observed the change of water qualities and decomposition efficiency of TAN (total ammonia-nitrogen), nitrite (NO2-) and nitrate (NO3-). As a result, the lager the surface area was, the more TAN, nitrite and nitrate decomposition rate increased. In addition, coral skeletons covered with crustose algae and bacteria in the tank showed faster TAN, nitrite and nitrate removal rate and stabilization. Accordingly, this experiment suggested that dead coral skeletons could be used as a sub filter for the closed system as well as an adhering plate 폐쇄 사육 시스템에서 고착성 무척추동물 특히 연체동물의부착용 재료로서 이용되고 있는 dead rock과 live rock이 수질에 부가적으로 미치는 영향을 파악하고자 인도네시아로부터수입된 dead rock과 live rock을 인공해수를 이용한 실험수조에 투입 한 후 수질변화를 관찰하였다. 두 종류의 rock들은모두 pH 안정에 영향을 주었으며 질소화합물의 분해에도 일정한 영향을 주는 것으로 나타났다. dead rock의 경우 사용전 충분한 안정화 기간을 거침으로써 부착용 도구로서 뿐만 아니라 훌륭한 보조여과 기능을 담당할 수 있는 것으로 사료된다. live rock의 경우에는 이미 부착되어 서식하고 있는 조류나 박테리아에 의해 dead rock에 비해 더욱 높은 질소화합물분해 능력을 나타냈으며 초기 투입 시 부착되어 있는 생물의폐사나 해적생물의 유입에 따른 위험성을 제거 할 경우 사육시 스템 내에서 단순한 부착용 재료로서 뿐만 아니라 다양한 목적에 이용가능 할 것으로 사료된다.

As the internet becomes widespread and wireless communications technology rapidly develops, the paradigm in the communications market is changing from wired/voiced to wireless/data services. Wireless internet industry has a lot of potential growth because it is based on portable communications and the internet both, yet the industry has some constraints like this : the need of computer and internet connection all the time. So, mobile service using cell phones(PCS) and PDA is a kind of good solutions, but it is so difficult to make a plan for blocking virus such as Timofonica, BAT/119, and Liberty. This paper suggests the virus detection system designed for the mobile environment, especially concerning 'Timofonica' which sent SMS letter messages to the mobile devices through the PCs. This system is to detect viruses for the PCs planned virus detection system for the PCs, detect viruses on the mobile area through the wireless devices and ActiveSync, and save virus information into the DB in the PCs. If the virus detection system for the PCs finds malicious action virus, it blocks viruses to the mobile devices. To block increasing viruses in the PCs, this system search for malicious action by making pattern DB for well-known viruses, based on the existing virus patterns, we define viruses action patterns as a finite automata in order to detect the similar virus action patterns. With the basis of this study, we need to develop further techniques to examine the suspicious viruses automatically to be malicious viruses. This basic detection system on the mobile environment can be applied to the automatic vulnernability patching system or to wireless firewall syste

The purpose of the study was to determine the effects of balance training with ‘TETRAX' system, a balance training and assessment tool, on balance and mobility in acute hemiplegic patients. Nineteen matched subjects were assigned randomly into either an experimental group or a control group. An experimental group with 10 subjects received balance training with ‘TETRAX’ exercise program and con vention떠 physical therapy interventions 5 times per week during 4 weeks. A control group wi th 9 sub jects received conventional physical therapy inteπentions 5 times per week during 4 weeks. Outcome measures were taken before and after 4 weeks of interventions using the Stroke Rehabilitation Assessment of Movement (STREAM), the Berg Balance Scale (BBS), gait speed, and the fall down index. Results indicated that both exercise groups improved significantly in STREAM, BBS, and gait Speed (p<.05). The experimental group had a little improvement than the control group. Both exercise groups did not show statistical significance in fall down index (p<.05). Following 4 weeks of ntervention, except gait speed there was no statistically significant difference between two groups. However, these findings suggest that conventional physical therapy interventions with visual feedback training could be effective on improving balance and mobility than conventional physical therapy alone in acute hemiplegic patients
