When it comes to discussing the natural behaviors of human life, defining the word "community" itself can be extremely crucial. The word "Community" can be defined as a group of interacting human beings sharing an environment. It is also the basic form for "dwelling" which can be explained as a quint essential factor in human life. Compared to the previous traditional society with strong bonding and close chemistry between neighbors, modern society with simple and monolithic apartments brought a literal extinction of what has been called as a 'relationship'. Hence, people started to take this phenomenon as a problematic issue. Also, high-rise apartments made its residents more isolated and individualistic on a growing basis. In order to aid the aggravating symptoms, there has been a wide recognition between the "dwellers" to develop and strengthen their "community". This movement in strengthening the "community" is currently on a full expansion towards the cyber space, riding the tides of a drastic improvement of the Internet. Apartment web sites today not only displays introductory level of information they also provide wider meanings of general lifestyle plus deeper content, which can enhance their community.

Phytoplasmas were discovered in diseased Elaeocarpus sylvestris trees growing on Jeju Island that showed symptoms of yellowing and darkening in the leaves. Leaf samples from 14 symptomatic plants in Jeju-si and Seogwipo-si were collected and phytoplasma 16S rRNA was successfully amplified by nested polymerase chain reaction using universal primers. The sequence analysis detected two phytoplasmas, which showed 99.5% identity to 'Candidatus Phytoplasma asteris' and 'Ca. P. malaysianum' affiliated to 16SrI and 16SrXXXII groups, respectively. Through polymerase chain reaction-restriction fragment length polymorphism (RFLP) analyses using the AfaI (RsaI) restriction enzyme, the presence of two phytoplasmas strains as well as cases of mixed infection of these strains was detected. In a virtual RFLP analysis with 17 restriction enzymes, the 16S rRNA sequence of the 'Ca. P. asteris' strain was found to match the pattern of the 16SrI-B subgroup. In addition, the phytoplasmas in the mixed-infection cases could be distinguished using specific primer sets. In conclusion, this study confirmed mixed infection of two phytoplasmas in one E. sylvestris plant, and also the presence of two phytoplasmas (of the 16SrI and 16SrXXXII groups) in Jeju Island (Republic of Korea).

Metabus, currently represented by Second Life on the Internet, is the next-generation 3DCG Internet world in which the 2D Internet world has evolved, and has grown as a new ICT culture of mankind that can replace real society with virtual society. As such, the reason why the world of metabus has rapidly expanded is that the era of 3D Internet has arrived due to the evolution of the Internet, which only used information, and the spread of 5G communication in user-participating WEB. However, there are many situations in which laws do not exist in this virtual world and various illegal acts occur. As the Internet culture developed earlier, illegal activities by users began to appear, and as the legal responsibility of Internet providers was discussed, mankind quickly passed the Millennium Copyright Act or introduced new copyright protection measures such as technical protection, transmission rights, and rights management information. Therefore, this paper reviews and studies how to accept and further grow this new metabus culture, including the viewpoint of intellectual property.

본 연구는 고령자의 삶의 만족도를 높이기 위해 가상현실(Virtual Reality: VR) 기기 및 콘텐츠를 활용하고 체험하는 것에 초점을 두었다. 여가 활동은 일자리가 없는 고령자의 주된 활동이다. 결과적으로, 여가 활동의 다양성과 질이 고령자의 삶의 만족도에 영향을 미친다. 동영상 콘텐츠를 포함한 가상현실 서비스는 고령자들에게 발전되고 흥미로운 경험들을 제공할 수 있다. 전세계에 걸쳐, 인구 고령화는 각 사회에서 가장 중요한 문제들 중 하나가 되었다. 고령화에 따른 사회적, 경제적 부담은 한국을 포함해 세계의 지속가능성에 심각한 도전이 되고 있다. 저자들은 고령 피험자(50세부터 90세까지)를 대상으로 VR의 사용을 연구한다. 본 실험에서 저자들은 시스템 품질, 인터페이스 품질, 현존감, 즐거움, 재이용 의도, 첨단과학기술 인식을 포함한 요인들을 연구하고 측정한다. 회귀분석에서 근접감(t=5.381, p<.01)과 선명감(t=4.494, p<.01)은 VR의 현존감에 유의미한 영향을 미치는 요인이다. VR의 현존감(설명 변수)은 즐거움(t-4.312, p<.01)과 재이용 의도(t=3.323, p<.01)에 유의미한 영향을 미친다. 그러므로 고령 피험자는 VR에서 현존감을 더 느낄수록, 더욱 높은 즐거움과 재이용 의도를 느낀다고 볼 수 있다. 결국, 새로운 과학기술에 익숙하지 않은 고령자도 가상현실 서비스를 이용해 여가 활동의 질을 개선할 수 있음을 시사한다.

In this paper, resonance durability analysis technique is presented for the fatigue life assessment considering dynamic effect of a vehicle system. In the resonance durability analysis, the frequency response and the dynamic load on frequency domain are used. Multi-body dynamic analysis, finite element analysis, and fatigue life prediction method are applied for the virtual durability assessment. To obtain the frequency response and the dynamic load, the computer simulations running over typical pothole and Belgian road are carried out by utilizing vehicle dynamic model. The durability estimations on the rear suspension system of the passenger car are performed by using the presented technique and compared with the quasi-static durability analysis. The study shows that the fatigue life considering resonant frequency of vehicle system can be effectively estimated in early design stage.

The perceptual change and reproduction process of a space is distinguished from the difference between the Modem Times and the digitalized Post-modem Times. According to this changing aspect, the dwelling. concept is also progressed toward the escapeness from the regularly standardized settlement. But, as written above, the escapable dwelling behavior pattern is re-territorizated through new restriction and domination system. Among the newly re-territorized dwelling areas, the virtual space that included human being's equal in the contemporary meaning has already been on the surface in our daily life, it has been enlarging into all kinds of activity. The virtual space has the possibility to extend beyond a already well-used to physical space and time unlimitedly. But, owing to the ambiguous boundary between the real space and the virtual space, it is getting more important to define the spatial substance in the Digital Age. From now on, especially, the academical fields like a Architecture and a Interior Design that dealed with a living space have to give it a great shot. What I really want to say is that various approach about the space itself with the help of many sorts of so-called a Case Study could be a diversity & uniqueness out of a typical point of view about the study handling on space and time.

As Internet services have spread centering on mobiles, diverse services used in everyday life have become mobile services. For humans, residential spaces have significant implications as physical and psychological environments. Therefore, being provided with accurate information on the room that must be sought to find out the residential space wanted by the user can be said to be an important element of real estate apps. However, when buying real estate, people prefer searching for information using mobiles and verifying the information by visiting the real estate firsthand due to increases in damage due to false offerings. This way approaches as inconvenience in cases where the buyer lives far away or if the conditions are not suitable. Therefore, in the present study, a 'room finding application using VR' was designed and implemented using virtual reality (VR) used for diverse purposes. VR is a technology that provides the user with the sense of presence as if the user is actually present in the space. It was used in the present study as a means to provide more accurate information. The use of the application designed and implemented in the present study is expected to reduce false offerings information at least slightly so that users can be provided with more accurate information on the real estate of interest.
