This study is a base research for the restoration of village landscape of the Namhan-Sansung. The Namhan-Sansung has been recognized as a top destination for dining places. However, there have been increasing concerns about the village landscape and its rich historic and cultural heritages transformed into dining places. The village landscape of Namhan-Sansung should be reconstructed as a setting for education and loaming of Korean history and culture forgotten for a long time. The landscape also should be a space where resolute resistance and spirit of Korean people and a futuristic village space where environment friendly community environment harmonizes with daily lives. Restoration efforts of village landscape of the Namhan-Sansung can get to start from exploring the prototype of the village. In order to restore the prototype, it is important to review potential elements and setbacks. Based on the prototype of the Namhan-Sansung village, transitions of village landscape were reviewed and directions of restoration were proposed. Also, an improvement plan was proposed after reviewing problems in system and planning.

The concept of Eco-city is to protect the city against development, trash, and industrialization. But the sprawl phenomenon of urbanization and industrialization are accompanied by the environment destruction. Therefore the importance and definition of eco-city were suggested. And to restore the urban ecological network, the prototype direction of eco-city at YongJeonDong in DaejeonCity were suggested in this study. It is believed that how to create an eco-city is an artificially developed $\square\square$Yong-Jun Dong$\square\square$ is a pending issue we are faced with situation. Herein lies the necessity of natural environment restoration and creation based on the so-called the Third Ecology

This study aims to analyze restoration techniques of traditional garden sites targeted Korean, Chinese, Japanese palace garden. Restoration was divided into the restore foundation and restore individual elements depending on the residual state of the actual garden features. And derived characteristics that should be considered by conservation techniques. The results are as follows; First, the Wanfo Pavilion Area in Beihai Park where the foundation and foundation stones were restored based on the relevant literature and comparative analysis. The Archaeological Site in Gwanbuk-ri, Buyeo restored only the remaining structures of the ponds, waterways and large buildings among the areas where the excavation was completed. The Second Daigokuden Garden in Heijokyo Palace restored building sites and foundation, and installed poles and piles so that the area of the Second Daigokuden Garden could be known. Second, Donggung Palace and Wolji Pond, Gyeongju where the restoration of individual elements was made, preemptively restored the remains of traditional gardens based on pond garden estuaries and feedbacks that were confirmed through initial excavation. Huanghuazhen Area in Yuanmingyuan Garden was restored based on Western copper plate prints and related records, but further data found after the restoration confirmed that it was restored differently than it is now. East Palace Garden in Heijokyo Palace covered existing features with soil and restored buildings on them. Typical garden elements such as landscape stone and waterways were preserved and exposed. Third, foundation restore is a case in which the base is identified through the current state of the traditional garden site, it is important to restore the foundation first and secure the territoriality when there is no restoration plan for the elevation structure or size of the garden relics. Restoration of individual garden elements requires careful examination of the literature by limiting the restoration of objects that can be restored through the examination of the literature for each element, such as some buildings or facilities in the traditional garden site.

In this paper, a FRAM design style based on PMOS-gating cell structure is described. The memory cell consists of a PMOS access transistor and a ferroelectric capacitor. Its plate is grounded. The proposed scheme employs three novel operating methods: 1) $V_{DD}$ precharged bitline, 2) negative-voltage wordline technique and 3) negative-pulse restore, Because this configuration doesn`t need the on-pitch plate control circuitry, it is effective in realizing cost-effective chip sizes. Implementation for a 2.5-V, 1-Mb FRAM prototype design in a $0.25-{\mu}m$, triple-well technology shows a chip size of $3.22\;mm^{2}$, an access time of 48 ns and an active current of 11 mA. The cell efficiency is 62.52 $\%$. It has gained approximately $20\;\%$ improvement in the cell array efficiency over the conventional plate-driven FRAM scheme.

Distressed structures require necessary remedial measures in order to restore their original structural properties like strength and stiffness. Validating the effectiveness of the proposed qualitative remedial measure experimentally is of utmost importance as there is no well-established analytical method to verify the effectiveness of the same quantitatively. Prototype testing which would have been the best option for this purpose would not only prove costly but also be associated with numerous practical difficulties; hence model testing is resorted as the only option for the purpose. This paper presents one such typical experimental study on the structural behavior of a distressed bridge, mainly observed in the form of prominent tilt in the bearing plate in transverse and longitudinal direction on downstream side. The main focus of the proposed experimental investigation is to assess the structural behavior particularly the load carrying capacity. The extent of deformation of some models with specific structural arrangements and some models with specific need based remedial measures were also studied. This study also assessed the contribution of each remedial measure towards restoration individually and collectively.

This study aims to understand the characteristics of dangsan forests and rural community forests (RCF), and seek for a landscape management scheme. Dangsan forests and RCF have been maintained by local residents since hundreds of years ago. However, many of them have been disturbed. The case sites were derived from the twenty villages previous investigated where dangsan forests and RCF's remainrd. The two sites were remodelled to restore what have been degraded. Hanbam village has maintained its dangsan forest with good management practices, whereas the dangsan forest and RCF of Goiran village showed relatively poor management. The size of dangsan forest at hanbam village was 13,784$m^2$, and major tree species was Pinus densiflora. In total, 151 trees with more than 30cm in DBH were standing on the site. As a cultural activity, the dangsan festival have been held in January $5^{th}$ by lunar calendar to the 2005 at the Jindongdan, a dangsan tree made of stone. The RCF of Hanbam village has disappeared due to the event of landslide in 1930, which needs to be restored. Goiran village has a dangsan forest and a RCF. The forests in Goiran village revealed many problems due to bad management practice. The prototype of the dangsan forest was deteriorated by introduced Prunus serrulata and the facilities for physical training. A systematic management scheme for dangsan forests and RCF's should be established with a close partnership among local residents, experts, and local government.

To restore visual sensation of blind patients, we have proposed a fully implantable retinal prosthesis comprising an three dimensionally (3D) stacked retinal chip for transforming optical signal to electrical signal, a flexible cable with stimulus electrode array for stimulating retina cells, and coupling coils for power transmission. The 3D stacked retinal chip is consisted of several LSI chips such as photodetector, signal processing circuit, and stimulus current generator. They are vertically stacked and electrically connected using 3D integration technology. Our retinal prosthesis has a small size and lightweight with high resolution, therefore it could increase the patients` quality of life (QOL). For realizing the fully implantable retinal prosthesis, we developed a retinal prosthesis module comprising a retinal prosthesis chip and a flexible cable with stimulus electrode array for generating optimal stimulus current. In this study, we used a 2D retinal chip as a prototype retinal prosthesis chip. We fabricated the polymide-based flexible cable of $20{\mu}m$ thickness where 16 channels Pt stimulus electrode array was formed in the cable. Pt electrode has an impedance of $9.9k{\Omega}$ at 400Hz frequency. The retinal prosthesis chip was mounted on the flexible cable by an epoxy and electrically connected by Au wire. The retinal prosthesis chip was cappted by a silicone to pretect from corrosive environments in an eyeball. Then, the fabricated retinal prosthesis module was implanted into an eyeball of a rabbit. We successfully recorded electrically evoked potential (EEP) elicited from the rabbit brain by the current stimulation supplied from the implanted retinal prosthesis module. EEP amplitude was increased linearly with illumination intensity and irradiation time of incident light. The retinal prosthesis chip was well functioned after implanting into the eyeball of the rabbit.
