In order to solve housing shortage, an apartment has been built and supplied in large quantities in Korea. As such a result, the apartment became a typical housing type in Korea. However, the housing became vulnerable to accommodate rapidly changing life-style & life-cycle of koreans and was lost the concept of Korean traditional housing for inheriting and developing Korean traditional culture. Therefore, this paper aims at eliciting of design elements for development on standard model of long-life housing with durability & flexibility based on data derived from housing consumers's questionnaire survey and expert's opinion surveys. We expect that the standard model developed on the basis of open building applying support & infill elements will be used as a standard model for planning future long-life housing with capacity.

Most people with visual impairments can not use both hands freely because they carry a cane. And unnecessary contact with people around you during walking can occur. Other guides include guide dogs, but the price and maintenance cost are expensive and difficult to manage. In this paper, we propose a smart glove, which prevents unnecessary contact when blind people use the cane, detects the obstacle ahead by using the ultrasonic sensor, and informs the presence of the obstacle by using the servo motor. In addition, the electrostatic proximity touch module on the fingers executes a specific application of the smart phone connected by Bluetooth when the finger touches each other. It is designed to allow you to use text or phone calls when you are lost or in an emergency. The results of this study will be used as a tool to provide a more convenient life for the visually impaired.

Implant treatment has long been established as the main stream for the recovery of lost teeth. Implant therapy, which began to be practiced under the concept of osseointegration, was performed on the completely healed bone, but implant placement immediately after extraction, which began to be introduced in the 1970s, began to become a widely used treatment modality since the 2000s. However, as with all other procedures, immediate implant placement is not omnipotent. If you are obsessed with the obsession that you need to provide quicker implant treatment to the patients, and if you do it as if you are being chased by time, it is the immediate implant placement that can lead to various embarrassing situations. In this article, to reduce complications, the author will look at some issues that need to be considered when placing implants immediately after extraction.

Lately, a large amount of textual data have been poured out of the Internet and the technology to refine them is needed. Most of these data are long text and often have no title. Therefore, in this paper, we propose a technique to combine the sequence-to-sequence model of RNN and the REINFORCE algorithm to generate the title of the long text automatically. In addition, the TextRank algorithm was applied to extract a summarized text to minimize information loss in order to protect the shortcomings of the sequence-to-sequence model in which an information is lost when long texts are used. Through the experiment, the techniques proposed in this study are shown to be superior to the existing ones.

To shed light on the genetic differences among food-originated coagulase-negative Staphylococcus (CNS), we performed pan-genome analysis of five species: Staphylococcus carnosus (two strains), Staphylococcus equorum (two strains), Staphylococcus succinus (three strains), Staphylococcus xylosus (two strains), and Staphylococcus saprophyticus (one strain). The pan-genome size increases with each new strain and currently holds about 4,500 genes from 10 genomes. Specific genes were shown to be strain dependent but not species dependent. Most specific genes were of unknown function or encoded restriction-modification enzymes, transposases, or prophages. Our results indicate that unique genes have been acquired or lost by convergent evolution within individual strains.

Penicillium purpurogenum , which produces a copra galactomannan degrading enzyme extracellularyl, was isolated from soil , and its properties and formation condition of mannooligosaccharides were investigated. The optimum ph and temperature for the activity of the mannanase were 5.5 and 55$^{\circ}C$, respectively. The mannanase was stable in between pH 3.5 and 7.0 after 2 hr incubation at 3$0^{\circ}C$ lost 90% of the original activity after incubation at 55$\AA$ and pH 5.5 for 2 hr. With two different substrate concentration, hydrolysis of white coprameal proceeded rapidly at the early stage of the reaction, but gradually solwed thereafter especially at a higher concentration of copra meal (20 %). The enzyme hydrolyzed white copra meal to monosaccharides, mannobiose and mannotriose at the final stage of the reaction.

The present study aims to document the run-up height, losses of human lives and property damage due to the tsunami occurred on December 26, 2004 in Andaman and Nicobar Islands, India. These Islands were severely devastated by the tsunami. Approximately 1,925 people were lost their lives and 5,555 people were reported missing. A field survey carried out at 26 locations indicates that the passenger jetty of Little Andaman area recorded the highest run-up height of 17.3m and the Chidiyatopu area had the greatest inundation of 500m from the coastline.

A new modular Lateral Information Propagation Networks(LIPN) has been designed. The LIPN has shown to be useful for reconstruction of information[3]. The problem is the fact that only the small number of nodes can be implemented in a IC chip with the circuit VLSI technology. The proposed modular architecture is propagated the neural network through inter module connections. For such inter module connections, the host (computer or logic) mediates the exchange of information among modules. Also border nodes in each module have capacitors for temporarily retaining the information from outer modules. The LIPN with $4{\times}4$ modules has been designed and simulation of interpolation with the designed LIPN has been done.

Stream Control Transmission Protocol (SCTP) uses the 32-bit checksum in the common header, by which a corrupted SCTP packet will be regarded as a lost packet and then discarded. This may result in degradation of SCTP's throughput performance over wireless networks. This paper proposes a new chunk checksum scheme for SCTP, in which each data chunk contains its own checksum field and SACK chunk carry corresponding Transmission Sequence Number (TSN) with timestamp for every corruption event. The proposed chunk checksum scheme is introduced with the following three purposes: 1) to distinguish the chunk corruptions from the chunk losses; 2) to avoid the unnecessary halving of the congestion window (cwnd) in the case of chunk corruption; 3) to avoid the unwanted timeouts which can be induced in conventional SCTP in the case that the retransmitted data chunks are corrupted again in wireless networks. Simulation results show that the proposed chunk checksum scheme could improve the SCTP throughput in the wireless environments with a high bit error rate.

In 1997, Yongsan-gu Office of Seoul held a design competition for 'Hyochang Park as a holy Grounds'. Although various shrines and monuments were located in it, Hyochang Park had lost its sense of pace as a 'holy grounds' mostly by its neighborhood-park-like atmosphere at its entrance area. Specific requirement for this competition was designing a 'symbolic object' to make this park more 'holy grounds' looking. However, it was very regretable that Yongsan-gu Office did emphasized on the 'object' rather than on the space or place in this design competition. Three points were emphasized in the winning scheme proposed by the author: where the object be located in the park, how the object be connected with the rest of the park, and how the object harmonized with some of traditional looking architectures and shrines. The purpose of this paper is to articulate the concept of the winning entry in detail and to describe how the concept actualized in reality.
