Ami-dong Crematorium in Busan was established as one of the public facilities in 1929(the period of Japanese Occupation). It is the originator of Busan Yeongnak-Park(永樂公園), the funeral facilities of Busan municipality. The crematorium of Busan region was accepted at an earlier stage inside Japanese Concession in accordance with the opening a port. As Ami-dong Crematorium was constructed as a public facilities, the precedent has been maintained so far, providing a background equipped with the leading public corporation facilities in Busan area. This study was based on the expansion construction document founded by National Archives in Korea. Above all things, this research revealed the establishment and change of Busan Ami-dong Crematorium as the historical point for the formation process of recent public funeral facilities.

We identified a gene encoding the N-acetylmuramoyl L-alanine amidase (amiB) of Vibrio anguillarum, which catalyzes the degradation of peptidoglycan in bacteria. The entire open reading frame (ORF) of the amiB gene was composed of 1,722 nucleotides and 573 amino acids. The deduced amino acid sequence of AmiB showed a modular structure with two main domains; an N-terminal region exhibiting an Ami domain and three highly conserved, continuously repeating LysM domains in the C-terminal portion. An amiB mutant was constructed by homologous recombination to study the biochemical function of the AmiB protein in V. anguillarum. Transmission electron microscopy (TEM) revealed morphological differences, and that the mutant strain formed trimeric and tetrameric unseparated cells, suggesting that this enzyme is involved in the separation of daughter cells after cell division. Furthermore, inactivation of the amiB gene resulted in a marked increase of sensitivity to oxidative stress and organic acids.

Smart grid is a network of computers and power infrastructure that monitor and manage energy usage efficiently. Recently, the smart grid demonstration projects around the world, including the United States, Europe, Japan, and the technology being developed. The protection of the many components of the grid against cyber-threats has always been critical, but the recent Smart grid has been threatened by a variety of cyber and physical attacks. We model and analyze advanced metering infrastructure(AMI) in smart grid. Using attack countermeasure tree(ACT) we show qualitative and probabilistic security analysis of AMI. We implement using SHARPE(Symbolic Hierarchical Automated Reliability and Performance Evaluator) tool and calculate probability, ROA, ROI, Structure Importance, Birnbaum Importance.

스마트미터링 혹은 스마트미터의 기본 요구사항 중 하나는 AMI 환경의 장비들에 대한 펌웨어 원격 업그레이드 기능이다. 수동적인 H/W 장비의 교체 없이 S/W 및 펌웨어 교체만으로 변화되는 환경에 유연하게 대체할 수 있도록 하며 다양한 부가서비스 창출 및 사업화지원을 위해서 시스템을 주기적으로 유지보수함으로써 유지보수에 필요한 인건비를 절감 한다는 측면과 서비스의 즉시성 측면에서 매우 중요하다. 본 논문에서는 AMI 시스템 개발 시작품 중 데이터수집장치 및 스마트 미터를 대상으로하는 원격 펌웨어 업그레이드시스템(FUMS, Firmware Upgrade Management System)의 국제적 수준의 일반적 요구기능과 시스템 설계 내용을 제시한다.

Objective: In this study, the analgesic effect of gold injection aqua-acupuncture on CFA induced arthritis in rats was inverstigated. Furthermore, to determine the antinociceptive mechanism of gold injection aqua-acupuncture, naloxone and yohimbine were administrated intraperitoneally 15min prior to the gold injection aqua-acupuncture. Methods: The experimental groups were divided into 6 groups. Control group, NSI, AMI, AMI+SL : AMI+Nx, AMI+Yb. Thereafter we measured the chages of TFL between control and experimental groups. Results: 1. The tail flick latency induced by CFA was significantly increased on AMI as compared with the NSI group. 2. Effect of sodium aurothiomalate aqua-acupuncture in TFL on CFA was decreased after application of naloxone. The anti-nociceptive effect of AMI was completely antagonized by naloxone(an opioid receptor antagonist). 3. Effect of sodium aurothiomalate aqua-acupuncture in TFL on CFA was decreased after application of yohimbine. The anti-nociceptive effect of AMI was completely antagonized by yohimbine(${\alpha}2$-adrenoceptor antagonist). Conclusions: According to the results, gold injection aqua-acupuncture has significant analgesic effects on adjuvant induced arthritis in rats and the effect of anti-nociception was mediated by opiodergic system and ${\alpha}2$-adrenergic system.

In order to increase energy efficiency, developments of the advanced metering infrastructure (AMI) in the smart grid technology have recently been actively conducted. An essential part of AMI is analyzing power consumption and forecasting consumption patterns. In this paper, we analyze the power consumption and summarized the data errors. Monthly power consumption patterns are also analyzed using the k-means clustering algorithm. Forecasting the consumption pattern by each household is difficult. Therefore, we first classify the data into 100 clusters and then predict the average of the next day as the daily average of the clusters based on the deep neural network. Using practically collected AMI data, we analyzed the data errors and could successfully conducted power forecasting based on a clustering technique.

This paper analyses the violation rate of CJK joint Chines character Unicode to the source code rule. In the paper, Chinese character 150ea in Chinese Unicode which have relatively a higher frequency in use of a character was chosen to study. The frequency rate in use of the 150ea characters is about 50% of the total frequency rate of the Chinese characters. The study was applied the AMI/HDB-3 line coding/scrambling and HDLC protocol, According to the analyses, the number of violated characters were 77ea of 150 ea, frequency rate in use 29%. Therefore, when the violated 77ea characters are replaced to the matched character codes to the source coding rule, the processing rate of the line coder can be improved about 37%.

Poria cocas has been reported to be effective in skin whitening. However, the direct effect of P. cocas ethanol extracts (PCEE) on melanin synthesis has not been scientifically studied. To elucidate the direct effect of PCEE on melanogenesis, a 3,4-dihydroxyindole-2-carboxylic acid (DOPA) synthesis assay, tyrosinase activity assay, and Western blotting for melanogenic proteins, including tyrosinase, tyrosinase-related protein (TRP)-1, and TRP-2 were performed in mouse B16F1 cells. The results revealed that PGEE inhibited melanin production in a dose-dependent manner by blocking the synthesis of DOPA. Although the activation of tyrosinase was not affected, the expression levels of TRP-1 and TRP-2 were controlled. These results suggest that PCEE has a whitening effect, indicating that it may be a useful agent in the development of whitening cosmetics.
