건축법이 올 정기국회에서 개정될 예정이다. 이를 위해 건설교통부는 지난 7월 10일 입법예고 하고 법제처 및 관계부처 협의를 진행중인 것으로 알려졌다. 입법예고 내용중 상업지역 공동주택에 대한 일조기준 폐지 및 건축물의 일조기준을 남쪽기준으로 변경, 허가기준 고시, 피난 및 내화 등의 건축기준을 설계기준으로 고시, 사전승인대상(21층이상 10㎡이상)을 시도에서 직접 허가가능토록 하는 등 절차와 기준에 대한 대폭적인 변경이 예상되고 있다. 그러나 무엇보다도 일반인의 관심을 끌었던 것은 일간신문에서 중점보도한 "용도변경이 자유로워져 건축물을 마음대로 사용할 수 있다"와 "건축인허가시 건축사확인으로 허가 가능한 대상이 확대된다"는 것이었다. 따라서 용도변경제도와 허가제도의 개정 내용과 이를 시행시 발생하는 문제점과 함께 개선방안, 선결되어야 할 문제와 관련, 병행해서 개정되어야 할 과제 등을 살펴보고 바람직한 제도개선 방향에 대해서도 제안해 본다.

Nowadays, technologies such as RFID, sensor network makes our life comfortable more and more. In this paper we propose a wearable computing system for blind and deaf person who can be easily out of sight from our technology. We are making a wearable computing system that is consisted of embedded board to processing data, ultrasonic sensors to get distance data and motors that make vibration as a signal to see the screen for a deaf person. This system offers environmental informations by text and voice. For example, distance data from a obstacle to a person are calculated by data compounding module using sensed ultrasonic reflection time. This data is converted to text or voice by main processing module, and are serviced to a handicapped person. Furthermore we will extend this system using a voice recognition module and text to voice convertor module to help communication among the blind and deaf persons.

Frequency resource efficiency is important in satellite communication systems. One of the causes of a waste of frequency resource is bad flatness. In the case, flatness of satellite Tx terminals would be worse by ACI and guard band. In order to overcome this problem, this paper proposes a technique for frequency response equalization in satellite Tx terminals. First of all, a general linear polynomial expression which meets least squares of representative measurement data is calculated to interpolate unmeasured data. And then flatness can be adjusted using the polynomial expression. Simulation results illustrate adjusted data have lower peak to peak and standard deviation than original data, and these show that flatness be improved.

Present condition of the Youngsan River pollution is serious. Concentrations of organic materials and nutrients are high and algal bloom takes place frequently. The pollution is mainly caused by domestic wastewater input from urban areas like Kwangju and Naju City. In this study, 6 times of water quality surveys were done for mainstream and tributaries. Delivery ratios of each tributaries are calculated with the water quality and flow data. With Arc/View GIS, sub-basin are divided and pollution loads are estimated. These data are used for water quality modeling. River quality improvement effects are analysed with 5 scenarios including process upgrade of present WWTPs and construction of new WWTPs. These scenarios are applied for the Youngsan River based on the 7Q10 and Q275. And total wastewater treatment cost in the basin is analysed for each scenario.

The purpose of this study is to analyze contents and process of rites about sacrificial rites related Royal Mausoleums in early Joseon Dynasty, and to conclude, to review the position of Royal Mausoleums in the whole National Rites System. The sacrificial rites related Royal Mausoleums started from building Royal Mausoleums of 8 persons-ancestors since King T'aejo's great-great-grandparents, in 1392, founding Joseon Dynasty. In 1408, King T'aejo had died and his Kŏnwŏnnŭng (健元陵) was builted in Yangju, Gyeonggi-do. Since then, after kings of many generations died, each of Royal Mausoleums was builted solemnlly. In the process of this, sacrificial rituals modified and supplemented, especially during the reign of king Sejong(1418~1450). After all, the sacrificial rites related Royal Mausoleums was settled in KukchoOryeūi(國朝五禮儀, Five State Rites) compiled during the reign of King Sŏngjong. In process of Institutionalization of sacrificial rituals, the argument between king and vassals about four-seasons' ancestral rites was properly or not was occurred. That was because the memorial times of Royal Mausoleums overlaped Chongmyo's and more important Chongmyo's ancestral rites was neglected. But four-seasons' ancestral rites of Royal Mausoleums was continued until 17th century. Sacrificial rites related Royal Mausoleums as royal personal rites had simple processes compared to sacrificial rites of Chongmyo, upper-graded formal ancestral rites, under National Rites system. Justifying to served his parents with devotion, the kings in early Joseon Dynasty went to Royal Mausoleums 2-3 times annually. During coming and going, he show off his presence as king in power to his subjects through magnificent guard of honor. On the one hand, he met his subjects directly and acceded to various petition. Above all things, The kings in early Joseon Dynasty emphasized his military power through military training, namely, hunting, disposition of troops, and so on.

The rapid growth and popularity of Twitter have been one of the most influential phenomena in the era of social network system and the mobile internet, which also opens up opportunities for new business strategies; in particular, PR and marketing area. This study analyzed use of Twitter in terms of user characteristics and message attributes. Actual field data from the Twitter for PR and Marketing of a representative Korean IT company (Company "K") was used for this analysis. Research findings show that overall corporate twitter users show passive attitude in retweet behavior. Also, users who have relatively small network size (less than 1,000) are more active in retweet than power twitterians that have big network size(over than 10,000). It is showed that the rate of retweet is higher in the order of recruiting, promotional event, IT information, and general PR message. In the conclusion section, practical implications based on the research finding are thoroughly discussed.

These experiments were made to investigate the characteristics of cocoon pupas. The proximate composition and fatty acids were analyzed. In order to eliminate the unfavorable odor of cocoon pupas, alkaline treatment and extraction of fat were conducted. The results were as follows. 1) The unfavorable odor can be eliminated through the extraction of fat. Boiling with n-hexane for 1 hour was the best. 2) The cocoon pupas were contaminated with $10^8$ bacterial counts/g at the first eating state. When they were stored at room temperature for 6 days, bacterial counts did not increase inure than $10^8$, but they were putrefacted with bad odor. 3) The powder of defatted cocoon pupas prepared for food material contained around 1.3% moisture, 76.0% protein, 0.8% crude fat, and 4.8% ash. 4) It was not efficient to eliminate unfavorable odor by alkaline treatment. 5) The fatty acids of cocoon pupas are composed of 0.35% myristic acid, 20.90% palmitic acid, 0.5% palmitoleic acid, 7.11% stearic acid, 32.20% oleic acid, 5.48% linoleic acid and 30.31% linolenic acid.

Occasionally, MODEM test in satellite communication systems are needed. But Rx terminals in satellite communications are designed to obtain high SNR generally, therefore artificial bad conditions and environments are demanded for the test. One of the typical method is satellite output power reduction. Using noise generator can be another method. However, these costs a lot of money, time, and procedures in reality. In order to overcome these problems, this paper proposes an artificial noise generation method for MODEM test in satellite communication systems. First of all, SNR of a general heterodyne Rx terminal is calculated. Based on the calculation, a new model which is including variable attenuator is proposed to increase noise level. Simulation results illustrate the variable attenuator can control SNR, and these show that MODEM test in satellite communication systems be possible.
