무선 인터넷 서비스를 위한 WiBro시스템의 효율적인 부하 제어 절차 제안 및 성능분석

김소형,김정호,Kim, So-Hyoung,Kim, Jeong-Ho 한국통신학회 2007 韓國通信學會論文誌 Vol.32 No.5A

In this paper, we propose the load control procedure for WiBro system in order to keep the data traffic throughput maximum. The transmitter at a mobile terminal can estimate maximum available power for each user and then the maximum number of subchannels can be calculated considering the total available power. The data traffic throughput and the total throughput (the sum of signaling traffic and data traffic throughput) are considered. As the number of bandwidth requests per frame increases, the data traffic throughput can significantly decrease. Therefore, the load control procedure is indispensible to maintain the data throughput at the maximum level. So, we propose the load control procedure to prevent data traffic throughput from decreasing and evaluate the proposed procedure through the computer simulation under the multi-user environment. The maximum throughput can be maintained by applying the proposed procedure. 본 논문에서는 WiBro 시스템의 특징을 바탕으로 데이터 트래픽의 수율을 최대로 유지 할 수 있도록 기존 방법을 개선한 부하 제어 방법을 제안하고 컴퓨터 시뮬레이션을 통하여 성능을 평가한다. 송신단에서 단위 사용자당 최대 할당 가능한 전력이 주어졌을 때, 송출 가능한 전력범위 내에서 최대의 수율을 갖도록 각 부반송파에 데이터 비트를 할당하는 알고리즘을 바탕으로 WiBro 시스템의 전체 수율(throughput)과 데이터 트래픽 관점에서 시스템의 수율을 고려하였다. 제안하는 방안의 평가를 위해 사용된 시스템의 파라메터로 WiBro시스템의 규격값들을 사용한다. 현재 시스템의 부하제어 절차로는 접속과다로 인한 대역폭 요구(bandwidth request)의 증가로 인하여 과부하 상태에 이를 때 시그널링 트래픽으로 인하여 데이터의 수율이 급격히 감소하며 접속지연이 매우 증가하게 된다. 이러한 현상을 막을 수 있는 부하 제어 방법을 제안하고 다중 사용자 환경에서 시뮬레이션을 통하여 평가한다.

메커니즘 관점에서 본 조직변신과 포스코의 혁신패턴 연구

김소형 한국유통과학회 2013 유통과학연구 Vol.11 No.6

Purpose - Studies of mechanism as a competitive strategy, a relatively new field in the study of strategic management research, has recently drawn the attention of the business management scholars. The literature has so far proposed the subjective-based view, environment-based view, and the resource-based view in its analyses of firm management. Hence, it is highly likely for the firm management to be reasonably thought of as a combination of and interaction among the three key elements of subject, environment, and resources this is the mechanism-based view (MBV). It is reasonable to consider firm management to be the combination of and interaction among the three key elements of subject, environment, and resources. The overall dynamic process that integrates these three elements and creates functional harmony is identified as the mechanism, the principle of firm management. Much of the extant literatures on MBV has mainly focused on case studies, a qualitative approach prone to subjectivity of the researcher, although the intuition from the study may lead to meaningful insights into a firm-specific mechanism. This study’s focus is also on case analysis, but it still attempts a quantitative approach in order to reach a scientific and systematic understanding of the MBV. Research design, data, and methodology - I used both a qualitative and quantitative approach to a single model, given the complexity of the innovation processes. I conducted in-depth interviews with POSCO employees—20 from general management, two from human resources, eight from information technology, five from finance and accounting, and five from production and logistics management. Once the innovative events were selected, the interview results were double-checked by the interviewees themselves to ensure the accuracy of the answers recorded. Based on the interview, I then conducted statistical validation using the survey results as well. Results - This study analyzes the building process of innovation and the effect of the mechanism pattern on innovation by examining the case of POSCO, which has survived over the past 21 years. I apply a new analytical tool to study mechanism innovation types, perform a new classification, and describe the interrelationships among the mechanism factors. This process allows me to see how the "Subject"factor interacts with the other factors. I found that, in the innovation process of the adoption stage, Subject had a mediating effect but that the mediating effect of resource and performance was smaller than the effect of Subject on performance alone. During the implementation stage, the mediating effect of Subject increased. Conclusion - Therefore, I have confirmed that the subject utilizes resources reasonably and efficiently. I have also advanced mechanism studies: whereas the field’s research methods have been largely confined to single case studies, I have used both qualitative and quantitative methods to examine the relationships among mechanisms.

삼국~통일신라시대 다각형건물의 발생 배경에 관한 연구

金素亨 중부고고학회 2006 고고학 Vol.5 No.2

본고에서는 삼국~통일신라시대의 다각형건물 발생 배경에 대해서 살펴보았다. 다각형건물의 발생 배경에 대한 기존 학설은 불교의 영향을 받아 등장하게 되었고, 방형건물에 비해 화려한 외관으로 주로 종교적인 건물로 사용되었다고 보는 견해가 대세를 이루고 있다. 그러나 고구려의 유적인 환도산성에서는 불교 공인 이전에 축조된 팔각형건물지가 확인되었고, 불경이나 각종 기록에 팔각형에 대한 유래나 의미에 대해서 언급하고 있는 것이 전혀 없어, 기존 학설로는 팔각형 평면의 사용에 대해 해석하기 어려운 몇가지 문제점이 있다. 따라서 금번 연구에서는 종교적 측면에서의 연구에서 벗어나 그 동안 비교적 소홀히 다루어져 온 구조적인 측면에 초점을 맞추어 다각형건물의 등장 배경에 대해서 확인해보았다. 구조적인 측면에서의 접근은 다각형건물이 중층구조를 이루고 있다는 공통점으로 가지고 있다는 것에서 실마리를 얻었다. 중국에 현존하고 있는 고층의 다각형전탑과 삼국~통일신라시대의 다각형건물지의 분포를 분석한 결과, 다각형 평면은 지진에 대해서 구조적인 안정화를 이루기 위해 원형에 가까운 평면을 취해야 했기 때문에 사용되었을 가능성이 있음을 확인하였다. The present study has taken a closer look at the origin the polygon shaped buildings in the Age of Three Kingdoms and The United Silla Dynasty. The incumbent theory takes a view that Buddhism was a main influential factor for the origin of polygon building. And also, it argues that the splendid appearance of polygon structure in contrast to rectangular structure had drawn much attraction, so that the polygon building had been used for the religious ceremony. However, the site of Whan-Do mountain fortress of Goguryeo has shown the existence of octagonal buildings prior to the introduction of Buddhism in Korea. Futhermore, no descriptions were found about the meaning and the origin of octagonal building in Buddhist scriptures. These problems have shown limitations on the existing theory for the origin of polygon buildings. Thus, in the present work more emphases will be placed on the structural aspect for the study on the origin of polygon building. In studying structural aspects, one should notice that there are something in common with the polygon shaped buildings: in that they are multi-roofed structure. Analyzing the distribution of the geographical locations of the present time high-storied polygonal brick pagodas in China and polygon shaped buildings in Three kingdom period and The United Silla Dynasty, we found that polygon structure close to circular shape was widely used to maintain the stability of multi-roofed structure against earthquakes.
