인터넷 라우터에서의 패킷 분류를 위한 2차원 이진 검색 트리

이고은(Goeun Lee),임혜숙(Hyesook Lim) 대한전자공학회 2015 전자공학회논문지 Vol.52 No.6

현재의 인터넷 사용자들은 실시간으로 다양한 멀티미디어 서비스를 제공 받길 원한다. 이에 네트워크 트래픽의 속도는 매우 빨라지고 있으며, 처리하여야 하는 데이터의 양은 해마다 기하급수적으로 증가하고 있다. 데이터는 ‘패킷’이라는 단위의 데이터형식으로 전송되며, 패킷분류는 인터넷 라우터의 가장 어려운 기능 중 하나로 모든 패킷에 대하여 선속도로 처리되어야 한다. 다양한 패킷 분류 알고리즘 중, 영역분할 패킷분류 알고리즘은 5개의 패킷 헤더 필드 정보를 동시에 검색할 수 있는 효율적인 알고리즘이다. 영역 분할 사분 트라이는 가장 대표적인 영역분할 패킷분류 알고리즘으로 메모리 요구량이 적은 알고리즘이지만, 빠른 검색성능을 보장하지 못하는 단점이 있다. 본 논문에서는, 영역 분할 사분 트라이의 단점을 이진 검색 트리를 사용해 보완하는 새로운 알고리즘을 제안한다. 실험을 통하여 제안하는 알고리즘은 입력과 비교되는 룰의 수에 있어 영역 분할 사분트라이 보다 검색 성능이 향상됨을 보았다. The Internet users want to get real-time services for various multi-media applications. Network traffic rate has been rapidly increased, and data amounts that the Internet has to carry have been exponentially increased. A packet is the basic unit in transferring data at the Internet, and packet classification is one of the most challenging functionalities that routers should perform at wire-speed. Among various known packet classification algorithms, area-based quad-trie (AQT) algorithm is one of the efficient algorithms which can lookup five header fields simultaneously. As a representative space decomposition algorithm, the AQT requires a small amount of memory in storing classification rules, but it does not provide high-speed classification performance. In this paper, we propose a new packet classification algorithm by applying a binary search for the codewords of the AQT to overcome the issue of the AQT. Throughout simulation, it is shown that the proposed algorithm provides a better performance than the AQT in the number of rule comparisons with each input packet.

This case study investigates fashion brands that have entered the pet fashion market. A total of 25 cases were identified and analyzed from three perspectives: 1) product types, size systems, prices, 2) design aspects, fabrics, patterns, styles, and 3) marketing strategies. The study results are as follows. First, the product types of pet fashion are not diverse, and only the sizes of small dogs can be found. However, there is a significant price difference between brands. Second, knitted fabrics with good elasticity are mainly used for pet fashion products, and patterns incorporating their brands are extremely common. The style is casual and sporty. Third, marketing strategies should include a new line within a brand or launch a single specialized brand as a one-shot test for consumer reaction. Additionally, it has been expanded and presented as a family look to meet the needs of the petfam. Further, existing fashion brands and retail-based brands select diverse small-scale dog fashion product brands and expand their operation as a dog lifestyle total selectional shop. Therefore, brands entering the future should consider strategies such as size segmentation, product diversification, and premium price of high-quality materials that help market products such as the expansion or promotion of existing brands.

주의분산, 기다림의 이유, 시간 단서가 기다림 시간 추정에 미치는 영향

이고은(GoEun Lee),신현정(HyunJung Shin) 한국인지과학회 2012 인지과학 Vol.23 No.1

주의분산, 기다려야 하는 이유의 제공 여부, 그리고 시간 단서가 주관적 시간 판단에 미치는 영향을 검증해보기 위한 두 실험을 실시하였다. Maister(1985)[1]가 제안하는 기다림 경험의 특징에 근거하여 실험 1에서는 주의 분산과 기다리는 이유의 제공 여부의 효과를 전망적 추정법과 회고적 추정법으로 확인해 보았다. 전반적으로 객관적 시간에 비해 주관적 시간을 과대 추정하는 것으로 나타났으나, 주의분산 정도와 이유 제공 여부가 모두 유의한 차이를 초래하였다. 즉 주의분산이 적어 시간에 주의를 많이 기울일수록 그리고 이유를 제공하지 않을 때 주관적 시간을 더 길게 추정하였다. 그러나 두 변인 간의 상호작용은 없었으며, 추정법에 따른 차이도 없었다. 실험2에서는 기다리는 시간의 단서가 주어졌을 때 변인들의 효과를 검증하였다. 그 결과 실험 1과 마찬가지로 주의분산 정도와 이유 제공 여부가 유의한 차이를 보였고, 시간 추정법 간에도 유의한 차이가 나타났다. 특히 세 변인 간의 삼원 상호작용이 유의하게 나타났다. 종합적으로 두 실험의 결과는 기다려야 하는 이유가 명확할수록 비시간적인 정보에 주의를 많이 분산할수록, 추정하는 주관적 시간이 줄어드는 경향을 나타냈다. 그리고 시간흐름의 단서가 존재할 때 두 요인의 효과가 더 커지며 특히 회고적 추정에서 그러하였다. 마지막으로 기다림이라는 부정적 경험을 감소시킬 수 있는 방안과 추후 연구의 필요성을 논의하였다. Two experiments were conducted to verify how the factors of attentional dispersion, reason for waiting, and cue of time flow affect the perceived waiting time. In experiment 1, based on the characteristics of waiting experience that Maister(1985) suggested, levels of attentional dispersion and whether or not offering a reason for waiting were manipulated. Participants estimated elapsed time(the objective time was 10 minutes) using either prospective or retrospective estimation method. Overall results were that they overestimated the elapsed time regardless of the experimental conditions. However, both main effects of the attentional dispersion and the reason for waiting were statistically significant. That is, when attention was more dispersed and when the reason was given, overestimation of elapsed time was reduced. No difference was found between the two estimation methods, and none of the interaction was significant. Experiment 2 was a replication of Experiment 1 except that a cue of time flow was added by using scroll bar on a computer screen. Because it has been suggested that the cue can help us to manage the waiting time and result in differences between the two time estimation methods. The results showed that main effects of the attentional dispersion and the reason for waiting were significant as those in Experiment 1. In addition, main effect of time estimation method and the three-way interaction were also significant. None of two-way interaction was significant. That is, the perceived waiting time is much shorter in the retrospective method, and the effects of the attentional dispersion and the reason of waiting were dependent upon the estimation methods. Both experiments showed that offering a clear reason for waiting is more important than the attentional dispersion in reducing the perceived waiting time. Some implications of these results for the service industry and the future direction of research were discussed in the final section.

This study was carried out to explore the un-derstanding of evolution and genetic concepts of 596 male students attending at technical high school. These students did not take any more class about the life science concepts such as genetic and evolutionary concepts in junior high school. In order to measure the level of genetics and evolu-tion concept, we used 20 test items developed by AAAS. In order to confirm the validity and reliability of the items used, Rasch model analysis and internal consistency reliability analysis were conducted. In order to identify the change of conceptual understanding score between grades, independent test t-test, Mann-Whitney U test were used. A paired sam-ple t-test was used for comparison with previous research data for high school students. The results of this study confirm that the AAAS evolution and genetic concept assessment items are valid for measuring the conceptual understanding of technical high school students. It was confirmed that there is a degeneration of the concept understanding at a meaningful level when moving from the first grade to the second grade of technical high school. In particular, there is more con-ceptual degeneration in the genetic concept. Compared with the scores of the students in the high school, which were identified in the previous research, the concept of the first grade of the technical high school students was maintained, but it was confirmed that the conceptual degeneration pro-ceeded in the second grade. Based on the results of this study, the necessity of education on basic biology concept in tech-nical high school and concept change theory are discussed.

The term fashion sense is used in everyday conversations by consumers to refer to the ability of people who dress well in attractive ways or to refer to the competencies or expertise of fashion professionals. Despite the frequent use of the term, its concept has rarely been explored systematically. In this study, we performed in-depth interviews with 14 fashion experts to clarify the concept of fashion sense. The core elements of fashion sense were explored based on the interview results. As a result, twelve core elements were identified that included visual ability, aesthetic experience, aesthetic recognition ability, intuition, self-consciousness, self-efficacy, fashion experience, involvement in fashion, creativity, innate sense, environmental support, and development due to education. In addition to these twelve core elements, 42 supplementary elements were identified. This study is to help initiate an academic discussion of the concept of fashion sense as a competency that fashion experts should develop. The findings of this study can provide practical and educational implications for the fashion industry and academia.

번역과 선교: H.G.언더우드의 중문 기독교문헌 번역(1886-1896)

이고은 ( Lee Goeun ) 인하대학교 한국학연구소 2021 한국학연구 Vol.- No.62

본 연구는 한국 개신교 전래 초기에 내한하여 전도와 교육, 의료, 출판 등 다방면에서 중요한 행적을 남긴 미국 개신교 선교사 호러스 그랜트 언더우드(Horace G. Underwood, 1859~1916)가 중문 기독교 문헌을 한글로 번역했던 정황을 조명한다. 언더우드가 1886년 무렵부터 중문 기독교 문헌을 다수 번역하여 조선성교서회와 삼문활판소를 통해, 또는 개인적으로 발행했던 1890년대 중반까지로 연구의 범위를 설정한다. 먼저 언더우드가 번역한 것으로 알려진 중문 기독교 문헌을 소개하고, 그가 19세기 중국의 개항장 상하이를 중심으로 발행된 수많은 기독교 문헌 중 어떤 것을 가져다 번역했는지 선택상의 특징을 이야기한 뒤, 그가 번역에 힘쓴 동기와 중문 기독교 문헌을 입수하게 된 정황, 언더우드 주변의 번역자와 독자에 대해 논한다. 마지막으로 연구상의 난제로서 서적의 발행연도ㆍ발행처 표기가 불분명한 점, 영문ㆍ중문 제목의 일관성 결여, 그로 인해 같은 책이 다른 선교사에 의해 중복 번역되었을 가능성 등을 제시한다. This study shed light on the context in which Horace G. Underwood (1859-1916), an American Protestant missionary who left important achievements in evangelism, education, medical, and publishing in Korea in the early days of Korean Protestantism. The scope of this study spans from 1886 up to the mid 1890s, when he introduced a number of Chinese Christian literature to Korea and have them translated into Korean. I provide a table of Chinese Christian texts and their Korean translations known to have been translated by H.G. Underwood to discuss some features of his selection books, how he obtained those book, what motivated him to produce those translations. In addition, attention is paid to the translators around Underwood and the readers of those books. Finally, I suggest several research conundrum, such as the unclear year and place of publication of the translations, the lack of consistency in English and Chinese titles, and the possibility of duplication of translation works by other missionaries.
