네트워크상에서 바이러스 차단을 위한 방화벽 시스템의 설계 및 구현
최준호,감판규,Choe, Jun-Ho,Gam, Pan-Gyu 한국정보처리학회 2001 정보처리학회논문지 C : 정보통신,정보보안 Vol.8 No.4
컴퓨터 시스템의 데이터 파괴 및 시스템 정지 등과 같은 악의적인 일을 수행하는 컴퓨터 바이러스의 종류 및 피해가 증가되고 있으며, 이에 따른 바이러스 검사 및 치료하는 백신과 같은 프로그램을 사용하며, 또한 클라이언트용으로 Windows 시스템에서 주로 사용되어 오고 있다. 그리고 Linux와 같은 Unix계열의 시스템에서는 파일 시스템에 파일을 저장하고 난 후 백신으로 치료하는 형태를 가지고 있어 바이러스 확산에 능동적으로 대처하지 못하고 있다. 본 논문에서는 네트워크를 통해 유입되는 데이터에 대해 바이러스 감염 여부를 실시간으로 탐지하여 그 결과를 웹상에 알려주는 방화벽 시스템을 설계 및 구현하였다. 이 시스템은 기존 방화벽 보안 정책을 유지하면서 네트워크에서 유입되는 데이터에 대해 바이러스를 실시간으로 탐지해낸다. 방화벽 시스템에 대해 바이러스 탐지 모듈을 추가한 결과, 기존보다 평균 8%정도의 시간적 지연이 있음을 확인하였다.

복합 한약재 추출물 첨가가 돈육 패티의 저온저장 중 항산화 및 항균성에 미치는 영향
최준호,장애라,이봉덕,류현덕,송현파,조철훈,Choe, Jun-Ho,Jang, Ae-Ra,Lee, Bong-Deok,Liu, Xian-De,Song, Hyun-Pa,Jo, Cheor-Un 한국축산식품학회 2008 한국축산식품학회지 Vol.28 No.2
The antioxidant and antimicrobial activities of pork patties supplemented with medicinal herb extract mix were investigated. The medicinal herb extract powder was mixed at a ratio of 48.5:48.5:3.0 for Morus alba L, Lonicera flos, and Coptis chinensis, respectively. The pork was prepared and supplemented with medicinal herb extract mix (0, 0.5, 1, or 2%) and the antioxidant and antimicrobial activities were tested during storage at $4^{\circ}C$. The pH value decreased during cold storage at $4^{\circ}C$ for allsamples, however the pH of samples supplemented with herb extract mix rapidly decreased by days 5 and 10 ($p{\leq}0.05$). The total phenol content in the pork patties with herb extract mix was higher than in the control patties. The ABTS+ radical scavenging activities increased with increasing concentrations of herb extract mix from 0.5% to 2%. In addition, pork patties supplemented with herb extract mix showed an approximately 1 decimal reduction in total aerobic counts. Therefore, the addition of herb extract mix into pork patties increased the antioxidant activity and slightly improved the antimicrobial activity of pork patties during cold storage. However, the levels of added medicinal herb extract mix should be considered prior to its use in order to maintain proper sensory acceptance.

경제성 관련 계육 도체 결함과 축산물등급사에 의한 품질 A등급의 상관관계
최준호,이재청,조철훈,Choe, Jun-Ho,Lee, Jae-Cheong,Jo, Cheor-Un 한국축산식품학회 2009 한국축산식품학회지 Vol.29 No.4
To investigate the relationship between the carcass defects considered by a meat grader and quality grade A, a total of 59,700 broiler carcasses, which were reared from September 1, 2007 to August 31, 2008 and randomly selected from 597 broiler farms with 100 broilers in each farm, were graded by a meat grader using the Korean meat grading system. The average slaughter weight of the broilers increased at the 31- to 33-d age but decreased after the 37-d age. The average daily gain to grade A ratio of the broilers was highest in autumn, and the bruises, flesh blemishes, and abnormalities of the carcasses were found to have been most frequent in winter (p<0.05). The number of economical defects (EDs) increased with the increase in the slaughter age, and the correlation coefficients of the EDs and grade A were -0.88, -0.48, and -0.12 in terms of the conformation, exposed flesh/cuts/tears, and skin discolorations of the carcasses, respectively. The correlation coefficients of the non-economical defects (NEDs) and the grade A of the broiler carcasses were -0.16, -0.22, and -0.32 in terms of the feathers, alien substances, and carcass treatment, respectively. The total number of defects (EDs + NEDs) and the grade A were highly correlated (-0.93), and in particular, the correlation between the grade A and the EDs was -0.91. It can be deemed that the grade A from a meat grader is highly correlated with the EDs. Therefore, the results suggest that broiler carcass grade evaluation using a meat grading system can provide direct information on profits in the market. The resulting carcass grade of broilers can also provide the information needed to decide on a proper incentive for a farm that has attained a good quality grade.

CFD와 입자추적기법을 이용한 카펫용 Upright 청소기의 집진효율 해석
최준호(Choe Jun-Ho),리진철(Li Zhen-Zhe),허광수(Heo Kwang-Su),장인형(Jang In-Hyeong),설승윤(Seol Seung-Yun) 대한기계학회 2009 대한기계학회 춘추학술대회 Vol.2009 No.11
The drawbacks of carpet upright cleaner are low cleaning efficiency and noise. In order to estimate the cleaning efficiency of carpet upright cleaner, CFD and Particle Tracking Method are used. Using the developed method, the effect of rotational speed and wall shape was investigated. Through the case studies, it was found out that the cleaning efficiency of carpet upright cleaner can be improved by adjusting rotational speed and wall shape. The analysis method developed in this study shows the possibility to improve the cleaning efficiency of carpet upright cleaner by adjusting the interrelated design variables.

崔俊鎬(Choe Jun Ho) 일본어문학회 2017 일본어문학 Vol.76 No.-
本稿は中島敦の「北方行」に登場する主要人物と中国人登場人物に対する分析を通して、作家の持つ中国に対する認識とその特異点の一端を確認したものである。まず第一篇では黒木三造が中国へと向かう船内で瘤をもつ中国人男性と遭遇する。奇怪な雰囲気を醸し出す男性は、一気に三造の興味を惹くものの二人の間でそれ以上の交流は進まず、結局その男性は物語の展開上あくまでも三造の混沌とした精神世界の内部を際立たせるための役割に過ぎない。続く第二篇では白夫人が登場する。彼女は家中の反対を押し切って中国人男性と国際結婚を果すが、二人の一連の恋愛話からは白夫人の夫に対する宗教的な救いという使命感が読み取れる。そしてその裏側には白夫人の中国人に対する優越意識と啓蒙的な先導意識が潜んでいる。また、白夫人と中国人姑との間柄からは、お互いに対する人種的な反感と拒否の情緒が読み取れ、日本人と中国人双方に内在する差別と偏見の溝の深さが提示される。最後に折毛伝吉が登場する第三篇と第五篇では、公寓とそこの下宿人である中国人たちを分析した。そして彼らは作品の中に登場する他の日本人在留民たちとは異なり、伝吉の中国化された日常を成立させるための必要不可欠な存在であることを明らかにした。 In this article, we analyze the main characters and Chinese characters of “Hoppoukou” written by Atsushi Nakajima, and confirm the recognition of China by Nakajima and some unique aspects of it. In Chapter 1, Sanzo Kuroki (黒木三造) meets a Chinese man with a lump on the ship for China. The Chinese man has a strange atmosphere, and it attracts Sanzo’s interest. The two men, however, do not engage in any further exchange. We argue that the story introduces the Chinese man with a lump as a means of depicting Sanzo’s chaotic mental world in a vivid manner. In Chapter 2, Mrs. Shiro is introduced. She married a Chinese man despite her family’s objection to this marriage. A series of stories about this couple, we claim, reveals her religious sense of mission to salvage her husband as well as her superiority sense over Chinese people and her leading consciousness of enlightening them. Further, the relationship between Mrs. Shiro and her Chinese mother-in-law represents their racial antipathy against each other and their negative feeling towards each other, which further indicates strong discriminations and prejudices inherent to both Japanese and Chinese people. Finally, in Chapters 3 and 5, where OrigeDenkichi (折毛伝吉) is introduced, Chinese people living at an apartment in China are depicted differently from Japanese residents, and they play an essential role in describing the life style of Denkichi accustomed to the life style of Chinese people.
