오준호,장문택,Oh, Jun-Ho,Chang, Moon-Taek 대한치주과학회 2008 Journal of Periodontal & Implant Science Vol.38 No.3

Purpose: The objective of this study was to compare initial implant stability measured by RFA between different implant systems during the initial healing period. Material and Methods: Fifty-four patients (36 males/18 females) who had been treated at the Department of Periodontology, Chonbuk National University Dental Hospital during the period between January and November in 2007 were included in the study. The mean age of the subjects was 49 years old (18 to 77). A total of 104 implants (Type A: 3i $Osseotite^{(R)}$, Type B: $Replace^{(R)}$ select, Type C: ITI implant) were placed following the manufacturer's standard surgical protocols. Implant stability quotient (ISQ) readings were obtained for each implant at the time of surgery, 2-, and 4-month postoperatively. Result: No implant was failed during the observation period. At the baseline, the difference between mean ISQ values of 3 implant systems was statistically significant (p<0.05). However, at 2-, and 4-month following implant surgery, no significant difference was observed between ISQ values of the implant systems. In the same implant, the ISQ values of Type B and C implants increased (p<0.05), but those of Type A implants decreased during the 2-month healing period. The mean ISQ values of Type B and C implants showed a increasing tendency, while those of Type A implants were stable for the 4-month follow-up period. Conclusion: Within limits of this study, it can be concluded that implant design and surface topography of implant might influence the ISQ value and changing pattern during the initial healing period.

Objectives: The subject of this research is the catechism on medicine between the doctors of Joseon and Japan in the 18th century through Choson Delegation(朝鮮通信使 ). Methods: The author intended to review and analyze the contents of catechism related to Acupuncture and Moxibustion and determined the characteristics of Joseon and Japan ?s Acupuncture and Moxibustion. Results: At the time, Japanese doctors had a grasp on most theories of Acupuncture and Moxibustion and were very specialized clinically. They usually used filiform needles with various techniques, and already they had many different schools in practice. However, they wanted to know if their Acupuncture and Moxibustion skills were up to the international standard, especially to Joseon, whom they regarded as a country advanced in Acupuncture and Moxibustion. They wanted to com- pare and contrast their Acupuncture and Moxibustion with Joseon's. 18th century Joseon was high time for Acupuncture and Moxibustion. Various tools were used in surgery, and varieties of needles were used to stimulate acupuncture points. The development of tools evinces the precision of Joseon's Acupuncture and Moxibustion at the time. Also, comprehensive works such as DongUiBoGam(東醫寶鑑) and UiHaklpMun( 醫學入門) greatly influenced Acupuncture and Moxibustion. Because of this impact, it can be deduced that Acupuncture and Moxibustion emphasizing Jang(臟) and Bu(腑) organs and Internal Injury developed greatly. In addition, acupuncturist Holm(許任)'s fame continued from the 17th century into the 18th century, and his medical practice left a huge mark on not only Joseon but other eastern Asian countries as well. Conclusions: We found out the evidences that there were a lot of exchanges of acupuncture and moxibustion between Korea and Japan based of the Joseon TongShinSa (Emissary)'s record of catechism on medicine in the 18th century.

하상 인공구조물에 의해 유도되는 지하수-하천수 시스템의 상호작용

오준호,김태희,성현정,김용제,송무영,Oh, Jun-Ho,Kim, Tae-Hee,Sung, Hyun-Cheong,Kim, Yong-Je,Song, Moo-Young 한국지하수토양환경학회 2007 지하수토양환경 Vol.12 No.2

본 연구는 하상인공구조물에 의해 유도되는 지하수-하천수 시스템의 상호작용을 지하수 순환을 중심으로 연구하였다. 연구지역은 충청남도 금산군 남이면 건천리의 남이휴양림으로 연구의 목적을 달성하기 위해 수리물리적 방법(수위관측)과 수리화학적 특성(pH, EC, 주 이온분석)을 분석하였으며, 이들 자료간의 연관성을 파악하기 위해서 상호상관분석을 실시하였다. 수리물리적 방법에 의한 연구결과 하상 보 수평부의 BH-14의 수위변동은 다른 지하수관정과 비교 할 때 이중퇴행양상이 빈번하게 나타났으며, 그 폭도 크게 나타났다. 또한, 수리화학적 방법에 의해 얻은 결과를 자연추적자의 개념으로 사용해 보면 지하수인 BH-14가 하천에 유사한 성향을 나타내었다. 상관성분석결과에서 수리물리적 측면인 수위에 대한 상관성분석에서 BH-14와 하상 보에서 가장 높게 나타났으며, 반면 수리화학적 측면에 대한 상관성분석에서는 하상 보와 다리의 상관성이 가장 높게 나타났다. 이는 수위와 같은 물리적 상호작용은 용질거동 없이 압력의 전파에 의해 일어나는데 반하여 수리화학적 상호작용은 용질의 거동에 의해 반응이 일어나기 때문에 더 많은 시간이 걸리기 때문인 것으로 판단된다. 결과적으로 하상의 불투수성의 보에 의해 하천과 주변대수층의 경계조건이 바뀌고, 이때 지하수 시스템으로 유입되는 하천수에 의해 BH-14의 수위가 즉각적으로 상승하며, 수질에서 하천수적 성향을 나타내는 것으로 판단된다. 이러한 현상은 보의 수위가 높아질수록 더욱 증가하는 경향을 나타낸다. This study investigated the interaction between groundwater and stream water systems, which is caused by the artificial weir on streambed, enforcing external stresses on the groundwater system. The study area is in Nami Natural Recreation Woods located in Chungcheongnam-do Geumsan-gun Nami-myeon Geoncheon-ri. In this study both of hydrophysical methods (hydraulic head) and hyrdochemical investigations (pH, EC, major ion analysis) were applied. In order to identify the relationship between each of study results, cross-correlation analysis is performed. From results of hydrophysical methods, water level fluctuation at BH-14, installed by the weir, shows the double-recession pattern much more frequently and much higher amplitudes than the fluctuation at each of other monitoring wells. Using the results by hydrochemical investigations, hydrochemical properties at BH-14 is similar to the hydrochemical characteristics in stream water. To analyze the interrelationships between the results from each of applied methods, cross-correlation analysis was applied. Results from the correlation analyses, water levels at BH-14 and stream weir showed the highest cross-correlation in hydrophysical aspects. On the other hand, the correlation between stream weir and bridge was the highest in hydrochemical aspects. The difference between the results from each of methods is due that the hydrophysical response at BH-14, such as water level, is induced by the pressure propagation-not with mass transfer, but the hydrochemical interaction, caused by mass transport, takes much more times. In conclusion impermeable artificial weir on streambed changes the interfacial condition between the stream and surrounding aquifers. The induced water flux into the groundwater system during flood period make water level at BH-14 increase instantly and groundwater quality higly similar to the quality of stream water. Referred similarities in both of water level and water quality at BH-14 become much higher when water level at weir grow higher.

The purpose of this study is to investigate the organization and contents of "CheongKangEuiGam" and raise interests in study on Oriental Medicine in the 20th century. Songjae, LeeJongHyeong was a disciple of Cheongkang and published this book in 1984 by organizing the medical theory of Cheongkang, KimYoungHoon who lived in the turbulent period from the late period of Joseon to a chaotic state of Korea after the independence of Korea. Even though it is relatively recently published, it is a very important clinical book as well as historical material to look at the aspects of Oriental Medicine in the 20th century. The book contains several notable medical thoughts. First, you can look at one perspective of the 20th century Oriental Western medical study which is initiated by the introduction of Western Medicine in classification schemes and description of disease symptoms. In addition, he uses medicinal herbs such as Cyperus rotundus L., Pinellia ternate(Thunb.) Breit., Poria cocos Wolf, Angelica gigas Nakai, Cnidium officinale, and Paeonia lactiflora Pall as important items, it is found that qi and blood depressed gallbladder is considered as the main pathology of the disease. In terms of names and meaning of prescriptions, he prefers to use mild medicinal herbs rather than intense medicinal herbs. It seems that he tries to help people's lives with cheap and effective medicinal herbs.

열화상 스테레오 카메라를 이용한 고속 표적 거리 측정

오준호(Jun Ho Oh),이상화(Sang Hwa Lee),이부환(Boo Hwan Lee),박종일(Jong-Il Park) 제어로봇시스템학회 2011 제어로봇시스템학회 합동학술대회 논문집 Vol.1 No.2

본 논문에서는 스테레오 열상카메라를 이용하여 고온 및 고속으로 날아가는 이동체(표적)의 거리를 실시간으로 측정하는 시스템을 제안한다. 표적과 주변 환경의 온도 차이를 측정하고 고속으로 이동하는 표적의 거리를 자동으로 측정하기 위하여 열화상 스테레오 카메라 시스템을 구축하였다. 우선 열상카메라를 이용하여 취득한 고온의 표적영상으로부터 주변의 온도분포와 표적간의 온도차를 이용하여 표적영역을 검출하고, 표적의 움직임 정보와 열상 카메라 영상의 밝기정보를 결합하여 표적을 추적한다. 좌우 열상 카메라 영상에 대하여 각각 추출된 표적 영역을 중심으로 스테레오 정합을 수행하여 시차정보를 주정하고, 카메라 파라미터와 시차정보를 이용하여 실시간으로 이동하는 표적의 거리를 추정한다. 본 논문에서 제안하는 열상 스테레오 카메라 시스템을 검증하기 위하여 고온의 이동체를 촬영할 때, 3차원 궤적(x,y,z) 측정기를 함께 가동하여 표적이 이동하는 거리를 측정하여 이를 기준 거리로 설정하였다. 3차례의 비디오 데이터로부터 실험한 결과, 열화상 스테레오 카메라를 이용한 고온/고속의 이동체의 거리오차 측정 결과는 평균적으로 9.68%로 추정되었다. 스테레오 열상카메라의 타이밍 문제(jitter)를 고려하면, 실제로 추정 오차는 줄어들 것으로 판단되기 때문에, 향후 열화상카메라를 이용하는 다양한 표적의 거리 및 위치를 측정하는데 응용할 수 있을 것으로 기대된다.

Objectives : There are plenty of medical record of acupuncture & moxibustion in Traditional East Asian medicine(TEAM). We performed this study to find out the hidden criteria lies on this record to choose proper acupoints. Methods : 『Zhenjiuzishengjing』, ancient TEAM book was analysed using document clustering techniques. Corpus was made from this book. It contained 196 texts driven from each symptoms. Each texts converted to vector representing frequency of 349 acupoints. Distance of vectors calculated by weighted Euclidean distance method. According to this distances, hierarchical clustering of symptoms was builded. Results : The cluster consisted of five large groups. they had high corelation with body part; head and face, chest, abdomen, upper extremity, lower extremity, back. Conclusions : It assumes that body part of symptom is the most importance criteria of acupoints selecting. some high similar symptom vectors consolidated this result. the other criteria is cause and pathway of illness. some symptoms bound together which had common cause and pathway.
