저위교합이란 능동적 맹출기 동안이나 이후 해당치아의 교합면 방향으로의 성장이 멈추어 다른 치아들보다 하방에 존재하는 것을 말한다 저위교합치의 결과로 침하치의 만기잔존, 부정교합, 증가된 치아우식 감수성과 치주질환의 가능성, 계승치의 이동 등이 나타날 수 있다. 따라서 조기진단 및 적절한 처치가 필요하다. 저위교합치의 치료는 저위교합 정도나 후속 영구치의 발육정도에 따라 보존에서 발치까지 다양하다. 영구 계승치가 없거나 부분적인 침하치가 치주적으로 건전한 경우, 공간문제를 발생하지 않는 경우 보존적인 접근이 추천되기도 한다. 그러나 계승치가 존재하고 맹출이 지연되는 경우, 국소적인 염증반응과 관련되는 경우 교정적인 치료가 필요한 경우에는 발거가 필요할 수도 있다. 특히 저위교합된 유구치의 상방으로 인접치가 경사되어 악궁장경에 문제를 초래할 위험이 있는 경우 외과적인 발치가 필요할 수도 있으며 경사가 심한 경우 발치를 위한 외과적 접근이 힘들 수 있다. 심하게 경사된 인접치로 인하여 저위교합치의 외과적 발거가 힘들 환아에서 가철성 교정장치를 이용하여 공간확보를 진행 하였으며 보다 용이하게 치아를 발거할 수 있었다. Infraclusion may be defined as teeth that stop their relative occlusal movement in the dental arches during or after the period of active eruption and then remain under the occlusal plane. Delayed exfoliation, malocclusion, increased susceptibility to dental caries and periodontal disease of both the neighboring teeth and retained molar, and dislocation of' the successor are the consequencces of infraclusion of primary molars. Therefore, early diagnosis and appropriate treatments are necessary. The therapeutic approach of' the infracluded teeth varied from preservation to extraction. The teeth with simple infraclusion without any signs of interference with occlusal and jaw development may be examined periodically with fellow-up check and radiographically. However, if the infracluded tooth interferes with normal eruption of successor or shows any sign of delayed resorption, or the tipping of adjacent teeth or supraeruption of op-posing teeth is expected, the teeth inflicted should be extracted and appropriate measures should be provided in order to maintain the normal development of occlusion and dentition. The adjacent teeth which have been collapsed over a infracluded deciduous teeth can disturb the arch length perimeter. In such cases, surgical approach might be necessary, although it would be difficult when teeth are severly leaned. However, an easier surgical access have been obtained by space regaining procedures, in young patients whose arch length has been shortened due to the infracluded teeth.

低蛋白 食餌로 成長한 흰쥐에 CCl₄投與가 肝損傷에 미치는 影響을 觀察할 目的으로 Sprague-Dowley 系 흰주 암컷을 飼料 100g 當 methionine 5㎎, L-lysine은 1㎎을 8% casein 食餌에 添加한 食餌條件을 低蛋白 食餌群으로 하고 15% casein에 低蛋白 食餌群과 同一한 量의 metheionine 및 lysine을 添加한 것을 標準蛋白 食餌群으로 하여 7週間 飼育한 후 體重 100g 當 50% CCl₄의 0.13㎖을 1日 1回씩 2일동안 皮下로 注射하였으며, 이때 對照群은 olive oil만 CCl₄投與群과 같은 요령으로 投與한 뒤 實驗動物을 屠殺한 후 實驗하여 다음과 같은 成績을 얻었다. 1) 低蛋白 및 標準蛋白 食餌로 7週동안 成長하는 동안 두 群사이의 體重 增加率은 有意한 差는 볼 수 없었으며 成長後 最終 臟器 무게도 兩群間에 有意한 差를 볼 수 없었다. 한편 CCl₄投與後 대체적으로 臟器(肝臟, 脾臟, 腎臟, 心臟)의 무게가 增加되었으며, 이 中 肝의 무게 增加率이 가장 큰 것으로 나타났다. 또한 低蛋白 및 標準蛋白 食餌群間에 CCl₄投與로 因한 臟器 무게의 變動은 대체적으로 低蛋白 食餌群이 標準蛋白 食餌群보다 적게 나타나는 樣狀을 보였으며 特히 다른 臟器에 비해 肝의 무게 增加率이 低蛋白食餌群에서 低下되었다. 2) CCl₄投與로 因한 肝細胞의 蛋白質 含量이 모두 減少되는 傾向을 보였으나 有意性은 없었으며 低蛋白 食餌群이 標準蛋白 食群보다 肝細胞質의 蛋白質 減少率이 低下되었다. 3) CCl₄投與後 標準蛋白 食餌群에서 血淸 GPT, GDA 活性은 顯著히 增加되었으며 低蛋白 食餌群의 血淸 GPT 活性은 有意한 增加를 보였으나(P<0.001) 標準食餌群보다는 增加率이 低下 되었고 血淸 GDA 活性의 變種은 低蛋白 食餌群에서는 對照群에 比해서 약간 增加되는 傾向을 보였으나 有意性은 없었으며 標準食餌群보다는 그 增加率이 低下됨을 알 수 있었다. 한편 CCl₄投與후 肝組織의 GPT活性値가 低蛋白 및 標準蛋白食餌群의 兩群 모두 減少되는 傾向을 보였으나 意義있는 變種은 아니었으며 兩群사이의 減少率은 有意한 差를 볼 수 없었다. 또한 CCl₄投與로 因한 肝 GDA活性의 變動은 標準蛋白 食餌群에서는 약간 增加되는 傾向을 보였으나 意義있는 變動은 볼 수 없었으며 低蛋白 食餌群에서는 有意한 增加를 보였다. (P<0.001) 以上 實驗成績을 綜合하여 볼 때 低蛋白食餌 條件으로 成長한 흰쥐가 標準蛋白 食餌群으로 成長한 흰쥐에 비하여 CCl₄로 因한 肝損傷이 적게 나타나는 것으로 생각된다. The effect of hepatic injury produced by carbon tetrachloride (CCl₄: 0.65㎖/㎏; S.C.) was studied on female rats receiving a low protein-high carbohydrate (8% casein) and a standard protein-low carbohydrate (15% casein) diet, supplemented with 5㎎ of methionine and 1㎎ of lysine in both diets. The weights of internal organs, i. e., heart liver, kidney and spleen, were generally elevated by the injection of CCl₄ to female rate fed low or standard protein diet. Especially the increase of liver weight was the highest whereas the liver weight increment of rats fed standard protein diet was greater than those fed low protein diet by the injection of CCl₄. In general, the other orgains weights of rats fed low protein diet were a tendency to remain stable as compared with those of rats fed standard protein diet during the acute intoxication of CCl₄. The injection of CCl₄ showed a greater degree of serum GPT, GDA activities in animals fed the standard protein diet as against those fed a low protein diet. On the other hand, the low degree of hepatic protein content was a tendency to reduce in rats fed low protein diet as against those fed a standard protein diet. In conclusion, the effect of low protein intake in increasing the degree of hepatic damage does not seem to be present when CCl₄ is the injuring agent.

임진왜란 극복과 온양방씨의 역할에 관한 고찰

방성석(Bang Seong Seok) 순천향대학교 이순신연구소 2016 이순신연구논총 Vol.- No.25

This writing is a paper which considered the role and contribution of the figures from the Bangs of Onyang who took the lead in national salvation with their patriotism when the Joseon Dynasty was faced with the crisis of a fall due to Japanese invasion of Korea in 1592, Nagan governor Bang, Deok-ryong, and Gungwanbujang Bang, Eung-won were the heroes of the naval forces of the Joseon Dynasty who were killed in action at the naval battle at Noryang, together with the commander of Navy Headquarters of Three Provinces, Yi, Sun-sin. Bang, jin(Yi,Sun-shin’s father-in-law)worked as Boseong governor became a hero of national salvation by leading a young man named Yi, Sun-sin to the career of a military officer and directing Yi, Sun-sin’s martial arts, so Bang, Jin was the very man of highest merit in saving the country. The intelligent wife of Yi, Sun-sin, Ma’am Bang was Jeonggyeongbuin(a title of nobility) who assisted Yi, Sun-sin with her bright wisdom and honest womanly virtues. Like this, there existed the role of many Bangs of Onyang who contributed to the defeat of Japanese invaders, and conquest of Japanese invasion of Korea in 1592 directly and indirectly. On April 13, 1592, the Japanese troops attacked the coastal water of Jeolyeong-do Island. In the year of Imjin(Dragon), the Japanese invaders started war, so it is called Japanese Invasion of Korea in 1592. Japan’s invasion of the Joseon Dynasty was derived from Toyotomi Hideyosi’s absurd ambition of using Joseon as a bridgehead in a bid to conquer the Ming Dynasty. Accordingly, the Japanese Invasion of Korea in 1592 is an international war in Northeast Asia, in which Joseon, Japan and Ming engaged in warfare. However, there were only the losers with no winner in this war. If so, isn’t there truly a winner in Japanese Invasion of Korea in 1592? No! There was only one person-Chungmugong Yi, Sun-sin. There existed the command ability of the controlling commander, Yi, Sun-sin of the naval forces of Joseon, who controlled the up-and-down organization of the naval forces of Joseon consistently, and the tactical ability of the controlling commander Yi, Sun-sin, which was shown to the commanders of Japan and Ming state in every naval battle. The volition for complete victory of the Japanese troops, which got successive defeats by Josen naval forces, was thoroughly collapsed; consequently, Joseon’s fate, which was hanging by a thread, was able to restore from death. No matter who may say, the only winner of Japanese Invasion of Korea in 1592 is the hero of national salvation, Chungmugong Yi, Sun-sin. The fact that the history of the parties involved in the international war between Joseon, Japan and Ming state commonly records Chungmugong Yi,Sun-shin as a hero of victory is the very evidence. If so, is a hero truly self-achieved? There were the well-known assistants, and also cooperators who didn’t get the limelight. For example, there were high-ranking officials who helped and trusted Yi, Sun-sin, and subordinates who trusted and followed Yi, Sun-sin as well as the people who relied on Yi, Sun-sin. Among others, there were the relatives of Yis of Deoksu who shared blood with Yi, Sun-sin, and wife’s relatives of the Bangs of Onyang who tied blood with Yi, Sun-sin. The reason for not overlooking their sacrifices and sincere loyalty is that the sacrifice given unconditionally, and love given unsparingly can be displayed more powerfully when the givers are only the family members. That’s why the very patriotism displayed by the meritorious retainers of Yi, Sun-sin’s wife’s relatives from the Bangs of Onyong for saving the country can be said to be a vital role in, and contribution to the conquest of Japanese Invasion of Korea in 1592. Also, that’s why this paper consider Nagan governor Bang, Deok-ryong, his great-grandfather Bang, Ryun, his grandfather Bang, Ho-ui, Boseong governor Bang, Jin who was Yi, Sun-sin’s father-in-law, and his only daughter and 이 글은 1592년 임진왜란으로 조선이 패망의 위기를 당했을 때 우국충정으로 구국에 앞장섰던 온양방씨 인물들의 역할과 기여를 고찰한 논문이다. 낙안군수 방덕룡과 군관부장 방응원은 삼도수군통제사 이순신과 함께 노량해전에서 전사했던 조선수군의 영웅이다. 보성군수를 지낸 장인 방진은 청년 이순신을 무인의 길로 인도하고 무예를 지도함으로써 구국의 영웅이 되었으니 곧 구국의 원훈이었다. 총명했던 아내 방씨부인은 영민한 지혜와 올곧은 부덕으로 충무공 이순신을 내조했던 정경부인이었다. 이와 같이 왜적을 물리치고 임진왜란을 극복하는데 직간접적으로 기여한 많은 온양방씨들의 역할이 있었다. 1592년 4월 13일 일본군이 부산 절영도 앞바다에 쳐들어왔다. 임진년에 왜적들이 전란을 일으켰으니 임진왜란이다. 일본의 조선 침략은 명나라를 정복하기 위해 조선을 교두보로 삼겠다는 도요토미 히데요시의 허황된 야욕에서 비롯됐다. 따라서 임진왜란은 조ㆍ일ㆍ명 3국이 함께 싸웠던 동북아시아 국제전쟁이었다. 하지만 이 전쟁은 모두가 패자일 뿐 승자는 없었다. 그렇다면 과연 임진왜란에서 승자는 없었는가, 오직 한 사람 충무공 이순신이 있었다. 조선수군의 상하조직을 일사불란하게 통솔했던 통제사 이순신의 지휘능력이 있었고, 일본과 명나라 장수들에게 해전마다 보여줬던 통제사 이순신의 전술능력이 있었다. 조선수군에게 연전연패 당했던 일본군의 전승의지는 철저히 붕괴되고 말았으니 풍전등화 같았던 조선의 운명은 기사회생할 수 있었다. 누가 뭐라 해도 임진왜란의 유일한 승자는 구국의 영웅 충무공 이순신이다. 조ㆍ일ㆍ명 국제전쟁 당사자였던 한국, 일본, 중국, 3국의 역사가 공히 충무공 이순신을 승리의 영웅으로 기록하고 있는 사실이 곧 그 증명이다. 그렇다면 과연 영웅은 혼자 이루어지는 것인가, 거기엔 잘 알려진 조력자들도 있었고 조명 받지 못한 협력자들도 있었다. 예컨대 도와주고 믿었던 대신들이 있었고 신뢰하고 따랐던 부하들이 있었고 의지하고 기댔던 백성들이 있었다. 무엇보다 피를 나눈 덕수이씨 친족들과 피를 합친 온양방씨 처족들이 있었다. 이들의 희생과 충정을 간과할 수 없는 이유는 조건 없이 주는 희생과 아낌없이 주는 사랑은 오직 가족일 때 더욱 강력하게 발휘되기 때문이다. 이순신의 처가 온양방씨 구국공신들의 우국충정이야말로 임진왜란 극복에 중요한 역할과 기여라고 할 수 있는 이유이다. 그동안 상대적으로 부각되지 않은 온양방씨 인물 중 낙안군수 방덕룡과 그의 증조부 방륜 조부 방호의, 이순신의 장인이었던 보성군수 방진과 그의 외동딸로 충무공의 아내였던 정경부인 온양방씨, 이순신의 군관부장이었던 방응원과 휘하부장이었던 목포만호 방수경, 옥포만호 방승경 등을 고찰하게 되는 이유이다.

A Numerical Analysis on the Curved Bileaflet Mechanical Heart Valve (MHV): Leaflet Motion and Blood Flow in an Elastic Blood Vessel

Bang, Jin-Seok,Choi, Choeng-Ryul,Kim, Chang-Nyung The Korean Society of Mechanical Engineers 2005 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.19 No.9

In blood flow passing through the mechanical heart valve (MHV) and elastic blood vessel, hemolysis and platelet activation causing thrombus formation can be seen owing to the shear stress in the blood. Also, fracture and deformation of leaflets can be observed depending on the shape and material properties of the leaflets which is opened and closed in a cycle. Hence, comprehensive study is needed on the hemodynamics which is associated with the motion of leaflet and elastic blood vessel in terms of fluid-structure interaction. In this paper, a numerical analysis has been performed for a three-dimensional pulsatile blood flow associated with the elastic blood vessel and curved bileaflet for multiple cycles in light of fluid-structure interaction. From this analysis fluttering phenomenon and rebound of the leaflet have been observed and recirculation and regurgitation have been found in the flow fields of the blood. Also, the pressure distribution and the radial displacement of the elastic blood vessel have been obtained. The motion of the leaflet and flow fields of the blood have shown similar tendency compared with the previous experiments carried out in other studies. The present study can contribute to the design methodology for the curved bileaflet mechanical heart valve. Furthermore, the proposed fluid-structure interaction method will be effectively used in various fields where the interaction between fluid flow and structure are involved.

Transcriptome analysis of non-small cell lung cancer and genetically matched adjacent normal tissues identifies novel prognostic marker genes

Bang, Man Seok,Kang, Keunsoo,Lee, Jung-ju,Lee, Yea-Jin,Choi, Jin Eun,Ban, Ju Yeon,Oh, Chung-Hun 한국유전학회 2017 Genes & Genomics Vol.39 No.3

<P>Lung cancer can be classified into two different types, non-small cell lung cancer (NSCLC) and small cell lung cancer. Up to 85% of lung cancer cases are NSCLC. To identify prognostic marker genes for NSCLC, we conducted 10 pairs of genetically matched transcriptome (NSCLC and adjacent normal tissues obtained from 10 patients) analysis using next-generation sequencing. Pathway analysis revealed that the genes associated with the cell cycle are highly upregulated in NSCLC. Integrative analysis of two independent NSCLC studies, 71 pairs (GSE40419) and 58 pairs (TCGA-LUAD), also confirmed that cell cycle-related genes are mostly upregulated in NSCLC. All three independent NSCLC transcriptomes concordantly identified 10 potential tumor-marker genes that are highly expressed as well as significantly altered in NSCLC. A quantitative real-time polymerase chain reaction experiment validated the altered expressions of the genes. Among them, downregulation of MFAP4 and AGER and upregulation of SPP1 genes in NSCLC compared to normal tissues were significantly associated with poor prognosis as evaluated by Kaplan-Meier survival and receiver operating characteristic analyses. A further analysis indicated that the expression ratio of MFAP4 and SPP1 or AGER and SPP1 can be used as potential prognostic marker genes for NSCLC.</P>
