Study Design: This is a retrospective review Objectives: We wanted to evaluate the clinical and radiological outcomes of operative treatment for lumbar degenerative diseases in patients who are undergoing dialysis. Summary of the Literature Review: Operative treatment for patients having spinal diseases with chronic renal failure (CRF) demands special consideration because of the medical and surgical complications and the poor clinical outcome. There are only few reports on operative treatment for lumbar degenerative diseases for patients who are undergoing dialysis. Materials and Methods: Eight patients with lumbar degenerative spondylopathy and CRF and who were undergoing dialysis were operated on from August 1998 to September 2007. The clinical and radiological outcomes were evaluated using the Japanese Orthopaedic Association (JOA) scale and the plain X-rays. The serum alkaline phosphatase levels were measured to evaluate the bone metabolism along with the postoperative improvement of clinical symptom. Results: We had 1 case of postoperative mortality with peritoneal dialysis due to sepsis that was caused by panperitonitis and another complication of discitis. Only 1 of 4 cases that underwent fusion procedure had radiological bony union. The mean JOA scores were 12.0(range: 10-14) preoperatively and 17.3 (range: 5-20) and 15.6 (range: 9-19) at postoperative 6 months and the final follow-up, respectively (p<0.05). The mean serum alkaline phosphatase levels were 80.9 (range: 43-142) preoperatively, 98 (range: 68-164) at postoperative 1month, 75 (range: 50-102) at postoperative 6 months and 108 (range: 60-209) at the final follow-up (p>0.05). Conclusions: The clinical outcomes of surgical treatments were improved for the degenerative spine disease patients who are undergoing dialysis. However after the fusion procedure, the bony fusion rate was low (25%). Since a high rate of perioperative medical complications can be expected, thorough medical evaluation during preoperation and postoperation is recommended. 연구 계획: 후향적 연구연구 목적: 투석 시행 중인 만성신부전 환자 중 요추부 퇴행성 질환 환자에 대해 수술적 치료를 시행 후 임상적 및 방사선학적 결과 대해 평가한다. 선행 문헌의 요약: 만성 신부전환자의 척추 질환의 치료에 있어서 수술적 치료는 수술과 관련된 내과적 및 외과적 합병증 및 불량한 임상 경과 등으로인한 특별한 고려가 요구된다. 투석을 시행하는 요추부 퇴행성 질환 치료환자에 대한 수술적 치료의 결과에 대한 보고가 부족하다. 대상 및 방법: 1998년 8월부터 2007년 9월까지 투석 시행하던 요추부 퇴행성 환자 중 수술적 치료를 시행한 8명의 환자에 대해, 임상결과와 방사선학적 결과에 대해 각각 Japanese Orthopaedic Association (JOA) scale과, 추시시 시행한 단순 방사선검사를 이용하여 평가하였다. 혈중 알칼리성 탈인산가수분해효소(serum alkaline phosphatase)를 측정하여, 술 후 임상증상 호전에 따른 활동도 변화에 대한 골 흡수-형성 대사 변화에 대해 간접 평가하였다. 결과: 수술 치료 후 복막투석중인 환자 1예에서 술 후 범발성 복막염에 이은 패혈증으로 사망하였고, 1예의 술 후 디스크 감염이 발생하였다. 방사선학적 평가 결과, 유합술을 시행한 4예 중 1예에서 골유합을 보였다. 평균 JOA scores는 술 전 12.0(10-14)에서 술 후 6개월째 17.3(5-20)으로 호전되었고,최종추시시 15.6(9-19)으로 감소하였다(p<0.05). 혈중 알칼리성 탈인산화효소 레벨은 술 전 80.9(43-142)에서 술 후 1개월과 6개월에 각각 98(68-164),75(50-102)으로 감소하였고, 최종 추시시 108(60-209)로 다시 증가하였다(p>0.05). 결론: 투석환자에서 시행한 요추부 퇴행성 질환에 대한 수술적 치료로 환자의 임상적 증상은 호전되었으며, 골 유합술 시행시 유합률은 떨어지는 것으로 관찰되었다(25%). 수술과 연관된 합병증 발생이 높게 예상되는 만큼 술 전 및 술 후 철저한 의학적 평가가 권장된다.

공주 반죽동 출토 백제 기와의 기초적 검토 - 대통사 창건 수막새의 모색 -

이병호 공주대학교 백제문화연구소 2022 백제문화 Vol.- No.67

This study aimed to analyze the convex roof-end tiles and convex roof tiles of the Baekje Period unearthed at Banjuk-dong, Gongju, ascertain whether they were used at the time of the foundation of Daetongsa Temple(大通寺), and gain a deeper understanding of the roof tile production system and their historic significance. Chapter 2 classifies the convex roof-end tiles of Baekje found at 176, 197-1, 204-1, and 205- 1 Banjuk-dong, Gongju into thirteen types according to their decorative patterns and production techniques, and reviews their features. It also classifies convex roof tiles by type, with the focus on tiered convex roof tiles, and examines how convex roof tiles were combined with the thirteen types of convex roof-end tiles. As a result, it has been ascertained that the convex roof-end tiles (Types 1-3) with embossed lotus petal patterns are associated with the convex roof tiles (Types 6-8), which were made with the clay ring-rim/clay tablet molding/convex roof tile’s tiered end-related A1-A2 techniques. The convex roof-end tiles (Types 4-7) with raised lotus petals are highly likely to be associated with the convex roof tiles (Types 1-5) made with a clay ring-rim molding and those made with the tiered end-related A1 technique. Chapter 3 addresses the system of producing roof tiles used at the time of the foundation of Daetongsa Temple. The convex roof-end tiles used at that time correspond to the embossed petal patterns (Types 1-2) and petal patterns with the end raised sharply (Types 4-6) in light of the number of those unearthed and the relevant chronology. The tiles with embossed petal patterns appear to have been influenced by the roof tile production skills of the Southern Dynasties of China in many ways, whereas those with petal patterns and a raised end appear to be closely related with the roof tiles of the Northern Dynasties of China and Goguryeo rather than with those of the Southern Dynasties of China. Likewise, the concave roof-end tiles and concave roof tiles unearthed from Banjuk-dong do not completely match the roof tiles of Nanjing, and are rather mixed with elements associated with the Northern Dynasties of China. The fact that the influences of both the Southern and Northern Dynasties of China and Goguryeo have been identified in the roof tiles of the Ungjin-Baekje period is attributable to the earlier adoption of the roof tile production skills of these three dynasties during the Hanseong-Baekje period. It was initially assumed that a system for supplying roof tiles from multiple workshops was established by the time of the foundation of Daetongsa Temple, and this was in fact ascertained by an analysis of roof tiles inscribed with the Chinese characters “大通” (pronounced “Daetong”). It is thought that the decorative patterns, production methods, and production system related with the roof tiles used at the time of the foundation of Daetongsa Temple had a significant influence on the roof tiles of Silla and Japan as well as those of Sabi-Baekje. 이 글은 공주 반죽동 일대에서 출토된 백제 수막새와 수키와를 분석하여, 그것이 백제 大通寺 창건기에 사 용된 기와라는 것을 밝히고, 그 제작시기와 계통, 역사적 의미 등을 파악하기 위해 작성되었다. 2장에서는 공 주 반죽동 197-1번지, 204-1번지, 205-1번지, 176번지에서 발견된 백제 수막새에 대해 문양과 제작기법을 근거로 13형식으로 분류하고 특징을 검토하였다. 또 완형의 유단식수키와를 중심으로 하여 백제 수키와를 분류한 다음, 그러한 수키와들이 13형식의 수막새와 어떤 조합 관계를 보이는지를 파악하였다. 그 결과 연꽃잎 이 원형돌기형을 이루는 1~3형식 수막새는 점토띠·점토판 성형, 미구 A1·A2기법이 구사된 6~8형식의 수 키와들과 연관성을 가지며, 연판의 끝이 융기하는 4~7형식 수막새는 점토띠 성형, 미구 A1기법으로 제작된 1~5형식 수키와와 관련된다는 것을 확인하였다. 3장에서는 대통사 창건 기와를 설정하고 계통의 문제를 다루었다. 대통사 창건기의 수막새는 출토 수량이 나 편년에 근거할 때 원형돌기형(1·2형식)과 판단융기형(4~6형식)이 해당한다. 그중 원형돌기형은 남조 기 와 제작기술의 영향이 다수 확인되지만, 판단융기형은 남조보다는 오히려 북조나 고구려 기와와의 관련성이 높다고 생각된다. 반죽동 출토 암막새나 암키와 역시 南京 출토 기와들과 완전히 일치하지는 않고, 오히려 북조·고구려적 요소가 섞여 있다. 웅진기 백제 기와에 남조뿐 아니라 북조나 고구려의 영향이 확인되는 현상은 백제에서는 한성기에 이미 중국 남북조나 고구려의 기와 제작기술이 유입되어 있었기 때문으로 보인다. 대통사 창건기 기와들은 복수의 공방에서 기와를 공급받는 생산체제가 성립된 것으로 보이는데, 이는 ‘大通’명 문자기와에 관한 분석에서도 확인되었다. 대통사 창건기 기와에서 확인되는 문양과 제작기법, 계통이나 생산체제 등은 사비기 백제 기와는 물론 신라나 일본의 기와 제작기술에도 많은 영향을 준 것으로 생각된다.

에밀레종의 萬波息笛音管의 기능을 살리는 方策

이병호 한국음향학회 2000 韓國音響學會誌 Vol.19 No.6

The Bell King Songdok the Great tolls magnificient sound that would be a great vehicle which brings all beings to the Sutras. Since 693, there was a magic flute, MANPASIKJUK, which was in existence in Shilla Dynasty that could lull all the evil-wawes, such an plaques, storms, Droughts, Famines and even Enemies. Thus, a sound tube, MANPASIKJUK, was erected in the crown of the Bell Songdok the Great so as to be effective to emit the nominal frequency tone whenever the Bell tolls for the national prosperity and welfare the People. Therefore, the Bell makers tried to fine the transmissibility condition through the sound tubr, several times during 34 years, However, it seems to be unfinished. Ever since, all of the korean Brahman Bell have the sound tubes of MANPASIKJUK, but none is performed their own functions. Here, one of the way to let the function of the sound tube of MANPASIKJUK out in the Bell Songdok the Great is proposed. There are two steps: the 1st is to elongate 18cm to the present length 77cm to fulfill the transmissibility condition for the nominal frequency of sound is emitted through the corrected sound tybe. 2nd step is to rise to 95% of the emission of the tone of nominal frequency, so that an exponential hem with the flare constant 2.8m-1, length 2.259m and the radius of the mouth 1.772m is to be extended to the corrected sound tube.

皇龍寺 49萬소斤 巨鐘은 어디로

이병호,Lee, Byung-Ho 한국음향학회 1997 韓國音響學會誌 Vol.16 No.6

작금에 皇龍寺 49萬소斤 巨鐘의 행방이 문제가 되는 것은, 최근 경주시가 그 종을 찾아서, 우리 민족 문화의 국보를 되살리고, 이를 경주 황룡사 종루에 복원하면 그 종소리와 더불어 영원할 것이라는 데 있다. 그리하여 해군에서도 최신 장비를 동원하여 그 종이 빠졌다는 동해구를 뒤지고 있다. 그러나, 그 종은 고려 숙종조에 녹여 져서 신종으로 만들어 졌다는 것이 三國遺事 卷三, 皇龍寺 鐘條에 나와 있다는 것을 발견했다. 그리고, 그것을 기준으로 계산해 보니 皇龍寺 巨鐘: 무게 41.0 ton, 높이 3.14 m, 구경 2.44 m 皇龍寺 新鐘: 무게 7.4 ton, 높이 2.07 m, 구경 1.61 m임이 드러났고 종의 收率(종의 무게/입증)이 聖德大王 神鐘은 34.7 %, 皇龍寺 巨鐘은 13.6 % 임을 알았다. 그리고, 1103년에 皇龍寺 新鐘(7.4 ton)이 원 황룡사 거종이 달려있던 자리에 매달려 있다가, 1238년 11월에, 몽고 제3차 침입군에 의하여 황룡사 전체는 타 버리고, 그 新鐘은 지금의 ④번 國道의 course를 따라 토함산맥 제일 낮은 고개를 넘어, 보문양북면 大鐘川동해구로 끌려가서 동해구에서 몽고행 배에 싣다가 그 곳에 빠뜨렸다고 보여진다. 이번에 잘하면 해군이 7.4 ton의 황룡사 신종을 건질 수 있을런지 모른다. Recently, the search for the whereabout of the huge Bell Imperial-Dragon-Temple becomes a great issue. If it happens to be found out and ringing at the original location of the Bell in Kyungjoo City, the Bell might be a great national treasure and lasting to the eternity with her beautiful sound. The Bell was so huge that the total weight of the raw material put into crucibles was 497,581 Kun (289 tons), the shoulder weight 10.3 Chuk (3.14 m) and the maximum thickness 9 Chon (27.4 cm). The Bell was erected in 754 in Shilla Dynasty and was assumed to be lost during the war time by the 3rd invasion of Mongolians (1235~8). However, the author found out that the huge Bell was recast into a new small Bell (8.1 ton) in 1103 by the people of Koryu Dynasty and then the new small Bell was hung in the same position as in the original huge Bell. 135 years later, the new small Bell was carried out by Mongolian forces as a spoil of war from Kyungjoo to the Bay Tonghaegoo, through the saddle point of Mountain Toham, Yangbuk and Riber Great Bell. At the bay, Mongolian forces wished to bring back the Bell to Mongolia by a ship, but they dropped the Bell into the sea by accident. So, if this was the case, the bell at the seabed may be the new small bell (7.4 ton) but not the original huge Bell (41.0 ton) For the evaluation of missing data of the two bells, the author sets up two equations relating all the dimensions and their weights, which seems to be a useful guide to the design of bells. The results of the evaluation of the Bells are as follows. The huge Bell The new small Bell Weight 41.0 ton 7.4 ton Shoulder ht. 3.14 m 2.07 m Mouth diameter 2.468 m 1.546 m Max. thickness 27.4 cm (9 Chon) 11.9 cm (3.9 Chon)

The relationship between inbound open innovation patents and financial performance: evidence from global information technology companies

이병호,조황희,신준석 기술경영경제학회 2015 ASIAN JOURNAL OF TECHNOLOGY INNOVATION Vol.23 No.3

Most existing studies on the global information technology (IT) sector examine the causalrelationship between internally generated patents and corporate performance. However,global IT companies acquire patents not only from internal research and development(R&D), but also from inbound open innovation. Focusing on this, we examine thedifferential effects of patents from various sources, including (1) internal R&D, (2)university–industry collaboration, and (3) transaction on corporate sales, profits, and marketvalue in 28 global IT companies. We find that patents by internal R&D boost sales, profits,and corporate value. Purchased patents have small, immediate positive effects on marketvalue and profit, but do not increase sales. University –industry collaboration patents drivesales after more than two years, but negatively impact market value. Overall, internal R&Dis consistently important for sustainable corporate growth, implying that the acquisition ofideas, technologies, and human resources for internal R&D is the most effective method ofinbound open innovation. Purchased patents boost short-term growth, while university –industry collaboration is necessary for mid- and long-term growth. Our study provides thebasis for an optimal balance between internal R&D and inbound open innovation, as well asthe creation of a financial performance-oriented patent portfolio.
