초고층 건물공사에서 타워크레인의 양중계획은 전체 공사의 성패를 좌우할 수 있는 매우 중요한 요소 중 하나이다. 타워크레인의 양중계획에 있어 양중시간은 기본적인 요소 중 하나로 이를 바탕으로 양중부하 및 타워크레인을 선정하기 때문에 양중계획을 위해서는 정확한 양중시간의 예측이 필요하다고 할 수 있다. 현재 초고층 공사의 양중시간 예측은 기존의 실적자료와 시뮬레이션을 이용하여 수행하고 있지만 양중작업에 영향을 미치는 환경적인 요인에 대해서는 충분히 고려되지 못하고 있다. 따라서 본 연구에서는 양중작업에 영향을 크게 미치는 바람을 시뮬레이션에 반영하여 초고층 공사의 타워크레인 양중시간을 예측하는 시뮬레이션 모델을 개발하였다. 시뮬레이션 분석 결과 바람의 영향을 반영한 양중시간은 높이가 올라갈수록 증가하였으며, 초고층부의 경우 기계적 양중시간보다 바람의 영향에 의한 양중 지연시간이 더 크다는 것을 알 수 있었다. 또한 연구 대상지인 서울의 풍속은 4월이 강하고 10월이 약하게 나타났으며, 양중시간을 예측한 결과 둘 간의 큰 차이가 발생함을 알 수 있었다. 이 같은 결과는 향후 초고층 타워크레인 양중계획 시 바람이 양중에 미치는 영향을 예측하고 이를 고려하여 실제 상황과 동일한 양중계획을 세우는데 활용될 수 있을 것으로 기대된다. Tower crane hoisting plan is one of the key element for the success of entire High-Rise Building construction. Hoisting time is the basic factor to appropriate hoisting plan which need to the hoisting load estimate and tower crane selection. With this reason, accurate hoisting time is needed to the proper hoisting plan. The current hoisting time estimation for High-Rise Building focus on the hoisting cycle time estimation with historical data. However, this method underestimated the external influences like environmental factor. Thus, this paper aims to develop the hoisting time estimation model with discrete event simulation which include the wind influences with certain height. According to the simulation result, the hoisting time which applied wind influence is increasing with height growth. Because of the high speed wind, the upper area of building has more operation delay time than the mechanical operation time. Seoul, the research area, has the most fastest wind speed on April and the least on October. Due to these differences of wind speed, the hoisting time is estimated with significant differences between April and October. This hosting time estimation model would be used for estimating the influence of wind. Moreover, this could apply to make the realistic hoisting plan.

양종헌(Jong Heon Yang),윤성현(Sung Hyun Yoon),서재완(Jae Wan Suh),최성준(Sung Joon Choi),박현우(Hyun-Woo Park) 대한정형외과학회 2024 대한정형외과학회지 Vol.59 No.1

목적: 족관절 양과 유사 골절에서 비골 골절에 대한 정복 및 내고정술을 시행한 후 불안정성을 평가하여 경비원위결합을 고정하는것은 잘 알려진 치료법이다. 그러나 내측 삼각인대를 보강하는 술식에는 그 필요성과 효과에 대해 여전히 논란이 있다. 본 연구에서는 양과 유사 골절에서 외과 골절에 대한 고정 이후 삼각인대 보강술을 시행한 환자군과 경비인대 결합 나사 고정을 시행한 환자군 간의 치료 결과를 비교 분석하고자 한다. 대상 및 방법: 2007년부터 2022년까지 양과 유사 골절로 수술을 시행한 환자들 중 외과 골절에 대한 고정을 포함하여 삼각인대를 보강한 31명의 환자군과 경비인대 결합 고정술을 시행한 12명의 환자들을 후향적으로 비교하여 연구를 시행하였다. 술 후 12개월째 시각통증척도(visual analogue scale, VAS) score, American Orthopaedic Foot and Ankle Society (AOFAS) score, 족관절 가동 범위를 측정하여 임상적인 결과를 비교하였으며, 수술 전 후 내측간격(medial clear space), 경비겹침(tibiofibular overlap), 경비간격(tibio-fibular clear space)을 측정하여 방사선학적 결과를 비교하였다. 또한 술 후 합병증 발생 유무를 조사하여 비교하였다. 결과: 술 후 AOFAS score와 시각통증척도 score 및 술 후 가동 범위를 비교한 결과 두 군 간의 유의한 차이는 없었다. 방사선학적 결과상 수술 전 후 내측간격, 경비겹침, 경비간격은 두 군 간에 유의한 차이를 보이지 않았다. 또한 삼각인대 보강술을 시행한 군에서 술 후 합병증은 발생하지 않았으며, 경비인대 결합 나사 고정을 시행한 환자군에서는 각각 1건의 나사 파손과 천부 감염이 관찰되었다. 결론: 양과 유사 골절에서 외과 골절 고정 후 삼각인대 보강술만 단독으로 시행하더라도 임상적으로 좋은 결과를 얻을 수 있었다. 또한 경비인대 결합 고정술을 시행하는 것보다 삼각인대 보강술만 단독으로 시행하게 되면 부정 정렬의 가능성이 거의 없고, 금속나사의 파손이나 금속 나사의 제거를 위한 추가 수술이 필요하지 않은 장점이 있어, 삼각인대 보강술은 양과 유사 골절의 수술적 치료 시 좋은 치료 술식이 될 수 있을 것으로 생각된다. Purpose: The current treatment option of bimalleolar equivalent fractures is open reduction and internal fixation of lateral malleolus followed by syndesmotic screw fixation of syndesmosis or deltoid ligament augmentation. On the other hand, there is still debate using deltoid ligament augmentation technique. This study compared the clinical results of deltoid ligament augmentation and syndesmosis screw fixation in bimalleolar equivalent fractures. Materials and Methods: From 2007 to 2022, this study retrospectively compared 31 patients who underwent deltoid ligament augmentation with fibula fixation with 12 patients who underwent syndesmosis fixation for bimalleolar equivalent fractures. The clinical results were compared by measuring visual analogue scale (VAS) score, American Orthopaedic Foot and Ankle Society (AOFAS) score, and ankle range of motion 12 months after surgery. The radiological results were compared by measuring medial clear space, tibiofibular overlap, and tibiofibular clear space before and after surgery. The postoperative complications were compared. Results: The post-operative AOFAS score, the VAS score, and the ankle range of motion were similar in the two groups. The radiological results showed a similar medial clear space, tibiofibular overlap, and tibiofibular clear space in the two groups before and after surgery. In addition, there were no postoperative complications in the group that underwent deltoid ligament augmentation, and one screw break and superficial infection were observed in each of the patient groups that had undergone trans-syndesmosis screw fixation. Conclusion: Clinically good results could be obtained despite only deltoid ligament augmentation being performed alone after fibular fracture fixation in bimalleolar equivalent fractures. In addition, if only deltoid ligament augmentation is performed alone rather than transsyndesmosis screw fixation, there is little possibility of misalignment and no risk of screw breakage or the need for additional procedures to remove the screws. In conclusion, deltoid ligament repair without syndesmosis screw fixation could be viable for treating bimalleolar equivalent fractures.

A hepatoid adenocarcinoma of stomach, a subtype of gastric cancr, is characterized by a histologic resemblance to a hepatocellular carcinoma and $\alpha$-feto protein production. Another feature is early metastasis to the liver and lymph nodes, thus revealing a poor prognosis. We report a case of a hepatoid adenocarcinoma of the stomach with liver metastasis. A 52-year-old male visited our hospital with a chief complaint of indigestion. Gastroscopic examination showed a Borrmann type-II lesion on the lesser curvature of the antrum. The CT scan showed a suspected advanced gastric cancer with liver metastasis. The serum AFP level was 123 ng/ml. A radical subtotal gastrectomy and a right hemihepatectomy were performed simultaneously. Pathologic examination confirmed the lesion to be confined to the submucosa. The gastric lesion was a hepatoid adenocarcinoma, and the hepatic lesion was a metastatic adenocarcinoma from the stomach. Therefore, he was classified as having stage IV (T1N1M1) gastric cancer. In cases of a hepatoid adenocarcinoma of the stomach, even patients with early gastric cancer can be staged into the poor prognostic group. 위암의 한 아형인 간양 선암은 조직학적으로 간세포암종과 형태학적으로 유사하며 알파태아단백 생산을 특징으로 한다. 간양 선암의 또 하나의 특징은 간과 림프절로의 조기 전이를 함으로써 불량한 예후를 갖는다는 것이다. 저자들은 간전이를 동반한 위의 간양 선암 1예를 보고하고자 한다. 소화불량을 주소로 내원한 52세 남자 환자는 위내시경 검사상 Borrmann 제2형 병변이 위암이 의심되었다. 환자의 혈청 알파태아단백은 123 ng/ml로 증가되어 있었다. 근치적 위아전절제술과 간우엽절제술을 시행하였고 조직학적 소견상 위의 병변은 점막하층에 국한된 간양 선암이었으며 간의 병변은 위로부터 전이된 선암이었다. 결국 환자는 위암 4기(T1N1M1)로분류되었다. 위의 간양 선암은 조기병변에서도 불량한 예후군으로 분류될 수 있다.

This study was conducted to identify the potential of rape stalk as a raw material for biorefinery process of rape flower. At first, rape stalk (RS) was immersed in distilled water (DW), acetic acid (AA), oxalic acid (OA), sulfuric acid (SA) and sodium hydroxide (SH) solutions, and the content of reducing sugars liberated from immersed RS was analyzed. Glucose, xylose, arabinose and sucrose were detected varying with the immersion type. In particular, 1% AA-immersion of RS for 72 hr was the most effective conditions to liberate glucose from RS. Secondly, the RS residues were used for elementary analysis and fabrication of fuel pellets. In addition to the solution type, concentration of immersion solutions (0%, 1%, 2%) and immersion time (24, 72, 120 hr) were used as experimental factors. The contents of nitrogen, sulfur and chlorine reduced effectively through the immersion of RS in DW, AA and OA solutions. For properties of RS-based pellets, bulk density and higher heating value of RS-based pellets greatly increased with the immersion of RS, and the qualities were much higher than those of the A-grade pellet of the EN standards. Ash content decreased remarkably through the immersion of RS, and was satisfied with the A-grade pellet standard. Durability was negatively affected by the immersion of RS, and did not reached to B-grade of the EN standard. In conclusion, acid immersion of RS can be a pretreatment method for the production of fuel pellet and bioethanol, but use of the immersed RS for the production of high-quality pellets might be restricted due to low durability of immersed-RS pellets. Therefore, further studies, such as investigation of detailed immersion conditions, fabrication of mixed pellets with wooden materials and addition of binders, are needed to resolve the problems. 본 연구는 유채의 바이오리파이너리 원료화 가능성을 확인하기 위하여 유채대를 DW, AA, OA, SA 및 SH 용액에 침지하였다. 먼저 침지 유채대의 원소를 분석한 결과, 침지를 통하여 질소, 황, 염소의 함량이 효과적으로 감소되는 것을 확인하였다. 이 외에 침지액의 농도와 침지시간을 실험인자로 침지액 내에 존재하는 glucose, xylose, arabinose와 같은 유리당의 양을 조사하였는데, DW- 및 SH-침지액에서는 각각 xylose와 sucrose만 그리고 SA- 및 OA-침지액에서는 소량의 glucose만 검출되었다. 그러나 AA-침지액에서는 많은 양의 glucose와 소량의 arabinose까지 분석되었다. 한편, 유채대 침지에 사용된 산용액의 종류와 농도(1%, 2%)에 따른 glucose 양을 분석한 결과, AA를 침지액의 조제를 위한 산으로 사용하고 AA의 농도를 1%로 조절하는 것이 유채대로부터 효과적으로 glucose를 가수분해할 수 있는 조건인 것으로 조사되었다. 침지시간의 영향을 보면, 72 hr-침지에서 가장 많은 양의 glucose가 검출되었으며, 120 hr까지의 침지시간 연장은 유리되는 glucose 양에 부정적인 영향을 미쳤다. 다음으로, DW, AA, OA 용액에 침지시킨 유채대를 이용하여 펠릿을 제조하였는데, 이 때 산의 농도 그리고 침지시간(24, 72, 120 hr)을 실험 인자로 사용하였으며, 이렇게 제조된 펠릿의 함수율, 겉보기밀도, 회분량, 발열량, 내구성을 측정하였다. 침지 유채대 펠릿의 겉보기 밀도와 발열량은 무침지 유채대 펠릿과 비교하여 크게 높았으며, 실험 인자와 상관없이 EN 규격의 A등급 기준(≧600 ㎏/㎥, ≧14.1 MJ/㎏)을 각각 상회하였다. 유채대의 침지는 무침지 유채대의 회분량(8.9%)과 비교하여 회분량을 크게 감소시켰으며, 특히 AA-와 DW-침지가 유채대의 회분량 감소에 효과적인 것으로 나타났다. 또한 침지 유채대의 회분량은 EN 규격의 A등급 기준(≦ 5.0%)을 만족하였다. 침지 유채대로 제조한 펠릿의 내구성은 전반적으로 무침지 유채대 펠릿(97.40%)보다 낮았으며, 특히 OA-2%에 120 hr 침지시킨 유채대 펠릿을 제외하고 나머지 조건은 EN 규격의 B등급(≧96.00%) 기준에 만족하지 않는 것으로 조사되었다. 침지 유채대의 원소 및 유리당 분석 그리고 펠릿의 품질 시험 결과를 종합하면, 1% 농도의 AA 용액에 유채대를 72 hr동안 침지시키는 것이 유채대의 바이오에탄올 및 펠릿 원료화를 위한 최적 조건이라는 결론을 얻었다. 따라서 이 조건에서 1 ㎏의 유채대를 침지시켰을 경우, 산술적으로 바이오에탄올 생산용 원료인 50 g의 glucose를 얻을 수 있으며, 나머지 950 g의 잔사는 아그로펠릿의 원료로 사용이 가능할 것으로 생각한다. 그러나 AA-침지 유채대로 제조한 펠릿의 낮은 내구성 문제를 해결하기 위하여 세분화된 범위의 침지 조건 탐색, 목분과의 혼합 펠릿 제조, 바인더의 첨가 등과 같은 추가 연구가 수행되어야 할 것으로 생각한다.

「南朝鮮革命」論의 思想的 基礎와 戰略的 方針에 관한 硏究 : 특히 「3大革命力量强化」論을 中心으로

梁榮植 건국대학교 1987 論文集 Vol.25 No.1

In the course of opening new era to pursue peaceful unification, we today encounter with two th-reatening factors which by all means should be overcome. One of the factors is anti-democracy en-croaching upon our social structure, and the other is north Korea's threatening strategy designed to carry out revolution in the south. Heedless to say, we are obliged to take a proper step to overcome these threats with firm grasp of their true natures. This paper focuses on analysing north Korea's strategy of "the south Korean revolution", a th-reatening factor to the south. North Korea has net regarded the relation beween the south and the north as the one between brethren, who will be eventually reunited in conciliatory way, but the relation between "the re-volutionary forces" committed to injustice and "the counter-revolutionary forces" to justice. Strictly speaking, north Korea's call for reunifiction for Korea is nothing but lip-service and is con-sidered merely a dependent means to unify this country by instigating communist revolution in the south. In other words, north Korea's call for "reunification of fatherland" is not designed to simply unify this artificially divided country, but pursue complete communication and expedite the ultimate victory of the Korean revolution resorting to violence. North Korea's strategy of "the south Korean revolution" is bound to be systematized and developed into the framework of revolutionary line of anti-peace and nation, since the north has been recklessly stuck to violent revolution and class consciousness. Kim Il-sung advocates the consolidation of "the three kinds of revolutionary forces" as a basic st-rategy in a bid to materialize south Korean revolution. They are "the revolutionary forces of north Korea", "the revolutionary forces of south Korea" and "the international revolutionary forces". Revolutionary forces of north Korea, as a leading and a decisive forces among the three, will be-come a revolutionary base for the achievement of "south Korean revolution". The strengthening of the revolutionary forces of north Korea could be regarded as an attacking forces against the south under the pretext fo supporting the revolutionary forces of south Korea, while securing the structure of Kim Il-sung's leadership and the Workers' Party of Korea. Kim Il-sung regards the revolutionary forces of south Korea as a part of main forces and an el-ement to be consolidated with the revolutionary forces of north Korea in the course of ma-terializing Korean revolution at decisive moment. It could be taken for Kim's expression that if the nature of Marxist-Leninist revolutionary party playing a key role for the victory of the south Ko-rean revolution as an vanguard and a political counselor in revolutionary struggle can not be le-galized, he can not help but employ the tactics of underground operation. In fact, the strengthening the revolutionary forces of south Korea, an alter ego of the Workers' Party of Korea, is designed to form and command main forces of the revolution by mobilizing under-ground organization as a main element in the South, and to form a broad "Anti-U.S. United Front" to drive the U.S. forces out of south Korea by employing the tactics of United Front comprising every revolutionary element available. The Strengthening of struggle potential to carry out "People's Democratic Revolution" by instigating an anti-government massive popular uprising in the south is also taken into account. Kim Il-sung regards the international revolutionary forces as an international supporting forces for the achievement of both the south Korean revolution and the Korean revolution as a whole. With due regard to strengthening of the three kinds of revolutionary forces as a basis of north Korea's strategy of revolution in the south, entire northern half of the Korean peninsula seems to be utilized as a principal base of revolution, and it is not too much to say that the revolutionary forces of north Korea, in fact, should be regarded as an offensive weapon committed to indirect invasion of the south. The revolutionary forces of south Korea is a leading element among others and is mobilized in the invasion of south Korea as an indirect aggression forces by taking advantage of vulnerable points of our society. What is of prime importance here is to work out a countermeasures to cope with dual challenges designed in north Korea's strategy of south Korean revolution. In general, the following three countermeasures could be considered. First, we must seize exact essence and threatening factor implied in north Korea's strategy of south Korean revolution and brace up our strong will for the safeguard of freedom. Second, we must foster our military and economic powers utilized as deterent mechanism to block north Korea's direct military provocation, while solidifying our will for the safeguard of freedom through the establishment of sound national conciliation to dissipate indirect threat caused by political conflict at home. Third, we must be well prepared to cope with north Korea's plot to agitate our social order in such way as toadstool taking root in moldy by simply taking advantage of social vulnerability. Like social revolution has never set foot in any place of the world in the past contrary to Marxist idea, communist revolution would not take place in the south when individual freedom, democracy, well-being and national conciliation soundly prevail there. This is the valuable lesson we have learned from the history.

This investigation was undertaken to clarify the effects of consecutive application of insecticide (Hexachlorocyclohexane: HCH, 10 ppm each year) and fungicide (Tetrachloroisophthalonitrile: TPN, 40 ppm each year) on changes of the composition of soil bacterial flora in the experimental plots treated with each pesticide for two years. For these purposes, the isolating of bacterial cells growing on albumin agar plate was carried out with non-treated, HCH-treated and TPN-treated soil. And these isolated strains were grouping in accordance with the first diagnostic table of Cowan & Steel based on the morphological and physiological characteristics of bacterial cells. The mortality rate of bacteria was 30% in control, 44% in HCH and 51% in TPN plot respectively, in the process of obtaining pure culture. This suggests that the application of HCH or TPN enriched the fastidious bacteria in soil. The proportion of Gram-negative strains to the total isolates was 37% in control, 37% in HCH and 75% in TPN plot respectively. This means that the application of TPN enriched Gram-negative strains in soil. And the application of TPN increased the number of Gram-negative, nonspore-forming strains, and meanwhile decreased the number of spore-forming strains. In the results, the application of HCH or TPN changed considerably the composition of soil bacterial flora. And the influences of HCH and TPH on changes of the composition of soil bacterial flora were not equal each to each. 밭토양(土壤)에서 살충제(殺蟲劑) Hexachlorocyclohexane(HCH) 및 살균제(殺菌劑) Tetrachloroisophthalonitrile(TPN)의 연용(連用)이 토양세균(土壤細菌) flora의 구성(構成)을 어떻게 변화(變化)시키는가를 검토(檢討)하기 위하여 HCH 및 TPN을 년(年)1회(回) 2년간(年間) 연용(連用)한 각실험구(各實驗區) 그리고 대조구(對照區)로서 농약(農藥) 무처리구(無處理區)로부터 단리(單離)한 세균세포(細菌細胞)의 현미경적(顯微鏡的) 관찰(觀察)과 생리적(生理的) 시험(試驗)을 하였다. 그리고 이 형태적(形態的) 및 생리적(生理的) 결과(結果)에 기초(基礎)한 Cowan & Steel의 제(弟)1차(次) 감별기준(鑑別基準)에 따라 이들 단리균주(單離菌株)를 Grouping하여 다음과 같은 결과(結果)를 얻었다. 1. 희석평판법(稀釋平板法)에 의한 알부민 한천배지상(寒天培地上)에 형성(形成)된 micro-colony를 육즙한천배지(肉汁寒天培地)에 이식배양(移植培養)하여 순수분리(純粹分離)하는 과정(過程)에서 많은 세균(細菌)이 사멸(死滅)하였는데 대조구(對照區)에서 30%, HCH구(區)에서 44%, TPN구(區)에서 51%의 사멸률(死滅率)을 각각 보였다. 이는 이들 농약(農藥)의 연용(連用)에 의하여 사멸(死滅)하기 쉬운 즉(卽) 영양요구성(營養要求性)이 복잡(複雜)한 세균군(細菌群)이 토양(土壤)중에 집적(集績)되었음을 시사(示唆)한다. 2. 전단리균주(全單離菌株)에 대한 그람음성세균(陰性細菌)은 대조구(對照區)에서 37%, HCH구(區)에서 37%, TPN구(區)에서 75%를 각각 나타내어 TPN은 그람음성세균군(陰性細菌群)을 토양(土壤)중에 우점(優占)시켰다. 3. 각실험구(各實驗區)로부터 단리(單離)된 균주(菌株)에 대한 현미경적(顯微鏡的) 관찰(觀察)과 생리적(生理的) 시험결과(試驗結果)로부터 HCH와 TPN은 서로 다른 pattern으로 토양세균(土壤細菌) flora의 구성(構成)을 변화(變化)시켰다. 4. 전단리균주(全單離菌株)에 대한 포자형성세균(胞子形成細菌)은 대조구(對照區)에서 77%, HCH구(區)에서 40%, TPN구(區)에서 0%를 각각 나타내어 농약처리구(農藥處理區)에서 포여형성세균군(胞予形成細菌群)이 저하(低下)되었고, 특(特)히 TPN구(區)에서는 포자형성균(胞子形成菌)이 전(全)혀 분리(分離)되지 않았다. 5.

The Yang geum mentioned Guracheolsahyeongeum (歐邏鐵絃琴) by Yeonam Park, Ji-won in Western Yang guem. Originally,Yang geum was a sort of Dulcimer. It has been translated and spread to the world under the names such as Tympanon, Harkvert, Cembalo and Yangqin. Actually new traditional music composition skills in Korea are represented and required in several ways through the Modernized Yang Geum, but the real state of a study on sign system of the modernized Yang Geum`` new performing technique is poor. Accordingly, this study was made to develop a newly improved Yang Geum``s performing technique sign system by searching the existing Chinese Yangqin, Korean Traditional Yang Geum and Modernized Yang Geum``s performing technique sign systems. Yang Geum has been actively played, studied and improved as a folk musical instrument of the world, while the Korean Yang Geum research has continued to have little on traditional music. The Korean Traditional Yang Geum is dominated mainly by one-handed technique, whose tune is frequently changed by environment. And popular acceptance is poor due to the limit of the instrument noisy tuning. As a result, China``s Modernized Yang Geum Performing Technique Sign has been systematically studied for a long time and organized and mentioned on the first top part of any manual. This notated a special technique playing in commonly used sign when playing the Modernized Yang Geum Performing that led to the correct Modernized Yang Geum performing expression. First, the Chinese Modernized Yang Geum is composed by staff notation and number notation, and the correct technique training is good by the notation system of performing technique. Second, the Korean Traditional Yang Geum is composed by staff notation(except jungganbo), and the notation sign system ofjungganbo was used by the notation sign system of performing technique when having reverse score of staff notation. Third, Korea``s 18strings Modernized Yang Geum improved the musical instrument by magnifying the register of the Korean Traditional Yang Geum and the notation system was notated by the staff notation of the West.
