류연석,양동식 한국고시가문학회 2005 한국시가문화연구 Vol.0 No.15

Kim Rip Shi Jib is the original text of Kim, Byeong-Yeon's(1807∼1863) collected poetry. The research about the original text of Kim Rip Sin Jib is based on Lee, Eungsoo's first, second, and final editions of which the title was changed into Satirist Kim, Satkat. The secondary texts that are used for the comparison with the main text are Kim Rip Sin Jib by Baek, Gilsoon, Park, Oyang and Chinese poetry written by Kim, Byeong-yeon and translated by Heo, Munsub, Keon, Yonghan, Kim, Yonghan, Lee, Myoungwoo which has the same contents as 『Kim Rip Shi Jib』 but only changed its title. Leaving the wrong words as unsolved led to serious mistranslation. Therefore, the wrong words handed down since Lee, Eungsoo should be thoroughly corrected. Questions can be raised about the authenticity of the poems in the collection given the problems mentioned above. Appropriate measures should be taken to solve the problem.

Usefulness of recent versions of PSPICE, personal computer implementation of the SPICE, circuit simulation computer software rogram is demonsterated in simulation of the hysteresis loops magnetic materials. In order to model the hysteresis loop of a particular magnetic core's B-H characteristics, the values of five parameters, which affect the shape of the hysteresis loops, must be established. There is no efficient procedure for selecting the values of five parameters. Neither the PSPICE instruction munual nor any current books or papers address this problem. This paper presents a method for illustrating the effect that each parameter has on the shape of the hysteresis loop.

LT, Others : PE-133 ; A case of hepatic hemangioma appearing atypical finding confirmed by dynamic MRI in patients with high risk of hepatocellular carcinoma

Background: Hemangioma is the most common benign hepatic tumor. Many hepatic hemangiomas tend to be found incidentally, but should be differentiated from malignant tumors. We report an interesting case of hepatic hemangioma in patient who has high risks of hepatocellular carcinoma. Case: A 52-year-old woman, who was a chronic alcoholic abuser and hepatitis C virus carrier with no treatment experience, was admitted due to diarrhea. The patient had suffered from intermittent abdominal pain in the right subcostal area for recent 3 months. Also the patient had easy bruising and frequent epistaxis. She had used oral contraceptives for almost 20 years. Systolic blood pressure was 160 mmHg and diastolic blood pressure was 80 mmHg. Body temperature was normal. Physical examination revealed icteric sclerae and tenderness in right upper quadrant of the abdomen. Laboratory study showed platelet count of 31,000/ul, AST/ALT of 302/127 IU/L, and total bilirubin of 2.7 mg/dl. 3-phased contrast-enhanced abdominal computed tomography (CT) revealed a 4 cm × 4 cm sized hepatic mass involving both segment 5 and 6. Abdominal CT finding suggested hepatic hemangioma, however, typical finding of hemagioma was unclear, therefore, could not rule out the malignancy. Since she had risk factors for hepatocellular carcinoma, abdominal ultrasonography was performed for further evaluation. But abdominal ultrasonography also showed atypical finding. The confirmative diagnosis could be done by dynamic magnetic resonance imaging (MRI) using primovist®, which is an innovative liver cell-specific contrast medium. Dynamic MRI presented peripheral globular enhancement and a centripetal fill-in pattern, confirmatory findings of hepatic hemangioma, on the delayed image. The patient got relief from abdominal pain and diarrhea during admission, now is being followed-up at a general out-patient clinics. Conclusions: Hemangiomas with atypical abdominal CT and ultrasonographic findings in patients with high risks of hepatocellular carcinoma can be easily characterized with primovist-enhanced dynamic MRI.

Cystic Medullary Thyroid Carcinoma: A Case of Undergoing Endoscopic Thyroid Lobectomy

Dong Hae Chung,Jae Yeon Seok,Yoo Seung Chung1,Eun Mee Oh1,Jung Won Ryu1,Young Don Lee1 대한갑상선-내분비외과학회 2015 The Koreran journal of Endocrine Surgery Vol.15 No.1

On ultrasonography, medullary thyroid carcinoma (MTC) shows hypoechogenicity, an irregular margin, a predominantly solid composition, and microcalcifications, similar to those observed in papillary thyroid carcinoma (PTC). MTC presenting as a cystic lesion is rare, and endoscopic thyroidectomy can be performed for benign thyroid masses and early stage PTC, however it is inappropriate for MTC regardless of cystic change. The authors report a case of cystic MTC found after endoscopic thyroid lobectomy and provide a review of the literature on this topic.

본 연구는 하수 종말 처리에 의해 발생되는 하수 슬러지를 잔 골재(경량골재)로 사용하여, 폴리머 콘크리트를 제조하여 그 때의 역학적 성질에 대하여 검토하였다. 하수 슬러지는 5일간 110±5℃에서 수분함량 0.1%미만으로 건조한 후 파쇄하여 No.4∼No. 200 번체의 잔골재 표준 시방서 기준에 부합되도록 사용하였다. Pellet는 보통 회전pan에서 만드나, 본 실험에서는 수동으로 제조하였다. 제조한 하수 슬러지 경량 골재는 평균 겉보기 비중은 1.58(g/㎤), 단위용적중량은 1.98(t/㎥)으로 KS F 2534의 경량골재의 절건비중과 단위용적에 따른 분류에 의하면 중위급(medium weight) 경량골재에 속하는 것으로 측정되었다. 또한 잔 골재 중 하수 슬러지 경량 골재를 0%, 5%, 10%, 15%, 20%, 25%, 30%로 치환하여 그때의 압축, 휨, 인장강도를 측정하였다. 그 결과 하수 슬러지의 증가에 따라 강도 감소를 보였으나, 일반 경량콘크리트 제조 또는 단열용 콘크리트 블록 제조에 사용이 가능하다고 사료된다. 그러므로 앞으로 건조수축, 크리이프 특성 및 내구성에 관한 연구가 더욱 심도 있게 이루어져야 폐자원인 하수 슬러지를 이용한 건자재의 개발이 가능하리라 판단된다. In this study, the polymer concrete was produced by using the lightweight aggregate that had been manufactured using the sewage sludge and its physical properties were experimentally examined. Experimental results show that when the portion of sewage sludge lightweight aggregate in the fine aggregate increases, slump values decreases. Also, the compressive, the flexural and the tensile strengths decrease when the portion of sewage sludge lightweight aggregate increases. Although its strengths decreases, the sewage sludge lightweight fine aggregates is thought to be used for construction materials.

SPICE을 利用한 硅素鐵心의 渦流에 대한 MODELING에 關한 硏究

韓運東,柳然國,梁桂儁 충주대 산업과학기술연구소 1998 産業科學論文集 Vol.6 No.-

The relation between the equivalent eddy current field He and the instantaneous flux density rate dB/dt is experimentally obtained for current transformer made of silicon steel. The results show that He is proportional to(dB/dt)-0.5~0.7 in the operating frequency range(~100Hz) of the current transformer. The AC B-H loop calcurated by combining the Jiles-Atherton model agrees well with the measured data. In addtion, this combined model allows magnetic component characteristics using SPICE to be simulated. The simulated secondary voltage waveforms of current transformers are in satisfactory agreement with the measured values.

A Peripherally Inserted Central Catheter is a Safe and Reliable Alternative to Short-Term Central Venous Catheter for the Treatment of Trauma Patients

( Dong Yeon Ryu ),( Sang Bong Lee ),( Gil Whan Kim ),( Jae Hun Kim ) 대한외상학회 2019 大韓外傷學會誌 Vol.32 No.3

Purpose: To determine whether a peripherally inserted central catheter (PICC) meets the goals of a low infection rate and long-term use in trauma patients. Methods: From January 2016 to June 2018, the medical records of patients who underwent central venous catheterization at a level I trauma center were retrospectively reviewed. Data collected included age, sex, injury severity score, site of catheterization, place of catheterization (intensive care unit [ICU], emergency department, or general ward), type of catheter, length of hospital stay during catheterization, types of cultured bacteria, time to development of central line-associated bloodstream infection (CLABSI), and complications. Results: During the study period, 333 central vein catheters (CVC) were inserted with a total of 2,626 catheter-days and 97 PICCs were placed with a total of 2,227 catheter- days. The CLABSI rate was significantly lower in the PICC group when the analysis was limited to patients for whom the catheter was changed for the first time in the ICU after CVC insertion in the ER with similar indication and catheter insertion times (18.6 vs. 10.3/1,000 catheter-days, respectively, p<0.05). The median duration of catheter use was significantly longer in the PICC group than in the CVC group (16 vs. 6 days, respectively, p<0.05). Conclusions: The study results showed that the duration of catheter use was longer and the infection rate were lower in the PICC group than in the CVC group, suggesting that PICC is a safe and reliable alternative to conventional CVC.

Background/Aims: The optimal systolic blood pressure (SBP) goal for elderly patients with hypertension, especially to reduce cardiovascular disease (CVD) incidence and improve outcome, is unclear. This study aimed to evaluate the beneficial effects of intensive treatment for hypertension on the incidence of CVD in elderly Korean patients. Methods: The HOW to Optimize eLDerly systolic Blood Pressure (HOWOLD-BP) trial is a multicenter, parallel-design, open-label, randomized controlled trial designed to evaluate whether intensive treatment (SBP ≤ 130 mmHg) will provide more benefits in lowering the incidence and mortality associated with CVD than standard treatment (SBP ≤ 140 mmHg) in elderly patients with hypertension aged ≥ 65 years. For this study, eleven university hospitals in Korea will enroll approximately 3,176 elderly patients with hypertension between 2019 and 2022. Patients will be requested to visit the clinic every 4 months for the first year and every 6 months thereafter for 36 months. Parameters, including clinic and home blood pressure, anthropometric and laboratory findings, and frailty assessments, will be collected according to the standardized protocol. The primary outcome is a composite of CVD (acute coronary syndrome, stroke, and heart failure) incidence and cardiovascular deaths. Results: As of December 2021, 1,655 participants had been enrolled in the study, including 831 patients in the standard group and 824 patients in the intensive group. Conclusions: The HOWOLD-BP trial is the first study performed in Korea to evaluate the beneficial effects of intensive blood pressure treatment on CVD in elderly patients with hypertension. The results of this study will help clarify the appropriate target SBP for this population.

( Dong Yeon Ryu ),( Hohyun Kim ),( June Pill Seok ),( Chan Kyu Lee ),( Kwang-hee Yeo ),( Seon-uoo Choi ),( Jae-hun Kim ),( Hyun Min Cho ) 대한외상학회 2019 大韓外傷學會誌 Vol.32 No.2

Purpose: There is increasing interest in intra-abdominal pressure (IAP) and intra-abdominal hypertension (IAH) in critically ill patients. This study investigated the effects and outcomes of elevated IAP in a trauma intensive care unit (ICU) population. Methods: Eleven consecutive critically ill patients admitted to the trauma ICU at Pusan National University Hospital Regional Trauma Center were included in this study. IAP was measured every 8-12 hours (intermittently) for 72 hours. IAP was registered as mean and maximal values per day throughout the study period. IAH was defined as IAP ≥12 mmHg. Abdominal compartment syndrome was defined as IAP ≥20 mmHg plus ≥1 new organ failure. The main outcome measure was in-hospital mortality. Results: According to maximal and mean IAP values, 10 (90.9%) of the patients developed IAH during the study period. The Sequential Organ Failure Assessment (SOFA) score was significantly higher in patients with IAP ≥20 mmHg than in those with IAP <20 mmHg (16 vs. 5, p=0.049). The hospital mortality rate was 27.3%. Patients with a maximum IAP ≥20 mmHg exhibited significantly higher hospital mortality rates (p=0.006). Non-survivors had higher maximum and mean IAP values. Conclusions: Our results suggest that an elevated IAP may be associated with a poor prognosis in critically ill trauma patients.

1930~40년대 申基彦의 在中독립운동

류동연(Ryu, Dong-yeon) 독립기념관 한국독립운동사연구소 2017 한국독립운동사연구 Vol.0 No.58

1930년을 전후로 하여 많은 한인청년들은 중국으로 건너가 독립운동에 참여하게 된다. 이들은 1930년대 중반부터 독립운동의 실무를 맡으며, 한인독립운동진영의 ‘중간간부’로 성장한다. 신기언 역시 그들 중의 한명으로 1920년대 후반 중국으로 건너가 북경과 남경에서 당대의 독립운동가들과 교우하며, 독립운동가로 성장한 인물이다. 따라서 이 글은 신기언의 활동에 초점을 맞춰 1930~40년대 재중한인독립운동 세력의 모습과 특징을 살피고자 했다. 신기언은 경북 의성 출생이며, 중국 국민당이 설립한 중앙정치학교에서 수학했다. 그리고 독립운동에 참여한 이후에는 대한민국임시정부에서 야당이라고 할 수 있는 민족혁명당과 신한민주당에 소속되어 활동했다. 특히 신기언은 임시정부의 단파방송 아나운서와 미주 『독립』의 중경특파원으로서 중국 관내지역에서 민족운동의 소식을 알리고 방향을 제시하는 언론운동을 이어나간 인물이었다. 또한 신기언은 중국 관내지역에서 이른바 ‘제3의 세력’을 만들고자 했던 인물이었다. 비록 ‘제3의 세력’을 얻고자 한 이들의 노력은 실패했지만 한국혁명청년단과 조선민족당 해외전권위원회에서 신기언과 그 외 젊은 한인청년들의 활동을 통해 독립운동 진영 내에 세대갈등이 존재하고 있었음을 확인할 수 있었다. 마지막으로 신기언은 독립운동 중에 ‘군사활동의 강화 및 행동의 통일’을 강조했고, 임시정부에 대해 부정적인 시각을 가진 인물이었다. 신기언의 ‘군사활동 및 행동의 통일’이라는 대명제는 1920년대 후반 한인독립운동가들의 영향을 받은 것으로 보이며, 독립운동 기간 동안 그가 끊임없이 주장했던 내용이다. 특히 ‘행동의 통일’이라는 명제는 신한민주당 창당과 해방 후 민족자주연맹 등의 활동까지 이어지는 것이었다. 이처럼 신기언은 중국 관내지역의 ‘중간간부’로써 ‘군사활동 및 행동의 통일’을 강조하며 자신의 세력을 갖고자 노력한 인물이었다. 비록 그는 자신만의 세력을 얻지 못했지만 그를 통해 한인독립운동의 다양한 모습을 읽을 수 있었다. 또한 그의 언론활동이 중국 관내지역에서 독립운동 방략 중의 하나로써 ‘외교’와 ‘군사’활동 이외에 다양한 독립운동 방략이었다는 것을 알 수 있었다. Many Korean youth went over the China before and after in 1930’s. Their aim placed on Korean Independence. They had participated in parties and groups for Korean Independence, charged of administrative works here, grown up as senior executive. Shin Ki-Un who had been used “Refound Shin” as english name get across China, had a large acquaintance with Korean Independence group in Beijing and Nanking. Through this process, he had also become a senior executive. This paper explored character and actual state on Korean independence group in China during the 1930~40’s by Reound Shin’s activities. He was born in Uiseong county(義城郡), Keong Sang province(慶尙北道), studied at the Central Political Institute(College) established by the Kuomintang Party. After graduated from this institute, had been strived for Korean independence in the Korean National Revolutionary Party and the New Democratic Party. particularly served as a anchor of shortwave broadcasting operating by Koran Provisional Government and correspondent in Chungging, China of Korean Independence Newspaper Company in Los Angeles. Through these press movement, had been informed actuality of Korean independence movement in Main China, proposed new direction for independence movement to Korean-American Society in U.S.A. He loyal to build ‘the third zone(group)’ between nationalist typical to the Provisional Government of Korea and socialist of the Korean Revolutionary Party. These attempt His endeavor was aroused from generation conflict. In order words, The young generation with Refound Shin had obvious distinction about Korean independence movement policy. Their effort failed but had given a fresh impetus to Korean independence movement. He had been sought to reinforce military activity and united action for Korean liberation. His policy line was output by intercourse between Korean Independence crusaders in China during 1920’s late, repulsion toward the Provisional Government for Korea policy which had been taking serious view of diplomatic. He was a strong advocate of military activity reinforcement and united action in his life time. United action particularly had been effort to achieve through the New Democratic Party inauguration before 1945 and National Independence League(民族自主聯盟) after liberation. He had been devotion to form political group for military activity reinforcement and united action in Main China. Though his effort failed and seat himself in the nonmainstream group, had been given his best energies to build new policy for Korean liberation.
