Operation Method for Hybrid UPS with Energy Storage System Function

오진홍,이정훈,류제창,이홍원,채홍문,김재언 대한전기학회 2019 Journal of Electrical Engineering & Technology Vol.14 No.5

With the increasingly widespread use of modern communication systems, advanced medical equipment, advanced living facilities, and emergency systems requiring high-quality energy, there is an increasing need for reliable, efficient, and uninterrupted electricity supplies. Consequently, Uninterruptible Power Supplies (UPS) have recently experienced growing demand. However, because the stored energy of a UPS battery is only used in emergency situations, the battery utilization rate of a UPS is very low. Therefore, a hybrid UPS that integrates an Energy Storage System (ESS) with a UPS has recently been developed. Unlike the conventional UPS, this hybrid UPS can increase the battery utilization rate by using the stored energy of the battery when the grid is under normal operation. However, when a grid fault occurs, the hybrid UPS has to supply emergency power to critical loads. Therefore, transient voltage across the DC-link that could affect the power quality of critical loads can occur during mode transition. This paper proposes the operation method of a hybrid UPS with ESS function to minimize the transient voltage across the DC-link. PSCAD/EMTDC software is used to verify the validity of the proposed operation method.

The specific cutaneous lesions of acute myeloblastic leukemia was described, in which the skin lesions were the initial sign of the leukernia and the performance of the bone marrow aspiration led to correct diagnosis. A 55 year old man had admitted to our hospital with complaints of multiple nodules and tumors on the skin. Four month prior to admission, he had noticed small papules on his back. These lesions become nodular, increased in size and number. And then spread to anterior chest, extremities and face. Skin biopsy specimen showed diffuse dermal and subcutaneous infiltration of abnormal cells that appeared to be leukemic cell in nature. Bone marrow biopsy specimen showed changes of acute myeloblastic leukemia. Treatment was initiated with combined chemotherapy (cytosine arabinoside and adriamycin) and the eruption began to fade away.

Analysis of the internal state of the blast furnace is needed to predict and control the operating condition. Especially, it is important to develop modeling of blast furnace for predicting cohesive zone because shape of cohesive zone influences on overall operating condition of blast furnace such as gas flow, temperature distribution and chemical reactions. Because many previous blast furnace models assumed cohesive zone to be fixed, they can't evaluate change of cohesive zone shape by operation condition such as PCR, blast condition and production rate. Int his study, an axi-symmetric 2-dimensional steady state model is proposed to simulate blast furnace process using the general purpose-simulation code. And Porous media is assumed for the gas flow and the potential flow for the solid flow. Velocity, pressure and temperature distribution for gas and solid are displayed as the simulation results. The cohesive zones are figured in 3 different operating conditions.

Mobile Robot Localization Based on Hexagon Distributed Repeated Color Patches in Unlimited Indoor Area

진홍신,김형석,왕실,서범수 제어로봇시스템학회 2008 제어로봇시스템학회 합동학술대회 논문집 Vol.2008 No.12

This paper presents a new mobile robot localization method for indoor robot navigation. The method uses hexagon distributed color-coded patches on the ceiling and a camera is installed on the robot facing the ceiling to recognize these patches. The proposed icell-coded mapi, with the use of only seven different kinds of color-coded landmarks distributed in hexagonal way, helps reduce the complexity of the landmark structure and the error of landmark recognition. This technique is applicable for navigation in an unlimited size of indoor space. The structure of the landmarks and the recognition method are introduced. And 2 rigid rules are also used to ensure the correctness of the recognition. Experimental results prove that the method is useful.

진홍기 ( Hong-ki Jin ),김형민 ( Hyoung Min Kim ),오용승 ( Yong Seung Oh ),김지훈 ( Jihoon Kim ) 대한골절학회 2021 대한골절학회지 Vol.34 No.1

목적: 중수골 기저부 및 경부 골절의 치료에서 K-강선 staple 고정술의 방사선학적 및 임상적 결과를 알아보고자 하였다. 대상 및 방법: 2016년 11월부터 2017년 5월까지 도수정복이 제한되는 중수골 기저부 및 경부의 불안정 골절을 최소절개를 통한 개방적 정복 후 K-강선 staple로 고정한 13예(10명)의 방사선학적 및 임상적 결과를 후향적으로 분석하였다. 결과: 각 골절에 평균 2.6개의 staple로 고정하였고 각형성은 술 전 36.3도에서 술 후 3.1도로 교정되었다. 술 후 1주에 능동관절운동을 시작한 뒤 방사선학적 골유합은 5.1주에 확인하였고 7.4주에 정상운동범위를 회복하였다. Staple은 16.5주에 제거하였고 치료기간은 18.6주 소요되었다. 최종 추시(27.3주)에서 운동범위와 파악력은 건측과 차이 없이 회복되었다. 변형, 신경손상, 감염 등의 합병증 없이 전 예에서 골유합을 관찰하였고 환자평가에서 외관과 기능상 모두 만족할 만한 결과를 얻을 수 있었다. 결론: 중 수골 기저부 및 경부의 불안정 골절에서 K-강선 staple을 이용한 고정술은 최소 절개와 견고한 내고정을 통해 조기 관절운동이 가능하며 수술 후 관절 강직을 방지하고 치료기간을 줄일 수 있는 효과적인 치료방법으로 생각된다. Purpose: This study was designed to evaluate the radiological and clinical outcomes of a new surgical technique―customized staple fixation using K-wire―in displaced metacarpal neck or base fractures. Materials and Methods: From November 2016 to May 2017, 13 unstable metacarpal neck and base fractures (10 patients) were treated with II-shaped customized K-wire staples fixation, after performing open reductions through minimal dorsal incisions. The radiological and clinical outcomes were retrospectively evaluated. Results: A mean of 2.6 staples were used for each fracture fixation. Preoperative angulation of 36.3° was reduced to 3.1° postoperatively. A week after surgery, the volar short arm splint was replaced with a dorsal splint to initiate active range of motion exercise, and the splint was subsequently removed after 3 weeks. The radiologic union was achieved at a mean of 5.1 weeks, and total active motion was recovered at a mean of 7.4 weeks. On a mean, K-wire staples were removed at 16.5 weeks after the surgery, and the mean treatment took 18.6 weeks. At the final follow-up (at mean 27.3 weeks), no significant difference was observed for total active motion of the digits and grip strength, when compared to the contralateral hand. Complete union was achieved in all fractures without deformity, or complications such as infection or nerve injury. All patients were satisfied with the cosmetic and functional outcomes. Conclusion: K-wire stapling is an effective alternative modality in treating unstable displaced metacarpal neck or base fractures. It requires minimal incision to enable open reduction. In addition, early mobilization is ensured through the rigid fixations. Moreover, it prevents postoperative joint stiffness and reduces the time needed for treatment.

The United Nations Convention on Contracts for the International Sale of Goods(‘CISG’), which more than 80 countries entered as Member States, became into enforcement in Korea on March 1, 2005. This means that the CISG is the international legal regime regulating Korean enterprises who trade with foreign companies. There are several prominent provisions in the CISG, setting up basic norms for the international trade such as ‘remedy’, ‘monetary damages’, ‘specific performance’, and ‘contract avoidance’. The provisions relating to the ‘contract avoidance’ are the most important ones in relation to mutual conflicts between the contracting parties. The general provision regulating the ‘contract avoidance’ is the CISG 25. However among its wording, ‘fundamental breach’ is not only controversial, inviting thorough exploration, but also arouses further investigation for its application to the specific international sale of goods trade. However, developed countries such as Germany and Japan have recently revised their Contract Law according to the CISG regimes in terms of contract cancellation (avoidance). Tracing back to the birth of the ‘contract avoidance’ regimes in the CISG, the relevant wording had been introduced and employed by the case laws in the Anglo-American law. Furthermore, the CISG provides independently several requirements(conditions) to apply the CISG 25 and declare contract avoidance; ‘substantial detriment test’ and ‘the foreseeability component’. In addition, the CISG provides procedural regulations relating to the serving notice of avoidance and allows sellers to fix the performance as the preconditions for the buyers to declare ‘the contract avoided’, even though a aggrieving party(seller) committed the fundamental breach of the contract. In this context, this essay examines and explores various regimes with regard to the contract cancellation(avoidance) and tries to find out the solution for the exact meaning of the wording in the CISG. And it maneuvered the Civil and the Common law regimes in terms of contract avoidance. Finally, it suggests the revision of the Korean Civil Code relating to the contract cancellation(avoidance) according to the relevant CISG provisions. 우리나라가 가입하여 2005년 3월 1일부터 발효된 CISG는 국제물품매매에 있어서 중요한 준거법이 되었다. CISG에서 중요한 규정들은 금전 손해배상, 특정이행 그리고 계약무효와 같이 피해자를 구제하기 위해 두어진 것들이다. 특히, CISG 제 49조와 제 64조에 의하면, 계약 당사자는 일정한 경우에 이미 체결된 ‘계약이 무효라고 선언할 수 있다’고 규정하고 있는데, 이러한 계약해소의 효과는 대륙법계의 ‘소급효’가 부여된 엄격한 의미에서의 원상회복은 아닌 것으로 보인다. 왜냐하면 CISG는 영미법계의 계약해소 법리의 영향도 받았기 때문이다. 한편, CISG 제 25조에서 말하는 ‘계약을 무효로 하는’ 효과가 발생하는 사건으로 들고 있는 계약의 ‘본질적(중대한) 위반’이라는 사고의 틀은 1950년대 영국계약법에서 비롯되었지만, 그럼에도 불구하고 CISG는 여기에 경도되지 않고 CISG만의 독자적인 구조를 가지고 있다. 즉, CISG는 ‘손해’를 입은 당사자의 ‘계약상 및 예상이익’이라는 개념에 바탕을 두고, 그가 입은 ‘손해’라는 관점에서 ‘계약의 본질적 위반’을 정의하고 있다. 아울러 CISG는, 대륙법계인 독일의 유예기간주의 법리에 영향을 받아 계약을 위반한 당사자에게 계약을 이행할 수 있도록 합리적인 기간을 추가로 주어야만 비로소 계약을 무효로 할 수 있도록 하는 부가기간설정 제도도 두고 있다. 위와 같은 CISG의 ‘계약의 본질적 위반’을 중심으로 한 계약해소법리(구조)는 국제상사계약원칙, 유럽계약법원칙은 물론이고 독일민법과 일본민법의 개정에도 큰 영향을 미쳤다. 그렇다면 우리도 CISG의 계약해소 구조(법리)를 우리 법제에 맞게 받아들여, 대륙법적인 채무불이행의 유형에 집착하지 않고 또, ‘채권·채무’의 차원으로부터 한 단계 높여 영미법적인 ‘계약’이라는 큰 틀에서 접근하여 계약법을 논의하는 것이 바람직하다.
