Writing is a process and work of expressing one's own feelings and thoughts that are not contained in rigid forms; however, the literary trend and environment during the Late Joseon was not so tolerant. A revivalist approach to writing was dominant during this period, which was summarized in the expression that "Prose must be written in the style of Qin and Han; and Poetry in that of High Tang. "Hence, it was practically a taboo to express one's raw emotions and disregard the custom and regulations of writing. Nevertheless, literati, who got tired of the dogmatic rule of Neo-Confucianism at the time that refused to see the changing world and the pseudo-archaic writing that merely imitated the outside and was empty inside, attempted new styles of writing to escape from the model or example and what was familiar. Lee Yong-hyu, who was in the middle of such transformations, learned the trends of Late Ming and Early Qing through the newly imported Chinese books and created his own style that reflected his personality. His writings refused the Neo-Confucian system of thoughts, which was a dominant ideology of the time, paid attention to the human nature and emphasized the restoration of the self. His writing could be described as being anti-pseudo-archaic and criticized the pretentious trend of the time. He argued that in order to restore the true self, one must recover the innocent mind that was bestowed on human by heaven/nature (cheon-li, 天理), and for this purpose, one must straighten out one's mind (sim, 心). His argument is similar to that of "Yangming School of Mind," which could be represented by the phrase, "Mind is the Principle (心卽理)." Yangming School claimed that moral principle existed within one's mind; and this was in stark contrast with the Neo-Confucian idea that "principle (li)"was external and transcendent, and was spoken by the great Confucian masters and written down in Confucian Classics. By denying the externality of the principle and underscoring its immanence, the idea that centralized Confucian Classics and canons was dismantled. Lee Yong-hyu's writing styles that denied the model and emphasized the restoration of the self was influenced by such thoughts. However, one must neither hastily judge that he is an advocate of Yangming School of Mind, nor determine the anti-pseudo-archaic writers' ideological basis as the philosophy of Yangming School. Once it is rigidly defined, be it Zhu Xi's philosophy or Wang Yangming's philosophy, it becomes another model that one must abide by, and again the self disappears. Thus, Lee Yong-hyu defied any kind of model that claimed authenticity or precedence and wished that people would live independently as oneself, and left such claims and wishes in writing. That is the reason, after more than two hundred years later, we still read his writings.

유비쿼터스 건강관리를 가능하게 하는 U-health의 중요성이 부각됨에 따라 다양한 U-health 서비스들이 개발, 제공 되고 있다. 하지만 대부분의 서비스들이 제한적이고 독립적으로 구성되어 있어서 다른 서비스와의 연동을 통한 폭넓은 서비스의 제공이 어렵다. 이러한 서비스 연동을 위해서는 U-health 데이터 및 단위 서비스를 체계적으로 관리하고, 맞춤형 U-health 서비스 개발에 필요한 단위 서비스 검색 방법이 필요하다. 이 논문에서는 온톨로지를 이용하여 U-health 데이터 및 서비스들을 체계적으로 명세하고 관리하기 위한 방법과, 온톨로지 정보를 이용하여 의미적으로 서비스를 검색할 수 있도록 하는 서비스 브로커링 방법을 제안한다. 그리고 이를 활용해 스트레스 관리 U-health 서비스를 구축한 사례를 설명한다.

PV 시뮬레이터는 제한된 공간에서 PCS(Power Conditioning System)의 성능을 평가하거나, 고장유무를 검사하는데 필수적인 장비이다. PV 시뮬레이터가 PV 어레이와 동일한 동작을 하기 위해서는 다양한 재질의 PV cell에 대하여 모델링이 가능해야한다. 본 논문은 EN50530에 규정되어 있는 최대전력운 전범위인 $V_{MPP}{\pm}10%$ 구간에서 발생하는 오차를 다른 PV cell 모델링 알고리즘과 비교하고 제안한 알고리즘의 우수함을 증명하였다.

Retrophayngeal hematomas frequently develop in patients who had cervical vertebra fracture. The hematoma develops in the space between buccopharyngeal fascia and prevertebral fascia. But it rarely causes severe airway obstruction. We recently treated a patient who had dyspnea and dysphagia due to a retropharyngeal hematoma without any significant trauma history. First, tracheostomy was performed to maintain the airway. Then, incision and drainage was done under suspension laryngoscope. This case shows the fact that a retropharyngeal hematoma can result in severe airway obstruction even after a minor trauma.

In this paper, soft switching boost converter with ZVT(Zero Voltage Transition) method was proposed. Each switch of the proposed ZVT converter is operated under soft switching condition through using auxiliary resonant circuit. Also, the ZVT converter is verified through operation modes analysis and simulation.

This paper describes the development of training simulator for Hadong fossil Power Plant. The simulator was developed to train operator, test new control Logic and evaluate alternative operating procedure for expert engineer of control system. The most control logics such as Siemens TELEPERM ME and GE Mark V are translated directly from microprocessors. Those HMI are also directly emulated. The simulation was performed by ProTRAX modeling software. The paper discusses the configuration of simulator and the simulation results of 30%, 50%, 75% and 100% normal rate load test.

The Operational Deflection Shape designates the motion pattern by which a structure vibrates under a specific operating condition. Modal Analysis is usually tested under test bench, but Operational Deflection Shape can be measured directly under real operating condition. It provide useful information for trouble-shooting and aid understanding and evaluation of the absolute dynamic behaviour of a machine or component. In this paper, It is analysed Excavator Upper Frame using Operating Deflection Shape.
