The neutral section was installed in order to prevent conflict with different phase angle source in electric railway catenary system. The speed of electric train reduced due to coasting operation by notch off when it passed the neutral section. And, the catenary wire was damaged and the accident might be happened because of the arc generation when the electric train passed the neutral section with notch on condition. This project has a goal to develop the automatic changeover system using by noncontactless semiconductor device in neutral section of catenary system so that the train pass as notch-on condition. In this first year, we obtain as following results such as domestic and international systems applications and completion requirements, development and analysis of stability for automatic changeover system, design of static switching device on automatic changeover system in neutral section and drawing up interface design and specifications according to equipment.

The aim of modern medicine is to prolong life by fighting death. Doctors have traditionally believed that this was an ethical good deed. The negative connotation surrounding death has led to the avoidance of terminally ill patients. But in a modern society where death is medicalized, doctors have to see dying patients every day and are in a state of guilt from implementing meaningless life-sustaining treatments. Therefore, medical schools should allow medical students to embrace a new perspective through death education. Yonsei University Medical College has implemented death education since 2017 as an optional class for first and second year medical students. Students watch videos related to death once a week for 6 weeks and submit their reflections by e-mail. The professor reads the students' reflections and gives them weekly feedback. Through this coursework, students realize that death is not a medical event, but rather a part of life and completion. The ultimate purpose of death education is to transform blind life-absolutist identity into narrative identity.

In the last few years there has been a resurgenceof interest in in-situ saphenous vein arterial bypass for lower extremity revascularization because of improved patency rates. we performed 1 in situ bypass oreration using the intraluminal valve-disruption tecnique. A 65-year-old female who had ztherosclerotic obstruction in the superficial and popliteal arteries underwent in situ saphenous vein arterial bypass. After harvesting of saphenous vein, we used LeMaitre retrograde valvulotome for valve-disruption technique. Completion of the arterrigraphy was performed to evaluate bothh the anastomoses. The two side brances were all ligated. In situ saphenous vein arterial bypass has become the procedure of choice for distal reconstruction in severely ischemic lower extremities because of improved long-term patency compared with reversed-saphenous vein bypass procedure.

This paper deals with the introduction of capstone design project by team activities in Department of Electronics and Communication Engineering, Korea Maritime University. This course is referred to as Creative Engineering Design for spring semester of 4th-year undergraduates. The course focuses on creative thinking and cooperative mind to students by learning engineering design skills, realizing their idea through design project and recognizing practicality of their systems. The intent of the course is to provide a true "capstone" experience, where students can combine their skills to achieve the successful completion of a project. This paper describes class process and evaluation method, and cooperative works with mentees and industrial mentors connected through Hanium network for IT mentoring activities.

Recently, there has been growing interest in Gyongin Line demand estimation, because SMRT(Seoul Metropolitan Rapid Transit Corporation) Line 7 will be extended west by 9.8km from Onsu to meet the Gyongin Line at Bupyeong-gu Office. This study was designed to estimate the change of traffic demand in Gyongin Line before and after the completion year 2011, also provide against the economic loss caused by the derived demand from Gyongin Line to SMRT Line 7. In this paper we give preliminary results for the strategic plans for traffic demand estimation and train operating plan in Gyongin Line by analyzing transport performance of Seoul metropolitan subway, and an additional study on the transportation market and the urban development plan is needed for more accurate results.

This study explored the effectiveness of a hierarchical treatment of aphasic perseveration (TAP) program in a Korean client with transcortical sensory aphasia. The subject with 52% perserveration score (Korean version of Boston Naming Test : K-BNT) was 44 year-old female with MCA (Middle cerebral artery) infarction. The experimental design used was an alternating treatment design with the hierarchical TAP and conventional audio-visual stimulation. The frequency of occurrence of perseverative behaviors and correct response in naming performance were analyzed and compared. It was claimed that the hierarchical TAP was more effective in naming performance than conventional audio-visual stimulation in terms of correct naming response. The frequency of occurrence of perseverative behaviors was lower in hierarchical TAP but the difference was relatively small. Unlike in English, sentence completion task was no longer stimulable while unison speech was very stimulable among the specific strategies of TAP program in Korean. Therefore, it could be said that TAP is language-dependent.

A 38 years old man had been treated as a pulmonary tuberculosis by the positive result of acid fast stain of bronchial washing from the focal infiltrative lesion at left lower lobe. On radiologic examination after one year treatment, there was an aggravation of lesion at left lower lobe with moderate amount of pleural effusion at the same side. After 11 weeks, follow up chest film disclosed bilateral pleural effusion. The pleural fluid of both side was pus in gross appearance with low pH, high LDH, low glucose and high protein. Pleurodectomy was performed to remove the loculated empyema with the thickened pleura of right thorax. This pleuro-pulmonary lesion can be easily misdiagnosed as a tuberculous lesion if it is not taken into consideration as a possible diagnosis.

Early this year the construction of new high voltage power lines have been forced to stop due to the demonstration of residents in Kwa-chun. According to mutual agreement between the residents and Korea Electric Power Corporation, electromagnetic field(EMF) from present power lines was measured and EMF after completion of new power lines was estimated. The results show that EMF near power lines Is relatively low, and EMFnear electric substation is quite high due to the short distance between the power lines and ground. For 4 conduction 345kV line, magnetic field decreases to 3mG at the distance of 50m from the power line.

Massive chylous leakage is a rare postoperative complication that can prolong hospital stay and cause secondary morbidities. Conservative management strategies are the treatment of choice; however, radiation therapy (RT) can be used as an alternative for cases that are refractory to conservative treatment. Herein, we report a 69-year-old female patient who suffered from massive chylous leakage after subtotal gastrectomy. Due to persistent massive chylous leakage, she was scheduled to undergo low-dose RT. Radiation was delivered with a daily dose of 1 Gy, using an anterior-posterior and posterior-anterior beam arrangement. The clinical target volume encompassed the entire lymph node area of the D2 dissection. RT was completed at the total dose of 8 Gy because the amount of chylous leakage declined rapidly. Percutaneous drainage tube was removed after 3 days of RT. The patient did not complain of any symptoms related to massive chylous leakage 2 years after the completion of RT.

Simyak (Finding Herbs) was a medical bureaucracy appointed directly by the central government of the Joseon Dynasty to the province. Simyaksalye (Casebook of Finding Herbs) was a 19th-century manuscript dealing only with Simyak. This study has outlined and analyzed the contents of this document. This article reveal facts which include : 1) The year of completion of this document was after December 24, 1873. However, the contents of the text were mixed with different writing periods in the 19th century. 2) The author of this document was assumed to be a member of Jeonuigam. Jeonuigam-based expressions appear in the content. 3) Simyak's main focus was not on contributing to local health care, but on the procurement of goods for central care. Much of Simyaksalye's content were on medicines and goods facts and their benefits. If Simyak's role was important in local medical cadet education, then there would have been rules related to it.
