Left ventricular free wall rupture following acute myocardial infarction (AMI) is the second most common cause of death and has been reported to be responsible for 4 to 24% of all infarction deaths. The rupture occurs anywhere from a few hours to several days after AMI. The common findings of ventricular rupture are persistent chest pain bradycardia and shock. This may be often mistaken for the ruptured dissection of the ascending aorta. The different points from dissection are 1) persistent chest pain 2)persistent ST segment elevation and 3) only intramural hematoma in ascending aorta. We have sucessfully managed two patients with postinfarction myocardial rupture. Surgical management consisted of infarctectomy repairi of the ventricular rupture and coronay artery bypass grafting. We conclude that successful surgical management of ventricular free wall rupture should require prompt diagnosis and emergency operation.

Endoscopic sympathicotomy is the choice of the treatment for hyperhidrosis. There are some recognized risks such as Honer's syndrome and Hemopneumothorax; however, Chylothorax has very rarely been reported after thoracic sympathicotomy. We recently encountered a case of chylothorax. Early diagnosis and prompt treatment is noteworthy.

Patients with concomitant surgical diseases of the heart and lungs are a therapeutic challenge to cardiothoracic surgeons. A 59-year-old woman underwent right middle lobectomy for lung cancer and redo double valve replacement with tricuspid annuloplasty simultaneously. Concomitant operation is a safe procedure and might allow prompt correction of both conditions, thereby sparing the patient a second major thoracic procedure with its attendant risks.

Development of intraoperative aortic dissection during coronary artery bypass surgery is extremely rare with catastrophic outcomes resulting in high rates of morbidity and mortality. The prognosis is highly dependant upon prompt diagnosis and emergent treatment. We report our experience on a 72 year old female patient who successfully received ascending aortic graft replacement for acute intraoperative aortic dissection during coronary artery bypass procedure.

GW170817/GRB170817A establishes a double neutron star merger as the progenitor of a short gamma-ray burst, starting 1.7 s post-coalescence. GRB170817A represents prompt or continuous emission from a newly formed hyper-massive neutron star or black hole. We report on a deep search for broadband extended gravitational-wave emission in spectrograms up to 700 Hz of LIGO O2 data covering this event produced by butterfly filtering comprising a bank of templates of 0.5 s. A detailed discussion is given of signal-to-noise ratios in image analysis of spectrograms and confidence levels of candidate features. This new pipeline is realized by heterogeneous computing with modern graphics processor units (GPUs). (Based on van Putten, M.H.PM., 2017, PTEP, 093F01.)

Although it is agreed that the gamma-ray bursts (GRBs) invoke highly relativistic jets with bulk Lorentz factors of a few hundreds, the exact physical mechanism producing such powerful gamma-rays still remains debated. Three outstanding and important questions in the field concern (1) the composition of GRB jets (i.e., matter-dominated vs Poynting-flux-dominated), (2) the involved radiative process responsible for the observed gamma-rays (i.e., synchrotron mechanism vs photospheric radiation), and (3) the distance of the emitting region from the central engine where the prompt gamma-rays are released (i.e., ~10^12 cm vs 10^14 cm vs 10^16 cm). I will present recent important breakthroughs that we have made, which answer these three questions.

Recently, Because the consumption of electricity is increased, having stable electricity supply and diagnosis of the power device is important. In this paper, I propose a diagnostic techniques of the leakage current for switchgear based on LabVIEW NI's. Using the data obtained from the leakage current sensor installed in switchgear panels, in performed continuously diagnosis, notifications and warnings can be the administrator immediately results. It is expected accordingly, the administrator will be able to take prompt action. Using the virtual switchgear with a PXI NI's, war tested the proposed techniques.

This study aims to examine the relative importance of various tasks of EMT and to examine knowledge level and problems associated with AED. It is based on the survey of paramedics and 119 rescures. The results for this study were as follows ; Among the tasks of EMT, 'foreignbody removal from mouth' were rated as the most important, followed by '$O_2$ supply', 'CPR', 'Intubation for CPR', '$O_2$ supply' were rates as the most necessary, followed by 'foreignbody removal from mouth', 'external bleeding control'. In terms of the knowledge level about AED, survey respondents are most knowledgeable about 'role of other rescures during the preparation for AED' and 'treatment after 3 AEDS. The most important reason that the uses of AED is delayed is 'unclear boundary of treatment directed by medical control'. The results of the study suggest that we need guideline for EMT's tasks, efficient communication system between 119 and emergency health are center for prompt AED, and training and education program for AED.

To meet increased demand and lead to execution of successful overseas's plant construction, A prompt System is urgently needed to carries prevention and control of hazards associated with work related tasks and activities. This study is aimed to develop efficient and reliable safety management program to identify control measures for high risk activities by choosing and conducting proper risk assessment methodology that addresses Risk Priority Number(RPN) of adverse effects.
