The University of Ulsan was founded on February 19, 1969 as the Ulsan Institute of Technology. The University was promoted to a full-fledged University on March 1, 1985. The university is located in Mugeo-dong, Ulsan, South Korea. The University currently has approximately 10,500 students enrolled.The city of Ulsan has been recognized as the Korean city which was built around the corporate base of the multinational Hyundai conglomerate. Thus, the Hyundai Conglomerate announced its plan to give 40 billion won to assist a variety of university-industry cooperation projects.This corporate relationship has helped turn the University into one of South Korea's top rated institutions for graduate job placement, as well as increasing its reputation more broadly as one of the top private universities outside of Seoul.

The aim of this article is for the necessity of wood culture and urban tectonic as practical strategy in Korea. Architecture is not mere result of physical form or style but culture of the day combined people's wisdom and thought. Therefore, the recovery of wood culture is important for the future of Korean architecture. The Wood culture is defined as common values, knowledge, norms and lifestyle of the social members who prefer to use wood products, and it is expression of hearts for forest, which embodies emotional and physical value, and thus culture of life and furnish are finally included in wood culture. It is very important for architectural identity to make an urban tectonic which is the art of assembling the local materials used in construction for high-level values. There is a couple of practical progressive strategies, which could promote and expand wooden architecture are necessary. The first strategy is wooden architecture of urban commercial housing or multiple housing, and another is to implement infill wall that can increase energy performance of old apartments needed for redevelopment.

Background: Pathologic examinations play an important role in medical services. Until recently, the overall status of pathologic examinations in Korea has not been identified. I conducted a nationwide survey of pathologic examination status using the insurance reimbursements (IRs) dataset from the Health Insurance Review and Assessment Service (HIRA). The aims of this study were to estimate current pathologic examination status in Korea and to provide information for future resource arrangement in the pathology area. Methods: I asked HIRA to provide data on IR requests, including pathologic examinations from 2011 to 2015. Pathologic examination status was investigated according to the following categories: annual statistics, requesting department, type of medical institution, administrative district, and location at which pathologic examinations were performed. Results: Histologic mapping, immunohistochemistry, and cervicovaginal examinations have increased in the last 5 years. Internal medicine, general surgery, obstetrics/gynecology, and urology were the most common medical departments requesting pathologic examinations. The majority of pathologic examinations were frequently performed in tertiary hospitals. About 60.3% of pathologic examinations were requested in medical institutions located in Seoul, Gyeonggi-do, and Busan. More than half of the biopsies and aspiration cytologic examinations were performed using outside services. The mean period between IR requests and 99 percentile IR request completion inspections was 6.2 months. Conclusions: This survey was based on the HIRA dataset, which is one of the largest medical datasets in Korea. The trends of some pathologic examinations were reflected in the policies and needs for detailed diagnosis. The numbers and proportions of pathologic examinations were correlated with the population and medical institutions of the area, as well as patient preference. These data will be helpful for future resource arrangement in the pathology area. © 2017 The Korean Society of Pathologists.

OBJECTIVE: Managing test results is an important issue in hospitals because of the increasing use of point-of-care testing (POCT). Here, we propose a smartphone-based system for automatically managing POCT test results.MATERIALS AND METHODS: We developed the system to provide convenience to the medical staffs. The system recognizes the patient identification or prescription number of the test by reading barcodes and provides a countdown to indicate when the results will be ready. When the countdown in finished, a picture of the test result is transferred to the electronic medical record server using the Health Level 7 protocol. Human immunodeficiency virus (HIV) kits were selected in this research because HIV is a life-threatening infectious virus, especially for the medical staff who treat undiagnosed patients. The performance of the system was verified from a survey of the users.RESULTS: The performance of the system was tested at the emergency room (ER) for 10 months using commercially available POCT kits for detecting HIV. The survey showed that, in total, 80% and 0% of users reported positive or negative feedback, respectively. The staff also reported that the system reduced total processing time by approximately 32 min, in addition to reducing workload.CONCLUSIONS: The developed automated management system was successfully tested at an ER for 10 months. The survey results show that the system is effective and that medical staff members who used the system are satisfied with using the system at the ER.

Herein, we present scanning electron microscopy (SEM) correlated dark-field (DF) scattering studies of single gold nanorods (AuNRs). We demonstrate the effect of refractive index variation of the surrounding medium on the localized surface plasmon resonance (LSPR) linewidth in single AuNRs. The LSPR linewidth remains almost constant while increasing the dielectric constant of the medium, which is further verified by discrete dipole approximation (DDA) calculations. Furthermore, we demonstrate how thiol binding affects the LSPR linewidth of the longitudinal surface plasmon of single AuNRs. The thiol resulted in both a red shift and a strong damping with an increased LSPR linewidth. © 2017 Elsevier B.V.

This study investigates the extensibility of an air-inflated, heavy membrane structure. Based on the linear stress-strain relation, the membrane tube section is modelled mathematically while considering the self-weight and extensibility of the membrane material. The governing equations are expressed in a non-dimensional form, in which the extensibility factor is introduced. Integration of these governing equations results in simultaneous algebraic equations of unknowns at the boundaries. These unknowns can be found iteratively using the solutions from the inextensible problem as an initial guess. Some numerical examples are presented to discuss the effect of the extensibility. © The Author, 2016. Published by Oxford University Press; all rights reserved.

Dermatofibrosarcoma protuberans (DFSP) is a low-grade fibroblastic sarcoma with a superficial location that has been suggested to potentially be a type of mesenchymal stem cell tumor. We studied the expression of various immunomarkers, including putative stem cell markers, in a series of 57 DFSPs including variants, and 12 dermatofibromas (DFs). CD105, a mesenchymal stem cell marker, was weakly expressed in 24 DFSPs, whereas other stem cell markers, including CD133, ALK-1, and Oct3/4, were completely negative in all samples. The expression rates of CD105 and CD34 were significantly higher in DFSP (42% and 93%) than in DF (0% and 17%), and CD10 and D2-40 were significantly lower in DFSP (40% and 3.5%) than in DF (100% and 33%), respectively. CD99, CD117, PDGFB, and PDGFRβ expression was comparable between the groups. CD105 mesenchymal cells were not observed in non-neoplastic dermis. In summary, we did not obtain sufficient immunohistochemical evidence to support the DFSP as a cutaneous mesenchymal stem cell tumor. CD34 alone was the most consistent marker of DFSP, irrespective of its variants. Because CD34 non-neoplastic mesenchymal cells were distributed in a location similar to that of DFSP, we suggest that DFSP might have originated from CD34 mesenchymal cells in the dermis.

The discovery of epidermal growth factor receptor (EGFR) activating mutations in non-small cell lung cancer (NSCLC) and the success story of EGFR tyrosine kinases inhibitors (TKIs) have changed the paradigm of cancer therapy from empirical cytotoxic chemotherapy to molecular-targeted cancer therapy. As a result, EGFR TKI therapy, including gefitinib, erlotinib and afatinib, has become the standard therapy for NSCLC patients with EGFR activating mutation as first-line therapy. However, most patients inevitably progress despite initial dramatic and rapid response to EGFR TKIs and therefore during the last decade, a lot of efforts have been made to identify and overcome various resistance mechanisms. Fortunately, T790M secondary mutation, the main resistance mechanism, can be overcome by newly developed third-generation EGFR TKIs, such as osimertinib, while most combination trials trying to overcome resistance mechanisms other than T790M mutation have failed so far. To make it worse, spatial and temporal tumor heterogeneity and clonal selection or evolution are also identified in EGFR mutant NSCLC tumors. Nevertheless, advance of comprehensive and more sensitive molecular diagnostics and monitoring technology, such as next-generation sequencing and dynamic monitoring technology using circulating biomarker and development of new cancer medicine with different mechanisms from EGFR TKIs, especially immune checkpoint inhibitors, might affect or change the treatment paradigm of EGFR mutant NSCLC in the near future. © 2017 Elsevier Inc.

The acute respiratory distress syndrome (ARDS) is typically manifested by refractory hypoxemia with high mortality. A correct diagnosis is the first step to achieve better outcomes. An early intervention to manage modifiable risk factors of ARDS development and the avoidance of aggravating factors that increase disease severity and progression should be carefully addressed. A management plan is necessary at an early stage of ARDS to determine the level of intensive care. It should be carefully decided which therapeutic measures should be performed depending on the patient's underlying clinical condition. The clinician's considerate prudence is required in decisions of when to apply intensive measures for an ARDS treatment. Mechanical ventilator support should be carefully used depending on the patient's severity and pathological phase. Decreasing inappropriate alveolar strain through a low tidal volume under optimal positive end-expiratory pressure is key for ventilator support in ARDS. The extracorporeal membrane oxygenation applied in the experienced centers seems to improve the survival of patients with severe ARDS. A constellation of physical and psychological problems can develop or persist for up to 5 years in patients with ARDS. Therefore, an early mobilization with rehabilitation, even during an intensive care unit stay, should be seriously considered whenever feasible. Lastly, prevention of aspiration, stress ulcers, deep vein thrombosis, catheter-related infection, overhydration, and heavy sedation is essential to achieve better outcomes in ARDS. © 2017 The Japanese Respiratory Society.

In what’s surely to be one of cultural highlights of the year, world-renowned pianists Tong-Il Han and Helen Lee have been lined up to perform two spectacular classical concerts in Florida. Playing host to the events, which take place on Saturday March 4th at 7pm, and Sunday March 5th, at 3pm, is The Chopin Project® with performances to be held at the Unitarian Universalist Church of Sarasota. It looks certain to be a full house with the concerts’ producer already witnessing demand from local music lovers and aficionados right across the State. Beginning with an all-Chopin solo piano recital by Han on the 4th, and concluding when Han is joined by his wife Helen, for a performance of an all-Schubert programme on the 5th, the weekend event will provide the public with an increasingly rare chance to hear Han, now 75 years old, play some of the most beautiful music ever composed for the piano. Han, a former child prodigy, Juilliard scholar, Leventritt prize winner (probably the most prestigious international competition for classical pianists) and White House pianist for President and Mrs. Kennedy, together with Lee, herself an eminent pianist and educator, was persuaded to perform once again by Frederick Slutsky, the brains behind The Chopin Project®. The Chopin Project®, a global community sharing information, educational, audio and video resources, and producing live concerts and outreach events, focused on the great composer’s works, makes Chopin’s music more accessible to listeners and music students worldwide. And, when Slutsky found out that such celebrated musicians lived nearby, he began working on a series of ideas that has culminated in the scheduled performances as well as a separate student outreach event at Sarasota’s Booker High School on Monday, March 6th where there’ll be a master class, performance and student question and answer session. Slutsky explains: “Han is a compelling figure in my life so I’m really excited that I and others are going to be able to hear him play in such an intimate venue. Not only am I fascinated by his background – being born in what is now North Korea, discovered by a 3-star American General and brought to the US at just 12, before winning his scholarship and then the Leventritt Prize at just 23 – but he is also responsible for some of the best Chopin recordings including his 24 Preludes 4 Ballades and 4 Scherzos.” “Getting to know Han, and his wife Helen, has been a real privilege and I just know that the two concerts we have lined up will be a real treat for those equally as passionate about the music as me. I’m sure the events will captivate everyone who attends from the casual fan, to fledgling music student, or even the most deeply committed Chopin or Schubert scholar. And I hope to be announcing more good news soon as Han and Helen are very interested in some larger outreach events that I’m currently working to produce.” Chopin Project® founder and producer, Slutsky, concludes: “Largely designed as a way to inspire and move the next generation of musicians and concert-goers – the main thrust of our stimulating outreach programs with voluntary associations, conservatory-trained musicians and local schools – these two concerts are being subsidised generously by local business clients, friends, and Chopin Project® patrons, so that students from Sarasota or Manatee County can attend both events free of charge together with one accompanying parent who will also benefit from free admission.” Anyone wanting tickets for these two exceptional Chopin Project® concerts, at the Unitarian Universalist Church of Sarasota, on the 4th and 5th of March, can click here to buy them online or call (800) 838-3006 to speak to a sales agent. Admission costs $30 for adults. Although now winding down commitments after a life of playing, recording and teaching all over the world, Tong-Il Han enjoys an enviable reputation. Not only is his personal story inspirational, but his list of musical credits is almost unparalleled. He has performed with the finest orchestras in the world, among them, in America, the New York Philharmonic, Chicago Symphony, Los Angeles Philharmonic, Cleveland Orchestra, and Detroit Symphony. He has also played with the London Philharmonic, Royal Philharmonic, Scottish National Orchestra, Oslo Philharmonic, Monte Carlo Orchestra, Rotterdam Philharmonic, Polish Radio National Orchestra, Budapest Radio Symphony Orchestra, Seoul Philharmonic Orchestra and Russian National Symphony, among many, many others. In a career spanning well over 50 years, Han has been a prolific recording artist, appeared regularly at many classical summer festivals and worked to improve the talents of young musicians: something he still enjoys doing with local students. He has taught music at Indiana University, Illinois State University, the University of North Texas and Boston University. He also served first as Dean of the College of Music and then as Chair Professor of Music at University of Ulsan in South Korea, as well as Guest Professor at Elisabeth University of Music in Hiroshima, Japan, and he has also taught at Korea’s Suncheon University. He now judges piano competitions worldwide. Helen Lee has studied piano performance with renowned musicians such as Leon Fleisher, Steven Bishop Kovachevich, James Tocco, Michel Block, Pamela Paul, and Vladimir Viardo. She received her Bachelor of Music degree from Indiana University, studying under a full scholarship, and her Master of Music from the University of North Texas, with a Teaching Fellowship. Her concert career covers cities in the USA, Korea, Hong Kong, Japan, Thailand, Singapore and Mexico, including as a guest soloist with the Seoul Juenesse Orchestra, the University of North Texas Orchestra, the Hong Kong Philharmonic Orchestra and Daegu Philharmonic Orchestra. Lee taught as the National Institute of Education in Singapore for 14 years, and Nanyang Technological University for 5 years before her return to Korea in 2009, where she taught at Gwangju University. In addition to her musical career, she is also an award-winning artist having won an international painting competition in 2005 and having had her works shown all over the world.
