Blunt or nonpenetrating chest injuries are common after motor vehicle accidents or falls. Blunt injury to the heart ranges from contusion to rupture. Cardiac rupture, however, is un-common and associated with a very high mortality rate ; left ventricular rupture due to falling is even more rare. We experienced a case of left ventricular rupture of the heart caused by a fall, which the patient survived. A 63-year-old man fell off a ladder and presented with hypotension from left hemothorax and pericardial tamponade. The hemothorax was relieved via an emergency closed thoracostomy but dyspnea and hypotension continued. And so, echocardio-graphy was done and pericardial tamponade was detected. Emergency left thoracotomy was done to repair the rupture site. We believe that patients with cardiac rupture who reach the hospital alive can often be saved by prompt diagnosis and immediate surgical treatment.

purpose: This study was conducted to describe qualitatively the entities of nurse's experiences in general hospitals and to suggest basic data guiding research on developing Standards of clinical nursing practice in Korea. Method: Fourteen nurses working at general hospitals with over 300 beds in Seoul were interviewed in-depth until saturation using tape-recorders and transcription. Result: The central theme of clinical nursing practice experienced by subjects was "being with clients" that means accepting client's personal character, solving client's needs and providing client-centered nursing. A also "being with clients" was felt to be the responsibility of nurses which was learned from their nursing schools. The nursing strategies performed in order to be with patients were proving skillful nursing techniques, accepting, educating, emotional support, advocating, and self-reflecting, the subjects experienced somewhat problematic affects such as difficulties in interpersonal relationship, work overload, negative image of nursing, deficit of self-confidence for nursing actions, poor working conditions, and unfair treatment. Nurses at the hospital practiced with pride when they felt that they were accepted by clients. Conclusion: Further research is needed to analysis problems in clinical practice and the comparison of nurses' experiences of clinical practice, with nurses' experiences in various settings.

Note on B-spline Volume Representation of Measured BRDF Data

Joo-Haeng Lee,Hyungjun Park (사)한국CDE학회 2010 한국CAD/CAM학회 국제학술발표 논문집 Vol.2010 No.8

Digital image synthesis based on light transport simulation has become an indispensable tool for computer graphics applications. Especially for better realism in material appearance, measured bidirectional reflectance distribution function (BRDF) data have been used to accurately represent complex interaction between lights and surface materials. However, large storage requirement for the BRDF data makes it difficult to adopt them in practical rendering applications. In this paper we propose B-spline volume BRDF (BVB) that is a compact and accurate representation of such measured BRDF data of real materials. We present how to construct BVB models from the measured BRDF data, and describe the application of BVB models to photorealistic rendering. Then, we show that the resulting BVB models are compact in model size, effective in preserving the features of material appearance, and suitable for representing the measured BRDF data.

Purpose: The purpose of this study is to compare the perioperative blood loss in primary non-cemented total hip arthroplasty (THA) performed for rapidly destructive coxarthrosis (RDC) with the perioperative blood loss in primary non-cemented THA for typical osteonecrosis of the femoral head (ONFH). Materials and Methods: From January 2000 to December 2013, 19 patients were diagnosed with RDC (group 1) and 40 patients were diagnosed typical Ficat stage IV ONFH (group 2), comparison of perioperative blood loss between group 1 and group 2 in primary noncemented THA was done. Patients with preoperative usage of steroid or anticoagulants medication and with hemodynamic abnormal blood test results were excluded. The blood loss was measured up to the fifth post operation day and calculated with formula proposed by Mercuriali, Inghilleri and Nadler. Results: Non-compensated blood loss calculated in milliliters of red blood cells was 362 mL (standard deviation [SD], 187; range, 77-675) in group 1 and 180 mL (SD, 145; range, 53-519) in group 2. Compensated blood loss was 630 mL (SD, 180; range, 380-760) in group 1 and 503 mL (SD, 260; range, 190-1, 505) in group 2. The total blood loss after primary non-cemented THA is greater when surgery is performed for RDC than for ONFH, with the volume of 992 mL (SD, 300; range, 457-1, 434) in group 1 and 683 mL (SD, 360; range, 226-1, 975) in group 2 respectively. Conclusion: Total perioperative blood loss was significantly greater in RDC than in ONFH in primary noncemented THA.

Geometric shape morphing is a special geometric operation that interpolates two geometric shapes to generate in-between shapes, which can be used in various design applications such as pipe-like surface design or motion simulation in CAD/CAM. It has been well known that Minkowski sum can be used to design collision-free motion path and to modify geometric shapes. Recently, we developed a geometric modeling technique to interactively control geometric shape morphing based on Minkowski sum. The basic idea develops from the linear interpolation on two geometric shapes where the traditional algebraic sum is replaced by Minkowski sum. We extended this scheme into n-th degree B?zier and blossom control with multiple control shapes. In this paper, we introduce mathematical models of the proposed control structure and some of their properties. Moreover, we present a fast and efficient computation method based on direction map analysis, which has been optimized for repeated generation of in-betweens to outperform previous algorithms.

Lee, Jeung Joo,Park, Kee Woong,Kwak, Youn-Sig,Ahn, Jae Young,Jung, Young Hak,Lee, Byung-Hyun,Jeong, Jae Cheol,Lee, Haeng-Soon,Kwak, Sang-Soo Elsevier 2012 Plant science Vol.193 No.-

<P><B>Abstract</B></P> <P>This study compares the differences in proteomes expressed in tuberous roots of a light orange-fleshed sweetpotato (<I>Ipomoea batatas</I> (L.) Lam. cultivar Yulmi) and a purple-fleshed sweetpotato cultivar (Shinjami). More than 370 protein spots were reproducibly detected by two-dimensional gel electrophoresis, in which 35 spots were up-regulated (Yulmi vs. Shinjami) or uniquely expressed (only Yulmi or Shinjami) in either of the two cultivars. Of these 35 protein spots, 23 were expressed in Yulmi and 12 were expressed in Shinjami. These protein spots were analyzed by matrix-assisted laser desorption/ionization-time of flight mass spectrometry and electrospray ionization tandem mass spectrometry. Fifteen proteins in Yulmi and eight proteins in Shinjami were identified from the up-regulated (Yulmi vs. Shinjami) or uniquely expressed (only Yulmi or Shinjami) proteins, respectively. In Yulmi, α-amylase and isomerase precursor–like protein were uniquely expressed or up-regulated and activities of α-amylase, monodehydroascorbate reductase, and dehydroascorbate reductase were higher than in Shinjami. In Shinjami, peroxidase precursor and aldo–keto reductase were uniquely expressed or up-regulated and peroxidase and aldo–keto reductase activities were higher than in Yulmi. PSG-RGH7 uniquely expressed only in Shinjami and the cultivar was evaluated more resistant than Yulmi against the root-knot nematode, <I>Meloidogyne incognita</I> (Kofold and White, 1919) Chitwood 1949 on the basis of shoot and root growth. Egg mass formation was 14.9-fold less in Shinjami than in Yulmi. These results provide important clues that can provide a foundation for sweetpotato proteomics and lead to the characterization of the physiological function of differentially expressed proteins.</P> <P><B>Highlights</B></P> <P>► Proteomics in tuberous roots of two sweetpotato cultivars were compared. ► Over 370 protein spots were reproducibly detected by 2-dimensional electrophoresis. ► Thirty five spots were differentially expressed in either of the two cultivars. ► This study provides new insights to characterize differentially expressed proteins.</P>
