The development of embryos reconstructed by nuclear transfer is dependent upon numerous factors including the type of recipient cell, method of enucleation, the type of donor cell, method of reconstruction, activation, the cell cycle stage of both the donor nucleus and the recipient cytoplasm and the method of culture of the reconstructed embryos. Many of these points which have been reviewed extensively elsewhere (Sun and Moor, 1995; Colman, 1999; Oback and Wells, 2002; Renard et al., 2002; Galli et al., 2003b), here we will concentrate on main area, the production of suitable cytoplast and nuclear donor, nuclear-cytoplasmic coordination, oocyte activation, culture of reconstructed embryos, and the effects that this may have on development.

We study the ballistic spin transport properties in a two-dimensional electron gas system in the presence of magnetic barriers using a transfer matrix method. We concentrate on the size-effect of the magnetic barriers parallel to a two-dimensional electron gas plane. We calculate the transmission probability of the ballistic spin transport in the magnetic barrier structure while varying the width of the magnetic barriers. It is shown that resonant tunneling oscillation is affected by the width and height of the magnetic barriers sensitively as well as by the inter-spacing of the barriers. We also consider the effect of additional electrostatic modulation on the top of the magnetic barriers, which could enhance the current spin polarization. Because all-semiconductor-based devices are free from the resistance mismatch problem, a resonant tunneling structure using the two-dimensional electron gas system with electric-magnetic modulation would play an important role in future spintronics applications. From the results here, we provide information on the physical parameters of a device to produce well-defined spin-polarized current.

In tall building construction, the equipment operation plans have an effect on productivity. Equipment, used in tall building construction, has operating plans of each it and restrictively operate owing to the first placed equipment operation. Therefore the interference of equipment was occur frequently. As it, the productivity is less effective and the construction delay occurs. This research was analysis the interference elements between the equipment for constructing the efficient equipment associated operational processes. The interference elements between the equipment derive through expert advice and analysis using IPA. Through the IPA, this research deducted the interference elements located 'Concentrate Here' which is the highest importance and the lowest performance.

Acquired hemophilia A (AHA) is an uncommon autoimmune bleeding disorder in which autoantibodies that affect the functions of factor VIII (FVIII) are present in the blood. The initial diagnosis of AHA is difficult as the presentations of AHA differ from those of congenital hemophilia A. Moreover, the treatment of AHA is more complex due to the presence of autoantibodies against FVIII. Here, we present a case report of postpartum AHA, to increase the perception and knowledge regarding the recognition and management of such cases. We present a young female with the chief complaint of vaginal bleeding and upper arm ecchymosis. Laboratory results exhibited isolated prolonged activated partial thromboplastin time (APTT) and FVIII inhibitors. The patient was treated with corticosteroids, FVIII concentrates, and a bypassing agent. In conclusion, unexplained postpartum bleeding, unmanageable with basic hemostatic measures, should lead to clinical suspicion of an acquired bleeding disease.

During slaughtering, animal blood is typically discarded, resulting in water pollution. However, this discarded blood has valuable components, such as immunoglobulin (Ig). Although several studies have been conducted to develop methods for effective recycling of slaughterhouse blood, they have not been commercially utilized in Korea. Here, we extracted an Ig-rich fraction from porcine blood that was then subjected to various in vitro tests, including pathogen growth inhibition, antigenic cross-reactivity, and anti-toxin activity. The porcine immunoglobulin concentrate (PIC) was effectively purified by eliminating other components, such as albumin, and consisted of approximately $63.2{\pm}2.9%$ IgG and $7.2{\pm}0.4%$ IgM on a protein basis. The results showed that it significantly suppressed the growth of pathogenic bacteria, and bound to all tested pathogens, including both gram-positive and gram-negative species, although the degree of activity differed according to strain. The PIC bound to two types of lipopolysaccharide (LPS) obtained from Escherichia coli O111:B4 and Salmonella enterica serotype typhimurium in a concentration-dependent manner. In addition, the PIC restored the proliferation activity of the lymphoblast K-562 cells when co-incubated with pathogenic LPS. These results confirm that the PIC prepared in this study is a potentially valuable functional food material or diet supplement as an alternative to antibiotics that can protect animals from pathogenic bacteria.

Purpose: Many clinical trials have shown the effectiveness of platelet releasate on chronic wounds. However, a large volume of blood must be aspirated from a patient and a platelet separator is required. Here, we hypothesized that platelet concentrate obtained from a blood bank (PCBB) would be also effective at stimulating wound healing. The purpose of this study was to investigate the effectiveness of PCBB on accelerating healing of diabetic wounds in vivo. Methods: Round wounds of 5 mm diameter were made at four sites(two wounds on the left and two on the right side) on the backs of nine diabetic mice. Three hundred million platelets suspended in 0.05 ml fibrinogen were dispersed on each wound on left sides. Same amount of fibrinogen without platelets was dispersed on right side control wounds. Thereafter, 0.05 ml thrombin was applied to the each wound. Ten days after wound treatment, healed wounds were excised and the extent of wound healing in each group was compared. Results: Quantitative histologic analysis of epithelial gap distances revealed that PCBB treatment had greatly accelerated wound healing. Mean epithelial gap distances for PCBB treated and control wounds were $2.5{\times}0.6mm\;and\;3.6{\times}0.5mm$, respectively(p<0.05). Conclusion: Our results suggest that PCBB has potential to accelerate the healing of diabetic wounds.

The measurement and management of patient satisfaction has become one of the key issues in the last two decades. Hospitals must thoroughly understand the needs of their customers and design products and health services that meet and exceed their expectations. The importance-performance analysis(IPA) is a widely used analytical technique that yields strategies for managing customer satisfaction in a variety of applications. IP A is a two-dimensional grid based on customer-perceived importance of quality attributes and attribute performance. Depending on the interplay of these two dimensions, four strategies can be derived. The aim of this study is to develop the management strategies for improving patient satisfaction in university hospitals using the I-P analysis. The attributes on inpatient service quality in 4 university hospitals was investigated using the Martilla and James(l977)' s a mean adjusted I-P grid where the axes of the grid cross at the average rating point of all items. The patient satisfaction questionnaires were completed by 600 hospital inpatients. The main statistical methods are path analysis and IPA with SPSS 12.0 and AMOS 4.0 statistical softwares. The two attributes, physician and medical service, administrative staff kindness attributes position in first quadrant(Keep Up the Good domain). The nurse and nursing service attributes position in second quadrant(Possible Overkill domain). The two attributes, convenience of check-in service, facilities and physical environment position in third quadrant(Low Priority domain). Finally the quality of inpatient service(food etc.) attributes position in fourth quadrant(Concentrate Here domain). These findings show various implications on the development of strategies in university hospitals in the future. It was determined that quality of inpatient service(food etc.) need to concentrate more on investments. These investments include a taste, price, proper provision of food service and quick response of pain management. A low priority was given to investment in streamlining the check-in process of inpatient and hospital facilities and physical environment in the long run.
