The purpose of the paper is to examine sidedness effects of comparative advertising and moderating roles of the emotions of customer and product type. To test the research hypotheses, this study conducted experimental designs. One hundred ninety-two undergraduate students were assigned to one of the four experimental groups. Comparative Advertising message type and product type were manipulated as between-subject factors. There was a surprising event situation(free gift event) when participants came to laboratory for experiment, which is for the emotion manipulation. If a participant in a positive emotion group, he or she gets a free gift. The data demonstrate that comparative message type have a significant effect on both attitude toward the advertising and acceptance intention. In addition, consumers' emotion and product type play a significant moderating role between the message types and the dependent variables. The results of this study contribute to the literature as a new attempt to examine the sidedness effect of the comparative advertising message. We suggested that message types and consumer's emotion is one of very important aspects for a comparative advertising and marketers should consider people's emotion when they release a comparative advertising, which can help when marketers make their strategy for a comparative advertising.

Over the years, nanoparticle drug delivery systems have demonstrated versatile potentials in biological, medical and pharmaceutical applications. In the pharmaceutical industry nanotechnology research has mainly focused on providing controlled drug release, targeting their delivery to specific organs, and developing parenteral formulations for poorly water soluble drugs to improve their bioavailability. Achievement in polymer industry has generated numerous polymers applicable to designing nanoparticles. From viewpoints of product development, a nanocarrier material should meet requirements for biodegradability, biocompatibility, availability, and regulatory approval crieteria. Albumin is indeed a material that fulfills such requirements. Also, the commercialization of a first albumin-bound paclitaxel nanoparticle product (Abraxane$^{TM}$) has sparked renewed interests in the application of albumin in the development of nanoparticle formulations. This paper reviews the intrinsic properties of albumin, its suitability as a nanocarrier material, and albumin-based parenteral formulation approaches. Particularly discussed in detail are albumin-based particulate injectables such as Abraxane$^{TM}$. Information on key roles of albumin in the nab$^{TM}$ technology and representative manufacturing processes of albumin particulate products are provided. It is likely that albumin-based particulate technology would extend its applications in delivering drugs, polypeptides, proteins, vaccines, nucleic acids, and genes.

Solid lipid nanoparticles (SLNs) have emerged to combine the advantages of polymeric nanoparticles and lipid emulsions in early 1990s. SLNs can present several desirable properties derived from the solid state core. When formulating SLNs, there should be careful considerations about the physical state of the inner solid lipid core and its polymorphism and supercooling behavior. In this review, SLNs were compared to lipid emulsion and emulsion of supercooled melt to understand the unusual behaviors compared to lipid emulsions and to have insights into stability and release mechanism. SLNs have been regarded as biocompatible system because lipids are usually well-tolerable ingredients than polymers. Several studies showed good tolerability of SLNs in terms of cytotoxicity and hemolysis. Similar to various other nanoparticulate drug delivery systems, SLNs can also change biodistribution of the incorporated drugs in a way to enhance therapeutic effect. Most of all, large scale production of SLNs was extablished wihtout using organic solvents. Although there is no SLN product in the market till date, several advantagious properties of SLNs and the progress we have seen so far would make commercial product of SLNs possible before long and encourage research community to apply SLN-based formulations for water-insoluble drugs.

In engineering industry, technical documentation refers to any type of documentation that describes handling, functionality and architecture of a technical product. The intended audiences for product technical documentation is the end user, the administrator, service or maintenance technician. Competition and rapid technological evolutions have created pressure to release new and improved products on an increasingly frequent basis. As the technical capabilities of products advance, the technical documentation for those products is becoming longer and complex. The Darwin Information Typing Architecture (DITA) is and XML-based, end-to-end architecture for authoring, producing, and delivering technical documents. DITA is an OASIS standard that allows documentation groups to single-source document for multiple products and users, to automatically publish that documentation in several media formats including PDF and HTML, and to efficiently maintain and update that documentation. This paper study on the various implementation projects for technical documentation using OASIS DITA standard and examines the potential for using DITA as a solution for reconstructing existing technical documentation. Also We offer an incremental adoption approach to effectively implement DITA standard of technical documentation project for domestic firms, while reducing failures.

When $^{14}C-2$, 6-Diethylaniline (2, 6-DEA) was incubated aerobically in soil, $^{14}CO_2$ evolved from non-sterile soil A and B was 6.5 and 10.1%, respectively, in the 21st week. Methanol could extract 3.1 and 13.5% of the radioactivity from soil A and B, respectively, 2, 6-Diethylacetanilide was detected as a degradation product in soil. Chaetomium globosum produced 2, 6-diethyl-p-benzoquinone as a degradation product in pure culture. A possible pathway was proposed to include p-hydroxylation of 2, 6-DEA, formation of quinoneimine, and the subsequent hydrolysis with the release of ammonia.

In casting steels for offshore construction, manufacturing integral casted structures to prevent fatigue cracks in the stress raisers is superior to using welded structures. Here, mold design and casting analysis were conducted for integral casting steel. The laminar flow of molten metal was analyzed and distributions of hot spots and porosities were studied. A prototype was subsequently produced, and air vents were designed to improve the surface defects caused by the release of gas. A radiographic test revealed no internal defects inside the casted steel. Evaluating the chemical and mechanical properties of specimens sampled from the product revealed that target values were quantitatively satisfied. To assess weldability in consideration of repair welding, the product was machined with grooves and welded, after which the mechanical properties of hardness as well as tensile, impact, and bending strengths were evaluated. No substantive differences were found in the mechanical properties before and after welding.

A steam generator tube rupture accompanying a core damage may cause the fission product to be released to environment bypassing the containment. In such an accident, the steam generator is the major path of the radioactive aerosol release. AEOLUS facility, the scaled-down model of Korean type steam generator, was built to examine the aerosol removal in the steam generator during the steam generator tube rupture accident. Integral and separate effect tests were performed with the facility for the dry and flooded conditions, and the decontamination factors were presented for different tube configurations and submergences. The dry test results were compared with the existing test results and with the analyses to investigate the aerosol retention physics by the tube bundle, with respect to the particle size and the bundle geometry. In the flooded tests, the effect of submergence were shown and the retention in the jet injection region were presented with respect to the Stokes number. The test results are planned to be used to constitute the aerosol retention model, specifically applicable for the analysis of the steam generator tube rupture accident in Korean nuclear power plants to evaluate realistic fission product behavior.

Radioactive iodine is a representative fission product to be quantified for the safety assessment of nuclear facilities. In integral severe accident analysis codes, the iodine behavior is usually described by a multi-physical model of iodine chemistry in aqueous phase under radiation field and mass transfer through gas-liquid interface. The focus of studies on iodine source term evaluations using the combination approach is usually put on the chemical aspect, but each contribution to the iodine amount released to the environment has not been decomposed so far. In this study, we attempted the decomposition by revising the two-film theory of molecular-iodine mass transfer. The model involves an effective overall mass transfer coefficient to consider the iodine chemistry. The decomposition was performed by regarding the coefficient as a product of two functions of pH and the overall mass transfer coefficient for molecular iodine. The procedure was applied to the EPICUR experiment and suppression chamber in BWR.
