  • Buyers are transforming their relations with suppliers. For examples, Instead of playing off dozens or even hundreds of competing suppliers against each other, many firms are finding it more profitable to work closly with only a small number of "partners". If will facilitate a move from single-supplier arrangements("hierachies") to mutiple supplier arrangement("markets") because it reduces the costs of coordination with suppliers. According to this logic, Technological developments which lower the cost of acquiring information about prices and product characteristics in a given market should increase to the nymber of tends to lower coordination costs, it wide adoption should lead to an increase in the number of suppliers for most firms, other things being equal. An efficient merket is defined a one that reduces the numer of intermediaries, or the number of Intermediary steps necessary of market tracsaction. It is true that one can order some products via mail order, which reduces the number of intermediaries and cuts transaction costs further Similary, the growth of a global commerce nerwork such as the internet may futher reduce the number of intermediary steps necessary for trade.

  • CEPA (Comprehensive Economic Partnership Agreement) between India and Korea may vitalize Korean economy more and more. Currently most of Korean firms have entered into manufacturing industries like electronics and automobiles. But only a few Korean companies are trying to penetrate into Indian green industry so this paper suggest how to enter into Indian green industry, especially renewable energy sectors. First, Exporting main shaft, tower-flange and polysilicon products can be considered, as a first step of entry mode. Second, entry mode based on contract like technology licensing, strategic alliance and joint venture establishment can be also one of options. For example, Korean solar energy industry which show more competitiveness than that of Indians should try to make technological licensing on PV modules. In addition to this, they should also try to make joint ventures with right Indian partners and build up 'Solar City' nearby regions like Gurgaon in India where many Korean firms are located. Korean shipbuilding firms like Hyundai Engineering which keep on developing wind turbo engines can also try to make strategic alliance with Indian firms like Suzlon which has strong competitiveness. After that, they should explore Korean and Indian wind sector markets together. Third, brownfield investment can be last and final option as a entry mode as we consider the peculiar characteristics of renewable energy industry. Lastly, Korean government which are rush to indulge into green business should formulate more proper and realistic policies to give big incentives the concerned firms which are trying to open international green market so government should make Korean green firms not to lose good market opportunities related to green industry like renewable energy sectors. Renewable energy sectors are basically regarded as infrastructures so close contact to Indian central government as well as state government will be also required.

  • As R&D cooperation activities with various partners are becoming huge in scale and scope, to achieve successful R&D performance, we need to systematically divide by its characteristics and to stratagemically carry out R&D cooperation activities. In this paper we propose R&D cooperation system between the university and the R&D institute in the geoscience field. The cooperation system can include activities of joint R&D program execution, R&D researcher exchange, R&D infrastructure use, technology commercialization and business exchange. Its system seems to positively affect on R&D performance and when considering the level of innovation as a moderating variable, in the situation of high innovation environment its system is able to positively affect on the R&D performance. For different effects of R&D cooperation activities on individual cooperation performance we can choose proper cooperation activities for R&D cooperation purposes.

  • Introduction: Trastuzumab, an HER2-targeting agents, has shown efficacy in metastatic HER2-positive breast cancer patients. Single-agent clinical trials have evaluated therapeutic regimens using trastuzumab for metastatic breast cancer patients. The aim of our study is to evaluate the efficacy and safety of trastuzumab in combination with chemotherapy or hormone therapy in HER2-positive metastatic breast cancer patients. Methods: A literature research was conducted in PubMed and to identify appropriate studies from relevant reviews. Randomized controlled trials comparing chemotherapy or hormone therapy regimens in combination with trastuzumab were eligible. Dadta on clinical outcomes, including safety, efficacy, and patient characteristics were collected. Results: Seven articles describing five trials were included in our systematic review and meta-analysis. Partners of trastuzumab included in trials were anthracycline, paclitaxel, docetaxel, anastrozole and letrozole. The addition of trastuzumab to chemotherapy improved the overall survival (HR=0.79, 95%CI 0.65-0.96), while to hormone therapy did not (HR=0.85 95%CI 0.56-1.30). All trastuzumab-containing regimens increased cardiac toxicity (RR=3.37, 95%CI 1.26-9.02) and grade III-IV adverse events. Conclusions: Our study supports the addition of trastuzumab to chemotherapy which is effective and tolerated for metastatic breast cancer with HER2+ patients. Of note, more adverse events will occur followed the use of trastuzumab, especially cardiac toxicity, with two treatment regimens.

  • In this study, we attempt to identify factors that influence the performances of Korean firms regarding global R&D cooperation, and to derive policy implications for performance improvement. The hypothetic influential factors include firms' general characteristics, purposes and types of cooperation, technology, partners and their countries, and government support. We categorize the performances of global R&D cooperation into technological, economic, and strategic performance, and analyze the effects of those factors on each of the performances as well as the overall performance. We use a standard tobit model for the overall performance, while using a multivariate tobit model for the other performances to reflect the possible correlations among them. The survey data was collected from 162 Korean firms that had previously conducted or were currently conducting global R&D cooperation.

  • The purpose of this research is to describe the characteristics of "One Book, One Community" reading promotion campaigns in which universities are involved in the U. S. A. Many universities and colleges in various communities participate in "One Book" campaigns in communities as leaders or partners, and promote reading for students on campus through either "One Book, One Campus" or "common reading programs." Universities can contribute a lot to "One Book" campaigns in communities by providing library collection, human resources, and facilities, and especially coordinating programs and events which require subject specialties. Also, they can promote the significance of reading literary classics. "Common reading programs" help freshmen easily adjust to campus life and build the sense of belonging to the "academic community" by reading the same book and talking about it with other members of universities.

  • Compactin and pravastatin are competitive cholesterol biosynthesis inhibitors of 3-hydroxy-3-methylglutaryl-CoA reductase and belong to the statin drugs; however, the latter shows superior pharmacokinetic characteristics. Previously, we reported that the bacterial P450, CYP105D7, from Streptomyces avermitilis can catalyze the hydroxylation of 1-deoxypentalenic acid, diclofenac, and naringenin. Here, we demonstrate that CYP105D7 could also catalyze compactin hydroxylation in vitro. In the presence of both bacterial and cyanobacterial redox partner systems with an NADPH regeneration system, the reaction produced two hydroxylated products, including pravastatin (hydroxylated at the C6 position). The steady-state kinetic parameters were measured using the redox partners of putidaredoxin and its reductase. The $k_m$ and $k_{cat}$ values for compactin were $39.1{\pm}8.8{\mu}M$ and $1.12{\pm}0.09min^{-1}$, respectively. The $k_{cat}/K_m$ value for compactin ($0.029min^{-1}{\cdot}{\mu}M^{-1}$) was lower than that for diclofenac ($0.114min^{-1}{\cdot}{\mu}M^{-1}$). Spectroscopic analysis showed that CYP105D7 binds to compactin with a $K_d$ value of $17.5{\pm}3.6{\mu}M$. Molecular docking analysis was performed to build a possible binding model of compactin. Comparisons of different substrates with CYP105D7 were conclusively illustrated for the first time.

  • To obtain visible and traceable information from the supply chain, HW/SW standards for the EPC global network, which process electronic product code (EPC) data read from Radio frequency identification (RFID) tags, are regarded as the de facto industry standard. Supply chain participants install information service systems and provide logistics information to partners by following the EPCglobal architecture framework. Although quality of service (QoS) is essential for providing dependable and scalable services as pointed out by Auto-ID Lab, only a few models for the performance analysis of QoS-related work have been developed in the context of EPC information service systems. Specifically, doing so allows alternative design choices to be tested in an easy and cost-effective manner and can highlight potential performance problems in designs long before any construction costs are incurred. Thus, in this study we construct a model of an EPC information service system for the purposes of performance analysis and designing a dependable system. We also develop a set of building blocks for analytical performance models. To illustrate how the model works, we determine the characteristics of an EPC information service system and then select a combination of these proven modeling concepts. We construct a performance model that considers the response time and shows how to derive meaningful performance values. Finally, we compare the analytical results to measurements of the EPC information service system.
