  • This study investigates intents of acquisitions in information technology industries. Mergers and acquisitions are a strategic decision at corporate-level and have been an important tool for a firm to grow. Plenty of firms in information technology industries have acquired startups to increase production efficiency, expand customer base, or improve quality over the last decades. For example, Google has made about 200 acquisitions since 2001, Cisco has acquired about 210 firms since 1993, Oracle has made about 125 acquisitions since 1994, and Microsoft has acquired about 200 firms since 1987. Although there have been many existing papers that theoretically study intents or motivations of acquisitions, there are limited papers that empirically investigate them mainly because it is challenging to measure and quantify intents of M&As. This study examines the intent of acquisitions by measuring specific intents for M&A transactions. Using our measures of acquisition intents, we compare the intents by four acquisition types: (1) the acquisition where a hardware firm acquires a hardware firm, (2) the acquisition where a hardware firm acquires a software/IT service firm, (3) the acquisition where a software/IT service firm acquires a hardware firm, and (4) the acquisition where a software /IT service firm acquires a software/IT service firm. We presume that there are difference in reasons why a hardware firm acquires another hardware firm, why a hardware firm acquires a software firm, why a software/IT service firm acquires a hardware firm, and why a software/IT service firm acquires another software/IT service firm. Using data of the M&As in US IT industries, we identified major intents of the M&As. The acquisition intents are identified based on the press release of M&A announcements and measured with four categories. First, an acquirer may have intents of cost saving in operations by sharing common resources between the acquirer and the target. The cost saving can accrue from economies of scope and scale. Second, an acquirer may have intents of product enhancement/development. Knowledge and skills transferred from the target may enable the acquirer to enhance the product quality or to expand product lines. Third, an acquirer may have intents of gain additional customer base to expand the market, to penetrate the market, or to enter a foreign market. Fourth, a firm may acquire a target with intents of expanding customer channels. By complementing existing channel to the customer, the firm can increase its revenue. Our results show that acquirers have had intents of cost saving more in acquisitions between hardware companies than in acquisitions between software companies. Hardware firms are more likely to acquire with intents of product enhancement or development than software firms. Overall, the intent of product enhancement/development is the most frequent intent in all of the four acquisition types, and the intent of customer base expansion is the second. We also analyze our data with the classification of production-side intents and customer-side intents, which is based on activities of the value chain of a firm. Intents of cost saving operations and those of product enhancement/development can be viewed as production-side intents and intents of customer base expansion and those of expanding customer channels can be viewed as customer-side intents. Our analysis shows that the ratio between the number of customer-side intents and that of production-side intents is higher in acquisitions where a software firm is an acquirer than in the acquisitions where a hardware firm is an acquirer. This study can contribute to IS literature. First, this study provides insights in understanding M&As in IT industries by answering for question of why an IT firm intends to another IT firm. Second, this study also provides distribution of acquisition intents for acquisition types.

  • This paper aims to provide reference model for directions and objectives of Software(SW) gifted education. In order to achieve the goals introduced above, we conducted the research in the following steps. First, we selected the concept of ICT-based creative talented person as a base model to establish the concept of SW gifted person. The selected base model composed three core competencies which were 'knowledge and technology competencies', 'synthesizing and creativity competencies', and 'personality competencies'. Second, we developed survey tools, like questionnaires, to investigate participant's recognition of SW gifted person. The survey tools composed three components 'computational thinking', 'entrepreneurship', and 'social responsibility'. Each of the components composed seven elements. Third, after selecting the opinion poll participants as an elementary school teacher, we surveyed opinion polling. By selecting an elementary school teacher as the opinion poll participants, we wanted to identify theirs ' opinions which are thought to be the starting point for gifted education. To survey we developed on-line survey system by using Google functions. Fourth, we analyzed the collected opinion data. To identify we summarized and synthesized participant's opinions that average values and agreement level by using frequency analysis. Also, in order to compare opinions that average values and agreement level based on whether or not participant's various experiences and competencies we computed t-value, F-value, and ${\chi}^2$ verification.

  • Under the concept of global economy, the enterprises are assigning design and production environments around the world in different areas. A serious problem of information exchange emerges as companies use traditional hardware and very distinct softwares appropriate to their field of expertise. To overcome the decreased productivity due to the interruption of information, the concept of simultaneous engineering and concurrent design becomes very significant. In this article, an agent-based ship design system is developed in order to support a cooperation in distributed ship design environments. Above all, the conflicts that occur in the middle of knowledge sharing in the system must be resolved. An approach to do this is the case-based conflict resolution strategy formulated to resolve current conflict on the basis of previous resolved similar cases in agent-based collaborative design system environments. To do this conflict cases that occur in initial ship design stage are extracted. On the basis of the extracted cases, case-base is constructed. In addition conflict resolution handler located in the facilitator is developed to treat conflict problems effectively by reasoning of the case-base and thus presenting an appropriate solution. The validation of developed case-based conflict resolution strategy is evaluated by applying to collaborative design process in initial ship design stage, especially the machinery outfitting design, the preliminary design, the hullform design, and the structural design. Through the help of the cooperation of the design agents, the facilitator, the conflict resolution handler, and the case-based system, a designer can be supported effectively in his/her decision-making based on the previous cases resolved similarly.

  • Inference engine that performs the brain of software agent in next generation's web with various standards based on standard language of the web, XML has to understand SWRL (Semantic Web Rule Language) that is a language to express the rule in the Semantic Web. In this research, we want to develop a forward inference engine, SMART-F (SeMantic web Agent Reasoning Tools-Forward chaining inference engine) that uses SWRL as a rule express method, and OWL as a fact express method. In the traditional inference field, the Rete algorithm that improves effectiveness of forward rule inference by converting if-then rules to network structure is often used for forward inference. To apply this to the Semantic Web, we analyze the required functions for the SWRL-based forward inference, and design the forward inference algorithm that reflects required functions of next generation's Semantic Web deducted by Rete algorithm. And then, to secure each platform's independence and portability in the ubiquitous environment and overcome the gap of performance, we developed management tool of fact and rule base and forward inference engine. This is compatible with fact and rule base of SMART-B that was developed. So, this maximizes a practical use of knowledge in the next generation's Web environment.

  • The ability to judge a country's scientific standing is vital for the governments and businesses that must decide scientific priorities and funding. In this paper, we analyze the output and outcomes from research investment over the recent years, to measure the quality of scientific research on national scales and to set it in an international context. There are many ways to evaluate the quality of scientific research, but few have proved satisfactory. To measure the quantity and quality of science in different nations, we analyzed the numbers of published research papers and their citations. The number of citations per paper is a useful measure of the impact of a nation's research output. Essential at a were acquired from SCI database by Thomson Scientific, which indexes more than 8,000 journals, representing most significant materials in science and engineering. The purpose of this paper is to evaluate and compare the output and outcomes among nations in a variety of viewpoints and criteria. One of the implications in response to the result of analysis is that sustainable economic development in highly competitive world markets requires a direct engagement in the generation of knowledge. Even modest improvement in healthcare, clean water, sanitation, food, and transport need capabilities in engineering, technology, and medicine beyond many countries' reach. Nations exporting natural resources such as gold and oil can import technology and expertise, but only until these resources are exhausted. For them, sustainability should imply investment in alternative agricultural and technological capabilities through improvements in their skills base. A strong science base does not necessarily leat to wealth generation. However, strength in science has additional benefits for individual nations, and for the world as a whole.

  • This study analyzes the achievement of the shipping policies and the priority for the promotion of such policies, in order to consider the features of the shipping industries in Korea and other advanced shipping countries and manage the rapidly changing shipping environment actively. Based on such analysis, this study also discusses the promotional strategy to strengthen the international competitiveness of the shipping industry. Regarding the promotion of the related policies, it is necessary to establish a base for growth, strengthen a capacity of leading the market, and create an opportunity in the market. By considering such three factors, it has become known that the establishment of the market order is important for the establishment of a base for growth. It is important to consider the advancement of the shipping tax system. Also, the information-orientation and the knowledge-industrialization of the shipping industry need to be considered. In order to strengthen a capacity of leading the market, the stable security of the labor force in the shipping industry is the most important factor. Also, it is important to consider the development and the upbringing of the global mega career and the shipping business. Regarding the creation of an opportunity in the market, it is important to expand the range of the shipping exchange between South Korea and North Korea, which will influence the administrative and the operative results related with the promotion of the related policies.

  • For the sake of the Restoration(to the original state) of "Sanbeon-bang(刪繁方)", in this study observed carefully the bibliographical results of "Oedaebiyo-bang", "Cheongeumyo-bang", "Cheongeumik-bang" and "Uisim-bang", which directly quoted "Sanbeon-bang". "Sanbeon-bang" is mostly remained in "Oedaebiyo-bang", and the other provisions of "Sanbeon-bang" mostly lie scattered in "Cheongeumyo-bang" and "Cheongeumik-bang", established 100years before "Oedaebiyo-bang" and "Uisim-bang", established 200years after "Oedaebiyo-bang". And there are few other documents which quoted the "Sanbeon-bang". "Cheongeumyo-bang", a synthetic medical work was compiled in 652, and which refered large quantity of medical documents before Dang-dynasty(唐代) by Son Sa-mak(孫思邈). And he linked the technical opinion of himself. The comments of medicine, as well as the prescriptions are refleting the outcome before Dang-dynasty systematically. For the most part of the medical arguments in "Sanbeon-bang" lie scattered in "Cheongeumyo-bang". "Cheongeumik-bang", also a synthetic medical work which is for the sake of supplement of "Cheongeumyo-bang" was complied in 682 by Son Sa-mak. As well as "CheongeumYo-bang" it doesn't make clear the sources of quotation from "Sanbeon-bang". So it used as the data for confirmation. "Oedaebiyo-bang" was compiled in 752 of Dang-Dynasty by Wang Do(王燾) the a governor-general of Eop-gun. Wang Do was descended from a noble family, and usually visited the palace and dealed with large number of books in Hongmunguan(弘文館), the national library. He programmed the book on the base of wide scopic collection of medical documents. And he took charge of gverment post at the same time as Wang Bing(王氷) who compiled "Chaju-Hwangje-Naegyeong-Somun(次注黃帝內經素問)" in 762. So we can guess they might have seen the same documents and holded the medical knowledge in common. The 40 volume "Oedaebiyo-bang" was a great medical complete book in those days. In particular, it became the model of medical complete books of after ages. The description of the book is mostly the qutation of medical documents of before ages. The character is recording of quotation documents and the order of volume. On the base of the recording, we can reconstruct the table of contents of Sanbeon-bang. By way of the contens, we can understand the purpose of "Sanbeon-bang". Besides, I can see a lot of qouotations of "Sanbeon-bang" in "Cheongeum-bang" and "Uisim-bang" are repeatedly quotated in "Oedaebiyo-bang". For that reason, I observed the bibliographical results of "Oedaebiyo-bang" in detail. "Uisim-bang" was compiled in 982 by the Japanese Niwayasyori(丹波綱賴). It followed the example of the structure of "Oedaebiyo-bang", refered to the contents of "Cheongeumyo-bang", collected chinese medical classic books spreaded in Japan. It contains medical documents of before Su-Dang(隋唐)-era, indicated the source of quotation. The importance of the book is summarization and preservation of large quantity of chinese medicine before 10th century. In this study, a lot of the quotation in "Uisim-bang" from "Sanbeon-bang" were not in "Oedaebiyo-bang".

  • The stability of firefighting pipes is crucial in the event of an earthquake. In Korea, specification-based designs are used in accordance with NFSC. However, engineering performance-based designs are used for buildings that have special requirements. For firefighting pipes, tree type pipe networks are usually utilized in buildings; however, they are characterized by several limitations. Hence, grid type and loop type networks are being utilized lately. Earthquake-resistant designs for firefighting pipes in Korea utilize NFPA 13 as the cookbook. Nevertheless, an engineering analysis is required to verify its reliability. The NFPA 13 standard used in Korea is a design method for engineers who lack earthquake engineering analysis knowledge of pipes and adapt ASCE and ASME guidelines. Earthquake resistant designs in Korea review braces only. Hence, various analyses under load conditions, such as the internal pressure of a pipe, force exerted by a continuous load, and an earthquake, are required to ensure reliability. An engineering earthquake-resistance analysis showed that tree type pipe networks are less stable than grid and loop type pipe networks. A comparison of earthquake-resistance analysis based on stress and strain revealed that strain analysis exhibited a conservative result value in the range of over-stress. Therefore, for the earthquake-resistance analysis of pipes, it is rational that engineers perform analysis to achieve the required standards through engineering analysis rather than uniform calculations, which should also be analyzed considering various analysis conditions.
