KIPRIS patent database was analyzed for identifying the technological status of Daedeok Innopolis Biocluster. It was found that the pattern of activities among various technological areas in Daedeok Biocluster is similar to that of an advanced country rather than those of other cities in Korea. The technological growth in Daedeok Innopolis Biocluster is in the progressive stage, which may be due to the innovative activities rather than the rise in the number of new firms or institutes. The concentration of technology in Daedeok Innopolis Biocluster is a favorable condition for the innovation activities. The trend for the technological concentration was remarkably consistent with the growth curve that a population increases according to the logistic equation. The logistic growth may be represented by the result of competition due to the limited resource allocation and then innovation cluster is corresponding to the ecosystem composed by biological individuals. There is strong competition in Daedeok Innopolis Biocluster in around 2009, so the government might make a policy to encourage the technological diversity for healthy knowledge ecosystem.

As Asia becomes increasingly integrated economically, opportunity particularly in managing financial flows, as bases to coordinate regional production networks, and as staging points for the penetration of new markets. The paper argues for a path-dependent logic to understanding the efforts of the Singapore State in hosting hub functions. As a city-state without a national economic hinterland, Singapore's response to increasing business costs and regional competition has been to create a set of policies designed to encourage multinational companies to keep administrative control functions in Singapore while moving the more labour and land intensive production functions to nearby Malaysia and Indonesia. An understanding of the competition among cities in the Asia Pacific for hub functions must also take into account corporate strategy within particular industry dynamics. The second half of the paper provides a number of case studies to show this interplay between corporate strategy, industry dynamic and government policy.

After the sailing of WTO setup, The opportunity of a trade range extension is provided. OECD joining the change of the domestic construction industry. In 1994, The complete opening of a construction license was allowed As a result, The number of construction companies was increased rapidly. accordingly, We are faced with the new over competition and the problem of the financial difficulty. This paper proposes the plan for the practical technology of the small and middle sized construction companies to be improved and the plan for the working environment of small and middle sized construction companies to be improved. As a method for it, This paper proposes the Losicstics System of the construction.

Up to the present, ISO 9000 series have contributed which construction of quality management system and improvement of quality competition. Therefore many enterprises have taken an increasing interest in ISO 9000 series and the number certification of it is on the increase every year. In these processes, the side effect has come out. It is of no use to competitive power of enterprise. Because they made an effort for certification without preparation for a short period or there was no continuous system control. In this paper, We review the weakness of existing ISO 9000 series, which have soon ahead of revision. In addition, We propose the considering items or contents in revision for enterprise competition power.

As being various user telephone number after entry of new telecommunication enterprise, management of systematic Directory Assistance Service is required. Also through providing competition of Directory Assistances Service, enhancement of Service quality and development of new Service are induced. In this study, there is researched the overall view of present Directory Assistance Service in priority Korean Telecom and the oversea's Directory Assistance Service for U.S.A, England, Australia, Japan. As result of study, we want to suggest the appointment of unified Directory Database Management Company and outsourcing of Directory Assistance Service to that company but in reality, there may be other idea also with regard to various circumstances.

ACORN is an authenticated encryption algorithm proposed as a candidate in the currently ongoing CAESAR competition. ACORN has a good performance on security and efficiency which has been a third-round candidate. This paper mainly concentrates on the security of ACORN under the forgery attack and the non-repudiation of ACORN. Firstly, we analyze the differential properties of the feedback function in ACRON are analyzed. By taking advantage of these properties, the forgery attacks on round-reduced ACORN are proposed with a success probability higher than $2^{-128}$ when the number of finalization rounds is less than 87. Moreover, the non-repudiation of ACRON in the nonce-reuse setting is analyzed. The known collision can be used to deny the authenticated message with probability $2^{-120}$. This paper demonstrates that ACORN cannot generate the non-repudiation completely. We believe it is an undesirable property indeed.

The purpose of this study is to investigate the level of competition between Public Health Centers (PHCs) and private clinics (PCs) by examining the number of patients that used PHCs vs. PCs, estimating the total amount of revenue generated from outpatient services at both PHCs and PCs, thereby analyzing the financial impacts on PCs derived from the PHCs. We utilized 2011 National Inpatient Sample data (NIS). Using the 20 table containing general information on each individual claims, we integrate it with the 40 table which contains all the diagnostic codes for each claim. Then, we disaggregate the bundled claims into the original individual claims. Overall, 3.1% of outpatient visits are made at PHCs while the rest was made at the PCs (96.9%). Among the total claim costs of 6.34 billion USD (as of 2011), PHCs occupy 2.0% (124 million USD), and 98.0% are contributed to PCs (6.21 billion USD). The estimated economic losses of PCs due to PHCs are summarized as follow; the maximum potential loss is estimated at 198 million USD in total and 7,099 USD per clinic when we include all patient types; the minimum loss is estimated at 71 million USD in total and 2,540 USD per clinic where Medical Aid recipients and the elderly (aged 65 and over) are excluded. Our results confirm the potential economic effect on PCs due to PHCs providing outpatient services. PCs and PHCs are the most important players providing primary care in Korea. Unnecessary competition between PCs and PHCs is not desirable. Health authorities should carefully examine the healthcare services currently provided by PHCs and their impacts on PCs.

본 연구는 공공도서관에서 운영 되었던 독서마라톤 대회의 현황을 비교 분석하여 성과 향상을 위한 과제를 탐색하고, 더불어 향후 이 대회를 적용할 곳들을 위한 가이드라인을 제공하는데 목적이 있었다. 따라서 연구 목적 달성을 위해 코로나-19 팬데믹 이전부터 2021년까지 독서마라톤 대회를 운영한 공공도서관 다섯 곳의 현황을 수집하여 그 내용들을 비교 분석하였다. 그 결과 다섯 곳의 공공도서관이 독서마라톤 대회를 운영한 평균 기간은 10년이었고, 한 해 동안 대회 기간은 평균 5.87개월이었다. 또한 완주 비율이 가장 높은 대상은 아동이었으며, 완주에 대한 보상으로는 증서를 발급하고 대출권수를 상향시켜 주는 경우가 가장 많았다. 그러나 대회 담당자들은 신청자 확보 및 증대, 도달한 거리 산정 등에 대한 어려움을 호소하고 있어, 분석한 내용을 바탕으로 독서마라톤 대회 성과 향상을 위한 개선 과제를 도출하고 그에 대한 해결 방안도 제언하였다.
