  • The high prices and lack of information for satellite images prevent researchers from studying remote sensing and most non-professional people can't have the simple and easy solutions for the manipulation of satellite images. 'Satellite Imagery Information Management Center'(SIMC) project which is promoted by ETRI (Electronics and Telecommunications Research Institute) from 2002 to 2005 in Korea have the purpose to provide the satellite images freely to the public domain and the solutions for the above mentioned problems. Our project have the following five systems; Data Acquisition System, Data Preservation System, Integrated Solution System, Technology Development System, Operation Plan System. Data Acquisition System collects the satellite images such as LANDSAT, IKONOS, etc. Data Preservation System consists of database which registers the diverse satellite images. Integrated Solution System gives the user of public domain for the web service which search, order and transfer the satellite images. Technology Development System has the many processing technologies for the satellite images. Finally, the Operation Plan system has the role to plan the future of our SIMC project. In this paper, we will give the result of SIMC Project for each five systems during the fast four years from 2002 to 2005.

  • Arbitration is the system of resolving disputes not by the adjudication of a national court but by the award of an arbitrator or arbitrators. To settle disputes by arbitration, it should be concluded that the arbitration agreement which is implied that the parties agree to submit to the arbitral award about all or certain disputes which have arisen or which may arise between them in respect of defined legal relationships. It is a matter for debate that which types of dispute may be resolved by arbitration. This problem is concerning the arbitrability of the subject-matter of a dispute. National laws establish the domain of arbitration. Each state decides which matters may or may not be resolved by arbitration in accordance with its own political, social and economic policy. According to Korean Arbitration Act Art. 3 (1), any dispute in private laws would be the object of arbitral proceedings. Therefore, the parties may agree to arbitrate disputes relating to the rights that they freely dispose of. Besides, they may have the freedom to choose arbitration as the form of a dispute resolution. Because arbitration is a private proceeding with public consequences that some types of dispute are reserved for national courts, whose proceedings are generally in the public domain. It is this sense that they may not be the object of arbitration. After all, it could be the object of arbitral proceedings that disputes which are capable of a settlement by arbitration.

  • Purpose: This study has been designed to evaluate occupational health services on workers with hypertension Method: Study participants were 108 workers having a diagnosed hypertension. The instrument used for this study was the questionnaire developed by Cho(1998). Analysis of the data was done with SPSS Win 10.0 for descriptive statistics, Correlation coefficient. Results: 1. The mean score of process domain was $3.77\pm.43$ The score of process domains were usefulness of health management$(3.98\pm.49)$, education or counselling$(3.87\pm.53)$, follow up in medical examination$(3.79\pm.58)$, usefulness of providing materials$(3.53\pm.62)$, perception of medical examination $(3.37\pm.80)$ 2. The mean score of outcome domain was $3.47 \pm.44$ The score of outcome domains were obstructiveness of social life$(3.90\pm.78)$, habits of living $(3.41\pm.76)$, blood pressure change $(3.25\pm.81)$, perception of seriousness$(3.02\pm.88)$. 3. Blood pressure change was significant correlated with education or counselling(r=.31) and usefulness of providing materials(r=.28).

  • 최근 10년간 전세계적으로 아스팔트 포장을 재활용하는 기술이 급속도로 확산되고 있으며 노후 아스팔트 포장을 폼드 아스팔트 또는 유화 아스팔트를 사용하여 현장에서 바로 100% 재활용하는 현장 상온 재생 아스팔트 포장기술이 다양하게 적용되고 있다. 특히, 아이오와 주에서는 교통량이 적은 지방도로에서 기존 포장의 수명을 연장 시켜주는 현장 상온 재생 아스팔트 공법을 많이 적용하고 있다. 일반적으로 현장 상온 재생 아스팔트 포장층은 수분의 침투나 교통하중으로부터 보호하거나 포장설계를 만족시키기 위해 가열 아스팔트 포장으로 덧씌우기를 한다. 일반적으로 현장 상온 재생 아스팔트 포장층 위에 가열 아스팔트 포장으로 덧씌우기 할 시기는 대부분에 감독자들은 일정한 양생기간 또는 최대 함수비에 근거하여 결정하고 있다. 따라서, 본 연구에서는 감독자가 최적에 덧씌우기 아스팔트 포장 시기를 결정할 수 있도록 현장 상온 재생 아스팔트 포장층의 현장 함수비를 간단하게 측정하여 덧씌우기 시기를 결정할 수 있는 수분 감소계수를 개발하는 것이다. 먼저, 현장 상온 재생 아스팔트 포장층의 함수비를 TDR 함수량계를 사용하여 측정하였고 현장 상온 재생 아스팔트 포장이 시공되는 기간 동안에 강우량, 대기온도, 습도, 바람속도 등 기상정보를 수집하였다. 마지막으로 현장 상온 재생 아스팔트 포장의 초기 함수비, 대기온도, 습도, 바람속도를 변수로 하는 수분 감소계수를 개발하였다. 실제 현장 상온 재생 아스팔트 포장에서 측정한 값을 사용하여 개발한 수분 감소계수는 감독자가 연속적으로 현장 상온 재생 아스팔트 포장층의 함수비를 측정하지 않고 최적의 덧씌우기 포장 시점을 결정할 수 있다.

  • This paper presents a statistical technique for audio watermarking. We describe the application of the promising public key watermarking method to the patchwork algorithm. Its detection process does not need the original content nor the secret key used in the embedding process. Special attention is given to statistical method working in the frequency domain. We will present a solution of robust watermarking of audio data. In this scheme, an extension of patchwork audio watermarking is presented which enables public detection of the watermark. Experimental results show good robustness of the approach against MP3 compression and other common signal processing manipulations.

  • With the proliferation of mobile terminals, use of the Internet in mobile environments is becoming more common. To support mobility in these terminals, Mobile IPv4 is proposed and represents the standard in IPv4 environments. Authentication should be mandatory, because mobile terminals can utilize Internet services in any foreign domain. Mobile IPv4 provides symmetric key based authentication using the default HMAC-MD5. However, symmetric key based authentication creates a key distribution problem. To solve this problem, public key based authentication mechanisms have been proposed. In this paper, the performance of each of these mechanisms is evaluated. The results present that, among these mechanisms, partial certificate based authentication has superior performance, and certificate based authentication has the worst performance. Although current public key based authentication mechanisms have lower performance than symmetric key based authentication, this paper presents the possibility that public key based authentication mechanisms may be used for future mobile terminal authentication.

  • In this paper we propose a new algorithm which resolves the inconsistency problems occurring when DNS severs are employed as elements of PKI. The inconsistency may take place between primary name servers and secondary name servers and between cached certificate and original certificate. The former can be removed by adapting RFC 1996 NOTIFY opcode for DNS. In order to eliminate the latter type of inconsistency we develope a new algorithm which is implemented with two additional RR(Resource Record). The present algorithm is designed such that DNS contacts the destination DNS prior to returning public key to users. Therefore the inconsistency problem occurring when DNS is operated as PKI can be eliminated by using the proposed adaptation and algorithm.

  • Melvil Dewey는 도서관운동가, 사상가, 교육자 그리고 선각자 등 다양한 측면에서 평가받고 있다. 그러나 교육가로서 그의 생애는 도서관계에서는 관심 밖의 영역으로 남아있다. Dewey의 도서관 사상의 근원은 학교교육과 가정교육의 두 가지 측면으로 구분해서 볼 수 있다. 이러한 측면에서, Dewey는 도서관이 교육분야에서 수행해야 하는 기능과 역할 등의 방향을 설정하는데 큰 역할을 담당하였다. 하지만, Dewey의 이러한 교육관에 대해서는 국내 연구에서는 조명되지 않고 있다. 이러한 측면에서, 본 연구는 공공도서관에서의 생애교육을 Dewey의 교육사상을 중심으로 고찰해 보고자 한다.

  • Technology innovation companies are focusing on contributing to business performance by R&D project as a strategic tool. Successful R&D leads to corporate competitiveness enhancement, national industrial development, but there are high uncertainty and risks in R&D. Public and private R&D projects are carried out to achieve various purposes. It was verified how the risk management and benefit management of the R&D project affect the detailed R&D project performance between the Public and private domain. The impact of Project Leadership on R&D performance was also analyzed. Those who have participated in the Public and Private R&D projects at companies or research institutes were surveyed. First, it was found that project risk and benefit management have partially an effect on R&D project performance. Second, Public and private R&D Project Leadership showed partially a interaction effect between project management and project performance.

  • 공공데이터는 공공기관의 정책 수립 등의 공적 기능을 수행하기 위하여 많은 비용을 들여 수집되고 있으나 대부분은 사일로(silos)로 방치되고 있다. 우리나라도 공공데이터를 개방하려는 움직임이 활발해지고 있으나 일부 기관을 중심으로 OpenAPI 형식으로 데이터를 제공하는 등 제한적인 수준에 머물고 있다. 국가차원에서 LOD(Linking Open Data) 시범사업으로 공공DB 피디아를 구축하면서 최근 들어 공공데이터 활용을 위한 링크드 데이터 구축이 활발하게 논의되고 있다. 본 연구에서는 관련연구 및 공공부문을 중심으로 한 링크드 데이터 구축 사례를 바탕으로 공공데이터 활용을 위한 국가 연계체계 사업인 공공DB 피디아 구축과정에서 도출된 문제를 파악하고 기존의 국가DB 연계체계 구축과정을 참고하여 그 해결 방안을 제시하였다.
