The purpose of this article was to propose improvement of countermeasure for missing person cases. While current related other studies examined practice of the countermeasure from inner viewpoint of police authorities itself, this study focused on and analyzed concern or criticism expressed through mass media, outside of the authorities. For this purpose, we analyzed newspaper articles dealing with missing person issued during past 5 years with qualitative data analysis software. The analysis revealed that civil community demands immediacy of coping with missing, phased expertise, systemicity of the countermeasure, improvement of relating policy, and active liaison with community. According to the needs, we proposed advancing risk assessment procedure, enlarging dedicated team for missing case, improving profiling-input system, adding duty for family of missing person, and enhancing of function of control tower.

In an extended enterprise, there is a shift to shared services, cosourcing and outsourcing, and extending out to partners, suppliers, and customers to accomplish business objectives more effectively. Along with this critical need, executives should be aware of the need to focus on optimizing the value of their information technology and reducing the related risks. So IT governance is critical, and many companies including spin-off venture are providing IT governance solution, but very little is known about brand management and marketing strategy of IT governance solution provider. The purpose of this study is to investigate brand positioning of IT governance solution company focusing on spin-off venture. The results of this study are summarized as follows. First, brand management is needed in the spin-off venture. second, IT governance solution companies including spin-off venture must provide something more than functional value. That is, they actively seek to emotional or symbolic value for their customers.

새 천년을 맞이하여 국내 이동전화 시장은 규모와 기술적 측면에서 놀랄만한 변화 를 겪게 될 것이다. 음성중심의 2세대 이동전화 서비스는 보급율이 50%를 넘어서며 포화수 준에 근접하고 있으며, 앞으로 무선데이타 통화량이 크게 증가하여 3~4년 후에는 총 통화량 의 50% 이상을 점유할 것으로 예측된다. 통신사업자들은 통신망의 광대역화와 글로벌화, IP Network 화를 더욱 강력하게 추진하고 있으며, 올 연말로 예정된 IMT-2000 사업자 선정은 이러한 추세를 더욱 가속화시킬 것으로 전망된다. 특히, 인터넷과 이동전화의 융화는 인간의 삶과 문화를 한순간에 변모시킬 혁명적 위력을 내포하고 있다. 정보화 시대를 향한 정보통 신업계의 대변혁이 그 절정을 향해 가속도를 붙이기 시작한 것이다. 신세기통신은 이러한 변화와 혼돈의 거친 물결 속에서 21세기 '정보통신 업계의 강자'로 도약하기 위한 힘찬 항해 를 진행하고 있다. 2000년 상반기까지 IS-2000시스템을 구축하여 최대 144kbps 수준의 고속 데이타 서비스를 제공하는 한편 i-TOUCH 017 컨텐츠 (Contents)를 한층 다양화, 첨단화 하는 등 본격적인 이동인터넷 사업을 전개해 나갈 것이다. 또 CDMA 국제 자동로밍 서비스 를 일본, 미국, 유럽 등 전세계로 확대하여 017 서비스의 글로벌화를 이룩할 계획이다. 이러 한 통신망 진화와 이동 인터넷 사업의 상당 부분을 SK텔레콤과 함께 추진하게 될 것이며 이러한 양사간의 전략적 제휴에 따른 시너지 효과는 오는 연말 IMT-2000 사업권의 성공적 확보로 이어질 것으로 기대된다. 21세기 정보통신산업은 광대역 통신망으로 대변되는 하드 웨어와 인터넷 컨텐츠로 대변되는 소프트웨어가 서로 융화되는 방향으로 발전할 것이다. 이에 따라 고객의 서비스 만족도나 사업자 선택 기준은 기존 통화물질 중심에서, 사업자가 제공하는 컨텐츠의 다양성이나 편리성으로 변화하는 것이 국적을 바꾸는 것보다 어려운 시 대가 멀지 않은 미래에 도래할 것이다. 신세기 통신 과 SK 텔레콤에는 현재 1,300만명이 넘 는 고객이 있으며. 이들 고객은 어 이상 음성통화 중심의 이동전화 고객이 아니라 신세기 통신과 SK텔레콤이 함께 구축해 나갈 거대란 무선 네트워크 사회에서 정보화 시대를 살아 갈 회원들이다. '컨텐츠의 시대'가 개막되는 것이며, 신세기통신과 SK텔레콤은 선의의 경쟁 과 협력을 통해 이동인터넷 서비스의 컨텐츠를 개발해 나가게 될 것이다.

Recently the World Bank released its World Development Report 2009 (hereafter WDR 2009) with the title 'Reshaping Economic Geography.' In the report, the Korean experience in regional development policy was highly praised. Also, the current government has been trying to reshape the regional development policy in view of 5+2 Economic Regions. The main theme of this paper is how to establish the highly valueadding economic system and how to deal with scale economies for regional development. In this paper these tasks in Korea's regional policy were discussed with reference to the WDR 2009. Enhancing the density of the central city of each Economic Region, reducing the economic distance between cities and rural areas, and getting rid of the barriers to cooperation between provinces are the keys for the efficiency and the effectiveness of the regional policy. In addition, strengthening the national solidarity through collaborative development of 5+2 Economic Regions still remains as one of the major tasks of the Korean government.

National statistical system in Korea has developed along with national economic agenda such as a government oriented high economic growth and has formed to a typical diversified statistical system. While the national statistics have been produced whenever they are needed, they are facing the critics that production of basic statistics were lack of balance. Grasping the statistical demand properly, enhancing the statistical concurrence with international organization, preventing the production of overlapped and similar statistics, and improving the professionalism of manpower in statistical industry are the structural problems that Korean statistical system has to get over. It is important to strengthen the coordination mechanism and the governance structure of the national statistical system to level up the integrity and credibility of statistical program. The length of Chief Statistician's tenure need to be assured.

Supporting QoS (Quality of Service) for the multimedia applications becomes an important issue as the demand of multimedia applications increases. Thus, it is necessary for the application layer to have an efficient congestion control algorithm, which can support the multimedia applications' QoS requirements. In this paper, we propose a new application layer congestion control algorithm, called RRC-OTT (Receiver-based Rate Control with One-way Trip Time). RRC-OTT algorithm differs from the previously proposed algorithms in that the receiver takes the responsibility of the network congestion control. Thus, RRC-OTT algorithm can not only precisely estimate the network congestion using OTT (one-way Trip Time), but reduce the work load from the sender (e.g., the web server). Our simulation study shows that RRC-OTT algorithm can maintain the comparable link utilization to the previously proposed algorithms and keep the packet jitter low, which thus can help enhance the quality of multimedia applications.

In this paper, we consider a novel spectrum sensing system in which firstly, the fusion center (FC) senses and makes the own decision then if its sensing result is not useful for achieving the final decision, the local observations from the cognitive users (CUs) will be required. Moreover, in case that FC needs the results from CUs, we will choose only CU having the highest collected energy to send its local decision to FC. Based on this selecting method, the number of sensing bits can be reduced; hence, we can save the power and the bandwidth for reporting stage in the cognitive radio network (CRN). The mathematical analysis of the key metrics of the sensing schemes (probability of detection, false alarm, e.g.) will be investigated and confirmed by the Monte-Carlo simulation results to show the performance enhancement of the proposed schemes.

International financial crises of the mid-l990s are widely perceived as the trigger that prompted recognition of the need for a new data quality management by the OECD, IMF, Eurostat and individual statistical agency. The official statistics improvements schedule in Korea was launched in 1996 as part of a broader internationally-agreed-upon initiative to strengthen transparency and promote good governance practices. These new initiatives are based on the Total Quality Management(TQM) movement and other management frameworks broadening the concept of quality beyond the traditional statistician's concepts of data quality. This paper aims to evaluate the statistics quality of Land Price Index. Evauation Method is the National Statistical Office's Data Quality Management System which focus on accuracy, timeliness, relevance, accessibility, comparability, serviceability, efficiency.
