DSRC(Dedicated Short Range Communications), which is a radio mobile communication protocol in ITS, is suited for traffic related information services. But in WAC(Wide-Area wireless communications), we could consider a conventional communication infrastructure in the case of supporting other applications besides ITS. Especially considering the current the trends to introduce wireless internet service into the mobile communication network, wireless internet service in ITS system is valuable. Although ITS LLC(Logical Link Control) protocols recommended by Europe and Japan are effective for traffic related services, it is not suitable for services related with geographical information, image or internet. That is because the data traffic characteristics is changed according to service types. Therefore we suggest a logical link control algorithm effective for traffic information related services as well as internet web service, and analyze its performance. As a result of numerical analysis and simulation, proposed algorithm shows larger performance improvements. For traffic information related services, the performance of DSRC LLC recommended by Europe and Japan is the same as that of proposed LLC protocol. However, for wireless internet web service, the performance of proposed protocol is much better than that of LLC protocol used in Europe and Japan.

Under this economic circumstance, the logistics firms located in port take better advantages than those in other areas. This study observed those firms with consciousness to which matters were affected a growth of the logistics IT firms. This study considered in terms of three factors which are an economic factor, a political factor and an internal-ability factor for the matters of logistics IT firms' success through the factor analysis. According to the factor analysis, subjective factor showed positive: (1) expanding market through the ideas and abilities, (2) internal relations and government support (3) capability of market identification and focusing on regional industrialization. As a result of the internal ability analysis, there were three positive matters such as (1) a factor of organization or human resource management, (2) relationship with consumer and resource and management ability for strategy, and (3) developing unique product, networking, suitable goods of regional industrialization. The external factor, through the factor analysis was trued out (1) a emerged political factor such as a support up venture, cluster composition, investing R&D and specialist training, (2) economic factor such as tax reduction, financial support, marketing collaboration renting office in a low price by regional government.

In order to facilitate the R&D of SMEs and foster innovative SMEs, the Small and Medium Business Administration is funding the SMEs in the focused supporting industries which are selected by a primary consideration of the political conformity. The correlations among the distribution of engaged SMEs, the distribution of SMEs which applied the fund, and the distribution of SMEs funded in the industries are analysed, in order to realize the effectiveness of the top-down method for selecting the focused supporting industries. As a result, there was a large deviation of both the number of the engaged SMEs and the number of the applied SMEs in the each industry, which means that the selected industries did not accurately reflect the needs for the technology development of SMEs. In addition, the distribution of the applied SMEs was strongly depended on the distribution of the engaged SMEs, which shows the trend that SMEs are trying to make R&D plans in their current industry rather than following the political drive. Moreover, because the distribution of the funded SMEs is strongly correlated with that of the applied SMEs, one could know that the selected industries were neither fostered strategically nor evenly but the fund was distributed simply according to the distribution of the applied SMEs. In this study, in order to complement the limitations of the top-down method, the bottom-up method which primarily consider the needs for the technology development of SMEs was suggested. It is desirable to consider in the order of the needs and the capabilities of SMEs, the technological perspective and marketability of the industry, and the political importance in the bottom-up method, and it is expected that the method could be flexibly used in the planning of the various programs.

As the social development progress, social welfare policy for people with disabilities also advance to meet rights of people with disabilities. The personal assistance service(PAS) is the primary service system for persons with disabilities based on guaranteeing the self-determination. The purpose of this study was to compare the personal assistance service system between Japan and Korea to propose improvement plan for Korean system. The comparison of two countries was based on current situation analysis of PAS. The analysis on eligibility criteria, information referral, amount and type of services and service provider, appealing process and service fee deductible etc. The result showed that PAS in Korea is served according to administration convenience than personal need based. Korean PAS policies are limited to particular service amount and type of needed services to satisfy personal PAS need. Whereas, Japan PAS system is served on the philosophy of independent living paradigm and therefore, PAS is provided on personal service needs. The service emphasis is on self-determination and rights on service selection for persons with disabilities. The recommendation for improvement of PAS in Korea are as followed. First, PAS should served under independent living paradigm. Paradigm based service is important because it effects the main theme of PAS; the self determination and rights of service selection. Second, reconstruction of PAS system is needed. As it showed on analysis, eligibility criteria, information referral, amount and type of services and service provider, appealing process and service fee deductible need to be supplemented. Last, to better serve PAS, case management method should be apply. Case management would contribute to settlement of PAS system in Korea. Thru case management, participation opportunities of people with disabilities must be provided during the selection of service quantity and type of PAS.

최근 몇 년 사이 정부 내의 정보화 사업규모는 기하급수적으로 증가하고 있다. 국민의 정부시절 약 2,400억 규모의 정보화 예산이 참여정부에서는 약 9500억으로 증가한 사실이 이를 반증하는 증거이다. 그러나, 이러한 정보화 사업에 대한 투자규모에 비하여, 막대한 예산을 들여 진행되는 사업에 대한 지속적인 성과관리는 체계적으로 진행되지 않은 현실이다. 오히려 성과관리라는 것이 사업의 추진을 방해하는 부정적인 요소로 인식되기도 한다. 하지만, 정보화 사업에 대한 성과관리의 부재는 장기적으로 조직의 전략목표와 정보서비스와의 GAP을 심화시켰고, 결과적으로 막대학 IT 투자 전체에 대한 회의감만을 대두시키는 결과를 가져 왔다. 2006년 IT최대의 화두인 IT거버넌스 개념 역시 IT와 비즈니스의 GAP을 줄여 IT 서비스가 조직의 목표와 전략을 올바르게 지원하도록 IT운영을 하자는 것이 핵심사상이다. 이러한 IT거버넌스 실현의 중심에 IT 투자성과관리체계가 있다. 해양수산부는 IT투자성과관리체계구축을 통하여 정보화사업 전체 프로세스를 지원하며, 각 단계별 이력관리를 통해 매년 사업 담당자가 바뀌는 상황에서도 안정적인 사업의 추진이 가능하도록 하였으며, 각 사업에 대한 평가지표개발 및 평가체계 구축을 통해 사업계획, 시행, 종료 단계에서 과학적인 정보화 사업의 투자성과평가를 지원하는 체계를 마련하였다. 이러한 IT투자성과관리체계는 기 구축된 ITA, ITAMS, IT자산관리체계와 연동하여 해양수산부 IT거버넌스 실현에 이바지 할 것으로 기대된다.

IT 또는 소프트웨어 교육에 있어서 완성도 있는 프로젝트를 생산하도록 하는 프로젝트 수행중심의 교육이 적합한 것은 해당 교육계에서 공감대를 형성하고 있으며 바람직한 대학의 커리큘럼이 구체적으로 제시되기도 하였다. 이러한 인식의 선상에서 정부의 지원정책이 방향을 잡은 것은 비교적 최근의 일이라고 생각된다. 이에 따라 많은 대학에서 프로젝트 수행중심의 교육을 시도하고 있으며 이는 매우 고무적인 것으로 받아들여질 수 있다.

This study analyzes the effectiveness of government supported R&D program for SMEs by measuring TFP improvements. We estimate TFP for Korean companies from 2011 to 2018 using Levinsohn and Petrin (2003) method which reduces endogenous problem. Then government R&D beneficiary companies were extracted from the NTIS and linked to TFP estimates. The empirical results are as follows. First, as a result of estimating production function, the contribution of TFP to value-added is more important than in the past. Second, the TFP gap between large firms and SMEs continues to wide and there is no sign of easing.(from 3.72 times in 2011 to 5.23 times in 2018). Third, SMEs beneficiaries show higher TFP level than non-beneficiaries. However their TFP was on the decline until government support. After government supported R&D program, it reverses upward. Fourth, although one-year TFP improvement of beneficiaries is bigger than non-beneficiaries, it is smaller than the control group through PSME. Because SMEs participating in government R&D programs had showed downward trend of TFP until R&D program, it is necessary to examine whether there is a fundamental discordance between the demand of SMEs for R&D program and governments policy goal. More sophisticated program design will be required to escape the recognition that government R&D programs for SMEs are just charity.
