ITS (Intelligent Transportation System) has been more popular but ITS project managements remain complex because of diverse stakeholders and multidisciplinary processes of ITS. The multidisciplinary process enforces specialized competencies on ITS project managers comparing to other system integration project managers. In this paper, we derived core competencies of ITS projects from previous researches, built the hierarchy of the competencies, and employed AHP (Analytic Hierarchy Process) surveying ITS project managers and auditors with the hierarchy. Finally, we analyzed the difference of evaluation model on ITS project manager between project managers and auditors using Mann-Whitney U test. Additionally we suggest a method of building MECE (Mutually Exclusive and Collectively Exhaustive) structure for AHP using the HoQ (House of Quality). We expect our model to give some inspirations for raising capable ITS project managers and selecting a proper project manager for an ITS project.

Recently, automobile traffic systems are evolving toward Intelligent Traffic Systems(ITS) with smart sensor technology and collaboration between traffic systems and external ones. On the contrary, Korean ITS services have little improvement comparing with other communication services. The main causes of this phenomenon are due to already allocation of ITS recommended frequency band to broadcasting services, and also dedication of DSRC frequency band over ISM band resulting in interferences. This paper provides the analysis of current Korean ITS technology status, and two suggestions to activate the ITS industry. First, need to fix the ITS standard combining WAVE and DSRC specifications soon. Second, ITS frequency allocation to complete its standard implementation in near time frame.

정부는 현재 직면한 교통문제 해결의 필요성을 인식한 후 1993년부터 대통령 직속 SOC 투자기획단에서 ITS 도입문제를 검토하기 시작하여 1997년 「국가 ITS 기본계획」을 수립히였다. 이를 토대로 정부 및 산·학·연등이 능동적으로 참여하여 ITS 사업이 추진되어 왔다. 그러나 1998년 외환위기에 직면하면서 ITS 사업에 대한 투자 감소등의 환경변화와 동시에 ITS 전문가들은 공급자 중심에서 최종 사용자 중심의 기본계획의 필요성을 제기하면서 ITS 기본계획 개정 필요성이 제기되어 더 현실적이고 융통성이 있는 기본계획을 수립하게 되었다. 이러한 배경을 기본으로 본 논문은 개정된 국가 ITS 기본계획의 내용 즉, 제공서비스, 단계별 구축계획, 단계별 예산 등을 살펴본다.

Dendropanax morbifera is an endemic tree species of Korea, it is restricted to the southern parts of Korea. The internal transcribed spacer (ITS) region of nuclear ribosomal DNA (nrDNA) for Dendropanax morbifera grown at Bogil-do, Korea was determined. We investigated the sequence-based phylogenetic relationships of plants related and clarified its taxonomical position. The determined sequences consisted of 689 residues. ITS1 was 222 bp long while ITS2 was 233 bp long. The 5.8S rDNA was 160 bp long. The ITS region sequences of the Dendropanax species included in this study were obtained from GenBank. Oreopanax polycephalus was used as the outgroup. A pairwise alignment was calculated using the Clustal X program. A phylogenetic tree was constructed by the neighbor-joining method using the Tree view program. Sequence similarities among species including D. morbifera Bogil-do isolate showed the range 92.6 to 99.7% in sequence-based phylogenetic analysis using total 615 base pairs of ITS1, 5.8S rDNA and ITS2. D. morbifera Bogil-do isolate exhibited the highest degree of relatedness to D. chevalieri, sharing 99.7% ITS region similarity. D. morbifera Bogil-do isolate also showed to D. trifidus, sharing 99.4% ITS region similarity.

Intelligent Transport Systems (ITS) was first introduced in Korea early 1990's, and Korean government has put a lot of efforts for flourishing it in the entire nation. Regardless of these efforts, private participation is not active enough to accelerate ITS implementation in Korea. Expert group made every endeavor to analyze the current situation, and found out some phenomena. It may be summarized as two folds. Firstly, private sector has a lack of confidence on the future ITS market. Budget in the strategic plan is the only publication and guide that private sector can refer to, and it merely indicates deployment costs. Secondly, direction and procedure of R&D are not well defined. It implies that private sector takes too much risk when they invest for R&D. This research, therefore, focuses on the first issues. Concretely, the goal of the project was to establish and analyze the model for estimation the future ITS market side. Author reviewed both quantitative and qualitative models, and concluded that diffusion model in qualitative model was suitable for ITS market estimation. According to model calibration. it is estimated that 14 trillion Won was the market size in 2020 under normal condition. Impact of this result may seduce Information Technology(IT) related private companies into ITS market. Although this research couldn't cover various topics, it nay dedicate in boosting ITS in Korea. Also, it will be a good starting point for further study for the advancement of ITS.

This study was carried out to confirm the phylogenetic relationships in Korean Rhus species. Sequences from internal transcribed spacers (ITS) of nuclear ribosomal DNA and rbcL gene of chloroplast DNA were determined. Cotinus coggygria was selected as outgroup because it is closest allied with Rhus in Anacardiaceae. Also, ingroup was limited as six Korean Rhus species. ITS 1 sequences in six species of Rhus and one species of Cotinus ranged from 246 to 253 bp and ITS 2 sequences from 234 to 244 bp. Concerning the G+C content of the studied taxa, ITS 1 sequences ranged from 58.0 to 68.13% and ITS 2 from 59.75 to 68.46%. On the other hand, rbcL sequences were same size in the all species examined by 1,428 bp. G+C contents of rbcL sequences were ranged from 43.56 to 43.77% which means there are nearly no different from interspecies each other. Phylogenetic tree strongly supports the colse relationships between R. succedanea and R. sylvestris. Rhus javanica and Cotinus coggygria were also closely allied with each other in ITS and rbcL trees. Therefore, R. javanica was regarded as most primitive species among the Korean Rhus species. ITS 1 region of nuclear ribosomal DNA was suggested as very useful taxonomical marker for genus Rhus.
