  • In the present study, muscle tissues were obtained separately from individuals from Atlantic hairtail population (AHP), Gunsan hairtail population (GHP) and Chinese hairtail population (CHP), respectively. The seven decamer primers were used to generate the shared loci, specific, unique shared loci to each population and shared loci by the three hairtail populations. Here, averagely, a decamer primer generated 64.7 amplified products per primer in the AHP population, 55.7 in GHP population and 56.4 in CHP population. The number of unique shared loci to each population and number of shared loci by the three populations generated by genetic analysis using 7 decamer primers in AHP, GHP and CHP population. 119 unique shared loci to each population, with an average of 17 per primer, were observed in the AHP population, and 28 loci, with an average of 4 per primer, were observed in the CHP population. The hierarchical dendrogram point out three main branches: cluster 1 (ATLANTIC 01 ~ ATLANTIC 07), cluster 2 (GUNSAN 08 ~ GUNSAN 14) and cluster 3 (CHINESE 15 ~ CHINESE 21). The shortest genetic distance displaying significant molecular difference was between individuals' CHINESE no. 16 and CHINESE no. 18 (0.045). In the long run, individual no. 01 of the AHP population was most distantly related to CHINESE no. 19 (genetic distance = 0.430). Consequently, PCR analysis generated on the genetic data displayed that the geographic AHP population was widely separated from CHP population, while individuals of CHP population were fairly closely related to those of GHP population.

  • 본 논문은 광양항의 발전전략을 수립하기 위하여 SWOT/AHP분석을 실시하고자 한다. SWOT분석은 보통 전략수립단계에 있어서 내 외부 환경을 분석하기 위해서 사용된다. SWOT/AHP분석은 Kurttila et al(2000)이 SWOT분석의 유용성을 개선하기 위해 제안한 방법으로 SWOT분석의 결과는 단순히 SWOT그룹 내에 어떤 요인들이 있는가를 확인하는 것에 불과하다. 따라서 AHP분석과 결합함으로써 SWOT분석에서 도출된 요인들에 대한 상대적인 중요도를 평가하여 전략수립에 활용하는데 목적이 있다. 분석결과를 요약하면, SWOT그룹의 상대적 중요도는 기회(0.376), 강점(0.259), 위협(0.206), 약점(0.159) 순으로 나타났다. 다음으로 SWOT요인 별로 살펴보면, 강점요인의 상대적 중요도에서는 저렴한 화물처리비용(0.383), 우수한 항만입지(0.347), 광범위한 배후지(0.270) 순으로 나타났다. 약점요인의 상대적 중요도는 효율적인 통관시스템 미비(0.511), 복합운송 연계성 미비(0.315), 항만전문인력의 부족(0.173) 순으로 나타났다. 기회요인의 상대적 중요도는 각종 인프라 구축으로 수송체계 개선(0.461), 주변지역에 대한 연관산업단지 개발지속(0.326), 동북아지역의 물동량 증가추세(0.214) 순으로 나타났다. 위협요인의 상대적 중요도는 각종 인프라 구축으로 수송체계 개선(0.411), 주변항만과의 경쟁(0.400), 복합운송업체의 영세성(0.189) 순으로 나타났다. 평가대상이 되는 각 그룹별 세부요인들의 종합순위를 얻기 위하여 의사결정 항목들의 상대적 중요도를 종합화하였다. SWOT그룹별 세부속성요인들의 최종 중요도(가중치) 결과를 살펴보면, 기회요인 속하는 각종 인프라구축으로 인한 수송체계 개선(0.173), 주변지역에 대한 연관산업단지 개발지속(0.123)이 가장 높은 중요도를 보였고, 저렴한 화물처리비용, 우수한 항만입지, 항만운영의 융통성 결여, 주변항만과의 경쟁, 효율적 통관시스템 미비의 순으로 나타났다.

  • Korean IT industry has been given much weight in national R&D management. A negative side of this fact is that Korean economy is likely to become vulnerable to a condition of the export business in certain items of IT industry which has a serious influence on the national economy. A customized investment strategy through the analysis of technology competitiveness and R&D status in each technology of IT field is required in order to rectify the structural vulnerability and pursue a continuous growth. In this research, a strategic direction to set up an efficient investment strategy is presented. In this process, it draws a portfolio analysis with two axes of technology level and technology life cycle. It also derives a priority order of the national investment considering the degree of technological impact, marketability, and adequacy of public support from AHP (Analytic Hierarchy Process) method by a survey of IT experts. A portfolio analysis in the prior stage helps the respondents in AHP become more familiar with the alternatives' characteristics so that their decision making process more corresponds with national R&D strategies.

  • Recently, due to the economic recession and increase of ITO (IT Outsourcing), bidding in software industry has been recognized as more competitive and the importance of software bid evaluation for corporate selection is being increased. This study aims to analyze and prioritize influential factors in the software bid evaluation criteria which is adopted as the main evaluation model of national software businesses by Ministry of Science. The priority was developed by AHP (Analytic Hierarchy Process) through pair-wise comparison. For the analysis, this study developed analysis model for AHP and conducted survey of experts who have work experience for more than 10 years in the IT industry. As the result of analysis, weighted factors in the evaluation criteria were deduced and differences of priority factors between purchaser and bidder were investigated. The analysis showed differences of view point in the bidding process. With these results, this study suggests how to write a proposal strategically and effectively in perspective of the purchaser. It is expected that priority factors will be adopted in strategic proposals in both bidder and purchaser. For purchaser, the priority will be adopted to select reliable bidder. So, we expect that the priority factors will be used to get more values for both bidder and purchaser in their business atmosphere.

  • The objective of this research is to select the most effective technique from task related techniques(motion & time study, job redesign, physical environment improvement) for improving work efficiency in shipbuilding enterprise. This study consists of several principal steps. The first step is to design critical criteria in evaluating work efficiency in shipbuilding enterprises. The second step is to develop sub-criteria of the critical criteria. The third step is to develop a four level AHP(Analytic Hierarchy Process)structure using the critical criteria, sub-criteria and techniques from task related techniques. The fourth step is to develop the pairwise comparison matrix by each level of AHP structure, which was based on survey data collected at the H heavy industry. And the last step is to select the most effective technique from task related techniques using AHP analysis. The result of AHP analysis has shown clear difference in priority among task related techniques in terms of work efficiency of the shipbuilding enterprise: The reduction of normal time has more importance than the reduction of allowance time, motion & time study techniques are most important for the reduction of normal time, physical environment improvement is most important for the reduction of allowance time as well.

  • The purpose of this paper is to investigate the international competition power between Korean ports and Chinese ports according to the port efficiency scores of DEA(Data Envelopment Analysis) by newly introducing the priority vector of AHP(Analytic Hierarchy Process) to the DEA method. Empirical analysis shows the followings: First, there was not big changes of DEA rankings when we use the input-oriented CCR and BCC models after introducing the AHP priority vectors to the input variables. Yantian Port's competition power was declined, but that of Busan Port was up in the BCC model. Second, there was some changes of DEA rankings when we use the output-oriented CCR and BCC models after introducing the AHP priority vectors to the output variables. Rankings of Dalian, Qingdao, Shanghai Ports were up. But Shekou, Yantian Ports showed the declined ranking position in the CCR model. In the BBC model, rankings of Shanghai and Busan Ports were up. But those of Shekou and Yantian Ports were declined. The main policy implication based on the findings of this study is that The Ministry of Maritime Affairs & Fisheries in Korea and China should introduce AHP and DEA approaches when they measure the international competition power by using the porrt efficiency scores of DEA.

  • 본 연구는 SNA(Social Network Analysis) 분석을 사용하여 부산항 연구동향을 파악하는 것을 목표로 했다. 연구분석 결과, Degree 중심성 측면에서는 Busan port(0.223)가 가장 높은 중심성을 가지고 있는 키워드로 나타났으며, DEA(0.060), AHP(0.056), Container terminal 그리고 Port competitiveness(0.049)순으로 나타났다. Betweenness 중심성 분석결과에서도 Busan port(0.245)가 가장 높은 키워드로 나타났으며, DEA(0.048), Container terminal(0.044), AHP(0.039), Busan new port(0.032)순으로 나타났다. 동향분석에서는 부산항이 세계 항만과 경쟁에서 우위를 점하기 위한 효율성 분석(DEA), 전략선택 및 경쟁분석(AHP) 등이 상위 중심성을 가진다는 시사점을 도출하였다. 하지만 현재 중요한 이슈로 부각중인 4차 산업과 관련된 연구는 부족한 실정이다. 향후 연구에서는 매스컴, SNS 등의 사회데이터를 병행 활용한 연구가 필요하다.

  • 우리나라는 매년 집중호우로 인한 산사태로 인해 인적, 물질적 피해를 일으킨다. 반복적인 산사태의 피해를 방지 하기위해서는 산사태 예측 시스템이 필요하다. 본 연구에서는 안성시를 대상으로 GIS와 RS 자료를 활용하여 산사태 위험지를 분석하고자 Logistic 회귀분석 방법과 AHP 기법을 이용하였다. Logistic 회귀분석과 AHP 기법에는 6개의 인자(경사, 경사향, 고도, 토양배수, 토심, 토지이용)를 사용하여, 7등급으로 산사태 위험도를 분류하였다. Logistic 회귀분석 방법과 AHP 기법을 이용한 산사태 위험지도를 표본 자료와 비교하면 산사태가 발생한 표본에서 산사태 위험성이 높은(1-2등급)지역이 Logistic 회귀분석에서는 46.1% AHP 기법은 48.7%로 분류되어 AHP 기법이 분류도가 높다고 분석 되었다. 하지만 Logistic 회귀분석과 AHP 기법은 서로 분석 과정의 차이를 가지고 있기 때문에 Logistic 회귀분석과 AHP기법을 적용한 결과에 동일 가중치를 부여한 후 7개 등급으로 재분류(reclass)하여 산사태 위험지역을 추출 할 수 있는 방법론을 제시하였다. 그 결과 산사태가 발생한 표본에서 1-2등급지역이 58.9%로 분석되어 분류정확도를 높일 수 있었다.
