세계 및 한국경제의 성장과 함께 항공운송 시장의 급속한 확대에 따라 대한민국에서의 국제항공 운송 수요는 꾸준히 증가하게 됨에 따라 한국의 관문 역할을 담당하던 김포국제공항의 수용능력은 한계에 이르게 되었다. 따라서 정부는 김포국제공항을 대체할 인천국제공항을 건설하여 운영하는 한편 김포국제공항에는 한국 중국 일본의 수도를 포함한 몇몇 도시를 연결하는 근거리 중심의 국제선이 취항하게 되면서 공항운영에 대한 새로운 패러다임을 형성하게 되었다. 대한민국의 수도 서울의 항공교통을 위한 공항이 제한적이지만 복수공항 체계로 운영되면서 인천공항과 김포공항을 이용하는 항공여객은 공항 이용 시 선택의 기회가 주어지면서 공항운영자는 여객의 공항선택에 영향을 주는 요소에 관심이 점차 증대되고 있는 현실이다. 그러나 현재 국내에서는 항공여객의 항공사 선택에 관한 연구는 많이 이루지고 있으나 항공여객의 공항선택에 관한 연구는 상대적으로 미흡한 실정임을 부인할 수 없다. 따라서 본 연구는 항공여객의 공항선택에 미치는 속성이 무엇이고 속성에 따른 중요도와 만족도를 측정하여 공항운영자의 공항운영과 활성화 전략수립에 대한 정보를 제공하는데 목적이 있다. 본 연구에서는 김포공항 국제선 이용객을 표본으로 선정하여 설문조사를 실시하여 IPA 분석과 GAP분석 및 경로분석 기법을 사용하여 분석하였다.

The aim of this study is to analyze informatization competencies of the international ship supply companies at Busan port. This study comprehensively suggests certain issues attributed to the successful implementation of total information management system for ship supply. To achieve this objective, evaluation was undertaken based on the model of the National Competency Standards (NCS). This model consisted of three evaluation areas, including 20 items. Analysis of information competencies of ship supply companies was undertaken using the Importance-Performance Analysis (IPA) method. Survey data was collected from ship supply companies located in the ship supply center at Busan port. Results found that there were significant differences between importance and performance. In addition, overall informatization competency was very low. Thus, in order to ensure successful implementation of total information management system, re-education programs for ICT usage and dedicated support organization are necessary.

As recent safety accidents at construction sites can lead to serious accidents that threaten the lives of workers, the role of safety managers in charge of safety management has emerged. However, the current construction safety management system requires the improvement and simplification of the work contents due to the excessive workload and inefficient safety tasks of each person. In this respect, the main purpose of this study is to reduce the occurrence of construction safety accidents by deriving correlations using 2×2 Matrix analysis techniques through expert opinion, simplifying unnecessary tasks and identifying areas requiring improvement. Therefore, if this research reduces inefficient safety manager work and reduces job stress caused by excessive simple document work, thereby efficiently reorganizing safety manager's work to prevent blind spots of hazards and risks, it will ultimately have a great effect on preventing safety accidents at construction sites.

This study aims to analyze the level of members' awareness of records management in the Republic of Korea Army within the institutional context extensively. Accordingly, in-depth interviews were conducted after comparing and analyzing the institutional systems that restricted the members' record management activities. As a result, it was identified that the members were confused by the inconsistency among the systems that defined the work procedures, and that the value of responsibility and efficiency in the records management system does not match the organization's goals. Therefore, the legal justification of the system should be improved in harmony with the responsibilities and efficiency and to match them with the organization's objectives. Moreover, the improved system should be internalized by the members through instructions that are relevant to the content of the system. This study intends to increase awareness in the records management system and improve the system as well.

The goal of this study was to examine ways to improve the quality of databases of the Korean National Assembly Digital Library(KNADL). In order to achieve the goal, we first designed an assessment tool that could measure the quality of the 'contents,' the 'service,' and the 'system' of the KNADL's databases. Each of the three categories also had sub-categories-i.e., eight sub-categories for 'contents'(e.g., accuracy, recency, ${\cdots}$), seven sub-categories for 'service'(e.g., convenience for request, rapid response, ${\cdots}$), and seven sub-categories for 'system'(e.g., usability, response time, ${\cdots}$). We thenconducted a survey using the assessment tool we developed and gathered a total of 270 responses from users of KNADL's databases. We used Excel and PASW Statistics 18 for data analysis. Each sub-category was measured by its importance and by the level of satisfaction(implemented from the DigiQUAL project). Finally, we performed an importance-satisfaction analysis(ISA) to identify what action(i.e., maintain, concentrate, low priority, and exceed) needs to be made in each sub-category. We concluded the paper with some useful suggestions for improving the quality of KNADL's databases.

The purpose of this study was to analyze the types and characteristics of public complaints caused by the landscape architecture projects in the case of apartment complex. Furthermore, its purpose was also to propose as the basis data for the minimization of complaints in the course of future landscape architecture projects. To analyze and categorize the apartment complex civil complaints, we collected basic and case study data from LH Corporation, SH Corporation and GICO from 2009 to 2012. We also categorized 672 landscape complaints to 73 categories and conducted a survey from residents and landscape architecture. This Survey is to use IPA can collect character(public-private), handling of civil affair(easy-hard) and analyze typical characters and difference of civil complaint awareness between landscape architecture and residents. First, we were categorized 73 civil complaints by type in 5 categories such as park, green space and street trees, pedestrian road, facilities, and others. Second, the most common landscape complaints appear in green spaces, street trees, facilities, pedestrian roads and park orders. Third, results of the analysis conducted for each item which are publicity and measures the ease. 'Facilities', 'landscape and greenery', 'pedestrian road' and others were commonly appears from residents and professional awareness of the complaints. However, complaints of park appear different awareness between landscape architecture and residents. Fourth, 35 from 73 civil complaints(47.9%) are having high publicity and easy to measure, 25 civil complaints(34.2%) has analyzed to individual and difficult to measure so about the these complaints need to check from the design step so that it is necessary to minimize the problem of additional expense by civil complaints burden and decrease the confidence of residence problem were considered.

The steel cargoes as the core raw materials for the manufacturing industry have important roles for increasing the handling volume of the port. In particular, steel cargoes are fundamental to vitalize Port of Incheon because they have recognized as the primary key cargo items among the bulk cargoes. In this respect, the IPA(Incheon Port Authority) ambitiously developed the port complex facilities including dedicated terminals and its hinterland in northern part of Incheon. However, these complex area has suffered from low cargo handling records and has faced operational difficulties due to decreased net profits. In general, the import and export steel cargo volumes are sensitively fluctuated followed by internal and external economy index. There is a scant of research for forecasting the steel cargo volume in Incheon port which used in various economy index. To fill the research gap, the aim of this research is to predict the steel cargoes of Port of Incheon using the well established methodology i.e. System Dynamics. As a result, steel cargoes volume dealt with in Incheon port is forecasted from about 8 million tons to about 10 million tons during simulation duration (2011-2020). The Mean Absolute Percentage Error (MAPE) is measured as 0.0013 which verifies the model's accuracy.

An accurate feedback about customer satisfaction is a very important factor to efficiently manage achievements in the service industry. However, Korea is lack of quantitative and standardized system of customer satisfaction measurement. This paper suggests standardized survey system with more in-depth and various methods of questionnaire survey as well as analysis which is able to efficiently evaluate customer satisfaction. This system is that investigates customer satisfaction of process based services, which uses various methods including simply designed questionnaires, customer satisfaction survey via mobile, and an investigation on follow-up satisfaction rate. In addition, we adopted scoring system to digitize a degree of satisfaction rate, so the suggested system provides an opportunity to improve specific objects those need to be improved by clearly evaluating a degree of satisfaction rate and applying various analysis techniques, such as IPA (Importance Performance Analysis), process analysis, and expectation analysis etc. This study substantiates suggested system through applying it to travel agency which is a representative enterprise of tour service.

본 연구는 균질 및 2개층 비균질지반에서 사질토지반 상에 놓인 정방형 기초의 극한지지력과 침하에 대하여 고찰하였다. 본 연구는 얕은기초의 거동에 대한 정방형 기초의 크기, 지반 상대밀도, 기초 폭에 대한 상부층의 두께 비(H/B), 상부층 아래 경계면의 경사($\theta$) 그리고 지반강성비의 영향을 규명하기 위하여 모형실험을 수행하였다. 동일 상대밀도에서 지지력 계수($N_{{\gamma}}$)는 일정하지 않으며 기초 폭에 직접적으로 관련되며 지지력계수는 기초 폭이 증가함에 따라 감소하였다. 기초크기의 영향과 구속압력의 영향을 고려하는 Ueno 방법에 의한 극한지지력의 예측값은 고전적인 지지력 산정식보다 더 잘 일치하며 그 값은 실험값의 65% 이상으로 나타났다. $\theta$=$0^{\circ}$인 2개층 지반의 결과에 근거하여, 극한지지력에 대한 하부층 지반의 영향을 무시할 수 있는 한계 상부층 두께는 기초 폭의 2배로 결정되었다. 그러나, 73%의 상부층 상대밀도인 경우는 침하비($\delta$B) 0.05 이하에서만 이 결과가 유효하였다. 경계면이 경사진 2개층 지반의 결과에 근거하여, 상부층의 상대밀도가 느슨할수록 그리고 상부층의 두께가 클수록 극한지지력에 대한 경계면 경사의 영향은 크지 않는 것으로 나타났다. 경계면의 경사가 증가함에 따른 극한침하량의 변화는 경계면이 수평인 경우($\theta$=$0^{\circ}$)를 기준으로 0.82~1.2(상부층 $D_{r}$=73%인 경우) 그리고 0.9~1.07(상부층 $D_{r}$=50%인 경우) 정도로 나타났다.Markup Language 문서로부터 무선 마크업 언어 문서로 자동 변환된 텍스트를 인코딩하는 경우와 같이 특정한 응용 분야에서는 일반 문자열에 대한 확장 인코딩 기법을 적용할 필요가 있을 수 있다.mical etch-stop method for the etching of Si in TMAH:IPA;pyrazine solutions provides a powerful and versatile alternative process for fabricating high-yield Si micro-membranes. the RSC circle, but also to the logistics system in the SLC circle. Thus, the RSLC model can maximize combat synergy effects by integrating the RSC and the SLC. With a similar logic, this paper develops "A Revised System of Systems with Logistics (RSSL)" which combines "A New system of Systems" and logistics. These tow models proposed here help explain several issues such as logistics environment in future warfare, MOE(Measure of Effectiveness( on logistics performance, and COA(Course of Actions) for decreasing mass and increasing velocity. In particular, velocity in logistics is emphasized.
