This study is aimed to extract the key role of port operation organizations for the development of region ports and identify the operating efficiency priorities of three ports such as Busan, Incheon and UIsan port operated by PA(port authority). The Factor Analysis(FA) and Fuzzy Method were used as the analysis methodes. As an important role of port authority and regional maritime affairs & port office, thirteen sub-evaluation factors and four top-level evaluation factors were selected using the FA. Among the top-level evaluation factors i.e. 'port security, information management', service for regional society and customers', 'port marketing' and 'customer attraction', the most important factor was identified as 'port marketing'. The total port efficiency was evaluated using these factors and Fuzzy Method. As a result, Busan ranked 1st, followed by Incheon and Ulsan.

The shared-office business started with the lending of office spaces such as meeting rooms. From this came the coworking space, which maximizes the collaboration among the residents and promotes synergy among them. The purpose of this study was to analyze the characteristics of the coworking space. In addition, this study derived the factors that are considered important among the hardware- and software-level operating components, and presented the priorities according to the importance through a questionnaire survey and analysis for the employees currently utilizing a coworking space. For the results of the analysis, the top elements in the survey were found to be "spatial composition," "membership management," coworking management," and "architectural elements." In addition, when the general items were analyzed according to their characteristics, it was found that there was a difference in priority level among the elements of each characteristic. These results are expected to be useful when designing coworking spaces in the future. The results of this study can be used as the basic data for solving the problems of small companies and the environment, among others. Furthermore, the results of this study can be utilized as the basic data for the development of a collective shared community through linking at the local or national level, rather than being limited to a single space.

그래프를 사용하는 데이터 표현법은 직$\cdot$간접적으로 실세계를 표현하는 다양한 데이터 모델 중에서 가장 일반화된 방법으로 알려져 있다. 기본적으로 그래프는 정점과 간선으로 구성되며, 정점과 간선은 그 중요도나 운영 목적에 따라 다양한 가중치가 부여될 수 있다. 특히, 이러한 그래프를 순회하는 트랜잭션들로부터 중요한 순회패턴을 탐사하는 것은 흥미로운 일이다. 본 논문에서는, 정점과 간선에 가중치가 있고 방향성을 가진 기반 그래프가 주어졌을 때, 그 그래프를 순회하는 트랜잭션들로부터 가중치를 고려하여 빈발 순회패턴을 탐사하는 방법을 제안한다. 또한, 이렇게 탐사한 결과에 가중치를 고려한 중요도를 평가하여 빈발 순회패턴들 간의 우선순위를 결정할 수 있도록 한다. 이 과정에서 발생할 수 있는 트랜잭션 노이즈는 기반 그래프의 간선 가중치의 평균과 표준편차를 이용하여 제거함으로써 보다 신뢰성 있는 빈발 순회패턴을 탐사할 수 있다. 제안한 논문은 웹 로그 마이닝 등 그래프를 이용하는 다양한 응용 분야에 적용할 수 있을 것이다.

치열한 경쟁사회에서 고객 만족도를 높이기 위해서 고객관계관리(CRM: Customer Relationship Management)개념이 대두되고 있으며, CRM의 효과적인 수행을 위해서는 기업이 행하고 있는 고객서비스에 대한 정확한 평가가 중요하다. 여러 지표를 모두 고려하는 전략을 세우는 것은 현실적으로 불가능 하기 때문에 지표간의 개선 우선순위와 개선 폭, 개선방향을 결정할 수 있는 정보가 필요하다. 본 논문에서는 고객서비스를 평가하는 경우, 고객이 각 서비스 품질지표에 대해 느끼고 있는 중요도와 현황 및 속성에 대해 종합적인 분석을 위해 수정된 Kano 모델에 근거한 중요도-성과분석 방법론을 제시하고자 한다. 응답의 모호성으로 인한 문제점을 최소화하고자 퍼지기법을 이용하였다. 방법론의 검증을 위해서 K사의 이동통신 서비스에 대해 20대의 남녀 대학생 27명을 대상으로 사례연구를 실시하였다.

영국의 "기업과실치사법", 캐나다 및 호주의 기업처벌을 강화하기 위해서 형법을 개정하였음에도 불구하고 산업재해 감소 효과는 미미하다. 건설 현장의 불안전한 상태 방치 및 가설구조물에서 강도 높은 안전사고가 다수 발생하고 있다. 본 연구에서는 이러한 안전사고 예방을 위해 안전관리 실명제의 중요도 순위를 전문가 설문으로 도출하였다. 건설현장 전문가를 대상으로 AHP모형을 통해 중요도 분석한 결과 상위계층은 건설기계가 가장 중요하다고 보았으며, 하위계층의 안전시설물 관리에서는 개구부, 건설기계에서는 타워크레인, 관리실명제에서는 "산업안전보건법" 상에 의한 관리, 안전관리조직에서는 CEO의무가 가장 중요하다고 보았다. 안전관리실명제의 기대되는 역할은 중대재해처벌법이 예방에 힘쓰기 보다는 방어에 온힘을 다하느라 예방의 기능이 저하되고 있다. 이러한 역 기능을 바로잡기 위해 안전관리실명제는 중요하다.

Asset management is a complex and difficult field that requires insight into numerous variables and even human psychology. Thus, it has traditionally been the domain of professionals, and these services have been expensive to obtain. Changes are taking place in these markets, and the driving force is the digital revolution, so-called the fourth industrial revolution. Among them, the Robo-Advisor service using artificial intelligence technology is the highlight. The reason is that it is possible to popularize investment advisory services with convenient accessibility and low cost. This study aims to clarify what factors are critically important when selecting robo-advisors for service users and providers in Korea, and what perception differences exist in the selection factors between user and provider groups. The framework of the study was based on the marketing mix 4C model, and the design and analysis of the model used Delphi survey and AHP. Through the study design, 4 main criteria and 15 sub-criteria were derived, and the findings of the study are as follows. First, the importance of the four main criteria was in the order of customer needs > customer convenience > customer cost > customer communication for both groups. Second, looking at the 15 sub-criteria, it was found that investment purpose coverage, investment propensity coverage, fee level and accessibility factors were the most important. Third, when comparing between groups, the user group found that the fee level and accessibility factors were the most important, and the provider group recognized the investment purpose coverage and investment propensity coverage factors as important. This study derived useful implications in practice. First, when designing for the spread of the robo-advisor service, the basis for constructing a user-oriented system was prepared by considering the priority of importance according to the weight difference between the four main criteria and the 15 sub-criteria. In addition, the difference in priority of each sub-criteria shown in the group comparison and the cause of the sub-criteria with large weight differences were identified. In addition, it was suggested that it is very important to form a consensus to resolve the difference in perception of factors between those in charge of strategy and marketing and system development within the provider group. Academically, it is meaningful in that it is an early study that presented various perspectives and perspectives by deriving a number of robo-advisor selection factors. Through the findings of this study, it is expected that a successful user-oriented robo-advisor system can be built and spread in Korea to help users.

This paper focused on fading out the factors of design innovation. Based on the previous studies, several factors were extracted to be tested by Delphi method among 15 experts in the design area. Delphi test showed a convergent result after the second round of questioning. Design mind of managers was conceived as the most important factor among those tested. On the base of importance, capability of design company was the second and industrial design demand was the third. Even though design manpower, design infrastructure and innovation network were ranked below the 4th factors, the absolute differences between high ranked factors and low ranked ones were not much wide. So. relatively low ranked factors were not negligible at all to get a desirable success in design innovation. This study provides some insights for the success of design innovation. First of all, design innovation could be achieved only when factors tested on this study upgraded simultaneously together. Desirable effect could not expected by a simple support such as logo design or kind of simple measure.

This paper aims to develop an appropriate methodology for establishing an investment strategy for 'demonstration of artificial rainfall technology using UAV' and that include establishment of a technology classification, set of indicators for technology evaluation, suggestion of final key technology as a whole study area. It is designed to complement the latest research trend analysis results and expert committee opinions using quantitative analysis. The key indicators for technology evaluation consisted of three major items (activity, technology, marketability) and 10 detailed indicators. The AHP questionnaire was conducted to analyze the importance of indicators. As a result, it was analyzed that the attribute of the technology itself is most important, and the order of closeness to the implementation of the core function (centrality), feasibility (feasibility). Among the 16 technology groups, top investment priority groups were analyzed as ground seeding, artificial rainfall verification, spreading and diffusion of seeding material, artificial rainfall numerical modeling, and UAV sensor technology.
