According to IMO, MASS is defined as a vessel operated at various levels independent of human interference. The safety navigation support service for MASS is designed to improve the safety and efficiency of MASS by developing public services on shore for ship arrivals/departures and for cargo handling. The safety navigation support service consists of a total of six types of services: autonomous operation, berthing/unberthing/mooring, cargo handling and ship arrival/departure service, PSC inspection, condition monitoring, and accident response support services. In order to support accident response service, the relative importance of a bridge navigational equipment was assessed by stratifying the navigation system to provide safe and efficient support services by objective judgment through specific and quantitative methods using AHP, one of decision-making methods used by an expert group. The survey was conducted by dividing the bridge navigational equipment into depth, location, and speed information. As a result of applying the AHP method, the importance of depth, location, and speed information was assessed. The relative importance of each equipment for providing location information was also assessed in order of Radar, DGPS, ECDIS, Gyro compass, Autopilot, and AIS. This was similar to survey results on the utilization of each operator's preference and its impact on marine accidents.

The main purposes of this study is to examine a local restaurants menus' importance and satisfaction of the servicescape. Survey was collected by December 1 through December 31 2015, in the region Kijang County. the data from this survey were analyzed by using various statistical techniques including frequency tables, factor analysis, reliability test, and IPA. Results of IPA analysis showed that menu consisted of local products is the highest average value, and it means the local food restaurants need to use the nostalgic marketing techniques. In addition, menus are currently for sale in order to attract continuing foreign tourists as perceived by Busan residents Kijang. Therefore, the local food restaurants need to revive the traditional flavors and recipes coming down area from ancient times. Based on these results, this study will contribute to provide fundamental information for developing marketing strategies especially local food restaurants.

The purpose of this study was to evaluate the importance and satisfaction level foreigners place on human and physical evidence service in Korean restaurants based on nationality such as American/European, Japanese, Chinese, and Southeast Asian. The research was performed by using questionnaires conducted from August to September on 365 foreigners living in Busan. Total mean scores for the importance (3.96/5.00) and satisfaction (3.33/5.00) of Korean restaurant human and physical evidence service were significantly different (p<0.01), as the gap was -0.63. The mean scores of the gap were -1.03 for cleanliness of dining area, -1.01 for cleanliness of tableware, and -0.95 for easily understandable menu board. The mean scores of satisfaction for Southeast Asian individuals (3.77) were significantly (p<0.01) higher than those of American/European (3.40), Chinese (3.37), and Japanese (2.81). The importance and satisfaction grid showed that an easily understandable menu board and a brief description of the food or menu scored high for the importance and low for the satisfaction in American/European, Chinese, and Japanese individuals. Cleanliness of the dining area, cleanliness of tableware, cleanliness of staff appearance, kindness of employees, rapid resolution of complaints, and prompt and quick service scored high for importance and low for satisfaction in Japanese. However, Southeast Asians were satisfied with human and physical evidence service of Korean restaurants.

네트워크 서비스에 있어서 품질을 정확히 측정하고 품질지수를 도출하는 것은 매우 중요하다. 종래의 네트워크 서비스에 대한 품질지수는 QoS(Quality of Service)로서 많은 연구가 있어왔다. 하지만 QosS를 통한 사용자 품질지수는 실제 사용자의 서비스 만족도를 효과적으로 표현해 주지 못하였다. 그래서 본 연구에서는 QoE(Quality of Experience)라는 개념을 도입하여, 사용자가 실제로 느낀 서비스의 만족도를 도출하고자 하였다. 사용자의 서비스 만족도를 잘 표현해주는 QoE를 도출하기 위하여 본 연구에서는 QoE Framework를 제안한다. QoE Framework는 framework를 위해 동작하는 agent들로 구성된다. QoE Framework의 agent는 크게 서비스 제공자측과 서비스 사용자 측으로 나눌 수 있는데, 서비스 사용자 측의 agent는 서비스를 이용하다가 사용자가 서비스 불만족을 감지하였을 때, 서비스 제공자측 agent는 사용자측 agent로부터 받은 서비스 불만족에 대한 feedback으로부터 QoE도출 알고리즘을 사용하여 최적의 QoE를 도출하는 기능을 한다. 서비스 제공자측 agent의 QoE도출 알고리즘으로 GA(Genetic Algorithm)을 사용하여 최적의 값을 구하게 된다. QoE framework의 알고리즘에서는 불만족 feedbaek을 이루는 QoS 파라미터들간의 중요도와 관계를 도출하여, 주어진 서비스 개선 비용으로 최적의 QoE를 도출함으로써, 네트워크 서비스에 대한 사용자의 만족도를 최대로 높이는 결과를 도출하게 된다.

In this study, IPA(Importance-Performance Analysis) techniques were used to suggest improvement plans and implications for convergent medical tourism services which medical tourists can be satisfied in Medical institutions. For this study, a total of 244 questionnaires among collected data for customers who experience a medical tourism service (a health checkup) at four hospitals located in Gangneung, Gangwon Province from September 1, 2014 to October 30, 2014 was to ensure a valid sample. As a result of the experiments which conducted by paired sample t-test analysis to learn corresponding to the difference between importance and satisfaction of the medical tourism services, it shows significant differences in all entries In the importance and satisfaction of the medical tourism services. As a result of the experiments which conducted by the IPA, the importance is high awareness but among service items which satisfaction is not actually high, service items that requires intensive care in the future are derived in items of "exact medical tourism services", "rapid response to the needs of the patient", "rapid medical tourism services", "communication with medical tourism coordinator". Therefore, medical institutions may need to be arranged in the Medical Tourism Coordinator with the agility and expertise of the medical tourism.

정보통신산업내의 경쟁이 심화되면서 과거의 독점 혹은 과점시장에서는 별로 중요하게 생각하지 않았던 서비스 요금 즉, 가격이 점차 중요한 기업내 의사결정요인으로 등장하고 있다. 이에 본 연구에서는 현재 통신서비스를 제공함에 있어 중요한 요소로 등장하고 있는 가격에 대하여 가격요인별로 소비자들의 의사결정에 얼마나 많은 영향을 미치는지 분석하고자 한다. 즉, 소비자가 서비스를 선택하는데 있어서 어떤 가격요인이 가장 큰 영향을 미치고, 가격요인 수준이 어떻게 변화하느냐에 따라 소비자가 느끼는 효용의 변화 크기는 어떻게 되느냐를 분석하고자 하는 것이다.

멀티미디어 기술을 이용한 최근의 각종 컴퓨터시스템과 정보통신 분야 서비스, 등에서 사용자 인터페이스가 시장을 점유할 수 있게 하는 가장 중요한 요소가 되고 있다. 특히 가전제품, 정보서비스, 개인용 컴퓨터 시장에서는 그 중요도가 더 부각된다. 그러나 세심한 주의를 하지 않고 다양한 매체를 일반 사용자가 사용하는 사용자 인터페이스에 적용하면 오히려 그 환경이 너무 복잡해서 사용자가 그 제품을 사용하기 불편하게 하거나 더 나아가 사용을 포기하게 할 수도 있다. 즉 새로운 기술을 제공하더라도 단순하며 사용하기 쉽도록 주의를 기울여야 한다. 이러한 우려에도 불구하고 정보통신용 사용자 인터페이스 분야는 급속히 발전되고 있다. 그러므로 본고에서는 멀티미디어 제품 및 서비스를 위해 HCL 측면에서 고려할 사항과 관련 기술을 살펴본다.

Although there are usual security threats caused by the characteristics of cloud services, more public institutions plan to introduce the cloud services rapidly, as the increase of recognition for its advantage. The previous studies have focused on the security threats and the quality as a hindrance of activation of cloud services. Those also have stressed the importance of the quality in the cloud user side. But there was no consideration about which quality factors impact on the satisfaction of users. Therefore, this study analyzed the importances of quality in specific five major factors. The results also presented that the SLA guarantee is more important than the security performance. This research will contribute to cloud services providers in Korea, by aiding the establishment of effective quality strategies.
