Studies on the ship's automatic navigation & berthing control have been continued by way of solving the ship's mathematical model but the results of such studies have not reached to our satisfactory level due to its non-linear characteristics ar low speed. In this paper the authors propose a new berthing control system which can evaluate as closely as captain's decision-making by using the FNN(Fuzzy Neural Network) controller which can simulate captain's decision-making by using the FNN(Fuzzy neural Network) controller which can simulate captain's knowledge. This berthing controller consists of the navigation subsystem FNN controller and the berthing subsystem FNN controller. The learning data are drawn from Ship Handling Simulator (NavSim NMS90 MK III) and represent the ship motion characteristics internally According to learning procedure both FNN controllers can tune membership functions and identify fuzzy control rules automatically The verified results show the FNN controllers effective to incorporate captain's knowledge and experience of berthing.

On-Line optimization of process units has heretofore been restricted to the individual equipment level using linear approximate models. The advent of the low cost, high speed micro-computer coupled with the speed and robustness of an equation based exact simulator is making real-time optimization of entire process units a reality. The resultant implications for a decision system applied to day-to-day operations, point to a significant change in the way process plants will be managed in the future.

This study analyzed the degree of demand for genetically modified organisms(GMOs) to provide the basic information for consumers' reasonable purchase decision making and their right to know about GMOs. Based on the (Ed-there are no study results above) study results, the following suggestion were made. First, throughout the survey, it was found that those consumers who participated had a high level of perception on the harm of GMOs. Therefore, reliable organizations such as government agencies are required to present the results of safety tests and formulate plans related to the safety of GMOs. Second, the average score on consumers' level of consumer knowledge on GMOs was very low, being 1.68 out of a possible 8 points. Third, since women and housewives engaged in dietary habits and food had high demand for information on GMOs, it is necessary to provide women with information on GMOs. Fourth, since it is difficult to confirm the presence or absence of GMOs. in rapidly increasing demand for fast-food, it is necessary that consumers be provided with relevant information and make a reasonable judgement in purchasing food. Fifth, it is necessary to provide detailed regulations and measures for concrete contents and directions of information on GMOs. Sixth, it is necessary to provid information on GMOs from the commercial sources of information that are most preferred by consumers.

Consumer decisions and responses about the price to pay vary. Some consumers might decide the appropriate price range prior to shopping, while others compare and evaluate prices. Especially, consumers can have different reference points for price evaluation based on various price searching behavior that represent heterogeneous responses for prices in the clothing purchase decision-making process. This research identifies how consumers evaluate the price and helps explain their decision-making based on price searches. By analyzing qualitative research, we found that consumers recalled price information as a representative indicator and product level price information through the internal search. Their level of internal references can be an important factor affecting price evaluations. In addition, each consumer groups were subdivided into high and low external searching. The four types of responses to price were classified in the price search process and the identified differences in the price evaluation. Therefore, pricing strategy needs to be differentiated for these various consumer types.

We build middleware architecture with J2EE and LiveGraph to process different ubiquitous healthcare application's data and process that data into useful information, which can play a most important role in decision making in ubiquitous Healthcare System. Application developers mostly rely on third party middleware, tools and libraries (i.e., webservers, distributed middleware such as CORBA, etc.) to respond the emerging trends of their target domain. With this middleware we tried to enhance the efficiency of application by decrease their memory uses, data processing and decision making on another web module which is independent of each application. For middleware system, we proposed an algorithm by which we can find some important conclusion about different health status likewise ECG, Accelerometer. etc., which can be used in various data processing and determine the current health status. In this paper we also analyze some different low level and high level middleware technology which were used to build different kind middleware likewise CAMUS, MiLAN and try to find the best solution in the form of middleware for Ubiquitous Healthcare Information System.

한국 국회에 대한 낮은 국민신뢰도는 대화와 타협을 중시하는 의회의 구조적 특성에 기인한 독특한 의사결정과정에 일정부분 기인하고 있다는 점은 부인하기 어렵다. 그러나 이보다 더 중요한 요인은 한국의 유권자들이 전반적인 정치상황에 대해 부정적인 인식을 갖고 있고, 높은 정치적 효능감과 정치적 관심에 따른 기대수준을 한국의 국회가 제대로 충족시키지 못하고 있다는 점이다. 특히, 다른 민주주의 국가들과 비교해서 한국 유권자들이 보이는 높은 정치적 효능감과 정치적 관심은 의회와 민주주의에 대해 매우 긍정적인 평가로 연결되며, 이는 현실 정치체제에 대한 높은 기대치로 이어지고 있다. 문제는 높은 정치적 기대치가 현실의 상황에서 충족되지 못할 때 역시 높은 실망감으로 이어지기 쉽다는 점이며, 한국 국회에서 빈번히 관찰되는 파행적인 모습들이 국민들의 국회에 대한 실망감을 낳게 하는 요인이 되고 국회에 대한 낮은 국민신뢰도도 이의 연장선상에서 이해될 수 있다.

This paper considers the application of mobile robot to the herding problem. The herding problem involves a ‘pursuer’ trying to herd a moving ‘evader’ to a predefined location. In this paper, two mobile robots act as pursuer and evader in the fenced area, where the pursuer robot uses a fuzzy cooperative decision strategy (FCDS) in the herding algorithm. To herd evader robot to a predefined position, the pursuer robot calculates strategic herding point and then navigates to that point using FCDS. FCDS consists of a two-level hierarchy: low level motion descriptors and a high level coordinator. In order to optimize the FCDS, we use the multi­thread evolutionary programming algorithm. The proposed algorithm is implemented in the real mobile robot system and its performance is demonstrated using experimental results.

The purpose of this study was to identify the level of awareness, uses, and satisfaction on home automation systems by the digital home residents, to reveal the existing problems using home automation systems, and to clarify residents' positive or negative life changes after using home automation systems. Two apartment complexes, which were relatively well equipped with home automation systems compared to other recently built apartments, were selected to perform the survey by digital home residents who were housewives and have lived in current home more than 6 months. The researcher developed a survey questionnaire for each apartment complex and collected data from 501 residents from May to June, 2008. The results of the study found low awareness and low uses of remote control systems of electric appliances through a cellular phone or PC from outside. Also, the significant variables which showed group differences in level of uses and satisfation were age, annual income, duration of residence, and level of considering home automation system before decision to move in. The results of the study also revealed that frequent breakdown was the most critical problem using home automation systems. Generally, using home automation systems affected to residents' life changes positively. More findings and suggestions for development of more user-friendly digital home services were discussed.

Corporate culture is being recognized as essential managerial resources in the future business management and in recently the attempts, though weak, of developing the corporate culture which is corresponded with their own structure and needs are being carried on by some major companies. Then, corporate culture research, drawing attention in nowadays, indicates that it attempts to analyze and search the organization matters in the basical dimension in regard to the assumptions, values and beliefs of organization and provides the solution of organizational negative effects, which have not been settled in the previews research methods of organizational behavior, and that present turbulent management environment demands the whole conversion from the previews hard style to the soft managerial style. For this reason, this study aim at identifying organizational structure and corporate culture in the business group. Futhermore, the influence of organizational structure and organizational culture are examined. The objective of this paper attempts to analyze the ways and results of strong and special culture on the organizational structure and culture. To accomplish this purpose, this study gathers in-depth data form various secondary courses. First, uncertainties in market and technology are the main sources of mimetic isomorphism. Due to the high level of uncertainty is market and technologies. Smallness in size is responsible for the low level of complexity in organizational structure. The rapid changes in market, contents of service, and tastes of customers are responsible for the low level of formalization, which enhances swift decision making and responses.

Purpose: This study was aimed to investigate experiences, perceptions, and educational needs related to patient safety and the factors affecting these perceptions. Methods: Study design was a descriptive survey conducted in November 2019. A sample of 1,187 Koreans aged 20-80 years participated in the online survey. Based on previous research, the questionnaire used patient safety-related and educational requirement items, and the Patient Safety Perception Scale. Descriptive statistics and a decision tree analysis were performed using SPSS 25.0. Results: The average patient safety perception was 71.71 (± 9.21). Approximately 95.9% of the participants reported a need for patient safety education, and 88.0% answered that they would participate in such education. The most influential factors in the group with low patient safety perceptions were the recognition of patient safety activities, age, preference of accredited hospitals, experience of patient safety problems, and willingness to participate in patient safety education. Conclusion: It was confirmed that the vulnerable group for patient safety perception is not aware of patient safety activities and did not prefer an accredited hospital. To prevent patient safety accidents and establish a culture of patient safety, appropriate educational strategies must be provided to the general public.
