As a simple and practicable method, an Importance-Performance Analysis(IPA) is often used as a tool to study the satisfaction of tourists in Tourism. The IPA has two dimensions to attribute importance and performance(or satisfaction as in satisfaction research), and generally uses an interviewee self-reported approach to acquire performance and importance data. Many scholars have pointed out that the traditional IPA cannot meet the premise of its establishment. Therefore, several revised IPA have been proposed. Among them, Deng's IPA is the most representative. There are not many contrastive analyses between the traditional IPA and revised IPA in academia. The lack of comparative study will make it difficult to judge the difference and effectiveness of different IPA techniques. Taking Gyeongju Yangdong Village as an example, this study investigated and researched the degree of satisfaction of Chinese tourists using the traditional IPA method and Deng's modified IPA method respectively, and then analysed the differences between the two methods and their causes. Based on the analysis results, the study put forward suggestions for the improvement of tourism management in Gyeongju Yangdong Village.

This study empirically examines the relationship between the characteristics of a company and its performance through open innovation. It was intended to accept open innovation as a strategic means to overcome various situations in which companies faced and to understand it as a process of generating corporate performance. In various situations, companies must overcome environmental and internal factors. As an environmental factor, the dynamics of the market and the dynamics of technology allow for the adoption of open innovation, which in turn becomes a strategic tool for generating results. In addition, the internal environment of the company should strengthen the organization's capacity considering the characteristics of the company. In order to reinforce entrepreneurial orientation, openness of organizational culture, delegation and R & D capabilities, which are internal characteristics of the company, open innovation has a positive effect on the performance of the company. In overcoming the environment given to the company, open innovation was found to be an important medium for generating various results for the company. For this study, we conducted a structured questionnaire survey on 176 Korean companies. This study suggests that open innovation is strategically accepted and understood as a management strategic philosophy in order to overcome the environment in which a company is faced and generate results.

SSI instruction can be an effective tool to promote key competencies for future citizens. Our assumption of the study is that applying the concept of collective intelligence in the context of SSI learning would facilitate the learning. Thus, we designed and implemented Collective Intelligence-based SSI instruction over almost a year and observed the effects of the instruction on enhancing students' collaboration, information management, critical thinking, and communication skills. Twenty 9th grade students enrolled in a science-gifted program voluntarily participated. Data was collected by administering a questionnaire to examine the skills before, in the middle of, and after the instruction, and by conducting classroom observations and focus student group interviews. The results indicated some degree of improvement in their targeted skills. First, they experienced the expansion of their thoughts by actively sharing information and ideas using the web platform. Second, they became more flexible and open to different points of views in order to accomplish a common goal. Third, they appreciated having independent time and space to explore their own positions on the issues and to search necessary information, and believed that the process encouraged them to more pro-actively participate and communicate in the group debates. Lastly, they positively perceived the values that collaboration with diverse group members could produce.

Recently, the number of disasters has been seriously increasing. The total damages by the natural or man-made disasters during the past years resulted in tremendous fatalities and recovery costs. It is necessary to have efficient emergency evacuation management which is concerned with identifying evacuation route, and the estimation of evacuation and clearance times. An emergency evacuation model is important in identifying critical locations, and developing various evacuation strategies. In that existing evacuation models have focused on route analysis for indoor evacuation, there are only a few models for areawide emergency evacuation analysis. Therefore, we developed a mesoscopic model by using Cube Avenue and performed evacuation simulation, targeting road network in City of Fargo, North Dakota. Consequently, a mesoscopic model developed in this study is used to carry out dynamic analysis using network and input variable of existing travel demand model. The results of this study show that the model is an appropriate tool for areawide emergency evacuation analysis to save time and cost. Henceforth, the results of this study can be applied to develop a disaster evacuation model which can be used for a variety of disaster simulation and evaluation based on scenarios in the local metropolitan area.

Objective : As treatments for breast cancer require long period of time, the patients need continuous monitoring and management of their health related quality of life. The purpose of this preliminary study is to explore the utility of monitoring quality of life using a mobile phone based application, which was developed to enable the patients to report daily quality of life more efficiently. Methods : Department of psychiatry, breast cancer center and U-health team of Asan Medical Center collaborated in developing a mobile application titled 'DugunDugun'. Through the application, patients with breast cancer receiving neo-adjuvant chemotherapy could report on various questions about their daily quality of life. We extracted and explored the daily basis of the data of sleep duration, number of awake, sleep satisfaction, mood and anxiety from nine patients who reported on the questionnaire for more than a month. Results : The longitudinal data collected using our mobile application well represented the characteristics of individual sleep patterns and daily emotional changes. Most of the patients showed high daily variations in the scores of their quality of life while their averaged scores were similar among patients. The patient with highest daily variations in the subjective sleep quality and daily emotional change had highest score corresponding to moderate depression in Beck Depression Inventory (BDI). Conclusion : The results suggest that mobile application could be a useful tool for monitoring and collecting the daily quality of life in the patients with breast cancer. We expect that mobile application could facilitate early detection and proper intervention for the cancer patients at psychological crisis.

Purpose: This study was conducted to examine the knowledge level and assessment experience of nurses in regards to delirium, and to utilize the study results as baseline data for planning delirium education programs for nurses. Methods: Subjects were 465 nurses who were working in a general hospital. A 'delirium related knowledge and assessment experience' questionnaire was used to collect data. Results: Knowledge levels regarding delirium averaged 70 out of 100, and at each domain, they scored 87 for etiology of delirium, 62 for symptoms, and 69 for nursing management. The knowledge level of delirium was significantly different according to educational level (F=3.851, p=.022), past education related to geriatrics(t=2.471, p=.014), and awareness of need for in-service education on geriatric nursing(F=2.663, p=.032). About 85% of nurses had past experience of dealing with delirious patients and only 7.7% of nurses used delirious state assessment tools. Conclusion: According to the above results, it is necessary, not only to provide delirium related educational programs for nurses, but also to emphasize the usefulness of applying the assessment tool.

The purpose of this study is to measure and analyze primary causes of indoor air pollution, including carbon dioxide, minute dust, and total volatile organic compounds, for each room before the beginning of a class through the time of discharge after the end of the class in general classrooms, computer rooms, and science rooms of three newly-established schools that opened in 2006, examine properties of indoor air environment in each room by educational activities at school, and determine effective management schemes; the results of this study can be summarized as follows: 1) As for implications for each item found in the mean for each place, since minute dust (PM10) was more likely to occur in time slots full of students' activities, such as a traveling class and a recess, than in the middle of a class and could be expected fully, it is necessary to make a scheme for cleaning in order to reduce minute dust within a room, for example, by usually using a vacuum cleaner indoors. 2) While carbon dioxide was expected to vary with the differences in the amount of breath between higher-graders and lower-graders in a general classroom but showed insignificant difference by grades, showing differences in pollution by four times at a maximum according to the opening of a window as expected, it is necessary to implement artificial or natural ventilation and take a positive measure, for example, by presenting a concrete ventilation scheme, in order to improve indoor air pollution at a room practice. 3) Total volatile organic compounds were found to exceed the standard by more than twice in general classrooms, science rooms, and computer rooms of the schools because of building materials, furnitures including desks and chairs, panels and boards for environment beautification, and items which could be detected even from students' clothes; while a field directly-reading tool was used, obtaining high reliability for the results, it is necessary to apply an analytical method based on process test separately for actual correct measurement if a significantly great amount of total volatile organic compounds appear as compared with other schools due to measuring expenses and consecutive measurements. 4) Since formaldehyde (HCHO) was generally found to exceed the standard in general classrooms, science rooms, and computer rooms, it is necessary to establish and operate a ventilator during a class in a computer room which requires airtightness and a science room in which an organic compound should be used for a class.

Petroleum reservoir characterization is a process for quantitatively describing various reservoir properties in spatial variability using all the available field data. Porosity and permeability are the two fundamental reservoir properties which relate to the amount of fluid contained in a reservoir and its ability to flow. These properties have a significant impact on petroleum fields operations and reservoir management. In un-cored intervals and well of heterogeneous formation, porosity and permeability estimation from conventional well logs has a difficult and complex problem to solve by conventional statistical methods. This paper suggests an intelligent technique using fuzzy logic and neural network to determine reservoir properties from well logs. Fuzzy curve analysis based on fuzzy logics is used for selecting the best related well logs with core porosity and permeability data. Neural network is used as a nonlinear regression method to develop transformation between the selected well logs and core analysis data. The intelligent technique is demonstrated with an application to the well data in offshore Korea. The results show that this technique can make more accurate and reliable properties estimation compared with previously used methods. The intelligent technique can be utilized a powerful tool for reservoir characterization from well logs in oil and natural gas development projects.

Objectives : This study is aimed to help the dental hygiene department students to improve their adaptive ability to the field work by letting them know the performing levels required of the job world, by renovating the knowledge-centered curriculum, and by finding out the core competencies needed for successfully performing their duties and tasks in the work field. Methods : The survey tool was recomposed through the examination of the preceeding studies on basic vocational competencies and skills, and the survey has been done to 200 dentists in Seoul and Gyunggi provice. Results : 1. As for the job-getting routs, 35.1% of them finds their jobs through the job portal sites, and 21.3% through the recommendation by professors. So we can see the meaningful difference in the employment ways. 2. Dental hygiene clinics think that the purpose of their cooperation with the colleges is mainly to secure human resources by requiring the colleges to give field-centered education the colleges through. 3. The clinics for dental hygienic students' field learning have a great power for hiring the students. So it is necessary to set up a good management system of the clinics for dental hygienic students' field learning in order to reinforce the students' competitive power in getting jobs. 4. The priorities in basic working abilities needed for the task performance are in the order of vocational responsibility, self-managing & developing ability, interpersonal skill, and problem solving ability. 5. The core competencies required of those who graduate from dental hygiene school show the following scores by Likert measurement; good personality and vocational consciousness 2.16(${\pm}.677$), understanding power of major-related knowledge 2.19(${\pm}.723$), field adapting ability 2.31(${\pm}.748$), get-along-with ability 2.32(${\pm}.799$), interpersonal skill 2.42(${\pm}.768$), and self-development ability such as getting certificates 2.43(${\pm}.729$). Among the core competencies, the only meaningful factor which influences on their satisfaction measurement has been identified as the professional ability related to the major. Conclusions : The results suggest that the knowledge and skill related to the major are core competencies of able human resources and closely related with the professionality of the job, and so they are very important. However, job basic abilities are also proved to be important, which reinforce the students' activeness, self-regulation, and creativeness, and help them to pursue their lasting growth in their abilities.
