Purpose: The purpose of this study is to examine nurses' turnover experiences and to provide basic information for developing turnover intervention program for effective human resources management. Methods: This study is an inductive, descriptive phenomenological research that uses profound interviews and observations. The subjects of the study were nurses retired from a hospital. Results: The themes were classified into the three theme clusters. The first theme was about 'deepening inside wound' which was described as experiencing stresses due to introversion, feeling a heavy burden about responsibilities as experienced nurses, feeling guilty about limits of performance and hurt about reproaches by seniors and having conflicts with physicians. The second theme cluster focused on 'powerlessness as time goes', which was stated as having difficulty in adaptation to the new rotated wards, feeling tired and having no spare time and difficulty in night duty, experiencing stagnation and powerlessness and feeling disappointed about inadequate rewards. The third was about 'can't find the exit' which were expressed with wanting to change the speciality because of concerns about future, having affection to motherhood, feeling conflict over the nursing profession itself, concentrating on the matter of turnover and facing related personal situations, and regretting turnover. Conclusion & Suggestions: Considering all these experiences, field managers in nursing should build up a support system that helps nurses overcome risks related to decision-making about turnover. In addition, nurse managers need to develop a human resources development program in which competent nurses are continuously won over through education and counseling.

This study investigated and analyzed the topographic landscape resources of Mureung Valley in Donghae-si from the viewpoint of geotourism in order to suggest the tourism contents and tour course. A total of 29 topographic landscapes were observed; these are broadly divided into 4 features including weathering landform, mountainous landform, fluvial landform, and structural landform. Major topographies are fluvial landform (13) and weathering landform (12). At least 19 topographies (14 sites, 19 topographic landscapes) are currently used as tourism resources, with 10 topographies having potential to be developed as new tourism resources. The 10 topographic landscapes are as follows: (1) Jamryong Bawi (Hidden Dragon Rock), (2) Janggipan Bawi (Korean Chessboard Rock), (3) Nurungji Bawi (Parched Rice Rock), (4) Damjang Bawi (Fence Rock), (5) Gyedan Bawi (Stairs Rock), (6) Heundeul Bawi (Rocking Rock), (7) Jeopsi Bawi (Dish Rock), (8) Dol Umul (Stone Well), (9) Jogak Bawi (Carved Rock), and (10) Dubu Bawi (Topu Rock). The topographic tour course can be divided into 3 routes considering accessibility and time. Route 1 is a basic one that anyone can easily use; Route 2 and 3 can be used by visitors who have more time to spare or who are more active.

This study was conducted to identify the interest, needs, and preferences for forest healing programs of patients with chronic diseases. A total of 227 individuals with chronic diseases who were admitted to a university hospital were surveyed on the needs and preferences of forest healing programs. The participants of this study were 111 patients (48.9%) with cardiovascular disease, 88 patients (38.8%) with gastrointestinal diseases, 39 patients with musculoskeletal disease (17.2%), and 78 patients (34.3%) with other diseases. About 51% of all participants had heard of the forest healing programs, but 94.3% of the participants said they had no experience in participating. The frequency of forest visits was the most often once a month or not, and the reason for not being able to participate in forest healing programs was "because there was no time to spare." The participants generally preferred a small group programs with family members or their friends for one day or two days. The preferred seasons were spring and autumn, and the preferred time zones were morning and weekend, and the participants preferred outdoor programs rather than indoors. An important factors of the programs were dense forests, trees, landscape, sound, and fresh air. These preferences can be applied when developing forest healing programs for patients with chronic diseases.

The purpose of this study is to make it easier, more fun and more convenient to learn a foreign language through the development of an efficient audio contents platform that utilizes each person's native language ability. In order to achieve the goal to produce audio contents centering on the native language used in real life. Contents that are created without much effort in daily life could be used as precious contents for foreign language learners to learn the natural use of the language. Currently, most of the online foreign language learning platforms have problems with the contents depletion and the low practicality of contents. Accordingly, I am expecting this platform improves the existing shortcomings, giving foreign language learners the opportunity to learn a foreign language more realistically and at the same time giving native speakers an opportunity to generate additional revenue by utilizing their spare time.

The development and speed improvement of the Internet network, and the development of many platforms based on it, have brought about a rapid expansion of production and consumption of various contents. However, the existing IP-based Internet system cannot efficiently cope with such an urgent increase in data. Accordingly, an alternative called the CCN(Contents Centric Network) has emerged, enabling more efficient data transmission and reception centered on content rather than host. In this paper, we will deal with the mobility of intermediate nodes in CCN real-time streaming service, which is one of the major research fields of CCN, and minimize network overload through more efficient path switching through RSSI detection. In other words, by improving the method of selecting and switching a spare path when an intermediate node located between the requester(consumer) and the provider moves, a mechanism for managing data transmission is not interrupted and unnecessary load due to route switching does not occur in the network.

This study provided safe sailing speed and appropriate passing time to areas of known strong current water to prevent marine accident of the ships. To the interpretation of these data which target Myeongnyang waterway, AIS data of the ship was collected from $12^{th}$ July to $15^{th}$ July 2010 and site environment was investigated on $4^{th}$ September 2010. On the basis of the collected data, the 'Minimum Navigation Speed' and 'Optimum Navigation Speed' were calculated. It has also considered the 'Spare control force' or allowance and the 'Respond Rudder Angle' for each tidal current speed. Additionally, it suggested the safe passing time to strong current area by analyzing tidal level and tidal current speed. The conclusion of the research are as follows : (1) If the flow rate is greater than 4.4 kn, it is difficult for the model ship to control herself by her own steering power and to cope with tidal current pressure force and yaw moment caused by the tidal current.. (2) The minimum navigation speed should be over 2.3 times the tidal current and the optimum navigation speed should be over 4.0 times the tidal current. (3) When spring tide, the optimum passing time at Myeongnyang waterway is between 30 minutes to 1 hour before the time of high/low water, and at 5 hours after high/low water, passing of ships should be avoided because it is time when the flow rate is over 4 kn.

This study aims to develop materials related to math education for the aged and to identify the effects of application as part of active measures to the aging society with its growing elderly population which is one of the greatest changes in our society. In this purpose, the necessity and objectives for development of materials of 'Silver Math' as education for the aged are explained. Developing and disseminating materials with a role as a program for intelligent needs and physical and spiritual health of the aged presents standards for development of more systemic and meaningful educational materials at this point of time when the importance of education of the aged increases to help the old enjoy qualitatively successful lives in later years in the perspective of lifelong education. Also it aims to present standards of contents and requirements in learning that are adequate and meaningful to old learners at the actual learning sites where education takes place only in terms of making good use of spare time while at the same time suggesting plans of teaching and learning as well as conditions for learning environment. Next, the effectiveness of 'Silver Math' are explored by applying developed materials to the aged. materials of 'Silver Math' for the aged with contents that are appropriate to the definitive and cognitive level of the aged are presented. The developed materials for mathematical activities are divided into 'computation of basic numbers' for those wishing to learn calculation and concepts of numbers, 'active math' that corresponds to definitive factors of old learners, facilitates leisure time through mathematical activities, and Improves communication abilities through cooperative learning among learners, and 'math with thinking power' to solve simple calculation problems by applying to various actual situations.
