Nowadays, the amount of image data increase explosively. To manage the large amount of image data efficiently, high-dimensional index structures are necessary. However, as my knowledge none of existing DBMSs supports high-dimensional index structures as access methods of DBMSs. In this paper, we design and implement CIR-Tree as a access method for retrieving image data effectively on the MiDAS-III that is the storage subsystem of the BADA-III. The implemented CIR-Tree manager shows much better retrieval performance than sequential search in performance evaluation.

As the development of wireless environment and portable devices, navigation companies need more spatial information for Location Based Service and so they are investing heavily in this part. But my country have constructed lots of spatial dataset during the NGIS project, and then we can reduce costs by using constructed spatial dataset. The integration method of each building information between e-AIS and KLIS-rn is linked to designed mapping table by main building numbers and auxiliary cadastral number. e-AIS and KLIS-rn are integrated by the feature matching between CAD data and KLIS-rn. Due to the limitation of test data, more accuracy test will be required with various data sets.

Purpose: This study was done to explore the essence and meaning of the experience of 'aging', as a process of 40's and 50's women in Korea by applying the Parse's Human Becoming theory (2002). Methods: Data was collected from February to April, 2013, using the phenomenological research method. Data was collected through in-depth informal interview and analyzed following Colaizzi method. After IRB permission and informed consent from the participants, all interviews were recorded with MP3 recorder and transcribed for analysis. Results: Data analysis revealed 112 of meanings, 33 key subject words, 8 subject phrases, and 4 categories. The main themes were elaborated as 'going down' ('Being changed of body and mind', 'Being considered on my identity'), 'going up' ('Being expanded of productive role', 'Being transcendent multi-dimensionally'), 'pausing' ('Becoming more thoughtful about family', 'Looking back'), 'going forward again' ('Age is just a number, 'Contemplating of life and death'). Experiences in aging among women in 40's and 50's enlightened with Parse's theory of Human Becoming in terms of 'going down', 'going up', 'pausing', 'going forward again' appeared simultaneously, rather than consecutively. Conclusion: Women in 40's and 50's require holistic nursing intervention with physical, psychological, socio-economical, and spiritual aspects, rather than focusing on problematic physical symptom relief and prevention of further conditions. It is recommended to develop various nursing intervention considering on different environment, type of experience, and level of human becoming, individually.

Purpose: The purpose of this study was to explore the components and nature of happiness in middle-aged women in Korea. Methods: Thirty middle-aged women living in metropolitan Seoul and Gyeonggi and Chungcheong provinces agreed to participate in this study. The data were collected through in-depth interviews with the participants in one-on-one settings. The data were analyzed qualitative using Colaizzi's method of phenomenology. Results: The three theme clusters were extracted from the raw data, along with 13 themes and 138 meaningful sentences and phrases. The three happiness theme clusters in middle-aged women were "live healthy for stability," "rule one's mind for harmony," and "activate hopes for self-esteem." The first theme cluster included healthy life, economic stability, physical youth, and positive thought. The second theme cluster included that harmonious family, ruling of mind, my position as invisible person in social relationships, and precious relationships to support. The last theme included the center of one's life is oneself, a sense of accomplishment, self-improvement, recognition of one's worth and rest for one self. The three theme clusters were associated with the existence, relatedness, and growth (ERG) of ERG areas, respectively. Conclusions: We conclude that the core components of happiness in middle-aged women are to live healthy and mind-ruled and activate hope. The nature of happiness is egocentric stability in middle-aged women. The results suggest that theme clusters might be used to develop a scale for measuring happiness in middle-aged women. This will be helpful to assess the psychosocial status of middle-aged women in Korea.

The purpose of this study is to investigate in depth the lived employers experiences of utilizing employment among people with mentally disabilities. Phenomenological approach was used for this study. A total of 9 employer on work of the mentally disabled people were recruited as research participants Data was collected through in-depth interviews from March, 2017 to September, 2018. Transcribed data from audio recordings on interviews were analyzed using the Braun & Clarke method. 6 clustered themes consisting of 12 sub-themes emerged through the qualitative data analysis and they include the following: 1) Getting to realize that a vague concern; 2) Being forced to withstand others' persuasion; 3) Fluctuating on boundaries of my work; 4) Moving forward from individual to team; 5) Being together work expected workers with mentally disabled; and 6) Seeking for company progress. Study findings suggest that expanding employment and improving its quality for work of the mentally disabled people are needed. Additionally, the field of mental health needs an increase in the experiences of employment with expertise in dealing with employers on work of the mentally disabled people.

Purpose: This study used a descriptive investigative design to identify educational needs for developmental supportive care for the purpose of establishing a developmental supportive care education program for nurses in neonatal intensive care units. Methods: A survey was conducted on 93 nurses working in neonatal intensive care units located in a metropolitan area, and the collected data were analyzed using descriptive statistics and a paired t-test with the SPSS 25.0 program. For the purpose of analyzing educational needs, we further analyzed data through an importance-performance analysis (IPA) and the Borich needs assessment and the locus for focus models. Results: The average importance of the developmental supportive care of nurses in neonatal intensive care units was 3.74±0.78 out of 5, and the average performance was 3.46±0.81 out of 5. A t-test on the difference between the IPA and Borich needs assessment showed the highest educational need in the categories of 'individualized care', and 'I serve on the Developmental Care Committee at my institution'. In addition, according to the results of deriving the priorities of educational needs using the Borich needs assessment and the locus for focus model, the highest priority was 'I provide appropriate pain management when noxious procedures are necessary'. Conclusion: These findings can be used as basic data to design a developmental supportive care program suitable for nurses in neonatal intensive care units to meet the educational needs for developmental supportive care.

The purpose is van Manen's interpretation of verbal violence experienced by nursing students during their growing up period in order to use it as basic data to improve the verbal communication essential for solving nursing problems and performing tasks with guardians and peers. For this, 10 students enrolled in the nursing department of A University in Gyeonggi-do were selected and data were collected through in-depth interviews. Data analysis conducted an existential inquiry process to focus on the essence of experience. Five thematic statements in this study were as follows: 'Beginning with a trivial conversation', 'Getting confused mind', 'Being an opportunity to reflect on myself', 'Changing the frame of my thought' and 'Making a mature me'. As a result, it confirmed the necessity of strengthening language usage and personal competency that respect the other party. Therefore, it is suggested that follow-up studies on empathy or self-positive effects are needed for effective communication techniques.

The management of data on biological diversity is presently complex and confusing. This study was initiated to construct a database so that such data could be stored in a data management, and analysis instrument to correct the problems inherent in the current incoherent storage methods. MySQL was used in DBMS(DataBase Management System), and the program was basically produced using Java technology Also, the program was developed so people could adapt to the requirements that are changing every minute. We hope this was accomplished by modifying easily and quickly the advanced programming technology and patterns. To this end, an effective and flexible database schema was devised to store and analyze diversity databases. Even users with no knowledge of databases should be able to access this management instrument and easily manage the database through the World Wide Web. On a basis of databases stored in this manner, it could become routinely used for various databases using this analysis instrument supplied on the World Wide Web. Supplying the derived results by using a simple table and making results visible using simple charts, researchers could easily adapt these methods to various data analyses. As the diversity data was stored in a database, not in a general file, this study makes the precise, error-free and high -quality storage in a consistent manner. The methods proposed here should also minimize the errors that might appear in each data search, data movement, or data conversion by supplying management instrumentation on the Web. Also, this study was to deduce the various results to the level we required and execute the comparative analysis without the lengthy time necessary to supply the analytical instrument with similar results as provided by various other methods of analysis. The results of this research may be summerized as follows: 1)This study suggests methods of storage by giving consistency to diversity data. 2)This study prepared a suggested foundation for comparative analysis of various data. 3)It may suggest further research, which could lead to more and better standardization of diversity data and to better methods for predicting changes in species diversity.

In order to know the characteristics of circadian rhythms in core temperature in tropical inhabitants, we measured rectal temperatures every 10 min for 24 hrs in 6 Vietnamese, 20 - 22 yrs (5 males and I females) under natural conditions. Average light intensity was 16000 lx. Ambient temperatures ranged from 33 to 36 oC. These data obtained were compared with those in Japanese setters and the Polish inhabitants. The participants were sitting mostly during wakefulness and lying in bed during sleep. The results obtained are summarized as follows: I) The average maximum value was 37.7 oC, which was significantly higher than in the Japanese and Polish as well. 2) The average minimum value was 36.4 oC, which was also lower. 3) A range of oscillation was 1.3 oC, which was clearly greater than in the people living in the temperate areas. The higher maximum value of core temperature, which was actively regulated under warm temperature, seemed of adaptive significance in order to reduce water consumption. A greater rage of oscillation in tropical Vietnamese people might have ecological significance for efficient acclimatization in the environment with strong light intensity and high ambient temperature, suggesting that the setpoint of core temperature could show a greater range of oscillation.
