Today, most of all the query processors in the world generally use the 'Pipelining' method to acquire fast response time (first record latency) and less memory usage. Each of the operator nodes in the Query Execution Plan (QEP) provides Open(), Next(), and Close() functions for their interface to facilitate the iterator mechanism. However, the embedded database systems for the mobile devices, based on the FLASH memory, usually require a function like Previous(), which returns the previous records from current position. It is because that, in the embedded environment, the mobile devices cannot fully provide it main memory to store all the query results. So, whenever needed the previously read records the user (program) should re-fetch the previous records using the Previous() function: the BACKWARD data fetch. In this paper, I introduce the 'Direction Switching Problem' caused by the Previous() function and suggest 'Block-wise Skipping' method to fully utilize the benefits of the block-based data transfer mechanism, which is widely accepted by most of the today's relational database management systems.

The objective of this study was to apply a dementia prevention program to the subjects who were suspected of dementia and test its effect. This study was one group pretest-posttest design. The dementia prevention program was applied for 20 weeks to the 19 subjects who were suspected of dementia after a screen test among 638 subjects enrolled in 10 senior citizen's centers in G city. The scores of self-efficacy, cognition, quality of life were measured before and after the program. The data collected were analyzed using a SPSS (statistical analysis system) program, and frequencies, averages and standard deviations were obtained. The differences of the scores of the pretest and posttest were analyzed with Mann-Whitney test and sign test. The results were as follows: 1. After the program, the average score of self-efficacy was increased from 75.31 (standard deviation 11.99) to 84.26 (standard deviation 13.92). 2. There are no differences between the average scores of physical and psychological quality of life, however, the average score of social quality of life was slightly increased from 2.25 (standard deviation 0.40) to 2.53 (standard deviation 0.43), and the overall score of social quality of life was low. 3. The average score of cognition was significantly increased from 21.00 (standard deviation 2.60) to 24.58 (standard deviation 3.37), thus, it was found that the program was effective to improve the cognition level. 4. The score differences of self-efficacy, quality of life, cognition between the pretest and posttest were statistically significant. 5. The score differences of quality of life between the pretest and posttest were found to be dependent on marital status, exercise and regular checkup yes or no. In conclusion, the program was effective to prevent the subjects suspected of dementia from dementia.

Purpose: This study aimed to investigate the perspective of consumers in healthcare services regarding patient safety. Methods: The study was a descriptive study using a self-reported questionnaire. The questionnaire was based on the Senior Empowerment and Advocacy in Patient Safety (SEAPS) questionnaire, which was designed to assess patient safety health beliefs. The survey was conducted online and a convenient sample of 302 adults participated in total. The reliability of the measurement (Cronbach's ${\alpha}$) was 0.758 in attitude (ATT), 0.546 in out-come efficacy (OE), 0.757 in self-efficacy (SE), and 0.703 in behaviors (BEH). Results: The average patient safety awareness score of the healthcare service consumers was 2.72 (ATT), 2.91 (OE), 2.87 (SE), and 2.27 (BEH). Our analysis indicated that there were no differences in ATT, BEH, or SE by gender, age, or education level. However, in OE and the total score of the four subscales, there were significant differences by age and gender. Correlations were identified between BEH and SE (r=0.409, p<.01), BEH and OE (r=0.202, p<.01), ATT and SE (r=0.358, p<.01), and OE and SE (r=0.241, p<.01). Conclusion: This study measured consumer perspectives concerning patient safety. The findings demonstrate the need for developing a measurement tool to assess consumer's perception of patient safety, considering Korean healthcare system and cultural context.

Most of the rural development projects for the welfare of residents are mainly new construction and remodeling projects for community buildings such as village halls and senior citizens. However, in the case of the construction industry, it has been studied that 23% of the total carbon dioxide emissions generated in Korea are generated in the building-related sector. (GGIC, 2015) In order to reduce the emission of environmental pollutants resulting from construction of rural community buildings, there is a need to establish a system for rural buildings by predicting the environmental impact. As a result of this study, the emissions of air pollutants from buildings in rural communities were analyzed by dividing into seven stages: material production, construction, operation, maintenance, demolition, recycling, and transportation activities related to disposal. As a result, 12 kg of carbon dioxide (CO), 0.06 kg of carbon monoxide (CO), 0.02 kg of methane (CH), 0.04 kg of nitrogen oxides (NO), 0.02 kg of sulfurous acid gas (SO), and non-methane volatile organics per 1m of buildings in rural communities It was analyzed that 0.02 kg of compound (NMVOC) and 0.00011 kg of nitrous oxide (NO) were released. This study proved that environmentally friendly design is possible with a quantitative methodology for the comparison of operating energy and air pollutant emissions through the design specification change based on the statement of the rural community building. It is considered that it can function as basic data for further research by collecting major structural changes and materials of rural community buildings.

This study analyzed all medical institutions located in the Yeongbuk area of Gangwon Province by dividing the use of medical institutions by "including nursing hospitals" and "excluding nursing hospitals" from 2003 to 2017. As a result, high blood pressure, dementia, musculoskeletal diseases, small-scale mechanical diseases, and other diseases were accounted for in the use of hospitalization for the elderly (including nursing hospitals) in the Yeongbuk region. In the case of hospitalization use of the elderly population (excluding nursing hospitals), blood and circulation machine diseases, digestive and urinary system diseases, mental diseases, and other diseases, including high blood pressure, were shown in the order. Therefore, the treatment and health care of the elderly are very important, and the expansion of public health organizations is necessary to establish governance with local medical institutions, organizations, universities, etc. Based on this, health projects should be carried out at a preventive level to maintain a healthy life for senior citizens in Yeongbuk, Gangwon-do.

The purposes of the present study were finding out educational implications and enhancing the efficient use of computer-based assessments (CBA) in class designes. This paper examined associations of CBA perceptional typology, academic achievement, personality, and computer efficacy. Participants were fifty senior students who took more than 50% of CBA classes in a university that introduces online learning-based system (LMS) with CBA. As a result, there were significant differences between CBA types and GPA and between CBA types and personality. In other words, the CBA adjustment type showed the highest GPA score and CBA dissatisfaction/paper test preference type showed the lowest GPA. Similarly, in terms of personality, CBA adjustment typology was significantly higher conscientiousness than other types. CBA dissatisfaction type had the lowest score of conscientiousness. In addition, the higher the level of conscientiousness, agreeableness and neuroticism, the higher the GPA score. This study is meaningful in that it is the first attempt to seek links CBA type with academic achievement and personality.

Background: It is not possible to measure how much activity is required to understand and code a medical data. We introduce an assessment method in clinical coding, and applied this method to neurosurgical terms. Methods: Coding activity consists of two stages. At first, the coders need to understand a presented medical term (informational activity). The second coding stage is about a navigating terminology browser to find a code that matches the concept (code-matching activity). Systematized Nomenclature of Medicine - Clinical Terms (SNOMED CT) was used for the coding system. A new computer application to record the trajectory of the computer mouse and record the usage time was programmed. Using this application, we measured the time that was spent. A senior neurosurgeon who has studied SNOMED CT has analyzed the accuracy of the input coding. This method was tested by five neurosurgical residents (NSRs) and five medical record administrators (MRAs), and 20 neurosurgical terms were used. Results: The mean accuracy of the NSR group was 89.33%, and the mean accuracy of the MRA group was 80% (p=0.024). The mean duration for total coding of the NSR group was 158.47 seconds, and the mean duration for total coding of the MRA group was 271.75 seconds (p=0.003). Conclusion: We proposed a method to analyze the clinical coding process. Through this method, it was possible to accurately calculate the time required for the coding. In neurosurgical terms, NSRs had shorter time to complete the coding and higher accuracy than MRAs.

Importance recognition of the nursing management(N. M.) clinical practice contents and the actual practical experience were studied against 289 students of 3 nursing schools who had undergone the senior N. M clinical practice. The most important item they considered from the practical evaluation was responsibility followed by interpersonal relationship, trust, communication, and ethic. For the importance of the N. M. contents, nursing unit management was considered as the most important(4.37/5). Abilities they could actually experience from the clinical practice were nursing unit management(22.0%), understanding of nursing management(20.7%), and human resource management(19.8%). And, abilities they could never experience were marketing(52.4%) and financial management(44.0%). Since there was an inconsistency between the importance of contents students recognized and the actual experience, I suggest a completion of standardized protocol of N. M. clinical training and implementation of management training exclusive preceptor system.
