Flash memory has its unique characteristics: the write operation is much more costly than the read operation and in-place updating is not allowed. In this paper, we analyze how these characteristics of flash memory affect the performance of clustering and non-clustering in record management, and shows that non-clustering is more suitable in flash memory environment, which does not hold in disk environment. Also, we discuss the problems of the existing non-clustering method, and identify considerable designing factors of record management method in flash memory environment.

In similarity join processing, a general technique employs a generation-verification framework, which includes two phases: the first phase generates a set of candidate pairs from a collection of records; and the second phase verifies each candidate pair by computing real similarity. In order to reduce the number of candidate pairs in the verification phase, the median of one record of each candidate pair is used as a filter in this paper to test whether the other record can has the proper number of overlapped tokens. We propose a similarity join algorithm with the median filter, and show that the proposed algorithm has better performance in execution time than recent algorithms without the filter through extensive experiments on real-world datasets.

This study aims to analyze the factors of the extra-curricula area in personal school performance record and propose the practical strategies for entrance examination affairs on this area. To address this goal, we have applied a SWOT analysis with related documents and research results. We found out five strengths: (S1) Link the students' experience to right people for the university, (S2) Quantitative Indicators, (S3) Qualitative Indicators, (S4) Link to other evaluation factors, and (S5) Analysis of Human Resource. The weakness included: (W1) Fairness, (W2) Reliability, (W3) Difficulties to set standards, (W4) Difficulties to set environments, and (W5) Lack of systemic experience of an evaluation. We also discovered five opportunities (O1) Recognition of public education, (O2) The need of national support, (O3) The importance of autonomy, (O4) Specialization, and (O5) Networks. Finally, threat factors consisted of: (T1) Frequent change of educational policy, (T2) Increasing of private education, (T3) Lack of information and preparation time, and (T4) The accuracy and reliability of personal school records. Based on these results, we suggested practical strategies with these four dimensions: S-O, W-O, S-T, and W-T.

In this paper, an extended Cloud analysis method is developed for seismic fragility assessment of existing highway bridges in the southeast Queensland region. This method extends the original Cloud analysis dataset by performing scaled Cloud analyses. The original and scaled Cloud datasets are then paired to generate seismic fragility curves. The seismic hazard in this region is critically reviewed, and the ground motion records are selected for the time-history analysis based on various record selection criteria. A parametric highway bridge model is developed in the OpenSees analysis software, and a sampling technique is employed to quantify the uncertainties of highway bridges ubiquitous in this region. Technical recommendations are also given for the seismic performance evaluation of highway bridges in such low-to-moderate seismic zones. Finally, a probabilistic fragility study is conducted by performing a total of 8000 time-history analyses and representative bridge fragility curves are generated. It is illustrated that the seismic fragility curves generated by the proposed extended Cloud analysis method are in close agreement with those which are obtained by the rigorous incremental dynamic analysis method. Also, it reveals that more than 50% of highway bridges existing in southeast Queensland will be damaged subject to a peak ground acceleration of 0.14 g.

NGOs(Non-Governmental Organizations) are organization based on the 'voluntary participation' of citizens. Citizens' participation and support are essential for the existence and sustainable growth of the organization. The records of NGOs are produced, received, collected, and left behind in the course of their activities. Systematically managed records are used as information for business performance to increase operational efficiency. In addition, it plays a role in proving the legitimacy of the group and its activities to internal and external stakeholders of the NGO, such as whether the group's activities were performed legally and whether the group is actually working to realize the goal it stands for. Therefore record management of NGOs is required to improve accountability. In other words, NGOs can be gain the trust of civil society based on accountability through records and secure internal and external resources necessary for the existence of the group. In this study, after confirming the general record management status of NGOs in Busan, improvement measures were examined in terms of record management in order to increase the accountability of NGOs.

The electronystagmography(ENG) means to measure and record CRP(Corneal-Retinal Potential) whenever the eyeball is moved by using a skin electrode stuck to the hi-temporal and the difference of CRP. Both the horizontal and vertical movement are known according to the position of the stuck skin electrode. In this paper, the variable time-constances to record the eyeball signal of the conventional EOG(Electro-Oculograph) Amplifier is chosen. The shorter the time-constance is, the worse the distortion of a signal is. But the unbalanced impedance of the electrode stuck on the hi-temporal is reduced. Also, the longer the time-constance is, the less the distortion of it signal is. But it is sensitive to the change of base line according to the unbalanced impedance. In order to solve these problems, an DC-Amplifier, the distortion of the eyeball signal is globally used. By solving unbalanced impedance problem of EOG amplifier, the distortion ratio of EOG amplifier is improved.

The spectrum of impulse response signal which is obtained from an impulse hammer testing is used for frequency response function, nevertheless it has serious faults when the record length for the signal processing is not very long. The faults cannot be avoided with the conventional signal analyzer that is processing all the signals as if they are always periodic. The signals generated by the impact hammer are undoubtedly non-periodic because of the damping, and are acquired for limited recording time due to the memory as well as the computation performance of the signal analyzer. This paper will make clear the relation between the faults and the length of recording time, and propose the way for solving the faults.

Purpose: This study was conducted to examine the relationship among task interruption, task performance, and burn-out in nurses working at emergency room. Methods: The subjects of this study were 225 working at emergency rooms of 19 hospitals. Data was collected by using the structured questionnaire, including frequency of task interruption. problems in task performance due to interruption, and burn-out. Results: The average scores of task interruption were 2.06 due to communication, 1.49 due to treatment and record, and 1.39 due to other services (range 1-4). Frequency of task interruption was significantly correlated with task performance and burn-out. Conclusion: Emergency room nurses experienced some task interruption. The task interruption can influence upon task performance and burn-out of emergency room nurse.

Background: The appropriate management of diabetes mellitus(DM) can help reduce its relapse and economic burden, but the level of management of DM in Korea is reported to be insufficient. This study aims to identify the management level of DM by figuring out the HbA1c examination performance rate of the diabetics and analyzing the variation according to the characteristic of a diabetic. Methods: This study used the Korean National Health Insurance Database which includes E10-14(ICD-10 code) as a primary or secondary disease as of 2006. Study population is 1,892,062 diabetics excluding 393,784 patients with the first attack of DM in 2006, 33,440 diabetics who died in 2006, and 21,299 patients with DM having no record of ambulatory care among the 2,340,585 DM patients in total. Results: The HbA1c examination performance rate of all DM patients in our country is estimated to be 41.5% as of 2006 and shows variation according to the characteristic of individual DM patients. The highest performance odds was shown by the patients who were below 19 of age, insured for health insurance, attended more than 3 ambulatory care providers, made ambulatory care visits more than 10 times annually, attended a specialized general hospital as their main attending medical institution, had a record of hospitalization or had co-morbidity. Conclusion: This study propose that is necessary to make politic preparations for the appropriate management of diabetes at a national level, and particularly, the patients with advanced age, the ones dependent on Medical Aid, and the ones using hospitals or clinics, whose appropriate management seems vulnerable, demand a careful management.

This study was conducted to analyze the lap time of the K-1 1000m final race of men's general division and to develop strategies to adjust the pace for the intervals to improve the performance. We measured the lap time of the final race of the 99 th National Sports Festival by 250m intervals and compared them with the data of the World Championship finals held in 2018. The final average record of domestic top-ranked players was 248.651 seconds, and the top international's 210.826 seconds. There was a time gap of 38 seconds in the record. In lap-time, it was 8, 11, 6, and 13 seconds behind every 250m. World Championship players used the Fast-Maintain-Maintain-Spurt strategy while domestic players used the pacing strategy of Fast-Slow-Fast-Slow. In order to improve the performance of domestic players, it is necessary to adjust overall pace control strategies to maintain the pace after the quick start and to spurt at the last lap.
