The purpose of this study is to diagnose the current states and the problems of student assessment of Elementary School Mathematics. For that purpose, this study conducted a survey and had the individual interviews. The surrey items consisted of the six main parts: questions about the development of assessment tools, the method to assess, the grading, the special supplementary courses, the opening of learning effect, and the follow-up guidances. The results of this study are as the follow First, elementary teachers depended heavily on internet sites for developing assessment problems. Second, elementary teachers made use of a performance assessment, a unit assessment, and a term examination at ordinary times. Third, unit assessment was largely referred for grading by elementary teachers. Fourth, in selecting the students for the special supplementary courses, both criterion-referenced assessment and norm-referenced assessment were considered. After finishing the special supplementary courses, additional tests were usually taken. Fifth, elementary teachers took a negative attitude in opening of learning effect. specialty opening of test paper to parents of students was done under 30%. Sixth, fellow-up guidances were the most through the classroom guidances. but consulting with parents of students was not frequently conducted by teachers.

Purpose: The purpose of the study was to provide deep understanding of the reported experiences of families with their loved one in the intensive care unit (ICU), focusing on interactions with healthcare providers. Methods: The data were collected by individual interviews of eleven participants. The transcribed data were analyzed using qualitative content analysis to identify major themes and sub-themes that represented the experiences of families. Results: Five themes and 13 sub-themes emerged. "Captive of patients' delayed death: Fear and anxiety" describes psychological problems arising when the family member became critically ill enough to warrant being admitted to the ICU. "Families as the weak: Suppression and resistance" describes interpersonal difficulties arising due to lack of information and trust with healthcare providers. "Deprivation of authority and duty as families: Helplessness" illustrate situational barriers in attempting to protect and support family member. "Re-establishment of trust relationship with healthcare providers: Gratitude and appreciation" describes how they satisfied with themselves by regaining trust relationship. Lastly, "Acceptance of reality through direct care participation: Relief and peace" illustrates peace of mind by gaining sense of reality through active direct care participation. Conclusion: This study demonstrates the positive and negative experiences of families with ICU patients. The results will be useful in developing family-centered nursing interventions.

Purpose: The aim of this study was to analyze Neonatal Intensive Care Unit nurses' behaviors while soothing newborns with bronchopulmonary dysplasia. Methods: An observational study was used to assess nurses' soothing behaviors. Data were collected from September, 2012 to March, 2013 using an audio-video recording system. Participants were eight babies and 12 nurses caring for those babies. After obtaining parental permission, the overall process of each episode from nurses' engagement in soothing to the end of soothing was recorded. Then a researcher interviewed each participating nurse. Data from 18 episodes were transcribed as verbal and nonverbal nursing behaviors and then categorized by two researchers. Results: There were 177 observed soothing behaviors which were classified with the five sensory-based categories (tactile, oral, visual, auditory, vestibular). Most frequently observed soothing behavior was 'Gently talking' followed by 'Removing irritant', and 'Providing non-nutritive sucking'. Nurses' perceived soothing behaviors were similar to the observed soothing behaviors except for 'Gently talking'. Conclusion: Nurses used diverse and mixed soothing behaviors as well as recognizing those behaviors as essential nursing skills. Nurses' soothing behaviors identified in this study can be used to comfort babies and to enhance their developmental potential in accordance with individual characterstics or cues.

Purpose: This study was conducted to provide an effective nursing intervention using an individualized educational program composed with knowledge, compliance, and physiologic parameters for long-term hemodialysis patients. Methods: A quasi-experimental study using a non-equivalent control group and pre- and post-test design was conducted with 40 hemodialysis patients at G university hospital in the J city from June to August, 2015. A data was analyzed using frequency, percentage, ${\chi}^2$ test, Shapiro-Wilk test, independent-samples t-test and repeated measures ANOVA using SPSS 21.0 program. Results: knowledge about hemodialysis and patient role behaviors were not significantly different between the two measures. In the biological index, there was significant difference between the groups by points in time and group in blood potassium, albumin, and Kt/v. However, there was no difference in gaining weight between hemodialysis, hemoglobin, and blood phosphorus. Conclusion: The individual training program in this study had an effect on changing some physiological indicators of long-term hemodialysis patients. Future research is warranted for developing various kinds of education program incorporating the findings of the study for the given population.

Among the semiconductor If-chips, unlike memory chips, a majority of Application Specific IC(ASIC) products are produced by customer orders, and meeting the customer specified due date is a critical issue for the case. However, to the one who understands the nature of semiconductor manufacturing, it does not take much effort to realize the difficulty of meeting the given specific production due dates. Due to its multi-layered feature of products, to be completed, a semiconductor product(called device) enters into the fabrication manufacturing process(FAB) repeatedly as many times as the number of the product specified layers, and fabrication processes of individual layers are composed with similar but not identical unit processes. The unit process called photo-lithography is the only process where every layer must pass through. This re-entrant feature of FAB makes predicting and planning of due date of an ordered batch of devices difficult. Parallel machines problem in the photo process, which is bottleneck process, is solved with restricted roll out algorithm. Roll out algorithm is a method of solving the problem by embedding it within a dynamic programming framework. Restricted roll out algorithm Is roll out algorithm that restricted alternative states to decrease the solving time and improve the result. Results of simulation test in condition as same as real FAB facilities show the effectiveness of the developed algorithm.

Clinical myography(EMG) is a technique for diagnosing neuromuscular disorders by analyzing the electrical signal that can be records by needle electrode during a muscular contraction. The EMG signal arises from electrical discharges that accompany the generation of force by groups of muscular fiber, and the analysis of EMG signal provides symptoms that can distinguish disorder of mLecle from disor- ders of nerve. One of the methods for analysis of EMG signal is to separate the individual discharge-the motor unit action potentials(MVAPS) - from EMG signal. But we can only observe the EMG signal that is a superimposed version of time delayed MUAPS. To obtain the information about MUAP(, i.e., position, firing number, magnitude etc), first of all, a method that can separate each MUAP from the EMG signal must be developed Although the methods for MUAP separation have been proposed by many researcherl they have required heavy computational burden. In this paper, we proposed a new method that has less computational burden and performs more reliable separation of superimposed EMG signal using wavelet filter which has multiresolution analysis as major property. As a result, we develope the separation algorithm of superimposed EMG signal which has less computational burden than any other researchers and exacutes exact separation process. The performance of this method has been discussed in the automatic resolving procedure which is neccessary to identify every firing of every motor unit from the EMG pattern.
