Hypoxia-inducible factor $1{\alpha}\;(HIF1{\alpha})$ is a transcription factor that plays a key role in the adaptation of cells to low oxygen stress and oxygen homeostasis. The oxygen-dependent degradation (ODD) domain of $HIF1{\alpha}$ is responsible for the negative regulation of $HIF1{\alpha}$ in normoxia. The interactions of the $HIF1{\alpha}$ ODD domain with partner proteins such as von Hippel-Lindau tumor suppressor (pVHL) and p53 are mediated by two sequence motifs, the N- and C-terminal ODD(NODD and CODD). Multiple sequence alignment with $HIF1{\alpha}$ homologs from human, monkey, pig, rat, mouse, chicken, frog, and zebrafish has demonstrated that the NODD and CODD motifs have noticeably high conservation of the primary sequence across different species and isoforms. In this study, we carried out molecular dynamics simulation of the structure of the $HIF1{\alpha}$ CODD motif in complex with the p53 DNA-binding domain (DBD). The structure reveals specific functional roles of highly conserved residues in the CODD sequence motif of $HIF1{\alpha}$ for the recognition of p53.

Hypoxia-inducible factor $1{\alpha}$ ($HIF1{\alpha}$) is a transcription factor that plays a key role in the adaptation of cells to low oxygen stress and oxygen homeostasis. The oxygen-dependent degradation (ODD) domain of $HIF1{\alpha}$ responsible for the negative regulation of $HIF1{\alpha}$ in normoxia is intrinsically unfolded. Here, we carried out the backbone $^1H$, $^{15}N$, and $^{13}C$ resonance assignment of a proteolysis-resistant fragment (residues 404-477) in the $HIF1{\alpha}$ ODD domain using NMR spectroscopy. About 98% (344/352) of all the $^1HN$, $^{15}N$, $^{13}C{\alpha}$, $^{13}C{\beta}$, and $^{13}CO$ resonances were unambiguously assigned. The results will be useful for further investigation of the structural and dynamic states of the $HIF1{\alpha}$ ODD domain and its interaction with binding partners.

Currently, the electric fire prediction system uses PIC(Peripheral Interface Controller) for controller microprocessor. PIC has a slower computing speed than DSP does, so its real-time computing ability is inadequate. So with the basic characteristics waveform during arc generation as the standard reference, the comparison to this reference is used to predict and alarm electric fire from arc. While such alarm can be detected and taken care of from a remote central server, that prediction error rate is high and remote control in mobile environment is not available. In this article, the arc detection of time domain and frequency domain and wavelet-based adaptation algorithm executing the adaptation algorithm in conversion domain were applied to develop an electric fire prediction system loaded with new real-time arc detection algorithm using DSP. Also, remote control was made available through iPhone environment-based app development which enabled remote monitoring for arc's electric signal and power quality, and its utility was verified.

Purpose: This study was aimed to modify and adapt the previously developed, high-quality enteral tube feeding guidelines for the usage in clinical settings in Korea. Methods: Guideline adaptation process was undertaken according to the guideline adaptation manual version 2.0 developed by NECA (Kim, et al., 2011) and the standardized methodology for nursing practice guideline adaptation (Gu, et al. 2012). Results: The modified and adapted enteral tube feeding guidelines were consisted of 11 domains and 95 recommendations. The domains and numbers of recommendations in each domain were: 4 on general issues, 2 on enteral nutrition indication and discontinue, 6 on enteral nutrition device selection, 12 on enteral tube feeding device insertions, 3 on enteral nutrition formular and choices, 16 on enteral tube feeding start and progress, 20 on enteral tube feeding maintenance and management, 15 on monitoring enteral tube feeding administration, 10 on prevention of error, 5 on medication administration, and 2 on documentation and report. There were 16.1% of the recommendations marked as A grade, 17.8% of B grade, and 66.1% of C grade. Conclusion: The adapted enteral tube feeding nursing practice guideline is to be added to the evidence-based practice guidelines for fundamentals of nursing practice. The guideline is hoped to be disseminated to nurses nationwide in order to improve the efficiency of enteral tube feeding practice.

Purpose: This study aimed to develop an evidence-based nursing practice guideline for preventing postoperative pulmonary complications (PPCs). Methods: The guideline adaptation process was conducted through the 24 steps based on the guideline adaptation manual of Korean Hospital Nurses Association. Results: The newly developed guideline to prevent PPCs consisted of four domains and 30 recommendations. The number of recommendations in each domain was 7 for assessment of PPCs, 17 for nursing interventions to prevent PPCs after general anesthesia, 4 for education (intended for patients and medical staff), and 2 for monitoring and recording. Conclusion: The developed guidelines will contribute in standardization of nursing practice and PPCs prevention and management. We recommend the dissemination and utilization of these guidelines nationwide to improve the quality of postoperative pulmonary complication prevention.

Generating a project network of a specific construction project is very time consuming and difficult task in the field. To effectiviely automate and support the planning process, we design a case-based project planning expert system inspired by the fact a human expert project planner uses previous cases for planning a new project. A construction project case consist of its specific characteristics and the corresponding project network (i.e. project plan). Using frame based representation. we represent the project features affecting the progress network and the entities composing the project plan such as the buildings, construction methods, WBS (work breakdown structure), activities, and resources. The project planning process runs through most similar case retrieval, case adaptation, and user requirement satisfaction. We represent the construction domain knowledge for each procedure using constraints and rules. We develop the methodology for constraint-based case adaption. Case adaptation process mainly consist of activity generation/deletion and predecence constraint satisfaction, for which we develop the dynamic constraint generation method and connect user-level requirement representation the system-level network modification knowledge. The methodology is being applied to the prototype for apartment construction project planning.

In this paper, we present a new adaptive filter structure which is based on polyphase decomposition of the filter to be adapted. This structure uses wavelet transform to acquire transform-domain coefficients of the input signal. With this coefficients RLS algorithm is used for adaptation. Particularly, using the polyphase parallel structure, we can trace the system which has very long impulse response with only increasing the subband, and show that computational savings can be achieved. The proposed structure was applied to system identification for performance estimation and compared with fullband adaptive filter.
