  • The linear programming model is a special form of useful knowledge that is embedded in a database. Since formulating models from scratch requires knowledge-intensive efforts, knowledge-based formulation support systems have been proposed in the Decision Support Systems area. However, they rely on the assumption that sufficient domain knowledge should already be captured as a specific knowledge representation form. Hence, the purpose of this paper is to propose a methodology that finds useful knowledge on building linear programming models from a database. The methodology consists of two parts. The first part is to find s first-cut model based on a data dictionary. To do so, we applied the General Problem Solver(GPS) algorithm. The second part is to discover a second-cut model by applying neural network technique. An illustrative example is described to show the feasibility of the proposed methodology.

  • Purpose - This study attempts to measure the management performance of a food manufacturer using the BSC as one of the main business management techniques used to achieve the vision of a corporation. Research design, data, methodology - The measurement of business performance of a Japanese food manufacturer was conducted from four perspectives of BSC. Matsui (2005) developed the 'Cross-analysis chart'. Results - First, there were many cases where a minor wastage of raw materials was related to increasing costs. Second, the food manufacturer should try to recover the investment cost through significantly increasing the rate of the facility's operations. Third, reducing personnel expenses could be an important issue in labor-intensive manufacturing. Fourth, customer management was very important in the food manufacturing business. Finally, the food manufacturer should actively consider proposals influencing the food culture to secure high profits in the future. Conclusions - There were many limitations in applying these results to Korean food manufacturers, as this study applied to and analyzed the results in the context of the Japanese food manufacturer.

  • Blackboard provides a collaborative environment for teaching in terms of assessment and communication and can improve learning outcomes. To evaluate the Blackboard use of faculty members at Umm Al-Qura University, data were collected from two channels: statistical reports issued by the university and an online questionnaire. The questionnaire survey respondents were 187 faculty members from all colleges in the university. The findings show that most faculty members did not use Blackboard before the pandemic; therefore, the sudden conversion to the use of Blackboard required intensive training courses. In addition, accompanying Blackboard use with other applications such as WebEx is preferable, especially for administrative tasks such as departmental board meetings and seminars.

  • Intelligent Character Recognition System for Account Payable (ICRS AP) Automation represents the process of capturing text from scanned invoices and extracting the key fields from invoices and storing the captured fields into properly structured document format. ICRS plays a very critical role in invoice data streamlining, we are interested in data like Vendor Name, Purchase Order Number, Due Date, Total Amount, Payee Name, etc. As companies attempt to cut costs and upgrade their processes, accounts payable (A/P) is an example of a paper-intensive procedure. Invoice processing is a possible candidate for digitization. Most of the companies dealing with an enormous number of invoices, these manual invoice matching procedures start to show their limitations. Receiving a paper invoice and matching it to a purchase order (PO) and general ledger (GL) code can be difficult for businesses. Lack of automation leads to more serious company issues such as accruals for financial close, excessive labor costs, and a lack of insight into corporate expenditures. The proposed system offers tighter control on their invoice processing to make a better and more appropriate decision. AP automation solutions provide tighter controls, quicker clearances, smart payments, and real-time access to transactional data, allowing financial managers to make better and wiser decisions for the bottom line of their organizations. An Intelligent Character Recognition System for AP Automation is a process of extricating fields like Vendor Name, Purchase Order Number, Due Date, Total Amount, Payee Name, etc. based on their x-axis and y-axis position coordinates.

  • Purpose: This study was performed to identify the risk factors for oral mucosa pressure ulcer development in intubated patients in adult intensive care unit. Methods: Comparative descriptive study design using prospective observational design and medical record review was used. The inclusion criteria of case was that a) patients of 18 years in their age, b) patients with endotracheal tube. Data of 34 patients were analysed. Descriptive statistics, chi-square test, Fisher's exact test, Mann-whitney test, Spearman's rho correlation coefficients, and multiple logistic regression analysis were used. Resampling methods such as bootstrap was used in this study because of small number of patients. Results: Oral mucosa pressure ulcer developed in 44.1% of the intubated patients. The risk factors of oral mucosa pressure ulcer were steroid use, biteblock use and serum albumin level. Compared to the non-user of steroid, user of steroid had 32.59 times (95% CI: 1.47-722.44) higher risk of developing oral mucosa pressure ulcer. The user of biteblock had 18.78 times (95% CI: 1.00-354.40) and albumin level had 0.03 times (95% CI: 0.00-0.80) higher risk of oral mucosa pressure ulcer incidence. Conclusion: Based on the results of this study, tailored pressure relief strategies considering sex and therapeutic condition should be provided to decrease oral mucosa pressure ulcer.

  • Purpose: The purpose of this study was to examine the effects of a closed endotracheal suction system(CES) on oxygen saturation, ventilator associated pneumonia(VAP), and nursing efficacy in mechanically ventilated patients. Method: This study was conducted in the intensive care unit of a University Hospital in Gwangju City. Data was collected from July to October, 2003. Seventy mechanically ventilated patients were randomly divided into two groups; 32 for CES and 38 for open endotracheal suction system(OES) protocol. Twenty one nurses were also involved to examine the nurses' attitude of usefulness about CES. Result: $SaO_2$ was significantly different between CES and OES. The incidence of VAP in CES was lower than that of OES. Nursing efficacy was related to time, cost, and usefulness of the suction system. Time of suctioning in CES was shorter than that of OES. CES also contributed significantly to lower the cost of treatment than OES. The usefulness score of CES increased after 6 months of use. Conclusion: CES prevented VAP, was cost effective, and a safe suctioning system. CES can be used with patients with sensitivity to hypoxygenation and with a high risk of VAP.

  • Purpose: This study aimed to characterize the relationship between parental stress and nurses' communication as perceived by parents of high-risk newborns in a neonatal intensive care unit (NICU). Methods: The participants were 54 parents of high-risk newborns in a NICU. Data were collected from January to March 2018. Parental stress and parents' perceptions of nurses' communication ability and styles were measured using a questionnaire. Results: The average scores for parental stress and nurses' communication ability were 3.39 and 4.38 respectively, on a 5-point scale. Parents most commonly reported that nurses showed a friendly communication style, followed by informative and authoritative styles. Mothers and fathers reported significantly different levels of parental stress. Parental stress showed a negative correlation with nurses' perceived verbal communication ability. Higher scores for nurses' verbal communication ability and for friendly and informative communication styles were associated with lower parental stress induced by the environment, the baby's appearance and behaviors, and treatments in the NICU. Conclusion: The findings of this study suggest that nurses need to offer proper information for parents and to support parents by encouraging them to express their emotions of stress and by providing parents with therapeutic communication and opportunities to participate in care.

  • The validity of the hypothesis that between-breed differences of carcass composition in cattle can be reduced when compared at the same degree of maturity was assessed using carcass data of various breeds obtained from slaughter experiments in Denmark, Japan and Malaysia. All cattle were kept in intensive feeding conditions in this study. With respect to temperate data (Danish and Japanese data), although large between-breed differences were found in carcass composition in the comparison at the same slaughter weight, the differences were reduced when compared at the same degree of maturity. This result supported the above hypothesis. Kedah-Kelantan and their crosses in Malaysian data, however, had more muscle and bone contents but less fat content than temperate breeds, even if compared at the same degree of maturity. This could be attributed to the history that native Kedah-Kelantan breed has adapted itself in the direction of decreasing fat deposition which requires much energy and prevents heat evaporation, in order to survive under high temperature and high humiodity conditions in Malaysia. In spite of the same tropical breed, carcass composition of Sahiwal-Friesian was similar to that of other temperate breeds at the same degree of maturity.

  • Ventilator-associated pneumonia (VAP) is a lung infection that develops in patients receiving mechanical ventilation. VAP contributes to about 50% of hospital-acquired pneumonia in ICU settings. One of the recommendation of the Institute of for Healthcare Improvement ventilator bundle is HOB elevation. HOB elevation affects shearing forces and makes higher risk for pressure injury development. Pressure injury (PI) is localized damage to the skin over a bony prominence. PI prevention guidelines recommend that HOB positioning should be lower to reduce risk for PI development which contradicts VAP prevention guidelines for the HOB between 30 and 45 degrees for ICU patients. This presents a care dilemma and tension. The purpose of this study was to perform a secondary data analysis using cumulative electronic health record data in order to determine the association of HOB elevation with VAP and PI in ICU patients. A secondary data analysis was conducted to determine whether HOB elevation is associated with VAP and PI. HOB elevation was not likely to be associated with VAP prevention whereas it was likely to be related to PI development. This is somewhat contrary to popular data and publications. Prospective cohort study is desired to inform us in an evidence-based fashion what actually is optimal HOB elevation for ventilated patients in ICU settings.
