  • Patients with terminal cancer experience very severe symptoms during the end of life, and palliative sedation (PS) may be considered if those symptoms are refractory to any other treatment. This brief report presents ethical considerations, practices, and recent concerns on PS. PS is quite different from euthanasia. There is a lack of consensus and standards on protocols, but its notable effects have been reported in hospice care settings. Most studies to date have reported no difference in survival between patients receiving PS and those not, and PS must be conducted proportionally with the lightest level of sedation. The most common indication for PS is delirium, and midazolam is the main sedative used. It is recommended that information regarding PS should be provided to patients and their caregivers repeatedly as early as possible. Existential suffering alone is not an indication for PS, and there is a lack of evidence on bispectral analysis. Additional research on PS is needed in Korea.

  • Objective: A national survey was conducted to assess orthodontic residents' current concepts and knowledge of cleft lip and palate (CLP) management in Korea. Methods: A questionnaire consisting of 7 categories and 36 question items was distributed to 16 senior chief residents of orthodontic department at 11 dental university hospitals and 5 medical university hospitals in Korea. All respondents completed the questionnaires and returned them. Results: All of the respondents reported that they belonged to an interdisciplinary team. Nineteen percent indicated that they use presurgical infant orthopedic (PSIO) appliances. The percentage of respondents who reported they were 'unsure' about the methods about for cleft repair operation method was relatively high. Eighty-six percent reported that the orthodontic treatment was started at the deciduous or mixed dentition. Various answers were given regarding the amount of maxillary expansion for alveolar bone graft and the estimates of spontaneous or forced eruption of the upper canine. Sixty-seven percent reported use of a rapid maxillary expansion appliance as an anchorage device for maxillary protraction with a facemask. There was consensus among respondents regarding daily wearing time, duration of treatment, and amount of orthopedic force. Various estimates were given for the relapse percentage after maxillary advancement distraction osteogenesis (MADO). Most respondents did not have sufficient experience with MADO. Conclusions: These findings suggest that education about the concepts and methods of PSIO and surgical repair, consensus regarding orthodontic management protocols, and additional MADO experience are needed in order to improve the quality of CLP management in Korean orthodontic residents.

  • Purpose : To conduct nationwide surgery on the principles In radiotherapy for rectal center, and develop the framework of a database of Korean Patterns of Care Study. Materials and Methods : A consensus committee was established to develop a tool for measuring the Patterns in radiotherapy Protocols for rectal cancer. The Panel was composed of radiation oncologists from 18 hospitals in Seoul Wetropolltan area. The committee developed a survey format to analyze radiation oncologist's treatment principles for rectal cancer. The survey items developed for measuring the treatment principles were composed of 1) 8 eliglblllty criteria, 2) 20 Items for staging work-ups and prognostic factors, 3) 7 Items for principles of combined surgery and chemotherapy, 4) 9 patient set-ups, 5) 19 determining radiation fields, 6) S radiotherapy treatment pians, 7) 4 physicalilaboratory examination to monitor a patient's condition during treatment, and 8) 10 follow-up evaluations. These items were sent to radiation oncoioglsts In charge of gastrolntestlnal malignancies in all hospitals (48 hospitals) In Korea to which 30 replies were received (63$\%$). Results : Most of the surrey Items were replied to without no major between the repliers, but with the fellowing items only 50$\%$ of repliers were in agreement : 1) Indications of preoperative radiation, 2) use of endorectal ultrasound, CT scan, and bone scan for staging work-ups, 3) principles of combining chemotherapy with radiotherapy, 4) use of contrast material for small bowel delineation during simulation, 5) determination of field margins, and 6) use of CEA and colonoscopy for follow-up evaluations. Conclusions : The Items where considerable disaggrement was shown among the radiation oncologists seemed to make no serious difference In the treatment outcome, but a practical and reasonable consensus should be reached by the committee, with logical processes of agreement. These Items can be used for a basic database for the Patterns of Care Study, which will survey the practical radiotherapy Patterns for rectal cancer in Korea.

  • In Korea, implementation of nutrition support guidelines has been limited due to strict health insurance reimbursement policies as well as the lack of consensus on the best approach to TPN management. We examined the impact of TPN provision to hospitalized patients where NST (nutrition support team ) consultations were not requested by their primary physicians. The study showed the followings : 1. The median dutation of TPN provision was 8 days, but many patients were on TPN for less than 1 week. 2. The intake of energy and protein were less than the patient's requirements 3. Lipid emulsion was not provided to the most TPN patients. In conclusion, the role of NST should be expanded and studies are needed not only on TPN formulations which are suitable to Koreans but also on the cost-effectiveness of NST activities. TPN policies and protocols should be established based on the needs of each hospital.

  • Biological data and analysis tools are accumulated in distributed databases and web servers. For this reason, biologists who want to find information from the web should be aware of the various kinds of resources where it is located and how it is retrieved. Integrating the data from heterogeneous biological resources will enable biologists to discover new knowledge across the specific domain boundaries from sequences to expression, structure, and pathway. And inevitably biological databases contain noisy data. Therefore, consensus among databases will confirm the reliability of its contents. We have developed WeSAT that integrates distributed and heterogeneous biological databases and analysis tools, providing through Web Services protocols. In WeSAT, biologists are retrieved specific entries in SWISS-PROT/EMBL, PDB, and KEGG, which have annotated information about sequence, structure, and pathway. And further analysis is carried by integrated services for example homology search and multiple alignments. WeSAT makes it possible to retrieve real time updated data and analysis from the scattered databases in a single platform through Web Services.

  • Wind uplift rating of roofing systems is based on standardized test methods. Roof specimens are placed in an apparatus with a specified table size (length and width) then subjected to the required wind load cycle. Currently, there is no consensus on the table size to be used by these testing protocols in spite of the fact that the table size plays a significant role in wind uplift performance. Part I of this paper presented a study with the objective to investigate the impact of table size on the performance of roofing systems. To achieve this purpose, extensive numerical experiments using the finite element method have been conducted and benchmarked with results obtained from the experimental work. The present contribution is a continuation of the previous research and can be divided into two parts: (1) Undertake additional numerical simulations for wider membranes that were not addressed in the previous works. Due to the advancement in membrane technology, wider membranes are now available in the market and are used in commercial roofing practice as it reduces installation cost and (2) Formulate a logical step to combine and generalize over 400 numerical tests and experiments on various roofing configurations and develop correction factors such that it can be of practical use to determine the wind uplift resistance of roofs.

  • Wind uplift rating of roofing systems is based on standardised test methods. Roof specimens are placed in an apparatus with specified table size (length and width) then subjected to the required wind load cycle. Currently, there is no consensus on the table size to be used by these testing protocols in spite of the fact that a table size plays a significant role in evaluating the performance. This paper presents a study with the objective to investigate the impact of table size on the performance of roofing systems. To achieve this purpose, extensive numerical experiments using the finite element method have been conducted to investigate the performance of roofing systems subjected to wind uplift pressures. Numerical results were compared with results obtained from experimental work to benchmark the numerical modeling. Required table size and curves for the determinations of appropriate correction factors are suggested. This has been completed for various test configurations with thermoplastic waterproofing membranes. Development of correction factors for assemblies with thermoset and modified bituminous membranes are in progress. Generalization of the correction factors and its usage for wind uplift rating of roofs will be the focus of a future paper.

  • Although total ankle arthroplasty (TAA) has increased considerably in the past ten years, reflecting improvements in implant design and survivorship, the clinical outcomes have been less satisfactory than total hip or total knee arthroplasties. Several issues under debate include postoperative management and rehabilitation in TAA. Especially, there is no consensus or evidence for the most appropriate postoperative management and rehabilitation for patients undergoing TAA. This study was therefore undertaken to suggest appropriate postoperative management and rehabilitation in TAA, after reviewing published articles and focusing on the following topics: prehabilitation, hospital stay, immobilization type and duration, weight-bearing management, pharmacological treatment, and adopted rehabilitation protocols. In previous studies, the postoperative management and rehabilitation proposed depended on the surgeon's preference, the patient's characteristics, and the associated surgical procedures performed after TAA. Nonetheless, our research indicates the best approach is to include a prehabilitation program, immobilization in the early postoperative stage (2~4 weeks), range of motion exercise with partial weight-bearing ambulation, followed by full weight-bearing ambulation after six weeks. Further studies are required to develop a standardized rehabilitation protocol and improve the overall quality of care after TAA.

  • Building Information Modeling, and its associated work practices, requires project participants to share not only 3D geometric data, but also information in the model that may be considered proprietary and even trade secrets. Thus protection of intellectual property, or BIM copyrights, must be in place for participants to share proprietary information among project stakeholders. Currently Korea does not have adequate copyright laws or mechanisms to provide such protection. This research examined three BIM copyright legal documents, namely U.S.' ConsensusDOCS 301, AIA Document E203/G202, and U.K.'s CIC BIM Protocol to determine how copyright protection is realized, and to formulate appropriate stipulations within the Korean construction context. The resultant requirements include stipulating ownership at to the BIM originator, adopting a license-sublicense scheme, employing a federated model, and use of a formal model delivey table to allocate responsibilities. Given Korea's adoption stage, liability should be minimal, and license revocation should be allowed if payments are not met. The three BIM legal documents focus on practical measures that allow participants to customize requirements for individual projects, and such conventions should be emulated in Korea.

  • BACKGROUND: Consensus of heavy metal phytoavailability in soils needs to be introduced for soil management protocols in relation to safer food production in the contaminated agricultural soils. For this, setting up the method for evaluation of metal phytoavailability in soil is an essential prerequisite. METHODS AND RESULTS: The current study was carried to select a proper single extraction method for determination of phytoavailable metal concentration in soil. Two extraction methods were examined including 1 M $NH_4NO_3$ extraction and 0.01 M $Ca(NO_3)_2$ extraction methods using 142 soil samples collected from the agricultural soils nearby abandoned mining area in Korea. Corelation analysis was conducted between phytoavailable metal concentrations and soil properties potentially influencing on the metal phytoavailability. Both methods showed similar significance (p<0.001) in correlation with soil properties such as soil pH. However, higher correlation coefficients between phytoavailable metal concentrations and soil properties were observed when used $Ca(NO_3)_2$ extraction rather than using $NH_4NO_3$ extraction. CONCLUSION(S): It appeared that 0.01 M $Ca(NO_3)_2$ extraction was better option for determination of phytoavailable metals in soils and further study to test the efficiency of this method is required in combination with plant uptake.
