This study analyzes the U.S. case law which challenges the legal conclusions of the district court with respect to the applicability, and effect, of the doctrine of waiver and estoppel in addition to the doctrine of documentary cure. The impliations are as follows. First, the documentary cure requirement can not be interpreted to mean early enough to allow the beneficiary to cure and represent the documents before the presentment deadline or expiry date of letter of credit. The mere fact that the presentment period expired before the completion of bank's review and notification process does not compel any conclusion about whether the examiner spent a reasonable amount of time examining the documents. Indeed, the reasonable time requirement does not imply that banks examine a presentation out of order or hurry a decision based upon particular needs or desires of a beneficiary. Secondly, even if the doctrine of waiver can apply to letter of credit governed by the strict compliance standard, a one-time acceptance of discrepant documents by a bank does not waive the bank's right to insist upon conforming documents in all subsequent letter of credit transactions between the bank and beneficiary. Revised UCC Article 5 is highly persuasive on this point: waiver of discrepancies by issuer or an applicant in one or more presentation does not waive similar discrepancies in a future presentation. Neither the issuer nor the beneficiary can reasonably rely upon honor over past waivers as a basis for concluding that a future defective presentation will justify honor.

The random-based cleaning algorithm is a simple algorithm widely used in commercial vacuum cleaning robots. This algorithm has two limitations, that is, cleaning takes a long time and there is no guarantee that the cleaning will cover the whole cleaning area. This has lead to customer dissatisfaction. Thus, in recent years, many intelligent cleaning algorithms that takes into consideration information gathered from the cleaning area environment have been proposed. The plowing-based algorithm, which is the most efficient algorithm known to date when there are no obstacles in the cleaning area, has a deficiency that when obstacle prevail, its performance is not guaranteed. In this paper, we propose the Group-k algorithm that is efficient for that situation, that is, when obstacle prevail. The goal is not to complete the cleaning as soon as possible, but to clean the majority of the cleaning area as fast as possible. The motivation behind this is that areas close to obstacles are usually difficult for robots to handle, and hence, many require human assistance anyway In our approach, obstacles are grouped by the complexity of the obstacles, which we refer to as 'complex rank', and then decide the cleaning route based on this complex rank. Results from our simulation-based experiments show that although the cleaning completion time takes longer than the plowing-based algorithm, the Group-k algorithm cleans the majority of the cleaning area faster than the plowing algorithm.

In this paper, in order to increase the production efficiency of the industrial plant, and predicts the resources of the manufacturing process, we have proposed a decision-making system for resource implementing the risk management effectively forecasting and risk management. A variety of information that occurs at each step efficiently difficult the creation of detailed process steps in the scenario you want to manage, is a frequent condition change of manufacturing facilities for the production of various products even within the same process. The data that is not contiguous products production cycle also not constant occurs, there is a problem that needs to check the variation in the small amount of data. In order to solve these problems, data centralized manufacturing processes, process resource prediction, risk prediction, through a process current status monitoring, must allow action immediately when a problem occurs. In this paper, the range of change in the design drawing, resource prediction, a process completion date using a regression algorithm to derive the formula, classification tree technique was proposed decision system in three stages through the boundary value analysis.

A field based non-destructive hardness method is being developed to determine plastic strain in steel elements subjected to seismic loading. The focus of this study is on the active links of eccentrically braced frames (EBFs). The 2010/2011 Christchurch earthquake series, especially the very intense February 22 shaking, which was the first earthquake worldwide to push complete EBF systems into their inelastic state, generating a moderate to high level of plastic strain in EBF active links for a range of buildings from 3 to 23 storeys in height. Plastic deformation was confined to the active links. This raised two important questions: what was the extent of plastic deformation and what effect does that have on post-earthquake steel properties? A non-destructive hardness test method is being used to determine a relationship between hardness and plastic strain in active link beams. Active links from the earthquake affected, 23-storey Pacific Tower building in Christchurch are being analysed in the field and laboratory. Test results to date show clear evidence that this method is able to give a good relationship between plastic strain and demand. This paper presents significant findings from this project to investigate the relationship between hardness and plastic strain that warrant publication prior to the completion of the project. Principal of these is the discovery that hot rolled steel beams carry manufacturing induced plastic strains, in regions of the webs, of up to 5%.

As the recent construction projects have been carried out as a mixed-use complex project that includes architecture, civil, mechanical, electrical, and landscape, as well as become bigger and high-rise with the increased repetitive works, the TACT technique has received more attention as an effective method for achieving a target completion date by securing the continuous works. Although the TACT technique can maintain a steady flow without the interruption of works in order to utilize the resources of the repetitive works, it can not be considered as the systematic scheduling technique because the schedule computations are not possible as well as a critical path can not be recognized. This paper proposes the applicabilities of scheduling and monitoring the TACT schedule by the BDM technique as comparing and analyzing the methodologies for apartment finish works by the Excel, the Primavera(P6) based on the PDM technique, and the Beeliner based on the BDM technique that is a new networking technique, respectively.

A major obstacles to evaluation of newly-developed treatment strategy for human lung cancer has been the lack of appropriate experimental animal models. We describe a new experimental model of orthotopically-developed non-small cell lung cancer in nude rat, involving inoculation of tumor cell suspension by thoracotomy. Over 40 direct implantation to the periphery of the lung has been performed to date, each requiring less than'1 hour for completion. This model has been used to perform a series of experiments to investigate whether the rat lung and surrounding structures trapped tumor cells with 2 different non-small cell lung cancer cell lines(NCI-H46O and NCI-H1299). Every animal showed development of tumor masses, which were loculated at the periphery of the lung karenchyma and identified also by radiography. After 3 weetu of the inoculation, tumor develop meat at the mediastinal strutures were identified. The life expectancies of the victims were different between the cell lines, but were approximately 5 weeks when NCI-H46O cell line was used. This new orthotopic lung cancer model may be facilitate future studies of the new therapeutics of localized non-small cell lung cancer .

Background and objective: It is difficult to conclusively determine the exact cause of tree defects since multiple causes are involved such as climate change, plantation, tree quality and planting time, construction, planting base, drainage, sunshine conditions, maintenance, and microclimate. The data related to landscaping construction defects are scattered or fragmented by companies and years, but not managed systematically by the defect information management system. Most of the earlier studies associated with tree defects in apartment complexes suggested defect rates after examining tree defects in the completed construction site and proposed fragmentary and subjective conclusions about the causes of defects observed in trees with high defect rates. It is proposed to continue to conduct studies on the establishment and analysis of systematic databases to identify the exact causes of tree defects and measures to improve, and the need to accumulate systematic data in the construction process where many defects arises. This study was conducted to reduce the defects of trees planted in apartment complexes. Methods: Main factors related to tree defects were subdivided based on the results of literature review and a defect investigation at the completion site, and tree history management items were selected and subdivided during the construction stage. Results: The criteria for the preparation of subdivided items were obtained, and the tree history management checklist was written for the site under actual construction and a systematic database was established. Items that are categorized based to the causes of defects include the location of nurseries, date, tree quality, site conditions, planting techniques, microclimates, and maintenance. Conclusion: This study suggested tree history management items based on the tree defects that can be identified at the construction stage and applied them to the selected study site, which differentiates this study from earlier studies. It will be necessary to conduct a comprehensive and objective time series analysis on tree defects that occur over time by continuously monitoring and collecting data after construction.

The United States (US) National Science Foundation's (NSF's) National Ecological Observatory Network (NEON) is a continental-scale observation facility, constructed and operated by Battelle, that collects long-term ecological data to better understand and forecast how US ecosystems are changing. All data and samples are collected using standardized methods at 81 field sites across the US and are freely and openly available through the NEON data portal, application programming interface (API), and the NEON Biorepository. NSF led a decade-long design process with the research community, including numerous workshops to inform the key features of NEON, culminating in a formal final design review with an expert panel in 2009. The NEON construction phase began in 2012 and was completed in May 2019, when the observatory began the full operations phase. Full operations are defined as all 81 NEON sites completely built and fully operational, with data being collected using instrumented and observational methods. The intent of the NSF is for NEON operations to continue over a 30-year period. Each challenge encountered, problem solved, and risk realized on NEON offers up lessons learned for constructing and operating distributed ecological data collection infrastructure and data networks. NEON's construction phase included offices, labs, towers, aquatic instrumentation, terrestrial sampling plots, permits, development and testing of the instrumentation and associated cyberinfrastructure, and the development of community-supported collection plans. Although colocation of some sites with existing research sites and use of mostly "off the shelf" instrumentation was part of the design, successful completion of the construction phase required the development of new technologies and software for collecting and processing the hundreds of samples and 5.6 billion data records a day produced across NEON. Continued operation of NEON involves reexamining the decisions made in the past and using the input of the scientific community to evolve, upgrade, and improve data collection and resiliency at the field sites. Successes to date include improvements in flexibility and resilience for aquatic infrastructure designs, improved engagement with the scientific community that uses NEON data, and enhanced methods to deal with obsolescence of the instrumentation and infrastructure across the observatory.

Liver transplantation is definitive treatment for the patients suffering from hepatitis, severe liver cirrhosis and liver cancer. In these patients, systemic infections under immunosuppression may occur easily. Therefore, primary object of dental treatments before liver transplantation is absolute removal of oral infection source. In addition, comprehensive dental management plan is essential for success of liver transplantation. The present study has been performed to investigate decayed, missing and filled permanent teeth index(DMFT index), degree of oral hygiene, past medical history, need of dental treatment, completion of dental treatment need and time interval between dental visit and operation date of liver transplantation in liver transplant candidates. Obtained results were as follows; 1. Decayed teeth of the patients were 2.68, missing teeth were 4.02 and filled teeth were 3.42. DMFT index was 10.12. 2. Twenty percents of patients showed moderate to severe food impactions, 42.2% of patients had moderate to heavy calculus and 37.8% of patients displayed gingival inflammation with swelling. 3. Patients needed periodontal treatments more than any other dental treatments. Periodontal treatments were needed for 88.9% of patients, operative & endodontic treatments were 46.7% of patients and 33.3% of patients needed for oral & maxillofacial surgical treatments. 4. Among 90 patients, time interval between scheduled operation date of liver transplantation and dental visit was within 2 weeks for 32.2% of patients, within 1 week for 20.0% of patients. In conclusion, most liver transplant candidates needed dental treatments for removal of potential infection sources. However because of insufficient interval between dental visit and operation date, they had taken liver transplantation procedures without comprehensive dental management. Development of preventive and comprehensive dental management program is mandatory for these patients. Cooperative interdisciplinary management will play a positive role for successful liver transplantation.

The cloning of canids was succeeded in 2005, several years after the birth of Dolly the sheep and also after the cloning of numerous other laboratory and farm animal species. The delay of successful somatic cell nuclear transfer (SCNT)was due to the unique reproductive characteristics of the female dogin comparison to other domestic mammals, such as ovulation of immature canine oocyte and a requirement of 25 days for the completion of meiosis within the oviduct (Holst & Phemister, 1971). When the technology for the recovery of in vivo matured oocyte was established, the application of cloning also became possible and cloned dog offspring were obtained. This report summarizes the progress of technical procedures that are required for cloning canids and the application of this technique. The first cloned dog, Snuppy, was achieved using an in vivo-matured oocyte which was enucleated and transferred with an adult skin cell of male Afghan hound. After establishment of a criterion of well-matured oocyte for the improvement of SCNT efficiency, we obtained three cloned female Afghan hound and a toy poodle cloned from 14 year-old aged Poodle using SCNT through this factor. To date, cloned dogs appeared to be normal and those that have reached puberty have been confirmed to be fertile. Through application of canine SCNT technique, first, we demonstrated that SNCT is useful for conserving the breed of endangered animal from extinction through cloning of endangered gray wolves using inter-species SCNT and keeping the pure pedigree through the cloning of Sapsaree, a Korean natural monument. Secondly, we showed possibility of human disease model cloned dog and transgenic cloned dog production through cloning of red fluorescent protein expressing dog. Finally, SCNT can be used for the propagation of valuable genotypes for making elite seed stock and pet dog. In summary, dog cloning is a reproducible technique that offers the opportunity to preserve valuable genetics and a potential step towards the production of gene targeted transgenic cloned dogs for the study of human diseases.
