Current codes of practice do not exist in isolation, and rules that have been developed assume certain material properties and minimum workmanship in fabrication and erection. These are either in separate documents or different parts of the code. This paper explains the main requirements for materials and workmanship and how they can be related to design and construction in general. The use of very high strength steels is also considered and the measures that may be needed to allow their use with modern codes are also presented.

In this paper, the current problems and challenges of mathematics teachers practice and conditions are discussed with an oriental perspective. What are mathematics teachers' needs of their professional practice? What contradictions and difficulties do they meet in the condition of their professional development? The problems and challenges are described with the result of a group of surveys.

The article reports data on, and numerical modelling of, beams exhibiting points of inflection and subjected to sequential loading. Both tests and analysis point to inadequacies in current codes of practice. An alternative design methodology, which is strongly associated with the notion that contraflexure points should be designed as "internal supports", is shown to produce superior performance even though it requires significantly less secondary reinforcement than that advocated by codes.

Purpose: The purpose of this paper was to discuss the need for translation studies in dementia care and current translational endeavors, and to provide recommendations for evolving evidence-based dementia care. Methods: A literature review yielded current evidence and translational efforts. Results: Dementia care interventions need to be implemented at various service levels. Barriers to translation include evidence gaps, lack of the use of a conceptual framework to explain the implementation process, and unsupportive funding mechanisms for applying innovations. Conclusion: There is clear evidence of the need for and benefits of evidence-based dementia care for patients with dementia, family caregivers, and care professionals. The urgent need now is finding ways to advance translational activities and facilitate future research into translation science.

The particular market situation provision of the WTO Antidumping Agreement is increasingly invoked against what may be described as "input-dumping," but this potentially violates the current Antidumping Agreement rules. This paper examines the practice and recent changes regarding the PMS provision in the US by critically examining relevant antidumping investigations in the US in light of GATT/WTO jurisprudence. Such US practice has not yet been extensively subjected to scholarly examination. The paper finds that the recent legal change in the US widens the scope and applicability of the PMS provision to cover input subsidies, allowing the use of not only surrogate prices but also surrogate costs. Further, the required standard of evidence to find PMS seems to have been diminished in the recent application. A widespread use of the PMS provision in such a deviant way calls for a fundamental review of the current trade remedy rules of the WTO.

To devise better development plan, survey was conducted about current Farmer's irrigation Practice on upland in the Youngsan River Irrigation Project District IV. Major upland crops are garlic and onion in this region. Currently, upland irrigation is conducted using ground water. It is found that irrigation interval is $2{\sim}3$ day for dry-field rice and $3{\sim}7$ days for other crop, in general. Whole day is required to irrigate for many farmers due to lack of facilities and water source. Farmers have no intention to change staple crops even after completion of Irrigation Project of Youngsan River District IV.

Pepper has been the second important income source of Korean farmer. Provided the agricultural market in Korea is opened, pepper of which price is more than three times of the world market price can not survive with current cultivation practice. Pepper harvesters have been developed in some countries but, they are not feasible in Korea due to difference of varieties, cultivation practice and climate between Korea and other countries. This is a fundamental study to develop a pepper harvester suitable to the current situation in Korea. Physical properties of a pepper plant and its fruit were investigated. Also, a pair of open helices was selected as a pepper removing mechanism and tested to determine the best operating conditions. This study revealed that a pepper harvester with more than 90% of pepper recovery is attainable. Best rotating speed of open helices with 30cm diameter and conveying velocity of pepper main stem were determined to be 180 rpm and 0.1 m/s respectively.

As mega-sized and complex building construction projects are increased, the importance of project scheduling and control is emphasized. Project scheduling and control technic is not used widely yet in Korea, but interests in it is progressively increased. By now, most research projects mainly have focused on scheduling issues. Project progress management is also as much important as project scheduling issues. Current state about project progress management in Korea is analysed and way for improvements are suggested in this paper. At first, research projects undergone and practice are analysed and fields experts are survey about current state about project progress management. This study suggests the progress management method for quantitative and qualitative project progress analysis.

Although mammography is the primary imaging modality for the breast, it has its limitations especially with dense breast parenchyma. Breast magnetic resonance imaging (MRI) has evolved into an important adjunctive tool as it is currently the most sensitive technique for breast cancer detection. Despite this high sensitivity, overlap in the appearances of some benign and malignant breast lesions results in additional unnecessary intervention with negative results. These false positives, in addition to high cost and limited availability, necessitate establishing proper indications for breast MRI. The literature was here reviewed for recent clinical trials, meta-analyses and review papers which have studied this important subject. PubMed; the US national library of medicine, was utilized to review the literature in the last twenty years. Using the obtained information, current uses of breast MRI are discussed in this paper to determine the indications which are relevant to clinical practice.

Active application of auger-drilled piling is expected in Korea considering its advantage in noise and vibration problems against driven piling and its cost-effectiveness in comparison to the cast in-situ piling. The current design practice being used in Korea is adopted from the Japanese one, however the equipment and construction procedure is modified for the geotechnical conditions and construction circumstances in Korea. Therefore there is an urgent need for the establishment of the rational design criteria for the auger-drilled piling in Korea. As the preliminary work for the establishment, this paper presents the current practice in Korean railway constructions. Design criteria of Korea Railway Network Authority are introduced and its characteristics and the problems are described. Application cases of auger-drilled pile to railway construction are introduced as well.
