Passenger safety is a primary concern of the railway system. However, dozens of people are killed every year when they accidently fall on to the track from the boarding platform. This is one of the most urgent issues to solve regarding the railway platform. The installation environment, and the blind area problems as well as maintenance and operating costs which are not efficient have to be looked at. To solve these problems, we propose a 3D laser radar sensor based monitoring system for the railway platform. This paper introduces an overview, the detecting method, and the interface with the signalling system in detecting a fallen passenger from the platform using the 3D laser radar sensor.

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.

Current trends in the Korean construction industry, including the aging of the workforce, a lack of new Korean construction workers, and an inflow of unskilled foreign labor, have caused a range of problems, including quality deterioration, reduced productivity, insufficient understanding of the function and difficulties in communication, to name a few. Yet while countermeasures to these problems should be based on accurate and diverse fundamental data, including the current status of demand and supply of domestic and foreign construction workers, the perception of construction workers, studies on these questions have, thus far, been scarce. For these reasons, this study was conducted using a questionnaire for managers and workers on construction sites, to secure fundamental data relating to construction workers. The findings of the survey showed that it is urgent to prepare measures to educate, train and foster human resources, considering the aging of the construction workforce and the lack of an inflow of new construction workers.

Free-form buildings refer to geometric external structures in curved form, unlike conventional structures with straight lines. The development of construction technologies for the implementation of these Free-form buildings is ongoing. However, there are still many restrictions on the construction technology of Free-form buildings, resulting in problems such as increased construction period and increased construction costs. Therefore, it is urgent to develop building technology for the construction of Free-form building in order to secure competitiveness in the global Free-form building market. Accordingly, this study proposes Two-sided multi-point press technology that can solve problems of existing technology and implement FCP(Free-form Concrete Panel).

Due to the aging of economically active population in the world, the average age of workers in the domestic construction industry is also steadily increasing. This study analyzes the aging of construction workers in small-size construction sites in Busan, where the aging of the economically active population is the most severe in Korea. As a result of the study on the aging of construction workers in six construction sites with a construction cost of less than 500 million won in Busan, it was found that 65% of the workers were over 50 years of age. In addition, several experts interviews and survey revealed that 'securing welfare facilities for construction workers' and 'diminishing prejudice about the construction industry" were the most urgent and effective methods to overcome the aging problems. The results of this study can be served as basic data to solve the aging problems in the industry.

Roughly one third of medical problems in children are related to the musculoskeletal system. Most of these problems are common and can be precisely diagnosed. For these problems, nonoperative treatment or reassurance can be given by the pediatrician. Occasionally, a problem needs surgical treatment, but a precise diagnosis must be made. There is little agreement about what types of orthopedic problems a primary care pediatrician should understand in order to effectively care for children. Many pediatric residencies lack an organized teaching curriculum that effectively covers these topics or that includes a required pediatric orthopedic rotation. In this article the authors delineate pediatric orthopedic problems that require recognition and urgent surgical treatment and are relatively common, but have different treatment options (observation, conservative treatment, and surgery) depending on their natural history. Whenever possible, the diagnosis should be made before a decision to refer is made. An accurate diagnosis allows the pediatrician to discuss the natural history of the condition properly. Referral to the wrong specialty can needlessly generate expensive tests and further delay in treatment or generate inappropriate treatment. The parents can be reassured rather than waiting to hear the same information from another physician. In particular, orthopedic problems are known to generate pressure from the parents to seek specialty consultation for reassurance. It is important to communicate to the specialist that the reason for the referral is for parental reassurance rather than for further work-up or treatment. After a proper diagnosis, communication directly between the pediatrician and the appropriate specialist can often avoid an unnecessary referral, and avoid unnecessary tests. The authors reviewed our experience at our outpatient clinic over last 1 year and found that it is useful to classify conditions as common or uncommon, and whether they require surgical or nonsurgical treatment. Many conditions fall in between. The following is a discussion of some of these more important or common conditions.

Over the last century, medical education in North America has evolved by identifying educational challenges within its own socio-cultural context and by appropriately responding to these challenges. A discipline-based curriculum, organ-system or integrated curriculum, problem-based curriculum, and competency-based curriculum are historical examples of the educational solutions that have been developed and refined to address specific educational challenges, such as students' lack of basic scientific knowledge, lack of integration between scientific knowledge and clinical practice, and lack of clinical practice. In contrast, Korean medical education has evolved with the influence of two forces: (1) the adoption of educational solutions developed in North America by pioneers who have identified urgent needs for medical education reform in Korea over the last three decades, and (2) the revitalization of Korean medical schools' curricula through medical education accreditation and national medical licensing examination. Despite this progressive evolution in Korean medical education, we contend that it faces two major challenges in order to advance to the next level. First, Korean medical education should identify its own problems in medical education and iteratively develop educational solutions within its own socio-cultural context. Secondly, to raise reflective doctors who have scientific knowledge and professional commitment to deal with different types of medical problems within a continuum from well-defined to ill-defined, medical education should develop innovative ways to provide students with a balanced spectrum of clinical problems, including uncertain, ill-defined problems.

This study analyzed and mutually compared the fishery manpower problems in Northeast Asia region including Korea, China, Japan by fishery industry structure, fishery education, fishery manpower and presented fishery cooperative schemes of Northeast Asia. In case of fishery manpower problems, China is still in a better situation whereas Korea and Japan have a hard time of a labor shortage. Korean companies have employed foreign crews to find a way out of the difficulties and the foreign crew rate is growing but the problem is that the reduction of Korean crew could deteriorate the safety of vessel-sailing, efficient operations, and fishery efficiency. Therefore crew management should be placed focus on improvement of working conditions and guarantee positions to foreign crew as assistants in fishery surroundings and systems. Fishery manpower problems are complementary to each nation in Northeast Asia. In consideration of this fact, fishery manpower management needs the mutual fishery manpower and information exchange and for the sake of it, the most urgent task is to build up the international fishery cooperative network through establishing fishery-related information systems of Northeast Asia.
