The purpose of this study was an analysis of the elementary school child's attitude and dangerous factors of play apparatuses n elementary schools. The results were summarized as follows; 1. 53.0% of the reply child thought that play apparatuses were dangerous, and 41.0% of the total reply had experienced accidents by apparatuses, the child under 10 had experienced the accidents manytimes. 2. The types of injuries most frequently occurred are falls from play apparatuses, and part of the body most frequently injured parts of the body are arms and legs. 3. The danger of fall in play apparatuses that is over 3M amounted 19.6%, it asked safety of bottom materials. 4. Destructed play apparatuses reached up to 20.0%, and rusted or decomposed apparatuses reached to 28.4%. 5. The distance of each apparatus were very close ; it was within 0.3~1.5M, which was 24.9%, it was very dangerous factor. 6. The most frequent hazards of educational play apparatuses are ; - inappropriate size of apparatuses(height, gap, thick etc.)- inappropriate shape and finished state(bad welding and cutting, projection part etc.)- unsuitable use of bottom material in playground and safety color.- insufficient use zone.-inappropriate maintenance and inspection(endurance passage, erosin of iron-ware and wooden ware, projection of foundation concrete)

Continuous industrial development has led to a better quality of life for everyone, even further accelerating industrial growth. Industrial development, however, has also caused environmental degradation, which is posing a serious threat to humanity. It has also encouraged the indiscriminate use of limited resources, causing resource depletion. Efficient resource management based on resource circulation is critical to saving resources. Resource circulation methods are as follows: reducing the use of resources in the manufacturing process, recycling used or reprocessed products and reusing used resources without being reprocessed, remanufacturing with end-of-life products with disassembled parts. Furthermore, remanufacturing process including cleaning, inspection, repairing, and reassembling facilitate performance level as well as new typical products. It is noteworthy that the remanufacturing of machine tools can significantly save resources because their structural parts are substantially large in size. Machine tools have served as a foundation for the manufacturing industry, which has driven Korea's industrial development. Nevertheless, a few research has been reported for remanufacturing technology with used machine tools. Relevant research of developing a remanufacturing process chart and method is prerequisite for saving the resource and environments.

It is one of the most important factors Seafarers Ducation Quality Assurance and Management in Higher Maritime Educational Institution. The educational process and result of Higher Maritime Educational Institution should be evaluated according to the 1995 Amendments to the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers(STCW), 1978. Actually above-mentioned evaluation is deemed to make foundation in order to enhance the efficiency of shipboard education by surveying the satisfaction of shipboard training for nautical part cadets by the group. In this paper, we carried out the questionnaire survey to study satisfactory value and the reason of dissatisfaction of 113 cadets being trained on board the Training Ship in Maritime College of Korea Maritime University(K. M. U.). The results were calculated by frequency and percentage ; the significance of difference among Department groups like Maritime Transportation Science, Maritime Police and Ship Operating Systems Engineering was analysed by $X^2$ inspection. The major results of above analysis were as follows : First training chance for dadets was very little for being overflowed on board the training ship of the K. M. U. Second, special type of Training Ship HANBADA and HANNARA made the adaptability to merchant vessel's handling restricted. Third, cadets could not manage ratings directly, therefore the education in regard to seafaring management was limited to the theoretical instruction which leads to the low level of satisfaction. And lastly, low value of satisfaction for Drydocking Education in Shipyard was caused by cadet's leaving the Training Ship on account of the safety problems including ship and cadets.

This study is aimed to apply basic data to planning earth building through analyzing characteristics of earth building. For doing it, we investigated a research paper in advanced countries(New zealand, Australia, etc.) that has been used for earth building standards for a long time, and then we corrected inadequate standards that would apply our earth building environment. As a result, we can devide earth characteristics into three parts that are materials, plan, and maintenance and repair. First, as material selection is very important factor, a general plan is possible to change in accordance with what material is selected. These methods that made mud brick, pressed earth block, rammed earth, cob have been well used during the current 30 years in earth building. Second, the plan is composed of site select and architecture plan. In architecture plan, we should consider from foundation to eaves protection, and in site selection, consider sides of the environment and the social. Third, we should always check a periodical inspection through watchful observation because earth buildings need more time and efforts in maintaining and repairing than others.

In-place analysis for offshore platforms is essentially required to make proper design for new structures and true assessment for existing structures. The structural integrity of platform components under the maximum and minimum operating loads of environmental conditions is required for risk assessment and inspection plan development. In-place analyses have been executed to check that the structural member with all appurtenances robustness and capability to support the applied loads in either storm condition or operating condition. A nonlinear finite element analysis is adopted for the platform structure above the seabed and the pile-soil interaction to estimate the in-place behavior of a typical fixed offshore platform. The analysis includes interpretation of dynamic design parameters based on the available site-specific data, together with foundation design recommendations for in-place loading conditions. The SACS software is utilized to calculate the natural frequencies of the model and to obtain the response of platform joints according to in-place analysis then the stresses at selected members, as well as their nodal displacements. The directions of environmental loads and water depth variations have important effects on the results of the in-place analysis behavior. The result shows that the in-place analysis is quite crucial for safe design and operation of offshore platform and assessment for existing offshore structures.

The 750 m long "De Bosset" bridge in the Cephalonia Island of Western Greece, being the area with the highest seismicity in Europe, was constructed in 1830 by successive stone arches and stiff block-type piers. The bridge suffered extensive damages during past earthquakes, such as the strong M7.2 earthquake of 1953, followed by poorly-designed reconstruction schemes with reinforced concrete. In 2005, a multidisciplinary project for the seismic assessment and restoration of the "De Bosset" bridge was undertaken under the auspices of the Greek Ministry of Culture. The proposed retrofitting scheme combining soil improvement, structural strengthening and reconstruction of the deteriorated masonry sections was recently applied on site. Design of the rehabilitation measures and assessment of the pre- and post-interventions seismic response of the bridge were based on detailed in-situ and laboratory tests, providing foundation soil and structural material properties. In-situ inspection of the rehabilitated bridge following the strong M6.1 and M6.0 Cephalonia earthquakes of January 26th and February 3rd 2014, respectively, revealed no damages or visible defects. The efficiency of the bridge retrofitting is also proved by a preliminary performance analysis of the bridge under the recorded ground motion induced by the above earthquakes.
