  • This study was aimed at examine eating behavior and food preferences of children in preschool nursery facilities. A survey was conducted on parents using questionnaires including general characteristics, eating behavior, and food habits at home and food preferences of children in 6 nursery facilities. The children involved in this study were 150 boys and 154 girls, aged 1 to 7 years old. Sixty three percent(187 children) of the children were on 'regular' meal times, and 37.0%(110 children) were on 'irregular' meal times. The major reason for their irregular meal times were 'their' concentration on other tasks'(26.6%) and 'no appetite'(25.5%). The meal eaten best by children was 'dinner' while that eaten worst was 'breakfast'. The major type of their eating habit problem was 'unbalanced diet'(62.1%), and their mothers' response to the unbalanced diet was 'trying to persuade the child'(71.6%). The number of snacks at home was one or twice a day(97.3%), and 'preference'(67.8%) was the main reason for selecting particular snacks. Their preferred staple foods were 'cooked rice with meat & vegetables and Chinese noodles', and 'noodles with bean sauce', and their preferred soup was 'seaweed soup' Also, their most preferred meat dishes were 'fried chicken' and 'thin sliced barbecued beef. Children preferred side dishes with animal foods to those with vegetable foods. Since children liked mixed dishes, it seems desirable to introduce foods which children dislike as ingredients in mixed dishes.

  • The policy regime of ocean is changed from ocean liberty paradigm to ocean management paradigm. Ocean resources have the characteristics of weak excludability and strong rivalry. Therefore, they need rational ocean management so as to curb the tragedy of commons. The important ocean issues and policy regimes today is ocean pollution, coastal management, sea-level rise, fishery, whaling, ocean jurisdictions, deep seabed resources, military security, piracy, ecological environmental security and so on. This paper aims at reviewing these major international ocean issues, the policy regimes for them, and the desirable tasks of ocean policy regimes in the future from the macro perspective of international ocean politics or policy-making.

  • This paper discussed environmental health policies for the past and coming decade by reviewing the First Comprehensive Environmental Health Plan (2011~2020) and introducing the Second Comprehensive Environmental Health Plan (2021~2030). The major achievement of the First Comprehensive Environmental Health Plan was the establishment of receptor-oriented environmental health policies. However, the main limitations were insufficient policy support for relief and/or recovery from environmental pollution damage and low public awareness of environmental health policies. The Second Comprehensive Environmental Health Plan presents the following major policy tasks: establish an omnidirectional environment health investigation and monitoring system, provide customized environmental health services, improve the environmental health damage relief and recovery system, and promote regional environmental health policies. The Second Plan has a clear distinction from the First Plan in that it expands the field of environmental health from the prevention and management of environmental risk factors to proactive damage response and recovery, which will effectively contribute to alleviating the burden of environmental disease.

  • Mangyeong River and Dongjin River are highly dependent on external regions for domestic and agricultural water, and the agricultural water supply and use system of those rivers are very complicated. For smooth water supply, rivers are used as a supply system. Of the total river water use permits (as of 2019), agricultural water accounts for 97.5%, 80.4% in Mangyeong River and Dongjin River, respectively. The excessive intake of river water as agricultural purpose is causing the stream to dry out and to deteriorate the ecological health of the river. It is necessary to minimize the water use system that takes in and utilizes river water. In both rivers, the flow rate of agricultural drainage and the load of major water quality items that flowing into the main stream are similar to or higher than those of the major tributaries, indicating that management is necessary to improve the water quality of the river. It is necessary to understand the effect of agricultural drainage on river water quality by establishing a continuous monitoring system for the form of agricultural drainage.

  • This study analyzed the allocation of the skipper's attention during fishing operation in the wheelhouse of a Korean coastal composite fishing vessel by using video observation. To summarize the results, the ratio of lookout, radar and GPS monitoring, which is essential for prevention of collision at sea, was significantly lower than that of other fishing operation due to the attention concentration on the work place during hauling line. In order to reduce exposure to risk of collisions due to concentration of attention to certain tasks such as line hauling, it is necessary to develop an alert system that can notify the approach of other ships or obstruction throughout the ship using information from radar or the automatic identification system. In addition, the order of attention allocation to devices and facilities obtained in this study is expected to be used as basic data for device or facility layout based on the principle of usage frequency in designing wheelhouse for coastal composite fishing vessels in the future.

  • Construction industry, which is a composite industry being performed by organic combination of various tasks, gives birth to a various of information in the stages of planning, designing, and maintenance management. In particular, the drawing information is broad in the scope of use because it contains all information about buildings as wall as bid, materials, contracts. Therefore, the management of drawing information security is one of the most important factors, which determines the success of failure of business. The major findings and result of this study are as follows to control the distributed drawing information in the collaboration environment. 1) Analysis for function and practical use of DRM in the construction industry. 2) Proposal for applications of DRM that can secure IFC model-based drawing information in the collaboration environment. 3) Extraction from additional IFC entities to apply DRM to part 21 physical files 4) Analysis for functions which are necessary in DRM application prototype system and development of the system. 5) Development IFC model-based DRM prototype system.

  • This study reviews several database menu structure for pc communication services to examine the efficiency of database menu structure. Database menu systems of 5 major pc communication companies were analyzed by GOMS methodology, a description of the knowledge that a user must have in order to carry out tasks on system. Also, each database access time of 4 pc communication companies were measured with internet pc environment in laboratory. It is recommened that another menu design strategies (for example, broad-shallow rather than narrow-deep) should be adopted because current menu structures have inefficient procedures to access those database.

  • As the global environmental crisis has been emerged as an important problem threatening the survival of the mankind, the environmental problems are recognized as a great issue governing the destiny of the whole mankind as well as a national problem. Therefore, more active attitude playing a leading role of global and local environmental preservation is required, escaping from conventional passive position for the minimization of economic damages according to global environment regulations. This study evaluates the 150 university students' consciousnesses and attitudes of the seriousness, major policies and issues of environmental pollutions, extracts their consciousness of environment and practicable tasks for the 21st century and is to give the basic reference materials of environmental policy development.

  • Musculoskeletal disorders(MSDs) are one of the major issues in shipbuilding industry. Main risk factors of MSDs include manual handling of heavy weight, awkward posture, repetitive tasks, prolonged static muscle contraction, and so on. in this study, Using the three-dimensional digital human modeling and simulation method we made up a worker and work posture on a virtual environment. To verify this simulation we compared both traditional ergonomic analysis on a real worker and digital program analysis on a digital human. And this paper shows that it is possible to reduce the rate of MSDs in the shipbuilding industry because it means we can change poor posture mid surroundings into better ones.
