This study is aimed to improve safety of ladle in the metal products manufacturing industry. Burns may occur from spills, spatters or eruptions of hot metal from ladles during pouring or transporting. According to the statistics of occupational accidents about the ladle, many victims were exposed to or contacted with extreme temperatures. The many fatal injuries occurred as a result of unexpected discharging of molten metal due to tipping over ladles. To prevent ladles from turning over, the trunnion axis shall be located below the center of gravity of the ladle at all operating condition. For this purpose, the equation is proposed to calculate the minimum location of a trunnion axis for definite static stability when tilting.

Occupational fatal injury rate per 10,000 population of Korea is still higher among the OECD member countries. To prevent fatal injuries, the causes of accidents including human error should be analyzed and then appropriate countermeasures should be established. There was an severe converter furnace accident resulting in five people death by chocking in 2013. Although the accident type of the furnace accident was suffocation, many safety problems were included before reaching the death of suffocation. If the safety problems are reviewed throughly, the alternative measures based on the review would be very useful in preventing similar accidents. In this study, we investigated the converter furnace accident by using human error analysis and accident scenario analysis. As a result, it was found that the accident was caused by some human errors, inappropriate task sequence and lack of control in coordinating work by several subordinating companies. From the review of this case, the followings are suggested: First, systematic human error analysis should be included in the investigation of fatal injury accidents. Second, multi man-machine accident scenario analyis is useful in most of coordinating work. Third, the more provision of information on system state will lessen human errors. Fourth, the coordinating control in safety should be performed in the work conducting by several different companies.

The scale of construction industry recently tends to become bigger and larger in line with development of construction technologies and methods. Although increasing usage of construction machinery has led to improving productivity, reducing schedule and cost, constructions workers have been exposed to unstable work environment, causing more and more accidents. Construction machinery-related laws and regulations has not been enacted and reflected the conditions and circumstances of the construction industry in a timely manner. A various construction machinery and equipments produced and changed in structure randomly are so widely used that related-accidents may occure gradually. Propose a plan for accidents prevention through the analysis of characteristics and cases on construction machinery-related accidents over the past five years from 2009 to 2013.

There has been an increase in fire/explosion accidents caused by chemical substances used in new small/medium sized construction, reconstruction, or extension sites. There is vast room for improvement, especially in safety training, safety inspection, and selection of countermeasures because training, technicality, and management systems regarding fire·explosion risks in small/medium sized construction sites are very immature in most cases. The purpose of this study is to propose a differentiated technical, educational, and management application plan for preventative management of fire·explosion accidents caused by chemical substances used in small/medium sized construction sites.

Marine casualties originated from fishing vessel occupied about 70% of the whole marine casualties in Korea from 2001 to 2010, this ratio was not much changed as it was before. Therefore a pragmatic counterplan to decrease of casualties in fishing vessel is indispensable for reduction of the nationwide marine casualties. But since the casualties occurred by fishing vessel may have a different causes and counterplan according to the operating type of it, in this paper, fishing vessels classified into 12 types by operating method and inspected the causes and counterplan for that. The operating type of fishing vessel occurred the specific casualties more were jig boat in collisions and fire explosion, trap fishing boat, mixed fishing boats and inshore gill netter in collisions, stow netter in machinery damages and capsizing, offshore gill netter in machinery damages, fish carrier in collisions. It must be emphasized that the higher ranked types of vessels, especially jig boat have to take special care to the approaching vessels under way, trap fishing boat to rear look out and mixed fishing boat must keep on safety speed and be taken an education for advance the skill of operating radar as well. For all 12 types of fishing vessel, it is necessary for an operator to make strict precaution on the other vessel under way systematically and keep the regulation for preventing collisions, and for an engineer on watch to make a check the electricity and the engines periodically for reduction the fire explosion and machinery damages.

Digital dementia becomes an issue these days which causes failure of one’s memory and calculation ability because many people rely heavily on digital devices, such as smart phones. Smart devices themselves become smarter and smarter whereas digital device users become dumber and dumber, and finally they are suffering from digital dementia. Serious games can be defined as games which combine entertainments with various applications. They relieve the negative opinions which belong to existing games, so many game titles have been released as serious games in these days. This research is motivated by the fact that serious games were originated to overcome practical issues. In this paper, a serious game is presented to prevent digital dementia and its effectiveness is shown. The proposed serious game is composed of simple four fundamental arithmetic operations which improve one’s calculation ability. Since simple arithmetic operations are familiar regardless of one’s age, they are chosen. Everyone can enjoy the game beause random factors are added. This paper concludes that serious games can be used to prevent digital dementia very effectively.

Automobile was first introduced in 1903 in South Korea, the masses of the car was carried out rapidly compared to other countries. However, many people were killed in a traffic accidents and economic loss was occurred due to the spread of the automobile. In South Korea, 2012, traffic accident occurred 223,656 times, 5,392 fatality, 344,565 injured people. In the last five years, about 224,000 accidents per year were occurring. In other words, 610 traffic accidents occur and about 15 people pass away in one day. In addition, the proportion of traffic accidents is first place in the OECD countries and it is very high in the world. Understand occurrence tendency of traffic accident, accident frequency rate of the driver who drives more than 10 years was higher than the novice driver. In addition, as a result of examining the cause of the traffic accident, breach of safe driving obligation appears highest case (125,391 times), and followed by signal violation, break safety distance. Therefore, the majority of traffic accidents occurred by the lack of safety awareness of the driver. In this study, prevent the loss of human life and property in traffic disaster, by establish disaster prevention measures that investigated by questionnaire survey and statistical data of the state of consciousness and driving posture in response to the driving history of the driver.

We undertook the quantitative evaluations of Industrial Accident Prevention Program (IAPP). The six parameters, such as relevance, efficiency, consistency, sustainability, effectiveness, coherence, were chosen by expert plenary sessions. Two stage of Analytic Hierarchy Process were used to determine the weighted value of assessment criteria. This expert plenary suggests that the six parameters and its weight values are useful for quantitative evaluations of IAPP. Additional researches regarding the real world application of this assessment tool should be initiated.

As workplace incidents has been being declining in Korea, there is criticism of the effectiveness of occupational safety policy implementation. It is unknown that which policy target group needs to be targeted to yield effective injuries prevention. The purpose of this paper is to analyze and reveal the policy intervention group with a high priority in terms of industrial incident prevention and the related investment cost. A Policy Priority Model(PPM) is composed of 6 indicators regarding influences of both the incident reduction and the cost reduction. Z-score analyses are used to confirm the high policy priority area or policy target group. Overall, workplace with worker below 50 persons, construction site with the sales of more than a hundred million won, workplace with relatively small percentage of female employees and relatively higher percentage of older worker should be prioritized to reduce workplace injuries. This paper provides an analytic way that can be used to decide the policy priority workplace in order not only to reduce work-related injuries&illnesses and the related investment cost but to further lessen the related societal costs.

Century-old nutrition and health concepts can be revived and applied in the modern age in the forms of newly developed menus, recipes, and lifestyle education. Current medical nutrition therapy concepts were first described in the Chosun Dynasty (1392-1897) in Korea based on the philosophy that food and medicine originate from the same source, which is known as ‘food as medicine’. Recognizing the importance of culture, tradition, local diet, and lifestyle on health and medical nutrition therapy, we tried to rediscover traditional Korean approaches towards food consumption and nutrition through systematic review of the literature and developed contemporary menus accordingly. The medical nutrition therapy prescriptions described in ‘Shikryochanyo’ (1460) by the Chosun Dynasty’s royal physician Soonyi Jeao cover 45 different diseases. In this project, we developed contemporary menus for those disease models that are most prevalent in modern society. Menus developed with foods that are readily available today were evaluated for their nutritional content and adequacy using a computer-aided nutritional analysis program (CAN pro 3.0, developed by the Korean Nutrition Society for comparison with RDA for Koreans). Therefore, century-old nutrition and health concepts can be revived and applied in modern society as newly developed menus recipes and lifestyle education.
