Purpose: The purpose of this study was to investigate the factors related to the academic burden on weight loss efforts among adolescents aged 12-18 in Korea. Methods: This study analyzed 29,069 obese adolescents (10.8%) using raw data of the 9th~12th the Korea Youth Risk Behavior Web-based Survey collected from 2013 to 2016. The data was analyzed using descriptive statistics, Chi-square and multivariate logistic regression. Results: Weight control efforts were significantly higher among girls, middle school students, those who are participating in nutrition education, and individuals with perceived fatness or perceived stress. Additionally, a long sitting time and high academic performance were found to be variables affecting the weight control efforts of adolescents. Conclusion: Obese adolescents in Korea spent a lot of time in their studies due to their academic burdens and this caused a lack of time to adjust their weight. Therefore, it is needed to establish a policy by considering these social and cultural factors for obese adolescents in Korea.

This study suggests a Healthcare System for elderly and disabled who have mobility impairment and use a wheelchair for long time. Seating long time in a wheelchair without reducing pressure causes high risk of developing pressure sores. Pressure sores come with great deal of pain and often lead to develop complication. Not only it takes time and effort to treat pressure sores but also increases medical expenses. Therefore, we will develop a device to help to prevent pressure sores by measuring pressure distribution while seating in a wheelchair and wirelessly send information to user device to check pressure distribution in real time. The equipment to measure body pressure is composed of FSR sitting mat which is a sensor measuring part and an user terminal which is a monitoring part. The designed mat is matrix formed FSR sensor to measure pressure. The sensor send measured data to the controller which is connected to the end of the mat, and then the collected data are sent to an user terminal through a bluetooth. Developing a pressure monitoring system will help to prevent those who have mobility impairment to manage pressure sores and furthermore relieve their burden of medical expenses.

Eletrophysiological methods revealed subclinical neuropathy in 26 workers, exposed from 1 to 17 years to lead and whose blood lead (PbB) values had never exceeded $70{\mu}g/100\;ml$, as ascertained by checking the monitor reports of the factory and by careful exposure history. The PbB determinations had been tested repostedly and had been found valid. The main findings were slowing of the maximal motor conduction velocities of the median and ulnar nerves and particularly the conduction velocity of the slower fibers of the ulnar nerve. Eletrophysiological abnormalities comprised fibriliations, diminution of the number of motor units on maximal contraction, and an abnormal. Thus, a dose-response relationship exlets on a group basis. Since the regular monitoring of PbBs in most workers during their entire period of exposure excludes the possibility of a body burden out of proportion to the PbBs silght neuro-logical damage is produced at exposures hitherto regarded as quite sale.

The demand of blasting work in civil engineering work is increasing because of the increasing social infra-structural construction work. The blasting method creates large benefit in regard to the economic aspect and shortening construction period. This method, however, has problems to be solved in respect to the blasting vibration and noise. Blasting vibration and noise have been studied by many workers, regarding to the impact on the structure and human body. This investigation is concerned on the affect of blasting vibration and noise on the animals which is relatively new. In general, animals have inferior mental capacity than human in hearing but have higher sensitivity on the vibration and noise due to blasting. The object of this study is to investigate an appropriate measurement of lessening damage on the animals by vibration and noise due to blasting.

Since 2003 when the prevention of work-related musculoskeletal disorders (WMSDs) became a responsibility of management in workplaces, the effectiveness of the Korean WMSDs law has been concern for many stakeholders of this measure including workers, workers' union, researchers, professionals, and managers as well as officials in governments. WMSDs are known to be resulted from overburden on workers' body due to tasks required at their workplaces. Korean government enacted a law to require management of companies to take measures to prevent musculoskeletal disorders at work. The objectives of this paper is to review activities and actions taken to comply with this WMSDs law and problems encountered in last 7 years since the law came intoforce and suggest resolutions for problems so that this law can contribute to fulfill the real purpose of the law and make better workplaces in Korea.

When you act for a good or just when you make a choice, you should ask yourself if the result of your action coincides with the principle that has generated it. Health and respect for our own individuality are two essential goods for the human being and also values that medicine itself should guard carefully remembering that its goal is to take care for a person and not only to cure a sick body. The means to achieve all this can only be a person-centered medicine which has the honor and the burden of considering the person (in the Kantian sense) and his health as an end, not a means. The current mainstream concept of health defined in 1948 by the World Health Organization as a state of complete mental, physical and social wellbeing and not merely the absence of disease and infirmity remind us that medical reasoning, based on the pathogenesis operator, is no longer sufficient in dealing with requests from the citizens: is now the right time to shift the focus from sickness to health giving emphasis to the salutogenic medicine approach.

In this research, a comprehensive study is performed upon the design of a quadruped walking robot. In advance, the walking posture and skeletal configuration of the vertebrate are analyzed to understand quadrupedal locomotion, and the roles of limbs during walking are investigated. From these, it is known that the forelimbs just play the role of supporting their body and help vault forward, while most of the propulsive force is generated by hind limbs. In addition, with the study of the stances on walking and energy efficiency, design criteria and control method for a quadruped walking robot are derived. The proposed controller, though it is simple, provides a useful framework for controlling a quadruped walking robot. In particular, introduciton of a new rhythmic pattern generator relieves the heavy computational burden because it does not need any computation on kinematics. Finally, the proposed method is validated via dynamic simulations and implementing in a quadruped walking robot, called AiDIN(Artificial Digitigrade for Natural Environment).

To evaluate the culture conditions in oyster-farming waters, chemical and biological measurements were made in seawater and oysters from six bays around Tongyeong in November and December 2003. Nutrient levels in the seawater were higher in the western area than in the eastern area, in contrast to particulate organic matter and dissolved oxygen levels. The mean total polycyclic aromatic hydrocarbon ({\sum}PAH) content of the oysters was 194.5-375.9 ng/g dry weight, with four-ring compounds constituting 34.1%-79.6% of PAH. Despite wide temporal variations, a "western > eastern" spatial distribution of PAH was apparent. These low concentrations of PAHs indicate that Tongyeong waters are pristine in terms of PAH contamination. Among the hemocytic biomarkers, only lysosomal activity was significantly reduced in Hansan-Goje Bay, but did not correlate closely with PAH content. This finding indicates that the impact of PAH on cultured oysters is negligible around Tongyeong waters.

After the Fukushima Daiichi accidents, public concerns on nuclear safety and the corresponding burden of nuclear power plant licensees are increasing. In order to secure public trust and enhance the rationality of current safety regulation, we develop a risk-informed decision making (RIDM) framework for the Korean regulatory body. By analyzing all the regulatory activities for nuclear power plants in Korea, eight action items are selected for RIDM implementation, with appropriate procedures developed for each. For two items in particular - the accident sequence precursor analysis (ASPA) and the significance determination process (SDP) - two customized risk evaluation software has been developed for field inspectors and probabilistic safety assessment experts, respectively. The effectiveness of the proposed RIDM framework is demonstrated by applying the ASPA procedure to 35 unplanned scrams and the SDP to 24 findings from periodic inspections.

In this paper, we propose 'a self - conformance system of convergence security provider' to provide basic data for security and reliability of convergence industrial technology, system and service. It is difficult to evaluate convergence security systems, limited to information and communication service providers, unable to check convergence security items, burden of submission documents, difficulty in measuring convergence security service level and we will summarize product and service-based requirements that can be integrated and systematically measure the level of convergence security and define renewed life cycle-based convergence security information and content security and assurance requirements. On the basis of this, each convergence security company declares conformity with the standard itself without the certification of the certification body, and introduces the provider conformity certification system which can manufacture and sell. This will enable the company to strengthen its competitiveness through timely launch and implementation of products and services and cost reduction.
