With a recent well-being boom, our interest in chemical-free vegetables is also increasing. So, some people are trying to take in wild plants chosen by themselves. However, others often come to their rescue in an emergency department after eating them, caused by their misunderstanding poisonous herbs as edible vegetables. We have ever seen two persons carried into the emergency department with bradycardia and shock incurred by his intake by confusion between Caltha palustris and Ligularia fischeri lately. There were symptoms such as epigastric pain, nausea, vomiting and so on in their cases, and the symptoms of bradycardia and hypotension continued. Owing to sustained bradycardia and hypotension states, we applied a dopamine to a patient, and then the in-patient left the hospital two days later. We presumed the cause of the two symptoms appeared in two cases to be a saponin in Caltha palustris. For that reason, if someone has the bradycardia and hypotension symptoms from an unknown cause after taking in wild plants, they have to consider a toxication by the Caltha palustris. Therefore, this paper focused on the issue that unexpected poisoning would have to be prevented by studying about wild plants much more and informing the toxic risk from the plants.

Due to economic development and increasing gross national income, the number of automobiles continues to rise, leading to a serious issue of illegal parking due to limited road conditions and insufficient parking facilities. Illegal parking causes significant inconvenience and displeasure to people and can even result in accidents and loss of lives. The severity of accidents and their consequences, related to the growing number of vehicles and illegal parking, is escalating, particularly in the metropolitan areas. Consequently, efforts are being made to address this problem as a cause of social issues and come up with measures to reduce illegal parking. In particular, half of the public complaints in the metropolitan area are related to illegal parking, and the highest physical and human damage occurs in Gyeonggi. Thus, this study aims to use machine learning techniques based on data related to illegal parking in Suwon city, Gyeonggi, to categorize regional characteristics and propose effective measures to crack down on illegal parking. Additionally, practical, social, policy, and legal measures to decrease illegal parking in the metropolitan area are suggested. This study has academic significance in that it solved the problem of illegal parking, which is mentioned as one of the social problems that cause traffic congestion, by classifying regional characteristics using K-prototype, a machine learning algorithm. Furthermore, the results of this study contribute to practical and social aspects by providing measures to decrease illegal parking in the metropolitan area.

The purpose of this paper is to explore Korean adolescents' understanding of safety using the indigenous psychologies approach. This paper examines Korean adolescents' experience of the type of accidents they were involved in, what they perceived to be the cause of the accident, the type of social support received after the accident, and the prevention needed to avoid future accidents. The indigenous understanding of accidents is examined according to the grade level of the students, gender, and safety efficacy beliefs. Second, to examine the changes in the safety efficacy beliefs, the differences across primary, junior high, and senior high school students are examined. Third, the relationship between safety efficacy belief and attitudes toward preventing future accidents is explored. Third, the parental influence on adolescents' safety efficacy belief is examined by analyzing the influence of their socio-economic status and their safety efficacy belief on their children's safety efficacy belief and behavior. The review of the results can be summarized into the following five main points: (1) decrease in safety efficacy belief with increasing age, (2) positive relationship between safety efficacy belief and behavior, (3) the utility of the indigenous psychologies approach, (4) the parental influence on their children's safety efficacy beliefs and behavior, and (5) the need to further explore, promote, and educate the importance of human life and quality of life by preventing accidents and promoting safety consciousness and behavior in Korea.

Medical Dispute Arbitration Law had been debated on its legislation several times since Korean Medical Association's submission of the bill to the National Assembly in 1988, eventually in December, 2009, passed the National Assembly Standing Committee and was laid before the Legislation and Judiciary Committee, and thus its legislation is now near at hand. During the long process, it has provided a hot issue with our society. And yet, Medical Dispute Arbitration Law has differed considerably in legislative content depending on the main body of proceeding the enactment, which subsequently was given the mixed comments of 'Act on Malpractice-related Damage Relief' or 'Medical Indemnity Act', and this legislative bill also cannot be free from this debate. It is desirable that medical disputes between doctors and patients be resolved through conciliation between the parties concerned. But, because reaching a compromise is difficult owing to deep emotional conflicts between the parties, difficulties in investigating a cause and requiring a high amount of settlement money, etc., it is inevitable to seek a resolution by third party intervention. By the way, such an arbitration by third party is based on the compromise of the interested parties and thus has a limitation of not being able to satisfy both parties completely. Therefore, the legislative bill made for arbitration of medical disputes between the parties will have to prepare an institutional system for the parties to easily understand and accept. Also, problems occurred in the legislative bill will have to be corrected through an in-depth discussion in order for the legislative bill to work as an effective system.

The Strategic Environmental Impact Assessment(SEIA) in Korea has been introduced and implemented for 15 policy-level plans and 86 project-level plans since 2012. Lately an important issue of the Environmental Impact Assessment(EIA) policy has been emerged regarding the expansion of the policy-level plans subjected to SEIA. Thus, we propose the plans that need to be included in the system, compared with those subjected to the Strategic Environmental Assessment(SEA) enforced in the law or the guideline of 10 foreign counties, especially with those of Germany, France, Italy, the United Kingdom, and Netherlands. Specifically the study suggests that plans related to energy as well as land use, which are well known to cause potential environmental impacts and subjected to the federal-level SEA in those countries, should be the subject of SEIA.

Noise and vibration due to pile driving cause residents nearby construction sites to file civil complaints and to the extent of bringing construction to a halt. To deal with this issue, construction engineers have worked strenuously to develop several types of low noise & low vibration pile methods. In this study, a new noise and vibration-free precast screw pile method proposed as a low noise & low vibration pile. It penetrates into the ground by rotating and pressing to avert noise and vibration while maximizing bearing capacity. A prototype of noise and vibration-free precast screw pile method was manufactured, which is not seen anywhere in Korea and elsewhere, and have undergone pilot tests twice to determine construction method. Based on this study, features of the noise & vibration-free screw pile method, production of screw concrete pile prototype, two pilot tests and subsequent construction method were determined.

The purpose of this research is to seek solutions in reducing shadow effects of construction projects on neighboring areas and as its result, we have yielded methods as below to mitigate shadow effects. To eliminate shadow effects fundamentally, revising building layouts to eliminate shadow effects by obtain construction site as much as two point two times of its height. But it will cause multiple problems such as economic inefficiency due to lack of construction sites as well as small sites that are often located in zones that are mixed with highly dense commercial and residential areas along with plan more parks on northern part of the construction site. Therefore, it is recommended to proceed Environmental affect evaluation for shadow effects and gain its residents permission prior to construction or revising building layout. In the other hand, the sunlight collector, which is one of the newly developed recycled energy, has been proven to improve illumination expected to become a reliable solution when dealing with shadow issue in and around high density residential areas.

An Remote Corrosion Monitoring (RCM) system consists of an anode with low potential, the metallic structures against corrosion, an electrode to provide reference potential, and a data-acquisition system to ensure the potential difference for anticorrosion. In more detail, the data-acquisition (DAQ) system monitors the potential difference between the metallic structures and a reference electrode to identify the correct potential level against the corrosion of the infrastructures. Then, the measured data are transmitted to a central office to remotely keep track of the status of the corrosion monitoring (CM) system. To date, the RCM system is designed to achieve low power consumption, so that it can be simply powered by batteries. However, due to memory effect and the limited number of recharge cycles, it can entail the maintenance fee or sometimes cause failure to protect the metallic structures. To address this issue, the low-overhead energy harvesting circuitry for the RCM systems has designed to replenish energy storage elements (ESEs) along with redeeming the leakage of supercapacitors. Our developed energy harvester can scavenge the ambient energy from the corrosion monitoring environments and store it as useful electrical energy for powering local data-acquisition systems. In particular, this paper considers the energy harvesting from potential difference due to galvanic corrosion between a metallic infrastructure and a permanent copper/copper sulfate reference electrode. In addition, supercapacitors are adopted as an ESE to compensate for or overcome the limitations of batteries. Experimental results show that our proposed harvesting schemes significantly reduce the overhead of the charging circuitry, which enable fully charging up to a 350-F supercapacitor under the low corrosion power of 3 mW (i.e., 1 V/3 mA).

Recently the construction of simulation environment is an important issue in all fields. In case of the training for operating machines such as airplanes or spaceships which cause a huge cost, simulators could be helpful to reduce the costs and training efforts by simulating real situations. When people get a driver's license, too many trainees have to wait for their turns because of the limited number of cars and the small space of training sites. To solve this problem, we have designed and developed the basic design for the simulators. We suggest the Computer 3D Simulation Model for a driver's practice. The concept of this simulator is from a 3D Racing-game which suits for a driving exercise. We provide users with handle-controlled simulation settings to let users feel reality as if they drive in real through this simulator. We also use a 'force-feedback' system which gives handle vibration when users collide against obstacles or exceed lanes. Users can be absorbed in the simulation program and feel the sense of the real. This paper is the study about modeling the driving exercise model of 'computer 3D simulation', and producing and utilizing the simulator through this modeling.

The use of antibiotics in Korean swine production has been changing to a restricted use of in-feed antibiotics. These antibiotics, which are also growth promoters, are powerful for disease control. Due to this issue, the swine industry is consistently looking for any kind of alternatives to antibiotics such as new feed ingredients, feed additives, feed formulation practices, or feeding methods to improve pig health and performance. In general, dietary factors provide bioavailable nutrients and/or affect physiological activity to modify the physiological condition, immune system, or microbial population of pigs to improve their performance and health. Thus, it is suggested that dietary factors may be important components in the growth and health management of pigs. Using an alternative grain feed such as rice, barley, and oats, low protein diets or low-high energy diets can be used as solutions to manage the effect of stress factors that cause growth and health problems at specific time points during the stages of pig production. Several studies support that these alternative feeds and dietary factors may improve pig growth and health by changes in intestinal conditions, immunity, or other physiological conditions compared with typical feed ingredients and diet management in pig production. Therefore, feed ingredients, low protein levels, and different energy contents in swine diets were reviewed to better understand how these dietary factors can contribute to improved pig performance and health under different physiological conditions.
