Korea's medical law prohibited medical advertisements in principle and permitted them on an exceptional cases. However, the decision of the Constitutional Court of 20005. 10. 27. 20003 Heonga 3, it was changed to a negative system which allows advertisements in principle and restricted only exceptionally. Dramatic increase of medical advertisements was made after that and many argued more deregulation because there was actually heavy regulations. In particular, there is almost no actual regulation on the article type advertisement due to the reason of protection of the freedom of press, media and occupation. However, there may be an unjust result if a specific article or specialists' opinion is made using a newspaper, broadcasting or magazine as a form of article type advertisement to specific medical specialists or medical institution or medical treatment method that falsifies consumers or makes consumers confused by unjust medical expectations or reliability, that also deteriorates just competition and that causes the misrecognition of consumers. In fact, there were actual damages of article type advertisements on the eye whitening surgery not long after the transfer to a negative system of medical advertisements. Victims raised a medical proceeding against the doctor who carried out the surgery, but there is actually no systematic warranty except for the indemnity request. Thus, this case demonstrated a vulnerable result of a negative system. As such, it is problematic that there is no proper regulations defined in the current law and regulations because of the reason of the protection of the freedom of press, publication and occupation despite damages of such article type advertisements. Accordingly, it is urgent to apply the current prevention regulations on the article type advertisements strictly, and to set up specific regulations.

Products liability refers to the liability of any or all parties along the chain of manufacture of any product for damage caused by that product. This includes the manufacturer of component parts (at the top of the chain), an assembling manufacturer, the wholesaler, and the retail store owner (at the bottom of the chain). Products containing inherent defects that cause harm to a consumer of the product, or someone to whom the product was loaned, given, etc., are the subjects of products liability suits. The goal of products liability system should be to maximize consumer welfare by efficiently providing just compensation for injuries incurred and deterring future injuries without unreasonably impeding the supply of the goods and services to consumers. Some advanced countries, apart from relying on products liability systems, also apply other policies and legislation directly aimed at the safety of the consumer. The application of general safety policies as well as products liability rules is not costless. An efficient system will not eliminate risk from society. An efficient system ... that maximises consumer welfare ... maximises the benefits while minimising the costs. Products liability claims can be based on negligence, strict liability, or breach of warranty of fitness depending on the jurisdiction where the claim is based. In view of international business and law circumstances, it should be stressed that international enterprises in Korea should consider how to cope with the situation of international transaction. International enterprises should have a correct perception about products liability which is to contribute the stabilization and improvement of the people's life and the sound develpement of the national economy. Products liability system creates incentives that influence behaviour and performance in ways that are desirable, such as more diligent monitoring to prevent defective products from reaching the market-place. At the same time, any liability system will impose burdens that are undesirable, such as greater costs imposed on business and consumers and reduced avaiability of consumer goods. The concern for society is to balance. The ideal situation is where the cost imposed on producers of goods and services pushes them to a desirable level of care but not so far that producers reach undesirable level of caution that may deprive consumers unnecessarily of the benefits from new and innovative products.

Piled snow upon PV module interferes with Photoelectric Effect process through photovoltaic directly. As a result of this phenomenon, its generation efficiencies keep decreasing or are stuck at zero power generating status. In addition, PV facilities have been installed on those places such as water surface, roof-top, and other isolated places, dealing with conditions of "Securing high REC weighted value", "Difficulty of securing land" and so forth. Through this study, we are able to actualize the function of heating over PV modules when it snows. We adopted laminating method through heating film and modules, guaranteeing warranty more than for 25 years. Also we are trying remote control systemically, not by hardware control, to run parallel with automatic driving and monitoring system which enable to control operation time, insolation, amount of snowfall automatically. We applied analysis of actual proof to both snow removal PV system and general PV power system, and these led to bear power consumption analysis while snow-removing, and its comparison after finishing the task as "One stone, two birds." In the long run, we could carry out economic analysis against snow removal system, and this helps to verify the most maximized control method for snow removal conditons on a basis of weather information. this study shall let prevent people from negligent accidents, and improve power generation problems as mentioned from the top. Ultimately, we expect to apply this system to heavy snowfall regions in winter season in spite of its limited system installaion in Korean territory, initially.

This study aims to configure what dimensions make up for smart phone after service quality, and how this service quality affects customer satisfaction and customer loyalty. Smart phone market is a market of the device leading the digital convergence as well as positioning itself as one of the national growth driving industry. To survive in this matured market, companies should have to respond actively to radical changes and customers needs in the so-called Smart Revolution environment. Lately, however, the smart phone market is prospected to move from growth phase to mature phase by the scholars. In order to proactively respond to the change in such market condition, companies need to provide absolute advantage in customer loyalty over their competitors by revolutionizing the after-sales service quality. Qualified A/S will lead to service satisfaction and achieve customer loyalty. The empirical analysis results obtained through A/S quality are as follows : First, human quality (attitude, expertise, problem-solvability), environment quality (handling agility, convenience, comfort), service policy quality (quality guarantee, additional service operation) are dimensions that make up for A/S quality. Second, A/S quality dimension showed a significant positive influence on service satisfaction and A/S satisfaction showed a positive influence on customer loyalty as well. Based on this empirical study, we propose some implications for A/S quality improvement. First, human quality dimension has relatively higher influence on A/S satisfaction in case of free A/S, so companies need to solve the product problem completely when consumer's first visit by continual employee education. Second, in case of paid A/S, the service policy quality-especially A/S Warranty period- has higher influence on A/S satisfaction.

Despite continuous efforts by the construction industry to achieve better quality, it doesn't seem that much has been improved. This is mainly because current specifications do not satisfy a change in the market environment, which is that a higher level of quality is now demanded by users. Quality improvement efforts have been satisfied merely to meet specifications. On the other hand, advanced countries have been experienced great success in their construction techniques and have reduced costs by introducing apay adjustment system to the construction industry, in which compensation is based on performance. Following their example, Koreashould introduce such a pay adjustment system in order to motivate the members of our construction industry to achieve better quality and a higher level of construction techniques. However, there has been a lack of a rational approach to the development of a system for cost coordination, as well as performance and quality inspection. Thus, in this study a legal and logical plan was developed that can be used to adjust the construction cost, along with the performance inspection of quality results, in order to introduce a pay adjustment system that is appropriate for domestic regulations.

In this study, a real-time crop recognition system was developed for an unmanned farm machine for upland farming. The crop recognition system was developed based on a stereo camera, and an image processing framework was proposed that consists of disparity matching, localization of crop area, and estimation of crop height with coordinate transformations. The performance was evaluated by attaching the crop recognition system to a tractor for five representative crops (cabbage, potato, sesame, radish, and soybean). The test condition was set at 3 levels of distances to the crop (100, 150, and 200 cm) and 5 levels of camera height (42, 44, 46, 48, and 50 cm). The mean relative error (MRE) was used to compare the height between the measured and estimated results. As a result, the MRE of Chinese cabbage was the lowest at 1.70%, and the MRE of soybean was the highest at 4.97%. It is considered that the MRE of the crop which has more similar distribution lower. the results showed that all crop height was estimated with less than 5% MRE. The developed crop recognition system can be applied to various agricultural machinery which enhances the accuracy of crop detection and its performance in various illumination conditions.

The goal of this study was to develop an accelerated life test for an implement working pump for an agricultural tractor. The field experiments were conducted to measure the load of an implement working pump during major agricultural operations such as plow tillage, rotary tillage, baler operations, and wrapping operations. The measurement system for an implement working pump load was constructed using a pressure sensor, the engine rotational speed, and the hitch pump displacement. The measured implement working pump load was calculated as an equivalent load for each agricultural operation using the Palmgren-Miner rule, which is a cumulative damage method. The equivalent load was calculated using the total load data and peak load data when the total data included the operation of an implement working. The annual usage time of the agricultural tractor was applied to develop two integrated equivalent loads. The acceleration factor was calculated to develop an accelerated life test and was calculated from the two integrated equivalent loads, the maximum pressure, and the flow rate conditions of the hitch pump. In Korea, the warranty life of a tractor is 2,736 hours, and the time required for the test to guarantee the operational life of tractors was calculated as 7,561 hours. The acceleration factors were calculated as 453.6 and 38.3, respectively, from the total load data and peak load data. The fatigue test time can be shortened by 16.7 and 197.4 hours according to the result of the acceleration factors.
