Wetlands considered to be an important natural resources because they provide biodiversity and habitat for species to breed and survive. In this regard, many countries in the world provide wetlands and have policies and laws to protect them. In Korea we hosted RAMSAR COP-10 at Changwon in 2008 representing Korea's endeavor to wetland protection. But, in the process of development Wetlands are easy target to be lost due its easy access and the laws and regulations to protect them are relatively weak. Thus, this research focused on the introduction of No Wetland Loss(NWL) and we can achieve wetland protection in the economy market ways. Thus, NWL should consider 1) a clear definition of NWL and harmony and consensus of introduction of NWL, 2) considering most wetlands be private we need a financial support for securing wetlands, 3) inventories for wetlands in Korea, draw a line of demarcation, technic to evaluate wetlands, 4) wetland restoration considering function of ecosystem not total amount of wetlands. Wetland protection should be a part of Basic Law of Water Management which in its progress and we need further studies on wetland protection because of watershed management, deserted agricultural paddies, etc.

Electric vehicles (EV) are developing fast during this decade due to drastic issues on the protection of environment and the shortage of energy sources, so new technologies allow the development of electric vehicles (EV) by means of electric motors associated with static converters. The proposed propulsion system consists of two induction motors (IM) that ensure the drive of the two back driving wheels. The electronic differential system ensures the robust control of the vehicle behavior on the road. It also allows controlling, independently, every driving wheel to turn at different speeds in any curve. This paper presents the study of an hybrid Fuzzy-sliding mode control (SMC) strategy for the electric vehicle driving wheels, stability improvement, in which the fuzzy logic system replace the discontinuous control action of the classical SMC law. Our electric vehicle fuzzy-sliding mode control's simulated in Matlab SIMULINK environment, the results obtained present the efficiency of the proposed control with no overshoot, the rising time is perfected with good disturbances rejections comparing with the classical control law.

As market is more and more mature, the survival environment of exporting companies is getting severer, which throws exporting companies into great pressures of the process of growth and development. For most businessmen, the hardest part of starting a foreign business is to find buyers or to get customers, which is more critical for small and medium-size foreign enterprises. The fast changes of internal and external trade and market circumstances, together with the advent of e-commerce, led to the diversified of the way to find foreign buyers for exporting companies. But the performance differs in using different ways of finding foreign buyers. Therefore, this study examines the status of the methods of finding foreign buyers and performance of exporting companies in China. Based on the investigation of the ways of finding foreign buyers, this study tries to find out the most efficient ways of finding foreign buyers for them. And this study tries to propose some practical suggestions for the exporting companies based on the analysis that will help them to improve companies' performances.

Purpose: The aim of this study was to compare the "Physical Therapist and Occupational Therapist Act" of Japan and the "Medical Technician's. Etc. Act" of Korea in order to establish the grounds for improvement of effective law-making. Methods: We obtained the "Medical Technician's. Etc. Act" from the Korean Ministry of Government Legislation and the "Physical Therapist and Occupational Therapist Act" from the Japanese Ministry of Health, Labor and Welfare. It was translated from an association by related Japanese and experts. Results: The laws consisted of acts, enforcement ordinances, and enforcement regulations in both Korea and Japan. In the Korean case, eight occupations were defined in one law including six types of medical technicians, as well as medical recorders and opticians. The "Physical Therapist and Occupational Therapist Act" in Japan is composed of 6 chapters and 22 articles, while the Korean Act consists of 33 articles without chapters. Among them, 11 articles covered the establishment and management of dental laboratories and eyeglass shops, and only 22 articles were related to physical therapists and occupational therapists. Conclusion: Independent laws should be established for each type of medical technician. They must be comparable to Japanese laws on physical therapists and occupational therapists as well as clinical pathologists, dental hygienists, dental technicians, radiologic technologists, medical recorders, and opticians.

Mathematical models of industrial robots or manipulators are composed of highly nonlinear equations with nonlinear couplings between the variables of motions. These nonlin- earities were not considered important in the first stage that the working speed of the manipulator was not so fast, but the effect of nonlinear forces has become serious, as the working speed has been increased. So more improvement of performance cannot be expected by the control of manipulator using approximate linearization. As an approach for solving these problems, there is a method that eliminates nonlinear theory, which makes possible cecoupling of coupling terms and arbitrary arranging of poles is briefly introduced in this study. When the theory is applied to design the control law, its feasibility is examined whether the reasonable control results are obtained by simulating position, velocity, torque and tracing trajectory. The relations between the coefficients of the linearized differential equations and the maximum error and torque for the prescribed trajectory are also examined. Finally, the method for selecting the values for getting the most rapid and precise response within maximum torque of each drive is suggested in the choice of coefficients of characteristic equations which are obtained as a result of the control.

This study focused on the increasing fashion industry disputes that have resulted from the development of technology and industry. This study examines the improvement of domestic law, along with U.S. precedents that represents a larger fashion market and more legislative cases than Korea. Analyzing previous studies in Korea and the U.S. for theoretical background, it has uncovered limitations that apply to fashion design-related cases, rather than entire lawsuits involving various fashion industries. This study divided litigation into lawsuits involving products, human resources, and other lawsuits (such as incidents such as breach of contract, and portrait rights). Therefore, most lawsuits are related to products because of false socio-cultural perceptions about design imitation in the fashion industry. Lawsuits related to human resources are expected to arise due to the expansion of the Korean fashion industry and the expansion of overseas markets. Finally, new and unexpected conflicts will arise as the environment and social structure diversify. The importance of this study is that real case analysis can help reduce disputes because it can resolve legal instability due to the ambiguity of the interpretation of current law and suggest implications for dispute resolution.

Work related musculoskeletal disorders (WMSDs) became a major problem since 2000 in shipbuilding industry. WMSDs are known to be resulted from awkward postures, high repetitive motions, excessive forces, mechanical stress and vibration. Korean government enacted a law to require companies to take measures to prevent musculoskeletal disorders at work. If there are more than 10 incidences of WMSDs or 5 incidences which are more than 10 percent of all workers in a company, this law requires a company to implement an ergonomics program. A few large companies in shipbuilding industry have already implemented or are in the process of implementing an ergonomics program. This paper presents a case study of an implementation of an ergonomics program in a Korean shipbuilding company. We audited the process of the ergonomics program in this shipbuilding company four times for 3 years. Based on the findings, this paper presents effects and problems of an ergonomics program and improvement measures of them. These findings will help companies which want to implement an ergonomics program in the future.

This study is to deduce problems and grope for its solution by investigating the general operation status about the present fire investigation in Korea. As for the problems, this study is to point out that they are application of diversion by the function of law for fire investigation, execution of individualized fire investigation by each institution, total lack of information sharing system for fire investigation, and weakness of cause investigation for arson. The reform measures are as follows: the unity of law for fire investigation, joint investigation by the related institutions, early introduction of civil fire investigation expert system, extension of special research institutes for fire investigation, introduction of system for sharing information of fire investigation, and operation of fire investigation team for cause investigation for arson.

The purpose of this study was to investigate the relationship among staffing, occupancy rate, upward level change of long-term care need, and evaluation grade of facility. Data were obtained from National Health Insurance Corporation Database. Occupancy rate and evaluation grade were highest in National/public operating facilities, while they were worst in individual operating facilities. The percents of A or B grade in evaluation grade (by newly enforced law) is highest in National/public operating facilities. Multiple regression analysis showed that upward level change of care needs was very weakly associated with the number of doctors. Evaluation grade showed a weak and significant association with occupancy ratey(by old-version law)(r=.20, p<.01), upward level change of care need in group home(r=.23, p<.01) Staffing in facility did not show significantly consistent association with upward level change of care needs, evaluation grade, and occupancy rate.

The definition of an apartment is a building more than 5 stories high and which is the standard law. Currently, the number of apartments is increasing much faster than detached houses. Owning an apartment is a normal trend these days. However, the increasing number of apartments has been increasing the number of apartment fires which also has been making social problems. Therefore, this study was conducted for the fire extinguisher among other fire facilities because it is important for initial fire suppression. The research subject is on the fire extinguisher that is in the underground parking lot of 40 apartment complexes which are more than 10 stories. Survey and analysis were conducted for 80 fire extinguishers. There are two fire extinguishers for each apartment. The result of this study is that all installed fire extinguishers are ABC dry chemical type, 92% of them is 3.3kg and that meet the legal height(less than 1.5m). However, the condition such as appearance, inspection, manufactured year, appearance of signs, material of signs, size of signs, etc. was insufficiency. So improvement of law and system that are fire facility construction, maintenance implementation and additional designation of type approval about sign will be needed in my opinion.
