Innovation is considered as key to ensure continuous advancement and firm progress in any field. Robotics, with no exception, has gained triumph and approval based on its strength to address divers range of applications as well as its capacity to adapt new ways and means to enhance its applicability. The core of novelty in robotics technology is the perpetual curiosity of human beings to imitate natural systems. This desire urges to continuously explore and find new feet. In the past, contemporary machines, in different shapes, sizes and capabilities, were developed that can perform variety of tasks. The major advantage of these developments was the ability to exhibit superior control, strength and repeatability than the corresponding systems they were replicating. However, these systems were rigid and composed of hard an underlying structure, which is a constraint in bringing into being the compliance that exists in natural organisms. Inspiration of achieving such compliance and to take the full advantage of the design scheme of biological systems compelled researchers and scientists to develop systems avoiding conventional rigid structures. This ambition, to produce biological duos, needs soft and more flexible materials and structures to realize innovative robotic systems. This new footpath to craft biological mockups facilitates further to exploit new materials, novel design methodologies and new control techniques. This paper presents an appraisal on such innovative comprehensions, conferring to their design specific importance. This demonstration is potentially useful to prompt the novelty of soft robotics.

OSHA(Occupational Safety and Health Act) generally regulates employer's business principles in the workplace to maintain safety environment. This act has the fundamental purpose to protect employee's safety and health in the workplace by reducing industrial accidents. Authors tried to investigate the correlation between 'occupational injuries and illnesses' and level of regulation compliance using Survey on Current Status of Occupational Safety & Health data by the various statistical methods, such as generalized regression analysis, logistic regression analysis and poison regression analysis in order to compare the results of those methods. The results have shown that the significant affecting compliance factors were different among those statistical methods. This means that specific interpretation should be considered based on each statistical method. In the future, relevant statistical technique will be developed considering the distribution type of occupational injuries.

The effect of reticuloendothelial hyperfunction on hypothermic preservation of lung was studied in dogs. In order to evaluate the viability after hemodynamic_ load in preserved isolated lung, observations were made on the rate of increase in weight, degree of edema,compliance and surface activity of lung. The results obtained as follows: l. In the group of activating of the reticuloendothelial system by injection of sodium thiosulfate intravenously before pneumonectomy and infusion of naphthionine through the pulmonary artery before hypothermic preservation of isolated lung the limit of preservation was eight hours whereas four hours in non-treated control group. 2.Therefore the method of activating of the reticuloendothelial system before and after pulmonary resection seems effective in preserving for prolonging the period of preservation of lung by means of inhibition of pulmonary edema. 3. Pulmonary surface activity is expected to be valuable as a method in evaluation of the viability of preserved lung along with compliance and rate of increase in weight of lung.

The statistics of Korean Maritime Safety Tribunal and Japan Marine Accidents Inquiry Agency shows that the major muses of collision at sea are Improper lookout and Non-compliance with marine traffic rules. Those two muses are occupying more than 70% of collision, and it's clear that those muses are undoubtedly closely related to simple human error. In this paper we tried to find out the root muses of this kind of human error of OOWs(officers on watch) through risk identification method and studied how to tackle them via risk control theory. In conclusion, the measures studied in this paper could be applied to help OOWs avoid their own human error as well as be used in shipping company for their fleets' safety management.

In this study, the wedge splitting test (WST) specimens with various strength levels were tested to investigate the fatigue crack growth behavior of concrete. Selected test variables were concrete compressive strength with 2 levels (28 MPa, 60 MPa, 100 MPa) and maximum fatigue loading with 2 levels (75%, 85%). Fatigue testing was preceded by fracture energy test and the crack growth was measured by means of the compliance calibration method, 60 WST specimens were cast for the fatigue test, and 6 companion cylinders ($\phi$100${\times}$ 200 mm) for each batch. In fatigue test, the frequency of loading cycle was 1 Hz, and the minimum fatigue loading level was 5~10 % of ultimate monotonic loading. On the basis of the experimental results, a fracture mechanics-based empirical relationships for fatigue crack growth rate (da/dN-$\Delta$KI relationships) were presented. In addition, the effect of initial notch depth on the fracture energy and the validity of compliance calibration technique for the WST were shown.

Under the UN Security Council Resolution 1540/1810 in 2004 to restrict the proliferation of WMD (weapons of mass destruction) and their means of delivery, many countries have taken great efforts to, control the export of strategic items, thereby preventing the transfer of ABCM (atomic, biological, chemical weapons, missiles) and technologies and goods related to conventional weapons or dual-use items, Compliance Program (CP) in Korea or Internal Compliance Program(ICP) in Japan refers to a company's internal system or rules to comply with the export control laws and regulations, and is to prevent the unintentional illegal export of strategic items. This paper analyzes the Compliance Program (CP) of strategic export control system between Korea and Japan. Both countries have very similar legal frameworks under the guiding principles of multilateral export control regimes. However, there are some differences in actual procedures, classification service, supporting system, export license, sanctions for illegal exporters, etc. Korea should take more active and customer-oriented measures to promote the Compliance Program (CP) into Korean export companies for better awareness and positive attitude, practical information and education, smoothy government-firm communication, closer cooperation between Korea and Japan, etc.

The purpose of this study was to determine an effect of the health camp program on self-efficacy, sick-role behavioral compliance and glucose metabolism in juvenile diabetes mellitus patients. The quasi -experimental study was designed using a nonequivalent control group pre-posttest design with the framework of Bandura's self-efficacy theory. Forty-two juvenile diabetes mellitus patients participating in this study were selected from outpatients. Of these, twenty-one were assigned to the experimental group and twenty-one to the control group. The period of data collection was from August 8 to December 9 in 1994. The health camp program for the experimental group was carried out over 6 days and the control group did not participate in the program. Collection data was analyzed by means of chi - square test, t - test, ANCOVA, Pearson correlation with SPSS /PC+. The result were summarized as follows: 1. The health camp program was effective in in-creasing the scores of self-efficacy for juven-ile diabetes mellitus patients. 2. The health camp program was effective in increasing the scores of sick - role behavioral compliance for juvenile diabetes mellitus patients. 3. The health camp program was not effective in decreasing the levels of glucose metabolism. 4. The more self-efficacy increased, the more sick - role behavioral compliance increased. 5. Boys showed the higher self-efficacy than girls and the group with diabetes patients whose family members are also patients, showed the higher self-efficacy and sick-role behavioral compliance than the group without diabetic patient among the family members. Thus, it can be concluded that the health camp program was a useful health intervention for juvenile diabetes mellitus patients.
