In the analysis of function, which is the core and early phase among the procedure of construction VE Job Plan, the accuracy of function definition directly connects to VE result. However, the method of defining function, which is currently used is not accurate and comprehended or is difficult to utilize it systematically. Also, there is not a clear definition about the function for selecting VE so that many difficulties occur in the organic connection between each of functions in the summarization of function after defining function. Therefore, this study cleared the definition of function and made up any counter measured problem occurred in FAST Diagram later on and suggested CAFAT(Combined Antithetic Function Analysis Technique) in order to induce better phase in functional analysis.

Purpose: To compare the outcome of two methods of chronic calcific tendinitis (CCT) treatment, Multiple drilling alone versus combined drilling and extracorporeal shock-wave therapy (ESWT). Furthermore, to analyze the clinical and radiologic results of different energy level configurations of ESWT. Materials and Methods: Among the patients complaining shoulder pain who visited the clinic from June 2010 to August 2011, 98 were diagnosed with CCT of the supraspinatus and were divided into the following three groups. Multiple drilling alone (n=31), Multiple drilling followed by high-energy ESWT (n=31), Multiple drilling followed by low-energy ESWT (n=36). The study was conducted only with patients with chronic pain persisting longer than six months despite prolonged conservative therapy. Clinical evaluation was done before and after 12 weeks from treatment, in clinical terms using the ASES, KSS, CSS system reflecting performance and symptom improvement, and in radiologic terms by studying the change in size of the calcific nodules. Results: All of three groups showed effects for improvement of clinical function and decrease of calcification and clinical improvement was significantly high in comparison between the group fulfilled by only multiple needling (the third group) and the group fulfilled by additional ESWT (the first and second groups) and in the radiological evaluation, calcification size and the rate of calcification decrease showed significant improvement statistically. For the comparison among the groups, degree of clinical function improvement and rate of calcification decrease showed significant difference between high energy group (the first group) and multiple needling group (the third group) as well as low energy group (the second group) and multiple needling group (the third group). But, in comparison between high energy group (the first group) and low energy group (the second group), there was no significant difference for the degree of clinical function improvement and rate of calcification decrease. Conclusion: For the treatment of chronic calcific tendinitis, additional ESWT showed more superior effects on clinical function improvement and radiological improvement regardless of the energy standard rather than the exclusive fulfillment of needling. But, as the result of ESWT by the energy standard, there was no significant difference for the decrease of calcification and degree of clinical function improvement.

A new algorithm is proposed for training the multilayer perceptrion(MLP) in pattern classification problems to accelerate the learning speed. It is shown that the sigmoid activation function of the output node can have deterimental effect on the performance of learning. To overcome this detrimental effect and to use the information fully in supervised learning, an objective function for binary modes is proposed. This objective function is composed with two new output activation functions which are selectively used depending on desired values of training patterns. The effect of the objective function is analyzed and a training algorithm is proposed based on this. Its performance is tested in several examples. Simulation results show that the performance of the proposed method is better than that of the conventional error back propagation (EBP) method.

Used analog control systems have been converted into digital control systems due to performance degradation and difficulty of maintenance. There are few domestic DCS (Distribued Control System)s that have been applied to power plant. To apply a domestic DCS to power plant, the reliability, redundacny, and fault tolerance of DCS is important. Besides those items, the control action of control function block is also important. In this paper, we describe the requirements that PID control function block has to have, and implement a PID control function block that satisfies those requirements. Finally, real control result using an implemented PID function block in thermal power plant shows the validity of an implemented PID control function block.

The Ministry of Land, Infrastructure and Transport was developed the Construction CALS system for improvement of the construction economy. Construction CALS system is consist by Construction Portal System, Construction Management System, Construction Authorization and Permission System, Compensation Management System, Facility Maintenance Management System and has utilized at construction site of more than 900. Ministry of Land, Infrastructure and Transport and related researcher was proposed method of various function improvements for usability of the system. However, the proposed method was expanded the problems like increase of system management cost and development cost with decrease of data process rate. The problem was increases because has added of only service function without modify of software structure to the system on each different platform base. One of the methods for solving problems is to apply the e-Government framework and then integrated the different platform. The purpose of this paper is analyse of the applicability and efficiency of e-Government framework to the construction CALS system. For that was analyzed the e-Government standard framework and the developments case. And then was verified about the adaption possibility and efficiency by use the Function Point tool.

Purpose: Recently, many quality issues are aroused in military forces, such as failures in K-series weapons, combat boots defects and 40mm ammunition explosion accident. To address these problems, this paper suggests to use so called, Defense Quality Score, which is based on Taguchi loss function and developed in this research. Methods: Current defense specification states only the minimum requirement to produce the military supplies. Therefore, it is not easy to indue the continuous quality improvement of the supplies. This research suggests to use the defense quality score which measures the current status of defense supplies'quality characteristics. Results: We applied the defense quality score concept into the hot pepper sauce and long time stockpiled ammunition. We first categorize the quality characteristics into three categories, then assign the certain amount of score based on the importance of the characteristics. Lastly, we applied the modified Taguchi loss function to calculate the achieved score of the characteristics. The perfect score is 100 and the closer to the score, the better product it indicates. Conclusions: In this research, we developed the modified Taguchi loss function to apply into the korean defense supplies. The loss function is utilized to calculate the achieved level of satisfaction of the supplies based on the defense specifications. The application of defense quality score may help to stimulate the continuous quality improvement and encourage the good will quality competition among the military providers.

This study investigated the administrative history, from the introduction of the "Standard of Government Function Classification" (BRM) to its development and application. Through the results of the survey, the causes of the problems observed in the current government's functional classification system were revealed. The current survey examined the functional classification scheme of the central government and local governments on the "cultural heritage" policy area (9 major functions, 59 middle functions, 297 small functions, and 1,287 unit tasks). It confirmed the problem of the separation of functions between central and local governments as well as other problems. Among the problems, this study proposed an improvement model through four representative cases such as the "designation of cultural heritage." In order to reorganize the "Standard of Government Function Classification," it is necessary to design a business function with the reproduction of tasks, establish a system for management and operation in order to maintain the consistency of the business function, educate users, and suggest continuous improvement.
