  • Electrical construction business has public and professional characters. It may require appropriate interventions of the government because these business activities stand for not only profit-seeking competition, but also supplies of one of the key functions in our society. In other words, public benefit and private benefit are still in existence. The government therefore considers such an aspect of public importance of the business sector and needs to plan to adjust technical and engineering manpower of this market. This study focuses on the imbalance for labor supply and demand of technical engineer in electrical construction business. A system dynamics analysis is applied to understand and simulate the imbalance as a soft approach. It has the merit of causal loop diagram to alleviate the limitation of data lack problem. We find that excess demand is expected from 2010 to 2011, and excess supply is predicted from 2012 to 2021 about the manpower of technical engineer. It shows considerable disagreement between the supply and demand of human resource. So we suggest that it is strong necessity to construct statistics infrastructure for a manpower supply and demand plan.

  • By prosperous condition of construction economy in the early 90s in korea, we needed a lot of the qualified professional engineers(PE) to manage the construction site. In order to meet the high demand of P.E., government has established the admitted engineer system(AES) which is given to admitted engineer who do not take the written exam but have equivalent working experience in 1995. However, since 2000, while professional engineer's shortage has been resolved, the opposite situation has occurred that is serious over-supply of construction engineers. Thus, government announced that will abolish the admitted engineer systems as recognized existent admitted engineers. However, Professional Engineers institution is insisting that must not recognize existent admitted engineer. From this point of view, it is critical to make the supply-demand forecast systems as a derivative approach of system dynamics also, that is useful in comparing the argument between government and Professional Engineers institution. This paper describes about qualified engineer's supply change by admitted engineer system abrogation and suggests the idea to regulate the supply and demand with the improvement of the regal system.

  • By prosperous condition of construction economy in the early 90s in Korea, the government needed a lot of the qualified professional engineers (PE) to manage the construction site. In order to meet the high demand of P.E., Government has established the admitted engineer systems(AES) in 1995 that give the authority of principal engineers to the admitted engineers who do not take the written examination but have equivalent working experience. Since 2000, professional $engineer^{\circ}{\phi}s$ shortage has been resolved. however, the opposite situation, which is serious over-supply of construction engineers has occurred. Thus, Government announced that would abolish the admitted engineer systems as recognized the existent admitted engineers(about 1,000,000 persons) from 2007. However, Professional Engineers Institution has strongly insisted that Government should not recognize existent admitted engineers. From this point of view, it is critical to make the supply-demand forecast systems as a derivative approach of System Dynamics also, that is useful in comparing the argument between Government and Professional Engineers Institution. This paper describes about principal $engineer^{\circ}{\phi}s$ supply change by admitted engineer system abrogation and suggests the idea to regulate the supply and demand with the improvement of the regal system.

  • Determining the hysteretic energy demand and dissipation capacity and level of damage of the structure to a predefined earthquake ground motion is a highly non-linear problem and is one of the questions involved in predicting the structure's response for low-performance levels (life safe, near collapse, collapse) in performance-based earthquake resistant design. Neural Network (NN) analysis offers an alternative approach for investigation of non-linear relationships in engineering problems. The results of NN yield a more realistic and accurate prediction. A NN model can help the engineer to predict the seismic performance of the structure and to design the structural elements, even when there is not adequate information at the early stages of the design process. The principal aim of this study is to develop and test multi-layered feedforward NNs trained with the back-propagation algorithm to model the non-linear relationship between the structural and ground motion parameters and the hysteretic energy demand in steel moment resisting frames. The approach adapted in this study was shown to be capable of providing accurate estimates of hysteretic energy demand by using the six design parameters.

  • Food sovereignty is the right of peoples to healthy and culturally appropriate food produced through ecologically sound and sustainable methods, and their right to define their own food and agriculture systems. An increase in the price of food that occurs as a result of increased demand from human consumption and use as an alternative energy resource. Furthermore, agflation, a combination of the words "agriculture" and "inflation", will also affect non-vegetative foods as the price increases for grain will make livestock feed more expensive as well. Food sovereignty implies new social relations free of oppression and inequality between men and women, peoples, racial groups, social classes and generations.

  • Construction Management (CM) is being utilized as an efficient project management system. Construction management system provide scientific management techniques as well as the expert's service with the expertise. Accordingly, CM services demand is continuously increasing in construction project. Construction Management engineer grade is distinguished by the Index of Construction Engineer's Competency (ICEC). Construction management engineer requires a higher score than the other fields. However, junior grade CM engineer can get grade according to the education and qualification. This study was conducted junior grade CM engineer depth interview after analyzing the problem of the current CM engineer grade system. As a result, this study was to extracted the 23 kind competence factors. And, competence factors were five area grouped using affinity diagram method. Next, we analyzed the importance utilizing the Analytic Network Process (ANP) technique. As a result, high priority areas were analyzed to be quality and cost areas associated with project management.

  • Gunpowder was invented as a result of discovering the fact that potassium nitrate acts as an oxygen carrier in the process of manufacturing traditional medicine by heating the mixture of potassium nitrate and sulfur. Rapid progress was made in dynamite manufactring technology as a result of development of basic chemistry in Europe. However, recently the demand for dynamite has decreased in favor of the ANFO explosive which is improved production technology. This study was attempted to clear the historical facts concerned with the developing process of European eaplosive technology, and intended to submitt the reference materials for researchers.

  • This paper presents long-term shunt capacitor planning using optimal power flow. OPF allows the planning engineer to find feasible solution with minimal amount of engineering time. We used OPF for Shunt capacitor planning to get an optimal solution. The result of OPF is compared to the analysis by the conventional loadflow method and it is proved that OPF gives more cheaper and better planning solution. With the result, we analyzed the operational perspective for the reactive power supply and demand.
