In general, fault of a virtually finished product that is value-added one, since it has gone throughout the most of processes, may give rise to quality cost nearly amount to its selling price and can be a main cause that decreases the efficiency of manufacturing process. This paper proposes a dispatching algorithm for manufacturing process with quality volatilities with consideration of due-dates and required quality level. In order to evaluate the proposed algorithm, this paper examines the performance of the proposed method by comparing it with that of the existing dispatching algorithms in terms of minimizing the mean tardiness. In addition, from the perspective of process capability based on required quality level, this study shows the superiority of the proposed dispatching algorithm.

The purpose of this study is to provide methods to improve the teaching of piano technique of intermediate-level learners through the works of Stephen Heller by focusing on rhythm and balance. Although a romantic-era composer, Stephen Heller's works are not well-known. However, when analyzing his compositions, many require the player to focus on their foundational piano techniques and musicality. Heller composed many interesting works including etudes that allow intermediate-level pianists to develop their musicality as much as those playing Chopin or Liszt from the same era. This study presents teaching methods for developing piano technique by focusing on rhythm and balance, and for enhancing musicality to improve the quality and significance of piano education and pedagogical research.

If the development of Integrated Logistics Support (ILS) for maintenance of the end step is conducted systematically and efficiently, the weapon system lifecycle can be postponed and the availability can be improved. DEFense CONdition (DEFCON) is maintained as perfect. Nevertheless, like its importance, the guide for maintaining the depot performance is applied differently for each weapon system. The errors that can result cause additional cost, etc. ILS development at depot level maintenance is different from full scale development. Therefore, this study distinguishes the management and deployment section for the development concept. An additional way to perform an efficient development of depot maintenance element when determining the depot maintenance period were presented. This study examined how the Reliability, Availability, Maintainability (RAM), Logistics Support Analysis (LSA), and ILS 11 elements intersect at the depot maintenance sources. An analytical study of concrete adoptable plans was performed. The systematic adoption of a development procedure can make it possible to calculate the adoptable development cost. In addition, it can be helpful for improving the quality level and practical use of work products.

This study examined the awareness levels of stroke warning symptoms and the related factors among residents in a province and this paper presents the evidence for education and promotion strategies. The study subjects were 585 adults living in a province. The demographic factors and awareness levels of stroke symptoms were surveyed through a telephone interview. In the survey, the most frequently recognized warning symptoms were 'sudden speech disturbance (84.6%)', and 'sudden weakness of one side (73.9%)'. On the other hand, 'sudden dizziness (67.0%)', 'sudden visual impairment (55.4%)' and 'sudden severe headache (51.3%)' were less recognized. In a multiple regression analysis, male, young age, no familial history of stroke, no acquaintance history of stroke, low educational level, no exposure to promotional literature were significantly related to a low awareness level of the stroke warning symptoms. Providing customized programs will be helpful for enhancing the efficiency of promotion and education to the population with a low awareness level of stroke symptoms.

This study analyzed the system level performance of the Mobile WiMAX-based TICN, and the effects of the use of BS-OTM in terms of the throughput of individual users as well as the overall system, assuming that other stationary BSs are distributed randomly. When BS-OTM is used, the CINRs decrease due to the additional interference from the BS-OTM from the perspective of SSs that are served by the same BS as when OTM BS is not used. On the other hand, from the perspective of SSs that had low CINRs, the CINRs increase significantly due to the new service from BS-OTM. Considering both effects, the cell throughput can be increased using BS-OTM. The CINR distribution and throughput of the overall system, changing the carrier frequency, position and velocity of the BS-OTM were also evaluated.

North Korea is now under the pressure of international sanctions due to its nuclear tests, firing of long-range ballistic missiles, the sinking of the ROK naval frigate the Cheonan, and the artillery attack on Yeonpyeong Island that killed four people. To overcome the burden of sanctions North Korea has exerted various efforts to reconstruct its industries. However, it is very unlikely that these reconstruction efforts would produce significant results due to the structural problems of the antiquated infrastructure of North Korean industries. In the future, it is expected that South Korea will have to cooperate with North Korea for the reconstruction of the North Korean economy after the North Korean nuclear issue will be peacefully resolved. South Korean government has to prepare for the reconstruction with careful planning based on analysis of North Korean industries. But, the number of previous studies that have analyzed the technological level of North Korean industries are quite limited. In preparation for the future inter-Korean industrial cooperation, this study tries to analyze the technological level of North Korean industries. The steel industry has been selected as the focus for the main analysis of this study due to the importance of the steel industry as one of key infrastructure industries. Additionally, this study tests the sustainability of the North Korean steel industry by looking into the possibility of whether the North Korean steel industry can sustain or grow while maintaining global competitiveness in the future when the market opens to the world. Such analysis is expected to contribute to the joint prosperity of two Koreas in the short term and the reduction of unification costs in long term.
