  • The English language has developed from a language with optional subjecthood Into a language with obligatory subjecthood due to a general reduction of inflections. Two types of subject omission, pro-drop and conjunction reduction, have been reported in the history of English. Old English with rich inflections had both referential pro-drop and conjunction reduction. Middle English with much lesser inflections still witnessed pro-drop and conjunction reduction, but in such a decreasing way that modern English with a loss of inflections developed from Middle English hardly has either pro-drop or conjunction reduction. This paper explores both the phenomena relating to optional subjecthood in Old, Middle, and Modern English in light of the cognitive processes of the universal, hierarchical constraints that are assumed to be inherent in English speakers' cognitive fatuity. It is found that optional subjecthood in Old, Middle, and Modern English is correctly raptured in terms of the distinct rankings of the proposed constraints, and that it is closely related to whether each of Old, Middle, and Modern English has rich inflections.

  • This is case report of open reduction of condylar fractures with or without discal injury. Many articles described open reduction and internal fixation of condylar fractures emphasize the method of bony reduction and fixation without mention of the position of the disc. So we like to present our cases of open reduction of condylar fractures in conjunction with reconstruction of the disc and associated structures. The pupose of this presentation is to emphasize several well - established principles of trauma management and management of temporomandibular joint injuries, such as 1) in situations of traumatic injury, anatomic restoration is the goal of treatment and, 2) anatomic alignment of the TMJ disc over the condyle is preferable to disc subluxation because the latter may lead to chronic pain, limitation of opening and degenerative arthritis. Although our case is small with short term follow up, we believe that open reduction and internal fixation of condylar fractures in conjunction with disc repair is a biologically sound approach to those fractures indicated for open surgery. Long term follow up will allow better judge the validity of this treatment approach to us.

  • A joint problem of order delivery, setup reduction, and cost-sharing in a two-echelon inventory system in which a vendor supplies multiple products to a group of buyers is studied here. The basic premise is that buyers have independently implemented setup reduction programs to acquire benefits from small order sizes. Doing so, however, causes the buyers' individually optimal order cycles to be differ from that of the vendor. In conjunction with this, two models are considered. In the first model, a multi-buyers single product situation is considered in which the vendor implements a joint supply cycle policy. However, buyers, as the dominant party, insist after implementing the individually optimal setup reduction that the vendor accept their individually optimal order schedules. In the second model. a multi-products, single buyer situation is considered in which the buyer implements a joint order policy. Here, the vendor, as the dominant party, refuses to cooperate fully with the buyer's individually reduced joint order schedule, and designs his own individually optimal setup reduction mix for each product under a given budget constraint. This led to a study of an integrated Setup Reduction/Break-even Pricing Policy for each situation to eliminate mismatches in individually optimal cycle times.

  • Diesel $NO_x$ reduction by $NH_3$-SCR in conjunction with the effective oxidation precatalyst was analytically investigated. Physicochemical processes in regard to $NH_3$-SCR $NO_x$ reduction and catalytic NO-$NO_2$ conversion are formulated with detailed descriptions on the commanding reactions. A unified model is correctly validated with experimental data in terms of extents of $NO_x$ reduction by SCR and NO-$NO_2$ conversion by DOC. The present deterministic model based on the rate expressions of Langmuir-Hinshelwood reaction scheme finds a conversion extent directly. A series of numerical experiments concomitant with parametric analysis of the $NO_x$ reduction was conducted. $NO_x$ reduction is promoted in proportion to DOC volume ar lower temperatures and an opposite holds at lower space velocity and intermediate temperatures. $NO_x$ conversion is weakly correlated to the space velocity and the DOC volume at higher exhaust temperature. In DOC-SCR system, the $NO_x$ reduction efficiency depends on the $NH_3/NO_x$ ratio.

  • This paper presents the results of a comparative study between FEM and LEM on slope stability analysis. For validation, factors of safety were compared between FEM and LEM. The results from the two methods were in good agreement suggesting that the FEM with the shear strength reduction method can be effectively used on slope stability analyses. A series of analysis were then performed using the FEM for various constitutive laws, slope angles, flow rules, and the finite element discretizations. Among the findings, the finite element method in conjunction with the shear strength reduction method can provide reasonable results in terms of factor of safety. Also revealed is that the results of FEM can be significantly affected by the way in which the type of constitutive law and flow rule are selected.

  • In this paper, we describe the LPM structure with a two-phase, which is not used previously, and explain its operation principle. In order to predict the accurate performance of LPM reduction model, finite element model was derived and the back EMF of LPM reduction model was measured and compared. In order to investigate the thrust and normal force of the LPM reduction model, a driving circuit capable of applying two-phase pulse currents was constructed and the performance was predicted in conjunction with the finite element analysis model. Finally, the design considering actual LPM size was performed. Since the size of the reduction model is small, the field could be made of a permanent magnet. However, it is almost impossible to manufacture a permanent magnet to match the size and capacity of a real LPM for a vehicle, in terms of cost and writing. Therefore, the actual vehicle LPM was replaced by wound type that generates a magnetic field by applying current to the field winding, and the final model was derived using the reaction surface method.

  • The purpose of this paper is to review the occurrence, analytical methods and reduction methods of aflatoxins in foods. Aflatoxins are produced by the secondary metabolism of various fungal species and have the highest toxicity among mycotoxins. Due to their toxicity including carcinogenic activity, aflatoxins affect not only the health of humans ana animals but also the economics of agriculture and food. As a food-importing country, because aflatoxins could contaminate raw commodities and foodstuffs, there should be inspection on the exposure and the regulation of risk assessment as a food safety measure. In addition, studies on rapid analytical methods and reduction of toxicity by various processes for aflatoxins should be carried out in conjunction with those of the risk assessment of aflatoxins.

  • A dynamic system under random disturbance is considered in the study. In order to control the system efficiently, proper reduction of system dimension is indispensible in design stage. The reduction method using component cost analysis in conjunction with stochastic analysis is proposed for the control of a system. System response is obtained in terms of dynamic moment equation via Fokker-Plank-Kolmogorov(F-P-K) equation. The dynamic moment response of the system under random disturbance are reduced by using of deterministic version of component cost analysis. The reduced system via proposed "stochastic component cost analysis" is successfully implemented for dynamic response and shows remarkable control performance effectively utilizing "stochastic controller" in physical time domain.
