This paper research an answer to the question what is the relation between intrinsic value of truth and substantiality of truth. The concept of substantiality can be variably defined, but I characterize it as being an opaque concept. Michael P. Lynch, who is one of the most influential pluralists about truth, accept both that truth is substantial and that truth is intrinsically valuable. This paper analyzes Lynch's argument for the intrinsic value of truth, and will show that his argument is independent of his theory which insists that truth is manifested plurally. Moreover I will discuss how Paul Horwich who is a deflationist denying substantiality of truth explains the intrinsic value of truth. And comparing these two views, I will elaborate the reason why intrinsic value of truth and its substantiality are logically independent each other. Finally, I will suggest a brief case which shows an implication included in the conclusion that plural manifestation of truth does not generally entails plurality of value of truth.

In general, deflection limit criteria of bridge design specifications have been considered based on static serviceability and structural stability. Dynamic serviceability induced from bridge vibration actually has not been included in the criteria. Thus, it is necessary for deflection limit to be considered in order to check dynamic service- ability on bridge vibration. In this study, The allowable displacement of Korea Railway Bridge Design Specifications is compared to the frequency domain comfort limit and analyzed france code and japanese code. Korea Railway Bridge Design Specifications is regulated based on the train speed. Such is because the vibration time duration is partly considered. but this criteria is not satisfied with comfort limit. and, it is estimated to be capable to provide deflection limit considering dynamic serviceability. In order to evaluate the dynamic serviceability of various types of railway bridges in current public were selected and their dynamic signals were measured. and the result of the bridge-train interaction analysis according to the changes in bridge stiffness was compared to the comfort limit to suggest the stiff-ness limit to the dynamic serviceability, which should conveniently be applied at the field.

This paper investigates whether the value relevance of unbilled revenue in the construction company is differentiated according to the degree of company's operational efficiency. Unbilled revenue is an item that appears in the assets of the statement of financial position based on the IFRS. It is an item that has a nature of accounts receivable, but it is calculated based on subjective judgment of management. In this paper, we hypothesized that the value relevance of unbilled revenue will be differentiated according to operational efficiency of the construction company. The results of hypothesis test are as follows. First, unbilled revenue has a significant relationship with firm's value, which is consistent with previous research results. Second, the value relevance of unbilled revenue is higher in companies with high operational efficiency. In conclusion, this paper is different from previous researches in that this paper presents not only that unbilled revenue has a value relevance but also provides evidence that it can be differentiated according to the degree of operational efficiency.

In a sensitivity analysis, an uncertainty importance measure is often used to assess how much uncertainty of an output is attributable to the uncertainty of an input, and thus, to identify those inputs whose uncertainties need to be reduced to effectively reduce the uncertainty of output. A function is called monotonic if the output is either increasing or decreasing with respect to any of the inputs. In this paper, for a monotonic function, we propose a method for evaluating the measure which assesses the expected percentage reduction in the variance of output due to ascertaining the value of input. The proposed method can be applied to the case that the output is expressed as linear and nonlinear monotonic functions of inputs, and that the input follows symmetric and asymmetric distributions. In addition, the proposed method provides a stable uncertainty importance of each input by discretizing the distribution of input to the discrete distribution. However, the proposed method is computationally demanding since it is based on Monte Carlo simulation.

George Canguilhem(1904-1995) is one of the rare French philosophers of the 20th century to develop an approach that was shaped by a medical education. For him, medicine is considered as "a technique or an art at the junction of many different sciences, rather than a proper science." The thesis that medicine is a technique is presented not at a practical level, but on an axiological horizon which reflects the totality of humanity. This character of medicine became a motive that concretized Canguilhem's philosophical thinking. Medical knowledge is not an application of physiology, but is derived from clinical observations which are based on the personal experiences of each patient. If medicine were based on scientific knowledge and its practice the very application of this pure knowledge, the patient might be a passive object. However, the patient doesn't remain passive, but reacts to the menace of disease according to attitude that the patient developed over the course of his or her life. Canguilhem characterizes this point as 'normativity', the core of individual life, which eludes positivist medicine. Here appear the essential contents of his vitalism. Although they emphasized the activity of individual living being, other modern French vitalists didn't consider this dimension of norms. Since the normativity in Canguilhem concerns the subjectivity of the first person, it avoids a mechanical form of explanation. Thus Canguilhem's originality is found in his derivation of the essence of medicine from individuality, values and norms.

The purpose of this study is to specify a structural relationship among learning goal orientation(LGO), creativity, working smart, working hard, and work performance of salespersons, verify the direct and indirect effect of variables, and examine impacts of the five factors at the same time. Also, this carried out the study to understand the relationship between the salesperson's creativity and work performance. This study targeted for salespersons who were working in various industries and total 588 were participated via on-line. According to the study, the result is as follows. First of all, There are direct effects among LGO, creativity, working smart, and work performance. However, working hard didn't have any direct effect with any other variables. Creativity and working smart have indirect effects on the relationship between LGO and job performance. In addition, the mediating effect of the model with creativity was higher than that of the model without creativity. Therefore, creativity is an individual competency that should be continuously developed to improve the work performance of a salesperson.

This paper is to measure and ealuates the technical efficiency, pure technical efficiency and scale efficiency with three inputs and two outputs with the use of DEA(data envelopment analysis) in Korean RCC(Rescue Co-ordination Center/RSC(Rescue Sub-Center). Several conclusion emerge. first the average efficiency of overall technical efficiency measure about $91.03\%$ and pure technical efficiency $96.80\%$ is much large then scale efficiency $93.83\%$. It means that inefficiency has much more to do whit the inefficient utilization of resources rather then the scale of production. second, DRS(decreasing return to scale) is Tongyeong and IRS(increasing return to scale) is Incheon, Taean, Gunsan, Yeosu, Ulsan, Donghae in RCC/RSC. finally, inefficiency RCC/RSC. have to benchmarking with reference sets.

There has been a lot of discussion to revise military helicopter crashworthiness design criteria. In this paper, newly revised crashworthiness criteria is analyzed centering around the Crashworthiness Index which is the core content of revised criteria. The Crashworthiness Index(CI) was conceived as an adequate method to quantify the crashworthiness capabilities of a rotorcraft design. The index can rate how well a new or derivative design complies with design requirements. The CI rating is made up of seven assessment areas. While the Basic Airframe Crashworthiness(BAC) area tends to be an objective calculation, other areas of the CI tend to be more subjective. Therefore, in this paper, detail CI calculation process for the BAC area is analyzed to inspect the effectiveness of revised criteria.

Component-based development(CBD) has been generalized in industry to master the complexity and reduce the development cost and time. However, current CBD practice is developing the component which is dependent on single application[l][2]. Therefore component variability is emphasized to reuse the component in many family members in a domain[8]. However, components are developed for the reason of replaceability rather than the reusability which is the main purpose of the component due to the insufficiency of the study of component variability definition and type[3]. In this paper, we formally specify the component variability reflecting the characteristics of the component to increase the component reusability. We define the logic variability which was recognized as the existing component variability and we propose all types of variability existing in the component by suggesting three more variability types. And we propose the component variability scope which makes us estimate and verify the number of cases of the variability when we customize the component. We propose these component variability types and scope through formal specification. By applying these techniques in developing components, we can develop high quality components reusable in many family members.
