Environmental load reduction and sustainable development one of the study's research into the available material is discharged, remove the coarse aggregate and fine aggregate from waste concrete and utilizing the remaining cement fine powder as an alternative raw material for limestone is the main raw material of cement developing playback cement that was the purpose. Physical over existing research and chemical quality was confirmed was evaluated for durability by promoting carbonation test, research studies on the durability evaluation insignificant. As honipyul within the aggregate differential lung fine powder increases carbonation resistance performance've found that increased sharply and, S0 showed fairly similar to the OPC. Therefore, the development within the technology research to separate fine aggregate discharge fully differential and waste fine powder is determined to be the development and use of the playback durability of the cement with the carbonation levels corresponding to the OPC if made.

In recent years, public complaints about railroad noise by KTX and Ordinary train are increasing. Restriction of railways uses same standard without distinguishing the type of railways. According to the type of railways, the frequency characteristics of emitting noise is different. Therefore it is requested to know how vary the public response to each types of railway. The noise annoyance to three types of trains (KTX, Electric train, Diesel train) was analyzed by Jury Evaluation Test for assessing the effect of frequency characteristics. The numerical results by a Semantic Differential Method showed that annoyance response to three type of trains depended on the frequency characteristics. As a result, this study proposed that the KTX could have a bonus level of maximum 2.9dB(A) to ordinary train.

The purpose of this study is to evaluate the coastal nightscape of Yeong-Do in Busan in order to make an effective management plan of coastal nightscape. Firstly the coastal area of Yeong-Do has been divided into 8 nightscape sections. And then the nightscape images of each section have been evaluated by volunteer subjects through SD(semantic differential) analysis method.

This study is derived from relation between the natural landscape and architectural landscape. The type of landscape in Donghae seaside consist of three; Road, Mountain, Seaside. And we selected three landscapes about individual housing; Western, Traditional, Modern. This paper is analyzed 18-simulation scenes, which evaluated with semantic differential method in using 12-bipolar adjectives. The results of this study are as follows(ref: table 6). 1)The housing of western style do not correspond with landscape of Road, but landscape of mountain and seaside were suitable to the western style. 2)Mountain in Donghae seaside harmonizes with housing of traditional style. 3)Even though the housing of modern style were marked low assessment in three landscape, we found out relation, modern housing was well-matched with load landscape.

The purpose of this study was to evaluate the effect of reference fabric for the tactile sensation of worsted fabrics. As specimens, 32 worsted fabrics for spring/fall suits were selected. A series of subjective evaluation for roughness, harshness, coarseness, smoothness, warmth, bulkiness and softness were performed with 20 trained panels. The panels were selected by the test of consistency and trained for 3 weeks to enhance the reproducibility and consistency. Subjective evaluation was performed using 9 points Semantic Differential Scales with and without reference fabric. Results showed that the sensations were very similar between the results for the test of with or without reference. However the standard deviations of ratings for the with-reference were much less than that of without-reference which means the use of reference fabric can reduce the subjective error or can reduce the number of panels to test.

The Rate-of-Loading(ROL) effect of motor operated gate valves causes a decrease in the thrust delivered at a specific torque by the actuator under dynamic flow ${\Delta}$P conditions as compared to the no-flow, static conditions. This effect needs to be studied for the quantitative evaluation of motor operated gate valve operability. This study is performed to verify the validity for the application of ROL in the evaluation of operability of motor operated gate valves for the opening stroke. The ROL is assessed on the basis of in-situ test data for the opening and closing strokes. The results show that the distribution of the ROL for the operling sake has a tendency to the negative value when DP is higher than 150psid.

The variational approach for the direct evaluation of the energy difference ${\Delta}$E is studied. The method is based on the differential equation corresponding to the integral Hellmann-Feynman formula. The ${\Delta}$E is given by the expectation value of the Hermitian operator which does not involve the 1/$r_{ij}$ term. Because of its variational nature of the method, the coupling problem of the differential equations which are encountered in perturbation treatment does not occur. The method is applied to the evaluation of the electric polarizabilities of the Helium isoelectronic series atoms. The result is in good agreement with the experiment. The method is compared with the recent works of Karplus et al.

Anhidrosis refers to the condition in which the body does not respond appropriately to thermal stimuli by sweating. Sweating plays an important role in maintaining the body temperature, and its absence should not be overlooked since an elevated body temperature can cause various symptoms, even leading to death when uncontrolled. The various neurological disorders that can induce anhidrosis make a detailed neurological evaluation essential. The medication history of the patient should also be checked because anhidrosis can be caused by various drugs. The tests available for evaluating sweating include the quantitative sudomotor axon reflex sweat test, thermoregulatory sweat test, sympathetic skin response, and electrochemical skin conductance. Pathological findings can also be checked directly in a skin biopsy. This review discusses the differential diagnosis and evaluation of anhidrosis.
