본 연구는 골프스윙의 교육방법 중 현장지도를 위한 과학적 근거와 보조 자료의 필요성을 알아보기 위해 실시되었다. 따라서 숙련자인 투어프로골퍼를 대상으로 드라이버스윙의 현장지도 결과를 운동학적 관점에서 재해석하고 정밀한 분석을 통해 현장지도의 타당성과 오류를 검사하는 하나의 예를 만들어보고자 하였다. 그 결과 현장지도결과는 운동학적 기술 분석의 정성적 평가와 대상자간과 항목간에서 약간의 차이를 나타냈으며, 결국 본 연구의 5명의 대상자가 보이는 오류의 진단은 두 방법간에 약간의 차이는 있었다. 하지만 오류의 원인과 오류를 막기 위한 보상작용의 발견에 있어서 큰 차이를 보였다. 오류의 진단은 지도자의 경험에 의해 거의 대부분 가능했다. 따라서 지도자의 경험에 의한 오류 수정을 위한 피드백은 운동학적 기술 분석의 정성적 평가와 차이를 나타냈다. 결론적으로 정확한 골프스윙의 지도에 있어서는 현장지도에 의한 즉각적인 피드백과 근본적인 원인을 정확하게 판단할 수 있는 운동학적 기술 분석의 정성적 평가가 필요하다고 사료된다.

This paper presents a nondestructive evaluation approach for system identification (SID) of real railway bridges using field vibration test results. First, a multi-phase SID scheme designed on the basis of eigenvalue sensitivity concept is presented. Next, the proposed multi-phase approach is evaluated from field vibration tests on a real railway bridge (Wondongcheon bridge) located in Yangsan, Korea. On the steel girder bridge, a few natural frequencies and mode shapes are experimentally measured under the ambient vibration condition. The corresponding modal parameters are numerically calculated from a three-dimensional finite element (FE) model established for the target bridge. Eigenvalue sensitivities are analyzed for potential model-updating parameters of the FE model. Then, structural subsystems are identified phase-by-phase using the proposed model-updating procedure. Based on model-updating results, a baseline model and a nondestructive evaluation of test bridge are identified.

This paper discusses the evaluation of the safety impact of the Adaptive Cruise Control (ACC) system in Korea. To evaluate the safety impact, this paper suggests an analysis method by using the test scenario and field operational test data. The test scenario is composed to represent the main component factor of the ACC system and ACC related accident situation such as rear-end collision, lane-change, and road-curvature, etc. Also, from the field operation test data, the system's potential to increase the safety can be measured ideally. Besides, field operational testdata was used to revise the expected safety impact value as Korean road conditions. By using the proposed evaluation method, enhanced safety impact of the ACC system can be estimated scientifically.

The evaluation of field degree of consolidation on soft clays has been an important problem in geotechnical areas. Monitoring either settlements or pore water pressures has been widely applied in the filed, but occasionally they have some problems. This study addresses the suggestion and application of another method for evaluating the degree of consolidation using shear wave velocities. A research site where soft clay layers were consolidated by surcharging loads was chosen. Laboratory tests were performed to determine the relation between shear wave velocity and effective stress. Field seismic tests were conducted several times during the consolidation of the clay layers. The tests results show that the shear wave velocity increased significantly as clays consolidated. The shear wave velocities at each field stress states were derived from the laboratory results and the degree of consolidation was evaluated by comparing the shear wave velocities obtained by laboratory and field seismic methods. In most stress states, the degree of consolidation evaluated using the shear wave velocity matched well with that obtained from field settlement record, showing the potential of applying the method using shear waves in the evaluation of field degree of consolidation on soft clay deposits.

In the $21^{st}$ century of digital information society, design is changing from an analog era that focuses on logical and rational knowledge to a new paradigm of an era focused on sensible communications that can react fast. Design becomes to fulfill sensible needs; moreover, full efforts are being made in the academic research of sensibility evaluation for the conceptualization, quantization, and visualization of design sensibilities based on the measurement and evaluation of sensibility. This study provides insight into a sensibility evaluation method to understand the global user's sensibility in the fashion design field. As for research methods, first, measurement methods of physical, psychological, and physiological reactions to design sensibility were examined through written research on sensibility evaluation in both domestic and overseas research. Next, studies on sensibility during the past 15 years from 2000 to 2014 in the field of domestic fashion design were analyzed to grasp research trends in sensibility evaluation methods; subsequently, suitable sensibility evaluation methods for current fashion design were discussed. As a result of the study, it was shown that most sensibility evaluation studies in the field of domestic fashion design are based on surveys using sensibility terms. However, it requires the process of translating among different terms in different lingual cultures and within the limits of a uniformed evaluation. In this regard, recent cases of overseas design studies have been applying new methods to measure physiological reactions such as eye tracking methods combined with IT. The analysis of multilateral sensibility evaluation methods in this study have significant meaning for use as basic data to establish a planning for an evaluation scale to measure the sensibility of global consumers towards modern fashion design more quantitatively.

Beam-quality of medical linac evaluations vary by diverse factors. Because conventional beam-quality evaluation methods yield fragmentary results, a new beam-evaluation method is suggested, and its feasibility is evaluated. The PDDs (percentage depth doses) of 6 MV (Mega-voltage) and 10 MV photon, R (Range) of a 6 MeV (Mega Electron-voltage) and 9 MeV electron were measured and compared with the conventional evaluation methods, and the improved methods $PDD^{10}{_5}$, $PDD^{20}{_{10}}$, $PDD^{30}{_{20}}$, $PDD^{20}{_5}$, $PDD^{30}{_{10}}$, and $R^{70}{_{50}}$, $R^{50}{_{30}}$, $R^{70}{_{30}}$ as the magnetic field of the bending magnet was changed to +2% to -2%, and the results were compared. The comparison showed that the improved methods exhibit a higher discrimination than the conventional methods in each energy regime. $PDD^{10}{_5}$, $PDD^{30}{_{20}}$, $PDD^{30}{_{10}}$ and $R^{70}{_{50}}$, $R^{50}{_{30}}$ should be applied. These methods exhibit a higher discrimination in each energy regime than conventional beam-quality evaluation methods; therefore, they should be used for beam-quality evaluation according to the magnetic field variation.
