In addition to our previous study on the diseases and symptoms described in Juan Wooden Slips(居延漢簡), here we focused on therapeutics of Juan Wooden Slips, including herbal medicines, acupuncture, and moxibution. In Juan Wooden Slips, there are 36 species of medicinal herbs and 17 herbal prescriptions. Among the medicinal herbs, 75% of herbs were also used in Shanghanzabing-lun(傷寒雜病論). In terms of efficacy and therapeutic range of the medicinal herbs and prescriptions, Juan Wooden Slips is very similar to Shanghanzabing-lun. In addition, acupuncture were used as a combined with moxibution or herbal remedies similarly to Shanghanzabing-lun. Thus, we suggest that the medical thoughts and technologies shown in Juan Wooden Slips might influence on the establishment of Shanghanzabing-lun.

The occurrence of cycle slips is a major limiting factor to attain high precision positioning and navigation results with GPS. Cycle slips must be correctly repaired at the data processing stage. In this study, the technique to find cycle slips in the processing of data collected with Trimble 4700 GPS receivers is suggested. The use of Kalman filtering techniques is used in an attempt to reduce the effect of the noise in the different quantities involved and to improve the accuracy in cycle slip correction.

More than 30,000 Wooden Slips were excavated in the Juyan region in 1930s and 1970s. These slips recorded military actions of Juyan Frontier Fortress during Han dynasty, which is about BC 100 ~ AD 30. On the slips, there are many disease names and symptoms mentioned. We focused on a certain disease name, namely, Shnaghan(傷寒; injured by cold), which is the main subject of Shangha-lun(傷寒論). Looking closely into these Juan Wooden Slips, we found many articles recording Shanghan, including related diseases and symptoms, such as Shanghan(傷汗; injured by sweat), headache, fever and chills, immobilization of limbs, unacceptance of foods. And there are another Shanghan-related symptoms, such as inflation of upper-abdomen(心腹支滿), pain of upper abdomen(心腹痛), strain of both armpits(兩胠葥急), inflation of chest(胸脇支滿), tightness and fear in the chest(煩滿). Although they have no direct relationship with Shanghan, there are many symptoms, including the external wounds of waist, finger, thigh, back, breast and head, abscess of leg and elbow, sore throat, itching, leucorrhea, powerlessness of hands and legs(手足癃), visceral injury(傷臟), tinnitus, cold, warm and heat. Because the Wooden Slips are very short, with some characters even missing, we can not confirm the detail of the disease and symptoms. In addition, we will report about the herbal medicines and other treatments, which are recorded on the slips, by further research.

To simulate an actual slip to measure floor slipperiness, slip resistance testers simulate slip in only forward direction because forward slip in the landing phase was found to be the most important factor for loss of balance. Backward slip in the take off phase was possible but was excluded in the friction test protocol because it was not dangerous. However, backward slip was tested in the friction test protocol without any theoretical background of the significance in generating dangerous slips and falls and was proven to be as good as forward slip in measuring floor slipperiness. Therefore, this study was designed to investigate the significance of backward slip in generating dangerous slips and falls with different combinations of floor and shoe sole. The results showed different tendency of backward slip in take off phase being significant in generating dangerous slips and falls because backward slip in the takeoff phase affected gait pattern disturbances seriously. resulted in dangerous falls. Fast toe velocity increased the severity of backward slip and confirmed the significance of backward slip in generating dangerous slips and falls. As a result, this study recommends the utilization of backward slip in the measurement of floor slipperiness.

태안 해역의 마도1호선에서는 해양에서 처음으로 총 57점의 죽찰이 출수되었다. 죽찰의 수량이 많아 세척과정 중 유물 상태를 관찰하여 부후정도에 따라 그룹화한 후 순차처리하였다. 또한 치수안정화과정에서 부후가 많이 진행된 죽찰은 PEG 4000, 부후가 많이 진행되지 않은 죽찰은 PEG 2000으로 처리하였다. 진공동결건조 후 PEG 4000으로 처리한 죽찰은 공업용 열풍기를 이용해 표면처리를 실시하였는데 일부는 재색이 많이 어두워졌다. 이를 보완하고자 스팀다리미를 이용하여 표면처리를 실시하였다. 스팀다리미로 표면처리한 죽찰은 재색을 잘 유지하였다. 처리 완료 후 일부 죽찰은 두께에 비해 길이가 긴 편이라 처리 후 무게를 지지해주는 견고성이 많이 떨어졌다. 이런 경우 유물의 이동과정이나 전시 중 유물이 더 손상되는 결과를 가져올 수 있어서 견고성을 더 높여주며 형태유지를 할 수 있는 방법을 찾고자 하였다. 따라서 묵서가 없는 면인 최외층에 100% PEG 2000 용액을 접착제로 사용하여 레이온지를 배접하는 방식을 취하였다. 이는 견고성을 높이면서 형태유지에도 좋은 효과를 보였다.

Deformation of single crystals was studied using finite element analysis to investigate the orientation dependence of plastic deformation observed in NiAl single crystals. Investigation of mechanical properties of single crystals is closely related with the understanding of deformation processes in single crystals. Orientation dependence of material behavior in NiAl single crystals was studied by rotating loading directions from 'hard' orientation. The maximum nominal compressed stress in NiAl single crystals was ranged in a quite wide scope depending on the misalignment from 'hard' orientation. As the compressed axis set closer to 'hard' orientation, the maximum nominal compressed stress rapidly increased and made <100> slips difficult to activate. Therefore, non-<100> slips will be activated instead of <100> slips for 'hard' orientation.

Deformations of single crystals were studied using finite element analysis to investigate the localized modes and the orientation dependence of plastic deformation observed in single crystals. Investigation of mechanical properties of single crystals is closely related with the understanding of deformation processes in single crystals. Localized bands such as shear and kink were studied and the material and geometric characteristics that influence the formation of such localized bands were investigated. Orientation dependence of material behavior in NiAl single crystals was studied by rotating slip directions from 'hard' orientation. The maximum nominal compressed stress in NiAl single crystals was widely ranged depending on the misalignment from 'hard' orientation. As the compression axis was set closer to 'hard' orientation, the maximum nominal compressed stress was rapidly increased and made <100> slips difficult to activate. Therefore, non-<100> slips will be activated instead of <100> slips for 'hard' orientation.

The $\{10\bar{1}2\}$ twinning characteristics, such as active twin variants, volume fraction of twins with strain, twin morphology, twin texture and angle relationship between twins, were dependent on the activation mode (i.e., tension parallel to the caxis or compression perpendicular to the c-axis). The selection criterion of active twin variants was governed by the Schmid law. This activation of selected twin variants depending on the activation mode consequently caused a totally different plastic deformation behavior in two activation modes. The differences in the deformation characteristics, such as flow stress and work hardening rate, between both activation modes were explained in relation with activation stresses for slips and twinning, relative activities of twinning and slips during plastic deformation, grain refining effect by twin boundaries (Hall-Petch effect), and twinning-induced change in activities of slips.

For Barrier-Free certification, the floor and ground surfaces must be finished with materials that are not slippery, flat, and have low-impact in fallis. However, the BF Certification Act does not provide specific methods to meet these regulations. In performance-based design, the responsibility of proving the performance rests with the building owner and architect, so quantitative evaluation indexes are needed to select suitable materials. Furthermore, changes in performance after completion should be checked periodically in 'As-Is' conditions. There are various methods for slips, trips and falls risk assessment, causing confusion for users. In this study, the results of previous studies on the evaluation methods of slips, trips and falls were considered closely, and each quantitative evaluation index that can be used in the new construction and maintenance phase was presented.
