In this paper, a compact, light-weight, universal, spherical 3-degree-of-freedom, parallel-structured manual controller with high reflecting-force capability is implemented. First, the position analysis, kinematic modeling and analysis, force reflecting transformation, and applied force control schemes for a parallel structured 3 degree-of-freedom spherical system have been described. Then, a brief description of the system integration, its actual implementation hardware, and its preliminary analysis results are presented. The implemented parallel 3 degree-of-freedom spherical module is equipped with high gear-ratio reducers, and the friction due to the reducers is minimized by employing a force control algorithm, which results in a "power steering" effect for enhanced smoothness and transparency (for compactness and reduced weight).d weight).

The purpose of this study to compare the muscle performances (peak torque (PT), relative strength (RS), average power (AP), and total work (TW)) between taping group and non-taping group after 1 hour extensive exercise. Twenty healthy male subjects were evaluated in this study. Each subject was divided with taping(n=10) and non-taping group (n=10) randomly. Muscle performances were measured at 60 degree/sec and 180 degree/sec on the Cybex 770. The PT, RS, AP, and TW were measured before and after 1 hour extensive exercise. The results showed that taping group demonstrated significantly higher PT, RS, AP, and TW during ankle dorsiflexion and plantar flexion at 60 degree/sec than those of non-taping group, except for total work during ankle plantar flexion. At the 180 degree/sec, PT and RS was significantly higher during ankle dorsiflexion and plantar flexion in taping group than in non-taping group. This results suggest that lower leg taping could be useful to maintain muscle performances during sport activities.

This study was carried out for the stability analysis of earth dam by the variation of compaction density. The test samples were taken from five kinds of soil used for banking material and the degree of compaction for this samples were chosen 100, 95, 90, 85, and 80 percent. The stability problems were analysed by the settlement and camber( extra banking) of dam, strength parameter and dam slope, and coefficient of permeability and seapage flow through dam body. The results of the stability analysis of earth dam are as follows. 1. The more the fine particle increases and lower the compaction degree becomes, the lower the preconsolidation load becomes but the compression index becomes higher. 2. Sixty to eighty percent of settlement of dam occurs during the construction period and the settlement ratio after completion of dam is inversly proportional to the degree of compaction. 3. The camber of dam has heigher value in condition that it has more fine particle(N) and heigher dam height(H) with the relation of H= e(aN-bH-e). 4. The cohesion(C) decreases in proportion to compaction degree(D) and fine particle(N) with the relation of C= aD+ bN-c, but the internal friction angle is almost constant regardless of change of degree of compaction. 5. In fine soil, strength parameter from triaxial compression test is smaller than that from direct shear test but, they are almost same in coarse soil regardless of the test method. 6. The safety factor of the dam slope generally decreases in proportion to cohesion and degree of compaction but, in case of coarse soil, it is less related to the degree of compaction and is mainly afected by internal friction angle. 7. Soil permeability(K) decreases by the increases of the degree of compaction and fine particle with relation of K=e(a-bl)-cN) 8. The more compaction thickness is, the less vertical permeability (Kv) is but the more h6rzontal permeability (KH) is, and ratio of Kv versus KH is largest in range from 85 to 90 percent of degree of corn paction. 9. With the compaction more than 85 percent and coefficient of permeability less than ${\alpha}$X 10-$^3$cm/sec, the earth dam is generally safe from the piping action.

This study aimed to evaluate the marginal microleakage of Class V cavities of All-bond 2 (Wet - bonding system), Gluma (Adhesion of resin to exposed collagen fibers), and Scotchbond Multi-purpose(Mild Etching System). Hundred extracted human teeth divided into a control and three experimental groups consisting of eight teeth. The experimental group was further subdivided into All- bond2, Gluma and Scotchbond MP groups, Vitrebond served as the control. The positive control group consisted of specimens filled with resin and with no etching, primer and bonding procesure. Polished specimens underwent temperature changed from $5^{\circ}C$ to $55^{\circ}C$ a thousand times. After thermocycling, speciemens were placed in 2 % methylene blue dye solution for 24 hours in an incubator set at $37^{\circ}C$. The teeth were sectioned buccolingually and the degree of dye penetration was observed with a stereomicroscoped(*20). The following results were obtained. 1. Both the control and the experimental group showed a lower degree of dye penetration on enamel than on dentin margins(p<0.05) 2. Gluma exhibited a statistically significant lower degree of dye penetration than All-bond 2 on enamel margins(p<0.05) Scotchbond MP also exhibited a lower degree of dye penetration than All-bone 2 but was no statistically significant. Gluma and Scotchbond MP exhibited a similar degree of dye penetration. 3. The degree of dye penetration of All-bond 2, Gluma and Scotch bond MP showed no statistically singnificance on enamel margins but was significantly lower than in the control using Vitrebond. 4. All-bond 2 exhibited a statistically significant lower degree of dye penetration than Gluma on dentin margins. All- bond 2 and Scotchbond MP showed a similar degree of dye penetration. 5. The degree of dye penetration of All-bond 2, Gluma and Scotchbond MP showed no statistically significance on dentin margins. There was neither a statistical significance with the control.

The aim of this thesis is to examine the effect of the diuretics in the Sasang constitutional medicine those are not categorized to the diuretic in the established herbal medicine by the way of measuring the change of body edema and the quantity of body moisture through the inbody test, along with the urine volume taken for 24 hours 1. We medicated the diuretic suggested by the DongyiSuseBowon東醫壽世保元 into the tested group and measured the change of the urine volume, the quantity of body moisture and the degree of body edema. The results are the followings below. 1) Soeumin The change in the urine volume and body moisture showed no responsibility, but the degree of body edema decreased with the responsibility. 2) Soyangin All of the degree of body edema and the urine volume, and body moisture showed decrease. 3) Taeumin The urine volume and body moisture increased but showed no responsibility. Also the degree of body edema decreased within the normal limit which can not be accepted. 4) The medicine of the Sasang Constitutional Medicine can not be simply thought to be the diuretic, but it has the function that excretes the moisture which functions negatively in the body and causes edema, as well as the function of the adjustment of metabolism that preserves the normal amount of moisture. This is the good example which is the concept of the adjustment therapy suggested by The Sasang Constitutional Medicine 2. Through the results above, we can find that the diuretic suggested by The Sasang Constitutional Medicine functions in the way that is differently explained by the herbal medicine.

Background: This study was to survey the effect of the degree of spiritual nursing care performance on the spiritual nursing care ability of the nursing students Methods: The researcher sampled 130 nursing students for a questionnaire survey conducted from September 17 until September 27, 2018. The data of analysis used SPSS 23.0 program. Results: The spiritual nursing care ability was $4.4{\pm}0.8$(total score 6) and the degree of spiritual nursing care performance was $2.9{\pm}1.8$(total score 4). The spiritual nursing care ability differed significantly depending on religion(F=7.570, p<.001), the level of spiritual nursing knowledge(F=19.873, p<.001), education type(F=14.626, p<.001), necessity of hospice(t=2.280, p=.024). The degree of spiritual nursing care performance differed significantly depending on spiritual nursing education time(F=2.932, p=.036). The correlation of two variable was statistically significant difference(r=.206, p=.019). The influencing factors on the spiritual nursing care ability was religion, the level of spiritual nursing knowledge, education type, dying experience($R^2=0.378$, Adj $R^2=0.353$), the degree of spiritual nursing care performance was spiritual nursing education time($R^2=0.065$, Adj $R^2=0.043$). Conclusion: These results show that nursing students are not able to perform spiritual nursing care properly to subjects who need spiritual nursing care. Therefore, it is necessary to develope programs to meet the spiritual nursing care needs of nursing students and to provide practical education in accordance with the program by cooperating with the nursing education staff, clergy and clinical nurse etc. And spiritual nursing care should be taught as a required subjects in the curriculum.
