PURPOSES : This study was performed to investigate a feasibility of job-site use of recycled concrete aggregate exceeding 3% of absorption rate. Test variables are coarse aggregate types such as natural aggregate, job-site processed recycled aggregate, and recycled aggregate processed from the intermediate waste treatment company. METHODS : First, aggregate properties such as gradation, specific gravity and absorption rate were determined. Next a basic series of mechanical properties of concrete was tested. RESULTS : All strength test results such as compression, flexure and modulus were satisfied for the minimum requirements. Finally up to first 48 elapsed days the shrinkage strains of concretes made from both recycled aggregates (in case of volume-surface ratio of 300) appeared to be greater than 26% of the companion concretes made from natural aggregates. CONCLUSIONS : Drying shrinkage result is ascribed to greater absorption rate and specific gravity of those specimens made from recycled aggregate. This may be reduced with an addition of admixtures.

The influence of hold-down spring (HDS) on the vibration characteristics of core barrel is studied in this paper. First, the vibration characteristics experiment of core barrel was carried out with four type of different hold-down spring. These hold-down springs represent the same hold-down force under different spring stiffness and different hold-down force under the same spring stiffness. And then a new finite element method for researching the influence of hold-down spring on the vibration characteristics of core barrel was presented. This new method could consider the influence of the hold-down force and the spring stiffness at the same time. The results suggest that, the hold-down force and friction have greater influence on the vibration characteristics of core barrel than the spring stiffness, and the influence is nonlinear. The influence of the boundary condition on beam mode is greater than that on shell mode for core barrel.

Objectives : The aim of this study is to find a desirable way for acupuncture treatment of Vascular Dementia. Methods : The author reviewed several literatures related with Vascular Dementia. Based on the literatures, the author interpreted the causes and symptoms of Vascular Dementia on viewpoint of three yin and three yang. In addition, research about desirable way for acupuncture treatment was carried out. Results and Conclusions : The cause of Vascular Dementia is thought to be the functional weakness of lesser yin, the heart meridian. Also, the related-factors represent functional excess of reverting yin and greater yin, as well show functional weakness of lesser yin. Accordingly, for the acupuncture treatment of Vascular Dementia, it is necessary to tonify lesser yin. On the other hand, the activation of lesser yang is thought to be helpful.

Objectives : To analyze the contents of ≪Lingshu·Jingjin≫ and study the standard posture in context of Korean Medicine. Methods : Analyzed the terms related to the name, body region and orientation of Three Yin and Three Yang used in ≪Lingshu·Jingjin≫ to deduce the standard posture of the description. ≪Lingshu·Jingmai≫ was used as supplementary data. Results : The term "Three Yin and Three Yang" in ≪Lingshu·Jingjin≫ is used to indicate regions of the human body, and based on this, terms with orientation were used. Just like 'anatomical position', there is a standard posture in Korean Medicine, and it may seem to be similar overall, but there is a difference in posture in the upper extremity. In ≪Lingshu·Jingjin≫, Greater Yang is the dorsal region, Lesser Yang is the lateral surface region, Yang Brightness is the anterior surface region of the human body. In the body trunk, Three Yin refers to the inner parts of the human body. However, in the lower extremity, Three Yin refers to the medial surface of the legs. The name of the individual Meridian-muscle was given following the region corresponding to Three Yin and Three Yang. In ≪Lingshu·Jingjin≫, there is a basic posture that became the standard posture derived from the description. In an upright standing position, the feet face forward, the fingers naturally extended, and the back of the hand faces outward. The fact that the posture of the thumb is naturally extended is especially reflected in ≪Lingshu·Jingjin≫. This is clearly different from the "anatomical position" and as it can be the base of all areas of acupuncture, it is suggested that it be defined as the "Standard Position of Acupuncture Medicine". Conclusions : Based on our analysis, we suggest the "Standard Position of Acupuncture Medicine" as an upright standing position, with the feet facing forward, the fingers naturally extended, the back of the hand facing outward, and the thumb naturally extended.

The purpose of this experiment was to investigate the effect of the diets supplemented with lard or prilled fat ($Carolac^{(R)}$) on lactation performance, plasma constituents and ruminal characteristics of Holstein cows under a warm climate. In trial 1, 18 Holstein cows, 14 primiparas at 43 DIM and 4 multiparas at 55 DIM, were randomly assigned into six $3{\times3}$ Latin squares, in which three dietary treatments were isoproteinous but varying in energy contents and three 21 d periods. The treatments were basal diet (Control), basal diet supplemented with 2.5% lard (LD), and basal diet supplemented with 2.5% commercial Prilled fat (PF). In trial 2, three rumen canulated pregnant nonlactating Holstein cows with 550 kg average body weight were allotted into a $3{\times}3$ Latin square design with diets same as in trial 1 were fed to the cows at the level of 1.5% body weight on dry matter (DM) basis. The results indicated that the DM intake did not differ among the treatments. Milk yield and 4% FCM yield were greater (p<0.05) in PF than in Control. LD and PF resulted in greater milk fat percentage. Protein, lactose and solid contents in milk were not different among the three dietary treatments. The concentration of nonesterified fatty acids (NEFA) in plasma was significantly greater in LD and PF than that in Control. However, the concentrations of triglycerides, urea nitrogen, and cholesterol in plasma were not significantly different among the three treatments. Although the ruminal molar percentage of isobutyrate in LD and PF was greater, no significant difference was observed in ruminal pH, NH3-N concentration and VFA production among the three treatments. Diet supplemented with fat can improve milk yield and milk fat percentage without resulting in disadvantages of ruminal characteristics in cows at early lactation and under warm climate.

Purpose: The purpose of this study was to construct and test a structural equation model on resilience of breast cancer patients receiving chemotherapy. Methods: Participants were 204 patients with breast cancer who received chemotherapy treatment. They participated in a structured interview, which included social support, depression, symptom experience, self-efficacy, hope, resilience, and infection prevention behaviors. Data were analyzed using SPSS/WIN 20.0 and AMOS 18.0. Results: Lower depression (${\gamma}=-.33$, p=.020) and symptom experience (${\gamma}=-.31$, p=.012) and higher self-efficacy (${\gamma}=.32$, p=.005) and hope (${\gamma}=.48$, p=.016) were influenced by higher social support. Greater resilience was influenced by lower symptom experience (${\beta}=-.18$, p=.016), higher self-efficacy (${\beta}=.49$, p=.023), and higher hope (${\beta}=.46$, p=.012), and these predictors explained 66.7% of variance in resilience. Greater resilience (${\beta}=.54$, p =.009) made an impact on greater infection prevention behaviors. Resilience mediated the relations of symptom experience (${\beta}=-.10$ p=.013), self-efficacy (${\beta}=.27$, p=.006) and hope (${\beta}=.25$, p=.009) with infection prevention behaviors. These predictors explained 24.9% of variance in infection prevention behaviors. Conclusion: The findings of the study suggest that breast cancer patients with greater resilience who are receiving chemotherapy participate in increased infection prevention behaviors. Further research should be conducted to seek intervention strategies that improve breast cancer patients' resilience.

Purpose: The purpose of this study was to provide an effective method of exercise therapy for patients with cervicogenic headache. Methods: The subjects were divided into the following three groups according to the intervention received: cervix-stabilizing exercise (n=12, group 1), transcranial direct current stimulation (n=12, group 2), and cervix-stabilizing exercise combined with transcranial direct current stimulation (n=12, group 3). The intragroup and intergroup differences in muscle characteristics and neck disability index were compared and analyzed. Results: The comparison and analysis of the changes in muscle tone and post hoc analysis revealed statistically significant intragroup decreases in the upper trapezius and suboccipitals in groups I and III, and statistically significant intergroup differences in the upper trapezius, with greater changes in group III than in group II, and in the suboccipitals, with greater changes in groupIII than in groups Iand II. The comparison and analysis of the change in muscle stiffness and post hoc analysis revealed a statistically significanti ntra group decrease in the upper trapezius in group Iand suboccipitals in group III, and a statistically significant intergroup difference in both muscles, with greater change in group III than in group II. The comparison and analysis of change in neck disability index and post hoc analysis revealed a statistically significant intragroup decrease in all the three groups and a statistically significant intergroup difference, with greater change in group III than in groups I and II. Conclusion: The neck-stabilizing exercise and transcranial direct current stimulation were shown to be effective in decreasing the tone of the cervical muscles by stabilizing the cervical bone and improving muscle durability, and in improving the movement and limitation of joint range of motion by decreasing muscle tone and stiffness.

This study was conducted to test the significance of differences in the tactual difference thresholds and perception time for tactual direction type and finger type and radius size based on small circular button. The results show that difference threshold of vertical tactual perception is significantly greater than horizontal perception, but there are no significant differences in difference thresholds among finger types and radius sizes. Also, there are no significant differences in tactual perception time among tactual direction types, finger types, and radius types. These findings are applicable for tactual user interface design.
