This paper investigate to test the validity of the basic assumptions of strategic trading models with the broker and informed trader using daily closing data of KOSPI 200 stock index futures for the year 2001-2003. Major results are summarized as follows: (i) For these years, while foreign investors and brokerage companies traded for the directions consistent with the model, brokerage companies and individual investors traded for inconsistent directions. (ii) Cross correlation function (CCF) analysis shows no systematic dependency in the trading between all three participants(foreign investor, brokerage companies and individual investors) for these years. (iii) Chi-square validity test for the 30 days of the largest unexpected trading volume shows some systematic dependency in the trading between three participants for these years. Finally, some limitations of this paper and direction for further research were suggested.

The main objective of this study is to investigate the effect of metal z-pinning on the failure behavior of cocured composite single-lap joints. Three different pin diameters (0.3, 0.5, and 0.7 mm) and three pin areal densities (0.5, 2.0, and 4.0%) were examined. The specimens were fabricated by T700-12K-31E#2510 unidirectional prepreg from Toray. Stainless steel pins were used for z-pinning. Test results showed that except one case with extremely low pin density of 0.5%, all other z-pinned joints exhibited lower initial crack stresses than those of the unpinned joint. However the ultimate strength of the z-pinned joint increased up to 45% at most. Furthermore, even after the complete failure of the joint, the z-pins sustained the carried load to a certain degree experiencing large deformation and provided the stable fracture behavior for the composite joint.

Purpose: The purpose of this study was to identify influencing factors on rehabilitation adherence in stroke patients. Methods: This study was a descriptive survey. A structured questionnaire was used for face-to-face interviews with a convenient sample of 192 subjects, who were admitted in 5 rehabilitation hospitals located in G metropolitan city. Results: The score of rehabilitation motivation in the subjects was a mean of $2.04{\pm}0.35$, self-efficacy $6.22{\pm}2.32$, family support $3.40{\pm}0.82$ and rehabilitation adherence $3.08{\pm}0.41$. The rehabilitation adherence was a statistically significant difference according to the education level (F= 3.40, p= .035), marital status (F= 4.04, p= .019), number of personal insurance policies (K= 9.80, p= .020), location of paresis (F= 2.72, p= .046), and status of current smoking (M = 657.00, p= .001). There was significant correlation among degree of rehabilitation adherence, rehabilitation motivation (r= .30, p< .001), self-efficacy (r= .14, p= .046) and family support (r= .18, p= .011). Rehabilitation motivation (${\beta}=0.19$, p= .007), self-efficacy (${\beta}=0.14$, p= .035), marital status (${\beta}=0.14$, p= .038), number of personal insurance policies (${\beta}=-0.15$, p= .045) and location of paresis(${\beta}=-0.15$, p= .028) were identified as significant predictors. This model explained 22.6% of variance in rehabilitation adherence (F= 5.92, p< .001). Conclusion: There is a need to develop an effective intervention for rehabilitation adherence improvement considering the identified variables in this study.

A theoretical study was performed to investigate the behavioral chracteristics and shear strength of fiber reinforced concrete slender beams. In the fiber reinforced concrete beam, the shear force applied to a cross section of the beam was resisted by both compressive zone and tensile zone. The shear capacity of the compressive zone was defined addressing the interaction with the normal stresses developed by the flexural moment in the cross section. The shear capacity of the tensile zone was defined addressing the post-cracking tensile strength of fiber reinforced concrete. Since the magnitude and distribution of the normal stresses vary according to the flexural deformation of the beam, the shear capacity of the beam was defined as a function of the flexural deformation of the beam. The shear strength of the beam and the location of the critical section were determined at the intersection between the shear capacity and shear demand curves. The proposed method was developed as a unified shear design method which is applicable to conventional reinforced concrete as well as fiber reinforced concrete.

An experimental study was conducted to investigate the effectiveness of transverse reinforcement in reinforced concrete tied columns subjected to monotonically increasing axial compression. Eighteen large-scale columns(260$\times$260$\times$1200 mm) were tested. Effects of main variables such as the concrete compressive strength, the tie configuration, the transverse reinforcement ratio, the tie spacing, and the spatting of the concrete cover were considered. High-strength concrete columns under concentric axial loads show extremely brittle behavior unless the columns are confined with transverse reinforcement that can provide sufficiently high lateral confinement pressure There is a consistent decrease in deformability of column specimen with increasing concrete strength. Test results were compared with the previous confinement model such as modified Kent-Park, Sheikh-Uzumeri, Mander, and Saatcioglu-Razvi model. The comparison indicates that many previous models for confined concrete overestimate or underestimate the ductility of confined concrete.
