On the basis of the strain-based shear strength model developed in the previous study, a strength model was developed to predict the direct punching shear capacity and unbalanced moment-carrying capacity of interior and exterior slab-column connections. Since the connections are severely damaged by flexural cracking, punching shear was assumed to be resisted mainly by the compression zone of the slab critical section. Considering the interaction with the compressive normal stress developed by the flexural moment, the shear strength of the compression zone was derived on the basis of the material failure criteria of concrete subjected to multiple stresses. As a result, shear capacity of the critical section was defined according to the degree of flexural damage. Since the exterior slab-column connections have unsymmertical critical sections, the unbalanced moment-carrying capacity was defined according to the direction of unbalanced moment. The proposed strength model was applied to existing test specimens. The results showed that the proposed method predicted the strengths of the test specimens better than current design methods.

The purpose of this study is to investigate the shear behavior of prestressed concrete deep beams and to provide the data for development of improved design criteria. The accuracy and objectivity of the assessment process may be enhanced by the use of sophisticated nonlinear finite element analysis program. Hence, in this study, the computer program, named RCAHEST (reinforced concrete analysis in higher evaluation system technology), was used. Material nonlinearity is taken into account by comprising tensile, compressive and shear models of cracked concrete and a model of reinforcing steel. A bonded or unbonded tendon element based on the finite element method, that can represent the interaction between tendon and concrete of prestressed concrete member, is used. The proposed numerical method for the shear behavior of prestressed concrete deep beams is verified by comparing the analytical results with test data by others.

With universality of e-commerce through internet, smaller online shopping malls are increased. A Smaller online shopping mall by nature lacks an extra space to load many inventory quantities. Therefore, it is difficult to response immediately with client request with traditional inventory management method. VMI has a character that supplier can control volume of inventory according to sales of seller. This paper proposes SOHO-VMI that is applied VMI into smaller online shopping mall. Proposed SOHO-VMI supports M $\times$ N structure can interact with multiple suppliers and sellers. And it uses XML/EDI for interaction with EDI documents use to legacy system. Also, This paper proposes logistics statistic prediction algorithm can adjust production and distribution volumes to supplier considering seller's product distribution information and seasonal factor.

The purpose of this study was to evaluate the effects on maternal-fetal attachment and self efficacy for delivery using the Taekyo-oriented prenatal class. This class is for 2 hours/week for 4 weeks. The program covers the contents of fetal growth and development including their responding ability, the importance of the uterine environment, sharing the motive and purpose of pregnancy, sharing experiences about pregnancy, sharing of prejudices against delivery, training of maternal-fetal interaction, understanding delivery, relaxation breathing techniques, maternity exercises, writing letters or prayers to the baby, and declaration of loving the baby. This study took place from March 4th to June 15th, 2000, in a university hospital and community care center, and was done by with a pretest-posttest design, with 55 pregnant women who were within 32-36 weeks pregnant and who agreed to participate in this study. Data was measured twice by self-report by the Cranley's Maternal-fetal Attachment Scale(MFAS, 1981), and the Shin's(1997) Self Efficacy for Delivery Scale at the beginning and at the completion of the class. Data was analyzed by SAS. The study results were: 1. The score of maternal-fetal attachment was significantly increased after the Taekyo perspective prenatal class than before the class. (t=7.389, p=0.000) 2. The score of self efficacy for delivery was significantly increased after the Taekyo perspective prenatal class than before the class. (t=8.885, p=0.000) The above results proved that the present Taekyo perspective prenatal education program was effective in increasing maternal-infant attachment and self efficacy for delivery. Therefore, it is concluded that the existing prenatal class should include Taekyo perspective elements. However, further study is needed to compare the effects with preexisted prenatal class.

Interactions between a propeller and vortex system contained in a ship stern flow is treated theoretically. A new formulation to determine the effective velocity distributions is developed, which may be immediately applicable to the design and analysis of compound propulsors under the influence of severe vortical cross-flows around ship stern. An axisymmetric shear flow is represented by a system of ring vortices and the axial variation of the stream lines due to the action of propeller is represented by a cubic function. The strengths of ring vortices, which are varying along the stream lines, are determined by the conservation of angular momentum. Two simplified effective velocity models are proposed to confirm the theory. Sample calculations using the simplified models are made to compare with the results by other investigators.

Purpose: The purpose of this study was to investigate the effects of passive upper arm exercise on range of motion, muscle strength, and muscle spasticity in hemiplegic patients with cerebral vascular disease. Methods: A quasi-experimental design with nonequivalent control group was utilized. According to inclusion criteria, 25 patients were assigned to the control group with routine care, followed by 25 to the intervention group with passive exercise for 30 minutes per session, twice a day for 2 weeks. Eighteen patients in the intervention group and 17 in the control group completed the posttest measurement, including range of motion for upper arm joints, manual muscle test, and Modified Ashworth Scale for muscle spasticity. Results: The intervention group had a significantly improved range of motion in the shoulder and wrist joints. No interaction effect was found for the elbow joint. No significant differences were found in muscle strength or muscle spasticity between the groups. Conclusion: Results of the study indicate that passive exercise safely applied for two weeks improves range of motion in joints of the upper arm in these patients. Further study with long-term follow-up is needed to verify the role of passive exercise in preventing muscle spasticity in this population.

In general, pipes buried underground can be classified into either rigid or flexible pipe. Glass fiber reinforced thermosetting polymer plastic (GFRP) pipe can be considered as one of typical flexible pipes for which the soil-pipe structure interaction must be taked into account in the design. In this paper, we present the result of an investigation pertaining to the short-term and long-term behavior of buried GFRP pipe. The mechanical properties of the GFRP pipe produced in the domestic manufacturer are determined and the results are reported in this paper. In addition, Ring deflection is measured by the field tests and the finite element analysis. Also, the extrapolation using these techniques typically extends the trend from data gathered over a period of approximately 5,232 hours, to a prediction of the property at 50 years, which is the typical maximum extrapolation time. Therefore, it was investigated that the long-term ring deflection of GFRP pipe estimated by methods for Monod-type.

Secondary vegetation. the holistically integrated system of nature and human being, is the complicated ecosystem that is composed of natural and man-created factors. Understanding the ecological function of secondary vegetation supplies us many important informations for sustainable landscape management and ecological restoration planning. In this research, we tried to examine the shape effect of vegetation patch on early structure of populations of pine and oaks. Moreover. we also tried to clarify the ecological functions of patch edge by exploring the patch effect on germination using patch index. In addition, we present the landscape structure of man -made vegetation of our study area, and setting experimental design of research. Vegetation landscape of study area is typical human disturbed landscape mainly composed of disturbance patches. Vegetation types of graveyard and managed pine forest were controlled by periodically repeated management. However, current seedlings of pine occurred well at both vegetation types. Presence of both saplings were more controlled in managed pine forest (PDM) and graveyard (G) than those of undergrowth (PD) and forest edge (FE) with canopy trees. The number of pine seedlings increased with patch size and patch perimeter. That of oak seedlings was, however, not significantly different. Larger graveyards provided higher light availability for germination of pine seedlings. We think, however, most seedlings of both species in the large sized graveyards without shade will die more easily than that of small sized ones before rainy summer. Relationships between patch shape and germination of two woody species cannot be exactly explained enough yet in these results. More informations on spatial interaction of the total species with differently sized patches are necessary to solve the concept of patch effect on species colonization.
