Purposes: To identify the predictors of calcium intake behavior and examine the relationships among bone mineral density, osteoporosis knowledge, osteoporosis health belief, osteoporosis self efficacy and calcium intake behavior of postmenopausal osteoporosis patients. Methods: The subjects consisted of 94 patients. The measurement tools were osteoporosis knowledge test, osteoporosis health belief scale, osteoporosis self-efficacy and calcium intake frequency questionnaire. The data were analyzed using the SPSS WIN 11.0 program. Results: The bone mineral density of the lumbar were $0.75g/cm^2$, T-score -2.67 and the femur neck were $0.67g/cm^2$, T-score -2.30. There was statistically a significant correlation between calcium intake behavior and health motivation (r=0.449, p=0.000) among the osteoporosis health belief. In hierarchial multiple regression analysis, current spouse(12.8%) and health motivation(19.9%) of the osteoporosis health belief explained the 32.7% of variance in calcium intake behavior. Conclusion: Nursing intervention should be developed for increasing the calcium intake behavior through promoting health motivation for the postmenopausal osteoporosis women having no spouse currently.

This study explored the development of wood furniture made of aged Castanea crenata Sieb. et Zucc, which has been largely planted in the southern area since 1960s and has hardly been used as furniture materials. First, the physical properties of the chestnut wood including specific gravity, stiffness, and shrinkage were compared with Zelkova serrata, Acer palmatum Thunb., Fagus crenata var. multinevis, Quercus, Tagayasan, Prunus serrulata var. spontanea, Juglans sinenis, Pteronrpus santalinus, Diospyros ebenum, and Fraxinus rhynchophylla, which have largely been used in manufacturing furniture. The chestnut wood had appropliate physical properties for wood furniture like other furniture woods. A piece of small table 50 cm in width, 50 cm in length and 60 cm in height by the chestnut tree was created for a current interior space. Since the diameter of the chestnut tree planted since 1960s is below around 30 cm, the top plate of the table had to be put together by an end-joint technique using a small strip. Finally, it is expected that this study will create a greate motivation for furniture designers, furniture studios and furniture companies in Korea to use the woods from the aged chestnut tree in developing furniture in the future.

This paper deals with the applicability of long-gauge deformation fiber optic sensors (FOS) to prestressed concrete structures. A main motivation is the desire to monitor the deflection of the railway bridges without intervenes of the signal intensity fluctuations. A 25 m long, 1.8 m deep PSC girder was fabricated compositely with 22 cm thick reinforced concrete deck. Two pairs of 3 m long-gauge sensors are attached to the prestressed concrete girder with parallel topology. Using the relationship between curvature and vortical deflection and the quadratic regression of curvatures at the discrete point, it is possible to extrapolate the deflection curve of the girder. The estimated deflection based on the developed method is compared with the results using conventional strain gauges and LVDTS. It has been demonstrated that the proposed instrumentation technique is capable of estimating the vertical deflection and neutral axis position of the prestressed concrete girder up to weak nonlinear region.

Integrated Project Delivery (IPD) as a delivery method fully capitalizes on an integrated project team that takes advantage of the knowledge of all team members to maximize project outcomes. IPD is currently the highest form of collaboration available because all three core project stakeholders, owner, designer and contractor, are aligned to the same purpose. Compared with traditional project delivery approaches such as Design-Bid-Build (DBB), Design-Build (DB), and CM at-Risk, IPD is distinguished in that it eliminates the adversarial nature of the business by encouraging transparency, open communication, honesty and collaboration among all project stakeholders. The team appropriately shares the project risk and reward. Sharing reward is easy, while it is hard to fairly share a failure. So the compensation structure and the contingency in IPD are very different from those in traditional delivery methods and they are expected to encourage motivation, inspiration and creativity of all project stakeholders to achieve project success. This paper investigates the compensation structure in IPD and provides a method to determine the proper level of contingency allocation to reduce the risk of cost overrun. It also proposes a method in which contingency could be used as a functional monetary incentive when established to produce the desired level of collaboration in IPD. Based on the compensation structure scenario discovered, a probabilistic contingency calculation model was created by evaluating the random nature of changes and various risk drivers. The model can be used by the IPD team to forecast the probability of the cost overrun and equip the IPD team with confidence to really enjoy the benefits of collaborative team work.

The aim of this paper is to present a new sustainable ternary and quaternary binder by partially replacing ordinary Portland cement (OPC) with different percentages of supplementary cementitious materials. The motivation is to reduce our dependency on OPC to reduce CO₂ emission and carbon foot print. As the main substitute for the OPC, siliceous fly ash was used. Moreover, silica fume and nanosilica were also used. During examinations the main mechanical parameters of concrete composites, i.e., compressive strength (f_cm) and splitting tensile strength (f_ctm) were assed. The microstructure of these materials was also analysed. It was found that the concrete incorporating pozzolanic materials is characterized by a well-developed structure and has high values of mechanical parameters. The quaternary concrete containing: 80% OPC, 5% FA, 10% SF, and 5% nS have shown the best results in terms of good strength parameters as well as the most favourable microstructure, whereas the worst mechanical parameters with microstructure containing microcracks at phase interfaces were characterized by concrete with more content of FA additive in the concrete mix, i.e., 15%. Nevertheless, all concretes made on quaternary binders had better parameters than the reference one. It can be stated that sustainable concrete incorporating pozzolanic materials could be good substitute of ordinary concretes.

The purpose of this study was to investigate the health status and food habits of male college students in Seoul according to drinking habits. In order to identify risk factors, health surveys were conducted from October 2013 to December 2013. Average height, weight, and BMI of subjects were $175.47{\pm}5.27cm$, $67.93{\pm}9.28kg$, and $22.04{\pm}2.67kg/m^2$, respectively. Weight and BMI were higher in the non-drinking groups compared to the drinking groups (p<0.05). Frequency of drinking was 2~3 times per month, and 52.4% of subjects started drinking when starting university. The motivation to start drinking was cited as "From necessity". Reason for drinking was "Social relations". The favorite kind of drink was beer. Rate of taking supplements was 24.4% of the subjects. Vitamin preparations were highest in drinking groups and non-drinking groups (p<0.05). The reasons for skipping meal were "too busy" in the drinking groups, and "oversleep" in the non-drinking groups (p<0.05). The preference for snacking in drinking groups were milk, milk products, and fast food, with the highest being listed first. The non-drinking groups preferred carbonated drinks and ice cream. The drinking groups need more education about their drinking habits. Drinking groups also need an increased intake of vegetables and fruits.
