The purpose of this study was to investigate effects of web-based nutrition counseling on nutrient intake and blood glucose in type ll diabetic Patients. Forty type II diabetic patients, twenty one of them were diabetic patients without complication (Ncx-DM) and nineteen of them were diabetic patients with complication (Cx-DM), participated in a web-based nutrition counseling program. At the first nutrition counseling, the patients were counselled through interview and then follow up nutrition counseling was accomplished four times during eight weeks through tile web-based internet program. Various markers of disease risk including anthropometric indices, nutrient intake and blood glucose were measured before and after the nutrition counseling. After the nutrition counseling, body mass index and waist circumference decreased in both group but did not change significantly. Fasting blood glucose significantly decreased from 153.9 mg/dL to 139.0 mg/dL (p<0.05) in NCX-DM and from 178.2 mg/dL to 128.5 mg/dL (p<0.01) in Cx-DM after the nutrition counseling. Glycosylated hemoglobin level decreased from $9.3\%$ to $8,7\%$ in Ncx-DM and significantly decreased from $9.7\%$ to $7.8\%$ (p<0.01) in Cx-DM after the nutrition counseling. In addition, total cholesterol and LDL-cholesterol level significantly decreased in both group (P<0,05) after the nutrition counseling. Energy intake decreased significantly in Ncx-DM (P<0.05) and Cx-DM (p<0.01). Although the nutrient intake did not change significantly, the nutrient intake was improved after the nutrition counseling. Therefore, this study shows that the web-based nutrition counseling is effective in improving energy and nutrient intake and influences positively in blood glucose and serum lipids of the patients. In addition, these results indicate that the internet presents us with potential as a new medium for nutrition counseling in informationized society.

Purpose: This study was conducted to evaluate the effects of integrated palliative care intervention on quality of life in terminally ill patients. Methods: A comprehensive literature search was performed via PubMed, Cochrane Library CENTRAL, LWW (Ovid), CINAHL and several Korean databases. The main search strategy was to combine terms indicating palliative care intervention, presence of terminal illness and study design. Methodological quality was assessed using Cochrane's Risk of Bias for randomized studies and Risk of Bias Assessment tool for non-randomized studies. Data were analyzed by the Stata 10 program. Results: Eight clinical trials met the inclusion criteria with a total of 356 participants. Integrated palliative care interventions were administered for a mean of 6.5 weeks, 5.6 sessions and an average of 47.8 minutes per session. Effect sizes were heterogeneous, and subgroup analysis was done. Integrated palliative care interventions had a significant effect on quality of life (ES=1.83, P=0.018, $l^2=92%$), spiritual well-being (ES=0.78, P=0.040, $l^2=0$), depression (ES=0.86, P<0.001, $l^2=32$) and anxiety (ES=0.69, P=0.041, $l^2=71.1$). But integrated palliative care interventions had no significant effect on pain (ES=0.365, P=0.230, $l^2=69.8$). Conclusion: Results support findings that integrated palliative care interventions were helpful in lessening depression and anxiety and improving quality of life and spiritual well-being, however, the interventions did not assist pain management in terminal cancer patients. These findings suggest that various integrated palliative care interventions can assist terminal cancer patients with better quality of life in the socio-psycho-spiritual dimension.

Background: Self-gravity acupressure (SGA), which complements the limitations of conventional manual therapies, is expected to have a positive effect on mood, closely related to reduction in stress. Purpose: This study aims to evaluate changes in mood states by SGA and to discuss its effects on stress relief and immunity. Methods: For 118 subjects (21 males and 97 females) who experienced the SGA program for 75 minutes, their mood states were assessed before and after the SGA session on 5 scales (0-4 points) using K-POMS consisting a total of 65 items grouped in six factors. For calculating the total mood disturbance score (iTMDs), the scores of the items in the only positive mood factor 'vigor-comfort' were reversed to have iTMDS increase the degree of the positive correlation with negative mood states. Results: The iTMDS decreased by 11.50% from 1.09±0.54 before SGA to 0.63±0.40 after SGA (p<0.001). The average score of the only positive factor 'vigor-comfort' increased by 10.78%, from 1.93±1.17 before SGA to 2.38±1.31 after SGA (p<0.001). On the other hand, the factor 'fatigue-inertia' of the 5 negative factors decreased most significantly in its average score by 16.73%, from 1.19±1.24 before SGA to 0.40±0.58 after SGA (p<0.001). The remaining 4 negative factors (depressed state, anxiety-fear, anger-hostility, and uncertainty-helplessness) decreased by within the range of 7.75% to 11.33% (p<0.001). Conclusions: Changes in K-POMS scores observed in this study indicate that the SGA program improves significantly mood. Since a mood state is closely related to stress and immunity, SGA is expected to have effects on stress relief and immunity enhancement (p<0.001). Continued studies are suggested to further validate the present results and to enhance the clinical utility, which include physiological signal measurements and clinical pathological examinations to test the effetcs of SGA on stress management and immunity enhancement.

With the recent industrial developments and economic development nationally, there has been a rapidly increasing demand for the use of underground space as locations for establishing social infrastructure and various convenience facilities. In this study, a mist-control system was developed to reduce the generation of dust in underground blasting. To enhance the dust-reduction effect, a guiding device was developed which is capable of adjusting the direction of the spray toward's the blasting face of mine or tunnel. A numerical analysis was performed by using the AUTODYN software, and results were compared with those published in basic experiments. To verify the mist-diffusion effect according to the position of explosives in a water bag, numerical analyses were conducted for the following cases: Explosives were set in the middle, and in the bottom of the water bag. The optimum condition was external detonation and center charge. The mist particle size from the result was suitable for the reduction of dust after blasting in underground mine and tunnel.

In this study, material nonlinear finite element program is developed to analyze reinforced concrete shell of arbitrary geometry considering tension stiffening effects. This study is capable of tracing the load-deformation response and crack propagation, as well as determining the internal concrete and steel stresses through the elastic, inelastic and ultimate ranges in one continuous computer analysis. The cracked shear retention factor is introduced to estimate the effective shear modulus including aggregate interlock and dowel action. The concrete is assumed to be brittle in tension and elasto-plastic in compression. The Drucker-Prager yield criterion and the associated flow rule are adopted to govern the plastic behavior of the concrete. The reinforcing bars are considered as a steel layer of equivalent thickness. A layered isoparametric flat finite element considering the coupling effect between the in-plane and the bending action was developed. Mindlin plate theory taking account of transverse shear deformation was used. An incremental tangential stiffness method is used to obtain a numerical solution. Numerical examples about reinforced concrete shell are presented. Validity of this method is studied by comparing with the experimential results of Hedgren and the numerical analysis of Lin.

Generally, teaching in computer Labs is more difficult than teaching in a normal class for teachers to give students systematic learning. One of the reasons is that the students who participate in the class tend to use the programs that are not related to the practice included in the curriculum. Therefore, the students cannot focus on the subjects that they should do. To solve this problem, there are many kinds of systems that can control the students' computers. However, they cannot help teachers to manage the students and computers due to the inconvenience of usage and the lack of functions. In this study, we analyzed the problems in the computer-practice classwork and designed a new system to support that the students can participate in the computer classes with more attention. In addition, it is offered that the computer teachers can manage the classes and the students more efficiently with this new system. For these purposes, the effects mentioned were approved before in the real lab situations. Experimental results showed that the proposed system can improve the rate of the students attention, leading them to get better grades on the achievement test.

In introducing memory methods in various educational fields, programs in a mobile environment can be used for the purpose of increasing accessibility and enhancing the effectiveness of education. It is much easier to remember words with meaning than to remember numerical information such as years. From the standpoint of increasing the educational effect, the part that needs to be supplemented with the help of the application can be said to be numerical information. Most studies related to conventional numerical memory have focused on the form that helps memory by imaging numbers. In the paper on memory-based meta-record algorithms in the mobile environment, the application developed in the previous study attempts to supplement this by discovering and simply modifying the user's mistakes in the entered numerical information. In this study, we aim to increase the memory rate by constructing metadata based on personalized log information and correcting mistakes. To do this, applications suitable for the mobile environment are developed, a structure of meta-record data is proposed, and meta-record application algorithms are implemented and evaluated.

In this study, the structural performance of nuclear power plant containment buildings, which are made of steel fiber reinforced concrete(SFRC) and subject to aircraft crash, is examined by finite element analyses. The applied loads by aircraft crash against the buildings are modeled using Riera impact load function and by the varying aircraft contact area with respect to time. CSCM concrete model in LS-DYNA is employed to model SFRC. The parameters for the material model are determined from SFRC strength prediction models. Based on the volume ratio of steel fiber in SFRC, the structural performance of nuclear containment buildings subject to aircraft crash are analysed using a commercial finite element analysis program LS-DYNA. The safety assessments of the buildings subject to the crash are discussed and the effectiveness of SFRC for nuclear power plant containment building on the increase of aircraft crash resistance is also evaluated.
