The purpose of the study was to examine health status and mini nutritional assessment (MNA) according to self-esteem status of elderly in care hospital. The survey was carried out from $13^{th}$ to $31^{st}$ of September, 2014 in five care hospitals. Analysis was performed for 226 subjects. Evaluation criteria included demographics, clinical status, MNA, health-related quality of life (EQ-5D) and self-esteem. The SE I, SE II and SE III groups were divided by self-esteem scores. Data were analyzed one-way ANOVA, Duncan' multiple range test and Pearson's correlation using SPSS 15.0. Education level, religion, dental condition and medical endurance type were significantly different in all groups. Many elderly people were normal BMI ($20.94{\sim}21.67kg/m^2$). Self-esteem significantly increased in order of SE I, SE II and SE III. Mobility, usual activity and anxiety or depression were significantly different in all groups, and EQ-5D of SE II and SE III groups were significantly higher than that of SE I group. Comparison of MNA screening score in elderly patients was as follows : Score for food intake, psychological stress or acute disease, neuropsychological problems, pressure scores or skin ulcer, protein intake, mode of feeding, nutritional status and health status in SE I group were significantly lower than those of SE II and SE III groups. Mobility and drug intake of SE I group were significantly lower than those of SE III groups. Fruit and vegetable intake SE I group were significantly higher than those of SE II and SE III groups. MIS (Malnutrition Indicator Score) was significantly different among the SE I, SE II and SE III groups. We conclude that self-esteem score is positively correlated with protein intake, nutrition status, health status and MIS in elderly care hospital. To improve nutritional status of elderly in care hospitals, systematic nutrition management and self-esteem education program should be implemented.

1. Objectives : This study is a pilot study to construct of metabolic syndrome model with constitutional type. We focused on the correlation of Metabolic syndrome(MetS) and ordinary symptoms with Taeumin at 40. 2. Methods : 32 subjects who had taken health examinations and diagnosis of Sasang constitution from Oct 1, 2008 to Dec 31, 2008 at Kyung-Hee medical center were included and underwent B-mode ultrasonography for measurement of intima-media thickness of common carotid arteries. MetS was defined by the criteria of the criteria of the National Cholesterol Education Program Adult Treatment Panel III. 3. Results and Conclusions : Mean intima-media thickness of common carotid artery was higher in subjects with MetS compared with control subjects(0.56$\pm$0.12 vs 0.54$\pm$0.08mm) however. The ordinary symptoms shown to differentiate the MetS group and the control group were related to "dark urine color," "dryness of eyes," and "night sweat". Therefore, these ordinary symptoms can be said to be indicators of the Taeumin with Mets syndrome.

The relationship of maternal separation anxiety, availability of support system and child gender to initial preschool adjustment was examined. Data were collected on 72 middle-class Korean children(35 boys, 37 girls) between the ages of 31 months and 60 months who were entering preschool. Subjects were from intact families, all with non-working mothers. Mothers completed the Maternal Separation Anxiety Scale(MSAS) and indicated the number of extended family members in the home as an index of social support. Classroom teachers completed the Preschool Behavior Questionnaire (PBQ) for each child after the first 2 weeks and again after 6 weeks of school. Each child was observed by the research team during the first 2 weeks of school and again after the 6th-week using the Child Observation System (COS). Applying the COS observed behavior was classified as being in the dependent, neutral, or active mode. All instruments were culturally relevant as validated by Korean experts. Maternal Separation Anxiety was a significant predictor for girls only, accounting for 11% of initial COS variance (p=＜.05). In contrast, social support was a significant predictor for boys only, accounting for 28% of initial PBQ variance when entered after MSAS(p=.005). A significant difference between initial and 6th-week adjustment was obtained in the expected direction on the COS with behavior improving with time (t=-4.06, p=.001). Although a significant difference between initial and 6th-week PBQ adjustment was also obtained (t=-3.63, p=.001), it was not in the direction expected, problematic behavior were found to increase with time. Cultural and developmental factors help explain the findings. Given the patrilineal social system in Korea, boys are highly preferred over girls. Thus the at-home support system, comprised primarily of grandparents, may have a significant influence on school adjustment particularly of first-born sons. In contrast, since girls are viewed as fragile and vulnerable, mothers may express greater separation anxiety about girls. Finally, as would be expected, older children may be able to develop coping skills more readily than younger ones, as child adjustment on the COS significanlty improved over the 6-week period.

Changes in cell adhesion molecules are associated with infiltration and metastatic progression of cancer. Reduced expression of E-cadherin and ${\beta}-catenin$ complex in some carcinomas has been reported. The changes in the expression in oral squamous cell carcinoma (OSCC) is not fully understood and it also remains undetermined whether the expression of these adhesion molecules in metastatic lesions differs from that in the primary lesions. In the present study, therefore, we immunohistochemically examined the expression of E-cadherin and ${\beta}-catenin$ in 45 primary OSCCs and 19 metastatic lymph nodes. We compared the expression of these molecules between primary and metastatic lesions and investigated the correlation between the expression and clinicopathologic parameters. The expression of E-cadherin and ${\beta}-catenin$ was reduced in 35/45 (78.2%), 14/45 (31.2%) of primary tumors respectively, but 18/19 (94.7%) and 17/19 (89.4%) of lymph nodes showed preserved expression. The reduced expression of the E-cadherin was associated with lymph node metastasis, invasive mode and marginal status but no significant relationship was not found with ${\beta}-catenin$. In conclusion, the loss of E-cadherin and ${\beta}-catenin$ complex function is associated with progression of OSCC and suggest that the expression of this complex will be a supplementary prognostic tool.

Crush energy characteristics of graphite/epoxy square tubes are experimentally studied. Effect of the ply orientation on the peak load and the average load is investigated by applying compressive load on the top of the composite square tubes under the stroke control with crosshead speed of 0.003mm/sec and 0.3mm/sec. in addition to the experimental survey, the finite element analysis is used to estimate the peak load of the composite square tubes with [0/90]₄ and [0/±45/90]₂. The first buckling mode of the tube is superimposed to the perfect geometry and the distributed compressive load is applied on the top of the tubes. The applied compressive load that make Tsai-Wu criteria equal to one is regarded as the peak load of the tubes. The experimental data shows that the square tube with [45/-45]₄ has the highest peak load and the square tube with [60/-60]₄ has the average sustained load. The measure peak load of the composite tubes with [0/90]₄ and [0/±45/90]₂agree well with the estimated peak load using the finite element analysis.

In this paper, when a H-polarized plane wave is incident on the grating consisting of uniform resistive strips, electromagnetic scattering is analyzed using the moment of methods (MoM). The current density of each resistive strip on a grounded dielectric plane is fixed by zero at both edges. To satisfy the condition at both ends of each resistive strip, the induced surface current density is expanded in a series of cosine and sine functions. The scattered electromagnetic fields are expanded in a series of floquet mode functions. The boundary conditions are applied to obtain the unknown current coefficients. According to the variation of the involving parameters such as strip width and spacing and angle of the incident field, numerical simulations are performed by applying the Fourier-Galerkin moment method. The numerical results of the normalized reflected power for resistive strips case for zero and several resistivities are obtained.

Complete denture occlusion must be developed to function efficiently and with the least amount of trauma to the supporting tissues. For the preservation of supporting tissues, it is imperative to reduce to a minimum the functional stress induced by dentures. The magnitude of the horizontal component of functional stress contributed by various occlusal teeth forms has not been studied. This study was aimed to investigate the influence of different occlusal teeth forms on the mode of distribution of the stresses in the mandibular tissue, and the displacement of lower dentures during the variant functional movement of mandible for this study three dimensional finite element analysis was used. FEM models were created using commercial software Super Sap for IBM 32 bit computer. The model was composed of 3380 brick elements and 4346 nodes. The results were as follows. 1. The magnitude of stress was similar between two models in centric occlusion, in the case of anatomic model, the stress was concentrated on the buccal side of alveolar ridge beneath the bicuspids. 2. During the protrusive movement, the increasing of stress from the posterior to anterior part of mandible was seen in the case of anatomic model. 3. During the lateral movement, the stress of anatomic model was greater than that of nonanatomic model. 4. The stress of anatomic model was concentrated on the anterior region of residual ridge during the lateral movement. 5. In the case of anatomic model the anterior part of denture was displaced severely at the centric and lateral position, but the denture of nonanatomic model was displaced minutely at the protrusive and lateral position.

The purpose of this study is to compare calculated pollutant loadings using pollutant load unit factors and vector type coverage, and expected mean concentration(EMC) and raster type of digital elevation model(DEM). This study is also focusing on comparison of the advantages and the disadvantages of the two methods, and seeking for a method of calculation of pollutant loadings using DEM. Estimation of pollutant inputs using pollutant load unit factors has limitations in identifying seasonal variations of pollutant loadings. Seasonal changes of runoffs should be considered in the calculation of pollutant loadings from catchments into reservoirs. Evaluation of pollutant inputs using runoff-coefficient and EMC can overcome these drawbacks. Proper EMC and runoff-coefficient values for the Koeup stream catchments of the Koheung estuarine lake were drawn from review of related papers. Arc/Info was employed to establish database of spatial and attribute data of point and non-point pollutant sources and characteristics of the catchments. ArcView was used to calculate point and non-point pollutant loadings. Pollutant loads estimated with either unit factors-coverages, i.e., pollutant load unit factors and vector coverages f point sources and land use, or EMC and digital elevation mode(DEM) were compared with stream monitoring loads. We have found that some differences were shown between monitoring results and estimated loads by Unit Factors-Coverage and EMC-DEM. Monthly variations of pollutant loads evaluated with EMC-DEM were similar to those with monitoring result. The method using EMC-DEM can calculate accumulated flows and pollutant loads and can be utilized to identify stream networks. A future research on correcting the difference between vector type stream using flow direction grid and digitalizing vector type should be conducted in order to obtain more exact calculation of pollutant loadings.

Most of supervised teaming algorithms could be applied after that continuous variables are transformed to categorical ones at the preprocessing stage in order to avoid the difficulty of processing continuous variables. This preprocessing stage is called global discretization, uses the class distribution list called bins. But, when data are large and the range of the variable to be discretized is very large, many sorting and merging should be performed to produce a single bin because most of global discretization methods need a single bin. Also, if new data are added, they have to perform discretization from scratch to construct categories influenced by the data because the existing methods perform discretization in batch mode. This paper proposes a method that extracts sample points and performs discretization from these sample points in order to solve these problems. Because the approach in this paper does not require merging for producing a single bin, it is efficient when large data are needed to be discretized. In this study, an experiment using real and synthetic datasets was made to compare the proposed method with an existing one.

To design a user-adaptive web surfing system, we nay take the approach to divide the whole process into three phases; collecting user data, processing the data to construct and improve the user profile, and adapting to the user by applying the user profile. We have designed three software agents. Each privately works in each phase and they collaboratively support adaptive web surfing. They are IIA(Interactive Interface Agent), UPA(User Profile Agent), and ANA(Autonomous Navigation Agent). IIA provides the user interface, which collects data and performs mechanical navigation support. UPA processes the collected user data to build and update the user profile while user is web-surfing. ANA provides an autonomous navigation mode in which it automatically recommends web pages that are selected based on the user profile. The proposed approach and design method, through extensions and refinements, may be used to build a practical adaptive web surfing system.
