In order to solve the problem of calculating the reasonable completed bridge state of a self-anchored hybrid cable-stayed suspension bridge (SA-HCSB), this paper proposes an analytical method. This method simplifies the main beam into a continuous beam with multi-point rigid supports and solves the support reaction forces. According to the segmented catenary theory, it simultaneously solves the horizontal forces of the main span main cables and the stay cables and iteratively calculates the equilibrium force system on the main beam in the collaborative system bridge state while completing the shape finding of the main span main cable and stay cables. Then, the horizontal forces of the side span main cables and stay cables are obtained based on the balance of horizontal forces on the bridge towers, and the shape finding of the side spans are completed according to the segmented catenary theory. Next, the difference between the support reaction forces of the continuous beam with multiple rigid supports obtained from the initial and final iterations is used to calculate the load of ballast on the side span main beam. Finally, the axial forces and strains of each segment of the main beam and bridge tower are obtained based on the loads applied by the main cable and stay cables on the main beam and bridge tower, thereby obtaining analytical data for the bridge in the reasonable completed state. In this paper, the rationality and effectiveness of this analytical method are verified through a case study of a SA-HCSB with a main span of 720m in finite element analysis. At the same time, it is also verified that the equilibrium force of the main beam under the reasonably completed bridge state can be obtained through iterative calculation. The analytical algorithm in this paper has clear physical significance, strong applicability, and high accuracy of calculation results, enriching the shape-finding method of this bridge type.

This study was performed to investigate the effect of kangaroo care on anxiety and confidence and gratification of mothering role in mothers of low birth weight infants. The subjects were 30 mothers of low birth weight infants, sixteen for the kangaroo care group and fourteen for the control group, whose infants hospitalized in two neonatal intensive care unit at two university-affiliated hospital. The kangaroo care was applied 9 times during the twenty six days with 40 minutes for each session. The kangaroo care provides the skin-to-skin contact during which a low birth weight infant wearing a diaper and a hat is placed on its mother's chest. The questionnaire, state anxiety was completed before beginning the first intervention. The questionnaire, state anxiety and confidence and gratification of mothering role were completed at 2 weeks after discharge. The data were analyzed by a SPSS program. The results were as follows : 1. There were no significant differences in the state anxiety between the kangaroo care and the control group before beginning the first intervention. The state anxiety was significantly lower in kangaroo care group than in control group. 2. The confidence of mothering role was significantly higher in kangaroo care group than in control group at 2 weeks after discharge. 3. The gratification of mothering role was significantly higher in kangaroo care group than in control group at 2 weeks after discharge. 4. In mothers of low birth weight infants, the state anxiety was negatively correlated to the confidence of mothering role and the gratification of mothering role at 2 weeks after discharge. And the confidence of mothering role in mothers of low birth weight infants was positively correlated to the gratification of mothering role at 2 weeks after discharge. These results suggest that kangaroo care is an effective nursing intervention for mothers of low birth weight infants in reducing the state anxiety, improving the confidence and gratification of mothering role.

This study reports on the use of the trait and state cognitive/metacognitive strategy use and the difference of the trait/state strategy use according to students' proficiency level. First of all, for checking up the trait strategy use, 119 first-grade male students in a high school completed the questionnaire on strategies which they thought they used during a reading test. Secondly, to find out their state strategy use, students took a fifteen-item reading comprehension test, followed by filling out questionnaires on cognitive and metacognitive strategies used in the test. This study employed quantitative data analysis. The results suggested that (1) the cognitive and metacognitive strategy use in the trait and state conditions are used the most by the high proficiency group and they are correlated respectively; (2) these strategies are used with statistically significant difference according to students' proficiency level, especially to the lower level students. The highly successful group uses the cognitive and metacognitive strategy in the actual test situation more than the lower proficient group; there is no difference in trait and state strategy use.

Today some many types of 3D display are developed but that are not possibly multiviewer, multiview and full parallax. Our new research work uses the Quantum optic to develop 3D display. Quantum mechanically, we can think of the first photon making a virtual transition to the second state. If the second photon appears within the lifetime of that state, the absorption sequence to the third level can be completed. When the electron, located in the third state, shifts to the first state, that electron emits one visible photon. We controlled the two invisible lights to draw a pixel in volume.

The purpose of this study was to investigate the effects of the family of origin variables on marital conflict. Seventy five married couples living together for less than 10 years were chosen from Seoul and Suwon cities. These subjects completed Korean Version of Family Adaptability and Cohesion Evaluation Scale Ⅱ, Individual Separation Scale, Family Rules Scale, Korea Certificated Egogram, and Marital Conflict Scale. The data were analyzed using descriptive statistics, paired-t test, and hierarchical regressions. The results were as follows: First, husbands and wives were different from each other in triangulation, family rules from family of origin and marital conflict. While husbands felt more strongly about their family rules than wives, wives perceived triangulation, and marital conflict higher than husbands. Second, husbands' controlling ego state, individuation, and family rules explained sixteen percents of husbands' marital conflict. Statistically speaking husbands' controlling ego state positively influenced on husbands' marital conflict. However, both of husbands' and wives' controlling ego states explained twelve percents of wives' marital conflict, and husbands' controlling ego state was statistically significant.

The Advanced Fuels Campaign Fission Accelerated Steady-state Test (FAST) at Idaho National Laboratory (INL) completed its first irradiation cycle within the Advanced Test Reactor (ATR). The test focused on the irradiation of alloy fuel forms for use in sodium fast reactors. The first cycle of FAST testing was completed and four rodlets were removed for the initial post irradiation examination (PIE). The rodlet design and irradiation conditions were evaluated using Monte Carlo N-Particle (MCNP) for as-run power history and COMSOL for temperature analysis. These rodlets include a set of low burnups (~2.5 % fissions per initial metal atoms [%FIMA]), control rodlets, and a helium-bonded annular rodlet (4.7 %FIMA). Nondestructive PIE has been completed and includes visual inspection, neutron radiography and gamma scanning of the FAST capsules and rodlets. Radiography confirmed the integrity of the experiments, revealed that the annulus in the annular fuel was filled at a modest burnup (4.7 %FIMA), and indicated potential slumping of the cooler rodlets at lower burnup. Precision gamma scanning indicated mostly usual fission product behavior, except for cesium in the He-bonded annular fuel. Future destructive PIE will be necessary to fully interpret the effects of accelerated irradiation on U-Zr metallic fuel behavior.

Purpose: This study was done to identify the relationship of trait anger, health state, physical symptoms. and general characteristics to physical symptoms and to identify factors affecting physical symptoms of elderly in urban areas. Methods: The research design for this study was a descriptive survey design using a convenience sampling. Elders (n=276), who agreed to participate in this study completed a self-reporting questionnaire. The collected data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and multiple regression. Results: Study participants reported low trait anger (M=18.61), physical symptoms (M=7.15), and moderate health state (M=3.30). The 45.4%of variance in physical symptoms was significantly explained by emotional function health state (${\beta}$=-.284, p=.013), which is one of the sub-domain of the elderly health state, and trait anger (${\beta}$=3.841, p<.001). Conclusion: Findings of this study provide that the most important factors in explaining physical symptoms for the elders in Korea were emotional function health state and trait anger. Based on the findings of this study, further nursing practice and nursing research for the elders with physical symptoms should be focused on emotional support.

We examined the associations between Latino cultural variables and four sexual behaviors among female adolescents of Mexican origin. Participants ages 14 to 19 (N = 153; 70% born in the U.S) completed surveys about four sexual behaviors (making out, receiving and performing oral sex, and vaginal sex) and cultural variables (nativity, language use, familism, and importance of female virginity). Findings indicated that participants who were born in the U.S. were less likely to have engaged in making out and vaginal sex than participants born in Mexico. Participants reporting stronger familism were less likely to have engaged in making out and oral sex than participants reporting less familism. For all behaviors, placing a greater value on female virginity was associated with lesser odds of engaging in that behavior. This study expands our understanding of the role of nativity and Latino values in the sexual behaviors of Mexican-origin female adolescents.

Objectives : The purpose of this study was to assess anger of middle school adolescents in an urban community using State-Trait Anger Expression Inventory (STAXI)-Korean and Korean Child Behavior Checklist (K-CBCL), and to determine whether specific anger expression of adolescents is associated with certain psychopathology including depression. Methods : Data were collected from 395 middle school students and their parents in Incheon city. The students completed the STAXI, Children's Depression Inventory, Korean version of Mood disorder Questionnaire, and Conners-Wells' Adolescent Self-Report Scale (Short Form), and their parents completed the K-CBCL. Results : No significant correlation was observed between aggression subscale K-CBCL and each scale of the STAXI, except anger out (r=0.704). The scores for STAXI total and respective scales were significantly higher for female students than male students. A stepwise logistic regression model was used to explore the possible predictors for depression in adolescents and lower anger control and higher anger suppression were found to be predictors for depression in adolescence. Conclusion : There is a possibility of a large discrepancy between anger that the adolescents actually feel and parents' judgment of their children's anger. It must be considered in assessment of adolescent anger and use of further structured interviews is necessary. In addition, it may be useful to consider the anger expression style in adolescents who report depressive symptoms.
