Objectives: Nowadays, the multicultural families make up significant portion of Korean population and communities. Successful re-settling in a new country can be difficult, particularly when there are disparities in dietary behavior compared to home country. The objective of the study was to investigate the dietary behavior of marriage migrant women according to their nationality in multicultural families. Methods: The primary research was conducted targeting 94 marriage migrant women who came from China (40.4%), Vietnam (26.6%), and other countries except for Japan (33.0%). We investigated their dietary behavior, such as eating attitude and food choice behavior for Korea acculturation. We also studied dietary behavior among 14 selected subjects who had high level of integration and assimilation acculturation patterns by administering the Focus Group Interview (FGI). Results: The multicultural families had more integration acculturation patterns, which could have been influenced by their nationality. Vietnamese origin has the highest cultural adaptation as marginalization pattern. The common types of Korea acculturation were integration ($3.03{\pm}1.08$), separation ($3.10{\pm}0.59$), marginalization ($3.10{\pm}0.58$), followed by assimilation ($2.84{\pm}0.51$). There were significant differences in the four types of acculturation by marriage immigrant women's country of origin (p<0.05). According to dietary behavior, 'eliminating hunger' was the most important value in a meal. Chinese marriage migrant women, who had higher level of food intake attitude significantly, also considered 'being healthy' an important value. Regarding food choice behavior, Vietnamese had lowest frequency of homeland food intake. Most of marriage immigrant women were satisfied with the Korean food, and need for education was very high with interest for cooking, good nutrition, and managing their children's dietary life. Conclusions: Coping with a change in dietary behavior is one of the biggest transitional difficulties, and family members may need support to find their familiar food items and to continue their cultural food choice behavior in the local areas. Further researches with quantitative and qualitative analysis are needed to understand the effect of dietary behavior for acculturation in multicultural families.

Purpose: The purpose of this study was to explore the relationships among pain, depression, health behaviors, and activities of daily living (ADL) in older adults after femur fracture surgery. Methods: This was a descriptive correlational study. Ninety seven outpatients aged 65 or older were selected, who agreed to participate and visited the four hospitals located in G providence. Numeric Rating Scale (NRS) for pain, a Short form Geriatric Depression Scale (SGDS) for depression, health behavior scale and Korean version of Bathel Index for ADL were used. Data were analyzed using t-test and ANOVA, Pearson's correlation and the hierarchical regression analysis in SPSS 18. Results: Pain and depression were positively correlated (r=.35, p<.001). Pain and health behaviors (r=-.30, p=.010), pain and ADL (r=-.21, p=.044), depression and health behaviors (r=-.51, p<.001), depression and ADL (r=-.29, p=.004) were negatively correlated. The variables affecting the ADL was intake of a painkiller or not (${\beta}$=-.32), age (${\beta}$=-.25), transitional period after discharge (${\beta}$=.23) and depression (${\beta}$=-.23). ADL was accounted for 33.4% in total by these four variables. Conclusion: Interventions for alleviating pain, and managing depression would be effective in enhancing ADL in older adults after femur fracture surgery.

In this study, the large scale test was performed to investigate the behavior of failure on the embankment and spillway transitional zone by overtopping. The pore water pressure, earth pressure, settlement and failure behaviors according to several reinforcing method were compared and analyzed. The pore water pressure showed a small change in the spillway transition zone and core, indicating that the riprap and geotextile efficiently reinforced the embankment, but non-reinforcement showed a largely change in pore water pressure. The earth pressure by riprap and geotextile at upstream slope and bottom core increased rapidly with the infiltration of the pore water by overtopping. And the earth pressure at crest showed a smally change due to effect of the inclined core. A settlement by riprap showed a small change and the geotextile decreased a rapidly due to failure of crest. The width of failure by riprap at intermediate stage (50 min) showed a largely due to sliding of crest. But, the width and depth of the seepage erosion after the intermediate overtopping period (100 min) were very small due to the effect of riprap than geotextile and non-reinforcement which delayed failure. It has the effect that protect reservoir embankment from erosion in the central part. The pore water pressure at the spillway transition zone due to overtopping increased a rapidly in the case of non-reinforcement, but the reinforced methods by geotextile and riprap showed a smally change. Therefore, the reinforced method by riprap and geotextile was a very effective method to protect permanently and the emergency an embankment due to overtopping, respectively.

Ecological corridor is the facility to connect two habitats fragmented by roads, dam, housing and industrial area. Critics of faunal corridors have suggested that they are simply an untested application of unproved island biogeography theory. But, everyone agree that ecological corridor is important useful structural components that help animal movement in fragmented landscapes. There are 52 ecological corridors in Korea. We investigated 43 ecological corridors of these and recorded the size of corridor, planting species, management and growth condition. We compared planting species to nearby exiting vegetation species and structure. We found that there are no considerations for many aspects of planting, for example, planting species, structure, animal migration and behavior, surrounding vegetation etc. Expecially, It was ignored management of plants, difference of surrounding vegetation, lacks of diverse planting species and structure. We suggest planting the native species of tall tree, shrub and ground cover, edge planting for transitional space between road and natural habitat, planting for foraging and breeding of target animal, diverse layer vegetation, and open space of center for rapid animal dispersal.

Smoking is considered to be one of the important risk factors associated with various health problems. Thirty seven million people in America quit smoking in the past decade, with 90% quitting on their own(Americal Heart Association, 1986). According to McAlister(1975), 70% of smokers reported that they adopted a self-help smoking cessation approach rather than a formal treatment program. In our country, although, auccessful exsmokers have used, are not available, concerns about smoking cessation have increased, recently, due to changes in social and political attitudes to health promotion. This study was conducted to help smokers who had made a decision to adopt a self-helf smoking cessation approach instead of depending on a formal treatment program. It provided a structurd way for sucessful smoking cessation by identifying change mechanism factors which have been commonly used by smokers. The subjects selected for this study were 155 university students between 20 and 29. Years of age the results from the analysis of the collected data showed that seven factors in the self-help change processes significant, and they are named, Stimulus Control, Self-Determination, Information Management, Reinforcement Management, Helpful Relationships, Dramatic Relief, and Cognitive Restructuring. All of the factors except Self-Determination represent the same change mechanisms which are proposed by Prochaska et at.(1988). Self-Determination uniformly includes items belonging to various change processes. Therefore, it might be an transitional factor including strategies related to both cognitive and behavioral dimensions. In spite of this, noted that one item which gives meaning of Self-Determination shows the highest factor loading, it is named Self-Determination.

It is of importance to determine the zero effective stress void ratio($e_{00}$), which is the void ratio at effective stress equal to zero, and the relationships of void ratio-effective stress and of void ratio-hydraulic conductivity for characterizing non-liner finite strain consolidation behavior for ultra-soft dredged materials. The zero effective stress void ratio means a transitional status from sedimentation to self-weight consolidation of very soft soil deposits, and acts as a starting point for self-weight consolidation in the non-linear finite strain numerical analysis such as PSDDF. In this paper, a new method for determining the zero effective stress void ratio has been introduced with the aid of measuring electrical resistivity of the specimen. A correlation between the zero effective stress void ratio and the initial slurry void ratio has been proposed, which can be used in PSDDF analysis as an input parameter. Combining all of the accessible experimental data, the consolidation characteristics of a dredged soil from the Incheon area has been studied in detail.

This study is a preliminary investigation into the development of a construction method that will protect a reservoir even during over flows caused by severe flooding. Through hydraulic modeling tests, the destructive phenomena caused by spillway-junction scour during reservoir overflow were modeled, and the effects on the embankment during such an overflow and the spillway-junction movements are discussed. The reservoir destruction model used the Tanbu reservoir, located in Gangwondo Chuncheon-si Namsanmyeon (H＝22 m, L＝115 m), as the model reservoir and created an embankment with a 1/60 ratio. We review the spillway-junction safety factor during overflow and embankment movement following reinforcement measures for three different cases: no reinforcement, cemented sand and gravel (CSG) reinforcement and water-blocking sheet reinforcement. The results of this study confirmed that when the spillway-junction is exposed to soil, it is very vulnerable to overflow and that a water-blocking sheet or CSG reinforcement are very effective measures in preventing embankment destruction in the long-term period.

The purpose of this study is to clarify the transitional behavior and main factor of excessive welding distortion caused by fabrication process of STS 304 vacuum vessel having double curvature for the efficient quality control of vacuum vessel. In order to do it, the predictive equations of the welding distortion in simple weldment of vacuum vessel were established by conventional finite element analysis. And the principal factor controlling the welding distortion was identified by evaluating the welding distortion of vacuum vessel in each fabrication process with FEA and simplified thermo elastic method. Based on the results, the principal factors of distortion of vacuum vessel were clarified as angular distortion and transverse shrinkage which are a source of excessive out-of plane distortion in the double curved vacuum vessel. It was expected that the FE analysis results of this study could contribute to establish the proper control method of welding distortion for double curved vacuum vessel.

The refining process and solubility of Ti in Al matrix during mechanical alloying (MA) were investigated by using X-ray diffraction (XRD), transmission electron microscopy (TEM) as functions of alloy composition, milling time and ball to powder ratio (BPR). Mechanical alloyed samples were annealed for investigating their stability and the formation behavior of$Al_3Ti$in the temperature range from$200{\circ}C$to$600{\circ}C$. It is observed from present experimental that disappearance of Ti peaks in mechanically alloyed Al-10wt%Ti is not simply attributable to the dissolution of Ti into Al, but associated mainly with extreme refining and/or heavy straining of Ti particles The annealing of the mechanically alloyed Al-Ti powders show differences in aluminide formation behavior when Ti content in Al is equal to or less than l0wt% and higher than l5wt%Ti. When Ti-content in Al is equal to or less than l0wt%, the MA powders transform directly to a global equilibrium state forming $DO_{22}- type\;Al_3$Ti above$400{\circ}C$. In the Al-Ti samples with equal to or higher than l5wt%Ti, transitional phases of cubic$Al_3Ti$and tetragonal $Al_{24}Ti_8$ are formed above$400{\circ}C$. They are stable only below$500{\circ}C$, and, $DO_{22}-type\;Al_3Ti$ becomes dominant aluminide at temperature higher than$ 600{\circ}C$.

We have presented characteristics of a transitional behavior from a premixed flame to a triple flame in a lifted flame according to the change of equivalence ratio. The experimental apparatus consisted of a slot burner and a contraction nozzle for a lifted flame. As concentration difference of the both side of slot burner increases, the shape of flame changed from a premixed flame to a triple flame, and the liftoff height is decreased to the minimum value and then increase again. Around this minimum point, it is confirmed a transition regime from premixed flame to triple flame. Consequently, the experimental results of the liftoff height, flame curvature and luminescence intensity showed that the stabilized laminar lifted flame regime is categorized by regimes of premixed flame, triple flame and critical flame. In the visualization experiment of smoke wire, the flow divergence and redirection reappeared in premixed flame as well as triple flame. Thus we cannot express the flame front of lifted flame has a behavior of triple flame with only flow divergence and redirection. To differentiate triple flame and premixed flame, ${\Phi}$ value of partially premixed fraction is employed. The partially premixed fraction ${\Phi}$ was constant in premixed flame. In critical flame small gradient appears over the whole regime. In triple flame, typical diffusion flame shape is obtained as parabolic distribution type due to diffusion flame trailing.
