Seaports are not longer considered to be single entities for which the main activity is to load and discharge cargo, but rather as fundamental hubs within a complex supply chain serving global production networks. From a public perspective, they hold a key role in terms of their economic impact at the local, regional and national level by generating value added activity and employment. This issue is becoming increasingly pivotal for ports and their stakeholders. The objective of the study is to estimate a regression model of the value added activity and employment figures of 17 Italian ports for which there are no publications available. Concerning port system reform in Italy, the research intends to provide policy makers with a tool to measure the effects produced by ports and their importance to local communities and regions. The paper finds that in all Italian ports, the direct effects are larger than the indirect effects, and the bigger socio-economic effects are found in the biggest ports.

Structures show the phenomena of deformation and lowering of function with time-lapse by artificial environments and changes of geotechnical conditions or accumulation of initial deformation elements. This study aims the structural assessment of cultural property, Chum-Sung-Dae, located in Kyeongjucity, Korea. It was built about 1,300 years ago, and has undergone deformation and ground-subsidence with time-lapse. Non-destructive evaluation techniques were applied to the Chum-Sung-Dae, to protect it from survey. Because of this reason, 3D precise laser scanning surveying system was applied to measure the exact size of Chum-Sung-Dae, displacement and declining angles. Geophysical exploration also was applied to study the subsurface distribution of geotechnical parameters or physical properties. Natural frequencies were measured from real and model of Chum-Sung-Dae to study the dynamic characteristics of vibration and/or earthquake load and stiffness of structures.

Studies for tube spin forming have been implemented restrictively compared to spinning process, because of the complex of deformation mechanism. Especially there were not many studies by using FEM(Finite Element Method) for overcoming restriction of upper bound method. In this paper, the tube spinning process is analyzed to produce cylindrical body made by titanium alloy. In analysis, processing parameters was obtained by using upper bound method to consider material properties of titanium alloy and finite element analysis was implemented to investigate the flatness and the elongation of the titanium alloy workpiece by using ABAQUS code. The independent variables are ; material properties of workpiece, angles of roller, reduction of diameter. Three variables, two angles of roller and reduction of diameter are optimized by using the upper bound method. In this method, we can estimate the workable power, working force and reduction of diameter, and also the flatness and the elongation of workpiece by the finite elements analysis using ABAQUS/standard. The results indicates that these variables play a critical factors of spinning process for the titanium alloy and the optimum values of these variables.

Control flow information is useful in the analysis and comparison of programs. Virtualization-obfuscation hides control structures of the original program by transforming machine instructions into bytecode. Direct examination of the resulting binary reveals only the structure of the interpreter. Recovery of the original instructions requires knowledge of the virtual machine architecture, which is randomly generated and hidden. In this paper, we propose a method to reconstruct original control flow using only traces generated from the obfuscated binary. We consider traces as strings and find an automaton that represents the strings. State transitions in the automaton correspond to the control transfers in the original program. We have shown the effectiveness of our method with commercial obfuscators.

Teachers must design instruction to meet effective teaching and learning before teaching implementation. The traditional models of instructional design such as Dick and Carey, ADDIE and ASSURE have been widely applied. However, the traditional models of instructional design have limitation in that students fail in deep understanding of subject content because of break down essential goal of the unit small pieces of contents. To solve this problem, Wiggins and McTighe have suggested backward design. Backward design is a method of designing instruction by setting evaluation before choosing activities or content to teach. Therefore, this study explores the effective teaching and learning by analyzing structure of backward design and appling backward design to 'Library and Information Life' subject for information literacy education. Backward design for 'Library and Information Life' subject applies the template which Wiggins and McTighe devised for instructional design.

This discussion presents the results obtained from the implementation of a self-discovery career program using photo diaries and picture books. The program was conducted with 34 college students in 2015 during the 2nd semester of the liberal arts class. The program guided college students, who are faced with career decisions before employment, with information that helped them to understand their individual characteristics. Therefore, they could identify the jobs they aspired for or would be successful in based on that information. At this time, we believed that literature that is based on the essence of human life would be helpful. As a result, college students understood their personality type through the 1 st, 2nd, and 3rd stages of the self-development process and recognized the aspects of themselves which they had previously misunderstood, which they did not know, and which they already knew. This aided them in their career exploration. Therefore, the results showed that although self-discovery career programs based on literature are in their nascent stage, they facilitate college students in their career exploration.

Though optimization method had been used for long time for the optimal design of ship structure, design variables in the most cases were assumed to be continuous real values or it was not easy to solve the mixed integer optimum design problems using the conventional optimization methods. Thus, it was often tried to use various initial starting points to locate the best optimum paint and to use special method such as branch and bound method to handle the discrete design variables in the optimization problems. Sometimes it had succeed, but the essential problems for dealing with the local optimum and discrete design variables was left unsolved. Hence, in this paper, Genetic Algorithms adopting the biological evolution process is applied to the ship structural design problem where the integer values for the number of stiffen design variables or the discrete values for the plate thickness variables would be more preferable in order to find out their effects on the final optimum design. Through the numerical result comparisons, it was found that Genetic Algorithm could always yield the global optimum for the discrete and mixed integer structural optimization problem cases even though it takes more time than other methods.

The purpose of this study to understand the meaning of nursing through core basic nursing for nursing students before clinical practice. Participants of this study were analyzed through interviews after taking the core basic nursing skills class for 3rd graders who are currently enrolled in the Department of Nursing at M University. Seventeen students were enrolled in a K-city university as a third-year student who first performed core basic nursing skills. As a result of the study, it was derived into 3 categories and 19 thematic collections. The three categories included 1. meaning of help, 2. overcoming fear, and 3. opportunity to acquire nursing skills. The conclusion was that the first core basic nursing skills before clinical practice was a time to learn the true meaning of nursing through mutual help The difficulties were overcome with repeated practice, and the acquisition of newly learned nursing skills appeared as an effective process to experience with confidence. Therefore, it can be used as a useful basic data for counseling and guidance on the adaptation of nursing students to clinical practice, and it is expected that it will be used as a useful data for successful practice application counseling.

This study explored the psychological experiences of surviving family members of homicide victims. Nine family members of homicide victims, who could verbalize their experiences and agree to participate, were interviewed. The time between the interview and the homicide ranged from 6 months to 4 years, and all the homicide offenders were convicted prior to the study. The interview data were analyzed to identify meanings and themes using Colaizzi's method. Results showed that 472 meaningful phrases and sentences were extracted, which were subsequently organized into 48 formulated meanings, 24 clusters of themes, 16 emergent themes, and 6 categories. The six categories were related to the homicide victim, the participant, the family members, other people/the world, the offender/the offender's family, and realistic difficulties. For each category participants' experiences were described in detail. Finally, implications and limitations of this study were discussed.
