Since world container throughput continues to grow, the main issues facing decision-makers at port container terminals are how to expand the existing container terminals and construct new container terminals. Simulations can be used in the decision making process tools due to its ease and ability to reflect the real world system. The object-oriented approach provides for both reusability and modularity that best fits these requirements. In this paper, the object-oriented approach to modeling and simulating general container terminals is presented. Simulation tools based on Visual C++ provide a user-friendly input and output environment through the use of an object class-library. This paper also presents the case study of a simulation of a real container terminal i. Pusan, Korea

Existing pedagogical issues of digital design including BIM have been focused not on potential of Digital Design but on skills of BIM or digital modeling tool. Kinetic facade can move or change material state to react surrounding environment conditions. It is a suitable design object for teaching principle of Performance Oriented Digital Design. Variables of movements affect multi-criteria of performances of kinetic facade, so different design approach from fixed facade design should be explored. Kinetic facade design process is proposed to study pedagogical issues of Performance Oriented Digital Design in this paper. Through Kinetic facade design process, students can understand conditions, variables, and performances of digital design.

In order to cope with the changes of container terminal situation in these days, many simulation studies for container terminal have been accomplished. But established simulation studies using simulation language have restrictions in model representation and difficulties in modeling of large scaled container terminal system. To make these problems better, in this paper addresses object-oriented simulation of container terminal system using a DEVS formalism. In a step of system modeling, using a DEVS formalism aim at the exact system modeling that has a basis of semantics and utilizing the object-oriented manner can flexibly cope with the changes of system environment. In this study a model was developed and verified through the simulation of some alternatives.

Personal Robot System being developed is designed to module-based system architecture for supporting internal devices have variable system platforms, environments, networks. For supporting development environment, integrating remote services, managing the interoperation among internal modules on this system design, a well-designed object oriented middleware is needed significantly. There are already some middlwares like DCOM, CORBA, UPnP, JINI, OSGi, etc. But they have some limitations to applying to Personal Robot in variable side view. We are researching for a suitable design scheme to require low system resources, to guarantee realtime services as possible, and to implement easily. In this paper, we suggest a middleware architecture have goals that are simple, light, and object oriented, so that can be used at diversity devices in Personal Robot System.

Recently, development paradigm of information system is turning into object oriented and component based, and this methodology is leading the software industry. To acclimatize aptly to this trend, users demand the assessment of software expenses to change with the appropriate model of computing costs of the environment, and some people are actually studying the concept of Object Oriented Function Point and UCP method. Especially, Object Oriented Function Point Measurement Process has good points in overcoming the bound of LOC and the existing the Function Point Measurement Process because Object Oriented Function Point Measurement Process is applicable to the early stage of development project mainly with the used cases, and valid to the life long period as the each stage of software products develops, and always understandable to communicate with users by the UML mark rules. Accordingly, this research is to measure Functional Point at ROFP and AOFP in accordance with the development project of information system by the national defense CBD methodology procedures and UML Interrelation Analysis that are recently and widely used in the developmental environment of object oriented information system. Furthermore, this study suggests the measurement method to obtain Functional Point, and identifies service function and object/class function in the correlation analysis of use case and class based on the products and UML modeling via traditional FPA model and object oriented FPA model. Above all, this study is to demonstrate the improvement of traditional Function Point Measurement Process, IFPUG-CPM and software cost basis, and reveal Function Point Measurement Process, which is appropriate to the development of object oriented information system, and suggest the evaluation results of the compatibility through case studies.

The purpose of this study is to define the tastes of middle-aged Korean men by analyzing their characteristics, such as self-image, and fashion style. This study was carried out by using the Q methodology for survey research. The results of this study are as follows; First, the self-images of middle-aged men were classified into 'comfortable, calm, neat, and gentle,' 'realistic, active, sociable, and familiar,' 'sensible, emotional, romantic, and rational,' 'refined, emotional, luxurious, and sophisticated,' and 'aggressive, sensible, realistic, and rational.' Second, by analyzing the congruity of clothing form, fashion accessory, and fashion color types, this study was classified into the following 10 fashion styles: 'modern classic,' 'sophisticated,' 'town casual,' 'traditional casual,' 'comfortable,' 'chic casual,' 'contemporary,' 'gentle classic,' 'classic sporty,' and 'soft classic.' Third, this study analyzed the self-images and fashion styles of the men, and produced the following personal tastes of middle-aged men: 'success-oriented,' 'ability possession,' 'internal stability-oriented,' 'freedom-oriented,' 'self-satisfaction,' 'individuality compromise,' 'emotional release,' 'stability-oriented,' 'practicability-oriented,' and 'youth effort' types. By combining those types with social dimensions, this study produced the following tastes of middle-aged men: 'stabilized traditions,' 'achievements with high sociality,' 'youthful individuality,' 'active self-realization,' and 'realistic, logical pursuit.' The results of this study can be used as a meaningful data for developing the marketing strategy, which reflects the middle-aged men's changed tastes.

Purpose: The purpose of this study was to identify the influence of nursing organization culture on resilience of new nurses. Methods: Participants were 1,033 new nurses with careers of less than 12 months and who were from 43 general hospitals located in Seoul, Incheon, other metropolitan cities and provinces in Korea. The data were analyzed using t-test, ANOVA, Pearson correlation coefficient and multiple regression with SPSS/WIN 24.0 program. Results: Relation-oriented culture was scored highest for perception of organizational culture by new nurses (3.35), followed by hierarchy-oriented culture (3.19), innovation-oriented culture (3.12), and task-oriented culture (2.73). The score for resilience of the new nurses was 3.49, and the first subcategories were interpersonal relationship ability 3.66, self-positivity 3.45, and self-control ability 3.36. Relation-oriented culture (${\beta}=.30$, p<.001) was the most significant factor influencing resilience of new nurses, followed by innovation-oriented culture (${\beta}=.14$, p=.001), hierarchy-oriented culture (${\beta}=.12$, p<.001), task-oriented culture (${\beta}=-.10$, p=.003) in that order ($R^2(adj. R^2)=.16$, F=47.04, p<.001). Conclusion: Findings show that for improved resilience in new nurses it is necessary to develop relation-oriented culture to provide a cooperative work environment(friendly interpersonal relation and dialogue) for new nurses and to encourage involvement of these members in the hospital culture.

Multidisciplinary Design Optimization (MDO) is an optimization technique considering simultaneously multiple disciplines such as dynamics, mechanics, structural analysis, thermal and fluid analysis and electromagnetic analysis. A software system enabling multidisciplinary design optimization is called MDO framework. An MDO framework provides an integrated and automated design environment that increases product quality and reliability, and decreases design cycle time and cost. The MDO framework also works as a common collaborative workspace for design experts on multiple disciplines. In this paper, we present the architecture for an MDO framework along with the requirement analysis for the framework. The requirement analysis has been performed through interviews of design experts in industry and thus we claim that it reflects the real needs in industry. The requirements include integrated design environment, friendly user interface, highly extensible open architecture, distributed design environment, application program interface, and efficient data management to handle massive design data. The resultant MDO framework is datasever-oriented and designed around a centralized data server for extensible and effective data exchange in a distributed design environment among multiple design tools and software.
