This study aims to propose management items and implementation plans that can be used to manage the following topics: what components should be managed to ensure effective implementation of design leadership, which is critical to today's business management? And are all parts of a company established in accordance with the brand concept, thereby ensuring brand-oriented design leadership? Firstly, this study divided the components of design leadership management into, in a broad sense, vision, culture and platform, established sub-components that should be considered in managing each higher component, and suggested implementation plans for each component. Secondly, the implementation plans for each component were classified into workforce structures, development of brand penetration programs, distribution of time and material resources and application of identity programs. Also, each classified item was further categorized and detail implementation plans for each item were suggested. The outcomes of this study can be utilized as guidelines to evaluate whether each component is properly managed in implementing design leadership. It is also expected that these will serve as useful guides for designers, managers and consultants.

Studying employees' personality and relationship to their job would help to improve high unemployment and turnover rate in the current Korean fashion and textile industry. Based on personality which is an important influential factor, this research studied types of fashion and textile-related occupations and differences among employees' personalities related to the types. Using disclosed data from Korea Employment Information Service, 27 fashion and textile-related occupations were selected for the final analysis. Ward's Minimum Variance Cluster Analysis, MANOVA, and ANOVA by SAS 9.3 was used to analyze data. First, fashion and textile-related occupations were classified into three groups. Group 1 was mostly consisted of occupations related to manufacturing process of fashion and textile including mechanical technicians. Group 2 included occupations in garment designing and manufacturing. Designers and manufacturers including shoes, bags, and jewelry belong to group 3. Second, after observing differences in personalities among the three groups, group 1 answered that most of the personalities were not important for performance of their duties, group 2 said that only some of them were important, and group 3 regarded most of them as important. Specifically, group 1 considered precision as the most important personality but rest of the personalities not as necessary. It was revealed that personalities in relationship with other personnel such as sociality and leadership were not important. The results in this study will be used for analyzing whether job seekers' desired occupations in fashion field corresponds to their personalities and is expected to become a basic data of students' career counseling for educators.

The end plates of fuel cell assemblies are used to fasten the inner stacks, reduce the contact pressure, and provide a seal between Membrane-Electrode Assemblies (MEAs). They therefore require sufficient mechanical strength to withstand the tightening pressure, light weight to obtain high energy densities, and stable chemical/electrochemical properties, as well as provide electrical insulation. The design criteria for end plates can be divided into three parts: the material, connecting method, and shape. In the past, end plates were made from metals such as aluminum, titanium, and stainless steel alloys, but due to corrosion problems, thermal losses, and their excessive weight, alternative materials such as plastics have been considered. Composite materials consisting of combinations of two or more materials have also been proposed for end plates to enhance their mechanical strength. Tie-rods have been traditionally used to connect end plates, but since the number of connecting parts has increased, resulting in assembly difficulties, new types of connectors have been contemplated. Ideas such as adding reinforcement or flat plates, or using bands or boxes to replace tie-rods have been proposed. Typical end plates are rectangular or cylindrical solid plates. To minimize the weight and provide a uniform pressure distribution, new concepts such as ribbed-, bomb-, or bow-shaped plates have been considered. Even though end plates were not an issue in fuel cell system designs in the past, they now provide a great challenge for designers. Changes in the materials, connecting methods, and shapes of an end plate allow us to achieve lighter, stronger end plates, resulting in more efficient fuel cell systems.

The sway motion control problem of a container hanging on the trolley is considered in this paper. In the container crane control problem, the main issue involves suppressing the residual swing motion of the container at the end of acceleration, during deceleration, or for an unexpected disturbance input. For this problem, in general, many trolley motion control strategies are introduced and applied. In this paper, we introduce and synthesize a swing motion control system, in which a small auxiliary mass is installed on the spreader. In this control system, the actuator reacting against the auxiliary mass applies inertial control forces to the container to reduce the swing motion in the desired manner. In many studies, the controllers used to suppress the vibration have been synthesized for the given mathematical model of plants. In many cases, the designers have not been able to utilize the degree of freedom to adjust the structural parameters for the control object. To overcome this problem, so called "Structure/Control Simultaneous Method" is used. From this, in this paper the simultaneous design method is used to achieve optimal system performance. And the experimental result shows that the proposed control strategy is useful, to the case of that the controlled system is exposed to the uncertainties and, robust to disturbances like wind.

Engine control/performance model for helicopter simulator is one of the most important models which affect flight performance and handling quality. It is typical to develop the model based on the raw data and models from the engine designers/manufacturers. The approaches in this study were to develop the basic model based on the available resources and to tune and verify it based on the ground/flight test results. The maintenance manuals of TB3-117 which is installed in KA-32T were reviewed and the components to be simulated for the engine control model were categorized and modeled. Piece-wise linear modeling method was used for the engine performance model. The engine performance data in the engine maintenance manuals were incorporated into the engine steady state performance tables, which were incorporated with the transfer functions for the dynamic performance. Engine control/performance model was compared and tuned with the ground/flight test results. It was verified that the fidelity of the model was within the tolerances in FAA AC120-63.

Because designers want to express various elevation, architectural concrete has recently paid attention to finish material and has increasingly used in the construction. architectural concrete needs more careful and professional supervision works such as controling quality of color, texture, construction plan, and design plan. none the less, It is not clear to define process and manage methods for the construction life-cycle, which causes the expense to increase and the quality to be poor. this study will analyze concrete finish method by dividing three parts which are common, exposed and architectural concrete finish method. definition and the limit of application in architectural concrete finish method will be present by comparing three methods. Throughout an interview with a staff in charge and a case study, this paper shows the requirement and the keynote of management which are divided by three steps; the design, construction and maintenance. finally, this research provides management methods of individual steps for effective construction.

Architecture and Fashion mutually affects the shape and appearance of the other as an art of space according to the hybrid trends. Therefore, the purpose of this study is to find the correlations between the characteristics of traditional architecture types in Southeast Asia and modern fashion. Firstly, characteristics of the types obtained through the theoretical consideration of Southeast Asian architectural tradition include vertical, symmetrical, geometrical, epeated and continual structure. On the basis of these characteristics analyzed from 2013's S/S to 2015's F/W collection of Alexander McQueen, Gareth Pugh, Victor & Rolf, designers with strong creative and experimental minds who juxtaposed designs of two opposing points as well as hybrids since 2000, the following formativeness exists. First, the vertical structure of high floor is represented as a straight silhouette, a color contrast, vertical cut or wrinkle. Hence, it impresses verticality, rhythm, etc. Second, symmetrical structure of the gable roof is represented as a trapezoidal shape starting from the shoulder line or neck line widened into sleeves, impressing symmetry, dynamism, etc. Third, the geometry of the assembled is represented as vertical and horizontal bands or pattern pieces like puzzle, impressing geometry, three-dimensional, etc. Fourth, repeated structure of the weaving pattern is represented as repetitive patterns of woven fabric or printing techniques. Thus, it impresses repeatability, harmony, etc. And lastly, continuous group structure is represented as a connection of collars or hem-lines, as well as a crossing of fabric that impresses continuity, liquidity, etc.

Construction delay caused considerable losses to project parties. Avoiding construction delays is important to save costs for project stakeholders. The main objective of this paper is to identify major causes of construction delays of apartment construction projects in Vietnam. Sixteen causes of delay were identified through a questionnaire survey of 166 professionals. Factor analysis was employed to categorize these causes. The results of the survey revealed the main causes of delay of apartment projects in Vietnam are: (1) owner's and contractor'S financial difficulties; (2) lack of experienced contractors; (3) late delivery of materials; (4) late construction site handover; (5) owner's late payments for completed works; (6) low bid prices; (7) inappropriate construction method; and (8) defective works and unnecessary reworks. Factor analysis uncovered that causes of delay can be grouped under five categories labeled the five INs: incompetence, ineffectiveness, inadequateness, inapplicableness and inconceivableness. Comparative analysis between the Vietnam construction industry (VCI) and the Korea construction industry (KCI) has been performed to infer valuable lessons for researchers and practitioners in the VCI and the KCI. Comparative analysis indicated that main causes of delay in the VCI somewhat differ from main causes of delay in the KCI. However, "contractor'S financial difficulties", "late construction site handover", "unnecessary rework", "incapable designers", "site clearance difficulties" are common causes of delay in the VCI as well as the KCI. The findings of this research can be used as a guideline to overcome problems in the VCI as well as in other construction industries. Since Korea has emerged as the first largest foreign investor in Vietnam, the results of this study may be useful not only to practitioners and researchers in Vietnam but also to participants in Korea.

Instrumentation and control systems in nuclear power plants have been digitalized for the purpose of maintenance and precise operation. This digitalization, however, brings out issues related to cyber security. In the most recent past, international standard organizations, regulatory institutes, and research institutes have performed a number of studies addressing these systems cyber security.. In order to provide information helpful to the system designers in their application of cyber security for the systems, this paper presents methods and considerations to define attack vectors in a target system, to review and select the requirements in the Regulatory Guide 5.71, and to integrate the results to identify applicable technical security control requirements. In this study, attack vectors are analyzed through the vulnerability analyses and penetration tests with a simplified safety system, and the elements of critical digital assets acting as attack vectors are identified. Among the security control requirements listed in Appendices B and C to Regulatory Guide 5.71, those that should be implemented into the systems are selected and classified in groups of technical security control requirements using the results of the attack vector analysis. For the attack vector elements of critical digital assets, all the technical security control requirements are evaluated to determine whether they are applicable and effective, and considerations in this evaluation are also discussed. The technical security control requirements in three important categories of access control, monitoring and logging, and encryption are derived and grouped according to the elements of attack vectors as results for the sample safety system.

A bridge which connects Mokpo North Harbor and Goha Island is going to be constructed until 2009. For the bridges being built in the navigable water area, it is indispensible to carry out vessel traffic safety assessment from the viewpoint of shiphandlers, however, there exist no specific guidelines for the necessary conditions which the bridge designers can rely on. In this paper, traffic safety assessment procedures for the layout of the bridge are briefly introduced, and the conditions which should be taken into account at the initial design stage of the bridge are surveyed For the safety assessment of the bridge design, ship navigation simulations, such as RTS( real time simulation) and FTS(fast time simulation), are carried out, the results of which are statistically analysed to estimate the probability of collision between the ship and the pier of the bridge.
