This paper introduces the use of network theory to model and analyze disparate ship design information. This work will focus on a ship's distributed systems and their intra- and intersystem structures and interactions. The three system to be analyzed are: a passageway system, an electrical system, and a fire fighting system. These systems will be analyzed individually using common network metrics to glean information regarding their structures and attributes. The systems will also be subjected to community detection algorithms both separately and as a multiplex network to compare their similarities, differences, and interactions. Network theory will be shown to be useful in the early design stage due to its simplicity and ability to model any shipboard system.

Purpose - This study attempted to identify any influencing relationships, between the antecedent variables and the members' innovative work behavior, which were expected to influence organizational performance based on the extended theory of planned behavior (ETPB). Research design, data, and methodology - The survey was conducted on SMEs in Seoul and its metropolitan area. A total of 158 copies of effective questionnaires were used and were analyzed through correlation analysis, regression analysis, and multiple regression. Results - Self-efficacy, value, intrinsic motivation, and self-enhancing bias have been found to have a positive relationship with innovative work behavior. In addition, transformational leadership was found to moderate the existence of a statistically significant negative influence between value, intrinsic motivation, and innovative work behavior. Conclusions - The results suggest that leaders will be successful in winning members' trust through conducting their behaviors in accordance with the applicable ethical and moral standards and through their fair, transparent, and legitimate management practices with an attitude of 'taking the initiative and setting an example', and this will help solve such problems.

In optical storage device system, there are several research topics to increase its recording density. The main idea is reducing wave length of laser diode and magnifying the number of numerical aperture (NA). In conventional optical system NA cannot be over the unity in the air because of its diffraction limit. But it is possible to overcome its limitation of unity in near field using Solid Immersion Lens. In this work, the mathematical Solid Immersion Lens (SIL) design process was illustrated by using near field theory. Also, numerical SIL design parameters were calculated by means of CODE V. Through the work, we propose the new type of SIL for high density optical recording systems.

The major objective of this paper is to clarify the effect of constitutive laws on bulk forming design based on the ideal flow theory. The latter theory is in general applicable for perfectly/plastic materials. However, its kinematics equations constitute a closed-form system, which are valid for any incompressible materials, therefore enabling us to extend design solutions based on the perfectly/plastic constitutive law to more realistic laws with rate sensitive hardening behavior. In the present paper, several constitutive laws commonly accepted for the modeling of cold and hot metal forming processes are considered and the effect of these laws on one particular plane-strain design is demonstrated. The closed form solution obtained describes a non-trivial nonsteady ideal process. The design solutions based on the ideal flow theory are not unique. To achieve the uniqueness, the criterion that the plastic work required to deform the initial shape of a given class of shapes into a prescribed final shape attains its minimum is adopted. Comparison with a non-ideal process is also made.

The shape of an industrial product has to be determined within the constrained conditions of keeping firmly many kinds of functional and performance requirements. On the other hand, the configuration of artistic work would be created desirably using the sense of aesthetics, even if conflicting slightly with these requirements. The development of a methodology for an aesthetic design founded on human sensitivity is becoming highly desirable in recent years. In this paper, a method of measuring beauty quantitatively for an artistic evaluation if proposed using the aesthetic cognitive theory and the optimum configuration could be found by a search using the genetic algorithm. Furthermore, an expression of optimum ship appearance can be gained as graphics.

Ji Cheng's great work on garden design, the 'Yuanye'(Craft of garden), written in 1631 and originally published in 1634 is the first surviving manual on landscape gardening in the Chinese tradition. This study aims at investigating not only Ji Cheng's life, achievements companionship and design activities, but also the xylographic copies, literary style, and framework of Yuanye in their historical context in order to provide the bases for further study, Ji Cheng was exellent in poetry and painting. And he constructed Dongdiyuan in Changzhou around 1623, Wuyuan in Yiaheng in 1631, and Yingyuan in Yangzhou around 1634 But no poems, paintings, and gardens designed by hi shill exist Therefore his design phi philosophy is able to be interpreted only by his work, Yuanye. After publishing, Yuanye fell into obscurity for several centuries in Chlna. It was redescovered and reprinted for the first time in 1931. Yuanye is composed of prefaces and main text The main text is divided into 'the Theory of Construction' and 'on Gardens', and the latter also into 10 sections. In this text Ji Cheng explains the aesthetic principles underlying garden design and the appropriate emotional response to various efftcts Especially, he emphasizes the importance of basin the garden design on the taxi ting nature and features of landscape and making use of natural scenery. The literary style of the book is highly mannered, and there are so many poetic descriptions and Ji Cheng's native Jiangsu dialects. So the translation of the original text is very difficult After this, the major design concepts of Ji Cheng's landscape gardening theory and whole network of these concepts have to be studied.

Objective: This research focuses on the working environment of office workers and aims to propose an ideal seating posture and chair design. Background: Generally, office workers having to seat in a fixed posture for long periods of time tend to suffer from an increased rate of musculoskeletal disorders. Method: The measurement and survey of 123 office workers on their working conditions and literature survey will lead to a suggestion of an ideal seating posture and workstation design theory. Results: Work environment satisfaction appeared low for chair and desks. Work-related pain over the last year was experienced among 47.2% of the respondents in shoulder (34.2%), neck (30.9%). Observation of working posture revealed that only 27.6% of workers utilize backrest during work. Conclusion: Office work embodies many situations where risks of musculoskeletal disorders may be high. Thus, the seated workplace must be set up to allow proper seating posture for workers. Application: The results of this study can be applied as baseline data for preventing musculoskeletal disorders of office workers.

This study identifies how management theory and philosophy work in conjunction with and support one another as both are critical to understanding leadership concepts and viewing the design organization holistically in terms of organizational behavior and performance. This paper analyses data from an in-depth single-case study at management in interior design organization in Korea. Two new 'most efficient and effective way' to achieve the goals of the design organization has been launched. The first was organizational behavior and performance, and the second a needed new paradigm of management skills. Organizational culture affects organizational effectiveness in design because it can (a) provide an organization with a competitive advantage, (b) improve the way an organizational structure works, and (c) increase the motivation of designers to pursue organizational interests. Moreover, the result of research creates paradigm of thinking that how leaders in the design organization need to focus on innovative and strategic systems to gain competitive advantage and enter global markets; a key inter-organizational cooperation strategy to achieve a targeted goal.
