The characteristics of metabolic pathways make them particularly amenable to layered graph drawing methods. This paper presents a visual Java-based tool for drawing and annotating biological pathways in two- and a-half dimensions (2.5D) as an alternative to three-dimensional (3D) visualizations. Such visualization allows user to display different groups of clustered nodes, in different parallel planes, and to see a detailed view of a group of objects in focus and its place in the context of the whole system. This tool is an extended version of J2dPathway.

Ship structures are subject to severe environmental loads causing appreciable hull girder bending which in turn affects the piping system attached to the main hull in the form of a displacement load. While this load may cause failure in the pipes, loops have been widely adopted as a means of preventing this failure, with the idea that they may lower the stress level in a pipe by absorbing some portion of the displacement load. But since such loops also have some negative effects, such as causing extra manufacturing cost, deteriorating the function of the pipe, and occupying extra space, the number and dimensions of the loops adopted need to be minimized. This research developed design formulas for pipe loops, modeling them as frames composed of beam elements, where not only bending but also shear deflection is taken into account. The accuracy of the proposed design formulas was verified by comparing two results respectively obtained by the proposed formulas and MSC/NASTRAN. The paper concludes with a sample example showing the efficiency of the proposed formulas.

This study focuses on semiotic significance of clothing, showed in visual mass media. This study will look into what general public understand from clothing and what influence clothing on visual mass media exert on fashion. This study employs an example, "Aein(sweetheart)", which was televised from 09/02/1996 till 10/23/1996. Some specialists(master′s degree or doctoral degree holders, or professors) of Clothing and Textile picked and analyzed scenes with specific clothing. The theoretical grounds of the analysis are 1) in what procession the significance operate from the view of mythological symbols by Bart, 2) what influences clothing on TV dramas exert on fashion. The outcomes of the study are followings: First, clothing′s signifying proces hs two dimensions; linguistic dimension and mythological dimension. Linguistic dimension which is regarded as general and unvariable and is related to the reproductive signifying operation, contributes to the creation of the characters including the characters′ social activities, professions, social or economic position. Mythological dimension which is related to the cultural and implicative signifying operation, played an important role in the development of the drama. Thus, it operates to create and deliver images including that atmosphere of he drama and the development of the story. Second, the TV media which is characterized with the form of centralized transmission and individual reception and the ability tro readily lead the fashion, has huge influence upon the fashion by properly creating mythological or linguistic dimension of the clothing in the drama, arousing the public′s sympathy, and stimulating the public′ immitation or conformity mentality.

This study was intended to identify the differences in perception of image words and perception dimension of desired image according to sex variable for college students in a school context. Data were collected by questionnaires distributed to 443 college students from August to September of 2000. After eliminating incomplete questionnaires, 396 were analyzed. As results of factor analysis, 7 desired image factors were determined for male and female, respectively. On the basis of these results, major perception differences were identified according to sex variable. Differently-perceived image words were as fellows: For intellectual image, male relates it with sporty while female relates it with graceful; for masculine image, male relates it with mature while female relates it with sporty; and for feminine image, male relates it with sexy and graceful while female relates it modest, pure, and cute. Multidimensional scaling was employed to determine the perception dimension of desired image. Two dimensions were accepted to interpret the results for both sex, respectively. 'Feminine-masculine' and 'conspicuous-plain' were criteria for male students, while 'unnatural-natural' and 'feminine-masculine' were criteria for female students.

Background: The dimensions and shape of the forehead determine the esthetics of the upper third of the face. Korean young people consider a broad and smooth, rounded forehead more attractive. As a result, frontal augmentation becomes more popular in patients with dentofacial deformities. Various surgical procedures and materials have been used in frontal augmentation surgery, with associated advantages and disadvantages. Silicone is a good candidate for frontal augmentation. The author presents two cases of esthetic frontal augmentation with a prefabricated silicone implant in female patients with dentofacial deformities. Case presentation: In case 1, a 24-year-old female patient underwent frontal augmentation surgery with simultaneous maxillomandibular and zygomatic osteotomies to correct facial asymmetry. A silicone implant was fabricated preoperatively using a positive template stone mold of her forehead. In case 2, a 23-year-old female patient underwent total facial contouring surgery including frontal augmentation for improved facial esthetics. A computed tomography (CT)-guided rapid prototype (RP) model was used to make the silicone implants. The operative procedure was safe and simple, and the silicone implants were reliable for a larger degree of frontal augmentation. Six months later, both patients had recovered from the surgery and were satisfied with their frontal shape and projection. Conclusions: Frontal augmentation with silicone implants can be an effective adjuvant strategy to improve facial esthetics in patients with a flat and narrow forehead who undergo orthognathic reconstruction or total facial contouring surgery.

The purpose of this study was to identify the effect of job characteristics, career commitment, and the fitness relationship between the two variables on the nurses' job attitude(job involvement and job satisfaction). Data were collected using self-reporting questionnaire taken by 594 nurses working at eight university hospitals in Seoul and Chungbuk area. Data were analyzed using t-test, ANOVA, factor analysis, Cronbach's alpha coefficients, multiple regression through SAS program. The results of the study were as follows : 1. Three dimensions(task significance, skill variety, autonomy) of five core job characteristics have positive influence on job involvement and only one dimension(autonomy) of five core job characteristics has positive influence on job satisfaction of nurses. 2. The level of career commitment have positive influence on both job involvement and job satisfaction of nurses. 3. There were significant differences between ${\lceil}$high job characteristics-high career commitment${\rfloor}$ groups and ${\lceil}$high job characteristics-low career commitment${\rfloor}$ groups for job involvement and job satisfaction in nursing organization.

Today's health care environment is rapidly changing and nurse administrators' leadership styles need to identify in nursing organization to achieve organizational objectives. By Bass(1985), transformational leadership stimulates the subordinates to be creative and achieve organizational objectives and is related to job satisfaction, job involvement, productivity, and organizational commitment. Transformational leadership process consists of charisma, intellectual stimulation, individual consideration. The purpose of this study was to identify the effect of transformational leadership and personal characteries on nurses' job involvement. The subjects for this study consisted of 594 nurses from 8 University Hospitals and General Hospitals. The data were collected by personal characteristics scale, transformational leadership scale, and job involvement scale. The factor analysis, Cronbach's alpha analysis, Pearson correlation analysis, multiple regression analysis and hierarchical multiple regression analysis were used for the statistical method. The results of this study were found that (1) charisma dimension of transformational leadership has positive influence on nurses' job involvement ; but another two dimensions (intellectual stimulation and individualized consideration) did not showed significant effect on job involvement (2) nurses' personal characteristic (internal locus of control) moderated the effect of transformational leadership on job involvement.

This paper concerns about an experimental investigation about steering performance of tracked vehicle on extremely soft soil based on DOE(Design Of Experiment) using L8 orthogonal Array. A tracked vehicle model with principal dimensions of $0.9m{\times}0.8m{\times}0.4m$ and weight 167kg was constructed with a pair of driving chain links driven by two AC-servo motors. The tracks are configured with detachable grousers, the span of which can be varied. Deep seabed was simulated by means of bentonite-water mixture in a soil bin of $6.0m{\times}3.7m{\times}0.7m$. Turning radii of vehicle and torques of motors were measured with respect to experimental variables; steering ratio, driving speed, grouser chevron angle, grouser span, grouser height. The effects of experiment variables on steering performance are evaluated.

In this paper, we proposed the grating parallel plate waveguide structure for converting a linearly polarized wave to a circularly polarized wave. For the design of the polarizer, the moment method and Floquet's theorem are applied under two assumptions that the incident wave is a plane wave and the structure is infinitely periodic. In order for the more precise design, we performed the near-field analysis for the finite polarizer structure using MATLAB. By comparing with the measured results obtained by the near-field arrangement, we verified the correctness of our near-field analysis. By taking the ideal assumptions considered in the initial design procedure into account, newly designed modified dimensions for the polarizer was suggested which give improved performance.

This paper presents monopole antenna with electromagnetically coupled feed and its equivalent circuit model. The proposed structure is consists of a rectangular disk-loaded monopole and a probe with rectangular spiral strip line feed. The rectangular disk-loaded monopole is represented by parallel RLC resonant circuit and the probe with rectangular spiral strip line feed is represented by series RLC resonant circuit. Therefore broad bandwidth can be achieved through electromagnetic coupling between these structures that generate two resonances within close frequency range. The antenna with electrical dimensions of only 0.075λ$\sub$0/${\times}$0.075λ$\sub$0/${\times}$0.075λ$\sub$0/ has 16.5 % fractional bandwidth for VSWR$\leq$2 at a center frequency of 2.038GHz.
