This study conducted a survey to find out dermatitis patients' preferred garment performance and their sentiment in spring/summer knitwears. SPSS 12.0 program was used for factor analysis, frequency analysis, T-test, ANOVA, and Duncan test. The result was as follows; First, in garments, patients required 'health hygiene', 'practicality in use care', 'skin contact' and 'easy movement'. Especially, 'skin contact' is an important property to be considered in patients' clothes. Second, in garment sensitivity, patients importantly considered 'modesty', 'feminine', 'boldness', 'decency', 'easy movement', 'youth', and 'simplicity'. Third, patients preferred simple and modest plain knitwear in light color with thin and soft fabric such as plain knit. And especially, dot pattern in knitwears should be avoided. Fourth, the preferred style of patients was that 'appropriately fit with suitable ease.' They also preferred 'front closed,' ; 'boat neckline' and 'V neckline'; 'raglan sleeve' and 'set-in sleeve'. For hem trim, they preferred 'rib'. Male preferred simple and plain style with round collar of 'tubular trim' and 'rib trim', while female preferred sophisticated and characteristic style with setin sleeve.

The purpose of this study is to conduct a questionnaire survey on the actual conditions of the working uniform and protective equipment put on by street cleaners, then to identify their inconvenience and problems and to draw solutions to improve them, and finally to design a spring-and-autumn street cleaner uniform which has enhanced functionalities such as motional flexibility, safety and soil proof. The questionnaire survey of this study was done by street cleaners who were in charge of street cleaning and collecting the recyclable waste. The result of this study, easily worn-out parts of the working clothing were the sleeve hems and the front part on the upper uniform, and the trouser hems and zipper on the lower uniform. Easily soiled parts were the sleeve hems, parts of arm on the upper uniform, and the trouser hems and knee parts on the lower uniform. Based on the results of the questionnaire survey, the sample uniforms were designed in consideration of material, design and pattern. A soil-proof material was used for easily soiled parts such as sleeve hems, knee parts and trouser hems. Reflective material was applied to the parts such as chest, back and the side lines of sleeves and trousers to raise visibility in working and to ensure safety. A crease was given to each side of the back. The height of sleeve cap was lowered to lift the motional flexibility of back and arm parts. Darts were applied to elbow and knee parts for a three-dimensional design. Gussets were inserted in the thigh part to give it activity. Then quantitative evaluation and a sensory evaluation, which was composed of outward appearance, motional flexibility and fitness for field operation, were conducted. According to these evaluations, the sample uniform was found to be more satisfactory than current uniform.

Maritime deck machinery relies heavily on the importation of components produced by overseas companies. Our research defines design parameters for hydraulic winch regulators used in maritime deck machinery. Using Amesim, we were able to conduct 1D modeling, and utilizing CFS then enabled us to create 3D models. These models were analyzed in our research for changes in pressure on each port that resulted from the regulator's spring constant and changes in the primary tension-compression field. Our research then analyzed alterations in traits caused by changes in the length of overlap between the spool and sleeve. Last but not least, our research analyzed the trait alteration resulting from changing the interval between the spool and sleeve. We believe the results of our research can be used to design a hydraulic winch regulator used in maritime deck machinery that does not require importation.

The purpose of this study were to investigate clothing design preference (style, color, fabric print, kinds of fabrics) & satisfaction with the fit of ready-to-wear clothing for older Men. For this study, the questionnaires were administered to 650 older men in seoul from June to August, 1998. Employing a sample of 504 data were analyzed by mean, frequency and percent. With respect to clothing design preference, they prefer suit the style of outdoor clothing on going-out. On distinguish clothing into formal wear & casual wear, the color preference due to seasons has difference in spring clothing. Regarding the degree of fabric pattern preference, nonpattern single color fabric has occupied in formal wear, pattern in casual wear. Regarding the degree of fabric preference, they take a serious view of shape preservation in formal wear, utility (washing, sweat absorption) in causal wear. Suit has the lowest satisfaction in the fit of ready-to-wear clothing. Sleeve length the lowest in the degree of satisfaction for each part.

This study aims to develop a spring/fall motorcycle jacket for quick service transporter. Depending on the results of the previous research, this study produced the tested jacket which was improved in material, pattern, and design. For the tested jacket, 100% polyester fabric excellent in strength, durability and abrasion-resistance was selected as a major material, and Cordura was used as a partial material to improve the strength and abrasion-resistance of the sleeve side lines, elbow and shoulder areas. The retro-reflection material was applied partially in order to improve visibility of the jacket in the night or in a dark place. A total of 7 pockets were composed in the jacket for the sufficient storage spaces. The functional design elements such as the 2-way zipper and the placket at the center front, the action pleats at the upper part of back armholes, the pit-zip at armpit were applied. In addition, the sleeve pattern was bent with the shape of elbow curvature in time of driving and the back length of the jacket was lengthened 4cm. As a result of the appearance assessment, there was a significant difference from the existing jacket in all items but chest size, shoulder width, cuffs circumference, and jacket hemline circumference. In motion adaptability and field activity appropriateness assessments, the assessment grade for all items was found to be commonly higher than that of the existing jacket, and thus, the tested jacket was assessed to be suitable for a motorcycle jacket design for the quick service transporters.

The free vibration of a spinning flexible disk-spindle system supported by hydro dynamic bearings (HDB) in an HDD is analyzed by FEM. The spinning flexible disk is described using Kirchhoff plate theory and von Karman non-linear strain, and its rigid body motion is also considered. It is discretized by annular sector element. The rotating spindle which includes the clamp, hub, permanent magnet and yoke, is modeled by Timoshenko beam including the gyroscopic effect. The flexible supporting structure with a complex shape which includes stator core, housing, base plate, sleeve and thrust pad is modeled by using a 4-node tetrahedron element with rotational degrees of freedom to satisfy the geometric compatibility. The dynamic coefficients of HDB are calculated from the HDB analysis program, which solves the perturbed Reynolds equation using FEM. Introducing the virtual nodes and the rigid link constraints defined in the center of HDB, beam elements of the shaft are connected to the solid elements of the sleeve and thrust pad through the spring and damper element. The global matrix equation obtained by assembling the finite element equations of each substructure is transformed to the state-space matrix-vector equation, and the associated eigen value problem is solved by using the restarted Arnoldi iteration method. The validity of this research is verified by comparing the numerical results of the natural frequencies with the experimental ones. Also the effect of supporting structures to the natural modes of the total HDD system is rigorously analyzed.

Consumers are addressing the issue of dimensional dissatisfaction by repairing clothes, experimenting with style changes, and looking for cost-effective solutions that result in better-fitting garments. This study investigated the repair status by type of clothing, analyzed the method and frequency of repair by type of clothing category and season, and analyzed consumer redesign activities. The findings revealed that upper garments, such as T-shirts, jumpers, jackets, dress shirts, and dresses, were frequently repaired. The common modifications to upper garments included(in order of frequency) shortening sleeve length, shortening overall length, reducing garment width, zipper repair, and adjusting sleeve width. Lower garments, such as pants, jeans, skirts, and training pants, followed in terms of repair frequency. The modifications to lower garments included(in order of frequency) shortening length, reducing width, adjusting waist width (both narrowing and widening), replacing elastic bands, zipper repair, and lengthening. Repairs were more frequently conducted in the order of autumn, winter, spring, and summer. Repair methods varied depending on the clothing type and alterations involved to the length and width of garments and the replacement or removal of old sections. Redesigning clothing as a recycling method was found to enhance the cost-effectiveness of the collection. The study further confirmed the sustainability aspect of redesigning and reusing clothing.
