This study presents a T-shirt design process that utilizes modernized traditional patterns; in addition, it also includes various modernization techniques for Korean traditional patterns. T-shirts are a representative casual wear item worn in everyday life, especially among young people. The association of traditional elements and public goods such as T-shirts effects the diffusion of the Korean image into global society. Through the whole design process, target groups and design concepts were determined first: collegiate students as well as clean, natural, refined, simple and sporty image, respectively. Subsequently, Dokkaebi, lotus, Dangcho, dragon and Taegeuk patterns were selected as traditional pattern sources. Along with the technique of the division, transformation, and configuration of original patterns, the combining method of geometrical figures, stripe patterns, and check patterns with traditional patterns was helped create modernized traditional motives. Finally, T-shirt designs with a Korean image were developed with the harmonized deployment of modernized motives and color planning. The survey showed that designs had a clean, natural, refined, simple and sporty image that was preferred by collegiate students. This study is relevant in three aspects. First, the design process of modernization was very creative to combine traditional patterns and basic figures. Second, this study expanded the scope of traditional image design to casual wear to promote the Korean image to young people all over the world. Third, the whole design process, from planning to final product development, presented in this study is applicable to other design processes.

Background The current indications of cardiac implantable electronic devices (CIEDs) have expanded to include young patients with serious cardiac risk factors, but CIED placement has the disadvantage of involving unsightly scarring and bulging of the chest wall. A collaborative team of cardiologists and plastic surgeons developed a technique for the subpectoral placement of CIEDs in young female patients via a transaxillary approach. Methods From July 2012 to December 2015, subpectoral CIED placement via an axillary incision was performed in 10 young female patients, with a mean age of 25.9 years and mean body mass index of $20.1kg/m^2$. In the supine position, with the patient's shoulder abducted, an approximately 5-cm linear incision was made along one of the deepest axillary creases. The submuscular plane was identified at the lateral border of the pectoralis major, and the dissection continued over the clavipectoral fascia until the subpectoral pocket could securely receive a pulse generator. Slight upward dissection also exposed an entrance to the subclavian vein, allowing the cardiology team to gain access to the vein. One patient with dilated cardiomyopathy underwent augmentation mammoplasty and CIED insertion simultaneously. Results One case of late-onset device infection occurred. All patients were highly satisfied with the results and reported that they would recommend the procedure to others. Conclusions With superior aesthetic outcomes compared to conventional methods, the subpectoral placement of CIEDs via a transaxillary approach is an effective, single-incision method to hide operative scarring and minimize bulging of the device, and is particularly beneficial for young female or lean patients.

Purpose: This paper studied about the integration for management system of representative international standard related to sustainable development. The well-known International standards such as ISO 9001, ISO 14001 and OHSAS 18001 (ISO 45001) can be operated in accordance with the organizational situation individually, or in a variety of ways of integration. It can be applied to help organizations utilizing the newly established "ISO IEC Directive Part1 Annex SL", when integrating quality, environmental and safety & health management systems based on international standards. Methods: We conducted an empirical survey of management executives and experts to study how three factors (management systems, organizational capabilities and integration methods) could affect business performance. Results: The questionnaire was analyzed using AMOS structural equation model. Quality, environmental and safety and health management systems affected management performance, and integration methods of management system affected business efficiency, risk performance and financial performance. Integration method is also important because organizational competence affects various aspects of integrated management. However, factors that affect integration should also be considered in terms of organizational capabilities. This is because organizational capacity influences the integration plan. Conclusion: To integrate the document system at the strategic level, management should actively participate in integrated operations to integrate organizations, eliminate duplicate tasks, and foster document integration experts to reflect the characteristics of individual standard. In the case of document integration, quality management is focusing, but once ISO 45001 is issued, the use of Annex SL is increasing, and Quality, environment and safety & health integration will also be expanded. It is possible to increase the effect of integration by strategically approaching and establishing organization document system rather than simple integration according to management system standard arrangement.

Increasing traffic volumes and excessively high speeds on national highways through small towns often increases the frequency of accidents. Extensive paved areas, narrow sidewalks, median barriers and little greenery have resulted in a dangerous and destructive living environment for residents. The reason for this problem is that throughways were expanded without considering the harmony between the throughways and the small towns. Construction of bypasses and reclassification of highway functions would solve the problem by reducing vehicle speeds in small towns, but this method is too costly and time consuming. Therefore, this study analyzes national highways through small towns as a case studies using positive guidance in order to improve safety and develop alternatives. As a result of the case study, the biggest problem was observed to be the excessively high vehicle speeds, This study also identified places were information should be given or posted but is currently absent. Therefore, this study concludes that notional highways through small towns need installation of speed reduction facilities and additional information provision to drivers.

We tried to establish the culture method of the chondrocyte isolated from the epiphyseal cartilage and to investigate morphological changes of chondrocyte cultured with enzyme-digested costal cartilage, the perichondrium and experimentally damaged meniscus of rabbit. De novo chondrocyte pellets were prepared from epiphyseal plates by culturing isolated epiphyseal chondrocytes from 4 week. old rabbits. We morphologically assessed the cartilage formation of the chondrocyte culture with enzyme-digested costal carilage, the perichondrial culture, the cultured chondrocytes transplants into experimentally damaged meniscus of rabbits, the perichondrial culture, the cultured chondrocytes transplants into experimentally damaged meniscus of rabbit. In the 24 days, the epiphyseal chondrocytes maintained the typical phenotypes of the partial nodular cell formation. The 30 days cryopreserved chondrocytes showed abnormal and irregular shape. In the type II collagen added culture, the chondrocytes showed expanded rough endoplasmic reticulum and small and large round-like vesicles of processes. In the type IV collagen added culture, the chondrocytes showed large perinuclear vaculoes and abundant well-developed rough endoplasmic reticulum of processes. In the culture with enzyme- digested costal cartilage and the perichondrial culture, the chondrocytes showed a few swelling rough endoplasmic reticulum and vacuoles. The cultured epiphyseal chondrocytes maintained typical phenotype and the chondrocytes were grown faster and maintained more typical phenotype in the type II and IV collagen added culture. The transformed chondrocytes secreted abundant extracellular matrix in the type II collagen added culture, and showed processes in the type IV collagen added culture. The perichondrial chondrocytes were grown faster and their implants were able to transplant. The cultured chondrocytes transplanted into experimentally damaged meniscus were adapted between the meniscus tissues. And the immunocyto-chemical reaction of the type II collagen of the chondrocytes were found to be maintained. The chondrocytes cultured cartilage. The chondrocytes secreted abundantly. The cultured chondrocytes transplanted into experimentally damaged meniscus changed immature cells into enlarged mature cells with extracellular secretion.

It is inevitable to have cutting line to get the 2D pattern from 3D body surface. In this paper the efficiency of curvature plot as a cutting line in the process of flattening 3D surface was investigated. As reference, basic clothing construction line was adopted to divide the 3D surface into small blocks to make the flattening process easy. Female dummy as well as human body were scanned and surface of the upper body was segmented using curvature plot and basic constructing line. 2D tight-fit pattern was developed using three software, the RapidForm 2004, 2C-AN and Yuka CAD. Gap between clothes and body, and the clothing pressure on the body was observed to determine the fit of the clothes. As results, clothes constructed with blocks divided by curvature plot displayed a similar level of tight fit as compared with those by basic construction line. It was found that curvature plot is effective method as a segmentation of the 3D surface even for the actual body which does not have any previous reference line. It is expected that application of curvature plot will be expanded in 3D apparel technology.

Purpose: This study was performed in order to improve problems and to seek the efficient operating plan by surveying and analyzing the actual status of operating the agricultural machinery rental business supported by the government. Method: The data was collected through two times of survey targeting lease business operators and the leasing business reports published for the past 3 years ('08~'10) 120 cities and counties. Results: As a result of surveying 120 cities and counties nationwide of operating the agricultural machinery rental business, 96% of agricultural machinery rental businesses were indicated to be operated in the form of short-term rent for about 1~3 days centering on small-sized agricultural machinery and attachment for upland crop. As for the unit number of possessing rental agricultural machinery and the purchase cost, it was indicated to be greatly reduced the agricultural machinery for rice farming and to be expanded into upland crop whose mechanization is insufficient. The annual rental days ('10) are 9.5 days/unit, thereby being a little insufficient. Rental fee for 1 day is 0.2~0.8% of the initial purchase cost of agricultural machine, thereby being greatly lower compared to 2.0% (annually 10-day rent) of the proper rents, resulting in being demanded improvement. Conclusions: To be continuously driven the rental business of agricultural machinery with having the ability to propagate, it is judged to be likely to necessarily collect optimum rental fee in consideration of rental days as well as increasing the use days per unit by buying the agricultural machinery, which is secured the rental demand, and by possessing the reasonable unit number.
