1990년대 후반 3D Printer를 활용한 CAD/CAM 시스템의 도입은 주얼리 산업에 많은 변화를 가져오게 되었다. 2009년 FDM방식의 특허 만료를 시작으로 주요 특허가 풀리면서 저가의 3D Printer가 주얼리 산업에 보급되었다. 주얼리 대량생산프로세스는 3D Printer가 생산라인의 한 부분을 차지하는 직접제조 프로세스로 변화할 것이다. 이러한 변화에 본 연구는 3D Printer를 활용한 주얼리 제조 프로세스를 제시하고, 다른 색상의 이종금속이 접합된 주얼리 시제품을 제작하였다. 이를 통하여 3D printer의 활용범위를 높이고, 주얼리 대량생산 방법의 다양성을 제시하였다. In the late 1990's implementation of CAD/CAM systems in 3D printer has been led to many changes in the jewelry industry. Low cost 3D printer has been started advertising in the jewelry in 2009 after expiration of key patents of FDM scheme. Mass jewelry production process will vary in appliance with direct production process of 3D printer production line. The studies presented in this variation is the jewelry manufacturing process using a 3D Printer and the different metals with different colors were also produced for bonding the prototype jewelry. Increasing the possibilities of 3D printer through them, presents a variety of jewelry mass production methods.

As corporate environments diversify and become more complicated, and as expectation of societal role of companies in society increase, a company’s social responsibility is becoming a vital part of corporate activities. This study about CSR direction for corporate image enhancement seeks CSR direction through a differentiated strategy called “convergence design strategy.” This study figures out the conceptual approach and current status about CSR based on previous existing research. First in studying the CSR direction for corporate image, design standardization process was applied, configuring company CSR related factors "affordability", "differentiation", "responsiveness", and "design." Design standardization process is an important analytical framework used in this study which is widely used in design management and strategy and becomes a conceptual guideline. It is a design focused study of the process of responding appropriately to corporate goals, vision, and external needs. Thus for design management, design standardization process in this study is a conceptual diagram that, including existing general factors, considers things like corporate philosophy and changes in environmental factors and it is useful suggesting efficient CSR direction. Second, focusing on these factors, the study configures CSR in the perspective of design strategy and convergence for efficient and systematic corporate image enhancement. It presents CSR components as efficient CSR framework through convergence design strategy in the perspective of convergence. As above, this study presents guidelines for application of CSR for corporate image enhancement through convergence design strategy using interaction with related stakeholders such as regional characteristics, company characteristics, corporate vision and philosophy. Thus it presents an efficient direction of CSR for corporate image enhancement using design standardization process configuring affordability, differentiation, responsiveness, and design as CSR’s major factors.

급격한 환경변화와 기술발달에 따라 앞서가는 기업 이미지를 구축하는 것은 그 기업의 성패를 가늠하는 필수적인 요소이다. 이에 기업이미지도 일시적이고 단편적인 접근이 아닌 기업만의 통합적이면서 차별화된 이미지 구축이 요구된다. 기존의 선행연구들에서 기업이미지에 영향을 미치는 많은 요소들이 제시되어 지고 있으나, 본 연구에는 이러한 기존의 요소들을 디자인 기준화단계를 이용한 융합의 관점에서 핵심요소들을 재구성하여 융합디자인전략 프레임워크를 제시하고 있다. 본 논문에서 제시하는 기업이미지를 재구성하는 주 요소는 경영전략, 브랜드, 기술, 사회적책임, 디자인이다. 이들 요소들의 상호 작용으로 기업이미지를 구성하며, 이 과정에서 충분한 경험과 지식을 겸비한 디자이너의 중요성도 제시하고 있다. Under the environment of rapid technological development and changes, to build a corporate image of the company is essential to the existence of the company. Therefore, in the corporate image, integrated and differentiated image building is required. In previous studies related to corporate image, many factors that affect corporate image were presented. But, this study reconstructs the elements of corporate image through design standards step and the view of the convergence and presents the important factors of the convergence design strategy. The main elements are as follows: management, brand, technology, social responsibility and design. Also convergence design strategy framework is proposed through the interaction of these elements with the full involvement of experienced and knowledgeable designers.

Background: Trauma-induced deaths can be prevented by implementation of trauma system during prehospital phases and in-hospital phases. To reduce the preventable death rate (PDR), it is essential to improve the treatment strategy during the prehospital phases and the in-hospital phases. This study was designed to compares the prehospital death and emergency department (ED) death in a city before and after implementation of trauma system. Method: We evaluated the prehospital and ED data of 106 trauma patients who had died in 1991 and 2001. Trauma deaths were reviewed and the preventability of those deaths was judged by three professional panels according to appropriateness of diagnosis and treatment in prehospital phases and in-hospital phases. Deaths were classified as preventable and nonpreventable. We compared the preventable death of 1991 with those of 2001. Result: Trauma patients were 993 in 1991 and 3,094 in 2001. Trauma-induced deaths were 60 in 1991 and 46 in 2001. The death rate decreased from 6% in 1991 to 1.5% in 2001 (p<0.001). Death rate by traffic accident decreased from 90% (54/60) in 1991 to 67% (31/46) in 2001 (p<0.001). The PDR decreased from 40% (24/60) in 1991 to 13% (6/46) in 2001 (p<0.001). The time elapsed from the scene of accident to ED arrival decreased from 111 minutes in 1991 to 53 minutes in 2001 (p<0.001). There was no significant difference in Injury Severity Score between 1991 and 2001 (p=0.283). Conclusion: The rate of preventable death decreased from 1991 to 2001. Implementation and improvement of the trauma system has positive effects on trauma-induced death rate, PDR and the time elapsed from the scene of accident to ED arrival.

Purpose: Recently, the population of elderly people has been increasing rapidly all over the world. The social activities of the aging population have increased, which has also increased the number of elderly patients injured in traffic accidents. Thus, we analyzed the characteristics of elderly patients involved in traffic accidents. Methods: This study was conducted retrospectively from July 2008 to March 2009 among trauma patients involved in traffic accidents who visited Wonju Severance Christian Hospital. Patients under 18 years of age and pregnant patients were excluded. We divided the patients in two groups, a geriatrics group and an adult group on the basis of an age of 65. We compared the types of traffic accidents, the locations of the accidents, the behaviors of the patients at the times of the accidents, the use of seat-belts, and alcohol consumption between the two groups. We calculated the Revised Trauma Score (RTS), Injury Severity Score (ISS), and Trauma and Injury Severity Score (TRISS) for each group. Results: Total number of the included patients was 903, and the number of elderly patients was 181 (mean age: 71.7 ±4.9 years old). There were no significant differences in the initial vital signs, GCS (Glasgow Coma Scale), and RTS between the two groups. There were differences in the types and the locations of the crashes, the behaviors of the patients at the times of the accidents, the use of seat belts, and alcohol consumption between the two groups (p<0.05). The average ISS of the geriatric group was higher than that of the adult group (9.66±10.11 vs. 6.59±8.99, p=0.004). The mortality was higher in the geriatric group (n=17,9%) than in the adult group (n=23,2%) (p=0.004). Conclusion: The numbers of mortalities and surgical procedures were greater within the elderly group than the adult group. The average ISS was higher in the geriatric group than in the adult group. The severity of injuries due to traffic accidents was higher in the geriatric group than it was in the adult group. [ J Trauma Inj 2014; 27: 101-7 ]
