4차 산업혁명 시대에 서비스기업에서도 각기 다른 다양한 차별화 정책을 내세우고 있다. 기존까지 단순하게 고객을 만족시켜 매출을 높이기위한 방법이 아닌 좀 더 원시안적 시각을 갖고 서비스를 제공하는 직원들의 마인드와 그들이 느끼는 환경에 대한 중요성이 점차 커지고 있다. 서비스기업은 궁극적으로 고객만족, 품질향상, 가치 있는 경영 등 긍정적인 경영성과를 나타내기 위하여 끊임없는 노력을 기울이고 있으며 다른 산업에 비하여 직원에 대한 높은 의존도를 가지고 있다. 따라서 고객들을 직접적으로 응대해야하는 서비스제공자인 직원의 마음가짐과 부여된 환경, 역량 등이 직 간접적으로 고객만족 및 성과에 큰 영향을 미칠 수 있다. 궁극적인 조직의 성과를 높이고 경쟁우위를 갖추기 위해서는 결국 서비스 제공자인 직원들에 대하여 개인역량 개발, 근무환경 지원 등 다양한 형태의 사회적 지지가 중요하다고 할 수 있다. 따라서 본 연구에서는 사회적 지지가 서비스종사원의 긍정심리자본, 창의성, 직무성과에 미치는 영향에 관한 연구에 대한 후속연구로 서비스프로세스 메트릭스 가운데 대량서비스영역인 도매점, 소매점, 학교, 은행 등에 종사하는 직원들을 대상으로 동료지지가 자기 효능감을 통하여 성과에 어떠한 영향을 주는지 살펴보았으며, 그 결과 총 3개의 가설 중 3개 모두 채택되었다. 동료와 전반적인 관계가 원활해지면 자기 효능감 또한 향상되고, 자기효능감이 높을수록 직무성과도 높게 나타나며, 동료와 업무적으로나 업무이외에 전반적으로 의지할 수 있다고 느끼는 경우 직무성과도 높게 나타나는 것을 알 수 있다. 본 연구는 대량서비스영역에 종사하는 직원들을 실증분석 대상으로 한 관련연구는 전무한 실정으로 지금까지 연구와는 좀 더 다른 관점으로 접근하여 서비스기업의 경쟁력을 높이기 위한 인적자원관리 측면에서의 전략을 좀 더 효율적이고 효과적으로 제시하여 관련 시사점을 제시하고자 한다.

Men's clothing has been recently giving higher market shares to the ready-made clothes rather than the custom-tailored clothes. With many active studies on the human body and design, the ready-made clothes win popularity due to their rapid repairing, various design, and cheap prices, though they are not perfect suitable for some people. Therefore the ready-made has a weak point unable to consider all of the individual physical characteristics. However the custom-tailored clothes ate able to make clothing perfectly suitable lot their customers, though they require longer time-taking and expensive costs. In this context, this paper is design and implementation an automatic design edit system to provide a rapid and cheap service for customers on the ground of the custom-tailored clothes. In other words, this paper intended to use computer systems lot rapidly and precisely providing design dependent on the individual physical characteristics including a distorted bodies, types of the leg, and a height of the shoulder. To do so, the paper using not only studies on the human body and the custom-tailored clothes but also technical know-hows planned design for each individual body by LISP language and automatically process the design through CAD system. Consequently, the rapid and precise processing has reduced inventories and production costs, leading to supplying high quality clothes at lower prices.

Due to the rapid advancement of auto-refractor technology, most optometry shops provide refraction services. Despite their speed and convenience, the measurement values provided by auto-refractors include a significant degree of error due to psychological and physical factors. Therefore, there is a need for repetitive testing to obtain a smaller mean error value. However, even repetitive testing itself might not be sufficient to ensure accurate measurements. Therefore, research on a method of measurement that can complement auto-refractor measurements and provide confirmation of refraction results needs to be conducted. The customized optometry model described herein can satisfy the above requirements. With existing technologies, using human eye measurement devices to obtain relevant individual optical feature parameters is no longer difficult, and these parameters allow us to construct an optometry model for individual eyeballs. They also allow us to compute visual images produced from the optometry model using the CODE V macro programming language before recognizing the diffraction effects visual images with the neural network algorithm to obtain the accurate refractive diopter. This study attempts to combine the optometry model with the back-propagation neural network and achieve a double check recognition effect by complementing the auto-refractor. Results show that the accuracy achieved was above 98% and that this application could significantly enhance the service quality of refraction.
