One of the primary means of achieving global competitiveness is to reduce the COPQ in our business units. Although the COPQ is not known precisely, it is known to be very high. Also, it may be underestimated by the hidden costs due to non-value added activities, such as potential lost sales, costs of redesign due to quality reasons, and extra manufacturing costs due to defects, etc. In any manufacturing or service operation, all actions and resource expenditures of a company should be focused on creating value for customers. Any activity or resource of not creating the value for customers could be regarded as waste, which consequently causes the COPQ. In this paper, a management system is developed for evaluating and reporting the COPQ in our business units, based on the Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) roadmap.

In 1997 the Asian Foreign Currency Crisis hit Korean shores. In its wake, Korean consumers demanded cost-saving solutions which will increase both the use-life and the fuel efficiency their vehicles. Bullsoneshot's effects include increases in gas mileage as well as cleaner cylinders, intakes and exhaust valves, the product was welcomed by an explosive demand from people driving older cars in an adverse economy. The history of Bullsone can be categorized as two major stages. The First stage is lunching era of "Bullone Shot" following competitor brand. The second stage is extension stage of brand and line based on Bullsone's positive brand equity. Mr. Hyun Woo Shin, formal CEO of OXY inc. and also formal vice president of OCI (Oriental Chemical Industries) take charge of New CEO of Bullsone. He energetically push the Bullsone's family brands and got a desirable results. He also setup ambitious goal : reach 100bn KRW in gross sales within 3 years. "Ripping itself free from 30~40 bn KRW sales range in which the company has stagnated in the last 10 years, Bullsone intends to be aggressive enough in marketing to reach 150 bn KRW in sales in 2013, and reach 700 bn KRW by 2018."

Purpose - This study aims to quantify the long tail effect in the digital economy. It also investigates the role of digital platform before and after the COVID-19 pandemic. Design/methodology/approach - We take advantage of a granular data set from one of the biggest digital platforms in Korea. Rather than computing the absolute number of products sold or the Gini coefficient, we estimate the slope of the log-linear relationship of the non-parametric sales distribution. Findings - We find that the use of online food order and delivery services is positively associated with individual restaurant's sales growth. We also document that the long tail effect is increasing over time. Long tail effects are clustered in the cross-section where average revenue per order is high or the restaurant belongs to the top 50% of the sales distribution. Research implications or Originality - The findings may indicate that digital platforms are contributing to the development of the digital economy in Korea. Also, we confirm that digital platforms make it possible for small and sole proprietors to go through the difficulties induced by the COVID-19 pandemic.

One of the most difficult and time-consuming stages in the development of the knowledge-based system is a knowledge acquisition. A splitting algorithm is developed to infer a rule-tree which can be converted to a rule-typed knowledge. A market segmentation may be performed in order to establish market strategy suitable to each market segment. As the sales data of a product market is probabilistic and noisy, it becomes necessary to prune the rule-tree-at an acceptable level while generating a rule-tree. A splitting algorithm is developed using the pruning measure based on a total amount of information gain and the measure of existing algorithms. A user can easily adjust the size of the resulting rule-tree according to his(her) preferences and problem domains. The algorithm is applied to a market segmentation problem of a medium-large computer market. The algorithm is illustrated step by step with a sales data of a computer market and is analyzed.

After reported that Styrene dimer and Styrene trimer was Endocrine Disrupter, if it was a fact or not, the sales of PSP noodle cup was rapidly decreased and social responsibilities of the substitution materials development was raised. Therefore we had studied many materials like paper, pulp mold, PP injection molding, PP lamination, etc as substitution materials and selected paper cup which was safe in many sides and easy to recycle. Mainly we had checked the shape, safety, stability and recycling possibility of paper cup and secured many data which could prove them.

사회가 고령화, 초핵가족화 및 재난취약계층이 늘어나면서 요구호자에 대한 고품질 맞춤형서비스가 필요하게 되었고, 급성진환, 심뇌혈관 고위험 환자 및 자살 등 예방가능 사망률이 선진국에 비해 높음에 따라 신속하고 전문적인 구조 구급서비스가 요구된다. 따라서 본 논문에서는 응급환자가 발생하였을 때 병원 도착 전 환자의 정보를 이용하여 응급처치가 가능하도록 하고, 응급의료기관에서는 환자 진료준비를 사전에 할 수 갖출 수 있도록 하여 응급환자 진료의 효율성을 극대화하였다. 또한 사회적 인지도가 높은 119번호를 이용한 다양한 복합 응급신고 접수 시 유관기관과 통합적 대응체계를 구축하는 효율적 응급의료서비스 고도화 전략을 제시하고자 한다.

Objectives: Promotion of food safety/eradicating adulterated food has been listed as one of the four major issues recently identified for action by the Korean government. Due to the related seriousness, the food industry has been encouraged to take steps to restore consumer confidence. In order to set guidelines for the creation of manuals for the response to a food safety crisis by the food industry, this study provided a suggested organization for a crisis response team and operating procedures for crisis response activities. Methods: The prototypes of an organizational structure and a set of standard procedures for a crisis response system were provided. Results: The results of the study suggested that a crisis response team should be comprised of four divisions of responsibility: information analysis, site response, communication and operational support. The organization chart and the role and functions for each division of the crisis response team should be indicated. Response activities will be more effective when the team features multi-disciplined staffing, such as public relations, food safety/technology/quality, sales/marketing, purchasing, production, distribution/logistics, regulatory affairs/legal, and consumer service specialists. This study created a flow chart for the total crisis response system, which included crisis and normal situations. A crisis response team should be continuously operated for both crisis and normal conditions. This study also suggested a scenario to explain the procedures for crisis response activities. Conclusion: In order to cope more effectively with a food safety crisis, the organizational structure and its functions should be defined clearly, and a detailed set of standard procedures for response activities should be offered.

상용(Commercial type) 냉각 팬이 적용된 방산용 전자장비는 생산 기간 중 팬 단종이 빈번하게 발생된다. 팬 단종 문제의 해결을 위해서는 대체 팬 선정이 필요하며, 고온 동작 시험 등의 장비 성능 및 신뢰성 검증이 요구된다. 따라서 본 논문에서는 생산 과정에서 활용 가능한 효과적인 대체 팬 선정 및 검증 방안에 대해 연구하였다. 먼저, 장비 냉각에 필요한 유량 및 압력을 계산하여 대체 팬을 선정하였고, 신뢰성을 확보한 CFD 방열 해석 모델을 활용해 팬 선정의 타당성을 검증하였다. 이후 대체 팬을 장비에 적용하여 고온 운용 시험을 수행하였다. 그 결과 장비는 고온 환경에서 정상적인 기능을 발휘하였으며, 주요 부품 및 내부 공기 온도는 열적으로 안정된 상태임을 확인하였다.

Purpose: This paper has examined the impact of open innovation business model in technology commercialization with the data from 30 companies of manufacturing firms in South Korea. Methods: The findings provide support for distinguishing five hypotheses relating to development time, IP management, sales, firm size and R&D intensity. To test the hypotheses, data were collected using via e-mail and fax. Small and medium-sized (less than 300 employees) and large industrial firms were chosen for this study. Results: The result shows that openness in its business model is positively associated with successful technology commercialization. Conclusion: The major findings and the implications are: First, as the business model gets more open, development period of technology will be more favorable which gets benefit from rising costs of innovation. Second, as the business model gets more open, large portion of sales are created from new products. Thus, the problem of shorter product life in the market which affects large portion of market revenue can be solved through an open business model. Third, in general, R&D intensity, firm size and the level of IP management affect determination of business model types. The findings also suggest that companies need to increasingly address their external technology exploitation process instead of focusing on their internal innovation processes.
