This study examines the persistent decline of the motorcycle industry despite governmental interventions, using the perspective of path dependency. Drawing from W. B. Arthur's concept of 'Lock-in by insignificant historical events', the research delves into the lock-in phenomena within the industry's life cycle. We identified path dependency lock-in categories: contingency, historicity, and technological lock-in. The industry's licensing production method during its embryonic phase led to limited technological capabilities, establishing a technological path dependency. During the currency crisis and in alignment with China's open-door policy, the industry chose to import cheaper components, opting for economies of scale over technological innovation, intensifying the lock-in. Furthermore, the classification of motorcycle as a free industry before the currency crisis resulted in a lack of governmental support. This neglect has continued, with even modern electric motorcycle facing regulation. In conclusion, to overcome this entrenched path dependency and lock-in, significant governmental policy restructuring is essential.

In the context of the 4th Industrial Revolution, the rise of electric vehicles and personal mobility is evident. However, regulatory authorities seem to overlook vast opportunities, placing two-wheelers in a deregulated category and focusing mainly on regulations. This paper addresses a notable trend in e-mobility, emphasizing aspects often overlooked in traditional motorcycle regulatory research. Using the industrial life cycle theory as a basis, we identify challenges that have affected traditional combustion-engine two-wheelers and offer insights to navigate similar obstacles in the future. Consequently, the domestic two-wheeler market experienced a brief surge but lacked sustainable growth prospects. However, considering Japan's success in establishing global standards and design dominance in the two-wheeler industry despite its late entry, there appears to be potential for a rebound in the domestic market.

This research studies on the demand forecasting for service parts considering parts life cycle, that gets relatively less attentions in the field of forecasting. Our goal is to develop forecasting method robust across many situations, not necessarily optimal for a limited number of specific situations. For this purpose, we first extensively analyze the drawbacks of the existing forecasting methods, then we propose the new demand forecasting method by using these findings and reinforcement leaning technique. Using simulation experiments, we proved that the proposed forecasting method is better than the existing methods under various experimental environments.

The enterprise life cycle derived from the product life cycle consists of introduction, growth, maturity and decline. The enterprise tries to reach the growth stage early and stay at the maturity stage stably through expanding its businesses and investing for the new technology. The public enterprise is not different but its life cycle is more prone to be affected by the national development and policy. A typical example can be found in the case of the quasi market SOC public enterprise which spends massive amount of fund to provide social infrastructure. After the fulfillment of its mandated mission it is exposed to the pressure of a merger or a closure usually because large portion of the debt is directly linked to the national financial stability and credit ratings. This research is focused on the variables that influence the life cycle of the quasi market SOC public Enterprise for its future competitiveness is in connection with its normalization, advancement and rationalization. In this respect, categorical variables system centering on public characteristics and profitability drew eight categorical variables such as policy outcomes, public benefit, finance and business values etc.

Internet of Thing(IoT), which is recently talked about with the development of information and communication technology, provides big data to all nodes such as companies and homes, means of transportation etc. by connecting all things with all people through the integrated global network and connecting all actual aspects of economic and social life with Internet of Thing through sensor and software. Defining Internet of Thing, it plays the role of a connector of providing various information required for the decision-making of companies in the cloud computing environment for the Insight usage by collecting and storing Raw Data of the production site through the sensor network and extracting big data in which data is accumulated and Insight through this. In addition, as the industry showing the largest linkage with other root industries among root industries, the mold industry is the core technology for controlling the quality and performance of the final product and realizing the commercialization of new industry such as new growth power industry etc. Recently, awareness on the mold industry is changing from the structure of being labor-intensive, relying on the experience of production workers and repeating modification without the concept of cost to technology-intensive, digitization, high intellectualization due to technology combination according to IT convergence. This study, therefore, is to provide a golden opportunity to increase the direct and indirect expected effects in poor management activities of small businesses by actually implementing and managing the entire process of mold life cycle to information system from mold planning to mass production and preservation by building SME(small and medium-sized enterprises)-type mold life cycle management information system in the cloud computing environment and applying it to the production site.

본 연구는 규모가 작고 역동적인 벤처기업의 성장에 영향을 줄 수 있는 요인들 중에서 기업의 전략적 행동이나 경영자의 경영 역량과 관련된 제품 전략과 CEO(최고경영자) 특성의 효과를 실증적으로 분석하였다. 벤처기업의 표본을 이용하여 FGLS 추정법에 기반한 회귀분석의 결과에 따르면, 제품 전략과 CEO 특성은 기업 성장에 유의한 영향을 주며 추가적인 설명력을 가진다. 일반적으로 제품의 다양화와 마케팅을 강조할수록, 변화혁신을 완화할수록 성장률이 높았다. 그리고 CEO가 경영지배력을 가진 창업자가 아니거나, 현재 사업관련 분야에서 실무경험이 많을수록 성장률이 높았다. 또한, 연구개발 위주 업무경력보다 일반경영 중심의 업무경력을 가진 CEO가 관리하는 기업이 성장률이 더 높았다. 제품 전략과 CEO 특성이 벤처기업의 성장에 미치는 이런 효과들은 조직수명주기 단계에 따라서 달라졌다. 창업기 및 초기 성장기에 있는 기업에서 제품의 마케팅 강조 전략과 CEO의 일반경영 중심 업무경력이 기업 성장에 미치는 긍정적 효과가 상대적으로 강화된 반면, 성숙기 및 정체기에 있는 기업에서 이런 제품 전략과 CEO 특성이 기업 성장에 미치는 효과가 부정적이거나 유의하지 않았다.

This study investigated the life cycle of menus and made suggestions on the appropriate time for when new menus should be developed. For this purpose, a total of 636 customers who visited ‘T’ Restaurant more than 25 times in the past three years were used for analysis. After estimating product life cycles based on sales and selling period, an empirical study was conducted. In terms of product life cycle, a growth stage was observed in the category of pasta and pizza in both stores A and B, whereas sales in the rice category stayed constant. Regarding trend in seasonal sales, a big difference was detected between the two stores. While store A was already in the decline stage of the life cycle in all menu categories, store B remained in the growth stage. In terms of menu life cycle, the product life cycle of long-lived products was observed in the pasta category in both stores A and B. While the pizza category was in the growth stage, the product life cycle of long-lived products was observed in the rice category. It is expected that the results of this study could be useful in development of new menus and product life cycle management to fulfill diverse customer needs in the dining-out business.

Survival and development of manufacturing business depends on how the companies make competitive product and put out on the market. In other words, the core competitiveness of manufacturing business is "product" and companies’ competitiveness and sustainable growth could be guaranteed by management from product deveIopment to release onto the market. However, there are few examples about establishing successful system yet. The purpose of this study is to analyze on how PLM affect the performance. In particular, findout how iIlegal copying of PLM system that contains know-how gives company negative effect and emphasize why companies should recognize the importance of iIIegaI copying.

The Cost has been much emphasized in inside of an army because of the promotion of reconciliation atmosphere between South and North Korea and the reduction of defense budget since 1990. So we are now faced with the problem that we should consider a cost above all besides the performance and arrangement for such a restriction of budget in time of developing new generation weapon systems. In this research we are suggested following two methodologies. One is the develop a weapon system with optimum cost considering a Life Cycle Cost from the first stage of design and the other is the cost control and management with the establishment of Target cost.

구조 형식이나 공법의 선정, 유지보수 시기, 보수방법의 결정 등의 의사 결정에서 수명주기비용(life cycle cost, LCC)의 평가가 중요 하다. 철도 궤도구조의 경우 초기시공비 뿐 아니라 유지보수비가 총 비용의 상당 부분을 차지하고, 특히 자갈궤도일수록 그 비율은 더욱 높으 므로 수명주기비용 평가의 필요성이 더욱 높다. 이 연구에서는 궤도 구조 형식, 연간 통행량, 축중, 열차 속도, 곡선 비율, 구조물(교량, 터널) 비 율 등 다양한 설계변수를 고려할 수 있는 LCC 산정 모델을 개발하고, 각 비용의 산정에 필요한 기초 자료를 제시하였으며 구축된 모델과 자료 를 바탕으로 주요 설계변수에 따른 고속철도 자갈궤도와 콘크리트궤도 LCC의 변화 경향을 분석하고, 이로부터 궤도 LCC 분석에 있어서의 고 려해야 할 주요 변수를 검토하였다. 검토 결과 자갈궤도는 교체 및 운영 비용의 비중이 콘크리트궤도에 비해 현저히 높았으며, 연간 통행량과 자갈 탬핑 주기가 자갈궤도의 LCC에 가장 큰 영향을 미치는 것으로 나타났다. 반면 콘크리트궤도는 초기 시공비의 비중이 현저히 높았고, 연 간 통행량이나 열차속도, 축중 등에 상대적으로 영향을 적게 받는 것으로 나타났다.
