Safety of workers and productivity in construction site are affected according to the conflict status of work spaces which are performed at a time. The interference among the work spaces in construction site should be minimized because it becomes a blocking factor that causes construction delay and low productivity. Those factors can be managed by reasonable H&S (Health & Safety) practice. This research suggests the requirements of H&S practice and rules to establish the strategy of H&S management based on the literature reviews related to H&S rule. The suggested H&S rule can be visualized for searching space conflict point if the rule is linked with visual simulation tool. Accordingly the research results can be used for improving and visualizing construction productivity by work space control in 4D/nD CAD system.

신뢰는 인간관계에서 동서고금을 통해 언제나 주목을 받아온 주제였으며, 신뢰의 중요성은 경영학 분야는 물론 인간생활의 모든 분야에서 이미 오랜 전부터 인식되어 왔다. 그러나 대부분의 연구는 주로 개인 간의 신뢰인 종업원에 대한 신뢰에만 집중하는 단일 차원적 관점에서 연구되어 왔다. 본 연구는 이와 같이 지금까지 주로 단일차원으로 연구되어 온 신뢰 대상을 판매원, 제품/서비스, 그리고 기업의 3차원으로 다차원화하여 이들 신뢰 대상이 재구매 의도에 미치는 영향을 검증하였다. 서울, 대구 경북지역의 거주자로 백화점에서 구매 경험이 있는 남녀 고객을 대상으로 수집된 자료를 분석한 결과, 기존 연구들에서 주로 다루어진 판매원신뢰뿐만 아니라 기업신뢰와 제품/서비스신뢰 또한 고객신뢰의 중요한 대상으로 나타나, 신뢰 대상은 다차원적인 구성개념임이 밝혀졌다. 이들 3차원의 신뢰는 모두 재구매 의도에 유의한 영향을 미치는 것으로 나타났으며, 특히 기업신뢰가 판매원신뢰와 제품/서비스신뢰보다 재구매 의도에 더 영향을 미치는 것으로 나타났다. 판매원신뢰와 제품/서비스신뢰의 영향요인으로 역량과 선의를, 기업신뢰의 영향요인으로 기업 평판과 물리적 환경을 설정하여 검증한 결과 역량과 선의는 판매원신뢰와 제품/서비스신뢰 모두에 유의한 영향을 미치는 것으로 나타났다. 기업신뢰의 경우, 평판은 유의한 영향을 미치는 것으로 나타났으나, 물리적환경은 유의한 영향을 미치지 않은 것으로 나타났다.

Purpose - Focusing on Haier, a successful corporate venture in China, we analyse the operating mechanism and success factors of corporate venture, and reveal the necessary factors for the successful implementation of corporate venture. Design/methodology/approach - This study is a single case study centred on Haier, a successful corporate venture in China. Findings - The operational process of Haier's corporate venture includes six key aspects: project selection, team building, resource allocation and support, project implementation, risk control measures, performance evaluation and rewards. In terms of success factors, the support of top management with leadership capability of value creation and sharing is very important for the success of corporate venture. Secondly, a multi reward mechanism can be introduced to motivate employees and improve performance. Thirdly, it is important to integrate corporate culture into the operating mechanism of an corporate venture. Fourthly, flexible operations that break down rigid organisational boundaries and transform the organisation into a more open platform for entrepreneurship can increase the likelihood of success. Finally, empowering employees with operational discretion can also have a positive impact on the success of an Corporate Venture. Research implications or Originality - This study contributes to theory and practice by analysing the success conditions of corporate venture, providing new understanding and drawing new perspectives, especially from the experience of Haier. The results suggest strategies and flexibility for successfully pursuing corporate venture, and provide important experience for international companies to help them gain competitive advantage in global competition. It also helps corporate leaders to promote new directions and innovations and improve their strategies to respond to dynamic environments.

본 연구는 국내 대표적인 지역사회공헌프로그램인 1사1촌 자매결연 활동에 참여하고 있는 기업들을 대상으로 자매결연의 교류현황을 살펴보고, 1사1촌 자매결연활동을 주관하는 중간지원조직으로서의 농촌사랑국민운동본부의 기능을 평가하였다. 분석결과, 기업은 농촌 지역의 어려움을 인식하고 개선시키기 위한 목적으로 1사1촌 활동을 전개하고 있었으며, 일손돕기와 같은 단순교류 활동이나 농산물 직거래 활동이 주요 교류활동으로 나타났다. 농촌사랑국민운동본부의 역할에 대한평가는 자매결연 초기에 필요한 정보제공 및 중개기능이 높게 평가되었으며, 결연 이후 지속적인 참여를 유도하기 위한 네트워크 및 교류촉진 기능은 낮게 평가되었다. 향후 1사1촌 자매결연 운동이 보다 실질적인 지역사회투자활동으로서 발전하기 위해서는 농촌마을과 기업의 중개 및 중재기능을 보완하고 마을과 기업의 특성에 맞는 맞춤형 프로그램의 개발이 요구되는 바이다. 또한 기업 및 농산촌 마을 이해관계자들을 대상으로 협의회를 구축하고 학습 및 교류 기회를 제공하여 정보를 공유하고 네트워크를 구축할 수 있는 기회를 증진시켜야 할 것이다. 이밖에 농촌의 사회, 경제 문화, 환경의 다각적인 접근을 통해 농촌지역 문제를 해결할 수 있는 실용적인 솔루션을 개발하여 지역경제활성화 및 고용창출의 효과를 극대화시켜야 할 것이다.

In this paper, a two-mass system for SiOG (Silicon on Glass) vibratory gyroscope with the need of frequency tuning was proposed to increase the stability of the device with wide bandwidth. Air damping and bandwidth were analyzed using MATLAB. The measured resonance frequency is 5.2 kHz, which is 7 kHz in the design. But the measured bandwidth is 450 Hz, similar to the designed bandwidth with 500 Hz. Also the frequency difference (210 Hz) between the driving and sensing part is smaller than the wide bandwidth of two mass system.

Today, as technology advances and market competition for products intensifies, the product design to improve customer satisfaction by accurately identifying customer needs is emerging as a very important issue for company. Accordingly, the customer-oriented or customer-centered design that maximizes customer satisfaction by grasping and analyzing customer requirements is in the spotlight as an important design theory. In this study, the customer-oriented design is defined as finding the optimal value of design variable with the maximum overall customer satisfaction while minimizing the difference in individual customer satisfaction responded to various customers from multiple product quality characteristics from the perspective of robust design. Therefore, this study presents a new method for modeling the customer preference structure as the different sets of desirability functions for multiple quality characteristics and proposes a new customer-oriented design approach by applying the desirability functions to Taguchi's robust design process to deal with multi-characteristic design problem. Finally, the proposed method is illustrated with the Kansei engineering design problem of wine glass.

The percentage of 3PL (Third-party Logistics), which uses third party businesses to outsource elements of the company's distribution and fulfillment services, is increasing steadily. To provide 3PL service to the customers, it is needed to estimate the total transportation cost and propose the unit cost to the customers. In this paper, we develop a decision support system for estimation of transportation cost of 3PL provider considering various transportation services, such as direct transportation, multi point visiting transportation, and cross docking. The system supports route planning of vehicles by using algorithms based on tabu search and dynamic programming.

A competitive generating company (GENCO) could maximize its payoff by optimizing its generation assets. This paper considers the GENCO's arbitrage problem using price-based unit commitment (PBUC). The GENCO could consider arbitrage opportunities in purchases from qualifying facilities (QFs) as well as simultaneous trades with spots markets for energy, ancillary services, emission, and fuel. Given forecasted hourly market prices for each market, the GENCO's generating asset arbitrage problem is formulated as a mixed integer program (MIP) and solved by a branch-and-cut algorithm. A GENCO with 54 thermal and 12 combined-cycle units is considered for analyzing the proposed formulation. The proposed case studies illustrate the significance of simultaneous arbitrage by applying PBUC to multi-commodity markets.

Vehicle stability is a very important subject in vehicle design and control, because vehicle safety is closely dependent upon its dynamic stability. The control logic for four-wheel steering(4WS) systems, in which maintaining at least the specified stability region is the control objective, was constructed using the simplified vehicle model of 3 degree-of-freedoms. The improvement of vehicle stability was verified through computer simulations for the slalom and the double lane change maneuver using the multi-body dynamic model in MSC.ADAMS.

ABC analysis is the process of dividing inventory items into three classes according to their monetary usage so that managers can focus on items that have the highest monetary usage value, and has been widely used in practice since its development in 1950. However, the original criterion, monetary usage value, can no longer be the only rational criterion. Applying Analytic Hierarchy Process, we develop a new method to classify inventory items by considering such operationally/strategically important criteria as annual dollar usage, lead time, supplier's capacity, defective rate, difficulty of purchasing and unit price. A case study is performed applying the method to the field data from a company which produces electrochemical products.
