This paper examines critical successful elements related to the management of new product development process. For this, we have selected a VK-X100, slim bar type cellular phone, produced by VK mobile co., which was thought as a successful product development case and then analysed the case from a concept driven strategic product development's point of view. We have performed in-depth interviews with project managers, engineers and designers to get information on the product development process and analysed huge amount of data obtained from web-sites, global market indicators, and related firms' materials to find a changing trend of market conditions. The findings suggest that the successful new Product development and management is shaped by a number of different factors, such as the business environments, firm's technological level, firm's deep market insight capabilities, nature of the product development activities, and so on. Finally, we suggested the limitation of our research and further research subjects that would be required to support our findings.

A look back at the history of war reveals that leaders/nations which were able to recognize beforehand the change in weaponary or the concept of implementing war achieved victory in war(battle) while those that were not able to do so lost. Along with the development of civilization, so too did the characteristics of war : from the first wave of war (ancient, Napoleon's war)$\rightarrow$ the second wave of war (The first and second World War) $\rightarrow$ to the third wave of war (The Gulf War, and the War in Iraq). Especially notable was the American led victory earned in the Afghanistan and Iraq wars which applied the Rapid Decisive Operations(RDO) concept according to the Effects Based Operations(EBO) following the Gulf War and 9.11. This is the time when methods of warfare is changing through development in military science technology and military innovation and when the change of the defense paradigm including those of the Korea - U.S. alliance is required. We should therefore prepare for the future by delving into the analysis of American Modern warfare and learn from it.

Using the concept of a piecewise linear function, we present new operations for fuzzy arithmetic and then compare the operation based by the extension principle with the new operation.

Action learning motivates students to solve open-ended problems by 'developing skills through doing'. This paper reviews the concept of action learning and discusses the adoption of action learning approach to teach operations management at universities. It presents the design and delivery of an action-learning course at City University of Hong Kong. The course incorporates classroom lectures, tutorials and an action-learning workshop. The experience gained proves that action learning facilitates student participation and teamwork and provides a venue of accelerating learning where enables students to handle dynamic problem situations more effectively. The paper concludes that adopting action-learning approach can help lecturers to enhance quality teaching in operations management courses, and provide an alternate means of effective paradigm other than traditional classroom teaching and/or computer-based training at universities.

The time components of the operations were investigated on the rice paddy field operations by radio controlled helicopter. The net time of operations, seeding and application, were less than a quarter of the required total time in the field of 1 ha. The most interesting is how to decrease the time of hop-off and landing. In this paper the seeding density itself is taken under a new look and its describing method is discussed. Voronoi diagram was introduced to consider individual plant of rice paddy. Extremely wide ranges of the distribution of seeding density are not supposed by the common indexes based on the concept of mean values and discussed on the aggregate of plants.

The purpose of this study is to re-concept the future battle of the Army, which combines the effects of advanced technology on the concept of combat and the AICBM technology. The "war concept" changes with the times, and can be seen through the following two examples. First, it is a concept that achieves relative superiority by analyzing enemies. A case in point is the U.S. military's development of a "public joint battle" into a "multi-domain operation." Second, it is 'science and technology' that leads to a change in the concept of combat. A case in point is that the firepower warfare on land and sea in World War I developed from World War II to "air warfare" due to the emergence of aircraft. In this regard, the U.S. military is focusing on the concept of fighting in line with the future operational environment based on high-tech science and technology and the construction of the future military through the creation of the "Future Command." Therefore, our military needs to utilize the major technologies of the fourth industrial revolution as an opportunity to develop the concept of future combat, and the future war will greatly affect the development of the concept of advanced science and technology carrying out war, as AIC technology based on the fourth industrial revolution will promote innovation in defense operations in the form of super-connected, super-intelligence and super-integration. Therefore, this study will present the impact of advanced technology on the concept of combat and the concept of battle of the future Army incorporating the technology of AICBM.

In this paper, for the systematic software evaluation and selection objective, we first discussed the systems software which is distinctly different from applications oriented software in source, concept and use. We suggested the systematic procedures for the effective software evaluation and selection by analyzing categories of commercially available proprietary software, sources of information for software selection, request for information, request for proposal, user surveys as an aid to evaluation and evaluation of responses to the RFP.

Both browsing and retrieval with search engines are major operations that establish the interaction between users and the Web. Although both operations are usually combined to locate information from the Web, recent growth of the Web has overtaken the potential of this conventional interaction. This paper proposes the concept of Retrieve, Browse, and Analyze (RBA)-based interactions, as the improvement of the conventional Retrieve and Browse (RB)-based interaction. The prototype interface based on RBA-based interaction is also presented.

In the light of globalisation and the international division of labour, the article will stress the importance of a new conception of quality management, focusing more on the social and environmental aspects of quality in global supply chains with a particular emphasis on suppliers' perspectives. The increasing focus on corporate social responsibility, business ethics, corporate citizenship, sustainable development etc. indicates that managers have failed to see social and environmental aspects of the production as an integrated part of quality.

An optimal allocation model for SAM-X by using a set covering model is suggested. This allocation model considers to guarantee the maximum security of vital areas from the attack of enemy aircraft(s) and missiles. In order to formulate this model, we applied the concept of parallel structure reliability to set covering model. This model gives both direction of the primary target line and location of the facility. When applied this model to the real situation, the solution of this model can be used to the references of decision making for the optimal military facility allocation.
