  • The semiconductor industry is highly capital and technology intensive. Technology advancement on circuit design and process improvement requires chip makers continuously to invest a new fabrication facility that costs more than 3 billion US dollars. Especially major semiconductor companies recently started to discuss 450mm fabrication substituting existing 300mm fabrication of which facilities were initiated to build in 1998. If the plan is consolidated, the yield of 450mm facility would be more than doubled compared to existing 300mm facility. In steps of this important investment, facility layout has been acknowledged as one of the most important factors to be competitive in the market. This research proposes a new concept of semiconductor facility layout using hexagonal floor plan and its compatible material flow pattern. The main objective of this proposal is to improve the productivity of the unified layout that has been popularly used to build existing facilities. In this research, practical characteristics of the semiconductor fabrication are taken into account to develop a new layout alternative based on the analysis of Chung and Tanchoco (2009). The performance of the proposed layout alternative is analyzed using computer simulation and the results show that the new layout alternative outperforms the existing layout alternative, unified layout. However, a few questions on space efficiency to the new alternative were raised in communication with industry practitioners. These questions are left for a future study.

  • Objective : There is a growing interest on Complementary and Alternative Medicine(CAM). But the term 'CAM' often causes confusion, for the perception of CAM is determined by how the relationship between CAM and Conventional Medicine is established. Methods : In this paper, we researched the concept of CAM through the change in the terminology and definition of CAM throughout history. Furthermore, we also analyzed related papers in Korea. Results : International studies show that the relationship between Conventional Medicine and CAM has become more cooperative. Meanwhile, in Korea, Korean Medicine is categorized as a type of Conventional Medicine, not CAM. Conclusion : Though Korean Medicine is included in Conventional Medicine in Korea, the research methodology is still restricted in ways of bio-medical science. Further study on the original research method of Korean Medicine is needed.

  • Dealing with uncertainty is always a challenging problem. Intuitionistic fuzzy sets was presented to manage situations in which experts have some membership and non-membership value to assess an alternative. Hesitant fuzzy sets was used to handle such situations in which experts hesitate between several possible membership values to assess an alternative. In this paper, the concept of intuitionistic hesitant fuzzy set is introduced to provide computational basis to manage the situations in which experts assess an alternative in possible membership values and non-membership values. Distance measure is defined between any two intuitionistic hesitant fuzzy elements. Fuzzy technique for order preference by similarity to ideal solution is developed for intuitionistic hesitant fuzzy set to solve multi-criteria decision making problem in group decision environment. An example is given to illustrate this technique.

  • For the purpose of decreasing economic loss from the traffic jam, a car route guidance system efficiently utilizing the existing roads has attracted a great deal of attention. In this paper, the search algorithm for optimal path and alternative paths, which is the main function of a car route guidance system, was presented using evolution program. Search efficiency was promoted by changing the population size of path individuals in each generation, applying the concept of age and lifetime to path individuals. Through simulation on the virtual road-traffic network consisting of 100 nodes with various turn constraints and traffic volumes, not only the optimal path with the minimal cost was obtained, avoiding turn constraints and traffic congestion, but also alternative paths with similar costs and acceptable difference was acquired, compared with optimal path.

  • In Korea, most of the patients with chronic liver diseases have been using some kind of alternative therapies at home. however, the question is why do people turn to alternative therapy and how the patients are able to use the alternative therapies widely, though the effects have not been proven scientifically. Therefore, it is necessary to explore the process of the patients' experiences using the alternative therapies. The 16 participants were from internalmedical departments in hospital and the permission was received to participate in this study from the subjects. The data were collected with interviews and participants observations, analyzed by the grounded theory methodology of Strauss and Corbin(1990). With the analysis of the data, 15 categories were generated such as psychological pressures, barriers of role performances, distrusts of western medicine, blind obediences to the treatments, attitudes towards alternative therapies, supportive systems, obstacles to taking alternative therapies, financial burdens, collecting informations, pursuing alternative modalities, efforting diversities, analyzing by themselves, managing the body, accepting the disease, and ambivalence. The paradigm model was developed to identify the relationships of categories. The central phenomenon of the experiences of seeking alternative therapies was named jagi momdasrim. The central concept of jagi momdasrim is a mind-set to desire to wellness and to take more responsibility for one's own healing by pursuing alternate healing modalities rather than the western medical system. The process of jagi momdasrim evolved several stages such as seeking, finding, struggling, overcoming, fulfilling, and governing the diseases. Four patterns of taking alternative therapies were found as follows: the bulsin-chujong-hyung, the suyoung-hyung, the yangdari-gulchiki-hyung, the chamjae-hyung. In conclusion, the phenomenon of alternative therapies as consumer-driven force to heal the chronic liver diseases of the patients could be explained as an adaptive behavior through the process of jagi momdasrim. However, since most of the participants practicing some kind of alternative therapies had no evidences of its effects and never tried to consult with their medical doctors about alternative therapies, we should approach more actively. Therefore, it is recommended for nurses to listen and watch the patients behaviors of using alternative therapies and find out how to educate the patients about the proper and safe way to take the alternative therapies.
