The purpose of this study is to explore the applicability of QFD to product development of clothes by empirically applying it to development of a specific clothes, middle and elderly women’s formal knitwear. The voices of customers(VOCs) for formal knitwear was collected through in-depth interviews with 25 customers, shop masters, and designers. Also, questionnaires of which respondents were 230 customers were used to rank the importance of the items of VOC. A QFD team of 10 knitwear experts implemented the task of translating VOCs into design attributes and measuring the values of the relationships between VOCs and design attributes. Importance ranking of the items of design attributes was obtained based on Lyman's method. The results of this study were as follows. First, the customer requirements for formal knitwear were classified into five dimensions, that is, symbolism, aesthetic, fitness, usefulness, and maintenance. Second, the descending order of the necessity of improving the quality was maintenance, aesthetic, fitness, usefulness, and symbolism. Third, three-staged design attributes were obtained as a result of translating of VOCs into design attributes. Lastly, the descending order of the importance of design attributes was "sorts of yarn", "sorts of color jacquard", "color", "tone", "ease", etc.

The necessity of estimating the time and cost required for tunnel construction has led to extensive research in this regard. Since geological conditions are significant factors in terms of time and cost of road tunnels, considering these conditions is crucial. Uncertainties about the geological conditions of a tunnel alignment cause difficulties in planning ahead of the required construction time and costs. In this paper, the continuous-space, discrete-state Markov process has been used to predict geological conditions. The Monte-Carlo (MC) simulation (MCS) method is employed to estimate the construction time and costs of a road tunnel project using the input data obtained from six tunneling expert questionnaires. In the first case, the input data obtained from each expert are individually considered and in the second case, they are simultaneously considered. Finally, a comparison of these two modes based on the technique presented in this article suggests considering views of several experts simultaneously to reduce uncertainties and ensure the results obtained for geological conditions and the construction time and costs.

In this paper, we identify and evaluate the information security factors considered in outsourcing development of information systems for defense agency with analytic hierarchy process(AHP). To assess the information security elements, we prepared three groups including the experts of a defense agency, subcontractor managers and subcontractor practitioners who are involved in developing information systems. And the relative importance of security factors were analyzed using questionnaires and responses. As a result of analysis of 27 security factors, factors corresponding to human and physical security as a whole were evaluated as having higher importance. Although there are some differences in the ranking of some importance according to human roles, they can be positive for the implementation of complementary information security. And administrative security and technical security can be relatively insignificant considering that they can be considered as infrastructure of the overall information environment. The result of this paper will be helpful to recognize the difference of perception of information security factors among the persons in the organization where collaboration is activated and to prepare countermeasures against them.

In this paper, we focused on the safety of workers in a remanufacturing process where a risk analysis is not carried out and suggested a criteria for evaluating injury risk. We analyzed a disassembly and a reassembly, which are important for the remanufacturing process. The disassembly includes the disassembly of product and the disassembly process of part and the reassembly includes only reassembly of part. First of all, we analyzed the remanufacturing process and a type of injury. Then, we reviewed the standards and determined the criteria for a severity and an occurrence. We set a bigger weight for the severity to allow the greater impact. And the injury risk score was defined as a sum of the weighted severity and the weighted occurrence. We conducted a qualitative analysis of the experience of field workers based on the criteria we set up. Questionnaires for the evaluation were formulated through interviews with experts.

Purpose: This study aimed at understanding terminal care provided in nursing homes. Method: An interview survey with staff in charge of terminal care was conducted in 97 nursing homes using questionnaires. The questionnaire was reviewed by 3 experts and pretested at 5 facilities. Data were analyzed using descriptive statistics, chi-square test, and Fisher's exact test. Result: Dyspnea was the most prevalent symptom predicting death. The most prevalent services were vital sign check for physical care, providing services by talking despite an unconscious state for psychosocial care, and respecting the faith of the elder for spiritual care. Employment of a registered nurse showed a significant difference in tube feeding (p=.035), analgesic administration (p=.022), informing the elder of end-of-life state (p=.020), helping an elderly person say good-byes through a visit with friends and acquaintances (p=.023), and helping express feelings related to death (p=.002). Lack of service was noticed for elderly resident, family, and staff after death of an elder. Problems related to terminal care were indifference of family members, difficulty in obtaining medical prescription, difficulty in predicting death, and so forth. Conclusion: Terminal care must be improved by making specific guidelines and it must become a part of nursing home evaluation.
