ISO9000 set of standards has been widely applied in Iranian Automotive manufacturing industry. Regarding the effects of TQM and ISO9000 set of standards various studies have been conducted and different quantitative conclusions have been made. Due to lack of quantitative information, in many of the cases, using qualitative information becomes the best option. The qualitative nature of data in such cases, requires qualitative analysis methods that might lead to some challenging computational issues. This paper examines the impact of ISO9000: 2000 certification and its perceived benefits for an automotive manufacturing company. Using an empirical approach, the paper seeks to ascertain if certification has indeed improved the performance of the company. Our null hypothesis rotates around the effect of ISO9000: 2000 on the 4W's of an enterprise. To carry out the research, first we developed a couple of questionnaires including all criteria of ISO9000 and 4W's. Second, the questionnaires were discussed with two researchers knowledgeable in the field, and then submitted to the quality practitioners and executives of Iran Khodro Enterprise-a leading company in Iranian automotive manufacturing industry. Finally the null hypothesis was tested and the technology improvement dimensions were ranked through nonparametric tests. The results illustrated a reasonable cause and effect relationship, suggesting that ISO9000: 2000 has positive effect on the 4W's of company result. In this work we investigate the effect as technology improvement viz., the improvement of techno-ware, human-ware, info-ware, and organ-ware.

본 논문은 친환경 연료 중 하나인 수소 원료를 바탕으로 미래의 에너지 문제와 공해 문제를 해결할 수 있는 수소연료전지 기술 도메인에 대해 특허 분석을 실시했다. 특허분석은 현재 기술 수준과 미래 발전 방향을 발견할 수 있어 기술로드맵 수립에 많이 활용된다. 그러나 기존의 특허분석은 정성적인 분석 및 간단한 통계분석으로 현재의 기술 환경을 반영하지 않은 분석 결과를 제안할 수 없다. 현재의 기술 환경은 기술의 융복합으로 발전을 나타내고 있고, 발전 속도는 매우 가파르게 성장하여 정성적인 분석은 시대적 분석 요건에 옳지 않다. 그래서 본 논문은 현재의 기술환경을 반영한 지식상속성(Knowledge Persistence, KP) 기반의 주경로 분석과 텍스트마이닝 방법을 활용하여, 수소연로전지 기술도메인에서 핵심특허 발견, 중요 기술 발전, 유망기술을 조망한다.

This study was conducted to understand and to compare the qualitative aspects of anatomical characteristics in compression wood (CW), lateral wood (LW), and opposite wood (OW) in a stem of Ginkgo biloba. The qualitative analysis was examined by optical microscopy and scanning electron microscopy. CW in Ginkgo biloba disks were dark brown in color, and the OW and LW were light brown in color. CW and OW showed abrupt transitions from earlywood to latewood, while LW showed a gradual transition. Cross sections of CW presented circular tracheids with angular outlines, many intercellular spaces, and varying sizes of lumens. Cross sections of LW and OW showed rectangular tracheids, fewer intercellular spaces, and varying sizes of lumens. In radial sections, CW showed an irregular arrangement of tracheids in earlywood, while LW and OW showed comparatively regular arrangements. Slit-like bordered pits on the tracheid cell wall, piceoid pits in the crossfield, and a few spiral checks were present in CW. LW and OW showed bordered pits with slightly oval-shaped apertures, as well as cuppresoid pits in the crossfields. Rays were primarily uniseriate, with few biseriate rays in the tangential sections of CW, LW, and OW. The tips of the tracheids were branched in CW but had a normal appearance in LW and OW.

The prevention of safety accidents can be achieved through Harvey's 3E's: Engineering, Enforcement, and Education. On construction sites, however, enforcement and engineering did not prove to be valid ways of reducing the number of safety accidents, as enforcement and engineering have failed to overcome and/or supplement the realistic limits regarding the relatively lower education levels of construction workers and the communication issues with foreign workers. On the other hand, safety education can enable the advancement of safety management by enhancing the educational contents and their methods of delivery. To improve the efficiency of safety education via educational contents, this research conducted a qualitative and quantitative analysis on the validity of the newly educational contents by overviewing possible accident types in different work phases. Of the accident types identified by the qualitative analysis, neither highly important nor insignificant accident types were found, yet all the suggested types are found to be required. In addition, this study did not find any significant differences in the occurrence probability of safety accidents related to the level of importance of each type of accident. The qualitative analysis in this research verified that the suggested accident types can be valid, educational material that can take into account future safety accidents.

As many organizations have adopted and implemented ERP systems, concerns about ERP performance also have increased. Former researches studied the ERP implementation of general large or medium size enterprises but there are not enough studies on ERP systems of a specific industry domain. In this paper, we introduce a case study on ERP adoption methodology of global leading company 'D' in shipbuilding and marine engineering industry. We examined ERP implementation background, method and scope and evaluated ERP performance in perspective of both quantitative and qualitative approaches. Quantitative research usually examines ERP performance based on financial statements and qualitative study typically examines organization change or improvement. As a result, ERP implementation in shipbuilding and marine industry can improve quantitative aspects such as cost, human resource and organization performance. As qualitative analysis, business process and tools can be unified and management transparency can be improved by ERP implementation. The result of this paper will be useful guideline for organizations which are considering ERP systems.

The purpose of this research is to describe the experiences of transfer students in nursing colleges. This study was based on the qualitative content analysis. To collect qualitative data, 10 personal interviews were conducted from June 2013 to September 2014. Five sub-themes emerged from the data as follows: Participants started new challenge with self-confidence; Nursing science was difficult and unfamiliar disciplines to them; Firstly, they had no place in nursing department, but got places of their own over time; They managed to hold their own in confronting with difficulties; They consequently made personal upgrades in their life. The results of this study could guide nursing faculties to understand what kind of burdens transfer students experienced, how they had adapted to them, and how to support them to realize their full potential to grow into competent nurses.
