현재 많은 제품 개발이 기존 제품 또는 서비스에 새로운 형상과 기능을 추가하는 컨버전스를 통해 이루어지고 있다. 그러나 제품 개발에서 컨버전스는 제품사용에 대한 긍/부정적 효과를 동시에 유발하며 나아가 소위 "기술의 패러독스" 문제를 내포하고 있다. 한편으로는 기능성 또는 형상의 추가를 통해 제품의 유용성을 향상시키지만 다른 한편으로는 제품 사용 및 사용을 학습의 복잡성을 증가시켜 사용자의 제품에 대한 만족과 서비스 평가에 부정적 영향을 줄 수 있기 때문이다. 이러한 관점에서 본 연구는 대표적 컨버전스 서비스 사례인 텔레매틱스 서비스를 대상으로 이러한 역설의 문제를 탐색한 실증적 결과를 제시하고 있다. 따라서 본 연구의 모델은 "기능다양성", "사용복잡성", "인지된 유용성", "서비스평가", "서비스적합성"과 같은 변인을 채택하여 기술의 역설의 존재를 검증할 수 있도록 설계되었다. 제안된 연구모델과 이에 따른 가설은 실제 텔레매틱스 서비스 사용자 149명으로부터 자료를 수집하여 PLS를 이용한 경로모형분석을 통해 검증되었다. 연구 결과 첫째, 기능다양성의 증가는 인지된 유용성과는 정의 관계가 있으나 사용복잡성과는 부의 관계에 있음이 확인되었다. 둘째, 사용자의 서비스 평가에 대한 영향은 인지된 유용성이 사용복잡성에 비해 더 큰 영향을 미치는 것으로 확인되었다. 마지막으로 연구 결과 1, 2의 변인 간 인과관계의 강도가 서비스 적합성에 의해 부분 조절되는 현상을 확인하였다. 이러한 연구결과는 컨버전스 서비스와 관련된 사용자의 믿음, 태도를 설명함에 있어서 기술의 역설의 영향을 강조하고 있다.

The purpose of this descriptive study was to identify problems and solving strategies on student evaluation of clinical nursing education. Subjects were 239 nurses in 18 hospitals from February to July, 1999. Content analysis using qualitative research method was used to analyze data taking into account the semi-structured questionnaire. The results of this study were as follows: Four categories about problems and solving strategies on the evaluation of clinical nursing education were identified: 'The environment of the clinical nursing education'; 'contents and items of evaluation tool'; 'criteria of evaluation tool'; and 'problems with evaluators in clinical settings'. The problems of the environment of the clinical nursing education were due to the lack of co-ordination between nursing schools and hospitals. In order to solve these problems, the following strategies were suggested: 'initiate a joint meeting between nursing schools and hospitals'; 'do not change the clinical settings frequently'; 'evaluate students after being familiar with them'; and 'evaluate them immediately after clinical practice was ended'. In the problems of contents and items of the evaluation tool, the contents of the tool were very abstract and general. The strategies for treating these problems were to evaluate student using the concrete evaluation items'; refrain from evaluation of nursing knowledge', develop the evaluation tools that are fit for a specific clinical setting'; develop the evaluation tools in line with students' knowledge level; and 'carry out evaluation using the proper contents of tool. The problems of criteria of the evaluation tools were the results of the lack of the clear criteria. The strategies for treating these problems were 'develop the criteria of the evaluation tool'; simplify the range of the cores or evaluate students using check-list'; to evaluate students in objective manner'. The problem of evaluators in clinical settings was due to the failure by evaluators who were not prepared for the task. The strategies were 'to educate and prepare the evaluators before evaluation'.

In this study, a questionnaire was compiled by conducting interviews and preliminary surveys, and then handed out to a total of 270 welders working in shipyards to investigate their opinions on welding clothes. By which investigation, it was intended to understand their dissatisfactions and issues with conventional welding clothes and then propose of such welding clothes as may offer better fit and suitability. A total of twenty welding suits were collected to find the locations and degrees of wear and tear. Due to too large differences in the locations and degrees of wear and tear among the clothes, the evaluation was focused on ten suits out of the twenty suits collected. The researcher’s subjective judgment was used to select the nineteen most severely damaged parts, which were then photographed in a uniform distance and evaluated by a group of experts in terms of the degree of damage in order to locate most severely damaged parts and select adequate materials for those parts in designing an experimental suit. Based on two above evaluations, the experimental welding suit was produced in consideration of the design, materials and patterns. A lab evaluation and a site evaluation were conducted to compare the experimental suit and other conventional suits, a lab evaluation and a field evaluation were performed.
