본 연구는 대학수학능력시험 직업탐구영역의 "정보기술기초" 교과의 문항 특성 및 문항 양호도 분석을 통해 양질의 문항을 개발하기 위한 분석 자료로 제시하고자 한다. 질적 연구로 내용 타당도 분석을 하였고, 양적 연구로 문항의 난이도, 변별력, 신뢰도 및 오답지 분석을 하였다. 2005년, 2006년 "정보기술기초" 교과 문항 분석결과, 교과 내용이 골고루 출제되었으나 행동영역에 대한 기준이 제고될 필요가 있었다. 또한 "정보기술기초" 교과 문항이 대학수학능력시험에 적합하도록 양질의 문항 개발이 필요하였다. 그러기 위해서는 적절한 난이도와 변별력 있는 문항 개발에 대한 연구가 필요함을 알 수 있다.

이 연구는 한국형 아유르베다 체질을 측정할 수 있는 도구를 개발하기 위한 기초 작업으로 검사지의 신뢰도와 타당성을 검증하는 것이다. 각 대상자는 63문항에 대하여 자기-기입식 설문지를 작성하였다. 아유르베다 체질을 7체질로 개념화하고 우선 271명을 대상으로 실시한 체질 검사의 신체 특성인 41문항에 대한 내적 일관성 신뢰도(Cronbach's ${\alpha}$)는 0.757로, 심리에 대한 질문 22문항에 대한 내적 일관성 신뢰도는 0.616으로, 그리고 전체 63문항의 내적 일관성 신뢰도는 0.840으로 유의미한 수준이었다. 신체에 대한 질문 4번과 심리 9번 문항의 경우 문항 총점과의 상관(item-total correlation)이 음의 값으로 응답의 일관성(신뢰도)이 떨어지는 것으로 나타났다. 그리고 순수 바따, 삣따, 까파 유형 대상으로 신체 4번, 심리 9번을 삭제 한 나머지 61문항의 신뢰도는 0.864로 나타났다. 위의 결과는 복합체질을 제외한 순수체질만을 대상으로 했기 때문에, 응답의 일관성을 나타내는 내적 일관성 신뢰도가 더 높게 나타났다. 그리고 타당도에서는 아유르베다 전문가의 판단과 검사지 응답의 문항점수 간의 일치도 카파(kappa) 계수는 0.619로 유의미한 수준이다. 따라서 본 연구는 한국형 아유르베다 체질 검사지의 개발을 위한 기초자료가 될 것이다.

Service and technology for the future hyper-connected society, which is every information receive through the mobile internet, will be an Internet of Things. Thus, it is mandatory to derive key standardization work item and establish strategy for the global business with the standardization of device and service platform by the application service. In this study, by analyzing the domestic and international market trends, state of technical development, and standardization of technology, we identified the open platform is the stepping stone for achieving the goal which is establishing the virtuous circulation of IoT ecosystem. Also, we defined emphasized key standardization work item for achieving the open platform are network, server, access authentication, billing system, and software platform. After that, we proposed future strategy direction of standardization. This research could be contribute to the IoT service diffusion by realizing IP communication among low power wireless terminals and implementing light-weight standard internet protocol.

The purpose of this study was to develop a self-report scale measuring dysfunctional communication behaviors that Korean husbands and wives may use during marital fights. Based on the four concepts of criticism, contempt, defensiveness, and stonewalling proposed by Gottman(1994a), an initial pool of 38 items was developed. Through expert reviews of the 38 items to assess content validity, preliminary 30 items were selected. Using a sample of 89 married couples who were living in Susan, Korea, we conducted item analyses and exploratory factor analyses with the 30 items. These analyses yielded a final 19-item, four-factor scale : criticism(5 items), contempt(5 items), defensiveness(5 items), and stonewalling(4 items). The internal consistency estimates for these subscales were satisfactory. Finally, using another sample of 228 wives, we conducted confirmatory factor analysis to confirm cross validity of the 19-item, four-factor model. The result indicated that this model fitted the data reasonably well. All standardized factor loadings were significant in this model. The results of this study supported reliability and validity of this scale.

Purpose: The purpose of this study was to develop a job stress scale for hospital-based home care nurses in Korea. The process was construction of the conceptual framework, development of the preliminary items, verification of the content validity, item analysis and test of the reliability. The preliminary items were based on literature review and in-depth interviews with home care nurses. As a result, eight categories and sixty items were selected. These were reviewed by seven specialists for content validity and finally fifty one items were chosen. Data was collected from 180 home care nurses who were engaged in 87 hospitals from August to September 2003. The result of item analysis one was excepted, The final item count was 50. Categories were as follows: overload work(8 items), lack of specialized knowledge and technique(5 items), ethical dilemma(4 items), role conflict(5 items), interpersonal relationships(6 items), visiting home environment(9 items), driving conditions(4 items) and lack of administrative support(9 items), The reliability of the scale by Cronbach's alpha was .948 and the domain's reliability ranged from .649 to .841. The result of this study could be used to measure the job stress of home care nurses. However, for further validity and reliability, repeated studies will be necessary.

For deciding the profitability and feasibility of the construction project, the schematic estimation has to not only link the design decision-making but also estimate the cost with reliability. The Object-based schematic estimation system was developed for easily linking with design-making and supports to evaluate the design alternatives in the design development stage but didn't consider the cost estimated by object supplementary and parameter work item. This research presents the Integrated Object-Parameter Schematic Estimation Model in the design development stage that can lead to more accurately estimate the cost through analyzing historical data from the high-storied office buildings. For the development of the proposed model for schematic estimation, after analyzing and classifying the work items from the Bills of Quantities(BOQs) and drawings of historical data, this research proposed the methods of estimating cost in accordance with attributes of each work item using regression analysis. In addition, a case study is performed for the effectiveness as comparing the proposed model with the previous estimating model.

This study was performed to provide the dress form for high school girls' clothing construction which can reflect the characteristics of their body. Two hundred and forty seven high school girls aged from 15 In 17 were directly measured. The results obtained from this study were as follows ; 1. High school girls' somatotype was similar to that of young adult women. They had the features of well developed upper trunk and well developed breadth, but less developed depth. 2. The correlation between length item and the other items was small enough to interpret that each item was independent. There was a Positive correlation between depth item and girth item. And, Observed correlation between weight and Rohrer's index and breadth, depth and girth item was much larger than expected, which showed that weight and Rohrer's index influenced on fatness factor. 3. Through factor analysis, six factors were extracted from anthropometric measurements. The first factor was representing upper body volumn which expressed the characteristics of somatotype better than any other factors, the second factor was breadth, the third factor was size, the fourth factor was length, the fifth was back shape and the sixth factor was shoulder shape. 4. For development of dress form for high school girls, directly anthoropometric measurements were used. The dress form constructed through this study represented the characteristics of high school girls, therefore this would be very useful to manufacture clothing for them in the future.

The goal of this study is to help for the utilization the national pharmacists test through the analysis of item development management to the foreign pharmacists examination. The United States is going to NABP (National Association of Boards of Pharmacy) initiative under the curriculum in question on the basis of this assessment and develop standards and unified, systematic system to conduct tests pharmacist. Practice oriented (patient scenario, the participation of a pharmacist or perform work, clinical practice) examination is doing in Canada, The UK is asking the for more than 70 percent and the prescription needed for actual calculation in practice prior to testing program, and by the including that allows references use. Our country may introduce the job as a clinical pharmacist, positively. Item management system is integrated into four regions based on the six-year curriculum should be done in harmony proportion of each region. Integration of fusion of each region in accordance with the duties should be come out. It has gradually been able to item management system developed by the United States or Canada. This item notice pharmacist judging the results of the work must be carried out for management upgrading to a form of management with an emphasis on clinical practice in developed countries. Foundation design, development, production and management and test after actively reviewing ways to improve management system for to management systems, a pharmacist to improve the quality of the national examination could be contributing are involved.
