Prepurchase decision making process was investigated for the female high school students grouped by fashion leadership. Differences in the fashion leadership were also investigated among the groups determined by demographic characteristics. Data were obtained from 600 female students attending at 4 different high schools in Seoul by self-administered questionnaires, and 430 were used for the data analysis. Respondents were divided into 5 groups by fashion leadership: innovators(6.3%), early adopters(29.8%) , early majority(43.7%) , late majority(16.9%) , laggards(3.3%) , The groups with higher monthly allowances and monthly clothing expenditures showed higher fashion leadership. At the problem recognition stage, students with higher fashion leadership felt buying needs more often than those with lower fashion leadership. At the information search stage, students with higher fashion leadership tended to use higher number of information sources and mass media, visited stores more often, spent more time and collected new information more often, and tended to show higher satisfaction levels with searched information than students with lower fashion leadership. Leaders tended to search information at bonded goods stores and small shops in the area, and laggards prefered to visit small stores in the market. At the alternative evaluation stage, students with higher fashion leadership reported to use higher number of evaluative criteria and consider brand name, acknowledgment of others, becomingness with wardrobe as important criteria for evaluating apparel products; those with lower fashion leadership thought utility, comfort, size, sewing quality an6 fit as key criteria.

If we don't know the intention of altering course of a target ship when being in a head-on or a crossing situation, we may be confused about our decision making to change our course for collision avoidance and be in a danger of collision. In order to solve these problems, we need to develop an automatic detection system on altering course of a target ship for efficient collision avoidance. In this paper, we proposed an early detection system on altering course of a target ship using the steering wheel signal. This system will contribute to the reduction of collision accidents and also be used to the VTS system and the analysis of marine accidents.

As a part of attempts to understand better mathematics classroom culture, this paper first reviews plausible factors which influence the mathematics teacher's own development of instructional goals. The proposed factors consist of teacher characteristics and sociocultural factors. The teacher factors include learning and teaching experience, knowledge, beliefs, and personality traits. The sociocultural factors include cultural and educational norms, curriculum development and administration, teacher education, and professional models with community, This paper then presents detailed interview questions to explore significant influences on the teacher's conceptions of mathematics and its teaching. The interview probes 12 topic areas: (a) early influences on becoming a teacher, (b) the decision to become a teacher, (c) the teacher education years, (d) early mathematics interests, (e) early teaching experiences, (f) career path, (g) influence of peers within the school, (h) influence of administrators, (i) professional development, (j) professional self-development, (k) mathematics teaching, and (i) educational policies.

This study was performed to evaluate the early estimation of compressive strength of concrete using mineral admixture by refrigeration curing method. It was a method of early decision for the property of concrete after the curing age 28days through the refrigeration curing at $-18{\pm}3^{\circ}$ for five hours. The test result was fixed connection between the curing age 28days and 31hours by the compressive strength test through the standard curing and refrigeration curing. Accordingly, it can be reduced the mistake of construction work by forecasting the property of concrete through the refrigeration curing.

Purpose: There is increasing necessity of using cord blood cell worldwide. In order to improve the effectiveness of cord blood's usage in Korea, the study of knowledge and attitude regarding cord blood is needed. Method: As descriptive correlation study, data was collected from 212 early postpartum women who stored or donated cord blood from 2007 April to July. Data was analyzed using $X^2$-test, t-test, ANOVA, and logistic regression. Result: Total score of knowledge and attitude of early postpartum women who donated cord blood was higher than who stored. According to the source of education and the source of influence toward decision of using cord blood, early postpartum women who educated or influenced by mass media showed difference in attitude. Job status and income, and attitude of cord blood were the predictor of cord blood donation. Conclusion: Attitude regard to cord blood affect to usage of cord blood, and the attitude and knowledge of cord blood in early postpartum women who donated it higher than who stored.

The main purpose of this methodological study was to develop an assessment tool and intervention protocol for child and family with childhood cancer at early diagnosis stage. The assessment tool and intervention protocol was developed by extensive literature review and consultation with experts. Review of nine domestic and sixty-six international journal articles were done to identify stress, interventions, coping strategies and adjustment of children with cancer and their family. Results were as follows; First, assessment at the early diagnosis stage need to include information on patient, family, and patient/family attitude toward diagnosis and treatment. Second, intervention protocol for children with cancer includes control physical symptoms, manage the side effects of chemotherapy and diagnostic or therapeutic procedures, control emotional responses, provide support and information, assist decision-making and adjust to environment. Third, intervention protocol for family includes controlling emotional responses, provision of informations, inducing family support to patient, improving family cohesion, supporting siblings and supporting spiritual growth. In conclusion, the early diagnosis stage in cancer treatment is important for child and family since this stage greatly affects the overall adjustment of child and family to live with cancer. Therefore, pediatric nurses need to be sensitive to the need of patient/family and systematically manage their needs at this stage.

국내건설시장의 불확실성과 해외 EPC도급 사업의 수주 경쟁력 약화로 인해, 국내건설기업의 해외개발사업에 대한 관심은 최근 크게 증가하고 있다. 해외개발사업을 수주하기 위해서는 오랜 준비기간과 판매비용이 투입되기 때문에 사업발굴초기에 수주까지 달성할 수 있는 사업을 선별하는 것은 의사결정자에게 매우 중요하다. 하지만, 기존 연구는 사업초기단계보다는 사업개발 전체단계 관점의 타당성평가가 대부분이었다. 따라서 본 연구에서는 31개 해외개발사업을 대상으로 사업발굴단계의 사업추진역량, 상업적 조건, 비상업적조건, 전략 및 공익성의 28개 의사결정요소와 사업수주 성공/실패의 관계를 분석하였다. 이를 통해 다음과 같은 결론을 도출할 수 있었다. 첫째, 입찰형 사업과 제안형 사업의 리스크는 다소 다르며, 제안형 사업이 대체적으로 리스크가 크기 때문에 보다 나은 사업추진역량과 금융조건을 필요로 한다. 둘째, 사업발굴단계 이후에도 개선이 쉽게 되지 않는 사업추진역량의 중요도가 높다고 분석되었다. 셋째, 상업적 조건의 경우, 사업발굴단계에서는 판단하기 어려운 부분이 있으나 수주가능성을 판단하는데는 유의미하게 중요한 요인으로 평가되었다. 넷째, 비상업적 조건과 전략 및 공익성은 사업발굴단계의 수주가능성 예측에는 유의미한 변수로 평가되지는 않았다. 본 연구는 해외개발사업의 수주가능성을 발굴단계 초점을 맞추어 실제 프로젝트를 기반으로 실증적으로 분석했다는데 의의가 있다.

본 연구에서는 데이터 마이닝의 방법인 의사결정나무와 인공신경망을 이용하여 리튬 이차전지의 전류밀도 특성에 대해 핵심 설계 인자를 도출하고 비교하였다. 먼저 의사결정나무-인공신경망 모델을 이용한 설계방법으로, 비선형성을 나타내는 초기 극판 설계인자들 중에 의사결정나무 모델을 통해 주요 설계 인자를 도출한 다음 인공신경망을 이용하여 설계인자들 간의 중요도와 전류밀도와의 가중치 분석을 수행하였다. 두 번째 방법은 인공신경망 모델만을 이용한 방법으로, 초기 설계인자들을 별도의 주요 인자 도출 과정 없이 모두 인공신경망을 구축하는데 사용하여 전류밀도와의 연관성 및 가중치를 분석하였다.
