Fur garment has long been the conventional symbol for luxury, or conspicuous consumption. However, as fashion items began to diversify as part of overall fashion trend, fur items are now more about individual taste and style than just lavishness. Synthetic fur is especially emerging as a new promising fashion material, with a touch almost like natural fur at an affordable price. Along with the emergence of 'Vegan Fashion' trend, synthetic fur is establishing itself as a popular fashion textile. This study is an attempt to investigate subjective evaluation and physical properties of natural and synthetic furs, whose results will further serve as basic data in developing synthetic fur materials. Sensory and emotional evaluations are carried out on natural and artificial furs. For analysis, factors such as weight, thickness, air permeability, gloss and compressibility were surveyed to observe how they influence the physical properties. According to the subjective evaluation, natural and artificial fur samples do not differ in conspicuous ways in appearance. Experiments on physical properties, specifically warm/cool touch experiment, show that natural fur has a slightly higher warm sensation than artificial fur. Luster analysis by using a microscope revealed that there are subtle qualitative differences between natural and artificial fur. During the subjective evaluation, subjects found it hard to state distinct quantitative differences in luster. A survey as a means of assessing qualitative differences in gloss seems to be necessary to complement the evaluation. Results from this study will potentially serve as resources for diversification of fashion product designs using synthetic fur.

The purpose of this study was to investigate the reason of interruption and the knowledge of breastfeeding. The samples of 117 mothers who have the babies between age from 1 month to 12 months were selected from one university hospital and one public health care center in J City. The data were collected with the questionnaire during the period from the January. 5. 2002 through January. 30. 2002. Analysis was done by using frequency. percentage. t-test. ANOVA. The results of this study can be summarized as follows. 1. The comparison of the method of feeding by general characteristics. income state(p= .019), rearing supporters(p=.026) and infant age(p=.03) have shown significant difference as the variables affecting breastfeeding practice rate. Breastfeeding rate were 24.8%. mixed- feeding type, 14.5%. milkfeeding type. 60.7%. 2. The major reason which breastfeeding be done was 'for health of baby'. In the period of breastfeeding, a large number of mothers answered' up to. 6 months'. The major reason of breasttfeeding interruption was 'insufficient quantity of breastmilk'. 3. The mean of knowledge on breastfeeding by feeding patterns were the highest in the breastfeeding group(F= 10.228, p= .000). 4. In a grade of each item on knowledge of breastfeeding, over 80% of mothers wrongly answered in two items; components comparison between breastmilk and cow's milk and when the mother fell sick. whether she have to be feed breastmilk. or not. In the conclusion. this study revealed that knowledge of breastfeeding promoted practice of breastfeeding. However we suggest that systemic and supportive breastfeeding program for promoting the knowledge and the practice rate of breastfeeding have to be provided by nurses.

소프트웨어 개발 과정에서 제품의 품질 척도를 적용하는 방법

이선아(Seon-ah Lee),최병주(Byoungju Cho) 한국정보과학회 2000 정보과학회논문지 : 소프트웨어 및 응용 Vol.27 No.3

고품질의 소프트웨어를 개발하기 위하여, 소프트웨어의 품질을 측정하는 메트릭스가 활발히 개발되었고 근래에는 객체지향 메트릭스도 제시되고 있다. 그러나 개발 과정에서 품질을 관리하기 위하여 메트릭스를 이용하는 방법에 대한 연구는 제대로 이루어지고 있지 않다. 이는 개발 과정에서 적용되는 메트릭스의 의미를 전체적인 품질 관점에서 이해하기가 어렵기 때문이다. 본 논문에서는 제품 특성을 기반으로 정의된 소프트웨어 품질 모형(H-SQM)을 이용하여 개발 과정에 소프트웨어 품질 메트릭스를 적용하는 방법을 제안한다. 이 방법에서는 H-SQM을 표현한 원인-결과 다이어그램을 공정분석도로 바꾼다. 공정분석도에 따라 개발 단계별로 소프트웨어 품질 메트릭스를 적용한다. 이러한 방법으로 개발 과정에서 소프트웨어의 품질을 효율적으로 개선해 나갈 수 있도록 메트릭스를 적용 할 수 있게 된다. In order to develop high quality software, software metrics have been made to assess the quality of software, and recently, many object-oriented metrics have been suggested for this purpose as well. However, research on the utilization of metrics to control software quality in a development process has been inadequate. This is due to the difficulty in assessing the significance of metrics in a software development process from the perspective of overall software quality. In this paper, we propose a method of applying metrics to a development process using the Hierarchical Software Quality Model(H-SQM) which is defined in terms of the products' special features. The method represents the H-SQM as the cause-and-effect diagram and changes the diagram to the process-analysis diagram. And it applies software quality metrics to each development stage by the process-analysis diagram. In this way, we could utilize the software quality metrics efficiently in order to improve the quality of software in the software development process.

현금흐름의 개별적 정보가치를 평가하기 위하여 영업활동, 재무활동, 투자활동의 현금흐름이 주가수익률에 미치는 영향을 다변량회귀분석을 통하여 실증분석하였다. 각각의 현금흐름 정보는 현금흐름표상의 실제자료를 이용하였으며, 표본은 2000년부터 2008년까지의 기업을 대상으로 하였다. 분석결과, 영업활동으로 인한 현금흐름은 주가수익률에 양(+)의 관련성을 미치는 것으로 나타났다. 통계적으로 유의하지 아니한 결과가 선행연구들과 차이를 보이는데 이는 기간과 표본의 차이로 보여진다. 투자활동으로 인한 현금흐름은 통계적으로도 유의성을 가지고 있으며 주가수익률에 음(-)의 관계를 가지는 것으로 나타났다. 기업을 계속적으로 유지, 성장, 발전시키기 위한 활동이 투자활동인데 이러한 기업의 투자활동으로 인한 효과는 일정기간 이후에 실현이 되는 것이라서 유형자산 취득 등의 현금의 유출과 대여금등의 현금유입 등의 정보가 현재의 투자자들에게 영향을 미치고 시장에 반영되어 지는 것으로 보여진다. 재무활동으로 인한 현금흐름도 통계적으로 유의하였으며 주가수익률에 양(+)의 관련성을 미치는 것으로 나타났다. 신주발행이나 배당금지급등의 재무활동으로 인한 현금흐름이 주식가격에 영향을 주고 있음을 보여주고 있는 것으로 재무활동으로 인한 현금흐름도 회계정보로서 유용성을 보여준다. Accounting income reported by accural-basis serves as the numbers representing management performances, being used in decision making of accounting information users most significantly, while cash flow serves as thee numbers of such performances and is calculated according to cash-basis. These two items are difference each other in properties and substances and may have differences with each other in enterprise value. Because accounting income has considerably vulnerable to satisfy all the desires of information users, cash flow, calculated by cash base, has attracted more attention in financial reports of firms. With the results of researches showing information by cash flow has unique information that are not presented by accrual-basis, cash-basis and accrual-basis are being studies. The purpose of this study is to examine the basic discussion on the usefulness of accounting income and cash flow and to demonstrate whether information of cash flow has information on CAR by regression analysis based on financial materials of firms reported between the year of 2000 and 2008. According to the results of this study, UCFO had positive effects on CAR, However, the results of the regression analysis were statistically insignificant maybe because the period was long and the amount of samples was much. UCFI had negative number effects and UCFF had positive number effects on CAR, and the results of the analysis were significant. This result shows information of cash flow is useful is useful as accounting information value.

이 연구는 아제라늄을 함유한 기능성 팬츠의 착용이 성인 남성의 혈행 동태 및 생식 기능에 미치는 영향을 검토하였다. 연구대상은 성인 남성을 아제라늄을 함유한 기능성 팬츠 착용 집단(Ageranium pants group; APG, n=10)과 일반 팬츠 착용 집단(Normal pants group; NPG, n=10)으로 각각 분류하였다. 모든 대상자는 1개월간의 간격을 두고 무선 할당 교차설계 방식으로 혈행 동태{귓속체온(최대 온도), 적외선체열(고환, 엉치뼈), 지점 가속도 맥파(자율신경 활성도, 자율신경 균형도, 스트레스 저항도, 스트레스 지수, 피로도, 미분 맥파 지수, 혈관 탄성도 및 잔혈량)} 및 생식 기능(배뇨 기능 7문항, 배변 기능 9문항, 성 기능 9문항)을 팬츠 착용 전과 착용 1, 2, 3 및 4주 후에 각각 측정하였다. 주요한 결과는 다음과 같다. 고환의 적외선 체열은 집단(F=3.274, p=.004), 집단 및 시기(F=3.052, p=.022) 간에 통계학적으로 유의한 상호작용 효과가 나타났으며, 자율신경 활성도는 집단(F=4.429, p=.049), 집단 및 시기(F=4.418, p=.048) 간에 유의한 상호작용 효과가 나타났다. 또한, 미분 맥파 지수는 집단(F=13.857, p=.031), 집단 및 시기(F=7.286, p=.042) 간에 통계학적으로 유의한 상호작용 효과가 나타났다. 한편, 생식 기능은 집단 및 시기 간에 통계학적으로 유의한 상호작용 효과가 나타나지 않았다. 이상의 결과, 이 연구에서 아제라늄을 함유한 기능성 팬츠의 착용은 성인 남성의 혈행 동태에 효과가 있다는 사실을 확인하였다. The purpose of this study was to determine the effects of wearing functional pants with ageranium on hemodynamic and fertility in adult men. A total of 10 man were randomly crossover design assigned to ageranium pants group (APG; n=10) and normal pants group (NPG, n=10). Hemodynamic {(eardrum temperature (maximum temperature), thermography (testis and sacrum), acceleration derivative photoplethysmogram (autonomic nerve activity, autonomic nerve balance, stress resistibility, stress index, fatigue index, differential pulse index, blood vessel tension and remained blood volume)} and fertility (7 items for urination index, 9 items for defecation index and 9 items for defecation index) were measured before, 1 (1W), 2 (2W), 3 (3W) and 4-week (4W) after wearing pants. In results, thermography of testis were statistical significant interactions effect between the group (F=3.274, p=.004), and group ☓ time (F=3.052, p=.022). The autonomic nerve activity were statistical significant interactions effect between the group (F=4.429, p=.049), and group ☓ time (F=4.418, p=.048). The differential pulse wave index were statistical significant interactions effect between the group (F=13.857, p=.031), and group ☓ time (F=7.286, p=.042). However, fertility in APG and NPG were not statistically significant interaction between groups and time. These results suggest that wearing functional pants with ageranium improves hemodynamic in adult men.

The purpose of this study is to investigate the effect on maternal perception of her infant and the infant`s behavior development through maternal education designed to provide information of the capabilities and the individual characteristics of her infant. The subjects were 48 pairs of normal infants and mothers at three different hospitals, 24 pairs for the intervention group and 24 pairs of the control group. The survey was conducted from July 30 to October 6, 2001. The results of this study were as the following. A maternal perception of her infant was significantly different between the two groups, more positive in the intervention group than in the control group. The information and understanding of behavioral characteristics of the infant are an important factor influencing maternal perception for her infant and general development of the infant. On the basis of these results, the educational intervention method of this study may be worth utilizing in nursing practice. The practitioners of hospitals have to establish a system that it offers an education of understanding the infant`s behavioral characteristics during the hospitalization after delivery.

다중지능 이론에 기초한 강점지능 활용 국어학습이 ADHD 학생의 부적응 행동에 미치는 영향

본 연구는 다중지능 이론에 기초한 강점지능 활용 국어학습이 ADHD 학생의 부적응행동에 미치는 영향을 알아보는 데 그 목적이 있다. 이를 위하여 A광역시 소재의 4학년ADHD학생 1명을 대상으로 그 학생의 부적응행동 중 과제 불이행행동, 수업방해 행동, 욕설하기 행동에 다중지능의 강점 지능이 미치는 영향을 알아보기 위하여 다중지능검사를 실시한 결과 대상 학생은 언어지능이 강점지능으로 나타났다. 모든 교과 중에서 언어지능을 가장 많이 활용할 수 있는 교과가 국어과이므로 대상학생이 자신의 강점지능을 충분히 활용할 수 있도록 언어지능 중 토론과 모둠학습의 형식으로 국어과의 교수-학습 방법을 재구성하였다. 대상 학생의 강점지능인 언어지능이 학습과제불이행 행동, 수업방해 행동, 욕설하기행동에 미치는 영향을 알아보기 위하여 행동간 중다기초선설계를 실시하였다. 그 결과 첫째, 다중지능 이론에 기초한 강점지능 활용 국어학습은 ADHD학생의 학습과제불이행 행동이 감소시키는데 긍정적인 효과를 나타내었다. 둘째, 다중지능 이론에 기초한 강점지능 활용 국어학습은 ADHD학생의 수업방해 행동을 감소시키는 긍정적인 효과를 나타내었다. 그러나 셋째, 다중지능 이론에 기초한 강점지능 활용 국어학습은 ADHD학생의 욕설하기 행동을 중재기간동안에는 긍정적인 효과를 나타내었으나 유지기간에는 다시 기초선 수준만큼의 욕설하기 행동이 나타났다. 이와 같은 연구 결과를 볼 때 가드너의 주장처럼 사람은 각기 다른 강점 지능을 가지고 있고 ADHD학생의 문제 행동을 개선하기 위해서 다중기능 이론에 기초한 강점지능 활용한다면 ADHD 학생의 문제행동의 개선에 긍정적인영향을 줄 것이다. The purpose of the study was to understand how strong intelligence-focused Korean learning, based on Gardner`s Multiple Intelligence Hypothesis, affects learners diagnosed with ADHD. In order to achieve the research goal, the study conducted a multiple intelligence test targeting one individual ADHD learner, and re-designed a Korean learning-teaching plan focusing on the verbal intelligence, a strong intelligence. The target learner in the study certainly had competent verbal intelligence and yet, the learner did not like writing but loved speaking in front of others. In consideration of the fact, the study created a class mostly focusing on group speaking activities and discussions, and looked into how such activities influence the learner`s problem behaviors as assignment nonfulfillment, actions of disturbance and swearing. The results of the study are summarized as follows. First, the strong intelligence-focused Korean learning based on Gardner`s Multiple Intelligence Hypothesis turned out to have a positive influence on reducing of the ADHD learner`s assignment nonfulfillment. During the intervention instead of the baseline session, the assignment nonfulfillment behavior was remarkably decreased. Although the nonfulfillment rate during the maintenance period was a bit higher than the intervention, since the rate appeared lower than the baseline session, the study concluded that the strong intelligence of the multiple intelligences would be effective in reducing problem behaviors of a ADHD learner. In addition, for a learner with the strong verbal intelligence, the study confirmed that it would be better to give the learner an individual class, and a chance to speak in front of the whole class while encouraging the learner to share ideas with other peers in the group. Second, the strong intelligence-focused Korean learning based on Gardner`s Multiple Intelligence Hypothesis was observed to have a positive influence on the ADHD learner`s disturbance actions during class. For the intervention, the target learner in the study was assigned to a proper group responsibility rather than a private assignment with several chances to use one`s strong intelligence, the verbal intelligence. During this intervention, the actions of class disturbance were down to 34.7% comparing to the baseline session. The rate was reduced even during the maintenance period than the baseline session and for that reason, it was learned that the strong intelligence-focused Korean learning would decrease a ADHD learner`s disturbance actions during class. Third, the study figured out that the strong intelligence-focused Korean learning based on Gardner`s Multiple Intelligence Hypothesis would reduce the ADHD learner`s swearing in a positive way. During the intervention, the frequency of the target learner`s swearing decreased a great deal but during the maintenance period after the intervention, the learner swore as much as one did during the baseline session. The study has comp up with proposals as follows. First, the problem resided in how to generalize the results of the study. However, the study had only one target learner whose intelligence was relatively higher than those of other ADHD learners. In other words, from the beginning, the target learner in the study was able to produce more positive results in a group discussion, and if more participants could be examined in a following study on the same topic, results of such study would be more generalized. Second, this study aimed to investigate effects of strong intelligence of the multiple intelligences on problem behaviors of ADHD learners. However, it would be significant at the same time if a following study in the future discusses how to help ADHD learners to make up for their weak intelligences while examining weak intelligences of the ADHD learners, and making a use of their strong intelligences. Third, the strong intelligence of the multiple intelligences could be used to fix problem behaviors of not only ADHD learners but also general students. The general students do have strong intelligences of their own, and problem behaviors that they would want to improve. Hence, the study suggests that teachers generalize Gardner`s Multiple Intelligence Hypothesis, providing the students chances to use their strong intelligences both at school and in daily life. That way, the students will finally build up positive self-consciousness inside them with the help of the teachers.The purpose of the study was to understand how strong intelligence-focused Korean learning, based on Gardner`s Multiple Intelligence Hypothesis, affects learners diagnosed with ADHD.
