Objectives : This study was carried out to investigate the hepatoprotective effects of mixture with Hovenia dulcis Thunb (HDT) and Acer tegmentosum Maxim(ATM) on D-galactosamine-induced liver failure in rats. Methods : The animals were divided into 4 groups: control, with liver failure and no treatment; H1A1, with liver failure and oral treatment with HDT 1 and ATM 1; H1A2, with liver failure and oral treatment with HDT 1 and ATM 2; H1A4, with liver failure and oral treatment with HDT 1 and ATM 4. The animals were treated for 3 weeks and then examinations of change of body weight, aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma glutamyl transpeptidase ($\gamma$-GTP), total cholesterol, triglyceride, total bilirubin, superoxide dismutase (SOD), catalase, histopathologic change, and complete blood count (CBC) were performed. Results : All experimental groups had significantly decreased AST in serum and markedly increased activity of SOD as compared with the control group. H1A1, and H1A4 significantly decreased ALT in serum and H1A4 at 2 weeks was significantly higher on the change of body weight as compared with the control group. In histopathologic change of liver tissue by light microscopy, all experimental groups showed recovery effects of liver cells which were damaged by D-galactosamine. Conclusions : Based upon these results, it could be assumed that a mixture of HDT and ATM has hepatoprotective and antioxidative effects on D-galactosamine-induced liver failure. Therefore, a mixture of HDT and ATM might be utilized as a protective agent in therapy for liver diseases.

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.

In this study, we designed the finite element models of mandible with varying their connecting types between the prosthesis on implant fixture and 2nd premolar, which were free-standing case(Mf), precision attachment case(Mp), semiprecision attachment case(Ms) and telescopic case(Mt). The basic model of the designed finite element models, which contained a canine and the 1st & 2nd premolar, was implanted in the edentulous site of the 1st & 2nd molar by two implant fixtures. We applied the load in all models by two ways. A vertical load of 200N was applied at each central fossa of 2nd premolar and 1st implant. A tilting load of 20N with inclination of $45^{\circ}$ to lingual side was applied to buccal cusp tips of each 2nd premolar and 1st implant. And then we analyzed three-dimensional finite element models, making a comparative study of principal stress and displacement in four cases respectively. Three-dimensional finite element analysis was performed for the stress distribution and the displacement using commercial software(IDEAS program) for SUN-SPARC workstation. The results were as follows : 1 Under vertical load or tilting load, maximum displacement appeared at the 2nd premolar. Semiprecision case showed the largest maximum displacement, and maximum displacement reduced in the order of precision attachment, free-standing and telescopic case. 2. Under vertical load. the pattern of displacement of the 1st implant appeared mesio-inclined because of the 2nd implant splinted together. But displacement pattern of the 2nd premolar varied according to their connection type with prosthesis. The 2nd premolar showed a little mesio-inclined vertical displacement in case of free-standing and disto-inclined vertical displacement due to attachment in case of precision and semiprecision attachment. In telescopic case, the largest mesio-inclined vertical displacement has been shown, so, the 1st premolar leaned mesial side. 3. Under tilting load, The pattern of displacement was similar in all four cases which appeared displaced to lingual side. But, the maximum displacement of 2nd premolar appeared larger than that of the first implant. Therefore, there was large discrepancy in displacement between natural tooth and implant during tilting load. 4. Under vertical load, the maximum compressive stress appeared at the 1st implant's neck. Semiprecision attachment case showed the largest maximum compressive stress, and the maximum compressive stress reduced in the order of precision attachment, telescopic and free-standing case. 5 Under vertical load, the maximum tensile stress appeared at the 2nd implant's distal neck. Semiprecision attachment case showed the largest maximum tensile stress, and the maximum tensile stress reduced in the order of precision attachment, telescopic and free-standing case. 6. Under vertical load or tilting load, principal stress appeared little between natural tooth & implant in free-standing case, but large principal stress was distributed at upper crown and distal contact site of the 2nd premolar in telescopic case. Principal stress appeared large at keyway & around keyway of distal contact site of the 2nd premolar in precision and semiprecision attachment case, appearing more broad and homogeneous in precision attachment case than in semiprecision attachment case.

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.

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.

개발자 관점의 계층적 소프트웨어 품질 모형(H-SQM)

이선아(Seon-ah Lee),최병주(Byoungju Choi) 한국정보과학회 1999 정보과학회논문지(B) Vol.26 No.12

소프트웨어 품질을 정의하기 위한 여러 가지 소프트웨어 품질 모형(SQM : Software Quality Model)이 개발되어 왔다. 이 모형들은 두 가지 목적을 가진다. 한 가지는 소프트웨어 품질 측적이고, 또 다른 목적은 개발 프로세스에서의 소프트웨어 품질 제어이다. 국제 표준인 ISO/IEC 9126은 소프트웨어 측정을 위한 소프트웨어 품질 모형을 제시하였다. ISO/IEC 9126의 품질 모형은 사용 관점에서 소프트웨어 품질을 정의한 모형이다. 이 모형은 개발 프로세스에서의 품질 제어를 하는 측면에서는 불완전한 모형이다. 소프트웨어의 품질이 프로세스 내에서 어떻게 만들어지는지 볼 수 없는 모형이기 때문이다. 따라서, 개발 관점에서의 소프트웨어 품질 모형이 필요하다. 본 논문에서는 사용 관점인 ISO/IEC 9126 품질 모형을 기반으로 하여 개발 관점에서 소프트웨어 품질 모형을 제안한다. 이 모형은 ISO/IEC 9126과 같이 하위 품질 요소가 중복되지 않는 계층적 품질 모형이면서, 개발 프로세스 내에서 제어 가능한 제품 특성에 기반을 둔 개발 관점의 소프트웨어 품질 모형이다. 본 논문에서는 소프트웨어 품질 모형 구축 시, 품질속성간의 선후조건관계를 설정하여 품질 속성가 중복되었던 제품 특성을 한 품질 속성 내 귀속시킨다. 품질 속성 별 제품 특성을 기반으로, 프로세스 내에서 제품 특성을 측정하는 메트릭스를 제안한다. 본 논문에서는 제안한 품질 모형과 ISO/IEC 9126을 비롯한 기존 품질 모형과 비교 분석한다. Several SQMs(Software Quality Models) have been developed to define a software quality. These models have two goals. One is to measure a software quality, the other is to control a software quality. The SQM of ISO/IEC 9126 is defined from the user's viewpoint. This model is an incomplete model in controlling a software quality in the development process. Since this model cannot show how to build a high quality software, the SQM of the developer's view is needed. We suggest the SQM of the developer's view. This model is a completely hierarchical model and is based on product properties. For this model, we define implicative relations among quality attributes for 1:m relations of quality attributes and product properties. So, we solve the problem of a quality attribute overlapping with other quality attributes. We suggest metrics based on our SQMs. Further, we evaluate our SQM by comparing our SQM with other SQMs.

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.
