This study was conducted to assess factors associated with the degree of performance of qualify improvement(QI) activities. A mailed questionnaire survey was conducted between September 15 and October 30, 2000, with the staffs being charge of QI at each of the hospitals with 400 beds or greater. Of the 108 hospitals eligible for inclusion in our study, 79 participated, yielding a response rate of 73.1%. After excluding 12 hospitals that did not perform any QI activities, 117 responses from 67 hospitals were used for the analysis. Using the Malcolm Baldrige National Quality Award Criteria(MBNQAC), perceived performance of QI was measured in terms of the improvement of the quality of clinical practice, clinical supporting department, administrative procedure of receiving care, customer satisfaction, efficiency and standardization of work process. Factors evaluated for the association were the extent of QI implementation, compliance to 5 QI principles, participation of hospital CEOs, budget allocation, history of QI, and bed size. Path analysis was performed to assess the relationship between QI performance and these factors. Major findings of this study are as follows. Hospitals showing higher degree of QI implementation (path coefficient=0.5967, p<0.001)) and better compliance with the basic principes of QI(0.5736, p<0.05) tended to achieve better performance. Path analysis results showed that interest and participation of hospital CEOs(0.1954, p<0.05) and compliance with the basic principes of QI(0.4028, p<0.0001) indirectly affected the outcomes of QI by influencing the intermediate variable of the level of QI implementation. This study results suggest that having employees have a good orientation of the basic concept and principes of QI through relevant training be the most important requirement to achieve better outcomes from QI activities. In addition, to educate leaders of hospitals the need of active implementation of QI is important to encourage their participation and draw strong support for QI programs.

Deterministic techniques have been applied in power system planning for many years and there is a growing interest in combining these techniques with probabilistic considerations to assess the increased system stress due to the restructured electricity environment. The overall reliability framework proposed in this paper incorporates the deterministic N-1 criterion in a probabilistic framework, and results in the joint inclusion of both adequacy and security considerations in system planning. The combined framework is achieved using system well-being analysis and traditional adequacy assessment. System well-being analysis is used to quantify the degree of N-1 security and N-1 insecurity in terms of probabilities and frequencies. Traditional adequacy assessment is Incorporated to quantify the magnitude of the severity and consequences associated with system failure. The concepts are illustrated by application to two test systems. The results based on the overall reliability analysis framework indicate that adequacy indices are adversely affected by a generation deficient environment and security indices are adversely affected by a transmission deficient environment. The combined adequacy and security framework presented in this paper can assist system planners to realize the overall benefits associated with system modifications based on the degree of adequacy and security, and therefore facilitate the decision making process.

This study is to enforce to ready basic data of effective dental education program and no smoking and no drinking program for high school students who do smoking and drinking, executed investigation by own recording way using smoking and questionnaire consisted of actual conditions and caries prevention awareness and dental health knowledge degree of drinking to some man high school. Analyzes result that total 487 people respond in SPSS WIN 13.0 programs and got following sequence. Result of this study is as following. 1. Mans high school students had more students who do not than a drinking student and main current received most soju. Third-year student appeared by thing which receive a lot of soju than 1 or 2 class student but different other difference was not seen by class. 2. Mans high school students had more students who do not than a smoking student and a student who smoke more than 3 years was the most. I can know was old since third-year student smokes than 1 or 2 class student. 3. It was not difference that keep in mind by drinking, smoking availability although there were many students who recognize that all of the on-time dental medical examination, sugar intake limitation, fluorine inclusion toothpaste, teeth fluorine application are seldom effective on caries prevention. 4. Recognized that right brushing is effective relatively on caries prevention. I was shown difference that recognized that righter brushing is effective on bad tooth courtesy call than a student who a student who do not smoke does, and keeps in mind according to smoking availability ($x^2$=6.78, p<0.05). 5. I knew best about question of 'A caries may not treat if is painless' among that question ask knowledge for a caries, and appeared by thing which do not know best about question of 'Know that method that supply fluorine in water'. 6. A student who do not drink general dental know-how for a caries was high knowledge degree for a caries than a drunk student but it was no difference that keep in mind by drinking availability. Also, a student who do not smoke by smoking availability was high knowledge degree for a caries than a done student but difference that keep in mind statistically was not seen. 7. It was no difference that keep in mind by drinking availability, but a student who do not smoke by smoking availability was high relation knowledge degree with food and a caries than a smoked student, and I was shown difference that keep in mind according to smoking availability(t=-2.03, p<0.05). 8. Awareness and synthetic estimation degree of knowledge degree a student who do not smoke than a smoked student mouth knowledge degree high, and I was shown difference that keep in mind according to smoking availability(t=-2.03, p<0.05). When see as result such as singularity, family, school, all social institutions may have to help by national business coming and try so that can become national business based on special know-how for development of effective and epoch-making education program as quickly as possible.

This study investigated the relation between oral counting and numerical abilities of young children. The subjects were 33 four-year-old children and 47 five-year-old children from 2 preschools and 2 kindergartens in Kwangju. The test was individually administered in an empty classroom or a hallway by using counting buttons and number cards. The data were analyzed by t-test, Pearsons correlation and multiple regression analysis. The results indicated that (1) older children did better than younger children in oral counting. (2) but the older children did not do better than the younger children in the numerical abilities, (3) the numerical abilities of young children differed according to the degree of oral counting, and (4) the oral counting of young children was one significant predictor of numerical abilities. Findings support the inclusion of activities for oral counting in kindergartens.

The possible interactions between cyclodextrins and biodegradable polyesters were investigated. The hydrophobicity of cyclodextrin could be varied with the methyl substitution of host CD, and the possibility of IC formation and the types of interaction between respective CDs and polyesters were subsequently changed. Further, the effect of cyclodextrins on the morphological change of biodegradable polymer was shown to depend on the degree of IC formation between cyclodextrin and biodegradable polymer as well as on the type of interaction between respective CDs and polyesters. That is, the enhancement and/or the restriction of the crystallization of P(3HB) were observed by the incorporation of various kind of cyclodextrins with different cavity size and hydrophobicity.

[ $YBa_2Cu_3O_{7-\delta}$ ] thin films were deposited by laser ablation using modified melt-textured grown targets. As the laser energy density was increased, the films showed an increasing c-axis orientation and an improvement of superconducting properties. However, at 4 $J/cm^2$, the degree of c-axis alignment and $J_c$ of the film were considerably reduced. These were attributed to the enhanced a-axis outgrowths. It was shown that the increased laser energy density resulted in the formation of $Y_2O_3$ inclusions during the c-axis film growth, and that these inclusions nucleated the a-axis outgrowths.

In this study of the formation of concepts of inclusion by non-disabled preschoolers in inclusive classroom settings, the researcher conducted participant observation and in-depth interviews from March 2004 through June 2005 in a single day care center offering inclusive education in Kyung-gi Province. The non-disabled children exhibited changes in their conception of disability through interactions with disabled children. The non-disabled children could be grouped into three categories: those who were wary of or disregarded disabled peers; those who disregarded disabled peers while helping them out; and those who actively cared for their disabled peers. Not all children went through the same developmental stages. The speed and degree of change in conception varied depending on the individual.

This paper describes the computed tomographic features of ovarian masses in dogs. The CT images of female dogs with a confirmed histological diagnosis of ovarian tumors or ovarian cystic diseases were studied retrospectively. Seven dogs met the inclusion criteria. The morphological features of ovarian tumors and ovarian cystic diseases coincided to a certain degree, but ovarian tumors tended to be predominantly solid. Objective measurements of Hounsfield units (HU) suggest that benign lesions may show lower HU values than malignant tumors and mild contrast enhancement because of the small soft tissue composition. CT is useful for a differential diagnosis of ovarian masses by providing additional information on the imaging features of the masses and an evaluation of metastases.
