Based on the thinking that people can understand more clearly when the problem is related with their prior knowledge, the Purpose of this study was to analysis students' informal knowledge, which is constructed through their mathematical experience in the context of real-world situations. According to this purpose, the following research questions were. 1) What is the characteristics of students' informal knowledge about fraction before formal fraction instruction in school? 2) What is the difference of informal knowledge of fraction according to reasoning ability and grade. To investigate these questions, 18 children of first, second and third grade(6 children per each grade) in C elementary school were selected. Among the various concept of fraction, part-whole fraction, quotient fraction, ratio fraction and measure fraction were selected for the interview. I recorded the interview on digital camera, drew up a protocol about interview contents, and analyzed and discussed them after numbering and comment. The conclusions are as follows: First, students already constructed informal knowledge before they learned formal knowledge about fraction. Among students' informal knowledge they knew correct concepts based on formal knowledge, but they also have ideas that would lead to misconceptions. Second, the informal knowledge constructed by children were different according to grade. This is because the informal knowledge is influenced by various experience on learning and everyday life. And the students having higher reasoning ability represented higher levels of knowledge. Third, because children are using informal knowledge from everyday life to learn formal knowledge, we should use these informal knowledge to instruct more efficiently.

When a system is developed, requirements document is generated by requirement analysts and then translated to formal specifications by specifiers. If a formal specification can be generated automatically from a natural language requirements document, system development cost and system fault from experts' misunderstanding will be decreased. A pronoun can be classified in personal and demonstrative pronoun. In the characteristics of requirements document, the personal pronouns are almost not occurred, so we focused on the decision of antecedent for a demonstrative pronoun. For the higher accuracy in analysis of requirements document automatically, finding antecedent of demonstrative pronoun is very important for elicitation of formal requirements automatically from natural language requirements document via natural language processing. The final goal of this research is to automatically generate formal specifications from natural language requirements document. For this, this paper, based on previous research [3], proposes an anaphora resolution system to decide antecedent of pronoun using natural language processing from natural language requirements document in Korean. This paper proposes heuristic rules for the system implementation. By experiments, we got 92.45%, 69.98% as recall and precision respectively with ten requirements documents.

This paper aims to analyse the recent changes in social welfare services from a relational perspective. Discourses of the privatization of welfare state, the welfare mix approach, and consumerism have provided frames for interpreting the changes in social services in Korea. The nature of social welfare services, being a "relational goods" requires its focus to be in its relational aspects: the relation between service user and service practitioner; the relation between service user and provider; the relation between service user and government; the relation between service practitioner and provider; the relation between service practitioner and government; and the relation between service provider and government. Analysis of such relations will explore their transformation toward formalness and equality in social welfare services. In conclude, the study reveals a process of modernization, defined as a transition from informal relations to formal contractual relations, based on one's rights, responsibilities and obligations. Previous relations, of paternalistic, arbitrary and hierarchical characteristics, can be seen as being substituted by more formal, institutionalized and equalized relations. In terms of service purchasing contract between service user and service provider and employment contract between service provider and service worker are recognized with the latter characteristics. This relational analysis leads a discussion concerning the creation of institutional basis of one's rights and responsibilities in the fields of social welfare services in Korea.

The purpose of this study was to provide basic materials needed to enhance quality of organizational life by identifying the improvements of labor union management in the perspective of general hospital organization management. The subjects of this study were 428 employees in 8 Hospitals in Metro Capital including Seoul. Materials were collected from administrators, nurses and medical technicians in target hospitals from November 10 to November 30, 2006 through survey questionnaires. The main results of this study were as follows: 1. The commitment level of the subjects according to their characteristics was higher in older employees than the younger ones, large family to support than small family to support and those who had higher positions in labor union. 2. The commitment level of the subjects according to the Job and role related variables were higher those who had higher satisfaction level to their job, role conflict in all hospitals. 3. The commitment level of the subjects according to union related variables, variables jointly controlled by union and employer was statistically significant positive correlation. 4. The results of multiple regression analysis shows that formal and informal socialization, satisfaction with the labor union's were all found as important antecedents of labor union commitment. 5. The results of AMOS shows that structure characteristics of hospital, Job and manager satisfaction, socialization were statistically significant labor union satisfaction. The satisfaction level of labor union was statistically significant labor union commitment To summarize study results, the level of commitment in labor union depends on job satisfaction, managers' attitudes, union satisfaction factors, their colleagues attitudes toward union. Therefore hospital managers should have democratic and flexible attitudes toward labor union. Additionally, as formal and informal socialization is important determinant in union commitment, hospital managers should have countermeasures to enhance the colleague attitude and job satisfaction level of hospital employees. Moreover, as managerial factors of the principal of hospital influence union commitment directly, the attitudes of hospital managers toward union and transparency of hospital management should be improved.

Network management system(NMS) provides not only effective monitoring and controlling of network which consists of heterogeneous network elements but prompt response to users' need for high-level communication services. Recommendations of ITU-T and ISO stipulate the managerial abstraction of static and dynamic characteristics of network elements, management functions as well as management communication protocol. But the current description method does not provide the formal mechanism for the behavior characteristics of managed objects in clear manner but in natural language form, the complete specification of managed objects is not fully described. In this paper, we describe determinants for the behaviour of managed objects applicable to every managed object, and present a language for specifying behavioral aspects of managed objects based on their temporal and active properties.

The purpose of this study was to conduct an exploratory and descriptive survey study design to examine 1) the physical difficulty by care task, 2) overall occupation-related physical burden by the characteristics of caregivers and care receivers, and 3) the level of help by the use of care robots and devices among formal caregivers working in facilities for older adults. In this study, 308 formal caregivers working in facilities were recruited from 8 nursing homes and 5 geriatric hospitals between Aug. 2021 and Sept. 2022 in South Korea. There were significant differences in ADLs between nursing homes and geriatric hospitals: eating, dressing, hygiene, transfer to bed, transfer to the toilet and walking. For each care item, the items the caregivers had the most difficulty ranked first were bathing, excretion assistance, and mobility support. The difference in occupation-related physical burden according to general characteristics was found to have statistically significant differences in female and bad perceived health. Among the 205 caregivers who had experience using care robots and devices, pressure ulcer prevention was the most experienced one, and those also were the most helpful and exercise aids were the least helpful. In order to reduce the physical burden on care providers, it is necessary to develop and introduce a care robots centered on the care site. Furthermore, national level public support systems are required to enable facilities to actively utilize care robots and devices.

Recently, the sonnet and the shijo, each representing French and Korean formal poetries, are tend to be read with the eyes only, as were more accustomed to written literature. But even after almost three millennia of written literature and increased use of digitalized poems, poetry retains its appeal to the ear as well as to the eye. To read a poem only by eyes might be wrong because it is designed to be read aloud by mouth and understood by ear, and will decrease the aesthetic sense otherwise. It is essential to find the right way to recite a poem in this dramatically changed society, and is especially important when many shijos are changing into digitalized forms to adapt the new wave of our society. The sonnet and the shijo emphasize the importance of the harmony of sounds and rhythms with certain structure, and have their own prosodies. The emotions of the speaker in poems are expressed with words. When they are pronounced. each phoneme has its own phonemic characteristics. When comparing the The Broken Bell(Baudelaire) and Chopoong ga (Jong Seo Kim) in terms of prosody and phonetics. the speakers emotions are closely related with the phonetic structure of each word. In The Broken Bell, the phonetic value of rhymes, repeated phonemes, concentration of front and back vowels. rhythms of onesyllable words shape the overall image of this poem describing the productivity of bells as appose to the sterility of the soul. Chopoong ga also shows the determined and strong will of the speaker by frequent glottalized sounds. distribution and concentration of certain vowels. and frequent use of plosives. As you see in these examples, phones, beats, and rhythms are not the mere transmitter of meaning but possess their expressive values of their own and should be the first to be considered when reciting a poem.
