The purpose of this study was to examine what types of physical, psychological, and social problems elderly and what sort of education they were in want of to tackle their problems. The subjects in this study were 109 elderly who used Lifelong Education Center and social welfare agencies in Suwon. The data were gathered from September 1 through the 30th day, 2004. The instrument was questionnaires prepared by this researcher after reviewing relevant literature. The collected data were analyzed with SPSS(Ver. 11.0) program. The major findings were as follows: 1. Among different types of problems with the elderly people investigated, 42.2%, found economic problems most serious, followed by health problems with 33.9%. 2. They got a 4.36, 4.02 and 4.70 in needs for physical, psychological, and social education respectively. 3. Regarding physical area, the elderly people were most in want of education about the prevention of dementia. As to psychological area, they attached the meaning of death and preparation for that. Social area, they wanted to learn about problems with the elderly. Based on the findings of the study, I suggest that More educational programs geared toward the elderly should be developed in response to their needs for education.

A neural network based adaptive reconfigurable flight controller is presented for a class of discrete-time nonlinear flight systems in the presence of variations of aerodynamic coefficients and control effectiveness decrease caused by control surface damage. The proposed adaptive nonlinear controller is developed making use of the backstepping technique for the angle of attack, sideslip angle, and bank angle command following without two time separation assumption. Feedforward multilayer neural networks are implemented to guarantee reconfigurability for control surface damage as well as robustness to the aerodynamic uncertainties. The main feature of the proposed controller is that the adaptive controller is developed under the assumption that all of the nonlinear functions of the discrete-time flight system are not known accurately, whereas most previous works on flight system applications even in continuous time assume that only the nonlinear functions of fast dynamics are unknown. Neural networks learn through the recursive weight update rules that are derived from the discrete-time version of Lyapunov control theory. The boundness of the error states and neural networks weight estimation errors is also investigated by the discrete-time Lyapunov derivatives analysis. To show the effectiveness of the proposed control law, the approach is i]lustrated by applying to the nonlinear dynamic model of the high performance aircraft.

Objective: The purpose of this study was to learn from Korean female defectors about their views of child-rearing experiences in South Korea. This study explored how 7 North Korean female defectors with young children developed child-rearing microideologies that acknowledge both North Korean cultural ideology and South Korean cultural ideology. Methods: To examine North Korean female defectors' child-rearing experiences, indepth interviews with 7 North Korean female defectors with young children were conducted. Results: Four theme clusters, 11 themes, and 47 meanings were found from a phenomenological analysis with indepth interview data. Based on the themes, three types of child-rearing microideologies were identified: (1) separation,(2) assimilation, and (3) integration. Each type of child-rearing microideology can be understood with a meaningful phrase "there is no choice", "nevertheless" and "because I came here to be better," respectively. Conclusion/Implications: This study provides knowledge on the individual-specified child-rearing strategy of North Korean female defectors with young children and suggests the necessity of diverse policy proposals based on the child-rearing microideology types.

With the rapid changes of business environments and the tremendous amount of information generated from those environments, most companies must learn to manage those changes and information more effectively. Furthermore, within those amounts of information, the information that meets with achieving the goal of each company should be selected and managed as a core competency, i.e. the knowledge, visible and invisible assets of the company. Knowledge management, as a tool of creating, sharing, and applying such knowledge, has pursued those requirements of companies and been studied by many researchers and consultants, especially focusing on the Knowledge Map'. It is said that a knowledge map is a powerful tool for scanning and managing the knowledge that exists in a company and that it is the most important part of establishing a knowledge management base. Until now, however, there have been no specific or practical models for establishing a knowledge map, in spite of the concern. For this reason, this paper suggests a practical model for establishing a knowledge map in terms of a knowledge acquisition procedure based on the traditional research concerning concept maps. In addition to this, for examining the validity of the model, a case study on the 'P' steel and iron company has been performed. This paper's methodology on developing a knowledge map and the procedures to apply them to the real business environment will suggest a cornerstone in the field of practical implementation of knowledge management.

The purpose of this paper is to explore the possibility that green tourism involving traditional local foods could help reinvigorate local economy. The author examines some examples of developed countries to develop tour programs of the rural community and systematizes the local cuisine of Gwangju and Chonnam provinces. The source materials for this research include the data from the Office of Rural Development and interviews with the people concerned in June to July, 2005. The author starts with the literature review of written documents from various sources including the government, the Chonnam local government, periodicals and the internet. It seems necessary that we develop green tours involving unique local cuisines. To that purpose, the author claims that a variety of programs should be developed; (i) a public demonstration of traditional local foods, (ii) a hands-on experience program in which people can learn and cook by themselves, (iii) a tasting program of organic food and chemical-free produce, (iv) a program developing well-being food, and (v) lectures on healthy foods. The development of such green tours connected with the local cuisine will help vitalize the local economy and maintain tradition of the local cuisine.

The purpose of this study was to investigate high school students' interest on minerals and rocks. Seven hundred and eighty three students from four different regions (i.e., Seoul, Kyunggi, Chungbuk and Jeju) participated in this study. The results can be summarized as follows: (1) The students have somewhat low interest about minerals and rocks. In addition, the students lose the interest because they have been forced to learn minerals and rocks theoretically. (2) Girls' interest on minerals and rocks was higher than that of boys.

Since elementary school students are in the concrete operational stages, they have to learn mathematics using intuitive methods. So teachers have to have knowledge on the intuition. In this paper we investigated specialized content knowledge on the intuition which have 8 elementary school teachers in problem solving process. They were asked to solve 8 problems in the questionnaire which were provided by the www.mathlove.net. As a result we found that 7 elementary school teachers have a lack of understand on the intuition in problem solving process.

Since educating all students in learning how to learn and iic\il- to adapt thernselves to the changing society is the most desirable :.:.il:ii of education in the modern world, it is necessary that the library hc:one an increasingly important part of the students' learng activities. The development of the desire and necessary skills to seek mi! to acquire lino~vledge should be encouraged and planned by the acac:e:liic library. The effective instruction in the use of academic lihra1.1.- can provide the students with the cspxbility to carry on their own icL,i.!nal education through their life. This paper is to make a brief trace of the development of liGl-ary instruction in American universities and colleges oiyer the decades, providing the overview of many successful components of saxe representative projects and experiments, from which to clarify coi~in;on problems and principles involl-ed in them. Any one of standard approaches so far identified has turned o:lt to be not a perfect method in that each has its own merits and pl-oblcms. It may be that the process of analysis and evaluation is 1-aluab!e for better comprehensive perspectives in future program of the instr~iction in the use of academic libraries. An effort is sincerely made to giie an impetus to the recogrriiivn of the importance of library instruction in Korean academic .yorid to meet the urgent needs of the modern society.

Angiogenesis, the formation of blood vessels, is essential for preparing a closed circulatory system in the body, and for supplying oxygen and nutrition to tissues. Major diseases such as cancer, rheumatoid arthritis, and atherosclerosis include pathological angiogenesis in their malignant processes, suggesting anti-angiogenic therapy to be a new strategy for suppression of diseases. However, until the 1970s, the molecular basis of angiogenesis was largely unknown. In recent decades, extensive studies have revealed a variety of angiogenic factors and their receptors, including vascular endothelial growth factor (VEGF)-VEGFRs, Angiopoietin-Tie, Ephrin-EphRs and Delta-Notch to be the major regulators of angiogenesis in vertebrates. VEGF and its receptors play a central role in physiological as well as pathological angiogenesis, and functional inhibitors of VEGF and VEGFRs such as anti-VEGF neutralizing antibody and small molecules that block the tyrosine kinase activity of VEGFRs have recently been approved for use to treat patients with colorectal, lung, renal and liver cancers. These drugs have opened a novel field of cancer therapy, i.e. anti-angiogenesis therapy. However, as yet they cannot completely cure patients, and cancer cells could become resistant to these drugs. Thus, it is important to understand further the molecular mechanisms underlying not only VEGF-VEGFR signaling but also the VEGF-independent regulation of angiogenesis, and to learn how to improve anti-angiogenesis therapy.

Various method of insetting the transverse rectus abdominis myocutaneous flap for breast reconstruction has been reported in literature. The Bostwick's principle is commonly applied, which utilizes contralateral pedicle in a vertical or oblique flap inset position and ipsilateral pedicle in the transverse position. But it is relatively a complex and difficult technique, thus requires a more simplified strategy. We have formulated a new insetting method, in which the contralateral pedicled TRAM flap with an oblique($0^{\circ}-90^{\circ}$) flap inset was carried out. We used this method in 100 cases from July 2001 to June 2003. This maneuver places Hartrampf's zones I and III with good vascularity in the medial side, and zone II in lateral side of breast. Fat necrosis was observed in 14 patients(14%) and of these, only three cases needed surgical excision. This simplified method is easy to learn. Specifically, fat necrosis removal is easy with more tolerable aesthetic results, especially in Asian patients with smaller breasts.
