We propose that, in order to control the inflation and general instability associated with the least squares estimates, we can use the ridge estimator $$ \hat{B}^* = (X'X+kI)^{-1}X'Y : k \leq 0$$ for the regression coefficients B in multivariate regression. Our hope is that by accepting some bias, we can achieve a larger reduction in variance. We show that such a k always exists and we derive the formula obtaining k in multivariate ridge regression.

Sequential test plans are characterized by decision rules for accepting or rejecting compliance, or continuing the test at my test time. They are determined by selected values of risks and discrimination ratio. The sequential test plans in the international standard such as MIL-HDBK-781A are based on the assumption that the underlying distribution of times between failures is exponential. In this paper, sequential test plans are extended to the Weibull distribution case. Simulation studies are performed to examine the reasonability in this extension.

This paper examines the relationship between architecture of the past and architecture of the present, and suggest that necessity to reinterpret it in the context of today's architecture, rather than accepting the past architecture as its historical meaning. Such a condition, however, the architecture of the past works in another ways not in a historical ways that is generally perceived, and this paper suggest another interpretations in the meaning of past architecture and what significance it has.

In this study, we tried a study on a direction of the field of oriental medicine on accepting complementary alternative medicine by analyzing the related thesis, journals and papers on the complementary alternative medicine published in the field of oriental medicine. As the result of analyzing the present study of the field of oriental medicine on the complementary alternative medicine, there have been 22 studies on the complementary alternative medicine. Thesis, papers were mainly experimental papers about the bee venom therapy, energy therapy, fasting therapy, and colon therapy, and the journals were actively studied in order of clinical paper, experimental paper, and reference paper about the bee venom therapy, energy therapy, and reflexolgy. The acceptance of complementary alternative medicine by the field of oriental medicine through a scientific relation should be conducted more systemically by setting the main academy taking charge of the study on common characteristics of the complementary alternative medicines on the classification of NCCAM as well as the related academies taking charge of the study on the unique characteristic of each complementary alternative medicine. First, additional studies are needed to make the most of characteristics of each complementary alternative medicine through the main academy and the related academies, and for the next, additional studies are necessary to complement the research trend on each complementary alternative medicine through the main academy and related academies.

This study attempted to explore how middle aged married men and women prospected a Centenarian society and what implications their prospect cast for family policy. We conducted focus group interviews with five groups in order to identify their subjective prospects on marital relations, parent-child relations, caregiving from family or institutions, and alternative living arrangement. From those interviews, we found that married men and women in their 40s, 50s, and 60s possessed ambivalent attitudes toward their marital relationship, either acknowledging an importance of marital relationship or accepting long-standing disrespectful marital relationship. They also had a dualistic perspective on parent-child relationship, accepting parental responsibility for children and even grand-children but maintaining low expectations for children. What they needed was age appropriate opportunities for work or leisure and better community services and facilities. These results showed that the middle-aged was concerned experiencing unprecedented family situations. They needed family life education and services in order to adapt to the Centenarian society. Since family policy has viewed this age group out of service target, programs and services have been underdeveloped for this group. Expecting a Centenarian society however, we need to expand the boundary of family policy and take a new perspective. We need to develop and implement marital education programs, community-based self-care services, and age-appropriated opportunities for work, leisure, and social relations.

This paper examined the information literacy which is the concrete purpose of the ICT using education which appeared in order to elevate the effects of education in school after the introduction of the 7th educational curriculum. Based on TAM (Technology Acceptance Model) that provides useful theoretical foundations for analyzing the factors influencing acceptance and diffusion of IT, it determined the factors influencing the process of accepting the information literacy instruction as follows: perceived usefulness; perceived ease of use; attitude; effects of the information literacy instruction; teachers' innovation; school library relevance; school librarians' support; and the self-efficacy. This paper confirmed the influences of these factors on the process of accepting the information literacy through empirical study. Through this study, it intended to suggest the ways to activate of the information literacy instruction.

As a part of ${\square}$ project to discover Korean modern design and Korean modern an, this thesis is based on collaborated research with Musashino Art College about Teikoku Art College in Japan (renamed as Musashino Art School in 1948 and promoted as Musashino Art College in 1962) and Korean students of Teikoku Art College. In accepting modern art and design, Teikoku Art College. In accepting modern art and design, Teikoku Art College is important since most Koreans studied there to learn modern art and design. Especially, this focuses on activities of Korean students in Design (Zuan) program at Teikoku Art College and their relationships with professors to examine the influence of design study and acceptance through Teikoku Art College in Japan and the relationship with design education in Korean after the World War II. This research made it possible to renew the lists of 147 Korean students and 13 Korean students in Design (Zuan) program. Thus, this could be essential data to reconstruct the history of Korean modern design which has lacked basic documents.

This study examines the web-based education which is changing the educational paradigm itself according to the development of IT and the spread of Internet in the IT society and the information literacy which have been emerging as survival techniques. Based on Technology Acceptance Model that provides useful theoretical foundations for analyzing the factors influencing acceptance IT, it determined the factors influencing of accepting the information literacy instruction as follows: perceived usefulness; perceived ease of use; connectivity ; reactivity of web-based education ; job relevance: university library' support; ACRL standards and effects of the information literacy Instruction. This paper confirmed the influences of these factors of accepting the web-based information literacy instruction through empirical study. I have suggested factors affecting the acceptance of web-based information literacy instruction by Conducting positive researches on how these factors influence the acceptance of web-based information literacy instruction of university libraries.

This study proposes a risk analysis methodology for information system security management in which the complexity on the procedure that the existing risk analysis methodology is reduced to the least. The proposed risk analysis methodology is composed of 3 phases as follows: beforehand processing phase, counter measure setting phase, post processing phase. The basic risk analysis phase is a basic security management phase in which fixed items are checked when the information security system is not yet established or a means for the minimum security control is necessary for a short period of time. In the detailed risk analysis phase, elements of asset a vulnerability, and threat are analysed, and using a risk degree production table produced from these elements, the risk degree is classified into 13 cases. In regard to the risk, the 13 types of risk degree will execute physical, administrative, and technical measures through ways such as accepting, rejecting, reducing, and transferring. Also, an evaluation on a remaining risk of information system is performed through a penetration test, and security policy set up and post management phase is to be carried out.

In this study, the assessment and the factor analysis of the self-directed learning readiness for engineering students were conducted. As measurement tool was used the self-directed learning readiness scale of Guglielmino's SDLRS questionnaire in Korean translation. It was surveyed under 519 students of Faculty of Engineering of Korea University of Technology and Education. Responded questionnaires were 496. As a result, seven factors were identified: (1)openness to learning, (2)initiative and inquiring mind, (3)independence and basic learning skills, (4)creativity, (5)accepting responsibility for learning, (6)love of learning, (7)positive orientation of the future. And the scale was confirmed in validity. It was confirmed that the mean value of openness to learning and of love of learning were higher than average, while mean value of independence and basic learning skills, accepting responsibility for learning were lower than average, there was the difference in SDLRS by students' personal backgrounds, but there were statistically significant differences in seven factors.
