Coating immobilization is the process by which the wet coating applied to paper or paperboard reaches the final form. A coating immobilization point is defined as the solids content reached during drying where no further redistribution of coating materials occurs. Good control of coating immobilization is important in producing coated paper and paperboard with consistent high quality. This paper discusses the technical concepts of how coatings immobilize, and describes the importance of good immobilization control on coating holdout and coating structure. The use of soy protein polymers to modify the coating immobilization point is discussed. Soy proteins, because of their interaction with coating pigments, make a significant contribution to the immobilization characteristics of coastings. This technology gives the formulator options for changing the immobilization point to improve the performance of the coating. The importance of immobilization on casting uniformity, microporosity and sheet qualities is discussed, including binder migration, mottle, gluing, and print quality.

Modernity is commonly defined as a reflection of the features of modern society based on the historical experience of the West. As such, modernity includes involvement with political, economic, and social changes, a changing world-view, and changing trends in equality, gender roles, a desire for "the new," consumption, distribution based on mass production, and rational reform in fashion and dress. First and foremost, however, modernity in costume has been driven by the functional requirements of industrial capitalism. But while modernity has popularly been regarded as some sort of universal standard, in fact the West and the other societies have vastly different, unique, and particular experiences with their own respective histories of modernization. For this reason, cultural changes in the modernization process should be-indeed, must be-analyzed in the context of a country's own unique historical and cultural circumstances, rather than through the prism or strict adaptation of generalized Western concepts of modernization. Moreover, a "periodization" of the modernization of fashion and dress can be established by examining the characteristics of modernity in costume.

In this study of the relative effectiveness of constructivist and non-constructivist approaches to shadow activity for young children, 59 children in two kindergarten classes were assigned to constructivist or non constructivist conditions. Each group participated in 12 units covering shadow search, shadow making, changing shadow size, changing shadow position, and shadow disappearance. Analysis of covariance of differences between the mean scores of the two groups on the posttests of shadow concepts and scientific attitudes revealed that the children in the constructivist group performed better than the children in the non-constructivist group. This confirms the constructivist approach to shadow activities as good science activities for young children by promoting their active experimentation using reasoning about light to foster spatio-causal relations construction.

Current techniques of residential planning are based upon planning theories and experiences which have evolved over time. These techniques are prerequisite conditions in establishing a firm foundation upon which residential sites can be developed. Residential planning techniques, which have been introduced to Korea from such areas as Western Europe, North America and Japan, have been changing as a result of attempt to properly acculturate these foreign influences into a traditional, yet rapidly progressing Korean society. It has been this objective of Korean planners, of considering domestic conditions while incorporating planning experiences of other countries, that has spearheaded Korea's phenomenal development in recent times. In this study, the changes and perspectives of residential planning concepts are examined from a historically comparative point of view. This approach allows for a macroscopic perspective on the various theories of residential planning which are constantly changing.

Many tools in classical type for the production management have been used in industrial cells. In spite of their powerful logic and historical success, many appliers could not take but a little effectiveness in current economic conditions. The major reason is that the chronical production control methods are too narrow in its applicability to cover the problems occurred under such a high-speed changes. Therefore we need to develop the new concept of production management for the higher adaptability and outcome which can support vitablities to enterprises in severe condition. The essential points in changing the viewpoint of new production management concepts are valuable to the group of new management.

This is a study concerning about the definition of the concept of industrial heritage being mentioned often lately, and considering the term's origin and changing process aiming at clarifying and improving its undertone and understanding. Especially, it's a basic study to make people understand fundamentally what industrial heritage means and differences in Korea in where any innovative affair such as industrial revolution has never occurred. Looking into the origin and changing process of the industrial archaeology & industrial heritage terms, their concepts appear ambiguously defined due to their generational, phenomenal and terminological reason. but it's detectable that their subjects and timing range have been extended. Korea, China and Japan, the Asian nations also have gone through mainly phenomenal and terminological mess in accepting the terms. Korean industrial heritage can define from the definition of industrial heritage in Nyzni Tagil charter. It, however, have to redefine about period of industrialization. This study suggest the 4 steps of modern industrialization in Korea and insist that we have to conserve industrial heritages not only in colonial period but also in 1960-80 industrialization in korea.

This review article provides the trend of current nursing curriculum of todays in Korea and its perspectives. This article reviewed 5 aspects of the current nursing curriculum for the undergraduate program, those are the (1)educational philosophy and believes (2)the nursing concepts revealed in the current nursing curriculum (3)the educational goals and objectives (4)the framework of nursing curriculum (5)the syllabus and credit hours. The common nursing concepts in the current nursing curriculum are Nursing, Human being, Environment/society, Health, Nursing science. The examplary vertical concepts composing of the current nursing curriculum are nursing process, life styles and the horizontal concepts are client, health promotion /recovery /maintenance, leadership, and research. The common subjects composing of the nursing syllabus are the introductory subjects(nursing history, nursing professionalism, foundamental nursing), and the supportive subjects (communication, human relationship, human growth and development, health education, etc) and nursing research, the intrductory basic sciences (anatomy, physiology etc.), and the major nursing subjects (adult nursing, child nursing, maternity nursing, psychiatric nursng, community nursing, nursing administration.) In order to have more advanced nursing education, the suggestions were provided as follows : (1) It is necessary to have revision and evaluation of the process and the structure of the current nursing curriculum periodically. (2) The concept of health promotion for all human being should be integrated into the nursing curriculum. (3) The nursing education program should be unified into baccalauliate level to get one type of nurse-registration system. (4) The nursing courses will need to provide the necessary contemporary Informations to allow the nurses to fuction efficiently in this rapidly changing era.

Recent advancements in basic research on the process of secondary neurulation and increased clinical experience with caudal spinal anomalies with associated abnormalities in the surrounding and distal structures shed light on further understanding of the pathoembryogenesis of the lesions and led to the new classification of these dysraphic entities. We summarized the changing concepts of lesions developed from the disordered secondary neurulation shown during the last decade. In addition, we suggested our new pathoembryogenetic explanations for a few entities based on the literature and the data from our previous animal research. Disordered secondary neurulation at each phase of development may cause corresponding lesions, such as failed junction with the primary neural tube (junctional neural tube defect and segmental spinal dysgenesis), dysgenesis or duplication of the caudal cell mass associated with disturbed activity of caudal mesenchymal tissue (caudal agenesis and caudal duplication syndrome), failed ingression of the primitive streak to the caudal cell mass (myelomeningocele), focal limited dorsal neuro-cutaneous nondisjunction (limited dorsal myeloschisis and congenital dermal sinus), neuro-mesenchymal adhesion (lumbosacral lipomatous malformation), and regression failure spectrum of the medullary cord (thickened filum and filar cyst, low-lying conus, retained medullary cord, terminal myelocele and terminal myelocystocele). It seems that almost every anomalous entity of the primary neural tube may occur in the area of secondary neurulation. Furthermore, the close association with the activity of caudal mesenchymal tissue in secondary neurulation involves a wider range of surrounding structures than in primary neurulation. Although the majority of the data are from animals, not from humans and many theories are still conjectural, these changing concepts of normal and disordered secondary neurulation will provoke further advancements in our management strategies as well as in the pathoembryogenetic understanding of anomalous lesions in this area.
