This study explored types and characteristics of South Korean crossover picturebooks that are enjoyed across generations. Participants included three publishers, six critics, six illustrators and three picturebook researchers, and focused on 92 South Korean recommended picturebooks published from 1995 to 2014 as the research material for this study. The majority of Korean crossover picturebook type was story, followed by information and art. There were few wordless books. Common themes of the story picturebooks were contemplation, traditional culture, social changes (such as immigration and redevelopment), reminiscence, social relations, loss and death, family problems, and social incidents. Classic essays and novels were revised for picturebooks as were famous poems originally written for grown-ups. Informational books were about traditions in music, architecture, furniture and special occasions like wedding and ceremonies. The style of the drawings were precise and realistic. Some drawings were done by brush and Chinese ink on hanji (traditional Korean paper) or silk. Some books featured Korean calligraphy as well, enabling adult readers to also appreciate the beauty and delicacy of the books. Art books and wordless books were quite rare and exhibited a playful tone. Adults alone were not presumed to be the primary reading audience of the picture books. Implications were made for picturebook marketing in a society such as South Korea, where the elderly population is rapidly increasing. Various forms of art books and parodies were also welcome. One conclusion of the study was that more experimental and innovative works would be encouraging for the development of South Korean crossover picturebooks.

The purpose of this study was to identify caregivers of the elderly, the pattern of the caregivers' caring behaviors, and the cultural principles of patterns of caring behaviors practiced in a Korean minority community, Yanbian. To clarify these, an ethnographic approach was used. The fieldwork for this study was conducted from Aug. 24, 1993 to May 20, 1994. The informants were 16 natives, age 60 or more, who were members of a large family of three generations. The results of the study are as follows. The caregivers for the elderly were family, kinship and community groups. Family caregivers for the elderly were spouses, sons, daughters-in-law, grandchildren, sons of former wives, sons of former husbands, adopted sons. daughters and sons-in-law. The elderly had caregivers who were part of the kinship group. Three community groups provided care for the elderly. The three community groups were Dokbozo. a formal large organization for the elderly. the same age group as an informal small meeting for the elderly, and other community younger groups. The findings of this study indicated that family caregivers, especially spouses and sons, are the significant others of the elderly, and comminuty groups are better caring groups than kinship relatives. This study identified forty-three different kind of caring behaviors. They were divided into fifteen behavior patterns. These patterns integrated into five categories : soo-bal(¼?¹ß), protecting, respect, support, jung(?×). For physical comfort, soo-bal and protecting were conducted. For the comfort of mind, respect. support, and jung were conducted. The comfort of mind are better than physical comfort for the elderly. Cultural principles of caring behaviors were group membership, reciprocity, and harmony. But there was no hierarchy priciple. And these three principles provide best caring together at the same time. This study provides significant data for nursing research, theory and practice.

Dysuria has been mentioned several times in "Treatise on cold" and "Golden Chamber" of Zhang Zhong-jing in Han Dynasty. This article makes a detailed discussion of etiology, pathogenesis, treatment and prescription of Dysuria from three periods that is Han and Tang Dynasty, Song and Yuan Dynasty, Ming and Qing Dynasty. It has demonstrated the inheritance, development and innovation of academic ideas of later physicians from Zhang Zhong-jing, which enriched and developed the theory of Zhong-jing.

Using 23 867 standard essential patents claimed for three different wireless telecommunication standards (GSM, WCDMA, and LTE), this research examined the difference in technological importance and breadth of patents between practicing and non-practicing entities. We discovered that compared to manufacturers and service providers, organizations who do not appropriate innovation-derived profits directly from product or service markets tended to have relatively low-quality but broadly scoped technologies for the claimed standard essential patents. These relationships between the characteristics of inventions and the organizational types were consistently held across different generations of wireless standards as indicated by regressions run for each sample split by generation. Furthermore, the theory and policy implications of our results and arguments are presented herein.

According to Wayne A. Wiegand in the 1998, he research to The "Amherst Method": The Origins of the Dewey Decimal Classification Scheme. Although a debate about the origins of the Dewey Decimal Classification Scheme has been going on for generations, historical consensus remains elusive. This paper contributes information to the historiography on the origins of the scheme: 1) by grounding an account of Dewey's thinking as he was crafting the DDC on an analysis of a large body of sources than previous classification historians have consulted; and 2) by expanding and deepening historical understanding of the contextual forces influencing on the classification structure. Because the DDC idea as it first occurred to M. Dewey in Amherst in 1872-73 is an important in the history of library development in the world. He outlined the first draft of his decimal scheme and submitted it to the Amherst College Library Committee on 8 May 1873. This paper analysis to "Three Genetic Paper", that is 1) The Merits of the System, 2) Library Classification System, 3) Its Special Adaption to our Library.

Purpose: Animal models of a chronic wound are yet to be fully developed, and animal studies on this subject has yet to take place. The purpose of this study is to create the foundation for research on chronic wound healing based on a swine model, the most similar to that of a human. Methods: Three female 2-3 month old 'yolkshires' were used. Total of eight full thickness skin defects, $6{\times}3cm$ sized, were created on the back of each pigs. Three groups were created for comparison; Group I (n=4) was left as they were after full skin thickness excision, while the excised tissues of Group II (n=3) were turned inside out and sutured so that the epidermis would come in contact with the fascia. Group III (n=3) were excised full skin thickness in depth and silicone blocks were implanted in them. Dressing was not practised so that the wounds would be vulnerable to infection. Results: In Group III, the skin contraction rate was the least among the three groups for each three weeks of observation respectively. Also during the three weeks, bacteral colonization was at the highest among the comparison. On the third week, inflammatory cells were still active, but the generations of epidermis and collagen synthesis were detected minimally. Conclusion: The Group III was relatively the most similar model of chronic wounds. and modification of the silicone blocks, could provide us with a very effective chronic skin wound model similar to human.

Synthesis and properties of novel excited-state intramolecular proton transfer (ESIPT) materials recently developed in our group are described. Highly efficient ESIPT in polymeric system has been investigated theoretically and experimentally with a semi-rigid polyquinoline (PQH, PQDH) possessing an intramolecular tautomerizable hydrogen bond. Poly(aryl ether) dendrimers of three different generations that are cored with photo-tautomerizable quinoline (QGn, n=1,2,3) were also synthesized and characterized to investigate the effect of dendritic architecture on the ESIPT activity. Stimulated emission and amplified spontaneous emission in these organic materials system are discussed in terms of ESIPT activity.

Reverse Design(RD) plays an important role in simulation engineering, such as CFD (Computational Fluid Dynamics) and Virtual Engineering and Design. RD becomes much more valuable when there is no shape data of the practical models for CFD grid generations. In this study, two-camera based rapid prototyping(RP) system is proposed. 3D-PTV based measurement algorithm was adopted. The developed system was applied to reconstruct three-dimensional data of a human face, a motorcycle model, a cylindrical body and a triangular pyramid.

Structural interpretation by using subsurface attitude of coal seam and outcrop patterns of folds and faults shows that wrench and thrust tectonics took place simultaneously in the study area. From the interference patterns of fold axes, three generations of folding are suggested: $F_1$ (NE-SW), $F_2$ (N-S), and $F_3$ (E-W). Differential displacement of rock mass from north to south yields to E-W fold and Osypcheon Fault. Geometry of subsurface coal seam show different patterns comparing to those of surface outcrop because of shallow-depth crustal shortening which took place post Cretaceous.

During meiosis, homologous chromosomes (homologs) pair and undergo genetic recombination via assembly and disassembly of the synaptonemal complex. Meiotic recombination is initiated by excess formation of DNA double-strand breaks (DSBs), among which a subset are repaired by reciprocal genetic exchange, called crossovers (COs). COs generate genetic variations across generations, profoundly affecting genetic diversity and breeding. At least one CO between homologs is essential for the first meiotic chromosome segregation, but generally only one and fewer than three inter-homolog COs occur in plants. CO frequency and distribution are biased along chromosomes, suppressed in centromeres, and controlled by pro-CO, anti-CO, and epigenetic factors. Accurate and high-throughput detection of COs is important for our understanding of CO formation and chromosome behavior. Here, we review advanced approaches that enable precise measurement of the location, frequency, and genomic landscapes of COs in plants, with a focus on Arabidopsis thaliana.
