Purpose: This study attempted to provide the basic data for the institutional improvement of the clinical practice of physical therapy department students. Methods: Research for this study included 390 participants used for the analysis of the present study. The statistical analysis was of the characteristics and satisfaction of the clinical practices of subjects, the reasons for major employment preferences before and after clinical practices, and the preferred institution and field of major employment before and after clinical practice. Results: The general characteristics of students of the physical therapy department include females in their third year of college at age 20~24 years-old. As well, no religion, usual satisfaction with major, and motivation of choosing a physical therapy employment rate were the most common. A residency type in the form where one would cook one's own food and a clinical practice with a general hospital grade were seen most often. Regarding preference of major employment before and after clinical practice, the preference of major employment was 88%, which increased by 5.2% after clinical practice from 82.8% before clinical practice. The preference for no major employment due to lack of interest and no aptitude increased 43.5% from 23.9% after clinical practice. Conclusion: The number of apprentices will increase despite practice institutions being limited; for practice of environment, content, etc., relatively changes are slow, and progress rapidly medical technology. It is a society in which expertise is required; in the present study, there is a value in providing the clinical data missing in physical therapy.

항공기의 설계 안전성을 보장하기 위하여 형식증명을 받아야 한다. 형식증명을 받은 항공기의 설계가 중대하게 변경되는 경우, 형식증명을 새로 받거나 개정형식증명 또는 부가형식증명을 신청하여야 한다. 국제민간항공기구, 미국 및 유럽의 인증 규정에서 부가형식증명 대상이 되는 설계변경에 대하여 매우 추상적으로 정의하고 있으므로, 본 논문에서는 설계변경에 관한 세계 각국의 인증절차와 인증사례를 분석하여 부가형식증명 대상이 되는 "광범위하지 않은 중급 설계변경"을 판단하는 기준을 제시하였다.

The purpose of this paper is to survey the major elements that have changed English from a synthetic language to an analytic one. Therefore, this paper has looked at the differences between synthetic languages and analytic ones. In synthetic languages, the relation of words in a sentence is synthetically determined by means of inflections, while in analytic languages, the functions of words in a sentence are analytically determined by means of word order and function words. Thus, Old English with full inflectional systems shows the synthetic nature. However, in the course of time, Old English inflections came to be lost by phonetic changes and operation, which made English dependent on word order and function words to signal the relation of words in a sentence. The major phonetic changes that have shifted English are the change of final /m/ to /n/, the leveling of unstressed vowels, the loss of final /n/, and the decay of schwa in final syllables. These changes led to reduction of inflections of English as well as the loss of grammatical gender. The operation of analogy, the tendency of language to follow certain patterns and to adapt a less common form to a more familiar one, has also played an important role in changing English.

The results of the research were as follows: The entire space of the village was based on natural formation in its initial formation stage. The traditional location conditions and environment were equipped with the possibility and conditions for the development of the village. Spatial boundaries were mostly divided by natural topography. The quantify of lots diminished in spatial structural factors, while the division of roads by hierarchy in terms of size became explicit. Alleys, as the minimum hierarchial nit, were degraded. The residence unit was focused on economic efficiency. Communal use facilities showed an external relations trend as central facilities. The land, unit residence and communal facilities approached the high hierarchial roads. The communal facilities showed relatively higher independence compared to the residence units. The spatial structural changes followed traditional life style in the initial stage of village formation; however, social elements mainly impacted on the changes. Since reform opening, economic elements were major causes of changes, while construction conditions, life style, and awareness of structures impacted upon the changes. Thus, the economic element is the major change element in the Korean Villages, even though other elements will also become diverse.

Purpose: This study aims to be used as a reference for setting the direction of university major education & policy. Research design, data and methodology: The satisfaction survey were nine major curriculum surveys for each college, targeting students enrolled in a university. One university consisted of 9 colleges and 49 departments or majors. The survey period is approximately one month. Results: The highest item in the major curriculum reflects the educational goal of the department, with a score of 3.95. Conversely, the lowest item is 3.65 points, indicating that the major curriculum offers a wide range of subjects to choose from. As the questions are higher than the average score (3.83 points), the major curriculum is helping me grow my competency through academic achievement (3.90 points), the major curriculum is helping me set my career and finding a job (3.88 points), The major curriculum suggests specific performance standards for judging the achievement of a set target competency (3.88 points), and the major curriculum reflects social demands and changes (3.85 points). Conclusions: Students want that their major education faithfully reflects the educational goals of their major and that major education helps their ability to grow for academic achievement.

We investigated the changes in the species of the woods used for Korean ancient and historic architectures, which include prehistoric excavated relics and existing wooden buildings in South Korea. The species data were collected from various sources such as excavation and repair reports, journal papers, and a few unpublished documents. We divided the building Periods as Paleolithic, Neolitic, Bronze Ages, Iron Age/Three Kingdoms, Koryo, Joseon (early, middle, late) and modem periods. In prehistoric periods, hardwoods were major species. Oak (Quercus spp.) woods dominated (94 percent in average); the others (5%) were Juglans mandshurica, Platycarya strobilacea, Castanea crenata, and few softwoods(1%). During Iron Age and Three Kingdom periods, oaks remained as a major species (57%) and others Platycarya strobilacea(21%), Castanea crenata(13%), and Pinus spp. (6%). The oak woods decreased in Koryo period and they occupied only 1.1%. Instead of oaks, pine (Pinus spp., 71%) and Zelkova serrata (22%) dominated in Koryo. In early and middle Joseon periods, pine woods (73%) remain as a major species and the others were oaks (14%) and Zelkova serrata (9%). As late Joseon came, the pine woods occupied more than 88%. In the late 19th and early 20th centuries, a few boreal species such as larch (Larix spp.) and spruce (Picea spp.), which grow in cold area, were found. We believe they were transported from northern Korea. The existing buildings in Korea are mainly from Joseon period and a few from late Koryo periods. During these periods, pine woods were used for most buildings. For such reason, pine woods were known as 'representative materials for historic buildings'. but earlier times, broad-leaved trees, i.e., oak and Zelkova woods were major materials. The changes in building materials resulted from both climate and human impacts. The dry climate and disturbed forests induce more pines in the mountains. We also compared the wood qualities of the species and found that Zelkova woods were superior ones and deserved more planting for future demands in the repair for historic buildings.

These studies were undertaken to investigate changes of major components occuring during germination of sesame (Sesamum indicum L.) seeds, Changes of total lipid and protein contents, and fatty acid composition were determined. Also, the correponding values of various components in cotyledons, hypocotyls and roots were measured according to germination stage. The results were summarized as follows; During germination, total lipid and protein contents decreased. In particular, protein contents rapidly decreased to the 3 days after gemination(DAG), and then total lipid contents rapidly decreased. In changes of total lipid and protein of cotyledons, hypocotyles and roots detected at the 10, 15 and 20 DAG, some variations were determined. The contents of lipid and protein in hypocotyls rapidly decreased, but since than no changes were observed. In contract, in roots similar changes patterns were observed, while since 15 DAG a rapidly increase was wxamined. In fatty acid composition of total lipid ,saturatedmfatty acids such as palmitic acid increased during the germination. On the other hand, unsaturated fatty acid such as olic acid and linoleic acid decreased during the same periods. In changes of fatty acid composition of total lipid of cotyledons, hypocotlys and roots, saturated fatty acids such as palmitic acid and stearic acid increased during the germination. However, linoleic acid decreased during the same germination suggesting that this may be due to the rapid degradation. However, linoleic acid decreased during the same periods. According to SDS-PAGE analysis, there was no detectible polypeptide bands on the gel before seed germination suggesting that this may be due to the rapid degradation of the storage peotein in the mature seed by hydrolytic enzymes during the stag. As germination continued polypeptide bands, one with 40KD, two with 32∼34Kd and one with 24KD, were detected on the gel.

Ultrastructural changes of the protein bodies in Glycine max during early germination were studied. There were no major morphological changes in protein bodies within 3 days after the imbibition, but from the 4th day the expanse of protein bodies could be observed. In subsequent stages, the aggregation of protein bodies coalesced into a large mass and then less electron-dense material in the central part of the cell. At last it bacame highly vacuolated.

In modern society, rapid environmental changes are occurring due to the complex interaction of various factors. Starting in 2020, the social environment is changing rapidly due to the impact of the pandemic, and the social and economic living environment is changing significantly not only in Korea but also internationally. In this trend, behavioral and spatial changes are occurring in response to changes in the architectural living environment. To analyze changes in behavior and space from an architectural perspective in response to changes in the social environment, first organize the concept and aspects of the pandemic that caused the change, examine the theory of the pandemic, and examine architectural responses to changes in the social environment. There is a need to analyze. Therefore, in order to architecturally review changes in the social environment due to the pandemic, the purpose of this study is to analyze the living behavior and space of major highrise residential complexes in the living environment and present new spatial alternatives in response.

Two piston cores (94PC-2 and 95PC-4) taken from the East Sea (Sea of Japan) are studied to evaluate the paleoceanographic changes and its interaction with climatic variation. The bulk geochemistry of the non-biogenic fractions of 54 sediment samples is determined using X-ray fluorescence. Four geochemical stratigraphic units at both core sediments are recognized based on the variations in major element concentration. These chemical stratigraphic units correspond well with the sedimentological and paleontological facies. Source materials are considered as basic and/or intermediate rocks judging from silica content. A distinctive boundary around 11 kyr may correspond to Younger Dryas event. The switch of most major elements at this level and the distinctive changes in concentration of typical terrigenous elements (TiO$_2$ and Al$_2$O$_3$) are the strong evidence for the difference in sources of terrigenous materials. The weathering indices exhibit high degree in Core 94PC-2 and low degree in Core 95PC-4. The changes in weathering degree can be distinguished by the lowest value occurred at 11 kyr in Core 94PC-2 and by a gradual decrease from top to bottom in Core 95PC-4. The profiles of potassium and sodium exhibit specific excursions between the Holocene and the late Pleistocene. This implies that sediments of the two cores originating from different sources with different weathering degrees. The distinct two-group distributions in K$_2$O/CaO vs. Na$_2$O/K$_2$O also support the difference in provenance of aluminosilicate materials at the boundary of 11 kyr. Thus, supply patterns of terrigenous materials are stable in Holocene and more complicated in the last glacial period.
