During the last three decades power electronics has gone through energetic technical evolution. The technical needs from wide area such as in industrial, commercial, consumer, aerospace and environmental applications have driven the environment favorably for the power electronics. In the future, two extreme technology-expansion trends are expected: one into low power, and the other into very high power. The former is based on the high frequency and the circuit miniature using VLSI circuit and surface mounting aiming for the system-on-chip (SOC) technology. The latter includes the application areas of power utility such as HVDC, FACTS and SVC and large science area of electrophsycal apparatus such as thermonuclear fusion, acclerators, and electric guns. This paper describes the technology status of some major elements which are available today and the key roles of the power electronics from view points of applications. The author would like to take this opportunity to raise discussions about the future technology development trend of power electronics in our country with the fellow power electronics engineers.

MicroRNAs (miRNAs) are known for their role in mRNA silencing via interference pathways. Repetitive elements (REs) share several characteristics with endogenous precursor miRNAs. In this study, 406 previously identified and 1,494 novel RE-derived miRNAs were sorted from the GENCODE v.19 database using the RepeatMasker program. They were divided into six major types, based on their genomic structure. More novel RE-derived miRNAs were confirmed than identified as RE-derived miRNAs. In conclusion, many miRNAs have not yet been identified, most of which are derived from REs.

The purpose of this study is to accumulate basic data to establish planning direction and planning factors for the environment-friendly apartment complex by clarifying general concept and mark of it. For this purpose, the field study has been conducted to the environment-friendly apartment complex in Korea and Japan. The major findings of this study are as follows; 1) The basic concept of planning factors for environment-friendly apartment complex are natural harmony, improvement of residents' health ＆ amenity, energy ＆ resources saving and response to the social change. 2) For Japan, the planning factors and technical elements for the environment-friendly apartment complex were applied in the whole range of apartment complex with various and positive methods. For Korea, on the other hand, application of the planning factors of energy saving, resources saving and minimizing environment pollution was insufficient.

Facing the aging society in Korea, the necessity of the facility for dementia patients is gradually increasing. This study is to understand the dementia and also to provide tile basic planning guideline in designing of the interior architecture of dementia ward. In designing dementia wards, following elements such as the behavior characteristic of dementia patients, living environment, individuality and community should be considered. The sauntering road of patients, patients' privacy, rest room, bathroom in ward designing for dementia patients should be understood. Material, color, lighting and furniture and so on as an intoner composition are also major elements.

This study is about finding out characteristic of recognition individual housing in seaside of Donghae. To accomplish this purpose, we survey the 150 houses related to the landscape. Thus the major analysis is to take basic data, such as image(modern, western, traditional, etc) about exterior form of housing corresponding to the landscape. The result summarized as follows First, the elements for the characteristic of recognition were exterior material finish, exterior color, roof type, roof material finish, window size, roof slope, area of wall vs roof. Second, the image of traditional housing was very insufficient to plan landscape of housing with design elements. This research suggests that landscape housing of future is to be environmental landscape design and the proper design is to be various considering not only user's preference but also control of landscape.

The Modern architecture, generally represented as Functionalism, had brought the important problems of the absence of cultural meaning and of the public alienation. Robert Venturi is one of the major architects who suggested the new theory of Architecture. Postmodernism, for solving these problems . Therefore the purpose of this study is to analyze his design ideas and works especially for four residential projects : Vanna Venturi House, Guild House, Brant Johnson House and Brant House, His design ideas are Complexity and Contradition, Symbolism. Ornamentalism and Pluralithy of meaning . The various historical and traditional elements are refereed as symbolic and ornamental elements. The symbolic and cultural meaning of architecture through their images, memories, and associations concerning historical motifs help communicate with the public . Robert Venturi tries to pursuit Populism in architecture through historical allusion and pop art.

Functional interpretation of noncoding genetic variants associated with complex human diseases and traits remains a challenge. In an effort to enhance our understanding of common germline variants associated with lung cancer, we categorize regulatory elements based on eight major cell types of human lung tissue. Our results show that 21.68% of lung cancer-associated risk variants are linked to noncoding regulatory elements, nearly half of which are cell type-specific. Integrative analysis of high-resolution long-range chromatin interactome maps and single-cell RNA-sequencing data of lung tumors uncovers number of putative target genes of these variants and functionally relevant cell types, which display a potential biological link to cancer susceptibility. The present study greatly expands the scope of functional annotation of lung cancer-associated genetic risk factors and dictates probable cell types involved in lung carcinogenesis.

Earthquake-induced pounding is one of the major reasons for structural failure in earthquake prone cities. An accurate description of the pounding phenomenon of two buildings requires the consideration of systems with a large number of degrees of freedom including adequate contact impact formulations. In this paper, firstly, a node to surface formulation for the realization of state-of-the-art pounding models for structural beam elements is presented. Secondly, a hierarchical substructure technique is introduced, which is adapted to the structural pounding problem. The numerical accuracy and efficiency of the method, especially for the contact forces, are verified on an academic example, applying four different impact elements. Error estimations are carried out and compared with the classical modal truncation method. It is demonstrated that the hierarchical substructure method is indeed able to significantly speed up the numeric integration procedure by preserving a required level of accuracy.

A new digital work environments, organizational changes, and system changes surrounding the records have changed the concept of records. ISO 15489, the international standard for records management established in 2001, has also been amended in 15 years to accommodate this. The study examines the characteristics of the revised ISO 15489, its elements and concept, in 2016. By comparing the old and new elements of ISO 15489 in detail, we intend to understand the nature of the revision and the basic framework of new standard.

The aim of this study is to a study on the effects of fertile women on the low fertility in Korea. It is designed to research a model and established hypothesis with emphasis on major variables based on theoretical discussions. However, the result of the study is as follows. Firstly, this brought in delivery avoid phenomenon thus resulting in lower delivery phenomenon. The government should propose reasonable solutions to persuade female personal value and important elements of delivery rate at the same time. Secondly, Patriarchal stereotypes weighting household labor to female traditionally pressures working female with double burden as dual stance of work and family worsen the delivery will. Such atmosphere within a family generates female with an ability to get pregnancy to avoid marriage and delivery. Lastly, the research has pointed out the delivery support policy as most ineffective policy among government policies. To solve this problem, the government policy to recover delivery rate must be reviewed continuously and to be exercised immediately.
