HOTAIR is an lncRNA that has been known to have an oncogenic role in different cancers. There is limited knowledge of genetic and epigenetic elements and their interactions for the gene encoding HOTAIR. Therefore, understanding the molecular mechanism and its regulation remains to be challenging. We used different in silico analyses to find genetic and epigenetic elements of HOTAIR gene to gain insight into its regulation. We reported different regulatory elements including canonical promoters, transcription start sites, CpGIs as well as epigenetic marks that are potentially involved in the regulation of HOTAIR gene expression. We identified repeat sequences and single nucleotide polymorphisms that are located within or next to the CpGIs of HOTAIR. Our analyses may help to find potential interactions between genetic and epigenetic elements of HOTAIR gene in the human tissues and show opportunities and limitations for researches on HOTAIR gene in future studies.

This study is to find the methods that BIBFRAME could accept the new concept of representative expression in the RDA Toolkit Beta which has developed in 2019. Research methods were the literature reviews and the mapping between RDA Toolkit Beta and BIBFRAME. BIBFRAME's acceptance of representative expression of RDA Toolkit Beta was suggested as followings. First, the properties of representative expression should be defined in BIBFRAME because the RDA Toolkit Beta defined the expression attributes and representative expression elements apart. Three choices for BIBFRAME's acceptances are (1) to develop the newly devised representative expression properties (2) to specify representative expression properties with using refinement (3) to differentiate representative expression properties with using class. Second, as relationship elements should be defined in BIBFRAME to link work and representative expression which transfer the expression attribute to work. This study will contribute to revise the BIBFRAME because this focusd on BIBFRAME's acceptance of RDA Toolkit Beta in which reflected LRM.

This study focuses on defining the new meaning of immateriality in the present times expressed on space. The purposes of this study were to examine the characteristics of immateriality showed in commercial interior design in Korea, based on the definition of immateriality concept and the analysis of the way it is expressed. The result of this study is as follows; it categorized characteristic of material expression, space concept and media. Characteristic elements can be classified into 6: transparency, implication, off-gravitation, ambiguity of boundary, temporality, interactivity. Expression of immateriality in commercial interior space was obtained in many different ways, which are identified: new expression of material by reduction of materiality, leveling of transparency, expression of floating status, changeable image, illusion effect, blurring boundary. Immateriality is deeply associated with the elements such as surface, material, media, light, and movement. So it is being recognized as an important design concept in today's pluralist society and will play an important role within the design paradigms for the future.

The purpose of this study is to draw out the features of expressions about Nature in Korean interior design, because the Nature has been being very important theme in the interior space. So, the 68 cases of domestic famous interior designers' works during last ten years were selected from authorized design magazines like as INTERIORS, MARU and so on. And next, the cases were analysed in according to interior image style, design elements used for effect of Nature and the direction of expression(directly or indirectly), As the results, composite expressions with a few elements were found in modern, hi-tech, elegant, minimal and casual styles, while direct expressions with many elements were found in natural and ethnic styles. And main elements for effect of Nature were trees and stones. Among many elements, water and stones became more important elements after 2000 than before. In the meantime the use of composite expressions was being increased and so appeared even in natural and ethnic styles.

This study proposes an evaluation item model for the avatar expression process, satisfaction and self-identification for each expression element in order to investigate the expression attributes on the influence on the user in setting the avatar. The evaluation of avatar expression method was composed of self-identification and satisfaction by ease of expression and expression elements on the avatar production and expression process. To evaluate the proposed evaluation model, 17 people participated in the experiment. As a result, it was found that most of the participants had a high level of understanding of the production process, and the more diverse the expression elements, the higher the satisfaction with the avatar expression process. Hair shape and face shape were the most important expression factors, and clothes and overall harmony was the most concerned facotrs. Most of them tried to express themselves as realistically as possible. However, in self-identification, there was no significant correlation between expression and production process. In this study identify the decision-making factors that appear in the avatar expression process, the direction in which satisfaction can be formed, and the factors that affect self-identification. In addition, it will be a basic study on how avatars have a lasting influence on users in the future.

The purpose of this study was to investigate that to see how their traditional characteristics were reflected and expressed in Hanoi vietnamese contemporary public restaurants. For this, We visited Hanoi twice to have onsite research in August 2012 and 2013. According to the results of surveying Vietnamese public restaurants, all of the 12 cases had humane characteristics reflecting Vietnam traditional culture, showing Vietnamese unique traditional characteristics including intangible elements such as natural environment, life culture elements such as food culture, and formative aesthetic elements using indigenous ornaments. Different from luxury restaurants that had trade names on the theme of historical stories related to people or places and expressed various concepts formatively using photographs of Vietnamese politics and history and ornamental elements such as tableware, however, the public restaurants were simple in theme or concept. It is probably because most of the surveyed cases were situated in the old quarter to the north of the Hoan Kiem Lake and in the area to the west of the lake and their target customers were local people, so they reflected the Vietnamese traditional residence style and common people's life rather than designing the restaurants intentionally with specific concepts. As to the spatial expression characteristics of the surveyed cases, casual restaurants in Hanoi expressed only basic structure using basic construction materials and techniques with outdoor spaces in the form of Vietnam traditional tube house, and therefore, the overall atmosphere was contemporary. In indoor spaces as well, the general level was low, using uncharacteristic common design and color and cheap finishing materials and furniture. 83% of all cases showed the pattern of VM-VM-VT, being mainly contemporary by partially adopting Vietnamese unique ornamental elements for their outdoor and indoor spaces and using traditional elements supplementarily.

Introduction Cellulose microfibril is a major cell wall polymer that plays an important role in the growth and development of plants. The gene cellulose synthase A (CesA), encoding cellulose synthases, is involved in the synthesis of cellulose microfibrils. However, the regulatory mechanism of CesA gene expression is not well understood, especially during the early developmental stages. Objective To identify factor(s) that regulate the expression of CesA genes and ultimately control seedling growth and development. Methods The presence of cis-elements in the promoter region of the eight CesA genes identified in flax (Linum usitatissimum L. 'Nike') seedlings was verified, and three kinds of ethylene-responsive cis-elements were identified in the promoters. Therefore, the effect of ethylene on the expression of four selected CesA genes classified into Clades 1 and 6 after treatment with $10^{-4}$ and $10^{-3}M$ 1-aminocyclopropane-1-carboxylic acid (ACC) was examined in the hypocotyl of 4-6-day-old flax seedlings. Results ACC-induced ethylene either up- or down-regulated the expression of the CesA genes depending on the clade to which these genes belonged, age of seedlings, part of the hypocotyl, and concentration of ACC. Conclusion Ethylene might be one of the factors regulating the expression of CesA genes in flax seedlings.

In this paper, both an approximate expression and an exact expression for the contribution factor of an element to the natural frequency of the finite element discretized system of a structure in general and a membrane in particular have been derived from the energy conservation principle and the finite element formulation of structural eigenvalue problems. The approximate expression for the contribution factor of an element is used to predict and determine the elements to be removed in an iteration since it depends only on the quantities associated with the old system in the iteration. The exact expression for the contribution factor of an element makes it possible to check whether the element is correctly removed at the end of an iteration because it depends on both the old system and the new system in the iteration. Thus, the combined use of the approximate expression and the exact expression allows a considerable number of elements to be removed in a single iteration so that the efficiency of the evolutionary structural optimization method can be greatly improved for solving the natural frequency optimization problem of a structure. A square membrane with different boundary supports has been chosen to investigate the general evolutionary path for the fundamental natural frequency of the structure. The related results indicated that if the objective of a structural optimization is to raise the fundamental natural frequency of the structure to an optimal value, the general evolutionary path during its optimization is that the elements are gradually removed along the direction from the area surrounded by the contour of the highest value to that surrounded by the contour of the lowest value.

Currently, the development and sale of various emoticons has given users a wider range of choices, but a systematic and specific approach to the recognition and use of emoticons by actual users is lacking. Therefore, this study tried to investigate the subjective perception and visual attention concentration of actual users on negative emotional expression emoticons through a survey and eye tracking experiment. First, as a result of subjective recognition analysis, it was found that emoticons are frequently used because their appearance is important, and they can express various emotions in a fun and interesting way. In particular, it was found that emoticons that express negative emotions are often used because they can indirectly express negative emotions through various and concretely expressed visual elements. Next, as a result of the eye tracking experiment, it was found that the negative emotional expression emoticons focused on the large elements that visually emphasized or emphasized the emotional expression elements, and it was found that the focus was not only on the facial expression but also on the physical behavioral responses and language of expression of emotions. These results will be used as basic data to understand users' perceptions and utilization of the diversified emoticons. In addition, for the long-term growth and activation of the emoticon industry market in the future, continuous research should be conducted to understand the various emotions of real users and to develop differentiated emoticons that can maximize the empathy effect appropriate to the situation.
