A design parameter study is presented for the closed-loop type passive containment cooling system (PCCS) which is equipped with two heat exchangers: one installed at the inside of the containment and the other submerged in the water pool at the outside of the containment. A GOTHIC code model for PCCS performance analyses was set up and the design parameters such as the heat exchanger sizes, locations, and water pool tank volumes were analyzed to investigate the feasibility of installing this type of PCCS in PWRs like OPR-1000 being operated in Korea. We identified the size of the circulation loop and heat exchangers as major design parameters affecting the performance of PCCS. The analyses showed that the heat exchangers in the inside of the containment would be more influential on the heat removal capability of PCCS than that installed in the water pool at the outside of the containment. Hence, it was recommended to down-size the heat exchangers in the water pool to optimize PCCS without compromising its performance. Based on the parametric study, it was demonstrated that a closed-loop type PCCS could be designed sufficiently compact for installation in the available space within the containment of PWRs like OPR-1000.

This study analyzes the influence of the social and cultural background of Art Nouveau on the costumes, architecture, and crafts in the period drama 'Crimson Peak'. This research method captures images of women's costumes, architecture, and crafts in the 'Crimson Peak' and selects and analyzes those with a clear Art Nouveau influence. Edith's costumes are characterized by the Art Nouveau style that emerged in the 1890s, with an hourglass silhouette, pastel colors, soft materials, and organic curved embellishments. Lucille's costumes show characteristics that were prevalent before the 1890s, using bustles, strong colors, and elaborate ornamentation. The architecture is characterized by gothic vertical lines and organic curves, naturalistic patterns featuring animals and plants, and steel and glass materials. The crafts of 'Crimson Peak' are characterized by flexible shapes with strong, organic curves. These costumes, architecture, and crafts share formal elements including waving, twisting, and organic curves and plant-shaped motifs. The influence of social and cultural background of the age of Art Nouveau expressed in movies on formative arts was examined as impressionism appeared in costumes made of pastel colors, thin and see-through materials, medieval Gothic historicism expressed in structures composed of vertical design and religious relief ornament, exoticism appeared in Chinese vase and Japanese-patterned tea sets, naturalism with an animal·plant motif and phenomenon of active social activities of progressive women through women's clothing that elements of men's costume are introduced. This study will provide data for the production of period dramas set at the end of the 19th century.

In the case of a patients who have lost the centric stop and have a staggered occlusion of the residual teeth, various movements occur when the denture is loaded. Implant placement is necessary to reinforce the retention, support, and stabilization elements to reduce denture movement. However, in this case, considering the patient's age, aversion to surgery, and bone loss, implants were not placed and restoration was performed with a removable partial denture. In this case, it is important to set the correct mandibular position for restoration because the patient has a habit of chewing with the remaining teeth. In this case, a stable mandibular position was established using a gothic arch tracing, and good results were obtained by restoring with partial dentures, so this is reported.

One of the latest social trends is to reappear old things under the banner of the revival. It is easily found in the fashion industry because Fashion is not divided into the past, the present and the future thing but coexisting through all ages. The purpose of this study was to pursue the healthy and characteristic beauty of the modem people by understanding the beauty culture of the ancient. The Middle ages were mainly classified into Byzantine, Romanesque and Gothic by historical and cultural factors. In the Byzantine age, the clothing with rich silhouette was worn by the influence of the abstemious religion and it didn't express a specific proportion of human body. The people covered their hair with turbans and veils for the period. The Romanesque era was affected by the religious idealism and the Greek-Roman culture. The ideal proportion of human body could be 8 heads high and the clothes expressing natural silhouette of human body came out. Depending on the feel of the flowing texture, long-braided hair was typical in that time, and also wearing kinds of head dress as personal ornaments was characteristic in the age. In the period of Gothic, the long and weak human body was emphasized. The ideal proportion of human body could be figured with 8.5 heads high and it was expressed with the form of artificial and vertical silhouette such like tight-fitting upper garments, gathered skirts and long hats.

Safety and health related information for the proper use and handling of pesticides is usually printed on the surface of the pesticide products (bottle type or bag type) in the form of texts. But, the guidelines or standards for the appropriate presentation of the texts for the pesticide products are most vague or not practical. Thus, this study aimed to provide the preliminary guidelines for the text sizes based on the legibility experiments. Total twenty subjects from two age groups (young: n=10, old: n=10, five males and five females in each group) participated in the experiment. First, subjects read the text cards presented in the distance of 50cm from the eyes of the subjects. Eight different text card sets were prepared for different font type(thick gothic-type and fine gothic-type), thickness of font(plain and bold), and number of syllables (2 and 3 syllables). When subjects read the cards, the correctness of reading (correct or wrong) was recorded and the degree of discomfort (from 1: no discomfort at all to 4: can't read at all) was also evaluated for all the text sizes. Results showed that the character size should be 4 pt or larger for the young subjects to read at least one word correctly in all the text conditions. For the old subjects to read at least one word correctly, the character size should be five pt or larder. The average of the minimum character sizes for 100% correct answer is 6.1 pt for young subjects and 10.5 pt for old subjects, respectively.

In order to analyze the hydrogen distribution during a severe accident in the APR1400 containment, GASFLOW II was used. For the APR1400 NPP, a hydrogen mitigation system is considered from the design stage, but a fully time-dependent, three-dimensional analysis has not been performed yet. In this study GASFLOW code II is used for the three-dimensional analysis. The first step to analysis involving hydrogen behavior in a full containment with the GASLOW code is to generate a realistic geometry model, which includes nodalization and modeling of the internal structures such as walls, ceilings and equipment. Geometry modeling of the APR1400 is conducted using GUI program by overlapping the containment cut drawings in a graphical file format on the mesh view. The total number of mesh cells generated is 49,476. And the calculated free volume of the APR1400 containment by GASFLOW is almost the same as the value from the GOTHIC modeling. A hypothetical SB-LOCA scenario beyond design base accident was selected to analyze the hydrogen behavior with the hydrogen mitigation system. The source of hydrogen and steam for the GASFLOW II analysis is obtained from a MAAP calculation. Combustion pressure and temperature load possibilities within the compartments used in the GOTHIC analysis are studied based on the Sigma-Lambda criteria. Finally the effectiveness of HMS installed in the APR1400 containment is evaluated from the point of severe accident management

In this dissertation, a new off-line recognition system is proposed using a subgraph pattern, neural network. After thinning is applied to input characters, balance having a noise elimination function on location is performed. Then as the first step for recognition procedure, circular elements are extracted and recognized. From the subblock HT, space feature points such as endpoint, flex point, bridge point are extracted and a subgraph pattern is formed observing the relations among them. A region where vowel can exist is allocated and a candidate point of the vowel is extracted. Then, using the subgraph pattern dictionary, a vowel is recognized. A same method is applied to extract horizontal vowels and the vowel is recognized through a simple structural analysis. For verification of recognition subgraph in this paper, experiments are done with the most frequently used Myngjo font, Gothic font for printed characters and handwritten characters. In case of Gothic font, character recognition rate was 98.9%. For Myngjo font characters, the recognition rate was 98.2%. For handwritten characters, the recognition rate was 92.5%. The total recognition rate was 94.8% with mixed handwriting and printing characters for multi-font recognition.

A patient failed to use conventional complete dentures due to severe mandibular bone resorption and soft tissue hyperplasia on lips, tongue and oral vestibule from vascular malformation. The treatment of choice would be an implant-retained overdenture, however, he refused owing to high cost. The closed mouth impression technique using BPS principle, CR record registration with gothic arch tracing and monoplane occlusion using non-anatomic teeth were used to fabricate complete dentures for this patient. Patient satisfaction, the retention and the stability of complete dentures were highly improved as a result.

Coleridge's fame as a poet rests on the achievement of the mystery poems, "The Anceint Mariner," "Kubla Khan," and "Christabel." Coleridge's achievement in "Christabel" goes far beyond what previous critics have imagined. Coleridge is one of a handful of great writers who are included as representatives of androgyny. Throughout his life, Coleridge was accustomed to point out feminine qualities within himself. "Christabel" exemplifies the kind of writing contemporary feminist theories call l'écriture féminine. L'écriture féminine is not necessarily the creation of women but may rather be the works of those who refuse to identify with the father and the laws of paternal discourse. "Christabel" becomes Coleridge's most daring symbolic story. "Christabel" appears in its full significance as a vehicle for some profound insights into the dynamics of relationships between men and women, fathers and daughters. Through her deformity, Geraldine is actually the casualty of her father's hatred of women, and is the embodiment of all its anti-virtual aspects. The poem shows no bitterness against women, only compassion and remorse. Coleridge is sympathetically presenting Christabel's suffering as a woman at the hands of an overmastering man. Also, "Christabel" demonstrates woman power as well. In fact, the one person whose tales have any real effect within this narrative is the ambiguous Geraldine. Geraldine excels at story-telling, at making words act for her. Perhaps, despite the appearance of the surface, in which men hold all the cards, it is in fact women, or the feminine, so necessary to procreation and creativity, who hold sway here. This apparent dominion of the feminine derives at least partly from Coleridge's use of the conventions of that feminine genre, the Gothic romance. L'écriture féminine is a concept defined by its divergence from a dominant cultural norm. One may speculate that the fragmentary state of "Christabel" and "Kubla Khan" is in fact congruent with this mode of writing. If these poems imply a theoretical écriture féminine, they are by definition "incomplete," for completeness is a standard of patriarchal language and culture. More perplexing even than the other "mystery poems," "Christabel" is the true fragment of the three.

Support, retention, and stability of dentures are key factors in the use of complete dentures in edentulous patients. With the development of digital dentistry, attempts are being made to replace traditional treatment methods. Also, struggle to reduce the number of patient visits and to manufacture high-quality digitally fabricated dentures are ongoing. In this case, a digital denture was restored using a tray capable of obtaining centric relation through gothic arch tracing and a facial scan. By replacing the traditional complete denture restoration method, the number of patient visits was reduced and esthetic results with satisfactory denture support, retention, and stability were obtained.
