The purpose of this study is to identify the form and components, decoration and locality of pyongnangans(平欄干) in Yangban's Houses(32 Houses) in Gyeongbuk region, The results of this study, which were carried out through both survey and on-site study, are as below. First, Pyongnangans of Gyeongbuk region Yangban's Houses can be classified into 4 different types, which are (1)Mureum type, (2)Gyoran(交欄) type, (3)Mureum-Saldae combination type, (4)Simplified Saldae type. And these 4 types are again subdivided into eight types, depending on differences of both detailed form and framework. Gyoran type are the most common cases in Yangban's Houses of Gyeongbuk region, whose number is followed by the order of Mureum type, Mureum-Saldae combination type and Simplified Saldae type Pyongnangans. Decorative 亞 shaped Gyoran type are more set up in Sarangchaes than in Anchaes, and this was because Decorative Gyorans are more appropriate to show the Social status and class of a patriarch than humble Mureum type. Pyongnangans of Yangban's Houses in Gyeongbuk region have their peculiarities in the exclusion of decorativeity, by consistent use of plain single-layer Pyongnangans. A certain locality is reflected on the types and detailed forms of Pyonnangans. Mureum type are widely found in Gyeoungju region Yangban's Houses, while Gyoran type were more often used in Andong region. In Bonghwa region, Mureum-Saldae combination type are found in large quantities. This was due to the locational chateristics of Sarangchaes in Bonghwa region, which were usually built on steep slopes.

The purpose of this study was to investigate the proper combination of ensemble suit details for the body silhouette of elderly women. In this study, the principal component analysis was used to search for the proper combination of suit details for covering defects of body which has been changed unbalanced. The designs of evaluated suits were manipulated in 18 different kinds by the essential elements such as collars, neckline(round neckline, shirt collar, tailored collar), types of one-piece dress(pleats type, gather type, flare type), and opening(opened, closed). The data evaluated by a multiple ranking test was analyzed by mean, paired t-test, ANOVA and Duncan's multiple ranged test. The results were summarized as follows: In case of normal body type, it had complementary effects for upper body with closed round neckline jacket or shirt collar jacket, and for lower and the whole body with a combination of closed tailored collar jacket or shirt collar jacket with pleats or gored type one piece dress. The visual effect for elderly women's body shape was different in opened or closed jacket. And that enhanced by Jacket with collar.

Steam generator tubes experience widespread degradations such as stress corrosion cracking, wear, tube rupture, denting, fatigue and so on. The resulting damages can cause tube bursting or leak of the primary water which contains radioactivity Therefore the allowable size of the damage is required to be determined on the maintenance purpose. The burst pressure of a tube with a T-type combination crack consisting of longitudinal and circumferential cracks is obtained experimentally and analytically. Fracture parameters such as stress intensity factor and crack opening angle are investigated. Also the burst pressure for a T-type combination crack is compared with that of a single longitudinal crack to develop a length-based criteria.

The Characteristics of space are determined by several factors; however, the element that determines the physical characteristic of floors, walls, and ceiling is the structure. This study constructs a wall to analyze the direct effect that the layout of an exhibition wall has on the element of the wall followed by the structural process and visibility of descriptive analysis and examples of art museums that the shift from a perceptional wall to an experiential wall affected circulation. For elements and formation methods of the wall, first, it is made up of open and closed type exhibition spaces, and it can give abundance in qualitative space rather than a quantitative aspect. Secondly, the directivity of space changes according to the development of the visible axis, thus, directly affects the change in visibility. Thirdly, the difference between spatial structure and visual structure is the difference between the visual axis and spatial structure. The wall formation type followed by the combination method, the simple visible structure, which is the type that possesses the simple combination (Room, Zone, Cluster), repeatedly uses the same size of units of space that is orderly and has few spatial axes and the classification of simple type and simple cluster type, which has few visible axes, also exists. Also, with the complex structure of the maze type it displays the reiterated form of the cluster, which is the space with disorderly combination and has much visible axes and spatial axes. Also, these can be divided into three types: 1) Maze Cluster Type, 2) Cross Road Type, and 3) Open Flexible Type. These wall types lead the various changes in circulation, and even each of the arrangement qualities of the exhibitions should be researched according to its exhibition place type.

The Feather Color of chicken is considered as most obvious, and the purpose of this study is to identify the genotype following the SNP of MC1R, MITF and TYRP1, which are genes related to Feather Color, and develop a SNP marker that can be classified per breed. When a haplotype is observed through the combination of markers, a Korean Native Chicken can especially be distinguished when it is a CGG type in the SNP combination of the MC1R gene. In case of the TAG, TGG and TAA types, only Araucana was identified, and for the CAA type, Leghorn could specifically be distinguished. In the SNP combination of TYRP1 gene, only Leghorn was differentiated in case of the TTTCA and CCTCA types, and only Silky Fowl was identified in case of the CTTTA type. The SNP combination of MC1R gene enabled for Korean Native Chicken, Leghorn, and Araucana to be distinguished and each of the SNP and combination of TYRP1 gene allowed for all 4 breeds to be classified. If many researches are conducted about genetic polymorphism between breeds, then it is considered that the differences between breeds will be understood from a molecular biological aspect instead of simply distinguishing the breeds through Feather Color.

The purpose of this study is to investigate the effect of body type(thin, standard, fat), necktie width(narrow, medium, wide), gender(man, woman) on image formation. Sets of stimulus and response scales(7 point semantic) were used as experimental materials. The stimuli were 9 color pictures manipulated with the combination of necktie-width and body type using computer simulation. The subjects were 116 male undergraduates and 99 female undergraduates living in Gyeongsangnam-do. Image factor of the stimulus was composed of 4 different components, young-activity, attractiveness-gracefulness, stability, and boldness. In the young-activity, attractiveness-gracefulness and stability, body type and necktie-width showed independent effect. In the boldness, body type showed independent effect. Significant interaction effects of body type and necktie-width on young-activity, attractiveness-gracefulness and stability were found. For young-activity image, necktie of narrow width were effective. For attractiveness-gracefulness image, body type of standard were effective. For stability image, body type of standard and body type of thin on necktie of narrow and medium width were effective. The male fashion image can be perceived differently according to combination of the clues used in body type and necktie-width. Therefore, when the male fashion to create images that will have to consider the body type and necktie width.

In this study, MBTI(Myers-Briggs Type Indicator) test was carried out targeting flight instructors and student pilots in charge of introductory flight training course. The results was analyzed in accordance with the personality type, the preferred indicator, and the combination of preferred indicators in order to see how these characteristics affect the flight training results. Most of personality types of the instructor, regardless of the attitude category such as E or I, were -STJ(70.6%), however the student pilot showed a variety of personality types, rather than professors. Sensing-type(S) students showed higher academic achievement scores than Intuition-type(N), and Judging-type(J) students showed higher academic achievement scores and pilot qualification scores than Perceiving-type(P). The success rate of Extraversion-type(E) student pilots was higher than that of Introversion-type(I) student pilots. As the personality combinations of instructor and student pilot, the academic achievement scores of Judging-Judging(J-J) type were higher than those of Perceiving-Perceiving(P-P) type. The combination of Extraversion-Extraversion(E-E) type showed higher success rate than Extraversion-Introversion(E-I). This result suggests that if both instructor and student pilot have same attitude of Extroversion(E), good training results can be expected.

The purpose of this article is to present the clinical and laboratory procedures for single tooth restoration using 'Combination Implant Crown'. It is cemented on implant abutment and that abutment is screw-retained over implant body. This type of implant restorations has the advantages of cement-retained restoration while being antirotational and retrievable. And, more esthetic and functional result can be achieved by minimizing the size of access hole. The results were as follows : 1. Preparation of abutment below the cuff line should be avoided 2. Axial reduction of implant abutment should not be excessive because it may weaken the abutment 3. More esthetical and functional occlusal surface was achieved with a minimal access hole which is slightly larger than the diameter of hex driver to enable future total retrievability. 4. Combination Implant Crown has the advantages of both the cement-retained and screw-retained type implant restoration. 5. Cementation between implant crown and abutment reduces screw loosening through even force distribution

PURPOSE. The objective of this literature review was to analyze the cumulative survival rates (CSRs) of rigid and non-rigid double-crown-retained removable dental prostheses. MATERIALS AND METHODS. Screening of the literature published from January 1995 to December 2019 was performed by using electronic data base (Pubmed) and manual search. The CSRs of rigid and non-rigid double crown removable dental prostheses were investigated. RESULTS. A total of 403 articles were reviewed and 56 relevant articles of them were selected. Subsequently, 25 articles were included for data extraction. These articles were classified according to rigid and non-rigid type double crowns and further subdivided into teeth, implants, and teeth-implant combination types. The CSRs of rigid type double crown ranged from 68.9% to 95.1% of 5 to 10 years in tooth abutments, 94.02% to 100% over a 3-year mean observation periods in implant abutments, and 81.8% to 97.6% in tooth-implant combination. Non-rigid type double crowns had various CSR ranges from 34% to 94% maximum during 10 years observation in teeth abutment. The CSRs of non-rigid type had over 98% in implant abutments, and ranged from 85% to 100% in tooth-implant combination. CONCLUSION. The CSRs of double crowns varies according to types. With accurate evaluation of the remaining teeth and plan of the strategic implant placement, it could be successful treatment alternatives for partially or completely edentulous patients.

The purpose of this study is to investigate the effect of hair-style (straight and wave), hair-length(short, medium, and long), and type of hat design (no-hat, beret, cloche, bowler, and capeline) on impression formation. The experimental materials developed for this study were a set of stimulus and response scales. The 7-point semantic differential response scales were designed. Thirty stimuli color pictures of various combination of hair length, hair style, and type of hat design were manipulated by computer drawing. The subjects were 360 undergraduates living in Seoul, Kyunggi and Kyungnam. The experimental design was composed of 3 factorial designs. The result of the study can be summarized as follows; Impression factor of the stimulus consisted of the 5 different dimensions (attractiveness, gracefulness, activity, concentration of attention, cuteness). Hair style greatly affected gracefulness. On the other hand, hair length made remarkable effects on attractiveness, concentration of attention, and cuteness. In addition, it has been found that the type of hat design significantly influenced on all the factors except attractiveness as independent variables. In regarding the effect of interaction between each variable, the combination of hair style and hair length had significant effects on gracefulness. In the impression formation of cuteness, the combination of hair length and type of hat design were more significant.
