Purpose: The purpose of this study was to investigate the effects of implant collar design on marginal bone change and soft tissue response by an animal test. Materials and methods: Two types of Implant (Neobiotech Co. Seoul, Korea) that only differs in collar design were planted on two healthy Beagle dogs. The implants were divided into two groups, the first group with a beveled collar (Bevel Group) and the second group with "S" shaped collar (Bioseal group). Standardized intraoral radiographs were used to investigate the mesio-distal change of the marginal bone. Histological analysis was done to evaluate the bucco-lingual marginal bone resorption and the soft tissue response adjacent to the implant. Mann-Whitney test was done to compare the mesio-distal marginal bone change at equivalent time for taking the radiographs and the tissue measurements between the groups. Results: Radiographic and histological analysis showed that there was no difference in marginal bone change between the two groups (P>.05). Histological analysis showed Bioseal group had more rigid connective tissue attachment than the Bevel group. There was no difference in biological width (P>.05). Bevel group showed significantly longer junctional epithelium attachment and Bioseal group showed longer connective tissue attachment (P<.05). Conclusion: For three months there were no differences in marginal bone change between the Bevel group and the Bioseal group. As for the soft tissue adjacent to the implant, Bioseal group showed longer connective tissue attachment while showing shorter junctional epithelium attachment. There were no differences in biologic width.

The purpose of this study is to fundamentally examine the vests of the robes "Daeraebok" and "Soraebok" of the Korean Empire from the 1876 Port Opening to the 1910 annexation of Korea to Japan. Among the collections of different robes of the Korean Empire which belong to various universities and institutions, only the vests were surveyed. The shape of the vests in the Korean Empire were single-breasted and double-breasted. Most V-necklines and vests with a shawl collar look like a tailored collar, where the collar outline was shaped like a notched and picked collar, which is a mix of the step collar and roll collar of the 19th century. The rear center line was not flat, but inclined to a triangle. All vests of the robe Daeraebok were equipped with gold buttons, and those of the robe Soraebok had black satin buttons. The tailoring characteristic is that the front has a different material (dark black wool) from the back (black silk). This characteristic is expected to be an important basic piece of information in the restoration and reproduction of the vest, which was worn during the imperial period, especially to reveal its shape, characteristics and composition. This characteristic can also be used as data of cultural contents based on Korean modern history.

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.

This research was conducted to understand the different circumstances for wearing shirts by adult males aged 20-39, and to provide this basic information to the shirt industry prior to developing new functional men's shirts. A total of 345 respondents participated in the survey. Most of questionnaire, frequency, mean and standard deviation were calculated and the differences between the 20s and 30s were analyzed by t-test or ${\chi}^2$ test. The results of the survey are as follows. Grading the satisfaction degree of their body parts, the respondents were relatively unsatisfied with their height, weight, and waist, abdominal and hip circumferences. Majority preferred department stores, discount stores and outlets for purchasing shirts. Many have never owned tailored shirts - men in 20's had less experience with tailoring than men in 30's. The foremost selection criterion for purchasing shirts was fit -during purchase, men in their 20's considered fit more important than men in their 30's. The most preferred unbuttoning of the top button when wearing shirts. For favored collar shapes with one button unbuttoned, the most valued collar angle and style was V-neck shape when unbuttoned, low collar band, collar with unopened collar, and stiff collars. Most shirt designs and details included slim fit, no dart in the front and one dart on the back. Men in 20's more preferred the no dart in the front and one tuck on the back, as compared to men in 30's. On the other hand, men in their 30's preferred one dart shirts than men in 20's. Regarding shirt bands and cuffs, one button and regular collar and one button cuffs with round angle design, were the most preferred, respectively.

Jackets are regarded as an element used to judge ideas and fashion trends for the age in which they are presented. This article analyzed recent tailored jacket fashion trends by categorizing jackets according to design elements. For this, design elements of tailored jackets were categorized into silhouette, collar and lapel, shoulder and sleeve, and decorative elements. We collected and categorized the changes of 491 jackets that have appeared in collections over the past 5 years. The results showed shoulder and sleeve changes (36.25%), silhouette changes (33.4%), lapel and color changes (12.6%), decorative element changes (11.2%), and no changes (6.5%). Jacket forms with changed shoulders and sleeves appeared as styles that have laterally or vertically expanded the shoulder and arm hole with the production of various sleeve forms. Silhouette changes were expressed through forms such as exaggerated silhouettes of oversized-clothing, silhouettes made through cutting or layering, and the polarization of length. Forms with a changed collar and lapel appeared with polarization trends in which lapels dramatically grow larger or narrower, diverse frontal adjustments using no-collar designs, and the utilization of shawl-collars; in addition, forms with changed decorative elements were expressed with layered decorations such as pockets or collar add-ons, adjustment changes using buttons, ribbons or zippers, and various trimmings. The analysis results show that modern female tailored jackets are being made to realize an exaggerated physical beauty of shoulder, sleeve and torsos to maximize decorative effects through new attempts in design.

This study intends to provide sources which enable students to satisfy uniform design as I surveyed preferable uniform design and degree of satisfaction of uniform design to students. The subjects were gathered into 91 middle-high schools and surveys were done among 400 school girls. The results are as follows; 1)The survey of uniform which students wear. For jacket, tailored collar which is single breasted is most common and for blouse, puff sleeve, soutein collar, shirt collar is common. For skirt, lastly, they usually wear side pleats skirt. 2) Thoughts of uniform students preferred uniform to casual. The merit of wearing uniform can represent themselves as the ‘students’on the other hand, the demerit is shown that uniform is inconvenient enough to move. 3)Preference of uniform design. Students prefer tailored jacket, shirt blouse, flare skirt. Basing on these results above, I’d like to suggest something about uniform. The demerit of wearing uniform lies in inconvenience. It would weaken the degree of satisfaction of uniform and have a negative influence on students in physical and mental side. So we have to find out the concrete problems, at the same time, develop measurable study which fit for body. Adolescence is period of developing and establishing self. So they really need rather creative educational atmosphere than stereo typed-control. Reflecting this opinion, Clothing habits can play an important role and in future it is desirable to have students wear not uniform but casual.

Investigation was carried out on response of Tetrapleura tetraptera (Schum. and Thonn.) to soil, water and light with the view of its domestication and introduction to different ecological regions. The experiment was arranged in a factorial experiment of $3{\times}3{\times}3$ in a completely randomized design (CRD) with three replicates. The factors were: soil textural class (Loamy sand, Sand and Sandy clay loam), watering regime (daily, twice a week and once a week) and light intensity (100%, 75% and 50%). Soil textural classes had significant influence on collar diameter, stem height, number of leaflets, root/shoot ratio and relative growth rate of Tetrapleura seedlings. Seedlings grown on loamy sand recorded the highest mean value- 2.28 mm for collar diameter, stem height- 12.9 cm, number of leaflets- 19.9, chlorophyll b- $0.34mg\;mL^{-1}$, leaf relative water content- 27.4% and relative growth rate- $0.037mg\;g^{-1}\;day^{-1}$. Watering regime had significant influence on the collar diameter of Tetrapleura. Seedlings watered daily recorded the highest mean value- 2.25 mm for collar diameter. Light intensity significantly influenced collar diameter and root/shoot ratio. Seedlings exposed to 100% light intensity recorded higher mean value for collar diameter- 2.28 mm and root/shoot ratio- 1.481 cm. The interaction between soil textural class and light intensity significantly affected collar diameter, stem height and number of leaflets. Higher mean value for collar diameter (2.47 mm) stem height (13.25 cm) and number of leaflets (21.16) were recorded while the interaction between soil textural class, light intensity and watering regime was significant for only number of leaflets. Tetrapleura exhibited some level of tolerance to different soil texture, drought and light intensity. Therefore, Tetrapleura has the potentials to be raised in different ecological zones characterized by difference in soil, rainfall and amount of sunshine.

This study is about reproduction of Yoseon-Cheobli excavated from Byun-su tomb in earlier Joseon Dynasty. There are three Yoseon-Cheobli in Byun-su tomb. The producing process is made in concrete by suggesting the process of producing clothing. Based on the Annals of the Joseon Dynasty, the most frequently recorded one, was reproduced by dying fabric with safflower and indigo plants. Through the research about their specific size, sewing method and construction, it have been produced in the following. First, the revealing that collar to be half-square and to compose the line in the center of collar. The width of the collar is 11.6 12.1cm. Second, the 21~22 pairs of waist lines that are 13~14cm in width fixed at intervals of 0.3cm. The method of making waist lines is twisting either fabrics or silk threads. Third, fine gathering around the part of the waist of skirt, and the size of fold surface is 0.2cm. Sewing method needs running stitch and backstitch. As the result of producing the cloth, it became to possess more ornamental features after transformation suitable to the new environment while the same remained functional features for everyday life such as a dressing shape, length of the bodice and curvy completion line of a collar strip.

A major mechanical problem with total hip replacement is the loosening of the femoral component. The loss of proximal support, with firm fixation distally, has been thought to be a major caused of fatigue failure of femoral stems. While many causes have been proposed, the most frequently suggested cause of the calcar resorption is the disuse atrophy of the cortex of the calcar due to the stress shielding of the proximal bone by the metal femoral stem. In this research, the new-designed stem(modified collar stem) was considered which made a hole inside stem and had a 3 mm thickness. Using the 3-dimensional finite element methods, the common collar stem and the modified colla stem was modeled and analysed. Also, the two models was compared. The results showed that the modified collar stem decreased the stress-shielding and it made a effective load transfer at the entire femoral region.

Statement of problem: Peri-implant marginal bone loss is an important factor that affects the success of implants in esthetics and function. Various efforts have been made to reduce this bone loss by improving implant design and surface texture. Previous studies have shown that early marginal bone loss is affected by implant neck designs. Purpose: The purpose of this study was to examine the influence of laser microtexturing of implant collar on peri-implant marginal bone loss. Materials and methods: Radiographical marginal bone loss was examined in patients treated with implant-supported fixed partial dentures. Marginal bone level was examined with 101 implant fixtures installed in 53 patients at three periods(at the time of implantation, prosthetic treatment and 6-month after loading). Four types of implants were examined. The differences of bone loss between implants(ITI standard) with enough biologic width and implants(ITI esthetic plus, Silhouette IC, Silhouette IC Laser-$Lok^{TM}$) with insufficient biologic width have been compared. Resorption angles were examined at the time of prosthetic delivery and 6-month after loading. Results and Conclusion: Within the limitation of this study, the following results were drawn. 1. The marginal bone loss of ITI standard and Silhouette IC Laser-$Lok^{TM}$ was less than that of ITI esthetic plus and Silhouette IC(P<0.05). The marginal bone loss between ITI standard and Silhouette IC Laser-$Lok^{TM}$ had no significant statistical difference(P>0.05). There was no significant statistical difference between marginal bone loss of ITI esthetic plus and Silhouette IC(P>0.05). 2. There was no significant difference in marginal bone loss between maxilla and mandible(P>0.05). 3. There was no significant difference in resorption angle among four types of implants(P>0.05). The marginal bone of implants with supracrestal collar design of less than that of biologic width had resorbed more than those with sufficient collar length. The roughness and laser microtexturing of implant neck seem to affect these results. If an implant with collar length of biologic width, exposure of fixture is a possible complication especially in the anterior regions of dentition that demand high esthetics. Short smooth neck implant are often recommended in these areas which may lack the distance between microgap and the marginal bone level. In these cases, the preservation of marginal bone must be put into consideration. From the result of this study, it may be concluded that laser microtexturing of implant neck is helpful in the preservation of marginal bone.
