  • This study was initiated to observe the growth of the lengths of the body, the antenna, the rostrum, the fore leg, the middle leg, the hind leg and the width of pronotum in the postembryonic development of Anoplocnemis dallasi. The specimens measured were fifty in the first instar larva and seventy for each instar from the second instar larva to adult stage. The authors applied the growth formula and the relative growth formula to analyse the changing pattern of the growth of each part. In this paper, having applied the formulae the y=a+bt+$ct^2$ for the absolute growth and $y=bx^{\alpha}$ for the relative growth, we obtained the following results: $\circled1$ The growth quantity: The rostrum shows the slowest, straight increase, but the other shows the curving increase. The body, the hind leg, the middle leg, the fore leg, the antenna, the width of pronotum and the rostrum are systematically slow. $\circled2$ The ratio of the growth quantity: The increase rate of the rostrum shows the straight, while the other shows the curving patterns. The largest value is the increase rate of the width of pronotum (8.816 times) and the smallest one is the rostrum (3.054 times). $\circled3$ The growth ratio for each instar: The maximal ratio of the growth quantity is in the young instar larva, but the minimal one is in an advanced instar larva. $\circled4$ The growth rate: The antenna shows a decrease pattern, while the other an increase pattern. $\circled5$ The specific growth rate: The rates of the antenna, the for leg, the rostrum, the hind leg and the middle leg show a decrease pattern. In the width of pronotum and the body, they increase in the terms of the young instar larva and they increase later. The antenna shows the most rapid decrease, and the fore leg, the rostrum, the hind and the middle leg are slow in order. $\circled6$ The "$\alpha$" of the width of pronotum shows the strongest positive allometry, but the rostrum shows the weakest negative allometry to all parts. $\circled7$ The coefficient of the relative growth of each part shows a parallel fashion in the relative growth to body length, to width of pronotum, to antenna, to rostrum, to fore leg, to middle leg and to hind leg. $\circled8$ If the coefficient of the relative growth, the growth ratio ($\alpha$) increase, the initial growth index (b) is disposed to decrease and vice versa. $\circled9$ The growth center is in the terms of the young instar larva in case of the negative allometry, but it is in the terms of an advanced instar larva in case of the positive allometry.

  • Recently, young men have become more muscular, as they have become increasingly more interested in health and their physical appearances. The trend these days is to wear slim suits to accentuate their figures. Men's pants are the one of the most general clothes which men wears. While pants are an ordinary item of clothing, most muscular men have fitting problems with ready-made pants. In view of this, this study aimed at developing a prototype pants pattern for muscular men. In this study, five muscular men were selected for wearing tests. The regression formulas, in which muscular men's body measurements were adopted, were applied to unsuitable body parts, especially the body parts determined inappropriate based on the results of the existing pants pattern wearing tests. After going through the first and second pants pattern wearing tests, the final pants patterns were developed that were suitable for muscular men. The results of the study were as follows: In order to solve the problem of the insufficient of ease due to the development of the hip muscles, the crotch length was made longer, (0.08${\times}$hip circumference+17.648)+1.5cm and front crotch width and back crotch width were made wider, 1.0cm each than those of the existing pants prototype patterns. The ease of 0.5cm was added to the hip circumference/4+2.5cm because of the development of the hip and thigh muscles.

  • This study was intended to analyze conventional grading increments and methods for middle-age men's pants, and to suggest new grading guidelines that will enable to improve satisfaction with size and silhouette as a result of combining the concept of grading, which help maintain the ratio and proportion by sizes as one of ready-made apparel's advantages, with body form oriented and aesthetic approaches. In the apparel industry, the current sizing specifications and methods adopted by relevant companies, as well as the characteristics of body forms of men aged 35 to 55 years were comparatively analyzed to find out problems and ultimately to suggest their solutions or improvements. It was considered that as the conventional grading practices used in the industry were customary on the basis of the past experiences, it was required to take the body forms of target consumers into account and also, to reconsider the conventional grading methods. Analyses of sizing and specifications by brands show that 4 to 19 sizes including 82 or 84 as standard size have been produced. Since men's apparel has a large number of sizes with the large range of sizes, grading is critically important. As silhouettes depend on the distribution of grading rule values at each point of increment pattern in the main regions during grading, it is necessary to consider both size grading and form variations. To maintain an appropriate silhouette with keeping the angle of center back line of a pattern, it is desirable to set the ratio of side line part to center part from the crease line to approximately 3:7. It is required to diversify the values of grading rules according to different sizes and pattern regions in consideration for the body forms of key consumers. In addition, if the natural lines of designs and patterns for the width increments of waist circumference and hip circumference, the increments of hip width in pant's front and back panels, the ratio of grading rule values of the right and left sides of crease line, knee circumference, thigh circumference and so on are taken into account, grading will be satisfactory in the all aspects of size, silhouette and ratio.

  • This study attempted to find out the difference in the patterns of jeogori between commercially available Shinhanbok brands by comparing and analyzing the patterns of the changing Shinhanbok jeogori in consideration of material characteristics, fit, and fastening. After purchasing and disassembling 6 products, analysis was conducted with the disassembly pattern. As a result of analyzing the shape of the jeogori, the 1st, 3rd and 6th brands showed no darts. In the case of the 5th brand, the three-dimensional effect of the human body was expressed with a princess line. As a result of the appearance evaluation, the 5 brands were evaluated as the highest in most items except for the space of the front width and the group wrinkles of back sleeve armhole, and the appearance was analyzed to be the best. As a result of evaluating the clothing pressure, it was analyzed that the chest circumference of the first brand was smaller than that of the other brands, and the shoulder width and shoulder length were also shorter, and pulling occurred even after wearing. As the demand for new hanbok increases, it is believed that it is necessary to establish a size system for ready-made clothes.

  • The purpose of this study is to suggest a theoretical basis to name Sa(紗) and Ra(羅) remains properly by comparing and analyzing the name, usage, value, length and width of Sa(紗) and Ra(羅) recorded on documents made at the end period of Joseon. The features of Sa(紗) and Ra(羅) at the end of the Joseon Period are as follows. 1. The kinds of Sa(紗) are about 80, those of Ra(羅) are about 12, and those of Sa(紗) are significantly more than those of Ra(羅). In regard to the aspect of patterns, there were about 20 types of patterns in the case of Sa(紗), but no specific pattern for Ra(羅). 2. Some newly revealed patterns in the case of Sa (紗) are as follows. Baek -bok-mun(백복문) was a pattern full of ‘bats(박쥐[복])’, and Baek-jeop-mun(백접문) was a pattern full of ‘butterflies(나비[蝶])’ Jeop-mun(접문) was classified into ‘butterfly patterns(나비문[접문])’ and ‘traditional window flame patterns(창살문[접문])‘. 3. When considering the usages of Sa(紗) and Ra(羅), Sa(紗) was used for various detailed purposes according to their kinds and patterns, but Ra(羅) was mostly used for underwear. The most commonly used Sa(紗) was the Gab-sa type(甲紗類). On the contrary, the Go-sa type(庫紗類) was significantly less used than the Gab-sa type(甲紗類). However, it must have been of relatively high quality Sa(紗), shown by the fact that it was used for outer garments. In addition, the Gung-sa type(宮紗類) was the best quality Sa(紗), shown by the fact that it was used for court dress and official uniforms in the royal court. 4. Sa(紗) and Ra(羅) whose features have been examined we Gapsa(甲紗), Sun-in (純仁), Gosa(庫紗), Gwansa(官紗), Jusa(走紗), Eunjosa(은조사), Gwangsa(廣紗), Waesa(倭紗), Dorisa(도리사), Gong-yangsa(공양사), Rasa(羅紗), Danghangra(唐亢羅), Yanghangra(洋亢羅), Yunjura(윤주라), Eunra(銀羅), Jeohangra(저항라), Chura(秋羅). 5. Regarding the values of Sa(紗) and Ra(羅), they were high quality textures and its length and width of 1 Pil(疋), a roll of cloth, were not subdivided in detail such as in the case of plain weaved silks(平絹).

  • Background It is still difficult to prevent partial or full-thickness flap necrosis. In this study, the effects of a cream containing menthol and methyl salicylate on the viability of random-pattern skin flaps were studied. Methods Forty female Sprague-Dawley rats were divided into two equal groups. Caudally based dorsal random-pattern skin flaps were elevated, including the panniculus carnosus. In the study group, 1.5 mL of a cream containing menthol and methyl salicylate was applied to the skin of the flap, and saline solution (0.9%) was used in the control group. Upon completion of the experiment, flap necrosis was analyzed with imaging software and radionuclide scintigraphy. Histopathological measurements were made of the percentage of viable flaps, the number of vessels, and the width of the panniculus carnosus muscle. Results According to the photographic analysis, the mean viable flap surface area in the study group was larger than that in the control group (P=0.004). According to the scintigrams, no change in radioactivity uptake was seen in the study group (P>0.05). However, a significant decrease was observed in the control group (P=0.006). No statistically significant differences were observed between the groups in terms of the percentage of viable flaps, the number of vessels, or the width of the panniculus carnosus muscle (P>0.05). Conclusions Based on these results, it is certain that the cream did not reduce the viability of the flaps. Due to its vasodilatory effect, it can be used as a component of the dressing in reconstructive operations where skin perfusion is compromised.

  • Purpose: This study evaluated and compared interradicular distances and cortical bone thickness in Thai patients with Class I and Class II skeletal patterns, using cone-beam computed tomography (CBCT). Materials and Methods: Pretreatment CBCT images of 24 Thai orthodontic patients with Class I and Class II skeletal patterns were included in the study. Three measurements were chosen for investigation: the mesiodistal distance between the roots, the width of the buccolingual alveolar process, and buccal cortical bone thickness. All distances were recorded at five different levels from the cementoenamel junction (CEJ). Descriptive statistical analysis and t-tests were performed, with the significance level for all tests set at p<0.05. Results: Patients with a Class II skeletal pattern showed significantly greater maxillary mesiodistal distances (between the first and second premolars) and widths of the buccolingual alveolar process (between the first and second molars) than Class I skeletal pattern patients at 10 mm above the CEJ. The maxillary buccal cortical bone thicknesses between the second premolar and first molar at 8 mm above the CEJ in Class II patients were likewise significantly greater than in Class I patients. Patients with a Class I skeletal pattern showed significantly wider mandibular buccolingual alveolar processes than did Class II patients (between the first and second molars) at 4, 6, and 8 mm below the CEJ. Conclusion: In both the maxilla and mandible, the mesiodistal distances, the width of the buccolingual alveolar process, and buccal cortical bone thickness tended to increase from the CEJ to the apex in both Class I and Class II skeletal patterns.

  • An H-sector horn antenna has a constant beam coverage characteristic and it can be useful for application to a wide band phased array antenna system. In this paper, we designed a broadband E-plane H-sector horn phased-array antenna, which has a 3:1 bandwidth and ${\pm}60^{\circ}$ beam steering capability. An H-sector hem antenna was designed to have $30{\sim}50^{\circ}$ half-power beam width in the principal H-plane. The active reflection coefficient including mutual coupling was calculated using a waveguide simulator, and the active reflection characteristic was improved by mutual coupling over wide frequency range. Using these results, an $8{\times}1$ H-sector phased array antenna was fabricated. The measurement results for the half-power beam width in the principal H-plane and the active reflection coefficient showed a good agreement with the simulation results. The peak-value pattern in the steered radiation beams also agreed well with the active element pattern. The measured active reflection coefficients within the beam steering range are mostly less than 0.3 over the 3:1 frequency range.
