  • Objectives: The purpose of the study is to investigate the related factors to dental care utilization, oral health behaviors, and oral health status in immigrant workers in Korea. Methods: The subjects were 504 foreign immigrant male workers over 20 years old who visited Daegu labor consultation center for oral health survey and oral examination. The questionnaire included 5 questions of socioeconomic characteristics, 8 questions of oral health practice behavior, 6 questions of dental clinic visit, 8 questions of social relations and Korean language proficiency. The question for health behavior was measure by body mass index(BMI). Social relations and Korean language proficiency instrument was modified by Seol from "Family welfare survey in Korean international marriage" and scored by Liker 5 scale. Results: The oral health examination of the immigrant workers was as follows: decayed teeth - 76.6%, filling teeth - 27.4%, missing teeth - 69.8%, dental caries experience above five or more - 60.2%, periodontal pocket tissues - 58.9%. Simplified Oral Hygiene Index was very poor and accounted for 49.0%. Dental care utilization experience was closely associated with social relation indexes including attendance in family events, household stuff help, financial help and counseling for hard work(p<0.01). Dental care utilization experience proportionally increased with proficiency in Korean literacy including speaking, listening, and writing abilities of Korean language(p<0.01). Conclusions: In order to improve the oral health condition of the immigrant workers, it is important to provide social network, Korean language proficiency support, and health insurance coverage through economic burden reduction by the Korean government.

  • There are many theoretical analyses and experimental studies of the hydrodynamics for the tension leg platform (TLP) of a floating wind turbine. However, there has been little research on the arrangement of the TLP's internal structure. In this study, a TLP model and a 5-MW wind turbine model as proposed by the Minstitute of Technology and the National Renewable Energy Laboratory have been adopted, respectively, to comprehensively analyze wind effects and wave and current combinations. The external additional coupling loads on the TLP and the effects of the loads on variables of the internal structure have been calculated. The study investigates preliminary layout parameters-namely, the thickness of the tension leg body, the contact mode of the top tower on the tension leg, the internal stiffening arrangement, and the formation of the spoke structure-and conducts sensitivity analyses of the TLP internal structure. Stress is found to be at a maximum at the top of the tension leg structure and the maximum stress has low sensitivity to the load application point. Different methods of reducing maximum stress have been researched and analyzed, and the effectiveness of these methods is analyzed. Filling of the spoke structure with concrete is discussed. Since the TLP structure for offshore wind power is still under early exploration, arrangements and the configuration of the internal structure, exploration and improvements are ongoing. With regard to its research and analysis process, this paper aims to guide future applications of tension leg structures for floating wind turbine.

  • In recent years, intense cold spells caused by climate change have encouraged an increasing number of people to wear a variety of padded jackets. In this context, this paper aims to address the production of padded jackets in casual brands and to develop basic patterns for well-fitted padded jackets targeted toward women in their 20s. The study centered on the production of padded jackets from 13 apparel companies. In addition, three sample jackets were created with 3oz. fill in the body and 2oz. fill in the sleeves, and they were subjected to a wearing test to determine their movement functionality. The research findings were as follows. Woven jackets constituted 53.4% of the winter jackets produced by casual brands; padded jackets accounted for 25.3%, leather jackets 12.6%, and other jackets 8.7%. Thus, data showed that padded jackets accounted for a considerable proportion of overall winter jacket production. Based on the wearing test results, the basic measurements of a padded jacket for women in their 20s were as follows: bust girth of B/4+3cm front length and B/4+3.5cm back length; waist girth of W/4+3.1 cm front length and W/4+1.9cm back length; and hip girth of H/4+3.3cm front length and H/4+2.8cm back length. The jacket length was set at 62.8cm, with a 63.8cm sleeve length. This study concluded that providing padded jacket manufacturers with basic pattern designs for a well-fitted jacket is expected to boost the efficiency of pattern design processes and the production of padded jackets.

  • A 2-year-old male, 3 kg body weight Japanese Chin was injured in the automobile accident three months ago. The dog became antebrachiocarpal joint instability, and performed pancarpal arthrodesis using 3 K-wires in localanimal hospital. But, the result was failure. Therefore the dog was referred to Chonbuk Animal Medical Center, Chonbuk National University. In physical examination, right carpal joint instability, knuckling sign and pain were evident. In radiography, sclerosis was observed on the 4th carpal bone. Complete blood count (CBC), serum chemistry and urinalysis finding were within reference ranges. Pancarpal arthrodesis was re-performed using 7-hole plate. However, mild skin and muscle defects was appeared by skin tension of extremity. We expected that granulation would fill the defect, but inflammation was continued on the lesions for 3 days. So, operation which is filling it was done by using the muscle flap and tubed skin flap. The donor muscles were flexor carpi radialis and superficial digital flexor muscles. After 7 days, the muscle flap was survived, but tubed skin flap was necrosed. After 20 days, the skin defect was substituted with granulation tissues. The flexor carpi radialis muscle and superficial digital flexor muscle transposition can be a useful procedure for reconstructing soft tissue defects in the carpal and metacarpal areas.

  • Molding of body with ribs is the most difficult during flow molding process. The rib area is easy to be deformed at the rear side due to wall thickness variation. In this study, relationships between molding condition and deflection of rib-shaped part is investigated during the compression molding of fiber reinforced plastic composites, and the following results are derived. Polypropylene(PP), Polystyrene(PS), and stampable sheet(SS 40wt%) show the increment of deflection along with releasing temperature. For the correlation between incremental holding pressure load and deflection, stampable sheet exhibits lower deflection along with higher holding pressure, while PS shows significant increase of deflection with higher holding pressure, PP shows completely different characteristic, significant reduction of deflection along with higher holding pressure. Regarding to mold temperature and deflection, deflection amount of SS is the biggest, and PS shows the smallest. In addition, all three kinds shows the highest amount of deflection at 173C. Deflection is reduced when mold closing speed is increased. Amount of deflection in SS is larger and is not highly dependent on molding conditions like holding pressure and cooling parameters, compared with single component material like PP. This can be elucidated by anisotropic and inhomogeneous characteristics of glass fiber during filling process of stampable sheet composite.

  • Captured specimens of the lesser white-toothed shrew, Crocidura suaveolens were classified into three age classes by tooth wear and seasonal variations of reproductive organs were investigated. Molars of juveniles had not tooth wear and the height of the third molars were lower than the first and second molars, young adults had smooth tooth wear and the third molars reached to the first and second molars, and old adults had heavy tooth wear and the third molars also reached to the first and second molars. On the basis of histological examination, seasonal variation of breeding was confirmed that breeding season of adult males was from early February to early October, having a peak of the breeding in April and July, and non-breeding season was from in the middle of October to late January. Young and old adult males of the breeding season had large testes with enlarged seminiferous tubules filling with numerous germ cells and expanded caudal epididymides with a vast number of spermatozoa, Young and old adult males of the non-breeding season had the small testes with the extremely slender seminiferous tubules filling with only spermatogonia and the reduced caudal epididymides without spermatozoa. Males weighing more than 3.9 g in the body weight and 0.013 g in the testis and epididymis weight reached sexual maturation in breeding season, and the females weighing more than 3.8 g in body weight of the breeding season were pregnant condition having 5~6 litters or had the Graafian follicles and the corpus lutea in the ovary.

  • Mycelial growth and fruit body formation of Diehlomyces microsporus were best on mushroom spawn extract medium and rice bran extract medium, respectively. L-asparagine, fructose and glucose were good nutrient sources for mycelial growth. Optimum temperature for mycelial growth ranged at $25{\sim}28^{\circ}C$. Maximum mycelial growth occurred at pH 5.5 while optimum pH for ascospore germination was 6.0. Mycelial mats of D. microsporus did not survive at $60^{\circ}C$ for 60 minutes while ascospores at $80^{\circ}C$ for 120 minutes. Damages of fruit body of Agaricus bisporus caused by D. microsporus were maximum when the fruit bodies were infected at spawning and casing on the compost. The truffle disease could be controlled by basamid with $100{\sim}150 ppm$ treating on the compost after filling.

  • The purpose of this study is to analyze four separate elements-sublime beauty, elegant beauty, mysticism, ornament-which appeared in materials, patterns, colors, silhouettes, details, and accessories, laying stress on luxurious, brilliant, mysterious feelings on Gorgeous Images appeared as trend theme of modern fashion by mixing religious mysticism of the Byzantine Empire. Mysticism element is using the effect of splendid and gorgeous colors from the Orient rather than forms. And a philosophy of abundant colors in mosaics, which are seen in art forms such as architecture, paintings, etc., shows that it creates some visual rooms for religious spirits. Influenced by the fashion of the Greco-Roman style, the elegant beauty element is expressing abundant comfort and elegant feminine lines that are from creases, and it is also emphasizing natural beauty which seems to slip down by displaying the splendid images of Gorgeous as drapes that fit a body. Ornament element was reflecting an inspiration from the splendid and brilliant culture of religion in the Byzantine Age. Therefore, it was appeared as a style filling the whole with bulky silks, splendid ornamental materials embroidered in gold or silver thread, the complicated geometric patterns that are two-dimensional and dignified, and so on. It was decorated with crosses which represent Christianity as a motif, and also it emphasized the splendor of the Byzantine and dazzling splendid images of Gorgeous by using accessaries decorated with various jewels. The elements of sublime beauty are showing the beauty adding humble and majestic images to it as designs sought by spiritual values or intrinsic values. Those designs, so to speak, have pretense which does not allow to expose a body and plain pure feeling, so that they are showing some abstinent styles in a solemn atmosphere, with most details removed. We can say the Fashion Theme appearing in Modern Times is the result from representing by combining various factors of the times with formative beauty through creative works for aesthetic expression. The moderners are requiring new designs which is possible to meet their individualities, in addition to their outstanding fashion senses. From this point of view, a variety of textiles, patterns, and colors in the Byzantine have a great meaning to fulfill people's various desires as interesting elements.

  • Through the photometric observations of the near-contact binary, XZ CMi, new BV light curves were secured and seven times of minimum light were determined. An intensive period study with all published timings, including ours, confirms that the period of XZ CMi has varied in a cyclic period variation superposed on a secular period decrease over last 70 years. Assuming the cyclic change of period to occur by a light-time effect due to a third-body, the light-time orbit with a semi-amplitude of 0.0056d, a period of 29y and an eccentricity of 0.71 was calculated. The observed secular period decrease of $-5.26{\times}10^{-11}d/P$ was interpreted as a result of simultaneous occurrence of both a period decrease of $-8.20{\times}10^{-11}d/P$ by angular momentum loss (AML) due to a magnetic braking stellar wind and a period increase of $2.94{\times}10^{-11}d/P$ by a mass transfer from the less massive secondary to the primary components in the system. In this line the decreasing rate of period due to AML is about 3 times larger than the increasing one by a mass transfer in their absolute values. The latter implies a mass transfer of $\dot{M}_s=3.21{\times}10^{-8}M_{\odot}y^{-1}$ from the less massive secondary to the primary. The BV light curves with the latest Wilson-Devinney binary code were analyzed for two separate models of 8200K and 7000K as the photospheric temperature of the primary component. Both models confirm that XZ CMi is truly a near-contact binary with a less massive secondary completely filling Roche lobe and a primary inside the inner Roche lobe and there is a third-light corresponding to about 15-17% of the total system light. However, the third-light source can not be the same as the third-body suggested from the period study. At the present, however, we can not determine which one between two models is better fitted to the observations because of a negligible difference of $\sum(O-C)^2$ between them. The diversity of mass ratios, with which previous investigators were in disagreement, still remains to be one of unsolved problems in XZ CMi system. Spectroscopic observations for a radial velocity curve and high-resolution spectra as well as a high-precision photometry are needed to resolve some of remaining problems.
