Human diphyllobothriasis is a widespread fish-borne zoonosis caused by the infection with broad tapeworms belonging to the genus Diphyllobothrium. In mainland China, so far 20 human cases of Diphyllobothrium infections have been reported, and the etiologic species were identified as D. latum and D. nihonkaiense based on morphological characteristics or molecular analysis. In the present study, proglottids of diphyllobothriid tapeworms from 3 human cases that occurred in Heilongjiang Province, China were identified as D. nihonkaiense by sequencing mitochondrial cytochrome c oxidase subunit I (cox1) and NADH dehydrogenase subunit 5 (nad5) genes. Two different cox1 gene sequences were obtained. One sequence showed 100% homology with those from humans in Japan. The remaining cox1 gene sequence and 2 different nad5 gene sequences obtained were not described previously, and might reflect endemic genetic characterizations. D. nihonkaiense might also be a major causative species of human diphyllobothriasis in China. Meanwhile, the finding of the first pediatric case of D. nihonkaiense infection in China suggests that infants infected with D. nihonkaiense should not be ignored.

A population-based relationship between low vitamin D status and increased cancer risk is now generally accepted. However there were only few studies reported on prognostic impact. To determine the effect of low vitamin D on progression of breast cancer, we conducted a cross-sectional analysis of vitamin D levels and clinico-pathological characteristics in 200 cases of breast cancer diagnosed during 2011-2012 at the National Cancer Institute of Thailand. Vitamin D levels were measured by high-performance liquid chromatography (HPLC). Clinical and pathological data were accessed to examine prognostic effects of vitamin D. We found that the mean vitamin D level was $23.0{\pm}6.61ng/ml$. High vitamin D levels (${\geq}32ng/ml$) were detected in 7% of patients, low levels (<32 ng/ml) in 93% Mean vitamin D levels for stages 1-4 were $26.1{\pm}6.35$, $22.3{\pm}6.34$, $22.2{\pm}6.46$ and $21.3{\pm}5.42ng/ml$ respectively (P=0.016) and 24.1 and 21.3 ng/ml for lymph node negative and positive cases (P=0.006). Low vitamin D level (<32 ng/ml) was significantly found in majority of cases with advanced stage of the disease (P=0.036), positive node involvement (P=0.030) and large tumors (P=0.038). Our findings suggest that low and decreased level of vitamin D might correlate with progression and metastasis of breast cancer.

The development of computer graphics and Internet technology has created a 3D Web-based virtual world that has transformed the global fashion industry environment. In this study, the application cases of 3D virtual fashion education were analyzed to discuss the necessity and application of a 3D apparel CAD curriculum as part of a special education for global fashion talent at Korean fashion-related colleges. Prior studies, literature, photo data and Internet data (in and out of Korea) were used for this study. The demonstration case studies were conducted for the virtual fashion education 'SLCC 2007' of Buffalo State College (U.S.), 'Ratava's Line (2004)' of SFU/FIT Collaborative Design Project (Canada and U.S.) and '2011 Graduation Fashion Show' of Ueda Fashion College (Japan). The results of the study show that the 3D apparel CAD system (as a core technology of the IT fashion industry) would allow the current mass production concept to change to a new paradigm of 'mass customization' along with new fashion business types that include global fashion companies and Web-based Internet, mobile and virtual-world shopping malls. In addition, it appears that the system should be included in the curriculum of fashion-related colleges and institutes to educate technical designers for the global fashion industry and global fashion talent with comprehensive system operation and management ability, and to promote single proprietor companies.

Purpose: Analysis of lower nose and upper lip asymmetry in patients with unilateral cleft lip nose deformity has been proceeded through direct measurement and photo analysis. But there are limitation in presenting real image because of its 2 dimensional trait. The authors analyzed such an asymmetry using 3D VECTRA system (Canfield, NJ, USA) in quantitative way. Methods: In 25 Patients with unilateral cleft lip nose deformity(male 12, female 13, age ranging from 4 to 19), patients with right side deformity were 10 and left were 15. Analysis of asymmetry was proceeded through 3D VECTRA system. After taking 3 dimensional photo, alar area, upper lip area, nostril perimeter, nostril area, Cupid's bow length, nostril height and nostril width were measured. Correlation coefficient and inter data quotients were calculated. Results: In nostril perimeter, maximal difference of cleft side and non - cleft side was 39.3%, asymmetric quotient Qasy = Qcl/Qncl(Qcl, value of cleft side; Qncl, value of non - cleft side) was ranged from 0.84 to 1.85 and in seven cases the length of cleft side was smaller. In nostril area, maximal difference was 69.6% and in 13 cases cleft side was smaller. In lower nasal area, maximal difference was 37.2% asymmetric quotient Qasy = Qcl/Qncl was ranged from 0.47 to 2.03 and in 20 cases cleft side was smaller. The correlation coefficients of nostril perimeter and area were 0.8345. Conclusion: Using 3D VECTRA system, the authors can measure nostril perimeter and lower nasal area that could not been measured with previous methods. Asymmetry of midface was analyzed through area comparison in quantitative way. Futhermore, post operative change can be measured in quantitative method.

In this paper we： (1) analyze the relationship among public R＆D investment, private R＆D investment, and GDP by employing the Clangor causality test; (2) examine if there is any country-specific pattern in the relationship by testing the cases of Korea, the U.S. and Japan. We found some common results for the above countries as follows： (i) GDP causes Public R＆D, not vice versa; (ii) Private R＆D causes GDP; and (iii) Public R＆D does not cause Private R＆D. For the bivariate model of GDP and total R＆D, the results show the existence of one-way causality running from total R＆D to GDP f3r both U.S. and Japan. We also found bidirectional causal relationship between GDP and total R＆D for Korea, which could be interpreted as a typical pattern for newly industrialized countries.

This study analyzed cases that applied hologram technology in the fashion industry in order to provide basic information for research on fashion marketing using hologram technology. The results of this study are as follows. A hologram was applied to fashion businesses in various ways including fashion shows, outdoor signboards, hologram windows or screens in stores, and launching shows or exhibitions. Most of these cases were foreign fashion brands, which utilized hologram technology actively for formulating a new brand image or for advertising products. Among Korean brands, however, there are not many cases of hologram application. Today, as-being the age of smart devices, the mobile advertisement market is growing rapidly among smart phone users. DKNY and Puma are providing information on styling through smart phone applications, and the Adidas stores in Germany also allow the customers to buy goods by entering a simple code through the smart phone. Recently, new devices are being introduced one by one, which display 2D digital contents in 3D holograms by combining mobile and hologram technologies. The marketing of fashion products is not just for supplying products but is required to satisfy the consumers' five senses. Therefore, the development of experiential contents based on the combination of mobile and hologram technologies will open new potential for profitable business models.

The physiological change of eyes while viewing 3D TV was investigated. The change of pupil size was used as the measure of evaluation. The results are as follows: (1) The pupil size decreases after viewing 3D images. (2) The indoor illumination has a significant effect on the pupil size in both 2D and 3D cases. (3) Less change of pupil size were observed under the indoor illumination. Thus, if we only focus on the visual load on the eye, for viewing 3D images, it will be better to use indoor illumination.

The results were as follows. 1. In the incidence of decreased visual acuity, men's was $46.84\%$(37 cases) and women's was $53.16\%$(42 cases), which showed that more women were suffering decreased visual acuity than men. In the incidence of myopic ametropia and astigmatic ametropia among the total patients, men's was $44.62\%$(29 cases) and $37.50\%$(9 cases) each, and women's was $55.38\%$(36 cases) and $62.50\%$( 15 cases) each, which also showed that more women were suffering myopia and astigmatism than men. 2. The average age of patients was 11.08 years at the first visit. The most were the patients from 6 to 15 years old, with 63 cases($79.74\%$). 3. The age of onset in the decreased visual acuity was mainly 6∼10 years with 45 cases($56.96\%$). In the case of myopic ametropia and astigmatic ametropia, the age of onset was also mainly 6∼10 years with 65 cases($60.00\%$), and with 12 cases($50.00\%$) each. 4. In ABO blood type, the frequency was, A type, O type, B type and AB type in order. In men, O type was the most, while in women, A type. 5. In the liking for cool or warm food or tepidity, the liking for cool food was the most in both men and women. 6. The type of decreased visual acuity was mainly myopic ametropia with 65 cases($82.28\%$). Astigmatic ametropia was $30.38\%$ with 24 cases, hyperopic ametropia $2.53\%$ with 4 cases, and the decreased visual acuity accompanied by amblyopia $7.59\%$ with 4 cases. 7. At the first visit, the average visual acuity of O.D. was 0.29 and that of O.S.. 0.24, which showed that O.S.. is worse than O.D.. The visual acuity below 0.2 was the most, $63.29\%\;in\;O.D..\;72.15\%$ in O.S.. 8. In the treatment period, 4∼7 weeks occupied $35.44\%$ with 28 cases, 8∼11 weeks $30.38\%$ with 24 cases, so the treatment period was mainly these two periods with 52 cases($65.82\%$). 9.
