As the used trading market grows centered on online platforms, it is evolving from practical consumption to pursuing various forms of consumption value. Consumers purchase rare products, enjoy the transaction itself with consumers with the same preference, and investment or eco-friendly value consumption is also increasing. In this regard, the transaction of the second-hand transaction app service must have sincerity in order to respond to various consumption values. In addition, it is necessary to study what components the second-hand trading app service should aim for to secure authenticity and how the usefulness and ease of second-hand trading apps affect the relationship. The research used a questionnaire method to test hypotheses and surveyed 215 consumers in their 20s, 30s, and 40s who had purchased used clothing online within a year. Among them, 200 responses, excluding outliers, were statistically analyzed using SPSS 21.0 and AMOS 22.0 as confirmatory factor analysis and structural equation models. This study aims to determine the effect of the authenticity of the online used trading app service on the satisfaction of the used trading app service. To this end, based on the previous research results, the following research hypotheses were established and verified statistically. First, the authenticity of the online used trading app service will significantly impact the satisfaction of the used trading app service. Second, the usefulness of the used trading app service will have a moderating effect on the effect of the authenticity of the used trading app service on the satisfaction of the used trading app service. Third, the ease of the used trading app service will have a moderating effect on the authenticity of the used trading app service on the satisfaction of the used trading app service. As a result of the study, the authenticity of the used trading app service significantly affected the satisfaction of the used trading app service. Appeared to be The results of this study will help understand used transaction app services where consumption of used products occurs from the viewpoint of product circular use behavior and can be used as a strategic plan to promote the use of used transaction apps in the future.

Emergy concept was used to evaluate the contributions of a dam construction to the real wealth of our economy. A dam that is proposed as a multi-purpose dam was used to illustrate emergy evaluation methodology. Models for emergy evaluation were constructed with energy systems language, a symbolic modeling language which presents network properties of systems holistically. Water supply was the most important contribution in terms of emergy, which reflects that the dam is proposed for stable water supply to a local region. Generation of electricity was the second in emergy benefits of the dam. Emergy costs were more evenly distributed among the costs which would occur as a result of the dam construction. Emergy yield ratio was 1.30 if sediments are not included, and 1.15 if sediments are included, which results in net yield in both cases. The ratio would, however, fall below 1.0 if rare species within the system boundary are lost as a result of the dam construction because of the high emergy value included in biotic species, which means that emergy costs will be greater than emergy benefits. This study illustrated a new methodology in environmental impact assessment to better manage our environments in an age of diminishing resources.

Enormous interest in trivalent rare-earth (RE) ions activated luminescent materials has been gaining owing to their promising applications in bio-imaging, solar cells, white light-emitting diodes and field-emission displays. Among these trivalent RE ions, dysprosium (Dy3+) was widely investigated due to its unique photoluminescence (PL) emissions. A series of Dy3+-activated CaWO4 phosphors were prepared by a facile high-temperature solid-state reaction method. The X-ray diffraction, PL spectra, cathodoluminescence (CL) spectra as well as PL decay curves were used to characterize the prepared samples. Under ultraviolet light excitation, the characteristic emissions of Dy3+ ions were observed in all the obtained phosphors. Furthermore, the PL emission intensity increased gradually with the increment of Dy3+ ion concentration, reaching its maximum value at an optimized Dy3+ ion concentration. Additionally, color-tunable emissions were obtained in Dy3+-activated CaWO4 system by adjusting the Dy3+ ion concentration and excitation wavelength. Ultimately, strong CL properties were observed in Dy3+-activted CaWO4 phosphors. These results suggested that the Dy3+-activted CaWO4 phosphors may have potential applications in the field of miniature color displays.

Germanium is found in a range of minerals and ores and is present in foods including beans, tomato juice, oysters, tuna and garlic. Germanium is a non-metallic element, which can exist in valence states of 2 and 4. Clinical trials and use in private practices for more than a decade have demonstrated organic germanium's efficacy in treating serious disease including cancer, arthritis and senile osteoporosis. But it was rarely reported that inorganic germanium has biological properties. STB-BM contains mineral complex, rare earth elements and a little amount of Inorganic germanium. The experiment was carried out the anti-obesity effect. To investigate anti-obesity effect of STB-BM, we measured the effect of body weight, fat weight (subcutaneous fat, epididymal fat, visceral fat, kidney fat and total fat) and serum biochemical level in rats fed high fat diets. STB-BM 35 mg/kg suppressed the increasing ratio of body weight, epididymal fat weight, visceral fat weight, total fat weight, triglyceride and LDL-cholesterol (p<0.05).

Art deco means decorative form on the base of cubism which has widely spread from 1910's to 1930's. Also it pursued the rational & functional design even than deecoration of art nouvear, and colorful combination of fauvism. The analytical study on design included occurrence, developing process and formative features expressed in the art deco fashion. The changes of the art deco style, it referred to the fashion illustration which was the Graphic-s of Ert in 19 century. Besides analysised activity designer in the art deco style, at the same time considered fashion design as comparable analysis. Paul Poiret, a representative french designer, contributed to the clothing culture which accepted oriental influence and it was all the fashion enough to call the originator of present fashion. He did away with the corset, relaxed the waistline, and freed the body from clothing constrictions of almost a hundred years. Since 1914, because of industry of woman clothing that art deco represent concern of one's Chanel's perennial rival in the firmanent of parisian high fashion was the Italian designers, Elsa Schiaparelli, Schiaparelli's originalily was profoundly influenced by the avant-garde art of the time ; Da da and Surealism were principal soures of new ideas. It apply the style to geometrical or abstract form impressed straight and smooth line on suitable technic. Such inflection of art deco heralded a close collaboration between the artist-jeweller and the fashion industry. Especially, jewelry designers were fond of juxtaposing transparent faceted stoned which reflected the light, with matt stones, which offered rare or unconventional contrasts through their opacity. Consequently, art deco will exert value of utility for the progressive fashion & jewel CAD through continuous research.

Matching individual career desire and career path is desirable for individual motivation and organizational effectiveness. Some studies reported that major career orientations of MIS personnel are technical and managerial orientation. Furthermore, dual ladder system is based on the same notion above. However, subsequent research conclusions of this issues have been contradictory. Mnwhile, past studies on the work value of MIS personnel are mainly concentrated on the differences between MIS personnel and other occupations. To date, the study on the differences in the values of job factors between major career orientations is rare. The purpose of this study is to find out major career orientation of Korean MIS personnel and the differences of values of job factors between major orientations. The research result is two conclusions. First, major career orientations of Korean MIS personnel are technical and managerial orientation. Second, both group do not have different values about job property related factors, but managerial orientation group gives high values to the some organization related factors such as company policy, responsibility, authority, salary level and opportunity of promotion.

In this study, the authors analyzed the prognostic value of four clinical variables[age and sex of patients, association with myasthenia gravis and clinical stage] and histological type in 30 consecutive patients with thymoma, histologically classified as cortical[10],medullary[5] and mixed[15]type according to Marino and Muller-Hermelink classification. There were significant differences between the histological types in the frequency of the different tumor stages and myasthenia gravis and prognosis.Most of the cortical thymomas were at stage III and all of the medullary and most of the mixed tumors at stage I or II.Myasthenia gravis occurred more commonly in patients with cortical[30%] and mixed thymoma[60%] than in patients with medullary thymoma[10%]. Follow-up was conducted in 30 patients,with follow-up range from 3 months to 120 months[mean,47.3months]. 5 year actuarial survival was 100% for medullary thymoma, 73% for mixed thymoma, and 47% for cortical thymoma.The overall survival curve shows that 87.6% of the patients are alive at 2 years and 72.8% at 5 years. And 7 patients was dead during follow-up periods.By Kaplan-Meier technique, we found that the patients who had myasthenia gravis had better prognosis[P<0.05]. Medullary thymoma is a comparatively rare, benign tumor, and usually not associated with myasthenia gravis. Cortical thymoma must be regarded as malignant. Mixed thymoma is intermediate in its behavior between medullary and cortical thymoma. But these tumors should be considered potentially malignant despite of presence as stage I of II disease. Also, the patients with stageI,II had good prognosis and the patients with total resection had good prognosis[P<0.05].

The purpose of this study is to identify the distinctive characterics HYBRID, strictly defined, an offspring that is a cross between different species, genera, or, in rare cases, families, More loosely defined, a hybrid can also be a cross between parents of different subspecies or varieties of a species. Hybrid varieties of plants and animals are of economic value because the hybrid is nearly always more vigorous, larger, and more fertile than either of its parents. Plant and animal hybrids may arise spontaneously in nature or may be produced intentionally by man. Forward-looking fashion explores progress. Adjusting to a world that has integrated genetics and its mutations, the new silhouette seems without references, as if born from a spontaneous generation. A slightly bizarre composite, asymmetrical, discreetly technological aesthetic, it draws on the latest technological details. the pursuit of performance and ergonomics, yet also of comfort and amusement that takes into account the body and its articulations, generates strange garments. Inspired by medical protheses. Focos on fabric touches, their weightiness and surface effects obtained with silicone, rubber or wax. in a range that highlights yellows but can also contrast with colder, slightly surgical hues, the hybrid woman doesn't necessarily want to stand out.

Winsborough Hall built by Martin L. Winehart who was the missionary of the Presbyterian Church of America in 1927 was built by Mrs. Winsborough's birthday contribution. Winsborough Hall was clearly divided into the original form built in 1927 and remodelled form by extension. Most of walls were constructed with several kinds of bricks for both sides and opening in the original form and remodelled form. Each room divided by inner wall was kept with original form because it is difficult to remodel it on the characteristics of building. But, it was confirmed through the related literatures that security of opening at some rooms and annexation of rooms through removal of the wall on the 2nd floor which was relatively easy to transform wall compared to the first floor were made. Variability of the wall affected the truss structure of roof and it created rare double truss structure. Architectural value of Winsborough Hall was in its first architectural trial using red brick in Gwangju region since 1920s. It suggested that it was differential architectural trial from Korean-Western mixed building constructed by the missionaries from 1940 to 1910 and buildings made of gray bricks prevailed from 1911 to 1920 and it showed the advancement in the architectural structure and materials.

Ultrasonographic examination in the obstetrics not only makes easy of the diagnosis of Hydrocephalus, placenta previa, anencephalus and ectopic pregnancy, etc, but also guaranteed its excellence in the diagnosis of women gynecology disease. Especially in case that it doesn't affect radiation hazard on the embryo, its efficiency keeps increasing and it is spotlighted to many clinic doctors. Even though in general hospital we often observe congenital hydrocephalus in Med. Dept. which entirly undergoes the medical examination to the insured, we don't observe even the women delivered with child and it is very difficult to find a rare congenital hydrocephlus throughout other present insurance companies. We inspected a congenital hydrocephalus, which other medical equipments of present insurance companies have many difficulties in the medical examination, accompanied by meningoencephalocele by ultrasonic diagnosis. We analyzed and compared the data by ultrasonic diagnosis with that of surgical diagnosis and the results are follows; 1) We could correctly describe meningoencephalocele by ultrasonic diagnosis. 2) It was able to be diagnosed in LMP 22 weeks. 3) BPD has about 10 mm higher than normal value in LMP 22 weeks. 4) Dilatation of lateral ventricle was observed in LMP 22 weeks. 5) As paralled with ultrasonic diagnosis in pregnancy medical examination, accepting declines including the risk rate can be restrained.
