본 연구는 현재 영유아 이유식 브랜드 B에 대해 이용 경험이 있는 소비자를 대상으로, 인식하는 브랜드 이미지가 브랜드 관계의 질과 재이용 의도에 미치는 영향을 파악하였다. 연구 결과, 소비자가 인식하는 영유아 이유식 브랜드 B에 대한 이미지는 브랜드 관계의 질 중 자아연관, 몰입, 파트너 품질 및 친밀함에 긍정적인 영향을 미치는 것으로 나타났다. 또한 소비자가 인식하는 영유아 이유식 브랜드 B에 대한 관계의 질 중 몰입, 파트너 품질 및 친밀함은 재이용 의도에 긍정적인 영향을 미치는 것으로 나타났으나, 브랜드 관계의 질 중 자아연관은 재이용 의도에 유의한 영향을 미치지 않는 것으로 나타났다. 따라서 소비자의 영유아 제품 재이용 의도를 제고시키기 위해서는 기업은 브랜드 B에 대한 긍정적인 이미지 형성을 통해, 소비자에게 해당 브랜드에 대해 몰입 할 수 있고 파트너로서 관계를 인식 할 수 있는 마케팅 전략을 추진해야 할 것이다. 또한 소비자에게 강력한 브랜드 이미지를 인식시킨다면 타 사 제품과의 차별화를 꾀할 수 있을 것이다. 따라서 기업의 입장에서는 긍정적인 브랜드 이미지 형성이 소비자와 브랜드 간의 관계를 형성하는 핵심 요소라는 것을 인식해야 하며, 소비자가 높게 인식하는 브랜드 이미지 요소와 낮게 인식하는 브랜드 이미지 요소를 바탕으로 마케팅 전략에 활용할 수 있는 방안을 모색해야 할 것이다. 마지막으로 소비자와 브랜드 관계의 질은 긍정적인 관계 형성을 통한 재이용 횟수가 증가하나 소요되는 기간이 소비자 성향에 따라 다르고, 경우에 따라서는 오랜 시간에 걸쳐 형성되는 경우도 있으므로 장기적인 관점에서 영향력을 측정해야 할 것으로 사료된다.

Objectives: The maintenance of the healthy periodontal ligament cells of the root surface of donor tooth and intimate surface contact between the donor tooth and the recipient bone are the key factors for successful tooth transplantation. In order to achieve these purposes, a duplicated donor tooth model can be utilized to reduce the extra-oral time using the computer-aided rapid prototyping (CARP) technique. Materials and Methods: Briefly, a three-dimensional digital imaging and communication in medicine (DICOM) image with the real dimensions of the donor tooth was obtained from a computed tomography (CT), and a life-sized resin tooth model was fabricated. Dimensional errors between real tooth, 3D CT image model and CARP model were calculated. And extra-oral time was recorded during the autotransplantation of the teeth. Results: The average extra-oral time was 7 min 25 sec with the range of immediate to 25 min in cases which extra-oral root canal treatments were not performed while it was 9 min 15 sec when extra-oral root canal treatments were performed. The average radiographic distance between the root surface and the alveolar bone was 1.17 mm and 1.35 mm at mesial cervix and apex; they were 0.98 mm and 1.26 mm at the distal cervix and apex. When the dimensional errors between real tooth, 3D CT image model and CARP model were measured in cadavers, the average of absolute error was 0.291 mm between real teeth and CARP model. Conclusions: These data indicate that CARP may be of value in minimizing the extra-oral time and the gap between the donor tooth and the recipient alveolar bone in tooth transplantation.

For the combination of phosphor screens having various thicknesses and a photodiode array manufactured by complementary metal-oxide-semiconductor (CMOS) process, we report the observation of image-quality degradation under the irradiation of 45-kVp spectrum x rays. The image quality was assessed in terms of dark pixel signal, dynamic range, modulation-transfer function (MTF), noise-power spectrum (NPS), and detective quantum efficiency (DQE). For the accumulation of the absorbed dose, the radiation-induced increase both in dark signal and noise resulted in the gradual reduction in dynamic range. While the MTF was only slightly affected by the total ionizing dose, the noise power in the case of $Min-R^{TM}$ screen, which is the thinnest one among the considered screens in this study, became larger as the total dose was increased. This is caused by incomplete correction of the dark current fixed-pattern noise. In addition, the increase tendency in NPS was independent of the spatial frequency. For the cascaded model analysis, the additional noise source is from direct absorption of x-ray photons. The change in NPS with respect to the total dose degrades the DQE. However, with carefully updated and applied correction, we can overcome the detrimental effects of increased dark current on NPS and DQE. This study gives an initial motivation that the periodic monitoring of the image-quality degradation is an important issue for the long-term and healthy use of digital x-ray imaging detectors.

Myocardial tagging technique such as spatial modulation of magnetization (SPAMM) allows the study of myocardial motion with high accuracy. Tagging contrast of such a tagging images can affect to the accuracy of the estimation of tag intersection in order to analyze the myocardial motion. Tagging contrast can be affected by tagline spacing. The aim of this study was to investigate the relationship between tagline spacing of SPAMM image and tagging contrast-to-noise ratio (CNR) experimentally. One healthy volunteer was undergone electrocardiographically triggered MR imaging with SPAMM-based tagging pulse sequence at a 1.5T MR scanner (Gyroscan Intera, Philips Medical System, Netherland). Horizontally modulated stripe patterns were imposed with a range from 3.6mm to 9.6mm of tagline spacing. Images of the left ventricle (LV) wall were acquired at the mid-ventricle level during cardiac cycle with FEEPI (TR/TE/FA=5.8/2.2/10). Tagging CNR for each image was calculated with a software which developed in our group. During contraction, tagging CNR was more rapidly decreased in case of short tagline spacing than in case of long tagline spacing. In the same heart phase, CNR was increased corresponding with tag line spacing. Especially, at the fully contracted heart phase, CNR was more rapidly increased than the other heart phases as a function of tagline spacing.

Dietary life was formed as being influenced by the people's cultural, social and environmental situations. The people's food culture is unique that was adapted to their surroundings. It was developed and industrialized in the ethnic food. Now the ethnic food was contributed to tour industry or culture industry. Then, food life style was change from the meat diet to the vegetable diet in the diffusion of well-being trends. So, we analyzed Koreans' Korean food image and investigated the difference as a demographics. We made questionnaire and did a survey to 220 bloggers using cooking internet sites on 10 August, 2009. We analyzed 206 questionnaires by SPSS package 12.0 except 14 untrustworthy questionnaires. We measured credibility and validity 39 items related Korean food image: Chronbach's ${\alpha}$ was highly 0.855. We checked that KMO examination was 0.775 and $x^2$ of Barttlet was 2482.342. After verymax rotation, we deducted 5 Koran food images-healthy, visuality, spicy, variety, low calorie. We analyzed ANOVA of 5 Korean food images according to demographics. We confirmed the differences by ages, monthly income and job except academic background (p<0.05). Therefore, Korean food images were learned and recognized in everyday life. Especially, we found that visuality and variety were recognized the more stronger high-income earners and teachers than others. So, Korean learned Korean food images in real life and recognized Korean food quite differently by demographics.

The aim of this study is to examine the patterns of expressing contemporary beauty from the perspective of Laotzu's philosophy in order to suggest its concept and characteristics and to suggest specific cases through cosmetics advertisement. In doing so, the study attempted to understand that contemporary beauty is more humanistic and liberal in terms of expression patterns than in any other time period. The research results are as below. The frame concept of Laotzu's philosophy includes 1. Naturalness, 2. coexistence in Conflict, and 3. Non-otherness. The characteristics of contemporary beauty are natural and healthy, People can foresee changing beauty by the cycle of life and, by admitting this philosophy, people can understand one's individuality and discover self-esteemed beauty. Also, the results from the cases of cosmetics advertisement are as below: 1. Naturalness was remarkable. Such phenomenon was common in representative brands of the research subjects. Expression pattern was based on soft, natural make-up and hair style. 2. For conflict and coexistence, they introduced the ancient image of the situation, and the situational image using food and herbs demonstrated a functional, situational image, which was used for the cosmetics advertisement based on the mutual coexistence concept instead of dichotomy of period or material. 3. Non-otherness advertisement, of which there was none, we expected that maximized marketing effect would be achieved if non-otherness cosmetics advertisement expressed the contemporary beauty because it could solicit sympathy form many consumers.

Objectives： The aim of the present study was to determine the prevalence depressive symptoms, and the correlates of depressive symptoms, and to propose countermeasures for individual depression risk factors among college students. Methods： One university and three colleges in Jeju-do were selected as the study population and a total of 1000 students were selected by multiphasic cluster sampling to represent each department and year within each college. Of the 945 total respondents, 421 were men and 524 were women. The Beck Depression Inventory was used to evaluate depression and the BDI STEN score was used to assess depressive symptoms. Multiple logistic regression analysis was performed for comparisons. Results： 1. The prevalence of depressive symptoms among men was 14.4%, while among women the level rose to 26.8%. 2. Those with poor life satisfaction scores were significantly more likely to have depressive symptoms than those with good life satisfaction (odds ratio (OR) ＝ 2.62； (95% confidence interval (95%CI), 1.483-4.629). 3. Students over 23 years old were significantly more likely to have low levels of depressive symptoms than those under 18 (OR ＝ 0.439； 95%CI, 0.247-0.779). 4. Groups with poor body image satisfaction had higher levels of depressive symptoms when compared to respondents who had good body image (OR = 2.847; 95%CI, 1.341-6.045). 5. Students with poor perceived health status were significantly more likely to have high levels of depressive symptoms than those with good perceived health status (OR ＝ 2.029； 95%CI, 1.157-3.557). Conclusion： Universities and colleges should provide education programs, such as health education that facilitates the development of a healthy body image. In addition, they should focus on various scholarships that could improve satisfaction with student life, especially for alienated students. Furthermore, colleges should help direct students towards engagement in more productive work, and lead social policies away from the dominance of appearance.

Trigeminal neuralgia is a condition associated with severe episodic lancinating facial pain subject to remissions and relapses. Trigeminal neuralgia is often associated with blood vessel cross compression of the root entry zone or more rarely with demyelinating diseases and occasionally with direct compression by neoplasms of the posterior fossa. If initial medical management fails to control pain or is associated with unacceptable side effects, a variety of surgical procedures offer the hope for long-lasting pain relief or even cure. For patients who are healthy without significant medical co-morbidities, direct microsurgical vascular decompression [MVD] offers treatment that is often definitive. Other surgical options are effective for elderly patients not suitable for MVD. Percutaneous retrogasserian glycerol rhizotomy is a minimally invasive technique that is based on anatomic definition of the trigeminal cistern followed by injection of anhydrous glycerol to produce a weak neurolytic effect on the post-ganglionic fibers. Other percutaneous management strategies include radiofrequency rhizotomy and balloon compression. More recently, stereotactic radiosurgery has been used as a truly minimally invasive strategy. It also is anatomically based using high resolution MRI to define the retrogasserian target. Radiosurgery provides effective symptomatic relief in the vast majority of patients, especially those who have never had prior surgical procedures. For younger patients, we recommend microvascular decompression. For patients with severe exacerbations of their pain and who need rapid response to treatment, we suggest glycerol rhizotomy. For other patients, gamma knife radiosurgery represents an effective management strategy with excellent preservation of existing facial sensation.

Objective: Iris pattern recognition system is well developed and practiced in human, however, there is a scarcity of information on application of iris recognition system in animals at the field conditions where the major challenge is to capture a high-quality iris image from a constantly moving non-cooperative animal even when restrained properly. The aim of the study was to validate and identify Black Bengal goat biometrically to improve animal management in its traceability system. Methods: Forty-nine healthy, disease free, 3 months±6 days old female Black Bengal goats were randomly selected at the farmer's field. Eye images were captured from the left eye of an individual goat at 3, 6, 9, and 12 months of age using a specialized camera made for human iris scanning. iGoat software was used for matching the same individual goats at 3, 6, 9, and 12 months of ages. Resnet152V2 deep learning algorithm was further applied on same image sets to predict matching percentages using only captured eye images without extracting their iris features. Results: The matching threshold computed within and between goats was 55%. The accuracies of template matching of goats at 3, 6, 9, and 12 months of ages were recorded as 81.63%, 90.24%, 44.44%, and 16.66%, respectively. As the accuracies of matching the goats at 9 and 12 months of ages were low and below the minimum threshold matching percentage, this process of iris pattern matching was not acceptable. The validation accuracies of resnet152V2 deep learning model were found 82.49%, 92.68%, 77.17%, and 87.76% for identification of goat at 3, 6, 9, and 12 months of ages, respectively after training the model. Conclusion: This study strongly supported that deep learning method using eye images could be used as a signature for biometric identification of an individual goat.
