Purpose: For several decades, open reduction has been a controversial issue in mandibular condyle fracture. The authors have successfully used the open reduction and internal fixation with retromandibular approach and have found it to be satisfactory for mandibular condyle fracture. Methods: A total of 10 patients with mandibular condyle fracture underwent open surgical treatment using retromandibular approach. The incision for the retromandibular approach was carried below the ear lobe and the facial nerve branches were identified. Dissection was continued until the fracture site was exposed and internal fixation was performed with miniplate following intermaxillary fixation. The average period of joint immobilization was 1 weeks and the arch bars were removed in 3 weeks on average. The preoperative and postoperative panoramic view and three-dimensional computed tomography were compared. During the follow up period, we evaluated the presence of malocclusion, chin deviation, trismus, pain, click sound, facial nerve palsy, hypertrophic scar and skin fistula. Results: According to the radiographic findings, the fractured condyle was reducted satisfactorily in all patients without any symptoms of facial palsy. During the follow up period ranged form 6 to 12 months, all clinical symptoms were improved except in one case with chin deviation and malocclusion. Conclusion: Using open reduction and internal fixation of mandibular condyle fracture with retromandibular approach, all results were satisfactory with good functional outcomes and minimal complication. We concluded that the open surgical treatment should be considered as the first choice for mandibular condyle fracture management.

The Influence of Art-provoked Affect on Product and Product Attributes Evaluation

김한구,정보희,주우진 한국마케팅학회 2011 ASIA MARKETING JOURNAL Vol.13 No.2

In recent years, a new way of differentiating product design has emerged―better known as ‘masterpiece marketing,’ this is a strategy where famous art pieces are borrowed on to product designs. Because the recent trends of well-being and LOHAS have encouraged the consumers’ desires to enjoy culture and live a more opulent lifestyle, famous and notable paintings have grown to be more of “approachable masterpieces” to the public. As a strategy intended to develop a new consumerism, while still prioritizing customers’ values and their satisfaction, companies have been drawn to this new type of marketing. The current consumption society has converted renowned art pieces from simply works of ‘high culture’ to a further way of marketing, aimed to differentiate products and dominate the market. Though many products have had masterpieces applied to their designs and have been noticed for their marketability, there has been less systematic research done on the scientific background behind this marketing approach. This research focused on the art pieces’ fundamental nature of inducing emotions in the viewer, and hypothesized about how the evaluation of a product may be influenced by the affect provoked by the art piece used. To be more specific, if art pieces with different levels of pleasure and arousal―the two axis of emotion suggested by existing research on emotion―were used on each product, the goal was to see how the different levels influenced the consumer’s assessment of the products, focusing on product’s type as well as the evaluation of their attributes. First, a pretest was done to verify the relationship between the emotion provoked by the art piece and the consumer’s preference. There were two types of surveys, each with five drawings from the ten that were assumed to differ in levels of the two axis of emotion. The survey was composed of questions asking for positive emotion, negative emotion, level of arousal, and preference. The correlation between the measurements of positive and negative emotions was -0.792, so an integrated entry was used in the analysis by subtracting the measurement of negative emotions from that of positive emotions. The first hypothesis that paintings that provoke positive emotions will be more preferred than paintings that bring out negative emotions was supported; and through this research, paintings that were to be used for the products were selected. The second pretest was conducted to settle on an item that would be used in the research. Items meant to measure utilitarian and hedonic attributes of milk and chocolate, the two products to be used in the research, were extracted. Because milk is a utilitarian product with strong practical attributes while chocolate is a hedonic product with strong hedonic attributes, these two were selected to be used in this research. The first study was executed to see if there is a difference in attitude about products that have different painting on their designs, which either induces positive or negative emotions. It was also to verify whether this difference in attitude was mediated by the viewer’s preference for the art piece. This study showed that when positive emotion inducing painting was used, the product was better evaluated compared to the product with a painting that provokes a negative emotion, thus supporting the second hypothesis. It was also supported that the effect of affect on product evaluation was mediated by preference for the art piece. The second study was done to see the influence of the level of arousal on the evaluation of the product’s attributes. Art pieces that differ in the level of arousal were selected through the pretest, and later it verified the hypothesis that the level of arousal has an effect on the assessment of the attributes of the product. In the case of milk, a utilitarian product, the fourth hypothesis that a high-arousal painting will better evaluated for its hedonic attribute...

한국 학생운동의 사회인류학적 고찰

This study attempts to analyze the structure and function of Korean student' movements that have emerged during the period of 1910's ∼1980's. From a social anthropological standpoint these movements may be classified into the two Major Categories: (1) Nationalistic student' movements; (2) Antibureaucratic students' movements The former emphasizes Korea's independence from Japanese anne- xation, while the latter strongly protests the nation's and university's bureaucratization and elitism. Several authors have identified those which had occured particularly during the period of Japanse annexation(1910's∼1940's), categoric- ally with Anti-Japanese Independent Movements by the Korean Stu- dents. The present study, however, points it out that they are, in fact, revitalization movements which may be defined as "a deliberate, conscions, organized effort of members of a society to construct a more satisfying culture. On the other hand, many writers have also suggested that those movements launched by the Korean students during the period of 1940's∼1980's are Anti-governmental, Political Movements. But from a comparature sociological perspective this thesis defines them as Anti-bureaucratic, Social Movements whivh emphasize the changes in the existing socioeconomic and power structures. In short they are social rather than political in the final analysis. Finally, this study concludes that in general, a series of Korean students' movements emerging since 1910's up to present(1980's) are a prime mover of Korea's social and cultural transformations mainly through the processes of their Cultural contact and acculturation.

Effect on Friction of Engine Oil Seal with Engine Oil Viscosity

김한구,전세일 한국자동차공학회 2008 International journal of automotive technology Vol.9 No.5

Low viscosity engine oil can improve a vehicle’s fuel economy by decreasing the friction between the engine components. Frictional torque varies with the velocity change due to different viscosity characteristics of SAE grade 5W-20, 5W-30 and 5W-40 engine oils. The viscosity for each of these grades was measured to outline the effect low viscosity engine oils have on engine friction, which may lead to improved fuel economy. Engine oil seal frictional torque increases with the shaft rotational speed for all three engine oil grades. A decrease in engine oil seal frictional torque was confirmed when low viscosity engine oil was used. Also, the leak-free performance of the engine oil with the seal satisfied the life limit durability test criteria. Thus, low viscosity engine oil may be used to improve fuel economy by decreasing the frictional loss of the engine oil seal while having no negative impact on performance due to leak-free functioning.

This study is an analysis of the genesis and development of Tonghak, and its effect on modern Korean society. It demonstrates that the Tonghak movement was an organized religious complex which brought about significant social and cultural change in Korea, and that this movement can best be comprehended as an acculturation phenomenon in Korean society. Tonghak(now known as Ch'ondokyo) was the Christian-like monot-heistic and hierarchically organized religion to appear in Korea. Its doctrine was first proclaimed in April, 1860 by the prophet Ch'oe Che-U(1824~1864), a Korean native. Tonghak doctrine is essentially a statement of belief in the Tonghak God, Ch'onju(Heavenly Master or Lord), and an affirmation of obedience to his will and way. It offered the believers hope of long life in the (Tonghak) paradise on earth, which would arrive through the intervention of Ch'onju. In order that the whole nation might share share in the coming paradise, the Tonghaks zealously Propagated their doctrine, urging all the Koreans to give up their old religious beliefs and to become Tonghak followers. In this study of Tonghak it is argued that the Cumulative western impact upon the Korean people from Ca. 1787 to the 1860's should be considered as the most vital aspect in defining the genesis of Tonghak and in understanding its total nature. It is explained that Tonghak's emergence in 1860 directly resulted from this impact, and Tonghak is regarded as a religiously oriented acculturative revializaion movement. The movement was characterized by the process of the Tonghak Korans sequential, conscious and deliberate acculturation to the west. It is also pointed out that a religiously oriented acculturative revitali-zation movement can appear among the native peoples when the degree of wester nimpact upon them becomes extreme. According to his investigation, movements similar to Tonghak occurred during the nineteenth and twenteth centuries among the Indians in parts of North America, the native peoplesia, and the Chinese peasants in T'ai-ping China from 1851 to 1864. Thus, the conclusin differs from the explanaion given by other writers who argue that Tonghak's appearance was a king of spontane-ously organized, wide-spread native rebellion resulting principally from internal confilcts, chiefly the economic and political oppression of the Korean people by the indigenous ruling elite.
