  • This study investigated and compared the tasks peformed by Consumer Agencies in Korea and Japan. It also investigated the variables influencing evaluation scores on consumer tasks. The results of this study are summarized as follows. First, Japanese counselors were predominantly older, married females in contrast to the predominance of relatively young, single, male, Korean consumer counselors. In Korea, most consumer tasks were performed by Consumer Agencies in Seoul while internet counseling was popular. In addition, 13 counselors belong to Korean Consumer Agencies while 80 worked in the Korea Consumer Protection Board. In Japan, consumer tasks were peformed by Consumer Centers located broadly across the nation but no internet counseling was provided, while the average number of consumer counselors per Consumer Center was 8. The average number of consumer counseling sessions per day was greater in Korea than in Japan while the average monthly income was higher in Japan than in Korea. Second, evaluation of the tasks performed by Consumer Agencies revealed that the Korean Consumer Agencies scored higher performance than their Japanese counterparts. Third, the degree of job satisfaction significantly influenced evaluation scores in both consumer counseling tasks and provision of consumer information in Korea. In Korea, among the tasks concerning consumer education, job-training education was a significant variable while the number of Korean counselors in Consumer Agencies positively influenced scores on activities concerning consumer movement and alliance with other agencies. However, the degree of job satisfaction among counselors positively and significantly influenced evaluation scores in tasks concerning consumer counseling, provision of consumers'information, and consumer education. On the other hand, the number of counselors in Japanese Consumer Centers influenced the evaluation scores on tasks concerning consumer policy, consumer survey, and consumer campaign.

  • Actin binding proteins play key roles in cell structure and movement particularly as regulators of the assembly, stability and localization of actin filaments in the cytoplasm. In the present study, a cDNA clone encoding an actin bundling protein named as AhABP was isolated from Acanthamoeba healyi, a causative agent of granulomatous amebic encephalitis. This clone exhibited high similarity with genes of Physarum polycephalum and Dictyostelium discoideum, which encode actin bundling proteins. Domain search analysis revealed the presence of essential conserved regions, i.e., an active actin binding site and 2 putative calcium binding EF-hands. Transfected amoeba cells demonstrated that AhABP is primarily localized in phagocytic cups, peripheral edges, pseudopods, and in cortical cytoplasm where actins are most abundant. Moreover, AhABP after the deletion of essential regions formed ellipsoidal inclusions within transfected cells. High-speed co-sedimentation assays revealed that AhABP directly interacted with actin in the presence of up to $10{\mu}M$ of calcium. Under the electron microscope, thick parallel bundles were formed by full length AhABP, in contrast to the thin actin bundles formed by constructs with deletion sites. In the light of these results, we conclude that AhABP is a novel actin bundling protein that is importantly associated with actin filaments in the cytoplasm.

  • The nineteenth century was a watershed - the extreme point of difference in the style of fashion dress and in the roles men and women played in society. This conviction has its roots in the socioeconomic changes of the 19th century and the industrial revolution, and the new working bourgeoisie' value, fashion and taste were on the rise. The bourgeois, who was not considered as having infallible taste, was looking for its own style, while on the other hand it was competing with the nobility. Therefore bourgeois' own etiquette and taste were appeared. There was ideals which the middle classes were hungry for, and it became the basis of judging an individual. The bourgeois tried to get social approval and used fashion was the mean of it. Bourgeois women fashion has a funtion as a complete symbol of the status, wealth and leisure in a patriachal society. Not only the Bourgeois tried to control themselves and to achieve the virtue of moderation, chastity and obedience by the restrictive costume, but also extravagant and cumbersome dresses has a kind of compensative funtion against a sober and simple men's dress. There was a reformative movement to break out of the legal, economic and social restrictions within the confines of respectable Victorian Society. The process of reform was long and slow for not only did laws be changed but the barriers of prejudice in a society convinced of man s mental and physical superiority had to be overcome. But even though there were many difficulties, a small number of progressive women challenged the social recognition and role of women and decisively refused the restrictive and ostentative fashion. Victorian costume was also criticized in the medical and aesthetic aspect for their impracticality. As a result, more funtional and practical women's clothes has appeared, but it have resulted in a peculiar hybrid of traditional female attire in combination with the more uncomfortable aspects of men's clothes. However it was becoming an essential look for new women who were the equals of men and wanted to be treated as such.

  • Purpose: The cerebellum is a region of brain structure that plays an important role in calibrating two different information of neural signal from descending motor commands and from ascending sensory inputs. Damage of the cerebellum shows a variety of classic motor symptoms such as postural and locomotor dysfunctions. Therefore, we tried to investigate motor function and skill in stroke patients with cerebellar lesions in sub-acute stage, and compare with these functions of patients with non-cerebellar lesions. Methods: Total twelve stroke patients with cerebellar lesion and 130 stroke patients with non-cerebellar lesions were retrospectively recruited in this study. For evaluation of motor strength, Motricity index (MI) for upper and lower limbs was tested. For measurement of motor skill function, the modified Brunnstrom classification (MBC), Manual function test (MFT), functional ambulatory category (FAC), and Barthel index were adopted. Results: In comparison of motor strength and motor skill function between two groups, statistical differences between the two groups were significantly observed only in upper MI and FAC. Although no significant differences were found in other variables, stroke patients with cerebellar lesion had higher scores in lower and total MI, MBC, and MFT, whereas they had lower scores in FAC and Barthel index. Conclusion: Our results showed that stroke patients with cerebellar lesion had greater impact on movement functions related to hand motor and walking ability in activities of daily life, compared with patients with non-cerebellar lesion, in spite of similar degree of motor function and skill between the two different lesioned-groups.

  • In the present study, the anticonvulsant effects of Artemisia capillaris Herba (AC) and its major constituent, esculetin (ECT), were tested and the mechanism studied. Locomotion, Myorelaxation, motor coordination and electroshock seizure experiment were conducted in mice. To identify the anticonvulsant mechanism effect of this drug, chemical-induced seizure in mice and the ionic movement in neuroblastoma cells were also observed. The ethanol extract of AC was orally administered to mice 30 min. prior to testing and ECT was intraperitoneally injected. AC and ECT treatment did not change locomotor activities as well as activities on the rota-rod, which indicates that they did not cause a sedative and myorelaxation effect. AC and ECT treatment increased threshold of convulsion induced by electroshock. AC treatment also inhibited convulsion induced by pentylenetetrazole. In the case of strychnine however, only high dose of AC treatment inhibited convulsion. AC and ECT treatment increased the $Cl^-$ influx into the intracellular area in a dose-dependent manner. On the other hand, bicuculline, a GABA antagonist, inhibited the $Cl^-$ influx induced by AC and ECT. These results indicate that ECT induces the anticonvulsive effect of AC extract through the GABAergic neuron.

  • 바우하우스운동은 하나의 디자인 관이 전제되어 일관성 있게 진행되었다 기보다는 소위 근대와 반 근대의 끊임없는 갈등 속에서도 구성원들의 일관된 삶의 방식을 통하여 추구된 조형작업의 부산물이라 할 수 있다. 따라서 현대디자인의 근원을 형성하는데 기여했던 바우하우스 교육의 모든 기구는 학생이 모든 내적, 외적 곤란을 극복하는 시점에서의 실제문제와 관계 있는 교유 가치를 실현하는데 있었으며 교육과 생산이 하나의 시스템 속에서 가장 효율적으로 운영될 수 있는 최소단위로서의 작업공방이 필연적으로 생겨나게 된 것이다. 바우하우스 공방작업의 가장 본질적인 점은 시간이 지나면서 모든 제품이 균질성을 나타낸다고 하는 사실이며 이것은 각양각색의 인격과 개성의 협력을 바탕으로 삼아 의식적으로 발달한 공동체 정신의 결과로서 나타난 것이었다. 또한 이 균질성은 외견상에 나타난 양식 적인 세세한 면에 있는 것이 아니라 사물을 간결하고 충실하게, 한편으로는 본질적인 법칙에 응해서 만들어 낸 노력에 기초하고 있다. 따라서 바우하우스 제품의 원형은 유행적인 것이 아니라 예술, 기술, 경제에 따른 형태 부여라는 점에서 수많은 사고와 심사숙고를 거친 공방 작업과정의 결정체라고 볼 수 있다.

  • This study, with teachers form elementary schools in Chungju-si as its subjects, has investigated influence of school forest on satisfaction with school greenspace and environmental education. It has reached the following conclusions. As for recognition of and satisfaction of school greenspace there were meaningful differences between teachers form school forest model schools and ones from common schools, which was thought to be due to positive effects of school forest movement. It appeared that environmental education was carried out through audio-visual materials once a week in most schools. On the other hand, as for class places, 'classroom in parallel with outdoor class' and 'classroom education' appeared to be carried out most frequently in the case of school forest model schools, and 'classroom education' in the case of common schools. However, considering the fact that 'field learning' the most important element in environmental education, appeared to be carried out least frequently in both of the groups, which suggests that we should improve it for future through introduction of various field-experience learning programs. As a result of the survey of satisfaction with environmental education, some meaningful differences were recognized between school forest schools and common schools, and 'presence or absence of field learning spaces' was the most frequently answered reason for 'satisfied' and 'unsatisfied'. Thus, 'schools' and related institutions' enthusiastic efforts are needed for providing field-experience spaces where children can directly access to and explore into nature.

  • The purpose of this study is to suggest planning strategy of tenant mix for UEC based on the final result of tenant mix analysis of five different research cases. The following is the comprehensive explanation about the result of tenant mix planning strategy for UEC currently in operation and when planning a new facility. First, overall research cases in this study show the tendency of following an old tradition, which stresses direct sales focusing on retail and dining adaptation. In order to compensate the defect, it is suggested to adopt new type of tenants with the functional mix of retail and dining with entertainment rather than decreasing the proportion of retail and dining tenant and increasing it of entertainment tenant. Second, the floorplan of UEC should adopt racetrack or circuit form that can stimulate shoppers' circular movement so to expose them to as much tenants as possible. Service consumption mode related tenants are required to place on the side or the edge of UEC, while retail consumption mode related tenants should be planned in the center. Among dining consumption mode related tenants, impulse dining tenants like a coffee shop should be placed at the turning point or at the end of the pathway, destination tenants like a restaurant and a food court, on the other hand, is needed to be placed in the center of the space. In case of Entertainment related tenants, destination tenants like bookstore or multiplex should also be placed at the end of the pathway, and on the way to those tenants, it is required to place general tenants that can share target customers with them. On the contrary, game center or record shop like tenants that can stimulate impulse sales should be placed on the visitor's main move or near the other destination tenants. Third, anchor tenants play an important role in gathering people to the UEC, and then induce them to visit the other tenants that are located near the anchors. Thus it is suggested to plan to place general tenants on the same floor as anchor tenants are placed so they can share the characteristics of target customers which create synergy effect.
