  • 내현적 주의와 재정향이 탐지과제 수행에 미치는 영향을 반응촉진과 회귀억제를 통해 탐색하였다. Posner와 Cohen(1980)의 고전적인 탐지패러다임에서는 단서를 제시하고 일정한 자극제시시차 후 그 단서와 같거나 또는 다른 위치에 나타나는 표적에 대한 탐지수행을 관찰한다. 본 연구에서는 내현적 주의를 유발하기 위해 단서가 표적에 대해 예측력을 가지도록 조작하였고, 단서자극과 표적 사이에 새로운 단서(재정향단서)를 삽입하여 재정향을 유도하였다. 실험 1에서는 재정향단서가 제시되는 시기를 초기, 중기, 후기로 구분하여 실험을 실시하였다. 그 결과 재정향이 제시되는 시기별로 자극제시시차(150ms, 400ms, 850ms)에 따라 다른 양상의 반응촉진 및 회귀억제가 발생하였으나, 해석 가능한 일정 패턴을 확인하기는 어려웠다. 하지만 재정향이 초기에 발생한 실험조건을 재분석한 결과, 반응촉진과 회귀억제가 자극제시시차에 따라 교차하여 나타나는 단순탐지과제의 전형적인 결과를 얻을 수 있었다. 실험 2에서는 실험 1에서 재정향이 초기에 발생하는 조건에 대한 추가 실험을 실시하였다. 실험 결과, 자극제시시차가 짧을 때는 반응촉진이 발생하였으며 자극제시시차가 길때는 회귀억제가 발생하였다. 이 결과는 단서자극이 표적에 대한 예측력을 가질 때 자극제시시차가 긴 조건에서 회귀억제가 사라진다는 기존의 보고(Wright & Richard, 2000)와 반대되는 결과이다. 이 결과는 최초 단서가 제시된 후 회귀억제의 효과가 소멸되기 전에 매우 빠르게 제시되는 재정향단서는 이중 회귀억제를 가져온다는 것을 제안한다. 본 연구는 내현적 주의에 의해 특정한 위치에 주의를 할당할 때에도 반복적으로 빠르게 제시되는 단서자극은 회귀억제를 극대화함으로써 내현적 주의를 상쇄할 수 있음을 시사한다.

  • This study is on the aesthetic characteristics of Balenciaga design succeeded to by Nicolas Ghesquiere, and tried to understand his pursuing brand's new design concept and aesthetics. The three key characteristics of Balenciaga designed by Nicolas Ghesquiere are Retrospecitvness, Eclecticism, Deconstruciton. First, Balenciaga looks retrospective sense through reinterpreting tradition. Nicolas created a new sense of expression by mixing his proper instinct with Balenciaga's original properties, historical components of the past western dress, and various design elements of assistants who used to work in Balenciaga. Second, Balenciaga expresses uncertain meaning by compromising between contrast and synthesis among the past and the future, the males and the females, simple and ornament, or different styles. Third, Nicolas's experimental and outsider-oriented view of Deconstruction through reorienting of thought is considered a try for a new formative concept as a designer who is not limited by general rules.

  • When water is evaporated quickly from a water-based colloidal suspension, colloidal particles protrude from the water surface, distorting it and generating lateral capillary forces between the colloidal particles. The protruded colloidal particles are then assembled into ordered colloidal crystalline domains that float on the water surface on account of their having a lower effective density than water. These colloidal crystal domains then assemble together by lateral capillary force and convective flow; the generated colloidal crystal has grain boundaries. The single domain size of the colloidal crystal could be controlled, to some extent, by changing the rate of water evaporation, but it seems very difficult to fabricate a single crystal over a large area of the water's surface without reorienting each colloidal crystal domain. To reorient such colloidal crystal domains, a glass plate was dipped into the colloidal suspension at a tilted angle because the meniscus (airwaterglass plate interface) is pinned and thinned by further water evaporation. The thinning meniscus generated a shear force and reoriented the colloidal crystalline domains into a single domain.

  • Korea's healthcare is in great danger of sustainability. In 2020, the baby boomer will begin to be older, and there is no promise that the total fertility rate of 1.0 or less will rebound, and Korea's economic growth rate is predicted to be less than 2%. Together with these phenomena, Plan for Benefit Expansion in Nation Health Insurance (Moon Jae-in Care) will seriously threaten the sustainability of health insurance finance. In addition, health care in Korea has many problems: excessive medical utilization, rapidly increasing elderly medical costs, concentrating patients into big hospitals, low healthcare personnel but many healthcare facilities and equipment, bad quality of primary and mental care, and fast-growing health expenditure. For sustainability, healthcare of Korea should be reformed. The direction of the reform is people-centered and integrated healthcare in the community which is composed of empowering and engaging people, strengthening governance and accountability, reorienting the model of care, coordinating services, and creating an enabling environment.

  • This paper examines A. G. Frank's views about 15th-19th Korea (Joseon Dynasty) in his Reorient. A. G. Frank recognized that Korea might have played a great role in the international relations of East Asia, but he did not write systematically about it and he did not treat Korea as an independent player in the history of East Asia. I think the greatest limitation to his re-interpretation of East Asia is in that he depends too much on China's and Japan's perspective. In order to overcome Frank's shortcomings regarding the history of Korea, first I examine what Frank recognized about the Joseon dynasty between 1400 and 1800. Next I compare Joseon's development to that of China and Japan between 1400 and 1800. Frank compared Europe and East Asia (mainly China and Japan) from three aspects of quantities (population, production, productivity, and trade), qualities (science and technology), and mechanism (economic and financial institutions). With this research we insist that Joseon should not be dismissed in 15th-19th East Asia. The reasons are as follows. First, Joseon between 1400 and 1800 had developed economically as much as China and Japan. Second, Joseon had played a great role in connecting China and Japan and had a positive influence on the development of Japan. So we need to reappraise Reorient's view about East Asia. Only when role of Joseon can be correctly estimated, the dynamics and diversity of East Asia can be properly understood.

  • Objectives: Health screening in Korea is very active in both the public and private sector. However, primary prevention for health promotion has not been activated yet. Quaternary prevention is the prevention of unnecessary medical interventions or the prevention of overmedicalization. Methods: Data was collected after a search of the literature focusing on keyword. The curriculum guidelines for family medicine residents were collected from the homepage of the American Academy of Family Physicians. Results: This quaternary prevention is just beginning. The first step to enhance the health promotion services in the community is to identify the barriers pertaining to the delivering of health promotion activities. These barriers are related to the patient, the physician, attitudes, health promotion programs and the healthcare system. The second step is to establish new changes, such as expansion of insurance coverage, improvement of medical payment system, provision of consumer-oriented services, connection and integration of providers, and the service provider education and training. Conclusions: In order to enhance the health promotion services in the community we need to identify the barriers and to establish several changes to overcome them.

  • Purpose: The purpose of this survey was to investigate clinical nurses' understanding of delirium and their educational need of delirious patient care. Method: A survey questionnaire regarding nurses' general perception and understanding of delirium, experience with delirious patients and educational need was developed and conducted with 179 clinical nurses in a university hospital in Seoul. Data was analyzed using descriptive statistics. Results: Nurses thought that delirium was one of the most important nursing problems and they considered it to be more treatable than to be preventable. However, the majority of nurses were ilot confident in caring for delirious patients. Nurses reported that delirium happened most often after surgery, and that possible contributing factors could be changes in physical environment and anxiety/stress, as well as medication and long-term isolation. Thirteen nursing interventions were identified but half of the nurses utilized only one or two of the thirteen. The most frequently used intervention was reorienting the patient followed by medication and emotional support, presenting family, and close observation. 99.5% of nurses addressed the importance of professional education on delirium care, especially in the area of intervention and management. Conclusion: The results support the strong need for development of a multi-component educational program on delirium care.

  • The aim of this paper is to show how the paradigm of disaster resilience may help reorienting urban planning policies in order to mitigate various types of risks, thanks to carefully thought action on heritage and conservation practices. Resilience is defined as the "capacity of a social system to proactively adapt to and recover from disturbances that are perceived within the system to fall outside the range of normal and expected disturbances." It relies greatly on risk perception and the memory of catastrophes. States, regions, municipalities, have been giving territorial materiality to collective memory for centuries, but this trend has considerably increased in the second half of the 20th century. This is particularly true regarding the memory of disasters: for example, important traces of catastrophes such as urban ruins have been preserved, because they were supposed to maintain some awareness and hence foster urban resilience - Berlin's Gedachtniskirche is a well-known example of this policy. Yet, in spite of preserved traces of catastrophes and various warnings and heritage policies, there are countless examples of risk mismanagement and urban tragedies. Using resilience as a guiding concept might change the results of these failed risk mitigation policies and irrelevant disaster memory processes. Indeed, the concept of resilience deals with the complexity of temporal and spatial scales, and with partly emotional and qualitative processes, so that this approach fits the issues of urban memory management. Resilience might help underlining the complexity and the subtlety of remembrance messages, and lead to alternative paths better adapted to the diversity of risks, places and actors. However, when it is given territorial materiality, memory is almost always symbolically and politically framed and interpreted; Vale and Campanella had already outlined this political aspect of remembrance and resilience as a discourse. Resilience and the territorialization of memory are not ideologically neutral, but urban risk mitigation may come at that price.

  • Purpose: The aim of this study was to compare the coordinates of anatomical landmarks on cone-beam computed tomographic (CBCT) images in varied head positions before and after reorientation using image analysis software. Materials and Methods: CBCT images were taken in a normal position and four varied head positions using a dry skull marked with 3 points where gutta percha was fixed. In each of the five radiographic images, reference points were set, 20 anatomical landmarks were identified, and each set of coordinates was calculated. Coordinates in the images from the normally positioned head were compared with those in the images obtained from varied head positions using statistical methods. Post-reorientation coordinates calculated using a three-dimensional image analysis program were also compared to the reference coordinates. Results: In the original images, statistically significant differences were found between coordinates in the normal-position and varied-position images. However, post-reorientation, no statistically significant differences were found between coordinates in the normal-position and varied-position images. Conclusion: The changes in head position impacted the coordinates of the anatomical landmarks in three-dimensional images. However, reorientation using image analysis software allowed accurate superimposition onto the reference positions.
