  • We need to establish an informative guideline to increase inter-institutional and inter-observer reproducibility of renal transplant diagnosis, and to improve the diagnostic ability of pathologists in Korea. A first nation-wide survey for renal transplant pathology was conducted by Renal Pathology Study Group of the Korean Society of Pathologists in 2016, to provide the continued excellence in the transplantation pathology laboratory, and to improve the diagnostic ability for the best treatment of transplant patients. This survey revealed the significant variations in scale, work load and biopsy indications for the renal transplant pathology in various institutions in Korea. The Banff classification were used by all institutions for the diagnosis of renal transplant pathology, but different formats were used: most institutions (70%) used the "2013 Banff classification" while the others were using "2007 Banff classification" (20%) or even older formats. In daily diagnostic practice of the renal allografts, difficulties that pathologists encounter were quite diverse due to different environments they work in. Most respondents agreed that standardized diagnostic practice guidelines, regular education on renal transplant pathology and convenient ways of consultation are further needed. We are currently working toward the enhancement of the expertise of renal pathologists and to increase inter-institutional and inter-observer reproducibility by 1) development of a set of virtual slides of renal allograft biopsies for the training, 2) validation and gathering expert's consensus on the core variables of rejection diagnosis by using virtual slides, and 3) continued education by the developed virtual slide atlas.

  • This study was conducted to investigate and analyze food related and space related elements of popular Vietnamese restaurants in Hong Kong to identify restaurant images related to food, to examine how Vietnamese traditions are applied to such restaurants, and ultimately, to get their implications for us. Luxury Vietnamese restaurants in Hong Kong tended to be located in major office buildings and famous shopping malls in the downtown area; therefore, they were highly accessible to foreigners. In addition, most Vietnamese restaurants were quite formal in size or atmosphere. The food-related elements of the luxury restaurants reproduced traditional menus, but the table setting and service generally adopted a formal Western style setting. The presentation of foods was also creative and contemporary, to suit international customers' tastes. Regarding the spatial elements, restaurants serving traditional menus had interiors influenced by the French colonial period, while those serving contemporarily adapted menus had interiors with simple contemporary images emphasized by Vietnamese traditional decorations. These characteristics allowed foreigners from diverse countries to access the restaurants without a sense of rejection. Casual restaurants were primarily exposed to many people on busy roadsides, but they tended to be inferior in terms of size and quality. Apart from size and price level, food-related elements failed to reflect Vietnamese unique traditional characteristics. The outward appearance consisted of basic construction materials (glass, chassis, and bamboo) instead of those representing Vietnamese architecture. Additionally, the interior of the casual restaurants contained traditional elements or objects more frequently than luxury restaurants, but they looked rather disorderly and lacked harmony. Overall, the image of casual restaurants was degraded by the use of cheap and low quality finishing materials and furniture. The results of this study may be useful for organizations promoting the Branding of Korea or businesspeople and designers promoting the globalization of Korean foods.

  • Background: Tuberculosis (TB)-related stigma has been well-documented. Since the emergence of the coronavirus disease 2019 (COVID-19), different organizations have been alerted to the fact that stigma could arise again. Due to stigma's negative effects, this qualitative study aimed to explore the stigma felt by patients by evaluating the following: COVID-19 stigma and its temporal progression through the pandemic; stigma perceived by different patients with TB before and during COVID-19 pandemic; and difference perceived by individuals who contracted both diseases. Methods: A semi-structured interview was developed according to the available literature on the theme. It was performed individually in 2022 upon receiving signed informed consent. Participants were recruited with a purposive sampling approach by searching medical records. Those who currently or previously had pulmonary TB and/or COVID-19 were included. Data were subjected to thematic analysis. Results: Nine patients were interviewed, including six (66.7%) females. The median age of patients was 51±14.7 years. Four participants (44.4%) had completed high school and four (44.4%) were never smokers. Three had both TB and COVID-19. Four only had TB and two only had COVID-19. Interviews identified eight main themes: knowledge and beliefs, with several misconceptions identified; attitudes towards the disease, varying from social support to exclusion; knowledge and education, assumed as of extreme importance; internalized stigma, with self-rejection; experienced stigma, with discrimination episodes; anticipated stigma, modifying actions for avoiding stigma; perceived stigma, with judgment by others prevailed; and temporal evolution of stigma. Conclusion: Individuals expressed strong stigma for both diseases. De-stigmatization of respiratory infectious diseases is crucial for limiting stigma's negative impact.

  • Blood test is a useful tool in establishing medical treatment for livestock. It provides information such as disease diagnosis, treatment effects, prognostic judgment, and health status. This study compared the value of erythrocytes and leukocytes among conventional, transgenic miniature, and transgenic conventional pigs aged six months to 24 months. Further, it analyzed the aspects of hematological value changes according to the pigs' ages. As a result, the number of red blood cells (RBC), which include hemoglobin, and hematocrit, and the number of white blood cells (WBC), which include neutrophils, and lymphocyte, were high among transgenic miniature pigs, compared with the conventional and transgenic conventional pigs. Conventional pigs showed similar values of RBC and WBC regardless of transgenesis. In comparing their age, the RBC decreased as the age increased compared with the pigs among all the three groups aged of 6~12 months. On the other hand, WBC and neutrophils showed no significant difference regardless of different ages among all the three groups. However, various counts in RBC and WBC were mostly found to be higher in each age in transgenic miniature pigs than in conventional and transgenic conventional pigs. The results of this study show that the values of RBC and WBC were generally higher in transgenic miniature pigs than in conventional and transgenic conventional pigs. Based on this research, hematological values can be widely used in diagnosing diseases or checking the health status of transgenic pigs that are used as disease models, organ transplant source and alike.

  • 최근의 소비자들은 기업이 우리 사회가 직면한 문제들과 맞서 싸우며 사회 변화를 위하여 관심을 가지고 행동하기를 기대한다. 이에 본 연구는 우리 사회의 주요 이슈와 관련된 사회적 목소리를 담은 네이티브 광고에 대한 효과를 규명하고자 하였다. 특히 본 연구는 사회적 목소리를 담은 네이티브 광고의 주체와 개인 특성인 윤리적 소비 성향에 따라 그 효과가 어떻게 나타나는지에 대하여 주목하였다. 그리고 소비자는 기업이 후원한 네이티브 광고보다 기업이 직접 제작한 네이티브 광고에 대해 부정적 기업 태도를 보일 것이며, 소비자의 윤리적 소비 성향에 따라 이러한 효과가 달라질 것이라는 가설을 제안하였다. 일련의 가설을 검정하기 위하여 직장인들을 대상으로 온라인 실험을 진행하였다. 연구 결과에 따르면, 사회적 목소리를 담은 네이티브 광고에 있어서 주체를 기업이 직접 제작이라고 표기했을 때와 기업이 후원하였다고 표기하였을 시 소비자의 기업 태도는 차이가 나타나지 않았다. 그러나 소비자의 개인 특성인 윤리적 소비 성향에 따른 유의한 차이를 발견할 수 있었는데 윤리적 소비 성향이 높은 소비자의 경우 사회적 목소리를 담은 네이티브 광고의 주체로 기업이 제작하였다는 표기보다는 기업이 후원하였다고 표기한 경우 기업 태도가 높게 나타났다. 이와 같은 연구의 결과는 광고 표기의 명료성에 관한 관심이 높아지는 현시점에서 네이티브 광고의 주체 및 표기에 대한 효과를 밝히고 이러한 효과에 영향을 미치는 개인 특성 변인을 규명하였다는 점에서 연구의 함의를 찾을 수 있다. 또한, 실무적으로 기업이 사회적 목소리를 담은 네이티브 광고를 집행할 시에 윤리적 소비 성향이 높은 소비자들의 기업 태도를 높이기 위해서 광고 주체 및 표기를 더 세심하게 재고해야 할 필요성이 있음을 시사해준다.
