팬데믹(Pandemic)으로 인해 온라인 시장의 규모가 급속하게 커졌다. 일상에서의 비대면화는그동안 기술수용에 늦은 소비자마저 온라인구매의 편리함을 경험하게 하는 계기가 되었고, 이들은 팬데믹 이후에도 온라인구매의 이점을 선호하게 될 것이다. 하지만 이러한 변화의 시기에 소비자가 취할 수 있는 제품 정보는 편평한 디스플레이상의 시각적 정보만으로 축소되었다. 회사들은 차별적이고 경쟁력 있는 정보를 제공하기 위해 AR/VR, Streaming 기술 등을 도입하고 있지만, 정직한 사용자들이 남긴 리뷰는 회사가 제공하는 잘 가공된 정보만큼 소비자에게 강력하게 인식되고, 회사의 상품개발과 마케팅 및 판매 전략을 위한 인사이트를 얻을 수 있다는 점에서 중요하게 인식될 필요가 있다. 그렇다면 소비자의 입장에서, 구매 의사결정 전에 참고하는 리뷰의 평점이 크게 어긋난다면, 소비자들은 어떻게 리뷰정보를 처리할까? 수렴되지 않은 평점은 늘 신뢰할 수 없고 가치 없는 것일까? 본 연구에서는 소비자의 개인 성향으로 볼 수 있는 조절초점 성향이 어떻게 사고방식을 지배하여 수렴되지 않은 정보를 수용하고 처리하는지 보이고자 하였다. 실험은 화장품을 대상으로 제품 리뷰 평점의 분산(높음 vs 낮음)이 소비자의 조절초점(예방초점 vs. 향상초점)에 따라 제품 태도에 어떤 영향을 미치는지 2x2 연구로 설계하였다. 연구결과, 예방초점의 소비자는 분산이 작을 때 높은 제품 태도를 보이지만, 향상초점의 소비자는 분산이 클 때 높은 제품 태도를 보인다는 것을 발견하였다. 이와 같은 연구로, 본 논문은 동일한 평균값의 평가점수를 가진 제품이라도 후기의 분산 값에 따라 소비자의 조절초점 성향이 영향을 미쳐 제품 태도가 달라진다는 것을 설명할 수 있다. 본 논문은 평점이 수렴되지 않는 정보에 대한 소비자의 정보처리의 메커니즘을 밝힌 이론적 공헌이 있으며, 실무적으로 기업은 리뷰가 축적됨에 따라 개인화되고 최적화된 상품 정보를 제공하는 등 빅데이터를 바탕으로 지식경영을 응용한 고객경험설계가 가능함을 시사한다.

This Study has been carried out to make a recommendation for the next amendment of the Infectious Disease Prevention Act with a specific focus on the kind of notifyable disease. Korean, Japanese, German, U.S, English and French acts on infectious diseases prevention were reviewed, compared with and analized in regards of numbers and kinds of notifyable infectious diseases and their tendency of amendments. An criteria was designed to assess the level of validity of diseases to be designated in the act. Four items, the fatality (greater than 10% or not), the possibility to make a big epidemic, the availability of efficient vaccination and the usefulness of isolation, are used in the assessment. This index is applied to the diseases in Korean and other countries' Infectious Disease Prevention Acts. Results are as follows: 1. The Korean Infectious Disease Preventon Act has a unique way of classifying the notifyable infectious disease, that is, the first, the second and the third class. But the author cannot find the basis of classification. No other countries reviewed have the similar classification. 2. The ten diseases, cholera, plague, yellow fever, diphtheria, typhoid fever, poliomyelitis, rabies, tetanus, malaria, and meningococcal meningitis are designated as the notifyable diseases not only in Korea but also in Japan, Germany, United States, England and france. 3. Thirty seven diseases including small pox, Lassa fever, anthrax, influenza, German measles, Legionellosis, infection with E. coli O157:H7, Q-fever, brucellosis, Lyme disease are designated as legal disease at least one of the above mentioned countries. 4. The Korea has been coped with the change of the infectious disease occurrence for last fifty years in amendment of the Infectious Disease Prevention Act. 5. Japan has a special infectious surveillance system composed of 3,880 clinics throughout the whole country. 6. Germany has classified infectious diseases in five categories which are based on seriousness of disease. Any confirmed death, cases and suspected cases in class I should be reported within 24 hours. But only confirmed death and cases in class II, but not suspected cases, are reportable in Germarny. 7. Plague, bacillary dysentery, pertussis, mumps, Japanese encephaltis and Korean hemorrhagic fevers are diseases with high credits validity index among Korean legal disease. 8. German measles, anthrax, E. coli O157 : H7 infection, Lassa fever, Q-fever, brucellosis are high in validity index among those which are not designated in Korea but designated in other countries. In conclusion, the Korean Infectious Disease Prevention Act has well been coped with the changes of infectious disease occurrence for last fifty years, but the classification basis and the validity of diseases to be designated as legal diseases is worth reevaluating.

Despite recent breakthroughs in deep learning and computer vision fields, the pixel-wise identification of tiny objects in high-resolution images with complex disturbances remains challenging. This study proposes a modified U-net for tiny crack segmentation in real-world steel-box-girder bridges. The modified U-net adopts the common U-net framework and a novel Self-Attention-Self-Adaption (SASA) neuron as the fundamental computing element. The Self-Attention module applies softmax and gate operations to obtain the attention vector. It enables the neuron to focus on the most significant receptive fields when processing large-scale feature maps. The Self-Adaption module consists of a multiplayer perceptron subnet and achieves deeper feature extraction inside a single neuron. For data augmentation, a grid-based crack random elastic deformation (CRED) algorithm is designed to enrich the diversities and irregular shapes of distributed cracks. Grid-based uniform control nodes are first set on both input images and binary labels, random offsets are then employed on these control nodes, and bilinear interpolation is performed for the rest pixels. The proposed SASA neuron and CRED algorithm are simultaneously deployed to train the modified U-net. 200 raw images with a high resolution of 4928 × 3264 are collected, 160 for training and the rest 40 for the test. 512 × 512 patches are generated from the original images by a sliding window with an overlap of 256 as inputs. Results show that the average IoU between the recognized and ground-truth cracks reaches 0.409, which is 29.8% higher than the regular U-net. A five-fold cross-validation study is performed to verify that the proposed method is robust to different training and test images. Ablation experiments further demonstrate the effectiveness of the proposed SASA neuron and CRED algorithm. Promotions of the average IoU individually utilizing the SASA and CRED module add up to the final promotion of the full model, indicating that the SASA and CRED modules contribute to the different stages of model and data in the training process.

Purpose: The purpose of this study was to explore the perception of infertile women on the use of the national support program that provides medical expense aid to infertile couples. Methods: Thirty Korean infertile women participated in five focus groups. Data were collected from January to August 2014. After obtaining permission from the participants, each session of the focus group was audio-taped and transcribed. The responses were analyzed using qualitative content analysis. Results: The main themes identified from the sessions with the participants were "feeling thankful for the reliable support program," "feeling happy or unhappy," "enduring inconveniences," and "hoping for a more comprehensive support service." Although most of the participants perceived the benefits of the national support service positively, they stated that the service was not comprehensive because it did not cover all the medical expenses for tests and other medical treatments. Conclusion: The benefits given to infertile couples by the program should be increased by covering all the medical expenses, expanding its criteria to include more eligible candidates, and by including special leave benefits for working women. Furthermore, it is essential to take measures for infertility prevention at the individual and national policy levels.

Eating behavior change as a result of nutrition education interventions as secondary prevention strategies can contribute to an increase in life expectancy and better health for older adults in the United States (U.S.). Many of the chronic conditions prevalent in older adults are modifiable by dietary changes, including heart disease, diabetes mellitus, hypertension, obesity and osteoporosis. Important demographic observations in the U.S. including the projected large increase in number of older adults by 2030 have implications for nutrition education focus and services. A comprehensive review of nutrition education interventions for older adults in the U.S. published in 1995 identified elements from adult education theories that contribute to the effectiveness of nutrition education. These elements have been the focus of more recent studies with older adults providing additional evidence for relationships between concepts from commonly used behavior change theories and dietary patterns or change. In the U.S, an important program contributing to nutritional adequacy of the diet for older adults is the Elderly Nutrition Program which provides resources for congregate dining and includes a mandatory nutrition education component. Nutrition education is also provided through clinic based programs, and print and broadcast media. Application of the Transtheoretical Model has shown that the level of interest or motivation to comply with dietary guidance may be greater for some older adults due to an increasing burden of chronic disease and poorer quality of life, while others may not feel a need to change lifestyle habits.

Depending on changes in industrial structure, industrial accident preventive measures have been developed in various forms. The focus for prevention of industrial accidents had been changed from part of the hardware to behavior and consciousness of workers. According to the change of focus, Korea's industrial accident preventive measures also has been adjusted to voluntary safety and health considering the safety culture and such attempts of preventive measures has contributed for reducing the accident rate. Safety culture is difficult to access due to the fact that factors that make up the safety culture are comprehensive and varied and there are many of external factors that affect to the safety culture. Moreover, there is a limit for applying specific preventive measures. Because, management culture or value of enterprises is various depending on each country or region. Nevertheless, looking at previous studies of advanced countries, they are presenting the fact that safety leadership has greater influence to formation of the safety culture. As a result, we study the Influence of manager's safety leadership that effect on safety culture. we want to propose the way to activate safety culture in workplace and to contribute for safety culture research.

Background: The industrial revolution that took place in the United Kingdom (UK) between 1760 and 1830 led to profound social change. Occupational medicine was concerned with the diagnosis, treatment, and prevention of occupational diseases, that is, diseases directly caused by exposure to workplace hazards. A similar pattern of development has occurred globally. Methods: A review of relevant literature. Results: The international conceptualization and development of occupational health occurred during the 20th century. A new paradigm for occupational health has emerged that extends the classical focus on what might be termed "health risk management" that is, the focus on workplace hazards and risk to health to include the medical aspects of sickness absence and rehabilitation, the support and management of chronic noncommunicable diseases, and workplace health promotion. Conclusion: The future strategic direction for occupational health will be informed by a needs analysis and a consideration of where it should be positioned within future healthcare provision. What are the occupational health workforce implications of the vision for occupational health provision? New challenges and new ways of working will necessitate a review of the competence and capacity of the occupational health workforce, with implications for future workforce planning.
