This study evaluated economic feasibility and provided rationale for the development of the Korean Operational Oceanographic System (KOOS). KOOS is supposed to be established for the preservation and management of marine environments, and for the safety of ocean activities. Economic issues associated with operational oceanographic systems are discussed. During the operational period of KOOS associated with conservative small-input scenarios, and according to the macroeconomic inputoutput analysis, the system was estimated to generate 8.3 times its actual proposed economic investment (about KRW 327.7 billion). Other rationales that cannot be easily quantified were also discussed.

This study was to describe the process on experiences of self-leading leisure activities and develop a substantive theory that explains lifestyle in middle-aged office workers. The participants were 12 persons who had participated in self-leading leisure activities. Data were collected with in-depth interviews and analyzed by grounded theory in Strauss and Corbin. Through analyzing process, 28 concepts, 14 subcategories, and seven categories were deduced. The periods of process were divided four stages, plateau, the phage of recognition in social duties, the phage of strengthen in competency, and the phage of reconstruct in successful lifestyle. The core category, 'disclosing of self-esteem' incorporated the relationship between and among all categories and explained the process. The findings indicate that self-leading leisure activities helped to their own health and developed their social activities. Therefore, we would consider in developing health promotion program about favoring leisure activities factors for the middle age office worker.

The blooming of social media has simulated interest in sentiment analysis. Sentiment analysis aims to determine from a specific piece of content the overall attitude of its author in relation to a specific item, product, brand, or service. In sentiment analysis, the focus is on the subjective sentences. Hence, in order to discover and extract the subjective information from a given text, researchers have applied various methods in computational linguistics, natural language processing, and text analysis. The aim of this paper is to provide an in-depth up-to-date study of the sentiment analysis algorithms in order to familiarize with other works done in the subject. The paper focuses on the main tasks and applications of sentiment analysis. State-of-the-art algorithms, methodologies and techniques have been categorized and summarized to facilitate future research in this field.

Literature indicates an increased risk of suicide among women who have had cosmetic breast implants. An explanatory model for this association has not been established. Some studies conclude that women with cosmetic breast implants demonstrate some characteristics that are associated with increased suicide risk while others support that the breast augmentation protects from suicide. A systematic review including data collection from January 1961 up to February 2014 was conducted. The results were incorporated to pre-existing suicide risk models of the general population. A modified suicide risk model was created for the female cosmetic augmentation mammaplasty candidate. A 2-3 times increased suicide risk among women that undergo cosmetic breast augmentation has been identified. Breast augmentation patients show some characteristics that are associated with increased suicide risk. The majority of women reported high postoperative satisfaction. Recent research indicates that the Autoimmune syndrome induced by adjuvants and fibromyalgia syndrome are associated with silicone implantation. A thorough surgical, medical and psycho-social (psychiatric, family, reproductive, and occupational) history should be included in the preoperative assessment of women seeking to undergo cosmetic breast augmentation. Breast augmentation surgery can stimulate a systematic stress response and increase the risk of suicide. Each risk factor of suicide has poor predictive value when considered independently and can result in prediction errors. A clinical management model has been proposed considering the overlapping risk factors of women that undergo cosmetic breast augmentation with suicide.

Purpose: The coronavirus disease 2019 (COVID-19) vaccine is the key to getting out of the pandemic. However, acceptance of the vaccine has been affected by false information and rumors, which have kept people from getting the shot since it was rolled out. Materials and Methods: This study aimed to investigate the various misconceptions surfaced about the COVID-19 vaccines in Africa. We performed an online survey using an anonymous questionnaire to reach out to African respondents by social media and all possible online platforms such as Facebook, WhatsApp, Instagram, Twitter, YouTube, and so forth. The web-based questionnaires about the myths surrounding the vaccines were extracted from nonscientific information, unproven statements, social media posts, news reports, and people's concerns about the safety of the COVID-19 vaccines. Participants indicated their level of agreement with each statement. Results: A total of 2,500 people responded to the online survey in Africa. The two common myths that respondents agreed with were that "since vaccines for COVID-19 have been developed, we can make vaccines for the common cold, human immunodeficiency viruses, and other diseases" (n=892, 35.7%) and that "researchers rushed the development of the COVID-19 vaccines; therefore, it is not very effective, safe and cannot be trusted" (n=595, 23.8%). The range of respondents who neither agreed nor disagreed with these myths was 12.4%-33.0%. The majority (1,931, 77.2%) indicated disagreement with the statement "after getting the COVID-19 vaccine, one can stop wearing a mask as well as taking safety precautions." Conclusion: Myths surrounding the COVID-19 vaccines have impact on acceptance. Exploring them helps public health authorities in Africa dispel them and provide accurate information to promote vaccination campaigns, education, and acceptance.

Globally, diabetic retinopathy (DR) is one of the leading causes of blindness, that diminishes quality of life. This study aimed to describe the prevalence of DR, and its associated risk factors. This cross-sectional study was carried out among 478 diabetic patients in a referral center in Fars province, Iran. The mean${\pm}$standard deviation age of the participants was $56.64{\pm}12.45$ years old and DR prevalence was 32.8%. In multivariable analysis, lower education levels (adjusted odds ratio [aOR], 0.43; 95% confidence interval [CI], 0.24 to 0.76), being overweight (aOR, 1.70; 95% CI, 1.02 to 2.83) or obese (aOR, 1.88; 95% CI, 1.09 to 3.26), diabetes duration of 10 to 20 years (aOR, 2.35; 95% CI, 1.48 to 3.73) and over 20 years (aOR, 5.63; 95% CI, 2.97 to 10.68), receiving insulin (aOR, 1.99; 95% CI, 1.27 to 3.10), and having chronic diseases (aOR, 1.71; 95% CI, 1.02 to 2.85) were significantly associated with DR. In conclusion, longer diabetes duration and obesity or having chronic diseases are strongly associated with DR suggesting that control of these risk factors may reduce both the prevalence and impact of retinopathy in Iran.

Purpose: The purpose of this study is to analyze the research trends of domestic research ethics and to draw implications for the limitations of existing research and future development directions through this. Research design, data and methodology: To this end, this study first examined the concept of research ethics and research area to derive an analysis frame. In addition, 72 academic papers published in domestic journals from 2000 to November 2020 were analyzed according to the research period, research area, research subject, research field, research method, and the nature of the journal. Results: As a result of the analysis, it is judged that social interest in research ethics led to academic interest after the 2005 Hwang Woo-seok incident. These characteristics show that the interest of academia is changing and increasing significantly when issues related to research ethics are raised socially. Of the 72 papers to be analyzed, 29 (40.3%) conceptual and theoretical studies on research ethics and 43 (59.7%) studies on practical measures were surveyed. Conclusions: In the case of published journals on research ethics, the proportion of publications in humanities and social sciences and pedagogical journals was high, and in research methods, literature and theoretical studies were the highest.

Breast cancer risk assessment has developed during years and evaluation of genetic factor affecting risk of breast cancer is an important component of this risk assessment. The aim of this meta-analysis was to investigate the role of XRCC1 polymorphisms (Arg194Trp, Arg280His and Arg399Gln) in risk of breast cancer among different population and categories of menopausal status.PubMed, Medline, Web of Science, and PubMed Central were systematically searched to identify studies evaluating association between breast cancer and XRCC1 gene polymorphisms (Arg194Trp, Arg280His and Arg399Gln). Two authors independently extracted required information. Odds Ratios were pooled for four genetic inheritance models using both fixed and the DerSimonian and Laird random-effect models. Egger's test and contour-enhanced funnel plot was used to evaluate publication bias and small study effect. Additional subgroup analysis was performed for menopausal status, ethnicity, and source of controls. After evaluation and applying inclusion criteria on extracted studies, fifty three studies were included in this meta-analysis. For polymorphisms of Arg194Trp and Arg280His, no significant association was observed in all genetic models. Arg194Trp had a protective effect in post-menopausal status only in homozygote model (OR=0.57 [0.37-0.88]). Arg399Gln showed significant association with breast cancer in homozygote (OR=1.21 [1.10-1.34]), dominant (OR=1.09 [1.03-1.15]) and recessive (OR=1.21 [1.09- 1.35]) genetic models. Arg399Gln was associated with higher risk in post-menopausal status for homozygote and heterozygote models. Our findings suggest that XRCC1 gene polymorphisms modify breast cancer risk in different populations and different categories of menopausal status.

The paper critically examines resource mobilization theories, frame theory, and new social movement theories, and proposes studies on the spatiality of the social movements as one potential to mitigate the limitation in these theories. The resource mobilization theories and the frame theory, the strategy-oriented approaches, lack contextual understandings of the origin of social movements. While new social movement theories provide macro-scale analysis and the structural explanations of the origins of social movements, they have covered limited geographical areas. The spatiality of social movements promotes deep understandings of local differences, and contexts in and through which grievances are constructed and collective actions are organized. Physical structures and symbolic representations of places are often created and utilized as social movement strategies. The spatiality of social movements can be a useful conceptual tool to explain the diversity and the dynamics of social movements.
