Background Gynecomastia is a common condition that can cause severe emotional and physical distress in both young and older men. Patients in whom symptomatic recalcitrant gynecomastia persists for a long time are potential candidates for surgery. Methods From January 2014 to January 2016, 15 patients underwent correction of gynecomastia through a single 3-mm incision at our institution. Only patients with true gynecomastia underwent surgery with this new technique. Through the small incision, sharp dissection was performed in a clockwise and counterclockwise direction describing two half-circles. Health-related quality of life and aesthetic outcomes were evaluated using a modified version of the Breast Evaluation Questionnaire (BEQ). Results The patients' average age was 23.5 years (range, 18-28 years), and their average body mass index was $23.2kg/m^2$ (range, $19.2-25.3kg/m^2$). One case was unilateral and 14 cases were bilateral. The weight of glandular tissue resected from each breast ranged from 80 to 170 g. No excess skin was excised. Bleeding was minimal. The mean operating time was 25 minutes (range, 21-40 minutes). No complications were recorded. All lesions were histologically benign. The patients' average score was 3.5 (on a 5-point Likert scale) in all domains of the BEQ for themselves and their partners. Conclusions In this study, we demonstrated the safety and reliability of a new technique that allows mastectomy through an imperceptible 3-mm incision. We obtained high patient satisfaction scores using our surgical technique, and patients reported considerable improvement in their social, physical, and psychological well-being after surgery.

High forecast accuracy is required as social issues on particulate matter increase. Therefore, many attempts are being made using machine learning to increase the accuracy of particulate matter prediction. However, due to problems with the distribution of imbalance in the concentration and various characteristics of particulate matter, the learning of prediction models is not well done. In this paper, to solve these problems, a binary classification model was proposed to predict the concentration of particulate matter needed for prediction by dividing it into two classes based on the value of 80㎍/㎥. Four classification algorithms were utilized for the binary classification of PM10. Classification algorithms used logistic regression, decision tree, SVM, and MLP. As a result of performance evaluation through confusion matrix, the MLP model showed the highest binary classification performance with 89.98% accuracy among the four models.

This study is to explain the nature of transnational activities being involved in by Filipina intermarriage migrants in Korea by examining the institutional backgrounds of market, society and the state. The increasing number of Filipina intermarriage with Korean coincides with the advance of liberal market economy, which governs internal and bilateral interactions between and among the three institutions in both countries. While existing various reasons for engaging in intermarriage, a significant number of Filipina wives in Korea ventured into it with uncertain expectations that they might earn better lives and could support their families. Such hopes usually turn out in vain when they meet the real lives in Korea. It is mainly because their spouses in Korea would rather be those who left behind in the marriage market due to their lack of competitiveness. Filipina wives are also suffering from social isolation caused by language and other barriers such as family relations or rural life they might settle in. Their transnational activities usually tend to be their effort to breakthrough their unexpected condition of difficult lives in Korea. They usually make use of transnational sort of community activities to cultivate chances to engage in bread earning activity. Migrant's transnational activity has a great impact on sociocultural changes in the country of origin and of arrival. Transnational activity provides migrants with economic opportunities, and uplifts self-esteem as well. Intermarriage couples, especially with Southeast Asian wives, and their offsprings show a tendency of downward assimilation to Korean society. Korean state policy toward them should not simply apply undiscriminated assimilation theory, but take into account their possible strength of transnational identity with which they could find a means to integrate themselves successfully into the mainstream Korean society.

Japanese imperialism initiated the Sino-Japanese War in 1937 and promulgated the Total National Mobilization Act in 1938, establishing a wartime total mobilization system. In the beginning of the wartime general mobilization system, Japanese colonialism focused on women's labor force and mobilized women both domestically and abroad. Women were forcibly mobilized to the Labor Patriotism Unit and Jeongshindae(Korean Women Labor Corps). Women had to take the place of home work as well as the work of men who had already been mobilized, and at the same time faced a poor situation of being forced to mobilize for war. The mobilization of Jeongshindae took place in various forms, such as recruitment, voluntary support by government offices, propaganda through schools or groups, job fraud, coercion or threats. Jeongshindae which was a representative victim of the forced mobilization of women during the Japanese colonial period, was individually litigated and remains an unresolved problem. In order to uncover the reality of the forced mobilization of women during the wartime general mobilization system, continuous research and social education through related organizations are required.

Objectives: This study was conducted to investigate the emotional characteristics of adults who complained of fatigue using the Core Seven Emotion Inventory-Short Form (CSEI-s) followed by correlation analysis with the Chalder fatigue scale (CFQ) and Psychosocial Well-being Index-Short form (PWI-SF). Methods: In this study, the medical records of 45 participants who complained of fatigue and completed the CSEI-s, CFQ, and PWI-SF were evaluated. Records of a total of 45 adults were analyzed using SPSS (Statistical Package for the Social Sciences, Version 25.0). Frequency Analysis, Descriptive Analysis, Independent t-test, One Way ANOVA, and Correlation analysis were used for data analysis. Results: 1. According to the educational status of the participants, Thought (思) was identified to be significantly higher in below college graduate than in graduate school and above. 2. As the period of complaining of fatigue increased, a significant difference was observed in Depression (憂) and Fright (驚). 3. According to the degree of fatigue, there was a significant difference in Depression (憂) and Fright (驚), and especially Depression (憂) was higher in the middle fatigue group than in the low fatigue group. 4. PWI-SF, Anger (怒), Depression (憂), and Sorrow (悲) showed a positive correlation with CFQ scores. Conclusions: The results suggest that CSEI-s can be used to measure the psychological symptoms of a patient with fatigue.

Rider jackets were once reserved for military uniforms but have become an important styling item in recent fashion trends. The design characteristics of the rider jacket are rooted in symbolism, and the image associated with a rider jacket is in line with the challenging of authority and being a member of the rebellious youth subculture. Usually, young people with anti-social tendencies wore jackets, and some styles were used as a medium to express their emotional homogeneity, and they received favorable responses as the items represented them. The design characteristics of a rider jacket can be largely divided into resistance against the older generation, violence, challenging cultural norms, sexuality, and resistance, as well as embodying violent characteristics, including strength, courage. and male chauvinism. The reason for the development of these challenging characteristics are disparagement and anger of the lower class, who were excluded from mainstream society. Rider jackets can be viewed negatively due to the kind of message it is conveying against mainstream society. Among the sexual features were leather pants, short-length leather rider jackets, glossy metal accessories, and belt buckles, which also highlighted gay and decadent images that came to be associated with the jackets. The drapery created various kinds of wrinkles according to the way of dressing, and it had beautiful expressiveness while serving to express the body more beautifully. Drapery can be classified according to the aesthetic characteristics or expression techniques, and if the type of drapery is classified according to the morphological characteristics, it can be classified into variable and fixed structures, depending on whether the part to which the drapery is applied is fluid or not. In other words, it depends on the dressing method or the intention, and if the drapery technique is directly applied to the garment or is attached to the form. This fashion design proposal may have the greatest significance in that it sought to propose a new style incorporating a drapery technique with a strong feminine image to a rider jacket, which traditionally was associated with a masculine image.

Cyber threats are also increasing with recent social changes and the development of ICT technology. Malicious codes used in cyber threats are becoming more advanced and intelligent, such as analysis environment avoidance technology, concealment, and fileless distribution, to make analysis difficult. Machine learning technology is being used to effectively analyze these malicious codes, but a lot of effort is needed to increase the accuracy of classification. In this paper, we propose a malicious code detection technology based on API call interval characteristics to improve the classification performance of machine learning. The proposed technology uses API call characteristics for each section and entropy of binary to separate characteristic factors into sections based on the extraction malicious code and API call order of normal binary. It was verified that malicious code can be well analyzed using the support vector machine (SVM) algorithm for the extracted characteristic factors.

Legislative approaches to regulating the digital sex industry are increasingly being debated at the international and national levels. There is a trend showing an increased interest in the decriminalization of sex work. At the same time, in many countries, activities related to digital prostitution remain criminalized. In this regard, it is important to analyze the international legal experience of the criminalization and decriminalization of digital prostitution, as well as to pay attention to the key problematic issues that arise during the criminalization and decriminalization of such an issue. The object of the study is the international experience of criminalization and decriminalization of digital prostitution. The subject of the study is social relations that arise, change, and cease during the criminalization and decriminalization of digital prostitution. The research methodology consists of such methods as philosophical, logical, special-legal, system analysis methods, and formal-dogmatic methods. Research results. As a result of the study of the international legal experience of criminalization and decriminalization of digital prostitution, it was concluded that the criminalization and/or decriminalization of digital prostitution is treated differently in different countries. Workers in this industry advocate decriminalization, not legalization, because decriminalization puts power directly in the hands of sex workers and creates no legal barriers. Countries that have decriminalized digital prostitution believe that sex work is real work and should be treated respectfully, and banning resources such as OnlyFans is not in favor of such workers. Regarding positions on the criminalization of prostitution, countries use different models of such criminalization, including the model of legalization of digital prostitution, which, on the one hand, allows prostitution, but establishes criminal liability for deviations from the rules established by the state.

Background: Healthcare workers perform an emotionally exhausting daily work activity, making them prone to occupational hazards, namely psychosocial ones. This study aims to assess the impact of psychosocial risk factors on healthcare workers' mental health. Methods: A cross-sectional study was developed between May and June of 2021 with 479 healthcare workers from Portuguese hospitals. The Depression, Anxiety and Stress Scale was used to assess mental health, and psychosocial risks were assessed through the Health and Work Survey - INSAT. Statistical analysis was performed to identify the psychosocial risk factors related to anxiety, depression, and stress. Subsequently, a multiple linear regression was performed to identify the models that better explained psychosocial risk factors' relationship with anxiety, depression, and stress. Results: Data showed a strong exposure to psychosocial risks. Work pace and intensity, work relationships, and emotional demands stood out with higher global average percentages for yes answers to "exposure and discomfort." The analysis of the b values and p-values from the multiple linear regression shows that some cross-sectional psychosocial risks are predictors of anxiety and stress dimensions, and other psychosocial risks differ in the two mental health dimensions. However, it is important to highlight that healthcare workers still showed great joy and pleasure in performing their work activities. Conclusion: Support network development in the work environment is needed to prevent healthcare workers' emotional stress and promote their psychological well-being. Therefore, new research is essential to understand the psychosocial risks that affect healthcare workers and assess the less visible effects of work-health relationships.
