Coronavirus disease 2019 (COVID-19), which is a newly emerging infectious disease worldwide, can be categorized as an occupational disease, because employees, particularly in the healthcare system, can be infected at the workplace. As of December 15, 2020, we summarized the occupational safety and health practices in selected countries on the recognition of COVID-19 as one of the occupational risks. The situation has differed among countries, including the recognition status and whether a specific regulation existed. International organizations, namely the International Labour Organization, World Health Organization, and European Union, should plan and conduct studies on the work-relatedness of COVID-19, propose criteria for recognition, and add the infection to the occupational disease list to provide a basis for specific country regulations. Stakeholders should also act to adjust country-level legislation.

Purpose: This study is descriptive research that confirms breakfast eating habit of woman's college students and related factors. Methods: This investigation took place in August 2010 and was participated 142 students of one woman's college which located in a large city. The contents of the questionnaire consists of general trait, diet trait, life patterns and health states. Results: According to the results of uni-variate analysis, the significant variables of breakfast eating habit are: Recognition of importance of breakfast, spare time before attendance, her parents's breakfast eating habit, times of snack, times of eating out and index of food life style. But, according to the results of multi-variate analysis, the number of the significant variables became narrow and they were: Recognition of importance of breakfast, spare time before attendance and her father's breakfast eating habit. Conclusion: Finally, it can be said that the breakfast eating habit of woman's college student is related to recognition of importance of breakfast, spare time before attendance and her father's breakfast habit strongly. It is necessary to emphasis on the recognition of the importance of breakfast and concerns of parents for breakfast eating habit to improve the regularity of breakfast eating habit for woman's college students' health.

Objectives: In this paper, we propose the ethical education direction by analyzing the personal information recognition and practice of music therapists. Methods: For the analyses, we selected 60 music therapists who answered a questionnaire from members of K Music Therapy Association, and analyzed task recognition and practice ask performance using IPA method. Results: In the IPA table, the areas of high recognition and practice (1) are the areas of personal information protection information management. In the IPA table, the areas of low awareness and high practice (2) are areas of privacy communication for those who have completed ethics education. In the IPA table, the areas of low awareness and low practice (3) are areas of privacy communication when ethics education is not completed. In the IPA table, areas of high awareness and low levels of practice (4) are areas of privacy protection. Conclusions: Continuing education should be provided to improve the curriculum on the protection of personal information for music therapists, thereby raising the awareness and practice of privacy.

A new method is proposed based on a hidden Markov model (HMM) to estimate and analyze battery states of health. Battery system health states are defined according to the relationship between internal resistance and lifetime of cells. The source data (terminal voltages and currents) can be obtained from vehicular battery models. A characteristic value extraction method is proposed for HMM. A recognition framework and testing datasets are built to test the estimation rates of different states. Test results show that the estimation rates achieved based on this method are above 90% under single conditions. The method achieves the same results under hybrid conditions. We can also use the HMMs that correspond to hybrid conditions to estimate the states under a single condition. Therefore, this method can achieve the purpose of the study in estimating battery life states. Only voltage and current are used in this method, thereby establishing its simplicity compared with other methods. The batteries can also be tested online, and the method can be used for online prediction.

We present a speech processing strategy incorporating instantaneous frequency (IF) encoding for the enhancement of melody recognition performance of cochlear implants. For the IF extraction from incoming sound, we propose the use of a Teager energy operator (TEO), which is advantageous for its lower computational load. From time-frequency analysis, we verified that the TEO-based method provides proper IF encoding of input sound, which is crucial for melody recognition. Similar benefit could be obtained also from the use of a Hilbert transform (HT), but much higher computational cost was required. The melody recognition performance of the proposed speech processing strategy was compared with those of a conventional strategy using envelope extraction, and the HT-based IF encoding. Hearing tests on normal subjects were performed using acoustic simulation and a musical contour identification task. Insignificant difference in melody recognition performance was observed between the TEO-based and HT-based IF encodings, and both were superior to the conventional strategy. However, the TEO-based strategy was advantageous considering that it was approximately 35% faster than the HT-based strategy.

Purpose: The purpose of this study was to explore the influence in a planned pregnancy of alcohol related family variables, knowledge and recognition of the effects of alcohol use during pregnancy on actual alcohol use during pregnancy. Methods: The participants were 284 women who had experienced a pregnancy at some time in their lives. The data were collected from December 2011 to January 2012 and the method of data collection was self-report questionnaires. The instruments for this study were AUDIT-K, Knowledge of alcohol use during pregnancy, and Recognition of alcohol use during pregnancy. Results: There were higher incidences of alcohol use during pregnancy when alcohol consumption was a problem, when there was a family member with an alcohol problem, or after having had an artificial abortion. There was no correlation in alcohol use during pregnancy with knowledge, but a correlation with recognition was found. Conclusion: The results of this study suggest that the main factor in alcohol use during pregnancy is recognition of the effects of alcohol use during pregnancy.

Objectives: The purpose of this study was to provide basic data for suggesting the realistic plan for the prevention of induced abortion. We performed an analysis of a recognition and actual conditions of the induced abortion according to the marital status. Methods: Participants were 681 persons of 20 years of age or older who lived in 7 cities and provinces. The data was collected with a structured questionnaire. For data analysis, Chi-square test, t-test and stepwise discriminant analysis were utilized. Results: The results were as follows. When degrees of recognition were analyzed according to the marital status, married were found to have higher levels of recognition of induced abortion than unmarried. From comparison of the recognition, there were significant differences between married and unmarried in terms of the recognition of the law, premarital sex, sex consciousness, intention of induced abortion, knowledge of contraception. Conclusion: The above results showed that marital status was strongly related to the recognition of induced abortion. And measures for preventing the induced abortion, specially about 20 percents of risky unmarried, should be focused.
