Background: It is estimated that about 13 million artisanal and small-scale miners carry out their activities under harsh, precarious, unfriendly, and risky conditions. Yet, our understanding of the extent to which these workers use personal protective equipment (PPE) and navigate through the various risks and hazards they face is still limited. This article has two main objectives. First, it explores the extent of usage of PPE among artisanal and small-scale miners for the prevention of hazards and risks. Second, it examines the coping strategies used by these miners as a response to experiences of occupational injuries and risks Methods: A cross-sectional survey of small-scale miners was conducted in six communities across three districts in Ghana, West Africa. The mixed methods approach was adopted. A total of 148 small-scale miners participated in the study. Six focus group discussions (FGDs) were held across the six communities. The data were analysed using descriptive statistics. Chi-square tests were used to analyse the relationship between some socio-demographic characteristics (sex, age, and educational background) and the usage of PPE. Open-ended questions and responses from FGDs were analysed based on the content and verbatim quotations from miners. Results: Findings suggest that 78% of the miners interviewed do not use the appropriate PPE citing reasons such as cost, and their personal discomfort associated with use of PPE. There was no significant relationship between socio-demographic characteristics (i.e., sex, age, education and major mining activity) and the usage of PPE. The study further revealed four main coping strategies used by miners to handle the risks. These are rest, taking unprescribed medication and hard drugs, registration with health insurance scheme and savings and investments. Conclusion: This study shows that very few artisanal miners use PPE despite the significant hazards and risks to which they are exposed. The study recommends to the government to put in place measures to ensure that miners adhere to health and safety regulations before undertaking mining activities. This means that health and safety plans and use of PPE should be linked to the license acquisition process for miners.

The purpose of this study was to examine the workday leisure time of dual-income fathers and mothers with preschool children. Data were gathered from the Statistics Korea Life Time Surveys from 2004(y1) and 2019(y2) (n=2,697). Life time was composed of three types(inevitable time, compulsory time, and leisure time) and leisure time was categorized into 11 activities(voluntarism, participation, social relationships, religion, rituals, culture and tourism, sports, game and play, media, rest, and others) to investigate gender differences and time effects. The major results were as follows: First, both working fathers and mothers with preschool children spent less inevitable time, more compulsory time, and less leisure time, than other adult group. Second, fathers spent more time on 10 leisure activities except religion in y1, and on all activities than mothers in y2. In y2, less time on three activities(social relationships, rituals, and media) for both fathers and mothers, less time on religion for mothers only, more time on two activities(participation, game and play) for both groups were spent than y1. Third, in the regression analysis of fathers' and mothers' leisure time on three leisure activities(sports, game and play, and media) with a distinct pattern from leisure time for adult group between y1 and y2, socioeconomic variables and lifetime variables showed different effects by gender and waves. Based on the results, family policy and programs to improve the work-life balances of working fathers and mothers discussed.

This study is expected to be of significance in that it attempted to examine the personal information protection awareness of college students and the state of their personal information protection as prospective information processors and private information owners to boost their will to put private information protection in practice. As a result of making an analysis, the most common average time that the students spent in doing every online activity on weekdays was fewer than two or three hours, and the most dominant activities that they did over the Internet were for entertainment or hobbies. As for awareness of the nature of the Internet, they looked upon it as a quite open public space. Regarding the state of private information protection, they thought that changing passwords on a regular basis would be beneficial to personal information protection, and many thought that it's needed to withdraw from or shut down web sites that weren't used for a long time. In terms of actual practice, however, they didn't change their e-mail passwords regularly on the grounds that it's a hassle, and even the students who had experience of personal information leakage didn't report it or didn't ask for counsel on the grounds that they didn't want to be bothered as well. The majority of the students weren't cognizant of how to report or seek counsel. In the future, personal information protection should be educated on a continual basis as part of curriculum to raise awareness of it among students and boost their will to practice it with a sense of responsibility in an effort to prevent the occurrence of collateral damages triggered by personal information leakage.

The purpose of this article is to study on the Correlative linkage between the cosmic principle of birth-growth and contraction-recess and the Non action Tao. The split time between birth-growth and contraction-recess is the conflict between the Prior Time and Posterior Time as the Great Renewal. The cycle of this Chaotic Renewals is the cycle of a cosmic circulation as 129,600 years. In relation to the correlative linkage of function, Jeong-san Sangje governs all the beings of the universe by means of the cosmic principle birth-growth and contraction-recess. Also Jeong-san Sangje, using the Non action Tao governing all the beings of the universe and let them exist as the original selves. Thus, the two necessities are mutual interdependent and mutual complementary. In relation to the correlative linkage of substance, Jeong-san Sangje is included in the cosmic life which forms of all the existences. That is personal God of Jeong-san Sangje that is a part of the cosmic life. So that Jeong-san Sangje is included in the cosmic life, the basis of all the cosmic affairs. He is also subordinate to the cosmic principle but he simultaneously governs it. Jeong-san Sangje is trans-versal mediator between the cosmic principle and the cosmic life of Non action Tao, since it is the origin of his mind. To understand the nature of Jeong-san Sangje who becomes one with the cosmic life, the old causal way of thinking which inquires the timely order and seeks for causes and effects should be abandoned. The new way of thinking is thus different from the old one. The core of cosmic life is abstracted as the essence-energy and god-blood. This structure is similar to the cosmic principle of birth-growth and contraction-recess. The death is a kind of event caused by the depletion of the essence, and all beings could altered into the god. It also would be returned to the natural birth place of the cosmos, as it were, that can be called the 'Return to the Origin'. As the cosmos goes to the new epoch, humans have been living together with the cosmic principle. Now we can expect the Posterior Time to open to humans as cosmic life of Non action Tao.

Disabled elderly faced with disability and the aged problems at the same time. So, this research creates two research questions and examines. First research question is how nine dimensions of daily life satisfaction according to gender difference. Second research question is how the factor of daily life satisfaction by gender difference. The data is sixty-five disabled elderly, 386 among Panel Survey of Employment for the Disabled(PSED, 2008). The methods of analysis for identifying research questions is t-test and multiple linear regression. The result of analysis on first research question, the gender difference six dimensions among nine dimensions of daily life satisfaction come out statistically significant. And The result of analysis on second research question, come out statistically significant, too. Socioeconomic status: the lower class, physical condition: bad health, chronic disease is or not, family and other people's social supports, disability: serious turn out to be factors in common. It has been suggested social policies from the results of studies that the provision of health support policy and program, enlarge assistance on daily life, support system on serious disabled elderly. On the other hand, analysis showed that distinctive factors between disabled elderly man and woman was age and education level. In other words, disabled elderly woman come out into the open that the more grow old, the less daily life satisfaction low, while disabled elderly man appeared higher daily life satisfaction in case of junior and senior high school graduate than uneducated.

The purpose of this study was to examine the impact of climacteric women's attitude to developmental phenomena and their menopausal symptoms on their meaning of life in an attempt to provide some information on the improvement of climacteric women's quality of life. The subjects in this study were 313 women who resided in different regions involving a large city D and another city C. They were aged between 40 and 60 and were going through their menopause. They were aged between 40 and 60 and were going through their menopause. The subjects were selected by convenient sampling, which was one of nonprobability sampling methods. The collected data were analyzed by the statistical package SPSS. The major findings of the study were as follows: First, the climacteric women didn't take a positive attitude toward developmental phenomena. They occasionally suffered severe menopausal symptoms, and they didn't find a great meaning in their life. Second, the climacteric women found a more meaning in their life when they took a more positive attitude to developmental phenomena, and those who underwent severer menopausal symptoms found a less meaning in their life. Third, the climacteric women's meaning of life was under the influence of their attitude toward developmental phenomena and menopausal symptoms. Specifically, their attitude to menopause and mental symptoms had a large impact on that. Given the findings of the study, social welfare intervention should be provided for climacteric women to promote their physical health related to menopausal symptoms and psychological health related to attitude toward developmental phenomena to find a more meaning in their life. Besides, local welfare centers should be open to climacteric women as one of governmental policies so that they could lead a healthy life. Education should be provided for them to be ready for their own menopause, and social welfare counseling service should be offered from diverse angles

This study examines the conception of the self using indigenous, cultural and psychological analysis. The self is viewed from four aspects: (1) conception of the self as an entity (the self in general, the self as an unique entity and the self when alone), (2) conception of self in the context of family (the self when with mother, father, children and spouse), (3) the self with the context of close and working relationships (the self when with friends, teachers, work superior and work subordinate), and (4) the self in context of the larger society (the self when with strangers and foreigners). A total of 1,465 respondents (623 elementary, middle, high and university students and their parents = 842) completed an open-ended questionnaire developed by the present authors. The results reveal two patterns of results. First, the conception of self in Korea is influence by one's role. Second, the conception of self in influenced by relationship and context and there is an emphasis on the flexibility and adjustment of the self to relationship and context. Implications of the conception of the self in context of relationships, roles, and contexts are discussed, along with the importance of indigenous, cultural and psychological analysis.

The environmental stress that plants are most susceptible to is water stress. Abscisic acid (ABA) is a plant hormone synthesized by plants to counteract environmental stress. The role of stomata in plants is to allow the synthesis of sucrose by absorbing CO₂, which greatly affects photosynthetic activity. In addition, stomata are pathways for transpiration, which releases H₂O and help establish a water potential gradient that allows plant roots to continuously absorb water and inorganic substances from the soil. Plants have a mechanism to minimize water loss by closing their stomata when exposed to water-stressed environments. The most well-studied hypothesis concerning the mechanism of stomatal closure is the response to water stress. When a plant receives sufficient water, its stomata open during the day and close at night due to its circadian rhythm. In addition, stomatal closure occurs when the concentration of CO₂ in the intercellular space increases. However, the mechanism of stomatal closure due to circadian rhythm and increased CO₂ concentration in the intercellular space is not well understood. When plants undergo water stress, the increased concentration of ABA in the guard cell cytoplasm induces an increase in Ca²⁺ concentration, resulting in cytoplasmic depolarization. As a result, the outward K⁺-channel of the tonoplast and the slow-type anion channels SLAC1 and SLAH3 are activated, releasing K⁺, Cl^-, and malate^2-, causing the stomata to close. Therefore, in this paper, the mechanism of stomatal closure caused by water stress was investigated.

Background: Long-term oxygen therapy (LTOT) improves the survival of patients with hypoxemia due to chronic respiratory diseases. The clinical outcomes of LTOT are strongly associated with patient adherence. To improve the adherence of patients, physicians have focused on the efficacy of LTOT. However, poor adherence may stem from patients' perceptions of LTOT. Herein we evaluated patients' perceptions of LTOT affecting adherence. Methods: We conducted a cross-sectional survey study using descriptive, open, and closed-ended questionnaire. Patients using oxygen therapy (OT) or requiring it but avoiding OT responded to the questionnaires at three university hospitals. Results: Seventy-nine patients responded to the questionnaires. The number of patients using home and portable OT was 69 (93%) and 37 (46.3%), respectively. Patients with good adherence were 22 (30.1%). Among patients with good adherence, 90.9% used oxygen according to physicians' prescriptions whereas only 37.3% of those with poor adherence followed physicians' prescriptions (p<0.01). The reasons for avoiding using home OT were fear of permanent use (50%), unwanted attention (40%), and lack of symptoms (40%). They avoided portable OT because of unwanted attention (39%), heaviness (31.7%), and lack of symptoms (21.6%). Conclusion: Patients on LTOT had the perception of the misunderstanding the effects of OT and of psychosocial barriers to initiate or use LTOT. Considering these findings, health professionals need to provide effective education on the purpose of LTOT to improve patient adherence to OT and provide sufficient support for the management of psychosocial barriers in patients using LTOT.
