Explosion and fire cause about 30 reported industrial major accidents a year by ignition source which discharge of electrostatic generated to flammable gas, vapor, dust and mixtures. It brings economically and humanly very large loss that accident was caused by fire and explosion from electrostatic discharge. Thus, it is very important that electrostatic discharge energy is to be control below not to be igniting flammable mixtures. There are two kinds of analysis model for electrostatic discharge, human body model and machine model. Human body model is available the parameter of human's electrical equivalent that capacitance is 100 pF, resistance is $1.5k{\Omega}$. To simulate and visualize the electrostatic discharge from human body need a very expensive and high voltage simulator. In this paper, we measured the value of capacitance and resistance concerned with test materials and sizing of specimen and the value of charged voltage concerned with test specimen and distance to develop an electrostatic charge/discharge simulating tool for teaching with which concerned industrial employee and students. The result of experiments, we conformed that the minimum ignition energy of methane-oxygen mixtures meets well the equation $W=1/2CV^2$, and found out that the insulating material and sizing of equivalent value having human body mode are the poly ethylene of 200 mm and 300 mm of diameter. Developed electrostatic charge/discharge simulating tool has many merits; simple mechanism, low cost, no need of electric power and so on.

Objective : A pilot project entitled '50s mental health screening project' was conducted in Seoul. As a part of this project, we conducted surveys to obtain the opinions of psychiatrists regarding mental health screenings. Methods : A questionnaire was mailed to members registered with the Korean Neuropsychiatric Association, which enquired about the '50s mental health screening project'. Results: A majority (90.9%) of the subjects agreed on the purpose and implementation of the project. However, there were fewer individuals that actually showed the intent to participate (65.8%). The mean age of the group with the intention to participate was higher compared to the group with no intention to participate. The factors that negatively affected the intent to participate included prejudice and discrimination against psychiatry (3.795), low health insurance reimbursement (3.784), and inconvenience of reporting to public health centers (3.664). The most appropriate method that scored the highest for screening mental health was face-to-face consultation with a psychiatrist (3.889). Most of the participants agreed on the method of a self-reported survey along with an interview of psychiatrist (84.9%). Conclusion : Subjects were concerned about prejudice and discrimination against psychiatry, low health insurance reimbursement, and inconvenience of reporting to public health centers. These problems need to be supplemented. Face-to-face consultation with a psychiatrist may be considered an appropriate method for future mental health screening.

To investigate male office workers' dietary habits and their perception and intake of health functional foods, 234 male employees were surveyed by questionnaire. The results were categorized into three age groups: under 35 years, 35 and 45 years, and over 45 years. The over 45 years group had significantly better dietary habits than the others (p<0.05). The most common reason for skipping breakfast was lack of time. Frequency of drinking alcohol was higher in the older group, where tiredness after drinking was lower in the younger group. The perception score of health functional foods was highest in the over 45 years group. Perception of health functional foods was more positive as the age of the groups increased (p<0.01). The number of health functional foods consumed, duration of intake, and beneficial health effects were higher in older groups. Although older people are more concerned about health than relatively younger people, they did not necessarily have reduced the amounts of smoking and drinking. Instead, they simply showed higher intakes of health functional foods to prevent and cure disease and improve their health. Therefore, older people need to receive education about their dietary and living habits instead of simply eating health functional foods. It is necessary to provide correct information about health functional foods by nutritional education.

Purpose: This qualitative study utilizing phenomenological methodology aimed to depict parental measles mumps rubella (MMR) vaccine acceptance through the work experiences of health personnel. Materials and Methods: Twenty-two public health workers working as vaccination providers in the three southern border provinces of Thailand were recruited. In-depth, face-to-face, semi-structured interviews were conducted. Data were analyzed using thematic analysis. Results: Four main themes emerged: (1) religious beliefs, (2) personal disagreements, (3) fear and mistrust regarding potential vaccine side effects, and (4) misperceptions about the potential severity of measles. Four subthemes were identified: (1) haram (prohibited), (2) the will of Allah, (3) spousal disagreement, and (4) disagreement from a religious leader. The results of this study indicated that perceived religious prohibition was the most important reason for refusing to vaccinate among Muslim parents. Vaccine-hesitant parents were concerned that the vaccine might contain gelatin derived from pig products. Also, halal certification of the vaccine was required from Muslim parents to ensure that vaccine has been approved for Muslims. Meanwhile, a lack of knowledge and positive attitudes concerning immunizations of vaccine-hesitant parents were also found as predominant reasons for incomplete childhood immunizations in the deep south of Thailand. Conclusion: Health education and engagement by religious leaders to endorse the vaccination and bridge the gap between religious beliefs and vaccine acceptance is needed to overcome this issue. This study findings could be effectively applied to improve vaccination uptake in a Muslim majority context.
