The purpose of this study is to understand when forest fire as a natural phenomenon becomes constructed as social issues in Korea; how the forest fire-related discourses in the editorials reflecting the social perceptions have been changed regarding the principal subject and the measures of the forest fire management; and whether the social perception on the forest fire affects the forest fire policy of the state. From the analysis of a total of 44 editorials related to forest fires from 1988 to 2017. By the using, in the forest fire-related editorials the social perceptions on forest fires are forest fire editorials categories, main keywords, contents of social perception on 'the main subject responsible for forest fire management,' 'forest fire prevention measures,' categorization, frequency analysis and context analysis of words used. It is found that in the first-period forest fire management measures were recognized as a part of the overall forest management. In the second period, the approaches of ecological management emerged on the part of forest fire management. As forest fires were managed as a type of social disaster during the third period, such perceptions were gradually reinforced that the state should protect the people from the forest fire. In the 3rd, 4th, and 5th National Forest Plan, the forest fire management policy of each period was focused in enlightening the general public, protecting forest resources ecosystems, and preventing loss of lives, respectively. As a result of the analysis of social perceptions and comparing them to the forest fire policies through the analysis of editorials on forest fires, it is found that the social perception on the forest fire and forest fire management plan has changed having interconnections.

This study was performed to investigate the food habits, eating behaviors, perception of body shape, statuses of body weight control by BMI (Body Mass Index) of 732 middle school students in Gwangju and Jeonnam. The results of this study were compared among under weight (UW), normal weight (NW), and overweight (OW) groups according to BMI levels. In the OW group, female students had low scores in eating at night only, while male students had low scores in eating at night, eating speed, and food selection. All subjects wanted more height than measured. Only male students in the UW group wanted weight loss, whereas female students in the OW and NW groups did. Higher BMI in female students resulted in more weight difference between measured and wanted. All subjects responded properly themselves in perception of body shape but the OW groups showed a big difference between their present weight and wanted weights. Higher BMI in all students corresponded to more interest in concern and experience of weight management. In the male students, the reason for weight management showed high tendency in being healthy, whereas the female students had high tendency in having a slender figure. Higher BMI in all students corresponded to bigger difference between wanted and perceived body shape. In contrast, lower BMI in all students meant more stress. Greater difference between wanted and measured weight and greater difference between wanted and perceived body shape corresponded to less satisfaction in body shape. In conclusion, compared to the NW and UW groups, the OW group had overeating habits highly linked to stress. Also the OW group didn't have desirable eating behaviors and attitudes because of their greater interest in concern and experience of weight control and stress accumulation, and finally there was difference in food habits and behaviors according to the BMI level. Therefore these results suggest that effective nutritional programs should be developed including correct body image and good dietary habits.

Purpose: The recent proliferation of the aging population, oral health care is closely related to the mental health of the elderly is very important being recognized. Provide basic data for improving the quality of life for the elderly, to determine whether the oral health of the elderly whether oral self-perception of health and any related wish. Methods: Surveys to May 20 from April 15, 2011, subjects were elderly and living in Daejeon and Chungnam 277 people were examined. All the statistics using SPSS 18.0 for the determination of statistical significance, and the significance level was 0.05. Results: 1. Recognized, the most common oral health, self-aware bad the state (46.2%) there was no significant difference in the general characteristics according to self-Oral health status, remaining natural dimensions or the intra-oral prosthetic, there was no significant difference. More teeth, residual phase, in accordance with intra-oral prosthetic mandibular Not all dentures, partial dentures, full dentures net self-perception of oral health status better recognized. 2. According to the type of partial dentures, oral health status self-phase, mixed mandibular removable, fixed, fixed, removable partial dentures in order to recognize that good oral health, self-aware state, showed between them, there was no significant difference. 3. Of variable dimension that has nothing to do with the remaining natural maxillary and mandibular prosthetic maxillary prosthetic mandibular partial dentures, age income, a positive correlation was negatively correlated. The case of the mandible, the mandibular prosthetic mandibular partial denture, maxillary prosthetic, the amount of income were correlated. 4. Intra-oral Prosthetics correlation variables in the maxillary, mandibular prosthesis, the positive correlation between income, age was negatively correlated, if the income of the mandible. Maxillary partial denture has nothing to do with the variable portion of the mandibular denture, age was a negative correlation was found. Conclusion: Satisfaction and how now it is important simply to live as long, but you need to pay attention to the quality of life, sometimes with an aging population and the increase of soybean To buy the loss of teeth causes the typical health problems of the elderly. Elderly people of any relevant oral health and the oral cavity by the state to determine whether to provide the basic data for oral health education was more residual value, intra-oral prosthetics there is no more self-aware, the oral health status is good to recognize that appeared. Strengthen the oral health education to improve the quality of life of the elderly, and is thought to be necessary to increase the number of residual.

The purpose of this study is to investigate the stress and coping level as a result of dysmenorrhea which was experienced by girls. For the collection of data, the girls from the 1st to the 3rd grade in middle school in Seoul were selected through a random sampling technique. The survey was conducted from the 1st. to the 14th of June, 1991 by the use of questionnaires made after a pilot study. The final subjects for analysis were restricted to only those who had experienced me~arche, the number of which totaled 1,131. The stress, coping level, and other variables, were tested and analysed by descriptive statistics (eg, frequency, percentage, mean and standard deviation), t-test, ANOVA and Pearson's correlation coefficients. The obtained results are summarized as follows. 1. The chronological start for menarche was at a mean age of 13.1 The respondents who had experienced menarche numbered $70.9\%$ of the 1st grades and $96.2\%$ of the 2nd grades in middle school, otherwise the starting age for menarche was in the 4th grade in primary school. 2. Their menstrual cycle and period were longer than adult's one. The number of students studied who had experienced dysmenorrhea during their menstrual cycle were 860, and 650 of those revealed that their mothers or sisters had experienced similar problems. 3. The subjects who were late or head left early rather than being absent from school every menstruation cycle were more stressful. The results are thought to show that the girl's perception of dysmenorrhea seems to be more sensitive than adult's one. 4, A significant negative correlation was found between the perception of menstrual flow and strees level. It means that an increase in the stress of dysmenorrhea was associated with decreased menstrual bleeding. The degree of hypochondrical concern assessed by the girls was significantly correlated to stress and coping level. When the girls perceived high stress as a result of dysmenorrhea, they worried about their physical health more. The above results lead us to the suggestion that the starting point of early education with a school program is appropriate for the 4th grade in primary school. Especially if the girls in middle school should be required to give the information about correct knowledge and sufficient self -care management of menstruation monthly, if this could be implemented the loss in school days among the students due to dysmenorrhea would be minimized with more ease.

As a descriptive survey, this study was attempted to get basic data necessary to recognize the factors that disturb the therapeutic atmosphere of hospital wards as perceived by nurses and hospitalized patients, to identify differences between the perceptions of the nurses and of patients. The subjects, 159 patients in Pusan National Hospital and 68 nurses working there were sampled between March 18 and April 13, 1996. The tool used to measure the disturbing factors was an amended form of the one developed by Kim, Mae Ja(1983). The differences between each subject's score for each factor were analyzed using means & SD. and the highest 3 items above the mean score for each factor were collected and compared. The results are described below : 1. Subject's perception of main disturbing factors : patients reported that the main factors were 'loss of role & economic trouble', 'the prognosis of disease', 'the change of daily life' but nurses replied that the main factors were' the prognosis of disease', 'the communication trouble with the medical team & interpersonal relationships'. 'The change of daily life' was not a perceved factor by nurses, but ranked third by the patients. 2. Subject's perception degree of each disturbing factor : (1) among the items related to interpersonal relationship. the patient group reported that the worst disturbance was dur to severely ill patients in the same room' but the nurse group regarded 'greed to monopolize wheelchairs or other supplies' as the worst disturbance. (2) among the items related to physical factors. the patient group regarded 'limitations to wash their body, physical pain and limitations in physical activity' as the worst disturbance, but the nurse group regarded' physical pain', and 'limitations to activity or change of appearance' as the worst disturbance. (3) among the items related to the change of daily activity, the patient group regarded 'the boredom of hospitalization or infavorable diet' as the worst disturbance, but the nurse group regarded 'too much noise or unclean room' as the worst disturbance. (4) among the items related to the communication trouble with medical team, the patient group regarded 'the ignorance of their disease due to poor information. the inability to understand the language of the medical team or the difficulty in seeing physician in time' as the worst disturbance, but the nurse group regarded 'the inability to trust physicians and physician's poor attention to patients' as the worst disturbance.

Objectives: This study was conducted to investigate the experience and perception among adult women regarding weight control and the consumption of weight-control foods or health functional foods based on their body mass index (BMI). Methods: The subjects were 634 adult women from the Chungcheong province, Korea, and data were collected through a self-administered questionnaire from July 2021 through September 2021. The subjects were divided into four groups based on their BMI status: underweight (< 18.5 kg/m², 7.6%), normal weight (18.5 ~ 22.9 kg/m², 53.3%), overweight (23 ~ 24.9 kg/m², 19.7%), and obese (≥ 25 kg/m², 19.4%). Results: Over the past 3 years, almost two-thirds (68.6%) of the adult women had tried weight control measures, despite the fact that a significant proportion of them were normal or underweight. More importantly, 57.6% of subjects reported the consumption of weight-control foods, with a lower proportion in the underweight (35.4%) group compared to the normal (56.2%), overweight (62.4%), and obese (65.0%) groups. The food items used for weight control were mostly salads, chicken breasts, low fat (soy) milk, slimming tea, protein shakes, low-calorie cereals, and energy/protein bars among others. In addition, one-third (31.1%) of the subjects reported the use of health functional foods containing ingredients for fat reduction. A significantly higher proportion of these was from the overweight (36.0%) and obese (38.2%) groups compared to the underweight (20.8%) and normal weight (28.1%) groups. Products containing Garcinia cambogia extract, green tea, or Cissus extract, were popular among users. Subjects who were obese had a poorer perception of their health and body. Most subjects felt the need for correct information regarding weight control, but this number was significantly more in the higher BMI groups. Conclusions: Our results suggest that the use of weight-control foods or health functional foods is popular among adult women, especially those who are obese. Thus, nutrition education courses covering facts about weight control and practice need to be developed and provided based on the BMI status of subjects.

The purpose of this study was to perform a content analysis on 62 domestic and international journals from 1998 to 2017, in order to review research trends in music and people with visual impairments. The framework of the content analysis was based on the year of publication, field of journal, research method, type of research, research subject, participants' age, and factors of impairment. The results showed that both domestic and international journals have rapidly increased in the last 10 years, and have expanded into the fields of education and therapy. In the research method, survey research was conducted much more frequently in domestic journals, while both qualitative and experimental research were employed on a roughly even basis in international journals. With respect to the type and subject of research, music perception and recent trends on the subject of musical interest and aptitude took up the majority of domestic journals, while international journals focused on music intervention, music perception and cognition with musical influences and experiences. The participants in both domestic and international journals were children, adolescents and adults, while the elderly were not observed. In the factors of impairment, research on people with total blindness or low vision were conducted frequently, but those with adventitious vision loss or multiple impairments were rarely performed. This study could be meaningful to suggest the direction of further studies, through the investigation of research trends in music and people with visual impairments.

We developed a new hearing aid telephone which helps the hearing impaired person to improve the listening ability of telephone speech. Recently, the hearing impaired person and the elderly who has hearing loss have been continuously increased and their desire for participating society as a producer has been increased also. So they strong1y want the hearing aid devices which make compensation fortheir handicap. The hearing aid telephone is one of the basic aid devices that helps the hearing impaired to communicate well with other poeple and to acquire easily useful information through the phone. We analyze the hearing ability of the hearing impaired, design the new model of the hearing aid telephone and test the telephone in three fields-electrical, word perception, user test. Our new tolephone has lour band pass filter channels and the center frequencies of these filters are 500, 1000, 2000, 3000Hz which are considered psychoacoustic factors and telephone line characteristics. The hearing impaired can adjust the total gain characteristics of receiving sound to his hearing ability by setting four volumes in the telelphone. This procedure is called fitting which is a very important factor for the hearing impaired to take meaning of speech. The total gain of this telephone is over 20dB from 250Hz to 3200Hz range. From the results of the tests we certify that our new model is better for the hearing impaired to understand the meaning or telephone speech than the old general models. The next step of developing the hearing aid telephone is to study about compressing sidetone and noise, dividing frequency bands, selecting hearing aid pattern and compensating psychoacoustic loudness. we expect that the advanced hearing aid telephone can be developed by the research about speech perception characteristics of the hearing impaired in engineering and clinical side.

In this study, we investigated the effects of pH, temperature, and salt concentration on protease activities in Hypsizygus marmoreus, and the ability of H. marmoreus extract to tenderize beef. In fact, H. marmoreus was shown to have higher protease activity than kiwi fruits. The pH of beef was dose dependently increased with addition of H. marmoreus extract. Cooking loss, cutting strength, and color value (L, a, b) were also dose dependently decreased with addition of H. marmoreus extract. In sensory assessments, H. marmoreus extract dose dependently enhanced perception of tenderness, flavor, and taste. In contrary, use of kiwi fruits as a meat tenderizer decreased positive perception of taste. The protease activitiy of H. marmoreus decreased sharply at pH < 2.0, and temperature > 50 ℃. Protease activity was relatively stable in NaCl concentrations ranging from 0-5 M, but incrementally decreased with increasing NaCl. These results suggest that, H. marmoreus extract can improve the texture and taste of beef.

This study investigated science education experts' perception of remote laboratory sessions (RLS) provoked by the COVID-19 pandemic. We conducted a total of 10 semi-structured interviews with experts in physics, chemistry, biology, and earth science education. As a result, science education experts primarily understood the RLS concerning pre-service teacher education and reconsidered the aim and goal of conventional laboratory education. On practices of RLS provoked by the COVID-19, they pointed out the learning loss due to deficiency of hands-on experience, decreased interactions between instructor and students, and instructors' increased burden. Meanwhile, they contemplated upon their adaptive implementation of RLS to suggest ways to improve RLS instruction and directions of post-COVID-19 science education. We recommend that RLS should be understood as a complemented version of minds-on teaching rather than a degraded version of hands-on teaching to elicit its full potentials. This study has its own significance providing an in-depth science educational perspective interpreting the RLS phenomena.
