This study is to evaluate the 'Private antidesertification afforestation support project' in the Kubuqi Desert through a survey of local residents and interviews with relevant personnel. Based on this survey, gender, age, and occupational differences in perception of the project were analyzed. In addition, the project was evaluated based on the OECD/DAC criteria using survey results and in-depth interviews with the relevant personnel. The survey analysis results show that the participants answered most of the questions positively, claiming that they were receiving social, economic, and environmental benefits through the project. However, most of the participants answered negatively to questions regarding the understanding of the project and relevant information. Gender differences in perception of the project were not found, whereas, age and occupational differences in perception were found. Older age groups showed higher levels of perception. Participants in the agro-livestock industry and office workers showed higher levels of perception compared to middle/high school students, the unemployed and college students. Teenagers, in particular, showed the lowest level of perception of the project, and thus, promotional activities targeting teenagers should be conducted in the future. Results of this evaluation of the project based on the OECD/DAC's five criteria (relevance, effectiveness, efficiency, impact, and sustainability) showed that the project operated effectively for the most part.
PURPOSE. The aim of this study was to obtain statistical data on the residual bone height at different natural tooth positions by panoramic radiography in edentulous Korean patients aged 60-90 years. MATERIALS AND METHODS. The study included the diagnostic panoramic radiographs of 180 randomly selected edentulous patients without systemic diseases affecting bone. The radiographic selection criteria included absence of obvious facial asymmetry, clearly visible anatomic structures, and no surgical and fracture history. The panoramic radiographs of 79 patients met these criteria and were used in the analysis. The same researcher processed all the radiographs by using a standardized method. The height of the residual bone was measured at 18 predetermined sites (7 in the maxilla and 11 in the mandible) on digitized and printed radiographs by using a Digimatic caliper, triangle, and ruler. Gender- and age-related differences were statistically analyzed by using the t-test and rank-sum test (${\alpha}=0.05$). RESULTS. The maxillary residual bone height did not show significant gender-related differences, but male patients had significantly higher residual bone in the mandible(P<.05). No significant height differences at the measured sites were noted among the 60s, 70s, and 80s age groups. CONCLUSION. Dentists should pay greater attention to older female edentulous patients because they are more prone to rapid residual bone resorption. Residual bone resorption may not be affected by age.
Objectives : This study was to investigate the characteristics of the heart rate variability(HRV), types of insomnia and accompanying symptoms of 175 insomnia patients. Methods : For this study we carried out HRV, Inbody of 175 patients with insomnia who have come to Dongeui oriental hospital of Dongeui university from the period of Janaury 2008 to September 2010. We studied the association of the insomnia patients' age and gender with HRV, accompanying symptoms and the types of insomnia. The information of the accompanying symptoms and types of insomnia was based on each patients' progress note. Results : l. There was no significant differences in the characteristics of HRV between male and female. 2. The most frequent symptom shown among the insmonia patents' was headache(41.14%). 3. Comparing the symptoms between the gender, female patients had more dry mouth, alternative periodic chill and fever, and hot flush symptoms than the male patients. 4. Comparing the symptoms between the age groups(divided in two), the lower age group (20~59) had more dizziness and constipation symptoms than the higher age group (over 60). 5. Comparing the types of insomma between the age group, the higher age group (over 60) had more termination insomnia. 6. The types of insomnia of the entire insomnia patients were onset insomnia (73.1%), maintenance insomnia(20.6%), termination insomma(l7.1 %), shallow sleep (52.6%), listed by order of frequency. 7. The patients who takes hypnotics had more anorexia symptoms than the patients who doesn't take hypnotics. 8. There was no visible differences of the average fractal portrait between male and female. The age group of 20~30yrs. had the highest average fractal portrait, and the age group of 30~59yrs. the second highest, and the age group over 60yrs. the lowest. 9. The average of the regulation reserves of the autonomic nervous system(B2) - was lower than the regulation level of the ANS at the present (Bl). 10. When compared the priority of the function of the ANS, it showed that the proportion of HF($38.61{\pm}29.19%$)was the most, and than VLF($30.65{\pm}23.36%$), LF($20.04{\pm}19.13%$) the least. 11. The average of the compensation level of the central nervous system at present(Cl) - was lower than the compensation reserves of the CNS(C2). 12. The average of the control reserves of the cerebrum(D2) - was lower than the control level of the cerebrum at the present (Dl). 13. There was no visible differences between different sexes and ages in pulse rate. 14. The abdomen fat ratio above the line of the insomnia patients was 77.97% in male and 93.1% in female. Both sexes showed that insomnia patients had more abdomen fat that the standard, and female patients had more abd. fat than male patients. Conclusions : This study shows that the HRV of insomnia patients had no significant differences between gender. Fractal portrait, HF, LF and VLF of the insomnia patients are in inverse proportion to the age. The study of the Body Component Analysis showed that female had more abdomen fat than male, and both gender showed more abdomen fat than the standard. When looked into the accompanying symptoms of the insomnia patients, the symptoms show differences according to gender, age and hypnotics taking, as shown as below. In the entire patients, Headache was the most accompanying symptom. Female had more dry mouth, alternative periodic chill and fever, and hot flush symptoms than male. Higher age groups had more dizziness and constipation as accompanying symptoms than lower age groups. Patients who takes hypnotics had more anorexia than those who dont.
The purpose of this study was 1) to investi-gate the trends of sex-role attitudes of women and 2) to examine the relations between sex-role attitudes and Yin-yang characteristics in clothing design. The survey was conducted among 317 women in Seoul and Kyunggi province. The results were as follows: 1) Androgynious gender and masculine gen-der with sex-role attitudes are strongly ap-peared among the low-age university students and not-married group. 2) Yang characteristics with light and cool-warm color to the clothing color and with clothing design are strongly appeared ming the low-age university students and not-mar-ried group. 3) Masculine attitude with clothing design preference attitudes are strongly appeared among the low-ager university students and not-married group. Many persons appeared to have feminine attitude rather than in andro-gynious attitude. 4) There are significant differences between sex-role attitudes and yin-yang characteristics to the clothing design. A high level of mascu-line gender is storngly indicated the yang characteristics with saturation to the clothing colorand and with clothing design 5) There are significant differences between sex-role attitudes and clothing design prefer-ence attitudes.
Dexterity is defined in the present study as interdigital manipulative skill or the fine manipulative movements of objects held between the thumb and fingers. The Grooved pegboard test has been used to evaluate dexterity requring visual-motor coordination. The purpose of this study was to standardize the completion time of the Grooved pegboard test in different age groups and gender. Normative values for the Grooved Pegboard Test was developed on the sample of 282 healthy volunteers (89 men and 183 women). Subjects were stratified according to gender and dominant hand and were subdivided into six groups by blocking. The results of this study were as follows: 1) There was a significant difference in completion time between dominant and nondominant hand in both men and women groups (p<.05). 2) There were significant differences in completion time between men and women group (p<.05) 3) There were significant differences in completion time among age groups (p<.05).
In this study, we analyzed the old`s characteristics for depth perception in comparison with the young`s as a basic study for universal design in field of products or facilities. Twenty three of the old and twenty two of the young had participated and the depth perception apparatus was used in this experiment. Gender, viewing distance, and age were considered as factors and the differences of depth perception were analyzed for each experimental condition. In the result, a significant difference was not detected on gender, but significant differences were detected on age and viewing distance. That is, we can see that the old is remarkably worse than the young on depth perception task. Therefore, it means that these characteristics have to be absolutely considered in user interface design to improve the old`s accessibility for products or facilities.

The study seeks to determine how much environmentally conscious behaviors vary depending on the nationality, gender and age. For its purpose, this study suggests hypotheses that Korean and American consumers, who are culturally different from each other, show differences from each other in environmentally conscious behaviors. An interaction effect is also expected between gender and age. With regard to environmentally conscious behavior. Meanwhile, the study tried to examine whether personal values have any mediating effect on the behaviors. The findings of this study can be summarized as follows. Environmentally conscious behaviors by American consumers were more significant than those by Korean consumers. And men were more positive in making environmentally conscious behaviors than women were. In addition, there were interaction effects between nationality and gender, and nationality and age. Furthermore, personal values, depending on age, were found to have moderating effects on environmentally conscious behaviors.
This study attempted to analyze human brain responses toward visual content through EEG signals and intended to measure brain wave reactions of different age groups to determine the sexuality level of the media. The experimental stimuli consist of three different video footage (rated ages 12, 15, and 18) to analyze how subjects react in situations where they actually watch sexual content. For measuring and analyzing brain wave reactions, EEG equipment records alpha, beta, and gamma wave responses of the subjects' left and right frontal lobes, temporal lobes, and occipital lobes. The subjects of this study were 28 total and they are divided into two groups. The experiment configures a sexual content classification scale with age or gender as a discriminating variable and brain region-specific response frequencies (left/right, frontal/temporal/occipital, alpha/beta/gamma waves) as independent variables. The experimental results showed the possibility of distinguishing gender and age differences. The apparent differences in brain wave response areas and bands among high school girls, high school boys, and college students are found. Using these brain wave response data, this study explored the potential of developing algorithm for measurement of age-specific responses to sexual content and apply it as a film rating.
Magnetic resonance imaging(MRI) has become an important technique for examining changes in human brain structure with neurological disorders. Brain development is a very complex process, and is affected by neurogenesiss and genetic programs. As age increases, structures of the brain change, which can contribute to the formation of brain diseases. Among the various factors, Gender is one of the greatest influential factors that affect the development of a healthy brain. The images were analyzed through various programs found in FSL such as SIENAX, FIRST, and Vertex analysis. Our results show that significant gender-related differences in subcortical areas were observed at the particular age group. The magnitude of these differences between gender and volume varied depending on the area investigated. In this study, we used more advanced 3T MRI for the structural analysis of subcortical structures between each gender. In addition, Vertex Analysis was used to visualize the volumetric differences in subcortical structures between each gender. This study is limited to groups in their 70s, therefore, further studies are needed for wider age groups.
The purpose of this study was to investigate the creativity and problem-solving of EMT students in Gwangju Metropolitan City. Data was collected by self-reported questionnaire from 106 EMT students from December 1, to December 20, 2008, Data collected were analyzed by technical statistics and correlation analysis using $SPSS/PC^+$ 12.0 program, The results were as follows : 1. The subjects were 49 males (46%) and 57 females (54%). 2. According to gender characteristics and creativity of the subjects, there were not significant differences(t = 1.02, p = .312). To gender characteristics and problem-solving of the subjects, male were higher grade more than female and there were significant differences(t = 2.04, p = .044). 3. According to age characteristics and creativity of the subjects, there were not significant differences(F = 8.73, p = .421). To age characteristics and problem-solving of the subjects, there were not significant differences(F = 2.314, p = .104). 4. There was positive correlation between creativity and problem-solving(r = .489, p = .000). Therefore, these findings showed that more studies needed about creativity and problem-solving on EMT students and creative problem-solving programs be started for these EMT students in order to development their creativity and problem-solving.
