The purpose of this study was to develop and validate the Psychological Difficulties Scale of Working Moms(PDSWM). In the first study, 69items and 17 factors of the inventory were obtained based on interview, open-ended questionnaires. In the second study, the on-line surveys from 306 working mom was carried to analyze factor structure of the PDSWM. The final result showed that the 12 factor model with 64 items was appropriate. The third study was collected from 638 working mom and in order to make certain the cross-validity of the inventory, the group was divided into two groups (each group with 319 employees). The results of exploratory factor analyses using data of group 1 showed that the 8 factor structure with 48 items was appropriate. Also the results of confirmatory factor analysis using data of group 2 showed that the 8 factor structure indicated a satisfactory fit. Final 8 factors were as follows: 1) Feeling Apologetic to family members 2) Discrimination at workplace 3) burnt-out: both body and mind 4) Unequal distribution of child-rearing and house chore labor 5) Conflict with the babysitter/grandparents 6) Limit in further strengthening work competency 7) Social prejudice 8) Difficulty being on time for work. The PDSWM was significantly correlated with various criteria such as organizational commitment, life satisfaction, and work engagement. Based on such findings, implications, limitations, and the suggestions for future study were discussed.

As the use of smartphones has rapidly increased due to the development of digital technology, the expansion of smartphones, and the COVID-19 incident, dependence on smartphones and the Internet is emerging as a serious social problem. As one of the solutions to the smartphone overdependence problem, the government and companies are releasing smartphone overdependence prevention applications. However, research on the effectiveness of smartphone overdependence prevention applications is insufficient. Therefore, this study selects 25 applications serviced in Korea as analysis targets and evaluates smartphone overdependence prevention applications in terms of function and service using the FGI survey method to identify problems and propose improvements. In the function evaluation, the functions of blocking illegal/harmful apps/websites, limiting smartphone usage time, and monitoring smartphone usage status are provided in most applications, so satisfaction scores are also highly evaluated. However, functions such as location check, smombie prevention, and body camphishing prevention served by some applications are evaluated low due to poor performance and poor accuracy. Classified by service provider, government-providing applications need to accurately perform functions and improve convenience of use. Mobile-Carrier-providing applications need to improve connectivity with other carriers and compatibility with other smart devices like smartphone, tablet, etc. Other private enterprise-providing applications need to open AS channels such as customer service centre and chatbot to improve service.
The mandibular advancement device(MAD) has been used to help manage snoring and obstructive sleep apnea. The aims of this study were to specify the demographic and clinical characteristics of the patients receiving long-term treatment with MAD and to quantify the compliance with and side effects of the use of the device. Of 103 patients who were treated with MAD for at least one full year after delivery date, 49 were able to be contacted with telephone and complete follow-up questionnaires were obtainable. They were telephoned to determine whether they were still using the device. If not, they were asked when and why they stopped using it. Patients were also asked how much effectiveness of the MAD in decreasing snoring and how much they and their bed-partners were satisfied with the MAD therapy. The initial respiratory disturbance indices and pre-treatment snoring frequency and intensity were obtained from the medical records of initial visit. All the data were compared between users and nonusers. The results were as follows: 1. Of 49 patients 25 are still using the device, but 24 stopped using it. Among nonusers nobody stopped wearing the device within first 1 month, but 37.5% of nonusers stopped wearing it in the following 6 months, and another 4.2% before the end of the first year. 2. The one-year compliance of the MAD therapy was 79.59%. 3. There were no significant differences in mean age, mean body mass index, and gender distribution between users group and nonusers group. 4. There was no significant difference in mean respiratory disturbance index at initial visit between users group and nonusers group. 5. There was no significant difference in pre-treatment snoring frequency and intensity between users group and nonusers group. 6. The degree of decrease in snoring with use of MAD was significantly higher in the users when compared to nonusers. 7. Patient's overall satisfaction with treatment outcome was significantly higher in the users when compared to nonusers. 8. Bed partner's satisfaction with treatment outcome tended to be higher in the users when compared to nonusers. 9. The most frequent reasons why patients discontinued wearing the MAD were: jaw pain(25%), dental pain(20.83%), broken appliance(20.83%), hassle using(16.67%), lost weight(8.3%), dental work(8.3%), no or little effect(4.17%), sleep disturbance(4.27).

Purpose : Adolescence is a period of growth and development in body structure and physiologic, psychologic, and social functioning. Smoking and drinking in this period are very harmful and may lead to other forms of substance abuse. We surveyed the actual aspects of smoking and drinking among Korean adolescents and analyzed associated factors. Methods : A survey was performed among adolescents using a questionnaire about smoking and drinking. Data were collected from students who visited pediatric clinics for routine school examinations from July to November 2007. Results : A total of 2,546 adolescents (smoking 1,512; drinking 1,034) participated in the study. The overall smoking and drinking rates were 29.2% and 48.2%, respectively, and the mean age at the first instance of smoking and drinking was 13.8 and 14.1 years, respectively. Among drinking adolescents, 30.1% were offered a drink by their parents, although most adolescents were encouraged to smoke or drink by their friends. Dissatisfaction with family and school life, economic status, and school performance was associated with a higher smoking and drinking rate (P<0.001). Broken families were associated with a high rate of smoking, but peer satisfaction was not related to smoking or drinking. The frequency and amount of smoking and drinking in adolescents were as high as those in adults. Social sanctions seemed insufficient to keep adolescents from smoking and drinking. Conclusion : Adolescent smoking and drinking are highly influenced by family and school environments, so more active social sanctions are required, including parental involvement and legislation preventing adolescents from smoking and drinking.

With an increase in the aging population and a rising social interest in health and welfare, studies to improve healthcare in the elderly are being actively conducted. This study attempted to improve the current design and manufacture of elevating electric wheelchairs to enhance user safety and convenience. Seat design based on the user's body shape, convenience while boarding or alighting, caster turning radius and, safety and stability features that prevent shaking when the user gets up or sits down were improved. A driving experiment was conducted to evaluate the operation of the indoor electric wheelchair designed and manufactured with these additional functionalities. During the test, the performance parameters evaluated were continuous driving time, turning radius, maximum lifting and lowering load, maximum lifting height, noise level, minimum distance sensing by the driving auxiliary sensor, ability to interact with server and app programs, and the duty cycle maximum error rate. The test confirmed that this improved electric wheelchair successfully met target parameters. In a future study, we will evaluate this improved electric wheelchair from a user's perspective for its usability parameters, such as satisfaction, convenience and stability.
With the subjects of male consumers in their 20s to 40s living in the Ningbo area in Zhejiang Province, this study aims to investigate into the reality of their purchase attitude and size fitness of ready-made suits. The results are as follows; Looking into their demographic characteristics, 70.6% of the subjects were twenties, 60.6% were single, and educational career stood in the order of college, middle school, and high school graduation. They were largely absorbed in free trade, followed by teaching, commerce and service industry. 59.6% of them were Zhejiang Province belongs. One to two thousand yuan was the greatest portion of their monthly income. As for their purchase attitude of ready-made suits, they thought higher of material, quality, activity, and solidity than of design. They preferred to buy clothes at a department store. There was significant difference between purchase frequency and purchase price according to monthly income and jobs. Concerning brand recognition, the Chinese subjects favored "Youngor." Though Korea's brands were very lowly recognized, Korean products received really high recognition. Compared with China's brands, they found foreign brands excellent in design, followed by material/matter, wear, and sewing. As to their physical satisfaction and the size fitness of clothes, most subjects felt happy with their sizes. Trousers and jackets were among the unfitting suit items, while the girth of waist was the least satisfactory size. Therefore, in order to raise the market occupation rate of Korean suit goods in China, more aggressive marketing strategies are required to utilize the current Korean-style entertainment and maximize concerning brand images. In particular, outstanding products in consideration of prices should be made through the proper patternmaking to reflect the body types of the Chinese.
Studies were undertaken on the changes in the renal blood flow by relating them with the alterations in the amplitudes in the rheogram of rabbits. The changing pattern of the electrical conductivity was recorded by means of the needle electrodes inserted into the kidney and the surrounding aluminium foil which was grounded. The Impedance Rheograph manufactured by the Narco Company was used. The small artifact which persisted after ligation of the renal vessels was subtracted from the value obtained in each pulsatile wave in the rheogram. The animals were nembutalized intravenously, 30 mg/kg. A plastic canule was inserted into the carotid artery and the arterial blood pressure was monitored continuously with the pressure transducer connected to the physiograph. Stepwise bleedings were performed on the animal. The first bleeding was between 13 to 18 ml in the amount, and it was folowed by consecutive hemorrhages, 5 or 10 ml each time. The total amount of bleeding was summed as much as 1.5-2% of the body weight. Two minutes fter each bleeding th arterial blood pressure, ECG and the rheogram were taken. That was the necessary time to obtain the stabilized picture of each parameter. After closing the bleeding process, the shed blood was retransfused into the animal and the response in the renal blood flow was observed as well as the arterial blood pressure. Particularly the presence or absence of the autoregulatory mechanism in the situation of the hemorrhage was also studied. The results obtained were as follows: 1. In 7 cases out of 22, that was about one third of the total number of experiments, the autoregulatory mechanism of the renal blood flow persisted even in acute hemorrhage, and the decreases in the renal blood flow were less than 10% of the control values even when the arterial blood pressure dropped to 66-87% of the original value obtained before the bleeding. 2. Because of the stepwise bleeding the exact blood pressure at which the renal blood flow reduced as much as one third of the control value could not be obtained. However, the results revealed that the approximate pressure, expressed as percentage of the control value, was 50-60% in 3 cases, 61-70% in 4 cases and 71-80% in 8 cases. In one case the decrease in the renal blood flow exceeded one third of the control value before the pressure dropped to 80% of the control. 3. In 19 cases the decreases in the renal blood flow exceeded one half of the control values by hemorrhage. Then the arterial blood pressure revealed less than 40% of the control value in 6-cases. In 2 cases the pressure was 51-60% of the control pressure. In 5 cases the range of bleed pressure was 61-70%, and in e remaining 6 cases the pressure ranged from 71 to 80% of e control value. 4. Out of 15 cases of retransfusion after definite decreases in the renal blood flow loller·ing the hemorrhage, 9 cases restored their renal blood flow. On the contrary 6 cases showed low values even when the shed blood was retransfused. 5. Theories concerning the mechanism of the autoregulation of the renal blood flow were reviewed for the purpose of explanation of the results obtained. However, there are much to be done before greater satisfaction

The purpose of this study was to analyze the perception of child abuse by parents and early childhood teachers. For this purpose, a questionnaire survey was conducted with parents and early childhood teachers belonging to kindergarten in G district. The frequency, percentage, mean and standard deviation were calculated using the SPSS 21.0 program, and the t-test and the ${\chi}^2$ test were used to obtain data on child abuse(physical, language, emotion and thinking, neglect, preventive measure, improvement plan). The results of this study are as follows: First, the difference of perception about child abuse was higher in early childhood teachers than parents. Recognition of subordinate content is neglected in both parents and early childhood teachers, body, emotion and thinking, and language. Second, parent awareness of child abuse prevention education and participatory seminar education was more perceived than subcontent of preventive measures. The awareness and satisfaction of child abuse preventive education, the awareness of the legal role and function of the child protection agency, the mandatory reporting of child abuse, and the perception of the obligor were more perceived by early childhood teachers. Third, the subcontracting of the child abuse improvement measures, the provision of child abuse preventive education and provision of data, the actual situation of child abuse through mass media and promotion of measures, expansion of child abuse prevention education using mass media, Teachers were more aware of education. These results are expected to provide basic data on understanding and recognition of the prevention of child abuse by parents and early childhood teachers.
This descriptive study was conducted to identify the relationship between knowledge of stroke and stroke-related health promoting lifestyle among nursing students. Data were collected from September 21 to 26, 2020, from 182 nursing students. Data were self-reported using a structured questionnaire. Data were analyzed using independent t-test, one-way ANOVA, and Kruskal-Wallis test. The mean stroke knowledge score of the participants was 14.97±3.13. The mean score on knowledge of stroke risk factors was 8.69±1.98, and that for knowledge of stroke warning signs was 5.43±1.31. The mean health promoting lifestyle score was 2.93±0.47. Knowledge of risk factors according to general and health-related characteristics showed significant differences in age and money on hand. Knowledge of warning signs according to general and health-related characteristics showed significant differences in the family history of stroke. Health promoting lifestyle to general and health-related characteristics showed significant differences in religion, satisfaction with major, subjective health status, and body mass index. In conclusion, nursing students had high knowledge of stroke, but stroke-related health promoting were not.
This paper proposes AR stone tower content, an experiential content based on wearable augmented reality (AR). Although wearable augmented reality is gaining attention, the acceptance of the technology is still focused on specialized applications such as industrial sites. On the other hand, the proposed AR stone tower content is based on the material of 'stone tower' so that general users can relate to it and easily participate in it, and it is organized to utilize space in a moving environment and find and stack stones based on natural hand gestures. The proposed AR stone tower content was implemented in the HoloLens 2 environment and evaluated by general users through a pilot exhibition in a small art museum. The evaluation results showed that the overall satisfaction with the content averaged 3.85, and the content appropriateness for the stone tower material was very high at 4.15. In particular, users were highly satisfied with content comprehension and sound, but somewhat less satisfied with object recognition, body adaptation, and object control. The above user evaluations confirm the resonance and positive response to the material, but also highlight the difficulties of the average user in experiencing and interacting with the wearable AR environment.
