  • Purpose: The purpose of this study is to compare sociocultural attitudes toward appearance, appearance satisfaction, and peer relationships between male and female middle school students, and to compare the effects of these variables on self-esteem in students of different genders. Methods: Data were collected in August and September of 2023 and analyzed using SPSS 24.0. Data were collected from 289 male and 240 female students through a survey, and descriptive statistics, x2 test, t-test, Scheffé test, and multiple regression analysis were conducted. Results: Female students showed significantly higher scores for sociocultural attitudes toward appearance (3.06±0.77 vs. 2.82±0.74), significantly lower scores for appearance satisfaction (2.55±0.46 vs. 2.71±0.40), and significantly higher scores for peer relationships (3.46±0.69 vs. 3.00±0.78) than male students. Additionally, self-esteem was significantly lower in female students (2.84±0.59) than in male students (2.95±0.51). As a result of adjusting for weekly allowance, subjective academic achievement, family economic status, stress, and experience of sadness or despair, which were significant in the univariate analysis, self-esteem increased as appearance satisfaction (p for all <.001) and peer relationships increased in both male (p=.009) and female (p<.001) students. In addition, sociocultural attitudes toward appearance did not have a significant impact on self-esteem in both male and female students. Among general characteristics, weekly allowance, subjective academic achievement, and stress were found to have a significant effect on self-esteem in both genders. Relationships with parents had a significant effect on self-esteem only in male students, and experience of sadness or despair had a significant effect only in female students. Conclusion: In order to improve self-esteem in both boys and girls, appearance satisfaction and peer relationships should be improved. As boys with poor relationships with their parents and girls with high levels of sadness or despair are particularly likely to have low self-esteem, they are to be considered as a high-risk group.

  • The study was intended to identify the nurses' experiences, understanding, and attitudes on DNR. Also, the study was to provide the data base for a standard of DNR decision-making and practice. The sample consisted of 347 nurses in eight general hospitals. The data were collected between August 1 and August 31, 2000. The data were analyzed using descriptive statistics and $x^2-test$. The results of the study were as follows : 1. Regarding DNR-related experience, 74.6 percent of the participants experienced DNR situations. Eleven percent of the participants received DNR education. DNR was most frequently (81.5%) requested by family members and relatives of patients. The decision-making on DNR was most frequently (76.8%) made by agreement between family members and medical staff. The DNR order was recorded at 81.9 percent on charts. Problems after DNR order were negligence in treatment and nursing care (30.6%) and guilty feelings due to doing the best (22.1%). CPR (cardiopulmonary resuscitation) was performed about 49.8 percent of DNR cases. 2. Regarding understanding and attitude on DNR, most of the participants (93.1%) thought DNR was necessary. The major reasons for the necessity of DNR were impossible recovery (44.4%) and death with dignity (41.1%). The decision-making on DNR was most frequently made by patient and family members (47.8%) and followed by agreement between family members and medical staff (25.6%), and patients themselves (16.4%). Most of the participants thought that medical staff must explain DNR to critical and end-of-life patients and their family members. Forty four percent of the participants thought that the most appropriate time for DNR explanation was when patients with critical disease were admitted to hospitals. Most of the participants (90.2%) thought a guide book for DNR is necessary to be made in hospitals. 3. There were significant differences in the participants' understanding and attitudes on DNR according to religion career education and experience of DNR. Of the participants those who have religions and education experience on DNR thought that there would be more DNR requests after DNR is explained to patients and family members (p<.05). In addition, there was higher understanding on the necessity of DNR in those who have more career and DNR experience(p<.01). The findings of the study suggest that a guide book for DNR need to be made with inclusion of legal, ethical, and cultural aspects. Also, there needs to be more education on DNR in medical ethics to health care professional and to provide more information on DNR to the general public.

  • PURPOSES : This study drew factors affecting motorcycle accidents in Seoul by severity using an ordered probit model and aimed to analyze and verify the drawn influence factors. METHODS : As the severity of the accidents could be classified into three types (fatal injury, serious injury and minor injury), this study drew the factors affecting accidents by a comparative analysis employing an ordered probit model, removed the variables that would not secure significance sequentially to construct a model with high explanatory power regarding the factors affecting the severity of motorcycle accidents, and calculated the marginal effect of each factor to understand the degree of each factor's impact on the severity. First, Model 1 put in all variables; Model 2 was constructed by removing the variables of the road surface conditions that could not meet the level of significance (p=0.608); Model 3 was constructed by removing gender variable (p=0.423); and Model 4 was constructed finally by removing age variable (p=0.320). RESULTS : As a result of an analysis, statistically significant variables were time of occurrence, type of accident, road alignment and motorcycle displacement, and it turned out that the impacts on the severity were in the following order: a road alignment of left downhill, the type of motorcycle-to-vehicle accidents and a road alignment of a flatland on the left. The significance of the models was tested using the likelihood ratio, the level of significance and suitability statistics about them, and as a result of the test, the significance level and suitability of the constructed models were all excellent. In addition, the model accuracy indicating the accuracy of a predicted value compared to that of the value actually observed was 70.3% for minor injury; 70.1% for serious injury; and 68.6% for fatal injury, and the overall accuracy was 70.2%, which was very high. CONCLUSIONS : As a result of an analysis of motorcycle accidents in Seoul through the ordered probit model and the marginal effect, it turned out that their severity increased in nighttime accidents as compared to daytime ones and gradually increased in the order of motorcycle-to-vehicle accidents, motorcycle-to-person ones and the ones involving motorcycle only. As a result of an analysis, the severity of accidents in road alignments of left downhill, left flatland and straight downhill increased as compared to those in a road alignment of straight flatland and that the severity of accidents of motorcycles with a displacement larger than 50cc was higher than that of those with a displacement smaller than 50cc.

  • The estimation of medical care status and the planning of health service program should be done according to each community resident's socio-medical background and public health service. In this point, it is most necessary to be set the exact and new socio-economic statistics data in Nepal, one of the worst countries in national health status. We surveyed 668 house, 3,425 residents in Dolka area, Nepal from January 25th to February 1st, 1995. 1. In personal characteristics, the ratio of men and women was similar, the person who were below 19 years old were 28.1% and the single were 52.4%. The illeterate person were 50.3% and the lower group in economic status which had been estimated by interviewers were 46.9%. 2. In sanitational characteristics, the person who used stream water or rainwater to drink were 42.2% and the person who always boiled water to drink were only 8.3%. The person who had not toilet in their house were 67.3% and the lower group in sanitational status which had been estimated by interviewers were 61.8%. 3. The prevalence rate of illness during the last one month were 8.6% and the chronic were 26.1% and the acute were 72.5%. The distribution of sickness symptom were headache, fever and joint pain in order and the person who took no medical treatment among the sick were 37.0%. The patterns of medical utilization were public health center, hospital and pharmacy in order. 4. Illness prevalence was significantly related to sex, age, merital status and educational experience. The residents who were women, 40 years old or more, married and had not educational experience were apt to take illness. 5. Medical utilization was significantly related to educational experience, job, distance from home to medical facilities and economic status. The person who had educational experience, were officer workers or merchants, lived near by medical facilities and had higher economic status took medical treatment very well.

  • This study was to provide basic materials to help reduce the fatigue by analyzing what effective factor the fatigue of hospital nurses in Gwangju and Jeonnam region. and what causes their fatigue. This descriptive research by Questionaires includes two hospitals in Gwangju. and seven hospitals in Jeonnam region, total 9 hospitals sampled at convenience sampling. The periods of collecting data was from Jul.22, 2002 to Jul. 30, 2002. Multidimensional Fatigue Scale; MFS, developed by Jang Se-Jin(2000) was taken to measure the fatigue. All collected materials were got the statistics by SAS for Windows Release 8.01. The result of this study was as follows. 1. This study included total 740 nurses, whose age ranged from 22 to 50; 30 years old by average. Nurses fatigue mean score was 90.24 (the scope by the measuring instrument is 19-133). Nurses at University Hospitals marked 92.36 and those at General Hospitals marked 87.91 in the mean score of fatigue. 2. They kept tired at work, and felt more tired while working at computer in the hospital. 3. The part of body in which they felt fatigue was the calf and $feet(36.6\%)$, the shoulders and back of the $neck(30.7\%)$, and the whole $body(10.8\%)$ and the reason that they felt tired at work was mental $stress(33.0\%)$, overworking(25.2\%)$, and irregular working $conditions(14.7\%)$ in order. 4. The solution to their fatigue at work appeared nothing by $50.1\%$, and the way of releasing fatigue after work indicated getting some $sleep(30.8\%)$, and taking a bath or a $shower(21.7\%)$ in order. 5. The degree of fatigue depending on whether they were satisfied with their pay and labor condition appeared low: and when they were satisfied with doctors. and when they were getting on well with caregivers. 6. The effective factor of the degree of fatigue appeared: the influence that fatigue in the hospital makes on daily life was $10.6\%$, the cause of fatigue at work, $9.3\%$, time of fatigue at work, $7.8\%$, the relationship with caregivers, $5.3\%$. and these explanatory$(R^2)$ variables.$33\%$. To conclude. the degree of nurses' fatigue appeared high. and it was higher in nurses at University Hospitals than in ones at General Hospitals. In addition, the influence that fatigue from the hospitals made on daily life was the most explanatory.

  • Joint channel assignment and routing is a well-known problem in multi-radio wireless mesh networks for which optimal configurations is required to optimize the overall throughput and fairness. However, other objectives need to be considered in order to provide a high quality service to network users when it deployed with high traffic dynamic. In this paper, we propose a re-configuration optimization model that optimizes the network throughput in addition to reducing the disruption to the mesh clients' traffic due to the re-configuration process. In this multi-objective optimization model, four objective functions are proposed to be minimized namely maximum link-channel utilization, network average contention, channel re-assignment cost, and re-routing cost. The latter two objectives focus on reducing the re-configuration overhead. This is to reduce the amount of disrupted traffic due to the channel switching and path re-routing resulted from applying the new configuration. In order to adapt to traffic dynamics in the network which might be caused by many factors i.e. users' mobility, a centralized heuristic re-configuration algorithm called State-Aware Joint Routing and Channel Assignment (SA-JRCA) is proposed in this research based on our re-configuration model. The proposed algorithm re-assigns channels to radios and re-configures flows' routes with aim of achieving a tradeoff between maximizing the network throughput and minimizing the re-configuration overhead. The ns-2 simulator is used as simulation tool and various metrics are evaluated. These metrics include channel-link utilization, channel re-assignment cost, re-routing cost, throughput, and delay. Simulation results show the good performance of SA-JRCA in term of packet delivery ratio, aggregated throughput and re-configuration overhead. It also shows higher stability to the traffic variation in comparison with other compared algorithms which suffer from performance degradation when high traffic dynamics is applied.

  • Domestic PB products have emerged and been distributed by hypermarkets, department stores, convenience stores, as well as TV home shopping channels and Internet shopping malls. However, the fierce competition among the distributors due to the emergence of the PB products have caused the diversion of consumers' recognition to be reduced weight and volume as well as had the effect of misleading consumers about the prices. The width of the PB product price's up and down is larger than the width of the NB product. Thus, following consumers' purchases of PB products, there has been an increasing number of consumer complaints. In order to research consumers' recognition of PB products and to examine how consumers' recognition and information search comparative to PB products affect consumers' dissatisfaction, an online survey targeted consumers with experience purchasing PB products. This study was conducted and analyzed using SPSS 19 Statistics. The findings can be summarized as follows. Even though more consumers who frequently purchased and used the PB products, the more they compared with information search comparative to the NB product and then purchased the PB product. We investigated the result that the relevant variables of consumer complaints have some relative influence in the purchasing of PB products. There will be a higher probability o the group having high recognition about price and safety not making consumer complaints in comparison with the probability of other consumers making complaints after the purchase of a PB product. Therefore, based on the results of this study, companies need to build a system so that they can figure out consumers' needs in order to prevent the occurrence of consumer complaints related to the products of distribution companies' brands. By means of the system, it is also necessary for companies to collect consumer complaints and analyze them by category. Then they eventually should develop a consumer-centered management system which may contribute to quality improvement, product development and the reduction of consumer complaints.
