Concentrations of fine particulate matter ($PM_{2.5}$) and several of its particle constituents measured outside homes in Houston, Texas, and Los Angeles, California, were characterized using multiple regression analysis with proximity to point and mobile sources and meteorological factors as the independent variables. $PM_{2.5}$ mass and the concentrations of organic carbon (OC), elemental carbon (EC), benzo-[a]-pyrene (BaP), perylene (Per), benzo-[g,h,i]-perylene (BghiP), and coronene (Cor) were examined. Negative associations of wind speed with concentrations demonstrated the effect of dilution by high wind speed. Atmospheric stability increase was associated with concentration increase. Petrochemical source proximity was included in the EC model in Houston. Area source proximity was not selected for any of the $PM_{2.5}$ constituents' regression models. When the median values of the meteorological factors were used and the proximity to sources varied, the air concentrations calculated using the models for the eleven $PM_{2.5}$ constituents outside the homes closest to influential highways were 1.5-15.8 fold higher than those outside homes furthest from the highway emission sources. When the median distance to the sources was used in the models, the concentrations of the $PM_{2.5}$ constituents varied 2 to 82 fold, as the meteorological conditions varied over the observed range. We found different relationships between the two urban areas, illustrating the unique nature of urban sources and suggesting that localized sources need to be evaluated carefully to understand their potential contributions to $PM_{2.5}$ mass and its particle constituents concentrations near residences, which influence baseline indoor air concentrations and personal exposures. The results of this study could assist in the appropriate design of monitoring networks for community-level sampling and help improve the accuracy of exposure models linking emission sources with estimated pollutant concentrations at the residential level.

This study, a quasi-experimental study using a nonequivalent control group pretest-posttest design. conducted a survey on 30 patients test group and control group of IS patients sampling an adjacent population at random - who are operated on the breast cancer and are in the A University Hospital located in Suwon, to examine into the effects of foot reflex zone massage on their pain and sleep satisfaction through the nursing interventions. It gave them a foot reflex zone massage for the total 30 minutes-basic massage 10 minutes and reflex massage 20 minutes required to alleviate their pain day in day out covering a two-month period from the first of July to the first of September 2004. for the purpose of collecting data. It launched into a two-round foot reflex zone massage at 6 and 24 hours since mastectomy through a direct visit at the hospital room to measure pain intensity, physiological index(pulse and blood pressure) and sleep satisfaction of them. The results are as follows. First, it showed that there is all the difference between pain intensity of test group and that of control group. In result, the first hypothesis, pain of test group. which measure at 6(p=.000) and 24 hours(p=.001) since mastectomies, will be bigger than that of control group, was established. Second, it showed that there is all the difference between physiological index of test group and that of control group. In result. the second hypothesis, pulse(p= .025, p= .002), systolic blood pressure(p= .004, p=.012) and diastolic blood pressure(p=.004. p= .003) of test group, which investigate at 6 and 24 hours since mastectomies, will be bigger than that of control group, was established. Third, it showed that there is a significant difference between sleep satisfaction of test group and that of control group(p=.000). In result, the fourth hypothesis, sleep satisfaction of test group. which examine in the morning after mastectomies, will be bigger than that of control group, was established. In the result. a foot reflex zone massage is seen to be effective in the pain reduction and sleep promotion of patients who are operated on breast cancer, and in providing them with more qualitative care by improving confidence between them and nurses through a physical touch. Also, it can be applied to a clinical examination through an independent nursing intervention.

The purpose of this study was to evaluate the removable partial denture prescriptions including surveyed crowns and design of component parts sent to the laboratory technician. A total of 351 casess with prescription forms and master cast in maxillary and mandibular semi-edentulous situations collected from dental laboratory by random sampling were selected for this study. The evaluation and study observed here involved the classification of edentulous situations, status of abutment splinting, form of rest seats and guiding plane of surveyed crows, location of maxillary major connectors and tripodig marks on the master casts. Removable partial denture prescriptions contained (1) general request (upper and lower cast framework), (2) types of metal, (3) location of retainer(retention, lingual bracing, rest area, guiding plane surface), (4) location and type of major connector, (5) relief area and amount, (6) and other specific instructions. The following informations based on the classified groups such as Group I was those cases sent with no real prescriptions. They say 'make a partial.' No prescriptions, no thought beforehand, Group II was those cases sent with a minimal prescriptions. They say 'make a partial with clasps on May be some preparations, usually inadequate. Group III was those cases sent with a moderately good prescription. Adequate but could be much better. No tripoding but it tell what clasps go where. Still not good prescriptions. Group IV was good cases, tripoded with adequate prescriptions and a prescription which exactly describes what is expected from the laboratory. The analyzed results were as follows: 1. The normal form of rest seats and guiding plane of surveyed crowns in Class. I and Class. II edentulous situations on the maxillary cast were observed 31.9% and 27.89%, respectively. The abutment teeth and retainer without occlusal rests of Class. I and Class. II were showed 11.58% and 8.86%, respectively. In mandibular cases, the normal form of rest seats and guiding plane of surveyed crowns showed 27.54% and 8.82% in Class. I and Class. II situation. The abutment teeth and retainer without rest seats were showed 15.19%, respectively. 2. The splinted surveyed crowns of Class. I and Class. II maxillary edentulous situations in distal extension cases were showed 34.51% and 28.85%, but 28.52% and 10.29%, respectively. 3. The location and type of maxillary major connector delineated on the master cast were 66 cases (44.89%). 4. The results of 351 cases were classified as Group I 146(41.59%), Group II 115 (32.76%), Group III 57 (16.23%), and Group IV 33 (9.48%). 5. The delineation of abutment tooth for clasping were 176 cases (50.14%) among total of 351 cases. 6. The delineation of height of contour line were showed 45 cases (12.8%) in Group II, 14 cases (3.98%) in Group III and 33 cases (9.40%) in Group IV with total 92 cases (26.21%). 7. In surveying procedure, the delineation of tripoding marks and reference line were showed 17 cases (4.84%).

Objectives: The purpose of this study was to assess input for health promoting schools (HPS), and to evaluate HPS based on WHO's guidelines through school characteristics, and to identify the schools' need among six areas of HPS. Methods: A stratified and random cluster sampling design was used to obtain a cross-sectional sample. A total of 59 elementary, middle and high schools in Seoul and Gyeonggi areas were included, and 333 teachers (males 40.6%, females 59.4%) participated in this survey. A self-reported questionnaire consisted of ten items for input for HPS, 50 items for the evaluation of HPS and three items for the schools' needs among six areas of HPS. Data was analyzed through a t-test, ANOVA, and a Duncan test. Results: The mean score of input for HPS was 48.5 ($\pm$15.3). Elementary schools had higher mean scores of input than middle schools. The mean score of schools with a management committee was higher than those schools without it. The schools which had meetings on health issues had higher mean scores. The mean score for HPS was 76.8 ($\pm$9.4): the area of "School Physical Environment" had the highest score (80.0$\pm$10.9), and the area of "Community Relationships" had the lowest score (67.1$\pm$13.9). Elementary schools had higher mean scores of HPS than middle and high schools. The schools which had less than nine classes and more than 31 classes had higher mean scores. The mean scores of schools with less than 340 students and more than 1201 students had higher. The schools which had meetings on health issues had higher mean scores. The same results were found on six areas of HPS. The teachers responded that the areas of "School Health Policy", "The School Physical Environment", and "Health Service" should be supported among the six areas of HPS. Conclusion: Based on these results, more concerns and support for school health are necessary. Middle schools should give more regard on the development of HPS. For comprehensive school health promotion, all six areas of HPS should be equally supported.

Purpose - Today, the importance of the service industry has increased. Social welfare businesses that follow the non-profit principle have neglected the distribution of the service. However, an intangible service, when produced and consumed, has a similar service delivery system to common service distribution and social welfare. Therefore, the author has assumed the efficiency of the service delivery system of social welfare to be equivalent to the service distribution industry. Hence, various kinds of social welfare services for the prevention of elderly suicide, from the perspective of distribution, are discussed. Studies on generational relations have thus far investigated depression from parent-children conflict, and satisfaction with their lives. Studies on the relationship between family solidarity and elderly suicide by analyzing existing social problems are rare. This study investigated the effects of family solidarity between old parents and adult children upon elderly suicide by analyzing serious psychological and social problems. This study revealed basic measures for elderly suicide prevention through services that could elevate family solidarity from the perspective of social welfare service distribution. Research design, data, and methodology - The subjects were 468 elderly, 65 years or older, at 18 senior welfare centers and halls for the elderly at Seoul and Gyeonggi-do. Questionnaire surveys, excluding invalid answers, were analyzed. Convenience sampling was used from February 5, 2014 to March 5, 2014. The findings were: First, women and those having spouses with advanced educational backgrounds and social activities had primary solidarity such as contact solidarity, affectionate solidarity, functional solidarity (giving help), and functional solidarity (receiving help). In addition, those who had good health, from a subjective point of view, had more solidarity. Second, the elderly who were men and single, and who had poorer educational backgrounds thought of suicide, lacked social activities, and had poor health, from a subjective point of view. Third, family solidarity between old parents and adult children had significantly negative influence on the suicidal ideation of the elderly. Results - The study revealed the following implications. First, the preparation for old age should consider not only economic welfare but also the psychological welfare due to the relationship with children. Second, the phenomenon of elderly suicide because of a lack of family solidarity could increase national loss and have great influence upon welfare in old age. Therefore, planning of welfare services for the elderly should consider the value of relationships with children to improve the psychological welfare of the elderly. Third, the social expenses of government-oriented support for parents should be discussed from the people's point of view. Conclusions - The subjects of the study comprised the elderly at Seoul and Gyenggi-do; therefore, it would be difficult to extrapolate the findings to all the elderly in the nation. The subject visited senior welfare centers as well as halls for the elderly; therefore, it would be difficult to assume that the trends were representative of the elderly in the nation.
