The purpose of this study is to provide the information of the aged olds for which basic data are almost no available. The subjects were divided on the base of age 75. The elderly under 75 were named 'the young olds' and over 75 were 'the aged olds'. The aim of this research is to promote health and to improve nutrition, and the survey was made for health promotion behaviors, habits against health risk, dietary management status and diet intake. And it was conducted by 24 hr-recall method and analyzed by nutrients intake. 242 subjects were collected in 12 cities or counties in Gyeonggi Province and 20 elderly people (10 male and 10 female) were selected out of 1 village in each district. Questionnaire about health behavior and dietary management was carried out by interview method through regional home extension workers. Statistical analyses were made by SAS (version 8.1) and Chi-square tests and General Linear Models were used. Out of the subjects the aged olds over 75 was 31.9%, elementary school educated (93.5%), with spouse (40.3%), with adult children(28.6%), monthly living cost of 500-1,000 thousand won(40.3%). Mean age was 78.82 years compared with 69.75 years of the young olds. 46.8% of the aged olds used monthly pocket money over 1000 won and it was lower than 63.3% of the young olds. Only half of the aged olds had regular exercise of walking (77.8%) or with athletic equipment (17.8%). However, the young olds did more frequent walking (82.1 %) and less exercise with athletic equipment (4.8 %), which was significantly different. Kinds of disease were different with the young or the aged olds, as more proportion of cardiovascular disease(37.9%) for the young olds and joint lumbago neuralgia(41.6%) for the aged olds. Dietary management was good (3 meals per day: 93.4%, fixed mealtime: 72.4%, and regular amount: 79.9%). But there was significant difference in side dish varieties and kinds of snacks; for the aged olds only 8% had over 5 sorts (compared with 18.8% of the young olds) and the kinds of snacks were cookie, candy, juice, carbonated beverage for the aged olds (compared with noodle, milk, soybean-milk for young olds). The ratio of nutrients intake (energy, riboflavin and niacin) with RDA was significantly higher for the aged olds than that of the young olds. The surveyed subjects had no difficulties in Activities of Daily Living (ADL), but some of the aged olds had difficulties in Instrumental Activities of Daily Living (IADL) like housekeeping, using transportation, going shopping and making phone calls. These results suggest that low quality of life is linked with low economic status of the rural elderly and congregate meal at village hall would be required because of the lack of side dishes variety for the aged olds. And nutrition education program about good snacks and exercise practice would be needed for the aged olds. By operating nutrition education program the aged olds would enjoy better quality life maintaining or ameliorating IADL abilities.

The purpose of this study is to search how to promote health and improve nutrition and health care of the elderly people in rural area. Behaviors for health promotion and habits against health risk were surveyed. Dietary management was analyzed for surveyed nutrient intake by 24 hr -recall method. 242 subjects were collected in 12 cities or counties in Gyeonggi Province and 20 elderly people (10 male and 10 female) were selected out of 1 village in each district. Questionnaire for health behavior and dietary management was carried out by trained interviewers. Statistical analyses were made by SAS (version 8.1) and Chi-square tests and General Linear Models were used. Characteristics of the elderly people were 61-74 year-olds (68.2%), elementary school educated (78.4%), with spouse (51.7%), monthly living cost of 500-1,000 thousand won(43.4%), and monthly pocket money of 50-100 or 100-200 thousand won(33.5%, 26.5%). 41.4% of the subjects checked up medical examination regularly. The alcohol drinking status was significantly different according to gender: high no-drink rate of female (52.5%) and low no-drink rate of male (25.6%). Kinds of disease were different according to gender: higher proportion of cardiovascular disease(46.3%) and diabetes mellitus(8.1 %) in male and joint lumbago neuralgia(44.4%) and osteoporosis(8.6%) in female. Gastrointestinal complaints were nausea (69.0%) and chronic indigestion (17.8%). Constipation (12.0%) and vomiting (4.3%) were more frequent in female. Dietary management was good (3 meals per day: 93.4%., dining with family: 72.4%, regular mealtime: 72.4%, and 3-4 times of snacks per week: 44.9%) except side dish taking of 3-4 kinds only. However, almost one-third of the female elderly ate alone (30.6%) which was well compared with one-fifth of the male (19.7%). And food and nutrients intake were not significantly different according to gender except that male elderly's intake of energy and protein was lower than that of female's. The surveyed subjects had no difficulties in Activities of Daily Living (ADL), but some female elderly had some difficulties with Instrumental Activities of Daily Living (IADL) like working at home, using transport, and going shopping. These results suggest that low quality of life linked with low economic status of the rural elderly and that congregate meal at village hall would be required for the female elderly eating alone. For the undernourished male elderly, it would be needed to provide snacks and to establish nutrition and health surveillance system.

1. Objectives The Sasang Constitution has been studied in many parts and one of the most common inquiries is the self-reporting questionnaire. But the established investigation has the problem that the respondents are not fully aware of the questionnaires and answer them. To settle this problem, it's been made new questionnaires through two steps. 2. Methods At first step, the testers ate classified into Yangin(陽人) and Eumin(陰人). And then, Taeyangin is distinguished from Soyangin likewise Taeumin is told from Soeumin. It's called 'The Two Step Questionnaire for the Sasang Constitution Diagnosis(TS-QSCD)'. This new method is tested by 160 testers and Woosuk university students whose constitution ate confirmed to make clear clinical uses 3. Results and Conclusions Questionnaire Sasang Constitution corresponds with The Real Sasang Constitution at the rate of 71.87%. Only 5.63% has shown an error at the first step. Every experimenters by constitutions, the 56 objects of 74 Taeumin are confirmed the same as it is. It has 84.85% accuracy. The 27 objects of 32 Soeumin come to the same thing and it has 69.23% accuracy. Similarly, the 32 objects of 42 Soyangin come to the same conclusion and 72.73% accuracy high As the result, in comparison to the Real Constitution with the Constitution by questionnaires, the accord comes out Kappa Indices 0.6427866. This result is comparatively high. Chi-square Test can be shown statistical meaning as well.

Purpose: To investigate the prevalence of bifid and trifid mandibular canals using cone-beam computed tomography (CBCT) images, and to measure their length, diameter, and angle. Materials and Methods: CBCT images of 500 patients, involving 755 hemi-mandibles, were used for this study. The presence and type of bifid mandibular canal was evaluated according to a modified classification of Naitoh et al. Prevalence rates were determined according to age group, gender, and type. Further, their diameter, length, and angles were measured using PACSPLUS Viewer and ImageJ 1.46r. Statistical analysis with chi-squared and analysis of variance (ANOVA) tests was performed. Results: Bifid and trifid mandibular canals were found in 22.6% of the 500 patients and 16.2% of the 755 sides. There was no significant difference between genders and among age groups. The retromolar canal type accounted for 71.3% of the identified canals; the dental canal type, 18.8%; the forward canal type, 4.1%; and the trifid canal type, 5.8%. Interestingly, seven cases of the trifid canal type, which has been rarely reported, were observed. The mean diameter of the bifid and trifid mandibular canals was 2.2 mm and that of the main mandibular canal was 4.3 mm. Their mean length was 16.9 mm; the mean superior angle was $149.2^{\circ}$, and the mean inferior angle was $37.7^{\circ}$. Conclusion: Bifid and trifid mandibular canals in the Korean population were observed at a relatively high rate through a CBCT evaluation, and the most common type was the retromolar canal. CBCT is suggested for a detailed evaluation of bifid and trifid mandibular canals before mandibular surgery.

Purpose: The purpose of this study was to analyze articles published in the Journal of Korean Academy of Fundamental Nursing from 2001 to 2007. Method: Three hundred articles were analyzed using descriptive statistics. The focus was on research type, methodolgy and keywords. Results: Thirty percent of the research was supported financially. Ninety-four percent was quantitative research and of these the majority were surveys (73.2%). The rate of adoption for hypotheses in experimental studies were 55.07% but only 3% of the research included conceptual framework. The most common settings for data collection were clinical settings (51.99%), followed by community settings (43.71%). For data analysis, descriptive statistics (27.5%), t-test (17.1%), ANOVA (15.3%) and chi-square (7.9%) were most frequently used. Keywords were categorized into four nursing metaparadigms : human-beings, health, nursing, and environment. The most frequently used domain was health. Conclusion: The number of research papers published in the Journal of Korean Academy of Fundamental Nursing has increased and the quality has improved compared with articles published before 2001 year. Research topics varied and were mostly conducted on the basis of logical positivism.

Objectives: This study aimed to examine risk-accepting personality traits and associated factors among farmers. Methods: Data were collected from farmers aged over 40 living in Goryeong, North Gyeongsang-do Province, Korea. Study participants were enrolled in the Korean Rural Cohort study from 2011 to 2014. Surveys for the risk perception of farming were made through face-to-face interviews. Chi-square tests and logistic regression analysis were conducted adjusting for gender, age, marital status, and education. Results: Several factors such as gender, age, marital status, age first worked as a farmer, duration of farming, and history of pesticide poisoning were associated with risk-accepting personality traits among farmers. Farmers with risk-accepting personalities tend to be older, less educated, and have self-employed health insurance. Farmers who started farming after the age of 50 are likely to be risk averse compared to farmers who started farming before the age of 20 (OR=0.41, 95% CI; 0.21, 0.82). Frequent spraying of pesticides was marginally associated with higher risk acceptance among female farmers (OR=1.61, 95% CI: 0.99, 2.64). Male farmers who had experienced pesticide poisoning in their lifetime showed higher odds of risk-accepting personality traits (OR=2.20, 95% CI: 1.03, 4.72) Conclusion: Risk-acceptors were more likely to spray pesticides frequently and to experience more pesticide poisoning compared to risk-averse individuals. This result suggests that farming hazards are to some degree driven by risk-accepting personality traits. Further investigation of how risk-accepting behaviors influence farming practices and pesticide poisoning is needed.

Because the oral mucositis is often inevitable in acute leukemia patients during chemotherapy, the efforts must be made to keep these leukemia patients from oral mucositis. So we tried to develop two oral care protocols for reducing the level of oral mucositis during cytotoxic therapy through literature review and our clinical experience. This quasi-experimental study was performed to compare the prohpylatic value of these oral care protocols. Thirty-nine subjects were assigned to one of three groups. The first group performed bivon-normal saline gargling protocol, the second group performed chlorhexidine gargling protocol, and the last contrast group kept traditonal gargling protocol. The Oral Assessment Guide(OAG), the Beck's perception of oral comfort were used to assess oral status and subject's oral discomfort during chemotherapy. Each subjects were observed daily from the start of the chemotherapy until Absolute Neutrophil Count (ANC) reached $1,000/mm^3$. It continued about 2-4 weeks. The data was analyzed by ANCOVA and Kruskal-Wallis one way ANOVA, chi-sqare, survival analysis. The results were as follows : The contrast group showed significantly highest mean score of the OAG and Beck's perception of oral discomfort among three groups from second week to third week. However chie-test and survial analysis showed that the incidence of severe mucositis were not significantly different among three groups. Conclusively we recommend that nurses who care acute leukmia patients use bivon-normal saline gargling protocol be careful to occur severe mucositis during chemotherapy.

Failure of a pipeline due to local wall thinning is getting more attention in the nuclear power plant industry. Although guidelines such as ANSI/ASME B31G and ASME Code Case N597 are still useful fer assessing the integrity of a wall thinned pipeline, there are some limitations in these guidelines. For instance, these guidelines consider only pressure loading and thus neglect bending loading. However, most Pipelines in nuclear power plants are subjected to internal pressure and bending moment due to dead-weight loads and seismic loads. Therefore, an assessment procedure for locally wall thinned pipeline subjected to combined loading is needed. In this paper, three-dimensional finite element(FE) analyses were performed to simulate full-scale pipe tests conducted for various shapes of wall thinned area under internal pressure and bending moment. Maximum moments based on true ultimate stress(${\alpha}$$\sub$u,t/) were obtained from FE results to predict the failure of the pipe. These results were compared with test results, which showed good agreement. Additional finite element analyses were performed to investigate the effect of key parameters, such as wall thinned depth, wall thinned angle and wall thinned length, on maximum moment. Also, the effect of internal pressure on maximum moment was investigated. Change of internal pressure did not show significant effect on the maximum moment.
