This study was conducted to investigate the oral health related quality of life in elders concerning to residence at urban and rural. The subjects were 215 old persons who were over the 60 years old, living at Sahagu in Busan(113persons) and Geojer Si in Kyungnam (102persons). The data for this study were collected by direct interviewing method from May 30 th to June 30 th and September 12 th, 2005. Cushing & Sheiham's Sociodental Scale which measures oral health related quality of life was used for this study. The data were analysed by a computerized program named statistical package for social science including frequency, percentage, t-test. The results of this study were summarized as follows; 1. Mean score of the oral health related quality of life in elders is $2.42{\pm}1.03$ 2. There was a significant difference in oral health related quality of life in elders between the age 60 ~ 70 years group and the over than 71 years group(P < 0.01). 3. There was a significant difference in oral health related quality of life in elders between the urban and rural group(P < 0.05). Above findings suggest that further study about proper program for geriatric oral health evaluation is necessary in improving the oral health related quality of life in elders.
Background: Primary goal of anticoagulation treatment in patients with mechanical heart valve is the effective prevention of thromboembolism and safe avoidance of bleeding as well. Material and Method: Two-hundred and nine patients with the St. Jude Medical prosthesis operated on between 1984 and 1995, for mitral(MVR 122), aortic(AVR 39) and double mitral and aortic valve replacement(DVR 48) respectively, were studied on the practically achieved levels of anticoagulation and the clinical outcomes. Patients were on Coumadin and followed up by monthly visit to outpatient clinic for examination and prothrombin time measurement to adjust the International Normalized Ratios(INRs) within the low-intensity target range between 1.5 and 2.5. Result: A total anticoagulation follow-up period was 1082.0 patient- years(mean 62.1 months) and INRs of 10,205 measurements were available for evaluation. The accomplished INRs among the replacement groups were not significantly different and only 65% of INRs were within the target range. And, in individual patients, only 37% of patients had INRs included within the target range in more than 70% of tests during follow-up period. The levels of INRs in patients with atrial fibrillation, which was found in 57% of patients, were definitely higher than the ones measured in patients with regular rhythm(p<0.001). Thromboembolisms were experienced by 15 patients with the incidence of 1.265%/patient- year(MVR 1.412%, AVR 0.462% and DVR 1.531%/patient-year) and major bleeding by 4 patients with the incidence of 0.337%/patient-year(MVR 0.424%, AVR none and DVR 0.383%/patient-year). Frequent as well as prolonged missing of prothrombin time tests was the main risk factor strongly associated with the thromboembolic complications(odds ratio 1.99). The proportion of INRs within target range of less than 60% in individual patient was the highly significant risk factor of both thromboembolic and overall embolic and bleeding complications(p<0.004 and p<0.002 respectively). Conclusion: In conclusion, the low-intensity therapeutic target range of INRs was adequate in patients with AVR and in sinus rhythm. However, the patients with replacement of the mitral valve were more likely to require higher target range of INRs, especially in the presence of atrial fibrillation, to achieve the practical levels of anticoagulation enough to prevent thromboembolic complications effectively. For the higher therapeutic target range of INRs between 2.0∼3.0, further accumulation of clinical evidences are required. It is highly desirable to improve the patients' compliance under continuous instructions in visiting outpatient clinic and in taking daily Coumadin without omission and to keep INRs consistently within optimal range with tight control for minimization of chances and of periods of exposure to the risk of complications. And, particularly, patients with high risk of complications and with wide fluctuation of INRs should be better managed with frequent monitoring anticoagulation levels.
This study was conducted to compare the date on knowledge, attitude and motivation toward blood donation between donors and nondonors. The study population included 622 donors and 322 nondonors who visited the mobile blood donation car of Taegu Red Cross Blood Center and participated the group appointed blood donation campaign managed by the center from March 1 to March 31, 1989. The donors and nondonors were questioned above mentioned items with a formulated questionnaire. Among the general characteristics of the subjects in the study, male predominace(84.1% in donors and 73.6% in nondonors) in young age group (16-24 years) was the outstanding feature. As a medium of information about blood donation, "television" was playing a dominant role(donors ; 75.2%, nondonors ; 78.9%), while "magazine"played more important roles among donors. Of the donors, 70.6% and of the nondonors, 58.1% replied that they had ever been induced to donate blood (p<0.01). Major inducers were friend and personnel of mobile blood donation vehicle. On the measuring of knowledge level, the average rates of correct answer was higher in donors (62.6%) than in nondonors (54.1%) (p<0.01). Higher the education level was presented, higher the knowledge level (p<0.05). There have been noticeable difference between donors and nondonors in blood replying the questionnaire set to measure their attitude toward blood donation. especially in the items such as "impression toward blood", "selection of transfusion blood source" and "view on the situation of blood shortage." The major motivation toward blood donation of the groups were "possible future need" and "altruism or humanitarian interest". The major reasons for not donating blood in both groups were "fear of the needle" and around to visit to mobile car or center."
Purpose : This study assessed the improvement of competency levels for participants, as well as their satisfaction from completion of the special international disaster response program. Methods : The program structure followed an intensive two-week course that included a combination of lectures, discussions, case studies, and field trips. "ICN Framework of Disaster Nursing Competencies" was used for designing the program. A pre-post survey was done to measure the change in the competencies of students and assess their satisfaction after finishing the program. Focus group interviews were also performed to further understand the attitudes of participants toward the disaster issues. Results : The overall pre-program test score for disaster competency was $2.18{\pm}0.68$ and the post-program test score was $6.30{\pm}0.84$, which showed statistically significant gains in all competency items (p <.001). The general satisfaction of participants with the program was quite high, demonstrated by a mean score of $4.5{\pm}0.51$. The benefits for students from program participation included increased knowledge and better understanding of the important roles of international organizations and NGOs. Conclusion : The international disaster education programs are necessary to provide an opportunity for students to increase their disaster competency. In addition, future development of a unified educational competency framework is also necessary.

Macrobenthos species-area relationship was investigated and empirical models were estimated to enable comparisons among species numbers of different sample size. The study aims to choose a way to predict cumulative relative species number (CRSN) in a given sample size Saemangeum, located in the west coast of South Korea, were visited in Apr., May and Aug.,2002 and a total of 261 biological samples from 87 stations were obtained by employing a quantitative sediment sampler, Smith-McIntyre grab and design of 3 replicates at each station. Relative species numbers (%) were baselined at sample size of 1000 $\textrm{cm}^2$ and the patterns of CRSN along the axis of sample size were measured and observed. In correlation analysis performed on a set of abiotic and biotic variables, log-transformed CRSN showed the only significant relationship with log-transformed density. Based on the result, three models, Log CRSN 2000, Log CRSN 3000 and Log CRSN were produced. The former two were devised to predict CRSN at 2000 and 3000 $\textrm{cm}^2$ respectively, and the latter at various sample sizes and samplers (all p-values were <0.001). Database from other studies (intertidal or subtidal macrofaunal samples from Kyonggi Bay and Saemangeum) were used to evaluate validity of the models. Observed CRSN below sample size of 3000 $\textrm{cm}^2$ fell under the range of 95% prediction interval and this was appeared to provide reliability of the models below that sample size.

In this paper a scalable QoS-based hierarchical inter-domain routing scheme for distributed multimedia applications in a high speed wide area network. The problem of QoS-based routing is formulated as a multicriteria shortest path problem, known as NP-complete[21,30]. Our routing scheme consists of two phases. In Phase 1, two graph construction algorithms are performed to model the network under consideration as a graph. The graph contains a part of the network topology which is completely neglected or partially considered by existing routing schemes, thus maintaining more accurate topology information. In Phase 2, a heuristic call-by-call algorithm is performed for selecting a feasible path efficiently in depth first search-like manner on the graph and tailoring to each application's QoS requirements, beginning at a vertex that represents the source node. In this paper, a simple rule is also produced, by which the visiting order of outgoing edges at each vertex on the graph is determined. The rule is based on each edge's the minimum normalized slackness to the QoS requested. The proposed routing scheme extends the PNNI-type hierarchical routing framework. Note that our routing scheme is one of a few QoS-based hierarchical routing schemes that address explicitly the issue of selecting a path with multiple metrics.
The purpose of this study is to secure the basic data for the physical environment of an eco-friendly restaurant by surveying and analyzing customer perceptions of the servicescape of an eco-friendly restaurant and to verify the organic causation of the servicescape of an eco-friendly restaurant and customer perceived value, attitude and behavior intention. The samples for empirical analysis were selected from the customers over 20 years who lives in Seoul and Kyung-gi suburbs have experienced visiting eco-friendly restaurant or green restaurant more than once a month. Total 300 copies of questionnaire were distributed for the survey from the second day to the fifteenth day of April for 14 days, and total 264 (88.0%) copies of survey questionnaire except for some questionnaires that had much strong lean tendency or the missing value was discovered. The research results are as follows; when a customer recognizes an eco-friendly restaurant favorably, he or she considers that servicescape plays an important role in deciding perceived value through tangible and intangible perceived values. Since, customer perceived value has a positive effect on attitude and behavior intention, the customer considers as affected on his/her behavior intention when satisfied with the eco-friendly restaurant, which is considered that positive customer attitude will have an effect on behavior intention. Thus, it is considered based on this in-depth analysis result that maintaining and providing servicescape of high standard in the manager's perspective will have a direct effect on ensuring tangible outcomes.
This research basically work on oral health condition of the diabetes patients with data from 2006 National oral Health Survey. Based on this data, this research will provide basic materials about developing program with necessity of Recognition and education of the oral health condition. Analysis with using SPSSWIN 12.0 makes some results on the below. First, Existence and nonexistence based on age division shows result that over 70 years old gets 39.8%, which is highest percentage(p<0.05). Second, In existence and nonexistence based on sex distinction and age division, Women gets higher percentage (60.8%) than percentage of the men (39.2%). Third. Both diabetes patient and control group answered 'unhealthy' about subjective recognition of the oral health condition. Forth, percentage of caries on permanent tooth 12 92.0% for diabetes patient (p<0.05). Fifth, Answer about periodontal structure of diabetes patient is 88.9% of blooding periodontal structure(p<0.05). Sixth, Result of the demand of caries and periodontal structure treatment from diabetes patients show that diabetes patient does not feel necessity about treatment although they gets hardship of chewing. Also, it does not show any statistical difference. Seventh, Results of the oral health practice based on demographic characteristics are eating snack(highest answer). Latest visiting dental hospital before 1 year ago, or long before this. Frequencies of brushing tooth are less than 3 times. Also, il does not show any statistical difference.
With the growth of the food-catering industry, consumer preferences and the number of dine-in restaurants are gradually increasing. Thus, personalized recommendation services are required to select a restaurant suitable for consumer preferences. Previous studies have used questionnaires and star-rating approaches, which do not effectively depict consumer preferences. Online reviews are the most essential sources of information in this regard. However, previous studies have aggregated online reviews into long documents, and traditional machine-learning methods have been applied to these to extract semantic representations; however, such approaches fail to consider the surrounding word or context. Therefore, this study proposes a novel review textual-based restaurant recommendation model (RT-RRM) that uses deep learning to effectively extract consumer preferences from online reviews. The proposed model concatenates consumer-restaurant interactions with the extracted high-level semantic representations and predicts consumer preferences accurately and effectively. Experiments on real-world datasets show that the proposed model exhibits excellent recommendation performance compared with several baseline models.

Objective: This study was performed to explore the effectiveness of community organization as a strategy for health promotion. Methods: We used data from community health interviews from 6 administrative sections (eup, myeon, or dong) with high mortality from August to October, conducted once in both 2010 and 2013 as part of the Health Plus Happiness Plus Projects based on the concept of community empowerment in Gyeongsangnam-do Province. For 2010, the study subjects comprised a systematic sampling of 220 adults from each of the six sections for a total of 1320 subjects, and for 2013, 200 from each section for a total of 1200 subjects. We compared main health behavior indicators and empowerment score between these two years. Results: Smoking prevalence in men was 47.4% in 2013, and 47.7% in 2010, respectively. Prevalence of walking 5 days or more per week was 35.6% in 2013, significantly lower than 46.2% in 2010. Also, during that period, both biennial health examination rate and biennial gastric cancer screening rate among those 40 years of age and over significantly increased from 57.7% to 63.6% and from 49.3% to 55.0%, respectively. Mean empowerment score at the community level significantly increased from 12.6 to 14.0. Conclusions: This study suggests that the three-year implementation of community organization might have helped to increase the participation rate of biennial health examinations including cancer screenings in the community. However, this was not the case for smoking cessation and walking. Further studies are needed for evidence-based health promotion.
