Purpose: The purpose of this study was to explore practice-based evidence for health promotion in vulnerable populations with hypertension in primary health care settings. Methods: Two methodological procedures were adopted for this triangulation study. In the first phase, the sample was obtained from the computerized clinical data repository of a community nursing center. A total of 286 clients were assessed for hypertension as an actual circulation problem as coded in the Omaha System. In the second phase, a qualitative focus group was surveyed through semi-structured interviews conducted by nine advanced practice nurses who had been serving the hypertensive patients. Results: The community nurses provided essential primary healthcare services including health teaching guidance and counseling, and surveillance to vulnerable populations living in medically underserved community. There was a significant positive correlation between knowledge and behavior (r=.53, p<.01), between knowledge and health status (r=.40, p<.05), and between behavior and health status (r=.48, p<.01). Conclusion: This triangulation study encompassed not only quantitative findings from the computerized records of clients but also other information acquired from advanced practice nurses. This study contributes to understanding the importance of health promotion nursing interventions even with populations already diagnosed with chronic diseases such as hypertension.

For several decades, productivity in construction industry has been regressed and it is inevitable to improve productivity for major EPC players. One of challenges to achieve this goal is automatically extracting information from imaged drawings. Although computer vision technique has been advanced rapidly, it is still a problem to detect pipe lines in a drawing. Earlier works for line detection have problems that detected line elements be broken into small pieces and accuracy of detection is not enough for engineers. Thus, we adopted Contour and Hough Transform algorithm and reinforced these to improve detection results. First, Contour algorithm is used with Ramer Douglas Peucker algorithm(RDP). Weakness of contour algorithm is that some blank spaces are occasionally found in the middle of lines and RDP covers them around 17%. Second, HEC Hough Transform algorithm, we propose on this paper, is improved version of Hough Transform. It adopted iteration of Hough Transform and merged detected lines by conventional Hough Transform based on Euclidean Distance. As a result, performance of Our proposed method improved by 30% than previous.

Background: Urological cancers represent a major public problem associated with high mortality and morbidity. The pattern of these cancers varies markedly according to era, region and ethnic groups, but increasing incidence trends overall makes focused epidemiological studies important. The aim of the present study was to assess the incidence of most prevalent urological cancers in Iran from 2003 to 2009. Materials and Methods: The data for this study were obtained from the population-based Cancer Registry Center of the Iran Ministry of Health and Medical Education. Differences of mean age and age distributions of each cancer were compared between 2003 and 2009 in men and women. Results: Bladder cancer was the most common urologic cancer in both genders. The rate difference of age standardized ratio (ASR) of bladder and renal cell carcinoma in women were 1.54 and 2.01 percent per 100,000 population from 2003 to the 2009, respectively. In men, the rate difference of age standardized ratio of prostate, testis, kidney and bladder cancer was also 2.23, 1.2, 1.8 and 1.5 percent per 100,000 population from 2003 to 2009, respectively. The mean ages of patients in all cancers in both genders did not differ significantly through time (p value>0.05) but the distribution of ages of patients with bladder and prostate cancer changed significantly from 2003 to 2009 (p value<0.001). Conclusions: The results of present study suggest the general pattern and incidence of urological cancers in Iran are changing, the observed increase pointing to a need for urological cancer screening programs.

This is an underlying study for expanding child growth and developmental screening program, which had been implemented as a part of maternal child health service in a certain public health center located in P City. This study attempted to develop system model to discover, consult and follow-up developmental disabilities in children in early stage. For the purpose of providing groundwork for further development of screening program, the system model was analyzed and evaluated. One of the focuses of this study was developing practical tool that can aid small number staffs of public health center to handle large number of patients. 9 types of developmental checklist by key month was developed to support understaffed public health center. These checklists were also supplied to other public health centers, greatly improving qualitative and quantitative development of screening project. Also, the 4-step program of operating and managing child growth and developmental screening was proved to be quite effective. Total 632 children were evaluated and 21 of them were suspected to have developmental problem. Among these children, 8 children were determined to receive regular supervision of public health center. Other 13 children were recommended to visit professional institution, but only 7 of them actually visited institution. Four of these children who visited professional institution are currently receiving treatment, while the other 3 children were determined to require close observation. Five times of screening education were provided to the staffs in public health center and personnel in charge of children in every district public center in P City. The purpose of this training was to improve individuals' capability to implement project and to establish basis for expanding child growth and developmental screening program. The participants were guided to have continuous attention for the project, and their knowledge, skill and recognition were greatly improved through educational training. Also, professional child consulting and education, including lecture for baby food and baby food menu exhibition, were given to parents. Through this opportunity, parents acquired higher understanding about baby food while the local residents' recognition for maternal child health service was greatly improved.

Backgrounds: Obesity and depression are serious health problem and also constitute cardiovascular disease risk factors. Some studies found an association between obesity and higher rates of depression in women but not in men. The current study examined the association between depressive symptoms and obesity, especially central obesity in Korean women. Methods : The participants were 4,609 Korean women aged 20-85 years. Each individual was assessed for the presence of obesity and central obesity using the criteria suggested by WPRO(World Health Organization Regional Office for the Western Pacific). Depressive symptomatology was measured by Beck Depression Inventory(BDI). Results : In obese women, rate of depressed women is significantly higher compared normal group(27.6% VS. 23.2%, p<0.01). The rates of depressed women is higher in women who had central obesity(26.9% VS. 22.7%, p<0.01). Depressed women had higher rates of central obesity(93.2% VS.86.9%, p<0.01). Conclusion Our findings show obesity especially central obesity is associated with depressed women and suggests that further investigation for interaction between depression and obesity is needed.

Stroke is a health problem experienced by many elderly people around the world. Stroke has a devastating effect on quality of life, causing death or disability. Hemiplegia is clearly an early sign of a stroke and can be detected through patterns of body balance and gait. The goal of this study was to determine various feature vectors of foot pressure and gait parameters of patients with stroke through the use of a wearable sensor and to compare the gait parameters with those of healthy elderly people. To monitor the participants at all times, we used a simple measuring device rather than a medical device. We measured gait data of 220 healthy people older than 65 years of age and of 63 elderly patients who had experienced stroke less than 6 months earlier. The center of pressure and the acceleration during standing and gait-related tasks were recorded by a wearable insole sensor worn by the participants. Both the average acceleration and the maximum acceleration were significantly higher in the healthy participants (p < .01) than in the patients with stroke. Thus gait parameters are helpful for determining whether they are patients with stroke or normal elderly people.

This study was designed to investigate perception of job rotation and an organizational commitment of staff nurses working at K hospital and find the way of increasing an organizational commitment for the groundwork for efficient changes in the nursing staff. Data were collected from Aug. 20 to Aug. 28, 2004 through self reporting questionnaires taken by 318 nurses working at a hospital. The three structured instruments were used for collecting the data; Questionnaires for measuring the perception of job rotation, Questionnaires for measuring the utility and the problem of job rotation, and Mowday's Organizational Commitment Questionnaires. The Results were as follows : 1. 66.0% of 318 staff nurses approved of regular job rotation; 34.0% of them disapproved 34.3% of them wanted to get transferred to another department; 65.7% of them didn't. 2. Of general characteristics, age(F=17.469, P=.000), marital status(F=-2.781, P=.006), religion(F=5.688, P=.001), education level(F=8.816, P=.000), position(F=15.591, P=.000), a total clinical career(F=11.606 p=.000) and field in practice(F=4.206, P=.000) were significantly related to an organizational commitment. 3. There is relatively positive correlation between the perception of job rotation and an organizational commitment. In conclusion, the utility of on the job rotation and organizational commitment showed the positive correlation.

Highly aromatic (HA) oils are common processing aids used in tire tread compounds. However, they often bleed and evaporate from the vulcanizates during tire use. Thus, the mechanical and dynamical properties of the tire decrease. To overcome this problem, we investigated nonfunctionalized liquid butadiene rubber (LBR-305, Kuraray) and center-functionalized liquid butadiene rubber (C-LqBR), polymerized by anionic polymerization. In addition to the liquid butadiene rubbers, p-tert-octylphenol (P-Resin) and C5 hydrocarbon (H-Resin) tackifier resins, which can induce entanglement of rubber compounds, were researched as a processing aid to solve the bleeding problem. Liquid butadiene rubbers have significantly reduced extraction loss by crosslinking with the main rubber chain. They have also increased the abrasion resistance and showed similar or better mechanical and dynamical properties against HA oils. However, resin compounds did not show differences in extraction loss compared to HA oil compounds; instead, they showed increased wet traction.

Background : Even though tuberculosis (TB) is still a major public concern in Korea, there is little data on the management of TB patients and its outcomes in the private sector. This study evaluated the status of TB treatment in the private sector. Methods : Sixteen-hundred-sixty-six TB patients who were notified in a private university hospital from 2001 to 2002 were enrolled in this study. The patients were divided into pulmonary ($TB_P$), extrapulmonary ($TB_E$), and combined ($TB_{P+E}$) groups, and were also divided into initial and retreatment groups. The clinical characteristics, diagnostic methods, treatment regimens, and outcomes were analyzed and compared. Results : The mean age of the 1,666 patients was 48.9 years and the male-to-female ratio was 1.3:1. The number of patients in the initial and retreatment groups of $TB_P$, and those of ($TB_E+TB_{P+E}$) were 809, 276, 480, 101, respectively. A bacteriological study was performed in 92.0% of cases, and a positive culture was confirmed in 58.1% and 31.7% of patients with TBP and ($TB_E+TB_{P+E}$), respectively (p<0.05). The AFB smear was positive in 45.4 % of the $TB_P$ patients. PCR was carried out in 60.4% of the ($TB_E+TB_{P+E}$) group. The MDR was detected in 14.0% of isolates. Overall, the treatment completion, default, and death rates were 70.2%, 13.5% and 1.9%, respectively. Conclusion : Even though the management of TB patients in a private hospital was satisfactory in terms of the national guidelines, the high default rate was is still a problem. Efforts to decrease the default rate either independently or in cooperation with the public sector will be needed.
