Purpose: To assess gastric pH and its relationship with urease-test positivity and histological findings in children with Helicobacter pylori infection. Methods: Fasting gastric juices and endoscopic antral biopsy specimens were collected from 562 children and subjected to the urease test and histopathological examination. The subjects were divided into 3 age groups: 0-4, 5-9, and 10-15 years. The histopathological grade was assessed using the Updated Sydney System, while the gastric juice pH was determined using a pH meter. Results: The median gastric juice pH did not differ significantly among the age groups (p=0.655). The proportion of individuals with gastric pH >4.0 was 1.3% in the 0-4 years group, 6.1% in the 5-9 years group, and 8.2% in 10-15 years (p=0.101). The proportions of moderate and severe chronic gastritis, active gastritis, and H. pylori infiltration increased with age (p<0.005). Urease-test positivity was higher in children with hypochlorhydria (77.8%) than in those with normal gastric pH (31.7%) (p<0.001). Chronic and active gastritis were more severe in the former than the latter (p<0.001), but the degree of H. pylori infiltration did not differ (20.9% vs. 38.9%; p=0.186). Conclusion: Gastric pH while fasting is normal in most children regardless of age. Urease-test positivity may be related to hypochlorhydria in children, and hypochlorhydria is in turn related to H. pylori infection.

This study was performed to verify the effects of encapsulation against oil oxidation. Thiobarbituric acid (TBA) values of samples were compared during storage at $60^{\circ}C$, indicating that the encapsulated avocado oil had lower TBA values than the free avocado oil. Microcapsules consisting of a whey protein isolate (WPI)-only wall system had slightly improved oxidative stability; however, spray-dried particles containing a high proportion of maltodextrin (MD) clearly offered better protection from oxidation than the other forms of encapsulation. The chlorophyll (Chl) content of the encapsulated avocado oil was higher than that of the free oil sample. When compared to the control, all wall systems protected the change of the chlorophyll content storage. No large differences were observed between the encapsulated powders according to the various wall materials. The color of the encapsulated oil changed from green to yellowish-green, indicating the formation of pheophytin from chlorophyll. The yellowish color of the oil correlated with a reduced total Chl content. In conclusion, encapsulation with spray drying for avocado oil could lead to improved stability during storage with respect to oxidation and the preservation of chlorophyll.

Objectives : Little is known about the physician-related factors that are associated with the management of Hypertension. The purpose of this study was to determine the physician-related factors associated with blood pressure control in hypertensive patients. Methods : We surveyed 154 physicians at 117 public health (subhealth) centers in Gyeonggi-do, Forty-one physicians completed the survey (response rates : 26.6%) and 31 physicians were finally included as the study subjects. Using the information obtained from the self-reported survey, we measured the physician-related factors associated with hypertension control, including their perception of hypertension, prescription patterns (combination prescription rates, specific antihypertensives prescription rates among patients with diabetes mellitus), and sociodemographic factors. We then collected data on blood pressure and medication use in patients seen by these physicians from the health center#s information system. We compared the physicians# perceived hypertension control rates with the actual rates, and then evaluated the rate of high overestimation (overestimation by more than 25% of the median degree of hypertension control rate overestimation) among the physicians. The physicians# antihypertensive prescription patterns were also evaluated. Multiple logistic regression analysis was used to evaluate the independent association between hypertension control and physician-related factors. Results : The physicians tended to overestimate the proportion of their patients with controlled blood pressure (79.5% perceived vs. 57.8% actual). The percentage of physicians with high overestimation was 35.5% (11 physicians). The physicians with lower control rates were more likely to highly overestimate their patients# control rates. Physicians with below-median actual control rates tended to prescribe fewer combination treatments for patients with uncontrolled blood pressure and angiotensin-converting enzyme inhibitors or fewer angiotensin receptor blockers for patients with diabetes mellitus. The rate of high overestimation by physicians was 1.31 times higher in patients with uncontrolled blood pressure than in patients with other conditions (OR=1.31, 95% CI : 1.17-1.48). Conclusions : Physicians have a tendency to overestimate the rates of hypertension control in their patients. Because physicians have a direct role in treatment outcomes, physicians# overestimation about hypertension management contributes to inadequate blood pressure control. Thus, interventions for improving physician# awareness regarding the management of patients with hypertension are needed.

The development of histomorphometric and histodynamic investigations has permitted the description of a specific and complex osteopathy in hyperthyroidism. The increased bone turnover rate in hyperthyroid patients may be accompanied by a considerable bone loss. These features are associated with both inclosed osteoclastic bone resorption and increased osteoblastric bone formation, with an accelerated calcification rate. Conventional biochemical markers of bone metabolism, i.e. serum calcium and alkaline phosphatase and urinary hydroxyproline and calcium are normal in most patients with hyperthyroidism. However, the correlation between serum BGP and serum concentration of thyroid hormon suggests that serum BGP may be a sensitive marker of increased bone formation due to the hypersecretion of thyroid hormones. Any increase in bone turnover, whether focal or diffuse, will result in an increase in $^{99m}Tc-methylenediphosphonate$ uptake (MDP). The measurement of this uptake in hyperthyroid patients by bone provides a sensitive and objective means of quantifying skeletal metabolism. Using a standard shadow-shield whole-body monitor and radioimmunoassay kit, we have measured whole-body retention of $^{99m}Tc-MDP$ up to 24hr and concentration of serum Osteocalcin in 20 patients with hyperthyroidism and in 42 normals. The results were as follows; 1) The average of serum Osteocalcin level in 42 patients with normals was $9.90{\pm}4.87(ng/ml)$ and in 20 patients with hyperthyroidism was $19.54{\pm}5.7(ng/ml)$. Both the averages of serum Osteocalcin and 24hr $^{99m}Tc-MDP$ uptakes in hyperthyroid patients were higher than those in normals. 2) $^{99m}Tc-MDP$ uptakes in skeletal system increased in proportion to normal ageing after 40 yrs old in 42 patients with normals. The average of $^{99m}Tc-MDP$ uptakes in hyperthyroid patients were higher than those in normals without related ageing. 3) A significant relationships between the $^{99m}Tc-MDP$ uptakes and serum Osteocalcin level were peformed (r=0.55, $y=17.58+6.7\times$). From the above results we concluded that the measurement of serum Osteocalcin and 24hr $^{99m}Tc-MDP$ uptakes can be used for evaluation of bone turnover as a specific marker in hyperthyroid patients.

Anatomical and physiological studies of sink tissues are required for better understanding the biological plant growth system and energy metabolism Anatomy of root growth zones of two genotypes of tall fescue (Festuca arundinacea Schreb.) receiving 50 or 200 ppm N were determined, Cross-sectional anatomy and cells responses of root growth zones were observed and examined. Rapid radial root expansion occurred within the first 1.0 mm from root apex, and then increased gradually for both genotypes and N levels. Another increase in diameter occurred at high N after cell elongation slowed near 3.0 mm. Area of the central cylinder cell increased rapidly near the root apex. However, it then decreased again about 1.0 to 1.5 mm from the apex, perhaps because of pressure from the rapid increase of root diameter due largely to an increasing proportion of cortex and epidermis or hypodermis in the distal portion of the root growth zone. Root area from the apical initial to 6.0 mm distal consisted of 10 to 18% epidermis or exodermis, 67 to 79% cortex, and 10 to 22% vascular cylinder cells containing cambium cells (6 to 20%) and xylem cells (0.8 to 2.5%). These data indicate that N application affects root growth radially by increasing mainly cortex cell area, with less effect on epidermis and central cylinder cells.

This study is focused on guard major collegians who are composed of factor in medical emergency system. In the case of cardiac failure, it is to make its basic data develop its education program of CPR which can increase the patient's survival rate before his hospitalization. The subject of study is composed of 120 persons who are 94 boy-collegians(78.3%) and 26 girl-collegians(21.7%) in sex and 66 first-grade collegians(55.0%) and 54 second-grade collegians(45.0%) in a school year. There is significant difference in the practices of artificial respiration and the thorax pressure after the education of basic CPR in sex(p<0.01). The practices of artificial respiration in boy-collegians($93.72{\pm}4.21$) is higher than in girl-collegians($82.31{\pm}6.36$) and the practices of thorax pressure in boy-collegians($92.45{\pm}4.44$) is higher than in girl-collegians($88.08{\pm}6.49$). The satisfaction degree of boy-collegians($4.33{\pm}0.59$) is higher than that of girl-collegians($3.73{\pm}0.67$) after theory & practice education of basic CPR(p<0.01). It is necessary to develop the education program and educate its knowledge & technology in proportion to collegians characteristics of sex and school year. Also, education authorities should develop a subject of the accident provided the practical education of CPR for guard major collegians.

This study showed the national ecosystem classification for the spatial standards of ecosystems-based approaches to the risk assessments and adaptation plan. The characteristics of climate change risk assessment, implement national adaptation plans, and ecosystem/habitat classification status was evaluated. Focusing on the land cover classification widely utilized as spatial data for the assessments of biodiversity and ecosystem services in the UK and other countries in Europe, the applicability of the national land cover classification for climate change risk assessments was reviewed. Considering the ecosystem classification for climate change risk assessment and establishing adaptation measures, it is difficult to apply rough classification method to the land cover system because of lack of information on habitat trend by categorization. The results indicated that forest ecosystems and agro-ecosystem occupied 62.3% and 25.0% of land cover, respectively, of the entire country. Although the area is small compared with the land area, wetland ecosystem (2.9%), marine ecosystem (0.4%), coastal ecosystem (0.6%), and urban ecosystem (6.1%) can be included in the risk assessments. Therefore, it is necessary to subdivide below the medium classification for the forest and agricultural land, as well as Inland wetland, which has a higher proportion of habitat preference of taxa than land area, marine/coastal habitat, and transition areas such as urban and natural ecosystem.

The morphology changes of cadmium hydroxide into ${\gamma}$ phase by eletrolytes were carried out to improve the high rate charge and discharge efficiency of pasted cadmium electrodes. KOH solutions with different concentrations of NaOH were used as eletrolytes. It was found that the utilization of active material of cadmium electrode was the best in an electrolyte with 1.82 M NaOH. The amount of ${\gamma}-Cd(OH)_2$ increased in proportion to the concentration of NaOH. The surface area measurement showed that an active material which contained mainly ${\gamma}-Cd(OH)_2$ had a higher specific surface area than an active material of ${\beta}-Cd(OH)_2$. In a sealed cell, the discharge capacity was improved at high rate charge and discharge (1.0 C, 2.0 C) by using an electrolyte with NaOH. Furthermore, these improved performances were maintained up to 500 cycles at 1.0 C rate charge and discharge cycles.

Background: As the population is aging, chronic diseases and depression are becoming the main problems in a country's healthcare system. In this study, we aimed to explore the associations between chronic diseases and depression among the elderly in South Korea. Methods: We analyzed 9,975 (men, 4,147; women, 5,828) respondents obtained from the 2014 National Survey of Living Conditions and Welfare Needs of Korean Older Persons. Our dependent variable was either 1 or 0 according to whether a respondent had depression or not, where depression was defined when the Short Form of Geriatric Depression Scale score was 8 or more points. Variables of interest were 24 types of chronic diseases and covariates included various socio-demographic and health behavior characteristics. We performed Rao-Scott chi-square tests and hierarchal logistic regression analyses by gender, reflecting the characteristics of the survey. Results: A significant difference was found in the proportion of having depression between genders (men 18.9% vs. women 23.4%). According to fully adjusted, multivariable analyses, for elderly men, relative to those without any chronic disease, the odds ratio of depression was 1.56 (95% confidence interval [CI], 1.10-2.22) in the stroke patients group and 1.82 (95% CI, 1.01-3.25) in the osteoporosis patients group. For elderly women, the odds ratio was 1.96 (95% CI, 1.28-3.00) in the fracture/dislocation and aftereffects patients group and 1.30 (95% CI, 1.03-1.64) in the group of patients with other diseases. Conclusion: Even after being adjusted for diverse characteristics, some chronic diseases were significantly associated with depression in the elderly and the association differed between genders. Therefore, public health and medical interventions are needed to manage such chronic diseases together with curing depression symptoms.
