To assess the association between oral health and general health, this study examined the relationship between chewing difficulty and twelve chronic health conditions such as hypertension, hyperlipidemia, diabetes, cerebro- and cardiovascular disease, musculoskeletal disease, respiratory disease, eye/nose/throat disease, stomach/intestinal ulcer, renal dysfunction, thyroid disease, depression, and cancer in Korea. The study population was 3,066 elders aged 65 years old and more from the fourth Korean National Health and Nutrition Examination Survey. Chewing difficulty was measured on a 5-point Likert scale. Chronic conditions were assessed by self-reported questionnaire. Confounders were age, gender, education, income, smoking, drinking, and obesity. Chi-square test, general linear model, and multiple logistic regression model were done with complex sampling design. Musculoskeletal disease (adjusted odds ratio=1.33), respiratory disease (adjusted odds ratio=1.52), and cancer (adjusted odds ratio=1.58) were independently associated with chewing difficulty. Multiple chronic conditions with more than 4 chronic disease showed significant association with chewing difficulty (adjusted odds ratio=1.37).

The code of the International Classification of Disease(ICD) is seriously questioned on its effectiveness in identifing an independent disease entity from similar conditions at general practitioner's offices. This study has attempted to show individual coding variations in ICD for similar ambulatory care conditions. It has been assumed that a following outpatient visit is regarded as the sane kind of visit owing to the same disease if a visit to the different source of care would be mad within an interval of less than two days. The 'D' health insurance association was selected for this analysis. The 'D' association had 153,298 members and made claims of 642,605 outpatient care in 1990. Out of the total outpatient claims, 8.6%(55,102 claims) were counted as the same disease which could meet the above assumption. Percent of conditions classified as the 10 leading causes of frequent visits which were matched accurately to the subsequent ICD diagnostic code found to be 15.8% on the average. The URI was noted for the highest concurrence rate of 20.4%. This proportion was even decreased to 11.6% on the case of chronic disease. Despite the fact that the assumption underlying the definition of the above same disease is rather rough and inappropriate, this study reveals that the code of ICD currently in use has weaknesses in seperating a certain independent disease from similar conditions at the outpatient setting. Thus, efforts need to be elaborated to meet the need of a new system of classification for conditions and diseases encountering at ambulatory care.

This study is aimed to clarify on the influence of cultivated conditions and fungicides on development of Rhizoetonia diseases of zoysiagrass and creeping bentgrass and results are as follows. Infection rates of disease were observed more serious when inoculum amounts were higher than low. Effects of the watering intervals on the severity of disease with artificial inoculating conditions, infection rates were higher when two days watering interval for creeping bentgrass and one day interval for zoysiagrass. Disease severity of creeping bentgrass incited by Rhizoetonia solani AG 1 (1A) was grater under conditions of double amounts of nitrogen fertilization. A posi- tive correlation was founded between the pH and disease development. The pots with pH 5 and 8 were significantly more diseased grass than those in which the pH was in 6.5. Mepronil and myclobutanil were extremely effective against brown patch of creeping bentgrass and large patch of zoysiagrass and followed by capro, and tebeonazole. Fenari was inferior effect to both diseases.

Crop yield is critically related to the physiological responses and disease resistance of the crop, which could be strongly affected by high temperature conditions. We observed the changes in the growth of barley under higher than ambient air-temperature conditions using a temperature gradient field chamber (TGFC) during winter and spring. Before the stem extension stage of barley growth, Cladosporium sp. spontaneously appeared in the TGFC. The severity of disease became serious under warmer temperature conditions. Further, the stomata closed as the severity of the disease increased; however, stomatal conductance at the initial stage of disease was higher than that of the normal leaves. This was likely due to the Iwanov effect, which explains that stressed plants rapidly and transiently open their stomata before longer-term closure. In this study, we tested three optical methods: soil-plant analysis development (SPAD) chlorophyll index, photochemical reflectance index (PRI), and maximum quantum yield (Fv/Fm). These rapid evaluation methods have not been used in studies focusing on disease stress, although some studies have used these methods to monitor other stresses. These three indicative parameters revealed that diseased barley exhibited lower values of these parameters than normal, and with the increase in disease severity, these values declined further. Our results will be useful in efficient monitoring and evaluation of crop diseases under future warming conditions.

Investigating the existence of volume-outcome relationships for specific disease groups relates directly to the policy issue of whether, and how, specific inpatient services should be regionalized. This study examined whether medical costs and lengths of stay as outcomes were affected by changes in volume within hospitals. Based on the claims data obtained from National Federation of Medical Associations, each six disease categories from medical and surgical conditions were selected and 29,720 cases from 1,266 hospitals were analyzed. Main findings of the research can be summarized as follows: 1. Analyzing volume and cost per case relationship, tonsillectomy class 1, hernia procedure class 0, appendectomy and cesarean section class 0,1 in surgical conditions showed negative relationship significantly. In cases of medical conditions, costs per case in respiratory neoplasm class 2, COPD class 1, 2, digestive malignancy were also related to volume negtively. 2. Comparing volume with length of stay per case, lens procedure class 0, hernia procedure class 0, appendectomy class 0,1, cesarean section class 1 in surgical conditions showed negative relationships significantly. In medical conditions, volume of respiratory neoplasm class 2, COPD class 1,2, digestive malignancy class 0 were associated with negatively. 3. Within same disease categories, changes in cost and length of stay per case to volume were more remarkable in severe cases. These results suggested a significant inverse relationship between disease cases and cost, length of stay per case as outcome variables.

Armillaria root disease affects forests around the world. It occurs in many habitats and causes losses in the infested stands. Weather conditions are important factors for growth and development of Armillaria species. Yet, the relation between occurrence of damage caused by Armillaria disease and weather variables are still poorly understood. Thus, we used generalized linear mixed models to determine the relationship between weather conditions of current and previous year (temperature, precipitation and their deviation from long-term averages, air humidity and soil temperature) and the incidence of Armillaria-induced damage in young (up to 20 years old) and older (over 20 years old) coniferous stands in selected forest districts across Poland. We used unique data, gathered over the course of 23 years (1987-2009) on tree damage incidence from Armillaria root disease and meteorological parameters from the 24-year period (1986-2009) to reflect the dynamics of damage occurrence and weather conditions. Weather parameters were better predictors of damage caused by Armillaria disease in younger stands than in older ones. The strongest predictor was soil temperature, especially that of the previous year growing season and the current year spring. We found that temperature and precipitation of different seasons in previous year had more pronounced effect on the young stand area affected by Armillaria. Each stand's age class was characterized by a different set of meteorological parameters that explained the area of disease occurrence. Moreover, forest district was included in all models and thus, was an important variable in explaining the stand area affected by Armillaria.

벼 품종 Brazos와 M-201의 도열병에 대한 단위시간당 감염속도와 점접종원으로 부터의 단위 거리당 확산경사는 밭논과 물논의 두 재배조건에 따라 크게 달랐다. 물논재배는 도열병의 감염속도를 늦추고 확산경사를 완만하게 하였다. 점접종원으로부터 거리별로 4지점에서 측정된 도열병의 감염속도는 거리에 따른 통계적인 유의차는 없었지만 점접종원으로부터의 거리가 멀어짐에 따라 빨라지는 경향이었다. 품종별 감염속도는 Brazos보다 더 이병성인 M-201 품종에서 높았고 확산경사도 M-201 품종에서 가파른 경향이었다. 그러나 도열병이 진전함에 따라 생성된 이차전염원 때문에 도열병 확산경사는 두 품종에서 모두 완만해졌다. 조사된 확산형사의 두 경험적 모델 중에서 Kiyosawa와 Shiyomi 모델이 Gregory 모델에 비하여 통계적 적합성이 높았다. 밭상태에서 단위시간당 도열병 isopaths 이동거리는 Brazos와 M-201 품종에서 각각 0.2m/일와 0.4m/일로 측정하였다. 이상의 결과, 도열병에 대한 품종저항성의 차이는 감염속도뿐만 아니라 확산경사의 측정에 의하여 효과적으로 감지될 수 있다고 생각된다.

Purpose: The purposes of this study was to describe the lived experience structures of married immigrant women with chronic diseases in reorganizing their lives in a variety of situations and contexts. Methods: This study applied grounded theory approach, and the participants were 15 married immigrant women with chronic disease. Data were collected through individual in-depth interviews and then analyzed by the method in Strauss and Corbin (1998). Results: The extracted data were organized 41 concepts, 21 subcategories, and 8 categories. The central phenomenon was determined to be "Life turned into a chronic disease." The causal conditions were "Undergoing physical and mental stress from marriage", "Lack of information on chronic diseases." The extracted contexts was "The demand for health resources." action and interaction strategies, "Finding problems and solutions." The intervention conditions influencing the strategies was "Establishing a support system." The result of such action was "To settle down in a way of life that suits your conditions." Conclusion: By providing a comprehensive and integrative understanding of how married immigrant women with chronic disease reorganize their lives, the study is expected to contribute to the development of social systems and national policies.

Pediatric onset Crohn's disease (CD) tends to have complicated behavior (stricture or penetration) than elderly onset CD at diagnosis. Considering the longer duration of the disease in pediatric patients, the accumulative chance of surgical treatment is higher than in adult onset CD patients. Possible operative indications include perianal CD, intestinal stricture or obstruction, abdominal abscess or fistula, intestinal hemorrhage, neoplastic changes and medically untreatable inflammation. Growth retardation is an operative indication only for pediatric patients. Surgery can affect a patient's clinical course, especially for pediatric CD patient who are growing physically and mentally, so the decision should be made by careful consideration of several factors. The complex and diverse clinical conditions hinder development of a systemized treatment algorithm. Therefore, timing of surgery in pediatric CD patients should be determined with individualized approach by an experienced and well organized multidisciplinary inflammatory bowel disease team. Best long-term outcomes will require proactive post-operative monitoring and therapeutic modifications according to the conditions.
