PURPOSE: This study aimed to contribute to overall public health by examining the prevalence rates of impaired fasting blood glucose and type 2 diabetes mellitus and developing a model to predict high risk factors for impaired fasting blood glucose and type 2 diabetes mellitus. METHODS: The 1998 Public Health Nutrition Survey data was used for this study. Subjects were 7,702 adult at the age of 20 or over. The frequency analysis, chisquared test was performed. A decision tree was utilized to define a model designed to predict high risk factors for impaired fasting glucose and type 2 diabetes mellitus. RESULTS: The prevalence rates of impaired fasting blood glucose was 10.8% and prevalence rates of type 2 diabetes mellitus was 9.4%. The decision tree analysis exhibited that age was strong factors for impaired fasting blood glucose. HDL cholesterol and kind of economic activities were high risk factors for impaired fasting blood glucose and type 2 diabetes mellitus on those in 20s. BMI, total cholesterol level, marriage status, sex for impaired fasting blood glucose and type 2 diabetes mellitus on those in 30s. The total cholesterol level, drinking and waist size were identified as risk factors on those in 40s. BMI, education level and hypertension seemed to have an impact on those in 50s. The waist size, sex and income had an impact on those in 60s. CONCLUSIONS: This study underscores the need for the public health infrastructure to improve various health promotion programs for those who have risk factors for impaired fasting blood glucose and type 2 diabetes mellius. The implementation of effective nutrition, workout and anti-drinking programs will boost public health.

PURPOSE: The purpose of this study was to investigate the anger expression types in nurses and to analyze the differences between the anger expression types and interpersonal problems. METHODS: The data were collected from 149 nurses working in general hospitals with 300 beds or more in Seoul or Gyeonggi province, Korea. For anger expression type, the anger expression scale from the Korean State-Trait Anger Expression Inventory was used. For interpersonal problems, the short form of the Korean Inventory of Interpersonal Problems Circumplex Scales was used. Data were analyzed using descriptive statistics, cluster analysis, multivariate analysis of variance, and Duncan's multiple comparisons test. RESULTS: Three anger expression types in nurses were found: low-anger expression, anger-in, and angerin/ control type. From the results of multivariate analysis of variance, there were significant differences between anger expression types and interpersonal problems (Wilks lambda F = 3.52, p < .001). Additionally, anger-in/control type was found to have the most difficulty with interpersonal problems by Duncan's post hoc test (p < .050). CONCLUSIONS: Based on this research, the development of an anger expression intervention program for nurses is recommended to establish the means of expressing the suppressed emotions, which would help the nurses experience less interpersonal problems.

The notion that obesity-induced inflammation mediates the development of insulin resistance in animal models and humans has been gaining strong support. It has also been shown that immune cells in local tissues, in particular in visceral adipose tissue, play a major role in the regulation of obesity-induced inflammation. Specifically, obesity increases the numbers and activation of proinflammatory immune cells, including M1 macrophages, neutrophils, Th1 CD4 T cells, and CD8 T cells, while simultaneously suppressing anti-inflammatory cells such as M2 macrophages, CD4 regulatory T cells, regulatory B cells, and eosinophils. Recently, however, new cell types have been shown to participate in the development of obesity-induced inflammation and insulin resistance. Some of these cell types also appear to regulate obesity. These cells are natural killer (NK) cells and innate lymphoid cells (ILCs), which are closely related, and invariant natural killer T (iNKT) cells. It should be noted that, although iNKT cells resemble NK cells in name, they are actually a completely different cell type in terms of their development and functions in immunity and metabolism. In this review, we will focus on the roles that these relatively new players in the metabolism field play in obesity-induced insulin resistance and the regulation of obesity.

The prevalence of obesity has increased alarmingly both worldwide and in Korea. This has also dramatically increased the prevalence of chronic obesity-associated diseases, including type 2 diabetes (T2D). Extensive studies on the molecular etiology of T2D have revealed several potential mechanisms by which obesity induces the development of insulin resistance and T2D. One of these is low-grade chronic inflammation. Studies hinting at the existence of this phenomenon were first published about 30 years ago. Ten years later, several seminal papers confirmed its existence, which then led to a rapid and massive escalation of research in this field. Today, the notion that obesity-induced inflammation mediates T2D is now well-accepted. This paper will review the key developments in this field, including the discovery that obesity-induced inflammation and insulin resistance is mainly regulated by adipose tissue-resident immune cells, particularly those in visceral adipose tissue. This review further details the research areas, including (1) the obesity-related factors that induce adipose tissue macrophage (ATM) inflammation, (2) the precise effector functions by which adipose tissue immune cells promote insulin resistance, (3) whether there are early immunological events that have an outsize effect on later events and could be targeted to arrest the development of insulin resistance, (4) the roles played by nonimmunological functions of ATMs and other immune cells, and (5) whether there are noncanonical immune responses to obesity (i.e., immune responses that are unique to obesity and cannot be detected by following the discoveries in the classical immunity field).

PURPOSE: The purpose of this study is to survey general and clinical characteristics of a group of relapsed patients with pulmonary tuberculosis, who are registered at a public health center in order to provide basic data for treatment of a patient's relapse, follow-up examination after the first treatment and health education. SUBJECT: Among 68 relapsed patients with pulmonary tuberculosis registered at two public health centers in Seoul from Jan, 1, 2002 to Dec. 31, 2002, 50 patients were selected as research subjects because they were contactable by telephone and they agreed to be a research subject. METHOD: The research carried out the structured questionnaire survey by telephone and surveyed research subjects' general and clinical characteristics, diseases except tuberculosis, drinking and smoking habit and knowledge about pulmonary tuberculosis treatment. Furthermore, the results of x-ray, whether a cavity existed or not, bacteriologic test, culture examination and drug resistance examination were examined and interval to relapse and history of dose attitude were surveyed. RESULTS: Among relapsed tuberculosis patients, male patients were 60% and they were more than women(40%). Patients over 60 were 42% most. In their occupation, 30% of them were unemployed and 50% of patients surveyed had monthly income below one million won. According to the findings in radiographic extent, most 50% of them were minimal, 44% were moderately advanced and 2% were far advanced. Patients who had cavity were 30%. According to the result in bacteriologic test, 54% showed positive smear pulmonary tuberculosis and 50.0% positive culture. According to the result in drug resistance, 24% showed drug resistance against one drug and 76% showed sensitive response. 46% had experienced medication side effects. According to interval to a relapse, 32% were relapsed less than 2 years, 14% less than 3-5 years and 54% more than 5 years. Average interval before a relapse were 11.6 years(11.6+/-11.15). There was a difference between their past regimen and their present regimen(P=0.001). The attitude towards taking a medication was assessed and they showed higher compliance with medication at present than in the past(P=0.001). In a case of smoking rate during treatment, the rate of non-smokers, who had been smokers, were higher(P=0.047). CONCLUSION: As a result, in order to prevent the disease from being relapsed and to increase the rate of treatment effectiveness, we need to make patients recognize the importance of regular follow-up examination and we should control thoroughly the patients. Furthermore, we need to provide them with more health education not to stop taking a medication earlier.

PURPOSE: This study was conducted to analysis the trends and states of suicide mortality in Korea from 1983 to 2001. METHODS: This study was based on data published in 1983-2001 from the annual report of the cause of death statistics of National Statistical Office. RESULTS: First, both of annual suicide rate and adjusted suicide rate rapidly went up in 1996 and hit the highest in 1998. Second, since 1983 only when the suicide rate was the highest in the ages 20-24 rather than other age groups, the suicides have been continuously shown to be the highest in the old age group. Third, the seasonal percentages of suicides were generally high in spring and summer, the seasons when the percentage of sunshine is relatively high, in both results for men and women. Fourth, men have most frequently committed suicide through hanging while their suicide through falling from a high site have least frequently occurred but currently tends to gradually increase. Meanwhile, women have most frequently done suicide generally by using insecticide. CONCLUSION: In Korea, the suicide rate and suicide percentage of the old people have been yearly increasing, and their suicide rate is also shown to the highest rather than those of other age groups. Therefore, it is necessary to prevent the suicide of the old people through a systematic analysis. Moreover, it is necessary to verify the risk factors and defensive factors for the suicide impulse and suicide attempt. On the basis of this, the construction of a nationwide social safety network for the national mental health is very important to find and treat the problems of the mental health to lead the people to suicide.

Lead, one of the most toxic heavy metals, takes longer time to be excreted from the body than other heavy metals. The purpose of this study is, by measuring lead excretion via urine and feces, to find out the effect of vitamin C in lead chelation. Thirty-six rats were randomly assorted into four groups. All 33 rats except for the control group were administered with lead, before orally administered with different doses of vitamin C per kilogram of body weight. The lead excretion levels in urine and feces as well as the survival rate were then measured for each group. The rats with lead administrations (10/13, 76.9%) with lead administrations only, 10/11 rats (90.9%) with lead administrations and low dose of vitamin C, 9/9 rats (100%) with lead administrations and high dose of vitamin C survived. Among the 29 surviving rats, low vitamin C intake group exhibited higher urinary excretion than the lead only group. The urinary excretion level in high dose vitamin C intakegroup was significantly higher than the lead only group. In addition, fecal lead excretion seemed to be increased in the high dose vitamin C intake group, compared to the group with lead administrations only with statistical significance. Through animal experiment, it was found out that administrating high dose of vitamin C accelerated the excretion of lead in body compared to low dose of vitamin C.
