Objectives: This study aimed to examined the socioeconomic disparities in oral health related behaviors and to assess if those behaviors eliminate socioeconomic disparities in oral health in a nationally representative sample of adults aged 30-64. Methods: Data are from the Korea Third National Health and Nutrition Examination Survey (2005). Behaviors were indicated by smoking, over intake of daily calories from carbohydrate, perceived stress, frequency of daily tooth brushing, use of oral hygiene goods, insufficient oral treatment. Oral health outcomes were self-reported dental caries and periodontitis during the last 12 months and perceived oral health. Education, household income, and employed status indicated socioeconomic position. Sex, age, residential area, marital status were adjusted for in the logistic regression analysis. Logistic regression analysis was used to assess socioeconomic disparities in behaviors. Logistic regression model adjusting and not adjusting for behaviors were compared to assess the change in socioeconomic disparities in oral health. Results: Clear socioeconomic disparities in all behaviors were showed. After adjusting for behaviors, the association between oral health and socioeconomic indicators attenuated but did not disappear. For example, the odd ratios of reporting poorer oral health for persons in no education or elementary school education and middle school education groups, compared with college or higher education group, were 1.77 (95% CI: 1.36-2.29) and 1.56 (1.19-1.97), respectively. After adjusting for all indicators of behaviors, these odds ratios attenuated to 1.54 (1.17-2.03) and 1.48 (1.15-1.91) for those groups, respectively. Conclusion: These findings suggest that the presence of more complex determinants of socioeconomic disparities in oral health should be considered with developing preventive policies for those disparities.

The main purpose of this study was to examine the effects of maternal achievement pressure and emotional support on adolescents' achievement motivation. A total of 241 adolescents in the second grade of two middle schools in Seoul and their mothers participated in the study, and completed questionnaires on mothers' achievement pressure and emotional support. Adolescents also answered a questionnaire on achievement motivation. Sohn's(1997) Achievement Pressure Scale, Sung's(1993) Social Support Scale and Hermans'(1970) Prestatie Motivatie Scale were used for this survey. Data were analyzed by Pearson's correlation coefficients, t-tests, regressions, and one-way ANOVA with Duncan's multiple range tests. Results showed that maternal achievement pressure and emotional support and adolescents' achievement motivation did not vary as a function of sex. Maternal achievement pressure and emotional support had positive effects on achievement motivation of adolescents, and maternal achievement pressure played a more influential role on the motivation of adolescents than emotional support. Among four groups divided by the level of maternal achievement pressure and emotional support, high/high, high/low, low/high, and low/low, adolescents in the high/high group were perceived to have the highest achievement motivation. Findings suggest that both maternal achievement pressure and emotional support are important in improving adolescents' achievement motivation.

Purpose: This study aimed to investigate the outcomes of laparoscopic gastrectomy in very elderly patients with gastric cancer, who have outlived the average lifespan of the Korean population (men: ${\geq}77years$, women: ${\geq}84years$). Materials and Methods: Between 2004 and 2015, 836 patients with gastric cancer underwent a laparoscopic gastrectomy. They were divided into the elderly group (EldG) and non-elderly group (nEldG). Propensity score matching for covariates of sex, tumor depth, node status, and extent of resection was performed. Clinicopathologic characteristics, and surgical and survival outcomes were compared between the 2 groups. Results: The EldG had a higher American Society of Anesthesiologists (ASA) score and a higher number of comorbidities. There was no significant difference in the post-operative complications, except for pulmonary complications, which were more frequent in the EldG (5/56, 8.9%) than in the nEldG (0/56, 0%). The EldG had a shorter overall survival (OS), but cancer-specific survival was similar for both groups. Among deceased patients, 2 (25%) and 8 patients (50%) died within a year of surgery in the nEldG and EldG, respectively. Univariate and multivariate risk factor analyses for OS showed that age, ASA score, tumor, node, metastasis (TNM) stage, and occurrence of complications were significantly related to deterioration in OS. Conclusions: Laparoscopic gastrectomy can be safely performed in very elderly patients with gastric cancer who have outlived the average lifespan of the Korean population. However, impact of laparoscopic gastrectomy on improving survival is not clear, and careful patient selection is recommended.

Whole-body insulin resistance results largely from impaired insulin-stimulated glucose disposal in skeletal muscle. Our previous studies using differential display and quantitative real-time RT-PCR have shown that a novel cDNA band (DD23) had a higher level of expression in insulin resistant skeletal muscle and it was correlated with whole-body insulin action, independent of age, sex, and percent body fat. In this study, we cloned and characterized DD23. The DD23 sequence is part of the 3'UTR region of the RNA binding motif, single stranded interacting protein (RBMS3). We have cloned the full length cDNA for RBMS3 and identified two splice variants. These variants named DD23-L and DD23-S have 15 and 14 exons respectively and differ from RBMS3 in the 3'UTR significantly. Northern blot analyses showed that an ~8.8 kb mRNA transcript of DD23 was predominantly expressed in skeletal muscle and to a lesser extent in placenta, but not in heart, brain, lung, liver, or kidney, unlike RBMS3. Elevated expression levels of these novel alternatively spliced variants of RBMS3 in skeletal muscle may play a role in whole body insulin resistance.

Object : Nerve growth factor(NGF) is a protein involved in neuronal survival and plasticity in the central nervous system, which might play an important role in stress, depression and suicide. This study was performed to determine whether there is an alteration in plasma NGF concentrations in depressed patients with suicidal attempt. Methods : The subjects were 32 depressed patients who attempted suicide and admitted in emergency room. Forty-four hospitalized non-suicidal depressive patients and the 30 normal controls were closely matched with the suicidal group in terms of age and sex. Individuals in all 3 groups were evaluated independently by a semi-structured interview for the purpose of establishing a DSM-IV criteria diagnosis. The severity of depressive symptoms was evaluated using Hamilton depression rating scale(HDRS). The severity of the suicidal behavior was evaluated by Weisman and Worden's risk-rescue rating(RRR) system and the Lethality Suicide Attempt Rating Scale(LSARS). Plasma NGF level was measured by the enzyme linked immunosorbent assay(ELISA) method. Results : There were no statistically significant differences of the plasma NGF levels among groups. LSARS and RRR did not reveal any significant correlation with ${\beta}$-NGF level in suicidal depressive patients. Conclusion : This study do not support an association between ${\beta}$-NGF and suicidal depression. However it is necessary to investigate this association through other route such as postmortem brain.

Advertisements provide consumers with in-formation and knowledge about products and help a society to sustain homogeneity by actively reflecting important characteristics of mass culture. Yet this reflection is a selective and purposeful representation by the party of the fashion manufactures and carries the intention of stimulating and augmenting desire for commodities aiming to perpetuate capitalism. This study understood this selective reflection of mass culture by advertisements as a feature of hegemonic struggle between/fashion business and consumers and defined the values selected by advertisements as ideologies supporting the consumption ideology of capitalism. The purpose of this study was to examine the contents of the ideologies expressed in the clothing advertisements in women's magazines to persuade consumers into consumption. The method of study was mainly qualitative with subsidiary citations from the results of content analysis. The objects of analysis were clothing advertisements in 1996 issues of CeCi and Woman Sense, which were identified as the two most popular women's monthly magazines. The ideologies identified were ideologies concerning (1) Self Identity, (2) Sensibility, (3) Sex Role, (4) Globalism, (5) Youth, (6) Leas-ure and Pleasure. Repeated and insisted as natural and true, there values were proposed to be believed as common senses and studies re-port that values of advertisements are ac-cepted as more readily as they are more unreasonable, and the acts and behaviors expres-sed within advertisements are often imitated in real life situations. Therefore, it is highly probable that these values emphasized within advertisements are enacted in thoughts and behaviors of consumers' real life. Accordingly the author suggests that critical interpretation of advertisements is seriously required to fully understand the commodity ridden post industrial society of today and to lead a subjective life within it.

Objectives: Over the past several years, the incidence of hepatitis A infection has been increasing rapidly in the young-adult population in Korea. We examined the effects of area-level socioeconomic status and environmental hygiene on the incidence of hepatitis A. Methods: This study is based on the registered national population of Korea and the national health insurance data from 2004 to 2008. A total of 73 459 individuals were confirmed to have had hepatitis A. The standardized incidences of hepatitis A in 232 districts adjusted for sex and age of people were calculated for each year, and the rate ratios of the incidence rates were estimated according to area-level socioeconomic status and environmental hygiene using multiple Poisson regression models. Results: The incidence rates of hepatitis A infection were 15.6 (per 100 000) in 2004, 19.0 (per 100 000) in 2005, 27.2 (per 100 000) in 2006, 25.1 (per 100 000) in 2007, and 61.7 (per 100 000) in 2008. The analysis of the area-level effects showed that residential areas of the less deprived than other regions, areas with higher levels of education, and heavily populated areas were significantly associated with increased risk. Conclusions: There is a very strong possibility that both area-level socioeconomic status and environmental hygiene play a role in increasing the risk of hepatitis A infection in Korea. Therefore, to reduce hepatitis A infection, we need a nationwide strategy that considers these area-level characteristics.

Purpose: Many studies have shown that regular exercise produces positive effects on health. The purpose of this study was to examine the differences of health-related quality of life by stage of exercise and the interaction effect of age, sex and stage of exercise. Method: A total of 1266 participants were interviewed with structured questionnaire. Stage of exercise was assessed with a single item and respondents were classified with respect to exercise intention and behavior. Health-related quality of life was measured with SF-36 Health Survey Questionnaire. Result: Health-related QOL were found to be different by stage of exercise. The subjects who were reached maintenance stage showed significantly higher scores on physical functioning, bodily pain, general health perception, mental health, role limitation due to emotional problems, social functioning, and vitality than those in preparation, contemplation, and precontemplation stage. In addition a significant interaction effect between stage of exercise and age was found on physical functioning, bodily pain, general health perception, mental health, and vitality. Conclusion: Perceived health-related QOL varies with stage of exercise. This finding suggests that health is related to both intention and behavior of exercise. Therefore it is important to consider cognitive-motivational and behavioral stage of change for developing exercise programs.
