Objectives : The aim of this study was assessment of the variation of urinary mercury concentrations after removal of amalgam fillings in children. Methods : 10 elemental school children with amalgam filling tooth surfaces were took part in this study. One dentist recorded the number of amalgam filling surface, and general characteristics of subjects were surveyed by questionnaire. Each urine samples were collected before, immediately after and after 24 hours amalgam removal. The statistical analysis was performed using the SPSS 18.0. Results : The mean concentration urinary mercury immediately after amalgam removal was higher (5.70±1.20 ㎍/g creatinine) than before amalgam removal (5.28±1.53 ㎍/g creatinine). The mean concentration urinary mercury level whose have 1-10 amalgam removal surfaces was increased after amalgam removal compared with before. Conclusions : Mercury concentration in urine was influenced by amalgam removal.

본 연구는 우리나라 어머니의 산후 우울 성향이 높은 집단과 일반 집단 간 어머니와 영아의 상호 작용 시 신체접촉특성에 대해 알아보고자 하였다. 이를 위해 두 집단 간 신체접촉특성의 차이를 분석하고, 신체접촉특성 중 두 집단 간에 영향을 미치는 유의미한 요인을 탐색하였다. 또한 우리 나라 어머니들의 신체접촉유형을 알아보고 결과로 나타난 신체접촉유형이 어머니들의 정신건강과 관련이 있는 지를 알아보고자 하였다. 연구대상은 서울에 위치한 종합병원 3곳의 산부인과에서 생후 6-8개월 된 영아의 발달평가를 진행한 후, 어머니의 산후우울(EPDS), 양육스트레스(K-PSI), 우울(CES-D), 삶의 만족도(SWLS), 결혼 만족도(K-MSI)를 사용하여 어머니의 산후우울의 점수가 높은 집단 중 무작위로 30쌍, 각 척도에서 유의미한 어려움이 측정되지 않은 집단 중 무작위로 60쌍을 선정, 대상으로 하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 산후우울성향이 높은 산후우울성향군과 일반군 간 모든 측정도구에서 유의미한 차이가 나타났다. 둘째, 산후우울성향이 높은 집단과 일반 집단 간 측정도구 별로 다른 요인보다 유의미한 영향을 미치는 요인을 탐색하는 것이 가능하였다. 셋째, 어머니의 신체접촉특성은 유형화가 가능하였으며, 이는 산후우울 정도와 높은 관련성을 보였다. 즉, 본 연구에서 대상이 된 우리나라 6-8개월 영아를 둔 어머니들이 영아와의 상호작용 시 나타내는 신체접촉특성은 4개의 유형을 나타내며 이는 산후우울 정도와 유의미하게 연관이 되어있다. 특히 산후우울 정도는 어머니가 영아에게 행하는 신체접촉기능, 신체접촉특성과도 유의미하게 관련이 되어있음이 나타났다. This study aims to examine tactile communication styles of Korean mothers and identify effects of tactile communication on mother-infant interactions depending on the degree of postnatal depression of mothers. Subjects were selected from mother-child pairs who visited obstetrics and gynecology departments of three general hospitals in Seoul six to eight months after child birth. The children were checked for developmental state and mothers were examined in terms of postnatal depression by the EPDS, parenting stress by the K-PSI, depression by the CES-D, satisfaction with life by the SWLS, and satisfaction with marital life by the K-MSI. Among the mothers and their children, 30 mother-infant pairs were randomly selected from mothers with a higher degree of postnatal depression, and other 60 mother-infant pairs were randomly selected from mothers who had no significant problems. The findings are: (1) significant differences were found in all measures between the group of mothers with a higher level of postnatal depression and the normal group; (2) significant variables were found for each measure between the two groups; (3) it was possible to classify the mothers based on the characteristics of their tactile communication, which had a high correlation with the degree of postnatal depression. Interactions between six- to eight-month-old infants and their mothers showed four styles of physical touch, which had a significant relationship with the degree of postnatal depression of the mothers. In particular, the degree of postnatal depression had a significant relationship with the function and characteristics of mothers' touch on their children.

Objectives : The purpose of this study is to investigate the correlation between amalgam restorations and urinary mercury levels in children for 1 year. Amalgam restoration has been widely used for over 200 years. But released mercury from amalgam can increase the concentration of mercury in the body. Methods : The subjects were 463 elementary school children. Oral examination, urine sampling, and questionnaire survey were performed at baseline and after 1 year. Results : Amalgam restoration increased the urinary mercury level to 0.55±0.13 ㎍/g creatinine. In the regression analysis, variation of urinary mercury excretion were positively associated with amalgam surfaces and fish consumption. Conclusions : Small amount of mercury release from amalgam restoration was closely associated with increasing urinary mercury level.

Objectives. The aim of this study was to evaluate the association between metabolic syndrome and periodontitis in Korean adult population. Methods. We analyzed a total of 2,808 subjects aged 18 years or older who participated in a Korea National Health and Nutrition Examination Survey in 2007. Periodontal health was measured using Community Periodontal Index (CPI). Periodontitis was defined as CPI score was three or four. Metabolic syndrome (MS) was the diagnosis when participants were positive for three or more of five components of MS. The association between periodontitis and MS was analyzed using a χ2-test and logistic regression analysis (using SPSS 17.0). Results. The prevalence of periodontitis was higher among people who were male, older, and current or ex-smokers. People having periodontitis were likely to have lower household incomes, and do more frequent toothbrushing and drinking. Persons having MS had significantly higher odds of having periodontitis than normal people; the odds ratio was 1.23 after adjusting for age, gender, education, intake of alcohol, smoking, toothbrushing, oral hygiene goods, eating between meals, exercise and household income (95% CI: 1.02~1.47). Conclusions. Korean adults with MS had a higher risk of periodontitis. Further studies are required to investigate a casual relationship between MS and periodontitis.

본 연구는 시판중인 어린이 음료가 치아 표면의 탈회에 미치는 영향에 대해 평가하고자 하였다. 치아우식이 없는 건전한 표면의 우치로 만든 시편 15개를 4개의 실험군(n=12)과 대조군(n=3)으로 각각 나누었다. 모든 샘플은 각 각의 음료에 담근 후 48시간 동안 37℃의 배양기에서 처리 한 후 표면의 변화를 관찰하였다. 음료처리 후 법랑질 표 면의 탈회로 인해 표면미세경도 값은 감소하였고, DIGNOdent 값은 증가하였다. 이러한 현상은 특히 탄산음료에서 통 계적으로 유의한 차이를 보였다. 한편, 음료 처리 후 주사전자현미경 상의 법랑질 표면은 어린이음료에서 가장 많은 탈회 현상이 관찰되었다. The purpose of this study was to observe the demineralization effects of children's range beverage on bovine enamel. 15 bovine teeth without dental caries were divided into 4 experimental groups (n=12) and control group (n=3). All samples immersed in beverages maintained 48 hours by 37℃ in incubate respectively. The surface microhardness values(⊿VHN) between before and after 48 hours treatment decreased and DIGNOdent value increased because enamel surface were corroded by experimentation beverage. Especially, there was statistical significantly difference in the carbonated drink. Morphological changes by scanning electron microscope were indicated that children's range beverage cause significant enamel demineralization effects on bovine tooth surface among five beverages.

Objectives. The purpose of this study was to analyze the relationship between the risk of newly developed dental caries and diet pattern among early adolescence for three years as a longitudinal design. Methods. A middle school in a city of Korea was conveniently selected for this study. An oral exam and a food frequency questionnaire (FFQ) were performed every year from 2007 (baseline) to 2010 (end point) among 244 middle school students who consented to this survey. All the collected data were analyzed using SPSS 17.0. Corresponding p-values were considered significant at values of less than 0.05. Results. With a greater protein and lipid consumption, a lower mean change of DMFT index was observed, but there were no statistically significant after adjusting the DMFT index at baseline. Among the essential minerals, the group that consumed less calcium, phosphorous, magnesium and fluoride were likely to have a higher increment of the DMFT index. In terms of microelements, for the early adolescents who consumed more copper and selenium, less change was revealed in the DMFT index over the three years, but there were no differences. Conclusions. This study may suggest that a greater carbohydrate intake tends to result in a higher DMFT increment. Further studies need to be implemented to investigate the causal relationship between minerals and microelements and dental care.

생존하지만 성공하지 못한 자아상-John Fowles의 “The Ebony Tower”

백혜진(Hyejin Baek) 인문사회과학기술융합학회 2018 예술인문사회융합멀티미디어논문지 Vol.8 No.5

이 논문의 목적은 “The Ebony Tower”에 나타난 작가 John Fowles의 저술의도를 규명하는 것으로서 주인공이 현대예술의 한 단면인 추상성의 일반적 규범에 굴복하여 자기인식의 기회를 선택하지 못한 점을 지적한다. 이 중편소설은 포스트모더니즘의 한 성격으로 절대적 가치가 부재하다는 사실을 한 늙은 화가의 여성편력 그리고 불륜과 낭만의 갈등을 중심으로 서술하고 있다. 사실 이 이야기는 이틀 동안에 네 명의 서로 다른 성격을 가진 등장인물들이 식사하는 장면과 젊은이들이 나체로 수영을 하는 야유회 그리고 짧은 성적 에피소드 이외에 별다른 사건을 다루지 않는다. 하지만 그것은 현대 예술의 추상성과 재현예술의 속성을 성욕의 힘과 정당성에 비추어 대조하고 있다. 이 과정에서 책의 제목인 The Ebony Tower는 현대예술의 애매모호함과 획일성을 비난하는 것을 의미하고, 등장배경인 Coetminais는 도시의 무미건조한 세계와 다르게 자신의 진정한 자아를 드려다 볼 수 있는 거울의 역할을 함이 드러난다. This paper aims to reveal the writer John Fowles’s intention shown in “The Ebony Tower” and points that the protagonist finally cannot choose the opportunity to achieve his self-awareness owing to surrendering to the general norm of abstraction that is one aspect of the modern art. This novella describes the absence of absolute value as one of the characteristics of post-modernism based on an old artist’s womanizing and the conflict between infidelity and romance. Indeed, this story does not treat other affairs except for the scene where four characters have a meal, the picnic the young people swim in the nude, and a single sexual episode. However, it compares the abstraction of modern art with the attribute of the representational art in the light of the power and justification of sexual desire. In this process, it is found out that the topic of The Ebony Tower means criticizing the ambiguity and uniformity of the modern art, and the space background Coetminais plays a role of a mirror with which to look into one’s authentic self unlike the flat world of the city.

Objectives: Dental amalgam is a widely used filling material for oral cavity. The released mercury vapor from amalgam could have systemic adverse effects potentially. The purpose of this study is to evaluate the relationship between dental amalgam and urinary mercury levels in children during a 6-month timespan. Methods: A total of 525 elementary school children participated in this study. Oral examination was carried out from one dentist. Urine samples collected at baseline and at 6 month were analyzed for mercury and creatinine excretion. Additionally, general characteristics of subjects were surveyed by a questionnaire. The statistical analysis was performed using the SPSS 18.0. Results: Greater amalgam surfaces were associated to higher urinary mercury levels; this tendency was similar at the 6-month observation after the correct baseline data. In the multivariable model, urinary mercury excretion was only associated with amalgam surfaces positively. Conclusions: Even a small amount of mercury uptake from dental amalgam has been associated to increase the mercury concentration of urine.

언어와 소통에 대한 메타픽션: 존 파울즈의 불쌍한 코코 , 수수께끼 , 구름

백혜진(Baek, Hyejin) 조선대학교 국제문화연구원 2017 국제문화연구 Vol.10 No.2

John Fowles, famous for writing The Collector, The Magus, and The French Lieutenant’s Woman, certainly deserves to be called a pioneer of postmodernism novels, attacking the inauthentic lifestyle blinded by the reason in seemingly unusual ways of an author’s narration, clever implication and description. Besides, his collection of stories, The Ebony Tower—one novella “The Ebony Tower,” one translation “Eliduc,” and three short stories, “Poor Koko,” “The Enigma,” and “The Cloud”—integrates the works in thematic and formal ways. However, the precedent studies have not covered the last three stories much except for the first two works. It is important to analyze The Ebony Tower collectively because the book means a watershed leading to the writer’s later works such as Daniel Martin and Mantissa. This paper aims to find out the common theme of the stories and observe the writer’s literary world. This analysis reveals that the three works are closely related to the relationship between language and communication. “Poor Koko” emphasizes the tradition of language for connecting statuses and generations; “The Enigma” points at the collapse of rationalism represented by language resulting in the absence of communication; and “The Cloud” is concerned about the fragmented aspect of language producing the disconnection of communication. I wish this study contributes to expanding research area of postmodernism novels through Fowles’s works.
