Black staining of the teeth in children and adolescents does not cause pain or serious illness, but it can be socially debilitating for esthetic reasons. Black staining is easily removed through periodic professional mechanical tooth cleaning and ultrasonic scaling, but it can easily recur within few months. Using essential oil-containing mouth rinses diluted at 50% twice per day could prevent the black staining from returning after it is removed, reducing the need for mechanical treatments and improving esthetics.

최근 한국사회에서는 출산율의 저하로 인한 사회경제적 영향을 우려하여 대책방안을 강구하여야 한다는 논의가 증대되고 있다. 그런데 국가정책을 개발${\cdot}$추진하기 이전에 반드시 요구되는 것은 저출산 현상의 올바른 인식과 철저한 원인규명이다. 따라서 본 연구에서는 출산율 변화의 원인을 다각적으로 살펴보고, 향후 변화방향을 전망해 보고자 한다. 먼저 자녀출산의 변화를 결혼상태 변화와 유배우부인의 출산율 변화 부분으로 나누어 살펴본 결과, 과거와는 달리 최근의 출산율 저하는 유배우 부인에 의해서가 아니라 미혼자의 결혼연장 또는 독신생활에서 기인되는 것으로 나타났다. 이들 두 요인에 영향을 주는 변수로는 경기침체 및 직장불안정, 결혼가치관의 변화와 초혼연령의 상승, 자녀양육 관심증대, 자녀양육비 부담, 가정과 직장의 양립을 위한 사회적 인프라 부족, 여성의 자아욕구 및 사회참여 증대, 자녀효용가치 감소, 이혼 등 가족해체의 증대, 그리고 불임부부의 증대 등인 것으로 판단된다. 향후 출산율 변화를 전망해 보면, 저출산을 일찍 경험한 서구 선진국의 경우와는 달리 정책의 추진에 한계가 있어 선진국보다 더 낮은 출산율을 회복하는 데는 많은 어려움이 있을 것이라는 판단이다. 더군다나 젊은 미혼남녀의 가치관이 개인주의화 되는 경향이 있다는 점을 감안한다면 출산율 회복정책을 추진한다 하더라도 한계가 있을 수밖에 없을 것이다. 수년간 실시된 각종 실태조사를 분석한 결과에 의하면 현재의 경기침체가 회복될 경우 약 20%의 출산율 상승 가능성이 있으며, 이 때의 합계출산율은 약 1.43명 수준이 될 수 있을 것으로 예견된다. 또한 종합적 체계적 출산회복정책을 효과적${\cdot}$효율적으로 추진한다면 약 10년 후에는 합계출산율이 약 1.6 수준으로 회복될 것이라는 낙관적 견해를 가져본다. 그렇지만 정책의 강도에 따라서 회복수준은 현저하게 상이할 것이다.를 진단, 치료함에 있어 진행성 신질환의 가능성을 시사하는 예후인자가 없다면 신생검보다는 지속적이고 정기적인 추적관찰만으로도 충분할 것으로 생각된다도 등은 양군 사이에 유의한 차이가 관찰되지 않았다. 발견 당시 혈청 $C_3$치의 감소는 모두 11명(61.1%)에서 관찰되었는데, 증상군에서는 7명(87.5%), 집단뇨검사군에서는 4명(40%)으로 증상군에서 혈청 $C_3$치의 감소가 보다 현저하였다. 그러나 추적관찰 기간 동안 증상군에서는 7명 중 4명, 집단뇨검사군에서는 4명 중 1명에서 혈청 $C_3$치는 정상범위로 증가하여 최종 관찰시점에서는 6명 (33.3%)에서만 혈청 $C_3$치의 감소가 지속되고 있다. 혈청 $C_3$치의 감소를 보인 경우를 다시 병리조직학적 분류에 의해 세분하여보면 발병당시에는 I형 8명(61.5%), II형에 1명(100%), III형 2명(50%)에서 관찰되었는데, 최종 시점에서는 I형 4명(30.8%), II형 1명(100%), III형 1명(33.3%)이었다. 또한 증상군에서 세포성 반월체형성과 세뇨관위축의 빈도가 높았으며, 사구체 혈관벽 비후와 사구체 간질의 증가의 정도가 집단뇨검사군에 비해 통계적으로 유의하게 높았다. 결론: 무증상성 요이상을 가진 환자에서 신장조직검사 실시 후 MPGN으로 진단되는 증례가 증가하고 있고, 오히려 증상을 동반하는 경우보다 빈도가 증가한다는 사실은 집단뇨 검사에서 소변의 이상소견이 발견되어 신장 조직검사를 실시할 경우 혈청 $C_3$치의 감소 여부에 관계없이 MPGN도 진단적 고려 대상이 되어야 한다고 생각한다.신장 조직검사를 시행한 결과 진행성 경과를 취할 수 있는 막 증식성 사구체 신염과 매우 희귀한 증례인 신유전분증 등으로 진단됨으로써 지속성 단백뇨의 경우 정확 진단적 접근이 필수적임을 알 수

본 연구를 통하여 대형할인점 이용자, 재래시장 이용자, 그리고 수퍼마켓 이용자들의 각 쇼핑장소를 중심으로 한 거주지역 공간적 분포 및 쇼핑패턴의 차이를 비교한 결과. 이 세종류의 쇼핑장소 이용자들간의 각 쇼핑장소들 중심으로 한 거주지역 분포의 공간적 패턴 및 쇼핑통행 패턴은 상당한 차이를 나타내고 있다. 또한 대형할인점을 이용자를 제외한 재래시장 이용자와 슈퍼마켓 이용자들을 대상으로 그들이 이용하기를 원하는 대형할인점의 이용을 제한하는 주요 요인을 분석한 결과 통행거리, 운전면허 미소지, 자가용 승용차 미보유 등 대형할인점으로의 접근을 위한 과정에서 발생하는 제약 요인들이 가장 큰 비중을 차지하고 있는 것으로 나타난다. 이러한 점들을 볼 때, 재래시장 및 수퍼마켓이 주민들의 일상적인 쇼핑장소의 역할을 할 때와는 달리 대형할인점의 등장은 이곳으로의 주민들의 접근능력의 차이에 따라 주민들간 일상적 소비장소의 차별화가 진행될 수 있음을 시사한다. 특히 최근 대형할인점의 입지가 가속화되고 이에 따라 재래시장 및 수퍼마켓의 기능이 쇠퇴하고 있음을 고려할 때, 신체적 그리고 사회경제적 특성의 차이에 따라 대형할인점으로의 접근에 제한을 받는 주민들의 일상적 소비공간은 더욱 위축되고 고립될 가능성이 있다.

This thesis reviews the process in which the regulation systems against ownership concentration of newspapers established with the opportunity of legislation of the periodical act in 1987 was reinforced as they were all amended to the newspaper act in 2005 and as they were again amended in 2009 it came to confront crisis in the aspect of press law legislation history. The regulation systems against ownership concentration of newspapers established based on the principle of legality of newspaper function in the Clause 3, the Article 21 of Constitution was reinforced as the newspaper act in 2005 and in 2006 they began to shrink following the Constitution Court decision against newspaper act. As newspaper act and broadcast act are revised in 2009, regulation against combining the management of newspapers with broadcast and regulation against owning multiple number of newspapers came not to exist. Because in this process, the opposition party also allowed limited cross-ownership of newspaper and broadcast, it can be said that the system of newspaper ownership regulation confronted the crisis of dissolution. The instruction of regulation alleviation in a short period of time in spite of the fact that regulation alleviation which allows cross-ownership of newspaper and broadcast is the matter of policy that should be decided after long-term review of the change of media environment and the progress of the power of domination of public opinion is dangerous. Newspapers are strong media with terrestrial broadcast in formation of public opinion on politics. It's because it is difficult to ignore the worry that the power of domination of public opinion of the newspapers which are in oligopoly of newspaper public opinion market can be spreaded to the territory of report broadcast. From the point of view that there is probability for democracy to be ultimately threatened due to the shrink of political Darwinism caused by concentration of media ownership, the alleviation of ownership concentration of newspapers should have premise of long-term social discussion.

This study examines the problems of children exposed to family violence. As a result, the children exposed to family violence exhibit various emotional, behavioral and social problems and distorted perceptions and inappropriate reactions toward family violence. Based on these results and existing programs for children exposed family violence, an integrative group program has been devised. The program was applied to two groups of the children and an experimental study was conducted to examine its effectiveness on emotional problems, aggressiveness, social skills and perceptions/reactions toward family violence. As a result, the experimental groups have shown an overall significant improvement in scores on emotional problems, aggressiveness, social skills and perceptions/reactions toward family violence. The study offers the following recommendations for clinical social work practice. First, great efforts to alleviating the problems of children exposed to family violence should be made continually. Second, special attention should be paid to reflect the characteristics of our own culture in clinical social work intervention and to do so, various practical intervention skills suitable to our culture should be developed. Finally, many different intervention models for children exposed family violence should be developed and researches comparing those models should be carried out.

Start-up support policy is expanding for the activation of creative economy. Domestic start-up is activated in early 2000, but is shrinked rapidly because there is not enough collaborative system of R&D, start-up, finance, and management support. Many organizations and collaborative environment in Silicon valley of USA is developed for long time. In Korea, creative economy is constructing rapidly led by government like building industrialization and information society. VCDP(Virtual Cluster-type Dynamic Collaboration Platform) is a good tool for the start-up support policy. This study explains the necessity and effectiveness of VCDP and suggests creative activation policy using this tool.

This study attempts to elucidate manifold dimensions of gendered accessibility experiences. How gender roles(household responsibilities) differentiate accessibility experiences between women and men is explored through the comparison of married dual-earner couples' parental status, using the US Portland activity-travel diary dataset with GIS-based geocomputation results of(time-geography based) space-time accessibility. First, this study shows how gender division of labor within the household still permeates current society, despite the widespread belief of the social change toward a gender-egalitarian society. Then, the study pays special attention to the way gender roles structure individual accessibility experiences of women and men differently, and, in turn, the way such accessibility experiences take a form of gendered spatiality. Gendered spatiality is examined through the analysis of accessibility space as well as activity space in order to ascertain women's home-attached and spatially entrapped characteristics. More household responsibilities throughout a day and, even more, the time constraint of picking up children at the daycare centers after work lead women's possible activity space to be more home-centered. The analysis of the spatio-temporal context of accessibility space makes gendered spatiality visible. However, the findings suggest that behavioral outcomes should be understood with an explicit awareness of constraints individuals face. It is because the revealed activity spaces can be not only an outcome of constraint but also an outcome of choice. Behavioral outcomes should not be treated as a straightforward expression of the level of constraints. It is problematic to expect that behavioral outcomes directly mirror the level of constraints. It is also problematic to suppose that the level of constraints can be straightforwardly elicited from revealed behavioral outcomes.

The purpose of this study is to generate a substantive theory that accounts for the social readaptation of the women who have engaged in prostitution and propose a practical program for them. We used the grounded theory developed by Strauss and Corbin(1990). Raw data were collected through the in-depth interview, documents and observation. We used constant comparative method for the data analysis. The nine women who had the exprience of prostitution have participated in this study. As a result of the data analysis, in open coding were generated 116 concepts, 29 subcategories and 12 categories, In axial coding the outcomes of a paradigm model were as follows. The causal conditions were named 'hostile environment' and 'the self endowed stigma'. The phenomenon turned out to be 'living as an anonymous being'. The contextual conditions were named 'cohesion of family', 'being pushed' and 'shrinked emotion'. The intervening conditions were presented to be 'desire of self restoration as a social being', 'reactionary reconstruction'. The action/interaction strategies turned out to be 'shifting of social status', 'neighbor alliance'. The consequences were presented to be 'psychological wayfarer' and 'tentacular living'. In selective coding we found a core category, 'repetition of leaving and returning from the life world'. Based on the phenomenon, two types of participants life attitudes were found as follows : present hesitating type, self concealing type. Following the adove results, We finally suggested the need to develope a community oriented case management model.

Purpose: This study was conducted to explore the relationship between aggression, self-esteem, and social withdrawal. Methods: This research is a cross-sectional survey. This study used the 5th-year data of the Korean Children & Youth Panel Survey (KCYPS) including 218 middle school students having delinquent behavior. The collected data was analyzed through $x^2$ test, t-test, ANOVA, Pearson's correlation, and hierarchical multiple regression, using SPSS/Win (ver. 23.0). Results: Significant positive correlations were found between aggression and social withdrawal and between aggression and self-esteem. Higher aggression was associated with higher social withdrawal and lower self-esteem. The results of the 2-step regression are as follows. Aggression was negatively correlated with self-esteem, whereas self-esteem was positively correlated with social withdrawals. The hierarchical multiple regression showed that 21% of the variance of aggression was significantly accounted for by self-esteem and social withdrawal. The most significant factor influencing aggression was social withdrawal. Conclusion: These results suggest that earlier screening and intervention programs to increase self-esteem and decrease social withdrawal for early adolescents should be developed to prevent aggression.
