본 연구는 긍정훈육 독서활동 프로그램이 보육교사들의 아동학대 예방에 대한 인식변화에 미치는 효과와 보육교사들의 요구를 알아봄으로써 보육교사에게 효과적인 아동학대 예방 프로그램을 제시하고자 한다. 본 연구는 전국 공공형 어린이집 보육교사 74명을 대상으로 아동학대 예방을 위한 "긍정 훈육 독서 활동 프로그램“을 6회 실시하였으며, 프로그램 사전과 사후에 보육교사들의 아동학대에 대한 인식 조사를 실시하였다. 주요 연구 결과는 다음과 같다. 첫째, 본 긍정 훈육 독서 활동 프로그램은 보육교사의 아동학대 예방 인식에 긍정적 영향을 미치는 것으로 나타났다. 둘째, 보육교사들은 아동학대 예방을 위한 다양한 복지 및 지원 방안을 요구하였다. 이러한 결과를 통해 아동학대 예방을 위한 다양한 교사들의 요구를 반영한 프로그램 지원 및 교사지원이 확대될 것으로 기대된다. The purpose of this study is to present effective child abuse prevention programs to child care teachers by identifying the effect of positive discipline reading programs on child abuse prevention and the needs of child care teachers. This study conducted a six-time "positive discipline reading activity program" to prevent child abuse among 74 daycare center teachers nationwide, and conducted a survey on the awareness of child abuse by childcare teachers before and after the program. Key findings include: First, this positive discipline reading activity program has a positive impact on child care teachers' perception of child abuse prevention. Second, child care teachers demanded various welfare and support measures to prevent child abuse. These results are expected to expand program support and teacher support that reflect the needs of various teachers to prevent child abuse.

Polar snow and ice are essential research materials to reconstruct past climate change as those preserve the Earth"s atmospheric composition. To measure trace elements in snow and ice samples from the polar regions, we have to keep the clean protocol and maintain the water quality for low blank levels below sub picogram per gram or femtogram per gram level. We periodically check whether the water quality is maintained as well as the maintenance of a clean laboratory. In this study, we have tested the pre-concentration methods: heating evaporation method, graphite heating method, and vacuum freeze-drying method to confirm the water quality. Heating evaporation method concentrated sub-boiling water in a Teflon beaker at 100℃ using an aluminum heating block. The graphite heating method concentrated sub-boiling water in a Teflon bottle at 80°C using a graphite heating block. In vacuum freeze-drying method, sub-boiling water in a LDPE bottle was frozen at -60°C, and then freeze-dried at a pressure of 0.350 mbar. We have measured trace elements in the concentrated water samples using an inductively coupled plasma-sector field mass spectrometry (ICP-SFMS). This fundamental research method will establish a reliable and stable methodology to control the water quality for the analysis of trace elements in polar snow and ice.
Drop on demand electro-hydrodynamic printing induced by square pulse voltage signal

Electro-hydrodynamic(EHD) printing is receiving a huge interest due to its high resolution printing capability along with many advantages such as reduced manufacturing steps and non-toxic, flexible processes. However, many issues are yet to be resolved to realize high volume fabrication process. In this work, to demonstrate high resolution EHD printing on demand, square pulse voltage signals are applied between a hole-type electrode and a nozzle where working fluid is supplied from a reservoir at constant pressure. By varying voltage signals and hydrostatic pressure applied to the nozzle, a change in jetting start time is observed. Also, continuous, fine jet pulsating, and droplet pulsating mode are observed as the voltage signal induced varies. Of all modes, the behavior of droplet pulsating mode with various voltage signals is studied and optimized voltage signal is demonstrated.

This article explores the two competing democratic concepts of liberalism and political equality in Korean politics. In the development of Korean democracy, liberalism has evolved as a form of anticommunism as a way to pursue social stability; meanwhile, political equality has emerged by means of civic participation as a way to seek equal opportunities to be involved in decision making. This article traces how political equality has tended to expand from the time of Kim Young-sam to the Roh Moo-hyun administrations, while liberalism dominated during the administrations of Lee Myungbak and Park Geun-hye. In addition, this article identifies different trends of civic participation between the progressive governments that promoted civilian ascendancy and the conservative governments that showed uncommunicative leadership in the decision-making process.
