The purpose of this paper is to address He possibility of the teaching of 'proof' in elementary mathematics, on the assumption that proof in school mathematics should be used in the broader, psychological sense of justification rather than in the narrow sense of deductive, formal proof. 'Proof' has not been taught in elementary mathematics, traditionally. Most students have had little exposure to the ideas of proof before the geometry. However, 'Proof' cannot simply be taught in a single unit. Rather, proof must be a consistent part of students' mathematical experience in all grades. Or educators and mathematicians need to rethink the nature of mathematical proof and give appropriate consideration to the different types of proof related to the cognitive development of a notion of proof.

Since the working machine generates an excessive loud noise as much as its use-purpose and dimension, those damages are occurring to the exposed workers such as unpleasant sense, stress and occupational hearing-impaired. Accordingly, as one of the measures for prevention such loud noise, various soundproof protection tools were developed. However, such soundproof protection tools were presented the physical measured value only, it is real state that the psychological study result with regard to the soundproof effect which the workers are actually feeling, is not existing. On such point of view, with the object on the typical earplugs and earcaps among the soundproof protection tools, this study has ever tried a subjective evaluation about the degree of soundproof effect through Psycho-acoustics experiment. It is considering that such study result could be utilized as the useful material when establishing the soundproof measure for the workers in the future.

The article proposes that empathy differs in severity and types among students of different specialties. And to test this hypothesis, an experimental study of students from 4 different faculties was carried out. As a result of the study, it was found that empathy is more pronounced among students of "humanitarian" specialties, and students of "exact" specialties have the least pronounced empathic abilities.

제품에 대한 장점만 전달하는 일면 메시지는 소비자 구매행동에 영향을 주기 위해 과장하여 만들어 낸 것으로 부정적인 인지 반응이 형성될 수 있는 한편, 제품의 장단점을 함께 언급하는 양면 메시지는 광고메시지나 광고주에 대한 신뢰도에 긍정적인 영향을 미칠 가능성이 크다. 본 연구는 광고 메시지의 유형에 따른 광고태도와 수용의도의 차이를 밝히고, 나아가 소비자의 자아해석과 제품유형의 조절효과를 분석하는 데 그 목적이 있다. 실증분석 결과, 양면 메시지의 광고효과가 일면 메시지에 비해 상대적으로 높은 것으로 조사되었다. 나아가, 메시지 유형이 광고태도와 메시지 수용의도에 미치는 영향에서 소비자 자아해석의 조절효과는 유의한 것으로 나타났다. 하지만 제품유형의 조절효과는 메시지 수용의도에 대해서만 유의한 것으로 조사되었다. 본 연구의 결론에는 연구결과의 요약과 시사점, 그리고 한계점을 제시하였다.

Objectives: Stress may have an impact on treatment types that patients receive for temporomandibular disorders (TMDs). This study sought to investigate the relationship between the stress index and type of treatments in patients with TMD. Materials and Methods: The psychosocial well-being index-short form (PWI-SF) was used to evaluate stress levels in ninety-two patients with TMD. Treatment types were classified into two groups: one group received counseling, physical therapy or medication, while the second group received splint therapy or surgical intervention. Results: The high-risk group (PWI-SF${\geq}27$, the higher the points, the more severe the stress level) was more frequently treated by splint therapy than the low-risk group (PWI-SF<27). Female TMD patients reported higher PWI-SF scores than male TMD patients. Conclusion: This study suggests a relationship between stress levels and treatment types for patients with TMD. Thus, the appropriate evaluation and management of stress could be an important factor in treating TMD.

As a type of forehead make-up, aekhwang is found in Janghwon's and of the late T'ang period. Hwajeon is seen in lots of figure paintings made between the Prosperous the late T'ang periods. Most eyelid make-ups shown in the figure paintings are round-shaped wolmi and yuhyeopmi in type. Besides, other creative types like gyeyeopmi, paljami and iljami are found. Lips are found made up clearer and more red as the times went from the early and the late T'ang periods.

As elder abuse has become a social problem, it has drawn a great deal of attention from researchers and policy-planers. While there have been a number of studies addressing various issues related to elder abuse, the present study aims to explain whether and how the perception of elder abuse would differ among the elderly themselves. In particular, the study focuses on the differences between urban and rural areas. Family-centered culture is believed to have a stronger influence in rural areas compared to urban areas. This cultural tradition highlights the importancy of the family compared to the individuals. Thus, the elderly who experience abuse would take it as personal matter rather than publicizing it. In addition, the information and campaigns on preventing elder abuse are less prevalent in rural areas than in urban areas due to limited communication networks. For these reasons, the study suggests a hypothesis that the elderly in rural areas are less perceptive to elder abuse. Using 6,709 persons aged 65 and over from a nationwide survey conducted by the Korean Institute for Health and Social Affairs in 2009, the study ran regression analysis on 4 types of elder abuse including psychological, financial, physical and neglect. The results show that regardless of types of abuse, the elderly in rural areas have lower levels of perception than the elderly in urban areas do. In addition, the frequency of social activities is positively related to the perception of elderly abuse. This is also true for the different types of elder abuse. The findings suggest that social effort to prevent elder abuse consider the urban-rural differences and their sources.

본 연구는 충 남북 지역에 거주하는 노인 252명을 조사대상자로 하여 정보 활용과 삶의 질과의 관계를 분석하였다. 이 과정에서 독거노인과 일반노인 집단으로 나누어 비교분석하였다. 본 연구에서는 자료분석을 위하여 PASW Statistics 18.0을 이용하였다. 주요 연구결과는 다음과 같다. 첫째, 조사대상자들의 정보 활용은 일반노인 집단이 유의미하게 더 높은 것으로 나타났다. 삶의 질 하위영역에서 '정신 심리적 건강' 및 '사회적 관계' 영역은 일반노인 집단이 유의미하게 더 높은 것으로 나타났으며, '환경' 영역은 집단별로 차이가 나타나지 않았다. 둘째, 삶의 질에 미치는 영향 요인은 하위영역별로 두 집단이 동일한 것으로 나타났으나, 그 요인의 영향력은 집단별로 다른 것으로 나타났다. 두 집단에서 경제적 상태가 가장 크게 영향을 미치는 것으로 나타났고, 정보 활용, 교육수준, 거주 지역 등은 집단에 따라 영향력이 다른 것으로 나타났다. 특히, 두 집단 모두 '정신 심리적 건강' 영역에서 정보 활용의 영향력이 가장 작은 것으로 나타났다. 이와 같이 본 연구는 노인들의 가구 특성을 고려한 실증적 분석을 진행함으로써 고령화 및 정보화 사회에 맞추어 노인들의 정보 접근을 강화하고 삶의 질 향상을 위한 구체적인 실천전략을 제시하였다는데 연구의 의의가 있다.
