A lot of educators claim that the open education should be performed in elementary classroom, but it is true that they do not suggest the specific direction of practicing open education in case of mathematics subject. Although a project lesson is recommended, there is little case that suggests the direction of practice and the evaluation method of project lesson. Therefore this study searchs for the possibility of practicing open education in elementary mathematics classroom by reviewing the portfolio assessment and suggesting the specific case of applying the portfolio assessment to project lesson. A portfolio is a folder in which is recording solution process, student's self reflection, and teacher's comment, about topics and problems more than one. Students can see their own varying aspects and recognize their own merits and demerits, sincerities, and potentialities by portfolio assessment. Futheremore, teacher can both grasp the student's cognitive situation and give them the professional advice about the cognitive development. That is, they can perform the instruction underlining the learner's ability and personality, by identifying what Vygotsky calls 'the proximal zone of development' through portfolio assessment. Consequently, portfolio assessment is an alternative evaluation method for integrating process and product of learning, and can be used as an important tool for developing the learner's potential possibility of self-realization.

한국의 뽕나무 해충은 210종 이상이 기록되었다. 과거 4반세기 동안 다수의 합성농약이 농림해충 및 위생해충 방제에 큰 공헌을 해 온 것은 주지의 사실이다. 그러나 뽕나무의 해충에 대해서는 농약에 대한 내약력이 가장 약한 누에에 미칠 악영향 때문에 여러 가지 어려운 점이 많아서 외국에서도 잔효성이 짧은 TEPP 또는 DDVP등이 사용되고 있을 정도이다. 한국에서도 뽕나무순혹파리 방제를 위해서 초여름에 BHC 분제의 토양처리가 실천되어 왔으며 근래에는 뽕나무애바구미의 피해가 심해져서 몇 가지 살충제로 방제시험이 백에 의해서 이루어 졌을 뿐이다· 따라서 뽕나무해풍 방제를 위해서는 천적을 이용한 방제가 바람직하다 하겠다. 필자들은 우선 천적으로서의 거미의 분포 실태를 파악하기 위하여 수원시 소재 잠업시험장 뽕밭에서 1971-72년에 조사하였다. (Fig. 1) 조사된 뽕밭의 면적을 27a이었으며 9개의 조사구를 택하고 이것을 생태적 환경에 따라 3군으로 나누어 비교해 보았다. A, B 및 C구는 동쪽 가에 위치하며 가로등과 3개의 잠실의 등불의 영향을 받아 해충의 밀도가 높았으며 E, D 및 H구는 뽕밭의 중앙부이며 뽕나무 오갈병의 피해가 심하여 뽕나무가 작았고 또한 결주도 많았다. F, G 및 I구는 도로를 격하고 뽕밭 또는 초지에 면한 가장자리 이었 다. 이밖에 수시로 근처의 딴 뽕밭에서 채집한 것도 포함하여 4,987마리의 거미를 조사한 바 17과 47속 66종에 이르렀다. 이것을 Abe의 보고와 비교한 때 종수가 월등 많았으며 또한 Kayashima의 보고와는 달리 풀거미속(Agelena)거미가 훨씬 적은 것이 특이하였다. 채집된 거미를 그 생태에 기초하여 4군으로 나누어 천적으로서의 가치를 비교해 보면 다음과 같다. A군 : 대형의 둥근 망을 치는 종류들로서 날으는 곤충을 잡아먹는데 천적으로서 그다지 중요하지는 않다. 106주에서 245마리가 채집되었으며 (Tetragnatha squamata)가 우량종이었다. B군 : 소형의 둥근 망을 가지나 잎사이에 치는 종들로서 비록 몸은 작지만 가장 중요한 천적이다. 꼬마거미과 애접시거미과에 속하는 거미들이며 18종, 2,815마리가 잡혔다 우점종은 (Erigoridium raminicola),(Theridion octomaculata) (Enoplognatha spp.)이었다. C군 : 떠돌이거미로서 소형곤충을 잡아먹어 유력한 천적이다 26종 1,727마리가 잡혔으며 게거미과, 깡총거미과 및 염낭거미과의 거미들이 우점종이었다. D군 : 지상을 걸어다니는 떠돌이거미로서 늑대거미과가 약간 잡혔으나 천적으로서 중요한 것으로는 생각되지 않는다. 앞으로 이들과 해충과의 관계를 조사구명 해야 할 것이다.

This is a case study on how infants' behaviors change after their child care teachers use Responsive Interactions to them. The participants are five infants and five child care teachers from five employer-supported child care centers run and managed by H foundation. This study analyzes the changes in infants' pivotal developmental behaviors based on interactions between an infant and a child care teacher in video recordings, anecdotal records, Reflective Journal written by the teachers, and data on in-depth interviews with the child care teachers. The results show that Responsive Interactions have brought positive changes to infants' pivotal developmental behaviors(Attention to Activity, Problem Solving Persistence, Involvement, Cooperation, Initiation, Joint Attention and Affect). It suggests that child care teachers who are in charge of taking care of infants should realize and practice the importance of Responsive Interaction Strategy in order to help the infants develop their pivotal behaviors.

As pioneers of the early video art, Steina Vasulka(1940-) and Woody Vasulka(1937-2019) had lead not only their own experimental arts, but also entire changes of contemporary avant-garde performance, music, and visual art. Two artists invented and developed electronic machines for video image-processing by collaborating with engineers, and performed creative experiment on transformation of digital image. For them, video art is not just a means of documentation. The Vasulkas' artistic practices were not bounded by conventional canons and rules in art world, and preferably were parts of active aesthetic strategies for coexistence of vision of human and vision of machine. Particularly, their video art recognized the video as the key medium in an era where media technology began to dominate the system of communication, and established artist's authority over manipulation of moving image electronically without depending on video camera. In that regard, we can value on their video art. Therefore, the paper reflects on the Vasulkas' art and life which have not yet been studied, and suggests academic interests in the context of their artistic activities and aesthetic strategies.

This study examined the characteristics of child maltreatment cases which occurred recently at the Day Care Centers in Korea. The study utilized the case records system of the National Child Protection Agency (K-CPS) and analyzed all the cases reported to the K-CPS from 2010 to 2012 (n=462). Using the case records abstraction system developed for this study, based on the Maltreatment Case Records Abstraction System (MCRAI; Trickett et al., 2009), the detailed information on abuse cases as well as disposition outcomes was abstracted. The results showed the relatively low rate of abuse designation, low rate of reports from the mandatory reporters as well as overwhelmingly high rate of physical abuse. Diversity was detected in severity ratings in each type of abuse. Finally, determinants of dispositions differed for children, perpetrators and daycare centers. Based on the results, implications for practice and child maltreatment research were discussed.
