코로나-19 상황이 지속 되면서 유아들은 유아 교육 기관에 가지 못하고 집에서 부모와 보내는 시간이 늘어나고 있다. 부모들은 자녀들에게 한글 단어 학습이나 놀이 활동을 가르치기 위해 집에서 많은 시간을 보내야 하는 상황에 직면해 있다. 이는 부모에게 많은 심리적 부담과 스트레스로 작용이 되고 있다. 본 연구에서는 부모의 심리적 부담을 덜어 주기 위해 블록 코딩기법의 인공지능 블록을 이용하여 한글 단어 교육과 놀이 활동을 지원할 수 있는 학습 보조 시스템의 설계 및 구현을 제안하였다. 제안된 시스템의 활용은 자녀의 학습 지도에 대한 부모의 부담을 경감시킬 수 있을 뿐만 아니라 실제 유아 교육 현장에서도 적극 활용이 될 수 있어 많은 학습효과를 기대할 수 있다.

암성 통증의 80%는 진통제를 투여하는 약물치료로서 조절될수 있지만 $10{\sim}20%$는 다른 대책이 필요하다. 신경파괴제를 사용하는 블록은 이런 경우 중요한 역할을 한다. 신경블록은 암환자의 통증을 예방하고 삶의 질을 증가시킬수 있다. 특히 암성 통증이 신체 말단부위나 어떤 한 부위에 국한되 있는 경우 말초신경블록이나 교감신경블록은 좋은 효과를 나타낸다. 신경파괴제를 사용하는 교감신경블록 특히 복강신경총블록은 조기에 시행하면 훨씬 효과적이며 장기간 효과를 나타낸다. 환자 선택이 성공적인 결과를 얻는데 중요하다. 신경파괴제를 사용하는 신경블록은 복부 및 골반강내 암성통증을 감소시키고 진통제의 사용량을 감소시킬뿐 아니라 진통제에 관련된 부작용을 감소시키므로서 삶의 질을 향상시킨다. 따라서 조기단계에서 보다 적극적인 신경블록요법이 권고된다.

This study explores the types of daily routines in child care centers based on the time planned for indoor free choice activities, outdoor activities, group activities and nap/rest. The daily routine plans of 63 classes of 0 to 2-year-olds and 51 classes of 3 to 5-year-olds were cluster analyzed. Also, openness and closeness of child care programs as well as the most participated indoor/outdoor activities were examined using questionnaires developed for teachers. The results were as follows: First, teachers planned the most time for free play choice activity and comparatively less time for outdoor play during the day. Time for rest and naps were planned more for 0-2 year-olds whereas group activities were planned more for the 3-5 year-olds. Second, 3 daily routine types were found in the daily plans of child care centers, such as "Low-Activity Oriented," "Free Choice Activity Oriented" and "Group Activity Oriented" in 0 to 2-year-old classes and 3 to 5-year-old classes. Also, "Group Activity Oriented" type in 0 to 2-year-old classes showed more "closed" child care programs than the "Free Choice Activity Oriented" type. However, no difference was shown among the 3 types of daily routines in the openness and closeness of 3 to 5-year-old child care programs. Finally, all children, regardless of the types of daily routine, participated most in block activity and role play indoors and fixed-play equipment, sand play and free play outdoors.

The construction of settlement house in a permanent rental housing development area started between 1989 and 1992, planning of supplying two hundred fifty thousand residences, settlement house became compulsory as a welfare facilities. As a part of Welfare program for low income families, number of settlement housing increased dramatically, also domiciliary welfare center was beginning to set up as a branch of settlement housing to strengthen its service towards families and local communities, thus numerous social welfare organizations play a crucial part in resolving a welfare problem for low income families while satisfying local community's needs. However, despite of these efforts, the number if institutions cannot handle demand of local community's needs and number of welfare institution programs. as a solution, the alternation of space is being used, however, it did not solve basic problem, even worsen in terms of space efficiency.

This paper deals with the analysis of rock slope stability using the distinct element method. This method consists in analysis of the interaction of discrete block assemblage delimited by elementary joints, which permits to consider the heterogeneous, anisotropic and discontinuous features of the rock mass. In particular, we were able to show that this method, and especially the BRIG3D software, is an outstanding tool which gives informations of greatest interest in order to analyze the toppling mechanisms. We have confirmed the fundamental role of the rock mass structure with different simulations. In the case of toppling phenomena, the essential parameter is the dip of major discontinuities. It has an influence on the intensity and volume of deformations. The anisotropic and heterogeneous features of the rock mass play also an important role. It is proved by insertion of thick rock bars in the structure or varying rock block sizes in the mass. These models modified considerably the stress distribution and the deformation distribution. Finally, we have analyzed the influence of mechanical parameters such as friction angle and tangential stiffness.

Scratch-based programming has come to be known as an effective programming tool because of its graphic instruction modules, which are designed to be assembled like the famous LEGO building blocks. These building block-like structures allow users to more easily program applications without using other more difficult programming languages such as C or Java, which are text-based. Therefore, it poses a good opportunity for application in educational settings, especially in primary schools. This paper presents an effective approach to developing an educational robot for use in elementary schools. Furthermore, we present the method for scratch programming based on the external modules need for the implementation of robot motion. Lastly, we design a systematic curriculum, titled "Play with a Robot," and propose guidelines to using the educational programming language Scratch.

Objectives: This paper aims to suggest some ways we could improve the efficiency and equity in health promotion programs in the public sector. Methods: Reports published by the Minister of Health and Welfare and web-site information were reviewed. And, the empirical results and theoretical considerations provided in this study could be used in making future direction for health promotion programs in the public sector. Results and conclusion: The public sector should play a leading role in health promotion programs. The role of public sector in health promotion program is to establish the health promotion plan based on the health survey, to develop the scientific programs, to provide the free health services, and to maintain a cooperative relationship with the private sector. In order to activate the health promotion programs in the public sector, establishing the role of the public sector, changing the operation of health promotion fund, block grants for health promotion, local health promotion fund, and integration of health statistics were suggested.

최근에 영상 및 음성 데이터의 양은 크게 증가하고 있다. 이러한 경향에 따라 고밀도 자기기록 시스템이 필요하게 되었고 테이프의 트랙은 더욱 더 좁아지게 되었다. 따라서 DVCR(digital video cassette recorder)에서는 재생시에 캡스탄 모터의 속도와 위상을 정밀하게 제어하여, 헤드가 트랙을 따라 정확하게 주행하도록 유지시켜주는 캡스탄 서보시스템이 필요하게 되었다. 이를 위하여 DVCR에서는 ATF(Automatic Track Following)방식을 사용한다. 본 논문에서는 이산 푸리에 변환(discrete Fourier transform)을 이용한 새로운 DVCR용 ATF 블록의 설계방법을 제안하였다. 제안한 ATF 블록을 ALTERA사의 FPGA에 구현하여 실제 DVCR 시스템에서 그 성능을 시험하였다. 실험을 통하여 본 논문에서 제안한 방식이 기존의 디지털 저역통과필터(lowpass filter)를 사용한 구현법에 비해 비용면에서 더 효과적임을 검증하였다. 또한 로직게이트 수가 기존의 방법에 비하여 약 20% 감소함을 확인하였다.

최근, 3D FPS 게임에서 캐릭터의 분류는 매우 중요한 문제로 떠오르고 있다. 본 연구에서는 간단한 조작으로 의미객체의 화상 영역 분할을 이용한 게임 콘텐츠 분류 방법을 제안한다. 이 방법에서는, 우선 비선형 RGB 컬러 모델과 컬러양자화 방식을 사용했다. 입력 화상은 20개 미만 양자화 된 색을 표현하고 의미 있는 적은 수의 컬러 히스토그램을 사용한다. 그리고, 적은 블록으로 분할 된 이미지는 블록 단위 컬러 히스토그램 교차로 인접 블록과의 유사도를 계산한다. 왜냐하면, 질감 및 대상 블록의 경계에 있어서, 추출 블록 경계를 제외한 나머지를 사용하기 때문이다. 게임 오브젝트는 이들 방법에 에 의해 블록 경계 영역을 설정하고 FPS 게임 플레이에 사용될 수 있다. 실험을 통해, 우리는 각각의 기능을 사용하여 분류 방법에 대해 80% 이상의 정확도를 얻을 수 있었다. 따라서, 이 특성을 이용하여 게임콘텐츠를 효율적으로 분류 할 수 있고, 이는 게임 속도와 전략적 행동에 보다 나은 결과를 초래할 것으로 예상한다.

This study carried out to understand the thermal characteristics of various surface material which compose the city through the observation in the summer. To examine passive cooling effect of planting of building, it is arranged four different materials that is natural grass, grass block, concrete slab and artificial grass. The results of this study are as follows; (1) Natural grass and grass block show the lower surface temperature because of the structures of leaf can do more thermal dissipation effectively. (2) There is little surface temperature between artificial grass and concrete. But there is little high surface temperature difference between natural grass and concrete because of latent heat effect. (3) The concrete can play a role of the tropical nights phenomenon as high heat capacity of concrete compare with other materials. (4) It is nearly same color in artificial grass and natural grass but there is large difference between natural grass and artificial grass at albedo. There is different albedo in near infrared ray range. (5) A short wave radiation gives more effect at the globe temperature than long wave radiation. (6) The artificial turf protected the slab surface temperature increase in spite of thin and low albedo materials.
