Sam-Gye-Je('Sam' means as three, 'Gye' as chinese scholar tree, and 'Je' as a house for a sacrificial rite), located in Tae-Chung-Dong, Kyungsan City, Kyungbuk, is a traditional landscape element that contains features of Je and menhir together. The object of this study is to identify a background of constriction and to analyze meanings and charateristics of the structure. To achieve these objectives, this study has conducted a literature review, an analysis of Gimun(a description of history, landscape or meaning about Je) and photograph, and a level survey. Conclusions derived from these analyses are as follows : 1. About 250 years ago, Chung-Tae-Woon who lived in Taegu, came to the Chung-Dong. He built Sam-Gye-Je where three chinese scholar trees(Sophora japonica L.) stood, followed by Jung-Lya-Goak(a monumental house of dutiful son) in 1855. It is postulated that there were three menhirs when the Sam-Gye-Je was built. 2. It is postulated that the menhir Ⅰ, Ⅲ, Ⅴ were built in Silla Dynasty or before, but it is difficult to conclude that they were built at the same time. It is because that some variations are found in the shape, the weathering state, and kind of the rock. 3. It is postulated that the Menhir Ⅱ and Ⅳ were built in 1855, it is believed that the statues were built to inherit the ancestors' high aim and life(loyalty and filial piety) to their decedants. 4. It is hard to conclude that incisions on the menhir were concurrent. However, contents of the incisions have a strong connection with the meaning of the Je, particularly in the V-menhir. Also menhir Ⅰ and Ⅴ reflected a meaning of elegance, considering the surrounding landform. 5. It is very unique to build the menhir at the Je. Furthermore, it is very interesting to arrange 5 menhirs in one line, even though they were not built at the same time. 6. The origin of the menhir and other details that is not disclosed in this study should be followed by a further research.

이동하중에 대한 열화교좌교량의 거동분석

이계희 木浦海洋大學校 2004 論文集 Vol.12 No.-

본 논문에서는 열화된 교좌장치를 가진 단경간 철도교량의 이동하중에 대한 거동특성을 분석하고 교좌장치의 열화에 대한 영향을 평가하였다. 고려된 교좌장치의 열화특성은 마찰의 증가, 종방향 유간의 부족, 회전유간의 부족이며 각각의 열화특성을 모델링하고 동적비선형 해석을 수행하였다. 차량에 의한 활하중은 이동하중(Moving Force) 방법을 이용하여 고려하였으며 5개의 주행속도에 따라 교량모델의 제원을 기준으로 작성된 시간함수를 산정하여 구조물에 작용시켰다. 해석결과 동적하중에 의한 거동에 미치는 마찰계수의 영향은 크지 않은 것으로 나타났다. 또한 종방향, 회전유간의 부족도 경간중앙의 응답에 대해서는 그 크기를 약간 감소시킬 뿐 큰 영향을 미치지는 못하는 것으로 나타났다. 그러나 종방향, 회전유간의 부족은 지점부에 큰 모멘트와 축력을 방생시키며 이 때 발생하는 부재력은 경간중앙부에 비해 3~4배의 큰 충격계수를 보여 정적해석을 통한 검토시 주의가 필요한 것으로 나타났다. In this paper, the behavior of simple span railway bridge with deteriorated bearings for moving loads are presented. The increase of friction, the insufficient of expansion space, the insufficient of rotational space are considered as the deterioration characteristics of bearing. These characteristics are modeled nonlinear boundary and nonlinear dynamic analysis performed. The live loads are modeled as moving force time histories, which are generated for five different speed of loading, with consideration of configuration of bridge model. The analysis results show that the effect of friction increase to bridge behavior for moving load is not severe. And the effects of the insufficient of expansion space & the insufficient of rotational space for mid-span responses are also limited in decreasing of the values of those. However, these deterioration characteristics produce the unexpected member force, such as the end moment and the axial force, at ends of span. Especially, these member forces show the 3-4 times of larger value of impact factors than those of mid-span, the structural estimation of these type of deterioration by static analysis must be performed with careful consideration.

This research was undertaken in order to obtain the basic data for systematical pig management through of pig analysis of current status of raising pigs, wholesale price, the appearance ratio of carcass grade, consumption of pork, the number of pigs imported and exported during about 10 years in Korea. These data were collected and analysed from recent secondary raw data. The results obtained were abstracted as follows; 1. The number of raising pigs have tendency to increase gradually with about 8,371,000 pigs, while the number of farm household have tendency gradually to decrease with 24,000 household on September, 2000. Accordingly, the farm sizes are changing with large scale of average of 349 pigs. 2. The farm price of alive pig at 100㎏ was high level with 199,000won in 1999. The carcass price per 1㎏ was the average of 2,982won in 1999. The pork was consumed much more in summer season. 3. The total of meat consumption per capita have been increasing with 30.54㎏ in 1999. Out of total meat, pig meat was 53%. 4. The live pigs imported had been increased gradually up to 1997, however, decreased with 410 heads in 1998. The pigs imported have been mainly utilized as effective breeding animals. 5. The pork imported has been showing rapid increment since 1997. Otherwise, the pork has been gradually decreased with 55,684ton in 1998.

부분 안정화 지르코니아 소결체(12 wt% Y-PSZ)를 열처리함으로 나타나는 정방정 지르코니아(t'과 t-지르코니아)의 미세구조를 투과 전자현미경으로 관찰 하였다. 1400℃ 이상의 온도에서 열처리 한 후 상온으로 급냉시키면, t'-정방정이 나타나는데 이상은 yttria 양이 원래의 조성과 비슷하고, 미세구조상에서 90˚쌍정이 특징적이며, 각각의 90˚쌍정 안에 antiphase domain boundary(APB)가 존재하는 미세구조를 보였다. t'-지르코니아는 고온에서 불안정하여 1400℃에서 열역학적 평형상인 입방정과 t- 지르코니아로 분해되었다. 미세한 t-지르코니아는 고온에서 성장하여 정방정상으로 자라 특정 방향으로 배열되었다. Sintered yttria-partially-stabilized zirconia(12wt% Y-PSZ)was investigated using TEM, focused on the microstructural evolution of tetragonal phases by heat treatment. When the specimens, which had been heat treated above 1400℃, were quenched to room temperature, t'-phase was abserved. This t'-phase was characterized by its higher yttria content, 90˚twins and APB's within each twin. T'-phase was unstable to high temperature and was decomposed into thermodynamic equilibrium phases ; t-ZrO₂ precipitates and cubic phase below 1400℃. Small tetragonal zirconias grew into rectangular-shaped precipitates at higher temperature and were aligned in specific directions.

게임놀이훈련이 자폐성 아동의 사회적 상호작용 행동에 미치는 효과

박계신 한국초등특수교육학회 1999 초등특수교육연구 Vol.1 No.1

본 연구는 게임놀이훈련이 자폐성 아동들의 놀이, 대인관계, 행동적 측면에 미치는 효과를 밝히고자 하였다. 연구 대상은 이 세 가지 영역에 있어서 사회적 상호작용 가능성이 낮고 빈도가 매우 적으며 고집성, 자해행동, 자기자극행동과 같은 부적절한 행동을 나타내는 3명의 자폐성 아동들이다. 사용된 게임놀이훈련은 의자 않기 게임, 색 찾기 게임, 장애물 게임으로 각 게임은 개별 게임 훈련 시기, 집단 게임 훈련 1기, 집단 게임 훈련 2기의 3단계로 구성되었고 비자폐성 아동과 집단을 이루어 훈련이 수행되었다. 연구의 결과는 게임놀이훈련은 자폐성 아동의 놀이 및 대인관계영역에 있어서 사회적 상호작용 기술을 향상시키는데 효과적이었으며 행동 면에 있어서 부적절한 행동들을 감소시키는데 효과적임을 밝혔다. It is well accepted that autistic children has not only considerable difficulty with normal social interaction behaviors and peer interaction but also defect in playing with others. difficulties with social development and problems with social relationships are hallmark of autistic children and this pervasive developmental disorder is also severe behavior disorder. The main purpose of the present study was to investigate how game training affects social interaction behaviors of autistic children. Three autistic children who had problems in the social interaction behaviors including play, personal relations and behaviors were selected as the subjects of this study. Their chronological age range was 8 to 9 years of age. The subjects participated weekly in the game training for 6 months. The game training include three games, such as sitting chair game, color searching game, and barrier game. Each game was composed of three phases including individual game training period. The following results were obtained from the study: First, the game training improved three children's play with other children and adults. During the training, an increasing frequency of plays was occurred to only two of three subjects, but one remained unaffected. Second, the game training improved three children's relationship with their siblings and other children. Two children improved in the relationship with their parents, but one made no significant improvement. Third, the game training decreased three children's inappropriate behaviors, such as insistence on the sameness, tantrum, self-injured behavior, while it increased following instructions, spontaneity, concentration, adaptative and spontaneous behavior to the group. It was discussed in the study that autistic children experienced a variety of games and play materials in play. Finally they could initiate play for themselves and respond to others demands for play, that autistic children might have more interests in other people and increase the initiation of social interaction and responses to other's demands, as they became competed and cooperated with playmates through the game training, and that autistic children's inappropriate behaviors might be decreased and their adaptive behaviors might be improved, as they became aware of game rules and played with rules.
