본 연구는 투자유치국가에서 행해지는 다국적기업의 기업시민행동에 대해, 전략적 요소 및 제도적 환경이 미치는 효과를 고찰한다. 한국에 상주하는 199개 다국적 기업을 분석한 결과, 다국적 기업의 기업시민행동은 투자유치국-투자모국간의 제도적 환경 차이에는 별다른 영향을 받고 있지 않지만 전략적 요소, 즉 소유 집중도 및 국제화 동기 차원과는 관련성이 크다는 것을 알 수 있다. 특기할만한 점은, 다국적 기업의 구체적인 기업시민행동 (예를 들면, 환경차원의 활동)은 투자모국의 제도적 여건에 의해 더욱 촉진되고 있음을 알 수 있다. 본 연구를 통하여, 우리는 투자유치국가에서 행해지는 다국적 기업의 시민행동은 자원몰입의 정도 및 그들이 직면한 제도의 효과성에 의해 영향 받고 있음을 제시한다.
The building for the Sutra appeared as the Sutra-belief became popular in the early years of the Koryo Dynasty. According to the written documents, there were two types of apparatus to keep sutras, one by fixing the cabinet to the wall and the other by rotating the cabinet at the center of the hall. There are no remains. Recently, at the excavation of the site of the Yeongguk Temple (寧國寺) in the Chungcheong Prevince (영동군), a building which was presumed as the Sutra Hall was recovered at the side of the Main Hall. At the center of the building, of 6meters width and 6meters depth, there was a large stone which had a round trace which was presumed to supporting the rotating sutra-case cabinet. By examining the concerned situations, this building was concluded as the Sutra Hall of the temple. The Yeongguk Temple had a close relationship with the royal household. Budddhist monk Gwangji, son of the 16th King Yejong was lived at the Temple. the tomb of King's advisory priest Wongak was also erected at the Temple. Two monks were well known as the defender of the Sutra. The Sutra Hall of the Yeongguk Temple regarded as a significant example which showed us how the archtectural aspect of the Sutra Hall was shaped in the Koryo Dynasty. It could be said that revealing the architectural aspect of the Stura Hall will help revealing the Buddhist architecture of the Koryo Dynsty which is veiled in many field.
The conversion of coal fly ash into zeolites contributes to the mitigation of environmental problems and turns this by-product into useful material. In this work, zeolitic sorbents for CO2 adsorption were prepared by waste fly ash from Boryeong coal power plants through the alkali fusion method including hydrothermal treatment at various ratios of NaOH/FA and NaAlO2/FA. In addition, in order to improve the adsorption capacity for CO2 molecules a few metal cations were impregnated into the synthesized zeolitic sorbents through the ion exchange. The fusion step could decompose the fly ash to very small amorphous particulate zeolite forms. The fly ash was converted into Na-P1 type with 0.5 NaOH/FA and Na-A type from the ratio of 0.53, NaAlO2/FA. Although the crystallinity of Na-A increased with increasing temperature, Na-A was transformed into sodalite at 140℃. Thus, the optimum reaction temperature was determined to be 100℃. Alkali metal and alkaline earth metal cations were impregnated into the synthesized zeolite Na-P1 and Na-A through ion exchanged method. The completed zeolitic sorbents were applied to adsorption the CO2. As a result of the examination, Ca2+ was found to be the best for CO2 adsorption owing to its electrostatic interactions and acid-base surface properties.
본 논문은 Keller의 ARCS 모델을 기반으로 하는 유아 대상의 수학교육 CAI 프로그램 설계를 제안한다. 이를 위해 본 논문은 NCTM의 다섯 가지 영역 중 수와 연산 영역, 기하 영역, 자료 분석과 확률 영역에서 색, 수 세기, 도형, 방향을 포함한 수학 교육 CAI 프로그램을 개발하였다. 수학 교육 CAI 프로그램은 유아가 직접 카메라를 사용하여 RGB를 이용한 색 인식, 윤곽선 근사화와 허프변환을 이용한 도형 인식, 색 위치 기반의 방향 인식에 대한 미션을 수행하면서 학습하게 해 게임 몰입을 유도한다. 또한 동물형 캐릭터와 캐릭터가 제시하는 미션을 수행하게 함으로써 유아의 흥미를 유발하여 주의를 집중시키고 유아 스스로 학습과 생각할 수 있게 해 학습을 하면서 미션을 성공이나 실패시에 캐릭터의 칭찬과 격려를 통해 자기 효능감을 높이고 자신감을 가질 수 있는 환경을 제공한다.
인간의 언어 발달상 36~60개월의 아동은 언어적으로 복잡해지며 문법이 발달하는 시기로 이 시기에 적절한 청능훈련을 하지 않으면 정상적인 언어 발달이 어렵다. 기존 청각 장애 아동을 위한 청능훈련은 오프라인 상에서 음악, 미술, 놀이 훈련 등 다양한 분야의 프로그램들이 있다. 청각 장애 아동의 특성상 청각적 자극을 위해 반복적이고, 지속적인 청능훈련이 필요하다. 하지만 기존의 청능훈련은 시간, 공간 제약적이며 전문 인력의 부족과 다양한 프로그램의 부재로 청각 장애 아동의 지속적인 청능훈련에 제약이 있다. 본 논문은 기존의 청능훈련의 한계를 극복하고 청각 장애 아동의 특성에 맞는 청능훈련 멀티미디어 시스템을 제안하고 설계한다. 청능훈련 멀티미디어 시스템은 CAI(Computer Assisted Instruction)개념을 토대로 설계하고, 청각 장애 아동의 청능훈련 향상을 위해 Keller의 ARCS이론의 요소들을 청능훈련 멀티미디어 시스템에 포함한다.

The study on Buddhism architecture in early Joseon dynasty was inactive. The period of King Sejo is important for studying the trend of Buddhism architecture in early Joseon, that was transmitted from the end of Goryeo dynasty, but it was difficult to know its exact situation due to lack of related records. The records were all written by Kim Su-ohn, which are Wongaksabi' 'Sangwonsajungchanggi' 'Bongseonsagi 'Geonginsajungchanggi'. The main hall was mainly second floor and there were necessarily annexed buildings at the right and left of the main hall. So the plane figure of □□□ was shown. It was a main stream for monk's living hall and meditation hall to be located at the right and left of yard in front of main hall. This layout may be referred to search for the origin of the layout in courtyard based structure(中庭形) in the late Joseon dynasty. Most of temples had 3 gates. Some part of horizontal corridor was used as 2 gates and the outer gate, far from main hall, was without corridor. The gate leading to front yard of main hall was called front gate, the next was middle gate and the outer gate was Oisamun(外沙門 )or Samun(沙門). In most of the temples, people could enter into the front yard through pavilion which had the function of bell tower. The pavilions were located between front gate and first corridor. It is thought that this layout of the place for making bean curd outside the temple area will contribute to different studies on temples making bean curd in the future. The records about temple's foundation studied above are a little different between temples, but have more similarities. These common denominators represent the architecture tendency of Buddhist temples in the related period. It is thought that such a tendency was also shown on architecture of other temples during the reign of King Sejo as well as Buddhist temples.
In this work, pellet type sorbents were prepared to control the low level indoor carbon dioxide with various physical compositions. In order to enhance the adsorption capacity, a few additives including alkali hydroxides were added to a commercial zeolitic sorbent by impregnation of alkali cation - Ca2+ through physical mixing and ion exchange. It was found that the binding materials such as dextrin or bentonite facilitating to form the granular sorbents would assist the adsorption capacity of sorbents. The ion exchange was more efficient for impregnation of alkalies, which showed better adsorption of gaseous CO2.
This paper aims at studying on the medium of cultural interchange regarding who did and how to introduced the new trend of architecture during the period of Koryo Dynasty. Before the era of Koryo Dynasty, Kyungjang(Sutra Pitaka, 經藏) was mainly centered in Kyeongnu with a substantial function of storage. In the early Koryo Dynasty, however, Daejangjeon(大藏殿), which was spatialized for worship, began to appear. Normally, fixed walls were installed and the Sutras were enshrined inside Daejangjeon, while Jeonryunjang (revolving wheel sutras), a type of rational bookshelf, was introduced, and a new trend became developed in Kyungjang construction. Jeonryunjang(revolving wheel sutras, 轉輪藏) is a dharma instrument with a rotational function so that one revolution gives an effect of reading the enshrined Sutra one time, and began to be created actively in the period of the Northern Song. It is considered that the introduction of Jeonryunjang(revolving wheel sutras) to Daejangjeon was resulted from Haejokuksa(慧照國師) Damjin(曇眞) who visited the Kangnam areas in the Northern Song at that time. The Kangjeol areas in the Northern Song, where Damjin concentratively itinerated three times, were the place in which Jeonryunjang was created in many temples. Since Damjin, historical materials and excavated data regarding constructing Jeonryunjang have been discovered in the Buddhist temples, which are related to his pupils and dharma lineage. The only existing Jeonryunjang of Yongmusa Temple in Korea is the one that Joeung Daesunsa, who succeeded to the dharma lineage of Haesokuksa, promoted, and supports strongly such introduction of Jeonryunjang by Haesokuksa
To improve the efficiency of in vitro production of embryos with follicular oocytes in Korean Native cows, the recovery rates, in vitro maturation, fertilization and development, and the time required for collecting and processing oocytes by aspiration with or without slicing were evaluated comparatively. The ovaries were obtained from a local abattoir and placed in physiological saline at 25~28 and brought to the laboratory within 3 hrs. The oocytes were collected by aspiration of follicles(2~6mm) with or without slicing ovaries after aspiration, and classified into Grade I, Grade II, Denuded, Expanded oocytes by the morphology of cumulus cells attached and the homogeneity of cytoplasmic granules. Also the time required for each step of collecting and processing oocytes were measured. The cumulus cells were removed in some Grade I oocytes to measure their size and nuclear configuration before and after in vitro maturation. The Grade I oocytes were matured in vitro(IVM) for 24 hrs. in TGM-199 supplemented with 35g /ml FSH, 10g /ml LH, 1 g /ml at 39 under 5% C02 in air. They were fertilized in vitro(IVF) by epididymal spermatozoa treated with heparin for 24hrs. and then the zygotes were cocultured in vitro (IVC) with bovine oviductal epithelial cells for 10 days. The results obtained were as follows: The number of oocytes recovered per ovary was averaged 6.6 by aspiration and 11.2 by slicing post aspiration, which summed to 17.8. The number of Grade I oocytes recovered per ovary was averaged 3.1 by aspiration and 3.6 by slicing, which summed to 6.7. The percentage of Grade I to total oocytes recovered was significantly(P<0.05) higher as 48.0 % in aspiration than 31.6% in slicing post aspiration. The time requlred for recovering a Grade I oocyte by aspiration and slicing was 1.1 and 2.5 min, respectively. The mean diameter of Grade I oocytes by aspiration and slicing was similar as 148.7 and 151.5m, respectively. The percentage of Metaphase II stage oocytes after IVM for 24 hours was significantly (P
서울, 충청도 및 강원도 지역의 김장김치 담금방법을 알고자 203개 가정에서 설문조사를 한 결과 3지역에서 김장김치류중 배추김치는 95%이상 남았는데 배추선택시 결구도를 가장 중요시 하였다. 배추는 천일염을 주로 사용하여(66∼78%)소금물에 적신 후 다시 소금을 뿌려 약 7∼10시간 동안 절였다. 김치숙성시 서울과 충청도는 배추상태가, 강원도는 양념이 가장 큰 영향을 미치는 것으로 인식되었으며 김치보관은 70%이상이 김치 항아리를 이용하였는데 김치보관용기와 주거형태(단독 및 아파트)간에는 x^2=49.87(P<0.000)로 유의적인 관계가 있는 것으로 밝혀졌다.
The purposes of this study were to produce cloned rabbit embryos and offsprings by nuclear transplantation(NT) using in vitro matured oocytes as nuclear recipient cytoplasm and to determine the effect of frozen nuclei donor embryos on the production efficiency of cloned embryos. The 8cell embryos were collected from the mated does by flushing oviducts with Dulbecco's phosphate buffered saline containing 10% fetal calf serum(FCS) at 40 hours after hGG injection. A portion of collected embryos were preserved at 4 for 24 hours and a portion of them were frozen by vitrification method. The embryos used for donor nuclei were synchronized in the phase of Gi /S transition. The in vitro matured oocytes were used as recipient cytoplasm following removing the nucleus and the first polar body. The synchronized blastomeres from fresh, cooled or frozen embryos were injected into the enucleated oocytes by micromanipulation and were electrofused by electrical stimulation of three pulses for 60 sec at 1.0 W /cm in 0.28 M mannitol solution. The fused oocytes were co-cultured with a monolayer of rabbit oviductal epithelial cells in M-199 solution containing 10% FCS for 120 hours at 39 in a 5% incubator. Following in vitro culture of the NT embryos to blastocyst stage, they were stained with Hoechst 33342 dye for counting the number of blastomeres by fluorescence microscopy. The nuclear transplant embryos developed in vitro to 2- to 4-cell stage were transferred into the oviducts of synchronized recipient does. The results obtained were summarized as follows: 1. The fusion rates of the blastomeres from fresh, cooled and frozen embryos with the in vitro matured and enucleated oocytes were 100, 95.8 and 64, 3%, respectively. 2. Development in vitro to blastocyst was significantly(p<0.05) different between the cloned embryos with the blastomeres from fresh, cooled or frozen embryos as 39.0, 20. 9 and 15.7%, respectively. 3. The mean numbers of cell cycle per day during in vitro culture of cloned embryos blastomeres from fresh, cooled or frozen embryos was 1.31, 1.29 and 1.16, respectively. 4. A total of 77 nuclear transplant embryos were transferred into 6 recipient does, of which two offsprings were produced from a foster mother 31 days after embryo transfer.
