This study simulated strong ground motion waveforms in the southern Korean Peninsula, based on the physical earthquake modeling of the Southern California Earthquake Center (SCEC) BroadBand Platform (BBP). Characteristics of intensity attenuation were investigated for M 6.0-7.0 events, incorporating the site effects. The SCEC BBP is software generates broadband (0-10 Hz) ground-motion waveforms for earthquake scenarios. Among five available modeling methods in the v16.5 platform, we used the Song Model. Approximately 50 earthquake scenarios each were simulated for M 6.0, 6.5, and 7.0 events. Representative metrics such as peak ground acceleration (PGA) and peak ground velocity (PGV) were obtained from the synthetic waveforms that were simulated before and after the consideration of site effects (VS30). They were then empirically converted to distribution of instrumental intensity. The intensity that considers the site effects is amplified at low rather than high VS30 zones.

The grade of East Asian architecture is generally classified by the size, the shape of the roof, and the type of bracket set. The craftsmanship of columns, beam, purlin, stylobate, column base stone and paintwork is also a contributing factor for such classifications. These classifications can be found not only in historical documents such as Oksajo(屋舍條) of Samguksagi(三國史記) but also in house details regulations of residential architecture(家舍規制) of Joseon Dynasty. However, there are differences in detailed designs among the same grade of architecture regardless of the classification. In this research, the Palace, the Royal Residence(宮家), and the Jaesil(齋室) are considered as the Palatial Buildings and Royal Residences. And the advanced architectural ㅇ details which appear only in the Royal Architectures are defined as the ‘The Architectural Crafts as a Code of Manners’. The Architectural Crafts as a Code of Manners is detailed design, which can be seen as fabrication of materials and supplementary factors. The Architectural Crafts as a Code of Manners used in the Palatial Buildings and Royal Residences reveal the types and their historical changes. This research will present a basis for the repair and restoration of cultural heritages to be carried out in the future, and also prevent them from further damages, thus help to preserve the cultural heritages.

목적 : 본 연구는 베일리 영유아 발달검사 3판 대근육 운동척도를 한국판(Korean-Bayley-Ⅲ; K-Bayley-Ⅲ)으로 타당화하기 위하여 문항분석과 신뢰도 및 타당도를 검증하고자 하였다. 연구방법 : 본 연구의 참여자는 생후 16일에서 42개월 15일의 영유아 1,764명으로, 지역 및 성별, 모의 학력에 따라서 층화 표집되었다. 문항분석을 위하여 문항반응이론에 근거한 문항 난이도 분석과 고전검사이론을 통한 문항 통과율을 분석하였고, 신뢰도를 검증하기 위하여 반분신뢰도를 이용한 내적일관성, 검사-재검사 신뢰도, 평정자간 일치도를 살펴보았으며, 상호상관검증을 통해 수렴타당도와 변별타당도를 확인하였다. 결과 : 첫째, K-Bayley-Ⅲ 대근육 운동척도의 난이도를 조사한 결과, 총 72개의 문항은 원척도와 유사하게 쉬운 문항에서 어려운 문항까지 비교적 순차적으로 배치되어 있었다. 또한 시작점과 기저선 문항의 적절성을 알아보기 위하여 월령 단계별 문항 통과율을 확인한 결과, 대부분의 월령 단계에서 시작점과 기저선 문항이 적절한 것으로 나타났다. 둘째, 척도의 신뢰도 분석 결과, 대부분의 월령 단계에서 문항 내적일관성이 높은 것으로 나타났으며, 검사-재검사 신뢰도 및 평정자간 일치도도 높은 것으로 확인되었다. 마지막으로 타당도 검증 결과, 대근육 운동척도는 운동척도와는 높은 상호상관을 보인 반면 언어척도와는 중간 정도의 상호상관을 보여 수렴 및 변별타당도가 확보되었다. 결론 : 본 연구를 통해 K-Bayley-Ⅲ 대근육 운동척도가 한국 영유아의 대근육 운동발달을 평가하는데 타당하고 신뢰로운 척도임이 입증되었다.

경피경간담즙배액술은 담석, 양성협착, 악성종양 등에 의한 폐쇄성 황달을 감압시키기 위한 방사선학적 방법이다. 담관을 통한 담즙의 내부배액이 회복되면 경피경간담즙배액 도관은 경피적으로 제거할 수 있다. 본례에서는 병상에서 경피경간담즙배액 도관을 제거할 때, 도관이 복강으로 이동하여 복막염이 발생하였고 경구내시경으로 도관을 제거하였다. 경피경간담즙배액 도관을 제거할 때는 도관이 복강으로 이동하지 않도록 주의하여야 하며, 부주의로 인하여 도관이 복강으로 이동하였을 경우에는 경구내시경으로 도관을 제거할 후 있다.

Probiotics is known improve the microenvironment of colon; however, the metagenomic DNA study of its lactic acid bacteria in constipation induced by loperamide is not clearly understood. In the present study, we investigated the reduction of the lactic acid bacteria in case of constipation, in normal and loperamide-induced rat. Lactic acid powder (lactic acid bacteria 19) was prepared from Chong Kun Dang Pharmaceutical Corporation. After 2 weeks of oral administration, the group treated with the higher concentration of lactic acid bacteria (109 CFU/mL per kg of body weight) following loperamide treatment was the most effective in increasing number, weight, and water content of feces. A similar but significant increase was found in the group treated with lower concentration of lactic acid bacteria (107 CFU/mL per kg of body weight) after loperamide treatment. The concentrations of acetic acid and propionic acid in feces in the loperamide-induced rat with high concentration lactic acid, were significantly higher than that of others. Furthermore, gastrointestinal transit ratio as well as the length and area of intestinal mucosa were significantly increased after treatment with lactic acid bacteria in loperamideinduced rat. Metagenomics DNA analysis indicated that the microorganism homology in cecum was similar between the groups of normal (NOR) and HIG. Our results show that lactic acid bacteria were effective in improving the constipation.

This study was performed to estimate the salt content and evaluate the nutritional quality of free lunch meals served by welfare facilities for the elderly. We collected food items from 8 welfare facilities in Gyeonggi-do, and calculated the total salt content from the salinity and weight of individual food items. The average salt content from lunch meals was 5.68 g, which was over the recommended daily salt intake by the WHO. The greatest contributor to the salt content among the menu groups was soup and stew (37.5%). Soup, stew, deep-fried foods, and sauces were major sources of salt, while the most salty dishes were sauces, deep-fried food, salt-fermented food, and kimchi. The nutrient content was sufficient, except for calcium in both men and women, which was equal to approximately 1/3 of the dietary recommended intakes (DRIs) for Korean adults of their mean age. In addition, the index of nutritional quality (INQ) and nutrient adequacy ratios (NAR) of most nutrients were satisfactory, except for those of calcium and sodium. The INQs of calcium and sodium were 0.64 and 4.41, respectively, while the mean adequacy ratio of a meal was 0.95. These results suggest that multilateral efforts to lower sodium intake be considered and calcium sources be added, in order to improve the quality of meals served to the elderly at welfare facilities.

기존 구내 치근단 촬영용 장치는 환자 피폭선량, 촬영시 고통 등의 문제점을 지니고 있다. 본 연구에서는 이러한 문 제점을 해결하기 위한 신개념의 삽입형 초소형 X선 시스템의 가능성을 검증하였다. 먼저 초소형 X선 튜브에 사용될 콜리메이터와 필터를 설계하기 위하여 Geant4를 이용하여 최적의 콜리메이터 두께와 필터 두께를 결정하였으며 CdTe 검출기와 PX4 모듈을 이용하여 결정된 두께에서의 X선 스펙트럼을 확인하였다. 또한 기존 상용화된 치근단 촬영장치 와 XOFT사의 초소형 X선 튜브를 이용하여 제작된 치아 팬텀에 대한 영상을 획득하였다. 그 결과 제안된 신개념의 삽 입형 초소형 X선 시스템은 기존 시스템과 유사한 영상의 질을 나타내었다. 이는 향후 치근단 촬영용 장치를 비롯하여 다양한 응용부위에 활용할 수 있음을 나타낸다.
