Hydraulic property of fissured aquifers often depends on geologic structure which acts main channel of groundwater flow. We treated theories of linear flow related to vertical geologic structure. Then, we analyzed the result of two pumping tests conducted in Okmyeong-ri area (Kyeongbook province) using fractal model and found hydraulic characteristic of the fissured aquifer in this area. According to the pump test analyses, groundwater flow around the holes (pumping well D9; observation wells C3 and D7) of test 1 is linear. and is controlled by vertical geologic structure with infinite length and infinitesimally small width. On the other hand, around the hole D10 (pumping well) of test 2, groundwater flow is pseudo-radial (n=1.9) or radial (n=2). Thus, the characteristic of fractured aquifer often shows variable groundwater flow spatially and temporally.

This study verified the effects of promoting optimism by utilizing communication board games with university students. Since optimism is closely related to grade, self-efficacy, a sense of achievement, the importance of enhancing optimism was emphasized. This study seeks to investigate practical measures that can promote optimism utilizing games in a more casual environment based on the research of Seligman(1990), which claimed that the optimism can be learned regardless of temperaments. In Study1, the level of optimism increased from M=-4.7(t1) to M=12.8 in t2(p<.001). In Study2, a control group(n=22) was added with the experiment group(n=21). The level of optimism increased from M=-2.4(t1) to M=11.5(t2) in the experiment group(p<.001), whereas there was no difference in the control group.

Lysine residues of histone H3 and H4 are covalently modified in the chromatin of eukaryotic cells. Lysine 27 in histone H3 was acetylated (H3K27ac) or methylated at three levels; mono-, di-, and trimethylation (H3K27me1, H3K27me2, and H3K27me3). These modifications at H3K27 were related with gene transcription and/or chromatin structure in distinct patterns. Generally, H3K27ac and H3K27me1 were enriched in active chromatin, such as the locus control region or transcriptionally active genes, while transcriptionally inactive genes were highly marked by H3K27me2 and H3K27me3. These modifications appear to have been catalyzed by distinct histone-modifying enzymes. Recent studies suggest that the four kinds of modifications at H3K27 have inter-correlation in gene transcription or chromatin structure formation.

민속식물과 그 이용에 관한 전통지식이 산업화, 도시화 및 노인 세대의 퇴장과 더불어 빠르게 사라지고 있다. 이에 본 연구는 민속식물 주권확보 기반구축을 위하여 2005년부터 2017년까지 1차(2005~2013), 2차(2014~2017)에 걸쳐 남한 전역 및 함경북도 접경지역을 대상으로 각 지역에서 전통적으로 이용해왔으며 전승되어 온 민속식물 관련 전통지식을 발굴 및 수집하였다. 민속식물 중 약용으로 사용된 것은 121과 383속 583종 3아종 64변종 12품종으로 총 662분류군으로 확인되어 식용 다음으로 큰 비중을 차지하였다. 이는 한반도 전체 관속식물 4,881분류군의 약 13.6%에 해당하며, 총 115,236건의 조사된 전통지식 중 17.9%를 약용이 점유하여 식용(67.2%) 다음이며 용재용(4.9%), 유지용(2.5%), 관상용(1.3%) 등에 비하여 상당히 높게 나타났다. 662분류군 중 자생식물은 511분류군(77.2%)으로 나타났고, 생활형은 다년생 초본이 295분류군(44.6%)으로 낙엽성 목본(186분류군), 1년생 초본(78분류군) 등 타 생활형에 보다 높았다. 약용식물의 이용부위는 뿌리(34.1%)가 가장 많았고 그 다음으로 줄기(16.2%), 잎(15.4%), 열매(12.1%), 전초(12.1%), 수피(3.2%), 종자(2.4%), 꽃(1.9%) 등의 순으로 나타났다. 우리나라에서 이용빈도가 높은 상위 10개 분류군을 살펴보면 익모초, 쇠무릎, 인동덩굴, 느릅나무, 삽주, 엉겅퀴, 쑥, 질경이, 오갈피나무, 할미꽃 등의 순으로 조사되었다. 본 연구에서는 민속식물의 이용에 대한 중요도를 알아보기 위하여 특정식물 종의 이용을 언급한 정보보유자의 수(FC: Frequency of Citations), 이용범주의 수(NC: Number of use-Categories), 특정식물을 이용하는 수(UR: number of User Reports)를 활용하여 문화적 중요도(CI: Cultural Importance), 상대적 인용빈도(RFC: Relative Frequency of Citations), 상대적 중요도(RI: Relative Importance) 및 문화적 가치(CV: Cultural Value)를 산출하여 우리나라에서 중요한 민속식물을 정량적으로 확인, 비교하였고 각 분류군별 지수도 제시하였다.

As archivists are professional who is responsible for professional works related in archives, they are required to perform expanded roles including traditional roles in changed environment surrounding archives. To solve those requirements, reeducation program can be essential for improving archivists expertise. However, as compared with education quality and programs for professional improvement required to archivists, reeducation program currently offered in National Archives of Korea is inadequate to deal with performing the extended roles required to archivists. This study analyzed the current situation and problem of reeducation program currently offered in National Archives of Korea, as compared to domestic and foreign reeducation programs, and surveyed archivists' opinion about requirements to perform their extended roles in practice. Based on the results, this study improved a reeducation program in National Archives in Korea.

조혈모세포이식술(또는 HSCT)을 받은 환자에게는 이식관련 부작용의 예방 또는 치료를 위해 면역억제 약물이 투여되는데, 그 중 하나인 cyclosporine은 therapeutic index가 작고 다양한 요인에 의해 혈중농도가 변화되므로 사용시에는 세심한 관찰과 조절이 필요하다. 특히 HSCT 환자에서 발생하는 호중구 감소성 발열(또는 NPF)의 치료목적으로 투여하는 항생제에 의하여 cyclosporine의 혈중농도가 변화될 수 있고, 또 임상적 경과에 따라 항생제 처방이 중도에 변경되는 경우도 빈번하지만, 실제로 항생제 처방의 중간변경에 의한 cyclosporine의 혈중농도 변화양상을 연구한 결과는 많지 않다. 이에, 과거 2년 동안 한 상급종합병원에서 HSCT후 cyclosporine을 투여 받았던 환자 중에서 통상적인 NPF 치료용 항생제인 ciprofloxacin을 투여하다가 치료성과를 높이기 위하여 cefepime으로 대체 투여했던 환자들의 의무기록을 후향적으로 분석하였다. 1차 선택약인 ciprofloxacin에서 항생제를 변경했을 때 cyclosporine의 혈중농도가 유의성 있게 증가했는데, 이는 ciprofloxacin 보다 cefepime이 간에서 cyclosporine을 분해시키는 효소생성을 억제시켰기 때문일 것으로 예측되며, HSCT 환자에서 NPF 치료용 항생제를 ciprofloxacin에서 cefepime으로 변경 시에는 병용중인 cyclosporine 유지용량을 약 13% 감량하는 것이 cyclosporine의 효과는 유지하면서 부작용의 발생위험을 감소시키는 데 유용한 방안이 될 것으로 사료된다.

The purpose of this research was, first, to classify work-life satisfaction among married wage workers aged 20-59 years into several distinct types based on two dimensions of work and life, using data from the 20th(2017) wave of the Korean Labor & Income Panel Study. Second, the study aimed to assess the differences in socio-demographic characteristics (sex, age, educational level, average monthly income), and workplace-related variables (weekly working hours, full-time employment, job stability, business type, family-friendly leave policies) by work-life satisfaction type. Accordingly, four types of work-life satisfaction were identified: work-life satisfaction, work-life dissatisfaction, work satisfaction, and life satisfaction. There was a significant difference in the type of work-life satisfaction among married waged workers based on sex, age, educational level, and average monthly income. Additionally, there was a significant difference in the type of work-life satisfaction for all workplace-related variables, namely, weekly working hours, full-time employment, job stability, business type, and family-friendly leave policies. In particular, proportionally higher values of work-life satisfaction were evident among the workers in companies with family-friendly leave policies such as paid leave, menstrual leave, maternity leave, childcare leave, and family events leave, whereas there was a high rate of work-life dissatisfaction among the workers in companies without family-friendly leave policies.

This study analysis fundamental properties of high-strength concrete corresponding to W/B ratio for suggested table of high strength concrete, mixed with premixed cement. As a result of this study, the amount of using air entraining and high-range water reducing agent for intended slump flow and air content decreased as W/B increased, and the setting time corresponding to the W/B ratio delayed as W/B ratio increased except 20% W/B ratio. The compressive strength according to W/B ratio decreased as W/B ratio increased, and there was no great deferent as the intended slump flow. Also it could possible to use this study at work as the correlation coefficient is high enough as 0.9646 substituting B/W and compressive strength for the regression formula.
