        The research aimed to provide accurate and basic data comparing different perceptions of head family’s food and food for religious ceremonies depending on age with the goal of sustaining traditional Korean food in the future. The gender distribution of the participants was 274 Males (42.5%) and 370 Females (57.5%). Age distribution was 211 participants (32.7%) in their 20s, 215 participants (33.3%) in their 30 to 40s, and 220 participants (34%) in their 50 to 60s. The older generation appeared to beaware of the definition of head family or 'The eldest’s house of head family’ as well as the concept of one’s family five generations ago with more reductive and emphasis than imaginary concept of head family of the younger generation. The image of the head family was perceived as ‘head family’s food’ in younger generations and as ‘eldest son’ in older generations. Family role and meaning most often manifested as ‘succession of tradition’ and ‘cultural symbols’ in younger generations, respectively, whereas older generations responded ‘hallmark of the head family’. Family ancestral rites and head family’s food had positive effects on awareness of head family’s food. Moreover, those with experience in practicing family ancestral rites responded that head family’s food should be more popular. People who viewed family’s food more positively were more open with the idea thathead family’s food could go mainstream. In conclusion, positive perception of head family’s food and traditional pride are crucial environmental factors in public support of popularizing head family's food to the public.

        This study investigated the perception, consumer pattern and satisfaction of the ginseng products of 600 people in the Seoul area surveyed from Feb. 1 to 28, 2011. The perception and satisfaction tests were performed using a 5-point scale (1=disagree (dissatisfy) very much, 5=agree (satisfy) very much. People perceived ginseng to have refreshment (3.86), immuno-modulation (3.78), anticancer (3.51), and antiaging (3.41) properties. People in their 20s (4.02) scored high on refreshment compared to people in their 60s and over (3.73). Most people (79.8%) consume ginseng products and prefer red ginseng (74.3%). More people in their 40s (54.1%) and 50s (48.2%) consume ginseng products for refreshment than people in their 20s (38.7%), 30s (41.5%) or 60s and over (40.0%). However, more people in their 50s (36.1%) and 60s and over (43.6%) consume ginseng products for disease prevention than people in their 20s (8.6%). Most people (66.4%) take ginseng all year round. People in their 20s (2.70) showed a smaller satisfaction score of the taste of ginseng products than those in their 30s (3.21), 40s (3.23), 50s (3.26) and 60s and over (3.38).

        The present study compared the developmental potential, telomerase activity and transcript levels of X-linked genes (ANT3, HPRT, MeCP2, RPS4X, XIAP, XIST and ZFX) in the bovine somatic cell nuclear transfer (SCNT) embryos derived from different age and cell cycle of female donor nucleus. In experiment 1, the fusion rate, cleavage rate to 2-cell stage, developmental rate to blastocyst stage, and the mean number of total and ICM cells was slightly increased in embryos cloned with fetal fibroblasts compared to those with adult fibroblasts, but there was no significantly (p<0.05) differences. Telomerase activity was also similar in blastocysts cloned with fetal and adult fibroblasts. Up-regulated RPS4X and down-regulated MeCP2, XIAP, and XIST transcript level were observed in blastocysts cloned with adult fibroblasts, compared to those with fetal fibroblasts. In experiment 2, the fusion rate, cleavage rate to 2-cell stage, developmental rate to blastocyst stage, and the mean number of total and ICM cells was significantly (p<0.05) increased in embryos cloned with fetal fibroblasts at early G1 phase of the cell cycle, compared to those of fetal fibroblasts at late G1 phase. DNMT1 transcript was observed to significantly (p<0.05) increased in the fetal fibroblasts at 3 hrs after trypsin treatment of confluent culture. Further, level of telomerase activity and transcribed X-linked genes was also significantly (p<0.05) higher in the early G1 SCNT blastocysts than those of late G1. The results imply that fetal fibroblasts at early G1 phase induces the enhanced developmental potential and up-regulated telomerase activity and X-linked gene, but aberrant transcript pattern of X-linked genes may be displayed in the SCNT embryos.

        Only limited information is available on the measured exposure levels of residents according to the construction age of apartments. As such, present study was conducted to measure and to compare the bedroom, living-room, and outdoor air levels of MTBE and benzene, toluene, ethyl benzene and m,p-xylene(BTEX) in both newer and older apartments. For both newer and older apartments, all the compounds except for MTBE showed significantly higher levels in bedrooms or living-rooms as compared to the outdoor concentrations. The ratio of bedroom or living-room median concentration to outdoor concentration was close to 1 for MTBE, whereas it was larger than 1 for other target compounds. It was also found that the bedroom and living-room appeared to have similar indoor sources and sinks for BTEX, but not for MTBE. The median concentration ratios of the newer apartments to the older apartments ranged from 1.63 to 1.81, depending upon the compounds. In contrast, the MTBE concentrations did not differ significantly between the newer and older apartments, thereby suggesting that although newer buildings could emit more VOCs, this is not applicable to all VOCs. Conclusively, the findings of present study should be considered, when designing exposure studies associated with VOC emissions in buildings and/or managing indoor air quality according to construction age of buildings.

        붉나무의 수령 및 환경요인에 의한 오배자 생성 영향, 오배자의 생성과정과 오배자면충의 밀도변화, 붉나무 잎의 위치에 따른 오배자 형성부위, 그리고 오배자면충을 인공적으로 접종하여 오배자의 생성관계를 조사한 결과를 요약하면 다음과 같다. 붉나무의 수령에 따른 오배자의 생성은 3개 지역 공히 평균 11-15년 경과된 나무에서 가장 많은 오배자 형성율과 개체수를 나타낸 반면, 1-5년 경과된 나무에서 가장 적은 오배자 형성율과 개체수를 보였다. 붉나무 서식방향에 따른 오배자 형성 개체는 동쪽, 남쪽, 북쪽, 서쪽 순으로 많은 수를 나타내었다. 붉나무의 식생과 오배자의 생성관계는 차이를 보이지 않았으며, 도로변에 서식하고 있는 붉나무에서는 오배자 형성을 볼 수 없었던 반면, 계곡에 이끼가 서식한 습한 곳에서는 많은 오배자가 형성되었다. 오배자의 생성과정을 보면 5월 초순경 붉나무잎 뒷면 엽출날개에 기생하면서 8월 초순까지는 적은 혹을 형성하다가 8월 중순에 충영이 급격히 크게 형성되면서 월동을 위해 탈출직전인 9월 하순에 가장 높은 밀도를 나타내었다. 오배자면충 밀도는 오배자 크기에 비례하여 증가현상을 보였다. 붉나무 잎의 위치에 따른 오배자 형성부위는 정소엽을 기준으로 제 2 엽축날개에서 가장 많은 충영이 형성되었으며, 잎의 앞면과 복엽에는 거의 형성되지 않은 반면 엽축날개에 94%가 형성되었다. 자연 환경속에서 오배자를 형성할 수 없는 붉나무의 군락지에서 인공적으로 오배자면충을 접종하였을 경우 오배자를 생산할 수 있었으며, 오배자의 발육과정 중 일부는 발육하지 못하고 소멸되는 것도 있었다.
