본 연구의 목적은 전(前)게임기의 사회문화적 맥락은 어떠했으며, 그것이 게임의 정체성 형성에 어떻게 작용했는지를 고찰하는 것이다. 게임은 그 존재양식이 처음부터 고정되어 일관된 정체성을 지니고 발전한 것이 아니다. 다양한 담론과 기술, 사회적인 요소와의 접합 과정에서 역사적으로 배태된 결과물이라 할 수 있다. 1960년대 회전당구를 비롯한 기계오락 장치는 도시 대중의 유흥을 위해 활발히 소비되었으며, 본격적으로 게임이 등장하기 전에 사행성 문제 및 병리적 현상으로서 사회적 긴장 관계를 형성하였다. 이들 기계오락은 1970년대 이후 전자오락으로 이어지는 흔적이 나타나는 등 현재 디지털 게임 문화의 흐름과 맞닿아 있다.

The purpose of this study was to investigate the satisfaction on the Gwangju Kimchi Festival. The results of this study were as follows: In terms of satisfaction on 'pre event publicity of the Festival', the satisfaction of '03 was high. It was founded that Publicity through TV was successful. The visitors' satisfaction on understanding regional cultures was low. It was consecutively low for three years. There should be strategic development plans to increase satisfaction about understanding regional cultures. It was found that TV was the major pre event information resource for the residents. Also word of mouth was the most important pre event information resource for domestic tourists. The satisfaction on access to festival was increased consecutively. Providing free shuttle buses to the festival place and placing festival placard influenced positively. There should be expansion of service facilities. There should be more strengthening of festival information services and guiding facilities. More professional interpretation systems and interpretation education are necessary. Visitors satisfied about festival products and quality of the products. Visitors satisfied with festival events programs and hands on experience based programs including making diverse Kimchi.

This study was conducted to examine the effect of salt concentration in soybean sauce (ganjang) on pre-rigor ground Hanwoo (Korean native cattle) muscle. Although adding soybean sauce reduced pH of pre-rigor Hanwoo muscle, it improved the water holding capacity (WHC), cooking loss, total protein solubility, myofibrillar fragmentation index (MFI), 2-thiobar-bituric acid (TBA) values, and textural properties by increasing salt concentration in the soybean sauce. In particular, adding soybean sauce inhibited lipid oxidation despite increasing salt concentration. An increased salt concentration in the soybean sauce in pre-rigor Hanwoo muscle tended to make the meat have lower lightness and higher redness and yellowness values. Although soybean sauce had a significantly lower pre-rigor salting effect than sodium chloride in terms of cooking loss and total protein solubility (p<0.05), soybean sauce improved myofibrillar fragmentation and lipid oxidation when compared with sodium chloride. Furthermore, no significant differences in textural properties were observed between adding soybean sauce and sodium chloride at the same salt concentrations. Therefore, soybean sauce can be a functional curing material for pre-rigor muscle.

To establish a pre-plating method of chicken satellite cells with high purity, pre-plating was performed under culture conditions of 37℃ and 41℃, and the pre-plating time was set from a total of 3 hours to 6 hours in consideration of the cell attachment time. The purity of the cells was confirmed by staining paired box protein 7 (Pax7) after proliferation, and Pax7 expression was the highest in culture flasks shaken for 2 hours after incubation at 41℃ for 2 hours to prevent the attachment of satellite cells (p<0.05). Also, when pre-plating and proliferation were performed at 37℃ and 41℃, the Pax7 expression rate was higher at 41℃. The differentiation capabilities of the three groups (T3, T6, and T7) with high Pax7 expression were compared and the fusion index (%) and myotube formation area (%) determined by myosin heavy chain (MHC) staining was calculated. The T6 and T7 groups, which were cultured at 41℃, showed significantly higher values than the T3 group (p<0.05). There was no significant difference in the expression of Pax7 and MHC between the T6 and T7 groups (p>0.05). These results suggest that pre-plating at 41℃ for a total of 4 hours was the most efficient in terms of cost and time for purifying chicken satellite cells for cultured meat.

이 연구에서는 과학 체험 프로그램의 운영이 예비교사의 과학적 소양에 미치는 영향을 과학문화소양과 핵심역량을 중심으로 알아보았다. K대학교 255명의 예비교사가 참여하였으며, 과학문화소양은 단일집단 사전-사후검사 설계로 대응표본 t-검정을 통해 프로그램의 효과를 알아보았다. 핵심역량 성장 인식은 사후검사만 실시하였으며, ANOVA로 역량별 성장 인식의 차이를 비교하였다. 연구 결과, 과학 문화소양에서 예비교사의 과학문화소양은 사전검사에 비해 사후검사 평균이 더 높았으며, 이 차이는 통계적으로 유의미하였다(p<.05). 핵심역량의 성장 인식 분석 결과, 과학적 의사소통 능력에서 70.6%의 예비교사가 성장을 보고하였으며, LSD로 사후검증 결과 다른 핵심역량에 비해 통계적으로 유의미하게 높은 빈도를 보였다(p<.05). 이를 통해 예비교사의 과학적 소양 함양을 위한 방안으로 과학 체험 프로그램의 교육적 가치를 확인할 수 있었다.

There are many of anaerobic culture methods and equipments for isolation and cultivation of anaerabic bacteria, but most of these methods are used without pre-reduced media. Gas-jet method is a recommend. able method for the culture of anaerobes, resently developed. Bacteriological studies were experimented of liver abscess of cattle by the use of gas. jet method. The results were summarised as follows; 1. Gas-jet method for anaerobic culture are expedient for the making of pre-reduced media, maintaining of oxygen free condition in the culture tube, picking of bacteria from colony and colony counting etc. 2. A 121 strains of facultative anaerobic and anaerobic bacteria were isolated from liver abscess of 27 head of cattle, and the isolated anaerobic bacteria were as follows. Peptostreptococcus spp. 7 strains Acid aminococcus fermentans 1 Veillonella spp. 1 Bacterioides spp. 6 Bifidobacterium spp. 4 Arachinia propionica 2 Lactobacillus spp. 4 Propionibacterium acnes 1 3. Liver abscess were infected with many of bacteria, about $10^3-10^9$ numbers per gram of abcessed tissue. Almost of abscess were mixed infection of various bacterial species rather than simple species.

Background: Patients with ventilator-associated pneumonia (VAP) in intensive care unit (ICU) have a high mortality rate. The routine surveillance cultures obtained previously or an ATS guideline for hospital-acquired pneumonia was used in selecting initial antimicrobials. The object of this study was to compare the respiratory samples before VAP and bronchoalveolar lavage (BAL) culture. Methods: 54 patients underwent fiberoptic bronchoscopy to obtain BAL samples. We reviewed microbiologic specimen results of prior respiratory specimens (pre-VAP) and BAL. Results: Among 51 patients with 54 VAP episodes, 52 microorganisms of pre-VAP and 56 BAL samples were isolated. Pre-VAP included 21.2% of MRSA, and 32.6% of multidrug resistant-Acinetobacter baumannii (MDR-AB). BAL samples comprised 25.0% of MRSA, 26.7% of MDR-AB, 14.3% of Stenotrophomonas maltophilia and 3.6% of Klebsiella pneumonia in order. In pre-VAP samples compared to BAL samples, only 35.2% were identical. In BAL samples compared to pre-VAP samples obtained in 5 days before the onset of VAP, only 43.6% were identical. However, among BAL samples compared to pre-VAP samples obtained after more than 5 days, 13.3% were identical (p=0.037). Conclusion: Based on these data, pre-VAP samples obtained prior to 5 day onset of VAP may help to predict the causative microorganisms and to select appropriate initial antimicrobials.

The purpose of this study was to extract information of lower body type's classification on pre-school children. To this end, 325 younger children living in the capital area and aged from 4 to 6 were sampled to be subject to the measurement of their somatotypes. The results are as follows. 1. The changes in the physical types of pre-school children, as they growing older, show the following tow peculiarities, first, in terms of vertical change, the height grows so rapidly that the proportion of the lower part of the body gets longer. And second, in terms of horizontal change, their growth is more distinctive in the width and the girth than in the thickness, which transforms their body into more or loss a dumpy form. 2. The analysis of the lower body of pre-school children allows us to distinguish two types of group. The first type has a smaller body, short in every part of body, which represents the body of four year-old children. On the contrary, the second type show much bigger body, especially the lower part of the body having a longer proportion, and it represents the body of six year-old children. the physical type and the gender have no relation, which means that we cna fidn both male and female children uniformly in both types.
