Ancient cultural heritage made up of wood and organic fibers have been easily disintegrated or decomposed by various microorganisms like bacteria and fungi. Here, we demonstrate the effectiveness of an atmospheric pressure plasma jet (APPJ) system to sterilize the microorganisms in tangible cultural heritage. We collected several specimens from the surface of ancient documents and wooden artifacts. Finally, two bacteria and two fungi were prepared and sterilized using the APPJ treatment. The APPJ system is beneficial to its simple apparatus, quick operation time, and cost-effectiveness. Bacteria were almost sterilized within only 1 min treatment using 15 % O2 and applied bias voltage of 100 V. In case of the fungi, sterilization rate reached over 83 % but difficult to reach over 90 % even 10 min treatment. According to the plasma diagnostics using optical emission spectroscopy, it was found that the reactive oxygen species such as OH groups are critical for sterilization of microorganisms. Although further efforts should be performed, we believe that efficient sterilization could be realized by the simple, quick, and portable APPJ treatment system.

Secondary accident is common type of accident which occurs in Korean highway tunnels. Fatality rate of secondary accidents in highway tunnels is six time higher than primary accidents. Video type VMS is a new way of providing information to road users which was recently introduced by Korean government to prevent secondary accidents in highway tunnels. In this study we compared changes in driver's behavior when information is provided by Text type and Video Type VMS. In addition to analyze effects of secondary accident reduction, driving behavior was analyzed based on providing advance information by video type VMS at tunnel entrance. Analysis showed that both text type and video type VMS has similar effect on driver behavior. Video type VMS showed positive effect on driver's behavior to prevent secondary accident when information is provided 1km ahead of accident. Considering there results and the short-term memory characteristics of driver, it was determined that information should be provide at about 650m from the entrance of the tunnel. The results of this study are consistent with the requirement that VMS should be installed at least 500m ahead of tunnel and produce more accurate providing information points. 650m is also appropriate interval for providing information in tunnel to cope with an accident ahead.

Over the past 30 years, the business effects of the improvement project at black spot have been decreasing since 2010, with a reduction in the amount of government spending, coupled with proposing a uniform improvement plan. In order to promote more efficient improvement projects, it is necessary to evaluate the efficiency of local governments and improve the business methods of local governments with low efficiency. However, more sophisticated efficiency analysis methods are needed. Because in previous studies have been limited to the analysis of effects before and after the project through the simple before-after analysis. For this purpose, this study analyzed the efficiency of improvement project at black spot by local governments in Gyeonggi-do using DEA to compare and analyze efficiency in various fields. As a result, Goyang, Seongnam, Paju, Hanam and Yangju showed high efficiency local governments. For local governmetns with low efficiency, the improvement projets to improve efficiency were divided into civil engineering work, structure work, pavement work, additional work and transportation work, and the appropriate construction ratios of each local government were analyzed and presented.

목적: 자궁경부세포검사에서 검출된 비정형 샘세포의 진단적 의의와 심각한 병변을 예측할 수 있는 위험인자를 발견하고, 심각한 병변을 진단할 수 있는 검사방법이 무엇인지를 알아보기 위해 비정형 샘세포의 유형 및 조직학적 진단에 따른 인유두종바이러스검사의 결과에 따라 비교하였다. 연구 방법: 2003년 1월부터 2007년 6월까지 전남대학교병원 산부인과에서 시행한 자궁경부 액상 세포진검사에서 비정형 샘세포가 검출되었고, 이 후 조직검사 및 인유두종바이러스 유전자 분류검사 (HPV DNA chip test)를 시행한 88명을 대상으로 하였다. 환자들의 의무기록을 후향적으로 검사하여 진단당시의 연령, 폐경 상태 등에 따른 결과를 비교 분석하였다. 결과: 자궁경부 액상 세포진검사상 비특이적 비정형 샘세포가 60예, 종양성 비정형 샘세포가 28예였다. 비특이적 비정형 샘세포가 검출된 60예 중 정상은 31예, 자궁경부상피내종양 분화도 1 (CIN1)은 3예, CIN 2는 1예, CIN3는 3예, 침윤성 평편상피암 2예, 침윤성 샘상피암 7예, 자궁내막암 12예, 자궁내막증식증 1예였다. 또한 종양성 비정형 샘세포 28예 중 정상은 6예, CIN1은 1예, CIN3은 2예, 침윤성 편평상피암 1예, 샘상피내암 5예, 침윤성 샘상피암 9예, 자궁내막암 4예 등을 나타내었다. 인유두종바이러스검사 결과 정상과 CIN 1에서 6예 (14.6%, 6/41)를 보였고, CIN2와 3에서 5예 (83.4%, 5/6), 침윤성 편평상피암은 2예 (66.7%, 2/3), 샘상피내암은 4예(80%, 4/5), 침윤성 샘상피암은 11예 (69%, 11/16), 자궁내막암에서는 3예 (18.7%, 3/16)에서만 양성을 나타내었고, 자궁내막 증식증 1예에서는 인유두종바이러스가 검출되지 않았다. 자궁경부에 CIN2 이상의 고등급 병변을 갖는 경우 인유두종바이러스검사에 대한 민감도는 73.3%, 특이도는 85.3%, 양성예측도는 78.5%, 음성 예측도는 81.3%의 결과를 얻었다. 자궁내막암으로 진단된 경우는 모두 35세 이상이었으며, 비정상 자궁출혈을 보인 경우가 대부분이었다. 결론: 자궁경부 액상 세포진검사에서 비정형 샘세포를 보이는 경우 고등급 병변을 나타내는 경우가 많고, 특히 샘세포 병변을 나타내는 경우가 많아 질확대경검사하의 조준 생검뿐 아니라 자궁목내 소파술 또는 자궁내막조직검사를 시행하여 샘세포 병변을 찾기 위한 노력이 강화되어야 한다. 인유두종바이러스검사는 고등급 병변에 대한 높은 민감도를 보여주고 있어서 비정형 샘세포를 보인 여성에서 바이러스검사가 양성이지만 조준 생검 등에서 병변이 없을 경우 원추절제술 등 추가검사를 시행해야 될 것으로 판단된다. 비정형 샘세포를 보이며 인유두종바이러스검사가 음성이고 35세 이상이며 비정상 자궁출혈을 호소하는 경우 반드시 자궁내막조직검사가 필요하다고 판단된다. Objective: This study was aimed to identify the diagnostic role of HPV DNA chip test that may predict high grade lesions in gladular cell abnormalities on cervical cytology. Methods: This study was performed in 88 patients, who were reported for atypical glandular cells on liquid-based cytologic test and was done subsequent cervical biopsies in Chonnam National University Hospital, between January 2003 and June 2007. HPV DNA chip test was performed on residual material of previous liquid-based cytologic test. And it was compared with pathologic results. Results: Of the 88 patients with atypical glandular cells, the distribution was as follows: 60 patients were reported as atypical glandular cells, not otherwise specified (AGC, NOS), 28 patients were reported as atypical glandular cells, favor neoplastics (AGC, favor neoplastics). Of the 88 patients with an AGC result, pathologic results were as follows: 47 patients (53.4%) had a clinically significant high grade lesions. Of this high grade lesions, 5 cases of high grade squamous intraepithelial lesion, CIN 2 & CIN 3 (83.4%, 5/6), 2 cases of SCC (66.7%, 2/3), 4 cases of AIS (80.0%, 4/5), and 11 cases of endocervical adenocarcinoma (69%, 11/16) were positive on HPV DNA chip test. The sensitivity of human papilloma virus positivity to predict the presence of high grade lesion in cervix was 73.3%, specificity 85.3%, positive predictive value 78.5%, and negative predictive value 81.3%. There were 16 patients with endometrial cancer. Only 3 patients were HPV DNA chip positive. All of patients with endometrial cancer were over 35 years of age and almost have symptoms of abnormal genital bleeding except one. Conclusion: HPV DNA detection was strongly associated with high grade lesions in women with atypical glandular cells on cervical pap smear. These results suggest that although there is no high grade lesion in patients with HPV positive AGC-NOS at initial work-up, meticulous search like cone biopsy should be done to find high grade lesion. If the women with a diagnosis of AGC on pap smear are over 35 years of age and has abnormal utero-vaginal bleeding, this patients needed to be evaluated with endometrial biopsy.

Consumer demand for Triticale cultivars as a winter forage crop in Korea has been increasing because of its ability for high andstable yield. However, more than 10 years are required to develop new varieties with conventional breeding programs. A speed breedingsystem using long-day photoperiodic treatment has recently been suggested and applied in wheat and barley, but not in the triticale breedingprogram in Korea. To evaluate the availability of the established speed breeding system for triticale breeding programs in Korea, we usednine domestic triticale cultivars to investigate their growth characteristics under a 22 h photoperiod. The average days to heading (DTH) ofthe nine cultivars was 38 days, and Gwangyoung and Minpung showed the most delayed DTH at 42 days. Therefore, all nine triticale cultivarswere able to shorten the growth duration under the tested photoperiod condition. One productive tiller and more than 10 seeds were obtainedfrom each cultivar. The germination percentage was over 82% when the spikes were harvested 20 days after heading, dried, and chilled fora week to break dormancy. These results suggest that in Korea, the rapid generation advancement system with simple long-day photoperiodictreatment can be applied to triticale breeding programs to reduce the breeding time.

소명기,Kwong, D.L 江原大學校 産業技術硏究所 1999 産業技術硏究 Vol.19 No.-

Ultra thin Ta₂O5 gate dielectrics were prepared by RTMOCVD (rapid thermal metal organic chemical vapor deposition) using Ta source TaC12H30O5N and O₂ gaseous mixtures. As a result, Ta₂O5 thin films showed significantly low leakage current compared to SiO₂ of identical thickness, which was due to the stabilization of the interfacial layer by NO (SiOxNy) passivation layer. The conduction of leakage current in Ta₂O5 thin films was described by the hopping mechanism of Poole-Frenkel (PF) type.

An attempt was made to clarify the effect of various uterine contractors on live non pregnant uteri of mature albino rabbits weighing approximately 2.0㎏. Another group of albino rabbits was conditioned with 0.15㎎ per ㎏ of body weight of estradiol for 3 days and observed 24 hours later. Intrauterine pressure as well as duration and frequency of contractions were recorded accurately by the physiography. The blood pressure and respiratory tidal volume were also recorded simultaneously. Group Ⅰ was control. Group Ⅱ was estrogen preconditioned. Contractors were spartein sulfate, ergonovine, methergine, oxytocin and prostaglandin F_(2α). The results obtained were as follows: 1. The intrauterine pressure of the control group was 9.5 ㎜Hg for 45.4 sec with the frequency of 2.51 per minute, while that of the estrogen preconditioned group was 16.7 ㎜Hg for 24 sec with 2.5 contractions per minute. It showed that intrauterine pressure was significantly increased while the duration of contractility was shortened in the estrogen preconditioned group. There was no significant change in the blood pressure or the tidal volume of respiration. 2. The uterine contractility of the control group with spartein sulfate was 15.3 ㎜Hg for 127.2 sec with 3.6 contractions per minute, while that of the estrogen preconditioned group was 17.0 ㎜Hg for 118.3 sec with the frequency of 3.0 per minute. Although it showed that there was no significant change in the uterine contractability, there was slight increase in the blood pressure in the estrogen preconditioned group with pressure of 116 ㎜Hg and 100 ㎜Hg in the control group. 3. The intrauterine pressure of the control group with ergonovine was 12.6 ㎜Hg for 59.0 sec with the frequency of 2.3 per minute, while that of the estrogen preconditioned group was 15.8 ㎜Hg for 43.5 sec with 3.5 contractions per minute. It was, therefore, shown that there was no significant change in the intrauterine pressure, but the duration of contraction in the estrogen preconditioned group was shortened compared with that of the control group. There was 12 ㎜Hg increase in the blood pressure of the control group and there was no change in the estrogen preconditioned group. No significant change in respiration was noted. 4. The uterine contractability of the control group with methergine was 12.2 ㎜Hg for 24 sec with 5.2 contractions per minute, while that of the estrogen preconditioned group was 14.5 ㎜Hg for 40.8 sec with the frequency of 3.5 per minute. Although, there was no significant change in the intrauterine pressure, the duration of contraction in the estrogen preconditioned group was prolonged 17 sec. The blood pressure was the same with 100 ㎜Hg in both groups and there also was no change in respiration. 5. The intrauterine pressure of the control group with oxytocin was 17.0 ㎜Hg for 56.3 sec with the frequency of 2.7 per minute, while that of the estrogen preconditioned group was 22.1 ㎜Hg for 115.6 sec with 2.4 contractions per minute. It was, therefore, shown that the increase of the uterine contractability in the oxytocin group was much higher than with other previously used contractors and the duration of contraction was doubled. There was no significant change in the blood pressure between the control group (108 ㎜Hg) and the estrogen preconditioned group (100 ㎜Hg), and no significant change in respiration was seen. 6. The uterine contractability of the control group with prostaglandin F_(2α) was 18.8 ㎜Hg for 162.7 sec with 1.8 contractions per minute, while that of the estrogen preconditioned group was 20.0 ㎜Hg for 118.9 sec with the frequency of 3.2 per minute. There was no significant change in the uterine contractability in either the control or the estrogen preconditioned group. The blood pressure showed an increase in both the control group (116 ㎜Hg) and the estrogen preconditioned group (128 ㎜Hg), a greater increase in the estrogen preconditioned group with PGF_(2α). The respiratory tidal volume and the frequency of respiration in both groups showed significant increase.
