This paper described a collaborative exercise intended to see what kinds of short tandem repeat (STR) loci are used in different DNA typing laboratories in Korea and to compare their results for the demonstration whether uniformity of DNA profiling results from different laboratory could be achieved in Korea Laboratories were asked to test five tissue DNAs using methods routinely used in each laboratory and to report the results to the coordinating laboratory. The exercise demonstrated that each laboratory was using different STR loci for the typing with different STR numbers,2 VNTRS,36 STRs and amelogenin in total, and the direct comparison of the results from all the laboratory for the 18 loci could not be done as only one laboratory submitted typing results. Among 21 loci for which several laboratories submitted typing results, results for 14 loci were the same and results for the other 7 loci were different depending on the participating laboratory. D1S80, F13A01, D16S539, D21S11, D18S51, D3S1744 were the loci with different typing results. Even in the cases where commercial kits were used, the results were not the same depending on the machines used, that is the capillary electrophoresis or the gel based electrophoresis. The reason for the different results, points about the standardization of the methods arid the profiling data were described.

이상엽,김윤진,김형회,손한철,전태용,심문섭 대한비만학회 2002 The Korean journal of obesity Vol.11 No.2

연구배경 : 최근 식욕조절인자로 관심이 집중되고 있는 그렐린(ghrelin)은 식사 전후로 독한 일중변동을 보인다. 하지만, 지금까지는 실험적으로 일정한 열량의 표준 음식을 일정한 식사시간에 공급한 이후 그렐린의 농도 변화를 관찰하였다. 저자 등은 평소 아침 식사시간이 각기 다른 사람들에서 아침 식사 전후의 혈장 그렐린 농도 변화를 관찰하여 향후 외래 환경에서도 그렐린 관련 연구가 가능하도록 기초 자료를 제공하고자 하였다. 방법 : 연구에 대한 설명을 듣고 동의한 23.4 ~ 35.5세 사이의 비교적 건강한 동양인 남자 4명을 대상으로 하였다. 신체 계측을 한 후 이중 에너지 방사선 측정법 (Lunar prodigy, GE medical systems, Waukesha, Wisconsis, USA, 이하 DEXA)으로 체지방을 측정하였다. 연구 대상자 모두 평소 아침 식사시간이 일정하였지만 연구 시작 2주전부터 아침 식사시간을 엄격히 고정하도록 하였다. 스트레스가 없는 상태에서 아침 식사를 하지 않는 지원자는 오전 6시 30분부터, 나머지는 아침식사 시간 1시간 전부터 1시간 간격으로 점심 식사 전인 오전 11시 30분까지 채혈하였다. 각각의 검체로 부터 혈장 그렐린은 상업적인 방사선면역측정법 (Phoenix Pharmaceuticals, Inc., Belmont, CA)으로 측정되었다. 랩틴은 Ⅰ-125 표지 랩틴을 이용한 이중항체 방사선면역측정법으로, 혈장 인슐린은 항체 부착관을 이용한 방사선면역측정법으로, 혈당은 포도당산화 효소법에 의해 Synchron LX 20 (Beckman Coulter, Inc, Fullerton, USA)으로 측정하였다. 결과 : 연구 대상자의 체질량지수는 22.9 ~ 27.1 kg/㎡이었고, 허리둘레는 80.3 ~ 93.3 cm이었다. DEXA로 측정한 결과 전체 체지방과 체부지방 비율은 각각 27.1 ~ 31.8%와 32.7 ~ 32.4%이었다. 아침 식사를 하지 않는 자를 제외한 나머지 연구 대상자의 아침 식사 직전의 식후 2시간의 혈장 그렐린 농도는 각각 113.0 ~ 800.0 pg/mL, 78.3 ~ 553.0 pg/mL이었고 랩틴 농도는 각각 4.9 ~ 5.1 ng/mL, 4.4 ~ 4.7 ng/mL 이었다. 혈장 그렐린 랩틴 농도는 아침 식사 직전에 비해 식사 2시간 후 각각 7.2 ~ 30.9%와 7.8 ~ 10.2%감소되었다. 아침식사를 하지 않는 대상자의 경우 인슐린과 혈당치가 변화가 없음에도 불구하고 혈장 그렐린 농도는 오전 7시 30분에 가장 낮았다. 그 외 연구 대상자에서는 각기 다른 시간이더라도 아침 식사 2시간 후의 혈장 그렐린 농도가 가장 낮았다. 결론 : 평소 아침 식사시간이 다른 사람들에게서 혈장 그렐린 농도는 각기 다른 아침 식사 2 시간 후에 가장 낮았다. 아침 식사를 하지 않는 경우에는 혈장 그렐린 농도가 오전 7시 30분에 가장 낮았다. Background : Recently, the particular interest is on ghrelin, the dietary control factor among many scientists and it a toxic diurnal variations has been demonstrated before and after meal. However, the experimental approach has been only to see the changes in the concentration of ghrelin after intake of meals standardized with fixed calories at scheduled meal hours. the authors of this particular experiment have tried to observe and record the changes in concentrations of plasma ghrelin of persons with different breakfast hours. This might help in providing a basis for further possible studies in outpatient setting. Method : A group of four relatively healthy males whose ages between 23.4 and 35.5 with prior agreements were selected for this study. After body measurements, body lipid status was measured based on Lunar prodigy (GE medical systems, Waukesha, Wisconsin, USA) which is also referred to as DEXA. All of the selected persons had somewhat fixed breakfast time; however, they were asked to strictly keep their breakfast time fixed and steady starting two weeks before the beginning of experiment. The bloods of those who skip their breakfast without any particular stress were sampled at 6:30 AM, whereas the rest had different schedule, whose bloods were sampled every hour starting 1 hour before the first meal of the day till just before lunch (11:30 Am). From each blood sample, the level of plasma ghrelin was measured using the commercial radioimmune assay (Phoenix Pharmaceuticals, Inc., Belmont, CA). Leptin was measured with double antibody radioimmune assay using Ⅰ-125 labelled leptin, plasma insulin with radioimmune assay using antibody attachment tube, and blood sugar with Synchron LX20 (Beckman Coulter, Inc, Fullerton, USA) using glucosylation enzyme method. Result : The body mass index of the volunteers was 22.9 ~ 27.1 kg/㎡, with 80.3 ~ 93.3 cm waist circumference. Based on measurements by DEXA, the rates of total body lipid and trunk lipid were each 27.1 ~ 31.8% and 32.7 ~ 32.4%, respectively. The concentrations of plasma ghrelin of those who consume their breakfast before and 2 hour after their breakfast are 113.0 ~ 800.0 pg/mL and 78.3 ~ 553.0 pg/mL. The concentrations of leptin are 4.9 ~ 5.1 ng/mL and 4.4 ~ 4.7 ng/mL. Compared to the concentration of plasma ghrelin and of leptin recorded just before breakfast, it showed 7.2 ~ 30.9% and 7.8 ~ 10.2% decrease, respectively, 2 hours after breakfast. For those who skip their breakfast, the plasma concentration of ghrelin was recorded the lowest at 7:30 AM, even though there was no change in insulin and blood sugar. The rest of the subjects had their lowest plasma ghrelin concentration at 2 hours after breakfast, despite their different meal schedule. Conclusion : The persons with different breakfast hours had their lowest plasma concentration of ghrelin at 2 hours after breakfast. In contrast, the persons who skip their breakfast had their lowest concentration at 7: 30 AM.

The most remarkable characteristics of "jeongjae" (palace dancing and singing) created in the early Chosun dynasty is that it was the means of justifying the foundation of a new dynasty accepting and replacing rather than destroying, Goryeo. As mentioned in the introduction, "dangak" (China-originated music) and "hyangak" (traditional music) had different kinds of jeongjae in the Goryo era, That is, in the former, a bamboo-instrument musician called to the music of dangak, while the words of Chinese characters were sung, in the latter, there was no calling, while the lyrics of Korean alphabets were sung to the music of hyangak. However, among the hyangak jeongjae made in the Chosun age, Chinese lyrics were sung and both hyangak and dangak were played in Botaepyeong and Jeongdaeeop, There was musician calling in Bongnaeeui, Also, dangak was performed in Hyangbal. and Hakmu, Therefore, in the early Chosun dynasty, jeongjae was not clearly differentiated between hyangak arid dangak. Key Words: Creation purposes, Justness of dynasty foundation, Praisal of historical achievement, Toadyism, Exorcist ritual, Reception.

We had investigated combustion properties of rice bran dusts. Decomposition of rice bran dusts with temperature were investigated using DSC and the weight loss according to temperature using TGA in order to find the thermal hazard of rice bran dusts, and the properties of dust explosion in variation of their dust with the same particle size. Using Hartman's dust explosion apparatus which estimate dust explosion by electric ignition after making dust disperse by compressed air, dust explosion experiments have been conducted by varying concentration and size of rice bran dust. According to the results for thermodynamic stability of rice bran dust, there are little change of initiation temperature of heat generation and heating value for used particle size. But initiation temperature of heat generation decreased with high heating rate whereas decomposition heat increased with particle size. Average maximum explosion pressure was 10kgf/㎠ for 60/70 mesh and 1.5mg/㎤ dust concentration.

This study aims to investigate the concentration of formaldehyde, which is one of the most well-known VOCs(Volatile Organic Compounds), and analyze the characteristic of its concentration in newly-constructed apartment houses. The field measurement was conducted in different five apartment house complexes located in Seoul and Kyonggi province. Indoor concentration of formaldehyde showed between 0.018ppm and 0.607ppm. The average concentration was 0.150ppm and above the foreign standards. It result from the new construction. Also, the higher measurement position and the bigger measurement extent, the greater concentration of formaldehyde. And it was treated by the statistic program to examine the objective relations among the concentration of formaldehyd, measurement factors and basic thermo-environment elements. As a result, the temperature, the relative humidity and the measurement position had a validly effect on the concentration of formaldehyde and the temperature extremely influenced it.

애매성 해소를 위한 확률적 한국어 구문 분석기의 설계 및 구현

이상윤,김한우 漢陽大學校 工學技術硏究所 1997 工學技術論文集 Vol.6 No.1

본 논문에서는 한국어를 구문 분석할 때 발생하는 문장 구조의 애매성을 해소하기 위한 확률적 한국어 구문 분석기틀 제안한다. 일반적인 자연 언어 처리는 형태소 분석, 구문 분석, 의미 분석 과정을 거치게 되는데, 각각의 단계에서 애매성이 발생한다. 형태소 분석 단계에서의 애매성을 해소하기 위해서는 통계 정보를 이용한 태깅 방법이 많이 연구가 되고 있다. 그러나, 태깅을 통하여 형태소 분석의 애매성을 전부 해소했더라도 구문 분석시 문법이 가지고 있는 애매성으로 인하여 발생하는 문장 구조의 애매성은 피할 수 없다. 이를 의미 분석 단계에서 전부 해결하려면 의미 분석기의 부담이 가중되고 그만큼 시스템의 성능도 떨어지게 된다. 본 논문에서는 이러한 구문 분석에서의 애매성을 해소하기 위해 구문 태그와 문법 형태소 태그를 혼합한 확률 모델을 제안하고 그 확률모델에 대한 성능을 실험 결과를 통하여 제시한다. This paper proposes a probabilistic Korean syntactic analyzer to solve ambiguity of a sentence structure. Natural language processing is generally processed through morphological analysis, syntactic analysis, and semantic analysis, and at each step ambiguity is generated. The tagging method which uses stochastic information has been studied to solve morphemic ambiguity. Although morphemic ambiguity can be solved through the tagging, syntactic ambiguity which is generated by grammar cannot be avoid of. If we try to solve this problem by semantic analyzer, it imposes more burden on the semantic analyzer and the system's efficiency is decreased. In this paper the probabilistic model which uses both with syntactic tag and morphemic tag is proposed and it's efficiency is demonstrated through experiments.
