텍스트 마이닝 기법을 활용한 기후변화관련 식품분야 논문초록 분석
배규용,박주현,김정선,이영섭,Bae, Kyu Yong,Park, Ju-Hyun,Kim, Jeong Seon,Lee, Yung-Seop 한국데이터정보과학회 2013 한국데이터정보과학회지 Vol.24 No.6
빅 데이터 분석기법 중 비정형데이터 분석기법인 텍스트 마이닝 기법을 이용하여 기후변화 관련 식품분야 논문 초록에서 용어들의 출현빈도를 분석하였다. 이를 위하여 용어-문헌 행렬을 만들고, 용어들간의 비유사성 측도를 바탕으로 계층적 군집분석기법을 적용하여 문서들을 군집화하였다. 군집화된 문서들간의 상호 연관성과 군집별로 특정용어의 빈도를 파악하여 문서군집을 특정주제별로 분류하였다. 이러한 연구를 통하여 식품분야의 기후변화 관련 논문들의 추세와 관심주제어를 파악할 수 있었으며, 향후 기후변화 적응 및 대응 체계 로드맵 작성 시 연구 개발 기초 자료로 활용할 수 있을 것이다. Research articles in food related to climate change were analyzed by implementing a text-mining algorithm, which is one of nonstructural data analysis tools in big data analysis with a focus on frequencies of terms appearing in the abstracts. As a first step, a term-document matrix was established, followed by implementing a hierarchical clustering algorithm based on dissimilarities among the selected terms and expertise in the field to classify the documents under consideration into a few labeled groups. Through this research, we were able to find out important topics appearing in the field of food related to climate change and their trends over past years. It is expected that the results of the article can be utilized for future research to make systematic responses and adaptation to climate change.

In recent years applications of artifical ventilation after surgery have broadened with improved diagnostic and therapeutic tools and better understanding of pathophysiology of adult respiratory distress syndrome(ARDS). This report includes 15 cases of ARDS complicated following intraabdominal surgery, whic hcomprise 2. 2% of 681 cases performed in the department of general surgery of this hospital during the period of 6 months from October 1975 through March 1976. The results were as follows: 1) Male to female ratio was 11: 4. 2) Average was 51.4 years with mortality rate of 53. 5% without sexual difference. 3) More frequent incidence and higher mortality rate of ARDS occurred in patients with total serum protein less than 6.0gm% and serum albumin less than 2.9gm%. 4) Average duration of artificial ventilation was 35. 6 hours in the survived group and 44. 5 hours in the expired group. 5) Preoperative ventilatory values(minute volume, frequency and vital capacity) and arterial blood gases revealed no differences between the survived and the expired groups. 6) Six of 15 cases of ARDS were transfused with more than 4,000ml of ACD bank blood. 7) Potential date of onset of ARDS were not predictable.

폴리에치렌 글리콜 - 400 에 의한 목재의 칫수안정화
조남석,조재명,배규용 한국목재공학회 1975 목재공학 Vol.3 No.1
How to stabilize wood against shrinking and swelling in variable atmospheric moisture conditions is important to the wood-using industry and a challenge to research. Polyethylene glycol stabilize wood by bulking the fiber. PEG also serve as a chemical seasoning agent, suppress decay in high concentrations, and have slight effect on physical properties, gluing or finishing. The study designed to determine the effect of PEG-400 on the dimensional stabilization of local hardwoods for wood carvings that could supply a greatly expanding tourist trade and making curved furniture parts, lamp stands and other decorative objects, and possible gunstock. The species examined were 6 species, Seo-Namoo (Carpinus laxiflora), Cheungcheung-Namoo (Cornus controversa), Garosae-Namoo (Acer mono), Karae-Namoo (Juglans mandshurica), Jolcham-Namoo (Quercusserrata) and Sanbud-Namoo (Prunus sargentii), used as block of 5cm thick radially to the grain, 7cm wide tangentially, and 70cm long parallel to the wood grain. All these test piecies were conditioned above the fiber saturation point before impregnation. The stabilization effects were determined for PEG-400 treated woods in a 50 percent solution for 20 days. The following conclusions were obtained. PEG retentions increased with treating time. It was more effective to treat at 60℃ than at room temperature. In degree of PEG-400 impregnation on species, Cheungcheung-Namoo havinglow specific gravity had the highest retentions, 68.77% but the lowest, 56.33% was shown in Jolcham-Namoo with high specific gravity. Specific gravity of treated wood increased considerably with effectiveness of polymer loading. The increases in sped e gravity were 5.36 to 13.16 percent. The highest was Jolcham-Namoo, the lowest Karae-Namoo. On the dimensional stability, a 40 percent of effectiveness of polymer loading was just as effective as 60 percent in reduction in water absorptivity (RWA), antishrinkage efficiency (ASE) and antiswelling efficiency (AE), and from over 60 percent they increased more rapidly. Also species response varied considerably. ASE was 30.12 to 69. 97 percent tangentially and 27.86 to 56.37 percent radially, AE 34.06 to 73.76 percent tangentially and 30.11 to 70.12 percent radially, and RWA 42.31 to 65.32 percent. No differences in volume swelling among the 6 species were observed. Its values were ranged from 14.98 to 19.55 percent and also increased with PEG retentions. On the mechanical properties, the strengths very much decreased with PEG-400 loadings as shown in Figure 12; that were 11.41 to 22.90 percent in compression, 21.61 to 34.35 percent in bending and 22.83 to 36.83 percent in tensile strength. PEG retention in cell wall was less than 1 percent and the most of PEG were immersed in cell lumen. Except for Korae-Namoo, effectivenesses of polymer loading were as much high as 61.58 to 75. 02 percent. This is believed to be due to the effect o PEG-400 on excellant dimensional stability of treated woods.

It was obtained following results on changes of various constitutions in the blood of eleven pationt who had massive blood transfusion ( average 14. 6 pints of ACD stored blood) in Seoul Natioeal Ueivety Hespital. I. It revealed no definite change of hemoglobin and hematocrit value in two days after masave blood transfusion. 2. Counts in platelets in two days after transfusion decreased from normal value to about I00, 000/mm3 except one case who had transfused 35 pints of bleod. 3. No hypearpotasaemia obser ved in two days after massive transfusion with usage of the blood warmer. 4. Temporary increeaee of blood glueose revealed with tendency of deerease to normal values in two days after maeeive transfusion. 5. The pattern of respiratory alkalosis revealed in two days after massive blood transfusion. It implies that the alkalizing agent is not recommended to inject routinely for the transfused patients without checking acid-base status. 6. It is highly recommended to check body temperature, hematocrit, hemoglobin, platelets and values in arterial blood gas and apply the blood warmer for cares in massive transfused patients.
