  • Fruit growth in kiwifruit shows double sigmoid curve, but it does not certainly indicate as years. Therefore, I though the reason to be easy to the effect of water state change in kiwifruit, investigated diurnal change in water status of fruit tissues with an isoipiestic psychrometers against the fruit growth stage of kiwifruit in 1995 and 1996. Diurnal change in the fruit tissue water potential were little, but violent for fruti growth state III in 1996. The potential of two years dropped gradually approach to harvest time. On the other hand, osmotic potential of the tissues indicated to very similar to water potential, dropped rapidly -1.5MPa before dawn, recovered -1 MPa after 3 h on October 14, were -1~-1.7 MPa at the fruit commercial harvest in 1995. It had a tendency to lower in 1996 than in 1995. It was recorded to the minimum air temperature at the first for an autumn in 1995; 13$^{\circ}C$ from the middle night of October 13 to dawn of October 14. Leaves water potential, which is related to water status of xylem, nearly fell below -1 MPa at before dawn from stage II in 1996. However, it fell so low only at commercial in 1995. At the stage II, osmotic potential and ascent of the turgor pressure was high than 1995-fruit. There parameter suggested that three of kiwifruit in 1996 were status of water stress for stage III. The results from this study indicated that difference of fruit growth between 1995-fruit and 1996-fruit was affected by water status of the fruit tissues, which was influenced by weather condition.

  • Current estimation of greenhouse gas (GHG) emissions from livestock agriculture in Korea was based on Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories (1996 IPCC GL) published in 1996 and emission data were published in National Inventory Report. New guideline book, 2006 IPCC Guidelines for National Greenhouse Gas Inventories (2006 IPCC GL), however, was published in 2006. Hence preparation to apply new guideline for the estimation of GHG emission would be necessary. In this study, 1996 IPCC GL and 2006 IPCC GL for livestock agriculture were compared. Estimated GHG emissions based on Tier 1 methods of 1996 IPCC GL and 2006 IPCC GL between 2000 and 2008 were also compared. Estimated GHG emissions based on 2006 IPCC GL were 1.27~1.33 times higher than those based on 1996 IPCC GL. These results were mainly caused by emission factors of each IPCC GL. More researches should be conducted to decrease uncertainties of national GHG inventories.

  • As the result of epidemiological analysis on bovine tuberculosis in Kyonggi province during the last ten years(1987-1996), 1. The annual incidence number of bovine tuberculosis positive farms in Kyonggi province fell down from 81 in 1987 to 14 in 1989. But the incidence is increased since 1990, in 1995 the incidence number was 102 farms of the most incidence. Total number of bovine tuberculosis positive farms were 456 farms(56.7%) in Kyonggi province during the 1987-1996 period. 2. The developmental trends of bovine tuberculosis positive heads was similiar to that of positive farms. Since 1993, the incidence was suddenly increased. Total number of bovine tuberculosis positive heads were 1,015 head(64.3%) in Kyonggi province during the 10 years. 3. Average incidence for rate during the last ten years(1987-1996) was 0.10%. The positive rate was suddenly increased since 1993 and in 1996, the positive rate was 0.23% of the highest incidence. 4. Regional Incidence number of bovine tuberculosis positive heads in Kyonggi province during the last seven years(1990-1996) was the most in Hwasung, Pochon, Pyungtek in order of Incidence and bovine tuberculosis positive density was 1.297% of the highest in Buchon. 5. In 244 farms(82.4%), bovine tuberculosis first occurred during the last seven years (1990-1996) but in farms over second occurrence, the number of bovine tuberculosis positive heads were 520 heads(58.2%).

  • Background : Intensive care units (ICUs) are generally considered epicenters of antibiotic resistance and the principal sources of multi-resistant bacteria outbreaks. The antibiotic resistance in newly opened intensive care unit that has no microbial colonization on and around the devices was investigated. Materials and Methods : The authors analyzed the antibiotic resistance patterns for common hospital acquired-pneumonia pathogens in the ICUs(Staphylococcus aureus, Pseudomonas aeruginosa, Acinetobacter spp.) at the newly opened ICU of Hanyang University Medical Center, Kuri Hospital during 6 years(1995-2000). Results : 1) Regarding Staphylococcus aureus, the resistance rate to methicillin was 15% at 1995, 21% at 1996, 20% at 1997, 23% at 1998, 22% at 1999, 55% at 2000. 2) Regarding Pseudomonas aeruginosa, the resistance rate to $3^{rd}$ cephalosporin was 50% at 1995, 50% at 1996, 78% at 1997, 40% at 1998, 77% at 1999, 39% at 2000. Imipenam was 0% at 1995, 27% at 1996, 65% at 1997, 12% at 1998, 16% at 1999, 12% at 2000. Ciprofloxacin was 0% at 1996, 56% at 1997, 36% at 1998, 57% at 1999, 58% at 2000. Tobramycin was 7% at 1995, 10% at 1996, 67% at 1997, 36% at 1998, 65% at 1999, 12% at 2000. Gentamycin was 14% at 1995, 36% at 1996, 67% at 1997, 36% at 1998, 65% at 1999, 12% at 2000. Amikacin was 14% at 1995, 30% at 1996, 61% at 1997, 16% at 1998, 39% at 1999, 18% at 2000. 3) Regarding Acinetobacter spp., the resistance rate to $3^{rd}$ cephalosporin was 92% at 1996, 89% at 1997, 88% at 1998,84% at 1999, 77% at 2000. Imipenem was 50% at 1996, 48% at 1997, 45% at 1998, 49% at 1999, 50% at 2000. Ciprofloxacin was 0% at 1996, 48% at 1997, 33% at 1998, 27% at 1999, 71% at 2000. Tobramycin was 67% at 1995, 100% at 1996, 89% at 1997, 95% at 1998, 87% at 1999, 77% at 2000. Gentamycin was 67% at 1995, 100% at 1996, 89% at 1997, 95% at 1998, 87% at 1999, 83% at 2000. Amikacin was 33% at 1995, 83% at 1996, 82% at 1997, 88% at 1998, 75% at 1999, 69% at 2000. Conclusion : The S.aureus resistance to methicillin, the Pseudomonas aeruginosa resistance to ciprofloxacin, and the Acinetobacter spp. resistance to ciprofloxacin have rapidly increased during 6 years. There is a need to pay speicial attention when using the the antibiotics for the above pathogens. This data may be useful in antibiotic therapy in newly opened intensive care units.

  • To identify the differences on plant growth and yield of two rice cultivars among direct water-seeding methods broadcasting on flooded paddy surface(BF), drilling on flooded paddy surface(DF), and puddled-soil drill seeding(PD) under markedly different weather condition between 1995 and 1996. The mean air temperature for duration from May to June, early growth stage of rice in 1995 was lower $1{\sim}3^{\circ}C$ than that in normal or 1996. In 1995 the respiratory consumption index during panicle formation stage and early ripening stage was higher than those of in 1996 or normal year. Number of seedling stand among the methods of direct seeding rice appeared slightly higher in order of BF>DF>PD. Properly in Nonganbyeo, the number of seedling stand was much low in 1995 compared with in 1996. The leaf area index and shoot dry weight at early growth stage of rice plant and culm length at mature in 1995 were larger in direct water seeding rice than those of machanical transplanting rice, but in 1996. Faster ripening speed and shorter ripening period of rice crop appeared in 1996 compared to in 1995. It was due to higher growing degree-days, sunshine hours and solar radiation during rice growing season in 1996. Dongjinbyeo rice showed higher yield than Nonganbyeo which had lower ripened grains especially in 1995.

  • How is the "Yonsei University Incident" of August 1996 remembered from a periphery perspective and a gender perspective? With this question in mind, I reviewed the history of the revolution and the missing memories in the period from 1996 to 2016 in Korean literature. I tried to recover the story of the revolution experienced and remembered by those who were politically invisible or gender-excluded, by centering on novels with strange reminiscences of the student movement in 1996, namely Yoon I-Hyung's "Big Wolf Blue" ("Big Wolf Blue", 2011), Choi Eun-Young's "Responsibility"(2018), Hwang Jung-Eun's Didi's Umbrella (2019) and Park Sang- Young's "A piece of Rockfish Sashimi The Taste of the Universe"(How to Love in Metropolis, 2019). There is a correlation between the perception of the periphery and the name of the "unrememberable" revolution. And this fact tells us that revolution does not mean the same thing to everyone, even when it "passes" through the midst of a revolution that shares the imagination of a better society and the desire to reorganize the system. In other words, it emphasizes that the logic of exclusion and hierarchy was still in operation even at the moment of revolution. It would be said that this review is not only a rethinking of the student movement, but also a reevaluation from the gender perspective of Korean society in the 1990s.
