  • This experiment was carried out to investigate effects of herbicide application method on Calysteria jcqoonica control and corn yield at the forage experimental field, grassland and forage crops division, National Livestock Research Institute, RDA, Suwon from 1996 to 1997. The experiment was arranged in a randomized block design with three replication. The herbicide application consisted of control, 2~3 leaf stage(Dicamba), 5~6 leaf stage(Dicamba) and soil treatment (Pendimethalin). The hybrid of corn used in this experiment was P 3352. The results obtained are summarized as follow; 1. The plant height was the lowest at control and the highest at Dicamba treatment in 5~6 leaf stage, but no significant difference was found among herbicide application method at ear height. Tasseling and silking date were delayed 2~3 day at control. The length and weight of ear were highest at Dicamba treatment in 2~3 leaf stage. 2. The herbicide injury of corn was very slightly after 10-20 day, but corn was recovered soon. The weed control value was 94.2~67.5% at herbicide application plot. 3. The fresh and dry matter yield of Dicamba treatment in 2-3 leaf stage was highest as 42,878 and 16,033kg/ha, respectively. The application of Dicamba increased the DM yield of corn by 13~30%. 4. Herbicide application time had little effect on the ADF, NDF and CP contents, but the forage quality of ear was higher than that of stover. The result of this experiment indicate that the application of Dicamba in 2~6 leaf stage of corn will remove almost all of Calysreria jqonica and increase DM yield of com.

  • The Korean government has a new system for charging patient care for patients in hospital, on hold for the present(9 / 1995) but to start implementation in certain areas of patient care next year. From the latter half of next year the Ministry of Health and Welfare would like to start demonstration projects for hospitals who want to start using DRGs for frequently seen medical diagnosis and for patients with a course that is predictable and for whom non-insurance costs are minimal : such as the patient who has a delivery, cesarean deliveries, cataract surgery, tonsillectomy or an appendectomy, and apply the DRG system of payment for hospital care for these patients. The purpose of this study was to establish a recording system to give effective home health care to postpartum women and their newborns. Recently the government announced a DRG system to apply to postpartum women for pilot purposes starting next year. This gives impetus to the need to develop home care records that will allow for systematic recording and provide continuity and consistency in care across all health professionals and with in-depth communication between the professions to assure high quality care. There has been a rise in medical costs and a shortage of patient bed space in hospitals, particularly since the introduction of national medical insurance. The study focused on developing client selection criteria, a primary assessment tool, progress notes and nursing diagnoses applicable to postpartum and newborn clients. Selection criteria for home health care, assessment tool content, nurses progress notes and diagnoses were developed through a review of the literature, advice from professionals who are expert in home health care and actual practice in the use of recording tools through workshops. The recommendations based on the research results are as follows : 1) Replication and application of these tools is needed to test the validity of the tools 2) In order to have systematic nursing records standardization of records has to be done after nurses have had experience using them. 3) Reliability and validity of the tools has to be established through applicability to actual care situation.

  • The objective of this study was to test the pollutant reduction effect by the silt fence and vegetated ridge through field monitoring. The experiment plots were established with two replication and three treatments. Each plot was designed with 5 m width, 22 m length, and 3 % slope. Flumes with the floating type stage gages were installed at the outlet of each plot to monitor the runoff. For a rainfall monitoring, tipping bucket rain gage was installed within the experiment site. Cultivated crops were spring daikon and autumn chinese cabbage. Analysis of variance (ANOVA) indicated that the water quality concentration from three experiment plots were not significantly different in 5 % of significant level. The monitoring results showed that the average pollution loads reduced by silt fence compared to control were SS 75.33 %, TN 40.87 %, TP 56.58 %, BOD 52.12 %, COD 36.07 %, TOC 34.99 %; by vegetated ridge compard to control were SS 65.27 %, TN 81.80 %, TP 54.26 %, BOD 67.09 %, COD 46.55 %, TOC 43.30 %. Analysis of Spearman's rank correlation coefficient showed that BOD-SS and SS-Turbidity were highly related at the silt fence and vegetated ridge plots. In all plots, SS-Turbidity and TP-TN relations were relatively high. The monitoring results showed that the silt fence and vegetated ridge were effect method to reduce the pollutant loads from the field runoff. Long-term monitoring is required to obtain more quantitative reduction effect for diverse crops and to increase the reliability of results.

  • The purposes of this study were to describe systemically 18 years of oncology nursing research in Korea and suggest it's direction in future. 149 nursing studies published from 1980 to 1998 were selected for the present study. There were examined the source and the design of study, type of subjects, measurement variables, the intervention outcome of experimental research, and theme of qualitative research. The results were as follows : 1. 121 of 149 studies were composed of master thesis and dissertation of graduate school. There were 55 correlations, 30 descriptions, 19 comparisons, 19 qualitative studies and 2 Q-methods as the type of research design. 2. Cancer patients without describing specified diagnosis as subjects' characteristic were 44 of total studies. The others had various diagnoses such as gastric cancer, uterine cancer, breast cancer, leukemia, lymphoma, colorectal cancer, and lung cancer. According to treatment type, patients receiving chemotherapy were the highest number distribution as 53 of all researches. 3. Most measurement instruments used for research were translated it into Korean that developed by foreigners, such as Zung's depression, Spielberg's anxiety, and Wallston's locus of control. 4. Quality of life was shown the most frequently among correlational researches. the next one was depression, the third was hope, and so on. 5. There was the most frequent comparison between cancer and non-cancer patients in comparative researches. It was surveyed those variables as diet habits, risk factors, stressful life events, anxiety and depression, and self-care capacity between two groups. 6. The subjects were mostly chemotherapy patients as 15 of 24 experimental studies. Oral care and education were respectively the highest experimental interventions. 7. Qualitative researches about cancer were reported since 1991. Their themes were illness experience, adaptation process, dying experience, family experience, hope, caring, experience of health behavior, meaning of chemotherapy and experience of cancer survivor. Phenomenologic methodology was designed above 50% of qualitative researches. According to the above findings, cancer research had increased since 1990 and done mostly by descriptive design but a few experimental studies. As recommendations for the future, It is necessary to study the comparison of oncology nursing research internationally, the replication to establish the effect of nursing intervention, and the family care of cancer patient.

  • The purpose of this study was to defined mothers perception of their infants when the babies were high - risk babies, and to describe the feelings and responses of the mothers following on the birth of high - risk babies and on their hospitalization. The subjects of the study were 30 mothers of high-risk infants at D and M Hospital of E University. Data were collected between August 1993 and June 1994. Using the Neonatal Perception Inventory(NPI ) devised by Broussard to determine the perception of mothers and an open-ended, semi-structured interview which was conducted in the nursery room within 24 to 72 hours after delivery And NPI tested 1 month after the babies were discharged from the NICU also. Data were analyzed using SAS and content analy-sis. The results of this study are as follows ; 1. The mothers tended to perceive their infants positively, regardless of the condition of the infant. Mothers who perceived their infant negatively were slightly increased at 1 month after the babies were discharged from the NICU, but the difference was not statistically significant. 2. Mothers reported that they thought that the newborn can see and hear well, and also they can ex-press themselves. 3. There were many types of response noted such as anxiety, fear, helplessness, pity, resentment, guilt, resignation, hope, relief, appreciation, and feelings of being able to overcome the situation. These were differentiated into positive and negative responses. The finding of positive responses being expressed by mother of high -risk infants while their infants were in NICU was a unique finding especially, appreciation and feelings of being able overcome the situation. The results suggest the need for replication studies and for research on nursing interventions directed at improving the quality of life of high-risk infants and their mother.

  • Two experiments were carried out to evaluate the effects of adding phytase on nutrient availability and serum Ca and P level and to determine the effects of phytase on laying performance and egg quality in laying hens. In Exp. 1, twenty four laying hens(1.9kg average body weight and 78.4% egg production) were allotted to four treatments. Treatments included 1) corn-soybean meal based-control diet and 2), 3) and 4) control diet with phytase 200, 400 and 600 unit/kg, respectively. There were no significant effects of treatments on dry matter and nitrogen digestibility(P〉0.05). Ash, Ca and P digestibility in layer fed diet with phytase were greater than those in layer fed control diet(P〈0.05). Laying hens fed diets with phytase 200 and 400 unit retained more Ca than those fed other treatments (P〈0.05). No statistical difference was found for Ca exsretion(P〉0.05). P retention was greater for laying hens fed diet phytase 600 unit than other treaments(P〈0.05). P level in serum was higher for laying hens fed diets with phytase 400 and 600 unit than for laying hens fed other treatments. In Exp. 2, three hundred, IAS Brown layer, 40-week-old, divided into two treatment groups(control vs phytase supplementation without inorganic phosphate in the diets) with five replications per treatment and 30 layers per replication were fed the diets for 6 weeks. Egg production, egg weight and eggshell breaking strength and thickness were not different significantly(P〉0.05). In conclusion, phytase supplementation can be used to increase P utilization and retention in laying hens. Also, phytase supplementation was effective to spare inorganic phosphate in laying hen diets without any adverse effects on production performances.

  • High-quality multimedia on the Internet has attracted attention because of its wide application area. IP multicast has been proposed as a solution to use efficient network resources in these services. However, IP multicast has not been commonly used due to a number of practical issues such as security and management. As an alternative, an overlay multicast routing which is performed in upper protocol layers on legacy networks without changing hardware has been presented. Yet, the maximum data transmission capacity of the overlay multicast is not sufficient for real time transmission of multimedia data. In this paper, we have implemented an overlay multicast engine on NetFPGA which allows us to perform packet replication and tunneling which need high-speed. In addition, we have implemented extra portions which need low-speed in software. From now on, we will progress research which increase the number of terminal spots which can be replicated by improvement and amplify throughputs by optimization.

  • Fetal bovine serum (FBS) is an essential element of cell growth and can also affect the viral replication. In this study, we tried to find out whether FBS concentration affects the viral infectivity titer of IHNV and IPNV. EPC cells were suspended with MEM supplemented with various concentrations of FBS (MEM0, MEM2, MEM5 and MEM10) and cultured in 96-well plate. Each virus was 10-fold diluted virus and inoculated in 96-well plate. The highest infectivity titer of IHNV was $10^{7.88}\;TCID_{50}/mL$ in 96-well plate using MEM5 and the lowest one was $10^{7.30}\;TCID_{50}/mL$ in 96-well plate using MEM10. The highest infectivity titer of IPNV was $10^{7.47}\;TCID_{50}/mL$ in 96-well plate using MEM5 and the lowest one was $10^{6.97}\;TCID_{50}/mL$ in 96-well plate using MEM10. This study showed that not only 0% FBS but 10% FBS leads low infectivity titer of IHNV and IPNV. Therefore, it is considered that the desirable concentration of FBS is 2% or 5% for measurement of infectivity titer of IHNV and IPNV.

  • From the Darwinian perspective, all the human behaviors and thoughts are operated by "the selfish gene," the term coined by Richard Dawkins, which has long been evolving to survive by utilizing the limited quality and quantity of resources. And an organism which fails to regenerate by creating its "replicator" is doomed to extinction, for gene combinations which help an organism to survive and reproduce tend to also improve the gene's own chances of being passed on through generations. Dawkins also coins the term "meme" for a unit of human cultural evolution analogous to the gene, suggesting that such selfish replication may also be the principle for human culture. Ian McEwan is not only a controversial but more importantly influential writer in the 21st century academic world. His 1997 book Enduring Love is not exceptional in that it draws both literary and scientific attention. Intentionally set up with the dynamic conflict between the two cultures, namely art and science, the book explores the way in which the state of the modern minds is misinterpreted and estranged by each other. In this novel, the three main protagonists, Joe, Clarissa, and Jed, each representing the very important three elements of human civilization-cognition/science, emotion/art, and faith/religion-meet an unexpected peril of life. The author of the novel employs the narrative of evolutionary science-in particular the narratives of gene and meme-to provoke the question of the two cultures famously addressed by Snow in the mid 20th century and the further discussions followed by the later Darwinian scholars such as Richard Dawkins. In this paper I aim to illustrate the way in which the author develops the idea of gene science and literature and how he proceeds to provide a sophisticated bridge between the two cultures and induce a kind of consilience by the recurrent name of love in the story of Enduring Love.
