Coastal fisheries in Korean waters have highly complexity with a variety of fishing gears, and scale of those fisheries is smaller than that of offshore fisheries. As a result, important spawning and nursery grounds for many species of fish has been destroyed. The pragmatic ecosystem-based approach was developed for the assessment of fisheries resources in Korean waters by Zhang et al. (2009; 2010). As for the species risk index (SRI), common squid caught by coastal gillnet in the Uljin region had the highest risk. As for the fisheries risk index (FRI), coastal gillnet in the Uljin coastal waters had the highest risk. For the common squid which had the highest SRI, resources management strategies must be established such as catch prohibition of length and period with TAC. For the coastal gillnet in the Uljin region which had the highest FRI, it is judged to need management plans for conserving biodiversity as reducing the catch of non-target species and discards. Also to protect existing habitat, illegal fishery should be prohibited, and fishing gears should be designed in the environmental-friendly way considering when fishing gears lost.

Purpose: In Kyung Hee East-West Neo Medical Center, Seoul, Korea, efforts to raise rooming-in care success rate have been undertaken since when the hospital was established in 2006. We intended to analyze our experience over the past 3 years of period and to discuss the advantages of rooming-in. Methods: We analyzed the rooming-in practice rate, failure rate, and the breast feeding rate. Subjects were 860 normal healthy neonates from June 2006 to June 2009. Results: Among these 860 cases, 83 babies were required separation out of rooming-in in the middle of the course. Among these 83 cases, 70 cases had to stop the course due to poor condition of babies and 13 cases due to maternal condition. 70 cases of infant's causes consist of 68 cases of NICU admission and 2 cases of poor feeding support. The other 13 cases of separation include refusal by maternal condition. Therefore the success rate of rooming-in for the last 3 years was 90.3%, that is 777 cases among the total 860 cases. The percentage of exclusive breast feeding was 64%, that of mixed feeding with breast and formula feeding was 25%, and formula feeding only was 11%. Conclusion: We experienced successful rooming-in care for the last 3 years. Nursery facilities should educate and encourage the advantages of rooming-in, including the good formation of attachment between mother and infant, emotional stability, protection from infection, and increased breast feeding rate so that rooming-in care can be fully established.

Neonatal sepsis is a frequent and important cause of morbidity and mortality in the neonatal period. This study was undertaken to observe the 55 cases of proven neonatal sepsis among 6,717 newborn infants under 4 weeks of age, admitted to the nursery of Yeungnam University Hospital from May 1, 1983 to April 30, 1988. We observed following results : 1. The morbidity rate of male(1.12%) was higher than that of female(0.44%) significantly (p<0.05). 2. The morbidity rate of prematurity(2.65%) was higher than that of full term(0.76%) significantly (p<0.05). 3. The incidence of perinatal obstetric complications in early onset neonatal sepsis was higher than that of late onset neonatal sepsis (38.5% vs 10.3%, p<0.05). 4. The common clinical manifestations were poor feeding(52.7%), jaundice(45.5%), diarrhea(30.9%) and irritability (30.9%). 5. Among the causative organisms, gram positive organisms were predominated and Staphylococcus epidermidis was the most common organism. There was no difference in the causative organisms between early onset and late onset sepsis.

This study was carried out to select the utilizable vegetations for the stabilization of slopes and river banks, landscape creation and water quality cleansing in dams, lakes and streams. In this study, 10 herbaceous plants were investigated for their survival and growth characteristics under complete and partly flooding conditions in the nursery. The ranking order of flooding tolerance based on survival ability showed that Iris pseudoacorus, Phragmites communis and Phragmites japonica were first, Typha angustata, Miscanthus sacchariflorus and Pennisetum alopecuroides were second, and Cymbopogon tortilis, Miscanthus sinensis, Kummerowia striata and Lolium multiflorum were last. That of flooding tolerance base on growth ability showed that Iris pseudoacorus, Phragmites communis, Phragmites japonica, Typha angustata and Miscanthus sacchariflorus were first, Pennisetum alopecuroides, Miscanthus sinensis and Kummerowia striata were second, and Cymbopogon tortilis and Lolium multiflorum were last. Espcially, Miscanthus sacchariflorus, Iris pseudoacorus, Phragmites japonica and Phragmites communis showed good survival and growth abilities when they were complete flooded for 60 days. Also high flooding tolerant species grow as better as flooding period longer under the partly flooding condition. It was found that Pennisetum alopecuroides and Kummerowia striata have excess moisture tolerance because they showed good survival and growth under the partly flooding condition. This study confirmed that the possibilities of utilizing Iris pseudoacorus, Typha angustata, Phragmites japonica, Phragmites japonica, Phragmites communis, Miscanthus sacchariflorus, Pennisetum alopecuroides and Kummerowia striata as the efficient plants for vegetation measures on the flooded slopes of dam and various impoundment sites.

The aim of the study was to assess the efficacy of Toyocerin, a probiotic containing Bacillus toyoi spores, on the health status and productivity of pigs, during nursery, growing and finishing phases. On a commercial farrow-to-finish farm in Greece, 3 experimental groups were formed, each of 72 weaned piglets. The pigs of the first group (T1 group; negative controls) received normal feed with no antimicrobials or probiotics, the pigs of the second group (T2 group) received the same type of feed but supplemented with 1.0${\times}$10$^9$, 0.5${\times}$10$^9$ and 0.2${\times}$10$^9$ spores per kg of feed at weaning, growing and finishing stage, respectively, and the pigs of the third group (T3 group) were fed with Toyocerin at the dose of 1.0${\times}$10$^9$ spores per kg of feed during the entire fattening period (weaning, growing and finishing stages). The results have shown that, compared to the controls, Toyocerin treated pigs had reduced incidence of postweaning diarrhoea (p<0.05). Enterotoxigenic strains of Escherichia coli were detected in faecal samples of 0% to 25% of pigs of the treated groups, but in 33.5% to 50% of pigs of the non-treated group (p<0.05). Over the negative controls, a significant improvement of weight gain (4.5% and 8.3% for T2 and T3 groups, respectively), and of feed conversion ratio (6.6% and 13.0% for T2 and T3 groups, respectively) was observed. The 76.5% of the carcasses of the T3 group was classified in the top three categories of the EUROP scale (S, E and U), whilst the respective figures were 47.8% for T2 group and only 10.5% for T1 group (p<0.05).

Background: Many scientists have reported Candida species to be of great concern because of the high frequency that they colonize and infect human hosts, particularly cancer patients. Moreover, in the last decades Candida species have developed resistance to many antifungal agents. Based on this, we aimed to identify and determine the prevalence of Candida spp from blood culture bottles among cancer patients and their antifungal resistance pattern. Materials and Methods: From the blood culture bottles isolation and identification of the Candida spp were performed by conventional microbiological techniques. The in vitro antibiotic resistance pattern of the isolates was determined by CLSI guidelines. Genomic DNA was isolated and amplified. Each gene was separated by agar gel electrophoresis. Results: Identification of Candida spp was based on the presence of yeast cells in direct examination, culture and DNA extraction. Of the 68 blood samples collected during the study period (April 2013 to October 2013), five (7.35%) were positive for the presence of Candida spp, 2 (40%) of which were identified as Candida albicans and 3 (60%) were Candida non-albicans. Conclusions: High resistance to amphotricin B was observed among all the Candida non-albicans isolates. Regular investigations into antifungal resistance will help us to get an updated knowledge about their antibiotic resistance pattern which may help the physician in selecting the antibiotics for empirical therapy.

One of the most laborious work in rice farming is transplanting of rice seedling which has been required preparation of nursery bed and care of seedling during one month period. In this research, direct seeding in dry paddy(DS) and direct seeding in wet paddy(WS) were practiced to compare with traditional transplanting(TP) in Suwon. Growth stages in direct seeding were delayed as its planting time was about 21 days later than those of TP. Heading stage of direct seeding at Suwon was delayed about 9 days as compared to transplanting culture. Rice yield was not different between the seeding practises. Working-hour saving was about 17％(DS) and 28％(WS). Production cost of direct seeding was decreased 20％(DS) and 32％(WS), respectively. Amount of rice production per a unit working-hour in direct seeding could increase 14％(DS) and 39％(WS) compared to that of TP, respectively. Therefore, direct seeding could save significantly working hour and production cost without reducing rice yield. WS was more effective than DS in saving labor and production cost. Direct seeding was not efficient method in input of farming energy and agricultural chemicals.

We analyzed annual and seasonal variations in fish species composition and distribution patterns using both daily catch and quantitative analysis data collected from a set-net fishery over a period of two years (2011-2012) on the coast of Dapo, Geoje Island. Set-net fishing season in this area is from May to November, and the annual yield based on the daily catch data was 171,412 kg in 2011, and 102,611 kg in 2012. In total, there were 46 species (belonging to 36 families and 12 orders) in 2011, and 41 species (belonging to 25 families and 9 orders) in 2012. The dominant species in terms of numbers were Trachurus japonicus, Engraulis japonicus, Clupea pallasii, Scomber japonicus, and Sphyraena pinguis. The range in fork length for T. japonicus and E. japonicus was from 3.2 to 23.9 cm, and from 2.6 to 13.3 cm, respectively. The fork length of recruiting juveniles to the Dapo set-net fishing ground ranged from 4.6 to 7.8 cm (median) for T. japonicus, and from 4.1 to 5.0 cm (median) for E. japonicus. The fact that most of the fish caught from the two species were at immature growth stages implies that the coast of Dapo can act as a nursery area for these migratory species.

Purpose: Assessment of mothers' neonatal perception is important in understanding early mothering experiences and in planning future care. The purpose of this study was to identify the differences of mothers' perception and caring-confidence between normal and high-risk newborn during the early postpartum period. The ultimate goal was to contribute to healthy mother-infant relationship and development of infants. Method: The data was collected for this study at one university hospital in Daejeon from May 13, 2005 to December 20, 2005. The subjects were 53 of mothers who had normal newborn and 46 of mothers who had high-risk newborn. The instrument was the 'Neonatal Perception Inventory' by revised Ja-Hyung, Lee (1986), and the 'Caring-Confidence Scale' by revised Hyun-Joo, Oh(2000). The data were statistically analyzed by using an SPSS program and include percentage, mean, SD, t-test. Result: There were significant differences in the perception of the newborn between the mothers of normal newborn and the mothers of high-risk newborn (p<.05). There were no significant differences in the perception pattern of the newborn between the mothers of normal newborn and the mothers of high-risk newborn. There were no significant differences in the caring-confidence between the mothers of normal newborn and the mothers of high-risk newborn. Conclusion: The nursing care in the nursery have needed to various interventions for normal and high-risk newborn mothers in order to improve the interaction and caring-confidence between mother and newborn.

The occurrence of Fusarium wilt in strawberry fields in Korea was assessed from 2001 to 2003. Fusarium wilt was found from June to August in nursery beds, from September to October after planting in production beds, and from January to March during harvesting period. The symptoms were root rots, discolored vascular tissue in the crown and deformation and yellowing of central leaflets. The disease occurred in up to 30% of plants in 37 of 214 fields surveyed. Fusarium wilt occurred from cvs. ‘Dochiodome’, ‘Maehyang’, ‘Redpearl’, ‘Samaberry ’ and ‘Akihime’ and more severe from cvs. ‘Samaberry’, ‘Maehyang’ and ‘Dochiodome’. Infested soils had high salt concentrations, high nitrogen, phosphate concentrations and low pH. The results of pathogenicity test showed that Fo47 and Fo79 isolated from cvs. ‘Dochiodome’ and ‘Samaberry’ were strong pathogenic to all of four cultivars, and ‘Dochiodome’, ‘Redpearl’, ‘Maehyang’ were relatively susceptible to the all isolates.
