This study seeks to clarify the background and factors for the expansion of bus networks that connect Incheon International Airport with its hinterlands. For this research objective, this paper analyzes the relationships among the change of bus routes, competitive transportation modes, passenger fares, and the shortest time distance. Previously, the hinterlands of route bus networks that connect Gimpo International Airport were Seoul metropolitan area, Chungcheong region, Jeonju and Iksan in Jeollabuk-do(province). However, the opening of Incheon International Airport resulted in the expansion of the hinterlands of bus networks to Gangwon-do, Gwangju, and major cities in Youngnam region. Simultaneously, route bus networks also expanded in Seoul metropolitan area. Each bus route connecting Incheon International Airport with its hinterlands was opened by a single bus company or various bus companies. In many cases, due to the uncertainty of revenues or bus company's regional ties, a bus route was opened by various bus companies. In this paper, the analysis of the number of one-way route bus service and density of flight passengers shows that the frequency of the route bus service for Seoul except Gangseo-gu(ward) and for Seoul's satellite cities(Suwon, Seongnam, Anyang, Gunpo, Guri, and Osan) should be decreased. The analysis also shows that the frequency of the route bus services for the other cities, counties(Guns), and wards(gus) should be increased. In Seoul metropolitan area, although route bus fares are more expensive than subway fares, passengers use route bus more frequency than subway because time distance of route bus is shorter than that of subway and subway transfer is inconvenient. In general, outside Seoul metropolitan area, air flight is preferred in the regions that have airports. In contrast, the route bus is preferred in Daegu and other regions that do not have airports.
Background: The aim of this study was to examine the association of serum isoflavones, adiponectin, and insulin levels with ovarian cancer risk. Materials and Methods: We gathered cases with histologically confirmed epithelial ovarian cancer at Sapporo Medical University Hospital from October 2010 to September 2012. Potential controls were recruited from female inpatients without any history of cancer or diabetes mellitus in different wards of the same hospital over the same period of time. Serum isoflavones, adiponectin, and insulin levels were measured in order to estimate associations with ovarian cancer risk in a case-control study. Data from 71 cases and 80 controls were analyzed with a logistic regression model adjusting for known risk factors. Results: A significant reduction in ovarian cancer risk was observed for the high tertile of serum daidzein level versus the low ($P_{trend}<0.001$). A significant reduction in ovarian cancer risk was also observed for the high tertile of serum glycitein level versus the low ($P_{trend}=0.005$). Furthermore, a significant reduction in ovarian cancer risk was observed for the high tertile of serum adiponectin level versus the low ($P_{trend}=0.004$). Conversely, serum insulin level showed significantly elevated risk for ovarian cancer with the high tertile versus the low $P_{trend}<0.001$). Conclusions: Decreased serum isoflavones levels, such as those for daidzein and glycitein, decreased serum adiponectin levels, and increased serum insulin levels could be shown to be associated with elevated risk of ovarian cancer.
The environment in the ICU leads to negative changes in a patient's usual sleep pattern and so contributes negatively to the patient's health condition as compared to patients in general wards. Therefore, it is thought that an important nursing intervention would be to identify the relation between noise and sleep patterns which play an important role in illness recovery. The purpose of the present study was to explore the relationship between noise in the ICU and the sleep pattern of patients admitted to the ICU. A descriptive correlation design was used to examine the relationship. Thirty-four subjects were recruited from a Medical ICU (MICU), Surgical ICU (SICU) and Coronary Care Unit (CCU) at a large university hospital in Suwon. Data were collected from September 28 to October 31 in 1999. In the present study, noise was categorized into noise level and patients' perception of noise. The objective noise level was measured using the A-Weighted Sound Level Meter. The patients' preception of noise was measured using a self-reported questionnaire developed by the researcher. Sleep patterns in this study includes both quantity and quality of sleep. These were measured using open ended questionnaires and the 'Korean Sleep Scale A' developed by Oh, Song, Kim(1998). The data was analyzed using the SPSS-WIN to test the research question, Pearson product moment correlation coefficient was run. Ancillary analysis were conducted with demographic variables to determine their relation to the main study variables. For the ancillary analysis, t-test and one-way ANOVAs were performed. The results of the present study are summerized as follows : 1. The total mean of objective noise level (10pm-6am) was 56.2dB. The means for night time noise level in individual ICUs for the SICU, MICU and CCU, were 58.7dB, 58.6dB and 48.3dB, respectively. The total mean for patients' noise perception was 42.8 out of a maximum possible score of 76. For item means of noise perception, the one ranked highest was "conversations between doctors and nurses" (3.2). The one ranked lowest was "noise from the radio" (1.2). Regarding the degree of perception for each type of noise source, the one ranked highest was "equipment noise" (2.6), the second was "conversation between medical staff" (2.4), the third was "conversation between patients, caregivers and visitors" (2.3), and the one ranked lowest was "environment noise" (1.8). 2. Looking at quantity of sleep of ICU patients, the mean nocturnal sleep time was found to be 4.9 hours. The total mean of sleep quality for ICU patients was 21.0 out of a maximum possible score of 40. 3. The relationship between perception of noise and quantity of sleep was statistically significant(r= - .41, p<.05). The relationship between perception of noise and quality of sleep was also statistically significant(r= - .47, p<.01). The results of the study indicate that personal perception of noise is related to sleep patterns. Therefore, it is suggested that nursing interventions be developed to reduce the degree of personal perception of noise and, thus, decrease sleep pattern disturbances in patients in the ICU.

Legionella spp. is the causative agent of Legionellosis, which induces a potentially fatal form of pneumonia. With a concentrated performance during the summer of 2008, we secured 73 isolates from the water systems of 25 wards in Seoul. We analysed serotypes, pathogenic genes (Dot/Icm), and patterns of pulsed-field gel electrophoresis (PFGE) in an attempt to confirm relationships among them. Different from the previous year's pattern (2007), among the isolates, 69 were Legionella pneumophila and 4 were Legionella spp. The serotype distribution of Legionella pneumophila was sg1 43, sg6 9, sg5 8, sg3 8, and sg2 1. The serotype for the 4 Legionella spp. was Legionella nautarum. Most of the Legionella pneumophila had several pathogenic genes. On the other hand, the 4 Legionella spp. were defective in pathogenicity in genomic terms. The PFGE patterns of the serotypes showed a tendency for diversity of Legionella pneumophila and a close correlation with genetic pathogenicity.
The study was performed to investigate the bacteriological contamination of portable digital radiography system and their detectors in a university hospital. CNS and VRE were detected in the samples collected from vinyl cover on detectors used for the infection control patients. On the other hand, no bacteria was detected in the samples collected from detectors with vinyl cover removed. In the series of imaging of patients from general wards, no bacteria was detected from the patient 1. However, CNS was detected from the patients 2 and 3, CNS and Enterococcus faecalis detected from the patient 4, CNS and Enterococcus casseliflavus detected from the patient 5, and CNS, Enterococcus casseliflavus, and Klebsiella pneumoniae all detected from the patient 6. CNS and Enterococcus faecium were detected in the controller handle of collimator. Also, CNS was detected from the handle of detector and exposure switch. In the treatment gloves of the radiological technologist after the imaging, CNS, Enterococcus gallinarum, and Klebsiella pneumoniae were detected. Therefore, it is recommended for DR portable to take images after sterilizing the detector after taking each image and to use disposable vinyl covers on detectors to remove after imaging. And treatment gloves must be changed after each imaging. Also, hospital infection via portables must be prevented by complete sterilization of the controller handles of collimator which are in frequent contact during imaging and infection education of employees.
In this study noise source in a ward at four general hospitals in Seoul area has been investigated and analysed. The degree of reaction against noise by 171 randomly has also been examined. The results of the study have shown that the source of noise is the speakers of wired broadcasting or from visiting guests in two hospitals located in residential area. The patients at the two other hospitals located at commercial site have been suffered more from traffic noise. However, because of their separated living at hospital from their ordinary houselife, sixty one percent of the inpatients have wished a music sound of around 60 dB (A). After having considered the results of the investigation and wishes of the inpatients, following suggestions have been made: 1. Reduce the number of guests or their length of stay. 2. Wired broadcasting system should be substitued by wireless one, or if it's unavoidable, it should be used in office rooms only. 3. Since the stops and starts of vehicles induce much noise, Seoul City Government be requested to prepare an appropriate administrative measure for the vehicles around hospital area and it should prevent the establishment of new hospitals along high way site. 4. By using earphone, inpatients can choose a wireless channel according to each individual's taste. This through the masking effect, would cover up the noise source. 5. Rooms along the streets should be utilized as offices, otherwise double windows should be set up for inpatient's wards.
The purpose of this study was to investigate on paid hospital-nurses' work perception, knowledge, performance and the performance-related factors of a nurse who works in a hospital with no guardian which is phased in its beginning as well as interactions between the factors. Data were collected from nurses working in wards without guardian at 9 hospitals among a total of 10 Korean hospitals carrying out a national pilot project which is designed for institutionalization of national caregiving services. Self reported questionnaires were used to collect data from 167 nurses, and 135 returned forms were analyzed(December, 2010). The score of perception was 4.24/5.00, knowledge 4.25/5.00, and performance 3.49/5.00. The performance was significantly different depending on the hospital types(p=.002). Significant correlations were found among perception(p<.001), knowledge(p=.004) and performance. The degree of perception(p<.001) and types of hospital(p<.001) attributed to 16.5% of variance in the practice. To enhance level of performance by taking account of perception and types of hospital, can be effective for hospital-nurses when there is no guardian.
The purpose of the present study is to confirm the interacting behavior between nurses and patients and other things concerned herewith. Subjects of investigation were : 42 nurses selected out of the average nurses who serve in hospital as nurses assigned to medical and surgical wards : and 42 male and female adult patients selected out of the average patients who were under the care of the nurse individuals and can make themselves understood verbally. A nurse and her patient were paired off for questioning. Materials for statistics were gathered by means of observaing interactions- - verbal and nonverbal - -of the chosen subjects for four hours every day from 7 : 30 a.m. through 7 : 30 p.m. between on July 15, 1988 and on Aug. 16, 1988. Classified by patterns, the materials observed and gathered were preliminarily analyzed by this researcher, and then reexamined in a full-fledged way by one professor, three nurses and three non - nurses. The researcher depended chiefly on Frequency, ANOVA, Pearson's Correlation Coefficient attached to SPSS Computer System for the process of gathered materials. The results of this investigations are follows 1) A total of 98 times' interactions between nurses and patients were provided during observation of 168 hours. 2) It took them the averaged 264.8 seconds(around 4.4 minutes) per a couple of subjects to interact between nurses and patients during observation of four hours. 3) The aim of interactions between nurses and patients appear that 29 times of injection amounted to 29.6% the most, 27 times of PO around to 27.6% the next most, 25 times of vital check to 25.5% the next most, 17 times of independent nursing works and round to 17.3% the least most. 4) As a result of qualitative analyzing the interactions between nurses and patients by the distinctive method of words were positively recognized in 19 cases with 45.2% and negatively in 23 cases with 54.8%. 5) A total of 2, 193 times. interaction behaviours between nurses and patients were provided. The frequency of these interaction behaviours took place l, 364 times with 62.2% to nurse, and 829 times with 37.8% to patients. 6) The classification of verbal and nonverbal interaction behaviour between nurses and patients indicated that it is amounted to 64.9% for verbal behaviour numbered 1, 423 and 35.1% for nonverbal one numbered 770. 7) The frequency of verbal behaviour between nurses and patients numbered 1, 423 in total. They took place 924 times to nurses and 499 times to patients, it can be also amounted to 64.9% and 35.1% respectively in percentagewise. 8) In interactions between nurses and patients, it turned out that the frequency of nurses' turns, which the present research discovered averaged 16.8 times for four hours, and the verbal behaviours by numbered 9.7 on an average. 9) Nonverbal behaviours between nurses and patients numbered 770 in total, it is assigned 440 times to nurse with 57.1% and 330 times to patients with 42.9%. 10) The investigation releases in formation that the frequency of verbal behaviours between nurses and patients was very much concerned with the age of patients(r=0.422, p<.01) and the number of patients one nurse has under her care(r=-0.356, p<.01). 11) It was found that were deep relationship of the number of a nurses turn with the patients age(r=0.377, p<.01) and the nurses burden of caring patients(r=-0.372, p<.01).
Background: Patients diagnosed with cancer tend to have multiple risk factors for drug related problems such as old age, comorbid conditions, self-medication, additional medications for supportive therapy, and the cancer treatment itself. Objective: The aim of this study was to investigate notable polypharmacy and related problems in oncology patients during hospitalization or following clinic visit. Method: The electronic medical records of patients who were discharged from oncology division at Seoul National University Hospital (SNUH) from June $1^{st}$ to June $30^{th}$, 2011 were retrospectively reviewed. Results: A total of 334 discharged patients were included in this study. Among them, 221 patients had pre-admission medications. Forty percent of the patients, including 60.3% of elderly patients (over 65 years of age) were prescribed more than 5 kinds of medications. Twenty percent of the patients were prescribed to take medications more than 7 times a day. Medication duplications were observed in 2.4% of patients. In 10.5% of the reviewed patients, 47 cases of potential drug-drug interaction including 3 cases of contraindication and 17 cases of major clinical implication according to Micromedex were detected. Medication changes were made in 88% of patients during hospitalization and in 94.7% of patients at their first visit after discharge. Antidiarrheal agent (loperamide) was prescribed along with laxatives in 18.5% of the prescriptions and inadequate instructions on how to take it were observed in 63% of the prescriptions. Conclusion: This study identified the prevalence of polypharmacy and related problems in cancer patients, which presents the need for an active role of pharmacists in pharmaceutical care in oncology wards.
To investigate the effects of paper sludge on the seasonal variations of higher fatty acids in paddy soil, paper sludge was applied to pots at the rate of either 300, 600, 900 or 1,200kg/10a. Fractions of the higher fatty acids in the soil were analyzed. 1. Twenty-one kinds of higher fatty acids in the soil were detected. Among them, lauric, myristic, myristoric, palmitic, palmitoleic, stearic, oleic, linoleic, linolenic and arachidic acids were identified. The fatty acid content in the soil of acids, linolonic, myristic, palmitic, and stearic acid increased in ascending order. 2. The total content of higher fatty acids in the soil was increased as the application of paper sludge increased. The formation of the acids was at its highest point at the effective tillering stage. After WARDS the contents of the acids decreased as time elapsed. A positive correlation was observed between the total contents of both higher and volatile lower fatty acids in the soil.
