Contamination levels of pathogenic microorganisms in 145 cases of beef, which were distributed in Gwangju province, had been investigated in each distributed stage and also monitored by general bacterial count and E coli count index. General bacterial count of beef from the slaughterhouse was 10$^4$cfu/g less than the level of promotion(10 cfu/$\textrm{cm}^2$) and E coli count index was also under the level of 10$^2$cfu/$\textrm{cm}^2$ recommended level of the ministry of agriculture and forestry. Pathogenic microorganisms were detected from 23.2% of samples in the consumption stage, 12.5% in the slaughtering stage and 5.6% in the transporting and processing stage. Staphylococcus aureus was isolated in the largest number and its ratio was 9.0%, listeria monocytogenes 5.5% and salmonella spp 1.4%. There were no samples that bacteria had been detected dually. E coli O157:H7 and campylobacter jejuni were not isolated. In raw and chilled beef, isolation rate of pathogenic microorganisms were 13.3% and 16.5% each. Especially in raw beef, L monocytogenes was. isolated in 3 samples among 30 cases (10%) and S aureus in one sample (3.3%). According to a scale of meat store, isolation rates of pathogenic microorganisms were different. It was 28.6% in the small-scale meat store and 16.7% in the large-scale meat store each. Four cases (16.7%) of S aureus were isolated in the large-scale meat store and seven cases (20.0%) of L monocytogenes and 2 cases (5.7%) of salmonella spp were isolated in the small-scale meat store. S aureus was isolated in two places among 10 feeding facilities of the elementary school. This result shows that the sanitation of elementary school feeding facilities is so poor and more careful policy consideration is needed. Eleven strains of S aureus isolated showed ${\beta}$-hemolysis on blood agar, 1 strain ${\alpha}$-hemolysis, and 1 strain ${\gamma}$-hemolysis. Isolated strains of L monocytogenes were reconfirmed in 560 bp by PCR. Conclusively, these results show that the sanitary condition in the stages of slaughtering, transportation-processing and consumption influences the degree of pathogenic microorganisms contamination in beef severely It is necessary to apply thoroughly hazard analysis critical control point in a process of beef distribution and also to develop rapid test methods for microorganism diagnosis. This effort is very important for the supply of safe and clean meat from farm to table and helpful for the improvement of public health.

The management of nursing resource is very important. that is because nursing staff accounts for 30-40% of total staff in a hospital and nurses provide patoents with attentive service for hours daily. The continuous turnover of nursing staff. however, impedes the quality-oriented nursing care, which will consequently leads to the loss of human and material resource in competitive society. This study aimed to calculate nurse's activity and compare the activity amount based on career experience. Futhermore it aimed to find factors which would influence 'quality weighed direct nursing activity amount'. Questionnaires and check lists for this study were distributed to nurses in a suburban hospital outside of Seoul from October 20 to November 14. 1997. The nursing activities were calculated according to professionality. independency and working hour. And then it were accumulated by quality score. The collected data was analyzed by statistical methods as t-test, ANOVA, correlation, multiple regression. The results of this study were as follows ; Firstly, carrel' experience had no influence on the quality weighed nursing activity amount. But the quality level of service of skilled nurses was higher than that of new nurses. Secondly, career was a variable affecting the quality in nursing service. So career was positively related to the quality of nursing care. Patient's disease severity and number of patient were positively correlated with weighed nursing activity amount. But job satisfaction was negatively correlated v:ith the amount. Thirdly, the independent variables which had significant influence on the weighed nursing activity amount were disease severity and the number of patients, The severity score and number of patient were directly proportional to the weighed nursing activity amount. This results indicated· that weighed nursing activity amount was influenced by the number of patient and patient's disease severity. The quality score of nursing services for experienced members is higher than that of new staff. But both new and skilled staff showed no difference in the quality weighed nursing activity amount. Internal and. external environment influences nursing activities. The quality of nursing services is very important factor in nursing activity. Therefore nursing managers should make an effort to improve nursing care quality through continuous research. Also they should try to maintain experience nurses and assign nursing staff appropriately with patient's severity and other relevant factors being considered. The quality-improved nursing care in the hospital will strengthen hospital's competitiveness.

The purpose of this study was to discuss the nature of pregnancy experience among unwed Korean mothers and to figure out what it meant for them, by asking some of them to reflect on themselves in a written form from interpretative and phenomenological perspective, based on van Manen's research method of the same approach. The subjects in this study were seven unmarried mothers in Korea. The data were collected from July through December 2000 through in- depth interview and observation. The statements of the participants were taped, recorded, analyzed and select essential themes. To have a phenomenological understanding of the pregnancy unmarried mothers, literary works, including essays and novels, were reviewed. The findings of this study were as below: The selected substantial themes about the pregnancy and birth experiences of the single mothers included 'hatred for boy friend,' 'hatred for the fetus,' and 'hatred for myself.' The unmarried mothers met their boy friends through the introduction of friends. At first, they were good friends, but they soon went on a date and had sexual relation with no common knowledge about sex. Most of them were aware of their pregnancy after they felt fetal movement, but they put off taking the test because they didn't want to accept the fact and feared it. Such an attitude was rare among married pregnant women, and being pregnant with no prior preparation or sexual knowledge is not common in Western countries. They felt guilty and informed their boy friends of the fact, but the boy friends didn't admit their responsibility and rejected the babies. This made the poor girls hate them, and it turned into severe abhorrence. They thought their lives were ruined by the babies, and wished they would disappear. They reproached the babies, hitting their own bellies or making a kick. They considered themselves to be abandoned and didn't want to live any more. Giving themselves up to despair, some attempted to commit a suicide. They hoped to die, thinking their death would solve the problem. When they lost a chance of abortion and were about to have the babies adopted, they felt sorry for them. The unwanted pregnancy gave them a pain, but they keenly felt they were loved by their mothers, and learned the value of family. It's attempted in this study to clearly show how much unmarried Korean mothers suffered from pregnancy, and this effort paved the way for seeing unwed mothers in a new light and having a better understanding of them, instead of sticking to general perception.

Most banks in Myanmar have begun to provide their services via mobile phones. However, few studies investigated the factors that may help to set mobile services from a customer perspective. So, this study aims to propose and test a conceptual research model to predict the user's intention to use and actual use level of mobile banking service by combining UTAUT and DeLone-Mclean IS model. Data were collected from 206 citizens who had experienced mobile banking in various regions of Myanmar. The study found that performance expectancy, effort expectancy, information quality and service quality influence the user 's intention to adopt mobile banking services which directly affects the user's actual use of them. However, social influence, facilitating condition and system quality don't influence the user's intention. The study results contribute to meeting customer's needs and reducing customer risk in Myanmar's mobile banking industry, suggesting to seamlessly provide the necessary resources like technology improvements, organizational infrastructure and service centers. Another future study are required to include service's security and trust factors so that the service providers could gain their customers' reliability and trust.

The dynamic behavior of piles becomes very complex due to soil-pile dynamic interaction, soil non-linearity, resonance phenomena of soil-pile system and so on. Therefore, the proper numerical simulation of the pile behavior needs much effort and calculation time. In this research, a new modeling method, which can be applied to the conventional finite difference analysis program FLAC 3D, was developed to reduce the calculation time. The soil domain in this method is divided into a near-field region and a far-field region, which is not influenced by the soil-pile dynamic interaction. Then, the ground motion of the far-field is applied to the boundaries of the near-field instead of modeling the far-field region as finite meshes. In addition, the soil non-linearity behavior is modeled by using the hysteretic damping model, which determines the soil tangent modulus as a function of shear strain and the interface element was applied to simulate the separation and slip between the soil and pile. The proposed method reduced the calculation time by as much as one third compared with a usual modeling method and maintained the accuracy of the calculated results. The calculated results by the proposed method showed a good agreement with the prototype pile behavior, which was obtained by applying a similitude law to the 1-g shaking table test results.

This research focused on a total of 378 patients with external injuries under the age of 14 who visited the emergency center at a university hospital in Korea, during the months of January, April, August and November between January and December of 2007. In addition, the survey was conducted only on even number days and ranged across the whole year to reflect the impact of seasonal characteristics on the collected data. The research focused on determining the characteristics and inflicting cause of these patients with external injuries, analyzed the total time spent in the emergency room and obtained the following results. 1. When classifying the patients into different genders, the proportion of males (67.5%) was higher than that of females (32.5%). According to the different age groups, the highest ratio, at 61.1 %, was patients under the age of six. 2. Looking at the total number of minutes spent in the emergency room, the longest amount of time occurred during April with 162.7 minutes, followed by 121.9 minutes in January and 92.4 minutes in November. August had the shortest period of time spent in the emergency room, a significant statistical difference from the other periods of the year (p<0.001). 3. Regarding the amount of time required for each examination, patients required to provide a urine test spent an average of 204.7 minutes while those who did not spent 113.5 minutes on average. This is a 5% statistical difference among the two groups (p>0.05). 4. Looking at the five most commonly diagnosed problems in the emergency room, the total number of people with these top five commonly diagnosed illnesses comprised 55.6%, or 210 patients out of 378. 5. Utilizing the Decision Tree Model to estimate the total number of minutes required per visit, the first classifications were made using a chemical examination factor. People subject to chemical classification spent an average of 177.7 minutes, which was longer than the overall average of 115.2 minutes, and those exempt from chemical examination spent an average of 103.8 minutes, which was shorter than the average Conclusion; Effort to curtail the total time spent in emergency rooms is vital in guaranteeing efficient management of hospitals and providing medical services. The delay experienced by many comprehensive professional medical centers must be resolved through the establishment of effective delivery of medical services, increased supply of patient rooms and other policy oriented implementations. However, for now, this problem must be resolved by increasing the level of patient satisfaction and guaranteeing effective operation of patient rooms, which will significantly contribute to the general management and success of hospitals and institutions.

Recent improvements in the standard of living, national income and medical care, and a decline in the infant death rate which have occurred related to economic growth and modernization, have led to a longer average life-span and a higher ratio of elderly people in the total population, Therefore, not only in the field of nursing science, but also in the field of many other discipline, issues concerning the elderly have been given increasing interest. A great deal of effort has been spent on increasing the quality of life for elderly people. This study was conducted to analyze the correlation between social support and quality of life. The sample consisted of III subjects residing at home and 107 subjects residing in institutions all of whom were over 65 years of age. The data collection period was from October 23, 1990 to January 26, 1991. Social support was measured using the Norbeck social Support Questionnaire developed by Norbeck, translated by Oh, Ka Sil and quality of life was measured using the QOL scale developed by No, You Ja. Data were analyzed using pereentages, t-test, Pearson Correlation Coefficient and ANOVA. The results of this study are as follows : 1. There was a statistically signifivant difference in the level of social support between the two groups (t＝-8.83, p＜.001), The elderly at home reported a much higher level of social support. 2. There was a statistically significant difference in the level of QOL between the two groups (t＝-5.77, p＜.001) . The elderly at home reported a much more positive quality of life. 3. There was a positive correlation between social support and QOL for the elderly at home ard it was statistically significant (r＝.32, p＜.001). 4. There was a postitive collealtion between social support and QOL for the elderly in institutions and it was also statistically significant (r＝.19, p＜.05). 5. The relationship between the general characteristics of the elderly at home and the variables of social support and of QOL were as follows ; 1) according to sex(t＝10.57, p＜.01) and the number of offspring(F＝6.19, p＜.01), there was a statistically significant difference in social support. 2) according to amount of Pocket money, there was a statistically significant difference in QOL(F＝2.98, p＜.05). 6. The relationship between the general characteristics of the elderly in institutions and the two variables were as follows ; 1) according to sex(t＝6.24, p＜.05), the number of offspring(F＝6.16, p＜.001) and religion (F＝2.58, p＜.05), there was a statistically significant difference in social support. 2) according to religion, there was a statistically significant difference in QOL(F＝2.90, p＜.05). In conclusion, it can be said that social support is an important variable related to QOL in the elderly and that social support levels are higher for the elderly residing at home. Therefore, more specific and objective approaches and efforts are needed to effectively use resources to maintain the elderly at home and to enhance social support available to the elderly in institutions and thereby increase QOL regardless of residence.
