This study was conducted to expand the use of the Gal Ot which has been called Cheju-Do's folk costume. The Gal-Ot has been mainly used the traditional clothes which the farmers have worn during working in the fields. In this study, We firstly developed the dyeing methods used the immature persimmon juice and dyed the dress and fabrics. We secondly designed the diverse Gal-Ot which we can wear for the everyday dress, that is, men's and women's upper and lower clothes and reformed another Korean Style's Dresses and children's one-piece. This study strongly suggested that the Gal-Ot would be used for the everyday wear and the street wear for adults and children and that the improvement of dyeing method used the immature persimmon would be expanded the use of the Gal Fabrics.

Principal component analysis (PCA) was used to improve image classification by the unsupervised classification techniques, the K-means. To do this, I selected a Landsat TM scene of Jeju Island, Korea and proposed two methods for PCA： unstandardized PCA (UPCA) and standardized PCA (SPCA). The estimated accuracy of the image classification of Jeju area was computed by error matrix. The error matrix was derived from three unsupervised classification methods. Error matrices indicated that classifications done on the first three principal components for UPCA and SPCA of the scene were more accurate than those done on the seven bands of TM data and that also the results of UPCA and SPCA were better than those of the raw Landsat TM data. The classification of TM data by the K-means algorithm was particularly poor at distinguishing different land covers on the island. From the classification results, we also found that the principal component based classifications had characteristics independent of the unsupervised techniques (numerical algorithms) while the TM data based classifications were very dependent upon the techniques. This means that PCA data has uniform characteristics for image classification that are less affected by choice of classification scheme. In the results, we also found that UPCA results are better than SPCA since UPCA has wider range of digital number of an image.

Where people within a certain cultural sphere have formed their own peculiar cultural beliefs including health belief, health value and health practice, care-givers have a good understanding of health management as those practices exist in the client's sociocultural background. The purpose of this study was to describe various caring behaviors in traditional childbearing management and ultimately to provide basic data for nursing practice and sustantive maternity nursing theory. To investigated taring behaviors, the ethnographic approaches were used. The fieldwork for this study has been conducted from December, 1991 to September, 1992. The data collection method was used in-depth interview. The key informants were 19 womans aged from 60 to 84, and general Informant was a native aged 50. Results of the study were as follows. The components of caring behavior inculded heeding, preventing from impurities, encouraging the power, praying, warming up one's body, enduring, helping, healing, resting, making preparations, utilizing mugwort, creating good blood circulation, tabooing, This components of taring behavior were 6 categories, making every effort, encouraing, contriving an easy labor, healing, making preparations, enduring, The prominent caring beehavier during childbearing process was making every effort. In conclusion, for more effective childbearing management of care-givers must eliminate from their own minds 'primitive' or 'supertitious' attitudes toward traditional childbearing management. Also it is desirable that they establish Korean style nursing intervention along with modern scientific practices in conjunction with the traditional childbearing management.

Plagiorchis muris has been found in both been found in both house and field rats as well as in humans. The infection status of th second intermediate hosts of P.muris is prerequisite in understanding their biological features in an ecosystem. Six species of dragonflies were caught in a wide range of areas in Korea;and they were Sympertrum darwinianum, S.eroticum, S. pedomontanum, S. infuscatum, Pantala flavoscens, Caloteryx atrata, and Othertrum albistylum speciosum. The occurrence of P. muris metacercariae in dragonflies was nationwide with various infection rates. The metacercarial burden of P. muris in the surveyed areas was the highest in S. eroticum followed by S. darwinianum, S. pedomontanum, and C. atrata. The highest infection rate by P. muris metacercariae was found in S. darwinianum followed by S. eroticum. The metacercarial buredn was particularly heavy in the dragonflies found in Hamyang-gun and Kosong-gun, Kyongsangnam-do. It is, therefore, likely that dragonflies play a significant role as the second intermediate hose in the life cycle of P. muris in Korea.

For rebuilding and managing fish stocks and fisheries, the biological and socioeconomic evaluations on fisheries management regulations are important. This study aimed to estimate the economic effectiveness of different mesh sizes in the yellow croaker gillnet fishery. In particular, by comparing economic effects of mesh sizes, 50mm and 52mm, it aimed to provide the economic validity for increasing mesh sizes. Analytical results showed that the fishing revenue was higher in the vessels using a mesh size over 52mm than that in the vessels using a mesh size less than 50mm. In addition, the effect of fishing cost reduction was also larger in the vessels using a mesh size over 52mm than that in the vessels using a mesh size less than 50mm.

Generally known psittacosis or ornithosis is a disease of birds caused by the bacterium Chlamydia psittaci. Humans are accidential hosts and are most commonly infected from avian sources. It raises hepatitis or neurosis. As major outer membrane protein (MOMP) of Chlamydia psittaci has been known to play a role in the avoidance of host immune defenses, research on developing a Chlamydia vaccine has focused on the MOMP. In this study, the gene encoding the major outer membrane protein (MOMP) of the Chlamydia psittaci strain 6BC was cloned and expressed in Escherichia coli strain M-15. The recombinant DNA was cloned by fusion prokaryotic expression vector pQE30-GFPII. Expression of the recombinant protein was performed in E. coli and was induced by IPTG. The size of expressed recombinant protein is 74.220 kDa (MOMP, 43.260 kDa; GFP expression region, 30 kDa; $6{\times}His$ tag, 960Da). This protein was purified by using his-tagging-inclusion body. Recombinant protein was reconfirmed through ELISA test and western blot with antibody against pQE30-GFPII. It will be useful antibody development.

This study is designed to positively transform a teacher's emotional state whilst teaching their classes and be able to create happier lessons for preschool children. To do this, a teacher needs to reflect upon current problems and take steps to deal with them. The data for this study was collected from participatory observation and in-depth interviews, making use of photos, a reflective teacher's journal and interview records from Mar. 28, 2011 through Oct. 7, 2011. The problems identified were, (1) teacher centered classes, (2) a daily routine filled with large group activities, (3) disruptive students, and (4) repetitiveness. The routes to greater classroom "happiness" are (1) rearranging seats, (2) "story sharing activities" in small groups, (3) making a separate "story sharing activity" area, (4) using small groups instead of large groups, (5) changing the daily routine. The role of the teacher in finding greater "happiness" are (1) meaningful, 'real observation', (2) discovering genuine change from small points, (3) power sharing, and (4) growing and developing with children.

Power systems must be operated within limits that will ensure adequate generation and transmission capacity to avoid cascading. In developing a set of operations limits, it is important to do so within a general framework in order to ensure that the operating objectives are met. In the this regard, when the system experiences a generation-load imbalance, the principles of sound operation will be maintained by bringing under control an unscheduled power flow condition as quickly as possible. This paper presents load shedding application which responds both to frequency and to rate of change of frequency. Its application is in the operating situation of load suddenly in excess of generation, either because of generator or other equipment failure. A scheme which is able to utilize rate of change of frequency as well as frequency itself is an improvement over existing scheme.

Purpose: This study was to identify factors affecting regular mammography screening behavior of outpatients. The target subjects were 150 women who had visited the breast clinic at the university hospital, and the study period was around 10 months from March to December 2006. Data were analyzed by using $\chi^2$-test, t-test and logistic regression analysis. Results: Of the subjects, 50% experienced mammography and 31.6% took mammography regularly. In the relational analysis between various factors and regular mammography, there were significant differences among the $41{\sim}50$ year old group, the employed group, the high income group, the regular exercise group, the non-drinking group, and the previously x-rayed group. And, in the Logistic Regression analysis, those who preferred bean food were 3.20 times more likely to take mammogram regularly, and those who married were 3.49 times more likely to do than the unmarried. Also, those who had low health belief and who were under age 51 were less likely to take regular mammogram. Conclusion: In order to increase the rate of conducting regular mammography, there must be different intervention strategies according to food habit, marital status and age, and a support system must be devised to increase health belief about breast cancer.

Muscular lesion was detected in a 23-month-old castrated bull encountered at Kyungsan slaughter house. The lesion appeared as fat intervening muscle fibers. The affected animal had no clinical signs. On microscopic examination, there was replacement of many muscle fibers by normal fat cells. Numerous fat cells were located between muscle fibers. Remaining skeletal muscle cells were in degenerative process, and thus abnormal skeletal muscle cells had loose fibers while normal had intact ones. The advent of inflammatory cells is not at the lesion, which is unique view in steatosis.
