The disease syndrome characterized by the acute vomiting and diarrhea with high mortality had been greatly epidemic in Kyungbuk West Area since March 1990 and it was followed serologically for the classification of the agent. The agent present in feces of dogs associated with this syndrome had characteristic feature in agglutinating pig red blood cells that was specifically inhibited by anti-CPV reference dog serum. This also showed the serological identity with the reference CPV antigen in Hemagglutinating inhibition test. The result obtained were summarized as follows : 1. During 5 years(March. 1990∼September. 1994), 1,470 dogs were investigated on the actual condition of CPV infections. The Infection rate of CPV from dogs was 62.5% and mortality rate was 59.8%. 2. Among 24 fecal samples collected from the dogs with enteric disease, all showed the hemagglutinating activity to porcine erythrocyte ranging from 40 to 5,120 of HA titers. 3. Among 12 sera samples collected from the dogs with enteric disease, all showed the serological identity with the reference CPV antigen from 5 to 5,120 of HI titers. 4. Bacteriologic examination of fecal specimens resulted in the isolation of pathogeric bacteria such as Staphylococcus sp, Streptococcus sp, Escherichia coli and Bacillus. Cultures for salmonella sp and Clostridium remaind negative. 5. The prevalence and identification of internal parasites were determined by fecal examination using the floatation methods. From 20 fecal samples 12(60.0%) were isolated and their species were Toxacara canis, Toxascaris leonina, and coccidium.

The Functional Independence Measure (FIM) is widely used to determine the dependency of activity of daily living in rehabilitation patients. The purposes of this study were to evaluate the unidimentionality of the FIM physical items and to analyze the validity of cross-functional levels in stroke survivors in Korea. Thirteen physical items of FIM were rated according to an ordinal scale of a 7-level classification. Two hundred and seventy-nine patients participated in the study (age range 18~92 years and 57% male). Six items-eating, bladder control, bowel control, transfer to and from the bed/wheelchair, transfer to and from the toilet, and bathing-showed misfits with the Rasch model. The most difficult item was 'bathing', the easiest item was 'bowel control'. Although there were several differences within functional levels, the hierarchical order of item measures was rather similar. 'Bathing' was the most difficult in high level patients (above 60), however 'stairs' was most difficult in the middle level (41~60) group. In the low level group (below 40), 'toileting' was the most difficult. In conclusion, the present study has shown several differences of item difficulty among functional levels. This result will be useful in planning interventions, and developing rehabilitation programs for stroke survivors.

In this study, various damage modes in bending unimorph piezoelectric composite actuators with a thin sandwiched PZT plate during bending fracture tests have been evaluated by monitoring acoustic emission (AE) signals in terms of waveform and peak frequency as well as AE parameters. Three kinds of actuator specimens consisting of woven fabric fiber skin layers and a PZT ceramic core layer are loaded with a roller and an AE activity from the specimen is monitored during the entire loading using an AE transducer mounted on the specimen. AE characteristics from a monolithic PZT ceramic with a thickness of $250{\mu}m$ are examined first in order to distinguish different AE signals from various possible damage modes in piezoelectric composite actuators. Post-failure observations and stress analyses in the respective layers of the specimens are conducted to identify particular features in the acoustic emission signal that correspond to specific types of damage modes. As a result, the signal classification based on waveform and peak frequency analyses successfully describes the failure process of the bending piezoelectric composite actuator exhibiting diverse failure mechanisms. Furthermore, it is elucidated that when the PZT ceramic embedded actuators are loaded mechanical bending loads, the failure process of actuator specimens with different lay-up configurations is almost same irrespective of their lay-up configurations.

The subject of externality of agricultural water supply has been discussed in the OECD AC ( Organization for Economic Cooperation and Development Agriculture Committee) while argued between monsoon Asian developing countries and the agricultural product export nations (Australia, EU, etc). It argued that a 'positive' approach to multifunctionality views agriculture as an economic activity with multiple, interconnected outputs or effects, and a 'normative' approach interprets multifunctionality in terms of the multiple roles assigned to agriculture. and the agricultural product export nations insisted 'negative' approach to externality of agricultural water supply like causing water pollution. So, in this study, define the externalities (positive, negative and economic, environmental) in terms of the agricultural water supply and calculate benefit and cost each the externalities by cost estimation. As results, BC is calculated to 1.28 which means that it is more economical to agricultural water supply and shows that although the negative exernalities comes out while supply the agricultural water, it still more valuable to supply the agricultural water.

PURPOSE: This study examined the differences between male and female workers by investigating the various factors that affected the workers' abilities to return to work according to the International Classification of Functioning standards. METHODS: We analyzed the personal factor, environmental factor, work performance and participation factor related to ICF according to worker's gender. For this purpose data from the third Worker's Compensation Insurance panel survey conducted by the Korea Workers' Compensation & Welfare Service were analyzed. In order to verify the research model, we used frequency analysis, cross analysis to compare the differences between male and female workers according to personal, environmental, work performance, and participation factors and hierarchical regression analysis to identify significant factors affecting job performance. RESULTS: The results, indicate that the level of education, license status, working period, socioeconomic status and employment type of female workers were lower than those of male workers. Factors that have the greatest influence on job performance are grade of disability, status of disability, economic activity status, and instrumental activities of daily living (p<.05). CONCLUSION: It is necessary to provide socially stable employment support and social policy support without discrimination to allow disabled female workers to return to work and maintain their jobs and to study factors influencing job performance further.

In this study, the marker compound contents of both the taproot and lateral root of Danshen (Salvia miltiorrhiza Radix), which is cultivated in Korea, were investigated. The salvianolic acid B content was the highest in the taproot (5.17-6.75%) and lateral root (3.99-5.69%). The cryptotanshinone, tanshinone I, and tanshinone IIA contents were higher in the lateral root than in the taproot of Danshen (p <0.05). Principal component analysis results revealed that the taproot was correlated to the salvianic acid A, rosmarinic acid, salvianolic acid B, and salvianolic acid A contents, whereas the lateral root was correlated to the cryptotanshinone, tanshinone I, and tanshinone IIA contents. The total phenolic content and total flavonoid content of the taproot were higher than those of the lateral root (p <0.05); however, the antioxidant activities of the taproot and lateral root of Danshen were similar. The salvianolic acid B content was correlated to the TPC of the taproot (r=0.748) and the 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid radical scavenging activity of the lateral root (r=0.847). This study could provide useful information for the classification of Danshen as a herbal medicinal product.

This paper is to focus the financial ratio analysis of the Korean textile and apparel companies due to fast changing domestic industry. Financial ratios are playing a pivotal role in management analysis to assess the present conditions to predict the future. Subjects are belonging to textile and apparel manufacturers based on Firm Classification Standard while registered as securities listed-firms or Kosdaq-listed firms under the Electronic Notification System of Korean Banking Supervisory Authority. 41 companies' data have been analyzed including 17 apparel companies and 24 textile companies. 14 representative financial ratios are analyzed. In this paper, financial ratios can be classified into four categories as follows: stability ratios, profitability ratios, growth ratios and activity ratios. The independent t-test was performed using SPSS 18 for a 10 year simple arithmetic average. The following conclusion has reached regarding aspects of management conditions and performances. When compared the ratios indicating stability, textile and apparel companies did not show much difference in debt ratio and the ratio of earning to interests. However, when compared the profitability ratios measuring the ability to produce incomes, apparel companies showed higher ratios than textile companies. Thus it is important to recognize financial characteristics of each industry.

This study is a qualitative case study aiming at understanding and finding out influential factors and barriers when school teachers choose Environmental Education as their Creative Discretionary Activities. To do this, this study focuses on the process of two teachers' choices of the Creative Discretionary Activities in two other elementary schools. The results of this research are follows. Two teachers' choices are affected by several influential factors, divided into external factors and internal factors. External influential factors include culture of school and education, media, chief education officers, parents and school. Internal influential factors are teachers' value and philosophy of education, teachers' experiences, teachers' capacity. These influential factors' forces aren't the same with each other. These influential factors, are influenced by educational, social, national, local, and school level indicated by Taylor et al's (1974) classification criterion. Especially, however, Korea's particular educational environment focusing on university entrance examination strongly affects teachers' choice. School factors also has a big strong effect on teachers' choice. Among others internal actors are the most serious influential factor affecting on teachers' choice.
