In order to provide information for the establishment and maintenance of a rehabilitation day care center for stroke patients. this study is to assess needs for the rehabilitation day care center of the stroke patients and to identify the factors influencing the needs for the center. The data were collected face-to-face interview with 223 stroke patients. using a structured questionnaire. from September 24. 2001 to November 20. 2001. Major findings are as follows. 1. Most of the participants($94.6\%$) needed rehabilitation day care center for stroke patients. $95.5\%$ of participants were willing to use the rehabilitation day care center. 2. Also the score of the needs for the center's health services was $2.84\pm60$ out of 4.00. In regards to the sub-contents. while the physical exercise therapy showed the highest mark($3.54\pm71$) in the needs. the following marks showed physical therapy($3.48\pm79$), training for the memory. thinking and judgment($3.30\pm93$). training for ADL($3.09\pm99$). health education program($3.04\pm93$). In the meantime. the expected effects from the use of the center are $2.89\pm61$ out of 4 and its sub-contents showed that the center would promote their physical and mental well-being($3.30\pm74$) and the center would be more effective than in home care($3.12\pm70$). 3. Meanwhile. the desired frequency of use in the future and distance had significant interrelation with their families living together(p<.05). In addition those who paid to use it differentiated significantly according to their ages and the types of insurance they had(p<.05). 4. The needs in degrees of speech disorder therapy and hobbies & amusements. the patients with other disease had significantly higher degrees than those patients without it (p<.05). Also in regard to the need degrees for physical therapy. healthy education programs and individual counseling including their families. the degrees of the patients with speech disorders were significantly lower than those of the patients without the disorder (p<.05). On the other hand. the patients with speech disorders were significantly higher than those patients without it in the need degree of the speech disorder therapy (p=.000). And the needs in degree concerning about speech disorder therapy. physical exercise therapy. training for ADL. medicinal substances therapy and family education were negatively correlated with the ADL (r=-.236$\sim$.305, (p<.005). 5. Finally. the expected effect of using the rehabilitation day care center showed significant differences statistically according to whether or not they had other disease (p<.05). In conclusion. the study showed the stroke patients were willing to use the center and had a high requirements for it and they especially had relatively high need degrees for the physical exercise therapy. physical therapy. training for memory. thinking and judgment. and healthy education program. And significant factors for the use of the center were their ages. types of insurance. family cohabitation. complications and speech disorders. ADL and so forth. Accordingly. the rehabilitation day care center needs to be established for the stroke patients and the center should develop rehabilitation care programs. which are individual and special programs customized for each patient's characteristics and health conditions.

The present study was conducted to investigate the effect of dietary grape pomace on lipid metabolism and hepatic morphology of rats fed a high fat diet. The high fat diet contained additional 15% lard to AIN 93-based diet. Male Sprague-Dawley rats were fed experimental diets containing 5% grape pomace for 4 weeks. Serum activities of glutamic-oxaloacetic transaminase (GOT) and glutamic-pyruvic transaminase (GPT) were not changed by high fat and grape pomace feeding. Serum concentration of triglyceride in rats fed a high fat diet was decreased significantly by dietary grape pomace. Hepatic concentrations of total lipid, total cholesterol and triglyceride were reduced in grape pomace groups with a high fat diet. Fecal concentrations of total cholesterol and triglyceride were increased in grape pomace groups with a high fat diet. The fecal content of coprostanol was not different among the groups. Dietary grape pomace increased the fecal excretion of cholesterol and coprostanone in rats fed a high fat diet. The fecal excretion of bile acid was not affected by feeding grape pomace in rats fed a high fat diet. Light micrographs of liver tissue revealed lipid droplets were increased by a high fat diet, but dietary supplementation of grape pomace tended to alleviate such changes.

Pesticide residue in the eggs in the market has become a significant problem in Korea. In particular, the detection of fipronil indicated that unregulated pesticide residue can be present in livestock products, including eggs. Institutionally unregulated pesticides are a risk to human health and the ecosystem. In this study, we analyzed the system of agricultural pesticide management in Korea, the European Union, and the United States of America (USA) and discussed the problems of the Korean management system and the possible improvement directions. Based on the analysis, we considered three tasks: registration of pesticides, pesticide residue levels in food, and pesticide residue levels in environmental media. The registration of pesticides was conducted by the Ministry of Agriculture, Food, and Rural Affairs in Korea; the Directorate-General for Health and Food Safety in the European Commission (EC); and the US Environmental Protection Agency (USEPA) in the USA. The work regarding pesticide residue levels in food was conducted by the Ministry of Food and Drug Safety in Korea, the Directorate-General for the Health and Food Safety in the EC, and the USEPA and Food and Drug Administration in the USA. The work regarding pesticide residue levels in environmental media was conducted by the Ministry of Environment in Korea, the Directorate-General for Environment in the EC, and the USEPA in the USA. Therefore, Korea should review the extension of pesticide residue standards in the environmental media for strengthening the system of management of unregulated agricultural pesticides.

Purpose : A new airway inflammatory marker, exhaled nitric oxide(ENO) has been reported to correlate with bronchial hyperresponsiveness(BHR) and atopy. The purpose of this study was to analyze the relationship of ENO with BHR or atopy in patients with asthma and with allergic rhinitis. Methods : The subjects consisted of 55 children with asthma, 17 with allergic rhinitis, and 14 healthy controls. The asthma group was subdivided into the atopic asthma group(n=37) and the nonatopic asthma group(n=18) and the allergic rhinitis group into BHR group(n=7) and non-BHR group(n=10). All were investigated with spirometry and measurements of ENO concentration. The correlations between ENO concentration and both methacholine $PC_{20}$(provocative concentration causing a 20% decrease in forced expiratory volume in one second) and the number of allergen skin test positivity were analyzed. Results : ENO concentrations of both asthma and allergic rhinitis groups were significantly greater than that of control(P<0.01). ENO concentration of atopic asthma was significantly greater than that of nonatopic asthma(P<0.01). In allergic rhinitis, ENO concentration did not differ according to the presence or absence of BHR(P=0.50). ENO concentrations correlated significantly with the number of skin test positivity(r=0.32, P=0.02) or methacholine $PC_{20}$(r=-0.38, P<0.01) in asthma group, but not in the allergic rhinitis group(r=0.42, P=0.09; r=-0.06, P=0.83). Conclusion : In asthma patients, some pathogenetic mechanisms associated with atopy and BHR seem to influence ENO concentration. In allergic rhinitis patients, some factors other than BHR may be important in determining ENO concentration.

The data were analyzed by using an S. P. S. S. computerized program for mean, standard deviation, percentage and paired t-test. The results of this study were as follows: 1. The increase in $PaO_2$ after hyperoxygenation and hyperinflation was highly statistically significant(p=0.041), and the increase in $PaO_2$ immediately after suctioning was not significant (p=0.752). The time of lowest $PaO_2$ was 30 seconds after the endotracheal suction. 2. The occurrance of cardiac arrhythmia after the endotracheal suction included sinus tachycardia, sinus arrhythmia, sinus bradycardia, premature atrial contraction (PAC), and premature ventricular contraction (PVC). The most frequent cardiac arrhythmia was sinus tachycardia (a subjects). Sinus arrhythmia was observed in 5 subjects and continued till 10 minutes after suctioning in two of these. Sinus bradycardia occurred in only 3 subjects and among them, 1 subjects shows sinus arrythmia till 10 minutes after suctioning along. PAC was observed in only one subject and continued till five minutes after suctining along with sinus arrhythmia. PVC was observed in three subjects: it lasted for only 30 seconds after suctioning in two subjects. but continued for 10 minutes after suctioning in the third. 6 subjects manifested two kinds of Cardiac arrhythmia Three of them showed sinus tachycardia with PVC, another 2 showed sinus bradycardia with sinus arrhythmia, and the other subject showed sinus arrhythmia with PAC. 3. The increases in heart rate during the endotracheal suction immediately after and at 30 seconds after suctioning were statistically significant (p=0.005). The increase in heart rate at one minute after suctioning was also significant (p=0.023). The increase in heart rate continued until 10 minutes after the endotracheal suction, but was not statistically significant In this study, endotracheal suctioning with hyperoxygenation and hyperinflation was effective in preventing a decrease in $PaO_2$ after suctioning, but not in preventing cardiac arrhythmias. Nurses should be aware of the complications of endotracheal suctioning and do effective hyperoxygenation and hyperinflation before and after suctioning. Further research is needed to develop a efficient endotracheal suction method which will minimize complications. This study needs to be replicated with different population of patients intubatted or having a tracheostomy, specifically, patients who cardiac or pulmonary desease.

In order to develop liquid fertilizer using rendering by-product, rates and velocities of degradation from rendering by-product using pig cadaver investigated under different amount of injection and time with degradation agents (KOH, NaOH, $HNO_3$ and $H_2SO_4$). The amount of residue by degradation agent of $HNO_3$ treatment method was higher than that in KOH, NaOH and $H_2SO_4$ treatment methods. The degradation velocities (K; $hr^{-1}$) of rendering by-product in KOH treatment method were higher in the order of 25% ($0.0309hr^{-1}$) > 30% ($0.0268hr^{-1}$) > 20% ($0.0142hr^{-1}$) > 15% ($0.0111hr^{-1}$) > 10% ($0.0102hr^{-1}$) of weight of rendering by-product. In all conditions, the degradation velocity of rendering by-product using $H_2SO_4$ 30% of weight of rendering by-product was rapid than that for KOH, NaOH and $HNO_3$ treatment methods. Degradation rates of rendering by-product using NaOH were similar to that of KOH and $H_2SO_4$ except for $HNO_3$ under injecting 25% and 30% of rendering by-product weight.

This study investigated the possibility of usage of freeze-dried ingredients for the preparation of Nabak kimchi. The quality characteristics of Nabak kimchi using freeze-dried ingredients (radish, kimchi cabbage, green onion, garlic and ginger) were monitored during storage at $4^{\circ}C$. The initial pH of Nabak kimchi was 5.76~5.93, however, it decreased significantly over increasing storage periods (p<0.05). The titratable acidity of Nabak kimchi increased during storage, reaching 0.43~1.08%. Among the freeze-dried samples, those treated with freeze-dried radish and minor ingredients showed lower titratable acidity than that of the control. The initial number of total aerobic and lactic acid bacteria were 5.57~6.25, and 5.52~6.24 log CFU/g, respectively. After 28 days, the population of total aerobic and lactic acid bacteria in the raw ingredients and freeze-dried minor ingredients was less than 8.0 log CFU/g, but more than 9.0 log CFU/g in other samples. Yeasts and molds in Nabak kimchi were detected up to 2~3 log CFU/g, but coliforms were not detected in all samples during storage. The score of firmness and overall acceptability in the control, raw ingredients and freeze-dried minor ingredients were significantly higher than others (p<0.05). These results indicated that freeze-dried ingredients, such as green onion, garlic, and ginger, can be used in kimchi and would delay microbial growth and extend the shelf-life of kimchi without any deduction of sensory quality.

CISG Article 71 (1) states that a party may suspend the performance of his obligations if, after the conclusion of the contract, it becomes apparent that the other party will net perform a substantial part of his obligations as a result of a serious deficiency in his ability to perform or in his creditworthiness or his conduct in preparing to perform or in perfoming the contract. CISG Article 71 (2) states a 'right of stoppage in transit' that if the seller has already dispatched the goods before the grounds described in the preceding paragraph become evident, he may prevent the handing over of the goods to the buyer even though the buyer holds a document which entitles him to obtain them. The present paragraph relates only to the rights in the goods as between the buyer and the seller. Under the right of stoppage in transit, the carrier copes with risks that the seller may claim damages arose from the handing over the goods, if he hand over the goods to the buyer and that the buyer may claim damages, if he deny handing over the goods to the buyer who has the document which entitles him to obtain the goods. Therefore the legal position of the carrier may become weak. This paper purpose to point out the legal weakness of the carrier under the right of stoppage in transit and to provide the proper legal act of the carrier and possible practice related to various characters of the contract of sale of the goods. Although there is the opinion it prevent from handing over the goods to the buyer actually under the interpretation that the buyer should take claim damages to the seller, if the goods are handed over to the buyer under the right of stoppage in transit, it is not appropriate because the opinion may disable the right of stoppage in transit. The right of stoppage in transit could be carried out under any payment conditions except letter of credit and under any mode of transportation except the cases that carrier is the buyer himself or the agent of the buyer. It could be executed regardless the forms of the transport document.

The purpose of this study was to invent anger-inducing automatic thoughts examination for elementary school children based on its investigation for Korean one. I made the anger-inducing Automatic Thoughts Questionnaire(I, II) and made an examination of the contents of the automatic thoughts with it. Based on it, with preliminary questionnaire 90, I did principal component analysis varimax rotation and then final anger-inducting automatic thoughts examination of 40 question in 2 primary factor construction was consisted. I made 300 students carry out it to know its reliability, propriety and made 100 students carry it out at 2-week intervals test-retest. I divided them in three groups as low, middle and high according to its soore regarding anger-inducting automatic thoughts, I confirmed the variation of each group in positive thoughts, self-esteem, life satisfaction, anger, the result is same as follows; First, the content of Anger-inducting Automatic thoughts for elementary school students is revealed as unreasonableness(56.4%), retailation and passive, active offense(16.3%), blame and contempt(11.9%), injured pride and refusal(9.2%), absurd(3.9%), abandonment and avoidance(2.1%), self-abasement in turn. Second, said inventory is consist of 2 notion; first(20 questions) is blame, retaliation and second(20 questions) is injustice. Inner-item consistency of total 40 question is .97, Split-half reliability is .93, Test-retest reliability is .86. Third, criterion validity is revealed fine by reviewing the correlation between existing index related to the inventory of Anger-inducting Automatic thoughts of the elementary school students. Moreover, to find out discriminant validity, I divided three classes(low, middle, high) according to the score of said thoughts. As a result, there is certain variations when I confirmed variations in groups by reviewing the self-esteem, positive way of thinking, life satisfaction, anger.

Purpose : Multidrug-resistant tuberculosis (MDR-TB) is an emerging threat to human beings. However, there is little data on the current status of MDR-TB in Korea. This study investigated the current status of MDR-TB in Korea using a survey of all the data from drug susceptibility tests (DST) performed across the country over the last three years. Method : The DST results between Jan. 2000 and Dec. 2002 from 7 laboratories, which were in charge of all antituberculous DSTs across the country as of March 2002, were collected and analyzed to determine the actual number of drug-resistant or MDR-TB patients, annual trend, degree and pattern of resistance against anti-TB drugs, etc. Results : Six laboratories used the absolute concentration method for DST and one used the proportional method. 59, 940 tests had been performed over the 3 year study period. The number of DST performed annually was 18,071, 19,950, and 21,919 in 2000-2002, respectively. The number of resistant tuberculosis patients (resistant against at least one anti-TB drug) had increased by 16.9% from 6,338 in 2000 to 7,409 in 2002. The rate of resistant tuberculosis among all DST results was 35.1% in 2000, 34.5% in 2001, and 33.8% in 2002. The number of MDR-TB patients (resistant against at least both isoniazid and rifampin) showed an increasing trend (14.5%) from 3,708 in 2000 to 4,245 in 2002. Conclusion : Approximately 4,000 MDR-TB cases are newly identified by DST annually and the number is showing an increasing trend. This study suggests that in order to cope with the current MDR-TB situation, the DST methods will need to be standardized and more aggressive measures will be required.
