To utilize oyster cannery processing waste water effectively, this study was carried out to prepare instant powdered soup using oyster wash water. Instant powdered soup from oyster hot-water extracts (HWE) was prepared by mixing oyster spray-dried hot-water extracts (15 g) with table salt (5 g), cream powder (19 g), milk replacer (12 g), wheat flour (20 g), corn flour (15 g), starch (5 g), glucose (7.5 g) and onion powder (1.5 g). In preparing instant powdered soup from oyster wash water (OWW), powder from oyster spray-dried wash water instead of the spray-dried hot water extracts, was added and other additives were added in proportion to those in the HWE. The OWW consists mainly of carbohydrates (71.1%). It was not different from the instant powdered soup from hot-water extracts. The volatile basic nitrogen, vaible cell counts, coliform group of instant powdered soup from oyster wash water contains 29.4 mg/100g, $4.6{\times}10^4\;CFU/g$, <18 MPN/100g, respectively and its water activity has 0.246. So it was a hygienically safe and conservable instant food. The main fatty acid of OWW was 16 : 0 and 18 : 1n-9. Its chemical score of protein was 59.4% and its main inorganic matter was iron. According to a sensory evaluation, in contrast to the HWE, the OWW had a slightly lower aroma but better taste. It was concluded from the above chemical and sensual evaluation that the oyster wash water can be used as a flavor enhancer for instant powdered soup.

Objectives : The purpose of this study is to report the effectiveness of Korean medical treatment on 222 patients with alopecia areata. Methods : The subjects of this study were 222 patients who had received Korean medical treatment among the patients who visited the Balmer's Korean Medicine Clinic from January 1, 2016 to December 31, 2017. The extent of the alopecia areata was measured every month to determine the improvement. We analyzed the relationship between the types of alopecia areata, the extent of hair loss, duration of illness, age at first visit, and the treatment of alopecia areata. Results : 1. There were 100 males(45.0%) and 122 females(55.0%). The mean age of patients was 35.3 years old. 2. Of the 222 patients, 142(64%) were "cured". 31(14%) showed "good", 21(9.5%) showed "fair", 28(12.6%) showed "poor" improvement. 3. According to clinical records, of the 64 patients with alopecia areata(AA), 48(75.0%) were cured. Of the 100 patients with alopecia areata multiplex(AAM), 68 patients (68.0%), 12(50.0%) out of 24 patients with ophiasis, 5(55.6%) out of 9 with alopecia semi-totalis(AST), 3(50.0%) out of 6 patients with alopecia totalis(AT), 6(31.6%) out of 19 patients with alopecia universalis(AU) were cured. 4. Patients with the wider hair loss extent and with more severe type of alopecia areata required longer treatment period to cure, and the cure rate was lowered(p<0.05). 5. The shorter duration of the disease was related to the higher cure rate(p<0.05). If the treatment was started after six months of the duration, the cure rate was lowered. Therefore, beginning treatment within six months of the onset is recommended. 6. The period until terminal hair showed was 1.5 months for AA, 1.7 months for AAM, 1.6 months for ophiasis, 1.9 months for AST, 2.3 months for AT, 3.2 months for AU. 7. The treatment period to cure was 4.9 months for AA, 7.3 months for AAM, 7.7 months for ophiasis, 6.8 months for AST, 7.7 months for AT, 16.3 months for AU. 8. The major prognostic factors were extent and type of alopecia, duration of the disease and relapse. Conclusions : We analyzed the effectiveness of Korean medical treatment through cure rate according to the prognostic factors. This study will provide useful data for the treatment of alopecia areata.

Changes in quality properties of Kochujang prepared with Paecilomyces japonica powder and extract using different solvents were investigated during 90 days of fermentation at $20^{\circ}C$. Although moisture contents were not significantly different, pH of P. japonica-added Kochujang was lower than that of control group without P. japonica, and decreased with increasing fermentation time. Amino nitrogen content increased up to 60 days of fermentation and decreased slightly after 90 days, with that of P. japonica-added Kochujang showing highest on 30 and 60 days at 179.2 and 282.2 mg%, respectively, higher than control gruup. L, a, and b values decreased in proportion to fermentation period, with P. japonica-added Kochujang, particularly P. japonica powder-added Kochujang, lower than those of control g개up. Sensory evaluation test showed color of control group was 'clear red', whereas that of P. japonica powder-added Kochujang was 'dark reddish brown' and P. japonica extract-added Kochujang was darker than control group; consumer preference for dark color was low, Textures of all samples were 'glossy and smooth', showing high consumer preference. Salt content of P. japonica-added Kochujang was higher than that of control group, with P. japonica extract-added Kochujang higher than that made with powder Hot taste or P. japonica-added Kochujang was weaker, whereas its flavor higher, than control group, with P. japonica powder-added Kochujang showing highest flavor score. Overall preference was higher for P. japonica-added Kochujang than control group, with P. japonica water extract-added Kochujang showing the highest score.

Objectives: This study was to evaluate the compliance of hypertensive patients and its related factors registered at Community Health Practitioner Post(CHCP). Methods: 304 patients were interviewed by trained nursing students during one month(June~July 2004). The questionnaire included general charactristics, knowledge of hypertension, health education experience, constructs of Health Belief Model, self efficacy and so on. Compliance group was defined "having regularly medication and good life style". Good life style included regular exercise, non-smoking, little alcohol, low salt diet, weight control. Results: In compliance group 90.3% of man and 93.3% of woman were regularly taking hypertensive medicine, and 45.2% of man and 56.4% of woman were having good life style (compliance group). In both man and woman, the group of higher education were more compliance group, but were statistically significant were in man(p<0.05). In woman, the compliance group have significantly higher score in knowledge of hypertension(p(0.05). The compliance group have significantly higher self-efficacy score in both man and woman (p<0.05). In Health Belief Model, susceptibility and benefit were statistically significant in man, seriousness, benefit and barrier in woman(p<0.05). In multiple logistic regression analysis, education level and self efficacy in man and knowledge of hypertension, self-efficacy and benefit in woman were significant variables (p<0.05). Conclusions: It is very important to evaluate and modify life-style adding to having regularly medication in hypertensive patients registered at CHCP. To this, health education programs about benefit to compliance and the methods to improve self-efficacy should be developed for this patients.

This study aimed for exploring the best recipe of Sangjabyung to increase its utility value and to develop traditional Korean rice cake industry for next generation. The best recipe was determined after several tests such as sensory evaluation and mechanical measurements for texture, moisture content, and colorimetry. The samples prepared with 5% of acorn starch with honey showed the best scores in sensory evaluation for color and flavor, 5% of acorn powder with sugar for grain, 15% of acorn powder with sugar for moistness and chewiness, 15% of starch with honey for sweetness, and non-glutinous rice flour mixed with 10% of acorn powder and sugar for overall quality. Every item except for flavor was significantly different from that of control (P<0.05). The highest score for springiness was obtained from the samples prepared with 10% of acorn starch with sugar, cohesiveness with 5% of acorn starch with sugar, chewiness with 15% of acorn starch with honey, gumminess with 15% of acorn starch with honey, adhesiveness with 5% of acorn starch with honey, and hardness with 15% of acorn starch with honey. All items were significantly different from that of control (P<0.05). The overall quality of sensory evaluation was correlated with moistness(P<0.05), springiness, cohesiveness(P<0.01), and adhesiveness(P<0.01) in mechanical test. Moisture contents of rice flour, acorn starch, and acorn powder were 32.93%, 8.52%, and 13.26%, respectively. The desirable moisture content in Sangiabyung was 44.11% in the case of using rice flour with acorn starch or 44.33% for rice flour with acorn powder. As a result of colorimetry, the best L, a, and b values were obtained from the rice cakes with 5% acorn starch and oligosaccharides, with 15% of acorn powder and sugar, and with 15% of acorn starch with oligosaccharides, respectively. Overall. the most desirable recipe for Sangjabyung was determined as rice flour 315 g, acorn starch or acorn powder 35 g, sugar 60 g, salt 3.5 g, and water 130 ml.

Successful weaning is very important to provide adequate nutrients for normal growth and to induce a good diet habit. We conducted a survey on the knowledge and attitudes of women who live in Taegu toward weaning in infants, to figure out how much they know about weaning diet for the infants, which source they prefer to get the information about weaning diet, whether their knowledge affect their practice about weaning in infants, and the most effective way to educate them. A survey was conducted with the prepared questionnaire on women who responded at the residential area and market place, and those who visited Department of Pediatrics, Yeungnam University Hospital from July 25 to September 15, 1997. Statistical analysis was done with student t-test and ANOVA using SPSS program. Among total 303 responders, those who aged between 30 and 39 years were 37.2%. Scores for the six questions about weaning policy showed highest in the age group between 30 and 39 years. Higher score was recorded in the more educated group, in those who get informations about weaning diet from books, magazines and pediatricians. The majority of the responders had wrong concepts, such as feeding weaning diet using bottle(69.1%), feeding mixed with formula in the same bottle(64.5%), addition of salt(68.4%). Those who had higher educational level preferred books, magazines rather than neighbors or mother to get informations about weaning diet. Those who preferred books or magazines started weaning, stopped bottle feeding, and used spoon earlier, and their children had unbalanced diet habits less frequently. Home-made food was used most frequently, and commercial products were used less frequently. Those who were employed preferred home-made food rather than commercial products, it may be caused by the difference of the educational backgrounds from those of the unemployed. In conclusion, most responders ask neighbors and mother to get informations about weaning, and the incorrect knowledge from them could cause inadequate weaning practice and induce bad diet habit in their children. We have to find the reasons why they did not refer books or magazines frequently, and the way to resolve the problem.

This study was conducted to examine the effects of fish sauces from shrimp and anchovy and chitosan on the changes in pH, acidity, texture, and pectin fraction during Kimchi fermentation. Also, we conducted sensory evaluation on the textural properties of various Kimchis. The results were as follows: During fermentation, pH was decreased in the order of fermented anchovy sauce, fermented shrimp and control. And acidify was increased in the same order. But the addition of chitosan retarded the decrease in pH and increase in acidity. The compression force of various Kimchis during fermentation was decreased in the rder of fermented anchovy sauce, fermented shrimp, control and the addition of chitosan. During fermentation, hot water soluble pectin (HWSP) of control, fermented shrimp and fermented anchovy sauce increased whereas HCI soluble pectin (HCISP) in there treatments decreased. On the while, HWSP decreased and HCISP increased by addition of chitosan. Sensory score for the texture parameters such as hardness, crispness and chewiness of various Kimchis after the 3rd and 5th days of fermentation showed that hardness, crispness and chewiness were higher in chitosan treatment than in other treatments. The pH and acidity, compression force of Kimchis were appeared to be most highly correlated with crispness, showing that pH and compression force gave positive correlation and acidity gave negative correlation with crispness respectively. From the above results, chitosan addition was observed to infuluence the textural properties of Kimchi and their pectic substance.

This study was carried out to investigate the effects of washing time and the addition of sodium chloride(2%) on the quality characteristics of surimi made with chicken breast. The control(C) prepared from Alaska pollack was washed 2 times without sodium chloride. For the test treatments, ground chicken breast was washed 2 times only(T1), washed 2 times followed by the addition of sodium chloride(T2), washed 3 times(T3), washed 4 times with added sodium chloride(T4), washed 6 times(T5), and washed 6 times with added sodium chloride(T6) to produce chicken breast surimi. The $L^*,\;a^*$, W, shear force, and juiciness values were significantly higher, but the hardness, cohesiveness, gumminess, chewiness, aroma, flavor, and overall acceptability of Tl were significantly lower than those of the control(p<0.05). The $L^*$ value decreased as the washing time increased, and the $a^*$ and W values were significantly higher, however the hardness, breaking force, gel strength, shear force, and overall sensory scores of the samples washed 2 times were lower than those washed 4 and 6 times (p<0.05). The $L^*,\;b^*$, and shear force values were significantly lower but the $a^*$, W, hardness, cohesiveness, gumminess, chewiness, folding test results and overall sensory scores were significantly higher due to the addition of sodium chloride (p<0.05). The correlation coefficients(r>0.6) for the overall sensory scores and other items were positive for the folding test, cohesiveness, gumminess, chewiness, and flavor, but negative for shear force(p<0.05). Overall, T4 had the highest qualities and economic value among all treatments.

The objective of this study was to investigate the awareness of the meaning of a low-sodium diet as well as the self-reported preference of saltiness and sodium-intake related dietary behaviors for university students in Busan. A survey was conducted with 977 students (male: 512, female: 465). For the self-reported preference of saltiness, 45.8% of the participants reported 'moderate' preference, 35.3% reported 'salty' preference, and 18.8% reported 'unsalty' preference. Males had significantly higher scores than females (p<0.01). Regarding awareness of the meaning of a low-sodium diet, 20.8 % of the students did not recognize the phraseand, males had significantly lower awareness than females (p<0.01). The 'salty' group had a significantly lower rate than others (p<0.01). Males had significant higher sodium-related dietary behaviors scores than females for the following questions 'I often eat dried seafood and salted seafood', 'I usually eat all the broth in soups or stews' (p<0.01), 'I usually eat a lot of kimchi and salt-pickled vegetables', 'I usually eat soy dip or hot pepper dip with sushi and fritters' (p<0.05). Mean scores for sodium-related dietary behaviors by self-reported preference of saltiness were 2.49/5.00 (unsalty), 2.87/5.00 (moderate), and 3.19/5.00 (salty), respectively. There was a statistically significant difference between the groups (p<0.01). The lower the scores for the self-reported preference of saltiness, the lower the scores for sodium intake-related dietary behaviors (p<0.01). The average score for sodium-related dietary behaviors in the group familiar with the meaning of a low-sodium diet was significantly lower than that of the group that 'did not know' (p<0.01).

The purpose of this study was to compare knowledge on hypertension and blood parameters through blood pressure control of hypertensive patients commuting to a public health center. Hypertensive subjects were classified according to their blood pressures into a well-controlled group (SBP<140 mmHg and DBP<90 mmHg, n=44) and an uncontrolled group ($SBP\geq140mmHg\;or\;DBP\geq90mmHg$, n=41). All subjects were interviewed for clinical characteristics, effort for health maintenance and knowledge on hypertension and nutrition. Biochemical measurement of blood urea nitrogen, creatinine, triglyceride, total cholesterol, HDL-cholesterol and fasting blood glucose (FBG) were obtained from subjects. The knowledge about hypertension and effort for health maintenance were not significantly different between the groups. However, the nutrition knowledge score of the well-controlled group was significantly higher (p<0.05) than that of the uncontrolled group. On the test of nutrition knowledge, 97.7% of the well-controlled group answered correctly to the item, 'Medication is an easy way to control blood pressure'. This result was significantly higher (p<0.05) than that of the uncontrolled group of whom 82.9% answered correctly. Participants in both groups had only a little understanding about the importance of a balanced diet. Blood parameters were in the normal range and there was not a significant difference between the groups. However total cholesterol, triglyceride and fasting blood glucose levels of the uncontrolled group were higher than those of the well-controlled group. Therefore, education programs about the continuous control of hypertension through careful monitoring, medication, and exercise are required. The uncontrolled group was especially in need of strengthening education. Also more effective nutrition education programs about low salt, high fiber, low cholesterol, and balanced diets are required for hypertensive patients commuting to public health center.
