Purpose: This study aimed to assess the quality of life (QoL) of children with glycogen storage disease (GSD) and their parents and to determine the impact of myopathies. Methods: A prospective case-control study was conducted at the Cairo University Children's Hospital and National Liver Institute, Menoufia University. A promising new style of questionnaire called the Stark Quality of Life Questionnaire was used to assess the quality of life. Results: Fifty-two children diagnosed with GSD (cases) and 55 age- and sex-matched healthy children (controls) were included. A statistically significant difference was found between cases and controls regarding food intake; mental behavior parameters such as mood, energy, and social contact; and physical behavior parameters such as running and tying shoelaces. Children with myopathies had significantly lower QoL scores in most of the parameters. Conclusion: GSDs alter children and their parents' mental and physical abilities. Lower QoL scores were detected in children with both skeletal myopathy and cardiomyopathy, but the difference was not statistically significant when compared with the children without myopathies.

The purpose of this study was to examine the effect of diabetes education on diabetic management by determining the changes of the knowledge and practice for diet therapy and blood glucose level pre-training and post-training. Statistical data analyses were completed using the SPSS 11.0 program. The results can be summarized as follows : The average age of the subjects was 52.8 years old, the period of suffering from diabetes was 7.9 years and 31% of the patients had a history of diabetes in their family members. In life style for self-management, they showed lower levels in drinking post-training, and significantly higher exercise levels post-training (P<0.05). Regarding the level of knowledge for diet, they showed significantly higher levels post-training in eight items such as importance of diet therapy for diabetes (p<0.005), principle of diet therapy (p<0.005), nutrient composition of foods (p<0.005), carbohydrate composition of foods (p<0.005), calorie prescribed to themselves (p<0.001), exchange units prescribed to themselves (p<0.005), exchange food items and exchanges units of cereal & grains (p<0.005) and exchange food items and exchanges units of fruit & juices (p<0.005). Regarding the practices of diet, they showed significantly higher levels of practice in keeping permitted meal size (p<0.005), using food exchange list (p<0.005), keeping exact meal times (p<0.001) and restricting most foods to eat (P<0.01) post-training. When measuring their bodies, average weight was lower post-training. Obesity was significantly lower post-training (p<0.01), and blood pressure both in systolic and diastolic was lower. Postcardinal-2hour blood glucose level decreased significantly from 268.4$\pm$98.9 pre-training to 180.9$\pm$48.4 post-training (p<0.001).

Quality characteristics of mash of takju prepared by wheat flour nuruks (conventional and improved style) were investigated during fermentation. Those were cultured with wild microorganism on whole and crushed wheat (wheat nuruk), wheat flour and mixture of rice and wheat flour, and nuruk cultured with Aspergillus oryzae on wheat flour. Ethanol content reached maximum of 10.6-17.4% after 14 days of fermentation. And the ethanol contents of takju were high in order of wheat nuruk, wheat flour nuruk, Aspergillus oryzae nuruk and mixture of wheat flour and rice nuruk. No difference of pH was among the treatments while the wheat flour nuruk cultured with wild microorganisms contained higher amounts of acids than the others. The amount of total sugars ranged from 16.22-17.74% on the starting day of fermentation, and decreased to 4.28-6.10% after 14 days. The amount of total sugars in mashes brewed with wheat flour nuruk cultured with Aspergillus oryzae was measured to be highest at the beginning stage of fermentation. Afterwards no difference was found among the types of nuruks. Glucose was in the range of 2,735-7,842 mg% at initial period of fermentation, afterwards it was rapidly decreased. The total amounts of free sugar for control and the wheat flour nuruk was higher than other treatments. The total amounts of organic acids were the highest in wheat nuruk to 690-2,241 mg% and the contents of lactic acid and succinic acid were high in mixed rice nuruk to 183-1,293 mg%. The contents of lactic acid and succinic acid were higher than those of the other kinds of organic acids in takju.

This study was carried out to investigate the quality characteristics and antioxidant activity of Sulgidduk (oriental-style rice cakes) prepared with different amounts (0%, 2%, 4%, or 6%) of maquiberry (Aristotelia chilensis) powder. The moisture content of treated Sulgidduk ranged from 37.75% to 38.79%, with no significant differences between treatment groups. The pH gradually decreased with the increasie in maquiberry powder. The soluble solid content did not show significant differences between groups. The lightness (L) value decreased, while redness (a) value increased with the increase in added maquiberry powder. Hardness of the control group was lower than those of the treatment groups. Consumer acceptance test results revealed no significant differences in smell, taste and overall acceptability scores. The total polyphenol and total anthocyanin contents were 8.66~262.71 mg GAE/100 g amd 0.01~9.76 mg C3G/100 g), respectively. Moreover, the polyphenol and anthocyanin levels increased with increasing levels of added maquiberry powder. In addition. reducing power and 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activities significantly increased with increase in added maquiberry powder. Based on the above results, addition up to 6% maquiberry powder incorporated into Sulgidduk will meet the taste and functional needs for consumers.

The sacrificial foods using at 88 villages in Andong area where the village sacrificial rituals are performed, were investigated in 1994. The finding are as follows; 1. Since the village sacrificial rituals keep ancientry, white Baeksulki without any ingredients is used as Ddock (a steamed rice cake) in 74 villages, and in 5 villages the Baeksulki was served just in Siru (a tool used to prepare Ddock). The type of meat serving in rituals has been changing from large animal to small animal and the type of light from bowl-light to candle. 2. Though the ritual observes Confucianism style, memorial address was offered in 34 villages and only in 8 villages, liquor was served 3 times and the address was offered. In 60 villages, liquor was served only once, and calling village god, bowing twice, and burning memorial address paper were performed in order. Burning paper has been meaningful in rituals. 3. Tang (a stew) was served in 21 villages, and in 18 villages even Gook (a soup) was not used. The numbers of village which do not use cooked rice and Ddock are 14, respectively. 4. Fruits are essential in rituals foods. In 63 villages, 3 kinds of fruits are served and this is contrasted with even number of fruits in Bul-Chun-Wi Rituals. 5. In 25 villages, fish and meat are not served. As meat, chicken in 19 village are served. Meat Sikhae (a fermented rice beverage) prepared with meats or fish are served in 5 villages. Slice of dried meat is served in 73 villages commonly. 6. In gender of god for village shrine, woman in 43 villages, couple in 17 villages, man in 9 villages, mountain god in 2 villages, villages tree, etc were enshrined. In 52 villages liquor is served in rituals (liquor is used in 58 villages including serving god), in 28 villages sweet liquor (Gamju) is served for god (sweet liquor is used in 46 villages), and liquor, water, or sweet liquor is just displayed on table but not served in 8 villages. Incensing is found to be not common in village ritual, only in two villages it is performed. The most appropriate rituals food is thought to be pig for mountain god. Home dishes can not be used in village ritual and spoon is not used and chopstick is prepared from wild plant. Meat and fish are used in the raw.

We investigated the effect of PE film thickness on the modified atmosphere packaging (MAP) deastringency of 'Sanggamdungsi' (Diospyros kaki cv.) astringent persimmon at room temperature ($25^{\circ}C$) and low temperature ($-1^{\circ}C$). The fruits were individually packaged with PE film of which the thickness is 60, 80, 100, 115 or $130{\mu}m$ and stored at room or low ($-1^{\circ}C$) temperature. At room temperature, firmness shows the highest value (23.3-26.5) at $100{\mu}m$ thickness. Top flesh browning and decay was monitored at 20 days after storage, and peel blackening and style-end softening was negligible at optimal thickness. Therefore, optimal film thickness of deastringency at room temperature is $80-100{\mu}m$. At this thickness, the astringency was removed after 5 days and the fruits can be distributed until 10 days after the MAP. At low ($-1^{\circ}C$) temperature, firmness was maintained regardless of film thickness. However, the firmness is higher as the film is thicker. Top flesh browning and decay was not occurred even after 90 days after storage. Peel blackening and style-end softening was monitored at 90 days after storage. Off-flavor was monitored at 115 and $130{\mu}m$ thickness. Therefore, optimal film thickness of deastringency at low ($-1^{\circ}C$) temperature is $80-100{\mu}m$. At this thickness, the astringency was removed after 50 days and the fruits can be distributed until 80 days after the MAP.

This study was carried out to broadly profile the dietary pattern of elderly who consumed a higher amount of sodium compared to lesser sodium consumers. Na index 14, an instant food frequency questionnaire (IFFQ) of 40 items characterizing a high amount of sodium and a food frequency questionnaire of 63 food items that were used in nationwide surveys were adopted for the assessment of dietary characteristics of the subjects. The Na index 14 consisted of food items such as kimchi stew, bean paste stew, cooked spinach dish, seaweed soup, fish stew, roasted anchovy, and seasoned vegetables. Also, the survey constructs included nutritional knowledge and anthropometric measurements of the subjects. Out a total of 135 participants, 58 elderly were determined as the high sodium intake group (HSIG) and the other 77 were the control group, via a formerly validated Na index and sodium-associated dietary habits scale (SDH). Dietary habits of "add salt or soy sauce to foods", "drink up the broth of soups and stews", and "brined fishes and vegetables daily" were among the most significant differences between HSIG and control group in SDH assessment. In addition, the HSIG were less likely to have regular meals, adequate amount of meals, and nutritionally balanced meals than the control, with the differences manifesting more in females than males. Additional findings included that the HSIG possessed a poorer nutritional knowledge and obtained much higher scores on the IFFQ. Taken together, the study urges the needs of nutrition education for the elderly who habitually salt their foods and maintain a less desirable dietary style.

The effects of amylase addition during extrusion cooking of rice on the physico-chemical properties of the extrudates were investigated in order to develop rice-based Korean style weaning food products. A laboratory-built single screw extruder was used, the enzymes used were Termamyl 120LS(amylase from Bacillus licheniformis, NOVO Co.), BAN 240L(amylase from Bacillus amylolichuefaciens, NOVO Co.) and malt powder. By the addition of enzymes, the water soluble index of the extrudates increased by 3 times compared to that of the extrudates without enzyme and the concentration of reducing sugar in the extrudates increased drastically at 28 feed moisture. The gel permeation chromatographic pattern showed that the large molecular starch fractions diminished by the addition of enzyme during extrusion and the low molecular fraction increased. The residual enzyme activity in the extrudate were 27% for the most thermo-resistance enzyme by treating at $140^{\circ}C$ in the metering section of the extruder. The sediment volume of the extrudate dispersion increased as the metering section temperature increased to $140^{\circ}C$ . By the addition of enzymes the viscosity of extrudate dispersion was redused $1/4{\sim}1/200$ of that of the extrudates without enzyme. It allowed to use 1.8 times of solid material to the weaning food formulation to attain the same level of consistency as the commercial products. It proves that the addition of amylase during rice extrusion is effective to increase the energy density of weaning food by starch degradation, which results in the increases of water solubility, reducing sugar content, dispersibility and fluidability.

BACKGROUND/OBJECTIVES: This study addressed the question whether the composition of supposedly 'healthy' or 'unhealthy' dietary regimes has a calorie-independent short-term effect on biomarkers of metabolic stress and vascular risk in healthy individuals. SUBJECTS/METHODS: Healthy male volunteers (age $29.5{\pm}5.9years$, n = 39) were given a standardized baseline diet for two weeks before randomization into three groups of different dietary regimes: fast food, Mediterranean and German cooking style. Importantly, the amount of calories consumed per day was identical in all three groups. Blood samples were analyzed for biomarkers of cardiovascular risk and metabolic stress after two weeks of the baseline diet and after two weeks of the assigned dietary regime. RESULTS: No dietary intervention affected the metabolic or cardiovascular risk profile when compared in-between groups or compared to baseline. Subjects applied to the Mediterranean diet showed a statistically significant increase of uric acid compared to baseline and compared to the German diet group. Plasma concentrations of urea were significantly higher in both the fast food group and the Mediterranean group, when compared to baseline and compared to the German diet group. No significant differences were detected for the levels of vitamins, trace elements or metabolic stress markers (8-hydroxy-2-deoxyguanosine, malondialdehyde and methylglyoxal, a potent glycating agent). Established parameters of vascular risk (e.g. LDL-cholesterol, lipoprotein(a), homocysteine) were not significantly changed in-between groups or compared to baseline during the intervention period. CONCLUSIONS: The calorie-controlled dietary intervention caused neither protective nor harmful short-term effects regarding established biomarkers of vascular or metabolic risk. When avoiding the noxious effects of overfeeding, healthy individuals can possess the metabolic capacity to compensate for a potentially disadvantageous composition of a certain diet.

The study was done to determine the reliability and validity of a life style questionnaire for the elderly. The questionnaires were sent to 16,524 elderly people who were beneficiaries of Korean Medical Insurance Corporation in Pusan. Among the completed 9,139 questionnaires, 200 were randomly sampled and retested. finally, 110 duplicates were collected. Weighted kappa-value and Pearson correlation coefficients were estimated to measure the reliability. Validity coefficient was estimated by using reliability coefficient. In self-self responses, reliability coefficients of the most of items were over 0.6 except some physical activity related item. Relatively high reliability was observed in smoking, alcohol related items and anthropometric items. In self-proxy responses, most of the physical activity related items were found to be less reliable than self-self responses. Smoking and alcohol related items were consistently reliable. Male showed higher validity in food related item than female. On the other hand, some of the physical activity related items and smoking and alcohol related items were less valid in male than female. With regard to bias of proxy respondents, offsprings tended to underestimate the frequency of house cleaning' and 'kitchen work' and overestimate the height of them. In conclusion, the life style questionnaire was found to be reliable in the most of items. But, some items related with physical activity were found to be somewhat less reliable. Sexual difference on the validity was identified in some items. With regard to bias of proxy respondents, offsprings tended to have bias in part of items of housework and anthropometry.
