The purposes of this study were to examine bakery cafe use and to identify differences according to gender and age. The questionnaires developed for this study were distributed to 320 males and females aged 20 and over in Seoul. A total of 285 questionnaires were used for analysis(89.1%) and the statistical analyses were completed using SPSS Win (12.0) for descriptive analysis and $x^2-test$. Over 80% of customers used bakery cafes once a month or less, and female customers visited more often than males. The main reasons for using bakery cafe were to chat and then, to buy and eat bakery products. There was a significant difference by age. Average time consumed at a bakery cafe was usually under 1 hour and 30 minutes. Female and younger customers stayed longer than male and older customers, respectively. The majority of customers(85.6%) were accompanied by 2 or less guests and there was no significant difference between the groups. The expenses per person per visit were usually $3,000won{\sim}10,000won$, and the percentage of customers who spent at least 15,000 won was highest in those aged 41 and more. The groups with different gender and age also differed in their choices of products. Customers who are female or under 41 years old used coffees or beverages more often than other group customers. There was no significant difference in understanding on bakery cafe between groups, and 64.9% of respondent answered that they understood bakery cafe as a complex of bakery and cafe. Overall, for early settlement and development of the bakery cafe industry, it seems very important to establish marketing strategy that meets target customers' needs on the basis of understanding their patterns of bakery cafe use.

Background: The study of the medial antebrachial cutaneous nerve (MABCN) is an underused electrodiagnostic tool. But its use is often crucial for assessing mild lower brachial plexus or MABCN lesions, and sometimes for differentiating an ulnar mononeuropathy from a lower brachial plexopathy. This study was designed to know the difference of amplitude and velocity in a stimulation method (orthodromic vs antidromic), side of an arm and sex according by age. Method: MABCN conduction studies were performed orthodromically and antidromically in 90 subjects (42 women and 48 men, ranging from 22 to 79 years of age). We divided subjects into three groups by age (group 1: 20-39 years, group 2: 40-59 years, group 3: 60-79 years). The mean sensory nerve action potential amplitudes and sensory nerve conduction velocities in each group was compared by stimulation method, side of an arm and sex. Result: The amplitudes and velocities made a significant difference between orthodromic and antidromic method in all age groups. At comparison in amplitude and velocity by side of an arm, only amplitude was significantly higher in right arm than left by any stimulation method. The amplitudes and velocities were of no statistically differences in sex except amplitude checked orthodromically in right arm. Conclusion: This study suggests that there is the differences in conduction study of MABCN by stimulation method and side of an arm.

This study was conducted to investigate how child-care teachers participate, practice mealtime instruction, and perceive difficulties in food service, focusing on comparison between the teachers caring two different age groups: children younger than three years (Younger Group) and those three years or older (Older Group). Questionnaires were distributed to 151 child-care centers in Kwanak-gu, Seoul, Korea during December, 2011. Only the data from 25 child-care centers, where two respective teachers in charge of Younger Group and Older Group completed the questionnaires, were analyzed. The results showed that there was no difference in terms of child-care teachers' participation in food service practice between the two groups, except for serving method; 'Pre-plated' serving was used significantly more often in Younger Group, whereas 'Line-up' serving was used in Older Group. Approximately, three quarters of the child-care centers had policies or guidelines on mealtime instruction. During mealtime, child-care teachers tended to use frequently verbal instructions such as "sit up straight when you eat" about eating manner, "don't be picky with your food" about eating habit, and "wash your hands before eating" about eating procedure in both the groups. There was no statistically significant difference regarding child-care teachers' perceived difficulties in food service between the two groups. These results indicated that child-care teachers' participation and mealtime instruction in food service did not differ between the two age groups, although children's development of digestion and eating skill differed by age. Therefore, training should be provided to child-care teachers about food service practices and mealtime instruction appropriate to children's age.

The objectives of this study were to examine the growth pattern of infants by anthropometric measurement according to the 5 feeding practices of infants with the subject of two hundred healthy newborn babies from their birth till sixty month of age at intervals of two months. Breast group(BF, n=38), formula group(FF, n=102) and mixed group(ME, n=14) were fed breast milk, formula milk, breast and formula milk, from birth till 6 mo. of age, respectively. Convert 1 group (C1F, n=14) and covert 2 group(CF, n=32) were fed breast milk and mixed milk at 2 mo. of age afterthat switched to formula milk, respectively. From these, the following results were made. All the infants of this study showed superiority to Korean standard growth rate in regards to each growth item for each month age. In the case of males, at their birth, the subscapular skinfold thickness and the total skin fold thickness in the BF group was significantly larger than in MF group and FF group(p<0.05). At 6th month age, the chese circumference of MF group was 45.9cm, and significantly larger than those of BF, FF and C2F groups(p<0.05). In the case of females, at theri birth and 2nd month age, there was no difference among all the feeding groups in regards to each growth rate. At 4th month age, the Kauf index of C1F group was 16.21 and significantly lower than those of four groups(p<0.05). And total skinfold thickness in BF group was larger than in C1F group. The increase rate per month age of all growth items were larger at 2nd month age than at the later months both in males and in females. And until 2nd month age males showed more increase than females in regards to each growth item but after 2nd month age, this sapect did not show up. Multiple linear regression was used to determine predictive factors for infant growth. It was expected that at 6th month age, in the measurement of head circumference and chest circumference and cross-sectional fat area, BF-males were bigger by 22-39% of the explanation index than the infants of other groups. As a result, in spite of the significant lower intakes of energy and nutrients in breast-fed infants than in formula-fed infants, breast-fed infants showed more growth than the average of Korean infant standard growth rate at every month age, and showed no significant growth difference among feeding groups.

Using the hematofluiorometer normal values of the erythrocyte zinc protoporphyrin(ZPP) and ZPP/Heme ratio were measured in 312 males and 163 females aged from 6 month to 73 years old and compared with those of anemic persons. The mean$\pm$SD values of ZPP of normal Koreans were 28.5$\pm$6.4($\mu\textrm{g}$/dl) in males and 3.18$\pm$7.7 in females. the mean$\pm$SD of ZPP/Heme ratio were 49.5$\pm$12.3($\mu$mol/mol heme) in males and 62.0$\pm$15.8 in females. The difference in the mean ZPP and ZPP/Heme ratio values between male and female subjects were statistically signficant(p<0.0001) In male subjects the mean ZPP and ZPP/Heme ratio of the age groups less than 15 years old were higher than adult groups and the difference between age groups was significant(p<0.005 and p<0.0001 respecti-vely) The normal upper limit of the mean$\pm$2SD in normal male and female subjects were 41.3 and 47.2 for ZPP and 74.1 and 93.6 for ZPP/Heme ratio respectively. The mean values of ZPP and ZPP/Heme ratio measured in the anemic persons were higher than those of normal subjects and did not show any significant difference by the sex and age groups except in 6-14 years male groups. The test specificity(positivity) analyzed in the anemic persons by the cut-off values calculated from the normal data were 50.6% for ZPP and 73.0% for ZPP/Heme ratio. The correlation analysis between blood hemoglobin and erythrocyte ZPP or ZPP/Heme ratio in the total 801 normal and anemic subjects showed that there are very high logarithmic correlation between the hemoglobin levels and ZPP/Heme ratio (r=-0.8339) and high correla-tion between the hemoglobin levels and ZPP concentrations(r=-0.6372) These results suggested that the measurement of the erythrocyte ZPP and ZPP/Heme ratio with the hematofluorometer can be a usuful screening method for iron deficiency anermin because they provide a reliable immediate results with a small amount of sample and are relatively simple and inexpensive.

The purpose of this study is to propose the information and idea that can be applied to color planning by investigating preferred color according to ages, items by distribution of 30s~50s women. As the survey method, questionnaire survey and one-to-one investigation by preparing the color table of basic color and trend color were conducted, and total of 280 questionnaires were used for statistical analysis. The results of this study areas follows. First, in basic color, there were significant differences in preferred hues and tones by age groups. The preferred hues were N, PB in all ages, and the higher the age, the more people preferred vivid tones. Second, in basic color, there was significant difference in preferred hues of jumpers, one-pieces by distribution, and the preferred hue was found to be N in the items except jumpers. There were significant differences in preference tones of all items according to distribution. Third, in trend color, there was no significant difference in preferred hues by age groups. Preferred tones had significant differences by distribution, and the higher the age, the more people preferred vivid tones. Fourth, in trend color, some items had significant differences in preferred hues and tones by distribution. B was preferred in all age groups, and vivid tones were more preferred in wholesaler than the department store. Based on these results, this study proposed 30s~50s women's wear color planning idea that applied consumers' preferred color according to ages and items by distribution.

Purpose ; Iension-type headache is the most common headache. The effect of acupuncture for headache is already known, but the methods and technique of acupuncture is varied. Choice of acupuncture points is mostly relied on experience. Moreover, objective evaluation of acupuncture effects is lacking. Objective ; The objective of this study is to assess the difference of effects between dry needling on trigger point and dry needling on remote acupuncture point. The patients who were diagnosed as tension-type headache and administrated herb-medication were divided into two groups: Trigger point dry needling group and remote acupuncture point dry needling group, matching in sex, age. The degree of pain was measured by visual analogue scale(VAS) two times, before and after dry needling. Conclusion ; VAS showed significant decrement after dry needling on tension-type headache in both groups, but there was no statistically significant difference between two groups according to sex, age and duration. In addition, it is not statistically approved that there exists the difference of VAS between two groups about the treatment effects.

The purpose of this study was to compare the growth development between age-matched 51 postmenarcheal girls (mean age 153.1$\pm$5.8 month) who were rapidly maturing and 51 premenarcheal girls (mean age 153.1$\pm$5.7 month) who were slowly maturing. Anthropometirc measurements were taken for height, body weight, body fat(%), waist and hip circumferences of subjects. These measurements of menarcheal girls were significantly higher than those of nonmenarcheal girls. There was no significant difference in BMI distribution between two groups. However, 43.2% and 20.0% respectively in the menarcheal and nonmenarcheal girls had body fat levels of 30% or above. There were significant differences in the anthropometric measurements during past 4 years from 3rd grade elementary school to present. The greatest difference between the two groups were the amount and the rate of increased height and body weight from age 9 to 10. Among menarcheal girls, height, body weight, BMI, and Röhrer index were positively related to the onset of menarche. Distinctively, there was a stronger relationship between age at menarche and anthropometric measurements when the girls were 5th grade elementary school children. These findings support that during childhood and puberty, obese girls grow faster and have earlier menarche. Furthermore, the importance of prevention of obesity was recognized in order to accelerate growth of height among the girls by delaying the age of menarche.
