The purpose of this study was to reduce the drop out rates and enhance the quality of docent training education program in the Nature Heritage Center by providing educational services appropriate to the docents' needs based on the docents satisfaction survey. In this research, we conducted the survey to analyze the importance-satisfaction of natural heritage docent satisfaction in natural heritage docent training programs. The subjects of this survey were 30 docent in Natural Heritage Center. To develop a questionnaire, a factor analysis was conducted, as a result, 6 factors and 22 questions were presented. They are 'curriculum and instruction', 'advice for docent', 'educational environments', 'administrative services', 'support for docents', 'docent life'. The results of t-test, there was a significant difference between importance and satisfaction of the every 22 questions, the mean score of satisfaction(M=3.87, SD=.08) was lower than that of importance(M=4.10, SD=.20). According to ISA, the items located in "concentrate here" were deduced. They are 3 items from administrative services, device for docent, curriculum and instructions. To put in concretely, They were 'lecture content(subject)', 'teaching method', 'service attitude of personnel', 'interest in a docent' Based on these results and descriptive responses from the docents, the strategies for docent satisfaction in natural heritage docents training programs were suggested.
The purpose of this study was to investigate the effect of moxibustion heat therapy(Koryo hand acupuncture) on menstrual cramps. dysmenorrhea and ADL. The experiment was carried out during the period from March 24 to April 30, 2003. The subjects in the study were drawn from female students attending two colleges in Chungcheongbuk-do and Kyunggi-do. Of all those subjects. 19 and 14 subjects were assigned to the experimental and the control groups respectively. The moxibustion heat therapy were performed three times a week, subjects were treated twice a time. Data was analyzed using SPSS/WIN10.0 by $x^2$test. Wilcoxon sign rank. and Wilcoxon rank sum test. The result of this study were as follows : 1) After moxibustion heat therapy. the graphic rating score of menstrual cramps was decreased significantly from 7.79(SD=1.22) to 4.47(SD=2.25) in experimental group(z=-3.731. p=.000). And there was significant difference in the change of graphic rating score of menstrual cramps between both groups(z=-3.637. p=.000). 2) After moxibustion heat therapy. the score of face rating scale of menstrual cramps was decreased significantly from 3.95(SD=0.71) to 2.32(SD=1.00) in experimental group(z=-3.457. p=.000). And there was significant difference in the change of face rating score between both groups(z=-2.713. p=.007). 3) After moxibustion heat therapy. the score of adjective labor pain rating scale rank (ALPRS) of menstrual cramps was decreased significantly from 23.63(SD=4.19) to 17.27(SD=6.34) in experimental group(z=-2.941. p=.001). But there was no significant difference in the change of adjective labor pain rating score(ALPRS) of menstrual cramps between both groups(z=-1.918. p=.059). 4) After moxibustion heat therapy. the score of dysmenorrhea was decreased significantly from 7.0(SD=2.89) to 5.26(SD=3.54) in experimental group(z=-2.183. p=.029). But there was no significant difference in the change of the score of dysmenorrhea between both groups(z =-1.555. p=.125). 5) After moxibustion heat therapy, the score of ADL difficulty was decreased significantly from 33.26(SD=4.58) to 28.83(SD=9.44) in experimental group(z=-3.552. p=.000). And there was significant difference in the change of score of difficulty of ADL between both groups(z=-4.110. p=.000). The above finding indicated that the moxibustion heat therapy showed a practical effect on reducing menstrual cramps, dysmenorrhea and ADL difficulty in female. Accordingly. we can adopt the moxibustion heat therapy as a useful intervention in the community nursing.
Objective : This study aimed to identify the characteristics of hand function according to age and sex in older adults. Methods : This study included 103 healthy adults aged ${\geq}60$ years. The Korean version of TEMPA was used to assess hand function and a Jamar dynamometer and pinch gauge were used to assess hand and pinch strength in all participants. Results : The results of hand function assessment showed that speed of task execution (mean = 121.32 s, SD = 18.07 s in subjects aged 60-69; mean = 144.97 s, SD = 28.43 s in subjects aged 70-79; and mean = 160.93 s, SD = 38.33 s in subjects aged ${\geq}80$, p < .001) and fine movement (mean score = -.14, SD = .40 in subjects aged 60-69; mean score = -.63, SD = 1.07 in subjects aged 70-79; and mean score = -.57, SD = .65 in subjects aged ${\geq}80$, p = .01) decreased significantly with age. The male group showed better speed of task execution (mean = 133.54, SD = 22.83 in males vs. mean = 150.55, SD = 39.89 in females, p < .01) and fine movement (mean score = -.16, SD = .37 in males vs. mean score = -.46, SD = .58 in females, p < .01) than the female group. Hand strength also decreased significantly with age (p < .05, to p < .001). Conclusion : Occupational therapists should be aware of the decline in hand function (especially speed of task execution and fine movement) and strength in older adults, as well as the need to provide interventions to treat this decline.
In this study, extracts of chlorella using different extraction methods were compared for antioxidant activities and spray-dried chlorella powders were investigated for their physicochemical characteristics. The DPPH radical scavenging activity and superoxide radical scavenging activity of 50% ethanol extract were 29.19%, and 48.91%, respectively. The oxygen radical absorbance capacity (ORAC) of the 50% ethanol extract ($150.44{\mu}M/g$) was higher than those of other extracts. The total chlorophyll content of the 50% ethanol extract (542.89 mg/100 g) was higher than those of other extracts. The microencapsulation of the 50% ethanol extract was manufactured by spray-drying with 10 % maltodextrin (SD-C10), 20% maltodextrin (SD-C20), and 30% maltodextrin (SD-C30). The particle size of the freeze-dried powder ($454.47{\mu}m$) was higher than those of the spray-dried powders ($24.15{\sim}32.49{\mu}m$). Scanning electron microscope images showed that the spray-dried chlorella powders using SD-C10, SD-C20, and SD-C30 had an uniform particle distribution. The water absorption index and water solubility index (WSI) of powders were 0.31~0.45, and 96.96~98.28%, respectively. The spray-dried powders showed the stability in total chlorophyll content for 40 days storage. Based on these results, spray-dried chlorella powders could be used in various types of food processes.
This study aims to objectively and quantitatively determine the social emotion of empathy by collecting pupillary response. 52 subjects (26 men and 26 women) voluntarily participated in the experiment. After the measurement of the reference of 30 seconds, the experiment was divided into the task of imitation and spontaneously self-expression. The two subjects were interacted through facial expressions, and the pupil images were recorded. The pupil data was processed through binarization and circular edge detection algorithm, and outlier detection and removal technique was used to reject eye-blinking. The pupil size according to the empathy was confirmed for statistical significance with test of normality and independent sample t-test. Statistical analysis results, the pupil size was significantly different between empathy (M ± SD = 0.050 ± 1.817)) and non-empathy (M ± SD = 1.659 ± 1.514) condition (t(92) = -4.629, p = 0.000). The rule of empathy according to the pupil size was defined through discriminant analysis, and the rule was verified (Estimation accuracy: 75%) new 12 subjects (6 men and 6 women, mean age ± SD = 22.84 ± 1.57 years). The method proposed in this study is non-contact camera technology and is expected to be utilized in various virtual reality with smart glasses.

Distributions of serum dopamine-${\beta}$-hydroxylase(DBH) activity and thermostability in a randomly selected population of Korean adults were studied to investigate the genetic factor which could exert an influence on the serum DBH activity and thermostability. The results were followings: 1. The mean serum DBH activity in a randomly selected population of adults was $18.3{\pm}4.5$ umol/min/l($mean{\pm}SD;n=327$) which showed no age or sex variation. 2. The frequency distribution showed no isolated subgroup with very low serum DBH activity. 3. When the ratio of enzyme activity after heating $55^{\circ}C$ for 20 minutes to that before heating (heated-to-control or H/C ratio). was used as a measure of thermostability, the mean serum DBH H/C ratio in a randomly selecfld population, of adults was $0.90{\pm}0.17(mean{\pm}SD; n=327)$ which showed no age or sex variation. 4. Serum DBH H/C ratio showed unimodal, homogeneous distribution. 5. There was significant negative correlation between serum DBH activity and H/C ratio(r=-0.39. p<0.01). 6. Subjects with H/C ratio less than 0.1 had significantly higher basal enzyme activity $(22.2{\pm}4.5)$$(mean{\pm}SD;n=33)$ umo1/min/1 than those with H/C ratio more than 1.09 $(15.5{\pm}3.3)$$(mean{\pm}SD;n=32)$ umo1/min/1. This study shows that the distribution patterns of serum DBH activity and thermostability of Korean population are considerably different from those of Caucasian and it might be a line of evidence for the different inheritance pattern of plasma DBH enzyme between these racial groups.
This study investigated the effect of salt preference on dietary habits and the body composition of university students. The subjects were divided into two groups: 85 students who dislike salt (salt-dislike (SD) group) and 104 students who like salt (salt-like (SL) group). We found that the SL group showed a higher preference for sweet, sour, spicy, and bitter flavors compared to the SD group. There was no significant difference in the frequency of eating breakfast according to the salt taste preference. The meal speed of the SL group was significantly higher than the SD group (p<0.01) and the body mass index of the SL group ($22.59kg/m^2$) was higher than SD group ($21.04kg/m^2$). The fat mass of the SL group (15.30 kg) was higher than the SD group (12.80 kg) (p<0.01). Salt preference and snack intake frequency had a significant and positive correlation with fat mass. The frequency of eating breakfast, and meal speed also showed a significant and positive correlation with subcutaneous fat. In conclusion, the SL group eats relatively more, speedily and frequently intakes snacks and carbonated drinks, likely resulting in higher body and subcutaneous fat. These results suggest salt preference is related to food choice, influences unreasonable eating habits, and possibly changes body composition. Taste preferences should therefore be considered for dietary consulting and nutritional education.

Physiological responses (hematological factors, cortisol, glucose, osmolality, $Na^+$, $K^+$ and $Cl^-$) in starry flounder Platichthys stellatus were investigated during freshwater acclimation in the conditions of different speeds in salinity change with acute-decrease (AD) or stepwise-decrease (SD I and II). In AD of acute-decrease salinity, hematocrit (Ht), red blood cell (RBC) and hemoglobin (Hb) were rapidly increased more than SD I of stepwise-decrease salinity. But in case of SD II, Ht, RBC and Hb were no significant difference from beginning to end of this experiments. In AD, cortisol level significantly increased from $2.1{\pm}1.0{\mu}g/mL$ at the beginning to $13.7{\pm}0.2{\mu}g/mL$ at 6 hours and recovered to the basal levels ($3.1{\mu}g/mL$) at 10 days. In SD I, cortisol level was significantly increased from $2.1{\pm}1.0{\mu}g/mL$ at the beginning to $13.6{\pm}0.6{\mu}g/mL$ at 6 hours and recovered to the basal levels ($3.1{\pm}0.4{\mu}g/mL$) at 10 days. In SD II, cortisol level was a little increased from $2.1{\pm}1.0{\mu}g/mL$ at the beginning to $10.5{\pm}2.5$, $10.8{\pm}5.6{\mu}g/mL$ at 6, 12 hours and recovered to the basal level at 48 hours. Glucose level of AD, SD I, II were no significant difference from beginning to end of this experiments. Osmolality was $286.8{\pm}3.3\;mOsm/kg$ at the beginning. In SD II of stepwise-decrease, osmolality was no significant difference during rearing in freshwater (FW). But AD of stepwise-decrease and SD I of stepwise-decrease, osmolality was a little decreased end of this experiments. In AD of acute-decrease, only $Cl^-$ level was showed no significant difference from beginning to end of experiment and $Na^+$, $K^+$ levels were decreased. In case of SD I, $Cl^-$ level was showed no significant difference from beginning to end of experiment and $Na^+$, $K^+$ levels were decreased.

Purpose : Being small for gestational age (SGA) is a risk factor of short stature in children. Genetic background such as mid-parental height (MPH) is known to influence growth of children born SGA. We studied the relationship between growth of children born SGA and MPH and studied the effects of insulin-like growth factor (IGF-I) and insulin-like growth factor binding protein 3 (IGFBP-3) on postnatal growth in children born SGA according to MPH. Methods : Forty-nine neonates born SGA were included in this study. We defined corrected height standard deviation score (cHtSDS) by modified height SDS (HtSDS) based on their MPH. We categorized subjects into group 1 consisting of children with cHtSDS ${\geq}0$ (n=35) and group 2 consisting of children with cHtSDS <0 (n=14), and compared IGF-I and IGFBP-3 between the two groups. Results : The HtSDSs and cHtSDSs in groups 1 and 2 were $0.06{\pm}1.05$ vs. $-0.95{\pm}0.85$ (P=0.000) and $0.78{\pm}0.93$ vs. $-0.46{\pm}0.67$ (P=0.000), respectively. IGF-I SDS was higher in group 1 than in group 2 ($2.82{\pm}3.69$ vs. $0.23{\pm}2.42$, P=0.012). Total cHtSDS ($0.42{\pm}1.03$) was significantly higher than HtSDS ($-0.22{\pm}1.10$) (P=0.000). Conclusion : Our results show that cHtSDS differs significantly from HtSDS. Growth assessment by standardized growth curve does not uniformly show effects of genetic factors. A more accurate assessment of growth uses a personalized corrected growth curve that considers the genetic factor measured by MPH.
We developed a dietary supplement using natural herbs and nutrients for the growth and exercise performance improvement. It called 50-22 supplement containing distilled extracts of natural herbs to remove bitterness and the addition of Vitamin B1, B6, Ca and xylitol. We investigated on the effect of 10-22 supplementation on the maximal exercise performance, IGF-1 (insulin like growth factor-1) concentration and antioxidant activity in SD rat model. In result, JR-22 supplement group was better than control group about 10% in exercise performance test and increased about 63% of IGF-1 concentration in blood. In addition, the oxidative damage induced by exercise was reduced by JR-22 supplementation. Therefore, we suggested that 50-22 supplementation enhanced effectively exercise performance and IGF-1 concentration and reduced to oxidative stress in muscles. Also, we analysed biochemical factors in blood for the safety of JR-22 supplement. We known that there is no change of blood lactic acid, ammonia, inorganic phosphorous ion and creatine kinase activity. (Korean J Community Nutrition 8(3) : 349∼355, 2003)
