Purpose: Javals' rule is a commonly used formula for estimating total astigmatism from corneal astigmatism. Many researchers suggested a modication of Javals' rule. Therefore, we estimated the total astigmatism on the basis of measurements of corneal astigmatism and assessed the accuracy of Javals' rule. Methods: We estimated the total astigmatism on the basis of measurements of corneal astigmatism on 108 eyes of 54 subjects of koreans in their twenties. Results: The regression of the total astigmatism from corneal astigmatism is less than 1.25 of Javals' rule, but it was equivalent to Auger's modified Javals' rule. Conclusions: The regression equation for this study was as follows: Total Astigmatism=0.79 (Corneal Astigmatism)-0.49D${\times}$90.

The purposes of this study was to identify characteristics of total coordination in the pursuit fashion sensibility among women their 20's. A self-administered questionnaire was used for data collection from 410 women in their 20's. Data collection was conducted Aug. 5 to Aug. 15, 2009. Most women emphasized on clothing for total coordination and utilized clothing color and style as a selection criteria. They tried to match makeup and clothing, and spent more time considering makeup, hair styles, and fashion accessaries than clothing for their total coordination. Factors of fashion sensibility included luxury and fashion, casualness and ethnicity, modernity, sociality, activity, and sexual attractiveness and women were segmented into fashionably sensible intermediate, low, and high groups according to their fashion sensibility. The fashionably sensible intermediate group predominantly encompassed women who were unmarried or in their late 20's, unemployed, highly educated, or of low economic status, preferred to mixing and matching colors, and who utilized their individuality or makeup color for total coordination. The fashionably sensible low group encompassed homemakers, in their early 20's, high school graduates or university students, who utilized their clothing or hair color within their total coordination criteria. The fashionably sensible high group encompassed unmarried career women in their mid 20's or of high economic status, who spent much money on their clothing, makeup, hair styles, and fashion accessaries, who preferred achromatic, warm or cool colors, and utilized their individuality or fashion color.

Let G = (V,E) be a graph. A function $f:V{\rightarrow}\{-1,+1\}$ defined on the vertices of G is a signed total dominating function if the sum of its function values over any open neighborhood is at least one. The signed total domination number of G, ${\gamma}^s_t(G)$, is the minimum weight of a signed total dominating function of G. In this paper, we study the signed total domination number of generalized Petersen graphs P(n, 2) and prove that for any integer $n{\geq}6$, ${\gamma}^s_t(P(n,2))=2[\frac{n}{3}]+2t$, where $t{\equiv}n(mod\;3)$ and $0 {\leq}t{\leq}2$.

Purpose: The purpose of this study was to investigate the importance of initial screening tests for depression and anxiety disorders in children with headache. In addition, this study evaluated whether the Children's Depression Inventory (CDI) and Revised Children's Manifest Anxiety Scale (RCMAS) are suitable for screening symptoms of depression and anxiety. Methods: A retrospective chart review was conducted of 720 children aged 7-17 years who had visited a pediatric neurology clinic for headaches and were referred to a pediatric psychiatric clinic for psychiatric symptoms from January 2010 to December 2011. All patients completed the CDI and RCMAS. Among them, charts of patients with clinically significant total scores (cutoff>15) for psychiatric symptoms, as defined by the CDI and RCMAS scoring scales, were reviewed. Results: Nineteen patients had headaches and clinically significant total scores for psychiatric symptoms. The mean age at headache diagnosis was 11.7 years, and 57% were male. Mean duration of headache was 11.5 months. Two point eight percent of the patients were diagnosed with psychiatric disorders including major depression (1.7%), generalized anxiety disorder (1.1%), and bipolar disorder (0.1%). Four patients (0.6%) were diagnosed with attention deficit/hyperactivity disorder (ADHD). Total mean CDI and RCMAS scores of patients referred to the psychiatric clinic were 18.8 and 22.2, respectively. There was no correlation between CDI or RCMAS total scores and headache frequency, duration, or severity. Conclusion: We recommend that all patients with headache should be screened for depression and anxiety by CDI and RCMAS scores.

This study investigated the relationship between total sugar intake and obesity indices in 362 female university students. This study was conducted using an anthropometric checkup and 3-day dietary records. Subjects were categorized according to the total sugar intake as < 33.3 g (group I, n = 90), 33.3-56.1 g (group II, n = 91), 56.1-83.8 g (group III, n = 91), ${\geq}$ 83.8 g (group IV, n = 90). No significant differences in age, weight, height, body mass index (BMI), or the percentage of body fat were observed among the four groups. Based on BMI, 20.2% were overweight, and the percentage of body fat was > 30% in 67.1% of all students sampled. Energy intake in each groups was 1,164.7 kcal, 1,488.6 kcal, 1,590.0 kcal, and 1795.8 kcal, respectively (p < 0.001). Total sugar intake in the groups was 20.5 g, 44.6 g, 68.3 g, and 111.8 g, respectively (p < 0.001). Carbonated beverages were identified as the most significant food source for total sugar intake in female university students. The next major foods were ice cream, milk, coffee, fruit, sugar, cookies, bread, chocolate, corn syrup, rice, onion, maple syrup, pickle, and sweet potato. As intake of total sugar increased, intake of energy also increased significantly. Mean daily intakes of fat and calcium/1,000 kcal were significantly higher in group IV than those in the other groups. Mean daily intakes of vitamin C and vitamin E/1,000 kcal were significantly higher in group III than those in the other groups. The percentage of subjects who consumed nutrients below the estimated average requirement was less in the higher total sugar intake group than that in the lower intake group. The obesity indices (weight, BMI, % body fat) were not associated with total sugar intake in the subjects. We conclude that total sugar intake does not seem to influence obesity indices in female university students.

Liquid livestock manure (LLM) has been used as a nitrogen fertilizer source for horticulture plants. LLM contains organic nitrogen (N), ammonium, nitrate, and nitrite. The amount of nitrate and nitrite in LLM are usually small compared to the amount of ammonium in it and so they can be negligible if total nitrogen (N) concentration in LLM is higher than $1,000mg\;L^{-1}$. However, if total N concentration in LLM is less than $1,000mg\;L^{-1}$, the amount of nitrate and nitrite may affect total N concentration in LLM. Currently, Kjeldahl digestion method is mainly used for ammonium-N in LLM. Therefore, it is ineffective to analyze nitrate-N and nitrite-N. The objective of this study was to evaluate whether the total N concentrations are affected by the amount of nitrate-N and nitrite-N with diverse LLMs by Kjeldahl method (with and without Devarda's alloy after Conc. sulfuric acid digestion). Five liquid livestock manure samples were collected at swine farms in Ansung and Icheon. All LLM samples were stored at $25^{\circ}C$, subsampled at every $15^{th}$ day for 90 days, and analyzed for total N, ammonium-N, and nitrate-N. At the $90^{th}$ day, LLM samples were analyzed with and without Devarda's alloy after Conc. sulfuric acid digestion. Potassium nitrate, ammonium nitrate, and ammonium chloride were used to determine the N recovery percentages. Total N concentration ranged from 560 to $4,230mg\;L^{-1}$. Nitrate-Ns were found in all LLM samples, ranged from 21 to $164mg\;L^{-1}$. N recovery percentages with potassium nitrate were 0 % without Devarda's alloy and 100% with Devarda's alloy because adding Devarda's alloy facilitated nitrate-N into ammonium-N conversion. Total Ns were significantly different between two methods, with and without Devarda's alloy. Total N concentrations were $210mg\;L^{-1}$ at LLM 4 and $370mg\;L^{-1}$ at LLM 5 without Devarda's alloy and $290mg\;L^{-1}$ at LLM 4 and $490mg\;L^{-1}$ at LLM 5 with Devarda's alloy. These results suggest that if total N of LLM is less $1,000mg\;L^{-1}$, additional procedure such as adding Devarda's alloy can be used to estimate the total N and inorganic N better.

The current study examines PCC (percentage of correct consonant), speech intelligibility, and oral motor function between the group of typically developing children and the group of children with Down's syndrome. To 15 children with Down's syndrome (mean CA: 9;7) and 15 typically developing children on receptive language age, the following tests were administered: K-WPPSI (2001), Picture Vocabulary Test (Kim et al., 1995), Oral and Speech Motor Control Protocol for total oral functional score (Robbins et al., 1987), DDK and Assessment of Phonology and Articulation for Children (APAC, Kim et al., 2007) for PCC and speech intelligibility. Pearson correlation coefficients were computed for the total oral functional score, PCC and DDK of each group. The statistical analysis showed that there is no significant difference in total functional score and DDK when IQ was controlled. There was a significant correlation between total oral functional score and PCC in the Down's syndrome group and a significant correlation between total oral functional score and intelligibility in the Down's syndrome group whether IQ was controlled or not. The findings suggest that both cognitive ability and overall oral motor function need to be considered for the intervention to enhance PCC or speech intelligibility of children with Down's syndrome.

The purpose of this study is to investigate the gait characteristics in Parkinson's disease patients. Specifically, the total stance time and the ratio of each stance phase (heel strike, mid-stance, propulsion) are analyzed from the foot-pressure measurement system which requires low cost and small space compared to the conventional gait analysis system. The gait characteristics were analyzed in 23 Parkinson's disease patients (before and after L-dopa medication), 34 elderly (sixties) normal subjects and 21 young (twenties) normal subjects. Bradykinesia global score (self-developed score of slowness of body movement) of patients before medication was determined to see the relationship between the score and the gait characteristics. The total stance time was greater in the erde. of patients, elderly, youngs (p<0.05). The phase ratio of heel strike and propulsion was smaller and that of mid-stance was greater in the order of patients, elderly, youngs (p<0.05). However, there was no significant difference in the above gait characteristics of patients before and after medication. There was a tendency, though statistically non-significant, that the total stance time is longer and the propulsion phase ratio is shorter in patients with greater Bradikinesia global scale, and this tendency was relieved after medication.
