  • Recently, there has been a growing interest in using smart card data. However, there are restrictions on the utilization of data in many areas outside the Seoul metropolitan area because the data does not contain alighting information. This paper presents a methodology for estimating alighting stops of smart card data. Estimation results were verified by smart card data from Seoul and Gwangju. The estimation rates were 78.2% and 81.6% in Seoul and Gwangju, respectively. The matching accuracy was 54.2% and 33.4%, respectively. However, if up to two stops of error are allowed, the accuracy values were 93.6% and 94.0%, respectively. We also discussed changes in estimation results due to adjusting the allowable walking distance, which is a key parameter of trip chaining methods. As the allowable walking distance increases, the estimation rate increases, while the accuracy decreases, and it is found that the estimation results change by around 500m.

  • Objective: The study was carried to determine the interaction effects of pen enrichment and sex on behavioral activities, skin lesions and physiology of Windsnyer pigs. Methods: Forty-eight growing Windsnyer pigs of both sex, with an average initial body weight of 21.6 (${\pm}9.01$) kg were used. Four pigs were randomly assigned to either enriched or barren pens at a stocking density of $0.35m^2/pig$. Enriched pens contained 2 L bottles filled with stones and suspended at head level on ropes stretching across the pens. In addition, two plastic balls (90 mm in diameter) and 500 mL bottles (235 mm long) were placed on the floor of each enriched pen. Results: Pigs in barren environments had higher heart rates (p<0.001) than those in enriched pens. There was an interaction of pen environment and sex on rectal temperature (p<0.001). Females in enriched pens had higher rectal temperatures (p<0.05) than females in barren pens. There was no interaction of pen environment and sex on time spent eating and drinking (p>0.05). Time spent bullying was influenced (p<0.05) by pen environment and sex. Female pigs in barren environment spent more time on bullying than females in enriched pens. There was an interaction of pen environment and sex on time spent lying down and walking (p<0.05). Female pigs in enriched pens spent more time lying down than females in barren pens. Males in barren pens spent more time walking than males in enriched pens while no effect of pen environment was observed in females. There was an interaction of pen environment and sex on the number of skin lesions in the head, neck and shoulder region and other parts of the body (p<0.05). Conclusion: It was concluded that pen enrichment reduced the number of skin lesions and anti-social behaviors, especially for female pigs. There is a need, therefore of housing indigenous pigs under confinement.

  • Purpose: The purpose of this study was to explore the relationship between milk intake and prevalence rates of chronic diseases using KNHANES data, and the significance of the relationship was tested based on meditators, socioeconomic status (income, education), dietary behaviors (smoking, alcohol drinking, breakfast, and eating out), and physical activity (walking, medium, and high). Methods: Using the 5th and 6th survey data of KNHANES, milk intake rates and presence of seven chronic diseases were summarized and analyzed by ANOVA for two groups of adult men and women as follows: hypertension, hypertriglyceridemia, low HDL-cholesterol, diabetes, abdominal obesity, obesity, and metabolic syndrome. The dependent variables for the presence of seven chronic diseases regressed with socioeconomic, dietary behavior, and physical activity variables according to Logistic models. The dependent variables for milk intake using predictor variables of socioeconomic, dietary behaviors and physical activity were analyzed according to Logistic models. Finally, the significant socioeconomic, dietary behavior, and physical activity variables in the above model along with milk intake as a control variable or mediator variable regressed with significant chronic diseases according to Logistic models. Results: Milk intake, socioeconomic status, dietary behaviors, and physical activity were significantly different among the two groups of adult men and women, which were also critical factors to the prevalence of chronic diseases. The dependent variable for prevalence of chronic diseases regressed with significant factors of socioeconomic status, dietary behavior, and physical activity variables according to chronic diseases using the control or mediator variable of milk intake and summarized as follows: For adult men, milk intake controlled the education effect on diabetes partly, alcohol on hypertension and hypertriglyceridemia, low HDL-cholesterol, metabolic syndrome, breakfast on metabolic syndrome, eating out on obesity, and medium physical activity on hypertriglyceridemia. For adult women, household income on hypertriglyceridemia, diabetes, abdominal obesity, education level on hypertension, alcohol drinking, eating out, and walking activity on abdominal obesity, alcohol, breakfast, eating out, walking activity on low HDL-cholesterol, and medium physical activity on hypertriglyceridemia and low HDL-cholesterol were partly controlled by milk intake. Other significant socioeconomic status, dietary behavior, and physical activity variables related to prevalence of chronic diseases were fully controlled or mediated by milk intake. Conclusion: This study shows that milk intake (daily more than 200 g) prevents chronic diseases such as hypertension, hypertriglyceridemia, low HDL-cholesterol, diabetes, obesity, abdominal obesity, and metabolic syndrome.

  • The purpose of this study is to provide basic information for the development of pants patterns with a high level of fit and comfort through calculating surface variations of lower body parts by movement, grouping them into factors, and analyzing how their surface variations link to one another. The achieved results will help determine essential elements for constructing pants patterns, such as key measurements of lower body parts, the amount of ease values and selection of fabrics, which should be taken into consideration for allowing better movement in clothing. The study required lower body 3D scanning of women for analysis, and 13 women between the ages of 20-24 participated in the scanning, which was done by using Artec Eva 3D scanner. Their scanned data were digitalized and converted to measure the values of their lower body surface length and girth in pre-determined positions such as walking, stair climbing and sitting on a chair. These measurements have been statistically analyzed through SPSS 21.0 to obtain the average amounts and rates of extension for each of the measurement item. Some of the highlighted study results are as follows: The surface length and girth measurements were grouped into 4 factors based on their average extension rates. The results from correlation analysis between measurement items within each factor demonstrated that common items linked to all the changes in the values of other items in the three movements. But in most cases, items were not always correlated with each other for different movements. The results also showed that there were correlations between girth measurements, length measurements, and girth and length measurements. Therefore, key measurements for daily pants should be determined within reasonable estimations between relevant measurement items, while the measurements for work pants, which often withstand certain postures or repetitive movements, may require measurement items that are appro priate for, and closely related to, certain movements or tasks.

  • Two standard methods of cane length measurements were compared to find which methods really achieve the elbow flexion of 20 degrees to 30 degrees Twenty-four patients with hemiplegia who were ambulatory participated in this study. Method I : Length of the cane measured from the floor to the top of the greater trochanter. Method II : Length of the cane measured from the floor to the distal wrist crease with the arm at the side. Using an adjustable cane, each individual was fitted according to the two methods, and elbow angle was measured after each adjustment. The elbow angle according to Method I and Method II was $46.4{\pm}20$, $44.3{\pm}12.2$, respectively. No significant difference was found in the elbow angle or the cane length between the two methods. Of the 24 participants, 5(20.8%) measured according to method I and 3(12.5%) measured according to method II showed the elbow angle between 20 degrees and 30 degrees. These low predictive rates of agreement between ideal cane length and actually achieved elbow angle showed that these two methods which have conventionally been accepted as a standard to measure ideal cane length need to be revised through further research.

  • Ingrown toenails are most common among school-age children and adolescents though they can be observed at any age. Causes of ingrown toenails are increased curvature, trauma, and external pressure. Treatment of ingrown toenails can be broadly characterized as conservative and surgical. Conservative treatment can be performed using various methods, such as a gutter splint, dental floss, and cotton. Surgical treatments may be divided into two main approaches; narrowing of the nail plate and debulking of periungual tissues. However, these various conservative and surgical treatments have high recurrence rates, and thus, the author used a permanent surgical method based on the use of a paronychium flap to treat a 15-year-old male adolescent with excessive periungual tissues and curved ingrown toenails who did not improve despite conservative and several surgical treatments over 4 years. Subsequently, toenail shape was maintained without recurrence 22 months after surgery, and there were no complaints of inflammation or pain while walking. This simple surgical method can be performed on patients with advanced ingrown toenails due to excessive periungual tissues and nail curvature and can be expected to have permanent effects.

  • This cross-sectional descriptive study was conducted to determine the health conditions and health behaviors of merchants at traditional markets and compare them with members of the general population[ED highlight - do you mean "members of the general population"?]. The data were collected from 307 merchants at N traditional market in C City from 1-20 June 2015 at D Health Center of C City after physical measurement and blood collection and then analyzed using SPSS WIN 21.0. The male, female, and overall smoking rates of merchants at the traditional market were 34.2%, 3.5% and 11.1%, the annual drinking rates were 68.4%, 38.5%, and 45.9%, and the rates of subjects under stress and the rates of experiencing depression were 23.7%, 28.5%, and 27.4% and 5.3%, 6.1%, and 5.9%, respectively, which were all relatively lower than members of the general population[ED highlight - please ensure that my changes here are in keeping with your intended meaning.]. The male, female and overall rates of medium-level physical activities and walking were 32.9%, 19.9%, and 23.1% and 85.5%, 79.2%, and 80.8%, respectively, to have relatively good health behaviors, and the mental health is relatively fine than members of the general population[ED highlight - please clarify this, I cannot infer your intended meaning.]. However, test group[ED highlight - the test group? Please specify.] had high prevalence rates of hypertension, diabetes, hypercholesterolemia, and metabolic syndrome. Moreover, as the duration of work increased, the abdominal circumference as well as the prevalence rates of low HDL-cholesterol, hypertension, metabolic syndrome, and arthritis increased. Therefore, the specific causes of these shall be determined, and the long-term daily life improvement program shall be prepared and applied continuously for merchants at traditional markets.[ED highlight - please specify what these refer to; however, the entire sentence can probably be deleted.

  • In driving at evening or night, we are not able to recognize the speed bump and so stop suddenly. It could result in accidents. And also, we have a restriction of street light installation in farm road because it could be harmful to the crops and driver could not recognize the walking people. It needs to develop the speed bump with light and streetlight to be non harmful to the crops. So, we develop both the speed bump and streetlight with LED which could be non harmful to the crops and be increased recognition of walking people in farm road. For LED lighting power, we use the solar cells, and piezoelectric elements. It has automatic on/off according to power saving rates without illumination sensor. Minimization of circuit elements and design of minimum resisters and low power LED was used for power saving in assuring 3-days.

  • We investigated the effects of yohimbine and atipamezole in dogs anesthetized with xylazine-ketamine combination on electroencephalography (EEG) . Experiment groups were divided into three according to antagonists . Saline (1 ml) was used as an antagonist in group C, yohimbine (0.1 mg/kg) in group Y and atipamezole (50 ug/kg) in group A. Each group consisted of 5 dogs. Glycopyrrolate was injected 15 minutes prior to xylazine injection. Xylazine (1.1 mg/kg, IM) and ketamime (10 mg/kg, IV) were injected with the interval of 10 minutes. After 15 minutes, antagonists were administered intravenously. For EEG measurements, a recording electrode was positioned at Cz, which was applied to International 10-20 system. Heart rates, body temperature, respiratory rates, arterial blood pressure, $PaO_2$$PaCO_2$$PaCO_2$ at S4 in group Y was significantly decreased(p<0.05). Changes of electrolytes were not significant, except value of $Cl^-$ at S3 in group A. Mean head-up time (the time dogs showing head-up movement after antagonist injection, minutes) was $38.23^{\circ}$ae6.46 in group C, 2.54 $\pm$ 0.93 in group Y and 2.12$\pm$ 1.32 in group A. Mean sternal recumbent time (the time dogs showing sternal recumbency after antagonist injection, minutes) was 45.93$\pm$ 10.27 in group C, 11.91 $\pm$ 7.19 in group Y and 9.88$\pm$ 3.38 in group A. Mean walking time (minutes) was 53.49$\pm$ 9.21 in group C, 22.10$\pm$ 11.10 in group Y and 18.48$\pm$ 4.39 in group A. In group Y all dogs showed excitation and muscle rigidity in emergence. In group A, two dogs were also showed excitation and muscle rigidity, but were weaker than those of group Y.
