  • We compared with heavy metal concentration of herbal medicines in products of Gyeongbuk and the other area of Korea. The concentration of heavy metal were studied for the estimation of quality in herbal medicines which is Bupleuri Radix, Paeoniae Radix, Dioscoreae Rhizoma and Astragali Radix in products of north Gyeongbuk area. The average levels of heavy metal of herbal medicines in Gyeongbuk area are as follows : Mercury is 0.037mg/kg, Chromium is 0.093mg/kg, Nickel is 0.108mg/kg, Copper is 0.475mg/kg, Zinc is 3.14mg/kg, Manganese is 1.52mg/kg, Iron is 7.83mg/kg, and Cadmium, Lead and Arsenic is not detected. It was very lower in concentrations than those of average Korea area. Therefore, Gyeongbuk area appear to be more proper to cultivated land than other area.. Minerals such as Ca and K were extracted more than Na and P in herbal medicines products of Gyeongbuk respectively. Minerals and heavy metal concentrations distributed in herbal medicines were analyzed. Little or no relationship was observed between minerals and heavy metals.

  • The concentration of heavy metal were studied for the estimation of quality in herbal medicines which is Bupleuri Radix, Paeoniae Radix, Dioscoreae Rhizoma and Astragali Radix in products of north Gyeongbuk area. And we collected soils from several area in Gyeongbuk, and determined heavy metal concentration of soils by ICP. We compared with herbal medicines in products of Gyeongbuk and their soils. For the heavy metals contents of Gyeongbuk area, in Gong Jung Ri, represented the higher level, it may be due to a near the road. The Cd contents in soil was not a wide difference. For the As and Pb contents in soil, Song Sa Ri (Bupleuri Radix) represented the higher level (0.68mg/kg, 1523rng/kg). Heavy metal contents in cultured herbal medicines and their soils did not give reproducible results. But the degree of correlation between a few heavy metal contents of Dioscoreae Rhizoma and their soil showed the good transfer from the soil.

  • Johne's disease is a chronic inflammatory bowel disease of cattle, sheep, goats and other ruminants, and Mycobacterium paratuberculosis is the etiologic agent of this disease. Many studies have been carried out on paratuberculosis from daily cattle and Korean native cattle in multiple areas around nation, but there is no report in Eastern-Gyeongbuk area. The purpose of this study is to investigate the seroprevalence of bovine paratuberculosis in Eastern-Gyeongbuk area. From July to December in 2007, blood samples were collected from 363 dairy cattle of 27 farms and 281 Korean cattle of 114 farms and the ELISA was conducted. 25 (6.9%) dairy cattle of 6 (22%) farms and 19 (6.8%) Korean cattle of 8 (7.0%) farms were positive in ELISA. In regional analysis, 25 (8.3%) out of 300 dairy cattle in Gyeungju were positive and Pohang were negative in this research. 12 (16.4%) out of 73 Korean cattle in Gyeungju and 7 (9.6%) out of 73 Korean cattle in Uljin were positive. Pohang and Youngdeok of Korean cattle were negative in this research. According to raising scale of dairy cattle, 4 (66.7%) farms out of 6 farms were raising 30 below and 2 (33.3%) farms out of were raising 30$\sim$70. And there were negative raising scale more than 70. In Korean cattle, 6 (75%) farms out of 8 were raising below 10 and 2 (25%) farms were raising 10$\sim$30. And there were negative raising scale more than 30. The rate of seropositive of paratuberculosis dairy cattle and Korean cattle were similar and the positive rate of Eastern-Gyeongbuk area is reported lower than that of any other region.

  • The microblade cutting method, so-called SAICAS, is widely used to quantify the adhesion of battery composite electrodes at different depths. However, as the electrode thickness or loading increases, the reliability of adhesion values measured by the conventional method is being called into question more frequently. Thus, herein, a few underestimated parameters, such as friction, deformation energy, side-area effect, and actual peeing area, are carefully revisited with ultrathick composite electrodes of 135 ㎛ (6 mAh cm-2). Among them, the existence of side areas and the change in actual peeling area are found to have a significant influence on measured horizontal forces. Thus, especially for ultrahigh electrodes, we can devise a new SAICAS measurement standard: 1) the side-area should be precut and 2) the same actual peeling area must be secured for obtaining reliable adhesion at different depths. This guideline will practically help design more robust composite electrodes for high-energy-density batteries.

  • This study provides preliminary data to help organize improvements in analyzing the importance and performance of sanitation management items and the management of foodservice facilities in Community Child Centers in Daegu and Gyeongbuk Area. Questionnaires were distributed to 173 participants in sanitation and safety education at the center from April~June 2013 and 121 questionnaires were used as analysis data to investigate the management of foodservice facility at Community Children Centers in Daegu Gyeongbuk area. Most of the Community Child Centers are privately owned, and 62.0% had 20 to 29 children. Only 6.6% and 50.4% of the centers had nutritionists or cooks, respectively, due to budget deficits, and the foodservices were run by employees holding other positions. An investigation of sanitation management found that 84.3% of employees had a regular health inspection with significant differences between Daegu and Gyeongbuk (p<0.05). Most of the sanitation education was necessary, and the contents of sanitation education were applied to the fields in 66.1% of facilities. The reasons why the contents of them were not used in the fields included, the shortage of facilities and devices at 20.7%, which was the most common explanation. The separation separated of contaminated and non-contaminated areas were observed in 45.5% of facilities (p<0.01), separated sinks for pre-processing and cooking were found in 50.4%, and a show significant higher rate was noted in Daegu than in Gyeongbuk (p<0.05). An interior wall and, floor tile installation were observed 43.8% of facilities and a significantly higher rate was noted in Daegu than in Gyeongbuk (p<0.05). 30.9% of centers in Daegu and 11.3% of centers in Gyeongbuk area were equipped with a hot holding table(p<0.05). Overall, there is a need for education of foodservice to managers because most facilities do not have dietitians. In addition, facilities and equipment should be supplied continuously to foodservice facilities in community child centers.

  • What this research aims are as follows. First, it aims to examine the difference in gender ratio of single men and women in the entire nation and Gyeongbuk area, and also the ratio of single men in marriageable age in Gyeongbuk area by si, gun, dong, eub, and myeon, Second, the social-economical characteristics of single men in marriageable age in Gyeongbuk area, and third, the causes of problems related to marriage for single men and the solutions. As a result, it was revealed that imbalance of current gender ratio in farming area, farm villages falling behind socially and economically, young women evading marriage with young men in farming area, and difficulty of making a girlfriend, all served as the factors that made it difficult for single men to get married. It is impossible to overcome these factors by individual efforts made by single men in farming area. Therefore, these problems would be resolved by taking such measures as construction of social infrastructure in farming area in Gyeongbuk area, enhancement of status of women in farming area, and enhancement of awareness for men in farming area.

  • This study was conducted to evaluate the food habits and nutrient intake of preschool children by investigating their food and snack consumption. To accomplish this, a food habit questionnaire and dietary intake survey was administered to 148 children between 2 and 6 years of age (average 4.8 years). According to the Kaup index, the underweight, normal, overweight and obesity levels of the subjects were 4.7, 60.1, 26.4, and 8.8%, respectively. In addition, the total energy intake met the EAR ($1433.94{\pm}369.70kcal$), whereas the protein, iron, phosphorus, vitamin B and vitamin C levels exceeded the EAR and the RI. Furthermore, the nutrient intake profile revealed that the mean caloric value of breakfasts consumed by preschool children in Daegu (403 kcal) was significantly (p<0.001) higher than that of preschool children in the Gyeongbuk area (271 kcal). Additionally, preschool children in Daegu ($382.96{\pm}255.79kcal$) usually consumed significantly (p<0.01) less food than those in the Gyeongbuk area ($413.82{\pm}275.43kcal$). The preferred snacks among subjects (in descending order) were milk, bread, fruit, potato or sweet potato and cookies. The mean score of the Food Habit was $3.72{\pm}0.35$ out of 5, although the score of preschool children in Daegu ($3.77{\pm}0.32$) was significantly (p<0.05) higher than that of children in the Gyeongbuk area ($3.65{\pm}0.32$). Taken together, these results indicate that there were significant differences in the Food Habit and nutrient intake level of children in Daegu and the Gyeongbuk area. Therefore, parents and caregivers should be aware of the importance of the nutritional status of preschool children and choose healthy snacks for them.
