The aim of this present study was to investigate the impact of different seeding rate and nitrogen fertilizing levels on the seed yield and feed value of oats(Avena sativa L.) grown in Gyeongbuk area for two years. The experiment was arranged in split plot design with 3 main plots(100, 130 and 160 kg of seed/ha) and 4 subplots(0, 50, 70 and 90 kg N/ha), with 3 replicates. Heading, flowering, and maturing dates of oats sown in spring 2017, delayed by two days compared to that of spring 2016, and the plant height of spring 2017 were significantly shorter than that of spring 2016(18.1 ~ 23.4 cm). In addition, the highest number of stems and number of panicles according to different seeding rate and nitrogen fertilizing levels were achieved with the seeding rate of 160 kg/ha and 90 kg of N/ha in 2016 and 2017, respectively. In case of seed yield as affected by different seeding rate, the highest seed yield was achieved with a seeding rate of 130 kg/ha(p<0.05), and based on nitrogen fertilizing levels, the highest yield was obtained in 50 kg of N/ha compared to others. The crude fiber(CF), neutral detergent fiber(NDF) and total digestible nutrients(TDN) of oats cultivated and harvested in spring 2016 and 2017 according to different sowing rate were the highest in the seeding rate of 130 kg/ha. The crude protein(CP) content and total digestible nutrients(TDN) of 2016-2017 as influenced by nitrogen fertilizer levels were the highest in the nitrogen fertilizer level of 90 and 50 kg N/ha, respectively. In conclusion, the proper seeding rate and the optimal nitrogen fertilizing level in Gyeongju, Gyeongbuk province were considered to be the most appropriate in 130 kg/ha and 50 kg of N/ha, respectively.

The objective of this study was to efficiently produce forage crop seed of spring oat (Avena sativa L., cultivar High Speed) in Gyeongbuk area. Forage crop oats (130 kg/ha) were sown with a randomized block design. They were sown in triplicates in 2015 and 2016 using basal fertilizer of 70 kg N, 74 kg P, and 39 kg K/ha. Agronomic traits and seed production of oats were investigated to determine the influence of seeding dates (February 28/29th, March 10th, and March 20th). Heading, flowering, and maturing dates of these oats sown on February 28/29th and March 10th were almost close to each other with 1-2 days of difference for all test plots. For oats sown on the last day (28/29) of Feb., plant heights (111.6-122.6 cm) were significantly longer than those sown in March each year. In addition, panicle number (416.7 per m2) and panicle length (17.3 cm) of oats sown on the last day of February were also significantly (p < 0.05) larger than those of oats sown in March in 2015 and 2016, respectively. Based on these results, it is recommended to sow these oats on the last day of February to have better agronomic traits in terms of plant height, stem length, panicle length, and panicle number per m2. Grain numbers (56.3 and 63.3) and kernel weights (1.72 and 2.00 g) per spike in plots of oats sown on the last day of February were also significantly (p < 0.05) larger than those of oats in other plots in 2016 and in the average of 2015~2016, respectively. The highest grain yield (6,243 kg/ha) was obtained when oats were sown on the last day of February. Feed value of harvested oats was good in terms of proximate compositions including fiber contents and TDN contents. In conclusion, sowing on the last day of February is the most effective way to increase seed production of spring oats in Gyeongbuk area of Korea.

To study the historical transition of traditional Dasik, analysis of 11 cooking books from the 1400’s to 1800’s was carried out. Jong-Ga was made using Dasik and main ingredients were Songhwa, Kka and Kong Dasik. Special Dasik was in nine of Jong-Ga (Ipjae’s head family of Pungyang Jo’s clan, Sojea head family Gwangju No’s clan, Sawoodang head family Uiseong Kim’s clan, Heobaekdang’s head family of Bukye Hong’s clan, Taechon’s head family of Gyeseong Go’s clan, Gwiam’s head family of Gwangju Lee’s clan, Songdang’s head family of Milyang Park’s clan, Haeweol's head family of Pyeonghae Hwang's clan, Galyam's head family of Jaeryoung Lee’s clan) and Dasik are Gamphi dasik, Heukimja dasik, Baksulgi dasik, Tibap dasik, Daechu dasik, Yukpo dasik, Misutgaru dasik, Dotori dasik and Omija Dasik. It was used as a ritual food and reception food for guests. These recipes are good examples of functional and modern of Korean food. In the future, Dasik as well as discovery of ingredients in other foods of Jong-Ga are needed.

Relationship between lipid intake and obesity has been well-addressed but recent findings indicated that the type of lipid or composition of lipid in the diet also contributes to body fat accumulation and consequential health outcome. The purpose of this study was to investigate the status of nutrition intake including fatty acids, lipids and lipid soluble nutrients between the obese and lean college students and to analyze the relationship between the intake of certain fatty acids and body fat accumulation. Anthropometric elements including body weight, height, body fat and composition were measured, and dietary recall was conducted on a total of 114 college students. Data showed that total calorie intake and total lipid intake were not significantly different between the obese and lean subjects, in both male and female students. However, male obese subjects ate more amount of plant lipids and palmitic acids (C16:0) from their diet (p<0.05), while female obese subjects consumed more linoleic acids (18:2) and linolenic acids (C18:3) compared to normal subjects (p<0.01). Correlation analysis revealed that the consumption of palmitoleic acid (C16:1) and lipid soluble vitamin D were negatively (p<0.05) correlated with body fat accumulation in all subjects and these findings were supported by simple linear regression analyses for those variables. These results implicate that rather than only considering the amount of lipids, suggesting a proper type of lipids or lipid metabolites can be considered in nutrition counseling or education.

As S. Korea is becoming an “aged society”, workers in the country would be exposed to higher risk of workplace injuries due to their reducing work abilities as they are getting old. To identify the relationship between the work ability and the incident rate of workplace injuries, the work ability index (WAI) scores were surveyed from 409 workers occupied in different manufacturing industries reside on north GyoengBuk area. The workplace injury statistics in the year of 2010 for the corresponding industries were analyzed and summarized with the WAI scores by age groups, years of service, and sizes of business. The results showed the WAI scores of the workers occupied in the higher risk of workplace injury was lower than that of the workers of the lower risk. It means the lower the WAI score, the higher the chance of being injured during the task. It is concluded that appropriate correlation exists between the WAI scores of workers and the incident rate of workplace injury. It is recommended to administrate individual work abilities of aged workers in order to keep low rate of workplace injuries in upcoming aged and highly aged society.

본 연구는 경북지역에 근로하고 있는 장애인의 직무만족을 알아보기 위해 자기기입식 및 면접을 통해 설문지를 작성하였고, 연구결과는 다음과 같다. 첫째, 장애인근로자의 직무관련요인에 대한 만족 수준은 대체로 양호(M=3.56)하게 나타났다. 둘째, 장애인근로자의 감독관련 요인에 대한 만족수준을 향상하기 위해 직무수행에 대한 자율성과 권한을 부여함으로서 장애인근로자의 감독관련 요인에 대한 만족수준을 향상할 수 있을 것으로 보인다. 셋째, 장애인근로자의 보수관련요인에 대한 만족수준은 양호(M=3.327)한 것으로 나타났다. 넷째, 장애인근로자의 승진 관련요인에 대한 만족수준을 높이기 위해서는 장애인근로자들의 승진을 위한 직급제를 도입하여 장애인들이 열심히 일하면 승진할 수 있다는 동기부여를 해줄 필요가 있을 것으로 판단된다. 여섯째, 장애인근로자의 동료관련 요인에 대한 만족수준을 높이기 위해서 동료들이 서로 간에 칭찬과 격려를 해 주는 프로그램을 운영할 필요가 있겠다. 일곱째, 장애인근로자의 이직관련 요인에 대한 만족수준은 낮은 수준으로 조사되었으나, 사회통합을 위한 일반사업체로의 전환을 염두에 두고 있는 사람이 적거나, 장애인근로자가 이용할 다른 시설이 부족하기 때문에 현 시설에 계속 다니는 것이 나을 것이라고 생각하는 것으로 판단된다.

This study was performed to investigate the characteristics of indoor air quality (IAQ) in elementary and middle schools in Gyeongbuk area from July to November 2006 . The measurements of indoor air pollutants were made to cover such components as PM-10, CO2, CO, NO2, O3, HCHO, TVOC, TBC, and Radon from school classrooms. The results of this study can be summarized as follows: all of them were less than IAQ standards of Korea. The mean concentration were measured by 43.0 ㎍/㎥ (PM-10), 745 ppm (CO2), 56.1 ㎍/㎥ (HCHO), 350 CFU/㎥ (TBC), 0.026 ppm (O3), 0.6 ppm (CO), and 59.2 ㎍/㎥ (TVOC). Radon was not detected in all surveyed classrooms. The I/O ratio of PM-10 was 0.8∼1.4, while that for HCHO was 5.7∼9.0. Therefore, it was concluded that the indoor pollution of formaldehyde was very serious in classroom.

The objective of this study was to investigate the effects of personal and job characteristics on the organizational commitment and job satisfaction of dietitians employed in different foodservice settings. The subjects were dietitians(n=830) employed by schools, hospitals, and industries in Daegu Gyeongbuk area. A questionnaire was used to determine personal and job characteristics, commitment and satisfaction. Organizational commitment scores were the highest for hospital dietitians, and the lowest for industry dietitians (p<0.05). Industry dietitians felt significantly less loyal to their organizations than did the other dietitians(p<0.05). School and hospital dietitians were significantly more likely to say they cared about the fate of their organizations and thought their organizations were the best to work for. Age, education, length of employment, and wages were positively associated with hospital dietitians' commitment(p<0.05). For all dietitians, the fewer the work hours, the higher the commitment(p<0.05). When asked to rate their satisfaction with various aspects of their jobs, dietitians expressed the most satisfaction with co-workers, and the least satisfaction with promotion opportunities. School dietitians were significantly less satisfied with pay and promotion than were the other dietitians. Organizational commitment was associated with wages(0.05), autonomy(0.08), feedback(0.16), dealings with others(0.07), and task identity(0.09). Job satisfaction was affected by educational level(-0.13), wages(0.10), autonomy(0.18), friendship opportunities(0.14), feedback(0.16), task identity(-0.11) and organizational commitment(0.40) (Lisrel program).

나노물질에 대한 연구와 산업화가 급격히 진행되면서 수환경으로 유출되는 나노물질의 양도 점차 많아지고 있다. 특히 은나노물질의 경우 은의 항균성으로 인하여 다양한 분야에서 사용되고 있으며 환경으로 유출되어 입자상태와 용해된 상태로 존재할 수 있다. 은나노물질과 은이온은 생태환경에 악영향을 줄 수 있으며 미국에서는 2차 먹는물 규제 항목(secondary drinking water standards)으로 정하고 있으며 규제농도는 0.1 mg/L로 정하여 관리하고 있다. 본 연구에서는 경북지역의 지하수와 소규모 먹는 물 공급시설을 대상으로 은의 농도를 측정하였으며 오염 정도를 미국 EPA 기준과 비교하고 시료를 채취한 지역의 특성, 물의 사용 목적 등을 고려하여 분석하였다. 총 293개의 시료 중 EPA의 secondary drinking water standards를 초과한 시료는 2개이며 비율로 0 .6 7%이다. 검출률은 마을 상수도와 소규모 급수시설에서 상대적으로 높으며 농도 기준으로는 지하수에서 상대적으로 높은 농도를 보여 인위적 오염원과 지질적 기원이 동시에 작용한 것으로 판단되었다.

This study was conducted to investigate the effects of mixed-sowing of legume forage and applying of cattle manure on the productivity of organic rye to provide dairy farmers with safe organic feeds. Also the present study aimed to evaluate optimal applying level of cattle manure and carrying capacity of Korean native cattle (Hanwoo) per unit area. The amount of crude protein was significantly higher in the mixed-sowing of legume forage (average 760~786 kg/ha) than in the single-sowing of rye (average 353 kg/ha) (p<0.05). The mixed-sowing of forage peas and the single-sowing of rye tended to improve by increasing the level of nitrous fertilization rather than the fertilization treatment. The amount of crude protein on the rye according to the mixed-sowing of legume was significantly higher in the mixture (average 8.29~9.90%) than in the single (average 4.93%) (p<0.05). The comparison by the level of nitrogen fertilization indicated signifi-cantly high for the rye in 50 kg N/ha than in fertilization treatments (p<0.05). Total digestible nutrients (TDN) amount in the single-sowing of rye was average 46.86% and has lower than average 49.96~50.12% of the mixed-sowing of legume, and especially the mixed-sowing of forage pea was the highest with 54.55% in 150 kg N/ha for the level of nitrogen fertilization (p<0.05). The breeding ability of annual organic livestocks per unit area according to the feed value of rye presented significantly higher ability in the mixed-sowing of legume (3.72~4.12 heads) than the single-sowing of rye (average 2.26 heads) (p<0.05). By summarizing above results, the mixed-sowing of legume is required to improve the productivity and the feed value of rye for increasing organic livestock breeding ability in southern area of Gyeongbuk regions, and the study for identifying the appropriate fertiliza-tion level using livestock excretions is further necessary.

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. Also, 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. The average levels of heavy metal of herbal medicines in Gyeongbuk area are as follows : Mercury is 0.037㎎/㎏, Chromium is 0.093㎎/㎏, Nickel is 0.108㎎/㎏, Copper is 0.475㎎/㎏, Zinc is 3.14㎎/㎏, Manganese is 1.52㎎/㎏, Iron is 7.83㎎/㎏, and Cadmium, Lead and Arsenic is not detected. It was very lower in concentrations than those of average Korea area. 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(0.68㎎/㎏, 1523㎎/kg). Correlation coefficients of 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.
