  • CuInGa 전구체를 여러 분위기에서 급속 열처리 공정 (rapid thermal processing; RTP)을 이용하여 셀렌화하여 CuInGaSe 박막을 제작하였다. 공정조건은 각각 진공상태, 아르곤 가스 유동 상압상태, 아르곤 분위기 상압밀폐에서 덮개 유리를 사용한 상태 및 아르곤 밀폐상압에서 추가로 Se을 공급한 상태이었다. 제작된 CuInGaSe의 특성을 ICP 측정을 통하여 분석하였다. 열처리 조건에서 시스템이 밀폐상태에 가까울수록 Se 증기압이 높을수록 CuInGaSe 박막의 Se 함량이 증가하였다. 아르곤 분위기 상압 밀폐상태에서 제작된 CuInGaSe 박막을 이용하여 제작한 태양전지의 효율은 9.6%이었다.

  • The objective of this study is to investigate a priority and selection of agricultural specialization items from Daegu and Gyeongbuk region by using analytical tools such as, the Analytic Hierarchy Process(AHP) and the Scoring Method. The results of this study are as follows; 1) Five major items were selected for each region based on Daegu and Gyeongbuk regional agricultural performances. 2) The results of AHP analysis, Daegu and Gyeongbuk's agricultural experts evaluated the weight of three decision-elements(objectiveness 0.35, efficiency 0.341, identity 0.309) and seven decision-elements. 3) Results of AHP and Scoring Method analysis, Investigated a priority of agricultural specialization 3 items in 25 cities and districts Daegu and Gyeongbuk regional agricultural performances. 4) Finally, The results of this study will provide basic information on agricultural specialization policy in Daegu and Gyeongbuk region.

  • This study was conducted to investigate the changes in patterns of Daegu- and Gyeongbuk-based patients' use of medical care facilities located in Seoul. The 'Patient Survey' data issued by the Ministry of Health and Welfare for 2002, 2005, and 2008 were used. Among all discharged patients residing in Daegu and Gyeongbuk, 133,456 who used medical facilities in Daegu, Gyeongbuk, and Seoul were selected. Among patients residing in Daegu, 2.2% used medical facilities in Seoul in 2002, 3.7% in 2005, and 3.5% in 2008. The corresponding rates among patients living in Gyeongbuk were 5.6%(2002), 7.1%(2005), and 7.3%(2008). Regarding the ICD-10 disease groups, the use of medical facilities in Seoul by patients residing in either Daegu or Gyeongbuk increased in 2005 right after the introduction of the KTX high-speed train service, covering various disease groups, but decreased again in 2008. 'Neoplasm' cases, however, showed a progressive rising trend during the years studied. Multivariate data analysis for the three years showed that sex, age, payment type, hospital type, residence, year, and disease groups were all significantly associated with the utilization of medical facilities in Seoul. The major results are : First, use of medical facilities in Seoul by Gyeongbuk patients was 2.4-fold higher than that by Daegu patients, but with respect to 2005 and 2008 vs. 2002, use of medical facilities in Seoul by Daegu resident patients' showed a larger increase than that by Gyeongbuk's patients. Second, for patients residing in the two regions, use of medical facilities in Seoul was highest for 'congenital malformations, deformations and chromosomal abnormalities', followed by 'neoplasms'. Third, for patients residing in the two regions, general hospitals comprise the primary factor in the use of medical facilities in Seoul. The study shows that local medical facilities should individually exert more efforts to improve the quality of their medical services. Relevant authorities should likewise help these facilities develop their own unique services and respective specialization.

  • In this study, the accuracy of the orthognathic surgical guides with single-stage split path was upgraded to realize orthognathic surgical guides with two-stage split path and simulated surgery was performed to verify its accuracy. As a result, the average error distance between the simulation model and the scan model was + 0.289 / - 0.468 mm (standard deviation 0.128), which was confirmed to be within ± 0.5 mm, which is a clinically acceptable level. Also, there was no significant difference compared with the average value of + 0.313 / - 0.456 mm (average standard deviation 0.106) of the conventional single-stage split path type device. It is judged that the use of this device can contribute to the reduction of surgical time and increase in accuracy since a separate finishing operation for bone preparation is unnecessary.

  • The purpose of the present study was to evaluate the characteristics of nutrient intakes of adults aged 20-64 years in Daegu and Gyeongbuk areas in comparison with Seoul and the whole nation. Data from the 1st (1998) to 3rd (2005) Korean National Health and Nutrition Examination Survey (KNHANES) were used. Total numbers of subjects were 296-369 from Daegu and 307-447 from Gyeongbuk while 1076-1244 from Seoul and 5436-6852 from the whole nation. Average energy intakes (men; 2,386, 2,581, 2,305 Kcal, women; 1,937, 1,981, 1,804 Kcal in 1998, 2001, 2005, respectively) of the subjects from Daegu were higher than those from Gyeongbuk (men; 2309, 2267, 2487 Kcal, women; 1,851, 1,845, 1,901 Kcal) and those from Seoul in 1998 and 2001 but not different from those in 2005. Energy from carbohydrate was consistently higher in the subjects from Daegu and Gyeongbuk than in those from Seoul from 1998 to 2005, when the subjects whose carbohydrate energy was over 70% comprised 34 to 58% of the total in the two regions. In 2005, the average intakes of calcium of women and men from Daegu were 512 and 573 mg, iron, 12.8 and 16.6 mg, sodium, 4,650 and 5,951 mg, potassium, 2,585 and 3,152 mg, vitamin A, 823 and 1,038 ${\mu}$gRE, thiamin, 1.10 and 1.43 mg, riboflavin, 1.08 and 1.33 mg, and niacin. 15.4 and 19.3 mg, and vitamin C, 94 and 105 mg and these intakes were not very different from those from Gyeongbuk except higher sodium intake of the Gyeongbuk subjects. Nutrients of which the intakes were over 50% lower than EAR were calcium and riboflavin and those about 30% lower than EAR were iron in women, vitamins A and C in men and women from Daegu and Gyeongbuk. From the present results, it is concluded that high dependence on carbohydrate as energy source and low calcium intake in adults of Daegu and Gyeongbuk are serious and that low intakes of riboflavin, iron and vitamins A and C need to be improved. But changes in the intakes of total energy and other micronutrients from 1998 to 2005 were not reliable enough to judge the regional nutrition due to large variations during this period. The present study also provides the adults' nutrient intakes separated by sex and age groups in the three regions which could be readily used for setting up the nutrition policy for the adults in the regions.
