본 연구에서는 HRGC/HRMS에 의한 다이옥신분석에 있어 가장 널리 사용되고 있는 SP-2331 및 DB-5MS 컬럼에 의한 독성 2,3,7,8-다이옥신 동족체 분리의 영향에 대하여 조사하였다. 컬럼분리성능평가 표준용액과 비산재 시료의 분석을 통하여 이들 컬럼에 의한 tetra, penta 및 hexa-2,3,7,8-동족체의 분리에 대한 부분과 I-TEQ값의 영향을 중심으로 설명하였다. 이들 두 컬럼에 의한 분석에서 컬럼분리성능평가 표준용액의 경우 DB-5MS에 의해서는 총 2,3,7,8-치환이성체의 농도는 508.4 ng/mL로 나타났으며, SP-2331에 의해서는 515.8 ng/mL로 나타났다. 이들을 I-TEQ값으로 환산하였을 때 거의 동등하게 나타났다. 비산재 시료의 경우에서도 이들 두 컬럼에 의한 2,3,7,8-치환이성체의 총 농도와 I-TEQ값이 거의 비슷하게 나타났다.

This study was conducted to evaluate growth performance of weaned pigs using diets based on ideal protein of the Korea swine feeding standard (KFS) and US the nutrient requirements of swine (NRC). A total of 96 weaned (initial body weight of 6.12 ± 1.21 kg) pigs were randomly allocated into 2 dietary groups with 12 pens per diet (4 pigs·pen-1) in a completely randomized design. The dietary treatments were corn and soybean meal-based diets formulated by the KFS and NRC nutrient requirements estimates for weaned pigs. Experimental diets were fed for 6 weeks in 2 phases feeding program based on age: 1) Phase 1 = week 1 to 3 (21 days); 2) Phase 2 = week 4 to 6 (21 days). During Phase 1 and 2, there were no differences (p > 0.05) for the initial and final body weights between the KFS and NRC groups. Additionally, the average daily gain (ADG), average daily feed intake (ADFI), and gain to feed ratio (G : F) during overall experimental period were not different between the groups. In conclusion, weaned pigs fed the diet based on the KFS had a similar body weight and growth performance to those fed the diet based on the NRC. This suggests that the Korea swine feeding standard may be used for the diet formula of weaned pigs in Korea swine production compared with the US nutrient requirements of swine.

This study compares the growth performance(weight-for-age Z-score, height-for-age Z-score, weight-for-height Z-score) of one- to three- month-old Korean infants(n=232) with the Korean standard(1994) and NCHS reference(1983). The weight-for-age Z-scores(WAZ) by the Korean standard were -2∼1,5 for males and -3∼1 for females. The NCHS reference, WAZ results were -1∼2.5 and -2.5∼3.5 for males and females, respectively. The WAZ compared Korean standard showed no subjects with overnutrition. But 1.3% of the infants showed signs of malnutrition. Comparison with NCHS reference revealed that 0.4% of the infants were malnourished and 7.0% of the infants were overnourished. The WAZ of formula-fed infants were distributed higher than breast-fed infants, but that was not significant. The height-for-age Z-score(HAZ) by the Korean standard were -4.5%∼1.5% for males and -4∼1.5% for females. According to the NCHS reference, HAZ were -2.5%∼2.5% and -3∼3 for males and females, respectively. When the WAZ was compared with the Korean standard, there was no overnutrition but 16% of the infants showed signs of malnutrition. The NCHS reference, revealed that 6.9% of the infants were malnourished and 1.8% of the infants were ovemourished. The weight-for-height Z-scores(WHZ) by the Korean standard were -2∼5 for males and -2.5∼5 for females. The NCHS reference WAZ scores were -1∼4 and -1.5∼4.5 for males and females, respectively. When the WHZ was compared with the Korean standard, 2.2% of infants were malnourished and 19.5% were overnourished. There were no malnourished subjects according to the NCHS reference and 19.1% of the infants were overnourished. When the three Z-scores are considered together, 92.0% of the infants should a normal growth status, there was no malnutrition, and 8.0% of the infants were overnourished. The growth performance was evaluated differently according to the type of standards. Thus, it is necessary to set proper growth standards for infants, according to which classification of feeding methods is chosen. A longterm and careful assessment of infants's growth performances to develop any group of standards.

본 논문에서는 GNSS-RTK 정확도에 근거한 측량기기 성능 기준 마련의 당위성 제기와 국제표준을 적용한 정확도 성능검사 방안 모색하기 위해 「ISO 17123-8」에 의한 현장시험 절차와 방법을 고찰하고 이 표준을 적용한 관측실험을 수행하였다. ISO 표준에 따라 간이시험과 완전시험 절차를 적용해 5개 기종 GNSS 수신기가 RTK 방식으로 취득한 수평·높이 좌표가 기준정확도 이상이 되는지와 이들 좌표 정확도의 동등 여부를 통계검정 하였다. 그 결과 동일 등급 GNSS 수신기라 할지라도 RTK 정확도가 통계적으로 차이가 있을 수 있고 상이한 등급 수신기들도 그 정확도는 동등할 수 있는 것으로 나타났다. 이로부터 본 연구에서는 GNSS 상시관측 인프라의 고도화로 급증하는 실시간 측량 수요 대처 및 새로운 형태와 특징을 갖는 GNSS 수신기 활용성 제고를 위해 RTK 정확도 기반 측량기기 성능 기준 마련과 검사 방법의 도입 필요성을 제기하였다. 여기서, GNSS-RTK 정확도 평가에는 「ISO 17123-8」 따른 관측 시험 중 완전시험법의 두 분산의 비를 비교해 시험정확도가 기준정확도 이상임을 검사하는 방법이 적합한 것으로 판단하였다.

Objectives : In this paper, we proposed a method to comprehensively examine the roles of medical insurance review nurses' by analyses of task importance and task performance. Methods : For the analyses, we used the responsesof 268 nurses who completed a questionnaire for members of the Medical Insurance Review Nurses Association in 2015, and analyzed task importance and task performance using the IPA method and the standard task guide. Results : There were significant differences in task importance and task performance according to task position. In the category of 'Keep up the good work,' 'Calculate benefit standard' was indicated only in administrative positions, and in the category of 'Concentrate here,' 'Manage hospital resources' and 'Process after appeal results' was demonstrated only in general positions. There were differences in the 'Low priority' and 'Possible overkill' categories by task performance according to task position. Conclusions : Our results indicate the necessity of a new education system and task reassignment according to task importance and task performance as perceived by medical insurance review nurses.

This study was to examine the differences in the levels of etiquette consciousness and performance of adolescents according to individual variables (sex, school, and self-esteem), family-related variables (parents' age and education level, and subjectively perceived living standard), and. etiquette-related variables (communication on etiquette, experience of etiquette education, parents' interest of and necessity. of etiquette education). The subjects were 394 middle and high school students in Jeonju. Such statistictical methods as t-test, F-test, Pearson's correlation analysis, and stepwise regression analysis were performed for this research. Results showed that the levels of etiquette consciousness and performance were slightly high. Among the domains of etiquette consciousness and performance, the levels of bowing manner and public etiquette were found to be relatively high. The etiquette consciousness and performance were different. according to adolescents' self-esteem, subjective living standard, and such etiquette variables as communication on etiquette, experience of etiquette education, parent's interest and necessity of etiquette education. Communication on etiquette was the most powerful variable influencing adolescents' etiquette performance. The results implied that the etiquette education need to be performed both in family and in school.

본 논문에서, 우리는 다수의 짧은 주기들을 추가함으서 LDPC 부호의 성능을 향상시킨다. 짧은 주기, 특히 길이가 4인 주기는 만약 표준 BP 복호가 쓰인다면 LDPC 부호의 성능을 저하시킨다. 그래서 현재의 연구들은 성능 높은 LDPC 부호를 설계하기 위하여 길이가 4인 주기들을 없애는데 초점을 맞추고 있다. 우리는 만약 수정된 BP 복호를 사용하면 다수의 길이가 4인 주기들은 LDPC 부호의 성능을 향상 시키는 것을 발견했다. 본 논문에서는 다수의 짧은 주기들을 가진 LDPC 부호를 위한 수정된 BP 복호 알고리즘이 소개되고 또한 다수의 짧은 주기들을 가지는 LDPC 부호의 수정된 BP 복호성능이 짧은 주기를 가지지 않는 LDPC 부호의 표준 BP 복호 성능보다 우수함을 보였다.

침입방지시스템은 네트워크에서 공격 서명을 찾아내어 자동으로 조치를 취하여 비정상적인 트래픽을 중단시키는 보안시스템이다. 수동적인 방어를 하는 침입차단시스템이나 침입탐지시스템과 달리 침입경고 이전에 침입을 중단시키는 개념의 솔루션이다. 침입방지시스템의 보안성 성능은 보안감사, 사용자 데이터 보호, 보안 인증 등에 좌우되며 성능은 탐지시간, 처리량, 공격차단 성능 등에 좌우된다. 본 연구에서는 이러한 침입방지시스템의 보안성 성능평가를 위한 모델을 구축하기 위해 CC(Common Criteria : ISO/IEC 15408)와 소프트웨어 제품평가에 관한 ISO 국제표준을 근간으로 하여 융합 성능평가 모델을 구성하였다.

This study analyzes the management performance of environmentally-friendly rice farms using GCM method based on the multifaceted approach. This approach compares the management performance of GCM farms before and after the introduction of GCM, as well as the performance of GCM farms with the performance of conventional farms. It also compares the technical and managerial competence level of surveyed GCM farms with that of conventional farms based on the standard diagnosis table developed by Rural Development Adminstration. Results showed that average income has increased after the introduction of the GCM method and the average income of GCM farms was higher than that of conventional farms, while the level of rice production in farms using GCM method was lower than that of conventional farms. In addition, the technical and managerial competence score of surveyed farms using GCM method was higher than that of conventional farms. These results implies that the higher management performance of GCM farms compared to the conventional farms is attributed to not only the GCM method but also the competence level of farms using GCM method.
