무선센서네트워크에서 저가의 센서 필드를 구성하기 위해 센서노드의 위치 추정은 매우 중요하다. 소수의 위치를 알고 있는 센서노드인 앵커노드를 이용하여 모든 일반노드들의 위치를 알게 하는 방법으로 DRLS이 있으며, 이 기법은 이전의 기법들에 비해 상대적으로 정확한 위치 추정을 가능하게 한다. 하지만 DRLS는 이웃하는 앵커노드가 없는 일반노드의 경우 위치 추정 정확도를 심각하게 낮추는 에러 전파가 일어나는 문제점이 있다. 본 논문은 DRLS의 에러전파를 줄이기 위한 Distributed Localization for Reducing Error Propagation (DLREP)를 제안한다. DLREP는 각 일반노드들이 DRLS를 이용하여 위치 추정을 한 뒤 한 번의 추가적인 브로드캐스트를 더 수행하여 각 일반노드가 추가적인 앵커노드의 위치 정보를 얻게 한다. 그리고 이 정보를 이용하여 앵커노드 위치를 중심으로한 초기 위치의 회전을 통해 일반노드의 에러전파가 된 위치에 대한 수정을 가한다. DLREP는 위치 측정이 완료된 DRLS에 적용되어 더 정확한 센서노드의 위치 추정을 할 수 있도록 하는 진보된 위치 추정 기법이다.

The purpose of this study is a descriptive research study to understand the relationship between sexual attitude, sexual knowledge and gender sensitivity of general college students, and to analyze the effect on gender sensitivity. Participants included 139 general college students. Data collection was conducted through self-reported questionnaires. Data were analyzed using descriptive statistics, t-test, ANOVA and Schffe test for multiple comparisons. The average score of the general college students sexual knowledge was 22.73 out of 38 points, and their sexual attitudes scored 2.92 out of 5points. The average score of gender sensitivity was 2.03 out of 5points. As a result of the study, gender sensitivity was positively correlated with sexual attitude (r=.201, p=.018), and the factors affecting gender sensitivity of general college students were sexual attitude (𝛽=.196, p=.021), and the explanatory power of these factors was 34.0%. Based on the results of this study, it is thought that it is necessary to development of a program that can establish a correct sexual attitude in order to increase the gender sensitivity of general college students.

The purpose of this study is to investigate the differences of perception on giftedness between homeroom teachers and teachers of the gifted. The data was collected from 13 homeroom teachers and 8 teachers of gifted students. It was analyzed using recommendation letters, and shorthand notes about giftedness. The results of the study were as follows: most homeroom teachers used awards, learning attitude, presentation of self and school achievements for defined giftedness and preferred an exemplary student with task commitment but often overlooked motivation. The teachers of the gifted preferred motivation and self-satisfaction but not other social and affective characteristics. Also homeroom teachers thought that education condition is important, while the teachers of the gifted believed it was not an all important element. These differences will hurt the credibility in the selection or gifted students because homeroom teachers and teachers of the gifted use different words and expressions in their assessments of the same students. Therefore, I believe more needs to be done to encourage homeroom teachers to better understand gifted children through training programs.

The purpose of this study is to examine the effect of service quality of banks on customer satisfaction and recommendation intention through empirical analysis. In particular, the focus was on the differences of the causal effect between PB(Private Banking) customers and regular customers. For this study, two groups were surveyed and 428 valid questionnaires were analyzed. The hypothesis was tested with a structural equation model using AMOS 23.0. As a result, empathy, reliability and tangibles of bank service quality had a positive(+) effect on customer satisfaction. However, responsiveness and assurance were not statistically significant. On the other hand, customer satisfaction has a positive effect on recommendation intention. This study was conducted to compare the two groups, PB customers and regular customers, and found a significant difference. In the PB customers group, tangibles had a positive effect on customer satisfaction, but no other factors were supported. On the other hand, in the regular customers group, empathy and reliability had a positive effect on customer satisfaction while responsiveness, assurance, and tangibles were not supported. Customer satisfaction were analyzed to have a positive influence on recommendation intention in both groups. These findings are academically significant by applying the SERVQUAL factors to banking services and revealing the differences between the PB customers and regular customers. In practice, it is meaningful in that it provided banks with the insights needed for future segmentation and management of customer groups.

The characteristics of hydration and hot-water solublilization of milled rice during cooking were investigated using Korean rice [3 varieties of Japonica type and 3 varieties of Tongil type (Japonica-Indica breeding type)]. The water uptake rate constants of Japonica type varieties during cooking were later than those of Tongil type varieties. The contents of solubles and soluble amylose among Japonica type varieties during cooking were similar, but those among Tongil type varieties were different. At the same cooking conditions, Japonica type varieties showed higher contents and leaching rate constants of solubles as well as soluble amylose than Tongil type varieties.

In this study, antioxidant activities, proximate composition, and physicochemical characteristics of tetraploid 'Etteum' variety in Platycodon grandiflorum (SD) were evaluated and compared with those of a domestic diploid variety in P. grandiflorum (ND). Moisture content, crude fat, crude fiber, and crude ash contents were higher in ND, whereas crude protein and carbohydrate content were higher in SD. The amount of crude saponin in SD (2.01%) was higher than that in ND (0.88%). The reducing sugar contents of ND and SD were 3.09% and 2.82%, respectively (P<0.05). The pH level was lower in the ND (ND, 4.98; SD, 5.68). Acidity was 2.74% in ND and 2.34% in SD. Under the Hunter color system, redness was lower and lightness/yellowness higher in SD compared to those in ND. Total phenol contents of ND and SD were 0.100 mg/mL and 0.227 mg/mL, respectively. Antioxidant activities based on 1,1-diphenyl-2-picrylhydrazyl scavenging activity and SOD-like activity of SD were higher than those in ND. Based on these results, SD is a good candidate for food processing in terms of its physicochemical and antioxidative activities.
