콜센터 성과평가 및 인적자원 관리는 상담원의 개인적, 사회적 특성을 고려하지 않고 해결 콜 수에만 의존적으로 평가되고 있다. 그러나 콜센터는 대부분 업무가 고객과의 공동 문제해결에 기반하고 있어 상담원의 개인적 역량 및 사회적 역량이 업무성과에 직접적인 영향을 미친다. 따라서 본 연구는 콜센터 상담원을 대상으로 개인적 역량 및 조직 내 사회적 특성이 업무 성과에 미치는 영향을 분석함으로써 콜센터 성과평가 및 상담원의 채용관리에 도움을 주고자 한다. 이를 위해 본 연구는 RGT를 이용하여 개인적 특성을 도출하였고, 네트워크 분석을 통해 사회적 관계를 분석하였다. RGT와 네트워크 분석을 통해 도출된 변수를 바탕으로 회수실적과의 상관계수가 높은 항목을 선정한 후 회귀 분석을 실시하였다. 실험 결과, 회식망 내향 중앙성, 업무 적극성, 개방적 성향, 배우는 것을 즐기는 성향의 네 가지 특성이 회수실적에 유의미한 영향을 미치는 것으로 나타났다. 본 연구 결과는 콜센터 상담원 성과평가 뿐 아니라 상담원의 채용 및 관리에도 의미있는 정보를 제공할 수 있을 것으로 기대된다. Current performance evaluation of call center employees is dependent on the number of calls they have resolved, regardless of the individual and social characteristics of employees. However, since call center tasks are highly customer-oriented and emotional laborious, individual capability as well as social characteristics of employees is critical to performance. Therefore, this study analyzed the relationship between employees" individual/social characteristics and their performance. To extract individual characteristics, a repertory grid technique was employed, whereas social network analysis was conducted to extract the social characteristics of employees. Using individual and social characteristics as input variables, multiple regression was conducted to analyze the effect of each variable on performance. As a result, in-degree centrality of dining network, initiative characteristics, open characteristics, and enjoyment of studying were determined to be important variables for performance. This study is expected to be used in both performance management and human resource management of call center practices.

This paper proposes a low-supply voltage CMOS voltage reference circuit considering the tolerance of process variations. It uses a self_biasing current source and compensation circuit for tolerance of process variations. T.C. of 475ppm/℃ from -25℃ to 85℃, PSRR of 42㏈ at 1.8V±10% supply voltage are measured by SPECTRE simulation in a 0.18㎛ CMOS process. Also Vref voltage has 3.5%~4% variation for 10% process variations of resistor.

The vulcanizate structure of silica-filled compounds is affected by the filler-rubber interaction (FRI) due to the silica-rubber coupling reaction and the chemical crosslink density (CCD) of the matrix rubber. In this study, the vulcanizate structure changes of silica-filled compounds according to the silane and sulfur variation were quantitatively analyzed using the Flory-Rehner and Kraus equations. In efficiency vulcanization (EV) conditions with low sulfur content, FRI increased when the bis-[3-(triethoxysilyl)propyl]tetrasulfide (TESPT) content increased, and the CCD clearly decreased. By contrast, in semi-EV conditions with high sulfur content, as TESPT content increased, the FRI increased the same way EV conditions, but the CCD was unchanged. Based on these results, it was confirmed that FRI of the silica-filled compounds increased as TESPT content increased, but CCD decreased or retained similar values according to the vulcanization system, indicating that the formation reaction of FRI was preferred over CCD.

A phytoene synthase gene, crtB, was isolated from Kocuria gwangalliensis. The crtB with 1,092 bp full-length has a coding sequence of 948 bp and encodes a 316-amino-acids protein. The deduced amino acid sequence showed a 70.9% identity with a putative phytoene synthase from K. rhizophila. An expression plasmid, pCcrtB, containing the crtB gene was constructed, and E. coli cells containing this plasmid produced the recombinant protein of approximately 34kDa , corresponding to the molecular mass of phytoene synthase. Biosynthesis of lycopene was confirmed when the plasmid pCcrtB was co-transformed into E. coli containing pRScrtEI carrying the crtE and crtI genes encoding lycopene biosynthetic pathway enzymes. The results obtained from this study will provide a base of knowledge about the phytoene synthase of K. gwangalliensis and can be applied to the production of carotenoids in a non-carotenoidproducing host.

The purpose of this study is to provide information for the manufacturer of shoes. The data was collected through a questionnaire on purchasing practices, wearing state and overall satisfaction with shoes for high school students. The questionnaire survey was conducted on 598 high school students(49.2% male students, 50.8% female students) in the Cheongju area. Statistical tests such as frequencies, percentages, and crosstabs were conducted to analyze the data. The results were as follows: 1) The main reasons for buying new shoes were replacing worn out shoes or color and design coordination with other apparel. 2) Male students bought shoes generally from shoe stores and sports brand retailers, but female students bought mainly from shoe stores. The order of criteria considered for purchasing was design, size, price, color, style coordination and comfort. 3) While attending school, male students generally wore sports shoes, but female students wore sports shoes and dress shoes by similar ratio. 4) The male student used primarily ordinary sports shoes and casual shoes secondarily, and for female students, primarily ordinary sports shoes and sneakers secondarily. 5) They were satisfied with shoe design and color but quality of the material and durability were unsatisfactory. 6) When they wore shoes for long hours, they experienced fatigue of the whole leg and general discomfort, blisters on the feet, and red skin.

네트워크 기반 오용 탐지 시스템은 이미 알려진 공격기법만 탐지할 수 있기 때문에 새로운 공격에 대한 탐지를 하기 위해서는 수시로 새로운 침입패턴을 추가시켜야 하는 어려움이 있다. 본 논문에서는 이런 어려움을 해결하기 위해 네트워크 데이터를 분석하여 새로운 침입패턴을 생성해 내는 자동화 시스템과 제안된 시스템의 성능을 결정짓는 밀도 함수 기반의 아웃라이어 탐지 알고리즘을 제안한다. 알고리즘의 성능 평가는 정확도, 재현율을 결합한 조화평균의 측정값을 이용하여 사용하여 평가했으며 기존 알고리즘보다 성능이 향상되었음을 보인다.
