The purpose of this research is to find out the service quality dimensions and detailed elements of a call center, and to study what relationship the service quality dimensions have with service recovery and customer royalty. This research set up the hypothesis and the research model to verify the relationship between the call center service quality and the service quality customer royalty for 139 people surveyed who experienced dissatisfactions. The result of the hypothesis verification shows that it has an influence on the counselors' service quality and service recovery processes of 3 call centers. The service recovery has en influence on the customer royalty. The result quality as a result remained for a customer after counseling can be called the ultimate purpose of using the call center for a customer, and the research shows that it has the largest influence on the service recovery of 3 dimensions of the call center service quality. In the relationship between the service recovery and the customer royalty, the service recovery has a meaningful influence on the customer royalty.

Recently many local governments have carried out dong merger and abolition process to cope with rapidly changing administrative demand and environment. This administrative effort impacts substantially the locational characteristics of the existing dong offices which directly involve in the quality of local community life. In this paper, we attempt to analyze the location pattern of current dong community service centers (formerly, 'dong office') and suggest the optimal locations maximizing spatial accessibility. As an application, we examine the location pattern of the existing dong community service centers in Mapo-gu, Seoul. Moreover, we compare current spatial configurations with the optimally selected locations such as, a Median maximizing spatial efficiency, a Center maximizing spatial equity, and a Centdian exploring compromising solutions regarding the tradeoff between efficiency and equity. The analytical results present that each of dong community service centers was systematically evaluated in terms of spatial efficiency and equity and in general the community service center locations are not spatially optimized with respect to efficiency and equity, compared with the optimal locations.

'상전벽해(桑田碧海)'다. 과거 한때 미 공군의 폭격 훈련장으로 사용되었다는 용정리 일대. 지금은 우리나라 전력산업 선진화를 위한 각종 첨단 연구개발 설비들로 가득찬 R&D시험장으로 탈바꿈한 고창전력시험센터가 자리하고 있다. 대전력 전송을 위한 환경 친화적이고 경제적인 765kV 기술 국산화를 위해 1989년 착공된 총 부지면적 245,700평 규모의 전력시험센터. 이후 21년이 흐른 현재, 그동안 전력산업 선진화에 필수적인 다양한 시험장 및 설비구축을 통해 도출해낸 첨단 연구시험 성과는 우리나라 전력산업 발전수준을 향상시켜가면서 명징하면서도 괄목할 만한 성과의 궤적을 오늘도 새겨 나가고 있다.

사물인터넷이란 인간의 일상생활에 사용 중인 가전제품, 의료기기, 기타 센서 부착 기기들이 인터넷에 연결되어 스스로 통신하고 제어하는 환경이다. 본 논문에서는 사물인터넷을 구성하는 각 사물들 간의 효율적인 통신을 위해 센터노드를 설정하고 각 사물들이 센터 노드를 중계기로 활용하여 다른 사물들과 효과적인 통신할 때 보로노이 다이어그램을 적용하는 방법을 제안한다.

As the Korean College scholastic Ability Test (CSAT) has been implemented for 17 years since 1994, it is becoming more and more difficult to make new items that haven't been previously used to measure students' thinking ability. Therefore, it is necessary to keep conducting research on making new test items that can measure students' scholastic ability reliably. For this reason, multiple choice items on the Japanese university entrance exam, which is a Japanese National Center Test for University Admissions (NCTUA) equivalent of CSAT, were analyzed in order to draw implications for CSAT item development. In this study, we analyzed the Japanese NCTUA administered in January 2009 to investigate the structure of its science test. We also analyzed the NCTUA items by the domains of contents and behaviors, and tried to predict item difficulty from the perspective of Korean applicants. Major findings are as follows: Most NCTUA items measure understanding knowledge or low level thinking ability. Also the alloted time for each item is longer than CSAT. The number of test items, and the number of choice and alloted points for each item are diverse, unlike CSAT. The number of items using real-life materials are much more, but the items are not rigorous in sentence expression compared to CSAT. And the difference of difficulty level among science tests were larger with reference to CSAT. Also science score is required for most applicants regardless whether they are taking liberal arts or going onto the science track.

The purpose of this research was to compare the oral health behaviors for children and teachers in toothbrushing facilities installed community child center related with teacher-supervised toothbrushing. This research was follow-up study from the Korean Dental Hygienists Association third project '2010 program of making of the diamond tooth'. 266 child support teachers were invited and 201 were included in the study (response rate: 75.6%). Statistical analysis conducted using PASW ver. 18.0 for Windows. The difference on the distribution of independent variables related with teacher-supervised toothbrushing was verified with chi-square test. The results of this research could be summarized as follows: The children in the teacher-supervised toothbrushing community child center, the practice rate of toothbrushing was higher than the children in the non-supervised toothbrushing community child center (p<0.05). Teachers offered children one of snacks and drinks per day independently of teacher-supervised toothbrushing (p>0.05). Most of participated teachers accepted to be responsible for oral health of children (73.4%) and demanded that improve facilities for a toothbrushing in community child center (77.2%). In conclusion, this study suggests that a programme of daily teacher-supervised toothbrushing can be effectively targeted into community child center.

학술 정보유통의 패러다임이 데이터중심 과학으로 연구방법이 변화됨에 따라 사실데이터, 실험데이터 등으로 구성된 과학데이터의 중요성은 커지고 있다. 이에 분야별로 구축된 과학데이터의 개별적 활용 체제보다는 국가 차원에서의 과학데이터센터 구축을 통해 효율적인 과학데이터의 보존, 활용이 필요한 시점에 와 있다. 본 논문에서는 국가 과학데이터센터 구축이 가져오는 경제적 파급효과에 대한 성과분석 모델을 수립하여 차후에 보다 체계적인 성과분석의 효율성 제고와 발전방향의 모색에 활용하고자 한다.

본 논문에서는 센터탭 방식과 배전류 방식의 차이점을 살표보고 각 회로의 변압기 손실을 계산하여 비교한다. 또한 실제 설계한 변압기의 측정한 값을 이용한 손실을 계산 손실과 비교한다. 앞에서 비교한 값들을 이용하여 Matlab/Simulink 프로그램으로 LLC 컨버터의 전류와 전압 파형 등을 알아보고 이에 따른 전체 손실에서 변압기 손실이 차지하는 부분을 비교 분석한다. 따라서 이를 통해 센터탭 방식과 배전류 방식의 손실을 비교한다.
