In the age of global competition, city brand is a significant element for establishing a city's competitiveness. City branding is the process of building a storytelling about cities' content. Among the various contents that differentiate cities, this study seeks to discuss the role of an event and a city brand in the process of city branding based on the city marketing and event tourism literatures. This research uses grounded theory and a case study to examine Seoul exploring the changes in the Hi Seoul Festival and the Hi Seoul city brand over the last two decades. The qualitative research includes a secondary data analysis based on case studies from domestic and foreign regions and their festivals. The analytical results indicted three limitations: inconsistency, a lack of identity, and political leverage. Based on the limitations, this study discusses the importance of the connection between city identity and event content, suggesting implications for moving forward toward a stable Seoul city branding strategy for the Seoul Metropolitan Government.

This study aims to identify the student assessment competency of the three elementary science teachers and investigate strategic measures to improve them. The study progressed as a qualitative case study method. A self-awareness checklist and in-depth interviews were conducted to collect data. The data analysis was reviewed and agreed upon by two process-focused assessment-leading teachers and two elementary science education experts. Consequently, the level of self-awareness of student assessment competency of the three participants was relatively high. However, the scale average of the feedback area was the lowest on average. The student assessment competency of the participants showed different levels and characteristics. Additionally, some inconsistencies between perception and practice were found. Strategic support and education are needed to enhance elementary science teachers' student assessment competency, and the development of self-diagnosis tools should proceed.

It is not unusual to observe that there Is a great amount of redundant or inconsistent data even within an e-business system such as CRM(Customer Relationship Management) system. This problem becomes aggravate when we construct a system of which information are gathered from different sources. Data quality management is indeed needed to avoid any possible redundant or inconsistent data in such information system. A data quality process, in general, consists of three phases: data cleaning (scrubbing), matching, and integration phase. In this paper, we introduce and categorize data quality operators for each phase. Then, we describe our distance function used in the matching phase, and present a matching algorithm PRIMAL (a PRactical Matching Algorithm). And finally, we present a related work and future research.

최근 경제 사회의 급속한 발전에 따라 개인의 활동분야가 다양해지고 개인비밀보호 인식이 커지면서 응답자들이 통계조사에 잘 협조하지 않는 경우가 늘어나고 있다. 따라서 대부분의 통계를 현장조사에 의존하여 생산하고 있는 통계청에서는 현장조사 결과물의 품질상태에 좀 더 관심을 가져야만 하게 되었다. 이러한 현장조사에 대한 풀질관리의 일환으로 현재 통계청에서는 통계별 조사대상으로부터 품질관리표본(Quality Control Sample)을 추출하고 이를 대상으로 리인터뷰를 실시함으로써 응답오차측정, 조사현장의 실터파악, 응답자 의견수렴 등에 활용하고 있다. 리인터뷰는 조사직원의 고의적인 자료조작 또는 보충교육 필요성 등 현장조사업무를 평가하거나 응답분산(simple response variation), 응답편의(response bias) 등을 산출하고, 이를 분석하는 모델을 이용하여 응답결과의 신뢰도를 분석하는데 목적을 두고 있다. 본 연구에서는 품질관리표본(QC Sample) 설계 및 추출, 리인터뷰 시나리오개발, CATI(Computer Assisted Telephone Interviewing)를 이용한 리인터뷰 기법 등을 통계청 사업체조사 모니터링 사례를 중심으로 설명하고 조사직원 특성별 응답오차 측정 및 비교, 정확성 항목에 대한 차이분석 등 격과에 대하여 논하고자 한다.

지식 베이스는 대량의 인적 물적 자원을 투입하고 철저한 설계에 기반하여 구축하여야 하는 부담이 큰 자원이다. 그렇지만, 지식 베이스 없이 다양한 응용 분야와 서비스를 만족시키는 시스템을 구축할 수 없기 때문에 그 중요성을 인정하지 않을 수 없다. 기존의 지식베이스 구축에 있어서 간과했던 것들의 하나는 응용 분야와 서비스를 명확히 하고, 해당분야에 안는 지식 베이스를 선택해야 한다는 것이다. 어휘의미망을 포함하여 시소러스를 범용 또는 여러 분야에서 구축하고 있으나 이들이 어떤 서비스에 도움이 되는지를 확실히 분석하지 못함으로 인해 응용 시스템에서 제 기능을 다하지 못하고 있으며, 온톨로지 또한 근본적으로 분야와 활용 목적에 의존적이어서 이를 고려하여 설계를 하지만 시소러스나 용어 사전과 같은 기본적인 지식 베이스와의 연계를 통한 효율성 재고라는 측면에서 약점을 보여왔다. 본 연구에서는 사용자 질의와 실 데이터간의 어휘 불일치 해소를 위해 시소러스를 설계 구축하고 온톨로지의 사례화 결과인 인스턴스와 연동시킴으로써 연구자 간 협업 지원 서비스를 제공할 수 있는 기반 자원으로서의 지식 베이스 구축에 초점을 둔다.

In this study, elementary school students' responses toward a discrepant event about a float-or-sink problem were investigated through semi-structured interviews. Initial participants were 61 fifth-grade students from two elementary schools. After excluding the students who did not possess the target misconception from the results of a preconception test and who were not willing to participate in an interview, 31 students (14 males and 17 females) were finally interviewed by two teacher-interviewers. During the interviews, students were first provided with a hands-on experiment which was the same as the situation in the preconception test, and then they were asked about believability of the discrepant event, inconsistency between the discrepant event and their existing conceptions, and belief change after experiencing the discrepant event. Interviews were audio- and video-taped, and then were transcribed by two interviewers. After analyzing the interview transcriptions, we found four types of students' responses; rejection, uncertainty, peripheral belief change, and belief change. We also found that belief change response type should be classified into three distinctive subtypes; belief decrease, ad-hoc belief change, and analytical-abductive belief change.

Even though FOPDT(First-Order Plus Dead-Time) process is most widely applied in the industrial control field, it is difficult to figure out a in precise process model because of the long dead-time problem. Also, control performance may be deteriorated due to the mismatch problem of plant and model. Thus, the accuracy of process identification is the most important problem in FOPDT process control. In this paper, the proposed method using real-coded genetic algorithm outperforms the existing estimation methods that use step-test responses. The proposed strategy obtained useful result through a number of simulation examples.

최근 서비스 지향 아키텍처 (Service Oriented Architecture SOA) 기반의 애플리케이션 개발에 맞게 비즈니스 프로세스의 유연성을 확보하고 재사용을 증진시키기 위하여 비즈니스 프로세스 패밀리 모델(Business Process Family Model: BPFM)이 제시되었다. BPFM은 소프트웨어 프로덕트 라인 방법의 가변성 분석 기법을 사용하여 비즈니스 프로세스 군 (family)에서 나타날 수 있는 가변성을 분석하여 이를 명시적으로 표현하고 있는 모델이다. BPFM으로부터 여러 개의 BPM (Business Process Model)을 개발하기 위해서는 가변성 결정 및 가지치기 (Decision and Pruning) 과정을 거쳐야 한다. 이 때 가변성 사이에는 서로 협력적 또는 배타적인 관계를 가질 수 있고 이는 가변성 결정과 가지치기에 영향을 미치게 되는데, 현재 제시된 BPFM에는 이러한 바인딩 정보에 대해서 아직 고려하지 않고 있다. 본 논문에서는 비즈니스 프로세스 군에서 식별될 수 있는 가변성들 사이의 의존관계의 유형을 분석하고 이 정보를 모델의 형태로 나타낼 수 있는 방법을 제시한다. 먼저 BPFM에 포함된 가변성 정보를 독립된 의존관계 분석모델로 추출해 내고 각 가변성 결정유형에 따라 표현방법을 제시한다. 추출된 모델에서 의존관계를 표현하고 가변성 결정이 영향을 미치는 범위의 가변성들을 클러스터할 수 있는 방법을 제공한다. 본 방법을 이용함으로써 가변성 결정회수를 현저히 줄일 수 있음을 사례연구를 통해 보여준다. 또한 잘못된 가변성 결정으로 인한 BPM의 기능 불일치를 해소할 수 있음을 보여준다.

With the evolution of communication networks, there is a growing demand for stable high-speed data connections to support services relying on large-capacity data. The increasing volume of packet data aggregated from user devices underscores the significance of quality diagnostics for the backhaul network, an intermediate link transmitting data to the core network. This paper conducts empirical research on techniques to diagnose issues within the backhaul network through practical case studies, through diagnosing various factors such as circuit bandwidth, speed disparities within switches, network segment-specific buffer sizes, routing policies, among other factors that could potentially cause RTT (Round Trip Time) delays and performance degradation.
