In the standard assumption of statistical process monitoring (SPM) under consideration, the in-control region of the control parameter of quality characteristic consists of a single point. However, if small deviations from the ideal situation may not be of practical importance, the parametric space can consist of three regions: In-control, indifference, and out-of-control. In this paper, we propose two exponentially weighted moving average (EWMA) charting procedures applicable to the situation with three parameter regions, and compare the efficiency of the proposed procedures with the Shewhart chart and the cumulative sum (CUSUM) chart.

This paper reports a comparative review of the service quality attributes of Electronic Customs Clearance (UNI-PASS) by applying the Kano model, Timko's BW coefficients, and IGA model, as reported by Tontini et al. in terms of a service quality evaluation of electronic customs clearance as the comprehensive national customs administration information system. In addition, this study examined which quality attributes should be focused on to improve the service quality and enhance customer satisfaction using the electronic customs clearance service. The Kano, Timko, and IGA models were classified into the four common quality attributes: attractive quality, one-dimensional quality, must-be quality, and indifferent quality. Because the integrated approach was used, one-dimensional quality was included in the area for critical improvement, while the must-be quality was included in the area for intensive maintenance. In addition, the indifferent quality was included in the area of carefree, while the attractive quality was included in the area of competitive advantage.

Due to the inferior condition of local library reference service, an air of indifference about users, and the increase in Internet resources, cooperative reference service in domestic libraries tend to be stagnant. The increase in Internet resources was reconsidered, aside from traditional library reference service, based on question and answer service. It shed new light on the importance of indirect service, which is focused on reliable knowledge base construction. This study analyzed cooperative reference service, which is managed by the Japanese Diet library that pursued indirect service contrary to ours. Based on that, it suggested a new takeoff possibility for Korean cooperative reference service.

모든 과학기술지식은 객관성을 지닌 관찰과 실험과 측정에 의해서 이루어진다. 이렇게함으로써 과학기술지식은 재현성과 영구성을 가져오게 되며, 올바른 전승과 누적적 발전을 가져오는데 이 과학기술지식의 질서체계를 유지하는데 근본적인 역할을 하는 것이 표준이다. 시간, 길이, 온도, 무게 등의 기본 측정단위와 광속, 중력 등의 물리화학적 상수, 법정계량단위, 각종 공업 규격, 안정 규정 등 수 없이 많은 표준은 효과적인 공동 인식과 객관적 판단의 기준으로 활용되고 있다. 현대의 과학기술이 다양하게 발전하고 이에 따라 우리의 생활도 더욱 복잡한 구조를 이루면서 표준에 대한 필요성도 더욱 높아가고 있다. 표준에 대한 깊은 생각없이도 우리는 자동차에 주유할때 표준단위를 통해 원하는 분량을 말하며, 카메라의 필름 종류를 선택할 때도 국제표준기구(ISO: International Standards Organization)의 규격을 사용하는데 익숙해져 있다. 이렇게 표준은 우리 일상생활과 밀접한 관계에 있으나 소비자 입장에서는 그 가치를 절실히 느끼지 못한 것이 사실이며 표준이 없음으로 해서 일어나는 불편과 혼란에 대해서는 무관심한 것이 사실이다. 일상생활에서 일어나는 표준의 역할을 우리가 잘 이해한다면 표준이 왜 필요한가를 쉽게 인식하게 될 것이다. 최근 정보산업이 새로운 물결로 사회전반에 영향을 미치고 있으며 이에 따라 정보의 수집, 가공, 저장 및 배포의 처리 과정에서도 제반 표준화의 필요성이 크게 대두되었다. 그 결과로 최근 10여년간에 수백종의 기술기준, 지침서 및 기본/기능 표준규격이 제정되어 왔다. 이와 같이 어떤 특별한 영역에서의 표준에 대한 요구가 있을 때 관련 규격이 제정되게 된다. 표준의 제정을 위한 다음 단계는 그 주제에 관한 표준(또는 규격)개발에 관심을 가진 사람들이 모이는 일일 것이다. 통계분야에서도 몇가지 표준화 활동이 ISO 를 중심으로 진행되고 있다. 예를 들면 실험과 검증 결과의 표현과 해석, 표본추출 방법 등에 관한 것으로 이들은 통계의 응용분야에서 꼭 필요한 표준이다. 구체적인 예로서 우리나라 국민의 표준체위값을 설정하기 위하여 측정조사할 때 측정방법 뿐 아니라 표본추출 방법과 통계자료 처리과정의 표준화가 이루어 지지 않는다면 각 기관에서 조사 발표하는 체위관계 자료가 상이하여 국가기관의 통계자료에 대한 신뢰성이 저하되고 통계값을 이용하여 의류, 신발 등의 제품을 제조하는 산업계에 혼란을 야기시킬 수 있다. 본 고에서는 ISO의 활동을 정보처리 분야에 초점을 맞춰 간략하게 설명하고 통계분야의 국제 활동을 비전문가인 필자들이 아는대로 소개하는 한편 국내활동의 필요성을 강조하여 관련 기관, 학계 및 산업계 관련전문가들의 ISO 국내활동 참여를 제의하고자 한다.

The aim of this study was to identify the type of occupational balance of college students and analyze the differences between positive or negative emotions according to degree of flow. The Experience Sampling Methods (ESM) were conducted for 12 college students using smart phones. As a result, in activities of daily living group, apathy showed the highest percentage (34%) and in over work group, flow showed the highest percentage (41%). In occupational balance group, frequency of labor and leisure activities was high but boredom was experience a lot in leisure activities. When the students experienced flow in main activities, mean score of positive emotions showed the highest value. Through this study, we identified the differences of flow experience in occupational performance based on type of occupational balance and confirmed improvement of positive emotions in activities experienced flow.

The purpose of this study is to investigate the depth of earth science teachers' concern over the 7th Science Curriculum and levels of their use of it in reality, using the tools "Concern" and "Levels of use" which are two important tools use in CBAM. The results of the study are as follows. How much concern do the earth science teachers have over the 7th Science Curriculum? There are seven stages (from 0 stage to 6 stage) of teachers' concern over the curriculum. o stage represents teachers' indifference to the curriculum and 98% teachers are placed in this stage. According to the study on teachers' teaching experience, teachers having from 10 to 14 years of teaching experience are the most indifferent to the 7th Science Curriculum, compared to other teachers. Which levels of use of the 7th science curriculum do earth science teachers choose in reality? There are five levels of use (from 1 to 5) of the 7th curriculum. 43.97% of teachers are placed in the 3rd level called "Mechanical level", which represents a teacher-concerned learning method with consideration of learners' response. According to the study on teachers' frequency of level of use in the fields of "Instruction objects, Instruction contents, Instruction methods, Instruction materials and Evaluation.", teachers chose high levels of use in the fields of "Instruction objects and Instruction contents" and low levels of use in the other three fields. What factors are barriers for earth science teachers to perform the 7th Science Curriculum in reality? 80.9% of teachers have trouble performing the 7th Science Curriculum in reality because of too much routine work, official papers, and lack of instructional materials, laboratories, training systems and workshops. The two biggest barriers among the above are routine work and of official papers. According to the study on teachers' teaching experience, teachers having from 0 to years of teaching experience have the most trouble in performing the curriculum in reality, compared to other teachers.

Objectives : Behavioral and psychological symptoms of dementia(BPSD) represent significant clinical problems, resulting in functional decline, caregiver distress, institutionalization and increased mortality. A recent study showed gender differences have important role in the development of BPSD, but relationship between BPSD and gender has never been studied in Korea. This study was designed to examine whether patients with Alzheimer's disease show gender differences in behavioral and psychological symptoms of dementia(BPSD). Methods : Ninety-eight subjects with Alzheimer's disease were included in this study. We carried out history taking and cognitive assessment for the diagnosis of Alzheimer's disease based on DSM-IV. Cognitive impairment and BPSD were measured using the Mini Mental State Examination(MMSE), Global Deterioration Scale (GDS), Clinical Dementia Rating(CDR) and the Korean Neuropsychiatric Inventory(K-NPI). Independent samples t-test was used to examine the differences across gender in BPSD. Correlation analysis between MMSE, CDR, GDS and NPI was performed using Pearson's correlation coefficient. Results : There were no significant gender differences between the gender in BPSD. We found statistically significant negative correlations between MMSE with NPI total score, and with scores of several sub-domains such as hallucination. Conclusions : This study showed that gender differences in BPSD are not significant. Further research is necessary to identify whether BPSD affect gender differences or individual differences.

In preparation for the adoption of software(SW) education in Korea by 2018, this study examined Korean teachers' perceptions and attitudes toward SW education and their relationship with teacher characteristics. By using the Stages of Concern Questionnaire, we conducted a survey of 92 teachers who participated in an introductory level of SW teacher training. The findings indicated that 1) the teachers' profile follows the typical nonuser pattern focusing on more self-concern, with the strongest intensity at Stage 0-Unconcerned and 1-Informational concern and the lowest at Stage 4-Consequence. However, teachers' stages of concern differed from the teachers' characteristics. Male teachers exhibited more concerns at Stage 4-Consequences, Stage 5-Collaboration, and Stage 6-Refocusing than female teachers. In addition, the teachers with higher SW proficiency, SW training experiences, and longer SW teaching experience showed higher intensity at Stage 4, 5, and 6 than their counterparts. The study suggests that the implementation of SW education would be effective and facilitated when teachers receive on-going and appropriate interventions and educational supports based on their individual concerns.
