1970년도 후반까지만 하더라도 염료생산은 선진국형 산업으로만 생각하여 왔으나 인건비 상승, 환경처리비부담, 운성비 등의 부담으로 선직국의 염료생산공장들은 앞다투어 생산기지를 후진국으로 신설 또는 이전을 하게 되었다. 한편 생산량도 증가되어 수요에 비하여 공급과다로 지나친 판매경쟁이 일어나고 채산성도 나빠진 것이 현실이다. 이러한 나라들 중에는 제조기술의 미흡, 원가절감, 품질관리의 미숙 등으로 lot별 농도차이, 용해성불량, 염료중에서의 재응집, 飛散등의 문제로 염색공장에서 애로를 겪는 경우가 자주 발생하고 있다. 특히 염료의 비산 문제는 칭량원의 보건상 나쁜 영향을 미치게 되고 염색현장까지 염료입자가 날아가 피염물에 오염을 일으키기도 한다. 이러한 문제점을 해결하기 위하여서는 다각적으로 관리에 철저를 기하지 않으면 안된다.

본 연구는 (s, S) 재고시스템의 최적 재고정책을 수립하는 문제를 시뮬레이션을 통하여 분석하고자 한다. 이러한 목적으로 재고관리비용에 대한 파라미터 (s, S)의 민감도를 퍼터베이션 분석법으로 구하고 확률 최적화 기법을 적용하여 단위 기간에 평균 재고관리비용을 최적으로 하는 재고정책을 발견하였다. 민감도의 추정에는 IPA법과 SPA법을 표본경로의 주문 사건 변동에 따라 조건적으로 결합하여 사용하였다. 시뮬레이션 결과 s와 S의 최적정책 추정치를 상당히 정확한 값으로 얻었으며 이러한 결과는 보다 일반적인 재고관리 문제의 분석에 도움을 줄 것으로 기대한다.

정부의 정부문서관리법령 개정으로 최근 각 지방자치 단체와 정부 공공기관은 전자문서 시스템 도입 준비에 안창이다. 내년 1월 이후에는 그간 중앙행정기관에서 개발적으로 유통되던 전자문서를 정부전자문서유통센터를 통해 관리함으로써 정부문서처리 전 과정을 전산화, 자동화 하기로 했기 때문이다. 기존의 종이 문서를 전자문서로 변환해 관리하기 위한 노력은 그 동안 각 기업별 또는 기관별로 꾸준히 진행돼 왔다. 특히 인터넷을 통한 각종 정보 서비스의 제공을 위해서는 전자문서 구축은 필수다. 그렇다면 남은 문제는 얼마나 우수한 시스템을 얼마나 비용 효율적으로 구축하는 가의 문제이다. 어도비시스템즈의 PDF솔루션을 통해 전자문서 시스템을 구축하고, 이를 통해 비용절감과 함께 서비스 만족도 향상등 두 가지 토끼를 한번에 해결한 사례를 살펴봤다

The purposes of this paper are to investigate the impact of managers' agency problem on asymmetrical behavior of SG&C and to examines whether or not the corporate governance mechanisms can have any moderating effects on Asymmetrical behavior of SG&C. To test empirically the above mentioned purposes, we gathered firm-year data of manufacturing firms from 2007 to 2012 and the sample firms are listed on the Korean Stock Exchange. The findings of this research are summarized as follows: Firstly, for those firms whose agency problems are high, the stickiness of SG&A increases as sales variation. The results imply that managers are not willing to reduce their perquisite consumption in proportion with sales reduction. Secondly, we investigate how corporate governance mechanisms influence the cost stickiness behaviors of SG&A for those firms whose agency problem are high(above the median value of free cash flow used as a proxy of agency problem). The results are that as the effectiveness of corporate governance mechanisms improve the cost stickiness of SG&A mitigation except for the insider ownership. These results show that agency problem has impact on the asymmetrical behavior of SG&A. And effective governance mechanisms have moderate effects on the reducing stickiness behavior of SG&A caused by agency problem.

The aim of this study is to find the effect of action learning on the problem solving process of nursing students during the clinical practice of nursing management. A total of 99 senior nursing students participated in this study. Data was collected from May 2006 to October 2007 and statistical analysis for paired t-test was performed on the data using SPSS/WIN 14.0. The results of the data show that there was a significant increase in the problem solving process for nursing students after the implementation of action learning(t=-4.718, p=.000). In the problem solving process, there was a significant increase in definition of problem(t=-4.123, p=.004), design of problem solution(t=-2.973, p=.002), execution of problem solution(t=-3.264, p=.000) and investigation of problem solving(t=-3.677, p=.000). The only exception in the problem solving process was detection of problem(t=-1.858, p=.066). Therefore, action learning provides nursing students a new alternative for improving the problem solving process and clinical adaptability after graduating from nursing school.

This study was conducted to compare the creative problem solving styles and conflict management types between engineering college students with high and low team performance records. Most students with high team performance records preferredDeveloper style(76.7%) and Task-oriented style(65.1%), whereas most students with low team performance records preferred Explorer style(72.2%) and Person-oriented style(86.1%). Results of the comparison of conflict management types revealed that most students with high team performance records belonged to a competitive logic type(22.8%) and an accommodative compromise type(17.7%), while most students with low team performance records belonged to an accommodative compromise type(20.3%) and a permissive resignation type(12.7%). It would be useful to provide the engineering students with the specialized program to complement their problem solving styles and conflict management types.

A currently domestic governmental R&D business is early to 100. And this is each managed individually in 15 professional organizations of research and management by characteristics of a business. For this Reason, A redundant investment issue regarding national R&D occurs, and an issue regarding efficiency of R&D investment by insufficiency of systematic R&D research project and result management is continuously raised. Ministry of Education Science and Technology establishing National Science & Technology Information Service(NTIS) in order to solve these issues. NTIS is the national R&D Portal System which can support efficiency of research and development to result utilization in planning of national research and development. In this paper We consider integrated DB constructions and Information Linking of R&D Participants/Projects/Results information in a NTIS system for data quality Improvement. and then We analyze the cause of the data quality problem, and we propose the improvement plan for data quality elevation of NTIS system.

Korea has the glorious documentary cultural heritage including Annals of the Joseon Dynasty, Memory of the World, from old times. But We had been felt into serious situation, it is very difficult to find some records of late years, through rapid changes of society in modern history. Fortunately, in 1999, "law of archives management in public sector" was enacted but It is some difficult to apply to field. Accordingly, We studied archives laws and record management systems, education systems in Japan and China, neighborhood countries and compared them with Korea's. Life cycle of Gathering, Managing, Using records & archives is reflected in China's archives law, "Dangan" and It is useful to referred to Korea. On the other hand, Japan and Korea's archives law focus on administering and capturing records and archives. In case of Management agency of archives, China has a linear managing system from state to regional agency and Japan and Korea have different system in State and Region. We recommend following items ; reform archives law, status of government archives, professional education and arrangement etc.

For effective web-based teaching and learning, it is necessary to estimate. whether activities for it have attained to the learning goal. In HTML and file based item pool systems, it is difficult to manage, to create questions into various forms, and to share with other systems. It is also not easy to provide suitable questions according to the level of learners. On the contrary, XML document can systematically create a structured information. Since XML represents a structure with meaningful information units, it can be effectively used to manage, search, and store documents. Therefore, we designed and implemented a web-based item pool system based on XML, which can support leveled assessment by analyzing the level of learners and providing appropriate questions according to it.
