Recommender system is a core component of e-commerce. Correspondingly, metrics to evaluate the system performance have been developed and applied. However, even though we have lots of applications that have tried to adopt recommender systems, the dearth of successfully installed recommender systems for more than a decade leads us to a skeptical thinking that current metrics do not sufficiently indicate the recommender system success in business viability point of view. Hence, the purpose of this paper is to reconfigure measures for recommender system success. Adopting DeLone and McLean's amended model of information system success as the underlying framework, content analysis with intellectual properties on recommender systems was conducted to modify the currently used metrics. Then a model of recommender system success is proposed based on the newly identified metrics are compared with traditional metrics.

Purpose: The purpose of this study was to find useful solutions by analyzing causes and results about defects on mechanical drawing notes and provide an automated tool with solutions to mechanical engineers. Methods: The collected data for defects on mechanical drawing notes were from ongoing development and mass production projects. Various measurement methods were used based on the Lean 6 Sigma analysis such as Process analysis, C&E diagram and some statistical analysis. Results: The results of this study are as follows; The results of the Lean 6 Sigma analysis, the validity of the selected indicators for improving drawing notes quality was verified through the verification of cause variables. The strategy established to improve the mechanical drawing notes was reflected as an automated program, and the defects were within a manageable range and achieved target Sigma level. Conclusion: Through the application of the "Mechanical drawing notes automation tool", it is expected to resolve the "Voice of Customer, VOC" and "Voice of Business, VOB".

The purpose of this study was to analyze Hanwoo usage in restaurants and to develop menus of lean cut Hanwoo. Restaurant served customers Hanwoo menus, with the exception of broiled or roasted meat, mainly to provide various menus to customers (4.14), due to customer needs (3.87) and utilizing stocks (3.59). On the other hand, the reason for not providing Hanwoo menus, with the exception of broiled or roasted meat was manpower shortage (3.63), lack of popularity (3.58), low profit (3.29), preservation of Hanwoos' original flavors (3.28) and complex cooking methods (3.22). Concomitantly, the restaurant owners' intentions to apply new menus with lean cut Hanwoo was 73.4%, showing an interest in developing new menus and recipes using lean cut Hanwoo suitable to the changing owner awareness of customer health and trends. This study has established a standard for developing cooking methods and developed menus according to classified recipes for lean cut Hanwoo, based on the survey of restaurants' current status of using Hanwoo and the owners' opinions. 20 menus using lean cut Hanwoo (rump or shank) were developed by $1^{st}$ and $2^{nd}$ cooking experiments, and in-depth interview of experts-groups. Of these, 12 menus suitable for the restaurant were finally selected based on the results of consumer's evaluation using JARS. Structured recipe flow diagram and recipe instructions were developed for future semi-processed or processing foods. Diverse recipe methods using lean cut Hanwoo were obtained from the study, however aggressive public relations work is required for promoting the developed menus.

소프트웨어 산업은 아직도 뿌리깊은 문제에 시달리고 있다. 어떻게 보면, 제조업과 같은 보다 성숙한 산업의 모범사례로부터 뭔가를 배워야 할 지 모른다. 제조업에서의 '린' 원칙을 소프트웨어 개발에 적용하는 것도 한 방안일 수 있다. 소프트웨어공학 문헌에서 이런 '린' 원칙은 시도해 볼만 한 것으로 언급되었다. 그러나 이들 원칙을 실제 어떻게 적용할 수 있을 가에 대한 구체적 방안을 제시한 연구는 별로 없었다 본 연구는 '린' 원칙을 소프트웨어 개발에 적용하는 방안을 제시하고자 한다. 이 방안의 핵심은 낭비제거라는 린의 관점을 구체화하기 위하여 프로젝트에서의 리드 타임과 결함을 누적 흐름도(Cumulative Flow Diagram)을 통해 관리하는 방법이다. 또한 이 방안을 실제 프로젝트 사례에 적용함으로써 타당성을 검증하고 적용 방법에 대한 이해를 돕고자 하였다.

우리 건설산업은 2000년 이후 공공부문의 발주액이 꾸준히 증가하고 있다. 하지만 현재 국내 공공사업에서의 비용, 일정 그리고 품질관리는 일반적으로 결과 중심적인 관리행태에 의존하고 있음과 공사 중 투명한 관리가 이루어지지 못하고 있음으로 인하여, 비용과 일정의 증가, 부실시공, 문제점의 조기발견과 대책수립의 어려움, 그리고 시공자, 감독자, 설계자 사이의 책임소재 불명확 등의 문제를 야기하고 있는 것으로 인식되고 있다. 따라서 본 연구에서는 공공부문 관급공사의 발주자조직을 대상으로 현 관급공사의 발주자의 관리실태를 파악 및 분석하여 그 문제점 및 관리의 한계를 도출하고자 한다. 또한 도출된 문제점과 한계를 보완 또는 개선할 수 있는 모델을 발주자 조직에 제시하여 보다 나은 발주자의 효율적이고 실질적인 프로젝트관리업무 향상에 기여하고자 한다.
