Workflow management system is a system that manages the workflow model which defines the process of work in reality. We can define the workflow process by sequencing jobs which is performed by the performers. Using the workflow management system, we can also analyze the flow of the process and revise it more efficiently. Many researches are focused on how to make the workflow process model more efficiently and manage it more easily. Recently, many researches use the workflow log files which are the execution history of the workflow process model performed by the workflow management system. Ourresearch group has many interests in making useful knowledge from the workflow event logs. In this paper we use XES log files because there are many data using this format. This papersuggests what are the cardinalities of the temporal workcases and how to get them from the workflow event logs. Cardinalities of the temporal workcases are the occurrence pattern of critical elements in the workflow process. We discover instance cardinalities, activity cardinalities and organizational resource cardinalities from several XES-based workflow event logs and visualize them. The instance cardinality defines the occurrence of the workflow process instances, the activity cardinality defines the occurrence of the activities and the organizational cardinality defines the occurrence of the organizational resources. From them, we expect to get many useful knowledge such as a patterns of the control flow of the process, frequently executed events, frequently working performer and etc. In further, we even expect to predict the original process model by only using the workflow event logs.

To examine the opinions of consumers concerning the ricecake as a traditional food, we conducted the study of the cognition and interests of children and mothers ricecake for its popularization. Our subjects of study were elementary school children as the future consumers and their mothers as the present consumers. The results were as follows: children favored to eat much more western style food and sweet food than did mothers. All of children and mothers liked traditional food and ricecake, but children did not know how to prepare the traditional food and ricecake, indicating thenecessity of the education of ricecake-making. All of them were satisfied with the taste of ricecake 'on sale, but not with packaging designs and price of ricecake. Development of packaging designs was required for popularization of ricecake to spread worldwide.

본 연구의 목적은 사람중심조직의 변화 과정을 간주관적으로 제시하는 것이다. 본 연구는 사람중심실천을 적용하고 있는 장애인복지관의 조직적 변화를 탐색하였다. 이를 위해 사람중심계획을 도입하여 실천하고 있는 전국의 주요 장애인복지관 세 곳에 속한 실무자, 중간관리자 그리고 관장 등 10명의 연구 참여자를 각각 심층 인터뷰하였다. 사람중심실천을 도입하는 과정 중에 겪은 이들의 체험이 포괄하고 있는 조직의 변화 과정에 대한 사실적 측면에 대해, Colaizzi의 분석방법에 따라 현상학적 기술을 시도하였다. 이를 통해 사람중심조직으로 나아가는 동안에 조직 차원에서 경험한 의미 있는 변화를 도출하여, 사람중심실천이 안착해가는 과정과 앞으로 사람중심실천을 위한 변화 등을 열 가지로 범주화시켰다. 본 연구는 사람중심조직으로의 변화가 담고 있는 구체적 의미, 조직 구성원들의 역동 그리고 정책적 변화 방향을 제시하고자 하였다.

Clustered regularly interspaced short palindromic repeats (CRISPR)-mediated genome editing is a ground-breaking biotechnology for agricultural applications such as precision breeding in crop plants. Agrobacterium-mediated CRISPR delivery has been successfully adapted for gene knockout applications for basic research and agricultural technology development. However, selecting proper single-guide RNA (sgRNA) for CRISPR binary constructs to induce double-strand break in certain target genes has presented difficulties mainly due to unpredictable in vivo sgRNA activities. Therefore, more than three independent CRISPR constructs, each harboring different sgRNAs, are often applied to ensure the desired CRISPRinduced knockout alleles. Here, we report a zero-background CRISPR binary vector platform, featuring ccdB conjugation within sgRNA cloning cassette, which is later removed by AarI endonuclease, that allows positive survival selection for bona-fide sgRNA clones and effective exclusion of uncut or self-ligated ‘background’ negative clones. We demonstrate the advantage of using the zero-background CRISPR binary platform in a high-throughput pooled cloning strategy of multiple different sgRNAs which produced Agrobacteria containing multiple sgRNAs without any background. We also tested the integrity of pooled CRISPR sgRNA construct libraries during extended bacterial culture and during the transfer between Escherichia coli to Agrobacterium, and verified that the fidelity of sgRNA species representation was faithfully maintained during library generation.

This study identified the people-centered plan(PCP) as the perspective of 'the practice movement for the integration of people with developmental disabilities.' PCP, by itself, builds a completely different philosophical background from the existing system of support services for people with developmental disabilities. As a result, its introduction and adoption creates conflicts and tensions with existing systems and produces various issues. The purpose of this study is to sort out these issues and to suggest appropriate directions for adopting PCP, based on the results of several studies in US and UK. The issues were largely divided into the complexity of PCP process, ineffectiveness of PCP, organizational redesign and discrepancies in policy. It suggested the importance of the facilitator's role for its proper application and argued that all stakeholders should be involved in the community of practice. 본 연구는 국내에서 관심이 더해지고 있는 사람중심계획을 ‘발달장애인의 진정한 통합을 위한 실천 운동’이라는 관점으로 파악하고 그동안 영‧미권에서 나타난 이슈들을 문헌을 통해 탐색하고자 하였다. 이들 이슈는 크게 사람중심계획 과정의 난해함, 그 적용의 실효성, 기존 조직의 재설계 필요성 그리고 지원 정책과의 어긋남으로 나타났으며, 이를 통해 사람중심계획의 점진적 적용을 위해 각 수준에서 이루어지는 퍼실리테이터 역할의 중요성을 논의하였다. 본 연구는 사람중심계획의 포괄적인 이해를 제고하고 향후 다양한 수준에서 나타날 수 있는 사람중심계획의 통합적인 이해를 돕는 데 의의가 있다.
