Differing from civil engineering and construction, landscape architecture projects are far from efforts in operation and project management. Under the circumstances, it is worthwhile to adopt scope definition from project management for construction and civil engineering in some respects. First, scope definition is able to be conducted through a simple procedure without additional investment in capital and time. Second, the output produced by scope definition is very substantial. The research scrutinized scope definition procedures accompanied by landscape architecture project execution and derived various methods in order to help scope definition for efficient landscape architecture projects. Based on the literature review, a design case study, and an exert interview, the project success elements were developed consisting of 3 sections, 8 categories and 50 elements, grounded on the theoretical base of PDRI. The elements are expected to pave a way to an adequate level of scope definition among participants of landscape architecture projects and contribute in efficient project execution.

This study aims to do in-depth exploration of the meaning of learning village activists' work, focusing on job crafting. A qualitative case study was conducted through participant observation and in-depth interview from March 23, 2020 to March 05, 2021. As a result of the analysis, a task crafting showed 'task performance using one's own strengths and resources', 'executing additional tasks other than the specified tasks', and 'changes in work methods for efficient task performance'. In a cognitive crafting, 'recognition of the importance of work and sense of vocation', 'recognition of happiness and pleasure in work', and 'recognition of roles to expand work expertise' appeared. In a relation crafting, 'building a community of practical learning with colleagues', 'a mediator of the growth and change of village residents', and 'coexistence of conflict and cooperation with business associates' were shown. In conclusion, learning village activists were actively changing their work through the job crafting and this can be used as basic data to improve the satisfaction with their work. A follow-up study was proposed for activists in learning villages in other regions.

This paper suggests a technique for evaluating cognitive process when a working group performs its group tasks. First, it review a theory of distributed cognition which provides a theoretical background for investigating group's cognitive process. Then, it presents a procedure for DGOMS(Distributed GOMS) evaluation which is an extension from GOMS. GOMS is an analytica evalutation technique that has been used at the individual level. DGOMS analyzes task completion time and compares workload among group members on the basis of each member's task execution time, communication time, and cognitive workload. DGOMS can be applied to a situation where a group of people are working together for a common goal using a technical subsystem such as information systems.

In an effort to identify predictors of job performance, research studies in social work administration has been so far on the individual practitioners' levels of knowledge and skills, which could be used in a workplace. As the theoretical concept of organizational environment was fully introduced into social work administration research, however, studies on practitioners' job performance began to have interest in the team or the organizational level variables as well as individual level variables. Along the course of this tendency, this study attempted to test the effect of individual, team, and organizational level variables on the job performance of human service workers. The individual level variables consisted of knowledge, skills, job satisfaction, personality, and counter-productive work behaviors of workers. The team or the organizational level variables included situational constraint, organizational justice, job characteristics, government-dependency, and inter-organizational cooperation. Multi-level complex survey data collected by cluster sampling method from 314 practitioners in 23 organizations were analyzed using Hierarchial Linear Model. Results showed that both task and contextual performance were affected by individual, team, and organizational level variables in various ways.

The purpose of this study is to verify the relationship between psychological capital and job performance of social workers at welfare centers for the disabled. For that purpose, a self-reported questionnaire survey was conducted on 900 social workers at welfare center for the disabled nationwide, and a total of 864 copies of data were used for the final analysis. As a result of the main analysis, first, there was a positive(+) correlation between self-efficacy, hope, optimism, resilience which are the sub-elements of psychological capital, and contextuality and task performance, which are the sub-elements of job performance. Second, among the sub-elements of psychological capital, self-efficacy and hope showed statistically significant positive(+) effects on task performance. Third, it was found that optimism as well as self-efficacy and hope had a statistically significant positive(+) effect on contextual performance. Based on those findings, this study suggested practical and policy alternatives to improve the job performance of social workers at welfare centers for the disabled.

탐색회의는 조직이나 지역사회의 사람들로 하여금 그들의 가장 바람직한 미래를 규정하고 참여에의 책임감을 강조하는 과업수행을 위한 전략을 만들어낼 수 있도록 하는 참여적 계획 방법이다. 참여자들은 가능한 한 다양한 배경을 지닌 사람들이며, 그리하여 그들이 지니고 있는 지역사회에 대한 자신들의 지식과 과정을 변화시킬 수 있는 기술을 가지고 지역사회 개발에 기여할 수 있다. 탐색회의는 이루어져야만 하는 특별한 활동들을 규정하고 필요한 변화를 만들어낼 책임을 지니는 사람들에게 힘을 부여함으로써 표준적인 전략 계획보다 훨씬 더욱 유용한 결과를 산출한다. 계획과정에의 전체 지역사회의 참여는 바람직한 결과를 지역사회 전체가 소유할 개연성을 증가시키는 데, 이는 과업을 수행하는데 필수불가결하고 지역사회가 희망하는 목표를 성취하는데 중심적인 조건이다. 효과적인 지역사회 개발 계획을 위한 탐색회의의 성공적인 수행을 위해서는, 중앙정부가 지방정부의 탐색회의와 관련된 교육프로그램을 제공해야 하는데, 이는 탐색회의가 참여자들을 조직하고 관리하는 따위와 같은 얼마간의 기술을 필요로 하기 때문이다.

The purpose of this study is to investigate the effects of task conflict on job attitudes (organizational commitment & job satisfaction), focusing on the mediating effects of supervisory communication & co-worker communication. Recently, the importance of communication as a research topic has been increasing. According to prior research, communication satisfaction has a positive effect on job performance. However, studies which take into account the different types of communication are lacking. Therefore, this study considered two types of communication (supervisory communication and coworker communication). A research model and hypotheses were developed in order to examine the theoretical research issues and questions. The sample consisted of 280 survey data drawn from employees in firms located in Korea. The data was analyzed by the statistical packages, SPSS 21.0 & AMOS 21.0 for Windows. The findings of the analysis are as follows. Firstly, it was found that task conflict had a negative (-) effect on organizational commitment & job satisfaction. Therefore, H1a & H1b are supported. Secondly, it was found that task conflict had a negative (-) effect on supervisory communication. Therefore, H2a is supported. However, it did not have a significant effect on co-worker communication. Hence, H2b is not supported. Thirdly, as regards the mediating effect of supervisory communication, it was found that supervisory communication mediated the effect of task conflict on job attitudes (organizational commitment & job satisfaction). Therefore, H3a & H3b are supported. Finally, the mediating effect of co-worker communication was not significant. Therefore, none of the sub-hypotheses of H4 are supported. Based on these findings, this study suggested directions for future research.
