Purpose This study is to phenomenologically discover key antecedents and outcomes of behavioral process of SNS users who have multiple SNS sub-accounts. Unlike previous studies that focused on user behavior in the context of a specific SNS platform, this study attempts to describe how and why individual manages their multiple sub-accounts across a variety of SNS platforms. Design/methodology/approach By applying the grounded theory methodology (GTM) to elucidate the unique behavior in SNS platforms, this study has conducted in-depth interview with 14 respondents who handle multiple accounts across the SNS platforms. As a results of analyzing the interview manuscripts, this study has extracted 47 concepts, 10 sub-categories and 6 main categories by conducting open coding, axis coding, and selective coding. Findings By analyzing interview data, this study has derived main categories such as account management, impression management, self-categorization, authority to determine the relationship, digital shadow work, and portfolio SNS accounts from qualitative interview data. This study has also conducted a process analysis that represents how main categories could be inter-related. Based on findings, this study provides a new phenomenological perspective to understand the behavioral process of SNS users' sub-account usage experience.

This study aimed to quantitatively analyze the risk using data from 329 safety accidents that occurred in aquaculture fisheries management vessels over the recent five years (2018-2022). For quantitative risk analysis, the Bayesian network proposed by the International Maritime Organization (IMO) was used to analyze the risk level according to the fishing process and cause of safety accidents. Among the work processes, the fishing process was analyzed to have the highest risk, being 12.5 times that of the navigation, 2.7 times that of the maintenance, and 8.8 times that of the loading and unloading. Among the causes of accidents, the hull and working environment showed the highest risk, being 1.7 times that of fishing gear and equipment, 4.7 times that of machinery and equipment, and 9.4 times that of external environment. By quantitatively analyzing the safety accident risks for 64 combinations of these four work processes and four accident causes, this study provided fundamental data to reduce safety accidents occurring in aquaculture fisheries management vessels.

In this study, the impact of organizational culture on the quality of social work services in hospitals were empirically analysed. A mailed questionnaire survey was conducted between February 19 and April 10, 2001. A sample of total 70 hospitals, including general hospitals with one social worker at least and single-department hospital with two social workers or more, were identified nationwide through the registry of Korean Association of Medical Social Workers and Korean Association of Hospitals. According to coping strategy and reacting pattern with the environmental changes, four types of organizational culture in each hospital, classified as group culture, developmental culture, hierarchial culture, and rational culture, were adopted for the independent variables. Three dimensional aspects of quality of social work service - structure, process, and outcome were selected as dependent variables in this study. Also the quality of social work service was distributed into provider-perceiving quality and consumer-perceiving quality The major findings were as following in summary; First, most social workers reported that the characteristic of culture in their hospitals are group culture the first, hierarchial culture the second, developmental culture the third, and rational culture finally in order of comparing the level of quality perceived between social worker's recognition. Second, service provider and consumer, The provider-perceiving quality showed less score than that of consumer, especially the lowest was the score of quality of outcome perceived by provider. Third, according to the types of organizational culture, there were significantly different levels of quality in total social work services, structure dimension and process dimension. The quality of outcome dimension did not show significant differences among the type of organizational culture. Finally, the most influential variables to the quality of social work service ice proved departmental form of social work unit, leader of social work unit, and developmental culture of hospital To assure quality services, accordingly, social work unit in hospital is required to be organized as a single unit, that means to be an independent department of which qualified social worker is supposed to control the unit. It is strongly recommended to develop leadership for the leaders of social work unit.

초고층 건축공사에서 리프트카를 이용한 자재 양중 관리는 핵심적인 관리분야 중 하나이다. 기존 연구들은 양중계획의 기본 단위인 양중 사이클타임이나 리프트카의 운행효율은 기존 사례를 참고하여 적용하거나 관리목표로 설정하고 개략적으로 산정하는 한계가 있었다. 따라서 본 연구에서는 양중 사이클타임을 단축하고 가동율을 향상시키기 위하여 자재 양중작업 프로세스를 최적화하는 방법론 제안을 목표로 하였다. CYCLONE 모델을 변형하여 작업시간과 작업위치를 반영할 수 있도록 개선하고, 세부 작업을 조정하여 프로세스를 최적화 하는 방법론을 제안하였다. 이 방법론에 따라 양중작업 프로세스를 개선하고 민감도 분석과 현장 적용성 평가를 실시하였으며 초고층 현장에 적용하였다. 기존 작업 프로세스와 개선된 작업 프로세스를 양중 높이별로 시뮬레이션하고 이를 현장 적용 결과 데이터와 비교하여 양중작업 시간 단축과 가동율 향상 정도를 비교 분석하여 최적화 방법론의 효용성을 검증하였다.

The yield and quality of a micromanufacturing process are important management factors. In real-world situations, it is difficult to achieve a high yield from a manufacturing process because the products are produced through multiple nanoscale manufacturing processes. Therefore, it is necessary to identify the processes and equipment that lead to low yields. This paper proposes an analytical method to identify the processes and equipment that cause a defect in the plastic ball grid array (PBGA) during the manufacturing process using logistic regression and stepwise variable selection. The proposed method was tested with the lot trace records of a real work site. The records included the sequence of equipment that the lot had passed through and the number of faults of each type in the lot. We demonstrated that the test results reflect the real situation in a PBGA manufacturing process, and the major equipment parameters were then controlled to confirm the improvement in yield; the yield improved by approximately 20%.

4차 산업 혁명의 실현이 구체화 되면서 기업 업무환경에 대한 패러다임이 전통적 노동환경에서 디지털 노동환경으로 변화되어가고 있다. 특히 RPA(Robotic Process Automation), 챗봇과 같은 기술들은 단순 반복적인 작업을 자동화하여 인간의 노동량을 감소시키고 인간이 더욱 가치 있는 작업 또는 노동에 집중할 수 있도록 지원한다. 본 논문에서는 퍼블릭 클라우드 컴퓨팅 기반의 경비지출관리 솔루션을 활용하고 있는 기관이나 기업들이 이러한 로봇 프로세스 자동화 기술과 챗봇 기술을 접목하여 경비지출 보고서 관리 업무를 간소화하는 클라우드 모듈을 개발한다. 개발된 모듈은 전문가 평가를 진행하여 80.3%의 만족도를 보였고 용이성 측면에서 가장 높은 94%의 만족도를 확인할 수 있었다. 연구 결과를 바탕으로 향후 연구에서는 경비지출관리 업무와 관련된 업무 시스템을 추가로 연계하여 기업 내·외부에서 발행하는 업무를 단일 RPA 환경으로 확장하고자 한다.

지식 혹은 기술을 중심으로 연구개발 등 업무 프로세스가 이루어지는 연구소에서 지식관리의 중요성이 더욱 강조되고 있다. 연구개발은 조직의 성장 엔진 역할을 담당하고 있으며, 지식 및 경험을 유기적으로 통합 공유하여 새로운 지식을 창출하는 과정인 업무 자체가 지식관리 프로세스라 할 수 있기 때문이다. 본 연구에서는 연구 프로세스 기반 지식관리 프로세스를 도출하고, 실제로 이러한 체계의 지식관리를 추진하고 있는 포스코경영연구소의 사례 연구를 통해 지식관리의 실천적 모델을 제시하고자 한다.

It compared subcontractor with contractor that are wages, the labor hour and labor condition of the work environment back are inferior relative. The subcontractor which basically the contract workers evade the dangerous process or the difficult work, the dirty work back what is called 3D the case which does to keep a business is many. so With life it will be threatened consequent health directly. The possibility where the subcontractor will be exposed to danger work came to be high. Consequently it prevents the subcontract which danger work is insensitive from this research and immediacy of the subcontract workers who is weak hygiene circumstance complement the plan it will be able to secure the immediacy safety&health subcontract workers, substantially to prepare in the hazard subcontract proprietor. Thus, this paper aims at presenting countermeasures to substantially secure safety and health of subcontractors by preventing ill-advised subcontracting of harmful and hazardous operations and imposing partial occupational safety and health responsibility to employers to enhance safety and health environment of subcontractors.
