  • Purpose: The purpose of this study was to identify the types and causes of non-value-added (NVA) activities in nursing practice, and to determine the frequency of each NVA type and causes of NVA in clinical area. Methods: This study was conducted using Delphi technique. First, in order to identify NVA and their causes, 24 nurses with 7 years or more of clinical experience were recruited from medical/surgical units in six general hospitals in Korea. Then the NVA types and causes were tested using a larger sample of 130 nurses with more than 3 years of clinical experience at two general hospitals in Korea. Results: NVA was categorized into 6 different types, which are repeating, duplicating, waiting, reverse-proxy working, reworking, and searching. The most prevalent NVAs were repeating and duplicating works. Reworking and searching were less frequent types than others. The causes of NVA were classified into personnel-related, supporting departments, records, regulations, information, materials or instruments, and others. Among them, personnel-related and supporting departments were reported with the highest scores. Conclusion: NVA leads to waste cost and time. These results demonstrated the situations and causes of NVA occurred in nursing practice. Further studies on the typology and moderation of NVA activities are warranted to improve the efficiency and quality of nursing care in day-to-day practice.

  • As buildings become higher, larger, and more complex, safety issues for construction workers working at such environments become more important. We analyzed 140 critical accident cases reported to the KOSHA(Korea Occupational Safety & Health Agency) for construction cranes and lifts by types of cranes and by patterns of accidents and causes. By finding out the accident's types and causes, we expect to develop an efficient measure for preventing similar accidents in the near future. The cases will be studied further and reexamined using the FMEA(Failure Mode and Effect Analysis) as a quantitative analysis method.

  • The international nuclear industry has undergone a lot of changes since the Fukushima, Chernobyl and TMI nuclear power plant accidents. However, there are still large and small component deficiencies at nuclear power plants in the world. There are many causes of electrical equipment defects. There are also factors that cause component failures due to human errors. This paper analyzed the root causes of failure and types of human error in 300 cases of electrical component failures. We analyzed the operating experience of electrical components by methods of root causes in K-HPES (Korean-version of Human Performance Enhancement System) and by methods of human error types in HuRAM+ (Human error-Related event root cause Analysis Method Plus). As a result of analysis, the most electrical component failures appeared as circuit breakers and emergency generators. The major causes of failure showed deterioration and contact failure of electrical components by human error of operations management. The causes of direct failure were due to aged components. Types of human error affecting the causes of electrical equipment failure are as follows. The human error type group I showed that errors of commission (EOC) were 97%, the human error type group II showed that slip/lapse errors were 74%, and the human error type group III showed that latent errors were 95%. This paper is meaningful in that we have approached the causes of electrical equipment failures from a comprehensive human error perspective and found a countermeasure against the root cause. This study will help human performance enhancement in nuclear power plants. However, this paper has done a lot of research on improving human performance in the maintenance field rather than in the design and construction stages. In the future, continuous research on types of human error and prevention measures in the design and construction sector will be required.

  • This study tried to examine the conflict relationships and solutions among the members of a hospital structure, a structure composed of various experts and professionals. As the situations causing conflicts are very different depending on the sizes or structural types of hospitals, the samples were collected from total 235 people of 17 medical specialists, 46 residents, 74 nurses and 74 medical technicians, 40 administrators in a university hospital for clearing conflict relationships. The result showed that a hospital had separately different the conflict causes according to all types of occupations. That is, there were various conflict relationships such as the conflict with the medical specialists, with residents, with nurses, and with administrators, and resulted in respectively different causes from those conflict relationships. In addition to, looking into the top of conflict causes, the respondents in all occupations attributed the conflict with medical specialists to "authoritative attitude" of medical specialists, and attributed the rest types of conflict relationships to "lack knowledge of the work". And then, in terms of the top of conflict solutions according to the occupational types in the hospital structure, medical specialists and administrators chose competition & cooperation, and the way for residents, nurses and medical technicians was situation-avoidance. The competition & cooperation type, negotiation type and situation-avoidance type, among solution types, were little difference regardless of occupations, but in case of work-avoidance type, there were significant differences according to residents, nurses, medical technicians, administrators, and medical specialists in the order.

  • The paper suggests to reclassify the casuality accidents types and causes at urban rail stations in the standardized code manner. In order to make standardized codes, 4,086 casuality accidents for Seoul Metro and Seoul Metropolitan Rapid Transit Cooperation (SMRT) are analysed. The standardized code for casuality accident types includes 4 distinct factors; casuality object, casuality location and casuality pattern. Also, the standardized code for casuality accident causes includes 4 distinct factors: casuality trigger, drinking or not, first cause and second cause. This code is deemed to play a big role to link the same casuality accident types or causes which can be used in the process of railroad safety management and emergency response system.

  • This paper presents an efficient method for generating informative apparel fit comments by analyzing 122 fit reviews found in 7 menswear patternmaking textbooks, which include both domestic and foreign sources. The fit reviews for menswear were categorized into top and bottoms, and the expressions varied based on body parts, causes, and fit issue appearances. The causes of fit issues could be attributed to size errors and structural errors in both top and bottoms. Both top and bottoms had fit reviews concerning unique body types, but it could cause trouble among learners as both were based on unclear criteria for body type classification and lacked relevant explanations. Common fit issue appearances included compound wrinkles, pulling wrinkles, sagging wrinkles, and garment being away from the body. No clear correlation was observed between the causes of fit issues and specific appearances. Limitations were identified in using textbooks as educational data, such as inconsistent solutions for different body types or fit issues, and the presence of ambiguous visual materials. As a result, strategies such as categorizing fit issue appearances, providing 3D visual examples with subcategorized causes, body types and parts could enhance quality of fit reviews and improve fit outcomes in clothing production systems.

  • Given the few studies on the responsibilities of assembly, government, and president for social conflicts, this study analyzes the influence of conflict causes upon that responsibilities. First, the need for the mediation mechanisms for dealing with social conflicts and the level of labor-management conflict are positively associated with the responsibilities of assembly, government, and president. Second, the levels of conflict between social strata and ideological conflict are positively related with the responsibility of assembly or president. Third, interdependence and mutual understanding between stakeholder, among independent variables, are positively associated with the responsibilities of assembly and president. Finally, all of the levels of conflict types, except the level of ideological conflict, moderate the effects of conflict causes on the responsibilities of assembly, government, and president. These results reflect the importance of managerial and institutional approaches to the conflict resolution focused on conflict causes and types.
