다의성이 있는 용어를 색인어로 사용하게 되면 탐색자의 요구와 관계없는 주제가 검색되므로 잡음률이 높아지게 된다. 이를 방지하기 위하여 거의 모든 통제어휘시스템에서 색인어로 사용될 기입어가 다의성을 가질 때 한글, 한자, 외국어 등을 이용하여 동형이의어와 세부분야을 한정하고 있다. 그러나 여러 학문분야에 걸친 대단위 어휘사전을 구축하려고 할 때 이들을 이용하여 다의성을 해소하는 데는 미흡한 점이 많으며, 흔히 사용하고 있는 한자한정어도 많은 문제점을 안고 있다. 본 고에서는 색인어로 사용될 기입어가 다의성이 있을 때 한글 한정어를 부기하여 이들을 구별할 것을 제안한다. 한글한정어의 타당성, 사용범위, 사용원칙등에 대하여 시소러스를 중심으로 논하고 이 개념의 확대적용방안에 대하여 언급한다.

This paper presents assessment of possibility on the human risk for the electromagnetic field of unbalanced two coupled three-phase transmission line using fuzzy theory. Three phase load flow program was developed which employed a Newton-Raphson method as a tool to analyze system unbalanced. This research presents a method of handling two coupled three phase transmission system unbalance analysis and unbalanced power demand as a function of voltages. As the results of case study, in case of 345[kV] T/L, the electric field intensity was 10.9540[kV/m], magnetic field intensity was 0.2567[G] in severest case. The results showed that the membership of a proposition fuzzy '10.9540 [kV/m] is hazardous' is 0.6349. As the analytic results using the fuzzy qualifier term, the membership in case of very false is 0.1379 and fairly false is 0.6124, respectively. In assessment of fuzzy measure possibility for the electromagnetic field, this paper used probability of fuzzy arid measure of fuzziness technique.

In this paper, we propose a 4-step inference method needed for constructing a natural language communication system. The method is used to obtain fuzzy quantifier Q′when QA is Fisr τ⇔ Q′(m′A) is mF is m"is τ is inferred (Q, Q′: quantifiers, A: fuzzy subject, m′, m": modifiers, y: fuzzy predicate, τ: truth qualifier). We show that Q′is resolved step by step for two types of Q, including a non-increasing type (few,...) and a non-decreasing type(most,...).

Purpose: The purpose of this study is to analyze the home-stay disability's activity, as well as the participation domains and the environment factor domains of international classification of functioning (ICF), in order to examine the effect of the home visiting physical therapy and the disability's activity. Methods: A total of 211 home-stay disabled subjects with brain lesions or crippled disorder, living in 5 cities and districts of Jeollanam-do, underwent 90 minutes of home visiting physical therapy per week during a 6-month period, and using the ICF checklist, evaluated the subject's activity and participation domains and environmental factor domains. Results: The performance qualifier showed a significant statistical change in the movement, self-care, domestic life, interpersonal interactions and relationships, community, society and civic life domains (p<0.05); and the capacity qualifier showed a significant change only in the mobility domains in the before and after of the home visiting physical therapy (p<0.05). The barrier factor in the order of services, systems and policies domains, product and technology domains, and attitude domains it influenced significantly in the performance (p<0.05), and in the facilitator factor in the order of product and technology domains, support and relationships domains, services, systems and policies domains it influenced significantly in the performance of the disabled (p<0.05). Conclusion: The visiting physical therapy can help in the improvement of the activity and participation of the home-stay disabled subjects, and for the accurate evaluation of the home-stay disabled subjects, it is considered that an evaluation including various environmental factors, such as ICF, must be fulfilled.

Purpose: The aim of this study was to investigate the effects of coordinative locomotor training in a chronic stroke patient. Methods: A left hemiplegic patient diagnosed with a right middle cerebral artery stroke participated in this research. The patient's functional conditions were assessed, and a coordinative locomotor training program was initiated to resolve the problems identified. A set of movements deemed difficult based on the brief International Classification of Functioning, Disability and Health core set for stroke and d4501 (long-distance walking) were agreed as improvement targets. The program comprised warm up, main, cool-down, and home exercises. Repeated measurements were obtained, as follows: five times at baseline (A), 10 times during the intervention (B), and five times after the intervention (A). The study period was 7 weeks, and the intervention period was 1 h per day, twice a week for 5 weeks. Various tools, including the community walking test (CWT), 10-m walking test (10 MWT), 6-min walking test (6 MWT), and timed up and go (TUG) test, were conducted to assess the patient's walking ability. Changes in functional domains before and after the ICF Qualifier were compared. The mean values of the descriptive statistics were calculated, and a visual analysis using graphs was used to compare the rates of change. Results: The results showed that the CWT, 10 MWT, 6 MWT, and TUG test scores during the intervention period improved and that this improvement remained, even during the baseline period. In addition, the ICF Qualifier before and after the comparison decreased from moderate to mild. Conclusion: Based on the results, we propose that coordinative locomotor training can have positive effects on community ambulation of chronic stroke patients.

Multi-crew Pilot License (MPL) is an international pilot certification adopted by the International Civil Aviation Organization (ICAO) in 2006 under the recognition of the need for efficient and systematic pilot training including the education of pilots with advanced aviation technology and ability to respond to flight environment, resolution of the human factor problems of pilots, and provision of stable training tools for transport aircraft pilots for potential risk of pilot shortage in the future. South Korea also has prepared a legal basis for operating an MPL system in the Aviation Act in 2009, but there has been no domestic MPL qualifier. The biggest reason for this seems to be the insufficient domestic MPL training system. Therefore, it is necessary to benchmark the international standards of the ICAO, and to promote the development of the Korean MPL training system through revision and supplementation of laws and regulations in consideration of Korean circumstances.

The coronavirus pandemic of 2019-20 confronted fiscally dominant regimes around the world with the question of whether the large deficits caused by the health crisis should be monetized or financed by issuing debt. The unpleasant monetarist arithmetic of Sargent and Wallace (1981) states that in a fiscally dominant regime tighter money now can cause higher inflation in the future. In spite of the qualifier 'unpleasant,' this result is positive in nature, and, therefore, void of normative content. I analyze conditions under which it is optimal in a welfare sense for the central bank to delay inflation by issuing debt to finance part of the fiscal deficit. The analysis is conducted in the context of a model in which the aforementioned monetarist arithmetic holds, in the sense that if the government finds it optimal to delay inflation, it does so knowing that it would result in higher inflation in the future. The central result of the paper is that delaying inflation is optimal when the fiscal deficit is expected to decline over time.
