Recently, a long strike by hospital labor union emerged as a serious social issue. During the Worldcup Games in June, 2002, labor strikes broke up at 'C', 'K' and other hospitals, and in 2007, 'Y' hospital suffered much from a strike. Such series of extreme labor disputes have awakened people of importance of a more stable labor-management relationship for the medical institutions responsible for people's health than any other business organization. The purpose of this study was to examine the labor-management disputes at 'Y' hospital in 2007 and 'C' and 'K' hospitals in 2002. The results of this study can be summarized as follows; First, requests of the labor union such as pay raise, reemployment of the irregular workers as regular employees and participation of the labor union in personnel affairs are the long-held or core issues suffered by the medical institutions. Such issues are not independent from each other but complicated with each other surrounding the pay raise. Accordingly, it is not easy to determine the genuine bone of issue for labor-management disputes. Second, the model type of disputes between labor and management at medical institutions may be strike. However, it is conceived that the type of disputes would be subject to change as the essential medical service area system began to be operated since 2008. Third, the common characteristic of the labor strike among the 3 sample hospitals was occupation of the hospital lobby for a sit-in strike to maximize the negative effects of strike. Article 42 (Prohibition of Violence) of Labor Union and Labor Relation Coordination Act prohibits occupation of production or other important business facilities. In addition, since Ministry of Labor interprets that the hospital lobby belongs to the important business facilities enumerated by Article 42 of the above act, occupation of the hospital lobby for a sit-in strike may be too controversial to be admitted as a fair act of labor dispute when its legitimacy should be judged. Fourth, the counter-measures taken by the hospitals against the strike were observance of the principle 'no labor no pay,' closure, legal action, accusation, claim for recovery of damage, provisional seizure, disciplinary punishment, etc., but the principle of 'no labor, no pay' was not applied in a fair manner by 'C' and 'K' hospitals. However, 'Y' hospital applied this principle thoroughly to the strike; the hospital conduced to correction of the wrong labor-management relationship by refusing inclusion in the labor collective agreement of a provision about payment of wage during the period of strike or labor union's request to that effect during a strike. In addition, 'Y' hospital took an effective measure to end the strike earlier by notifying the labor union of cancellation of the collective agreement and banning the unionists from entering the hospital.

신강욱,홍성택,Shin, Gang-Wook,Hong, Sung-Taek 한국정보통신학회 2013 한국정보통신학회논문지 Vol.17 No.12

위성통신설비의 수명은 설비별 사용빈도와 운영환경에 따라 상이하나, 설비 개대체시 내용년수만을 고려하고 있는 실정이다. 따라서, 설비의 성능분석을 통한 상태평가 및 의사결정에 따른 과학적 근거를 기초로 한 경제적인 자산관리가 필요하다. 본 연구에서는 K-water에서 사용하고 있는 위성통신설비에 대하여 물리적 평가, 성능분석 평가, 경제성 평가, 내용년수 평가를 통한 과학적인 상태평가표를 제안하였으며, 이를 통한 합리적인 개대체 방안을 수립하였다. Life time of facilities is different In case of operating environment and frequency of use. So, the durable year of the facilities is only considered to replace the facilities at present. Thus, system management is needed economical assesment based on condition evaluation through performance analysis of facilities. This research makes a proposal for scientific condition evaluation table through physical assessment, performance analysis assessment, durable years assessment about satellite communication facilities being used in K-water. Consequentially, reasonable replacement plan is established for satellite communication facilities.

단기 물 수요예측 시뮬레이터 개발과 예측 알고리즘 성능평가

Generally, treated water or raw water is transported into storage reservoirs which are receiving facilities of local governments from multi-regional water supply systems. A water supply control and operation center is operated not only to manage the water facilities more economically and efficiently but also to mitigate the shortage of water resources due to the increase in water consumption. To achieve the goal, important information such as the flow-rate in the systems, water levels of storage reservoirs or tanks, and pump-operation schedule should be considered based on the resonable water demand forecasting. However, it is difficult to acquire the pattern of water demand used in local government, since the operating information is not shared between multi-regional and local water systems. The pattern of water demand is irregular and unpredictable. Also, additional changes such as an abrupt accident and frequent changes of electric power rates could occur. Consequently, it is not easy to forecast accurate water demands. Therefore, it is necessary to introduce a short-term water demands forecasting and to develop an application of the forecasting models. In this study, the forecasting simulator for water demand is developed based on mathematical and neural network methods as linear and non-linear models to implement the optimal water demands forecasting. It is shown that MLP(Multi-Layered Perceptron) and ANFIS(Adaptive Neuro-Fuzzy Inference System) can be applied to obtain better forecasting results in multi-regional water supply systems with a large scale and local water supply systems with small or medium scale than conventional methods, respectively

영구 여기 조건이 불필요한 직접 적응 극배치 제어기의 설계

신강욱,최홍규,박준열 한국통신학회 1992 韓國通信學會論文誌 Vol.17 No.10

비최소 위상 시스템에 대한 적응 제어 알고리즘의 발전은 제어 법칙에 있어서 발생되는 비정칙성(singularity)에 의하여 제한되어 왔다. 이러한 문제를 해결하기 위하여 직접 적응 제어방식과 간접 적응 제어방식을 사용하여 플랜트 신호에서의 영구 여기(persistency of excitation)를 유발시켜 플랜트의 실제값을 추정하기 위한 추정의 수렴성을 보장하는 방법과 간접 적응 제어방식을 사용하여 영구 여기 조건 없이 가제어성 필요 조건을 만족하도록 추정을 적절히 변형 시키는 방법이 연구되어 왔다. 본 논문에서는 직접 적응 제어방식을 사용하여 영구 여기 조건이 없어도 제어기의 파라메타 추정이 가능하도록 하였으며, 플랜트 파라메타의 추정없이 제어기의 파라메타를 직접 추정하도록하여 추정 알고리즘을 간소화하였다. The development of adaptive control algorithms for possibly nonminimum phase systems has been hampered by singularities that may arise in the control law. To solve this problem, one securing convergence of the estimates to their true values by inducing persistency of excitation in the plant signals using direct adaptive control method and indirect adaptive control method, and another in which the estimates are adequately modified to meet the controllability requirements using indirect adaptive control method, without persistency of excitation. This paper presents an adaptive scheme that achieves regulation without persistent excitation condition using direct adaptive control method and reduces estimation algorithms with direct estimation of controller parameters without estimation of plant parameters.

플랜트 PPI 제어기의 모델 불일치를 위한 제어변수 추정

신강욱,박준열 한국조명전기설비학회 2004 조명·전기설비학회논문지 Vol.18 No.2

공정제어에 있어서, 긴 시간지연은 시스템의 효과적인 제어성능을 기대하기 어렵기 때문에 공정의 모델을 이용한 스미스 예측기와 이를 이용한 PPI 제어기 등이 제안되었다. 그러나, 이들 제어기는 실 플랜트와 모델간에 존재하는 오차 때문에 실제 플랜트에서는 원하는 제어성능을 보장할 수 없다. 따라서, 본 논문에서는 이러한 모델 불일치에 의해 발생되는 오차를 보상할 수 있도록 새로운 제어변수 추정전략을 제시하였다. 또한, 이러한 추정전략은 다양한 사례를 통하여 유용한 결과를 얻었다. In process control, PPl controller including smith predictor was proposed for efficient control method because of the weak performance by the effect of long dead-time. But PPI controller can not guarantee of control performance at real plant because of sensitivity to model mismatch. Thus, In this paper, we presented new control parameter estimation strategy for compensating of model mismatch. The proposed startegy obtained useful result through various cases.

아세안 스마트시티 네트워크에서의 신남방국가 물 정책방향

신남방 10개국은 2018년 11월 아세안 스마트시티 네트워크(ASCN, ASEAN Smart City Network)를 공식 출범하고, 지속가능한 도시 개발을 위한 스마트시티 프로젝트를 강력하게 추진하고 있다. ASCN 플랫폼의 목적은 회원국 간 스마트시티 역량 강화와 협력을 통하여, 스마트시티 개발 실행계획을 마련하고, 실효성 있는 시범도시 프로젝트를 발굴 추진하며, 이를 위해 선진국을 비롯한 다자간 금융기관으로부터 재원지원을 조달하고자 한다. 우리나라를 비롯한 미국, 일본, 중국 등 선진국들은 ASCN 국가와 다양한 분야에서 시범사업을 통한 스마트시티 기술 선점 경쟁을 하고 있다. 따라서, 본 고에서는 ASCN 국가들이 요구하는 시범사업에 대한 요청사항을 분석하고, 특히 물 분야에 대한 협력 방안에 대하여 고찰하고자 한다.
