최근 건설산업은 구조물의 일부 또는 전체를 대상으로 제조업의 체계적인 생산시스템인 공장생산방식을 활용하여 생산성을 향상시키기 위한 방안을 마련하고 있다. 하지만 효과를 검증하지 않고 무조건적으로 공장생산방식을 도입한다면 생산 규모와 위치에 따라 현장생산보다 공사비용이나 공기가 증가되는 경우도 있다. 공장생산방식을 보다 효과적으로 활용하기 위해서는 공장생산방식과 현장생산방식을 다양한 기준으로 비교해본 후 적용여부에 대한 의사결정이 이루어져야한다. 본 연구는 기존의 연구와 사례분석을 통하여 공장생산방식의 적용에 필요한 의사결정요인을 도출하고 이를 고려한 의사결정모델을 제시하고자한다 크게 3단계의 연구방법을 거쳐 의사결정을 내릴 수 있는 의사결정순서도와 의사결정모형도를 작성하였다. (1) 공장생산방식 적용 의사결정요인을 도출하고 구조화하여 (2) 공장생산의 규모와 공장의 위치의 변화에 따른 이익, 비용, 공기를 산출한 후 (3) 현장생산방식과 공장생산방식을 반복적으로 비교함으로써 의사결정을 내릴 수 있는 모델을 제시하였다.

본 논문에서는 미리 정의된 키 피쳐(key feature)를 수신된 변조 신호로부터 추출하여 동등 이득 조합(equal gain combining) 기법을 적용하는 자동 변조 인식 알고리즘을 제안하곡 의사 결정 이론(decision-theoretic) 알고리즘과 제안된 알고리즘의 성능을 비교, 분석하였다. 제안된 변조 인식 알고리즘은 키 피쳐 추출 단위인 세그먼트별로 미리 정의된 5 가지 종류의 키 피쳐를 추출하고, 전체 프레임에 걸쳐 평균화된 각 키 피쳐값을 결정-순서도(decision flowchart)에 적용하여 수신 신호의 변조 형식을 구분한다. 제안된 알고리즘의 성능을 검증하기 위하여 아날로그 변조 신호인 AM, FM, SSB 신호와 디지털 변조 신호인 FSK2, FSK4, PSK2, PSK4 신호를 대상으로 SNR의 변화 및 신호 수집 시간의 변화에 따른 변조 인식 성공률을 측정하였다. 그 결과 제안된 알고리즘이 기존의 의사 결정 이론 알고리즘에 거의 근접하는 성능을 나타내면서 낮은 복잡도를 나타내었다.

The objective of this paper is to propose a brand new interface mechanism to provide more intelligent decision making support for EC problems. Its main virtue is based on a numerical process mechanism by using an Extended AND-OR Graph (EAOG)-based logic algebra. Using this mechanism, decision makers engaged in electronic commerce (EC) can effectively deal with complicated decision making problems. In the field of traditional expert systems research, AND-OR Graph approach has been suggested as a useful tool for representing the logic flowchart of the forward and/or backward chaining inference methods. However, the AND-OR Graph approach cannot be effectively used in the EC problems in which real-time problem-solving property should be highly required. In this sense, we propose the EAOG inference mechanism for EC problem-solving in which heurisric knowledge necessary for intelligent EC problem-solving can be represented in a form of matrix. Finally, we have proved the validity of our approach with several propositions and an illustrative EC example

The pump/motor selection program for optimized selection of regional water supply facilities was developed based on a flowchart compiled from basic operational data, total head requirement, initial pump/motor specification selection etc. This program was developed in Visual Basic. The program accepts, as in the flowchart, operational requirements of pumps and other system requirements, and calculates specific speed based on flow rate, total head and rotational speed. Then the calculated specific speed is used to select pump types and speed prior to determining likelihood of cavitation occurring at the calculated NPSH. Power requirement is then calculated for safe operation of pump to assist final pump selection. Test results of the program match very closely to the design values of Paldang intake pump station(3rd stage) proving that the program can be used as an effective and practical aid for designing new regional water supply systems.

The 2020 American College of Cardiology focused update on the mitral regurgitation (MR) pathway provides an excellent summary of the decision-making trees in the treatment of severe MR, in which 2 main branches of the flowchart are suggested depending on whether MR is primary or secondary. Surgery is suggested as preferable over transcatheter edge-to-edge repair (TEER) in primary MR that needs intervention. The decision-making for secondary MR generally prioritizes TEER over surgery according to the guidelines, but further stratification is necessary based on the pathophysiologic mechanisms of MR. TEER is probably the more suitable option in secondary MR caused by left ventricular dysfunction or dilatation, given the high perceived surgical risks, despite the lack of sufficient evidence in support of overt clinical benefits from surgical therapy in these patients. In atrial functional MR associated with atrial fibrillation (AF), however, concomitant ablation of AF seems to be a desirable option, as it has been demonstrated to be a key factor leading to improved survival, reduced stroke risk, and more durable mitral and tricuspid function in patients undergoing mitral surgery. Therefore, atrial functional MR requiring intervention may be best treated by surgical therapy that combines mitral repair and AF ablation in the majority of patients. This particular issue, however, needs further research to obtain scientific evidence to guide optimal management strategies.

As the demand for natural and beautiful smiles increases, the demand for anterior aesthetic treatment is increasing. Orthodontic treatment is often necessary for esthetic, healthy and natural treatment outcome. Particularly, in the case of middle-aged patients, minor tooth movement limited to anterior teeth is more effective than comprehensive orthodontic treatment which requires a long-term treatment period. Clinician who is in charge of aesthetic dentistry should have the ability to select a case that can be treated with partial orthodontic treatment and to determine the most effective treatment method. This article provides decision flowchart for case selection and choosing the best treatment modality for anterior teeth alignment.

This study was designed to investigate purchasing and post-purchase behaviors of middle-aged wives in buying townwears, an well as to examine socio-demographic variables, physical variables, psychological variables, and their influences on. The data included 374 housewives in Seoul and Pusan. Statistics used for data analysis were Frequencies, Means, Standard Deviation, t-test, ANOVA, Pearson's Correlation. The major finding are as follows: 1. The level of post-purchase satisfaction marked higher than middle point. 2. Post-purchase satisfaction differed significantly in income, health-state, identity, stress perceptivity, income satisfaction, sense of comparison, and propensity to consume.

All kinds of commerces are begun from the contract and the claims are frequently raised by the problem in the contracts. Therefore, the negotiation is very important to make a contract and resolve the claim. This article analyzed the negotiation practice of Chinese in order to render help to negotiators who enter into negotiations with Chinese business people so that they can enhance their chance for success. Based on this examination on the negotiating style, this paper also provides the some guidelines in working-level negotiating with Chinese. For the purpose this study applies "global negotiation flowchart" and twelve important factors suggested by stephen & stripp to analyze the characteristics of Chinese business negotiating style. The results suggest some useful criteria for negotiators First, In the preparation, the negotiator need a thorough study about the Chinese negotiating style and counter party. Second, In the negotiation with the Chinese, making the personal relationship and, if possible, frequent contact with the person who is the most powerful negotiator in decision-making. Third, since the Chinese has a sense of value that money is very important, it is very necessary that the negotiator persuade him by mutual profits. Finally, negotiators must aim at long-term profit maximization not at short-term.

Accurate diagnosis of movement disorders is important for providing right patient care at right time. In general, assessment of motor impairment relies on clinical ratings conducted by experienced clinicians. However, this may introduce subjective opinions into scoring the severity of motor impairment. Digital devices such as table PC and smart band with accelerometer can be used for more accurate and objective assessment and possibly helpful for clinicians to make right decision of patient's states. In this study, we introduce quantification algorithms of motor impairment which uses the digital data acquired during four clinical motor tests (Line drawing, Spiral drawing, Nose to finger and Hand flip tests). The step by step procedure of quantifying metrics (Tremor Frequency, Tremor Magnitude, Error Distance, Time, Velocity, Count and Period) are provided with flowchart. The effectiveness of the proposed algorithm is presented with the result from simulated data (normal, normal with tremor and slowness, poor with tremor, poor with tremor and slowness).
