The procedure of finding operating conditions minimizing qualify loss is proposed with a real industry example. The procedure consists or major two parts - the selection or process variables critical to the response and He determination or operating conditions. The coefficients or ridge regression and the and stores or partial least squares are applied to select important process variables. Functional approach and Non-functional approach are used to find proper operating conditions of important process variables.

For real-time displacement monitoring of large-scale structures, the high-rate (>1 Hz) GPS data processing is necessary, which is not possible even for the scientific GPS data processing softwares. Since the baseline is generally very short in this case, most of the atmospheric effects are removed, resulting in the unknowns of position and integer ambiguity. The number of unknowns in real-time kinematic GPS positioning makes the positioning impossible with usual approach, thus two-step approach is tested in this study.

The paper describes disassemblability evaluation method using axiomatic approach. In recent industry, it is necessary to develope high recyclable environmental product due to green consumer and environmental regulations. Disassembly stage is prior to recycling. Disaassembly time data is determined previously in order to calculate the disassembly segments and disassembly sequence. In this paper the evaluation method of disassembly segment/sequence and disassembly time database are suggested. A case study of monitor product was showed.

This study presents a methodology for the system reliability analysis of cracked structures with random material properties, which are modeled as random fields, and crack geometry under random static loads. The finite element method provides the computational framework to obtain the stress intensity solutions, and the first-order reliability method provides the basis for modeling and analysis of uncertainties. The ultimate structural system reliability is effectively evaluated by the stable configuration approach. Numerical examples are given for the case of random fracture toughness and load.

The attention of case management currently has been highlighted and its importance has been highly emphasized in mental heath field. At this point, We conducted a qualitative study on the experience of case managers from the Suwon Community Mental Health Center where it has implemented the ACT model. Through the result of this study, we verified feasibility of ACT model into Korea. and it has shown that assertive service and team approach has been a critical ingredients of ACT and it extended case manager's ability and brought improvement in relationship between clients and them. the clients has brought a positive changes. However case managers have experienced the dilemma between experts initiatives and clients dependency, and they empathised the importance of the familism and mental health system in Korea. In order to implement ACT extensively, we suggested several implications.

This study examined the relationships among the case management implementation factors, client satisfaction and quality of life among the persons with mental illness. The survey and interviews were conducted to the 18 community-based mental health service agencies which were implementing case management, and the 381 mentally ill persons who were living in the community and were receiving services from the agencies. The path analysis and the hierarchical linear modeling were used to examine the association among the independent, mediator, and dependent variables. The major finding of this study were that the caseload had the direct relationship with the quality of life. The case management team approach had the direct relationship with the client satisfaction. The suggestions were made that more focus should be on the maintenance of the appropriate caseload, the increase of the number of the case manager, and the team approach.

The purpose of this study is to analyze the effect of risk efficiency, financial decisions, and financial performance on firm value due to advances in financial reporting technology. This research was conducted on all banking sub-sector companies listed on the Indonesian capital market during a period of eight years, namely 2012-2019 which were selected using the purposive sampling method. The advancement of financial reporting technology is measured by two indicators based on the Internet financial reporting approach. Risk efficiency is measured using three indicators with a risk proxy relative efficiency approach using value at risk. Financial decisions are measured by two indicators that represent funding decisions and investment decisions. Financial performance is measured by two indicators with the profitability approach, and firm value is measured by two indicators based on the investor perception approach. The data analysis technique in this study used multivariate analysis with SEM-PLS. The empirical findings of this study are the advances in financial reporting technology, financial decisions, and risk-based efficiency value have a significant effect on firm value, while financial performance does not have a significant effect on firm value. Banking companies reduce risk to achieve efficiency and result in lower profits.

Strategic agility plays an important role in maintaining a competitive advantage for companies, where information systems are introduced. The purpose of this study is to analyze the impact of the introduction of the information system on the strategic agility of the company through the analysis of the "H" resort, which has recently built the information system. Research shows that the introduction of resort management information systems promotes the level of strategic sensitivity, collective commitments and resource liquidity, which are key elements of strategic agility. This study confirmed that the establishment of resort information system has a positive effect on practitioners who want to create strategic agility. However, this study is a single case study and it is difficult to argue that the introduction of information systems is a positive for the strategic agility approach.

In recent decades, the independence and identical distribution (iid) assumption for extreme events has been shown to be invalid in many cases because long-term climate variability resulting from phenomena such as the Pacific decadal variability and El Nino-Southern Oscillation may induce varying meteorological systems such as persistent wet years and dry years. Therefore, in the current study we propose a new parameter estimation method for probability distribution models to more accurately predict the magnitude of future extreme events when the iid assumption of probability distributions for large-scale climate variability is not adequate. The proposed parameter estimation is based on a metaheuristic approach and is derived from the objective function of the rth power probability-weighted sum of observations in increasing order. The combination of two distributions, gamma and generalized extreme value (GEV), was fitted to the GEV distribution in a simulation study. In addition, a case study examining the annual hourly maximum precipitation of all stations in South Korea was performed to evaluate the performance of the proposed approach. The results of the simulation study and case study indicate that the proposed metaheuristic parameter estimation method is an effective alternative for accurately selecting the rth power when the iid assumption of extreme hydrometeorological events is not valid for large-scale climate variability. The maximum likelihood estimate is more accurate with a low mixing probability, and the probability-weighted moment method is a moderately effective option.
