This paper examines the disciplinary effect of deposits using the semiannual accounting data of mutual savings banks(henceforth 'MSBs') in Korea for the period of 2003 through 2007. I find overall strong evidence in favor of the existence of market discipline in the industry. MSBs with higher BIS ratio and lower NPL ratio turn out to have higher increase rate of deposits than MSBs with lower such ratios. The coefficient of NPL ratio becomes greater with time, suggesting that the effect is cumulative. It turns out that depositors respond more sensitively to NPL ratio than BIS ratio in a period of MSB failure. On the other hand, MSBs turn out to act very positively responding to the depositors' discipline. They increase BIS ratio or decrease NPL ratio following the previous decrease in deposits. Government authorities need to make more efforts to develop a suitable incentive system (e.g. penalties on a false disclosure) to improve the efficiency of disclosure by MSBs. Moreover, they need to acknowledge the importance of NPL ratio as a market disciplinary tool which has been becoming more important, especially in times of MSB failure.

The purpose of this study was to examine the mediating effects of rapport on the relationship between type of organizational culture and innovative behavior of hotel chefs. In order to accomplish the research purpose, data were collected from 202 chefs working at five-star hotels located in Gwangju and Jeonnam areas, and SPSS 22.0 Program was used to conduct frequency analysis, reliability analysis, exploratory factor analysis, regression analysis and mediation effect analysis. The results of the study were as follows. Firstly, it was found that innovative behaviors of hotel chefs are significantly affected by three types of organizational culture: rational culture, consensual culture, and developmental culture. Secondly, it was found that rational and consensual culture have significant effect on rapport. Thirdly, it was found that better-formed rapport in hotel chefs significantly remarkably influences their innovative behavior. Fourthly, the study results revealed that rapport has a mediating effect on the relationship between type of organizational culture and innovative behavior of hotel chefs. Thus, in order to induce voluntary innovative behaviors from building rapport in the hotel organization, it is necessary to develop and implement effective strategies which will form a work environment where chefs can freely engage in mutual exchanges and build trust with one another.

Purpose: This study aimed to identify the actor and partner effects of self-efficacy, marital adjustment, and social support on the health promoting behavior of Korean pregnant couples. Methods: Participants were 132 couples who met the eligibility criteria. Data were collected from June to November, 2016 at a community health center. The Actor-Partner Interdependence Model was used for analyzing the actor and partner effects of self-efficacy, marital adjustment, and social support on health promoting behavior. Results: The fitness indices for the model were GFI=0.90, NFI=0.92, CFI=0.91, TLI=0.90, and RMSEA=0.04, which satisfied the criteria. Self-efficacy had actor and partner effect on health promoting behavior of wives, but had only actor effect of on health promoting behavior of husbands. Marital adjustment showed actor and partner effect on the health promoting behavior of pregnant couples. Social support only had an actor effect on the health promoting behavior of wives. And, marital adjustment and social support had a mutual effect. Conclusion: This study indicates that the partner involvement is needed to develop health promotion programs for pregnant couples.

In this paper, a new CMOS RF model for RF IC design including the capacitance effect, the skin effect, and the proximity effect between metal lines on the Si surface is proposed for tile first time for accurately predicting the RF behavior of CMOS devices. The capacitances between metal lines on the Si surface are modeled with the layout. And the skin effect is modeled with a parallel branch added in equivalent circuit of metal line. The proximity effect is modeled by adding the mutual inductance between cross-coupled inductances in the ladder circuit representation. Compared to the BSIM 3v3. the proposed RF model shows good agreements with the measured data and shows well the frequency dependent behavior of devices in GHz ranges.

This study aims to analyze the mutual influences between adolescents' multicultural acceptability and school adjustment. Research problems for research are as follows. First, is multicultural acceptability and school adjustment stable over time? Second, what is the longitudinal impact of school adjustment on multicultural acceptability over time? Third, what is the longitudinal impact of multicultural acceptability on school adjustment over time? The results of analyzing the research problems by applying the autoregressive cross-lagged model are as follows. First, the autoregressive model of school adjustment has a significant effect on the future time point and is stable over time. Second, the autoregressive model of multicultural acceptability have a significant effect on the future time point and is stable over time. Third, cross-lagged effect from school adjustment to multicultural acceptability has a statistically significant effect on the multicultural acceptability at a later time, and is stable over time. Fourth, cross-lagged effect from multicultural acceptability to school adjustment was not statistically significant at the time of multicultural acceptability, and there was no change with time. This study is meaningful to provide the theoretical and practical implications by verifying the influence of the three - year term data over time.

Rock damage induced by blasting can not be avoided during tunnel construction and may affect tunnel stability. But the mutual interaction between tunnel blasting design and tunnel stability design is generally not considered. Therefore this study propose a methodology to take into considration the results of the blasting damage in tunnel stability design. Rock damage is evaluated by dynamic numerical analysis for the most common blasting pattern adopted in road tunnel. Damage zone is determined by using the continuum damage model which is expressed as a function of volumetric strain. And the damage effect is taken into account by the damaged rock stiffness and the damaged failure criteria in tunnel stability assessment. The extend of plastic zone and deformation increase compared to the case of not considering blast-induced rock damage.

The basic mechanism of the granular sludge formation which is the most important factor in the start-up and stable operators is not confirmed yet. In this study, the effect of granular sludge formation was investigated with the different substrate concentrations and the various ratios of substrate supply/deficiency. The granular sludge formation in the UASB reactor was closely related to the substrate concentrations and the ratio of substrate supply/deficlency The granular sludge formation was not accelerated at low substrate concentration. It was convinced that granular sludge formation was accelerated when the substrate supply with high concentration was stopped at UASB reactor. From this experiment, it was estimated that granular sludge was formed by the combination of hydrogen utilizing bacteria that form hydrogen condition and acid forming bacteria at substrate deficit condition by mutual symbiosis. Though the removal efficiency of organic matter was decreased as the influent substrate concentration was Increased, the higher the influent substrate the better the granular sludge formation.

For computer aided design and costruction of low noisy power plants, indoor and outdoor noise prediction program has been developed. The program utilizes the predefined data of noise sources and building materials and has the faculty to estimate the source level using the empirical formula in case of the measured data not being available. In the noise prediction, the mutual noise propagation between indoor and outdoor sites are considered. The outdoor noise source in the calculation of geometric divergence effects is modelled as the omni-directional finite line or planar source according to the source geometry and the receiving points. Outdoor noise prediction is carried out to consider the diffraction effect due to plant structures as well as the attenuation effect due to atmospheric absorption and soft ground. The results of indoor and outdoor noise prediction for a recently constructed diesel engine power plant show good agreement with the measured.

In this study, the effect of the steering vector model mismatch due to array uncertainties on the performance of array processing was analyzed through simulation, along with the alleviation of the model mismatch effect depending on array calibration. To increase the reliability of the simulation results, the actual steering vector of the array antenna obtained by electromagnetic simulation was used along with the Jahn's channel model, which is an experimental channel model. Based on the analysis of the power spectrum for each direction, beam pattern, and the signal-to-interference-plus-noise ratio of the beamformer output, the performance deterioration of array processing due to array uncertainties was examined, and the performance improvement of array processing through array calibration was also examined.
