To enhance application of FPC in food industry, salmon FPC hydrolysates were produced and their functional properties were investigated. Hydrolysates of salmon FPC showed high solubilities ranged from approximately $80\~95\%$. Emulsifying activity index (EAI) values of hydrolysates were higher than that of egg white, however sugar ester showed the highest EAI value of 32.5. Though sugar ester had the best emulsifying stability value $({\Delta}EAI)$ of 9.65, hydrolysates showed better ${\Delta}EAI$ value than that of egg white. Foam Activity of hydrolysates was predominantly better than those of controls and also foam stability value showed similiar trend. Osmolality of hydrolysates was increased with the increase of degree of hydrolysis (DH) and concentration of protein, but it showed very lower osmolality than that of NaCl. Flow property of hydrolysates showed different upward-downward curves, and hysteresis loop increased with the increase of DH. ACE inhibitory activity showed similiar value ranged from $21.1\~24\%$ at all DH values.

Software reliability in the software development process is an important issue. Software process improvement helps in finishing with reliable software product. Infinite failure NHPP software reliability models presented in the literature exhibit either constant, monotonic increasing or monotonic decreasing failure occurrence rates per fault. In this paper, proposes the reliability model with log type mean value function (Musa-Okumoto and log power model), which made out efficiency application for software reliability. Algorithm to estimate the parameters used to maximum likelihood estimator and bisection method, model selection based on mean square error (MSE) and coefficient of determination($R^2$), for the sake of efficient model, was employed. Analysis of failure using real data set for the sake of proposing log type mean value function was employed. This analysis of failure data compared with log type mean value function. In order to insurance for the reliability of data, Laplace trend test was employed. In this study, the log type model is also efficient in terms of reliability because it (the coefficient of determination is 70% or more) in the field of the conventional model can be used as an alternative could be confirmed. From this paper, software developers have to consider the growth model by prior knowledge of the software to identify failure modes which can be able to help.

Rural area development projects are being carried out in a strategy to create new value in agriculture and farm villages and to change the public perception. This study targeted rural experience participants visiting Cheong-Ho region, where the Rural Village Comprehensive Development Project was carried out. They were surveyed about attributes of visits to farm villages to determine which attributes of the experience could influence their revisits. This study was conducted under an umbrella project conducted as per the Special Act on Life Improvement and Regional Improvement for Farmers and Fishermen. Cheong-Ho region in Buan-gun produces mulberry, organic wheat, and rice grown using environmentally-friendly agricultural practices. This region as held events offering visitors the chance to experience rural villages and mulberry farms. Survey results showed that the natural landscape of villages, village experience, and the services provided by residents had a positive relationship with the probability of revisiting the village. Also, village facilities, harmony of natural landscape, hospitality of village residents, amusement value of rural experience, and the cost for rural experience were significant attributes. Therefore, it is necessary to revitalize the rural experience program targeting rural experience participants in Cheong-Ho region through continuous and monitoring of key visit attributes and revisit factors.

Purpose: Under the purpose of presenting the adequate remodeling period for the improvement of thermal insulation performance of external walls in deteriorated buildings, the change in external wall and residential environment problem(dew condensation) due to aged deterioration after the apartments were constructed in Korea were analyzed. Method: Temperature Difference Ratio Outside(TDRo) and Heat Flow Meter(HFM) were used as measurement methods to evaluate the thermal insulation performance of deteriorated buildings. For TDR evaluation, thermo-graphic camera was used to measure and analyze the surface temperature of external wall. Also, dew condensation evaluation was analyzed using the Temperature Difference Ratio Inside(TDRi). Result: As a result of analyzing thermal performance through TDRo, the first decline point of thermal insulation performance began after 14-16 years have passed since construction was completed, and after 20 years have passed the decline point of thermal insulation performance reappeared. As a result of analyzing U-value with HFM measurement method, the decline rate of external wall's thermal insulation performance is lower than 2% in average at around 5 years after completion, and 8.7% in average at 10-15 years, and over 10.2% in average at 20 years.

Man-made reservoirs over 95% in Korea are shallower than 10 meters in depth, which is apt to cause eutrophication. This study has characterized long-term trends in water quality factors for the selected six reservoir points in the Kum River watersheds, and then estimated the seasonal trophic state index for each reservoir. The reservoir trophic state was evaluated at four trophic levels using the Korean trophic state index, TSIKO. It is observed from seasonal results for six reservoirs that the highest value of the trophic state index is estimated in summer while the trophic state index value is low in spring and winter seasons. Especially, the Boryeong Lake has a relatively lower trophic state index since this reservoir has been managed properly for water withdrawal and irrigation. It is expected that the seasonal trophic state index resulted from this study can contribute toward long-term water quality improvement plans for reservoirs.

This paper treats the analytical and experimental studies on the improvement of commutating circuit for the speed control of DC motor. A simple circuit composed of R, L and C elements is proposed here for switching off power SCR carrying the load current. The real important in this chopper circuit is to determine the reasonable values of commutating circuit constants. In this paper, the reasonable values of the commutating circuit constants are basically determined on a view point of commutating performances in the given circuit model and must satisfy the following conditions. The first, the peak commutating current should be larger than the anticipated maximum load current. The second, the circuit turn-off time (tc) must be longer than the SCR turn-off time (tq). The third, the resistor should be enough large to permit the current to be neglected in the analysis of the commutation circuit, as well as be enough small to permit to charge the capacity voltage (Ec) to the half the value of source voltage (E) before the next communication cycle is initiated. The last, the period of chopping signal must be the least possible multiple of the damping vibration period of commutating circuit. The improved chopper circuit used in the experiment under unloaded condition was composed to meet the reasonable conditions mentioned above, and a successful commuting performance was achieved without failure. Several types of microprocessor having a different value of CPU speed individually have been applied to the experiment under the loaded conditions. Also it shows that the faster the speed of CPU is, the more stable the commutation turns out.
