To estimate the cooling load for the following day, outdoor temperature and humidity are needed in hourly base. But the meteorological administration forecasts only maximum and minimum temperature. New methodology is proposed for predicting hourly outdoor temperature and humidity by using the forecasted maximum and minimum temperature. The correlations for normalized outdoor temperature and specific humidity has been derived from the weather data for five years at Seoul, Daejeon and Pusan. The correlations for normalized temperature are independent of date, while the correlations for specific humidity are linearly dependent on date. The predicted results show fairly good agreement with the measured data. The prediction program is also developed for hourly outdoor dry bulb temperature, specific humidity, dew point, relative humidity, enthalpy and specific volume.

Objectives : In this study, we researched the change of 'quality of life(QOL)' of patient with panic disorder by KvSBQOL and the predictors affecting the change of 'quality of life'. Methods : 30 outpatient with panic disorder were tested by questionnare for panic disorder and KvSBQOL. Frst, they were classified as when healthy before panic episodes(a point of time 1), when first diagnosed as panic disorder in the psychiatry(a point of time 2), and when treated after diagnosis(a point of time 3). Second, the change of QOL scores in five factors at each point was observed, Third, the correlation between the change of QOL scores(point 3 score-point 2 score) and the several predictors(Onset age, Degree of change in panic symtom, Degree of change in anticipatory anxiety, Degree of change in agraphobia, Spended time to diagnose panic disorder, Duration of treatment) were studied. Results : 1) QOL mean scores of a point of time 1,2 and 3 were 166.267±38.24, 94.367±34.00, 161.367±34.37, respectively. 2) The change of QOL scores in all five factors of KvSBQOL(factor1 Competence, factor2 Psychological well-being, factor3 Stability, factor4 Physical well-being, factor5 Activity)at each point was significant(P<.000). 3) The change of QOL mean scores(point 3 score-point 2 score) have significantly negative correlation with the change of score in anticipatory anxiety but not other predictors. Conclusions : Difference in QOL scores between a point of time 1 and 3 is 4.9, indicating that the psychiatric treatment is important in improvement of QOL, the anticipatory anxiety is an important predictor of QOL(P<.001). and it suggested that diminished anticipatory anxiety is very important to maintain of high QOL in patient with panic disorder.

This study was carried out over two consecutive years to evaluate the effects of polyethylene (PE) film liner, 1-methylcyclopropene (1-MCP), and aminoethoxyvinylglycine (AVG) treatments on fruit quality attributes of ‘Tonewase’ persimmon in cold storage. Fruit was harvested at two different levels of maturity, at a normal commercial harvest date in the first year and 10 days earlier in the second year. The PE film liner treatment significantly suppressed losses of fresh weight during cold storage, compared with the other treatments in both years. However, peel color variables (L*, a*, and b*) in the calyx-end regions declined when treated with the PE film liner, compared with the other treatments in both years. None of the treatments affected ethylene production and fruit decay was not detected during storage between the treatments. The highest level of fruit softening was observed in persimmon fruit treated with the PE film liner, while the softening rate in the other treatments was less than 50% at the end of cold storage. Fruits in all treatments were unmarketable after 2 months of storage. For the persimmon fruit harvested at the normal harvest date, the treatment with 1-MCP resulted in the highest average respiration rate and the lowest soluble solids content (SSC), compared with fruit in the other treatments. For the persimmon fruit harvested at the early harvest date, flesh firmness of fruit treated with the PE film liner declined significantly, but less so than for fruit in the other treatments by the end of storage, whereas the SSC and respiration rate were not affected by any of the treatments during cold storage. The PE film liner significantly reduced fresh weight loss during cold storage and flesh firmness and peel color were significantly affected by this treatment in second year. Overall, the results suggested that fruit harvest time in terms of fruit maturity and PE film liner treatment would retain greater fruit quality attributes during storage.

In an attempt to know the factors affecting the development of agoraphobia following panic attacks, the author investigated whether there are differences between coping strategies of panic disorder with and without ago-raphobia. Thirty-seven patients meeting the criteria of DSM-IV panic disorder were divided into 2 subgroups, one group with agoraphobia, another without agoraphobia. Questionaires for the severity of panic symptoms, and of anticipating anxiety for panic attacks, multidimensional coping scale for stress were administered to panic subjects. The results were summarized as follows. 1) Group of panic disorder with agoraphobia complaints trembling or shaking more than group of panic disorder without agoraphobia. 2) There was no differences of degree for the severity of anticipating anxiety between two groups. 3) Group of Panic disorder with agoraphobia had higher score on BDI than Group of panic disorder without agoraphobia. 4) Group of panic disorder with agoraphobia had lower score on active coping, positive interpretation, acceptance than group of panic disorder without agoraphobia, and the differences of these strategies between two groups were not correlated with the score on BDI at the time of investigation. In conclusion, these results suggest that the coping strategies for stress may be a predictor of agoraphobia in patients with panic disorder.

We investigated the effects of 1-methylcyclopropene (1-MCP, SmartFresh<SUP>TM</SUP>) concentrations on fruit quality attributes associated with softening and cell wall metabolism in ‘Honggeum’ apples. Fruits were treated with 0, 0.5, or 1 μL·L<SUP>-1</SUP> 1-MCP and stored at 0 ± 1°C for up to 6 months. In comparison with the untreated fruits, both 1-MCP concentrations similarly reduced the internal ethylene concentration and delayed the reduction in firmness and titratable acidity; however, weight loss and soluble solids content were less affected by 0.5 μL·L<SUP>-1</SUP> 1-MCP compared with 1 μL·L<SUP>-1</SUP> 1-MCP. Peel color variables (L<SUP>*</SUP> and b<SUP>*</SUP>) were not changed by either 1-MCP treatment on both the sunlit and shaded sides. Only the a<SUP>*</SUP> value on the shaded side was slightly decreased among untreated fruits at 3 and 4 months in comparison with 0.5 μL·L<SUP>-1</SUP> 1-MCP-treated fruits. The uronic acid and total sugar contents of the cell wall and cell wall hydrolase of the enzyme activities (α- galactosidase, β-galactosidase, β-glucosidase, β-arabinosidase, β-xylosidase, and α-mannosidase) were much greater in fruits treated with 1 μL·L<SUP>-1</SUP> 1-MCP than in fruits treated with 0.5 μL·L<SUP>-1</SUP> 1-MCP and in untreated fruits. Overall, the results suggested that 1 μL·L<SUP>-1</SUP> 1-MCP may be an effective concentration to retain fruit quality attributes and delay fruit softening in ‘Honggeum’ apples during cold storage by reducing enzymatic activities related to cell wall hydrolysis.

The engineer"s effort to select a optimized material can cut down the production cost over approximately 10% in design step. The methods selecting optimized material are one by experiment and one by existing research data. In this paper, we studied the procedure and the way of the latter. And STS304L was selected as an optimized material by the cross-check of STS304L and STS316L through the analysis of existing corrosion data. To estimate a life cycle cost(LCC), the design engineer must be enabled to presume the material lifespan due to corrosion. The equation to estimate the LCC should be develop to presume the material lifespan. The variable of the equation should be apply only parameters of a water quality analysis data without experiment ones in order to see the lifespan handily.
