This study examined the degree of socioeconomic deprivation in the areas of material hardship, health, housing, employment, and social network among people using debt relief programs. The sample, 209 individuals, was recruited from major agencies offering debt relief programs, including Seoul Bankruptcy Court, Credit Counseling and Recovery Service, and Seoul Welfare Foundation. Data were collected through in-person interviews in 2016. The sample was compared in terms of the level of deprivation with the general population and the low-income group, extracted from the Korea Welfare Panel Study. The debtors group demonstrated a substantially higher level of deprivation on all the dimensions examined. For example, the proportion of people who suffered from hunger was 37.8% in the debtors group compared to 6.7% in the low-income group. The proportion of people who had suicidal ideation in the last 12 months was 57.9% compared to 19.2% in the low-income group and 2.7% in the general population. The level of deprivation was different by chapter choice of consumer bankruptcy. Policy and practice implications of the results were discussed.

The purpose of this study is to investigate the influence of techno-overload and techno-invasion on emotional exhaustion and the mediating role of psychological contract breach. In addition, this study examines the moderating role of voice behavior in the relationship between techno-overload, techno-invasion and psychological contract breach. The results from 296 participants provided evidence that (1) techno-overload and techno-invasion are positively related to psychological contract breach, (2) psychological contract breach is positively related to emotional exhaustion, (3) psychological contract breach partially mediates the relationship between techno-overload, techno-invasion and emotional exhaustion, (4) voice behavior moderates the relationship between techno-overload, techno-invasion and psychological contract breach. Based on the results, implications of these findings, limitations, and future research are discussed in general discussion.

This study was carried out to understand the characteristic relations fruit changes caused by adjusting the amount of the fruit load in 'Niitaka' and 'Whangkeumbae'. The average fruit weight of 'Niitaka' was 672.0 g and the amount of fruit in the range of 601-750 g was the highest, accounting for 33.8% of the production and as for 'Whangkeumbae', the average fruit weight was 477.5 g and fruit in the range of 401-600 g accounted for 72.5% of total production. The weight of the 'Niitaka' was evenly distributed in each range from below 300 g to over 1 kg and the percent of the regular shaped fruit in 'Whangkeumbae' was high as the distribution range of the fruit weight was narrow. The brix degree and the soluble solid content (SSC)/acidity ratio of 'Niitaka' had a significantly positive correlation with the fruit weight, the length, and the diameter of the fruit. The brix degree also had a positive correlation with weight and diameter of the fruit for 'Whangkeumbae'. As for the difference in fruit quality according to fruit weight for each variety, the brix degree was low in 'Niitaka' that were below 451 g and the fruit firmness was low in fruits weighing under 400 g. There was no difference according to fruit weight in 'Whangkeumbae'. The fruit size was impacted by the fleshy part and the ratio of fleshy part was higher as the fruit size became larger. The weight of the fruit, brix degree, and the SSC/acidity ratio were low while the firmness was high in light thinning treatment for 'Niitaka' and in the case of 'Whangkeumbae', the fruit weight and brix degree were both low in light thinning treatment. The brix degree was higher in bigger sized fruit in all thinning intensity for 'Niitaka', the case in light thinning treatment especially where the quality was poor due to low brix degree in fruits that weighed less than 450 g, on the other hand, there was no difference in the quality due to the fruit weight among the thinning intensity for 'Whangkeumbae'. Therefore, it is possible to produce smaller sized fruits in 'Niitaka' by controlling the thinning intensity, as it is inevitable to result in lower quality fruits, however, it is projected that we can produce small to mid-sized fruits in 'Whangkeumbae' by controlling the thinning intensity without causing the decline in fruit quality.

This study was conducted to evaluate the influence of fruit setting order by flower cluster on the fruit weight and the soluble solids content for the strawberry of 'Seolhyang' cultivar. The first flower cluster had higher fruit number, fruit weight, soluble solids content and ratio of large fruit compared to the second and third flower cluster. The fruit set on the upper position fruit in the same flower cluster had higher fruit weight and the soluble solids compared to the fruit set on the lower position fruit in the flower cluster. The fruit weight was highly positive correlated with the soluble solids content. The result indicated that the number of fruit set for marketable yield seemed to be 9-10 per the first flower cluster, 6 per the second flower cluster, 4 per the third flower cluster and 3 per the fourth flower cluster in 'Seolhyang' cultivar.

'Hanareum' pear is expected to produce the high quality small and medium-sized fruits without any major changes in the current cultivation techniques, inasmuch as its basic characteristics are already included in the range of small and medium-sized fruits. Thus, we tested the possibility of utilization of 'Hanareum' pear for producing small and medium-sized fruits, while establishing the limit of minimum fruit weight for the fruits in high quality. With the results of correlation analysis, it was possible to predict the fruit weight through the observation of soluble solid contents and flesh firmness, because both factors were closely correlated to fruit weight in all treatments. Moreover, these factors were confirmed to be useful indicators of forecasting consumer preference in the sensory evaluation. The fruit marketability was excellent under the conditions that were greater than $11.6^{\circ}Bx$ and less than 25.6 N for soluble solid contents and flesh firmness, respectively. When applying these standards of fruit quality to the results of regression analysis for fruit weight, non-treated fruits fulfilled both standards when the fruit weight was higher than 436 g, and the quality uniformity was also high on this state. Therefore, the production of high quality small and medium-sized fruits was determined to be under this condition. The weight limit for GA treated fruits was 620 g, and both fruit quality and uniformity were below the weight range of small and medium-sized fruits, with 300~500 g. Thus, GA treatment was suggested to be avoided, in order to produce the high quality small and medium-sized fruits.

This study was to compare year variations of heritability, phenotypic, genotypic and environmental correlations as well as pathway coefficients for main characters of tea tree to provide useful selection information for improving tea tree. The data collected from the performance yield trials from 1979 to 1981 were used in this study. I. The genetic variance of fresh fruit yielding, dryed fruit yielding and fresh weight of root was not only greatly varied with year, but also the largest among all characteristies studied. Other characteristics showed higher genetic variance than environmental variances, and year variances were not large. 2. Both year and variety x year interaction were highly significant sources of variation for all yield characteristics, and year variances were not large. 3. All characteristics showed high broad sense heritabilities, and the broad sense heritability was not varied with year. 4. The genetic correlation coefficients between fresh fruit yielding and dryed fruit yielding, fresh weight of root and Gigolpi, dryed weight of root and Gigolpi were positive, and the year variation was not large. S. The pathway coefficients of the character was not only greatly varied with year and the fresh weight of root affected directly on the Gigolpi.

Factors affecting fruit conformation of 'Fuji' apples (Malus domestica Borkh.) were investigated through correlation study of fruit weight, seed numbers, and seed weight in relation to fruit conformation indices. Apples were harvested from two orchards in 'Andong' and 'Youngyang' areas at commercial maturity and grouped by fruit weight. Average number of seeds and seed weight were 8.9 and 0.64 g in 'Andong' orchard, while 6.3 and 0.47 g in 'Youngyang' orchard, respectively. When pooled data from the both orchards were analyzed, correlation of fruit weight with seed weight was significantly positive, whereas that with seed number was not significant. Fruit shape index determined by length/diameter ratio was positively correlated with fruit weight, while relationship of the shape index with seed number or with seed weight was not significant. Asymmetry index tended to be low in apples from the 'Andong' orchard in which higher seed numbers and seed weight were observed. The asymmetry index showed highly negative correlations with seed numbers and with seed weight.

This study was carried out to investigate the effects of planting density, time and frequency of pinching on growth and yield of Lycium chinese Miller cultivated in vinyl house. This experiment was conducted at the experimental field of Cheong-yang Agriculture High School, Cheong-yang, Chung-nam province, in 1997 to 1998. The number of flowers, fruit setting number and dry weight of fruits per branch were increased as the spacings were wider, but the fruit yield per unit area was decreased up to the narrowest spacing plot of $60\;{\times}\;20cm$. The good results of growth status and fruit yield was obtained at the early pinching in May 5. As the more frequent pinching were treated, the more number of flowers and fruits per branch were produced, showing increase of fresh and dry yield, because of much more branches per plot.
