Recently, in-home shopping channel has become a popular shopping channel. This study develops and tests a model of the share and variety of in-home shopping channel. We explore the effects of demographic characteristics and shopping behavior characteristics to the share and variety of in-home shopping channel. As a research methodology, we choose the simultaneous equation model with selectivity to consider both sample selection and effects between dependent variables. The result of study can be summarized as follows. First, there are no effects between the share and variety of in-home shopping channel. Second, the share of in-home shopping channel decreases when consumers visit department store more than discount store. Third, the demographic characteristics and the shopping behavior characteristics don't affect the variety of in-home shopping channel. Some managerial implications for manufacturers and distributors are discussed.

The purpose of this study was to assess dietary variety by body mass index, waist circumference and exercise habits in 138 female university students residing in Bucheon and its adjacent area. Body mass index(BMI), waist circumference (WC) and exercise habits were assessed via a self reporting questionnaire, and a 3-day dietary recall survey was conducted by interviewing. Dietary variety was assessed by dietary diversity score(DDS), meal balance score(MBS), and dietary variety score(DVS). The average BMI, WC, DDS, MBS, and DVS were $20.7{\pm}2.59\;kg/m^2$, $69.3{\pm}5.03\;cm$, $3.87{\pm}0.57$, $7.27{\pm}1.48$, and $12.59{\pm}3.14$, respectively. The DDS for breakfast, lunch, supper and snack were $1.80{\pm}0.92$, $2.45{\pm}0.48$, $2.49{\pm}0.55$ and $0.53{\pm}0.52$, respectively. DDS, MBS, and DVS were not significantly correlated with BMI, WC and exercise habits. However, DDS for breakfast and supper were significantly higher(p<0.05) and lower(p<0.05) respectivly in subjects who exercised regularly compared to those who did not exercise regularly. And DDS for snack was significantly higher in subjects whose awareness of health status was good or somewhat compared to those whose that was bad(p<0.05). These findings suggest that nutritional education based on female university students' eating variety and regular exercise may be required to improved dietary variety.

This paper deals with how Korean television musical variety show rose and declined focusing the 'Show Show Show'. 'Show Show Show' was a Korean television musical variety show that ran on TBC-TV every Saturday night at 8pm. until TBC-TV was absorbed into KBS-TV in 1980. Its musical acts, of various kinds, were interspersed with comic turns and special items including dancing, mime, magic, and acrobat. Korean television musical variety show worked on what audiences had in common across generational divides till the late 1970s. 'Show Show Show's catchall format didn't cross the demographic lines like it used to. But the young generation demanded music program that spoke to their own condition in the early 1980s. 'Show Show Show' ended on KBS-TV in July 1983 through the influence of the absorption of TBC-TV into KBS-TV and the changes of cultural circumstances. The decline of the television musical variety show was attributable to the fragmentation of musical taste and the change of viewing behaviors.

Thirty day old rice seedlings, Ilpoom and Taeback variety, grown under deficient condition of several elements in nutrition solution of sand culture were exposed to 20Gy, 40Gy, 80Gy of gamma ray $(^{60}Co)$ to study the effect of their radiosensitivity. The results obtained are summarized as follows : Plant height and fresh weight of nutrient deficient rice plants were far less than those of control. The effect was different with nutrient element and rice variety, as show increasing effect of radiosensitivity in the Ilpoom variety was high in the Fe deficient whereas that of Taeback was high in the P deficient. Growth inhibition of rice plant irradiated with 20Gy was highly occurred in the Fe and Zn deficient plot in Ilpoom variety and P and Zn deficient plot in Taeback variety. In 80Gy irradiated group, radiosensitivity of rice plant was high in the P and Ca deficient plot of both Ilpoom and Taeback variety.

In order to reduce the problems from the presence of rye crop residues in maize establishment and yield, and also to improve the growth, productivity and nutritive value of rye(Seca1e cereal L.). an experiment was canied out to determine the variety effect of rye on the forage production system and the eft'ect of seeding and harvesting dates on the production and quality of rye. 'This experiment was conducted at the forage testing field of S.N.U., Suweon, from September 1986 to May 1989. Heading date of an early maturing rye variety, Wintermore. was earlier 10 days than that of a late maturing rye variety, Kodiak. A 15-days delay in the seeding dates of early and late maturing varieties of rye tended to delay the heading dates of the rye varieties for 3 and 4 days, respectively. Dry matter and in vitro digestible dry matter yields were markedly increased with earlier seeding date. Before 20 April, the DM and IVDDM yeilds of an early maturing rye variety, Winterrnore. were higher than those of a late maturing rye variety, Kodiak. However, no such a trend was found between the early and late maturing varieties of rye after 27 April. Less than 35% of ADF was recorded until the harvesting dates of 13 and 27 p r i l for early and late maturing rye varieties, respectively, but less than 46% of NDF was maintained until the harvesting drtte of 13 April for botg varieties. Based on the results obtained from this experiment. it may be concluded that the most desirable forage production from corn-rye double cropping system is to advance the seeding time of rye toward the first 10 days of September as well as harvesting time toward the first heading stage with an early maturing rye variety.

Based on the strategic contingency theory, this study empirically examines Korean TV drama producers' changing adaptive behaviors in terms of genre variety given different levels of environmental uncertainty. The extant literature has suggested that firms tend to increase product variety in order to cope with increasing environmental uncertainty. This study attempted to verify the hypothesis that TV drama producers would employ wider variety of genre in the period with more uncertain environment(2003-2009) than the period with stable environment(1994-2002). Empirical results support the hypothesis, implying that TV drama producers tend to repeatedly produce dramas with the same genre in order to pursue efficiency in stable environment whereas they tend to employ a variety of different genre in order to cope with increasing environmental uncertainty.

Cooking and eating qualities of two rice varieties in Korea, an Indica type 'Tongil' and a Japonica type 'Jinheung', were investigated to compare each other. Cooked rice of Tongil variety absorbed $4{\sim}6%$ more water at the same water-to-rice ratio, showed higher mechanical hardness and needed 20% higher water-to-rice ratio to maintain the same hardness as compared with Jinheung variety. Optimum water-to-rice ratios in cooking were shown to be 140% for Tongil and 120% for Jinheung as judged from the reciprocal hardness scale among textural parameters of cooked rice. When the degrees of gelatinization and retrogradation were determined from enzymic digestion, iodine colorimetric method and textural parameters, Tongil variety showed lower degrees of gelatinization and retrogradation than Jinheung variety did. Tongil variety exhibited a higher gelatinization temperature and lower maximum viscosity and breakdown in the amylograms of the rice powder than Jinheung variety did.

This study was performed to evaluate effects of dietary variety scores (DVS) and dietary diversity scores (DDS) on the nutritional quality of the diets of Korean college students, and to examine the association between food group intake patterns and nutritional adequacy. This study examined the relationship of dietary diversity scores (DDS), dietary variety scores (DVS), and food group intake patterns with nutrient intakes using 24-hour recall data (n=.358). The .DDS was calculated from the sum of each of the five food groups consumed as a score of 'I'. DVS was determined by counting the number of food items consumed daily. Food group intake patterns were expressed with the presence or omission of five major food groups-dairy, meat, grain, fruit, and vegetable. The four most prevalent food group patterns and the proportion of the population reporting them were as follows; no dairy and fruit, $23\%;\;no\;dairy,\;20\%;$ no dairy, meat, and fruit, $15\%$; all food groups, $14\%$. Even though the DDS or DVS was higher, the majority of this study population failed to meet the Korean RDA for calcium in both genders and iron in women. Higher DVS scores $(\geq31)$, within all DDS groups, were associated with the largest proportion of individuals consuming more than $75\%$ of the Korean RDA for selected nutrients. The consistency of these results indicates that screening diets to evaluate the overall dietary variety and variety among the major food groups including food group intake patterns provide meaningful information about their quality.
