Purpose : To investigate the blood pharmacokinetics and bio-distribution of DTPA-bis-amide (L3) Gd(III) complexes. Materials and Methods: The pharmacokinetics and bio-distribution of Gd $(L3)(H_2O){\cdot}nH_2O$ were investigated in Sprague-Dawley rats after intravenous administration at a dose of 0.1 mmol Gd/kg. The Gd content in the blood, various tissues, and organs was determined by ICP-AES. Blood pharmacokinetic parameters were calculated using a two-compartment model. Results: The half-lives of ${\alpha}$ phase and ${\beta}$ phase Gd $(L3)(H_2O){\cdot}nH_2O$ were $2.286{\pm}0.11$ min and $146.1{\pm}7.5$ min, respectively. The bio-distribution properties reveal that the complex is mainly excreted by the renal pathway, and possibly excreted by the hepatobiliary route. The concentration ratio of Gd (III) was significantly higher in the liver and spleen than in other organs, and small amounts of Gd (III) ion were detected in the blood or other tissues of rats only after 7 days of intravenous administration. Conclusion: The MRI contrast agent Gd $(L3)(H_2O){\cdot}nH_2O$ provides prolonged blood pool retention in the circulation and then clears rapidly with minimal accumulation of Gd(III) ions. The synthesis of gadolinium complexes with well-balanced lipophilicity and hydrophilicity shows promise for their further development as blood pool MRI contrast agents.

This experiment was carried out to compare growth and fruit setting characteristics in ten winter-planted paprika (Capsicim annuum L.) cultivars. Five red line paprika cultivars ('Maduro', 'Maranello', 'Nagano', 'Sirocco' and 'Special') and five yellow line paprika cultivars ('Coletti', 'Sven', 'Thialf', 'Volante' and 'Zagato') were used for this study. The experiment was performed for 42 weeks, from winter of 2013 to autumn of 2014. Based on the growth stages of paprika, growth characteristics were investigated six times, and each investigation was categorized from group 1 through group 6. The relative internode ratio showed a normal range at the early growth stage, but tended to gradually decline as growth progressed. This trend was greater in red line paprika than in yellow line paprika. Among the cultivars used for this experiment, 'Special' and 'Zagato' showed growth inhibition, whereas 'Maranello' and 'Volante' kept a balanced growth during summer cultivation. The fruit set percentage in yellow paprika was 10.8% higher than in red paprika, while the number of branches in yellow paprika was 4.1% less than in red paprika. When measured after the full fruiting age, from June to July, the number of fruit set in group 4 was much lower in 'Sirocco' and 'Coletti' than in any of the other cultivars, indicating that they were more sensitive to the growth environment during the rainy season. These findings suggest that 'Maranello', 'Nagano', 'Sven', 'Thialf', and 'Volante' could be effectively used for summer cultivation in a high-plastic-film greenhouse, and 'Maranello', 'Special', 'Volante', and 'Zagato' could be good candidates for a low-plastic-film greenhouse.

Organization and management scholars have researched social enterprises as hybrid organizations. However, research on the organizational uniqueness of social enterprises as hybrids is limited, especially comparing their organizational characteristics with other traditional types of organizations. Thus, this study attempted to compare social enterprises with traditional for-profit and not-for-profit organizations in the aspect of their organizational hybridity by using the data of the Social Value Survey. The results showed that the orientation of social enterprises in pursuing dual values is weaker than the other two types of organizations. Meanwhile, the results revealed that the extent to which an organization operates for realizing dual values is strongest in social enterprises among the three types of organizations. These findings add to the understanding of social enterprises' organizational hybridity in organization and management studies.

Modern society is an age of vagueness and confusion. In addition, vagueness, complexity and variety are seen throughout art including modern philosophy, literature, and environmental design. A phenomenon like this shows that modern society has integrated different components as an organic relationship frequently crossing the boundary of fields. This feature can be regarded as hybrid related with accepting contradictory components and binding them into one under relationship between part and whole. As new design concept, presented are attitude to accept the two instead of attitude to select one of the alternatives, abundance instead of dearness, and ambiguity instead of simplicity. This principle has a crucial influence on creative design providing opposing contradiction and several alternative plans as non-deterministic form not completed one and, above all, useful information in mutual dependence and mutual relationship. When it comes to hybrid, therefore, a strategy is needed to consider layer of several fields getting out of standardizing space into a single space. As an event of this situation and concept, space experience means behaving freely based on experience of users' body. It can be known that this experience brings about users' more dynamic experience in comparison with the experience of seeing environmental design from a viewpoint of visual ism on the existing simplicity. Such a practical experience is subjective, synesthetic, and non-observational one. Therefore, hybrid has brought active users to the stage, which is distinguished from synesthesia felt through body's experience, not through observational attitude and visual space which achieve former balance and harmony with non-determination. That's because hybrid creatures are turning to a product resulted from creative imagination instead of from reappearance which makes text visualized. Such experience performed by user's active participation collapses the boundary between special elite-centered art and daily life and it is the present progressive form showing creation process of future events and new esthetic experience.

Regardless of the recent observed warmer winters in Korea, more freeze injuries and associated economic losses are reported in fruit industry than ever before. Existing freeze-frost forecasting systems employ only daily minimum temperature for judging the potential damage on dormant flowering buds but cannot accommodate potential biological responses such as short-term acclimation of plants to severe weather episodes as well as annual variation in climate. We introduce 'dormancy depth', in addition to daily minimum temperature, as a complementary criterion for judging the potential damage of freezing temperatures on dormant flowering buds of grape vines. Dormancy depth can be estimated by a phonology model driven by daily maximum and minimum temperature and is expected to make a reasonable proxy for physiological tolerance of buds to low temperature. Dormancy depth at a selected site was estimated for a climatological normal year by this model, and we found a close similarity in time course change pattern between the estimated dormancy depth and the known cold tolerance of fruit trees. Inter-annual and spatial variation in dormancy depth were identified by this method, showing the feasibility of using dormancy depth as a proxy indicator for tolerance to low temperature during the winter season. The model was applied to 10 vineyards which were recently damaged by a cold spell, and a temperature-dormancy depth-freeze injury relationship was formulated into an exponential-saturation model which can be used for judging freeze risk under a given set of temperature and dormancy depth. Based on this model and the expected lowest temperature with a 10-year recurrence interval, a freeze risk probability map was produced for Hwaseong County, Korea. The results seemed to explain why the vineyards in the warmer part of Hwaseong County have been hit by more freeBe damage than those in the cooler part of the county. A dormancy depth-minimum temperature dual engine freeze warning system was designed for vineyards in major production counties in Korea by combining the site-specific dormancy depth and minimum temperature forecasts with the freeze risk model. In this system, daily accumulation of thermal time since last fall leads to the dormancy state (depth) for today. The regional minimum temperature forecast for tomorrow by the Korea Meteorological Administration is converted to the site specific forecast at a 30m resolution. These data are input to the freeze risk model and the percent damage probability is calculated for each grid cell and mapped for the entire county. Similar approaches may be used to develop freeze warning systems for other deciduous fruit trees.

Purpose: This study was conducted to estimate the changes of corrected diopter and corrected visual acuity with the change in vertex distance. Also we aimed to provide basic data for refraction test. Methods: Using the trial lens, we measured the corrected diopter and corrected visual acuity after performing binocular balance test. We measured the changes of corrected diopter and corrected visual acuity in change of vertex distance. We analyzed statistical significance and relations between vertex distance and corrected diopter and corrected visual acuity. Results: There was no difference in corrected diopter with the change of vertex distance within -1.00D, but the corrected diopter increased with it over - 1.25D. In particular, the change of diopter was largest when the vertex distance increased 15 mm. At over 11.00D, there was large changes of diopter with the changes of vertex distance at 5 mm, 10 mm and 15 mm. On correlation analysis between the vertex distance and the corrected diopter, there was strong correlation (r=0.999 at 5 mm increase of vertex distance, r=0.982 at 10 mm increase and r=0.957 at 15 mm increase) and also there was significant (p<0.01). At the change of visual acuity in increased of vertex distance, the range of a decrease in visual acuity was large when the changes of vertex distance was largest. On correlation analysis between the vertex distance and the corrected visual acuity, there was strong correlation (r=0.969 at 5 mm increase of vertex distance, r=0.985 at 10 mm increase and r=0.994 at 15 mm increase) and also there was significant (p<0.01). Conclusions: The vertex distance was very important at the refraction test and at wearing spectacle. On correlation analysis between the vertex distance and the corrected diopter, and the corrected visual acuity, there was strong correlation and statistically significant. Therefore, the vertex distance should be kept at the refraction using trial lens, and the best fitting was made not to slipping forward, and so we suggested regular refitting of spectacle and the managing method of spectacle were educated to the spectacle wearers.

The purpose of this study is to analyze the nutrient intakes and growth development of rural middle school students provided with and without the national school lunch program(NSLP). The subjects consisted of 340 rural middle school students provided with(n=177) and without(n=163) NSLP. Anthropometric measurements were taken for body weight, height, triceps skinfold thickness and percentage of body fat, and nutrient intakes were assessed by food record method. The results of this study were summarized as follows: There was no significant difference in the height, body weight girls provided with (155.8cm 47.2kg) and without (156.0cm, 49.7kg) NSLP. Total energy intakes of boys were 2123kca1 in with NSLP and 1857kca1 in without NSLP. Total energy intakes of girls were 1913kca1 in with NSLP and 1814kca1 in without NSLP. Total daily energy was provided in the ratio of 19.1%, 39.8%, 32.4% and 8.7% by breakfast, lunch, dinner and snacks in the with NSLP and 17.5%, 32.0%, 34.8% and 15.7% in without NSLP, respectively. Phosphorus, vitamin A, vitamin E, ascorbic acid, thiamin, riboflavin, niacin intakes were above the RDA in with NSLP. In without NSLP, phosphorus, vitamin E, thiamin intakes were above the RDA. however, calcium. iron, vitamin A, vitamin B$_{6}$ were less than the RDA. The study showed that total daily energy and nutrient intakes were significantly higher in students provided with than without school-lunch. Thus, the school-lunch program is recommended and necessary to improve the nutritional status of middle school students.

Effects of dietary fatty acids and vitamin E on antioxidant system were studied in rat liver and serum. Sources of dietary fat (10 wt%) were safflower oil (SO) poor in $\omega$3 fatty acid and mixed oil (MO) with computer-adjusted fatty acid ratios (AA/DHA=1.4, $\omega$6/$\omega$3=6.3, P/M/S=1.0/l.5/1) with (ME) and without (MO) vitamin E (500 mg/kg diet). Rats were fed the three kinds of diet from 3~4 wks prior to the conception. At the age of 3 and 9 wks of the second generation rat, antioxidant vitamins and glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) activities were measured in the liver and serum. The concentrations of $\beta$-carotene were lower in ME than in MO and SO in the liver at the age of 3 wks. It seemed that vitamin E has an inhibitory action on the uptake of $\beta$-carotene or acts as a preferred antioxidant to $\beta$-carotene. The concentrations of lycopene were lower in SO than in MO in the liver at the age of 3 wks. The concentrations of cryptoxanthin showed no significant changes within groups. The activities of GSH-Px tended to increase in ME compared to MO and the ratios of SOD/GSH-Px tended to decrease in ME compared to MO in the liver at the age of 3 weeks. The activities of antioxidant enzyme at the age of 3 weeks and 9 weeks were similar. This suggested that the activity level of antioxidant enzymes reached to the adult level at the age of 3 weeks which is the end point of lactation period.
