Recently, the scope of user interface is increasing the relative importance in software development dramatically. As a result, there are various relative technologies like as SWING, MFC, Web 2.0, and etc. However, most current software developments are progressed in separate development process with user interface part and business part respectively. This causes the problems, like as a difficulty in the integration process, an development period's delay, and a poor reusability for the constructed models. That is, the extendability and reusability of the created models is being decreased because UI modeling is not systematic and hierarchical, and the consistent integration technique between UI modeling and business modeling does not supported. To solve these problems, this paper proposes an unified and systematic UI modeling process based on UML, using the hierarchical metamodel according to the abstraction levels of development phase. We suggest an UI metamodel, which contains a hierarchy by layering the modeling elements in PIM and PSM based on maturity degree of the development. An hierarchical modeling process combined UI modeling and business modeling is built by applying the UI and business metamodel in terms of three modeling phases(concept/specification/concrete). The effectiveness of the modeling process is shown by applying the proposed process into an Internet Shopping Mall System. Through the exploratory results, the hierarchical UI metamodel and process can produce systematic and layered UI models. This can improve the quality and reusability of models.
The main purpose of this study is to provide an objective evaluation standard for the assessment of marine spatial characteristics via Ulsan floating offshore wind power project using HEA.. Various levels of damage occur in the waters (5,017.6) near the floating offshore wind power terminals in Ulsan, including commercial damage, ecological destruction and reduction in quality of life due to seascape damage. Alternative restoration projects for calculating the economic value of damage were selected including artificial reef projects and estimates based on HEA. For basic households with a 4.5% social discount rate and a 100% maturity index over four years, the damage was approximately 457 hundred million won. The HEA in this study resolves the possible irrationality in the evaluation of marine spatial characteristics, since the value is calculated based on objective and clear DATA. Therefore, the study results are intended to facilitate conflict resolution between stakeholders in the future during the implementation of the marine spatial plan.
The present study was conducted to evaluate agronomic characters of the soybean germplasm which was collected from the sites covering southern parts of Korean peninsula. The total collections of 2748 native soybean varieties were grouped by eight levels of seed weight and the correlation between the seed weight and the other agronomic traits were determined. Seed weight was ranged from 7. 3g to 48. 4g with a great variation and averaged 23. 5g. Seed size of the many local lines were relatively large than that of foreign varieties. Frequency distribution of the germplasm for seed weight were 2.2% in Group 1 (below 10.0g), 14.7% in Group 2 (10.1-15.0g), 11.7% in Group 3 (15.1-20.0g), 26.2% in Group 4 (20.1-25.0g), 30.2% in Group 5 (25.1-30.0g). 10.6% in Group 6 (30.1-35.0g), 3.3% in Group 7 (35.1-40.0g) and 1.1% in Group 8 (over 40.0g). There was positive correlationship between seed weight and maturity or fruiting period, while there was negative correlationship between the seed weight and the other traits such as days to flowering, plant height, and number of nodes and pods. While 100 seed weight of 464 lines (16.9% of total lines) were below 15g, and those are adequate for the bean sprouts. The fruiting period of large seeded lines was longer, however the number of pods per plant of those were less lines than that of small seeded lines.

The aim of this study was to investigate the effects of slow maxillary expansion (SME) on the dentoalveolar, skeletal, upper airway, and maxillary sinus using cone-beam computed tomography (CBCT). Twenty-three orthodontic patients (mean age 8.93 ± 1.61 years) who were treated with maxillary expansion using banded hyrax in the Department of Pediatric Dentistry at Jeonbuk National University Dental Hospital were included. According to the expansion speed applied, they were divided into two groups: SME (12 subjects, mean age 8.92 ± 1.45 years) and rapid maxillary expansion (RME, 11 subjects, mean age 8.94 ± 1.84 years). CBCT were obtained before (T0) and after (T1) the treatment and were analyzed with InVivo5 software (Anatomage, San Jose, CA, USA). Descriptive statistics showed no significant differences between the two groups in age, sex, or skeletal maturity. There were significant increases in maxillary width at the dentoalveolar and skeletal levels for both groups. Upper airway volume revealed a significant increase of 38.59% in the SME group and 28.72% in the RME group. However, there was no significant difference between SME group and RME group in all measurements. This study suggested the efficacy of SME in growing patients. SME was effective in increasing not only dentoalveolar and skeletal measurements but also airway volume. Therefore, pediatric dentists should select an appropriate expansion method considering the physiological aspects of periodontal tissues and discomfort in growing children.

The pot trial was carried out to investigate the influence of soil temperature on the growth and dry matter accumulation in sorghum cv. Pioneer 931 and corn cv. Suweon 19 during their growing season in 1985. Soil temperature maintained with low ($22.3^{\circ}C$), natural($25.9^{\circ}C$) and high temperature($30.5^{\circ}C$) over 24 hour. The results are summarized as follows; 1. Growth of sorghum plants was associated with increasing of soil temperature, while that of corn was reduced under high temperature($30.5^{\circ}C$). The highest plant height of corn was found at natural temperature($25.9^{\circ}C$). Sorghum had higher growth rate than corn plants in all temperature levels. 2. Assimirable leaf areas of the plants were greately increased under high temperature both in sorghum and corn. Sorghum plants maintained almost same levels of leaf area during maturity stage, but those of corn were markedly decreased after mild stage. 3. The highest rates of photosynthesis were found at nature' soil temperature ($25.9^{\circ}C$) both in sorghum($1.619mg/s/m^2$) and corn plants($1.084mg/s/m^2$). Under high temperature($30.5^{\circ}C$) the photosynthesis rates of the plants were decreased to about 1.553 mg and 0.404 mg for sorghum and corn, respectively. Low temperature ($22.3^{\circ}C$) produced only a value of 0.775 mg for sorghum and 0.048 mg for corn. 4. Seasonal dry matter accumulation of sorghum increased in the order of high>natural>low soil temperature, but that of corn increased in the order of natural>high>low soil temperature, respectively.

This study was carried out investigate the effects of the period of dietary supplementation and the level of fermented mineral feed on daily body weight gain and carcass characteristics of Hanwoo steer. The dietary treatments were compared during two supplementation periods (T1:Feeding Hanwoo steers from 18 months to 25 months, T2: feeding Hanwoo steers from 7 months to 25 months), and the diets tested were of four types (0%: normal concentrate as a basal diet, 1%: 1% addition of fermented mineral feed, 2%: 2% addition of fermented mineral feed, and 3%: 3% addition of fermented mineral feed). A Total of 35 Hanwoo steers were allocated into 7 feeding groups. The daily gain of the 0% fermented mineral feed group was lower (0.64 kg) than that of the other groups (1%: 1.08 kg, 2%: 0.90 kg, 3% treatment: 0.75 kg) for the T1 period, and for the T2 period the order was 1% (0.98 kg) > 0% (0.75 kg) > 1% (0.89 kg). The amount of back fat in decreasing order was as follows: 0% (12.0) > 1% (10.8) > 2% (10.2) > 3% fermented mineral feed (7.8 mm) for the T1 period, and for the T2 period the order was C (16 mm) > T1 (13.8 mm) > T3 treatment (12.6 mm). Eye muscle area increased with increased fermented mineral feed levels. The marbling score of the T1 groups was highest with 3% fermented mineral feed (4.2), and of the T2 groups, the highest score was seen with 1% fermented mineral feed (5.6). Meat color and meat maturity were not different among all groups. The grade of meat quantity and meat quality of both the T1 and T2 groups were highest with the addition of 3% fermented mineral feed. The daily income ranged from 2,062 won to 5,265 won in the T1 groups, which were ordered as follows: 1% > 2% > 3% > 0% fermented mineral feed, and of the T2 groups, the 1% group was highest at 6,098 Won, while the 3% group was lowest at 4,590 Won.
Fruit ripening is a genetically programmed process involving a number of biochemical and physiological processes assisted by variations in gene expression and enzyme activities. This process generally affects the phytochemical profile and the bioactive principles in fruits and vegetables. To appraise the variation in bioactive principles of fruits from Rosa rugosa during its ripening process, we analyzed the changes in antioxidant and anti-elastase activities and polyphenolic compounds during the four ripening stages of fruits. Overall, an extract of unripe fruits contained the highest levels of total phenolic and flavonoid contents, radical scavenging activity, reducing power, oxygen radical antioxidant capacity, and elastase inhibitory activity, compared with the extracts of fruits at other stages of ripening. Additionally, we found that the reduction of flavonoid content occurs because of decreased transcriptional levels of genes involved in flavonoid biosynthesis pathway during the ripening process. Based on HPLC analysis, we found that the extract of unripe fruits contained the highest amount of myricetin, caffeic acid, chlorogenic acid, syringic acid, and p-coumaric acid and suggested that the antioxidant and anti-elastase activities of the extract obtained from stage 1, should be mediated by the presence of these compounds. Additionally, we analyzed the interaction sites and patterns between these compounds and elastase using the structure-based molecular docking approach, and suggested that chlorogenic acid strongly interacted with elastase. Together, these findings suggest that the maturity of fruits has profound effects on the pharmaceutical value of R. rugosa.
An experiment with the tobacco plant was conducted in the pots. A sandy humic soil was used with 2 levels of pH, 3.5 and 5.8 with 2 kinds of anions, Cl as $NH_4Cl$ and $SO_4$ as $(NH_4)_2SO_4$, and with 4 levels of pF, 1.5, 2.0, 2.5, and 3.5. The pH-treatment created different N-forms; $NH_4$ at low pH(3.5) and $NO_3$ at high pH (5.8). The results are summarized as follows: 1. At low pH (3.5) with high concentration of $NH_4$ given as $NH_4Cl$, the high content of $NH_4$ and Cl in tobacco resulted in plants suffering from $NH_4$ and Cl toxicity as well as Mn toxicity. As a result of these toxicity, an extremly abnormal growth of tobacco was clearly appeared. In the tobacco grown at low pH with $NH_4$ given as $(NH_4)_2SO_4$, a large amount of the $NH_4$ uptake developed Mg and Ca deficiencies. $NH_4-N$, which had been applied to the soil of high pH (5.8), was almost completely transformed into $NO_3-N$ by nitrification and, on this low acidic soil, the plants were all healthy regardless of Cl or $SO_4$ added together with $NH_4-N$. However, dry matter production was higher and maturity faster when $SO_4$ was used as anion than when Cl was used. 2. High moisture content in soil, to some extent, is necessary for a good development and growth of the tobacco plant. Phosphate uptake seemed to be limited at higher moisture stress. The dry matter yield of tops and roots of tobacco were in the order of pF 1.8 > 2.1 > 2.6 > 3.6, respectively. 3. Data of chemical analysis and dry matter yields of tops and roots showed that the tobacco plant followed the normal (C-A) concept. In the normal growth of plants, the carboxylate content of tops was quite comparable to the estimated (C-A) values. If $NH_4$ content of plants remains in quite high quantities, it must be analysed and taken into consideration for the (C-A) calculation. Al is not transported toward tops in toxic amounts due to its high immobility, it mostly stay in or on the roots, probably due to precipitation as a aolt. When Al is present in high quantities, it has to be considered into the (C-A) calculation.
1. In order to obtain useful mutants such as early maturity, resistance to lodging, high protein and oil content, and capability of high yield, dormant seeds of two soybean varieties, Jang Dan Baik Mok and Clark, were treated with ${\gamma}$-ray, Ethyl Methane Sulfonate(EMS), Ethylene Imine(EI)and combinations of ${\gamma}$-ray and EMS or EI. 2. The germination rate and survival rate in a variety Jang Dan Baik Mok were significantly decreased with ${\gamma}$-ray treatment while it was not the same in the Clark variety. A significant decrease for seedling height measured at 14 and 21 days after sowing was found with the increase of ${\gamma}$-ray dose in both varieties. 3. Germination rates in both varieties were significantly decreased as EI concentration increases, particularly severe damage in germination was observed at 0.008 Mo. concentration. Germination rate damages were found with EMS concentration increases in the variety Jang Dan Baik Mok while no regular responses in seedling height were observed in the variety Clark. 4. Germination rate was significantly lowered with the combined treatment of EMS and ${\gamma}$-ray 24KR than that of EMS alone. In the treatments of ${\gamma}$-ray with three levels of EI concentration, the combined treatments except 24KR+EI 0.002 Mol. resulted in better germination than of EI alone. In both varieties, significant reduction in seedling height was observed in the combined treatments of ${\gamma}$-ray with various concentrations of EMS, whereas stimulation effect on seedling height was found with treatment of ${\gamma}$-ray EI +0.08Mol. 5. Germination rate, survival rate, and plant height as criteria of radio sensitivity, variety Jang Dan Baik Mok is moze sensitive to ${\gamma}$-ray, EMS, and EI than the variety Clark, and the varietal difference in responsibility to mutagen may be due to the genetic-constitution of the varieties.
This study was carried out to investigate the effect of electron beam irradiation and cooking temperature on physico-chemical characteristics and lipid oxidation of beef. A total of six beef carcasses ($280\∼300 kg$) that were quality grade $1^{+}$(marbling score No.7, meat color No.4, maturity No.1, texture No.1) was purchased at the commercial slaughter house. The carcasses were transported and washed using high pressure water, and pasteulized with $ 50\% $ ethyl alcohol in the laboratory. After the carcasses were deboned and trimmed, loin and round were taken out to make steak (1.5cm thickness) or ground beef respectively. Samples were wrap or vacuum packaged and irradiated with 0, 3, 4.5, 6 and 7.5 kGy using electron-beam accelerator at Samsung Heavy Industries Ltd. Co. (in Taejun). Irradiated samples were cooked with different methods(electronic pan and gas oven) and temperatures ($ 60^{\circ}C, 70^{\circ}C and 80^{\circ}C$) and used to measure fatty acid composition, TBARS, cholesterol oxide products and panel test scores. The content of saturated fatty acids increased by increasing heating temperature in oven boiling steak (OBS) and pan boiling steak (PBS), and there was no difference by electron-beam irradiation. Both irradiated and non-irradiated treatment were high as the heating temperature increased in TBARS by heating temperature in PBS (p < 0.05) and the amount of Malonaldehyde (MA), standard of fat deterioration, was increased in OBS (p < 0.05). Non-irradiated and 3, 6 kGy treatment produced about 2 fold amount of MA at $ 60^{\circ}C $ compared with $ 80^{\circ}C $. In comparison with PBS, OBS produced much amount of MA and a bit different from non-irradiated treatment but did not show no tendency. As irradiation levels and heating temperature increased, the amount of cholesterol oxides products was increased and also pan-heating method, direct heating method, significantly increased the degree of oxidation compared with oven-heating method, indirect heating method (p < 0.05).
