Today's companies build strong brand assets which, through the expansion of other business areas, promote efficient corporate management. Many companies manage brand assets among through a multitude of brand groups using brand portfolios rather than the single brand strategy. Such brand group influence can be related not only to brand group expansion, but also to parent company brands and product brand groups. The purpose of this study was to identify the effects of parent corporate brand associations on brand portfolio evaluation. The results of the present study is as follows: positive parent corporate brand image was revealed to play a positive role in brand portfolio evaluation. Parent corporate brand image provided endorsement for their product brands, and this can reduce consumer's decision cost on brand portfolio evaluations. This study focused on two types of brand relationship strategy : brand expansion strategy and individual brand strategy. With individual brand strategy, cases where parent company brands provided endorsement and cases to the contrary were studied separately. In cases where well-managed parent corporate brand image were able to provide endorsement in the case of individual brand strategy like that of brand expansion strategy.

Samuel Eliot Morison (1887-1976) was one of the pre-eminent historians of his generation. He was not only a famous historian at that time, but also was promoted to the rank of Admiral in U.S. Navy Reserve. Fifteen volume History of United States Naval Operations in World War II was published between 1947 and 1962, was not only a comprehensive report on the Navy's projection of power over two oceans, but a classic of historical literature that stands as the definitive treatment of it subject. Although he was fifty-five when war come to America in December 1941. Samuel Eliot Morison was determined to play a role. A professor at Harvard at the time, he joined volunteering for duty in the Navy. An experienced sailor, Professor Morison had earlier sailed that same routes taken by Christopher Columbus while researching his biography, Admiral of the Ocean Sea, which appeared in January 1942 th much acclaim and later got a Pulitzer Prize. Thus Morison plunged into the war, crossing the Atlantic aboard a destroyer. He assumed himself as "Parkman on the sea", tried to follow Parkman's historiographic method, not only participatory history but also literary style. And during writing History of United States Naval Operations in World War II, He emphasized two principles, publicity and objectivity. In terms of publicity, he always worried about who read history and why. In his pamphlet, "History as a Literary Art", he asserted it is useless if readers do not read a history which historians wrote. So he thought historians have forgotten that there is an art of writing of history. Therefore, he built his narratives around brightly rendered visuals and used the present tense to describe actions he witnessed firsthand, he wrote of the U.S. combat in very vividly. But strongly driven by publicity, he sometimes lost his balance in writing the naval history. For instance, the naval history became the focus of criticism for its prejudiced comments about the commanders. Also some reviewers asserted he did not secure the objectivity on writing the naval history. Although he sometimes deliberately torpedoed the objectivity of his work for strengthening publicity, by writing an extensive U.S. naval history, he introduced maritime history and naval history to the public widely. Until in early twentieth century, U.S. historians usually had been focusing their effort to the traditional areas, for example politic, economy, and etc. His intensive effort on the operations of U.S. Navy in World War II aroused a public interest in maritime and naval history. In conclusion, through using literary style and realistic narratives, historian Morison wrote a naval history for all the people which could appealed to the public.

High school credit system refers to a system in which a student selects the desired content according to his/her subject and completes accumulated credits to reach graduation when a certain standard is reached. The purpose of this study is to identify the advantages and disadvantages to the technology and home economics education after the introduction of the high school credit system by analyzing the status of high school elective subjects in technology and home economics areas, and the perceptions and needs of teachers and experts as the introduction of the high school credit system approaches. A survey was conducted to all professors in the Department of Home Economics Education or Technology Education, along with a national sample of the secondary school teachers of Home Economics and Technology, and responses of 282 teachers and 36 experts were analyzed. Results are as follows: First, in general high schools, the formation and operation of elective courses in technical and home economics were very insufficient. Second, there was a large number of requests for the expansion of elective courses in technology and home economics among the high school teachers. Third, in order to take advantage of the high school credit system, it was recognized that elective courses in technology and home economics should be established not only in consideration of secondary school education, but in relation to their connections with majors in universities. Improving the structure of electives in this direction is expected to play a positive role in allowing elective courses in technology and home economics to contribute to ensuring students' free choice.

This study aims to suggest a way for temple food to take a differentiated position in the foodservice industry along with providing useful data for efficient management of temple food. To do this, it examines what influence the characteristics of temple food has on satisfaction with the food and verifies how the types of religion adjust the relationships between the characteristics and the satisfaction. The consumers who frequent temple food restaurants in Seoul and Gyeonggi areas were selected as the sample for this study, and a survey was conducted to those over the age of 20 via self-administered questionnaire from May 1st to June 30th, 2012. A total of 500 copies were distributed and 476 copies were selected as suitable from 488 copies collected for reliability and factor analyses using SPSS 18.0. The proposed research hypotheses were verified with a regression analysis and a multiple regression analysis. The results of this study are as follows. First, the characteristics of temple food have a positive influence on satisfaction with the food. Their subordinate factors such as situation, function, and consistency have positive(+) effects on the satisfaction. Next, it shows that religion does not play a regulatory role in the relationships between the characteristics of temple food and satisfaction with the food.

The author argues that the current Government Information System for river water quality appears to be non-user friendly due to lack of the cartographic representation for the field monitoring data. Acknowledging these constraints, an operational, user-friendly information system has been developed by combining Internet technology with GIS. A digital map for water quality has been generated by overlaying monitoring data on existing cartographic data such as road, topography and administrative boundary etc. A user interface was designed to address the need to querry the large spatial databases by non-GIS and non-environmental experts. The system has been checked experimentally and enabled the users to querry data required simply. And detailed visual maps for water quality can be generated over large areas quickly and easily. A visual mapping system for water quality was developed by reframing the monitoring data as graphic symbols and it was ideally suited to exploring area-wide water quality at a user-friendly manner due to extensibility and scalability along the various survey points. This system based on Web GIS could be accessed anywhere if internet is available. It would play a crucial role in improving the quality of public information service if it is operationally introduced into the Government since the highly user-friendly interface provides a completely new means for disseminating information far water pollution in a visual and interactive manner to the general public.

Synthetic bone graft materials have been used for the regeneration of periodontal tissue lost due to periodontal disease, but the limitations of these materials had prompted the use of composite grafts. Among those, a composite graft of calcium carbonate(CC) and calcium sulfate(CS) is one of those materials that has not been studied extensively. CC, which is extracted from a natural coral, is known to possess osteoconductive property. SC can play an adjunctive role in the regeneration of bone tissue, and has shown good resorbability and biocompatibility. This study was conducted in order to investigate the effects of CC and CS composite graft to the regeneration of bone in the intrabony defects of dogs. 3-wall intrabony defects ub size of $4mm{\times}4mm{\times}4mm$ were created in the alveolar bone in the premolar areas. Then those defects that were treated with root planning only were designated as control, while the experimental group 1 and 2 each received the CC and CS composite grafts in the ratio of 8 : 2 and 5 : 5 the animals were sacrificed after 8weeks and the specimens were histologically analyzed. The results were as follows ; 1. No inflammation or foreign body reaction were observed in all subjects. CS has not been seen due to complete resorption, and resorption pattern of CC was observed. 2. Significant differences(p<0.05) in new cementum formation were observed between control($1.42{\pm}0.64mm$) and experimental groups(group 1 ; $2.53{\pm}0.94mm$, group 2 ; $2.23{\pm}0.96mm$) but the difference between the two experimental groups was not significant. 3. Significant differences(p<0.01) in new bone formation were observed between control($0.59{\pm}0.55mm$) and experimental groups(group 1 ; $2.27{\pm}0.61mm$, group 2 ; $2.05{\pm}0.56mm$) but the difference between the two experimental groups was not significant. 4. The extent of apical epithelial migration has shown no significant difference between control($1.18{\pm}1.24mm$) and experimental groups(group 1 ; $0.51{\pm}0.54mm$, group 2 ; $0.73{\pm}0.70mm$). 5. The extent of bone formation was generally limited to the extent of cementum formation for all groups, and significant correlation was found in the amount of bone formation and cementum formation in experimental group 1.(Co.=0.86, p<0.01) These results suggest that the composite graft of CC and CS is biocomplatible and effective in the new bone and new cementum formations. In the case of 3-wall intrabony defects of dogs, the composite ratio of 8 : 2 and 5 : 5 had shown no significant differences in the healing.

To avoid drought stress under rainfed upland conditions, it is important for rice to efficiently utilize water at shallow soil layers supplied by rainfall, and access to water retained in deer soil layers. The root developmental characteristics of rice, which play important role in the adaptability to drought conditions, vary depending on the variety. Moreover, water availability for plant differs depending on the soil types that have different physical properties such as water holding capacity, permeability, capillary force, penetration resistance, etc. In this study, we evaluated growth and yield responses of rice varieties to various soil water deficit conditions under three different soil types. The experiment was conducted in a plastic greenhouse at the Kenya Agricultural and Livestock Research Organization-Mwea from October 2016 to January 2017. Two upland varieties (NERICA 1 and 4) and one lowland variety (Komboka) were grown in handmade PVC pots (15.2 cm diameter and 85.0 cm height) filled with three different types of soil collected from major rice-growing areas of the country, namely black cotton (BC), red clay (RC), and sandy clay (SC). Three watering methods, 1) supplying water only from the soil surface (W1), 2) supplying water only from the bottom of the pots (W2), and 3) supplying water both from the soil surface and the bottom of pots (W3), were imposed from 40 days after sowing to maturity. Soil water content (SWC) at 20, 40, and 60 cm depths was measured regularly. At the harvesting stage, aboveground and root samples were collected to determine total dry weight (TDW), grain yield, and root length at 0-20, 20-40, 40-60, and 60-80 cm soil layers. Irrespective of the watering methods, the greatest root development was obtained in RC, while that in BC was less than other two soils. In BC, the degree of yield reduction under W1 was less than that in RC and SC, which could be attributed to the higher water holding capacity of BC. In RC, the growth and yield reduction observed in all varieties under W1 was attributed to the severe drought stress. On the other hand, under W2, SWC at the shallow soil depth in RC was maintained because of its higher capillary force compared with BC and SC. As the result, growths and yields in RC were not suppressed under W2. In SC, deep root development was not promoted by W2 irrespective of the varieties, which resulted in significant yield losses. Under W1, the rice growth and yield in SC was decreased although shallow root development was enhanced, and the stomatal conductance was maintained higher than RC. It was suspected that W1 caused nutrients leaching in SC because of its higher permeability. Under rainfed conditions, growth and yield of rice can be strongly affected by soil types because dynamics of soil water conditions change according to soil physical properties.

Cancer cells exhibit increased demand for glutamine-derived carbons to support anabolic processes. Indeed, the spectrum of glutamine-dependent tumors and the mechanisms through which glutamine supports cancer metabolism remain areas of active investigation. In the present study, we investigated the effects of glutamine deprivation on the correlation between tightening of tight junctions (TJs) and anti-invasive activity in human prostate carcinoma LnCap cells. Glutamine deprivation markedly inhibited cell motility and invasiveness in a time-dependent manner. The anti-invasive activity of glutamine deprivation was associated with an increased tightness of the TJ, which was demonstrated by an increase in transepithelial electrical resistance (TER). The activities of matrix metalloproteinase (MMP)-2 and MMP-9 were inhibited in a time-dependent fashion by glutamine deprivation, which was correlated with a decrease in expression of their mRNA and proteins and up-regulation of tissue inhibitors of metalloproteinases (TIMPs) expression. Furthermore, glutamine deprivation repressed the levels of the claudin family members, which are major components of TJs that play a key role in the control and selectivity of paracellular transport. Moreover, the levels of E-cadherin, a type I transmembrane glycoprotein, and snail, an epithelial to mesenchymal transition regulator and zinc finger transcription factor, were markedly modulated by glutamine deprivation. Taken together, these findings suggest that TJs and MMPs are critical targets of glutamine deprivation-induced anti-invasion in human prostate carcinoma LnCap cells.

As three sides of Korea are surrounded by the sea and it is geographically located at an intersect point for continental and maritime climate, the climate crisis and global warming factors that lead to large-scale natural disasters such as typhoons, floods, and tsunami as well as disasters and damage to humans are increasing due to rapid urbanization and industrialization. Therefore, this study measured the ability of people to cope with disaster in students studying emergency rescue who will play a central role in safety and casualty control in disaster areas in order to figure out the factors that will influence their overall ability. As a result, the following things were discovered: Those who had the experience of listening to information on how to cope in a disaster scored significantly higher in disaster coping scores than those who did not. In comparison with subjects who responded that they were not satisfied with their emergency rescue training at school, those who responded that they were satisfied with their education scored significantly higher in their disaster coping scores. In comparison with subjects who responded negatively to the questions on experience in emergency rescue training as an extracurricular program, those who responded affirmatively to the questions were evaluated as significantly higher in their disaster coping scores. This study suggests that specific strategies can be taken and are needed to improve the ability to cope with disasters in students who are studying emergency rescue.

Objective: Minerals are one of the important nutrients for supporting the growth of sheep grazing in the highland, northwest of China. The experiment was conducted to investigate the relationship of both macro and micro minerals in sheep grazing in the highlands of six districts located in the Qilian Mountain of China. Methods: Samples of herbage (n = 240) and soil (n = 240) were collected at random in a "W" shape across the area designated for harvesting from 24 farms, where the sheep commonly graze in October (winter) for mineral analyses. In addition, serum samples were taken via jugular vein from 20 sheep per farm from 24 farms (n = 480 samples in total) for serum minerals analyses. Mean values of macro and micro minerals were statistically compared among districts and the correlations among soil-plant-animal were statistically analyzed and correlations were regressed, as well. Results: The results revealed that there were variations for both macro and micro minerals among districts. Statistical analysis of the correlation coefficients between herbage and sheep were significantly different for most of the minerals but not for P, Cu, and Se. Many correlation regression coefficients were found significantly different among minerals of herbage, soil, and sheep serum especially those of K, Na, Fe, Mn, and Zn (between herbage and sheep serum), and Fe and Mn (between herbage and soil), Na, Fe, Mn, and Zn (between soil and sheep serum), respectively. The regression coefficient equations derived under this experiment for prediction of Ca (R² = 0.618), K (R² = 0.803), Mg (R² = 0.767), Na (R² = 0.670), Fe (R² = 0.865),Zn (R² = 0.950), Mn (R² = 0.936), and Se (R² = 0.630), resulted in significant R² values. Conclusion: It is inferred that the winter herbage minerals in all the districts were below the recommended levels for macro minerals which indicated there would be some mineral deficiencies in sheep grazing the herbage in these regions. Supplemental minerals may therefore play an important role in balancing the minerals available from the herbage in winter and would lead to increased productivity in sheep on the highland areas of China. These findings could be potentially applied to the other regions for improving the livestock productivity.
