There are many opportunistic events that accidentally happen in Rin Taro's animations. However, audiences usually enjoy them in which dramatic catastrophic scenes inflict destruction on a city. Every acquaintance that a hero meets helps him to complete his wish in . Rin's animations describe the hero as a person that every acquaintance is eager to help. This means that the fulfillment of hero's wish depends on sympathy of the other persons toward the hero. Thus, the hero is psychologically dependent on the others. However, Rin Taro gradually became to describe destructive aspects of psychological dependence. A female character in 'X' has a symbiotic relationship with a computer that has a human-like jealousy. At last, it kills her from its jealousy. Rin Taro had shifted from helpful psychological dependence to destructive one in his animations. Therefore, Rin Taro described Japanese mental state as psychological dependence in his animations in accordance with the present state in Japan.

In the soft drink industry, especially small and medium enterprises in Japan, there is a possibility of conversion from a labor-intensive industry to a capital-intensive. The demand for soft drinks may not be satisfied in the summer because the supply is too low to meet the demand. To address this situation, this paper proposes optimal investment that integrates demand uncertainty, based on real options approach (ROA) and seasonal autoregressive integrated moving average. Two alternative options are compared and evaluated. One is the Bermudan option: to employ additional workers to elevate efficiency in summer and laying off in winter, this attitude is repeated each year. The other is the American option: to replace equipment to increase machine ability throughout the year. Results in ROA show that the highest improvement is gained if the two options are in a symbiotic relationship. Soft drink producers should search for replacing equipment, using the employees repeatedly. A temporary decision is not equal to an infinite decision.

Fungi of the genus Tuber are ectomycorrhizal fungi that form a symbiotic relationship mainly with oak and hazel trees. Tuber spp. exhibit a highly selective host plant preference; thus, for cultivation purposes it is important to select an appropriate host plant for successful mycorrhization. In addition, as mycorrhizal characteristics differ according to Tuber spp., it is necessary to understand the differences in mycorrhizae according to the fungal species. Tuber huidongense and Tuber himalayense were recently discovered in Korea; therefore, we used spore suspensions from these two species to inoculate two species of oak trees, Quercus acutissima and Quercus dentata, to compare colonization rates and morphologies of the mycorrhizae. The colonization rates demonstrated that the different Tuber spp. favored different host plant species. In addition, unique morphological and anatomical characteristics were observed for T. huidongense and T. himalayense depending on the host species. These findings can lead to new economically important agricultural activities related to truffle cultivation in Korea.

Probiotics provide a symbiotic relationship and beneficial effects by balancing the human intestinal microbiota. The relationships between microbiota changes and various diseases may predict health abnormalities and diseases. Treatment with vitamins and probiotics is one therapeutic approach. To evaluate the effect of probiotics on vitamin absorption, we chose Lactobacillus rhamnosus CBT-LR5 treatment, which has resistance to vitamin C-inducible toxicity, with vitamins in high-fat diet (HFD)-induced obesity models. CBT-LR5 affected the absorption of micronutrients, such as ionic minerals and water-soluble vitamins. An increase in vitamin C absorption by CBT-LR5 enhanced the antioxidant response in HFD-induced obesity models. Increased vitamin B absorption by CBT-LR5 regulated lipid metabolism in HFD-induced obesity models. These favorable effects of CBT-LR5 on the absorption of vitamins should be investigated as candidate therapeutic target treatments for metabolic diseases.

The purpose of this study is to analyze the regionality of RCR Arquitectes's architectural characteristics and to figure out how these characteristics were applied to each project. The reason why they become world-class architects, who recently awarded Pritzker Architecture Prize, is because they deal with universality as their most previous inspiration which is harmonized with their own experience of hometown, Olot. They pursue "Equilibrium" is their fundamental aspect which is inspired by their experiences in Olot. The concept "Equilibrium" is classified into three main points. First, the close relationship between the landscape and architecture is priority in this concept, which is the potential of the place through architecture to form a new landscape and to pursue a balance with nature. In order to keep the relationship closer, they captured the intuitive idea through the watercolor sketch in the beginning of the project. And they also promoted the involvement of surrounding nature through horizontality, frame and void, etc. Secondly, they used cor-ten steel as the main material for most projects, and the symbiotic relationship with nature that allow people to have a different sensory experience. And the last feature is that their buildings are easily applied to different usage through users intend and behave so their buildings have transformed with various values. It is because they design buildings with strategy to harmonize between landscape and environment so they have various expansion as buildings or objects. The present era of globalization, architecture with regional identity plays an important role in conveying the values of each region. The purpose of this study is to investigate about RCR Arquitectes, who informed about the Olot and Spain's regionality, and to consider the development of architecture that implies our country's identity.

Purpose: The major objective of this study is to develop a model for the impact of franchisors' Gapjil (verbal·nonverbal Gapjil, abusing bargaining position, refusing transaction, false or exaggerated information, restrictive practices, unfair damage compensation) on franchisee's recontract intention. We also examine the mediating role of economic satisfaction and social satisfaction in the relationship between franchisors' Gapjil and franchisee's contract intention. Research design, data, and methodology: Data were collected from franchisee owners located nationwide in Korea. Out of 256 questionaires distributed, a total of 256 questionnaires were returned. After excluding 10 invalid respondent questionnaires, we coded and analyzed 246 valid questionnaires (effective response rate of 96.09%) using frequency, confirmatory factor analysis, correlations analysis, and structural equation modeling with SPSS 22.O and SmartPLS 3.0. Results: The findings of this study are summarized as follows: First, among the Gapjil of the franchisors, restrictive practices and unfair damage compensation had negative effects on economic and social satisfaction, but verbal and nonverbal Gapjil for economic and social satisfaction was not significant. Second, abusing bargaining positions and false or exaggerated information had negative effects on social satisfaction, but for economic satisfaction, found to be insignificant. Third, economic and social satisfaction had positive effects on the franchisee's recontract intention to the franchisor. Conclusion: The following implications of this study are as follows. First, the construct of Gapjil that occurs between the franchisors and the franchisees was first presented, and the franchisors' Gapjil is divided into interpersonal Gapjil and structural Gapjil. Second, the Gapjil of the franchisors can be an important predictor variable in maintaining and developing a long-term relationship between the franchisors and the franchisees. Third, solving conflict due to the Gapjil problem between franchisors and franchisees can be an important factor for franchisors and franchisees to co-survive and thrive in Korean franchise system. Fourth, this study suggest that managing the Gapjil of the franchisors was a important antecedent factor in maintaining long-term relationship between the franchisors and the franchisees. Therefore, this study will help franchisors formulate effective symbiotic marketing strategies to satisfy relationships with franchisees and consequently enhance long-term orientation.

Tall fescue (Schedonorus phoenix Scop.) is resistant to abiotic and biotic stresses through a symbiotic relationship with Neotyphodium coenophialum. However, this endophyte has been considered detrimental since it produces toxic alkaloids to animals. It is vital to understand mutuality between these two to maximize positive impact of the endophyte on agri-ecosystem. Little research has been conducted on endophyte transmission mechanism in planta. To provide basic information related to endophyte transmission, an experiment was conducted to examine the effect of endophyte genotype and water stress on endophyte transmission by imposing soil moisture deficits at different stages of panicle development. There was water stress effect on endophyte frequency but not on concentration, whereas endophyte genotype significantly influenced endophyte concentration in pseudostem of tall fescue at boot stage. Reproductive tillers showed greater endophyte frequency and concentration. Endophyte frequency in florets or seeds depended on position within panicle. There was no drought effect on endophyte concentration, but showed the effect of endophyte genotype on endophyte concentration in florets and seeds. Overall endophyte concentration in seeds was higher. From this study, we may conclude that although water stress reduced endophyte frequency in vegetative tiller, water stress does not have effect on endophyte transmission, suggesting that drought is not an important factor controlling the endophyte transmission from plant to seed. Endophyte genotype and seed position in a panicle affected endophyte transmission, indicating that these two factors are involved in endophyte transmission and may determine seed transmission of endophyte in tall fescue.

Twelve plant species were collected from the east coast of Korea to identify culturable endophytes present in their roots. The fungal internal transcribe spacer (ITS) region (ITS1-5.8SrRNA-ITS2) was used as a DNA barcode for identification of fungi. A total of 194 fungal strains were identified and categorized into 31 genera. The genus Penicillium accounted for the largest number of strains, followed by the genus Aspergillus. Furthermore, using 5 statistical methods, the diversity indices of the fungi were calculated at the genus level. After comprehensive evaluation, the endophytic fungal group from Phragmites australis ranked highest in diversity analyses. Several strains responsible for plant growth and survival (Penicillium citrinum, P. funiculosum, P. janthinellum, P. restrictum, and P. simplicissimum), were also identified. This study provides basic data on the sheds light on the symbiotic relationship between coastal plants and fungi.

The purpose of this study is to reveal the kind of traditional perspectives we can use from the past to create a sustainable society for the future and to contribute to the growing interest in, and concern for, environmentally-sound designs. Such perspectives include ways to sustain naturalistic aesthetic views, elements of architectural design, and ideas for traditional lifestyles. Architecture that used these methods would contribute to a more ecologically sensitive view of man's place within the natural environment. This research was conducted by way of literature reviews; the objects of study were physically extant traditional housing, the composition of the traditional village, and traditional lifestyles. The results of this study indicate that the ecological characteristics of traditional Korean homes originated from a holistic conception of society and nature; this holistic conception has been found lacking in our more modern, western influenced homes. In the past, in order to leave an unpolluted or even healthier natural environment to descendents, it was essential to apply ecological principles. Villages harmonized with nature and houses were designed to utilize sunlight and wind. Their natural construction promoted consciousness of human beings and their symbiotic relationship with nature.
