Purpose: This study started with interest in sport culture and is meaningful as an exploratory study to help with the basic understanding of sport culture research. Research design, data, and methodology: The approach of this study is the exploratory approach by literature reviews. This study carried out exploratory research on thinking about diversity of sports culture and the development process of sports culture by human history periods. Results: First, in thinking about cultural diversity, cultural absolutism and cultural relativism were identified. The characteristics of sports culture can identify universality, individuality and diffusion, and the attributes of sports culture included sharing, learning, accumulation, whole systematic relationship and change. Second, the characteristics of sports culture were identified by the approach of each historical era. The historical stages were divided into ancient civilizations, ancient Greece and Rome, middle ages and early modern period, and late modern period. Sports have historically been found to have a British-centered European origin or popularized in the United States. Conclusions: with the characteristics of modern sports culture, the globalization of sports culture, the prominence of sports industry and sports space marketing, and the symbiotic influence relationship of sports and mass media were examined and future directions were discussed.

We describe and illustrate two pontoniine shrimps, Cuapetes grandis and Periclimenes ornatus, for the first time in Korea. C. grandis was collected in an artifical reef of Dadae, Geojedo Island by SCUBA diving in 15-20 m depth. This species was found in an oyster within an artificial reef and appeared to be free-living. P. ornatus was collected from Seongsanpo, Jejudo Island by SCUBA diving in 10 m depth. This species had a symbiotic relationship with sea anemone. This record extends their previously known range from southern Japan to the Korean peninsula and the number of known pontoniine species in Korea to four.

Individualities of precious health mushroom called Zhenghonggu@ from respective protections scattered among all main mountains of Fujian China were collected and recognized locally, then compared with Russula griseocarnosa. Their internal transcribed spacer (ITS) region (ITS1, ITS2 and 5.8S rDNA) of the nuclear rDNA were amplified, AMOVA analyzed, nested clade analyzed and then compared with the ITS sequences of relative Russula species from other regions of China to confirm the taxonomic status of Zhenghonggu$^@$ and its population structure. Total 23 haplotypes from different protections of Fujian can be clustered into three clades similar to the three lineages of Dahongjun$^@$ from southeastern China reported by Li et al. The geographic distribution characteristic of these three phylogeny clades may be closely coupled with the vegetation regionalization and/or the differences of coenosium construction of Fagaceae that is the host of Russula griseocarnosa. The correlation of taxonomy, phylogeny and geographical distribution of Russula are discussed.

Fungi of the Metarhizium genus are a very versatile model for understanding pathogenicity in insects and their symbiotic relationship with plants. To establish a co-transformation system for the transformation of multiple M. robertsii genes using Agrobacterium tumefaciens, we evaluated whether the antibiotic nourseothricin has the same marker selection efficiency as phosphinothricin using separate vectors. Subsequently, in the two vectors containing the nourseothricin and phosphinothricin resistance cassettes were inserted eGFP and mCherry expression cassettes, respectively. These new vectors were then introduced independently into A. tumefaciens and used to transform M. robertsii either in independent events or in one single co-transformation event using an equimolar mixture of A. tumefaciens cultures. The number of transformants obtained by co-transformation was similar to that obtained by the individual transformation events. This method provides an additional strategy for the simultaneous insertion of multiple genes into M. robertsii.

There has been an ongoing symbiotic relationship between the history of the International Commission on Mathematical Instruction(ICMI) and the broader history of mathematics education since 1908. Similarly, the International Congress on Mathematical Education(ICME) has played an important role in the direction of Mathematics education since its first congress in 1969. ICME-12 is due to be held in Seoul, Korea from July $8^{th}$ to $15^{th}$ 2012. To date, there has been no research paper concerning the history of the ICMI published in any Korean journal. In readiness for the upcoming ICME-12, this paper aims to provide a comprehensive overview of the history of the IMCI from the perspective of Mathematics education.

Two glycoproteins were purified and biochemically characterized from the lichen X. parietina. Both behaved as enzymes with arginase activity and haemaglutinins. Secreted arginase (SA) contained galactose and glucose in the saccharide moiety and an isoelectric point of 4.54. The algal binding-protein (ABP) had N-acetyl-glucosamine and glucose as glycosidic residues and an isoelectric point of 3.53. Both proteins had the same molecular mass (58.6 kDa) and the same qualitative amino acidic composition. The results allowed us to consider these glycoproteins as isolectins, which have significant physiological roles in the relationship between photobiont and mycobiont of symbiotic association.

This project has been designed for people to experience and understand the process, importance and benefit of coal fire plants. As the biggest and first typical Korean fire plant using coal, Boryeong fire plant has had important roll for the Korean industries. Even so, people has had wrong prejudice for the fire plant in terms of environmental protection. To do these kind of rolls, this museum has been designed with theme, "Boryeong fire plant mating symbiotic relationship between nature, human and technologies." The space was zoned with five major themes: i. circulation of energy in nature, ii. electric power and eco-fire plant, iii. future energy, iv roll for future of environment, v. Korea as the leading energy industry. The design has been developed focused on spatial experiences to make 'Design Sequence' with linear circulations haying several important destinations. The interior has been finished with minimal color and materials projected by big sized movie and various LED movie system. Concept of appordance has been used to make interactive experiences between exhibits and visitors.

남북간의 불균형 무역을 시정하려는 의도에서 발생한 공정무역 움직임은 보다 상업활동 및 판매망에 구체적으로 참여하면서 사회적 성격의 마케팅을 탄생시키게 된다. 윤리적 목표와 상업적 목표를 가지고 있는 공정무역기관이 행하고 있는 사회적 마케팅은 세 가지 소비자유형을 제시하고 있으며 그 접근 방법으로는 제휴를 제안하고 있다.

PVA degrading bacteria were isolated from water system, and identified as Pseudomonas cepacia and Pseudmonas pseudomallei, which were named as Pseudomonas sp. G5Y and Pseudomonas sp. PW. It was found out that those two kinds of bacteria have a symbiotic relationship to degrade PVA. For the mixed culture of these bacteria, the optimal conditions of pH, temperature, nitrogen source, and polymerization degree of PVA were found to be 7.5, $35^{\circ}C$, ammonium sulfate, and 500, respectively. Also, the growth of these bacteria was promoted by trace elements such as vitamin B1, B12, pyridoxine, and p-aminobenzoate, respectively. The specific growth rate of mixed bacteria was inhibited when the concentration of PVA was more than 20g/l. The substrate inhibition kinetics of the mixed culture was $${\mu}=\frac{0.065S}{2.56+S+(S^2/156}hr^{-1}$

Legume plants develop root nodules to recruit nitrogen-fixing bacteria called rhizobia. This symbiotic relationship allows the host plants to grow even under nitrogen limiting environment. Since nodule development is an energetically expensive process, the number of nodules should be tightly controlled by the host plants. For this purpose, legume plants utilize a long-distance signaling known as autoregulation of nodulation (AON). AON signaling in legumes has been extensively studied over decades but the underlying molecular mechanism had been largely unclear until recently. With the advent of the model legumes, L. japonicus and M. truncatula, we have been seeing a great progress including isolation of the AON-associated receptor kinase. Here, we summarize recent studies on AON and discuss an updated view of the long-distance control of nodulation.
