In this paper, we consider the potential of a metaverse space that can be expanded infinitely through the reinvention of the metaverse space. In particular, this study attempted to establish a new concept of metaverse space, and to present research models and strategies between technologies and humanities. To perform this, this study revealed problems that can be overlooked through characteristic analysis of the metaverse space and proposed ways to overcome them through in-depth interviews with experts. In this way, interdisciplinary research will contribute to the revitalization of the metaverse content industry in the mid to long term. Therefore, through this study, it is expected that reinterpreted metaverse space can reach a practical realization as a meaningful place of life and a creative space through Yi-Fu Tuan's concept.

The usual definition of and urban resort was a place vastly different from places of daily life such as a theme park or other tourist destination. At the same time, revival of the combination of usual and unusual spaces, in a way like the mixed "Hare"(Special occasion of public event) and "Ke"(Daily life) spaces of communities of old Japan, is part of the idea of urban resorts. And they are places, which start by making a comfortable urban environment for citizens, providing a daily life full of culture and promoting a city′s identity to visitors. if we think about the kinds of structural elements of urban resorts, the usual elements include community, local culture and industry, while the unusual elements include symbols, festivities and interaction. Kobe Wing Stadium is a venue for the 2002 FIFA World Cup hosted by Korea and Japan. The city will build the stadium, but after construction management will be given over to private enterprise, hoping to utilize that sector′s business know how. A competition was held to determine the private executor who would be entrusted with the planning, design, construction and management of the project, considering the conditions of the area, the stadium′s relationship to it and local revitalization. The competition was won by a private enterprise (Kobe Steel Obayashi Group). The them of "Creation of a Sports Community Park" grapples with the large issue of the facility′s relationship with the community. American geographer Yi-fu Tuan coined the word "topophilia" to indicate love of a place. No other word could better describe the desired urban resort nature of the stadium. From this historical perspective it seems that stadiums have great potential as urban resorts. The factor that will determine their success is the attitude of citizens toward them, in short whether they develop topophilia for them or not. We examined the urban resort nature of Kobe Wing Stadium. Regarding daily life, we saw the attempts to revive the local community, the possibility of deepening the local culture and the weakened state of local industry. As a place that is for more than daily life, we saw the certainty of the stadium′s symbolism, its potential as a place for festivities and the test it will face as a space for interaction. Even though several issues are left for future resolution, evaluating Kobe Wing Stadium through these elements of an urban resort, it is clearly founded in the daily life of the community while providing a venue for "Hare"occasions. Fulfilling the roles of an urban resort, it provides many opportunities for local residents to enjoy their and gives visitors a reason to come repeatedly.

Intakes and excretions of zinc and copper were determined for 8 female adolescents (aged 16.4$\pm$0.5 y; body mass index 20.4$\pm$1.3kg/$m^2$; body fat 33.3$\pm$2.5%; bone mineral density of lumbar spine in L2-L4; 0.96$\pm$0.08g/$\textrm{cm}^2$) when they consumed diets basal and high in calcium for 6 days each. All subjects consumed a basal Ca diet containing 800 mg, Korean RDA level of the subjects, and a high Ca diet containing 1200mg, RDA plus 2 SDs of calcium intake. The diets provided 58% of energy intake as carbohydrate, 25% as fat, and 17% as protein. Food, urine and fecal samples were collected during the last 3 days of each feeding period and were assayed. Mean daily intakes on the basal and high calcium diets, respectively, were 6.57 and 6.37 mg for zinc and 910 and 812 $\mu\textrm{g}$for copper. Fecal excretion of copper and zinc in relation to intake was significantly greater on the high calcium than on the basal calcium diet. Hence, apparent absorption rate was significantly lowered from 98.7% on the basal calcium diet to 97.9% on the high calcium diet for zinc from 66.3% to 56.4% for copper, respectively. Urinary loss of copper was not detectable but that of zinc was 0.38mg on the basal diet and 0.47mg on the high calcium diet. Copper retention was 899$\pm$105$\mu\textrm{g}$/day on the basal calcium diet and 792$\pm$20.8$\mu\textrm{g}$/day on the high calcium diet, and zinc retention was 3.95$\pm$0.91mg/day and 3.11$\pm$0.89mg/day. Thus, copper and zinc retention was significantly decreased on the high calcium diet (p<0.05). Summarizing the results, apparent absorption and retention of zinc and copper were significantly decreased by calcium supplementation. Therefore, it is suggested that interactions among minerals should be considered in determining RDA.

The effect of kimchi pill supplementation on plasma lipid concentration of middle aged healthy people were studied. Freeze-dried mustard leaf added (30%) Korean cabbage kimchi and powdered glutinous parch were used to prepare kimchi and placebo pill, respectively. Experimental group if six participants took 3 g of freeze-dried kimchi as a pill daily for 6 weeks which is equivalent to 30 g of fresh kimchi and control group of six people took same amount of placebo. The diet intakes for the kimchi and placebo group fairly remained unchanged during 6 weeks of trial. When the effect of kimchi pill supplementation was expressed as average percentage changes based on each individual changes, the plasma triglyceride concentration of kimchi pill group was sig-nificantly decreased by 16.8% during trial (p<0.05)while that of placebo group increased by 9.8%, But no changes in plasma and LDL cholesterol concentrations of both groups were observed. HDL cholesterol of kimchi pill group significantly increased by 11.7%(p<0.05), therefore the ratio LDL/HDL cholesterol was significantly decreased by 6.7%(p<0.05) while that for the placebo group increased. The atherogenic index at the kimchi group was also significantly decreased by 10.8%(p<0.05). Kimchi supplementation seemed to have beneficial effects on controlling plasma triglyceride and HDL cholesterol in middle aged men.
