The purpose of this study is to analyze the preference of spatial elements for common space planning in senior congregate housing. For the study, 500 potential consumer's residing in Seoul was surveyed using the questionnaire in the social survey methodology. As for the common spaces, gardens, treatment, and exercise rooms were preferred. A combination of both separate and group arrangement of the buildings was preferred, indicating that people wanted separation of the common space and the individual living units. Second, people preferred sharing parts of the common space with their neighbors and as is the traditional custom, preferred to take off their shoes at the entrance to individual units. Third, for the furniture and facilities, they wanted the manager room in the lobby, the small meeting rooms in the public dining room, a fitness center in the activity room, the rack or alcove to store items in front of an individuals unit in the hallway, a chair to sit down in the elevator, and the chair to rest on the stairway landing. Fourth, in terms of priority for planning the senior citizens' community housing, safety, familiarity like a regular home, reduced isolation and loneliness, sense of belonging, economic factors, aesthetic appreciation, daily life supplement, variety, and self-identity were answered in that order.

The purpose of this study is to consider the idea and the background of the establishment of master plans for parks and green spaces of metropolis in Japan, China and Korea after a careful comparative review of layout planning of green areas, plan objectives, future images and main measures. The method of study is the analysis of the control and plans in these three countries. The study reveals the characteristic of each plan as follows: 1) the conservation and revitalization of the shape of land and the river system in Tokyo; 2) the materialization of ideal green spaces in Beijing, the combination of the ring green and the radial layout of parks and green spaces; 3) the combination of cruciform greenery and the utilized existing public open spaces in Seoul. The result also shows that these cities have the different development of projects but face the common challenges.

In this paper, a new iterative scheme based on the extra-gradient-like method for finding a common element of the set of fixed points of a finite family of nonexpansive mappings and the set of solutions of modified variational inequalities in Banach spaces. A strong convergence theorem for this iterative scheme in Banach spaces is established. Our results extend recent results announced by many others.

In this paper, we introduce S-metric spaces and give their some properties. Also we present a common fixed point theorem for multivalued maps on complete S-metric spaces. The single valued case and an illustrative example are given.

In 2008, Al-Thaga and Shahzad [Generalized I-nonexpansive selfmaps and invariant approximations, Acta Math. Sinica, 24(5) (2008), 867-876] introduced the notion of occasionally weakly compatible mappings in metric spaces. In this paper, we prove some common fixed point theorems for families of occasionally weakly compatible mappings in Menger spaces using an implicit relation. We also give an illustrative example to support our main result.

We prove the existence of common fixed points for three self mappings satisfying contractive conditions in d-complete topological spaces. Our results are generalizations of result of Troy L. Hicks and B. E. Roades[Troy L. Hicks and B. E. Roades, Fixed points for pairs of mappings in d-complete topological spaces, Int. J. Math. and Math. Sci., 16(2)(1993), 259-266].

In this paper we establish two common fixed point theorems in fuzzy metric spaces. These theorems are generalisations of the Banach contraction mapping principle and the Kannan's fixed point theorem respectively in fuzzy metric spaces. Our result is also supported by examples.

In this paper, we propose and study an implicit iteration process for a finite family of total asymptotically quasi-nonexpansive mappings and a finite family of asymptotically quasi-nonexpansive mappings in the intermediate sense in convex metric spaces and establish some strong convergence results. Also, we give some applications of our result in the setting of convex metric spaces. The results of this paper are generalizations, extensions and improvements of several corresponding results.
