It is not surprising that senior centers are widely used nationwide as Korea becomes an aging society. This study attempts to figure out senior citizens' needs and evaluations of senior centers in terms of characteristics of their usage and spatial composition. A face to face interview using a questionnaire was conducted on 255 senior citizens who has been using senior centers located in Jangyu new city apartment housing complex. The questionnaire is composed of questions asking characteristics of their usage, evaluations of spatial composition, and respondents' demographic data. Findings are: First, it is found that many respondents visit senior centers everyday and spend 4 to 6 hours a day. Their main activities are meeting friends, taking hobbies, and dining. That is, senior centers play a pivotal role in daily lives of senior citizens. Such characteristics should be taken into account in space design when planning to build a future senior center; Second, it is found that senior centers play a role of auxiliary space for building their sense of belonging and familarity. It is found that furnitures in senior centers are worn out and safety measures are not sufficiently considered; Third, it is found that they highly evaluate flexible spacial composition that could be partitioned or extended depending on occasions even though they prefer independent space; Fourth, it is found that kitchen facilities are not large enough considering the fact that more that half of the respondents have their lunches in senior centers. Even though they do not cook for themselves kitchen space should be large enough for preparing meals simultaneously for a large number people.

In the spatial image composition of a cathedral, light is the most important element of changing the mind through vision. The religious meaning of light and its impact on human sensibility are believed to be very large. Therefore, in this study, 'Illuminance' is the most important research subject of a cathedral's worship space lighting plan elements. Illuminance is expressed by giving the clarity and form of space through a subtle spatial composition difference. The role of illuminance is essential for confirming the existence of space, and lighting controls the spatial atmosphere at an appropriate level. The standard and range of illuminance are set through the synthesis and analysis of related standards. Based on this, a related case study was conducted on cathedrals built in the Gangnam area of Seoul in the 1980s. The lighting-related factors were analyzed and the illuminance of the liturgical space and worship area were measured. The appropriate level of applicability was confirmed by comparison analysis. A plan for the illuminance application levels and elements applied in the cathedral lighting design is proposed.

The purpose of this study was to investigate the spatial composition characteristics of elderly housing facilities in Korea, in order to refer them in establishing the basic plan for elderly housing in Korea. The case study performed in this study from October 16 to October 31 is based on ten housing facilities for the elderly in KOREA. During the site visits, the interview with the custodians, survey of the space, picture taking and diagram gathering were carried out. The results of this study were as follows; 1. The type of floor plan was classified into ㅁ type, L type, and ㅡ type. And they hadn't an outside space called a garden(courtyard). 2. The kinds of common spaces could be grouped as the space for basic living, for leisure, and for convenient living. Also it was all common that the housing facility had common diningroom laundry room once, and activity room. The type of the common spaces was categorized into three types, the centralized type where the shared space was located at the center of the housing facilities, the distributed type, depending on the degree of separation between common spaces and units, and another each building type. 3. The kinds of units was classified into studio, oneroom, one bedroom and two bedroom. 4. Elevator, safety grab bar, emergency bell, and the door handle of lever or bar type were placed in these facilities.

While several recent studies have investigated the spatial distribution of entrepreneurship within the Seoul metropolitan area, they have not thoroughly examined the relationship between the industrial composition and spatial distribution of entrepreneurial clusters. To address this gap, this study initially identified entrepreneurial clusters through hotspot analysis using Getis-Ord Gi* with venture capital investment data from 2021. Subsequently, to analyze the industrial composition of the identified clusters, we measured not only their industrial diversity and specialization, but also the share of software and non-software industries. Additionally, we examined the government policies related to the formation of the clusters. As a result, we identified fourteen prominent entrepreneurial clusters within the Seoul metro area and revealed that the clusters located closer to the city centers exhibited higher levels of industrial diversity and a greater share of software industries. Conversely, clusters situated farther from the city centers demonstrated a higher share of non-software industries. Furthermore, we found that government policies affect the industrial specialization of suburban clusters. Nevertheless, we observed several exceptions that diverged from the general trends due to policy interventions. These findings underscore that formulating policies for entrepreneurial clusters in metropolitan areas should be based on these insights.

In application and discussion of population structure and phenotypic divergence in plant community, the classic Lotka-Volterra models of competition and spatial model are conceived as a mechanism that is composed by multiple interacting processes. Both the Lotka-Volterra and spatial simulation formulae predict that species diversity increases with genotypic richness (GR). The two formulae are also in agreement that species diversity generally decreases within increasing niche breadth (NB) and increases with increasing potential genotypic range (PGR). Across the entire parameter space in the Lotka-Volterra model and most of the parameter space in the spatial simulations, variance in community composition decreased with increasing genotypic richness. This was, in large part, a consequence of selecting genotypes randomly from a set pool.

Installation art in 20th century shows an expanded trend as a result of material, time, or spatial expansion of subject, therefore subjects could be either materials or non-materials. This trend says that three elements-objet, space, and spectator-is inseparable essence of installation art. Nowadays, the borderline between installation art and everyday human life is getting indistinctive, and both Installation art and human life are becoming a part of another. By adapting the flexibility of installation art into the interior space, more interaction could happen, therefore, people will recognize spatial and visual character of Interior space as a visually satisfying Installed object. The main goal of this study is to understand changing of spatial composition in consequence of expressional variety as a result of dispersion of spatial elements. Especially, this study gives a fundamental ideas about private character of installations art in commercial spaces and expressional character of modern installations.

전자해도를 시스템에 사용하기 적합하게 변환한 구조를 SENC(System Electronic Navigational Chart)라고 한다. SENC의 구조는 전자해도 표출에 필요한 각종 공간질의, 속성질의 등의 처리, 개체 속성정보의 관리, 그리고 개체의 화면표출을 위한 정보 관리가 용이하도록 정의되어야 한다. 현재 대부분의 SENC는 파일기반으로 구현되어, SENC를 활용하는 시스템에서는 SENC의 정보들을 처리하기 위한 질의를 시스템 내에서 정의하고 처리하여야 한다. SENC를 파일이 아닌 검증된 Spatial DBMS에 구현하여 SENC가 갖추어야 할 각종 정보 관리 및 처리 기능 구현 시, 시스템의 신뢰성과 유연성에 이점을 가져올 수 있다. 본 논문에서는 기본적인 전자해도 정보 관리 및 표출에 필요한 SENC의 특성을 고려하여 Spatial DBMS를 이용하는 SENC 설계를 연구하였다.

There has been increasing interest in UHPC (Ultra-High Performance Concrete) materials in recent years. Owing to the superior mechanical properties and durability, the UHPC has been widely used for the design of various types of structures. In this paper, machine learning based compressive strength prediction methods of the UHPC are proposed. Various regression-based machine learning models were built to train dataset. For train and validation, 110 data samples collected from the literatures were used. Because the proportion between the compressive strength and its composition is a highly nonlinear, more advanced regression models are demanded to obtain better results. The complex relationship between mixture proportion and concrete compressive strength can be predicted by using the selected regression method.

Hyperspectral images feature a relatively narrow band and are easily disturbed by noise. Accurate estimation of the types and parameters of noise in hyperspectral images can provide prior knowledge for subsequent image processing. Existing hyperspectral-noise estimation methods often pay more attention to the use of spectral information while ignoring the spatial information of hyperspectral images. To evaluate the noise in hyperspectral images more accurately, we have proposed a spectral-spatial cooperative noise-evaluation method. First, the feature of spatial information was extracted by Gabor-filter and K-means algorithms. Then, texture edges were extracted by the Otsu threshold algorithm, and homogeneous image blocks were automatically separated. After that, signal and noise values for each pixel in homogeneous blocks were split with a multiple-linear-regression model. By experiments with both simulated and real hyperspectral images, the proposed method was demonstrated to be effective and accurate, and the composition of the hyperspectral image was verified.
