The purpose of this study is to research the environmental amenity factors of a city to devise the strategies to preserve the factors. For this study, the area of Masan city in Korea was chosen, and questionnaires, field studies, and statistical researches were used. Based on the results, the research showed the city surveyed had expanded by 1,069%, and the population of the city had increased by 272% from 1970 to 1995. In the city-life environment, the traffic was not smooth and the streets were not safe. The number of cars increased by 40,797% from 1970 to 1995, but the total length of roads increased only by 333%. The number of traffic accidents increased by 850%. Buildings were not preserved or maintained and did not have any traditional value. Additionally, buildings were not harmonious with environmental surroundings. Land allocation for utilization was not mixed well with tradition. In relation with the surroundings, there were not enough spaces for old people, and parking spaces were limited. In the field of public policy and finance, economic support and fundamental facilities were not enough. The survey of the household environment and the neighborhood environment showed that the room temperature, sunshine, air condition, and space were medial in the household environment. Public social facilities and entertainment culture had the lowest quality in the neighborhood environment. The city-life environment, the neighborhood environment, and the household environment affected the quality of life in order. The above results showed that cities should be planned upon sustainable development with the idea of emphasizing ecological harmony and considering people first, that citizen should be planned upon sustainable life by the harmony between people and the environment. Cities should be places where all people can live together pleasantly and cooperate with each other.

The role of urban agriculture should not be limited as a small-scale crop cultivation activity as it was, but it has to be considered as an entire process of a agriculture activity for the restoration of the city community. This study is based on the assumption that there has been a significant change in urban lifestyle and urban farming preference, considering the overall improvement in standard of living after implementation of five day work week system. It was conducted for urban citizens who were interested in actual urban agriculture for ages 19 and over who visited the Korea Urban Agriculture Exhibition in 2018. Only 115 valid samples were used for the empirical analysis. To analyze the demographic characteristics and effects of urban agriculture, frequency analysis and descriptive statistics were conducted. In order to analyze the reliability and validity of the measurement variables of the effect, the variables that deteriorate the validity were removed and 15 variables of the urban agricultural effect were selected. According to the result of factor analysis, three factors were extracted as follows: socially sustainable effect, negative effect and economically sustainable effect. In order to examine the effects of urban agriculture depending on income level, the one-way ANOVA, which is a statistical technique for verifying differences in the sample means, was performed. The psychological stability of people, the recovery of humanity through communion with nature, and the vitalization of agriculture linked with local agriculture had significant correlations with income level. The negative effect showed no significant correlation with income level. The improvement of the local environment was found to have an impact in relation with income level. We expect that there will be more studies on policies for the new types and models of urban agriculture in order to make it easier for urban citizens to approach it.

This paper revisited the key advances on System Dynamics modeling about traditional macro-economic models and economic growth structures, and then tries to elaborate a new model based on the endogenous growth theory that incorporates new growth factors, relevant to knowledge/technology as well as the Environment, into traditional growth models. Accordingly, the new model augments the acceleration and multiplier loops and the balancing ones representing market clearing mechanism with a simple numerical example. The authors thus provides macroeconomic System Dynamics analysts with a milestone to model macro-economic structures reflecting on traditional and cutting-edge theories on sustainable economic growth and general equilibrium modeling.

The purpose of this study is to provide the planning factors of housing for the disabled and elderly based on the inclusive housing design as sustainable neighborhood. The goal of inclusive design is to make buildings and communities more livable for all type of people. Inclusive design should embrace other good design goals and reinforce them, not work against them. To carry out this purpose, we should proceed in the following way: First, we deducted the four design factors (the basic, recommendable, adaptable, and residential factors) by reviewing the characteristics of inclusive housing concepts. Second, we analyzed the related foreign design standards and guidelines such as the ICC/ANSI A117.1 Type C Units (the United States, 2009), Lifetime Standard (the United Kingdom, 2010), and Livable Housing Design Guideline (the Australian, 2010) through four design factors based on inclusive design concepts. Finally, we suggested the housing design factors for the disabled and the elderly in Korea. To conclude, we can make the followings: It is important basic factor that the bedroom and bathroom layout closed to each other. Also, the bedroom has the proper height of light switches, outlets, and windows. The recommendable factors take into consideration stairs and ramp, if existent. The adaptable factors are closely related to domestic housing culture as well as residential factors. Proceeding from this fact, the livability for people with disabilities and older requires accessibility and adaptability that take into account public and efficiency considering the current trend of housing development and urban planning.

지속가능한 경영과 직무전문성을 확보하는 것이 현대 조직의 지상과제가 되고 있다. 이런 전문성 연구는 전문가의 구성 요소에 중점을 두는 것이 대다수인 반면, 지속가능경영을 목표로 구체적으로 수치화하여 측정하고 가야 할 목표를 제시할 수 있는 전문성 진단 측정요인과 방법에 대한 연구는 극히 부족한 편이다. 이에 따라, 이 연구는 객관적이고 신뢰성이 높은 전문성 진단 측정 요인 발굴과 측정요인들 간의 관련성을 제시하였다. 이 연구는 전문가 및 전문성 정의, 전문성 구성 요소의 재정립, 전문성 구성요소의 기준 정보와 측정요인들의 가중치 결정 방법 등을 통해 전문성 진단 측정 방법을 제시하였다. 이 진단방법에 의해 나타난 결과는 기존 역량평가 및 진단도구와 상당한 상관성이 있는 것으로 분석되었으며, 내용타당성을 충족하였다. 이와 같은 연구결과와 함께 사회적 전문성 구성 체계를 국가차원에서 수립할 것을 시사점으로 제언하고자 한다.
