We propose a task and motion planning algorithm for clearing obstacles and wiping surfaces, which is essential for surface disinfection during the pathogen disinfection process. The proposed task and motion planning algorithm determines task parameters such as grasping pose and placement location during the planning process without using pre-specified or discretized values. Furthermore, to quickly inspect many unit motions, we propose a motion feasibility prediction algorithm consisting of collision checking and an SVM model for inverse mechanics and self-collision prediction. Planning time analysis shows that the feasibility prediction algorithm can significantly increase the planning speed and success rates in situations with multiple obstacles. Finally, we implemented a hierarchical control scheme to enable wiping motion while following a planner-generated joint trajectory. We verified our planning and control framework by conducted an obstacle-clearing and surface wiping experiment in a simulated disinfection environment.

We determined the contents of 11 biogenic amines in 20 types of cabbage kimchi, 10 types of fish sauce, and 40 types of salted fish purchased from small- and medium-sized grocery stores in Gyeonggi-Do, Republic of Korea, from June to October 2017. The content of each of the biogenic amines in the various types of cabbage kimchi was slightly lower than that in detection amounts of each of the 10 types of biogenic amines and the values reported by Joe et al. The histamine content of all five types of anchovy sauce was lower than the limit set by the European Union (400 mg/kg), but that of three of the five types of sand lance sauce was higher. Analyzing the ratios of the contents of five highly toxic biogenic amines to those of the 11 biogenic amines yielded no quantitative correlation. The estimated daily intake of the five highly toxic biogenic amines in cabbage-kimchi and fermented fish was ${\leq}6mg$.

Purpose: As declines in the quality of residential environments occur, such as urban heat island effect, tropical night phenomenon, and violations of right to light and privacy due to urban densification and high rise building, these problems are emerging as social issues. In order to improve these issues, design factors which consider environmental aspects must be selected when planning apartment complexes, and ways to reflect them in the planning phase must be explored. Method: In this study, the analytical hierarchy process(AHP) was used to deduce design factors that considered environmental elements during the planning of apartment complexes. Furthermore, the priority and weight for each evaluation index were assessed. The objective was to propose a guideline for planning apartment complexes by finding the best solution for each evaluation index using complex weight values. Result: Floor area ratio was selected as the most important evaluation criterion in the environmentally conscious evaluation index for apartment complex planning. The shape and placement of skylights were selected as the most important evaluation criteria in the sunshine environment for a pleasant residential environment. Ground surface cover design was selected as the most important criterion in the outdoor thermal environment index for improving the microclimate within cities and apartment complexes. Thus, the results of this study can serve as an investigation guideline that concerns policy and regulations, and as reference data that can be used in planning apartment complexes.

최근 국토의 난개발이 발생하면서 자연생태계가 훼손되고 있어, 환경부는 기존의 사후관리와 통제중심의 환경정책에서 사전예방과 자율적 환경관리 정책으로 환경정책기조를 전환하고 있다. 자연환경 보전계획은 생태계와 야생동 식물을 보호하는데 초점을 맞추고 있어 국토 전체의 자연환경을 체계적으로 보전하는 데 한계가 있다. 이러한 한계를 극복하기 위해서는 자연환경보전계획의 공간화와 국토 도시계획과의 연계성을 강화하는 것이 필요하다. 이에 본 연구에서는 지자체 자연환경보전계획의 수립실태와 문제점을 진단하고, 그러한 자연환경 보전계획이 국토 도시계획과 유기적인 연계를 확보하기 위해 어떠한 방향으로 수립되어야 하는지 제시한다. 구체적으로 자연환경보전계획의 체계를 개편하는 것이 필요하고, 계획을 매체중심에서 공간환경 중심으로 개편하는 것이 바람직하다. 이를 위해서 도시지역에서는 비오톱지도를 작성하는 것이 바람직하다. 비오톱의 조사내용, 조사방법, 도면화 방법 및 기준이 필요하다. 이와 아울러, 중앙정부와 지방자치단체의 자연환경보전을 위한 합리적인 역할분담 방안을 강구하고, 자연환경보전계획을 효율적으로 수립 추진하기 위한 민관협력체제의 구축방안을 모색하는 것이 중요하다.

The purpose of this study is to develop the evaluation factors for formation of the future - oriented rural residential environment and to derive the importance of this evaluation factors. The main research methods are network analysis using Net-miner, AHP analysis and importance analysis for experts. The main research results are as follows. First, 6 factors for evaluation rural residential environment(environmental-sustainability, communality, self-reliance, aesthetic, enjoyment, settlement), 3 sub-factors of each factors, and key physical facilities(10 for rural center and 28 for rural villages) were derived by literature analysis and network analysis on it. Second, key priority factors that should be considered in physical formation of rural residential environment was deducted by AHP analysis. Improving accessibility of living services in the settlement factor, improvement of garbage collection and wastewater treatment system around the residential area, and ensuring topographic continuity in the environmental-sustainability factor was derived as a priority factors. Third, as a result of evaluation of the importance of physical facilities in the rural residential environment, there was a high demand for cultural welfare facilities in common. However, when compared with the villages where the harmony between the natural environment and the living environment is emphasized, convenience of living and accessibility of transportation were important in the rural center. These results suggest that solving the qualitative conditions as residential environment will help to attract new population. This study will contribute to enhance the qualitative level of the rural residential environment by suggesting strategic priority items when carrying out projects related to the rural residential environment creation in the future.

Ever-developing information and communications technology has changed the ways of life from that of industrial society to the information-oriented community, and is widely used in a variety of social and economic contexts. Besides, urban problems in today's society are intricately involved so that the possibility of any reliable breakthrough may not to be likely. To work out these complicated problems as well as to understand the crux of the matter more comprehensively, ubiquitous urban planning has been laid out, and as a result attempts to reflect this system are cautiously made in metropolitan areas. However, most u-City planning, integrating uibiquitous technology, has focused on creating urban infrastructure and its services, therefore neglecting the importance of housing in urban space. Consequently, thorough u-City planning has yet to be defined in relation with urban space, and housing planning, established on the basis of the user-oriented housing environment, needs to be urgently made. Centering on the importance of housing in the construction of an improved future urban environment, this study aims to discuss the role of urban environment planning where metropolutan residents can enjoy a comfortable and convenient life. As well, this research paper seeks to focus attention on the consideration for users that is often disregarded but requires reflecting in the u-City planning.

Production planning and control system plays an important role in manufacturing companies because it determines all production capacity planning, material procurement planning, and production scheduling which are needed in the process of producing products. Many researches on production planning and control system have been conducted for many manufacturing companies for recent decade. But, a considerable research achievement has mainly been obtained on the forecast-driven production for a make-to-stock and an assemble-to-order. The reason is that there are some hardships such as difficulties of standardizing product information, the frequent changes of design and material, and the unexpected dynamic events that influence the production of customer's order in a make-to-order or an engineering-to-order environments. By these characteristics and their complexities, some studies for production planning and control system in a make-to-order environment are presented recently. In this paper, we present the framework of the hietachical production planning and control for a make-to-order environment with dynamic events. In order to illustrate the usefulness of the proposed framework for a hietachical production planning and control, the information system for a make-to-order production was implemented with the object of the company of producing electricity transformer.

This paper is intended to deduce the planning elements of Eco-village through theory contemplation and preceding researches in order to be used as practical data of resident participating Eco-village by contemplating characteristics demonstrated in planning element utilization methods within the village. Resident participating Eco-village aims for residents who will reside in the relevant village to participate from village plans to construction. Unlike other Eco-village, residents of resident participating Eco-village make decisions autonomically through planning direction, planning elements, discussions and meetings, which are uniquely distinctive from other Eco-villages. It appears, however, that analysis on the planning element utilization methods of resident participating Eco-village is inadequate. There are various methods of village resident participation, and the methods cannot rule out the close relationship with planning elements. Hence, programs for resident participation should be devised at the time of village planning. Resident participating Eco-village should suggest measures and guidelines through finding problems in order to implement sustainable and environment-friendly life that prevent a retrograde step.
