본 연구는 주부들의 주활동공간인 부엌가구와 공간의 설계에 있어사용하기 편리하며 가사활동에 따 른 피로를 경감시키고 요통과 같은 주부직업병을 예방할 수 있는 부엌가구와 공간의 개발에 그 목적을 두었다. 연구는 먼저 수도권의 32평형 규모의 아파트150가구를 대상으로 설문조사를 실시하였으며, 만 24시간동안의 실제 가사활동을 Video로 촬영하여 동작분석을 실시하였다. 그 결과 주부들은 수납의 용 이성과 공간의 크기, 작업대의 높이 등을 가장 많은 개선사항으로 지적하였으며, 절반이상의 주부들이 앉은 자세에서 작업이 이루어졌으면 좋겠다고 응답하였다. 또한 동작분석 결과 작업의 70%이상이 개수 대를 중심으로 조리대와 가열대 주변의 한정된 공간에서정적으로 선 자세에서이루어지는 것으로 파악 되었다. 이러한 선 자세에서의 작업에 따른 피로도를 감소시키기 위하여 입좌식 의자를 도입하였으며, 개수대를 씽크대의 'ㄱ'자 코너에 위치하여 주방활동시의 이동거리를 단축하고자 하였다. 피로도의 경감 을 측정하기 위하여 입좌식 의자를 도입한 개선된 씽크대와 기존의 입식씽크대에서 가사활동시 요구되는 주부들의 에너지 대사량을 비교하기 위하여 심장박동수와 산소호흡량을 측정하였다. 실험결과에 따르면 주방에 입좌식의자를 도입한 경우가 가사활동에 요구되는 에너지 소모량이 심장박동수와 산소호흡량의 기준에서 각각 평균적으로 30%와 57.5% 이상이 감소하는 것으로 파악되어 이러한 부엌가구의 도입으로 주부들의 가사활동에따른 피로도가 절반 가까이 감소될 수 있음을 니타내었다. 또한 부엌가구의 재배치 에따른 가사활동시 이동거리가 평균적으로5.5%이상이 감소하는 것으로 나타났다. 본 연구결과를 주방설 계에 적용할 경우 가사활동의 효율성과 편리성이 향샹됨은 물론 가사활동에따른 피로도를 경감 시키고 요통 등의 주부직업병을 예방할 수 있을 것으로 기대된다.1일 1회씩 4회 투여한 군에서도 암수에 상관없이 전 농도 군에서 염색체이상을 나타내지 않아 유전독성을 나타내지 않음을 관찰하였다. 특히 vitamin C와 E의 병용투여는 상승적으로 적용하여 간세포손상을 더욱 억제시킴을 알 수 있었다.mance and on TFP(Total Factor Productivity) growth which is a pure measure of firm performance. To utilize the advantage of panel data, FEM(Fixed Effect Model) and REM(Random Effect Model) were used. The empirical result shows that the entropy index as a measurement of inter-business relatedness is not significant but technological relatedness index is significant. OLS estimates on pooled data were considerably different from FEM or REM estimates on panel data. By introducing interaction effect among the three variables for business portfolio properties, we obtained three findings. First, only VI (Vertical integration) has a significant positive correlation with ROS. Second, when using TFP growth as an dependent variable, both TR(Technological Relatedness) and f[ are signif

Today, the most important factor affecting the quality of human life is thought to be due to the environment. The importance of environmental monitoring systems to improve human life and improve welfare as the magnitude of the damage increases year by year due to the rapid increase in the frequency of hail, typhoons, collapse of incisions, landslides, etc. Is increasing day by day. Among environmental problems, problems caused by water quality have a very high proportion, and as there is a growing concern that the scale of damage will increase when water pollution accidents occur due to urbanization and industrialization, the demand for social water safety nets is increasing. have. In the last 5 years, 259 cases of water pollution (Han River 99, Nakdong River 31, Geum River 25, Seomjin River and Yeongsan River 19, and 85 others) have occurred in the four major river basins. Caused damage. Therefore, it is required to establish a water quality environment management strategy system based on big data that can minimize the uncertainty of the water quality environment by expanding the target of water quality management from the current water quality management system centered on the four major rivers to small and medium-sized rivers, tributaries/branches, and reservoirs. In this paper, we intend to construct and analyze a water quality monitoring system based on big data that can present useful water quality environment information by analyzing the water quality information accumulated for a long time.

As industrial safety increases, various industrial accident prevention technologies using smart factory technology are being studied. However, small and medium enterprises (SMEs), which account for the majority of industrial accidents, are having difficulties in preventing industrial accidents by applying these smart factory technologies due to practical problems. In this study, customized monitoring and warning systems for each type of industrial accident were developed and applied to the actual field. Through this, we demonstrated industrial accident prevention technology through appropriate smart factory technology used by SMEs. A customized monitoring system using vision, current, temperature, and gas sensors was established for the four major disaster types: worker body access, short circuit and overcurrent, fire and burns due to high temperature, and emission of hazardous gas. In addition, a notification method suitable for each work environment was applied so that the monitored risk factors could be recognized quickly, and real-time data transmission and display enabled workers and managers to understand the disaster risk effectively. Through the application and demonstration of these appropriate smart factory technologies, the spread of these industrial safety technologies is to be discussed.

The Embedded system provides human-centric services in many fields of education, information, industry and service, and monitoring programs have been variously developed for managing, controlling and testing for these embedded systems. Currently, many kernel trace toolkits are being used for monitoring. These trace toolkits are so complicate that we present $ETT^{plus}$, our simple and explicit embedded kernel trace toolkit, for embedded systems and describe the transmission method for trace data between the embedded target system and the host system. $ETT^{plus}$ provides the solution to solve the problems such as the difficult kernel patch and file system dependency in existing kernel trace toolkits like LTT. Furthermore, we present the experimental results about embedded system performance evaluations such as system call execute time or network data transmission time by using $ETT^{plus}$.

Today the computerization in overall civil life is globally progressing, and software plays a central role in all interdisciplinary areas of society. These changes of information environments lead to the change of values and paradigm shift, and the change of Korean educational policies is also happening. As human-machine interaction is becoming ubiquitous, code literacy is going to play an important role before long. Despite these transitions, information education in universities in Korea focuses on just driving application programs. In this paper, we explore overall educational system and curriculum of universities in Korea. And we present educational factors corresponding to educational levels and contents. Presented five factors coupling three educational contents and three educational levels may be dedicated to design curriculum.

The use of gestures provides an attractive alternate to cumbersome interface devices for human-computer interaction. This has motivated a very active research area concerned with computer vision-based analysis and interpretation of hand gestures. The most important issues in gesture recognition are the simplification of algorithm and the reduction of processing time. The mathematical morphology based on geometrical set theory is best used to perform the processing. A key idea of proposed algorithm in this paper is to apply morphological shape decomposition. The primitive elements extracted to a hand gesture include in very important information on the directivity of the hand gestures. Based on this characteristic, we proposed the morphological gesture recognition algorithm using feature vectors calculated to lines connecting the center points of a main-primitive element and sub-primitive elements. Through the experiment, we demonstrated the efficiency of proposed algorithm. Coupling natural interactions such as hand gesture with an appropriately designed interface is a valuable and powerful component in the building of TV switch navigating and video contents browsing system.

Exhibit space is result that various kinds works of architecture design, interior design, plan and control of exhibit program, embodiment to display space, operation and administration etc. are formed accomplishing creation. Because exhibit space must consider interaction of value that is in dwelled along with the external form about human and exhibits. Therefore, display space of exhibition must achieve functional role that can accomplish communication with spectator as well as function as place that possess products of accumulative value. Therefore, we must establish effective communication plan by position and form of display space as well as properly of exhibits, display contents, exhibit program to achieve purpose of trade fair display. Display space of trade fair can be classed by wall style, corner style, head style, island style, two entrance style 5 according to the position. And we must plan communication plan by these position dividing the function to passive communication area, active communication area, intensive communication area, function achievement area. We will can grope contents and method for successful exhibit through communication plan that is connected form and position of exhibit between exhibit space of such trade fair and we may achieve purpose of trade fair display.

This paper presents a model to estimate the amount of $CO_2$ emitted by cars in cities. Based on the spatial configuration of street networks, building masses and usages, it first develops a deductive model to combine them in a way to account for $CO_2$ emission amount by cars. It then proceed to validate model behaviours through a series of simulations on some ideal urban settings and finally calibrate it following its real application to the five case study cities in Korea. In contrast to the conventional 'top-down' approaches, we expect our model to have high utilities, particularly in the field of urban planning and design, where we cannot but deal directly with the spatial configuration of urban components and microscopic human activities.

The development and operation of the MASS (Maritime Autonomous Surface Ship) is being actively discussed for more efficient and safer maritime transportation solutions. The autonomous navigation technology has positive aspects such as the prevention of marine accidents, improvement of fuel efficiency of ships and cost reduction, and negative aspects such as job loss, task change, and security problems. It is expected that there will be new human element issues such as the situation awareness of remote operators, because the shore-based control will be conducted when fully autonomous ships are in operation. In this paper, we consider major human element issues that should be factored in the development and operation of MASS, and suggest a method of HRA (Human Reliability Analysis) for P IFs (Performance Influencing Factors) of the remote operators that are expected according to the shore-based control.
