증강현실은 가상현실과는 구별되는 개념으로, 실제 세계와 가상 세계의 요소가 혼합된 상호작용 환경이다. 본 연 구는 가상현실 또는 일상에서 노출될 수 있는 일반적인 콘텐츠를 활용하여, 증강현실이 사용자 경험에 미치는 영향 을 검증하였다. 본 연구에서는 증강현실 사이버 멀미를 유발하기 위해서 조건에 따라 증강현실 노출 시간과 콘텐츠 의 움직임 속도를 조작하였다. 실험 과정에서 참가자는 증강현실 기기를 120분 동안 착용하고 30분씩 시뮬레이션 레이싱 게임을 시청하며 색 변화 탐지 과제를 수행하였고, 그로 인해 유발된 주관적인 불편감을 SSQ 설문지를 이용 해 보고하였다. 실험 결과, 증강현실 노출 시간이 길어질수록 사이버 멀미는 점진적으로 증가하였으며 기기를 해제 한 후에도 사이버 멀미는 지속되었다. 하지만, 움직임 속도는 사이버 멀미에 미미한 영향을 미쳤다. 특히, 메스꺼움 증상과 방향 감각 상실 증상이 높게 유발되는 가상현실과는 다르게 증강현실은 안구 운동 불편감에 대한 보고가 높게 관찰되었다. 본 연구는 증강현실 경험이 가상현실 경험과는 구별됨을 보여주며, 증강현실 경험으로 유발될 수 있는 인체 영향성을 다면적으로 측정했다는 점에서 의의가 있다.

전체 김치시장 규모는 2조 3,886억으로 자가제조 1조 2,300억, 상품김치 1조 1,586억 규모이며, 그 중 상품김치는 업소용을 제외하고 가정용의 경우 약 3,000억 규모로 이중 리테일은 2,098억으로 추산된다. 현재의 시장규모에서 2025년까지 상품김치 시장은 어떤 규모로 변화될지 몇가지 지표를 바탕으로 예측해 보면 아래와 같다. 대한민국 가구 구조변화, HMR 취식트렌드 등의 식생활 패턴 변화, 김치조달방식 변화등으로 자가제조 김치시장에서 매년 약 1.9%씩 포장김치로 수요가 전이될 때 2017년 16%에서 2020년 19.6%, 2025년 25.6%로 성장될 것으로 전망되며 김치시장은 B2C기준 2020년 5,158억, 2025년 7,863억으로 예측된다. 인구감소와 1인당 김치취식량 변화에 따라 김치시장의 성장이 둔화, 축소되는 것이 아니라 식생활의 패턴과 김치조달 방식의 변화로 자가제조 시장에서 전이되면서 포장김치 시장의 성장율은 더 빠르고 클 것으로 예측된다. 반면, 2032년을 기점으로 인구 증가율이 마이너스로 전환되고, 노령화에 따른 15세~64세 인구가 빠르게 감소되어 가용 노동인구의 감소가 예상된다. 또한 근로자의 노동시간은 단축되는 반면 노동임금은 증가되고 있으며 노동환경 역시 빠르게 변화되고 있다. 김치의 경우 김치가 상품화 되기 시작하였던 1980년대 대비 상당부분 설비를 이용한 기계화, 자동화가 부분적으로 도입되어 수작업 의존도가 많이 낮아졌다. 그러나 포장김치 시장으로는 한국의 약 3배에 이르는 일본과의 제조경쟁력을 비교하였을 때에는 아직도 해결해야 되는 숙제들이 많은 것이 현실이다. 그럼에도 김치세계화를 위해 세계김치연구소와 기업을 중심으로 제조공정 자동화에 대한 연구가 활발히 진행되고 있으며, 일부 자동화 설비가 제조현장에 도입/상용화 되고 있는 것은 바람직하다고 할 수 있겠다. 향후 성장하는 김치시장에 대응하고 김치세계화를 위해서 제조경쟁력은 더 이상 선택이 아닌 필수요건임에는 의심의 여지가 없는 부분이다.

The purpose of this study was to investigate the status of domestic and foreign power blogs that serve as professional source of information and to clarify the difference of the criteria for the certification and selection of power blogs. The study also analyzed the configuration of contents and the characteristic of categories of the power blogs. Eleven domestic blogs were examined, of which ten were certified as power blogs on several portal sites and one blog was operating in English. Furthermore twelve foreign blogs were examined, of which ten blogs were selected from the graded list of www.alexa.com for the Fashion Power Blog TOP 20 adopted on www.telegraph.co.uk in 2009, and two noticeable blogs were selected additionally. Data were analyzed by both theoretical and exploratory studies. The exploratory study was conducted by fourteen majors, who took interest in the blogs and were divided into two groups to look at the domestic and foreign sites, from 12 October to 12 November in 2010. The types of blogs were classified by frequency analysis of interactivity, interest provision, information provision and purchase capability. The investigators checked the type of the contents of each blog and the frequencies were used for the classification type. The analysis showed that the frequencies were in the order of information provision, followed by interest provision, and purchase capability for foreign blogs, while interest provision was followed by information provision for domestic blogs. Interactivity, interest provision, information provision and purchase capability were generally reflected in foreign blogs. Rather than interest provision and information provision, however, interactivity and purchase capability were reflected relatively weakly in domestic blogs.

This study was designed to analyse the performance and the mechanisms of workers' participation and communications in industrial accident prevention activities leading to the reduction of industrial accidents. This study also aimed to find out the causal relationship influencing the promotion of prevention activities of industrial accidents. Of the manufacturing businesses with more than 5 workers as the population of the survey, a questionnaire was conducted with 2,500 workspaces chosen by stratified sampling. Out of 2500 workspaces, 971 workspaces equipped with industrial safety and health committee were analysed in this study. According to the results of this study, the primary influential factors on safety activities were the management of industrial accidents and the cooperations between supervisors and workers on site. The secondary influential factor was the establishment of industrial safety and health committee. Regarding the effectiveness of industrial accident reduction, -0.01 was shown by workplace safety activities by themselves and -0.09 was shown by participation and communications through indirect safety activities. This indicated workers' participation and communications play an important role in the reduction of industrial accidents. By discovering the clue to the mechanism of the workers' participation and communications, this study is expected to stimulate the reduction of industrial accidents by emphasizing the importance of workers' participation and communications in resolving the safety and health problem in the workplaces.

This study was planned to investigate what the main factor of the regulation compliance of inspection on harmful machine, instrument and equipment by industrial safety and health act is. This study subject was composed of three groups as employers, employees of manufacturing and using the harmful machine and safety inspectors. Manufacturing workplace were 236 places, using workplace were 201 places and the safety inspectors were 100 people. The study subject was sampled by stratified random sampling considering the type of harmful Machine. Data for analysis is collected from each sample using interview with structured questionnaires. Compliance is measured by 2, 3, and 4 point scale composed by 8 sub items such as general perception, understanding, clearness, necessity, relevancy, implementation, penalty, and general compliance of the regulation. The level of 8 items of employer's compliance are not differentiated among three groups. The determining factors for inspection observance of the workplace using the harmful Machine were understanding, penalty and cognized compliance. The determining factors for inspection observance of the workplace manufacturing the harmful Machine were understanding and object conformity. These results show that the strategy to adapt the regulated group to inspection regulation will be the elevation of understanding for regulation first of all.

Recently in Korean Society, risk and safety has become a central discourse in not only the social and natural science but also political decision making. The efficient organizational management contributes to controlling the risk factors in the workplace. For the management is influenced and improved by the organizational culture, the alternatives more than simply improving the work environment or enforcing the education of safety on each workers are required. This study was the status of safety culture in organizational members(managers and workers, and specialist) including the attitude on the safety atmosphere and risk perception, and experiences, knowledges, motivation etc. For this part, the method of questionnaire and statistical analysis are mobilized. The degree of safety commitment of organization members appears relatively high (3.97 in five scale estimation), but there are variations in this results according to socio-demographic characteristics. At the same time, managers and professionals actively participation in the program related to safety than workers in production/sales. The higher income level and career is the more attention to the safety is. Based on this survey, we make an rough suggestion of several tasks to the policy -makers: improvement of communication on the risk and safety is required and in particular, the workers in the relatively low level in production/sales. The education system about safety which is, with one-side, provided by government or managers turns out to be inefficient. Rather, small group performance of the organizational members which they participate in the communication with interaction in the various discourse are able to provoke the safety mood in workplace.

The individual rotten water purification tank recently discharges wastewater and sewage through the outlet without purification ability. The outlet water and affiliated water purification tank with microorganism cultivator tank cultivates microorganism and then drops the value BOD, COD of sewage and discharges the quality of water into the outlet. The blower and water pump operating continuously prompts the waste of energy and deterioration of equipment. Each room of deposition tank, foaming tank, microorganism cultivator tank is equipment with the sludge detection senses so it can detect the density of each room. The power-drive plant of the blower and water pump which ate the system cultivating the microorganism must be made as fuzzy controlization (If the sludge amount of each room become higher, the rate of operation of blower and water pump must heighten, on the contrary, in case of row sludge amount, the total handling amount and microorganism handling amount of each room of control. Tank reducing the rate of operation must be DB. At present, the blower amount in proportion to the sludge and oxygen demanding amount has to control. Each mom must be checked outlet level of the outlet, also each room must flow backward discharge materials, and must operate feed-back control until we want to be come as a below value of BOD/COD(10PPM ; KS).

Therefore, it is expected to improve the efficiency of business processes in the production and safety when we use this system.

This paper deals with Activity Analysis Method that is important procedure in Activity Based Costing System Implementation. There are many existing Activity Analysis Method, for example Interview, Questionnaire, Specialist Discussion and Work Measurement. Activity Analysis Data gained through this method has high reliability but this method bring about high cost. In case that certain company needs a strategic costing system, Activity Analysis Method which has high reliability will be need. But, if companies want the costing system as a internal decision making tool only, they need to design the ABC system fast and cheaply. This paper explains that Activity Analysis using existing finn material is good alternatives. So, this paper show the feasibility of Activity Analysis using existing firm material with comparing between job description, job specification information and Activity Analysis information.

지금까지 인간 감성의 측정은 대부분 제한된 실험실에서 실시되었다. 보다 자연스러운 동적인 환경에서 인간의 감성을 자율신경계의 반응을 통해 추출하고자 본 연구를 수행하였다. 쾌 또는 불쾌한 도로의 시각 환경이 긍정 및 부정 시각으로 제시되었고, 아스팔트, 시멘트, 비포장 도로 등의 도로 굴곡 변화가 또 다른 쾌/불쾌 관련 감성 자극으로 제시되었다. 건강한 5명의 피험자는 실험을 위해 차량 내부에서 도로의 시각 환경을 관찰하게 하였고, 세 가지 굴곡이 다른 도로를 주행하면서 굴곡 변화에 따른 감성을 느끼게 하였다. 심박 변화율, 피부 저항, 피부온도 등의 생리 신호를 측정하였고 주관적 평가와 비교 분석하였다. 피험자가 긍정 시각 장면에 비해 부정 시각 장면을 보았을 때 또한 도로 굴곡의 변화가 클수록 평균 R-R 간격과 피부온도의 감소율은 컸고 피부 전도도는 증가하였다. 본 연구로부터 동적 환경에서 긍정 감성 자극에 비해 부정 감성 자극이 주어 졌을 때 교감 신경계의 활성화가 보다 증가함을 관찰할 수 있었다.

본 연구의 목적은 운전 상황과 도로 상황에 따른 자율신경계의 반응을 측정하는 것이다. 지금까지의 생리 신호는 대부분 제한된 실험실에서 측정되었고, 이 결과들은 자연스러운 상황에 측정된 데이터와는 차이가 있을 것이다. 그러므로 보다 동적인 환경에서 인간의 감성을 추출하고자 본 연구를 수행하였다. 건강한 5명의 피험자로부터 심박 변화율, 피부 저항, 피부온도 등의 생리 신호를 측정하였다. 먼저, 정차, 정속 주행, 급출발, 급제동의 운전 상황 변화에 따른 자율신경계의 반응을 측정하였고, 둘째로, 직선 도로와 굴곡이 심한 도로에서 정속 주행을 하면서 생리 신호를 측정하여 도로상황 변화에 따른 자율신경계의 반응을 측정하였다. 정차 및 정속 주행에 비해 급출발, 급제동일 때, 직선도로에 비해 굴곡이 심한 도로에서 주행을 할 때 평균 R-R 간격은 감소하였고, 전력 스펙트럼의 (LF+MF)/HF비는 증가하였고, 피부온도는 감소하였고, 피부저항은 증가하였다. 본 연구로부터, 정차 및 정속 주행에 비해 급출발, 급제동일 때 그리고 직선도로에 비해 굴곡이 심한 도로에서 주행을 할 때 교감신경계의 활성화비가 증가한다는 일치된 경향을 관찰할 수 있었다. 앞으로 피실험자수를 늘려 보다 정확한 통계적 분석을 하고자 한다.
