In this paper, we review relevant technologies of MR (Mixed Reality) and show important components of perspective that can overcome technical limitations of the current MR. An MR technology combines real and virtual objects in a real environment, and runs interactive in real time, and is regarded as an emerging technology in a large part of the future of IT (Information Technology). We've grouped the major obstacles limiting the wider use of MR technologies into three themes: technological limitations (i,e., tracking, rendering, authoring, and registration), user interface limitations(i.e. UI metaphor for MR interaction), and social acceptance Issues.

The purpose of this study was to conduct importance and performance analysis of sanitation management in workers at small and medium foodservice industries using HACCP prerequisites. Questionnaires were distributed to 500 small and medium foodservice industry workers in Seoul Gyeonggi province, and a total of 458 responses were used for analysis. Factors with relatively low comparison degree were as follows. 'Handwashing and clean uniform of employee in the workplace', 'regular checking and managing of trapped vermin and rodents', 'checking stocked raw materials', 'recording and filing the results of improved food safety factors', and 'regular cleaning and sterilizing of monitoring tools' factors must be improved along with their performance levels through sanitation education. According to the IPA results, among the 15 HACCP prerequisite factors with high importance but low performance were '2. Regular checking and managing of trapped vermin and rodents', '4. Handwashing and clean uniform of employee in the workplace', '14. Preventing food cross-contamination'. Furthermore, the small and medium foodservice industry IPA with high importance but low performance were 'Regular checking and managing of trapped vermin and rodents', 'Handwashing and clean uniform of employee in the workplace', and 'Preventing food cross-contamination' for the small foodservice industry, along with 'Vermin and rodents control' and 'Recording and filing the results of improved food safety factors' for the medium foodservice industry. Thus, there is a need for reinforced hygiene education through case studies on actual food service establishments to fulfill sanitation guidelines and set amended guides for much-needed items for small and mid-sized food service.

This study was conducted to provide the basic data about the health effects of pesticide exposure among farmers for agricultural health study. We analyzed 412 self-administered questionnaires collected from the male farmers who spray pesticides in Kyoung-ju area, Korea. Survey questions were about chronic symptoms, acute symptoms while pesticide spraying, pesticide intoxication accident, safety rules, protective equipments etc. The correlations among the variables related to pesticide exposure and the factors in acute pesticide poisoning and chronic symptoms of farmers were also analyzed. For chronic symptoms, the prevalence of 'tiredness and languor', 'lumbago', 'nocturia', 'shoulder pain', 'numbness', and, for acute symptoms while pesticide spraying, the experience rate of 'itching sense of skin', 'dizziness/headache', 'fatigue', 'eye glaring' were high compared with other symptoms. For 'experience of intoxication accident by pesticide in family', 7.1% of the subjects experienced the accident and the causes were pesticide spraying, food contamination by pesticide, suicide etc. Among safety rules, 'take a bath after spraying', 'change clothes after spraying' were kept relatively well, and, for protective equipments, hat, boots, mask, gloves, protective clothes(lower) were put on relatively well. The factors associated with acute pesticide poisoning were the extent of keeping safety rules, spraying time, orchard cultivation, agricultural area and spraying days per year etc. And the factors associated with chronic symptoms were acute symptoms while pesticide spraying, agricultural area, farming career, extent of keeping safety rules, extent of agricultural work and the pesticide exposure index etc. From these results, it is suggested that to reduce the health effects by pesticide exposure among farmers, the education to promote to keep safety rules and wear protective equipments, and information services should be recommended. And further studies on the long term health effects of pesticide exposure among farmers are required.

세계화, 국제화, 개방화 시대에 살고 있는 우리가 통과의례나 전통 명절과 같은 특별한 행사에 의례복으로 한복을 애용하는 것은 한복이 한국의 문화적 이미지를 강하게 간직하고 있는 한국적 조형물 중의 하나이기 때문이다. 더우기 의례복은 특별한 행사 자체를 위해 착용되었던 만큼 당시대의 내 적 가치를 가장 현저하게 표출하고 있는 복식으로 인정 할 수 있기 때문이다. 본 연구의 목적은 시대 적으로 현대 전통 한복의 기본 형 식을 제공한 조선시대와 그 이후의 복식 중에서 특히 분명한 착용동기와 목적, 복식을 통해 나타내고자 하는 상징성 등을 함축하고 있는 아동용 의례복을 대상으로 복식의 형태, 색채, 문양, 소재 등의 조형 요소를 고찰하는 것이다. 또한 양식적 특성을 살펴보고, 그러한 조형적 특성을 형성시킨 당시대의 사상적 가치를 추론해 보는 것이다. 구체 적인 연구 방법은 먼저 관련된 문헌 고찰을 통한 이론적 배경을 토대로 하여 아동용 의례복의 범주를 설정하고 현재 보전중인 실물과 또는 사진, 풍속화에 나타난 복식 자료들을 수집하였다. 그리고 당시대의 사상적 배경에 대한 고찰을 병행하여 이들에 내재된 문화적 가치를 추출해 보았다. 연구 결과 양식적 특징으로는 남아의 두루마기나 전복 그리고 쓰개류 등에서 기능성을 고려한 변형적 양식이 나타나고 있었다. 색채 역시 음양 보색이나, 오행색을 바탕으로 한 기본색의 구성 이외 에도 소매나 섶에 응용된 색의 배열이나 맞깃 전복의 깃에 나타난 색의 조화는 다양한 색의 조형미를 표현하고 있었다. 특히 색동 등에 나타난 오행색의 배열, 안감과 겉감, 상의와 하의, 외의와 내의에 사용된 색의 조화는 미의식에 관한 문화적 가치를 추론해 볼 수 있다. 더우기 장식 표현에 주로 쓰인 자연물 문양이나 글자 문양은 당시의 지배 사상이 지향하는 덕목 이외에도 전통적으로 내재된 수명과 복록, 부귀와 영화에 대한 내적 가치들을 반영하는 조형적 상징들이라 할 수 있다. 소재는 비교적 계절을 고려하여 사용되고 있었지만 의례적 성격을 지닌 외의나 쓰개류의 경우 계절적 구분을 고려하지 않은 경우도 많이 나타나고 있었다. 장신구의 경우는 많이 사용되는 것은 아니나 역시 상징적 인 가치를 표현하는 실물들을 미적으로 재구성한 사례들이 나타나고 있었다. 이상의 연구를 통해 아동용 전통 의례복은 형태, 색채, 문양, 소재, 장신구 등에서 양식의 다양성과 변형들을 알 수 있었다. 또한 적극적인 내적 가치의 상징들을 복식을 통해 표현하고 있었음을 알 수 있었다. 현대 복식의 디자인에 있어 아동용 의례복에 나타난 창조적인 양식의 변형과 다양성 그리고 복식을 통한 내적 가치의 반영 등이 현대 사회와 조화를 이룬 실질적인 복식 디자인 제시 및 창작에 작은 영감으로 작용하길 바란다.

Purpose: The purpose of this study is to develop a deep learning-based personal protective equipment detection model for disaster prevention at construction sites, and to apply it to actual construction sites and to analyze the results. Method: In the method of conducting this study, the dataset on the real environment was constructed and the developed personal protective equipment(PPE) detection model was applied. The PPE detection model mainly consists of worker detection and PPE classification model.The worker detection model uses a deep learning-based algorithm to build a dataset obtained from the actual field to learn and detect workers, and the PPE classification model applies the PPE detection algorithm learned from the worker detection area extracted from the work detection model. For verification of the proposed model, experimental results were derived from data obtained from three construction sites. Results: The application of the PPE recognition model to construction site brings up the problems related to mis-recognition and non-recognition. Conclusions: The analysis outcomes were produced to apply the object recognition technology to a construction site, and the need for follow-up research was suggested through representative cases of worker recognition and non-recognition, and mis-recognition of personal protective equipment.

This paper, a basic study on the restoration of arrow quivers during the Three Kingdoms Period, aimed to contribute details to the existing plan to restore the arrow quivers. The arrow quivers of the Three Kingdoms Period consist of a pouch for holding arrows and a backpiece. However, the two parts do not remain, and only metal parts have been excavated. The excavated arrow quivers were classified into three types for restoration. Centered on the pouch, the quivers were classified into type 1 made up of a W-shaped part and ㄷ-shaped part, and type 2 with only the band-shaped piece identified. Type 3 is similar to type 2, but it is assumed to be a separate type where an iron band extending from the hanging piece(吊手金具) is connected to a band-shaped piece. Before proposing a restoration plan for the three types of arrow quivers, the location of the hanging piece (吊手金具) and the observation of organic matter were reflected. In addition, such details as the location of the hanging piece (吊手金具), which cannot be identified by the excavation status alone, were derived from the ways of wearing the arrow quivers observed in the Joseon Dynasty, Shosoin (正倉院), and Haniwa (埴輪) in Japan. Referring to the existing record on the transformation of arrow quivers based on the hanging piece (吊手金具), the arrow quivers change from type 1 to types 2 and 3 in this paper. However, some of types 2 and 3 maintain the ways of wearing of type 1, and there were cases where the old-fashioned parts were kept. In particular, in Haman (咸安), it was confirmed that the typical type 1 was buried up until late periods.

The G20 summit is the premier forum for international economic cooperation and it will be held in Seoul in November 2010. However, protests are expected during the Seoul summit, as a part of the deepening global war against capitalism. The Korean Police need to deal with these protests effectively in order to provide security to the participating leaders and make the meeting run on wheel as planned. The current study attempts to analyze the death of Ian Tomlinson who died in the context of a heavily policed protest during 2009 G20 London summit. There are number of unique features regarding this incident, such as the public scrutiny of police conduct through video footage, the police use of excessive force, and the process to hold the police to account for misconduct. This incident caused serious damages to the public's faith in the British police. Based on the analysis, this study found that during the G20 London summit British police had the problems such as the lack of the clear standards on the use of force, improper training in the use of force, poor communications with the media and protesters, inappropriate use of the close containment tactic, and the failure to display police identification. Therefore, this study suggests the inducement of peaceful protests, the adoption of a set of standards on the use of force, public order training that is more directed and more relevant to the public order challenges facing the Korean police, improvement of the communication with the media and protesters, enhancement of individual officer's accountability as public order policing strategies for G20 Seoul summit meeting. However, the most fundamental principle is that Korean police must place a high value on tolerance and winning the consent of the public.

The purpose of this study is to grasp the overall policy decision system of sex crime prevention policy and analyze the interaction and pattern of actors in policy formation process. This is a useful way to identify the causes and ways to improve the policy if the sex crime prevention policy fails. As a research method, we used a model of advocacy through case analysis and language network analysis. In the external environment, low reporting of sex offenses, technical improvement and supplement for preventive management, consciousness of victims of sexual crimes, amendment of legislation, and support of the president. The conflicts between the advocacy coalition opposed the strong regulation, the prevention of recidivism, the expansion of the range of objects to be worn, the temporary effect of the system and the retrospective of the bill. As a problem-solving strategy, it was confirmed that the opposing positions of pros and cons of lack of manpower and negligence of management through the extension of the system were acutely opposed. In the context of media reports, this tendency is more likely to be understood as the concern of prevention and management at the central government level to prevent sex crimes. Therefore, although the methods of prevention of sex crimes have been insufficient in the past, it is hoped that this study will be helpful in breaking the link of negative policy vicious cycle.

Construction accidents occur due to a number of reasons-worker carelessness, non-adoption of safety equipment, and failure to comply with safety rules are some examples. Because much construction work is done outdoors, weather conditions can also be a factor in accidents. Past construction accident data are useful for accident prevention, but since construction accident data are often in a text format consisting of natural language, extracting construction hazards from construction accident data can take a lot of time and that entails extra cost. Therefore, in this study, we extracted construction hazards from 2,026 domestic construction accident reports using text mining and performed a seasonal analysis of construction hazards through frequency analysis and centrality analysis. Of the 254 construction hazards defined by Korea's Ministry of Land, Infrastructure, and Transport, we extracted 51 risk factors from the construction accident data. The results showed that a significant hazard was "Formwork" in spring and autumn, "Scaffold" in summer, and "Crane" in winter. The proposed method would enable construction safety managers to prepare better safety measures against outdoor construction accidents according to weather, season, and climate.

The purpose of this paper is to develop usability evaluation tool for wearable computer. In this paper, we propose evaluation factor and object through context evaluation in the real environment. The basic idea of this process is to know the thought from wearable user. Also, we gathered the opinion from expert group. As a result, we adopted evaluation question categories. By examining some empirical data which is obtained from observation and wearability evaluation, we conclude usability evaluation of wearable computer, including smart clothing. The design process in creating a successful wearable usability is no longer about providing technical success, rather about creating a optimal user experience.
