In order to ensure the flow of goods available and more flexible, reduce labor costs, many factories and industrial zones around the world are gradually moving to use automated solutions. One of them is to use Automated guided vehicles (AGV). Currently, there are a line tracing method as an AGV operating method, and a method of estimating the current position of the AGV and matching with a factory map and knowing the moving direction of the AGV. In this paper, we propose ceiling Light and guided line based moving direction estimation algorithm using multi-camera on the AGV in smart factory that can operate stable AGV by compensating the disadvantages of existing AGV operation method. The proposed algorithm is able to estimate its position and direction using a general - purpose camera instead of a sensor. Based on this, it can correct its movement error and estimate its own movement path.

According to industrial disaster statistics by the Ministry of Labor in 2006, out of 11,688,797 people working at 1,292,696 business places that apply Industrial Disaster Indemnity Act, 89,910 workers were involved in an accident that more than 4 days of medical treatment requires. Among this figure 2,453 people lost their precious lives. "89,910 industrial disaster victims per annum" is showing the safety level of our industrial situation. To prevent such industrial disaster, the most typical and distinctive method is Accident-free Campaign. At the beginning, the movement arose with devotion through out the entire industry. But, the heartbreaking fact is that the fever is getting cool gown as times goes by. Therefore, opportunity for revitalization of this movement is required. The movement should be practically supporting principle of respect for human life and dignity. And it should be established with analysis on industrial disaster and systematize Accident-free Campaign totally in connected research.

Bridges are critical to the civil engineering infrastructure network as they facilitate movement of people, the transportation of goods and services. Given the aging of bridge infrastructure, federal officials mandate visual inspections biennially to identify necessary repair actions which are time, cost, and labor-intensive. Additionally, the expansion joints of bridges are rarely monitored due to cost. However, expansion joints are critical as they absorb movement from thermal effects, loadings strains, impact, abutment settlement, and vehicle motion movement. Thus, the need to monitor bridge expansion joints efficiently, at a low cost, and wirelessly is desired. This paper addresses bridge joint monitoring needs to develop a cost-effective, real-time wireless system that can be validated in a full-scale bridge structure. To this end, a wireless expansion joint monitoring was developed using commercial-off-the-shelf (COTS) sensors. An in-service bridge was selected as a testbed to validate the performance of the developed system compared with traditional displacement sensor, LVDT, temperature and humidity sensors. The short-term monitoring campaign with the wireless sensor system with the internet protocol version 6 over the time slotted channel hopping mode of IEEE 802.15.4e (6TiSCH) network showed reliable results, providing high potential of the developed system for effective joint monitoring at a low cost.

Background: This study intends to evaluate the benefits of the administation of continuous infusion and demand doses of 0.125% ropivacaine compared with 0.125% bupivacaine after addition of fentanyl using patient controlled epidural analgesia (PCEA) for pain control during labor. Methods: Thirty-nine American Society of Anesthesiologists physical status 1 or 2 parturients were randomized by double blind design to receive either 0.125% bupivacaine with fentanyl 1 ug/ml or equivalent concentration of ropivacaine/fentanyl using PCEA; with 6~8 ml/hr basal rate, 3 ml bolus, 5 min lockout, 30 ml/hr dose limit. We assessed analgesia, the amount of study solution used in PCEA, sensory levels, motor block (0~3 scales), side effects and patient satisfaction. A postpartum questionnaire was carried out afterward. Results: There were no differences in visual analogue scores (VAS) for pain, hourly study solution use, sensory levels, side effects and patient satisfaction between groups. However, patients administered ropivacaine/fentanyl had significantly less demand, less administered in PCEA, less numbness and restriction of movement compared with patients in the bupivacaine/fentanyl group. Conclusions: Ropivacaine 0.125% with fentanyl, when administerd epidurally by PCEA for labor analgesia, was equally efficious as bupivaciane 0.125% with fentanyl, having with minimal numbness and restriction of motion.

We, at The Korea Democracy Movement Archives opened temporarily at SungKongHoe University(SKHU), have currently collected about 100,000 recorded materials of democratization movement related with labor, farmer, civilian, human rights, peace, unification, young people, student and women's movements by investigating, collecting and receiving donations from civil organizations and individuals, and about 70,000 data out of this 100,000 data were converted into computer files. The Korea Democracy Movement Archives(temp) at SKHU has a significance in that it is the first archive opened by an organization. Furthermore, the opening of this Archive means the expansion of awareness on recording culture and accumulation of the achievements of the democratization movement in Korea. However, many obstacles still remain in the establishment of this Archive in a full-scale. This article examined many theoretical and realistic obstacles posed to the archivists, who are the professionals responsible for record management, in process of establishing the Archive, and the role and future perspectives of the archivists at The Korea Democracy Movement Archives(temp). The first obstacles in the process of organizing and separating the recorded materials at the Archive is a difficulty in the description of classifying the different movement organizations. The second obstacle is a difficulty in specifically applying the international standard, ISAD(G), of record description in the process of establishing the description items. Through many trials and errors, we need to try to confirm the description befitting. The Korea Democracy Movement Archives through continuous adjustment and complementary measures. The third obstacle is a difficulty in estimating the range and physical and quantitative amount of the recorded materials since the collection of recorded materials is complete. Thus, the answers to these problems lie in continuous efforts to establish a creative classification system befitting the democratization movement in Korea in the process of many trials and errors and endeavor. The evaluation classification done by archivists is a creative act forming record heritage, and archivists need to form record heritage reflecting the evaluation system of a certain period. Moreover, they transmit the shape of the current era in a maximum scale to the future by using the minimum amount of records. An archivist is responsible for two tasks, i.e., preserving a record and making other people to utilize the record by working with record. However, We, at The Korea Democracy Movement Archives(temp), have an additional task of contributing to the democratization movement in korea that has not ended by collecting, preserving and making people to utilize the fragments of memory in the recent history of Korea by establishing the Archives.

대부분의 근대예술영역에서 시도된 자본주의적 저항운동은 예술과 기술의 융합, 즉 상징적 경계의 새로운 형성을 통해 진행되었다. 러스킨과 모리스로 대표되는 이러한 저항운동은 수공예 장인의 부활을 통한 장인적 예술의 복원이 목표였지만 결과적으로 예술의 계급화를 초래하게 되었고 자율적인 노동을 배제하게 되는 탈장인적인 예술이 되었다. 이에 본 연구는 장인적 노동의 복원을 위한 노력으로서 유일하게 기계제대공업이 가져온 조건을 적극 활용하는, 즉 '기술과 예술 그리고 기계와 산업의 융합'을 통해 상징적 경계의 해체와 새로운 융합을 시도하였던 바우하우스에 주목하여 그것의 '행위자들actors'을 중점적으로 살펴보고자 한다. 본 연구에서는 16세기 르네상스 예술부흥운동, 19세기 미술공예운동, 그리고 바우하우스의 예술적 사조가 역사적으로 연계되어 있다는 것을 전제로 <생산으로서의 장인적 예술, 예술소비로서의 민중의 권리, 표현방식으로서의 근대기술>의 교량역할을 수행했던 바우하우스 실천가들과 그들 사이의 협력과 갈등에 대한 고찰을 통해 바우하우스가 디자인 민주주의 이념을 구현하려 하였다는 점을 주장하고 있다. 더 나아가 현대 메타기술의 시대가 디자인과 기술의 융합을 통한 민주주의로의 이행을 추동하고 있어 바우하우스의 '협력과 갈등'그리고 '위기와 해체'로부터 반면교사해야 함을 보여주고 있다.

기업이 살아남기 위해서는 이윤을 추구해야 하는 것 뿐 만 아니라 사회적 책임이 요구된다. 이러한 사회적 책임은 비단 기업 뿐 만이 아니라 기업의 하위시스템인 노동조합에도 사회적 책임이 요구된다. 그러나 이러한 노조의 사회적 책임(Union Social Responsibility, 이하 USR)에 대한 실행사례와 이에 대한 연구는 미미한 것이 사실이다. 노동조합이 지속적으로 생존하고 그 역할을 다하기 위해서는 조합원들만의 기대를 충족시키는 것은 기본이고, 비노조원, 지역사회 등 노동조합과 관련된 이해관계자들의 기대를 충족시켜야 한다. 이에 본 연구에서는 노조의 사회적 책임에 대해 우리나라에서는 선도적이라 할 수 있는 LG전자 노동조합의 USR사례를 살펴보았다. LG전자 노동조합은 2010년 USR을 도입하면서 노동운동의 변화를 추진하였고, 지역사회와 취약계층에 대한 봉사와 파업 자제를 통한 산업평화 확립, 환경보호 등과 같은 내용의 USR을 실천하였으며, 국내 사업장 뿐 만 아니라, LG그룹 내부 및 해외사업장에도 이를 전파하였다. 본 연구에서는 이러한 LG전자 노동조합의 사례를 통해 사회적 존재로서의 노동조합의 새로운 길에 대해 모색하고자 한다.

This paper investigates the development and aesthetics of Korean political theatre from its quickening period 1920s to democratization era 1990s. Political theatre before 90s developed an antithesis resistant movement toward Korean modern history that had been scattered with suppressing political circumstances such as colonial era and dictatorial government, the movement has powerful activity and social influences. Just like the 20 century political theatre had been quickened under the influence of Marxism at Russia and Germany in 1920s, Korea's political theatre began in socialism theatre movement form around the same time. Proletarian theatre groups had been founded in Japan and Korea, and developed into practical movement with organized connection. However, the political theatre movement in Japanese colonial era was an empty vessel makes great sound but not much accomplishments. Most performance had been canceled or disapproved by suppression or censorship of the Japanese Empire. The political theatre in liberation era was the left drama inherited from Proletarian theatre of the colonial era. Korean Theatre alliance took lead the theatrical world unfold activities based on theatre popularization theory such as 'culture activists' taking a jump up the line and 'independent theatre' peeping into production spot as well as the important event, Independence Movement Day Memorial tournament theatre. Since 1947, US army military government in Korea strongly oppressed the left performances to stop and theatrical movement was ended due to many left theatrical people defection to North Korea. The political theatre in 1960s to 70s the Park regime, developed in dramatically different ways according to orthodox group and group out of power. The political theatre of institutional system handled judgment on sterile people and had indirect political theatre from that took history material and allegory technique because of censorship. In political theatre out of institution, it started outdoor theatre that has modernized traditional performance style and established deep relationship with labor spot and culture movement organizations. Madangguek(Outdoor theatre) is 'Attentive political theatre', satirizing and offending the political and social inconsistencies such as the dictatorial government's oppression and unbalanced distribution, alienation of general people, and foreign powers' pillage sharply as well as laughing at the Establishment with negative characters. The political theatre in 1980s is divided into two categories; political theatre of institutional system and Madangguek. Institutional Political theatre mainly performed in Korea Theatre Festival and the theatre group 'Yeonwoo-Moudae' led political theatre as private theatre company. Madangguek developed into an outdoor theatrical for indoor theatre capturing postcolonial historical view. Yeonwoo-Moudae theatre company produced representative political plays at 80s such as The chronicles of Han's, Birds fly away too, and so on by combining freewheeling play spirit of Madangguek and epic theatre. Political theatre was all the rage since the age of democratization started in 1987 and political materials has been freed from ban. However, political theatre was slowly declined as real socialism was crumbling and postmodernism is becoming the spirit of the times. After 90s, there are no more plays of ideology and propaganda that aim at politicization of theatre. As the age rapidly entered into the age of deideology, political theatre discourse also changed greatly. The concept 'the political' became influential as a new political possibility that stands up to neoliberalism system in the evasion of politics. Rather than reenact political issues, it experiments new political theatre that involves something political by deconstructing and reassigning audience's political sense with provocative forms, staging others and drawing discussion about it.

Enterprises play an increasingly important role in economic development in each country. Effective businesses will make the economies of countries also become efficient and develop. Enterprises play a role in creating jobs, improving labor productivity, and connecting foreign trade and import-export activities. The study aims to evaluate the factors affecting the profitability of small and medium enterprises in Hanoi by using a study of 210 enterprises in the area as well as advanced econometric regression analysis. The research results show that firm size and human capital have no impact on business performance. However, older firms are likely to have higher firm performance, and conversely, younger firms have lower firm performance. The research also confirms that the growth of businesses often has higher firm performance than low-growth ones. Furthermore, a firm with greater value is also more likely to stimulate business performance than lower its value, and this effect is the largest among the analyzed factors. Finally, the study also has some recommendations for the Vietnamese government to develop small and medium enterprises. Specifically, the government needs to create an open mechanism for the start-up movement and create a favorable financial mechanism for small and medium-sized enterprises to be able to access.

직무만족이 노조참여를 촉진하는가 아니면 줄일 것인가에 대해서는 오랜 논쟁이 있었다. 본 연구는 직무만족과 노조참여와의 관계에서 노조수단성의 조절효과를 분석하였다. 22개 사업장 826명의 종업원을 대상으로 실증적 조사를 실시하였다. 실증연구의 결과 직무만족과 노조참여 사이에 정(+)의 효과와 부(-)의 효과가 동시에 발견되었다. 직무만족의 노조참여에 대한 직접적인 영향은 정(+)의 효과가 나타났으나, 직무만족과 노조수단성의 상호작용을 함께 고려하였을 때는 직무만족은 노조참여에 부(-)의 효과가 발견되었다. 이러한 결과는 직무만족이 노조참여에 대한 직접적인 관계는 노조참여에 대한 불만관점을 지지해주고 있으며, 직무만족과 노조수단성의 상호작용 효과는 효용관점을 지지해준다. 본 연구는 구성원의 직무만족이 독자적으로 노조참여에 영향을 미치는 경우 보다는 직무만족과 노조수단성과 유기적인 상호 연계가 이루어질 때 노조참여 효과가 더욱 강화될 수 있음을 시사하고 있다. 따라서 실무적 측면에서 노조가 노조활성화를 기대한다면 근로자의 근로조건과 거리가 먼 정치투쟁적 노동운동보다 노조원의 기대를 충족해 줄 수 있는 다양한 서비스에 초점을 맞춘 노동운동이 중요하다는 것을 시사한다. 이를 통해 우리나라 노동조합이 나아갈 방향을 제시해준다.
