This article advocates for a Mode 3 science policy. Compared to the university research-based Mode 1 knowledge production system and the knowledge application-centric Mode 2 innovation system, Mode 3 can be defined as a system that integrates both Mode 1 and Mode 2-type knowledge production models. In this article, based on the major characteristics of the Mode 3 scientific knowledge production system, I agree with the advocates of Mode 3 that constructing a knowledge society requires an inclusive form of knowledge production and innovation system through the democratization of knowledge production as well as the promotion of social values. Moreover, the mechanisms for creating accountable innovation in the Mode 3 system should be given more attention from the science research and policy communities to make public policy for scientific and technological innovation more reflective of social changes. Similar to the ways that the Mode 1 and Mode 2 scientific knowledge production approaches have influenced the development of science policy models, the Mode 3 scientific knowledge production approach, or Mode 3 science, also has the potential to shape a new science policy model. I will refer to this as Mode 3 science policy. In an effort to conceptualize the democracy- and society-centric Mode 3 science policy model, I will articulate science policy strategies in four science policy domains in South Korea from the context of the Mode 3 science approach. These include (1) evaluation of publicly-funded research activities, (2) valorization of scientific knowledge (that is, enhancement of the value of scientific knowledge through governmental action), (3) development of a science policy decision-making support system, and (4) anticipatory foresight of science, technology and society. When adopting and implementing a Mode 3 science framework, one progressive change is to increase socially desirable innovation such as responsible innovation.

The purpose of this study is to investigate a causal relationship between the mode of production and change of rural society. While dominant theories of social change have stressed variation of contingencies and periodical contexts, this theoretical paper drives a new insight paralleling diverse theoretical arguments of each mode of production with rural and urban changes. Investigating the drifts of intellectual ideologies of the mode of production, we get through diverse paradigm shifts of the production accumulation and its trigger effects on rural change. More specifically, the present study investigates change of rural society by way of investigating such fluctuations of societal changes as ancient society, slavery society, feudal society, industrial society, post-industrial society, and information society. We find that transportation and communication technologies have had a key role in the changes, however, the effects of the technologies on social changes have been different between rural- and urban-society. While we take it for granted that flexible accumulation in post-industrial society and time-space compression and informatization in information society will reduce developmental gap between rural- and urban-society, we also found that there have been big differences of actual application of the technologies between theory and reality in each era of mode of production.

The variations of performance and metabolites at an early stage were investigated for the successful start-up technology in continuous fermentative hydrogen production. Unsuccessful start-up was observed when the operation mode was changed from batch to continuous mode after the yield was reached to 0.5 mol $H_2$/mol $hexose_{added}$ by batch mode. $H_2$ production continued till 12 hours accompanied by butyrate production, but did not last with propionate production increase. It was suspected that the failure was due to the regrowth of propionic acid bacteria during batch mode which were inhibited by heat-shock but not completely killed. Thus, successful start-up was tried by early switchover from batch to continuous operation; continuous operation was started after the $H_2$ yield was reached to 0.2 mol $H_2$/mol $hexose_{added}$ by batch mode. Although $H_2$ production rate decreased at an early stage, stable $H_2$ yield of 0.8 mol $H_2$/mol $hexose_{added}$ was achieved after 10 days by lowering down propionate production. And it was also concluded that the reason for $H_2$ production decrease at an early stage was due to alcohol production by self detoxification mechanism against VFAs accumulation.

The current panels for liquid crystal display (LCD) TV sets are all characterized by pins placed on two sides. To manufacture one type of panel, a dedicated mask is needed, and the production line should be started once. Moreover, the whole panel needs to be removed if a dead pixel is found. If the panel, however, will first be fabricated with pins placed on four sides and then divided by a cross-cut into four equal-sized panels with pins placed on two sides, one set of masks can be used to manufacture two types of LCD panels, which was referred to by the authors as dual mode. In this paper, the concept of the dual mode and its differences from the conventional way of producing panels are introduced. Its advantages in boosting production efficiency, improving the product's good rate, and lowering the production cost are also described based on case studies. Of particular importance is the fact that the dual mode is very suitable for the trial production of very-large-area LCD TV sets.

Focusing on Hwaseokjeong in Paju, the work seeks to clarify the social production of Nujeong (樓亭: Korean traditional pavilions) space, which took place over the 1960s and 70s, and its cultural-political implications. To make the effort as such meaningful, a theoretical framework based not merely on the thesis of 'social production of space' advocated by Henri Lefebvre but especially on some discussions related to 'state production of space' is prepared, according to which Hwaseokjeong is analyzed and explained. As a consequence, two principal arguments are put forward: one is that Hwaseokjeong was a social space which had been built and constructed in accordance with the unique mode of production dominating Korean society at that time called 'the state mode of production (le mode de production étatique)'; the other is that what lies beneath the denotation of a 'social space of tradition restoration' that Hwaseokjeong appears to carry is in fact the connotation of 'infiltration of anti-communist ideology'. All of these claims are once again supported both by examining Roland Barthes's semiology and mythologies and by considering Hwaseokjeong's P yeonaek (扁額: a plaque or framed text) as 'the practice of naming power through Jesa (題詞: inscribing dedications)'. While providing a succinct summary, the paper finally evaluates what 'social production of space' implies to social practices of architecture and related criticisms by taking into account the relationship between visibility and readability of space including buildings.

This paper considers a scheduling problem to minimize the sum of the associated scheduling (production/delivery times) cost and the delivery cost for an integrated system of a single production machine and various transportation vehicles with transportation mode selection allowed. Each transportation mode is provided with a fixed number of vehicles at the associated delivery time and cost. The proposed problem is characterized as being NP-hard. Some solution properties are also characterized. Therewith, three heuristic algorithms (called SPT-based, LWF-based and WSPT-based heuristic) and a branch-and-bound algorithm are derived. In order to evaluate the effectiveness and efficiency of the proposed algorithms, computational experiments are made with some numerical instances.

본 논문은 뱀파이어라는 널리 퍼진 이미지가 나타내는 문화적 기호가 일본적 혹은 동아시아적인 생산양식 아래서 보여주는 모습과 가능성을 보는데 있다. 서구문화를 일찍이 토착화해 온 일본에서 뱀파이어의 이미지를 어떻게 토착화하여 해석하고 새로이 제시하는가를 일본 만화를 통해 알아보고 이를 통해 우리 문화에 변형과 가능성을 타진하는데 본 논문의 목적이 있다. 아시아적 생산양식은 아시아 여러 지역에서의 사회 및 경제 발전을 특정 짓는 생산양식을 말하며, 마르크스는 "대략적으로 말해서 아시아적 고대적 봉건적 및 근대 부르주아적 생산양식이 경제적 사회구성의 여러 시기로 표시될 수 있다"고 말하였다. 일본근대역사가 가지는 특이성은 아마도 왕-쇼군-사무라이-농노를 잇는 지역기반의 봉건사회에서 메이지유신을 통해 전면적인 서구적인 사회로의 변화를 들 수 있다. 하지만, 우리는 이 서구화가 과연 민주화나 봉건적인 사회구조를 전면적으로 변형시켰는가는 조금 더 깊이 있는 관찰이 필요하고 이에 드러나는 갈등을 <피안도>를 통해 보고자 한다. 일반적인 이미지로, 뱀파이어는 신의 저주를 받아 태양빛을 볼 수 없고, 인간의 생물학적인 생명현상을 보이지는 않지만, 인간의 피를 빨아먹어야 '활동'을 유지하는 존재를 지칭한다. 이들은 보통 인간보다 육체적이고 정신적으로 강하며, 유혹하는 능력과 박쥐로 변하는 능력을 지닌다고 한다. <피안도>가 가지는 동아시아적 뱀파이어 코드가 가지는 특색 있는 독자성과 의의를 알아본다. 마지막으로 <피안도>가 지니는 동아시아적 생산양식의 모습과 한국적 현실 그리고 한국적 뱀파이어 문화에 대하여 모색하며 본 논문을 마치고자 한다.

Rapid globalization of production and marketing functions makes choice of international transportation mode of great importance. In this paper, transportation mode is characterized by two factors, mean and variability of transportation lead time. We developed a simple mathematical model to estimate the relative impact of mean lead time, lead time variance and demand variance on the required average inventory level under specified service rates.

In this study, we have performed the Cone Calorimeter test and Smoke density test in accordance with ISO 5660-1 and ASTM E662 respectively to check the smoke production characteristics of rubber flooring materials for railway vehicle. Early in the ASTM E662 test, more smoke was produced in the flame mode test than non-flame mode test, but later more smoke was produced in non-flame mode test. The correlation($R^2$) between TSR(Total Smoke Release) by ISO 5660-1 and Ds(Specific Optical Density) by ASTM E662 Flame mode was 0.782. The $R^2$ between TSR by ISO 5660-1 and Ds by ASTM E662 Non-flame was 0.930.

This paper investigates the characteristics of interlaminar fracture toughness of foam core sandwich structures under opening mode by using the double cantilever beam (DCB) specimens which are Carbon/Epoxy and foam core composites. Instead of using a DCB specimen of symmetric geometry, a non-symmetric DCB specimen was used to calculate the interlaminar fracture toughness. Three approaches for calculating the energy release rate(G$\sub$IC/) were used and fracture toughness of foam core sandwich structures made by autoclave, vacuum bagging and hotpress were compared. Experiment, analysis using nonlinear beam bending theory, and numerical work by FEM methods were performed. Bonding surface compensation and equivalent moment of inertia were used to calculate the energy release rate in nonlinear analytical work. Conclusions of experimental, nonlinear analytical and FEM methods were compared. It is, also, shown that the vacuum bagging forming can substitute the method of autoclave without serious loss of Mode I energy release rate(G$\sub$I/).
