Carbon Fiber Re-enforced Polymer (CFRP) has replaced steel, especially for mobile devices. As CFRP is stiff and light-weight, it has been applied to airplane, sport car, golf clubs, semiconductor transporter, satellites, etc. In the telescope, the plastic material was introduced to the supporting tubes or rods connecting the primary mirror assembly and the secondary mirror structure. Nowadays, even the mirror itself is produced by CFRP. In this poster, material properties and production of CFRP telescopes are presented, and pros and cons are discussed.

34 packaged meal (Dosirak) manufacturing establishments were assessed in terms of working environment, production and transportation practices. Questionnaires and facility check-lists were developed. Most establishments were small in business, and production personnel as well as production facilities were insufficient compared with production capacity of establishments. Mean production capacity for packaged meals in terms of optimum and maximum levels were 6,500 and 15,166 meals in large sized establishments; 2,662 and 8,301 in medium; and 2,112, and 4,733 in small respectively. Those figures indicate potentially hazardous practices in production especially in small and medium sized establishments. Most meals were produced to order. Transportation facility and kitchen space were assessed as insufficient.

Green Frame is a method for Rahmen structure construction composed of composite PC members. The composite PC members of Green Frame which are based on in-situ production can reduce the construction cost and are more likely to secure quality when compared to production in factories. Previous studies developed forms for in-situ production of Green Frame composite PC members and proposed algorithms to arrange them on site. However, it requires not only their arrangement, but also calculation of an accurate production period to produce the required PC members in a limited space and supply them in a timely manner. In particular, it is necessary to clearly define the properties of detailed processes for in-situ production of PC members and to calculate the time required for respective process. To do so, this study is a basic research on calculating the time for in-situ production using a linear scheduling method.

In the trend of globalization and location transfer of existing production bases is still characterized by an extremely unstable status between different countries and different regions. The results are negative impacts on cost, quality and speed of project implementation, especially automobile industry which is one of the most complex manufacturing sectors. In order to overcome problems from Global Standardization of Production Line and its Localization, it is highly required comprehensive coordination among design of production equipment, production technology, space and interfaces. It is necessary to set up standard of production equipment and building for parallel progress, in order to complete production line in shortest time for launching product. In addition, this standard should keep flexibility with consideration of local situation which means "Glocalization."

As the existing paradigm of consumption has changed, companies have been actively engaged in targeting culture-oriented emotion, creating added values through appealing to customers' emotion and improving the values of culture and art. Each company has created differentiated space and inner space to lead trends, and has provided space for various experiences as an innovative marketing area to attract customers and promote consumption. In this aspect, we should focus on space marketing which considers cultural background or emotion as a main target Therefore, this study selected a cultural program as a strategic means to identify space marketing in terms of experience. The study speculated marketing in terms of space experience and analysed space for cultural programs with differentiated experiences in order to use the results as basic data for identifying the marketing values of the cultural programs and their uses. The results of the study are presented as follows: when space experience is a factor of marketing and the cultural program is a tactic in terms of marketing, their specific relations are speculated through a certain module. The order of using the cultural program for space experience, features of space representation and tactics for experience were different and the strategies evoked very complicated and mixed experiences.

This study seeks to offer practical suggestions for manufacturing jacket lining patterns through research on menswear brands. A researcher conducted interviews with a survey instrument targeting 12 menswear brands. To analyze the data, descriptive statistics were obtained using SPSS 18.0. The main findings were as follows. First, regarding lining production, most menswear brands were found to provide jacket lining patterns to their subcontractors, and pattern makers were found to design lining patterns based on their own know-how. The most important factor in the production of jacket lining patterns is whether linings are cut more than once during the sewing process. For suit jackets, linings are cut more than once, and for casual jackets, linings are cut once. Second, with regard to jacket production for different jacket styles, most menswear brands were found to use patterns that include seam allowance. Partial linings showed differences in terms of the methods used to sew edges and attach linings to the outer shell. Third, extra space in jacket lining patterns varied according to style. Jacket lining patterns for suit jackets and casual jackets showed differences in extra space in the following areas: the parts that cover the chest(suit jacket linings: 5.6cm, casual jacket linings: 2.4cm), the parts that cover the waist(suit jacket linings: 3.8cm, casual jacket linings: 1.3cm), hem(suit jacket linings: 2.7cm, casual jacket linings: 1.3cm), and bicep(suit jacket linings: 2.7cm, casual jacket linings: 1.1cm). However, extra space in the sleeve hems was identical for the two styles(suit jacket linings: 0.1cm, casual jacket linings: 0.1cm). Therefore, this research suggests that clothing manufacturers design linings in accordance with the jacket lining production style.

The purpose of this study is to analyze the returns to scale by estimating the bigeye tuna production function of Korean distant longline fisheries in WCFPC waters. In the analysis, number of crews, vessel tonnage, number of hooks, and bigeye tuna biomass are used as input variables and the catch amount of bigeye tuna is used as an output variable in the Cobb-Douglas production function. Prior to the function estimation, the biomass of bigeye tuna was estimated by the Bayesian state-space model. Results showed that the fixed effect model was selected based on the hausman test, and vessel tonnage, hooks, and biomass would have direct effects on the catch amount. In addition, it was shown that the bigeye tuna distant longline fisheries in WCFPC water would have increasing returns to scale.

It is a difficult task to estimate parameters in even a simple stock assessment model such as a surplus production model, using only data about temporal catch-per-unit-effort (CPUE) (or survey index) and fishery yields. Such difficulty is exacerbated when time-varying parameters are treated as random effects (aka state variables). To overcome the difficulty, previous studies incorporated somewhat subjective assumptions (e.g., B₁=K) or informative priors of parameters. A key is how to build an objective joint prior of parameters, reducing subjectivity. Given the limited data on temporal CPUEs and fishery yields from 1999-2020 for common squid Todarodes pacificus, we built a joint prior of only two parameters, intrinsic growth rate (r) and carrying capacity (K), based on the resilience level of the population (Froese et al., 2017), and used a Bayesian state-space production assessment model. We used template model builder (TMB), a R package for implementing the assessment model, and estimating all parameters in the model. The predicted annual biomass was in the range of 0.76×10⁶ to 4.06×10⁶ MT, the estimated MSY was 0.13×10⁶ MT, the estimated r was 0.24, and the estimated K was 2.10×10⁶ MT.

The villages in island were established overcoming natural environment through Shamanism and changed by developing various industrials like transportation. Gapa Island located in southern part of Jejudo is flat topography different from the other islands. The purpose of this study is to clarify characteristics on transformation of community space in Gapa Island. For purpose, community spaces in Gapa Island are researched such as establishment, function, change, and use of community space. Spatial components in Gapa Island are like as spaces in faith, residential area, area for production, commercial zone, community space, education facilities, public offices, port, and roads. The methods of this study are literature research and interview survey for residents in Gapa Island. The results are as followings: First, community space is in charge about social, industrial, and religious function. Second, for traditional spaces separated for male and female, demarcation of space does not exist in industrial side but the demarcation has still been exist in religious side. Finally, by development of tourism new community space has been charge in festival function as well as function of space like agora for meeting with people freely, which is relatively various in function of community space in social side. Role of the dock for ship, main transportation of island, is being increasing as square.

The evolutions of human mental capability and technology opened a new era called "Digital Space." Moreover, Digital Space as technology is already accelerating the process of "self-expansion." The expansion, on the foundation of its conceptual and morphological variety, acquired the potential to furnish various types of spatiotemporal experience. This phenomenon, as a necessary consequence of focusing on the resulting value of the human-space relation which came next to its ontological value, requests the value of the space design as an attempt of various phenomenal experience in the relation of technology, human, and space to be educationally established. From a typological point of view, no true creation exists in any form of design. It is practically impossible to design in the void without any restrictions, and all design is based on preceding examples. This is because production of artificial is based on the universal principles or structure residing in history, namely, typology. Considering Digital Space from technological and cultural standpoints, it can obviously be called a new type of space, and beyond that, it becomes a new type of a methodological tool of design. Thus, the purpose of this study is to systematize the paradigm of the space design in the digital era by studying the concept of space in Digital Space from the standpoints of history and context, that is typology, and in accordance with it, classify the phases of the space design that is led digitally.at is led digitally.
