  • Human emotion is the issue which is subjective, difficult to define and even more difficult to measure because it's personal. In general, the methods for measuring human emotion is divided in two, one is the psychological way based on user's subjective evaluation and another is the physiological way based on physiological signs. However, these methods have some limitations. Therefore, in this study we suggested the methods for measuring users emotion in the natural and accessible environment for the design field. In order to observe user's emotional changes while they interact with a product, we have extracted some emotional words and representative emotions, and made a set of subjective evaluation scales. With these scales, emotion logging program 'VideoTAME' was developed as an effective measurement tool for complementing the current psychological methods. In the testing module of 'VdeoTAME,' participants evaluate their emotional changes through playing and watching the video dips of their performing tasks in the experiment room. In the analyzing module, the researchers replay the results created by participants during the experiment and analyze the results using Microsoft Exel. It is hoped that this study will be of great help for designers for effective measurement of user's emotions naturally expressed while using a product.

  • Recently, a variety of AI-based platform services are available, and one of them is ChatGPT that processes a large quantity of data in the natural language and generates an answer after self-learning. ChatGPT can perform various tasks including software programming in the IT sector. Particularly, it may help generate a simple program and correct errors using C Language, which is a major programming language. Accordingly, it is expected that ChatGPT is capable of effectively using Verilog HDL, which is a hardware language created in C Language. Verilog HDL synthesis, however, is to generate imperative sentences in a logical circuit form and thus it needs to be verified whether the products are executed properly. In this paper, we aim to select small-scale logical circuits for ease of experimentation and to verify the results of circuits generated by ChatGPT and human-designed circuits. As to experimental environments, Xilinx ISE 14.7 was used for module modeling, and the xc3s1000 FPGA chip was used for module embodiment. Comparative analysis was performed on the use area and processing time of FPGA to compare the performance of ChatGPT products and Verilog HDL products.

  • This study aims to analyze space planning of accommodations in seven closed schools involved in experiential activity programs on Jeju Island, a famous tourist destination in Korea. The results are as follows. First, 35 schools had been closed down in Jeju between 1982 and 2015. Among them, four closed schools were sold, three are currently used by the Jeju special self-government provincial office of education, and 25 are being leased by individuals, village organizations, and other entities. However, they have not been well-operated, and so strategies for the effective management or operation of these closed schools should be developed. Second, there are distinctive differences in space planning of accommodations based on the correlation between experiential activities and the types of participants. If the experiential activity participants are mainly individuals or small groups, the closed school is likely to plan double-bed accommodations and individual bathrooms rather than large group rooms. Third, in order to operate experiential activity programs, closed schools require four different spaces for experiential activities, lodging, dining, and sanitation. The largest space available in each school building is used for experiential activities, and original classrooms are still in use. According to the standard drawing of school architecture, standard classroom size since 1997 has been $7.5{\times}9$ meters, and lodging rooms have mainly been re-planned based on the module of the standard-sized classroom. School cafeterias are utilized as dinning and kitchen spaces. For sanitation purposes, original school restrooms are still used by experiential program participants, while the shower rooms are newly equipped.

  • An OS requires the device driver to control hardware IPs at application level. Development of a device driver requires specific acknowledge for target hardware and OS. In this paper, we present a system which generates a device driver together with an interface circuit. In the proposed system, an efficient device driver is generated by selecting a basic device driver skeleton, a function module code, and a header file table from the pre-constructed library and an interface circuit is constructed such that the generated device driver operates correctly. The proposed system is evaluated by generating a TFT-LCD device driver on the ARM922T core with 3.5 inch Samsung TFT-LCD in ARM-Linux environment. Experiment result shows that the writing time on the LCD is decreased by 1.12% and the compiled code size is increased by 0.17% compared to the manually generated one. The automatically generated device driver has no performance degradation in the latency of hardware control at the application program level. The system development time can be reduced using the proposed device driver generation system.

  • This study aims to examine how much Korean's family value orientations and gender role attitudes are different from those of U.S.A., Sweden, and Japan, and how demographic variables influence family value orientations and gender role attitudes across the countries. By using 2004 Korea General Social Survey data and 2002 International Social Survey Program family module, multiple regression analyses showed that Korean's family value orientations and gender role attitudes were much more traditional than those of U.S.A., Sweden, and Japan, even after controlling demographic variables. Furthermore, each country showed a distinct pattern in the impact of demographic variables on family value orientations and gender role attitudes. Among the demographic variables, age and marital status were statistically significant indicators of family value orientations for all the countries. However, gender, the year of education, and employment status effected on family value orientations only in some countries. The findings of this study showed that Korea was still traditional in terms of family value orientations and gender role attitudes, compared with U.S.A, Sweden, and Japan. Although family value orientations were more traditional in Korea than in the other countries, all the countries showed similar patterns of explaining mechanism in the effect of demographic variables on family value orientations. People who were men and married were likely to be more traditional than those who were women and unmarried. However, gender role attitudes showed interesting results. All the demographic variables were significant predictors of gender role attitudes for Korea, whereas only some of demographic variables were statistically significant indicators of gender role attitudes for other countries. That is, Korean society showed strong attitudinal differences on the basis of demographic variables. The implication of these differences was discussed.

  • This study tried to propose the guidelines for the ecological preservation zoning in Korea. So some related laws and regulations were inspected, which were Natural Environment Preservation Act, Nature Park Act, Cultural Asset Conservation Act, Forest Act and Urban Planning Act. In these acts, I could find several concepts related to the ecosystem that are described as the protection area. But there aren't detailed and practical characteristics in those concepts. So for making the practical concept of ecosystem preservation, I considered Multiple Use Module, Wildlife habitat model, and Environmental evaluation model. Thorough this step, the process and methodology was established for evaluating and analysing. The potentiality of the GIS system was inspected. So the TM5 scene of the site was acquired and processed by ER-Mapper, Idrisi, Arc/Info and Arcview. And several digitized data were input by scanning and vecterizing. The Erdas format was mostly exchangeable to any program. The site is the Byonsan Peninsula National Park. The forest stand information and topographic data were digitized, types of which are forest year, DBH, density, slope, aspect etc. And also the watershed boundary, roads and paths, natural and cultural resources were mapped and analysed. Modelling of preservation suitability found the dispersed patterns for the best suitable zone through all the site. And the development potential areas were checked on downwatershed. This patterns are thought to result from the forest location for the wildlife habitat and the low altitude and no-steep slopes for developing. And Early warning system concept was introduced by overlapping these two patterns on the both potential area. As the conclusions, I proposed that the preservation zone be assigned according to the watershed unit as the main ecosystem zone. This main area should be linked by the eco-corridor through the point type eco-system. Finally, I thought the comprehensive information system should be established for making the rational and efficient decision making in natural area.
