  • Taiwan's economy has been characterized by the strong existence and continuous creation of small and medium-sized enterprises. This phenomenon is commonly regarded to be the result of a culturally embedded strong entrepreneurial spirit. In the process of developing a high-technology industry in southern Taiwan, linking a newly established science park with existing local industries was one of the major challenges. This article reviewed the development history of Tainan Technopolis. Following a concise review of Southern Taiwan Science Park's struggle against becoming an assembly of spillover establishments from Hsinchu Science Park, the authors focused on the efforts of incubating startups. Although only an initial study, the authors demonstrated the roles of National Cheng Kung University and Southern Taiwan Science Park Administration in introducing a two-track incubation system based on collaboration between the two institutions and startups.

  • The purpose of this study was to evaluate the effects of Kinesio taping(KT) on the maximal power and muscle activity of erector spinae. 30 male subjects were allocated in this study and randomly divided into experimental and control groups. All subjects were measured for maximal power of trunk extensors and muscle activities of iliocostalis lumborum, longissimus, and multifidus between pre and post experiment. Maximal power was calculated using a dynamometer(Power Track II, JTECH medical, USA), and muscle activities were calculated using a surface EMG(MP150 BIOPAC System Inc. CA. USA). Maximal power of trunk extensor showed no significant difference between pre and post intervention in both groups(p>0.05). Muscle activity of iliocostalis lumborum, longissimus, and multifidus showed no significant difference between pre and post intervention(p>0.05). Finally, there was no significant difference between Experimental and control group in maximal power and muscle activity of trunk extensor. These study results suggested that KT did not affect increase or decrease in maximal power and muscle activities of trunk extensor.

  • Recently, the United Nations Commission on International Trade Law (UNCITRAL) has made progress toward resolving low value, high volume disputes in international e-commerce. At the Working Group's 26th session, two draft procedural rules were addressed. The first discussed the draft of Article 9, entitled "Decision by a neutral party." This is based on the suggestion in 26th session to have a "two track" system of ODR, one including negotiation, facilitated settlement, and arbitration phrases, and the other not including an arbitration phase. The second draft procedural rule, draft Article 10, regards the language of proceedings. In most cases of international e-commerce, the decision of language of an ODR proceeding is a matter of importance, for the language parties could differ from each other. This paper examines several implications of UNCITRAL for Korea, which has unstable ODR system.

  • We introduced a scheme for finding an optimal data association matrix that represents the relationships between the measurements and tracks in multi-target tracking (MIT). We considered the relationships between targets and measurements as Markov Random Field and assumed a priori of the associations as a Gibbs distribution. Based on these assumptions, it was possible to reduce the MAP estimate of the association matrix to the energy minimization problem. After then, we defined an energy function over the measurement space that may incorporate most of the important natural constraints. To find the minimizer of the energy function, we derived a new equation in closed form. By introducing Lagrange multiplier, we derived a compact equation for parameters updating. In this manner, a pair of equations that consist of tracking and parameters updating can track the targets adaptively in a very variable environments. For measurements and targets, this algorithm needs only multiplications for each radar scan. Through the experiments, we analyzed and compared this algorithm with other representative algorithm. The result shows that the proposed method is stable, robust, fast enough for real time computation, as well as more accurate than other method.

  • A body dysmorphic disorder refers to a state that individuals whose external appearance is normal consider their appearance to be meta-morphosed, or think there's something wrong with it, or view a trifle deficiency as severely disfigured. The purpose of this study was to examine the body dysmorphic disorder and depression of health-related and health-unrelated majors in an effort to compare the two groups. And it's also meant to investigate the relationship between body dysmorphic disorder and depression. The subjects in this study were 400 students at K college located in Gangwon Province. Out of them, the major of the 200 students belonged to the health science track, and that of the 200 students didn't. After a self-administered survey was conducted, the answer sheets from 319 respondents were analyzed. As a result, there appeared no differences between the health-related majors and the health-unrelated majors in body dysmorphic disorder. Although there might be various factors to concern body dysmorphic disorder, both groups found themselves to suffer from more depression when they had a severer body dysmorphic disorder, and their body dysmorphic disorder exerted a statistically significant influence on their self-rated depression. Therefore the careful management of body dysmorphic disorder was required, and it's especially needed to make research in that of health-related majors. At the same time, more detailed clinical research efforts should be directed into body dysmorphic disorder and self-rated depression.

  • This study was performed to investigate the concentrations of PM($PM_{10}$, $PM_{2.5}$, $PM_{1}$) and it's affecting factors in the subway from line 1 to line 8 in Seoul metropolitan area, from Sep. 1 to 30, 2005. PM concentrations were measured at the entrances and centers in subway passenger cabins by a light scattering equipment. And the affecting factors to PM were estimated based on the number of passenger, door open and close and running area etc. The geometric means of $PM_{10}$, $PM_{2.5}$ and $PM_{1}$ concentration in Seoul subway passenger cabins were $214{\mu}g/m^3$, $86.6{\mu}g/m^3$ and $27.0{\mu}g/m^3$, respectively. These mean concentrations in subway carriage were higher when it ran on an underground track than on a ground track. And running time(7AM-9AM, 11AM-13PM, 6PM-8PM) significantly influenced to the concentrations of $PM_{10}$, $PM_{2.5}$ and $PM_{1}$. Daily profile of $PM_{10}$ and $PM_{2.5}$, $PM_{1}$ expressed as an 10 minutes average, showed similar variation pattern over day period. In correlation analysis, significant relations among $PM_{10}$, $PM_{2.5}$ and $PM_{1}$ were detected(p〈0.01). In particular, correlation coefficient between $PM_{10}$and $PM_{1}$ was highly significant(r=0.94). Further study is needed to identity the sources of PM in subway cabins and to compare pollutants concentration among subway lines.

  • This study aims to investigate how high school teachers and students perceive the purpose of science learning. Participants were high school science teachers and students from one hundred and sixty high schools nationwide, which were selected through proportional stratified sampling method. Teachers and students responded on open-ended questionnaires about the purpose of science learning. The data were analyzed using the semantic network analysis method. Our study illustrates three major finding: First, teachers recognized the intrinsic value related to cognitive domain as the more important purpose of science learning, while students recognized the extrinsic value related to personal usefulness domain as more important. Second, teachers' responses were significantly different depending on the teaching career. Beginning teachers believed both intrinsic and extrinsic values were equally important, while experienced teachers believed the cognitive domain about understanding of scientific knowledge was more important than intrinsic values. In other words, the differences in perception of the purpose of science between teachers and students, the experienced teachers is greater than the beginning teachers. Finally, students' responses were different depending on their academic track. Humanity major students recognized that learning science made their everyday-life easier while science major students recognized that learning science should be related to their future careers. In conclusion, the results of this study is expected to be of use as the basic data to identify the characteristic of teachers and students related to science.

  • The high-tech industry, a highly knowledge-intensive industry based on advanced technologies such as electronics, new materials, and IT, is developing rapidly centering on the semiconductor, display, and battery fields. The market size of this industry is continuously increasing, and various challenges are coming forward due to various factors such as changes in the market, changes in demand, and the requirements of the clients. Many strategies are being implemented to advance the start-up time of factories, such as fast-track construction and basic line construction. Therefore, construction of high-tech factory is required to respond to various types of construction plans and early decision making, and an accurate and reliable method of calculating construction costs is needed. In this study the existing construction type was classified into the overall line configuration considering the total production of the factory, and a basic line configuration for quick production start-up. The correction ratio/value for each detailed construction required to calculate the construction cost of the basic line configuration type was derived. Finally, reliability and accuracy were verified by applying the correction ratio suggested in this study to a new high-tech factory construction project.

  • This study examined the effects and roles of transmedia such as trailer (i.e., trailer) and webtoon OST (i.e., Original Sound Track), which have recently served as extended content in webtoons. In recent years, the number of transmedias using webtoons has increased rapidly, and production and consumption in various directions have been taking place. However, studies on whether these contents lead to positive emotions and attitudes toward webtoons are not actively conducted. Therefore, this paper examined the effect through loyalty and perceived enjoyment, and found that 'increasing immersion in content through transmedia' plays a major role as a major variable. In addition, it is determined whether these mechanisms appear differently by gender, and in the case of women, media consumption tends to be based on emotional signals compared to men, so transmedia will further increase the level of immersion, but webtoon content did not show gender effects on media consumption. This is a meaningful result that shows that in general, media consumption methods according to gender appear differently in webtoons. Therefore, based on the results, this study presented directions and implications to keep in mind when planning the production of various transmedias using webtoons.
