In a knowledge-based economy, intangible assets such as intellectual property(e. g., patents, trademarks, etc) are recognized as key assets for competitiveness. The significance of trademarks in establishing distinctiveness and reputation for products has gained substantial attention, leading to a notable surge in trademark-related activities. Since the early 2000s, previous research on trademarks has explored various dimensions, including their role as indicators of innovation and their economic effects. However, much of this research is still in its infancy, especially at the national level. In this study, we have delved into the influence of trademark activities on a nation's economic performances. In the research, the impact of trademark activities on the economy was examined. To reflect the industrial structure of the analyzed countries, they were divided into manufacturing-centric and service-centric nations. Data for the recent 26 years (1996 to 2021) were collected, and a panel analysis was conducted on the relationship between trademark applications and economic performance. The results showed that in both groups, a higher number of trademark applications per capita was associated with larger production and export scales. A 1% increase in trademark applications per thousand people led to a 0.44% increase in per capita GDP, 0.53% increase in goods exports, and 0.99% increase in service exports in manufacturing-centric nations. In service-centric nations, the same increase resulted in a 0.22% increase in per capita GDP, 0.11% increase in goods exports, and 0.52% increase in service exports. Particularly in manufacturing-centric nations, trademark applications were found to have a greater impact on the economic performance. This study is significant in examining the influence of trademarks on the economic performance at a national level, considering the characteristics of the industrial structure.

We numerically investigate the effect of the dipole orientation on the light emission characteristics of a three-dimensional top-emitting organic light-emitting diode (TOLED) with square pixel boundary, based on the finite element method. The spatial profiles of the optical power flows and the output angular emission characteristics are calculated in various horizontal positions of a single dipole with the x-, y- and z-directed dipole orientations. The total angular emission characteristics of the TOLED are obtained by summing the individual angular emission characteristics of 100 dipole emitters, which are assumed to be uniformly distributed within the square pixel boundary. The angular emission pattern of the y-directed dipole emitters exhibits an approximately 10% higher intensity with a narrower linewidth than that of the x-directed dipole emitters. This difference in the angular emission patterns of the x- and y-directed dipole orientations can be attributed to the dipole orientation dependent internal radiation pattern, which has different spectral power densities as a function of the internal emission angle and light polarization. In addition, the average angular emission characteristics of the randomly oriented dipole emitter are calculated by averaging over those of the x- and y- directed dipole emitters.

Effect of Sunlight Polarization on the Absorption Efficiency of V-shaped Organic Solar Cells
강경남,김정호 한국광학회 2014 Current Optics and Photonics Vol.18 No.1
We numerically investigate the effect of sunlight polarization on the absorption efficiency of V-shaped organic solar cells (VOSCs) using the finite element method (FEM). The spectral distribution of absorbance and the spatial distribution of power dissipation are calculated as a function of the folding angle for sand p-polarized light. The absorption enhancement caused by the light-trapping effect was more pronounced for s-polarized light at folding angles smaller than 20°, where s-polarized light has a relatively larger reflectance than p-polarized light. On the other hand, the absorption efficiency for p-polarized light is relatively larger for folding angles larger than 20°, where the smaller reflectance at the interface of the VOSC is more important in obtaining high absorption efficiency.

In Korea, the Invention Promotion Act (the “Act”) is designed to include compensation system for inventions which fall within the scope of the employer's business and which result from any action(s) categorized as present or past duties of the employee(Kang, 2016). In this study, implementation status of invention compensation system in SME(small and medium-sized enterprises) was surveyed. CEO/CTO’s perception of an employee invention compensation system was also surveyed. The impacts of the perception levels of CEOs/CTOs on their judgement were investigated using an ordered logistic regression model. The results showed that the level of CEO/CTO's awareness affects CEOs/CTOs’ judgement on monetary compensation and R&D investment decision. The study findings signify the importance of enhancing the awareness of CEOs/CTOs about employee invention compensation system(Kang, 2016). 본 연구에서는 직무발명제도를 도입한 중소기업을 대상으로 직무발명제도 운영의 구체적인 현황을 조사하는 한편, 경영자의 제도에 대한 인식수준을 파악하고자 하였다. 조사결과, 최근 5년간 직무발명보상을 실시한 경우 금전적 보상을 실시한 기업이 72.9%, 비금전적보상을 실시한 기업이 51.4%, 금전적 보상과 비금전적 보상을 모두 실시한 기업이 31.4%로나타났다. 보상실시 유형에 따라 경영자 인식 수준을 비교한 결과, 금전적 보상을 실시하지않은 기업에 속한 경영자의 제도에 대한 지식수준이 상대적으로 낮은 것으로 확인되었다. 기업 경영자의 직무발명에 대한 ‘제도 지식수준’과 제도 운영의 ‘효과 인식수준’이 회사의직무발명 활성화 ‘지원 필요성’에 대한 경영자의 판단에 영향을 미치는지 확인한 결과, 기업경영자의 ‘제도 지식수준’이 높을수록 직무발명에 대한 금전적 보상 수준을 높이고, 연구개발비를 증대할 필요가 있다고 생각하는 것으로 나타났다. 중소기업 직무발명 활성화를 위해직무발명제도에 대한 경영자 인식제고 노력이 필요하다고 판단된다.

The purpose of this study were to investigate musculoskeletal disorders state among some manufacturing workers and the necessity of industrial physical therapist. The relationship between the self-reported musculoskeletal symptoms and related factors among workers in manufacturing industries. Information on general characteristics, occupational characteristics, and musculoskeletal symptoms were obtained by a self-administered questionnaire between July and October in 2004, from 104 workers in Gimhae City and Ulsan City. The data were analyzed by descriptive analysis, crosstabs analysis, and χ2-test using SPSS PC Version 10.0 for Windows program. The result were as follows; 1. The prevalence of occupational musculoskeletal disorders on shoulds are topping for 50.0%, hand/wrist is followed for 46.2%, leg/foot 41.4%, low back 39.7%, neck 33.7%, and arm/elbow 26.9%. 2. The pain degree of the standard of among a characteristic connected with it in relation to occupational musculoskeletal disorders is in order of answer, middle, low, severe, absence, highly severe. And the most people gain musculoskeletal disorders in the workplace than out of workplace. 3. The treatment time among experienced of treatment is, in order of answer, after work time, holiday, work time. 4. The kind of worker were treated for physical therapy is, in order of electrical therapy, exercise therapy, hydrotherapy. 5. The leaving work early by musculoskeletal pain is 12.5%, temporary retirement from workplace by musculoskeletal pain is 3.8%. 6. The difficulty things by work were difference between difficulty by work and the following others; existence of pain within one week, reasons of not to treat, bad effects that workers stress to transfer from workplace to hospital, existence of work difficulty problem with commuting treatment, physical effort for work, overload work, work in the uncomfortable position, repetitions of work. 7. The results reveal that it were difference between difficulty by work and the following others; existence of pain within one week, reasons of not to treat, bad effects that workers stress to transfer from workplace to hospital, existence of work difficulty problem with commuting treatment, physical effort for work, overload work, work in the uncomfortable position, work repetitions. 8. The most profit number to the physical therapist in workplace was, in order of answer 2, 3, 1, 5, 4 persons and the others. The further studies would be continue to musculoskeletal disorders state among several manufacturing workers and the necessity of physical therapy room in a workplace. We not only study from a physical therapist's point of view this research, but also study from a workers point of view of asking for help treatment. It is necessity to study about standard evaluation form for industrially developed musculoskeletal disorders.
