흡수역량(absorptive capacity)에 관한 활발한 연구에도 불구하고 선 후진국 간의 빈부격차는 심화되고 있으며, 일부 성공사례를 제외하면 개발도상국의 기술혁신 역량의 향상은 기대수준에 미치지 못하고 있다. 본 논문에서는 KIST 설립 사례를 분석하여 개발도상국 측의 흡수역량과 더불어 선진국 측의 새로운 역량이 필요함을 주장하고, 이를 '공유역량(transplanting capacity)'이라 명명 하였다. 기존 연구에서 밝혀진 흡수역량의 핵심요소, 즉 사전지식의 정도 및 노력의 강도에 대비되는 공유역량의 핵심요소로서 개발경험의 성문화(codification), 현지화(localization), 그리고 의지(committment)가 필요함을 제시하였다. 지구 온난화 및 감염성 질병 등 글로벌 이슈에 공동대처, IT기술의 발달 및 신생기술의 출현에 의한 개도국의 혁신 가능성 확대, 개도국 시장의 성장 가능성은 공유역량의 확보가 개도국지원 차원뿐만 아니라 선진국 자신을 위해서 반드시 갖추어야 할 역량임을 보여준다.

The purpose of this study examines the education, knowledge and behavior of radiation safety management among dental workers and compares the education, knowledge and behavior between dental hygienist group and other occupational groups. This study was conducted from November 2nd to November14th, 2019. The survey was conducted on dental workers(dental hygienists, nursing, assistants, coordinators, etc.) who worked in dental hospitals and clinics in Busan area. The tool of this study was modified and adapted to the clinical setting based on the questionnaire. Radiation safety education has 39 dental hygienists who had more education than non-dental hygienists (p=0.286). The most common types of radiation safety education were self-education which usually performed by dentistry, followed by conservative education and others. The average of radiation attitudes, knowledge and behaviors was higher in the dental hygienist group then in the non-dental hygienist group. On the item-specific behavior among employees, the question of 'the radiation should be shielded according to the menstrual cycle or pregnancy of the woman of childbearing' was significant (p<0.05). On the item-specific knowledge between occupations, the question of 'the intensity of X-rays decreases over distance' and 'the individual exposure can be measured by TLD badge or film badge' was significant (p<0.05). Taken together, these results indicate that the dental hygienist group is more concerned about radiation safety and that the dental hygienist group is receiving more radiation safety management training. However, if there is a low level of 'has experienced' in the presence or absence of safety management education, it is difficult to train radiation safety management in dentistry. Therefore, it is considered that dentists should be trained in radiation safety management periodically to pay attention to radiation safety accidents.

Tuberculosis (TB) is a chronic or acute infectious disease which damages more people than any other infectious diseases according to WHO estimates. In this paper, a new automatic detection system of tuberculosis bacilli by using their color information is proposed. Through the deep investigation of color and intensity compositions of tuberculosis images, new pre-processing and segmentation algorithms are suggested. Specific features of bacilli are extracted from the processed images and number counting is done by using domain-specific knowledge rules.

The accumulated knowledge of the influence of solar granulation on spectral lines, i.e. their asymmetry, provides a key to analyze stellar spectral line asymmetries. In this paper, a simple line synthesis using a simple 'model' of granulation was calculated. By adjusting the properties of the granule model, the observed imprints of convection on spectral lines can be reproduced. Since we depict convective flows using a continuous function rather than using a few components of flows (cf. Gray and Toner 1985, 1986; dravins 1990), we were able to identify which components of convection are important in line bisector shapes. The results of this study can be summarized as follows: Firstly, the intensity contrast (i.e. temperature fluctuation), and the area coverage of up- and down-flows are the two important factors which determine the line bisector shapes. Secondly, on the contrary to the assumption of other studies, the effect of horizontal flows is non-negligible. This exercise provides a qualitative understanding of the effect of convection on spectral lines. This knowledge serves as a guideline for understanding the characteristic difference in convection for stars on either side of the 'Granulation Boundary' (Gray 1982; Gray and Nagel 1989).

This paper presents a study on characteristics and safety for human body in ELF electric and magnetic fields using statistical method. The magnetic fields from a power line can be computed given a knowledge of the currents, voltage and geometry of the line. In this paper, a statistical method for predicting the magnetic fields given the inherent indetermination of the currents is presented. But the electric field is calculated given a knowledge of the voltage and geometry of the line. The effect of unexpected fluctuations in current is modeled by the Monte Carlo simulation. The suggested method is applied to the 345kV and 765kV transmission line system, the result shows that the maximum electric and magnetic field intensity is 6.8627kV/m and 284mG in 345kV system, 2. 5590kV/m and 35mG in 765kV system, respectively.

Singapore's inward and outward investments with industrialized countries in both manufacturing and service sectors were skill seeking while outward investments to developing countries were labor seeking. Applying the Knowledge-Capital model, it was found that services Foreign Direct Investment is sensitive to skill differences. A ten-percent decline in skill differences with industrialized countries resulted in a 4.25 percent rise in inbound manufacturing and 1.48 percent rise in inbound services investments. Meanwhile, a ten-percent increase in skill differences with developing countries resulted in a 30 percent rise in outbound manufacturing and 0.38 percent rise in services investments. Furthermore, when services are distinguished by skill-intensity, the impact of relative skill endowments on inbound Foreign Direct Investment in skill-intensive services is significantly different from the impact on other services. However, when services are disaggregated by "proximity" needs, we do not find any significant difference in the impact of relative skill endowments on Foreign Direct Investment.

This paper empirically investigates potential factors that might affect firms' incentives to license out technology. The analysis is done with the help of a panel data set of observed licensing transactions involving U.S. public companies in high-technology industries. The important explanatory factors relate to the firm characteristics such as the company's stock of technological knowledge (patent stock). prior involvement in technology licensing. the company size, R&D intensity and capital expenditure. The results suggest that there seems to be significant inter-sectoral differences as well as similarities in determinants of the propensity to transfer technology through licensing agreements.

Purpose: This study was intended to measure the knowledge and attitudes of nurses working in a psychiatric ward regarding the subject of pain. Methods: In this descriptive study, data were collected in psychiatric wards(or hospitals) located in the Kyungnam and Kyungpook area from December 2013 to January 2014, using a modified version of the McCaffrey and Pasero Clinical Manual Survey Regarding Pain. The content of the survey follows a logical progression from common pain management problems through mechanisms of pain, assessment and pharmacology. Results: The average score of knowledge regarding pain was roughly $21.59{\pm}2.93$ among the 181 participants. The nurses selected Tylenol as the preferred choice (81.2%). Seventy-one percent of respondents didn't use Pain Intensity Instruments during the pain assessment. The subjects preferred the Numerical Rating Scale rather than Visual Analogue Scales. Pharmacology questions were the least likely to be answered correctly. No specific correlations were found between score and demographic variables of age and experience. No specific correlation between score and educational level was noted. Conclusion: Nurses require ongoing education on pain management, particularly regarding pharmaceutical agents.
