최근 특허권을 포함한 지식재산권에 대하여 다양한 목적으로 가치평가가 이뤄지고 있으며, 특히 특허가치평가를 통한 대출, 보증, 담보용의 평가가 기술금융의 활성화와 더불어 관심이 제고되고 있다. 비록 특허가치평가에 관한 다양한 연구가 진행되어 왔으나, 특허가치평가의 적정성에 관련한 연구는 거의 이뤄지지 않고 있다. 본 연구에서는 기술가치평가의 방법 중 실무에서 가장 많이 사용되는 수익접근법(DCF모형)을 적용하여 산출된 추정가치와 평가이후 수집된 재무제표를 바탕으로 산출한 실제가치를 비교 분석함으로써 특허가치평가의 적정성에 대한 문제를 분석한다. 실증분석 결과, 특허가치 평가액에 대한 추정가치와 실제가치의 차이는 통계적으로 유의미하게 차이가 있다는 것을 확인하였고, 평가업무별로 추정가치와 실제가치가 차이가 있다는 것을 발견하였다. 또한 기술성 평가자에 따른 차이 분석에서는 교수, 변리사, 연구원에 있어서는 차이가 발생하지 않고 있는데 반해 변리사와 기타 평가자간에는 유의한 차이가 있는 것으로 확인되었고, 평가대상 업종별 분석에서도 유의한 차이가 발견되었다.

Objective : Use of quantitative computed tomography (CT) to evaluate bone mineral density was suggested in the 1970s. Despite its reliability and accuracy, technical shortcomings restricted its usage, and dual-energy X-ray absorptiometry (DXA) became the gold standard evaluation method. Advances in CT technology have reduced its previous limitations, and CT evaluation of bone quality may now be applicable in clinical practice. The aim of this study was to determine if the Hounsfield unit (HU) values obtained from CT correlate with patient age and bone mineral density. Methods : A total of 128 female patients who underwent lumbar CT for back pain were enrolled in the study. Their mean age was 66.4 years. Among them, 70 patients also underwent DXA. The patients were stratified by decade of life, forming five age groups. Lumbar vertebrae L1-4 were analyzed. The HU value of each vertebra was determined by averaging three measurements of the vertebra's trabecular portion, as shown in consecutive axial CT images. The HU values were compared between age groups, and correlations of HU value with bone mineral density and T-scores were determined. Results : The HU values consistently decreased with increasing age with significant differences between age groups (p<0.001). There were significant positive correlations (p<0.001) of HU value with bone mineral density and T-score. Conclusion : The trabecular area HU value consistently decreases with age. Based on the strong positive correlation between HU value and bone mineral density, CT-based HU values might be useful in detecting bone mineral diseases, such as osteoporosis.

Evaluating the results of National Nuclear R&D projects has critical importance in nuclear management aspect. This paper uses multi-attribute utility theory as a basis for obtaining a value Index to assess the results of nuclear R&D projects and applies the theory to a specific Korean case study. To structure and quantify basic values for the . evaluation, we elicited important attributes, then refined and structured them into a hierarchy. A multi-attribute index is constructed as a multi-attribute utility function, based on value judgments provided by a group of technical experts, policy makers, and decision-makers. The implications of the results are also discussed. We found that the work and results can provide valuable insights for assessment of nuclear R&D consequences.

Government R&D grants for SMEs have risen to three trillion Korean won a year, placing Korea second among OECD nations. Indeed, analysis results have revealed that government support has not only expanded corporate R&D investment and the registration of intellectual property rights but has also increased investment in tangible and human assets and marketing. However, value added, sales and operating profit have lacked improvement owing to an ineffective recipient selection system that relies solely on qualitative assessments by technology experts. Nevertheless, if a predictive model is properly applied to the system, the causal effect on value added could increase by more than two fold. Accordingly, it is important to focus on economic performance rather than technical achievements to develop such a model.

The deterioration of a shunting locomotive was characterized for the lifetime assessment. The locomotive has been used for shunting works in steel making processes, and in this investigation, various types of technical evaluation methods for the locomotive parts were employed to assess the current deterioration status and to provide important clue for lifetime prediction. Unlike other rolling stocks in railway applications, the diesel shunting locomotive is composed of major components such as diesel engine, transmission, gear box, brake system, electronic devices, etc., which cover more than 70 percent of the total price of the locomotive. Therefore, in this paper, each part of major components in the diesel locomotive was analyzed in terms of the degree of deterioration. The lift-cycle-cost (LCC) analysis was performed based on the maintenance and repair history as compared with economical cost to provide the cost-effective prediction, i.e., to assess either repair for reuse or putting the locomotive out of service based on cost-effective calculation.

The pulp mold attract the increasing concern as recyclable, biodegradable, and eco-friendly packaging materials. In order to broaden the applicability of the pulp mold as substitutes of the expanded styrofoam, the properties of various raw materials for the pulp mold were evaluated and the way for improving water resistance properties of the pulp mold were also tested by applying some additives. The higher value in the fines contents and in the water retention value were shown for the TMP (thermomechanical pulp), which resulted in the bulkier pulp mold with the higher moisture absorption property. In case of water resistance properties, the pulp mold made of white ledger stock showed the higher value in water contact angle and very slow water absorption rate. The addition of oil palm EFB fiber showed the improvement in the water resistance of the pulp mold made of UBKP. The effects of various additives on the improvement in the water resistance properties of the pulp mold were tested by using AKD, PVAm, epoxy resin. The application of AKD leaded to the higher increase in the water resistance. The results in this study showed the effects of AKD for the pulp mold could be improved and optimized by the application with fixing agent and by the ageing treatment after production.

As a new technical approach, a hydraulic and magnetic clamp device was developed to realize a magnetic clamp crane system by simultaneously actuating eight individual hydraulic cylinders. In this approach, an Sr-type of ferritic permanent magnet (SrO· 6Fe₂O₃), rather than the previous electromagnet, was utilized for the purpose of lifting and transporting the large curved steel plates used for manufacturing ships. This study had the goal of developing and manufacturing a hydraulic, magnetic clamp prototype composed of three main parts, including the base frame, cylinder joint, and magnet joint, in order to safely transport curved steel plates. Furthermore, this research included a performance evaluation of the manufactured prototype and acquired the purposed quantity value in the performance test. The most significant item, the magnetic adhesive force (G), was evaluated in a performance test, which utilized a ferritic permanent magnet (Sr type) with 3700~4000 G of residual induction (Br) and 2640/2770 Oe of coercive force (Hc). In particular, relevant items such as the hoist tension (kN), transportation time (s), and applied load (Kgf) on the hydraulic cylinders were also evaluated in order to determine the optimum values.

This study aims to carry out the final evaluation on the deterioration stability of dewaxing and strengthening treatments devised to conserve and restore the beeswax-treated volumes of the Annals of the Joseon Dynasty. Thus, this study artificially deteriorated dewaxed Hanji, strengthened Hanji and beeswax-treated Hanji with optimized processing conditions applied, and comparatively analyzed the deterioration characteristics of each kind of Hanji. As a result of this study, it turned out that there was the loss of physical strength and the value of $L^*$ was increased and the values of $a^*$ and $b^*$ were decreased from removing beeswax after dewaxing by supercritical fluid extraction (SFE). Also deteriorated strength during dewaxing was reinforced by strengthening treatment with methylcellulose and it showed higher strength than beeswax-treated Hanji. From the evaluation on deterioration stability after dewaxing and strengthening, it turned out that deterioration stability of strengthened Hanji is the superior. Therefore, it is presumed that conservation of aged beeswax-treated Hanji can be improved and extended when dewaxing and strengthening are applied under optimum conditions.

Venture business plays a great role in creating national competitive power in every country. In particular, software venture business can mostly belong to manufacturing business, and takes the top seat of core industry as the basis of globalization, informatization and localization as well as the driving force of national competitive power. However, software venture business still has some risks in the whole area of business administration including the process of business starting. There are also problems to be solved in such areas as manager's ability, leadership, talent, level of technical development, marketing channel, recruiting of marketing specialists, financial plan and fund raising. In this respect, this study divides 102 software venture businesses into two; business in the stage of growth and matured business through the analysis of questionnaire and analyzes their present managerial conditions according to their characteristics after classifying them into four categories such as general management, technical development, marketing, finance and accounting. Therefore, this study attempts to provide the basic data useful for business activities of software venture business from now on. The results are as follows; First, it can be judged that software venture businesses make efforts for their technical development in their character, and that they make a great investment in research and development. Consequently, it can be believed that this kind of investment must be continued in the future. Second, it can be seen that they are not much interested in marketing and its manpower. In fact, software venture businesses develop products technically at the risk of their life, while marketing plays an important role in the continuity of business. Thus, it is necessary for them to invest in the supplement of manpower in marketing. Third, it is observed that they generally have some difficulties in raising money from outside. By the way, it. is believed that this problem will be solved by appealing to the persons interested such as investors and creditors, if evaluation system would be developed more exquisitely so that their accounting and technical value may be appraised.
