박지현(Park, Ji-Hyun),권기정(Kwon, Gee-Jung) 한국회계정보학회 2021 재무와회계정보저널 Vol.21 No.1

[연구목적] 직무발명보상금이란 발명진흥법 제15조 등에 의하여 종업원 등이 직무에 관하여 발명한 것에 대하여 정당한 보상을 하도록 하는 것을 말한다. 즉, 직무발명보상금 제도는 종업원 등이 직무발명의 권리를 사용자가 승계할 경우 법률에 의하여 보상을 하도록 법률적으로 제정한 보상제도이다. 그러나 제도의 취지와는 다르게 소득세법이 개정되어 다양한 분야에서 소득세법 재개정을 주장하고 있다. 따라서 본 연구에서는 직무발명제도에 대한 이해를 바탕으로 직무발명보상금의 소득세법상 과세체계의 문제점에 대해 알아보고 이에 대한 개선방안으로 제시하고자 하였다. [연구방법] 직무발명보상금에 대한 제도의 취지와 우리나라의 소득세 개정현황을 살펴보고 주요국의 관련 세법에 대한 문헌연구를 통해 우리나라 직무발명제도의 과세체계의 문제점을 제시하였다. 이러한 문제점을 바탕으로 소득세법상 직무발명 보상금 과세제도에 대한 개선방안을 제시하였다. [연구결과] 직무발명보상금의 법률적 성격과 유사 소득과의 과세형평성 등을 검토하였을 때 직무발명보상금은 기타소득으로 규정하는 것이 타당하다. 그리고 직무발명보상금에 대하여는 비과세 한도를 현행 500만 원에서 국가연구개발의 기술이전에 따른 직무발명보상금 평균인 1,500만 원으로 조정할 필요가 있을 것이다. [연구의 시사점] 직무발명보상금 제도는 국가의 경쟁력을 확보하는 차원에서 매우 중요한 역할을 해왔다. 따라서 연구개발을 통해 경쟁력 있는 지식재산권을 확보하고 이를 활용하여 기업의 생산효율 및 일자리 창출을 증가시키고 국가 및 기업의 경쟁력을 강화하기 위한 선순환 구조를 만들기 위해서는 관련 법률들 간의 모순점을 해결하고 직무발명보상금 제도의 과세체계를 개편할 필요가 있다. [Purpose] The term compensation for occupational inventions refers to the compensation of employees, etc. for their inventions in relation to their duties pursuant to Article 15 of the Invention Promotion Act. In other words, the compensation system for job inventions is a compensation system legally enacted so that employees, etc., make compensation in accordance with the law when the employer succeeds in the rights of job inventions. However, contrary to the purpose of the system, the income tax law has been revised, and various fields are advocating for the revision of the income tax law. Therefore, in this study, based on the understanding of the job invention system, the problem of the taxation system under the income tax law for compensation for job inventions was investigated and suggested as a solution for this. [Methodology] The purpose of the system for compensation for occupational inventions and the current status of revision of income tax in Korea were examined, and the problem of the taxation system of the Korean occupational invention system was presented through literature research on related tax laws in major countries. Based on these problems, a plan to improve the taxation system for compensation for job inventions under the Income Tax Act was suggested. [Findings] When examining the legal nature of the compensation for job inventions and the taxation equity with similar income, it is reasonable to stipulate the compensation for job inventions as other income. In addition, it will be necessary to adjust the tax-free limit of compensation for job inventions from the current 5 million won to KRW 15 million, which is the average of compensation for job inventions from the technology transfer of national R&D. [Implications] The job invention compensation system has played a very important role in securing national competitiveness. Therefore, in order to create a virtuous cycle structure to secure and utilize competitive intellectual property rights through research and development to increase the production efficiency and job creation of companies, and to reinforce the competitiveness of the country and companies, it is necessary to resolve the contradictions between relevant laws and provide compensation for job inventions. There is a need to reorganize the tax system of the system.

Kyphoscoliosis is a disease manifested as lateral curvature of spine and accompanying rotation of the vertebrae, resulting in distortion of rib cage. Restrictive lung disease and pulmonary hypertension progressing to cor pulmonale are the major cause of mortality in patients with kyphoscoliosis. We had experienced a successful spinal and caudal epidural anesthesia for the open reduction and internal fixation with plate of fractured femur shaft in two patients with severe kyphosoliosis. We had chosen regional anesthesia as an anesthetic method because of there poor pulmonary function and severe deformities of thoracolumbar spine. We could achieve the adequate anesthetic sensory dermatome level, T_(5) and T_(8), for operation without any significant deterioration of blood pressure and respiration. We recommended that regional anesthesia is a useful anesthetic method for a patients with severe kyphoscoliosis when the operation on hip or lower extremity is required.

오지현,권근희,김남철 공주대학교 생산기술연구소 2002 論文集 Vol.10 No.-

This paper presents ferroelectric Pb(Zr_0.52Ti_0.48)O_3 (PZT) thin film by sol-gel synthesis with metal-organic precursors. Sol-gel reaction sequences with metal-organic precursors were confirmed through DTA and FT-IR measurements and perovskite phase formation was investigated by rapid thermal annealing technique. The structural and morphological properties of PZT thin film were investigated by XRD and SEM. Perovskite phase PZT single phase was appeared at temperature of 650 ℃ and the second phase, pyrochlore, was decreased as increasing the annealing temperature, which was clearly indicated by investigating the size of 'rosette structure' and pyrochlore phases at different annealing temperatures. The P-E loop measurement indicated the relation of the applied voltage vs. domain alignments in the PZT thin film system.

The purpose of this study was to evaluate the effect of adhesive curing timing on the direction of polymerization shrinkage of light-curing composite resin. In this study, the curing times of adhesive and composite resin were measured by differential scanning calorimeter(DSC). 28 extracted human molars were embedded in clear resin and box-type cavities were prepared. Based on DSC data. the experimental teeth were divided into 4 groups. Group 1: no bond: Group 2: late curing: Group 3: Intermediate curing: Group 4: Early curing. After treating with adhesive, the buccal cavities were filled with Z-100 hybrid composite resin and the lingual ones were filled with AEliteflo flowable composite resin. The depressions at the surface were measured by surface profilometer, then the specimens were embedded in clear resin and sectioned. Impressions were obtained and used to get epoxy resin replicas. The epoxy replicas were gold-coated and observed under SEM. Average Maximum Gap(AMG), Gap Proportion(GP), Average Marginal Index(AMI) were used to compare the shrinkage gap of each group. The results were statistically analyzed using the Kruskal-Wallis One Way ANOVA, Student-Newman-Keuls method. The results of this study were as follows. 1. Average Maximum Gap. Gap Proportion, Average Marginal Index and depression at the surface of Z-100 hybride composite resin were smailer than those of AEliteflo flowable composite resin(P(0.05) 2. When the bonding between composite resin and tooth structure was strong, the shrinkage gap was small, and depression at the surface was deep(P<0.05). 3. In the well-bonded group. light-curing composite resin shrank toward bonded cavity wall. not toward light source. The result suggested that the direction of polumerization shrinkage was affected by the quality of bonding in the dentin-resin interface. The strong was the bonding between composite resin and tooth structure, the smaller was the gap and the deeper was the depression at the surface. Then the flow to compensate the polymerization shrinkage proceeded from surface to bonded cavity wall.

Drug resistance, whether acquired as a result of inappropriate or inadequate chemotherapy or from an individual whose organism was drug resistant, may present serious obstacles to the eradication of tuberculosis. The authors attempted direct drug susceptibility test to various primary and second line antitubereulosis drugs on 139 isolates from pulmonary tuberculosis patients who have been hospitalized at National Kongju Hospital for tuberculosis. The results were summarized as follows; 1. Out of 101 tuberculosis patients, male patients were slightly more than female as a ratio of 1.59: 1 and the average age of onset was 30 years. 2. The number of patients who have been suffered from pulmonary tuberculosis more than 6 years was 61 (60.4%). 3. A11 of 139 isolated tubercle bacilii were resistant to one or more antituberculosis drugs. 4. Out of 139 isolates, 94.2% was resistant to INH, 89.2% to EMB, 75.5% to SM, 63.3% to PZA, 56.1% to RMP,47.5% to KM, 42.4% to PAS, 27.3% to CS, 16.5% to PTA and 2.9% to TUM. 5. Resistances to INH-SM-PAS, INH-SM-EMB, INH-SM-RMP, INH-EMB-RMP, PTA-PZA-CS and INH-SM-TUM were 36.0%, 69.1%, 41.0%, 46.8%, 7.2% and 2.9%, respectively. 6. Resistances to INH-EMB-RMP-PZA and INH-SM-RMP-PZA were 31.7% and 27.3%, respectively.
