본 연구의 목적은 정부출연연구소에서 연구개발된 기술이 민간부문에서 충분히 활용되지 못하고 있다는 문제의식으로부터 출발하여, 원천, 핵심기술의 확보가 국가경쟁력을 좌우하는 첨단기술경제시대에 막대한 국가자금으로 연구개발된 우수한 기술의 사장을 방지하고 궁극적으로 국가경제발전을 위한 전략적 기술이전 촉진 방안을 모색하는 것이다. 현재 국무총리산하 기초, 산업, 공공기술 연구회로 분류 조직되어 있는 3개 연구회 총 1개 정부출연연구소의 지난 10년간(1992-2001)의 연구예산규모, 보유특허수, 기술이전건수, 기술징수액, 기술실시계약서를 방문 조사하고 각 연구소의 기술이전전담조직의 실무자를 대상으로 설문 조사하여 설문 및 통계분석 결과를 토대로 기술이전관련 문제점 파악 및 기술이전 촉진을 위한 전략적 개선방안을 모색해 보았다. 먼저 기술이전 현황을 살펴보면 기술이전건수는 보유특허수의 3%미만, 기술료 징수액은 연구예산규모의 2%미만으로 기술이전 및 기술상업화율이 상당히 저조하다. 설문 및 통계분석 결과로부터 TLO 조직의 비효율적인 운영, 비전문성, 열악한 운영인력, 적극적인 기술이전을 위한 동기부족, 정부의 제도적인 지원부족, 기술실시계약서 조항들의 경직성 등을 기술이전 관련 문제점으로 도출해 낼 수 있었다. 이러한 문제점을 극복하고 기술이전 촉진을 위한 개선방안으로는 첫째, TLO 조직을 전략으로 개편해야 한다. 즉 기술이전 전담인력을 변리사, 전문 협상가, 연구원 둥 전문가들로 구성하여 지적재산권 관리, 기술평가, 시장조사, 기술마케팅, 사후관리 등을 효율적으로 수행해야 한다. 둘째, 정부의 정책적인 지원이 필요하다. 기술이전 전담조직에 대한 인센티브 시스템 기술이전을 위한 특별예산 편성 등을 정책적, 제도적으로 도입하는 등의 적극적인 지원이 요구된다. 셋째, 기술실시계약서 조항들을 기술실시자의 실질적인 기술 상업화에 도움이 되고 기술 유출 및 기술사장화를 방지하는 방향으로 개선하여야 한다. 특히, 전용실시권과 실시대가, 기술실시 및 지적재산권 관리와 관련된 제반 비용의 부담비율 등을 보다 유연하게 개선하여야 한다. 본 연구는 정부출연연구소에서 민간부문으로의 기술이전만을 고려하여 기술이전의 중요한 요소인 민간부문에 대한 고려가 전혀 없다. 따라서 보다 실질적이고 체계적인 결과를 도출하기 위해 민간부문을 고려한 연구가 진행되어야 한다고 생각한다.

Software product line engineering is a method that prepares for the future reuse and supports to seamless reuse in application development process. Commonality and variability play central roles in all product line development processes. Reusable assets will become core assets by explicitly representing C&V. Indeed, the variabilities that art identified at each phase of core assets development have different levels of abstraction. In the past, these variabilities have been handled in an implicit manner and without distinguishing the characteristics of each core assets. In addition, previous approaches have depended on the experience and intuition of a domain expert to recognize commonality and variability. In this paper, we suggest a 2-dimensional analyzing method that analyzes the variabilities of core assets in software product line. In horizontal analysis process, the variation types are analyzed in requirements, architecture, and component that are produced at each phase of development process. In vertical analysis process, variations are analyzed in different abstract levels, in which the region of commonality is identified and the variation points are refined. By this method, the traceability of variations between core assets will be possible and core assets can be reused seamlessly.

Part-of-Speech (POS) tagged corpus is a collection of electronic text in which each word is annotated with a tag as the corresponding POS and is widely used for various training data for natural language processing. The training data generally assumes that there are no errors, but in reality they include various types of errors, which cause performance degradation of systems trained using the data. To alleviate this problem, we propose a novel method for detecting errors in the existing POS tagged corpus using the classifier of XGBoost and cross-validation as evaluation techniques. We first train a classifier of a POS tagger using the POS-tagged corpus with some errors and then detect errors from the POS-tagged corpus using cross-validation, but the classifier cannot detect errors because there is no training data for detecting POS tagged errors. We thus detect errors by comparing the outputs (probabilities of POS) of the classifier, adjusting hyperparameters. The hyperparameters is estimated by a small scale error-tagged corpus, in which text is sampled from a POS-tagged corpus and which is marked up POS errors by experts. In this paper, we use recall and precision as evaluation metrics which are widely used in information retrieval. We have shown that the proposed method is valid by comparing two distributions of the sample (the error-tagged corpus) and the population (the POS-tagged corpus) because all detected errors cannot be checked. In the near future, we will apply the proposed method to a dependency tree-tagged corpus and a semantic role tagged corpus.

The government announced a plan for fund support to the enterprises with high possibility of recovery and early restructuring for the enterprises with low recovery by objectifying credit assessment system. Such announcement of government could be extended to restructuring risk of middle standing enterprises with low financial soundness by establishing the basis to prepare prompt restructuring by reinforcing the basis for restructuring through capital market. This research analyzed financial soundness based on the financial evaluation of bank by selecting 10 middle standing construction companies which focused on housing business in 2019, based on such analysis result, it was confirmed that there was a high possibility of restructuring risk. This research determined that there would be a decrease in growth rate of construction industry on the whole in 2020 due to fall of economic growth rate and reinforced real estate regulation, accordingly, there's a big possibility for middle standing construction companies with paid-in capital ratio due to its low possibility of maintenance of stable credit rating. This research established KCSI assessment model by utilizing the material of a reliable research institute in order for middle standing construction companies to evade restructuring risk, and indicated risk ratio differentiated per each item through a working-level expert survey. Such research result could suggest credit risk reduction method to middle standing construction company management staffs, and prepare a basis to evade restructuring risk.

In Korea, most of the locations of the cemeteries and burial vault are in forest lands. The utilization of forest land for this particular purpose is very inefficent and considered to be a serious problem. National government (Forest Service), local governments (Incheon city), and religious corporation (eunhoe Temple) are creating new burial methods to solve the inefficiency in forest utilization. In this study, awareness of Koreans and Japaneses on tree burial problems were compared. Based from the results of the survey, more than 80% of the respondents are aware of the problems. However, the burial culture in Korea still has many problems. Operation and management of tree burial is not being done by experts and sufficient information regarding to this type of burial still needs to developed. To solve these problems, eco-friendly burial, which is considered as new funeral culture, is now being created. In the case of Ichinoseki City in Iwate prefecture in Japan, improving the residential environment greatly affected the tree burial practices. This town was chosen for this study due to its characteristics of being a tourism area which greatly affecting the economy of this town. Another study site of this study was located in Sangju city. The changing social environement and the perception of the people regarding on the services being provided to the people were examined thru questionnaire survey. Specifically, this study analyzed the practices and beliefs of the people regarding the tree burial culture.

This study aims to analyze various issues and problems in the implementation process of cultural impact assessment in 2016. As a result of the analysis, it is found that the evaluation index of the cultural impact assessment is difficult to understand, and the referring data and materials in the evaluation planning phase in the process of the cultural impact assessment are deficient, and the evaluation planning is based on surveys rather than various methods. And there are some problems with evaluation scales and weighting, and they are focused on the evaluation itself rather than the feedback of the evaluation results. Therefore, this study suggests that, in the evaluation planning phase, the different methods of comparing the evaluation results according to the project execution, the project progress, and the completion time of the project should be adopted, and the project manager and the evaluation group participate developing the evaluation indicators together, and methodology for identifying causal relationship such as system dynamics will be adopted. In the stage of evaluation, it is necessary to introduce various methodology such as diverse residents participation, abundant case study, application of quantitative methodology, and the utilization of expert evaluation teams. In the evaluation feedback stage, it is necessary to provide thorough consulting based on the evaluation results.

Oriental Diagnosis System(ODS) is an artificial intelligence program that utilize entered diagnosis knowledge, determine patient's disease and decide right medicine. The purpose of this study is to find a correlation between pattern Identification in Korean medicine and each sasang types(So-Yang, So-Eum and Tae-Eum) by analyzing ODS diagnosis result. Eventually our study secure availability of using ODS program at clinical training or developing diagnosis program. Subject of this study is 32 students participating in Sasang medical practice(12 subjects were So-Yang, 7 subjects were So-Eum, and 13 subjects were Tae-Eum). We analyze subject's clinical practice result reports by using ODS program and obtained result about pattern Identification. We used SPSS statistics 23 in analyzing the differences of the scores of Eight Principle Pattern Identification, Qi-Blood Pattern Identification, Bing-xie Pattern Identification, and Visceral Pattern Identification in each Sasang types (So-Yang, So-Eum, Tae-Eum). In the case of Heat-moisture, Tae-Eum showed higher score than So-Eum, but So-Yang showed no difference from the other two Sasang types(p<0.05). And in the case of Food-accumulation, Tae-Eum and So-Yang showed significantly higher score than So-Eum(p<0.05). It is hard to generalize the result because subject of this study was not enough. However, we explained correlation between pattern Identification in korean medicine and each sasang types based on quantifiable and objective evidence system. Therefore use of ODS program in student clinical practice training help to understand the relationship and correlation between different pattern Identification and will help standardization of clinical practice education.

The appropriateness of introducing blockchain technology into food safety management systems was evaluated by conducting a survey of experts on the effectiveness and constraint evaluation indicators, and a portfolio analysis was conducted to set the priorities of blockchain application. The food safety management activities considered in this study were issuing documents on food import/export, food hygiene rating scheme, civil complaint management in the food sector, food- related certification, risk information management, and food traceability systems. The sectors that can be expected to be effective in the introduction of blockchain technology were food- related certification, food hygiene rating scheme, risk information management, and issuing documents on food import/export. In the case of food traceability systems and civil complaint management, the introduction of blockchain technology was not recommended due to ineffectiveness. From the evaluation of the constraints (e.g., technical limits, cost, legal amendment, personal information disclosure, timeliness, and ease of connection) to be overcome when introducing blockchain into food safety management, it was found that there are more than average constraints in all six areas. In particular, the food traceability system was evaluated to have the most constraints. Issuing documents on food import/export is very effective with the introduction of blockchain technology, but due to high cost and legal restrictions, it is necessary to improve the institutional system in order to introduce blockchain. Among the evaluation sectors, food- related certification, food hygiene rating scheme, and risk information management on foods were suitable for preferentially adopting blockchain technology since these areas might experience greatly improved reliability and transparency through the introduction of blockchain, with relatively low constraints.

In this paper, we propose a synchronized playback method of 3D reference model and video by extracting golf swing information from learner's golf video to precisely compare and analyze each motion in each position and time in the golf swing, and present the implementation result. In order to synchronize the 3D model with the learner's swing video, the learner's golf swing movie is first photographed and relative time information is extracted from the photographed video according to the position of the golf club from the address posture to the finishing posture. Through applying time information from learners' swing video to a 3D reference model that rigs the motion information of a pro-golfer's captured swing motion at 120 frames per second through high-quality motion capture equipment into a 3D model and by synchronizing the 3D reference model with the learner's swing video, the learner can correct or learn his / her posture by precisely comparing his or her posture with the reference model at each position of the golf swing. Synchronized playback can be used to improve the functionality of manually adjusting system for comparing and analyzing the reference model and learner's golf swing. Except for the part where the image processing technology that detects each position of the golf posture is applied, It is expected that the method of automatically extracting the time information of each location from the video and of synchronized playback can be extended to general life sports field.

Despite the diverse system development and improvement initiatives that have been created to improve the environments of child birth and nurturing, the birth rate in Korean society remains low. Some minor teenage single parents give birth and raise children. Teenage single parents are supported by the Single-Parent Family Support Act, but some of their needs are still not being addressed. As each single parent has different backgrounds and socioeconomic characteristics, an investigation is required for developing differentiated support in which they will be considered both parents and children. Therefore, this study identifies the unique problems encountered by teenage parents, focuses on single mothers giving birth, and explores measures that teenage parents can use to be independent members of civil society. Three suggestions are presented for the period from pregnancy and childbearing to parenting. First, there should be an education support plan that will enable them to finish tertiary education, and parent education. Second, measures should be created to initiate a change in direction in indifferent biological(real) fathers: these should enlighten and help them participate in rearing their children. Third, in addition to improvements of the current systems only targeting single parent-family support, which will help differentiate teenage parent support from adolescent single parent-family support, assistance should be given for teenage single parents to grow as a Subject of Rights through tailored independent support programs.
