OASIS(Oriental Medicine Advanced Searching Integrated System) provides the information on research articles of Korean Medicine. This study aims to propose an article construction system that can manage massive metadata of articles efficiently by analyzing its repetitive input procedure. Since the articles are provided in the form of public data that can used by everyone, metadata of the articles should be constructed correctly. In the past, the metadata had been entered in three steps. Thus, it takes a lot of time to input the metadata, and many errors occur during the steps. To solve these problems, we in this paper developed an article construction system that the metadata can be corrected by preventing users’ input mistakes. After a PDF file is uploaded in this system, the publication information of the journal is extracted automatically from the file name of the PDF. Then, other metadata is entered and metadata input of the article is completed. By using the article construction system, absolute task time for constructing the information of article database was reduced and metadata input errors were prevented. In the future, we will demonstrate the performance of our system through empirical research so that other related systems can utilize the method of this system.

The production of monographs for herbal medicine resources has become active in numerous countries after the Nagoya Protocol has taken effect since 2014. We have to accumulate accurate information as a country of biological, genetic resources. The limiting factor that occurs at a field where medical herbs are collected for storing data is that there are sometimes areas where Internet communication is not possible. It is also not possible to search for data that we have already built. To solve these problems, we developed a new supporting tool on mobile which based on Android native application. The herb experts can record accurate information in any environment with this tool such as deep mountains, remote islands, and Mongolia. And we can find the information on plant specimens and origins of herbal medicines that we already have. We have detailed explanations of the mobile apps developed in this paper so that many experts can utilize the system in the future.

기업 지배구조와 사회적책임활동이 이익조정에 미치는 영향

장윤지,홍철규 한국공인회계사회 2020 회계·세무와 감사 연구 Vol.62 No.3

The purpose of this study is to analyze the relationship between corporate social responsibility, governance, and earnings management. This paper first analyzes the effect of governance and social responsibility on earnings management and then analyzes the influence of corporate social responsibility on relationship between corporate governance and earnings management. The sample of the study consists of domestic companies whose ESG(Environment, Social, Governance) ratings were announced by Korea Corporate Governance Service from 2011 to 2018. Discretionary accruals are estimated using the modified Jones model, and major hypotheses are tested through multivariate regression analysis. The main results are as follows. First, firms with good corporate social responsibility activities were more likely engaged in earnings management and tended to report earnings downward. Second, the better the corporate governance structure, the higher the level of social responsibility activities. It was also shown that companies with good corporate governance structure tended to report earnings upward, which was not statistically significant, though. Third, companies with good governance structure were more likely to participate in earnings management and tended to report profits downwards in comparison with those with bad governance structure when corporate social responsibility activities were bad. In an additional analysis of surplus and deficit firms, the results show the same phenomenon in surplus firms, but not in deficit firms. These results show that the relationship between corporate social responsibility, corporate governance, and earnings management is very complex, and that the relationship between corporate governance and earnings management is difficult to fully understand without considering the influence of corporate social responsibility activities. 본 연구는 2011년부터 2018년까지 한국지배구조원에 의해 ESG등급이 발표된 국내 기업들을 대상으로 기업지배구조, 기업사회적책임활동(CSR), 이익조정 간의 관계에 대해서 분석하고자 한다. 수정 Jones모형을 이용하여 재량적 발생액을 추정하였으며, 다변량 회귀분석을 통해 주요 가설들을 검증하였다. CSR과 이익조정의 관계에 대해 기존 연구들은 상반된 결과들을 보여주고 있는데, 이는 CSR 수행동기와 밀접히 관련된 것으로 판단된다. 지배구조의 경우에는 지배구조가 우수한 경우 대체로 이익조정이 감소한다는 것이 기존 해외연구의 결과이다. 그러나 국내연구에서는 지배구조가 이익조정에 미치는 영향에 관해 통일되지 않은 다양한 연구결과들이 제시되어 있다. 이는 우리나라에서는 관련 제도가 지배구조 선진국에 비해 비교적 형식적으로 운영되고 있기 때문인 것으로 판단되며, 이에 따라 지배구조가 이익조정에 미치는 영향에 관해 추가적인 분석이 요구된다. 아울러, CSR과 지배구조가 이익조정에 미치는 영향이나 상호관계를 각각 독립적으로 검토하는 기존 연구들은 이들 간의 상호작용이 이익조정에 미치는 영향을 고려하지 않는다는 점에서 큰 한계를 지닌다. 본 연구에서는 이들 간의 상호작용이 이익조정에 미치는 영향을 분석함으로써 CSR, 지배구조, 이익조정의 복합적인 관계에 대한 이해를 제고하고자 한다. 또한, 기존 연구와 달리, 이익조정의 측정치로서 재량적 발생액 자체와 절대치를 모두 사용함으로써, 이익조정의 규모와 방향 및 그 의미에 대해 보다 포괄적이고 명확한 이해를 제공할 수 있을 것으로 기대된다. 주요 분석 결과는 다음과 같다. 첫째, CSR 수준이 높은 기업은 나쁜 기업에 비해 이익조정의 규모가 크며, 하향으로 이익을 조정하는 것으로 나타났다. 둘째, 기업지배구조가 좋은 기업은 나쁜 기업에 비해 이익조정의 규모가 크고 상향으로 조정하는 것으로 나타났지만 통계적으로 유의하지는 않았다. 셋째, 지배구조가 CSR과 이익조정의 관계에 미치는 영향은 CSR 수준에 따라 다른 것으로 나타났다. CSR 수준이 낮은 기업 중에서 지배구조가 좋은 기업은 나쁜 기업에 비해 이익조정의 크기가 더 큰 것으로 나타났으나, 이익을 더 낮추는 하향의 이익조정 경향이 있는 것으로 나타난 반면, CSR 수준이 높은 기업 중에서 지배구조가 좋은 기업은 나쁜 기업에 비해 이익조정의 크기가 더 작은 것으로 나타났으며, 이익은 더 높게 보고하는 경향이 있는 것으로 나타났다. 추가적으로, 강건성 검증에서도 유사한 결과가 나타났다. 흑자기업과 적자기업을 별도로 분석한 결과에서는 흑자기업에서는 동일한 현상을 발견했지만 적자기업에서는 유의한 관계를 발견하지 못했다.

Thanks to the development of medical technology and changes in atmosphere in pursuit of a healthy life, the names of medicinal herbs have become approachable, and public interest has increased. On the other hand, the production of monographs for herbal medicine resources has become active in numerous countries after the Nagoya Protocol has taken effect. This study is about the establishment of a Korean herbal medicine resource monograph that provides herbal medicine resource information service that can be used not only by professionals but also by the general public. Prior to compiling the monograph of 478 medicinal herbs available domestically, the monograph of a sample herb, "Scutellaria baicalensis Georgi(黃芩)" and an establishment guidebook were proposed to 252 experts, and a demand survey was conducted from the perspective of users. Expert counsel was also sought for analysis. If the degree of completion is heightened by applying the collected opinions and supplementing the data for the commencement of service in the second half of the year, the best Korean herbal medicine resource information service with high public confidence is expected to be developed.

People's interest in using Korean medicine and herbal medicine has increased. In order to promote the stable use of medicinal herbs and prepare for the effectuation of the Nagoya protocol, we developed a system to search for specialized information on 478 medicinal herbs. 58 databases have been established based on the medicines issued by the Food and Drug Administration. It contains nine major items including the “Name”, “Medicinal property”, “Origin”, “Distinction”, “Physico-chemistry”, “In vivo & In vitro”, “Clinical application”, “Production and processing”, and “Patent”. The schema is designed to search for information. And we developed a search system for use in the OASIS. Administrator pages for modification and management of database are developed and operated separately. The findings of this study allow for easier navigation of proven professional information. In response to the effectuation of the Nagoya Protocol, each country needs to secure a database of biological resources. Thus, it is considered that it will serve as a foundation for the construction of data for the national economy.

The purpose of this study was to examine the perceptual priming effect using the analogue trauma paradigm. This study also aimed to determine whether anxiety responses in individuals experiencing analogue trauma were triggered by stimuli specific to trauma or general threats. A total of 103 university students with a score of 10 or lower on the Posttraumatic Diagnostic Scale (PDS) and a score of 23 or lower on the Beck Depression Inventory (BDI) were included. Participants viewed a distressing film as an analogue for a traumatic event, after which they completed a perceptual identification task using words or pictures. The results of this study can be summarized as follows: First, the response rates were significantly faster to traumarelated stimuli than to general threat stimuli. Second, unlike the words-task, the response rates were significantly faster to trauma-related stimuli than to general threat stimuli in the pictures-task. To sum up, this study demonstrated that trauma survivors showed perceptual priming of traumatic stimuli when exposed to perceptual cues related to trauma. The present findings suggest that interventions for individuals who experience posttraumatic stress symptoms should be aimed at reconstructing perceptual information about trauma-related stimuli. Finally, the limitations of this study were discussed along with suggestions for further research.

This study aims to propose a big data center to construct the information on medicinal biological resources and provide the infrastructure to open and share them. The information on the medicinal biological resources consists of basic data such as effects, treatments, and warnings of medicinal biological resources, biochemical data such as chemical compounds of medicinal materials and mappings among compounds and targets, and utilization data such as locations and times of discovery of medicinal resources. In order to ensure the data compatibility, all data was constructed in an open format. The bigdata of medicinal biological resources are opened and searched on our bigdata center (http://kmbigdata.kr) which is constructed based on CKAN. Our bigdata center provides medicinal biological resource data in CSV and RDF file format along with their metadata in DCAT format. Moreover, medicinal biological resource data are provided to the forest bigdata platform using ESB. Therefore, our data can be obtained on the forest big data exchange (http://bigdata-forest.kr). By using the bigdata center and forest big data exchange, it is expected that domain experts and the publics will be able to use the accurate and useful data on medicinal biological resources for the health care and biotechnology companies will be able to search our data to make products such as new drugs and functional foods.

Crocin 성분들의 명명법과 화학 구조 비교

장윤지,김상균 한약정보연구회 2023 한약정보연구회지 Vol.11 No.2

Crocins are a group of water-soluble carotenoids that are either monoglycosyl, diglycosyl, or triglycosyl polyene esters of crocetin and are abundant in both Crocus (Crocus sativus L.) and Gardeniae Fructus (Gardenia jasminoides Ellis). Several crocins have been identified in these two herbs, known as crocins 1-5; their structures are similar, with the differences lying in their glycosyl types and quantities. Recent papers and PubChem databases reveal compounds with the same chemical name but different types of sugars bound to the crocetin aglycone. In this paper, we compare and analyze the names and chemical structure characteristics of crocins defined in research papers and the PubChem database. Future studies on crocins should refer to these characteristics for identification and utilization.
