Objectives: This study was aimed to analyze the correlation of clinical characteristics of cancer patients treated with Korean Medicine and their natural killer cell activity (NKA). Methods: The medical records of 52 cancer patients who conducted NKA test at Cheonan Korean Medicine Hospital of Daejeon University from March 2016 to May 2018 were reviewed. NKA was determined at Seegene Medical institute using NK Vue Gold(R) kit, evaluating activated $IFN-{\gamma}$ by enzyme immunoassay after incubation of whole blood. Careful investigations were conducted by categorizing the patients by their sex, origin, stage, ECOG scale, and conventional treatment type. We used data from the medical records and statistical analysis using SPSS 25.0 V. Results: The average NKA of all patients was $623.1{\pm}722.0pg/mL$. The NKA value was higher for females than for males. No correlation was evident between age and NKA, but patients aged over 70 years had the lowest NKA average result. Stage III and IV patients showed clearly lower NKA values when compared to stage I and II patients. NKA and ECOG scale values showed no evident relationship. Conclusions: This study presented the characteristics of NKA in cancer patients treated with Korean medicine. The NKA result differed by gender and stage. Based on these findings, further study is needed regarding the clinical meaning of NKA.

Granuloma annulare (GA) is a common non-infectious granulomatous disease. Generalized GA is the second most common variant of GA. It is often associated with recalcitrant disease progression despite treatment. The lesion of generalized GA typically presents widespread papules that coalesce to form annular plaques over the whole body. We report a case of a patient with disseminated papules and coalescing annular plaques, primarily involving the intertriginous area and mimicking tinea corporis or cruris. Histopathological findings confirmed the lesion as GA. This case underscored the unusual clinical presentation of generalized GA. A case of GA localized to the intertriginous area has rarely been reported. Given the recalcitrant nature of the disease, dermatologists should consider generalized GA as a differential diagnosis in patients with an annular lesion involving the intertriginous area. Thus, we report this as an atypical case of generalized GA localized to the intertriginous area. (Korean J Dermatol 2021;59(10):797∼800)

북한의 사회주의 경제관리 비교 연구

이가영(Ga-Young Lee) 국민대학교 한반도미래연구원 2022 한반도미래연구 Vol.7 No.1

가계, 기업, 정부의 유인에 의해 이루어지는 생산 및 분배, 유통 및 소비가 사회주의 경제이론에서는 철저한 계획(planning)을 통해 이루어진다. 계획과 함께 사회주의 계획경제의 핵심적인 특징은 국가의 직접적인 관료적 통제(direct bureaucratic control)인데 이것을 북한에서 ‘경제관리’라고 한다. 본 연구에서는 7월 1일 경제관리개선조치가 시행된 2002년부터 2019년까지 김정일 시기와 김정은 시기의 사회주의 경제관리를 비교 연구하였다. 북한 문헌 『경제연구』의 문헌분석과 병행하여 텍스트마이닝을 통한 빈도분석 및 시각화를 하였다. 빈도분석 결과 상위 30개 단어 중에 김정일 시기에만 포함되는 단어는 ‘원칙’, ‘개선’, ‘정치’, ‘체계’, ‘단위’ 등이다. 반면 김정은 시기에만 상위 30위에 포함되는 키워드는 ‘활동’, ‘우리’, ‘주인’, ‘나라’, ‘책임’, ‘근로자’이다. 김정일 시기 경제관리에 있어 ‘원칙과 정치를 중시하고 단위에 따라 체계적으로 관리’를 하였다면, 김정은 시기의 경제관리는 ‘우리가 나라의 주인이 되어 책임을 가지고 활동’하는 것을 강조하고 있다. 김정일 시기 경제관리에서는 ‘계획’, ‘국가’가 상위를 차지하고 있고, 김정은 시기경제관리에서는 ‘발전’, ‘생산’, ‘실현’, ‘기술’의 키워드 빈도가 높다. 이를 통해 전통적 사회주의 계획경제 체제에서 ‘국가가 원칙에 따라 계획하고 개선’하는 경제관리가 ‘과학기술을 기반으로 발전하고 실현’하는 경제관리로 변화하고 있음 키워드 분석을 통해 알 수 있다. Production, distribution, and consumption made by the incentives of households, companies, and governments are carried out through “planning” in socialist economic theory. Along with the plan, a key feature of the socialist economy is the direct bureaucratic control of the state, which is called “economic management” in North Korea. In this study, socialist economic management during the Kim Jong-il period and the Kim Jong-un period was compared and studied from 2002 to 2019, when economic management improvement measures were implemented on July 1. In parallel with the literature analysis of the North Korean literature Economic Research, frequency analysis and visualization were performed through text mining. According to the frequency analysis, among the top 30 words, the words included only in the Kim Jong Il period are ‘principle’, ‘improvement’, ‘politics’, ‘system’, and ‘unit’. On the other hand, the keywords included in the top 30 during Kim Jong Un's time alone are “activity,” “us,” “owner,” “country,” “responsibility,” and “worker.” If “principles and politics were valued and systematically managed according to units” in economic management during the Kim Jong-il period, economic management during the Kim Jong-un period emphasizes that “we become the masters of the country and act with responsibility.” In the economic management of Kim Jong-il period, “plan” and “state” are at the top, and in the economic management of Kim Jong-un period, keywords of “development”, “production”, “realization” and “technology” are frequently used. Through this, it can be seen from keyword analysis that economic management, which “the state plans and improves according to principles” in the traditional socialist planned economy system, is changing to economic management that “develops and realizes based on science and technology.”

This study analyzes the psychological warfare between China and Taiwan, focusing on the pira sprayed across the Taiwan Strait during the Cold War. As is well known, the second Taiwan Strait Crisis, which occurred under the banner of Taiwan"s "Reclam China" and China"s "Liberate Taiwan," is a artillery battle that fired large-scale shells at its opponents, and a psychological war in which various forms of acceleration broadcasts, propaganda broadcasts, and propaganda leaflets were distributed. The two sides carry out an omnidirectional psychological war to promote their ideology and ideas and induce the opponent"s loss and surrender of war. Among them, psychological warfare using propaganda leaflets has been recognized as a very effective psychological warfare method in that it could be exposed to many enemies. In addition, it was frequently used because it has excellent accessibility as a non-institutional medium that can deliver information to ordinary people who cannot access institutional media such as newspapers, magazines, radio, and broadcasting. The purpose of this article is largely divided into two. First, we look at various psychological warfare methods operated by China and Taiwan, and analyze psychological warfare using Pira among them. In particular, it analyzes the association of messages and images contained in beepers produced and distributed by China and Taiwan, and examines the mutual perception underlying them. Second, by deriving the prototypicity of the beepers of both sides and tracking the production purpose and operation logic of the beepers, we would like to understand the negative strategy and Propaganda Campaign of China and Taiwan.

모바일 앱의 시각 인터페이스 디자인에 관한 연구

이가영(Lee, Ga Young),김재현(Kim, Jae Hyun) 한국디지털디자인협의회 2014 디지털디자인학연구 Vol.14 No.1

현대사회 디지털기기의 발전으로 모바일 시장은 많은 변화와 함께 스마트 단말시대를 열었다. 불과 몇 년 사이에 모바일 기기가 대중화되어 현대인들은 앱(app)을 통해 생활정보를 얻기도 하고 여러 가지 다양한 문화활동뿐만 아니라 서비스나, 상품을 사고 파는 전자상거래 또한 활발하게 이용하고 있다. 이처럼 현대 시대의 흐름에 맞춰 국내 대표 인터넷 서점 기업들은 늘어나는 스마트폰 사용자들을 타겟으로 앱을 출시하기 시작했다. 이로 인해 기업들은 물리적인 공간을 이용하지 않고도 수많은 도서들을 효과적으로 유통시킬 수 있게 되었으며 디지털 시대에서 바쁘게 살아가는 소비자들 또한 오프라인 서점을 찾아가 도서를 구매하기보다 시·공간의 제약을 넘어 언제든지 앱을 통해 출판물의 정보를 확인하고 주문해 받아볼 수 있게 되었다. 이런 인터넷 서점앱을 통한 거래는 기업과 소비자 모두에게 효율적으로 시간과, 비용을 절감하는 효과적인 수단이 된다. 하지만 이러한 인터넷 서점의 앱들은 형식적인 도서 정보 전달과 일반적인 고객서비스만 제공하고 있어 인터넷 서점만의 성격을 고려한 맞춤 서비스를 제공하지 못하고 있는 문제점을 지닌다. 이에 본 연구에서는 인터넷 서점 앱의 편의성과 사용성을 높이는데 큰 비중을 차지하고 있는 시각적 인터페이스의 개념과 요소를 파악하고 현재 출시되어 있는 인터넷 서점 앱 디자인에 대해 실증분석을 통해 개선 방안을 모색함과 동시에 더 나아가 앱의 사용자 중심 시각인터페이스 디자인의 방향성을 제시함으로써, 인터넷 서점 앱의 사용성을 높이는데 기여하고자한다. Today an era of smart terminals has begun with a lot of changes in the mobile market, due to the progress of digital devices. In just a few years, mobile devices have become so popular that people get living information, do a variety of cultural activities, and actively take advantage of e-commerce through mobile apps. In line with this trend, major Internet bookstores have started launching apps targeting increasing smartphone users. As a result bookstores have been able to effectively distribute a number of books without the use of physical space, and consumers, who are living busy in the digital age, have also been able to effectively get information about and order books through apps beyond the constraints of time and space rather than through the visit to offline bookstores. These transactions through the bookstore app are effective means of saving time and cost for both businesses and consumers. However, the current bookstore Apps have problems that deliver only perfunctory book information and average customer service without customized services by distinct characteristics of the Internet bookstore. The purpose of this study is to contribute to raising the usability of the bookstore app by identifying the concepts and elements of the visual interface which accounts for a large portion to raise the convenience and usability of the bookstore Apps, looking for ways to improve the design of Apps currently on the market, and further by suggesting the direction of user-centric visual interface design.

한국채택국제회계기준(K-IFRS) 도입이 영업권의 가치관련성에 미치는 영향

이가영 ( Ga-young Lee ) 숙명여자대학교 경제경영연구소 2017 기업경제연구 Vol.45 No.1

본 연구의 목적은 한국채택국제회계기준(이하 K-IFRS라 함) 도입 후 영업권 및 영업권 관련비용의 가치관련성이 변화하였는지를 분석하는 것이다. K-IFRS 도입 이전 회계기준은 영업권을 무형자산으로 계상한 후 20년 이내의 경제적 내용 연수를 정하여 정액법으로 상각하도록 요구한 반면, K-IFRS는 영업권을 내용연수가 비한정적인 자산으로 보아 매년 손상검사를 하도록 하고 있다. 손상검사란 영업권의 회수가능액이 장부 가액에 미달하는 경우 그 차액을 손상차손으로 당기 비용 처리하는 회계처리 절차이다. 그러나 K-IFRS 도입 이후 영업권의 인식 및 손상검사 과정에서 상당한 자의성과 주관성이 개입되어 이익조정의 수단으로 악용될 여지가 있기 때문에 K-IFRS 도입 이후 영업권의 가치관련성이 낮아질 가능성이 존재한다. 기존의 선행연구들은 회계정보의 집합체인 주당순자산 또는 주당순이익을 이용하여 K-IFRS 도입 효과를 분석하고 있는 반면, 본 연구는 K-IFRS에 의해 특히 영향을 많이 받는 개별 계정 과목에 초점을 맞추어 분석하였다는 점에서 선행연구들과 차별성이 있다. 본 연구는 2007년부터 2013년까지 유가증권시장과 코스닥시장에 소속된 12월 결산 제조기업 중에서 상장협의회 데이터베이스에 있는 영업권이 기재된 기업을 대상으로 K-IFRS 도입 이전과 이후의 영업권, 영업권 관련 비용의 가치관련성의 변화 여부를 살펴보았다. 1,216개의 기업-연도를 대상으로 실증분석한 결과는 다음과 같다. 영업권의 가치관련성은 10% 수준에서 유의적인 양(+)의 값을 보였고, K-IFRS가 도입된 이후의 영업권 가치관련성은 음(-)의 값으로 10% 수준에서 유의적인 값이 나타났다. K-IFRS 도입 이후 음(-)의 가치관련성이 있기에 영업권의 가치관련성은 오히려 K-IFRS 도입 후 낮아졌다는 것을 보여준다. 반면에 영업권 관련 비용의 가치관련성은 K-IFRS 도입 전과 후 모두 통계적으로 유의적인 값이 나타나지 않았다. 이 결과는 영업권 관련 비용이 영업권을 상각하는 K-IFRS 도입 이전의 일반회계기준 방법이나 K-IFRS 이후 손상차손만 인식하는 방법 모두 주가와는 관련성이 없다는 것을 의미한다. 그러나 이분산성(heteroscedasticity)을 통제하여 분석한 결과는 영업권과 영업권 관련 비용 모두 주가와의 가치관련성이 없는 것으로 나타났다. 추가적으로 연결재무제표를 대상으로 회귀 분석한 결과도 영업권과 영업권 관련 비용의 가치관련성이 없는 것으로 나타났다. K-IFRS 도입 이후 영업권의 가치관련성이 감소하였다는 결과는 K-IFRS 도입 이후 경영자의 자의적인 판단이나 주관성 개입이 회계정보의 가치를 저하시킬 수도 있음을 시사한다. The purpose of this study is to analayze if there was any change in the value relevance of goodwill and goodwill-releated cost after the adoption of Korean International Financial Reporting Standard (herein K-IFRS). The pre-K-IFRS accounting standards required to put goodwill under the intangible asset and amortize in the straight-line method by setting an economic durable year within 20 years. Whereas the K-IFRS regards goodwill as an asset with nonrestrictive durable terms and requires to perform impairment test every year. If the book value of goodwill is under the recoverable amount, company have to recognize the loss. However, under the K-IFRS, the goodwill recognition and impairment loss inspection process could be largely intervened by arbitrariness and subjectivity to be possibly abused as a means of profit manipulation. Thus, there exists the possibility of reduced value relevance of goodwill after the K-IFRS in place. Preceding literature analyzed the effect of K-IFRS introduction by utilizing the net asset value per share or net income per share, the intensive collection of accounting information. Whereas the present study differentiated itself in focusing on individual accounting titles affected especially more by the K-IFRS. This study investigated companies whose goodwill was registered in the database of the listed companies association from 2007 to 2013 among the manufacturing companies having settlement in December and listed on the stock market in order to examine any change in value relevance of goodwill and goodwill-related cost between the pre-K-IFRS period and post-K-IRFS period. Empirical examination was performed for the total of 1,216 company-years and found as follows; The value relevance of goodwill showed a significant positive number at about 10% level. The post-K-IFRS value relevance of goodwill was negative at the significance level of 10%. The value relevance of goodwill turned negative after the K-IFRS, suggesting that the value relevance of goodwill decreased after the K-IFRS introduction. On the other hand, no statistically significant value was found in the pre/post-K-IFRS value relevance of goodwill-related cost. This finding seems to indicate that there is no relevance between stock prices and goodwill-related cost underboth pre-K-IFRS general accounting practice to amortize goodwill and post-K-IFRS method to recognize only the impairment losses. However, after controlling heteroscedasticity, both goodwill and goodwill-related cost were found to have no value relevance with stock prices. The additional regression analysis on consolidated financial statement also found no value relevance of goodwill and goodwill-related cost. As the value relevance of goodwill was found to decrease after adopting the K-IFRS herein, the study suggests the possibility that, the arbitrary assessment of manager or subjective judgment intervention, after the K-IFRS, could undermine accounting information.
