This study is aiming at improving the Environmental Conservation Value Assessment Map(ECVAM) of National Land in Korea. The ECVAM items are composed of legal and environmental/ecological assessments. A popular method applied to ECVAM is an overlay environmental/ecological assessment items. The purpose of this study is to offer complementary items of the ECVAM by examining assessment items. In this study we assessed the ECVAM by five methods. Method 1 is Grade 1 areas of each administrative district; Method 2 is comparing overlapped areas of each assessment items Grade 1, 2 and permission of each assessment items duplication; Method 3 is Grade 1, 2 areas by only singular assessment items; Method 4 is Grade 1 areas only of Method 2; and Method 5 is Grade 2 areas only of Method 2. Method 1 showed Seoul and other metropolitan cities revealed a large proportion of Grade I regions by the legal assessment items. Gang won-Do, showed a large proportion of Grade I regions by the environmental/ecological assessment item. Method 2 showed 93.4% of diameter Grade II(standard for stability); forest diameter item accounted for 99.9% by Method 3, Method 4 showed 95.7% of forest diameter, and forest density accounted for 66.4% by Method 5. This study contributes to reduce the complexity in the process of manufacturing ECVAM of National Land, and to raise the flexibility in the process of managing and updating this map.

In this study investigated the effect of the chemical injection ratio on the drying rate of sewage sludge. Then the economic efficiency was evaluated by comparing the results of the NIR(near infrared ray) and microwave drying rate test. The near infrared ray device showed drying speed of 31.9 %, 28.1 %, and 27.1 % at polymer dose ratio of 8 %, 10 %, and 12 %, respectively. Compared to 8 % polymer dose ratio, polymer dose ratio of 10 % and 12 % showed differences of 8.0 % and 13.6 % respectively, suggesting that drying efficiency decreased as polymer dose ratio increased. The microwave device showed drying speed of 26.2 %, 24.3 %, 21.3 % at polymer dose ratio of 8 %, 10 %, and 12 %, respectively. Compared to 8 % polymer dose ratio, polymer dose ratio of 10 % and 12 % showed differences of 5.2 % and 13.4 % respectively, suggesting that drying efficiency decreased as polymer dose ratio increased. Drying evaluation estimated the treatment cost of near infrared ray device at optimal dose ratio(6 %) was 35,591 won/ton while that of actual dose ratio(8 %) was 38,928 won/ton. Drying evaluation estimated treatment cost of microwave device at optimal polymer dose ratio(6 %) and at 8 % to be 16,683 won/ton and 18,352 won/ton, respectively.

The purpose of this study was to find out the successful factors of the policy of military robot by analyzing the cases of the US and the ROK using the comparative historical analysis from the perspective of historical institutionalism. Additionally, this study was to figure out how these implications of case studies affect to develop the successful policy of military robot of the ROK in the future. This study focused on the period from 1898 to 2013. Historically, the US has developed and operated many kinds of military robots, but the ROK has developed and operated only a few kinds of military robots. Also, the US has acquired and exported many kinds of military robots that they have developed, but the ROK has acquired only a few kinds of military robots that the ROK has developed and has not exported the robots. The basic framework of the study has been established by setting out the influential factors from various theories of the policy of military robot. Generally, the first influential factor which has been identified was the development capability of military robots by robot developers, the second was the requirement plan and the verification capability of military robot by the army, the third was the countermeasure against the opposite public opinions to acquire and operate military robots, the fourth was the support of the government to acquire and export military robots that he has developed, the fifth was the law and regulation concerning military robot. This study has found that there were successful factors with complex interconnection. Built from these factors, the implications can be applied in the light of our task on the development of the policy of the military robot. In conclusion, the results of this study are as follows: Firstly, it is necessary for robot developers to develop military robots to satisfy military user``s need with more challenge and effort, before they ask the sufficient development cost of the government and the ROK Armed Forces. Instead of wasting time, efforts, and budgets by redundantly developing military robots, robot developers should also keep a close cooperation with one another to achieve win-win and endeavor to reduce the development period and cost. In addition, they need to find out not only the reason why the ROK Armed Forces and the UN are against the acquisition of domestic military robots but also the solutions for it and should prevent the military robot technology and secrets from being leaked overseas. Secondly, the ROK Armed Forces should let the robot developers know the requirement of the military robots and the user``s need as much as possible by forming the personnel and the organization responsible for the requirement plan of military robots. Furthermore, the ROK Armed Forces has to not only secure the budgets for performing the combat experiments designed suitably for the ROK military operation environment with a variety of domestic military robots but also make its personnel including the chief of staff promote the publicity campaign concerning the necessity of the robots. Moreover, the ROK Armed Forces should find out why the ROK Armed Forces and the UN object to the acquisition of the robots developed in Korea and set up the countermeasures against the opposite public opinions. Thirdly, the government should consistently set up the policies that ensure purchasing domestic military robots instead of foreign ones, while focusing a full support only on the military robots which passed the combat experiment. Moreover, the government should enacts related policies and promote the publicity campaign of these robots.

The purpose of this study was carried out an epidemiological survey on the prevalence rate of the canine heartworms in Seoul City and the districts of Pa-Ju, Seong-Nam and Po-Chon in Kyonggi province of Korea from September 1994 to the end of September 1995. The blood samples from 292 male and 193 female dogs (pet, 363 ; fighting dogs, 60 ; working dogs, 62) were examined for the adult heartworms cuticle antibodies using the enzyme-linked immunosorbent assay (ELSA) kits. The test was designed to detect the antibodies of the host against the specific cuticle antigens produced with the adult heartworms.

단수가격의 효과

조윤희(Jo, Yunhee),이원제(Lee, Won Jae),이성근(Yi, Seong Keun) 한국상품학회 2009 商品學硏究 Vol.27 No.3

단수가격에 관한 연구가 많이 이루어진 미국의 화폐 단위는 달러($)와 센트(¢), 두 가지로 표시한다. 하지만 우리나라의 경우 원(\) 단위가 유일하며, 1원 단위는 일반적인 현금 거래에서 통용되지 않는 화폐단위이다. 이처럼 기본적인 화폐 단위에 대한 차이가 있기 때문에 미국의 단수가격의 효과에 관한 실험 결과를 우리나라의 가격 연구에 그대로 받아들일 수 없다. 또한 단수가격의 효과에 관한 기존 연구들은 일반적으로 관여도가 낮은 저가격 제품을 대상으로 하고 있다. 따라서 우리나라의 경우에도 저가격 제품일 때 소비자의 가격에 대한 태도가 긍정적인지에 관한 연구와, 저가격 제품과 비교해 고가격 제품에서 단수가격을 사용하는 경우 그 효과가 달라지는지에 관한 연구를 하고자 한다. 실험 결과, 저가격 제품에서는 선행 연구에서처럼 단수가격에 대한 소비자의 태도가 정수 가격에 대한 소비자의 태도 보다 긍정적이었지만, 고가격 제품에서는 단수가격에 대한 소비자의 태도가 정수가격에 대한 소비자의 태도 보다 부정적으로 나타남을 증명하였다. 그러나 브랜드 인지도와 소비자의 가격에 대한 태도는 서로 상관이 없는 것으로 나타났다. Odd-price effect has been mainly applied to the goods with lower level price because consumers do not process the price information elaborately in the low involvement situation. Additionally as consumers have a tendency to process the price information from the left to the right digit, they perceive the goods with odd-price as much cheaper. The meaning of odd-price has some difference between U.S. and Korea. Usually odd-price in U.S. means 9-ending price. In Korea, odd-price should not be 9-ending price because unit "won" in price is perceived as a very small amount, the price strategy with 9-ending can not used. Thus, the odd-price should be the price ending at least 10 won. For that reason we can't apply the same concept used in U.S. to the Korean market. Based on the previous studies, I was concerned that odd-price policy still had an effect on the consumer attitude in Korean currency and that it could be applied to the good sith high level price. Additionally I checked how the brand moderates the effect of odd-price because brand could give some trust for the justification of the strategy.

본 연구에서는 인공지능 모델에 따른 한국 프로야구의 승패 예측 분석에 관한 연구를 했다. 승리할 팀과 해당 팀의 최종 리그 순위를 예측했고, 사용자의 편의를 위해 웹사이트도 구축했다. 각 1·3·5이닝 별로 가장 정확도가 높으면서도 오차가 적은 모델을 최적 모델로 선정해 승·패 결과를 예측했고, 이를 토대로 순위표를 작성했다. 결과표는 2020년 개막인 5월 5일부터 8월 30일까지의 예측 결과를 바탕으로 작성했다. 기아타이거즈가 아닌 다른 구단끼리의 경기는 실제 결과를 사용했다. 머신러닝 모델은 KNN과 AdaBoost가 최적 모델로 선정되었으며, 실제 순위와 비교해 본 결과, 경기가 진행될수록, 예측 결과의 순위 오차가 점점 작아지는 것을 확인했다. 딥러닝 모델은 89%의 정확도를 기록했고, 머신러닝 모델과 마찬가지로 경기를 진행할수록 예측 결과 순위 오차가 작아지는 것을 확인했다. 실험 결과는 한국 프로야구 승·패 결과 예측뿐 아니라 다양한 분야에서 사용할 수 있을 것으로 사료된다. 방송국에서 야구 경기를 중계하는 중 이닝별로 인공지능 알고리즘이 예상한 승·패 여부를 중계화면에 띄울 수 있다. 시청자들에게 새로운 흥미를 일으킬 수 있을 것이고, 나아가 구단의 감독들이 이닝마다 데이터를 분석해 경기 중 유동적으로 승리하기 위한 전략을 세울 수 있을 것으로 기대된다. In this study, we conducted a study on the win-loss predicton analysis of korean professional baseball by artificial intelligence models. Based on the model, we predicted the winner as well as each team’s final rank in the league. Additionally, we developed a website for viewers’ understanding. In each game’s first, third, and fifth inning, we analyze to select the best model that performs the highest accuracy and minimizes errors. Based on the result, we generate the rankings. We used the predicted data started from May 5, the season’s opening day, to August 30, 2020 to generate the rankings. In the games which Kia Tigers did not play, however, we used actual games’ results in the data. KNN and AdaBoost selected the most optimized machine learning model. As a result, we observe a decreasing trend of the predicted results’ ranking error as the season progresses. The deep learning model recorded 89% of the model accuracy. It provides the same result of decreasing ranking error trends of the predicted results that we observe in the machine learning model. We estimate that this study’s result applies to future KBO predictions as well as other fields. We expect broadcasting enhancements by posting the predicted winning percentage per inning which is generated by AI algorism. We expect this will bring new interest to the KBO fans. Furthermore, the prediction generated at each inning would provide insights to teams so that they can analyze data and come up with successful strategies.

문화공연 청중의 문화적 취향에 관한 연구

서문식(Suh, Mun-Shik),이샛별(Lee, Sae-Beul),엄성원(Eum, Seong-Won) 한국문화융합학회 2020 문화와 융합 Vol.42 No.4

The purpose of this study is to examine how cultural performance audiences’ cultural tastes are differentiated and how they appear, and to present a cultural taste scale. As a scholarly predecessor, Bourdieu’s cultural capitalism, which argued for the existence of a significant relationship between cultural taste and class, highlighted the necessity of a new perspective on cultural tastes and their classification criteria that would be applicable to modern-day Korean society. In order to facilitate a concrete discussion on that subject, an audience that watched a cultural performance within the last 6 months was surveyed, and an interview with the audience (cultural experts and the general audience) was conducted. A questionnaire was developed, revised, and then used. The SPSS 23.0 statistical package program was used to conduct reliability and validity analyses, including a frequency analysis. The study’s demographic and viewing characteristics were as follows. There were 88 women (57.1%) and 66 men (42.9%). Respondents’ ages ranged from 20 to 29 years old, with 66 people (42.9%) in their twenties, and from 30 to 39 years old, with 39 people (25.3%) in their thirties. The respondents with the most advanced educational background were 131 students (85.1%) who had either graduated from or were attending university at the time of the study. With regard to average monthly income, there were 44 people (28.6%) who made less than 3~5 million won. For occupation, the highest result was 58 students (37.7%). Meanwhile, with regard to marital status, there were 102 single people (66.2%) and 52 married people (33.8%). For favorite genre, the highest result was 39 people (25.3%) who reported plays as their favorite genre. Moreover, companions had the highest response rate, with 69 lovers (44.8%). With regard to the ticket collection method, there were 134 people (87.0%), most of whom paid a fee. Finally, visit frequency was the highest among 82 people (53.2%) who visited more than 6 times. The cultural tastes examined in this study were: 1) palatable, 2) sensitive, 3) nostalgic, 4) fusion/complexity, 5) essential, 6) pleasure, 7) educational, and 8) popular. Thus, cultural preference was found to be composed of these eight elements. On the basis of these results, this study suggested a cultural taste scale that is applicable to modern-day Korean society. The study also indicated theoretical and practical implications for the field of culture and arts management as well as directions for further research. 이 연구는 문화공연 청중의 문화적 취향은 어떻게 분화(구성)될 수 있는지를 탐색적으로 살펴보는 데에 목적이 있다. 이를 위한 선행으로 문화적 취향과 계급 간의 유의미한 관계를 주장한 Bourdieu의 문화 자본론을 논의하며, 오늘날 새로운 관점에서 문화적 취향 분류 기준이 필요함을 제안하였다. 최근 6개월 이내에 문화공연을 관람한 청중을 대상으로 설문 조사를 진행하였으며, 이는 문화적 취향과 분류에 관한 논의들이 매우 부족하여, 선행연구 및 사전 조사(인터뷰)를 진행하여 수정 및 개발된 설문 문항을 사용하였다. 그런 다음, SPSS 23.0 통계패키지프로그램을 활용하여 분석을 진행하였다. 이 연구에서 조사된 문화공연 청중의 문화적 취향은 1)기호성 취향, 2)감수성 취향, 3)향수성 취향, 4)융·복합성 취향, 5)본질성 취향, 6)쾌락성 취향, 7)교육성 취향, 8)대중성 취향의 8가지 요인으로 구성될 수 있음을 알 수 있었다. 이를 바탕으로, 다음과 같은 시사점을 제안하였다. 오늘날, 문화공연에 관한 이론적 및 실무적 업계에서는 추상적인 만족도 조사보다는 관객 성향, 공연 취향 등 구체적인 조사를 통한 공연제작과 기획이 필요하다. 감정을 공유하고, 감정을 전이하며, 스토리에 공감할 수 있는 공연 개발과 관람 환경 조성이 필요하며, 문화공연 서비스를 제공하는 예술가나 행정가의 역할이 예술성이나 상품성에, 그리고 수익성에 편향되지 말아야 할 것이다. 또한, 현대사회를 살아가고 있는 사람들에게 지친 마음과 고갈된 감정을 치유하기 위한 공연 개발이 필요하다. 공연 업계에서는 급변하는 콘텐츠의 특성을 이해하고, 장르 간 융·복합, 기술과 융·복합 공연 개발 노력이 필요하다. 그러나 많은 것들이 융·복합되고 창작문화공연들이 증가한다고 할지라도, 과하지 않은, 기본기에 충실한, 작가의 의도가 왜곡되지 않은, 원작과 크게 변형되지 않은 공연 개발이 필요하다. 문화라는 정형적인 틀과 관점에서 벗어나 예술가를 포함한 매개자의 노력과 참신한 아이디어, 표현력, 일상의 재미와 즐거움, 색다른 경험을 제공하는 공연이 필요하다. 문화공연은 그 특성상 ‘문화’라는 요소의 이해를 필요토록 하기에 학습과 기량에 도움을 주는 교육적 콘텐츠 개발과 공연에 관한 정보를 적극적으로 홍보하고 마케팅을 해야 하며, 전문적인 작품해설, 공연 및 배우의 특징 설명, 공연 관련 자료, 배우와 관객의 소통 시간 등을 제공하여, 수동적 관람이 아니라 적극적이며 양방향의 공연문화로 자리 잡을 수 있도록 환경을 만들어야 할 것이다. 상품적으로 장르적으로 문화적으로 접근이 쉬운 공연이 제작이 필요할 것이다.

Objectives : The purpose of this study is to explore the trends of Korean medical study on stress in the industrial worker. Methods : We received numbers of the studies about stress in the industrial worker from 6 Korean web databases, using key words such as ‘Industry AND Stress’, ‘Oriental medicine AND Stress’, ‘Worker AND Stress’, ‘Workplace AND Stress’. We received 12 research papers and they were analyzed and the journals, the authors, the contents of 3 classification of those research papers. Results : Among them, we had 6 reviews of Dept. of preventive medicine and Dept. of third medicine, college of Korean Medicine, Won-kwang University, and the rest of them were 6 reviews. We had 4 reviews of Korean Journal of Oriental Preventive Medical Society, 2 reviews of the Journal of Traditional Korean Medicine, 2 reviews of Journal of Oriental Neuropsychiatry and so on. According to the contents of reviews, we had 7 reviews of correlation of industrial worker and stress, 4 reviews of cause on the industrial worker’s stress and 1 case report. Conclusions : We reviewed the trends of Korean medical study on stress in the industrial worker. The stress in the industrial workers were related with the type of occupation, social psychology, drinking, smoking, the satisfaction of job, the harmony of organization.And we knew that the musculoskeletal pain was related to the industrial worker’s stress. In the future, abundant case studies, follow-up trials and RCTs should be done about the industrial worker’s stress.
