Influenced by a culture that prefers non-face-to-face activity during the COVID-19 pandemic, chatbot usage is accelerating. Chatbots have been used for various purposes, not only for customer service in businesses and social conversations for fun but also for mental health. Chatbots are a platform where users can easily talk about their depressed moods because anonymity is guaranteed. However, most relevant research has been on social media data, especially Twitter data, and few studies have analyzed the commercially used chatbots data. In this study, we identified the characteristics of depressive discourse in user-chatbot interaction data by analyzing the chats, including the word 'depress,' using the topic modeling algorithm and the text-mining technique. Moreover, we compared its characteristics with those of the depressive moods in the Twitter data. Finally, we draw several design guidelines and suggest avenues for future research based on the study findings.

In textbooks, illustrations are used to easily explain concepts and guide the exploration process. Therefore, the illustration should be presented accurately and easily. However, as a result of analyzing previous studies, it was confirmed that there was no research related to illustration analysis at all in the case of the elementary school 'software education' unit. Therefore, among the six practical textbooks developed according to the 2015 revised curriculum, the illustration of the 'software education' unit was analyzed in terms of type, function, and use, and provided guidelines for the adoption of textbooks, curriculum research, and next textbook development. As a result of analyzing six practical textbooks, all textbooks used more than one illustration per page, and the types of illustrations were used in the order of screen capture, picture, picture, table, illustration, illustrative function, and use.

Yongdoseo and Guimunwon are described in "Bokgeo(卜居, fixabode)" of "Sanlimkyengje(山林經濟)" written by Manseon Hong. This record is a unique garden conceptual idea applying the principles of Hetu(河圖) and Luoshu(洛書), fanciful gardens which have not been actually constructed. Here, two garden types were concretely described respectively, however the underlying meaning therein cannot be apprehended without exact understanding about Sangsu studies. Therefore, the purpose of this study is to illuminate the meaning contained in Garden illustration and the historical meaning of landscape therein through considering this text. To achieve the purpose of this study, the writer and the compiler who are the background of this writing and the outline of Sangsu studies were investigated. Also, the principles of Saengsu(生數), Seongsu(成數), Yin Yang(陰陽), Four Bodies(四象), Palgwedo(八卦圖), etc. which are in Hetu and Luoshu were considered. The result of this study went through this research process is summarized as follows. First, Hetu Luoshu are conceptual definitions which wholly abstracted the basic propositions of Sangsu philosophy such as the universe change principle, etc., while Yongdoseo and Guimunwon can be said to be operational definitions which apply those as garden composition principle, enabling to experience the meaning contained therein concretely and explain it in a replicable way. This attempt is a unique example, unprecedented in Chinaas well. Second, as a livingspace, garden was selected as a means to concretize operational definitions about the meaning of Hetu Luoshu, and as the property to reproduce the bearings concept, the location and the number, etc. of Hetu Luoshu, Taegukjeong(太極亭), Shipjagak(十字閣), Dondae(墩臺), well, pond as well as various kinds of trees were used. Third, the main motif of Yongdoseo and Guimunwon is the relation between Apriority(先天) and Posterior(後天), and the relation between Constitution(體) and Use(用) of Hetu and Luoshu respectively. That is, Yongdoseo planted evergreen trees such as Shipjangcheong(十長靑) in order to symbolize the universe creation principle which Hetu stands for, i.e. silent, harmonious, orderly and win-win image. In Guimunwon, flowering trees(花木) and fruit trees(果木) were planted freely to express the change of Posterior which Luoshu stands for, thatis, dynamic, disharmonious, disorderly, incompatible(相剋) and changing image. The effects intended to be attained through such planting were, 'freshness and cheerfulness(淸爽)' of Yongdoseo and 'splendidness' of Guimunwon respectively. Sangsu studies based on Hetu and Luoshu is a unique thinking system to the Orient which came from the accumulated wisdom of several scholars from various schools through a long period since ancient times. Therefore, the concept and the theory thereof are profound and huge, and its viewpoints of interpretation are diverse. It is a limit of this study that more in-depth and various consideration was not performed. As a further research project, more empirical study of Orientalism such as Sangsu studies, etc. inherent in Traditional Garden is necessary.

Since the implementation of the Living Modified Organisms (LMOs) Act in 2008, approximately 10 million tons of genetically modified corn, soybean, potato, canola, and other crops have been imported into South Korea. The import approval procedures have been completed for approximately 191 cases that include seven crops. Of these, approximately 90 cases, excluding crossbreeds of approved LMOs, were reviewed via consultation risk evaluation in four areas: human health, crop culture, natural ecology, and marine fishery environment. LMO developers in South Korea, who are major stakeholders in the import of LMO crops produced overseas, have raised concerns regarding procedural inefficiency in consultation reviews and the need of excessive reviews that are unsuitable for food-feed processing purposes. These procedures reflect the perspective of consultation agencies that deviate from the nature of risk assessment and demand specific supplementary data that do not reflect familiarity and substantial equilibrium. Based on frequent instances of unintentional environmental release of LMO crops imported into Korea, the ministries responsible for consultation insist on a review that considers the climate and natural environment of Korea. In addition, the ministries mandate that their reviews reflect the expertise of competent ministries and are based on risk assessment principles and methods in accordance with international guidelines. In this regard, considering that traits introduced into LMO crops involving familiar agricultural crops have been considered safe for more than two decades, we have suggested reasonable alternatives to several risk assessment items for agricultural LMOs. These alternatives can mitigate conflicts of interest among key stakeholders within the scope of the current LMO regulations.

최근 물 사용 및 배분과 관련하여 각종 갈등이 첨예화 되면서 수리권에 대한 체계적인 정리가 필요하게 되었다. 특히, 각종 수리권의 적용 범위나 한계를 논하기 위해서는 근본적으로 하천의 자연유량과 인공유량에 대한 이해가 우선되어야 하는데 이는 수리권의 본질을 이해하는데 기본적인 사항이다. 이를 통해 자연스럽게 '강변수리권'과 '지역수리권', 그리고 또 다른 대표적인 수리권인 '점용수리권'에 대한 비교 검토를 함으로써 수리권에 대한 올바른 인식을 가능하게 하며 이로 인해 물의 합리적이고 효율적 배분에 기여할 수 있다. '강변수리권'은 오로지 강변에 위치한 토지에 필요한 물에 대해서만 적용되는 수리권으로 결과적으로 농업용수에 대한 권리이며 지방자치단체가 아닌 강변 토지 소유자에게 부속되어 있고 하천의 자연유량에만 적용되어 댐 건설로 인해 추가적으로 발생하는 유량에 대해서는 적용하지 않는다. 또한, '강변수리권'은 비록 사용하지 않아도 소멸되지 않으나 한번 소멸되면 회복할 수 없으며 타인에게 양도할 수 없다. 아울러 '강변수리권'끼리는 똑같은 우선권이 있기 때문에 물이 부족한 시기에는 주어진 양을 공유해서 사용하여야 하며 소량이지만 생활용수로 사용코자 하는 경우에는 등록증서가 필요하며 물을 저장해서 다른 시기에 쓰고자 한다면 수리권 허가가 필요하다. '점용수리권'은 "특정 기간동안 특정장소에서 특정한 용도로 특정 수원(水源)으로부터 특정한 양을 취수하는 배타적 권리이다". '점용수리권'은 물의 가용성(availability)을 기초로 하고 있으며 합리적이고 유용한 용도에 사용하는 것을 일반적인 원칙으로 하고 있다. '점용수리권'은 '선점수리권(first in time, first in right)'이라고도 하는데 '강변수리권'과는 다르게 강변에 인접하지 못한 토지소유자가 물을 취수하여 물을 이동시킬 수 있는 권리로 허가없이 증량할 수 없으며 5년간 사용하지 않는 경우에는 소멸된다. '점용수리권'을 얻고자 하는 사람은 장기간 물을 저장하여 사용하고자 하는 '강변수리권자'나 강변에 인접하지 않은 토지에서 지표수나 지하수를 저장하거나 사용하고자 하는 사람들이다. '지역수리권'을 뒷받침하는 사례로 자주 이용되는 미국의 경우에 주(州) 헌법이나 주(州) 수법에 주(州)내의 모든 물은 주(州)의 주민에 속한다고 천명하고 있다. 그러나, 추가적으로 수질관리, 홍수관리, 댐 운영, 재해방지 등 물과 관련한 포괄적인 기능도 주(州)의 책임으로 명시하고 있어 지방정부주(州)가 단지 물의 사용에 대한 권리만 위임받은 것이 아니며 물 관리에 따른 모든 책임까지도 함께 담당하고 있다는 우리나라와 같이 지방자치단체의 물 이용에 대한 권리만 의미하는 '지역수리권'과는 근본적으로 다름을 알 수 있다.

물론 이 글이 콘크리트 분야에 종사하는 사람이 알아야 하는 모든 것을 언급하지는 않는다 ; 본인의 저서 'Properties of Concrest'의 판매에 나쁜 영향을 주고 싶지도 않다. 내가 원하는 것은 콘크리트를 제작할 때 우리 모두가 주의를 기울여야 하는 중요한 몇 가지를 강조하는 것이다. 포트랜드 시멘트만 들어있는 보통의 콘크리트가 사용되는 시대는 이미 사라져가고 있고, 단순한 응용을 제외하고는 곧 사라질 것이다. 대부분의 경우는 가능한 일련의 시멘트계 재료 중에 선택을 해야 한다. 혼화제, 특히 고성능 감수제는 중요한 역할을 한다. 물을 많이 첨가하는 것이 작업성을 높이는 유일한 방법도 아니고 최선의 방법도 아니다. 성능을 기준으로 한 기준설정에 관여하는 사람은 이 모든 것을 명심해야 한다. 그렇지 않으면 시방기준에 명시된 규정과 근원적인 요구사항이 잘못 이해되고, 시험배합을 통해서만 잘못되었다는 것이 분명해지게 된다. 그 단계에서는 예상보다, 비록 틀린 것이지만, 더 많은 비용이 들 것이다. 시방규정은 통상적인 조항 외에 갈수록 내구성에 관심을 더 많이 보인다. 가끔은 내구성이 구조물의 기대수명에 대한 연수로 표현되기도 한다. 이 숫자를 배합재료에 관한 자료로 변환시키는 데는 여러 배합재료 및 배합비가 콘크리트의 성질에 미치는 영향에 관하여 깊이 알고 있어야 한다. 모든 사람이 그러한 구체적인 지식을 가질 필요는 없지만, 각 조직마다 상의할 수 있는 사람은 있어야 한다. 엔지니어가 언급한 규정이 따로 없고, 도면의 주를 참고하거나 구체적인 절이 명시되지 않은 상태에서 국가 시방기준을 통해서 조금씩 내용을 수집해야 하는 경우의 상황은 더 난감하다. 이러한 경우는 배합설계나 재료의 선택을 책임지고 있는 사람이, 환경에 대한 노출조건 및 필요한 배합재료에 관하여 잘 알고 있어야 한다. 일반적으로 말해서 콘크리트의 배합은 필요한 특정용도에 따라서 선택되어야 한다. 이것이 사람들이 고성능 콘크리트라 부르는 것이라고도 할 수 있다. 내 생각으로는 고성능 콘크리트와 보통 콘크리트의 경계는 곧 사라질 것이고, 앞으로 대다수 고객에게 주문 콘크리트 혹은 맞춤 콘크리트를 제공해야 할 것이다. 만약 이러한 접근방식에 더 많은 비용이 든다면, 그것을 보상하는 방법은 콘크리트에 대한 이미지를 높이고, 또한 앞으로 모든 용도에 계속적으로 이용될 수 있도록 하는 것이다. 아니면 구조물을 보수하고, 보수한 것을 또 보수하고, 해체하고 해야 할 것이다. 결국은 재활용 골재를 생산할 수 있다고 웃으면서 말할지 모르지만, 이런 식으로는 불만을 지닌 사용자가 콘크리트를 가능하면 멀리하게 만들 것이다. 콘크리트는 절대 심각한 경쟁에 처하지 않을 것이라는 가정은 무모하다. 내가 배합비에 대해서 강조해 왔지만, 이것으로 최종적으로 좋은 콘크리트가 된다는 보장은 없다. 비빔에서는 일반적으로 큰 문제는 없지만 골재에 함유된 수분을 더 잘 제어해야하고 주의를 게을리하지 말아야 한다. 비빔시간은 모든 재료가 잘 섞이기에 충분해야 하는데, 마이크로 실리카가 포함되어 있을 경우에는 더욱 그렇다. 단위시간당 믹서의 작업량을 높이기 위해서 충분히 비비지 않아서는 안된다. 그리고 마지막으로, 콘크리트가 타설되고 다져진 후, 적절하게 양생이 되어야 한다. 마이크로 실리카가 배합에 사용되었을 경우에는 특히 그러하지만, 이것은 모든 콘크리트에서 양생을 잘하는 것이 피복부에서 유해물질이 유입되는 것을 최소화하고 철근을 완전히 보호하는데 있어서 절대적이다. 내가 지금까지 말한 것은 콘크리트에 관한 충분한 지식과 이해를 필요로 한다. 이것은 당연하고 또한 적절한 것이라고 생각한다. 왜냐하면 더 이상 콘크리트를 수준낮은 싸구려 재료로 간주해서는 안되기 때문이다.

There has been a conflict over the use of private forest in Mt. Jiri National Park among the stakeholders. Therefore, the purpose of this study is to define each stakeholders' recognition difference about value and conflict of Mt. Jiri National Park and find the possibility of creating agreement point for solving conflict. For the purpose, the study performs factor analysis on the value of national park and conflict factor and abbreviates them to 4 factors respectively. The study classifies and compares the recognition difference among the stakeholders with t-test and Duncan multiple comparison. The result of this study is that village residents, Korea Forest Service and local autonomy share the same recognition about the value of national park but National Park has different recognition. Regarding the conflict, National Park, Korea Forest Service and local autonomy share the same recognition but village residents have different recognition. Regarding the organization of conference as a direction to solve conflict and its reason, all of the stakeholders share the same recognition. It is necessary to adopt clear standard for the use of forest and apply the different execution of regulation to each area.
