This paper aims to investigate best practices of collaborative supply chain management. To meet this objective, this paper conducts a case study on iCOOP consumer co-operative and draws causal loop diagrams. It will name three key strategic policies related to customer-supplier partnerships and demonstrate how they enhance iCOOP’s supply chain performance. The three strategic policies are 1) win-win pricing policy, 2) membership fee, and 3) customer cash advance payment. Additionally, the paper will show how these three policies create positive feedback loops which enhance the iCOOP’s supply chain performance as a whole. Particularly, the three policies foster a more amicable relationship among supply chain partners which elevates supply chain performance as a whole over time. This case could serve as a model for companies who are looking to build more sustainable supply chain partnerships that are powered by trust.

A Study on Inclusive Growth on APEC Economies: Focusing on Small and Medium-sized Enterprises (SMEs)

김다솜(Dasom Kim),구선미(Sunmi Koo),홍혜기(Haegi Hong) 한국APEC학회 2020 Journal of APEC Studies Vol.12 No.2

The latest development model, known as “inclusive growth,” is a practical solution to current issues: wealth gap, income inequality, severe environmental pollution, and waste of resources. APEC promotes inclusive growth with different initiatives and frameworks to strike a balance between economic and sustainable development. This paper explores and examines SMEs as potential sources for APEC member economies’ inclusive growth as SMEs contribute about 20 percent to 50 percent of GDP in most APEC economies. However, SMEs only account for 35 percent or less of direct exports. This shows that there is some room for improvement in SME’s contribution to international trade. In this regard, SMEs have been APEC’s focus for inclusive growth with advancing youth and women’s engagement to economic activity. Youth has been a significant part of APEC’s agenda since 1998. Women have been listed as an important agenda in APEC since 1999 and listed as one of four priority areas of APEC in 2019. Youth and women are often referred to as economically vulnerable groups. However, if they are empowered with adequate policies and practices, they can generate individual income and develop successful small and mediumsized businesses. In this regard, we examine definitions and current status of SMEs in APEC member economies, explore good policies and practices regarding the subject and provide recommendations for future policies and practices for these cross-cutting issues in APEC.

김다솜(Dasom Kim),이승복(Seungbok Lee),안길환(Gilhwan Ahn) 한국추진공학회 2018 한국추진공학회 학술대회논문집 Vol.2018 No.5

최근, 착화장치 성능이 정밀해짐에 따라 압력 계측시스템 또한 신뢰성이 요구되고 있다. 일반적으로 착화장치 성능시험은 밀폐용기 시험(CBT) 방식을 사용하고 있다. 그러나 전원인가장치, 압력 센서와 저역통과필터의 변수는 압력 계측 값의 신뢰성을 저하시키는 주요한 요인 중 하나이다. 본 논문에서는 압력 계측시스템이 착화장치 신뢰성에 미치는 영향을 분석하였다. 또한 착화장치 계측시스템의 표준안을 제시하였다. Recently, as the accuracy of initiator performance has been improved, pressure measurement system demands reliability. Performance test of initiator is generally applied to CBT(Closed Bomb Test). However, power supply, variable of pressure sensor and LPF(Low Pass Filter) is regarded as one of the primarily causes for measurement value of pressure degradation. In this paper, the reliability degradation mechanism of initiator performance induced by variable of pressure measurement system. Also, a standard for the measurement system is presented.

현대의 윤리적 문제와 그 해결을 위한 철학적 근거 : 응용윤리학의 주제와 문제를 중심으로

김다솜(Kim, Dasom) 한국인간과자연학회 2021 인간과자연 Vol.2 No.1

윤리적인 문제는 그 성격상 이론과 실천이 분리될 수 없는 성질을 갖는다. 다만 어떤 문제에 좀 더 많은 관심을 가졌는지에 따라 서로 차이가 닐 따름이다. 그래서 전통적인 윤리학은 주로 보다 덩어리가 큰 문제들에 관심을 가진 반면, 현대 윤리학은 보다 작은 문제들에 더 많은 관심을 가져야 할 사회적 요구와 필요성에 직면한 것이라고 할 수 있다. 특히, 현대에 들어 우리의 윤리적 판단을 혼란스럽게 만드는 것은 빈부 격차, 경제적 갈등, 정치적 불안, 실업, 폭력과 범죄, 민족 간의 갈등과 종교 분쟁, 환경오염, 가상현실, 그리고 유전자 조작된 음식이나 동식물, 생명 복제 등 수많은 문제들이 개입되어 있기 때문이다. 이에 본 논의에서는 이러한 복합적인 문제들을 해결하기 위한 윤리적 접근으로 응용윤리학의 성격과 특징에 대해 살펴보고, 현대의 복합적인 문제들을 해결하기 위한 윤리학적 답변에 대해 살펴보는데 있다. Ethical problems have the inseparable nature of theory and practice. However, there are differences depending on the type of problem you are more interested in. Therefore, while traditional ethics is mainly concerned with larger problems, modern ethics faces social needs and needs to pay more attention to smaller problems. In particular, Korea’s ethical judgments are confusing because of the gap between rich and poor, economic conflicts, political unrest, unemployment, violence and crime, ethnic conflicts and religious disputes, environmental pollution, virtual reality, and genetically modified food, plants and animals. Therefore, this discussion examines the characteristics and characteristics of applied ethics as an ethical approach to solving such complex problems, and examines the ethical answers to solve modern complex problems.

Purpose: This study was intended to integrate the evidence of home care service intervention for mothers and children in vulnerable groups through an integrative literature review. Methods: We searched the MEDLINE (PubMED), EMBASE, Cochrane Central Register of Controlled Trials, CINAHL, DBpia databases. The quality of the articles was assessed by one doctoral researcher and verified by one professor of community health nursing who had participated in the systematic review of literature. A framework was developed to identify the intervention patterns in the selected papers and categorize various elements. The extracted intervention elements were grouped into potential themes, which were verified by assessors on whether they clearly reflected the interventions in the papers. Results: Among 878 searched papers, we selected 16 papers after excluding literature that does not satisfy the selection criteria and quality evaluation. The intervention elements of 16 selected papers were categorized into six themes. The extracted intervention elements were divided into the themes of Patient-specific/Situation-specific care planning and intervention, Emphasis on self care competency, Intense home visit by developmental milestone, Reinforcing and modeling motherchild attachment, Communication and interaction across the intervention, Linkage with community resource and multidisciplinary approach. Conclusion: As a result of the analysis of proper interventions of home care services for mothers and children in vulnerable groups, it was found that it is necessary to consider indispensable intervention elements that can standardize the quality of home care services, and conduct studies on developing intervention programs based on the elements.

Due to the recent increase in lighting energy consumption in buildings, there are a growing number of studies seeking solutions this problem. The effectiveness of light-shelves as natural lighting systems to solve this problem has been recognized, and various studies regarding such systems are being carried out currently. However, the lighting efficiency of light-shelves decreases if illumination intensity is low-such as at night time, and it also obstructs the views of building occupants. Therefore, the purpose of this study is to examine a movable drawer type light-shelf which allows for the width of the reflector to be adjusted and verify its performance through a simulated test-bed. The following conclusions were reached. 1) The purpose of this study is to solve the problem previously associated with the light-shelf system- of obstructed views-by responding to external environments and minimizing the width of the light-shelf at night time when the efficiency of the light-shelf declines. 2) The proper variables of the movable drawer type light-shelf which enables the width adjustment of the reflector were ascertained in this study according to four solar terms : a width of 0.6 m at an angle of 20°, a width of 0.4m with an angle of 20°, and a width of 0.1 m with an angle of 20° were determined for the summer solstice, fall/spring equinoxes, and winter solstice respectively; revealing that width adjustment of the light-shelf is a significant factor. 3) The movable drawer type light-shelf which enables\width adjustment of the reflector suggested in this study can reduce the lighting energy consumption by 18.7% and 14.3% in comparison to previous light-shelves with a fixed width of 0.3 m and 0.6m, indicating that it is effective for saving energy.

번역가의 가면을 쓴 작가와 독자의 유희

김다솜(Dasom Kim),정보라(Bora Chung) 한국노어노문학회 2018 노어노문학 Vol.30 No.4

안드레이 비토프의 『대칭의 선생』수록작 “트리스트람-클럽의 유고 기록”은 작가(번역가)와 독자의 관계, 그리고 작가의 문학적 행위의 의미에 관한 그의 관점을 드러내는 메타소설이다.『대칭의 선생』에서 비토프는 작가(비토프 자신)를 번역가의 위치에 놓는다. 이때, 작가(번역가)는 선재하는 이야기를 읽고 그것을 번역해 독자 앞에 내놓음으로써 ‘작가’라는 이름을 얻는다. 즉, 작가는 작가이기 이전에 필연적으로 독자로 존재한다. 『대칭의 선생』작품 내부에서 『대칭의 선생』에 수록된 작품의 저자로 언급되는 A. 타이어드 보핀과 우르비노 바노스키, 그리고 비토프를 둘러싼 『대칭의 선생』의 저자에 대한 모순된 진술, “트리스트람-클럽의 유고 기록”에서의 작가와 화자의 관계, 실존하는 인명 및 작품명에 대한 재맥락화는 독자들이 끊임없이 텍스트와 상호작용하며 빈틈을 채우도록 만든다. 이 과정에서 독자는 즐거움을 얻을 뿐 아니라, 기존의 텍스트로부터 자신의 이설을 다시 발생시켜 작가가 될 수 있는 가능성 또한 지니게 된다. 따라서,『대칭의 선생』 및 “트리스트람-클럽의 유고 기록”에 드러난 비토프의 창작관은 작가(번역가)와 독자의 경계가 매우 불분명하며, 모방으로서의 창작이 아닌 변형으로서의 창작이 독자에게 ‘유희’를 제공한다는 것으로 이해된다. Andrei Bitov’s The Teacher of Symmetry is a metafiction which presents Bitov’s viewpoint on the relationship between the writer (translator) and the reader and on the meaning of the writer’s literary acts. “The Inevitability of the Unwritten,” a short story in The Teacher of Symmetry, most succinctly shows the characteristics of metafiction. In The Teacher of Symmetry, Bitov presents himself as the translator instead of the author because, as he explains, he first read the story and became an author by presenting his own interpretation to his readers. Bitov claiming to be the translator may confuse the reader. Also, the reader must endlessly doubt the clues given in the text as the author’s various statements on A. Taird-Boffin, Urbino Vanoski and Bitov himelf self-contradict. Therefore the reader, as she reads, must fill the gap on her own, gather the clues in the text and form her own understanding of the text. The reader may enjoy herself in the process and also may have the possibility of becoming an author herself, creating her own variation from her understanding of the text. Therefore, according to Bitov’s view on literary creation, the line between the author(or translator) and the reader is rather fluid. And it is creation as variation and not creation as imitation that provides the reader with the joy of literary game with the author.

텍스트 분석을 통한 이종 매체 카테고리 다중 매핑 방법론

김다솜(Dasom Kim),김남규(Namgyu Kim) 한국지능정보시스템학회 2016 지능정보연구 Vol.22 No.4

최근 다양한 소셜 네트워크 서비스의 증가로 인해 사용자들은 각자의 목적 및 취향에 따라 여러 매체를 동시에 이용하는 경향을 보이고 있다. 또한 특정 주제에 대한 정보를 수집할 때에도 소셜 네트워크 서비스, 인터넷 뉴스, 블로그 등 여러 매체를 동시에 활용하는 것이 일반적이다. 하지만 다양한 매체를 통해 유통되는 문서들은 서로 유사한 주제, 심지어는 동일한 내용을 다루더라도 각 매체 별 정책 및 기준에 따라 각기 다른 카테고리로 관리되고 있으며, 이는 이종 매체를 아우르는 범위에서 특정 카테고리에 대한 탐색을 수행하고자 하는 시도에 걸림돌로 작용하고 있다. 이러한 제약을 극복하기 위해, 본 연구에서는 기존 매체 고유의 카테고리 체계는 그대로 유지하면서 이종 매체 간 카테고리 매핑을 수행하는 방법을 제시한다. 즉, 개별 문서를 다양한 매체의 관점에서 재분류하고 이러한 결과를 문서에 2차원 레이블로 저장함으로써, 이종 매체에 속한 다양한 문서들을 마치 한 매체에 속한 것과 같이 동일한 카테고리 기준으로 탐색할 수 있는 논리적 장치를 제안한다. 본 논문에서는 국내 인터넷 뉴스 포털 사이트 두 곳의 뉴스 기사 6,000건에 대해 제안 방법론을 적용한 실험을 통해 각 기사에 매체와 카테고리 정보로 구성된 2차원 레이블을 부여하였으며, 매체 간, 지도 학습과 준지도 학습 간, 동질 학습 데이터와 이질학습 데이터 간의 정확도 비교 실험을 수행하였다. 특히 매우 흥미롭게도, 일부 카테고리에서 이질 학습 데이터를 사용한 준지도 학습의 분류 정확도가 지도 학습 및 동질 학습 데이터를 사용한 준지도 학습의 분류 정확도보다 높게 나타나는 현상을 발견하였다. In recent years, the proliferation of diverse social networking services has led users to use many mediums simultaneously depending on their individual purpose and taste. Besides, while collecting information about particular themes, they usually employ various mediums such as social networking services, Internet news, and blogs. However, in terms of management, each document circulated through diverse mediums is placed in different categories on the basis of each source’s policy and standards, hindering any attempt to conduct research on a specific category across different kinds of sources. For example, documents containing content on “Application for a foreign travel” can be classified into “Information Technology,” “Travel,” or “Life and Culture” according to the peculiar standard of each source. Likewise, with different viewpoints of definition and levels of specification for each source, similar categories can be named and structured differently in accordance with each source. To overcome these limitations, this study proposes a plan for conducting category mapping between different sources with various mediums while maintaining the existing category system of the medium as it is. Specifically, by re-classifying individual documents from the viewpoint of diverse sources and storing the result of such a classification as extra attributes, this study proposes a logical layer by which users can search for a specific document from multiple heterogeneous sources with different category names as if they belong to the same source. Besides, by collecting 6,000 articles of news from two Internet news portals, experiments were conducted to compare accuracy among sources, supervised learning and semi-supervised learning, and homogeneous and heterogeneous learning data. It is particularly interesting that in some categories, classifying accuracy of semi-supervised learning using heterogeneous learning data proved to be higher than that of supervised learning and semi-supervised learning, which used homogeneous learning data. This study has the following significances. First, it proposes a logical plan for establishing a system to integrate and manage all the heterogeneous mediums in different classifying systems while maintaining the existing physical classifying system as it is. This study’s results particularly exhibit very different classifying accuracies in accordance with the heterogeneity of learning data; this is expected to spur further studies for enhancing the performance of the proposed methodology through the analysis of characteristics by category. In addition, with an increasing demand for search, collection, and analysis of documents from diverse mediums, the scope of the Internet search is not restricted to one medium. However, since each medium has a different categorical structure and name, it is actually very difficult to search for a specific category insofar as encompassing heterogeneous mediums. The proposed methodology is also significant for presenting a plan that enquires into all the documents regarding the standards of the relevant sites’ categorical classification when the users select the desired site, while maintaining the existing site’s characteristics and structure as it is. This study’s proposed methodology needs to be further complemented in the following aspects. First, though only an indirect comparison and evaluation was made on the performance of this proposed methodology, future studies would need to conduct more direct tests on its accuracy. That is, after re-classifying documents of the object source on the basis of the categorical system of the existing source, the extent to which the classification was accurate needs to be verified through evaluation by actual users. In addition, the accuracy in classification needs to be increased by making the methodology more sophisticated. Furthermore, an understanding is required that the characteristics of some categories that showed a
