오늘날 재순환에 대한 사회적 관심이 고조되고 있는 바, 순환되는 물품들의 수량과 그 시기를 추정하는 것이 관리측면에서 강조되고 있다. 이 논문에서는 Weibull Distribution을 이용하여 개발된 Turnaround Time Distribution의 빈병의 회수 특성을 보여 주고 있다. Turnaround Time Distribution을 사용하여 추정 Model이 만들어졌으며 이 추정 Model은 회수되는 빈병의 수량을 추정해 주고 있다. 이 Model은 기존 방법보다 15%의 예상 오차를 줄여주었고, 재고관리 측면에서는 추정 Model을 확장하여 두 가지의 관리방법이 고려되었다.

Purpose: To compare long-term disease-free survival (DFS) between patients receiving tegafur/gimeracil/oteracil (S-1) or capecitabine plus oxaliplatin (CAPOX) adjuvant chemotherapy (AC) for gastric cancer (GC). Materials and Methods: This retrospective multicenter observational study enrolled 983 patients who underwent curative gastrectomy with consecutive AC with S-1 or CAPOX for stage II or III GC at 27 hospitals in Korea between February 2012 and December 2013. We conducted propensity score matching to reduce selection bias. Long-term oncologic outcomes, including DFS rate over 5 years (over-5yr DFS), were analyzed postoperatively. Results: The median and longest follow-up period were 59.0 and 87.6 months, respectively. DFS rate did not differ between patients who received S-1 and CAPOX for pathologic stage II (P=0.677) and stage III (P=0.899) GC. Moreover, hazard ratio (HR) for recurrence did not differ significantly between S-1 and CAPOX (reference) in stage II (HR, 1.846; 95% confidence interval [CI], 0.693–4.919; P=0.220) and stage III (HR, 0.942; 95% CI, 0.664–1.337; P=0.738) GC. After adjustment for significance in multivariate analysis, pT (4 vs. 1) (HR, 11.667; 95% CI, 1.595–85.351; P=0.016), pN stage (0 vs. 3) (HR, 2.788; 95% CI, 1.502–5.174; P=0.001), and completion of planned chemotherapy (HR, 2.213; 95% CI, 1.618–3.028; P<0.001) were determined as independent prognostic factors for DFS. Conclusions: S-1 and CAPOX AC regimens did not show significant difference in over-5yr DFS after curative gastrectomy in patients with stage II or III GC. The pT, pN stage, and completion of planned chemotherapy were prognostic factors for GC recurrence.

이창민 사단법인 한국조형디자인협회 2024 조형디자인연구 Vol.27 No.1

텍스타일 산업의 최신 동향으로 빼놓을 수 없는 것으로 ‘지속가능성’을 꼽을 수 있다. 산업화에 따라 환경보전을 필수 해결 과제로 인식하는 경향이 나타났으며, 다수의 산업에서 이를 수용하는 변화의 움직임이 드러나고 있다. 선진국을 필두로 생태환경의 중요성을 생각하는 가치관이 크게 향상되었고 곧 국가의 정책, 기업 및 브랜드의 마케팅 전략에도 중대한 영향을 끼쳤다. 이와 같은 사회적 움직임 속에서 텍스타일 분야 역시 지속가능한 발전을 위한 변화에 주목하고 있다. 본 연구에서는 실크스크린과 디지털 텍스타일 프린팅(이하 DTP)에 대해 살펴보고, 지속가능한 발전 패러다임에 따른 변화 양상과 해당 기술들에서 관찰되는 최신기술동향을 분석하였다. 상기의 기술들은 패션 및 인테리어 분야에서 디자인 트렌드의 창출과 직결되는 필수적인 기술로, 산업 전반에서 활용되는 비중이 크다. 그에 따라 실크스크린과 DTP는 지속가능한 발전이라는 측면에서 공정개선·기술개발·신소재 도입 등 산업의 구조와 체질을 보완하는 방식으로 발전되고 있다. 실크스크린에서는 환경 친화적인 재료의 도입과 감광공정을 생략할 수 있는 새로운 방식의 기계 개발을 통해 모습이 나타났으며, DTP 기술에서는 고도화 된 기계 개발을 통한 기능성 향상 및 생산 속도 증대를 이끌었다. 또한 천연 잉크의 개발을 통한 상용화 단계에 도입하는 등 변화된 최신기술동향을 살펴봄으로써 현재 실크스크린과 DTP 산업의 현주소를 파악하였다. 이를 토대로 더 나은 지속가능한 발전 방안을 모색하고 수준 높은 차원의 텍스타일 산업 행보를 기대해 볼 수 있다. ‘Sustainability’ stands out as a critical trend in the textile industry, especially when viewed from a broader perspective. The onset of industrialization has led to the recognition of environmental conservation as a vital challenge, with a noticeable movement towards embracing these changes evident across various sectors. Led by developed countries, there has been a significant increase in the value placed on ecological and environmental concerns, which has had a profound impact on the policies of nations, as well as the marketing strategies of companies and brands. In the midst of these societal shifts, the textile sector is also focusing on changes aimed at sustainable development. This study examines silkscreen and digital textile printing (referred to as DTP), analyzing the changes prompted by the sustainable development paradigm and the leading technological trends in the textile industry. These technologies play a significant role in the industry and are particularly recognized as essential for driving design trends in fashion and interior design. As such, silkscreen and DTP are undergoing developments aimed at improving processes, advancing technology, and incorporating new materials. In silkscreen, new methods of machine development have emerged, allowing the introduction of environmentally friendly materials and eliminating the photomechanical process. In DTP technology, the development of advanced machinery has led to enhanced functionality and increased production speed. Furthermore, examining the latest technological trends, such as the commercialization of natural inks, provides insights into the current status of the silk screen and DTP industries. Based on this assessment, the study seeks to identify more effective strategies for sustainable development and anticipates progress towards a more advanced textile industry.

債權者代位訴訟에서 訴却下 判決이 있었던 경우 그 判決의 旣判力이 債務者에게 미치는지 여부

이창민 민사판례연구회 2015 民事判例硏究 Vol.- No.37

In its judgment that is the subject of this paper(the "Subject Judgment"), the Supreme Court held that "where the dismissal of a creditor's subrogation suit was confirmed because the creditor's underlying claim against the debtor could not be acknowledged, the doctrine of res judicata does not apply to a suit by the creditor against the debtor for performance of such underlying claim where there is a dismissal of action due to lack of standing as a "special litigant" (i.e., a person who has the legal right to bring suit on behalf of another person for their claim), as in the Subject Judgment where there was a deficiency with respect to the creditor's underlying claim which is a necessary element for the creditor to have standing as a special litigant in a subrogation action, such dismissal cannot be viewed as a "judgment against the special litigant", and thus, the doctrine of res judicata cannot be applied to the original holder of the right. Therefore The Subject judgment is valid, not inconsistent with the precedents that view that the creditor in a subrogation suit is a special litigant for the debtor's claim against a third-party and that the doctrine of res judicata applies to the debtor that has knowledge of such subrogation suit. However, the Subject Judgment is unclear as to whether the doctrine of res judicata would apply to the debtor where there is a dismissal of a creditor's subrogation suit based on a deficiency with respect to the debtor's original claim against the third-party. Based on the language of the Subject Judgment, it appears likely to that the Supreme Court's position would be understood as saying that wherever there is a dismissal decision, including in such case, the doctrine of res judicata would not apply to the debtor. If such is the Supreme Court's position, the court should reconsider it in light of preventing conflicting precedents, as it would be consistent with the precedents' view(i.e., that the creditor in a creditor's subrogation suit is a special litigant and that the doctrine of res judicata applies to a debtor that has knowledge of such subrogation suit), to say that a dismissal based on a deficiency with respect to the debtor's original claim is a judgement against the special litigant (as there is no lack of standing in this case) and that would apply to the holder of the original claim, debtor. 대상판결은 “채권자대위소송에서 피보전채권이 인정되지 않는다는 이유로 소각하 판결을 받아 확정된 경우 그 판결의 기판력이 채권자가 채무자를 상대로 피보전채권의 이행을 구하는 소송에 미치는 것은 아니다.”라고 판시하였다. 소송담당자로서의 자격과 관련된 당사자적격의 흠결로 소각하 판결이 있었던 경우에는 그 판결은 ‘소송담당자’에 대한 확정판결이라고 볼 수 없어 권리귀속주체에게 기판력이 미칠 수 없다. 따라서 채권자를 소송담당자로 보고 채권자대위소송의 기판력이 채권자대위소송이 제기된 사실을 안 채무자에게는 미친다는 판례의 입장에 의하더라도, 대상판결의 결론은 타당하다. 다만, 대상판결은 피대위채권에 관계된 소송요건이 흠결되어 채권자대위소송에서 소각하 판결이 있었던 경우에 그 판결의 기판력이 채무자에게 미치는지 여부에 대한 입장은 명확하게 밝히지 아니하고 있는데, 대상판결 이유의 문언을 보아서는 피대위채권에 관계된 소송요건의 흠결을 이유로 한 것을 포함하는 모든 소각하 판결의 기판력이 채무자에게 미치지 않는다고 받아들여질 가능성이 더 높아 보인다. 만약 대법원의 입장이 그와 같다면, 대법원은 판례의 모순․저촉 방지라는 측면에서 향후 다시 한 번 검토해 볼 필요가 있다. 채권자대위소송을 제기하는 채권자를 소송담당자로 보고, 채무자가 채권자대위소송이 제기된 사실을 안 경우에 채권자대위소송의 기판력이 채무자에게 미친다는 판례에 의할 때, 피대위채권에 관계된 소송요건이 흠결되어 소각하 판결이 있었던 경우에는 ‘소송담당자’에 대한 확정판결이라 할 수 있으므로, 소송요건의 흠결에 관하여 발생한 소각하판결의 기판력이 권리귀속주체인 채무자에게 미친다고 봄이 타당하기 때문이다.

도시 물 문제 저감을 위한 회복탄력적 사회기반시설 구축: 1. 도시 홍수 문제 구조적 대안의 내구성 평가

이창민,정지현,안진성,김재영,최용주,Lee, Changmin,Jung, Jihyeun,An, Jinsung,Kim, Jae Young,Choi, Yongju 응용생태공학회 2016 Ecology and resilient infrastructure Vol.3 No.2

도시 내 인구집중과 기후변화로 인해 다양한 형태의 도시 물 문제가 발생한다. 이에 대한 피해 예방과 사회적 손실 최소화를 위해 회복탄력적인 대안 수립이 필요하다. 본 연구는 도시 물 문제 저감을 위한 회복탄력적 사회기반시설 구축 전략 수립에 관한 기초연구로서, 대표적인 도시 물 문제 중 하나인 도시홍수를 사례로 하여 구조적 대안의 내구성을 평가하였다. 내구성 평가를 위한 지표로 내구성 지수 (robustness index, RI) 및 비용지수 (cost index, CI)를 결합한 내구성-비용지수 (robustness cost index, RCI)를 제안하고, 이를 강남역 상습침수구역에 적용하여 기존 기반시설과 구조적 대안 (하수관거 확충, 저류조 설치, 옥상녹화)을 평가하였다. 그 결과, 2~20년 빈도의 강우강도범위에서 저류조와 옥상녹화설치가 상대적으로 높은 RCI 값을 나타내었고 두 대안 중 RCI가 보다 높은 대안은 강우강도에 따라 달라지는 경향을 보였다. 30년 빈도 강우강도에 대하여는 저류조와 옥상녹화를 병용 설치하는 대안이 가장 높은 RCI 값을 나타내어 가장 회복탄력적인 대안으로 확인되었다. 최종적으로 재해의 계획규모에 따른 현행 사회기반시설의 내구성 평가 및 최적의 구조적 대안 선택 절차를 수립하여, 도시홍수 문제에 대한 회복탄력적 사회기반시설 구축 전략을 제시하였다. Current cities encounter various types of water problems due to rapid urbanization and climate change. The increasing significance of urban water problems calls for the establishment of resilient alternatives to prevent and minimize social loss that results from these phenomena. As a background research for establishing resilient infrastructures for the mitigation of urban water problems, we evaluated the robustness of structural alternatives for urban flood as a representative case. Combining the robustness index (RI) and the cost index (CI), we suggested the robustness-cost index (RCI) as an indicator of the robustness of structural alternatives, and applied the index to assess the existing infrastructures and structural alternatives (i.e., sewer network expansion, additional storage tank construction, and green roof construction) at a site prone to floods located around Gangnam-station, Seoul, Korea. At a rainfall intensity frequency range of 2 to 20 years, the usage of a storage tank and a green roof showed relatively high RCI value, with a variation of an alternative showing greater RCI between the two depending on the size of design rainfall. For a rainfall intensity frequency of 30 years, installing a storage tank with some green roofing was the most resilient alternative based on the RCI value. We proposed strategies for establishing resilient infrastructures for the mitigation of urban floods by evaluating the robustness of existing infrastructures and selecting optimal structural alternatives with the consideration of scales of design disaster.

코퍼스 분석을 통한 ‘得’자보어문의 유형 및 빈도 연구 - 출현빈도에 따른 학습방안

이창민 동북아시아문화학회 2020 동북아 문화연구 Vol.1 No.65

This study primarily categorized the sentences containing the complement ‘de’ characters from Corpus, which shows the actual language use of Chinese native speakers, and analyzed its frequency of appearance and distribution by introducing Corpus Linguistics in order to analyze Complement Structure with ‘de’; which is used to emphasis the degree of the verbs. Also the characteristics of the structured type of Complement Structure with ‘de’ were examined by focusing on the extracted sentences. Firstly, relating to the name and classification of Complement Structure with ‘de’, the boundaries are ambiguous with meaning criteria like ‘degree’, ‘state’, and ‘result’, it is reasonably judged to classify it on the principle that form and meaning are combined. Secondly, Complement Structure with ‘de’ is classified into seven types depending on the structure of the complement: pattern(1) NP+V/A+‘de’+Adv, (2) …+de’+AP, (3) …+‘de’+VP, (4) …+‘de’+像…一樣, (5) …+‘de’+NP2+VP, (6) …+‘de’+NP2, and (7) …+‘de’+Idiom, etc. The order on the basis of the frequency of appearance is pattern(2) → pattern(3) → pattern(5) → pattern(1) → pattern(4) → pattern(6) → pattern(7). I think that statistical analysis through these data can also be used to establish a basis for determining the basic sentence patterns in teaching and education, that is, exemplary sentences. Thirdly, the phased teaching plan of Complement Structure with ‘de’ was suggested as follows focusing on four types of sentence patterns (1), (2), (3), and (5) with high ratio of appearance. The above discussion is likely to be exploratory to highlight the necessity of a step-by-step teaching plan. I hope this intention becomes widespread so that the existing learning methods for Complement Structure with ‘de’ can be more systematic the appropriate teaching methods to be posed.

GaN is most commonly used to make LED elements. But, due to differences of the thermal expansion coefficient and lattice mismatch with sapphire, dislocations have occurred at about $109{\sim}1010/cm^2$. Generally, a low temperature GaN buffer layer is used between the GaN layer and the sapphire substrate in order to reduce the dislocation density and improve the characteristics of the thin film, and thus to increase the efficiency of the LED. Further, patterned sapphire substrate (PSS) are applied to improve the light extraction efficiency. In this experiment, using an AlN buffer layer on PSS in place of the GaN buffer layer that is used mainly to improve the properties of the GaN film, light extraction efficiency and overall properties of the thin film are improved at the same time. The AlN buffer layer was deposited by using a sputter and the AlN buffer layer thickness was determined to be 25 nm through XRD analysis after growing the GaN film at $1070^{\circ}C$ on the AlN buffer CPSS (C-plane Patterned Sapphire Substrate, AlN buffer 25 nm, 100 nm, 200 nm, 300 nm). The GaN film layer formed by applying a 2 step epitaxial lateral overgrowth (ELOG) process, and by changing temperatures ($1020{\sim}1070^{\circ}C$) and pressures (85~300 Torr). To confirm the surface morphology, we used SEM, AFM, and optical microscopy. To analyze the properties (dislocation density and crystallinity) of a thin film, we used HR-XRD and Cathodoluminescence.

다탄성 Insole의 Workload 감소 효과에 관한 연구

이창민,이경득,오연주,김진훈,Lee, Chang-Min,Lee, Kyun-Deuk,Oh, Yeon-Ju,Kim, Jin-Hoon 대한인간공학회 2007 大韓人間工學會誌 Vol.26 No.2

The Work-Related Musculoskeletal Disorders (WMSDs) can be occurred by various factors such as repetition, forceful exertions and awkward postures. Especially, occurrences of the WMSDs on the waist and lower limb are reported in workplaces, demanded standing postures for a long time, in service and manufacturing industry. The static and standing postures without movement for a long time increase work loads to the lower limb and the waist. Accordingly, anti-fatigue mat or anti-fatigue insole is used as a preventing device of the WMSDs. However anti-fatigue mats are limited in space and movement. In this study, multi-elastic insoles are designed and shown the effects of the workload reduction for a long time under the standing work. The foot pressures and EMG (Electromyography) are measured at 0 hour and after 2 hours by 6 health students in their twenties. The 6 prototype insoles are designed with three elastic (Low, Medium and High). These insoles are compared with no insole (insole type 7) as control group. The EMG measurement was conducted to waist (erector spinae muscle), thigh (vastus lateralis muscle) and calf (gastrocnemius muscle). The foot pressure is analyzed by mean pressure value and the EMG analysis is investigated through MF (Median Frequency), MPF (Mean Power Frequency) and ZCR (Zero Crossing Rate). The results of the foot pressure show that the multi-elastic insoles had smaller foot pressure value than that of no-insole. Moreover, Insole 2 and Insole 3 have the smallest increasing rate in foot pressure. The EMG results show that the multi-elastic insoles had smaller EMG shift value than that of no-insole in 2 hour, and then shift value shows the smallest value in Insole 2. Therefore, this study presents that the multi-elastic insoles have reducing effects of the work load for a long time standing work in both side of foot pressure and EMG.
