강윤구,오택근,이재한,이준영 한국토양비료학회 2023 한국토양비료학회지 Vol.56 No.3

Digital soil mapping (DSM) is a statistical technique that utilizes soil characteristics and environmental factors to create spatial distribution maps representing soil properties. The SCORPAN model, consisting of soil (S), climate (C), organisms (O), relief (R), parent materials (P), age (A) and space (N), describes the environmental factors used in DSM techniques. The objectives of this study were to assess the spatial distribution map of soil carbon stocks in Chungcheong province and predict soil carbon stocks within the 0 - 30 cm depth using DSM technique. The minimum and maximum predicted carbon stocks were 25.11 ton C ha-1 and 183.55 ton C ha-1, respectively, with a mean of 46.92 ± 13.66 ton C ha-1. The spatial distribution map of soil carbon stocks revealed higher carbon stock in Chungcheongbuk-do, particularly in Danyang-gun, while lower carbon stocks were observed in the coastal areas of Chungcheongnam-do. The estimated economic value of soil carbon stocks in Chungcheong province was 406.3 billion won, based on the average soil carbon stock, agricultural land area and carbon offset trading price. The validation outcomes of the DSM are summarized as follows: the model achieved a coefficient of determination (R2) of 0.15, indicating the 15% confidence levels to the validation data. The mean absolute error (MAE) was 20.78, and the root mean square error (RMSE) was 29.51, respectively. The scatter plot between observed and predicted soil carbon stocks revealed that the predicted values were lower than the observed values, indicating a need for improvement in the model’s predictive performance. Therefore, the estimated soil carbon stocks and its spatial distribution map in this study can serve as fundamental information for assessing the potential carbon sequestration capacity of agricultural soils and contributing to climate change mitigation and carbon neutrality efforts.

Clinical Practice Guideline for Accurate Diagnosis and Effective Treatment of Gastrointestinal Stromal Tumor in Korea

강윤구,김경미,손태성,최동일,강혜진,류민희,김우호,양한광 대한의학회 2010 Journal of Korean medical science Vol.25 No.11

Despite the rarity in incidence and prevalence, gastrointestinal stromal tumor (GIST) has emerged as a distinct pathogenetic entity. And the clinical management of GIST has been evolving very rapidly due to the recent recognition of its oncogenic signal transduction pathway and the introduction of new molecular-targeted therapy. Successful management of GIST requires a multidisciplinary approach firmly based on accurate histopathologic diagnosis. However, there was no standardized guideline for the management of Korean GIST patients. In 2007, the Korean GIST study group (KGSG) published the first guideline for optimal diagnosis and treatment of GIST in Korea. As the second version of the guideline,we herein have updated recent clinical recommendations and reflected changes in diagnosis, surgical and medical treatments for more optimal clinical practice for GIST in Korea. We hope the guideline can be of help in enhancing the quality of diagnosis by members of the Korean associate of physicians involving in GIST patients’ care and subsequently in achieving optimal efficacy of treatment.

계약상 부작위청구권의 회생채권성·파산채권성에 관한 연구 -공익채권성·재단채권성에 대한 검토를 겸하여

강윤구 사법발전재단 2023 사법 Vol.1 No.65

이 글은 그동안 채무자 회생 및 파산에 관한 법률(이하 ‘채무자회생법’이라 한다)상 회생채권 또는 파산채권(이하 통틀어 ‘도산채권’이라 한다)으로 인식되지 않았던 부작위청구권의 도산채권성을 검토하는 것을 주된 목적으로 한다. 그와 함께 부작위청구권이 채무자회생법상 공익채권 또는 재단채권에 해당할 수 있는지 여부 또한 아울러 검토한다. 이 글의 결론은 다음과 같다. 첫째, 채무자회생법 제118조 제1호, 제423조(이하 법명의 언급 없이 인용하는 조문은 모두 채무자회생법의 조문이다)의 도산채권의 요건인 ‘재산상의 청구권’은 ‘채무자의 재산적 이익과 관련이 있는 청구권’으로 넓게 해석하여야 한다. 이러한 해석에 의하면, 부작위청구권은 ① 채무자의 재산적 이익과 관련이 있고, ② 금전적 평가가 가능하며(제137조, 제426조 제1항), ③ 공익채권 또는 재단채권에 해당하지 않으면, 제118조 제1호의 회생채권 또는 제423조의 파산채권이 된다. 그에 따라 회생채권이 되는 부작위청구권은 면책(제251조) 및 회생계획에서 권리변경(제252조)의 대상이 되고, 파산채권이 되는 부작위청구권은 배당(제505조 이하) 및 면책(제566조)의 대상이 된다. 둘째, ‘재산상의 청구권’에 대한 위의 해석론에 의할 때, 부작위청구권은 공익채권(제179조 제1항 제5호, 제7호) 또는 재단채권(제473조 제4호, 제7호)이 될 수 있다. 특히 쌍방미이행 쌍무계약에서 채무자에 대한 부작위의무가 부여되었다면, 그 부작위의무가 관리인(파산관재인)에게 ‘승계’되지 못하는 때를 제외하고, 부작위청구권은 관리인(파산관재인)의 이행 선택에 따라 제179조 제1항 제7호의 공익채권 또는 제473조 제7호의 재단채권이 된다. The purpose of this article is to examine whether forbearance claims which have not been recognized as rehabilitation claims or bankruptcy claims(hereinafter ‘insolvency claims’) under the Debtor Rehabilitation and Bankruptcy Act(hereinafter ‘DRBA’) can be insolvency claims. Along with this, this article also examines whether forbearance claims can be considered as priority claims or estate claims under the DRBA. The conclusion of this article is as follows: First, the requirement of “property claims” under Article 118 Subparagraph 1 and Article 423 of the DRBA(all provisions quoted below refer to provisions of the DRBA) should be interpreted as “claims related to the debtor’s property interest”. Under this interpretation, forbearance claims constitute rehabilitation claims under Article 118 Subparagraph 1 or bankruptcy claims under Article 423 if they are ① related to the debtor's property interest, ② capable of being evaluated monetarily under Article 137 or 426 Paragraph 1, and ③ not considered as priority claims or estate claims. Accordingly, forbearance claims which constitute rehabilitation claims are subject to discharge(Article 251) and alteration of rights under the rehabilitation plan(Article 252), and forbearance claims which constitute bankruptcy claims are subject to dividends(Article 505 et seq.) and immunity(Article 566). Second, according to the above interpretation of “property claims”, forbearance claims can be priority claims(Article 179 Paragraph 1 Subparagraphs 5 and 7) or estate claims(Article 473 Subparagraphs 4 and 7). In particular, if the debtor should obey a duty of forbearance in an executory contract, except in cases where the obligation cannot be “transferred” to the custodian(trustee), a forbearance claim constitutes a priority claim under Article 179 Paragraph 1 Subparagraph 7 or an estate claim under Article 473 Subparagraph 7 depending on the custodian(trustee)’s choice of performance.

Evaluation of NH3 emissions in accordance with the pH of biochar

강윤구,이재한,천진혁,윤여욱,오택근,성좌경 충남대학교 농업과학연구소 2021 Korean Journal of Agricultural Science Vol.48 No.4

Nitrogen (N) is the most important element during the process of plant growth, and the quality of crops varies depending on the amount of nitrogen present. Most of the nitrogen is used for plant growth, but approximately 10 - 20% of Nitrogen is carried away by the wind in the form of NH3. This volatilized NH3 reacts with various oxides in the atmosphere to generate secondary particulate matter. To address this, the present study attempts to reduce NH3 occurring in the soil using biochar at a specific pH. Biochar was used as a treatment with 1% (w·w-1) of the soil, and urea was applied at different levels of 160, 320, and 640 kg·N·ha-1. NH3 generated in the soil was collected using a dynamic column and analyzed using the indophenol blue method. NH3 showed the maximum emission within 4 - 7 days after the fertilizer treatment, decreasing sharply afterward. NH3 emission levels were reduced with the biochar treatment in all cases. Among them, the best reduction efficiency was found to be approximately 25% for the 320 kg·ha-1 + pH 6.7 biochar treatment. Consequently, in order to reduce the amount of NH3 generated in the soil, it is most effective to use pH 6.7 biochar and a standard amount (320 kg·N·ha-1) of urea.
