김기택 시에 나타난 육식의 윤리와 아이러니

홍기정(Hong, Ki-Jung) 문학과환경학회 2013 문학과 환경 Vol.12 No.1

In these days, meat diet is problematic issues in terms of health, environmental and ethical issues. Poets in Korea focus the meat diet issue as a life-threatening problem (bioethics), the topics they are interested in is how to deal with the ethical pressure after eating living animals. The poet, Kim, Ki-Taik, criticizes unethical human behaviors for eating meats. Once people consider animals just for a menu, we make ourselves light of the life, which might make feeling of guilty. Continuously, that feeling might link with the negative logics about meat diets. However, Kim, Ki-Taik does not go to that negative logic but he also agrees we as a human instinctually want meats. Ironically, his poetry point out the meat diet’s unethical aspects which cause a sense of guilty but people as a human have no choice but to accept the fact that people eat meats. Thus, Kim, Ki-Taik claims that these ironies are the same as human’s proof of guilt. He also insists that it is inappropriate for human to take the evidence of crime, even though human natural is fundamentally evil, he believes. He tries to interpret the irony of meat diet metaphysically, to understand the reconciliation between life and death.

Background/Aims: Rectal carcinoid tumors can be resected with endoscopy, and it is important to assess their prognostic factors. We evaluated the potential of Ki-67 expression as a prognostic factor in rectal carcinoid tumors. Methods: We retrospectively reviewed the medical records of 37 patients with rectal carcinoid tumors who got endoscopic resection from January 2001 to January 2011 at Inje University Seoul Paik Hospital. We analyzed their endoscopic and histologic findings, Ki-67 expression, clinical outcome, and prognosis. Results: The mean age (±SD) of the patients was 56.3±10.7 years, and the male : female ratio was 3.6:1. The mean tumor size was 0.5±0.4 cm, 33 patients showed grade 1 tumors (89.2%) and the average Ki-67 expression was 0.7±1.2%. Thirty five patients underwent endoscopic mucosal resection, and two required endoscopic submucosal dissection. Eight patients had positive margins after resection, but no cases of lymphovascular invasion were identified. The median follow-up duration was 21.4±25.4 months, and no recurrences were observed. Conclusions: In low grade rectal carcinoid tumors which are lack of central depression on colonoscopy, the expression of a molecular marker of malignant potential, Ki-67, was low. Therefore, endoscopic resection seemed to be a safe and effective treatment for these tumors.

Objective: This study aims to analyze that specific prognostic factors such as Ki-67 value, histologic grade, pathology type, and cancer stage can affect controlled ovarian stimulation outcomes(COS) for fertility preservation in women with breast cancer. Methods: This retrospective cohort study included 92 patients with breast cancer aged 21-44 who underwent COS from August 2012 to April 2020, excluding patients with previous gonadotoxic therapy history. All COS cycles were conducted letrozole-combined random start GnRH antagonist protocol. COS outcomes were compared according to prognostic factors;Ki-67 (< 30% vs. ≥ 30%), histologic grade (low vs. high), and pathologic type (intraductal carcinoma(IDC) vs. triple-negative breast cancer(TNBC)), and cancer stage (early (I, II) vs. advanced (III, IV)). Multivariate analysis was also conducted to find any parameter that can impact over 10 mature oocytes acquisition. Results: Among the 92 patients, 42 were Ki-67≥30% compared to 49 of Ki-67<30%. The number of oocytes, and initial mature oocytes were comparable between Ki-67<30% and ≥30 group. The maturation rate was significantly higher in Ki-67≥30% group than Ki-67<30% group (57.4±36.8% vs. 44.8±28.3%, p=0.041). The same results were drawn when divided according to IDC or TNBC. The maturation rate was significantly higher in TNBC than the IDC group (73.0±17.6% vs. 47.0±28.1% p=0.001). However, the histologic grade or stage did not show any difference in COS outcomes between high and low grade or early and advanced stages. With multivariate analysis, age and AMH are parameters associated with the acquisition of over 10 mature oocytes (OR 0.863, 95% CI [0.755-0.987], OR 1.408, 95% CI [1.145-1.732], respectively). Conclusion: Either Ki-67 or pathologic type can be a potential reliable marker for predicting COS outcome, especially maturation rate. Further study with larger sample size with specific conditions is necessary to clarify the correlation between breast cancer prognostic factors and COS outcomes.

To examine the change of blood lactate concentration, EMG power spectrum, and Torque during fatiguing isokinetic contraction and recovery phrase, 6 sprinters performed maximal isokinetic knee extension at angular velocity of 3.14 rad.sec??(180°sec??) to 75% decreasing point (25%PT) using CybexⅡ system. In exercise phase, there was significant correlation between the decrement of peak EMG and median frequency and that of torque, and decrement of torque was greater than that of EMG . In recovery phase, EMG was restituded as normal value rapidly in a minute, but torque was restituded more slowly, and blood lactate concentration increased gradually from 50%PT to 3 minute after recovery. As a result of this study, it is suggested that muscle fatique due to decreasing of metabolic substrate and accumulation of metabolic products in peripheral site of muscle, and that inhibitory factors act neuromuscular junction in the end of exercise from rapid restitution of EMG in recovery phase.

In Clearfil SE Bond group, esterase solution lowered bond strength more than PBS(p>0.05). Collagenase solution lowered bond strength more than esterase solution(p>0.05) and PBS(p<0.05).

THE DEVELOPMENT OF THE EM-<TEX>$200^{TM}$</TEX> GAS-FILLED AFFF FIRE EXTINGUISHER FOR AUTOMATIC FIRE SUPPRESS10N SYSTEMS IN THE ENGINE COMPARTMENT OF AUTOMOBILES

Jung,Ki-Chang,Kim,Hong,Kang,Young-Goo 한국화재소방학회 1997 한국화재소방학회 학술대회 논문집 Vol.1997 No.-

In recent years, the number of vehicle fires, as well as the number of motor vehicles, has been increasing rapidly. Therefore, several types of automatic fire suppression systems for the engine compartment of automobiles have been developed to extinguish automobile fires, and most of these systems use halon 1301 as a fire extinguishing agent. Due to environmental concerns, the phase-out of halons has been announced, so now there is a need to replace halon 1301. For this, a 1,1,1,2,3,3,3-heptaflouropropane (HFC-227ea, FM-<TEX>$200^{TM}$</TEX>) gas-filled Aqueous Film- Forming foam (known as AFFF) extinguisher was devised even though air foam extinguishers could be used. This is because the air in the foam bubbles is a source of oxygen required for the combustion reaction. It can be surmised that it is possible to increase the fire extinguishing efficiency of AFFF by filling in foam bubbles with a gaseous extinguishing agent. The best choice is the FM-<TEX>$200^{TM}$</TEX> gas-filled AFFF, Which has the maximum expansion ratio of 62:1. This makes it possible for the expanded foam to rapidly fill the engine compartment.

The oral bioavailability of itraconazole is variable and low in fasting state. This is mainly due to the low solubility of this drug. Bioavailability can be improved by changing the formulation and it is general that the liquid preparations show greater bioavailability than the solid dosage forms such as tablets and capsules do. Benzyl alcohol-water binary mixture showed the excellent solubilizing capacity for itraconazole but the release of the drug from the preparation needs to be enhanced. In this study, various nonionic surfactants and hydrophilic polymers, poloxamers, were screened to investigate their effects on the release of itraconazole from the liquid preparations. Poloxamer 407 showed the most enhancing effect on the drug release and the release rate was proportional to the amount of poloxamer 407 added. A liquid preparation of itraconazole, consisting of benzyl alcohol/water/poloxamer 407 ternary solvent system, released more than 80% of the total drug amount at 5 min and showed the possibility of a new formulation development.

일반적으로 전과정평가는 제품시스템의 전과정에서 사업장으로 들어오거나 사업장에서 배출되는 물질들을 정량화하고 이들이 외부환경에 미치는 잠재적인 영향을 평가하는 환경성평가 도구이다. 하지만 사업장에서 배출되는 물질들은 작업장의 외부환경 뿐만 아니라 작업환경에도 영향을 미친다. 이에 따라 본 연구에서는 전과정평가의 기본골격에 작업환경을 통합하여 평가할 수 있는 방법론을 개발하였다. 본 방법론에서는 서로 다른 특성을 가지는 작업환경과 외부환경의 영향을 적절하게 통합하기 위하여 시스템경계와 범주지표의 수준을 동일하게 맞출 수 있는 일반요건을 설정하였다. 시스템경계의 수준을 동일하게 하기 위하여 산업연관분석(IOA)기법을 도입하였고, 범주지표의 수준을 동일하게 조정하기 위하여 DALY, PAF, LWD와 같은 종말점 수준의 범주지표를 활용하였다. 개발한 방법론에 대한 이해를 돕기 위하여 국내에서 생산된 석유화학제품을 중심으로 사례연구를 수행하였다. A conventional life cycle assessment (LCA) framework mainly evaluates the environmental impacts associated with inputs and outputs from/to external environment of a product system. However the inputs and outputs generated from a facility influence not only the external environment but also the working environment. Therefore, this study developed the methodology that could integrates the working environment into a conventional LCA framework. It established the general requirements for adjusting the levels of the system boundary and category indicators in order to integrate appropriately the impacts of both the working environment and the external environment which have the different characteristics. Thus, this study introduced Input Output Analysis (IOA) technique in order to extend the system boundary to the life cycle of a product system, and applied the category indicator such as the number of Disability Adjusted Life Years (DALY), the Potentially Affected Fraction (PAF) and Lost Work Days (LWD) in order to assess the impacts of end point level. A case study of a petrochemical company in Korea was provided as an example for illustrating the feasibility of the methodology developed in this study.
