Ethanol의 低溫心臟에 對한 抗細動作用에 關한 硏究

朴廷烈,李聖行 慶北大學校 醫科大學 1974 慶北醫大誌 Vol.15 No.1

This experimental study was performed to clarify the antifibrillatory effects of intravenous infusion of ethanol upon hypothermic hearts. Thirty six mongrel dogs were anesthetized with thiopental sodium and were ventilated with mechanical respirator throughout the experiment. Ethanol, 2.0g/kg, diluted with 5% dextrose solution was intravenously administered in divided doses for the expermental dogs and same amount of 5% dextrose solution for control dogs. Animals were cooled with ice water and rewarmed with hot water. Heart rates and cardiac arrhythmia were checked by ECG. Central venous pressure, right ventricular and pulmonary arterial pressures were measured by means of cardiac catheterization. Animals were divided into two groups. Group 1. Twenty dogs were cooled until death. Among those, 10 experimental dogs were infused ethanol intravenously. Group 2. Sixteen dogs were cooled down to body temperature of 20℃, when cardiac inflow and out-flow were occluded for the period of 15 minutes. Then rewarmed the animals. The results were as follows. 1. Heart rates, arterial pressure, right ventricular and pulmonary arterial pressures were markedly decreased during the period of cooling. Ethanol infusion showed no significant influence upon those decreases. 2. Central venous pressure increased to the level of right heart failure of the cooled animal, and ethanol revealed no protective action on cardiac impairment. 3. In group 1, 10% of ventricular fibrillation was seen among the ethanol infused dogs while 30% of ventricular fibrilltion among the control group. In group 2, there was no significant difference of ventricular fibrillation between ethanol and control groups. 4. Ethanol blood level at 20℃ of body temperature was 636mg%. 5. It was suspected that ethanol failed to protect the hypothermic heart from ventricular fibrillation when cardiac inflow were occluded for the 15 minutes of period.

근로자와 기업문화 수준을 통한 일과 삶의 조화(Work-Life Balance) 측정

박정열,손영미 한국여가문화학회 2005 여가학연구 Vol.3 No.2

주40시간 근무제의 단계적 도입에 따라 사회 전반에 걸쳐 여가와 삶의 질에 대한 관심이 고조되고 있다. 이러한 시대적 변화에 발맞춰 서구 각국에서는 ‘일과 삶의 조화’ 정책이 21세기 인사, 조직 관리의 핵심 화두로 떠오르고 있다. 이에 본 연구는 근로자와 기업의 일과 삶의 조화 수준을 측정함으로써 현재 우리나라 근로자와 기업들의 실태를 파악하고, 이를 통해 향후 ‘일과 삶의 조화’와 관련한 후속 연구들의 기초적인 자료를 제공하기 위한 의도에서 기획되었다. 일과 삶의 조화 실태 조사를 위해 본 연구에서는 개인차원과 기업차원의 일과 삶의 조화 수준으로 나누어서 측정하였다. 그 결과를 살펴보면, 개인차원과 기업차원 모두 일과 삶의 조화 수준이 매우 낮은 것으로 나타났다. 일과 삶의 조화 수준을 측정한 문항들의 타당도를 살펴보기 위해 근로자의 일과 삶의 조화 수준과 생산성 관련 변수와의 관계를 살펴 본 결과, 일과 삶의 조화가 생산성과 관련된 여러 요인에 영향을 미치고 있음 확인할 수 있었다. 끝으로 본 연구결과의 활용 방안에 대해 논의하였다.

Generating Multilingual Text

박정열 경희대학교 언어정보연구소 2007 언어연구 Vol.24 No.1

This paper explores a multilingual generation system in the context of machine translation. France Télécom's third-generation rule-based machine translation engine use semantic graphs as an interlingual representation. We show the detailed working process from an interlingual semantic representation to generating multilingual text as a target language: generating proto-trees (quasi-syntactic trees) from a semantic representation, generating unordered syntactic trees from proto-trees, word ordering, and ranking in generated text. We propose a robustness test which we refer to as a transparency test to verify not only the generativity of our system but also the expressivity of the interlingual semantic representation.

A Korean Learner Corpus and Its Features

박정열,이정희 사단법인 한국언어학회 2016 언어학 Vol.0 No.75

In this paper, we present a Korean learner corpus and aim to find features to characterize this corpus. The corpus is based on an open writing test of Korean learners (beginners, intermediate and advanced students) with various topics and were manually evaluated and scored. We explore several types of features in the learner corpus by starting with the pre-processing of Korean sentences. Some features are automatically measured using parts of speech tagging which concerns the number of tokens and the correct use of Functional morphemes. Syntax-related features and topic-related features are measured while using the automatic syntactic parsing and statistical language models. These features can be used for language proficiency identification and other learner corpus related applications that make use of machine learning techniques.

Is it time to change surgery for early-stage low-risk cervical cancer to simple hysterectomy?

박정열 대한부인종양학회 2024 Journal of Gynecologic Oncology Vol.35 No.2

Radical hysterectomy has long been a standard surgical procedure for early-stage cer vicalcancer. About 80% of early-stage cer vical cancer can be treated with radical hysterectomy,and the sur vival rate after radical hysterectomy is approximately 80% or more [1]. However,since urinar y dysfunction and defecation dysfunction occur in around 40% of patientsafter radical hysterectomy, a decrease in quality of life has long been a problem [2]. Tocomplement this, a ner ve-sparing radical hysterectomy procedure has been proposed, butalthough this is a ver y reasonable surgical procedure in theor y, it is not yet clear whether ithelps reduce morbidity and quality of life [3]. Another method is to find a low-risk groupin which the risk of parametrial metastasis is negligible and sufficient tumor-free resectionmargin can be secured with simple hysterectomy and to omit parametrectomy [4]. Studiescomparing simple hysterectomy and radical hysterectomy have been discouraged due toconcerns about the decrease in sur vival rate that will occur if parametrectomy is omittedin cer vical cancer. The SHAPE trial was the first prospective randomized controlled trialcomparing simple hysterectomy and radical hysterectomy in low-risk early-stage cer vicalcancer, and demonstrated that simple hysterectomy was non-inferior to radical hysterectomyin terms of pelvic recurrence rate at 3 years [5]. In the SHAPE trial, pelvic relapse free sur vival was initially the primar y endpoint, but due toinsufficient event occurrence, it was changed to pelvic recurrence rate at 3 years. The pelvicrecurrence rate was shown to be non-inferior, but in fact, exptrapelvic recurrence and overallrecurrence were more frequent in the simple hysterectomy group, and deaths due to cer vicalcancer were also more frequent in the simple hysterectomy group even though positive lymphnode, positive resection margin and positive parametrium were more in radical hysterectomygroup. The total recurrence rate including pelvic and exprapelvic recurrence after simplehysterectomy was 4.3% in SHAPE trial. In ConCer v trial that included patients with negativeresection margin after loop electrosurgical excision procedure or conization, the totalrecurrence rate was 3.5% after simple hysterectomy in low-risk early-stage cer vical cancer[6]. The total recurrence rate was 2.9% after radical hysterectomy in SHAPE trial. It was 0.7%in all stage IB1 cer vical cancer after open radical hysterectomy in LACC trial [7]. Many studygroups are expected to conduct follow-up studies evaluating less radical surger y in the future,and exptrapelvic recurrence should also be included as a primar y endpoint. The definition of low-risk early-stage cer vical cancer is same with the definition of low-risk disease for parametrial involvement. These criteria var y somewhat among studies, butinclude usual type histology (squamous cell carcinoma, adenocarcinoma, and adenosqumous carcinoma), tumor <2 cm, depth of invasion <10 mm, negative lymphovascular spaceinvasion, and negative lymph node metastasis [4]. In the ConCer v trial, adenocarcinoma waslimited to grade 1 and 2 [6]. In the SHPAE trial, cases with invasion depth of less than 50%on magnetic resonance imaging (MRI) were also included. Instead, lymphovascular spaceinvasion was not considered in the SHPAE trial. In fact, it is inaccurate to diagnose low-riskdisease using these conditions before surger y. It is difficult to accurately measure tumorsize and lymphvascular space invasion before surger y, and diagnosing stromal invasiondepth with MRI is also ver y inaccurate. In SHAPE trial, parametrial involvement was notedin 1.7% of patients after radical hysterectomy, but no one had parametrial involvement insimple hysterectomy. The parametrial involvement might be missed in simple hysterectomygroup because parametrectomy was not performed. To diagnose low-risk early-stage cer vicalcancer, more accurate method is needed. The SHAPE trial did not clearly specif y ...

일상재구성법을 통한 경력단절 여성의 일상생활과 정서경험 분석

박정열,손영미 여가문화학회 2015 여가학연구 Vol.13 No.2

This study was conducted to investigate what was career interrupted women’ main activities in everyday life and what and how they felt in those activities. 724 married career interrupted women were participated in this DRM(day reconstruction method) research. The major findings of this study were as follows. While they were more inclined to experience positive emotion, they were less inclined to experience negative emotion. Secondly, only a few of participants selected ‘learning’, ‘job hunting activities’ among everyday activities. Worst of all, it was revealed that they felt anxious, stressful and worried as they were doing job hunting activities. Thirdly, the most frequent activities such as cooking, cleaning, childcare etc were showed to be felt less positive and more negative emotions. Forth, participants experienced different positive and negative emotions depending on person(husband, children, friend etc). It was worthy of notice that their children were the objects that they had an ambivalent emotion that is affective and confident as well as tired, bored and anxious. Finally, It was revealed that am 8-11 and pm 6-8 were burnout time zones where participants experienced the most negative and the least positive emotion all over the day. 본 연구는 일상재구성법을 활용하여 경력단절 여성의 일상생활의 주요 활동(가사 및 육아, 여가, 학습 및 구직활동 등)을 탐색하고, 정서경험의 질을 측정하는 것을 목적으로 한다. 이를 통해 이들의 현재의 행복수준을 진단하고, 재취업과 관련한 시사점을 도출하고자 하였다. 직장을 그만 둔지 1년 이상 된 30대, 40대, 50대 경력단절 여성 724명의 자료가 분석되었으며, 그 결과는 다음과 같다. 먼저, 경력단절 여성들은 평상시 긍정적인 정서수준이 높고, 부정적인 정서수준은 낮은 것으로 나타났다. 다음으로, 경력단절 여성 중 ‘교육 및 학습’, ‘구직활동’에 참여하는 여성이 극소수인데, 참여하는 여성들도 학습활동이 구직활동으로 이어지지 못하는 경향을 보였다. 구직활동은 경력단절 여성에게 상당한 걱정과 긴장, 스트레스를 주는 활동이었다. 셋째, 경력단절 여성들은 음식준비, 청소, 자녀보살피기 등의 활동에 가장 빈번하게 참여하면서도 그것에 대해 긍정 정서는 적게 느끼고, 부정 정서는 더욱 느끼는 경향을 보였다. 넷째, 주요 상호작용 대상자에 따라 느끼는 정서가 서로 다름을 알 수 있었다. 특히 자녀는 애정/우호, 유능/자신감을 주는 대상임과 동시에 피곤함, 지루함, 긴장/스트레스를 느끼게 하는 부정적인 정서대상으로 드러나 가장 양가적인 감정을 느끼는 대상이었다. 마지막으로, 남편의 출근과 자녀의 등교를 위해 바쁘게 움직여야 하는 8시~11시, 저녁식사를 준비하고 정리해야 하는 저녁 6시~8시가 경력단절 여성이 가장 높은 수준의 정서노동을 하는 시간대임을 확인할 수 있다.
