        초등학교 교실의 창호 리모델링을 통한 기밀성능 개선 및 PM2.5 유입 차단 효과

        이주원,강경모,김태연 대한건축학회 2023 대한건축학회논문집 Vol.39 No.6

        When classrooms are sealed shut, the level of PM2.5 infiltration is largely influenced by the effectiveness of airtightness. This study aims toevaluate the airtightness performance by remodeling the windows on the outdoor side, a primary source of PM2.5 inflow, in four classroomsin Korea. These classrooms, with a floor area of 65.6m2 and a volume of 170.6m3, are located adjacent to the same corridor. To evaluateairtightness performance, the main methods utilized were the Blower door test and the calculation of penetration factors through indoor andoutdoor measurements of PM2.5 and CO2. The results demonstrated that, on average across the four classrooms, the ACH50 and ELA,calculated using the Blower door test, decreased by 5.8% and 10.1%, respectively. Additionally the average penetration factor for the fourclassrooms decreased by 14.6%. Furthermore, continuous monitoring of PM2.5 in the classroom with the weakest airtightness performancerevealed an impressive 38.8% decrease in the I/O ratio. 사람들의 실내에 머무르는 시간이 늘어남에 따라, 실내 미세먼지 관리의 중요성이 증가하고 있는 추세이다. 특히, 미세먼지에 민감한 성장기 학생들이 주로 머무르는 학교 교실 내 미세먼지 농도 관리는 더욱 중요시된다. 본 연구는 초등학교 4개 교실의 노후 외기 측 창호를 환기설비가 부착된 창호로 리모델링 하여 기밀성능의 향상 및 외기 미세먼지의 침투 정도를 정량적으로 분석하였다. 연구 결과, 기밀성능의 주요 지표인 ACH50 및 ELA는 각각 5.8%, 10.1% 감소하였으며, 침투계수는 14.6% 가량 감소하였다.

        재정신청 기각결정이 확정된 사건에서 소추 제한의 예외 사유인‘다른 중요한 증거를 발견한 경우ʼ의 의미- 대법원 2018. 12. 28. 선고 2014도17182 판결 -

        이주원 법조협회 2019 法曹 Vol.68 No.4

        Criminal Procedure Act section 262 (4) proviso stipulates "where a decision rejecting an application for adjudication becomes final and conclusive, it may not be subject to public prosecution, except where any other important evidence is discovered later". As regards the meaning of 'where any other important evidence is discovered later', the Supreme Court Decision 2014Do17182 decided December 28, 2018, adopted a strict stance interpreting as follows: "It means that there is sufficient evidence to prove guilt beyond a reasonable doubt by adding newly discovered evidence to the evidence already adduced at the time of the decision rejecting an application for adjudication. It does not include evidence necessary only to the extent for a criminal procedure protecting the rights of the crime victims or questioning the justification of a decision rejecting an application for adjudication.“ This is meaningful in that it is the first judicial precedent to explicitly mention the meaning of 'where any other important evidence is discovered later' stated in section 262 (4) proviso. This is in line with the interpretation of the established judicial precedent in terms of 'any other important evidence', constituting an exceptional reason for reinstitution of public prosecution (section 329), in a case where the decision rejects public prosecution as a result of its being withdrawn becomes final and conclusive. In view of protecting the legal stability and certainty of the suspect, as well as the purposive and systematic interpretation in light of legislative history and intent, the narrow interpretation of the subject judgment with a strict approach would be considered reasonable. 형사소송법 제262조 제4항 후문은 “재정신청 기각결정이 확정된 사건에 대하여는 다른 중요한 증거를 발견한 경우를 제외하고는 소추할 수 없다”고 규정하고 있다. 여기서의 ‘다른 중요한 증거를 발견한 경우’의 의미에 대하여, 대상판결은 “재정신청 기각결정 당시에 제출된 증거에 새로 발견된 증거를 추가하면 충분히 유죄의 확신을 가지게 될 정도의 증거가 있는 경우를 말한다. 단순히 재정신청 기각결정의 정당성에 의문이 제기되거나 범죄피해자의 권리를 보호하기 위하여 형사재판절차를 진행할 필요가 있는 정도의 증거가 있는 경우는 여기에 해당하지 않는다.”라고 해석하고 있다(엄격설). 대상판결은 제262조 제4항 후문에 정한 ‘다른 중요한 증거를 발견한 경우’의 의미에 대해 명시적으로 판시한 최초의 대법원 판결이라는 의의가 있다. 이는 공소취소에 의한 공소기각의 결정이 확정된 사건에서 재기소 제한의 예외사유인 ‘다른 중요한 증거’의 해석에 대한 기존 판례의 확립된 태도와도 그 맥락을 같이 한다. 피의자의 법적 안정성 보호의 관점에서는 물론, 입법연혁과 입법취지를 고려한 목적론적 해석 및 체계적 해석 등 여러 다양한 관점에서 보더라도, 대상판결의 이와 같은 엄격한 제한해석은 타당한 결론이라는 것을 논증하고자 하였다.

      • 分娩方法이 新生兒黃疸에 미치는 影響에 對하여

        李柱元,李鉉金 고려대학교 의과대학 1979 고려대 의대 잡지 Vol.16 No.3

        The indirect hyperbilirubinemia, regardless of the cause, is potentially toxic to the newborn brain, it must be dealt with aggressively terms of prevention, early detection and specific theraphy. Present study was carried out to determine the influence of delivery method on the neonatal jaundice, a total of 672 cases of icteric infants were studied who were born at the Korea University Hospital during the period from April 1976 to September 1978. The results obtained were summarized as follows. 1. Of 2,323 deliveries, the incidence of neonatal jaundice was 28.9% and significant influence of delivery method on the neonatal jaundice was observed (x²=64.69, p<0.0l). The incidence of neonatal jaundice was signigicantly higher (p<0.01) in both infants born by cesarean section and breech delivery and slightly higher but not significant (p>0.05) in vacuum and forcep deliveries than normal. 2. By increasing gestational age, the incidence of neonatal jaundice has became decreased. The infants born before 36 weeks gestation showed significantly high (p<0.01) incidence of hyperbilirubinemia and low in infants born after 42 weeks of gestation but not significant (p>0.05). 3. The weights of newborn infant were closely related with neonatal jaundice. The incidence of hyperbilirubinemia in infants with birth weight below 2.5 ㎏ revealed significantly high and in infants with birth weight above 3.5 ㎏, revealed relatively low. 4. Neonatal jaundice was found during the 2nd and 4th day of life and there was no significant influence of delivery method upon the time of appearance of hyperbilirubinemia. 5. The majority of cases (77. 68%), had serum bilirubin level below 15㎎/100㎖. Higher level was seen in both forceps and breech delivery group while in cesarian section and vacuum delivery group showed relatively low.

        An Inference of Plot Design Method Applied to Pavilions in the Rear Garden of Changdeokgung Palace as World Cultural Heritage

        이주원,허근영 인간식물환경학회 2023 인간식물환경학회지 Vol.26 No.3

        Background and objective: It is necessary to study traditional plot design methods or manners that the engineers in JoseonDynasty were inferred to have conventionally applied to garden spaces or buildings. This study aimed to infer a conventionalplot design method practiced by the engineers who created pavilions in Joseon Dynasty. Methods: The four pavilions were selected, whose original design drawings or documents are still unavailable to reveal themethod or manner. The actual measurement plot design layouts measured and drawn on the spot by Cultural HeritageAdministration (CHA) were analyzed. A geometrical approach was adopted to infer a method that drew the plot designlayout on the ground using only non-gauged rulers (or strings). In the analysis, basic figure frames such as circles or lineswere overlaid on the actual measurement drawings, and whether they matched was checked. Then, we inferred thesequential processes of the plot design method to implement the layout on the paper or the ground. Results: It was inferred that the plot design layouts of the four pavilions might have the same method. The results suggestedthat the engineers in Joseon Dynasty, without accurate numeric scale bars or protractors, might apply a geometricalmethod to determine the position of each pavilion pillar with the figures and intersections created in composing twoidentical circles overlapping by the radius. Two drawing processes implemented by the method inferred to reproduce thelayout of Buyongjeong pavilions with a complex structure coincided with the actual measurement plot design drawing. Conclusion: The result could infer a plot design method and process applied to the four pavilions in the Rear Garden ofChangdeokgung Palace in Joseon Dynasty. It may be a drawing method using string as a numeric scale bar or protractor,which could be used to interpret and reproduce the plot design of traditional Korean garden pavilions built in Joseon Dynasty.

        웹 크롤링을 활용한 상수도 수질 만족도에 관한 감성어 지수 분석

        이주원,최용준,남숙현,김은주,신용현,황태문 한국수처리학회 2023 한국수처리학회지 Vol.31 No.5

        . Owing to recent water accidents, consumers' distrust of tap water and their reluctance to use it have continued. Accordingly, in this study, we analyzed tap water-related data mentioned on social media before and after water quality accidents (red-colored water and larvae issues) to identify consumers' perceptions. To achieve this, a database was built for the data collected through web crawling, and a three-stage customized sentiment lexicon was created: positive, negative, and neutral. Sentiment analysis was then performed using the manufactured sentiment lexicon, and the emotional index was evaluated to predict satisfaction with tap water by calculating the ratio of positive, negative, and neutral words from the analysis results. In the case of red water, the average values of the emotional index before and after the occurrence were calculated as 77.6 and 73.5, respectively, and the lowest value at the time of the event of red water was 59.76, which was lower than the average. For the case of larvae, it was confirmed that the average value before and after the accident was 82.2, and the lowest value during the occurrence period was 58.74. According to these results, it would be possible to monitor any changes in the emotional index value and identify events early in the case of an outlier. In this respect, a method of using the analyzed emotional index as an evaluation index for satisfaction was proposed. If this evaluation technology is reflected in the survey methodology, it is expected that it could be used as an effective countermeasure to respond quickly in an accident and improve citizens' satisfaction with tap water.

        A Clausal Analysis of Resultative Constructions with X-key: Evidence from Corpus and Experiments

        이주원,오은정,송상헌 서강대학교 언어정보연구소 2018 언어와 정보 사회 Vol.35 No.-

        Quite a few prior studies have classified the Korean resultative constructions into predicative resultatives and clausal resultatives. However, the current study argues that all the resultative constructions with X-key belong to the category of clausal resultative construction. This implies that X-key forms a fully saturated clause (not object control), in which the nominative subject of the secondary predicate can be omitted since Korean is a pro-drop language. We present corpus data and experimental results to reveal the existence of pro-drop in the resultative constructions. The linguistic findings are also consistent with the prediction of the pro-drop analysis: various kinds of resultative predicates can appear in the resultative constructions.

        An Experimental Study of ResultativeConstructions with X-key

        이주원,오은정,송상헌 한국중원언어학회 2018 언어학연구 Vol.0 No.49

        In this article we present experimental evidence supporting the two syntactic hypotheses regarding Korean resultative constructions with X-key proposed in Lee (2016): (i) the resultative predicate, X-key, is syntactically an adverb (not an adjective), and (ii) X-key or the result phrase headed by X-key is a complement of the main verb in a resultative sentence. First, we provide a set of experimental results about resultative constructions with Adj(ective)-key with respect to the two syntactic properties, and then those about resultative constructions with V(erb)-key. In the current study, we conducted the acceptability judgment testing on a comprehensive scale using the 5-point Likert scale task and the binary Yes/No task. 264 university-level students participated in the current experiment (132 for each experimental task). We analyzed the experimental results using the statistical techniques in a quantitative way, including the T-test, ANOVA, and Fisher Yates Exact test. We argue that the experimental results empirically support the adverbial complement analysis of Korean resultative constructions with X-key.
