송현아 ( Song¸ Hyunah ),정윤천 ( Jung¸ Yoonchun ) 한국공간디자인학회 2021 한국공간디자인학회논문집 Vol.16 No.7

(연구배경 및 목적) 여의도 시범아파트 단지는 1970년대 초반에 지어질 당시 가장 발전된 건축 계획방법이 적용된 우리나라 최초의 단지형 초고층 아파트로서 역사적인 가치를 지닌다. 2021년 현재 완공된 지 50년이 넘어서는 시점을 넘어서고 있으며, 동시대에 지어진 다른 아파트 단지들과 같이 전면 철거를 통한 재건축 방식이 논의되고 있다. 하지만 여의도 시범아파트 단지는 일반적인 폐쇄형 공동주택 단지와 달리 주변 도시적 맥락과 소통하고 있으며, 빠르게 변화하는 거주민의 삶의 모습을 담을 수 있다는 점에서 건축적 잠재력을 가지고 있다. 따라서 본 연구에서는 여의도 시범아파트 단지의 건축적 가치에 대한 인식을 기반으로 이를 유지하고 보전하기 위한 부분적 리모델링 방식을 통해 도시적 맥락 속 역사적 공동주택 단지가 나아갈 방향을 제시하는 데에 그 목적을 둔다. (연구방법) 현장답사를 통해 일반적인 공동주택 단지와 비교되는 여의도 시범아파트 단지의 특징과 가치를 파악한다. 특히 주변의 도시적 맥락과 교류하는 방식, 단지 계획적 특성, 세대 내부와 복도 공간에서 나타나는 건축공간 이용방식 중심으로 살펴본다. 여기서 발견되는 다양한 가능성을 여의도 시범아파트 단지 리모델링 설계에 적용한다. (결과) 여의도 시범아파트 단지의 리모델링 설계에 적용 가능한 구체적인 설계방안을 다음과 같이 제시한다. 첫째, 단지의 장소성을 확보하기 위해 주변의 여러 도시적 상황과 접하는 경계부에 공유광장을 조성할 것을 제안하고 여기에 거주민과 지역사회가 이용할 수 있는 프로그램을 설정한다. 둘째, 단지의 개방성과 공공성을 확보하기 위해 경계광장과 아케이드 상가 및 공원의 동선을 대지 레벨 상에서 연결한다. 동시에 거주민의 프라이버시와 영역성을 확보하기 위해 주민 전용 데크를 상부에 배치한다. 셋째, 주거공간의 다양성과 지속성을 확보하기 위해 주거공간을 개별 단위 공간으로 해체하여 재구성한다. (결론) 본 연구에서는 여의도 시범아파트 단지에서 발견되는 역사적, 건축적 가치를 보전하고 이를 극대화하는 리모델링 방식을 제안함으로써, 이전의 건축적 형태와 기능 그리고 오랜 시간 동안 단지 내에 축적되어온 유무형의 주거문화를 유지하면서 더 나은 주거환경을 제공할 수 있음을 증명한다. (Background and Purpose) Imagined as the first South Korea’s high-rise ideal urban apartment complex, advanced architectural planning methods and technologies, such as cul-de-sac, central heating and electricity supply systems, elevators and escalators, and fire evacuation systems were employed in the design of the Yeouido Sibum Apartments. As of 2021 a series of discussions regarding reconstruction issues are moving forward, however they only focus on finding ways of elevating its real estate values by introducing a totally new design. However, unlike other apartment complexes built around the same time period, the Yeouiod Sibum Apartments has architectural potentials of accommodating the changing lifestyles of the future residents. Therefore, the purpose of this study is to propose a plan for revitalizing the Yeouido Sibum Apartments by maintaining and preserving its architectural values. (Method) First, by carrying out meticulous on-site analyses as well as collecting materials on previous studies on the history of South Korean apartment complexes, the unique architectural characteristics and values of the Yeouido Sibum Apartments Complex are identified. In-depth studies on its site planning as well the design of the apartment buildings, the public corridors and the individual units are followed. In particular, by carefully studying the structural characteristics of the Yeouido Sibum Apartments, various spatial flexibilities and extensions for the apartment units can be imagined. Afterwards, important case studies are conducted to derive design strategies and sustainable future architectural programs that can be applied to the remodeling process of the Yeouido Sibum Apartments. (Results) First, to maintain the quality of‘placeness’of the Yeouido Sibum Apartments, public squares are proposed at the border areas of the complex meeting with various surrounding urban conditions, and special programs for the residents and visitors are suggested for them. Second, to ensure the quality of‘openess’of the apartment complex, the proposed public squares are connected to the existing arcade space and the public parks on the ground level. By designing an elevated pedestrian deck linking the apartment buildings on an high-level, privacy is secured for the residents. Third, to accommodate the idea of ‘diversity’and‘sustainability’ of the residential units, they are partially remodeled by utilizing existing spatial and structural qualities. (Conclusions) This study identifies the values of the Yeouido Sibum Apartments and suggests ways to maintain and improve its architectural and urban conditions, while accommodating the changing lifestyles of the residents. The results can be seen as a sustainable design method complementing the current redevelopment process of the Yeoudo Sibum Apartments.

Functional analysis of cellular localization and complex formation of protein O-mannosyltransferases in Hansenula polymorpha

Hyunah Kim,Dong-jik Lee,Doo-Byoung Oh,Ohsuk Kwon,HyunAh Kang 한국당과학회 2011 한국당과학회 학술대회 Vol.2011 No.1

Protein O-mannosylation is evolutionarily conserved essential protein modification from bacteria to humans, which is initiated in the ER by protein O-mannosyltransferases (PMTs) that catalyze the transfer of mannose from Dol-P-Man to Ser/Thr residues of secretory proteins. We identified and characterized five PMT subfamily genes, PMT1.1, PMT1.2, PMT2, PMT4 and PMT6 in the thermotolerant methylotrophic yeast Hansenula polymorpha. The hydropathy profile analysis predicts all H. polymorpha Pmt proteins to be integral membrane proteins with multiple transmembrane domains. For confirmation of subcellular localization of HpPmt proteins and characterization of PMT complexes, we constructed a set of HA or FLAG epitope-tagged versions of H. polymorpha Pmt proteins. All the C-terminal epitope-tagged HpPmt proteins were shown to be fully functional in vivo and to localize at the ER/Golgi membrane, except for Pmt6p. The significant sensitivity of Hppmt1.2 strain to the PMT1 inhibitor R3A-1c suggested that HpPMT1.2 might have a minor function redundant with HpPMT1.1. However, co-immunoprecipitation experiments using monoclonal anti-HA or anti-Flag bead revealed the complex formation between HpPmt1.1p and HpPmt2p, but no interaction between HpPmt1.2p and HpPmt2p even in the absence of HpPmt1.1p. The results strongly support the notion that interaction with HpPmt2p is required for the full mannosyltransferase activity of HpPmt1.1p, which plays a major role in O-mannosylation essential for cell wall integrity in H. polymorpha.

Noroviruses (NoV) are the major viral pathogen causing epidemic acute gastroenteritis and outbreaks of foodborne and waterborne illness. During the local festival in Chungnam province, group food poisoning occurred outbreak by NoV infections in Jan 2019. In this study, epidemiological analysis and molecular characterization were conducted such as genotyping, phylogeny. The prevalent genotypes of food poisoning events were NoV GII.3 and GII.17, and NoV GII.3 and GII.17 isolates of this study were completely matched in nucleotide sequence comparison of capsid gene region, respectively. In underground water and stream water, various multiple genotypes of noroviruses were detected including NoV GII.3, GII.8 and GI.4 in aquatic environment of the local festival site. Among 32 worker samples, various NoVs of five genotypes (GI.7, GI.8, GII.3, GII.8, GII.17) were detected in 12 samples and expected to causing NoV contaminated by exposure to groundwater. NoV genotype GII.3, which was detected from groundwater 2, was completely consistent with that of patients and workers. Therefore, groundwater within the local festival site could be main cause of food poisoning event. Because NoV outbreaks are caused by fecal to oral transmission, proper management of sewage purification facilities, groundwater and sanitary toilets is required for many visitors, and efforts are needed to maintain clean environment.

Effects of Hydrogen Plasma Treatment of the Underlying TaSiN Film Surface on the Copper Nucleation in Copper MOCVD

Hyunah Park,임종민,이종무 한국세라믹학회 2004 한국세라믹학회지 Vol.41 No.6

MOCVD is one of the major deposition techniques for Cu thin films and Ta-Si-N is one of promising barrier metal candidates for Cu with high thermal stability. Effects of hydrogen plasma pretreatment of the underlying Ta-Si-N film surface on the Cu nucleation in Cu MOCVD were investigated using scanning electron microscopy, X-ray photoelectron spectroscopy and Auger electron emission spectrometry analyses. Cu nucleation in MOCVD is enhanced as the rf-power and the plasma exposure time are increased in the hydrogen plasma pretreatment. The optimal plasma treatment process condition is the rf-power of 40W and the plasma exposure time of 2 min. The hydrogen gas flow rate in the hydrogen plasma pretreatment process does not affect Cu nucleation much. The mechanism through which Cu nucleation is enhanced by the hydrogen plasma pretreatment of the Ta-Si-N film surface is that the nitrogen and oxygen atoms at the Ta-Si-N film surface are effectively removed by the plasma treatment. Consequently the chemical composition was changed from Ta-Si-N(O) into Ta-Si at the Ta-Si-N film surface, which is favorable for Cu nucleation

Expression of sIx Glutation S-Transferase Genes in Seven Two-Spotted Spider Mite, Tetranychus urticae Koch Strains

Hyunah Kim,Hyun Kyung Kim,Hyun-Na Koo,Gil-Hah Kim 한국응용곤충학회 2014 한국응용곤충학회 학술대회논문집 Vol.2014 No.10

The two spotted mite, Tetranychus urticae Koch, is a global pest, and has developed severe resistance to several types of acaricides. Acequinocyl-resistant strain and bifenazate-resistant strain of T. urticae showed higher relative activity level of glutathion-S-transferases (GSTs) than susceptible strain. Studies of resistance in T. urticae have focused on classical detoxifying enzyme system, such as GSTs. We examined the expression of six GSTs genes in T. urticae belong to five different cytosolic classes, including two in delta, one in omega, one in mu, one in zeta, and one mitochondrial GSTs class, kappa. RT-qPCR results showed that, among these six GSTs genes, the relative expression level of delta 1 was significantly higher in bifenazate-resistant strain than in other strains (susceptible, abamectin, acequinocyl, etoxazole and pyridaben strain). Expression level of the delta 2 was also higher in acequinocyl-resistant strain than in other strains. The elevated GSTs gene transcripts following exposure to acequinocyl, bifenazate might be one of the mechanisms involved in detoxification of these acaricide. These results may be caused by different mechanisms in the resistance development of T. urticae to these two different types of acaricides.

A major concern in exporting agricultural commodities is the introduction or spread of exotic quarantine pests to the new area. To prevent spread of insect pests, various phytosanitary measures are used. In this study, we compared the effect of electron beam and X-ray irradiation on development and reproduction of the two-spotted spider mite, Tetranychus urticae. Eggs, nymphs, and adults were irradiated at target doses of 50, 70, 100, 150, 200, 250, and 300 Gy with electron beam and 10, 20, 30, 50, 70, 100, 150, and 200 with X-ray irradiation. When eggs were irradiated, egg hatching was completely inhibited at 150 Gy of electron beam and 50 Gy of X-ray irradiation. When irradiated to the nymphs, emergence was not affected at all target dose in both electron beam and X-ray irradiation. Hatchability of F1 generation was significantly decreased at 100 Gy of electron beam and 70 Gy of X-ray irradiation. When irradiated to the adults, longevity did not show any differences at all target dose in both electron beam and X-ray irradiation. These results suggest that the effect of X-ray irradiation was more potential than electron beam irradiation.

Use of prosody for ambiguity resolution by Korean ESL speakers

Hyunah Baek 한국언어과학회 2020 한국언어과학회 학술대회 Vol.2020 No.10

Differences in the perception of segmental contrasts by native and non-native listeners have been formalized as the results of language-specific weightings of acoustic cues in their perception grammar (e.g., Escudero & Boersma, 2004). However, less attention has been paid to the weighting of prosodic cues. This study investigated the relative importance of four prosodic cues – duration, pause, pitch, and intensity – in the resolution of syntactic ambiguity by English native speakers and Korean ESL speakers. In a processing experiment, two groups of participants listened to English sentences with relative clause attachment ambiguity (e.g., Jennifer blackmailed the boss of the clerk who was dishonest), differing in the presence/absence of the four prosodic cues for disambiguation. Then, they chose a more appropriate interpretation of the sentence (e.g., Q: Who was dishonest? Choices: the boss or the clerk). The results indicated that English speakers weighted pause and pitch cues heavily than lengthening and intensity, while pause was the only heavily weighted cue for Korean speakers. This is in line with a previous production study, which found that in English, RC attachment is disambiguated by the combination of boundary cues (pause) and head prominence cues (pitch and intensity), but in Korean, the ambiguity is mainly resolved by boundary cues (lengthening and pause) (Baek, 2019). Thus, Korean speakers’ weaker use of pitch compared to English speakers is likely an L1 influence. It suggests that, similarly to segmental cues, prosodic cues are weighted differently across languages, which influences second language sentence processing.

A Journey of Family Law Reform in Korea: Tradition, Equality, and Social Change

( Hyunah Yang ) 서울대학교 법학연구소 2009 Journal of Korean Law Vol.8 No.1

This article reviews fifty years of history of family law reform in Korea with particular emphasis on the most recent and a large-scale revision in March 2005. For this purpose, this article overviews three previous revisions in 1962, 1977, and 1989 from a feminist point of view. History of family law has been tantamount to the history of feminist legal movements, and the feminist legal movements for family law mark the longest history in the legal feminism in Korea. The essay then discusses the revision in 2005, its main bodies, political and social situation. As seen, diverse social sectors of citizens’ movements were mobilized and public sectors such as legislature, administration, and Constitutional Court made this huge change in law, particularly deletion of the family-head system possible. It also discusses the social environment such as rapid changes in birth rate, numbers of family members, rates of divorce and remarriage in South Korea that shaped social context of the legal change. Based upon this analysis, the essay discusses several points about law and society seen through the family law and revision movement. It discusses largely three issues: ‘tradition’ and colonialism embedded in the law; state’s concern on the ‘normalization’ of the family, nature of feminism(s) emerging in the process of revision of the law. Overall, the process of family law revision reveals the uniqueness of feminism and feminist jurisprudence in Korea, and its possibility to be a viewpoint to understand law’s history as well as history through the law.
