10년령의 중성화된 수컷 Poodle이 기흉이 의심되어 내원하였다. 어릴 때부터 기침증상을 보이다가 약 2주 전부터 악화되었으며, 혈액검사 및 요검사에서 유의적인 특이소견은 발견되지 않았다. 흉부 방사선 영상에서 기흉 소견 및 좌측 전엽 부위 기관지의 단절과 고도로 감소된 폐 실질이 관찰되었다. 흉부의 CT 영상 검사에서, 좌측 전엽과 덧엽에서 몇 개의 cyst들과 허탈된 폐가 관찰되었다. 또한 이 부위에서 기관지와 세기관지들은 비정상적인 형태로 끝부분이 가늘어지지 않았으며, 그 외에도 기흉, 기종격, 그리고 피하 기종이 확인되었다. 이러한 영상학적 특징들로부터 기종성 수포의 파열에 의해 발생한 자발성 기흉이 고려되었으며, 그 원인으로는 선천적인 기관지의 이상 또는 기관지 가지의 기형이 고려되었다. 부분적인 폐 덧엽 절제술이 실시되었으며, 좌측 전엽, 우측 중엽, 그리고 덧엽의 저형성이 확인되었고 특히 덧엽에서는 공기가 새고 있는 수포가 확인되었다. 조직병리학적 검사를 통해 기관지 연골 저형성으로 최종 진단되었다. A 10-year-old, castrated poodle dog presented with a cough for 2 weeks, and the cough initially developed since very young age. On radiographs, pneumothorax was noticed by characteristics of radiolucent area without pulmonary markings along the thoracic wall and diaphragm, retracted lung lobes from the thoracic wall and severely decreased volume of the left cranial lung lobe with disconnected bronchus. Computed tomography (CT) findings identified several pulmonary air-filled cysts and collapsed lung with abnormal shape and non-tapered end of bronchus, bronchioles at the accessory lobe and left cranial lobe. Also, pneumothorax, pneumomediastinum and subcutaneous emphysema were found. Imaging diagnosis was the spontaneous pneumothorax caused by ruptured emphysematous bullae associated with congenital bronchial cartilage abnormality or bronchial tree malformation. On surgery, hypoplasia of the left cranial lobe, right middle lobe, and accessory lobe with a bulla where air was leaking was identified. The accessory lobe was partially resected and bronchial cartilage hypoplasia was confirmed by histopathologic examination.

국내 대기업 사회공헌 담당자들이 인식하는 사회공헌 활동의 기대 효과와 PR의 역할에 대한 질적 고찰

김수연(Kim, Soo?Yeon),권지현(Kwon, Jeehyun) 한국광고홍보학회 2017 한국광고홍보학보 Vol.19 No.3

이 연구는 기업의 사회공헌 활동을 위한 PR의 역할과 그 주요 효과를 탐색해 보고자 국내 100대 기업 내 14개 기업 소속 16명의 사회공헌 담당자들과 심층 인터뷰를 진행하였다. 사회공헌 담당자들은 사회공헌 활동의 주요 기대 효과로 브랜드 관리와 위기관리를 들어서 사회공헌 활동을 통한 명성 관리 효과를 가장 주요하게 인식하고 있었다. 사회공헌 활동을 위한 PR의 역할은 ‘주요한 경영적 역할’, ‘커뮤니케이션 역할’, ‘사회공헌 활동의 하위 기능’, ‘관련 없음’의 네 가지로 구분되었는데, 이러한 상반된 인식의 기저에는 PR을 과정으로 이해하는 입장과 PR을 내/외부로 알리는 커뮤니케이션으로 국한해서 이해하는 입장 차가 있었으며 사회공헌 활동을 대외적으로 알려야 하는 당위성에 대한 의견 차도 확인 가능했다. 이 연구는 사회공헌 활동의 기대 효과와 PR의 역할을 국내 대기업 소속 사회공헌 담당자들의 언어로 규명함으로써 그들의 입장과 시각에 대한 실무적 이해를 높이고 사회공헌 활동과 관련한 PR이 나아가야 할 방향을 제시했다는 데 의의가 있다. In-depth interviews with 16 CSR managers representing 14 companies on the 2015 Korean Large Company 100 list were conducted to explore the role of public relations in corporate social responsibility (CSR) activities and CSR effects. CSR managers perceived that public relations plays a significant role in brand management and crisis management related to CSR. They identified four roles regarding the relationship between public relations and CSR: significant management role, communication role, subfunction of CSR activities, and no role. These different perceptions result from CSR managers’ different understandings of public relations. Some understood public relations as a process, while others regarded public relations as a publicity function targeting internal and external publics. Finally, this study is meaningful in that it explores the role of public relations in CSR activities by investigating the practical perceptions of CSR managers.

김수연,이정훈,송제영,김병일,오상근,Kim, Soo-Yeon,Lee, Yeon-Sil,Song, Je-Young,Kim, Byoungil,Oh, Sang-Keun 한국구조물진단유지관리공학회 2017 한국구조물진단유지관리공학회 논문집 Vol.21 No.5

본 연구에서는 지하 콘크리트 구조물의 누수 균열에 사용되는 주입형 누수보수재료의 품질관리 방안으로 규격화된 국제표준 ISO TS 16774, Part 2 Test method for chemical resistance를 이용하여 현재 우리나라 누수보수현장에서 사용하고 있는 주입형 누수보수재료 2계열(합성고무계, 시멘트계), 3종류 씩, 총 9 종류의 보수재료에 대한 지하 콘크리트 구조물이 처한 화학적 환경의 저항 안정성을 연구 검토하였다. 그 결과, 합성고무계는 RG-3를 제외하고, 산에 대한 저항력을 높일 수 있는 재료적 검토가 필요하고, 시멘트계는 수산화나트륨, 염화나트륨에 대한 저항을 높일 수 있는 재료적 검토의 필요성이 확인되었다. 이러한 결과는 콘크리트 구조물의 화학적 환경에서의 보수재료 선정 시 기본 지표로 사용가능 할 것으로 판단된다. 또한, 추후에 연구 개발 되는 보수재료의 품질 향상에 반영할 수 있는 기준 자료의 활용을 기대할 수 있다. In this study, by using the international standards ISO TS 16774, Part 2 Test method for chemical resistance as a quality control method of injection type repair material used for leakage crack of underground concrete structure, the performance requirement against of chemical environment of underground concrete structures for repair materials was tested. For this testing 3 types for each of the 2 classes of repair materials(synthetic rubber, cement), with a total of 9 types repair materials, were selected and examined. As a result, the test results showed that the smallest performance deterioration by the change in the mass was with the synthetic rubber(RG) type as opposed to the cement type system, showing that the synthetic rubber type had the strongest relative resistance to chemical exposure. Furthermore, it is necessary to investigate the material with high resistance to chemical substances and to examine the material which can increase resistance to sodium hydroxide and sodium chloride in cement system. These results can be used as a basic index for the selection of repair materials with the strongest resistance to chemical environment found in concrete structures. In addition, it is expected that the test results derived in this study can be used as reference data that can be reflected in the quality improvement of the maintenance material to be developed later.

The completion of the Human Genome Project that identified all 3 billion base pairs in the human genome can be seen as a step towards understanding the relay of information and intention within an organism, or in other words, the language of life. The faculty of human language, key to differentiating humans from other animate species, works for conveying information to others by mapping meaning to sound based on syntactic structures. This resemblance between life and language has not gone unnoticed; the literature on RNA transcription and translation research regularly uses linguistic metaphors and the biolinguistic perspective of language has also been studied. By examining the biological characteristics of language and the linguistic characteristics of life, this study aims to identify key mechanisms shared between the two systems in order to promote a stronger connection between them. It furthers this goal by pointing out two general messages to which these mechanisms aim, productivity and accuracy, and discovers what lesson these messages give to a human society geared for sustainability.

Objective : This study was designed to find the correlation between Sasang Constitution and heart rate variability(HRV). Method : There were 665 subjects (280 men and 385 women), between 39 and 72 years old. in a rural community. Sasang Constitution was diagnosed by a Sasang constitutional specialist using PSSC (Phonetic System for Sasang Constitution), face and tongue photo and checkup-list. A structured-questionnaire was used to assess the general characteristics. HRV was recorded using SA-2000 (medi-core). HRV was assessed by time domain and by frequency domain analysis. Metabolic syndrome was defined on the basis of clustering of risk factors, when three or more of the following cardiovascular risk factors were included : blood pressure, fasting blood sugar, triglyceride HDL-cholesterol, and abdominal obesity (waist). Because of the skewness of the data, logarithmic transformation was performed on the absolute units of the spectral components of HRV, and the resulting logarithmic values and normalized units were compared between the groups by a logistic regression. The 95% confidence interval (CI) of the odds ratio was used and calculated from the data laid out for a cross sectional study. Results : 1. Odds ratios of Taeeumin and Soeumin in female adults below 60 years old were significantly lower than that of Soyangin in LF norm and LF/HF ratio. Odds ratios of Taeeumin and Soeumin in female adults below 60 years old were significantly higher than that of Soyangin in HF norm. 2. There was no significant correlation between HRV and Sasang Constitution in female adults from 60 years old and over. 3. There was no significant correlation between HRV and Sasang Constitution in male adults. Conclusion : There is a statistically significant correlation between the HRV and Sasang Constitution. There is a tendency of increase in the sympathetic activity in Soyangin. There is a tendency of decrease in the parasympathetic activity in Taeeumin and Soeumin.

최근들어 에너지 고갈로 인해 에너지 저장 및 대체 에너지에 대한 관심이 점차 높아 지고 있다. 이로 인해 상변화 물질을 이용한 에너지 저장 및 이동에 대한 연구가 활발히 진행 되고 있다. 본 연구에서는 SPG막(Shirasu porous glass membrane)을 통한 막유화법을 이용하여 상변화 물질인 파라핀계 루비덤$^{(R)}$ (RT-21과 RT-24)을 분산상으로 하여 단분산성 마이크로 입자를 제조하고, 외부를 실리카로 코팅하여 열정 안정성을 향상시키고 열적 특성을 조사하였다. 단분산성 루비덤$^{(R)}$ 입자의 제조를 위해 분산상 압력, 유화제 농도, 루비덤$^{(R)}$과 실리카의 비율을 변수로 하여 평균 입자 크기 $7-8{\mu}m$를 얻었다. Differential scanning calorimetry (DSC)와 Thermogravimetry analysis (TGA)를 이용하여 열적 안정성과 잠열 등의 열적 특성을 조사하였고, Particle size analyzer (PSA), Scanning electron microscopy(SEM), optical microscopy를 이용하여 입자 분포와 캡슐화 유무를 확인하였다. 또한, Fourier transform infrared spectroscopy (FT-IR)를 통하여 정성분석을 시행하였다. 결과적으로, 막유화법을 이용하여 얻은 실리카 코팅된 단분산성 루비덤$^{(R)}$ 입자는 향상된 열적 안정성을 보였으며, 순수한 루비덤$^{(R)}$의 80% 이상의 잠열을 유지하는 것을 보여 기존의 상변화 물질의 상안정성을 보완하여 열저장성 기능성 벽지와 건축물, 인테리어 제품에 사용 가능함을 알 수 있었다. Recently, the importance of energy saving and alternative energy is significantly increasing due to energy depletion and the phase change material (PCM) research for saving energy is also actively investigating. In this research, the membrane emulsification using SPG membrane was used to make various microencapsulated phase change material (MPCM) particles which were comprised of $Rubitherms^{(R)}$ (RT-21 and RT-24) core and silica coating. We investigated the pressure of the dispersion phase, the concentration of surfactant, and the ratio of $Rubitherm^{(R)}$ and silica to prepare various MPCM particles. The DSC and TGA were used to examine the heat stability and latent heat properties. Also, PSA, SEM, and optical microscopy were used to confirm the size of $Rubitherm^{(R)}$ particles and the thickness of silica shell. The average of particle size was $7-8{\mu}m$. And, FT-IR was also used to enforce the qualitative analysis. Finally, the MPCM particles obtained from membrane emulsification showed monodispersed size distribution and the heat stability and latent heat were kept up to 80% compared to pure $Rubitherm^{(R)}$. So, it can be effectively used for wallpaper, buildings and interior products for energy saving as PCMs.

온도에 따른 암모니아 용액에 의한 CO₂ 포집 반응의 변화 양상

김수연,최예슬,김동수,Kim, Soo-Yeon,Choi, Ye-Seul,Kim, Dong-Su 한국물환경학회 2011 한국물환경학회지 Vol.27 No.6

The features of the capture reaction of $CO_2$ by ammonia solution have been investigated along with the effect of temperature on the reaction based upon computer program-utilizing calculation and thermodynamic estimation. The stable region of $CO{_3}^{2-}$ was observed to increase with temperature and the change of the stable region of $CO{_3}^{2-}$ with temperature was greater than the temperature variation of the stable region of other carbonate species. The distribution diagram for $NH_4{^+}-NH_3$ system was constructed and the rise of temperature resulted in the decrease of the stability of $NH_4{^+}$ ion, which was thought to be due to the endothermic nature of its acidic dissociation. Considering the introduction of $Ca^{2+}$ ion in the carbon capture reaction by $NH_4{^+}$, the temperature was observed to be important in the determination of the order of reaction between carbonate ion and these cations. The removal process of $CO_2$ gas by ammonia solution was presumed to occur in open system and the temperature variations of the concentration of carbonate system species along with their total concentration were calculated for the proper control and design of the real process.
