A FET type micro CO_(2) sensor based on a Severinghaus type arrangement has been prepared and its response characteristics were examined. The sensor was fabricated by formation of hydrogel layer containing bicarbonate/chloride ions on the PH-ISFET and the Ag/AgCl reference electrode prepared by the thermal evaporation and chemical chloridation methods. And then gas-permeable membrane was dip-coated on the hydrogel layer of the sensor. Gas-permeable membranes were fabricated with silicon rubber and polyurethane dissolved in toluene and THF, respectively. The CO_(2) sensor with the silicon rubber membrane showed better sensitivity and lower detection limit than the CO_(2) sensor with the polyurethane membrane for dissolved CO_(2). The sensor with silicon rubber membrane at optimal conditions showed a good response: linear range of 1.60X10^(-4) ~ 4.40X10^(-2) M CO_(2), sensitivity of 57.30 mV/decade, and detection limit of 7.50x10^(-4) M.

한국 패션모델의 '몸 규제' 경험과 젠더차이

정은아,손승영 동덕여자대학교 한국여성연구소 2009 젠더연구 Vol.- No.14

This paper aims to reveal the social structure which controls and forces women to have idealized body by studying fashion models that are under certain pressure to keep their bodies desirable. We tried to find out the gender differences in idealizing the perfect image as a fashion model and going though physical treatments such as diets, cosmetic treatments and surgeries, massages and workout programs. We used questionnaire survey method which was proceeded between December 2008 and June 2009. As sample of Korean fashion models, 114 females and 26 males who had worked for more than six months were chosen. The major findings are as follows. The socially accepted image of 'ideal body' influences female models to adopt the concept and practice hard to achieve their goal. On the other hand, male models seem to be more attractive when they look healthy. That is the reason why male models take exercise more seriously than diet and experience less 'physical pain' compared to female models. It shows that each gender's body has different expectation based on patriarchal culture of the society. Women can be considered beautiful enough when they sacrifice their health. Male models understand the effort to keep their bodies attractive as a part of their work, although female models do as a part of their lives. Having better appearances is not only their work, but also the only way they can survive in the patriarchal society. In addition, more male models are in independent positions compared to female models in many important aspects such as payment, professionalism and relationships with designers.

손은미 ( Eun Mi Sohn ),박운정 ( Oun Joung Park ),오미자 ( Mi Ja Oh ) 대한관광경영학회 2015 觀光硏究 Vol.30 No.5

본 연구의 목적은 인터넷환경에서의 라이프스타일에 따른 온라인 관광정보원천 이용과 만족도, 여행관여도의 영향관계를 살펴 본 후 온라인 마케팅적 시사점을 도출하는데 있다. 이러한 본 연구의 목적을 달성하기 위해 대학생들을 대상으로 총 226부의 설문지를 획득하여 구조방정식 모델을 분석하였으며 그 결과는 다음과 같다. 첫째, I-VALS는 소비자검색사이트 이용정도에 유의한 영향을 미치는 것으로 나왔다. 둘째, 소비자검색사이트 이용정도는 관광정보 만족도에 유의한 영향을 미친다는 분석 결과가 나왔다. 좀 더 세부적으로, ‘쇼핑 및 정보지향형’과 ‘개성 및 새로움 지향형’의 라이프 스타일은 소비자검색사이트 이용정도에 유의한 영향을 미친다는 결과가 나왔다. 셋째, I-VALS가 소비자검색사이트 이용정도에 미치는 영향 정도는 여행관여도에 따라 다르다는 것을 알 수 있었다. 특히 ‘개성 및 새로움지향형’과 ‘인간관계지향형’의 라이프 스타일의 그룹에서는 소비자검색사이트 이용정도가 여행 관여도에 따라 유의하게 다르게 나타나는 것을 알 수 있었다. The aim of this study is to examine the structural relationships of internet life-style, tourism information sources and satisfaction to figure out suitable online marking implications. For this purpose, 226 questionnaire survey sheets were collected from university students which were analyzed using SPSS 18.0 and AMOS 21.0 statistic program. The results are as follows. Firstly, hypothesis 1 ‘I-VALS would have significant impact on consumer search site use’ was partially adopted. Hypothesis 2 ‘level of use of consumer search site would have significant impact on tourism information satisfaction`` was adopted. Specifically, ‘shopping/ information-oriented type’ and ``personality/novelty- oriented type’ had significant impact on the level of use of consumer search site. Finally, hypothesis 3 ‘I-VALS would have different impact on the level of use of consumer search site by the tourism involvement level`` was partially adopted. Specifically, tourism involvement had moderating effect on ``personality/novelty-oriented type’ and ‘human relation-oriented type’ had moderating effect on the level of use of consumer search site.

패션모델의 노동경험 : ‘몸 프로젝트’ 및 ‘프로정신’을 내세운 요구와 수용

정은아(Joung Eun Aa),손승영(Sohn Seong Young) 한국여성학회 2010 한국여성학 Vol.26 No.3

몸이 정체성의 표현으로 읽혀지는 현대 한국사회에서, 여성들은 이상화된 미의 기준에 도달하도록 끊임없이 사회화되고 있다. 특히 패션모델과 같이 직접적으로 자원화 되는 몸을 가진 여성들에게 몸 가꾸기 노력은 더욱 가시화되어 나타난다. 이 연구에서는 패션모델의 몸만들기가 직업적 특성과 연계되어 있는 점에 주목하여, 여성들의 몸에 대한 에이전시의 규제뿐만 아니라 모델들의 자발적 노력과 수용 과정에서 작동하는 메커니즘에 대해서도 밝혀보고자 하였다. 2009년 5월부터 7월까지 17명의 남녀 모델들을 면접한 결과, 첫째, 모델 입문시기와 계기에 있어서 뚜렷한 젠더차이가 나타났다. 둘째, 여성 모델들은 지속적인 자기검열과 비교 및 정보 수집을 통해 다이어트, 성형 등과 같은 몸 관리방식을 실천하고 있다. 특히 에이전시나 패션디자이너의 권유에 의해 체계적인 ‘몸 프로젝트’에 가담하게 된다. 셋째, 고용주들은 ‘프로정신’을 강조하는 방식으로 패션모델들의 몸을 통제하거나 명령체계를 형성하고 있으며, 여성 모델들 또한 프로정신을 내세워 스스로의 욕망과 열정을 관리하므로 부당한 대우를 받더라도 저항하기 힘든 상황에 놓여있다. This paper aims to reveal the social structure which controls and forces women to have idealized body by studying fashion models who are under certain pressure to keep their bodies desirable. Because women's bodies are easily objectified and evaluated by gender biases in the patriarchal culture, more women than men are affected by other people who constantly encourage them to be fashion models. This study attempts to find out the underlying mechanism of how women's body project is related to their work characteristics and how female fashion models are willingly regulated by their agencies. Interviewing 17 female and male models between May and July 2009, we could find out the following aspects. First, there were distinguished gender differences in entering time and reasons to work as fashion models. While most of female models started their work as a teenager by persuasion of other people, males joined to work as fashion models in the age of 20s by their own choice. Second, female fashion models practice various methods of making their own body by self-examination and comparison with other models. Especially they participate in 'body project' by demands of agencies or fashion designers. Third, since the female fashion models accepted the 'pro(fessional) spirit' which the employers had emphasized, it was difficult for the fashion models to resist against the orders even when they experience unfair treatments.

The detection of C-reactive protein(CRP) using self-assembled monolayer(SAM) was investigated by a portable surface plasmon resonance(SPR) sensor system. The CRP is a biomarker for the possible cardiovascular disease. The SAM was formed on gold(Au) surface to anchor the monoclonal antibody of CRP(anti-CRP) for detection of CRP. Sequence injection of the anti-CRP and bovine serum albumin(BSA) into the sensor system has been carried out immobilize the antibody and to prevent non-specific binding. The portable SPR system has two flow channels: one for the sample measurements and the other for the reference. The output SPR signal was increased with the injection of the anti-CRP, BSA and CRP due to binding of the proteins on the sensor chip. The valid output SPR signal was linearly related to the critical range of the CRP concentration. The experimental results showed the feasibility of the portable SPR system with newly developed SAM to diagnose a risk of the future cardiovascular events.

카드뮴 및 Adriamycin 저항성 CHO 세포의 Telomeric Band 의 변화

정해원,정경인,손은희 한국유전학회 1997 Genes & Genomics Vol.19 No.3

To investigate the properties and functions of telomere in cells resistant to cadmium and adriamycin, changes of telomeric band number were studied using fluorescence in situ hybridization (FISH) technique. To determine the amplification of telomeric signal, we counted total number of telomeric bands, number of marker chromosomes and number of double minutes (DMs) in cadmium resistant and adriamycin resistant cell groups. Cell lines exposed to cadmium showed higher ITB scores than controls. Cell line with longest exposure to cadmium had the highest ITBs. Adriamycin resistant cell lines showed lower ITB scores than controls. Number of marker chromosomes in cadmium resistant cell lines was similar to that in control cells whereas that in adriamycin resistant cell lines was decreased. Total number of DMs with presence of telomere signal was increased in cadmium resistant CHO cells, whereas no increase was found in adriamycin resistant cells. Our results suggest that there might be different mechanisms in the acquisition of resistance to different agents.

본 연구는 히터팬 처리에 의한 시설환경 개선 및 참외의 품질 및 수량성을 검정코자 수행하였다. 히터팬 처리에 따른 2017년 1월 1일부터 31일간 터널내부의 일평균 온도는 무처리구의 17.8℃에 비하여 히터팬 처리구에서는 18.7℃로 히터팬 처리구에서 0.9℃ 더 높았다. 작물이 자라고 있는 지상 20㎝ 부위의 풍속은 무처리구의 0.05m·s<SUP>-1</SUP>에 비해 히터팬 처리구에서 0.24m·s<SUP>-1</SUP>로 4.8배 높았고 온도는 무처리구의 35.3℃에 비해 히터팬 처리구에서는 40.9℃로 히터팬 처리구에서 5.6℃ 더 높았으나 습도는 무처리구의 39.1%에 비해 8.1%P 더 낮았다. 정식 51일후 개화율 조사에서 무처리구의 91%에 비하여 히터팬 처리구에서는 96%로 5%P 더 높았고, 첫 수확소요일수도 무처리구의 86일에 비해 4일 단축되었다. 과중은 무처리구의 339.7g에 비하여 히터팬 처리구에서 15.1g 더 무거웠고 상품과율도 90.4%에 비하여 3.4%P 더 많았으며 10a당 상품수량도 142.9㎏에 비하여 38% 더 증가하여 95% 수준에서 통계적 유의성이 인정되었다. 이상의 결과를 종합 하면 히터팬 처리로 시설내 온도상승은 물론 공기의 유동이 활발하여 작물생육에 유리하고 수확시기가 단축되고 품질이 향상되고 수량이 증가하는 것을 알 수 있었다. The purpose of this study was to investigate the changes of environmental conditions and the quality and yield of melon fruit by heat fan operation in greenhouses at winter season. The average daily temperature inside the tunnels during January 1 to 31, 2017 was 0.9℃ higher than that of the control 17.8℃. The air flow rate of heater fan treatment was 4.8 times higher than the control (untreated 0.05 m·s<SUP>-1</SUP>) at 20㎝ above the ground where the korean melon grew. The temperature of the heater pan was 5.6℃ higher than that of the untreated at 35.3℃ and the relative humidity was 8.1% lower than that of the untreated at 39.1%. The flowering rate of the heater fan treatment was 96%, 5% higher than the control. The number of first harvest days of heater fan treatment was shortened by 4 days than that of untreated treatment. Fruit quality and marketable fruit yield increased by 3.4% and 38% compared to untreated respectively, the heater fan treatment increased the temperature inside the greenhouse and air flow rete, which were beneficial for growing the korean melon in greenhouses at winter season.

Objective The purpose of this study is to identify the demographic variables that are affecting performances on the Logical Memory (LM) subtest included in the Korean version of the Wechsler Memory Scale (WMS)-IV and to provide normative data on the LM subtest for the middle-age and elderly Korean people. Methods The participants were 435 non-demented adults aging from 50 to 90 and with the educational level ranging from 0 to 21 years. Results Age and education were found to be significantly associated with performance on the LM subtest, while gender effect was not statistically significant. Therefore, we stratified the norm blocks by age and education. Age was divided into three groups: 50–59, 60–74, and 75–90 years. Education was stratified into three groups: 0–8 years, 9–12 years, and 13 years or more. Conclusion The normative data provided in the current study are expected to be useful in clinical and research settings to detect or define subtle changes in episodic memory in Korean adults and elderly, and can also be used for cross-cultural comparison of verbal episodic memory performance among elderly populations using different languages.

Recombinant interferon alpha-2a is an active formula for the treatment of various cancer cells like malignant melanoma and a variety of virus infection diseases like acute or chronic hepatitis. The bioassay system based on the measurement of virus inhibitory activity by interferon has been used for interferon analysis with low repeatability. Here, we developed the HPLC assay to measure reproducibly interferon alpha-2a protein content which is replaceable to the reported bioassay. This method separated interferon alpha-2a from its oxidized forms and human serum albumin used as excipients. The regression coefficient using interferon alpha-2a EP CRS is more than 0.9 in the range from 5 ${\mu}g/ml$ to 200 ${\mu}g/ml$. The recovery result in the range from 15 ${\mu}g/ml$ to 60 ${\mu}g/ml$ is $97{\sim}104%$ and the precision is $0.2{\sim}1.7%$. The interferon alpha contents of 5 products are about 30 ${\mu}g/ml$.
