Purpose: Many university students are under a lot of job-seeking stress because the employment rate is low. This study sought to determine the relationship between job-seeking stress, self esteem, self efficacy and appearance management behavior amongst university students focusing on nursing. Methods: This descriptive correlational study evaluated the relationships between job-seeking stress, self esteem, self efficacy and appearance management behavior of 340 university students was conducted between September 1 and October 5, 2015. Results: The correlational analysis between job-seeking stress, self esteem, self efficacy and appearance management behavior revealed a negative correlation between job-seeking stress, self esteem and self efficacy and a positive correlation between job-seeking stress and appearance management behavior. In addition, age also correlated with self esteem, self efficacy and appearance management behavior. Conclusion: Stress correlated with self esteem and self efficacy and appearance management behavior. Therefore job-seeking stress may be reduced through not only self esteem and self efficacy enhancement programs but also management according to age.

The purpose of this study was to investigate the changes in the composition of pork belly, which is known to be nutritious and the most preferred Korean food, before and after cooking. In the experiment, weight change, moisture content and crude fat content of pork belly were examined before and after cooking. The mean weight of pork belly before heat treatment was 51.67g and the mean weight after treatment was 37.6g. The average value of the weight after treatment was 14.07 g. After baking the pork belly, it was confirmed that the weight of about 14g decreased on average. Change in moisture content before and after cooking was in the range of 6% to 20%, and the lowest moisture content was 3.68g in sample 4, which showed a moisture content of 6% and the water change of sample 3 was 11.13g, which showed a 20% decrease in water content. The average fat weight of the pork belly before cooking was 2.0586g, the average crude fat percentage (%) was 39.44%, the average fat weight after cooking was 1.5914g, the average crude fat percentage (%) was 31.91%. Because of the nature of the experiment, the samples before and after cooking were not the same and could not be compared exactly one to one, but it was confirmed that the amount of fat content before and after heating was remarkably reduced. The average crude fat content before cooking of pork belly was 39.44% and it was decreased to 31.91% after cooking. The current data implied that cooking process greatly cut off amount of fat intake of consumption.

Although rodents have previously been used in ecotoxicological studies, they are expensive, time-consuming, and are limited by strict legal restrictions. The present study used a zebrafish (Danio rerio) model and generated data that was useful for extrapolating toxicant effects in this system to that of humans. Here we treated embryos of the naive-type as well as a transiently transfected zebrafish liver cell line carrying a plasmid (phAhREEGFP), for comparing toxicity levels with the well-known aryl hydrocarbon receptor (AhR)-binding toxicants: 3,3’,4,4’,5-pentachlorobiphenyl (PCB126), 2,3,7,8-tetrachlorodibenzo- p-dioxin, and 3-methylcholanthrene. These toxicants induced a concentration-dependent increase in morphological disruption, indicating toxicity at early life-stages. The transient transgenic zebrafish liver cell line was sensitive enough to these toxicants to express the CYP1A1 regulated enhanced green fluorescent protein. The findings of this study demonstrated that the zebrafish in vivo model might allow for extremely rapid and reproducible toxicological profiling of early life-stage embryo development. We have also shown that the transient transgenic zebrafish liver cell line can be used for research on AhR mechanism studies.
Highly Angle-tolerant Spectral Filter Based on an Etalon Resonator Incorporating a High Index Cavity
Tae-Hui Noh,윤여택,이상신,Duk-Yong Choi,Seung-Chan Lim 한국광학회 2012 Current Optics and Photonics Vol.16 No.3
A high angular tolerance spectral filter was realized incorporating an etalon, which consists of a TiO2cavity sandwiched between a pair of Ag/Ge mirrors. The effective angle was substantially extended thanks to the cavity’s high refractive index. The device was created by embedding a 313-nm thick TiO2 film in 16-nm thick Ag/Ge films through sputtering, with the Ge layer alleviating the roughness and adhesion of the Ag layer. For normal incidence, the observed center wavelength and transmission were ~900 nm and ~60%, respectively; throughout the range of 50°, the relative wavelength shift and transmission variation amounted to only ~0.06 and ~4%, respectively.

‘캠벨얼리’ 아조변이체의 배수성을 flow cytometry(FCM)를 이용하여 검정하였다. 2배체 포도인 ‘캠벨얼리’와 4배체 포도인 ‘거봉’과는 달리 ‘캠벨얼리’에서 발생한 아조변이 3계통의 경우, 잎에서 2배체와 4배체 peak가 동시에 나타났다. 또한 ‘캠벨얼리’ 포도의 과육과 과피의 배수성은 2배체 peak를 보인 반면, ‘캠벨얼리’ 아조변이체는 과피의 배수성은 2배체로, 과육의 배수성은 4배체로 검정되었다. 정확한 염색체 숫자를 알아보기 위해 ‘캠벨얼리’ 유래 아조변이체, ‘캠벨어리’, ‘거봉’ 포도의 근단 조직 염색체 숫자를 현미경 검경하였다. ‘캠벨얼리’와 ‘거봉’은 각각 38, 76개의 염색체로 나타난 반면 아조변이체는 2x=38, 4x=76개의 염색체가 혼재한 것으로 나타났다. ‘캠벨얼리’ 아조변이체의 키메라 형태를 알아보기 위하여 신초 정단 분열조직을 현미경 관찰하였다. 대조구로 이용된 2배체 ‘캠벨얼리’와 4배체 ‘거봉’ 포도는 2개의 tunica 층이 corpus층을 덮고 있었으며, 반면에 아조변이체의 경우 첫번째 tunica 층이 독특하게 분할되어 있었다. ‘거봉’ 포도의 정단분열 조직의 세포 크기는 대체로 ‘캠벨얼리’ 포도보다 더 컸다. 아조변이체의 L-2, L-3 층을 이루고 있는 세포 크기는 4배체인 ‘거봉’ 세포와 유사하였으며 가장 바깥쪽 L-1층을 이루고 있는 세포의 크기는 ‘캠벨얼리’ 포도와 유사한 크기였다. 따라서 본 시험의 결과 ‘캠벨얼리’ 포도 품종에서 발생한 아조변이체들은 2-4-4형 키메라의 가능성이 높은 것으로 판단되었다. Flow cytometry (FCM) was used to measure the ploidy level of three different sports from ‘Campbell Early’ (Vitis labruscana) grape. Results of the study showed different ploidy levels. FCM analysis for ‘Campbell Early’ grape which contains 2C DNA diploid cells showed single peak around 35-40 while ‘Kyoho’ grape with 4C DNA tetraploid cells had a different level of 70-80. However, analysis of the sports displayed a histogram with 2 peaks containing both 2C and 4C nuclei. There was no difference in histograms of 2C DNA flesh and pericarp; on the other hand, 4C DNA flesh type of sports had a different histogram from that of the 2C DNA pericarp. Chromosome numbers of diploid (‘Campbell Early’), tetraploid (‘Kyoho’), and three sports were counted under the microscope. ‘Campbell Early’ and ‘Kyoho’ have 38 and 76 chromosomes, respectively. Three different sports are mixoploids with mixtures of diploid and tetraploid cells. Microscopic observations of shoot apical meristems in sports from ‘Campbell Early’ grape were carried out to determine the type of plant chimera. ‘Campbell Early’ grape (diploid) and ‘Kyoho’ grape (tetraploid) showed that both had 2 tunica layers covering corpus cells, while the three different sports had tunica layers showing mostly oblique division. Most cells from ‘Kyoho’ grape were larger than ‘Campbell Early’ grape. Cells from L-2 and L-3 layers of the three sports were similar to ‘Kyoho’ grape in size, although all cells in L-1 surface layer were uniform in size like ‘Campbell Early’ grape. Results of FCM analysis indicated that both normal and polyploid cells could be intermixed in sports and could become mixoploidy consisting of diploid and tetraploid. All sports used in the tests were periclinal chimera plants with two distinct L-1 and L-2 cell layers. The result of this study suggests that all three sports which originated from ‘Campbell Early’ grape might be 2-4-4 type chimera formation.
