기후변화와 관련한 한반도 배경대기의 에어러솔에 대한 특성 연구는 관측된 입자 수농도와 대기 복사 관측 자료를 바탕으로 에어러솔의 물리적, 화학적 및 광학적 특성에 대하여 분석하였다. 에어러솔의 물리적 특성 연구는 2001년부터 2003년까지 제주도 고산관측소에 설치된 광학입자계수기(Optical Particle Counter, OPC)로 $0.3{\sim}25{\mu}m$직경의 에어러솔을 8개 구간으로 나누어 관측하여 분석하였다. 그 결과 황사의 발생률이 높은 봄철에 조대 입자($2.2{\mu}m$이상)의 수농도가 다른 계절보다 높게 나타났다. 기상요소 (상대습도, 풍속, 풍향, 시정 등)와 입자 수농도의 상관관계 분석에 의하면 $0.3{\sim}0.5{\mu}m$ 크기 구간에서는 상관성이 없는 것으로 나타났으며 $0.5{\sim}2.23{\mu}m$ 구간에서는 에어러솔 수농도와 상대습도가 서로 양의 상관관계를 가지는 것으로 나타났다. 풍속과의 상관성에서 작은 입자들은 풍속이 강해질수록 감소하는 패턴으로 분석되었으며 겨울철에는 조대입자 수농도가 높은 풍속에 증가하는 것으로 나타났다. 그리고 시정거리는 $0.5{\sim}1{\mu}m$ 크기 정도의 에어러솔 수 농도와 밀접한 관련이 있는 것으로 나타났으며 에어러솔 수 농도가 증가할수록 시정거리는 감소하는 경향을 보였다. With the aim to develop the monitoring technology on background atmosphere and climate change over Korean Peninsula, observations and studies on chemical, physical and optical properties of the atmospheric aerosols are made. Aerosol number concentration are measured with Optical Particle Counter from 2001 to 2003 at Gosan for 8 size intervals from 0.3 to $25{\mu}m$ diameter range. For the seasonal variation, the number concentration of coarse particles in spring at Gosan was higher than other seasons due to the influence of sand storm in spring. There is no significant correlations between fine particles ($0.3{\sim}0.5{\mu}m$) and meteorological parameters, such as relative humidity, wind speed and visual range, while the correlation between the number concentration of small particles ($0.5{\sim}2.23{\mu}m$) and relative humidity showed a positive value. This trend was inversed for the case of wind speed: aerosol number concentration showed a small decreasing tendency with increasing wind speed for small particles but the high wind speed in winter season increased coarse particle concentration. Finally, Particles most efficient in light extinction were found to be at the size of about $0.5{\sim}1{\mu}m$.

소포체는 세포막의 합성뿐만 아니라 세포막에 존재하거나 세포외로 분비되어져야 할 단백질을 합성하는 세포내 소기관이다. 소포체에서 단백질이 합성되어질 경우 이황화결합이 형성되고 glycosylation 등의 수식이 일어나며, 이와 동시에 folding과 assembly과정을 거쳐 삼차원적 구조로 성숙이 되는데 이 과정은 folding enzyme과 molecular chaperone의 도움을 받아 이루어진다. 소포체 내에 존재하는 molecular chaperone 중 가장 잘 알려진 것으로 BiP이 있다. BiP의 기능은 N-terminus의 ATPase domain에 의해 조절되고 ATPase domain은 이것과 선택적으로 결합하는 조절인자에 의해 ATPase의 활성이 영향을 받는다. BiP의 핵산치환조절인자로서 발견된 BAP은 ATPase domain에 결합된 ADP를 ATP로 치환하는 것으로 기능이 알려져 있다. 이 BAP의 핵산치환기능이 BiP의 샤페론 작용에 어떤 영향을 미치는지를 in vitro에서 항체 heavy chain을 이용하여 알아보았다. BAP은 ATP보다 ADP가 결합되어 있는 BiP과 더 잘 결합을 하며, in vitro에서 BiP과 결합하고 있는 unfolded 단백질을 BAP은 BiP으로부터 해리하였다. 또한 소포체내에 존재하는 Hsp70 homologue chaperone인 BiP과 Grp170에 대한 BAP의 결합특이성을 anti-Grp170과 anti-BAP 항체로 co-immunoprecipitation을 하여 확인한 결과 BAP은 Grp170과 결합을 하지 않았다. 따라서 BAP은 ER내에 존재하는 동일한 family group에 속하는 Grp170과 BiP에 대하여 BiP에만 특이성을 갖는 것으로 나타났다. Molecular chaperones and folding enzymes in the endoplasmic reticulum (ER) associate with the newly synthesized proteins to prevent their aggregation and help them fold and assemble correctly. Chaperone function of BiP, which is a Hsp70 homologue in ER, is controlled by the N-terminal ATPase domain. The ATPase activity of the ATPase domain is affected by regulatory factors. BAP was identified as a nucleotide exchange factor of BiP (Grp78), which exchanges ADP with ATP in the ATPase domain of BiP This study presents whether BAP can influence folding of a protein, immunoglobulin heavy chain that is bound to BiP tightly. We first examined which nucleotide of ADP and ATP affects on BAP binding to BiP The data showed that endogenous BAP of HEK293 cells prefers ADP for binding to BiP in vitro, suggesting that BAP first releases ADP from the ATPase domain in order to exchange with ATP. Immunoglobulin heavy chain, an unfolded protein substrate, was released from BiP in the presence of BAP but not in the presence of ERdj3, which is another regulatory factor for BiP accelerating the rate of ATP hydrolysis of BiP The ADP-releasing function of BAP was, therefore, believed to be responsible for immunoglobulin heavy chain release from BiP. Grp170, another Hsp70 homologue in ER, did not co-precipited with BAP from $[^{35}S]$-metabolic labeled HEK293 lysate containing both overexpressed Grp170 and BAP. These data suggested that BAP has no specificity to Grp170 although the ATPase domains of Grp170 and BiP are homologous each other.

This study is to compare and analyze ‘the Korean energy saving design standard in building’ with ‘the passivehouse standard of PHI’ in Germany in using of energy efficient factors which have an effect on reducing energy demand in building. We used following architectural design method for energy efficiency : direction, south oriented window-wall ratio, insulation, glazing, frame, heat recovery, external blind, airtightness, thermal mass, ect. We set a base model and analyzed annual energy demand, heating&cooling demand through energy-simulation according to each standard above by energy efficient elements. Consequently, ‘the passivehouse standard of PHI’ is more effective on reducing energy use than ‘the Korean energy saving design standard in building’. Also, this study found energy efficiency rate for heating demand by elements and it is as in the following : Window(37.92%) > Heat recovery(27.87%) > Insulation(25.23%) > Airtightness(5.49%) > Internal/External Insulation(4.42%) > Thermal mass(3.99%) > South oriented window-wall ratio(0.29%) > External blind(0%). And we found that the external blind(56.2%) takes a key role in reducing cooling demand. Through this study, we discovered energy reducing rate by energy efficiency factors in building and with this result, we are expecting to make energy efficiency design standard for the improvement of the high energy-use detached house.

This study aimed to develop nail art designs inspired by the colors and patterns of fish scales. Various images of fish were collected, and the colors, patterns, and textures of their scales were analyzed. Using deep learning-based image generator, designs replicating the colors and patterns of fish scales were created. Based on these designs, five nail art works were produced. The colors and patterns of fish scales are suitable for creative nail art designs, and designs inspired by fish scales demonstrate excellent visual effects due to the appropriate application of principles of form and expression techniques. Moreover, nail art designs inspired by fish scales can enhance the artistry and distinctiveness of nail art. This research highlights the potential of using fish scale colors and patterns in nail art design and represents a novel approach to using deep learning-based image generators as creative tools in nail art design. However, the nail art works produced in this study were limited and reliant on subjective evaluations. Future research should apply diverse evaluation methods to measure the quality and satisfaction of nail art designs and expand the study to include nail art designs using other natural materials besides fish scales.

In this study, we compared daily (diet, exercise, smoking, drinking et al.) and hair care habits and the condition of scalp and hair focusing Korean and American high school girls whose social background and culture were different from each other. Through this study we intended to provide practical and useful information on scalp and hair care for teenagers. Data were collected through a questionnaire survey of 118 Korean and 98 white American high school girls. We carried out t-test, frequency analysis, and one-way ANOVA for the data analysis. Korean high school girls showed more irregular daily habits than American girls and Korean girls also had less vegetables, fruits, and water in their diet than American girls. Both groups did not eat enough fish like anchovy, sea weed but they had much of instant food instead of real food. Korean high school girls exhibited more oily scalps and American girls had more normal scalps. Korean girls showed more damaged hair due to hot permanent wave, so their hair showed more hair break off and spilt ends. Korean high school girls worried about damaged hair, oily scalp, hair losss and no shine hair for their hair care. On the other hand American girls more worried about dandruff and hair break trouble due to thin hair. American high school girls showed more tied hair than Korean girls and they dried well their hair after shampooing. American high school girls used less hot curlers and hair dryer but they consumed more hair wax and hair spray goods than Korean girls did. Futhermore American high school girls used more hair treatment goods to have their hair shiny and glossy. However, American high school girls paid more attention to the instruction and caution note on the hair treatment goods after purchasing.
