Recently, there has been a shift to salon styles which are immediately applicable to customers as WORLDSKILLS asks for practical and commercial design. Under such circumstances, this study attempted to analyze projects which revealed such change among those designed focusing on the art of National Skills Competition. For this, data were primarily collected from the job descriptions provided by MEISTER NET and hairstyle projects on women in National Skills Competition. The scope of research was limited to year 2018 and year 2020, and the results found the followings: In 2020 National Skills Competition, practical salon styles which are readily applicable to the fields were more focused than those that require personal skills and creativity. Therefore, under the concept that such competition is an extension of industrial sites, it is required to prepare National Skills Competition by building the ability to reanalyze the conventional fancy and artistic value-oriented styles in practical design. It is anticipated that the study results would be available for those preparing for such competition.

This study developed haircut diagrams in consideration of the head shape and hair texture of Koreans, using the architecture of Antoni Gaudi, a visionary architect creating space in fantasy and a magician of formative art, as a motif. After emphasizing the structural characteristics of architecture through analysis and visualization of visualizing the images and features of Gaudi’s works, linear, geometrical and curved shapes were applied to haircut diagrams. First, the formative features of Antoni Gaudi’s architecture were investigated, and his diverse works were thoroughly analyzed. Specifically, considering the shapes the Korean head, a total of five different haircut diagrams were developed as follows: i) triangular diagram expressing vertical and slanted pagodas in a certain pattern, which can generate geometrical visual effects at the Sagrada FamFlia, ii) diagram expressing the parabolic roof, domes and columns inside the Catholic church, iii) diagram illustrating fan-shaped staircase and Doric-style columns at Park Guell, iv) diagram describing the curved and arc pedestrian path, v) diagram illustrating the sea wave-patterned curves at Casa Mila. Based on the above haircut diagrams, then, haircuts were completed. As a result, the study was able to create light hairstyles without texture cut based on the diagrams designed for the shape of Korean heads, making the volume-less Korean people’s hair voluminous. Furthermore, an easy liberal haircut was enabled, using repetitive patterns.

Bacillus licheniformis를 이용한 청국장 제조 시 키토산 첨가(0, 0.5 및 1%)가 청국장의 품질 특성에 미치는 영향을 조사하였다. 청국장 발효는 40℃에서 48시간 발효시켰다. 그 결과 pH는 모든 실험구에서 8.04~8.17범위로 유의성이 없었으나 총균수는 키토산 1% 첨가 청국장에서 유의적으로 낮았다. 키토산의 첨가량에 따라 L<SUP>*</SUP>값 및 b<SUP>*</SUP>값은 감소하였으나 a<SUP>*</SUP>값은 증가하는 경향을 보였다. 점질물 함량은 유의차가 없었으나 glucosamine, 지질, 총 유리아미노산 및 지방산 함량은 키토산 첨가량에 따라 증가하였다. 관능검사 결과 유의성은 없으나 키토산을 첨가함으로써 청국장의 쓴맛과 냄새를 감소하고 구수한 맛을 증가시켜 종합적 기호도를 향상시키는 효과가 있었다. Effect of chitosan addition (0, 0.5 and 1% of steamed soybeans) on quality of chungkukjang fermented by Bacillus licheniformis at 40℃ for 48 hr was investigated. Chitosan addition did not affect the pH and slime content of chungkukjang, irrespective of chitosan concentrations. The number of total microbes was slightly lower for chungkukjang added with 1% chitosan compared with those added with 0 and 0.5% chitosan. Color L<SUP>*</SUP> and b<SUP>*</SUP> values decreased while a<SUP>*</SUP> value increased with increasing chitosan concentration. The contents of glucosamine, lipid, total free amino acids, and fatty acids increased with increasing chitosan concentration. Chungkukjang added with 1% chitosan showed better overall acceptability compared with those added with 0 and 0.5% chitosan.

<P>Developments of high-performance cost-effective electrocatalyts that can replace Pt catalysts have been a central theme in polymer electrolyte membrane fuel cells (PEMFCs) and direct methanol fuel cells (DMFCs). In this direction, nitrogen-doped carbon nanostructures free of metallic components have attracted particular attention. Here we show that directing graphitic carbon nitride frameworks into mesoporous architecture can generate a highly promising metal-free electrocatalyst for an oxygen reduction reaction (ORR) in an acidic medium. The ordered mesoporous carbon nitride (OMCN) was synthesized with a nanocasting strategy using ordered mesoporous silica as a template. A variety of characterizations revealed that the OMCN is constructed with graphitic carbon nitride frameworks and ordered arrays of uniform mesopores. The OMCN showed significantly enhanced electrocatalytic activity for ORR compared to bulk carbon nitride and ordered mesoporous carbon in terms of the current density and onset potential. A high surface area and an increased density of catalytically active nitrogen groups in the OMCN appear to contribute concomitantly to the enhanced performance of the OMCN. Furthermore, the OMCN exhibited superior durability and methanol tolerance to a Pt/C catalyst, suggesting its widespread utilization as an electrocatalyst for PEMFCs and DMFCs.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/langd5/2012/langd5.2012.28.issue-1/la204130e/production/images/medium/la-2011-04130e_0005.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/la204130e'>ACS Electronic Supporting Info</A></P>

The goal of this study is to replace the current forward 2-piece propeller shaft of 8 ton large truck made of steel with 1-piece composite propeller shaft. A low cost Glass/Epoxy composite propeller shafts were successfully developed, which satisfy requirements such as the capacity of static torque transfer, fatigue strength and bending natural frequency. Devising secure joining method of a composite tube and metal yoke was the most critical issue in successful development of a high torque composite propeller shaft. In this study, joining method using thermal interference fit was adopted for composite to metal joint. Optimum conditions of heating temperature and interference level of thermal interference fit were determined from thermal stress analysis using 3D finite element method. Static torsion test, fatigue test, RPM and balance test were performed to verify the design.<br/>

The corrosion behavior of stainless steel 304 (SS 304), titanium, nickel and aluminium is studied by immersion and anodic polarization tests in non-aqueous electrolytes. Tetraethyl ammonium tetrafluoroborate is used as a supporting electrolyte in the three kinds of solvents. The immersion test shows that chemical corrosion rate in propylene carbonate-based electrolyte is lower than those in acetonitrile- or ${\gamma}$-butyrolactone-based electrolytes. Surface analyses do not reveal any corrosion product formed after the immersion test. In the anodic polarization tests, a higher concentration of supporting electrolyte gives a higher current density. In addition, a higher temperature increases the current density in the active region and reduces the potential range in the passive region. SS 304 shows the highest corrosion potential while Al shows the lowest corrosion potential and the highest current density in all studied conditions. Based on the conducted corrosion tests, the corrosion resistance of metal substrates in the organic solvents can be sorted in descending order as follows: SS 304 - Ti - Ni - Al.
