  • Pompholyx is a special vesicular type of hand and foot dermatitis. It is an acute, chronic or recurrent dermatosis of the fingers, palms and soles, characterized by a sudden onset of many deep-seated pruritic clear vesicles. We diagnosed a patient with pompholyx as damp heat and treated with wet dressing by gauze soaked in distilled solution of Gamihwangryunhaedok-tang(Jiaweihuanglianjiedu-tang). After treatment with wet dressing, we observed the improvement. Based on this study, it is considered that wet dressing with Gamihwangryunhaedok-tang(Jiaweihuanglianjiedu-tang) can be applied to the treatment of pompholyx.

  • Wet plating has been initiated and developed as a major surface finishing technology as of the long customized and highly productive process until now. As the external compression by virtue of the environmental preservation becomes stricter, there has been new move to adapt dry plating line instead of conventional wet plating one in domestic surface finishing industry. Dry plating, so-called, plasma surface technology has been developed in semiconducting industry and becomes a key technology to be useful as an alternative to wet plating in surface finishing industry. The historical progress of domestic surface finishing industry was outlined with the background on the adaptation of three dry plating processes-plasma spraying, plasma nitriding and ion plating. The present status of domestic industrial activity was covered on major alternative to wet plating.

  • In this study, cocoons from different silkworm strains and rearing seasons were collected and immersed in water at elevated temperatures to investigate the effect of a wet treatment on their morphology and crystallinity. Untreated cocoons exhibited different crystallinities depending on the silkworm strain and rearing season; however, no distinct changes in their morphological structure were observed. Furthermore, after wet treatment, the differences in the crystallinities of cocoons disappeared. In addition, wet treatment of degummed silk (i.e., fibroin) did not change its crystallinity. These results indicate that different crystallinities of the untreated cocoons collected from various silkworm strains and rearing seasons are due to the different characteristics of sericin in the cocoons.

  • An innovative concept for wet-transportation and stepwise installation of mono-bucket foundation for 15 MW offshore wind turbine is proposed. Case studies for two different mono-bucket and wrap-buoy dimensions are conducted and their hydrostatic and hydrodynamic performances are compared for both wet-towing and lowering operations. The intact stability and transient responses are analyzed in detail for various stages of lowering operation. Wave-induced motion statistics during wet tow in sea state 4 (highest operational window) are checked. The proposed concept is found to be feasible and can be an alternative cost-effective solution without using heavy-lift crane vessel in practice.

  • In emerging countries, traditional retail, such as wet markets, still accounts for a large proportion of retail sales. Traditional retail has poor infrastructure compared to modern retail, and is often associated with problems of waste, water, and environmental pollution. Therefore, traditional retail faces extreme difficulties in achieving sustainability. This study aimed to determine what value traditional retail contributes to sustainability. We generated and applied a conceptual framework of sustainability to explore this question. We used a single case study of a small-scale wet market in Vietnam. The results showed that wet markets have significant value for the development of sustainable retail, including economic, environmental, social, and community value. This study extends the literature by providing a comprehensive and accurate view about the value of traditional retail in contributing to sustainability. It suggests strategies for traditional retail in emerging countries to survive sustainably.

  • In this study, the wet surface heat transfer coefficients and friction factors of the heat exchanger with slit-wavy fin were measured. Four sample cores of two or three row with fins of 12 fpi or 16 fpi were tested. Tests were conducted in a closed loop wind tunnel, where the heat exchanger was mounted at 45 degree inclination angle. The wet surface heat transfer coefficient was reduced following the procedure given in ARI 420-81. During the course, new definitions of the $\varepsilon$-NTU applicable to enthalpy driving system were introduced. The wet surface heat transfer coefficients were approximately equal to the dry surface values. However, the friction factors were approximately 120% to 170% higher than those of the dry surface. Both the heat transfer coefficient and the friction factor of the wet surface increased as the relative humidity increased, fin pitch decreased, and the number of row decreased, although the difference was not large.

  • The production of fine wire through multi-pass wet wire drawing process would be impossible with no backtension at inlet of dies. Backtension is affected by many process parameters, such as dies reduction, coiling number of wire at capstan, machine constant, slip between wire and capstan, characteristic of lubricant and so on. Up to date, dies design and dies pass schedule of multi-pass wet wire drawing process have performed by trial and error of expert in the Industrial field without consideration of quantitative relation among process variables. Thus study investigates the multi-pass wet wire drawing process considering the relation among process variables, such as dies reduction, coiling number of wire at capstan, machine constant, slip between wire and capstan, etc. And analysis program which can analyze many important process values(drawing force, backtension force, slip rate, slip velocity rate, etc) for die design and dies pass schedule of multi-pass wet wire drawing process was developed.

  • In this paper, we investigated about wet cleaning effect as deep trench formation methods for Power chip devices. Deep trench structure was classified by two methods, PSU (Poly Stick Up) and Non-PSU structure. In this paper, we could remove residue defect during wet. cleaning after deep trench etch process for non-PSU structure device as to change wet cleaning process condition. V-SEM result showed void image at the trench bottom site due to residue defect and residue component was oxide by EDS analysis. In order to find the reason of happening residue defect, we experimented about various process conditions. So, defect source was that oxide film was re-deposited at trench bottom by changed to hydrophobic property at substrate during hard mask removal process. Therefore, in order to removal residue defect, we added in-situ SCI during hard mask removal process, and defect was removed perfectly. And WLR (Wafer Level Reliability) test result was no difference between normal and optimized process condition.

  • The effect of addition with maesil(Prunus mume) juice for extending the shelf-life of wet noodle was investigated by measuring quality changes such as total microbial count and pH. The Prunus mume juice showed antimicrobial activities against Salmonella enteritidis, Staphylococcus aureus, Bacillus cereus, Listeria monocytogenes, and Escherichia coli. When the wet noodles containing Prunus mume juice were kept at $4^{\circ}C$ for 20 days, it was showed that the drop of pH was not significantly occurred during the storage. Total microbial counts for control exceeded the initial putrefactive criterion level of $1.0{\times}10^6\;cfu/g$ at 16 days of storage at $4^{\circ}C$. However, total microbial count of wet noodles with the addition of 10%, 20% and 30% Prunus mume juice were $3.0{\times}10^2\;cfu/g,\;3.0{\times}10^2\;cfu/g,\;and\;1.5{\times}10^2\;cfu/g$, respectively, and these bacterial counts were still less than the criterion level ever at 20 days of storage. The addition of Prunus mume juice extended the shelf-life of wet noodle appreciably.

  • Underwater wet bead-on-plate welds were experimentally performed on 11mm thick SS400 steel plate as base metal by using six different types of flux coated electrodes of 3.2mm diameter. Two kinds of different flux coated wet arc electrodes (UW-1, UW-2) were individually designed flux materials, three kinds of the electrodes (E4301, E4311, E4313) were terrestrial electrodes and the another one (TN20) was an imported underwater wet welding electrode. As results, the individually designed flux coated underwater electrode, UW-2 and TN20 had a good starting and the excellent arc stability compared with other electrodes. No significant difference of bead appearance could be detected, but the slag detachability of TN20 electrodes was relatively undesirable. By rapid cooling rate, the hardness value and the portion of martensite of HAZ were increased, but it was considerably maintain stable for TN20 and UW-2 electrodes. The individually designed flux coated electrode, UW-2 could be used in practice for underwater bead welds.
