This study is based on the observation of women's Jangui in 17th centuries. As we observed, Jangui in seventeenth century was shown the same style. They were not headdress but coat. The characteristics of shape are Mokpankit, double-seop, straight sleeve, triangle moo, sam-su(which is attached to the end of sleeves) and a little coat string etc. There is no specific mode difference with the change of times. However, the straight sleeve is shown straight line in the early Chosun dynasty. Jangui in seventeen century are all oblique line sleeve except Jangui of Jin-ju Ha's family. Jangui put on coat do not seem clear-cut difference with the change of times. From Jangui of Yang-chun Hu's family in 14th centuries till An-dong Kim's family, the special features of Jangui are the same style. In addition, The double-seop in 17th centuries was not completely symmetry. However, after 19th centuries, Jangui for headdress was shown perfectly symmetry.

The promising characteristics of 2G high-temperature superconductor (HTS) coated conductor (CC) tapes have made it possible to apply to various electrical device applications. In this study, the mechanical and electromechanical properties of Sn-Cu double layer stabilized GdBCO CC tapes have been characterized. The stress and strain tolerances of $I_c$ in GdBCO CC tapes adopting stainless steel substrate were evaluated using $I_c$-strain measurement at 77 K under both uniaxial tension and monotonic bending conditions. The results were compared to the conventional single Cu layer stabilized CC tape. As a result, the Sn-Cu double layer stabilized GdBCO CC tapes showed somehow lower or comparable electromechanical properties as compared to the Cu stabilized CC tape ones.

Double pipe system in which PB pipe is inserted in CD pipe buried in the concrete slab is widely used for cold and hot water supplies in apartment housings. The system, however becomes complicated and the overlaying pipes in the concrete slab weaken the compressive strength of the slab. Also, insufficient insulation increases energy loss. In this work, the problems of the double pipe system are studied and plans A, B, and C are suggested for improvement. In terms of compressive strength of the concrete slab, plan A(total pipe length 73 m) was the weakest and plan B(2 m) was the strongest. Energy loss of plan A was the largest with 558.9 W and plan B was the lowest with 220.7 W. However, considering the combined effect of strength and heat loss, plan C becomes the best choice, which retains the advantage of the double pipe system.

One of the important roles of a DNA chip is the capability of detecting genetic diseases and mutations by analyzing DNA sequence. For a successful electrochemical genotyping, several aspects should be considered including the chemical treatment of electrode surface, DNA immobilization on electrode, hybridization, choice of an intercalator to be selectively bound to double standee DNA, and an equipment for detecting and analyzing the output signal. Au was used as the electrode material, 2-mercaptoethanol was used for linking DNA to Au electrode, and methylene blue was used as an indicator that can be bound to a double stranded DNA selectively. From the analysis of reductive current of this indicator that was bound to a double stranded DNA on an electrode, a normal double stranded DNA was able to be distinguished from a single stranded DNA in just a few seconds. Also, it was found that the peak reduction current of indicator is proportional to the concentration of target DNA to be hybridized with probe DNA. Therefore, it is possible to realize a sim71e and cheats DNA sensor using the electrochemical measurement for genotyping.

Noonan syndrome is characterized by typical facies, congenital heart defect, and some clinical features similar to Turner syndrome, but with normal chromosomes. The most commonly associated cardiac defects are pulmonary valvular stenosis and strial septal defect. We experienced a case of Nonan syndrome associated with pulmonay valve stenosis with double-chambered right ventricle and atrial septal defect and cryptorchidism. Pulmonary valvotomy was done through transannular incision. Hypertrophied muscle bundles were excised. Atrial septal defect was closed directly. RVOT was reconstructed with pericardial transannular patch. Orchiopexy was performed simultaneously without any problem.
