A study on the upper garment of Korean women, JUORI The upper garment of Korean women. JUGORI, is an inherited mode from the ancient clothing style in the various aspects based on the particulars of Korean clothes. The ancient style of clothes is originated from KWAMDUI belonging to inhabitants of Northern Territory of Korea. And it is quite different from Chinese clothes in lineage. However, this unicque mode of clothes has been much influnced by the Chinese culture and also by the climate of Korea. And it is quite different from Chinese clothes in lineage. However, this unicque mode of clothes has been much influnced by the Chinese culture and also by the climate of Korean penynsula. The changes of the pattern of JUGORI, in a word, is a sign of shortening tendency of size. This tendency of JUGORI is remarkably seen in the shortening of length and other parts are decreased in size. The JUGORI in the ancient age was fallen below the weist of woman, which is similar to Robe, and was worn with band. However, the length of the JUGORI has been gradually shortened, and therefore, GORUM took place of the band. The shortening tendency of JUGORI is seemed to be shown its sign in the initial time of its origin, because there are some evidences that the women in Sylla Dynasty, and this tendency has been much expedited during the period of Koryu Dynasty with influences of Monggorian culture (Won Lynasty of China) The oldest sample for data of JUGORI in nowaday is one the remains of Yi Dynasty, and this sample for data provides all the particulars of the modern pattern of JUGORI. The tendency of JUGORI had been continued even in Yi Dynasty, and at the end of the Dynasty, the clothes was shortened that the women felt inconvenient wearing it in the status of the shortened JUGORI which was even hardly cover the initial time of epoch of modernization induced from the Western civilization, and after 1920s and 1930s JUGORI become a larger tendency. This is a sing of revival of practical use and rationalization of JUGORI become a shortening tendency again, and the size is similar with that of early age of Yi Dynasty. Instead of these similarities, the particulars of modern JUGORI is weighing on much emphasis on curve beauty and expression of experior beauty. The reason is that, together with westernization of clothes, JUGORI became a special pattern of clothes as a traditional Korean women wears. The very thing explaining this pattern of JUGORI is the "ARIRANG DRESS". And there are some fashion using button instead of GORUM and half sleeve JUGORI for summer use which is regarded as a part of improved aspect of life in Korea. in Korea.

Construction projects are based on the actual field, so if the construction schedule that is established in the construction plan is delayed or extended for various reasons, construction companies are vulnerable to claims, and thus strive to complete a building within the planned timeline by shortening the construction time. Therefore, this study surveyed technicians in apartment construction in Gwangju, and studied their perceptions of the actual conditions of process control, construction time needs, goals, and methods. The results showed that the organization of the process control department and professional employees was lacking compared to other regions. The need for construction time was perceived as high, while the reduction of the construction cost was perceived as low. Regarding the reduction goal, they perceived highly the preparation for the delay of construction time and various claims, and for the reduction method, they mentioned the extension of working hours and the increase in employees. Based on the results of this study, technicians should consider that a reduction of construction time not only can make up for a delay in construction, but is also closely related to improvements in production through reduction of cost, and increased international competitiveness.

The Permo-Triassic Songrim orogeny in the Korean peninsula was a major tectonic event involving complicated continental collisions at the eastern margin of Eurasia. Based on the previous studies on the metamorphic and deformations features of the Songrim orogeny, this paper presents metamorphic and structural characteristics and timing of the Songrim orogeny in the Taebaeksan basin, and discuss about correlation of the tectono-metamorphic evolution of the Taebaeksan basin with the Okcheon basin and the Imjingang belt with a combined analysis of bulk crustal shortening direction, metamorphic P-T and T-t (time) paths. The metapelites in the Pyeongan Supergroup in the northeastern margin of the Taebaeksan basin have experienced lower-temperature/medium-pressure (LT/MP) regional metamorphism followed by high-temperature contact metamorphism due to the Jurassic granite intrusion. The earlier LT/MP regional metamorphism produced two loops of clockwise P-T-d (deformation) paths combined with four deformation events ($D_1-D_4$). The first loop concomitant with $D_1$ and $D_2$ occurred at $400-500^{\circ}C$, 1.5-3.0 kbar, and related with growth of syn-$D_1$ chloritoid and andalusite, post-$D_1$ margarite, Ca-rich syn-$D_2$ or post-$D_2$ plagioclase. The second loop accompanying $D_3$ and $D_4$ occurred at $520-580^{\circ}C$, 2.0-6.0 kbar, and associated with the growth of syn-$D_3$ garnet and staurolite, and syn-$D_4$ and/or post-$D_4$ andalusite porphyroblasts. Furthermore the syn-$D_1$ chloritoid and andalusite porphyroblasts grew during E-W bulk crustal shortening, whereas the syn-$D_3$ garnet and staurolite, and the syn-$D_4$ and/or post-$D_4$ andalusite porphyroblasts have grown under N-S bulk crustal shortening. The similarity in the characteristics and timing of the metamorphism and bulk crustal shortening directions between the Okcheon and Imjingang belts suggest that the peak metamorphic conditions tend to increase toward the western part (Imjingang belt and southwestern part of the Gyeonggi Massif) from the eastern part (Taebaeksan basin). The E-W bulk crustal shortening influenced the eastern part of the Okcheon belt, whereas the N-S bulk crustal shortening resulted in strong deformation in the Imjingang and Okcheon belts. Consequently, the Permo-Triassic Songrim orogeny in the Korean peninsula is probably not only related to collision of the North and South China blocks, but also to the amalgamation of terrane fragments at the eastern Eurasia margin (e.g., collision of the Sino-Korean continent and the Hida-Oki terrane).

To investigate the effect of boning time and storage temperature on meat quality of duck breast, a total of thirty duck breasts were designed in frozen-thawed, chilled-storage, and cold-boning samples. No significant differences were found among pH of all samples. However, cold-boning samples showed significantly (p<0.05) lower cooking loss than the other samples. Frozen-thawed samples showed significantly (p<0.05) higher lightness ($L^*$) and yellowness($b^*$), shorter sarcomere length and higher shear force values compared to the other samples. The result speculated that muscle shortening was affected by lower temperature (frozen) hence tenderness was decreased. Sarcoplasmic protein solubility showed no significant differences among samples, whereas cold-boning samples showed significantly (p<0.05) higher myofibrillar and total protein solubility than the other samples. The result of sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) patterns, chilled-storage and cold-boning samples showed degradation at high molecular protein (nebulin), which was not observed in frozen-thawed samples. Therefore, this data suggested that muscle shortening, tenderness and protein degradation are not affected by boning time rather affected by rapid change of temperature in frozen-thawed samples.

Tonic smooth muscle exhibit the latch phenomenon: high force at low myosin regulatory light chains (MRLC) phosphorylation, shortening velocity (Vo), and energy consumption. However, the kinetics of MRLC phosphorylation and cellular activation in phasic smooth muscle are unknown. The present study was to determine whether $Ca^{2+}$-stimulated MRLC phosphorylation could suffice to explain the agonist- or high $K^+$-induced contraction in a fast, phasic smooth muscle. We measured myoplasmic [$Ca^{2+}$], MRLC phosphorylation, half-time after step-shortening (a measure of Vo) and contractile stress in rabbit urinary bladder strips. High $K^+$-induced contractions were phasic at both $22^{\circ}C$ and $37^{\circ}C$: myoplasmic [$Ca^{2+}$], MRLC phosphorylation, 1/half-time, and contractile stress increased transiently and then all decreased to intermediate values. Carbachol (CCh)-induced contractions exhibited latch at $37^{\circ}C$: stress was maintained at high levels despite decreasing myoplasmic [$Ca^{2+}$], MRLC phosphorylation, and 1/half-time. At $22^{\circ}C$ CCh induced sustained elevations in all parameters. 1/half-time depended on both myoplasmic [$Ca^{2+}$] and MRLC phosphorylation. The steady-state dependence of stress on MRLC phosphorylation was very steep at $37^{\circ}C$ in the CCh- or $K^+$-depolarized tissue and reduced temperature flattend the dependence of stress on MRLC phosphorylation compared to $37^{\circ}C$. These data suggest that phasic smooth muscle also exhibits latch behavior and latch is less prominent at lower temperature.

The vertical members of structures are shortened as time goes on. Because structures have been high-rising and atypical there should be different axial loads among vertical members and it causes differential column shortenings. The differential column shortening add stresses to connections, make slab tilt, and damage to non-structural components. To reduce these influences compensation is need. The rational compensation means the exact expectation of amounts of column shortenings and the reasonable corrections. The expectation of column shortenings are more exact as researched, however, there is little research about the compensation. This paper presents the average correction method and the constraints for differential column shortenings considering errors due to the construction precision. The relations between constraints and the number of correction groups give an objective criterion for decision of constraints.

Germinating ability of green seed in maturing period was investigated to develop the technics on generation shortening. Rapeseed did not germinate until 40 days after flowering (=DAF) in green seed and 50 DAF in dried seed. Effective germination to be utilized for generation shortening came on 55 DAF for dried seed by heating and on 75 DAF for green seed. The periodic time of seed dormancy in maturing period had two cycles and rest period was considered that it was different according to the ecological types of early, middle and late maturity.

Recently, Many studies have been undergoing to reduce a working time in a field of machine tool. There are two ways of reducing working time; to reduce actual working time by heighten spindle speed and to reduce stand-by time by shortening tool exchange time. Automatic tool change system belongs to the latter case. Fixed address type automatic tool change system that is being developed in this study can store more number of tool in small space than magazine transfer type automatic tool changer as well as shorten tool exchange time. In this paper, a simplified equivalent model of finite element method in order to analyze frame structure of fixed address type automatic tool change system is presented.
