  • It is known that there are two Gabong taesil (shrine for King's umbilical cord) of King Danjong, the 6th king of Joseon, remaining today. One of them is Mt. Sogok in Sacheon-city, Gyeongsangnam-do and the other is Mt. Beomnim in Seongju-gun, Gyeongsangbuk-do. The academic sector argued about this matter as there cannot be two Gabong taesil for one king. I once argued that Taesil on Mt. Beomnim in Seongju is King Danjong's Gabong taesil and Danjong taesil in Sacheon is the one for Prince Inseongdaegun, the eldest son of King Yejong. At that time, however, I had not examined the archaeological relics found in these places. In result of making an archaeological approach, I have come to the following conclusions :1. King Danjong had two Taesil : Agi taesil(shrine for baby's umbilical cord) and Gabong taesil. The first Agi taesil was created on Taebong of Mt. Seonseok in Seongju on November 26, 1441, but was moved to Mt. Beomnim in Seongju in 1451 to form the second Agi taesil. In 1458, King Sejo eliminated his Taesil. The stone structures of Gabong taesil still remains on Taebong of Mt. Beomnim, so it has been assumed that King Danjong established them during his reign (1452-1455). 2. Taesil in Sacheon has been known as King Danjong's Taesil because of King Danjong's reinstatement during the reign of King Sukjong. His Taesil was repaired with the reinstatement and King Sukjong was mistaken that Taesil in Sacheon was King Danjong's Taesil to fix it. The time of restoration has been assumed to be soon after the restoration of King Danjong's tomb (1699-1719). Taesil is missing the book of records and rails around the stone structure because the tombs of reinstated kings were restored without rails. 3. It is incorrect that Taesil in Sacheon was known as King Danjong's Taesil, It has been concluded that this Taesil was for Prince Inseongdaegun who was born in 1462. I focused on the fact that Prince Inseongdaegun's Taesil was in Seosamneung Taesil instead of King Danjong's Taesil. When Yiwangjik stored King Danjong's Taesil in Seoul in 1928 and moved it to Seosamneung in 1930, he found that the epitaph on the tombstone recorded that it was Prince Inseongdaegun, not King Danjong, and created Prince Inseongdaegun's Taesil in Seosamneung. I referred to "Taebong", which was created when Seosamneung Taesil was built during the Japanese imperial rule over Joseon, and the relics found in Taesil in Sacheon and Seosamneung.

  • The Sewability was tested with the seam strength and Puckering Grade by a general sewing machine according to some properties of simulated Leather, yarn tensile strength needle and stitches. The main results tested are as follows ; 1. The thick and uncomfortable leather is unable to be sewed by a general sewing machine, but the thin and soft one is able to. 2. The interval between stitches depends on type of leather used, and the variance in accordance with type of leather varies much more in the case of narrower interval. 3. When the sewability of leather-surface is not so good, is desirable to pour oil on the surface for the purpose of better efficiency. 4. The seam strength is directly proportional to interval of stitch and tensile strength of yarn and leather used, and needle No. 14 is more effective than No.1l. 5. The more the soft and thin leather is, the lower the Puckering Grade becomes. Type of yarn and interval of stitches do not seem to effect the Puckering Grade.

  • The experiment was conducted on five different kinds of fabrics dyed with loess. The sewability of fabrics dyed with loess by measuring the maximum needle piercing forces(MPF) through fabrics has been studied, MPF measurement using tensile tester was done 60 times for each fabrics at fixed low speed of 300mm/min. The nature of the loess on the dyed fabrics was physically jammed betweenthe fibers or adhered to the surface of fibers in the form of the fine particles so that the MPF through fabrics increases extremely in proportion to the increase of loess uptake and the plying number of fabrics dyed with loess. This results indicate that the MPF through fabrics is affected by mean value of the coefficient of friction on the surface of fabric(MIU) and cloth cover factor(Kc) in this experiment. Fabric was finished with softner to decrease the MPF during sewing operation, The MPF through softner finished fabric was decreased remarkably.

  • This study has investigated the relation between the sewing speed and seam breaking strength applied perpendicular to the seam direction. Breaking strength efficiency breaking mode of seams were examined under various sewing conditions using three kinds of sewing threads and four kinds of fabrics. The results obtained are as follows : 1. According to the increase in sewing speed seam strength was remarkably decreased. Seam strength and its loss difference were shown variously as threads and fabrics were mixed. 2. In case of fabrics with higher strength seam strength showed higher. And the seam strength was determined by the loop strength. 3. In case of fabrics with lower strength seam strength and its difference for every sample showed lower. So the strength of fabrics dominated the seam strength than those of threads. 4. In the experiment using various fabrics and sewing threads there was a type of thread appropriate to each fabric. Fabrics and threads with have similar physical properties were shown proper seam efficiency. 5. The breaking mode was different for every sample seam that was tested.

  • In this study, for different test methods of the performance of sewing threads were used to evaluate the sewability of 10 different industrial threads. Sewability evaluations related to the breakage of thread during sewing operation were investigated by seam length and fabric thickness method (Test 1), thread tension method (Test 2), strength retention method (Test 3), and backward sewing method(Test 4), and discussed. Two of the methods, Test 1 and Test 2, simulated very harsh sewing conditions which each thread could accept as an evaluation of its sewability. Core spun thread ranked with the best sewability generally and followed by air jet textured (ATY) thread. Spun thread was superior to the filament thread in sewing thread type. In general, there was a high degree of correlation in the results of Test 1 and Test 2. The order of sewing thread by sewability test 1 was polyester spun thread, cotton thread, and p/c core spun thread. The order of sewing thread by test 2 was polyester spun thread, and p/c core spun thread. Cotton threads and cotton blended threads performed better in Test 3, and ATY threads and core spun threads in Test 4.

  • The purpose of this research was to compare the microtensile bond strength of resin coated surface and resin inlay according temporary filling materials prior to applying self-adhesive resin cement. Caviton(GC, Japan), Provifil(Promedica, Neumunster, Germany), Provifil(Promedica, Neumunster, Germany) & petrolatum, and Eugenol-based cement, Tembond(Kerr, Orange CA, USA) were used as temporary filling materials. After fabrication of Tescera(Bisco, Schamburg IL, USA), it was bonded with a self-adhesive resin cement, Rely X unicem(3M, St. Paul. Minn, USA). After this procedure, the microtensile bond strength was measured and it was analyzed through one-way ANOVA and Duncan test(p<0.05). Caviton(GC, Tokyo, Japan) showed statistical difference except for the control(group I) and the saliva(group II)(p<0.05). Provifil(group IV), Provifil & petroneum(group V), Tembond(group VI) had lower microtensile bond strength.

  • The purpose of this study was to research the effect of sewing threads on sewability. The materials used in this study were cotton threads, p/c spun thread, polyester spun thread and core-spun thread, which were the same in count, but different in fibers. In order to approach the purpose of this study, the change of sew-ability was measured according to the number of laundering. The results from this measure were as follows; 1. The order of seam strength according to the sewing threads was polyester spun threads, p/c spun thread, core-spun thread, and cotton thread in proportion to the loop strength of the sewing threads. The preserving rate of strength after laundering was the highest in core spun thread. 2. The order of seam elongation according to the sewing threads was polyester spun thread, p/c spun thread, core-spun thread and cotton thread in proportion to the elongation of the sewing threads. The preserving rate of elongation after laundering was the highest in core spun thread. 3. The order of seam puckering according to the sewing threads' was core-spun thread, p/c spun thread, polyester spun thread and cotton thread. The order of changing rate after laundering was the same as the former order. 4. The order of the needle temperature according to the sewing threads was polyester spun thread, core-spun thread, p/c spun thread and cotton thread.

  • The World Heritage Subcommittee of the Cultural Heritage Administration which examine The World Heritage Subcommittee of the Cultural Heritage Administration which The World Heri The World Heritage Subcommittee of the Cultural Heritage Administration which examined the Placenta Chamber of King Sejong's Princes applied for the world heritage priority list in 2020 recommended expanding it to the royal placenta chambers of Joseon distributed nationwide for successive registration instead of registering the Seongju placenta chamber only. On account of that, the issue of selecting items has become one of the important topics to be discussed in the registration of world heritages. Accordingly, this researcher investigated the subjects of successive registration based on such conditions as excellent universal value, heritage protection and management, authenticity, and completeness among the real estate cultural properties demanded by the UNESCO World Heritage Committee. First, 22 placenta chambers, the real estate cultural properties designated as cultural properties and protected and managed by the state and local governments, are subject to it. Second, it seems that placenta chambers that can be restored through research and historical investigation and become designated as cultural properties can additionally be added. Third, items such as the Seosamneung Royal Tombs built by Lee Wang-jik in the Japanese colonial era or Seongjong Placenta Chamber relocated as an example to realize the completeness of Joseon's Royal Placenta Chambers can be included as well. Meanwhile, many of the items designated as cultural properties are not in the original location, and they can be divided into those that were relocated for the intentions of the Japanese Empire and those that were not. Therefore, the researcher insists that it is necessary to select and add items with which we can understand the historicity in the relocation of placenta chambers during the Japanese colonial era and also to quickly designate those that have not been designated as cultural properties yet. Therefore, regardless of designation as cultural heritage, local governments must promote both restoration and designation and strive to include them in the list of successive registration of world heritages grounded on thorough historical investigation. Moreover, to add them to the list of successive registration of world heritages, the Cultural Heritage Administration and local governments should promote continuous research and genuine restoration of individual placenta chambers.
