The purpose of this study was to find out the symbolism of religious costume which has showed the religious belief system through costume practice and culture. Indian Religious costume each has its own mark was investigated in this study. In India, religion is a way of life. It is an integral part of the entire Indian tradition. The results were as follows; India's several main religions are Hinduism(About 80% of population) , Islam (About 11% of population) , Sikhism(less than 2% of population) , Jainism(less than 1% of population) , Buddhism(less than 1% of population) and Christianity(About 3% of population but excluding here) Religious faith system which symbolized Godhood, spiritualty, ascetics, restraint, chastity, sacred and dignity gave a certain shape to each color, ornaments, dressing and marking of religion costume. In connection with religion costumes, there were Hindu's Tika, sacred ash, long hair, knot and holy band (Yajnopavita) , Buddhist's kayysa and tonsures, Jams' no covering, Muslim's chador and skullcap, Sikh's turban (with no cutting hair) , comb, steel bracelet, drawers, sword or dagger. The characteristics, head especially of thebody and white in the colors were made much account for India religion costume. Traditional costume seems to be worn at the present times in India. But apparently these costume associated with religion costume because of Hindu more than 80% of population.

In our country, which has a strong presidential system, the power and responsibilities of the president are truly enormous. He is the head of state and diplomatic representative, and at the same time exercises authority over all areas of the country, including the legislature, judiciary, and constitutional institutions, along with his responsibilities as head of the executive branch. Considering these aspects, it can be said that presidential records created during the president's rule have a high level of national and historical significance and value compared to other public records. Considering these importance of presidential records, the Presidential Records Management Act was enacted in 2007 to establish an institutional mechanism to systematically manage presidential records. However, the current institutional basis for appraisal of presidential records is very weak. In this regard, there is a need to begin discussions on the appraisal of presidential records in earnest. Considering the national importance and symbolism of presidential records, it is necessary to establish a new direction for appraisal of presidential records that is different from general public records. Accordingly, in this paper, as part of reestablishing Korea's presidential records appraisal system, this article analyzed the status and problems of the current presidential records appraisal system and presented directions needed to find future improvement measures. To this end, as a premise for discussing the importance and value of presidential records, it examined the powers and responsibilities of the presidency as defined in our country's Constitution.Next, we looked at the appraisal system and method for presidential records that are currently in operation, and then analyzed the problems that emerged here in connection with the characteristics of presidential records. Based on this, it presented five perspectives on issues that need to be discussed publicly in the records management community in order to reestablish Korea's presidential records appraisal system in the future.

Purpose: The purpose of this study was to evaluate the stability of abutment screws used with the zirconia fixture-based implant system and compare them with those used with the existing titanium fixture system via the finite element method. Methods: A single implant-supported restoration was designed for the finite element analysis. A universal analysis program was used to set 8 occlusal points along the direction to the long axis of the implant, and an occlusal load of 700 N was applied. Results: In all models (Zir and Ti-fixture model), the screw threads presented with the highest von Mises stress (VMS) values, whereas the head and end presented with the lowest VMS values. The VMS of the screw used in the zirconia-fixture model was 5.97% lower than that used in the titanium-fixture model (261.258 vs. 276.911 MPa, respectively) despite statistical significance. Furthermore, the zirconia fixture (352.912 MPa) had a higher stress value (8.42%) than the titanium fixture (332.331 MPa). In a completely tightened titanium fixture implant system, the stress was concentrated in the implant-abutment connection interface, the zirconia fixture presented with a stable stress distribution. Conclusion: Although the zirconia fixture demonstrated a high VMS value, owing to the stiffness and elasticity coefficients of the material, the stress generated in the abutment screws was similar in all models. In conclusion, the zirconia fixture-based implant system presented with a more stable stress distribution in the abutment screws than the titanium fixture-based implant system.

The purpose of this study is to introduce a new spacer damper for the bundle transmission lines network. It has the special design, the main characteristics and advantage of this new kind of spacer damper. An Existing spacer damper with bolted clamps, although widely used, is a method of connection with certain disadvantage both as regards assembly on the conductor and in the course of time. Even if tightening torque is correctly applied by using bolt with share head or torque wrench during working time, the aeolian vibration could involve untightening during life time, so the cable can move into the Jaws and wire's breakage appear. To salve this problems, France, Japan and other countries had developed a spacer damper with an automatic system through many years. This new spacer damper is an original automatic clamping device (beltless) which does not require special tool for its installation. This device prevents clamp unlocking problems, ensures a simple installation and ensures a reliable-tightening during life time. Therefore, it is necessary to localize this boltless spacer damper with automate clamping device.

Regardless of the prognostic factors in papillary thyroid cancer, such as sex, age, size of tumor, extent of disease, and distant metastasis, the prognosis of papillary thyroid cancer is sometimes difficult to predict from clinical and microscopic analysis alone and additional prognostic indicators are needed. Recent studies of thyroid cancer have indicated that DNA aneuploidy may be correlated to the biological behavior of malignancy and inversely correlated to the prognosis, but it still remains contraversal. We performed this study to assess DNA ploidy patterns in relation with the previously known prognostic factors in AMES scoring system and lateral neck node metastasis in papillary thyroid cancer. A series of 132 patients with papillary thyroid cancer and 80 patients with benign thyroid tumor(27 follicular adenomas and 53 adenomatous goiters) as a control group from October 1993 to Feburary 1995 were analyzed and their nuclear DNA content was measured with flow cytometry using fresh tissue specimens. DNA aneuploidy was found in 8(6.1%) in papillary cancer and 8(10%) in benign tumor. S-phase traction(SFP) and proliferative index(PI) were higher in thyroid cancers, being 2.18$\pm$4.24%, 6.34$\pm$4.94% in the papillary thyroid cancers and 1.97$\pm$2.93%, 4.44$\pm$3.80% in the benign tumors, respectively. However there was no significant difference of values between two groups(p>0.05). Among variable prognostic factors studied(age, sex, size of tun or, extent of disease, distant metastasis in AMES scoring system and lateral neck node metastasis), DNA aneuploidy was found to be common in distant metastasis(p<0.001) and in lateral neck node metastasis(p>0.035), but there was no significant difference between the high risk and low risk group according to the AMES scoring system(p<0.08). In our study, DNA aneuploidy was not valuable in determining the presence of malignancy and did not correlate to the AMES scoring system. However, follow-up study of more cases will be needed for accurate information about the DNA ploidy as a independent prognostic factor.

Objective : Craniovertebral junctional anomalies constitute a technical challenge. Surgical opening of atlantoaxial joint region is a complex procedure especially in patients with nuchal deformity like basilar invagination. This region has actually very complicated anatomical and functional characteristics, including multiple joints providing extension, flexion, and wide rotation. In fact, it is also a bottleneck region where bones, neural structures, and blood vessels are located. Stabilization surgery regarding this region should consider the fact that the area exposes excessive and life-long stress due to complex movements and human posture. Therefore, all options should be considered for surgical stabilization, and they could be interchanged during the surgery, if required. Methods : A 53-year-old male patient applied to outpatients' clinic with complaints of head and neck pain persisting for a long time. Physical examination was normal except increased deep tendon reflexes. The patient was on long-term corticosteroid due to an allergic disease. Magnetic resonance imaging and computed tomography findings indicated basilar invagination and atlantoaxial dislocation.The patient underwent C0-C3-C4 (lateral mass) and additional C0-C2 (translaminar) stabilization surgery. Results : In routine practice, the sites where rods are bound to occipital plates were placed as paramedian. Instead, we inserted lateral mass screw to the sites where occipital screws were inserted on the occipital plate, thereby creating a site where extra rod could be bound.When C2 translaminar screw is inserted, screw caps remain on the median plane, which makes them difficult to bind to contralateral system. These bind directly to occipital plate without any connection from this region to the contralateral system.Advantages of this technique include easy insertion of C2 translaminar screws, presence of increased screw sizes, and exclusion of pullout forces onto the screw from neck movements. Another advantage of the technique is the median placement of the rod; i.e., thick part of the occipital bone is in alignment with axial loading. Conclusion : We believe that this technique, which could be easily performed as adjuvant to classical stabilization surgery with no need for special screw and rod, may improve distraction force in patients with low bone density.

A circulation water channel with observational section of $4m{\times}2.4m{\times}1m(length{\times}breadth{\times}depth)$ and the maximum channel flow speed of 2 m/sec was designed for model tests of fishing gears. It consists of 6 sections evenly divided for easy connection. Two observational acryl windows of $1.2m{\times}1.5m$ and 2cm thick are provided. Steel deflection plates, equally spaced in 20-40cm, are fixed at corners of the channel to reduce the loss of water pressure head through the channel. The flow in the channel is controlled by D.C. motor control system with 50 H.P. driving propeller system. A series of model testing capabilities for fishing gear have been examined and the results are as follows. 1) The speed of water flow was in the range from zero to 2.3 m/sec. 2) The difference between the velocity of channel flow along the center line and that along both sides in the channel was less than 0.2 m/sec.
