The Gollyongpo was worn by the King and the Crown Prince in Joseon dynasty as an ordinary wear. The research on the Gollyongpo is focused on the historic record of Joseon dynasty, Joseonwangjosillok. This study will analyze literature, paintings and relics. First, I have researched Ming's(China) representative document daminghuidian, and excavated relics from the tomb dingling. I examined the usage and characteristic, through various remaining literature data, artifacts and paintings. The Gollyongpo was worn for the various ceremonies as well as an ordinary wear. According to the periode, the style and color had changed. The King wore the red Gollyongpo with 5 clawed dragon pattern, the Crown Prince wore black one with 4 clawed pattern, and the eldest son of the Crown Prince wore black one with 3 clawed dragon emblem. After the Daehan Empire, the Emperor wore gold outfit and the Crown Prince wore red outfit. Sonyongpo recorded in the Gungjungbalgi is concerned as Gollyongpo with narrow straight sleeve, one of the Sejong University Museum's Collection. There is some Possibility that the Gollyongpo painted in Bongsado is woven with dragon design, I would leave this matter for next research task.

For the detection of heated milk, heated milk is possible to decide by use of various methods for example, rennet coagulation, scanning electron microscope, determination of SH radical, electrophoresis, spectrometry to 340nm. Among the above method, rennet coagulation time is frequently used because of simple and rapid. Heated milk to above 70 degree is possible to detect by use of rennet coagulation time. In future, it should more develope method which can be detect the heated milk on thermization of around 55 degree. It may be deviate the normal range by one test item in the detection of adulteration. For this case, skimming, water and salts addition can detect but in normal range, analysis of another items also should synthetically be side by side and detect, and it is necessary to detect adulteration.

In this work, nonlinear control of a three-phase shunt active power filter (SAPF) has been studied and compared to classical control based on proportional integral regulator. The control strategy is based on the direct current method using sliding mode control (SMC), where the aim is to regulate the average voltage across the dc bus of the inverter. Details are given for the control algorithm; the controller is comprised of a current loop which utilizes a hysteresis controller to generate the gating signals for the switching devices, and a nonlinear controller based on SMC law which is different from classical laws based on error between reference and measured output voltage of the inverter. Sliding surface applied in this work contains the whole of state variables, in order to ensure full control of the system behavior in the presence of disturbances that affect the supply source, the load parameters or the reference value. The designed controller offers advantage that it can gives the improvement of dynamic and static performances in cases of large disturbances. A comparison of the effects of PI control and SMC on the APF response in steady stat, under line variations, load variations, and different component variations is performed.

It is very important to improve the overall efficiency of systems with a source of power that has low-voltage high-current terminal characteristics such as fuel cells. A resonant converter is required for high efficiency systems. However, the peak value of the switches current is large in a resonant converter. This peak current requires a large number of switches and results in system failures. In this paper, an analysis and experiments of a resonant isolation push-pull converter are performed. A switching loss analysis is performed in order to compare losses between a resonant push pull converter and a hard switching push-pull converter. Specially, the conduction loss is studied based on the ratio between the resonant frequency and the switching frequency. In addition, a method for improving the efficiency is implemented with conventional HF insolation converters.

This study aims to substitute the emulsifier and gelifier for the poly phosphates with regard to diminishing the foreign phosphates in diet and production cost. It is desirable to introduce the application of theory for melting phenomenon in this investigation since the rate of peptisation is very representative index during the conversion of Ca-paracaseinate to Na-paracaseinate in processed cheese. It will be impossible to substitute completely for polyphosphates but partial substitution could be possible if one consider the organoleptic quality of typical processed cheese.

Online or e-banking has been adopted as key banking innovation in Uganda adopted by all financial institutions in the country. This research explored the state of e-banking and its efficacy in Uganda banking industry. A correlation analysis approach was adopted for this research. In Uganda, the banking sector has been liberalized with telecommunications allowed to effect e-banking and ecommerce transactions. The study concentrated on the periods of years 2011/2012 and 2012/2013. Findings from this research revealed that BOU uses UNISS for real time gross settlement (RTGS). Since its adoption a +1 coefficient correlation was realized. With the use of mobile money, also a +1 coefficient correlation was achieved for the period under consideration. As regards the use of e-cheques, there was a drop reflected by -2.8 percent which could have been attributed to perception of the users, though there was a +1 coefficient correlation when considering e-cheque transactions and the monetary value. The use of EFT in Uganda generated a +1 coefficient correction considering the number of users and the monetary value involved. Bank of Uganda should work hard and make or go live with electronic banking supervision software which would aid them with their supervisory roles.

Kublai Khan on a Hunting Trip were painted by Liu Guan-dao. This painting gives us very important information for understanding cosume of Yuan dynasty because of realistic description. We studied the name of costume of the king Shizu in this painting by using the way of comparison his costume with another paintings, the records and archaeological finds. This study showed that the costume of the king Shizu is judged to be Jisun, the traditional costume of Mongolian own meaning one colour. The name of each is the Yinshu warm hat, being making into the for of a kind of rodents, the Yinshu Jisun, the Red colour Jisun, being railed on the robe, and the Cloud boots cover. And we found that the decoration on the neck and sleeve tib of the Yinshu Jisun had been made by sable furs, and the decoration on the surface had been made by tails of them, going by the name of Rondes at that time. It also showed that the meaning of one colour of the Jisun is not only just appearing one colour on the one person but also being able to appear two set of one colour.

Cancer is a global health challenge with high morbidity and mortality rates. However, conventional cancer treatment methods often have severe side effects and limited success rates. In the last decade, extensive research has been conducted to develop safe, and efficient alternative treatments that do not have the limitations of existing anticancer medicines. Plant-derived compounds have shown promise in cancer treatment for their anti-carcinogenic and anti-proliferative properties. Rosmarinic acid (RA) and carnosic acid (CA) are potent polyphenolic compounds found in rosemary (Rosmarinus officinalis) extract. They have been extensively studied for their biological properties, which include anti-diabetic, anti-inflammatory, antioxidant, and anticancer activities. In addition, RA and CA have demonstrated effective anti-proliferative properties against various cancers, making them promising targets for extensive research to develop candidate or leading compounds for cancer treatment. This review discusses and summarizes the anti-tumor effect of RA and CA against various cancers and highlights the involved biochemical and mechanistic pathways.

In order to establish the experimental clinical model for evaluating the influences on the sexual hormones of SD-rat administrated with Methoxychlor(MET), it was dissolved in acetone and olive oil (1:19), which was administrated orally at doses of 200㎎/㎏ body weight/day for 7 days. The Testosterone value was measured in sera by Gamma Count with 1251 isotype, also weights of the body, testis and liver were measured for 15 weeks. Testosterone in the serum of intacted SD-rats was 0.51±0.43ng/㎖(n=5), but it was 0.69±0.18(n=2)ng/㎖l on 1 week. 0.28±0.05ng/㎖(n=2) on 3 week, 1.52±0.95ng/㎖(n=3) on 5 week, and 0.54±1.95 ng/㎖(n=3) 15 week post-dosing MET, respectively. Histologically, the numbers of spermatozoa and Leydig cells were reduced, which might influence to reduce sexual hormone, and AST and ALT was not increased in the serum due to administrating with MET, blood profile was not changed according to the administration of MET excepting MCH(Mean Corpuscular Hemoglobin). This study suggest that change of male sexual hormone by MET be a experimental model for evaluating some drugs associate with sex hormone.

Objective : Venous thromboembolism (VTE) after spinal surgery affects a patients' postoperative recovery and also carries a mortality risk. Some studies recommended chemical prophylaxis for high-risk patients and for those after complex spinal surgeries. However, chemoprophylaxis for VTE in spinal surgery is underemployed and there is no agreement on the use of VTE prophylaxis in spinal surgery. The aim of this study was to document the incidence of VTE after an elective instrumental spinal surgery, among those receiving preoperative chemoprophylaxis as compared with patients who did not receive it. Methods : This study was carried out on eighty-nine patients allocated randomly to receive either low molecular weight heparin (LMWH) or no prophylaxis before elective instrumental spinal surgery. All patients received postoperative compression stockings. A compression Doppler ultrasonography was performed for all patients to detect postoperative deep vein thrombosis. In addition, further imaging studies were performed for patients suspected of VTE. Results : Three (3.3%) patients were diagnosed with VTE. One of them had received preoperative chemoprophylaxis. There were no significant difference in incidence of VTE between the two groups (p>0.95; 95% confidence interval, 0.06-8.7). Laterality of gender and postsurgical recumbence duration were all independent predictors of VTE (p=0.01 and p<0.001, respectively). Conclusion : The difference in the incidence of thromboembolic complications between the two groups was not significant. Moreover, we found that preoperative prophylactic LMWH injection has no major bleeding complications altering postoperative course; still, the issue concerning the initiation time of chemoprophylaxis in spinal surgery remains unclear.
