In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

A clinical study of selected patients with intraoral squamous cell carcinoma which were managed in the Department of Oral Oncology of Korea Cancer Center Hospital from January 1982 to August 1989 was done. And following results were obtained. 1. Males were involved more than females by intraoral squamous cell carcinoma in a ratio of 4:1. and most of the cases occurred in the 7th and 6th decades (69%). 79% of total patients and 92.5% of males were. 2. The mean duration of symptomatic period was 5.9 months. 3. The common symptoms were swelling (63%), pain (40%), ulceration (33%), and trismus (23%) 4. In the histologic findings, well differentiation comprised 58.0%. 5. The primary sites were the upper alveolar mucosa (32%), the floor of the mouth (21%), the lower alveolar mucosa (19%), tongue (14%), retromolar trigone (8%), palate (7%) and buccal mucosa (3%). 6. According to TNM system, Stage I, Stage Ⅱ, Stage Ⅲ, and Stage Ⅳ comprised 4%, 15%, 32%, and 49% respectively. 7. In the management of intraoral squamous cell carcinoma, surgeries were done in the 32 cases, 23 cases of which were managed by radiation therapy or chemotherapy concurrently. And radiation therapy alone was received in 35 cases. 8. Overall 3 and 5-year survival rates without regarding to stage were 27.6% and 21.4%. 9. 3-year survival rate of female patients was 47.2% and that of male patients was 22.6%. 10. 5-year survival rate was 53.9% for “early”cancer (stage I and II) and 15.6% for “advanced”cancer (stage Ⅲ and Ⅳ). Survival rate of patients in the early stages of cancer appeared to be higher than that of patients with stage Ⅲ and Ⅳ(p<0.05).

This was studied on working efficiency of power tiller (CT-83.N-6). Working power of power tiller(average horse power 6Hp. maximum horse power 8Hp) was operated three times in plow work(depth 15 cm, Cross size 60cm), which was chosen on clay loam field. Resuelt as following. ①The efficiency of power tiller`s was observed 2∼2.5 times to animal power(Cow), and needed 2l of fuel p/h. ②High speed on read was observed 14.6 per hour. ③Gravity position of power tiller is apt to decline where the main clutch was atta-ched, so it needs much attention in operating.

A Genealogical Approach to the Incoterms Rules and Revised Incoterms 2010

Jae‐,Hwan Chung,Bong‐,Soo Lee 한국무역학회 2013 Journal of Korea trade Vol.17 No.2

Incoterms have provided a set of rules that the global trade community can use for the interpretation of shipping terms. Always viewed from the perspective of the seller’s delivery obligation, Incoterms focus on the responsibility for the risk of loss or damage to the goods sold, division of transportation and customs‐related costs between the seller and buyer, and the obligation to execute certain functional activities related to the movement of the goods. The ICC has consistently attempted to update Incoterms in a way that keeps pace with the evolution of business practices. The ICC recently published the new listing of terms, which hints at some of the significant changes ahead in the new publication. It is not certain how the Incoterms 2010 have been used in practice, so it is difficult to find out related problems. Therefore, those who are unwilling to use Incoterms 2010 are free to choose Incoterms 2000 or other trade terms. However, this kind of practice can cause a conflict because of differences in the interpretation of trade terms in international trade. It would be desirable to use Incoterms 2010 based on the revised Incoterms 2000. It is still unclear how predominantly Incoterms 2010 will be used in international trade. Of course, it is necessary to keep updating trade terms based on a deeper analysis on the matters associated with the Incoterms rules, and maintain an understanding of contemporary changes. In this context, this thesis aimed to investigate the historical background of the Incoterms rules and find out how t

Hypopharyngo-esophageal cancer is usually found at late stage. Its main treatment is surgical intervention and it often requires radical resection. Reconstruction of the hypopharyngo-esophageal defect after the resection of carcinomas of the hypopharynx and the cervical esophagus has traditionally been carried out with deltopectoral or musculocutaneous flap. Another approach is to reconstruct the defect with the colon or stomach. Recent advances in microvascular surgical techniques have resulted in one stage reconstruction with free flap. Both jejunal free flap and radial forearm free flap is a good alternative for the reconstruction of hypopharyngo-esophageal defect. Six cases of the radial forearm flap and nine cases of the jejunal flap were used to reconstructed the hypopharyngo-esophageal defect in 15 patients. In jejunal free flap, upper margin was reconstructed with end to side anastomosis and lower margin with end to end anastomosis. In radial forearm free flap, we used trapezoid shaped flap and tubed by complete or partial tubing according to the condition of the defects. Stricture and fistula are troublesome complications. The complications were peritonitis(n=1) and fistula(n=1). We concluded that both forearm and jejunal free flap is a useful alternative in reconstruction of hypopharynx and cervical esophagus.

Direct Methanol Fuel Cell (DMFC) is based on the technology of Polymer Electrolyte Membrane Fuel Cell. DMFC has several features of environmentally benign generation of electricity and high mobility for portable electronics etc., but its main problem to overcome for commercialization is the high cost of noble metal catalysts. In this study, it was found that the Pt/C catalyst supported on carbon nano fiber had the highest catalytic activity among the catalysts supported on several carbons. The newly developed Pt/C alternative catalyst had higher catalytic activity for methanol oxidation than the Pt/C catalyst supported on Vulcan XC-72.

This study was carried out to compare a yield performance about CNU maize hybrids developed at the Maize Genetics and Breeding Lab, in Chungnam National University. Among the hybrids incorporated in the test, CNU 3 and 1 showed higher dry matter per 10a and lower kernel yield per 10a than check hybrid, Kwanganok. Hongchon 5 and Suwon169 showed higher kernel yield than Kwanganok. The average yield of CNU 3 hybrid in dry matter and CNU 4 in kernel yield were 2,106kg/10a and 854kg/10a in regional adaptability test, which were increased 33% and 8% compared with a check hybrid, respectively. Also, these hybrids had better stay green characteristics than check hybrid and showed moderately resistance to corn borer and leaf spot.
