This study was conducted to find out effect of microorganisms added for decomposition of organic matter when manufacturing compost. The microorganisms used were EM, LACTO, SEMIP, BAIMUD circulated in market and 068065 developed in Institute of Agricultural Sciences. Effect of microorganisms inoulation on rice straw was summarized as follows: The number of bacteria, actinomycetes and fungi was 28.7∼76.7(×106), 0∼72.0(×106) and 0∼198.7(×105)cfu/g respectively. The number of bacteria, actinomycetes and fungi between microorganisms was no different.

The dynamic mechanical properties of thermotropic liquid crystalline polyester (LCP) blends with polystyrene (PS) and Li sulfonated polystyrene (PSSLi) were investigated. It was found that PS forms an immiscible blend with LCP. However, above the matrix T_(g) of the PS, the addition of the LCP increases the modulus of the blend significantly because the LCP acts as filler below its T_(g). In PSSLi/LCP blend system, it was also found that, in the temperature range between two T_(g)s of the ionomer, the LCP acts as filler and thus increases the modulus of the blend. However, the filler effect of the LCP on the modulus decreases rapidly with increasing temperature and disappears above the T_(g) of the LCP. Finally, it was suggested that the PSSLi may be partially miscible with the LCP via ion-dipole interactions between a Li^(+) cation of the PSSLi and a carbonyl group of the LCP.

Purpose: The proportion of centenarians has been increasing in many parts of the world, and the issues of longevity has been the subject of the research concern in recent years. We has conducted the first study with centenarians in Busan, 2006 and this is a follow-up study for prospective research of centenarians in Busan. Methods: The demographic database of Busan Centenarian Study existing in 2006 wasutilized for our studies. Twenty-five centenarians or a proxy were contacted and eight individuals agreed to have a direct interview using a questionnaire. Data were collected from May to June 2007. Results: Of the 2Scentenarians, 2(8%)were men and 23(92 %) were women. The average age was 101.3 years and the highest one was 106 years of age. The majority of the centenarians were living with family, most of those were living with their sons. Among 8 visited centenarians, there were 2 drinkers(2S%) but no one was smoking. Among them, 7 centenarians (87.5%) had regular eating pattern and, 3 centenarians(37.5%) participated social activities. Conclusions: The centenarian in Busan is likely to be healthy and they are living with their family. The centenarians study in Busan has important meaning to understand the health of centenarians.

장혜진,유희석,임윤경,문세희,장기홍,이정필 대한부인종양 콜포스코피학회 2003 Journal of Gynecologic Oncology Vol.14 No.4

목적 : 재발성 난소암에서 platinum 감수성을 기준으로 2차 항암요법으로 사용한 Carboplatin과 Paclitaxel의 효과를 알아보기 위하여 본 연구를 진행하였다. 연구방법 : 1998년 1월 1일부터 2003년 8월 31일까지 만 5년 8개월 간 아주대학교병원 산부인과에 재발성 난소암으로 입원한 환자 중에서 최초 수술로 난소암을 확진한 후 Cisplatin 또는 Carboplatin 등 platinum 제재가 포함된 항암치료를 받은 후 6개월 이후에 재발한 환자 29명을 대상으로 Carboplatin은 5 AUC를 그리고 Paclitaxel은 175 mg/m^(2)를 투여하였으며, 최소 3회에서 최고 16회까지 투여하였다. 치료효과의 판정은 CT, MRI, Ultrasonography등 영상진단상 암종괴의 크기가 완전히 소실되었을 경우를 완전반응(complete response)으로, 50%이상 감소되었을 경우를 부분반응(partial response)으로, 50% 미만으로 감소되었거나 20% 미만 증가하였을 경우를 불변(stable disease)으로, 그리고 20% 이상 증가되었을 경우를 진행(progressive disease)로 정의하였다. 결과 : 대상 환자에서 완전반응은 6명(21%), 부분반응은 11명(38%), 그리고 불변은 5명(17%)로 전체 반응율 (overall response rate)은 59% 그리고 임상적 유용성(clinical benefit=CR+PR+SD)은 76%이었다. 결론 : 재발성 난소암환자에서 기왕에 사용한 Platinum 제재에 민감한 환자에서는 Carboplatin과 Paclitaxel의 병행 투여가 효과적이었다. Objective : To ascertain the effect of Carboplatin and Paclitaxel combination as a second line regimen for recurrent ovarian carcinoma based on platinum sensitivity. Methods : From January 1st, 1998 through to August 31st, 2003, 29 patients were retrospectively reviewed who had previously underwent primary cytoreductive surgery and adjuvant chemotherapy with Cisplatin or Carboplatin for ovarian carcinoma, and who had later recurred during follow up. All 29 patients had recurred at least 6 months after therapy, and thereafter received second line chemotherapy consisting of Carboplatin (5 AUC) and Paclitaxel (175 mg/㎡) for a minimum of least 3 cycles and a maximum of 16 cycles. Treatment efficacy was assessed by imaging studies including Computerized tomography, Magnetic Resonance Imaging, or Ultrasonography. Complete response was determined as complete disappearance of tumor, partial response at least than 50% reduction in tumor volume, stable disease as less than 50% reduction or less than 20% increase in tumor volume, and progressive disease as more than 20% increase. Results : There was complete response in 6 (21%) patients, partial response in 11 (38%), stable disease in 5 (17%), showing an overall response rate of 59%. The clinical benefit (CR+PR+SD) was 76%. Conclusion : The combination of Carboplatin and Paclitaxel administration seems to be an effective mode of second line therapy in patients with recurrent ovarian carcinoma who had been sensitive to prior platinum based chemotherapy.

신라화랑의 신체활동에 관한 연구

김진범,이인희,윤동식 대한무도학회 2000 대한무도학회지 Vol.2 No.1

This study aims to examine the background and die concrete physical activities of hwarang("flower of youth") of Silla for the purpose of deducing modem significance from a standpoint of the martial arts history. I have reached the following conclusions. First, the religious aspect of the hwarang was characterized by the factors of shamanism, taoism, and Buddhism. The actions of the hwarang as manifested in their physical activities originated from the ideological groundwork of the hwarangdo(hwarangship). The hwarangdo seems to have been based upon the racial tradition and belief for the express purpose of defending national territory and sovereignty by closely uniting and specially training the elite youth so that they could be of great use to the country not only militarily but socic-politically as well. When in perfect alignment with this supreme policy of the state, the hwarangdo seems to have functioned as the strongest internal movement - national movement. The central ideology of the hwarangdo were loyalty, filial piety, and mutual trust. Second, the physical activities of the hwarang may be classified into three categories - hunting, singing and dancing, and martial art. Hunting includes political and military methodology. Some hunting pictures of the Silla dynasty, however, showed scenes akin to recreation. Third, the physical activities of the hwarang had a close relation with education. It is worth notice that in training the hwarang not merely physical education but also moral and musical education were placed great importance on. On of the educational objectives in training the hwarang was apparently to produce Hercules or warriors that were m great demand in the country and society. The hwarng was supposed to be a youth of perfect health and undaunted courage and one who boldly stood up to an injustice. In short, the ideal the hwarang sought was to become a balanced personality with sufficient intellectual and emotional cultivation as well as being a master of martial arts by constantly practicing physical training.
