Maize hybrids were planted on April 1, April 25, May 20 and June 15 in 2012, 2013 at the experimental paddy and upland fields in Suwon city , respectively to know changes of growth stage and yield according to different planting time. Maize planting on April 1 was not recommended because total growing days at planting on April 1 was not different with that at planting on April 25 due to many days from planting to emergence over 20 days at planting on April 1. Total growing days were not much different among three planting time after April 25 because days from silking to maturity was lengthened though days from planting to silking was shortened at later planting time. Stalk weight was decreased as planting time was delayed, particularly at planting times after May 20 at paddy field by excess water injury during early growth stage. But, grain yield was not low as in May and June. It is needed to introduce early maturity maize variety as Yanganok at late planting for higher grain yield and enough time for soil preparation for next winter crops

The effect of pigment-resin-solvent interaction on dispersion of pigment has been studied. The solubility parameter of TiO_2 pigment, determined in terms of suspension behavior of pigment in various solvents, was 10.27 (cal/cc)^1/2(δ_d = 8.23, δ_p = 3.45, δ_h = 5.10). The solubility parameter of Acryloid B-44, determined using rheological parameters of resin solution in different solvent, was 9.4 (cal/cc)^1/2. The solvent showing weaker interaction with pigment increased the adsorption of resin on to the pigment, resulting in higher dispersibility and higher storage stability of dispersion.

The hospice program provides palliative and supportive care to meet the special needs arising out of physical, emotional, spritual, social and economic stress which are experienced during the final stage of illness. This study is approached as following: First, Literatural review to hospice Second, Analysis of the hospice cases Third, Statistical data analysis The results of this study would be summarized as followings: (1) It is expected that increasing aged population and changing type of disease in particular, increasing of chronic diseases and cancers in Korea affects to present Health care systems. (2) There are two types of Hospice in Korea. One of them is Home visiting care type and the other is Hospice unit in the hospital. However, their activities are very feeble. (3) Before the regular enforcement to Hospice, it is needed prescription for the medical insurance coverage and the assignment of nursing fee. (4) The rate of cancer cases which appear in Busan is more than 10% of that of the Korean cancer appearance. However, there is no facility and little interest. Therefore, more study and a positive interest for Hospice should be demanded in Busan.

Granulocyte colony-stimulating factor(G-CSF) have been shown to hasten the recovery of neutropenia following anti-cancer chemotherapy. There are controversial opinions on the use of G-CSF in acute myelogenous leukemia(AML) because clonogenic studies have shown that G-CSF stimulates leukemic colonies as well as granulocyte colonies. In this study, we evaluated the effectiveness and safety of recombinant human G-CSF after induction chemotherapy with DAV regimen(Ara-C 100mg/㎡ day 1-8, Doxorubicin 45mg/㎡ day 3-5, VP-16 100mg/㎡ day 6-8) in 9 patients with AML. G-CSF therapy(200 ㎍/㎡/day) was begun 2 days after the end of chemotherapy and continued for 10 days. 17 AML patients who recieved the same chemotherapy before the onset of this study were used as historical control. G-CSF shortened the duration of granulocytopenia (less than 500/㎣) significantly (13 vs 23 days, p<0.001), but it had no effect on platelet recovery. Although the incidence of febrile episodes was almost the same, the duration of febrile episodes was shorter in the group treated with G-CSF( 5 vs 12 days, p=0.03). There was no evidence that G-CSF accelerated the regrowth of leukemic cells and the complete remission rates between the 2 groups were not different. These results show that G-CSF accelerates the recovery of granulocytopenia and shortens the febrile days after chemotherpy in patients with AML, without affecting the regrowth of leukemic cells.

In this study is behavior of crack propagation and fracture under static tensile load, shear load, rotary bending fatigue load in friction welded dissimilar materials. Crack was observed in fine ferrite zone of SM15C and heat affected zone of STS304. Plastic flow was occured by friction welding process, so direction of crack is inclined with welded surface. Fatigue fracture most occurred in SM15C heat affected zone around interface. Fibrous zone with the view of macroscope and dimple pattern with the view of microscope were observed at fracture surface. Result is more metal micrstructure dependence than stress dependence by mechanical and metallic mechanics.

To determine knowledge and recognition of the patients and the staffs on the cockroaches in hospitals, a survey was made toward them by using questionnaires from July 1994 to September 1994. The patients and the staffs were randomly selected for the survey from 6 hospitals which have over 200 beds in Pusan and Kyungnam area. The sample numbers of the patients and the staffs were each 150. However, 115 and 133 questionnaires from the patients and the staffs, respectively, were used for the data analysis. The results obtained were as follows. 1. The cockroach detection rate by the patients was 60.7% of them. The detection rates by female patients and the younger patients were significantly higher than those of male patients and the older patients(p<0.005). 2. 26.6% of the patients and 24.8% of the staffs have had allergies from the cockroaches. Also, 78.3% of the staffs have mentally suffered from nuisance by the cockroaches(p<0.05). 3. The degree of the knowledges on the cockroaches and the control methods were 70/100 at the patients and 69/100 at the staffs. Also, their knowledges were mainly obtained from mass media(45.0%). 4. The cockroach control was performed by 88.8% of the investigated hospitals and 55.1% of them contracted with the pest control operators to reduce the cockroach populations in the hospitals. The operators used mainly insecticidal baits for the cockroach control(47.0%). 5. The management and the education program for the cockroach control were required by the patients(80.5%) and the staffs(84.0%) in the hospitals.

Addition of EI systems to the synchronization networks is being conducted as the digital transmission in Korea is changing from TI to EI. In this study, the quality of the synchronization signal of DOTS's of each toll office which is under the early stage of transition to the EI synchronization networks is measured and analyzed. In particular, the purpose of this study is to find out how to speed up the deployment of the EI synchronization networks by comparing the quality of the TI and EI synchronization signals. According to the results, the TI and EI synchronization signals distributed from KRF directly have no difference in quality. In addition, the synchronization signal redistributed from DOTS which is phase-locked on KRF and the synchronization signal from KRF directly have no difference in quality. Hence, it is concluded that there will be no problems in quality of synchronization resulting from the gradual transition to El while making the most of the current TI facilities.

진행암 환자에서 Cisplatin 병용화학요법 시 Ondansetron의 오심 구토 조절 효과

조문준,윤환중,전의건,길준영,조덕연,김삼용 충남대학교 의과대학 지역사회의학연구소 1993 충남의대잡지 Vol.20 No.2

Ondansetron is a novel agent that selectively binds to the 5-hydroxytryptamine_3 receptor, and has been reported to have a prominent effect in the prevention of anti-neoplastic agent induced nausea and vomiting. Twenty solid tumor patients who were scheduled to receive cisplatin containing combination chemotherapy participated in a prospectively open-labeled study to evaluate the antiernetic efficacy and safety of ondansetron. The male to female ratio was 11 : 9 and median age was 49(16-70). The sites of primary neoplasms and number of patients were as following : head and neck 4, metastatic carcinoma of unknown primary site 3, stomach 3, osteosarcoma 2, ovary 2, esophagus 1, melanoma 1, penile 1, bladder 1, cervix 1, and extragonadal germ cell 1. Ondansetron was given as an 8mg loading dose IV before chemotherapy followed by 8mg IV every 8 hours until 24 hours after chemotherapy completion. Complete or major control(0 to 2 emetic episodes) of emesis was achieved in 17 of 20 patients(85%;complete 50%, major 35%) receiving ondansetron during the first 24hrs of chemotherapy. During the period of day 2 through clay 5 of chemotherapy, 14 of 20(75%) patients had complete or major control of emesis(complete 35%, major 35%). No severe side reactions were recorded in ondansetron treated patients, while mild to moderate headache was noted in 20% of patients. These results show that ondansetron is effective in the control of cisplatin induced nausea and emesis, and can be administered safely with minimal side effects.
