As demands for micro parts are on the increase in recent industries such as aerospace, biomedical, electronics, environment, information technology and display, the need for manufacturing such parts is also increasing. Major methods of manufacturing micro parts are based on semiconductor process technology such as lithography and etching and non-traditional machining using lasers, ultrasonic, ion-beams or electrical discharge. However, these methods require lots of time, workpiece materials are limited, and such methods are only applicable to the machining of two-dimensional shapes. Therefore, mechanical machining methods are required for the manufacturing of micro parts with complex shapes. This paper presents an investigation on the characteristics for micro groove machining by using the ultrahigh-speed air turbine spindle, and verifies the properties of mechanical method in fabricating molds for micro barrier ribs. As a result, the optimal machining condition could be found from the investigation of surface roughness according to the kinds of burr shapes in the fabricating of iron mold by using micro endmill.

화력발전 플랜트의 터빈 블레이드(blade) 재료인 12Cr 합금강의 고속 열화 시편에 대한 레일리(Rayleigh) 표면탄성파의 산란과 속도의 주파수 의존특성을 액체/고체 경계 면에서 표면파의 발생기구에 의해 나타나는 후방복사 초음파 세기의 입사각 의존성으로 간접 평가하고 부식피로 특성과 비교 분석하였다. 후방복사 현상이 발생하는 입사각 폭은 부식온도와 반비례하였으며 이는 효과적 부식층의 두께 증가로 설명되었다. 이 프로파일의 폭은 피로시험에서 균열성장 관계식인 파리스(Paris) 법칙의 지수 m과 선형적으로 반비례하여 열화시편의 부식 피로 특성의 비파괴적 평가에 있어 후방복사된 초음파를 이용한 기술이 매우 유용함을 보여주었다. The corrosion-fatigue characteristics of the 12Cr steel, which is widely used in fossil power plants as a turbine blade material, are evaluated nondestructively by use of the Rayleigh surface wave. In this study, the frequency dependency of the Rayleigh surface wave is investigated indirectly by measuring the angular dependency of the backward radiation of the incident ultrasonic wave in the aged specimens, and then compared to the corrosion-fatigue characteristics. The width of the backward radiation profile decreases as the increase of the aging temperature, which seems to result from the increase of the effective degrading layer thickness. This parameter also shows an inversely proportionality to the exponent, m, in the Paris law which predicts the crack size increasement due to fatigue. The result observed in this study demonstrates high potential of the backward radiated ultrasound as a tool for the nondestructive evaluation of the corrosion-fatigue characteristics of the aged materials.

As unbanization and population have been increasing, cometerys have caused a lot of social problems. In order to improve these, a cemetery park with various functions like cemetery and park should be made. A cemetery park can provide neighboring people as well as cemetery users with spaces for relaxation and graves. Therefore the purpose of this study is to suggest basic directions for efficient policy which can change people's way of thinking about a propitious grave site and form new land culture. The conclusions are : First, in the aspect of system, laws related to burial and cemetery-grave size, and structures-should be changed in pace with people's consiousness and the rationalization of land. Second, in the aspect of administration, roads to cemetery parks, landscape and facilities should be prepared. And the plan should be made which neglected or unknown graves can be checked to be put in charnel. Besides by analyzing good and bad points of old cemetery, better ones should be made. It should take the department concerned and experts to manage the efficient policy for cemetery. Third, in the aspect of people's consciousness constant publicity activites about the efficient use of land will help to solve a sense of incompatibility caused by using excessive use of cemetery. Fourth, as this research shows, enough greenbelt and parking areas must be prepared with landscape, facilities and management improved.

Yongdong region is semi-mountainous area. The sea levels of Yongdong-gun is around 100∼300m, the annual average temperature is 11.5℃ and the annual average difference of temperature between day and night is 10∼15℃. Thus the weather conditions of Yongdong region was suitable for grape production especially in sweetening and coloring of grape during ripening season. To promote commodity attributes of Yongdong Grape it is needed to introduce grading, standardization, improving packing and using a trade-mark. To open and extend new market it is necessary activating shipping organization, selecting practicalize market supplying marketing information, advertising, and publicizing. There were three grape processing companies in Yongdong-Gun. They were mostly small sized and purchased and used only 877 M/T (2.9% of total production) of grapes as a raw materials. These grape processing companies produced very low added value because they sold there product as OEM, or at consumer market. Present grading and packing system which is managed by individual producer base is needed to introduce cooperative inspection system which units of grape shipping organization or regional cooperatives take part in inspection. Also introducing cooperative recording and accounting system would maximize internal economic effects of marketing. Future scope and function of cooperative grape farm organization of Youngdong-Gun would develop from partial cooperative organization which produce and pack grape by individual base but inspect, ship and trade by cooperative system to whole cooperative organization of which scope and function is expended to common brand of grape and Yongdong-gun level organization. Establishing information and publication's post in Yongdong-Gun building, constructing grape theme park and opening grape festival which is needed to attract tourist are needed to encourage and promote advertisement and publicity of Yongdong Grape.

Background: Invasive aspergillosis (IA) is associated with significant morbidity and mortality in patients with hematologic malignancies. We investigated the efficacy and safety of voriconazole (VCZ) when used as salvage therapy for IA in Korean adults with hematologic malignancies who had not responded to prior antifungal therapy. Materials and Methods: We retrospectively reviewed data, collected from January 2007 to October 2008, from patients with proven or probable cases of IA. All were probable IA cases, except for one proven case. All cases were refractory or intolerant to antifungal therapy prior to administration of VCZ. Efficacy and safety were assessed in patients treated with VCZ for more than 3 days and for more than one dose, respectively. A favorable response [complete (CR) or partial (PR)] was defined by significant improvement of all clinical symptoms, signs, and radiologic abnormalities. Results: Fifty patients who met the inclusion criteria were enrolled. There were 27 male and 23 female patients with mean age of 44.4 years (range, 15-65 years). Underlying diseases were acute leukemia (35 cases), chronic myelogenous leukemia (4 cases), myelodysplastic syndrome (3 cases), lymphoma (3 cases) and other hematologic diseases (5 cases). Twenty-two patients had received chemotherapy and 13 patients had undergone hematopoietic stem cell transplantation. The lung was the main infection site (94%) followed by the sinus (6%). Amphotericin B deoxycholate alone was the most frequent previous antifungal therapy. The mean duration of antifungal therapy prior to VCZ therapy was 13.9±8.8 days (2-44 days). The median duration of VCZ therapy was 19 days (interquartile range, 49 days). Sixteen patients (32.0%) showed favorable responses (CR:PR=8:8) at the end of VCZ therapy. The numbers of patients with stable disease, progression and death were, 6 (12%), 6 (12%) and 22 (44%) respectively. Most of those with unfavorable responses had relapsed underlying malignancies or refractory graft versus host diseases. Twelve patients developed drug-related adverse events but only one patient stopped VCZ treatment prematurely. Conclusions: VCZ demonstrated an acceptable level of toxicity in patients with hematologic malignancies but further studies are required to prove its efficacy as salvage therapy.

To find out the optimum fertilizer level for high yielding variety, Velox, experiment was conducted with 15 compositions of fertilizer levels at the experiment field of forage crop in Sunchon National University from Mar. 2000 to Aug. 2000. The effects of nitrogen fertilizer on plant growth were significant but increasing rate of application in potassium and phosphate fertilizers above 6 kg/a had negligible effects on plant growth. The optimum nitrogen application level of fertilizers turned out to be 16-6-6 kg/l0a of N-P2O5-K5O. Content of crude protein was highest and that of crude fiber such as NDF, ADF, cellulose and lignin were lowest at this rate of fertilizer application. Furthermore, IVDMD was high and dry matter yield were highest at the optimum raterate

Does free transplanted autologous cartilage grow? Until now many autors have published different results about the growth potential of cartilage. Some authors have produced in their study that transplanted cartilages were able to grow, but others showed contradicting results. In this study, authors obtained cartilages from young rabbits'ear, 10 by 10mm in size and divided them into two groups ; the first group was cartilages with perichondrium and the second group was cartilages stripped perichondrium. We transplanted both groups of cartilages in the posterior nuchal area of rabbits. Then numbers of specimens of each group were evaluated and compared for assessment of cartilage growth. After observaton for six months, we took the cartilages from the posterior nuchal area and examined the surface area, the thickness, and the weight and finally confirmed the growth potential of the cartilage by histologic study. The results are as follows : 1, The surface area, the thickness, and the width of the transplanted cartilages were increased significantly in gross specimens and their measured values were statistically significant and cartilages with perichondrium showed more growth than cartilages stripped perichondrium 2. In histologic studies, we observed increased surface activities with numerous proliferatng cells and found no abnormal features compared with normal cartilages. Cartilages with pericondrium were thicker than cartilages with stripped perichondrium
