This study is intended to determine the optimum marketing time for grain products; rice and barley. The farmer has been faced apparently uncertainty caused by weather variation, price fluctuation and technological changes. Hence, one of the most important functions of individual farmer is to set up an optimum strategy for marketing time for the products they produce. Moreover, nonsystematic price variation over season is found especially in the case of grain products, in the short run are affected by the time and amount of grain import, price policy, expectation of the coming products, and so on. Thus, this study is decided to provide farmers as well as grain dealers with some information about the optimum marketing time which secures a maximum profit as greatly as possible, when price uncertainty has been taken into account, under assumption of several storage cost levels including the interest, risk, and the like. In other words, the game theory models have been applied to the monthly time series data of rice and barley prices for this objective. All price series are expressed in 1965 constant price, and are converted into November and July present price for rice and barley, respectively, when the storage costs have been considered. The results can be summaried as follows; 1. Rice marketing strategy a) Maximin criterion Interest rate Strategy selected (%) Single strategy Mixed strategy 0 Sell in Aug.

These results are suggest that the governments purchasing policy is effective in the sense that price is comparatively equalized to season for rice. However, barley puchasing policy seems to weak to equalized the price level over season thus far. Moreover, rice price control policy by government caused a destruction of marketing channel which is function of merchant under the society of capitalism. As mentioned above, it would be too sweeping to say that the results are always proper to every individual farm, because selection of the strategy for a farmer will likely depend on his psychological make-up.

본 연구는 수문학적으로 중·소유역에 해당되는 농촌용수구역에 적용 가능한 홍수량추정방법을 구명하여 재해방지와 효율적 관리에 기여키 위하여 수행되었다. 이를 위해 기존의 각종 홍수량 추정방법 중 선형유출계산법인 각종 단위유량도법과 비선형 유출계산법인 탱크모형을 이용하여 연구대상지역인 밀부 및 밀단 지역의 홍수량을 추정하고 그 결과를 실측자료와 비교하여 그 오차를 비교, 검토하여 다음과 같은 결론을 얻었다. 관측된 홍수량의 첨두 홍수량은 밀부 지구가 35.3~165.1 ㎡/s 이었고, 밀단 지구는 98.3~192.3㎡/s이었다. 첨두 발생시각은 밀부 지구가 11~23h, 밀단 지구가 7~15h이었으며, 유출률은 밀 부 지구가 61.8~64.3%, 밀단 지구는 66.7~82.7%이었다. 첨두유량에 대한 실측치와 추정치 간의 상대오차는 밀부 지구의 경운 탱크모형이 17.7%로서 가장 낮았고, SCS방법은 243.2%로서 가장 컸다. 밀단 지구의 경우는 탱크모형이 14.2%로 가장 낮았고 SCS방법이 104.3%로서 가장 높았다. 두 지구 모두 탱크모형으로 추정한 첨두 유량이 실측치에 가장 가까웠다. 그리고 첨두 유량 발생시각에 대한 추정 상대오차는 밀부 지구의 경우 실측 단위유량도가 8.8%로 가장 낮았고, SCS방법이 47.1%로서 가장 높았다. 밀단 지구의 경우 역시 실측단위도가 12.9%로 가장 낮았고, SCS가 16.1%로 가장 높았다. 두 지구 모두 실측단위유량 도법으로 추정한 첨두 유량발생 시각이 실측치에 가장 가까웠다 기저시간에 대한 추정 상대오차는 밀부 지구의 경우 실측 단위유량도가 2.4%로 가장 낮았고, SCS방법이 74.9%로서 가장 높았다. 밀단 지구의 경 우 역시 실측단위도가 20.8%로 가장 낮았고, SCS가 73.5%로 가장 높았다. 두 지구 모두 실측단위유량도 법으로 추정한 첨두 유량 발생시각이 실측치에 가장 가까웠다. 또 수문곡선 전체에 대한 실측치와 추정치 간의 상대오차는 탱크모형이 20.5%로 가장 낮고 SCS는 65.8%로서 가장 높았으며, 밀단 지구는 탱크모형 이 14.5%로 가장 낮고, SCS방법이 36.5%로서 가장 높았다. 두 지구 모두 탱크모형에 의해 추정한 수문곡 선이 실측치에 가까웠다. This study was carried out to give field engineers some references in selecting an appropriate flood runoff model for agricultural water sectors. Among various flood runoff models; unit hydrograph method, synthetic unit hydrograph methods such as Snyder method and SCS method as the linear runoff analysis model, and the tank model as the non-linear runoff analysis model were applied to study areas. The estimated floods by selected models were compared to observed floods, and then relative errors were calculated. The Tank model showed the lowest relative error by 14.5%, and SCS Model showed the highest value by 36.5% in Mildan. It was also resulted that the Tank model showed the lowest relative error in Milbu by 20.5%, while the SCS Model showed the highest value by 65.8%, however, the number of observed floods were not enough to attain concrete conclusion. So, direct adaptation of this result should be carefully considered due to the limited number of analysed floods.

The relation between tide level and ground water level in reclaimed land is one of important imformations to make the successful agriculture in reclaimed land and water resources development. To clarify this relationship, an investigation was made at the newly reclaimed land located in Gyeong-nam province. Obtained results were as follows: 1. The fluctuation of tide level affected significantly (r=0.468*∼0.670**) the ground water level variation in reclaimed land. 2. The nearer to shore line, the greater the effect of tidal fluctuation on ground water level. It was found that no significant effect of tidal fluctuation on ground water level existed beyond the range of 2km from shore line. 3. The average ground water level during the rising interval of tidal curve was higher than the average ground water level during the falling interval of tidal curve. 4. The magnitude of ground water level variation curve was one half of the magnitude of tidal curve.

IdMapper: A Java Application for ID Mapping across Multiple Cross-referencing Providers

Lee, Hoo-Keun,Kim, Hyeon-Jin,Yu, Ung-Sik Korea Genome Organization 2009 Genomics & informatics Vol.7 No.4

We developed an identifier mapping application for bioinformatics research in Java programming language. It is easy to use and provides many usability functionalities that are expected as essentials for a professional application. It supports three widely used mapping services and can convert many ids from one source database into many target databases at once. Id mapping across service providers is possible by remapping the resultant ids. Because it adheres to the NetBeans platform architecture, it can be incorporated into other NetBeans platform applications as an id mapping provider without adaption or modification.

Percutaneous needle biopsy is the most reliable nonoperative method of obtaining the definitive diagnosis of peripheral pulmonary lesion. Needle aspiration combined with cytologic examination is being used with increasing frequency in the diagnosis of pulmonary nodules and masses. Diagnostic needle aspiration of 59 localized pulmonary lesions was performed with 20 and 22 gauge needles between the beginning of November 1983 and the end of August 1986 at the Department of Internal Medicine of Hanyang University Hospital. Cough was the most common chief complaint. Next in order were chest pain, dyspnea, no symptoms, blood tinged sputum, production of mucus, generalized weakness. hoarseness, weight loss, and fever. The obtainability of the tissue was 91.5%, and diagnostic accuracy was 84.7%. Complications of percutaneous needle lung aspiration were: pneumothorax in 5 cases (8.5%), all of which were not required chest tube evacuation; minor hemoptsis ($lt;50ml) in 2 (3.4%), and hemnthorax in 1 (1.7%). We think that needle biopsy represents a minor, inexpensive and safe procedure, which-with a simple technique-permits a direct approach to all kinds of localized lung lesion with a high degree of accuracy.

pncA Mutations in the Specimens from Extrapulmonary Tuberculosis

Lee, Jae-Chun,Yun, Yeo-Jun,Kqueen, Cheah-Yoke,Lee, Jong-Hoo,Kim, Hee-Youn,Kim, Young-Ree,Kook, Yoon-Hoh,Lee, Keun-Hwa The Korean Academy of Tuberculosis and Respiratory 2012 Tuberculosis and Respiratory Diseases Vol.72 No.6

Background: Pyrazinamide (PZA) is an effective antitubercular drug that becomes toxic to Mycobacterium tuberculosis when converted to pyrazinoic acid by pyrazinamidase (PZase), encoded by mycobacterial pncA. A strong association was noted between the loss of PZase activity and PZA resistance. The causative organisms in extrapulmonary tuberculosis are rarely cultured and isolated. To detect pncA mutations in specimens from extrapulmonary tuberculosis as confirmative diagnosis of mycobacterial infection and alternative susceptibility test to PZA. Methods: Specimens were collected from clinically proven extrapulmonary tuberculosis. pncA was sequenced and compared with wild-type pncA. Results: pncA from 30 specimens from 23 donors were successfully amplified (56.6% in specimens, 59% in donors). Six mutations in pncA were detected (20.0% in amplified specimens, 26.1% in specimen donors) at nucleotide positions of 169, 248 and 419. The mutation at position 169 results in substitution of aspartic acid for histidine, a possible allelic variation of M. bovis that have intrinsic PZA resistance. The mutation at position 248 changes proline into arginine and that at position 419, arginine into histidine. Conclusion: DNA-based diagnosis using pncA may be simultaneously useful for the early diagnosis of mycobacterial infection and the rapid susceptibility to PZA in extrapulmonary tuberculosis. A potential implication of pncA allelic variation at 169 might be suggested as a rapid diagnostic test for M. bovis infection or Bacille Calmette-Gu$\acute{e}$rin (BCG) reactivation.

N/A Since the first report of clinical tsutsugamushi disease in Chinhae by Lee in 1986, the disease is now known to be a not uncommon infectious disease in many districts of Korea. In 1987, many cases of the disease were found in Ulsan, Ulchu and other locations in this vicinity. 1) In Dong Kang Hospital, 27 patients with tsutsugamushi disease were treated in October and November of 1987. Of 27 patients, 20 were serologically confirmed and the remainder were clinically documented. Another approximately 20 cases, which had been treated in several local clinics in Ulsan city, were discovered during a survey conducted by the Ulsan branch of the Korean Association of Internal Medicine. Thus, we presume that more than 50 cases of tustusgamushi disease might have developed in Ulsan, Ulchu and the surrounding areas in 1987, 2) The age of the 27 patients ranged from 19 to 74 years with the peak incidence occurring in the sixth decade. Of the 27 patients, 14 were male and 13 were female, which indicates that there was no sexual preponderance. Also 16 patients had their residence in Ulsan city, 8 in Ulchu Gun and 3 in Woelsung Gun. 3) Fever with chills(100%), myalgia (89%) and headache (859o) were the most common prominent symptoms and were frequently accompanied by gastrointestinal symptoms such as nausea, vomiting, anorexia. Important physical findings included skin rash (81%), conjunctival injection (56%), eschar (48%), lymphadenopathy (26%) and hepatosplenomegaly (48%). 4) According to laboratory tests, anemia and leukoeytosis were found in 48% and 16% of the patients respectively. Albuminuria was found in 11% of patients, hematuria in 22% and pyruia in 41%, 1ncreased FDP and decreased fibrinogen were seen in 74% and 37% of the patients respectively. 5) The chloramphenicol and tetracycline regimens were very effective in radpidly producing an afebrile state in all patients. However, in spite of chemotherapy a 74 year old patient, who had moderately advanced pulmonary tuberculosis and chronic obstructive lung disease, died due to respiratory failure.
