송서일,이보근,조영찬 동아대학교 공과대학부설 생산기술연구소 1997 生産技術硏究所硏究論文集 Vol.2 No.2

It is revealed that, as the use of automated manufacturing is increasing and the process inspection technology is improvements in industry for recently years, the data from mass production system is exhibited some degree of autocorrelation. The operation characteristics of traditional control charts developed under the assumption of independence may be adversely affected by the presence of serial correlation. Therefore, we try to explain a autocorrelated construction by being in contact with a time-series models, so called the Box-Jenkins forecast models, which has been proposed as a very good forecasting tool and allows to distinguish the variations resulted from a autocorrelation structure from one due to unusual but assignable causes. In this paper, autoregressive/moving average parameters in the use of Box-Jenkins forecast models is estimated, and a sensitivity analysis is given by comparing X control chart with CUSUM control chart for the variation of error or forecast residuals.

송영보,이치훈,나오수,이영돈 濟州大學校 海洋硏究所 2002 해양과환경연구소 연구논문집 Vol.26 No.-

1995년 9월부터 1996년 8월까지 제주대학교 해양과 환경연구소가 위치한 함덕연안 조간대에서 채집한 울타리고둥, M. labio의 생식주기를 조사하기 위하여 생식소숙도지수의 변화와 생식세포 형성과정을 조직학적방법으로 조사하였다. 1. 울타리고둥의 생식소는 패각내 나선상 육질부 하단에서 꼬리돌기까지 간장부의 표면에 위치 하였다. 생식소가 성숙하면 암컷은 짙은 녹색, 수컷은 유백색을 띠고, 방출 후에는 암컷은 연갈색, 수컷은 연황색을 나타내었다. 2. 생식소숙도지수(GSI)는 암컷과 수컷 모두 수온이 상승하는 4월부터 상승하기 시작하여 9월에 암컷 0.47, 수컷 0.42로 최고치를 보이고 이후 10월부터 급격히 감소하였다. 저수온기인 1월에 GSI는 암컷과 수컷 모두 0.07로 최저치를 보였다. 3. 생식소의 발달 단계는 분열증식기(3월∼4월), 성장기(4월∼7월), 성숙기(8월∼9월) 그리고 방출 및 회복기(10월∼1월)의 연속적인 주기로 구분 할 수 있고, 주산란 시기는 10월로 추정 된다. 4. 울타리고둥, M. labio은 자웅이체로서, 성비는 약 1:1이었다(P>0.05). Reproductive cycle of thick liped monodont. Mondonta labio was invetigated by the histological observation of gonads and the gonadosomatic index(GSI). The thick liped monodont were collected at the intertidal zone of Hamdeok in Jeju-do from September, 1995 to August, 1996. Gonad of them was located o the surface of the liver below the stomachal caecum posterior spiral meat part of the shell. GSI value began to increase from May(as water temperature increased) and reached it's maximum value in September both male and female which were 0.42 and 0.47, respectively. It began to decrease from October thereafter, maintaining relatively in low value from January to March. The reproductive cycle of this species could be classified into four successive developmental stage; multiplication stage(March to April), growing stage(April to July), mature stage(August to september), spent and recovery stage(October to January). The main spawning period of M. labio appeared in October. The top shell, M. labio appeared to be gonochorism, neither sex reversal nor hermaphroditism. The sex ratio was approximately 1.0 : 1.0(P>0.05).

송재영,김용일,박보영,정재영,최현구,정종태,이희봉 충남대학교 농업과학연구소 2004 농업과학연구 Vol.31 No.1

This study was carried out to identify the effects of seaweed extracts(GA14) on growth of two rice cultivars, Junambyo and Donganbyo. Seedling qualities of two cultivars were better in all items including heading dates at early stage treated at seedling plus 2-3 leaf stages than at single treatment of seedling. Ripening ratio of Junambyo in paddy field was increased 0.3% by seaweed extracts(GA14) treatment, but that of Donganbyo decreased 0.5%. 1,000 grain weight of Junambyo and Donanbyo by seaweed extracts(GA14) treatment was two to four grams higher and the yield of two cultivars was also higher by three to four percent. Appearance characters of two rice cultivars was high in head, while damaged, chalky and crack rate were low at seaweed extracts(GA14) treatment. Protein, moisture and amylose characteristics related to table quality of Junambyo were not different by seaweed extracts treatment, but table values was high in only treatment. Donganbyo was also similar to Junambyo, but table quality was slightly high at non-treatment.

The tumor suppressor gene p53, located on the short arm of chromosome 17, encodes for nuclear protein which regulates cell proliferation by inhibiting cells entering S-phase. Mutation in p53 gene are the most frequent genetic alteration found in human cancers to date. This study was examined mutant p53 gene mutation using PCR-SSCP method and mutant p53 oncoprotein expression using avidin biotin peroxidase complex method immunohistochemically, in 2 seborrheic keratosis, 3 basal cell carcinoma, 3 squamous cell carcinoma and 1 metaststic squamous cell carcinoma cases. With PCR-SSCP methods in exon 5 and 7, no genetic mutation of p53 gene was observed in 2 seborrheic keratosis, 3 basal cell carcinoma, 3 squamous cell carcinoma, and 1 metaststic squamous cell carcinoma cases. With immunohistochemical staining with ABC method, a case of squamous cell carcinoma developed on lower lip was positive but another were all negative. This result means that p53 gene mutation on skin tumor may develope in squamous cell carcinoma developed on sun exposed area and this mutation on squamous cell carcinoma can develope other exonal site except exon 5 and 7.

Papulonecrotic tuberculid is an eruption of necrotizing papules, particularly affecting the extremities and occurring in more or less symmetrical crops, and responding to antituberculosis therapy. Individual lesions heal with scarring. Histologically, vascular involvement is seen in early lesions. Late lesions are divided into two forms. In superficial forms, wedge shaped area of necrosis forms in epidermis and upper dermis. Epithelial and lymphoid cells gather around its periphery. In deep forms, with no epidermal change, granulomatous changes surrounded by well defined palisading histiocyte and lymphoid, epithelioid cells are seen. In mid-dermis and perivascular area, vessel shows vasculitis. In the first case, leukocytoclastic vasculitis and early granuloma formation were seen. In the second case, palisading granuloma formation was seen. In the third case, tuberculoid granuloma formation was seen. We report three cases of papulonecrotic tuberculid showing three different stages of histological finding, in individual cases.

Before 1984, Leptospirosis had been reported sporadically in middle inland of Korea as hemorrhagic pneumonia like disease, epidemic pulmonary hemorrhagic fever or epidemic pneumonitis since 1975. The epidemiologic characteristics of this disease were found out and the agent was isolated microbiologically after a large epidemic in 1984. Thereafter many consecutive studies for leptospirosis had been performed in the realm of epidemiology, microbiology and clinical field. But in order to appropriate control of Leptospirosis there are many problems such as organizing surveillance system for early diagnosis and treatment, identifying sero-group and serovar in each epidemic area and assessing vaccine efficacy. The objectives of this study was to find out easily applicable diagnostic methods to be used in a rural community surveillance system. Two diagnostic methods, passive hemagglutination(PHA) test and macroscopic agglutination test(maAT) were measured against their accuracies, sensitivity, specificity and predictive value of positive and negative. 301 sample sera from 270 human cases was collected through Leptospirossis surveillance system in a rural community during 1989-1992. Microscopic agglutination test(MAT) were used for confirmed diagnosis according to WHO guideline with 4 strains; Icterohemorrhagiae lai and Canicola canicola Hond Utrecht IV as standard strians and 6P-014-1 and YP-35-1 as strains isolated in Korea in 1986. The results are as follows. 1. 75(24.9%) among 301 sample sera and 49(18.1%) among 270 persons was serologically positive with MAT. 2. Agreement between PHA and MaAT was very low(k-coefficient≤0.252). 3. In PHA, specificity was very high(≥0.96) but sensitivity was very low(≤0.28). 4. In MaAT, specificity(≥0.73) was relatively lower than PHA but sensitivity (≥0.79) was significantly higher than PHA, especially false-positive rate case was absent in MAT's high antibody titer(above 1:640). It was concluded that MaAT method was a very useful diagnostic tool for early diagnosis of Leptospirosis in a rural community surveillance system, provided that confirmed diagnosis with MAT method be carried out in laboratory of medical school or research institute such as National Institute of Health or Provicial government Institute of Health and Environment.
