Auther examined rectal swabs and mesentric lymphnodes of 65 swines which were slaughtered as healty animal at Taegu Slaughter House during the summer of 1959, and rectal swabs of 58 normal swines which were fed on garbage in the surrounding area of Taegu City in August, 1960. From the 65 mesentric lymphnodes, 4 strains (6.1%) of Salmonella were isolated, and lone strain (0.8%) was isolated from the 122 rectal swabs. The following types were identified. Sal. typhi-murium……3 Sal. oxford……1 E group organism (not named)……1

For the purpose of investigation on the pathogenecity of proteus, first of all, author examined biochemical property and toxigenecity for the isolated proteus. The summarized results were as follows. 1.In the isolation percentage of each animal, the dog was the maximum, 48.6 percent. 2,Biochemical properties of the isolated bacteria were equal to the Proteus which has been described so far, and the classification to depend on Indole production and Maltose fermentation was that approximately 70 percent were Proteus vugaris and Proteus mirabilis, but the rest 300 percent were the intermediate type which is not classified by the above biochemical property. 3.In toxigenecity test 32,4 percent among the isolated bacteria were positively to three kinds of toxigenecities-Hemolysis, the Sperm agglutination and the productivity of necrotictoxin.
動物由來 Proteae에 關한 硏究 (2) : 分離菌의 血淸學的 性狀에 對하여 Serological properties of the isolated proteus strains
趙漢喆 慶北大學校 1964 論文集 Vol.8 No.-
The results of serological investigation of the isolated 34 strains were as follows; 1. The majority of the strains was specific in their serological characeristics. 2. In appeared that the cross agglutinated strains were the identical strains. 3. Strain 25 failed to absorbe the agglutinines of the cross-agglutination strains, and also the agglutinine of this strain was not absorbed by the other cross-agglutinating strains. 4. No relationship was observed among the serological properites, biological properties and toxigenecities of the isolated proteus strains.

The South Korean defense industry is facing difficulties in ensuring its economy of scale. This is mainly because of the low demand compared to the supply. Such imbalance is on account of the unique nature of defense products, whose sole consumers are governments. Therefore, defense companies should expand their defense product sales through active PR (public relations) activities, including exhibitions, weapon systems demonstrations, and gathering information on the global defense industry. The results of this study show a positive correlation between the advertising cost and the management performance (sales and exports) of defense companies. In conclusion, defense companies can improve their management performance through active PR activities for the export of defense products.

Purpose: Few studies have reported postdiagnosis differences in distress and quality of life (QOL) for breast cancer (BC) survivors. Here we investigated the differences in distress and QOL for BC survivors in Korea, during follow-up. Methods: Completed questionnaires were collected from 179 BC survivors in 2013. Functional Assessment of Cancer Therapy-Breast was administered to measure the distress and Distress Thermometer and Problem List was administered to measure the QOL. Results: The mean QOL score was 96.69 (standard deviation, ±20.33). Seventy-nine patients (44.1%) with distress-test scores >4 were assigned to the severe distress group. The patient group with higher family income had high QOL score (p=0.008). In addition, QOL scores were significantly higher in patients who lived longer after diagnosis (p=0.016). Patients at high TNM stage had low QOL scores (p=0.006). Furthermore, older patients tended to have high distress scores (p=0.028). Based on duration of the postdiagnosis period, we divided the patients into two groups. Seventy patients had a postdiagnosis period <2 years; 109 patients, postdiagnosis period ≥2 years. Distress score of the under-2-year group (4.26±2.73) was significantly higher (p=0.044) than that of the longer-than-2-year group (3.47±2.42). Conclusion: BC survivors showed improvement in physical well-being, emotional well-being, and functional well-being domain of QOL over time. However, social well-being and BC subscale score were only slightly improved over time. It is possible that cancer patients’ supporting programs are focused on the recently diagnosed patients or those currently undergoing treatment. Therefore, more support should be made available to long-term BC survivors.
Post-CMP Cleaning에서 PVA 브러시 오염이 세정 효율에 미치는 영향

PVA (polyvinyl alcohol) brush cleaning method is a typical cleaning method for semiconductor cleaning process especially post-CMP cleaning. PVA brush contacts with the wafer surface and abrasive particle, generating the contact rotational torque of the brush, which is the removal mechanism. The brush rotational torque can overcome theoretically the adhesion force generated between the abrasive particle and wafer by zeta potential. However, after CMP (chemical mechanical polishing) process, many particles remained on the wafer because the brush was contaminated in previous post-CMP cleaning step. The abrasive particle on the brush redeposits to the wafer. The level of the brush contamination increased according to the cleaning run time. After cleaning the brush, the level of wafer contamination dramatically decreased. Therefore, the brush cleanliness effect on the cleaning performance and it is important for the brush to be maintained clearly.

The purpose of this study was to propose the design procedure of damped structure with friction damper for existing structure using inelastic displacement ratio. The target displacement of damped structure was determined based on seismic performance of existing structure and inelastic displacement ratio equation was used to predict the displacement of damped structure. This study conducted nonlinear response history analysis to verify the validity of design procedure using 80 earthquake ground motion. Based on the analysis results, the proposed procedure estimate well the displacement of damped structure.
