Cheese is a nutritious food with various balanced nutrients, such as proteins, peptides, amino acids, fats, fatty acids, vitamins and minerals. Domestic cheese varieties and quality need to be improved to prevent imported cheese. To develop those cheeses, search for previous works and research for new products are needed. In cheese ripening of hard cheese, such as Cheddar or Parmesan cheese, is ripened for 2 to 24 months at 2 to 16℃ to develop desired cheese flavor and body characteristics. Long time with low temperature to ripen the cheese requires high expenses. So accelerated cheese ripening is a good potential for saving in industry. Methods for acceleration of cheese ripening are temperature control, addition of bacteria or enzymes. To develop the functionality of cheese, addition of microencapsulated various probiotics and nutrients, such as iron, removal of cholesterol by crosslinked β-cyclodextrin, lowering blood cholesterol and serum glucose by nanopowdered functional materials et al. are necessary. Therefore, this review focused on the functionality of cheese, such as the acceleration of cheese ripening, microencapsulated probiotics and iron, and cholesterol removal.

본 연구에서는 고압처리(high pressure processing) 한 원유를 이용하여 발효유를 제조하고, 발효특성 및 저장 기간 물리 화학적 특성의 변화를 살펴보았다. 고압처리 한 원유를 이용하여 발효유 제조 시 발효 초반에 유산균이 급격히 증식됨을 확인하였으나, 발효 완료 후 총 유산균 수는 대조군과 크게 차이가 나지 않았다. 저장 기간 중 실험군과 대조군 모두 유산균 수가 서서히 감소하는 경향을 나타내었다. 또한 산도 및 pH는 각 군 모두 정상적인 발효유의 범위를 나타내었다. 각 군의 점도를 대조해 본 결과 대조군이 실험군보다 점도가 높게 나타났으나, syneresis는 450 MPa 처리군이 대조군보다 유의적으로 적게 발생한 것으로 나타났다(P<0.05). 따라서 적절한 압력을 이용한 원유의 고압처리는 발효유의 물성을 개선하는 데 효과가 있다고 할 수 있으며, 이 분야에 관한 연구가 좀 더 이루어져야 할 필요가 있다. This study was carried out to investigate the physicochemical and fermentation properties of yogurt made from high pressure processing (HPP) treated milk. Raw milk and commercial yogurt starter were used to make yogurt. Raw milk was HPP treated at 350 or 450 MPa (HPP 350 or 450) for 15 min or heat treated at 80°C for 10 min. The numbers of lactic acid bacteria of the HPP treated group (HPP yogurt) rapidly increased during 2∼4 h, whereas there was not significant difference from control (P<0.05). Titratable acidity of all samples increased, and pH decreased during storage from 0.99 to 1.24%, as well as from 4.59 to 4.20, respectively. It is confirmed that these values are in general ranges for yogurt. Control showed higher viscosity than HPP 350. Syneresis was significantly lower than that of the control (P<0.05). Based on the data obtained from the present study, HPP treatment was effective to enhance the quality of yogurt.

1979년부터 1987년까지의 서울대학교병원 치료방사선과에서 흉선암으로 근치목적의 방사선치료를 받은 21명을 대상으로 조사하였다. 전체환자의 3년생존율은 $80.5{\%}$, 3년 무병생존율은 $78.6{\%}$였다. 근무력증을 동반한 환자는 $43.5{\%}$였고 치료후 $40{\%}$ (4/10)에서 증상의 호전을 보였다. 증상의 유무에 따른 3년생존율을 비교하여보면 각각 $90{\%}$, $78.8{\%}$였으며 근무력증이 예후에 나쁜 영향을 주는 인자가 아님을 알 수 있었다. 방사선치료후 완전관해율은 절제술을 시행한 경우는 $100{\%}$(3/3)인 반면, 절제가 불가능한 경우는 $20{\%}$(3/15)였다. 완전관해율 및 부분관해율은($33{\%}$ vs $56{\%}$) $89{\%}$였고 이에 따른 3년생존율은 각각 $89.8{\%},\;81.7{\%}$로 통계학적으로 유의한 차이는 보이지 않았다. 수술정도에 따른 치료실패율을 비교하여보면 절제가 가능한 환자에서는 치료실패가 없었으나, 절제가 불가능하였던 환자 15명중 4명에서 국소실패, 1명이 골전이 소견을 보였다. 국소치료실패가 대부분으로 원격전이율은 낮은 양상을 보였다. Twenty one patients of malignant thymoma treated with curative aim at the Department of Therapeutic Radiology of Seoul National University Hospital from 1979 to 1987 were analysed retrospectively. The 3 year overall and relapse free survival rate was $80.5\%\;and\;78.6$, respectively. Myasthenia gravis (MG) was seen in $43.5\%$ at presentation and disappeared in $40\%$ (4/10) after radiotherapy with or without operation. The 3 year cumulative survival rate with and without MG was $90\;and\;78.8\%$, respectively. We could consider that MG was no longer adverse prognostic factor. The complete response rate after partial resection was $100\%$ (3/3), and that after biopsy was $20\%$(3/15). The overall local control rate including complete and partial response rate ($33\;vs\;56\%$)was$89\%$ and the 3 year actuarial survival rate by the response rate was $88.9\%\;and\;81.7\%$, respectively. There was no statistically significant survival difference between two groups. The crude rate of relapse at 3 years was $23.8\%$ (5/21), and $80\%$ (4/5) were locoregional failures. All failures were observed in biopsy only group, while no failure was observed in resected group. The major pattern of the treatment failure was the locoregional failure and the distant metastases was rarely observed.

This study was to review the classification, detection and control of bacteriophage in fermented dairy products. Bacteriophage has lytic and/or lysogenic life cycles. Epidemiologically speaking, detected major phages are c2, 936 and p335. Among them p335 has been the largest concern in dairy industry. Traditionally, various analytical technologies, such as spot, starter activity, indicator test, ATP measurement and conductimetric analysis, have been used for the phage detection. In recent years, advanced methods such as flow cytometric method, petrifilm, enzyme linked immunosorbent assay (ELISA) and multiflex PCR diagnostic kit have been deveoloped. The phage contamination has been controlled by using heat, high-pressure treatment, and the combinations of heat and pressure, and/or chemical. Also some starter cultures with phage-resistant character have been developed to minimize the concentration of phages in dairy product. Bacteriophage inhibition media such as calcium medium was also mentioned. To prevent the contamination of bacteriophage in dairy industry, further researches on the detection and control of phage, and phage resistant starters are necessary in the future.

EL (electro-luminescent) device as a light source has an advantage in embodying large area with great flexibility. On nickel foil as an electrode and backplane, we demonstrated a white EL flexible light source with blue phosphor layer combined with color change layer. A correlation between color change layer and color coordination was analyzed by Gaussian method, and then the color coordinate was controlled near to (0.33, 0.33) of pure white light.
