RNA 정량검사는 혈중 바이러스 농도를 측정하는 검사로, 감염인의 투약과 치료에 필수적인 검사로써 감염인이라면 $3{\sim}6$개월 간격으로 정기적으로 받는 검사이다. 그동안 국가에서 시행해 왔던 RNA 정량검사가 2009년 7월 1일자로 민간 의료기관에서 시행된다. RNA 정량검사를 민간 의료기관에서 실시하게 됨에 따라 감염인의 진료비 부담이 증가하게 된다. 병원에 따라서는 감염인의 비급여 본인부담금을 고려하여 특진료를 가산하지 않는 병원도 있으나 이는 극히 일부 병원에 불과한 실정이다.

To understand the role of shelf sediment in phosphorus biogeochemical cycle, we carried out sequential sediment extraction (SEDEX) of P and porewater analysis on 14 core samples collected in the South Sea of Korea, SEDEX classified P-pools into 5 phases and results are grouped into two categories: reactive P (loosely sorbed-P and Fe bound-P) and refractory P (detrital inorganic-p, authigenic mineral-P and organic-P). Total P concentrations are decreased with sediment depth in all samples as a result of dissolution to porewater. Reactive P comprises about $20\~50\%$ of total P, and iron bound-P is the major form consisting $70\~80\%$ of reactive P-pool. Iron bound-P decreases sharply with depth. Depth profiles of dissolved P concentration in porewater show mirror image of iron bound-P, revealing the role of FeOOH as a regulator of reactive P supply to overlying water column. Authigenic mineral-P consists less than $5\%$ of total P, thus removal of reactive P by converting into refractory P seems inefficient in shelf sediment. This implies that continental shelf sediment sequesters P temporarily rather than permanently. Results show local variation. Nakdong estuary receiving large amount of terrigenous input shows the highest concentration of total P and reactive P. Here iron oxyhydroxides at the surface sediment control the water column flux of P from sediment. Although total P content at the surface is comparable (500$\~$600 ${\mu}g{\cdot}g^{-1}$) between the South Sea and East China Sea, the former contains more iron bound-P and less derital inorganic-P than the latter. Reasons for the difference seem due in part to particle texture, and to biological productivity which depends roughly on the distance from land.

Movie contents requiring multiple shootings in places need much man power and many equipments. It is more serious in the case of multiple simultaneous shootings. In the points of small broadcasting companies, it is more difficult to cope with the situation, but it is also an essential task for the variety of video contents. We propose an one-person movie production scheme based on an IP camera-based live webcasting system which makes multiple shootings in places possible. It consists of three main functions of (1) collecting multiple video streams sent from IP cameras installed in places, (2) properly distributing them to Internet, and (3) receiving and editing them including recording video. By using the proposed scheme, we can be able to remotely utilize a new framework of Single-Person/ Multiple-Camera which beyonds the conventional Single-Person/Single-Camera framework. It becomes possible to take multiple simultaneous shoots in places. We can get an advantage of saving man power and time for producing various movie contents.

The influence of stage of lactation on the moisture. total soilds, ash, calcium, phosphorus and Ca/P ratio of human milk was studied. A total number of 32 lactating mothers provided 101 samples collected at 4 consecutive stages of lactation : days o to 5 postpartum(colostrum); days 6 to 10 postpartum(transitional): days 25-35 postpartum(mature). and days 55-70 postpartum(mature). Moisture and total solids concentrations showed a little but significant difference at the 25-35 day stage as compared with those of colostrum and then remained stable, but ash levels decreased significantly with the elapse of lactation period. Calcium levels increased significantly from colostrum to transitional milk stage with a further less significant increase at mature stages. Between colostrum and transitional stages, phosphorus concentration showed a significant increase $(9.9\pm2.4$ vs $15.5\pm4.9$ mg/100 ml, p<0.001)but between the 25-35 day and the 55-70 day stage phosphorus values did not change significantly. Ca/P ratios for colostrum. transitional, the 25-35 day and the 55-70 day stages were 2.28, 1.76, 1.68 and 1.95, respectively. No significant relationship was found between ash. calcium, phosphorus or Ca/P ratio of milk and maternal parity. When modified milk formulas were reconstituted using the total solids of human mature milk as amount of the modified milk formula in 100 ml of infant feeding solution. ash, and Ca/P ratio were similar to those of human milk. However considerably higher concentrations of calcium and phosphorus exist in the reconstitution fluid than those observed in human milk.

Nutrients removal by water hyacinth, Eichhornia crassipes (Mart.) Solms from nutrient enriched waters and swinery wastewater were evaluated. The contents of nitrogen and phosphorus of dried water hyacinth increased from 1.4 to 3.3% and 0.21 to 0.80% when water hyacinth available N and P in the culture medium were increased from 0.7 to 5.0 mgN/1 and 0.06 o 1.5 mgP/l. respectively. Maximum N and P contents were found to be 4.1 and 0.90%, respectively. The significant relationship was observed between the standing crop of water hyacinth and the biomass yield per unit area and time. Biomass yield increased gradually until standing crop reached 15 kg wet wt./m$^2$, and then rapidly decreased. The high biomass yield of up to 0.5 kg/m$^2$/day was obtained in the range of 7 to 20 kg/m$^2$of standing crop. The potential removal rates of N and P by the water hyacinth during summer were found to be 2,250 to 2,710 mgN/m$^2$/day and 570 to 595 mgP/m$^2$/day, respectively, when 15 kg/m$^2$in standing crop and nutrient concentrations of culture medium were ranged from 1.24 to 6.2 mgP/1 and 3.2 to 32.5 mgN/1, respectively, Inorganic N and P concentrations of swinery wastewater were in the range of 82 to 121 mgN/1 and 22 to 79 mgP/1, respectively. Nitrogen and P removal rates of water hyacinth cultured in swinery wastewater were found to be in the ranges of 2,000 to 2,600 mgN/m$^2$/day and 157 to 254 mgP/m$^2$/day, respectively, at 10 times diluted water of swinery wastewater.

The purpose of this study was to investigate the effects of medical nutrition therapy(MNT) on plasma lipid levels of hyperlipidemic patients with apo E3 genotype according to Sasang Constitutions. From March to July, 2001, the 33 hyperlipidemic patients admitted to K University Medical Center were studied. The study subjects were classified according to their Sasang constitutions by QSCC II questionnaire which have been used at K University Oriental Medical Center. The anthropometric assessments, blood analysis, and apo E genetic typing were carried out. Nutrient intake was determined by food record method of food taken during two weekdays and one weekend. The MNT including the instruction for hypolipidemic and hypocholesterolemic diet (step l diet) was performed for 12 weeks. The results are as follow; (1) The mean age of hyperlipidemic patients was $49.91{\pm}8.48$ years. (2) The distributions of Sasang Constitution were 60.6% of Tae-eum, 21.2% of So-yang, and 18.2% of So-eum. The distributions of apo E genotype were 6.5% of apo E2/3, 78.8% of apo E 3/3, and 15.2% of apo E 3/4. (3) The nutrient consumption of the apo E3 subjects before the MNT showed lower calorie, iron, calcium, and vitamin B2 intakes than the RDAs for each nutrients with no significant differences among the constitutions. After 12-week of MNT, only the fat consumption was decreased in the Tae-eum group. The MNT did not change the pattern of food intake. (4) The plasma level of triglyceride, total cholesterol, and LDL-C were not changed after MNT in the three constitutional groups. The level of HDL-C was significantly increased significantly in Tae-eum and So-yang group and the level of homocystein was lowered in Tae-eum group after MNT. It could be concluded that the 12-weeks MNT with hypolipidemic and hypocholesterolemic diet did not change the level of total cholesterol, triglyceride, and LDL-C effectively regardless of Sasang constitutions even though the subjects' dietary intake was improved by MNT.

Using the Artificial Neural Network model and Binary Logistic Regression model, this study investigates influence factors on the quality of life in terms of housing environment during the COVID-19 in Seoul. The results show that the lower the satisfaction level of housing policy, the lower the quality of life in the employment field and the lower the quality of residential field. On the other hand, permanent workers and self-employed respondents have experienced improvement in residential quality during the pandemic. A limitation of this study is associated with disentangling the causal relationship using the 'black box' characteristics of ANN method.
