The drinking water in the apartment is stored in reservior tank and thereafter supplied each household. In case the drinking water is stored too long or insanitary, tap water might change in quality. This study was carried out to evaluate the physico-chemical and microbiological conditions of 36 samples of tap water of apartments compared to 18 samples of tap water of independence houses in Taegu City from May to October, 1987. Main findings are summarized as follows : PH values were within normal range in all samples. Samples less than 0.2ppm in residual chlorine accounted for 16.7% in the appartment and 5.6% in the independence house. Nitrite nitrogen was detected 2.8% of apartment samples only. Among the total of 54 samples, 11.1% of the apartment and independence samples were over the normal value in standard plate count. Samples more than 1.8 of most probable number(MPN) accounted for 27.8% in the apartment and 33.3% in the independence house. In result of test for residual chlorine, nitrite nitrogen, standard plate count, and MPN, the proportion of the samples revealed inappropriated in respect of drinking water standards. In case of all sorts of tests was 2.7% in apartment and nothing in independence houses, in case of 3 sorts of tests was 2.7% in apartment and 5.6% in independence houses, in case of 2 sorts of tests was 8.3% in apartment and 5.6% in independence houses, and in case of only 1 test was 25.0% in apartment and 22.2% in independence houses. Correlation between residual chlorine and standard plate count, and between standard plate count and MPN were observed. It was found that the more years since construction of apartment were, the worse tap water was in quality.
In Count case, the owners claimed from the charterers the amount of their loss resulting from the delay to the Count caused by the blockage of the channel due to stranding of the Pongola on the ground that this loss resulted from breach by the charterers of the safe port provisions. The Claim was referred to arbitration and dealt with on written submission. In a reasoned award, the arbitrators upheld the owners' claim. The charterers seek an order reversing the award or remitting it to the arbitrators for further consideration : (1) That the tribunal was wrong to find that the port of Beira was unsafe and that in consequence the charterers were liable to the owners in damages for detention. (2) That the tribunal was wrong to find that the port was unsafe in the abstract by reference to the fact that two other vessels had grounded there. (3) Having held that the Count was delayed for a little over four days by the fact that, after the charterers had nominated the port, the Pongola had grounded in the access channel, the tribunal should have held that the port was not prospectively unsafe. On the that the grounding the Pongola was caused by the characteristics which made the port an unsafe port to nominate for the Count. The court was held that it was not an independent event which broke the chain of causation between the breach of contract and the owner's loss. For those reasons, the court was upheld the arbitrator's award.
This study was carried out to compare lactic acid bacteria count of liquid type yogurts with various experimental conditions during shelf-life period. The conditions were media(BCP and Elliker agar), incubation conditions(aerobic and anaerobic), dilution waters(saline and phosphate buffer) and dilution methods(10 and 100 times). All of the samples were incubated at $37^{\circ}C$ for 72 hrs. In the case of counting L. acidophilus as a yogurt starter culture, there were differences on dilution waters and incubation conditions, but were no difference on media and dilution methods. In the case of counting L jugurti and mixed strain with L. acidophilus and L. casei, there were differences on media, incubation conditions and dilution waters, but was no difference on dilution methods. For L. casei in the yogurt, media and dilution methods were shown slightly different viable cell count but incubation conditions were not shown difference. In the case of counting L. bulgaricus, there were differences on media, incubation conditions and dilution methods, but was no difference on dilution waters. Therefore, the measurment of lactic acid bacteria count may be effective if preferred experimental conditions are selected for different types of strain.
To find out the differences in medical practice according to the environment of patient care and managerial situation of the medical care institutions, normal spontaneous vaginal delivery and acute appendicitis were selected, which is suitable for comparison because of their high comparability. A total of 473 cases of normal spontaneous vaginal delivery and 408 cases of acute appendicitis was sampled from the claims to Korea Medical Insurance Cooperations during January to June 1984. Complicated cases were excluded from population and sampling was restricted from 40 to 60 percentile for total charges by the type of medical care facility in order to rule out the influence originating from case mix. Important items representing type and quantity of medical care service were compared by type of facility. Major findings are as follows : 1. University hospital shows the highest in charges per case and decrease in order of general hospital, and clinic. 2. In case of normal spontaneous vaginal delivery, average length of stay shows statistically significant difference by type of facility. 3. Charge amount for each service item affected by practice pattern shows statistically significant difference mostly by type of facility. It is suggested that medical practice pattern is different by type of facility for medical services. 4. Difference in total medical expenditure by type of facility is affected more with charges for materials, consumables and drugs than with fee for service activity. 5. In administering drugs to patients, hospital and clinic show higher injection rate than university and general hospital. 6. Clinical Laboratory tests were common in order of uninalysis, hemoglobin, hematocrit, white blood cell count, urine microscopic examination in cases of normal spontaneous vaginal delivery; white blood cell count, urinalysis, hemoglobin, hematocrit, urine microscopic examination, white blood cell differential count, in cases of acute appendicitis. 7. The result for Laboratory test and Radiologic study shows extreme difference by type of facility. Test rate is lowest in clinic and increase hospital, general hospital, and university hospital in order, both in type and frequency.
Purpose: Quantitative analysis through count measurement in nuclear medicine planar images is limited by analysis techniques that are useful for obtaining various clinical information or by organ overlap or artifacts in actual clinical practice. On the other hand, the use of SPECT tomography images is quantitative analysis using volume rather than planar, which is not only free from problems such as projection overlap, but also has excellent quantitative accuracy. In the use of developing SPECT quantitative analysis technology, this study aims to compare the accuracy of quantitative analysis between ROI of the conventional planar images and VOI of the SPECT tomographic images in evaluating the count change happened by the volume change of the source. Materials and Methods: A 99mTcO4- source(200.17 MBq) was filled with sterilized water in the syringe to create a phantom with an inner diameter volume of 60 cc, and a planar image and a SPECT image were obtained by reducing the volume by 15 cc (25%) respectively. ROI and VOI(threshold: 1~45%, 5% interval) were set for each image obtained to estimate true count and measure the total count, and compared with the preseted volumetric change rate(%). Results: When volume changes of 25%, 50%, and 75% occurred in the initial volume of 60 cc(100%) of the phantom, the average count changes of the measured planar image were 26.8%, 53.2%, 77.5%, and the average count changes of the SPECT image were 24.4%, 50.9%, and 76.8%. In this case, the VOI size(cm3) set showed an average change rate of 25.4%, 51.1%, and 76.6%. The highest threshold value for the accuracy of radioactive concentration by VOI size (average error -1.03%) was 35%, and the VOI size of the same threshold had an error of -17.1% on average compared to the actual volume. Conclusion: On average, the count-based volumetric change rate in nuclear medicine images was able to track changes more accurately using VOI than ROI, but there was no significant difference with relatively similar value. However, the accuracy of radioactive concentration according to individual VOI sizes did not match, but it is considered that a relatively accurate quantitative analysis can be expected when the size of VOI is set smaller than the actual volume.

For measuring general bacterial count and Escherichia coli count, the standard plate count was used to conduct a test on 113 cases of pork carcass surfaces from slaughterhouses in Incheon area from January to February 2003. And Salmonella spp, Staphylococcus aureus and Listeria monocytogenes was used to conduct a test on 68 cases of pork carcass surfaces and 76 cases of feces, that is to say, a total of 144 cases. The results were obtained as follows: In the case of general bacterial count, 29 cases(25.7%) were in the range of 100∼999 and 62 cases(54.9%) were in the range of 1,000∼9,999 and 22 cases(19.4%) were in the range of 10,000∼99,999. Meanwhile as regards E coli count, 22 cases(19.4%) were in the range of 1∼9 and 69 cases(61.2%) were in the range of 10∼99 and 22 cases(19.4%) were in the range of 100∼999. On 68 cases of pork carcass surfaces, 7 strains(10.2%) of Salmonella spp, and 12 strains(17.6%) of S aureus were detected and 27 strains(39.7%) of L monocytogenes, respectively. As for the detected Salmonella spp, 6 strains of the B group, 3 strains of S enterica subsp salame and 2 strains of S typhimurium were detected, respectively. On 76 cases of feces, 14 strains(18.4%) of Salmonella spp, and 15 strains(19.7%) of L monocytogenes and 14 strains(18.4%) of S aureus were detected respectively. As for the detected Salmonella spp, 6 strains of the B group, 4 strains of S derby and 8 strains of the C group, 5 strains of S rissen were detected, respectively. All of 42 strains of L monocytogenes were type 1. As a result of conducting a toxin test on the detected S aureus, all of 26 strains were found to be non-toxin.

This study was done to investigate the effects of the incorporation of Achyranthes japonica extracts (AJE) in diet on the production parameters of growing pigs. Exp 1: Total, 105 crossbred pigs (average body weight: 24.47 ± 2.46 kg) were used in a 6-week feeding trial. Pigs (seven replicates, five pigs per pen) were allotted randomly to three treatments. Dietary treatments: CON (basal diet); basal diet with 0.025% AJE, and basal diet + 0.050% AJE). Growth performance, nutrient digestibility, fecal microbial count, and fecal noxious gas were assessed in this study. Average daily gain (ADG), average daily feed intake (ADFI), and gain to feed ratio (G:F) were not affected by the addition of up to 0.05% AJE. In the case of apparent total tract digestibility (ATTD), dry matter (DM), nitrogen (N), and digestible energy (DE) were not changed in 3rd and 6th weeks of the feeding trial through the addition of AJE up to 0.05% in the growing pig diet. In microbial count, Lactobacillus and Escherichia coli count at 3rd and 6th week was similar in all the treatment diets. The inclusion of AJE at levels up to 0.05% in growing pig diet had no effect on the production of NH3, H2S, acetic acid, and CO2 in the feces. After ending the Exp 1, a total of nine pigs were divided into three treatment groups. Treatment diets were included, TRT1, basal diet + powder quercetin 30 g; TRT2, basal diet + powder quercetin 150 g; TRT3, basal diet + powder quercetin 300g. Rate of absorption in blood was increased with the higher dose of quercetin. The results suggested incorporation of AJE up to 0.05% has no significant effect on ADG, ADFI, and G:F, as well as DM, N, and DE digestibility, fecal microbial count, and fecal noxious gas emission in growing pigs, even though no negative effect was found.

Current mobile communication system is in the mid-process of conversion from 4G LTE to 5G network. According to the generalization of mobile communication services, personal information such as user's identifiers and location information is transmitted through a mobile communication network. The importance of security technology is growing according to the characteristics of wireless mobile communication networks, the use of wireless shared channels is inevitable, and security technology cannot be applied to all network system elements in order to satisfy the bandwidth and speed requirements. In particular, for security threat analysis, researches are being conducted on various attack types and vulnerability analysis through rogue base stations or attacker UE to make user services impossible in the case of 5G networks. In this paper, we established a 5G network testbed using open sources. And we analyzed three security vulnerabilities related to NAS COUNT and confirmed the validity of two vulnerabilities based on the testbed or analyzing the 3GPP standard.
