This study was performed to examine the effects of Dan Jeon Breathing on stress, sleep disturbance and self-esteem of hemodialysis patients. This study used the nonequivalent control group pretest-posttest design. Before applying the Dan Jeon Breathing program, the patients were divided into the experimental group and the control group, respectively, and were requested to report their self-ratings to measure their stress, sleep disturbance and self-esteem. The Dan Jeon Breathing program was given to experimental groups for 60 minutes a day and 2 times a week for 12 weeks. The data collected from the program were analyzed by means of ${\chi}^2$ test, Fisher's exact probability test, Shapiro-Wilk and t-test. The analyses revealed that the stress(t=-2.95, p=.006) and sleep disturbance(t=-2.13, p=.041) levels of the experimental group decreased after Dan Jeon Breathing compared to those of the control group. The difference in self-esteem(t=2.44, p=.020) level was statistically significant. From the above results, it was verified that Dan Jeon Breathing could be used as nursing intervention for hemodialysis patients to mitigate their stress, sleep disturbance and to improve their self-esteem.

This study analyzed the management index, debt ratio, and business performance of livestock agricultural farming corporations since the Korea international financial reporting standards (K-IFRS) was introduced in 2011. In addition, this study was based on credible accounting reports by the financial supervisory service's DART (data analysis, retrieval and transfer) system. First, after analyzing the key management index, the results showed that the current ratio, debt ratio, and current liabilities ratio decreased and the ratio of the owners increased on the safety index. Regarding the profitability index, the ROA (return on total assets), ROE (return on equity), and ROS (return on sales) increased slightly in 2014 compared to 2013. The overall growth and external growth on the growth index have not increased. Second, an analysis of the debt ratio and business performance, the debt ratio has a negative effect on the ROA and ROS. These results show that the use of debt of livestock agricultural farming corporations contributes to the external growth but it has a negative effect on business performance. These results show that management should consider solutions for the increase in sales to achieve cost reductions. In addition, the debt ratio should be reduced and solutions for an increase in revenue are needed to reduce management expenses, such as propagation of technical development.

Objectives : Gliomatosis cerebri is an uncommon primary brain tumor characterized by diffuse neoplastic proliferation of glial cells, with the preservation of the underlying cytoarchitecture. The aim of this study is to evaluate clinical features, outcome of surgical treatment and adjuvant therapy of gliomatosis cerebri. Methods : Between Jan. 1990 and Dec. 2000, 12 patients were diagnosed with gliomatosis cerebri based on characteristic radiological and histological findings. The patients' age ranged from 18 to 77(mean 44) years and the male to female ratio was 7 : 5. Nine patients underwent decompressive surgery and three, biopsy only. Postoperative radiation therapy was given in all cases except three. In addition to radiation therapy, four patients received chemotherapy. The mean duration of follow-up period was 18.8 months. Results : The most common presenting symptom were seizure and motor weakness. The mean duration of symptom was 5.9 months. There was 5 bilateral lesions and tumor involved corpus callosum in 5, basal ganglia-thalamus in 4, and brain stem in 2. There was no operative mortality but four patients died during the follow-up. The mean survival period for 11 patients was 20.5 months from the time of diagnosis. In univariate analysis, the lesion involving corpus callosum, basal ganglia-thalamus and brain stem correlated significantly with the short length of survival(p<0.05). Also, postoperative radiation as a adjuvant therapy prolonged the patient's survival(p<0.05). Conclusions : In the management of gliomatosis cerebri patients, early detection by MR imaging, active management of increased intracranial pressure, decompressive surgical removal and postoperative adjuvant therapy such as radiation is thought to be a good treatment modality.

Bradyrhizobium japonicum with different colony morphology populated in five Yeongnam soils of Korea was examined for intrinsic antibiotic resistance to eight antibiotics, serological property by immunoblot and immunodiffusion, and protein profile differentiation by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Colony morphological distribution of one hundred and twenty B. japonicum isolates was 47% for "dry". 41% for "wet", and 12% for "dry/wet" type. The total isolates showed such a strong correlation between the morphology and antibiotic resistance. Colony morphology, which though was dominantly consisted of the same type within a serogroup, wasn't absolutely linked to serological property of B. japonicum. Based on these data, colony morphology was too simple to identify variations with B. japonicum isolates : antibiotic resistance such complicated compared with serological analyses.

In the natural, there exist several kinds of radioactive isotopes. From atmospheric weapon tests and then some isotopes are naturally radioactivity above all things, nuclear power plant operation and man-made radioactive isotopes concern steadily growing in the environment. During the fission process of nuclear weapon tests and nuclear power plant operation, more than 200 radioactive isotopes are generated. Among them, $^{90}Sr$ and $^{137}Cs$ has been regarded as very important isotopes due to characteristics. In this paper, a quantitative analysis method of environment low level $^{90}Sr$ is studied. Radioactivity level of the environmental $^{90}Sr$ is very low, and it emits continuous beta spectrum, and $^{90}Sr$ exists together with $^{89}Sr$, $^{90}Y$ and other radioactive isotopes. It very difficult to make the quantitative analysis of $^{90}Sr$. For the analysis of low level radioactive strontium, enrich and chemical separation of strontium from the other radioactive isotopes are needed. For the estimation of strontium recovery ratio, so called SGAT(Strontium Gravimetric Analysis Technique) was generally used among the domestic research groups, and chemical procedures were developed appropriation for the SGAT, Recently, by using ICP(Inductively Coupled atomic Plasma emission spectrophotometer), amounts of stable atoms can be measured easily and accurately to the extend of ppm or ppb. In this paper, new chemical procedures are developed to exploits the ICP technique. New developed method has simpler chemical treatment procedures and then it gives more accurate results compared with the traditional SGAT.

Objectives : We investigated the association of Val108/158Met polymorphism on catechol-O-methyl transferase(COMT) gene with smooth pursuit eye movement(SPEM) abnormality in Korean schizophrenia patients. Methods : We measured SPEM in 217 Korean schizophrenia patients(male 116, female 101) and divided them into two groups, one was a good SPEM function group and the other was a poor SPEM function group. Then we analyzed Val108/158Met polymorphism on COMT gene. We compared the differences of genotype and allele distributions of the polymorphism on COMT gene between the two groups. Results : The natural logarithm value of signal/noise ratio(Ln S/N ratio) of the good SPEM function group was $4.39{\pm}0.33$(mean${\pm}$s.d.) and that of poor SPEM function group was $3.17{\pm}0.71$. There were no statistically significant differences of age and male/female ratio between the two groups. There were no significant differences of genotype or allele distributions of the Val108/158Met polymorphism on COMT gene between the two schizophrenic groups. Conclusions : The results suggest that Val108/158Met polymorphism on COMT gene is not related to SPEM function abnormality in schizophrenia.

Objective:There have been a kind of transmethylation theory that high homocysteine serum concentration affects schizophrenia by neurotoxic mechanism and clinical reports that some schizophrenic patients with high homocysteine were improved by high folate ingestion. This study was done to confirm previous research results and find the clinical characteristics of schizophrenia showing high serum homocysteine and low folate. Method:We compared the serum levels of homocysteine, folate and vitamin B12 level between 234 schizophrenic patients(male 99, female 135) group and 234 normal controls(male 99, female 135) group. The subjects of two groups were age and sex matched. The evaluated clinical characteristics items were sex, age, onset of disease, hereditary loading, disease course, hallucination and subtype of schizophrenia. Results:1) Homocysteine level of the schizophrenia group was significantly higher than the normal control group and folate level of the schizophrenia group was significantly lower than the normal control group. Homocysteine level was more negatively correlated with folate level in the schizophrenia group than the normal control group. 2) The percentage of high homocysteine(above 12.46umol/L;90 percentile of normal control) was 33.8% of schizophrenia patients and 51.5% of male schizophrenia. The percentage of low folate(below 3.8nM/L;bottom tertile of normal control) was 66.2% of schizophrenia. 3) In low folate group and not-low folate group, schizophrenia showed significantly higher homocysteine level than normal control. Especially, low folate schizophrenia group showed significantly higher homocysteine level than low folate normal control group. Conclusions:Some schizophrenia patients with high serum homocysteine may be genetic defector and having low folate serum level. In that case, folate ingestion could be a good management for clinical improvement.

Aspirin-intolerant asthma (AIA) is characterized by severe asthmatic attack after ingestion of aspirin and/or non-steroidal anti-inflammatory drugs. In this study, we investigated the relationship between Prostaglandin E2 receptor (PTGER) gene family polymorphisms and AIA in 243 AIA patients and 919 aspirin-tolerant asthma (ATA) controls of Korean ethnicity in two separate study cohorts. After genotyping 120 SNPs of the PTGER gene family for the $1^{st}$ cohort study, four SNPs in PTGER1, ten in PTGER3, six in PTGER3, and a haplotype of PTGER2 showed association signals with decreased or increased risk of AIA. Among the positively associated SNPs, one in PTGER1 and four in PTGER3 were analyzed in the $2^{nd}$ cohort study. The results show that rs7543182 and rs959 in PTGER3 retained their effect, although no statistical significance was retained in the $2^{nd}$ cohort study. Our findings provide further evidence that polymorphisms in PTGER3 might play a significant role in aspirin hypersensitivity among Korean asthmatics.

We are investigated about the Hepatitis infection risk of the funeral director related to wearing PPE(Personal Protect Equipment) within Metropolitan, Chungcheong and Gyeongsang regions in Korea. We are classified that the vaccinated group was classified as low risk group and the non-vaccinated group was classified as high risk group. And we are analyzed the risk rate of infection based on whether or not to wear PPE(personal protective equipment) among high-risk groups. The result is as follows. The mask wearing rate of high-risk group about HAV(hepatitis A virus) is three times lower than that of low-risk group. The surgical glove wearing rate of high-risk group about HBV(hepatitis B virus) is twice lower than that of low-risk group. The surgical glove and mask not wearing rate among the high-risk group observe that potential infection risk was high 4.23 times and 3.5 times, respectively. We are concluded that increasing the risk of potential infection risks from the funeral director could result in increased risk of infection to national public health, including the bereaved family. We are suggested that the funeral director must be bound to vaccinate against hepatitis and make PPE mandatory. It is deemed necessary for the government to develop policies to promote personal health and national health care.
