  • An nprX gene of Bacillus subtilis NS15-4 encoding a neutral protease was cloned and its molecular characteristics were analyzed. The complete nucleotide sequence indicated that there is an open reading frame (0RF) possibly encoding 521 amino acid polypeptide. The ORF used all codons expected two cysteine and a proline having a codon bias index (CBI) of 0.09 in Escherichia coli. There were homologous sequences to the consensus sequence of -35 and -10 regions of E. coli promoters and to a Shine-Dalgarno (SD) sequence located 25 bp downstream of a mojor transcription initiation site. Moreover, there were also five minor transcription initiation sites at 6. 7. 8. 14 and 15 nt downstream of the major site. Northern blot analysis revealed the presence of about 1.8 kb mRNA transcript in E. coli having the nprX gene. The nucleotide sequence was identified in GenBank to be a gene for a neutral protease of B. sutilis with six nucleotide difference in the ORF region. The flanking regions of the NprX ORF showed much more differences form those of other neutral protease genes except the nprE gene of B. subtilis, which has the most homology to the nprX gene, and of which the flanking regions were identical to those of the nprX gene.

  • Purpose: The purpose of this study was to investigate QOL and the factors related to family caregivers who care for Amyotrophic Lateral Sclerosis (ALS) patients. Methods: The subjects were 83 family caregivers caring for ALS patients who visited the neurology outpatient section of a tertiary hospital located in Seoul between January and July of 2008. Their demographic characteristics were assessed and data were collected using the amyotrophic lateral sclerosis functional rating scale (ALSFRS), the caregiver burden inventory (CBI), HADS, and SF-36. Results: The mean score of the physical health component (PHC) of the family caregiver's QOL was $62.6{\pm}24.4$, and the mean score of the mental health component (MHC) of their QOL was $57.7{\pm}22.4$. The mean score of caregiver burden was $76.5{\pm}30.7$. Anxious family caregivers amounted to 55.4% and depressed family caregivers accounted for 63.9% overall. In a multivariate analysis, the PHC of QOL was explained by caregiver burden (41.1%), depression (9.4%), caregiver gender (3.8%), and caregiver age (3.1%). Anxiety (39.8%), caregiver burden (10.9%), patient gender (5.4%) and depression (1.7%) were predictive factors of the MHC of QOL. Conclusion: Caregiver burden and depression affected both the PHC and the MHC. Caregiver burden affected the PHC more than it did the MHC of QOL, but anxiety affected the MHC more than it did the PHC of QOL.

  • The purpose of this study was to identify factors affecting family caregiver burden, and to identify the relationship between family caregiver burden and family function /self-care of psychiatric out-patient. These data were collected by questionnaire from September 20 to October 8, 1993. The subjects were 285 family caregiver of psychiatric out-patients. The instruments used in this study were Caregiver Burden Inventory(CBI) by Novak(1989), self-care performing by Yu(1992), and Family APGAR by Smilkstein(1979). The data were analyzed by cronbach's $\alpha$, mean, standard deviation, percentage, t-test, ANOVA, Pearson's correlation coefficient, and Stepwise Multiple Regression with SPSS /pc+ program. The result of this study were as follows ; 1. The means of family caregiver Burden revealed total 2.00, Time-Dependence Burden 78, developmental Burden 2.22, physical Burden 1.90, social Burden 1.43, emotional Burden 2.18, financial Burden 1.51. family caregiver burden score showed moderate level. time-dependence burden showed the highest score and social burden showed the lowest score. 2. The means of family function revealed total 5.67. 7 through high-21.4% (61), low through 3-38.6%(110). family function score showed moderate level. 3. The means of patient's self-care performance revealed total 137.71. self-care performance showed moderate level. 4. A ststistically significant correlation between family caregiver burden and patient's demographic variables, age (F=3.83, p<.01), marrital status(F=3.50, p<.01), job(F=3.17, p<.01), diagnosis(F=4.46, p<.01), income (F=4.46, p<.01). No significant differences between family caregiver burden and prevalent period, religion, sex (p>.05). S. A ststistically significant correlation between family caregiver burden and family's demographic variables, age (F=7.34, p<.01), sex(t=-2.63, p<.01), education level(F=7.61, p<.01), income (F=8.13, p<.01), relation with patient (F=6.92, p<.01), job(F=2.03, p<.05), medical service (F=3.89, p<.05), presence of chronically ill without patient(t=-2.01, p<.05) 6. Family function was the highest factor predicting family caregiver burden(R=.4168, $R^2=.1737$), low education level of family, patient's self-care, family income accounted for 36% in family caregiver burden.

  • 본 연구는 2011년 100ha 이상의 대형산불 피해지인 울진과 영덕지역을 대상으로 하였으며 산불피해강도를 평가하기 위해 현장조사와 고해상도 위성영상자료 분석을 병행하였다. 위성영상자료 분석 시 산불피해지역의 피해강도를 가장 적절하게 평가할 수 있는 영상분류기법들을 비교 분석하여 최적의 피해강도 평가방법을 선정하였다. 대형산불 피해지역의 최적의 피해강도 평가기법으로는 현장조사에서 획득한 트레이닝 지역의 정보를 이용한 최대우도법을 적용하였을 때 가장 좋은 평가결과를 보였다. 산불피해강도의 정확도 검증 결과, 평균 전체정확도는 88.38%와 Kappa coefficient는 0.8147로 나타났다. 분류정확도는 최대우도법, NDVI, 최소거리법 순으로 나타났다. 산불피해강도 현장조사 결과와 위성영상자료에서 추출한 피해강도의 상관관계는 울진산불 피해지에서 r = -0.544, 영덕산불 피해지는 r = -0.616으로 나타났다.
