The purpose of this study is to investigate 1) the level of the city housewives' sense and behavior of wedding and ancestral service according to the background variables, 2) the relationship of the sense of wedding and ancestral service and behavior, and 3) what the most influential factors are. For the purpose of this study, 700 questionnaire were distributed to the housewives who live in Seoul and collected during the February 1989. And the measuring instruments are composed of 9 questions, 11 questions of the sense of wedding service, 12 questions of the sense of ancestral service, 11 questions of the behavior of wedding service, and 12 questions of the behavior of ancestral service. To obtain the sense and behavior of wedding and ancestral service scale, item analysis through Pearon's correlation and factor analysis, frequency distribution, percentile, mean, standard deviation, t-test, F-test, Pearson's γ, Paired-t-test, Duncan's Multiple Range Test, and Stepwise multiple Regression were used for data analysis. The major fidnigs are as follows: 1. The general tendency of the city housewives' sense of wedding service was modern. That of the city housewives' sense of ancestral service was the mid level of the traditional and the modern. According to background variable (ie: age, educational level, the number of children, the duration of marriage, religion, the existence of job, the existence of married son and daughter), the city housewives' sense of wedding service is different significantly. Accoring to background variable(ie: age, educational level, the average home income a month, the number of children, the duration of marriage, religion, the existence of married son and daughter), the city housewives' sense of ancestral service is different significantly. 2. The general tendency of the city housewives' behavior of wedding service was modern. That of the city housewives' behavior of ancestral service was somewhat modern. According to background variable(ie: age, educational level, the number of children, the duration of marriage, the existence of married son and daughter, the form of family), the city housewives' behavior of wedding service is different significantly. According to background variable(ie" age, educational level, the number of children, the duration of marriage, religion, the existence of job, the existence of married son and daughter), the city housewives' behavior of ancestral service is different significantly. 3. There were positive correlation between the city housewive' sense and behavior of wedding and ancestral service(P<.001). And the housewives' sense of wedding service was modernized than that of ancestral service, the housewives' behavior of ancestral service was modernized than that of wedding service. 4. The city housewives' sense of wedding service was the duration of marriage(β=-.226), influential factor. And influential factors on that of ancestral service were educational level(β=.250), the existence of married son and daughter(β=-.123), number of children(β=-.101). The influential factors on the city housewives' behavior of wedding service were age(β=-.193), the form of family(β=.097). And that of ancestral service were educational level(β=165), the number of children(β=-.157).

A phenomenon in the unplanned urban sprawl of Cheong-ju city has to be rest-rained from disposing and to develop, though progress in urbanization inevitably decreases rural area. So, this thesis aims at reviewing, revising and guiding toward the more effective land use planning practice and zoning mechanism and system of Cheong-ju city. I proposed that land use planning should be had several factors and thereupon that Korean zoning mechanism and system including Building Code should be amended because of inducing human activities in buildings and facilities not to demarcate and plan every one of them. First, the factors of urban planning are a rather diversified approach to it than a unified, supplementation of the applicable difference in time between preparing and appling it, a solid controlling system, a micro and macro planning theory and giving serious consideration for the inertia from the existing land use. Second, the applicable amendments for our zoning mechanism including Eluding Code are as follows; a need of reorganization for Zoning Ordinance appricated to different regulation concerning a scale and peculiarity of a oily, a decision of the different earmarked confinement in area to different zone ana from Zoning Ordinance in City Planning Law, a demarcated facilities and the more detailed land use concerning human activies than the exsisting and entrusting decision on the ways and processes of it to every rural city planning committee, a settlement of zone ana area considering for block-unit and Planned Unit Development(P. U. D.), and a need of security jurisprudence in order to solve the zoning regulation rather in City Planning Law than in Building Code that our zoning regulation and controlling system are depended on. According to these applicable amendments to Cheong-ju city, I proposed the conceptions of Cheong-ju city land use planning are as follows; a reinforcement with one cored pattern of urban land use, a selection of gradual urban sprawl by way of city development and renewal, a strengthening accessibility to the core of the city with Plurizing the system of arterial roads, a choice of priority to conservation at the core of tile city and security of open spaces and parking area at the area of the city, a harmonization between development and conservation at the inner ring area that is situated between the core and periphery reserved area in order to develop in the future, a buffered open space situated at the congested area with heterogenous functions, and a completion of urban open space system. The proposal made here so far is for the hope of the better structure of Cheong-ju city that should be granted to the peculiarity developed with educational, cultural, conservative and self-sufficient city functions.

Background: In order to evaluate the effect of pH, known as a critical factor for shaping the biogeographical microbial patterns in the studies by others, on the bacterial diversity, we selected two sites in a similar geographical location (site 1; north latitude 35.3, longitude 127.8, site 2; north latitude 35.2, longitude 129.2) and compared their soil bacterial diversity between them. The mountain soil at site 1 (Jiri National Park) represented naturally acidic but almost pollution free (pH 5.2) and that at site 2 was neutral but exposed to the pollutants due to the suburban location of a big city (pH 7.7). Methods: Metagenomic DNAs from soil bacteria were extracted and amplified by PCR with 27F/518R primers and pyrosequenced using Roche 454 GS FLX Titanium. Results: Bacterial phyla retrieved from the soil at site 1 were more diverse than those at site 2, and their bacterial compositions were quite different: Almost half of the phyla at site 1 were Proteobacteria (49 %), and the remaining phyla were attributed to 10 other phyla. By contrast, in the soil at site 2, four main phyla (Actinobacteria, Bacteroidetes, Proteobacteria, and Cyanobacteria) composed 94 %; the remainder was attributed to two other phyla. Furthermore, when bacterial composition was examined on the order level, only two Burkholderiales and Rhizobiales were found at both sites. So depending on pH, the bacterial community in soil at site 1 differed from that at site 2, and although the acidic soil of site 1 represented a non-optimal pH for bacterial growth, the bacterial diversity, evenness, and richness at this site were higher than those found in the neutral pH soil at site 2. Conclusions: These results and the indices regarding diversity, richness, and evenness examined in this study indicate that pH alone might not play a main role for bacterial diversity in soil.

Purpose : The purpose of this research is to measure the correlations among sleep quality, depression and department satisfaction in the students enrolled in the nursing college located in the B city. Method : 268 students enrolled in the nursing college located in the B city participated in this research from the 1st May 2016 to the 31st May 2016. SPSS 18.0 was applied to the collected data to calculate the frequency, percentage, average and standard deviation. In addition, t-test, ANOVA, Scheffe test and Pearson correlation coefficient were used for the analysis. Result : The result of the average sleep quality, depression and department satisfaction in the nursing college students were measured to be $2.41{\pm}0.57$, $3.59{\pm}0.50$ and $3.56{\pm}0.57$ respectively. The sleep quality based on the general characteristics indicated a significant difference when applied to the health status(F=4.46, p=.012). The depression indicated a significant difference when applied to the living with parents(t=-2.18, p=.030) and relationship with friends(F=8.62, p=.000). The department satisfaction indicated a significant difference when applied to the grade(F=3.45, p=.017), personality(F=3.46, p=.033), and reason for applying for their department(F=2.49, p=.044). As a result of analyzing the correlations among sleep quality, depression and department satisfaction in the nursing college students, the sleep quality indicated a negative correlation with the depression(r=-.528, p=.000) and a positive correlation with the department satisfaction(r=.144, p=.018). The depression indicated a negative correlation with the department satisfaction(r=.119, p=.051). Conclusion : It is necessary to conduct a replication research by increasing the number of the research subjects. In addition, it is necessary to conduct a systematic research on the factors influential on sleep quality, depression and department satisfaction in order to develop a program capable of enhancing the sleep quality and decreasing the depression.

A 4.8-kb DNA fragment encoding the P-450 type hydroxylase and ferredoxin genes was cloned from Pseudonocardia autotrophica IFO 12743 that can convert vitamin D$\_$3/ into its hydroxylated active forms. In order to isolate the P-450 gene cluster in this organism, we designed PCR primers on the basis of the regions of an oxygen binding site and a heme ligand pocket that are general characteristics of the P-450 hydroxylase. Sequencing analysis of the BamHI fragment revealed the presence of four complete and one incomplete ORFs, named PauA, PauB, PauC, and PauD, respectively. As a result of computer-based analyses, PauA and PauB have homology with enoyl-CoA hydratase from several organisms and the positive regulators belonging to the tetR family, respectively. PauC and PauD show similarity with SuaB/C proteins and ferredoxins, respectively, which are composed of P-450 monooxygenase systems for metabolizing two sulfonylurea herbicides in Streptomyces griseolus PauC shows the highest similarity with another CytP-450$\_$Sca2/ protein that is responsible for production of a specific HMG-CoA reductase inhibitor, pravastatin, in S. carbophilus. Cultures of Steptomyces lividans transformant, containing the P-450 gene cluster on the pWHM3 plasmid, was unable to convert vitamin D$\_$3/ to its hydroxylated forms.

Purpose: This study examined the associations of job stress and burnout with the quality of life (QOL) among 119 emergency medical technicians (EMTs). Methods: Using a descriptive correlational design, 260 EMTs working in D City or S City completed the questionnaires. Hierarchical multiple regression analysis was conducted to determine the predictors of QOL among 119 EMTs. Results: Overall, there was relatively low job stress among 119 EMTs. There were significant differences in job stress and burnout by general characteristics, especially regarding those of gender, service career, job rank, and self-reported health. In a hierarchical multiple regression, general characteristics explained 29% of QOL (Model I, F=16.369, p<.001). The explanatory power for QOL increased to 49% upon adding job stress (Model II, F=18.737, p<.001), and 59% upon adding burnout (Model III, F=22.621, p<.001). In the last model, self-reported health (${\beta}=.316$, p<.001), job demand (${\beta}=-.130$, p=.009), job insecurity (${\beta}=-.136$, p=.010), lack of reward (${\beta}=-.189$, p=.001), emotional exhaustion (${\beta}=-.196$, p=.004) and lack of personal accomplishment (${\beta}=-.334$, p<.001) were significant predictors of QOL among 119 EMTs. Conclusion: Based on the results, it is necessary to assess and manage job stress and burnout systematically among EMTs, and to develop health improvement programs for better QOL.

Primer $Sj{\ddot{o}}gren's$ Syndrome (pSS) is an autoimmune/inflammatory illness. The platelet indices (PIs) indicate the inflammatory response and activity/severity of many diseases. A vitamin D deficiency is accompanied by the increased tendency of autoimmune diseases. This study investigated whether the vitamin D levels are related to the altered platelet indices in pSS. A total of 261 individuals were included in this analytical cross-sectional study. The laboratory data of pSS patients were evaluated and the relationship between the PIs and vitamin D status was examined. According to these findings, in patients with pSS, the vitamin D levels were lower than the healthy control group (P<0.05). The vitamin D levels were negatively associated with PDW (P=0.012), but positively correlated with PCT (P<0.001). The cut-off point was obtained with receiver operating characteristics (ROC) curves for PDW: 12.53 (AUC 0.921, sensitivity 90%, specificity 85%), for PCT; 0.29 (AUC 0.660, sensitivity 68%, specificity 55%). In multivariate linear regression analysis, the most significant parameters for the effects of PDW are the following: vitamin D (${\beta}=-0.373$; t=-2.626; sig.=0.013) and plateletcrit (${\beta}=-0.308$; t=-2.13; sig.=0.040). A vitamin D deficiency may be accompanied by changes in PIs in pSS. A higher PDW and lower PCT supports the underlying inflammation, which may be vitamin D related useful parameters to consider in approaching to pSS.

To investigate the characteristics of rainwater in Daegu area, parameters such as pH, electrical conductivity, TOC, TIC and TC were analyzed on 34 samples from January to December 2005. Results revealed that higher values were measured in winter than in summer. Furthermore samples that originated from industrial and commercial areas had higher chemical concentrations and conductivity as compared with those from residential and reference areas. Seldom acid-rain occurrence was recorded(27.2%) as compared with non-acid precipitation(72.8%) incidence. Also higher organic carbon fraction(TOC) was detected(72.5%) than inorganic form(TIC)(27.5%) in terms of component ratio with TC. During frequent rainfalls, the concentration of chemicals was decreased to a degree. Conversely, lower rate of rainfall gave out higher chemical values. Thereby the improvement of air qualify in 2005 compare with 2003 report was influenced by the environment authorities' efforts to reduce air pollutions and various factors by the depression of the region's economy.
