The purpose of this study was to analyze the relationship between motivation level, job satisfaction along with private security employees job style. For accomplishing this purpose of the study, the 262 subject were selected by the cluster random sampling method from private security employees in 6 private security companies located in Seoul and Kyoung-gi do. The survey questionnaires were used to collect data. The questionnaire for motivation level was developed by Frills and Knox(1972), Quinn and Shephard(1978) and standardized in Korean language by Young-In, Hur(1995) and the job satisfaction was developed by Rizzo(1970) and standardized in Korean language by Yong-Nam, Joo(1993). The statistical methods utilized in this study for analyzing the collected data were reliability analysis, descriptive statistics, Chi-square, t-test, One-way ANOVA, and standard multiple regression analysis. From the analysis of this study, the following conclusions were obtained: Firstly, the motivation level, job satisfaction along with private security employees are partially different by the socio-demographic characteristics. Secondly, the motivation level is not different by the private security employees job style. Thirdly, the job satisfaction is partially different by the private security employees job style. In detail, in job condition along with job style, safe employees are more satisfaction than security employees. Lastly, the motivation along with private security employees influence on the job satisfaction. In detail, the achievement needs, role conflict, and autonomy influence on the job condition and also the role conflict and autonomy influence on the role value.

Objectives : We purposed to objectify the pattern diagnosis of Tic disorders through factor and reliability analysis regarding a pattern identification questionnaire concerning Tic disorders in children. Methods : We chose and studied 144 children who were pattern-diagnosed out of 200 tic disordered children who visited H hospital in Seoul from January 2006 to April 2011. Results : 1. TTD (50%) was the most common type and the occurrence rate in male children was higher(4.76:1). Also, the rate of hospital visits was highest at the age 8(23.6%). 2. In results concering pattern diagnosis, Gan-poong-nae-dong was most frequently diagnosed in 53 patients (36.8%), and Dam-hwa-yo-sin (42 patients), Gan-sin-um-her (30 patients), and Bee-her-gan-wang (6 patients) . 3. In an attempt to verify the reliability of the questionnaire, the coefficient regarding the whole questions (Cronbach α) came to 0.909. Moreover, the reliability coefficient foreach sub factor was 0.687 in Gan- poong-nae-dong, 0.817 in Dam-hwa-yo-sin, 0.851 in Bee-her-gan-wang, and 0.726 in Gan-sin-um-her, respectively. Thus, their consistency was ensured. 4. In exploratory factor analysis concerning the most common five questions in the questionnaire, the questions of Dam-hwa-yo-sin and Gan-poong-nae-dong appeared to be part of different factors. While, Gan-sin-um-her and Bee-her-gan-wang questions showed that they belong to the same factors. 5. In factor analysis excluding both Gan-sin-um-her and Bee-her-gan-wang questions, both showed significant results; however, the one excluding Gan-sin-um-her showed improved results. Conclusions : From the above results concerning the Pattern Identification Questionnaire for Tic Disordered children, three separated patterns of Bee-her-gan-wang, Dam-hwa-yo-sin, Gan-poong-nae-dong are thought to be available for clinical use. However, further validity studies are needed.

Purpose: The treatment of triple-negative breast cancer (TNBC) remains challenging, due to the absence of estrogen, progesterone, and human epidermal growth factor receptors. This study was designed to evaluate the efficiency and safety of cytokineinduced killer (CIK) cell immunotherapy, following regular chemotherapy, for patients with TNBC. Methods: A total of 340 patients with postmastectomy TNBC, from January 1, 2010 to June 30, 2014, were included in this retrospective study. Seventy-seven patients received CIK cell immunotherapy, following regular chemotherapy (arm 1), and 263 patients received regular chemotherapy alone (arm 2). The primary aim was overall survival (OS) and disease-free survival (DFS), and the treatment responses and adverse events were also evaluated. Results: The 5-year DFS and OS rates in arm 1 were 77.9% and 94.3%, compared with 69.8% and 85.6% in arm 2, respectively (p=0.159 and p=0.035, respectively). This clearly shows that there was no statistical difference in the 5-year DFS between the two groups. Multivariate analyses of arm 1 indicated that a Karnofsky performance score (KPS) ≥90 and stage I/IIA disease were significantly associated with a prolonged DFS period (hazard ratio [HR], 0.25; 95% confidence interval [CI], 0.09–0.74; p=0.012; and HR 0.21; 95% CI, 0.06–0.82; p=0.024, respectively), but a KPS ≥90 and stage I/IIA disease were not independent prognostic factors for OS. Toxicity was mild in patients who received the CIK therapy. Conclusion: The data suggested that CIK cell immunotherapy improved the efficiency of regular chemotherapy in patients with TNBC, and the side effects of CIK cell immunotherapy were mild.

An in vitro experiment was conducted to examine the effects of defaunation(removal of protozoa) on production of conjugated linoleic acid (CLA) when incubated with ground ryegrass hay and plant oils ((linoleic acid (C18:2)-rich sunflower oil (SO) and linolenic acid (C183)-rich linseed oil (LO)) in the form of emulsion with egg albumin in vitro. Sodium lauryl sulfate as a defaunation reagent was added into the culture solution at a concentration of 0.000375g/ml, and incubated anaerobically for up to24h at 39℃. Defaunation decreased (P<0.05-0.001) the concentration of cis9, trans11-CLA (P<0.001), trans10, cis12-CLA (P<0.01) and total CLAs (P<0.001) at 6 and 24 h incubations compared with faunation. The concentrations of cis9, trans11-CLA and total CLAs were higher (P<0.001) by SO supplementation than those by LO at all incubation times. Interactions between defaunation and plant oil were found in C18:0 (P<0.01-0.001)from6incubations, cis9, trans11-CLA (P<0.01-0.001) and total CLAs (P<0.01-0.001) at 3, 6 and 24 h incubations.

Background/Aims: The aim of this study was to investigate whether genetic variations at positions -1082, -819, and 592 in the interleukin (IL)-10 promoter affect IL-10 production in children with irritable bowel syndrome (IBS). Methods: Ninety-four children with IBS and 102 children as healthy controls (HCs) were enrolled. Genomic DNA was extracted, and IL-10 -1082, -819, and -592 polymorphisms were detected by direct sequencing from all participants. Peripheral blood mononuclear cells (PBMCs) from 46 IBS children and 38 HCs were isolated and cultured with and without 5 ng/mL Escherichia coli lipopolysaccharide (LPS). IL-10 levels in the culture supernatants were measured by enzyme-linked immunosorbent assay. Results: There were no significant differences in the distribution of IL-10 -1082, -819, and -592 polymorphisms or in the allele and haplotype frequencies between IBS children and HCs. PBMCs from children with IBS had significantly lower IL-10 levels after LPS stimulation than PBMCs from HCs (p=0.011); however, LPS-induced IL-10 levels in PBMCs with different genotypes of -819 and 592 polymorphisms were not significantly different between IBS patients and HCs. Conclusions: Although significantly lower LPS-induced IL-10 production by PBMCs was noted, it is unlikely that IL-10 production was fully genetically determined in our IBS children.

In this study, poly(sodium p-styrenesulfonate)/poly(methyl methacrylate) particles were facilelyprepared by in situ cross-linked polymerization followed with a liquid–liquid phase inversion technique. The particles exhibited selective adsorption for cationic dyes due to the negatively charged sulfonicgroups. The intra-particle diffusion process was the rate-limiting step for the adsorption of methyleneblue. More than 90% of cationic dye was removed by the adsorption column of the particles after threecirculations. The particles could be facilely fabricated and industrially used for wastewater treatment.

This study investigates the influence of varying concentrations of boric acid (BA) preservative on the physical and mechanical properties of light red meranti (LRM) found in Sarawak. LRM or Shorea leprosula samples were treated with various concentrations of BA via the dip diffusion method using American Society for Testing and Materials (ASTM) standards. The physical property, particularly the retention rate and mechanical properties, bending strength, modulus of elasticity (MOE), tensile and compression strength parallel to grain of impregnated and control samples were tested to determine the effects of BA preservative. The retention rate was found to increase with increasing BA concentration and higher surface area to volume ratio. The mechanical properties in terms of the MOE and tensile strength parallel to grain were found to be greater than those of the control samples, whereas the bending strength and tensile strength parallel to grain were lower. Amongst the results, only the retention rate and MOE showed significant interaction effects at 5% level of significance between all factors tested (samples size and BA concentration for retention rate and BA concentration for MOE).
