The purpose of this study is to make it clear that the influence the adults' work-family conflicts affect the family life satisfaction and the work life satisfaction of theirs, according to the personal backgrounds (sex, age, monthly income and whether the person works S days a week or not). The target group of this study is the selected 754 adults who are married with children that are in the employ of the various companies in Seoul and Incheon. The picked data are analyzed to factor analysis, frequencies, means, One-way ANOVA and multiple regression analysis etc..using Spss 11.5 version statistical program. Following is the result of the study: First, the level of work-family conflicts have been shown to be different as the result of verification by sex, age, monthly income and the type of duty(whether working 5days a week or not) out of the personal variables. The study shows that the level of work-family conflicts is different by the subordinate variables of work-family conflicts as the results of male and female comparison. And the older the age, the higher the level of family conflicts.'rho study shows that The level of the places of work conflicts is the highest in the 30s. The smaller monthly income, the higher the level of work-family conflicts. The study shows that the level of family conflicts is high in working 6days a week and the level of work conflicts is high in working 5days a week. Second, such factors for conflicts at home as family support, family expectations and financial difficulties affect the level of satisfaction at work, while such personal backgrounds as monthly pay, kinds of work and age level also play a role. At the same time, satisfaction in family life is influenced by such factors for conflicts at the places of work as support, involvement, expectations and work-overload at the places of work, with such personal backgrounds as monthly pay, age and sex compounding the impact. On the point how much conflicts at work and home affect the satisfaction at home, work and leisure, the study shows that family life does not have noticeable influence in the level of satisfaction at the places of work, whereas situations at the place of work have significant impact on the level of satisfaction in family lives. In other words, the lesser conflicts the work situations cause to family lives, the greater the level of satisfaction at work, home and at leisure.

The purpose of this study is to acquire teaching insights for improving scientific literacy by analyzing the effects of scientific communication skills, science process skills, and logical thinking skills of elementary school students on academic achievement level. The participants are 64, sixth grade elementary school students. Survey materials include the results of Scientific Communication Skill Test (SCST), Test of Science Process Skills (TSPS), Group Assessment of Logical Thinking (GALT), multiple choice test & short answer test, descriptive answer test on science, and academic achievement level test on all subjects. Based on these data, the study analyzed the relationships of science process skills, logical thinking skills, and scientific communication skills, and each category's effect on academic achievement level. Furthermore, under the assumption that scientific communication skills are affected by science process skills and logical thinking skills and directly influence the academic level, the research discovered three types of correlations as a structural model. The results show that there are considerable correlations in scientific communication skills, science process skills, and logical thinking skills. Also, these three abilities have meaningful correlations with learner's writing and descriptive question level on science curriculum and overall academic achievement level; the level of correlation differ a bit by subcategory factors. In conclusion, setting the model, science process skills and logical thinking skills influence scientific communication skill, and the skill directly influences the learner's academic level. Further analysis of the results show that scientific communication skill influences the academic achievement level of all subjects the most.
A descriptive research is studied to identify the physical factors affecting to cognitive function among elderly residents over 65 years old in a community. The data were collected from 352 participants as part of a health-related survey by home visits in Seoul in 2010-2012. Their cognitive function was measured using the Korean form of Hasegawa Dementia Scale(HDS-K) and the collected data were analyzed by using t-test, ANOVA, and multiple regression analysis. From the analysis, the prevalence rate of cognitive impairment was 13.6%. Elderly residents in a community showed different cognition levels by the status of age, change of weight, change of BMI, walking and flexibility exercise. Especially, the lowest cognition level was found in the normal BMI group with decreased BMI change by over 3. The factors influencing on cognition level of the elderly with normal BMI were age, change of weight, change of BMI, and walking exercise. The variance indicated 12.2% as their cognition level. Therefore, for preventing the cognitive impairment of the elderly that were rapidly decreased of BMI, we need the program to manage their nutrition and walking exercise.

Medication non-compliance among the elderly results in medical problems and substantial cost to the health care system. This study investigate predicted variable related to the medication task ability among elderly. This study was done in the selected 4 villages in Kimchun County of Kyungbuk Province from July to August, 1996. The subject was the resident that 202 adults above 60 years of age. The questionnaire of interview included medication task ability, socio-demographic data, COOP/WONCA chart, family ABGAR score. BDI(Beck depression inventory), ADL(activities of daily living), IADL(instrumental activities of daily living), and MMSE-K(minimental state examination-Korean version). The results were as followed : 1. Approximately 49% of study population was taking drug medication currently. We found that 93% of study population was successful at the medication task all alone, 6% was failure at the medication task all alone, so need help partly or completely. 2. Significant variables between group of medication task ability were age, educational attainment, IADL, and MMSE-K in univariate analysis. And significant correlated variables with medication task ability were ADL, IADL, MMSE-K, and BDI in correlation analysis. 3. Major predictors to medication task ability on multiple logistic regression were IADL and sex finally. Findings suggest that IADL is related to medication task ability than other test battery of health status, so IADL could be used to necessary for medication management and add information to conventional methods of assessing mental status.
The purpose of this study was to identify evaluation factors and analyze the relative importance among factors to select a suitable transportation method for transferring the increasing amount of transshipment at multiple terminals at the Busan new port. To accomplish this, the evaluation factors were selected through a literature survey and brainstorming of a group of experts associated with the port operation, and were classified into five major factors and 15 middle factors. The evaluation factors classified hierarchically were surveyed relative to workers in organizations such as shipping companies, port corporations, container terminals, and related ministries. The importance of each factor was calculated using the hierarchical analysis process (AHP). As a result of the importance analysis, priority was assigned in order of safety, productivity, investment efficiency, operational efficiency, and policy conformity. Through this, it was necessary to select a suitable transportation method for the transshipment cargo in terminals while focusing on the cargo and terminal security and preventing accidents. As a result of calculating from six ITT transportation candidates, the priority was determined in order of monorail, Autocon, and so on as ITT transportation suitable for the Busan new port..

Purpose: This article attempted to examine how teeth for restoration is made in a clinical practice and utilize it as future educational material of teeth formation and basic data for additional research. Materials and methods: This experiment investigated the models sent to milling center for production of zirconia crowns. After scanned with Lava CAD/CAM System (3M ESPE, Seefeld, Germany), they are measured on 'ImageJ (version 1.32j, National Institutes of Health, USA)' program and compared and analyzed. Convergence angle from mesio-distal surfaces and bucco-lingual surfaces of each teeth are measured. Also, bucco-lingual diameter of the region lowered as much as 0.4 mm from incisal edge in anterior teeth except canines.(This measure is defined as the Peak 0.4) The analysis of data between each group was conducted by Windows SPSS statistic program, and was proved significant on 95% confidence level by independent t-test, one-way ANOVA and multiple analysis (Sheff${\'{e}}$ test). Results: The mean value of convergence angle was $18.67^{\circ}$ It is ranked as molar ($26.70^{\circ}$) > premolar ($16.87^{\circ}$) > anterior teeth ($14.81^{\circ}$) in the order of mesio-distal convergence angle; anterior teeth ($22.32^{\circ}$) > molar ($20.93^{\circ}$) > premolar ($15.41^{\circ}$) in the order of bucco-lingual convergence angle. The mean value of Peak 0.4 was 1.18 mm. Conclusion: Convergence angle of abutment of zirconia all ceramic crown has difference depending on the location in the arch. Due to the nature of production of zirconia all ceramic crown, convergence angle of abutment and line angle finishing degree can have an effect on internal suitability of restoration.
Staphylococcus aureus (S. aureus) is known as a bacterium that can cause skin infections, respiratory system infections, and sinusitis; however, it can exist as a normal flora rather than a pathogen. Recently, methicillin-resistant S. aureus (MRSA) infections have emerged in the community as a new variant of community-associated (CA)-MRSA. In the present study, S. aureus and MRSA were isolated and cultured by collecting samples from facilities and environments where students and educational personnel have multiple contacts on university campuses; specifically, the nostrils and hands of college students were tested from July to September of 2019. The molecular properties of the isolated MRSA were analyzed, and the one MRSA strain was isolated from the university campuses. One MRSA that was isolated and cultured on campus was the mec complex group A and staphylococcal cassette chromosome (SCC) mec type II, which is a characteristic of healthcare-associated (HA)-MRSA, and SCCmec type V, which is a characteristic of CA-MRSA. This result was similar to other studies wherein the SCCmec type II was detected in SCCmec typing analysis in CA-MRSA. To confirm whether there is a new variant of CA-MRSA in the Republic of Korea, additional follow-up studies on the analysis of virulence factors of MRSA are needed by additionally separating CA-MRSA from the body parts of university students and educational personnel.
Objectives : As the disabled have higher prevalence rates and earlier onsets of chronic diseases than the non-disabled, their participation in mass screening is important for the early detection and intervention of chronic diseases. Nevertheless, in Korea, the disabled have lower participation rates in mass screening services than the non-disabled. The purpose of the study was to find determinants for the participation in the National Health Insurance (NHI) mass screening program among the disabled. Methods : In this study, the NHI mass screening data of 423,076 disabled people, which were identified using the National Disability Registry (2003), were analyzed. Of the factors affecting the participation rates in mass screenings, the following variables were included for the analysis: socioeconomic stati, such as sex, age, category of health insurance program, region and income, disability characteristics, such as disability type, and severity. A multiple logistic regression analysis was used to evaluate the association between the participation rates, disability characteristics variables and demographic variables. Results : The participation rate in mass screening of the disabled was 41.3%, but was lower in females, an age of more than 70 years, self-employed and for those with an average monthly insurance premium over 133,500 Won and in metropolitan legions. The participation rate was 1.31 times lower in females than males (95% CI=1.29-1.33); 3.50 times lower in the elderly (more than 70 years) than the younger (95% CI=3.33-3.67); 1.43 times lower in those who live in metropolitan areas (95% CI=1.40-1.46); 2.59 times lower for those in a health Insurance program for the self-employed than for employees (95% CI=2.56-2.63), 1.19 times lower for the higher income (more than 133,500) than the lower income group (4,400-22,000) for the average monthly insurance premium (95% CI=1.15-1.23): 2.04 times lower for those with brain palsy and stroke disabilities than with auditory impairments (95% CI: 1.97-2.11) and 3.27 times for those with severe compared to mild disabilities (95% CI=3.15-3.40). Conclusions : The disabled with high severity, and locomotive and communication disabilities have lower participation rates in mass screening services in Korea.
Background: Sorafenib is a promising drug for advanced hepatocellular carcinoma (HCC); however, treatment may be discontinued for multiple reasons, such as progressive disease, adverse events, or the cost of treatment. The consequences of sorafenib discontinuation and continuation are uncertain. Materials and Methods: We retrospectively analyzed 88 HCC patients treated with sorafenib from July 2007 to January 2013. Overall survival (OS), post-disease progression overall survival (pOS), and time to disease progression (TTP) were compared for survival analysis. Cox proportional hazard regression was performed to assess the effect of important factors on OS in the overall patient population and on pOS in patients who continued sorafenib treatment. Results: Sorafenib was discontinued and continued in 24 and 64 patients, respectively. The median OS (355 vs 517 days respectively; p=0.015) and median post-PD OS (260 vs 317 days, respectively; p=0.020) were statistically different between the discontinuation and continuation groups. Neither the median time to first PD nor the time to second PD were significantly different between the 2 groups. In the discontinuation group, 3 of the 24 patients (12.5%) suffered disease outbreaks. In Cox proportional hazard regression analysis after correction for confounding factors, BCLC stage (p=0.002) and PD site (p=0.024) were significantly correlated with pOS in patients who continued sorafenib treatment. Conclusions: Sorafenib discontinuation may cause HCC flares or outbreaks. It is advisable to continue sorafenib treatment after first PD, particularly in patients with Barcelona Clinic Liver Cancer stage B disease or only intrahepatic PD.

The purpose of this study is to analyze the effects of the collective characteristics of SMEs on M&A activity on the disclosure effect of mergers and long-term business performance after mergers. From 2000 to 2012, we examine 717 cases of small and medium-sized enterprises (SMEs) using multiple regression analysis and difference analysis. The results of this study are as follows. First, it is confirmed that the effect on the merger announcement effect is the same as the previous study on the Korean capital market listed companies except for the effect of diversification, listing effect, and cross-border effect. In addition, we have found that firms with higher performance in the past have higher excess returns in the disclosure effect of mergers and acquisitions. Second, unlike the previous studies that non-related mergers have a positive effect on long-term operating performance, for the characteristics of SMEs with lower market competitiveness than that of average listed companies, SMEs merging with same industry group companies have a positive effect on long-term operating performance. This study provides a new perspective on the merger and acquisition of SMEs by examining the effects of M&A announcement and long-term performance.
