This study ascertained convergent influence on state anxiety and its association with subjective happiness, job burnout and psychosocial stress among Hospital Women Administrative Staff(HWAS). The survey period was from July 4, 2018 to July 25, 2018. The subjects were 226 HWAS randomly extracted from 24 hospitals in J area. The data were collected using a structured self-administered questionaries. State anxiety was negatively correlated with subjective happiness, and it was positively correlated with job burnout and psychosocial stress. The covariance structure analysis showed that the lower subjective happiness, and the higher job burnout and psychosocial stress tend to increase state anxiety. In conclusion, in order to reduce the state anxiety of HWAS, it is necessary to increase subjective happiness, to reduce job burnout and psychosocial stress. These results are expected to be used for industrial health education and hospital internal customer management to reduce the state anxiety of HWAS. In the future study, it is necessary to investigate the convergent additional factors that affect the state anxiety of HWAS.

Objective : The purpose of this study was to examine the validity and reliability of the Korean version of Life Balance Inventory (K-LBI) and to present the relationship between life balance and sensory processing. Methods : K-LBI was constructed through forward and backward translation. Convergent validity, internal consistency, and test-retest reliability were tested for college students. To verify convergent validity, correlation analyses between K-LBI and Korean version of Perceived Stress Scale, Korean version of Satisfaction With Life Scale, and Adult Self Report-Achenbach system of empirically based assessment were performed. Split-half reliability and test-retest reliability were also obtained for reliability verification. We performed the correlation analysis between K-LBI and Korean version of Adolescent/Adult Sensory Profile. Results : A significant correlation was found between K-LBI and the scales for convergent validity. A favorable split-half reliability and test-retest reliability were calculated. The positive correlations were found between relationship life balance and sensory sensitivity/sensation avoiding quadrants. The negative correlation was found between challenges life balance and low registration. Conclusion : This study shows that K-LBI is a valid and reliable tool in Korea. It also provides an in-depth understanding of the relationship between life balance and sensory processing.

The present study was conducted to determine convergent factors affecting depression in drinker by age. This was a cross-sectional secondary data analysis study that used the raw data from the Korea National Health and Nutrition Examination Survey in 2014 & 2016. The subjects of the present study were 4,446 middle-aged drinker. Variables related to general characteristics, physical and psychological factors were selected. After a sampling plan compound file was created using IBM SPSS 23.0 program, data were analyzed by giving weights. Depression was influenced by gender (30s, 50-60s), income (30-40s, 60s), education (30-40s), number of family members (30-60s), job (30-60s), eating level (30-40s, 60s), hypertension (40s), DM (30-40s), BMI (30-40s), smoking (30s, 50s), exercise (30s), weight control (60s), drinking binge (30-60s), subjective health (30-60s), subjective body awareness (30-50s), stress (30s-60s), quality of life (30-60s). It is required to design preventive interventions and management plans for depression, considering these factors comprehensively.

The aim of this research is to find out how convergent operation of the learning coaching and compensation system affects the academic self-efficiency and learning performance of university students. In the second semester, a compensation system was prepared based on learning coaching and learning outcomes, made a notice in advance, and conducted a survey before and after operation to measure the academic self-efficacy. In addition, the MLST-II Learning Strategy Diagnosis Examination was conducted on G university students to diagnose the learning tendency. As a result, although G University students felt a reluctance by coaching the learning community and expected negative results during the course of participation in the learning community due to low motivation and low expectation of results, they showed a significant improvement in academic self-efficiency and learning outcomes. Therefore, even students with negative learning tendency will need to consider how to operate these programs in the educational field, as the expert's learning coaching and compensation systems produce positive results for students' academic self-efficiency and learning outcomes rather than leaving them to autonomy.

This study investigated convergent influence on turnover intension and its association with organizational commitment, organizational loyalty and job burnout among some Administrative Staff in Medical Institutions(ASMI). The subjects were 320 randomly selected ASMI from 27 medical institutions in the J region, Data collection was carried out via a structured self-administered questionaries from July 2, 2018 to July 27, 2018. Turnover intension was positively correlated with job burnout, and it was negatively correlated with organizational commitment and organizational loyalty. The covariance structure analysis showed that the higher job burnout, and the lower organizational commitment and organizational loyalty tend to increase turnover intention. The results indicate that the efforts, to increase organizational commitment and organizational loyalty, and to decrease job burnout, are required to decrease the turnover intention of ASMI. The results are expected to be useful for health administration policy and industrial health education to decrease the turnover intention of ASMI. In the following study, the analysis about convergent additional factors of influence on the turnover intention of ASMI will be needed.

The synthesis of well-defined dendrons based on aliphatic polyether dendritic cores and glassy polystyrene peripheries is described. The synthetic route involves a combination of living anionic polymerization and a stepwise convergent method consisting of iterative Williamson etherification and hydroboration/oxidation reactions. On the basis of molecular weight, as characterized by gel permeation chromatography (GPC), the first generation dendron (Generation-1) shows a random coil conformation like a linear polystyrene, while higher generations (Generation-2 and 3) reveal globular forms in solution.

The decoupling design for the one-degree-of-freedom controller system is treated within the $H_{\infty}$ framework. In the present study, we demonstrate that the $H_{\infty}$ performance problem in the decoupling design is reduced into interpolation problems on scalar functions. To guarantee the properness of decoupling controllers and the overall transfer matrix, the relative degree conditions on the interpolating scalar functions are derived. To find the interpolating functions with relative degree constraints, Nevanlinna-Pick algorithm with starting function constraint is utilized in the present study. An illustrative example is given to provide details regarding the solution.

We introduce a new two-point iterative method to approximate solutions of nonlinear operator equations. The method uses only divided differences of order one, and two previous iterates. However in contrast to the Secant method which is of order 1.618..., our method is of order two. A local and a semilocal convergence analysis is provided based on the majorizing principle. Finally the monotone convergence of the method is explored on partially ordered topological spaces. Numerical examples are also provided where our results compare favorably to earlier ones [1], [4], [5], [19].

The convergent synthetic strategy for the emissive dendrimers having the chromophore at core via the coppercatalyzed 1,3-dipolar cycloaddition reaction between alkyne and azide was described. 2,7-Diazido-9,9-dioctyl-9H-fluorene, designed to serve as the core in dendrimer, was stitched with the alkyne-functionalized Frechettype and PAMAM dendrons by the click chemistry leading to the formation of the corresponding fluorescent dendrimers in high yields. The preliminary photoluminescence studies indicated that 2,7-diazido-9,9-dioctyl-9H-fluorene showed no fluorescence due to the quenching effect from the electron-rich ${\alpha}$-nitrogen of the azido group but the dendrimers fluoresced due to the elimination of the quenching through the formation of the triazole ring.

In addition to exceptional abilities and domain-specific aptitudes, frequently creativity potentials are used to explain high achievements in science and technology. In the Guilford tradition, research focuses increasingly on convergent versus divergent thinking, that is, a suspected dichotomy between intelligence and creativity. Despite important insights from this about relationship of ability and creativity, a number of important questions remain unanswered. These relate not only to conceptualization and measurement problems regarding the hypothetical constructs "scientific ability" and "creativity", but also their diagnosis and nurturance in childhood and adolescence. It would appear that, in view of current research paradigms, the role of ability and creativity needs to be redefinded in order to more reliably predict and explain excellent achievements in science and technology. Advances are mostly expected from synthetic approaches. Thus, I will be presenting new theoretical models and empirical research results. Finally, consequences for the prediction and promotion of mathematical-scientific and technical talents will be discussed including the consideration of sex-related problems.
