This study was to examine the positive and negative affect related to psychological characteristics of each Sasang types using Positive and Negative Affect Schedule (PANAS) with 78 students from School of Korean Medicine, Pusan National University. After determining the Sasang types by QSCC II, the psychological characteristics of each Sasang types were analysed by PANAS. We did ANOVA analysis with eight related scales and found significant differences between the Tae-Eum type ($18.71{\pm}8.75$, $6.47{\pm}3.36$, $6.31{\pm}2.47$, $3.18{\pm}2.77$, $10.94{\pm}10.08$) and the So-Eum type ($13.38{\pm}6.03$, $4.55{\pm}2.23$, $4.19{\pm}2.16$, $5.81{\pm}4.20$, $1.83{\pm}9.17$, respectively) in Positive Affect (PA) (F=3.931, p=0.024), PA-Joy (F=3.991, p=0.023), PA-Interest (F=5.025, p=0.009), NA-Afraid (F=3.118, p=0.050), and Difference between Positive and Negative Affect (DPN) (F=6.355, p=0.003) scores. The post-hoc analysis showed that the Tae-Eum type ($18.71{\pm}8.75$, $6.47{\pm}3.36$, $6.31{\pm}2.47$, $10.94{\pm}10.08$) has significantly higher score than So-Eum type ($13.38{\pm}6.03$, $4.55{\pm}2.23$, $4.19{\pm}2.16$, $1.83{\pm}9.17$, respectively) in PA (p=0.018), PA-Joy (p=0.021), PA-Interest (p=0.017), and DPN (p=0.002) scores. The So-Eum type ($5.81{\pm}4.20$) showed significantly (p=0.047) higher score than the Tae-Eum type ($3.18{\pm}2.77$) in NA-Afraid. Results demonstrated distinct affect profile differences between Tae-Eum and So-Eum Sasang types using PANAS. This study may serve as the foundation in identifying psychological traits of Sasang types, especially regarding the aspect of affect.

This study aims to propose color affective model of indoor space by evaluating subjects' physiological responses according to the types of behavioral and affective system. 99 subjects(44 females, 55 males) in their 20s, who had no disorders in visual perception, participated in the experiment. To categorize the subjects based on behavioral and affective system, BAS/BIS scale and Affective scale were used. Color stimuli were composed of five basic colors and three tones: vivid, pale and dull tone of R, Y, G, B, P. For physiological experiment, right and left prefrontal alpha activity was measured to analyze prefrontal EEG asymmetry. Participants were exposed to fifteen color stimuli for 20 seconds each other under the positive and negative emotional condition in a research room with the natural light blocked. The results and conclusion of this study are as follows. Along with factors of behavioral and affective system, cluster analysis was carried out and four types were classified. Type A had high BAS sensitivity, especially high 'drive' trait, and showed high levels of 'anxiety' and 'anger'. Type B had low BAS sensitivity, especially low 'fun seeking' and low 'drive' trait, and showed low levels of 'anxiety' as well as low levels of 'happiness'. Type C had low BIS sensitivity and showed high levels of 'happiness' and low levels of 'sadness'. Type D had high BIS sensitivity and showed high levels of 'lethargy' and 'sadness'. As a result of EEG signal analysis of color stimuli, Type B, Type C, and Type D showed significant differences in prefrontal alpha asymmetry under the negative emotional stimuli. Type B showed more left prefrontal activation in the spaces with pale R and dull G. Type C showed more left prefrontal activation in the spaces with vivid Y and B, pale R, and dull R, G, P. Type D showed more left prefrontal activation in the spaces with vivid Y and P, pale R, Y, P, and dull R, Y, G, B, P. The group of high BAS sensitivity was not influenced by color stimuli under the emotional conditions, whereas the group of high BIS sensitivity was affected by color stimuli under the negative emotional conditions. They showed left prefrontal activation when they were exposed the spaces with vivid, pale, dull tones of Y and P wall.

The electron transport properties of Y-type zigzag branched carbon nanotubes (CNTs) are of great significance for micro and nano carbon-based electronic devices and their interconnection. Based on the semi-empirical method combining tight-binding density functional theory and non-equilibrium Green's function, the electron transport properties between the branches of Y-type zigzag branched CNT are studied. The results show that the drain-source current of semiconducting Y-type zigzag branched CNT (8, 0)-(4, 0)-(4, 0) is cut-off and not affected by the gate voltage in a bias voltage range [-0.5 V, 0.5 V]. The current presents a nonlinear change in a bias voltage range [-1.5 V, -0.5 V] and [0.5 V, 1.5 V]. The tangent slope of the current-voltage curve can be changed by the gate voltage to realize the regulation of the current. The regulation effect under negative bias voltage is more significant. For the larger diameter semiconducting Y-type zigzag branched CNT (10, 0)-(5, 0)-(5, 0), only the value of drain-source current increases due to the larger diameter. For metallic Y-type zigzag branched CNT (12, 0)-(6, 0)-(6, 0), the drain-source current presents a linear change in a bias voltage range [-1.5 V, 1.5 V] and is symmetrical about (0, 0). The slope of current-voltage line can be changed by the gate voltage to realize the regulation of the current. For three kinds of Y-type zigzag branched CNT with different diameters and different conductivity, the current-voltage curve trend changes from decline to rise when the branch of drain-source is exchanged. The current regulation effect of semiconducting Y-type zigzag branched CNT under negative bias voltage is also more significant.

Let {${\Omega}$, $\mathcal{F}$, P} be a probability space and {$X_n|n{\geq}1$} be a sequence of random variables defined on it. A finite sequence of random variables {$X_n|n{\geq}1$} is said to be conditionally negatively associated given $\mathcal{F}$ if for every pair of disjoint subsets A and B of {1, 2, ${\cdots}$, n}, $Cov^{\mathcal{F}}(f_1(X_i,i{\in}A),\;f_2(X_j,j{\in}B)){\leq}0$ a.s. whenever $f_1$ and $f_2$ are coordinatewise nondecreasing functions. We extend the H$\grave{a}$jek-R$\grave{e}$nyi-type inequality from negative association to conditional negative association of random variables. In addition, some corollaries are given.

The purpose of this study was to examine the effect of social support on type 2 diabetes by classifying it into diabetes and impaired fasting blood sugar, a pre-diabetic state. Subjects of this study were 22,846 adults aged 30 years or above who agreed and registered to participate in the "Korean Health Examine Cohort (KOEX)" study that simultaneously collects questionnaires and biological samples at 8 university hospitals around the nation. Normal fasting blood sugar was defined as below 100 mg/dL, and impaired fasting blood sugar was defined as 100~125 mg/dL. Diagnosis of diabetes was defined as fasting blood sugar of 126 mg/dL or above, diagnosis by a doctor, or medication of insulin or oral hypoglycemic agent. Social support groups were divided into 4 groups, and Group 1 (G1) had high positive support and low negative support. This is the reference group with the highest social support. During multivariate analysis, female group (G3) that had high positive support and high negative support showed prevalence of impaired fasting blood sugar 1.19 times higher (95% CI = 1.02~1.41) than G1. As this study confirmed that social support increases fasting blood sugar of women after correction for socioeconomic status, health behavior, and biological and medical variables, it implies the importance of social relations such as social support in addition to management of personal risk factors for prevention of type 2 diabetes.

Purpose: The purpose of this study was to investigate the relationship among nursing organizational culture, work performance, and workplace bullying of nurses, and to identify the factors that affect workplace bullying. Methods: The design of this study was descriptive research, and the data were collected from October 26 to November 5, 2018. The research participants were 210 nurses in six general hospitals in G province. The data were analyzed by descriptive statistics, a t-test, one-way ANOVA, Scheff? post-hoc test, Pearson's correlation coefficient, and a stepwise multiple regression using SPSS 22.0. Results: The workplace bullying type showed negative correlations with innovation-oriented culture, relation-oriented culture, and work performance. The workplace bullying consequence showed negative correlations with the innovation-oriented culture, relation-oriented culture, and work performance, and showed positive correlations with the workplace bullying type. The factors influencing the results of the workplace bullying consequence were workplace bullying type followed by relation-oriented culture, and unmarried status. Conclusion: Workplace bullying among nurses was related to the nursing organizational culture and work performance. Therefore, in order to reduce the turnover rate of nurses and to help them adapt well to the nursing organizational culture, a bullying prevention and intervention program is necessary.
