Purpose: The purpose of this study was to examine the actor and partner effects of self efficacy, marital adjustment and family support on Yangseang in infertile couples using the actor-partner interdependence model. Methods: The participants were 108 infertile couples. Data were collected using the Yangsaeng Scale, Infertility Self Efficacy Scale, Revised Dyadic Adjustment Scale, and Perceived Social Support Scale from March to April in 2016. The Actor-Partner Interdependence Model was used to analyze the actor and partner effects of self-efficacy, marital adjustment and family support on Yangsaeng. Results: The fit indices for the model were Comparative Fit Index (CFI) = 0.99, Normed Fit Index (NFI) = 0.99, Tucker-Lewis Index (TLI) = 0.90, and Root Mean Square Error of Approximation (RMSEA) = 0.01, which met the criteria. We found that only self efficacy had an actor effect on Yangsaeng. Marital adjustment and family support of infertile husbands had an actor effect on the Yangsaeng. In addition, marital adjustment showed an interaction effect. Conclusions: The findings of this study indicate that the level of Yangseang in infertile couples was positively associated with the levels of self efficacy and martial adjustment. Partner effects may be hidden due to much stronger actor effects on Yangseang.

Objectives: Hwa-byung is a mental illness. It is also known as a Korean culture-related syndrome. In traditional Korean medicine, Sihogayonggolmoryeo-tang is used to treat Hwa-byung related neuropsychiatric symptoms. The purpose of this research was to examine the effect of Sihogayonggolmoryeo-tang on Hwa-byung. Methods: A multicenter, randomized, double-blinded, placebo-controlled study was performed for 160 patients with Hwa-byung. Patients were divided into a Sihogayonggolmoryeo-tang group and a placebo group. Treatment period was 8 weeks. Hamilton Rating Scale for Anxiety (HAM-A), Likert scale for major symptoms of Hwa-byung, Hwa-byung Scale (HBS), Korean Beck Depression Inventory (K-BDI), Korean State-Trait Anxiety Inventory (K-STAI), Korean State-Trait Anger Expression Inventory (K-STAXI), and Korean WHO Quality of Life Scale Abbreviated Version (WHOQOL-BREF) were used to evaluate the effect of Sihogayonggolmoryeo-tang on Hwa-byung. We also used an Instrument of Pattern Identification for Hwa-Byung to evaluate different responses for six patterns of patients. Results: Scores of all the measurements improved significantly for each group, showing no significant differences between the two groups. In the case of deficiency of both Qi and blood pattern, the Sihogayonggolmoryeo-tang group showed a significant decrease in the HAM-A score compared to the placebo group. Conclusions: The effect of Sihogayonggolmoryeo-tang on Hwa-byung did not exceed that of the placebo. Further studies involving more elaborate pattern identification are needed.

The past bridge design specifications of Korea didn't include 1imitation on the amount of lap splices in the plastic hinge zone of piers, and so do current specifications. But these specifications include just limitation on the minimal length of lap splices. Thus, a large majority of non-seismically designed bridge piers may have lap splices in plastic hinge zone. In this study, model pier was selected among existent bridge piers whose failure mode is complex shear-flexure mode. Full scaled RC pier models whose aspect ratio is about 2.67 were constructed and quasi static test according to the drift level history was implemented. From the test results, effect of the lap splices on the seismic performance of bridges piers was analyzed, and the seismic capacity of the model bridges was evaluated by capacity spectrum method.

Purpose : The purpose of this study was to identify the effect of recovery of disability on post-stroke depression in stroke patients. Methods : Fifty patients with stroke were participated in this study. The stroke impact scale(SIS) was used to assess the recovery of disability according to stroke and short form of geriatric depression scale(SGDS) was used to assess the poststroke depression(PSD). Results : The suspicious for depression were exhibited in 38%(n=19) and patients with depression were 58% (n=26) of 50 patients with stroke. In correlation between recovery of disability and depression, emotion and recovery of stroke negatively correlated with depression(p<.05). Conclusion : These results demonstrates that patients with stroke need to manage and treat emotion for the prevention and management of PSD.

In this paper, the critical buckling temperature of single-walled Boron Nitride nanotube (SWBNNT) is estimated using a new nonlocal first-order shear deformation beam theory. The present model is capable of capturing both small scale effect and transverse shear deformation effects of SWBNNT and is based on assumption that the inplane and transverse displacements consist of bending and shear components, in which the bending components do not contribute toward shear forces and, likewise, the shear components do not contribute toward bending moments. Results indicate the importance of the small scale effects in the thermal buckling analysis of Boron Nitride nanotube.

This purpose of this study was to understand how organizational communication affects organizational conflict and commitment. This study was based on a questionnaire survey of 238 teachers working in kindergartens and childcare centers in all parts of Korea except Jeju-do. This research used the following tools: the organizational communication scale, the organizational conflict scale, and the organizational commitment scale. The results were as follows: First, satisfaction with organizational communication showed statistically significant effects(${\beta}$ = -.529, p < .001) on organizational conflict. Secondly, organizational conflict had a negative correlation(${\beta}$ = -.398, p < .001) with organizational competence. Third, organizational conflict had a moderating effect between organizational communication satisfaction and the organizational commitment. Fourth, communication satisfaction had a moderating effect between organizational conflict and organizational commitment.

When the hydrodynamic coefficients of the ship maneuvering equation are estimated by captive model test, it is difficult to take account of the scale effect between model and full scale ship. This scale effect problem can be overcome by processing the sea trial data with system identification. Extended Kalman filter is used as a system identification technique for the modification of the simulation equation as well as the estimation of hydrodynamic coefficients. The phenomena of simultaneous drifting of linear coefficients occur. It is confirmed that two coefficients in each pair-($Y_v$', $Y_r$' -m' u'), ($N_v$', $N_r$' )-are simultaneously drifting and all 4 coefficients are simultaneously drifting together. Particularly simultaneous drifting of 2 coefficients in each pair is more significant. It is also shown that the simultaneous drifting of 4 coefficients can be reduced by choosing the input data which have the random v'/r' curve and 4 coefficients are estimated within 2-4% error, which may be noise level. So, it is recommended to operate the rudder randomly in sea trial or model test for the application of system identification technique.

Flow velocity was measured using a hot wire anemometer. Turbulence intensity was in proportion to mean flow velocity regardless of swirl velocity. And integral length scale has proportional relation with swirl velocity regardless of measurement position. Flame speed calculated by radius of visualized flame was increased and then decreased according to lapse of time from spark. Maximum flame speed was increased according to increase of turbulence intensity. Burning speed and flame transport effect increased with increase of swirl velocity, but ratio of burning speed to flame speed decreased with increased of swirl velocity. Mass fraction burned versus volume fraction burned was increased in proportion to the increase of turbulence intensity, caused by increase of combustion promotion effect according to increase of turbulence intensity and scale.

A Linear Approximated Inverse Almost Ideal Demand System, suggested by Eales and Unnevehr, is estimated with monthly data set of Korean fruits consumption. LA/IAIDS consists of 6 demand equations which correspond to domestically produced Hanrabong, overwintering mandarin, strawberry, melon and tomato with imported orange. The results indicate that price and scale flexibilities are negative, as expected. And the significance is that a 10% increase in imported orange quantity is associated with 5.5% declines in the price of Korean Hanrabong while the price of other fruits is minimally affected. In addition, the estimate of scale flexibility of Hanrabong (-2.96) is much smaller than any other fruit. Hanrabong farmer might be in the face of deficit operation as a consequence of the substitution effect if orange would be imported in accordance with the Korea-U.S. free trade agreement.
