본 연구를 실시하는 목적은 자기성찰과 정신건강 간에서 나타나는 5요인 마음챙김 경로 및 간접효과유의성을 검증하고자 하는데 있다. 본 연구대상은 익산시와 평택시의 애견훈련센터에 방문하는 성인남녀 140명에게 설문조사를 한 후 표기가 불분명한 자료를 제외한 129명의 자료를 토대로 분석하였다. 분석에 사용된 측정도구로는 자기성찰, 5요인 마음챙김, 정신건강에 관한 설문지였다. 본 연구의 자료분석을 위하여 M-Plus 6.12를 활용해 분석하였다. 본 연구의 매개효과에 대한 결과분석에서 자기성찰은 5요인 마음챙김(β=.358, t=4.187, p <.001)에 유의한 정적 영향을 미치는 것으로 나타났다. 그리고 5요인 마음챙김은 정신건강(β=.264, t=2.445, p <.01) 영향을 미치는 것으로 나타났다. 더불어 간접효과유의성검증결과에서 자기성찰이 5요인 마음챙김을 경유하여 정신건강에 이르는 경로의 경우의 간접효과(β=0.123, CI[0.014 ~ 0.319])는 유의한 것으로 나타났다. 이러한 과정을 통하여 자기성찰과 정신건강과 5요인 마음챙김의 관계성 검증분석을 토대로 한 경로 및 간접효과유의성검증을 확인할 수 있었다

In three studies, we show that semployee accent directly, indirectly (through intelligibility and trust), and/or conditionally affects customer participation (CP) in services positively or negatively, depending on the type of accent and its valence, the customer’s need for interaction, and the type of CP, i.e. voluntary, mandatory, or replaceable CP.

The study investigates the relative effects of two types of indirect written corrective feedback (CF) on the acquisition of English articles. Thirty-five high intermediate Korean EFL college students who were enrolled in three composition classes participated in this study. After the instruction on the English article usage, three classes (Class A, Class B, and Class C) received different types of feedback on their blog writings over the course of a semester. Both Class A and Class B received indirect feedback in the form of underlining errors. In the following class, Class A received correct forms with metalinguistic information for the errors revised incorrectly, but Class B did not have such opportunities. The Class C received no feedback. The results showed that only Class A, which received indirect feedback plus correct forms with metalinguistic information, made a statistically significant gain from the 3 sessions of feedback treatment. Pedagogical implications were provided on the basis of the findings.

본 연구에서는 산림치유인자인 경관과 청각요소를 활용한 산림의 간접적 영향이 기분개선에 미치는 영향을 알아보고 자 하였다. 실험은 신체건강한 대학생 30명(23.6±1.7세)을 대상으로, 2016년 10월 5일부터 11월 30일 까지 약 2달간 실시되었다. 산림과 도시공간의 경관과 소리를 이용하여 3가지 요소(이미지 요소, 소리 요소 그리고 이미지+소리 요소)를 만들었으며, 대상자들이 실내에서 이 3가지 요소들을 감상하였다. 그리고 3가지 요소들이 기분개선에 미치는 영향들을 SPSS 18.0프로그램을 이용하여 비교분석하였다. 기분개선을 측정하기 위한 심리검사로써 기분상태검사 (POMS)와 의미분별법(SD)이 사용되었다. 그 결과 간접적인 산림의 자극은 긴장, 피로, 분노, 혼란, 우울감을 억제하고 활력감을 증진시키는 효과를 나타내었고 산림의 자극 간 비교에서는 차이를 보지 않았으나 도시의 자극에 비해 산림의 자극이 쾌적감과 자연감 그리고 진정감을 높이는 효과를 가지는 것으로 나타났다.

Biodiesel fuel (BDF) can be effectively used as an alternative fuel in diesel engines. The BDF, however, may affect performance and exhaust emissions of the diesel engine because it's physical and chemical properties are different with from the diesel fuel such as viscosity, compressibility and so on. To investigate an effect of injection timing on characteristics of performance and exhaust emissions with the BDF in an IDI diesel engine, this research applied the BDF derived from soybean oil in this study. The engine was operated with six different injection timings from TDC to BTDC 12 ˚CA and six different loads at the engine speed of 1500 and 2000 rpm. In less then the BDF 20, it showed the similar trend compare to the diesel fuel. But, the best injection timing was 2˚CA retarded compare to the diesel fuel with BDF 50.

Bioenergetics has been defined as the biology of energy transformations and energy exchanges within and between living organisms and their environment; this field now includes the concept of bioenergetic medicine, e.g., therapeutic approaches involving biophotons. QELBY® powder is a patented quantum energy-radiating material (patent No. 10-1172018), to be precise, a biologically active silicon dioxide-containing mineral powder that radiates reductive energy in infrared wavelength. In this study, we examined possible biological effects of indirect contact with QELBY® powder on various mammalian cell lines derived from macrophagic (MØ) and nonmacrophagic cells, including Raw 264.7 (mouse-derived MØ cell line), HD11 (chicken-derived MØ cell line), and HeLa (human cervical cancer cell line). Our comparison among the cells with and without indirect contact with QELBY® powder showed that this indirect contact significantly (i) increased the mitochondrial membrane potential (up to 1.36-fold) regardless of the cell type (p < 0.05), (ii) decreased the intracellular concentration of ATP in HeLa cells but not in the MØ-derived cells (p < 0.05), and (iii) protected DNA from damage during oxidative stress according to a standard comet assay (single-cell alkaline gel electrophoresis). Taken together, these results imply that indirect contact with QELBY® powder can make cells more metabolically active by increasing the mitochondrial membrane potential and by alleviating DNA damage caused by oxidative stress.

A number of heavy rainfall events on the Korean Peninsula are indirectly influenced by tropical cyclones (TCs) when they are located in southeastern China. In this study, a heavy rainfall case in the middle Korean region is selected to examine the influence of typhoon simulation performance on predictability of remote rainfall over Korea as well as direct rainfall over Taiwan. Four different numerical experiments are conducted using Weather Research and Forecasting (WRF) model, toggling on and off two different improvements on typhoon in the model initial condition (IC), which are TC bogussing initialization and dropwindsonde observation data assimilation (DA). The Geophysical Fluid Dynamics Laboratory TC initialization algorithm is implemented to generate the bogused vortex instead of the initial typhoon, while the airborne observation obtained from dropwindsonde is applied by WRF Three-dimensional variational data assimilation. Results show that use of both TC initialization and DA improves predictability of TC track as well as rainfall over Korea and Taiwan. Without any of IC improvement usage, the intensity of TC is underestimated during the simulation. Using TC initialization alone improves simulation of direct rainfall but not of indirect rainfall, while using DA alone has a negative impact on the TC track forecast. This study confirms that the well-suited TC simulation over southeastern China improves remote rainfall predictability over Korea as well as TC direct rainfall over Taiwan.

Objective & Methord : The aim of this study is to examine the effects of indirect moxibustion at the PC6(Naegwan) on normal human beings using power spectrum analysis. Electroencephalogram(EEG) power spectrum exhibits site-specific and state-related differences in various frequency bands. 8 channels EEG study was carried out in 10 subjects(3 females and 2 males). Result : Average value of alpha-wave is decreased significantly in moxa treatment group of real acupoint(PC6) comparing 'before' and 'during' , 'before' and 'after' of the experiment. In non-acupoint(near LU5) group, Average value of alpha-wave is decreased significantly comparing 'during' and 'after'. Alpha value of Both group was decreased according to the degree and the difference is rapid in 'during' - 'after' block. Compare the treat of real acupoint with non-acupoint, there was non significant difference. Conclusion: These results suggested that moxa treatment can revitalize normal human and the influence moxa treatment is more powerful then acupoint-nature. For these reason, usage of substitute moxa for acupuncture is not reasonable.

This study investigates the effects of indirect and direct error feedback on Korean college students’ accuracy improvement in writing and their responses to the feedback they received. The 32 participants of the study were divided into four groups of different error feedback conditions: indirect feedback, indirect feedback along with metalinguistic feedback, direct feedback, and direct feedback along with metalinguistic feedback. Direct feedback was full, explicit error correction, while indirect feedback was coded error correction in which errors were underlined and marked with code. Metalinguistic feedback was marginal explanations about errors. Analysis of error rates in the students’ first and last essay writing did not show statistically significant difference in the accuracy improvement of the four groups. In other words, indirect error feedback was not more effective than direct feedback. However, the gain score in each group showed that indirect feedback and direct feedback were more effective when they were combined with metalinguistic feedback. In particular, the students’ learning diary clearly indicated that the students valued error feedback on their writing and that follow-up feedback was crucial in providing indirect error feedback.
