봉사활동의 단순한 참여 유도를 넘어, 봉사 참여자가 실제 봉사활동경험을 긍정적으로 받아들이고 인식하게 하는 요인에 대한 이해가 필요하다. 본 연구에서는 대학생이 봉사활동 참여 중 현장에서 지각한 관계자들로부터의 사회적 지지(정서적 지지, 정보적 지지, 평가적 지지)가 봉사참여 정도와 봉사에 대한 긍정적 참여태도 간 관계에서 갖는 조절효과를 확인하고자 하였다. 이를 위해 봉사활동 참여 경험이 있는 서울, 경북, 충북, 충남, 인천 소재 대학교 학생 185명을 대상으로 설문을 실시하였다. 회귀분석 결과, 봉사관계자가 보이는 정서적 지지가 높은 경우, 대학생의 봉사활동 참여 정도와 봉사활동에 대한 긍정적 태도가 정적인 관계를 가지는 것으로 나타났다. 반면, 봉사관계자의 평가적 지지를 높게 지각한 경우는 낮게 지각한 경우에 비해 항상 높은 수준의 봉사태도를 가졌으며, 봉사관계자의 정보적 지지는 대학생의 봉사활동 태도와 유의한 관계를 가지지 않았다. 이러한 연구결과는 지지의 내용에 따라 그 영향이 달라지며, 봉사활동을 하며 마주하는 봉사관계자들이 제공하는 사회적 지지가 그 종류에 따라 봉사활동참여에 따른 봉사태도 함양 정도를 다르게 조절할 수 있음을 보여준다. This study examined the relation between students’ participation in and attitudes toward volunteering work, and tested whether the relationship was moderated by different social support, (i.e., emotional, informational and appraisal) that participants perceived from their volunteer sites. After the regression analysis on the responses from 185 university students, the results indicate that only when students perceived high emotional social support at their volunteer sites, was the relation between volunteering participation level and attitude positive, meaning a positive relationship was not significant when students perceived low emotional support. Meanwhile, students who perceived high appraisal social support at their volunteer sites always had more positive attitudes toward their volunteering experiences compared to those who perceived low appraisal support. The informational support, however, was not significant in influencing on students’ positive attitudes toward volunteering work. This illustrates how social support from the people they meet while practicing volunteerism can affect the relation between students’ participation in and attitudes toward volunteerism. Furthermore, the finding from this study that there is different moderation effects according to the specific types of social support provides implications that can be reflected in volunteer sites for meaningful, beneficial and long lasting volunteering work. The results align well with symbolic interactionism. In addition to the implications for future practice, discussion points and some limitations of this study were presented along with suggestions for further studies.

Raman spectroscopy provides many advantages compared to other common analytical techniques due to its ability of rapid and accurate identification of unknown specimens as well as simple sample preparation. Here,we described potential of Raman spectroscopic technique as an efficient and high throughput method to detect plants infected by economically important viruses. To enhance the detection sensitivity of Raman measurement,surface enhanced Raman scattering (SERS) was employed. Spectra of extracts from healthy and Turnip yellow mosaic virus (TYMV) infected Chinese cabbage leaves were collected by mixing with gold (Au) nanoparticles. Our result showed that TYMV infected plants could be discriminated from non-infected healthy plants, suggesting the current method described here would be an alternative potential tool to screen virus-infection of plants in fields although it needs more studies to generalize the technique.

This study examined the quality characteristics of waffles made with coconut extract. Waffles were prepared with the substitution of 25, 50, 75, 100, and 125% of coconut extract. The viscosity of the batter tended to increase with increasing ratio of coconut extract, whereas the spreadability measures were not changed significantly. The baking loss rates tended to increase with increasing ratio of coconut extract while the moisture contents were not changed significantly. The L-value and b-value decreased but the a-value increased. TPA showed that the hardness, springiness, chewiness, cohesiveness, and gumminess tend to increase with increasing amount of coconut extract while the resilience was not changed significantly. The results of the sensory evaluation showed that waffles made with 100% coconut extract were the most preferable in appearance, flavor, taste, texture, and overall acceptability.

본 연구에서는 충주댐 유역($6,642.0km^2$)을 대상으로 Terra MODIS (Moderate-Resolution Imaging Spectroradiometer) 위성영상과 SWAT (Soil and Water Assessment Tool) 모형을 이용하여 융설이 댐유입량에 미치는 영향을 분석하였다. SWAT 모형의 융설 매개변수인 적설면적 감소곡선(Snow Cover Depletion Curve; SCDC)을 결정하기 위해 10 sets (2000-2010)의 Terra MODIS 위성영상으로부터 추출한 적설분포도와 지상 강설자료를 이용하여 구축한 적설심분포도(snow depth distribution; SDD)를 도출한 결과, 50% 적설면적일 때의 적설면적감소계수(sno50cov)는 0.4~0.7의 범위를 가지는 것으로 분석되었다. 매년의 융설 매개변수를 적용하여 융설기간 (11~4월)동안의 유출을 보정한 결과 평균 $R^2$는 0.54이었다. 10년 동안 융설기간의 유출량은 평균 104.3 mm로 연 유출량의 12.0%를 차지하는 것으로 분석되었다. This study is to evaluate the snowmelt impact on dam inflow for the Chungju Dam watershed $6,642.0km^2$ using Terra MODIS (Moderate-Resolution Imaging Spectroradiometer) and Soil and Water Assessment Tool (SWAT). To determine the SWAT snowmelt parameter; snow cover depletion curve (SCDC) the snow depth distribution (SDD) using Terra MODIS was used, the snow depth was spatially interpolated using snowfall data of ground meteorological stations. For 10 sets (2000-2010) data during snowmelt period (November-April), the sno50cov parameter, that is, the 50% coverage at a fraction of SCDC which determines the shape of snow depletion process, showed the values of 0.4 to 0.7. The SWAT model was calibrated with average $R^2$ of 0.54 using the sno50cov of each year. The 10 years average streamflow during snowmelt period was 104.3 mm which covers 12.0% of the annual streamflow.
