This study is a meta-analytic review on the studies of health belief model(HBM) in Korea, which is a socio-cognitive theory of decision making to individual health-related behaviors. From a database of 54 independent studies published in major academic journals in Korea up to the end of 2013, the HBM accounted for 24.5% and 25.0% of the variance in health behavior and behavioral intention, respectively. The results showed that both health behavior and behavioral intention were positively associated with all variables of HBM (perceived susceptibility, perceived severity, perceived benefits, and self-efficacy) except for perceived barriers. Although the effect size of perceived barriers was not statistically significant, it was negatively associated with both health behavior and behavioral intention. The largest effect size was found in the relationship with self-efficacy, and other variables of HBM showed relatively low effect size. Since the analysis indicated the heterogeneity of the results, subsequent analyses were performed to test moderating effects of behavioral type (screening, preventive behavior, sick role behavior), measurement, and subjects of study. Overall, these findings provide an empirical evidence that HBM is still a useful model to explain and predict individuals’ health related behavior although the magnitudes of its effect sizes was relatively low. With the implications and limitations of the meta-analytic review, the directions of future research were discussed.

본 연구에서는 유기농자재인 키토산, 목초액 및 EM 활성액 등을 공시재료로, 배추 정식 전에 100배액 토양관주 처리하고, 배추 정식 후 15일 간격으로 엽면살포 농도를 100배액과 1,000배액으로 3회 엽면살포한 후 배추의 생육 및 토양 미생물상의 변화에 대해 분석하였다. 유기농자재 처리에 따른 배추의 생육특성은 대조구에 비해 유기농자재 처리구에서 생육이 양호하게 나타났으며, 유기농자재 간에는 키토산 처리구에서 양호하였고, 특히 키토산 1,000배액 처리구에서 생육이 양호하였으며, 주중이 5.60 ㎏으로 가장 무거웠다. 유기농자재 처리에 따른 토양 미생물상 변화는 대조구에 비해 유기농자재 처리구에서 세균, 트리코데마 및 방선균수은 증가한 경향을 보였고, 사상균수는 약간 감소한 경향을 보였으나 처리간 일정한 경향은 없었다. 유기농처리구 간에는 키토산 1,000 배액 처리구에서 세균, 트리코데마 및 방선균수가 가장 많이 증가하였다. This study was conducted to investigate the effects of organic materials, chitosan, wood vinegar, and EM active solution, on soil microbial and growth in Chinese cabbage. The organic materials were treated with chitosan, wood vinegar, and EM (effective microoganism) active solution, and the treatment concentration was 100 times solution and 1,000 times solution level with foliar application. The results are summarized as follows: Among foliar application of organic materials treatment plot[?], with 1,000 times solution level of chitosan was effective in inhibiting microbial growth in Chinese cabbage compared to other plots and control. The microorganism number in the soil for cultivation of Chinese cabbage increased with organic materials treatment plot as compared with control. Especially, 1,000 times solution level of chitosan showed the most significant effect.

Separation of fructose and glucose from fructose corn syrup has been one of the most difficult and most important separation processes now in commercial practice. In this study we used cycling zone adsorption. The experiment was performed on a standing mode where the cold and hot temperatures were 5℃ and 50℃ respectively. The outlet concentration of glucose was nearly independent of temperature while that of fructose increased with the increase of temperature. Thus by changing the temperature of the bed periodically, the separation was attained. Flow rate swing decreased the separation factor and the diluting feed solution increased the separation factor. The degree of separation was represented in terms of flow rate and cycle time. The maximum separation factor was achieved when the retention time and half cycle coincided.
