아버지의 음주실태와 관련하여 문제음주군과 정상음주군을 조사하고, 로지스틱 회귀분석을 통해 문제음주를 유의미하게 예측할 수 있는 개인 적 특성, 가족관계 특성, 사회경제적 특성 요인을 분석하였다. 이를 위해 30-50대 아버지 149명을 대상으로 온라인 설문조사를 실행하였으며, 연 구의 목적과 활용방안 등에 대해 설명하고 연구에 대한 동의를 얻은 이 후 조사하였다. 아버지의 문제음주를 유의미하게 예측하는 개인적 특성 은 ‘자아존중감’이었고, 가족관계 특성은 ‘배우자의 정서적 지지와 도움’ 이었다. 아버지의 사회경제적 특성은 문제음주와 관련하여 유의미한 예 측변수가 아닌 것으로 나타났다. 연구 결과를 바탕으로 아버지 대상의 문제음주 개입상담 및 교육 프로그램 등에서 중점을 두어야 할 활동 내 용을 제안하였다.

This study is to establish optimizing condition of alcohol fermentation in vinegar production with aronia, to confirm whether this can be industrially used, and to compare and analyze a change in anti-oxidative activity and quality characteristic according to alcohol fermentation of aronia. The optimized conditions for alcohol fermentation were as follows: Saccharomyces cerevisiae 5645 of yeast strain, a 5% inoculum size, aronia juice with a brix value of 14, and a glucose content of 7%. As a result to conduct scale up with optimizing conditions of alcohol fermentation of aronia, 8 days (192 hrs) of total alcohol fermentation time and 7.4% of the final alcohol content. The harvest volume accounted for approximately 90.2% with a loss of about 2.8%. As a result of antioxidant test, anti-oxidative activity of alcohol fermented liquor is lower than anti-oxidative activity of aronia extract, because of the decrease of antioxidant by oxidation of the fermentation process. However, the decrease of tannin by the fermentation process reduces acerbity of aronia, so increases overall preference

본 연구에서는 PVA(Poly Vinyl Alcohol)섬유와 GO(Graphene Oxide)를 혼입한 섬유보강 콘크리트(FRC)의 역학적 특성 을 평가하고자 하였다. GO와 PVA 섬유를 동시에 혼입한 FRC 각각의 재료를 단일로 사용하였을 때보다 기대효과가 다소 미흡 하였지만, 각 재료의 하이브리드화로 인장강도가 개선되면서 PVA 섬유 혼입률 0.1∼0.3%과 GO 혼입률 0.025%에서 우수한 효 과를 얻을 수 있었다. 특히 PVA 섬유는 0.3%로 혼합하였을 때 부작용을 최소화하면서 최대의 효과를 보였지만, 적절한 GO 배 합비를 조절할 필요가 있으며 FRC내 GO와 PVA 섬유의 최적배합을 구하기 위한 추가적인 연구가 필요할 것으로 사료된다.

With the history of more than 2,200 years, Yibin is one of the national historical and cultural cities named by The State Council of China. As an important alcohol production base, Yibin city has a long history of alcohol brewing. Its brewing industry products are not only well-known in China, but also sold to various countries around the world. Yibin is currently responding to China's 14th Five-Year Plan, promoting urban construction with cultural construction and developing the alcohol industry ,and trying to build an ecological new area in the upper reaches of the Yangtze River to become an “economic sub-center” in Sichuan province. The construction of Yibin city and the development of alcohol industry are intertwined together, and the development process of alcohol industry has an important influence on the urban construction of Yibin, especially in the cultural city construction. In this study, we used literature analysis to investigate the influence of alcohol industry to the construction of Yibin cultural city. Based on the degree of correlation between development elements of Yibin cultural city and alcohol industry, we believe that the alcohol industry mainly has changed the appearance and layout of the cultural landscape, and influenced the urban surrounding construction and distribution structure. What’s more, alcohol industry has enriched the life of Yibin people, and made the urban culture more colorful. Last but not least, the alcohol industry also has provided Yibin with unique tourism cultural resources, which promotes the development of Yibin’s tourism culture.

Low alcohol (6%) wines were manufactured using Campbell Early. To develop the sterilization process of low alcohol wines, red wines were heat sterilized, and rose wines were nonthermal sterilized by concentration using potassium metasulfite and potassium sorbate. Samples were stored at 25℃ and quality characteristics were investigated by period. Results of this study revealed the pH of the samples after sterilization ranged from 3.15 to 3.19, and the total acidity of wines ranged from 0.011 to 0.024%. The free SO2 contents of wines ranged from 13.00 to 29.678 mg/L, and the total SO2 contents of wines ranged from 47.50 to 121.00 mg/L. L (lightness) of wines decreased whereas a (redness) and b(yellowness) increased. The hue value of wines ranged from 0.52 to 1.03, and decreased significantly(not including rose sweet wines). The color intensity of red and rose dry wines after sterilization increased, whereas red and rose sweet wines decreased. The DPPH radical scavenging activity of red wines and rose wines ranged between 75.50 to 89.23%, and 36.60 to 56.54%, respectively. The total polyphenol contents were 57.51~182.63 mg%. Results of this study provide scientific information to establish the sterilization process of low alcohol wines.

Wide-area surface decontamination is essential in the emergency situation of release of radioisotopes to public such as nuclear accident or terrorist attack. Here, a self-generated hydrogel based on the reversible complex between poly (vinyl alcohol) (PVA) and phenylboronic acid-grafted poly (methyl vinyl ether-alt-mono-sodium maleate) (PBA-g-PVM-SM) was developed to remove the radioactive cesium from surface. Two aqueous polymeric solutions of PVA and PBA-g-PVM-SM containing sulfur-zeolite were simultaneously applied to surfaces, which subsequently self-generated a hydrogel based on the PBA-diol ester bond. The sulfur-zeolite suspended in hydrogel selectively remove the 137Cs from contaminated surface and easily separated from the dissociable used hydrogel by simple water rinsing. In radioactive tests, the resulting hydrogel containing sulfur-chabazite displayed high 137Cs removal efficiencies of 96.996% for painted cement and 63.404% for cement, which was 2.33 times higher than that of commercial strippable coating (Decongel). Considering the intrinsic various ion-exchange ability of zeolite, our hydrogel system has the excellent potential for the effective removal of various hazardous contamination including radionuclides from the surface.

Purpose: This study to provide the basic data necessary for developing support policies and intervention programs through an in-depth and integrated exploration of the experiences in the of recovery and social adaptation through therapeutic community of male homeless alcohol dependents. Methods: Data were collected from two participants through an in-depth interviews and were analyzed the life history research suggested by Mandelbaum (1973). This analysis was conducted the perspectives of the life domain, turning point, and adaptation, which are three structured analysis frameworks, beyond the continuity of chronological life history. Results: The results were the dimensions of life that led to alcoholism, turning point where life changed, and adaptation to live for self-realization with new life values while maintaining sobriety. Its content includes the adaptation process. Conclusion: Follow-up studies and activities for an integrated support policy and intervention program should be conducted by reflecting on the problems and intervention strategies raised above.

The synthesis of porous W by freeze-casting and vacuum drying is investigated. Ball-milled WO3 powders and tert-butyl alcohol were used as the starting materials. The tert-butyl alcohol slurry is frozen at –25oC and dried under vacuum at –25 and –10oC. The dried bodies are hydrogen-reduced at 800oC and sintered at 1000oC. The XRD analysis shows that WO3 is completely reduced to W without any reaction phases. SEM observations reveal that the struts and pores aligned in the tert-butyl alcohol growth direction, and the change in the powder content and drying temperature affects the pore structure. Furthermore, the struts of the porous body fabricated under vacuum are thinner than those fabricated under atmospheric pressure. This behavior is explained by the growth mechanism of tert-butyl alcohol and rearrangement of the powders during solidification. These results suggest that the pore structure of a porous body can be controlled by the powder content, drying temperature, and pressure.

본 연구에서는 유화안정제 중 하나인 cetyl alcohol 함량에 따른 천연 염모제 헤나의 유화 안정성을 분석하고 가장 안정한 유화를 나타내는 cetyl alcohol 함량을 확인하였다. 유화 안정성을 분석하기 위해 cetyl alcohol의 함량에 따른 입자 크기, 입자 형태, 점도 및 염색 후 색상의 차이를 비교하였다. Dynamic light scattering (DLS) zeta 분석 결과, cetyl alcohol 3 %가 zeta potential 값이 115.9 mV로 가장 높은 값을 보였으며, 입자크기분포는 cetyl alcohol의 함량이 3 %인 크림 제형 염모제가 증류수에 분산된 헤나와 비교해 입도분포의 폭이 좁았다. 점도계 분석 결과 cetyl alcohol의 함량이 증가할수록 점도가 증가하였고, 크림 제형의 헤나 pH 측정 결과 두피에 적합한 pH 범위로 측정되었다. 또한 헤나 크림 제형 염모제에서는 cetyl alcohol의 함량이 증가할수록 유화 안정성이 증가하였다.
