돼지감자 분말로부터 에탄올을 효율적으로 생산하기 위하여 Kluyveromyces marxianus F043을 2% sodium alginate에 고정화시키고 연속발효를 수행하여 발효특성을 조사하였다. 연속발효 수행시 고정화 효모는 48시간으로 활성화되었다. 2% cellulase로 처리된 돼지감자배지의 CSTR 연속발효에서 희석속도가 증가할수록 에탄올 농도는 감소하였고 잔당 농도는 증가하였다. 에탄올 생산성이 높고 당의 유실율이 낮은 최적조건은 희석속도 0.2h^(-1), 유입 배지농도 75 g/ℓ이었으며 이때 에탄올 생산성은 3.1 g/ℓ·h, 기질이용율은 62.6%이었다. 최적조건에서 3주 동안 연속발효를 수행하였을 때 유출액 중의 에탄올 농도는 16.3∼17.9 g/ℓ, 생균수는 6.60∼7.16 log cells/㎖로 거의 일정하게 유지되었고 에탄올 이외에 methyl, n-propyl, iso-butyl, iso-amyl alcohol이 미량 검출되었다. To produce ethanol from Jerusalem artichoke powder efficiently, Kluyveromyces marxianus F043 cells were encapsulated in 2% sodium alginate and were cultured in a countinuous reactor to investigate the fermentation properties. Immobilized K. marxianus F043 cells were activated for 48 hours in a fermentor for continuous ethanol production. The culture in a CSTR using a Jerusalem artichoke substrate treated with 2% cellulase showed a decrease in ethanol concentration and an increase in residual saccharide concentration with a increasing dilution rate. Optimum conditions for high ethanol productivity and low residual saccharide outpu were clarified to be given at a dilution rate of 0.2 h^(-1) and a Jerusalem artichoke medium concentration of 75 g/ℓ. Ethanol productivity of 3.1 g/ℓ·h and saccharide utilization of 62.6% were obtained under the optimum condition. When the fermentation was performed for 3 weeks under these conditions, the effluent medium showed stable ethanol concentrations of 16.3∼17.9 g/ℓ and viable cells of 6.60∼7.16 log cells/㎖ without contamination. Trace amounts of methyl, n-propyl, iso-butyl, iso-amyl alcohols besides ethanol were detected.

The purpose of the present study is to investigate the effects of cognitive processing strategies on explicit/implicit memory dissociation and post-traumatic stress symptoms for students in junior high school at Taean disaster site. This study involves sixteen subjects who experienced the oil-spill accident. The control group involves twenty subjects who live in Daejeon and hence did not experience the oil-spill accident. The results indicate that data-driven processing was related to the enhanced implicit memory and explicit memory deficit (memory dissociation) with trauma related cues in the trauma group compared to the non-trauma group. Moreover, data-driven processing increased PTSD severity in the trauma group compared to the non-trauma group, whereas conceptual processing reduced PTSD severity. The results support the viability of the distinction between data-driven/ conceptually-driven processing for the understanding of memory quality and the development of PTSD(Brewin et al., 1996; Conway, 1990; Ehlers & Clark, 2000; Foa et al., 1989). These results were discussed in terms of relevance to the previous studies. And the limitations of the present study were suggested for further study. 본 연구는 외상의 처리수준이 암묵기억의 향상과 외현기억의 결핍이라는 기억의 해리 및 외상 후 스트레스 반응에 어떤 영향을 미치는지를 기억과제 실험 패러다임을 통해 밝히고자 하였다. 연구에는 태안 기름유출 사고 지역의 중학생들 중 총 16명이 실험집단에 참여하였고, 대전시에 위치한 중학교 학생 중 총 20명이 통제집단에 참여하였다. 연구 결과, 외상을 경험한 집단은 외상을 경험하지 않은 집단에 비해 외상관련 자극을 자료주도적으로 처리할 때 개념주도적으로 처리할 때보다 높은 기억의 해리 현상을 보였으며, 외상을 경험한 집단이 외상관련 자극을 개념주도적으로 처리하면, 일정시간이 경과한 후에 외상후 스트레스 증상이 감소하였다. 이러한 결과는, 외상의 정교화 과정이 병리적인 기억패턴의 형성이나 외상후스트레스 증상의 발달을 예방하고 감소시키는데 중요한 역할을 함을 의미하는 것이다. 마지막으로 본 연구의 한계와 의의를 논의하였다.

The purpose of this study is to investigate the mediating effect of self-esteem between child maltreatment(i.e. child abuse, child neglect) and social withdrawal. Especially, by setting the self-esteem that is considered important in childhood as a mediating variable, this research aims to reveal the effects of the child neglect and abuse on children’s social withdrawal. For the empirical analysis, a structural equation model analysis was performed applying the 7th (2016) data executed for Year 1 elementary school students during the Korean Children and Youth Panel Survey (KCYPS) published by the National Youth Policy Institute (NYPI). The results showed (1) the direct effect of child abuse on self-esteem but not on social withdrawal, (2) the direct effect of child neglect on self-esteem and social withdrawal (3) indirect effect of child abuse on social withdrawal mediated by self-esteem was statistically significant, (4) indirect effect of child neglect on social withdrawal mediated by self-esteem was statistically significant. Hence, it can be seen that self-esteem is a mediating variables between child neglect and social withdrawal. Through the above research results, implications regarding Korea's child abuse policy was proposed and the proposal for future research direction was additionally discussed. 본 연구는 부모의 학대와 방임이 각각 자아존중감을 통해 사회적 위축에 어떠한 영향을 미치는지 그 인과관계를 검증하는데 주된 목적이 있다. 이를 위해 한국청소년정책연구원의 한국아동청소년 초1(2010년)패널 중 최근 3개년도 데이터 5차(2014년, 초5)에서 7차(2016년, 중1) 설문에 참여한 2,342명의 청소년 자료를 분석하였다. 주요 통계분석은 구조방정식모형을 활용하였다. 그 결과, 학대는 아동의 사회적 위축에 직접적 영향을 미치지 않는 것으로 나타났다. 그러나 자아존중감을 통해 간접적으로 사회적 위축을 증가시키는 것으로 나타났다. 반면, 방임의 경우는 사회적 위축을 직접적으로 증가시킬 뿐 아니라, 자아존중감을 통해서도 간접적으로 사회적 위축을 증가시키는 것으로 나타났다. 부트스트래핑(Bootstrapping) 검증결과, 이러한 매개효과는 통계적으로 유의한 것으로 나타났다. 이러한 결과를 바탕으로 학대와 방임의 부정적 영향을 감소시키기 위한 사후 개입방안 뿐 아니라 예방적․정책적 방안도 함께 논의하였다.

Objectives: This study reviewed previous studies examining the effect of augmentative and alternative communication (AAC) intervention on expressive language ability, cognitive ability, and quality of life of individuals with dementia to provide effective treatment approaches in clinical settings. Methods: A total of 8 studies on AAC interventions for dementia were selected through a literature search in the database and selection process. To comprehensively analyze the intervention effect sizes reported in the literature, a meta-analysis method was applied, and the effect size Hedges’ g was calculated for each measurement variable. Results: Results showed that the overall effect size of the AAC intervention was g= .864, which was statistically significant and effective at 95% confidence intervals. To be specific, there were significant positive effects on cognitive ability and quality of life. However, the AAC intervention did not have a significant effect on the expressive language ability of individuals with dementia. Conclusion: The meta-analysis method was applied to comprehensively analyze whether AAC intervention had a significant effect on the communication and quality of life of patients with dementia. By reviewing the results of the previous studies, effective AAC interventions in language, cognition, and quality of life of dementia patients were reviewed. Directions for future studies on AAC intervention in dementia were discussed.

As Modern make-up is adopting in to the modern society, it is becoming more complex and diverse. Since 20th century, naturalistic image-driven make up was influenced by the hippie culture. The naturalistic make-up was inspired to save environmental and ecological problems around the world. With the advanced technology, the environmental friendly idea recreated the naturalistic image. Following research analyzes the foundation and transitions in the naturalism. The research also focuses on naturalistic aspects in modern make-up after 2005 through the composition. First, naturalism in the modern make up does not impose strong emphasis or unnatural image. Secondly, naturalistic make-up categorizes the design into color, form and texture. Through dots, lines, and sides, design give more emphasis to sides than lines. Naturalistic make-up depicts the larger eyes, round ball cheeks, and less emphasizes on the eyebrows and lips. The skin tone was used to emphasize the healthy and the lively image of the naturalism. The color of the eye shadows exclude strong primary color and utilized colors that are similar to skin tones, like beige, brown, pastel pink, or orange, to demonstrate the transparent image. Make-up’s form is represented by mat, glossy, pearl, and glitter. Active and lively image was created through glossy form and dry and smooth mat displays light form.

Recently, online consumption has increased sharply due to the decrease in an outing and face-to-face activities due to the spread of COVID-19. Live commerce, a shopping platform with social media, a communication channel for users, is rapidly emerging as a new marketing channel. More and more consumers use a platform where sellers and buyers can communicate through live commerce to obtain detailed product information and conveniently purchase products. Therefore, this study aimed to analyze the effects of the nature of live commerce on consumers' shopping behavior and purchasing intention, targeting women in their 20s and 40s who have purchased cosmetics through live commerce. This study used a questionnaire that includes demographics, the usage of live commerce, shopping behavior, and purchasing intention. A five-point Likert scale was used for the characteristic of live commerce, shopping behavior, and purchasing intention. Five factors were used for the characteristic of live commerce: reliability, information, usefulness, entertainment, and interactivity. Five factors were used for shopping behavior: impulsive, individual, rational, innovative, and conspicuous. The results show that live commerce is an essential variable of shopping behavior and purchase intention. In particular, it was confirmed that the characteristics of live commerce and shopping behavior influence purchasing intention, and purchasing intention is formed by the characteristic of live commerce and shopping behavior. By analyzing the marketing effects of live commerce, this study is expected to be used as primary data for future marketing strategies and follow-up studies for live commerce. .

보육정책의 이론적 논의와 우리의 과제

신지현 한국사회복지지원학회 2005 사회복지지원학회지 Vol.1 No.1

한국에서의 보육정책에 있어서 2005년을 체제를 정비하기 시작한 새로운 원년이라고 일컫는다. 지난 수년간 한국사회에서 확대된 보육시설은 아동보육의 사회적 책임을 인식한 데서 출발한 것이 아니라 빈곤계층을 위한 구빈적 사회복지적 정책이나 기혼 취업여성의 노동력을 동원하려는 인력 정책에 기반하고 있었음을 부정할 수 없을 것이다. 앞으로는 보육에 대한 국가의 기본적 인식이 전환되어 현재의 잔여적 수준에서 벗어나 충분한 예산을 확보하고 지원대상과 범위를 확대해야 한다. 이와 더불어 아동 복지모델에 맞는 프로그램 및 정책개발이 수행되어야 함은 물론이다. 영유아 보육은 지역, 계층에 구애됨이 없이 보호와 교육이 필요한 모든 어린이에게 양질의 서비스를 균등하게 제공하는 방향에서 계획되어야 할 것이다. 이는 보육사업의 발전이 여성의 사회참여 뿐 아니라 아동의 건전한 성당발달, 지역사회를 위해서 반드시 필요한 것이기 때문이다. 우리나라 보육정책이 많은 발전을 하여 지금의 현실까지 왔지만 아직까지는 국가의 노력과 사회의 노력 그리고 보육시설들의 확충이 더욱더 필요한 실정이며, 양적으로나 질적으로 향상되어 공보육의 확대와 강화를 통해 정부와 민간의 상호협력과 역할분담이 필요하다. 교사대 아동비율과 보육교사의 처우개선책을 동시에 해결하는 방안으로 이 결론에서 연구자는 종합병원에서의 간호사의 근뭊도의 변형이랄 수 있는 2교대 근무를 제안하고자 한다. 우리나라 근로자들의 근무상황이 정시퇴근이 힘든만큼 시간연장현 보육형태를 두기보다는 교사의 2교대 근무를 체계화시킴으로써 제도화 할 필요가 있으며 이에 따르는 보수적체계도 함께 연구되어져야한다고 생각한다.
