부수게는 찹쌀이 주원료인데 찹쌀의 수침은 다른 가공공정에서 볼 수 없는 장시간 수침을 실시함으로써 이 기간 동안 유기산의 생성을 유도하여 팽화도에 마이너스 영향을 주는 $Ca^{2+}$과 $Mg^{2+}$을 용출시켜 부수게의 팽화력증가를 유도하여 온 특이한 공정으로 이는 부수게 제조공정에서 미생물의 작용을 활용하여 온슬기를 엿볼 수 있다. 또 한가지 특징은 대두의 첨가는 단백질 함량을 증가시키는 의미도 있으나 찹쌀가루를 찔 때 대두에서 유래한 armylase가 전분에 작용하여 건조된 부수게 반대기의 결정화도을 낮게하여 건조 취급중 균열발생을 감소시키는 효과와 찧을 때 점성이 감소하는 효과가 있는 것으로 판단된다. 부수게 제조시 대두를 첨가하는 것은 영양성, 기능성에서 볼 때 우리가 창출한 쌀과 대두의 조화적 이용의 한예가 된다. 부수게는 우리가 흔히 먹고 있는 밥, 떡 죽처럼 상압에서 가수해서 호화한 것이 아니라 호화후 고온(170$^{\circ}C$)에서 팽화하여 다공성구조를 형성시키므로써 밥이나 떡에서 전혀 느낄수 없는 crunchy type의 snack성을 가지는 과자로써의 특성을 가지고 있다. 그 제조공정은 12단계 이상으로 복잡하며 제조원리면에서 볼 때 물리적, 화학적 그리고 미생물학적인 공정이 조화적으로 활용되어 만들어지고 있기 때문에 재현성이 낮은 어려움이 있기도 하다. 대량생산을 위해서는 적합한 기계화와 자동화공정이 선결되어야 하는 데 떡의 높은 점성이 기계화와 자동화에 큰 제한요인으로 남아 있고, 또한 부수게 반대기를 건조하는 동안 반대기의 균열(cracking)을 효과적으로 방지 할 수 있는 건조조건과 방법에 대한 연구가 남아 있다.

본 연구는 수 과학의 과정중심 통합 활동이 유아들의 과학적 탐구능력과 태도에 미치는 영향에 대해 알아보고 현장에서의 효율적인 교수학습 및 환경구성을 마련하는데 연구의 목적을 두고 있다. 연구대상은 전라북도 I시에 위치한 W대학 부속 유치원 만3세 만5세 유아 89명을 대상으로 각 연령별 주제를 선정하여(만3세 유아는 알, 콩, 열매, 과자, 만5세 유아는 공룡, 감자, 물, 그림자, 색깔이라는 주제 선정) 수 과학의 과정중심 통합 활동을 실행하였다. 자료 분석은 SPSS for Windows 프로그램을 이용하여 대응표본 t검증을 실시하였다. 수 과학의 과정중심 통합 활동을 실시한 결과 과학적 탐구 능력과 과학적 태도를 구성하고 있는 각 하위 요인들이 연령별, 성별로 유의한 차이가 있는 것으로 나타났다. 이러한 결과는 수 과학 과정중심 통합 활동이 만3세 5세 유아들에게 긍정적인 영향을 주는 활동임을 시사하고 있다.

Policymakers' active support as well as broadcasting and telecom industries' endeavors seeking new business opportunities speed up the introduction of a new medium called DMB in Korea. Meanwhile, discussions from a critical perspective concerning the policy rationale, cultural and social implications of DMB and policy processes are rather scanty. The discussion of policy rationale focuses upon whether the rationale to introduce DMB is sufficiently valid. The discussion of DMB's cultural and social bearings is concerned with whether the implications of new media and technology are properly considered in policymaking and that of policy processes questions whether the initial conditions of DMB are appropriately structured. This study explores such issues associated with the introduction of DMB in Korea.

The purpose of this study was to develop a leadership competency model for Korean public library directors which could help the progress of public libraries. Complex methods like contents analysis of precedent studies, FGI with high performers, survey to librarians and directors of public libraries which were affiliated to Seoul Metropolitan Government and validation by specialists were used for this study. As a result, a leadership competency model for Korean public library directors which consists of the 19 components was developed and this model can be used as the criteria for improvement of the leadership competencies of Korean public library directors.

The objective of this study was to determine sensory profiles of rice confections. The samples used in this study obtained from Korea (traditional Korea rice snack and local specialty rice snack) and three countries (USA, Japan, and China) were evaluated and compared. The sensory characteristics of five kinds of rice confections were evaluated using a sensory test and were analyzed via quantitative description analysis (QDA), principal component analysis (PCA), and hierarchical cluster analysis (HCA). In the descriptive analysis, 10 trained panelists evaluated sensory characteristics consisting of 19 attributes, and there were significant differences (p<0.05) among the 16 characteristics. For the descriptive data, multivariate analysis of variance was carried out and identified differences among the samples. The PCA of rice confections for the first two principal components could explain 85.66% of the variations. The Korean, Japanese, and Chinese rice confections were savory, gritty, and particle-sized, the other Korean local specialty rice confections were fruity, sweet, honey-flavored, compact, and crispy, and those from the USA were glossy, grainy, bright, adhesive, cohesive, crispy, and sweet.

The state of carrier-free silver-111 has been studied by applying filtration method. The studies involved that the effects of pH and concentration of silver-111 in aqueous solution have been determined with membrane filters. The present studies revealed that the retainment of silver-111 on membrane filters followed Freundlish adsorption isotherm, and the adsorbed state of silver-111 was present in the form of AgOH. Also it was supposed that the formation of the non-adsorbed hydroxide of$Ag(OH)_{2}-$ may prohibit the existance of AgOH at higher pH, and it seems to be valid that the carrier-free silver-111 in aqueous solution exists in$Ag^+$state.

Objectives: The aim of this paper is to report that herb medicine effects on four infertility patients with ovarian cysts and the menstrual irregularity as a result of ovarian hyperstimulation syndrome. Methods: Four infertility patients with ovarian cysts had the same symptom of menstrual irregularity for preparing In Vitro Fertilization (IVF). They were treated by twice a day herb medication Changbudodam-tang. Then we observed the effects of treatments by regularity of menstruation, checking with ultrasonography of ovarian cyst size. Results: After herb treatments, the sizes of ovarian cysts decreased and one of them disappeared. Above all, menstrual regularity was recovered for preparing IVF. So they could have a positive progress of IVF. Conclusions: These cases show that herb medicine has its effective treatments for the implantational surroundings on infertility patients with ovarian cyst and menstrual irregularity because of ovarian hyperstimulation syndrome.

The purpose of this study was to evaluate the relationship between socioeconomic factors, health behaviors and overweight and to provide information in the policy making process for ensuring health equity. Data of 66,249 adolescents aged 12 to 18 years were derived from the Ninth Korean Youth's Risk Web-based Study, which was conducted in 2013. Multiple logistic regression analysis revealed that overweight were related with gender, parental education, frequency of having breakfast, fruit consumption, vegetable consumption, snack consumption, and frequency of physical activity. Therefore public health programmes should target unhealthy behaviour of adolescents from lower socioeconomic groups to help prevent future life-course disadvantages in terms of health and social inequalities.

Atopic dermatitis (AD) is usually caused by foods such as wheat, egg, milk, and peanuts, leading to common health problems in early childhood with complications like urtication. The aim of this study was to evaluate ethanol extracts of rice and rice snacks concentrated until the ethanol was completely eliminated and hot-air dried. In vitro analyses were carried out using murine macrophage RAW 264.7 cells. We measured cytotoxicity, nitric oxide (NO) production, and inflammatory cytokine level. The NO level of the cells exposed to lipopolysaccharide (LPS) was significantly reduced by rice and rice snack extracts. $TNF-{\alpha}$ level decreased in contrast to the LPS group, although a significant difference was not observed. On the other hand, IL-6 significantly decreased in both rice and rice snack extracts in a dose-dependent manner. The results of the present study suggest that rice and rice snack decreased NO and inflammatory cytokine levels. Therefore, rice could be useful as a raw material for relieving child atopic dermatitis caused by snacks made from wheat.

Objective : To know about ovarian hyperstimulation syndrome pathophysiology, risk factors and clinical features and to research the trend of the study related to OHSS. Methods : We referred a PubMed site by using searching word of "ovarian hyperstimulation syndrome"(Limits: 1 Year, only items with abstracts, Human). Results : 28 journals with 49 papers were searched. Conclusion 1. The study of OHSS subjects on pathophysiology, prevention and medical treatment. 2. As OHSS is an exaggerated response to ovulation induction therapy, it's emphasized that aspect of prevention OHSS. 3. Preventing OHSS are the following. The first is to give a GnRH agonist or antagonist in substitute for hCG. The second is to screen out prevalence of thrombophilia. The third is to monitor $E_2$ levels. The forth is to aspirate of Mediculous follicle. The fifth is cryopreservation of all embryos. The sixth is that administration of albumin for treatment of OHSS. But, it's not useful to administration of albumin for prevention of OHSS. 4. There's no therapy of OHSS. But, there's only symptomatic treatment of OHSS.
