This systematic review and meta-analysis aimed to determine whether food intake is effective in preventing diseases related to cognitive impairment. We searched English databases namely MEDLINE, PubMed and ScienceDirect from 2000 to May 2020, and Korean databases namely RISS, KISS, and DBPIA from 1990 to May 2020. We divided the data into 15 groups using the food group classification of the Korean Nutrition Society (KNS). The effect size (Cohen's d) was estimated using a random-effect model, and a 95% confidence interval was calculated for each study. We included 17 cross-sectional studies and 7 cohort studies which involved 45,115 participants. As a result of analyzing the subgroups in the Asian population of both sexes, it was observed that grain intake has a protective effect against cognitive impairment. For females, pulses and fish also have a protective role against cognitive impairment. In the case of seaweed, a negative relationship was found with a moderate protective effect against cognitive impairment (Cohen's d:-0.533, 95% CI: -0.939, -0.126; p=0.010) in Korean studies. Dairy products are associated with an increased risk of cognitive impairment in the American and European population but drinking alcohol is associated with a lower impairment risk. These results provide a basis for formulating the dietary guidelines for preventing dementia for each country.

Polyphenol oxidase-catalyzed oxidation of substrates (t-butylcatechol, 4-methylcatechol, chlorogenic acid, caffeic acid and pyrocatechol) were performed in the Ph range 4~8. Co ncentrations of substrate's major oxidation products were monitored by high performance liquid chromatograph. The nature and amounts of products formed were highly pH dependent. They also were ifluenced by kinds of substrates. Major oxidation product of 4-methylcatechol appeared the maxium value at pH 5, them of chlorogenic acid, caffeic acid and pyrocatechol at pH 6.0 and that of t-butylcatechol at pH 5~7. Time-dependent PPO activity was determined at $4^{\circ}C\;and\;30^{\circ}C$. PPO extracted by phosphate buffer containing triton X-114 (t-PPO) was more stable than PPO by phosphate buffer (b-PPO). The result of electrophoresis, at first PPO was showed only a band at 48 kd. After 1~3 days a partial degrade band was appeared in b-PPO and three partial degrade bands in t-PPO. No activity band was appeared in PPOs at $30^{\circ}C$ and b-PPO at $4^{\circ}C$ after 4 days. And a band (37 kDa) in t-PPO was remained finally and disappered. PPO from Perillae leaves has two activity bands at 48 and 37 kDa in previous paper. It was supposed that PPO in the leaves of Perilla frutescens was a protein having one molecular weight as 48 kDa. And 37 kDa protein, relatively proteolysis-resistant, was a proteolyzed form of a major form.

본 연구는 미토콘드리아 DNA (mtDNA) cytochrome B (CYTB)와 NADH dehydrogenase subunit 1 (ND1) 유전자 서열의 다형성을 근거로 제주도 큰발윗수염박쥐 집단의 유전적 집단 구조와 계통 유연관계를 조사하는 데 목적이 있다. 동아시아 박쥐에서 CYTB 유전자 haplotype은 14개의 haplotype들이 발견되었고, ND1은 9개의 haplotype들이 발견되었다. 집단별 haplotype의 분포는 지역-특이적인 양상을 보였다. ND1 haplotype 분석결과에서 제주도 집단은 4개의 haplotype을 나타내고, 한라산 소집단과 서부지역 소집단은 3개 haplotype을 나타내었으나, 동부지역 소집단에서는 제주도 전체에서 공통으로 발견되는 1개(Nd03)의 haplotype만 출현하였다. NJ tree에서 제주도 집단은 강원도 집단보다 일본 집단과 더 근연으로 확인되었다. 중국과 일본의 모계선조 계보 사이의 분화 시점은 0.789±0.063 MYBP으로 추정되었고, 제주도와 일본의 모계선조는 약 17만 년(0.168±0.013 MYBP) 전에 분리된 것으로 판단된다. 제주도 집단은 적어도 5만 년 이전에 이주한 것으로 보인다. 또한 ND1 haplotype 분석결과는 제주도 집단이 이주 후에도 지역 내에서의 적어도 2회 이상의 유전적 분화를 겪었다는 것을 보여주고 있다. 본 연구결과는 동아시아 큰발윗수염박쥐의 계통 유연관계를 이해하는 데 중요한 기초자료가 될 것이며, 향후 한반도의 남부와 중국, 러시아 등에서 시료 확보를 통해 집단 간 진화적 상관관계를 이해하는 데 필요한 설득력 있는 자료가 마련되어야 할 것이다. This study was carried out to reveal the genetic population structure of the Jeju Island population and the phylogenetic relationship of East Asian populations of the large-footed bat (Myotis macrodactylus) based on the genetic polymorphisms of mitochondrial cytochrome B (CYTB) and NADH dehydrogenase subunit 1 (ND1) gene sequences. A total of fourteen and nine haplotypes were found in the CYTB and ND1 sequences from East Asian bats, respectively. Haplotype distribution showed locality specific patterns. The results from ND1 haplotype analysis showed that the Jeju Island population has four haplotypes: the Mt. Halla and Western subpopulations have three ND1 haplotypes, but the Eastern subpopulation has just a single haplotype Nd03, which is commonly found on this island. The neighbor-joining (NJ) tree showed the closer relationship between Jeju Island and Japan rather than that between Jeju and Gangwon-do Province. The divergence time between the maternal ancestor lineages of Japanese and Chinese populations was estimated to be 0.789±0.063 MYBP. The secondary divergence between Jeju and Japanese bats was calculated about to be 0.168±0.013 MYBP. The Jeju population has immigrated to the island at least fifty thousand years ago. In addition, ND1 haplotype analysis suggested that the insular bats have experienced at least two further genetic differentiation events within this island. Consequently, these findings suggested that the results of this study may play a critical role in understanding the phylogenetic relationship among East Asian bat populations of M. macrodactylus. To prepare more explainable information on evolutionary correlation, analysis is still required to examine using expanded samples from China, Russia, and southern parts of the Korean Peninsula.

신장 위구르무슬림 분리주의운동의 원인분석 연구

김유경 ( Yoo Kyung Kim ) 한국외국어대학교 중동연구소 2010 중동연구 Vol.29 No.2

Though the region of China known today as the Xinjiang Uyghur Autonomous Region has always been troubled, China has several reasons to retain the troublesome province. Xinjiang is important to China politically, economically, and strategically. China also wants to maintain hold of Xinjiang, fearing its loss would incite the secession of Taiwan and Tibet. For these reasons, Chinese government has set up a priority in developing economy in Xinjiang to rein in Muslim separatists. Chinese authorities often resort to heavy-handed suppression to the actions of nationalist separatism and religious extremism. The Xinjiang Uyghur Muslims, however, have mounted major riots and a series of bus bombings have taken in Xinjiang. The main driving force behind the riots is the East Turkistan independence movement. Historically the native population in Xinjiang have resisted Chinese dominance and inspired anti-Han riots from time to time. The conflict in this region has had several causes; the system of `regional autonomy` operating in Xinjiang must be seen as a principal source of the unrest. The pattern of economic development in Xinjiang has ensured the further stratification of the labor market, a stratification that is often blamed for aggravating inter-group friction and the gap between the rich and the poor. This paper analyzes the intrinsic sources of Uyghur discontent and ethno-national conflict in Xinjiang. To support this thesis, the paper presents a historical analysis of the dispute process in Xinjiang and examines the problem from various aspects-politics, economy, ethnicity and religion.

은염과 디지털 도구에 따른 조명비 교육의 실제 적용에 관한 연구

김유경 ( Yoo Kyung Kim ) 한국사진학회 2010 AURA Vol.0 No.22

Photographers deal with light in the limited area of visible ray and the difference in techniques to treat the given light makes difference in works of them. They sometimes have to determine the directions, angles, colors, and quality of light. Also, they know there is lighting ratio in any light that reaches subjects in any situation. The most difficult part of taking pictures in digital environment is that the rule of lighting ratio appled when using silver halide(film) to create the desirable mood is not adequate. Thus, I reviewed a thesis on this part as a preliminary study and found out that when the ratio of highlight and shadow are 1:1, 1:2, 1:4 the results of silver halide were nearly similar with those of digital but the depth of shadow of digital turned out to be opposite in case of 1:8, 1:16, 1:32. In case of digital, I could get results of lighting ratio learned in silver halide only when l took pictures with sequentially reduced light intensity of fill light so that it might be less than the value of lighting ratio indicated on exposure meter, comparing to silver halide. Therefore, this study intends to review the phenomenon and value of education appeared when the results of preliminary study were applied to lighting education. The education was implemented, divided into two groups; one group that experienced the results from the process of comparison experiment of silver halide and digital in real education were different and the other group that didn`t. In addition, I intended to understand the difference in representation properties of silver halide and digital and present the necessity of differentiated and proper approach toward lighting ratio education by analyzing results through questionnaire survey.

본 연구는 대한민국 국가 브랜드 슬로건인 ‘Dynamic Korea’가 지니는 의미와 국가 정체성과의 관계를 개념적으로 살펴보았다. 그동안 국가 브랜드 슬로건의 타당성에 대한 많은 문제제기들이 이루어져 왔는데, 이는 국가 정체성에 대한 논의를 생략한 채, Dynamic이라는 슬로건에 대한 표면적인 의미에 대해서만 주목하였기 때문이라고 할 수 있다. 따라서 본 연구에서는 국가 정체성 개념에 대하여 이론적으로 고찰한 후, 한국의 ‘Dynamism’에 대하여 다각적으로 살펴보았다. 이를 통해 국가 브랜드 정체성 및 슬로건으로서의 ‘Dynamic Korea’가 가지는 의미를 개념적으로 구성하였다. This study aimed to explore the concept of Dynamic Korea, its brand slogan, and its relations to the country identity. There were many debates over the validity of Dynamic Korea as the country brand slogan. However, most of them had mainly been focused on the superficial meaning of the slogan without considering what is the Korea`s country identity. The concept of the country identity was reviewed and dynamism of Korea was inquired in the philosophical and historical aspects. Dynamic Korea is a future-oriented slogan based on its traditions and characteristics. It represents the harmony of calmness and dynamism. It symbolizes the aspiration of the Korean people to further develop their limitless passion and energy and take their place on the world stage.

The purpose of this study is to develop childcare service program through the analysis of the market and the needs of current users. For the purpose of this study, qualitative data were collected by use of an in-depth interview with staffs of Healthy Family-Support Center and outside experts. In addition, information about the chilldcare service market was analyzed. At present, a lot of childcare services are offered by both government sector and private sector institutions, but there is both an overlapping and a gap in the services offered. Based on our data, childcare service was suggested for dual income families with elementary school children. And the curriculum to train individuals for this childcarer service program was developed. The curriculum`s focus was to nurture them to offer more specialized and custom-tailored services.

본 연구에서는 대안시장으로서의 온라인상에서 브랜드 구축을 위해 필수적인 브랜드 이미지를 보다 본질적인 차원에서 관찰하고 오프라인의 확장적 개념으로서 차별적 특성에 대해 논의하였다. 이를 위해 온라인에서의 브랜드, 즉 eBrand의 이미지 차원을 구조화하여 브랜드 구축의 기본체계로 설정 하였다. 또한 온라인 환경에서 브랜드에 대한 전반적 인상을 결정하는 주요한 요인으로 소비자 경험의 역할을 고려하여 이러한 경험적 요인이 eBrand 의 이미지 형성과 어떠한 상호관련성올 가지는가에 대해 규명하고자 하였다. 본 연구는 eBrand의 관점별 이미지를 중심으로 각 하위 이미지에 대한 연상을 유발할 수 있는 단서들을 웹사이트의 구성요소에서 추출하여 이를 유형화하고자 하였다. 본 연구에서는 eBrand의 이미지 형성에 미치는 브랜드 경험요인의 영향관계를 규명하고 아울러 웹사이트 유형을 통제변인으로 보았다. 이는 eBrand 유형에 따른 이미지 차원의 변화를 살펴보고자 함이었다. 본 연구는 경기ㆍ서울 일원의 대학생 283명을 편의적으로 표집하여 12개의 브랜드를 연구목적에 맞게 선정, 통제변인별로 나누어 설문조사를 하였다. 온라인상에서의 브랜드 이미지 목록을 사전조사를 통해 수정ㆍ보완한 후 16개의 이미지 목록으로 확정하여 요인화 과정에 활용하였다. 경험요인 또한 온라인상에서 브랜드 이미지를 형성하는데 영향을 미치는 주요 요인으로 상정하여 웹사이트의 유형별로 다양하게 나타나는 이미지 차원을 도출하였다. 이밖에 본 연구는 이들이 주는 의마와 시사점에 대해 논하였다. This study was intended to not only examine dimensional perspectives of image of click & click brands, so-called, eBrands. but effects of customer experiences as involving variables. First of all, this study tried to focus on how people perceive the types of brand image on the internet. Especially, these dimensions were compared with those of brand images evolved in off-line environment. Types of brand associations and their properties were thoroughly reviewed with the emphasis of main consequences of existing literatures, culminating in revealing the independent predictable dimensions. Assuming that internet is the best environment influencing upon evoking the typology of ebrand image, this study adopted the concept of experience as crucial influencing factor to determine the degree of relevances and associations of sub-concepts under experience. In so doing, this study conducted survey with self-administered questionnaire on 283 college students living around Seoul and its adjacent area. Types of 12 ebrands or websites were classified into four different category such as type of information contents, entertainment contents, community, transaction and so on, under which were individually operationalized as measurable questions to group into some significant factors or dimensions. 5 sub-concepts under experience were borrowed from Bernd Schmitt's aboriginal inventories. Their significances and implications were also discussed.

This study was conducted to reduce children`s fat intake and to establish healthy dietary lifestyles. To achieve these goals, we searched, collected, and analyzed the materials related to the fat education, based on which the research personnel-professors and graduate students in nutrition and child education and elementary school teachers- discussed to figure out major topics, objectives, and detailed contents and activities appropriate for fat intake reduction. We also organized an advisory committee composed of 15 professionals in related fields to discuss the adequacy and validity of the specific contents. Finally, we systematically organized the contents and developed children`s textbooks and teacher`s guidebooks. Considering the different cognitive development stages of junior and senior elementary students we developed two different textbooks for each of them which are easy to read and understand, fun to play with lots of activities, and designed to practice into daily life. The contents cover three major topics-the concept of lipid, lipid in food, lipid in life and are composed of 6 units in total. To help teachers understand and and to instruct, teacher`s guidebooks contain an overview of the education, specific information and practical guidelines for each class. We developed these education materials with the aim of lowering children`s fat consumption and eventually promoting their health welfare; hopefully we expect these materials would be useful for children`s nutritional education in the field.
