K2NiF4-type organic-based perovskites of the (C4H9NH3)2FexPb1-xCl4 (x=0.00, 0.25, 0.50, and 0.75) system have been synthesized using a low-temperatu re solution method under a flowing argon gas. When stoichiometric butylamine, iron chloride, and lead chloride are mixed, a yellow solution are obtained from slow cooling of 90 to -10 $^{\circ}C.$ The final product is a plate-like yellow crystal. The X-ray crystallographic analysis has been carried out using XRD in the range of $5^{\circ}{\leq}$ 2${\theta}$ ${\leq}80^{\circ}.$ The local symmetry around the absorbing Pb atom of the samples has been determined by the EXAFS spectroscopic study. The crystals assign to orthorhombic system by the XRD analysis. The FT-IR spectra are analyzed in the range of 600 to 3300 cm-1 . DSC and TGA are measured to detect thermal stability between 30 and 300 $^{\circ}C.$ Two endothermic peaks are detected in all samples. The electrical conductivity has been measured using the four-probes technique for the (C4H9NH3)2FexPb1-xCl4 system in 300-460 K. Photoluminescence phenomenon was also investigated at room-temperature.

The optimal design of auto-catalyst needs a good compromise between the pressure drop and flow uniformity in the substrate. One of the effective methods to achieve this goal is to use the concept of radially variable cell density. But this method has not been examined its usefulness in terms of chemical behavior and conversion performance. In this work, two-dimensional performance prediction of catalyst coupled with turbulent reacting flow simulation has been used to evaluated the benefits of this method n the flow uniformity and conversion efficiency. The results showed that two cell combination of 93cpsc and 62 cpsc was the most effective for improved pressure drop and conversion efficiency due to balanced space velocity and efficient usage of geometric surface area of channels. It was also found that large temperature difference between the bricks in case that the edge of the frontal face of brick has too much lower cell density(less than 67% of cell density of the center of the brick). This study has also demonstrated that the present computational results show the better prediction accuracy in terms of CO, HC and NO conversion efficiencies compared to those of conventional 1-D adiabatic model by comparison with experimental results.

The incidence of childhood obesity has increased dramatically. Childhood obesity is an increasing health problem because of its strong associations with chronic health problems in children and adults. These health problems significantly contribute to the development of common chronic diseases in later life, including hypertension, type2 diabetes, hyperinsulinemia, coronary heart disease, and other psychological disorders. So it is an important issue to prevent and treat obesity during childhood and adolescent. Diet and exercise are the cornerstones of treatment for obesity and related complications. For obese children, some clinical trials have shown improvement with diet, exercise, and /or behavioral interventions. Promising interventions for high-risk individuals, such as bariatric surgery and novel pharmacological agents, also require rigorous assessment with attention to long-term patient important outcomes. There are various pharmacological approaches to the treatment of obesity in the adolescent population some of which have FDA approval. In the article we discuss pharmacological approaches to guide the treatment of obesity in the pediatric population, including risks of treatment, monitoring of potential side effects.

The influence of nutrition during early life on physical growth as well as mental development has been thoroughly discussed in the literature. The physical dimensions of the body are greatly influenced by nutrition, particularly during the period of rapid growth in early childhood. Nutritional status affects every pediatric patient's response toillness. Good nutrition is important for achieving normal growth and development. It is indicated that permanent impairment of the central nervous system may result from dietary restriction of imbalance during certain periods of life. If children under 3 years of age show a good nutritional status, it may be assumed that they are well nourished. Several common diseases of children such as iron deficiency, chronic constipation and atopic dermatitis are known food related diseases. Patients with chronic illness and those at risk of malnutrition should have detailed nutritional assessments done. Components of a complete nutritional assessment include a medical history, nutritional history including dietary intake, physical examination, anthropometrics (weight, length or stature, head circumference, midarm circumference, and triceps skinfold thickness), pubertal staging, skeletal maturity staging, and biochemical tests of nutritional status. The use of age, gender, and disease-specific growth charts is essential in assessing nutritional status and monitoring nutrition interventions. Nutrition assessment and dietary counseling is helpful for the cure of disease, and moreover, the prevention of illness.

As household energy consumption has increased, serious environmental problems, such as resource depletion and global warming, are becoming global issues. It is essential to conduct the energy use of residents living in apartments in order to come up with alternative solutions for energy savings. Therefore, this study examined the energy use awareness of apartment residents and their energy use behavior by various types of awareness. To understand their energy use behavior according to the awareness of the subjects, the energy awareness dimension was created with five factors and they were subject to a cluster analysis; then, the subjects were categorized into three groups. Finally, the difference of energy use behavior was examined by groups of energy awareness. G1 represents the group that is indifferent to energy savings and believes that convenience is an important factor. Also, with respect to energy use behavior, this group tends to pursue convenience. G2 is the group that is conscious of energy use costs thereby enduring some inconvenience, and shows savings behavior in daily life and household affairs. Although, G3 is very aware of the significance for the necessity of energy saving, their energy saving behavior is relatively negative. Regarding these different characteristics of each resident group in their energy saving awareness and behaviors, diverse methods and promotion in energy education are required. Furthermore, an effective energy policy should be established based on the understanding of energy consumption.

Chronic abdominal pain, defined as long-lasting intermittent or constant abdominal pain, is a common pediatric problem encountered by primary care physicians and medical subspecialists. Chronic abdominal pain in children is usually functional, i.e., without objective evidence of an underlying organic disorder. Functional abdominal pain is categorized as functional dyspepsia, irritable bowel syndrome, functional abdominal pain, abdominal migraine, and aerophagia according to the Rome II criteria for pediatric functional gastrointestinal disorders. There is insufficient evidence to state that the nature of abdominal pain or the presence of associated symptoms can discriminate between functional and organic disorders. The presence of alarming symptoms or signs, such as weight loss, gastrointestinal bleeding, persistent fever, and chronic severe diarrhea, is associated with a higher prevalence of organic disease. Most children with chronic abdominal pain are unlikely to require diagnostic testing; such children often need pharmacologic and behavioral therapy.

다문화 사회에서 외국인을 위한 한국어교육의 방향

정수진(Jeong, Su-jin) 한국문화융합학회 2011 문화와 융합 Vol.33 No.-

이 글은 다문화 가정의 양적 팽창에 따른 한국 사회의 다문화적 현황을 살펴보고, 한국의 다문화 사회화의 한 축인 여성결혼이민자를 위한 한국어-문화교육 프로그램을 제안한 것으로, 주요 내용은 다음과 같다. 첫째, 현재 한국 사회는 국제결혼 건수 증가에 따라 다문화 가정이 늘어나고 있고, 이에 따라 다문화 가정의 자녀수도 증가 추세를 보인다. 이러한 현재의 상황에서 한국 사회에 절실히 요구되는 것은 다민족·다문화간의 언어적 소통과 문화적 화합을 가능하게 하는, 다문화 사회에 적합한 언어 (교육) 정책이다. 특히 비교적 교육의 수혜를 받기 어려운 지역 사회의 경우 다문화 가정에 대해서는 정책적 지원이 절실하다. 둘째, 한국어-문화 교육은 한국 사회의 일원이 된 이주민들이 사회적 소통을 성공적으로 이루고, 이들이 한국어 및 문화적 배경 지식을 체계적으로 갖추어 한국 사회에 안정적으로 정착하고 적응할 수 있도록 지원해 주어야 한다. 이와 더불어 한국어-문화 교육은 한국 사회 내 다문화 가정에 대한 인식을 개선하고 이들을 사회의 한 일원으로 받아들일 수 있도록 이들과 올바르게 소통하고 화합을 이룰 수 있는 통로를 마련해야 한다. This paper purposes to examine the status of multicultural society of Korea and to propose the Korean language-culture education programs for international marriage women and their families. For this purpose, chapter 1 reviews basic conceptions and importance of language policy based on the multiculturalism. In chapter 3 and 4 analysis and explanation are attempted on the direction of Korean education for multicultural families and the proposal for Korean-cultural education programs based on multiculturalism. The result of this analysis seems to prove that Koreancultural education programs support a settlement of international marriage women and their families and this settlement ultimately will contribute to reconciliation of multicultural society in Korea.

This paper purposes to explain construal and perspectival modes in terms of directions of viewing correlative events in Korean conjoined sentences. For this purpose, chapter 2 reviews basic notions and onceptions of ‘Construal’ and ‘Universal principels in Figure-Ground assignment to events in an interevent relation’, ‘Direction of Viewing’ suggested by Talmy (2000). Along with the theoretical background, in chapter 3 an analysis and explanation are attempted on how meaning and structure of Korean conjoined sentences are constructed; ① the scene the temporal complex consisting of two event is represented by coordinate conjoined sentence when the location of the perspective point of language user move itself from event1 to event2 and is represented by subordinate conjoined sentence when the direction of one’s viewing move from event1 to event2. ② the event in the Groundsubordinate clause is conceptualized as the basis, i.e. the earlier-occurring, cause, background or precondition for the event in the Figuremain clause, and that such assignment is reversed by perspective point of language user. The result of this analysis seems to prove that a meaning and a structure of conjoined sentences in Korean reflect how a language user construes a given context such as event and situation.
