소아의 소화성궤양은 소아 소화계질환 중에서 발병율이 점차 늘어나고 있는 추세에 있다. 최근 소아과에서 내시경의 활용이 활발해지면서 장기적으로 반복하여 위완통(胃脘痛), 변혈 (便血)및 구혈(嘔血)이 나타나는 경우 궤양성질환의 가능성이 높은 것으로 밝혀지고 있다. 본원에서는 유명한 중의사 왕붕비(王鵬飛) 교수의 비완통(脾脘痛) 치험방을 토대로 많은 임상을 거쳐 위평충제(胃平沖劑)를 개발하여 1992년6월부터 1997년12월까지 위내시경 검사를 통하여 위궤양으로 진단된 98명의 소아환자에게 투여하여 관찰한 바 만족스러운 효과가 나타나 이를 보고한다. 위평충제(胃平衝劑)의 처방구성은 자초(紫草), 청대(靑黛), 곽향(藿香), 유향(乳香), 회향(茴香), 정향(丁香), 황련(黃連), 적석지(赤石脂), 황정(黃精) 등이다. 한의학적 이론에 따르면 불규칙하고 자극성이 강한 음식섭취 습관은 비위(脾胃)를 손상시켜 중주(中州)를 옹체(壅滯)시키므로 기(氣)의 원활한 소통이 이루어지지 않으면 부통즉통(不通卽痛)의 기전으로 발전한다. 또한 근래 소아들이 각종 정신적인 압박으로 스트레스가 쌓이면서 간기울결(肝氣鬱結)을 초래하여 울화(鬱火)로 인하여 혈락(血絡)이 손상되면서 출혈증상이 나타난다. 왕교수의 견해에 따르면 체내에 어혈이 제거되지 않으면 기혈(氣血)의 순환이 더욱 악화되어 어적(瘀積)이나 궤양 또는 경새(梗塞) 등을 일으키게 된다고 하였다. 따라서 위평충제(胃平沖劑)는 활혈화어(活血化瘀), 청열해독(淸熱解毒)과 더불어 익기양위(益氣養胃), 거어지통(祛瘀止痛)의 효능이 있는 약물들로 구성되었다. 동물실험에서 위평충제(胃平衝劑)는 궤양표면을 보호하고 치유하며 재발을 방지하는 효과가 있는 것으로 확인되었고, 위액의 분비, 위단백질효소의 활성에 대한 억제 및 진통효과도 있는 것으로 입증되었다.행하여 사용하는 것이 바람직하며, 단순한 중약 투여는 일부 양약에 의한 소아성장에 미치는 영향을 피할 수 있어 더 많은 임상연구가 이어져야 한다.(當歸) 목단피(牧丹皮) 울김(鬱金) 정력자(?歷子) 세신(細辛) 오미자(五味子) 구기자(枸杞子) 산수황육(山茱黃肉) 황기(黃?) 감초(甘草) 등을 기본적으로 사용한다. 비신양허형(脾腎陽虛型)은 온보비신(溫補脾腎) 화어척담(化瘀滌痰)을 원칙으로 하며, 처방에는 구마황( 灸麻黃) 세신(細辛) 오미자(五味子) 당귀(當歸) 단삼(丹蔘) 울김(鬱金) 정력자(?歷子) 반하(半夏) 보골지(補骨脂) 선령비(仙靈脾) 태자삼(太子蔘) 황기(黃?) 감초(甘草) 등을 기본적으로 사용한다. 치험(治驗): (1) 천식의 실증(實證)은 치료를 한 뒤 완화단계에 접어들면서 허증(虛證)으로 전화되는데, 허천(虛喘)도 역시 천식이니 만큼 단순히 보법(補法)만 사용하여서는 안된다. 시종일관 천식치료에는 척담화어(滌痰化瘀)의 원칙을 지켜야 한다. 폐내(肺內)의 담어(痰瘀)가 철저하게 제거되어야 폐(肺)의 순환기능을 개선시켜 기도(氣道)의 염증을 신속히 흡수하고 치유할 수 있다. 이와 같은 치료과정은 약 3-6개월이 필요하다. 완화단계의 기간이 길어질수록 완치될 확률도 높아진다. (2) 급성기 천식은 폐(肺)를 다스려야 한다. 폐(肺)를 다스리는 방법에는 선폐(宣肺), 청폐(淸肺), 온폐(溫肺), 윤폐(潤肺) 및 척담거어(滌痰祛瘀) 등이 있다. (3) 증상이 완화되면 신(腎)을 다스린다. 천식은 신허(腎虛)가 근본적인 원인이므로 완화단계에서 심지어 발작기에도 보신제(補腎劑)를 추가하여 사용하면 배의 효과를 얻을 수 있다. (4) 비(脾)의 기능을 강화하여 근본을 채우는 부비배본(扶脾培本)도 중요하다. 후천의 수곡정미(水穀精微)로 선천을 충족시키고 자양하는 것은 질병에 대한 저항력을

Gelidium amansii shows antioxidant and anti-obesity effects; however, the effect on postprandial blood glucose levels is not known. The objective of the present study was to investigate the inhibitory effect of Gelidium amansii extract (GAE) on carbohydrate-digesting enzymes and its ability to alleviate postprandial hyperglycemia in streptozotocin (STZ)-induced diabetic mice. Gelidium amansii was extracted with 80% ethanol and concentrated for use in this study. The ${\alpha}-glucosidase$ and ${\alpha}-amylase$ inhibition assays were performed using the colorimetric method. ICR normal and STZ-induced diabetic mice were orally administered GAE (300 mg/kg body weight) or acarbose (100 mg/kg body weight) alone or soluble starch (2 g/kg body weight). Blood samples were taken from the tail vein at 0, 30, 60 and 120 min. Our results indicated that GAE markedly inhibited ${\alpha}-glucosidase$ and ${\alpha}-amylase$ activities with $IC_{50}$ values of $0.099{\pm}0.009mg/ml$ and $0.178{\pm}0.038mg/ml$, respectively, and was a more effective inhibitor than acarbose, the positive control. Further, the postprandial blood glucose levels of STZ-induced diabetic mice in the GAE-administered group were significantly lower than those of control group mice (p<0.05). Moreover, the area under the curves (AUC) significantly decreased with GAE administration in STZ-induced diabetic mice (p<0.05). These results indicate that GAE may be effective in decreasing postprandial blood glucose levels by inhibiting carbohydrate-digesting enzymes such as ${\alpha}-amylase$ and ${\alpha}-glucosidase$. Therefore, GAE could be used as a potential functional food for alleviating postprandial hyperglycemia.

In this study, Cyperus rotundus (C. rotundus) was fractionated into ethyl acetate to identify α-cyperone, a representative indicator, and its ethyl acetate fraction were evaluated to confirm the possibilityas a functional cosmetic ingredient. As a result of HPLC analysis, it was confirmed that the content of α-cyperone was 5.243%. In order to verify the inflammatory relief effect of the ethyl acetate fraction from C. rotundus (EAFC) and α-cyperone, it was confirmed that nitric oxide (NO) production inhibitory ability in RAW 264.7 macrophages induced an inflammatory reaction with lipopolysaccharide (LPS). Real-time qPCR analysis confirmed inhibition of mRNA expression level of inflammatory factors, IL-1β, IL-6, TNF-α, COX-2 and iNOS. As a results of conducting a clinical study using a simple cosmetic formulation containing EAFC, it was confirmed that the skin irritation stimulated by sodium lauryl sulfate (SLS) was calming and relieving itching. Through these results, it is believed that the C. rotundus can be used as a natural cosmetic ingredient that has the effect of inhibiting inflammation and relieving itching.

호안 Mattress/Filter는 철망구조 내에 채움재를 채운 다공성 구조로서 다양한 크기의 채움재를 사용할 수 있고 이로 인하여 다양한 공극을 형성할 수 있다. 이러한 Mattress/Filter의 다공성 구조는 통수성을 증가시키기 때문에 호안부에서 흐름의 에너지 및 유속을 감소시키며, 이로 인해서 소류력이 감소되어 호안의 침식을 완화시킨다. 또한 Mattress/filter에 사용되는 채움재는 자갈, 폐콘크리트 및 슬래그를 사용하기 때문에 표면이 거칠고 조도계수가 증가하게 되며, 호안에서의 조도계수의 증가는 유속의 감소와 소류력 감소를 가져온다. 한편 Mattress/Filter가 시공되고 수개월이 경과되어 식생발달 및 안정화가 이루어진 후에는 식생과 Mattress/Filter가 일체화되며, Mattress/Filter와 식생에 의해 조도계수의 증가 및 유속감소의 효과가 더욱 커지면서 결과적으로 소류력 감소효과는 증가하게 된다. Mattress/Filter의 다공성 구조는 호안의 통수성 및 조도계수를 증가시켜 호안부의 유속 및 소류력을 감소시키기 때문에 침식 및 식생유실을 완화시키게 된다. 시공 초기 식생이 발달하기 전에 복토된 토양의 유실 우려가 있을 경우 Mattress/Filter의 표면에 토양유실방지매트를 설치하여 복토된 토양이 유수에 의해 침식되는 현상을 방지할 수 있다. Mattress/Filter 시공후 수개월이 경과한 뒤에는 식생이 발달하여 유속 및 소류력 저감효과가 더욱 증가하며, 이로 인해서 더욱 안정된 식생군락을 형성시킬 수 있었다.

The purpose of this study was to offer a comprehensive analysis of the changing trends of the Korean income packaging, poverty rate, and level of income inequality from 1996 to 2002. In order to do that, this study used the micro-data of "Income and Expenditure Survey of Urban Households" by the National Statistical Office(NSO). Major results were as follows: (1) A ratio of public transfer in family income packaging increased at the DJ administration. (2) Poverty rate and Gini coefficient, which were 7.8% and 0.29 in 1996, rose to $8.8{\sim}10.4%$ and $0.30{\sim}0.34$ respectively during the year of 1998-2002. (3) However, poverty reduction effect and income inequality reduction effect of public income transfer increased preferably at the DJ administration. Those effects increased more since the enactment of National Basic Livelihood Security in 2000. Therefore, government should provide more national welfare programs to reduce the poverty rate and to improve better structure of income distribution.

In Korea, modern art therapy was developed in the 1960s and 1970s in the form of supplementary activities for patients in psychiatry. Along with the foundation of the Korean Association for Clinical Art in 1982 by psychiatric doctors, the therapy involved more various arts forms such as music, art, dance, poetry therapy, and psychodrama. More organizations with specific expertise opened such as the Korean Art Therapy Association, Korean Art Therapy Association, etc. in the 1990s and the Korea Arts Therapy Institute in 2001. As of April 2015, the members of the Korean Art Therapy Association total 15,000, including 6,200 regular members. The arts in integrative arts therapy (IAT) is an individual's creative activity which is related to his inner world, and the forms of IAT include music, drawing, dance and poetry therapy. From the aspect of phenomenology, IAT is psychophysical therapy involving the arts that helps patients recognize and perceive their experiences with an aim of at a recovery of the body and creativity from the phenomenological aspect. It is also a therapeutic activity that targets growth and development of the body and mind. Meta-analysis of the effects of art therapy with a focus on that involving music, drawing, dance movement and IAT in recent years in Korea, significant effects were observed in all factors but physical function. The biggest effect was mentality adaptation followed by activity adaptation and physiology. In the run up to the implementation of the daily flat-rate system for the health insurance reimbursement for palliative care in July 2015, the Ministry of Health and Welfare is reviewing the coverage of music therapy, drawing therapy and flower therapy, which are currently practiced by 56 hospice institutes in Korea. This is a meaningful step because the coverage of hospice and palliative care came after that of art therapy for psychiatric patients was approved in 1977. Still, there is a need clarify the therapeutic mechanism by exploring causality among the treatment media, mediation type and treatment effects. To address the issue of indiscriminately issued licenses, more efforts are needed to ensure expertise and identity of the licensed therapists through education, training and supervision.

Most of ferrous b.c.c weld materials may experience martensitic transformation during rapid cooling after welding. And it is well known that volume expansion due to phase transformation could influence in the case of welding of high tensile strength steels on the relaxation of welding residual stress. To apply this effect practically, it is a prerequisite to establish a numerical model which is able to estimate the effect of phase transformation on residual stress relaxation quantitatively. In this study, we investigated the effect of phase transformation on the relaxation of welding residual stress through experiment. And three-dimensional thermal elastic-plastic FEM analysis is conducted to reproduce the effect of phase transformation on the relaxation of welding residual stress. Also we carried out the analysis of welding residual stress in welds of similar or dissimilar steels considering the effect of residual stress relaxation due to phase transformation.

The real-time traffic information is considered to be the system to alleviate traffic congestion. An effective traffic information will help drivers make efficient travel decision, and network performance will be improved. To make efficient strategy of providing information, the analyst should quantify reduced congestion by the media traffic informations. Many other route diversion models considered only media-informations as information sources and ignored the impact of on-site informations such as visible delays and average speeds, which affect drivers' route diversion decision in practice. In those models, the effect of on-site informations could be treated to be the effect of media informations, and the effects of media informations would be over-estimated. The proposed model including the impact of on-site information can estimate the effect of media-informations. The results are expected to be applied to the analysis of traffic management policy such as ITS.
