결핵은 다양한 임상양상을 보이는 감염병으로 과거에 비해 많이 감소하였고 소아 결핵도 점차 줄어들고 있으나 여전히 중요한 감염병이다. 소아의 결핵은 성인과는 다른 임상적 특징을 가지며 폐외 결핵의 빈도가 성인보다 높고, 청소년의 결핵은 결핵균 감염에서 실제 질병으로 발전될 위험이 크다. 폐외 결핵 중 장결핵은 증상이 비특이적이고 다양하여 진단이 늦어질 경우 사망률 및 이환율이 높아질 수 있다. 크론병 또는 만성적인 소화기 질환과의 감별이 중요하며, 최근 대장 내시경의 발달로 감별 진단이 용이해지고 있다. 저자들은 6개월간 지속된 설사와 복통, 체중 감소와 간헐적이고 반복적인 $37.5-38^{\circ}C$의 발열로 내원한 12세 여아에게서 대장 내시경 검사를 하여 시행한 생검 조직의 PCR 검사와 조직학적 소견으로 장결핵을 진단하였고, 연이어 촬영한 흉부 방사선 상 활동성 폐결핵으로 진단되어 11개월간의 항결핵제 치료로 완치된 증례를 경험하였다. Intestinal tuberculosis (TB) is presented with nonspecific and variable clinical manifestations such as abdominal pain, diarrhea, fever and weight loss. Diagnosis of tuberculous enteritis may be missed or confused with many other chronic gastrointestinal disorders such as the Crohn disease and intestinal neoplasms. The diagnosis should be based on careful clinical evaluations, such as extra-intestinal signs and colonoscopic and histologic findings. Newer techniques such as PCR tests from the specimens through colonoscopic biopsy may be helpful to confirm diagnosis of tuberculous enteritis. The treatment regimens for pulmonary tuberculosis are generally effective for tuberculous enteritis as well. If not treated early, the prognosis of intestinal tuberculosis is poor. We report a case of tuberculous enteritis diagnosed by colonoscopic biopsy and TB PCR which was presented with diarrhea, abdominal pain, intermittent fever and weight loss in a 12-year-old girl with active pulmonary tuberculosis. The patient was treated successfully with antituberculosis agents for 11 months without any complications.

BaZr_0.85-xPd_xY_0.15O_3-_δ/ Carbonates 복합전도체 전기적 특성 연구

박가영,백승석,박준영,Park, Ka-Young,Baek, Seung-Seok,Park, Jun-Young 한국세라믹학회 2014 한국세라믹학회지 Vol.51 No.4

PdO-doped $BaZr_{0.85}Y_{0.15}O_{3-\delta}$ (BZPY) proton conductors have been proposed as applicable for intermediate temperature electrolytes for protonic ceramic fuel cells (PCFCs) because the PdO doping is effective for improving the proton conductivity of $BaZr_{0.85}Y_{0.15}O_{3-\delta}$ (BZY) with high affinity for hydrogen. In order to further improve the conductivity of BZPY, two-phase composite electrolytes consisting of a BZPY and molten carbonate were designed. Dense BZPY-based composite electrolytes were fabricated after sintering at $670^{\circ}C$ for 4 h, since molten carbonates fill the grain boundary of the porous BZPY matrix. Furthermore, BZPY/$(Li-0.5Na)_2CO_3$ composites show a significantly enhanced protonic conductivity at intermediate temperatures. This may be because easy proton transport is possible through the interface of the carbonate and oxide phase.

Inhibitory Effect of Dendrobium moniliforme on NO and IL-$1{\beta}$ Production in LPS-stimulated Macrophages

박가영,배창환,박순영,김지희,고우신,김영희,Park, Ga-Young,Bae, Chang-Hwan,Park, Sun-Young,Kim, Ji-Hee,Ko, Woo-Shin,Kim, Young-Hee The Society of Korean Medicine Ophthalmology 2009 한방안이비인후피부과학회지 Vol.22 No.3

석곡은 난초과의 여러해살이풀 Dendrobium moniliforme의 지상부를 건조한 것으로 예로부터 양위생진(養胃生津), 자음제열(滋陰除熱) 등의 효능이 있어 해열, 진통의 작용과 위액분비 촉진, 혈압강하의 작용이 있는 것으로 알려져 있다. 본 연구에서는 석곡의 항염증 작용 기전을 알아보기 위하여 석곡 열수추출물을 대식세포주에 처리하여 NO 및 IL-$1{\beta}$의 생성에 미치는 영향을 조사하였다. LPS로 자극된 대식세포주 RAW264.7 세포에서 석곡은 NO 및 IL-$1{\beta}$ 생성과 iNOS 단백질 발현을 저해하였으며, LPS에 의해서 활성화되는 ERK, p38, JNK 효소의 활성을 현저히 억제하였다. 이 결과들로 보아 석곡의 항염증 작용이 MAPK 활성 저해로 인한 NO 및 IL-$1{\beta}$ 생성의 억제 때문인 것으로 사료된다.

This study was conducted to investigate the quality characteristics of peach jelly following the addition of various gelling agents (locust bean gum, carrageenan, xanthan gum). The various gelling agents were added to peach jelly at five levels (1.0, 1.5, 2.0, 2.5 and 3.0%), after which their effects on physicochemical properties, textural properties and sensory qualities were investigated. The total titratable acidity (TTA) of peach jelly was decreased with increases in gelling agent. Additionally, the sweetness and pH of peach jelly increased significantly as the amount of various gelling agents increased. Moreover, the lightness (L-value), redness (a-value) and yellowness (b-value) of peach jelly was decreased as the amount of gelling agent. Furthermore, the hardness, gumminess and chewiness of the peach jelly increased as the amount of gelling agent increased. Finally, the overall acceptance was higher for jelly containing 2.0% added gelling agent than for other samples. Based on the results of this study, it is recommended that mixed gelling agents be added to peach jelly at 2.0%.

잠재범주분석을 이용한 원인적 영향력 추론에 관한 연구

박가영,정환,Park, Gayoung,Chung, Hwan 한국통계학회 2014 응용통계연구 Vol.27 No.7

관찰연구를 이용하여 인과관계를 추론할 경우 무작위 통제시험과는 달리 교란변수로 인한 편향을 제어하기 위한 통계적 전략이 필요하다. 최근에는 성향점수(propensity score) 를 이용한 짝짓기나 원인변수의 역확률을 가중치로 사용하는 주변구조모형이 제안되어 사용되고 있다. 이러한 인과관계 추론은 처치(treatment)가 명확히 주어진 경우에 교란변수를 통제하고 그 처치가 결과에 미치는 영향을 평가하는 방법에 초점이 맞추어져 있다. 하지만 기존의 방법의 경우 원인변수인 처치가 직접관측이 가능한 범주형 변수이고 결과변수 또한 직접관측이 가능한 변수인 경우에만 사용할 수 있는 한계를 갖고 있다. 본 연구에서는 원인변수인 처치와 결과변수의 결괏값의 직접적인 관측이 어려운 경우, 측정오차를 고려한 잠재범주모형(latent class analysis)의 변수로 모형화 함으로써 잠재범주 간의 원인적 영향력을 추정하는 방법을 제시하고자 한다. 그리고 미국의 The National Longitudinal Study of Adolescent Health 자료를 이용하여, 약물사용의 잠재범주에 대한 청소년기의 비행(delinquency)이라는 잠재범주의 원인적 영향력을 추정하였다. Unlike randomized trial, statistical strategies for inferring the unbiased causal relationship are required in the observational studies. Recently, new methods for the causal inference in the observational studies have been proposed such as the matching with the propensity score or the inverse probability treatment weighting. They have focused on how to control the confounders and how to evaluate the effect of the treatment on the result variable. However, these conventional methods are valid only when the treatment variable is categorical and both of the treatment and the result variables are directly observable. Research on the causal inference can be challenging in part because it may not be possible to directly observe the treatment and/or the result variable. To address this difficulty, we propose a method for estimating the average causal effect when both of the treatment and the result variables are latent. The latent class analysis has been applied to calculate the propensity score for the latent treatment variable in order to estimate the causal effect on the latent result variable. In this work, we investigate the causal effect of adolescents delinquency on their substance use using data from the 'National Longitudinal Study of Adolescent Health'.

This is a research of the costumes appearing in the Sunjo Muja Jinjak Uigwe for their digitalization through computer graphics. The bock is considered as one of the most important sources for our understanding of the court dance during the Joseon Dynasty. The costumes shown in the bock are classified for further analyses. And their structures and actual shapes of attires are suggested according to the different presentations in dancing. Both plane and three-dimensional appearances are shown through computer graphics. Through this study the following results are derived. First. the costumes as much as the dances themselves are as colorful and diverse to meet the established fame of Crown Prince Hyomyong as one of the most distinguished leaders in the arts of the Joseon Dynasty. He rearranged the already existing court dances and created new numbers for court entertainment. And for this purpose he produced matching costumes for the best of the performances, to be inherited until today through the sunk: Muja Jinjak Uigwe. Secondly, there are remarkable differences in costumes between the two banquets of February and June of 1828, although they are only four months apart. We can not only notice newly created costumes, but also find the completely changed costumes of the music director and musicians. Thirdly, this study discovered that there are differences between the court dance costumes from the costumes used today. There are some fundamental misunderstandings about the costumes themselves, as well as mistakes in wearing them. They can be the results from the lack of knowledge and understanding about the costumes, and demand urgent inter-disciplinary researches and contacts to solve the problems. This kind of research for the digitalization of Korea's traditional cultures can hopefully contribute greatly for the growth of culture contents industries in Korea.

박가영(Park, Gayoung) 조선대학교 민주평화연구원 2020 민주평화연구 Vol.3 No.1

The 1990s means the end of cold war in the North Hemisphere and also the fall of Apartheid in South Africa, meaning that the Caucasians in the country turned over the reigns of the Government to the colored people, such as Nelson Mandela. However, the policy of Apartheid has not disappeared in the residence styles and the language use as an official one in the country. This paper studies the topics of residence and language difference and discusses some solutions in and out of the country. The second chapter, with the help of detailed illustration and the magazine of Time, illuminates the unequal aspect as a legacy of Apartheid, and the third treats the similar contents in the language use. The conclusion throws the task of solving the problems. Too much inequality between the rich and the poor in one country goes to the international attention and goes to the universal problems, common homework as a human being.
