우석 황종하(우석(友石), 인왕산인(仁王山人) 황종하(黃宗河) 1887-1952), 우청 황성하(又淸, 黃成河, 1891-1965), 국인 황경하(菊人, 黃敬河, 1895-?), 미산 황용하(美山 黃庸河, 1899-?)는 네 살 터울의 형제들이며 모두 서화가로 이름을 남겼던 인물들이다. 이들은 특별한 교육기관에 몸담지 않고 중국에서 유입된 화보나 선배 대가들의 작품을 보며 독학으로 그림 공부를 하였지만 각자 선호하는 기법과 잘 그리는 소재가 달랐다. 즉 황종하는 호랑이 그림을, 황성하는 지두화를, 황경하는 인삼도를, 황용하는 사군자화를 잘 그린 것이다. 각종 전람회나 전시회에 참여하는 태도에는 차이가 있었지만, 그들은 사형제전을 함께 개최하거나 합작도를 자주 제작하면서 형제간의 우의를 쌓아 나갔다. 특히 1922년에 그들의 고향인 개성에서 창립한 ${\ll}$송도서화연구회${\gg}$는 후배를 양성하는 교육기관이자 스스로의 작품을 소개할 수 있는 문화의 장으로 그 역할을 다하였다. 이렇듯 황씨 사형제는 서로의 생각과 취미를 공유할 수 있었던 친구들이였고, 동시에 각자 개성 있는 작품세계를 펼쳤던 예술가였다. 그리고 구한말에 태어나 역사의 격변시기를 경험하면서도 전통 한국화의 맥을 지켜왔고, 타계할 때까지 평생 지필묵을 고집하면서 글을 짓고 그림을 그리며 화제를 썼던 작가들이었다.

Acupuncture has fairly good weight-reducing effect in treating simple obesity due to the neuroendocrine regulation. In this study, the antiobesity effects of herbal acupuncture(HA) with Sang-hwang(phellinus linteus) at Fuai(SP16) were investigated in the rat fed on high-fat(HF) diet. Sang-hwang mushroom has been proven to have anti-carcinogenic effects and Sang-hwang extracts are highly effective in treatment and preventive treatment of AIDS, diabetes and high blood-pressure. To determine whether the Sang-hwang herbal acupuncture may have the anti-obesity effect, male Sprague-Dawley(4-wk-old) rats were fed a HF diet for 5 wk, which produced significant weight gain compared to rats were fed a normal diet, and then herbal acupuncture were treated for 3 wk in HF diet group. The body weight, food consumption, food effeciency ratio(FER), body fat mass, plasma nitric oxide(NO) were investigated in rats fed on normal diet, HF diet, and HF diet with HA(HF-diet-HA) groups. NO has been proposed to be involved in the regulation of food intake. In addition, the expression of appetite peptides such as orexigenic peptide neuropeptide Y(NPY) and the anorectic peptide cholecystokinin(CCK) were observed in the hypothalamus. HF-HA group reduced body weight gain, FER, body fat contents and NO concentration compared to HF diet group. The expression of NPY was reduced in arcuate nucleus(ARC), and CCK was increased in the paraventricular nucleus(PVN) after treatment of HA. In conclusion, Sang-hwang HA reduced adipocity, plasma NO and hypothalamic NPY, but increased CCK expression in the HF dietinduced obesity rat, therefore HA may have anti-obesity action through regulating body weight and appetite peptide of the central nervous system.

Objectives: Hyaluronic acid, high molecular glycosaminoglycan, exists in extracellular matrix of tissue, especially, in skin and has been known to be deeply involved in skin hydration. In this study, we investigated the effect of methanol extract of Hwang-gi, Astragalus membranaceus root, on hyaluronic acid production in human keratinocyte HaCaT cells. Methods: We determined hyaluronic acid synthase 2 gene expression and hyaluronic acid production in HaCaT cells by using RT-PCR and ELISA, respectively. Results: Hwang-gi extract didn't show the toxicity to HaCaT cells within the treated concentration and increased the hyaluronic acid synthase 2 gene expression and hyaluronic acid production. Conclusions: Hyaluronic acid production increased by Hwang-gi could be, partially, contribute to the moisturing effect in skin by it.

The support vector machine (SVM), first developed by Vapnik and his group at AT &T Bell Laboratories, is being used as a new technique for regression and classification problems. In this paper we present an approach to estimating approximate prediction intervals for SVM regression based on posterior predictive densities. Furthermore, the method is illustrated with a data example.

Supprot vector machine(SVM) is a new and very promising regression and classification technique developed by Vapnik and his group at AT&T Bell Laboratories. in this paper we provide a brief overview of SVM for regression. Furthermore we describe Bayesian model selection based on macKay's evidence framework for SVM regression.

This study aimed at investigating the effects of CPAP therapy on hypernasality in flaccid dysarthria. The subject was a flaccid dysarthric patient with hypernasality. An A-B-A experimental research design was used. The therapy program was conducted 16 sessions. During CPAP therapy, the subjects was required to repeat single-word utterances in the form VNCV. The results showed some improvement in decreasing hypernasality.
