Medications or conitive-behavior methods have been mainly used as a treatment of alcoholism, lately the virtualy technology has been applied to the kink of alcoholic disorders. A virtual environment makes him having avility to over come the drink. In this study, we were implemented by making panorama images and 3D object modules using 3D MAX. VRML, JAVA. And the BAR stimulator that composed with a position sensor, head mount display, and audio system, is suggested. To illustrate the physiological difference between a person who has a alcoholism and and without a liquor bottle, heart rate was measured during experiment, and also measured a person's HR after the virtual reality training. We demonstrated the subjective effectiveness of virtual reality psychotherapy through the clinical experiment.

한반도식물대(韓半島植物帶) 판별을 위한 표준종(標準種)에 관한 연구

유재은,백승언,김재수 명지대학교 자연과학연구소 2006 자연과학논문집 Vol.25 No.-

본 연구는 한반도의 삼림식물대 판별을 보다 더 쉽게 하고저 함에 주안점을 두고 연구하였다. 필자의 한사람인 白(2002)이 구분해 놓은 9개의 식물대를 기초로 하여 그 안에 있는 고유수종(固有樹種)과 각 식물대(植物帶) 안에서 분포의 남한계(南限界)와 북한계(北限界)를 이루는 수종을 찾아내어 한 쌍씩의 수종을 조합(組合)하여 복합표준종(複合標準種)으로 삼고, 그 상재도(常在度)를 계산하였으며 각 식물대의 적합도(適合度)를 비교하여 그 결과를 표 7에 표시하였다. 복합표준종의 선정은 각 산악의 단위구간내(單位區間內)에 공존하는 수종을 가지고 선정하였다. 이들 고유수종과 복합표준종에 의하여 보다 더 상세하고 구체적인 식물대(植物帶)의 적시(摘示)가 가능해졌다고 여겨지며, 이미 白(2002)의 연구에서 얻어진 판별식과 병용할 때에는 더욱더 정밀한 식물대의 판별을 할 수 있을 것으로 여겨진다. Selecting a proper indicator species is prerequisite for an efficient discrimination of plant zone in a certain geographical area. To select an indicator species applicable in the Korean Peninsula, the plant zone of the Korean Peninsula was divided into nine. In each plant zone, endemic species were surveyed, and the northern and southern boundary species were studied. The various combinations of northern and southern boundary species were used as compound indicator species and their applicability to distinct the plant zone in the Korean Peninsula were compared by analyzing their presence in each plant zone. The species existing together in the unit area of the mountains were selected as the compound indicator species. From the analysis, it was concluded that more detailed and concrete description for each plant zone was accomplished by the combinatorial application of edemic species and the compound indicator species. Thus it is expected that this improved method can be efficiently used to discriminate the plant zone in the Korean Peninsula.

The colorectal corcinoma is one of the most common malignant tumor in Korea and its carcinogenic mechanism has not been elucidated exactly yet. So far, the most common carcinogenic mechanism has been known to be multiple genetic changes. But, the CpG island hypermethylation has been revealed to be one of the most important carcinogenic mechanism second to the genetic changes. The epigenetic changes characteristically imprint and transfer to the next generation without changes of nucleotide sequences. When the CpG island of promoter or 5'- exon 1 of a specific gene is methylated by DNA methyltrasferases (DNMTs), the gene expression is inhibited. Carcinogenic mechansisms by promoter methylation has been well known, but the progression of the cancer has not been elucidated yet. The molecular researches on the carcinogenic mechanisms largely depended on the tumor tissue containing various components of cell, due to difficulties in harvesting pure homogeneous tumor cells. Promoter methylatonof the cancer related genes as APc, hMLH2, p16, DAP-K and MGMT in 50 cases of sporadic colorectal carcinoma was studied. The pure normal colorectal epithelial cells, and cancer cells from superficial and deep invasive portion were harvested respectively by laser captured microdissection(LCM), and DNA was extracted from them. The promoter methylation was studied by methylation specific poymerase reaction (MSP) after bisulfite modification of the DNA and the expression of the genes by immunohistochemistry. The results suggests that promoter methylation of the cancer related genes are closely related with the colorectal carcinogenesis and it occurrs from early phase of carcinogenesis, progressing constantly to the late stage. And the promoter methylation of normal epithelial cells increased by age. The p15, known to be the genes related to hematologic malignancy, was closely related to the colorectal carcinoma as well.

Today, many people stay lot of time sitting on chair in their life. If a sitting posture is not correct, there is some trouble with the waist. And if it goes on long time, sometimes it cause the hurts of waist or the deformded spinal column. A crouched posture is an obstacle to breath and it give rise to drowsiness because the lack of oxygen. Sitting posture is a habit so people can't feel it oneself and look over some kind of risks. It analyzes a condition of muscles by measuring EMG of spinal both side of spinal-bones. It can have a right sitting posture by the analyzing that increasing of muscles tention in one or the other side of muscles when the posture inclines on one side or ahead.
