  • 선박 네트워크는 다양한 장치들을 네트워크로 연결하여 선박 상태를 실시간 모니터링 하고, 유지보수 비용을 최소화할 수 있다. 특히, 선박 네트워크에서 저비용, 저파워, 다기능의 센서 노드를 활용한 무선 센서 네트워크의 연구는 많은 장점이 있다. 본 논문에서는 선박 내의 무선 센서 네트워크 환경에서 에너지 효율을 고려한 클러스터 기반의 멀티채널 알고리즘을 제안한다. 제안하는 알고리즘은 분산적이고, 동적인 채널 할당 알고리즘을 이용해 클러스터 단위로 채널을 할당하기 때문에 클러스터 간의 간섭을 회피하고 처리율 및 에너지 효율의 향상의 결과를 보인다.

  • There are an increasing number of healthcare facilaties, especially branch offices, in rural areas to serve the aging population living there. However, there has been a gradual decline in the ratios of recognition, satisfaction and utilization by people who live in the regions. A significant reason of declining the ratios should be the population decline, but the most of population hierarchy shows the groups of elderly people over 60. This result appears to be limited to visit the public health centers. According to the result of population hierarchy, a branch office of public health center has been re-established as a complex welfare facility which can be fulfilled in the functions of basic medical supports and cultural supports. This research is focused on collecting the meaningful information of the status of physical facilities and utilization with 15branch offices of public health care centers in the rural regions near the city of Ik-San city. In addition, this research has a purpose of getting fundamental data for future architectural plans of the branch offices in rural regions with the results about the status of facility operation systems and users' needs.

  • 이 연구의 목적은 일제 강점기 경성도서관(京城圖書館)의 변천 과정을 밝히려는 것으로 한국과 일본의 문헌을 통해 비교·분석하였다. 연구대상은 1) 일본인 山口精(야마구치 세이)이 설립한 「일본인상업회의소」의 경성도서관 2) 윤익선 등이 취운정에 건립한 경성도서관 3) 이범승이 종로 탑골공원 옆에 세운 경성도서관이다. 이 도서관들을 개별적으로 고찰하였고, 동시에 이 세 도서관의 상호관계와 다른 도서관과의 관계 역시 살펴보았다. 연구결과, 山口精(야마구치 세이)의 경성도서관 장서는 이후 두 도서관에 일부 계승되었고, 두 도서관은 당대에 가장 활발한 공공봉사를 실천하였지만, 일제의 영향 하에서 독자적인 발전은 한계가 있었던 것으로 나타났다.

  • Ji-San, the founder of HyungSang medicine, emphasized food intake and detoxification by stating, "Korean medicine begins with detoxification." Toxin accumulates in one's body unless the internal and external conditions stay in their harmony. The accumulation of toxin is also caused by western medication or one-sided diet, and detoxification should be considered in those cases. HwangRyunHaeDok-Tang reduces fire and heat, and the lesion is likely to locate in the upper body. BangPoongTongSung-San can be used for systemic disease. IkWoon-San also reduces fire and heat but mainly focuses on promoting urination. InSamPaeDok-San has an effect of curing the external symptoms of SangHan(傷寒), in addition to detoxification. SeoGakJiHwang-Tang, SoDok-Eum, and SeoGakSoDok-Eum can resolve the heat-toxin when it is located on the surface. SibJeonDaeBo-Tang enhances the detoxifying function of human body. GhamDu-Tang and JaGeum-Jung have a general effect on detoxification.

  • Objective : The purpose of this study was to investigate the anti-inflammatory effects of Hwagae-san extract(HGSE) on the peritoneal macrophage. Methods : To evaluate anti-inflammatory effects of HGSE, We measured cytokines(interleukin-6; IL-6, interleukin-12; IL-12, tumor necrosis factor-${\alpha}$; TNF-${\alpha}$) and nitric oxide(NO) production in lipopolysaccharide(LPS)-induced macrophages. Furthermore, We examined molecular mechanism using western blot and also LPS-induced endotoxin shock. Results : 1. HGSE did not have any cytotoxic effect in the peritoneal macrophages. 2. HGSE reduced LPS-induced IL-6, TNF-${\alpha}$, IL-12 and NO production in peritoneal macrophages. 3. HGSE inhibited the activation of extracelluar signal-regulated kinase(ERK), C-Jun NH2-terminal kinase(JNK) but not of p38, degradation of IkB-${\alpha}$ in the LPS-stimulated peritoneal macrophages. 4. HGSE inhibited the production of TNF-$\alpha$, IL-6 and IL-12 in serum after LPS injection. Conclusion : These results suggest that HGSE may inhibit the production of TNF-${\alpha}$, IL-6, and IL-12 through inhibition of ERK and JNK activation, and that HGSE may be beneficial for inflammatory diseases.

  • The study was designed to investigate the effects of MokhwyangJoki-san Extract (MJSE) on the change of regional cerebral blood flow (rCBF) and mean arterial blood pressure (MABP) in normal rats, and further to determine the mechanism of MJSE. The results in normal rats were as follows ; MJSE significantly increased rCBF in a dose-dependent manner, and MABP did not change in a dose-dependent manner. This results were suggested that MJSE significantly increased rCBF by dilating pial arterial diameter. The MJSE-induced increase in rCBF was significantly inhibited by pretreatment with methylene blue (10 ${\mu}g/kg$, i.p.), an inhibitor of guanylate cyclase, and was not changed by indomethacin (1 ${\mu}g/kg$, i.p.), an inhibitro of cyclooxygenase. The MJSE-was not changed MABP was decreased by pretreatment with indomethacin but was not changed by methylene blue. This results were suggested that the mechanism of MJSE was mediated by guanylate cyclase.

  • 프루텔고치벌(Cotesia plutellae)은 내부기생봉이고 kB억제자 (IkB)와 유사한 유전자가 이 기생봉의 절대 공생바이러스(C. plutellae bracovirus: CpBV) 게놈에서 발견되었다. 이 유전자의 발현 부위는 417 br의 크기이며 138개 아미노산 서열 정보를 포함하였다. 이 단백질은 4개의 ankyrin 반복영역을 지니고 있었으며, 알려진 다른 폴리드나바이러스 유래 IkB 유전자와 높은 상동성을 보였다. 초파리 Cactus 단백질을 통해 대상 기주 IkB와 비교하여 보면, IkB 신호수신영역이 부재하는 구조를 보여, CpBV-IkB는 NFkB 신호전달체계의 비가역적 억제 인자로 작용할 것으로 추정되었다. CpBV-IkB는 프루텔고치 벌에 기생된 배추좀나방에서만 발현되었다. 정량적 RT-PCR 방법으로 CpBV-IkB의 발현량을 조사하여 보면, 기생 첫날부터 발현을 보이기 시작하여 뚜렷한 발현량을 기생 전체 기간동안 유지하는 양상을 보였다. 이 CpBV-IkB의 기능 분석이 간접적으로 이뤄졌으며, 이 유전자 발현물이 대상 기주 항바이러스 억제 인자로 작용할 것이라는 가설을 제시하였다.

  • Object : This study is designed to evaluate the correlation between the data of DITI(Digital Inrared Thermographic Imaging) examination and the changes of clinical symptoms after the therapy of acupuncture in the patients with spondylolisthesis. Contents : The conservative therapy with acupuncture was performed during 3-4weeks. The acupuncture points of BL23, BL24, BL25, BL40, BL57, BL60, BL62, GB30, GB31, ST36, TE3 was used. In the pre- and post therapy, DITI examinations were performed in patients who had spondylolisthes in L-spine X-ray and were treated by acupuncttare simultaneously, and then tried to correlate the results of clinical symptoms with the difference of thermographic findings at pre-and post acupuncture. Setting : The standard routine thermographic exanninations were performed with thermography (DITI) in the 22 patients with spondylolisthesis at pre- and post acupuncture. Patients : Thermographic imaging of 22 cases was analyzed. They had diagnosed spondylolisthes in L-spine X-ray. They were treated by acupuncture and moxibustion therapy in Wonkwang Oriental Hospital from May, 1998 to May, 2000. Results : 1) The causes were congenital (4.5%), overwork (31.85%), trauma (13.65%), degenerative factor(50%) 2) The DITI results showed 45.4% below $0.3^{\circ}C$, 36.4% between 0.3 and $0.5^{\circ}C$, 4.5% between 0.5 and $0.7^{\circ}C$, 9.1% between 0.7 and $0.9^{\circ}C$, and 4.5% over $0.9^{\circ}C$. 3) The results of treatment using pain scale showes that 27.3% of patientsachieved excellent recovery and 54.6% achieved good recovery. After compairing the DITI results before and after treatment, we found 45.4% of patients achieved excellent recovery and 36.4% achieved good recovery. Conclusion : Acupuncture showed good results over 81.9% in clinical evaluation and 81.8% in DITI. Thermographic examination was valuable in the evaluation of therapeutic effect of acupuncture treatment.
