This paper presents a cost-effective integrated 3D system that extracts the 3-dimensional foot data? to design the custom footwear. To measure the 3-dimensional data of the foot, a CCD camera and a Non-Gaussian laser line projector and optical triangulation method are employed. Furthermore, the integrated system employs a measurement base, a frame grabber, a CCD moving cart, a stepping motor and computer. The measurement result is saved as a 3D dxf foot data and a 2D eccensial data for a last design. The experimental results demonstrates that proposed? system have the descent resolution with 1mm which is enough for last and shoe design.

Object Web 基盤의 OSI 망 管理

김강석,송왕철 濟州大學校工科大學産業技術硏究所 1998 尖端技術硏究所論文集 Vol.9 No.2

The Object web translates the existing CORBA IDL into the Java language and uses IIOP for interaction between a client and a server under the exiting Web environment. The client and the server through the Object Web. do not use HTTP, a web protocol, but IIOP that is an inter-object communication protocol provided by the CORBA. This paper proposes an architecture which consists of a gateway, a CORBA manager and an OSI agent. The CORBA manager is based on Object Web and can manage MOs in the OSI domain. The gateway has a role to translate CORBA IDLS into CMIS service and vice versa. Hence, an OSI agent can be abstracted into a CORBA agent. In this architecture, any client with the Web browser can manage OSI MOs in distributed environment. The client can invoke the management operations through CORBA server after it download the Java applet from HTTP server.

A case of primary non-Hodgkin's lymphoma of scalp is presented. The patient is 16-year-old male who has develped 10×15cm huse scalp tumor on left frontal head with both cervical lymph node enlagement. The CT presentation of slightly isodense soft tissue mass lesion without rim enhancement on left scalp was found. Magnetic resonance imaging of head showed that tumors invaded outer table of the skull focally. There were no other extra cutaneous manifestations. Biopsy of tumor revealed diffuse poorly differentiated lymphocytic type of malignant lymphoma. The patient was treated with six cycles of COPBLAM-V chemotherapy that resulted in complete remission. Four months after the completion of chemotherapy, the left preauricular lymph node was enlarged. Biopsy revealed same pathology with that of scalp. Again he obtained a complete response with combination chemotherapy.

In the present study, onset conditions and transfer characteristics have been investigated experimentally through electrochemical technique. Cupric sulfate-sulfuric acid solution confined between two horizontal copper electrodes was used. The magnitude of current estimating transfer rate was measured at an adopted constant electrical potential. Due to the change of the polarity of electrodes, the diffusion and natural convection have been induced respectively. The dimensionless onset time and correlation equations were as follows. r=70.57Ra-? Sh=0.04731Fa? Above results have differences comparing with existing data which ignore the electrical migration effects. It is considered that the difference between ours and others comes from the effects of migration which we have applyed quantatively. Also, it is ween that the electrical migration not only retards the onset of natural convection, but reduces the transfer rates.

Recently, network management technology by delegation has been studied as a kind of network management technology to satisfy the user's requirements. Mobile Agent in the technology issues in the distributed network system. Mobile Agent is a software program which is able to move on network with mission for managing a NE(Network Element). Therefore, We have studied the efficient network management technology which is the network management system based upon Mobile Agent Using JNDI(Java Naming Directory Interface). JNDI is API(Application Program Interface) to support interface which make user's application program to be used the naming & directory service. We have designed and implemented the mobile agent network management system using JNDI. This Mobile Agent system is expected to provide a solution for the conventional centralized network system.

Background and Objectives: The aim of the study was to identify the factors associated with life satisfaction of hospitalized Vietnam veterans. Material and Methods: The data were collected from 200 hospitalized Vietnam veterans of 5 veterans hospitals in Korea from September 13 to 23, 2004. Information of general characteristics, health behavior, disease history, family function, depression and life satisfaction were collected by structured questionnaire. Results: The mean of life satisfaction was 21.48(±6.03), and the mean of depression was 53.10(±9.64). The prevalence of depression was mild depression 24.0%, moderate depression 43.5% and severe depression 25.0%. Depression was associated with life satisfaction and depression was higher, life satisfaction was lower. Family function and age were positively associated with life satisfaction, Conclusion: Life satisfaction was affected by depression and family function in hospitalized Vietnam veterans. Therefore, it was thought that psychosocial approaches such as improve depression and family function in care of hospitalized Vietnam veterans is required.

Ubiquitin D Promotes Progression of Oral Squamous Cell Carcinoma via NF-Kappa B Signaling

Song, An,Wang, Yi,Jiang, Feng,Yan, Enshi,Zhou, Junbo,Ye, Jinhai,Zhang, Hongchuang,Ding, Xu,Li, Gang,Wu, Yunong,Zheng, Yang,Song, Xiaomeng Korean Society for Molecular and Cellular Biology 2021 Molecules and cells Vol.44 No.7

Ubiquitin D (UBD) is highly upregulated in many cancers, and plays a pivotal role in the pathophysiological processes of cancers. However, its roles and underlying mechanisms in oral squamous cell carcinoma (OSCC) are still unclear. In the present study, we investigated the role of UBD in patients with OSCC. Quantitative real-time polymerase chain reaction and Western blot were used to measure the expression of UBD in OSCC tissues. Immunohistochemistry assay was used to detect the differential expressions of UBD in 244 OSCC patients and 32 cases of normal oral mucosae. In addition, CCK-8, colony formation, wound healing and Transwell assays were performed to evaluate the effect of UBD on the cell proliferation, migration, and invasion in OSCC. Furthermore, a xenograft tumor model was established to verify the role of UBD on tumor formation in vivo. We found that UBD was upregulated in human OSCC tissues and cell lines and was associated with clinical and pathological features of patients. Moreover, the overexpression of UBD promoted the proliferation, migration and invasion of OSCC cells; however, the knockdown of UBD exerted the opposite effects. In this study, our results also suggested that UBD promoted OSCC progression through NF-κB signaling. Our findings indicated that UBD played a critical role in OSCC and may serve as a prognostic biomarker and potential therapeutic target for OSCC treatment.

Theoretical Study on the Point Defects in N-Doped Anatase TiO2

In this work, first-principles calculations for the electronic and the optical properties of titanium dioxide (TiO2) with point defects are performed by using a plane wave pseudopotential method in the framework of the density functional theory and the generalized gradient approximation. The point defects, substitutional and interstitial nitrogen, in anatase TiO2 are investigated to understand the origin of the visible-light sensitivity of nitrogen (N)-doped TiO2. The results show that bands originating from substitutional N 2p states appear above the top of the valence band. These states tend to be delocalized and to mix with the valence band as the nitrogen concentration is increased. The optical absorption in the range between 400 and 700 nm is enhanced by the substitutional N impurities. The eect of interstitial N on the electronic and the optical properties of TiO2 depends on the interaction between the nitrogen dopants and the surrounding oxygen. The bonding between N and O introduces a series of localized occupied states under and above the upper valence band, and the electron transitions from these states improve the visible-light absorption of TiO2.
