Objective: The aim of this study was to investigate the prognostic factors and treatment outcome of patients with adenocarcinoma of the uterine cervix who underwent radical hysterectomy with systematic lymphadenectomy. Methods: A total of 130 patients with stage IB to IIB cervical adenocarcinoma treated with hysterectomy and systematic lymphadenectomy from 1982 to 2005 were retrospectively analyzed. Clinicopathological data including age, stage, tumor size, the number of positive node sites, lymphovascular space invasion, parametrial invasion, deep stromal invasion (>2/3 thickness), corpus invasion, vaginal infiltration, and ovarian metastasis, adjuvant therapy, and survival were collected and Cox regression analysis was used to determine independent prognostic factors. Results: An estimated five-year survival rate of stage IB1 was 96.6%, 75.0% in stage IB2, 100% in stage IIA, and 52.8% in stage IIB. Prognosis of patients with one positive-node site is similar to that of those with negative-node. Prognosis of patients with multiple positive-node sites was significantly poorer than that of negative and one positive-node site. Multivariate analysis revealed that lymph node metastasis, lymphovascular space invasion, and parametrial invasion were independent prognostic factors for cervical adenocarcinoma. Survival of patients with cervical adenocarcinoma was stratified into three groups by the combination of three independent prognostic factors. Conclusion: Lymph node metastasis, lymphovascular space invasion, and parametrial invasion were shown to be independent prognostic factors for cervical adenocarcinoma treated with hysterectomy and systematic lymphadenectomy.

In industry, an unsteady flow rate measurement of gases is becoming important increasingly. Our group has been developed an unsteady flow generator with an isothermal chamber for gases and showed that the calibration of the dynamic characteritics for the tested flow meter was effective. However, not only the measurement of the instantaneous flow rate value but also the evaluation of the time mean value in the unsteady flow becomes important in inustry. And it was difficult to control precisely the time mean value of the generated flow rate using the former unsteady flow generator which we developed. To solve this problem,our group developed an oscillatory gas flow generator with highly preciseinlet flow control system in 2008. In this research, to improve and clarify the precision of the generated flow rate with the oscillatory gas flow generator, we conduct to evaluate the performance of the in let flow rate control system with the sonic nozzle and the high precise pressure regulator. As a result, the highre producible results and stability were shown. Moreover, we perform the experiments and uncertainty analysis and confirm the effective of the suggested method.
ON THE CONSTRUCTION OF OPTIMAL LINEAR CODES OF DIMENSION FOUR
Atsuya Kato,Tatsuya Maruta,Keita Nomura 대한수학회 2023 대한수학회보 Vol.60 No.5
A fundamental problem in coding theory is to find $n_q(k,d)$, the minimum length $n$ for which an $[n,k,d]_q$ code exists. We show that some $q$-divisible optimal linear codes of dimension $4$ over $\bF_q$, which are not of Belov type, can be constructed geometrically using hyperbolic quadrics in PG$(3,q)$. We also construct some new linear codes over $\bF_q$ with $q=7,8$, which determine $n_7(4,d)$ for $31$ values of $d$ and $n_8(4,d)$ for $40$ values of $d$.

We are developing a novel home network system based upon the integration of information and energy. The system aims to analyze user behavior with a power-sensing network and provide various life-support services to manage power and electric appliances according to user behavior and preferences. This paper describes an electric appliance recognition method using power-sensing data measured by CECU (Communication and Energy Care Unit) which is an intelligent outlet with voltage and current sensors to integrate legacy appliances (which are incompatible with a communication network) within the home network. Furthermore, we demonstrate a prototype home energy management system and examples of services based upon appliance recognition.

Using human papillomavirus (HPV) as a subunit vaccine and its manipulation of surface loops is current trending research. Since the atomic model of L1 protein conformations were deciphered, their manipulations of epitopes bring multivalent vaccines. Here, in the present study, we have manipulated antigenic loops of HPV 6b L1capsid proteins in the amino acid regions 174 ~ 175(L1:174EGFP) and 348 ~ 349 (L1:348EGFP) with whole enhanced green fluorescent protein(EGFP), expressed in the silkworm larva using Bombyx mori nucleopolyhedrovirus (BmNPV) bacmid technology. The expressed proteins were partially purified using sucrose density-gradient centrifugation and size-exclusion chromatography (SEC). The display of EGFP in virus-like particles (VLPs) was confirmed by immuno-fluorescence microscopy, Western blots and immune-transmission electron microscopy (immuno-TEM). There was higher expression of EGFP incorporated L1:174EGFP than L1:348EGFP. Hydrodynamic diameter of VLPs was corroborated by dynamic light scattering,confirming the size of expected range of around 160 nm and substantiating the incorporation of EGFP. From immuno-TEM, each L1:EGFP VLP formed small particles,suggesting that small particles of L1:EGFP fusion protein were aggregated. Our study illustrates that incorporation of whole protein can efficiently form chimeric VLPs, without hindering the conformation. HPV L1 protein accommodated a whole protein on its antigenic loop as a small particle, but an inserted whole protein was unstable.
